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

General

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

Basis of Presentation

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

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

To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows: (i) income attributable to noncontrolling interests in other income, net, (ii) equity attributable to noncontrolling interests in additional paid-in capital, and (iii) cash flows from transactions attributable to noncontrolling interests in other, net financing activities.

We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting. See Note 4—Revenue Recognition and Note 11—Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses or net (loss) income for any period.
Summary of Significant Accounting Policies

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

Assets Held for Sale

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

Recently Adopted Accounting Pronouncements

Segments

We adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” for the year ended December 31, 2024. This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies quantitative thresholds to determine reportable segments. Refer to Note 11—Segment Information for more information on our segment reporting.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (the "FASB") issued ASU 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments." This ASU clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. This standard is effective for the annual period of fiscal 2026 and early adoption is permitted. As of June 30, 2025, we did not have any outstanding convertible debt instruments and do not expect this ASU will have any impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses." This ASU requires additional footnote disclosure of the details of certain income statement expense line items as well as additional disclosure about selling expenses. This standard is effective for the annual period of fiscal 2027 and early adoption is permitted. The guidance will be applied prospectively, with the option for retrospective application. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU requires that public business entities must annually (1) disclose specific categories in their rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU will become effective for us for the annual reporting period ending December 31, 2025. The Income Taxes footnote to the consolidated financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2025 will align with the standard. We do not anticipate this standard will affect our operating results.

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

Discontinued Operations and Disposal Groups [Abstract]  
Planned Divestiture of the Mass Markets Fiber-to-the-Home Business
Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business

On May 21, 2025, we entered into a definitive agreement to sell our Mass Markets fiber-to-the-home business in 11 states to AT&T for a pre-tax total of $5.75 billion in cash, subject to working capital and various other purchase price adjustments.

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

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

As of June 30, 2025 in the accompanying consolidated balance sheet, the assets and liabilities of the disposal group are classified as held for sale and measured at the lower of (i) the carrying value when we classified the disposal group as held for sale or (ii) the fair value of the disposal group, less costs to sell. Effective with the designation of the disposal group as held for sale on May 21, 2025, we suspended recording depreciation of property, plant and equipment while these assets are classified as held for sale. We estimate that we would have recorded an additional $22 million of depreciation for the three and six months ended June 30, 2025, if the disposal group did not meet the held for sale criteria.

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

The principal components of the held for sale assets and liabilities of the disposal group as of June 30, 2025 are as follows:

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

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

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

We are required to assess our goodwill and other indefinite-lived intangible assets for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. We are required to write down the value of goodwill only when our assessment determines the carrying value of equity of any of our reporting units exceeds its fair value. Our annual impairment assessment date for goodwill is October 31, at which date we assess our reporting units.

On May 21, 2025 (the date we agreed to sell the disposal group), we had three reporting units: (i) Mass Markets, (ii) North American Business ("NA Business"), and (iii) Asia Pacific region ("APAC"). Our reporting units are not discrete legal entities with discrete full financial statements. Our assets and liabilities are deployed in, and relate to the operations of, multiple reporting units. When we assess goodwill for impairment, we compare the estimated fair value of each reporting unit's equity to the carrying value of equity that we assign to the reporting unit. If the estimated fair value of the reporting unit is greater than the carrying value, we conclude that no impairment exists. If the estimated fair value of the reporting unit is less than the carrying value, we record a non-cash impairment charge equal to the excess amount. Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours.
We determined that the classification of the Mass Markets fiber-to-the-home business as held for sale as described in Note 2—Planned Divestiture of the Mass Markets Fiber-to-the-Home Business was considered an event or change in circumstance which required an assessment of our goodwill for impairment as of April 30, 2025. We performed a pre-classification goodwill impairment assessment, as of April 30, 2025, using the market approach to test for impairment prior to the classification of these assets as held for sale and to determine the fair value of our Mass Markets reporting unit for the assignment of goodwill held for sale. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry which supported a range of fair values derived from annualized revenue and earnings before interest, tax, depreciation and amortization ("EBITDA") multiples between 1.8x and 3.1x and 5.8x and 8.0x, respectively. We reconciled the estimated fair values of the reporting units to our market capitalization as of April 30, 2025 and concluded that the indicated control premium of approximately 42% was reasonable based on recent market transactions. We concluded no impairment existed at any of our reporting units as of our April 30, 2025 assessment date.

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

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

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

Operating Lease Revenue

We lease various dark fiber and conduit, office facilities, colocation facilities, switching facilities, other network sites, and service equipment to third parties under operating leases. Lease and sublease income are included in Operating revenue in the consolidated statements of operations.

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

(2)     As of June 30, 2025, this amount excluded $30 million of contract liabilities associated with the disposal group reclassified as held for sale.

Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation, and maintenance charges that are deferred and recognized over the actual or expected contract term, which typically ranges from one to five years depending on the service. Contract liabilities are included within Deferred revenue on our consolidated balance sheets. During the three and six months ended June 30, 2025, we recognized $71 million and $365 million, respectively, of revenue that was included in contract liabilities of $733 million as of January 1, 2025, including contract liabilities that were classified as held for sale. During the three and six months ended June 30, 2024, we recognized $43 million and $343 million of revenue that was included in contract liabilities of $698 million as of January 1, 2024.

Performance Obligations

As of June 30, 2025, we expect to recognize approximately $6.0 billion of revenue in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied. As of June 30, 2025, the transaction price related to unsatisfied performance obligations that are expected to be recognized for the remainder of 2025, 2026, and thereafter was $1.6 billion, $2.1 billion and $2.3 billion, respectively.

These amounts exclude (i) the value of unsatisfied performance obligations for contracts for which we recognize revenue in amounts for which we have the right to invoice for services performed (for example, uncommitted usage or non-recurring charges associated with professional or technical services to be completed), (ii) contracts that are classified as leasing arrangements or government assistance that are not subject to ASC 606, and (iii) the value of unsatisfied performance obligations for contracts which relate to the disposal group classified as held for sale.

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

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

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

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

2024 Debt Transactions

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

Lumen Credit Agreements

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

Lumen may prepay amounts outstanding under the Series B Revolving Credit Facility or Lumen TLA at anytime without premium or penalty. If no amounts are outstanding under the Series B Revolving Credit Facility, Lumen may prepay amounts outstanding under the Series A Revolving Credit Facility without premium or penalty.
Both of the Revolving Credit Facilities mature on June 1, 2028 (in each case subject to a springing maturity in certain circumstances). The Lumen TLA matures on June 1, 2028 and requires Lumen to make quarterly amortization payments of 1.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions.

The Lumen TLB requires Lumen to make quarterly amortization payments of 0.25% of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions.

As of June 30, 2025, no borrowings were outstanding under Lumen’s (i) Series A Revolving Credit Facility, with commitments of approximately $489 million, or (ii) Series B Revolving Credit Facility, with commitments of approximately $465 million.

Level 3 Financing Credit Agreement

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

Borrowings under the term loan facility will be, at Level 3 Financing’s option, either (i) the base rate (which is the highest of (x) the overnight federal funds rate, plus 0.50%, (y) the prime rate on such day, and (z) the one-month SOFR published on such date, plus 1.00%), plus an applicable margin, or (ii) one-, three- or six-month SOFR, plus an applicable margin. The applicable margin for SOFR loans under the term loan facility will be 4.25%. The term loan facility is subject to a SOFR floor of 0.50%.

Level 3 Financing may voluntarily prepay loans or reduce commitments under the Level 3 Credit Agreement, in whole or in part, subject to minimum amounts, with prior notice, but without premium or penalty (other than a 1.00% premium on any prepayment in connection with a repricing transaction prior to September 27, 2025). Level 3 Financing is required to prepay borrowings under the term loan facility with 100% of the net cash proceeds of certain asset sales and 100% of the net cash proceeds of certain debt issuances, in each case subject to certain exceptions.

Senior Notes of Lumen and its Subsidiaries

The Company’s consolidated indebtedness at June 30, 2025 included:

•superpriority senior secured notes issued by Lumen;

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

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

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

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

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

At June 30, 2025, we had $234 million undrawn letters of credit outstanding, (i) $231 million of which were issued under the Revolving Credit Facilities and (ii) $3 million of which were issued under a separate facility maintained by other Lumen subsidiaries (the full amount of which is collateralized by cash that is reflected on our consolidated balance sheets as restricted cash within Other assets, net).

Certain Guarantees and Security Interests

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

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

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

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

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

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

Lumen

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

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

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

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

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

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

Level 3 Financing

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

Qwest Companies

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

Compliance

As of June 30, 2025, Lumen Technologies, Inc. believes it and its subsidiaries were in compliance with the provisions and financial covenants in their respective material debt agreements in all material respects.
Guarantees

Lumen does not guarantee the debt of any unaffiliated parties, but, as noted above, as of June 30, 2025, certain of its key subsidiaries have guaranteed on either a secured or unsecured basis (i) Lumen's debt outstanding under its superpriority credit agreements, its superpriority senior secured notes and unsecured senior notes issued by certain other subsidiaries and its $225 million letter of credit facility and (ii) the outstanding term loans, senior secured notes and senior unsecured notes issued by certain other subsidiaries. As further noted above, several of the subsidiaries guaranteeing these obligations have pledged substantially all of their assets to secure certain of their respective guarantees.

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

Our Combined Pension Plan contains provisions that allow us, from time to time, to offer lump sum payment options to certain former employees in settlement of their future retirement benefits. We record an accounting settlement charge, consisting of the recognition of certain deferred costs of the pension plan associated with these lump sum payments, only if in the aggregate they exceed or are probable to exceed the sum of the annual service and interest costs for the plan’s net periodic pension benefit cost, which represents the settlement accounting threshold. The amount of any future non-cash settlement charges will be dependent on several factors, including the total amount of our future lump sum benefit payments.
Benefits paid by the Combined Pension Plan are paid through a trust that holds the Plan's assets. The amount of required contributions to the Combined Pension Plan in 2025 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits, and changes in funding laws and regulations. Based on current laws and circumstances, we do not expect to be required to make any additional contributions in 2025.

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

Our calculation of diluted (loss) earnings per common share excludes non-vested restricted stock awards that are anti-dilutive based upon the terms of the award.

Fair Value of Financial Instruments
Note 10—Fair Value of Financial Instruments

Our financial instruments consist of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, long-term debt (excluding finance lease and other obligations), interest rate swap contracts, certain equity investments, and certain indemnification obligations. Due primarily to their short-term nature, the carrying amounts of our cash, cash equivalents, restricted cash, accounts receivable, and accounts payable approximate their fair values.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs using the below-described fair value hierarchy.

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

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

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

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

Segment Information
Note 11—Segment Information

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

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

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

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

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

The following tables summarize our segment results for the three and six months ended June 30, 2025 and 2024, based on the segment categorization under which we were operating at June 30, 2025.

Revenue and Expenses

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

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

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

•depreciation and amortization expense;

•goodwill or other impairments;

•interest expense;

•stock-based compensation;

•other income and expense items; and

•income tax expense.

Commitments and Contingencies and Other Items
Note 12—Commitments, Contingencies and Other Items

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

We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Subject to these limitations, at June 30, 2025 and December 31, 2024, we had accrued $76 million and $78 million, respectively, in the aggregate for our litigation and non-income tax contingencies, which is included in Other current liabilities or Other liabilities in our consolidated balance sheets as of such dates. We cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of our $76 million accrual at June 30, 2025 due to the inherent uncertainties and speculative nature of contested proceedings. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.

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

Principal Proceedings

Houser Shareholder Suit

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

Lead-Sheathed Cable Litigation

Disclosure Litigation. On September 15, 2023, a purported shareholder of Lumen filed a putative class action complaint originally captioned Glauber, et al. v. Lumen Technologies (now captioned In re Lumen Technologies, Inc. Securities Litigation II, Case 3:23-cv-01290), in the U.S. District Court for the Western District of Louisiana. The complaint alleged that Lumen and certain of its current and former officers violated the federal securities laws by omitting or misstating material information related to Lumen’s responsibility for environmental degradation allegedly caused by the lead sheathing of certain telecommunications cables. The court appointed lead plaintiffs who filed an amended complaint, seeking money damages, attorneys’ fees and costs, and other relief. On March 31, 2025, the court granted Lumen's motion to dismiss plaintiffs' claims with prejudice. On April 30, 2025, the plaintiffs filed an appeal which is captioned McLemore v. Lumen Technologies, Case 25-30264, in the U.S. Court of Appeals for the Fifth Circuit.
Derivative Litigation. On June 11, 2024, a purported shareholder of Lumen filed a shareholder derivative complaint on behalf of Lumen captioned Brown v. Johnson, et al., Case 3:24-cv-00798-TAD-KDM, in the U.S. District Court for the Western District of Louisiana. The complaint alleges claims for breach of fiduciary duty, violations of the federal securities laws, and other causes of action against current and former officers and directors of Lumen relating to placement or presence of lead-sheathed telecommunications cables. The complaint seeks damages, injunctive relief, and attorneys' fees. Substantially similar derivative cases have been filed as follows: (i) on August 9, 2024, Pourarian v. Johnson, et al., Case 3:24-cv-01071-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (ii) on September 9, 2024, Capistrano v. Johnson, et al., Case 3:24-cv-01234-TAD-KMM in the U.S. District Court for the Western District of Louisiana; (iii) on September 16, 2024, Vogel v. Perry, et al., Case 2024-3360 in the 4th Judicial District Court for the Parish of Ouachita, State of Louisiana, subsequently removed on September 17, 2024 to the U.S. District Court for the Western District of Louisiana as Case 3:24-cv-01274-TAD-KMM; and (iv) on September 25, 2024, Murray v. Allen, et al., Case 3:24-cv-01320 in the U.S. District Court for the Western District of Louisiana. In April 2025, the court consolidated the Brown, Pourarian, Capistrano, and Murray actions and stayed the consolidated action pending further developments in In re Lumen Technologies, Inc. Securities Litigation II. In July 2025, the court similarly stayed the Vogel action.

Environmental Litigation

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

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

State Tax Suits

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

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

December 2018 Outage Proceedings

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

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

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

Latin American Tax Litigation and Claims

In connection with the 2022 divestiture of our Latin American business, the purchaser assumed responsibility for the Brazilian tax claims described in our prior periodic reports filed with the SEC. We agreed to indemnify the purchaser for amounts paid with respect to the Brazilian tax claims. The value of this indemnification and others associated with the Latin American business divestiture are included in the indemnification amount as disclosed in Note 10—Fair Value of Financial Instruments.
Huawei Network Deployment Investigations

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

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

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

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

Marshall Fire Litigation

On December 30, 2021, a wildfire referred to as the Marshall Fire ignited near Boulder, Colorado. The Marshall Fire killed two people, and it burned thousands of acres, including entire neighborhoods. Approximately 300 lawsuits seeking relief have been filed naming as defendants our affiliate Qwest Corporation, an additional telecommunications company, and certain power companies. The complaints involving Qwest have been consolidated with Kupfner et al., v. Public Service Company of Colorado, et al., Case 2022-cv-30195 pending in Colorado District Court, Boulder, Colorado. Preliminary estimates of potential damage claims against all defendants exceed $2 billion. A trial to determine liability only has been set for September 2025.

911 Surcharge

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

Minnesota State Income Tax Audit

On May 12, 2025, the Minnesota Department of Revenue issued an order (the "Order") denying the Company's petition for a separate allocation or separate apportionment of the taxable gain resulting from the 2022 divestiture of a portion of our incumbent local exchange carrier ("ILEC") business and making other minor adjustments. The Order seeks to assess additional income tax, penalties, and interest for the 2021 and 2022 income tax year. The Company intends to file a timely notice of appeal of the Order with the Minnesota Tax Court in the third quarter of 2025.

Other Proceedings, Disputes and Contingencies

From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, regulatory hearings relating primarily to our rates or services, actions relating to employee claims, tax issues, or environmental law issues, grievance hearings before labor regulatory agencies, miscellaneous third-party tort actions, or commercial disputes.
We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial within the next 12 months if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers.

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

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

The matters listed in this Note do not reflect all our contingencies. For additional information on our contingencies, see Note 18—Commitments, Contingencies and Other Items to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024. The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings we currently consider insignificant may ultimately affect us materially.

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

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

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

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

Segments

We adopted Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” for the year ended December 31, 2024. This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies quantitative thresholds to determine reportable segments. Refer to Note 11—Segment Information for more information on our segment reporting.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (the "FASB") issued ASU 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments." This ASU clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. This standard is effective for the annual period of fiscal 2026 and early adoption is permitted. As of June 30, 2025, we did not have any outstanding convertible debt instruments and do not expect this ASU will have any impact on our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses." This ASU requires additional footnote disclosure of the details of certain income statement expense line items as well as additional disclosure about selling expenses. This standard is effective for the annual period of fiscal 2027 and early adoption is permitted. The guidance will be applied prospectively, with the option for retrospective application. We are currently evaluating the impact the adoption of this standard will have on our disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU requires that public business entities must annually (1) disclose specific categories in their rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). This ASU will become effective for us for the annual reporting period ending December 31, 2025. The Income Taxes footnote to the consolidated financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2025 will align with the standard. We do not anticipate this standard will affect our operating results.
