In light of the inherent uncertainties involved in such matters, and based on the information currently available to us, in addition to the previously recorded pre-tax charge of approximately $ 400  million noted above, we believe it is reasonably possible that we could incur additional losses associated with these proceedings and inquiries, and we will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential future actions, may be substantial, and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries could be material to our business, reputation, financial condition, cash flows and operating results.

On June 17, 2022, plaintiffs filed a putative antitrust class action complaint in the Northern District of Illinois, Dale, et al. v. Deutsche Telekom AG, et al. , Case No. 1:22-cv-03189, against DT, T-Mobile, and SoftBank, alleging that the Sprint Merger violated the antitrust laws and harmed competition in the U.S. retail cell service market. Plaintiffs seek injunctive relief and trebled monetary damages on behalf of a purported class of AT&T and Verizon customers whom plaintiffs allege paid artificially inflated prices due to the Sprint Merger. We are vigorously defending this lawsuit, but we are unable to predict the potential outcome.

On January 5, 2023, we identified that a bad actor was obtaining data through a single Application Programming Interface (“API”) without authorization. Based on our investigation, the impacted API is only able to provide a limited set of customer account data, including name, billing address, email, phone number, date of birth, T-Mobile account number and information, such as the number of lines on the account and plan features. The result from our investigation indicates that the bad actor(s) obtained data from this API for approximately 37  million current postpaid and prepaid customer accounts, though many of these accounts did not include the full data set. We believe that the bad actor first retrieved data through the impacted API starting on or around November 25, 2022. We have notified individuals whose information was impacted consistent with state and federal requirements.

In connection with the January 2023 cyberattack, we became subject to consumer class actions and regulatory inquiries, to which we will continue to respond in due course and may incur significant expenses. However, we cannot predict the timing or outcome of any of these potential matters or whether we may be subject to additional legal proceedings, claims, regulatory inquiries, investigations, or enforcement actions.

On February 25, 2025, a purported Company shareholder filed a putative class action and derivative lawsuit in the Delaware Court of Chancery under the caption Palkon v. Deutsche Telekom AG, et al. , Case No. 2025-0211-PAF, against four DT entities, our current directors, and certain of our former directors, asserting breach of fiduciary duty and unjust enrichment claims relating to our 2022 Stock Repurchase Program and our 2023-2024 Stockholder Return Program. We are also named as a nominal defendant in the lawsuit. We are unable to predict the potential outcome of these claims.

Note 19 – Restructuring Costs

UScellular Acquisition Restructuring Initiatives

Upon completing the UScellular Acquisition on August 1, 2025, we began implementing restructuring initiatives to realize cost efficiencies and eliminate redundancies. The major activities associated with the UScellular Acquisition restructuring initiatives will include contract termination costs associated with the rationalization of retail stores, distribution channels, duplicative network and backhaul services and other agreements, severance costs associated with the integration of redundant processes and functions and the decommissioning of certain cell sites and distributed antenna systems to achieve synergies in network costs.

The following table summarizes the expenses incurred in connection with our UScellular Acquisition restructuring initiatives for the year ended December 31, 2025:

(in millions) Expenses Incurred
Contract termination costs $ 32  
Severance costs 63  
Network decommissioning 16  
Total restructuring plan expenses $ 111  

The expenses associated with our UScellular Acquisition restructuring initiatives are included in Cost of services and Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.

(1)    Non-cash items primarily consist of the write-off of assets within Network decommissioning.

The liabilities accrued in connection with our UScellular Acquisition restructuring initiatives are presented in Accounts payable and accrued liabilities on our Consolidated Balance Sheets.

Our UScellular Acquisition restructuring activities are expected to occur over the next two years with substantially all costs incurred by the end of fiscal year 2027. We are evaluating additional restructuring initiatives associated with the UScellular Acquisition, which are dependent on consultations and negotiations with certain counterparties and the expected impact on our business operations, which could affect the amount or timing of the restructuring costs and related payments.

Network Restructuring Initiative

Recent technological advancements have enhanced our Customer-Driven Coverage insights, enabling us to identify, assess and shut down low customer value sites. In the fourth quarter of 2025, we began implementing restructuring initiatives to identify and realize these cost savings on our network, excluding activities associated with the UScellular Acquisition (the “Network Restructuring Initiative”). The major activities associated with the Network Restructuring Initiative include the rationalization of network and backhaul services and the decommissioning of cell sites and distributed antenna systems to reduce our overall network cost.

The following table summarizes the expenses incurred in connection with our Network Restructuring Initiative for the year ended December 31, 2025:

(in millions) Expenses Incurred
Contract termination costs $ 5  
Network decommissioning 64  
Total restructuring plan expenses $ 69  

The expenses associated with our Network Restructuring Initiative are included in Cost of services on our Consolidated Statements of Comprehensive Income.

Our Network Restructuring Initiative also includes the termination of certain of our operating leases for cell sites and switch sites. Incremental expenses associated with terminated leases and leases for which we have recognized accelerated lease expense were $ 24 million for the year ended December 31, 2025, and are included in Cost of services on our Consolidated Statements of Comprehensive Income.

Additionally, we recognized $ 97  million of accelerated depreciation for the year ended December 31, 2025, related to assets associated with the decommissioning of cell sites, which is included in Depreciation and amortization on our Consolidated Statements of Comprehensive Income.

The changes in the liabilities associated with our Network Restructuring Initiative, including expenses incurred and cash payments, are as follows:

Index for Notes to the Consolidated Financial Statements

Our Network Restructuring Initiative is expected to occur over the next two years with a majority of costs incurred by the end of fiscal year 2026. We are evaluating additional restructuring activities associated with the Network Restructuring Initiative, which are dependent on consultations and negotiations with certain counterparties and the expected impact on our business operations, which could affect the amount or timing of the restructuring costs and related payments.

2025 Workforce Transformation

In the fourth quarter of 2025, we began implementing a restructuring initiative to streamline operations by centralizing leaders and teams, reducing organizational layers and eliminating duplicative roles (the “2025 Workforce Transformation”).

We recorded a pre-tax charge of $ 390 million during the year ended December 31, 2025, related to the 2025 Workforce Transformation, which is included in Cost of services and Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.

The changes in the liabilities associated with our 2025 Workforce Transformation initiative, including expenses incurred and cash payments, are as follows:

(in millions) December 31,
2024 Expenses Incurred Cash Payments December 31,
2025
Severance costs $ —   $ 390   $ ( 16 ) $ 374  

The liabilities accrued in connection with our 2025 Workforce Transformation initiative are presented in Accounts payable and accrued liabilities on our Consolidated Balance Sheets.

We have incurred a majority of the costs associated with our 2025 Workforce Transformation initiative, with the remaining costs expected to be substantially incurred by the end of the first quarter of 2026. We expect substantially all associated employee separations and related cash outflows to occur in 2026.

Sprint Merger Restructuring Initiatives

Upon closing the Sprint Merger in April 2020, we began implementing restructuring initiatives to realize cost efficiencies and reduce redundancies. The major activities associated with the Sprint Merger restructuring initiatives included contract termination costs associated with the rationalization of retail stores, distribution channels, duplicative network and backhaul services and other agreements, severance costs associated with the integration of redundant processes and functions and the decommissioning of certain small cell sites and distributed antenna systems to achieve Sprint Merger synergies in network costs.

As of June 30, 2024, we have incurred substantially all restructuring and integration costs associated with the Sprint Merger and, accordingly, no longer separately disclose Sprint Merger-related costs. The cash payments for the Sprint Merger-related costs incurred extend beyond 2025.

The following table summarizes the expenses incurred in connection with our Sprint Merger restructuring initiatives:

(in millions) Year Ended
December 31, 2023 Year Ended
December 31, 2024 Incurred to Date
Contract termination costs $ 45   $ 4   $ 472  
Severance costs 3   —   574  
Network decommissioning 289   91   1,857  
Total restructuring plan expenses $ 337   $ 95   $ 2,903  

The expenses associated with our Sprint Merger restructuring initiatives are included in Cost of services and Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.

Our Sprint Merger restructuring initiatives also included the acceleration or termination of certain of our operating and financing leases for cell sites, switch sites, retail stores, network equipment and office facilities. Incremental expenses associated with terminated leases and leases for which we have recognized accelerated lease expense were $ 91 million and $ 390 million for the years ended December 31, 2024 and 2023, respectively, and are included in Cost of services and Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) designed to ensure information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls are also designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
119

Table of Contents

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Form 10-K.

The certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits 31.1 and 31.2 , respectively, to this Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

In the second quarter of 2025, we began the implementation of a new global enterprise resource planning (“ERP”) system. The implementation is expected to occur in phases over the next several years and will replace many of our operating and financial systems. The ERP system is designed to accurately maintain our financial records, support integrated billing, supply chain and other operational functionality, facilitate data analysis and accelerate information reporting to our management team related to the operation of the business.

As the phased implementation of the new ERP system continues, we could have changes to our processes and procedures which, in turn, could result in changes to our internal control over financial reporting. As such changes occur, we will evaluate quarterly whether such changes materially affect our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions, providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles, providing reasonable assurance that receipts and expenditures are made in accordance with management authorization, and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report herein.
