In 2026, T-Mobile US has shifted from years of heavy capital expenditure to a phase of robust free cash flow generation. After investing more than $30 billion in network build-out since 2020, the company reported free cash flow of $5.2 billion in the first quarter of fiscal 2026, up 18% year-over-year. Management attributes the surge to optimized 5G deployment costs, prudent spectrum acquisitions, and growing ARPU in both wireless and home broadband segments. T-Mobile now covers over 310 million people with Ultra Capacity 5G, servicing more than 9 million broadband customers nationwide. Investors view this pivot as evidence that the integration of Sprint and subsequent infrastructure expansion is finally translating into durable cash yield.

T-Mobile USA has agreed to sell $1.15 billion of 5.000% senior notes due 2036 and $850 million of 5.850% senior notes due 2056 in a registered public offering. Proceeds will be used to refinance existing debt facilities and extend T-Mobile’s debt maturity profile by an average of 12 years. The company expects the transaction to close in early June, subject to customary conditions. Moody’s and S&P have both affirmed T-Mobile’s investment-grade rating at Baa2/BBB, citing improved leverage metrics and ample liquidity—approximately $4.5 billion in unrestricted cash plus a $7.5 billion revolving credit facility. The issuance is projected to reduce annual interest expense by $35 million once the notes fully refinance higher-cost borrowings.
