What Happened?

T-Mobile US, Inc. stock has fallen about 11% over the past 6 months, recently trading near $211 per share, as investors reassessed the company’s near-term growth outlook despite continued operational strength.

The stock declined primarily because concerns around pricing changes and potential increases in customer churn led investors to lower valuation expectations and compress the stock’s multiple, even as T-Mobile continues to take share from competitors like Verizon and AT&T, which are seeing slower subscriber growth and rely more heavily on pricing and promotions to compete.

This month at the Morgan Stanley Technology, Media & Telecom Conference, CEO Srini Gopalan said T-Mobile’s business is performing in line with expectations for Q1, with service revenue growing about 4x faster than competitors and EBITDA growing about 2x faster, while fixed wireless broadband remained a key growth driver after reaching 8 million customers, doubling its base over the past two years, increasing usage per customer by 30%, and improving speeds by 50%.

Fixed wireless matters because it allows T-Mobile to deliver home internet using its wireless network instead of building expensive cable infrastructure, creating a capital-light and high-margin growth opportunity.

Management also highlighted efficiency gains from digital and AI initiatives, noting the company has already removed 50% of customer care calls on its path toward a 75% reduction target and still expects about $3 billion of efficiency gains by 2027, with Gopalan emphasizing the company’s focus on “best network, best value, best experience.”

Institutional activity remained active and mixed, reflecting both conviction and profit-taking. Wealth Enhancement Advisory Services increased its stake by 7.5% to about 640,661 shares worth $127 million, while Nordea Investment Management added shares to hold over 2 million shares valued near $414 million and Danske Bank initiated a new position worth about $77 million.

At the same time, Park Avenue Securities reduced its stake by 37.4% and Neville Rodie & Shaw cut its holdings by 76.6%, showing selective profit-taking even as large investors continue to build positions.

Is TMUS Undervalued?

Under valuation assumptions, the stock is modeled using:

  • Revenue Growth (CAGR): 5.2%
  • Operating Margins: 25.0%
  • Exit P/E Multiple: 18.7x

Growth is expected to remain steady in the mid-single-digit range, supported by continued postpaid subscriber additions and expansion in fixed wireless broadband, which is becoming an increasingly important contributor to total revenue.

Margin expansion remains a key driver, supported by ongoing cost efficiencies from the Sprint merger, increasing adoption of higher-value premium plans, and digital and AI initiatives that are reducing customer service costs and improving operating leverage.

This suggests earnings growth will be driven more by improving profitability and customer lifetime value than by rapid top-line acceleration, as T-Mobile continues to leverage its network advantage and pricing power.

Based on these inputs, the model estimates a target price of $341, implying about 62% total upside over roughly 3 years, indicating the stock appears undervalued at current levels.

Over the next 12 months, performance is likely to be driven by continued postpaid subscriber growth, expansion in fixed wireless broadband, and further margin improvement as efficiency initiatives scale.

Strong free cash flow generation also supports ongoing share repurchases, which can enhance per-share earnings growth even in a slower revenue environment.

At current levels, T-Mobile appears undervalued, with future performance driven by subscriber growth, margin expansion, and disciplined capital allocation.
