Part I

ITEM 1. BUSINESS

Overview

Infinera Corporation (“we,” “us,” “our”, “Infinera” or the "Company") is a semiconductor manufacturer and a global supplier of networking solutions comprised of networking equipment, optical semiconductors, software and services. Our portfolio of solutions includes optical transport platforms, converged packet-optical transport platforms, compact modular platforms, optical line systems, coherent optical engines and subsystems, a suite of automation software offerings, and support and professional services. Leveraging our U.S.-based compound semiconductor fabrication plant ("fab") and in-house packaging capabilities, we design, develop, and manufacture industry-leading indium phosphide-based photonic integrated circuits ("PICs") for use in Infinera’s vertically integrated, high-capacity optical communications products.

Our customers include operators of fixed line and mobile networks, including telecommunications service providers, internet content providers (“ICPs”), cable providers, wholesale carriers, research and education institutions, large enterprises, utilities and government entities. Our networking solutions enable our customers to deliver high-bandwidth business and consumer communications services. Our comprehensive portfolio of networking solutions also enables our customers to scale their transport networks as end-user services and applications continue to drive growth in demand for network bandwidth. These end-user services and applications include, but are not limited to, high-speed internet access, 4G/5G mobile broadband, cloud-based services, high-definition video streaming services, virtual and augmented reality, the Internet of Things (“IoT”), business Ethernet services and data center interconnect ("DCI").

As an optical semiconductor manufacturer, we specialize in the manufacturing of optical compound semiconductors using indium phosphide ("InP"). This technology is used in telecommunications networks to transmit massive amounts of data and power critical communications services like 5G, enhanced broadband, and high-capacity data center connectivity. Infinera has made significant investments in our unique research, development, fabrication, and packaging facilities, including our optical compound semiconductor fab in Silicon Valley. We optimize the manufacturing process by using InP to build our PICs, which enables the integration of hundreds of optical functions onto a single, monolithic optical semiconductor chip. The unique capabilities of our optical semiconductor fab, which has provided our customers with a critical and secure source of U.S.-produced optical semiconductors and strengthened the supply chain, have enabled us to consistently pioneer critical technology advancements. For example, our latest generation of technology has made it possible to transmit information at a rate of 800 gigabits per second (“Gb/s”) using a single laser.

We support U.S. government efforts to advance and increase the domestic manufacturing base for semiconductors as a matter of economic and national security. Compound semiconductors – including those based in InP – are an important part of the domestic semiconductor industry and will enable the next-generation of leading-edge technologies. Domestic manufacturing is critical in order to reduce our reliance on foreign sources of compound semiconductor materials and components, which is essential to economic growth and to the security of our domestic communications infrastructure.

The large-scale integration of our PICs and advanced digital signal processors (“DSPs”) enables us to develop and manufacture high-performance optical engines that are used in our coherent optical networking system and subsystem solutions. These solutions include features that customers care about the most, including reduced cost per bit, lower footprint and power consumption, and improved performance, reliability and security. Coherent optical solutions are becoming increasingly important across the network as our customers transition to 800 Gb/s per wavelength transmission speeds and beyond in the core, 400 Gb/s in the metro, and 100 Gb/s in the access market segment. We believe our vertical integration strategy provides a competitive advantage by enabling leading optical performance at higher optical speeds with increased spectral efficiency, greater control over our supply chain, and a lower cost structure.

We have grown our solutions portfolio through internal development as well as acquisitions, including the acquisition of Telecom Holding Parent LLC (“Coriant”), a privately held global supplier of open network solutions for the largest global network operators (the “Acquisition”). These developments positioned us to be one of the leading providers of vertically integrated optical networking solutions in the world with the ability to serve a global customer base with accelerated delivery of the innovative solutions our customers demand. In 2021, we announced an expansion of our portfolio with the introduction of a suite of coherent optical pluggables

designed to seamlessly address the rapidly growing market for point-to-point solutions as well as create a new category of point-to-multipoint solutions that can enable a dramatically more cost-efficient network architecture. Based on our vertically integrated optical semiconductor technology and supporting a range of high-speed transport rates that include 800 Gb/s, 400 Gb/s and 100 Gb/s, this suite of coherent optical pluggables builds on our history of delivering innovative, highly differentiated, and vertically integrated coherent optical engines.

Our products are designed to be managed by a suite of software solutions that enable simplified network management and automated operations. We also provide software-enabled programmability that offers differentiated capabilities such as Instant Bandwidth. Combined with our differentiated hardware solutions, Instant Bandwidth enables our customers to purchase and activate bandwidth as needed through our unique software licensing feature set. This, in turn, allows our customers to accomplish two key objectives: (1) limit their initial network startup costs and investments; and (2) instantly activate new bandwidth as their customers’ and their own network capacity needs evolve.

We believe our systems and subsystems portfolios benefit our customers by providing a unique combination of highly scalable capacity and features that address access to core transport network applications and ultimately simplify and automate network operations. Our high-performance optical transport solutions leverage the industry shift to open optical network architectures and enable our customers to efficiently and cost-effectively meet bandwidth demand, which continues to grow 30% or more year-over-year.

We were incorporated in December 2000 and originally operated under the name “Zepton Networks.” We are incorporated in the State of Delaware. Our principal executive offices are located at 6373 San Ignacio Avenue, San Jose, CA 95119. Our telephone number is (408) 572-5200. “Infinera,” “FlexCoherent,” and the Infinera logo, are trademarks or service marks of Infinera Corporation in the United States, certain other countries and/or the European Union. Any other trademarks or trade names mentioned are the property of their respective owners.

Industry Background

Optical transport networking equipment carries digital information using light waves over fiber optic cables. With the advent of dense wavelength division multiplexing (“DWDM”) systems, data is transmitted by using multiple wavelengths of light using different frequencies or colors over a single optical fiber. Customers deploy DWDM systems to carry information between continents, across countries, between cities and within metropolitan areas, and in some cases all the way to the end-user. Fiber optic networks are generally capable of carrying most types of communications traffic. Coherent optical technology is the latest innovation in DWDM transmission solutions, dramatically increasing the amount of information a single laser can transmit.

We believe that a number of trends in the communications industry are driving demand for large amounts of network bandwidth and ultimately will increase demand for advanced optical transport networking solutions. These trends include:

•growth of cloud services;

•growth of over-the-top services and high-definition video streaming;

•growth of mobile broadband services, including 4G and emerging 5G services;

•growth of edge computing resources closer to end-users;

•increasing use of connected virtual and augmented reality devices; and

•the IoT, which continues to drive massive growth in the number of network-connected devices.

As network traffic grows, network operators will need to continue to add transmission capacity to existing optical networks or deploy new systems and/or subsystems to address bandwidth demand and offer new end-user services.

We believe we are in the midst of an important shift in transport network architectures that impact the markets we serve. The shift to open and disaggregated networks is increasingly being embraced by the communications industry. Examples of this trend include separation of compute, storage, and networking in data centers, the separation of hardware, operating system and applications in smart phones, hardware/software separation in network function virtualization and hardware and software routing stack routers, and open radio access network initiatives for 5G. Industry evolution is now enabling optical networking to leverage these same principles of openness and disaggregation.

Optical networking technology has evolved to enable open networks at the physical and management layer. These technologies allow network operators to move from a traditional vendor locked-in model to a more flexible model where they can choose from a collection of modular, best-of-breed solutions from different suppliers for each network function. Open and standards-based interfaces ease the integration into a unified network architecture.

The shift to open optical networking provides network operators with key benefits that include:

•Accelerated innovation cycles: By leveraging the full innovation capabilities of the optical ecosystem, network operators are able to select best-in-class technologies and vendors independently throughout the network lifecycle. Solution providers can also develop innovative technologies for specific network functions without having to supply end-to-end networking solutions, significantly broadening the innovation ecosystem.

•Optimized network architectures: By selecting the ideal products and technologies for each layer and domain of the network independently, network operators are able to optimize their optical network for specific applications and services and avoid the constraints of a single-vendor for one-size-fits-all solutions.

•Improved network economics: Open optical networks enable cost-per-bit reducing innovations to be quickly deployed throughout the network lifecycle, with customized multi-vendor network designs providing additional scope for cost-optimization as capacity and service demands evolve.

A second shift is happening at the edge of the network, where capacity is growing beyond the ability of traditional, non-coherent optical solutions to address. This increasing capacity demand is driving the need for innovative edge- and access-optimized coherent optical transport solutions. These include more compact, efficient and cost-effective solutions as well as innovative coherent optical pluggable solutions such as ICE-X optics point-to-point and point-to-multipoint technology that can enable significant cost savings by simplifying network architectures.

Strategy

Our goal is to be the preeminent provider of high-performance transport technologies and solutions that enable our customers to cost-efficiently scale network capacity and launch new services in response to increasing end-user bandwidth demand. Key aspects of our strategy include:

•Leveraging our U.S.-based optical semiconductor fab and packaging capabilities and vertically integrated solutions to deliver lowest total cost network solutions. We will continue to provide our customers with differentiated value by leveraging our vertically integrated optical engine. Our strategy is to continue to evolve our unique optical technology with higher speed and increasingly efficient capabilities, integrating our vertically integrated optical engines across a broad range of our open optical networking systems and expanding our addressable market with a suite of with vertically integrated subsystem and coherent optical pluggable solutions.

•Driving cost structure optimization and achieving cost advantages of scale. Leveraging scale as part of our vertical integration strategy, which includes integration of our optical engine across our broad portfolio of systems and subsystems, enables us to achieve cost advantages and cost structure efficiencies that enhance our ability to continue to invest in research and development in our optical engine and end-to-end portfolio, as well as drive profitability. In particular, we believe our vertically integrated in-house optical semiconductor manufacturing capabilities serve as a competitive advantage from a technology and supply chain perspective and enable a lower cost structure and higher profitability.

•Building open optical networking solutions. Our strategy is focused on leveraging open optical networking principles, including disaggregated networking solutions and industry-leading optical technology with open application programming interfaces (“APIs”) and standardized data models to offer our customers best-in-class solutions and create insertion opportunities to gain market share. Open optical networking provides benefits for both network operators and innovative solution providers. These benefits include accelerating innovation cycles, enabling optimized and differentiated networking solutions, and the ability to transform network economics.

•Delivering a superior customer experience. Our success will continue to be driven by our commitment to providing a superior experience to all customers. In addition to product delivery

capability that efficiently and predictably delivers innovative technology and high-quality products to market, we bring value to our customers by providing differentiated capabilities that include usage-based bandwidth provisioning, service agility and ease-of-use that accelerates time-to-revenue. Additionally, our global customer services team is committed to making our customers successful by providing the highest quality support services that help our customers deploy, operate and maintain their networks. We believe our technology leadership combined with our ability to provide the most reliable products and a differentiated customer experience contribute to customer success and represent major differentiators.

Competition in the optical transport systems market is intense, with consolidation and geopolitical market shifts creating new competitive dynamics. In the long-haul market, our main competitors include DWDM systems suppliers such as Ciena, Huawei, Nokia and ZTE. In the metro market, we face the same competitors as in long-haul, in addition to Cisco, ADVA Optical Networking, Ribbon Communications, and Fujitsu, among others. In the DCI market we also face competition from vendors that are selling optical components such as pluggable optics directly to customers as opposed to DWDM systems. In addition to our current competitors, other companies have developed, or may in the future develop, system and subsystem products that are, or could be, competitive with our products. This includes companies such as Lumentum, Marvell, II-IV and potential competitors in China. We also may encounter competitor consolidation in the markets in which we compete, which could lead to a changing competitive landscape, capabilities and market share, and could impact our results of operations.

Some of our competitors have substantially greater name recognition, technical, financial, sales and marketing resources and may be perceived by our customers and suppliers to have greater financial stability, and better-established relationships with potential customers than we have. Many of our competitors have more resources and more experience in developing or acquiring new products and technologies, and in creating market awareness for those products and technologies. In addition, many of our competitors have the financial resources to offer competitive products at aggressive pricing levels that could prevent us from competing effectively. Further, many of our competitors have built long-standing relationships with some of our prospective and existing customers and have the ability to provide financing to customers and could, therefore, have an inherent advantage in selling products to those customers.

Sales and Marketing

We market and sell our products and related support services primarily through our direct sales force, supported by marketing and product management personnel. We also use distribution or support partners to enter new markets or when requested by a potential customer. Our sales team has significant experience with the buying process and sales cycles typical of high-value telecommunications products.

The sales process for our products entails discussions with prospective customers, analyzing their networks and identifying how they can utilize our systems capabilities within their networks. This process requires developing strong customer relationships and leveraging our sales force and customer support capabilities.

Over the course of the sales cycle, potential customers often test our products before buying. Prior to commercial deployment, the customer will generally perform a field trial of our products. Upon successful completion, the customer generally accepts the products installed in its network and may continue with commercial deployment of additional products. We anticipate that our sales cycle, from initial contact with a prospective customer through the signing of a purchase agreement may, in some cases, take several quarters.

Direct Sales Force. Our sales team sells directly to service providers worldwide and is organized geographically around the following markets: (i) United States and Canada (“North America”); (ii) Latin America and South America (“LATAM”); (iii) Europe, Middle East and Africa (“EMEA”); and (iv) Asia Pacific and Japan (“APAC”). Within each geographic area, we maintain specific teams or personnel that focus on a particular region, country, customer or market vertical. We believe that we will need to further invest in the growth of our direct sales force to compete effectively against our competitors that have built long-standing relationships with some of our prospective and existing customers.

Indirect Sales Force. We employ business consultants and resale and logistics partners to assist in our sales efforts. These partners have deep knowledge of regional business practices and strong relationships with key local operators. We expect to work with business partners to assist our customers in the sale, deployment and maintenance of our systems and have entered into distribution and resale agreements to facilitate the sale and support of our products.

Marketing and Product Management. Our product management team is responsible for defining the product features and go-to-market plan required to maximize our success in the marketplace. Product management supports our sales efforts with product and application expertise. Our corporate marketing team works to create demand for our products by communicating our value proposition and differentiation through direct customer interaction, public relations, attendance at trade shows and other events, as well as internet programs and other marketing channels.

Research and Development

Continued investment in research and development is critical to our business. To this end, we have a team of engineers with expertise in various fields, including photonic integrated circuits, components, systems, sub-systems and software. Our research and development efforts are currently focused in San Jose, California; Allentown, Pennsylvania; Annapolis, Maryland; Bangalore and Ahmedabad, India; Kanata, Canada; Stockholm, Sweden; Munich, Germany; Lisbon, Portugal; and Shanghai, PRC. We utilize a mix of internal resources and supplement our staffing with development personnel provided by third parties on a contract basis. We have invested significant time and financial resources into the enhancement of existing products and the development of new products. We will continue to expand our product offerings and the capabilities of existing products in the future and plan to dedicate significant resources to these continued research and development efforts. We are continually increasing the scalability and software features of our current platforms. We are investing in leveraging our vertical integration capabilities across a broader portion of our platforms. We are also working to develop new generations of optical engines at a faster cadence than we have historically in order to bring new products to market more rapidly and meet evolving customer demands. We believe these efforts will enhance our

competitiveness in the markets we currently serve and also allow us to address adjacent markets to fuel our future growth.

Human Capital

Integrity, trust, mutual commitment and respect for diversity are core Infinera values – values brought to life by our talented, diverse, and dedicated global workforce. Employee health and safety are also cornerstones of our human capital management. Our goal is to continuously improve employee engagement as we strive to build and maintain a culture of human connection, individual responsibility and mutual integrity. As of December 31, 2022, we had 3,267 employees, with 2,018 of those employees located outside of the United States. None of our U.S. employees are subject to a collective bargaining agreement. Employees in certain foreign jurisdictions are represented by local workers’ councils or collective bargaining agreements, as required by local laws or customs. We have not experienced any work stoppages to date. We consider the relationships with our employees to be positive.

Diversity, Equity and Inclusion

At Infinera, we strive to create an inclusive culture, as reflected in the way we treat each other, the way we respect our differences across our global workforce, and how we conduct business with our customers and partners around the world. We believe that our culture of inclusion and belonging enables us to leverage the strengths of our people to exceed customer expectations and growth objectives. Our global diversity, equity, and inclusion (“DEI”) engagement committee drives our key DEI initiatives, which include training and development, employee resource groups (“ERGs”), and recruiting and retention strategies.

In 2020, we launched Infinera ALL-In, an employee-led, executive-sponsored, company-wide effort to promote, facilitate and support sustainable DEI efforts. ALL-In is sponsored by our Chief Executive Officer ("CEO"), Chief Financial Officer ("CFO"), and Chief Human Resources Officer ("CHRO"), and led by other executives and employee leaders from each region in which we have employees and do business. ALL-In has contributed to our inclusive culture, raised awareness and fostered meaningful dialogue, and helped guide the overall development of our DEI initiatives.

In 2021, we expanded our DEI global team with the addition of local DEI representatives at our major sites who are helping to develop, support, and scale our DEI initiatives and employee engagement activities at the local level. In 2022, we invested in fostering a more inclusive work environment. In the U.S., we have commenced partnerships with non-profits and historically black colleges and universities to increase our pipeline of diverse talent. In our larger sites globally, we provide training on inclusive hiring and are posting roles on platforms and job boards targeted at diverse talent pools enabling greater access to diverse talent.

Employee engagement is critical to building a unified and global culture that values local needs and perspectives. To foster inclusion and promote these efforts, we support several ERGs, including African Descent/Black at Infinera, Latin America, and Women at Infinera ("WIN").

WIN works to provide our female employees with access to conferences, networking events and other prominent engagements in the technology industry, as well as to support greater opportunities for career growth, internships, and leadership. In 2022, we continued to expand WIN activities and participation, including the introduction of our mentoring program, the formation of subcommittees, and a speakers’ program addressing topics including development, recruitment and retention of women. In various locations, employees have also partnered with local nonprofits and schools to encourage female students to pursue STEM careers.

In 2022, we continued to provide DEI training for our global employee base. Training topics are focused on global diversity, employees' roles in workplace diversity and related matters. Recruiters and managers participate in training on topics such as ensuring a diverse applicant pool and overcoming unconscious bias in the workplace and in interviews.

In addition, we launched a global employee survey in 2022 which included questions on DEI matters. The positive results and constructive feedback from this survey will enable us to accelerate program development to advance DEI progress at Infinera.

As of December 31, 2022, women represented 19% of our global employees and minorities represented approximately 37% of our U.S. workforce.

Compensation, Benefits and Well-being

Our goal is to incentivize our talented employees with a total compensation package that is market-competitive as validated through independent data sources. Our total compensation for eligible employees includes base salary, bonuses and equity awards. We intend to maintain ongoing competitiveness for attracting and retaining talent. We continuously improve our human resources information systems for workforce data collection, monitoring, and reporting, and expect that this will allow us to improve our understanding of compensation equity around the globe to ensure fair pay. We also seek to provide market-competitive benefits as part of our total reward structure for all employees around the globe and their dependents. In 2022, we conducted a global gender-based pay equity assessment and a race-based pay equity assessment in the U.S. to support consistency and equity in our pay practices.

We have also invested in creating physically safe work environments for our essential on-site workforce, which is important given our status as a critical infrastructure business with manufacturing facilities in the U.S. and research and development sites in several countries. To advance these efforts, we have a global leadership team comprised of local site leaders that meets regularly to support compliance with all local and international guidelines and establishes best practices at every site. We are committed to providing employees with a healthy and safe work environment by striving to prevent accidents and improve workplace conditions, and continuously working to improve our processes and performance. Our health and safety programs emphasize personal accountability, professional conduct, and regulatory compliance, while our culture fosters a sense of proactivity, caution, empathy and communication.

In the U.S., we have also continued to support COVID-19 testing for essential on-site employees at no cost to employees. We also provide paid leave to employees who contract COVID-19, which in many cases is beyond what is required by local laws.

We have also continued to emphasize employee well-being. For example, in the U.S., the Employee Assistance Program benefit includes mental health counseling for help with personal issues, childcare and eldercare referrals, financial coaching, legal consultation and wellness tools. Employees are provided medical, dental, vision, long-term and short-term disability, and life insurance, and employees covered under our health insurance have access to various wellness programs. Employees are provided paid parental leave as new parents (birth or adoption). Eligible employees are also qualified to receive unlimited flexible time off. We also provide training on matters such as working effectively with teams in a remote environment and making meetings more effective.

Growth and Development

We believe that transparency and integrity help foster a culture of professional growth. We continuously evolve our approach to employee communication, from a company-wide perspective to functional communication to smaller team meetings, all the way to one-on-one discussions. With that in mind, we encourage our employees to share candid feedback about working for our company through feedback channels, including employee surveys and on public forums such as Glassdoor.com. Our management utilizes this feedback as we work to consistently improve our employee experience.

We have also expanded our WIN mentorship program to become a global mentorship program to empower all employees within Infinera to advance their careers and realize their full potential. By facilitating mentor-mentee relationships, this program provides a unique opportunity for reflection, self-examination, and the development of practical skills for mentees while simultaneously providing mentors with fresh perspectives, insights, opinions and an opportunity to have a direct hand in the development of future leaders.

Experiential learning is powerful in career development, which is why we provide global job-based learning opportunities including cross-functional transfers and expanded roles. Education also enables the advancement of our DEI initiatives, which is one of our core values and a continued area of focus for us. In 2022, we also significantly expanded our learning and development initiatives, including the rollout of a scalable, multi-language e-learning platform that enables the proliferation of global, diverse and professional education.

Manufacturing

We have invested significant time and capital to develop and improve the manufacturing processes we use to produce and package our products. This includes significant investments in personnel, equipment and the facilities needed to manufacture and package our products in California and Pennsylvania. We also have invested in automating our manufacturing process and in training and maintaining the quality of our manufacturing workforce. As a leader in the development of photonic integration, our manufacturing processes have been developed over many years and are protected through a combination of patents, trade secrets and contractual protections. We believe that the investments we have made towards the manufacturing and packaging of our products provide us with a significant competitive advantage. We also believe that our current manufacturing facilities, including our fabrication facility for our PICs in California and our module manufacturing facility in Pennsylvania, can accommodate an increase in production capacity as our business continues to grow.

We also use contract manufacturers to assemble portions of our products. Each contract manufacturer procures components necessary to assemble products according to our specifications and bills of material. For elements of our business where we outsource, we perform rigorous in-house quality control testing to ensure the reliability of our products. Our supply chain risk mitigation strategies are continuous and institutionalized in our supply chain design for external manufacturing and for procurement of components. We currently use three contract manufacturers in several different countries, including Thailand, Malaysia, China, Mexico and Hungary, and we maintain the capability to transfer select manufacturing activities to U.S. qualified factories of three electronic manufacturing services partners.

We expect all suppliers to comply with our Supplier Code of Conduct, which addresses the rights of workers to safe and healthy working conditions, environmental responsibility, and compliance with applicable laws.

Backlog

Our backlog represents purchase orders received from customers for future product shipments and services to be provided in future periods. Our backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, purchase orders may be canceled without penalty. Orders in backlog may be fulfilled several quarters following order receipt and may relate to multi-year support service obligations. As a result, we believe that backlog should not be viewed as an accurate indicator of future operating results for any particular period. A backlogged purchase order may not result in revenue in a particular period, and the actual revenue may not be equal to our backlog amounts. Our presentation of backlog may not be comparable with that of other companies in our industry.

Intellectual Property

Our innovative software and optical engine technologies, including our PIC, DSP, module and related technologies, are foundational to our products and we believe they are highly valued by our customers and provide us with a competitive advantage.

We believe our success depends upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections. However, there can be no assurances that these protections will be sufficient to provide us with a competitive advantage or that others have not or will not reverse engineer our designs or discover, develop or disclose the same or similar designs and manufacturing processes.

As of December 31, 2022, we held 1,054 U.S. patents and 497 international patents expiring between 2023 and 2042, and held 177 U.S. and 116 foreign pending patent applications. We do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims.

We may not receive any competitive advantages from the rights granted under our patents and other intellectual property. Any patents granted to us may be contested, circumvented or invalidated over the course of our business, and we may not be able to prevent third parties from infringing these patents. Therefore, the impact of these patents cannot be predicted with certainty.

We believe that the frequency of assertions of patent infringement is increasing as patent holders, including entities that are not in our industry and who purchase patents as an investment or to monetize such rights by obtaining royalties, use such actions as a competitive tactic as well as a source of additional revenue.

For example, we are currently involved in litigation for alleged patent infringement. See the information set forth under the heading “Legal Matters” in Note 13, Commitments and Contingencies, in Part II, Item 8 for additional information regarding such litigation. Any claim of infringement from a third party, even those without merit, could cause us to incur substantial costs defending against such claims, and could distract our management from running our business. Furthermore, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages or could include an injunction or other court order that could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual property, which may not be available on commercially reasonable terms or at all. Alternatively, we may be required to develop non-infringing technology, which would require significant effort and expense and may ultimately not be successful.

In addition to trade secret and patent protections, we generally control access to and the use of our proprietary software and other confidential information. This protection is accomplished through a combination of internal and external controls, including contractual protections with employees, contractors, customers and partners, and through a combination of U.S. and international copyright laws.

We license some of our software pursuant to agreements that impose restrictions on our customers’ ability to use such software, such as prohibiting reverse engineering and limiting the use of copies. We also seek to avoid disclosure of our intellectual property by relying on non-disclosure and assignment of intellectual property agreements with our employees and consultants that acknowledge our exclusive ownership of all intellectual property developed by the individual within the scope of and during the course of his or her work with us. The agreements also require that each person maintain the confidentiality of all proprietary information disclosed to them. Other parties may not comply with the terms of their agreements with us, and we may not be able to enforce our rights adequately against these parties. We also rely on contractual rights to establish and protect our proprietary rights in our products.

We incorporate free and open source licensed software into our products. Although we monitor our use of such open source software closely, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In addition, non-compliance with open source software license terms and conditions could subject us to potential liability, including intellectual property infringement and/or contractual claims. In such event, we could be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished in a timely manner, any of which could adversely affect our business, operating results and financial condition.

Governmental Regulations

Environmental Laws and Regulations. We are committed to maintaining compliance with all environmental laws and regulations applicable to our operations, products and services. Our business and operations are subject to various federal, state, local and foreign laws and regulations that have been adopted with respect to the environment, including the Waste Electrical and Electronic Equipment Directive ("WEEE"), Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment ("RoHS"), and Registration, Evaluation, Authorization, and Restriction of Chemicals ("REACH") regulations adopted by the European Union. Environmental regulation is increasing and we expect that our operations will be subject to additional environmental compliance requirements, which may expose us to additional costs. We are also subject to disclosure requirements related to the presence of “conflict minerals” in our products. To date, our compliance costs relating to environmental regulations have not resulted in a material adverse effect on our business, results of operations or financial condition.

Other Laws and Regulations. We are subject to U.S. and foreign laws and regulations across the jurisdictions in which we operate. In addition to the environmental laws and regulations discussed above, we are subject to laws and regulations addressing the telecommunications industry, cybersecurity, privacy and data protection, export and import control, trade sanctions, and anti-bribery and anti-corruption. To date, our compliance costs relating to these laws and regulations have not resulted in a material adverse effect on our business, operating results or financial condition.

For further discussion of risks associated with these governmental laws and regulations, see Part I, Item 1A, “Risk Factors – Legal and Regulatory Risk Factors.”

•Our Loan Agreement and any other credit or similar agreements into which we may enter in the future may restrict our operations, particularly our ability to respond to changes or to take certain actions regarding our business.

•Our debt obligations may adversely affect our ability to raise additional capital and will be a burden on our future cash resources.

•Our international sales and operations subject us to additional risks.

•We may be adversely affected by fluctuations in currency exchange rates.

•Our effective tax rate may increase or fluctuate, which could increase our income tax expense and reduce our net income.

•We may issue additional shares of our common stock in connection with conversions of the 2024 Notes, the 2027 Notes and the 2028 Notes.

•The fundamental change provisions of the 2024 Notes, the 2027 Notes and the 2028 Notes may delay or prevent an otherwise beneficial takeover attempt of us.

•Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our common stock.

•Exclusive forum provisions in our bylaws will restrict our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or employees.

•Events that are outside of our control, such as natural disasters, terrorist attacks, wars, such as Russia's war with Ukraine, or other catastrophic events, could harm our operations.

For a more complete discussion of the material risks facing our business, see below.

Business and Operational Risk Factors

Our quarterly results may vary significantly from period to period, which could make our future results difficult to predict and could cause our operating results to fall below investor, analyst or our expectations.

Our quarterly results and, in particular, our revenue, gross margins, operating expenses, operating margins and net income (loss), have historically varied significantly from period to period and may continue to do so in the future. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Our budgeted expense levels are based, in large part, on our expectations of future revenue and the development efforts associated with that future revenue. Consequently, if our revenue does not meet projected levels in the short term, our inventory levels, cost of goods sold and operating expenses would be high relative to revenue, resulting in potential operating losses. If our revenue or operating results do not meet the expectations of investors or securities analysts or fall below any guidance we provide to the market, the price of our common stock may decline substantially.

Factors that may contribute to fluctuations in our quarterly results, many of which are outside our control and may be difficult to predict, include:

•fluctuations in demand, sales cycles and prices for products and services, including discounts given in response to competitive pricing pressures or to secure long-term customer relationships, as well as the timing of purchases by our key customers;

•the price, quality, timing of delivery and availability of key components from suppliers, including any price or shipping cost increases or delays in the supply of components that may result from supply disruptions as well as impacts due to consolidations amongst our suppliers;

•changes in customers’ budgets for optical transport network purchases and changes or variability in their purchasing cycles;

•fluctuations in our customer, product or geographic mix, including the impact of new customer deployments, which typically carry lower gross margins, customer consolidation, which may affect our ability to grow revenue, and products powered by our next-generation technologies, which initially tend to be lower margin due to higher per unit production costs and greater variability in production yields;

•the timing, market acceptance and rate of adoption of our new product releases and our competitors' new product releases;

•our ability to manage inventory while timely meeting customer demand and avoiding charges for excess or obsolete inventory;

•readiness of customers for installation of our products as well as the availability of third-party service partners to provide contract engineering and installation services for us, each of which has been impacted by the effects of the COVID-19 pandemic;

•any delay in collecting or failure to collect accounts receivable;

•the timing of revenue recognition and revenue deferrals;

•any future changes in U.S. GAAP or new interpretations of existing accounting rules;

•the impact of a significant natural disaster or public health emergency, as well as interruptions or shortages in the supply of utilities such as water and electricity, in a key location such as our Northern California facilities, which are located near major earthquake fault lines, in areas of high fire risk and in a designated flood zone; and

•general economic, market and political conditions in domestic and international markets, including those related to any policy changes by the federal government or by the presidential administration in the United States, and other factors beyond our control, including the ongoing effects of continuing inflation, rising interest rates and the COVID-19 pandemic and related response measures.

Our ability to increase our revenue will depend upon continued growth of demand by consumers and businesses for additional network capacity and on the level and timing of capital spending by our customers.

Our future success depends on factors that increase the amount of data transmitted over communications networks and the growth of optical transport networks to meet the increased demand for optical capacity. These factors include the growth of mobile, video and cloud-based services, increased broadband connectivity and the continuing adoption of high-capacity, revenue-generating services. If demand for such bandwidth does not continue, or slows down, the market for optical transport networking equipment may not continue to grow and our product sales would be negatively impacted.

In addition, demand for our products depends on the level and timing of capital spending in optical networks by service providers as they construct, expand and upgrade the capacity of their optical networks. Capital spending is cyclical in our industry and spending by customers can change on short notice. Any future decisions by our customers to reduce capital spending, whether caused by lower customer demand, weakening economic conditions, rising borrowing costs, inflation, customer-specific supply chain issues, changes in government regulations relating to telecommunications and data networks, or other reasons, could have a material adverse effect on our business, financial condition and results of operations.

Any delays in the development, introduction or acceptance of our new products or in releasing enhancements to our existing products may harm our business.

Our products are based on complex technologies, including, in many cases, the development of next-generation PICs, DSPs and specialized ASICs, each of which are key components of our optical engines. In addition, we may also depend on technologies from outside suppliers, all of which may cause us to experience unanticipated delays in developing, improving, manufacturing or deploying our products. The development process for our optical engines is lengthy, and any modifications entail significant development cost and risks.

At any given time, various new product introductions and enhancements to our existing products are in the development phase and are not yet ready for commercial manufacturing or deployment. We rely on third parties, some of which are relatively early-stage companies, to develop, manufacture and deliver components for our next-generation products, which can often require custom development. The development process from laboratory prototype to customer trials, and subsequently to general availability, involves a significant number of simultaneous efforts. These efforts often must be completed in a timely and coordinated manner so that they may be incorporated into the product development cycle for our systems, and include:

•completion of product development, including the development and completion of our next-generation optical engines, and the completion of associated module development;

•the qualification and multiple sourcing of critical components;

•validation of manufacturing methods and processes;

•extensive quality assurance and reliability testing and staffing of testing infrastructure;

•validation of software; and

•establishment of systems integration and systems test validation requirements.

Each of these steps, in turn, presents risks of failure, rework or delay, any one of which could decrease the speed and scope of product introduction and marketplace acceptance of our products. New generations of our optical engines as well as intensive software testing are important to the timely introduction of new products and enhancements to our existing products, which are subject to these development risks. In addition, unexpected intellectual property disputes, inability to obtain licenses to utilize third party development tools or other intellectual property on commercially acceptable terms, failure of critical design elements, limited or constrained engineering resources, and a host of other development execution risks may delay, or even prevent, the introduction of new products or enhancements to our existing products. If we do not develop and successfully introduce or enhance products in a timely manner, including the successful development of our next generation optical engine, our competitive position will suffer.

As we transition customers to new products, we face significant risk that our new products may not be accepted by our current or new customers. To the extent that we fail to introduce new and innovative products that are adopted by customers, we could fail to obtain an adequate return on these investments and could lose market share to our competitors, which could be difficult or impossible to regain. Similarly, we may face decreased revenue, gross margins and profitability due to a rapid decline in sales of current products as customers hold spending to focus purchases on new product platforms. In addition, the sale of new products may result in the cannibalization of sales for existing products, which may harm our results of operations. We could also incur significant costs in completing the transition, including costs of inventory write-downs of the current product as customers transition to new product platforms. In addition, products or technologies developed by others may render our products noncompetitive or obsolete and result in significant reduction in orders from our customers and the loss of existing and prospective customers. Any delays in the introduction of new components that we are developing for use in our other products as part of our vertical integration strategy may also prevent us from realizing the anticipated cost savings of such development. This may negatively impact our gross margins and harm our business and operating results.

Supply chain and logistics issues, including delays, shortages, components that have been discontinued and increased costs, and our dependency on sole source, limited source or high-cost suppliers, could harm our business and operating results.

We are reliant on our global supply chain for the production of components for our products. The global supply chain has experienced disruptions that began in 2020 as a result of the COVID-19 pandemic, leading to delays, shortages, components that have been discontinued and increased costs. These supply disruptions have negatively impacted our revenue and our results of operations. For example, shortages of certain key components have adversely affected our ability to deliver products to customers in a timely manner. Additionally, price increases within our supply chain have continued to negatively affect our gross margin. The global supply chain for components for our products, especially for semiconductor components, continues to experience shortages, longer lead times and increased costs. These shortages, delays and increased costs are expected to continue throughout 2023. We cannot predict with certainty the scope, magnitude or duration of the impact that these supply chain disruptions will have on our business and results of operations. Any efforts that we make to mitigate supply chain issues, such as by making additional or long-term purchase commitments with our suppliers or by holding higher levels of inventory, could negatively impact our financial results if we do not accurately forecast customer demand or if our customers change their purchasing patterns in response to the evolving supply chain environment. Further, the lead times required for these mitigation efforts may not allow us to meet increased customer demand in a timely manner.

We currently purchase several key components for our products from sole or limited sources. In particular, we rely on our own production of certain components of our products, such as PICs, and on third parties, including sole source and limited source suppliers, for certain of the components of our products, including ASICs, field-programmable gate arrays, processors, and other semiconductor and optical components. We have increased our reliance on third parties to develop and manufacture components for certain products, some of which require custom development. We purchase most of these components on a purchase order basis and generally only have long-term contracts with these sole source or limited source suppliers. If any of our sole

source or limited source suppliers suffer from capacity constraints, materials shortages, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output, they may be unable to meet our delivery schedule, which could result in lost revenue, additional product costs and deployment delays that could harm our business and customer relationships. In addition, these same suppliers may decide to no longer manufacture or support specific components necessary for some of our legacy products, which could lead to our inability to fulfill demand without increased engineering and material costs necessary to replace such components or cause us to transition such products to end-of-life status sooner than planned. Further, our suppliers could enter into exclusive arrangements with our competitors, refuse to sell their products or components to us at commercially reasonable prices or at all, go out of business or discontinue their relationships with us. We may be unable to develop alternative sources for these components within a suitable time frame to be able to operate our business, or at all.

The loss of a source of supply, or lack of sufficient availability of key components, could require us to redesign products that use such components, which could result in lost revenue, additional product and engineering costs and deployment delays that could harm our business and customer relationships. Due to cross dependencies, any supply chain disruptions could negatively impact the demand for our products in the short term. In addition, if our contract manufacturers do not receive critical components in a timely manner to build our products, then we would not be able to ship certain products in a timely manner and would, therefore, be unable to meet our prospective customers’ product delivery requirements. In the past, we have experienced delivery delays because of lack of availability of components or reliability issues with components that we were purchasing. In addition, some of our suppliers have gone out of business, merged with another supplier, or limited their supply of components to us, which may cause us to experience longer than normal lead times, supply delays and increased prices. We may in the future experience a shortage of certain components as a result of our own manufacturing issues, manufacturing issues at our suppliers or contract manufacturers, capacity problems experienced by our suppliers or contract manufacturers, strong demand in the industry for such components, or other disruptions in our supply chain. For example, during 2022, several of our materials suppliers with manufacturing facilities near Shanghai, China were affected by COVID-19-related quarantines, which have since been lifted. At certain times, these quarantines led to delayed shipments to certain of our contract manufacturers, which subsequently constrained the ability of these contract manufacturers to supply certain components to us on a timely basis. In addition, disruptions to global macroeconomic conditions may make it more difficult for us and our suppliers to accurately project overall component demand and manufacturing capacity. These supplier disruptions may continue to occur in the future, which could limit our ability to produce our products and cause us to fail to meet a customer’s delivery requirements. Any failure to meet our customers’ product delivery requirements could harm our reputation and our customer relationships, either of which would harm our business and operating results.

Aggressive business tactics by our competitors and new entrants may harm our business.

The markets that we compete in are extremely competitive, which often results in aggressive business tactics by our competitors and new entrants, including:

•aggressively pricing their optical transport products and other portfolio products, including offering significant one-time discounts and guaranteed future price decreases;

•offering optical products at a substantial discount or for free when bundled together with broader technology purchases, such as router or wireless equipment purchases;

•providing financing, marketing and advertising assistance to customers; and

•influencing customer requirements to emphasize different product capabilities, which better suit their products.

The level of competition and pricing pressure tend to increase when competing for large or high-profile opportunities or during periods of economic weakness when there are fewer network build-out projects. If we fail to compete successfully against our current and future competitors, or if our current or future competitors continue or expand their aggressive business tactics, including those described above, demand for our products could decline, we could experience delays or cancellations of customer orders or we could be required to reduce our prices to compete in the market.

The markets in which we compete are highly competitive and we may not be able to compete effectively.

The packet-optical equipment market is competitive. Our main competitors include DWDM system suppliers, such as ADVA Optical Networking, Ciena Corporation, Cisco Systems, Ribbon Communications Inc., Huawei Technologies Co., Ltd., Nokia and ZTE. In addition, there are several other companies that offer one or more products that partially compete with our offerings. Moreover, other companies have developed, or may in the future develop, products that are or could be competitive with our products. We also could encounter competitor consolidation in the markets in which we compete, which could lead to a changing competitive landscape, capabilities and market share, and could impact our results of operations. For example, in March 2021, Cisco completed its acquisition of optical communications supplier Acacia Communications.

Competition in the markets we serve is based on any one or a combination of the following factors:

•price and other commercial terms;

•functionality and optical performance;

•existing business and customer relationships;

•the ability of products and services to meet customers’ immediate and future network requirements;

•the availability of components required to manufacture key products;

•power consumption;

•heat dissipation;

•form factor or density;

•installation and operational simplicity;

•quality and reliability;

•service and support;

•security and encryption requirements;

•scalability and investment protection; and

•product lead times.

Some of our competitors have substantially greater name recognition and technical, financial, sales and marketing resources. Many of our competitors have more resources and more experience in developing or acquiring new products and technologies, and in creating market awareness for those products and technologies. In addition, many of our competitors have the financial resources to offer competitive products at aggressive pricing levels or have the ability to provide financing to customers, which could prevent us from competing effectively. Further, many of our competitors have built long-standing relationships with some of our prospective and existing customers and could, therefore, have an inherent advantage in selling products to those customers.

We also compete with low-cost producers that may increase pricing pressure on us and with a number of smaller companies that provide competition for a specific product, customer segment or geographic market. In addition, we may also face increased competition from system and component companies that develop products based on off-the-shelf hardware that offers the latest commercially available technologies. Due to the narrower

focus of their efforts, these competitors may achieve commercial availability of their products more quickly than we can and may provide attractive alternatives to our customers.

Product performance problems, including undetected errors in our hardware or software, or deployment delays could harm our business, results of operations and reputation.

The development and production of products with high technology content is complicated and often involves problems with hardware, software, components and manufacturing methods. Complex hardware and software systems that are built with and include increasingly sophisticated technology, such as our products, can often contain undetected errors or bugs when first introduced or as new versions are released. In addition, errors associated with components we purchase from third parties, including customized components, may be difficult to resolve. We have experienced issues in the past in connection with our products, including failures due to the receipt of components from our suppliers that are either faulty or do not meet our product specifications, and performance issues related to software updates. From time to time, we have had to replace certain components or provide software remedies or other remediation in response to errors or bugs, and we may have to do so again in the future. In addition, performance issues can be heightened during periods where we are developing and introducing multiple new products to the market, as any performance issues we encounter in one technology or product could impact the performance or timing of delivery of other products. Our products may also suffer degradation of performance and reliability over time.

If reliability, quality, security or network monitoring problems develop, a number of negative effects on our business could result, including:

•reduced orders from existing customers;

•declining interest from potential customers;

•delays in our ability to recognize revenue or in collecting accounts receivables;

•increased costs associated with fixing hardware or software defects or replacing products;

•high service and warranty expenses;

•delays in shipments;

•high inventory excess and obsolescence expense;

•high levels of product returns;

•diversion of our engineering personnel from our product development efforts; and

•payment of liquidated damages, performance guarantees or similar penalties.

Because we outsource the manufacturing of certain components of our products, we may also be subject to product performance problems as a result of the acts or omissions of third parties, and we may not have adequate compensating remedies against such third parties or otherwise implement effective measures to mitigate such problems.

From time to time, we encounter interruptions or delays in the activation of our products at a customer’s site. These interruptions or delays may result from product performance problems or from issues with installation and activation, some of which are outside our control, such as supply chain disruptions affecting our customers or us. For example, in 2022, we experienced project delays due to incomplete customer readiness and the unavailability of certain customer resources and customer-furnished material required for project implementation. If we experience significant interruptions or delays that we cannot promptly resolve, the associated revenue for these installations may be delayed or confidence in our products could be undermined, which could cause us to lose customers, fail to add new customers, and consequently harm our financial results.

The effects of the ongoing COVID-19 pandemic and other future public health concerns could have a material adverse effect on our business, manufacturing operations and results of operations.

While the effects of the COVID-19 pandemic have been decreasing, it has caused disruptions to our business and operations and could have a material adverse effect on our business and results of operations in the future. For example, the imposition of shelter-in-place or similarly restrictive work-from-home orders during the COVID-19 pandemic has in the past impacted, and could again impact, many of our offices and employees, and many of our employees continue to work remotely or in hybrid work environments. As a result of the public health and safety measures during the COVID-19 pandemic, we at times temporarily closed or substantially limited the presence of personnel in some of our offices, implemented travel restrictions and modified our participation in various industry events. Our flexible approach to work arrangements and related policies continues to evolve.

The COVID-19 pandemic has also at times contributed to delays in certain operational processes and it may again impact our operational processes. We have experienced disruption and delays in our global supply chain and manufacturing operations, logistics operations and customer support operations, including shipping delays, higher transport costs, and certain limitations on our ability to access customer fulfillment and service sites. We are dependent on sole source and limited source suppliers for several key components, and we have experienced capacity issues, longer lead times, increased costs and shortages with certain component suppliers, including for semiconductors, impacting our operational processes and results of operations. Some of these disruptions negatively impacted our revenue and our results of operations.

The impact of the COVID-19 pandemic and other future public health concerns on our business and results of operations in the future remains uncertain and is dependent in part on infection, morbidity and disability rates, the emergence of new viruses, the continued effectiveness and availability of vaccinations, and broader global macroeconomic developments. We may face further disruptions or restrictions on our ability to source, manufacture or distribute our products due to existing or additional governmental restrictions in multiple countries on business operations and movement of people and products. If we experience pronounced disruptions in our operations or in our ability to service our customers, including due to COVID-19 or other infections or quarantines among our employees and service providers, or if we face continued supply chain disruption or curtailed customer demand, these factors may materially adversely impact our business and results of operations. We could also face negative impacts on our liquidity and capital resources in the future due to the effects of the COVID-19 pandemic or other public health concerns, and their impacts on our customers, suppliers, third-party service providers and capital markets.

If we lose key personnel or fail to attract and retain additional qualified personnel when needed, our business may be harmed.

Our success depends to a significant degree upon the continued contributions of our key management, engineering, sales and marketing, and finance personnel, many of whom will be approaching retirement age in the next decade and many of whom would be difficult to replace. For example, senior members of our engineering team have unique technical experience that would be difficult to replace. Because our products are complex, we must also hire and retain highly trained customer service and support personnel to ensure that the deployment of our products does not result in network disruption for our customers. We believe our future success will depend in large part upon our ability to identify, attract and retain highly skilled personnel, and competition for these individuals is intense in our industry, especially in the San Francisco Bay Area where we are headquartered and, increasingly, in certain cities and regions where we have operations outside the United States as well. The loss of the services of any of our key personnel, the inability to identify, attract or retain qualified personnel in the future or delays in hiring qualified personnel, particularly engineers and sales personnel, could make it difficult for us to manage our business and meet key objectives, such as timely product introductions. These risks may be exacerbated due to a strong labor market with a competitive wage environment and attrition. In addition, we do not have long-term employment contracts or key person life insurance covering any of our key personnel. If we are unable to identify, attract and retain qualified personnel, we may be unable to manage our business effectively, and our results of operations could suffer.

We are dependent on a small number of key customers for a significant portion of our revenue from period to period and the loss of, or a significant reduction in, orders from one or more of our key customers would reduce our revenue and harm our operating results.

A relatively small number of customers accounts for a large percentage of our revenue from period to period. For example, for the year ended December 31, 2022, our top ten customers accounted for approximately 48% of our total revenue and one customer accounted for 11% of our total revenue. For 2021, our top ten customers accounted for approximately 42% of our total revenue and no customer accounted for 10% or more of our revenue. For 2020, our top ten customers accounted for approximately 43% of our total revenue and one customer accounted for 11% of our revenue. Our business will likely be harmed if any of our key customers, for whatever reason, substantially reduce, delay or stop their orders from us. In addition, our business will be harmed if we fail to maintain our competitive advantage with our key customers or do not add new large customers over time. We continue to expect a relatively small number of customers to continue to account for a large percentage of revenue from period to period. However, customer consolidation could reduce the number of key customers that generate a significant percentage of our revenue and may increase the risks relating to dependence on a small number of customers.

Our ability to continue to generate revenue from our key customers will depend on our ability to maintain strong relationships with these customers and introduce competitive new products at competitive prices. In most cases, our sales are made to these customers pursuant to standard purchase agreements, which may be canceled or reduced readily, rather than long-term purchase commitments that would require these customers to purchase any minimum or guaranteed volumes orders. In the event of a cancellation or reduction of an order, we may not have enough time to reduce operating expenses to minimize the effect of the lost revenue on our business. Our operating results will continue to depend on our ability to sell our products to our key customers. In addition, we must regularly compete for and win business with existing and new customers across all of our customer segments.

In addition, global economic conditions may affect the network spending, procurement strategies, or business practices of our key customers. If any of our key customers experience a loss in revenue due to weakening economic conditions, public health crisis, their corporate borrowing costs being materially impacted by rising interest rates, or other adverse occurrences, they may reduce or delay capital spending generally or with respect to our products, which could materially adversely affect our business and results of operations.

The manufacturing process for our optical engine and the assembly of our finished products are complex. The partial or complete loss of any of our manufacturing facilities, a reduction in yields of our PICs or an inability to scale capacity to meet customer demands could harm our business.

The manufacturing process for our optical engine, including the PICs, DSPs and specialized ASICs, and the assembly of our finished products are complex. In the event that any of our manufacturing facilities utilized to build these components and assemble our finished products was fully or partially destroyed, or shut down, as a result of a natural disaster, work stoppage or otherwise, it could severely limit our ability to sell our products. Because of the complex nature of our manufacturing facilities, such loss would take a considerable amount of time to repair or replace. The partial or complete loss of any of our manufacturing facilities, or an event causing the interruption in our use of any such facilities, whether as a result of a natural disaster, a public health crisis like the COVID-19 pandemic, work stoppage or otherwise, for any extended period of time, could cause our business, financial condition and results of operations to be harmed.

Minor deviations in the PIC manufacturing process can cause substantial decreases in yields and, in some cases, cause production to be suspended. In the past, we have had significant variances in our PIC yields, including production interruptions and suspensions, and may in the future have continued yield variances, including additional interruptions or suspensions. Lower than expected yields from our PIC manufacturing process or defects, integration issues or other performance problems in our products could limit our ability to satisfy customer demand requirements and could damage customer relations and harm our business, reputation and operating results.

Our inability to obtain sufficient manufacturing capacity to meet demand, either in our own facilities or through foundry or similar arrangements with third parties, could also harm our relationships with our customers, our business and our results of operations.

Increased consolidation among our customers and suppliers in the communications networking industry has had, and could continue to have, an adverse effect on our business and results of operations.

We have seen increased consolidation in the communications networking industry over the past few years, which has adversely affected our business and results of operations. Customer consolidation in the past has led to changes in buying patterns, slowdowns in spending, redeployment of existing equipment and re-architecture of parts of existing networks or future networks, as the combined companies evaluate the needs of the combined business. Moreover, the significant purchasing power of these large companies can increase pricing and competitive pressures for us, including the potential for decreases in our average selling prices. If one of our customers is acquired by another company that does not rely on us to provide it with products or relies on another provider of similar products, we may lose that customer’s business. Such consolidation may further reduce the number of customers that generate a significant percentage of our revenue and may exacerbate the risks relating to dependence on a small number of customers. Any of the foregoing results will adversely affect our business, financial condition and results of operations.

In addition, our suppliers in the communications networking industry have recently continued to consolidate. For example, II-VI acquired Finisar in 2019 and then acquired Coherent in 2022. Supplier consolidation may lead to increased prices of components for our products, deployment delays or a disruption in output. In addition, such consolidation may exacerbate the risks relating to our dependence on a small number of suppliers for certain components and materials that are required to manufacture our products.

If our contract manufacturers do not perform as we expect, our business may be harmed.

We rely on third-party contract manufacturers to perform a portion of the manufacturing of our products, and our future success will depend on our ability to have sufficient volumes of our products manufactured in a cost-effective and quality-controlled manner. We have engaged third parties to manufacture certain elements of our products at multiple contract manufacturing sites located around the world but do not have long-term agreements in place with some of our manufacturers and suppliers that would guarantee product availability, or the continuation of particular pricing or payment terms. We face a number of risks due to our dependence on contract manufacturers, including:

•reduced control over delivery schedules, particularly for international contract manufacturing sites;

•reliance on the quality assurance procedures of third parties;

•potential uncertainty regarding manufacturing yields and costs;

•potential lack of adequate capacity during periods of high demand or inability to fulfill manufacturing orders due to supply issues;

•potential variability of pricing or payment terms due to agreement length;

•risks and uncertainties associated with the locations or countries where our products are manufactured, including potential manufacturing disruptions caused by geopolitical events, military actions, work stoppages or other social factors, natural disasters or other environmental factors, or international health emergencies, such as the COVID-19 pandemic;

•counterparty risk, particularly if our contract manufacturers are sensitive to inflation and interest-rate risk;

•limited warranties on components; and

•potential misappropriation of our intellectual property.

Any of these risks could impair our ability to fulfill orders. Our products are built with and incorporate increasingly sophisticated technology and any delays by our contract manufacturers or their inability to meet our product specifications or quality standards may cause us to be unable to meet the delivery requirements of our customers, which could decrease customer satisfaction and harm our product sales. In addition, if our contract manufacturers are unable or unwilling to continue manufacturing our products or components of our products in required volumes or our relationship with any of our contract manufacturers is discontinued for any reason, we would be required to identify and qualify alternative manufacturers, which could cause us to be unable to meet

our supply requirements to our customers and result in the breach of our customer agreements. Qualifying a new contract manufacturer and commencing volume production is expensive and time-consuming. If we are required to change or qualify a new contract manufacturer, we could lose revenue and damage our customer relationships.

We rely on various third-party service partners to help complement our global operations, and failure to adequately manage these relationships could adversely impact our financial results and relationships with customers.

We rely on a number of third-party service partners, both domestic and international, to complement our global operations. We rely upon these partners for certain installation, maintenance, logistics and support functions. In addition, as our customers increasingly seek to rely on vendors to perform additional services relating to the design, construction and operation of their networks, the scope of work performed by our service partners is likely to increase and may include areas where we have less experience providing or managing such services. We must successfully identify, assess, train and certify qualified service partners in order to ensure the proper installation, deployment and maintenance of our products. The vetting and certification of these partners can be costly and time-consuming, and certain partners may not have the same operational history, financial resources and scale as we have. Additionally, certain service partners may provide similar services for other companies, including our competitors. We may not be able to manage our relationships with our service partners effectively, and we cannot be certain that they will be able to deliver services in the manner or time required, that we will be able to maintain the continuity of their services, or that they will adhere to our approach to ethical business practices. We may also be exposed to a number of risks or challenges relating to the performance of our service partners, including:

•delays in recognizing revenue;

•liability for injuries to persons, damage to property or other claims relating to the actions or omissions of our service partners;

•our services revenue and gross margin may be adversely affected; and

•our relationships with customers could suffer.

If we do not effectively manage our relationships with third-party service partners, or if they fail to perform these services in the manner or time required, our financial results and relationships with our customers could be adversely affected.

We must respond to rapid technological change and comply with evolving industry standards and requirements for our products to be successful.

The optical transport networking equipment market is characterized by rapid technological change, changes in customer requirements and evolving industry standards. We continually invest in research and development to sustain or enhance our existing products, but the introduction of new communications technologies and the emergence of new industry standards or requirements could render our products obsolete. Further, in developing our products, we have made, and will continue to make, assumptions with respect to which standards or requirements will be adopted by our customers and competitors. If the standards or requirements adopted by our prospective customers are different from those on which we have focused our efforts, market acceptance of our products would be reduced or delayed, and our business would be harmed. We are continuing to invest a significant portion of our research and development efforts in the development of our next-generation products. We expect our competitors will continue to improve the performance of their existing products and introduce new products and technologies and to influence customers’ buying criteria so as to emphasize product capabilities that we do not, or may not, possess. To be competitive, we must anticipate future customer requirements and continue to invest significant resources in research and development, sales and marketing, and customer support, and the investment demands may increase as the technology becomes more complex. If we do not anticipate these future customer requirements and invest in the technologies necessary to enable us to have and to sell the appropriate solutions, it may limit our competitive position and future sales, which would have an adverse effect on our business and financial condition. We may not have sufficient resources to make these investments and we may not be able to make the technological advances necessary to be competitive.

If we fail to accurately forecast our manufacturing requirements or customer demand, we could incur additional costs, including inventory write-downs or equipment write-offs, which would adversely affect our business and results of operations.

We generate forecasts of future demand for our products several months prior to the scheduled delivery to our prospective customers. This requires us to make significant investments before we know if corresponding revenue will be recognized. Lead times vary significantly for materials and components, including ASICs, that we need to order for the manufacture of our products and depend on factors such as the specific supplier, contract terms and demand for each component at a given time. In the past, we have experienced lengthened lead times for certain components, and we continue to see long lead times for certain components due to industry-wide supply chain challenges, which makes forecasting more challenging. We may be required to purchase increased levels of such components to satisfy our delivery commitments to our customers as a result of longer lead times for components. In addition, we must manage our inventory to ensure we continue to meet our commitments as we introduce new products or make enhancements to our existing products.

If we overestimate market demand for our products and, as a result, increase our inventory in anticipation of customer orders that do not materialize, we will have excess inventory, which could result in increased risk of obsolescence and significant inventory write-downs. Furthermore, this will result in reduced production volumes and our fixed costs will be spread across fewer units, increasing our per unit costs. If we underestimate demand for our products, we will have inadequate inventory, which could slow down or interrupt the manufacturing of our products, cause delays in shipments and our ability to recognize revenue, and result in potential loss of customers to competitors. In addition, we may be unable to meet our supply commitments to customers, which could result in a loss of certain customer opportunities or a breach of our customer agreements.

Our large customers have substantial negotiating leverage, which may cause us to agree to terms and conditions that result in lower average selling prices and potentially increased cost of sales leading to lower gross margin, each of which would harm our results of operations.

Many of our customers are large service providers and ICPs that have substantial purchasing power and leverage in negotiating contractual arrangements with us. In addition, customer consolidation in the past few years has created combined companies that are even larger and have greater negotiating leverage. Our customers have sought and may continue to seek advantageous pricing, payment and other commercial terms. This may further impact our profitability if we are unable to recover through price increases passed along to these customers additional costs we have incurred from inflationary pressures to the supply chain or shipping and freight. We have also occasionally agreed and may continue to agree to unfavorable commercial terms with these customers, including the potential of reducing the average selling price of our products, increasing cost of sales or agreeing to extended payment terms in response to these commercial requirements or competitive pricing pressures. Continued inflation could decrease the profitability of customer contracts, particularly those with extended payment terms, that are not indexed to inflation. If we are compelled to agree to disadvantageous terms and conditions, unable to comply with such terms and conditions, or adapt our business model and operations to such terms and conditions, then our operating results will be negatively impacted.

Our sales cycle can be long and unpredictable, which could result in an unexpected revenue shortfall in any given quarter.

Our products can have a lengthy sales cycle, which can extend from six to twelve months and may take even longer for larger prospective customers. Our prospective customers conduct significant evaluation, testing, implementation and acceptance procedures before they purchase our products. We incur substantial sales and marketing expenses and expend significant management effort during this time, regardless of whether we make a sale. Supply chain disruptions have also at times lengthened, and may in the future lengthen, our sales cycle due to delays in the customer certification process for our products.

Because our sales cycle is long, we are likely to recognize higher inflation-related costs before recognizing the benefits of any price increases that we implement for our products. Moreover, the costs associated with our sales cycle may increase faster than our ability to increase prices. In addition, changes in regulatory requirements or uncertainty associated with the regulatory environment could delay or impede

investment in network infrastructures and adversely affect our business, financial condition and results of operations.

Because the purchase of our equipment involves substantial cost, most of our customers wait to purchase our equipment until they are ready to deploy it in their network. As a result, it is difficult for us to accurately predict the timing of future purchases by our customers. In addition, product purchases are often subject to budget constraints, multiple approvals and unplanned administrative processing and other delays, including the need for the customer to obtain external financing. If sales expected from customers for a particular quarter are not realized in that quarter or at all, our revenue will be negatively impacted.

Any acquisitions or strategic transactions that we undertake could disrupt our business and harm our financial condition and results of operations.

We have made strategic acquisitions of businesses, technologies and other assets in the past, including most recently the Acquisition. We may engage in acquisitions, divestitures or other strategic transactions in the future. In order to undertake certain of these transactions, we may use cash, issue equity that could dilute our current stockholders, or incur debt or assume indebtedness. If we are unable to achieve the anticipated efficiencies and strategic benefits of such transactions, it could adversely affect our business, financial condition and results of operations. In addition, the market price of our common stock could be adversely affected if investors and securities analysts react unfavorably to a strategic transaction or if the integration or the anticipated financial and strategic benefits of such transactions are not realized as rapidly as or to the extent anticipated by investors and securities analysts.

Acquisitions, divestitures or other strategic transactions can also result in adverse tax consequences, warranty or product liability exposure related to acquired assets, additional stock-based compensation expense, and write-up of acquired inventory to fair value. Divestitures can also result in contractual, employment or intellectual property liability related to divested assets. In addition, we may record goodwill and other purchased intangible assets in connection with an acquisition and incur impairment charges in the future. If our actual results, or the plans and estimates used in future impairment analyses, are less favorable than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges.

Acquisitions, divestitures or other strategic transactions also involve numerous risks that could disrupt our ongoing business and distract our management team, including:

•problems integrating the acquired operations, technologies or products with our own;

•challenges in divesting assets and intellectual property without negatively affecting our retained business;

•diversion of management’s attention from our core business;

•adverse effects on existing business relationships with suppliers and customers;

•risks associated with entering new markets or exiting existing markets; and

•loss of key employees.

Our failure to adequately manage the risks associated with an acquisition, divestment or strategic transaction could have an adverse effect on our business, financial condition and results of operations.

Actions that we are taking or may in the future take to restructure our business to cut costs and align our operating structure with current or future opportunities may not be as effective as anticipated and may have negative consequences.

We have incurred, and may in the future incur, substantial costs in connection with restructuring plans. Although these restructuring initiatives may be taken to improve our operating efficiency and to reallocate resources to align more closely with our evolving business model and current and future opportunities, they may not result in the benefits we anticipate. We incur substantial costs to implement restructuring plans, and our restructuring activities may subject us to reputational and litigation risks. Our past restructuring plans do not provide any assurance that we will realize anticipated cost savings or other benefits from any restructuring plans

we implement. In addition, restructuring plans may have other consequences, such as attrition beyond any planned reductions in workforce, a negative effect on employee morale and productivity or our ability to attract highly skilled employees. Restructuring presents other significant potential risks such as the actual or perceived disruption of service or reduction in service standards to customers, loss of sales, the failure to preserve supplier relationships and diversion of management attention. In addition, as a result of these restructuring actions, our ability to execute on product development, address key market opportunities or meet customer demand could be materially and adversely affected. Further, any anticipated benefits from these restructuring initiatives may be realized later than expected or not at all, and the ongoing costs of implementing these measures may be greater than anticipated. As a result, current or future restructuring plans may affect our revenue and other operating results.

Financial and Macroeconomic Risk Factors

We may be unable to generate the cash flow necessary to make anticipated capital expenditures, service our debt or grow our business.

We may not be able to generate sufficient cash flow from operations to make anticipated capital expenditures, service our debt or grow our business. Our ability to pay our expenses, service our debt and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, competitive, legislative, political, regulatory, public health issues and other factors beyond our control, and our ability to continue to realize synergies and anticipated cost savings. If we are unable to generate sufficient cash flow from operations to service our debt or to make anticipated capital expenditures, we may be required to sell assets, reduce capital expenditures, borrow additional funds or evaluate alternatives for efficiently funding our capital expenditures and ongoing operations, including the issuance of equity, equity-linked and debt securities.

Inflation may adversely affect us by increasing costs beyond what we can recover through price increases.

Inflation, which has continued in the U.S. and globally, can adversely affect us by increasing the costs of labor, supplies and other costs of doing business, and price increases within our supply chain have negatively affected our gross margin. In an inflationary environment, our ability to raise prices or add additional cost-recovery surcharges of a magnitude sufficient to match the rate of inflation, on a timely basis, may be constrained by customer resistance and competitive concerns, as well as industry-specific and other economic conditions, which would reduce our profit margins. Moreover, even if we seek to implement price increases in response to inflationary pressures, because of our long sales cycle, we may recognize increased costs as a result of inflation before we are able to recognize the benefits of any such price increases. We have experienced increases in the prices of labor, supplies and other costs of doing business and continued inflationary pressures could continue to adversely impact our profitability.

Unfavorable macroeconomic and market conditions may adversely affect our industry, business and financial results.

In the past, unfavorable macroeconomic and market conditions have resulted in sustained periods of decreased demand for optical communications products and slowdowns in the telecommunications industry in which we operate. Such slowdowns may result in:

•reduced demand for our products as a result of constraints on capital spending by our customers;

•increased price competition for our products, not only from our competitors, but also as a result of the utilization of inventoried or underutilized products by our customers or potential customers, which could put additional downward pressure on our near-term gross profits;

•risk of excess or obsolete inventories;

•our customers facing financial difficulties, including bankruptcy;

•excess manufacturing capacity and higher associated overhead costs as a percentage of revenue; and

•more limited ability to accurately forecast our business and future financial performance.

The COVID-19 pandemic created significant uncertainty in global macroeconomic conditions and capital markets, credit markets, and, in particular, supply chains continue to experience high levels of disruption, volatility and uncertainty. High inflation, along with other signs of economic disruption, has also contributed to adverse global macroeconomic conditions. These conditions may also result in the tightening of credit markets, which could limit or delay our customers’ ability to obtain necessary financing for their purchases of our products.

Our customers may delay or cancel their purchases or increase the time they take to pay or default on their payment obligations due to a lack of liquidity in the capital markets, the continued uncertainty in the global economic environment or inflationary concerns, which could result in a higher level of bad debt expense and would negatively affect our business and operating results. In addition, currency fluctuations could negatively affect our international customers’ ability or desire to purchase our products.

A lack of liquidity and economic uncertainty may also adversely affect our suppliers or the terms on which we purchase products from these suppliers. These impacts could limit our ability to obtain components for our products from these suppliers and could adversely impact our supply chain or the delivery schedule to our customers. Suppliers could also require us to purchase more expensive components, or re-design our products, which could cause increases in the cost of our products and delays in the manufacturing and delivery of our products. Such events could harm our gross margin and harm our reputation and our customer relationships, either of which could harm our business and operating results.

If we need additional capital in the future, it may not be available to us on favorable terms, or at all.

Our business requires significant capital. We have historically relied on outside debt or equity financing as well as cash flow from operations to fund our operations, capital expenditures and expansion. For example, in September 2018, we issued convertible senior notes due September 1, 2024 (the “2024 Notes”) to pay the cost of the Capped Calls, as discussed below, to fund the cash portion of the purchase price of the Acquisition, and for general corporate purposes. In August 2019 and as amended thereafter, we entered into the Prior Credit Agreement to provide additional working capital flexibility to manage our business. In addition, in March 2020, we issued convertible senior notes due March 1, 2027 (the “2027 Notes”) to raise additional funds for general corporate purposes, including working capital to fund growth and potential strategic projects. On August 12, 2020, we entered into an Open Market Sales Agreement with Jefferies LLC ("Jefferies") under which we issued and sold through Jefferies, acting as agent or principal, shares of our common stock having an aggregate offering price of $96.3 million, to raise funds for general corporate purposes, including working capital and capital expenditures. In June 2022, we terminated the Prior Credit Agreement and entered into the Loan Agreement to repay existing debt (including amounts outstanding under the Prior Credit Agreement) and for working capital and general corporate purposes, including to fund growth. In August 2022, we issued convertible senior notes due August 1, 2028 (the “2028 Notes” and, together with the 2024 Notes and the 2027 Notes, the “convertible senior notes”) to repurchase a portion of the 2024 Notes, for general corporate purposes, including working capital and to fund growth and potential strategic projects. We may require additional capital from equity or equity-linked financing, debt financing or other financings in the future to fund our operations, respond to competitive pressures or strategic opportunities or to refinance our existing debt obligations. In the event that we require additional capital, we may not be able to secure timely additional financing, or restructure existing debt, on favorable terms, or at all, and may be affected by the impacts on capital markets of global economic uncertainty and inflationary pressures. The terms of any additional financings or restructurings may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer dilution in their percentage ownership of our company, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, if and when we require it, our ability to grow or support our business and to respond to business challenges could be limited and our business will be harmed.

Our Loan Agreement and any other credit or similar agreements into which we may enter in the future may restrict our operations, particularly our ability to respond to changes or to take certain actions regarding our business.

Our Loan Agreement contains a number of restrictive covenants that may impose operating and financial restrictions on us and limit our ability to engage in acts that may be in our long-term interest, including restrictions on our ability to incur debt, create liens and encumbrances, engage in certain fundamental changes, dispose of assets, prepay certain indebtedness, make restricted payments, make investments, and engage in

transactions with affiliates, in each case subject to limitations and exceptions set forth in the Loan Agreement. The Loan Agreement also contains a financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio.

The Loan Agreement also contains customary events of default, such as the failure to pay obligations when due, a material breach of representations and warranties or covenants, the entry of material judgments against certain of our subsidiaries, the initiation of bankruptcy or insolvency proceedings of certain of our subsidiaries, defaults on certain other indebtedness, a change of control, the failure of the guaranty of certain of our subsidiaries to be in effect or the failure of the security documents to create valid and perfected liens or the loan documents to be valid and enforceable, which could have a material adverse effect on our business, operations, and financial results. Upon an event of default, the lenders may, subject to customary cure rights, require the immediate payment of all amounts outstanding and foreclose on collateral, which could force us into bankruptcy or liquidation. In the event that our lenders accelerated the repayment of the borrowings, we may not have sufficient assets to repay that indebtedness. Any acceleration of amounts due under the Loan Agreement would likely have a material adverse effect on us. As a result of these restrictions, we may be limited in how we conduct business, unable to raise additional debt or equity financing to operate during general economic or business downturns, or unable to compete effectively or to take advantage of new business opportunities.

In addition, we may enter into other credit agreements or other debt arrangements from time to time which contain similar or more extensive restrictive covenants and events of default, in which case we may face similar or additional limitations as a result of the terms of those credit agreements or other debt arrangements.

Our debt obligations may adversely affect our ability to raise additional capital and will be a burden on our future cash resources, particularly if we elect to settle these obligations in cash upon conversion or upon maturity or required repurchase.

As of December 31, 2022, the outstanding aggregate principal amount of the 2024 Notes, the 2027 Notes and the 2028 Notes was $102.7 million, $200.0 million and $373.8 million, respectively. The degree to which we are leveraged could have important consequences, including, but not limited to, the following:

•our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, litigation, general corporate or other purposes may be limited; and

•a substantial portion of our future cash balance may be dedicated to the payment of the principal of our indebtedness as we have stated the intention to pay the principal amount of each series of convertible senior notes in cash upon conversion or when otherwise due, such that we would not have those funds available for use in our business.

Our ability to meet our payment obligations under our debt instruments, including the convertible senior notes, depends on our future cash flow performance. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors, as well as other factors that may be beyond our control. There can be no assurance that our business will generate positive cash flow from operations, or that additional capital will be available to us, in an amount sufficient to enable us to meet our debt payment obligations and to fund other liquidity needs. If we are unable to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may be unable to meet our debt payment obligations. As a result, we may be more vulnerable to economic downturns, less able to withstand competitive pressures and less flexible in responding to changing business and economic conditions.

Our international sales and operations subject us to additional risks that may harm our operating results.

Sales of our products into international markets continue to be an important part of our business. During 2022, 2021 and 2020, we derived approximately 45%, 53% and 54%, respectively, of our revenue from customers outside of the United States. We expect that significant management attention and financial resources will be required for our international activities over the foreseeable future as we continue to operate in international markets. In some countries, our success in selling our products and growing revenue will depend in part on our ability to form relationships with local partners. Our inability to identify appropriate partners or reach mutually satisfactory arrangements for international sales of our products could impact our ability to maintain or

increase international market demand for our products. In addition, many of the companies we compete against internationally have greater name recognition and a more substantial sales and marketing presence.

We have sales and support personnel in the Americas, EMEA (with offices in the Middle East) and APAC (including China). In addition, we have established development centers in Canada, China, Finland, Germany, India, Portugal and Sweden. There is no assurance that our reliance upon development resources in international locations will enable us to achieve meaningful cost reductions or greater resource efficiency. We are also aggressively pursuing opportunities with customers in additional geographies, including EMEA, APAC and Latin America. Our efforts to increase our sales and capture market share in international markets may ultimately be unsuccessful and may limit our growth and adversely impact our business, financial condition and results of operations.

New or continuing disruptions of the global supply chain or the manufacture of our customer’s components caused by events outside of our control could impact our results of operations by impairing our ability to timely and efficiently deliver our products or provide installation and maintenance services to our customers.

In addition, our operations in Russia have been impacted by sanctions and other trade controls imposed by the United States and other governments in response to Russia's military operations in Ukraine which started in February 2022. The imposition of these sanctions and controls have prevented us from performing existing contracts. For the year ended December 31, 2022, less than 1% of our revenue was derived from customers in Russia, and for the year ended December 25, 2021, approximately 1% of our revenue was derived from customers based in Russia. A de minimis percentage of our revenue is derived from Russian customers including channel partners and customers in other countries whose contracts with us may involve Russian entities.

Our international operations are subject to inherent risks, and our future results could be adversely affected by a variety of factors, many of which are outside of our control, including:

•greater difficulty in collecting accounts receivable and longer collection periods;

•difficulties of managing and staffing international offices, and the increased travel, infrastructure and legal compliance costs associated with multiple international locations;

•political, social and economic instability, including wars, terrorism, political unrest, boycotts, curtailment of trade and other business restrictions;

•tariff and trade barriers and other regulatory requirements, contractual limitations, or customer specifications impacting our ability to sell or develop our products in certain foreign markets;

•less effective protection of intellectual property than is afforded to us in the United States or other developed countries;

•potentially adverse tax consequences;

•natural disasters, acts of war or terrorism, and health crises, including the COVID-19 pandemic;

•changes to free trade agreements, trade protection measures, tariffs, export compliance, domestic preference procurement requirements, qualification to transact business and additional regulatory requirements, including changes related to policy and other changes made by the federal government in the United States, other national governments or multinational bodies; and

•effects of changes in currency exchange rates, particularly relative increases in the exchange rate of the U.S. dollar compared to other currencies that could negatively affect our financial results and cash flows.

The concentration of the storage and distribution of our inventory primarily in one location in southeastern Asia increases the risks of our global operations. As a result, our operations are susceptible to local and regional factors in that area, such as accidents, system failures and weather conditions, natural disasters (including floods and earthquakes and related fires), and other unforeseen events and circumstances. Any significant interruption in the operations or availability of the storage and distribution facilities in which our

inventory is held could lead to logistical and fulfillment issues or increased costs, which could have a material adverse effect on our results of operations, financial condition and cash flows.

International customers may also require that we comply with certain testing or customization of our products to conform to local standards. The product development costs to test or customize our products could be extensive and a material expense for us.

Our international operations are also subject to increasingly complex foreign and U.S. laws and regulations, including, but not limited to, anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act of 1977, as amended (the "FCPA"), and the United Kingdom Bribery Act 2010, as amended (the “UK Bribery Act”), antitrust or competition laws, anti-money laundering laws, various trade controls, national security related regulations, and data privacy laws, among others. Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our reputation, our international expansion efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies, procedures and training designed to ensure compliance with these laws and regulations, there can be no complete assurance that any individual employee, contractor or agent will not violate our policies. Additionally, the costs of complying with these laws (including the costs of investigations, auditing and monitoring) could also adversely affect our current or future business.

As we continue to expand our business globally, our success will depend, in large part, on our ability to effectively anticipate and manage these and other risks and expenses associated with our international operations. Our failure to manage any of these risks successfully could harm our international operations and reduce our international sales, adversely affecting our business, financial condition and results of operations.

We may be adversely affected by fluctuations in currency exchange rates.

A portion of our sales and expenses stem from countries outside of the United States, and are in currencies other than U.S. dollars, and therefore subject to foreign currency fluctuation. Accordingly, fluctuations in foreign currency rates could have a material impact on our financial results in future periods. We have from time to time entered into foreign currency exchange forward contracts to reduce the impact of foreign currency fluctuations on certain non-functional currency account balances. Even if we have forward contracts in place, while they may reduce some of the impact of currency exchange rate movements on certain transactions, they would not cover all foreign-denominated transactions and therefore may not entirely eliminate the impact of fluctuations in exchange rates on our results of operations and financial condition.

Our effective tax rate may increase or fluctuate, which could increase our income tax expense and reduce our net income.

Our effective tax rate can be adversely affected by several factors, many of which are outside of our control, including:

•changes in the valuation of our deferred tax assets and liabilities, and in deferred tax valuation allowances;

•changes in the relative proportions of revenue and income before taxes in the various jurisdictions in which we operate that have differing statutory tax rates;

•changing tax laws, regulations, rates and interpretations in multiple jurisdictions in which we operate;

•changes to the financial accounting rules for income taxes;

•the tax effects of acquisitions; and

•the resolution of issues arising from tax audits.

The United States recently enacted the Inflation Reduction Act of 2022, which, among other changes, implements a 1% excise tax on certain stock buybacks, which would generally apply to repurchases of stock by U.S. corporations, including certain transactions with the Capped Calls. Many countries and organizations such

as the Organization for Economic Cooperation and Development are actively considering changes to existing tax laws or have proposed or enacted new laws, including an agreement to implement a 15% global minimum tax, that could increase our tax obligations in countries where we do business or cause us to change the way we operate our business. The Council of the European Union has adopted this initiative for enactment by European Union member states by December 31, 2022, with implementation into the domestic laws of those states by the end of 2023. Any changes in U.S. federal, state or international tax laws or tax rulings could adversely affect our effective tax rate and our results of operations.

Beginning January 1, 2022, the Tax Cuts and Jobs Act of 2017 eliminated the right to deduct research and development expenditures for tax purposes in the period the expenses were incurred and instead requires all U.S. and foreign research and development expenditures to be amortized over five and fifteen tax years, respectively. This provision may materially increase our effective tax rate and reduce our operating cash flows over time as we continue to utilize available net operating losses and tax credits.

We may issue additional shares of our common stock in connection with conversions of the 2024 Notes, the 2027 Notes or the 2028 Notes, and thereby dilute our existing stockholders and potentially adversely affect the market price of our common stock.

In the event that some or all of each series of convertible senior notes are converted and we elect to deliver shares of common stock to the extent permitted, the ownership interests of existing stockholders will be diluted, and any sales in the public market of any shares of our common stock issuable upon such conversion could adversely affect the prevailing market price of our common stock. In addition, the anticipated conversion of any series of convertible senior notes we have issued could depress the market price of our common stock.

The fundamental change provisions of the 2024 Notes, the 2027 Notes and the 2028 Notes may delay or prevent an otherwise beneficial takeover attempt of us.

If a fundamental change, such as an acquisition of our company, occurs prior to the maturity of the 2024 Notes, the 2027 Notes or the 2028 Notes, holders of the applicable series of convertible senior notes will have the right, at their option, to require us to repurchase all or a portion of their convertible senior notes of such series. In addition, if such fundamental change also constitutes a make-whole fundamental change, the conversion rate for the applicable series of convertible senior notes may be increased upon conversion of the such series of convertible senior notes in connection with such make-whole fundamental change. Any increase in the conversion rate will be determined based on the date on which the make-whole fundamental change occurs or becomes effective and the price paid (or deemed paid) per share of our common stock in such transaction. Any such increase will be dilutive to our existing stockholders. Our obligation to repurchase any series of convertible senior notes or increase the conversion rate upon the occurrence of a make-whole fundamental change may, in certain circumstances, delay or prevent a takeover of us that might otherwise be beneficial to our stockholders.

The Capped Calls may affect the value of the 2024 Notes and our common stock.

In connection with the issuance of the 2024 Notes, we entered into capped call transactions (the "Capped Calls") with certain financial institutions who are the option counterparties. The Capped Calls are expected generally to reduce or offset the potential dilution upon conversion of the 2024 Notes or offset any cash payments we are required to make in excess of the principal amount of converted 2024 Notes, as the case may be, with such reduction or offset subject to a cap.

From time to time, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the 2024 Notes. This activity could also cause an increase or a decrease in the market price of our common stock.

We are subject to counterparty risk with respect to the Capped Calls.

The option counterparties to the Capped Calls are financial institutions, and we will be subject to the risk that any or all of them might default under the Capped Calls. Our exposure to the credit risk of the counterparties will not be secured by any collateral. Past global economic conditions have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our

exposure at the time under the Capped Calls with such option counterparty. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price and in the volatility of our common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We can provide no assurance as to the financial stability or viability of the option counterparties.

Legal and Regulatory Risk Factors

If we fail to protect our intellectual property rights, our competitive position could be harmed, or we could incur significant expense to enforce our rights.

We depend on our ability to protect our proprietary technology. We rely on a combination of methods to protect our intellectual property, including limiting access to certain information, and utilizing trade secret, patent, copyright and trademark laws and confidentiality agreements with employees and third parties, all of which offer only limited protection. The steps we have taken to protect our proprietary rights may be inadequate to preclude misappropriation or unauthorized disclosure of our proprietary information or infringement of our intellectual property rights, and our ability to police such misappropriation, unauthorized disclosure or infringement is uncertain, particularly in countries outside of the United States. This is likely to become an increasingly important issue if we expand our operations and product development into countries that provide a lower level of intellectual property protection. We do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims, and even if patents are issued, they may be contested, circumvented or invalidated. Moreover, the rights granted under any issued patents may not provide us with a competitive advantage, and, as with any technology, competitors may be able to develop similar or superior technologies to our own now or in the future.

Protecting against the unauthorized use of our products, trademarks and other proprietary rights is expensive, difficult, time consuming and, in some cases, impossible. Litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity or scope of the proprietary rights of others. Such litigation could result in substantial cost and diversion of management resources, either of which could harm our business, financial condition and results of operations. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than we do. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property.

Claims by others that we infringe on their intellectual property rights could harm our business.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, many leading companies in the optical transport networking industry, including our competitors, have extensive patent portfolios with respect to optical transport networking technology. In addition, non-practicing patent holding companies seek to monetize patents they have purchased or otherwise obtained. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps in technology implementation occur. From time to time, third parties may assert exclusive patent, copyright, trademark and other intellectual property rights to technologies and related standards that are important to our business or seek to invalidate the proprietary rights that we hold. Competitors or other third parties have asserted, and may continue to assert, claims or initiate litigation or other proceedings against us or our manufacturers, suppliers or customers alleging infringement of their proprietary rights, or seeking to invalidate our proprietary rights, with respect to our products and technology. In addition, in the past we have had certain patent licenses with third parties that have not been renewed, and if we cannot successfully renew these licenses, we could face claims of infringement. In the event that we are unsuccessful in defending against any such claims, or any resulting lawsuits or proceedings, we could incur liability for damages or have valuable proprietary rights invalidated. For additional information regarding certain of the legal proceedings in which we are involved, see Part II, Item 8, Note 13 under the heading “Legal Matters.”

Any claim of infringement from a third party, even one without merit, could cause us to incur substantial costs defending against the claim, and could distract our management from running our business. Furthermore, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages or could include an injunction or other court order that could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual property, which may not be available on

commercially reasonable terms or at all. Alternatively, we may be required to develop non-infringing technology, which would require significant effort and expense and may ultimately not be successful. Any of these events could harm our business, financial condition and results of operations.

Competitors and other third parties have and may continue to assert infringement claims against our customers and sales partners. Any of these claims may require us to initiate or defend potentially protracted and costly litigation on their behalf, regardless of the merits of these claims, because we generally indemnify our customers and sales partners from claims of infringement of proprietary rights of third parties. If any of these claims succeed, we may be forced to pay damages on behalf of our customers or sales partners, which could have an adverse effect on our business, financial condition and results of operations.

We also incorporate free and open source licensed software into our products. Although we monitor our use of such open source software closely, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In addition, non-compliance with open source software license terms and conditions could subject us to potential liability, including intellectual property infringement or contract claims. In such events, we may be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished in a timely manner, any of which could adversely affect our business, financial condition and results of operations.

Security incidents, such as data breaches and cyber-attacks, could compromise our intellectual property and proprietary or confidential information and cause significant damage to our business and reputation.

In the ordinary course of our business, we maintain sensitive data on our networks and systems, including data related to our intellectual property and data related to our business, customers and business partners, which may be considered proprietary or confidential information. This sensitive data includes certain personal information and other data relating to our employees and others. We also utilize third-party service providers to host, transmit, or otherwise process data in connection with our business activities, including our supply chain processes, operations, and communications. Companies, especially in the technology industry, have been increasingly subject to a wide variety of security incidents, cyber-attacks, malicious activity, including ransomware, malware and viruses, and other attempts to gain unauthorized access and disrupt systems and the confidentiality, security, and integrity of information, and we and our third-party service providers and suppliers have faced and may continue to face security threats and attacks from a variety of sources. In accordance with our flexible approach to work arrangements, many of our employees are working from home and accessing our corporate network via remote devices, which may be less secure than those used in our offices and thus could increase the potential for such events to occur.

While the secure maintenance of this information and the security of the systems used in our business are critical to our business and reputation, our network and storage applications, and those systems and other business applications maintained by our third-party providers, may be subject to unauthorized access by hackers or breached or otherwise compromised due to operator error, malfeasance or other system disruptions. It may be difficult to anticipate or immediately detect such security incidents or breaches and to prevent or mitigate damage caused as a result. Accordingly, a data breach, security incident, cyber-attack, attack using ransomware or other malware, or any other unauthorized access to systems used in our business or unauthorized acquisition, disclosure, or other processing of our information or other information that we or our third-party vendors maintain or otherwise process could compromise our intellectual property, disrupt our operations, or result in loss of or unauthorized access to or acquisition, disclosure, modification, misuse, corruption, unavailability, or destruction of proprietary or confidential information. While we work to safeguard our internal networks and systems and validate the security of our third-party suppliers and providers to mitigate these potential risks, including through information security policies and employee awareness and training, there is no assurance that such actions will be sufficient to prevent cyber-attacks or security breaches or incidents, and we cannot guarantee that our systems and networks or our third-party service providers’ systems and networks have not been breached or that they or any components of our supply chain do not contain exploitable defects or bugs, including defects or bugs that could result in a breach of or disruption to our systems and networks or the systems and networks of third parties that support our operations. We and third-party service providers also may face difficulties or delays in identifying or responding to security breaches and other security-related incidents. We have been subjected in the past to a range of incidents including phishing, emails purporting to come from an executive or vendor seeking payment requests, malware and communications from look-alike corporate domains. For example, in

2021, we experienced a phishing attack that resulted in an immaterial loss. While they have not had a material effect on our business or our network security to date, security breaches or incidents involving access to or improper use of our systems, networks or products, or those of third-party service providers, could compromise confidential or otherwise protected information, result in unauthorized acquisition, disclosure, modification, misuse, corruption, unavailability, or destruction of data, cause payments to be diverted to fraudulent accounts, or otherwise disrupt our operations. Security breaches or incidents, or any reports or perceptions that they have occurred, could cause us to incur significant costs and expenses to remediate and otherwise respond to any actual or suspected breach or incident, subject us to regulatory actions and investigations, disrupt key business operations, result in claims, demands, and liability, and divert attention of management and key information technology resources, any of which could cause significant harm to our business and reputation. Even the perception of inadequate security may damage our reputation and negatively impact our business. Further, we could be required to expend significant capital and other resources to address any security incident or breach and to attempt to prevent future security incidents and breaches.

Although we maintain insurance coverage that may cover certain liabilities in connection with some security breaches and other security incidents, we cannot be certain our insurance coverage will be adequate for liabilities actually incurred, including any consequential damages that may arise from such security incidents, that insurance will continue to be available to us on commercially reasonable terms (if at all) or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, or denials of coverage could have a material adverse effect on our business, including our financial condition, results of operations and reputation.

If we fail to maintain effective internal controls over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

We are required to comply with Section 404 of the Sarbanes-Oxley Act of 2002 ("SOX"). The provisions of SOX require, among other things, that we maintain effective internal controls over financial reporting and disclosure controls and procedures. Preparing our financial statements involves a number of complex processes, many of which are done manually and are dependent upon individual data input or review. These processes include, but are not limited to, calculating revenue, deferred revenue and inventory costs. While we continue to automate our processes and put in place controls to reduce the likelihood for errors, we expect that for the foreseeable future many of our processes will remain manually intensive and thus subject to human error. If we are unable to implement effective key operational controls around financial processes and successfully manage and monitor manual processes, we may fail to prevent or detect material misstatements in our financial statements, in which case investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our securities may decline.

We are subject to various governmental export control, trade sanctions, and import laws and regulations that could impair our ability to compete in international markets or subject us to liability if we violate these controls.

In some cases, our products are subject to U.S. and foreign export control laws and regulations that may limit where and to whom we are permitted to sell our products, including the Export Administration Regulations administered by the U.S. Department of Commerce, and our activities may be subject to trade and economic sanctions, including those administered by the United States Department of the Treasury’s Office of Foreign Assets Control (collectively, “Trade Controls”). As such, a license may be required to export or re-export our products, or provide related services, to certain countries and end-users, and for certain end-uses. Further, our products incorporating encryption functionality may be subject to special controls applying to encryption items or certain reporting requirements.

We have procedures in place designed to ensure our compliance with Trade Controls, with which failure to comply could subject us to both civil and criminal penalties, including substantial fines, possible incarceration of responsible individuals for willful violations, possible loss of our export or import privileges, or reputational harm. Further, the process for obtaining necessary licenses may be time-consuming or unsuccessful, potentially causing delays in sales or losses of sales opportunities. Trade Controls are complex and dynamic regimes, and monitoring and ensuring compliance can be challenging, particularly given that our products are widely distributed throughout the world. Although we have no knowledge that our activities have resulted in material violations of Trade Controls, any failure by us or our partners to comply with applicable laws and regulations

would have negative consequences for us, including reputational harm, government investigations, and penalties.

In addition, various countries regulate the import of certain technologies and have enacted laws that could limit our ability to distribute our products and certain product features or could limit our customers’ ability to implement our products in those countries. Changes in our products or changes in U.S. and foreign import and export regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the import and export of our products to certain countries altogether. For example, the United States has imposed tariffs on a large variety of products originating from China, including some on components that are supplied to us from China. Depending upon the duration and implementation of these and future tariffs, as well as our ability to mitigate their impact, these tariffs could materially affect our business, including in the form of increased cost of goods sold, increased pricing for customers, and reduced sales. Additionally, the U.S. government has levied controls affecting the ability to send certain products and technology related to semiconductors, semiconductor manufacturing and supercomputing to China without an export license and adding additional entities to restricted party lists. It remains unclear what additional actions, if any, will be taken by the governments of the United States or China with respect to such trade and tariff matters. Any change in import and export regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or technologies impacted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. Failure to comply with these and similar laws on a timely basis, or at all, or any limitation on our ability to develop, export or sell our products would adversely affect our business, financial condition and results of operations.

We are subject to environmental regulations that could adversely affect our business.

We are subject to complex U.S. and foreign environmental rules and regulations or other social initiatives that impact how and where we manufacture our products. In particular, our manufacturing operations use substances that are regulated by various federal, state, local, foreign and international laws and regulations governing health, safety and the environment, including U.S. Environmental Protection Agency regulations and WEEE, RoHS and REACH regulations adopted by the E.U. From time to time, the E.U. restricts or considers restricting certain substances under these directives. For example, InP has been considered for restriction under RoHS. Any restriction of InP or any other substance integral to our systems could materially adversely affect our business, financial condition and operating results. In addition, if we experience a problem complying with these laws and regulations, it could cause an interruption or delay in our manufacturing operations or it could cause us to incur liabilities or costs related to health, safety or environmental remediation or compliance. We could also be subject to liability if we do not handle these substances in compliance with safety standards for handling, storage and transportation and applicable laws and regulations. If we experience a problem or fail to comply with such safety standards or laws and regulations, our business, financial condition and operating results may be harmed.

Regulations relating to environmental, social and governance matters, as well as customer and investor demands, may add operational complexity for us and may adversely affect our relationships with our customers, suppliers and investors.

There has been an increased focus on environmental, social and governance ("ESG") matters that affect companies globally, including by the SEC. A number of our customers have adopted, or may adopt, procurement policies that include environmental or social responsibility provisions or requirements that their suppliers should comply with, or they may seek to include such provisions or requirements in their procurement terms and conditions. An increasing number of investors are also requiring companies to disclose corporate ESG policies, practices and metrics. In addition, various jurisdictions are developing climate change-based laws or regulations that could cause us to incur additional direct costs for compliance, as well as indirect costs resulting from our customers, suppliers, or both, incurring additional compliance costs that are passed on to us. These legal and regulatory requirements, as well as investor expectations, on corporate ESG responsibility practices and disclosure, are subject to change, can be unpredictable, and may be difficult and expensive for us to comply with, given the complexity of our supply chain. If we are unable to comply with, or are unable to cause our suppliers or contract manufacturers to comply with such policies or provisions, or meet the requirements of our customers and investors, a customer may stop purchasing products from us or an investor may sell their shares, and may take legal action against us, which could harm our reputation, revenue and results of operations.

We are subject to global laws and regulations governing privacy, data protection, and cybersecurity that could adversely affect our business or subject us to liability.

Data privacy, data protection, and cybersecurity are areas of increasing focus for our customers, governmental regulators and privacy advocates, and many jurisdictions, including the E.U., the United States, China and other regions, are evaluating or have implemented laws and regulations relating to cybersecurity, privacy and data protection, which can affect the market and requirements for networking and communications equipment. For example, the General Data Protection Regulation (“GDPR”) in effect in the E.U., and similar regulatory standards in effect in the United Kingdom, the Personal Information Protection Law ("PIPL") in China, the California Consumer Privacy Act (“CCPA”) and the California Privacy Rights Act (“CPRA”), other enacted or proposed legislation in the United States, and enacted or proposed legislation in other jurisdictions have created new compliance obligations with respect to data processing, privacy, data protection, and cybersecurity.

The laws, rules, regulations, standards and other actual and asserted obligations relating to privacy, data protection and cybersecurity to which we may be subject, or that otherwise apply to our business, are constantly evolving, and we expect that there will continue to be new proposed laws, regulations and industry standards concerning these matters in the United States, the E.U. and other jurisdictions. We cannot fully predict the impact of the GDPR, the PIPL, the CCPA, the CPRA or other laws or regulations, including those that may be modified or enacted in the future, or new or evolving industry standards or actual or asserted obligations, relating to cybersecurity, privacy, or data protection or processing on our business or operations. These laws, regulations, and standards have required us to modify our practices and policies relating to privacy, data protection, cybersecurity, and data processing, and to incur substantial costs and expenses in an effort to comply, and we expect to continue to incur such costs and expenses in the future and may find it necessary or appropriate to further modify our relevant practices and policies. Any actual or perceived failure by us or our customers, partners or vendors to comply with laws, regulations, or other actual or asserted obligations to which we are or are alleged to be subject relating to cybersecurity, privacy or data protection could result in claims, litigation, and regulatory investigations and other proceedings, as well as damage to our reputation. These could result in substantial costs, diversion of resources, fines, penalties, and other damages, and harm to our customer relationships, our market position, and our ability to attract new customers. Any of these could harm our business, financial condition and results of operations.

A portion of our revenue is generated by sales to government entities, which are subject to a number of uncertainties, challenges, and risks.

We currently sell many of our solutions to various government entities, and we may in the future increase sales to government entities. Sales to government entities are subject to a number of risks, including risks related to a highly competitive, expensive, and time consuming sales process, which often requires significant upfront time and expense without any assurance that we will complete a sale. If we are successfully awarded a government contract, such award may be subject to appeals, disputes, or litigation, including, but not limited to, bid protests by unsuccessful bidders. Government demand and payment for our solutions may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our solutions. Government entities may also have statutory, contractual, or other legal rights to terminate contracts for convenience or due to a default. For purchases by the U.S. federal government, the government may require certain products to be made in, or be products of, the United States or other high-cost manufacturing locations, and all of our products may not be made in or products of jurisdictions that meet government requirements, and as a result, our business and results of operations may suffer. Contracts with government entities may also include preferential pricing terms, including, but not limited to, “most favored customer” pricing.

Additionally, we may be required to obtain special certifications to sell some or all of our solutions to government or quasi-government entities. Such certification requirements for our solutions may change, thereby restricting our ability to sell into the federal government sector until we have attained the revised certification. If our products and subscriptions are late in achieving or fail to achieve compliance with these certifications and standards, or our competitors achieve compliance with these certifications and standards before us, we may be disqualified from selling our products to such governmental entities, or be at a competitive disadvantage, which would harm our business, financial condition and results of operations. There are no assurances that we will find the terms for obtaining such certifications to be acceptable or that we will be successful in obtaining or maintaining the certifications.

As a government contractor or subcontractor, we must comply with laws, regulations, and contractual provisions relating to the formation, administration, and performance of government contracts and inclusion on government contract vehicles, which affect how we and our partners do business with government agencies. As a result of actual or perceived noncompliance with government contracting laws, regulations, or contractual provisions, we may be subject to non-ordinary course audits and internal investigations which may prove costly to our business financially, divert management time, or limit our ability to continue selling our products and services to our government customers. These laws and regulations may impose other added costs on our business, and failure to comply with these or other applicable regulations and requirements, including non-compliance in the past, could lead to claims for damages from our channel partners, downward contract price adjustments or refund obligations, civil or criminal penalties, termination of contracts or suspension or debarment from government contracting for a period of time with government agencies. Any such damages, penalties, disruption, or limitation in our ability to do business with a government would adversely impact, and could have a material adverse effect on, our business, financial condition, results of operations, reputation and growth prospects.

Our business could be adversely affected if our employees cannot obtain and maintain required security clearances or we cannot maintain a required facility security clearance, or we do not comply with legal and regulatory obligations regarding the safeguarding of classified information.

Our U.S. government contract revenue includes income derived from contracts that require our employees to maintain various levels of security clearances and may require us to maintain a facility security clearance, to comply with Department of Defense (“DoD”) requirements. The DoD has strict security clearance requirements for personnel who perform work in support of classified programs. In general, access to classified information, technology, facilities, or programs are subject to additional contract oversight and potential liability. In the event of a security incident involving classified information, technology, facilities, programs, or personnel holding clearances, we may be subject to legal, financial, operational, and reputational harm. We are limited in our ability to provide specific information about these classified programs, their risks, or any disputes or claims relating to such programs. As a result, investors have less insight into our classified programs than our other businesses and therefore less ability to fully evaluate the risks related to our classified business or our business overall. Obtaining and maintaining security clearances for employees involves a lengthy process, and it is difficult to identify, recruit, and retain employees who already hold security clearances. If our employees are unable to obtain security clearances in a timely manner, or at all, or if our employees who hold security clearances are unable to maintain their clearances or terminate employment with us, then a customer requiring classified work could terminate an existing contract or decide not to renew the contract upon its expiration. To the extent we are not able to obtain or maintain a facility security clearance, we may not be able to bid on or win new classified contracts, and existing contracts requiring a facility security clearance could be terminated.

Failure to comply with anti-bribery, anti-corruption, anti-money laundering laws, and similar laws, could subject us to penalties and other adverse consequences.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the UK Bribery Act, and possibly other anti-bribery and anti-money laundering laws in the United States and in countries outside of the United States in which we conduct our activities. Anti-corruption and anti-bribery laws have been enforced aggressively and are interpreted broadly to generally prohibit companies, their employees, agents, representatives, business partners, and third-party intermediaries from authorizing, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector.

We sometimes leverage third parties to sell our products and conduct our business abroad. We or our employees, agents, representatives, business partners or third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and may be held liable for the corrupt or other illegal activities of these employees, agents, representatives, business partners or third-party intermediaries even if we do not explicitly authorize such activities. We cannot assure you that all of our employees and agents will refrain from taking actions in violation of applicable law for which we may be ultimately held responsible. As we increase our international sales and business, our risks under these laws may increase.

These laws also require that we keep accurate books and records and maintain internal controls and compliance procedures designed to prevent any such actions. While we have policies and procedures to address compliance with such laws, we cannot assure you that none of our employees, agents, representatives, business

partners or third-party intermediaries will take actions in violation of our policies and applicable law, for which we may be ultimately held responsible.

Any allegations or violation of the FCPA or other applicable anti-bribery, anti-corruption laws, and anti-money laundering laws could result in whistleblower complaints, sanctions, settlements, prosecution, enforcement actions, fines, damages, adverse media coverage, investigations, loss of export privileges, severe criminal or civil sanctions, or suspension or debarment from U.S. government contracts, all of which may have an adverse effect on our reputation, business, results of operations, and prospects. Responding to any investigation or action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other professional fees.

General Risk Factors

The trading price of our common stock has been volatile and may be volatile in the future.

The trading prices of our common stock and the securities of other technology companies have been and may continue to be highly volatile. Factors affecting the trading price of our common stock include:

•variations in our operating results;

•announcements of technological innovations, new services or service enhancements, strategic alliances or agreements by us or by our competitors;

•the gain or loss of customers;

•recruitment or departure of key personnel;

•changes in the estimates of our future operating results or external guidance on those results or changes in recommendations or business expectations by any securities analysts that elect to follow our common stock;

•mergers and acquisitions by us, by our competitors or by our customers or suppliers;

•market conditions in our industry, the industries of our customers and the economy as a whole, including global trade tariffs, supply chain disruptions, and fluctuations in currency exchange rates, interest rates or inflation rates;

•social, geopolitical, environmental or health factors, including pandemics or widespread health epidemics such as the COVID-19 pandemic; and

•adoption or modification of regulations, policies, procedures or programs applicable to our business.

An economic downturn, negative financial news, continued inflation, high interest rates, declines in income or asset values, market conditions, changes to fuel and other energy costs, and other economic factors, may lead to market volatility and associated uncertainty. In addition, if the market for technology stocks or the broader stock market experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or results of operations. Each of these factors, among others, could harm the value of your investment in our common stock. Some companies that have had volatile market prices for their securities have had securities class action lawsuits filed against them. If a suit were filed against us, regardless of its merits or outcome, it could result in substantial costs and divert management’s attention and resources.

Future sales of our common stock could cause our stock price to fall.

We have sold, and plan in the future to sell, shares of our common stock in underwritten offerings and have established, and may in the future establish, “at-the-market” offering programs pursuant to which we may offer and sell shares of our common stock. Sales of securities have resulted and will continue to result in dilution of our existing stockholders, and such sales could cause our stock price to fall.

In addition, if our existing stockholders sell, or indicate an intent to sell, a large number of shares of our common stock in the public market, it could cause our stock price to fall. We may also issue shares of common stock or securities convertible into our common stock from time to time in connection with financings, acquisitions, investments or otherwise. Any such issuance would result in dilution to our existing stockholders and could cause our stock price to fall.

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our common stock.

We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law, which apply to us, may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. Our amended and restated certificate of incorporation and amended and restated bylaws:

•authorize the issuance of “blank check” convertible preferred stock that could be issued by our board of directors to thwart a takeover attempt;

•establish a classified board of directors, as a result of which the successors to the directors whose terms have expired will be elected to serve from the time of election and qualification until the third annual meeting following their election;

•require that directors only be removed from office for cause;

•provide that vacancies on the board of directors, including newly created directorships, may be filled only by a majority vote of directors then in office rather than by stockholders;

•prevent stockholders from calling special meetings; and

•prohibit stockholder action by written consent, requiring all actions to be taken at a meeting of the stockholders.

Our amended and restated bylaws designate the Court of Chancery of the State of Delaware and the federal district courts of the United States of America as the exclusive forums for substantially all disputes between us and our stockholders, which will restrict our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, any other state or federal court located in the State of Delaware, is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws; or any action asserting a claim governed by the internal affairs doctrine. However, such exclusive forum provisions would not apply to any such claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within 10 days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than such court or for which such court does not have subject matter jurisdiction.

These provisions would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the U.S. federal courts have exclusive jurisdiction. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. Our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may

nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated bylaws. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find such exclusive-forum provisions to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could harm our business.

Events that are outside our control, such as natural disasters, violence or other catastrophic events, could harm our operations.

Our headquarters and the majority of our infrastructure, including our PIC fabrication manufacturing facility, are located in Northern California, an area that is susceptible to earthquakes, fires, floods and other natural disasters. Further, attacks and violence aimed at Northern California or at the United States energy or telecommunications infrastructure could hinder or delay the development and sale of our products. In the event that an earthquake, targeted attack or other man-made or natural catastrophe were to destroy any part of our or our contract manufacturers’ or suppliers' facilities, destroy or disrupt vital infrastructure systems, or interrupt our operations or supply chain for any extended period of time, our business, financial condition and results of operations would be harmed. For related risks concerning the operations and availability of the storage facilities in which our inventory is held, see also the Risk Factor titled "Our international sales and operations subject us to additional risks that may harm our operating results."

ITEM 2. PROPERTIES

Our headquarters are located in San Jose, California, which consist of approximately 82,000 square feet under lease. As of December 31, 2022, we leased approximately 57,000 square feet for research and development and manufacturing in Sunnyvale, California.

In addition to the leased buildings in San Jose and Sunnyvale, California, we also lease approximately 483,000 square feet of office spaces for research and development centers and for sales, service and support in various countries within (i) North America; (ii) LATAM; (iii) EMEA; and (iv) APAC.

All of these leases expire between 2023 and 2031. We also own a facility in Allentown, Pennsylvania. We intend to adjust our facility space to meet our requirements and we believe that suitable additional or substitute space will be available as needed to accommodate our business needs for our operations. We believe that our existing facilities are adequate to meet our business needs through the next 12 months.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Annual Report on Form 10-K contains “forward-looking statements” that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. Such forward-looking statements include, but are not limited to, our expectations regarding revenue, gross margin, operating expenses, cash flows and other financial items; the severity, magnitude, duration and effects of supply chain challenges and logistics issues; the extent to which the COVID-19 pandemic or other public health concerns and related impacts will materially and adversely affect our business operations, financial performance, results of operations, financial position, stock price and personnel; achievement of strategic objectives; any statements regarding our plans, strategies and objectives; the impact of new customer network footprint on our gross margin; our anticipated diversified customer base; our opportunities to grow revenue by driving adoption of new and existing solutions; expansion of our vertical integration capabilities across more of our product portfolio utilizing our ICE6 optical engine and related impacts on gross margin; cost management with investments in technology innovation; our go-to-market efforts globally to expand our customer reach and drive additional market share gains in the long term; future investments in our direct sales force; the portion of our future revenue attributable to direct sales; the effects of seasonal patterns in our business; the variable length of our sales cycle; factors that may affect our operating results; investments in research and development to support our strategy of expanding our vertically integrated product portfolio, including bringing new products to market quickly; anticipated customer acceptance of our solutions; statements concerning new products or services, including new product features; our beliefs about who we may compete with and how we are differentiated from those competitors; statements regarding our production capacity and facilities requirements; statements related to capital expenditures; statements related to working capital and liquidity; our ability to realize deferred tax assets; statements related to future economic conditions, performance, market growth, competitor, supplier or customer consolidation, or our sales cycle; our ability to identify, attract and retain highly skilled personnel; statements regarding our corporate culture; our ability to protect our technology and intellectual property, the frequency of claims related to our intellectual property and the value of our intellectual property; statements regarding restructuring of our business, acquisitions, or other strategic transactions; statements related to our convertible senior notes and credit facility; statements related to the impact of tax regulations; statements related to the proliferation and impact of environmental regulation; statements related to the effects of litigation on our financial position, results of operations or cash flows; statements related to factors beyond our control, such as natural disasters, acts of war or terrorism, epidemics and pandemics; statements related to new accounting standards; statements as to industry trends and other matters that do not relate strictly to historical facts; and statements of assumptions underlying any of the foregoing. These statements are often identified using words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” "should," "will," or "would," and similar expressions or variations.

Overview

We are a semiconductor manufacturer and global supplier of networking solutions comprised of networking equipment, optical semiconductors, software and services. Our portfolio of solutions includes optical transport platforms, converged packet-optical transport platforms, compact modular platforms, optical line systems, coherent optical engines and subsystems, a suite of networking and automation software offerings, and support and professional services. Leveraging our U.S.-based compound semiconductor fab and in-house packaging capabilities, we design, develop, and manufacture industry-leading indium phosphide-based PICs for use in our vertically integrated, high-capacity optical communications products.

Our customers include operators of fixed and mobile networks, including telecommunications service providers, ICPs, cable providers, wholesale carriers, research and educational institutions, large enterprises, utilities and government entities. Our networking solutions enable our customers to deliver high-bandwidth business and consumer communications services. Our comprehensive portfolio of networking solutions also enables our customers to scale their transport networks as end-user services and applications continue to drive growth in demand for network bandwidth. These end-user services and applications include, but are not limited to, high-speed internet access, business ethernet services, 4G/5G mobile broadband, cloud-based services, high-definition video streaming services, virtual and augmented reality, IoT, business Ethernet services and DCI.

As an optical semiconductor manufacturer, we specialize in the manufacturing of optical compound semiconductors using InP. This technology is used in telecommunications networks to transmit massive amounts of data and power, critical communications services like 5G, enhanced broadband, and high-capacity data center connectivity. We have made significant investments in our unique research, development, fabrication, and packaging facilities, including our optical compound semiconductor fab in Silicon Valley. We optimize the manufacturing process by using InP to build our PICs, which enables the integration of hundreds of optical functions onto a onto a single, monolithic optical semiconductor chip. The unique capabilities of our optical semiconductor fab, which has provided our customers with a critical and secure source of U.S.-produced optical semiconductors and strengthened the supply chain, have enabled us to consistently pioneer critical technology advancements. For example, our latest generation of technology has made it possible to transmit information at a rate of 800 Gb/s using a single laser.

The large-scale integration of our PICs and advanced DSPs enables us to develop and manufacture high-performance optical engines that are used in our coherent optical networking system and subsystem solutions. These solutions include features that customers care about the most, including reduced cost per bit, lower footprint and power consumption, and improved performance, reliability and security. Coherent optical solutions are becoming increasingly important across the network as our customers transition to 800 Gb/s per wavelength transmission speeds and beyond in the core, 400 Gb/s in the metro, and 100 Gb/s in the access market segment. We believe our vertical integration strategy provides a competitive advantage by enabling leading optical performance at higher optical speeds with increased spectral efficiency, greater control over our supply chain, and a lower cost structure.

We have grown our solutions portfolio through internal development as well as acquisitions, including the acquisition of Coriant, a privately held global supplier of open network solutions for the largest global network operators. These developments positioned us to be one of the leading providers of vertically integrated optical networking solutions in the world with the ability to serve a global customer base with accelerated delivery of the innovative solutions our customers demand. In 2021, we announced an expansion of our portfolio with the introduction of a suite of coherent optical pluggables designed to seamlessly address the rapidly growing market for point-to-point solutions as well as create a new category of point-to-multipoint solutions that can enable a dramatically more cost-efficient network architecture. Based on our vertically integrated optical semiconductor technology and supporting a range of high-speed transport rates that include 800 Gb/s, 400 Gb/s and 100 Gb/s, this suite of coherent optical pluggables builds on our history of delivering innovative, highly differentiated, and vertically integrated coherent optical engines.

We sell our products to end-user customers and third-party network equipment manufacturers via a direct sales force and through indirect channel partners.

Impact of COVID-19 Pandemic

We continue to monitor the COVID-19 pandemic and actively assess potential implications to our business, supply chain, customer fulfillment sites, support operations and customer demand. We are also continuing to take appropriate measures to protect the health and safety of our employees and to create and maintain a safe working environment. While the effects of the COVID-19 pandemic have been decreasing, if the COVID-19 pandemic or its adverse effects become more severe or prevalent in the future or are prolonged in the locations where we, our customers, suppliers or contract manufacturers conduct business, or we experience more pronounced disruptions in our operations, or in economic activity and demand generally, our business and results of operations in future periods could be materially adversely affected.

Financial and Business Highlights

Total revenue was $1,573.2 million in 2022 as compared to $1,425.2 million in 2021, representing a 10% increase. The year-over-year increase in revenue was driven by the ramp of new products, particularly ICE6, and revenue growth in our ICP vertical in the United States and our other service provider vertical in the United States and APAC. This growth was partially offset by lower revenue from certain Tier 1 customers and each of our other service provider and ICP verticals in EMEA and in our cable vertical in the United States. In 2023, we anticipate benefiting from a diversified customer base and see several prospective opportunities to grow revenue by driving adoption of new and existing solutions. Our results will depend on overall market conditions and, as is typical, quarter-over-quarter revenue could be volatile, affected by, among other factors, customer buying patterns, supply chain disruptions and the timing of customer network deployments.

Gross margin decreased to 34% in 2022 from 35% in 2021. The year-over-year decrease in gross margin was primarily driven by higher costs related to component price increases, higher logistics and freight costs, and supply constrained manufacturing volumes, partially offset by quality initiatives and ongoing cost improvements. In this period, our margins benefited from improved product mix including increased revenue from vertically integrated products. In 2023, we intend to continue to expand our vertical integration capabilities across more of our product portfolio utilizing our ICE6 optical engine and expect to benefit from the partial relief of elevated supply chain costs, both of which should help drive continued gross margin improvement over time.

Operating expenses increased to $595.9 million in 2022 from $585.5 million in 2021, representing a 2% increase. This increase was primarily attributable to higher employee-related costs, costs related to bringing our new technologies to market and investments in future technologies. These increases were partially offset by lower restructuring costs and amortization of our acquired intangibles. In 2023, we intend to continue to balance prudent cost management with investments in technology innovation and our go-to-market efforts globally to expand our customer reach and drive additional market share gains in the long term.

One customer accounted for approximately 11% of our revenue in 2022. No customer accounted for over 10% of our revenue in 2021.

We primarily sell our products through our direct sales force, with the remainder sold indirectly through channel partners. We derived 76% and 77% of our revenue from direct sales to customers in 2022 and 2021, respectively. In the future, we expect to continue generating a majority of our revenue from direct sales.

We are headquartered in San Jose, California, with employees located throughout North America, LATAM, EMEA and APAC.

Revenue

2022 Compared to 2021. Product revenue increased by $169.2 million, or 15%, in 2022 from 2021. This increase was driven by the ramp of new products, particularly ICE6, and growth in each of our ICP and other

service provider verticals. This increase was partially offset by lower revenue from certain Tier 1 customers and continued supply constraints.

Services revenue decreased by $21.2 million, or 7%, in 2022 from 2021. This decrease was attributable to a decline in professional services revenue. This decline was primarily related to network installation delays, which were driven by customer readiness and supply constraints.

In line with typical seasonality in our industry, we expect our total revenue will be lower in the first quarter of 2023 as compared to the fourth quarter of 2022.

Revenue by geographic region is based on the shipping address of the customer. The following tables summarize our revenue by geography and sales channel for the periods presented (in thousands, except percentages):

2022 Compared to 2021. Domestic revenue increased by $206.5 million, or 31%, in 2022 compared to 2021, driven primarily by increased revenue from each of our ICP and other service provider verticals, which was partially offset by decreased revenue from certain Tier 1 customers and our cable vertical.

International revenue decreased by $58.4 million, or 8%, in 2022 compared to 2021. In this period, EMEA revenue decreased in each of our other service provider and cable verticals and from certain Tier 1 customers, including from our suspension of operations in Russia. Our Other Americas revenue also decreased in our other service provider vertical during this period. This decline was partially offset by increased revenue in APAC in our other service provider vertical.

Direct revenue increased by $92.0 million, or 8%, in 2022 compared to 2021, driven primarily by increased revenue from each of our ICP and other service provider verticals which was partially offset by decreased revenue from certain Tier 1 customers.

Indirect revenue increased $56.1 million, or 17%, driven primarily by increased revenue from customers in each of our ICP and other service provider verticals who purchased through our indirect sales channel.

Cost of Revenue and Gross Margin

2022 Compared to 2021. Gross profit increased by $37.8 million, with gross margin decreasing to 34% in 2022 from 35% in 2021. The gross margin decrease was primarily driven by higher costs related to component price increases, higher logistics and freight costs, and supply constrained manufacturing volumes, partially offset by ongoing cost improvement and quality initiatives. In this period, our margins benefited from improved product mix including increased revenue from vertically integrated products as well as reductions in restructuring costs. In 2023, we intend to continue to expand our vertical integration capabilities across more of our product portfolio utilizing our ICE6 optical engine and expect to benefit from the partial relief of elevated supply chain costs, both of which should help drive continued gross margin improvement over time.

In any given quarter, gross margins can fluctuate based on a number of factors, including the mix of line system footprint versus capacity utilization, product mix, customer mix and overall volume.

Amortization of Intangible Assets

2022 Compared to 2021. Amortization of intangible assets increased by $3.5 million, or 18%, in 2022 from 2021. The increase was due to the shortened life of certain developed technologies resulting from us having exited certain product lines in the fourth quarter of 2021.

Restructuring and Other Related Costs

2022 Compared to 2021. Restructuring and other related costs decreased $1.3 million, or 85%, in 2022 from 2021 reflecting the substantial completion of our 2021 Restructuring Plan as well as the completion of our 2020 Restructuring Plan in 2022. See Note 9, “Restructuring and Other Related Costs” to the Notes to Consolidated Financial Statements for more information on our restructuring plans.

Total	$	51,530	$	43,884	$	41,676

Research and Development Expenses

2022 Compared to 2021. Research and development expenses increased by $6.3 million, or 2%, in 2022 from 2021. The increase was primarily attributable to higher employee-related expenses, material costs, and equipment costs related to bringing our new technologies to market and investments in future technologies. These costs were offset by lower facility costs due to site optimization and lower depreciation related to legacy technologies. In 2023, we expect to make additional targeted innovation investments in research and

development to support our strategy of expanding our vertically integrated product portfolio, including bringing new products to market quickly.

Sales and Marketing Expenses

2022 Compared to 2021. Sales and marketing expenses increased by $7.6 million, or 5%, in 2022 from 2021. This increase was driven by higher employee-related expenses including higher commissions and other costs, increased travel as COVID-related restrictions eased, and higher marketing costs related to the resumption of in-person trade shows partially offset by lower facility costs and spending on trial equipment. In 2023, we plan to increase investments in our go-to-market efforts globally to expand our customer reach and drive additional market share gains in the long term.

General and Administrative Expenses

2022 Compared to 2021. General and administrative expenses increased by $3.2 million, or 3%, in 2022 from 2021. The increase was attributable to higher employee-related expenses, outside professional fees, and indirect tax expenses partially offset by lower litigation settlement costs.

Amortization of Intangible Assets

2022 Compared to 2021. Amortization of intangible assets decreased by $2.9 million in 2022 from 2021. The decreases were largely due to lower amortization of the value of customer relationships and backlog intangibles. Customer relationships and backlog intangibles are amortized over the expected customer lives.

Acquisition and Integration Costs

2022 Compared to 2021. Acquisition and integration costs decreased by $0.6 million in 2022 from 2021 primarily due to the completion of our integration efforts related to the Acquisition in the first quarter of 2021.

Restructuring and Other Related Costs

2022 Compared to 2021. Restructuring and other related costs decreased by $3.1 million in 2022 compared to 2021. The decrease was primarily due to lower severance and other related expenses and asset impairment charges, partially offset by lease-related impairment charges incurred for various sites. See Note 9, “Restructuring and Other Related Costs” to the Notes to Consolidated Financial Statements for more information on our restructuring plans.

2022 Compared to 2021. Interest income was immaterial.

Interest expense decreased by $23.1 million in 2022 compared to 2021, primarily due to the adoption of ASU 2020-06, which resulted in the elimination of the debt discounts for our convertible senior notes that were amortized to interest expense over their contractual terms prior to its adoption, offset by the write off of unamortized deferred debt issuance costs related to the asset-based revolving credit facility under the Prior Credit Agreement. See Note 12, “Debt” to the Notes to Condensed Consolidated Financial Statements for more information.

Gain on extinguishment of debt was $15.5 million in 2022 due to the partial repurchase of our 2024 Notes at a price that was below their par value. The gain includes and was reduced by the write-off of related deferred issuance costs of $3.5 million.

The change in other gain (loss), net, 2022 compared to 2021, was $36.9 million primarily due to an increase in unrealized foreign exchange gains driven by foreign currency exchange rate changes.

Provision for Income Taxes

We recognized an income tax expense of $20.5 million on a loss before income taxes of $55.5 million, $12.0 million on a loss before income taxes of $158.8 million, and $6.0 million on a loss before income taxes of $200.7 million in 2022, 2021 and 2020, respectively. The resulting effective tax rates were (37.1)%, (7.5)% and (3.0)% for 2022, 2021 and 2020, respectively. The 2022 and 2021 effective tax rates differ from the expected statutory rate of 21% based on our ability to benefit from our U.S. loss carryforwards, offset by state income taxes, non-deductible stock-based compensation expenses and foreign taxes provided on foreign subsidiary earnings. The increase in 2022 income tax provision compared to 2021 is mainly driven by an increase in income taxes and withholding taxes in certain non-U.S. jurisdictions where our local subsidiaries do not have carryforward losses to offset income.

During 2022, we implemented a realignment of our internal supply chain and customer facing entities. The new structure aligned and consolidated our intellectual property and the associated commercial risk and reward among the customer-facing entities in their internal supply chain and improved operational efficiency. The impact of this internal realignment is reflected in our tax provision for the year ended December 31, 2022.

Because of our U.S. operating loss in 2022, significant loss carryforward position, and corresponding valuation allowance in all years, other than separate filing state taxes, a few combined states and minimum taxes, we have not been subject to federal or state tax on our U.S. income because of the availability of loss carryforwards. If these losses and other tax attributes become fully utilized, our taxes will increase significantly to a more normalized, expected rate on U.S. earnings. The release of transfer pricing reserves in the future may have a beneficial impact to tax expense, but the timing of the impact depends on factors such as expiration of the statute of limitations or settlements with tax authorities. No significant releases are expected in the near future based on information available at this time.

Operating Activities

Net cash used by operating activities was $37.6 million for 2022, as compared to net cash provided by operating activities of $28.1 million for 2021 and net cash used by operating activities of $112.3 million for 2020.

Net loss for 2022 was $76.0 million, which included non-cash charges of $152.1 million such as depreciation, stock-based compensation, amortization of intangibles assets, operating lease expense, restructuring charges and related costs, and amortization of debt issuance costs, compared to a net loss of $170.8 million in 2021, which included non-cash charges of $193.8 million. Net cash used in working capital was $113.7 million in 2022. Accounts receivable increased by $69.0 million due to higher billings to customers and timing of collections. Inventory levels increased by $89.5 million due to our efforts to purchase more inventory to manage lead time challenges resulting from the industry-wide supply chain environment. Prepaid and other assets increased by $34.0 million primarily due to increase in contract manufacturer deposits and increase in customer contract assets. Accounts payable increased by $88.3 million primarily due timing of payments to suppliers. Accrued liabilities and other expenses decreased by $24.4 million primarily due to timing of payments of other compensation related expenses and decreased restructuring and tax liabilities. Deferred revenue increased by $15.1 million due to higher maintenance renewals during the period attributable to expanding our installed base. Maintenance contracts are typically contracted on an annual or multi-year basis.

Net loss for 2021 was $170.8 million, which included non-cash charges of $193.8 million such as depreciation, stock-based compensation, amortization of intangibles assets, operating lease expense, restructuring charges and related costs, and amortization of debt discount and debt issuance costs, compared to a net loss of $206.7 million in 2020, which included non-cash charges of $206.2 million. Net cash provided by working capital was $5.1 million in 2021. Accounts receivable increased by $45.8 million due to higher billings to customers and timing of collections. Inventory levels increased by $28.0 million due to longer lead time on supply which required more inventory on hand and higher service inventory to meet customer service level agreements. Prepaid and other assets decreased by $0.4 million primarily due to timing of value-added tax and income tax payments and increase in customer contract assets. Accounts payable increased by $32.3 million primarily due timing of payments to suppliers. Accrued liabilities and other expenses increased by $39.3 million primarily due to accrual of 2021 corporate bonus, restructuring liabilities, tax liabilities, purchases of shares of our common stock under our 2007 Employee Stock Purchase Plan (the “ESPP”) in 2021 and no accrual for 2020 corporate bonus. Deferred revenue increased by $7.8 million due to higher maintenance renewals during the period attributable to expanding our installed base. Maintenance contracts are typically contracted on an annual or multi-year basis.

Investing Activities

Net cash used in investing activities was for the purchase of property and equipment and amounted to $46.1 million and $41.4 million for 2022 and 2021, respectively.

Financing Activities

Net cash provided by financing activities was $82.3 million for 2022. Financing activities in 2022 primarily included net proceeds of $92.9 million from issuance of the 2028 Notes and partial repurchase of the 2024 Notes, and $15.2 million from the issuance of shares of our common stock under the ESPP. These proceeds were offset by $7.7 million term license purchases, $12.5 million payment of debt issuance costs incurred in connection with the issuance of the 2028 Notes and entering into the asset-based revolving credit facility under the Loan Agreement, $1.3 million payments on finance lease obligations, and tax withholdings in the amount of $3.7 million paid on behalf of certain employees for net share settlements of restricted stock units (“RSUs”).

Net cash used in financing activities was $101.5 million for 2021. Financing activities in 2021 included repayments of $77.0 million under the Credit Facility and $24.6 million under the financing assistance arrangement, and payments of $1.6 million for finance lease obligations and $7.3 million for term license purchases. The period also included net proceeds of $16.5 million from the issuance of shares under our ESPP and the exercise of stock options. These proceeds were offset by tax withholdings of $7.2 million paid on behalf of certain employees for net share settlements of RSUs.

Liquidity

We believe that our current cash, along with the Credit Facility (as defined below) will be sufficient to meet our anticipated cash needs for working capital and capital expenditures, and the interest payments on the convertible senior notes and the Credit Facility for at least 12 months. If the impact to our business and financial position of the supply chain challenges and disruptions in the global economy and financial markets is more

extensive or prolonged than expected and our existing sources of cash are insufficient to satisfy our liquidity requirements, we may require additional capital from equity or debt financings to fund our operations, to respond to competitive pressures or strategic opportunities, or otherwise. In addition, we are continuously evaluating alternatives for efficiently funding our capital expenditures and ongoing operations. We may, from time to time engage in a variety of financing transactions for such purposes. We may not be able to secure timely additional financing, or restructure existing debt, on favorable terms or at all. The terms of any additional financings or restructurings may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity or equity-linked securities, our existing stockholders could suffer dilution in their percentage ownership of us, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock.

On August 8, 2022, we issued the 2028 Notes, which will mature on August 1, 2028, unless earlier repurchased, redeemed or converted. Interest is payable semi-annually in arrears on February 1 and August 1 of each year, which commenced on February 1, 2023. In the event that all of the 2028 Notes are converted, we would be required to repay the principal amount in cash and the conversion premium in any combination of cash and shares of its common stock at our election.

On March 9, 2020, we issued the 2027 Notes, which will mature on March 1, 2027, unless earlier repurchased, redeemed or converted. Interest is payable semi-annually in arrears on March 1 and September 1 of each year, which commenced on September 1, 2020. For the conversion obligation, we intend to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock, at our election.

On September 11, 2018, we issued the 2024 Notes, which will mature on September 1, 2024, unless earlier repurchased, redeemed or converted. Interest is payable semi-annually in arrears on March 1 and September 1 of each year, which commenced on March 1, 2019. For the conversion obligation, we intend to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock, at our election.

For more information regarding the convertible senior notes, see Note 12, “Debt” to the Notes to Consolidated Financial Statements. Refer to the contractual obligations section below for future payment obligations.

On June 24, 2022, we entered into a Loan, Guaranty and Security Agreement (the "Loan Agreement") with the lenders party thereto, and Bank of America, N.A., as agent. The Loan Agreement provides for a senior secured asset-based revolving credit facility of up to $200 million (the "Credit Facility"), which we may draw upon from time to time. We may increase the total commitments under the revolving credit facility by up to an additional $100 million, subject to certain conditions. In addition, the Loan Agreement provides for a $50 million letter of credit subfacility and a $20 million swingline loan facility.

As of December 31, 2022, we had no drawings on the Credit Facility and we had availability of $161.6 million under the Credit Facility. For more information regarding the Credit Facility, see Note 12, “Debt” to the Notes to Consolidated Financial Statements.

As of December 31, 2022, we had $189.2 million of cash, cash equivalents and restricted cash including $65.9 million of cash held by our foreign subsidiaries. Our policy with respect to undistributed foreign subsidiaries' earnings is to consider those earnings to be indefinitely reinvested. As a result of the enactment in the United States of the Tax Cuts and Jobs Act of 2017, if and when funds are actually distributed in the form of dividends or otherwise, we expect minimal tax consequences, including foreign withholding taxes, which would be applicable in some jurisdictions.

We had standby letters of credit and bank guarantees as of the years ended December 31, 2022 and December 25, 2021. See Note 14, “Guarantees” to the Notes to Consolidated Financial Statements for further information.

Contractual Obligations

The following is a summary of our contractual obligations as of December 31, 2022 and December 25, 2021 (in thousands):


	December 31, 2022		December 25, 2021		Change		% Change
Operating leases(1)	$	71,903	$	90,887	$	(18,984)	(21)	%

(1)We lease facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 11 years, and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to six years. We also have contractual commitments to remove leasehold improvements and return certain properties to a specified condition when the leases terminate. See Note 13, "Commitments and Contingencies" to the Notes to Consolidated Financial Statements for more information.

(2)We have service agreements with certain production suppliers under which we are committed to purchase certain parts. The increase in purchase obligations compared with the end of fiscal 2021 was primarily due to increased lead-time commitments required to secure supply and pricing for certain product components as well as investments to support the release of new products.

(3)For additional information regarding our asset-based revolving credit facility and 2028, 2027 and 2024 Notes, see Note 12, “Debt” to the Notes to Consolidated Financial Statements.

(4)Certain commitments and contingencies are not included in the table because we cannot reliably estimate the timing and amount of future payments, if any. For example, tax liabilities of $9.6 million related to uncertain tax positions and expected future payments to our pension and post-employment plans are excluded from the contractual obligation table because they do not represent contractual cash outflows as they are dependent on various factors. See Note 18, "Employee Benefit and Pension Plans" to the Notes to Consolidated Financial Statements for more information relating to our pension and post-retirement benefit plans.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. These accounting principles require us to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. See Note 2, “Significant Accounting Policies” to the Notes to Consolidated Financial Statements, which is included in Part II, Item 8 of this Annual Report on Form 10-K. Financial Statements and Supplementary Data, which describes our significant accounting policies and methods used in preparation of our consolidated financial statements. Management believes that the estimates, assumptions and judgments upon which they rely are reasonable based upon information available to them at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected.

We believe our critical accounting policies and estimates are those related to revenue recognition, accounting for income taxes, and inventory valuation. Management considers these policies critical because they are both important to the portrayal of our financial condition and results of operations, and they require management to make judgments and estimates about inherently uncertain matters.

Revenue Recognition

We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

We determine revenue recognition by applying the following five-step approach:

•identification of the contract, or contracts, with a customer;

•identification of the performance obligations in the contract;

•determination of the transaction price;

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

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

Many of our product sales are sold in combination with installation and deployment services along with initial hardware and software support. Our product sales are also sold at times with spares management, on-site hardware replacement services, network operations management, software subscription services, extended hardware warranty and training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription services include software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.

Spares management and on-site hardware replacement services include the replacement of defective units at customer sites in accordance with specified service level agreements. Network operations management includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. We evaluate each promised good and service in a contract to determine whether it represents a distinct performance obligation or should be accounted for as a combined performance obligation.

Services revenue includes software subscription services, installation and deployment services, spares management, on-site hardware replacement services, network operations management, extended hardware warranty and training. Revenue from software subscription services, spares management, on-site hardware replacement services, network operations management and extended hardware warranty contracts is deferred and is recognized ratably over the contractual support period, which is generally one year, as services are provided over the course of the entire period. Revenue related to training and installation and deployment services is recognized upon completion of the services.

Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. We typically satisfy our performance obligations upon shipment or delivery of product depending on the contractual terms. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. We assess our ability to collect from our customers based primarily on the creditworthiness and past payment history of the customer.

Customer product returns are generally approved on a case by case basis. Specific reserve provisions are made based upon a specific review of all the approved product returns where the customer has yet to return the products to generate the related sales return credit at the end of a period. Estimated sales returns are recorded as a reduction to revenue.

For sales to resellers, the same revenue recognition criteria apply. It is our practice to identify an end-user prior to shipment to a reseller. We do not offer rights of return or price protection to our resellers.

We report revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Customer Purchase Commitments

We sell software licenses that provide customers the ability to purchase incremental bandwidth capacity on an already-deployed piece of hardware. Instant Bandwidth-enabled systems generally include a specific initial capacity and incremental capacity can be added by the purchase of Instant Bandwidth licenses. Instant Bandwidth licenses are considered distinct performance obligations because customers can provision additional transmission capacity on demand without the deployment of any incremental equipment.

Some contracts commit the customer to purchase incremental Instant Bandwidth licenses within a specified time frame from the initial shipment of the Instant Bandwidth-enabled hardware. The time frame varies by customer and generally ranges between 12 to 24 months. If the customer does not purchase the additional capacity within the time frame as stated in the contract, we have the right to deliver and invoice such Instant Bandwidth licenses to the customer. Future committed licenses are considered to be additional performance obligations when a minimum purchase obligation is present, as evidenced by enforceable rights and obligations. As such, we are required to estimate the variable consideration for future Instant Bandwidth licenses as part of determining the contract transaction price.

Contract Termination Rights

The contract term is determined on the basis of the period over which the parties to the contract have present enforceable rights and obligations. Certain customer contracts include a termination for convenience clause that allows the customer to terminate services without penalty, upon advance notification. For such contracts, the service duration is limited to the non-cancelable portion of the contract.

Variable Consideration

The consideration associated with customer contracts is generally fixed. Variable consideration includes discounts, rebates, refunds, credits, incentives, penalties, or other similar items. The amount of consideration that can vary is not a substantial portion of total consideration.

Variable consideration estimates are re-assessed at each reporting period until a final outcome is determined. The changes to the original transaction price due to a change in estimated variable consideration will be applied on a retrospective basis, with the adjustment recorded in the period in which the change occurs.

Stand-alone Selling Price

Stand-alone selling price is the price at which an entity would sell a good or service on a stand-alone (or separate) basis at contract inception. Under this model, the observable price of a good or service sold separately provides the best evidence of stand-alone selling price. However, in certain situations, stand-alone selling prices will not be readily observable and the entity must estimate the stand-alone selling price.

When allocating on a relative stand-alone selling price basis, any discount provided in the contract is generally allocated proportionately to all of the performance obligations in the contract.

The majority of products and services offered by us have readily observable selling prices. For products and services that do not, we generally estimate stand-alone selling price using the market assessment approach based on expected selling price and adjust those prices as necessary to reflect our costs and margins. As part of our stand-alone selling price policy, we review product pricing on a periodic basis to identify any significant changes and revise our expected stand-alone selling price assumptions as appropriate.

Transaction Price Allocated to the Remaining Performance Obligation

Our remaining performance obligations represent the transaction price allocated to performance obligations that are unsatisfied or partially satisfied, as of period end, consisting of deferred revenue and backlog. Our backlog represents purchase orders received from customers for future product shipments and services that are unsatisfied or partially satisfied as of period end. Our backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, may be canceled without penalty. Orders in backlog may be fulfilled several quarters following receipt or may relate to multi-year support service obligations.

Accounting for Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate our taxes in each of the jurisdictions in which we operate. We estimate actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in our consolidated statements of operations become deductible expenses under applicable income tax laws or loss, or credit carryforwards are utilized. Accordingly, realization of our deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.

We must assess the likelihood that some portion or all of our deferred tax assets will be recovered from future taxable income within the respective jurisdictions. To the extent the Company believes that recovery does not meet the “more-likely-than-not” standard, it must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including the Company's forecast of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors. Based on the available objective evidence, at December 31, 2022, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.

Inventory Valuation

Inventories consist of raw materials, work-in-process and finished goods and are stated at standard cost adjusted to approximate the lower of actual cost or net realizable value. Costs are recognized utilizing the first-in, first-out method. Net realizable value is based upon an estimated selling price reduced by the estimated cost of disposal. The determination of market value involves numerous judgments including estimated average selling prices based upon recent sales volumes, industry trends, existing customer orders, current contract price, future demand and pricing and technological obsolescence of our products.

Inventory that is obsolete or in excess of our forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing our inventory costs and deferred inventory costs, we considered whether the net realizable value of inventory delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. We concluded that, in the instances where the net realizable value of inventory delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at cost or net realizable value, whichever is lower, thereby recognizing the cost of the reduction in net realizable value of inventory in the period in which the reduction occurred or can be reasonably estimated. We have, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of actual cost or net realizable value.

We consider whether we should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contractual purchase price, we have also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.

See Note 2, “Significant Accounting Policies” to the Notes to Consolidated Financial Statements for a full description of recent accounting pronouncements including the respective expected dates of adoptions and effects on us.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

We operate in international markets, which expose us to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and various foreign currencies, the most significant of which is the euro. The majority of our revenue contracts are denominated in U.S. dollars, with the most significant exception being in Europe, where we invoice primarily in euros and SEK. Additionally, a portion of our expenses, primarily the cost of personnel for research and development and sales and sales support to deliver technical support on our products and professional services and the cost to manufacture, are denominated in foreign currencies, primarily the Indian rupee, the euro, the SEK and the British pound. Revenue resulting from selling in local currencies and costs incurred in local currencies are exposed to foreign currency exchange rate fluctuations that can affect our operating income. As exchange rates vary, operating income may differ from expectations.

We may enter into foreign currency exchange forward contracts to reduce the impact of currency exchange rate movements on certain transactions from time to time, but do not cover all foreign-denominated transactions and therefore do not entirely eliminate the impact of fluctuations in exchange rates that could negatively affect our results of operations and financial condition. We also may enter into foreign currency exchange forward contracts to reduce the impact of foreign currency fluctuations on certain non-functional currency denominated account balances primarily in euros and British pounds from time to time. As a result, we do not expect a significant impact to our results from a change in exchange rates on foreign denominated non-functional account balances in the near-term. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate fluctuations on the underlying foreign currency denominated non-functional currency account balances. Accordingly, the effect of an immediate 10% adverse change in foreign exchange rates on these transactions during 2022 would not be material to our results of operations.

Interest Rate Risk

We had cash, cash equivalents and restricted cash totaling $189.2 million and $202.5 million as of December 31, 2022 and December 25, 2021, respectively. The unrestricted cash is held for working capital purposes. We do not enter into investments for speculative purposes. The effect of an immediate 10% adverse change in interest rates would not be material to our results of operations.

In September 2018, March 2020 and August 2022 we issued the 2024 Notes, 2027 Notes and the 2028 Notes, respectively. The 2024, 2027 and 2028 Notes have a fixed annual interest rate of 2.125%, 2.50% and 3.75%, respectively, and, therefore, we do not have economic interest rate exposure on the convertible senior notes. However, the fair values of the convertible senior notes are subject to interest rate risk, credit risk and other factors due to the convertible feature. The fair value of the convertible senior notes will generally increase as interest rates fall and decrease as interest rates rise. In addition, the fair value of the convertible senior notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines in value. The fair value of the convertible senior notes will generally increase as our credit worthiness improves and decrease when our creditworthiness weakens. The interest and market value changes affect the fair value of the convertible senior notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Additionally, we do not carry the convertible senior notes at fair value. We present the fair value for required disclosure purposes only. As of December 31, 2022, the fair value of the 2024, 2027 and 2028 Notes was $101.0 million, $221.4 million and $462.9 million, respectively. The fair value was determined based on the estimated fair value or quoted bid price as applicable of the 2024, 2027 and 2028 Notes in an over-the-counter market on December 30, 2022. The convertible senior notes are classified as Level 2 of the fair value hierarchy.

Holders may convert the convertible senior notes prior to maturity upon the occurrence of certain circumstances. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election (provided, however, that with respect to the 2028 Notes, we would be required to repay the principal amount in cash and the conversion premium in any combination of cash and shares of our common stock at our election). If our common stock price is above the initial conversion price of $9.87, $7.66 and $6.80 for the 2024, 2027 and 2028 Notes, respectively, upon conversion or at maturity, the amount of cash or shares of common stock required to pay the conversion premium is not fixed and would increase if our common stock price increases.

Report of Ernst & Young LLP, Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Infinera Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Infinera Corporation (the Company) as of December 31, 2022 and December 25, 2021, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and the financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and December 25, 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 27, 2023 expressed an unqualified opinion thereon.

Adoption of ASU No. 2020-06

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for convertible debt in the year ended December 31, 2022 due to the adoption of Accounting Standards Update ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.

Basis for Opinion

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

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

Critical Audit Matter

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

Inventory Valuation

Description of the Matter

At December 31, 2022, the Company’s inventory balance was $374.9 million and represented 22.5% of total assets. As discussed in Note 2 of the consolidated financial statements, the Company assesses the valuation of inventories, including raw materials, work-in-process, and finished goods, in each reporting period.

Obsolete inventory or inventory in excess of management’s forecasted demand is written down to its estimated net realizable value if less than cost.

Auditing management’s estimates for excess and obsolete inventory involved subjective auditor judgement because the estimates rely on a number of factors that are affected by market and economic conditions outside the Company’s control. In particular, the excess and obsolete inventory calculations are sensitive to significant assumptions, including forecasted demand for the Company’s products.

How We Addressed the

Matter in Our Audit

We obtained an understanding, evaluated the design, and tested the operating effectiveness of internal controls over the Company's excess and obsolete inventory reserve process. This included controls over management's assessment of the forecasted demand for their products and the completeness and accuracy of the data underlying the excess and obsolete inventory valuation.

Our audit procedures included, among others, evaluating the significant assumptions including forecasted demand and the accuracy and completeness of the underlying data management used to value excess and obsolete inventory. We compared the cost of on-hand inventories to customer demand forecasts and historical sales and evaluated adjustments to sales forecasts for specific product considerations, such as technological changes or alternative uses. We also assessed the historical accuracy of management's estimates and performed sensitivity analyses over the significant assumptions to evaluate the changes in the excess and obsolete inventory estimates that would result from changes in the underlying assumptions.

We have audited Infinera Corporation’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Infinera Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets as of December 31, 2022 and December 25, 2021, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and the financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”) and our report dated February 27, 2023 expressed an unqualified opinion thereon.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

Infinera Corporation (“Infinera” or the “Company”), headquartered in San Jose, California, was founded in December 2000 and incorporated in the State of Delaware. Infinera is a global supplier of networking solutions comprised of networking equipment, optical semiconductors, software and services. Infinera’s portfolio of solutions includes optical transport platforms, converged packet-optical transport platforms, optical line systems, disaggregated router platforms, and a suite of networking and automation software offerings, and support and professional services. Infinera leverages its U.S.-based compound semiconductor fab and in-house packaging capabilities to design, develop, and manufacture industry-leading indium phosphide-based photonic integrated circuits for use in its high-capacity optical communications products.

The Company operates and reports financial results on a fiscal year of 52 or 53 weeks ending on the last Saturday of December in each year. Accordingly, fiscal year 2022 was a 53-week year that ended on December 31, 2022. Fiscal years 2021 and 2020 were 52-week years that ended on December 25, 2021 and December 26, 2020, respectively. The next 53-week year will end on December 30, 2028.

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). The consolidated financial statements include all adjustments necessary for a fair presentation of the Company's annual results. All adjustments are of a normal recurring nature.

The consolidated financial statements include the accounts for the Company and its subsidiaries and affiliates in the Company which the Company has a controlling financial interest or is the primary beneficiary. All inter-company balances and transactions have been eliminated. The Company reclassified certain amounts reported in previous periods to conform to the current presentation.

2. Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. Estimates, assumptions and judgements made by management include inventory valuation, revenue recognition, accounting for income taxes, stock-based compensation, employee benefit and pension plans, manufacturing partner and supplier liabilities, allowances for sales returns, allowances for credit losses, useful life of intangibles and property, plant and equipment, impairment loss related to lease abandonment, accrued warranty, operating and finance lease liabilities, restructuring and other related costs and loss contingencies. The Company bases its assumptions on historical experience and also on assumptions that it believes are reasonable. Actual results could differ materially from those estimates. These estimates may change as new events occur and additional information emerges, and such changes are recognized or disclosed in the Company's consolidated financial statements.

Revenue Recognition

The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The Company determines revenue recognition by applying the following five-step approach:

•identification of the contract, or contracts, with a customer;

•identification of the performance obligations in the contract;

•determination of the transaction price;

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

•recognition of revenue when, or as, the Company satisfies a performance obligation.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Many of the Company's product sales are sold in combination with installation and deployment services along with initial hardware and software support. The Company's product sales are also sold at times with spares management, on-site hardware replacement services, network operations management, software subscription services, extended hardware warranty and training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription services include software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.

Spares management and on-site hardware replacement services include the replacement of defective units at customer sites in accordance with specified service level agreements. Network operations management includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. The Company evaluates each promised good and service in a contract to determine whether it represents a distinct performance obligation or should be accounted for as a combined performance obligation.

Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. The Company typically satisfies its performance obligations upon shipment or delivery of product depending on the contractual terms. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. The Company assesses its ability to collect from its customers based primarily on the creditworthiness and past payment history of the customer.

For sales to resellers, the same revenue recognition criteria apply. It is the Company’s practice to identify an end-user prior to shipment to a reseller. The Company does not offer rights of return or price protection to its resellers.

The Company reports revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Customer Purchase Commitments

The Company sells software licenses that provide customers the ability to purchase incremental bandwidth capacity on an already-deployed piece of hardware. Infinera Instant Bandwidth-enabled systems generally include a specific initial capacity and incremental capacity can be added by the purchase of Instant Bandwidth licenses. Instant Bandwidth licenses are considered distinct performance obligations because customers can provision additional transmission capacity on demand without the deployment of any incremental equipment.

Some contracts commit the customer to purchase incremental Instant Bandwidth licenses within a specified time frame from the initial shipment of the Instant Bandwidth-enabled hardware. The time frame varies by customer and generally ranges between 12 to 24 months. If the customer does not purchase the additional capacity within the time frame as stated in the contract, the Company has the right to deliver and invoice such Instant Bandwidth licenses to the customer. Future committed licenses are considered to be additional performance obligations when a minimum purchase obligation is present, as evidenced by enforceable rights and obligations. As such, the Company is required to estimate the variable consideration for future Instant Bandwidth licenses as part of determining the contract transaction price.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Variable Consideration

Stand-alone Selling Price

When allocating on a relative stand-alone selling price basis, any discount provided in the contract is generally allocated proportionately to all of the performance obligations in the contract.

The majority of products and services offered by the Company have readily observable selling prices. For products and services that do not, the Company generally estimates stand-alone selling price using the market assessment approach based on expected selling price and adjust those prices as necessary to reflect the Company’s costs and margins. As part of its stand-alone selling price policy, the Company reviews product pricing on a periodic basis to identify any significant changes and revise its expected stand-alone selling price assumptions as appropriate.

Shipping and Handling

The Company treats shipping and handling activities as costs to fulfill the Company's promise to transfer products. Shipping and handling fees billed to customers are recorded as a reduction to cost of product.

Capitalization of Costs to Obtain a Contract

The Company has assessed the treatment of costs to obtain or fulfill a contract with a customer. Sales commissions have historically been expensed as incurred. Under Topic 606, the Company capitalizes sales commissions related to multi-year service contracts, which are paid for upfront, and amortizes the asset over the period of benefit, which is the service period. Sales commissions paid on service contract renewals, are commensurate with the sales commissions paid on the initial contracts.

Transaction Price Allocated to the Remaining Performance Obligation

The Company’s remaining performance obligations represent the transaction price allocated to performance obligations that are unsatisfied or partially satisfied as of period end, consisting of deferred revenue and backlog. The Company’s backlog represents purchase orders received from customers for future product shipments and services that are unsatisfied or partially satisfied as of period end. The Company’s backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, may be canceled without penalty. Orders in backlog may be fulfilled several quarters following receipt or may relate to multi-year support service obligations.

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period (generally the vesting period) under the straight-line amortization method. The Company accounts for forfeitures as they occur.

The Company estimates the fair value of the rights to acquire stock under its 2007 Employee Stock Purchase Plan (the “ESPP”) using the Black-Scholes option pricing formula. The ESPP provides for consecutive six-month offering periods and the Company's historical volatility data in the valuation of shares that are purchased under the ESPP.

The Company accounts for the fair value of restricted stock units (“RSUs”) using the closing market price of the Company’s common stock on the date of grant. For new-hire grants, RSUs typically vest ratably on an annual basis over four years. For annual refresh grants, RSUs typically vest ratably over 18 months to three years.

Performance Stock Units ("PSUs") granted to the Company's executive officers and senior management during 2019, 2020, 2021 and 2022 are based on performance criteria related to specific financial targets over the span of a two or three-year performance period. These PSUs may become eligible for vesting to begin before the end of the applicable performance period, if the applicable financial target is met. The number of shares to be issued upon vesting of these PSUs is capped at the target number of PSUs granted. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.

In addition, the Company granted other PSUs to certain employees that only vest upon the achievement of specific operational performance criteria. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.

Employee Benefit and Pension Plans

The Company operates a number of post-employment plans in Germany, as well as smaller post-employment plans in other countries, including both defined contribution and defined benefit plans. Benefit cost and obligations pertaining to these plans are based on assumptions for the discount rate, expected return on plan assets, mortality rates, expected salary increases, health care cost trend rates and attrition rates. The discount rate assumption is based on current investment yields of high-quality fixed-income securities with maturities similar to the expected benefits payment period. Mortality rates help predict the expected life of plan participants. The expected increase in the compensation levels assumption reflects the Company's actual experience and future expectations. The expected long-term return on plan assets is determined based on asset allocations, historical portfolio results, historical asset correlations and management’s expected returns for each asset class. The Company evaluates its expected return assumptions annually including reviewing current capital market assumptions to assess the reasonableness of the expected long-term return on plan assets. The Company updates the expected long-term return on assets when the Company observes a sufficient level of evidence that would suggest the long-term expected return has changed.

Research and Development

All costs to develop the Company’s hardware products are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s software products are released soon after technological feasibility has been established. As a result, costs subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.

Advertising

All advertising costs are expensed as incurred. Advertising expenses in 2022, 2021 and 2020 were $1.5 million, $1.6 million, and $1.3 million, respectively.

Accounting for Income Taxes

As part of the process of preparing its consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in consolidated statements of operations become deductible expenses under applicable income tax laws or loss, or credit carryforwards are utilized. Accordingly, realization of deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.

The Company must assess the likelihood that some portion or all of its deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent the Company believes that recovery does not meet the “more-likely-than-not” standard, it must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities and any valuation allowance

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

recorded against our net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including the Company's forecast of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors. Based on the available objective evidence, at December 31, 2022, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.

During 2022, the Company executed an internal realignment of its supply chain and customer-facing entities. Among other things, the new structure aligned and consolidated the exploitation of its intellectual property and the allocation of the associated commercial risk and reward with the customer-facing entities that manage its supply chain. The impact of this internal realignment is reflected in the Company’s tax provision for the year ended December 31, 2022.

Foreign Currency Translation and Transactions

The Company considers the functional currencies of its foreign subsidiaries to be the local currency. Assets and liabilities recorded in foreign currencies are translated at the exchange rate as of the balance sheet date, revenue, costs and expenses are translated at average exchange rates in effect during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets and consolidated statements of comprehensive income (loss).

For all non-functional currency account balances, the re-measurement of such balances to the functional currency will result in either a foreign exchange transaction gain or loss, which is recorded to other income (loss), net, in the Company's consolidated statement of operations, in the same period that the re-measurement occurred. Aggregate foreign exchange transactions recorded was gain of $12.8 million in 2022 and losses of $17.2 million and $0.2 million, in 2021 and 2020, respectively.

The Company enters into foreign currency exchange forward contracts to reduce the impact of foreign exchange fluctuations on earnings from certain non-functional currency account balances denominated primarily in euros and British pounds.

Cash and Cash Equivalents

Cash consists primarily of cash in bank deposit accounts which, at times, a portion may exceed federally insured limits. The Company has not experienced any losses in such accounts.

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Fair Value Measurement

Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Valuation techniques used by the Company are based upon observable and unobservable inputs. Observable or market inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about market participant assumptions based on the best information available. Observable inputs are the preferred source of values. These two types of inputs create the following fair value hierarchy:

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Level 1

–

Quoted prices in active markets for identical assets or liabilities.

Level 2

–

Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3

–

Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

The Company measures its cash equivalents, foreign currency exchange forward contracts and debt securities at fair value and classifies them in accordance with the fair value hierarchy on a recurring basis.

Foreign Currency Exchange Forward Contracts

As discussed in Note 6, “Derivative Instruments" to the Notes to Consolidated Financial Statements, the Company historically held non-speculative foreign exchange forward contracts to hedge certain foreign currency exchange exposures. The Company estimates the fair values of derivatives based on quoted market prices or pricing models using current market rates. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies.

Facilities-related Charges

The Company estimates the fair value of its facilities-related charges associated with its restructuring plans, based on estimated future discounted cash flows and unobservable inputs, which includes the amount and timing of estimated sublease rental receipts that the Company can reasonably obtain over the remaining lease term and the discount rate.

Accounts Receivable and Allowances for Credit Losses

Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for estimated credit losses resulting from the inability of its customers to make required payments and reviewed the allowance quarterly. The Company determines expected credit losses by performing credit evaluations of its customers' financial condition, establishing both a general reserve and specific reserve for customers in adverse financial condition and adjusting for its expectations of changes in conditions that may impact the collectability of outstanding receivables. The Company considers a customer's receivable balance past due when the amount is due beyond the credit terms extended, The Company considers factors such as historical experience, credit quality, age of the accounts receivable balances, and geographic or country-specific risks. Amounts are written off when receivables are determined to be uncollectible.

Allowances for Sales Returns

Customer product returns are approved on a case by case basis. Specific reserve provisions are made based upon a specific review of all the approved product returns where the customer has yet to return the products to generate the related sales return credit at the end of a period. Estimated sales returns are provided for as a reduction to revenue. At December 31, 2022, December 25, 2021 and December 26, 2020, revenue was reduced for estimated sales returns by $3.6 million, $0.8 million, and $2.4 million, respectively.

Concentration of Risk

Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents and restricted cash, foreign exchange contracts and accounts receivable.

The risk with respect to foreign exchange contracts is mitigated by entering into these contracts with a large high-quality financial institution and the Company monitors the creditworthiness of the counterparty consistently.

The risk with respect to accounts receivable is mitigated by ongoing credit evaluations that the Company performs on its customers. As the Company continues to expand its sales internationally, it may experience increased levels of customer credit risk associated with those regions. Collateral is generally not required for accounts receivable but may be used in the future to mitigate credit risk associated with customers located in certain geographical regions.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

One customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 31, 2022. No customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 25, 2021.

One customer accounted for approximately 11% of the Company's revenue in 2022 and 2020. No customer accounted for 10% or more of the Company's revenue in 2021.

The Company depends on sole source or limited source suppliers for several key components and raw materials. The Company generally purchases these sole source or limited source components and raw materials through standard purchase orders and does not have long-term contracts with many of these limited-source suppliers. While the Company seeks to maintain sufficient reserve stock of such components and raw materials, the Company’s business and results of operations could be adversely affected if any of its sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output.

Derivative Instruments

The Company is exposed to foreign currency exchange rate fluctuations in the normal course of its business. As part of its risk management strategy, the Company uses derivative instruments, specifically forward contracts, to reduce the impact of foreign exchange fluctuations on earnings. The forward contracts are with high-quality institutions and the Company monitors the creditworthiness of the counterparties consistently. The Company’s objective is to offset gains and losses resulting from these exposures with gains and losses on the derivative contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets. The Company does not use derivative contracts for trading or speculative purposes.

The Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuations in foreign exchange rates that arise primarily from euro and British pounds. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate changes on the underlying account balances, and therefore, do not subject the Company to material balance sheet risk.

The Company has entered into factoring agreements, to sell certain receivables to unrelated third-party financial institutions. These transactions are accounted for in accordance with ASC 860, Transfers and Servicing (“ASC 860”). ASC 860 and result in a reduction in accounts receivable because the agreements transfer effective control over and risk related to the receivables to the buyers. The Company's factoring agreements do not allow for recourse in the event of uncollectability, and the Company does not retain any interest in the underlying accounts receivable once sold.

Inventory Valuation

Inventory that is obsolete or in excess of the Company’s forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing its inventory costs and deferred inventory costs, the Company considered whether the net realizable value of inventory delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. The Company concluded that, in the instances where the net realizable value of inventory delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at cost or net realizable value, whichever is lower, thereby recognizing the cost of the reduction in net realizable value of inventory in the period in which the reduction occurred or can be reasonably estimated. The Company has, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of actual cost or net realizable value.

The Company considers whether it should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contractual purchase price, the Company has also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Property, Plant and Equipment

Property, plant and equipment are stated at cost. This includes enterprise-level business software that the Company customizes to meet its specific operational needs and certain software licenses. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. An assumption of lease renewal where a renewal option exists is used only when the renewal has been determined to be reasonably certain. Repair and maintenance costs are expensed as incurred. The estimated useful life for each asset category is as follows:


			Estimated Useful Lives
Building			20 years
Laboratory and manufacturing equipment			1.5 to 10 years
Furniture and fixtures			3 to 5 years
Computer hardware			3 to 5 years
Computer software			3 years
Leasehold and building improvements			1 to 11 years

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable or that the useful life is shorter than originally estimated. If impairment indicators are present and the projected future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. If assets are determined to be recoverable, but the useful lives are shorter than originally estimated, the carrying value of the assets is depreciated over the newly determined remaining useful lives.

Accrued Warranty

In the Company's contracts with its customers, the Company warrants that its products will operate substantially in conformity with product specifications. Hardware warranties provide the purchaser with protection in the event that the product does not perform to product specifications. During the warranty period, the purchaser’s sole and exclusive remedy in the event of such defect or failure to perform is limited to the correction of the defect or failure by repair, refurbishment or replacement, at the Company’s sole option and expense. The Company's hardware warranty periods generally range from one to five years from date of acceptance for hardware and the Company's software warranty is 90 days. Upon delivery of the Company's products, the Company provides for the estimated cost to repair or replace products that may be returned under warranty. The hardware warranty accrual is based on actual historical returns and cost of repair experience and the application of those historical rates to the Company's in-warranty installed base. The provision for warranty claims fluctuates depending upon the installed base of products and the failure rates and costs of repair associated with these products under warranty. Furthermore, the Company's costs of repair vary based on repair volume and its ability to repair, rather than replace, defective units. In the event that actual product failure rates and costs to repair differ from the Company's estimates, revisions to the warranty provision are required. In addition, from time to time, specific hardware warranty accruals may be made if unforeseen technical problems arise with specific products. The Company regularly assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Amortization of Intangible Assets

Intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. In-process research and development represent the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization, but once projects have been completed, these assets are transferred to developed technology, which are subject to amortization, while assets related to projects that have been abandoned are impaired and expensed to research and development.

Impairment of Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price of an acquired business over the fair value of the identifiable assets acquired and liabilities assumed. The Company tests for impairment of goodwill on an annual

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

basis in the fourth quarter and at any other time when events occur or circumstances indicate that the carrying amount of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines that as a result of the qualitative assessment that it is more likely than not (i.e., greater than 50% likelihood) that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is required or it can directly perform the quantitative analysis. The Company recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized does not exceed the total amount of goodwill allocated to that reporting unit.

The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of these assets by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, the Company records an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Leases

The Company has operating leases primarily for real estate (facilities) and automobiles. The Company has finance leases primarily for computer hardware, laboratory and manufacturing equipment and leasehold and building improvements.

The Company leases facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 11 years and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to six years.

The Company determines if an arrangement contains a lease at inception. Operating leases are included in operating lease right of use ("ROU") assets, accrued expenses and other current liabilities and operating lease liabilities on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, net, accrued expenses and other current liabilities and other long-term liabilities on the Company's consolidated balance sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. Operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. Variable lease payments are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company rents or subleases certain real estate under agreements that are classified as operating leases.

Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company does not account for lease components (e.g., fixed payments including rent) separately from the non-lease components (e.g., common-area maintenance costs).

Upon abandoning or committing to a plan to abandon a leased property in the short term before the lease term expires, the Company assesses the fair value of its remaining obligation under the lease and records an impairment of the ROU asset, if needed. The impairment loss is calculated as the present value of the amount by which the remaining lease obligation, adjusted for the effects of any one-time costs to sublease, exceeds the estimated sublease rentals that could be reasonably obtained. The estimated sublease rentals consider Company's ability and intent to sublease the space. The significant assumptions used in the Company's discounted cash flow model include the amount and timing of estimated sublease rental receipts and the discount rate which involve a number of risks and uncertainties, some of which are beyond control, including future real estate market conditions and the Company's ability to successfully enter into subleases or termination agreements with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The loss recorded or to be recorded may change significantly as a result of the re-measurement of the liability, if the timing or amount of estimated cash flows change.

Restructuring and Other Related Costs

The Company records costs associated with exit activities related to restructuring plans in accordance with ASC 420, Exit or Disposal Cost Obligations, or ASC 712, Compensation — Nonretirement Postemployment Benefits. Liabilities for costs associated with an exit or disposal activity are recognized in the period in which the liability is incurred. The timing of the associated cash payments is dependent upon the type of exit cost and extends over an approximately four-year period. The Company records restructuring cost liabilities in “accrued expenses and other current liabilities” and "other long-term liabilities" in the consolidated balance sheet.

Restructuring costs include employee and contract termination costs, facility consolidation and closure costs, lease related impairment charges, equipment write-downs and inventory write-downs. One-time termination benefits are recognized as a liability at estimated fair value when the approved plan of termination has been communicated to employees, unless employees must provide future service, in which case the benefits are recognized ratably over the future service period. Ongoing termination benefits arrangements are recognized as a liability at estimated fair value when the amount of such benefits becomes estimable and payment is probable.

Restructuring charges require significant estimates and assumptions, including estimates made for employee separation costs and other contract termination charges. Management estimates involve a number of risks and uncertainties, some of which are beyond control, including the Company's ability to successfully enter into termination agreements with employees and others with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.

Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for convertible instruments by removing certain separation models in ASC 470-20, Debt—Debt with Conversion and Other Options, for convertible instruments. On December 26, 2021, the Company adopted ASU 2020-06 using the modified retrospective method. Applying the transition guidance, the Company was required to apply the guidance to all impacted financial instruments that were outstanding as of December 26, 2021 with the cumulative effect recognized as an adjustment to the opening balance of accumulated deficit.

The adoption of ASU 2020-06 required the Company to record a $196.5 million reduction of additional paid in capital, on December 26, 2021, due to the recombination of the equity conversion component of convertible debt remaining outstanding, which was initially separated and recorded in equity. The $122.0 million increase in debt represented the removal of the remaining debt discounts recorded for this previous separation. The Company recognized a $74.5 million cumulative effect decrease of initially applying ASU 2020-06 as an adjustment to the December 26, 2021 opening balance of accumulated deficit. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible senior notes as a liability instrument. Since the Company had a net loss in 2022, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share in 2022 as a result of adopting ASU 2020-06. The prior period consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods.

3. Leases

The Company has operating leases for real estate (facilities) and automobiles. For the fiscal years ended December 31, 2022, December 25, 2021 and December 26, 2020, operating lease expense was $21.1 million, $25.7 million and $34.0 million, respectively.

Disclosure of Fair Values

Financial instruments that are not re-measured at fair value include accounts receivable, accounts payable, accrued liabilities, and debt. The carrying values of these financial instruments other than the Company's 2024 Notes, 2027 Notes and 2028 Notes (collectively referred to as "convertible senior notes" below) approximate their fair values. The fair value of each series of convertible senior notes was determined based on the quoted bid price of the applicable series of convertible senior notes in an over-the-counter market on December 30, 2022 (the last trading day of the fiscal quarter).

The following table presents the estimated fair values of the convertible senior notes (in thousands):


	As of December 31, 2022						As of December 25, 2021
	Fair Value Measured Using						Fair Value Measured Using

Convertible senior notes	$	—	$	785,364	$	785,364	$	—	$	765,412	$	765,412

Cash equivalents are measured and reported at fair value on a recurring basis. The following table presents the fair value of these financial assets and their levels within the fair value hierarchy (in thousands):


	As of December 31, 2022						As of December 25, 2021

Money market funds	$	95,000	$	—	$	95,000	$	—	$	—	$	—

During 2022 and 2021, there were no transfers of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy. As of December 31, 2022 and December 25, 2021, none of the Company’s existing securities were classified as Level 3 securities.

The Company measures goodwill and intangible assets at fair value on a nonrecurring basis when there are identifiable events or changes in circumstances that may have a significant adverse impact on the fair value of these assets. The Company performed an analysis of impairment indicators of these assets and noted no adverse impact to their fair values as of December 31, 2022.

Facilities-related Charges

The Company classifies certain facilities-related charges within Level 3 of the fair value hierarchy and applies fair value accounting on a nonrecurring basis when impairment indicators exist or upon the existence of observable fair values. The fair values are classified as Level 3 measurements due to the significance of unobservable inputs. These analyses require management to make assumptions and estimates regarding industry and economic factors, future operating results and discount rates.

In connection with its Restructuring Plans (as defined in Note 9, “Restructuring and Other Related Costs” to the Notes to Consolidated Financial Statements), the Company incurred facilities related charges of

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

$8.1 million and $6.5 million for the years ended December 31, 2022 and December 25, 2021, respectively. These charges primarily consisted of impairment charges incurred for operating lease right-of-use assets and were calculated at fair value based on estimated future sublease rental receipts that the Company could reasonably obtain over the remaining lease term at the discount rate. Facilities-related charges are classified as Level 3 measurement due to the significance of these unobservable inputs.

Cash and Cash Equivalents

As of December 31, 2022, the Company had $189.2 million of cash, cash equivalents and restricted cash, including $65.9 million held by its foreign subsidiaries. As of December 25, 2021, the Company had $202.5 million of cash, cash equivalents and restricted cash including $77.6 million held by its foreign subsidiaries. The Company's cash held by its foreign subsidiaries is used for operating and investing activities in those locations, and the Company does not currently have the need or the intent to repatriate those funds to the United States.

6. Derivative Instruments

Foreign Currency Exchange Forward Contracts

The Company transacts business in various foreign currencies and has international sales, cost of sales, and expenses denominated in foreign currencies, and carries foreign-currency-denominated account balances, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company utilizes foreign currency forward contracts, primarily short term in nature.

Historically, the Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuation in foreign exchange rates that arise from its euro and British pound denominated account balances. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate fluctuations on the underlying foreign currency denominated account balances, do not subject the Company to material balance sheet risk.

The Company had no outstanding foreign currency exchange forward contracts as of December 31, 2022. As of December 25, 2021, the Company had $29.5 million outstanding foreign currency exchange forward contract and posted collateral of $0.9 million to cover associated potential credit risk exposure. This collateral amount was classified as other long-term restricted cash on the accompanying consolidated balance sheets.

The before-tax effect of foreign currency exchange forward contracts was a gain of $0.6 million, $0.9 million and $0.3 million for 2022, 2021 and 2020, respectively, included in other income (expense), net, in the consolidated statements of operations. In each of these periods, the impact of the gross gains and losses were offset by foreign exchange rate fluctuations on the underlying foreign currency denominated amounts.

The Company does not designate foreign currency exchange forward contracts as hedges for accounting purposes and accordingly, changes in the fair value are recorded in the accompanying consolidated statements of operations. These contracts were with one high-quality institution and the Company consistently monitors the creditworthiness of the counterparties.

Accounts Receivable Factoring

The Company sells certain designated trade account receivables based on factoring arrangements with well-established factoring companies. Pursuant to the terms of the arrangements, the Company accounts for these transactions in accordance with ASC 860. The Company's factor purchases trade accounts receivables on a non-recourse basis and without any further obligations. Trade accounts receivables balances sold are removed from the consolidated balance sheets and cash received are reflected as cash provided by operating activities in the consolidated statements of cash flow. The difference between the fair value of the Company's trade receivables and the proceeds received is recorded as interest expense in the Company's consolidated statements of operations. For the years ended December 31, 2022, December 25, 2021 and December 26, 2020, the Company's recognized factoring related interest expense was approximately $0.9 million, $0.4 million and $0.4 million, respectively. The gross amount of trade accounts receivables sold totaled approximately $101.0 million and $121.3 million for the fiscal years ended December 31, 2022 and December 25, 2021 respectively.

7. Goodwill and Intangible Assets

Goodwill

Goodwill is recorded when the purchase price of an acquisition exceeds the fair value of the net tangible and identified intangible assets acquired.

The following table presents details of the Company’s goodwill for the fiscal year ended December 31, 2022 (in thousands):


Balance as of December 25, 2021	$	255,788

9. Restructuring and Other Related Costs

In 2020, the Company implemented a restructuring initiative (the "2020 Restructuring Plan") that was primarily intended to reduce costs and consolidate its operations. The identified cost reduction initiatives under the 2020 Restructuring Plan were substantially completed, with the majority of associated payments made in 2020 and the remaining amounts substantially paid during 2021.

In 2021, the Company announced a plan to restructure certain international research & development operations (the "2021 Restructuring Plan"). The Company estimates it will incur total costs related to the restructuring ranging from $15.0 million to $17.0 million, of which $6.1 million and $8.5 million was recorded in

INFINERA CORPORATION

11. Basic and Diluted Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using net loss and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the assumed exercise of outstanding in-the-money stock options, assumed release of outstanding RSUs and PSUs, and assumed issuance of common stock under the ESPP using the treasury stock method. Potentially dilutive common shares also include the shares of common stock issuable upon conversion of the convertible senior notes using the if-converted method, as further discussed in Note 12, “Debt” to the Notes to Consolidated Financial Statements. The Company includes the common shares underlying PSUs in the calculation of diluted net income per common share only when they become contingently issuable.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The following table sets forth the computation of net loss per common share (in thousands, except per share amounts):


	Years Ended

Net loss	$	(76,043)	$	(170,778)	$	(206,723)

Weighted average common shares outstanding - basic and diluted	216,376		207,377		188,216





Net loss per common share - basic and diluted	$	(0.35)	$	(0.82)	$	(1.10)

The Company incurred net losses during 2022, 2021 and 2020, and as a result, potential common shares from stock options, RSUs, PSUs and the assumed release of outstanding shares under the ESPP were not included in the diluted shares used to calculate net loss per share, as their inclusion would have been anti-dilutive. Additionally, due to the net loss position during these periods, the Company excluded the potential shares issuable upon conversion of the 2028 Notes, the 2027 Notes and the 2024 Notes in the calculation of diluted earnings per share, as their inclusion would have been anti-dilutive.

The following table sets forth the potentially dilutive shares excluded from the computation of the diluted net loss per share because their effect was anti-dilutive (in thousands):


	As of
	December 31, 2022	December 25, 2021	December 26, 2020
Convertible senior notes(1)	55,800	4,448	8
Stock options outstanding	—	—	451
Restricted stock units	14,836	12,860	13,947
Performance stock units	2,685	2,751	3,668
Employee stock purchase plan shares	360	1,157	1,713
Total	73,681	21,216	19,787

(1) The convertible senior notes were calculated under the if-converted method for 2022 due to the adoption of ASU 2020-06 and under the treasury stock method for 2021 and 2020.

Prior to the adoption of ASU 2020-06, the Company used the treasury stock method for calculating any potential dilutive effect of the conversion spread of its convertible senior notes. The conversion spread had a dilutive impact for the 2027 Notes during the fiscal year ended December 25, 2021 since the average market price of the Company’s common stock during the periods exceeded the initial conversion price of $7.66 per share. However, the potential shares of common stock issuable upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive.

After the adoption of ASU 2020-06, the Company used the if-converted method for calculating any potential dilutive effect of the convertible senior notes for fiscal year ended December 31, 2022. The Company calculates diluted earnings per share assuming that all of the convertible senior notes permitted to be share settled were converted solely into shares of common stock at the beginning of the reporting period. The potential impact upon the conversion of the convertible senior notes was excluded from the calculation of diluted net loss per share for the fiscal year ended December 31, 2022 because the effect would have been anti-dilutive.

Convertible Senior Notes

In September 2018, the Company issued $402.5 million aggregate principal amount of 2.125% Convertible Senior Notes due 2024 (the "2024 Notes"). In March 2020, the Company issued $200.0 million aggregate principal amount of 2.5% Convertible Senior Notes due 2027 (the “2027 Notes"). In August 2022, the Company issued $373.8 million aggregate principal amount of 3.75% Convertible Senior Notes due 2028 (the "2028 Notes," and, together with the 2024 Notes and 2027 Notes, the “convertible senior notes”). The 2024 Notes bear interest at a fixed rate of 2.125% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2019. The 2027 Notes bear interest at a fixed rate of 2.5% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2020. The 2028 Notes bear interest at a fixed rate of 3.75% per year, payable semi-annually in arrears on February 1 and August 1 of each year, beginning on February 1, 2023. Each series of the convertible senior notes is governed by an indenture between the Company, as the issuer, and U.S. Bank National Association, as Trustee (individually, each an “Indenture,” and together, the “Indentures”). The convertible senior notes of each series are unsecured and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the convertible senior notes; equal in right of payment to any of the Company's existing and future liabilities that are not so subordinated, effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s current or future subsidiaries. The applicable Indenture governing each series of the convertible senior notes does not contain any financial covenants or any restrictions on the payment of dividends, the incurrence of senior debt or other indebtedness, or the issuance or repurchase of the Company's other securities by the Company.

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The net proceeds to the Company from the issuance of 2024 Notes were approximately $391.4 million, of which approximately $48.9 million was used to pay the cost of the capped call transactions with certain financial institutions (“Capped Calls”). The Company also used a portion of the remaining net proceeds to fund the cash portion of the purchase price of the Acquisition, including fees and expenses relating thereto, and used the remaining net proceeds for general corporate purposes.

The Capped Calls have an initial strike price of $9.87 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2024 Notes. The Capped Calls have initial cap prices of $15.19 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, 40.8 million shares of common stock. The Capped Calls transactions are expected generally to reduce or offset potential dilution to the Company's common stock upon any conversion of the 2024 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2024 Notes, as the case may be, with such reduction and/or offset subject to a cap. The Capped Calls expire on various dates between July 5, 2024 and August 29, 2024. The Capped Calls were recorded as a reduction of the Company’s stockholders’ equity in the accompanying consolidated balance sheets.

The net proceeds to the Company from the issuance of 2027 Notes were approximately $193.3 million after deducting initial purchasers' fee and other debt issuance costs. The Company used the remaining net proceeds for general corporate purposes, including working capital to fund growth and potential strategic projects.

The net proceeds to the Company from the issuance of 2028 Notes were approximately $362.4 million after deducting the initial purchasers' fee and other debt issuance costs. The Company used approximately $283.6 million, which included accrued and unpaid interest, of the net proceeds from this issuance to repurchase approximately $299.8 million in aggregate principal amount of its 2024 Notes concurrently with the issuance. This transaction involved a contemporaneous exchange of cash between the Company and holders of the 2024 Notes participating in the issuance of the 2028 Notes. Accordingly, the transaction was evaluated for modification or extinguishment accounting in accordance with ASC 470-50, Debt – Modifications and Extinguishments on a creditor-by creditor basis depending on whether the exchange was determined to have substantially different terms. The repurchase of the 2024 Notes and issuance of the 2028 Notes were deemed to have substantially different terms based on the present value of the cash flows or significant difference between the value of the conversion option immediately prior to and after the exchange. Therefore, the repurchase of the 2024 Notes was accounted for as a debt extinguishment. The Company recorded a $15.5 million gain on extinguishment of debt on its consolidated statements of operations during the fiscal year ended December 31, 2022, which includes the write-off of related deferred issuance costs of $3.5 million. After giving effect to the repurchase, the total remaining principal amount outstanding under the 2024 Notes as of December 31, 2022 was $102.7 million.

The Company intends to use the remaining net proceeds from the issuance of 2028 Notes for general corporate purposes, including working capital and to fund growth and potential strategic projects.

The 2024 Notes, the 2027 Notes and the 2028 Notes mature on September 1, 2024, March 1, 2027 and August 1, 2028, respectively. The Company did not have the right to redeem the 2024 Notes prior to September 5, 2021, and may not redeem the 2027 Notes prior to March 5, 2024 or the 2028 Notes prior to August 5, 2025. The Company may redeem for cash all or any portion of the 2024 Notes at its option, on or after September 5, 2021, the 2027 Notes, at its option, on or after March 5, 2024, and the 2028 Notes, at its option, on or after August 5, 2025, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the convertible senior notes.

Conversion Rate and Initial Conversion Price for each series of convertible senior notes are presented in the following table:

INFINERA CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)


	Conversion Rate per $1,000 Principal	Initial Conversion Price
2024 Notes	101.2812	$	9.87
2027 Notes	130.5995	$	7.66
2028 Notes	147.1183	$	6.80

Throughout the term of the convertible senior notes, the conversion rate may be adjusted upon the occurrence of certain events, including for any cash dividends. Holders of the convertible senior notes will not receive any cash payment representing accrued and unpaid interest upon conversion. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than canceled, extinguished or forfeited. Prior to the close of business on the business day immediately preceding June 1, 2024 for the 2024 Notes, December 1, 2026 for the 2027 Notes and May 1, 2028 for the 2028 Notes (the convertible dates), holders may convert their convertible senior notes under the following circumstances:

•during any fiscal quarter commencing after the fiscal quarters ended on December 29, 2018 for the 2024 Notes, June 27, 2020 for the 2027 Notes and September 24, 2022 for the 2028 Notes (and only during such fiscal quarter) if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the convertible senior notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls any or all of the convertible senior notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date;

•upon the occurrence of specified corporate events described under the Indentures, such as a consolidation, merger or binding share exchange;

•or at any time on or after respective convertible dates, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their convertible senior notes at any time, regardless of the foregoing circumstances.

Upon the receipt of conversion requests, the settlement of the convertible senior notes will be paid pursuant to the terms of the respective governing Indentures. In the event that any of the 2024 Notes and 2027 Notes are converted, the Company would be required to repay the principal amount and any conversion premium in any combination of cash and shares of its common stock at the Company’s option. In the event that any of the 2028 Notes are converted, the Company would be required to repay the principal amount in cash and the conversion premium in any combination of cash and shares of its common stock at the Company’s option.

If the Company undergoes a fundamental change as defined in the Indentures, holders may require the Company to repurchase for cash all or any portion of their convertible senior notes at a repurchase price equal to 100% of the principal amount of the convertible senior notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, upon the occurrence of a “make-whole fundamental change” (as defined in each of the Indentures), the Company may, in certain circumstances, be required to increase the conversion rate by a number of additional shares for a holder that elects to convert its convertible senior notes in connection with such make-whole fundamental change.

There have been no changes to the initial conversion price of the convertible senior notes since issuance. None of the conditions allowing holders of the convertible senior notes to convert early were met. The convertible senior notes were therefore not convertible during 2022.

Adoption of ASU 2020-06

Prior to the adoption of ASU 2020-06 on December 26, 2021 and in accounting for the issuance of the convertible senior notes, the convertible senior notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The carrying amounts of the equity component representing the conversion option related to the 2024 Notes and 2027 Notes were $128.7 million and $67.8 million, respectively. This was determined by deducting the fair value of the liability component from its par value. The equity component was recorded in additional paid-in-capital and was not re-measured as long as it continued to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the “debt discount”) was amortized to interest expense over the respective contractual term of the convertible senior notes at an effective interest rate of 9.92%.

Prior to the adoption of ASU 2020-06 on December 26, 2021 and in accounting for the debt issuance costs of $12.9 million and $6.7 million related to the 2024 Notes and 2027 Notes, respectively, the Company allocated the total amount incurred to the liability and equity components of the convertible senior notes based on their relative values. Issuance costs attributable to the liability component were $8.7 million and $4.3 million, related to the 2024 Notes and 2027 Notes, respectively, and were amortized to interest expense using the effective interest method over the contractual term of the convertible senior notes. Issuance costs attributable to the equity component were netted with the equity component in additional paid-in-capital.

On December 26, 2021, the Company adopted ASU 2020-06 based on a modified retrospective transition method. Under such transition, prior-period information has not been retrospectively adjusted.

In accounting for the convertible senior notes after adoption of ASU 2020-06, the convertible senior notes are accounted for as a single liability. The issuance cost related to the 2024 Notes, the 2027 Notes and the 2028 Notes are being amortized to interest expense over the respective contractual term, at effective interest rates of 2.7%, 3.0% and 4.3%, respectively. Unamortized debt issuance costs will be amortized over the remaining life of the 2024 Notes, the 2027 Notes and the 2028 Notes which is approximately 20 months, 50 months, and 67 months, respectively.

Asset-based revolving credit facility

On June 24, 2022, the Company entered into a Loan, Guaranty and Security Agreement (the “Loan Agreement”) with the lenders party thereto, and Bank of America, N.A., as agent. The Loan Agreement provides for a senior secured asset-based revolving credit facility of up to $200 million (the "Credit Facility"), which the Company may draw upon from time to time. The Company may increase the total commitments under the revolving credit facility by up to an additional $100 million, subject to certain conditions. In addition, the Loan Agreement provides for a $50 million letter of credit subfacility and a $20 million swingline loan facility.

The proceeds of the loans under the Loan Agreement may be used to pay the fees, costs, and expenses incurred in connection with the Loan Agreement, repay existing debt and for working capital and general corporate purposes, including to fund growth. The Credit Facility has a stated maturity date of June 24, 2027. Availability under the Credit Facility will be based upon periodic borrowing base certifications valuing certain inventory and accounts receivable, as reduced by certain reserves. The Credit Facility is secured by a first-priority security interest (subject to certain exceptions) in inventory, certain related assets, specified deposit accounts, and certain other accounts.

Outstanding borrowings accrue interest at floating rates plus an applicable margin of 1.25% to 1.75% for Term Secured Overnight Financing Rate ("SOFR") rate loans and 0.25% to 0.75% for base rate loans. The unused line fee rate payable on the unused portion of the Credit Facility is equal to 0.25% per annum based on utilization of the Credit Facility.

The Loan Agreement contains customary affirmative covenants, such as financial statement reporting requirements and delivery of borrowing base certificates. The Loan Agreement also contains customary covenants that limit the ability of the Company to, among other things, incur debt, create liens and encumbrances, engage in certain fundamental changes, dispose of assets, prepay certain indebtedness, make restricted payments, make investments, and engage in transactions with affiliates. The Loan Agreement also contains a financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio. As of December 31, 2022, the Company was in compliance with all covenants under the Loan Agreement.

In connection with the Credit Facility, the Company incurred lender and other third-party costs of approximately $1.2 million, which are recorded as a deferred asset and will be amortized to interest expense using a straight-line method over the term of the Credit Facility.

As of December 31, 2022, the Company had availability of $161.6 million under the Credit Facility. As of December 31, 2022, the Loan Agreement included a $50.0 million letter of credit subfacility and $15.4 million letters of credit issued and outstanding.

On August 1, 2019, the Company entered into a Credit Agreement with Wells Fargo Bank, N.A., (the "2019 Credit Agreement"), which was subsequently amended on December 23, 2019 (the "Amended Credit Agreement", and together with the 2019 Credit Agreement, the "Prior Credit Agreement"). The Prior Credit Agreement provided for a senior secured asset-based revolving credit facility of up to $150 million, which the Company could draw upon from time to time. The credit facility was secured by first-priority security interest

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(subject to certain exceptions) in inventory, certain related assets, specified deposit accounts, and certain other accounts in certain domestic subsidiaries. The Prior Credit Agreement also provided for a $50 million letter of credit sub-facility and a $10 million swing loan sub-facility.

Outstanding borrowings under the Prior Credit Agreement accrued interest at floating rates plus and applicable margin from 2.00% to 2.50% for LIBOR rate loans and 1.00% to 1.50% for base rate loans, depending on the utilization of the credit facility. The commitment fee payable on the unused portion of the credit facility ranged from 0.375% to 0.625% per annum, also based on the utilization of the credit facility. The letter of credit accrued fee at a per annum rate equal to the applicable LIBOR rate margin times by the average amount of the letter of credit usage during the immediately preceding quarter, in addition to the fronting fees, commissions and other fees.

Effective January 1, 2022, with the cessation of LIBOR, the Prior Credit Agreement provided for an alternative benchmark rate for LIBOR-based loans, which included SOFR or other prevailing market rate as determined by the agent plus a spread based on prevailing market convention for the applicable interest period plus a margin ranging from 2.00% to 2.50%.

The Prior Credit Agreement contained customary affirmative covenants, such as financial statement reporting requirements and delivery of borrowing base certificates. It also contained customary covenants that limited the ability of the Company and its subsidiaries to, among other things, incur debt, create liens and encumbrances, engage in certain fundamental changes, dispose of assets, prepay certain indebtedness, make restricted payments, make investments, and engage in transactions with affiliates. In addition the Prior Credit Agreement also contained a financial covenant that required the Company to maintain a minimum amount of liquidity and customary events of default.

In connection with the Prior Credit Agreement, the Company incurred lender and other third-party costs of approximately $4.9 million in 2019, which were recorded as a deferred asset and are amortized to interest expense using a straight-line method over the term of the Prior Credit Agreement. As of December 25, 2021, the Prior Credit Agreement included a $50 million letter of credit facility and $11.5 million had been issued and outstanding.

In June 2022, the Company terminated the Prior Credit Agreement and repaid the entire outstanding principal balance of $40.0 million, in addition to accrued interest and other fees of $0.5 million. The Company also recorded $2.0 million in interest expense to write off the unamortized deferred debt issuance costs related to the Prior Credit Agreement.

Mortgage Payable

In March 2019, the Company mortgaged a property it owns. The Company received proceeds of $8.7 million in connection with the loan. The loan carries a fixed interest rate of 5.25% and is repayable in 59 equal monthly installments of principal and interest with the remaining unpaid principal balance plus accrued unpaid interest due five years from the date of the loan.

On September 24, 2021, the loan was amended to reduce the interest rate from 5.25% to 3.80% for the remaining 31 equal monthly installments of approximately $0.1 million, with the remaining principal payment at maturity date.

Legal Matters

NextGen Innovations, LLC

On August 9, 2022, NextGen Innovations, LLC ("NextGen") filed a complaint against us in the United States District Court for the Eastern District of Texas. The complaint asserts that through certain products we infringe on U.S. Patent Nos. 9,887,795, 10,263,723, and 10,771,181. The complaint alleges that NextGen is entitled to unspecified damages, costs, fees, expenses, interest, and injunctive relief. We are currently unable to predict the outcome of this litigation and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.

In addition to the matter described above, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material effect on our consolidated financial position, results of operations or cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Loss Contingencies

The Company is subject to the possibility of various losses arising in the ordinary course of business. These may relate to disputes, litigation and other legal actions. In the preparation of its quarterly and annual financial statements, the Company considers the likelihood of loss or the incurrence of a liability, including whether it is probable, reasonably possible or remote that a liability has been incurred, as well as the Company’s ability to reasonably estimate the amount of loss, in determining loss contingencies. In accordance with U.S. GAAP, an estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information to determine whether any accruals should be adjusted and whether new accruals are required. As of each of December 31, 2022 and December 25, 2021, the Company has accrued the estimated liabilities associated with certain loss contingencies.

Indemnification Obligations

From time to time, the Company enters into certain types of contracts that contingently require it to indemnify parties against third-party claims. The terms of such indemnification obligations vary. These contracts may relate to: (i) certain real estate leases under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; and (ii) certain agreements with the Company’s officers, directors and certain key employees, under which the Company may be required to indemnify such persons for liabilities.

In addition, the Company has agreed to indemnify certain customers for claims made against the Company’s products, where such claims allege infringement of third-party intellectual property rights, including, but not limited to, patents, registered trademarks, and/or copyrights. Under the aforementioned intellectual property indemnification clauses, the Company may be obligated to defend the customer and pay for the damages awarded against the customer under an infringement claim as well as the customer’s attorneys’ fees and costs. These indemnification obligations generally do not expire after termination or expiration of the agreement containing the indemnification obligation. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification. The Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements. The maximum potential amount of any future payments that the Company could be required to make under these indemnification obligations could be significant.

As permitted under Delaware law and the Company’s charter and bylaws, the Company has agreements whereby it indemnifies certain of its officers and each of its directors. The term of the indemnification period is for the officer’s or director’s lifetime for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements could be significant; however, the Company has a director and officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal.

Product Warranties

Activity related to product warranty was as follows (in thousands):


	December 31, 2022		December 25, 2021
Beginning balance	$	44,310	$	40,708
Charges to operations	27,176		23,061

Change in estimate(1)	(12,445)		6,286
Balance at the end of the period	$	36,621	$	44,310

(1)The Company records product warranty liabilities based on the latest quality and cost information available as of the date the revenue is recorded. The changes in estimate shown here are due to changes in overall actual failure rates, the mix of new versus used units related to replacement of failed units, and changes in the estimated cost of repair and product recalls. As the Company's products mature over time, failure rates and repair costs associated with such products generally decline leading to favorable changes in warranty reserves.

Letters of Credit and Bank Guarantees

The Company had $24.7 million and $22.5 million of standby letters of credit, bank guarantees and surety bonds outstanding as of December 31, 2022 and December 25, 2021, respectively. Details are sets in below table (in thousands).

Credit cards	—		150
Other liabilities	—		68
Total	$	24,735	$	22,500

Of the $20.9 million related to customer performance guarantees, approximately $4.0 million was used to secure surety bonds in the aggregate of $7.5 million as of December 31, 2022. Of the $16.3 million to customer performance guarantees, approximately $4.0 million was used to secure surety bonds in the aggregate of $5.5 million as of December 25, 2021.

Restricted Stock Units

Pursuant to the 2016 Plan, the Company has granted RSUs to employees and non-employee members of the Company's board of directors. All RSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date. The Company accounted for the fair value of the RSUs using the closing market price of the Company’s common stock on the date of grant. Amortization of stock-based compensation expense related to RSUs in 2022, 2021 and 2020 was approximately $54.1 million, $42.3 million and $36.1 million, respectively.

Performance Stock Units

Pursuant to the 2016 Plan, the Company has granted PSUs to certain of the Company’s executive officers, senior management and certain employees. All PSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date and if the performance metrics are not met within the time limits specified in the award agreements, the PSUs will be canceled.

PSUs granted to the Company's executive officers and senior management under the 2016 Plan during 2020, 2021 and 2022 are based on performance criteria related to a specific financial target over the span of a three-year performance period. These PSUs may become eligible for vesting to begin before the end of the three-year performance period, if the applicable financial target is met. The number of shares to be issued upon vesting of these PSUs are capped at the target number of PSUs granted. Certain other employees were awarded PSUs that will only vest upon the achievement of specific financial and operational performance criteria.

Loss before provision for income taxes from international operations was $20.2 million, $20.7 million and $37.3 million for the years ended December 31, 2022, December 25, 2021 and December 26, 2020, respectively.

The provisions for income taxes differ from the amount computed by applying the statutory federal income tax rates as follows:


	Years Ended
	December 31, 2022		December 25, 2021		December 26, 2020
Expected tax at federal statutory rate	21.0	%	21.0	%	21.0	%

Other	(6.0)	%	(2.3)	%	(0.4)	%
Effective tax rate	(37.1)	%	(7.5)	%	(3.0)	%

For 2022, the Company's income tax expense was $20.5 million with effective tax rate of (37.1)%. The difference between the effective income tax rate and the U.S federal statutory rate of 21% to income before income taxes is primarily the result of R&D credits, stock-based compensation, foreign income taxed at different rates and valuation allowances. The Company recognized an income tax expense of $12.0 million and $6.0 million in 2021 and 2020, respectively. The resulting effective tax rates were (7.5)% and (3.0)% for 2021 and 2020, respectively. The 2021 and 2020 effective tax rates differ from the expected statutory rate of 21%, based on the Company's ability to benefit from its U.S. loss carryforwards, offset by state income taxes, non-deductible stock-based compensation expenses and foreign taxes provided on foreign subsidiary earnings.

During 2022, the Company implemented a realignment of its internal supply chain and customer facing entities. The new structure aligned and consolidated the Company's intellectual property and the associated commercial risk and reward among the customer-facing entities in their internal supply chain and improved operational efficiency. The impact of this internal realignment is reflected in the Company’s tax provision for the year ended December 31, 2022.

Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis using enacted tax rates in effect for the year in which the differences are expected to reverse. Significant deferred tax assets and liabilities consist of the following (in thousands):

Total deferred tax liabilities	$	(26,687)	$	(72,178)
Net deferred tax assets (liabilities)	$	2,035	$	(400)

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company must consider all positive and negative evidence, including the Company's forecasts of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors in evaluating the need for a full or partial valuation allowance against its net U.S. deferred tax assets. Based on the available objective evidence, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the Company has provided a full valuation allowance against its domestic deferred tax assets, net of deferred tax liabilities, as of December 31, 2022 and December 25, 2021.

The Company intends to continue maintaining a full valuation allowance on its deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. However, considering the Company's current assessment of the probability of maintaining profitability, there is a reasonable possibility that, within the next year or two, sufficient positive evidence may become available to reach a conclusion that a portion of the valuation allowance will no longer be needed. As such, the Company may release a portion of its valuation allowance against its deferred tax assets within the next 12-24 months. This release, if

any, would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period such release is recorded.

Beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminated the right to deduct research and development expenditures for tax purposes in the period the expenses were incurred and instead requires all U.S. and foreign research and development expenditures to be amortized over five and fifteen tax years, respectively. Due to this required capitalization of research and development expenditures, the Company has recorded U.S. current income tax expense of $1.3 million for the year ended December 31, 2022. The U.S. current income tax provision is primarily for state taxes we anticipate paying as a result of statutory limitations on our ability to offset expected taxable income with net operating loss and research and development credit carry forwards. The increase in Federal taxable income due to R&D expense capitalization is offset by net operating carryover balance. It is expected that R&D expense capitalization will continue to generate Federal and State taxable income in future years and continue to utilize net operating loss and other available tax credits.

As of December 31, 2022, the Company had net operating loss carryforwards of approximately $507.0 million for federal income tax purposes which will begin to expire in 2032 if unused. The Company had net operating loss carryforwards of approximately $512.0 million for state income tax purposes which will begin to expire in the year 2023 if unused. The Company also had foreign net operating loss carryforwards of approximately $605.5 million, some of which will begin expiring in the year 2023 if unused.

As of December 31, 2022, the Company also had R&D credit carryforwards of approximately $49.3 million for federal income tax and $55.1 million for state income tax purposes. The federal R&D tax credit will begin to expire in 2023 if unused. State R&D tax credits will carry forward indefinitely.

As of December 31, 2022, the Company also had Foreign Tax credit carryforwards of approximately $38.9 million for federal income tax. The foreign tax credit will begin to expire in 2023 if unused.

Infinera Canada Inc., an indirect wholly owned subsidiary, has Scientific Research and Experimental Development Expenditures (“SRED”) credits available of $4.0 million to offset future Canadian income taxes payable as of December 31, 2022. Infinera Portugal subsidiary has a SIFIDE Credit of $4.3 million to offset future income tax payable in Portugal as of December 31, 2022. Canadian SRED credits will begin to expire in the year 2032 if not fully utilized. The Portugal SIFIDE credits will begin to expire in the year 2023.

At December 31, 2022, the Company had federal capital loss carryforwards of $19.6 million. If not utilized, the federal capital loss will expire in 2023.

The federal and state net operating loss carryforwards may be subject to significant limitations under Section 382 and Section 383 of the Internal Revenue Code of 1986, as amended (the "Code") and similar provisions under state law. The Tax Reform Act of 1986 contains provisions that limit the federal net operating loss carryforwards that may be used in any given year in the event of special occurrences, including significant ownership changes. The Company has completed a Section 382 review and has determined that none of its operating losses will expire solely due to Section 382 limitation(s).

The aggregate changes in the balance of gross unrecognized tax benefits were as follows (in thousands):

Ending balance	$	57,849	$	54,250	$	57,931

As of December 31, 2022, the cumulative unrecognized tax benefit was $57.8 million, of which $49.5 million was netted against deferred tax assets, which would have otherwise been subjected with a full valuation allowance. Of the total unrecognized tax benefit as of December 31, 2022, approximately $8.3 million, if recognized, would impact the Company’s effective tax rate. The amount of unrecognized tax benefit could be reduced upon expiration of the applicable statute of limitation. The potential reduction in unrecognized tax benefits during the next 12 months is not expected to be material.

As of December 31, 2022, December 25, 2021 and December 26, 2020, the Company had $1.3 million, $2.1 million and $2.9 million, respectively, of accrued interest or penalties related to unrecognized tax benefits, of which $0.8 million was included in the Company’s provision for income taxes in each of the years ended December 31, 2022, December 25, 2021 and December 26, 2020, respectively. The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the Company’s provision for income taxes.

The Company is potentially subject to examination by the Internal Revenue Service and the relevant state income taxing authorities under the statute of limitations for years 2003 and forward.

Included in the balance of income tax liabilities, accrued interest and penalties at December 31, 2022 is an immaterial amount related to tax positions for which it is reasonably possible that the statute of limitations will expire in various jurisdictions within the next twelve months.

Post U.S. Tax Reform, the Company and its subsidiaries do not have significant unremitted foreign earnings and the associated withholding and other taxes are not material for the fiscal year ended December 31, 2022.

17. Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the Company’s Chief Executive Officer (“CEO”). The Company’s CEO reviews financial information presented on a consolidated basis, accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. The Company has one business activity as a provider of optical transport networking equipment, software and services. Accordingly, the Company is considered to be in a single reporting segment and operating unit structure.

Revenue by geographic region is based on the shipping address of the customer. For more information regarding revenue disaggregated by geography, see Note 4, “Revenue Recognition” to the Notes to Consolidated Financial Statements.

Additionally, the following table sets forth our property, plant and equipment, net by geographic region (in thousands):

Defined Contribution Plans

The Company has established a savings plan under Section 401(k) of the Code (the “401(k) Plan”). As allowed under Section 401(k) of the Code, the 401(k) Plan provides tax-deferred salary contributions for eligible U.S. employees. Employee contributions are limited to a maximum annual amount as set periodically by the Code. The Company made voluntary cash contributions and matched a portion of employee contributions of $3.0 million, $2.8 million and $2.4 million for 2022, 2021, and 2020, respectively. Expenses related to the 401(k) Plan were insignificant for each of the years 2022, 2021, and 2020.

The Company has an ITP pension plan covering its Swedish employees. Commitments for old-age and survivors' pension for salaried employees in Sweden are vested through an insurance policy. Expenses related to the ITP pension plan were $2.5 million for 2022, $2.8 million for 2021 and $2.7 million for 2020.

The Company also provides defined contribution plans in certain foreign countries where required by local statute or at the Company's discretion. For the years ended December 31, 2022, December 25, 2021 and December 26, 2020, the Company had $4.9 million, $6.2 million, and $3.5 million related to post-retirement costs, respectively.

Pension Plans

Pension and Post-Retirement Benefit Plans

The Company has a number of post-employment plans in Germany, as well as a number of smaller post-employment plans in other countries, including both defined contribution and defined benefit plans. The defined benefit plans expose the Company to actuarial risks such as, investment risk, interest rate risk, life expectancy risk and salary risk. The characteristics of the defined benefit plans and the risks associated with them vary depending on legal, fiscal, and economic requirements.

Components of Net Periodic Benefit Cost

Net periodic benefit cost for the Company's pension and other post-retirement benefit plans consisted of the following (in thousands):

Amortization of net actuarial loss	326		3,383		1,884
Total net periodic (benefit) cost	$	(1,061)	$	2,104	$	1,909

Actuarial gains and losses are amortized using a corridor approach. The gain/loss corridor is equal to 10% of the greater of the pension benefit obligation and the market-related value of assets. Gains and losses in excess of the corridor are generally amortized over the average future working lifetime of the pension plan participants. The service cost component is included in operating expenses in the Company's consolidated statements of operations. All other components are included in Other income (expense), net in the Company's consolidated statements of operations.

The following table sets forth the changes in accumulated other comprehensive income (loss) for the Company's benefit plans (pre-tax) (in thousands):


	December 31, 2022		December 25, 2021
Beginning balance	$	4,297	$	(11,666)
Net actuarial gain arising in current year	22,538		12,580
Amortization of net actuarial loss(1)	326		3,383

Ending balance	$	27,161	$	4,297

(1) The actuarial gain for the fiscal years ended December 31, 2022 and December 25, 2021 is primarily due to the change in the discount rate. Amounts recorded in accumulated other comprehensive income (loss) expected to be amortized as a part of net periodic pension cost during 2023 is $3.7 million (pre-tax).

Assumptions

Certain actuarial assumptions used in computing the benefit obligations for the major plans are as follows:


	December 31, 2022		December 25, 2021
Discount rate	4.17	%	1.20	%
Salary growth rate	2.50	%	2.25	%

Investment Policy

The financial position of the Company’s funded status is the difference between the fair value of plan assets and projected benefit obligations. Volatility in funded status occurs when asset values change differently from liability values and can result in fluctuations in costs in financial reporting. The Company’s investment policies and strategies are designed to increase the rate of assets to plan liabilities at an appropriate level of funded status volatility. Asset allocation decisions are recommended by the trustees for the specific plan and agreed to by the Company's management. Investment objectives are designed to generate returns that will enable the plan to meet its future obligations. The Company's management reviews the investment strategy and performance semi-annually and discuss alternatives to manage volatility.

Basis for Expected Long-Term Rate of Return on Plan Assets

The expected long-term rate of return on plan assets reflects the expected returns for each major asset class in which the plan invests and the weight of each asset class in the target mix. Expected asset returns reflect the current yield on government bonds, risk premiums for each asset class and expected real returns which considers each country’s specific inflation outlook. The expected return is set using a low to medium risk profile and to meet the market expectations over a longer period of time to meet the obligations in the future.

Fair Value of Plan Assets

The following tables present the fair value of plan assets for pension and other benefit plans by major asset category (in thousands):

Valuation Techniques

The following describes the valuation techniques used to measure the fair value of the assets shown in the table above. Equity funds are invested in traded securities and are recorded at market value as of the balance sheet date. Insurance contracts are recorded at cash surrender value of the policies. Mixed fund and pension fund are valued at the amounts as provided by the insurance companies who manage the funds and represent fair market value at the date of the balance sheet.

Transfers Between Levels

Any transfers between levels in the fair value hierarchy are recognized as of the end of the reporting period. No material transfers between levels occurred during the fiscal year ended December 31, 2022.

Future Contributions

In 2023, the Company does not expect to make additional contributions to the plan.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Attached as exhibits to this Form 10-K are certifications of our CEO and CFO, which are required in accordance with Rule 13a-14 of the Exchange Act. This “Controls and Procedures” section includes information concerning the internal controls and controls evaluation referred to in the certifications.

Evaluation of Disclosure Controls and Procedures

An evaluation was performed by our management, with the participation of our CEO and our CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d -15(e) under the Exchange Act). Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our CEO and CFO concluded that, as of December 31, 2022, our disclosure controls and procedures were effective.

Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, does not expect that our disclosure controls or our internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to its costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in business conditions or deterioration in the degree of compliance with policies or procedures.

Changes in Internal Control over Financial Reporting

During the three months ended December 31, 2022 there were no changes in our internal control over financial reporting which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We are continually monitoring and assessing the

117

COVID-19 pandemic situation to minimize the impact, if any, on the design and operating effectiveness on our internal controls.

Management’s Report on Internal Control Over Financial Reporting

Our management, with the participation of our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022, the end of our fiscal year. Management based its assessment on the framework established in the 2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“2013 COSO framework”). Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment. This assessment is supported by testing and monitoring performed by our internal audit and finance personnel utilizing the 2013 COSO framework.

Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of 2022 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. GAAP.

The effectiveness of our internal control over financial reporting as of the end of 2022 has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in their report, which is included elsewhere herein.

The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan (including Section 5(c) of the Plan). If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Administrator. If Participant is a U.S. taxpayer, the payment of Shares vesting pursuant to this Section 4 in all cases will be paid at a time and in a manner that is exempt from, or complies with, Section 409A. The immediately preceding sentence may be superseded in a future agreement or amendment to this Agreement only by direct and specific reference to such sentence.

(b) Acceleration Relating to Death or Disability. Without limiting the terms of Section 4(a), if Participant ceases to be a Service Provider by reason of Disability or Participant’s death (except resulting from suicide), then the Restricted Stock Units that remain unvested as of the date Participant’s status as a Service Provider terminated shall fully vest.

5.Forfeiture upon Termination of Status as a Service Provider. Notwithstanding any contrary provision of this Agreement, the balance of the Restricted Stock Units that have not vested as of the time of Participant’s termination as a Service Provider for any or no reason and Participant’s right to acquire any Shares hereunder will immediately terminate; the Administrator shall have the exclusive discretion to determine when Participant ceases to be a Service Provider for purposes of the Restricted Stock Unit grant.

6.Payment after Vesting.

(a) Subject to Section 8, any Restricted Stock Units that vest will be paid to Participant (or, in the event of Participant’s death, to his or her estate) in whole Shares, subject to satisfying any Tax Obligations (as defined below). Subject to the provisions of Section 6(b), such vested Restricted Stock Units shall be paid in Shares as soon as practicable after vesting, but in each such case within sixty (60) days following the vesting date. In no

Form of Global RSU Agreement (Ex. A)

event will Participant be permitted, directly or indirectly, to specify the taxable year of the payment of any Shares underlying the Restricted Stock Units payable under this Agreement.

(b) The following provisions apply if Participant is a U.S. taxpayer:

Notwithstanding anything in the Plan or this Agreement or any other agreement (whether entered into before, on or after the Date of Grant) to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units occurs in connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to Participant’s death, and if (x) Participant is a U.S. taxpayer and a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the payment of such accelerated Restricted Stock Units will result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless Participant dies following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid out as described in Section 7 as soon as practicable following his or her death.

It is the intent of this Agreement that it and all payments and benefits to U.S. taxpayers hereunder be exempt from, or comply with, the requirements of Section 409A so that none of the Restricted Stock Units provided under this Agreement or Shares issuable thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities and ambiguous terms herein will be interpreted to be so exempt or so comply. Each payment payable under this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). However, in no event will the Company have any responsibility, liability or obligation to reimburse, indemnify or hold harmless Participant, for any taxes imposed or other costs incurred as a result of Section 409A.

7.Death of Participant. Any distribution or delivery to be made to Participant under this Agreement will, if Participant is then deceased, be made to the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

8.Tax Withholding. Participant acknowledges and agrees that no Shares will be issued to Participant unless and until satisfactory arrangements (as determined by the Administrator) will have been made by Participant with respect to the payment of Tax Obligations (as defined below) which the Company or its Parent or Subsidiary employing or retaining Participant (the “Employer”) determines must be withheld with respect to these Restricted Stock Units or any Shares issuable upon vesting. For purposes of this Agreement, “Tax Obligations” means tax, social insurance and social security liability obligations and requirements in connection with this Award, including, without limitation, (i) all federal, state, and local income, employment and any other taxes (including Participant’s U.S. Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company (or Employer, as applicable), (ii) Participant’s and, to the extent required by the Company (or Employer, as applicable), the Company’s (or Employer’s) fringe benefit tax liability, if any, associated with the grant, vesting, or settlement of this Award, or sale of Shares issued under this Award, and (iii) any other taxes or social insurance or social security liabilities or premium the responsibility for which Participant has, or has agreed to bear, with respect to this Award (or issuance of Shares or other consideration thereunder). Participant acknowledges and agrees that the ultimate liability for all Tax Obligations related to Participant’s participation in the Plan is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer, if any. Participant further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends and/or any dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of the Award or any aspect of the Restricted Stock Units to reduce or eliminate Participant’s liability for Tax Obligations or achieve any particular tax result. Further, if Participant is subject to Tax Obligations in more than one jurisdiction, Participant acknowledges and agrees that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any Tax Obligations at the time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to the terms of this Agreement or the Plan or at the time any Tax Obligations related to Restricted Stock Units otherwise are due, Participant will permanently forfeit such Restricted Stock Units and any right to receive Shares hereunder, and the Restricted Stock Units will be returned to the Company at no cost to the Company.

Form of Global RSU Agreement (Ex. A) - 2 -

Prior to any relevant taxable or tax withholding event, as applicable, Participant agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax Obligations. In this regard, Participant authorizes the Company and/or the Employer, or their respective agents, to satisfy the obligations with regard to all Tax Obligations by one or a combination of the following methods: (1) withholding from the proceeds of the sale of Shares acquired at settlement of the Restricted Stock Units, either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent); (2) withholding from Participant’s salary, wages or other cash compensation payable to Participant by the Company and/or the Employer; or (3) withholding in Shares acquired at vesting of the Restricted Stock Units. For Section 16 Officers (i.e., persons designated by the Company as being required to file Section 16 reports pursuant to Section 16 of the Exchange Act), the Company and/or the Employer, or their respective agents, will satisfy the obligations by method (3) above, unless otherwise determined by the Administrator, in its sole discretion. For employees who are not Section 16 Officers, the Company and/or the Employer, or their respective agents, will generally satisfy the obligations by method (1) above unless otherwise determined by the Administrator. Employees who are not Section 16 Officers and who are resident in the United States may choose to satisfy their withholding obligations by method (2) above.

Alternatively, or in addition to the withholding methods above, if permissible under Applicable Laws, the Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit or require Participant to satisfy the Tax Obligations with respect to the Restricted Stock Units, in whole or in part (without limitation), by delivery of cash or check to the Company or the Employer.

The Company may withhold or account for Tax Obligations by considering statutory withholding rates or other applicable withholding rates, including up to maximum applicable rate in Participant’s jurisdiction. In the event the application of the withholding rate determined by the Company leads to over-withholding, Participant may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent value in Shares) or, if not refunded, Participant may be able to seek a refund from the applicable tax authority. In the event of under-withholding by the Company or the Employer for any reason, Participant may be required to pay any additional Tax-Obligations directly to the applicable tax authority. If the obligation for Tax Obligations is satisfied by withholding in Shares, for tax purposes, Participant is deemed to have been issued the full number of Shares subject to the vested Restricted Stock Units, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax Obligations.

9. Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.

10.Nature of Grant. In accepting the Award, Participant acknowledges, understands and agrees that:

(a) the Plan is established voluntarily by the Company, it is discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted in the Plan;

(b) the Award of Restricted Stock Units is voluntary and occasional and does not create any contractual or other right to receive future awards of Restricted Stock Units, or benefits in lieu of Restricted Stock Units even if Restricted Stock Units have been awarded in the past;

(d) Participant is voluntarily participating in the Plan;

(e) the Restricted Stock Units and the Shares underlying the Restricted Stock Units, and the income from and value of same, are not intended to replace any pension rights or compensation;

(f) the Restricted Stock Units and the Shares underlying the Restricted Stock Units, and the income from and value of same, are not part of normal or expected compensation or salary for purposes including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal or end-of-service payments, bonuses, long-term service awards, pension or retirement or welfare benefits or similar payments;

Form of Global RSU Agreement (Ex. A) - 3 -

(g) the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(h) no claim or entitlement to compensation or damages shall arise from the forfeiture of the Restricted Stock Units or the Shares acquired at vesting if Participant ceases to be a Service Provider (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any);

(i) for purposes of the Award of Restricted Stock Units, Participant’s status as a Service Provider will be considered terminated when Participant is no longer actively providing services to the Company or a Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where Participant is employed or retained or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Agreement or determined by the Company, Participant’s right to vest in the Restricted Stock Units under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or retained or the terms of Participant’s employment or service agreement, if any); the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Award of Restricted Stock Units (including whether Participant may still be considered to be providing services while on a leave of absence pursuant to Section 13 of the Plan and consistent with Applicable Laws);

(j) unless otherwise provided in the Plan or by the Company in its discretion, the Restricted Stock Units and the Shares underlying the Restricted Stock Units, and the income from and value of same, do not create any entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares;

(k) unless otherwise agreed with the Company, the Restricted Stock Units and the Shares underlying the Restricted Stock Units, and the income from and value of same, are not granted as consideration for, or in connection with, any services Participant may provide as a director of any Subsidiary; and

(l) if Participant is providing services outside the United States:

(A) the Restricted Stock Units and the Shares underlying the Restricted Stock Units, and the income from and value of same, are not part of normal or expected compensation or salary for any purpose; and

(B) neither the Company, the Employer nor any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement.

11.No Advice Regarding Grant. The Company is not providing any tax, legal, or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan or his or her acquisition or sale of the underlying Shares. Participant should therefore consult with his or her own personal tax, legal and financial advisors regarding the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by the Agreement and all other aspects of Participant’s participation in the Plan before taking any action related to the Plan.

12.Data Privacy Information and Consent. In order to participate in the Plan, Participant will need to review the information provided in this Section 12 regarding the collection, processing and transfer of Personal Data (as defined below) and declare his or her consent to the processing and transfer of Personal Data as described below.

(a) Data Collection and Usage. The Company and the Employer collect, process and use certain personal information about Participant, including, but not limited to, Participant’s name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any Shares or directorships held in the Company or any Parent or

Form of Global RSU Agreement (Ex. A) - 4 -

Subsidiary, details of all Awards granted under the Plan or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Personal Data”), for the purposes of implementing, administering and managing the Plan. The legal basis, where required, for the processing of Personal Data is Participant’s consent.

(b) Stock Plan Administration Service Provider. The Company transfers Personal Data to E*TRADE Financial Services, Inc. and its affiliated companies, an independent service provider based in the United States, which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Personal Data with such other provider serving in a similar manner. Participant may be asked to agree on separate terms and data processing practices with the service provider, with such agreement being a condition to the ability to participate in the Plan.

(c) International Data Transfer. The Company and some of its service providers are based in the United States. Participant’s country or jurisdiction may have different data privacy laws and protections than the United States. The Company’s legal basis for the transfer of Personal Data, where required, is Participant’s consent.

(d) Data Retention. The Company will hold and use Personal Data only as long as is necessary to implement, administer and manage Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax and security laws. When the Company no longer needs Personal Data, the Company will remove it from its systems. If the Company keeps Personal Data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be Participant’s consent.

(d) Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and Participant is providing the consents herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke the consent, Participant’s salary from or employment with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant Participant Restricted Stock Units under the Plan or other Awards or administer or maintain such Awards.

(e) Data Subject Rights. Participant may have a number of rights under data privacy laws in his or her jurisdiction. Subject to the conditions set out in Applicable Laws and depending on where Participant is based, such rights may include the right to (i) request access to or copies of Personal Data, (ii) rectify incorrect Personal Data, (iii) delete Personal Data, (iv) restrict the processing of Personal Data, (v) restrict the portability of Personal Data, (vi) lodge complaints with competent authorities, and/or (vii) receive a list with the names and addresses of any potential recipients of Personal Data. To receive clarification regarding these rights or to exercise these rights, Participant can contact his or her local human resources representative.

13.No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS AN ACTIVE SERVICE PROVIDER, WHICH UNLESS OTHERWISE REQUIRED BY APPLICABLE LAW IS AT THE WILL OF THE COMPANY OR THE EMPLOYER (OR ANY PARENT OR SUBSIDIARY) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS AWARD OF RESTRICTED STOCK UNITS OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, ANY OTHER PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY OR THE EMPLOYER TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW, MAY BE AT ANY TIME, WITH OR WITHOUT CAUSE.

14.Language. Participant acknowledges that Participant is proficient in the English language and understands the content of this Agreement and other Plan-related materials. If Participant has received this Agreement or any other document related to this Agreement and/or the Plan translated into a language other than

Form of Global RSU Agreement (Ex. A) - 5 -

16.Grant is Not Transferable. Except to the limited extent provided in Section 7, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process.

17.Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

18.Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any U.S. federal, state, local or non-U.S. law, the tax code and related regulations or the rulings or regulations of the U.S. Securities and Exchange Commission (the “SEC”) or any other governmental regulatory body or the clearance, consent or approval of the SEC or any other governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such listing, registration, qualification, rule compliance, clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Where the Company determines that the delivery of the payment of any Shares will violate U.S. federal, state, local or non-U.S. securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements of any such U.S. federal, state, local or non-U.S. law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange.

19.Appendix. The Award of Restricted Stock Units shall be subject to any additional provisions set forth in the Appendix for Participant’s country, if any.

Form of Global RSU Agreement (Ex. A) - 6 -

any Restricted Stock Units have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons.

Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party designated by the Company.

23.Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

24.Agreement Severable. In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement.

25.Modifications to the Agreement. This Agreement constitutes the entire understanding of the parties on the subjects covered. Participant expressly warrants that he or she is not accepting this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Agreement, the Company reserves the right to revise this Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A in connection to this Award of Restricted Stock Units.

26.Amendment, Suspension or Termination of the Plan. By accepting this Award, Participant expressly warrants that he or she has received an Award of Restricted Stock Units under the Plan, and has received, read and understood a description of the Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the Company at any time.

27.Governing Law and Venue. This Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Award of Restricted Stock Units or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation shall be conducted in the courts of Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Award of Restricted Stock Units is made and/or to be performed.

28.Imposition of Other Requirements. The Company reserves the right to impose other requirements on Participant’s participation in the Plan, on the Restricted Stock Units and on any Shares underlying the Restricted Stock Units, to the extent the Company determines it is necessary or advisable for legal and administrative reasons and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

Form of Global RSU Agreement (Ex. A) - 7 -

29.Waiver. Participant acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by Participant or any other participant.

30.Successors and Assigns. The Company may assign any of its rights under the Agreement to single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement will be binding upon Participant and his or her heirs, executors, administrators, successors and assigns. The rights and obligations of Participant under this Agreement may be assigned only with the prior written consent of the Company.

31.Insider-Trading/Market-Abuse Laws. Participant acknowledges that he or she may be subject to insider-trading and/or market-abuse laws in applicable jurisdictions, including but not limited to the United States and Participant’s country, which may affect his or her ability to purchase or sell Shares acquired under the Plan during such times as Participant is considered to have “inside information” regarding the Company (as defined by the laws in applicable jurisdictions). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders Participant places before possessing inside information. Furthermore, Participant could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Third parties include fellow employees. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider-trading policy. Participant is responsible for complying with any applicable restrictions, so Participant should speak to his or her personal legal advisor for further details regarding any applicable insider-trading and/or market-abuse laws in applicable jurisdictions.

32.Foreign Asset/Account Reporting and Exchange Control Requirements. Participant acknowledges that there may be certain foreign asset and/or account reporting and/or exchange control requirements which may affect his or her ability to acquire or hold the Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends paid on the Shares acquired under the Plan) in a brokerage or bank account outside his or her country. Participant may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country. Participant also may be required to repatriate sale proceeds or other funds received as a result of participating in the Plan to his or her country through a designated bank or broker within a certain time after receipt.

Accordingly, Participant should seek appropriate professional advice as to how the relevant laws in Participant’s country may apply to his or her situation.

Finally, if Participant is a citizen or resident of a country other than the one in which he or she is currently residing and/or working, transfers employment and/or residency after the Restricted Stock Units are granted, or is considered a resident of another country for local law purposes, the information contained herein may not be applicable to Participant.

Securities Law Information. Investment in Shares involves a degree of risk.

SÆRLIG MEDDELELSE TIL MEDARBEJDERE I DANMARK

ARBEJDSGIVERERKLÆRING

I henhold til § 3, stk. 1, i lov om brug af køberet eller tegningsret mv. i ansættelsesforhold (“Aktieoptionsloven”) er du berettiget til i en skriftlig erklæring at modtage følgende oplysninger om deltagelse i Infinera Corporation (“Infinera”) 2016 Equity Incentive Plan (“Planen”).

Denne erklæring indeholder generelt kun de oplysninger, der er nævnt i Aktieoptionsloven, medens de øvrige kriterier og betingelser for din tildeling af begrænsede aktier (“Restricted Stock Units” eller “RSUer”) er beskrevet nærmere i Planen, i Global Terms and Conditions of Restricted Stock Units, inkl. bilag (“Aftalen”) og i Notice of Restricted Stock Unit Grant (“Meddelelsen”), som er udleveret til dig. I tilfælde af uoverensstemmelser mellem en bestemmelse i denne Arbejdsgivererklæring og bestemmelserne i Planen, Aftalen eller Meddelelsen har denne Arbejdsgivererklæring forrang.

1. Tidspunkt for tildeling

Tidspunktet for tildelingen af dine RSUer er den dag, hvor Administratoren (Administrator) (som defineret i Planen) godkendte din tildeling og besluttede, at den skulle træde i kraft. Tidspunktet fremgår af Aftalen.

2. Kriterier og betingelser for RSU-tildelingen

Tildelingen af RSUer i henhold til Planen sker alene efter Administrators eget skøn. Medarbejdere (Employees) og Konsulenter (Consultants) (som defineret i Planen) i Infinera og dettes Moderselskaber (Parents) og Datterselskaber (Subsidiaries) (som defineret i Planen) kan deltage i Planen.

3. Modningstidspunkt for RSUerne

Dine betingede aktieoptioner modnes over en periode, forudsat at du fortsat er ansat i eller arbejder for Selskabet eller en tilknyttet virksomhed, medmindre optionen er modnet eller bortfaldet på et tidligere tidspunkt af de i Ordningen anførte årsager.

4. Udnyttelseskurs

Der er ikke knyttet nogen udnyttelseskurs til RSUerne. Hver RSU giver dig i forbindelse med deres modning ret til at modtage én ordinær aktie i Selskabet, uden at det koster dig noget (bortset fra gældende skatter og afgifter).

5. Din retsstilling i forbindelse med ophør af din Ansættelsesstatus

Dine RSUer vil i tilfælde af ophør af din Ansættelsesstatus blive behandlet i overensstemmelse med ophørsbestemmelserne i Aftalen, som er kort beskrevet umiddelbart nedenfor.

I tilfælde af ophør af din Ansættelsesstatus, og medmindre andet fremgår nedenfor, vil alle dine RSUer, der ikke har opfyldt modningsbetingelsen, blive annulleret eller bortfalde. Hvis ophøret af din Ansættelsesstatus skyldes dødsfald eller Invaliditet (Disability) (som defineret i Planen), vil dine RSUer blive modnet fuldt ud med omgående virkning.

6. Økonomiske aspekter ved at deltage i Planen

Tildelingen af RSUer har ingen umiddelbare økonomiske konsekvenser for dig. Værdien af RSUerne indgår ikke i beregningen af feriepenge, pensionsbidrag eller andre lovpligtige, vederlagsafhængige ydelser.

Aktier er finansielle instrumenter, og investering i aktier vil altid være forbundet med en økonomisk risiko. Den fremtidige værdi af Infinera aktier kendes ikke og kan ikke forudsiges med sikkerhed.

The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company, the Employer or any Parent or Subsidiary on an ongoing basis.

Accounting Policies [Abstract]

Significant Accounting Policies Significant Accounting Policies
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. Estimates, assumptions and judgements made by management include inventory valuation, revenue recognition, accounting for income taxes, stock-based compensation, employee benefit and pension plans, manufacturing partner and supplier liabilities, allowances for sales returns, allowances for credit losses, useful life of intangibles and property, plant and equipment, impairment loss related to lease abandonment, accrued warranty, operating and finance lease liabilities, restructuring and other related costs and loss contingencies. The Company bases its assumptions on historical experience and also on assumptions that it believes are reasonable. Actual results could differ materially from those estimates. These estimates may change as new events occur and additional information emerges, and such changes are recognized or disclosed in the Company's consolidated financial statements.
Revenue Recognition
The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.
The Company determines revenue recognition by applying the following five-step approach:
•identification of the contract, or contracts, with a customer;
•identification of the performance obligations in the contract;
•determination of the transaction price;
•allocation of the transaction price to the performance obligations in the contract; and
•recognition of revenue when, or as, the Company satisfies a performance obligation.
Many of the Company's product sales are sold in combination with installation and deployment services along with initial hardware and software support. The Company's product sales are also sold at times with spares management, on-site hardware replacement services, network operations management, software subscription services, extended hardware warranty and training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription services include software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.
Spares management and on-site hardware replacement services include the replacement of defective units at customer sites in accordance with specified service level agreements. Network operations management includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. The Company evaluates each promised good and service in a contract to determine whether it represents a distinct performance obligation or should be accounted for as a combined performance obligation.
Services revenue includes software subscription services, installation and deployment services, spares management, on-site hardware replacement services, network operations management, extended hardware warranty and training. Revenue from software subscription services, spares management, on-site hardware replacement services, network operations management and extended hardware warranty contracts is deferred and is recognized ratably over the contractual support period, which is generally one year, as services are provided over the course of the entire period. Revenue related to training and installation and deployment services is recognized upon completion of the services.
Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. The Company typically satisfies its performance obligations upon shipment or delivery of product depending on the contractual terms. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. The Company assesses its ability to collect from its customers based primarily on the creditworthiness and past payment history of the customer.
For sales to resellers, the same revenue recognition criteria apply. It is the Company’s practice to identify an end-user prior to shipment to a reseller. The Company does not offer rights of return or price protection to its resellers.
The Company reports revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
Customer Purchase Commitments
The Company sells software licenses that provide customers the ability to purchase incremental bandwidth capacity on an already-deployed piece of hardware. Infinera Instant Bandwidth-enabled systems generally include a specific initial capacity and incremental capacity can be added by the purchase of Instant Bandwidth licenses. Instant Bandwidth licenses are considered distinct performance obligations because customers can provision additional transmission capacity on demand without the deployment of any incremental equipment.
Some contracts commit the customer to purchase incremental Instant Bandwidth licenses within a specified time frame from the initial shipment of the Instant Bandwidth-enabled hardware. The time frame varies by customer and generally ranges between 12 to 24 months. If the customer does not purchase the additional capacity within the time frame as stated in the contract, the Company has the right to deliver and invoice such Instant Bandwidth licenses to the customer. Future committed licenses are considered to be additional performance obligations when a minimum purchase obligation is present, as evidenced by enforceable rights and obligations. As such, the Company is required to estimate the variable consideration for future Instant Bandwidth licenses as part of determining the contract transaction price.
Contract Termination Rights
The contract term is determined on the basis of the period over which the parties to the contract have present enforceable rights and obligations. Certain customer contracts include a termination for convenience clause that allows the customer to terminate services without penalty, upon advance notification. For such contracts, the service duration is limited to the non-cancelable portion of the contract.
Variable Consideration
The consideration associated with customer contracts is generally fixed. Variable consideration includes discounts, rebates, refunds, credits, incentives, penalties, or other similar items. The amount of consideration that can vary is not a substantial portion of total consideration.
Variable consideration estimates are re-assessed at each reporting period until a final outcome is determined. The changes to the original transaction price due to a change in estimated variable consideration will be applied on a retrospective basis, with the adjustment recorded in the period in which the change occurs.
Stand-alone Selling Price
Stand-alone selling price is the price at which an entity would sell a good or service on a stand-alone (or separate) basis at contract inception. Under this model, the observable price of a good or service sold separately provides the best evidence of stand-alone selling price. However, in certain situations, stand-alone selling prices will not be readily observable and the entity must estimate the stand-alone selling price.
When allocating on a relative stand-alone selling price basis, any discount provided in the contract is generally allocated proportionately to all of the performance obligations in the contract.
The majority of products and services offered by the Company have readily observable selling prices. For products and services that do not, the Company generally estimates stand-alone selling price using the market assessment approach based on expected selling price and adjust those prices as necessary to reflect the Company’s costs and margins. As part of its stand-alone selling price policy, the Company reviews product pricing on a periodic basis to identify any significant changes and revise its expected stand-alone selling price assumptions as appropriate.
Shipping and Handling
The Company treats shipping and handling activities as costs to fulfill the Company's promise to transfer products. Shipping and handling fees billed to customers are recorded as a reduction to cost of product.
Capitalization of Costs to Obtain a Contract
The Company has assessed the treatment of costs to obtain or fulfill a contract with a customer. Sales commissions have historically been expensed as incurred. Under Topic 606, the Company capitalizes sales commissions related to multi-year service contracts, which are paid for upfront, and amortizes the asset over the period of benefit, which is the service period. Sales commissions paid on service contract renewals, are commensurate with the sales commissions paid on the initial contracts.
Transaction Price Allocated to the Remaining Performance Obligation
The Company’s remaining performance obligations represent the transaction price allocated to performance obligations that are unsatisfied or partially satisfied as of period end, consisting of deferred revenue and backlog. The Company’s backlog represents purchase orders received from customers for future product shipments and services that are unsatisfied or partially satisfied as of period end. The Company’s backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, may be canceled without penalty. Orders in backlog may be fulfilled several quarters following receipt or may relate to multi-year support service obligations.
Stock-Based Compensation
Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period (generally the vesting period) under the straight-line amortization method. The Company accounts for forfeitures as they occur.
The Company estimates the fair value of the rights to acquire stock under its 2007 Employee Stock Purchase Plan (the “ESPP”) using the Black-Scholes option pricing formula. The ESPP provides for consecutive six-month offering periods and the Company's historical volatility data in the valuation of shares that are purchased under the ESPP.
The Company accounts for the fair value of restricted stock units (“RSUs”) using the closing market price of the Company’s common stock on the date of grant. For new-hire grants, RSUs typically vest ratably on an annual basis over four years. For annual refresh grants, RSUs typically vest ratably over 18 months to three years.
Performance Stock Units ("PSUs") granted to the Company's executive officers and senior management during 2019, 2020, 2021 and 2022 are based on performance criteria related to specific financial targets over the span of a two or three-year performance period. These PSUs may become eligible for vesting to begin before the end of the applicable performance period, if the applicable financial target is met. The number of shares to be issued upon vesting of these PSUs is capped at the target number of PSUs granted. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.
In addition, the Company granted other PSUs to certain employees that only vest upon the achievement of specific operational performance criteria. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.
Employee Benefit and Pension Plans
The Company operates a number of post-employment plans in Germany, as well as smaller post-employment plans in other countries, including both defined contribution and defined benefit plans. Benefit cost and obligations pertaining to these plans are based on assumptions for the discount rate, expected return on plan assets, mortality rates, expected salary increases, health care cost trend rates and attrition rates. The discount rate assumption is based on current investment yields of high-quality fixed-income securities with maturities similar to the expected benefits payment period. Mortality rates help predict the expected life of plan participants. The expected increase in the compensation levels assumption reflects the Company's actual experience and future expectations. The expected long-term return on plan assets is determined based on asset allocations, historical portfolio results, historical asset correlations and management’s expected returns for each asset class. The Company evaluates its expected return assumptions annually including reviewing current capital market assumptions to assess the reasonableness of the expected long-term return on plan assets. The Company updates the expected long-term return on assets when the Company observes a sufficient level of evidence that would suggest the long-term expected return has changed.
Research and Development
All costs to develop the Company’s hardware products are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s software products are released soon after technological feasibility has been established. As a result, costs subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.
Advertising
All advertising costs are expensed as incurred. Advertising expenses in 2022, 2021 and 2020 were $1.5 million, $1.6 million, and $1.3 million, respectively.
Accounting for Income Taxes
As part of the process of preparing its consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in consolidated statements of operations become deductible expenses under applicable income tax laws or loss, or credit carryforwards are utilized. Accordingly, realization of deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.
The Company must assess the likelihood that some portion or all of its deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent the Company believes that recovery does not meet the “more-likely-than-not” standard, it must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities and any valuation allowance
recorded against our net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including the Company's forecast of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors. Based on the available objective evidence, at December 31, 2022, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.
During 2022, the Company executed an internal realignment of its supply chain and customer-facing entities. Among other things, the new structure aligned and consolidated the exploitation of its intellectual property and the allocation of the associated commercial risk and reward with the customer-facing entities that manage its supply chain. The impact of this internal realignment is reflected in the Company’s tax provision for the year ended December 31, 2022.
Foreign Currency Translation and Transactions
The Company considers the functional currencies of its foreign subsidiaries to be the local currency. Assets and liabilities recorded in foreign currencies are translated at the exchange rate as of the balance sheet date, revenue, costs and expenses are translated at average exchange rates in effect during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets and consolidated statements of comprehensive income (loss).
For all non-functional currency account balances, the re-measurement of such balances to the functional currency will result in either a foreign exchange transaction gain or loss, which is recorded to other income (loss), net, in the Company's consolidated statement of operations, in the same period that the re-measurement occurred. Aggregate foreign exchange transactions recorded was gain of $12.8 million in 2022 and losses of $17.2 million and $0.2 million, in 2021 and 2020, respectively.
The Company enters into foreign currency exchange forward contracts to reduce the impact of foreign exchange fluctuations on earnings from certain non-functional currency account balances denominated primarily in euros and British pounds.
Cash and Cash Equivalents
Cash consists primarily of cash in bank deposit accounts which, at times, a portion may exceed federally insured limits. The Company has not experienced any losses in such accounts.
The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.
Fair Value Measurement
Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.
Valuation techniques used by the Company are based upon observable and unobservable inputs. Observable or market inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about market participant assumptions based on the best information available. Observable inputs are the preferred source of values. These two types of inputs create the following fair value hierarchy:
Level 1 – Quoted prices in active markets for identical assets or liabilities.
Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 – Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.
The Company measures its cash equivalents, foreign currency exchange forward contracts and debt securities at fair value and classifies them in accordance with the fair value hierarchy on a recurring basis.
Foreign Currency Exchange Forward Contracts
As discussed in Note 6, “Derivative Instruments" to the Notes to Consolidated Financial Statements, the Company historically held non-speculative foreign exchange forward contracts to hedge certain foreign currency exchange exposures. The Company estimates the fair values of derivatives based on quoted market prices or pricing models using current market rates. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies.
Facilities-related Charges
The Company estimates the fair value of its facilities-related charges associated with its restructuring plans, based on estimated future discounted cash flows and unobservable inputs, which includes the amount and timing of estimated sublease rental receipts that the Company can reasonably obtain over the remaining lease term and the discount rate.
Accounts Receivable and Allowances for Credit Losses
Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for estimated credit losses resulting from the inability of its customers to make required payments and reviewed the allowance quarterly. The Company determines expected credit losses by performing credit evaluations of its customers' financial condition, establishing both a general reserve and specific reserve for customers in adverse financial condition and adjusting for its expectations of changes in conditions that may impact the collectability of outstanding receivables. The Company considers a customer's receivable balance past due when the amount is due beyond the credit terms extended, The Company considers factors such as historical experience, credit quality, age of the accounts receivable balances, and geographic or country-specific risks. Amounts are written off when receivables are determined to be uncollectible.
Allowances for Sales Returns
Customer product returns are approved on a case by case basis. Specific reserve provisions are made based upon a specific review of all the approved product returns where the customer has yet to return the products to generate the related sales return credit at the end of a period. Estimated sales returns are provided for as a reduction to revenue. At December 31, 2022, December 25, 2021 and December 26, 2020, revenue was reduced for estimated sales returns by $3.6 million, $0.8 million, and $2.4 million, respectively.
Concentration of Risk
Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents and restricted cash, foreign exchange contracts and accounts receivable.
The risk with respect to foreign exchange contracts is mitigated by entering into these contracts with a large high-quality financial institution and the Company monitors the creditworthiness of the counterparty consistently.
The risk with respect to accounts receivable is mitigated by ongoing credit evaluations that the Company performs on its customers. As the Company continues to expand its sales internationally, it may experience increased levels of customer credit risk associated with those regions. Collateral is generally not required for accounts receivable but may be used in the future to mitigate credit risk associated with customers located in certain geographical regions.
One customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 31, 2022. No customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 25, 2021.
One customer accounted for approximately 11% of the Company's revenue in 2022 and 2020. No customer accounted for 10% or more of the Company's revenue in 2021.
The Company depends on sole source or limited source suppliers for several key components and raw materials. The Company generally purchases these sole source or limited source components and raw materials through standard purchase orders and does not have long-term contracts with many of these limited-source suppliers. While the Company seeks to maintain sufficient reserve stock of such components and raw materials, the Company’s business and results of operations could be adversely affected if any of its sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output.
Derivative Instruments
The Company is exposed to foreign currency exchange rate fluctuations in the normal course of its business. As part of its risk management strategy, the Company uses derivative instruments, specifically forward contracts, to reduce the impact of foreign exchange fluctuations on earnings. The forward contracts are with high-quality institutions and the Company monitors the creditworthiness of the counterparties consistently. The Company’s objective is to offset gains and losses resulting from these exposures with gains and losses on the derivative contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets. The Company does not use derivative contracts for trading or speculative purposes.
The Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuations in foreign exchange rates that arise primarily from euro and British pounds. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate changes on the underlying account balances, and therefore, do not subject the Company to material balance sheet risk.
The Company has entered into factoring agreements, to sell certain receivables to unrelated third-party financial institutions. These transactions are accounted for in accordance with ASC 860, Transfers and Servicing (“ASC 860”). ASC 860 and result in a reduction in accounts receivable because the agreements transfer effective control over and risk related to the receivables to the buyers. The Company's factoring agreements do not allow for recourse in the event of uncollectability, and the Company does not retain any interest in the underlying accounts receivable once sold.
Inventory Valuation
Inventories consist of raw materials, work-in-process and finished goods and are stated at standard cost adjusted to approximate the lower of actual cost or net realizable value. Costs are recognized utilizing the first-in, first-out method. Net realizable value is based upon an estimated selling price reduced by the estimated cost of disposal. The determination of market value involves numerous judgments including estimated average selling prices based upon recent sales volumes, industry trends, existing customer orders, current contract price, future demand and pricing and technological obsolescence of the Company’s products.
Inventory that is obsolete or in excess of the Company’s forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing its inventory costs and deferred inventory costs, the Company considered whether the net realizable value of inventory delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. The Company concluded that, in the instances where the net realizable value of inventory delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at cost or net realizable value, whichever is lower, thereby recognizing the cost of the reduction in net realizable value of inventory in the period in which the reduction occurred or can be reasonably estimated. The Company has, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of actual cost or net realizable value.
The Company considers whether it should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contractual purchase price, the Company has also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.
Property, Plant and Equipment
Property, plant and equipment are stated at cost. This includes enterprise-level business software that the Company customizes to meet its specific operational needs and certain software licenses. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. An assumption of lease renewal where a renewal option exists is used only when the renewal has been determined to be reasonably certain. Repair and maintenance costs are expensed as incurred. The estimated useful life for each asset category is as follows:
Estimated Useful Lives
Building
20 years
Laboratory and manufacturing equipment
1.5 to 10 years
Furniture and fixtures
3 to 5 years
Computer hardware
3 to 5 years
Computer software
3 years
Leasehold and building improvements
1 to 11 years
The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable or that the useful life is shorter than originally estimated. If impairment indicators are present and the projected future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. If assets are determined to be recoverable, but the useful lives are shorter than originally estimated, the carrying value of the assets is depreciated over the newly determined remaining useful lives.
Accrued Warranty
In the Company's contracts with its customers, the Company warrants that its products will operate substantially in conformity with product specifications. Hardware warranties provide the purchaser with protection in the event that the product does not perform to product specifications. During the warranty period, the purchaser’s sole and exclusive remedy in the event of such defect or failure to perform is limited to the correction of the defect or failure by repair, refurbishment or replacement, at the Company’s sole option and expense. The Company's hardware warranty periods generally range from one to five years from date of acceptance for hardware and the Company's software warranty is 90 days. Upon delivery of the Company's products, the Company provides for the estimated cost to repair or replace products that may be returned under warranty. The hardware warranty accrual is based on actual historical returns and cost of repair experience and the application of those historical rates to the Company's in-warranty installed base. The provision for warranty claims fluctuates depending upon the installed base of products and the failure rates and costs of repair associated with these products under warranty. Furthermore, the Company's costs of repair vary based on repair volume and its ability to repair, rather than replace, defective units. In the event that actual product failure rates and costs to repair differ from the Company's estimates, revisions to the warranty provision are required. In addition, from time to time, specific hardware warranty accruals may be made if unforeseen technical problems arise with specific products. The Company regularly assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.
Amortization of Intangible Assets
Intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. In-process research and development represent the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization, but once projects have been completed, these assets are transferred to developed technology, which are subject to amortization, while assets related to projects that have been abandoned are impaired and expensed to research and development.
Impairment of Goodwill and Intangible Assets
Goodwill represents the excess of the purchase price of an acquired business over the fair value of the identifiable assets acquired and liabilities assumed. The Company tests for impairment of goodwill on an annual
basis in the fourth quarter and at any other time when events occur or circumstances indicate that the carrying amount of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines that as a result of the qualitative assessment that it is more likely than not (i.e., greater than 50% likelihood) that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is required or it can directly perform the quantitative analysis. The Company recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized does not exceed the total amount of goodwill allocated to that reporting unit.
The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of these assets by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, the Company records an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Leases
The Company has operating leases primarily for real estate (facilities) and automobiles. The Company has finance leases primarily for computer hardware, laboratory and manufacturing equipment and leasehold and building improvements.
The Company leases facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 11 years and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to six years.
The Company determines if an arrangement contains a lease at inception. Operating leases are included in operating lease right of use ("ROU") assets, accrued expenses and other current liabilities and operating lease liabilities on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, net, accrued expenses and other current liabilities and other long-term liabilities on the Company's consolidated balance sheets.
Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. Operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. Variable lease payments are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company rents or subleases certain real estate under agreements that are classified as operating leases.
Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company does not account for lease components (e.g., fixed payments including rent) separately from the non-lease components (e.g., common-area maintenance costs).
Upon abandoning or committing to a plan to abandon a leased property in the short term before the lease term expires, the Company assesses the fair value of its remaining obligation under the lease and records an impairment of the ROU asset, if needed. The impairment loss is calculated as the present value of the amount by which the remaining lease obligation, adjusted for the effects of any one-time costs to sublease, exceeds the estimated sublease rentals that could be reasonably obtained. The estimated sublease rentals consider Company's ability and intent to sublease the space. The significant assumptions used in the Company's discounted cash flow model include the amount and timing of estimated sublease rental receipts and the discount rate which involve a number of risks and uncertainties, some of which are beyond control, including future real estate market conditions and the Company's ability to successfully enter into subleases or termination agreements with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.
The loss recorded or to be recorded may change significantly as a result of the re-measurement of the liability, if the timing or amount of estimated cash flows change.
Restructuring and Other Related Costs
The Company records costs associated with exit activities related to restructuring plans in accordance with ASC 420, Exit or Disposal Cost Obligations, or ASC 712, Compensation — Nonretirement Postemployment Benefits. Liabilities for costs associated with an exit or disposal activity are recognized in the period in which the liability is incurred. The timing of the associated cash payments is dependent upon the type of exit cost and extends over an approximately four-year period. The Company records restructuring cost liabilities in “accrued expenses and other current liabilities” and "other long-term liabilities" in the consolidated balance sheet.
Restructuring costs include employee and contract termination costs, facility consolidation and closure costs, lease related impairment charges, equipment write-downs and inventory write-downs. One-time termination benefits are recognized as a liability at estimated fair value when the approved plan of termination has been communicated to employees, unless employees must provide future service, in which case the benefits are recognized ratably over the future service period. Ongoing termination benefits arrangements are recognized as a liability at estimated fair value when the amount of such benefits becomes estimable and payment is probable.
Restructuring charges require significant estimates and assumptions, including estimates made for employee separation costs and other contract termination charges. Management estimates involve a number of risks and uncertainties, some of which are beyond control, including the Company's ability to successfully enter into termination agreements with employees and others with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.
Recent Accounting Pronouncements
Accounting Pronouncements Recently Adopted
In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for convertible instruments by removing certain separation models in ASC 470-20, Debt—Debt with Conversion and Other Options, for convertible instruments. On December 26, 2021, the Company adopted ASU 2020-06 using the modified retrospective method. Applying the transition guidance, the Company was required to apply the guidance to all impacted financial instruments that were outstanding as of December 26, 2021 with the cumulative effect recognized as an adjustment to the opening balance of accumulated deficit.
The adoption of ASU 2020-06 required the Company to record a $196.5 million reduction of additional paid in capital, on December 26, 2021, due to the recombination of the equity conversion component of convertible debt remaining outstanding, which was initially separated and recorded in equity. The $122.0 million increase in debt represented the removal of the remaining debt discounts recorded for this previous separation. The Company recognized a $74.5 million cumulative effect decrease of initially applying ASU 2020-06 as an adjustment to the December 26, 2021 opening balance of accumulated deficit. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible senior notes as a liability instrument. Since the Company had a net loss in 2022, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share in 2022 as a result of adopting ASU 2020-06. The prior period consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods.

Financial instruments that are not re-measured at fair value include accounts receivable, accounts payable, accrued liabilities, and debt. The carrying values of these financial instruments other than the Company's 2024 Notes, 2027 Notes and 2028 Notes (collectively referred to as "convertible senior notes" below) approximate their fair values. The fair value of each series of convertible senior notes was determined based on the quoted bid price of the applicable series of convertible senior notes in an over-the-counter market on December 30, 2022 (the last trading day of the fiscal quarter).

During 2022 and 2021, there were no transfers of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy. As of December 31, 2022 and December 25, 2021, none of the Company’s existing securities were classified as Level 3 securities.
The Company measures goodwill and intangible assets at fair value on a nonrecurring basis when there are identifiable events or changes in circumstances that may have a significant adverse impact on the fair value of these assets. The Company performed an analysis of impairment indicators of these assets and noted no adverse impact to their fair values as of December 31, 2022.
Facilities-related Charges
The Company classifies certain facilities-related charges within Level 3 of the fair value hierarchy and applies fair value accounting on a nonrecurring basis when impairment indicators exist or upon the existence of observable fair values. The fair values are classified as Level 3 measurements due to the significance of unobservable inputs. These analyses require management to make assumptions and estimates regarding industry and economic factors, future operating results and discount rates.
In connection with its Restructuring Plans (as defined in Note 9, “Restructuring and Other Related Costs” to the Notes to Consolidated Financial Statements), the Company incurred facilities related charges of
$8.1 million and $6.5 million for the years ended December 31, 2022 and December 25, 2021, respectively. These charges primarily consisted of impairment charges incurred for operating lease right-of-use assets and were calculated at fair value based on estimated future sublease rental receipts that the Company could reasonably obtain over the remaining lease term at the discount rate. Facilities-related charges are classified as Level 3 measurement due to the significance of these unobservable inputs.
Cash and Cash Equivalents
As of December 31, 2022, the Company had $189.2 million of cash, cash equivalents and restricted cash, including $65.9 million held by its foreign subsidiaries. As of December 25, 2021, the Company had $202.5 million of cash, cash equivalents and restricted cash including $77.6 million held by its foreign subsidiaries. The Company's cash held by its foreign subsidiaries is used for operating and investing activities in those locations, and the Company does not currently have the need or the intent to repatriate those funds to the United States.

Foreign Currency Exchange Forward Contracts
The Company transacts business in various foreign currencies and has international sales, cost of sales, and expenses denominated in foreign currencies, and carries foreign-currency-denominated account balances, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company utilizes foreign currency forward contracts, primarily short term in nature.
Historically, the Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuation in foreign exchange rates that arise from its euro and British pound denominated account balances. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate fluctuations on the underlying foreign currency denominated account balances, do not subject the Company to material balance sheet risk.
The Company had no outstanding foreign currency exchange forward contracts as of December 31, 2022. As of December 25, 2021, the Company had $29.5 million outstanding foreign currency exchange forward contract and posted collateral of $0.9 million to cover associated potential credit risk exposure. This collateral amount was classified as other long-term restricted cash on the accompanying consolidated balance sheets.
The before-tax effect of foreign currency exchange forward contracts was a gain of $0.6 million, $0.9 million and $0.3 million for 2022, 2021 and 2020, respectively, included in other income (expense), net, in the consolidated statements of operations. In each of these periods, the impact of the gross gains and losses were offset by foreign exchange rate fluctuations on the underlying foreign currency denominated amounts.
The Company does not designate foreign currency exchange forward contracts as hedges for accounting purposes and accordingly, changes in the fair value are recorded in the accompanying consolidated statements of operations. These contracts were with one high-quality institution and the Company consistently monitors the creditworthiness of the counterparties.
The fair value of derivative instruments not designated as hedging instruments in the Company’s consolidated balance sheets was as follows (in thousands):

Accounts Receivable Factoring
The Company sells certain designated trade account receivables based on factoring arrangements with well-established factoring companies. Pursuant to the terms of the arrangements, the Company accounts for these transactions in accordance with ASC 860. The Company's factor purchases trade accounts receivables on a non-recourse basis and without any further obligations. Trade accounts receivables balances sold are removed from the consolidated balance sheets and cash received are reflected as cash provided by operating activities in the consolidated statements of cash flow. The difference between the fair value of the Company's trade receivables and the proceeds received is recorded as interest expense in the Company's consolidated statements of operations. For the years ended December 31, 2022, December 25, 2021 and December 26, 2020, the Company's recognized factoring related interest expense was approximately $0.9 million, $0.4 million and $0.4 million, respectively. The gross amount of trade accounts receivables sold totaled approximately $101.0 million and $121.3 million for the fiscal years ended December 31, 2022 and December 25, 2021 respectively.

Restructuring and Related Activities [Abstract]

Restructuring and Other Related Costs Restructuring and Other Related Costs
In 2020, the Company implemented a restructuring initiative (the "2020 Restructuring Plan") that was primarily intended to reduce costs and consolidate its operations. The identified cost reduction initiatives under the 2020 Restructuring Plan were substantially completed, with the majority of associated payments made in 2020 and the remaining amounts substantially paid during 2021.
In 2021, the Company announced a plan to restructure certain international research & development operations (the "2021 Restructuring Plan"). The Company estimates it will incur total costs related to the restructuring ranging from $15.0 million to $17.0 million, of which $6.1 million and $8.5 million was recorded in
the fiscal years ended December 31, 2022 and December 25, 2021, respectively. The 2021 Restructuring Plan is substantially completed with the associated payments made in 2022. Additional restructuring activities may occur in the future in connection with the Company’s ongoing transformation initiatives.

Basic and Diluted Net Loss Per Common Share
12 Months Ended

Dec. 31, 2022

Earnings Per Share [Abstract]

Basic and Diluted Net Loss Per Common Share Basic and Diluted Net Loss Per Common ShareBasic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using net loss and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the assumed exercise of outstanding in-the-money stock options, assumed release of outstanding RSUs and PSUs, and assumed issuance of common stock under the ESPP using the treasury stock method. Potentially dilutive common shares also include the shares of common stock issuable upon conversion of the convertible senior notes using the if-converted method, as further discussed in Note 12, “Debt” to the Notes to Consolidated Financial Statements. The Company includes the common shares underlying PSUs in the calculation of diluted net income per common share only when they become contingently issuable.
The following table sets forth the computation of net loss per common share (in thousands, except per share amounts):
Years Ended
December 31, 2022 December 25, 2021 December 26, 2020
Net loss $ (76,043) $ (170,778) $ (206,723)

Net loss per common share - basic and diluted $ (0.35) $ (0.82) $ (1.10)
The Company incurred net losses during 2022, 2021 and 2020, and as a result, potential common shares from stock options, RSUs, PSUs and the assumed release of outstanding shares under the ESPP were not included in the diluted shares used to calculate net loss per share, as their inclusion would have been anti-dilutive. Additionally, due to the net loss position during these periods, the Company excluded the potential shares issuable upon conversion of the 2028 Notes, the 2027 Notes and the 2024 Notes in the calculation of diluted earnings per share, as their inclusion would have been anti-dilutive.
The following table sets forth the potentially dilutive shares excluded from the computation of the diluted net loss per share because their effect was anti-dilutive (in thousands):

Total 73,681 21,216 19,787
(1) The convertible senior notes were calculated under the if-converted method for 2022 due to the adoption of ASU 2020-06 and under the treasury stock method for 2021 and 2020.
Prior to the adoption of ASU 2020-06, the Company used the treasury stock method for calculating any potential dilutive effect of the conversion spread of its convertible senior notes. The conversion spread had a dilutive impact for the 2027 Notes during the fiscal year ended December 25, 2021 since the average market price of the Company’s common stock during the periods exceeded the initial conversion price of $7.66 per share. However, the potential shares of common stock issuable upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive.
After the adoption of ASU 2020-06, the Company used the if-converted method for calculating any potential dilutive effect of the convertible senior notes for fiscal year ended December 31, 2022. The Company calculates diluted earnings per share assuming that all of the convertible senior notes permitted to be share settled were converted solely into shares of common stock at the beginning of the reporting period. The potential impact upon the conversion of the convertible senior notes was excluded from the calculation of diluted net loss per share for the fiscal year ended December 31, 2022 because the effect would have been anti-dilutive.

Convertible Senior Notes
In September 2018, the Company issued $402.5 million aggregate principal amount of 2.125% Convertible Senior Notes due 2024 (the "2024 Notes"). In March 2020, the Company issued $200.0 million aggregate principal amount of 2.5% Convertible Senior Notes due 2027 (the “2027 Notes"). In August 2022, the Company issued $373.8 million aggregate principal amount of 3.75% Convertible Senior Notes due 2028 (the "2028 Notes," and, together with the 2024 Notes and 2027 Notes, the “convertible senior notes”). The 2024 Notes bear interest at a fixed rate of 2.125% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2019. The 2027 Notes bear interest at a fixed rate of 2.5% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2020. The 2028 Notes bear interest at a fixed rate of 3.75% per year, payable semi-annually in arrears on February 1 and August 1 of each year, beginning on February 1, 2023. Each series of the convertible senior notes is governed by an indenture between the Company, as the issuer, and U.S. Bank National Association, as Trustee (individually, each an “Indenture,” and together, the “Indentures”). The convertible senior notes of each series are unsecured and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the convertible senior notes; equal in right of payment to any of the Company's existing and future liabilities that are not so subordinated, effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s current or future subsidiaries. The applicable Indenture governing each series of the convertible senior notes does not contain any financial covenants or any restrictions on the payment of dividends, the incurrence of senior debt or other indebtedness, or the issuance or repurchase of the Company's other securities by the Company.
The net proceeds to the Company from the issuance of 2024 Notes were approximately $391.4 million, of which approximately $48.9 million was used to pay the cost of the capped call transactions with certain financial institutions (“Capped Calls”). The Company also used a portion of the remaining net proceeds to fund the cash portion of the purchase price of the Acquisition, including fees and expenses relating thereto, and used the remaining net proceeds for general corporate purposes.
The Capped Calls have an initial strike price of $9.87 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2024 Notes. The Capped Calls have initial cap prices of $15.19 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, 40.8 million shares of common stock. The Capped Calls transactions are expected generally to reduce or offset potential dilution to the Company's common stock upon any conversion of the 2024 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2024 Notes, as the case may be, with such reduction and/or offset subject to a cap. The Capped Calls expire on various dates between July 5, 2024 and August 29, 2024. The Capped Calls were recorded as a reduction of the Company’s stockholders’ equity in the accompanying consolidated balance sheets.
The net proceeds to the Company from the issuance of 2027 Notes were approximately $193.3 million after deducting initial purchasers' fee and other debt issuance costs. The Company used the remaining net proceeds for general corporate purposes, including working capital to fund growth and potential strategic projects.
The net proceeds to the Company from the issuance of 2028 Notes were approximately $362.4 million after deducting the initial purchasers' fee and other debt issuance costs. The Company used approximately $283.6 million, which included accrued and unpaid interest, of the net proceeds from this issuance to repurchase approximately $299.8 million in aggregate principal amount of its 2024 Notes concurrently with the issuance. This transaction involved a contemporaneous exchange of cash between the Company and holders of the 2024 Notes participating in the issuance of the 2028 Notes. Accordingly, the transaction was evaluated for modification or extinguishment accounting in accordance with ASC 470-50, Debt – Modifications and Extinguishments on a creditor-by creditor basis depending on whether the exchange was determined to have substantially different terms. The repurchase of the 2024 Notes and issuance of the 2028 Notes were deemed to have substantially different terms based on the present value of the cash flows or significant difference between the value of the conversion option immediately prior to and after the exchange. Therefore, the repurchase of the 2024 Notes was accounted for as a debt extinguishment. The Company recorded a $15.5 million gain on extinguishment of debt on its consolidated statements of operations during the fiscal year ended December 31, 2022, which includes the write-off of related deferred issuance costs of $3.5 million. After giving effect to the repurchase, the total remaining principal amount outstanding under the 2024 Notes as of December 31, 2022 was $102.7 million.
The Company intends to use the remaining net proceeds from the issuance of 2028 Notes for general corporate purposes, including working capital and to fund growth and potential strategic projects.
The 2024 Notes, the 2027 Notes and the 2028 Notes mature on September 1, 2024, March 1, 2027 and August 1, 2028, respectively. The Company did not have the right to redeem the 2024 Notes prior to September 5, 2021, and may not redeem the 2027 Notes prior to March 5, 2024 or the 2028 Notes prior to August 5, 2025. The Company may redeem for cash all or any portion of the 2024 Notes at its option, on or after September 5, 2021, the 2027 Notes, at its option, on or after March 5, 2024, and the 2028 Notes, at its option, on or after August 5, 2025, if the last reported sale price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the convertible senior notes.
Conversion Rate and Initial Conversion Price for each series of convertible senior notes are presented in the following table:
Conversion Rate per $1,000 Principal Initial Conversion Price
2024 Notes 101.2812 $ 9.87
2027 Notes 130.5995 $ 7.66
2028 Notes 147.1183 $ 6.80
Throughout the term of the convertible senior notes, the conversion rate may be adjusted upon the occurrence of certain events, including for any cash dividends. Holders of the convertible senior notes will not receive any cash payment representing accrued and unpaid interest upon conversion. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than canceled, extinguished or forfeited. Prior to the close of business on the business day immediately preceding June 1, 2024 for the 2024 Notes, December 1, 2026 for the 2027 Notes and May 1, 2028 for the 2028 Notes (the convertible dates), holders may convert their convertible senior notes under the following circumstances:
•during any fiscal quarter commencing after the fiscal quarters ended on December 29, 2018 for the 2024 Notes, June 27, 2020 for the 2027 Notes and September 24, 2022 for the 2028 Notes (and only during such fiscal quarter) if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
•during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the convertible senior notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;
•if the Company calls any or all of the convertible senior notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date;
•upon the occurrence of specified corporate events described under the Indentures, such as a consolidation, merger or binding share exchange;
•or at any time on or after respective convertible dates, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their convertible senior notes at any time, regardless of the foregoing circumstances.
Upon the receipt of conversion requests, the settlement of the convertible senior notes will be paid pursuant to the terms of the respective governing Indentures. In the event that any of the 2024 Notes and 2027 Notes are converted, the Company would be required to repay the principal amount and any conversion premium in any combination of cash and shares of its common stock at the Company’s option. In the event that any of the 2028 Notes are converted, the Company would be required to repay the principal amount in cash and the conversion premium in any combination of cash and shares of its common stock at the Company’s option.
If the Company undergoes a fundamental change as defined in the Indentures, holders may require the Company to repurchase for cash all or any portion of their convertible senior notes at a repurchase price equal to 100% of the principal amount of the convertible senior notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, upon the occurrence of a “make-whole fundamental change” (as defined in each of the Indentures), the Company may, in certain circumstances, be required to increase the conversion rate by a number of additional shares for a holder that elects to convert its convertible senior notes in connection with such make-whole fundamental change.
There have been no changes to the initial conversion price of the convertible senior notes since issuance. None of the conditions allowing holders of the convertible senior notes to convert early were met. The convertible senior notes were therefore not convertible during 2022.
Interest Expense
The following table presents the interest expense related to the contractual interest coupon, the amortization of debt issuance costs, and the amortization of debt discounts on our convertible senior notes (in thousands):
Year Ended
December 31, 2022 December 25, 2021 December 26, 2020
Contractual interest expense $ 16,589 $ 13,553 $ 12,577
Amortization of debt issuance costs 3,404 1,892 1,634
Amortization of debt discount — 29,411 25,349
Total interest expense $ 19,993 $ 44,856 $ 39,560
Adoption of ASU 2020-06
Prior to the adoption of ASU 2020-06 on December 26, 2021 and in accounting for the issuance of the convertible senior notes, the convertible senior notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The carrying amounts of the equity component representing the conversion option related to the 2024 Notes and 2027 Notes were $128.7 million and $67.8 million, respectively. This was determined by deducting the fair value of the liability component from its par value. The equity component was recorded in additional paid-in-capital and was not re-measured as long as it continued to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the “debt discount”) was amortized to interest expense over the respective contractual term of the convertible senior notes at an effective interest rate of 9.92%.
Prior to the adoption of ASU 2020-06 on December 26, 2021 and in accounting for the debt issuance costs of $12.9 million and $6.7 million related to the 2024 Notes and 2027 Notes, respectively, the Company allocated the total amount incurred to the liability and equity components of the convertible senior notes based on their relative values. Issuance costs attributable to the liability component were $8.7 million and $4.3 million, related to the 2024 Notes and 2027 Notes, respectively, and were amortized to interest expense using the effective interest method over the contractual term of the convertible senior notes. Issuance costs attributable to the equity component were netted with the equity component in additional paid-in-capital.
On December 26, 2021, the Company adopted ASU 2020-06 based on a modified retrospective transition method. Under such transition, prior-period information has not been retrospectively adjusted.
In accounting for the convertible senior notes after adoption of ASU 2020-06, the convertible senior notes are accounted for as a single liability. The issuance cost related to the 2024 Notes, the 2027 Notes and the 2028 Notes are being amortized to interest expense over the respective contractual term, at effective interest rates of 2.7%, 3.0% and 4.3%, respectively. Unamortized debt issuance costs will be amortized over the remaining life of the 2024 Notes, the 2027 Notes and the 2028 Notes which is approximately 20 months, 50 months, and 67 months, respectively.
The net carrying amount of the convertible senior notes as of December 31, 2022 (post-ASU 2020-06 adoption) and as of December 25, 2021 (pre-ASU 2020-06 adoption) was as follows (in thousands):
2024 Notes 2027 Notes 2028 Notes
December 31, 2022 December 25, 2021 December 31, 2022 December 25, 2021 December 31, 2022
Principal $ 102,652 $ 402,500 $ 200,000 $ 200,000 $ 373,750
Unamortized debt discount — (68,755) — (56,270) —
Unamortized issuance costs (926) (4,488) (4,121) (3,472) (10,401)
Net carrying amount $ 101,726 $ 329,257 $ 195,879 $ 140,258 $ 363,349
Asset-based revolving credit facility
On June 24, 2022, the Company entered into a Loan, Guaranty and Security Agreement (the “Loan Agreement”) with the lenders party thereto, and Bank of America, N.A., as agent. The Loan Agreement provides for a senior secured asset-based revolving credit facility of up to $200 million (the "Credit Facility"), which the Company may draw upon from time to time. The Company may increase the total commitments under the revolving credit facility by up to an additional $100 million, subject to certain conditions. In addition, the Loan Agreement provides for a $50 million letter of credit subfacility and a $20 million swingline loan facility.
The proceeds of the loans under the Loan Agreement may be used to pay the fees, costs, and expenses incurred in connection with the Loan Agreement, repay existing debt and for working capital and general corporate purposes, including to fund growth. The Credit Facility has a stated maturity date of June 24, 2027. Availability under the Credit Facility will be based upon periodic borrowing base certifications valuing certain inventory and accounts receivable, as reduced by certain reserves. The Credit Facility is secured by a first-priority security interest (subject to certain exceptions) in inventory, certain related assets, specified deposit accounts, and certain other accounts.
Outstanding borrowings accrue interest at floating rates plus an applicable margin of 1.25% to 1.75% for Term Secured Overnight Financing Rate ("SOFR") rate loans and 0.25% to 0.75% for base rate loans. The unused line fee rate payable on the unused portion of the Credit Facility is equal to 0.25% per annum based on utilization of the Credit Facility.
The Loan Agreement contains customary affirmative covenants, such as financial statement reporting requirements and delivery of borrowing base certificates. The Loan Agreement also contains customary covenants that limit the ability of the Company to, among other things, incur debt, create liens and encumbrances, engage in certain fundamental changes, dispose of assets, prepay certain indebtedness, make restricted payments, make investments, and engage in transactions with affiliates. The Loan Agreement also contains a financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio. As of December 31, 2022, the Company was in compliance with all covenants under the Loan Agreement.
In connection with the Credit Facility, the Company incurred lender and other third-party costs of approximately $1.2 million, which are recorded as a deferred asset and will be amortized to interest expense using a straight-line method over the term of the Credit Facility.
As of December 31, 2022, the Company had availability of $161.6 million under the Credit Facility. As of December 31, 2022, the Loan Agreement included a $50.0 million letter of credit subfacility and $15.4 million letters of credit issued and outstanding.
On August 1, 2019, the Company entered into a Credit Agreement with Wells Fargo Bank, N.A., (the "2019 Credit Agreement"), which was subsequently amended on December 23, 2019 (the "Amended Credit Agreement", and together with the 2019 Credit Agreement, the "Prior Credit Agreement"). The Prior Credit Agreement provided for a senior secured asset-based revolving credit facility of up to $150 million, which the Company could draw upon from time to time. The credit facility was secured by first-priority security interest
(subject to certain exceptions) in inventory, certain related assets, specified deposit accounts, and certain other accounts in certain domestic subsidiaries. The Prior Credit Agreement also provided for a $50 million letter of credit sub-facility and a $10 million swing loan sub-facility.
Outstanding borrowings under the Prior Credit Agreement accrued interest at floating rates plus and applicable margin from 2.00% to 2.50% for LIBOR rate loans and 1.00% to 1.50% for base rate loans, depending on the utilization of the credit facility. The commitment fee payable on the unused portion of the credit facility ranged from 0.375% to 0.625% per annum, also based on the utilization of the credit facility. The letter of credit accrued fee at a per annum rate equal to the applicable LIBOR rate margin times by the average amount of the letter of credit usage during the immediately preceding quarter, in addition to the fronting fees, commissions and other fees.
Effective January 1, 2022, with the cessation of LIBOR, the Prior Credit Agreement provided for an alternative benchmark rate for LIBOR-based loans, which included SOFR or other prevailing market rate as determined by the agent plus a spread based on prevailing market convention for the applicable interest period plus a margin ranging from 2.00% to 2.50%.
The Prior Credit Agreement contained customary affirmative covenants, such as financial statement reporting requirements and delivery of borrowing base certificates. It also contained customary covenants that limited the ability of the Company and its subsidiaries to, among other things, incur debt, create liens and encumbrances, engage in certain fundamental changes, dispose of assets, prepay certain indebtedness, make restricted payments, make investments, and engage in transactions with affiliates. In addition the Prior Credit Agreement also contained a financial covenant that required the Company to maintain a minimum amount of liquidity and customary events of default.
In connection with the Prior Credit Agreement, the Company incurred lender and other third-party costs of approximately $4.9 million in 2019, which were recorded as a deferred asset and are amortized to interest expense using a straight-line method over the term of the Prior Credit Agreement. As of December 25, 2021, the Prior Credit Agreement included a $50 million letter of credit facility and $11.5 million had been issued and outstanding.
In June 2022, the Company terminated the Prior Credit Agreement and repaid the entire outstanding principal balance of $40.0 million, in addition to accrued interest and other fees of $0.5 million. The Company also recorded $2.0 million in interest expense to write off the unamortized deferred debt issuance costs related to the Prior Credit Agreement.
Mortgage Payable
In March 2019, the Company mortgaged a property it owns. The Company received proceeds of $8.7 million in connection with the loan. The loan carries a fixed interest rate of 5.25% and is repayable in 59 equal monthly installments of principal and interest with the remaining unpaid principal balance plus accrued unpaid interest due five years from the date of the loan.
On September 24, 2021, the loan was amended to reduce the interest rate from 5.25% to 3.80% for the remaining 31 equal monthly installments of approximately $0.1 million, with the remaining principal payment at maturity date.

Legal Matters
NextGen Innovations, LLC
On August 9, 2022, NextGen Innovations, LLC ("NextGen") filed a complaint against us in the United States District Court for the Eastern District of Texas. The complaint asserts that through certain products we infringe on U.S. Patent Nos. 9,887,795, 10,263,723, and 10,771,181. The complaint alleges that NextGen is entitled to unspecified damages, costs, fees, expenses, interest, and injunctive relief. We are currently unable to predict the outcome of this litigation and therefore cannot reasonably estimate the possible loss or range of loss, if any, arising from this matter.
In addition to the matter described above, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material effect on our consolidated financial position, results of operations or cash flows.
Loss Contingencies
The Company is subject to the possibility of various losses arising in the ordinary course of business. These may relate to disputes, litigation and other legal actions. In the preparation of its quarterly and annual financial statements, the Company considers the likelihood of loss or the incurrence of a liability, including whether it is probable, reasonably possible or remote that a liability has been incurred, as well as the Company’s ability to reasonably estimate the amount of loss, in determining loss contingencies. In accordance with U.S. GAAP, an estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information to determine whether any accruals should be adjusted and whether new accruals are required. As of each of December 31, 2022 and December 25, 2021, the Company has accrued the estimated liabilities associated with certain loss contingencies.
Indemnification Obligations
From time to time, the Company enters into certain types of contracts that contingently require it to indemnify parties against third-party claims. The terms of such indemnification obligations vary. These contracts may relate to: (i) certain real estate leases under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; and (ii) certain agreements with the Company’s officers, directors and certain key employees, under which the Company may be required to indemnify such persons for liabilities.
In addition, the Company has agreed to indemnify certain customers for claims made against the Company’s products, where such claims allege infringement of third-party intellectual property rights, including, but not limited to, patents, registered trademarks, and/or copyrights. Under the aforementioned intellectual property indemnification clauses, the Company may be obligated to defend the customer and pay for the damages awarded against the customer under an infringement claim as well as the customer’s attorneys’ fees and costs. These indemnification obligations generally do not expire after termination or expiration of the agreement containing the indemnification obligation. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification. The Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements. The maximum potential amount of any future payments that the Company could be required to make under these indemnification obligations could be significant.
As permitted under Delaware law and the Company’s charter and bylaws, the Company has agreements whereby it indemnifies certain of its officers and each of its directors. The term of the indemnification period is for the officer’s or director’s lifetime for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements could be significant; however, the Company has a director and officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal.

Balance at the end of the period $ 36,621 $ 44,310
(1)The Company records product warranty liabilities based on the latest quality and cost information available as of the date the revenue is recorded. The changes in estimate shown here are due to changes in overall actual failure rates, the mix of new versus used units related to replacement of failed units, and changes in the estimated cost of repair and product recalls. As the Company's products mature over time, failure rates and repair costs associated with such products generally decline leading to favorable changes in warranty reserves.

Restricted Stock Units
Pursuant to the 2016 Plan, the Company has granted RSUs to employees and non-employee members of the Company's board of directors. All RSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date. The Company accounted for the fair value of the RSUs using the closing market price of the Company’s common stock on the date of grant. Amortization of stock-based compensation expense related to RSUs in 2022, 2021 and 2020 was approximately $54.1 million, $42.3 million and $36.1 million, respectively.
Performance Stock Units
Pursuant to the 2016 Plan, the Company has granted PSUs to certain of the Company’s executive officers, senior management and certain employees. All PSUs awarded are subject to each individual's continued service to the Company through each applicable vesting date and if the performance metrics are not met within the time limits specified in the award agreements, the PSUs will be canceled.
PSUs granted to the Company's executive officers and senior management under the 2016 Plan during 2020, 2021 and 2022 are based on performance criteria related to a specific financial target over the span of a three-year performance period. These PSUs may become eligible for vesting to begin before the end of the three-year performance period, if the applicable financial target is met. The number of shares to be issued upon vesting of these PSUs are capped at the target number of PSUs granted. Certain other employees were awarded PSUs that will only vest upon the achievement of specific financial and operational performance criteria.

Loss before provision for income taxes from international operations was $20.2 million, $20.7 million and $37.3 million for the years ended December 31, 2022, December 25, 2021 and December 26, 2020, respectively.
The provisions for income taxes differ from the amount computed by applying the statutory federal income tax rates as follows:
Years Ended
December 31, 2022 December 25, 2021 December 26, 2020
Expected tax at federal statutory rate 21.0 % 21.0 % 21.0 %
State taxes, net of federal benefit (2.2) % (1.2) % (0.4) %
Research credits 8.9 % 1.7 % 1.2 %

Nondeductible expenses (15.4) % — % — %
Other (6.0) % (2.3) % (0.4) %
Effective tax rate (37.1) % (7.5) % (3.0) %
For 2022, the Company's income tax expense was $20.5 million with effective tax rate of (37.1)%. The difference between the effective income tax rate and the U.S federal statutory rate of 21% to income before income taxes is primarily the result of R&D credits, stock-based compensation, foreign income taxed at different rates and valuation allowances. The Company recognized an income tax expense of $12.0 million and $6.0 million in 2021 and 2020, respectively. The resulting effective tax rates were (7.5)% and (3.0)% for 2021 and 2020, respectively. The 2021 and 2020 effective tax rates differ from the expected statutory rate of 21%, based on the Company's ability to benefit from its U.S. loss carryforwards, offset by state income taxes, non-deductible stock-based compensation expenses and foreign taxes provided on foreign subsidiary earnings.
During 2022, the Company implemented a realignment of its internal supply chain and customer facing entities. The new structure aligned and consolidated the Company's intellectual property and the associated commercial risk and reward among the customer-facing entities in their internal supply chain and improved operational efficiency. The impact of this internal realignment is reflected in the Company’s tax provision for the year ended December 31, 2022.
Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis using enacted tax rates in effect for the year in which the differences are expected to reverse. Significant deferred tax assets and liabilities consist of the following (in thousands):
Years Ended

Net deferred tax assets (liabilities) $ 2,035 $ (400)
The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company must consider all positive and negative evidence, including the Company's forecasts of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors in evaluating the need for a full or partial valuation allowance against its net U.S. deferred tax assets. Based on the available objective evidence, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the Company has provided a full valuation allowance against its domestic deferred tax assets, net of deferred tax liabilities, as of December 31, 2022 and December 25, 2021.
The Company intends to continue maintaining a full valuation allowance on its deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. However, considering the Company's current assessment of the probability of maintaining profitability, there is a reasonable possibility that, within the next year or two, sufficient positive evidence may become available to reach a conclusion that a portion of the valuation allowance will no longer be needed. As such, the Company may release a portion of its valuation allowance against its deferred tax assets within the next 12-24 months. This release, if
any, would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period such release is recorded.
Beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminated the right to deduct research and development expenditures for tax purposes in the period the expenses were incurred and instead requires all U.S. and foreign research and development expenditures to be amortized over five and fifteen tax years, respectively. Due to this required capitalization of research and development expenditures, the Company has recorded U.S. current income tax expense of $1.3 million for the year ended December 31, 2022. The U.S. current income tax provision is primarily for state taxes we anticipate paying as a result of statutory limitations on our ability to offset expected taxable income with net operating loss and research and development credit carry forwards. The increase in Federal taxable income due to R&D expense capitalization is offset by net operating carryover balance. It is expected that R&D expense capitalization will continue to generate Federal and State taxable income in future years and continue to utilize net operating loss and other available tax credits.
As of December 31, 2022, the Company had net operating loss carryforwards of approximately $507.0 million for federal income tax purposes which will begin to expire in 2032 if unused. The Company had net operating loss carryforwards of approximately $512.0 million for state income tax purposes which will begin to expire in the year 2023 if unused. The Company also had foreign net operating loss carryforwards of approximately $605.5 million, some of which will begin expiring in the year 2023 if unused.
As of December 31, 2022, the Company also had R&D credit carryforwards of approximately $49.3 million for federal income tax and $55.1 million for state income tax purposes. The federal R&D tax credit will begin to expire in 2023 if unused. State R&D tax credits will carry forward indefinitely.
As of December 31, 2022, the Company also had Foreign Tax credit carryforwards of approximately $38.9 million for federal income tax. The foreign tax credit will begin to expire in 2023 if unused.
Infinera Canada Inc., an indirect wholly owned subsidiary, has Scientific Research and Experimental Development Expenditures (“SRED”) credits available of $4.0 million to offset future Canadian income taxes payable as of December 31, 2022. Infinera Portugal subsidiary has a SIFIDE Credit of $4.3 million to offset future income tax payable in Portugal as of December 31, 2022. Canadian SRED credits will begin to expire in the year 2032 if not fully utilized. The Portugal SIFIDE credits will begin to expire in the year 2023.
At December 31, 2022, the Company had federal capital loss carryforwards of $19.6 million. If not utilized, the federal capital loss will expire in 2023.
The federal and state net operating loss carryforwards may be subject to significant limitations under Section 382 and Section 383 of the Internal Revenue Code of 1986, as amended (the "Code") and similar provisions under state law. The Tax Reform Act of 1986 contains provisions that limit the federal net operating loss carryforwards that may be used in any given year in the event of special occurrences, including significant ownership changes. The Company has completed a Section 382 review and has determined that none of its operating losses will expire solely due to Section 382 limitation(s).
The aggregate changes in the balance of gross unrecognized tax benefits were as follows (in thousands):
December 31, 2022 December 25, 2021 December 26, 2020
Beginning balance $ 54,250 $ 57,931 $ 44,092

Lapses of statute of limitations (325) (2,943) (243)
Ending balance $ 57,849 $ 54,250 $ 57,931
As of December 31, 2022, the cumulative unrecognized tax benefit was $57.8 million, of which $49.5 million was netted against deferred tax assets, which would have otherwise been subjected with a full valuation allowance. Of the total unrecognized tax benefit as of December 31, 2022, approximately $8.3 million, if recognized, would impact the Company’s effective tax rate. The amount of unrecognized tax benefit could be reduced upon expiration of the applicable statute of limitation. The potential reduction in unrecognized tax benefits during the next 12 months is not expected to be material.
As of December 31, 2022, December 25, 2021 and December 26, 2020, the Company had $1.3 million, $2.1 million and $2.9 million, respectively, of accrued interest or penalties related to unrecognized tax benefits, of which $0.8 million was included in the Company’s provision for income taxes in each of the years ended December 31, 2022, December 25, 2021 and December 26, 2020, respectively. The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the Company’s provision for income taxes.
The Company is potentially subject to examination by the Internal Revenue Service and the relevant state income taxing authorities under the statute of limitations for years 2003 and forward.
Included in the balance of income tax liabilities, accrued interest and penalties at December 31, 2022 is an immaterial amount related to tax positions for which it is reasonably possible that the statute of limitations will expire in various jurisdictions within the next twelve months.
Post U.S. Tax Reform, the Company and its subsidiaries do not have significant unremitted foreign earnings and the associated withholding and other taxes are not material for the fiscal year ended December 31, 2022.

Employee Benefit and Pension Plans Employee Benefit and Pension Plans
Defined Contribution Plans
The Company has established a savings plan under Section 401(k) of the Code (the “401(k) Plan”). As allowed under Section 401(k) of the Code, the 401(k) Plan provides tax-deferred salary contributions for eligible U.S. employees. Employee contributions are limited to a maximum annual amount as set periodically by the Code. The Company made voluntary cash contributions and matched a portion of employee contributions of $3.0 million, $2.8 million and $2.4 million for 2022, 2021, and 2020, respectively. Expenses related to the 401(k) Plan were insignificant for each of the years 2022, 2021, and 2020.
The Company has an ITP pension plan covering its Swedish employees. Commitments for old-age and survivors' pension for salaried employees in Sweden are vested through an insurance policy. Expenses related to the ITP pension plan were $2.5 million for 2022, $2.8 million for 2021 and $2.7 million for 2020.
The Company also provides defined contribution plans in certain foreign countries where required by local statute or at the Company's discretion. For the years ended December 31, 2022, December 25, 2021 and December 26, 2020, the Company had $4.9 million, $6.2 million, and $3.5 million related to post-retirement costs, respectively.
Pension Plans
Pension and Post-Retirement Benefit Plans
The Company has a number of post-employment plans in Germany, as well as a number of smaller post-employment plans in other countries, including both defined contribution and defined benefit plans. The defined benefit plans expose the Company to actuarial risks such as, investment risk, interest rate risk, life expectancy risk and salary risk. The characteristics of the defined benefit plans and the risks associated with them vary depending on legal, fiscal, and economic requirements.

Components of Net Periodic Benefit Cost
Net periodic benefit cost for the Company's pension and other post-retirement benefit plans consisted of the following (in thousands):
Years ended
December 31, 2022 December 25, 2021 December 26, 2020
Service cost $ 300 $ 351 $ 896

Total net periodic (benefit) cost $ (1,061) $ 2,104 $ 1,909
Actuarial gains and losses are amortized using a corridor approach. The gain/loss corridor is equal to 10% of the greater of the pension benefit obligation and the market-related value of assets. Gains and losses in excess of the corridor are generally amortized over the average future working lifetime of the pension plan participants. The service cost component is included in operating expenses in the Company's consolidated statements of operations. All other components are included in Other income (expense), net in the Company's consolidated statements of operations.
The following table sets forth the changes in accumulated other comprehensive income (loss) for the Company's benefit plans (pre-tax) (in thousands):
December 31, 2022 December 25, 2021

Ending balance $ 27,161 $ 4,297
(1)    The actuarial gain for the fiscal years ended December 31, 2022 and December 25, 2021 is primarily due to the change in the discount rate. Amounts recorded in accumulated other comprehensive income (loss) expected to be amortized as a part of net periodic pension cost during 2023 is $3.7 million (pre-tax).
Assumptions
Certain actuarial assumptions used in computing the benefit obligations for the major plans are as follows:
December 31, 2022 December 25, 2021
Discount rate 4.17 % 1.20 %
Salary growth rate 2.50 % 2.25 %
Pension growth rate 2.25 % 2.00 %
Expected long-term rate of return on plan assets 3.93 % 3.93 %
Investment Policy
The financial position of the Company’s funded status is the difference between the fair value of plan assets and projected benefit obligations. Volatility in funded status occurs when asset values change differently from liability values and can result in fluctuations in costs in financial reporting. The Company’s investment policies and strategies are designed to increase the rate of assets to plan liabilities at an appropriate level of funded status volatility. Asset allocation decisions are recommended by the trustees for the specific plan and agreed to by the Company's management. Investment objectives are designed to generate returns that will enable the plan to meet its future obligations. The Company's management reviews the investment strategy and performance semi-annually and discuss alternatives to manage volatility.
Basis for Expected Long-Term Rate of Return on Plan Assets
The expected long-term rate of return on plan assets reflects the expected returns for each major asset class in which the plan invests and the weight of each asset class in the target mix. Expected asset returns reflect the current yield on government bonds, risk premiums for each asset class and expected real returns which considers each country’s specific inflation outlook. The expected return is set using a low to medium risk profile and to meet the market expectations over a longer period of time to meet the obligations in the future.
Fair Value of Plan Assets
The following tables present the fair value of plan assets for pension and other benefit plans by major asset category (in thousands):

Accounting Policies [Abstract]

Use of Estimates
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, assumptions and judgments that can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. Estimates, assumptions and judgements made by management include inventory valuation, revenue recognition, accounting for income taxes, stock-based compensation, employee benefit and pension plans, manufacturing partner and supplier liabilities, allowances for sales returns, allowances for credit losses, useful life of intangibles and property, plant and equipment, impairment loss related to lease abandonment, accrued warranty, operating and finance lease liabilities, restructuring and other related costs and loss contingencies. The Company bases its assumptions on historical experience and also on assumptions that it believes are reasonable. Actual results could differ materially from those estimates. These estimates may change as new events occur and additional information emerges, and such changes are recognized or disclosed in the Company's consolidated financial statements.

Revenue Recognition
Revenue Recognition
The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.
The Company determines revenue recognition by applying the following five-step approach:
•identification of the contract, or contracts, with a customer;
•identification of the performance obligations in the contract;
•determination of the transaction price;
•allocation of the transaction price to the performance obligations in the contract; and
•recognition of revenue when, or as, the Company satisfies a performance obligation.
Many of the Company's product sales are sold in combination with installation and deployment services along with initial hardware and software support. The Company's product sales are also sold at times with spares management, on-site hardware replacement services, network operations management, software subscription services, extended hardware warranty and training. Initial software and hardware support services are generally delivered over a one-year period in connection with the initial purchase. Software warranty provides customers with maintenance releases during the warranty support period and hardware warranty provides replacement or repair of equipment that fails to perform in line with specifications. Software subscription services include software warranty and additionally provides customers with rights to receive unspecified software product upgrades released during the support period.
Spares management and on-site hardware replacement services include the replacement of defective units at customer sites in accordance with specified service level agreements. Network operations management includes the day-to-day operation of a customer's network. These services are generally delivered on an annual basis. The Company evaluates each promised good and service in a contract to determine whether it represents a distinct performance obligation or should be accounted for as a combined performance obligation.
Services revenue includes software subscription services, installation and deployment services, spares management, on-site hardware replacement services, network operations management, extended hardware warranty and training. Revenue from software subscription services, spares management, on-site hardware replacement services, network operations management and extended hardware warranty contracts is deferred and is recognized ratably over the contractual support period, which is generally one year, as services are provided over the course of the entire period. Revenue related to training and installation and deployment services is recognized upon completion of the services.
Contracts and customer purchase orders are generally used to determine the existence of an arrangement. In addition, shipping documents and customer acceptances, when applicable, are used to verify delivery and transfer of title. The Company typically satisfies its performance obligations upon shipment or delivery of product depending on the contractual terms. Payment terms to customers generally range from net 30 to 120 days from invoice, which are considered to be standard payment terms. The Company assesses its ability to collect from its customers based primarily on the creditworthiness and past payment history of the customer.
For sales to resellers, the same revenue recognition criteria apply. It is the Company’s practice to identify an end-user prior to shipment to a reseller. The Company does not offer rights of return or price protection to its resellers.
The Company reports revenue net of any required taxes collected from customers and remitted to government authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
Customer Purchase Commitments
The Company sells software licenses that provide customers the ability to purchase incremental bandwidth capacity on an already-deployed piece of hardware. Infinera Instant Bandwidth-enabled systems generally include a specific initial capacity and incremental capacity can be added by the purchase of Instant Bandwidth licenses. Instant Bandwidth licenses are considered distinct performance obligations because customers can provision additional transmission capacity on demand without the deployment of any incremental equipment.
Some contracts commit the customer to purchase incremental Instant Bandwidth licenses within a specified time frame from the initial shipment of the Instant Bandwidth-enabled hardware. The time frame varies by customer and generally ranges between 12 to 24 months. If the customer does not purchase the additional capacity within the time frame as stated in the contract, the Company has the right to deliver and invoice such Instant Bandwidth licenses to the customer. Future committed licenses are considered to be additional performance obligations when a minimum purchase obligation is present, as evidenced by enforceable rights and obligations. As such, the Company is required to estimate the variable consideration for future Instant Bandwidth licenses as part of determining the contract transaction price.
Contract Termination Rights
The contract term is determined on the basis of the period over which the parties to the contract have present enforceable rights and obligations. Certain customer contracts include a termination for convenience clause that allows the customer to terminate services without penalty, upon advance notification. For such contracts, the service duration is limited to the non-cancelable portion of the contract.
Variable Consideration
The consideration associated with customer contracts is generally fixed. Variable consideration includes discounts, rebates, refunds, credits, incentives, penalties, or other similar items. The amount of consideration that can vary is not a substantial portion of total consideration.
Variable consideration estimates are re-assessed at each reporting period until a final outcome is determined. The changes to the original transaction price due to a change in estimated variable consideration will be applied on a retrospective basis, with the adjustment recorded in the period in which the change occurs.
Stand-alone Selling Price
Stand-alone selling price is the price at which an entity would sell a good or service on a stand-alone (or separate) basis at contract inception. Under this model, the observable price of a good or service sold separately provides the best evidence of stand-alone selling price. However, in certain situations, stand-alone selling prices will not be readily observable and the entity must estimate the stand-alone selling price.
When allocating on a relative stand-alone selling price basis, any discount provided in the contract is generally allocated proportionately to all of the performance obligations in the contract.
The majority of products and services offered by the Company have readily observable selling prices. For products and services that do not, the Company generally estimates stand-alone selling price using the market assessment approach based on expected selling price and adjust those prices as necessary to reflect the Company’s costs and margins. As part of its stand-alone selling price policy, the Company reviews product pricing on a periodic basis to identify any significant changes and revise its expected stand-alone selling price assumptions as appropriate.
Shipping and Handling
The Company treats shipping and handling activities as costs to fulfill the Company's promise to transfer products. Shipping and handling fees billed to customers are recorded as a reduction to cost of product.
Capitalization of Costs to Obtain a Contract
The Company has assessed the treatment of costs to obtain or fulfill a contract with a customer. Sales commissions have historically been expensed as incurred. Under Topic 606, the Company capitalizes sales commissions related to multi-year service contracts, which are paid for upfront, and amortizes the asset over the period of benefit, which is the service period. Sales commissions paid on service contract renewals, are commensurate with the sales commissions paid on the initial contracts.
Transaction Price Allocated to the Remaining Performance Obligation
The Company’s remaining performance obligations represent the transaction price allocated to performance obligations that are unsatisfied or partially satisfied as of period end, consisting of deferred revenue and backlog. The Company’s backlog represents purchase orders received from customers for future product shipments and services that are unsatisfied or partially satisfied as of period end. The Company’s backlog is subject to future events that could cause the amount or timing of the related revenue to change, and, in certain cases, may be canceled without penalty. Orders in backlog may be fulfilled several quarters following receipt or may relate to multi-year support service obligations.

Stock-Based Compensation
Stock-Based Compensation
Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period (generally the vesting period) under the straight-line amortization method. The Company accounts for forfeitures as they occur.
The Company estimates the fair value of the rights to acquire stock under its 2007 Employee Stock Purchase Plan (the “ESPP”) using the Black-Scholes option pricing formula. The ESPP provides for consecutive six-month offering periods and the Company's historical volatility data in the valuation of shares that are purchased under the ESPP.
The Company accounts for the fair value of restricted stock units (“RSUs”) using the closing market price of the Company’s common stock on the date of grant. For new-hire grants, RSUs typically vest ratably on an annual basis over four years. For annual refresh grants, RSUs typically vest ratably over 18 months to three years.
Performance Stock Units ("PSUs") granted to the Company's executive officers and senior management during 2019, 2020, 2021 and 2022 are based on performance criteria related to specific financial targets over the span of a two or three-year performance period. These PSUs may become eligible for vesting to begin before the end of the applicable performance period, if the applicable financial target is met. The number of shares to be issued upon vesting of these PSUs is capped at the target number of PSUs granted. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.
In addition, the Company granted other PSUs to certain employees that only vest upon the achievement of specific operational performance criteria. The Company assesses the achievement status of these PSUs on a quarterly basis and records the related stock-based compensation expenses based on the estimated achievement payout.

Employee Benefit and Pension Plans
Employee Benefit and Pension Plans
The Company operates a number of post-employment plans in Germany, as well as smaller post-employment plans in other countries, including both defined contribution and defined benefit plans. Benefit cost and obligations pertaining to these plans are based on assumptions for the discount rate, expected return on plan assets, mortality rates, expected salary increases, health care cost trend rates and attrition rates. The discount rate assumption is based on current investment yields of high-quality fixed-income securities with maturities similar to the expected benefits payment period. Mortality rates help predict the expected life of plan participants. The expected increase in the compensation levels assumption reflects the Company's actual experience and future expectations. The expected long-term return on plan assets is determined based on asset allocations, historical portfolio results, historical asset correlations and management’s expected returns for each asset class. The Company evaluates its expected return assumptions annually including reviewing current capital market assumptions to assess the reasonableness of the expected long-term return on plan assets. The Company updates the expected long-term return on assets when the Company observes a sufficient level of evidence that would suggest the long-term expected return has changed.

Research and Development
Research and Development
All costs to develop the Company’s hardware products are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company’s software products are released soon after technological feasibility has been established. As a result, costs subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.

Advertising AdvertisingAll advertising costs are expensed as incurred.

Accounting for Income Taxes
Accounting for Income Taxes
As part of the process of preparing its consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax expense together with assessing temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included in consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in consolidated statements of operations become deductible expenses under applicable income tax laws or loss, or credit carryforwards are utilized. Accordingly, realization of deferred tax assets is dependent on future taxable income within the respective jurisdictions against which these deductions, losses and credits can be utilized within the applicable future periods.
The Company must assess the likelihood that some portion or all of its deferred tax assets will be recovered from future taxable income within the respective jurisdictions, and to the extent the Company believes that recovery does not meet the “more-likely-than-not” standard, it must establish a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities and any valuation allowance
recorded against our net deferred tax assets. In evaluating the need for a full or partial valuation allowance, all positive and negative evidence must be considered, including the Company's forecast of taxable income over the applicable carryforward periods, its current financial performance, its market environment, and other factors. Based on the available objective evidence, at December 31, 2022, management believes it is not more likely than not that the domestic net deferred tax assets will be realizable in the foreseeable future. Accordingly, the domestic net deferred tax assets are subject to a full valuation allowance. To the extent that the Company determines that deferred tax assets are realizable on a more likely than not basis, and an adjustment is needed, that adjustment will be recorded in the period that the determination is made.
During 2022, the Company executed an internal realignment of its supply chain and customer-facing entities. Among other things, the new structure aligned and consolidated the exploitation of its intellectual property and the allocation of the associated commercial risk and reward with the customer-facing entities that manage its supply chain. The impact of this internal realignment is reflected in the Company’s tax provision for the year ended December 31, 2022.

Foreign Currency Translation and Transactions
Foreign Currency Translation and Transactions
The Company considers the functional currencies of its foreign subsidiaries to be the local currency. Assets and liabilities recorded in foreign currencies are translated at the exchange rate as of the balance sheet date, revenue, costs and expenses are translated at average exchange rates in effect during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets and consolidated statements of comprehensive income (loss).
For all non-functional currency account balances, the re-measurement of such balances to the functional currency will result in either a foreign exchange transaction gain or loss, which is recorded to other income (loss), net, in the Company's consolidated statement of operations, in the same period that the re-measurement occurred. Aggregate foreign exchange transactions recorded was gain of $12.8 million in 2022 and losses of $17.2 million and $0.2 million, in 2021 and 2020, respectively.
The Company enters into foreign currency exchange forward contracts to reduce the impact of foreign exchange fluctuations on earnings from certain non-functional currency account balances denominated primarily in euros and British pounds.

Cash and Cash Equivalents
Cash and Cash Equivalents
Cash consists primarily of cash in bank deposit accounts which, at times, a portion may exceed federally insured limits. The Company has not experienced any losses in such accounts.
The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Fair Value Measurement
Fair Value Measurement
Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.
Valuation techniques used by the Company are based upon observable and unobservable inputs. Observable or market inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about market participant assumptions based on the best information available. Observable inputs are the preferred source of values. These two types of inputs create the following fair value hierarchy:
Level 1 – Quoted prices in active markets for identical assets or liabilities.
Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 – Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.
The Company measures its cash equivalents, foreign currency exchange forward contracts and debt securities at fair value and classifies them in accordance with the fair value hierarchy on a recurring basis.
Foreign Currency Exchange Forward Contracts
As discussed in Note 6, “Derivative Instruments" to the Notes to Consolidated Financial Statements, the Company historically held non-speculative foreign exchange forward contracts to hedge certain foreign currency exchange exposures. The Company estimates the fair values of derivatives based on quoted market prices or pricing models using current market rates. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies.
Facilities-related Charges
The Company estimates the fair value of its facilities-related charges associated with its restructuring plans, based on estimated future discounted cash flows and unobservable inputs, which includes the amount and timing of estimated sublease rental receipts that the Company can reasonably obtain over the remaining lease term and the discount rate.

Accounts Receivable and Allowances for Credit Losses
Accounts Receivable and Allowances for Credit Losses
Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for estimated credit losses resulting from the inability of its customers to make required payments and reviewed the allowance quarterly. The Company determines expected credit losses by performing credit evaluations of its customers' financial condition, establishing both a general reserve and specific reserve for customers in adverse financial condition and adjusting for its expectations of changes in conditions that may impact the collectability of outstanding receivables. The Company considers a customer's receivable balance past due when the amount is due beyond the credit terms extended, The Company considers factors such as historical experience, credit quality, age of the accounts receivable balances, and geographic or country-specific risks. Amounts are written off when receivables are determined to be uncollectible.

Allowances for Sales Returns Allowances for Sales ReturnsCustomer product returns are approved on a case by case basis. Specific reserve provisions are made based upon a specific review of all the approved product returns where the customer has yet to return the products to generate the related sales return credit at the end of a period. Estimated sales returns are provided for as a reduction to revenue.

Concentration of Risk
Concentration of Risk
Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents and restricted cash, foreign exchange contracts and accounts receivable.
The risk with respect to foreign exchange contracts is mitigated by entering into these contracts with a large high-quality financial institution and the Company monitors the creditworthiness of the counterparty consistently.
The risk with respect to accounts receivable is mitigated by ongoing credit evaluations that the Company performs on its customers. As the Company continues to expand its sales internationally, it may experience increased levels of customer credit risk associated with those regions. Collateral is generally not required for accounts receivable but may be used in the future to mitigate credit risk associated with customers located in certain geographical regions.
One customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 31, 2022. No customer accounted for over 10% of the Company's accounts receivable balance, net on the consolidated balance sheets as of December 25, 2021.
One customer accounted for approximately 11% of the Company's revenue in 2022 and 2020. No customer accounted for 10% or more of the Company's revenue in 2021.
The Company depends on sole source or limited source suppliers for several key components and raw materials. The Company generally purchases these sole source or limited source components and raw materials through standard purchase orders and does not have long-term contracts with many of these limited-source suppliers. While the Company seeks to maintain sufficient reserve stock of such components and raw materials, the Company’s business and results of operations could be adversely affected if any of its sole source or limited source suppliers suffer from capacity constraints, lower than expected yields, deployment delays, work stoppages or any other reduction or disruption in output.

Derivative Instruments Derivative Instruments
The Company is exposed to foreign currency exchange rate fluctuations in the normal course of its business. As part of its risk management strategy, the Company uses derivative instruments, specifically forward contracts, to reduce the impact of foreign exchange fluctuations on earnings. The forward contracts are with high-quality institutions and the Company monitors the creditworthiness of the counterparties consistently. The Company’s objective is to offset gains and losses resulting from these exposures with gains and losses on the derivative contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets. The Company does not use derivative contracts for trading or speculative purposes.
The Company enters into foreign currency exchange forward contracts to manage its exposure to fluctuations in foreign exchange rates that arise primarily from euro and British pounds. Gains and losses on these contracts are intended to offset the impact of foreign exchange rate changes on the underlying account balances, and therefore, do not subject the Company to material balance sheet risk.
The Company has entered into factoring agreements, to sell certain receivables to unrelated third-party financial institutions. These transactions are accounted for in accordance with ASC 860, Transfers and Servicing (“ASC 860”). ASC 860 and result in a reduction in accounts receivable because the agreements transfer effective control over and risk related to the receivables to the buyers. The Company's factoring agreements do not allow for recourse in the event of uncollectability, and the Company does not retain any interest in the underlying accounts receivable once sold.

Inventory Valuation
Inventory Valuation
Inventories consist of raw materials, work-in-process and finished goods and are stated at standard cost adjusted to approximate the lower of actual cost or net realizable value. Costs are recognized utilizing the first-in, first-out method. Net realizable value is based upon an estimated selling price reduced by the estimated cost of disposal. The determination of market value involves numerous judgments including estimated average selling prices based upon recent sales volumes, industry trends, existing customer orders, current contract price, future demand and pricing and technological obsolescence of the Company’s products.
Inventory that is obsolete or in excess of the Company’s forecasted demand or is anticipated to be sold at a loss is written down to its estimated net realizable value based on historical usage and expected demand. In valuing its inventory costs and deferred inventory costs, the Company considered whether the net realizable value of inventory delivered or expected to be delivered at less than cost, primarily comprised of common equipment, had declined. The Company concluded that, in the instances where the net realizable value of inventory delivered or expected to be delivered was less than cost, it was appropriate to value the inventory costs and deferred inventory costs at cost or net realizable value, whichever is lower, thereby recognizing the cost of the reduction in net realizable value of inventory in the period in which the reduction occurred or can be reasonably estimated. The Company has, therefore, recognized inventory write-downs as necessary in each period in order to reflect inventory at the lower of actual cost or net realizable value.
The Company considers whether it should accrue losses on firm purchase commitments related to inventory items. Given that the net realizable value of common equipment is below contractual purchase price, the Company has also recorded losses on these firm purchase commitments in the period in which the commitment is made. When the inventory parts related to these firm purchase commitments are received, that inventory is recorded at the purchase price less the accrual for the loss on the purchase commitment.

Property, Plant and Equipment
Property, Plant and Equipment
Property, plant and equipment are stated at cost. This includes enterprise-level business software that the Company customizes to meet its specific operational needs and certain software licenses. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. An assumption of lease renewal where a renewal option exists is used only when the renewal has been determined to be reasonably certain. Repair and maintenance costs are expensed as incurred. The estimated useful life for each asset category is as follows:
Estimated Useful Lives
Building
20 years
Laboratory and manufacturing equipment
1.5 to 10 years
Furniture and fixtures
3 to 5 years
Computer hardware
3 to 5 years
Computer software
3 years
Leasehold and building improvements
1 to 11 years
The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable or that the useful life is shorter than originally estimated. If impairment indicators are present and the projected future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. If assets are determined to be recoverable, but the useful lives are shorter than originally estimated, the carrying value of the assets is depreciated over the newly determined remaining useful lives.

Accrued Warranty
Accrued Warranty
In the Company's contracts with its customers, the Company warrants that its products will operate substantially in conformity with product specifications. Hardware warranties provide the purchaser with protection in the event that the product does not perform to product specifications. During the warranty period, the purchaser’s sole and exclusive remedy in the event of such defect or failure to perform is limited to the correction of the defect or failure by repair, refurbishment or replacement, at the Company’s sole option and expense. The Company's hardware warranty periods generally range from one to five years from date of acceptance for hardware and the Company's software warranty is 90 days. Upon delivery of the Company's products, the Company provides for the estimated cost to repair or replace products that may be returned under warranty. The hardware warranty accrual is based on actual historical returns and cost of repair experience and the application of those historical rates to the Company's in-warranty installed base. The provision for warranty claims fluctuates depending upon the installed base of products and the failure rates and costs of repair associated with these products under warranty. Furthermore, the Company's costs of repair vary based on repair volume and its ability to repair, rather than replace, defective units. In the event that actual product failure rates and costs to repair differ from the Company's estimates, revisions to the warranty provision are required. In addition, from time to time, specific hardware warranty accruals may be made if unforeseen technical problems arise with specific products. The Company regularly assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Amortization of Intangible Assets Amortization of Intangible AssetsIntangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. In-process research and development represent the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization, but once projects have been completed, these assets are transferred to developed technology, which are subject to amortization, while assets related to projects that have been abandoned are impaired and expensed to research and development.

Impairment of Goodwill and Intangible Assets
Impairment of Goodwill and Intangible Assets
Goodwill represents the excess of the purchase price of an acquired business over the fair value of the identifiable assets acquired and liabilities assumed. The Company tests for impairment of goodwill on an annual
basis in the fourth quarter and at any other time when events occur or circumstances indicate that the carrying amount of goodwill may not be recoverable. The Company has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines that as a result of the qualitative assessment that it is more likely than not (i.e., greater than 50% likelihood) that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is required or it can directly perform the quantitative analysis. The Company recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized does not exceed the total amount of goodwill allocated to that reporting unit.The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of these assets by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, the Company records an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Leases
Leases
The Company has operating leases primarily for real estate (facilities) and automobiles. The Company has finance leases primarily for computer hardware, laboratory and manufacturing equipment and leasehold and building improvements.
The Company leases facilities under non-cancelable operating lease agreements. These leases have varying terms that range from one to 11 years and contain leasehold improvement incentives, rent holidays and escalation clauses. In addition, some of these leases have renewal options for up to six years.
The Company determines if an arrangement contains a lease at inception. Operating leases are included in operating lease right of use ("ROU") assets, accrued expenses and other current liabilities and operating lease liabilities on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, net, accrued expenses and other current liabilities and other long-term liabilities on the Company's consolidated balance sheets.
Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. Operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. Variable lease payments are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company rents or subleases certain real estate under agreements that are classified as operating leases.
Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company does not account for lease components (e.g., fixed payments including rent) separately from the non-lease components (e.g., common-area maintenance costs).
Upon abandoning or committing to a plan to abandon a leased property in the short term before the lease term expires, the Company assesses the fair value of its remaining obligation under the lease and records an impairment of the ROU asset, if needed. The impairment loss is calculated as the present value of the amount by which the remaining lease obligation, adjusted for the effects of any one-time costs to sublease, exceeds the estimated sublease rentals that could be reasonably obtained. The estimated sublease rentals consider Company's ability and intent to sublease the space. The significant assumptions used in the Company's discounted cash flow model include the amount and timing of estimated sublease rental receipts and the discount rate which involve a number of risks and uncertainties, some of which are beyond control, including future real estate market conditions and the Company's ability to successfully enter into subleases or termination agreements with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.
The loss recorded or to be recorded may change significantly as a result of the re-measurement of the liability, if the timing or amount of estimated cash flows change.

Restructuring and Other Related Costs
Restructuring and Other Related Costs
The Company records costs associated with exit activities related to restructuring plans in accordance with ASC 420, Exit or Disposal Cost Obligations, or ASC 712, Compensation — Nonretirement Postemployment Benefits. Liabilities for costs associated with an exit or disposal activity are recognized in the period in which the liability is incurred. The timing of the associated cash payments is dependent upon the type of exit cost and extends over an approximately four-year period. The Company records restructuring cost liabilities in “accrued expenses and other current liabilities” and "other long-term liabilities" in the consolidated balance sheet.
Restructuring costs include employee and contract termination costs, facility consolidation and closure costs, lease related impairment charges, equipment write-downs and inventory write-downs. One-time termination benefits are recognized as a liability at estimated fair value when the approved plan of termination has been communicated to employees, unless employees must provide future service, in which case the benefits are recognized ratably over the future service period. Ongoing termination benefits arrangements are recognized as a liability at estimated fair value when the amount of such benefits becomes estimable and payment is probable.
Restructuring charges require significant estimates and assumptions, including estimates made for employee separation costs and other contract termination charges. Management estimates involve a number of risks and uncertainties, some of which are beyond control, including the Company's ability to successfully enter into termination agreements with employees and others with terms as favorable as those assumed when arriving at its estimates. The Company monitors these estimates and assumptions on at least a quarterly basis for changes in circumstances and any corresponding adjustments to the accrual are recorded in its statement of operations in the period when such changes are known.

Recent Accounting Pronouncements/Accounting Pronouncements Not Yet Effective
Recent Accounting Pronouncements
Accounting Pronouncements Recently Adopted
In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for convertible instruments by removing certain separation models in ASC 470-20, Debt—Debt with Conversion and Other Options, for convertible instruments. On December 26, 2021, the Company adopted ASU 2020-06 using the modified retrospective method. Applying the transition guidance, the Company was required to apply the guidance to all impacted financial instruments that were outstanding as of December 26, 2021 with the cumulative effect recognized as an adjustment to the opening balance of accumulated deficit.
The adoption of ASU 2020-06 required the Company to record a $196.5 million reduction of additional paid in capital, on December 26, 2021, due to the recombination of the equity conversion component of convertible debt remaining outstanding, which was initially separated and recorded in equity. The $122.0 million increase in debt represented the removal of the remaining debt discounts recorded for this previous separation. The Company recognized a $74.5 million cumulative effect decrease of initially applying ASU 2020-06 as an adjustment to the December 26, 2021 opening balance of accumulated deficit. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible senior notes as a liability instrument. Since the Company had a net loss in 2022, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share in 2022 as a result of adopting ASU 2020-06. The prior period consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods.
