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.

How Quintarthai uses it

Material events and earnings releases reported on Form 8-K inform the news and event context Quinn considers, and every Quinn figure carries a click-to-source provenance receipt. Open a company page to review the analysis.

Cross-border note. The 8-K is a US filing; in Canada, comparable timely disclosure is made via a Material Change Report on SEDAR+, typically required within ten days of a material change.

FAQ

How fast must an 8-K be filed?
Generally within four business days of the triggering event, which makes the 8-K the most timely of the core SEC reports.
Do companies report quarterly earnings on an 8-K?
Yes. The earnings press release is usually furnished under Item 2.02 of an 8-K, while the full audited or reviewed statements appear later in the 10-K or 10-Q.
