What Is Form 8-K?

Form 8-K is a current report that publicly traded companies must file with the SEC to announce significant events that may be important to shareholders or the investing public. Unlike the periodic 10-K and 10-Q reports, 8-K filings are event-driven and must generally be filed within four business days of the triggering event. Reportable events include changes in control, acquisitions or dispositions of assets, bankruptcy or receivership, changes in the company's certifying accountant, material impairments, departure of directors or principal officers, amendments to articles of incorporation, and results of shareholder votes. The 8-K ensures that material information reaches the market promptly, supporting fair and transparent trading.

Form 8-K Example

  • 1When Microsoft announced its $69 billion acquisition of Activision Blizzard, both companies filed 8-K reports with the SEC detailing the terms of the deal.
  • 2A pharmaceutical company filed an 8-K within hours of its CEO's unexpected resignation, causing the stock to drop 8% in after-hours trading.
