Summary
Summary of the 8-K filed August 5, 2025. Cited figures are marked; the original filing is the authoritative source.
On August 5, 2025, T-Mobile US, Inc. (TMUS) and its wholly owned subsidiary T-Mobile USA, Inc. settled exchange offers and consent solicitations tied to T-Mobile's acquisition of certain assets from Array Digital Infrastructure, Inc. (formerly United States Cellular Corporation).
The acquisition closed on August 1, 2025. T-Mobile USA issued about $1.68 billiona in aggregate principal of new senior notes in four series, in exchange for roughly $1.58 billion of Array's outstanding notes. The new notes are senior unsecured obligations, guaranteed initially by TMUS and certain wholly owned subsidiaries.
Because this was an exchange rather than a new cash raise, T-Mobile received no cash proceeds. The filing is primarily administrative and does not change TMUS's reported financial results, guidance, or capital allocation. The new notes carry coupons of 5.500%b to 6.700%, with maturities ranging from 2033 to 2070.
The 6.700% notes due 2033 are the shortest and pay semi-annually, while the 2069 and 2070 series pay quarterly and carry 5.500% to 6.250% coupons. The longer-dated issues add significant duration to T-Mobile USA's debt stack, which investors should weigh against the company's leverage profile. Consent fees paid to early tenderers totaled about $1.6 millionc, a small amount relative to the transaction.
Array's bondholders received new T-Mobile obligations with the same economic terms, so the exchange primarily shifts the issuer and credit support rather than changing the coupons. The Form 8-K also files the supplemental indentures, legal opinions, and the August 1, 2025 press release announcing the final results. The principal amounts shown in the filing are stated in dollars, even though some references say 'million'.
Investors should rely on the dollar figures. Overall, the filing confirms the mechanics of integrating Array's legacy debt into T-Mobile's capital structure and should be read as a housekeeping disclosure tied to the closed asset acquisition.

03—Questions
Frequently Asked Questions
Did TMUS receive any new cash from this transaction?
No. The company and T-Mobile USA stated they did not receive any cash proceeds from the exchange offers. The transaction swapped Array's outstanding notes for new T-Mobile USA notes, apart from the small early consent fees paid to tendering holders, which were paid by the company.
Are the new notes different from Array's original notes?
The new notes carry the same coupons and maturities as the Array notes they replaced, based on the series names and rates in the filing. The main change is the issuer and credit support: the obligations now sit at T-Mobile USA and are guaranteed by TMUS and certain subsidiaries. The consent solicitation also modified or eliminated certain notice requirements and restrictive covenants in the old Array indentures.
How large is the debt added to T-Mobile's balance sheet?
The new notes total about $1.68 billion in aggregate principal. This figure reflects the principal amount of the new notes issued in the exchange and is not a new cash borrowing. Investors should check the company's periodic reports for how this affects total debt, leverage ratios, and interest expense.
Will these notes trade publicly?
The 2069, March 2070, and June 2070 notes are expected to trade on Nasdaq's Global Select Market on or promptly after August 5, 2025. The 2033 notes are not intended to be listed on any securities exchange or quoted on any quotation system.
