T-Mobile (TMUS) kicked off 2025 with a powerful first quarter, showcasing continued leadership across both customer and financial metrics, fueled by network innovation and strong execution.

In Q1 2025, total revenues climbed 7% year-over-year to $20.89 billion, while service revenues rose 5% to $16.93 billion. Particularly strong was postpaid service revenue, up 8% to $13.6 billion. Net income surged 24% to $2.95 billion, and diluted EPS jumped 29% to $2.58. Profitability was further reinforced by a healthy 8% increase in Core Adjusted EBITDA to $8.26 billion and a 31% rise in Adjusted Free Cash Flow, totaling $4.40 billion. Operating cash flow also saw significant momentum, up 35% to $6.85 billion.

On the customer side, T-Mobile delivered its best-ever first quarter for postpaid net customer additions with 1.3 million adds, reinforcing its industry leadership. Postpaid phone net adds reached 495,000, and postpaid account net additions totaled 205,000, both leading the sector. The company also maintained dominance in broadband, adding 424,000 High-Speed Internet customers — its 13th straight quarter leading the market in broadband net gains. Postpaid phone churn ticked up slightly to 0.91%, attributed to temporary rate plan adjustments, while prepaid churn improved to 2.68%, helped by the Ka’ena acquisition.

T-Mobile’s technology edge remains sharp. It remains the only U.S. carrier with a nationwide 5G Advanced network built on a standalone core, recently achieving record 6.3 Gbps downlink speeds. The beta launch of T-Satellite, the first U.S. satellite service working on most existing smartphones, has already delivered over a million messages to hundreds of thousands of users across multiple carriers. Further validation came from Opensignal and RootMetrics, with awards for the fastest global download experience and best 5G availability, respectively.

Strategically, T-Mobile continues expanding its reach, completing the acquisition of Lumos while advancing pending deals with UScellular and Metronet. The company is also aggressively returning capital to shareholders, with a $14.0 billion stockholder return program authorized through 2025. In Q1, it repurchased 10.1 million shares for $2.5 billion and paid $1.0 billion in dividends.

Given its strong start, T-Mobile raised its 2025 guidance, now expecting 5.5 to 6.0 million postpaid net customer additions — its highest forecast at this point in the year. Core Adjusted EBITDA is now projected between $33.2 and $33.7 billion, with operating cash flow of $27.0 to $27.5 billion and Adjusted Free Cash Flow reaching $17.5 to $18.0 billion.

CEO Mike Sievert emphasized that the company's best-ever Q1 postpaid growth and strong financial performance reflect T-Mobile’s unwavering customer-first approach, setting the stage for sustained success through innovation and strategic execution.

In short, T-Mobile’s Q1 results showcase a business firing on all cylinders — accelerating customer growth, deepening financial strength, and extending its leadership position in network innovation.
