When does Martin Marietta Materials, Inc. (MLM) report earnings? On Nov 3, 2026

Of its last 12 earnings announcements: 12 before the open. Each one comes from the 8-K with item 2.02 that Martin Marietta Materials filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 65 quarters since Aug 3, 2010, and every row links to its filing.

Next announced date: Nov 3, 2026, with no time announced. 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.

Where each number comes from

From the 8-K with item 2.02 ("Results of Operations and Financial Condition") that Martin Marietta Materials 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 was read off the filing's official header. In 1 of this company's 65 quarters the date comes from the EDGAR acceptance day rather than the 8-K cover box, and it is 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 Martin Marietta Materials's median 07:02 is an upper bound. The session says which one the news landed in, not what minute it was said.
• Nothing before Aug 3, 2010: it is Martin Marietta Materials's oldest quarter with announcement and report paired in the file.
• What will happen. The page's only future date, Nov 3, 2026, was announced by Martin Marietta Materials on the Nasdaq calendar and can be moved. Martin Marietta Materials reporting before the open 25 quarters in a row does not say the next one will be the same.
• Martin Marietta Materials's identity is its SEC CIK (0000916076), not its symbol: symbols get recycled and renamed.
