T-Mobile US Inc

In managing our business and assessing financial performance, we supplement the information provided by our condensed consolidated financial statements with other operating or statistical data and non-GAAP financial measures. These operating and financial measures are utilized by our management to evaluate our operating performance and, in certain cases, our ability to meet liquidity requirements. Although companies in the wireless communications services industry may not define each of these measures in precisely the same way, we believe that these measures facilitate comparisons with other companies in the wireless industry on key operating and financial measures.

Postpaid Accounts

A postpaid account is generally defined as a billing account number that generates revenue. Postpaid accounts generally consist of customers that are qualified for postpaid service utilizing phones, High Speed Internet modems, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and IoT), where they generally pay after receiving service.

The following table sets forth the number of ending postpaid accounts:

Postpaid Net Account Additions

The following table sets forth the number of postpaid net account additions:

Postpaid net account additions decreased 13,000, or 6%, for the three months ended March 31, 2025, primarily from higher account deactivations, including the impact from a growing account base and the temporary impact of current year rate plan optimizations, partially offset by higher gross account additions.

Customers

A customer is generally defined as a SIM number with a unique T-Mobile identifier which is associated with an account that generates revenue. Customers are qualified either for postpaid service utilizing phones, High Speed Internet modems, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and IoT), where they generally pay after receiving service, or prepaid service, where they generally pay in advance of receiving service.

The following table sets forth the number of ending customers:

High Speed Internet customers included in Postpaid other customers were 6,129,000 and 4,634,000 as of March 31, 2025 and 2024, respectively. High Speed Internet customers included in Prepaid customers were 725,000 and 547,000 as of March 31, 2025 and 2024, respectively.

Net Customer Additions (Losses)

The following table sets forth the number of net customer additions (losses):

Total net customer additions increased 210,000, or 18%, primarily from:

•Higher postpaid other net customer additions, primarily due to

•Higher net additions from other connected devices;

•Higher net additions from mobile internet devices; and

•Higher net additions from High Speed Internet; partially offset by

•Increased deactivations from a growing customer base; and

•Lower net additions from wearables; and

•Higher prepaid net customer additions, primarily from higher net additions following the Ka’ena Acquisition and lower prepaid to postpaid migrations, partially offset by continued moderation of prepaid industry growth; partially offset by

•Lower postpaid phone net customer additions from higher churn, primarily driven by the temporary impact of current year rate plan optimizations, increased deactivations from a growing customer base and lower prepaid to postpaid migrations, partially offset by higher gross additions.

•High Speed Internet net customer additions included in postpaid other net customer additions were 387,000 and 346,000 for the three months ended March 31, 2025 and 2024, respectively. High Speed Internet net customer additions included in prepaid net customer additions (losses) were 37,000 and 59,000 for the three months ended March 31, 2025 and 2024, respectively.

Churn

Churn represents the number of customers whose service was deactivated as a percentage of the average number of customers during the specified period further divided by the number of months in the period. The number of customers whose service was deactivated is presented net of customers that subsequently had their service restored within a certain period of time and excludes customers who received service for less than a certain minimum period of time. We believe that churn provides management, investors and analysts with useful information to evaluate customer retention and loyalty.

The following table sets forth the churn:

Postpaid phone churn increased 5 basis points, primarily from the temporary impact of current year rate plan optimizations.

Prepaid churn decreased 7 basis points, primarily driven by the inclusion of prepaid customers associated with the Ka’ena Acquisition with lower churn.

Postpaid Average Revenue Per Account

Postpaid Average Revenue per Account (“ARPA”) represents the average monthly postpaid service revenue earned per account. Postpaid ARPA is calculated as Postpaid revenues for the specified period divided by the average number of postpaid accounts during the period, further divided by the number of months in the period. We believe postpaid ARPA provides management, investors and analysts with useful information to assess and evaluate our postpaid service revenue realization and assists in forecasting our future postpaid service revenues on a per account basis. We consider postpaid ARPA to be indicative of our revenue growth potential given the increase in the average number of postpaid phone customers per account and increases in postpaid other customers, including High Speed Internet, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and IoT).

The following table sets forth our operating measure ARPA:

Postpaid ARPA increased $5.34, or 4%, primarily from:

•An increase in customers per account, including from the continued adoption of High Speed Internet;

•Higher premium services, primarily high-end rate plans, net of contra-revenues for content included in such plans, and discounts for specific affinity groups, such as 55+, military and first responders; and

•The positive impact from prior year rate plan optimizations; partially offset by

•Increased promotional activity; and

•An increase in total High Speed Internet only accounts.

Average Revenue Per User

Average Revenue per User (“ARPU”) represents the average monthly service revenue earned per customer. ARPU is calculated as service revenues for the specified period divided by the average number of customers during the period, further divided by the number of months in the period. We believe ARPU provides management, investors and analysts with useful information to assess and evaluate our service revenue per customer and assist in forecasting our future service revenues generated from our customer base. Postpaid phone ARPU excludes postpaid other customers and related revenues, which include High Speed Internet, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and IoT).

The following table sets forth our operating measure ARPU:

Postpaid Phone ARPU

Postpaid phone ARPU increased $0.59, or 1%, primarily from:

•Higher premium services, primarily high-end rate plans, net of contra-revenues for content included in such plans, and discounts for specific affinity groups, such as 55+, military and first responders; and

•The positive impact from prior year rate plan optimizations; partially offset by

•Increased promotional activity, including the success of bundled offerings and continued growth in T-Mobile for Business customers with lower ARPU given large account sizes.

Prepaid ARPU

Prepaid ARPU decreased $2.51, or 7%, primarily from the inclusion of prepaid customers with lower ARPU associated with the Ka’ena Acquisition.

Adjusted EBITDA and Core Adjusted EBITDA

Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization, stock-based compensation and certain expenses, gains and losses, which are not reflective of our ongoing operating performance (“Special Items”). Special Items include Sprint Merger-related costs, UScellular Merger-related costs, certain legal-related expenses, restructuring costs not directly attributable to the Sprint Merger or UScellular Merger (including severance), and other non-core gains and losses. Core Adjusted EBITDA represents Adjusted EBITDA less device lease revenues. Adjusted EBITDA margin represents Adjusted EBITDA divided by Service revenues. Core Adjusted EBITDA margin represents Core Adjusted EBITDA divided by Service revenues.

Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA and Core Adjusted EBITDA margin are non-GAAP financial measures utilized by our management, including our chief operating decision maker, to monitor the financial performance of our operations and allocate resources of the Company as a whole. We historically used Adjusted EBITDA, and we currently use Core Adjusted EBITDA internally as a measure to evaluate and compensate our personnel and management for their performance. We use Adjusted EBITDA and Core Adjusted EBITDA as benchmarks to evaluate our operating performance in comparison to our competitors. Management believes analysts and investors use Adjusted EBITDA and Core Adjusted EBITDA as supplemental measures to evaluate overall operating performance and to facilitate comparisons with other wireless communications services companies because they are indicative of our ongoing operating performance and trends by excluding the impact of interest expense from financing, non-cash depreciation and amortization from capital investments, non-cash stock-based compensation, and Special Items. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes for the transition in the Company’s device financing strategy, by excluding the impact of device lease revenues from Adjusted EBITDA, to align with the exclusion of the related depreciation expense on leased devices from Adjusted EBITDA. Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA and Core Adjusted EBITDA margin have limitations as analytical tools and should not be considered in isolation or as substitutes for income from operations, net income or any other measure of financial performance reported in accordance with GAAP.

The following table illustrates the calculation of Adjusted EBITDA and Core Adjusted EBITDA and reconciles Adjusted EBITDA and Core Adjusted EBITDA to Net income, which we consider to be the most directly comparable GAAP financial measure:

(1)Stock-based compensation includes payroll tax impacts and may not agree with stock-based compensation expense on the condensed consolidated financial statements. Additionally, certain stock-based compensation expenses associated with the Sprint Merger have been included in Sprint Merger-related costs.

(2)UScellular Merger-related costs generally include pre-merger consulting and legal fees.

(3)Legal-related expenses, net, consists of the settlement of certain litigation and compliance costs associated with the August 2021 cyberattack and is presented net of insurance recoveries.

(4)Other, net, primarily consists of certain severance, restructuring and other expenses, gains and losses, not directly attributable to the Sprint Merger or UScellular Merger, which are not reflective of T-Mobile’s core business activities and are, therefore, excluded from Adjusted EBITDA and Core Adjusted EBITDA.

NM - Not meaningful

Core Adjusted EBITDA increased $641 million, or 8%, for the three months ended March 31, 2025. The components comprising Core Adjusted EBITDA are discussed further above.

The increase was primarily from:

•Higher Total service revenues; and

•Higher Equipment revenues, excluding lease revenues; partially offset by

•Higher Cost of equipment sales; and

•Higher Selling, general and administrative expenses, excluding Special Items.

Adjusted EBITDA increased $607 million, or 8%, for the three months ended March 31, 2025, primarily due to the increase in Core Adjusted EBITDA, discussed above, partially offset by lower lease revenues, which decreased $34 million for the three months ended March 31, 2025.

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations, proceeds from issuance of debt, financing leases, the sale of certain receivables, the Revolving Credit Facility (as defined below) and an unsecured short-term commercial paper program. Further, the incurrence of additional indebtedness may inhibit our ability to incur new debt in the future to finance our business strategy under the terms governing our existing and future indebtedness.

Cash Flows

The following is a condensed schedule of our cash flows:

Operating Activities

Net cash provided by operating activities increased $1.8 billion, or 35%, primarily from:

•A $1.1 billion decrease in net cash outflows from changes in working capital, primarily due to lower use of cash from Accounts payable and accrued liabilities, Accounts receivable and Short- and long-term operating lease liabilities, partially offset by higher use of cash from Inventory, Equipment installment plan receivables and Other current and long-term assets; and

•A $663 million increase in Net income, adjusted for non-cash income and expenses.

•Net cash provided by operating activities includes the impact of the Pledge Amendments as described below.

•Net cash provided by operating activities includes the impact of $61 million and $293 million in net payments for Sprint Merger-related costs for the three months ended March 31, 2025 and 2024, respectively.

Investing Activities

Net cash used in investing activities increased $1.6 billion, or 91%. The use of cash was primarily from:

•$2.5 billion in Purchases of property and equipment, including capitalized interest, from the continued build-out of our nationwide 5G network; and

•$727 million of cash consideration, net of cash acquired, related to our acquisitions of Vistar and Blis.

Financing Activities

Net cash provided by financing activities increased $4.9 billion from a net use of cash for the three months ended March 31, 2024, to a net source of cash for the three months ended March 31, 2025. The net source of cash was primarily from:

•$7.8 billion in Proceeds from issuance of long-term debt; partially offset by

•$2.5 billion in Repurchases of common stock;

•$1.0 billion in Dividends on common stock;

•$479 million in Repayments of long-term debt;

•$315 million in Repayments of financing lease obligations; and

•$272 million in Tax withholdings on share-based awards.

Cash and Cash Equivalents

As of March 31, 2025, our Cash and cash equivalents were $12.0 billion compared to $5.4 billion at December 31, 2024.

Adjusted Free Cash Flow

Adjusted Free Cash Flow represents Net cash provided by operating activities less cash payments for Purchases of property and equipment, plus Proceeds related to beneficial interests in securitization transactions. Adjusted Free Cash Flow is a non-GAAP financial measure utilized by management, investors and analysts of our financial information to evaluate cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business. Adjusted Free Cash Flow margin is calculated as Adjusted Free Cash Flow divided by Service revenues. Adjusted Free Cash Flow margin is utilized by management, investors, and analysts to evaluate the Company’s ability to convert service revenue efficiently into cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

The table below provides a reconciliation of Adjusted Free Cash Flow to Net cash provided by operating activities, which we consider to be the most directly comparable GAAP financial measure:

Adjusted Free Cash Flow increased $1.0 billion, or 31%, for the three months ended March 31, 2025, primarily from:

•Higher Net cash provided by operating activities, as described above; and

•Lower Cash purchases of property and equipment, including capitalized interest, driven by planned timing of capital purchases; partially offset by

•Proceeds related to beneficial interests in securitization transactions recognized in the prior year.

•Adjusted Free Cash Flow includes the impact of $61 million and $293 million for the three months ended March 31, 2025 and 2024, respectively, in net payments for Sprint Merger-related costs.

During the three months ended March 31, 2025 and 2024, there were no significant net cash proceeds from securitization.

On October 22, 2024, we executed amendments (the “Pledge Amendments”) to the EIP Sale Arrangement and the Service Receivable Sale Arrangement (as discussed in Note 5 – Sales of Certain Receivables of the Notes to the Condensed Consolidated Financial Statements). Following the effective date of the Pledge Amendments of November 1, 2024, all cash proceeds associated with the sale of such receivables, a portion of which, prior to November 1, 2024, were recognized as Proceeds related to beneficial interests in securitization transactions within Net cash used in investing activities on our Condensed Consolidated Statements of Cash Flows, were recognized as operating cash flows. The Pledge Amendments did not have a net impact on Adjusted Free Cash Flow.

Borrowing Capacity

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $7.5 billion. As of March 31, 2025, there was no outstanding balance under the Revolving Credit Facility.

We maintain an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program supplements our other available external financing arrangements and proceeds are expected to be used for general corporate purposes. As of March 31, 2025, there was no outstanding balance under this program.

Debt Financing

On January 31, 2025, our wholly owned subsidiary, T-Mobile USA, Inc., entered into a credit agreement with certain financial institutions, backed by an Export Credit Agency (the “ECA Facility”), providing for a loan of up to $1.0 billion. On March 17, 2025, we drew down the full $1.0 billion available under the ECA Facility and recognized the net proceeds within Proceeds from issuance of long-term debt on our Condensed Consolidated Statements of Cash Flows.

As of March 31, 2025, our total debt and financing lease liabilities were $88.0 billion, excluding our tower obligations, of which $77.5 billion was classified as long-term debt and $1.1 billion was classified as long-term financing lease liabilities.

During the three months ended March 31, 2025, we issued long-term debt for net proceeds of $7.8 billion, including proceeds from the ECA Facility, and repaid short-term debt with an aggregate principal amount of $479 million.

For more information regarding our debt financing transactions, see Note 8 – Debt of the Notes to the Condensed Consolidated Financial Statements.

License Purchase Agreements

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC (together with Channel 51 License Co LLC, the “Sellers”) in exchange for total cash consideration of $3.5 billion. On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements, pursuant to which we and the Sellers agreed to bifurcate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, whereby we deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent approximately $1.1 billion of the aggregate $3.5 billion cash consideration.

The FCC approved the purchase of the first tranche on December 29, 2023. The first tranche closed on June 24, 2024, and the associated payment of $2.4 billion was made on August 5, 2024.

The FCC approved the purchase of the Dallas licenses included in the second tranche on October 22, 2024. The purchase of the Dallas licenses closed on December 6, 2024, and the associated payment of $541 million was made on the same day.

We anticipate that the remaining deferred licenses from the second tranche of $604 million will close in the second quarter of 2025.

The parties have agreed that each of the closings will occur within 180 days after the receipt of the applicable required regulatory approvals, and payment of each portion of the aggregate $3.5 billion purchase price will occur no later than 40 days after the date of each respective closing.

On September 12, 2023, we entered into a License Purchase Agreement with Comcast (the “Comcast License Purchase Agreement”) pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses are subject to an exclusive leasing arrangement between us and Comcast entered into contemporaneously with the Comcast License Purchase Agreement. On January 13, 2025, we and Comcast entered into an amendment to the Comcast License Purchase Agreement pursuant to which we will acquire additional spectrum. Subsequent to the amendment, the total cash consideration for the transaction is between $1.2 billion and $3.4 billion. We anticipate the closing will occur in the first half of 2028.

On September 10, 2024, we entered into a License Purchase Agreement with N77 License Co LLC (“Buyer”), pursuant to which Buyer has the option to purchase all or a portion of our remaining 3.45 GHz spectrum licenses in exchange for a range of cash consideration, with the specific licenses sold to be determined based upon the amount of committed financing raised by Buyer. As of March 31, 2025, $1.8 billion of the associated licenses have been classified as held for sale at cost and presented in Other current assets on our Condensed Consolidated Balance Sheets. The transaction is subject to receipt of regulatory approvals and is expected to close in the second quarter of 2025. The closing of this transaction is not expected to have a material impact on our Condensed Consolidated Statements of Comprehensive Income.

Lumos Joint Venture

On April 24, 2024, we entered into a definitive agreement with Fund VI to establish a joint venture between us and Fund VI to acquire Lumos from EQT’s predecessor fund, EQT Infrastructure III. Subsequent to March 31, 2025, on April 1, 2025, we completed the joint acquisition of Lumos. At closing, we invested $926 million to acquire a 50% equity interest in the joint venture and fiber customers. The funds invested by us will be used to fund future fiber builds. In addition, pursuant to the definitive agreement, we expect to make an additional capital contribution of approximately $500 million in 2027 or 2028 under the existing business plan.

For more information regarding the Lumos joint venture, see Note 3 – Joint Ventures of the Notes to the Condensed Consolidated Financial Statements.

On May 1, 2024, we completed the Ka’ena Acquisition. The total purchase price is variable, dependent upon specified performance indicators of Ka’ena, and consists of an upfront payment on the Ka’ena Acquisition Date and an earnout payable on August 1, 2026.

Based on the adjusted amount paid upfront, up to an additional $420 million in future cash and T-Mobile common stock is payable in satisfaction of the earnout, dependent upon Ka’ena’s achievement of specified performance indicators.

For more information regarding the Ka’ena Acquisition, see Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements.

On May 24, 2024, we entered into a securities purchase agreement with UScellular pursuant to which, among other things, we will acquire substantially all of UScellular’s wireless operations and select spectrum assets for an aggregate purchase price of approximately $4.4 billion, payable in cash and the assumption of up to $2.0 billion of debt through an exchange offer to certain UScellular debtholders prior to closing. To the extent any debtholders do not participate in the exchange, their bonds will continue as obligations of UScellular, and the cash portion of the purchase price will be correspondingly increased. The transaction is expected to close in mid-2025, subject to customary closing conditions and receipt of certain regulatory approvals.

Following the closing of the transaction, UScellular will retain ownership of its other spectrum, as well as its towers. Subject to the closing of the transaction, we will enter into a 15-year master license agreement to lease space on at least 2,100 towers being retained and to extend our tenancy term on approximately 600 towers where we are already leasing space from UScellular for 15 years post-closing. We estimate the incremental future minimum lease payments associated with the master license agreement will be $1.4 billion over 15 years post-closing.

Metronet Joint Venture

On July 18, 2024, we entered into a definitive agreement with KKR to establish a joint venture to acquire Metronet. This arrangement is expected to close in mid-2025, subject to customary closing conditions and regulatory approvals. At closing, we expect to invest approximately $4.9 billion to acquire a 50% equity interest in the joint venture and all existing residential fiber customers, as well as funding of the joint venture. We do not anticipate making further capital contributions following the closing under the existing business plan.

For more information regarding the Metronet joint venture, see Note 3 – Joint Ventures of the Notes to the Condensed Consolidated Financial Statements.

Upon the completion of certain customary closing conditions, including the receipt of certain regulatory approvals, on February 3, 2025, we completed the Vistar Acquisition, and as a result, Vistar became a wholly owned subsidiary of T-Mobile. In exchange, T-Mobile transferred cash of $621 million.

For more information regarding the Vistar Acquisition, see Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements.

Upon the completion of certain customary closing conditions, including the receipt of certain regulatory approvals, on March 3, 2025, we completed the Blis Acquisition, and as a result, Blis became a wholly owned subsidiary of T-Mobile. In exchange, T-Mobile transferred cash of $180 million.

For more information regarding the Blis Acquisition, see Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We have arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of liquidity. As of March 31, 2025, we derecognized net receivables of $1.6 billion upon sale through these arrangements.

For more information regarding these off-balance sheet arrangements, see Note 5 – Sales of Certain Receivables of the Notes to the Condensed Consolidated Financial Statements.

Future Sources and Uses of Liquidity

We may seek additional sources of liquidity, including through the issuance of additional debt, to continue to opportunistically acquire spectrum licenses or other long-lived assets in private party transactions, make strategic investments, repurchase shares, pay dividends or for the refinancing of existing long-term debt on an opportunistic basis. Excluding liquidity that could be needed for acquisitions of businesses, spectrum and other long-lived assets, or for any potential stockholder returns, we expect our principal sources of funding to be sufficient to meet our anticipated liquidity needs for business operations for the next 12 months, as well as our longer-term liquidity needs. Our intended use of any such funds is for general corporate purposes, including for capital expenditures, spectrum purchases, opportunistic investments and acquisitions, redemption of debt, tower obligations, share repurchases, and dividend payments.

We determine future liquidity requirements for operations, capital expenditures, share repurchases and dividend payments based in large part upon projected financial and operating performance, and opportunities to acquire additional spectrum or repurchase shares. We regularly review and update these projections for changes in current and projected financial and operating results, general economic conditions, the competitive landscape and other factors. We have incurred, and will incur, substantial expenses to comply with the Government Commitments (as defined below), and we have incurred all of the remaining restructuring and integration costs associated with the Sprint Merger, with the cash expenditures for the Sprint Merger-related costs extending beyond 2024. There are a number of additional risks and uncertainties that could cause our financial and operating results and capital requirements to differ materially from our projections, which could cause future liquidity to differ materially from our assessment.

The indentures, supplemental indentures and credit agreements governing our long-term debt to affiliates and third parties, excluding financing leases, contain covenants that, among other things, limit the ability of the Issuers or borrowers and the Guarantor Subsidiaries to incur more debt, create liens or other encumbrances, and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets. We were in compliance with all restrictive debt covenants as of March 31, 2025.

Financing Lease Facilities

We have uncommitted financing lease facilities with certain third parties that provide us with the ability to enter into financing leases for network equipment and services. We expect to enter into up to a total of $1.2 billion in financing lease commitments during the year ending December 31, 2025. As of March 31, 2025, we have entered into $10.2 billion of financing leases under these financing lease facilities, of which $243 million was executed during the three months ended March 31, 2025.

Capital Expenditures

Our liquidity requirements for capital expenditures have been driven primarily by capital expenditures for spectrum licenses, the construction, expansion and upgrading of our network infrastructure, the integration of the networks, spectrum, technology, personnel and customer base of T-Mobile and Sprint, which is substantially complete, and investments in information technology platforms. We expect to maintain our investment in capital expenditures related to these efforts in 2025 compared to 2024, as we continue to build out our nationwide 5G network and our digital transformation. Future capital expenditure requirements will be primarily driven by the deployment of acquired spectrum licenses.

For more information regarding our spectrum licenses, see Note 6 – Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Condensed Consolidated Financial Statements.

Stockholder Returns

On December 13, 2024, we announced that our Board of Directors authorized our 2025 Stockholder Return Program of up to $14.0 billion that will run through December 31, 2025. The 2025 Stockholder Return Program consists of repurchases of shares of our common stock and the payment of cash dividends. The declaration and payment of all dividends is subject to the discretion of our Board of Directors and will depend on financial and legal requirements and other considerations. The amount available under the 2025 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared and paid by us.

The 2025 Stockholder Return Program is consistent with the Company’s capital allocation framework outlined during its Capital Markets Day in September 2024. As discussed at Capital Markets Day, the Company expects its business plan to support approximately $80.0 billion in investments and capital returns between September 18, 2024, and the end of 2027. The Company currently plans to allocate such funds as follows:

•Up to $50.0 billion for share repurchases and cash dividends, which includes the 2025 Stockholder Return Program;

•Approximately $19.0 billion in a discretionary and flexible envelope for potential activities, which may include de-levering, investments in our core business, strategic investments, and/or additional capital returns to stockholders beyond the $50.0 billion initial allocation; and

•Approximately $11.0 billion for announced transactions, including the acquisitions closed during the three months ended March 31, 2025. See Note 2 - Business Combinations, Note 3 - Joint Ventures and Note 6 – Goodwill, Spectrum License Transactions and Other Intangible Assets for additional information.

On November 21, 2024, our Board of Directors declared a cash dividend of $0.88 per share on our issued and outstanding common stock, which was paid on March 13, 2025, to stockholders of record as of the close of business on February 28, 2025.

On February 6, 2025, our Board of Directors declared a cash dividend of $0.88 per share on our issued and outstanding common stock, which will be paid on June 12, 2025, to stockholders of record as of the close of business on May 30, 2025.

During the three months ended March 31, 2025, we paid an aggregate of $1.0 billion in cash dividends to our stockholders, which was presented within Net cash provided by (used in) financing activities on our Condensed Consolidated Statements of Cash Flows. As of March 31, 2025, $993 million for dividends payable is presented within Other current liabilities on our Condensed Consolidated Balance Sheets.

During the three months ended March 31, 2025, we repurchased 10,091,227 shares of our common stock at an average price per share of $244.77 for a total purchase price of $2.5 billion under the 2025 Stockholder Return Program. As of March 31, 2025, we had up to $10.5 billion remaining under the 2025 Stockholder Return Program for repurchases of shares and quarterly dividends through December 31, 2025.

Subsequent to March 31, 2025, from April 1, 2025, through April 17, 2025, we repurchased 1,975,200 shares of our common stock at an average price per share of $259.09 for a total purchase price of $512 million under the 2025 Stockholder Return Program. As of April 17, 2025, we had up to $10.0 billion remaining under the 2025 Stockholder Return Program for repurchases of shares and quarterly dividends through December 31, 2025.

For additional information regarding the 2025 Stockholder Return Program, see Note 12 – Stockholder Return Program of the Notes to the Condensed Consolidated Financial Statements.

Related Party Transactions

We have related party transactions associated with DT, SoftBank or their respective affiliates in the ordinary course of business, including intercompany servicing and licensing.

As of April 17, 2025, DT and SoftBank held, directly or indirectly, approximately 51.8% and 7.5%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 40.7% of the outstanding T-Mobile common stock held by other stockholders. As a result of the Proxy, Lock-Up and ROFR Agreement, dated April 1, 2020, by and between DT and SoftBank, DT has voting control, as of April 17, 2025, over approximately 59.0% of the outstanding T-Mobile common stock.

Disclosure of Iranian Activities under Section 13(r) of the Exchange Act

Section 219 of the Iran Threat Reduction and the Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act. Section 13(r) requires an issuer to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction. Disclosure is required even where the activities, transactions or dealings are conducted outside the U.S. by non-U.S. affiliates in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

As of the date of this report, we are not aware of any activity, transaction or dealing by us or any of our affiliates for the three months ended March 31, 2025, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below with respect to affiliates that we do not control and that are our affiliates solely due to their common control with either DT or SoftBank. We have relied upon DT and SoftBank for information regarding their respective activities, transactions and dealings.

DT, through certain of its non-U.S. subsidiaries, is party to roaming and interconnect agreements with the following mobile and fixed line telecommunication providers in Iran, some of which are or may be government-controlled entities: Irancell Telecommunications Services Company, Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure Company of Iran. In addition, during the three months ended March 31, 2025, DT, through certain of its non-U.S. subsidiaries, provided basic telecommunications services to seven customers in Germany identified on the Specially Designated Nationals and Blocked Persons List maintained by the U.S. Department of Treasury’s Office of Foreign Assets Control: Bank Melli, Europäisch-Iranische Handelsbank, CPG Engineering & Commercial Services GmbH, Golgohar Trade and Technology GmbH, International Trade and Industrial Technology ITRITEC GmbH, The Airline of the Islamic Republic of Iran and Kara Industrial Trading GmbH. These services are in the process of being terminated, in particular by undertaking appropriate legal steps before German courts. For the three months ended March 31, 2025, gross revenues of all DT affiliates generated by roaming and interconnection traffic and telecommunications services with the Iranian parties identified herein were less than $0.1 million, and the estimated net profits were less than $0.1 million.

In addition, DT, through certain of its non-U.S. subsidiaries that operate a fixed-line network in their respective European home countries (in particular, Germany), provides telecommunications services in the ordinary course of business to the Embassy of Iran in those European countries. Gross revenues and net profits recorded from these activities for the three months ended March 31, 2025, were less than $0.1 million. We understand that DT intends to continue these activities.

Separately, SoftBank, through one of its non-U.S. subsidiaries, provides roaming services in Iran through Irancell Telecommunications Services Company. During the three months ended March 31, 2025, SoftBank had no gross revenues from such services, and no net profit was generated. We understand that the SoftBank subsidiary intends to continue such services. This subsidiary also provides telecommunications services in the ordinary course of business to accounts affiliated with the Embassy of Iran in Japan. During the three months ended March 31, 2025, SoftBank estimates that gross revenues and net profit generated by such services were both under $0.1 million. We understand that the SoftBank subsidiary is obligated under contract and intends to continue such services.

In addition, SoftBank, through one of its non-U.S. indirect subsidiaries, provides office supplies to the Embassy of Iran in Japan. SoftBank estimates that gross revenues and net profit generated by such services during the three months ended March 31, 2025, were both under $0.1 million. We understand that the SoftBank subsidiary intends to continue such activities.
