CluenexT-Mobile US TMUS
T-Mobile US scores average on business quality (5.5 of 10). Here is why, in plain words, and what our sealed record shows.
Why it matters
- What T-Mobile US does
T-Mobile US sells wireless voice and data services to retail and business customers across the United States, generating revenue mainly through monthly subscription plans and device sales.
- What it does best
T-Mobile excels at network efficiency, driving a gross margin of 62.7% that ranks in the top quartile of its sector. This edge stems from its early nationwide mid-band spectrum deployment, which delivers superior 5G coverage that competitors struggle to match economically.
- The main risk
Carrying $92 billion in total debt creates a heavy structural drag, leaving the balance sheet vulnerable if interest rates stay elevated or cash generation stumbles.
Quality, check by check
Scored against its own industry, from company filings.
Operating margins hit 21.1% while free cash flow margins land in the sector's top quartile at 58%. Scale drives these gains as network deployment costs flatten against rising subscriber revenue.
Switching costs and network scale lock in consumers. Operating in the top quartile for sector margins, T-Mobile commands a 5G footprint that rivals require years of multi-billion-dollar capex to replicate.
Revenue grew 8.5% to $92.2 billion over the past year. This top-line expansion accelerates compared to historical flat periods, driven by subscriber gains in mobile and home internet.
Debt-to-equity sits high at 1.6 while interest coverage is modest at 4.8x. Free cash flow reached $16.2B, showing a massive jump that softens the balance-sheet weight.
