When does T-Mobile US, Inc. (TMUS) report earnings? On Oct 28, 2026, after the close

Of its last 12 earnings announcements: 6 after the close and 6 before the open. Each one comes from the 8-K with item 2.02 that T-Mobile US filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 65 quarters since Aug 5, 2010, and every row links to its filing.

Next announced date: Oct 28, 2026, after the close. It comes from the company through the public Nasdaq calendar, not from the SEC: it is a scheduled date and companies do move it. Everything else on this page already happened, with its filing attached.

TMUS window: when it reported after the close, from that day's close to the next; when it reported before the open or during market hours, from the previous close to that day's. Split-adjusted closes and EPS with its estimate, from Yahoo Finance. It already happened: it does not anticipate the next announcement.

Where each number comes from

From the 8-K with item 2.02 ("Results of Operations and Financial Condition") that T-Mobile US filed on EDGAR, the SEC's public database; only those with their 10-Q or 10-K behind them count, so other 8-Ks with the same item (production figures, monthly sales) stay out. The time is converted to New York time using this specific company's stamp convention (its EDGAR stamp arrives in UTC), and it is not assumed: it is derived from the hours in which EDGAR accepts filings. In 5 of this company's 65 quarters the date comes from the EDGAR acceptance day rather than the 8-K cover box, and those are flagged with an asterisk in the table.

What this data does not know

• The exact time of the press release: the 8-K reaches EDGAR minutes or hours later, so T-Mobile US's median 11:50 is an upper bound. The session says which one the news landed in, not what minute it was said.
• Nothing before Aug 5, 2010: it is T-Mobile US's oldest quarter with announcement and report paired in the file.
• What will happen. The page's only future date, Oct 28, 2026, was announced by T-Mobile US on the Nasdaq calendar and can be moved.
• T-Mobile US's identity is its SEC CIK (0001283699), not its symbol: symbols get recycled and renamed.
