T-Mobile Falls 18.2% in 3 Months as Risks Cloud a Potential Rebound

TMUS has shed 18.2% over three months, even as the company posted 33.6% earnings growth and a 7.4% revenue increase to $23.58 billion. That disconnect between fundamentals and price is the core of the setup.

The bull case rests on valuation. TMUS trades at 2.49X EV/Sales, well below its five-year median of 3.17X. Postpaid service revenues rose 9.3%, which supports the argument that the core business is still growing.

The bear case is in the subscriber and cost data. Postpaid account additions slowed to 274,000 from 396,000 a year earlier. Churn rose to 1.09% from 0.97%, a sign that customers are leaving faster. Elevated device costs add pressure on the cost side.

Balance sheet and competition cap the upside. Long-term debt stands at $77.3 billion, and competitive pressures limit the rebound case. Zacks carries TMUS at Rank #3 (Hold), a neutral stance that matches the mixed picture.

Interpretation: the discount to the five-year median EV/Sales may reflect investors pricing in weaker account growth and higher churn rather than ignoring strong earnings. The rebound argument depends on those two metrics stabilizing.
