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 or press releases by us and our management may include, forward-looking statements about our business, financial condition, operating results, or prospects. These "forward-looking" statements are defined by, and are subject to the "safe harbor" protections under the federal securities laws. 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 our agreement to sell our Mass Markets fiber-to-the-home business in 11 states to AT&T, investments, product development, Private Connectivity FabricSM and Quantum Fiber 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 position, 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 effects of intense competition from a wide variety of competitive providers, including decreased demand for our more mature service offerings and increased pricing pressures;

the effects of new, emerging, or competing technologies, including those that could make our products less desirable or obsolete;

our ability to successfully and timely attain our key operating imperatives, including simplifying and consolidating our network, simplifying and automating our service support systems, attaining our Quantum Fiber buildout schedule, replacing aging or obsolete plant and equipment, strengthening our relationships with customers, and attaining projected cost savings;

our ability to successfully and timely monetize our network-related assets through leases, commercial service arrangements or similar transactions (including as part of our Private Connectivity FabricSM solutions), including the possibility that the benefits of or demand for these transactions may be less than anticipated, that the costs thereof may be more than anticipated, or that we may be unable to satisfy any conditions of any such transactions in a timely manner, or at all;

our ability to enhance our growth products and manage the decline of our legacy products, including by maintaining the quality and profitability of our existing offerings, introducing profitable new offerings on a timely and cost-effective basis, and transitioning customers from our legacy products to our newer offerings;

our ability to successfully and timely implement our corporate strategies, including our transformation, modernization and simplification, buildout and deleveraging strategies;

our ability to successfully consummate and timely realize the anticipated benefits from the pending sale of our Mass Markets fiber-to-the-home business in 11 states to AT&T;

changes in our operating plans, corporate strategies, or capital allocation plans, whether based upon changes in our cash flows, cash requirements, financial performance, financial position, market or regulatory conditions, or otherwise;

the impact of any future material acquisitions or divestitures that we may transact, including our pending divestiture of our Mass Markets fiber-to-the-home business in 11 states;

the negative impact of increases in the costs of our pension, healthcare, post-employment, or other benefits, including those caused by changes in capital markets, interest rates, mortality rates, demographics, or regulations;

the impact of events that harm our reputation or brands, including the potential negative impact of customer or shareholder complaints, government investigations, security breaches, or service outages impacting us or our industry;

the effects of changes in interest rates or inflation;

the effects of more general factors such as changes in exchange rates, in operating costs, in public policy, in the views of financial analysts, or in general market, labor, economic, public health, or geopolitical conditions; and

other risks referenced in the "Risk Factors" section or other portions of this report or other of our filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2024.

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. Given these uncertainties, investors are cautioned not to unduly rely upon our forward-looking statements, which speak only as of the date made. We undertake no obligation to publicly update or revise any forward-looking statements for any reason, whether as a result of new information, future events or developments, changed circumstances, or otherwise. Furthermore, any information about our intentions contained in any of our forward-looking statements reflects our intentions as of the date of such forward-looking statement, and is based upon, among other things, our assessment of regulatory, technological, industry, competitive, economic, and market conditions as of such date. We may change our intentions, strategies or plans (including our capital allocation plans) at any time and without notice, based upon any changes in such factors or otherwise.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

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

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 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

Our consolidated balance sheet as of December 31, 2024, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe these consolidated financial statements include all normal recurring adjustments necessary to fairly state the results for the interim periods. The consolidated results of operations and cash flows for the first six months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024.

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: (i) income attributable to noncontrolling interests in other income, net, (ii) equity attributable to noncontrolling interests in additional paid-in capital, and (iii) cash flows from transactions attributable to noncontrolling interests in other, net financing activities.

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. See Note 4—Revenue Recognition and Note 11—Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses or net (loss) income for any period.

Summary of Significant Accounting Policies

Refer to the significant accounting policies described in Note 1— Background and Summary of Significant Accounting Policies to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024, as further supplemented below:

Assets Held for Sale

We classify assets and related liabilities as held for sale when: (i) management has committed to a plan to sell the assets; (ii) the net assets are available for immediate sale; (iii) there is an active program to locate a buyer; and (iv) the sale and transfer of the net assets is probable within one year. Assets and liabilities held for sale are presented separately on our consolidated balance sheets with a valuation allowance, if necessary, to recognize the net carrying amount at the lower of carrying value or fair value, less costs to sell. Depreciation of property, plant and equipment and amortization of finite-lived intangible assets and right-of-use assets are not recorded while these assets are classified as held for sale. For each reporting period that assets are classified as being held for sale, they are tested for recoverability. Unless otherwise specified, the amounts and information presented in the accompanying notes do not include assets and liabilities that have been reclassified as held for sale as of June 30, 2025. See Note 2 for information about our agreement to sell our Mass Markets fiber-to-the-home business in 11 states to AT&T and our classification of this business as held for sale on May 21, 2025.

Recently Adopted Accounting Pronouncements

Segments

We adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” for the year ended December 31, 2024. 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 11—Segment Information for more information on our segment reporting.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (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. This standard is effective for the annual period of fiscal 2026 and early adoption is permitted. As of June 30, 2025, we did not have any outstanding 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. This standard is effective for the annual period of fiscal 2027 and early adoption is permitted. The guidance will be applied prospectively, with the option for retrospective application. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

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 their 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 five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU will become effective for us for the annual reporting period ending December 31, 2025. The Income Taxes footnote to the consolidated financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2025 will align with the standard. We do not anticipate this standard will affect our operating results.

Note 2—Planned Divestiture of the 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 to AT&T for a pre-tax total of $5.75 billion in cash, subject to working capital and various other 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 we experience delays in completing the transaction or if there are changes in other assumptions that impact our estimates.

We do not believe this divestiture transaction represents a strategic shift for Lumen and therefore, does not meet the criteria to be classified as a discontinued operation. As a result, we will continue to report our operating results for the Mass Markets fiber-to-the-home business (the "disposal group") in our consolidated operating results until the transaction is closed. We anticipate closing this divestiture in the first half of 2026, upon receipt of all requisite regulatory approvals, as well as the satisfaction of other customary conditions.

As of June 30, 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 $22 million of depreciation for the three and six months ended June 30, 2025, if the disposal group did not meet the held for sale criteria.

Under the terms of the purchase agreement, Lumen agreed to grant the purchaser an indefeasible right to use (“IRU”) certain Lumen retained fiber assets following the close 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 June 30, 2025 are as follows:

(1)     As of June 30, 2025, this amount excluded goodwill classified as held for sale of approximately $1.3 billion. See Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business.
(2)    Certain customer relationships with a gross carrying value of $161 million and capitalized software with a gross carrying value of $211 million became fully amortized during 2024 and were retired during the first quarter of 2025.

As of June 30, 2025 and December 31, 2024, the gross carrying amount of goodwill, customer relationships, indefinite-lived, and other intangible assets was $13.1 billion and $15.4 billion, respectively.

Our goodwill was derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired. We report our results within two segments: Business and Mass Markets. See Note 11—Segment Information for more information on these segments.

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. 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 is October 31, at which date we assess our reporting units.

On May 21, 2025 (the date we agreed to sell the disposal group), we had three reporting units: (i) Mass Markets, (ii) North American Business ("NA Business"), and (iii) Asia Pacific region ("APAC"). 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.

We determined that the classification of the Mass Markets fiber-to-the-home business as held for sale as described in Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business 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 a non-cash, non-tax-deductible goodwill impairment charge of $628 million for the three and six months 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 impairments.

The following table shows the rollforward of goodwill assigned to our reportable segments from December 31, 2024 to June 30, 2025.

Operating Lease Revenue

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 income are included in Operating revenue in the consolidated statements of operations.

For the three months ended June 30, 2025 and 2024, our gross rental revenue was $265 million and $240 million, respectively, which represented approximately 9% and 7%, respectively, of our operating revenue for the three months ended June 30, 2025 and 2024. For the six months ended June 30, 2025 and 2024, our gross rental revenue was $527 million and $461 million, respectively, which represented approximately 8% and 7%, respectively, of our operating revenue for the six months ended June 30, 2025 and 2024.

Customer Receivables and Contract Balances

(2)     As of June 30, 2025, this amount excluded $30 million of contract liabilities associated with the disposal group reclassified 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 three and six months ended June 30, 2025, we recognized $71 million and $365 million, respectively, of revenue that was included in contract liabilities of $733 million as of January 1, 2025, including contract liabilities that were classified as held for sale. During the three and six months ended June 30, 2024, we recognized $43 million and $343 million of revenue that was included in contract liabilities of $698 million as of January 1, 2024.

Performance Obligations

As of June 30, 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 June 30, 2025, the transaction price related to unsatisfied performance obligations that are expected to be recognized for the remainder of 2025, 2026, and thereafter was $1.6 billion, $2.1 billion and $2.3 billion, respectively.

These amounts exclude (i) the value of unsatisfied performance obligations for contracts for which we recognize revenue in amounts for 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), (ii) contracts that are classified as leasing arrangements or government assistance that are not subject to ASC 606, and (iii) the value of unsatisfied performance obligations for contracts which relate to the disposal group classified as held for sale.

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 on our consolidated balance sheets. We include the amount of deferred costs expected to be amortized beyond the next 12 months in Other liabilities on our consolidated balance sheets. We assess deferred acquisition and fulfillment costs for impairment on a quarterly basis.

First Lien Note Refinancing

On June 30, 2025, Level 3 Financing, Inc. issued $2.0 billion of 6.875% First Lien Notes due 2033. On such date, Level 3 Financing used the net proceeds from the offering, together with cash on hand, to redeem (i) all $925 million aggregate principal amount of Level 3 Financing's then-outstanding first lien 10.500% Senior Secured Notes due 2030, (ii) all $668 million aggregate principal amount of Level 3 Financing’s then-outstanding 10.500% First Lien Notes due 2029, and (iii) $167 million aggregate principal amount of Level 3 Financing’s outstanding 11.000% First Lien Notes due 2029, in each case including the payment of redemption premium and accrued interest, as well as related fees and expenses (collectively, the "First Lien Note Refinancing").

The Company determined that the First Lien Note Refinancing constituted a debt extinguishment and recorded a loss of $236 million, which is included in our aggregate Net (loss) gain on early retirement of debt in Other (expense) income, net in our consolidated statement of operations for the three and six months ended June 30, 2025.

Credit Facilities Refinancing

On March 27, 2025, Level 3 Financing (i) refinanced all of the outstanding secured Term Loan B-1 facilities and secured Term Loan B-2 facilities under its existing Credit Agreement, dated March 22, 2024 (the "2024 Level 3 Credit Agreement"), by and among Level 3 Financing, as borrower, Level 3 Parent, as guarantor, Wilmington Trust, National Association, as administrative agent and collateral agent, and the lenders from time to time party thereto and (ii) entered into an amendment to the 2024 Level 3 Credit Agreement (collectively, the "Credit Facilities Transactions"). This amendment revised the 2024 Level 3 Credit Agreement to, among other things, (i) reduce the pricing on Level 3 Financing’s term loan facility and make related changes to effect such repricing and (ii) extend the maturity of Level 3 Financing's term loan facility to 2032. Immediately following the Credit Facilities Transactions, Level 3 Financing had $2.4 billion of outstanding borrowings under its new secured Term Loan B-3 facility.

The Company determined that the Credit Facilities Transactions constituted a debt extinguishment and recorded a loss of $35 million, which is included in our aggregate Net (loss) gain on early retirement of debt in Other (expense) income, net in our consolidated statement of operations for the six months ended June 30, 2025.

2024 Debt Transactions

For information on various issuances, exchanges, or payments of long-term indebtedness by Lumen or its subsidiaries during 2024, see Note 7—Long-Term Debt and Credit Facilities in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024.

Lumen Credit Agreements

Lumen is a party to (i) a Superpriority Revolving/Term A Credit Agreement, dated March 22, 2024, providing for superpriority series A and series B Revolving Credit Facilities (respectively, the “Series A Revolving Credit Facility” and “Series B Revolving Credit Facility,” and, together, the “Revolving Credit Facilities”) and a superpriority secured term loan facility (the “Lumen TLA”), (ii) a Superpriority Term B Credit Agreement, dated March 22, 2024, providing for two superpriority secured term loan facilities, maturing in 2029 and 2030, respectively (together, the “Lumen TLB”), and (iii) a credit agreement providing for Lumen's Term Loan B maturing in 2027, all of which are described in further detail in Note 7—Long-Term Debt and Credit Facilities— in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024.

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.

24


Table of Contents
Both of the 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.

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.

As of June 30, 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.

Level 3 Financing Credit Agreement

As of June 30, 2025, Level 3 Financing had $2.4 billion of non-amortizing secured Term Loan B-3 outstanding under the term loan facility established by the 2024 Level 3 Credit Agreement (as amended through March 27, 2025, the "Level 3 Credit Agreement").

Borrowings under the term loan 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 facility will be 4.25%. The term loan facility is subject to a SOFR floor of 0.50%.

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 September 27, 2025). 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.

Senior Notes of Lumen and its Subsidiaries

The Company’s consolidated indebtedness at June 30, 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 primarily under (i) an uncommitted $225 million revolving letter of credit facility and (ii) the Revolving Credit Facilities.

At June 30, 2025, we had $234 million undrawn letters of credit outstanding, (i) $231 million of which were issued under the Revolving Credit Facilities and (ii) $3 million of which were issued under a separate facility maintained by other 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 will be 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 lien notes are secured by a first priority 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:

(i) 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 stepping down to 5.25 to 1.00 with respect to each fiscal quarter ending after December 31, 2025; or

(ii) 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 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 Companies

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 June 30, 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.

Table of Contents
Guarantees

Lumen does not guarantee the debt of any unaffiliated parties, but, as noted above, as of June 30, 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.

As of June 30, 2025, we classified certain property, plant and equipment, net as held for sale and discontinued recording depreciation on the disposal group. See Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business.

We recorded depreciation expense of $440 million and $901 million for the three and six months ended June 30, 2025 and $466 million and $942 million for the three and six months ended June 30, 2024, respectively.

Note 7—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.

Table of Contents
Service costs for our pension and post-retirement benefit plans are included in the Cost of services and products (exclusive of depreciation and amortization) and Selling, general and administrative line items on our consolidated statements of operations and all other costs listed above are included in Other income, net on our consolidated statements of operations for the three and six months ended June 30, 2025 and 2024. As a result of ongoing efforts to reduce our workforce, we recognized a one-time charge of $2 million during the three months ended June 30, 2024 for special termination benefit enhancements paid to certain eligible employees upon voluntary retirement.

Our Combined 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. The amount of any future non-cash settlement charges will be dependent on several factors, including the total amount of our future lump sum benefit payments.

Benefits paid by the Combined Pension Plan are paid through a trust that holds the Plan's assets. The amount of required contributions to the Combined Pension Plan in 2025 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 expect to be required to make any additional contributions in 2025.

For the three months ended June 30, 2024, we excluded from the calculation of diluted loss per share less than 1 million shares potentially issuable under incentive compensation plans or convertible securities, as their effect, if included, would have been anti-dilutive due to our net loss position.

Our calculation of diluted (loss) earnings per common share excludes non-vested restricted stock awards that are anti-dilutive based upon the terms of the award. Such shares were 22.9 million and 24.1 million for the three months ended June 30, 2025 and 2024, respectively and 18.2 million and 22.2 million for the six months ended June 30, 2025 and 2024, respectively.

Note 10—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), interest rate swap contracts, 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.

31


Table of Contents
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 following table presents the carrying amounts and estimated fair values of our financial assets and liabilities as of June 30, 2025 and December 31, 2024:

Note 11—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.

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 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 the three and six months ended June 30, 2025 and 2024, based on the segment categorization under which we were operating at June 30, 2025.

Table of Contents
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 include 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.

The following table reconciles total segment adjusted EBITDA to net (loss) income for the three and six months ended June 30, 2025 and 2024:

Note 12—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, at June 30, 2025 and December 31, 2024, we had accrued $76 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 in our consolidated balance sheets as of such dates. We cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $76 million accrual at June 30, 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.

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.

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.

Latin American Tax Litigation and 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. 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 10—Fair Value of Financial Instruments.

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 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. Preliminary estimates of potential damage claims against all defendants exceed $2 billion. A trial to determine liability only has been set for September 2025.

911 Surcharge

In June 2021, the Company was served with a complaint filed in the Santa Fe County District Court by Phone Recovery Services, LLC, acting on behalf of the State of New Mexico. The complaint claims Qwest Corporation and CenturyTel of the Southwest have violated the New Mexico Fraud Against Taxpayers Act since 2004 by failing to bill, collect, and remit certain 911 surcharges from customers. Through pre-trial proceedings, the Court narrowed the issues to be resolved by jury. On August 21, 2024, a jury decided the remaining issues, and consequently all claims asserted, in Lumen's favor. The parties filed and then withdrew appeals.

Minnesota State Income Tax Audit

On May 12, 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 income tax year. The Company intends to file a timely notice of appeal of the Order with the Minnesota Tax Court in the third quarter of 2025.

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.
38


Table of Contents

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 12 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. For additional information on our contingencies, see Note 18—Commitments, Contingencies and Other Items to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024. 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.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

All references to "Notes" in this Item 2 of Part I refer to the Notes to Consolidated Financial Statements included in Item 1 of Part I of this report. Certain statements in this report constitute forward-looking statements. See "Special Note Regarding Forward-Looking Statements" immediately prior to Item 1 of Part I of this report for factors relating to these statements and "Risk Factors" in Item 1A of Part II of this report and in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024 or other of our filings with the SEC for a discussion of certain risk factors applicable to our business, financial condition, results of operations, liquidity, or prospects.

Overview

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") included herein should be read in conjunction with the information included in our Annual Report on Form 10-K for the year ended December 31, 2024 and with the consolidated financial statements and related notes in Item 1 of Part I of this report. The results of operations and cash flows for the first six months of the year are not necessarily indicative of the results of operations and cash flows that might be expected for the entire year.

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. We are among the largest providers of communications services to domestic and global enterprise customers. Our long-haul network throughout North America and Asia Pacific connects to metropolitan fiber networks that we operate. As of June 30, 2025, we had approximately 24,000 employees.

Planned Divestiture of the 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 (including approximately 95% of Quantum Fiber) in 11 states to AT&T for a pre-tax total of $5.75 billion in cash, subject to working capital and other various purchase price adjustments. We expect to close this transaction in the first half of 2026, although we can provide no assurance to this effect. The actual amount of our net after-tax proceeds from this divestiture could vary from the amounts we currently estimate. The sales of fiber assets to AT&T will not result in Lumen fully exiting its fiber business in any state. For additional information, see Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business.

Macroeconomic Changes

Over the past few years, macroeconomic changes have impacted us and our customers in several ways.

We believe macroeconomic changes over the past few years have resulted in (i) increases in certain revenue streams and decreases in others, (ii) operational challenges resulting from inflation and shortages of certain components and other supplies that we use in our business, (iii) delays in our cost transformation initiatives, and (iv) delayed decision-making by certain of our customers. None of these effects, individually or in the aggregate, have to date materially impacted our financial performance or financial position.

Industry developments over the past few years have increased fiber construction demand from customers. The resulting increase in construction labor rates increased the cost of enabling units to be capable of receiving our Quantum Fiber broadband services. We believe these factors also occasionally contributed to a delay in attaining our Quantum Fiber buildout targets.

42


Table of Contents
Increasing business and geopolitical uncertainty, new tariffs, supply constraints, or inflationary pressures could materially impact our financial results in a variety of ways, including by increasing our expenses, decreasing our revenues, further delaying our network expansion plans, further delaying customer decision-making, or otherwise interfering with our ability to deliver products and services.

To the extent these above-mentioned macroeconomic pressures continue, we could experience additional deterioration in our projected cash flows or market capitalization.

Reporting Segments

Our reporting segments are currently organized by customer focus, as follows:

Business Segment: Under our Business segment, we provide our products and services under the following five sales channels:

Large Enterprise: Under our large enterprise sales channel, we provide our products and services to large enterprise customers and carriers in North America.

Mid-Market Enterprise: Under our mid-market enterprise sales channel, we provide our products and services directly to medium-sized enterprises in North America, as well as through our indirect channel partners.

Public Sector: Under our public sector sales channel, we provide our products and services to the public sector, including the U.S. Federal government, state and local governments and research and education institutions.

Wholesale: Under our wholesale sales channel, we provide our products and services to a wide range of other communication companies providing wireline, wireless, cable, voice and data center services.

International and Other: Under our international and other sales channel, we provide (i) various products and services to multinational and global enterprise customers and carriers and (ii) services under the limited number of our remaining content delivery network ("CDN") contracts.

Mass Markets Segment: Under our Mass Markets segment, we provide products and services to domestic residential and small business customers. At June 30, 2025, we served 2.5 million broadband subscribers under our Mass Markets segment.

See Note 11—Segment Information to our consolidated financial statements in Item 1 of Part I of this report for additional information.

We categorize our Business segment revenue among the following products and services categories:

Grow, which includes existing and emerging products and services in which we are significantly investing, including our dark fiber and conduit, Edge Cloud, IP, managed security, software-defined wide area networks, Unified Communications and Collaboration, and wavelengths services;

Nurture, which includes our more mature offerings, including ethernet, and VPN data networks services;

Harvest, which includes our legacy services managed for cash flow, including Time Division Multiplexing voice and private line services; and

Other, which includes equipment sales, managed and professional service solutions, and other services.

We categorize our Mass Markets products and services revenue among the following categories:

Fiber Broadband, under which we provide high speed broadband services to residential and small business customers utilizing our fiber-based network infrastructure;
43


Table of Contents

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.

Trends Impacting Our Operations

In addition to the above-described impact of macroeconomic and industry pressures, our consolidated operations have been, and will continue to be, impacted by the following trends:

Customers’ demand for automated products and services and competitive pressures will require that we continue to invest in new technologies and automated processes to improve our customers' experience and reduce our operating expenses.

The increased use of multi-cloud storage, digital applications, video streaming, gaming, robotics, quantum computing, and artificial intelligence has substantially increased demand for robust, scalable network services. We are continuing to enhance our product and service offerings and taking other steps to enable customers to have access to greater bandwidth and capacity.

Businesses continue to adopt distributed, global operating models. We are expanding and enhancing our fiber network, connecting more buildings to our network to generate revenue opportunities and reducing our reliance upon other carriers.

Changes in customer preferences and in the regulatory, technological, and competitive environment are (i) significantly reducing demand for our more mature service offerings, commoditizing certain offerings, or resulting in volume or rate reductions for other offerings and (ii) creating certain opportunities for us arising out of increased demand for advanced networking services and high-speed, low-latency secure data transmissions.

The operating margins of some of our newer, more technologically advanced services, some of which may connect to customers through other carriers, are lower than the operating margins on our traditional, on-net wireline services.

Uncertainties regarding our financial performance and overall leverage have caused, and may continue to cause, certain customers and other third parties to avoid transacting business with us.

Our expenses will be impacted by higher vendor costs, reduced economies of scale, and other dis-synergies due to our 2022 and 2023 divestitures, our pending divestiture (upon its completion), and any future divestitures.

Declines in our traditional wireline services and other more mature offerings have necessitated continuous right-sizing of our cost structure to remain competitive.

We have historically generated revenue by entering into transactions that utilize excess conduit, fiber, or other assets on our network to create custom networks for our customers, including through our Private Connectivity FabricSM solutions. We plan to continue to actively pursue additional revenue-generating opportunities with respect to these assets through right-of-use agreements, leases, or other agreements. We may or may not consummate such transactions from time to time, and the revenue from, and obligations associated with, any such opportunities may be significant, either individually or in the aggregate. The completion of any future transactions may be subject to customary conditions, and may not be executed in a timely manner, or at all.

These and other developments and trends impacting our operations are discussed elsewhere in this Item 2.

Cost of Services and Products (exclusive of depreciation and amortization)

Cost of services and products (exclusive of depreciation and amortization) decreased by $29 million and increased by $6 million for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. For the three months ended June 30, 2025 compared to the three months ended June 30, 2024, the decrease was primarily due to a decrease of $48 million related to equipment and maintenance expense, partially offset by an increase of $26 million in employee-related expense. For the six months ended June 30, 2025 compared to the six months ended June 30, 2024, the increase was primarily due to an increase of $68 million in network expenses, partially offset by a decrease of $54 million related to equipment and maintenance expense and a decrease of $13 million in employee-related expense from lower headcount.

Selling, General and Administrative

Selling, general and administrative expenses increased by $13 million and decreased by $135 million for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. For the three months ended June 30, 2025 compared to the three months ended June 30, 2024, the increase was primarily due to (i) an increase of $49 million due to fees related to the relinquishment of our funding received under the FCC's Rural Digital Opportunity Fund (“RDOF”), (ii) an increase of $16 million related to a loss on the sale of operating assets in the second quarter of 2025, and (iii) an increase of $9 million related to property and other taxes. These increases were partially offset by a decrease of $51 million in employee-related expenses from lower headcount. For the six months ended June 30, 2025 compared to the six months ended June 30, 2024, the decrease was primarily due to a decline of (i) $140 million in legal and other professional fees, mainly driven by our debt transaction in the first quarter of 2024 with no comparably-sized transaction in the first quarter of 2025, and (ii) $83 million in employee-related expenses from lower headcount. These decreases were partially offset by (i) an increase of $65 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 and (ii) an increase of $49 million due to fees related to the relinquishment of our funding received under the FCC's RDOF.

Net (Gain) Loss on Sale of Business

For a discussion of the net (gain) loss on sale of business that we recognized for the three and six months ended June 30, 2024, see Note 2—Divestitures of the Latin American, ILEC and EMEA Businesses to our consolidated financial statements in Item 8 of Part II of our Annual Report Form 10-K for the year ended December 31, 2024.

Depreciation and Amortization

Amortization248 277 (10)%500 549 (9)%
Total depreciation and amortization$688 743 (7)%1,401 1,491 (6)%

Depreciation expense decreased by $26 million and $41 million for the three and six months ended June 30, 2025, respectively, as compared to the three and six months ended June 30, 2024. These decreases were primarily due to (i) a decrease of $7 million and $19 million, respectively, from accelerated depreciation of CDN assets in 2024, (ii) a decrease of $22 million for the three and six months ended June 30, 2025, respectively, as compared to the three and six months ended June 30, 2024, due to the discontinuation during the second quarter of 2025 of the depreciation of the tangible assets of our Mass Markets fiber-to-the-home business held for sale, and (iii) a decrease of $8 million for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, due to decommissioned assets. These decreases were partially offset by an increase of $6 million and $9 million, respectively, associated with the net increase in depreciable assets.

Table of Contents

Amortization expense decreased by $29 million and $49 million for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. This was due to a $9 million and $22 million decrease, respectively, associated with net reduction in amortizable assets and a $19 million and $26 million decrease, respectively, associated with the accelerated amortization of software assets.

Further analysis of our segment operating expenses by segment is provided below in "Segment Results."

Goodwill Impairment

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 disposal group as held for sale related to the divestiture of our Mass Markets fiber-to-the-home business as described in Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business was considered an event or change in circumstance which required an assessment of our goodwill for impairment as of April 30, 2025.

We report under two segments: Business and Mass Markets. 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 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.

See Note 3—Goodwill, Customer Relationships and Other Intangible Assets to our consolidated financial statements in Item 1 of Part I of this report for further details.

Interest Expense

Interest expense decreased by $35 million and increased by $21 million for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. The decrease for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, was due to the decrease in the average interest rate from 7.74% to 7.31% and a decrease of approximately $1 billion in average outstanding long-term debt for the period. The increase for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, was due to the increase in the average interest rate from 6.99% to 7.49% for the period. This increase was partially offset by a decrease of approximately $1 billion in average outstanding long-term debt for the period.

Adjusted EBITDA is a non-GAAP financial measure and excludes (i) income tax (benefit) expense, (ii) other expense, net, which is inclusive of the net (loss) gain on extinguishment and modification of debt, interest income, and interest expense, (iii) depreciation and amortization expense, (iv) goodwill impairments and (v) non-cash stock compensation. We believe Adjusted EBITDA is a relevant and useful metric to provide to investors, is an important part of our internal reporting and is a key non-GAAP measure used by management to evaluate profitability and operating performance of Lumen and to make resource allocation decisions. There are material limitations to using Adjusted EBITDA as a financial measure, including the difficulty associated with comparing companies that use similar performance measures whose calculations may differ from our calculations. Additionally, by excluding the above-listed items, Adjusted EBITDA may exclude items that investors believe are important components of our performance. Adjusted EBITDA should not be considered a substitute for other measures of financial performance reported in accordance with GAAP.

Three and six months ended June 30, 2025 compared to the three and six months ended June 30, 2024

Business segment revenue decreased $88 million and $155 million, respectively, for the three and six months ended June 30, 2025, as compared to the comparable periods ended June 30, 2024. Within each product category for the three and six months ended June 30, 2025 as compared to the comparable periods ended June 30, 2024:

Grow increased by $64 million and $141 million, respectively, primarily due to an increase of revenue from dark fiber and conduit of $37 million and $88 million and growth in IP services of $17 million and $36 million, respectively;

Nurture decreased by $116 million and $226 million, respectively, primarily due to declines in traditional VPN services of $91 million and $179 million and declines in Ethernet services of $26 million and $52 million, respectively;

Harvest decreased by $14 million and $62 million, respectively, primarily due to a $38 million and $81 million decline in legacy voice services and a $17 million and $29 million decline in other legacy products and services, respectively, partially offset by an increase in private line revenue of $43 million and $58 million attributable primarily to temporary rate increases; and

Other decreased by $22 million and $8 million, respectively, primarily due to decreases in equipment sales revenue of approximately $18 million and $8 million, respectively.

Business segment expense decreased by $76 million and $141 million for the three and six months ended June 30, 2025, respectively, as compared to the three and six months ended June 30, 2024, primarily driven by a decrease of $11 million and $68 million, respectively, in employee-related costs due to lower headcount and $70 million in overall network expense for both the three and six months ended June 30, 2025.

Business segment adjusted EBITDA as a percentage of segment revenue was 46% for both the three and six months ended June 30, 2025 and 45% for both the three and six months ended June 30, 2024.

Mass Markets segment revenue decreased $88 million and $129 million for the three and six months ended June 30, 2025, respectively, as compared to the three and six months ended June 30, 2024. More specifically, within each product category:

Fiber Broadband revenue increased $36 million and $75 million, respectively, primarily driven by growth in the number of fiber customers associated with our continued increase in enabled locations from our Quantum Fiber buildout;

Other Broadband revenue decreased $53 million and $111 million, respectively, primarily due to fewer customers for our lower speed copper-based broadband services; and

Voice and Other decreased $71 million and $93 million, respectively, principally due to the continued loss of copper-based voice customers and a decrease of $46 million due to the relinquishment of our funding received under the FCC's RDOF. See the "Liquidity and Capital Resources—Federal Broadband Support Programs" in Item 2 of Part I below for more information.

Mass Markets segment expense decreased $29 million and $68 million for the three and six months ended June 30, 2025, respectively, as compared to the three and six months ended June 30, 2024, primarily driven by decreases of (i) $12 million and $30 million, respectively, in employee-related costs due to lower headcount, (ii) $6 million and $11 million, respectively, in marketing and advertising expense, (iii) $4 million and $6 million, respectively, in professional fees, and (iv) $6 million and $11 million, respectively, in overall network expense.

Liquidity and Capital Resources

Overview of Sources and Uses of Cash

We are a holding company that is dependent on the capital resources of our subsidiaries to satisfy our parent company liquidity requirements. Several of our significant operating subsidiaries have borrowed funds either on a standalone basis or as part of a separate restricted group with certain of its subsidiaries or affiliates. The terms of the instruments governing the indebtedness of these borrowers or borrowing groups may restrict our ability to access their accumulated cash. In addition, our ability to access the liquidity of these and other subsidiaries may be constrained by tax, legal, and other limitations. For additional information, see "Debt Instruments and Financing Arrangements" below.

At June 30, 2025, we held cash and cash equivalents of $1.6 billion. As of June 30, 2025 we had approximately $723 million of borrowing capacity available under our approximately $1.0 billion of superpriority series A and series B Revolving Credit Facilities (respectively, the “Series A Revolving Credit Facility” and “Series B Revolving Credit Facility,” and, together, the “Revolving Credit Facilities”), net of undrawn letters of credit issued to us thereunder. We typically use our Revolving Credit Facilities as a source of liquidity for operating activities and our other cash requirements. We had approximately $55 million of cash and cash equivalents outside the United States at June 30, 2025. We currently believe that 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 U.S. taxes or significant foreign taxes. We do not currently intend to repatriate to the United States any material amounts of our foreign cash and cash equivalents from operating entities.

Our senior leadership team and our Board of Directors review our sources and potential uses of cash in connection with our annual budgeting process and throughout the year as circumstances warrant. Generally speaking, our principal funding source is cash from operating activities, and our principal cash requirements include operating expenses, capital expenditures, income taxes, debt payments, periodic securities repurchases, periodic pension contributions, and other benefits payments.

Based on our current capital allocation objectives, during 2025 we project expending approximately $4.1 billion to $4.3 billion of capital expenditures.

For the 12-month period ending June 30, 2026, we project that our fixed commitments will include (i) $52 million of scheduled term loan amortization payments, (ii) $42 million of finance lease and other fixed payments, and (iii) $237 million of debt maturities.

As discussed elsewhere herein, on May 21, 2025, we entered into a definitive agreement to sell our Mass Markets fiber-to-the-home business in 11 states to AT&T for a pre-tax total of $5.75 billion in cash, subject to working capital and other various purchase price adjustments. The net proceeds from this sale, if consummated, as well as cash on hand, are expected to be used to pay down approximately $4.8 billion of Lumen Technologies, Inc. superpriority debt as described in Note 5—Long-Term Debt and Credit Facilities, which is expected to reduce our interest expense by approximately $300 million annually. The transaction is also expected to reduce our Mass Markets fiber-related capital expenditures by approximately $1 billion annually.

We believe that our cash and cash equivalents as of June 30, 2025 and current sources of funding will be sufficient liquidity to enable the Company to meet its cash requirements for at least the next 12 months. We will continue to monitor our future sources and uses of cash, and anticipate that we will make adjustments to our capital allocation strategies when, as and if determined by our senior leadership team and our Board. We may also draw on our Revolving Credit Facilities as a source of liquidity for operating activities and to give us additional flexibility to finance our capital investments, payments of debt, pension contributions, and other cash requirements.

On July 4, 2025, the U.S. enacted H.R.1, "A bill to provide for reconciliation pursuant to Title II of H. Con. Res. 14," commonly referred to as the One Big Beautiful Bill Act (the "OBBBA"). We are currently assessing the OBBBA's impact on our consolidated financial statements, including the income tax effects, which are discussed further under "Income Tax Obligations", below.

For additional information, see "Risk Factors—Financial Risks" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

Capital Expenditures

We incur capital expenditures on an ongoing basis to expand and improve our service offerings, enhance and modernize our networks, fulfill our contractual obligations, and compete effectively in our markets. We evaluate our discretionary capital expenditure projects based on a variety of factors, including expected strategic impacts (such as forecasted impact on revenue growth, productivity, expenses, service levels, and customer retention) and our expected return on investment. The amount of our capital investment is influenced by, among other things, current and projected demand for our services and products, our network and customer contract requirements, cash flow generated by operating activities, cash required for debt service and other purposes, regulatory considerations (such as governmentally-mandated infrastructure buildout requirements), and the availability of requisite supplies, labor, and permits.

Our capital expenditures continue to be focused on enhancing network operating efficiencies, developing new services, and expanding our fiber network, including our Private Connectivity FabricSM and Quantum Fiber buildout plans. A portion of our 2025 capital expenditures will also be focused on replacing aged network assets. For more information on our capital spending, see (i) "—Overview of Sources and Uses of Cash " above, (ii) "Cash Flow Activities—Investing Activities" below, and (iii) Item 1 of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

Debt Instruments and Financing Arrangements

Debt Instruments

On June 30, 2025, Level 3 Financing issued $2.0 billion of its 6.875% First Lien Notes due 2033. On such date, Level 3 Financing used the net proceeds from the offering, together with cash on hand, to redeem (i) all $925 million aggregate principal amount of Level 3 Financing's then-outstanding first lien 10.500% Senior Secured Notes due 2030, (ii) all $668 million aggregate principal amount of Level 3 Financing’s then-outstanding 10.500% First Lien Notes due 2029, and (iii) $167 million aggregate principal amount of Level 3 Financing’s outstanding 11.000% First Lien Notes due 2029, in each case including the payment of redemption premium and accrued interest, as well as related fees and expenses.

On March 27, 2025, Level 3 Financing (i) refinanced all of the outstanding secured Term Loan B-1 facilities and secured Term Loan B-2 facilities under its existing Credit Agreement, dated March 22, 2024 (the "2024 Level 3 Credit Agreement"), by and among Level 3 Financing, as borrower, Level 3 Parent, as guarantor, Wilmington Trust, National Association, as administrative agent and collateral agent, and the lenders from time to time party thereto and (ii) entered into an amendment to the 2024 Level 3 Credit Agreement (collectively, the "Credit Facilities Transactions"). This amendment revised the 2024 Level 3 Credit Agreement to, among other things, (i) reduce the pricing on Level 3 Financing’s term loan facility and make related changes to effect such repricing and (ii) extend the maturity of Level 3 Financing's term loan facility to 2032. Immediately following the Credit Facilities Transactions, Level 3 Financing had $2.4 billion of outstanding borrowings under its new secured Term Loan B-3 facility.

On February 15, 2025, (i) Lumen Technologies redeemed approximately $132 million aggregate principal amount of its unsecured senior notes and (ii) Level 3 Financing redeemed approximately $70 million aggregate principal amount of its unsecured senior notes, both in exchange for cash.

At June 30, 2025, we had:

$13.9 billion of outstanding consolidated secured indebtedness;

$4.4 billion of outstanding consolidated unsecured indebtedness (excluding (i) finance lease obligations, (ii) unamortized discounts, net, and (iii) unamortized debt issuance costs); and

approximately $723 million of unused borrowing capacity under our Revolving Credit Facilities, as discussed further below.

Under its credit agreements dated March 22, 2024, Lumen maintained at June 30, 2025 (i) approximately $1.0 billion of superpriority Revolving Credit Facilities, under which no amounts were outstanding as of such date, and had approximately $231 million of letters of credit issued and undrawn as of such date, and (ii) approximately $3.5 billion of drawn superpriority term loan facilities. Under the 2024 Level 3 Credit Agreement, Level 3 Financing, Inc. maintained at June 30, 2025, $2.4 billion of drawn secured term loan facilities.

At June 30, 2025, we had $234 million undrawn letters of credit outstanding, (i) $231 million of which were issued under our Revolving Credit Facilities and (ii) $3 million of which were issued under a separate facility maintained by other 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, Inc. are indebted under their respective outstanding senior notes, and certain of Lumen's other subsidiaries are indebted under their respective outstanding senior notes.

Subject to market conditions, we plan to continue to issue debt instruments from time to time to refinance a substantial portion of our maturing debt, including issuing debt securities of certain of our subsidiaries to refinance their maturing debt to the extent permitted under our debt covenants and consistent with our capital allocation strategies. The availability, interest rate, and other terms of any new borrowings will depend on the ratings assigned by credit rating agencies, among other factors.

As of the filing date of this report, the credit ratings for the senior secured and unsecured debt of Lumen Technologies, Inc., Level 3 Financing, Inc. and Qwest Corporation were as follows:

Borrower
Moody's Investors Service, Inc.(1)
Standard & Poor's
Fitch Ratings(1)
Lumen Technologies, Inc.:
UnsecuredCaa2CCCCCC-
SecuredB3/Caa1B+/CCCB+
Level 3 Financing, Inc.
UnsecuredCaa1CCCCCC-
SecuredB1/B3B+/B-B+/CCC
Qwest Corporation:
UnsecuredCaa2BB+
_______________________________________________________________________________
(1)In May and July 2025, Moody's and Fitch, respectively, placed all of Lumen, Level 3, and Qwest's ratings on review for a potential upgrade.

Our credit ratings are reviewed and adjusted from time to time by the rating agencies. Any future changes in the senior unsecured or secured debt ratings of us or our subsidiaries could impact our access to capital or borrowing costs. We cannot provide any assurances that we will be able to borrow additional funds on favorable terms, or at all. See "Risk Factors—Financial Risks" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

Table of Contents
From time to time over the past couple of years, we have engaged in various debt refinancings, redemptions, tender offers, exchange offers, open market purchases, and other transactions designed principally to reduce our consolidated indebtedness, extend our debt maturities, lower our interest costs, improve our financial flexibility, or otherwise enhance our debt profile. Subject to market conditions, restrictions under our debt covenants, and other limitations, we expect to opportunistically pursue similar transactions in the future to the extent feasible. See Note 5—Long-Term Debt and Credit Facilities to our consolidated financial statements in Item 1 of Part I of this report for additional information.

Income Tax Obligations

As of December 31, 2024, Lumen Technologies had approximately $570 million of federal net operating loss carryforwards ("NOLs") which, for U.S. federal income tax purposes, may be used to offset future taxable income. The majority of these NOLs were acquired through the Level 3 Communications, Inc. acquisition on November 1, 2017 and are subject to limitations under Section 382 of the Internal Revenue Code of 1986, as amended ("Section 382"). We maintain a Section 382 rights agreement designed to safeguard our ability to use those NOLs through late 2026. For additional information about our NOLs, see Note 16—Income Taxes to our consolidated financial statements in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024.

We expect to use substantially all of our remaining NOLs in future periods in accordance with Section 382's annual limitations, although we cannot guarantee this. See "Risk Factors—Financial Risks—We may not be able to fully utilize our NOLs" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

Tax legislation continues to evolve globally with new laws and regulations that create uncertainty in the global economy. On July 4, 2025, the U.S. enacted the OBBBA. The legislation, among other things, makes a favorable change to the business interest expense limitation and makes permanent 100% bonus depreciation for qualifying assets and immediate expensing for domestic research and experimentation expenses. As a result of the OBBBA, we expect our 2025 federal income tax liability to be significantly reduced and, accordingly, we have filed a refund claim for $400 million of federal estimated income taxes that we hope to receive later in 2025.

In addition, in December 2021, the Organization for Economic Co-operation and Development (OECD) 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. These global minimum tax rules have increased our administrative and compliance burdens but the impact to our financial statements is immaterial. We anticipate further legislative activity and administrative guidance throughout 2025 and continue to monitor evolving global tax legislation.

Pension and Post-retirement Benefit Obligations

We are subject to material obligations under our existing defined benefit pension plans and post-retirement benefit plans. At December 31, 2024, the accounting unfunded status of our qualified and non-qualified defined benefit pension plans and our qualified post-retirement benefit plans was $645 million and $1.7 billion, respectively. For additional information about our pension and post-retirement benefit arrangements, see "Critical Accounting Policies and Estimates—Pension and Post-retirement Benefits" in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2024; also see Note 11—Employee Benefits to our consolidated financial statements in Item 8 of Part II of the same report.

Benefits paid by our Combined Pension Plan are paid through the trust that holds the Combined Pension Plan's assets. Based on current laws and circumstances, we do not expect any contributions to be required for our Combined Pension Plan during 2025. The amount of required contributions to our 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. We occasionally make voluntary contributions to our plans in addition to required contributions and reserve the right to do so in the future. We currently do not expect to make a voluntary contribution in 2025.

Substantially all of our post-retirement health care and life insurance benefits plans are unfunded and are paid by us with available cash. Based on our most recent estimates, we expect to pay approximately $186 million of post-retirement benefits, net of participant contributions and direct subsidies, for the full year 2025. For additional information on our expected future benefits payments for our post-retirement benefit plans, see Note 11—Employee Benefits to our consolidated financial statements in Item 8 of Part II of our Annual Report Form 10-K for the year ended December 31, 2024.

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. See Note 11—Employee Benefits to our consolidated financial statements in Item 8 of Part II of our Annual Report Form 10-K for the year ended December 31, 2024 for additional information.

For 2025, our expected annual long-term rate of return on the pension plan assets is 6.5%. However, actual returns, if any, could be substantially different.

See Note 8—Employee Benefits to our consolidated financial statements in Item 1 of Part I of this report for more information.

Future Contractual Obligations

For information regarding our estimated future contractual obligations, see (i) the MD&A discussion included in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024 and (ii) updated information on short-term fixed debt commitments above under the heading "—Overview of Sources and Uses of Cash."

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 relinquished a portion of our RDOF awards in the third quarter of 2024. In the second quarter of 2025, we 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 will also incur fees in connection therewith. These fees are currently estimated to be $49 million and are reflected in our operating expenses within our consolidated statements of operations. We expect to remit the $95 million above, along with an additional $4 million relating to our 2024 relinquishment, in the latter half of 2025.

For additional information on these programs, see (i) Note 4—Revenue Recognition to our consolidated financial statements in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024, (ii) "Business—Regulation of Our Business" in Item 1 of Part I of the same Annual Report, and (iii) "Risk Factors—Legal and Regulatory Risks" in Item 1A of Part I of the same Annual Report.

Cash Flow Activities

The following table summarizes our consolidated cash flow activities for the six months ended June 30, 2025 and 2024.

 Six Months Ended June 30,$ Change
 20252024

(Dollars in millions)
Net cash provided by operating activities$1,665 1,613 52 
Net cash used in investing activities(1,642)(1,194)448 
Net cash used in financing activities(344)(1,160)(816)

Operating Activities

Net cash provided by operating activities increased by $52 million for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to an increase in deferred revenue related to receipt of advance cash payments pursuant to our recent sales of PCF solutions, partially offset by lower net income adjusted for non-cash expenses and gains, and receipt of a federal income tax cash refund in the first quarter of 2024. 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.

Investing Activities

Net cash used in investing activities increased by $448 million for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to increased capital expenditures and lower proceeds from sales of property, plant and equipment, and other assets.

Financing Activities

Net cash used in financing activities decreased by $816 million for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024, primarily due to higher net proceeds from issuance of long-term debt during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. These decreases were partially offset by higher net payments of long-term debt and revolving debt during the six months ended June 30, 2025, as compared to the six months ended June 30, 2024 and higher debt extinguishment costs and fees, driven by the debt transactions in 2025 compared to those in 2024 described elsewhere herein.

See Note 5—Long-Term Debt and Credit Facilities to our consolidated financial statements in Item 1 of Part I of this report for additional information on our outstanding debt securities.

Table of Contents
Other Matters

We have cash management and loan arrangements with a majority of our income-generating subsidiaries, in which a substantial portion of the aggregate cash of those subsidiaries is periodically advanced or loaned to us or our service company affiliate. Although we periodically repay these advances to fund the subsidiaries' cash requirements throughout the year, at any given point in time we may owe a substantial sum to our subsidiaries under these arrangements. In accordance with generally accepted accounting principles, these arrangements are reflected in the balance sheets of our subsidiaries but are eliminated in consolidation and therefore not recognized on our consolidated balance sheets. For additional information, see "Risk Factors" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

Our network includes some residual lead-sheathed copper cables installed years ago that constitute a small portion of our network. Recent media coverage of potential health and environmental risks associated with these cables has resulted in regulatory inquiries, and lawsuits, and could subject us to legislative or regulatory actions, removal costs, compliance costs, or penalties. As of June 30, 2025, we have not accrued for any such potential costs and will only accrue when such costs are probable and reasonably estimable. For additional information about related litigation and potential risks, see Note 12—Commitments, Contingencies and Other Items to our consolidated financial statements in Item 1 of Part I of this report, and the risk factor disclosures included under “Risk Factors” in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

We are also involved in various other legal proceedings that could substantially impact our financial position. See Note 12—Commitments, Contingencies and Other Items to our consolidated financial statements in Item 1 of Part I of this report for additional information.

Market Risk

As of June 30, 2025, we were exposed to market risk from changes in interest rates on our variable rate long-term debt obligations and fluctuations in certain foreign currencies.

Our management periodically reviews our exposure to interest rate fluctuations and periodically implements strategies to manage the exposure. From time to time, we have used derivative instruments to swap our exposure to variable interest rates for fixed interest rates. We have established policies and procedures for risk assessment and the approval, reporting, and monitoring of derivative instrument activities. As of June 30, 2025, we did not hold or issue derivative financial instruments for trading or speculative purposes.

As of June 30, 2025, we had approximately $6.0 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 $6.0 billion of unhedged floating rate debt would, among other things, decrease our annual pre-tax earnings by approximately $60 million.

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. Although we continue to evaluate strategies to mitigate risks related to the effect of fluctuations in currency exchange rates, we will likely continue to recognize 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.

Certain shortcomings are inherent in the method of analysis presented in the computation of exposures to market risks. Actual values may differ materially from those disclosed by us from time to time if market conditions vary from the assumptions used in the analyses performed. These analyses only incorporate the risk exposures that existed at June 30, 2025.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See "Liquidity and Capital Resources—Market Risk" in Item 2 of Part I above.

ITEM 4. 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 June 30, 2025. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2025, our disclosure controls and procedures were effective in providing reasonable assurance the information required to be disclosed by us in this report was accumulated and communicated in the manner provided above.

Changes in Internal Control Over Financial Reporting

Other than the implementation of controls over accounting for the divestiture of our Mass Markets fiber-to-the-home business in certain states, there have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the second quarter of 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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.

PART IIOTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS

The information contained under the subheadings "Principal Proceedings" and "Other Proceedings, Disputes and Contingencies" in Note 12—Commitments, Contingencies and Other Items to our consolidated financial statements included in Item 1 of Part I of this report is incorporated herein by reference. The ultimate outcome of the matters described in Note 12 may differ materially from the outcomes anticipated, estimated, projected, or implied by us in certain of our statements appearing in such Note, and proceedings currently viewed as not significant by us may ultimately materially impact us. For more information, see “Risk Factors—Legal and Regulatory Risks—Our pending legal proceedings could have a material adverse impact on us” in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024.

ITEM 1A. RISK FACTORS

Our operations and financial results are subject to various risks and uncertainties, which could adversely affect our business, financial condition, results of operations, or prospects. We recommend that you carefully consider (i) the other information set forth elsewhere in this report and (ii) the risk factors discussed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, as supplemented by the additional disclosures below:

We may not be able to complete our pending divestiture or realize the anticipated benefits thereof.

On May 21, 2025, we and certain of our affiliates agreed to sell our Mass Markets fiber-to-the-home business in 11 states and enter into various post-closing commercial agreements with the purchaser designed to ensure the continuity of services to customers. The completion of this divestiture is subject to receipt of several regulatory approvals and other customary closing conditions, the satisfaction of which is not assured and may not occur on the timeline that we expect. The pendency of this divestiture could impact us in several ways, including impacting relationships with our customers, vendors, and employees, restricting our operations, and diverting management’s attention from operating our business in the ordinary course. If we are unable to complete the divestiture as expected, we could face significant negative consequences, including negative reactions from the financial markets and challenges in achieving our debt reduction goals, which could adversely affect our credit ratings, and cause difficulty executing on our strategic priorities, objectives, or goals. We have also incurred significant costs, including the diversion of management resources, for which we will have received little or no benefit if the divestiture does not close.

Even if we successfully complete this divestiture, we may, among other things, (i) incur greater tax or other costs or realize fewer benefits than anticipated under the purchase agreement and the post-closing commercial agreements that we plan to enter into with the purchaser, (ii) experience operational difficulties segregating the divested assets from our retained assets, and (iii) experience losses or increased inefficiencies from stranded or underutilized assets. Moreover, these divestitures will reduce our future cash flows and result in certain dis-synergies. In addition, we may be exposed to ongoing obligations and liabilities associated with the divestiture, including as a result of any indemnification obligations.

Changes in U.S. and foreign government administrative policy, including the imposition of, or increases in, tariffs, and changes to existing trade agreements, could have a material adverse effect on us.

As a result of changes to U.S. and foreign government administrative policy, there may be changes to existing trade agreements, the imposition of or significant increases in tariffs on goods imported into the U.S. and adverse responses by foreign governments to U.S. trade policies, among other possible changes. The U.S. administration has implemented or increased tariffs and announced it intends to implement or increase additional tariffs, and it remains unclear what the U.S. administration or foreign governments will or will not do with respect to tariffs or trade agreements and policies. A trade war; other governmental action related to tariffs or trade agreements; changes in U.S. social, political, regulatory, and economic conditions or in laws and policies governing foreign trade, manufacturing, development, and investment in the territories and countries where we currently develop and sell products; and any resulting negative sentiments toward the U.S. as a result of such changes, could have a material adverse effect on our business, results of operations or financial condition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Background
Note 1— Background

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 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

Our consolidated balance sheet as of December 31, 2024, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe these consolidated financial statements include all normal recurring adjustments necessary to fairly state the results for the interim periods. The consolidated results of operations and cash flows for the first six months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024.

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: (i) income attributable to noncontrolling interests in other income, net, (ii) equity attributable to noncontrolling interests in additional paid-in capital, and (iii) cash flows from transactions attributable to noncontrolling interests in other, net financing activities.

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. See Note 4—Revenue Recognition and Note 11—Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses or net (loss) income for any period.
Summary of Significant Accounting Policies

Refer to the significant accounting policies described in Note 1— Background and Summary of Significant Accounting Policies to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024, as further supplemented below:

Assets Held for Sale

We classify assets and related liabilities as held for sale when: (i) management has committed to a plan to sell the assets; (ii) the net assets are available for immediate sale; (iii) there is an active program to locate a buyer; and (iv) the sale and transfer of the net assets is probable within one year. Assets and liabilities held for sale are presented separately on our consolidated balance sheets with a valuation allowance, if necessary, to recognize the net carrying amount at the lower of carrying value or fair value, less costs to sell. Depreciation of property, plant and equipment and amortization of finite-lived intangible assets and right-of-use assets are not recorded while these assets are classified as held for sale. For each reporting period that assets are classified as being held for sale, they are tested for recoverability. Unless otherwise specified, the amounts and information presented in the accompanying notes do not include assets and liabilities that have been reclassified as held for sale as of June 30, 2025. See Note 2 for information about our agreement to sell our Mass Markets fiber-to-the-home business in 11 states to AT&T and our classification of this business as held for sale on May 21, 2025.

Recently Adopted Accounting Pronouncements

Segments

We adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” for the year ended December 31, 2024. 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 11—Segment Information for more information on our segment reporting.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (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. This standard is effective for the annual period of fiscal 2026 and early adoption is permitted. As of June 30, 2025, we did not have any outstanding 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. This standard is effective for the annual period of fiscal 2027 and early adoption is permitted. The guidance will be applied prospectively, with the option for retrospective application. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

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 their 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 five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU will become effective for us for the annual reporting period ending December 31, 2025. The Income Taxes footnote to the consolidated financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2025 will align with the standard. We do not anticipate this standard will affect our operating results.

Planned Divestiture of the Mass Markets Fiber-to-the-Home Business

Discontinued Operations and Disposal Groups [Abstract]  
Planned Divestiture of the Mass Markets Fiber-to-the-Home Business
Note 2—Planned Divestiture of the 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 to AT&T for a pre-tax total of $5.75 billion in cash, subject to working capital and various other 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 we experience delays in completing the transaction or if there are changes in other assumptions that impact our estimates.

We do not believe this divestiture transaction represents a strategic shift for Lumen and therefore, does not meet the criteria to be classified as a discontinued operation. As a result, we will continue to report our operating results for the Mass Markets fiber-to-the-home business (the "disposal group") in our consolidated operating results until the transaction is closed. We anticipate closing this divestiture in the first half of 2026, upon receipt of all requisite regulatory approvals, as well as the satisfaction of other customary conditions.

As of June 30, 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 $22 million of depreciation for the three and six months ended June 30, 2025, if the disposal group did not meet the held for sale criteria.

Under the terms of the purchase agreement, Lumen agreed to grant the purchaser an indefeasible right to use (“IRU”) certain Lumen retained fiber assets following the close 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 June 30, 2025 are as follows:

(1)     As of June 30, 2025, this amount excluded goodwill classified as held for sale of approximately $1.3 billion. See Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business.
(2)    Certain customer relationships with a gross carrying value of $161 million and capitalized software with a gross carrying value of $211 million became fully amortized during 2024 and were retired during the first quarter of 2025.

As of June 30, 2025 and December 31, 2024, the gross carrying amount of goodwill, customer relationships, indefinite-lived, and other intangible assets was $13.1 billion and $15.4 billion, respectively.

Our goodwill was derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired. We report our results within two segments: Business and Mass Markets. See Note 11—Segment Information for more information on these segments.

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. 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 is October 31, at which date we assess our reporting units.

On May 21, 2025 (the date we agreed to sell the disposal group), we had three reporting units: (i) Mass Markets, (ii) North American Business ("NA Business"), and (iii) Asia Pacific region ("APAC"). 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.
We determined that the classification of the Mass Markets fiber-to-the-home business as held for sale as described in Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business 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 a non-cash, non-tax-deductible goodwill impairment charge of $628 million for the three and six months 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 impairments.

The following table shows the rollforward of goodwill assigned to our reportable segments from December 31, 2024 to June 30, 2025.

Operating Lease Revenue

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 income are included in Operating revenue in the consolidated statements of operations.

For the three months ended June 30, 2025 and 2024, our gross rental revenue was $265 million and $240 million, respectively, which represented approximately 9% and 7%, respectively, of our operating revenue for the three months ended June 30, 2025 and 2024. For the six months ended June 30, 2025 and 2024, our gross rental revenue was $527 million and $461 million, respectively, which represented approximately 8% and 7%, respectively, of our operating revenue for the six months ended June 30, 2025 and 2024.

(2)     As of June 30, 2025, this amount excluded $30 million of contract liabilities associated with the disposal group reclassified 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 three and six months ended June 30, 2025, we recognized $71 million and $365 million, respectively, of revenue that was included in contract liabilities of $733 million as of January 1, 2025, including contract liabilities that were classified as held for sale. During the three and six months ended June 30, 2024, we recognized $43 million and $343 million of revenue that was included in contract liabilities of $698 million as of January 1, 2024.

Performance Obligations

As of June 30, 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 June 30, 2025, the transaction price related to unsatisfied performance obligations that are expected to be recognized for the remainder of 2025, 2026, and thereafter was $1.6 billion, $2.1 billion and $2.3 billion, respectively.

These amounts exclude (i) the value of unsatisfied performance obligations for contracts for which we recognize revenue in amounts for 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), (ii) contracts that are classified as leasing arrangements or government assistance that are not subject to ASC 606, and (iii) the value of unsatisfied performance obligations for contracts which relate to the disposal group classified as held for sale.

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 on our consolidated balance sheets. We include the amount of deferred costs expected to be amortized beyond the next 12 months in Other liabilities on our consolidated balance sheets. We assess deferred acquisition and fulfillment costs for impairment on a quarterly basis.

2025 Debt Transactions

First Lien Note Refinancing

On June 30, 2025, Level 3 Financing, Inc. issued $2.0 billion of 6.875% First Lien Notes due 2033. On such date, Level 3 Financing used the net proceeds from the offering, together with cash on hand, to redeem (i) all $925 million aggregate principal amount of Level 3 Financing's then-outstanding first lien 10.500% Senior Secured Notes due 2030, (ii) all $668 million aggregate principal amount of Level 3 Financing’s then-outstanding 10.500% First Lien Notes due 2029, and (iii) $167 million aggregate principal amount of Level 3 Financing’s outstanding 11.000% First Lien Notes due 2029, in each case including the payment of redemption premium and accrued interest, as well as related fees and expenses (collectively, the "First Lien Note Refinancing").

The Company determined that the First Lien Note Refinancing constituted a debt extinguishment and recorded a loss of $236 million, which is included in our aggregate Net (loss) gain on early retirement of debt in Other (expense) income, net in our consolidated statement of operations for the three and six months ended June 30, 2025.
Credit Facilities Refinancing

On March 27, 2025, Level 3 Financing (i) refinanced all of the outstanding secured Term Loan B-1 facilities and secured Term Loan B-2 facilities under its existing Credit Agreement, dated March 22, 2024 (the "2024 Level 3 Credit Agreement"), by and among Level 3 Financing, as borrower, Level 3 Parent, as guarantor, Wilmington Trust, National Association, as administrative agent and collateral agent, and the lenders from time to time party thereto and (ii) entered into an amendment to the 2024 Level 3 Credit Agreement (collectively, the "Credit Facilities Transactions"). This amendment revised the 2024 Level 3 Credit Agreement to, among other things, (i) reduce the pricing on Level 3 Financing’s term loan facility and make related changes to effect such repricing and (ii) extend the maturity of Level 3 Financing's term loan facility to 2032. Immediately following the Credit Facilities Transactions, Level 3 Financing had $2.4 billion of outstanding borrowings under its new secured Term Loan B-3 facility.

The Company determined that the Credit Facilities Transactions constituted a debt extinguishment and recorded a loss of $35 million, which is included in our aggregate Net (loss) gain on early retirement of debt in Other (expense) income, net in our consolidated statement of operations for the six months ended June 30, 2025.

2024 Debt Transactions

For information on various issuances, exchanges, or payments of long-term indebtedness by Lumen or its subsidiaries during 2024, see Note 7—Long-Term Debt and Credit Facilities in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024.

Lumen Credit Agreements

Lumen is a party to (i) a Superpriority Revolving/Term A Credit Agreement, dated March 22, 2024, providing for superpriority series A and series B Revolving Credit Facilities (respectively, the “Series A Revolving Credit Facility” and “Series B Revolving Credit Facility,” and, together, the “Revolving Credit Facilities”) and a superpriority secured term loan facility (the “Lumen TLA”), (ii) a Superpriority Term B Credit Agreement, dated March 22, 2024, providing for two superpriority secured term loan facilities, maturing in 2029 and 2030, respectively (together, the “Lumen TLB”), and (iii) a credit agreement providing for Lumen's Term Loan B maturing in 2027, all of which are described in further detail in Note 7—Long-Term Debt and Credit Facilities— in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024.

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 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.

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.

As of June 30, 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.

Level 3 Financing Credit Agreement

As of June 30, 2025, Level 3 Financing had $2.4 billion of non-amortizing secured Term Loan B-3 outstanding under the term loan facility established by the 2024 Level 3 Credit Agreement (as amended through March 27, 2025, the "Level 3 Credit Agreement").

Borrowings under the term loan 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 facility will be 4.25%. The term loan facility is subject to a SOFR floor of 0.50%.

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 September 27, 2025). 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.

Senior Notes of Lumen and its Subsidiaries

The Company’s consolidated indebtedness at June 30, 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 primarily under (i) an uncommitted $225 million revolving letter of credit facility and (ii) the Revolving Credit Facilities.

At June 30, 2025, we had $234 million undrawn letters of credit outstanding, (i) $231 million of which were issued under the Revolving Credit Facilities and (ii) $3 million of which were issued under a separate facility maintained by other 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 will be 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 lien notes are secured by a first priority 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:

(i) 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 stepping down to 5.25 to 1.00 with respect to each fiscal quarter ending after December 31, 2025; or

(ii) 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 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 Companies

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 June 30, 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 June 30, 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.

As a result of ongoing efforts to reduce our workforce, we recognized a one-time charge of $2 million during the three months ended June 30, 2024 for special termination benefit enhancements paid to certain eligible employees upon voluntary retirement.

Our Combined 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. The amount of any future non-cash settlement charges will be dependent on several factors, including the total amount of our future lump sum benefit payments.
Benefits paid by the Combined Pension Plan are paid through a trust that holds the Plan's assets. The amount of required contributions to the Combined Pension Plan in 2025 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 expect to be required to make any additional contributions in 2025.

For the three months ended June 30, 2024, we excluded from the calculation of diluted loss per share less than 1 million shares potentially issuable under incentive compensation plans or convertible securities, as their effect, if included, would have been anti-dilutive due to our net loss position.

Our calculation of diluted (loss) earnings per common share excludes non-vested restricted stock awards that are anti-dilutive based upon the terms of the award. Such shares were 22.9 million and 24.1 million for the three months ended June 30, 2025 and 2024, respectively and 18.2 million and 22.2 million for the six months ended June 30, 2025 and 2024, respectively.

Fair Value of Financial Instruments
Note 10—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), interest rate swap contracts, 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 following table presents the carrying amounts and estimated fair values of our financial assets and liabilities as of June 30, 2025 and December 31, 2024:

Segment Information
Note 11—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.

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 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 the three and six months ended June 30, 2025 and 2024, based on the segment categorization under which we were operating at June 30, 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 include 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

Commitments and Contingencies and Other Items
Note 12—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, at June 30, 2025 and December 31, 2024, we had accrued $76 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 in our consolidated balance sheets as of such dates. We cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $76 million accrual at June 30, 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.
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.

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.

Latin American Tax Litigation and 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. 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 10—Fair Value of Financial Instruments.
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 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. Preliminary estimates of potential damage claims against all defendants exceed $2 billion. A trial to determine liability only has been set for September 2025.

911 Surcharge

In June 2021, the Company was served with a complaint filed in the Santa Fe County District Court by Phone Recovery Services, LLC, acting on behalf of the State of New Mexico. The complaint claims Qwest Corporation and CenturyTel of the Southwest have violated the New Mexico Fraud Against Taxpayers Act since 2004 by failing to bill, collect, and remit certain 911 surcharges from customers. Through pre-trial proceedings, the Court narrowed the issues to be resolved by jury. On August 21, 2024, a jury decided the remaining issues, and consequently all claims asserted, in Lumen's favor. The parties filed and then withdrew appeals.

Minnesota State Income Tax Audit

On May 12, 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 income tax year. The Company intends to file a timely notice of appeal of the Order with the Minnesota Tax Court in the third quarter of 2025.

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 12 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. For additional information on our contingencies, see Note 18—Commitments, Contingencies and Other Items to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation
Basis of Presentation

Our consolidated balance sheet as of December 31, 2024, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe these consolidated financial statements include all normal recurring adjustments necessary to fairly state the results for the interim periods. The consolidated results of operations and cash flows for the first six months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024.

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: (i) income attributable to noncontrolling interests in other income, net, (ii) equity attributable to noncontrolling interests in additional paid-in capital, and (iii) cash flows from transactions 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.
Assets Held for Sale
Assets Held for Sale
We classify assets and related liabilities as held for sale when: (i) management has committed to a plan to sell the assets; (ii) the net assets are available for immediate sale; (iii) there is an active program to locate a buyer; and (iv) the sale and transfer of the net assets is probable within one year. Assets and liabilities held for sale are presented separately on our consolidated balance sheets with a valuation allowance, if necessary, to recognize the net carrying amount at the lower of carrying value or fair value, less costs to sell. Depreciation of property, plant and equipment and amortization of finite-lived intangible assets and right-of-use assets are not recorded while these assets are classified as held for sale. For each reporting period that assets are classified as being held for sale, they are tested for recoverability. Unless otherwise specified, the amounts and information presented in the accompanying notes do not include assets and liabilities that have been reclassified as held for sale as of June 30, 2025.
Recently Adopted and Issued Accounting Pronouncements
Recently Adopted Accounting Pronouncements

Segments

We adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” for the year ended December 31, 2024. 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 11—Segment Information for more information on our segment reporting.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (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. This standard is effective for the annual period of fiscal 2026 and early adoption is permitted. As of June 30, 2025, we did not have any outstanding 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. This standard is effective for the annual period of fiscal 2027 and early adoption is permitted. The guidance will be applied prospectively, with the option for retrospective application. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

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 their 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 five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU will become effective for us for the annual reporting period ending December 31, 2025. The Income Taxes footnote to the consolidated financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2025 will align with the standard. We do not anticipate this standard will affect our operating results.
