What are 8-K filings

Form 8-K is a required SEC filing that gives investors timely disclosure of material events that could affect investment decisions. Companies must file it promptly (usually within 4 business days) after a significant event, instead of waiting for quarterly or annual reports.

What Form 8-K typically discloses (by category):

  • Major contracts: entering into, amending, or terminating material agreements.
  • Financial distress: bankruptcy, receivership, defaults, accelerated debt, or off-balance-sheet obligations.
  • Big transactions: acquisitions, mergers, asset sales, or restructuring/exit plans.
  • Financial results: earnings announcements and summaries of operating performance.
  • Accounting issues: asset impairments, auditor changes, unreliable past financial statements, and restatements.
  • Listing status: delisting notices or failure to meet exchange requirements.
  • Capital changes: private sales of securities and changes to shareholder rights.
  • Corporate control & governance: changes in control, directors or top executives, compensation changes, bylaws, fiscal year, or ethics code waivers.
  • Shareholder votes: results of annual or special meetings.
  • Fair disclosure (Reg FD): public release of material information to prevent selective disclosure.
  • Other material events: not covered elsewhere.
  • Supporting documents: financial statements and exhibits related to disclosed events.

Bottom line:

Form 8-K alerts investors quickly to material corporate events and red flags that could impact a company’s value.
