What is an NT filing (Form 12b-25)?
An NT filing (Form 12b-25), shown as “NT 10-K” or “NT 10-Q”, is a notice that a company will miss a report’s deadline — a recognized red flag.
The "we're going to be late" notice
An NT filing is a notice that a company will miss the deadline for a required report. NT stands for notification, and the form behind it is Form 12b-25. You'll see it in the feed as NT 10-K (a late annual report) or NT 10-Q (a late quarterly report).
What it means
By filing a 12b-25, a company formally tells the SEC it can't file on time and explains why. Doing so buys a short grace period — if the late report follows within five days (for a 10-Q) or fifteen days (for a 10-K), it's still treated as timely.
Why it's a red flag
A late filing often signals something is wrong behind the scenes: an unresolved accounting issue, an auditor dispute, a restatement in progress, or internal turmoil. It's not automatically disastrous, but it's worth paying attention to — repeated or unexplained NT filings are a warning sign.

NT filings carry a distinct badge in the live feed, and the filing detail page explains that no financial statements are included — the actual report comes later, when the company files it. Related: filing amendments.
