(1)Interest is based on the Secured Overnight Financing Rate (“SOFR”) for the interest period plus an applicable margin. The floating rate, including the applicable margin, on the ECA Facility due March 2036 was 4.927% for the interest payment made during the year ended December 31, 2025. No interest was paid on the ECA Facility due November 2036 during the year ended December 31, 2025.

Long-term debt was classified as follows:

Long-term debt to affiliates1,498 1,497 
Total long-term debt$81,147 $74,197 

Our effective interest rate, excluding the impact of derivatives and capitalized interest, was approximately 4.2% and 4.1% on weighted-average debt outstanding of $83.0 billion and $78.3 billion for the years ended December 31, 2025 and 2024, respectively. The weighted-average debt outstanding was calculated by applying an average of the monthly ending balances of total short-term and long-term debt to third parties and short-term and long-term debt to affiliates, net of unamortized premiums, discounts, debt issuance costs and consent fees.

Senior Notes

The Senior Notes are guaranteed on a senior unsecured basis by the Company and certain of our consolidated subsidiaries. They are redeemable at our discretion, in whole or in part, at any time. The redemption price is calculated by reference to the date on which such notes are redeemed and includes a premium, generally until the notes reach a par call date, on or after which they are redeemable at par. The amount of time by which the par call date, where applicable, precedes the maturity date of the respective series of Senior Notes generally varies from one month to three years.

(2)In connection with the closing of the UScellular Acquisition, we became obligated to execute the Exchange Offers of certain senior notes of UScellular pursuant to which T-Mobile notes with an aggregate outstanding principal balance of $1.7 billion were issued with the same interest rate, interest payment dates, maturity dates and redemption terms as each corresponding series of senior notes of UScellular. See Note 2 – Business Combinations for further information regarding the UScellular Acquisition.

Subsequent to December 31, 2025, on January 12, 2026, we issued $1.2 billion of 5.000% Senior Notes due 2036 and $850 million of 5.850% Senior Notes due 2056.

Credit Facilities

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $7.5 billion, including a letter of credit sub-facility of up to $1.5 billion and a swingline loan sub-facility of up to $500 million. As of December 31, 2025 and 2024, we did not have an outstanding balance under the Revolving Credit Facility.

Subsequent to December 31, 2025, on January 5, 2026, we entered into a Second Amended and Restated Credit Agreement (the “January 2026 Credit Agreement”) with certain financial institutions named therein. The January 2026 Credit Agreement amends and restates in its entirety the Amended and Restated Credit Agreement dated as of October 17, 2022. The January 2026 Credit Agreement increases the commitments under the revolving credit facility from $7.5 billion to $10.0 billion and extends the maturity of the commitments to January 5, 2031, except as otherwise extended or replaced.

Subsequent to December 31, 2025, on January 22, 2026, we delivered notices of redemption on $3.0 billion aggregate principal amount of our 4.750% Senior Notes due 2028 and 4.750% Senior Notes to affiliates due 2028. We redeemed the notes at par on February 1, 2026.

Asset-backed Notes

In connection with issuing the ABS Notes, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “ABS BRE”), and a trust (the “ABS Trust” and together with the ABS BRE, the “ABS Entities”), in which the ABS BRE holds a residual interest. The ABS BRE’s residual interest in the ABS Trust represents the rights to all funds not needed to make required payments on the ABS Notes and other related payments and expenses.

Under the terms of the ABS Notes, our wholly owned subsidiary, T-Mobile Financial LLC (“FinCo”), and certain of our other wholly owned subsidiaries (collectively, the “Originators”) transfer EIP receivables to the ABS BRE, which in turn transfers such receivables to the ABS Trust, which issued the ABS Notes. The Class A senior ABS Notes have an expected weighted average life of approximately 2.5 years. Under the terms of the transaction, there is a two-year revolving period during which we may transfer additional receivables to the ABS Entities as collections on the receivables are received. The EIP receivables transferred to the ABS Entities and related assets, consisting primarily of restricted cash, will only be available for payment of the ABS Notes and expenses related thereto, payments to the Originators in respect of additional transfers of device payment plan agreement receivables, and other obligations arising from our ABS Notes transactions, and will not be available to pay our other obligations until the associated ABS Notes and related obligations are satisfied. The third-party investors in the Class A senior ABS Notes have legal recourse only to the assets of the ABS Trust securing the ABS Notes and do not have any recourse to T-Mobile with respect to the payment of principal and interest. The receivables transferred to the ABS Trust will only be available for payment of the ABS Notes and other obligations arising from the transaction and will not be available to pay any obligations or claims of T-Mobile’s creditors.

Under a parent support agreement, T-Mobile has agreed to guarantee the performance of the obligations of FinCo, which will continue to service the receivables, and the other T-Mobile entities participating in the transaction. However, T-Mobile does not guarantee any principal or interest on the ABS Notes or any payments on the underlying EIP receivables.

Cash collections on the EIP receivables are required at certain specified times to be placed into segregated accounts. Deposits to the segregated accounts are considered restricted cash and are included in Other current assets on our Consolidated Balance Sheets.

As of December 31, 2025, $2.0 billion of our ABS Notes were secured in total by $2.6 billion of gross EIP receivables and collections on such receivables. Our ABS Notes and the assets securing this debt are included on our Consolidated Balance Sheets.
The expected maturities of our ABS Notes as of December 31, 2025, were as follows:
(in millions)Expected Maturities

Total$2,000 

Variable Interest Entities

The ABS Entities meet the definition of a VIE for which we have determined that we are the primary beneficiary as we have the power to direct the activities of the ABS Entities that most significantly impact their performance. Those activities include selecting which receivables are transferred into the ABS Entities, servicing such receivables, and funding of the ABS Entities. Additionally, our equity interest and residual interest in the ABS BRE and the ABS Trust, respectively, obligate us to absorb losses and give us the right to receive benefits from the ABS Entities that could potentially be significant to the ABS Entities. Accordingly, we include the balances and results of operations of the ABS Entities in our consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets and liabilities included in our Consolidated Balance Sheets with respect to the ABS Entities:

See Note 4 – Receivables and Related Allowance for Credit Losses for additional information on the EIP receivables used to secure the ABS Notes.

Master Receivables Financing Agreement

Subsequent to December 31, 2025, on February 5, 2026, we entered into a master receivables financing agreement with certain third parties that provides for a revolving loan facility secured by pledged service customer relationships, which include current as well as future monthly service receivables, during the borrowing period (the “MRFA”). Concurrently with the execution of the MRFA, we borrowed $1.0 billion with a floating interest rate indexed to SOFR plus an applicable margin, maturing on February 5, 2027, a one-year borrowing period. The net proceeds will be reflected in Proceeds from issuance of short-term debt on our Condensed Consolidated Statements of Cash Flows for the three months ending March 31, 2026.

Spectrum Financing

On April 1, 2020, in connection with the closing of the Sprint Merger, we assumed Sprint’s spectrum-backed notes, which are collateralized by the acquired, directly held and third-party leased Spectrum licenses (collectively, the “Spectrum Portfolio”) transferred to wholly owned bankruptcy-remote special purpose entities (collectively, the “Spectrum Financing SPEs”). As of December 31, 2025 and 2024, the total outstanding obligations under these Notes were $827 million and $1.3 billion, respectively.

In October 2016, certain subsidiaries of Sprint Communications, Inc. transferred the Spectrum Portfolio to the Spectrum Financing SPEs, which was used as collateral to raise an initial $3.5 billion in senior secured notes (the “2016 Spectrum-Backed Notes”) bearing interest at 3.360% per annum under a $7.0 billion securitization program. The 2016 Spectrum-Backed Notes were repayable over a five-year term, with interest-only payments over the first four quarters and amortizing quarterly principal payments thereafter commencing December 2017 through September 2021. We fully repaid the 2016 Spectrum-Backed Notes in 2021.
In March 2018, Sprint issued approximately $3.9 billion in aggregate principal amount of senior secured notes (the “2018 Spectrum-Backed Notes” and together with the 2016 Spectrum-Backed Notes, the “Spectrum-Backed Notes”) under the existing $7.0 billion securitization program, consisting of two series of senior secured notes. The first series of notes totaled $2.1 billion in aggregate principal amount, bearing interest at 4.738% per annum, and had quarterly interest-only payments until June 2021, with additional quarterly principal payments commencing in June 2021 through March 2025, which was fully repaid on January 13, 2025. The second series of notes totaled approximately $1.8 billion in aggregate principal amount, bears interest at 5.152% per annum, and had quarterly interest-only payments until June 2023, with additional quarterly principal payments commencing in June 2023 through March 2028. As of December 31, 2025, $368 million of the aggregate principal amount was classified as Short-term debt on our Consolidated Balance Sheets. The Spectrum Portfolio, which also serves as collateral for the Spectrum-Backed Notes, remains substantially identical to the original portfolio from October 2016.

Simultaneously with the October 2016 offering, Sprint Communications, Inc. entered into a long-term lease with the Spectrum Financing SPEs for the ongoing use of the Spectrum Portfolio. Sprint Communications, Inc. is required to make monthly lease payments to the Spectrum Financing SPEs in an aggregate amount that is market-based relative to the spectrum usage rights as of the closing date and equal to $165 million per month. The lease payments, which are guaranteed by T-Mobile subsidiaries subsequent to the Sprint Merger, are sufficient to service all outstanding series of the 2016 Spectrum-Backed Notes and the lease also constitutes collateral for the senior secured notes. Because the Spectrum Financing SPEs are wholly owned T-Mobile subsidiaries subsequent to the Sprint Merger, these entities are consolidated and all intercompany activity has been eliminated.

Each Spectrum Financing SPE is a separate legal entity with its own separate creditors who will be entitled, prior to and upon the liquidation of the respective Spectrum Financing SPE, to be satisfied out of the Spectrum Financing SPE’s assets prior to any assets of such Spectrum Financing SPE becoming available to T-Mobile. Accordingly, the assets of each Spectrum Financing SPE are not available to satisfy the debts and other obligations owed to other creditors of T-Mobile until the obligations of such Spectrum Financing SPE under the Spectrum-Backed Notes are paid in full. Certain provisions of the Spectrum Financing facility require us to maintain specified cash collateral balances. Amounts associated with these balances are considered to be restricted cash.

Restricted Cash

Certain provisions of our debt agreements require us to maintain specified cash collateral balances. Amounts associated with these balances are considered to be restricted cash.

Commercial Paper

On July 25, 2023, we established 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 December 31, 2025 and 2024, there was no outstanding balance under this program.

Standby Letters of Credit

For the purposes of securing our general purpose obligations and obligations to provide device insurance services, we maintain an agreement for standby letters of credit with certain financial institutions. Our outstanding standby letters of credit were $116 million and $152 million as of December 31, 2025 and 2024, respectively.

ECA Facilities

On January 31, 2025, we entered into a credit agreement with certain financial institutions, backed by an Export Credit Agency (an “ECA Facility”), providing for a loan of up to $1.0 billion to finance network equipment-related purchases (the “ECA Facility due March 2036”). The obligations under this ECA Facility are also guaranteed by us and by all of our wholly owned domestic restricted subsidiaries (subject to customary exceptions). On March 17, 2025, we drew down the full $1.0 billion available under the ECA Facility due March 2036 and recognized the net proceeds within Proceeds from issuance of long-term debt, net on our Consolidated Statements of Cash Flows. Borrowings under this ECA Facility are amortized semi-annually in equal installments up to the maturity date of March 15, 2036. Interest is based on the SOFR for the interest period plus an applicable margin.

On August 29, 2025, we entered into an ECA Facility, providing for a loan of up to $1.0 billion to finance network equipment-related purchases (the “ECA Facility due November 2036”). The obligations under this ECA Facility are also guaranteed by us and by all of our wholly owned domestic restricted subsidiaries (subject to customary exceptions). During the fourth quarter of
2025, we drew down the full $1.0 billion available under the ECA Facility due November 2036 and recognized the net proceeds within Proceeds from issuance of long-term debt, net on our Consolidated Statements of Cash Flows. Borrowings under this ECA Facility are amortized semi-annually in equal installments up to the maturity date of November 30, 2036. Interest is based on SOFR for the interest period plus an applicable margin.
