# T-Mobile US: Competitors & Industry Structure

## Direct Answer

SEC EDGAR classifies T-Mobile US under SIC code 4812 (Radiotelephone Communications). Among Swoopr's S&P 500 Equal Weight companies, 3 others share that classification; by latest reported revenue, T-Mobile US ranks 1 of 4. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes.

## How Does T-Mobile US Compare With Its Peers?

| Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin |
| --- | --- | --- | --- | --- |
| **T-Mobile US (TMUS)** | $88.3 billion FY2025 | 8.5% | 20.7% | 12.4% |
| [Array Digital Infrastructure Inc. (AD)](https://www.getswoopr.com/stocks/companies/array-digital-infrastructure-inc/) | $163 million FY2025 | 58.3% | -56.8% | 42.5% |

Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care.

## Where These Numbers Come From

Every figure on this page is a value T-Mobile US reported in its own SEC filings, read from the SEC's XBRL data (accession 0001283699-26-000010 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.

Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
