NT 10-K (Notification of Late Filing)

An NT 10-K is a form a company files with the SEC when it can't meet the deadline to submit its annual 10-K report (the detailed yearly financial statement all public companies must file). Think of it as a "we need more time" notice. You'll see these pop up when companies hit unexpected delays—accounting issues, audits taking longer than planned, or other complications. It's not a red flag by itself, but it's worth noting because it means you won't get the full financial picture on schedule. For example, if TechCorp Inc. couldn't finish its audit by the deadline, it might file an NT 10-K asking for an extra 15 days to complete and submit the actual 10-K.
