SEC Form 8-K Item 4.01: Changes in Registrant's Certifying Accountant

What this item covers, when public companies must file it, and the most recent real filings reporting it.

What Item 4.01 requires

A registrant filing under Item 4.01 of Form 8-K is reporting changes in registrant's certifying accountant. The 8-K is the "current report" that public companies use to disclose material events between quarterly filings; each item code targets a specific category of event.

Filers don't always classify events correctly: material cybersecurity incidents that should trigger Item 1.05 sometimes get filed under the catch-all Item 8.01, and material officer departures that should be 5.02 occasionally hide there too. Reading the body text — not just trusting the filer-reported item code — is how you catch buried news.
