Form 8-K (Current Report) 8-K
An 8-K is the filing US companies use to disclose major events to the SEC promptly, between scheduled quarterly and annual reports.
What it is
Form 8-K is the 'current report' a US public company files to announce material events that shareholders should know about quickly. Triggers include earnings releases, executive changes, mergers and acquisitions, bankruptcies, auditor changes, and material agreements. It is the real-time channel of corporate disclosure, separate from the periodic 10-Q and 10-K.
Why it matters
The 8-K is where market-moving news first appears in an official filing, so it is a key feed for investors tracking events as they happen. Each 8-K is tagged with numbered 'items' that identify the type of event, which helps gauge severity quickly. A pitfall is treating every 8-K as urgent; many are routine, while items like 4.01 (auditor change) or 4.02 (non-reliance on prior statements) can be serious red flags.
How it's calculated
Not a calculated metric; it is an event-driven regulatory filing. It is generally due within four business days of the triggering event.
