Form NT 10-K (notification of late filing)

Form NT 10-K is the notification of late filing, made on Form 12b-25, that a company submits when it cannot file its annual report on Form 10-K by the deadline. The equivalent for quarterly reports is the NT 10-Q.

How it works

The notice must be filed no later than one business day after the original due date. It explains why the report cannot be filed without unreasonable effort or expense. If the company then files the 10-K within 15 calendar days of the original deadline (5 calendar days for a 10-Q), the report is treated as timely, which preserves eligibility for short-form registration on Form S-3.

The form also asks whether the company expects significant changes in results from the prior year that will be reflected in the report, and if so, to describe them. Missing the extended deadline makes the company a late filer, which typically draws a deficiency notice from its exchange.

Why it matters for traders

Many NT filings are benign: a delayed audit for a small company, an acquisition that complicated year-end work, or an auditor transition. But a late filing can also be the first visible sign of serious trouble. Red flags include:

• Explanations involving an audit committee investigation, revenue recognition questions, or internal control problems.
• An auditor resignation or change shortly before the deadline.
• Language suggesting a restatement of prior periods.
• Uncertainty about the company's ability to continue as a going concern.
• A second consecutive NT filing.

Read Part IV of the form, where the company states whether it expects significant changes in results.

Example

A hypothetical medical device company, Bellwether Medical (BWMD), has a 10-K due March 16. On March 17 it files an NT 10-K citing an ongoing audit committee review of distributor revenue. The stock falls 22% that day. When BWMD misses the extended deadline of March 31, Nasdaq sends a deficiency notice, disclosed under 8-K Item 3.01.

FAQ

How long is the extension from an NT 10-K?

15 calendar days for a 10-K and 5 calendar days for a 10-Q, from the original due date.

Is a late filing notice always bad news?

No. Many are administrative. The stated reason, and whether it mentions investigations or restatements, matters most.
