T-Mobile US (TMUS) Stock Forecast & Price Target

T-Mobile US is supported by a durable share-gain engine built on superior network perception, record customer satisfaction, and disciplined monetization, with postpaid service revenue up 13% Y/Y, EBITDA up 12%, and free cash flow up 4% in the latest reported period. Its scale is reinforced by roughly 87 million postpaid and 26 million prepaid phone customers, about 30% retail wireless share, plus around 9 million fixed-wireless broadband customers and more than 1 million fiber broadband customers through joint ventures, giving it multiple growth vectors beyond core mobility. Even with premium-multiple pressure from competition and satellite overhang, its 0.85% phone churn, strong ARPA trends, raised FCF guidance to $18.4B-$18.8B, and continued buybacks suggest resilient fundamentals and ample capacity to compound value.

T-Mobile US is exposed to execution risk from the Sprint integration and its Challenger strategy, either of which could pressure service quality and operating margins while synergies remain uncertain. Despite serving about 87 million postpaid and 26 million prepaid customers and adding 277,000 postpaid net accounts in Q2, the business faces intense competition from Verizon, AT&T, and cable MVNOs, which limits pricing power and raises the risk of slower growth or churn. Wholesale and other revenue is now expected to be roughly flat, and heavy reliance on fixed-wireless expansion, fiber joint ventures, and wholesale access leaves results vulnerable to capacity constraints, regulatory shifts, and broader macro weakness.
