Special Note Regarding Forward-Looking Statements
This report and other documents filed by us under the federal securities law include, and future oral or written statements or press releases by us and our management may include, forward-looking statements about our business, financial condition, operating results or prospects. These "forward-looking" statements are defined by, and are subject to the "safe harbor" protections under, the federal securities laws. These statements include, among others:
•forecasts of our anticipated future results of operations, cash flows or financial position;
•statements concerning our completed, pending or proposed transactions, investments, product development, transformation plans, participation in government programs, Quantum Fiber initiatives, deleveraging plans, and other initiatives, including benefits or costs associated therewith;
•statements about our liquidity, profitability, profit margins, tax position, 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, investment and expenditure plans, business strategies, debt leverage, capital allocation plans, financing or refinancing alternatives and sources, and pricing plans;
•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, (ii) are inherently speculative and (iii) are subject to a number of risks and uncertainties. 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 below to factors that could cause our actual results to differ materially from those anticipated, estimated, projected or implied by us in those forward- looking statements. These factors include but are not limited to:
•the effects of intense competition from a wide variety of competitive providers, including decreased demand for our more mature service offerings and increased pricing pressures;
•the effects of new, emerging or competing technologies, including those that could make our products less desirable or obsolete;
•our ability to successfully and timely attain our key operating imperatives, including simplifying and consolidating our network, simplifying and automating our service support systems, attaining our Quantum Fiber buildout schedule, replacing aging or obsolete plant and equipment, strengthening our relationships with customers and attaining projected cost savings;
•our ability to safeguard our network, and to avoid the adverse impact of cyber-attacks, security breaches, service outages, system failures, or similar events impacting our network or the availability and quality of our services;
•the effects of ongoing changes in the regulation of the communications industry, including the outcome of legislative, regulatory or judicial proceedings relating to content liability standards, intercarrier compensation, universal service, service standards, broadband deployment, data protection, privacy and net neutrality;

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
References in this report to "QC," "Qwest," "we," "us," and "our" refer to Qwest Corporation and its consolidated subsidiaries. References to "Lumen Technologies" or "Lumen" refers to our ultimate parent company, Lumen Technologies, Inc. and its consolidated subsidiaries, including Level 3 Parent, LLC ("Level 3") and Level 3 Financing, Inc. (“Level 3 Financing”).
Note 1—Background
General
We are a facilities-based technology and communications company that provides a broad array of integrated communications products and services to our business and mass markets customers. Our specific products and services are detailed in Note 3—Revenue Recognition of this report.
We generate the majority of our total consolidated operating revenue from services provided in the 14-state region of Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. We refer to this region as our local service area.
Basis of Presentation
Our consolidated balance sheet as of December 31, 2023, 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 present the results for the interim periods. The consolidated results of operations and cash flows for the first nine 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, 2023.
The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries. 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.
Operating lease assets are included in Other, net under goodwill and other assets on our consolidated balance sheets. Current operating lease liabilities are included in Other under accrued expenses and other liabilities on our consolidated balance sheets. Noncurrent operating lease liabilities are included in Other under deferred credits and other liabilities on our consolidated balance sheets.
We reclassified certain prior period amounts to conform to the current period presentation, including our revenue by product and service categories. See Note 3—Revenue Recognition for additional information. These changes had no impact on total operating revenue, total operating expenses or net income for any period.
During 2023, we identified errors in our previously reported consolidated financial statements related to accounts receivable and accounts payable. The errors are the result of understated revenues from one of our legacy mainframe billing systems and understated network expenses for periods prior to 2021. We have recorded an increase to our retained earnings by $13 million, reflected in our January 1, 2023 and September 30, 2023 retained earnings in our consolidated statements of stockholders' equity in this report. Refer to 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, 2023 for more information.

Table of Contents
Segments
Our operations are integrated into and reported as part of Lumen Technologies. Lumen's chief operating decision maker ("CODM") is our CODM. The CODM reviews our financial information on an aggregate basis only in connection with our quarterly and annual reports that we file with the SEC. Consequently, we do not provide our discrete financial information to the CODM on a regular basis. As such, we have one reportable segment.
Change in Accounting Estimates
Effective January 1, 2024, we changed our method of depreciation and amortization for incumbent local exchange carriers ("ILEC") and certain competitive local exchange carriers ("CLEC") fixed assets from the group method of depreciation to straight line by individual asset method. Historically, we have used the group method of depreciation for the property, plant and equipment and amortization of certain intangible capitalized software assets of our ILECs and certain CLECs. Under the group method, all like kind assets were combined into common pools and depreciated under composite depreciation rates. Recent business divestitures by our parent company and asset sales have significantly reduced our composite asset base. We believe the straight-line depreciation method for individual assets is preferable to the group method as it will result in a more precise estimate of depreciation expense and will result in a consistent depreciation method for all our subsidiaries. This change in the method of depreciation and amortization is considered a change in accounting estimate inseparable from a change in accounting principle. The change in accounting estimate decreased depreciation and amortization expense $30 million, $23 million net of tax, and $78 million, $59 million net of tax, for the three and nine months ended September 30, 2024, respectively.
Additionally, during the first quarter of 2024, we updated our analysis of economic lives of owned fiber network assets. As of January 1, 2024, we extended the estimated economic life and depreciation period of such assets from 25 years to 30 years to better reflect the physical life of the assets that we have experienced and absence of technological changes that would replace fiber. The change in accounting estimate decreased depreciation expense by approximately $6 million, $4 million net of tax, and by $18 million, $13 million net of tax, for the three and nine months ended September 30, 2024, respectively.
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, 2023.
Recently Adopted Accounting Pronouncements
Supplier Finance Programs
On January 1, 2023, we adopted Accounting Standards Update (“ASU”) 2022-04, “Liabilities-Supplier Finance Program (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations” (“ASU 2022-04”). These amendments require that a company that uses a supplier finance program in connection with the purchase of goods or services disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, program activity during the period, changes from period to period and potential magnitude of program transactions. The adoption of ASU 2022-04 did not have any 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” (“ASU 2022-02”). 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 ASU 2022-02 did not have any impact on our consolidated financial statements.
11

Table of Contents
Adoption of Other ASU With No Impact
On January 1, 2024, we adopted ASU 2023-01, “Leases (Topic 842): Common Control Arrangements”, and ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”. The adoption of these ASUs did not have any impact on our consolidated financial statements.
Recently Issued Accounting Pronouncements
In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). This ASU requires public business entities to annually (i) disclose specific categories in the rate reconciliation and (ii) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). ASU 2023-09 will become effective for us in the fiscal year 2025 and early adoption is permitted. As of September 30, 2024, we have not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements, including our annual disclosure within our Income Taxes note.
In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. This ASU will become effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As of September 30, 2024, we have not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements.
Note 2—Goodwill and Other Intangible Assets
Goodwill and other intangible assets consisted of the following:

| September 30, 2024 |  | December 31, 2023
| (Dollars in millions)
Goodwill, less accumulated impairment losses of $2,405 and $2,405 | $ | 6,955 |  |  | 6,955 |
Other intangible assets, less accumulated amortization of $1,964 and $1,966 | $ | 92 |  |  | 103 |

Substantially all of our goodwill was derived from Lumen's acquisition of us where the purchase price exceeded the fair value of the net assets acquired. As of September 30, 2024 and December 31, 2023, the gross carrying amount of goodwill and other intangible assets was $9.0 billion.
We are required to assess our goodwill 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 our reporting unit exceeds its fair value. Our annual impairment assessment date for goodwill is October 31, at which date we assess goodwill at our reporting unit. In reviewing the criteria for reporting units, we have determined that we are one reporting unit.
Second Quarter 2023 Goodwill Impairment Analysis
The sustained decline in Lumen's share price during the second quarter of 2023 was considered a triggering event requiring evaluation of goodwill impairment; as such, we estimated the fair value 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. We selected a revenue multiple within and an EBITDA multiple below these comparable market multiples. For the three months ended June 30, 2023, based on our assessment performed as described above, we concluded that our goodwill was not impaired.
12

Table of Contents
The market approach that we used in the quarter ended June 30, 2023 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.
The amortization expense for finite-lived intangible assets for the three months ended September 30, 2024 and 2023 totaled $4 million and $17 million, respectively, and $29 million and $50 million for the nine months ended September 30, 2024 and 2023, respectively.
We estimate that future total amortization expense for finite-lived intangible assets will be as follows:

| (Dollars in millions)
2024 (remaining three months) | $ | 9 |
2025 | 28 |
2026 | 17 |
2027 | 13 |
2028 | 10 |
2029 and thereafter | 15 |
Total finite-lived intangible assets future amortization expense | $ | 92 |

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 three and nine months ended September 30, 2024, we recognized $14 million and $162 million, respectively, of revenue that was included in contract liabilities of $269 million as of January 1, 2024. During the three and nine months ended of September 30, 2023, we recognized $10 million and $159 million, respectively, of revenue that was included in contract liabilities of $343 million as of January 1, 2023.
Performance Obligations
As of September 30, 2024, we expect to recognize approximately $2.6 billion of revenue in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied. As of September 30, 2024, the transaction price related to unsatisfied performance obligations that are expected to be recognized for the remainder of 2024, 2025 and thereafter was $421 million, $1.1 billion and $1.1 billion, respectively.
These amounts exclude (i) 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 (ii) contracts that are classified as leasing arrangements that are not subject to ASC 606.

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 communications services to customers, including labor and materials consumed for these activities.
Deferred acquisition and fulfillment costs are amortized based on the transfer of services on a straight-line basis over the average contract life of 50 months for mass markets customers and average contract life of 35 months for business customers. Amortized fulfillment costs are included in cost of services and products and amortized acquisition costs are included in selling, general and administrative expenses in our consolidated statements of operations. The amount of these deferred costs that are anticipated to be amortized in the next 12 months are included in Other Current Assets on our consolidated balance sheets. The amount of deferred costs expected to be amortized beyond the next 12 months is included in Other Non-Current Assets on our consolidated balance sheets. Deferred acquisition and fulfillment costs are assessed for impairment on a quarterly basis.
Note 4—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.

Impact of Recent Debt Transactions
On March 22, 2024 (the "Effective Date"), Lumen Technologies, Level 3 Financing, Qwest Corporation and a group of creditors holding a majority of our consolidated debt completed transactions contemplated under the amended and restated transaction support agreement ("TSA") that such parties entered into on January 22, 2024 (the "TSA Transactions"), including (i) the repayment of our term loan maturing 2027 and (ii) the termination, repayment or exchange of previous commitments and debt of our affiliates and the issuance of new term loan facilities, notes, and revolving credit facilities by our affiliates.
During the third quarter of 2024, we repurchased approximately $12 million aggregate principal amount of our senior notes maturing in 2025.
Qwest Guarantees of Lumen Debt
Lumen’s obligations under its new credit agreements entered into on March 22, 2024 and its new superpriority secured senior notes issued on and after March 22, 2024 are unsecured, but Qwest Corporation and certain of its subsidiaries have provided an unconditional unsecured guarantee of payment of Lumen’s obligations under these agreements and senior notes.
Senior Notes and Intercompany Debt
For information about our senior notes and intercompany debt arrangement, see Note 6—Long-Term Debt and Note Payable - Affiliate to the financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2023.
Compliance
As of September 30, 2024, we believe we were in compliance with the financial covenants contained in our material debt agreements in all material respects.
Note 6—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 3% 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 $25 million during the second quarter of 2024. We have not incurred, and do not expect to incur, material impairment or exit costs related to this workforce reduction.
Changes in our accrued liabilities for severance expenses were as follows:

| Severance
| (Dollars in millions)
Balance at December 31, 2023 | $ | 1 |
Accrued to expense | 30 |
Payments, net | (28) |
Balance at September 30, 2024 | $ | 3 |

Note 7—Fair Value of Financial Instruments
Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, advances to and from affiliates, accounts payable and long-term debt, excluding finance lease and other obligations. Due to their short-term nature, the carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, advances to and from affiliates and accounts payable approximate their fair values.
18

Table of Contents
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs using the below-described fair value hierarchy.
We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates.
The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:

Input 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 September 30, 2024 and December 31, 2023, as well as the input level used to determine the fair values indicated below:

|  |  | September 30, 2024 |  | December 31, 2023

Note 8—Affiliate Transactions
We provide incumbent local exchange carrier telecommunications services to our affiliates that we also provide to external customers. These services are priced at regulated rates, where applicable, or otherwise at rates we believe are consistent with non-regulated market-based rates charged to external customers.
We also provide to our affiliates shared services in the form of application development and support services, as well as network support and technical services, and administrative and corporate support. In this regard, we function as a service company to other Lumen affiliates, and correspondingly recognize affiliate revenue based on the costs for the services that we provide to those affiliates.
Whenever possible, costs for shared services are incurred directly by our affiliates for the services they use. When these shared costs are not directly incurred, they are allocated among all affiliates based upon what we determine to be the most reasonable method, first using cost causative measures, or, if no cost causative measure is available, using a general allocator. 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 applied prospectively.

Table of Contents
The following table provides details of affiliate revenue for the three and nine months ended September 30, 2024 and 2023:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2024 |  | 2023 |  | 2024 |  | 2023
| (Dollars in millions)
Direct affiliate revenue | $ | 423 |  |  | 395 |  |  | 1,241 |  |  | 1,189 |
Allocated affiliate revenue | 147 |  |  | 131 |  |  | 435 |  |  | 400 |
Total affiliate revenue | $ | 570 |  |  | 526 |  |  | 1,676 |  |  | 1,589 |

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 these services using the allocation methodologies described above.
Note 9—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 September 30, 2024 and December 31, 2023 we had accrued $17 million and $15 million, respectively, in the aggregate for our litigation and non-income tax contingencies, which are included in Other under Current Liabilities or Other under Deferred Credits and 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 this $17 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.
In this Note, a reference to a "putative" class action means a class has been alleged, but not certified, in that matter.
Principal Proceedings
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 has been removed to the United States District Court Western District of Louisiana Lafayette Division, Case 6:24-CV-01001-RRS-DJA.
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.

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. Plaintiff appealed and the 9th Circuit reversed and remanded. Class certification was contested and ultimately granted in 2023. The 9th 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. If the verdict is not set aside in connection with post-trial motion practice, Lumen will appeal to the 9th Circuit. We have not accrued a contingent liability for this matter. While liability is ultimately possible, we have not determined it to be probable, and cannot estimate any final damages exposure, if any, which remains uncertain.
Billing Practices Suits
In June 2017, a former employee of a Lumen Technologies subsidiary filed an employment lawsuit against Lumen Technologies (at the time named CenturyLink, Inc.) claiming that she was wrongfully terminated for alleging that Lumen charged some of its retail customers for products and services they did not authorize. Thereafter, based in part on the allegations made by the former employee, several legal proceedings were filed, including consumer class actions in federal and state courts, a series of securities investor class actions in federal courts, and several shareholder derivative actions in federal and Louisiana state courts. The derivative cases were brought on behalf of CenturyLink, Inc. against certain current and former officers and directors of the Company and seek damages for alleged breaches of fiduciary duties.
We have settled the consumer and securities investor class actions, and the derivative actions.
Qwest has engaged in discussions regarding related claims with a number of state attorneys general, and has entered into agreements settling certain of the consumer practices claims asserted by several state attorneys general.
Huawei Network Deployment Investigations
Qwest has received requests from the following federal agencies for information relating to the use of equipment manufactured by Huawei Technologies Company ("Huawei") in networks operated by Lumen and Qwest.
•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 naming various defendants and asserting various claims for relief have been filed. To date, three of those name Qwest Corporation as being at fault: Allstate Fire and Casualty Insurance Company, et al., v. Qwest Corp., et al., Case 2023-cv-3048, and Wallace, et al. v. Qwest Corp., et al., Case 2023-cv-30488, both of which have been consolidated with Kupfner, et al., v. Public Service Company of Colorado, et al., Case 2022-cv-30195. The consolidated proceeding is pending in Colorado District Court, Boulder, Colorado, Preliminary estimates of potential damage claims $2 billion.
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 (“PRS”), 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 has 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. Plaintiff has filed a Notice of Appeal and Lumen submitted a cross-appeal as to the original motion to dismiss and motion for summary judgment.
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 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 14—Commitments, Contingencies and Other Items to the financial statements included in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2023. 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 immaterial may ultimately affect us materially.

Note 10—Dividends
From time to time we may declare and pay dividends to our direct parent company, Qwest Services Corporation ("QSC"), sometimes in excess of our earnings to the extent permitted by applicable law. Our debt covenants do not currently limit the amount of dividends we can pay to QSC.
During the nine months ended September 30, 2024 and September 30, 2023, we declared and paid no dividends to QSC. Dividends paid, when applicable, are reflected on our consolidated statements of cash flows as financing activities.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
References in this report to "QC," "Qwest," "we," "us" and "our" refer to Qwest Corporation and its consolidated subsidiaries, unless the context otherwise requires.
All references to "Notes" in this Item 2 of Part I refer to the Notes to Consolidated Financial Statements included in Item 1 of Part I of this report.
Certain statements in this report constitute forward-looking statements. See "Special Note Regarding Forward-Looking Statements" appearing at the beginning of this report and "Risk Factors" referenced in Item 1A of Part II of this report or other of our filings with the SEC for a discussion of certain factors that could cause our actual results to differ from our anticipated results or otherwise impact our business, financial condition, results of operations, liquidity or prospects.
Overview
Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") included herein should be read in conjunction with the information included in our Annual Report on Form 10-K for the year ended December 31, 2023, and with the consolidated financial statements and related notes in Item 1 of Part I of this report. The results of operations for the first nine months of the year are not necessarily indicative of the results of operations that might be expected for the entire year.
We are a facilities-based technology and communications company that provides a broad array of integrated communications products and services to our business and mass markets customers. Our specific products and services are detailed in Note 3—Revenue Recognition in Item 1 of Part I of this report and below under the heading "Products, Services and Revenue".
Our ultimate parent company, Lumen Technologies, Inc., has cash management arrangements or loan arrangements with a majority of its subsidiaries that include lines of credit, affiliate obligations, capital contributions and dividends. As part of these cash management or loan arrangements, affiliates provide lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is advanced on a daily basis for centralized management by Lumen's service company affiliate. From time to time we may declare and pay dividends to Qwest Services Corporation ("QSC"), our direct parent, using cash owed to us under these advances, which has the net effect of reducing the amount of these advances. We report the balance of these transfers on our consolidated balance sheet as advances to affiliates.
At September 30, 2024, we served approximately 1.8 million broadband subscribers. Our methodology for counting broadband subscribers may be different than the methodologies used by other companies.
Macroeconomic Changes
Over the past few years, macroeconomic changes have impacted us and our customers in several ways. On a regular basis, we review and rationalize our lease footprint and may incur accelerated lease costs when we determine to cease using underutilized leased property locations. We did not incur material accelerated lease costs during the nine months ended September 30, 2024.
Additionally, we believe macroeconomic changes over the past few years have resulted in (i) increases in certain revenue streams and decreases in others, (ii) operational challenges resulting from inflation and shortages of certain components and other supplies that we use in our business, (iii) delays in our cost transformation initiatives and (iv) delayed decision-making by certain of our customers. None of these effects, individually or in the aggregate, have to date materially impacted our financial performance or financial position.
Industry developments over the past few years have increased fiber construction demand from customers. The resulting increase in construction labor rates increased the cost of enabling units to be capable of receiving our Quantum Fiber broadband services. From time to time, we believe these factors contributed to a delay in attaining our Quantum Fiber buildout targets.
25

Table of Contents
Continued business uncertainty, supply constraints or inflationary pressures could materially impact our financial results in a variety of ways, including by increasing our expenses, decreasing our revenues, further delaying our network expansion plans or otherwise interfering with our ability to deliver products and services.
We have historically generated revenue by entering into transactions that utilize fiber or other assets, on our network to create custom networks for our customers. We expect the demand for and size of these transactions to grow. We routinely assess revenue-generating opportunities with respect to these assets through right-of-use agreements, leases or other agreements. We may or may not consummate such transactions from time to time, and the revenue from and obligations associated with any such opportunities may be significant, either individually or in the aggregate. The completion of any future transactions may be subject to customary conditions, and may not be executed in a timely manner, or at all.
These above-mentioned macroeconomic factors, coupled with dis-synergies resulting from our affiliates' 2022 and 2023 divestitures, changes in customer preferences and negotiations with our creditors through the end of the first quarter of 2024, placed additional pressures on our financial performance. These developments contributed to us recognizing $2.4 billion in goodwill impairment charges in the fourth quarter of 2023. Some of these pressures continue to impact us. To the extent these pressures continue, we could experience additional deterioration in our projected cash flows, or make significant changes to the assumed discount rates or market multiples that we use to determine the fair value of our reporting unit. Any of these could result in additional future impairments of our approximately $7.0 billion of remaining goodwill.
Products, Services and Revenue
We categorize our products, services and revenue among the following categories:
•Other Broadband, under which we provide primarily lower speed broadband services to residential and small business customers utilizing our copper-based network infrastructure;
•Voice and Other, under which we derive revenues from (i) providing local and long-distance services, professional services, and other ancillary services, (ii) federal broadband and state support payments, and (iii) equipment, IT solutions and other services;
•Fiber Broadband, under which we provide high speed broadband services to residential and small business customers utilizing our fiber-based network infrastructure;
•Harvest, which includes our legacy services managed for cash flow, including Time Division Multiplexing ("TDM") voice and private line services;

Total operating revenue decreased by $87 million and $314 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023. Within each product category, these decreases were primarily due to the following factors:
•Decreases in Other Broadband of $45 million and $132 million, respectively, primarily due to fewer customers for our lower speed copper-based broadband services;
•Decreases in Voice and Other of $16 million and $57 million, respectively, due almost entirely to the continued loss of copper-based voice customers;
•Decreases in Fiber Broadband of $28 million and $76 million, respectively, driven by fewer subscribers for our fiber services, primarily as a result of migrations to the Quantum Fiber services offered by Lumen (which bills customers for such services and pays us for use of our network in providing such services, as further described below);
•Decreases in Harvest of $38 million and $101 million, respectively, primarily attributable to decrease in private line services of $11 million and $33 million, respectively, as well as declines in legacy voice services for business customers of $16 million and $38 million, respectively;
•Decreases in Nurture of $6 million and $27 million, respectively, primarily due to declines in Ethernet services; and
•Decreases in Grow of $8 million for the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023, primarily due to declines in wavelengths services.
Affiliate services revenue increased $44 million and $87 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023 primarily due to $29 million and $53 million increase in fiber broadband and other direct telecommunication services provided to our affiliates, and $15 million and $34 million of additional employee shared services expense allocated to our affiliates.

Cost of Services and Products (exclusive of depreciation and amortization)
Cost of services and products (exclusive of depreciation and amortization) decreased by $27 million and $75 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023. The decrease was primarily due to lower employee-related expenses of $30 million and $77 million.
Selling, General and Administrative
Selling, general and administrative expenses decreased by $7 million and $5 million for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023 due to (i) decreases of $2 million and $16 million, respectively, in marketing and advertising expense, (ii) decreases of $3 million and $12 million, respectively in property and other taxes, and (iii) decreases of $7 million and $15 million in external commissions, respectively. These decreases were partially offset by increases of $6 million and $45 million, respectively, in employee related expenses inclusive of severance costs.
Operating Expenses - Affiliates
Operating expenses - affiliates decreased by $43 million and $25 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023. The decrease for the three and nine months ended September 30, 2024 was primarily due to a decrease of $5 million and $17 million, respectively, in direct telecommunication services charged to us by affiliates and a decrease of $40 million and $10 million for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023, respectively, of lower allocated employee and professional services provided to us by our affiliates.

Amortization | 29 |  |  | 50 |  |  | (42) | %
Total depreciation and amortization | $ | 557 |  |  | 607 |  |  | (8) | %

Depreciation expense decreased by $11 million and $29 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023 primarily due to a decrease of $19 million and $58 million, respectively, resulting from changes in the method of depreciation from the group method of depreciation to the straight line by individual asset method and a decrease of $6 million and $18 million, respectively, due to changes in depreciation lives of fiber assets as discussed in Note 1—Background and Summary of Significant Accounting Policies. These decreases were partially offset by an increase of $12 million and $46 million, respectively, due to net growth in depreciable assets.
Amortization expense decreased by $13 million and $21 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023 primarily due to a decrease of $11 million and $20 million, respectively, associated with changes in the method of amortization from the group method to straight line by individual asset method.

Interest Expense
Interest expense decreased by $12 million and $31 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023. These declines during such periods were primarily due to (i) a decrease of approximately $222 million and $114 million, respectively, in average net outstanding debt and (ii) an increase of capitalized interest of $7 million and $23 million respectively. Additionally, the average interest rate decreased from 6.84% to 6.73% for the three months ended September 30, 2023 as compared to the three months ended September 30, 2024. For the nine months ended September 30, 2024, these decreases were partially offset by an increase in our average interest rate from 6.78% to 6.79% for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2024. See Note 5—Long-Term Debt and Liquidity and Capital Resources below for additional information about our debt.
Interest Income - Affiliate, Net
Interest income - affiliate, net increased by $3 million and $7 million, respectively, for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023. The increase in interest income - affiliate, net was primarily due to a higher average receivable from affiliates during each such period.
Income Tax Expense
For both the three and nine months ended September 30, 2024, our effective tax rates was 26.6%. For the three and nine months ended September 30, 2023, our effective tax rates were 27.0% and 26.3%, respectively.

Liquidity and Capital Resources
Overview of Sources and Uses of Cash
We are an indirect wholly-owned subsidiary of Lumen Technologies, Inc. As such, factors relating to, or affecting, Lumen's liquidity and capital resources could have material impacts on us, including impacts on our credit ratings, our access to capital markets and changes in the financial market's perception of us.
Our ultimate parent company, Lumen Technologies, Inc., has cash management arrangements or loan arrangements with a majority of its subsidiaries that include lines of credit, affiliate obligations, capital contributions and dividends. As part of these cash management or loan arrangements, affiliates provide lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is advanced on a daily basis for centralized management by Lumen's service company affiliate. From time to time we may declare and pay dividends to QSC, our direct parent, sometimes in excess of our earnings to the extent permitted by applicable law, using cash owed to us under these advances, which has the net effect of reducing the amount of these advances. Our debt covenants do not currently limit the amount of dividends we can pay to QSC. Given our cash management arrangement with our ultimate parent, Lumen Technologies, Inc., and the resulting amounts due to us from Lumen Technologies, Inc., a significant component of our liquidity is dependent upon Lumen's ability to repay its obligation to us.
We anticipate that our future liquidity needs will be met through (i) our cash provided by our operating activities, (ii) amounts due to us from Lumen Technologies, (iii) our ability to refinance QC's debt securities to the extent permitted under applicable debt covenants, and (iv) capital contributions, advances or loans from Lumen Technologies or its affiliates if and to the extent they have available funds or access to available funds that they are willing and able to contribute, advance or loan.
In August 2022, the Inflation Reduction Act was signed into law, which, among other things, implemented a corporate alternative minimum tax (“CAMT”) on adjusted financial statement income effective for tax periods occurring after December 31, 2022. The CAMT had no material impact on our financial results as of December 31, 2023. In addition, the Organization for Economic Co-operation and Development has issued Pillar Two model rules introducing a new global minimum tax of 15% intended to be effective on January 1, 2024. While the U.S. has not yet adopted the Pillar Two rules, various other governments around the world are enacting legislation, some of which are effective for tax periods after December 31, 2023. While the global minimum tax will increase our administrative and compliance burdens, we expect that it will have an immaterial impact on our financial statements for the tax period ending December 31, 2024.
Capital Expenditures
We incur capital expenditures on an ongoing basis in order to expand and improve our service offerings, enhance and modernize our networks, fulfill our contractual obligations, and compete effectively in our markets. Lumen Technologies and we evaluate discretionary capital expenditure projects based on a variety of factors, including expected strategic impacts (such as forecasted impact on revenue growth, productivity, expenses, service levels and customer retention) and the expected return on investment. The amount of Lumen’s consolidated capital investment, and our portion thereof, is influenced by, among other things, demand for Lumen’s services and products, our network and customer contract requirements, cash flow generated by operating activities, cash required for debt service and other purposes, regulatory considerations (such as government mandated infrastructure buildout requirements) and the availability of requisite supplies, labor and permits.
Our capital expenditures continue to be focused on enhancing network operating efficiencies, developing new services, and expanding our fiber network, including our Quantum Fiber buildout plan. For more information on our capital spending, see (i) "Cash Flow Activities—Investing" below and (ii) Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2023.

Debt and Other Financing Arrangements
On March 22, 2024, Lumen completed the TSA Transactions with a group of consenting debtholders representing over $15.0 billion of Lumen's outstanding consolidated long-term debt to, among other things, (i) extend maturities of the debt instruments of Lumen and Level 3 Financing, (ii) fund the repayment of all amounts owed under our term loans maturing in 2027 and (iii) provide for us and certain of our subsidiaries to guarantee Lumen’s obligations under its newly-established credit agreements and newly-issued superpriority senior notes. As of September 30, 2024, we had a face amount of approximately $2.0 billion aggregate outstanding indebtedness (excluding finance leases, unamortized premiums, net and unamortized debt issuance costs). $239 million of our outstanding debt is due in the next 12 months (excluding finance lease obligations). For more information on the terms and impact of the TSA Transactions and our consolidated debt, see Note 5—Long-Term Debt to the financial statements included in Item 1 of Part I of this report.
Subject to market conditions, and to the extent permitted under applicable debt covenants, Qwest Corporation may issue debt securities from time to time primarily to refinance a portion of our maturing debt. The availability, interest rate and other terms of any new borrowings will depend on the ratings assigned to Qwest Corporation by credit rating agencies, among other factors.
As of the filing date of this report, the credit ratings for Qwest Corporation's senior unsecured debt were as follows:

Agency | Credit Ratings
Moody's Investors Service, Inc. | Caa3
Standard & Poor's | B-
Fitch Ratings | B+

Lumen's and Qwest Corporation's credit ratings are reviewed and adjusted from time to time by the rating agencies. Any future changes in the senior unsecured or secured debt ratings of us or our subsidiaries could impact our access to capital or borrowing costs. We cannot provide any assurances that we will be able to borrow additional funds on favorable terms, or at all. See Risk Factors—Financial Risks in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2023.
From time to time over the past couple of years, we have engaged in various debt, refinancings, redemptions, tender offers, exchange offers, open market purchases and other transactions designed to reduce our consolidated indebtedness, extend our debt maturities, improve our financial flexibility or otherwise enhance our debt profile. Subject to market conditions, restrictions under our debt covenants, and other limitations, we expect to opportunistically pursue similar transactions in the future to the extent feasible. See Note 5—Long-Term Debt for additional information.
Note Payable - Affiliate
We are permitted to borrow up to $2.0 billion from our parent Lumen Technologies under a revolving promissory note. On September 30, 2022, we repaid all amounts owed to Lumen Technologies under this promissory note. Since that time, we have not owed any amounts to Lumen Technologies under this promissory note.
Dividends
We periodically pay dividends to QSC, our direct parent company, which reduce our capital resources for debt repayments and other purposes. For additional information, see (i) our consolidated statements of cash flows and stockholder's equity, (ii) Note 10—Dividends and (iii) the discussion above under the heading "Overview".

Pension and Post-retirement Benefit Obligations
Lumen Technologies is subject to material obligations under its existing defined benefit pension plans and post-retirement benefit plans. At December 31, 2023, the accounting unfunded status of Lumen's qualified and non-qualified defined benefit pension plans and qualified post-retirement benefit plans was approximately $769 million and approximately $1.9 billion, respectively. For additional information about Lumen's pension and post-retirement benefit arrangements, see "Critical Accounting Policies and Estimates—Pension and Post-Retirement Benefit Obligations" in Item 7 of Lumen's Annual Report on Form 10-K for the year ended December 31, 2023; also see Note 11—Employee Benefits to the consolidated financial statements in Item 8 of Part II of the same report.
A substantial portion of our active and retired employees participate in Lumen's qualified pension plan and post-retirement benefit plans. On December 31, 2014, the Qwest Communications International Inc. ("QCII") pension plan and a pension plan of an affiliate were merged into the CenturyLink Retirement Plan, which is now named the Lumen Combined Pension Plan. Our contributions are not segregated or restricted to pay amounts due to our employees and may be used to provide benefits to other employees of our affiliates. Prior to the pension plan merger, the above-noted employees participated in the QCII pension plan.
Benefits paid by Lumen's qualified pension plan are paid through a trust that holds all of the plan's assets. Based on current laws and circumstances, Lumen Technologies does not expect any contributions to be required for their qualified pension plan during 2024. The amount of required contributions to Lumen's qualified pension plan in 2025 and beyond will depend on a variety of factors, most of which are beyond their control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. Lumen Technologies occasionally makes voluntary contributions in addition to required contributions and reserves the right to do so in the future. Lumen Technologies made a voluntary contribution of $170 million to the trust for the Combined Pension Plan during the third quarter of 2024.
Substantially all of Lumen's post-retirement health care and life insurance benefits plans are unfunded and are paid by Lumen Technologies with available cash.
The affiliate obligations, net shown in Other within current liabilities and noncurrent liabilities on our consolidated balance sheets, primarily represent the cumulative allocation of expenses, net of payments, associated with QCII's pension plans and post-retirement benefits plans prior to the plan mergers. In 2015, we agreed to a plan to settle the outstanding pension and post-retirement affiliate obligations, net balance with QCII over a 30 year term. Under the plan, payments are scheduled to be made on a monthly basis. For the nine months ended September 30, 2024, we made net settlement payments of $39 million to QCII in accordance with the plan. Changes in the affiliate obligations, net are reflected in operating activities on our consolidated statements of cash flows. For the year ended 2024, we expect to make aggregate settlement payments of $52 million to QCII under the plan.
For 2024, Lumen's expected annual long-term rate of return on pension plan assets is 6.5%. However, actual returns, if any, could be substantially different.
For additional information, see “Risk Factors—Financial Risks” in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2023.
Future Contractual Obligations
For information regarding our estimated future contractual obligations, see the MD&A discussion included in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2023.

Federal Broadband Support Programs
In early 2020, the FCC created the Rural Digital Opportunity Fund ("RDOF") program, a federal support program designed to fund broadband deployment in rural America. For the first phase of this program, RDOF Phase I, the FCC awarded $6.4 billion in support payments to be paid in equal monthly installments over 10 years. Lumen Technologies was awarded RDOF funding in several of the states in which we operate and began receiving monthly support payments during the second quarter of 2022, our share of which is not material. In the third quarter of 2024, we relinquished rights to develop certain RDOF census blocks in four states, which resulted in (i) a reduction of the anticipated RDOF Phase I support payments and (ii) the expectation of payment to the Universal Service Administrative Company. These impacts are expected to be immaterial.
For additional information on these programs, see (i) Note 3—Revenue Recognition to our consolidated financial statements in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2023 (ii) "Business—Regulation of Our Business—Universal Service" in Item 1 of Part I of the same Annual Report (iii) "Risk Factors—Legal and Regulatory Risks" in Item 1A of Part I of the same Annual Report and (iv) the periodic reports filed by Lumen Technologies.
Federal officials have proposed changes to current programs and laws that could impact us, including proposals designed to increase broadband access, increase competition among broadband providers, lower broadband costs and increase broadband regulation. 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, various state and federal agencies are continuing to take steps to make this funding available to eligible applicants, including us. Although it remains premature to speculate on the ultimate impact of this legislation on us, we anticipate that the release of this funding would increase competition for broadband customers in newly-served areas.
On April 25, 2024, the FCC adopted “net neutrality” rules regulating broadband internet services as “telecommunications services” in a manner comparable to rules in effect between 2015 and 2018. It is unclear if currently pending legal challenges of these rules will succeed. If the rules withstand these challenges, it is also unclear how the FCC will implement and enforce them. We remain committed to providing open and robust broadband services to all our customers regardless of the applicable regulatory regime. Nonetheless, it is possible that implementation of these new rules could impact our operational, legal and compliance costs.
Cash Flow Activities
The following table summarizes our consolidated cash flow activities for the nine months ended September 30, 2024 and September 30, 2023:

| Nine Months Ended September 30, |  | $ Change
| 2024 |  | 2023 |
| (Dollars in millions)
Net cash provided by operating activities | $ | 1,646 |  |  | 1,822 |  |  | (176) |

Net cash used in financing activities | (288) |  |  | (2) |  |  | 286 |

Operating Activities
Net cash provided by operating activities decreased by $176 million for the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023 primarily due to lower net income adjusted for non-cash income and expenses. Cash provided by operating activities is subject to variability period over period as a result of timing differences, including with respect to collection of receivables and payments of interest expense, accounts payable and bonuses. For additional information about our operating results, see "Results of Operations" above.

Table of Contents
Investing Activities
Net cash used in investing activities decreased by $474 million for the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023 primarily due to a decrease in advances to affiliates, partially offset by a small increase in capital expenditures.
Financing Activities
Net cash used in financing activities increased by $286 million for the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023 due repayment of our term loan maturing in 2027 as well as an increase due to timing of repayments of advances from affiliates.
See Note 5—Long-Term Debt, for additional information on our outstanding debt securities and financing activities.
Other Matters
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 9—Commitments, Contingencies and Other Items for additional information.
Our network includes some residual lead-sheathed copper cables installed years ago. These lead-sheathed cables constitute a small portion of our network. Due to media coverage over the past year of potential health and environmental risks associated with these cables, we anticipate incurring certain investigative costs. We also may incur other costs from related proceedings, including litigation, regulatory initiatives, and remediation. As September 30, 2024, we have not accrued for any such potential costs and will only accrue when such costs are probable and reasonably estimable. For additional information about related litigation and potential risks, see Note 9—Commitments, Contingencies and Other Items to our consolidated financial statements in Item 1 of Part I of this report, and the risk factor disclosures incorporated by reference herein under “Risk Factors” in Item 1A of Part II of this report.
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 September 30, 2024.

ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rule 13a-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 management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. 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 September 30, 2024. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded our disclosure controls and procedures were effective, as of September 30, 2024, in providing reasonable assurance the information required to be disclosed by us in this report was accumulated and communicated in the manner provided above.
Changes in Internal Control Over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the third quarter of 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations of Internal Controls
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.
