T-Mobile US, Inc. ($TMUS) Soars: Record Q2 Growth & Bullish Guidance Fuel Rally

T-Mobile US, Inc. (TMUS)

Diluted earnings per share ROSE 14% to $2.84, topping estimates of $2.69. Revenue climbed 6% year-over-year to $17.4 billion, slightly exceeding Wall Street forecasts. The company achieved record growth across key metrics, underscoring its momentum in the wireless and broadband markets.

Customer Growth and Revenue Drivers

The company added 830,000 new monthly phone subscribers in Q2, reinforcing its lead in postpaid phone net additions. T-Mobile raised its full-year outlook for total postpaid net additions to 6.1–6.4 million, and for postpaid phone net additions to 2.95–3.1 million. Average Revenue per Account (ARPA) grew over 5%, the highest in eight years, helped by April’s launch of new rate plans and rising adoption of premium offerings.

Service revenue increased by 6% year-over-year, while core adjusted EBITDA also rose by 6%. Adjusted free cash FLOW reached $4.6 billion, an all-time Q2 high. For the full year, free cash flow guidance has been lifted to $17.6–$18 billion.

Network Expansion and Strategic Moves

T-Mobile continues to invest in its network with plans to add nearly 4,000 new sites in 2025. It also launched a $10-per-month satellite texting service that addresses coverage gaps in underserved areas. Despite strong growth, churn rates were slightly elevated in Q2, though the company expects them to stabilize by year-end.

The company highlighted new business group records, driven by strong net additions and a new cable partnership in the SMB segment. It is also expanding into rural markets, although perceptions of its network still lag behind competitors. T-Mobile’s integration of USCellular is ongoing and requires time and capital to fully realize benefits.

Broadband Expansion and Fiber Ambitions

The company’s broadband business added 454,000 high-speed internet users during the quarter. T-Mobile also announced a joint venture with KKR & Co. to acquire Metronet, a fiber-optic internet provider.

Though its fiber expansion trails rivals in scale, the deal positions T-Mobile to grow its wireline footprint.
