Summary

T-Mobile USA simplified its debt structure by releasing certain subsidiary guarantees across its major debt facilities after repaying legacy indebtedness. The releases affect the company's $10 billion revolving credit facility, senior notes issued under three indentures, export credit agency facilities, and commercial paper program.

The remaining guarantors now consist of parent T-Mobile US and three Sprint entities: Sprint LLC, Sprint Capital Corporation, and Sprint Communications LLC. This is a routine debt structure optimization following the repayment of legacy obligations, likely tied to the ongoing integration of Sprint assets acquired in 2020.

The parent guarantee and key Sprint entity guarantees remain; certain other subsidiaries' guarantees were released, narrowing the guarantor group — the filing does not detail those released entities' asset base, so creditor impact is not characterized either way. The action reflects normal post-merger debt rationalization rather than a change in credit profile or capital allocation strategy. The 8-K is signed by Peter Osvaldik, CFO.
