PART I

Special Note Regarding Forward-Looking Statements

This report and other documents filed by us under the federal securities laws include, and future oral or written statements by us and our management may include "forward-looking" statements about our business, financial condition, operating results, or prospects within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve substantial risks and uncertainties. These statements include, among others:

forecasts of our anticipated future results of operations, cash flows or financial position;

statements concerning our completed, pending or proposed transactions, including with respect to the sale of our Mass Markets Fiber-to-the-Home business in 11 states (Arizona, Colorado, Florida, Idaho, Iowa, Minnesota, Nebraska, Nevada, Oregon, Utah, and Washington) (the "Territory") to a wholly owned subsidiary of AT&T Inc. ("AT&T"), investments, product development, Private Connectivity FabricSM ("PCF") and other network capacity buildouts, transformation plans, deleveraging plans, modernization and simplification initiatives, participation in government programs, and other initiatives, including benefits or costs associated therewith;

statements about our liquidity, profitability, profit margins, tax positions, tax assets, tax rates, anticipated tax refunds, asset values, contingent liabilities, growth opportunities, growth rates, acquisition and divestiture opportunities, business prospects, regulatory and competitive outlook, market share, product capabilities, impacts from regulatory and legislative developments, investment and expenditure plans, business strategies, securities repurchase plans, leverage, capital allocation plans, financing or refinancing alternatives and sources, and pricing plans; and

other similar statements of our expectations, beliefs, future plans and strategies, anticipated developments and other matters that are not historical facts, many of which are highlighted by words such as “may,” “will,” “would,” “could,” “should,” “plans,” “believes,” “expects,” “anticipates,” “estimates,” "forecasts," “projects,” "proposes," "targets," “intends,” “likely,” “seeks,” “hopes,” or variations or similar expressions with respect to the future.

These forward-looking statements are based upon our judgment and assumptions as of the date such statements are made concerning future developments and events, many of which are beyond our control. These forward-looking statements, and the assumptions upon which they are based, (i) are not guarantees of future results and are based on current expectations only, (ii) are inherently speculative, and (iii) are subject to a number of risks and uncertainties, many of which are beyond our control. Actual events and results may differ materially from those anticipated, estimated, projected or implied by us in those statements if one or more of these risks or uncertainties materialize, or if our underlying assumptions prove incorrect. All of our forward-looking statements are qualified in their entirety by reference to factors that could cause our actual results to differ materially from those anticipated, estimated, projected or implied by us in those forward-looking statements. These factors include, but are not limited to, the "Risk Factors" section of this Annual Report on Form 10-K, other portions of this report or other of our filings with the U.S. Securities and Exchange Commission (the "SEC").

Additional factors or risks that we currently deem immaterial, that are not presently known to us, or that arise in the future could also cause our actual results to differ materially from our expected results.

Environmental Stewardship and Sustainability

We believe our sustainability efforts support and promote the financial health of our business and strengthen relationships with our employees, communities, customers, and investors. As we continue to expand digital connections globally, Lumen remains dedicated to minimizing our environmental footprint.

We collaborate cross-functionally to implement our sustainability strategy in partnership with our Board of Directors and senior leadership. We work together to help meet our sustainability goals and regulatory obligations.

Environmental Sustainability Key Focus Areas include:

Environmental compliance and management: We assess and review our Company programs, operational facilities and waste management vendors. We monitor environmental legislative activity and collaborate with other internal groups to develop documented practices and procedures designed to support compliance with applicable laws and regulations.

Energy and emissions: In an effort to reduce our carbon footprint, we continue to identify and implement energy efficiency and greenhouse gas ("GHG") emissions reduction initiatives. We recently announced achievement of our 2018-2025 science-based GHG emissions-reduction targets. To guide the next phase of our sustainability journey, we have set new science-based GHG emissions reduction targets and developed an Energy Efficiency and Innovation Plan. We remain focused on exploring ways to reduce GHG emissions through our operational, customer and employee initiatives.

Water: Lumen uses the World Resource Institute’s Aqueduct Water Risk Atlas to assess susceptibility to future water stress across our areas of operation. We strive to reduce our water consumption, especially in water-stressed communities where we operate. We track our usage, monitor trends, and implement measures to enhance efficiency and reduce discharge.

Waste: We aim to reuse and recycle products, carefully manage our waste and minimize material use throughout our operations. We encourage customers to return their equipment to us, which is then either reused or sent to a certified recycler. This and other programs enable us to divert electronic and communications equipment from landfills.

As of December 31, 2025, we reported our products and services revenue among the following three categories for the Mass Markets segment:

Fiber Broadband: Under which we provide high speed broadband services to residential and small business customers utilizing our fiber-based network infrastructure;

Other Broadband: Under which we provide primarily lower speed broadband services to residential and small business customers utilizing our copper-based network infrastructure; and

Voice and Other: Under which we derive revenues from (i) providing local and long-distance voice services, professional services, and other ancillary services, and (ii) federal broadband and state support programs.

From time to time, we may change the categorization of our products and services.

Our Network

We deliver most of our products and services through our network consisting of fiber-optic and copper cables, high-speed transport equipment, electronics, voice and data switches, routers, and various other equipment. Portions of our network use leased assets, and much of the equipment uses licensed software.

Connectivity and Coverage

As of December 31, 2025, our network included over 340,000 route miles of fiber optic plant, most of which consists of "long-haul" fiber connections between major metropolitan areas, with the remainder being "metro" fiber that connects buildings within the metropolitan markets we serve. We also maintain copper-based network infrastructure and multiple gateway and transmission facilities used to operate our network across North America.

11

Table of Contents
As of December 31, 2025, our domestic network:

connected to approximately 163,000 buildings, which we refer to as “fiber on-net” buildings, located in 226 metropolitan markets serving our enterprise customer base;

connected to approximately 22.0 million broadband-enabled units capable of receiving our Mass Markets broadband services across 17 states;

connected to approximately 4.6 million of our 22.0 million Mass Markets broadband-enabled units capable of receiving services from our fiber-based infrastructure, with the remainder connected to the copper-based infrastructure; and

included central office infrastructure and supporting equipment that enables us to provide telephone service as an ILEC.

We sold portions of our network during 2023 and 2022 and recently completed an additional sale on February 2, 2026, as described above and discussed further in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and Note 2 — Divestitures in Item 8.

We calculate certain operational metrics (e.g., route miles, fiber miles, broadband subscribers) using internal methodologies that may differ from other industry participants.

Strategic Investments and Modernization

We view our network as one of our most critical assets. We have devoted — and will continue to devote — significant resources to maintain, modernize, and expand it. Key efforts include:

simplifying and modernizing our network and legacy systems;

retiring aging and obsolete infrastructure and systems; and

expanding our network to meet growing demand for enhanced and new products.

Leased Network Assets

Although we own most of our network, we lease a substantial portion of our fiber network from several other communication companies under arrangements that will periodically need to be renewed or replaced to support our current network operations.

Cybersecurity and Network Resilience

As a critical infrastructure provider, we and our customers face ongoing cyber threats, including advanced persistent threat actors. We experience occasional security incidents and service disruptions in the ordinary course of business and maintain robust systems to mitigate these risks. The development, maintenance, and operation of these systems and programs require significant investments and continuous updates to address evolving threats.

For additional information regarding our oversight of cybersecurity matters, see "Cybersecurity" in Item 1C, and regarding risks relating to our systems, network assets, network operations, capital expenditure requirements, and reliance upon third parties, see “Risk Factors” in Item 1A.

Competition

We compete in a dynamic and highly competitive market where demand for high-speed, secure data services continues to grow. Our competitors include global communications providers as well as systems integrators, hyperscalers, cloud service providers, software networking companies, infrastructure companies, cable companies, wireless service providers, device providers, resellers, and smaller niche providers. Intense competition is expected to continue across a wide range of industry participants amid the evolving market landscape.

12

Table of Contents
Our Success

Our ability to compete and succeed in this competitive environment depends on:

enhancing and integrating existing products;

introducing new offerings quickly and cost-effectively;

meeting changing customer needs;

delivering robust information security to build trust and mitigate cyber threats;

extending our core technologies into new applications; and

anticipating industry and technology shifts.

Competitive pressures are particularly strong when rivals have network assets better suited to customer needs, faster transmission speeds, lower prices, or a longer track record in the market.

Business

Enterprise and Wholesale Customers

We compete for enterprise and wholesale customers based on factors such as:

network reliability and comprehensive coverage;

data transmission speed and latency;

pricing and billing simplicity;

integrated service offerings;

IP network reach and peering capacity;

digital ordering capabilities and ease of use; and

customer service quality.

Pricing pressure remains significant as large communications companies and system integrators deliver high-speed fiber services, while other companies target price-sensitive customers with lower-cost, slower-speed non-fiber alternatives.

Mass Markets

Broadband Services

Competition to provide broadband services to our Mass Markets customers remains high. Market demand for our broadband services could be adversely affected by:

advanced wireless data transmission technologies (e.g., fixed wireless and low-earth-orbit satellites services);

continued enhancements to cable-based services; and

13

Table of Contents
newly established fiber-based networks built by competitors or municipalities, often supported by government subsidies.

Following the recent sale of our Mass Markets Fiber-to-the-Home business, we expect that broadband services will be a significantly smaller portion of our go-forward strategy.

Legacy Voice Services

Our legacy voice services face significant competition from wireless voice, social networking, videoconferencing, and messaging platforms as customers shift to these alternatives. Additional sources of competition include non-carrier systems capable of partially or fully bypassing our local networks through various methods. Software innovations have enabled low-cost networking alternatives, further reducing reliance on legacy voice networks. We anticipate that all these trends will continue to decrease use of our voice network.

Incumbent Local Exchange Carriers ("ILECs")

We operate various ILECs that are required under federal law to allow competitors to interconnect their facilities to the ILEC's network and to take other various steps designed to promote competition, including:

negotiating interconnection agreements in good faith;

providing nondiscriminatory “unbundled” access to portions of the ILEC’s network; and

permitting competitors to collocate facilities on the ILEC’s property either physically or virtually.

Consequently, our ILECs face competition from competitive local exchange carriers (“CLECs”). These CLECs typically provide competing services through:

reselling an ILEC’s local services;

using an ILEC’s unbundled network elements;

operating their own facilities; or

utilizing hybrid approaches of the aforementioned.

Additional information about competitive pressures is located under the heading “Risk Factors — Business Risks” in Item 1A.

Research, Development and Intellectual Property

As of December 31, 2025, we held approximately 2,500 patents and patent applications in the U.S. and other countries. We have also received licenses to use patents held by others. We plan to continue to file new patent applications as we enhance and develop products and services, and we plan to continue to seek opportunities to expand our patent portfolio through strategic acquisitions and licensing.

In addition to our patent rights, we have rights in various trade names, trademarks, copyrights and other intellectual property that we use to conduct our business. Our services often use the intellectual property of others, including licensed software. We also occasionally license our intellectual property to others as we deem appropriate.

For information on various litigation risks associated with owning and using intellectual property rights, see “Risk Factors — Business Risks” in Item 1A and Note 17 — Commitments, Contingencies and Other Items in Item 8.

Table of Contents
Regulation of Our Business

Our domestic operations are regulated by the Federal Communications Commission (the "FCC"), state regulatory commissions, and occasionally local agencies. Our non-domestic operations are regulated by supranational groups such as the European Union ("EU"), national agencies and frequently state, provincial, or local bodies. In most areas where we offer regulated services, we must obtain and maintain operating licenses from these bodies.

Changes in the leadership or structure of these regulatory bodies can significantly affect our revenue, expenses, competitive position or prospects. Because such changes are often difficult to predict, long-term planning is challenging.

This section highlights certain regulations affecting our operations, though additional regulations could have a significant impact. For additional information, see “Risk Factors” in Item 1A.

Federal Regulation of Domestic Operations

We are subject to extensive regulation by the FCC and state commissions, including obligations under the Universal Service Fund programs. The FCC regulates our interstate services, including business data service charges for wholesale network transmission and intercarrier compensation — such as interstate access charges billed to other communications companies for originating and terminating interstate phone calls and voice services, such as compliance with rules designed to protect consumers against unlawful automated calls or robocalls.

The FCC also regulates several aspects of our business related to international communications services, privacy, public safety, and network infrastructure, including:

our access to and use of telephone numbers;

our provision of emergency 911 services; and

our use or removal (potentially on a reimbursable basis) of equipment from vendors deemed to cause potential national security risks.

Failure to comply with FCC regulations can result in significant penalties. Many recently adopted FCC regulations remain under judicial review or subject to further rule-making, increasing the difficulty of determining the ultimate impact of these changes on us and our competitors.

Universal Service Fund

The federal government has introduced several programs to expand broadband access, including the Rural Digital Opportunity Fund (“RDOF”) program, an FCC initiative that provides federal financial support to fund broadband deployment in rural America. We were awarded RDOF funding in several of the states in which we operate and received payments for a period starting in 2022. In the third quarter of 2024, we relinquished rights to deploy services in RDOF census blocks in certain states, and in the second quarter of 2025, we voluntarily relinquished the remainder of our RDOF awards. As a result, we will no longer receive funding through the RDOF program and recognized a reduction to revenue of $46 million in our consolidated statements of operations in the second quarter of 2025. We also incurred fees of $49 million in connection therewith, which are reflected in our operating expenses within our consolidated statements of operations for the year ended December 31, 2025. In January 2026, we paid the $95 million of revenue and fees summarized above, along with an additional $4 million relating to our 2024 relinquishment as repayment of funds previously received and remittance of the fees incurred.

In 2024, a federal appellate court ruled that the FCC's universal service funding system, which levied fees against us and other telecommunication companies, was unlawful. The Supreme Court reversed that ruling, but the parties challenging the USF program have filed a renewed challenge asserting additional arguments. With judicial and legislative proceedings still pending, the ultimate impact of legal challenges and reform proposals on our operations remains uncertain.

15

Table of Contents
Other Federal Regulation

Federal officials have proposed changes to existing programs and laws that could impact our business, including proposals designed to increase broadband access, promote competition among broadband providers, and lower broadband costs. In late 2021, the U.S. Congress enacted legislation that appropriated $65 billion to improve broadband affordability and access, primarily through federally funded state grants. As of the date of this report, state and federal agencies continue working to distribute these funds to eligible applicants. We anticipate that the release of this funding may intensify competition for broadband customers.

For additional information about these programs, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Item 7 and Note 4 — Revenue Recognition in Item 8.

Broadband Regulation

The regulatory environment for broadband internet access service (“BIAS”) has shifted significantly in recent years, creating uncertainty about future requirements. Key developments include:

FCC classified BIAS as a common carrier service under Title II of the Communications Act of 1934 and imposed net neutrality rules in 2015;

FCC repealed the Title II classification and most of the net neutrality mandates in 2017;

FCC adopted a new order reclassifying BIAS as a Title II utility service and re-imposing net neutrality rules in 2024; and

a federal appeals court vacated the FCC's 2024 order, concluding that Congress did not authorize Title II regulations of BIAS in 2025.

Several states have proposed or enacted laws or orders focused on state-specific Internet service regulation. Certain members of Congress and consumer interest groups continue to advocate for classifying BIAS as a Title II utility service.

These developments create uncertainty regarding the future regulatory landscape for BIAS. Any increase in regulation could:

hinder our ability to operate our data networks efficiently;

restrict necessary network management practices to ensure quality service; and

increase the cost of operating, maintaining, and upgrading our network.

Collectively, these developments and potential regulatory changes could materially impact our operations and increase compliance costs.

State Regulation of Domestic Operations

State regulation of ILECs, including ours, has evolved significantly in recent years. Historically, ILECs have been regulated as “common carriers”, with state regulatory commissions exercising jurisdiction over intrastate voice telecommunications services and related facilities. While most states have reduced regulation, state regulatory commissions generally continue to:

set rates for traffic exchanged between telecommunications companies;

exercise some control over rates charged to customers for regulated services;

require ILECs to provide voice service throughout their territories, especially where alternative voice services are unavailable;

administer support programs subsidizing service in high-cost rural areas;
16

Table of Contents

regulate the purchase and sale of ILECs;

require ILECs to provide service under publicly-filed tariffs outlining terms, conditions, and prices of regulated services;

regulate ILECs’ ability to borrow and pledge their assets;

regulate transactions between ILECs and their affiliates; and

impose various other service standards.

In some states, switched and business data services and interconnection services remain subject to price regulation, though the extent varies by service type and geographic region. State agencies also regulate certain aspects of non-ILEC communications businesses, including determining carrier eligibility for federal universal service fund support.

Data Privacy Laws and Regulations

We are subject to numerous foreign, federal, and state laws governing the storage, maintenance, and use of customer data, including consumer protection, data protection, privacy, intellectual property, and other similar laws. These requirements are complex and vary widely across jurisdictions.

International Regulations

As a global service provider, we must comply with various jurisdictional data privacy regulations, including the EU’s General Data Protection Regulation (“GDPR”) and similar data privacy laws adopted in other jurisdictions of our international markets.

Domestic Regulations

Domestically, the number of state privacy laws continues to increase. The application, interpretation, and enforcement of these laws are often uncertain, and may be interpreted and applied inconsistently from jurisdiction to jurisdiction. These regulations require careful handling of personal and customer data and could have a significant impact on our business, especially if we violate any of those regulations.

Anti-Bribery and Corruption Regulations

As a global service provider, we are subject to complex foreign and U.S. laws governing business ethics and practices, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and other local laws prohibiting corrupt payments to government officials, as well as anti-competition regulations. To mitigate risk, we maintain compliance policies, programs, and training designed to prevent non-compliance with these anti-corruption and fair competition laws across all jurisdictions where we operate.

Regulation of International Operations

Our subsidiaries operating outside of the U.S. are subject to various regulations in the markets where we provide services. The scope and nature of these regulations vary by country and in some jurisdictions, communications regulatory frameworks are still developing and do not fully address many issues, including the pricing of services. Our overseas operations are also subject to various other domestic or non-domestic laws or regulations, including those governing:

exports and imports of various goods or technologies;

certain sanctioned business activities;

competition; and

cross-border data flows.

These requirements collectively shape our compliance obligations and influence how we conduct international operations.

Other Regulations

Our networks and properties are subject to numerous federal, state, and local laws and regulations, including those governing the use, storage, and disposal of hazardous materials, the release of pollutants into the environment, and the remediation of contamination. Our contingent liabilities under these laws are further described in Note 17 — Commitments, Contingencies and Other Items in Item 8.

Certain federal and state agencies, including attorneys general, monitor and exercise oversight related to consumer protection issues. We are also subject to codes that regulate our trenching and construction activities that require us to obtain permits, licenses, or franchises to operate. These regulations are enacted by municipalities, counties, states, federal government, or other regional governmental bodies and can vary widely across jurisdictions. In some cases, such regulations may require us to pay substantial fees or impose conditions that affect our network buildout initiatives.

Seasonality

Overall, our business is not materially impacted by seasonality. Our network-related operating expenses are, however, generally higher in the second and third quarters of the year. From time to time, weather-related problems have resulted in increased costs to repair our network and respond to service calls in some of our markets. The amount and timing of these costs are subject to the weather patterns of any given year but have generally been highest during the third quarter and have been related to damage from severe storms, including hurricanes, tropical storms, and tornadoes.

ITEM 1A. RISK FACTORS

The following discussion identifies material factors that could (i) materially and adversely affect our business, financial condition, results of operations or prospects or (ii) cause our actual results to differ materially from our anticipated results, projections or other expectations. The following information should be read in conjunction with the other portions of this annual report, including “Special Note Regarding Forward-Looking Statements”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and our consolidated financial statements and related notes in Item 8. All references to "Notes" in this Item 1A of Part I refer to the Notes to Consolidated Financial Statements included in Item 8 of Part II of this report. Please note the following discussion is not intended to comprehensively list all risks or uncertainties faced by us. Our operations or actual results could also be similarly impacted by additional risks and uncertainties that are not currently known to us, that we currently deem to be immaterial, that arise in the future or that are not specific to us. In addition, certain of the risks described below apply only to a part or segment of our business.

Business Risks

Challenges with integrating, modernizing, and digitally transforming our systems could adversely affect our business and financial results.

To achieve our operational and strategic goals and projected cost savings, we must integrate and modernize legacy systems, retire aging or obsolete platforms, deploy master data management, and complete our digital transformation to deliver a global digital platform with automated offerings and digital self-service. These initiatives require efficient resource allocation, advanced project management, adoption of emerging technologies (including AI), access to subject-matter experts, and cross-functional collaboration.

We cannot assure you these efforts will be completed on time, be within budget, or achieve intended benefits. Failure to execute could disrupt service delivery, delay repairs, reduce anticipated efficiencies, destabilize our network, and hinder compliance with regulatory or contractual obligations. These outcomes could result in customer loss, inability to attract new customers, and failure to meet financial objectives, any of which could materially and adversely affect our business and results of operations.

We may not realize the anticipated benefits of our strategic focus on PCF solutions.

We have prioritized sales from our PCF solutions in recent periods. PCF agreements involve delivery obligations and performance conditions that can affect timing and amounts of revenue recognition. Construction delays or cost overruns — from weather, supply chain, labor, permitting or other issues — could raise costs. Shifts in data center connectivity demand could reduce or even eliminate future PCF profitability. If anticipated benefits do not materialize or costs increase, our financial results may be adversely impacted.

Our attempts to capitalize on emerging market opportunities — especially AI — may fall short.

Growth in AI products and solutions, along with other recent industry changes have fueled demand for higher transmission speeds, greater bandwidth, lower latency and more advanced networking services. We are building a digital networking services ecosystem designed to deliver compelling products and services, including PCF solutions, that address market demand. Achieving this vision requires continuous system enhancements, seamless integration, and the ability to meet evolving customer needs amid rapid technological change and intense competition. If AI-related demand proves weaker, slower, or materially different from our assumptions in strategic plans or guidance, we risk misallocating resources and failing to meet growth objectives.

In connection with establishing our strategies and earnings guidance, we have assumed that the continued development of AI will continue to drive robust demand for our products and services, which subjects us to the risk of misallocating our resources if AI-related demand fails to meet current expectations.

The use of AI in internal operations may create governance, operational, cybersecurity, privacy, and regulatory risks that could adversely affect the Company's business and results of operations.

We operate in an intensely competitive industry, and existing and future competitive pressures could harm our performance.

Our Business and Mass Market offerings face intense competition from a broad range of providers under evolving market conditions that have increased both the number and diversity of competitors. Many of these competitors:

offer products and services that substitute for our legacy wireline offerings, including wireless broadband and voice or non-voice communication services;

provide a more comprehensive portfolio of communications products and services;

operate newer, more integrated, or more advanced systems that enable faster and more efficient service delivery;

possess greater financial, technical, engineering, research, development, marketing, and customer relationship resources;

conduct operations or raise capital at lower costs;

are subject to fewer regulatory constraints or costs;

benefit from stronger brand recognition and deeper, long-standing customer relationships; or

maintain larger-scale operations.

These advantages may allow competitors to compete more successfully for customers, strategic partners, and acquisition opportunities. In recent years, competitive pressures have commoditized pricing for certain products and reduced market prices for many others. We expect these pressures to continue, which could place further downward pressure on pricing and adversely impact our profitability.

Our ability to compete could be diminished if we fail to innovate and deliver advanced solutions timely.

The technology and communications industry is undergoing rapid technological change, increasing demand for digitally-integrated products and enabling an increasing variety of competitors to enter the market. These changes are reducing demand for certain services, enabling the development of competitive alternatives, allowing customers to bypass our networks, and compressing profit margins. Customers increasingly expect higher transmission speeds and advanced offerings, including traditional and generative AI services. Several competitors have committed substantial resources to developing these advanced services.

To remain competitive, we must:

accurately predict and respond to technological developments;

develop and offer attractive products and services that meet evolving customer needs;

migrate customers from legacy offerings to newer products and services;

provision our products and services quickly and reliably;

maintain and expand our network to support significantly greater transmission capacity and speeds; and

retire outdated services cost-effectively.

Our ability to achieve these objectives may be constrained by limitations in our network, technology, capital resources, or personnel. Failure to successfully execute these initiatives could result in resource misallocation and an inability to retain existing customers or attract new ones, which may adversely affect our business, financial condition, and results of operations.

Talent constraints and evolving work models could significantly impede our ability to attract, develop and retain qualified personnel and may impair execution of our transformation and strategic initiatives.

As we continue transforming to primarily serve Business customers and deliver advanced products, we face intense competition for skilled leaders and employees and may be unable to attract and retain the technical, operational, sales, and managerial expertise needed to execute our strategy. Competitors with greater resources may offer compensation and benefits exceeding ours, and remote work arrangements have broadened the pool of employers competing for talent. The relatively low trading price of our common stock has reduced the perceived value of our equity-based compensation programs, further hindering our ability to recruit and retain critical talent. Moreover, our significant remote and hybrid workforce could impair collaboration, innovation, and productivity, and weaken the collegial relationships that support our corporate culture. These factors could materially and adversely affect our ability to execute our strategic plans and achieve our business objectives.

Declining revenues and financial uncertainty could adversely affect our business.

Primarily due to competitive and technological changes discussed throughout this report, we have experienced prolonged systemic declines in several of our legacy services, including local voice, long-distance voice, network access, and private line revenues. More recently, pricing pressure and other factors have contributed to revenue declines across a broader array of products and services, including offerings marketed to our Business customers. Although we have implemented operating and strategic plans to address these challenges, we may not succeed in achieving future revenue growth within projected time frames, or at all. Many of our newer offerings generate lower margins and may displace higher-margin legacy services, further impacting profitability.

These revenue declines or failure to hit our revenue growth goals, combined with elevated debt levels and a relatively low trading price for our common stock, may create uncertainty about our future prospects and ability to meet obligations. Concerns about our financial condition may adversely affect employee morale and customers, vendors, landlords, lenders, and other third parties may be reluctant to transact with us or impose unfavorable terms if they believe our future is uncertain. Our relatively low stock price may also restrict our ability to raise capital through equity offerings and reduce analyst coverage. Any of these factors could materially and adversely affect our business, financial condition, results of operations, and prospects.

Damage to our reputation or brands could have a material adverse effect on our business.

Our Lumen and other brand names, together with our corporate reputation, are critical assets that support our ability to attract and retain customers and employees. These assets are vulnerable to significant harm from events such as customer or competitor disputes, cyber-attacks, service outages, data breaches, internal control deficiencies, performance failures, compliance violations, employee misconduct, government investigations, or litigation. Similar incidents involving competitors could also generate negative publicity for the entire industry, indirectly impacting our business.

Our reputation may further be impaired by criticism from customers, vendors, employees, advocacy groups, regulators, investors, the media, social media influencers, or others regarding our services, operations, or public positions. For example, unfavorable trends in customer experience scores — such as Net Promoter Score (“NPS”) or Customer Health Score (“CHS”) — relative to competitors could adversely affect us. Additionally, the risk of reputational harm associated with unauthorized disclosure of confidential information or customer data may increase if employees misuse social networking platforms or emerging technologies, including generative AI tools. Negative or inaccurate information about Lumen, even if based on rumor or misunderstanding, could also cause reputational harm.

Damage to our reputation or brands may be difficult, costly, and time-consuming to remediate. Any such harm could diminish the value and effectiveness of our brands, reduce investor confidence, and erode customer and employee loyalty, ultimately having a material adverse impact on the value of our securities.

We could be materially impacted by cyber-attacks.

As a critical infrastructure provider, our operations rely heavily on a broad range of hardware, software, networks and other products and services that are owned and managed by us or by third parties, including systems used to transmit and store large volumes of sensitive data (collectively, “IT systems”). We and our third-party partners and customers are frequent targets of increasingly sophisticated cyber-attacks, including distributed denial-of-service, ransomware, malware, viruses, credential harvesting, man-in-the-middle, software vulnerability exploitation, and social engineering. Our efforts to implement sound information security and business continuity programs cannot ensure the integrity of our systems and successful attacks could materially disrupt operations, compromise data, damage our reputation, trigger regulatory investigations or litigation, or result in significant costs. We have acquired and will continue to acquire companies that may have cybersecurity vulnerabilities or unsophisticated controls, which exposes us to significant risk.

We and certain of our third-party providers have previously experienced cyberattacks and security incidents. Future attacks could have a material adverse effect on our business, operations, or financial results.

As further described in Item 1C “Cybersecurity” of this annual report, cyber-attacks originate from multiple sources and manifest in diverse ways, potentially exposing personally identifiable information, customer data, or protected health information, subjecting us to stringent domestic and foreign data protection laws. These threats may also arise from failure or intrusions of unaffiliated third-party systems on which we materially rely to operate our business. Risks are heightened by factors such as:

our storage of digital information on Internet-connected servers;

use of open and software-defined networks;

complexity of our global network infrastructure, including harder-to-secure legacy systems;

rising demand for data services;

increasing customer scale and complexity of service requirements;

our large remote workforce;

our IT support obligations tied to divested businesses; and

escalating sophistication of threat actors.

Consequences of a successful attack could include operational disruption, data loss or exposure, regulatory penalties, reputational harm, customer attrition, service credits or costly retention incentives, costly remediation, litigation, and loss of certifications. Any of these outcomes could require us to notify customers, regulatory agencies or the public of data incidents and have a material adverse impact on our business, operations, or financial results.

Our role in global internet traffic makes us a continuing target for advanced persistent threats, including nation-state actors and other sophisticated threat actors. Risks are amplified by AI-driven attacks, widely available evasion and anti-forensic tools that make it increasingly challenging to detect, respond to, and recover from cyber attacks. Escalating geopolitical tensions and rivalries increase the likelihood of state-sponsored cyber-attacks against us. No defenses can guarantee prevention. Consequently, we expect to experience cyber incidents in the future. While past incidents have not had a material adverse effect on our business strategy, results of operations, or financial condition, we cannot guarantee that material incidents will not occur in the future. We continue to take steps designed to limit our cyber risks, and although we maintain cyber insurance, coverage may be limited by deductibles, exclusions, and caps, and may not fully offset losses.

Moreover, as a contractor to the Department of Defense (“DoD”), we are contractually required to protect “controlled unclassified information” and comply with the DoD’s cybersecurity requirements, including the security controls specified in the National Institute of Standards and Technology Special Publication 800-171 (“NIST SP 800-171”). The DoD has also begun phased implementation of the Cybersecurity Maturity Model Certification (“CMMC”) into its contracts. CMMC incorporates the requirements of NIST SP 800-171 and will require all contractors to, depending on the level of security required, perform a self-assessment or receive specific third-party certifications. If we are unable to protect controlled unclassified information or to achieve or maintain the required CMMC level, we may be deemed ineligible to bid on or perform certain government contracts. Noncompliance could also result in contract termination, reduced revenue, reputational harm, and increased costs associated with remediation and reassessment, any of which could materially harm our business.

Network, platform, or service failures could materially impact us.

From time to time, we experience outages in our network, hosting, cloud, or IT platforms, or failures of our products and services — including basic and enhanced 911 emergency services — to perform as intended. These disruptions expose us to many of the same risks described above for cyber-attacks and may lead to lost revenue, issuance of customer credits or refunds, complete customer loss, regulatory fines, and reputational harm.

We remain vulnerable due to factors such as aging infrastructure, human error, continuous changes in our network, introduction of new products and technologies, vendor and supply chain weaknesses, rogue employees, and hardware or software limitations. Remediation efforts may be more costly, time-consuming, disruptive, and resource intensive than anticipated. Future disruptions could lead to delayed sales, lower margins, fines, or customer attrition, any of which could have a material adverse impact on our business, reputation, results of operations, financial condition, cash flows, and stock price.

Our ability to conduct our operations is materially reliant on key suppliers, vendors, customers, and other third parties.

Our operations, financial performance, and liquidity rely significantly on key suppliers, vendors, licensors, customers, and other third parties. Disruptions or terminations of these relationships could have a material adverse effect on our business, financial condition, or results of operations.

Reliance on other communications providers: To deliver certain services within certain markets, we purchase services, lease network capacity, or interconnect with infrastructure owned by other communications carriers or cloud companies, some of which compete with us. These arrangements limit our control over service availability, delivery, and quality. We face risks that these providers may decline to renew agreements, impose unfavorable terms, or experience financial distress, including bankruptcy, that could impair ability to provide services. These risks are heightened when contracting with competitors, who may terminate agreements, increase prices, or prioritize their own traffic. In addition, some communications providers rely on our network to transmit their data or voice traffic. If these companies shift all or part of this traffic to alternative networks they own, build, or lease, our revenue could decline. For example, certain hyperscaler customers have developed infrastructure that has reduced their reliance on our network.

Reliance on key suppliers and vendors: We rely on a limited number of suppliers and vendors for critical equipment and services, including fiber optic cable, software, optronics, transmission electronics, digital switches, routing equipment, customer premise equipment and components, and operational support to assist with operating, maintaining and administering our business, including billing, security, provisioning and general operations. Our business could be adversely affected if these parties fail to deliver products or services on acceptable terms due to operational disruptions, increased pricing, security incidents, litigation, financial distress, bankruptcy, or strategic changes.

Reliance on key licensors: We license essential technologies from third parties to deliver certain products and services. These agreements may expire or be terminated, and future licenses may not be available on acceptable terms or at all. If a licensor faces intellectual property disputes or other challenges, our ability to use licensed technology could be impaired. Incorporating licensed technology into our network may also limit flexibility to deploy different technologies from alternative licensors.

Reliance on key customer contracts. We maintain several complex, high-value contracts with national and global customers. These contracts are subject to factors that may reduce or eliminate profitability. Failure to renew significant contracts upon expiration would adversely affect our results.

24

Table of Contents
Reliance on landowners: We require rights-of-way, colocation agreements, franchises, licenses, and other authorizations from governmental bodies, railway companies, utilities, carriers, and other third-party landowners to locate a portion of our network equipment over, on or under their respective properties, or to conduct operations within their jurisdictions. Many of these authorizations will expire within the next five to ten years unless renewed. Our operations could be adversely affected if authorizations lapse, are cancelled, terminated, allowed to expire, or become subject to material price increases. Network expansion may also be delayed if we cannot secure necessary permits or approvals. We cannot assure successful renewal or replacement of these arrangements.

Extreme weather and climate change could disrupt operations and increase costs.

Many of our domestic facilities are located in regions susceptible to severe weather and natural disasters, including tropical storms, hurricanes, tornadoes, earthquakes, floods, wildfires, or other casualty events. These events have disrupted operations in the past and may occur again, potentially causing significant damage such as downed transmission lines, flooded facilities, power outages, fuel shortages, network delays or failures, property and equipment loss, and business interruptions. Due to substantial deductibles, coverage limits and exclusions, and limited availability, we have typically recovered only a portion of our losses through insurance. Our system redundancy and other measures we implement to protect infrastructure and maintain operations may prove inadequate to sustain our operations following such events. Any such occurrence could result in lost revenue, litigation risks, reputational harm, and reduced profitability.

In addition, climate change may increase the frequency or severity of these events, heightening our exposure to operational disruptions and supply chain risks. Climate change could also require increased investment in network resilience and lead to additional regulatory requirements that may adversely affect our operations or financial results.

Our environmental, social, and governance programs and disclosures may expose us to legal, operational, and reputational risks.

We are subject to evolving and sometimes conflicting, laws, regulations, policies, and investor and other stakeholder expectations concerning environmental, social, and governance matters, such as environmental sustainability and climate change, both in the United States and internationally. Our environmental and sustainability initiatives, goals, and targets may be difficult to achieve and costly to implement. Increased required or voluntary disclosures regarding these efforts could subject us to scrutiny or criticism concerning their accuracy, adequacy, or completeness. In addition, in a climate where there are changing and increasingly divergent views on where our focus should be on these matters, our initiatives, goals, or commitments, or any revisions to them, are often criticized and the accuracy, adequacy, or completeness of such disclosures challenged. Failure — or perceived failure — to meet our environmental commitments or evolving stakeholder expectations could result in regulatory or legal proceedings, loss of customers or employees, reputational harm, or other adverse impacts on our business. Conversely, we may lose stakeholders who oppose such initiatives or face claims alleging these efforts caused harm.

We face other business risks.

We face additional business risks, including:

challenges in managing a global organization that offers a complex portfolio of products to a diverse customer base;

potential supply constraints, labor shortages, construction delays, or other factors that could impede our infrastructure buildout plans;

risk that sustained high vacancy rates in fiber on-net buildings we serve could reduce demand for our services; and

uncertainties and risks associated with acquiring or disposing of businesses or pursuing other strategic transactions.

Legal and Regulatory Risks

Complex and evolving regulations could increase operational and compliance costs.

As explained in greater detail elsewhere in this annual report, we are subject to numerous, often complex and occasionally conflicting laws and regulations at the international, federal, state, and local levels. We cannot assure that we will successfully obtain or maintain all authorization licenses necessary to operate in our markets, and full compliance cannot be guaranteed at all times. Even when authorizations are secured, the service standards and conditions imposed under these authorizations and related laws may increase costs, restrict operational flexibility, or expose us to third-party claims.

Governmental agencies, including state attorneys general, have routinely investigated our business practices in the past and are expected to continue doing so. These investigations have resulted in substantial fines and, in some cases, consent decrees that restrict future conduct and carry judicial enforcement risks. Breaching a consent decree could subject us to contractual remedies and contempt of court proceedings, any of which could have material adverse consequences. Future investigations could lead to litigation, penalties, operational changes, or reputational harm.

Our former or current participation in FCC buildout programs, such as RDOF, exposes us to significant financial risk. Noncompliance could result in significant penalties, forfeitures, or disqualification from future programs, materially affecting our financial condition. New subsidy programs, such as the $65 billion broadband fund established in 2021, may also increase competition in certain markets.

We provide services to various federal, state and local agencies. Failure to comply with complex regulations, laws, or contractual terms could result in penalties, negative publicity, suspension or debarment from future programs, or revocation of FCC licenses. Government agencies reserve the right to terminate contracts for convenience or lack of funding, which could materially impact our results of operations.

We are subject to numerous data privacy and security laws, including recently enacted or strengthened requirements in the EU and certain U.S. states. These laws are complex, frequently change, and often conflict across jurisdictions. Customers may impose additional requirements. Noncompliance could result in substantial penalties and reputational damage.

Due to the nature of our operations, we have been, and expect to continue to be impacted by regulatory developments related to climate change, including, for example, the direct regulation of greenhouse gas emissions or carbon policies that could result in a tax on such emissions. In addition, policy-driven changes in the prices of fuel or energy in geographies in which we operate could make it more expensive for us to purchase energy to power our networks and data centers.

Laws governing our operations have long been unsettled, limiting our ability to plan effectively. Regulatory uncertainty has increased following a 2024 U.S. Supreme Court decision eliminating judicial deference to agency interpretations of ambiguous federal laws. Future legislation or court rulings could impose burdensome requirements or liabilities. For example, our business could be materially impacted if U.S. Congress amends or repeals current federal limitations on the liability of private network providers, such as us, for third-party content stored or transmitted on private networks, as proposed by certain officials and consumer groups. We could also be significantly affected by initiatives to expand regulation of internet service providers or strengthen data privacy laws. Additionally, federal and state agencies that regulate support program payments and service fees may reduce the amounts we receive or can charge. Expanded regulation of 911 services is expected to increase costs and potential fines.

Finally, as a carrier of last resort for certain Mass Market customers, we may be required to provide services under economically disadvantageous conditions, diverting resources from other business priorities.

26

Table of Contents
We may face legal and reputational risks related to third-party content on our network.

Although our service contracts generally disclaim liability for third-party content, as a private network provider we could be subject to claims arising from content stored or transmitted on our systems. These claims may include allegations of defamation, invasion of privacy, copyright infringement, or facilitating prohibited activities such as online gambling or pornography. While we believe our liability is limited under current law, similar claims against other carriers have succeeded, and we cannot assure that our defenses would prevail. In addition, such content could result in negative publicity and harm our reputation. Furthermore, proposed changes to applicable laws could significantly increase our exposure and require us to implement measures to mitigate these risks.

Our pending legal proceedings could have a material adverse impact on us.

We are involved in several potentially material proceedings, including derivative and class action lawsuits. The outcome of these matters is inherently uncertain, and we may incur losses that exceed our recorded liabilities or insurance coverage. Any of the proceedings described in Note 17 — Commitments, Contingencies and Other Items in Item 8, as well as other current or future litigation, could have a material adverse effect on our business, reputation, financial position, operating results, the market price of our securities, and our ability to access capital. We cannot provide assurance regarding the ultimate impact of these matters.

We may not be successful in protecting and enforcing our intellectual property rights.

We rely on patents, copyrights, trade names, trademarks, service marks, trade secrets, and other intellectual property rights, as well as confidentiality agreements and procedures, to safeguard our proprietary assets. However, these protections may not be fully effective, including due to legal limitations and enforcement challenges. If we are unable to protect or enforce our intellectual property rights, our business, competitive position, operating results, and financial condition could be adversely affected.

Our use of AI technology may create operational, legal, and reputational risks.

We incorporate AI technology into certain products, services, and business processes. AI’s complexity and reliance on algorithms present risks that could lead to operational disruptions or other unintended consequences. Although we strive to use AI responsibly and attempt to identify and mitigate ethical and legal concerns, we may not identify or resolve issues before they occur. Risks associated with our use of AI include harmful or inaccurate outputs, bias, intellectual property infringement or misappropriation, defamation, privacy incidents, and cybersecurity vulnerabilities. In addition, emerging regulations in the United States, the European Union, and other jurisdictions could increase legal exposure or limit AI’s utility. For these reasons, our use of AI could materially harm our business, operations, or reputation.

Intellectual property claims could result in significant costs and operational disruptions.

We have in the past and may in the future receive notices or be named in lawsuits alleging infringement of third-party intellectual property rights. We have responded or will respond to these notices and claims when appropriate and expect this industry-wide trend to continue. If any of these claims are successful, we could be required to pay substantial damages, discontinue use of certain technology, or pay royalties to continue using it. These outcomes could reduce revenues or profit margins, impair operations, or require us to stop selling or redesign products or services, any of which could materially adversely affect our business. In addition, we may need to obtain rights to use third-party intellectual property to develop new products or services. If we cannot secure these rights on reasonable terms, our ability to introduce new offerings could be restricted, delayed, or made more costly.

Any actual or perceived failure to comply with new or existing laws, regulations and other requirements relating to the privacy, security and processing of Personal Information could materially impact our business.

In connection with running our business, we receive, store, use and otherwise process information that relates to individuals or constitutes “personal information,” “personal data,” “personally identifiable information,” or similar terms under applicable data privacy laws (collectively, “Personal Information”). We are therefore subject to a variety of federal, state and foreign laws, regulations and other requirements relating to the privacy, security and processing of Personal Information.

27

Table of Contents
The application and interpretation of such requirements are constantly evolving and are subject to change, creating a complex compliance environment. In some cases, these requirements may be either unclear in their interpretation and application or they may have inconsistent or conflicting requirements with each other. Further, there has been a substantial increase in legislative activity and regulatory focus on data privacy and security in the United States and elsewhere, including in relation to cybersecurity incidents. In addition, some such requirements place restrictions on our ability to process Personal Information across our business or across country borders.

It is possible that new laws, regulations and other requirements, or amendments to or changes in interpretations of existing laws, regulations and other requirements, may require us to incur significant costs, implement new processes, or change our processing of information and business operations, which could ultimately hinder our ability to grow our business by extracting value from our data assets. In addition, any failure or perceived failure by us to comply with laws, regulations and other requirements relating to the privacy, security and processing of information could result in legal claims or proceedings (including class actions), regulatory investigations or enforcement actions. We could incur significant costs in investigating and defending such claims and, if found liable, pay significant damages or fines or be required to make changes to our business. These proceedings and any subsequent adverse outcomes may subject us to significant negative publicity and an erosion of trust. If any of these events were to occur, our business, results of operations, and financial condition could be materially adversely affected.

Labor disputes or failure to renew collective bargaining agreements could materially affect our operations.

Many of our employees are represented by labor unions under collective bargaining agreements. While we maintain agreements with these unions, we cannot predict the outcome of future negotiations. Failure to reach new agreements could result in strikes, work slowdowns, or other labor actions that materially disrupt our services and increase costs. Even if new or replacement agreements are reached, they may impose significant additional costs that adversely affect our competitive position.

International operations expose us to regulatory, economic, and political risks.

Our international operations are subject to a wide range of U.S. and non-U.S. laws, regulations, treaties, tariffs, and governing our operations in international jurisdictions, either directly or indirectly through our contractual arrangements with other carriers. Many of these laws or directives are complex, frequently change, and may conflict across jurisdictions in which we provide services. These requirements could materially restrict our ability to provide services internationally or expose us to penalties, license revocations, or contract terminations if violated. In addition, increases in U.S. tariffs could result in additional costs that we may not recover from customers.

Beyond regulatory risks, conducting business internationally involves other challenges, including: economic, social and political instability, with the attendant risks of terrorism, kidnapping, extortion, civic unrest, potential seizure or nationalization of assets; currency and exchange controls, repatriation restrictions and fluctuations in currency exchange rates, problems collecting accounts receivable; the difficulty or inability in certain jurisdictions to enforce contract or intellectual property rights; reliance on certain third parties with whom we lack extensive experience; supply chain challenges; and challenges in securing and maintaining the necessary physical and telecommunications infrastructure. Any of these factors could materially adversely affect our operations and financial condition.

Allegations regarding lead-sheathed cables could result in regulatory or governmental actions, litigation, significant costs, and reputational harm.

Media reports in 2023 alleged that certain lead-sheathed cables in our copper-based network infrastructure pose public health and environmental risks. These allegations have led to regulatory inquiries and lawsuits and could result in legislative or regulatory actions, removal or compliance costs, or penalties. Accordingly, we may incur substantial expenses that could materially adversely affect our financial condition or results of operations. In addition, negative assertions about the health or environmental impact of our lead-sheathed cables — even if ultimately unfounded — could damage our reputation. Reputational harm may be difficult, costly, and time-consuming to repair and could negatively affect our business and the value of our securities.

Financial Risks

Our significant debt levels expose us to a broad range of risks.

We carry significant levels of debt and related debt service obligations, which could adversely affect us in several ways, including:

requiring us to allocate a large portion of operating cash flow to interest and principal payments, reducing funds available for other purposes, including acquisitions, capital expenditures, and strategic initiatives;

limiting our ability to capitalize on business opportunities or adequately respond to changing market, industry, or economic conditions;

increasing vulnerability to economic or industry downturns and interest rate fluctuations — particularly on variable-rate debt;

placing us at a competitive disadvantage compared to less leveraged companies;

negatively affecting perceptions of our company among customers, vendors, employees, creditors, and investors;

making it more difficult or costly to obtain future financing or refinancing, potentially forcing asset sales or other unfavorable actions to raise capital; and

heightening the risk of covenant breaches or missed payments, which could trigger acceleration of some or all of our outstanding debt.

These risks could be exacerbated by changes in economic conditions, additional borrowings, or credit rating downgrades. Subject to certain limitations, our existing debt agreements permit us and our subsidiaries to incur additional indebtedness.

Our ability to obtain future financing may be limited, and failure to refinance debt could adversely affect us.

We expect to periodically seek financing to refinance existing indebtedness and fund other needs. Our ability to secure additional financing depends on factors such as our financial position, performance, credit ratings, and debt covenants, and market conditions. Market conditions could be negatively affected by disruptions in global or domestic debt markets, geopolitical instability, trade restrictions, pandemics, weak economic conditions, or adverse developments in the communications industry. Periodic volatility and disruptions in capital markets have historically limited the ability of leveraged companies like ours to obtain debt financing. We cannot assure that additional financing will be available on acceptable terms, or at all.

If we are unable to make required debt payments or refinance our debt, we may need to consider alternatives such as selling assets, issuing additional securities, reducing or delaying expenditures, or negotiating debt restructurings. However, our debt agreements and market conditions may restrict or limit our ability to implement these actions on favorable terms, or at all. Even if implemented, these measures could negatively affect our operations, financial performance, or future prospects.

We have a highly complex debt structure, which could impact the rights of our investors.

Lumen Technologies, Inc. and certain of its subsidiaries owe substantial amounts under various debt and financing arrangements, some of which are guaranteed or secured by principal domestic subsidiaries that have pledged substantially all of their assets. Other debt is neither secured nor guaranteed. For example, most of Level 3 Financing, Inc.’s debt is secured by substantially all of its assets and guaranteed on a secured basis by affiliates, while other portions are guaranteed on an unsecured basis. Certain subsidiaries of Qwest Communications International Inc. also carry debt. Most of the subsidiaries of Lumen Technologies, Inc. have neither borrowed funds nor guaranteed any of our debt. As a result, determining the priority of rights among holders of our consolidated debt instruments is complex and depends on the assets and earnings of the issuing or guaranteeing entities. In addition, our debt is structurally subordinated to all liabilities of non-guarantor subsidiaries to the extent of the value of those subsidiaries that are obligors.

29

Table of Contents
As disclosed in the periodic reports for our subsidiaries, Level 3 Parent, LLC and Qwest Corporation, Lumen Technologies Inc. has intercompany debt arrangements with certain subsidiaries, including a revolving promissory note with Qwest Corporation that provides borrowing capacity up to a specified limit, and revolving loan agreements with Level 3 Financing, Inc., which include both secured and unsecured components. These arrangements are eliminated in consolidation under U.S. generally accepted accounting principles ("GAAP") and therefore do not appear on our consolidated balance sheet. These intercompany arrangements may be revised over time, including changes to borrowing limits.

Restrictive covenants and potential defaults under our debt agreements could materially affect our operations and liquidity.

Under our consolidated debt and financing arrangements, the issuer of the debt is subject to various covenants and restrictions, with the most restrictive applying to Lumen Technologies, Inc. and Level 3 Financing, Inc. These covenants limit our ability to incur additional debt or guarantees, pay dividends or other distributions to shareholders, make loans, create liens, sell assets, transact with affiliates, or engage in mergers and other strategic transactions. These restrictions could materially impair our ability to operate, restructure our business, issue priority debt, or pursue acquisitions and other strategic initiatives.

Lumen Technologies, Inc.’s senior secured credit facilities and secured notes also include financial maintenance covenants, as described in Note 7 — Long-Term Debt and Credit Facilities in Item 8. Level 3 Financing, Inc.’s agreements contain substantially similar limitations and treat it as a separate restricted group, which may significantly restrict transactions with Level 3 Parent, LLC, including cash transfers among affiliated entities. These restrictive covenants could have a material adverse impact on our ability to operate or reconfigure our business, to issue additional priority debt, to pursue acquisitions, divestitures or strategic transactions, or to otherwise pursue our plans and strategies.

We cannot assure you that we will be able to comply with these covenants. Failure to do so may result in an event of default, which could lead to the acceleration of substantial indebtedness, severely constrain our liquidity, and potentially force us to seek bankruptcy protection. Because certain instruments include cross-default and cross-acceleration provisions, a single default could trigger defaults across multiple agreements, significantly magnifying liquidity pressures.

Due to the complexity of our debt structure, covenants and operations, we have encountered, and may in the future encounter, disputes regarding our covenant compliance which, if not resolved in our favor, may cause a material adverse effect.

Our cash flows may not adequately fund all of our cash requirements.

Each segment of our business is very capital intensive. We expect to fulfill obligations under certain PCF agreements, and maintain, upgrade, and expand our network infrastructure and product offerings. These capital needs are influenced by factors such as:

evolving customer service requirements;

the need to maintain aging or obsolete infrastructure until replacement;

ongoing investments to enhance our network to remain competitive and meet demand; and

regulatory and contractual commitments.

Failure to make necessary capital expenditures could adversely affect our financial performance and prospects. In addition, we will require significant cash to meet fixed commitments and other objectives, including debt repayments, interest expense, operating costs, maintenance expenses, tax obligations, pension contributions, and other benefit payments. While recent PCF agreements have improved near-term liquidity, we cannot assure that future operating cash flows will be sufficient to fund capital investments, debt obligations, or other long-term cash requirements.

30

Table of Contents
Our ability to meet our obligations depends on cash flows from our subsidiaries.

As a holding company, substantially all of our income and operating cash flow is dependent upon the earnings of our subsidiaries and their distribution of those earnings to us in the form of dividends, loans or other payments. As a result, we rely upon our subsidiaries to generate cash flows in amounts sufficient to fund our obligations, including the payment of our long-term debt. Our subsidiaries are separate and distinct legal entities and, except where they have provided guarantees, have no obligation to pay amounts owed by us or to make funds available for our use. Subject to limited exceptions for tax or cash management purposes, non-guarantor subsidiaries are not required to provide us with cash through dividends, loans, or other transfers.

As discussed in greater detail elsewhere herein, restrictions under credit agreements, other contractual arrangements, and applicable laws limit the ability of certain subsidiaries to transfer funds to us, including Level 3 Parent, LLC and others. These restrictions include limitations on dividend payments. In addition, our rights to receive assets upon a subsidiary’s liquidation or reorganization are effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. Laws governing our subsidiaries generally restrict the amount of dividends they may pay, and future limitations could arise under tax laws, regulatory orders, or other regulations. For these reasons, you should not assume that our subsidiaries will be able to generate and distribute sufficient cash to meet our obligations.

We may not be able to fully utilize our NOLs.

We have substantial federal and state net operating loss ("NOL") carryforwards. Federal and state tax attributes, including NOLs, can be subject to annual limitations under the provisions of Section 382 of the Internal Revenue Code and similar state tax laws. If a corporation undergoes an “ownership change” within the meaning of Section 382, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change taxable income may be limited. We have experienced ownership changes in the past and we may experience ownership changes in the future as a result of future transactions in our common stock, some of which may be outside of our control. In an effort to safeguard our NOLs, we have maintained a Section 382 Rights Agreement (discussed in more detail below) which is scheduled to lapse in late 2026. Our state NOLs are subject to legal and practical limitations on our ability to realize their full benefit. We cannot assure you we will be able to utilize our federal or state NOLs as projected or at all.

Funding obligations for employee benefit plans could negatively impact profitability

Our company-sponsored benefit plans cover current and former U.S.-based employees, including active employees, retirees, and surviving spouses eligible for post-retirement healthcare benefits, as well as pension retirees and former employees with vested pension benefits. Currently, our domestic pension plans and other domestic post-retirement benefit plans are substantially underfunded from an accounting standpoint. We also maintain benefit plans for a much smaller base of our non-U.S. employees.

The cost to fund these pension and healthcare benefit plans for our active and retired employees has a significant impact on our profitability. Our costs of maintaining these plans, and the future funding requirements, are affected by several factors, including:

investment returns on funds held by our applicable plan trusts;

changes in prevailing interest rates and discount rates or other factors used to calculate the funding status of our plans;

increases in healthcare costs generally or claims submitted under our healthcare plans specifically;

the longevity and payment elections of our plan participants;

changes in plan benefits; and

the impact of the continuing implementation and modification of current federal healthcare and pension funding laws and related regulations.

31

Table of Contents
Increased costs under these plans could reduce our profitability and increase our funding commitments to our pension plans. See Note 11 — Employee Benefits in Item 8 for additional information regarding the funded status of our pension plans and our other post-retirement benefit plans.

Lapses in our disclosure controls and procedures or internal control over financial reporting could materially and adversely affect us.

We maintain disclosure controls and procedures designed to provide reasonable assurances regarding the accuracy and completeness of our SEC reports and internal control over financial reporting designed to provide reasonable assurance regarding the reliability of our financial statements and their compliance with GAAP. We cannot assure you these measures will be effective. Any failure or deficiency in these controls could result in inaccurate disclosures, financial reporting errors, or noncompliance with SEC requirements, which could materially and adversely affect our reputation, financial condition, or results of operations.

We face other financial risks.

We face other financial risks, including among others the risk that:

future intangible asset impairments could result in significant non-cash charges, reducing earnings and stockholders’ (deficit) equity and adversely affecting our financial condition;

persistent or rising inflation could adversely affect our business, potentially leading to lower customer demand, reduced profit margins, increased interest costs, and challenges in retaining personnel if wage expectations are not met;

downgrades in our credit ratings or unfavorable financial analyst reports regarding us or our industry could adversely impact the liquidity or market prices of our outstanding debt or equity securities;

higher prevailing interest rates would increase interest expense under our floating-rate debt;

a change of control of us or certain of our affiliates could accelerate a substantial portion of our outstanding indebtedness in an amount that we might not be able to repay; and

ongoing attempts of the U.S. Federal government, U.S. state and local governments, various foreign countries, and supranational or international organizations to reform taxes or identify new tax sources could materially impact our tax positions, and one or more of our ongoing tax audits or examinations could result in tax liabilities that differ materially from those recognized in our consolidated financial statements.

Divestiture Risks

We may not realize the anticipated benefits of prior completed divestitures, including the 2026 sale of our Mass Markets Fiber-to-the-Home business and our 2023 EMEA divestiture.

On May 21, 2025, we and certain of our affiliates agreed to sell our Mass Markets Fiber-to-the-Home business in the Territory. The transaction closed on February 2, 2026. In connection with the closing, we entered into various post-closing commercial agreements with the purchaser designed to ensure the continuity of customer services. In connection with divesting our EMEA business in 2023, we completed internal restructurings and entered into multi-year agreements with the purchasers to provide certain transitional services and to provide or receive certain commercial services. It can be and has been challenging and time-consuming to provide transition services, and we expect this will continue to be the case. Consequently, we may:

face disputes with purchasers regarding the scope or adequacy of transition services or the terms of our commercial agreements;

incur greater costs or fewer benefits than anticipated under post-closing agreements, including tax or other expenses;

experience increased vendor costs due to reduced economies of scale and other dis-synergies;

encounter operational distractions as segregation and support of divested businesses divert resources from the operation, digitization, and transformation our retained business;

sustain losses or inefficiencies from stranded or underutilized assets;

lose customers dissatisfied with post-closing services;

face talent challenges, including difficulty retaining or attracting personnel; and

experience operational challenges separating divested assets from retained assets.

Divestitures may not yield the expected benefits. We could incur greater tax or other costs, realize fewer benefits under the purchase agreement and related post-closing arrangements, or face operational challenges separating divested assets from retained assets. We may experience losses from stranded or underutilized assets, reduced future cash flows, and dis-synergies. We may not realize the expected proceeds, cash flows, or strategic benefits on the anticipated timeline or in the amounts projected. In addition, we remain subject to ongoing obligations and liabilities, including indemnification obligations, which could continue to divert resources and adversely affect our financial condition and results of operations.

These divestitures have reduced or will reduce our cash flows. If our remaining business underperforms, these effects could exacerbate other financial risks described elsewhere in this section, including our ability to meet cash requirements.

General Risks

Changes in government trade policies could adversely affect our business.

Changes in U.S. or foreign government policies may result in modifications to existing trade agreements, the imposition of new tariffs, or significant increases in existing tariffs on goods imported into the U.S., as well as retaliatory measures by foreign governments. The U.S. presidential administration has implemented or increased tariffs and signaled its intent to impose additional tariffs, but future actions by U.S. or foreign governments remain uncertain. A trade war or other governmental actions related to tariffs or trade agreements, as well as changes in social, political, regulatory, or economic conditions or laws governing foreign trade, manufacturing, development, and investment in countries where we operate, could negatively impact our business. In addition, any resulting negative sentiment toward the U.S. could further harm our operations, financial condition, or results of operations.

Unfavorable general economic, societal, health, or environmental conditions could negatively impact us.

Unfavorable general economic, societal, health or environmental conditions, including unstable economic and credit markets, or depressed economic activity caused by trade wars, epidemics, pandemics, wars, societal unrest, rioting, civic disturbances, natural disasters, terrorist attacks, environmental disasters, government shutdowns, political instability or other factors, could negatively affect our business or operations in a variety of ways.

We currently do not pay dividends to our common shareholders.

We discontinued paying dividends to our holders of common stock in 2022 and have no current plans to pay dividends in respect of our common stock for the foreseeable future. Not paying dividends could make the stock less attractive to certain investors, potentially impacting demand and share price.

Shareholder or debtholder activism efforts could cause a material disruption to our business.

While we value constructive input and regularly engage with our shareholders, activist shareholders may at times pursue proxy solicitations, submit shareholder proposals, or otherwise seek to influence our strategy or gain control over us. Responding to such actions can be costly, time-consuming, and disruptive to operations, diverting the attention of our Board of Directors and management from day-to-day operations. These impacts may be heightened if activist shareholders advocate actions that lack broad shareholder, Board, or management support. In addition, the recent rise in debtholders could increase the risk of claims under our debt agreements.

Our agreements, organizational documents, and applicable law could restrict another party’s ability to acquire us.

A number of provisions in our organizational documents and various provisions of applicable law or our Section 382 Rights Agreement may delay, defer or prevent a future takeover of us unless the takeover is approved by our Board of Directors. These provisions (which are described further in our Registration Statement on Form 8-A/A filed with the SEC on March 2, 2015) could deprive our shareholders of any related takeover premium.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

As a technology and communications company that globally transmits large amounts of information over our networks, we recognize the critical importance of maintaining the confidentiality, integrity and availability of information and systems under our control. Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise program to other key risk areas. We dedicate significant resources towards programs designed to identify, assess, manage, mitigate and respond to cybersecurity threats.

To identify, assess and mitigate cybersecurity risk, we have implemented a global information security management program that includes administrative, technical, and physical safeguards. This program seeks to identify, detect, protect against, and respond to threats to our information systems. Our security operations center provides advanced threat detection and response capabilities. We maintain an insider threat program to detect, investigate and mitigate insider threat risks to Lumen assets, data, services and personnel globally.

Our cybersecurity and privacy policies encompass information security, incident response procedures, and vendor management. Our risk management team works closely with our information technology, privacy, product, and operations departments to continuously evaluate emerging cyber risk as part of our overall risk management program. We monitor existing or proposed cybersecurity and privacy laws, regulations and guidance that are or may be applicable to us in the regions where we operate, including in the European Union and the United Kingdom where we are subject to the GDPR, as well as various other laws governing privacy rights, data protection and cybersecurity in other regions. As a U.S. government contractor, we are required to comply with extensive governmental regulations and standards regarding cyber security.

We periodically engage both internal and external auditors and consultants to assess and enhance our program and to assist in responding to cybersecurity incidents. Many of these independent external auditors and consultants are accredited under various information security standards, including those administered by the International Organization for Standardization and the PCI Security Standards Council. These engagements typically include penetration testing, third-party certifications, compliance assessments, audits, and assessments of vulnerabilities and emerging threats, as well as digital forensics and related work. We also periodically deploy our Internal Audit processes to conduct additional reviews and assessments. We also mutually exchange threat intelligence with government agencies, cyber analysis centers and cybersecurity associations.

As noted elsewhere in this annual report, we are materially reliant on a variety of third-party service providers to operate our business, which exposes us to the risk of cyber incidents impacting those providers’ systems. We have a vendor risk management program that assesses, manages and oversees risks associated with third-party service providers who have access to our data and systems. We engage in diligence, contracting or maintain ongoing monitoring for compliance with our cybersecurity standards, depending on our assessment of each provider's operational criticality and risk profile.

Despite our efforts to manage cybersecurity risks and prevent security incidents, (i) some of these attacks have resulted in security incidents (although thus far we do not believe that any of these incidents has resulted in or is reasonably likely to result in a material adverse effect on our business strategy, operating results, or financial condition) and (ii) future security incidents are likely (some of which could have a material adverse effect on our operating results or financial condition). See “Risk Factors” in Item 1A for a further discussion of cybersecurity risks and how they have affected or may affect us.

35

Table of Contents
We maintain an Incident Response Playbook that provides a set of guidelines for our stakeholders to follow when handling any data incident. This playbook describes how we assess incidents and how our security team shares information about such incidents with others at Lumen, including senior leadership and, if warranted, with some or all members of our Board of Directors. These escalation provisions, together with our disclosure controls and procedures, are designed to facilitate appropriate representatives throughout the Company in their assessment of relevant incidents and any necessary public notifications.

Our Cybersecurity Incident Response Team (“CIRT”) is responsible for detecting and coordinating responses to appropriate security incidents. This team regularly assesses its internal communication plan and meet as a team to discuss response options. The CIRT also addresses each incident, unless it determines that an incident is sufficiently serious. In those instances, it notifies our Cyber Security Watch Team (“CSWAT”), which is responsible for addressing cybersecurity incidents that raise more significant risks.

Our CSWAT comprises senior IT, operations, risk, legal and compliance leaders across business segments. In addition to addressing our more significant cyber incidents, the CSWAT manages risks from matters related to business continuity, including risks posed by cybersecurity threats, and implements controls to mitigate such operational risks. Among other processes, this team reviews our programs and processes related to information security, third-party risk, vendor management, facilities, unplanned downtime, business disruption, business continuity and disaster recovery.

Governance

As part of our overall risk management approach, we prioritize the identification and management of cybersecurity risk at several levels, including oversight by our Board of Directors, executive commitment, and employee training. Our Risk and Security Committee, comprising independent directors from our Board, assists the Board in overseeing our cybersecurity and data privacy risk. Specifically, our Risk and Security Committee, which meets quarterly, (i) receives periodic reports from our Chief Security Officer (“CSO”) on security programs, including incident reports, (ii) reviews cybersecurity risk assessments from information security, privacy, and internal audit management teams, including the adequacy and effectiveness of the Company’s internal controls regarding cybersecurity; (iii) reviews emerging cybersecurity developments and threats; (iv) reviews compliance with applicable laws and industry standards; and (v) periodically reviews our strategy to mitigate cybersecurity risks, such as our cyber insurance coverage and contingency plans in the event of security incidents or other system disruptions. At least quarterly, our Risk and Security Committee provides reports to the full Board of Directors regarding matters recently discussed by the Committee, which enables the full Board to provide additional oversight of our cyber risks and cyber processes. The full Board also reviews our cybersecurity risks in connection with its annual review of our enterprise risk mitigation programs.

Our CSO has extensive experience working in the public and private sectors leading security organizations, managing risk functions, and driving large information technology deployments. He has an Engineering degree, a Master of Business Administration, a Chief Information Security Officer Certification, and a Global Information Assurance Certification Security Leadership Certification. He oversees the implementation and compliance of our information security standards and is primarily responsible for managing our processes to assess and mitigate information security related risks.

Our cybersecurity organization includes a response team and management-level committees who support our processes to assess and manage cybersecurity risk as follows:

At the day-to-day operational level, we maintain an experienced information security team who are tasked with implementing our privacy and cybersecurity program and support the CSO in implementing our detection, reporting, security and mitigation functions. This team and the CSO work to develop and implement tools and processes designed to assist in identifying, containing and remediating cybersecurity incidents, and periodically retain consultants to assist with these activities. We generally seek to promote a company-wide awareness of cybersecurity risk through broad-based communications and educational initiatives, including regularly conducting phishing tests and holding employee trainings on our privacy, cybersecurity and information management policies, at least annually and more frequently when legal or other developments warrant.

36

Table of Contents
The Technology, Security, and Privacy Council, co-chaired by the CSO, the Chief Information Officer (CIO), and the Chief Privacy Officer (CPO), leverages the combined expertise of various security, IT, legal, internal audit, and operational leaders across the company. This council provides a forum for these cross-functional members of management of our leadership team to consider emerging technologies, such as artificial intelligence and emerging cybersecurity risks; review cybersecurity and privacy regulations; review and update policies and standards as appropriate; and promote cross-functional collaboration to manage cybersecurity and privacy risks across the enterprise. Members of this council are responsible for reporting on cybersecurity and privacy risks to the Risk Oversight Committee (“ROC”).

The ROC, whose core members include our Chief Financial Officer, Chief Technology and Product Officer, Executive Vice President of Enterprise Operations, and Chief Legal Officer, oversees our company-wide risk mitigation strategies. With respect to cyber risks, the ROC's oversight function helps to ensure accountability, adequacy of resourcing, implementation of Company directives, and alignment of oversight provided by our Board of Directors and our senior leadership team. Some of the more significant risks discussed by the ROC are also reported to our Risk and Security Committee at least quarterly.

OVERVIEW

We are a leading digital networking services company, empowering enterprise businesses to fuel growth in a multi-cloud, AI-first marketplace by connecting people, data, and applications quickly, securely, and effortlessly. We operate in a rapidly evolving landscape with growing demand for secure, high-speed connectivity. Our strategy focuses on growing and transforming our network and business to deliver next-generation solutions that meet these needs and build the backbone of the AI economy.

Reporting Segments

Our reporting segments are currently organized by customer focus.

Business segment: Serves enterprise and wholesale customers through five distinct sales channels: Large Enterprise, Mid-Market Enterprise, Public Sector, Wholesale, and International and Other. Revenue is reported under four product categories: Grow, Nurture, Harvest, and Other.

Mass Markets segment: Serves residential and small business customers. Revenue is reported under three product categories: Fiber Broadband, Other Broadband, and Voice and Other.

From time to time, we may change the categorization of our products and services. For additional information see Note 16 — Segment Information and Note 4 — Revenue Recognition in Item 8.

As of December 31, 2025, we served 2.4 million broadband subscribers under our Mass Markets segment. Our methodology for counting broadband subscribers may be different than the methodologies used by other companies.

2026 Divestiture

On May 21, 2025, we entered into a definitive agreement to sell our Mass Markets Fiber-to-the-Home business in the Territory to AT&T (the "Mass Markets Fiber-to-the-Home divestiture"). On February 2, 2026, we completed the Mass Markets Fiber-to-the-Home divestiture in exchange for pre-tax cash proceeds of $5.75 billion, subject to post-closing adjustments. In connection with the sale, we have entered into a transition services agreement under which we will provide to AT&T various support services and certain long-term agreements under which we and AT&T will provide to each other various network and other commercial services.

Current Business Environment and Macroeconomic Factors

The macroeconomic environment in which we operate remains dynamic and continues to affect our business. Key factors that have impacted us and our customers include:

Revenue mix: Shifts in technology and economic conditions have driven us to continuously review our strategy and as such, we expect to see continued reduction in legacy voice, broadband, and other legacy services, while fueling growth in our strategic products.

Inflationary pressures and build costs: Rising costs for labor, materials, and energy have increased operating expenses and capital expenditures, particularly to support our continued PCF buildout and other network transformations.

Supply constraints: Shortages of critical components and other materials have slowed certain network expansion efforts.

Customer behavior: Certain customers have delayed purchasing decisions, which has occasionally impacted sales cycles.

40

Table of Contents
To date, we do not believe these factors have materially impacted our financial performance or position. However, ongoing economic and geopolitical uncertainty, tariffs, inflation, and supply constraints could increase costs, reduce revenues, delay network expansion, or disrupt service delivery, which could materially impact our results. If these conditions persist, our projected cash flows and market capitalization could decline. For further information relating to these matters, see “— Trends Impacting Our Operations” below and "Risk Factors" in Item 1A.

We are actively managing these challenges through disciplined capital allocation, cost optimization, and strategic investments in network infrastructure. We believe these actions position us to navigate current macroeconomic conditions while pursuing long-term growth opportunities.

We expect continued demand for high-capacity, low-latency connectivity solutions, supported by enterprise digital transformation and government broadband programs. While macroeconomic uncertainty and competitive pressures present risks, we believe our transformation initiatives position us to deliver long-term value.

Trends Impacting Our Operations

Our operations are shaped by evolving technology, customer expectations, and market dynamics. Key trends that impact us, and will continue to impact us, include:

Automation and digital innovation: Growing demand for automated experiences and advanced technologies like AI and multi-cloud platforms requires ongoing investment in technology and infrastructure to enhance service quality and reduce costs.

Legacy decline and margin pressure: Legacy wireline services continue to shrink, while newer offerings often deliver lower margins — especially those involving third-party connectivity — necessitating cost optimization and pricing discipline.

Globalization and network expansion amid cost pressures: Distributed business models drive demand for high-capacity, low-latency networks. We are expanding our network capacity to capture growth, while managing vendor cost increases and dis-synergies from recent divestitures.

Monetizing network assets with execution risk: We aim to generate revenue through custom connectivity solutions, including PCF, by leveraging excess conduit and fiber assets. These opportunities can be significant but depend on market demand, regulatory conditions, and timely execution.

These and other developments and trends impacting our operations are discussed in "Risk Factors" in Item 1A and elsewhere throughout MD&A.

an offsetting increase of $26 million in professional fees; and

an offsetting increase of $17 million in employee-related expenses.

Selling, General and Administrative

Selling, general and administrative expenses increased $227 million in 2025 compared to 2024. This was primarily as a result of:

an increase of $72 million in hardware and software expenses;

an increase of $56 million in employee-related expenses;

an increase of $49 million in fees related to our voluntary relinquishment of FCC Rural Digital Opportunity Fund (“RDOF”) funding in the second quarter of 2025; and

an increase of $40 million related to a loss on the sale of operating assets in the first half of 2025 and recognition in the first quarter of 2024 of a deferred gain on the sale of select CDN contracts.

Goodwill Impairments

We are required to perform impairment tests related to our goodwill annually, which we perform as of October 31, or sooner if an indicator of impairment occurs. The classification of our Mass Markets Fiber-to-the-Home business as held for sale, as described in Note 2 — Divestitures in Item 8, was considered an event or change in circumstance which required an assessment of our goodwill for impairment as of April 30, 2025.

As of April 30, 2025, we had three reporting units for goodwill impairment testing, which are (i) Mass Markets, (ii) North America Business ("NA Business") and (iii) Asia Pacific ("APAC") region. When we performed our impairment tests during the second quarter of 2025, we concluded that the estimated fair value of our Mass Markets reporting unit was less than our carrying value of equity for this unit as of our testing date. As a result, we recorded non-cash, non-tax-deductible goodwill impairment charges aggregating to $628 million in the second quarter of 2025.

For a discussion of the goodwill impairment we recognized in 2025, see Note 3 — Goodwill and Intangible Assets in Item 8.

Mass Markets Segment Revenue

Mass Markets segment revenue decreased $235 million in 2025 compared to 2024 and decreased by $229 million in 2024 compared to 2023.

Mass Markets Product Categories

For 2025 compared to 2024, and for 2024 compared to 2023, the following were the primary drivers within each product category:

Fiber Broadband increased $148 million in 2025 and increased $98 million in 2024. This was primarily as a result of growth in fiber customers, primarily driven by our increase in enabled locations from our Quantum Fiber buildout, prior to our divestiture of Mass Markets Fiber-to-the-Home, as discussed further in Note 2 — Divestitures in Item 8.

Other Broadband decreased $218 million in 2025 and decreased $226 million in 2024. This was primarily as a result of fewer customers for lower speed copper-based broadband services.

Voice and Other decreased $165 million in 2025 and decreased $101 million in 2024. This was primarily as a result of continued loss of copper-based voice customers. 2025 additionally decreased $46 million due to the voluntary relinquishment of our funding received under the FCC's RDOF in the second quarter of 2025. See the Liquidity and Capital Resources—Federal Broadband Support Programs in this Part II Item 7 for more information.

LIQUIDITY AND CAPITAL RESOURCES

Overview of Sources and Uses of Cash

As a holding company, we rely on cash flows and capital resources from our subsidiaries to meet our parent-level liquidity needs. Access to subsidiary cash may be limited by debt terms, tax considerations, legal restrictions or other limitations; see "— Debt Instruments and Financing Arrangements" below and Note 7 — Long-Term Debt and Credit Facilities in Item 8.

Our primary source of liquidity is cash from operating activities. We also use our revolving credit facilities as a source of liquidity for operating activities and our other cash requirements. In addition, our recently completed Mass Markets Fiber-to-the-Home divestiture, which closed February 2, 2026, has generated significant cash proceeds subsequent to December 31, 2025, which have been primarily used to pay down debt as described below, but will also reduce our base of income-generating assets that generate our recurring cash from operating activities. Key uses of cash include operating expenses, capital expenditures, debt service, income taxes, share repurchases, pension contributions, and other benefit payments.

49

Table of Contents
Key balances as of December 31, 2025 included:

Cash and cash equivalents: $1.0 billion

Revolving credit availability: $722 million

Total consolidated indebtedness: $17.8 billion

As of December 31, 2025, $76 million of our cash and cash equivalents was held outside the U.S. Certain subsidiary debt covenants may limit upstreaming of cash. We currently believe there are no material restrictions on our ability to repatriate cash and cash equivalents into the United States, and that we may do so without paying or accruing significant U.S. or foreign taxes. Other than excess foreign cash held in India, we do not currently intend to repatriate to the United States material amounts of our foreign cash and cash equivalents. See Note 15 — Income Taxes for additional information.

We regularly review liquidity and capital allocation strategies with senior management and the Board of Directors, adjusting as strategies and conditions change.

Based on current assumptions, we believe our liquidity sources — operating cash flows, available cash, and credit capacity — will be sufficient to fund near-term requirements and strategic investments. For additional information on risks that could affect liquidity, see “Risk Factors — Financial Risks” in Item 1A.

Cash Flow Activities

The following table summarizes our consolidated cash flow activities:

Net cash used in investing activities(4,305)(2,830)1,475 
Net cash used in financing activities(1,319)(1,851)(532)

Operating Activities

Net cash provided by operating activities increased $405 million in 2025 compared to 2024. This was primarily as a result of:

an increase in working capital due to general timing variability, as described below;

an increase in deferred revenue related to receipt of advance cash payments pursuant to our recent sales of PCF solutions;

an offsetting decrease due to higher net loss adjusted for non-cash expenses and gains; and

an offsetting decrease due to the receipt of a federal income tax cash refund in the first quarter of 2024 which was not replicated in 2025.

Cash provided by operating activities is subject to variability period over period as a result of timing differences, including with respect to the collection of receivables and payments of interest expense, accounts payable, and bonuses.

For additional information about our operating results, see "Results of Operations" above.

50

Table of Contents
Investing Activities

Net cash used in investing activities increased $1.5 billion in 2025 compared to 2024. This was primarily as a result of:

an increase of $1.1 billion in capital expenditures; and

an increase due to $319 million lower proceeds from sales of property, plant and equipment, and other assets.

Financing Activities

Net cash used in financing activities decreased $532 million in 2025 compared to 2024.This was primarily as a result of:

an increase in net proceeds from issuance of long-term debt in 2025;

an offsetting increase in net payments of long-term debt and revolving debt in 2025 compared to 2024; and

an offsetting increase in debt extinguishment costs and fees, driven by the debt transactions in 2025 compared to those in 2024 described elsewhere herein.

See Note 7 — Long-Term Debt and Credit Facilities in Item 8 for additional information on our outstanding debt securities.

Short-term Liquidity Needs

As of December 31, 2025, we held cash and cash equivalents of $1.0 billion and had approximately $722 million of borrowing capacity available under our $954 million revolving credit facilities, net of undrawn letters of credit. These resources, together with cash generated from operating activities and any remaining proceeds from the Mass Markets Fiber-to-the Home divestiture, which closed February 2, 2026, represent our primary sources of liquidity for the next 12 months.

As of December 31, 2025, based on our current capital allocation objectives, we project expenditures for the next 12 months to include, among others, the following:

Capital expenditures: $3.2 to $3.4 billion, primarily for network modernization and fiber expansion.

Debt service: $51 million in scheduled term loan amortization and $37 million of finance lease obligations.

RDOF relinquishment: $99 million for remittance of awards and associated fees — see "Federal Broadband Support Programs" below for further details.

We expect to fund these expenditures primarily through operating cash flows, supplemented by available cash and borrowing capacity as needed. Based on current assumptions, we believe our liquidity sources will be sufficient to fund near-term requirements and strategic investments.

For additional information on short-term liquidity needs, see “Future Contractual Obligations” below.

51

Table of Contents
Long-term Liquidity Needs

Beyond the next 12 months, we plan to refinance a substantial portion of maturing debt through future debt issuances, subject to market conditions and covenant restrictions. Our ability to access capital markets depends on credit ratings and prevailing interest rates, and we cannot assure favorable terms for future borrowings. We may also consider other sources of liquidity, such as equity offerings or asset dispositions, depending on market conditions.

For additional information on our credit ratings and factors that may affect our access to capital markets, see “— Future Debt Transactions” below.

For additional information on long-term liquidity needs, see “Future Contractual Obligations” below.

Impact of Strategic Transactions on Liquidity

Our liquidity and capital resources have been influenced by several strategic actions aimed at optimizing our financial position, enhancing flexibility, and supporting long-term transformation initiatives. Key actions include:

Recent divestitures: The 2023 sale of our EMEA business and the 2026 sale of our Mass Markets Fiber-to-the-Home divestiture generated significant cash proceeds but reduced recurring operating cash flows. The Mass Markets Fiber-to-the-Home divestiture is also expected to reduce our Mass Markets fiber-related capital expenditures by approximately $1 billion annually. While this transaction is expected to reduce recurring revenue and operating cash flows, we believe it will sharpen our focus on enterprise and fiber growth and deliver significant cash proceeds to strengthen our financial position.

PCF agreements: Advance payments under PCF agreements increased operating cash flow and deferred revenue. These payments vary by quarter and fund network expansion and simplification projects, which will increase capital expenditures. We expect to enter into additional agreements in the future to sell products and services as part of our PCF solutions but cannot provide any assurances as to these additional agreements or the anticipated benefits thereof. See "Risk Factors" in Item 1A.

We expect these and future transactions to influence cash flows, leverage, and investment capacity. While divestitures provide immediate liquidity and PCF agreements support network expansion, they also introduce variability in operating cash flows. We will continue to pursue opportunities aligned with our capital allocation priorities and market conditions.

Capital Expenditures

We regularly invest in capital projects to expand and improve services, enhance and modernize networks, fulfill contractual obligations, and strengthen our competitive position. Discretionary projects are evaluated based on strategic impact such as revenue growth, productivity, service levels, customer retention, and expected return on investment. Capital spending is influenced by demand, contractual and regulatory requirements, cash flow, and resource availability. We expect capital spending to be focused on:

expanding our fiber network, including our other network capacity buildout plan;

modernizing and enhancing network efficiency and reliability;

developing new services; and

replacing aging network assets.

These investments aim to improve service quality, drive innovation, and position us to meet future demand.

For additional details on our capital spending, see "Risk Factors" in Item 1A and “Cash Flow Activities — Investing Activities” and “Impact of Strategic Transactions on Liquidity,” above.

Debt Instruments and Financing Arrangements

Debt Instruments

In 2025, we actively managed our capital structure through a series of transactions designed to enhance financial flexibility and optimize our debt profile to address upcoming maturities and support ongoing transformation initiatives. These transactions reduced consolidated indebtedness and extended our weighted-average debt maturity profile.

Liquidity and Credit Facilities Availability

As of December 31, 2025, we maintained $954 million of superpriority revolving credit facilities capacity, with none outstanding and $232 million in undrawn letters of credit, and $3.5 billion of drawn superpriority term loan facilities.

As of December 31, 2025, we had $234 million of total undrawn letters of credit, including $232 million issued under our revolving credit facilities and $2 million issued under a separate facility maintained by Lumen subsidiaries, the majority of which is collateralized by cash.

In addition to indebtedness under their above-mentioned credit agreements, Lumen and Level 3 Financing are indebted under their respective outstanding senior notes, and certain of Lumen's other subsidiaries are indebted under their respective outstanding senior notes.

For detailed terms, maturities, covenants, and outstanding balances, see Note 7 — Long-Term Debt and Credit Facilities in Item 8 and "— Other Matters" below.

Future Debt Transactions

Subject to market conditions, we expect to continue issuing debt securities as needed to refinance maturing obligations, including subsidiary debt, consistent with our capital allocation strategies and covenants. Availability, interest rates, and other terms of new borrowings will depend on credit ratings and market conditions, among other factors.

As of the filing date of this report, credit ratings for our and our subsidiaries' senior secured and unsecured debt were:

Income Tax Obligations

Net Operating Loss Carryforwards

As of December 31, 2025, we had approximately $982 million of U.S. federal NOLs that may be used to offset future federal taxable income. A portion of the NOLs are subject to annual usage limits under Section 382 of the Internal Revenue Code. We have a Section 382 Rights Agreement in place through late 2026 to help preserve our ability to use these NOLs. We expect to use substantially all remaining NOLs in future years, but we cannot assure you we will be able to utilize these federal NOLs as projected or at all.

See Note 15 — Income Taxes in Item 8 and "Risk Factors — Financial Risks — We may not be able to fully utilize our NOLs" in Item 1A.

Tax Law Changes

In July 2025, the U.S. enacted H.R. 1, also known as the “One, Big Beautiful Bill Act” (the “OBBBA”), which permanently allows 100% bonus depreciation, immediate expensing for domestic R&D, and favorable changes to interest expense limitations. These provisions did not have a material impact on our 2025 effective tax rate but are expected to significantly reduce our federal income tax liability. We filed a refund claim for approximately $400 million of federal estimated income taxes in July 2025 that we anticipate receiving in the first half of 2026.

The Organization for Economic Co-operation and Development ("OECD") has issued Pillar Two model rules introducing a new global minimum corporate tax of 15% for tax years effective after December 31, 2023. While the U.S. has not adopted Pillar Two legislation, certain countries in which we operate have already adopted legislation to implement Pillar Two. On January 5, 2026, the OECD announced the Side-by-Side ("SbS") package, implemented as administrative guidance and modifying the operation of Pillar Two rules that would fully exempt U.S.-parented groups from the application of certain Pillar Two top-up taxes. The SbS package also extends the current Transitional Country-by-Country Reporting ("CbCR") Safe Harbor by one year, through the end of fiscal year of 2027.The Pillar Two rules have increased our compliance requirements but did not materially impact our 2025 results. We continue to monitor evolving global and domestic tax legislation and administrative guidance.

Tax Payments and Refunds

In addition to the expected refund described above, in January 2024, Lumen received a $729 million federal income tax refund, including interest. Future tax payments will depend on many factors, including our future earnings, tax law changes, and any taxable transactions.

Pension and Post-Retirement Benefit Obligations

We maintain significant pension and post-retirement benefit plans that require ongoing cash outflows and could affect our liquidity and financial flexibility. These obligations are sensitive to market conditions and actuarial assumptions, and adverse changes could increase funding requirements and reduce cash available for other uses.

Current Status

As of December 31, 2025, our unfunded obligations were:

Pension plans: $588 million

Post-retirement plans: $1.7 billion

The expected long-term rate of return on pension assets, net of administrative expenses, was 6.5% for 2025 and is 6.5% for 2026. Actual investment performance may differ substantially from these assumptions, which could influence future funding needs. Lower asset returns or interest rates could increase our obligations and may require additional contributions, reducing cash available for other uses. For additional details, see “CRITICAL ACCOUNTING ESTIMATES — Pension and Post-retirement Benefits” in Item 7 and Note 11 — Employee Benefits in Item 8.
56

Table of Contents

Funding and Contributions

Benefits under the Combined Pension Plan are paid from its trust. Based on current laws and circumstances, we do not expect required contributions in 2026. Future contribution requirements will depend on factors such as investment performance, interest rates, demographics, plan changes, and funding regulations.

We may make voluntary contributions; none were made in 2025. We made a voluntary contribution to the trust for the Combined Pension Plan of $101 million in January 2026 and $170 million in 2024. Any required or voluntary contributions could reduce available cash and impact liquidity.

Settlements

We occasionally offer lump-sum settlements to certain former employees. Settlement accounting applies only when the total lump-sum payments exceed the settlement threshold, which equals the combined annual service cost and interest cost of the net periodic pension benefit expense. This threshold was not exceeded in 2025, 2024, or 2023. Future workforce reductions could result in annual lump-sum payments that trigger settlement accounting, potentially increasing earnings volatility.

Post-Retirement Benefits

Substantially all post-retirement health care and life insurance benefits are unfunded and paid from operating cash. Aggregate benefits paid under these plans, net of participant contributions and subsidies, were $172 million, $185 million, and $194 million for 2025, 2024, and 2023, respectively. In 2026, we currently expect to pay directly $181 million of post-retirement benefits, net of participant contributions and direct subsidies. See Note 11 — Employee Benefits in Item 8 for further discussion of expected future payments.

Future Contractual Obligations

We maintain obligations related to debt, leases, purchase commitments, and asset retirement, among others. Our estimated future obligations as of December 31, 2025 include:

Federal Broadband Support Programs

The FCC's RDOF program aims to support broadband expansion in rural areas throughout America. Although we initially agreed to participate in the program in certain areas, as previously disclosed, we voluntarily relinquished the entirety of our RDOF awards. As a result, we will no longer receive funding through the RDOF program and recognized a reduction to revenue of $46 million in our consolidated statements of operations in the second quarter of 2025. We also incurred fees totaling $49 million in connection therewith, which are reflected in our operating expenses within our consolidated statements of operations. In January 2026, we paid the $95 million of revenue and fees summarized above, along with an additional $4 million relating to our 2024 relinquishment as repayment of funds previously received and remittance of the fees incurred.

Federal officials continue to advance broadband‑related proposals, and Congress has authorized a $65 billion program to expand broadband affordability and access. State and federal agencies are in the process of implementing these initiatives, and we expect that the release of associated funding may increase competition in newly served markets.

For additional information on these programs, see Note 4 — Revenue Recognition in Item 8, "Business — Regulation of Our Business" in Item 1, and "Risk Factors — Legal and Regulatory Risks" in Item 1A.

Other Matters

We maintain cash management and intercompany loan arrangements with most of our income-generating subsidiaries. Under these arrangements, a significant portion of subsidiary cash is periodically advanced or loaned to us or our service company affiliate. We repay these advances as needed to meet subsidiary cash requirements; however, at any point in time, we may owe a substantial amount to our subsidiaries. In accordance with GAAP, these balances are reflected on the subsidiaries’ balance sheets but eliminated in consolidation and therefore do not appear on our consolidated balance sheet. For additional information, see “Risk Factors” in Item 1A.

Our network includes a limited number of legacy lead-sheathed copper cables. Previous media reports regarding potential health and environmental risks associated with these cables have led to regulatory inquiries and lawsuits, and may result in legislative or regulatory actions, removal costs, compliance costs, or penalties. As of December 31, 2025, we have not recorded any accruals for such costs and will only accrue such costs when they become probable and reasonably estimable. For more information on related litigation and risks, see Note 17 — Commitments, Contingencies and Other Items in Item 8 and “Risk Factors” in Item 1A.

We are also involved in other legal proceedings that could materially affect our financial position. See Note 17 — Commitments, Contingencies and Other Items in Item 8.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of our assets, liabilities, revenue, and expenses. Certain policies and estimates are considered critical because they involve significant judgments and assumptions and could materially impact our financial statements. These include:

goodwill and intangible assets;

pension and post-retirement benefits;

loss contingencies; and

income taxes.

While we believe our estimates are reasonable based on information available at the time they were made, actual results may differ and could be material.

58

Table of Contents
Goodwill and Intangible Assets

Historically, we had a significant amount of goodwill and have intangible assets that are assessed at least annually for impairment. As of December 31, 2025, intangible assets totaled $4.5 billion (excluding goodwill and intangible assets classified as held for sale), representing 13% of our total assets. Our remaining goodwill was fully impaired or reclassified as held for sale as of December 31, 2025. The impairment analyses of these assets are considered critical because of their significance to us and our segments, the subjective nature of certain assumptions used to estimate fair value, and because it can materially impact reported results and future expense.

Allocation and Amortization

Goodwill was allocated to our reporting units within the Business and Mass Markets segments when there is a change in composition. Intangible assets acquired in business combinations — such as goodwill, customer relationships, capitalized software, trademarks, and trade names — are recorded at estimated fair value at acquisition. Other intangible assets, primarily capitalized software, not arising from business combinations are initially recorded at cost.

Intangible assets without legal, regulatory, contractual, or other limiting factors are classified as indefinite-lived and are not amortized. For finite-lived intangible assets, we amortize using the straight-line method over the following estimated lives:

Customer relationships: 7 - 14 years

Capitalized software: 3 - 7 years

Other intangible assets: 9 - 20 years

The amount of future amortization expense may differ materially from current amounts, depending on the results of our annual reviews.

Impairment Testing

Goodwill

Goodwill is tested annually as of October 31, or more frequently if events or changes in circumstances indicate potential impairment. We first consider qualitative factors. If necessary, we perform a quantitative test comparing the reporting unit’s estimated fair value to its carrying amount. If fair value is lower, we record a non-cash impairment charge for the difference.

Prior to the Mass Markets Fiber-to-the-Home business divestiture, we had three reporting units for goodwill testing: Mass Markets, NA Business, and APAC. Prior to the divestiture in 2023, the EMEA region was considered its own reporting unit. Our reporting units are not discrete legal entities with discrete full financial statements. Reporting units share assets and liabilities, which are allocated based on relative revenue or EBITDA. These allocations can materially affect fair value estimates. For each reporting unit, we compare its estimated fair value of equity to the carrying value of equity that we assign to the reporting unit.

Intangible Assets

Finite-lived intangible assets are evaluated for impairment when triggering events or changes in circumstances occur.

Fair Value Estimation

Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method and (ii) a market approach.

59

Table of Contents
Discounted Cash Flow Method

Under the discounted cash flow method, we estimate fair value by calculating the present value of projected cash flows over a discrete period plus a terminal value based on normalized future cash flows.

Cash flow projections: Derived from estimates developed from our long-range plan, informed by industry trends — including wireline-specific factors — competitive landscape, product lifecycles, operational initiatives, and capital allocation strategies. These projections consider recent historical results and are consistent with our short-term financial forecasts and long-term business strategies.

Discount rate: Determined using a weighted average cost of capital, reflecting market participant assumptions for cost of equity and after-tax cost of debt, and incorporating risks inherent in the projections.

Terminal value: Represents expected normalized cash flows beyond the discrete projection period.

Uncertainty: Actual cash flows may differ significantly from projections due to inherent uncertainties.

Market Approach

Under the market approach, we estimate fair value of a reporting unit based upon market multiples applied to the reporting unit’s revenue and EBITDA, adjusted for an appropriate control premium based on recent market transactions.

Market multiples: Derived using publicly traded companies whose services and operating characteristics are comparable to ours.

Revenue and EBITDA: Derived using actual results and estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain strategic initiatives.

Weighting: Revenue and EBITDA multiples are weighted based on the characteristics of each reporting unit.

Control premium: Our implied control premium is a factor used to evaluate our fair value assessment and is evaluated for reasonableness, as described in the "Reconciliation" bullet below.

Our development of fair value estimates under both the discounted cash flow method and the market approach method are subject to inherent uncertainties and rely on assumptions about industry trends, competitive conditions, product lifecycles, and capital allocation.

Reconciliation: Estimated fair values are reconciled to our market capitalization to ensure reasonableness compared to market transactions.

Sensitivity and Risk Factors

Changes in assumptions used in the discounted cash flow method or market approach — such as asset and liability allocations — can materially affect fair value estimates, and actual results could vary significantly from our estimates and assumptions.

We perform sensitivity analyses using a range of discount rates and EBITDA multiples and believe our methods and assumptions are reasonable. However, any changes to these inputs can significantly impact whether impairment charges are required and the magnitude of those charges.

For additional information on our goodwill balances by segment and results of our impairment analyses, see Note 3 — Goodwill and Intangible Assets in Item 8.

Table of Contents
Pension and Post-retirement Benefits

We sponsor a noncontributory qualified defined benefit pension plan (the “Combined Pension Plan”), and several non-qualified pension plans for certain eligible highly compensated employees. Non-qualified plans are excluded from the disclosures below due to their immaterial impact on consolidated results. We also provide post-retirement health care and life insurance benefits to certain eligible retirees. See Note 11 — Employee Benefits in Item 8 for detailed plan descriptions, funding status, and investment strategies.

Our obligations are based on actuarial valuations requiring significant judgment and assumptions, including discount rate, mortality rates, and expected rate of return on plan assets. We consider these estimates critical because they involve complex actuarial models and significant judgment, and small changes can materially impact our financial condition and results of operations.

Key Assumptions

In computing our pension and post-retirement health care and life insurance benefit obligations, our most significant assumptions are the discount rate and mortality rates. In computing our periodic pension expense, our most significant assumptions are the discount rate and the expected rate of return on plan assets. In computing our post-retirement benefit expense, our most significant assumption is the discount rate.

Discount rate: The discount rate reflects the rate at which obligations could be settled at year-end, determined based on a cash flow matching analysis using hypothetical yield curves from high-quality U.S. corporate bonds and projected benefit payments. This process ensures a uniform rate that produces the same present value of the estimated future benefit payments as is generated by discounting each year’s benefit payments by spot rates derived from yields on the 60th–90th percentile of high-quality bonds.

Mortality rates: Mortality assumptions help predict the expected life of plan participants and are based on published tables from the Society of Actuaries (“SOA”), which update life expectancy projections for North America. We adopt new tables immediately upon release. No updates were issued in 2025, 2024, or 2023.

Expected rate of return: The expected return on plan assets is the long-term return we anticipate earning on the plans’ assets, net of administrative expenses. The rate is determined based on the strategic allocation of plan assets and long-term risk and return forecasts for each asset class. These forecasts are primarily derived from third-party investment management organizations, to which we add a factor of 50 basis points to reflect the benefit we expect to result from our active management of the assets. The rate is reviewed annually by management and our Board of Directors and adjusted as needed for market or investment strategy changes.

These assumptions are based on future events and are inherently uncertain, actual results may differ materially from estimates. Management monitors these assumptions regularly and updates them based on market conditions, plan experience, and other relevant factors.

Actuarial Losses and Gains

Actuarial gains and losses arise when actual experience differs from these assumptions or when assumptions are updated. These gains and losses are recorded in Other Comprehensive Income and amortized into earnings over time.

As of January 1, 2025, the Combined Pension Plan net actuarial loss balance was $1.4 billion with 65% subject to amortization over an average remaining service period of 9 years and 35% indefinitely deferred. As of January 1, 2025 the post-retirement benefit plans net actuarial gain balance was $404 million with 75% subject to amortization and 25% indefinitely deferred.

As of January 1, 2024 the Combined Pension Plan net actuarial loss balance was $1.4 billion with 64% subject to amortization over an average remaining service period of 13 years and 36% indefinitely deferred. As of January 1, 2024 the post-retirement benefit plans net actuarial gain balance was $337 million with 75% subject to amortization and 25% indefinitely deferred.

61

Table of Contents
As of the January 1, 2023 the Combined Pension Plan net actuarial loss balance of $1.4 billion, 62% was subject to amortization over an average remaining service period of 14 years and 38% indefinitely deferred during 2023. As of January 1, 2023 the post-retirement benefit plans net actuarial gain balance was $371 million with 56% subject to amortization and 44% indefinitely deferred.

Sensitivity Analysis

Changes in any of the assumptions used could significantly affect benefit obligations and expenses. The following table illustrates the estimated impact on benefit obligations assuming a hypothetical one percentage point change in the discount rate.

Percentage point change
Increase/(decrease) in Benefit Obligation
as of December 31, 2025
 (Dollars in millions)
Combined Pension Plan discount rate%$(316)
(1)%362 
Post-retirement benefit plans discount rate%(125)
(1)%125 

Similarly, changes in mortality assumptions or asset return expectations could significantly affect net periodic benefit cost and other comprehensive income. Because these assumptions are inherently uncertain and based on future events, actual results may differ materially from estimates.

Loss Contingencies

We are involved in several potentially material legal proceedings, as described in Note 17 — Commitments, Contingencies and Other Items in Item 8. Accounting for these matters requires significant judgment due to inherent uncertainty, complex legal interpretations, and evolving circumstances. We recognize an expense when a loss is probable and reasonably estimable. Determining whether a loss is probable and reasonably estimable involves significant judgment and assumptions about future events. These assumptions include legal interpretations, regulatory developments, and estimates of potential exposure. Actual outcomes may differ from these estimates, and such differences could materially affect our consolidated financial statements. Changes in assumptions or new developments could significantly increase or decrease earnings.

We evaluate these and other pending or threatened tax and legal matters on a quarterly basis.

Income Taxes

Given the significant judgment, inherent complexity, uncertainty of outcomes, varying internal and external factors, and overall potential to materially impact our financial results, we consider various aspects related to income taxes to be critical accounting estimates.

Uncertain Tax Positions

We apply the “more-likely-than-not” threshold when determining uncertain tax positions. This involves significant uncertainty because it requires management to apply judgment and make assumptions when estimating exposures related to various tax positions. We do not recognize any portion of an uncertain tax position if, in our judgment, the position has less than a 50% likelihood of being sustained. The validity of any tax position is ultimately a matter of tax law; the body of statutory, regulatory, and interpretive guidance on the application of the law is complex and often ambiguous, particularly in certain non-U.S. jurisdictions in which we operate. As such, our judgments may not be upheld, which could materially affect our consolidated financial statements. Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be adverse to Lumen and exceed the amount reserved. We evaluate these tax matters on a quarterly basis.

62

Table of Contents
Deferred Taxes

Our provision for income taxes includes amounts for current and deferred tax consequences. Deferred tax assets and liabilities reflect future tax effects of:

tax credit carryforwards;

differences between financial statement carrying values of assets and liabilities and tax basis of those assets and liabilities; and

NOLs and other tax attribute carryforwards.

Deferred taxes are computed using enacted tax rates expected to apply in the year in which the temporary differences are expected to affect taxable income. Changes in tax rates impacting deferred income tax assets and liabilities are recognized in earnings in the period of enactment.

The measurement of deferred taxes requires significant judgment related to the realization of tax basis. We evaluate whether tax positions taken in filed returns are more likely than not to be sustained upon audit. Determining applicable tax rates and timing of reversals involves judgment about future income apportionment among jurisdictions. Changes in our practices or these judgments could materially affect our financial condition and results of operations.

Valuation Allowances

We establish valuation allowances when it is more likely than not that some or all deferred tax assets will not be realized. This assessment considers recent pre-tax earnings, forecasts of future earnings, and the timing and nature of deductions and benefits, all of which involve the exercise of significant judgment. We review valuation allowances quarterly and adjust as needed for changes in tax law, interactions with taxing authorities, developments in case law, or other relevant factors.

As of December 31, 2025, we had a valuation allowance of $328 million, primarily related to state NOLs expected to expire unused. Future changes in earnings forecasts or the nature and estimated timing of future deductions and benefits may require adjustments to valuation allowances, which could materially impact our financial condition or results of operations.

We evaluate tax matters on a quarterly basis; see Note 15 — Income Taxes in Item 8 for additional details.

Table of Contents
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of December 31, 2025, we are exposed to market risk primarily from changes in interest rates on our variable-rate long-term debt obligations and from fluctuations in certain foreign currencies.

Interest Rate Risk

Our management periodically reviews our exposure to interest rate fluctuations and implements strategies to manage this risk. From time to time, we have used derivative instruments to convert variable interest rates to fixed rates. We maintain policies and procedures governing risk assessment, approval, reporting, and monitoring of derivative activities. As of December 31, 2025, we did not hold or issue derivative financial instruments for trading or speculative purposes.

As of December 31, 2025, we had approximately $5.9 billion aggregate principal amount of debt bearing unhedged floating interest rates based on the secured overnight financing rate ("SOFR"). A hypothetical increase of 100 basis points in SOFR relating to our unhedged floating rate debt would, among other things, decrease our annual pre-tax earnings by approximately $59 million.

Foreign Currency Risk

We conduct a small portion of our business in currencies other than the U.S. dollar, the currency in which our consolidated financial statements are reported. Prior to the November 1, 2023 divestiture of our EMEA business, certain former European subsidiaries used local currencies as their functional currency. Although we continue to evaluate strategies to mitigate risks related to fluctuations in currency exchange rates, we expect to continue recognizing gains or losses from international transactions. Accordingly, changes in foreign currency rates relative to the U.S. dollar could positively or negatively impact our operating results.

ITEM 8. CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors
Lumen Technologies, Inc.:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Lumen Technologies, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive (loss) income, cash flows, and stockholders’ (deficit) equity for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 20, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Testing of revenue
As discussed in Note 4 to the consolidated financial statements, the Company recorded $12.4 billion of operating revenues for the year ended December 31, 2025. The processing and recording of revenue are reliant upon multiple information technology (IT) systems.

We identified the evaluation of the sufficiency of audit evidence over revenue as a critical audit matter. Complex auditor judgment was required in evaluating the sufficiency of audit evidence over revenue due to the large volume of data and the number and complexity of the revenue accounting systems. Specialized skills and knowledge were needed to test the IT systems used for the processing and recording of revenue.
65

Table of Contents

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over the processing and recording of revenue, including the IT systems tested. We evaluated the design and tested the operating effectiveness of certain internal controls related to the processing and recording of revenue. This included manual and automated controls over the IT systems used for the processing and recording of revenue. For a selection of transactions, we compared the amount of revenue recorded to a combination of Company internal data, executed contracts, and other relevant third-party data. In addition, we involved IT professionals with specialized skills and knowledge who assisted in the design and performance of audit procedures related to certain IT systems used by the Company for the processing and recording of revenue. We evaluated the sufficiency of audit evidence obtained by assessing the results of procedures performed, including the relevance and reliability of evidence obtained.

Sufficiency of audit evidence over the implementation of enterprise resource planning system
The Company implemented the first phase of a new enterprise resource planning system (the ERP implementation) during the fourth quarter of 2025. The ERP implementation impacted a high volume of transactions, substantially all financial statement account balances, and certain disclosures.

We identified the evaluation of the sufficiency of audit evidence over the ERP implementation as a critical audit matter. Complex auditor judgment and the involvement of information technology (IT) professionals with specialized skills and knowledge were required to evaluate general IT controls and IT application controls of certain IT applications.

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over the ERP implementation. We involved IT professionals with specialized skills and knowledge, who assisted in:
obtaining an understanding of the relevant IT applications
evaluating the design and testing the operating effectiveness of certain general IT controls, including controls related to program development, change management, and logical access
evaluating the design and testing the operating effectiveness of certain IT application controls, including inspecting and evaluating configurations and interfaces.
We evaluated the sufficiency of audit evidence obtained by assessing the results of procedures performed, including the appropriateness of the nature and extent of the audit effort.

We have audited Lumen Technologies, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive (loss) income, cash flows, and stockholders’ (deficit) equity, for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated February 20, 2026 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

References in the Notes to "Lumen Technologies" or "Lumen," "we," "us," the "Company," and "our" refer to Lumen Technologies, Inc. and its consolidated subsidiaries, unless the context otherwise requires.

Note 1 — Background and Summary of Significant Accounting Policies

General

We are a leading digital networking services company, empowering enterprise businesses to fuel growth in a multi-cloud, AI-first marketplace by connecting people, data, and applications quickly, securely, and effortlessly. We are unleashing the world's digital potential by providing a broad array of integrated products and services to our domestic and global Business customers and our domestic Mass Markets customers. We operate one of the world’s most interconnected communications networks. Our platform empowers our customers to swiftly adjust digital programs to meet immediate demands, create efficiencies, accelerate market access, and reduce costs, which allows our customers to rapidly evolve their IT programs to address dynamic changes. Our specific products and services are detailed in Note 4 — Revenue Recognition.

Basis of Presentation

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated.

To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows:

income attributable to noncontrolling interests in other income (expense), net;

equity attributable to noncontrolling interests in common stock; and

cash flows attributable to noncontrolling interests in other, net financing activities.

As of December 31, 2025, we no longer have any noncontrolling interests. We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting for 2024 and 2023. See Note 16 — Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses, or net loss for any period.

Operating Expenses

Our current definitions of operating expenses are as follows:

Cost of services and products (exclusive of depreciation and amortization): Expenses incurred in providing products and services to our customers. These expenses include:

employee-related expenses directly attributable to operating and maintaining our network (e.g., salaries, wages, benefits, and professional fees);

network and facilities expenses (e.g., third-party telecommunications expenses we incur for using other carriers' networks to provide services to our customers);

rents and utilities expenses;

equipment sales expenses (e.g., modem expenses); and

other expenses directly related to our operations.
74

Table of Contents

Selling, general and administrative expenses: Corporate overhead and other operating expenses. These expenses include:

employee-related expenses directly attributable to selling products or services and employee-related expenses for administrative functions (e.g., salaries, wages, internal commissions, benefits and professional fees);

marketing and advertising;

property and other operating taxes and fees;

external commissions;

legal expenses associated with general matters;

bad debt expense; and

other selling, general, and administrative expenses.

These expense classifications may not be comparable to those of other companies.

Summary of Significant Accounting Policies

Use of Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and require management to make estimates and assumptions that affect reported amounts of assets, liabilities, equity, revenue, expenses, and cash flows and related disclosures. These estimates are based on information available at the time, including historical and forward-looking factors, that we believe are reasonable; however, these estimates may differ materially from actual results.

We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 15 — Income Taxes and Note 17 — Commitments, Contingencies and Other Items for additional information.

For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third-party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.

For matters related to income taxes, if we determine the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. We do not recognize any portion of an uncertain tax position if the position has less than a 50% likelihood of being sustained. We recognize interest on the amount of unrecognized benefit from uncertain tax positions.

Assets Held for Sale

Assets and related liabilities are classified as held for sale when:

management commits to a plan to sell the assets;

the assets are available for immediate sale;

an active program to locate a buyer is initiated; and

the sale is probable within one year.

75

Table of Contents
Assets and related liabilities held for sale are presented separately at the lower of (i) carrying amount or (ii) fair value less costs to sell. If the carrying amount exceeds fair value less cost to sell, a loss is recognized. Depreciation and amortization cease once assets are classified as held for sale. Assets classified as held for sale are remeasured each reporting period to ensure they are stated at the lower of (i) carrying amount or (ii) fair value less costs to sell.

Unless otherwise specified, the amounts and information presented in the notes do not include assets and liabilities that were classified as held for sale. See Note 2 — Divestitures for details on our recently completed divestitures.

Revenue Recognition

We recognize revenue primarily from contracts with customers for communications and related services in accordance with Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" (“ASC 606”). Revenue is measured based on the consideration we expect to receive and is recognized when control of goods or services transfers to the customer. We also earn revenue from leasing arrangements (e.g., fiber capacity and conduit leases and colocation agreements) and governmental subsidies, which are outside the scope of ASC 606.

Under ASC 606, revenue is recognized using the following five-step model:

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when, or as, we satisfy a performance obligation.

Service and Equipment Revenue

We provide a broad range of communications services to business and residential customers — including global, enterprise, wholesale, government, and small and medium business customers. Certain contracts include equipment sales, which are not significant to our operations. We recognize revenue for services when we provide the applicable service or when control of a product is transferred.

For arrangements using third-party vendors, we assess whether we act as a principal or agent to determine whether revenue is reported on a gross or net basis.

Performance Obligations

Customer contracts are evaluated to determine whether the performance obligations are separable. If the performance obligations are deemed separable and separate earnings processes exist, the transaction price is allocated to each performance obligation based on its relative standalone selling price. The revenue associated with each performance obligation is then recognized as when, or as, the performance obligation is satisfied.

Deferred Revenue and Fees

Payments received in advance — such as design, planning, engineering, activation, or installation fees — are deferred unless they represent separate performance obligations. When these payments are not separate obligations, we recognize them over the contract term or estimated useful life, typically one to five years, based on historical experience. Termination fees or other charges negotiated with new contracts are also deferred and recognized over the new contract term.

76

Table of Contents
Billing Practices

For access services, we generally bill fixed monthly charges one month in advance to customers and recognize revenue as service is provided over the contract term in alignment with the customer's receipt of service. For usage and other ancillary services, we generally bill in arrears and recognize revenue as usage or delivery occurs. In most cases, the amount invoiced for our service offerings constitutes the price that would be billed on a standalone basis.

Customer payments are made based on billing schedules included in our customer contracts, which is typically on a monthly basis.

Contract Costs

We defer (or capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 47 months for Mass Markets customers and 34 months for Business customers. These deferred costs are periodically monitored to reflect any significant change in assumptions.

Contract Modifications

In certain cases, customers may be permitted to modify their contracts. We evaluate the change in scope or price to identify whether the modification should be treated as a separate contract, as a termination of the existing contract and creation of a new contract, or as a change to the existing contract.

Indefeasible Rights of Use and Leases

We periodically sell transmission capacity on our network through indefeasible rights of use (“IRU”s), which grant the exclusive right to use a specified amount of capacity or fiber for a typical term of 20 years. Cash consideration received on transfers of transmission capacity is recognized as ASC 606 revenue, adjusted for time value of money and recognized ratably over the term. Cash consideration received on transfers of dark fiber is treated as non-ASC 606 lease revenue, which we also recognized ratably over the lease term. We treat contemporaneous exchanges of transmission capacity assets as non-revenue generating activities and therefore do not recognize revenue for these exchanges.

Service Level Commitments

We have service level commitments pursuant to contracts with certain of our customers. To the extent that we determine that such service levels were not achieved or may not have been achieved, we estimate the amount of credits to be issued and record a corresponding reduction to revenue in the period that the service level commitment was not met or may not be met.

See Note 4 — Revenue Recognition for additional information.

Advertising Costs

Costs related to advertising are expensed as incurred and recorded as selling, general and administrative expenses in our consolidated statements of operations. Our advertising expenses were:

Legal Costs

In the normal course of our business, we incur costs to hire and retain external legal counsel to advise us on finance, regulatory, litigation, and other matters. Subject to certain exceptions, we expense these costs as the related services are received.

77

Table of Contents
Income Taxes

We file a consolidated federal income tax return with our eligible subsidiaries. The provision for income taxes reflects taxes currently payable, tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to tax attributes carryforwards, including NOL carryforwards and tax credit carryforwards, and differences between the financial statement carrying value of assets and liabilities and the tax basis of those assets and liabilities. Deferred taxes are computed using enacted tax rates expected to apply in the year in which the differences are expected to affect taxable income. The effect on deferred income tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date.

We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain or adjust each valuation allowance on our deferred tax assets. See Note 15 — Income Taxes for additional information.

Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments that are readily convertible into cash and are not subject to significant risk from fluctuations in interest rates. As a result, the value at which cash and cash equivalents are reported in our consolidated financial statements approximates their fair value. In evaluating investments for classification as cash equivalents, we require that individual securities have original maturities of ninety days or less and that individual investment funds have dollar-weighted average maturities of ninety days or less. To preserve capital and maintain liquidity, we invest with financial institutions we deem to be of sound financial condition and in high quality and relatively risk-free investment products. Our cash investment policy limits the concentration of investments with specific financial institutions or among certain products and includes criteria related to credit worthiness of any particular financial institution.

Book overdrafts occur when we have issued checks but they have not yet been presented to our controlled disbursement bank accounts for payment. Disbursement bank accounts allow us to delay funding of issued checks until the checks are presented for payment. Until the issued checks are presented for payment, the book overdrafts are included in accounts payable on our consolidated balance sheets. This activity is included in the operating activities section in our consolidated statements of cash flows.

Restricted Cash

Restricted cash consists primarily of cash and investments that collateralize our outstanding letters of credit and certain performance and operating obligations. Restricted cash is recorded as current or non-current assets in the consolidated balance sheets depending on the duration of the restriction and the purpose for which the restriction exists.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recognized based upon the amount due from customers for the services provided or at cost for purchased and other receivables, less an allowance for credit losses. We use a loss rate method to estimate our allowance for credit losses. For more information on our methodology for estimating our allowance for credit losses, see Note 6 — Credit Losses on Financial Instruments.

We generally consider our accounts past due if they are outstanding over 30 days. Our past due accounts are written off against our allowance for credit losses and any recoveries are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable net of the allowance for credit losses approximates fair value. Accounts receivable balances acquired in a business combination are recorded at fair value for all balances receivable at the acquisition date and at the invoiced amount for those amounts invoiced after the acquisition date.

78

Table of Contents
Property, Plant and Equipment

Purchased and constructed property, plant, and equipment are recorded at cost and assets acquired through business combinations are recorded at their estimated fair value as of the acquisition date. In both instances we include the estimated value of any associated legally or contractually required retirement obligations.

Expenditures for maintenance and repairs are expensed as incurred. Supplies used internally are carried at average cost, except for significant individual items which are carried at actual cost.

Depreciation Methods

Prior to January 1, 2024: Most assets were depreciated using the straight-line group method. Under this approach, assets with similar characteristics and useful lives were pooled together and depreciated over the group’s average remaining useful life. When assets were sold or retired in the normal course of business, their cost was removed from both the asset and accumulated depreciation accounts, with no gain or loss recognized.

Effective January 1, 2024: We re-established all of our assets individually, including accumulated depreciation, and transitioned to depreciating all assets individually using the straight-line method over each asset’s estimated useful life. When assets are sold in the normal course of business, a gain or loss is recognized in our consolidated statements of operations.

Leasehold Improvements and Capital Projects

Leasehold improvements are amortized over the shorter of the assets’ useful lives or the expected lease term. During the construction phase of network and other internal-use capital projects, we capitalize related employee and interest costs.

Useful Lives

We perform annual internal reviews to evaluate the reasonableness of the depreciable lives for our property, plant and equipment. Our reviews utilize models that take into account actual usage, physical wear and tear, replacement history, and assumptions about technology evolution. Our remaining useful life assessments evaluate the possible loss in service value of assets that may precede the physical retirement. Assets shared among many customers may lose service value as those customers reduce their use of the asset. However, the asset is not retired until all customers no longer utilize the asset and we determine there is no alternative use for the asset.

Impairment Testing

We review long-lived tangible assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. For assessment purposes, long-lived assets are grouped with other assets and liabilities at the lowest identifiable level for which we generate cash flows independently of other groups of assets and liabilities. An impairment loss is recognized only if the carrying amount of the asset group is not recoverable and exceeds its estimated fair value. Recoverability of the asset group to be held and used is assessed by comparing the carrying amount of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. If the asset group's carrying value is not recoverable, we recognize an impairment charge for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

79

Table of Contents
Asset Retirement Obligations

We recognize asset retirement obligations (“ARO”s) for the legally or contractually required removal of certain property, plant, and equipment from leased properties, as well as for the disposal of hazardous materials in owned facilities. When an ARO is identified — typically at the time an asset is acquired — we record the fair value of the obligation as a liability and capitalize a corresponding amount as part of the asset’s cost. Our fair value estimates were determined using the discounted cash flow method. In subsequent periods, we increase the ARO liability for the passage of time (accretion expense) and adjust the liability and related asset for changes in the timing or amount of expected future cash flows. The capitalized amount is then amortized over the asset’s estimated remaining useful life. If a removal obligation is not legally binding, we expense the related removal costs as incurred, rather than capitalizing them.

Goodwill and Intangible Assets

Intangible assets acquired in business combinations — including goodwill, customer relationships, capitalized software, trademarks, and trade names — are recorded at estimated fair value at the acquisition date. Other intangible assets not arising from business combinations are initially recorded at cost.

We are required to reassign goodwill to reporting units whenever reorganizations of our internal reporting structure change the composition of our reporting units. Goodwill is reassigned to the reporting units using a relative fair value approach. As our remaining goodwill was fully impaired or reclassified as held for sale as of December 31, 2025, no further reassignment is required as the goodwill balance has been reduced to zero. When the fair value of a reporting unit is available, we allocate goodwill based on the relative fair value of the reporting units. When fair value is not available, we utilize an alternative allocation methodology that we believe represents a reasonable approximation of the fair value of the operations being reorganized.

Amortization

Intangible assets without legal, regulatory, contractual, or other limiting factors are classified as indefinite-lived and are not amortized. For finite-lived intangible assets, we amortize using the straight-line method over the following estimated lives:

Customer relationships: 7 - 14 years, depending on customer type

Capitalized software: 3 - 7 years

Other intangible assets: 9 - 20 years

Internal Use Software

Internally used software, whether purchased or developed by us, is capitalized and amortized using the straight-line method over its estimated useful life. We capitalized costs of employees devoted to software development and external direct costs for materials and services. Costs are expensed until the project reaches the development stage. Subsequent additions, modifications, or upgrades are capitalized only if they add new functionality. Software maintenance, data conversion, and training costs are expensed as incurred. We review the remaining economic lives of our capitalized software annually. Capitalized software is included in other intangible assets, net, in our consolidated balance sheets.

Impairment Testing

Finite-lived intangible assets are evaluated for impairment when triggering events or changes in circumstances occur. If fair value is less than the carrying amount, we record an impairment charge for the difference.

We test goodwill for impairment annually as of October 31, or more frequently if events suggest a reporting unit’s fair value may fall below its carrying value. If the carrying value of a reporting unit exceeds its fair value of equity, we write-down goodwill. Because reporting units are not separate legal entities with full financial statements, we determine equity carrying value and future cash flows during each impairment assessment we perform on a reporting unit. This involves allocating assets, liabilities, and cash flows to reporting units using reasonable, consistent methodologies. This process requires significant estimates, judgments, and assumptions.

For more information, see Note 3 — Goodwill and Intangible Assets.

Pension and Post-Retirement Benefits

We recognize the funded status of our defined benefit and post-retirement plans as an asset or a liability on our consolidated balance sheets. Each year's actuarial gains or losses are a component of our other comprehensive income (loss), which is then included in our accumulated other comprehensive loss on our consolidated balance sheets. Pension and post-retirement benefit expenses are recognized over the period in which the employee renders service and becomes eligible to receive benefits. We make significant assumptions (including the discount rate, expected rate of return on plan assets, mortality and health care trend rates) in computing the pension and post-retirement benefits expense and obligations. See Note 11 — Employee Benefits for additional information.

Foreign Currency

Local currencies of our foreign subsidiaries are the functional currencies for financial reporting purposes except for certain foreign subsidiaries. For operations with functional currencies other than the U.S. dollar, assets and liabilities are translated at period-end exchange rates, while revenue, expenses and cash flows use average monthly rates. Foreign currency translation gains and losses are recorded in accumulated other comprehensive loss in stockholders' (deficit) equity and in our consolidated statements of comprehensive (loss) income.

Before the November 1, 2023 sale of our EMEA business, many of our non-United States subsidiaries used the British pound or Euro as their functional currency, both of which fluctuated significantly against the U.S. dollar during the periods covered in this report when we operated the divested business. Prior to the divestiture, most investments in foreign subsidiaries were considered long-term. We continue to have immaterial operations transacted in foreign currencies. Foreign currency transaction gains and losses, including those not deemed long-term, are reported in other income (expense), net on our consolidated statements of operations.

For additional details on the sale of our EMEA business, see Note 2 — Divestitures.

Common Stock

On December 18, 2024, we amended our articles of incorporation to eliminate the par value of our common stock (which was, prior to such amendment, $1.00 per share) as approved by our shareholders at our 2024 annual shareholders meeting. We recognized the change by reclassifying the balance in Additional paid-in capital to Common stock on our consolidated balance sheet as of December 18, 2024. All changes in capitalization previously recognized as Additional paid-in capital will hereinafter be recognized in Common stock. This change had no other impact on our consolidated financial statements.

As of December 31, 2025, we had 24 million shares authorized for future issuance under our equity incentive plans.

Preferred Stock

Holders of outstanding Lumen Technologies preferred stock are entitled to receive cumulative dividends, receive preferential distributions equal to $25 per share plus unpaid dividends upon Lumen's liquidation and vote as a single class with the holders of common stock.

Section 382 Rights Agreement

We maintain a Section 382 Rights Agreement to protect our U.S. federal net operating loss carryforwards ("NOLs") from certain Internal Revenue Code Section 382 limitations. Under the agreement, one preferred stock purchase right was distributed for each share of our outstanding common stock as of the close of business on February 25, 2019, and those rights currently trade in tandem with the common stock until they expire or detach under the agreement. This agreement was designed to deter trading that would result in a change of control (as defined in Internal Revenue Code Section 382), and therefore protect our ability to use our historical federal NOLs in the future. The agreement is scheduled to lapse in late 2026.

Dividends

The declaration and payment of dividends is at the discretion of our Board of Directors. We do not currently pay a dividend on our common stock.

EMEA Business

On November 1, 2023, affiliates of Level 3 Parent, LLC, sold Lumen's operations in Europe, the Middle East and Africa ("EMEA") to Colt Technology Services Group Limited, a portfolio company of Fidelity Investments, for pre-tax cash proceeds of $1.7 billion after certain closing adjustments and transaction costs. This consideration is further subject to other post-closing adjustments and indemnities set forth in the purchase agreement, as amended and supplemented to date. In connection with the sale, we entered into a transition services agreement under which we provide the purchaser various support services. In addition, Lumen and the purchaser entered into commercial agreements whereby they provide each other various network and other commercial services.

The classification of the EMEA business as held for sale was considered an event or change in circumstance which requires an assessment of the goodwill of the disposal group for impairment each reporting period until disposal. We performed a pre-classification and post-classification goodwill impairment test of the disposal group as described further in Note 3 — Goodwill and Intangible Assets. As a result of our impairment tests, we determined the EMEA business disposal group was impaired, resulting in a non-cash, non-tax-deductible goodwill impairment charge of $43 million in the fourth quarter of 2022. We evaluated the recoverability of the carrying value of the assets and liabilities held for sale relative to the agreed upon sales price, adjusted for costs to sell, and recorded an estimated loss on disposal of $660 million during the year ended December 31, 2022 in the consolidated statement of operations and a valuation allowance included in assets held for sale on the consolidated balance sheet as of December 31, 2022. For the year ended December 31, 2023, we recorded a $102 million net loss on disposal associated with the sale of our EMEA business. This loss is reflected as operating expense within the consolidated statements of operations.

The EMEA business was included in our continuing operations and classified as assets and liabilities held for sale on our consolidated balance sheets through the closing of the transaction on November 1, 2023. As a result of closing the transaction, we derecognized net assets of $2.1 billion, primarily made up of (i) property, plant and equipment, net of accumulated depreciation, of $2.0 billion and (ii) customer relationships and other intangible assets, net of accumulated amortization of $107 million. In addition, we reclassified $382 million of realized loss on foreign currency translation, net of tax, with an offset to the valuation allowance and loss on sale of the EMEA business.

Mass Markets Fiber-to-the-Home Business

On May 21, 2025, we entered into a definitive agreement to sell our Mass Markets Fiber-to-the-Home business in 11 states (the "Territory") to AT&T for $5.75 billion in cash, subject to working capital and other negotiated purchase price adjustments.

The actual amount of our net after-tax proceeds from this divestiture could vary substantially from the amounts we currently estimate, including if there are changes in other assumptions that impact our estimates.

As of December 31, 2025 in the accompanying consolidated balance sheet, the assets and liabilities of the disposal group are classified as held for sale and measured at the lower of (i) the carrying value when we classified the disposal group as held for sale or (ii) the fair value of the disposal group, less costs to sell. Effective with the designation of the disposal group as held for sale on May 21, 2025, we suspended recording depreciation of property, plant and equipment while these assets are classified as held for sale. We estimate that we would have recorded an additional $104 million of depreciation for the year ended December 31, 2025 if the disposal group did not meet the held for sale criteria.

Under the terms of the purchase agreement related to the sale of the Mass Market Fiber-to-the-Home business in the Territory, Lumen agreed to grant the purchaser an indefeasible right to use (“IRU”) certain Lumen retained fiber assets following the closing of the transaction in order to service the transferred customer contracts. The value of these retained Lumen assets subject to the IRU is excluded from assets held for sale in the table below.

Subsequent Event

On February 2, 2026, we and certain of our affiliates completed the sale of our Mass Markets Fiber-to-the-Home business in 11 states to AT&T in exchange for pre-tax cash proceeds of approximately $5.75 billion, subject to working capital and other negotiated post-closing adjustments. In connection with the sale, Lumen has entered into a transition services agreement under which it will provide to the purchaser various support services and certain long-term agreements under which Lumen and the purchaser will provide to each other various network and other commercial services.

Treatment of Consolidated Operating Results of Divested Businesses

We do not believe the divestiture of the EMEA business or the recently completed divestiture of the Mass Markets Fiber-to-the-Home business represent a strategic shift for Lumen, and therefore do not qualify as discontinued operations. As a result, we continued to report our operating results for the EMEA business and the Mass Markets Fiber-to-the-Home business in our consolidated operating results through their respective disposal dates of November 1, 2023 and February 2, 2026.

______________________________________________________________________ 
(1)We recorded cumulative non-cash, non-tax-deductible goodwill impairment charges of $628 million during the year ended December 31, 2025.
(2)As of December 31, 2025, this amount excluded goodwill classified as held for sale of approximately $1.3 billion. See Note 2 — Divestitures.
(3)Certain capitalized software with a gross carrying value of $161 million and $352 million and trade names with a gross carrying value of $211 million and $153 million became fully amortized during 2024 and 2023, respectively, and were retired during the first quarter of 2025 and 2024, respectively.

As of December 31, 2025 and December 31, 2024, the gross carrying amount of goodwill and intangible assets was $13.4 billion and $15.4 billion, respectively, excluding the amounts classified as held for sale.

We are required to assess our goodwill and other indefinite-lived intangible assets for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. As of December 31, 2025, we had no indefinite-lived intangible assets and our remaining goodwill was classified as held for sale. As such, we did not perform any annual impairment assessment for the year ended December 31, 2025 and the only impairment testing performed on our goodwill for the year-ended December 31, 2025 was performed on April 30, 2025 due to a triggering event as described below. Our annual impairment assessment date for indefinite-lived intangible assets other than goodwill was historically December 31. We completed our qualitative assessment of our indefinite-lived intangible assets other than goodwill as of December 31, 2024 and 2023 and concluded it is more likely than not that our indefinite-lived intangible assets were not impaired; thus, no impairment charge for these assets was recorded in 2024 or 2023.

Our goodwill was historically derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired. We are required to write down the value of goodwill only when our assessment determines the carrying value of equity of any of our reporting units exceeds its fair value. Our annual impairment assessment date for goodwill was October 31, at which date we assessed our reporting units.

We report our results within two segments: Business and Mass Markets. See Note 16 — Segment Information for more information on these segments and the underlying sales channels. As of April 30, 2025, we had three reporting units for goodwill impairment testing, which were:

Mass Markets;

North America Business ("NA Business"); and

Asia Pacific ("APAC") region.

Prior to the divestiture of the EMEA business in November 2023, the EMEA region was also a reporting unit and was tested for impairment.

88

Table of Contents
Our reporting units are not discrete legal entities with discrete full financial statements. Our assets and liabilities are deployed in and relate to the operations of multiple reporting units. When we assess goodwill for impairment, we compare the estimated fair value of each reporting unit's equity to the carrying value of equity that we assign to the reporting unit. If the estimated fair value of the reporting unit is greater than the carrying value, we conclude that no impairment exists. If the estimated fair value of the reporting unit is less than the carrying value, we record a non-cash impairment charge equal to the excess amount. Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours.

Goodwill Impairment Analysis

2025 Goodwill Impairment Analysis

During the second quarter of 2025, we determined that the classification of the Mass Markets Fiber-to-the-Home business in the Territory as held for sale as described in Note 2 — Divestitures was considered an event or change in circumstance which required an assessment of our goodwill for impairment as of April 30, 2025. We performed a pre-classification goodwill impairment assessment, as of April 30, 2025, using the market approach to test for impairment prior to the classification of these assets as held for sale and to determine the fair value of our Mass Markets reporting unit for the assignment of goodwill held for sale. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry which supported a range of fair values derived from annualized revenue and earnings before interest, tax, depreciation and amortization ("EBITDA") multiples between 1.8x and 3.1x and 5.8x and 8.0x, respectively. We reconciled the estimated fair values of the reporting units to our market capitalization as of April 30, 2025 and concluded that the indicated control premium of approximately 42% was reasonable based on recent market transactions. We concluded no impairment existed at any of our reporting units as of our April 30, 2025 assessment date.

We also performed a post-classification goodwill impairment test using the market approach to evaluate whether the fair value of our reporting units that will remain following the divestiture exceeds the carrying value of the equity of such reporting units after classification of assets held for sale and concluded the indicated control premium of approximately 4% was reasonable based on recent market transactions. As a result of this analysis, we determined that the Mass Markets reporting unit was fully impaired, resulting in us recognizing a non-cash, non-tax-deductible goodwill impairment charge of $628 million during the quarter ended June 30, 2025.

The market approach we used in the quarter ended June 30, 2025 incorporated estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain strategic initiatives. In developing the market multiples applicable for each reporting unit, we considered observed trends of our industry participants. Our assessment included many factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairment.

Subsequent to this impairment analysis and as of December 31, 2025, our only remaining goodwill was classified as held for sale.

2024 Goodwill Impairment Analysis

As of October 31, 2024, we performed our annual impairment analysis of the goodwill in our Mass Markets reporting unit by using a qualitative assessment to determine whether it was more likely than not that the fair value of the reporting unit was less than its carrying value. Factors considered in the qualitative assessment included, among other things, macroeconomic conditions, industry and market conditions, financial performance of the reporting unit and other relevant entity and reporting unit considerations. We concluded the estimated fair value of our reporting unit was greater than our carrying value of equity as of our testing date. Therefore, we concluded no impairment existed as of our annual assessment date in the fourth quarter of 2024.

2023 Goodwill Impairment Analyses

During 2023, we recorded non-cash and non-tax-deductible goodwill impairment charges totaling $10.7 billion related to certain reporting units. In the second quarter of 2023, we determined circumstances existed indicating it was more likely than not that the carrying value of our reporting units exceeded their fair value, resulting in an impairment charge of $8.8 billion. An additional $1.9 billion was recorded as part of our annual goodwill impairment analysis of our three reporting units performed on October 31, 2023

Given the continued erosion in our market capitalization, both quantitative impairment analyses were performed using the market approach, which relied on company comparisons and analyst reports within the telecommunications industry to develop fair value ranges based on annualized revenue and EBITDA multiples. For each of our assessments, we used revenue and EBITDA multiples below these comparable market multiples. Estimated fair values were reconciled to market capitalization, and any implied control premium was determined to be reasonable based on recent market transactions at that time. Significant judgment was required in developing assumptions, and alternative interpretations could have resulted in different conclusions regarding the size of our impairments.

(1)    As of December 31, 2025, this amount excluded $13 million of customer receivables, net associated with the disposal group classified as held for sale.
(2)     As of December 31, 2025, this amount excluded $32 million of contract liabilities associated with the disposal group classified as held for sale.

Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation, and maintenance charges that are deferred and recognized over the actual or expected contract term, which typically ranges from one to five years depending on the service. Contract liabilities are included within Deferred revenue on our consolidated balance sheets. During the years ended December 31, 2025 and December 31, 2024, we recognized $478 million and $443 million, respectively, of revenue that was included in contract liabilities of $733 million and $698 million as of January 1, 2025 and 2024, respectively, including contract liabilities that were classified as held for sale.

Performance Obligations

As of December 31, 2025, we expect to recognize approximately $6.0 billion of revenue in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied. As of December 31, 2025, the transaction price related to unsatisfied performance obligation that are expected to be recognized in 2026, 2027, and thereafter was $2.8 billion, $1.6 billion and $1.6 billion, respectively.

These amounts exclude:

the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed (for example, uncommitted usage or non-recurring charges associated with professional or technical services to be completed);

contracts that are classified as leasing arrangements or government assistance that are not subject to ASC 606; and

the value of unsatisfied performance obligations for contracts which relate to the disposal group classified as held for sale.

(1)    The ending balance for the year ended December 31, 2025 excluded $24 million and $21 million of acquisition costs and fulfillment costs, respectively, associated with the disposal group classified as held for sale.

Acquisition costs include commission fees paid to employees as a result of obtaining contracts. Fulfillment costs include third-party and internal costs associated with the provision, installation and activation of services to customers, including labor and materials consumed for these activities.

We amortize deferred acquisition and fulfillment costs based on the transfer of services on a straight-line basis over the average contract life of approximately 47 months for Mass Markets customers and 34 months for Business customers. We include amortized fulfillment costs in Cost of services and products and amortized acquisition costs in Selling, general and administrative in our consolidated statements of operations. We include the amount of these deferred costs that are anticipated to be amortized in the next 12 months in Other current assets, net and the deferred costs expected to be amortized beyond the next 12 months in Other assets, net on our consolidated balance sheets. We assess deferred acquisition and fulfillment costs for impairment on a quarterly basis.

Governmental Funding

Lumen participates in various U.S. federal and state programs under which government support payments are received to offset costs associated with providing services in targeted locations such as unserved or underserved high-cost or rural areas, or for certain types of customers, including non-profit organizations, educational institutions and local governmental bodies. In certain instances, support payments are conditioned on specified infrastructure buildouts by milestone deadlines or provision of services at specified locations and speed requirements. Commitments may be made annually, on a multi-year basis ranging from one to 10 years or be on-going subject to periodic change or termination. Consistent with customary practice and as referenced in ASC 832 Government Assistance, Lumen applies a grant model of accounting by which it accounts for these transactions as non-ASC 606 revenue over the periods in which the costs for which the funding is intended to compensate are incurred. This non-ASC 606 revenue is included in operating revenue in our consolidated statements of operations. Corresponding receivables are recorded when services have been provided to the customers and costs incurred, but the cash has not been received. These amounts are included in our accounts receivable, less allowance in our consolidated balance sheets. Certain programs are subject to audits of compliance with program commitments and, subject to the outcomes of those assessments, Lumen may be required to reimburse the government entity for cash previously received, or, in some cases, pay a penalty. Lumen evaluates each program and establishes a liability under the principles of ASC 450 if it is probable support payments will be recaptured or a penalty will be imposed.

For both the years ended December 31, 2025 and 2024, Lumen recorded non-customer revenue of $67 million and $83 million, respectively, under government assistance programs, of which 28% and 18%, respectively, was associated with state universal service fund support programs.

The federal government has introduced several programs expand broadband access, including the Rural Digital Opportunity Fund (“RDOF”) program, an FCC initiative that provides federal financial support to fund broadband deployment in rural America. We were awarded RDOF funding in several of the states in which we operate and received payments for a period starting in 2022. We received approximately $17 million in annual RDOF Phase I support payments for the year ended December 31, 2023. In the third quarter of 2024, we relinquished rights to develop certain RDOF census blocks in four states, which resulted in a reduction of the anticipated RDOF Phase I support payments to approximately $16 million for the year ending December 31, 2024. In the second quarter of 2025, we voluntarily relinquished the remainder of our RDOF awards. As a result, we will no longer receive funding through the RDOF program and recognized a reduction to revenue of $46 million in our consolidated statements of operations in the second quarter of 2025. We also incurred fees of $49 million in connection therewith, which are reflected in our operating expenses within our consolidated statements of operations. In January 2026, we paid the $95 million of revenue and fees summarized above, along with an additional $4 million relating to our 2024 relinquishment as repayment of funds previously received and remittance of the fees incurred.

Lumen participates in two state sponsored programs for broadband deployment in unserved and underserved areas for which the states have state universal service funds sourced from fees levied on telecommunications providers and passed on to consumers. During the years ending December 31, 2025 and 2024, Lumen participated in these types of programs in the states of Nebraska and New Mexico.

Note 5 — Leases

We primarily lease various office facilities, colocation facilities, equipment and transmission capacity to or from third parties. Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheets; we recognize lease expense for these leases on a straight-line basis over the lease term.

We determine if an arrangement is a lease at inception and whether that lease meets the classification criteria of a finance or operating lease at the commencement date. Lease-related assets, or right-of-use assets, are recognized at the lease commencement date at amounts equal to the respective lease liabilities. Lease-related liabilities are recognized at the present value of the remaining contractual fixed lease payments, discounted using our incremental borrowing rates. As part of the present value calculation for the lease liabilities, we use an incremental borrowing rate as the rates implicit in the leases are not readily determinable. The incremental borrowing rates used for lease accounting are based on our unsecured rates, adjusted to approximate the rates at which we could borrow on a collateralized basis over a term similar to the recognized lease term. We apply the incremental borrowing rates to lease components using a portfolio approach based upon the length of the lease term and the reporting entity in which the lease resides. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.

Some of our lease arrangements contain lease components, non-lease components (including common-area maintenance costs) and executory costs (including real estate taxes and insurance costs). We generally account for each component separately based on the estimated standalone price of each component. For colocation leases, we account for the lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless we determine that we are reasonably certain of renewing the lease. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain to be exercised. Our lease agreements do not generally contain any material residual value guarantees or material restrictive covenants.

We lease various equipment, office facilities, retail outlets, switching facilities and other network sites or components from third parties. These leases, with few exceptions, provide for renewal options and rent escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The lease term for most leases includes the initial non-cancelable term plus any term under renewal options that we believe are reasonably assured.

Lessor

We lease various dark fiber and conduit, office facilities, colocation facilities, switching facilities, other network sites, and service equipment to third parties under operating leases. Lease and sublease revenue are included in operating revenue in the consolidated statements of operations. See "Revenue Recognition" in Note 1 — Background and Summary of Significant Accounting Policies.

For the years ended December 31, 2025, 2024, and 2023, our gross operating lease revenue was $1.1 billion, $1.0 billion and $1.0 billion, respectively, which represents 9%, 7%, and 7% of our operating revenue for the years ended December 31, 2025, 2024, and 2023.

Included in our operating lease revenue is sublease revenue of $23 million, $25 million, and $25 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Note 6 — Credit Losses on Financial Instruments

To assess our expected credit losses on financial instruments, we aggregate financial assets with similar risk characteristics to monitor their credit quality or deterioration over the life of such assets. We periodically monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change. We separately evaluate financial assets that do not share risk characteristics with other financial assets. Our financial assets measured at amortized cost primarily consist of accounts receivable.
99

Table of Contents

We use a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our review of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable.

If there is an unexpected deterioration of a customer's financial condition or an unexpected change in economic conditions, including macroeconomic events, we assess the need to adjust the allowance for credit losses. Any such resulting adjustments would affect earnings in the period that adjustments are made.

The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding our allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future, and we may use methodologies that differ from those used by other companies.

(1)Except for Lumen's Term Loan A and $1.375 billion of Level 3 Financing's 11.000% First Lien Notes due 2029, all of the debt listed in this table was issued in the first quarter of 2024 in exchange for previously-issued debt of Lumen or Level 3 Financing in connection with the TSA Transactions.
(2)Reflects approximately $66 million of term loan installment payments and paydowns made between the TSA Effective Date and December 31, 2024.

In evaluating the terms of the TSA Transactions, we determined that for certain of our creditors the new debt instruments were substantially different than pre-existing debt and therefore constituted a non-cash extinguishment of old debt for Lumen Technologies and Level 3 Financing of $744 million and $2.6 billion, respectively, and the establishment of new debt for which we recorded a $275 million gain on extinguishment in the first quarter of 2024. This new debt was recorded at fair value generating a reduction to debt of $492 million which was included in our aggregate Net (loss) gain on early retirement of debt of $348 million, recognized in Other income (expense), net in our consolidated statement of operations for the year ended December 31, 2024. The remaining creditors’ newly-issued debt was not substantially different under the terms of the TSA Transactions and was treated under modification accounting rules. In conjunction with the TSA Transactions, we paid $209 million in lender fees and $174 million in additional third-party costs. Of these amounts, we offset $157 million of lender fees against the gain on extinguishment and recorded $112 million in third-party costs to Selling, general and administrative expense in our consolidated statement of operations for the year ended December 31, 2024. In accordance with GAAP provisions for modification and extinguishment accounting, $52 million in lender fees and $62 million in third-party costs, respectively, were capitalized and will be amortized over the terms of the newly-issued indebtedness.

Interest on borrowings under the RCF/TLA Credit Agreement is payable at the end of each interest period at a rate equal to, at Lumen’s option:

Both of the Lumen Revolving Credit Facilities mature on June 1, 2028 (in each case subject to a springing maturity in certain circumstances). The Lumen TLA matures on June 1, 2028 and requires Lumen to make quarterly amortization payments of 1.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions.

As of December 31, 2025, no borrowings were outstanding under Lumen’s (i) Series A Revolving Credit Facility, with commitments of approximately $489 million, or (ii) Series B Revolving Credit Facility, with commitments of approximately $465 million.

The Lumen TLB requires Lumen to make quarterly amortization payments of 0.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions. Amounts outstanding under the Lumen TLB may be prepaid at any time without premium or penalty.

Lumen Former Facilities

In connection with entering into the RCF/TLA Credit Agreement, all revolving commitments under Lumen’s amended and restated credit agreement dated January 31, 2020 (the “Former Parent Facilities”) were terminated and all of the debt issued thereunder was repaid as of December 31, 2025.

Level 3 Credit Agreements

Credit Agreement dated March 22, 2024

On the TSA Effective Date, Level 3 Financing, as borrower, Level 3 Parent, LLC. the lenders party thereto and WTNA, as administrative agent and collateral agent, entered into the Original Level 3 Credit Agreement, providing for:

a secured term B-1 loan facility in the principal amount of approximately $1.2 billion maturing April 15, 2029; and

a secured term B-2 loan facility in the principal amount of approximately $1.2 billion maturing April 15, 2030.

Pursuant to the First Credit Facilities Transactions, Level 3 Financing refinanced all of the outstanding secured Term Loan B-1 facilities and secured Term Loan B-2 facilities under the Original Level 3 Credit Agreement under its new secured Term Loan B-3 facility. Pursuant to the Second Credit Facilities Transactions, Level 3 Financing refinanced all of the outstanding secured Term Loan B-3 facilities under the Existing Level 3 Credit Agreement under its new secured Term Loan B-4 facility.

As of December 31, 2025, Level 3 Financing had $2.4 billion of non-amortizing secured Term Loan B-4 outstanding under the term loan facility established by the Level 3 Credit Agreement.

Borrowings under the Term Loan B-4 facility will be, at Level 3 Financing’s option, either (i) the base rate (which is the highest of (x) the overnight federal funds rate, plus 0.50%, (y) the prime rate on such day, and (z) the one-month SOFR published on such date, plus 1.00%), plus an applicable margin, or (ii) one-, three- or six-month SOFR, plus an applicable margin. The applicable margin for SOFR loans under the Term Loan B-4 will be 3.25%. The Term Loan B-4 is subject to a SOFR floor of 0.00%.

Level 3 Financing may voluntarily prepay loans or reduce commitments under the Level 3 Credit Agreement, in whole or in part, subject to minimum amounts, with prior notice, but without premium or penalty (other than a 1.00% premium on any prepayment in connection with a repricing transaction prior to March 29, 2026). Level 3 Financing is required to prepay borrowings under the term loan facility with 100% of the net cash proceeds of certain asset sales and 100% of the net cash proceeds of certain debt issuances, in each case subject to certain exceptions.

Level 3 Former Facility

In connection with entering into the Original Level 3 Credit Agreement, all of the indebtedness issued under Level 3 Financing’s amended and restated credit agreement dated as of November 29, 2019 (the “Former Level 3 Facility”) was repaid as of December 31, 2025.

Senior Notes of Lumen and its Subsidiaries

The Company’s consolidated indebtedness related to the senior notes of Lumen and its subsidiaries as of December 31, 2025 included:

superpriority senior secured notes issued by Lumen;

first and second lien secured notes issued by Level 3 Financing; and

senior unsecured notes issued by Lumen, Level 3 Financing, Qwest, and Qwest Capital Funding, Inc.

All of these notes carry fixed interest rates and all principal is due on the notes’ respective maturity dates, which rates and maturity dates are summarized in the table above.

Except for a limited number of senior notes issued by Qwest Corporation, the issuer generally can redeem the notes, at its option, in whole or in part, (i) pursuant to a fixed schedule of pre-established redemption prices, (ii) pursuant to a “make whole” redemption price, or (iii) under certain other specified limited conditions.

Revolving Letters of Credit

We use various financial instruments in the normal course of business. These instruments include letters of credit, which are conditional commitments issued on our behalf in accordance with specified terms and conditions. Lumen may draw letters of credit under (i) an uncommitted $225 million revolving letter of credit facility and (ii) the Lumen Revolving Credit Facilities.

As of December 31, 2025, we had $234 million of undrawn letters of credit outstanding, (i) $232 million of which were issued under the Lumen Revolving Credit Facilities and (ii) $2 million of which were issued under a separate facility maintained by Lumen subsidiaries (the full amount of which is collateralized by cash that is reflected on our consolidated balance sheets as restricted cash within Other assets, net).

Certain Guarantees and Security Interests

Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement are unsecured, but certain of Lumen’s subsidiaries have provided an unconditional guarantee of payment of Lumen’s obligations (such entities, the “Lumen Guarantors”) and certain of such guarantees are secured by a lien on substantially all of the assets of the applicable Lumen Guarantors. Level 3 Parent, Level 3 Financing and certain of Level 3 Financing’s subsidiaries have provided an unconditional guarantee of payment of Lumen’s obligations under each of its Series A Revolving Credit Facility of up to $150 million and its Series B Revolving Credit Facility of up to $150 million, in each case secured by a lien on substantially all of their assets (such entities, the “Level 3 Collateral Guarantors”). The guarantee by the Level 3 Collateral Guarantors may be reduced or terminated under certain circumstances. Qwest Corporation and certain of its subsidiaries have provided an unsecured guarantee of collection of Lumen’s obligations under the Revolving Credit Facilities and Lumen TLA (such entities, the “Qwest Guarantors”).

Lumen’s obligations under the Superpriority Term Loan B Credit Agreement are unsecured. The term loans issued under this agreement are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement.

Level 3 Financing’s obligations under the Level 3 Credit Agreement are secured by a first priority lien on substantially all of its assets. In addition, the other Level 3 Collateral Guarantors have provided a guarantee of Level 3 Financing’s obligations under the Level 3 Credit Agreement secured by a lien on substantially all of their assets.

Table of Contents
Lumen’s superpriority secured senior notes are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement (subject, in certain cases, to receipt of necessary regulatory approvals). Level 3 Financing’s obligations under its first priority lien notes are secured by a first lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals), and are guaranteed by the other Level 3 Collateral Guarantors (or, for certain such guarantors, for certain notes, will be guaranteed upon the receipt of required regulatory approvals) on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement. Level 3 Financing’s obligations under its second lien notes are secured by a second lien on substantially all of its assets, and are guaranteed by the other Level 3 Collateral Guarantors on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement, except the lien securing such guarantees is a second lien.

Lumen's reimbursement obligations under its outstanding letters of credit are secured by guarantees issued by certain of its subsidiaries.

Level 3 Financing's obligations under its unsecured notes are guaranteed on an unsecured basis by the same affiliated entities that guarantee the Level 3 Credit Agreement and secured notes. The senior unsecured notes issued by Qwest Capital Funding, Inc. are guaranteed by its parent, Qwest Communications International Inc.

Covenants

Lumen

Under its Superpriority Revolving/Term Loan A Credit Agreement, Lumen may not permit:

its maximum total net leverage ratio to exceed 5.50 to 1.00 with respect to each fiscal quarter ending after December 31, 2024 and further stepping down to 5.25 to 1.00 with respect to each fiscal quarter ending after December 31, 2025; or

its interest coverage ratio as of the last day of any test period to be less than 2.00 to 1.00.

Lumen’s superpriority credit agreements and superpriority senior secured notes contain various representations and warranties and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on our ability to declare or pay dividends, repurchase stock, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, engage in transactions with our affiliates, dispose of assets and merge or consolidate with other persons.

Lumen’s senior unsecured notes were issued under four separate indentures. These indentures restrict Lumen’s ability to (i) incur, issue or create liens upon its property and (ii) consolidate with or merge into, or transfer or lease all or substantially all of its assets to, any other party.

Under certain circumstances in connection with a “change of control” of Lumen, Lumen will be required to make an offer to repurchase substantially all of these senior notes at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest.

Level 3 Financing

The Level 3 Credit Agreement and Level 3 Financing's first and second lien secured notes and unsecured notes contain various representations and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on their ability to declare or pay dividends, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, dispose of assets, and merge or consolidate with other persons. Also, under certain circumstances in connection with a “change of control” of Level 3 Parent or Level 3 Financing, Level 3 Financing will be required to make an offer to repurchase each series of its outstanding senior notes at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest.

Qwest Corporation and Qwest Capital Funding, Inc.

The senior notes of Qwest Corporation were issued under indentures dated April 15, 1990 and October 15, 1999. These indentures contain restrictions on the incurrence of liens and the consummation of certain transactions substantially similar to the above-described covenants in the indentures governing Lumen’s senior unsecured notes (but contain no mandatory repurchase provisions). The senior notes of Qwest Capital Funding, Inc. were issued under an indenture dated June 29, 1998 containing terms substantially similar to those set forth in Qwest Corporation's indentures.

Compliance

As of December 31, 2025, Lumen Technologies, Inc. believes it and its subsidiaries were in compliance with the provisions and financial covenants in their respective material debt agreements in all material respects.

Guarantees

Lumen does not guarantee the debt of any unaffiliated parties, but, as noted above, as of December 31, 2025, certain of its key subsidiaries have guaranteed on either a secured or unsecured basis (i) Lumen's debt outstanding under its superpriority credit agreements, its superpriority senior secured notes and unsecured senior notes issued by certain other subsidiaries and its $225 million letter of credit facility and (ii) the outstanding term loans, senior secured notes and senior unsecured notes issued by certain other subsidiaries. As further noted above, several of the subsidiaries guaranteeing these obligations have pledged substantially all of their assets to secure certain of their respective guarantees.

Subsequent Events

Senior Secured Notes

On January 9, 2026, Level 3 Financing, Inc. issued an additional $650 million aggregate principal amount of its 8.500% Senior Notes due 2036. Level 3 Financing used the net proceeds from this offering, to fund the repurchase of its outstanding Second Lien Notes.

During 2024, we initiated marketing of our Broomfield, Colorado office buildings to locate a buyer and have classified those buildings as held for sale, resulting in an impairment loss of $80 million. During the second quarter of 2023, we donated our Monroe, Louisiana campus and leased back a portion thereof. This donation resulted in a $101 million loss recognized for the year ended December 31, 2023.

As of December 31, 2025, we classified certain property, plant and equipment, net as held for sale and discontinued recording depreciation on the disposal group. See Note 2 — Divestitures.

We recorded depreciation expense of $1.7 billion, $1.9 billion and $1.9 billion for the years ended December 31, 2025, 2024 and 2023, respectively.

Asset Retirement Obligations

As of December 31, 2025 and 2024, our asset retirement obligations consisted primarily of estimated future costs of removing equipment from leased properties and estimated future costs of properly disposing of asbestos and other hazardous materials upon remodeling or demolishing buildings. Asset retirement obligations are included in other long-term liabilities on our consolidated balance sheets.

The changes in estimate referred to in the table above were offset against gross property, plant and equipment.

Note 10 — Severance

Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workloads due to reduced demand for certain services.

During April 2024, we further reduced our workforce by approximately 6% as a part of our efforts to change our workforce composition to reflect our ongoing transformation and cost reduction opportunities that align with our shapeshifting and focus on our strategic priorities. As a result of this plan, we incurred severance and related costs of approximately $103 million during the second quarter of 2024. We have not incurred, and do not expect to incur, any material impairment or exit costs related to either of these plans.

We report severance liabilities within accrued expenses and other liabilities - salaries and benefits in our consolidated balance sheets and report severance expenses in selling, general and administrative expenses in our consolidated statements of operations. As described in Note 16 — Segment Information, we do not allocate these severance expenses to our segments.

Changes in our accrued liabilities for severance expenses were as follows:

Note 11 — Employee Benefits

Pension, Post-Retirement, and Other Post-Employment Benefits

We sponsor various defined benefit pension plans (qualified and non-qualified) which, in the aggregate, cover a substantial portion of our employees. Pension benefits for participants of the Lumen Combined Pension Plan ("Combined Pension Plan") who are represented by a collective bargaining agreement are based on negotiated schedules. All other participants' pension benefits are based on each individual participant's years of service and compensation. We also maintain non-qualified pension plans for certain current and former highly compensated employees. We maintain post-retirement benefit plans that provide health care and life insurance benefits for certain eligible retirees. We also provide other post-employment benefits for certain eligible former employees. We use a December 31 measurement date for all our plans.

Pension Benefits

United States funding laws require a company with a pension shortfall to fund the annual cost of benefits earned in addition to a seven-year amortization of the shortfall. Our funding policy for our Combined Pension Plan is to make contributions with the objective of accumulating ample assets to pay all qualified pension benefits when due under the terms of the plan. The accounting unfunded status of the Combined Pension Plan was $559 million and $615 million as of December 31, 2025 and 2024, respectively.

We made no voluntary cash contributions to the trust for the Combined Pension Plan in 2025. In 2024, we made a voluntary cash contribution of $170 million to the trust for the Combined Pension Plan. We paid $4 million of benefits directly to participants of our non-qualified pension plans in both 2025 and 2024.

Benefits paid by the Combined Pension Plan are paid through a trust that holds all the Plan's assets. The amount of required contributions to the Combined Pension Plan in 2026 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. Based on current laws and circumstances, we do not believe we are required to make any contributions to the Combined Pension Plan in 2026. We estimate that in 2026 we will pay approximately $4 million of benefits directly to participants of our non-qualified pension plans.

We recognize in our consolidated balance sheets the funded status of the legacy Level 3 Parent, LLC qualified defined benefit post-retirement plan. This plan was fully funded as of December 31, 2025 and 2024. Additionally, as previously mentioned, we sponsor unfunded non-qualified pension plans for certain current and former highly-compensated employees. The net unfunded status of our non-qualified pension plans was $29 million and $30 million for the years ended December 31, 2025 and 2024, respectively. Due to the insignificant impact of these pension plans on our consolidated financial statements, we have predominantly excluded them from the remaining employee benefit disclosures in this Note, unless otherwise specifically stated.

Post-Retirement Benefits

Our post-retirement benefit plans provide post-retirement benefits to qualified retirees and allow certain participants to receive benefits at no or reduced cost and other participants to receive benefits on a shared cost basis. The post-retirement benefits not paid by the trusts are funded by us and we expect to continue funding these post-retirement obligations as benefits are paid. The accounting unfunded status of our qualified post-retirement benefit plan was $1.7 billion as of both December 31, 2025 and 2024.

Assets in the post-retirement trusts were substantially depleted as of December 31, 2016; as of December 31, 2019 the Company ceased to pay certain post-retirement benefits through the trusts. No contributions were made to the post-retirement trusts in 2025, nor 2024. Benefits are paid directly by us with available cash. In 2025, we paid $172 million of post-retirement benefits, net of participant contributions and direct subsidies. In 2026, we currently expect to pay directly $181 million of post-retirement benefits, net of participant contributions and direct subsidies.

We anticipate our expected health care cost trend to range from 6.70% to 8.20% in 2026 and grading to 4.50% by 2032. Our post-retirement benefit cost, for certain eligible legacy Qwest retirees and certain eligible legacy CenturyLink retirees, is capped at a set dollar amount. Therefore, those health care benefit obligations are not subject to increasing health care trends after the effective date of the caps.

Additionally, a portion of the service cost is also allocated to certain assets under construction, which are capitalized and reflected as part of property, plant and equipment in our consolidated balance sheets. As a result of ongoing efforts to reduce our workforce, we recognized a one-time charge in our net periodic post-retirement benefit expense in 2024 of $2 million and in our net periodic pension expense in 2023 of $2 million, both for special termination benefit enhancements paid to certain eligible employees upon voluntary retirement.

Our pension plan contains provisions that allow us, from time to time, to offer lump sum payment options to certain former employees in settlement of their future retirement benefits. We record an accounting settlement charge, consisting of the recognition of certain deferred costs of the pension plan associated with these lump sum payments only if, in the aggregate, they exceed or are probable to exceed the sum of the annual service and interest costs for the plan’s net periodic pension benefit cost, which represents the settlement accounting threshold. As of December 31, 2025, the settlement threshold was not reached. In the event of workforce reductions in the future, the annual lump sum payments may trigger settlement accounting.

Plan Assets

We maintain plan assets for our Combined Pension Plan and certain post-retirement benefit plans. As previously noted, assets in the post-retirement benefit plan trusts were substantially depleted as of December 31, 2016. The fair value of post-retirement benefit plan assets was $1 million as of December 31, 2025, 2024 and 2023. Due to the insignificance of these assets on our consolidated financial statements, we have predominantly excluded them from the disclosures of plan assets in this Note, unless otherwise indicated.

The expected rate of return on plan assets is the long-term rate of return we expect to earn on the plan's assets, net of administrative expenses paid from plan assets. It is determined annually based on the strategic asset allocation and the long-term risk and return forecast for each asset class.

Our investment objective for the Combined Pension Plan assets is to achieve an attractive risk-adjusted return over time that will provide for the payment of benefits while minimizing the risk of large losses in funded status. We employ a liability-aware investment strategy designed to reduce the volatility of pension assets relative to pension liabilities. This strategy is evaluated frequently and is expected to evolve over time with changes in the funded status and other factors. Approximately 40% of plan assets is targeted to long-duration investment grade bonds and interest rate sensitive derivatives and 60% is targeted to diversified equity, fixed income and private market investments that are expected to outperform the liability with moderate funded status risk. At the beginning of 2026, our expected annual long-term rate of return on pension assets before consideration of administrative expenses is assumed to be 7.0%. Administrative expenses, including projected Pension Benefit Guaranty Corporation premiums, reduce the annual long-term expected return, net of administrative expenses, to 6.5%.

Permitted investments: Plan assets are managed consistent with the restrictions set forth by the Employee Retirement Income Security Act of 1974, as amended.

Fair value measurements: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We measure plan assets at fair value using a hierarchy that prioritizes observable inputs. For additional information on the fair value hierarchy, see Note 14 — Fair Value of Financial Instruments.

As of December 31, 2025, we used the following valuation techniques to measure fair value for assets. There were no changes to these methodologies during 2025:

Level 1 — Assets were valued using the closing price reported in the active market in which the individual security was traded. U.S. Treasury securities are valued at the bid price reported in an active market in which the security is traded. Variation margin due from/(to) brokers is valued at the expected next day cash settlement amount.

Level 2 — Assets were valued using quoted prices in markets that are not active, broker dealer quotations, and other methods by which all significant inputs were observable at the measurement date. Fixed income securities primarily utilize observable market information and are based on a spread to U.S. Treasury securities and consider yields available on comparable securities of issuers with similar credit ratings, the new issue market for similar securities, secondary trading markets and dealer quotes. Option adjusted spread models are utilized to evaluate fixed income securities that have early redemption features. Derivative securities traded over the counter are valued based on gains or losses due to fluctuations in indices, interest rates, foreign currency exchange rates, security prices or other underlying factors. Repurchase agreements are valued based on expected settlement per the contract terms.

Level 3 — Assets were valued using unobservable inputs where little or no market data exists at the measurement date. Valuation methods may consider a range of factors, including estimates provided by the investment entity.

The Combined Pension Plan's assets are invested in various asset categories utilizing multiple strategies and investment managers. Interests in commingled funds are fair valued using a practical expedient to the net asset value ("NAV") per unit (or its equivalent) of each fund. The NAV reported by the fund manager is based on the market value of the underlying investments owned by each fund, minus its liabilities, divided by the number of shares outstanding. Commingled funds can be redeemed at NAV, with a frequency that includes daily, monthly, quarterly, semi-annually and annually. These commingled funds include redemption notice periods between same day and 95 days. Investments in private funds, primarily limited partnerships, represent long-term commitments with a fixed maturity date and are also valued at NAV. The plan has unfunded commitments related to certain private fund investments, which in aggregate are not material to the plan. Valuation inputs for these private fund interests are generally based on assumptions and other information not observable in the market. Underlying investments held in funds are aggregated and are classified based on the fund mandate. Investments held in separate accounts are individually classified.

Below is an overview of the asset categories and the underlying strategies used in the preceding tables:

(a) Investment grade bonds represent investments in U.S. Treasury securities, agencies, corporate bonds, mortgage-backed securities, asset-backed securities and commercial mortgage-backed securities.

(b) High yield bonds represent investments in below investment grade fixed income securities.

(c) Emerging market bonds represent investments issued by governments and other entities located in emerging countries.

(d) U.S. stocks represent investments in stocks of U.S. based companies.

(e) Non-U.S. stocks represent investments in companies based in developed countries outside the U.S.

(f) Emerging market stocks represent investments in stocks of companies located in emerging markets.

(g) Private equity represents non-public investments in domestic and foreign buyout and venture capital funds. Private equity funds are primarily structured as limited partnerships and are valued according to the valuation policy of each partnership, subject to prevailing accounting and other regulatory guidelines.

(h) Private debt represents non-public investments in performing and distressed credits.

(i) Market neutral hedge funds hold investments in a diversified mix of instruments that are intended in combination to exhibit low correlations to market fluctuations. These investments are typically combined with futures to achieve uncorrelated excess returns over various markets.

(j) Directional hedge funds represent investments that may exhibit somewhat higher correlations to market fluctuations than the market neutral hedge funds.

(k) Real estate represents investments in a diversified portfolio of real estate properties.

125

Table of Contents
(l) Derivatives include exchange traded futures contracts as well as privately negotiated over the counter contracts. The market values represent gains or losses that occur due to differences between stated contract terms and fluctuations in underlying market instruments.

(m) Repurchase agreements and other obligations includes contracts where the security owner sells a security with the agreement to buy it back at a future date and price. Other obligations include obligations to repay cash collateral held by a plan, net liability for investment purchases pending settlement, and accrued plan expenses.

(n) Cash equivalents and short-term investments represent investments that are used in conjunction with derivatives positions or are used to provide liquidity for the payment of benefits or other purposes.

Derivative instruments: The plan uses exchange‑traded futures and centrally cleared/OTC swaps primarily to align interest‑rate exposure with liabilities and to efficiently maintain equity exposure. Fair values of these instruments are included within the fair value hierarchy.

Concentrations of risk: Investments, in general, are exposed to various risks, such as significant world events, interest rate, credit, foreign currency and overall market volatility risk. These risks are managed by broadly diversifying assets across numerous asset classes and strategies with differing expected returns, volatilities and correlations. Risk is also broadly diversified across numerous market sectors and individual companies. Financial instruments that potentially subject the plans to concentrations of counterparty risk consist principally of investment contracts with high quality financial institutions. These investment contracts are typically collateralized obligations or are actively managed, limiting the amount of counterparty exposure to any one financial institution. Although the investments are well diversified, the value of plan assets could change materially depending upon the overall market volatility, which could affect the funded status of the plan.

Certain gains and losses are allocated between assets sold during the year and assets still held at year-end based on transactions and changes in valuations that occurred during the year. These allocations also impact our calculation of net acquisitions and dispositions.

For the year ended December 31, 2025, the investment program produced actual gains on Combined Pension Plan assets of $473 million as compared to expected returns of $254 million, for a difference of $219 million. For the year ended December 31, 2024, the investment program produced actual gains on Combined Pension Plan assets of $107 million as compared to the expected returns of $272 million, for a difference of $165 million. The short-term annual returns on plan assets will almost always be different from the expected long-term returns and the plans could experience net gains or losses, due primarily to the volatility occurring in the financial markets during any given year.

Other Benefit Plans

Medicare Prescription Drug, Improvement and Modernization Act of 2003

We sponsor post-retirement health care plans with several benefit options that provide prescription drug benefits that we deem actuarially equivalent to or exceeding Medicare Part D. We recognize the impact of the federal subsidy received under the Medicare Prescription Drug, Improvement and Modernization Act of 2003 in the calculation of our post-retirement benefit obligation and net periodic post-retirement benefit expense.

Health Care and Life Insurance

We provide health care and life insurance benefits to essentially all our active employees. We are largely self-funded for the cost of the health care plan. Our health care benefit expense for current employees was $336 million, $281 million and $288 million for the years ended December 31, 2025, 2024 and 2023, respectively. Union-represented employee benefits are based on negotiated collective bargaining agreements. Employees contributed $71 million, $79 million, $89 million for the years ended December 31, 2025, 2024 and 2023, respectively. Our group basic life insurance plans are fully insured and the premiums are paid by us.

401(k) Plans

We sponsor a qualified defined contribution plan covering substantially all our U.S. employees. Under this plan, employees may contribute a percentage of their annual compensation up to certain maximums, as defined by the plan and by the Internal Revenue Service. Currently, we match a percentage of employee contributions in cash. As of December 31, 2025 and 2024, the assets of the plan included approximately 7 million and 8 million shares of our common stock, all of which were the result of the combination of previous employer match and participant directed contributions. We recognized expenses related to this plan of $80 million, $82 million and $87 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Deferred Compensation Plans

We sponsor non-qualified deferred compensation plans for various groups that included certain of our current and former highly compensated employees. The value of liabilities related to these plans was not significant.

Subsequent Event

In January 2026, we made a voluntary contribution of $101 million to the trust for the Combined Pension Plan.

Note 12 — Stock-Based Compensation

We maintain an equity incentive program that allows our Board of Directors (through its Human Resources and Compensation Committee or a senior officer acting under delegated authority) to grant incentives to certain employees and outside directors in one or more forms, including: incentive and non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and market and other equity-based awards.

Restricted Stock Awards and Restricted Stock Unit Awards

We grant equity based restricted stock and restricted stock units that contain service only conditions for vesting (“Service Awards”), awards that contain both service and market conditions for vesting (“Market Awards”) and awards that contain both service and performance conditions for vesting (“Performance Awards”). The fair value of Service Awards is based upon the closing stock price on the accounting grant date and the awards generally vest over periods ranging from one to four years. The fair value of Market Awards is determined using Monte-Carlo simulations and the awards vest over periods up to three years. The number of shares ultimately earned for Market Awards is typically based upon our total shareholder return as compared to the return of selected peer companies and can range between 0% and 200% of the target number of shares for the award. The fair value of Performance Awards is based upon the closing stock price on the accounting grant date; however, the award value may increase, or decrease based upon the extent to which the performance conditions are satisfied. Performance Awards vest over periods of up to three-years and specify a target number of shares for the award. The recipient ultimately can receive between 0% and 200% of the target number of shares depending upon the extent to which the performance conditions are satisfied.

The following table summarizes activity involving restricted stock and restricted stock unit awards for the year ended December 31, 2025:

Table of Contents
During 2025, we granted 19.0 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $5.10. During 2024, we granted 14.3 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $1.69. During 2023, we granted 14.8 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $1.85. The total fair value of restricted stock and restricted stock unit awards that vested during 2025, 2024 and 2023, was $44 million, $27 million and $21 million, respectively. We do not estimate forfeitures but recognize them as they occur.

Compensation Expense and Tax Benefit

For Service Awards that vest ratably over the service period, we recognize compensation expense on a straight-line basis over the requisite service period for the entire award. For Service Awards that vest at the end of the service period and for Market Awards, we recognize compensation expense over the service period. For our Performance Awards, we recognize compensation expense over the service period and based upon the expected performance outcome, until the final performance outcome is determined. Total compensation expense for all stock-based payment arrangements for the years ended December 31, 2025, 2024 and 2023, was $48 million, $29 million and $52 million, respectively. Our tax benefit recognized in the consolidated statements of operations for our stock-based payment arrangements for the years ended December 31, 2025, 2024 and 2023, was $12 million, $7 million and $12 million, respectively. As of December 31, 2025, there was $83 million of total unrecognized compensation expense related to our stock-based payment arrangements, which we expect to recognize over a weighted-average period of 1.5 years.

Our calculation of diluted loss per share of common stock excludes non-vested restricted stock awards that are anti-dilutive based upon the terms of the award. Such shares were 11.9 million, 16.0 million and 22.5 million for 2025, 2024 and 2023, respectively.

Note 14 — Fair Value of Financial Instruments

Our financial instruments consist of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, long-term debt (excluding finance lease and other obligations), certain equity investments and certain indemnification obligations. Due primarily to their short-term nature, the carrying amounts of our cash, cash equivalents, restricted cash, accounts receivable and accounts payable approximate their fair values.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs using the below-described fair value hierarchy.

We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:
Input LevelDescription of Input
Level 1Observable inputs such as quoted market prices in active markets.
Level 2Inputs other than quoted prices in active markets that are either directly or indirectly observable.
Level 3Unobservable inputs in which little or no market data exists.

The effective tax rate for the year ended December 31, 2025 includes a $333 million favorable impact from statute of limitation releases on uncertain tax positions previously disclosed. The effective tax rate for December 31, 2024 includes a $135 million favorable impact from the exclusion of cancellation of debt income ("CODI") under Section 108 of the Internal Revenue Code. The effective tax rate for the year ended December 31, 2023 includes a $2.2 billion unfavorable impact of a non-deductible goodwill impairment and a $137 million favorable impact as a result of utilizing available capital losses generated by the sale of our Latin American business in 2022.

As of December 31, 2025, we have determined that a portion of our undistributed earnings in India are no longer permanently reinvested, resulting in the recognition of an immaterial deferred tax liability. We continue to assert that undistributed earnings of our subsidiaries in all other foreign jurisdictions are indefinitely reinvested.

Of the $2.1 billion and $2.8 billion net deferred tax liability as of December 31, 2025 and 2024, respectively, $2.3 billion and $2.9 billion is reflected as a long-term liability and $145 million and $96 million is reflected as a net noncurrent deferred tax asset, in other, net on our consolidated balance sheets as of December 31, 2025 and 2024, respectively.

Income taxes receivable as of December 31, 2025 and 2024, were $468 million and $483 million, respectively.

As of December 31, 2025, we had federal NOLs of approximately $982 million, net of expirations from limitations under Section 382 of the Internal Revenue Code and uncertain tax positions, for U.S. federal income tax purposes. We expect to use substantially all of these NOLs to reduce our future federal tax liabilities, although the timing of that use will depend upon our future earnings and future tax circumstances. Our ability to use these NOLs is subject to annual limits imposed by Section 382. If unused, approximately $570 million of pre-2018 NOLs will expire between 2027 and 2031.

As of December 31, 2025, we had state NOLs of $11 billion (net of uncertain tax positions). Our ability to use these NOLs is subject to annual limits under state law.

We establish valuation allowances when necessary to reduce the deferred tax assets to amounts we expect to realize. As of December 31, 2025, we established a valuation allowance of $328 million as it is more likely than not that this amount of NOLs will not be utilized prior to expiration. Our valuation allowance as of December 31, 2025 and 2024 is primarily related to NOLs. This valuation allowance decreased by $15 million during 2025, primarily due to changes in our state NOL carryforwards.

A reconciliation of the change in our gross unrecognized tax benefits (excluding both interest and any related federal benefit) for the years ended December 31, 2025 and 2024 is as follows:
20252024
 (Dollars in millions)
Unrecognized tax benefits at beginning of year$1,263 1,424 
Increase (decrease) in tax positions of prior periods netted against deferred tax assets1 (4)
Decrease in tax positions taken in the current year(7)(64)
Increase in tax positions taken in the prior year4 65 
Decrease due to payments/settlements(1) 
Decrease from the lapse of statute of limitations(394)(158)
Unrecognized tax benefits at end of year$866 1,263 

As of December 31, 2025, the total amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate was $653 million. The unrecognized tax benefits also include tax positions that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes, which would not impact the effective tax rate but could impact cash tax amounts payable to taxing authorities.

Our policy is to reflect interest expense associated with unrecognized tax benefits in income tax (benefit) expense. We had accrued interest (presented before related tax benefits) of approximately $306 million and $217 million as of December 31, 2025 and 2024, respectively.

We, or at least one of our subsidiaries, file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2004. The Internal Revenue Service and state and local taxing authorities reserve the right to audit any period where NOLs are available.

Based on our current assessment of various factors, including (i) the potential outcomes of these ongoing examinations, (ii) the expiration of statute of limitations for specific jurisdictions, (iii) the negotiated settlement of certain disputed issues, and (iv) the administrative practices of applicable taxing jurisdictions, it is reasonably possible that the related unrecognized tax benefits for uncertain tax positions previously taken may decrease by up to $287 million within the next 12 months. The actual amount of such decrease, if any, will depend on several future developments and events, many of which are outside our control.

In July 2025, the U.S. enacted the “One, Big Beautiful Bill Act” (the “OBBBA”), which permanently allows 100% bonus depreciation, immediate expensing for domestic R&D, and favorable changes to interest expense limitations. These provisions did not have a material impact on our 2025 effective tax rate but significantly reduced our federal income tax liability. The Company filed a refund claim for $400 million of federal estimated income taxes in July 2025 that it anticipates receiving in the first half of 2026.

The OECD has issued Pillar Two model rules introducing a new global minimum corporate tax of 15% for tax years effective after December 31, 2023. While the U.S. has not adopted Pillar Two legislation, certain countries in which we operate have already adopted legislation to implement Pillar Two. On January 5, 2026, the OECD announced the Side-by-Side ("SbS") package, implemented as administrative guidance modifying the operation of Pillar Two rules, which would fully exempt U.S.-parented groups from the application certain Pillar Two top-up taxes. The SbS package also extends the current Transitional Country-by-Country Reporting ("CbCR") Safe Harbor by one year, through the end of fiscal year of 2027. The Pillar Two rules have increased our compliance requirements but did not materially impact our 2025 results. We continue to monitor evolving global and domestic tax legislation and administrative guidance.

Note 16 — Segment Information

Our business is managed based on customer-facing sales channels to align with how we support our customers. Our chief operating decision maker ("CODM"), who is our CEO, makes decisions and assesses the performance of the Company reviewing two segments: Business and Mass Markets. Our reportable segments have not been aggregated.
136

Table of Contents

Under our Business segment, we provide products and services to meet the needs of our enterprise and wholesale customers under five distinct sales channels — Large Enterprise, Mid-Market Enterprise, Public Sector, Wholesale and International and Other. For Business segment revenue, we report the following product categories: Grow, Nurture, Harvest and Other, in each case through the sales channels outlined above. The Business segment included the results of our EMEA business prior to the sale on November 1, 2023.

Under our Mass Markets segment, we provide products and services to residential and small business customers. We report the following product categories: Fiber Broadband, Other Broadband, and Voice and Other.

See detailed descriptions of these product and service categories in Note 4 — Revenue Recognition.

As described in more detail below, our segments are managed based on the direct costs of providing services to their customers and directly associated headcount and non-headcount operating expenses. Shared costs are managed separately and included in "other unallocated expense" in the table included below under the heading "— Revenue and Expenses." As referenced above, we reclassified certain prior period amounts to conform to the current period presentation. See Note 1 — Background and Summary of Significant Accounting Policies for additional detail on these changes. The CODM uses adjusted EBITDA as the key indicator in assessing performance and allocating resources for both the Business segment and Mass Markets segment.

The following tables summarize our segment results for 2025, 2024 and 2023 based on the segment categorization we were operating under as of December 31, 2025.

Revenue and Expenses

Our segment revenue includes all revenue from our two segments as described in more detail above. Our segment revenue is based upon each customer's classification. We report our segment revenue based upon all services provided to that segment's customers. Our segment expenses include (i) specific cost of service expenses incurred as a direct result of providing services and products to segment customers, (ii) headcount costs, which primarily includes salaries, commissions, and group insurance, and (iii) non-headcount costs, which primarily include legal and other professional fees, marketing and advertising expenses, other network-related expenses, and external commissions. We have not allocated assets or debt to specific segments.

The following items are excluded from our segment results, because they are centrally managed and not monitored by or reported to our chief operating decision maker by segment:

network expenses not incurred as a direct result of providing services and products to segment customers and centrally managed expenses such as Finance, Human Resources, Legal, Marketing, Product Management, and IT, all of which are reported as "other unallocated expense" in the table below;

depreciation and amortization expense;

goodwill or other impairments;

interest expense;

stock-based compensation;

other income and expense items; and

income tax expense.

Note 17 — Commitments, Contingencies and Other Items

We are subject to various claims, legal proceedings and other contingent liabilities, including the matters described below, which individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows.

We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Subject to these limitations, as of December 31, 2025 and December 31, 2024, we had accrued $71 million and $78 million, respectively, in the aggregate for our litigation and non-income tax contingencies, which is included in Other current liabilities or Other liabilities on our consolidated balance sheets as of such dates. Although we quantify our exposure for certain matters below, we cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $71 million accrual as of December 31, 2025 due to the inherent uncertainties and speculative nature of contested proceedings. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.

In this Note, a reference to a "putative" class action means a class has been alleged, but not certified, in that matter.

Principal Proceedings

Houser Shareholder Suit

Lumen and certain of its current and former officers and directors were named as defendants in a putative shareholder class action lawsuit filed on June 12, 2018 in the Boulder County District Court of the state of Colorado, captioned Houser et al. v. CenturyLink, et al. The original complaint asserted claims on behalf of a putative class of former Level 3 Communications, Inc. ("Level 3") shareholders who became CenturyLink, Inc. shareholders as a result of our acquisition of Level 3. It alleged that the proxy statement provided to the Level 3 shareholders failed to disclose various material information, including information about strategic revenue, customer loss rates, and customer account issues, among other items. The original complaint sought damages, costs and fees, rescission, rescissory damages, and other equitable relief. In May 2020, the court dismissed the original complaint. The plaintiffs appealed that decision, and in March 2022, the appellate court affirmed the district court's order in part and reversed it in part. It then remanded the case to the district court for further proceedings. The plaintiffs filed an amended complaint asserting the same claims and prayer for relief, and we filed a motion to dismiss. The court granted our motion to dismiss in May 2023 and the plaintiffs appealed that dismissal. In August 2024, the appellate court set aside the trial court's dismissal. In October 2024, we filed a petition with the Colorado Supreme Court seeking a review of the appellate court's decision, and the petition for review was granted.

Lead-Sheathed Cable Litigation

Disclosure Litigation

On September 15, 2023, a purported shareholder of Lumen filed a putative class action complaint originally captioned Glauber, et al. v. Lumen Technologies (now captioned In re Lumen Technologies, Inc. Securities Litigation II, Case 3:23-cv-01290), in the U.S. District Court for the Western District of Louisiana. The complaint alleged that Lumen and certain of its current and former officers violated the federal securities laws by omitting or misstating material information related to Lumen’s responsibility for environmental degradation allegedly caused by the lead sheathing of certain telecommunications cables. The court appointed lead plaintiffs who filed an amended complaint, seeking money damages, attorneys’ fees and costs, and other relief. On March 31, 2025, the court granted Lumen's motion to dismiss plaintiffs' claims with prejudice. On April 30, 2025, the plaintiffs filed an appeal which is captioned McLemore v. Lumen Technologies, Case 25-30264, in the U.S. Court of Appeals for the Fifth Circuit. On January 30, 2026, the Fifth Circuit reversed on prejudice only and modified the dismissal to be without prejudice.

Derivative Litigation

On June 11, 2024, a purported shareholder of Lumen filed a shareholder derivative complaint on behalf of Lumen captioned Brown v. Johnson, et al., Case 3:24-cv-00798-TAD-KDM, in the U.S. District Court for the Western District of Louisiana. The complaint alleges claims for breach of fiduciary duty, violations of the federal securities laws, and other causes of action against current and former officers and directors of Lumen relating to placement or presence of lead-sheathed telecommunications cables. The complaint seeks damages, injunctive relief, and attorneys' fees. Substantially similar derivative cases have been filed as follows: (i) on August 9, 2024, Pourarian v. Johnson, et al., Case 3:24-cv-01071-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (ii) on September 9, 2024, Capistrano v. Johnson, et al., Case 3:24-cv-01234-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (iii) on September 16, 2024, Vogel v. Perry, et al., Case 2024-3360 in the 4th Judicial District Court for the Parish of Ouachita, State of Louisiana, subsequently removed on September 17, 2024 to the U.S. District Court for the Western District of Louisiana as Case 3:24-cv-01274-TAD-KMM; and (iv) on September 25, 2024, Murray v. Allen, et al., Case 3:24-cv-01320 in the U.S. District Court for the Western District of Louisiana. In April 2025, the court consolidated the Brown, Pourarian, Capistrano, and Murray actions and stayed the consolidated action pending further developments in In re Lumen Technologies, Inc. Securities Litigation II. In July 2025, the court similarly stayed the Vogel action.

Environmental Litigation

Parish of St. Mary

On July 9, 2024, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, Case 138575, asserting claims on behalf of all parishes, municipalities, and citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. The case was removed to the United States District Court Western District of Louisiana Lafayette Division, Case 6:24-CV-01001-RRS-DJA. On December 6, 2024, the plaintiffs voluntarily dismissed the class action complaint without prejudice. On December 13, 2024, St. Mary’s Parish along with other parishes, municipalities, and two individuals served a notice of intent to file citizen suit under the Louisiana Environmental Quality Act, asserting claims identical to the class action which the plaintiffs voluntarily dismissed. In April 2025, the Village of Parks (one of the municipalities which had served a notice of intent to file a citizen suit) served Lumen with a petition in an action captioned Village of Parks v. Lumen Technologies, Inc., Case 95026, in the 16th Judicial District Court for the Parish of St. Martin, State of Louisiana. The Village of Parks petition seeks damages and injunctive relief under Louisiana state law relating to the above-described allegations about lead-sheathed telecommunications cables.

Blum

On November 6, 2023, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, Case 137935, asserting claims on behalf of all citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T, BellSouth, Verizon, and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. The case has been removed to Federal Court in the United States District Court Western District of Louisiana Lafayette Division, Case 6:23-CV-01748. In December 2024, the plaintiffs filed an amended complaint and a motion for remand. In September 2025, the motion to remand was denied.

State Tax Suits

Since 2012, a number of Missouri municipalities have asserted claims in the Circuit Court of St. Louis County, Missouri, alleging that we and several of our subsidiaries have underpaid taxes. These municipalities are seeking, among other things, declaratory relief regarding the application of business license and gross receipts taxes and back taxes from 2007 to the present, plus penalties and interest. In a February 2017 ruling in connection with one of these pending cases, the court entered an order awarding the plaintiffs $4 million and broadening the tax base on a going-forward basis. We appealed that decision to the Missouri Supreme Court. In December 2019, it affirmed the circuit court's order in some respects and reversed it in others, remanding the case to the circuit court for further proceedings. The Missouri Supreme Court's decision reduced our exposure in the case. In a June 2021 ruling in one of the pending cases, another trial court awarded the cities of Columbia and Joplin approximately $55 million, plus statutory interest. On appeal, the Missouri Court of Appeals affirmed in part and reversed in part, vacated the judgment and remanded the case to the trial court with instructions for further proceedings consistent with the Missouri Supreme Court's decision. In July 2025, a settlement was reached with the cities of Columbia and Joplin.

FCRA Litigation

In November 2014, a putative class action complaint captioned Bultemeyer v. CenturyLink, Inc. was filed in the United States District Court for the District of Arizona, Case CV-14-02530-PHX-SPL, alleging violations of the Fair Credit Reporting Act (the "FCRA"). In February 2017, the case was dismissed for lack of standing. The plaintiff appealed and the Ninth Circuit reversed and remanded. Class certification was contested and ultimately granted in 2023. The Ninth Circuit denied Lumen’s request to appeal the class certification ruling. A jury trial was conducted in September 2024. The jury found that CenturyLink willfully violated the FCRA and awarded each class member $500 for statutory damages and $2,000 for punitive damages. The district court denied Lumen's post-trial motions for relief, and on October 16, 2024, Lumen filed an appeal which is captioned Bultemeyer v. CenturyLink, Inc., Case 24-6413, in the U.S. Court of Appeals for the Ninth Circuit. We have not accrued a contingent liability for this matter. While liability is possible, we have not determined it to be probable, and damages exposure, if any, is uncertain.

December 2018 Outage Proceedings

We experienced an outage on one of our transport networks that impacted voice, IP, 911, and transport services for some of our customers between the 27th and 29th of December 2018. We believe that the outage was caused by a faulty network management card from a third-party equipment vendor.

The FCC and four states initiated formal investigations. In November 2020, following the FCC's release of a public report on the outage, we negotiated a settlement which was disclosed by the FCC in December 2020. The amount of the settlement was not material to our financial statements.

In December 2020, the Staff of the Washington Utilities and Transportation Commission ("WUTC") filed a complaint against us based on the December 2018 outage, seeking penalties of approximately $7 million for alleged violations of Washington regulations and laws. The Washington Attorney General's office sought penalties of $27 million. Following trial, the WUTC issued an order imposing a penalty of approximately $1 million. On April 15, 2024, we appealed that decision to the Washington State Court of Appeals. In August 2025, the Court of Appeals denied the appeal. In September 2025, we filed a petition for review with the Washington State Supreme Court. In January 2026, the Washington State Supreme Court denied our petition for review.

Latin American Tax Indemnification Claims

In connection with the 2022 divestiture of our Latin American business, the purchaser assumed responsibility for the Brazilian tax claims described in our prior periodic reports filed with the SEC. However, we agreed to indemnify the purchaser for amounts paid with respect to the Brazilian tax claims. The value of this indemnification and others associated with the Latin American business divestiture are included in the indemnification amount as disclosed in Note 14 — Fair Value of Financial Instruments. In addition, there remain other pending proceedings in Brazil, Peru, and other Latin America countries, that, if upheld, could result in a reasonably possible loss of up to approximately $82 million in excess of the amount accrued as of December 31, 2025.

Huawei Network Deployment Investigations

Lumen has received requests from the following federal agencies for information relating to the use of equipment manufactured by Huawei Technologies Company ("Huawei") in Lumen’s networks.

DOJ. Lumen has received a civil investigative demand from the U.S. Department of Justice in the course of a False Claims Act investigation alleging that Lumen Technologies, Inc. and Lumen Technologies Government Solutions, Inc. failed to comply with certain specified requirements in federal contracts concerning their use of Huawei equipment.

FCC. The FCC’s Enforcement Bureau issued a Letter of Inquiry to Lumen Technologies, Inc. regarding its written certifications to the FCC that Lumen has complied with FCC rules governing the use of resources derived from the High Cost Program, Lifeline Program, Rural Health Care Program, E-Rate Program, Emergency Broadband Benefit Program, and the Affordable Connectivity Program. Under these programs, federal funds may not be used to facilitate the deployment or maintenance of equipment or services provided by Huawei, a company the FCC has determined poses a national security threat to the integrity of U.S. communications networks or the communications supply chain.

Team Telecom. The Committee for the Assessment of Foreign Participation in the United States Telecommunications Service Sector (comprised of the U.S. Attorney General, and the Secretaries of the Department of Homeland Security, and the Department of Defense), commonly referred to as Team Telecom, issued questions and requests for information relating to Lumen’s FCC licenses and its use of Huawei equipment.

Marshall Fire Litigation

On December 30, 2021, a wildfire referred to as the Marshall Fire ignited near Boulder, Colorado. The Marshall Fire killed two people, and it burned thousands of acres, including entire neighborhoods. Approximately 300 lawsuits seeking substantial monetary relief have been filed naming as defendants our affiliate Qwest Corporation, an additional telecommunications company, and certain power companies. The complaints involving Qwest have been consolidated with Kupfner et al., v. Public Service Company of Colorado, et al., Case 2022-cv-30195 pending in Colorado District Court, Boulder, Colorado. In September 2025, the court vacated the trial date because the defendants reached agreements in principle to settle with virtually all of the plaintiffs, subject to final documentation. The court has held periodic status conferences and set a further status conference for February 26, 2026.

Minnesota State Income Tax Appeal

In May 2025, the Minnesota Department of Revenue issued an order (the "Order") denying the Company's petition for a separate allocation or separate apportionment of the taxable gain resulting from the 2022 divestiture of a portion of our incumbent local exchange carrier ("ILEC") business and making other minor adjustments. The Order seeks to assess additional income tax, penalties, and interest for the 2021 and 2022 tax years. On August 4, 2025, Lumen filed an appeal of the Order disputing this assessment, which is captioned Lumen Technologies, Inc. v. Commissioner of Revenue, Docket No. 9744-R., in the Minnesota Tax Court. The Company previously established an uncertain tax position for this item.

Other Proceedings, Disputes and Contingencies

From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, regulatory hearings relating primarily to our rates or services, actions relating to employee claims, tax issues, or environmental law issues, grievance hearings before labor regulatory agencies, miscellaneous third-party tort actions, or commercial disputes.

We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial within the next twelve months if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers.

We are subject to various foreign, federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $300,000 in fines and penalties. In addition, in the past we acquired companies that had installed lead-sheathed cables several decades earlier, or had operated certain manufacturing companies in the first part of the 1900s. Under applicable environmental laws, we could be named as a potentially responsible party for a share of the remediation of environmental conditions arising from the historical operations of our predecessors.

The outcomes of these other proceedings described under this heading are not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on us.

The matters listed in this Note do not reflect all our contingencies. The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings we currently consider insignificant may ultimately affect us materially.

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”)) designed to provide reasonable assurance that the information required to be disclosed by us in the reports we file or furnish under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. These include controls and procedures designed to ensure this information is accumulated and communicated to our senior leadership team, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our President and Chief Executive Officer, Kate Johnson, and our Executive Vice President and Chief Financial Officer, Chris Stansbury, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2025, our disclosure controls and procedures were effective at the reasonable assurance level.

Inherent Limitations of Disclosure Controls and Procedures

The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing and evaluating the controls and procedures, the assumptions used in identifying the likelihood of future events and the inability to eliminate misconduct completely. As a result, there can be no assurance that our disclosure controls and procedures will detect all errors or fraud. By their nature, our or any system of disclosure controls and procedures can provide only reasonable assurance regarding management's control objectives.

Internal Control Over Financial Reporting

Management’s Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act), a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our evaluation under the framework of COSO, our management concluded that our internal control over financial reporting was effective as of December 31, 2025. The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by KPMG LLP, as stated in their report entitled "Opinion on Internal Control Over Financial Reporting" appearing in Item 8, which is incorporated into this item by reference.

Changes in Internal Control Over Financial Reporting

During the three months ended December 31, 2025, the Company implemented the first phase of a new enterprise resource planning (“ERP”) system. The remaining phase of the ERP implementation is expected to be completed in 2026. The ERP implementation included changes to transaction processing and financial reporting systems and controls over these new systems. The Company will continue to monitor further changes during subsequent periods to evaluate the effectiveness of internal controls over financial reporting.

Except for changes in controls related to the ERP implementation noted above, there have not been any other changes in the Company’s internal control over financial reporting during the three months ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

(a)As previously disclosed, at the Company’s 2025 annual meeting of shareholders, shareholders approved a shareholder proposal that requested the Company to remove all voting standards greater than a “simple majority” and replace them with a majority of votes cast standard, or the closest standard consistent with applicable laws. On February 18, 2026, the Company’s Board of Directors adopted the Amended and Restated Bylaws of the Company (the “2026 A&R Bylaws”), which revised the Company’s Amended and Restated Bylaws as previously in effect to change the voting standard for (a) the approval by shareholders of adjournments to shareholder meetings and (b) the approval by shareholders of changes to the agenda or order of business for a meeting of shareholders to a majority of votes cast standard. The foregoing description of the changes included in the 2026 A&R Bylaws is not complete and is qualified in its entirety by reference to the 2026 A&R Bylaws. The 2026 A&R Bylaws, along with a copy marked to show the changes from the Company’s Amended and Restated Bylaws as previously in effect, are filed herewith as Exhibits 3.2 and 3.3, respectively, and incorporated herein by reference.

(b)During the quarter ended December 31, 2025, none of our directors or officers (as defined in Rule 16a-1 under the Exchange Act) adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement" (as those terms are defined in Item 408(a) of Regulation S-K).

Section 10.Indemnification.
10.1Definitions. As used in this Section 10:
(a)The term “Change of Control” shall mean (i) an acquisition by any person (within the meaning of Section 13(d)(3) or l4(d)(2) of the Securities Exchange Act of 1934, as amended) of beneficial ownership of 20% or more of the combined voting power of the Corporation's then outstanding voting securities; (ii) during any period of two consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the Corporation and any new director whose election by the Board of Directors or nomination for election by the Corporation's shareholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or (iii) the consummation of a merger or consolidation involving the Corporation if either (x) the shareholders of the Corporation, immediately before such merger or consolidation, do not own, immediately following such merger or consolidation, more than 50% of the combined voting power of the outstanding voting securities of the entity paying cash or issuing stock in connection with the merger or consolidation or (y) the members of the Board of Directors of the Corporation immediately before such merger or consolidation do not constitute, immediately following the merger or consolidation, a majority of the members of the board of directors (or similar governing body) of the entity paying cash or issuing stock in connection with the merger or consolidation. Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because 20% or more of the Corporation’s then outstanding voting securities is acquired by (l) a trustee or other fiduciary holding securities under one or more employee benefit plans maintained by the Corporation or any of its subsidiaries or (2) any entity that, immediately prior to such acquisition, is owned directly or indirectly by the shareholders of the Corporation in the same proportion as their ownership of shares in the Corporation immediately prior to such acquisition.
(b)The term “Claim” shall mean any threatened, pending or concluded claim, action, suit, or proceeding, including discovery, whether civil, criminal, administrative, arbitrative or investigative and whether made judicially or extra-judicially, or involving
    6


Indemnitee solely as a witness or person required to give evidence, or any separate issue or matter therein, as the context requires, but shall not include any action, suit or proceeding initiated by Indemnitee against the Corporation (other than to enforce the terms of this Section), or initiated by Indemnitee against any director or officer of the Corporation unless the Corporation has joined in or consented in writing to the initiation of such action, suit or proceeding.
(c)The term “Determining Body” shall mean (i) if there are two or more qualified directors (as defined in Section 1-140(18B) of the LBCA), all of the qualified directors (“Disinterested Directors”), or (ii) special legal counsel (A) selected by the Disinterested Directors or (B) if there are fewer than two Disinterested Directors selected by the Board of Directors (in which selection directors who do not qualify as Disinterested Directors may participate); provided, however, that following a Change of Control, with respect to all matters thereafter arising out of acts, omissions or events occurring prior to or after the Change of Control concerning the rights of Indemnitee to seek indemnification, such determination shall be made by special legal counsel selected by the Board of Directors in the manner described above in this Section 10.1(c) (which selection shall not be unreasonably delayed or withheld) from a panel of three counsel nominated by Indemnitee. Such counsel (“Special Counsel”) shall not have otherwise performed services for the Corporation, Indemnitee or their respective affiliates (other than services as special legal counsel in connection with similar matters) within the five years preceding its engagement. If Indemnitee fails to nominate Special Counsel within ten business days following written request by the Corporation, the Board of Directors shall select such counsel. Such counsel shall not be a person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Corporation or Indemnitee in an action to determine Indemnitee's rights under this Section 10, nor shall Special Counsel be any person who has been sanctioned or censured for ethical violations of applicable standards of professional conduct. The Corporation agrees to pay the reasonable fees and costs of the Special Counsel referred to above and to fully indemnify such Special Counsel against any and all expenses, claims, liabilities and damages arising out of or relating to this Section 10.1(c) or its engagement pursuant hereto. The Determining Body shall determine in accordance with Section 10.3 whether and to what extent Indemnitee is entitled to be indemnified under this Section and shall render a written opinion to the Corporation and to Indemnitee to such effect.
(d)The term “D&O Insurance” shall mean directors and officers liability insurance.
(e)The term "Disbursing Officer" shall mean, with respect to a Claim, the Chief Executive Officer of the Corporation or, if the Chief Executive Officer is a party to the Claim as to which advancement or indemnification is being sought, any officer who is not a party to the Claim and who is designated by the Chief Executive Officer, which designation shall be made promptly after the Corporation's receipt of Indemnitee's initial request for advancement or indemnification and communicated to Indemnitee.
(f)The term “Expenses” shall mean any reasonable expenses or costs (including, without limitation, attorney’s fees, fees of experts retained by attorneys, judgments, punitive or exemplary damages, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee with respect to a Claim, except that Expenses shall not include any amount paid in settlement of a Claim against Indemnitee (i) by or in the right of the Corporation, or (ii) that the Corporation has not approved, which approval will not be unreasonably delayed or withheld.
    7


(g)The term “Indemnitee” shall mean each Director and officer and each former Director and officer of the Corporation.
(h)The term “Section” or “Section 10” shall mean Article II, Section 10, of these Bylaws, in its entirety, unless the context otherwise provides.
(i)The term “Standard of Conduct” shall mean conduct by an Indemnitee with respect to which a Claim is asserted that was in good faith and that Indemnitee reasonably believed to be in, or (in the case of conduct other than in an official capacity) not opposed to, the best interest of the Corporation, and, in the case of a Claim that is a criminal action or proceeding, conduct that the Indemnitee had no reasonable cause to believe was unlawful. The termination of any Claim by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not meet the Standard of Conduct.
10.2Advancement of Expenses.
(a)Subject to Indemnitee’s furnishing the Corporation with (i) a written undertaking, in a form reasonably satisfactory to the Corporation, to repay such amount if it is ultimately determined that Indemnitee is not entitled under this Section 10 to indemnification therefor and (ii) a written affirmation meeting the requirements of LBCA Section 1-853(A)(1), the Corporation shall advance Expenses to Indemnitee in advance of the final disposition of any Claim involving Indemnitee; provided, however, that Indemnitee will return, without interest, any such advance that remains unspent immediately following resolution of the Claim to which the advance related, and provided further, that advances of such Expenses by the Corporation's D&O Insurance carrier shall be treated, for purposes of this Section 10.2(a), as advances by the Corporation. The written undertaking by Indemnitee must be an unlimited general obligation of Indemnitee but need not be secured and will be accepted by the Corporation without reference to the financial ability of Indemnitee to make repayment.
(b)Any request for advancement of Expenses shall be submitted by Indemnitee to the Disbursing Officer in writing and shall be accompanied by a written description of the Expenses for which advancement is requested. The Disbursing Officer shall, within 30 days after receipt of Indemnitee's request for advancement, advance such Expenses unsecured, interest-free and without regard to Indemnitee's ability to make repayment, provided that if the Disbursing Officer questions the reasonableness of any such request, that officer shall promptly advance to the Indemnitee the amount deemed by that officer to be reasonable and shall forward immediately to the Board of Directors a copy of the Indemnitee's request and of the Disbursing Officer’s response, together with a written description of that officer’s reasons for questioning the reasonableness of a portion of the advancement sought. The Board of Directors shall, within 30 days after receiving such a request from the Disbursing Officer, determine the reasonableness of the disputed Expenses and notify Indemnitee and the Disbursing Officer of its decision, which shall be final, subject to Indemnitee’s right under Section 10.4 to seek a judicial adjudication of Indemnitee’s rights. The determination shall be made, if there are two or more Disinterested Directors, by the majority vote of the Disinterested Directors, or otherwise by a majority vote of all directors including those who are not Disinterested Directors.
(c)Indemnitee's right to advancement under this Section 10.2 shall include the right to advancement of Expenses incurred by Indemnitee in a suit against the Corporation under Section 10.4 to enforce Indemnitee's rights under this Section. Such right of advancement shall, however, be subject to Indemnitee's obligation pursuant to
    8


Indemnitee’s undertaking described in Section 10.2(a) to repay such advances, to the extent provided in Section 10.4, if it is ultimately determined in the enforcement suit that Indemnitee is not entitled to indemnification for a Claim.
10.3Indemnity.
(a)The Corporation shall, in the manner provided in this Section, indemnify and hold harmless Indemnitee against Expenses incurred in connection with any Claim against Indemnitee (whether as a subject of or party to, or a proposed or threatened subject of or party to, the Claim) or in which Indemnitee is involved solely as a witness or person required to give evidence, by reason of Indemnitee’s position: (A) as a director or officer of the Corporation, (B) as a director or officer of any subsidiary of the Corporation or as a fiduciary with respect to any employee benefit plan of the Corporation, or (C) as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other for profit or not for profit entity or enterprise, if such position is or was held at the request of the Corporation, regardless of when serving in any such position occurred, if (x) Indemnitee is successful in defense of the Claim on the merits or otherwise, as provided in Section 10.3(d), (y) Indemnitee has been found by the Determining Body to have met the Standard of Conduct or (z) Indemnitee has been determined in writing by Special Counsel to have engaged in conduct for which broader indemnification has been made permissible under the Articles of Incorporation for which liability has been eliminated under (or pursuant to) LBCA Section 1-832; provided that no indemnification shall be made in respect of any Claim by or in the right of the Corporation as to which Indemnitee shall have been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable on the basis of receiving a financial benefit to which the Indemnitee was not entitled unless, and only to the extent, a court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as the court shall deem proper, and provided further, that Expenses incurred in connection with a Claim for which Indemnitee has been reimbursed or indemnified by the Corporation’s D&O Insurance carrier shall be credited against the Corporation’s obligation under this Section 10.3(a) with respect to such Claim.
(b)Promptly upon becoming aware of the existence of any Claim with respect to which Indemnitee may seek indemnification hereunder, Indemnitee shall notify the Chief Executive Officer (or, if the Chief Executive Officer is the Indemnitee, the next ranking executive officer who is not an Indemnitee with respect to the Claim) of the existence of the Claim, who shall promptly advise the Board of Directors that establishing the Determining Body will be a matter presented at the next regularly scheduled meeting of the Board of Directors. Failure or delay by Indemnitee in giving such notice shall not excuse performance by the Corporation hereunder except to the extent that, the Corporation did not otherwise learn of the Claim and such failure or delay results in forfeiture by the Corporation of substantial defenses, rights or insurance coverage. After the Determining Body has been established, the Chief Executive Officer or that officer’s delegate shall inform Indemnitee thereof and Indemnitee shall promptly notify the Determining Body, to the extent requested by it, of all facts relevant to the Claim known to Indemnitee.
(c)Indemnitee shall be entitled to conduct the defense of the Claim and to make all decisions with respect thereto, with counsel of Indemnitee’s choice, provided that in the event the defense of the Claim has been assumed by the Corporation through its D&O Insurance carrier or otherwise, then (i) Indemnitee will be entitled to retain

separate counsel from the Corporation’s Counsel (but not more than one law firm plus, if applicable, local counsel at the Corporation’s expense if, but only if, Indemnitee shall reasonably conclude that one or more legal defenses may be available to Indemnitee that are different from, or in addition to, those available to the Corporation or other defendants represented by the Corporation through its D&O Insurance carrier or otherwise, and (ii) the Corporation will not, without the prior written consent of Indemnitee, effect any settlement of the Claim unless such settlement (x) includes an unconditional release of Indemnitee from all liability that is the subject matter of such Claim, (y) does not impose penalties or post-settlement obligations on Indemnitee (except for customary confidentiality obligations), and (z) does not require payment by Indemnitee of money in settlement.
(d)To the extent (i) Indemnitee is successful on the merits or otherwise in defense of any Claim or (ii) Special Counsel has made the written determination described in clause (a)(z) of this Section 10.3, Indemnitee shall be indemnified against Expenses incurred by Indemnitee with respect to the Claim, regardless of whether Indemnitee has met the Standard of Conduct, and without the necessity of any determination by the Determining Body as to whether Indemnitee has met the Standard of Conduct. In the event Indemnitee is not entirely successful on the merits or otherwise in defense of any Claim, but is successful on the merits or otherwise in defense of any claim, issue or matter involved in the Claim, Indemnitee shall be indemnified for the portion of Indemnitee’s Expenses incurred in such successful defense that is determined by the Determining Body (or by Special Counsel in the case of a Claim described in clause (a)(z) of this Section 10.3) to be reasonably and properly allocable to the claims, issues, or matters as to which Indemnitee was successful.
(e)Except as otherwise provided in Section 10.3(d), the Corporation shall not indemnify any Indemnitee under Section 10.3(a) unless a determination has been made by the Determining Body (or by a court upon application or in a proceeding brought by Indemnitee under Section 10.4) with respect to a specific Claim that indemnification of Indemnitee is permissible because Indemnitee has met the Standard of Conduct. In the event settlement of a Claim to which Indemnitee is a party has been proposed (“Proposed Settlement”), the Determining Body shall, promptly after submission to it but prior to consummation of the Proposed Settlement, make a determination whether Indemnitee shall have met the Standard of Conduct. In the event such determination is adverse to Indemnitee, Indemnitee shall be entitled to reject the Proposed Settlement. In the event of final disposition of a Claim other than by settlement, the Determining Body shall, promptly after but not before such final disposition, make a determination whether Indemnitee has met the Standard of Conduct. In all cases, the determination shall be in writing and shall set forth in reasonable detail the basis and reasons therefor. The Determining Body shall, promptly after making such determination, provide a copy thereof to both the Disbursing Officer and Indemnitee and shall instruct the former either to (i) reimburse Indemnitee as soon as practicable for all Expenses, if any, to which Indemnitee has been so determined to be entitled and which have not previously been advanced to Indemnitee under Section 10.2 (or otherwise recovered by Indemnitee through an insurance or other arrangement provided by the Corporation), or (ii) seek reimbursement from Indemnitee (subject to Indemnitee's rights under Section 10.4) of all advancements that have been made pursuant to Section 10.2 as to which it has been so determined that Indemnitee is not entitled to be indemnified.
(f)Indemnitee shall cooperate with the Determining Body at the expense of the Corporation by providing to the Determining Body, upon reasonable advance request, any documentation or information that is not privileged or otherwise protected from
    10


disclosure and that is reasonably available to Indemnitee and reasonably necessary to enable the Determining Body to discharge its responsibilities under this Section 10.3.
(g)If the Determining Body makes a determination pursuant to Section 10.3(e) that Indemnitee is entitled to indemnification, the Corporation shall be bound by that determination in any judicial proceeding, absent a determination by a court that such indemnification contravenes applicable law.
(h)In making a determination under Section 10.3(e), the Determining Body shall presume that the Standard of Conduct has been met unless the contrary shall be established by a preponderance of the evidence.
(i)The Corporation and Indemnitee shall keep confidential, to the extent permitted by law and their fiduciary obligations, all facts and determinations provided pursuant to or arising out of the operation of this Section, and the Corporation and Indemnitee shall instruct their respective agents to do likewise.
10.4Enforcement.
(a)The rights provided by this Section 10 shall be enforceable by Indemnitee in any court of competent jurisdiction.
(b)If Indemnitee seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Section 10, Indemnitee shall be entitled to recover from the Corporation, and shall be indemnified by the Corporation against, any and all Expenses incurred by Indemnitee in connection with such proceeding, but only if Indemnitee prevails therein. If it shall be determined that Indemnitee is entitled to receive part but not all of the relief sought, then Indemnitee shall be entitled to be reimbursed for all Expenses incurred by Indemnitee in connection with such judicial adjudication if the indemnification amount to which Indemnitee is determined to be entitled exceeds 50% of the amount of Indemnitee’s claim. Otherwise, the reimbursement of Expenses incurred by Indemnitee in connection with such judicial adjudication shall be appropriately prorated.
(c)In any judicial adjudication described in this Section 10.4, it shall be presumed that Indemnitee is entitled to the advancement or reimbursement of Expenses sought with respect to any Claim unless the Corporation shall establish the contrary by a preponderance of the evidence.
10.5Saving Clause.
(a)If any provision of this Section 10 is determined by a court having jurisdiction over the matter to require the Corporation to do or refrain from doing any act that is in violation of applicable law, the court shall be empowered to modify or reform such provision so that, as modified or reformed, such provision provides the maximum indemnification permitted by law and such provision, as so modified or reformed, and the balance of this Section 10, shall be applied in accordance with their terms. Without limiting the generality of the foregoing, if any portion of this Section 10 shall be invalidated on any ground, the Corporation shall nevertheless indemnify Indemnitee to the full extent permitted by any applicable portion of this Section 10 that shall not have been invalidated and to the full extent permitted by law with respect to that portion that has been invalidated.
    11


(b)The terms and conditions of this Section 10 supersede and replace in their entirety, as of February 24, 2016, the terms and conditions of Section 10 of Article II of these Bylaws in effect prior to such date (the “Old Indemnification Bylaw”) under which the Corporation agreed to indemnify the Indemnitees with respect to certain matters in a manner generally similar to this Section 10. Each Indemnitee shall remain entitled after February 24, 2016 to all rights and remedies accrued or acquired under the Old Indemnification Bylaw prior to such date. In the event of any conflict between this Section 10 and the Old Indemnification Bylaw, this Section 10 shall control, except that, to the greatest extent permitted by applicable law, the Corporation shall treat all Indemnitee requests for advancement or indemnification made after such date based on Claims, acts, omissions, or conduct that occurred prior to such date in the manner most favorable to Indemnitee under either this Section 10 or the Old Indemnification Bylaw, as the case may be.
10.6Non-Exclusivity. The indemnification and payment of Expenses provided by or granted pursuant to this Section 10 shall not be deemed exclusive of any other rights to which Indemnitee is or may become entitled under any statute, article of incorporation, insurance policy, authorization of shareholders or directors, agreement or otherwise, including, without limitation, any rights authorized by the Determining Body in its discretion with respect to matters for which indemnification is permitted under LBCA Section 1-851.
10.7Subrogation. In the event of any payment under this Section 10, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee. Following receipt of indemnification payments hereunder, as further assurance, Indemnitee shall execute all papers reasonably required and, at the expense of the Corporation, take all action reasonably necessary to secure such subrogation rights, including execution of such documents as are reasonably necessary to enable the Corporation to bring suit to enforce such rights.
10.8Successors and Assigns.
(a)The Corporation shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all the business or assets of the Corporation, by agreement or other instrument in form and substance satisfactory to the Corporation, expressly to assume and agree to perform its obligations under this Section 10 in the same manner and to the same extent the Corporation would be required to perform if no such succession had taken place.
(b)Indemnitee’s right to advancement and indemnification of Expenses pursuant to this Section 10 shall continue regardless of the termination of Indemnitee’s status as a director or officer of the Corporation, and this Section 10 shall inure to the benefit of and be enforceable by Indemnitee’s personal or legal representatives, executors, administrators, spouses, heirs, assigns and other successors.
(c)The rights granted to each Indemnitee under this Section 10 are personal in nature and neither the Corporation nor any Indemnitee shall, without the prior written consent of the other, assign or delegate any rights or obligations under this Section 10 except as expressly provided in Sections 10.8(a) and 10.8(b).
(d)This Section 10 shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation, reorganization or otherwise to all or substantially all of the business or assets of the Corporation), permitted, assigns, spouses, heirs, executors, administrators and personal and legal representatives.

5.3Proxy Access Rights.
(a)Whenever the Corporation solicits proxies with respect to an election of directors at an annual meeting, the Corporation shall, subject to the terms and conditions of this Section 5.3, (i) include in its proxy statement for the annual meeting the name, together with the Required Information (as defined below), of any person nominated for election (each such person being hereinafter referred to as a “Shareholder Nominee”) to the Board of Directors by a shareholder that satisfies, or by a group of no more than ten shareholders that satisfy, the requirements of this Section 5.3 (such individual or group, including as the context requires each member thereof, being hereinafter referred to as the “Eligible Shareholder”) and all applicable laws, and who expressly elects at the time of providing the notice required by Section 5.3(g) of this Bylaw to have its nominee or nominees included in the Corporation’s proxy materials pursuant to this Section 5.3 and (ii) permit the Corporation’s shareholders to vote upon each such Shareholder Nominee, in addition to individuals nominated by the Board of Directors, in connection with such meeting. Such notice shall consist of a copy of Schedule 14N duly filed with the U.S. Securities and Exchange Commission in accordance with Rule 14a-18 promulgated under the Exchange Act and the information required to be delivered to the Corporation by this Section 5.3 (all such information collectively being hereinafter referred to as the “Section 5.3 Notice”), and such notice shall be delivered to the Corporation in accordance with the procedures and during the time period set forth in Section 5.3(g) of this Bylaw.
(b)For purposes of Section 5.3(a) of this Bylaw, the “Required Information” that the Corporation will include in its proxy statement is (i) the information concerning the Shareholder Nominee and the Eligible Shareholder that is required to be disclosed in the Corporation’s proxy statement by the regulations promulgated under the Exchange Act, by these Bylaws, by the Articles of Incorporation or by the Listing Standards (as
    21


defined below); and (ii) if the Eligible Shareholder so elects, a Statement (as defined below).
(c)The number of Shareholder Nominees (including Shareholder Nominees that were submitted by an Eligible Shareholder for inclusion in the Corporation’s proxy materials pursuant to this Section 5.3 but either are subsequently withdrawn or that the Board of Directors decides to nominate as Board of Director nominees) appearing in the Corporation’s proxy materials with respect to an annual meeting shall not exceed 20% of the number of directors in office as of the last day on which a Section 5.3 Notice of a nomination may be timely delivered pursuant to Section 5.3(g) of this Bylaw, or if such amount is not a whole number, the closest whole number below 20%.

In the event that the number of Shareholder Nominees submitted by Eligible Shareholders pursuant to this Section 5.3 exceeds this maximum number, each Eligible Shareholder will select one Shareholder Nominee for inclusion in the Corporation’s proxy materials until the maximum number is reached, selecting in order from the largest to the smallest of such shareholders based upon the number of shares of common stock of the Corporation each Eligible Shareholder disclosed as owned in the Section 5.3 Notice submitted to the Corporation hereunder. If the maximum number is not reached after each Eligible Shareholder has selected one Shareholder Nominee, this selection process will continue as many times as necessary, following the same order each time, until the maximum number is reached.
(d)In order to make a nomination pursuant to this Section 5.3, an Eligible Shareholder must have owned (as defined below) 3% or more of the Corporation’s outstanding common stock continuously for at least three years (the “Required Shares”) as of both the date the Section 5.3 Notice of the nomination is furnished in accordance with Section 5.3(g) of this Bylaw and the record date for determining shareholders entitled to vote at the annual meeting, and must continue to own the Required Shares through the applicable meeting date. To be in proper form and effective for purposes of this Section 5.3, a Section 5.3 Notice furnished to the Secretary of the Corporation must:

(iv)include a written undertaking (in the form provided by the Secretary of the Corporation upon written request) that the Eligible Shareholder agrees to (A) assume all liability stemming from any legal or regulatory violation arising out of the communications with shareholders of the Corporation by the Eligible Shareholder, its affiliates and associates, or their respective agents or representatives, either before or after the furnishing of the Section 5.3 Notice, or out of the information that the Eligible Shareholder has provided or will provide to the Corporation or filed or to be filed with the U.S. Securities and Exchange Commission, including an agreement to indemnify the Corporation and its agents and representatives in respect of any such liabilities, (B) comply with all other laws and regulations applicable to any solicitation in connection with the annual meeting, including without limitation Rule 14a-9 and Rule 14a-18 promulgated under the Exchange Act, and (C) provide to the Corporation promptly, and in no event more than five business days after it has been requested, such additional information as requested pursuant to this Section 5.3 or any other subsection of this Section 5 of these Bylaws; and
    23

(e)Notwithstanding anything in these Bylaws to the contrary, the Corporation shall not be required to include, pursuant to this Section 5.3, any nominee information in its proxy materials (i) with respect to any meeting of shareholders for which the Secretary of the Corporation receives a notice that the Eligible Shareholder or any other shareholder of the Corporation has nominated one or more persons for election to the Board of Directors pursuant to the advance notice requirements set forth in Section 5.1 of this Bylaw, (ii) concerning any Shareholder Nominee who (A) is not independent under the Independence Standards (as defined below in Section 5.4(d) of this Bylaw), as determined in good faith by the Board of Directors or one or more of its committees, (B) provides any information to the Corporation or its shareholders required or requested pursuant to any subsection of this Section 5 of these Bylaws that is not accurate, truthful and complete in all material respects, or that otherwise contravenes any of the agreements or representations made by the Shareholder Nominee in connection with the nomination, (C) has been an officer or director of a competitor, as defined in Section 8 of the Clayton Antitrust Act of 1914, within the past three years, (D) is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses) or has been convicted in such a criminal proceeding within the past ten years or (E) is subject to any order of the type specified in Rule 506(d) of Regulation D promulgated under the Securities Act of 1933, as amended, or (iii) with respect to any request of any Eligible Shareholder who (A) provides any information to the Corporation or its shareholders required or requested pursuant to any subsection of this Section 5 of these Bylaws that is not accurate, truthful and complete in all material respects or (B) otherwise fails, or nominates any Shareholder Nominee who fails, to comply with its obligations pursuant to any subsection of this Section 5 of these Bylaws.
(f)The Eligible Shareholder may, at its option, provide to the Secretary of the Corporation, at the time the information required by this Section 5.3 is provided, a written statement for inclusion in the Corporation’s proxy statement for the annual meeting, not to exceed 500 words, in support of the Shareholder Nominee’s candidacy (the “Statement”). Notwithstanding anything to the contrary contained in this Section 5.3, the Corporation may omit from its proxy materials any information or Statement that it, in good faith, believes is materially false or misleading, omits to state any material fact, or would violate any applicable law or regulation.
(g)Notwithstanding the procedures set forth in Section 5.1 or 5.2 of this Bylaw, any Section 5.3 Notice, to be timely under this Section 5.3, must be received by the Secretary of the Corporation at the principal executive office of the Corporation within the time period applicable to notices of shareholder proposals made at annual meetings pursuant to Rule 14a-8 promulgated under the Exchange Act.
(h)For purposes of this Section 5.3, an Eligible Shareholder shall be deemed to “own” only those outstanding shares of common stock of the Corporation as to which the shareholder possesses both (i) the full voting and investment rights pertaining to the shares and (ii) the full economic interest in (including the opportunity for profit and risk of loss on) such shares; provided that the number of shares calculated in accordance with clauses (i) and (ii) shall not include any shares (x) sold by such shareholder or any of its affiliates in any transaction that has not been settled or closed, (y) borrowed by such shareholder or any of its affiliates for any purposes or purchased by such shareholder or any of its affiliates pursuant to an agreement to resell or (z) subject to any option, warrant, forward contract, swap, contract of sale, other derivative or similar agreement
    24


entered into by such shareholder or any of its affiliates, whether any such instrument or agreement is to be settled with shares or with cash based on the notional amount or value of shares of outstanding common stock of the Corporation, if, in any such case, such instrument or agreement has, or is intended to have, the purpose or effect of (1) reducing in any manner, to any extent or at any time in the future, such shareholder’s or affiliates’ full right to vote or direct the voting of any such shares or (2) hedging, offsetting or altering to any degree gain or loss arising from the full economic ownership of such shares by such shareholder or affiliate. For purposes of this Section 5.3, a shareholder shall “own” shares held in the name of a nominee or other intermediary so long as the shareholder retains the right to instruct how the shares are voted with respect to the election of directors and possesses the full economic interest in the shares. A shareholder’s ownership of shares shall be deemed to continue during any period in which the shareholder has delegated any voting power by means of a proxy, power of attorney or other instrument or arrangement which is revocable at any time by the shareholder. The terms “owned,” “owning” and other variations of the word “own” shall have correlative meanings. Whether outstanding shares of the common stock of the Corporation are “owned” for these purposes shall be determined in good faith by the Board of Directors.

No person may be a member of more than one group of persons constituting an Eligible Shareholder with respect to any annual meeting.
(j)Any Shareholder Nominee who is included in the Corporation’s proxy materials for a particular annual meeting of shareholders but either (i) withdraws from or becomes ineligible or unavailable for election at the annual meeting or (ii) does not receive at least 25% of the votes cast in favor of the Shareholder Nominee’s election will be ineligible to be a Shareholder Nominee pursuant to this Section 5.3 for the next two annual meetings.
(k)Except for a nomination made in accordance with Rule 14a-19 of the Exchange Act, this Section 5.3 provides the exclusive method for shareholders (including any beneficial owner) to include nominees for Director in the Corporation’s proxy materials.
5.4Other Related Provisions.
(a)Subject to Section 5.4(c) of this Bylaw, only such persons who are nominated in accordance with the procedures set forth in this Section 5 of these Bylaws shall be eligible to be elected at a meeting of shareholders to serve as Directors and only such business shall be conducted at a meeting of shareholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 5 of these Bylaws.

(b)Notwithstanding the foregoing provisions of this Section 5 of these Bylaws, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder with respect to the matters set forth in this Section 5; provided, however, that any references in these Bylaws to the Exchange Act or the rules promulgated thereunder are not intended to and shall not limit the requirements applicable to nominations or proposals as to any other business to be considered pursuant to Section 5.1(a)(iii), Section 5.2(b)(ii) or Section 5.3 of this Bylaw.
(c)Except for proposals properly made in accordance with Rule 14a-8 promulgated under the Exchange Act and included in the notice of meeting duly given by or at the direction of the Board of Directors or any duly authorized committee thereof under this Section 5 of these Bylaws, compliance with Section 5.1(a)(iii), Section 5.2(b)(ii) and Section 5.3 shall be the exclusive means for a shareholder to bring matters before an annual meeting of shareholders or a special meeting of shareholders, respectively.

Except as otherwise expressly provided to the contrary in Rule 14a-8 or Rule 14a-19 promulgated under the Exchange Act or Section 5.3 of this Bylaw, nothing in these Bylaws shall be construed to permit any shareholder, or give any shareholder the right, to include or have disseminated or described in the Company’s proxy materials any director nominations or any other proposal.

(e)The right of any shareholder to make any nominations or proposals under any subsection of this Section 5 of these Bylaws is subject to the condition that the shareholder of record deliver (in accordance with the time limits prescribed for delivery of notice under the applicable subsection of this Section 5 of these Bylaws) to the Secretary of the Corporation at the principal executive office of the Corporation a written representation that either such record shareholder or the beneficial owner, if any, on whose behalf the nomination or proposal is being made intends to attend the applicable meeting of shareholders to address any questions regarding the nomination or proposal and, in the event of any nomination or proposal made pursuant to Section 5.1 or 5.2 of this Bylaw, to propose such action at the meeting and a written acknowledgement that, if such shareholder does not appear to present such proposed business at such meeting, the Corporation need not present such proposed business for a vote at such meeting notwithstanding that proxies in respect of such vote may have been received by the Corporation.

Notwithstanding the foregoing, no update or supplement (including any notification as to a change in a shareholder’s intent to solicit proxies contemplated by Section 5) shall cure or affect (i) the accuracy (or inaccuracy) of any representations made by shareholder, any such beneficial owner or any of their associated parties or nominees or (ii) the validity (or invalidity) of any nomination or proposal that failed to comply with or is rendered invalid under this Section 5 or any other applicable provision of these Bylaws.
(g)For purposes of this Section 5 of these Bylaws, (i) “affiliate” and “associate” shall each have the respective meanings ascribed to them in Rule 405 promulgated under the Securities Act of 1933, as amended (including, when such terms are used in reference to any particular entity, all entities or natural persons that control such particular entity); provided, however, that with respect to any investment company (as defined in the Investment Company Act of 1940, as amended, whether or not exempt from registration thereunder), “affiliate” shall also include all other investment companies managed by the same investment adviser or any of its affiliates, (ii) “group” shall have the meaning ascribed to it in rules adopted by the U.S. Securities and Exchange Commission interpreting various provisions under Section 13 of the Exchange Act, (iii) “public announcement” shall mean disclosure in a press release reported by a national news service or in a document publicly filed by the Corporation with the U.S. Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act and the rules and regulations promulgated thereunder, and (iv) “Listing Standards” shall mean the rules and listing standards of the principal U.S. securities exchange upon which the Corporation’s common stock is listed.

Section 6.Quorum.
6.1    Establishment of Quorum.
(a)Except as otherwise provided by law, at all meetings of shareholders the presence, in person or by proxy, of the holders of a majority of the Total Voting Power shall constitute a quorum to organize the meeting. For purposes of determining the existence of a quorum to organize the meeting, shares of Voting Stock as to which the holders have voted or abstained from voting with respect to any matter considered at a meeting, or which are subject to Non-Votes (as defined in Section 6.3 below), shall be counted as present.
(b)With respect to each matter to be acted upon at any duly organized meeting of shareholders, the presence, in person or by proxy, of the holders of a majority of the Total Voting Power entitled to be cast on the matter shall constitute a quorum for action on that matter; provided, however, that this subsection shall not have the effect of reducing the vote required to approve any matter that may be established by law, the Articles of Incorporation or these Bylaws.
6.2Withdrawal. If a quorum is present or represented for purposes of organizing a duly convened meeting, such meeting may continue to do business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum, or the refusal of any shareholders present to vote.
6.3Non-Votes. As used in these Bylaws, “Non-Votes” shall mean the number of votes as to which the record holder or proxy holder of shares of Capital Stock has been precluded from voting thereon (whether by law, by regulations of the Securities and Exchange Commission, by rules, bylaws or listing standards of any national securities exchange or other self-regulatory organization, or otherwise), including without limitation votes as to which brokers may not or do not exercise discretionary voting power under the rules of the New York Stock Exchange.
Section 7.Voting Power Present or Cast.
For purposes of determining the amount of Total Voting Power present or represented or the amount of Total Voting Power actually cast at any annual or special meeting of shareholders with respect to voting on any particular matter, shares as to which the holders have abstained from voting, and shares which are subject to Non-Votes, will not be treated as present, represented or cast.
Section 8.Voting Requirements.
8.1General Voting Standard. If a quorum exists under Section 6.1(b), action on any matter, other than the election of directors, brought to the shareholders for their consideration, adoption or consent will be approved if the votes cast favoring the action exceed the votes cast opposing the action, unless the question is one upon which, by express provision of law, the Articles of Incorporation or Subsection 8.2 below, a different vote is required, in which case such express provision shall govern and control the decision of such question.
8.2Majority Director Election Standard. Subject to the rights of the holders of any series of preferred stock and except as otherwise required by law or the Articles of Incorporation, each director to be elected by the shareholders must receive a majority of the votes cast with respect to the election of that director at any meeting for the election of directors at which a
    29


quorum is present, provided that if the number of nominees exceeds the number of directors to be elected in a contested election, the directors will be elected by a plurality of the shares represented in person or by proxy at the meeting and entitled to vote on the election of directors. For purposes of this section, (i) a “majority of votes cast” means that the number of votes cast “for” a director’s election exceeds the number of votes cast as “withheld” or “against” with respect to that director’s election and (ii) a “contested election” means that the number of persons properly nominated to serve as directors of the Corporation exceeds the number of directors to be elected.
8.3Resignation Offers. If a director nominee who is an incumbent director is not elected and no successor has been elected at the same meeting, the director must submit to the Board of Directors promptly after the certification of the election results a letter offering to resign from the Board of Directors (a “Resignation Offer”). The Nominating and Corporate Governance Committee will consider the Resignation Offer and will make a recommendation to the Board of Directors whether to accept the Resignation Offer, reject the Resignation Offer or take other action. The Board of Directors, taking into account the Nominating and Corporate Governance Committee’s recommendation and any other factors they deem relevant, will act on each Resignation Offer within 90 days from the date of the certification of the election results and will disclose promptly in a Form 8-K Report filed with the Securities and Exchange Commission its decision and the rationale therefor.
Section 9.Proxies.
9.1Execution of Proxies. At any meeting of the shareholders, every shareholder having the right to vote shall be entitled to vote in person or by proxy appointed by an instrument in writing subscribed by such shareholder and bearing a date not more than 11 months prior to the meeting, unless the instrument provides for a longer period. The person appointed as proxy need not be a shareholder of the Corporation. Any shareholder directly or indirectly soliciting proxies from other shareholders must use a proxy card color other than white, which is reserved for the exclusive use by the Board of Directors.
9.2Electronically Transmitted Proxies. A shareholder may authorize another person or persons to act for him as proxy by delivering or authorizing the delivery of any form of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or similar agent duly authorized by the person who will be the holder of the proxy to receive such transmission; provided, however, that any such electronic transmission shall be submitted with information from which the Corporation may determine that the electronic transmission was authorized by the shareholder. If it is determined that such electronic transmissions are valid, the inspectors or other persons making that determination shall specify the information upon which they relied.
Section 10.Postponements, Adjournments, or Cancellations of Meetings.
10.1Postponements and Adjournments of Meetings. In accordance with the provisions of applicable law, the Board of Directors, acting by resolution, may postpone and reschedule any previously scheduled meeting of shareholders, whether annual or special. In addition, any meeting of shareholders, whether annual or special, may be adjourned from time to time either by the chairman of the meeting or by the shareholders upon attaining the vote specified in Section 8.1 of this Article IV. When a meeting is adjourned to another time or place, if any, notice need not be given of the adjourned meeting if the time and place, if any, thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if after the adjournment a new record date is fixed
    30

(b)The term “Claim” shall mean any threatened, pending or concluded claim, action, suit, or proceeding, including discovery, whether civil, criminal, administrative, arbitrative or investigative and whether made judicially or extra-judicially, or involving



Indemnitee solely as a witness or person required to give evidence, or any separate issue or matter therein, as the context requires, but shall not include any action, suit or proceeding initiated by Indemnitee against the Corporation (other than to enforce the terms of this Section), or initiated by Indemnitee against any director or officer of the Corporation unless the Corporation has joined in or consented in writing to the initiation of such action, suit or proceeding.
(c)The term “Determining Body” shall mean (i) if there are two or more qualified directors (as defined in Section 1-140(18B) of the LBCA), all of the qualified directors (“Disinterested Directors”), or (ii) special legal counsel (A) selected by the Disinterested Directors or (B) if there are fewer than two Disinterested Directors selected by the Board of Directors (in which selection directors who do not qualify as Disinterested Directors may participate); provided, however, that following a Change of Control, with respect to all matters thereafter arising out of acts, omissions or events occurring prior to or after the Change of Control concerning the rights of Indemnitee to seek indemnification, such determination shall be made by special legal counsel selected by the Board of Directors in the manner described above in this Section 10.1(c) (which selection shall not be unreasonably delayed or withheld) from a panel of three counsel nominated by Indemnitee. Such counsel (“Special Counsel”) shall not have otherwise performed services for the Corporation, Indemnitee or their respective affiliates (other than services as special legal counsel in connection with similar matters) within the five years preceding its engagement. If Indemnitee fails to nominate Special Counsel within ten business days following written request by the Corporation, the Board of Directors shall select such counsel. Such counsel shall not be a person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Corporation or Indemnitee in an action to determine Indemnitee's rights under this Section 10, nor shall Special Counsel be any person who has been sanctioned or censured for ethical violations of applicable standards of professional conduct. The Corporation agrees to pay the reasonable fees and costs of the Special Counsel referred to above and to fully indemnify such Special Counsel against any and all expenses, claims, liabilities and damages arising out of or relating to this Section 10.1(c) or its engagement pursuant hereto. The Determining Body shall determine in accordance with Section 10.3 whether and to what extent Indemnitee is entitled to be indemnified under this Section and shall render a written opinion to the Corporation and to Indemnitee to such effect.
(d)The term “D&O Insurance” shall mean directors and officers liability insurance.
(e)The term "Disbursing Officer" shall mean, with respect to a Claim, the Chief Executive Officer of the Corporation or, if the Chief Executive Officer is a party to the Claim as to which advancement or indemnification is being sought, any officer who is not a party to the Claim and who is designated by the Chief Executive Officer, which designation shall be made promptly after the Corporation's receipt of Indemnitee's initial request for advancement or indemnification and communicated to Indemnitee.
(f)The term “Expenses” shall mean any reasonable expenses or costs (including, without limitation, attorney’s fees, fees of experts retained by attorneys, judgments, punitive or exemplary damages, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee with respect to a Claim, except that Expenses shall not include any amount paid in settlement of a Claim against Indemnitee (i) by or in the right of the Corporation, or (ii) that the Corporation has not approved, which approval will not be unreasonably delayed or withheld.



(g)The term “Indemnitee” shall mean each Director and officer and each former Director and officer of the Corporation.
(h)The term “Section” or “Section 10” shall mean Article II, Section 10, of these Bylaws, in its entirety, unless the context otherwise provides.
(i)The term “Standard of Conduct” shall mean conduct by an Indemnitee with respect to which a Claim is asserted that was in good faith and that Indemnitee reasonably believed to be in, or (in the case of conduct other than in an official capacity) not opposed to, the best interest of the Corporation, and, in the case of a Claim that is a criminal action or proceeding, conduct that the Indemnitee had no reasonable cause to believe was unlawful. The termination of any Claim by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not meet the Standard of Conduct.
10.2Advancement of Expenses.
(a)Subject to Indemnitee’s furnishing the Corporation with (i) a written undertaking, in a form reasonably satisfactory to the Corporation, to repay such amount if it is ultimately determined that Indemnitee is not entitled under this Section 10 to indemnification therefor and (ii) a written affirmation meeting the requirements of LBCA Section 1-853(A)(1), the Corporation shall advance Expenses to Indemnitee in advance of the final disposition of any Claim involving Indemnitee; provided, however, that Indemnitee will return, without interest, any such advance that remains unspent immediately following resolution of the Claim to which the advance related, and provided further, that advances of such Expenses by the Corporation's D&O Insurance carrier shall be treated, for purposes of this Section 10.2(a), as advances by the Corporation. The written undertaking by Indemnitee must be an unlimited general obligation of Indemnitee but need not be secured and will be accepted by the Corporation without reference to the financial ability of Indemnitee to make repayment.
(b)Any request for advancement of Expenses shall be submitted by Indemnitee to the Disbursing Officer in writing and shall be accompanied by a written description of the Expenses for which advancement is requested. The Disbursing Officer shall, within 30 days after receipt of Indemnitee's request for advancement, advance such Expenses unsecured, interest-free and without regard to Indemnitee's ability to make repayment, provided that if the Disbursing Officer questions the reasonableness of any such request, that officer shall promptly advance to the Indemnitee the amount deemed by that officer to be reasonable and shall forward immediately to the Board of Directors a copy of the Indemnitee's request and of the Disbursing Officer’s response, together with a written description of that officer’s reasons for questioning the reasonableness of a portion of the advancement sought. The Board of Directors shall, within 30 days after receiving such a request from the Disbursing Officer, determine the reasonableness of the disputed Expenses and notify Indemnitee and the Disbursing Officer of its decision, which shall be final, subject to Indemnitee’s right under Section 10.4 to seek a judicial adjudication of Indemnitee’s rights. The determination shall be made, if there are two or more Disinterested Directors, by the majority vote of the Disinterested Directors, or otherwise by a majority vote of all directors including those who are not Disinterested Directors.
(c)Indemnitee's right to advancement under this Section 10.2 shall include the right to advancement of Expenses incurred by Indemnitee in a suit against the Corporation under Section 10.4 to enforce Indemnitee's rights under this Section. Such right of advancement shall, however, be subject to Indemnitee's obligation pursuant to



Indemnitee’s undertaking described in Section 10.2(a) to repay such advances, to the extent provided in Section 10.4, if it is ultimately determined in the enforcement suit that Indemnitee is not entitled to indemnification for a Claim.
10.3Indemnity.
(a)The Corporation shall, in the manner provided in this Section, indemnify and hold harmless Indemnitee against Expenses incurred in connection with any Claim against Indemnitee (whether as a subject of or party to, or a proposed or threatened subject of or party to, the Claim) or in which Indemnitee is involved solely as a witness or person required to give evidence, by reason of Indemnitee’s position: (A) as a director or officer of the Corporation, (B) as a director or officer of any subsidiary of the Corporation or as a fiduciary with respect to any employee benefit plan of the Corporation, or (C) as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other for profit or not for profit entity or enterprise, if such position is or was held at the request of the Corporation, regardless of when serving in any such position occurred, if (x) Indemnitee is successful in defense of the Claim on the merits or otherwise, as provided in Section 10.3(d), (y) Indemnitee has been found by the Determining Body to have met the Standard of Conduct or (z) Indemnitee has been determined in writing by Special Counsel to have engaged in conduct for which broader indemnification has been made permissible under the Articles of Incorporation for which liability has been eliminated under (or pursuant to) LBCA Section 1-832; provided that no indemnification shall be made in respect of any Claim by or in the right of the Corporation as to which Indemnitee shall have been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable on the basis of receiving a financial benefit to which the Indemnitee was not entitled unless, and only to the extent, a court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as the court shall deem proper, and provided further, that Expenses incurred in connection with a Claim for which Indemnitee has been reimbursed or indemnified by the Corporation’s D&O Insurance carrier shall be credited against the Corporation’s obligation under this Section 10.3(a) with respect to such Claim.
(b)Promptly upon becoming aware of the existence of any Claim with respect to which Indemnitee may seek indemnification hereunder, Indemnitee shall notify the Chief Executive Officer (or, if the Chief Executive Officer is the Indemnitee, the next ranking executive officer who is not an Indemnitee with respect to the Claim) of the existence of the Claim, who shall promptly advise the Board of Directors that establishing the Determining Body will be a matter presented at the next regularly scheduled meeting of the Board of Directors. Failure or delay by Indemnitee in giving such notice shall not excuse performance by the Corporation hereunder except to the extent that, the Corporation did not otherwise learn of the Claim and such failure or delay results in forfeiture by the Corporation of substantial defenses, rights or insurance coverage. After the Determining Body has been established, the Chief Executive Officer or that officer’s delegate shall inform Indemnitee thereof and Indemnitee shall promptly notify the Determining Body, to the extent requested by it, of all facts relevant to the Claim known to Indemnitee.
(c)Indemnitee shall be entitled to conduct the defense of the Claim and to make all decisions with respect thereto, with counsel of Indemnitee’s choice, provided that in the event the defense of the Claim has been assumed by the Corporation through its D&O Insurance carrier or otherwise, then (i) Indemnitee will be entitled to retain



separate counsel from the Corporation’s Counsel (but not more than one law firm plus, if applicable, local counsel at the Corporation’s expense if, but only if, Indemnitee shall reasonably conclude that one or more legal defenses may be available to Indemnitee that are different from, or in addition to, those available to the Corporation or other defendants represented by the Corporation through its D&O Insurance carrier or otherwise, and (ii) the Corporation will not, without the prior written consent of Indemnitee, effect any settlement of the Claim unless such settlement (x) includes an unconditional release of Indemnitee from all liability that is the subject matter of such Claim, (y) does not impose penalties or post-settlement obligations on Indemnitee (except for customary confidentiality obligations), and (z) does not require payment by Indemnitee of money in settlement.
(d)To the extent (i) Indemnitee is successful on the merits or otherwise in defense of any Claim or (ii) Special Counsel has made the written determination described in clause (a)(z) of this Section 10.3, Indemnitee shall be indemnified against Expenses incurred by Indemnitee with respect to the Claim, regardless of whether Indemnitee has met the Standard of Conduct, and without the necessity of any determination by the Determining Body as to whether Indemnitee has met the Standard of Conduct. In the event Indemnitee is not entirely successful on the merits or otherwise in defense of any Claim, but is successful on the merits or otherwise in defense of any claim, issue or matter involved in the Claim, Indemnitee shall be indemnified for the portion of Indemnitee’s Expenses incurred in such successful defense that is determined by the Determining Body (or by Special Counsel in the case of a Claim described in clause (a)(z) of this Section 10.3) to be reasonably and properly allocable to the claims, issues, or matters as to which Indemnitee was successful.
(e)Except as otherwise provided in Section 10.3(d), the Corporation shall not indemnify any Indemnitee under Section 10.3(a) unless a determination has been made by the Determining Body (or by a court upon application or in a proceeding brought by Indemnitee under Section 10.4) with respect to a specific Claim that indemnification of Indemnitee is permissible because Indemnitee has met the Standard of Conduct. In the event settlement of a Claim to which Indemnitee is a party has been proposed (“Proposed Settlement”), the Determining Body shall, promptly after submission to it but prior to consummation of the Proposed Settlement, make a determination whether Indemnitee shall have met the Standard of Conduct. In the event such determination is adverse to Indemnitee, Indemnitee shall be entitled to reject the Proposed Settlement. In the event of final disposition of a Claim other than by settlement, the Determining Body shall, promptly after but not before such final disposition, make a determination whether Indemnitee has met the Standard of Conduct. In all cases, the determination shall be in writing and shall set forth in reasonable detail the basis and reasons therefor. The Determining Body shall, promptly after making such determination, provide a copy thereof to both the Disbursing Officer and Indemnitee and shall instruct the former either to (i) reimburse Indemnitee as soon as practicable for all Expenses, if any, to which Indemnitee has been so determined to be entitled and which have not previously been advanced to Indemnitee under Section 10.2 (or otherwise recovered by Indemnitee through an insurance or other arrangement provided by the Corporation), or (ii) seek reimbursement from Indemnitee (subject to Indemnitee's rights under Section 10.4) of all advancements that have been made pursuant to Section 10.2 as to which it has been so determined that Indemnitee is not entitled to be indemnified.
(f)Indemnitee shall cooperate with the Determining Body at the expense of the Corporation by providing to the Determining Body, upon reasonable advance request, any documentation or information that is not privileged or otherwise protected from



disclosure and that is reasonably available to Indemnitee and reasonably necessary to enable the Determining Body to discharge its responsibilities under this Section 10.3.
(g)If the Determining Body makes a determination pursuant to Section 10.3(e) that Indemnitee is entitled to indemnification, the Corporation shall be bound by that determination in any judicial proceeding, absent a determination by a court that such indemnification contravenes applicable law.
(h)In making a determination under Section 10.3(e), the Determining Body shall presume that the Standard of Conduct has been met unless the contrary shall be established by a preponderance of the evidence.
(i)The Corporation and Indemnitee shall keep confidential, to the extent permitted by law and their fiduciary obligations, all facts and determinations provided pursuant to or arising out of the operation of this Section, and the Corporation and Indemnitee shall instruct their respective agents to do likewise.
10.4Enforcement.
(a)The rights provided by this Section 10 shall be enforceable by Indemnitee in any court of competent jurisdiction.
(b)If Indemnitee seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Section 10, Indemnitee shall be entitled to recover from the Corporation, and shall be indemnified by the Corporation against, any and all Expenses incurred by Indemnitee in connection with such proceeding, but only if Indemnitee prevails therein. If it shall be determined that Indemnitee is entitled to receive part but not all of the relief sought, then Indemnitee shall be entitled to be reimbursed for all Expenses incurred by Indemnitee in connection with such judicial adjudication if the indemnification amount to which Indemnitee is determined to be entitled exceeds 50% of the amount of Indemnitee’s claim. Otherwise, the reimbursement of Expenses incurred by Indemnitee in connection with such judicial adjudication shall be appropriately prorated.
(c)In any judicial adjudication described in this Section 10.4, it shall be presumed that Indemnitee is entitled to the advancement or reimbursement of Expenses sought with respect to any Claim unless the Corporation shall establish the contrary by a preponderance of the evidence.
10.5Saving Clause.
(a)If any provision of this Section 10 is determined by a court having jurisdiction over the matter to require the Corporation to do or refrain from doing any act that is in violation of applicable law, the court shall be empowered to modify or reform such provision so that, as modified or reformed, such provision provides the maximum indemnification permitted by law and such provision, as so modified or reformed, and the balance of this Section 10, shall be applied in accordance with their terms. Without limiting the generality of the foregoing, if any portion of this Section 10 shall be invalidated on any ground, the Corporation shall nevertheless indemnify Indemnitee to the full extent permitted by any applicable portion of this Section 10 that shall not have been invalidated and to the full extent permitted by law with respect to that portion that has been invalidated.



(b)The terms and conditions of this Section 10 supersede and replace in their entirety, as of February 24, 2016, the terms and conditions of Section 10 of Article II of these Bylaws in effect prior to such date (the “Old Indemnification Bylaw”) under which the Corporation agreed to indemnify the Indemnitees with respect to certain matters in a manner generally similar to this Section 10. Each Indemnitee shall remain entitled after February 24, 2016 to all rights and remedies accrued or acquired under the Old Indemnification Bylaw prior to such date. In the event of any conflict between this Section 10 and the Old Indemnification Bylaw, this Section 10 shall control, except that, to the greatest extent permitted by applicable law, the Corporation shall treat all Indemnitee requests for advancement or indemnification made after such date based on Claims, acts, omissions, or conduct that occurred prior to such date in the manner most favorable to Indemnitee under either this Section 10 or the Old Indemnification Bylaw, as the case may be.
10.6Non-Exclusivity. The indemnification and payment of Expenses provided by or granted pursuant to this Section 10 shall not be deemed exclusive of any other rights to which Indemnitee is or may become entitled under any statute, article of incorporation, insurance policy, authorization of shareholders or directors, agreement or otherwise, including, without limitation, any rights authorized by the Determining Body in its discretion with respect to matters for which indemnification is permitted under LBCA Section 1-851.
10.7Subrogation. In the event of any payment under this Section 10, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee. Following receipt of indemnification payments hereunder, as further assurance, Indemnitee shall execute all papers reasonably required and, at the expense of the Corporation, take all action reasonably necessary to secure such subrogation rights, including execution of such documents as are reasonably necessary to enable the Corporation to bring suit to enforce such rights.
10.8Successors and Assigns.
(a)The Corporation shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all the business or assets of the Corporation, by agreement or other instrument in form and substance satisfactory to the Corporation, expressly to assume and agree to perform its obligations under this Section 10 in the same manner and to the same extent the Corporation would be required to perform if no such succession had taken place.
(b)Indemnitee’s right to advancement and indemnification of Expenses pursuant to this Section 10 shall continue regardless of the termination of Indemnitee’s status as a director or officer of the Corporation, and this Section 10 shall inure to the benefit of and be enforceable by Indemnitee’s personal or legal representatives, executors, administrators, spouses, heirs, assigns and other successors.
(c)The rights granted to each Indemnitee under this Section 10 are personal in nature and neither the Corporation nor any Indemnitee shall, without the prior written consent of the other, assign or delegate any rights or obligations under this Section 10 except as expressly provided in Sections 10.8(a) and 10.8(b).
(d)This Section 10 shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation, reorganization or otherwise to all or substantially all of the business or assets of the Corporation), permitted, assigns, spouses, heirs, executors, administrators and personal and legal representatives.



10.910.9 Indemnification of Other Persons. The Corporation may indemnify any person not a Director or officer of the Corporation to the extent authorized by the Board of Directors or a committee of the Board expressly authorized by the Board of Directors.
Section 11.Certain Qualifications.
(a)No person shall be eligible for nomination, election or service as a Director of the Corporation who shall (i) in the opinion of the Board of Directors fail to respond satisfactorily to the Corporation respecting any inquiry of the Corporation for information to enable the Corporation to make any certification required by the Federal Communications Commission under the Anti-Drug Abuse Act of 1988 or to determine the eligibility of such persons under this subsection; (ii) have been arrested or convicted of any offense concerning the distribution or possession of, or trafficking in, drugs or other controlled substances, provided that in the case of an arrest the Board of Directors may in its discretion determine that notwithstanding such arrest such persons shall remain eligible under this subsection; or (iii) have engaged in actions that could lead to such an arrest or conviction and that the Board of Directors determines would make it unwise for such person to serve as a Director of the Corporation.
(b)No person shall be eligible for nomination, election or service as a Director of the Corporation if the Board of Directors determines that (i) he or she failed to furnish any notice, undertaking, questionnaire, agreement or other instrument required to be delivered under any subsection of Section 5 of Article IV of these Bylaws or otherwise reasonably requested by the Corporation, all of which shall be provided promptly and in no event more than five business days after it has been requested, or (ii) in connection with furnishing any such notice, undertaking, questionnaire, agreement or other instrument, he or she failed to provide information that was true, correct and complete in all material respects or made an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made not misleading, including without limitation omitting to disclose any agreements, arrangements or understandings required to be disclosed in any such notice, undertaking, questionnaire, agreement or other instrument.
(c)Any person serving as a Director of the Corporation shall automatically cease to be a Director on such date as he or she ceases to have the qualifications set forth in this Section 11, and his or her position shall be considered vacant within the meaning of the Articles of Incorporation of the Corporation.
Section 12.Resignations.
A Director may resign at any time by providing written notice to the Board of Directors, the Chairman, the CEO or the Secretary.

Each such committee shall be comprised of such number of Directors as shall be set from time to

Any such subcommittee shall be composed solely of members of the committee, which shall appoint and replace such subcommittee members. Each subcommittee member shall hold office during the term designated by the committee, provided that such term shall automatically lapse if such member ceases to be a member of the committee or fails to meet any other qualifications that may be imposed by the committee.

committee or subcommittees. A majority of the members of any committee or subcommittee shall constitute a quorum and action by a majority (or by any super-majority required by the Governing Standards) of a quorum at any meeting of a committee or subcommittee shall be deemed action by the committee or subcommittee. The committee or subcommittee may also take action without meeting if all members thereof consent in writing thereto.

Such notice shall consist of a copy of Schedule 14N duly filed with the U.S. Securities and Exchange Commission in accordance with Rule 14a-18 promulgated under the Exchange Act and the information required to be delivered to the Corporation by this Section 5.3 (all such information collectively being hereinafter referred to as the “Section 5.3 Notice”), and such notice shall be delivered to the Corporation in accordance with the procedures and during the time period set forth in Section 5.3(g) of this Bylaw.

If the maximum number is not reached after each Eligible Shareholder has selected one Shareholder Nominee, this selection process will continue as many times as necessary, following the same order each time, until the maximum number is reached.

For purposes of this Section 5 of these Bylaws, any reference to delivery of notices or other written instruments to the Secretary of the Corporation at the principal office of the Corporation shall require such notice or other written instrument to be delivered by registered or certified mail, postage prepaid, to the Secretary at such office.

Section 6.Quorum.
6.1    Establishment of Quorum.
(a)Except as otherwise provided by law, at all meetings of shareholders the presence, in person or by proxy, of the holders of a majority of the Total Voting Power shall constitute a quorum to organize the meeting. For purposes of determining the existence of a quorum to organize the meeting, shares of Voting Stock as to which the holders have voted or abstained from voting with respect to any matter considered at a meeting, or which are subject to Non-Votes (as defined in Section 6.3 below), shall be counted as present.
(b)With respect to each matter to be acted upon at any duly organized meeting of shareholders, the presence, in person or by proxy, of the holders of a majority of the Total Voting Power entitled to be cast on the matter shall constitute a quorum for action on that matter; provided, however, that this subsection shall not have the effect of reducing the vote required to approve any matter that may be established by law, the Articles of Incorporation or these Bylaws.
6.2Withdrawal. If a quorum is present or represented for purposes of organizing a duly convened meeting, such meeting may continue to do business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum, or the refusal of any shareholders present to vote.
6.3Non-Votes. As used in these Bylaws, “Non-Votes” shall mean the number of votes as to which the record holder or proxy holder of shares of Capital Stock has been precluded from voting thereon (whether by law, by regulations of the Securities and Exchange Commission, by rules, bylaws or listing standards of any national securities exchange or other self-regulatory organization, or otherwise), including without limitation votes as to which brokers may not or do not exercise discretionary voting power under the rules of the New York Stock Exchange.
Section 7.Voting Power Present or Cast.
For purposes of determining the amount of Total Voting Power present or represented or the amount of Total Voting Power actually cast at any annual or special meeting of shareholders with respect to voting on any particular matter, shares as to which the holders have abstained from voting, and shares which are subject to Non-Votes, will not be treated as present, represented or cast.
Section 8.Voting Requirements.
8.1General Voting Standard. If a quorum exists under Section 6.1(b), action on any matter, other than the election of directors, brought to the shareholders for their consideration, adoption or consent will be approved if the votes cast favoring the action exceed the votes cast opposing the action, unless the question is one upon which, by express provision of law, the Articles of Incorporation or Subsection 8.2 below, a different vote is required, in which case such express provision shall govern and control the decision of such question.
8.2Majority Director Election Standard. Subject to the rights of the holders of any series of preferred stock and except as otherwise required by law or the Articles of Incorporation, each director to be elected by the shareholders must receive a majority of the votes cast with respect to the election of that director at any meeting for the election of directors at which a



quorum is present, provided that if the number of nominees exceeds the number of directors to be elected in a contested election, the directors will be elected by a plurality of the shares represented in person or by proxy at the meeting and entitled to vote on the election of directors. For purposes of this section, (i) a “majority of votes cast” means that the number of votes cast “for” a director’s election exceeds the number of votes cast as “withheld” or “against” with respect to that director’s election and (ii) a “contested election” means that the number of persons properly nominated to serve as directors of the Corporation exceeds the number of directors to be elected.
8.3Resignation Offers. If a director nominee who is an incumbent director is not elected and no successor has been elected at the same meeting, the director must submit to the Board of Directors promptly after the certification of the election results a letter offering to resign from the Board of Directors (a “Resignation Offer”). The Nominating and Corporate Governance Committee will consider the Resignation Offer and will make a recommendation to the Board of Directors whether to accept the Resignation Offer, reject the Resignation Offer or take other action. The Board of Directors, taking into account the Nominating and Corporate Governance Committee’s recommendation and any other factors they deem relevant, will act on each Resignation Offer within 90 days from the date of the certification of the election results and will disclose promptly in a Form 8-K Report filed with the Securities and Exchange Commission its decision and the rationale therefor.
Section 9.Proxies.
9.1Execution of Proxies. At any meeting of the shareholders, every shareholder having the right to vote shall be entitled to vote in person or by proxy appointed by an instrument in writing subscribed by such shareholder and bearing a date not more than 11 months prior to the meeting, unless the instrument provides for a longer period. The person appointed as proxy need not be a shareholder of the Corporation. Any shareholder directly or indirectly soliciting proxies from other shareholders must use a proxy card color other than white, which is reserved for the exclusive use by the Board of Directors.
9.2Electronically Transmitted Proxies. A shareholder may authorize another person or persons to act for him as proxy by delivering or authorizing the delivery of any form of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or similar agent duly authorized by the person who will be the holder of the proxy to receive such transmission; provided, however, that any such electronic transmission shall be submitted with information from which the Corporation may determine that the electronic transmission was authorized by the shareholder. If it is determined that such electronic transmissions are valid, the inspectors or other persons making that determination shall specify the information upon which they relied.
Section 10.Postponements, Adjournments, or Cancellations of Meetings.
10.1Postponements and Adjournments of Meetings. In accordance with the provisions of applicable law, the Board of Directors, acting by resolution, may postpone and reschedule any previously scheduled meeting of shareholders, whether annual or special. In addition, any meeting of shareholders, whether annual or special, may be adjourned from time to time either by the chairman of the meeting or by the vote of the holders of a majority of the Total Voting Power present in person or by proxy at the meetingshareholders upon attaining the vote specified in Section 8.1 of this Article IV. When a meeting is adjourned to another time or place, if any, notice need not be given of the adjourned meeting if the time and place, if any, thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if after the adjournment a



new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the meeting.
10.2Cancellations of Special Meetings. Unless provided otherwise by law or the Articles of Incorporation, any special meeting of the shareholders may be canceled, by resolution of the Board of Directors upon public notice given prior to the date previously scheduled for such special meeting or as otherwise permitted by the LBCA.
10.3Lack of Quorum. If a meeting cannot be organized because a quorum has not attended, those present may adjourn the meeting to such time and place as they may determine, subject, however, to the provisions of Section 10.1 hereof. In the case of any meeting called for the election of Directors, those who attend the second of such adjourned meetings, although less than a quorum as fixed in Section 6.1 of this Article, shall nevertheless constitute a quorum for the purpose of electing Directors.
Section 11.Written Consents.
Any action required or permitted to be taken at any annual or special meeting of shareholders may be taken only upon the vote of the shareholders, present in person or represented by duly authorized proxy, at an annual or special meeting duly noticed and called, as provided in these Bylaws, and may not be taken by a written consent of the shareholders pursuant to the LBCA.

Exhibit 4.1
DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

December 31, 2025

Lumen Technologies, Inc. (“Lumen”, the “Company”, “we” or “us”) has two classes of securities registered under Section 12 of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”): (i) Common Stock, no par value per share (“Common Stock”), and (ii) Series CC Junior Participating Preferred Stock Purchase Rights (“Purchase Rights”), both of which are listed on The New York Stock Exchange.

DESCRIPTION OF COMMON STOCK

The following is a summary description of the rights of the holders of the Common Stock and related provisions of the Company’s Articles of Incorporation, as amended and restated (the “Articles”), and bylaws, as amended and restated (the “Bylaws”), and applicable Louisiana law. This summary is intended to provide a general description only, does not purport to be complete and is qualified in its entirety by reference to, and should be read in conjunction with, the Articles, Bylaws and applicable Louisiana law.

General

As of December 31, 2025, Lumen was authorized under its Articles to issue an aggregate 2.202 billion shares of capital stock, consisting of 2.200 billion shares of Common Stock, no par value per share, and 2 million shares of preferred stock, $25.00 par value per share. All of the outstanding capital stock of the Company is fully paid and non-assessable.

Dividends

Holders of our Common Stock are entitled to receive dividends when, as and if declared by our board of directors, out of funds legally available therefor, subject to the preferences applicable to any outstanding preferred stock.

No Preemptive, Redemption or Conversion Rights

The Common Stock is not redeemable, is not subject to sinking fund provisions, does not have any conversion rights and is not subject to call. Holders of shares of Common Stock have no preemptive rights to maintain their percentage of ownership in future offerings or sales of stock of Lumen.

Voting Rights

Under the Articles, each share of Common Stock entitles the holder thereof to one vote per share in all elections of directors and on all other matters duly submitted to shareholders for their vote or consent. Holders of our Common Stock do not have cumulative voting rights.


#103495603v2


Liquidation, Dissolution or Similar Rights

In the event we liquidate, dissolve or wind up our affairs, holders of our Common Stock would be entitled to receive ratably all of our assets remaining after satisfying the preferences of our creditors and the holders of any outstanding preferred stock.

Certain Provisions Affecting Takeovers

Provisions of the Articles and Bylaws may delay or discourage transactions involving an actual or potential change of control in the Company or its management, including transactions in which shareholders might otherwise receive a premium for their shares, or transactions that the Company’s shareholders might otherwise deem to be in their best interests. Among other things:

Our Articles provide that shareholder action may only be taken at an annual or special meeting of shareholders and may not be taken by written consent of the shareholders.

Under our Articles, the shareholders may remove any director or the entire board of directors, only for cause, at any meeting of the shareholders called for such purpose, by the affirmative vote of (i) a majority of the total voting power of all shareholders and (ii) at any time there is a related person (as defined in the Articles), a majority of the total voting power of all shareholders other than the related person, voting as a separate group.

Pursuant to our Articles, vacancies on our board may be filled only by the board of directors by a vote of both a majority of the directors then in office and a majority of the continuing directors (as defined in the Articles) voting as a separate group.

Under our Articles, the number of authorized directors may not be increased or decreased without, among other things, the approval of both 80% of the directors then in office and a majority of the continuing directors voting as a separate group.

Our Articles contain “fair price” provisions designed to provide supermajority vote and other safeguards for our shareholders when related persons attempt to effect a business combination with us, unless the business combination is approved in advance by the directors or satisfies various minimum price, consideration and procedural requirements, in each case as set forth in the Articles.

Our board of directors is required by our Articles to consider particular factors enumerated therein when evaluating a business combination, tender or exchange offer or a proposal by another person to make a tender or exchange offer.

Our Bylaws establish an advance notice procedure with regard to the nomination, other than by or at the direction of our board of directors, of candidates for election as directors and with regard to other matters to be brought before a meeting of our shareholders.

Our Articles and applicable Louisiana law restrict the ability of the shareholders to call special shareholder’s meetings.

#103495603v2    2



Various provisions of our Articles may not be amended except upon the affirmative vote of both 80% of the total voting power of all shareholders and two-thirds of the total voting power of shareholders, other than a related person, present or represented at a shareholders’ meeting, voting as a separate group.

Our Bylaws may be adopted, amended or repealed and new bylaws may be adopted by either a majority of our directors and a majority of our continuing directors, voting as a separate group; or the holders of at least 80% of the total voting power of all shareholders and two-thirds of the total voting power of shareholders, other than a related person, present or duly represented at a shareholders’ meeting, voting as a separate group.

Our board of directors is authorized, without action of the shareholders, to issue (i) additional shares of Common Stock, subject to certain limitations under the New York Stock Exchange listing standards and the Louisiana Business Corporation Act, and (ii) additional shares of preferred stock with rights and preferences designated by the board of directors, which could include terms adversely affecting the rights of holders of the Common Stock.

In addition, certain federal foreign ownership limitations and provisions in our debt instruments could potentially discourage certain change of control transactions.

Additional Information

As of December 31, 2025, Lumen had outstanding 7,018 shares of 5% Cumulative Convertible Series L Preferred Stock that entitles the holders to certain preferential liquidation and other rights and to cast one vote per share, together with holders of the Common Stock, on all matters duly submitted to a vote of shareholders. For additional information on the matters summarized above, see our Registration Statement on Form 8-A/A filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 2, 2015. Our Articles and Bylaws are filed as exhibits to our accompanying Annual Report on Form 10-K.

On February 13, 2019, we entered into a Section 382 Rights Agreement (as amended and restated through the date hereof, the “NOL Rights Plan”) by and between the Company and Computershare, Inc., as rights agent (the “Rights Agent”). As previously disclosed, the Company and the Rights Agent amended this agreement on May 9, 2019 and November 20, 2020. On November 15, 2023, the Company and the Rights Agent entered into a Second Amended and Restated Section 382 Rights Agreement effective as of December 1, 2023 (the “2023 Amendment”).

We adopted the NOL Rights Plan to diminish the risk that we could experience an “ownership change” as defined under Section 382 of the Internal Revenue Code of 1986 (as amended, the “Code”), which could substantially limit our ability to use our net operating loss carryover (collectively, the “NOLs”) to reduce anticipated future tax liabilities. The 2023

#103495603v2    3


Amendment, among other things, (i) extended the NOL Rights Plan’s expiration date through December 1, 2026 to protect the Company’s NOLs and (ii) reduced the purchase price from $28 to $9 per one ten-thousandth of a Preferred Share (as defined below).

Pursuant to the NOL Rights Plan, the Company’s board of directors (the “Board”) declared a dividend of one preferred share purchase right (each, a “Right”) for each outstanding share of Common Stock. The dividend was distributed to shareholders of record as of the close of business on February 25, 2019.

Lumen’s shareholders initially ratified the NOL Rights Plan on May 22, 2019, and subsequently ratified amendments to or restatements of such plan on May 19, 2021 and May 15, 2024.

The following is a summary description of the Rights and the other material terms and conditions of the NOL Rights Plan. This summary is intended to provide a general description only, does not purport to be complete and is qualified in its entirety by reference to, and should be read in conjunction with, the complete text of the NOL Rights Plan. All capitalized terms used herein but not defined herein shall have the meanings ascribed to such terms in the NOL Rights Plan.

Applicability of NOL Rights Plan

Under the NOL Rights Plan, since February 25, 2019, each share of our Common Stock has carried with it one Right until the Distribution Date (as defined below) or the earlier expiration of the Rights, as described below. Shareholders who owned 5.0% or more of the outstanding Common Stock as of the close of business on February 13, 2019, will not trigger the Rights so long as they do not (i) acquire additional shares of Common Stock representing one-half of one percent (0.5%) or more of the shares of Common Stock outstanding at the time of such acquisition or (ii) fall under 4.9% ownership of Common Stock and then re-acquire shares that in the aggregate equal 4.9% or more of the Common Stock. A person will not trigger the Rights solely as a result of any transaction that the Board determines, in its sole discretion, is an exempt transaction for purposes of triggering the Rights. To the Company’s knowledge, only one company held 5.0% or more of the Company’s outstanding shares of Common Stock on February 13, 2019, for purposes of Section 382 of the Code, and it has subsequently sold those shares.

The Board may, in its sole discretion prior to the Distribution Date, exempt any person or group for purposes of the NOL Rights Plan if it determines the acquisition by such person or group will not jeopardize tax benefits or is otherwise in the Company’s best interests. Any person that acquires shares of Common Stock in violation of these limitations is known as an “Acquiring Person.” Notwithstanding the foregoing, a Person shall not be an “Acquiring Person” if the Board determines at any time that a Person who would otherwise be an “Acquiring Person” has become such without intending to become an “Acquiring Person,” and such Person divests as promptly as practicable (or within such period of time as the Board determines is reasonable) a sufficient number of shares of Common Stock of the Company so that such Person would no longer be an “Acquiring Person,” as defined pursuant to the NOL Rights Plan.


#103495603v2    4


The Rights

From the record date of February 25, 2019 until the Distribution Date or earlier expiration of the Rights, the Rights will trade with, and be inseparable from, the Common Stock. New Rights will also accompany any new shares of Common Stock that are issued after February 13, 2019, until the Distribution Date or earlier expiration of the Rights.

Exercise Price

Each Right will allow its holder to purchase from the Company one ten-thousandth of a share of Series CC Junior Participating Preferred Stock (“Preferred Share”) for $9, subject to adjustment (the “Exercise Price”), once the Rights become exercisable. This fraction of a Preferred Share will give the shareholder approximately the same dividend, voting and liquidation rights as would one share of Common Stock. Prior to exercise, each Right does not give its holder any dividend, voting or liquidation rights.

Exercisability

The Rights will not be exercisable until 10 business days (as may be extended in the discretion of the Board) after the public announcement that a person or group has become an Acquiring Person unless the NOL rights Plan is theretofore terminated or the Rights are theretofore redeemed (as described below).

We refer to the date when the Rights become exercisable as the “Distribution Date.” Until that date or earlier expiration of the Rights, the Common Stock certificates will also evidence the Rights, and any transfer of shares of Common Stock will constitute a transfer of Rights. After that date, the Rights will separate from the Common Stock and be evidenced by book-entry credits or by Rights certificates that we will mail to all eligible holders of Common Stock. Any Rights held by an Acquiring Person, or any Affiliates or Associates of the Acquiring Person, are void and may not be exercised.

Consequences of a Person or Group Becoming an Acquiring Person

If a person or group becomes an Acquiring Person, all holders of Rights except the Acquiring Person, or any Affiliates or Associates of the Acquiring Person, may, upon payment of the Exercise Price, purchase shares of our Common Stock with a market value of twice the Exercise Price, based on the “current per share market price” of the Common Stock (as defined in the NOL Rights Plan) on the date of the acquisition that resulted in such person or group becoming an Acquiring Person.

Exchange

After a person or group becomes an Acquiring Person, the Board in its sole discretion may extinguish the Rights by exchanging one share of Common Stock or an equivalent security for each Right, other than Rights held by the Acquiring Person or any Affiliates or Associates of the Acquiring Person.

Preferred Share Provisions

Each one ten-thousandth of a Preferred Share, if issued:

#103495603v2    5



would not be redeemable;

would entitle holders to dividends equal to the dividends, if any, paid on one share of Common Stock;

would entitle holders upon liquidation either to receive $1.00 per share or an amount equal to the payment made on one share of Common Stock, whichever is greater;

would vote together with the Common Stock as one class on all matters submitted to a vote of shareholders of the Company and will have the same voting power as one share of Common Stock, except as otherwise provided by law; and

would entitle holders to a per share payment equal to the payment made on one share of Common Stock, if shares of our Common Stock are exchanged via merger, consolidation, or a similar transaction.

The value of each one ten-thousandth interest in a Preferred Share, upon issuance, is expected to approximate the value of one share of Common Stock.

Expiration

The Rights will expire on the earliest of (i) December 1, 2026, (ii) the time at which the Rights are redeemed, (iii) the time at which the Rights are exchanged, or (iv) the time at which the Board makes certain specified determinations that the NOLs are no longer necessary or in the best interests of the Company and its shareholders.

Redemption

The Board may redeem the Rights for $0.0001 per Right at any time before the Distribution Date. If the Board redeems any Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only right of the holders of Rights will be to receive the redemption price of $0.0001 per Right (the “Redemption Price”), subject to adjustment as noted below.

Adjustment Provisions

Upon the terms and conditions specified in the NOL Rights Plan, one or more of the Exercise Price, the number of Preferred Shares issuable per Right, the number of outstanding Rights and the Redemption Price are subject to adjustment in connection with a stock dividend, a subdivision, a combination or consolidation of Common Shares or Preferred Shares (by reclassification or otherwise) or any similar transaction in order to preserve equivalent rights of the holders of Rights.

Amendments

The terms of the NOL Rights Plan may be amended by the Board without the consent of the holders of the Rights, including to effect additional extensions of the expiration date of the Rights in the future. After any Distribution Date, the Board may not amend the agreement in a way that adversely affects holders of the Rights (other than an Acquiring Person, or an Affiliate or Associate of an Acquiring Person).

EACH PARTY HERETO (x) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.
(f)The Borrower hereby irrevocably and unconditionally waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 7 any special, exemplary, punitive or consequential damages.
SECTION 8.Headings. Section and Subsection headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose or be given any substantive effect.

Background and Summary of Significant Accounting Policies
Note 1 — Background and Summary of Significant Accounting Policies

General

We are a leading digital networking services company, empowering enterprise businesses to fuel growth in a multi-cloud, AI-first marketplace by connecting people, data, and applications quickly, securely, and effortlessly. We are unleashing the world's digital potential by providing a broad array of integrated products and services to our domestic and global Business customers and our domestic Mass Markets customers. We operate one of the world’s most interconnected communications networks. Our platform empowers our customers to swiftly adjust digital programs to meet immediate demands, create efficiencies, accelerate market access, and reduce costs, which allows our customers to rapidly evolve their IT programs to address dynamic changes. Our specific products and services are detailed in Note 4 — Revenue Recognition.

Basis of Presentation

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated.

To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows:

income attributable to noncontrolling interests in other income (expense), net;

equity attributable to noncontrolling interests in common stock; and

cash flows attributable to noncontrolling interests in other, net financing activities.

As of December 31, 2025, we no longer have any noncontrolling interests. We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting for 2024 and 2023. See Note 16 — Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses, or net loss for any period.

Operating Expenses

Our current definitions of operating expenses are as follows:

Cost of services and products (exclusive of depreciation and amortization): Expenses incurred in providing products and services to our customers. These expenses include:

employee-related expenses directly attributable to operating and maintaining our network (e.g., salaries, wages, benefits, and professional fees);

network and facilities expenses (e.g., third-party telecommunications expenses we incur for using other carriers' networks to provide services to our customers);

rents and utilities expenses;

equipment sales expenses (e.g., modem expenses); and

other expenses directly related to our operations.
Selling, general and administrative expenses: Corporate overhead and other operating expenses. These expenses include:

employee-related expenses directly attributable to selling products or services and employee-related expenses for administrative functions (e.g., salaries, wages, internal commissions, benefits and professional fees);

marketing and advertising;

property and other operating taxes and fees;

external commissions;

legal expenses associated with general matters;

bad debt expense; and

other selling, general, and administrative expenses.

These expense classifications may not be comparable to those of other companies.

Summary of Significant Accounting Policies

Use of Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and require management to make estimates and assumptions that affect reported amounts of assets, liabilities, equity, revenue, expenses, and cash flows and related disclosures. These estimates are based on information available at the time, including historical and forward-looking factors, that we believe are reasonable; however, these estimates may differ materially from actual results.

We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 15 — Income Taxes and Note 17 — Commitments, Contingencies and Other Items for additional information.

For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third-party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.

For matters related to income taxes, if we determine the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. We do not recognize any portion of an uncertain tax position if the position has less than a 50% likelihood of being sustained. We recognize interest on the amount of unrecognized benefit from uncertain tax positions.

Assets Held for Sale

Assets and related liabilities are classified as held for sale when:

management commits to a plan to sell the assets;

the assets are available for immediate sale;

an active program to locate a buyer is initiated; and

the sale is probable within one year.
Assets and related liabilities held for sale are presented separately at the lower of (i) carrying amount or (ii) fair value less costs to sell. If the carrying amount exceeds fair value less cost to sell, a loss is recognized. Depreciation and amortization cease once assets are classified as held for sale. Assets classified as held for sale are remeasured each reporting period to ensure they are stated at the lower of (i) carrying amount or (ii) fair value less costs to sell.

Unless otherwise specified, the amounts and information presented in the notes do not include assets and liabilities that were classified as held for sale. See Note 2 — Divestitures for details on our recently completed divestitures.

Revenue Recognition

We recognize revenue primarily from contracts with customers for communications and related services in accordance with Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" (“ASC 606”). Revenue is measured based on the consideration we expect to receive and is recognized when control of goods or services transfers to the customer. We also earn revenue from leasing arrangements (e.g., fiber capacity and conduit leases and colocation agreements) and governmental subsidies, which are outside the scope of ASC 606.

Under ASC 606, revenue is recognized using the following five-step model:

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when, or as, we satisfy a performance obligation.

Service and Equipment Revenue

We provide a broad range of communications services to business and residential customers — including global, enterprise, wholesale, government, and small and medium business customers. Certain contracts include equipment sales, which are not significant to our operations. We recognize revenue for services when we provide the applicable service or when control of a product is transferred.

For arrangements using third-party vendors, we assess whether we act as a principal or agent to determine whether revenue is reported on a gross or net basis.

Performance Obligations

Customer contracts are evaluated to determine whether the performance obligations are separable. If the performance obligations are deemed separable and separate earnings processes exist, the transaction price is allocated to each performance obligation based on its relative standalone selling price. The revenue associated with each performance obligation is then recognized as when, or as, the performance obligation is satisfied.

Deferred Revenue and Fees

Payments received in advance — such as design, planning, engineering, activation, or installation fees — are deferred unless they represent separate performance obligations. When these payments are not separate obligations, we recognize them over the contract term or estimated useful life, typically one to five years, based on historical experience. Termination fees or other charges negotiated with new contracts are also deferred and recognized over the new contract term.
Billing Practices

For access services, we generally bill fixed monthly charges one month in advance to customers and recognize revenue as service is provided over the contract term in alignment with the customer's receipt of service. For usage and other ancillary services, we generally bill in arrears and recognize revenue as usage or delivery occurs. In most cases, the amount invoiced for our service offerings constitutes the price that would be billed on a standalone basis.

Customer payments are made based on billing schedules included in our customer contracts, which is typically on a monthly basis.

Contract Costs

We defer (or capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 47 months for Mass Markets customers and 34 months for Business customers. These deferred costs are periodically monitored to reflect any significant change in assumptions.

Contract Modifications

In certain cases, customers may be permitted to modify their contracts. We evaluate the change in scope or price to identify whether the modification should be treated as a separate contract, as a termination of the existing contract and creation of a new contract, or as a change to the existing contract.

Indefeasible Rights of Use and Leases

We periodically sell transmission capacity on our network through indefeasible rights of use (“IRU”s), which grant the exclusive right to use a specified amount of capacity or fiber for a typical term of 20 years. Cash consideration received on transfers of transmission capacity is recognized as ASC 606 revenue, adjusted for time value of money and recognized ratably over the term. Cash consideration received on transfers of dark fiber is treated as non-ASC 606 lease revenue, which we also recognized ratably over the lease term. We treat contemporaneous exchanges of transmission capacity assets as non-revenue generating activities and therefore do not recognize revenue for these exchanges.

Service Level Commitments

We have service level commitments pursuant to contracts with certain of our customers. To the extent that we determine that such service levels were not achieved or may not have been achieved, we estimate the amount of credits to be issued and record a corresponding reduction to revenue in the period that the service level commitment was not met or may not be met.

See Note 4 — Revenue Recognition for additional information.

Advertising Costs

Costs related to advertising are expensed as incurred and recorded as selling, general and administrative expenses in our consolidated statements of operations. Our advertising expenses were:

Years Ended December 31,
202520242023
Advertising costs
$84 94 87 

Legal Costs

In the normal course of our business, we incur costs to hire and retain external legal counsel to advise us on finance, regulatory, litigation, and other matters. Subject to certain exceptions, we expense these costs as the related services are received.
Income Taxes

We file a consolidated federal income tax return with our eligible subsidiaries. The provision for income taxes reflects taxes currently payable, tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to tax attributes carryforwards, including NOL carryforwards and tax credit carryforwards, and differences between the financial statement carrying value of assets and liabilities and the tax basis of those assets and liabilities. Deferred taxes are computed using enacted tax rates expected to apply in the year in which the differences are expected to affect taxable income. The effect on deferred income tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date.

We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain or adjust each valuation allowance on our deferred tax assets. See Note 15 — Income Taxes for additional information.

Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments that are readily convertible into cash and are not subject to significant risk from fluctuations in interest rates. As a result, the value at which cash and cash equivalents are reported in our consolidated financial statements approximates their fair value. In evaluating investments for classification as cash equivalents, we require that individual securities have original maturities of ninety days or less and that individual investment funds have dollar-weighted average maturities of ninety days or less. To preserve capital and maintain liquidity, we invest with financial institutions we deem to be of sound financial condition and in high quality and relatively risk-free investment products. Our cash investment policy limits the concentration of investments with specific financial institutions or among certain products and includes criteria related to credit worthiness of any particular financial institution.

Book overdrafts occur when we have issued checks but they have not yet been presented to our controlled disbursement bank accounts for payment. Disbursement bank accounts allow us to delay funding of issued checks until the checks are presented for payment. Until the issued checks are presented for payment, the book overdrafts are included in accounts payable on our consolidated balance sheets. This activity is included in the operating activities section in our consolidated statements of cash flows.

Restricted Cash

Restricted cash consists primarily of cash and investments that collateralize our outstanding letters of credit and certain performance and operating obligations. Restricted cash is recorded as current or non-current assets in the consolidated balance sheets depending on the duration of the restriction and the purpose for which the restriction exists.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recognized based upon the amount due from customers for the services provided or at cost for purchased and other receivables, less an allowance for credit losses. We use a loss rate method to estimate our allowance for credit losses. For more information on our methodology for estimating our allowance for credit losses, see Note 6 — Credit Losses on Financial Instruments.

We generally consider our accounts past due if they are outstanding over 30 days. Our past due accounts are written off against our allowance for credit losses and any recoveries are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable net of the allowance for credit losses approximates fair value. Accounts receivable balances acquired in a business combination are recorded at fair value for all balances receivable at the acquisition date and at the invoiced amount for those amounts invoiced after the acquisition date.
Property, Plant and Equipment

Purchased and constructed property, plant, and equipment are recorded at cost and assets acquired through business combinations are recorded at their estimated fair value as of the acquisition date. In both instances we include the estimated value of any associated legally or contractually required retirement obligations.

Expenditures for maintenance and repairs are expensed as incurred. Supplies used internally are carried at average cost, except for significant individual items which are carried at actual cost.

Depreciation Methods

Prior to January 1, 2024: Most assets were depreciated using the straight-line group method. Under this approach, assets with similar characteristics and useful lives were pooled together and depreciated over the group’s average remaining useful life. When assets were sold or retired in the normal course of business, their cost was removed from both the asset and accumulated depreciation accounts, with no gain or loss recognized.

Effective January 1, 2024: We re-established all of our assets individually, including accumulated depreciation, and transitioned to depreciating all assets individually using the straight-line method over each asset’s estimated useful life. When assets are sold in the normal course of business, a gain or loss is recognized in our consolidated statements of operations.

Leasehold Improvements and Capital Projects

Leasehold improvements are amortized over the shorter of the assets’ useful lives or the expected lease term. During the construction phase of network and other internal-use capital projects, we capitalize related employee and interest costs.

Useful Lives

We perform annual internal reviews to evaluate the reasonableness of the depreciable lives for our property, plant and equipment. Our reviews utilize models that take into account actual usage, physical wear and tear, replacement history, and assumptions about technology evolution. Our remaining useful life assessments evaluate the possible loss in service value of assets that may precede the physical retirement. Assets shared among many customers may lose service value as those customers reduce their use of the asset. However, the asset is not retired until all customers no longer utilize the asset and we determine there is no alternative use for the asset.

Impairment Testing

We review long-lived tangible assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. For assessment purposes, long-lived assets are grouped with other assets and liabilities at the lowest identifiable level for which we generate cash flows independently of other groups of assets and liabilities. An impairment loss is recognized only if the carrying amount of the asset group is not recoverable and exceeds its estimated fair value. Recoverability of the asset group to be held and used is assessed by comparing the carrying amount of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. If the asset group's carrying value is not recoverable, we recognize an impairment charge for the amount by which the carrying amount of the asset group exceeds its estimated fair value.
Asset Retirement Obligations

We recognize asset retirement obligations (“ARO”s) for the legally or contractually required removal of certain property, plant, and equipment from leased properties, as well as for the disposal of hazardous materials in owned facilities. When an ARO is identified — typically at the time an asset is acquired — we record the fair value of the obligation as a liability and capitalize a corresponding amount as part of the asset’s cost. Our fair value estimates were determined using the discounted cash flow method. In subsequent periods, we increase the ARO liability for the passage of time (accretion expense) and adjust the liability and related asset for changes in the timing or amount of expected future cash flows. The capitalized amount is then amortized over the asset’s estimated remaining useful life. If a removal obligation is not legally binding, we expense the related removal costs as incurred, rather than capitalizing them.

Goodwill and Intangible Assets

Intangible assets acquired in business combinations — including goodwill, customer relationships, capitalized software, trademarks, and trade names — are recorded at estimated fair value at the acquisition date. Other intangible assets not arising from business combinations are initially recorded at cost.

We are required to reassign goodwill to reporting units whenever reorganizations of our internal reporting structure change the composition of our reporting units. Goodwill is reassigned to the reporting units using a relative fair value approach. As our remaining goodwill was fully impaired or reclassified as held for sale as of December 31, 2025, no further reassignment is required as the goodwill balance has been reduced to zero. When the fair value of a reporting unit is available, we allocate goodwill based on the relative fair value of the reporting units. When fair value is not available, we utilize an alternative allocation methodology that we believe represents a reasonable approximation of the fair value of the operations being reorganized.

Amortization

Intangible assets without legal, regulatory, contractual, or other limiting factors are classified as indefinite-lived and are not amortized. For finite-lived intangible assets, we amortize using the straight-line method over the following estimated lives:

Customer relationships: 7 - 14 years, depending on customer type

Capitalized software: 3 - 7 years

Other intangible assets: 9 - 20 years

Internal Use Software

Internally used software, whether purchased or developed by us, is capitalized and amortized using the straight-line method over its estimated useful life. We capitalized costs of employees devoted to software development and external direct costs for materials and services. Costs are expensed until the project reaches the development stage. Subsequent additions, modifications, or upgrades are capitalized only if they add new functionality. Software maintenance, data conversion, and training costs are expensed as incurred. We review the remaining economic lives of our capitalized software annually. Capitalized software is included in other intangible assets, net, in our consolidated balance sheets.
Impairment Testing

Finite-lived intangible assets are evaluated for impairment when triggering events or changes in circumstances occur. If fair value is less than the carrying amount, we record an impairment charge for the difference.

We test goodwill for impairment annually as of October 31, or more frequently if events suggest a reporting unit’s fair value may fall below its carrying value. If the carrying value of a reporting unit exceeds its fair value of equity, we write-down goodwill. Because reporting units are not separate legal entities with full financial statements, we determine equity carrying value and future cash flows during each impairment assessment we perform on a reporting unit. This involves allocating assets, liabilities, and cash flows to reporting units using reasonable, consistent methodologies. This process requires significant estimates, judgments, and assumptions.

For more information, see Note 3 — Goodwill and Intangible Assets.

Pension and Post-Retirement Benefits

We recognize the funded status of our defined benefit and post-retirement plans as an asset or a liability on our consolidated balance sheets. Each year's actuarial gains or losses are a component of our other comprehensive income (loss), which is then included in our accumulated other comprehensive loss on our consolidated balance sheets. Pension and post-retirement benefit expenses are recognized over the period in which the employee renders service and becomes eligible to receive benefits. We make significant assumptions (including the discount rate, expected rate of return on plan assets, mortality and health care trend rates) in computing the pension and post-retirement benefits expense and obligations. See Note 11 — Employee Benefits for additional information.

Foreign Currency

Local currencies of our foreign subsidiaries are the functional currencies for financial reporting purposes except for certain foreign subsidiaries. For operations with functional currencies other than the U.S. dollar, assets and liabilities are translated at period-end exchange rates, while revenue, expenses and cash flows use average monthly rates. Foreign currency translation gains and losses are recorded in accumulated other comprehensive loss in stockholders' (deficit) equity and in our consolidated statements of comprehensive (loss) income.

Before the November 1, 2023 sale of our EMEA business, many of our non-United States subsidiaries used the British pound or Euro as their functional currency, both of which fluctuated significantly against the U.S. dollar during the periods covered in this report when we operated the divested business. Prior to the divestiture, most investments in foreign subsidiaries were considered long-term. We continue to have immaterial operations transacted in foreign currencies. Foreign currency transaction gains and losses, including those not deemed long-term, are reported in other income (expense), net on our consolidated statements of operations.

For additional details on the sale of our EMEA business, see Note 2 — Divestitures.

Common Stock

On December 18, 2024, we amended our articles of incorporation to eliminate the par value of our common stock (which was, prior to such amendment, $1.00 per share) as approved by our shareholders at our 2024 annual shareholders meeting. We recognized the change by reclassifying the balance in Additional paid-in capital to Common stock on our consolidated balance sheet as of December 18, 2024. All changes in capitalization previously recognized as Additional paid-in capital will hereinafter be recognized in Common stock. This change had no other impact on our consolidated financial statements.

As of December 31, 2025, we had 24 million shares authorized for future issuance under our equity incentive plans.
Preferred Stock

Holders of outstanding Lumen Technologies preferred stock are entitled to receive cumulative dividends, receive preferential distributions equal to $25 per share plus unpaid dividends upon Lumen's liquidation and vote as a single class with the holders of common stock.

Section 382 Rights Agreement

We maintain a Section 382 Rights Agreement to protect our U.S. federal net operating loss carryforwards ("NOLs") from certain Internal Revenue Code Section 382 limitations. Under the agreement, one preferred stock purchase right was distributed for each share of our outstanding common stock as of the close of business on February 25, 2019, and those rights currently trade in tandem with the common stock until they expire or detach under the agreement. This agreement was designed to deter trading that would result in a change of control (as defined in Internal Revenue Code Section 382), and therefore protect our ability to use our historical federal NOLs in the future. The agreement is scheduled to lapse in late 2026.

Dividends

The declaration and payment of dividends is at the discretion of our Board of Directors. We do not currently pay a dividend on our common stock.

Recently Adopted Accounting Pronouncements

Segments

On January 1, 2024, we adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The ASU does not change how a public entity identifies its operating segments, aggregates them or applies quantitative thresholds to determine reportable segments. Refer to Note 16 — Segment Information for more information.

Investments

On January 1, 2024, we adopted ASU 2023-02, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." This ASU allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The adoption of this ASU did not have any impact on our consolidated financial statements.

On January 1, 2024, we adopted ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." This ASU clarifies that a contractual restriction on the sales of an investment in an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring its fair value. The adoption of this ASU did not have any impact on our consolidated financial statements.

Leases

In November 2025, the FASB issued ASU 2025-08, "Financial Instruments — Credit Losses (Topic 326): Purchased Loans." This ASU requires that loans acquired without credit deterioration and deemed “seasoned” will be considered purchased seasoned loans and accounted for using the gross-up approach at acquisition (i.e., record the loan at its purchase price and separately record an allowance for expected credit losses). Seasoned loans include all loans acquired in a business combination, that do not have “more-than-insignificant” deterioration of credit quality since origination, as well as loans purchased at least 90 days after origination, where the purchaser was not involved in the origination of the loans. The amendments in ASU 2025-08 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early adoption permitted. This ASU should be applied prospectively to loans that are acquired on or after the initial application date. The Company intends to early adopt ASU 2025-08 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

This ASU is permitted to be applied either prospectively to new contracts entered into on or after the date of adoption or on a modified retrospective basis through a cumulative-effect adjustment to the opening balance of retained earnings. The Company intends to early adopt ASU 2025-07 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, "Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software" which amends the guidance in ASC 350-40, "Intangibles — Goodwill and Other — Internal-Use Software." This ASU modernizes the recognition and disclosure framework for internal-use software costs, removing the previous “development stage” model and introducing a more judgment-based approach. The amendments in ASU 2025-06 are effective for fiscal years beginning after December 15, 2027, and for interim periods within those annual reporting periods, with early adoption permitted. This ASU is permitted to be applied prospectively, retrospectively or through a modified transition approach. The Company intends to early adopt ASU 2025-06 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05 "Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." This ASU provides entities with a practical expedient to simplify the estimation of expected credit losses on current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606 by allowing the assumption that current conditions as of the balance sheet date will not change during the remaining life of the asset. The amendments in ASU 2025-05 are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early prospective adoption permitted. The Company is currently evaluating ASU 2025-05 to determine the impact it may have on our consolidated financial statements.
In May 2025, the FASB issued ASU 2025-04 "Compensation - Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”)." This ASU clarifies the guidance on the accounting for share-based payment awards that are granted by an entity as consideration payable to its customer, with the intent to reduce diversity in practice and improve existing guidance by revising the definition of a “performance condition” and eliminating a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. It also clarifies the guidance in Topic 606 on the variable consideration constraint does not apply to share-based consideration payable to a customer “regardless of whether an award’s grant date has occurred”. ASU 2025-04 will be effective for the annual periods beginning after December 15, 2026 with early adoption permitted. The Company intends to early adopt ASU 2025-04 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In May 2025, the FASB issued ASU 2025-03 "Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity." This ASU revises current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity that meets the definition of a business. The amendments require an entity to consider the same factors that are currently required for determining which entity is the accounting acquirer in other acquisition transactions. The amendments in ASU 2025-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early prospective adoption permitted. The Company intends to early adopt ASU 2025-03 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, "Debt — Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments."

The amendments in ASU 2024-04 are effective for the annual period of fiscal 2026, and early adoption is permitted. This ASU is permitted to be applied on either a prospective or retrospective basis. As of December 31, 2025, we do not hold convertible debt instruments and do not expect this ASU will have any impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses." This ASU requires additional footnote disclosure of the details of certain income statement expense line items as well as additional disclosure about selling expenses.

Discontinued Operations and Disposal Groups [Abstract]  
Divestitures
Note 2 — Divestitures

EMEA Business

On November 1, 2023, affiliates of Level 3 Parent, LLC, sold Lumen's operations in Europe, the Middle East and Africa ("EMEA") to Colt Technology Services Group Limited, a portfolio company of Fidelity Investments, for pre-tax cash proceeds of $1.7 billion after certain closing adjustments and transaction costs. This consideration is further subject to other post-closing adjustments and indemnities set forth in the purchase agreement, as amended and supplemented to date. In connection with the sale, we entered into a transition services agreement under which we provide the purchaser various support services. In addition, Lumen and the purchaser entered into commercial agreements whereby they provide each other various network and other commercial services.

The classification of the EMEA business as held for sale was considered an event or change in circumstance which requires an assessment of the goodwill of the disposal group for impairment each reporting period until disposal. We performed a pre-classification and post-classification goodwill impairment test of the disposal group as described further in Note 3 — Goodwill and Intangible Assets. As a result of our impairment tests, we determined the EMEA business disposal group was impaired, resulting in a non-cash, non-tax-deductible goodwill impairment charge of $43 million in the fourth quarter of 2022. We evaluated the recoverability of the carrying value of the assets and liabilities held for sale relative to the agreed upon sales price, adjusted for costs to sell, and recorded an estimated loss on disposal of $660 million during the year ended December 31, 2022 in the consolidated statement of operations and a valuation allowance included in assets held for sale on the consolidated balance sheet as of December 31, 2022. For the year ended December 31, 2023, we recorded a $102 million net loss on disposal associated with the sale of our EMEA business. This loss is reflected as operating expense within the consolidated statements of operations.

The EMEA business was included in our continuing operations and classified as assets and liabilities held for sale on our consolidated balance sheets through the closing of the transaction on November 1, 2023. As a result of closing the transaction, we derecognized net assets of $2.1 billion, primarily made up of (i) property, plant and equipment, net of accumulated depreciation, of $2.0 billion and (ii) customer relationships and other intangible assets, net of accumulated amortization of $107 million. In addition, we reclassified $382 million of realized loss on foreign currency translation, net of tax, with an offset to the valuation allowance and loss on sale of the EMEA business.

Mass Markets Fiber-to-the-Home Business

On May 21, 2025, we entered into a definitive agreement to sell our Mass Markets Fiber-to-the-Home business in 11 states (the "Territory") to AT&T for $5.75 billion in cash, subject to working capital and other negotiated purchase price adjustments.

The actual amount of our net after-tax proceeds from this divestiture could vary substantially from the amounts we currently estimate, including if there are changes in other assumptions that impact our estimates.

As of December 31, 2025 in the accompanying consolidated balance sheet, the assets and liabilities of the disposal group are classified as held for sale and measured at the lower of (i) the carrying value when we classified the disposal group as held for sale or (ii) the fair value of the disposal group, less costs to sell. Effective with the designation of the disposal group as held for sale on May 21, 2025, we suspended recording depreciation of property, plant and equipment while these assets are classified as held for sale. We estimate that we would have recorded an additional $104 million of depreciation for the year ended December 31, 2025 if the disposal group did not meet the held for sale criteria.

Under the terms of the purchase agreement related to the sale of the Mass Market Fiber-to-the-Home business in the Territory, Lumen agreed to grant the purchaser an indefeasible right to use (“IRU”) certain Lumen retained fiber assets following the closing of the transaction in order to service the transferred customer contracts. The value of these retained Lumen assets subject to the IRU is excluded from assets held for sale in the table below.
The principal components of the held for sale assets and liabilities of the disposal group as of December 31, 2025 are as follows:

Subsequent Event

On February 2, 2026, we and certain of our affiliates completed the sale of our Mass Markets Fiber-to-the-Home business in 11 states to AT&T in exchange for pre-tax cash proceeds of approximately $5.75 billion, subject to working capital and other negotiated post-closing adjustments. In connection with the sale, Lumen has entered into a transition services agreement under which it will provide to the purchaser various support services and certain long-term agreements under which Lumen and the purchaser will provide to each other various network and other commercial services.

Treatment of Consolidated Operating Results of Divested Businesses
We do not believe the divestiture of the EMEA business or the recently completed divestiture of the Mass Markets Fiber-to-the-Home business represent a strategic shift for Lumen, and therefore do not qualify as discontinued operations. As a result, we continued to report our operating results for the EMEA business and the Mass Markets Fiber-to-the-Home business in our consolidated operating results through their respective disposal dates of November 1, 2023 and February 2, 2026.

(1)We recorded cumulative non-cash, non-tax-deductible goodwill impairment charges of $628 million during the year ended December 31, 2025.
(2)As of December 31, 2025, this amount excluded goodwill classified as held for sale of approximately $1.3 billion. See Note 2 — Divestitures.
(3)Certain capitalized software with a gross carrying value of $161 million and $352 million and trade names with a gross carrying value of $211 million and $153 million became fully amortized during 2024 and 2023, respectively, and were retired during the first quarter of 2025 and 2024, respectively.

As of December 31, 2025 and December 31, 2024, the gross carrying amount of goodwill and intangible assets was $13.4 billion and $15.4 billion, respectively, excluding the amounts classified as held for sale.

We are required to assess our goodwill and other indefinite-lived intangible assets for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. As of December 31, 2025, we had no indefinite-lived intangible assets and our remaining goodwill was classified as held for sale. As such, we did not perform any annual impairment assessment for the year ended December 31, 2025 and the only impairment testing performed on our goodwill for the year-ended December 31, 2025 was performed on April 30, 2025 due to a triggering event as described below. Our annual impairment assessment date for indefinite-lived intangible assets other than goodwill was historically December 31. We completed our qualitative assessment of our indefinite-lived intangible assets other than goodwill as of December 31, 2024 and 2023 and concluded it is more likely than not that our indefinite-lived intangible assets were not impaired; thus, no impairment charge for these assets was recorded in 2024 or 2023.

Our goodwill was historically derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired. We are required to write down the value of goodwill only when our assessment determines the carrying value of equity of any of our reporting units exceeds its fair value. Our annual impairment assessment date for goodwill was October 31, at which date we assessed our reporting units.

We report our results within two segments: Business and Mass Markets. See Note 16 — Segment Information for more information on these segments and the underlying sales channels. As of April 30, 2025, we had three reporting units for goodwill impairment testing, which were:

Mass Markets;

North America Business ("NA Business"); and

Asia Pacific ("APAC") region.

Prior to the divestiture of the EMEA business in November 2023, the EMEA region was also a reporting unit and was tested for impairment.
Our reporting units are not discrete legal entities with discrete full financial statements. Our assets and liabilities are deployed in and relate to the operations of multiple reporting units. When we assess goodwill for impairment, we compare the estimated fair value of each reporting unit's equity to the carrying value of equity that we assign to the reporting unit. If the estimated fair value of the reporting unit is greater than the carrying value, we conclude that no impairment exists. If the estimated fair value of the reporting unit is less than the carrying value, we record a non-cash impairment charge equal to the excess amount. Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours.

Goodwill Impairment Analysis

2025 Goodwill Impairment Analysis

During the second quarter of 2025, we determined that the classification of the Mass Markets Fiber-to-the-Home business in the Territory as held for sale as described in Note 2 — Divestitures was considered an event or change in circumstance which required an assessment of our goodwill for impairment as of April 30, 2025. We performed a pre-classification goodwill impairment assessment, as of April 30, 2025, using the market approach to test for impairment prior to the classification of these assets as held for sale and to determine the fair value of our Mass Markets reporting unit for the assignment of goodwill held for sale. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry which supported a range of fair values derived from annualized revenue and earnings before interest, tax, depreciation and amortization ("EBITDA") multiples between 1.8x and 3.1x and 5.8x and 8.0x, respectively. We reconciled the estimated fair values of the reporting units to our market capitalization as of April 30, 2025 and concluded that the indicated control premium of approximately 42% was reasonable based on recent market transactions. We concluded no impairment existed at any of our reporting units as of our April 30, 2025 assessment date.

We also performed a post-classification goodwill impairment test using the market approach to evaluate whether the fair value of our reporting units that will remain following the divestiture exceeds the carrying value of the equity of such reporting units after classification of assets held for sale and concluded the indicated control premium of approximately 4% was reasonable based on recent market transactions. As a result of this analysis, we determined that the Mass Markets reporting unit was fully impaired, resulting in us recognizing a non-cash, non-tax-deductible goodwill impairment charge of $628 million during the quarter ended June 30, 2025.

The market approach we used in the quarter ended June 30, 2025 incorporated estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain strategic initiatives. In developing the market multiples applicable for each reporting unit, we considered observed trends of our industry participants. Our assessment included many factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairment.

Subsequent to this impairment analysis and as of December 31, 2025, our only remaining goodwill was classified as held for sale.

2024 Goodwill Impairment Analysis

As of October 31, 2024, we performed our annual impairment analysis of the goodwill in our Mass Markets reporting unit by using a qualitative assessment to determine whether it was more likely than not that the fair value of the reporting unit was less than its carrying value. Factors considered in the qualitative assessment included, among other things, macroeconomic conditions, industry and market conditions, financial performance of the reporting unit and other relevant entity and reporting unit considerations. We concluded the estimated fair value of our reporting unit was greater than our carrying value of equity as of our testing date. Therefore, we concluded no impairment existed as of our annual assessment date in the fourth quarter of 2024.
2023 Goodwill Impairment Analyses

During 2023, we recorded non-cash and non-tax-deductible goodwill impairment charges totaling $10.7 billion related to certain reporting units. In the second quarter of 2023, we determined circumstances existed indicating it was more likely than not that the carrying value of our reporting units exceeded their fair value, resulting in an impairment charge of $8.8 billion. An additional $1.9 billion was recorded as part of our annual goodwill impairment analysis of our three reporting units performed on October 31, 2023

Given the continued erosion in our market capitalization, both quantitative impairment analyses were performed using the market approach, which relied on company comparisons and analyst reports within the telecommunications industry to develop fair value ranges based on annualized revenue and EBITDA multiples. For each of our assessments, we used revenue and EBITDA multiples below these comparable market multiples. Estimated fair values were reconciled to market capitalization, and any implied control premium was determined to be reasonable based on recent market transactions at that time. Significant judgment was required in developing assumptions, and alternative interpretations could have resulted in different conclusions regarding the size of our impairments.

The following table shows the rollforward of goodwill assigned to our reportable segments.

(2)     As of December 31, 2025, this amount excluded $32 million of contract liabilities associated with the disposal group classified as held for sale.

Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation, and maintenance charges that are deferred and recognized over the actual or expected contract term, which typically ranges from one to five years depending on the service. Contract liabilities are included within Deferred revenue on our consolidated balance sheets. During the years ended December 31, 2025 and December 31, 2024, we recognized $478 million and $443 million, respectively, of revenue that was included in contract liabilities of $733 million and $698 million as of January 1, 2025 and 2024, respectively, including contract liabilities that were classified as held for sale.

Performance Obligations

As of December 31, 2025, we expect to recognize approximately $6.0 billion of revenue in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied. As of December 31, 2025, the transaction price related to unsatisfied performance obligation that are expected to be recognized in 2026, 2027, and thereafter was $2.8 billion, $1.6 billion and $1.6 billion, respectively.

These amounts exclude:

the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed (for example, uncommitted usage or non-recurring charges associated with professional or technical services to be completed);

contracts that are classified as leasing arrangements or government assistance that are not subject to ASC 606; and

the value of unsatisfied performance obligations for contracts which relate to the disposal group classified as held for sale.

______________________________________________________________________
(1)    The ending balance for the year ended December 31, 2025 excluded $24 million and $21 million of acquisition costs and fulfillment costs, respectively, associated with the disposal group classified as held for sale.

Acquisition costs include commission fees paid to employees as a result of obtaining contracts. Fulfillment costs include third-party and internal costs associated with the provision, installation and activation of services to customers, including labor and materials consumed for these activities.

We amortize deferred acquisition and fulfillment costs based on the transfer of services on a straight-line basis over the average contract life of approximately 47 months for Mass Markets customers and 34 months for Business customers. We include amortized fulfillment costs in Cost of services and products and amortized acquisition costs in Selling, general and administrative in our consolidated statements of operations. We include the amount of these deferred costs that are anticipated to be amortized in the next 12 months in Other current assets, net and the deferred costs expected to be amortized beyond the next 12 months in Other assets, net on our consolidated balance sheets. We assess deferred acquisition and fulfillment costs for impairment on a quarterly basis.

Governmental Funding

Lumen participates in various U.S. federal and state programs under which government support payments are received to offset costs associated with providing services in targeted locations such as unserved or underserved high-cost or rural areas, or for certain types of customers, including non-profit organizations, educational institutions and local governmental bodies. In certain instances, support payments are conditioned on specified infrastructure buildouts by milestone deadlines or provision of services at specified locations and speed requirements. Commitments may be made annually, on a multi-year basis ranging from one to 10 years or be on-going subject to periodic change or termination. Consistent with customary practice and as referenced in ASC 832 Government Assistance, Lumen applies a grant model of accounting by which it accounts for these transactions as non-ASC 606 revenue over the periods in which the costs for which the funding is intended to compensate are incurred. This non-ASC 606 revenue is included in operating revenue in our consolidated statements of operations. Corresponding receivables are recorded when services have been provided to the customers and costs incurred, but the cash has not been received. These amounts are included in our accounts receivable, less allowance in our consolidated balance sheets. Certain programs are subject to audits of compliance with program commitments and, subject to the outcomes of those assessments, Lumen may be required to reimburse the government entity for cash previously received, or, in some cases, pay a penalty. Lumen evaluates each program and establishes a liability under the principles of ASC 450 if it is probable support payments will be recaptured or a penalty will be imposed.

For both the years ended December 31, 2025 and 2024, Lumen recorded non-customer revenue of $67 million and $83 million, respectively, under government assistance programs, of which 28% and 18%, respectively, was associated with state universal service fund support programs.
The federal government has introduced several programs expand broadband access, including the Rural Digital Opportunity Fund (“RDOF”) program, an FCC initiative that provides federal financial support to fund broadband deployment in rural America. We were awarded RDOF funding in several of the states in which we operate and received payments for a period starting in 2022. We received approximately $17 million in annual RDOF Phase I support payments for the year ended December 31, 2023. In the third quarter of 2024, we relinquished rights to develop certain RDOF census blocks in four states, which resulted in a reduction of the anticipated RDOF Phase I support payments to approximately $16 million for the year ending December 31, 2024. In the second quarter of 2025, we voluntarily relinquished the remainder of our RDOF awards. As a result, we will no longer receive funding through the RDOF program and recognized a reduction to revenue of $46 million in our consolidated statements of operations in the second quarter of 2025. We also incurred fees of $49 million in connection therewith, which are reflected in our operating expenses within our consolidated statements of operations. In January 2026, we paid the $95 million of revenue and fees summarized above, along with an additional $4 million relating to our 2024 relinquishment as repayment of funds previously received and remittance of the fees incurred.

Lumen participates in two state sponsored programs for broadband deployment in unserved and underserved areas for which the states have state universal service funds sourced from fees levied on telecommunications providers and passed on to consumers. During the years ending December 31, 2025 and 2024, Lumen participated in these types of programs in the states of Nebraska and New Mexico.

Leases [Abstract]  
Leases
Note 5 — Leases

We primarily lease various office facilities, colocation facilities, equipment and transmission capacity to or from third parties. Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheets; we recognize lease expense for these leases on a straight-line basis over the lease term.

We determine if an arrangement is a lease at inception and whether that lease meets the classification criteria of a finance or operating lease at the commencement date. Lease-related assets, or right-of-use assets, are recognized at the lease commencement date at amounts equal to the respective lease liabilities. Lease-related liabilities are recognized at the present value of the remaining contractual fixed lease payments, discounted using our incremental borrowing rates. As part of the present value calculation for the lease liabilities, we use an incremental borrowing rate as the rates implicit in the leases are not readily determinable. The incremental borrowing rates used for lease accounting are based on our unsecured rates, adjusted to approximate the rates at which we could borrow on a collateralized basis over a term similar to the recognized lease term. We apply the incremental borrowing rates to lease components using a portfolio approach based upon the length of the lease term and the reporting entity in which the lease resides. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.

Some of our lease arrangements contain lease components, non-lease components (including common-area maintenance costs) and executory costs (including real estate taxes and insurance costs). We generally account for each component separately based on the estimated standalone price of each component. For colocation leases, we account for the lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless we determine that we are reasonably certain of renewing the lease. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain to be exercised. Our lease agreements do not generally contain any material residual value guarantees or material restrictive covenants.

We lease various equipment, office facilities, retail outlets, switching facilities and other network sites or components from third parties. These leases, with few exceptions, provide for renewal options and rent escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The lease term for most leases includes the initial non-cancelable term plus any term under renewal options that we believe are reasonably assured.

Credit Losses on Financial Instruments
Note 6 — Credit Losses on Financial Instruments

To assess our expected credit losses on financial instruments, we aggregate financial assets with similar risk characteristics to monitor their credit quality or deterioration over the life of such assets. We periodically monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change. We separately evaluate financial assets that do not share risk characteristics with other financial assets. Our financial assets measured at amortized cost primarily consist of accounts receivable.
We use a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our review of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable.

If there is an unexpected deterioration of a customer's financial condition or an unexpected change in economic conditions, including macroeconomic events, we assess the need to adjust the allowance for credit losses. Any such resulting adjustments would affect earnings in the period that adjustments are made.

The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding our allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future, and we may use methodologies that differ from those used by other companies.

(1)Except for Lumen's Term Loan A and $1.375 billion of Level 3 Financing's 11.000% First Lien Notes due 2029, all of the debt listed in this table was issued in the first quarter of 2024 in exchange for previously-issued debt of Lumen or Level 3 Financing in connection with the TSA Transactions.
(2)Reflects approximately $66 million of term loan installment payments and paydowns made between the TSA Effective Date and December 31, 2024.

In evaluating the terms of the TSA Transactions, we determined that for certain of our creditors the new debt instruments were substantially different than pre-existing debt and therefore constituted a non-cash extinguishment of old debt for Lumen Technologies and Level 3 Financing of $744 million and $2.6 billion, respectively, and the establishment of new debt for which we recorded a $275 million gain on extinguishment in the first quarter of 2024. This new debt was recorded at fair value generating a reduction to debt of $492 million which was included in our aggregate Net (loss) gain on early retirement of debt of $348 million, recognized in Other income (expense), net in our consolidated statement of operations for the year ended December 31, 2024. The remaining creditors’ newly-issued debt was not substantially different under the terms of the TSA Transactions and was treated under modification accounting rules. In conjunction with the TSA Transactions, we paid $209 million in lender fees and $174 million in additional third-party costs. Of these amounts, we offset $157 million of lender fees against the gain on extinguishment and recorded $112 million in third-party costs to Selling, general and administrative expense in our consolidated statement of operations for the year ended December 31, 2024. In accordance with GAAP provisions for modification and extinguishment accounting, $52 million in lender fees and $62 million in third-party costs, respectively, were capitalized and will be amortized over the terms of the newly-issued indebtedness.
Repurchases of Debt Instruments

During 2024, we repurchased various debt instruments on the open market. These repurchases resulted in an aggregate net gain of $40 million which is included in our aggregate Net (loss) gain on early retirement of debt in Other income (expense), net in our consolidated statement of operations for the year ended December 31, 2024. The following table sets forth the aggregate principal amount of each series of notes and term loans repurchased during the year ended December 31, 2024:

Lumen Credit Agreements

Superpriority Revolving/Term A Credit Agreement

On the TSA Effective Date, Lumen, as borrower, the lenders party thereto and Bank of America, as administrative agent and collateral agent, entered into the Superpriority Revolving/Term A Credit Agreement (the “RCF/TLA Credit Agreement”), providing for:

a superpriority “first out” series A revolving credit facility with original commitments of approximately $489 million (the “Series A Revolving Credit Facility”);

a superpriority “second out” series B revolving credit facility with original commitments of approximately $467 million (the “Series B Revolving Credit Facility”, and together with the Series A Revolving Credit Facility, the “Lumen Revolving Credit Facilities”); and

a superpriority secured term loan facility in the amount of approximately $377 million (the “Lumen TLA”).

Interest on borrowings under the RCF/TLA Credit Agreement is payable at the end of each interest period at a rate equal to, at Lumen’s option:

for the Series A Revolving Credit Facility, term SOFR (subject to a 2.00% floor) plus 4.00% for term SOFR loans or a base rate plus 3.00% for base rate loans;

for the Series B Revolving Credit Facility, term SOFR (subject to a 2.00% floor) plus 6.00% for term SOFR loans or a base rate plus 5.00% for base rate loans; and

for the Lumen TLA, term SOFR (subject to a 2.00% floor) plus a 6.00% for term SOFR loans or a base rate plus 5.00% for base rate loans.

Lumen may prepay amounts outstanding under the Series B Revolving Credit Facility or Lumen TLA at anytime without premium or penalty. If no amounts are outstanding under the Series B Revolving Credit Facility, Lumen may prepay amounts outstanding under the Series A Revolving Credit Facility without premium or penalty.

Both of the Lumen Revolving Credit Facilities mature on June 1, 2028 (in each case subject to a springing maturity in certain circumstances). The Lumen TLA matures on June 1, 2028 and requires Lumen to make quarterly amortization payments of 1.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions.

As of December 31, 2025, no borrowings were outstanding under Lumen’s (i) Series A Revolving Credit Facility, with commitments of approximately $489 million, or (ii) Series B Revolving Credit Facility, with commitments of approximately $465 million.

Superpriority Term B Credit Agreement

On the TSA Effective Date, Lumen, as borrower, the lenders party thereto, Wilmington Trust, National Association (“WTNA”), as administrative agent, and Bank of America, as collateral agent, entered into a Superpriority Term B Credit Agreement (the “TLB Credit Agreement”), providing for:

a superpriority secured term loan facility in a principal amount of approximately $1.6 billion maturing April 15, 2029 (the “Lumen TLB-1”); and

a superpriority secured term loan facility in a principal amount of approximately $1.6 billion maturing April 15, 2030 (the “Lumen TLB-2”, and together with the Lumen TLB-1, the “Lumen TLB”).

Interest on borrowings under the TLB Credit Agreement is payable at the end of each interest period at a rate equal to, at Lumen’s option, adjusted term SOFR (subject to a 0% floor) plus 2.35% for term SOFR loans or a base rate plus 1.35% for base rate loans.
The Lumen TLB requires Lumen to make quarterly amortization payments of 0.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions. Amounts outstanding under the Lumen TLB may be prepaid at any time without premium or penalty.

Lumen Former Facilities

In connection with entering into the RCF/TLA Credit Agreement, all revolving commitments under Lumen’s amended and restated credit agreement dated January 31, 2020 (the “Former Parent Facilities”) were terminated and all of the debt issued thereunder was repaid as of December 31, 2025.

Level 3 Credit Agreements

Credit Agreement dated March 22, 2024

On the TSA Effective Date, Level 3 Financing, as borrower, Level 3 Parent, LLC. the lenders party thereto and WTNA, as administrative agent and collateral agent, entered into the Original Level 3 Credit Agreement, providing for:

a secured term B-1 loan facility in the principal amount of approximately $1.2 billion maturing April 15, 2029; and

a secured term B-2 loan facility in the principal amount of approximately $1.2 billion maturing April 15, 2030.

Pursuant to the First Credit Facilities Transactions, Level 3 Financing refinanced all of the outstanding secured Term Loan B-1 facilities and secured Term Loan B-2 facilities under the Original Level 3 Credit Agreement under its new secured Term Loan B-3 facility. Pursuant to the Second Credit Facilities Transactions, Level 3 Financing refinanced all of the outstanding secured Term Loan B-3 facilities under the Existing Level 3 Credit Agreement under its new secured Term Loan B-4 facility.

As of December 31, 2025, Level 3 Financing had $2.4 billion of non-amortizing secured Term Loan B-4 outstanding under the term loan facility established by the Level 3 Credit Agreement.

Borrowings under the Term Loan B-4 facility will be, at Level 3 Financing’s option, either (i) the base rate (which is the highest of (x) the overnight federal funds rate, plus 0.50%, (y) the prime rate on such day, and (z) the one-month SOFR published on such date, plus 1.00%), plus an applicable margin, or (ii) one-, three- or six-month SOFR, plus an applicable margin. The applicable margin for SOFR loans under the Term Loan B-4 will be 3.25%. The Term Loan B-4 is subject to a SOFR floor of 0.00%.

Level 3 Financing may voluntarily prepay loans or reduce commitments under the Level 3 Credit Agreement, in whole or in part, subject to minimum amounts, with prior notice, but without premium or penalty (other than a 1.00% premium on any prepayment in connection with a repricing transaction prior to March 29, 2026). Level 3 Financing is required to prepay borrowings under the term loan facility with 100% of the net cash proceeds of certain asset sales and 100% of the net cash proceeds of certain debt issuances, in each case subject to certain exceptions.

Level 3 Former Facility

In connection with entering into the Original Level 3 Credit Agreement, all of the indebtedness issued under Level 3 Financing’s amended and restated credit agreement dated as of November 29, 2019 (the “Former Level 3 Facility”) was repaid as of December 31, 2025.
Senior Notes of Lumen and its Subsidiaries

The Company’s consolidated indebtedness related to the senior notes of Lumen and its subsidiaries as of December 31, 2025 included:

superpriority senior secured notes issued by Lumen;

first and second lien secured notes issued by Level 3 Financing; and

senior unsecured notes issued by Lumen, Level 3 Financing, Qwest, and Qwest Capital Funding, Inc.

All of these notes carry fixed interest rates and all principal is due on the notes’ respective maturity dates, which rates and maturity dates are summarized in the table above.

Except for a limited number of senior notes issued by Qwest Corporation, the issuer generally can redeem the notes, at its option, in whole or in part, (i) pursuant to a fixed schedule of pre-established redemption prices, (ii) pursuant to a “make whole” redemption price, or (iii) under certain other specified limited conditions.

Revolving Letters of Credit

We use various financial instruments in the normal course of business. These instruments include letters of credit, which are conditional commitments issued on our behalf in accordance with specified terms and conditions. Lumen may draw letters of credit under (i) an uncommitted $225 million revolving letter of credit facility and (ii) the Lumen Revolving Credit Facilities.

As of December 31, 2025, we had $234 million of undrawn letters of credit outstanding, (i) $232 million of which were issued under the Lumen Revolving Credit Facilities and (ii) $2 million of which were issued under a separate facility maintained by Lumen subsidiaries (the full amount of which is collateralized by cash that is reflected on our consolidated balance sheets as restricted cash within Other assets, net).

Certain Guarantees and Security Interests

Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement are unsecured, but certain of Lumen’s subsidiaries have provided an unconditional guarantee of payment of Lumen’s obligations (such entities, the “Lumen Guarantors”) and certain of such guarantees are secured by a lien on substantially all of the assets of the applicable Lumen Guarantors. Level 3 Parent, Level 3 Financing and certain of Level 3 Financing’s subsidiaries have provided an unconditional guarantee of payment of Lumen’s obligations under each of its Series A Revolving Credit Facility of up to $150 million and its Series B Revolving Credit Facility of up to $150 million, in each case secured by a lien on substantially all of their assets (such entities, the “Level 3 Collateral Guarantors”). The guarantee by the Level 3 Collateral Guarantors may be reduced or terminated under certain circumstances. Qwest Corporation and certain of its subsidiaries have provided an unsecured guarantee of collection of Lumen’s obligations under the Revolving Credit Facilities and Lumen TLA (such entities, the “Qwest Guarantors”).

Lumen’s obligations under the Superpriority Term Loan B Credit Agreement are unsecured. The term loans issued under this agreement are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement.

Level 3 Financing’s obligations under the Level 3 Credit Agreement are secured by a first priority lien on substantially all of its assets. In addition, the other Level 3 Collateral Guarantors have provided a guarantee of Level 3 Financing’s obligations under the Level 3 Credit Agreement secured by a lien on substantially all of their assets.
Lumen’s superpriority secured senior notes are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement (subject, in certain cases, to receipt of necessary regulatory approvals). Level 3 Financing’s obligations under its first priority lien notes are secured by a first lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals), and are guaranteed by the other Level 3 Collateral Guarantors (or, for certain such guarantors, for certain notes, will be guaranteed upon the receipt of required regulatory approvals) on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement. Level 3 Financing’s obligations under its second lien notes are secured by a second lien on substantially all of its assets, and are guaranteed by the other Level 3 Collateral Guarantors on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement, except the lien securing such guarantees is a second lien.

Lumen's reimbursement obligations under its outstanding letters of credit are secured by guarantees issued by certain of its subsidiaries.

Level 3 Financing's obligations under its unsecured notes are guaranteed on an unsecured basis by the same affiliated entities that guarantee the Level 3 Credit Agreement and secured notes. The senior unsecured notes issued by Qwest Capital Funding, Inc. are guaranteed by its parent, Qwest Communications International Inc.

Covenants

Lumen

Under its Superpriority Revolving/Term Loan A Credit Agreement, Lumen may not permit:

its maximum total net leverage ratio to exceed 5.50 to 1.00 with respect to each fiscal quarter ending after December 31, 2024 and further stepping down to 5.25 to 1.00 with respect to each fiscal quarter ending after December 31, 2025; or

its interest coverage ratio as of the last day of any test period to be less than 2.00 to 1.00.

Lumen’s superpriority credit agreements and superpriority senior secured notes contain various representations and warranties and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on our ability to declare or pay dividends, repurchase stock, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, engage in transactions with our affiliates, dispose of assets and merge or consolidate with other persons.

Lumen’s senior unsecured notes were issued under four separate indentures. These indentures restrict Lumen’s ability to (i) incur, issue or create liens upon its property and (ii) consolidate with or merge into, or transfer or lease all or substantially all of its assets to, any other party.

Under certain circumstances in connection with a “change of control” of Lumen, Lumen will be required to make an offer to repurchase substantially all of these senior notes at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest.

Level 3 Financing

The Level 3 Credit Agreement and Level 3 Financing's first and second lien secured notes and unsecured notes contain various representations and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on their ability to declare or pay dividends, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, dispose of assets, and merge or consolidate with other persons. Also, under certain circumstances in connection with a “change of control” of Level 3 Parent or Level 3 Financing, Level 3 Financing will be required to make an offer to repurchase each series of its outstanding senior notes at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest.
Qwest Corporation and Qwest Capital Funding, Inc.

The senior notes of Qwest Corporation were issued under indentures dated April 15, 1990 and October 15, 1999. These indentures contain restrictions on the incurrence of liens and the consummation of certain transactions substantially similar to the above-described covenants in the indentures governing Lumen’s senior unsecured notes (but contain no mandatory repurchase provisions). The senior notes of Qwest Capital Funding, Inc. were issued under an indenture dated June 29, 1998 containing terms substantially similar to those set forth in Qwest Corporation's indentures.

Compliance

As of December 31, 2025, Lumen Technologies, Inc. believes it and its subsidiaries were in compliance with the provisions and financial covenants in their respective material debt agreements in all material respects.

Guarantees

Lumen does not guarantee the debt of any unaffiliated parties, but, as noted above, as of December 31, 2025, certain of its key subsidiaries have guaranteed on either a secured or unsecured basis (i) Lumen's debt outstanding under its superpriority credit agreements, its superpriority senior secured notes and unsecured senior notes issued by certain other subsidiaries and its $225 million letter of credit facility and (ii) the outstanding term loans, senior secured notes and senior unsecured notes issued by certain other subsidiaries. As further noted above, several of the subsidiaries guaranteeing these obligations have pledged substantially all of their assets to secure certain of their respective guarantees.

Subsequent Events

Senior Secured Notes

On January 9, 2026, Level 3 Financing, Inc. issued an additional $650 million aggregate principal amount of its 8.500% Senior Notes due 2036. Level 3 Financing used the net proceeds from this offering, to fund the repurchase of its outstanding Second Lien Notes.

The following table sets forth the aggregate principal amount of each series of Second Lien Notes repurchased as part of this transaction:

During the second quarter of 2023, we donated our Monroe, Louisiana campus and leased back a portion thereof. This donation resulted in a $101 million loss recognized for the year ended December 31, 2023.

As of December 31, 2025, we classified certain property, plant and equipment, net as held for sale and discontinued recording depreciation on the disposal group. See Note 2 — Divestitures.

We recorded depreciation expense of $1.7 billion, $1.9 billion and $1.9 billion for the years ended December 31, 2025, 2024 and 2023, respectively.
Asset Retirement Obligations

As of December 31, 2025 and 2024, our asset retirement obligations consisted primarily of estimated future costs of removing equipment from leased properties and estimated future costs of properly disposing of asbestos and other hazardous materials upon remodeling or demolishing buildings.

Severance
Note 10 — Severance

Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workloads due to reduced demand for certain services.

During April 2024, we further reduced our workforce by approximately 6% as a part of our efforts to change our workforce composition to reflect our ongoing transformation and cost reduction opportunities that align with our shapeshifting and focus on our strategic priorities. As a result of this plan, we incurred severance and related costs of approximately $103 million during the second quarter of 2024. We have not incurred, and do not expect to incur, any material impairment or exit costs related to either of these plans.

We report severance liabilities within accrued expenses and other liabilities - salaries and benefits in our consolidated balance sheets and report severance expenses in selling, general and administrative expenses in our consolidated statements of operations. As described in Note 16 — Segment Information, we do not allocate these severance expenses to our segments.

Employee Benefits
Note 11 — Employee Benefits

Pension, Post-Retirement, and Other Post-Employment Benefits

We sponsor various defined benefit pension plans (qualified and non-qualified) which, in the aggregate, cover a substantial portion of our employees. Pension benefits for participants of the Lumen Combined Pension Plan ("Combined Pension Plan") who are represented by a collective bargaining agreement are based on negotiated schedules. All other participants' pension benefits are based on each individual participant's years of service and compensation. We also maintain non-qualified pension plans for certain current and former highly compensated employees. We maintain post-retirement benefit plans that provide health care and life insurance benefits for certain eligible retirees. We also provide other post-employment benefits for certain eligible former employees. We use a December 31 measurement date for all our plans.

Pension Benefits

United States funding laws require a company with a pension shortfall to fund the annual cost of benefits earned in addition to a seven-year amortization of the shortfall. Our funding policy for our Combined Pension Plan is to make contributions with the objective of accumulating ample assets to pay all qualified pension benefits when due under the terms of the plan. The accounting unfunded status of the Combined Pension Plan was $559 million and $615 million as of December 31, 2025 and 2024, respectively.

We made no voluntary cash contributions to the trust for the Combined Pension Plan in 2025. In 2024, we made a voluntary cash contribution of $170 million to the trust for the Combined Pension Plan. We paid $4 million of benefits directly to participants of our non-qualified pension plans in both 2025 and 2024.

Benefits paid by the Combined Pension Plan are paid through a trust that holds all the Plan's assets. The amount of required contributions to the Combined Pension Plan in 2026 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. Based on current laws and circumstances, we do not believe we are required to make any contributions to the Combined Pension Plan in 2026. We estimate that in 2026 we will pay approximately $4 million of benefits directly to participants of our non-qualified pension plans.

We recognize in our consolidated balance sheets the funded status of the legacy Level 3 Parent, LLC qualified defined benefit post-retirement plan. This plan was fully funded as of December 31, 2025 and 2024. Additionally, as previously mentioned, we sponsor unfunded non-qualified pension plans for certain current and former highly-compensated employees. The net unfunded status of our non-qualified pension plans was $29 million and $30 million for the years ended December 31, 2025 and 2024, respectively. Due to the insignificant impact of these pension plans on our consolidated financial statements, we have predominantly excluded them from the remaining employee benefit disclosures in this Note, unless otherwise specifically stated.

Post-Retirement Benefits

Our post-retirement benefit plans provide post-retirement benefits to qualified retirees and allow certain participants to receive benefits at no or reduced cost and other participants to receive benefits on a shared cost basis. The post-retirement benefits not paid by the trusts are funded by us and we expect to continue funding these post-retirement obligations as benefits are paid. The accounting unfunded status of our qualified post-retirement benefit plan was $1.7 billion as of both December 31, 2025 and 2024.

Assets in the post-retirement trusts were substantially depleted as of December 31, 2016; as of December 31, 2019 the Company ceased to pay certain post-retirement benefits through the trusts. No contributions were made to the post-retirement trusts in 2025, nor 2024. Benefits are paid directly by us with available cash. In 2025, we paid $172 million of post-retirement benefits, net of participant contributions and direct subsidies. In 2026, we currently expect to pay directly $181 million of post-retirement benefits, net of participant contributions and direct subsidies.

We anticipate our expected health care cost trend to range from 6.70% to 8.20% in 2026 and grading to 4.50% by 2032. Our post-retirement benefit cost, for certain eligible legacy Qwest retirees and certain eligible legacy CenturyLink retirees, is capped at a set dollar amount. Therefore, those health care benefit obligations are not subject to increasing health care trends after the effective date of the caps.
Expected Cash Flows

The Combined Pension Plan payments, post-retirement health care benefit payments and premiums, and life insurance premium payments are either distributed from plan assets or paid by us. The estimated benefit payments provided below are based on actuarial assumptions using the demographics of the employee and retiree populations and have been reduced by estimated participant contributions.

We utilize a full yield curve approach in connection with estimating the service and interest components of net periodic benefit expense by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flow.

The actuarial assumptions used to compute the net periodic benefit expense for our Combined Pension Plan and post-retirement benefit plans are based upon information available as of the beginning of the year, as presented in the following table.

Service costs for our Combined Pension Plan and post-retirement benefit plans are included in the cost of services and products and selling, general and administrative line items on our consolidated statements of operations and all other costs listed above are included in other income (expense), net on our consolidated statements of operations for the years ended December 31, 2025, 2024, and 2023. Additionally, a portion of the service cost is also allocated to certain assets under construction, which are capitalized and reflected as part of property, plant and equipment in our consolidated balance sheets. As a result of ongoing efforts to reduce our workforce, we recognized a one-time charge in our net periodic post-retirement benefit expense in 2024 of $2 million and in our net periodic pension expense in 2023 of $2 million, both for special termination benefit enhancements paid to certain eligible employees upon voluntary retirement.

Our pension plan contains provisions that allow us, from time to time, to offer lump sum payment options to certain former employees in settlement of their future retirement benefits. We record an accounting settlement charge, consisting of the recognition of certain deferred costs of the pension plan associated with these lump sum payments only if, in the aggregate, they exceed or are probable to exceed the sum of the annual service and interest costs for the plan’s net periodic pension benefit cost, which represents the settlement accounting threshold. As of December 31, 2025, the settlement threshold was not reached. In the event of workforce reductions in the future, the annual lump sum payments may trigger settlement accounting.

Plan Assets

We maintain plan assets for our Combined Pension Plan and certain post-retirement benefit plans. As previously noted, assets in the post-retirement benefit plan trusts were substantially depleted as of December 31, 2016. The fair value of post-retirement benefit plan assets was $1 million as of December 31, 2025, 2024 and 2023. Due to the insignificance of these assets on our consolidated financial statements, we have predominantly excluded them from the disclosures of plan assets in this Note, unless otherwise indicated.

The following table summarizes the change in the fair value of plan assets for the Combined Pension Plan:

 Combined Pension Plan
Years Ended December 31,
 202520242023
 (Dollars in millions)
Change in plan assets   
Fair value of plan assets at beginning of year$4,201 4,476 4,715

Benefits paid from plan assets(485)(552)(494)
Contributions— 170 — 
Fair value of plan assets at end of year$4,189 4,201 4,476 

The expected rate of return on plan assets is the long-term rate of return we expect to earn on the plan's assets, net of administrative expenses paid from plan assets. It is determined annually based on the strategic asset allocation and the long-term risk and return forecast for each asset class.

Our investment objective for the Combined Pension Plan assets is to achieve an attractive risk-adjusted return over time that will provide for the payment of benefits while minimizing the risk of large losses in funded status. We employ a liability-aware investment strategy designed to reduce the volatility of pension assets relative to pension liabilities. This strategy is evaluated frequently and is expected to evolve over time with changes in the funded status and other factors. Approximately 40% of plan assets is targeted to long-duration investment grade bonds and interest rate sensitive derivatives and 60% is targeted to diversified equity, fixed income and private market investments that are expected to outperform the liability with moderate funded status risk. At the beginning of 2026, our expected annual long-term rate of return on pension assets before consideration of administrative expenses is assumed to be 7.0%. Administrative expenses, including projected Pension Benefit Guaranty Corporation premiums, reduce the annual long-term expected return, net of administrative expenses, to 6.5%.
Permitted investments: Plan assets are managed consistent with the restrictions set forth by the Employee Retirement Income Security Act of 1974, as amended.

Fair value measurements: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We measure plan assets at fair value using a hierarchy that prioritizes observable inputs. For additional information on the fair value hierarchy, see Note 14 — Fair Value of Financial Instruments.

As of December 31, 2025, we used the following valuation techniques to measure fair value for assets. There were no changes to these methodologies during 2025:

Level 1 — Assets were valued using the closing price reported in the active market in which the individual security was traded. U.S. Treasury securities are valued at the bid price reported in an active market in which the security is traded. Variation margin due from/(to) brokers is valued at the expected next day cash settlement amount.

Level 2 — Assets were valued using quoted prices in markets that are not active, broker dealer quotations, and other methods by which all significant inputs were observable at the measurement date. Fixed income securities primarily utilize observable market information and are based on a spread to U.S. Treasury securities and consider yields available on comparable securities of issuers with similar credit ratings, the new issue market for similar securities, secondary trading markets and dealer quotes. Option adjusted spread models are utilized to evaluate fixed income securities that have early redemption features. Derivative securities traded over the counter are valued based on gains or losses due to fluctuations in indices, interest rates, foreign currency exchange rates, security prices or other underlying factors. Repurchase agreements are valued based on expected settlement per the contract terms.

Level 3 — Assets were valued using unobservable inputs where little or no market data exists at the measurement date. Valuation methods may consider a range of factors, including estimates provided by the investment entity.

The Combined Pension Plan's assets are invested in various asset categories utilizing multiple strategies and investment managers. Interests in commingled funds are fair valued using a practical expedient to the net asset value ("NAV") per unit (or its equivalent) of each fund. The NAV reported by the fund manager is based on the market value of the underlying investments owned by each fund, minus its liabilities, divided by the number of shares outstanding. Commingled funds can be redeemed at NAV, with a frequency that includes daily, monthly, quarterly, semi-annually and annually. These commingled funds include redemption notice periods between same day and 95 days. Investments in private funds, primarily limited partnerships, represent long-term commitments with a fixed maturity date and are also valued at NAV. The plan has unfunded commitments related to certain private fund investments, which in aggregate are not material to the plan. Valuation inputs for these private fund interests are generally based on assumptions and other information not observable in the market. Underlying investments held in funds are aggregated and are classified based on the fund mandate. Investments held in separate accounts are individually classified.
The table below presents the fair value of plan assets by category and the input levels used to determine those fair values as of December 31, 2025. It is important to note that the asset allocations do not include market exposures that are gained with derivatives. Investments include dividend and interest receivables, pending trades and accrued expenses.

Below is an overview of the asset categories and the underlying strategies used in the preceding tables:

(a) Investment grade bonds represent investments in U.S. Treasury securities, agencies, corporate bonds, mortgage-backed securities, asset-backed securities and commercial mortgage-backed securities.

(b) High yield bonds represent investments in below investment grade fixed income securities.

(c) Emerging market bonds represent investments issued by governments and other entities located in emerging countries.

(d) U.S. stocks represent investments in stocks of U.S. based companies.

(e) Non-U.S. stocks represent investments in companies based in developed countries outside the U.S.

(f) Emerging market stocks represent investments in stocks of companies located in emerging markets.

(g) Private equity represents non-public investments in domestic and foreign buyout and venture capital funds. Private equity funds are primarily structured as limited partnerships and are valued according to the valuation policy of each partnership, subject to prevailing accounting and other regulatory guidelines.

(h) Private debt represents non-public investments in performing and distressed credits.

(i) Market neutral hedge funds hold investments in a diversified mix of instruments that are intended in combination to exhibit low correlations to market fluctuations. These investments are typically combined with futures to achieve uncorrelated excess returns over various markets.

(j) Directional hedge funds represent investments that may exhibit somewhat higher correlations to market fluctuations than the market neutral hedge funds.

(k) Real estate represents investments in a diversified portfolio of real estate properties.
(l) Derivatives include exchange traded futures contracts as well as privately negotiated over the counter contracts. The market values represent gains or losses that occur due to differences between stated contract terms and fluctuations in underlying market instruments.

(m) Repurchase agreements and other obligations includes contracts where the security owner sells a security with the agreement to buy it back at a future date and price. Other obligations include obligations to repay cash collateral held by a plan, net liability for investment purchases pending settlement, and accrued plan expenses.

(n) Cash equivalents and short-term investments represent investments that are used in conjunction with derivatives positions or are used to provide liquidity for the payment of benefits or other purposes.

Derivative instruments: The plan uses exchange‑traded futures and centrally cleared/OTC swaps primarily to align interest‑rate exposure with liabilities and to efficiently maintain equity exposure. Fair values of these instruments are included within the fair value hierarchy.

Concentrations of risk: Investments, in general, are exposed to various risks, such as significant world events, interest rate, credit, foreign currency and overall market volatility risk. These risks are managed by broadly diversifying assets across numerous asset classes and strategies with differing expected returns, volatilities and correlations. Risk is also broadly diversified across numerous market sectors and individual companies. Financial instruments that potentially subject the plans to concentrations of counterparty risk consist principally of investment contracts with high quality financial institutions. These investment contracts are typically collateralized obligations or are actively managed, limiting the amount of counterparty exposure to any one financial institution. Although the investments are well diversified, the value of plan assets could change materially depending upon the overall market volatility, which could affect the funded status of the plan.

Certain gains and losses are allocated between assets sold during the year and assets still held at year-end based on transactions and changes in valuations that occurred during the year. These allocations also impact our calculation of net acquisitions and dispositions.

For the year ended December 31, 2025, the investment program produced actual gains on Combined Pension Plan assets of $473 million as compared to expected returns of $254 million, for a difference of $219 million. For the year ended December 31, 2024, the investment program produced actual gains on Combined Pension Plan assets of $107 million as compared to the expected returns of $272 million, for a difference of $165 million. The short-term annual returns on plan assets will almost always be different from the expected long-term returns and the plans could experience net gains or losses, due primarily to the volatility occurring in the financial markets during any given year.

Other Benefit Plans

Medicare Prescription Drug, Improvement and Modernization Act of 2003

We sponsor post-retirement health care plans with several benefit options that provide prescription drug benefits that we deem actuarially equivalent to or exceeding Medicare Part D. We recognize the impact of the federal subsidy received under the Medicare Prescription Drug, Improvement and Modernization Act of 2003 in the calculation of our post-retirement benefit obligation and net periodic post-retirement benefit expense.

Health Care and Life Insurance

We provide health care and life insurance benefits to essentially all our active employees. We are largely self-funded for the cost of the health care plan. Our health care benefit expense for current employees was $336 million, $281 million and $288 million for the years ended December 31, 2025, 2024 and 2023, respectively. Union-represented employee benefits are based on negotiated collective bargaining agreements. Employees contributed $71 million, $79 million, $89 million for the years ended December 31, 2025, 2024 and 2023, respectively. Our group basic life insurance plans are fully insured and the premiums are paid by us.
401(k) Plans

We sponsor a qualified defined contribution plan covering substantially all our U.S. employees. Under this plan, employees may contribute a percentage of their annual compensation up to certain maximums, as defined by the plan and by the Internal Revenue Service. Currently, we match a percentage of employee contributions in cash. As of December 31, 2025 and 2024, the assets of the plan included approximately 7 million and 8 million shares of our common stock, all of which were the result of the combination of previous employer match and participant directed contributions. We recognized expenses related to this plan of $80 million, $82 million and $87 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Deferred Compensation Plans

We sponsor non-qualified deferred compensation plans for various groups that included certain of our current and former highly compensated employees. The value of liabilities related to these plans was not significant.

Subsequent Event
In January 2026, we made a voluntary contribution of $101 million to the trust for the Combined Pension Plan.

Stock-based Compensation
Note 12 — Stock-Based Compensation

We maintain an equity incentive program that allows our Board of Directors (through its Human Resources and Compensation Committee or a senior officer acting under delegated authority) to grant incentives to certain employees and outside directors in one or more forms, including: incentive and non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and market and other equity-based awards.

Restricted Stock Awards and Restricted Stock Unit Awards

We grant equity based restricted stock and restricted stock units that contain service only conditions for vesting (“Service Awards”), awards that contain both service and market conditions for vesting (“Market Awards”) and awards that contain both service and performance conditions for vesting (“Performance Awards”). The fair value of Service Awards is based upon the closing stock price on the accounting grant date and the awards generally vest over periods ranging from one to four years. The fair value of Market Awards is determined using Monte-Carlo simulations and the awards vest over periods up to three years. The number of shares ultimately earned for Market Awards is typically based upon our total shareholder return as compared to the return of selected peer companies and can range between 0% and 200% of the target number of shares for the award. The fair value of Performance Awards is based upon the closing stock price on the accounting grant date; however, the award value may increase, or decrease based upon the extent to which the performance conditions are satisfied. Performance Awards vest over periods of up to three-years and specify a target number of shares for the award. The recipient ultimately can receive between 0% and 200% of the target number of shares depending upon the extent to which the performance conditions are satisfied.

The following table summarizes activity involving restricted stock and restricted stock unit awards for the year ended December 31, 2025:

During 2025, we granted 19.0 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $5.10. During 2024, we granted 14.3 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $1.69. During 2023, we granted 14.8 million shares of restricted stock and restricted stock unit awards at a weighted-average price of $1.85. The total fair value of restricted stock and restricted stock unit awards that vested during 2025, 2024 and 2023, was $44 million, $27 million and $21 million, respectively. We do not estimate forfeitures but recognize them as they occur.

Compensation Expense and Tax Benefit

For Service Awards that vest ratably over the service period, we recognize compensation expense on a straight-line basis over the requisite service period for the entire award. For Service Awards that vest at the end of the service period and for Market Awards, we recognize compensation expense over the service period. For our Performance Awards, we recognize compensation expense over the service period and based upon the expected performance outcome, until the final performance outcome is determined. Total compensation expense for all stock-based payment arrangements for the years ended December 31, 2025, 2024 and 2023, was $48 million, $29 million and $52 million, respectively. Our tax benefit recognized in the consolidated statements of operations for our stock-based payment arrangements for the years ended December 31, 2025, 2024 and 2023, was $12 million, $7 million and $12 million, respectively. As of December 31, 2025, there was $83 million of total unrecognized compensation expense related to our stock-based payment arrangements, which we expect to recognize over a weighted-average period of 1.5 years.

Fair Value of Financial Instruments
Note 14 — Fair Value of Financial Instruments

Our financial instruments consist of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, long-term debt (excluding finance lease and other obligations), certain equity investments and certain indemnification obligations. Due primarily to their short-term nature, the carrying amounts of our cash, cash equivalents, restricted cash, accounts receivable and accounts payable approximate their fair values.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs using the below-described fair value hierarchy.

We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:
Input LevelDescription of Input
Level 1Observable inputs such as quoted market prices in active markets.

The effective tax rate for the year ended December 31, 2025 includes a $333 million favorable impact from statute of limitation releases on uncertain tax positions previously disclosed. The effective tax rate for December 31, 2024 includes a $135 million favorable impact from the exclusion of cancellation of debt income ("CODI") under Section 108 of the Internal Revenue Code. The effective tax rate for the year ended December 31, 2023 includes a $2.2 billion unfavorable impact of a non-deductible goodwill impairment and a $137 million favorable impact as a result of utilizing available capital losses generated by the sale of our Latin American business in 2022.

As of December 31, 2025, we have determined that a portion of our undistributed earnings in India are no longer permanently reinvested, resulting in the recognition of an immaterial deferred tax liability. We continue to assert that undistributed earnings of our subsidiaries in all other foreign jurisdictions are indefinitely reinvested.

Of the $2.1 billion and $2.8 billion net deferred tax liability as of December 31, 2025 and 2024, respectively, $2.3 billion and $2.9 billion is reflected as a long-term liability and $145 million and $96 million is reflected as a net noncurrent deferred tax asset, in other, net on our consolidated balance sheets as of December 31, 2025 and 2024, respectively.

Income taxes receivable as of December 31, 2025 and 2024, were $468 million and $483 million, respectively.

As of December 31, 2025, we had federal NOLs of approximately $982 million, net of expirations from limitations under Section 382 of the Internal Revenue Code and uncertain tax positions, for U.S. federal income tax purposes. We expect to use substantially all of these NOLs to reduce our future federal tax liabilities, although the timing of that use will depend upon our future earnings and future tax circumstances. Our ability to use these NOLs is subject to annual limits imposed by Section 382. If unused, approximately $570 million of pre-2018 NOLs will expire between 2027 and 2031.

As of December 31, 2025, we had state NOLs of $11 billion (net of uncertain tax positions). Our ability to use these NOLs is subject to annual limits under state law.

We establish valuation allowances when necessary to reduce the deferred tax assets to amounts we expect to realize. As of December 31, 2025, we established a valuation allowance of $328 million as it is more likely than not that this amount of NOLs will not be utilized prior to expiration. Our valuation allowance as of December 31, 2025 and 2024 is primarily related to NOLs. This valuation allowance decreased by $15 million during 2025, primarily due to changes in our state NOL carryforwards.
A reconciliation of the change in our gross unrecognized tax benefits (excluding both interest and any related federal benefit) for the years ended December 31, 2025 and 2024 is as follows:
20252024
 (Dollars in millions)
Unrecognized tax benefits at beginning of year$1,263 1,424 
Increase (decrease) in tax positions of prior periods netted against deferred tax assets(4)
Decrease in tax positions taken in the current year(7)(64)
Increase in tax positions taken in the prior year65 
Decrease due to payments/settlements(1)— 
Decrease from the lapse of statute of limitations(394)(158)
Unrecognized tax benefits at end of year$866 1,263 

As of December 31, 2025, the total amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate was $653 million. The unrecognized tax benefits also include tax positions that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes, which would not impact the effective tax rate but could impact cash tax amounts payable to taxing authorities.

Our policy is to reflect interest expense associated with unrecognized tax benefits in income tax (benefit) expense. We had accrued interest (presented before related tax benefits) of approximately $306 million and $217 million as of December 31, 2025 and 2024, respectively.

We, or at least one of our subsidiaries, file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2004. The Internal Revenue Service and state and local taxing authorities reserve the right to audit any period where NOLs are available.

Based on our current assessment of various factors, including (i) the potential outcomes of these ongoing examinations, (ii) the expiration of statute of limitations for specific jurisdictions, (iii) the negotiated settlement of certain disputed issues, and (iv) the administrative practices of applicable taxing jurisdictions, it is reasonably possible that the related unrecognized tax benefits for uncertain tax positions previously taken may decrease by up to $287 million within the next 12 months. The actual amount of such decrease, if any, will depend on several future developments and events, many of which are outside our control.

In July 2025, the U.S. enacted the “One, Big Beautiful Bill Act” (the “OBBBA”), which permanently allows 100% bonus depreciation, immediate expensing for domestic R&D, and favorable changes to interest expense limitations. These provisions did not have a material impact on our 2025 effective tax rate but significantly reduced our federal income tax liability. The Company filed a refund claim for $400 million of federal estimated income taxes in July 2025 that it anticipates receiving in the first half of 2026.

The OECD has issued Pillar Two model rules introducing a new global minimum corporate tax of 15% for tax years effective after December 31, 2023. While the U.S. has not adopted Pillar Two legislation, certain countries in which we operate have already adopted legislation to implement Pillar Two. On January 5, 2026, the OECD announced the Side-by-Side ("SbS") package, implemented as administrative guidance modifying the operation of Pillar Two rules, which would fully exempt U.S.-parented groups from the application certain Pillar Two top-up taxes. The SbS package also extends the current Transitional Country-by-Country Reporting ("CbCR") Safe Harbor by one year, through the end of fiscal year of 2027. The Pillar Two rules have increased our compliance requirements but did not materially impact our 2025 results. We continue to monitor evolving global and domestic tax legislation and administrative guidance.

Segment Reporting [Abstract]  
Segment Information
Note 16 — Segment Information

Our business is managed based on customer-facing sales channels to align with how we support our customers. Our chief operating decision maker ("CODM"), who is our CEO, makes decisions and assesses the performance of the Company reviewing two segments: Business and Mass Markets. Our reportable segments have not been aggregated.
Under our Business segment, we provide products and services to meet the needs of our enterprise and wholesale customers under five distinct sales channels — Large Enterprise, Mid-Market Enterprise, Public Sector, Wholesale and International and Other. For Business segment revenue, we report the following product categories: Grow, Nurture, Harvest and Other, in each case through the sales channels outlined above. The Business segment included the results of our EMEA business prior to the sale on November 1, 2023.

Under our Mass Markets segment, we provide products and services to residential and small business customers. We report the following product categories: Fiber Broadband, Other Broadband, and Voice and Other.

See detailed descriptions of these product and service categories in Note 4 — Revenue Recognition.

As described in more detail below, our segments are managed based on the direct costs of providing services to their customers and directly associated headcount and non-headcount operating expenses. Shared costs are managed separately and included in "other unallocated expense" in the table included below under the heading "— Revenue and Expenses." As referenced above, we reclassified certain prior period amounts to conform to the current period presentation. See Note 1 — Background and Summary of Significant Accounting Policies for additional detail on these changes. The CODM uses adjusted EBITDA as the key indicator in assessing performance and allocating resources for both the Business segment and Mass Markets segment.

The following tables summarize our segment results for 2025, 2024 and 2023 based on the segment categorization we were operating under as of December 31, 2025.

Revenue and Expenses

Our segment revenue includes all revenue from our two segments as described in more detail above. Our segment revenue is based upon each customer's classification. We report our segment revenue based upon all services provided to that segment's customers. Our segment expenses include (i) specific cost of service expenses incurred as a direct result of providing services and products to segment customers, (ii) headcount costs, which primarily includes salaries, commissions, and group insurance, and (iii) non-headcount costs, which primarily include legal and other professional fees, marketing and advertising expenses, other network-related expenses, and external commissions. We have not allocated assets or debt to specific segments.

The following items are excluded from our segment results, because they are centrally managed and not monitored by or reported to our chief operating decision maker by segment:

network expenses not incurred as a direct result of providing services and products to segment customers and centrally managed expenses such as Finance, Human Resources, Legal, Marketing, Product Management, and IT, all of which are reported as "other unallocated expense" in the table below;

depreciation and amortization expense;

goodwill or other impairments;

interest expense;

stock-based compensation;

other income and expense items; and

income tax expense.

Commitments, Contingencies and Other Items
Note 17 — Commitments, Contingencies and Other Items

We are subject to various claims, legal proceedings and other contingent liabilities, including the matters described below, which individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows.

We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Subject to these limitations, as of December 31, 2025 and December 31, 2024, we had accrued $71 million and $78 million, respectively, in the aggregate for our litigation and non-income tax contingencies, which is included in Other current liabilities or Other liabilities on our consolidated balance sheets as of such dates. Although we quantify our exposure for certain matters below, we cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $71 million accrual as of December 31, 2025 due to the inherent uncertainties and speculative nature of contested proceedings. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.

In this Note, a reference to a "putative" class action means a class has been alleged, but not certified, in that matter.
Principal Proceedings

Houser Shareholder Suit

Lumen and certain of its current and former officers and directors were named as defendants in a putative shareholder class action lawsuit filed on June 12, 2018 in the Boulder County District Court of the state of Colorado, captioned Houser et al. v. CenturyLink, et al. The original complaint asserted claims on behalf of a putative class of former Level 3 Communications, Inc. ("Level 3") shareholders who became CenturyLink, Inc. shareholders as a result of our acquisition of Level 3. It alleged that the proxy statement provided to the Level 3 shareholders failed to disclose various material information, including information about strategic revenue, customer loss rates, and customer account issues, among other items. The original complaint sought damages, costs and fees, rescission, rescissory damages, and other equitable relief. In May 2020, the court dismissed the original complaint. The plaintiffs appealed that decision, and in March 2022, the appellate court affirmed the district court's order in part and reversed it in part. It then remanded the case to the district court for further proceedings. The plaintiffs filed an amended complaint asserting the same claims and prayer for relief, and we filed a motion to dismiss. The court granted our motion to dismiss in May 2023 and the plaintiffs appealed that dismissal. In August 2024, the appellate court set aside the trial court's dismissal. In October 2024, we filed a petition with the Colorado Supreme Court seeking a review of the appellate court's decision, and the petition for review was granted.

Lead-Sheathed Cable Litigation

Disclosure Litigation

On September 15, 2023, a purported shareholder of Lumen filed a putative class action complaint originally captioned Glauber, et al. v. Lumen Technologies (now captioned In re Lumen Technologies, Inc. Securities Litigation II, Case 3:23-cv-01290), in the U.S. District Court for the Western District of Louisiana. The complaint alleged that Lumen and certain of its current and former officers violated the federal securities laws by omitting or misstating material information related to Lumen’s responsibility for environmental degradation allegedly caused by the lead sheathing of certain telecommunications cables. The court appointed lead plaintiffs who filed an amended complaint, seeking money damages, attorneys’ fees and costs, and other relief. On March 31, 2025, the court granted Lumen's motion to dismiss plaintiffs' claims with prejudice. On April 30, 2025, the plaintiffs filed an appeal which is captioned McLemore v. Lumen Technologies, Case 25-30264, in the U.S. Court of Appeals for the Fifth Circuit. On January 30, 2026, the Fifth Circuit reversed on prejudice only and modified the dismissal to be without prejudice.

Derivative Litigation

On June 11, 2024, a purported shareholder of Lumen filed a shareholder derivative complaint on behalf of Lumen captioned Brown v. Johnson, et al., Case 3:24-cv-00798-TAD-KDM, in the U.S. District Court for the Western District of Louisiana. The complaint alleges claims for breach of fiduciary duty, violations of the federal securities laws, and other causes of action against current and former officers and directors of Lumen relating to placement or presence of lead-sheathed telecommunications cables. The complaint seeks damages, injunctive relief, and attorneys' fees. Substantially similar derivative cases have been filed as follows: (i) on August 9, 2024, Pourarian v. Johnson, et al., Case 3:24-cv-01071-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (ii) on September 9, 2024, Capistrano v. Johnson, et al., Case 3:24-cv-01234-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (iii) on September 16, 2024, Vogel v. Perry, et al., Case 2024-3360 in the 4th Judicial District Court for the Parish of Ouachita, State of Louisiana, subsequently removed on September 17, 2024 to the U.S. District Court for the Western District of Louisiana as Case 3:24-cv-01274-TAD-KMM; and (iv) on September 25, 2024, Murray v. Allen, et al., Case 3:24-cv-01320 in the U.S. District Court for the Western District of Louisiana. In April 2025, the court consolidated the Brown, Pourarian, Capistrano, and Murray actions and stayed the consolidated action pending further developments in In re Lumen Technologies, Inc. Securities Litigation II. In July 2025, the court similarly stayed the Vogel action.
Environmental Litigation

Parish of St. Mary

On July 9, 2024, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, Case 138575, asserting claims on behalf of all parishes, municipalities, and citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. The case was removed to the United States District Court Western District of Louisiana Lafayette Division, Case 6:24-CV-01001-RRS-DJA. On December 6, 2024, the plaintiffs voluntarily dismissed the class action complaint without prejudice. On December 13, 2024, St. Mary’s Parish along with other parishes, municipalities, and two individuals served a notice of intent to file citizen suit under the Louisiana Environmental Quality Act, asserting claims identical to the class action which the plaintiffs voluntarily dismissed. In April 2025, the Village of Parks (one of the municipalities which had served a notice of intent to file a citizen suit) served Lumen with a petition in an action captioned Village of Parks v. Lumen Technologies, Inc., Case 95026, in the 16th Judicial District Court for the Parish of St. Martin, State of Louisiana. The Village of Parks petition seeks damages and injunctive relief under Louisiana state law relating to the above-described allegations about lead-sheathed telecommunications cables.

Blum

On November 6, 2023, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, Case 137935, asserting claims on behalf of all citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T, BellSouth, Verizon, and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. The case has been removed to Federal Court in the United States District Court Western District of Louisiana Lafayette Division, Case 6:23-CV-01748. In December 2024, the plaintiffs filed an amended complaint and a motion for remand. In September 2025, the motion to remand was denied.

State Tax Suits

Since 2012, a number of Missouri municipalities have asserted claims in the Circuit Court of St. Louis County, Missouri, alleging that we and several of our subsidiaries have underpaid taxes. These municipalities are seeking, among other things, declaratory relief regarding the application of business license and gross receipts taxes and back taxes from 2007 to the present, plus penalties and interest. In a February 2017 ruling in connection with one of these pending cases, the court entered an order awarding the plaintiffs $4 million and broadening the tax base on a going-forward basis. We appealed that decision to the Missouri Supreme Court. In December 2019, it affirmed the circuit court's order in some respects and reversed it in others, remanding the case to the circuit court for further proceedings. The Missouri Supreme Court's decision reduced our exposure in the case. In a June 2021 ruling in one of the pending cases, another trial court awarded the cities of Columbia and Joplin approximately $55 million, plus statutory interest. On appeal, the Missouri Court of Appeals affirmed in part and reversed in part, vacated the judgment and remanded the case to the trial court with instructions for further proceedings consistent with the Missouri Supreme Court's decision. In July 2025, a settlement was reached with the cities of Columbia and Joplin.

FCRA Litigation

In November 2014, a putative class action complaint captioned Bultemeyer v. CenturyLink, Inc. was filed in the United States District Court for the District of Arizona, Case CV-14-02530-PHX-SPL, alleging violations of the Fair Credit Reporting Act (the "FCRA"). In February 2017, the case was dismissed for lack of standing. The plaintiff appealed and the Ninth Circuit reversed and remanded. Class certification was contested and ultimately granted in 2023. The Ninth Circuit denied Lumen’s request to appeal the class certification ruling. A jury trial was conducted in September 2024. The jury found that CenturyLink willfully violated the FCRA and awarded each class member $500 for statutory damages and $2,000 for punitive damages. The district court denied Lumen's post-trial motions for relief, and on October 16, 2024, Lumen filed an appeal which is captioned Bultemeyer v. CenturyLink, Inc., Case 24-6413, in the U.S. Court of Appeals for the Ninth Circuit. We have not accrued a contingent liability for this matter. While liability is possible, we have not determined it to be probable, and damages exposure, if any, is uncertain.
December 2018 Outage Proceedings

We experienced an outage on one of our transport networks that impacted voice, IP, 911, and transport services for some of our customers between the 27th and 29th of December 2018. We believe that the outage was caused by a faulty network management card from a third-party equipment vendor.

The FCC and four states initiated formal investigations. In November 2020, following the FCC's release of a public report on the outage, we negotiated a settlement which was disclosed by the FCC in December 2020. The amount of the settlement was not material to our financial statements.

In December 2020, the Staff of the Washington Utilities and Transportation Commission ("WUTC") filed a complaint against us based on the December 2018 outage, seeking penalties of approximately $7 million for alleged violations of Washington regulations and laws. The Washington Attorney General's office sought penalties of $27 million. Following trial, the WUTC issued an order imposing a penalty of approximately $1 million. On April 15, 2024, we appealed that decision to the Washington State Court of Appeals. In August 2025, the Court of Appeals denied the appeal. In September 2025, we filed a petition for review with the Washington State Supreme Court. In January 2026, the Washington State Supreme Court denied our petition for review.

Latin American Tax Indemnification Claims

In connection with the 2022 divestiture of our Latin American business, the purchaser assumed responsibility for the Brazilian tax claims described in our prior periodic reports filed with the SEC. However, we agreed to indemnify the purchaser for amounts paid with respect to the Brazilian tax claims. The value of this indemnification and others associated with the Latin American business divestiture are included in the indemnification amount as disclosed in Note 14 — Fair Value of Financial Instruments. In addition, there remain other pending proceedings in Brazil, Peru, and other Latin America countries, that, if upheld, could result in a reasonably possible loss of up to approximately $82 million in excess of the amount accrued as of December 31, 2025.

Huawei Network Deployment Investigations

Lumen has received requests from the following federal agencies for information relating to the use of equipment manufactured by Huawei Technologies Company ("Huawei") in Lumen’s networks.

DOJ. Lumen has received a civil investigative demand from the U.S. Department of Justice in the course of a False Claims Act investigation alleging that Lumen Technologies, Inc. and Lumen Technologies Government Solutions, Inc. failed to comply with certain specified requirements in federal contracts concerning their use of Huawei equipment.

FCC. The FCC’s Enforcement Bureau issued a Letter of Inquiry to Lumen Technologies, Inc. regarding its written certifications to the FCC that Lumen has complied with FCC rules governing the use of resources derived from the High Cost Program, Lifeline Program, Rural Health Care Program, E-Rate Program, Emergency Broadband Benefit Program, and the Affordable Connectivity Program. Under these programs, federal funds may not be used to facilitate the deployment or maintenance of equipment or services provided by Huawei, a company the FCC has determined poses a national security threat to the integrity of U.S. communications networks or the communications supply chain.

Team Telecom. The Committee for the Assessment of Foreign Participation in the United States Telecommunications Service Sector (comprised of the U.S. Attorney General, and the Secretaries of the Department of Homeland Security, and the Department of Defense), commonly referred to as Team Telecom, issued questions and requests for information relating to Lumen’s FCC licenses and its use of Huawei equipment.
Marshall Fire Litigation

On December 30, 2021, a wildfire referred to as the Marshall Fire ignited near Boulder, Colorado. The Marshall Fire killed two people, and it burned thousands of acres, including entire neighborhoods. Approximately 300 lawsuits seeking substantial monetary relief have been filed naming as defendants our affiliate Qwest Corporation, an additional telecommunications company, and certain power companies. The complaints involving Qwest have been consolidated with Kupfner et al., v. Public Service Company of Colorado, et al., Case 2022-cv-30195 pending in Colorado District Court, Boulder, Colorado. In September 2025, the court vacated the trial date because the defendants reached agreements in principle to settle with virtually all of the plaintiffs, subject to final documentation. The court has held periodic status conferences and set a further status conference for February 26, 2026.

Minnesota State Income Tax Appeal

In May 2025, the Minnesota Department of Revenue issued an order (the "Order") denying the Company's petition for a separate allocation or separate apportionment of the taxable gain resulting from the 2022 divestiture of a portion of our incumbent local exchange carrier ("ILEC") business and making other minor adjustments. The Order seeks to assess additional income tax, penalties, and interest for the 2021 and 2022 tax years. On August 4, 2025, Lumen filed an appeal of the Order disputing this assessment, which is captioned Lumen Technologies, Inc. v. Commissioner of Revenue, Docket No. 9744-R., in the Minnesota Tax Court. The Company previously established an uncertain tax position for this item.

Other Proceedings, Disputes and Contingencies

From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, regulatory hearings relating primarily to our rates or services, actions relating to employee claims, tax issues, or environmental law issues, grievance hearings before labor regulatory agencies, miscellaneous third-party tort actions, or commercial disputes.

We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial within the next twelve months if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers.

We are subject to various foreign, federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $300,000 in fines and penalties. In addition, in the past we acquired companies that had installed lead-sheathed cables several decades earlier, or had operated certain manufacturing companies in the first part of the 1900s. Under applicable environmental laws, we could be named as a potentially responsible party for a share of the remediation of environmental conditions arising from the historical operations of our predecessors.

The outcomes of these other proceedings described under this heading are not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on us.

The matters listed in this Note do not reflect all our contingencies. The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings we currently consider insignificant may ultimately affect us materially.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
As a technology and communications company that globally transmits large amounts of information over our networks, we recognize the critical importance of maintaining the confidentiality, integrity and availability of information and systems under our control. Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise program to other key risk areas. We dedicate significant resources towards programs designed to identify, assess, manage, mitigate and respond to cybersecurity threats.

To identify, assess and mitigate cybersecurity risk, we have implemented a global information security management program that includes administrative, technical, and physical safeguards. This program seeks to identify, detect, protect against, and respond to threats to our information systems. Our security operations center provides advanced threat detection and response capabilities. We maintain an insider threat program to detect, investigate and mitigate insider threat risks to Lumen assets, data, services and personnel globally.

Our cybersecurity and privacy policies encompass information security, incident response procedures, and vendor management. Our risk management team works closely with our information technology, privacy, product, and operations departments to continuously evaluate emerging cyber risk as part of our overall risk management program. We monitor existing or proposed cybersecurity and privacy laws, regulations and guidance that are or may be applicable to us in the regions where we operate, including in the European Union and the United Kingdom where we are subject to the GDPR, as well as various other laws governing privacy rights, data protection and cybersecurity in other regions. As a U.S. government contractor, we are required to comply with extensive governmental regulations and standards regarding cyber security.

We periodically engage both internal and external auditors and consultants to assess and enhance our program and to assist in responding to cybersecurity incidents. Many of these independent external auditors and consultants are accredited under various information security standards, including those administered by the International Organization for Standardization and the PCI Security Standards Council. These engagements typically include penetration testing, third-party certifications, compliance assessments, audits, and assessments of vulnerabilities and emerging threats, as well as digital forensics and related work. We also periodically deploy our Internal Audit processes to conduct additional reviews and assessments. We also mutually exchange threat intelligence with government agencies, cyber analysis centers and cybersecurity associations.

As noted elsewhere in this annual report, we are materially reliant on a variety of third-party service providers to operate our business, which exposes us to the risk of cyber incidents impacting those providers’ systems. We have a vendor risk management program that assesses, manages and oversees risks associated with third-party service providers who have access to our data and systems. We engage in diligence, contracting or maintain ongoing monitoring for compliance with our cybersecurity standards, depending on our assessment of each provider's operational criticality and risk profile.

Despite our efforts to manage cybersecurity risks and prevent security incidents, (i) some of these attacks have resulted in security incidents (although thus far we do not believe that any of these incidents has resulted in or is reasonably likely to result in a material adverse effect on our business strategy, operating results, or financial condition) and (ii) future security incidents are likely (some of which could have a material adverse effect on our operating results or financial condition). See “Risk Factors” in Item 1A for a further discussion of cybersecurity risks and how they have affected or may affect us.
We maintain an Incident Response Playbook that provides a set of guidelines for our stakeholders to follow when handling any data incident. This playbook describes how we assess incidents and how our security team shares information about such incidents with others at Lumen, including senior leadership and, if warranted, with some or all members of our Board of Directors. These escalation provisions, together with our disclosure controls and procedures, are designed to facilitate appropriate representatives throughout the Company in their assessment of relevant incidents and any necessary public notifications.

Our Cybersecurity Incident Response Team (“CIRT”) is responsible for detecting and coordinating responses to appropriate security incidents. This team regularly assesses its internal communication plan and meet as a team to discuss response options. The CIRT also addresses each incident, unless it determines that an incident is sufficiently serious. In those instances, it notifies our Cyber Security Watch Team (“CSWAT”), which is responsible for addressing cybersecurity incidents that raise more significant risks.

Our CSWAT comprises senior IT, operations, risk, legal and compliance leaders across business segments. In addition to addressing our more significant cyber incidents, the CSWAT manages risks from matters related to business continuity, including risks posed by cybersecurity threats, and implements controls to mitigate such operational risks. Among other processes, this team reviews our programs and processes related to information security, third-party risk, vendor management, facilities, unplanned downtime, business disruption, business continuity and disaster recovery.

Cybersecurity Risk Board of Directors Oversight [Text Block]
As part of our overall risk management approach, we prioritize the identification and management of cybersecurity risk at several levels, including oversight by our Board of Directors, executive commitment, and employee training. Our Risk and Security Committee, comprising independent directors from our Board, assists the Board in overseeing our cybersecurity and data privacy risk. Specifically, our Risk and Security Committee, which meets quarterly, (i) receives periodic reports from our Chief Security Officer (“CSO”) on security programs, including incident reports, (ii) reviews cybersecurity risk assessments from information security, privacy, and internal audit management teams, including the adequacy and effectiveness of the Company’s internal controls regarding cybersecurity; (iii) reviews emerging cybersecurity developments and threats; (iv) reviews compliance with applicable laws and industry standards; and (v) periodically reviews our strategy to mitigate cybersecurity risks, such as our cyber insurance coverage and contingency plans in the event of security incidents or other system disruptions. At least quarterly, our Risk and Security Committee provides reports to the full Board of Directors regarding matters recently discussed by the Committee, which enables the full Board to provide additional oversight of our cyber risks and cyber processes. The full Board also reviews our cybersecurity risks in connection with its annual review of our enterprise risk mitigation programs.

Cybersecurity Risk Role of Management [Text Block]
Our cybersecurity organization includes a response team and management-level committees who support our processes to assess and manage cybersecurity risk as follows:

At the day-to-day operational level, we maintain an experienced information security team who are tasked with implementing our privacy and cybersecurity program and support the CSO in implementing our detection, reporting, security and mitigation functions. This team and the CSO work to develop and implement tools and processes designed to assist in identifying, containing and remediating cybersecurity incidents, and periodically retain consultants to assist with these activities. We generally seek to promote a company-wide awareness of cybersecurity risk through broad-based communications and educational initiatives, including regularly conducting phishing tests and holding employee trainings on our privacy, cybersecurity and information management policies, at least annually and more frequently when legal or other developments warrant.
The Technology, Security, and Privacy Council, co-chaired by the CSO, the Chief Information Officer (CIO), and the Chief Privacy Officer (CPO), leverages the combined expertise of various security, IT, legal, internal audit, and operational leaders across the company. This council provides a forum for these cross-functional members of management of our leadership team to consider emerging technologies, such as artificial intelligence and emerging cybersecurity risks; review cybersecurity and privacy regulations; review and update policies and standards as appropriate; and promote cross-functional collaboration to manage cybersecurity and privacy risks across the enterprise. Members of this council are responsible for reporting on cybersecurity and privacy risks to the Risk Oversight Committee (“ROC”).

The ROC, whose core members include our Chief Financial Officer, Chief Technology and Product Officer, Executive Vice President of Enterprise Operations, and Chief Legal Officer, oversees our company-wide risk mitigation strategies. With respect to cyber risks, the ROC's oversight function helps to ensure accountability, adequacy of resourcing, implementation of Company directives, and alignment of oversight provided by our Board of Directors and our senior leadership team. Some of the more significant risks discussed by the ROC are also reported to our Risk and Security Committee at least quarterly.

Background and Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated.

To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows:

income attributable to noncontrolling interests in other income (expense), net;

equity attributable to noncontrolling interests in common stock; and

cash flows attributable to noncontrolling interests in other, net financing activities.
Reclassification We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting for 2024 and 2023.
Operating Expenses
Operating Expenses

Our current definitions of operating expenses are as follows:

Cost of services and products (exclusive of depreciation and amortization): Expenses incurred in providing products and services to our customers. These expenses include:

employee-related expenses directly attributable to operating and maintaining our network (e.g., salaries, wages, benefits, and professional fees);

network and facilities expenses (e.g., third-party telecommunications expenses we incur for using other carriers' networks to provide services to our customers);

rents and utilities expenses;

equipment sales expenses (e.g., modem expenses); and

other expenses directly related to our operations.
Selling, general and administrative expenses: Corporate overhead and other operating expenses. These expenses include:

employee-related expenses directly attributable to selling products or services and employee-related expenses for administrative functions (e.g., salaries, wages, internal commissions, benefits and professional fees);

marketing and advertising;

property and other operating taxes and fees;

external commissions;

legal expenses associated with general matters;

bad debt expense; and

other selling, general, and administrative expenses.

These expense classifications may not be comparable to those of other companies.
Use of Estimates
Use of Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and require management to make estimates and assumptions that affect reported amounts of assets, liabilities, equity, revenue, expenses, and cash flows and related disclosures. These estimates are based on information available at the time, including historical and forward-looking factors, that we believe are reasonable; however, these estimates may differ materially from actual results.

We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 15 — Income Taxes and Note 17 — Commitments, Contingencies and Other Items for additional information.

For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third-party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.

For matters related to income taxes, if we determine the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. We do not recognize any portion of an uncertain tax position if the position has less than a 50% likelihood of being sustained. We recognize interest on the amount of unrecognized benefit from uncertain tax positions.
Assets Held for Sale
Assets Held for Sale

Assets and related liabilities are classified as held for sale when:

management commits to a plan to sell the assets;

the assets are available for immediate sale;

an active program to locate a buyer is initiated; and

the sale is probable within one year.
Assets and related liabilities held for sale are presented separately at the lower of (i) carrying amount or (ii) fair value less costs to sell. If the carrying amount exceeds fair value less cost to sell, a loss is recognized. Depreciation and amortization cease once assets are classified as held for sale. Assets classified as held for sale are remeasured each reporting period to ensure they are stated at the lower of (i) carrying amount or (ii) fair value less costs to sell.

Unless otherwise specified, the amounts and information presented in the notes do not include assets and liabilities that were classified as held for sale. See Note 2 — Divestitures for details on our recently completed divestitures.
Revenue Recognition
Revenue Recognition

We recognize revenue primarily from contracts with customers for communications and related services in accordance with Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" (“ASC 606”). Revenue is measured based on the consideration we expect to receive and is recognized when control of goods or services transfers to the customer. We also earn revenue from leasing arrangements (e.g., fiber capacity and conduit leases and colocation agreements) and governmental subsidies, which are outside the scope of ASC 606.

Under ASC 606, revenue is recognized using the following five-step model:

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when, or as, we satisfy a performance obligation.

Service and Equipment Revenue

We provide a broad range of communications services to business and residential customers — including global, enterprise, wholesale, government, and small and medium business customers. Certain contracts include equipment sales, which are not significant to our operations. We recognize revenue for services when we provide the applicable service or when control of a product is transferred.

For arrangements using third-party vendors, we assess whether we act as a principal or agent to determine whether revenue is reported on a gross or net basis.

Performance Obligations

Customer contracts are evaluated to determine whether the performance obligations are separable. If the performance obligations are deemed separable and separate earnings processes exist, the transaction price is allocated to each performance obligation based on its relative standalone selling price. The revenue associated with each performance obligation is then recognized as when, or as, the performance obligation is satisfied.

Deferred Revenue and Fees

Payments received in advance — such as design, planning, engineering, activation, or installation fees — are deferred unless they represent separate performance obligations. When these payments are not separate obligations, we recognize them over the contract term or estimated useful life, typically one to five years, based on historical experience. Termination fees or other charges negotiated with new contracts are also deferred and recognized over the new contract term.
Billing Practices

For access services, we generally bill fixed monthly charges one month in advance to customers and recognize revenue as service is provided over the contract term in alignment with the customer's receipt of service. For usage and other ancillary services, we generally bill in arrears and recognize revenue as usage or delivery occurs. In most cases, the amount invoiced for our service offerings constitutes the price that would be billed on a standalone basis.

Customer payments are made based on billing schedules included in our customer contracts, which is typically on a monthly basis.

Contract Costs

We defer (or capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 47 months for Mass Markets customers and 34 months for Business customers. These deferred costs are periodically monitored to reflect any significant change in assumptions.

Contract Modifications

In certain cases, customers may be permitted to modify their contracts. We evaluate the change in scope or price to identify whether the modification should be treated as a separate contract, as a termination of the existing contract and creation of a new contract, or as a change to the existing contract.

Indefeasible Rights of Use and Leases

We periodically sell transmission capacity on our network through indefeasible rights of use (“IRU”s), which grant the exclusive right to use a specified amount of capacity or fiber for a typical term of 20 years. Cash consideration received on transfers of transmission capacity is recognized as ASC 606 revenue, adjusted for time value of money and recognized ratably over the term. Cash consideration received on transfers of dark fiber is treated as non-ASC 606 lease revenue, which we also recognized ratably over the lease term. We treat contemporaneous exchanges of transmission capacity assets as non-revenue generating activities and therefore do not recognize revenue for these exchanges.

Service Level Commitments

We have service level commitments pursuant to contracts with certain of our customers. To the extent that we determine that such service levels were not achieved or may not have been achieved, we estimate the amount of credits to be issued and record a corresponding reduction to revenue in the period that the service level commitment was not met or may not be met.
Advertising Costs
Advertising Costs
Costs related to advertising are expensed as incurred and recorded as selling, general and administrative expenses in our consolidated statements of operations.
Legal Costs
Legal Costs

In the normal course of our business, we incur costs to hire and retain external legal counsel to advise us on finance, regulatory, litigation, and other matters. Subject to certain exceptions, we expense these costs as the related services are received.
Income Taxes
Income Taxes

We file a consolidated federal income tax return with our eligible subsidiaries. The provision for income taxes reflects taxes currently payable, tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to tax attributes carryforwards, including NOL carryforwards and tax credit carryforwards, and differences between the financial statement carrying value of assets and liabilities and the tax basis of those assets and liabilities. Deferred taxes are computed using enacted tax rates expected to apply in the year in which the differences are expected to affect taxable income. The effect on deferred income tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date.
We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain or adjust each valuation allowance on our deferred tax assets.
Cash and Cash Equivalents
Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments that are readily convertible into cash and are not subject to significant risk from fluctuations in interest rates. As a result, the value at which cash and cash equivalents are reported in our consolidated financial statements approximates their fair value. In evaluating investments for classification as cash equivalents, we require that individual securities have original maturities of ninety days or less and that individual investment funds have dollar-weighted average maturities of ninety days or less. To preserve capital and maintain liquidity, we invest with financial institutions we deem to be of sound financial condition and in high quality and relatively risk-free investment products. Our cash investment policy limits the concentration of investments with specific financial institutions or among certain products and includes criteria related to credit worthiness of any particular financial institution.

Book overdrafts occur when we have issued checks but they have not yet been presented to our controlled disbursement bank accounts for payment. Disbursement bank accounts allow us to delay funding of issued checks until the checks are presented for payment. Until the issued checks are presented for payment, the book overdrafts are included in accounts payable on our consolidated balance sheets. This activity is included in the operating activities section in our consolidated statements of cash flows.
Restricted Cash
Restricted Cash

Restricted cash consists primarily of cash and investments that collateralize our outstanding letters of credit and certain performance and operating obligations. Restricted cash is recorded as current or non-current assets in the consolidated balance sheets depending on the duration of the restriction and the purpose for which the restriction exists.
Accounts Receivable and Allowance for Credit Losses
Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recognized based upon the amount due from customers for the services provided or at cost for purchased and other receivables, less an allowance for credit losses. We use a loss rate method to estimate our allowance for credit losses. For more information on our methodology for estimating our allowance for credit losses, see Note 6 — Credit Losses on Financial Instruments.

We generally consider our accounts past due if they are outstanding over 30 days. Our past due accounts are written off against our allowance for credit losses and any recoveries are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable net of the allowance for credit losses approximates fair value. Accounts receivable balances acquired in a business combination are recorded at fair value for all balances receivable at the acquisition date and at the invoiced amount for those amounts invoiced after the acquisition date.
Property, Plant and Equipment
Property, Plant and Equipment

Purchased and constructed property, plant, and equipment are recorded at cost and assets acquired through business combinations are recorded at their estimated fair value as of the acquisition date. In both instances we include the estimated value of any associated legally or contractually required retirement obligations.

Expenditures for maintenance and repairs are expensed as incurred. Supplies used internally are carried at average cost, except for significant individual items which are carried at actual cost.

Depreciation Methods

Prior to January 1, 2024: Most assets were depreciated using the straight-line group method. Under this approach, assets with similar characteristics and useful lives were pooled together and depreciated over the group’s average remaining useful life. When assets were sold or retired in the normal course of business, their cost was removed from both the asset and accumulated depreciation accounts, with no gain or loss recognized.

Effective January 1, 2024: We re-established all of our assets individually, including accumulated depreciation, and transitioned to depreciating all assets individually using the straight-line method over each asset’s estimated useful life. When assets are sold in the normal course of business, a gain or loss is recognized in our consolidated statements of operations.

Leasehold Improvements and Capital Projects

Leasehold improvements are amortized over the shorter of the assets’ useful lives or the expected lease term. During the construction phase of network and other internal-use capital projects, we capitalize related employee and interest costs.

Useful Lives

We perform annual internal reviews to evaluate the reasonableness of the depreciable lives for our property, plant and equipment. Our reviews utilize models that take into account actual usage, physical wear and tear, replacement history, and assumptions about technology evolution. Our remaining useful life assessments evaluate the possible loss in service value of assets that may precede the physical retirement. Assets shared among many customers may lose service value as those customers reduce their use of the asset. However, the asset is not retired until all customers no longer utilize the asset and we determine there is no alternative use for the asset.

Impairment Testing

We review long-lived tangible assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. For assessment purposes, long-lived assets are grouped with other assets and liabilities at the lowest identifiable level for which we generate cash flows independently of other groups of assets and liabilities. An impairment loss is recognized only if the carrying amount of the asset group is not recoverable and exceeds its estimated fair value. Recoverability of the asset group to be held and used is assessed by comparing the carrying amount of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. If the asset group's carrying value is not recoverable, we recognize an impairment charge for the amount by which the carrying amount of the asset group exceeds its estimated fair value.
Asset Retirement Obligations

We recognize asset retirement obligations (“ARO”s) for the legally or contractually required removal of certain property, plant, and equipment from leased properties, as well as for the disposal of hazardous materials in owned facilities. When an ARO is identified — typically at the time an asset is acquired — we record the fair value of the obligation as a liability and capitalize a corresponding amount as part of the asset’s cost. Our fair value estimates were determined using the discounted cash flow method. In subsequent periods, we increase the ARO liability for the passage of time (accretion expense) and adjust the liability and related asset for changes in the timing or amount of expected future cash flows. The capitalized amount is then amortized over the asset’s estimated remaining useful life. If a removal obligation is not legally binding, we expense the related removal costs as incurred, rather than capitalizing them.
Goodwill and Intangible Assets
Goodwill and Intangible Assets

Intangible assets acquired in business combinations — including goodwill, customer relationships, capitalized software, trademarks, and trade names — are recorded at estimated fair value at the acquisition date. Other intangible assets not arising from business combinations are initially recorded at cost.

We are required to reassign goodwill to reporting units whenever reorganizations of our internal reporting structure change the composition of our reporting units. Goodwill is reassigned to the reporting units using a relative fair value approach. As our remaining goodwill was fully impaired or reclassified as held for sale as of December 31, 2025, no further reassignment is required as the goodwill balance has been reduced to zero. When the fair value of a reporting unit is available, we allocate goodwill based on the relative fair value of the reporting units. When fair value is not available, we utilize an alternative allocation methodology that we believe represents a reasonable approximation of the fair value of the operations being reorganized.

Amortization

Intangible assets without legal, regulatory, contractual, or other limiting factors are classified as indefinite-lived and are not amortized. For finite-lived intangible assets, we amortize using the straight-line method over the following estimated lives:

Customer relationships: 7 - 14 years, depending on customer type

Capitalized software: 3 - 7 years

Other intangible assets: 9 - 20 years

Internal Use Software

Internally used software, whether purchased or developed by us, is capitalized and amortized using the straight-line method over its estimated useful life. We capitalized costs of employees devoted to software development and external direct costs for materials and services. Costs are expensed until the project reaches the development stage. Subsequent additions, modifications, or upgrades are capitalized only if they add new functionality. Software maintenance, data conversion, and training costs are expensed as incurred. We review the remaining economic lives of our capitalized software annually. Capitalized software is included in other intangible assets, net, in our consolidated balance sheets.
Impairment Testing

Finite-lived intangible assets are evaluated for impairment when triggering events or changes in circumstances occur. If fair value is less than the carrying amount, we record an impairment charge for the difference.

We test goodwill for impairment annually as of October 31, or more frequently if events suggest a reporting unit’s fair value may fall below its carrying value. If the carrying value of a reporting unit exceeds its fair value of equity, we write-down goodwill. Because reporting units are not separate legal entities with full financial statements, we determine equity carrying value and future cash flows during each impairment assessment we perform on a reporting unit. This involves allocating assets, liabilities, and cash flows to reporting units using reasonable, consistent methodologies. This process requires significant estimates, judgments, and assumptions.
Pension and Post-Retirement Benefits
Pension and Post-Retirement Benefits
We recognize the funded status of our defined benefit and post-retirement plans as an asset or a liability on our consolidated balance sheets. Each year's actuarial gains or losses are a component of our other comprehensive income (loss), which is then included in our accumulated other comprehensive loss on our consolidated balance sheets. Pension and post-retirement benefit expenses are recognized over the period in which the employee renders service and becomes eligible to receive benefits. We make significant assumptions (including the discount rate, expected rate of return on plan assets, mortality and health care trend rates) in computing the pension and post-retirement benefits expense and obligations.
Foreign Currency
Foreign Currency

Local currencies of our foreign subsidiaries are the functional currencies for financial reporting purposes except for certain foreign subsidiaries. For operations with functional currencies other than the U.S. dollar, assets and liabilities are translated at period-end exchange rates, while revenue, expenses and cash flows use average monthly rates. Foreign currency translation gains and losses are recorded in accumulated other comprehensive loss in stockholders' (deficit) equity and in our consolidated statements of comprehensive (loss) income.

Before the November 1, 2023 sale of our EMEA business, many of our non-United States subsidiaries used the British pound or Euro as their functional currency, both of which fluctuated significantly against the U.S. dollar during the periods covered in this report when we operated the divested business. Prior to the divestiture, most investments in foreign subsidiaries were considered long-term. We continue to have immaterial operations transacted in foreign currencies. Foreign currency transaction gains and losses, including those not deemed long-term, are reported in other income (expense), net on our consolidated statements of operations.
For additional details on the sale of our EMEA business, see Note 2 — Divestitures.
Common Stock, Preferred Stock, Section 382 Rights Plan and Dividends
Common Stock

On December 18, 2024, we amended our articles of incorporation to eliminate the par value of our common stock (which was, prior to such amendment, $1.00 per share) as approved by our shareholders at our 2024 annual shareholders meeting. We recognized the change by reclassifying the balance in Additional paid-in capital to Common stock on our consolidated balance sheet as of December 18, 2024. All changes in capitalization previously recognized as Additional paid-in capital will hereinafter be recognized in Common stock. This change had no other impact on our consolidated financial statements.

As of December 31, 2025, we had 24 million shares authorized for future issuance under our equity incentive plans.
Preferred Stock

Holders of outstanding Lumen Technologies preferred stock are entitled to receive cumulative dividends, receive preferential distributions equal to $25 per share plus unpaid dividends upon Lumen's liquidation and vote as a single class with the holders of common stock.

Section 382 Rights Agreement

We maintain a Section 382 Rights Agreement to protect our U.S. federal net operating loss carryforwards ("NOLs") from certain Internal Revenue Code Section 382 limitations. Under the agreement, one preferred stock purchase right was distributed for each share of our outstanding common stock as of the close of business on February 25, 2019, and those rights currently trade in tandem with the common stock until they expire or detach under the agreement. This agreement was designed to deter trading that would result in a change of control (as defined in Internal Revenue Code Section 382), and therefore protect our ability to use our historical federal NOLs in the future. The agreement is scheduled to lapse in late 2026.

Dividends

The declaration and payment of dividends is at the discretion of our Board of Directors. We do not currently pay a dividend on our common stock.

On January 1, 2024, we adopted ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." This ASU clarifies that a contractual restriction on the sales of an investment in an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring its fair value. The adoption of this ASU did not have any impact on our consolidated financial statements.

Leases

On January 1, 2024, we adopted ASU 2023-01, “Leases (Topic 842): Common Control Arrangements.” This ASU requires all entities to amortize leasehold improvements associated with common control leases over the useful life to the common control group. The adoption of this ASU did not have any impact on our consolidated financial statements.
Income Taxes

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU requires that public business entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU became effective for us in the annual period of fiscal 2025. Refer to Note 15 — Income Taxes for more information.

Business Combinations

In August 2023, the FASB issued ASU 2023-05, “Business Combinations – Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement.” This ASU applies to the formation of entities that meet the definition of a joint venture (or a corporate joint venture).

The adoption of this ASU did not have a material impact on our consolidated financial statements.

Credit Losses

On January 1, 2023, we adopted ASU 2022-02, “Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures.” The ASU eliminates the TDR recognition and measurement guidance, enhances existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. The adoption of this ASU did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements

In December 2025, the Financial Accounting Standards Board ("FASB") issued ASU 2025-12 “Codification Improvements.” The ASU represents changes to the Codification that clarify, correct errors, or make minor improvements. The amendments make the Codification easier to understand and apply. The amendments in ASU 2025-12 are effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. Except for the amendments to Topic 260, "Earnings Per Share" this ASU can be applied either prospectively or retrospectively with transition method elected on an issue-by-issue basis. The Company is currently evaluating ASU 2025-12 to determine the impact it may have on our consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements."

In November 2025, the FASB issued ASU 2025-09, "Derivatives and Hedging (Topic 815): Hedge Accounting Improvements." This ASU introduces five targeted improvements to better align hedge accounting with entities’ risk management activities. The amendments in ASU 2025-09 are effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual reporting periods, with early adoption permitted and should be applied on a prospective basis for all hedging relationships. The Company intends to early adopt ASU 2025-09 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In November 2025, the FASB issued ASU 2025-08, "Financial Instruments — Credit Losses (Topic 326): Purchased Loans." This ASU requires that loans acquired without credit deterioration and deemed “seasoned” will be considered purchased seasoned loans and accounted for using the gross-up approach at acquisition (i.e., record the loan at its purchase price and separately record an allowance for expected credit losses). Seasoned loans include all loans acquired in a business combination, that do not have “more-than-insignificant” deterioration of credit quality since origination, as well as loans purchased at least 90 days after origination, where the purchaser was not involved in the origination of the loans. The amendments in ASU 2025-08 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early adoption permitted. This ASU should be applied prospectively to loans that are acquired on or after the initial application date. The Company intends to early adopt ASU 2025-08 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In September 2025, the FASB issued ASU 2025-07, "Derivatives and Hedging (Topic 815)" and "Revenue from Contracts with Customers (Topic 606)." The guidance refines the scope of Topic 815 to clarify which contracts are subject to derivative accounting. This ASU also provides clarification under Topic 606 for share-based payments from a customer in a revenue contract. The amendments in ASU 2025-07 are effective for fiscal years beginning after December 15, 2026, and interim reporting periods, with early adoption permitted. This ASU is permitted to be applied either prospectively to new contracts entered into on or after the date of adoption or on a modified retrospective basis through a cumulative-effect adjustment to the opening balance of retained earnings. The Company intends to early adopt ASU 2025-07 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, "Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software" which amends the guidance in ASC 350-40, "Intangibles — Goodwill and Other — Internal-Use Software." This ASU modernizes the recognition and disclosure framework for internal-use software costs, removing the previous “development stage” model and introducing a more judgment-based approach. The amendments in ASU 2025-06 are effective for fiscal years beginning after December 15, 2027, and for interim periods within those annual reporting periods, with early adoption permitted. This ASU is permitted to be applied prospectively, retrospectively or through a modified transition approach. The Company intends to early adopt ASU 2025-06 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05 "Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." This ASU provides entities with a practical expedient to simplify the estimation of expected credit losses on current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606 by allowing the assumption that current conditions as of the balance sheet date will not change during the remaining life of the asset. The amendments in ASU 2025-05 are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early prospective adoption permitted. The Company is currently evaluating ASU 2025-05 to determine the impact it may have on our consolidated financial statements.
In May 2025, the FASB issued ASU 2025-04 "Compensation - Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”)." This ASU clarifies the guidance on the accounting for share-based payment awards that are granted by an entity as consideration payable to its customer, with the intent to reduce diversity in practice and improve existing guidance by revising the definition of a “performance condition” and eliminating a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. It also clarifies the guidance in Topic 606 on the variable consideration constraint does not apply to share-based consideration payable to a customer “regardless of whether an award’s grant date has occurred”. ASU 2025-04 will be effective for the annual periods beginning after December 15, 2026 with early adoption permitted. The Company intends to early adopt ASU 2025-04 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In May 2025, the FASB issued ASU 2025-03 "Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity." This ASU revises current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity that meets the definition of a business. The amendments require an entity to consider the same factors that are currently required for determining which entity is the accounting acquirer in other acquisition transactions. The amendments in ASU 2025-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early prospective adoption permitted. The Company intends to early adopt ASU 2025-03 prospectively, effective January 1, 2026. The adoption is not expected to have an impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, "Debt — Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments." This ASU clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. The amendments in ASU 2024-04 are effective for the annual period of fiscal 2026, and early adoption is permitted. This ASU is permitted to be applied on either a prospective or retrospective basis. As of December 31, 2025, we do not hold convertible debt instruments and do not expect this ASU will have any impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses." This ASU requires additional footnote disclosure of the details of certain income statement expense line items as well as additional disclosure about selling expenses. The amendments in ASU 2024-03 are effective for the annual period of fiscal 2027, and early adoption is permitted. The guidance is to be applied prospectively, with the option for retrospective application. The Company is currently evaluating ASU 2024-03 and the impact the adoption of this standard will have on our disclosures.
Credit Losses on Financial Instruments
To assess our expected credit losses on financial instruments, we aggregate financial assets with similar risk characteristics to monitor their credit quality or deterioration over the life of such assets. We periodically monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change. We separately evaluate financial assets that do not share risk characteristics with other financial assets. Our financial assets measured at amortized cost primarily consist of accounts receivable.
We use a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our review of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable.

If there is an unexpected deterioration of a customer's financial condition or an unexpected change in economic conditions, including macroeconomic events, we assess the need to adjust the allowance for credit losses. Any such resulting adjustments would affect earnings in the period that adjustments are made.

The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding our allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future, and we may use methodologies that differ from those used by other companies.
