NT 12b-25 (late filing notification)
When and how to file an NT 10-K or NT 10-Q to extend your deadline.
Rule 12b-25 lets you file a late-filing notification (NT 10-K or NT 10-Q) to get a 5-business-day extension on the 10-Q or a 15-day extension on the 10-K.
When to file it
You must file the NT before the original deadline. The system surfaces an amber alert in the Calendar module 5 business days before deadline if your 10-Q draft is not yet at "Ready to submit" status.
What you certify
You certify, under signature of an executive officer, that the late filing could not be filed without unreasonable effort or expense. You also describe the reasons (e.g., audit firm review still in progress, system upgrade, departure of the controller).
What it does for you
You get the extension automatically. You cannot get a second extension. If you miss the extended deadline, you go on the late-filer list and lose Form S-3 eligibility for 12 months.
What it does not do
It does not extend the audit. It does not extend the press release timing for earnings (those are governed by Reg FD and your bylaws, not 12b-25). It does not extend Section 16 filings.
After the NT
The system tracks the new deadline in the Calendar module. The original 10-Q draft remains open and resumes normal pre-flight checks against the new deadline.
