How soon after quarter-end must a company file a 10-Q?

The deadlines by filer category

The SEC sets 10-Q deadlines based on a company's "filer status," which is driven largely by its public float (the market value of shares held by non-affiliates). Large accelerated filers (generally $700 million or more in public float) and accelerated filers ($75 million to $700 million) must file within 40 days after the quarter ends. Non-accelerated filers and smaller reporting companies (below the accelerated threshold) get 45 days.

Annual 10-K deadlines follow a similar tiered structure but are longer: 60, 75, or 90 days respectively.

Filing versus announcing earnings

Note the difference between an earnings announcement and the 10-Q. Many companies issue an earnings press release (via an 8-K under Item 2.02) within a few weeks of quarter-end, well before the formal 10-Q. The press release contains preliminary numbers; the 10-Q that follows contains the complete, reviewed financial statements and footnotes. So a stock can move on the earnings release days or weeks before the official 10-Q lands.

When deadlines slip

If a company cannot meet its deadline, it can file a Form 12b-25 (Notification of Late Filing), which grants a short automatic extension (five calendar days for a 10-Q). A late filing — or repeated late filings — can itself be a warning sign, sometimes indicating accounting problems, an unresolved audit issue, or internal control weaknesses worth investigating.
