**Part I**

**Special Note Regarding Forward-Looking Statements**

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements concerning our completed, pending, or proposed transactions, investments, product development, Private Connectivity Fabric<sup>SM</sup> ("PCF") buildouts, transformation plans, deleveraging plans, modernization and simplification initiatives, and other initiatives, including benefits or costs associated therewith;

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

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

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

------

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Affiliate Services**: We provide our affiliates certain communication services that we also provide to external customers. Please see our products and services listed above for further description of these services.

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

**Our Network** 

We deliver most of our products and services through our network, together with Lumen's, which is primarily built on fiber-optic cables and supporting equipment. Portions of our network use leased assets, and much of the equipment uses licensed software.

***Connectivity***

We created our communications network by constructing our own assets and through a combination of purchasing other companies and purchasing or leasing facilities from others. We designed our network to provide communications services that employ, and take advantage of, rapidly improving underlying optical, Internet Protocol, computing, and storage technologies.

As discussed in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Item 7 and Note 2 — Divestiture in Item 8, we sold portions of our network during 2023.

***Strategic Investments and Modernization***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• simplifying and modernizing our network and legacy systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• retiring aging and obsolete infrastructure and systems; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expanding our network to meet growing demand for enhanced and new products.

***Leased Network Assets***

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

***Cybersecurity and Network Resilience***

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

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

**Competition**

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

***Our Success***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhancing and integrating existing products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• introducing new offerings quickly and cost-effectively;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• meeting changing customer needs;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extending our core technologies into new applications; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• anticipating industry and technology shifts.

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

***Business***

We compete for business customers based on factors such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• network reliability and comprehensive coverage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• data transmission speed and latency;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pricing and billing simplicity;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• integrated service offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• IP network reach and peering capacity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• digital ordering capabilities and ease of use; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer service quality.

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

**Research, Development and Intellectual Property**

As of December 31, 2025, we held approximately 1,040 patents and patent applications in the U.S. and other countries. We have also received licenses to use patents held by others. We plan to continue to file new patent applications as we enhance and develop products and services, and we plan to continue to seek opportunities to expand our patent portfolio through strategic acquisitions and licensing.

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

For information on various litigation risks associated with owning and using intellectual property rights, see "Risk Factors — Business Risks" in Item 1A and Note 16 — Commitments, Contingencies and Other Items in Item 8.

**Regulation of Our Business**

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

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

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

**Federal Regulation of Domestic Operations**

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our access to and use of telephone numbers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our provision of emergency 911 services; and

------

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

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

***Other Federal Regulation***

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

***Broadband Regulation***

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

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

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• hinder our ability to operate our data networks efficiently;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrict necessary network management practices to ensure quality service; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase the cost of operating, maintaining, and upgrading our network.

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

**State Regulation of Domestic Operations**

State regulatory agencies have jurisdiction when our facilities and services are used to provide intrastate telecommunications services. Level 3 provides competitive services that are generally subject to less state regulation than incumbent local exchange carriers ("ILEC"s).

------

**Data Privacy Laws and Regulations** 

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

*<u>International Regulations</u>*

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

*<u>Domestic Regulations</u>*

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

**Anti-Bribery and Corruption Regulations**

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

**Regulation of International Operations**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exports and imports of various goods or technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain sanctioned business activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• competition; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cross-border data flows.

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

**Other Regulations**

Our networks and properties are subject to numerous federal, state, and local laws and regulations, including those governing the use, storage, and disposal of hazardous materials, the release of pollutants into the environment, and the remediation of contamination. Our contingent liabilities under these laws are further described in Note 16 — Commitments, Contingencies and Other Items in Item 8.

------

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

**Seasonality**

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

**ITEM 1A. RISK FACTORS**

**&nbsp;&nbsp;&nbsp;&nbsp;**

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

**Business Risks**

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

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

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

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

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

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

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

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

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

------

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide a more comprehensive portfolio of communications products and services;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• conduct operations or raise capital at lower costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• are subject to fewer regulatory constraints or costs;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain larger-scale operations.

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

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

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

To remain competitive, we must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• accurately predict and respond to technological developments;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• migrate customers from legacy offerings to newer products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provision our products and services quickly and reliably;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• retire outdated services cost-effectively.

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

------

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

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

***Declining revenues and financial uncertainty could adversely affect our business.***

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

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

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

The Lumen and Level 3 brand names, together with our corporate reputation, are critical assets that support our ability to attract and retain customers and employees. These assets are vulnerable to significant harm from events such as customer or competitor disputes, cyber-attacks, service outages, data breaches, internal control deficiencies, performance failures, compliance violations, employee misconduct, government investigations, or litigation. Similar incidents involving competitors could also generate negative publicity for the entire industry, indirectly impacting our business.

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

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

------

***We could be materially impacted by cyber-attacks.***

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our storage of digital information on Internet-connected servers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• use of open and software-defined networks;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rising demand for data services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increasing customer scale and complexity of service requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our large remote workforce;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our IT support obligations tied to divested businesses; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• escalating sophistication of threat actors.

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

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

------

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

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

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

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

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

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

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

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

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

------

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

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

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

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

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

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

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

***Adverse developments impacting our non-consolidated affiliates could indirectly impact us.***

Our consolidated operations constitute only a portion of the consolidated operations of our corporate parent, Lumen. We engage in various intercompany transactions with affiliates of Lumen that are not members of our consolidated group of companies. Events or developments that adversely impact these non-consolidated affiliates will not directly impact our consolidated financial position or performance as reported under GAAP, but could nonetheless indirectly adversely impact us to the extent such developments interfere with the ability of such non-consolidated affiliates to provide services or pay amounts to which we or our subsidiaries are entitled. For these reasons, you are urged to review the risk factor disclosures contained in Item 1A of Lumen's Annual Report on Form 10-K for the year ended December 31, 2025.

***We face other business risks.***

We face additional business risks, including:

------

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties and risks associated with acquiring or disposing of businesses or pursuing other strategic transactions.

**Legal and Regulatory Risks**

***Complex and evolving regulations could increase operational and compliance costs.***

As explained in greater detail elsewhere in this annual report, we are subject to numerous, often complex and occasionally conflicting laws and regulations at the international, federal, state, and local levels. While Level 3 provides competitive services that are generally not subject to state regulation to the same degree as ILECs, we cannot assure that we will successfully obtain or maintain all authorization licenses necessary to operate in our markets, and full compliance cannot be guaranteed at all times. Even when authorizations are secured, the service standards and conditions imposed under these authorizations and related laws may increase costs, restrict operational flexibility, or expose us to third-party claims.

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

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

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

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

Laws governing our operations have long been unsettled, limiting our ability to plan effectively. Regulatory uncertainty has increased following a 2024 U.S. Supreme Court decision eliminating judicial deference to agency interpretations of ambiguous federal laws. Future legislation or court rulings could impose burdensome requirements or liabilities. For example, our business could be materially impacted if U.S. Congress amends or repeals current federal limitations on the liability of private network providers, such as us, for third-party content stored or transmitted on private networks, as proposed by certain officials and consumer groups. We could also be significantly affected by initiatives to expand regulation of internet service providers or strengthen data privacy laws.

------

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

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

***Pending legal proceedings involving us and our affiliates could have a material adverse impact on us.***

We and our affiliates are involved in several potentially material proceedings, including derivative and class action lawsuits. The outcome of these matters is inherently uncertain, and we may incur losses that exceed our recorded liabilities or insurance coverage. Any of the proceedings described in Note 16 — Commitments, Contingencies and Other Items in Item 8, as well as other current or future litigation, could have a material adverse effect on our business, reputation, financial position, operating results, the market price of our debt securities, and our ability to access capital. We cannot provide assurance regarding the ultimate impact of these matters.

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

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

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

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

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

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

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

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

------

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

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

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

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

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

**Financial Risks**

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• requiring us to allocate a large portion of operating cash flow to interest and principal payments, reducing funds available for other purposes, including acquisitions, capital expenditures, strategic initiatives, and dividends to our ultimate parent company;

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negatively affecting perceptions of our company among customers, vendors, employees, and creditors;

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

------

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

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

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

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

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

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

Most of the debt of our subsidiary Level 3 Financing is secured by substantially all of its assets and guaranteed by certain affiliates. The remainder is unsecured but still guaranteed by certain affiliates, including us. Lumen Technologies, Inc. and certain of its subsidiaries owe significant amounts under various debt arrangements. Roughly three-quarters of Lumen Technologies, Inc.'s debt is guaranteed by principal domestic subsidiaries, some of which have pledged substantially all their assets — including the assets of their respective subsidiaries — to secure their guarantees. The rest is neither guaranteed nor secured. Substantial debt is also owed by certain subsidiaries of Qwest Communications International Inc. Most of the subsidiaries of Lumen Technologies, Inc. have neither borrowed funds nor guaranteed debt. As a result, determining the priority of rights among holders of our consolidated debt instruments is complex and depends on the assets and earnings of the issuing or guaranteeing entities. In addition, such debt is structurally subordinated to all liabilities of non-guarantor subsidiaries to the extent of the value of those subsidiaries that are obligors.

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

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

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

------

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evolving customer service requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the need to maintain aging or obsolete infrastructure until replacement;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory and contractual commitments.

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

***Our ability to meet our obligations depends on cash flows from our subsidiaries.***

Because we and Level 3 Financing are holding companies, substantially all of our income and operating cash flow is dependent upon the earnings of our respective subsidiaries and their distribution of those earnings to us in the form of dividends, loans or other payments. As a result, we rely upon our subsidiaries to generate cash flows in amounts sufficient to fund our obligations, including the payment of our long-term debt. Our respective subsidiaries are separate and distinct legal entities and, except where they have provided guarantees, have no obligation to pay amounts owed by us or to make funds available for our use. Subject to limited exceptions for tax or cash management purposes, non-guarantor subsidiaries are not required to provide us with cash through dividends, loans, or other transfers.

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

We periodically transfer cash to our controlling equity owner, Lumen Technologies, which creates certain risks. Lumen Technologies currently owes us under affiliate credit facilities, and any adverse developments affecting Lumen could impact our ability to collect this debt. While Level 3 Financing can freely transfer assets to us, we plan to continue distributing a substantial portion of our consolidated cash flow to our equity holder, reducing funds available for debt repayment or other purposes. Additional risks related to investing in our debt securities are detailed in the disclosure documents distributed at the time of issuance.

------

***We may not be able to fully utilize our NOLs.***

We have substantial federal and state net operating loss carryforwards ("NOL"s). Federal and state tax attributes, including NOLs, can be subject to limitations under Section 382 of the Internal Revenue Code and related regulations ("Section 382") and similar state tax laws. These limitations could restrict our ability to use these NOLs under our separate return method in the amounts we project. In an effort to safeguard these NOLs, Lumen has maintained an NOL rights agreement which is scheduled to lapse in late 2026. Our state NOLs are subject to legal and practical limitations on our ability to realize their full benefit. We cannot assure you we will be able to utilize our federal and state NOLs as projected or at all.

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

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

***We face other financial risks.***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• future intangible asset impairments could result in significant non-cash charges, reducing earnings and member's equity and adversely affecting our financial condition;

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

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

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

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

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

**Divestiture Risks**

***We may not realize the anticipated benefits of our completed divestiture.***

In connection with divesting our EMEA business in 2023, we completed internal restructurings and entered into multi-year agreements with the purchasers to provide certain transitional services and to provide or receive certain commercial services. It has been challenging and time-consuming to provide transition services, and we expect this will continue to be the case. Consequently, we may:

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

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

------

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sustain losses or inefficiencies from stranded or underutilized assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lose customers dissatisfied with post-closing services;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• experience operational challenges separating divested assets from retained assets.

Divestitures may not yield the expected benefits. We could incur greater tax or other costs, realize fewer benefits under the purchase agreement and related post-closing arrangements, or face operational challenges separating divested assets from retained assets. We may experience losses from stranded or underutilized assets, reduced future cash flows, and dis-synergies. We may not realize the expected proceeds, cash flows, or strategic benefits on the anticipated timeline or in the amounts projected. In addition, we remain subject to ongoing obligations and liabilities, including indemnification obligations, which could continue to divert resources and adversely affect our financial condition and results of operations. The 2023 divestiture has reduced our cash flows. If our remaining business underperforms, these effects could exacerbate other financial risks described elsewhere in this section, including our ability to meet cash requirements.

**General Risks**

***Changes in government trade policies could adversely affect our business.***

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

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

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

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

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

*Risk Management and Strategy* 

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

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

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

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

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

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

------

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

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

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

*Governance* 

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

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

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

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

------

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

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

**Current Business Environment and Macroeconomic Factors**

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Supply constraints**: Shortages of critical components and other materials have slowed certain network expansion efforts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Customer behavior**: Certain customers have delayed purchasing decisions, which has occasionally impacted sales cycles.

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

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

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

**Trends Impacting Our Operations**

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

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to refinance our debt obligations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• capital contributions, advances, or loans from Lumen or its affiliates.

Key balances as of December 31, 2025 included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash and cash equivalents**: $380 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Notes receivable-affiliate**: $2.7 billion

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Total consolidated indebtedness**: $9.8 billion

------

As of December 31, 2025, $28 million of our cash and cash equivalents were held in foreign bank accounts for funding our foreign operations. Due to various factors, our access to foreign cash is generally more restricted than our access to domestic cash.

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

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

**Cash Flow Activities**

The following table summarizes our consolidated cash flow activities:

---

| | | | |
|:---|:---|:---|:---|
| | **Years Ended December 31,** | **Years Ended December 31,** | **$ Change** |
| | **2025** | **2024** | **$ Change** |
| | **(Dollars in millions)** | **(Dollars in millions)** | **(Dollars in millions)** |
| Net cash provided by operating activities | $4066 | 3131 | 935 |
| Net cash used in investing activities | (2285) | (2204) | 81 |
| Net cash used in financing activities | (2001) | (2345) | (344) |

---

***Operating Activities***

Net cash provided by operating activities increased $935 million in 2025 compared to 2024. This was primarily as a result of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an increase in deferred revenue related to receipt of advance cash payments pursuant to recent sales of PCF solutions.

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

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

***Investing Activities***

Net cash used in investing activities increased $81 million in 2025 compared to 2024. This was primarily as a result of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an increase in capital expenditures; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an offsetting decrease due to the issuance of notes receivable - affiliate to our ultimate parent company in 2024 under the credit facilities described elsewhere herein, with no like transaction in 2025.

***Financing Activities***

Net cash used in financing activities decreased $344 million in 2025 compared to 2024. This was primarily as a result of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an increase in net proceeds from issuances of debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a decrease in distributions to affiliates; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an offsetting increase in payments of long-term debt.

See Note 7 — Long-Term Debt and Credit Facilities for details on our debt transactions.

**Short-term Liquidity Needs**

As of December 31, 2025, we held cash and cash equivalents of $380 million and outstanding Notes receivable - affiliate of $2.7 billion. A significant component of our liquidity is dependent upon Lumen's ability to repay its obligation to us. See Note 15 — Affiliate Transactions for details on terms and conditions of the credit facilities we extended to Lumen Technologies. These resources, together with cash generated from operating activities, represent our primary sources of liquidity for the next 12 months.

Based on our current capital allocation objectives, we project expenditures for the next 12 months to include, among others, capital expenditures, primarily for network modernization and fiber expansion, and lease payments for our operating and finance lease obligations.

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

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

**Long-term Liquidity Needs**

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

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

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

**Impact of Strategic Transactions on Liquidity**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Recent divestiture**: The 2023 sale of our EMEA business generated significant cash proceeds but reduced recurring operating cash flows.

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

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

------

**Capital Expenditures**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expanding our fiber network;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modernizing and enhancing network efficiency and reliability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developing new services; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• replacing aging network assets.

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

For additional details on our capital spending, see "Cash Flow Activities — *Investing Activities*" above, "Business" in Item 1, and "Risk Factors" in Item 1A.

**Debt Instruments and Financing Arrangements** 

***Debt Instruments***

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

Key debt balances as of December 31, 2025 included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Secured debt outstanding**: $7.5 billion

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Unsecured debt outstanding**: $2.1 billion

For additional details on our debt and financing instruments and the debt activity below, see Note 7 — Long-Term Debt and Credit Facilities in Item 8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash Redemptions — First Quarter**: Level 3 Financing Inc. redeemed $70 million of unsecured Senior notes in exchange for cash.

For more details on the 2025 debt activity, see Note 7 — Long-Term Debt and Credit Facilities in Item 8.

*<u>2026 Debt Activity</u>*

Key transactions in early 2026 included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Senior Secured Notes**: Level 3 Financing Inc. issued an additional $650 million of its 8.500% Senior Notes due 2036. Net proceeds from this offering were used to fund the purchase of $607 million of its Second Lien notes, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ $4 million 3.875% Second Lien Notes due 2030.

***Future Debt Transactions***

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

------

As of the filing date of this report, credit ratings for the senior secured and unsecured debt of Level 3 Financing were:

---

| | | | |
|:---|:---|:---|:---|
| **Borrower** | **Moody's Investors Service, Inc.** | **Standard & Poor's** | **Fitch Ratings**<sup>(1)</sup> |
| **Level 3 Financing, Inc.** | | | |
| &nbsp;&nbsp;&nbsp;Unsecured | B3 | B- | B- |
| &nbsp;&nbsp;&nbsp;Secured | Ba3 | B+ | BB |

---

_______________________________________________________________________________

<sup>(1)</sup> In February 2026, Moody's and Fitch upgraded our secured and unsecured notes ratings.

Future changes in these ratings, or Lumen's ratings, could impact our access to capital and borrowing costs. We cannot be certain that we will be able to borrow additional funds on favorable terms, or at all. See "Risk Factors — Financial Risks" in Item 1A.

***Letters of Credit***

It is customary for us to use various financial instruments in the normal course of business. These instruments include letters of credit which are conditional commitments issued on our behalf in accordance with specified terms and conditions. As of December 31, 2025, we had outstanding letters of credit or other similar obligations of approximately $2 million, all of which were collateralized by restricted cash.

**Future Contractual Obligations**

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

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Footnote Reference** | **Current** <br>**Obligation**<br>*(within next 12 months)* | **Long-term** <br>**Obligation**<br>*(beyond next 12 months)* | **Total** |
| | | **(Dollars in millions)** | **(Dollars in millions)** | **(Dollars in millions)** |
| Long-term debt (excluding unamortized premiums, net and unamortized debt issuance costs) | Note 7 — Long-Term Debt and Credit Facilities | $36 | 9789 | 9825 |
| Operating leases | Note 5 — Leases | 303 | 969 | 1272 |
| Right-of-way agreements and purchase commitments | Note 16 — Commitments, Contingencies and Other Items | 194 | 644 | 838 |
| Asset retirement obligations | Note 9 — Property, Plant and Equipment | 16 | 79 | 95 |
| Total |  | $549 | 11481 | 12030 |

---

**Distributions and Contributions**

From time to time, we make distributions to and receive contributions from our ultimate parent company, which decrease or increase our capital resources available for debt repayments and other purposes. For additional details, see our consolidated statements of member's (deficit) equity and consolidated statements of cash flows.

------

**Other Matters**

***Legal Proceedings and Other Contingent Liabilities***

We are subject to various legal proceedings and other contingent liabilities that individually or in the aggregate could materially affect our financial condition, future results of operations, or cash flows. See Note 16 — Commitments, Contingencies and Other Items for additional information.

Lumen Technologies is involved in several legal proceedings to which we are not a party that, if resolved against it, could have a material adverse effect on its business and financial condition. As a wholly owned subsidiary of Lumen Technologies, our business and financial condition could be similarly affected. You can find descriptions of these legal proceedings in Lumen's quarterly and annual reports filed with the SEC. Because we are not a party to any of the matters, we have not accrued any liabilities for these matters as of December 31, 2025.

***Federal Broadband Support Programs***

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

***Tax Law Changes***

In July 2025, the U.S. enacted H.R. 1, also known as the "One, Big Beautiful Bill Act" (the "OBBBA"), which permanently allows 100% bonus depreciation, immediate expensing for domestic R&D, and favorable changes to interest expense limitations. These provisions did not have a material impact on our 2025 effective tax rate but are expected to significantly reduce the utilization of our federal NOLs.

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

**CRITICAL ACCOUNTING ESTIMATES**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• intangible assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loss contingencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• affiliate transactions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• income taxes.

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

------

**Intangible Assets**

We have a significant amount of finite-lived intangible assets that are subject to annual reviews of their estimated lives and amortization methods. As of December 31, 2025, our finite-lived intangible assets totaled $2.9 billion, or 17% of our total assets. The impairment analyses of these assets are considered critical because of their significance to us, the subjective nature of certain assumptions used to estimate fair value, and because it can materially impact reported results and future expense.

***Amortization***

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

We amortize finite-lived intangible assets using the straight-line method over the following estimated lives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Customer relationships**: 7 - 14 years

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Capitalized software**: 3 - 7 years

The amount of future amortization expense may differ materially from current amounts, depending on the results of our annual reviews. For additional information on our intangible assets, see Note 3 — Intangible Assets.

**Loss Contingencies**

We are involved in several potentially material legal proceedings, as described in Note 16 — Commitments, Contingencies and Other Items in Item 8. Accounting for these matters requires significant judgment due to inherent uncertainty, complex legal interpretations, and evolving circumstances. We recognize an expense when a loss is probable and reasonably estimable. Determining whether a loss is probable and reasonably estimable involves significant judgment and assumptions about future events. These assumptions include legal interpretations, regulatory developments, and estimates of potential exposure. Actual outcomes may differ from these estimates, and such differences could materially affect our consolidated financial statements. Changes in assumptions or new developments could significantly increase or decrease earnings.

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

**Affiliate Transactions** 

&nbsp;&nbsp;&nbsp;&nbsp;

We provide to and receive from Lumen Technologies and its subsidiaries ("our affiliates") various communications and other services. We recognize intercompany charges for the amounts billed to us by our affiliates and we recognize intercompany revenue for services we bill to our affiliates.

Because of the significance of the services we provide to our affiliates and our other affiliate transactions, and the services our affiliates provide to us, the results of operations, financial position and cash flows presented herein are not necessarily indicative of the results of operations, financial position and cash flows we would have achieved had we operated as a stand-alone entity during the periods presented. Regarding telecommunications services that we received from our affiliates, we saw a reduction to affiliate expense for the year ended December 31, 2025. This is primarily due to the repricing of certain services provided to us to align with lower market rates including certain transport services, along with the termination of certain affiliate circuits that we no longer need to provide services to our external customers. See Note 15 — Affiliate Transactions for additional information.

Affiliate transactions are considered a critical accounting estimate because they involve significant judgment in determining pricing, allocation of costs, and the nature of services exchanged, all of which can materially impact reported results.

------

**Income Taxes**

We are included in the consolidated federal income tax return of Lumen Technologies. Lumen Technologies treats our consolidated results as if we were a separate taxpayer. We are required to pay our tax liabilities to Lumen Technologies based upon our separate return taxable income. We are also included in the combined state tax returns filed by Lumen Technologies.

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

***Uncertain Tax Positions***

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

***Deferred Taxes***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax credit carryforwards;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NOLs and other tax attribute carryforwards.

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

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

------

***Valuation Allowances***

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

As of December 31, 2025, we had a valuation allowance of $107 million, primarily related to state NOLs expected to expire unused. Future changes in earnings forecasts or the nature and estimated timing of future deductions and benefits may require adjustments to valuation allowances, which could materially impact our financial condition or results of operations.

We evaluate tax matters on a quarterly basis; see Note 13 — Income Taxes in Item 8 for additional details.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

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

**Interest Rate Risk**

As of December 31, 2025, we had approximately $2.4 billion aggregate principal amount of debt bearing unhedged floating interest rates based on the secured overnight financing rate ("SOFR"). A hypothetical increase of 100 basis points in SOFR relating to our unhedged floating rate debt would, among other things, decrease our annual pre-tax earnings by approximately $24 million.

**ITEM 8. CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA**

**Report of Independent Registered Public Accounting Firm**

To the Board of Directors and Member

Level 3 Parent, LLC:

*Opinion on the Consolidated Financial Statements*

We have audited the accompanying consolidated balance sheets of Level 3 Parent, LLC and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive loss, cash flows, and member's (deficit) equity for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

*Basis for Opinion*

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

*Critical Audit Matters*

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

*Testing of revenue*

As discussed in Note 4 to the consolidated financial statements, the Company recorded $6.5 billion of operating revenues for the year ended December 31, 2025. The processing and recording of revenue are reliant upon multiple information technology (IT) systems.

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

------

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

*Sufficiency of audit evidence over the implementation of enterprise resource planning system* 

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

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

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over the ERP implementation. We involved IT professionals with specialized skills and knowledge, who assisted in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• obtaining an understanding of the relevant IT applications

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluating the design and testing the operating effectiveness of certain general IT controls, including controls related to program development, change management, and logical access

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluating the design and testing the operating effectiveness of certain IT application controls, including inspecting and evaluating configurations and interfaces.

We evaluated the sufficiency of audit evidence obtained by assessing the results of procedures performed, including the appropriateness of the nature and extent of the audit effort.

We have served as the Company's auditor since 2002.

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

**General**

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

**Basis of Presentation**

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (Lumen Technologies and its other subsidiaries, referred to herein as affiliates) have not been eliminated.

We reclassified certain prior period amounts to conform to the current period presentation, including our revenue by product and service categories for 2024 and 2023. See Note 4 — Revenue Recognition for additional information. These changes had no impact on total operating revenue, total operating expenses, or net loss for any period.

**Segments**

Our operations are integrated into and reported as part of Lumen Technologies' operations. Lumen's Chief Executive Officer serves as our chief operating decision maker ("CODM") and reviews our financial information on an aggregate basis in connection with our quarterly and annual SEC filings. Our CODM evaluates performance and allocates resources in conjunction with and based on the operations of Lumen Technologies. Accordingly, we do not provide our discrete financial information to the CODM on a regular basis and have determined that we have one reportable segment.

**Operating Expenses**

Our current definitions of operating expenses are as follows:

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rents and utilities expenses;

------

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other expenses directly related to our operations.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• marketing and advertising;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• property and other operating taxes and fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• external commissions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• legal expenses associated with general matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• bad debt expense; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other selling, general, and administrative expenses.

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

**Summary of Significant Accounting Policies**

***Use of Estimates***

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

We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 13 — Income Taxes and Note 16 — Commitments, Contingencies and Other Items for additional information.

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

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

For all of these and other matters, actual results could differ materially from our estimates.

------

***Revenue Recognition***

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identification of the contract with a customer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identification of the performance obligations in the contract;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• determination of the transaction price;

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

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

*<u>Service and Equipment Revenue</u>*

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

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

*<u>Performance Obligations</u>*

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

*<u>Deferred Revenue and Fees</u>*

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

*<u>Billing Practices</u>*

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

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

------

*<u>Contract Costs</u>*

We defer (or capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 36 months. These deferred costs are periodically monitored to reflect any significant change in assumptions.

*<u>Contract Modifications</u>*

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

*<u>Indefeasible Rights of Use and Leases</u>*

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

*<u>Service Level Commitments</u>*

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

***Affiliate Transactions***

We provide services to our affiliates that we also provide to external customers. Revenue from these services is recognized as Operating revenue – affiliates in our consolidated statements of operations. Similarly, services provided to us from our affiliates are recognized as Operating expenses – affiliates in our consolidated statements of operations. Due to the significance of these intercompany transactions, our results of operations, financial position, and cash flows may not be indicative of what they would have been had we operated as a stand-alone entity during the periods presented.

Intercompany charges are recognized at the amounts billed to us by our affiliates, and intercompany revenue is recognized for services we bill to our affiliates. The resulting net balances from these transactions are reported as Accounts receivable – affiliates or Accounts payable – affiliates in our consolidated balance sheets.

From time to time, to the extent permitted by our debt covenants, we make distributions to and receive contributions from our parent, which increase or decrease our capital resources for debt repayment or other purposes. These transactions are reflected in our consolidated statements of member's (deficit) equity, and related cash flows are presented as distributions and contributions within financing activities in our consolidated statements of cash flows. Non-cash distributions are disclosed in the supplemental non-cash financing information in our consolidated statements of cash flows.

Our ultimate parent company, Lumen Technologies, is currently indebted to us under a revolving credit facility.

For additional information, see Note 15 — Affiliate Transactions.

***Legal Costs***

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

------

***Income Taxes***

Lumen Technologies treats our consolidated results as if we were a separate taxpayer. Our reported deferred tax assets and liabilities, as discussed below and in Note 13 — Income Taxes, are primarily determined as a result of the application of the separate return method and therefore the settlement of these amounts is dependent upon our parent, Lumen Technologies, rather than tax authorities. We are required to pay our tax liabilities based upon our separate return taxable income. We are also included in the combined state tax returns filed by Lumen Technologies. The provision for income taxes reflects taxes currently payable, tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to tax attributes carryforwards, including NOL carryforwards and tax credit carryforwards and differences between the financial statement carrying value of assets and liabilities and the tax basis of those assets and liabilities. Deferred taxes are computed using enacted tax rates expected to apply in the year in which the differences are expected to affect taxable income. The effect on deferred income tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date.

We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain or adjust each valuation allowance on our deferred tax assets. See Note 13 — Income Taxes for additional information.

***Cash and Cash Equivalents***

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

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

***Restricted Cash***

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

***Accounts Receivable and Allowance for Credit Losses***

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

We generally consider our accounts past due if they are outstanding over 30 days. Our past due accounts are written off against our allowance for credit losses and any recoveries are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable net of the allowance for credit losses approximates fair value.

------

***Concentration of Credit Risk***

We provide communications services to a wide range of wholesale and enterprise customers, ranging from well capitalized global enterprises to small early stage companies primarily in the United States. Credit risk with respect to accounts receivable is generally diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographical regions. We perform ongoing credit evaluations of our customers' financial condition and generally require no collateral from our customers, although letters of credit and deposits are required in certain limited circumstances. We have, from time to time, entered into agreements with value added resellers and other channel partners to reach enterprise markets for voice services. We have policies and procedures in place to evaluate the financial condition of these resellers prior to initiating service to the final customer. We are not able to predict changes in the financial stability of our customers. Any material changes in the financial status of any one or a particular group of customers may cause us to adjust our estimate of the recoverability of receivables and could have a material effect on our results of operation.

***Assets Held for Sale***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• management commits to a plan to sell the assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the assets are available for immediate sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an active program to locate a buyer is initiated; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the sale is probable within one year.

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

Unless otherwise specified, the amounts and information presented in the notes do not include assets and liabilities that were classified as held for sale. See Note 2 — Divestiture and Note 9 — Property, Plant and Equipment for additional information.

***Property, Plant and Equipment***

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

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

*<u>Leasehold Improvements and Capital Projects</u>*

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

------

*<u>Useful Lives</u>*

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

*<u>Impairment Testing</u>*

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

*<u>Asset Retirement Obligations</u>*

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

***Goodwill and Intangible Assets***

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

We are required to reassign goodwill to reporting units whenever reorganizations of our internal reporting structure change the composition of our reporting units. Goodwill is reassigned to the reporting units using a relative fair value approach. When the fair value of a reporting unit is available, we allocate goodwill based on the relative fair value of the reporting units. When fair value is not available, we utilize an alternative allocation methodology that we believe represents a reasonable approximation of the fair value of the operations being reorganized.

*<u>Amortization</u>*

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Customer relationships**: 7 - 14 years, depending on customer type

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Capitalized software**: 3 - 7 years

------

*<u>Internal Use Software</u>*

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

*<u>Impairment Testing</u>*

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

Our goodwill was derived from Lumen's 2017 acquisition of us where the purchase price exceeded the fair value of the net assets acquired. Prior to becoming fully impaired in the second quarter of 2023, we tested goodwill for impairment annually as of October 31, or more frequently if events suggested a reporting unit's fair value may fall below its carrying value. If the carrying value of a reporting unit exceeds its fair value of equity, we write-down goodwill. The impairment assessment was performed at the reporting unit level. We have determined that our operations consist of one reporting unit, consistent with our determination that our business consists of one operating segment. We were required to write-down the value of goodwill in periods in which the carrying amount of our reporting unit's equity exceeded the estimated fair value of the equity of the reporting unit, limited to the goodwill balance.

*Second Quarter 2023 Goodwill Impairment Analysis*

During the second quarter of 2023, the Company determined circumstances existed indicating it was more likely than not that the carrying value of our reporting unit exceeded its fair value. Given the continued erosion in Lumen's market capitalization, we determined our quantitative impairment analysis would estimate the fair value of our reporting unit using only the market approach. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry which supported a range of fair values derived from annualized revenue and earnings before interest, tax, depreciation and amortization ("EBITDA") multiples between 1.5x and 4.3x and 4.6x and 10.5x, respectively. The revenue and EBITDA multiples were below these comparable market multiples. For the three months ended June 30, 2023, based on our assessment performed as described above, we concluded the estimated fair value was less than our carrying value of equity. As a result, our goodwill became fully impaired and we recorded a non-cash, non-tax-deductible goodwill impairment charge of $2.0 billion for the three months ended June 30, 2023.

The market approach that we used in the quarter ended June 30, 2023 test incorporated estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain strategic initiatives. In developing the market multiples, we considered observed trends of our industry participants. Our assessment included many factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairments. Subsequent to this impairment and as of December 31, 2025, we held no remaining goodwill.

For more information on our intangible assets, see Note 3 — Intangible Assets.

***Foreign Currency***

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

------

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

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

***Segments***

On January 1, 2024 we adopted Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The ASU does not change how a public entity identifies its operating segments, aggregates them or applies quantitative thresholds to determine reportable segments. Public entities with a single reportable segment are required to provide the new disclosures and all the disclosures required under ASC 280, "Segment Reporting." The adoption of this ASU did not have a material impact on our consolidated financial statements.

The adoption of this ASU did not have any impact on our consolidated financial statements.

On January 1, 2024, we adopted ASU 2022-03, "Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." This ASU clarifies that a contractual restriction on the sales of an investment in an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring its fair value. The adoption of this ASU did not have any impact on our consolidated financial statements.

***Leases***

On January 1, 2024, we adopted ASU 2023-01, "Leases (Topic 842): Common Control Arrangements." This ASU requires all entities to amortize leasehold improvements associated with common control leases over the useful life to the common control group. The adoption of this ASU did not have any impact on our consolidated financial statements.

***Income Taxes***

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures."

The adoption of this ASU did not have a material impact on our consolidated financial statements.

***Credit Losses***

On January 1, 2023, we adopted ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings ("TDR") and Vintage Disclosures." The ASU eliminates the TDR recognition and measurement guidance, enhances existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. The adoption of this ASU did not have a material impact on our consolidated financial statements.

------

In November 2025, the FASB issued ASU 2025-08, "Financial Instruments — Credit Losses (Topic 326): Purchased Loans." This ASU requires that loans acquired without credit deterioration and deemed "seasoned" will be considered purchased seasoned loans and accounted for using the gross-up approach at acquisition (i.e., record the loan at its purchase price and separately record an allowance for expected credit losses). Seasoned loans include all loans acquired in a business combination, that do not have "more-than-insignificant" deterioration of credit quality since origination, as well as loans purchased at least 90 days after origination, where the purchaser was not involved in the origination of the loans. The amendments in ASU 2025-08 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early adoption permitted. This ASU should be applied prospectively to loans that are acquired on or after the initial application date. The Company intends to early adopt ASU 2025-08 prospectively, effective January 1, 2026.

**Note 2 — Divestiture**

**EMEA Business**

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

The classification of the EMEA business as held for sale was considered an event or change in circumstance which required an assessment of the goodwill of the disposal group for impairment each reporting period until disposal. We performed a pre-classification and post-classification goodwill impairment test of the disposal group as described further in Note 3 — Intangible Assets. As a result of our impairment tests, we determined the EMEA business disposal group was impaired resulting in a non-cash, non-tax-deductible goodwill impairment charge of $224 million in the fourth quarter of 2022. As a result of our evaluation of the recoverability of the carrying value of the assets and liabilities held for sale relative to the agreed upon sales price, adjusted for costs to sell, we recorded an estimated loss on disposal of $616 million during the year ended December 31, 2022 in the consolidated statement of operations and a valuation allowance included in assets held for sale on the consolidated balance sheet as of December 31, 2022. For the year ended December 31, 2023, we recorded a $104 million net loss on disposal associated with the sale of our EMEA business. This loss is reflected as operating expense within the consolidated statements of operations.

------

The EMEA business was included in our continuing operations and classified as assets and liabilities held for sale on our consolidated balance sheets through the closing of the transaction on November 1, 2023. As a result of closing the transaction, we derecognized $1.4 billion of net assets, the principal components of which were as follows:

---

| | |
|:---|:---|

______________________________________________________________________

<sup>(1)</sup> <sup>&nbsp;&nbsp;&nbsp;&nbsp;</sup>Includes the impact of $350 million realized loss on foreign currency translation, net of tax, reclassified out of accumulated other comprehensive loss as of December 31, 2023 to the valuation allowance and loss on sale of the EMEA business.

We do not believe this divestiture transaction represents a strategic shift for us. Therefore, the divested business discussed above did not meet the criteria to be classified as discontinued operations. As a result, we continued to report our operating results for the EMEA business in our consolidated operating results through its respective disposal date November 1, 2023.

**Note 3 — Intangible Assets**

Intangible assets consisted of the following:

---

.

As of December 31, 2025 and 2024, the gross carrying amount of customer relationships and capitalized software was $8.4 billion and $8.5 billion, respectively, and the weighted average remaining useful lives of our finite-lived intangible assets were approximately:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Customer relationships: 5 years;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capitalized software: 4 years; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total intangible assets: 5 years.

***Amortization Expense***

Total amortization expense for finite-lived intangible assets for the years ended December 31, 2025, 2024 and 2023 was $683 million, $729 million and $714 million, respectively.

We estimate that future total amortization expense for finite-lived intangible assets will be as follows:

---

| | |
|:---|:---|
| | **(Dollars in millions)** |
| 2026 | $645 |
| 2027 | 603 |
| 2028 | 562 |

_______________________________________________________________

<sup>(1) &nbsp;&nbsp;&nbsp;&nbsp;</sup>Includes lease revenue which is not within the scope of ASC 606.

We do not have any single external customer that comprises more than 10% of our total consolidated operating revenue, and substantially all of our consolidated revenue comes from customers located in the United States.

**Customer Receivables and Contract Balances**

The following table provides balances of customer receivables, contract assets and contract liabilities, net of amounts classified as held for sale:

---

| | | |
|:---|:---|:---|
| | **December 31,** | **December 31,** |
| | **2025** | **2024** |
| | **(Dollars in millions)** | **(Dollars in millions)** |
| Customer receivables, less allowance of $16 and $12 | $764 | 529 |
| Contract assets | 13 | 12 |
| Contract liabilities | 259 | 267 |

---

Contract liabilities are consideration we have received from our customers or billed in advance of providing the goods or services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation and maintenance charges that are deferred and recognized over the actual or expected contract term, which typically ranges from one to five years depending on the service. Contract liabilities are included within Deferred revenue in our consolidated balance sheets. During the years ended December 31, 2025 and 2024, we recognized $150 million and $120 million, respectively, of revenue that was included in contract liabilities of $267 million and $222 million as of January 1, 2025 and 2024, respectively, including contract liabilities that were classified as held for sale.

**Performance Obligations**

As of December 31, 2025, we expect to recognize approximately $4.2 billion of revenue in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied. As of December 31, 2025, the transaction price related to unsatisfied performance obligation that are expected to be recognized in 2026, 2027, and thereafter was $2.1 billion, $1.2 billion, and $950 million, respectively.

------

These amounts exclude:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contracts that are classified as leasing arrangements that are not subject to ASC 606.

**Contract Costs**

The following tables provide changes in our contract acquisition costs and fulfillment costs:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Year Ended December 31, 2025** | **Year Ended December 31, 2025** | **Year Ended December 31, 2024** | **Year Ended December 31, 2024** |
| | **Acquisition Costs** | **Fulfillment Costs** | **Acquisition Costs** | **Fulfillment Costs** |
| | **(Dollars in millions)** | **(Dollars in millions)** | **(Dollars in millions)** | **(Dollars in millions)** |
| Beginning of period balance | $77 | 127 | 70 | 97 |
| Costs incurred | 49 | 119 | 55 | 103 |
| Amortization | (50) | (90) | (48) | (73) |
| End of period balance | $76 | 156 | 77 | 127 |

---

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

We amortize deferred acquisition and fulfillment costs based on the transfer of services on a straight-line basis over the average expected contract life of approximately 36 months for our business customers. We include amortized fulfillment costs in Cost of services and products and amortized acquisition costs in Selling, general and administrative expenses in our consolidated statements of operations. We include the amount of these deferred costs that are anticipated to be amortized in the next 12 months in Other current assets, net and the deferred costs expected to be amortized beyond 12 months is included in Other assets, net on our consolidated balance sheets. We assess deferred acquisition and fulfillment costs for impairment on a quarterly basis.

**Note 5 — Leases**

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

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

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

------

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

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

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

For the years ended December 31, 2025, 2024 and 2023 our gross operating lease revenue was $852 million, $694 million, and $676 million, respectively, which represents 13%, 11%, and 10%, of our operating revenue for the years ended December 31, 2025, 2024, and 2023.

Included in our operating lease revenue is sublease revenue of $11 million, $13 million and $14 million for the years ended December 31, 2025, 2024, and 2023, respectively.

**Note 6 — Credit Losses on Financial Instruments**

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

------

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

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

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

The following table presents the activity of our allowance for credit losses for our accounts receivable portfolio:

**2025 Debt Transactions**

During 2025, we completed various debt refinancing, term loan repricing, and further debt reduction transactions described below, which resulted in a $739 million net loss on early retirement of debt, recognized in Total other expense, net in our consolidated statement of operations for the year ended December 31, 2025. Additionally, these transactions resulted in early call premiums which were funded by proceeds from our debt issuances and are reflected as Debt issuance and extinguishment costs and related fees within our financing activities in our consolidated statements of cash flow.

***Second Lien Notes Refinancing*** — ***Fourth Quarter 2025***

On December 23, 2025, Level 3 Financing issued $1.25 billion of 8.500% Senior Notes due 2036. On such date, Level 3 Financing used the net proceeds from the offering, together with cash on hand for the 2025 Early Settlement Cash Tender Offers (as defined herein) noted below.

***Cash Tender Offers*** — ***Fourth Quarter 2025***

Pursuant to cash tender offers that commenced on December 8, 2025 (the "2025 Early Settlement Cash Tender Offers"), in December 2025 we reduced the aggregate principal amount of our consolidated indebtedness by $1.6 billion as described in the table below.

This amendment revised the Original Level 3 Credit Agreement to, among other things, (i) reduce the pricing on Level 3 Financing's term loan facility and make related changes to effect such repricing and (ii) extend the maturity of Level 3 Financing's term loan facility to 2032. Immediately following the First Credit Facilities Transactions, Level 3 Financing had $2.4 billion of outstanding borrowings under its new secured Term Loan B-3 facility.

The Company determined that the First Credit Facilities Transactions constituted a debt extinguishment and recorded a loss of $34 million, which is included in our aggregate Net (loss) gain on early retirement of debt in Total other expense, net in our consolidated statement of operations for the year ended December 31, 2025.

In conjunction with the Cash Tender Offers, we recorded a gain of $31 million including an offset of immaterial third-party fees in our aggregate Net (loss) gain on early retirement of debt in Other income, net in our consolidated statement of operations for the year ended December 31, 2024.

These transactions reduced the aggregate principal amount of Level 3 Financing's consolidated indebtedness by $7 million.

| Total | Total | $7548 |

______________________________________________________________________

N/A - Not applicable

In evaluating the terms of the TSA Transactions, we determined that for certain of our creditors the new debt instruments were substantially different than pre-existing debt and therefore constituted a non-cash extinguishment of old debt of $2.6 billion and the establishment of new debt for which we recorded a gain on extinguishment in the first quarter of 2024. This new debt was recorded at fair value generating a reduction to debt of $261 million which resulted in a net gain of $54 million, and is included in our aggregate Net (loss) gain on early retirement of debt in Other income, net in our consolidated statement of operations for the year ended December 31, 2024. The remaining creditors' debt was not substantially different under the terms of the TSA Transactions and was treated under modification accounting rules. In conjunction with the TSA Transactions, we paid $209 million in lender fees and $112 million in additional third-party costs. Of these amounts, we offset $157 million of lender fees against the gain on extinguishment and recorded $61 million in third-party costs to Selling, general and administrative expense in our consolidated statement of operations for the year ended December 31, 2024. In accordance with GAAP provisions for modification and extinguishment accounting, $52 million in lender fees and $51 million in third-party costs, respectively, were capitalized and will be amortized over the terms of the newly-issued indebtedness.

***Repurchases of Debt Instruments***

During 2024, Level 3 Financing repurchased various debt instruments on the open market. These repurchases resulted in an aggregate net gain of $34 million which is included in our aggregate Net (loss) gain on early retirement of debt in Other income, net in our consolidated statement of operations for the year ended December 31, 2024. The following table sets forth the aggregate principal amount of each series of notes repurchased during the year ended December 31, 2024:

**2023 Debt Transactions**

***Exchange Offers***

Pursuant to exchange offers that commenced on March 16, 2023 (the "2023 Exchange Offers"), on March 31, 2023, Level 3 Financing issued $915 million of its 10.500% Senior Secured Notes due 2030 (the "10.500% Notes") in exchange for $1.535 billion of Lumen's outstanding senior unsecured notes.

On April 17, 2023, in connection with the 2023 Exchange Offers, Level 3 Financing issued an additional $9 million of its 10.500% Notes in exchange for $19 million of Lumen's outstanding senior unsecured notes.

**Level 3 Financing Credit Agreements**

***Credit Agreement dated March 22, 2024***

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

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

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

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

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

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

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

***Former Facility Tranche B Term Loan***

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

------

**Level 3 Guarantees of Lumen Credit Agreements**

Lumen's obligations under its Superpriority Revolving/Term A Credit Agreement dated as of March 22, 2024 (the "RCF/TLA Credit Agreement") are unsecured, but Level 3 Parent, Level 3 Financing, and certain of Level 3 Financing's subsidiaries (collectively, the "Level 3 Collateral Guarantors") have provided an unconditional guarantee of payment of up to $150 million of Lumen's obligations under both of the revolving credit facilities created under the RCF/TLA Credit Agreement. Certain of such guarantees will be secured by a lien on substantially all of the assets of the applicable Level 3 Collateral Guarantors. The guarantee by the Level 3 Collateral Guarantors may be reduced or terminated under certain circumstances.

**Senior Notes**

The Company's consolidated indebtedness as of December 31, 2025 included (i) First and Second Lien secured notes issued by Level 3 Financing and (ii) Senior unsecured notes issued by Level 3 Financing. All of these notes carry fixed interest rates and all principal is due on the notes' respective maturity dates, which rates and maturity dates are summarized in the table above. Level 3 Financing generally can redeem the notes, at its option, in whole or in part, (i) pursuant to a fixed schedule of pre-established redemption prices, (ii) pursuant to a "make whole" redemption price or (iii) under certain other specified limited conditions.

**Revolving Letters of Credit**

We use various financial instruments in the normal course of business. These instruments include letters of credit, which are conditional commitments issued on our behalf in accordance with specified terms and conditions. As of December 31, 2025 and 2024, we had outstanding letters of credit or other similar obligations of approximately $2 million, all of which were collateralized by restricted cash in each year. None of our conditional commitments under our outstanding letters of credit are reflected as debt on our consolidated balance sheets.

**Certain Guarantees and Security Interests**

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

Level 3 Financing's obligations under its first lien notes are secured by a first priority lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals), and are guaranteed by the other Level 3 Collateral Guarantors (or, for certain such guarantors, for certain notes will be guaranteed upon the receipt of required regulatory approvals) on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement. Level 3 Financing's obligations under its second lien notes are secured by a second lien on substantially all of its assets, and are guaranteed by the other Level 3 Collateral Guarantors on the same basis as the guarantees provided by such entities under the Level 3 Credit Agreement, except the lien securing such guarantees is a second lien.

Level 3 Financing's obligations under its unsecured notes are guaranteed on an unsecured basis by the same affiliated entities that guarantee the Level 3 Credit Agreement and secured notes.

**Supplier Finance Program**

Pursuant to our purchase of network equipment under a supplier finance program implemented in 2021 with one of our key equipment vendors, we are obligated to make quarterly installment payments over a five-year period and pay annual interest of 1.25% on unpaid balances. The first unsecured quarterly payment was due April 27, 2022, with remaining quarterly payments due through the end of the term on July 1, 2026.

The supplier also agreed to certain milestone performance and other provisions that could result in us earning credits to be applied by us towards future equipment purchases. As of December 31, 2025 and 2024, we have earned and received, or have the potential to receive, $28 million and $24 million, respectively, of credits.

| | **2025** | **2024** |
| | **(Dollars in millions)** | **(Dollars in millions)** |
| Balance at beginning of period | $39 | 55 |
| &nbsp;&nbsp;Liabilities settled | (21) | (16) |
| Balance at end of period | $18 | 39 |

---

As of December 31, 2025 and 2024, $18 million and $21 million were included in Current maturities of long-term debt, and as of December 31, 2024, $18 million was included in Long-term debt.

**Interest Expense**

Interest expense includes interest on total long-term debt. The following table presents the amount of gross interest expense, net of capitalized interest:

---

| | | | |
|:---|:---|:---|:---|
| | **Years Ended December 31,** | **Years Ended December 31,** | **Years Ended December 31,** |
| | **2025** | **2024**<sup>(1)</sup> | **2023** |
| | **(Dollars in millions)** | **(Dollars in millions)** | **(Dollars in millions)** |
| Interest expense: |  |  |  |
| &nbsp;&nbsp;&nbsp;Gross interest expense | $815 | 855 | 480 |
| &nbsp;&nbsp;&nbsp;Capitalized interest | (64) | (36) | (22) |
| Total interest expense | $751 | 819 | 458 |

---

______________________________________________________________________

<sup>(1)</sup> The increase in interest expense for the year ended December 31, 2024 was primarily driven by an increase in average outstanding long-term debt of approximately $780 million.

**Covenants**

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

The debt covenants applicable to Level 3 Financing and its subsidiaries could have a material adverse impact on their ability to operate or expand their respective businesses, to pursue strategic transactions, or to otherwise pursue their plans and strategies.

Certain of Lumen's and our debt instruments contain cross payment default or cross acceleration provisions. When present, these provisions could have a wider impact on liquidity than might otherwise arise from a default or acceleration of a single debt instrument.

The ability of Level 3 Financing and its subsidiaries to comply with the covenants in its debt instruments could be adversely impacted by a wide variety of events, including unforeseen contingencies, many of which are beyond its control.

------

**Compliance**

As of December 31, 2025, we believe we were in compliance with the provisions and financial covenants contained in our debt agreements in all material respects.

**Subsequent Event**

***Senior Secured Notes***

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

During 2024, we initiated marketing our Broomfield, Colorado office buildings to locate a buyer and have classified those buildings as held for sale resulting in an impairment loss of $80 million.

**Asset Retirement Obligations**

As of December 31, 2025 and 2024, our asset retirement obligations consisted primarily of restoration requirements for leased facilities. Asset retirement obligations are included in other long-term liabilities on our consolidated balance sheets.

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

------

**Note 10 — Severance**

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

During April 2024, we reduced our workforce by approximately 7% as a part of our efforts to change our workforce composition to reflect our ongoing transformation and cost reduction opportunities that align with our shapeshifting and focus on our strategic priorities. As a result of this plan, we incurred severance and related costs of approximately $37 million during the second quarter of 2024. We have not incurred, and do not expect to incur, any material impairment or exit costs related to this plan.

We report severance liabilities within accrued expenses and other liabilities - salaries and benefits in our consolidated balance sheets and report severance expenses in selling, general and administrative expenses in our consolidated statements of operations.

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

---

| | | |
|:---|:---|:---|

**Note 11 — Employee Benefits**

**Defined Contribution Plans**

Lumen Technologies sponsors a qualified defined contribution plan covering substantially all of our employees. Under this plan, employees may contribute a percentage of their annual compensation up to certain maximums, as defined by the plan and by the Internal Revenue Service ("IRS"). Currently, we match a percentage of our employee's contributions in cash. For the years ended December 31, 2025, 2024 and 2023, we recognized $32 million, $30 million, and $32 million, respectively, in expense related to this plan.

**Defined Benefit Plans**

We have certain contributory and non-contributory employee pension plans, which are not significant to our financial position or operating results. We recognize in our consolidated balance sheets the funded status of our qualified defined benefit post-retirement plan, which is measured as the difference between the fair value of the plan assets and the plan benefit obligations. We are also required to recognize changes in the funded status within accumulated other comprehensive income, net of tax, to the extent such changes are not recognized in earnings as components of periodic net benefit cost.

------

The following table presents the funded status of our qualified defined benefit plan as of December 31, 2025 and 2024:

---

| | | |

| Benefit obligation | 35 | 35 |
| Funded status | $1 | 2 |

---

The plan was fully funded as of December 31, 2025 and December 31, 2024.

**Note 12 — Fair Value of Financial Instruments**

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

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

We determined the fair values of our long-term debt, including the current portion, based primarily on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB are generally as follows:

---

| | |
|:---|:---|
| **Input Level** | **Description of Input** |
| Level 1 | Observable inputs such as quoted market prices in active markets. |
| Level 2 | Inputs other than quoted prices in active markets that are either directly or indirectly observable. |
| Level 3 | Unobservable inputs in which little or no market data exists. |

---

The following table presents the carrying amounts and estimated fair values of our financial liabilities as of December 31, 2025 and 2024, as well as the input level used to determine the fair values indicated below:

The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows:

---

Of the $16 million net deferred tax assets and $283 million net deferred tax liabilities as of December 31, 2025 and 2024, respectively, $94 million and $337 million is reflected as a long-term liability, in Other liabilities on our consolidated balance sheets and $110 million and $54 million is reflected as a net noncurrent deferred tax asset, in Other assets, net on our consolidated balance sheets.

Income taxes paid, net are as follows:

As of December 31, 2025, we had gross federal NOLs net of uncertain tax positions of $3.6 billion, which will expire between 2026 and 2037 if unused, and state NOLs net of uncertain tax positions of $3.9 billion. Our deferred tax asset balance is based on our historical balance and subsequent standalone activity since we were acquired by Lumen in 2017 and does not correspond to the amount of NOLs that are available for use by Lumen.

We establish valuation allowances when necessary to reduce the deferred tax assets to amounts we expect to realize. As of December 31, 2025, a valuation allowance of $107 million was recorded as it is more likely than not that this amount of tax attribute will not be utilized prior to expiration. Our valuation allowance as of December 31, 2025 and 2024 are primarily related to state NOL carryforwards.

A reconciliation of the change in our gross unrecognized tax benefits (excluding both interest and any related federal benefit) for the years ended December 31, 2025 and 2024 is as follows:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| | **(Dollars in millions)** | **(Dollars in millions)** |
| Unrecognized tax benefits at beginning of period | $851 | 799 |
| &nbsp;&nbsp;Decrease in tax positions of current year netted against deferred tax assets | (12) | (24) |
| &nbsp;&nbsp;(Decrease) Increase in tax positions of prior periods netted against deferred tax assets | (37) | 91 |
| &nbsp;&nbsp;Decreases related to payments | (1) |  |
| &nbsp;&nbsp;Decrease from the lapse of statute of limitations | (6) | (15) |
| Unrecognized tax benefits at end of period | $795 | 851 |

---

As of December 31, 2025 the total amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate was $708 million. The unrecognized tax benefits also includes tax positions that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes, that would not impact the effective tax rate but could impact cash tax amounts payable to taxing authorities.

We had accrued interest (presented before related tax benefits) of less than $1 million as of December 31, 2025 and $1 million as of December 31, 2024.

------

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

Based on our current assessment of various factors, including (i) the potential outcomes of these ongoing examinations, (ii) the expiration of statute of limitations for specific jurisdictions, (iii) the negotiated settlement of certain disputed issues, and (iv) the administrative practices of applicable taxing jurisdictions, it is reasonably possible that the related unrecognized tax benefits for uncertain tax positions previously taken will not change within the next 12 months. The actual amount of change, if any, will depend on several future developments and events, many of which are outside our control.

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

**Note 14 — Geographic and Customer Concentrations**

For the years ended December 31, 2025 and 2024, all of our assets were in North America. The table below shows our operating revenue for the years ended December 31, 2025, 2024 and 2023 by geographic region:

---

_______________________________________________________________________________

<sup>(1)</sup> Includes revenue prior to closing the sale of the EMEA business on November 1, 2023.

A relatively small number of customers account for a significant percentage of our revenue. Our top ten customers accounted for approximately 21%, 20%, and 18% of our total operating revenue for the years ended December 31, 2025, 2024 and 2023, respectively.

**Note 15 — Affiliate Transactions**

We provide competitive local exchange carrier telecommunications services to our affiliates that we also provide to external customers. We periodically review and update our prices for affiliate network services to align with competitive non-regulated market-based rates charged to external customers, taking into consideration the average third-party customer contract term to which those affiliate services pertain. These services are billed directly to our affiliates and recognized as affiliate revenue on our consolidated statements of operations.

------

Whenever possible, costs are incurred directly by our affiliates for the services they use. When such costs are not directly incurred, they are allocated among all affiliates based upon the most reasonable method, first using cost causative measures, or, if no cost causative measure is available, using a general allocator. Unlike certain other affiliates of Lumen, we do not operate as a shared service company to our affiliates and therefore any allocated affiliate revenue we earn reduces the affiliate charges incurred by us and is presented on a net basis within Operating expenses – affiliates on our consolidated statements of operations. From time to time, we may adjust the basis for allocating the costs of a shared service among affiliates. Any such changes in allocation methodologies are generally applied prospectively.

We also purchase services from our affiliates, including telecommunication services, insurance, flight services and other support services such as legal, regulatory, finance, administration and executive support. Our affiliates charge us for those services using the allocation methodologies described above.

**Affiliate Credit Agreements**

On March 22, 2024, we entered into a $1.2 billion secured revolving credit facility with Lumen Technologies with an 11% interest rate per annum. The principal amount is payable upon demand by us and prepayable by Lumen Technologies at any time, but no later than May 31, 2030, which maturity date may be extended for two additional one-year periods. The facility has covenants and is subject to other limitations, including a collateral agreement.

On March 22, 2024, we amended and restated our unsecured credit facility with Lumen Technologies pursuant to which Lumen Technologies may borrow up to $1.825 billion from us. As of December 31, 2025, the interest rate was 9.99% and is subject to certain adjustments as set forth in the facility (SOFR + 6%). The principal amount is payable upon demand by us and prepayable by Lumen Technologies at any time prior to maturity. The facility has covenants and is subject to other limitations. On September 24, 2024, we further amended and restated this facility to extend the maturity date to November 30, 2032, which may be extended for two additional one-year periods.

The following table presents details of amounts owed to us by Lumen Technologies under the secured and unsecured revolving credit facilities:

---

| | | |
|:---|:---|:---|
| | **December 31, 2025** | **December 31, 2024** |
| | **(Dollars in millions)** | **(Dollars in millions)** |
| Secured revolving credit facility | $1200 | 1200 |
| Unsecured revolving credit facility | 1468 | 1468 |
| Total | $2668 | 2668 |

**Distributions and Contributions**

***2025 Transactions***

In the fourth quarter of 2025, we made a cash distribution of $1.2 billion to Lumen Technologies, thereby reducing equity by the same amount.

***2024 Transactions***

In the first quarter of 2024, we made a distribution of cash to Lumen Technologies in the amount of approximately $1.8 billion, thereby reducing equity by the same amount, which was partially offset by a contribution from Lumen Technologies of $210 million, thereby increasing equity by the same amount. In the fourth quarter of 2024, we made a non-cash distribution to Lumen Technologies in exchange for a reduction in advances to affiliates of $200 million, in addition to a cash distribution of an additional $1.4 billion.

**Affiliate Leases**

For information on affiliate leases, refer to Note 5 — Leases.

------

**Note 16 — Commitments, Contingencies and Other Items**

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

We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Subject to these limitations, as of both December 31, 2025 and December 31, 2024, we had accrued $36 million, in the aggregate for our litigation and non-income tax contingencies which is included in Other current liabilities or Other liabilities in our consolidated balance sheets as of such date. Although we quantify our exposure for certain matters below, we cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $36 million accrual due to the inherent uncertainties and speculative nature of contested proceedings. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.

**Latin American Tax Indemnification and Claims**

In connection with the 2022 divestiture of our Latin American business, the purchaser assumed responsibility for the Brazilian tax claims described in our prior periodic reports filed with the SEC. However, we agreed to indemnify the purchaser for amounts paid with respect to the Brazilian tax claims. The value of this indemnification and others associated with the Latin American business divestiture are included in the indemnification amount as disclosed in Note 12 — Fair Value of Financial Instruments. In addition, there remain other pending proceedings in Brazil, Peru, and other Latin America countries, that, if upheld, could result in a reasonably possible loss of up to approximately $82 million in excess of the amount accrued as of December 31, 2025.

**Huawei Network Deployment Investigations** 

Level 3 has received requests from the following federal agencies for information relating to the use of equipment manufactured by Huawei Technologies Company ("Huawei") in Lumen's networks.

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

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

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

------

**Other Proceedings, Disputes and Contingencies**

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

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

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

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

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

**Contractual Commitments**

***Right-of-Way***

As of December 31, 2025, our future rental commitments and Right-of-Way ("ROW") agreements were as follows:

---

| | |
|:---|:---|

| 2027 | 54 |
| 2028 | 52 |
| 2029 | 41 |
| 2030 | 39 |
| 2031 and thereafter | 295 |
| Total future minimum payments | $600 |

---

***Purchase Commitments***

We have several commitments to a variety of vendors for services to be used in the ordinary course of business. As of December 31, 2025, we expect to purchase the following amounts under these commitments:

------

---

| | |
|:---|:---|
| | **(Dollars in millions)** |

| 2029 through 2030 | 33 |
| 2031 and thereafter | 57 |
| Total purchase commitments | $238 |

---

These amounts do not represent our entire anticipated purchases in the future, but represent only those items for which we are the contractually committed party as of December 31, 2025. In addition to our above-described contractual obligations, our ultimate parent company Lumen Technologies is contractually committed to purchase additional services under arrangements from which we may purchase in the future.

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

None.

**ITEM 9A. CONTROLS AND PROCEDURES** 

**Disclosure Controls and Procedures**

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

**Inherent Limitations of Disclosure Controls and Procedures**

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

**Internal Control Over Financial Reporting**

***Management's Report on Internal Control over Financial Reporting***

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act), a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on our evaluation under the framework of COSO, our management concluded that our internal control over financial reporting was effective as of December 31, 2025.

**Changes in Internal Control Over Financial Reporting**

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

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

Lumen's Audit Committee maintains written procedures that require it to annually review and pre-approve the scope of all services to be performed by the independent auditor. This review includes an evaluation of whether the provision of non-audit services by our independent auditor is compatible with maintaining the auditor's independence in providing audit and audit-related services. The Audit Committee's procedures prohibit the independent auditor from providing any non-audit services unless the service is permitted under applicable law and is pre-approved by the Audit Committee or its Chairman, as applicable. The Chairman is authorized to pre-approve projects if the total anticipated cost of all projects pre-approved by him during any fiscal quarter does not exceed $250,000. The Audit Committee has pre-approved the Company's independent auditor to provide up to $75,000 per quarter of miscellaneous permitted tax matters that do not constitute discrete and separate projects and are not prohibited under applicable law. The Chairman and the Chief Financial Officer are required periodically to advise the full Committee of the scope and cost of projects pre-approved by the Chairman and the cost of all pre-approved miscellaneous permitted tax matters. Although applicable regulations permit Lumen to waive these pre-approval requirements in certain limited circumstances, the Audit Committee did not use these waiver provisions in either 2024 or 2025.
