T-Mobile US

T-Mobile US is one of the three large wireless carriers in the United States. It sells mobile phone plans under the T-Mobile, Metro by T-Mobile and Mint Mobile brands. It also sells home internet over its 5G network, and it adds fiber home internet through joint ventures. It reports one segment, Wireless.

Most of its revenue comes from monthly service fees, and postpaid service revenue was $15.9 billion of $19.0 billion of service revenue in Q2 2026. It also earns money from the sale of phones and other devices. At June 30, 2026, it had 34.7 million postpaid accounts. Deutsche Telekom owns about 53% of the shares and controls the company.

The market prices T-Mobile at a discount because it fears that new competition will end the company's long period of fast growth. On October 8, 2026, SpaceX agreed to buy Grain Management's 800 MHz spectrum, which T-Mobile sold to Grain in August 2026, to make Starlink Mobile a full US carrier. The Wall Street Journal reported a price of about $8 billion. T-Mobile shares fell nearly 10% the next morning.

Growth was already slower: postpaid net account additions fell 13% in Q2 2026 from a year earlier, and the CFO will leave the role in February 2027. For the gap to close, T-Mobile must show that the new competitor does not take its customers. Postpaid net account additions must reach the 2026 guidance of 950,000 to 1.05 million, postpaid account churn must stay near 1%, and Core Adjusted EBITDA and Adjusted Free Cash Flow must reach the raised 2026 guidance. SpaceX must also not start a low-price national service that takes many T-Mobile customers in 2027.

The first test is the Q3 2026 report on October 28, 2026. The Q4 report and the 2027 guidance in early 2027 give the second test, and the FCC review of the SpaceX spectrum purchase gives a third. The fear of a new entrant can last for years, so the gap will probably close only over two to three years of steady results.
