T-Mobile US Inc (TMUS) Valuation

GoodMoat Analysis

Based on data as of March 26, 2026

The current price of $211.36 appears deeply undervalued relative to the GoodMoat Target of $601.71, implying a significant margin of safety of over 65%. While the P/E of 21.5x is above the sector average, it may be justified by T-Mobile's superior growth and profitability metrics.

Read full analysis
Based on the provided GoodMoat Target of $601.71, T-Mobile's current price of $211.36 represents a substantial discount, offering a margin of safety of approximately 65%. According to the GoodMoat framework's DCF bands, a margin of safety greater than 40% is considered 'Deeply Undervalued,' placing TMUS firmly in that category from this perspective. This is the most compelling valuation signal in the data. The forward P/E of 21.5x, while above a typical sector average for telecoms, must be evaluated in the context of the company's quality. An 11.3% YoY revenue growth rate and an 18.6% ROE, which exceeds the 15-20% high-quality threshold, suggest this is not a stagnant utility. The 8.5% Free Cash Flow Yield is also a strong positive indicator, providing a solid foundation for the DCF model. However, a value investor must reconcile this apparent deep value with the company's 2.0 Debt/Equity ratio, which is a point of caution, and the sector's generally slower growth profile. The valuation case hinges heavily on the credibility of the long-term cash flow projections embedded in the $601.71 target. If those growth and margin assumptions are reasonable, the current price offers a very favourable risk/reward profile.
