Customer Receivables and Contract Balances

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

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

Performance Obligations

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

These amounts exclude:

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

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

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

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

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

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

Governmental Funding

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

For both the years ended December 31, 2025 and 2024, Lumen recorded non-customer revenue of $67 million and $83 million, respectively, under government assistance programs, of which 28% and 18%, respectively, was associated with state universal service fund support programs.
The federal government has introduced several programs expand broadband access, including the Rural Digital Opportunity Fund (“RDOF”) program, an FCC initiative that provides federal financial support to fund broadband deployment in rural America. We were awarded RDOF funding in several of the states in which we operate and received payments for a period starting in 2022. We received approximately $17 million in annual RDOF Phase I support payments for the year ended December 31, 2023. In the third quarter of 2024, we relinquished rights to develop certain RDOF census blocks in four states, which resulted in a reduction of the anticipated RDOF Phase I support payments to approximately $16 million for the year ending December 31, 2024. In the second quarter of 2025, we voluntarily relinquished the remainder of our RDOF awards. As a result, we will no longer receive funding through the RDOF program and recognized a reduction to revenue of $46 million in our consolidated statements of operations in the second quarter of 2025. We also incurred fees of $49 million in connection therewith, which are reflected in our operating expenses within our consolidated statements of operations. In January 2026, we paid the $95 million of revenue and fees summarized above, along with an additional $4 million relating to our 2024 relinquishment as repayment of funds previously received and remittance of the fees incurred.

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

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
