Our effective interest rate, excluding the impact of derivatives and capitalized interest, was 4.1% on weighted-average debt outstanding of $83.5 billion and $78.6 billion for the three months ended June 30, 2025 and 2024, respectively, and 4.1% on weighted-average debt outstanding of $81.7 billion and $78.0 billion for the six months ended June 30, 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.

Asset-backed Notes

On February 27, 2025, we issued $500 million of 4.740% Class A Senior ABS Notes to third parties in a private placement transaction. Net proceeds of $498 million from these ABS Notes are presented in Proceeds from issuance of long-term debt, net on our Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2025.

As of June 30, 2025, $1.7 billion of our ABS Notes were secured in total by $2.3 billion of gross EIP receivables and future collections on such receivables. Our ABS Notes and the assets securing this debt are included on our Condensed Consolidated Balance Sheets.

The expected maturities of our ABS Notes as of June 30, 2025, were as follows:
(in millions)Expected Maturities
2025$192

Total$1,692 

Variable Interest Entities

In connection with our ABS Notes issuances, 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. Each of 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. Accordingly, we include the balances and results of operations of the ABS Entities on our condensed consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets and liabilities included on our Condensed 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.
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. See Note 15 – Additional Financial Information for our reconciliation of Cash and cash equivalents, including restricted cash.

ECA Facility

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 to finance network equipment-related purchases. The obligations under the 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 and recognized the net proceeds within Proceeds from issuance of long-term debt, net on our Condensed Consolidated Statements of Cash Flows. Borrowings under the ECA facility are amortized semi-annually in equal installments up to the maturity date of March 15, 2036. Interest is based on the Secured Overnight Financing Rate for the interest period plus an applicable margin.
