That's incorrect. Any material event must be disclosed within 4 days. See SEC rules about 8-K:

In addition to filing annual reports on Form 10-K and quarterly reports on Form 10-Q, public companies must report certain material corporate events on a more current basis. Form 8-K is the “current report” companies must file with the SEC to announce major events that shareholders should know about.

Companies have four business days to file a Form 8-K for the events specified in the items in Sections 1-6 and 9 above. However, if the issuer is furnishing a Form 8-K solely to satisfy its obligations under Regulation FD, then the due date might be earlier.
