| FCF margin | 19.0% |
| Gross margin | 47.0% |
| ROIC | 12.4% |
| Total Debt to Equity | 136.1% |
Investment Thesis
T-Mobile US stands out as a leading U.S. wireless carrier, leveraging its scale and innovative service offerings to drive consistent revenue growth. With a market cap of $236.0B and a robust free cash flow of $16.3B, T-Mobile’s 7.3% revenue growth and 19.0% FCF margin highlight its operational efficiency. The company’s quality rating of 6.9 (on ValueSense’s scale) underscores its strong fundamentals, though its intrinsic value $57.6 suggests the current market price may be above fair value.
T-Mobile’s 12.4% ROIC demonstrates effective capital allocation, while its gross margin of 47.0% supports healthy profitability. Despite a recent 1-year return of -5.2%, the company’s scale and network investments position it well for long-term growth, especially as 5G adoption accelerates.
Key Catalysts
- Continued 5G network expansion and subscriber growth
- Integration of new services and digital platforms
- Potential for margin improvement through operational efficiencies
Risk Factors
- High total debt to equity 136.1% may constrain future flexibility
- Competitive U.S. telecom landscape with aggressive pricing
- Sensitivity to regulatory changes and spectrum costs

| FCF margin | 16.0% |
| Gross margin | 47.0% |
| ROIC | 7.1% |
| Total Debt to Equity | 125.0% |
Investment Thesis
AT&T remains a telecom giant with a $177.1B market cap and a diversified service portfolio. The company’s 1-year return of 11.2% reflects recent operational improvements and strategic refocusing. AT&T’s $20.0B in free cash flow and a 16.0% FCF margin provide a solid foundation for ongoing investment and shareholder returns. Its quality rating of 6.2 and intrinsic value of $23.4 suggest the stock is trading near fair value.
AT&T’s revenue growth is modest at 2.0%, but its stable gross margin 47.0% and manageable ROIC 7.1% indicate steady performance. The company’s high debt to equity 125.0% remains a concern, but ongoing deleveraging efforts and a focus on core telecom operations could enhance future prospects.
Key Catalysts

| FCF margin | 10.0% |
| Gross margin | 52.7% |
| ROIC | 15.9% |
| Total Debt to Equity | 88.5% |
Investment Thesis
Verizon, with a $168.0B market cap, is a core player in the U.S. telecom landscape. The company’s 1-year return of -4.0% reflects recent market headwinds, but its $13.8B free cash flow and 52.7% gross margin demonstrate resilience. Verizon’s quality rating of 5.8 and intrinsic value of $104.1 highlight its solid fundamentals and potential undervaluation.
Verizon’s 2.4% revenue growth and 15.9% ROIC point to efficient operations, while a debt to equity ratio of 88.5% is lower than many peers. The company’s focus on network reliability and premium services positions it to benefit from ongoing 5G adoption.
Key Catalysts

Investment Thesis
Vodafone, a major European telecom operator, has a $31.0B market cap and a strong 1-year return of 33.4%. Despite a negative revenue growth rate -34.9%, the company’s €23.4B free cash flow and 39.4% FCF margin are notable. Vodafone’s quality rating is 5.5, and its intrinsic value of $62.3 suggests significant upside potential.
The company’s gross margin 32.3% and high FCF generation reflect operational strengths, but a negative ROIC -2.6% and ongoing restructuring efforts highlight challenges. Vodafone’s focus on asset sales and simplification could unlock value for shareholders.
Key Catalysts

With a gross margin of 100.0% (likely reflecting accounting treatment), Telefónica’s 3.7% ROIC and relatively low debt to equity 36.0% suggest prudent financial management. The company’s negative revenue growth -4.7% remains a concern, but its diversified geographic footprint offers resilience.
Key Catalysts
