Understanding 8-K filings
In this guide, you'll learn what an 8-K filing is, when companies file one, and why it matters.
What Is an 8-K?
Form 8-K is a current report that publicly traded companies file with the U.S. Securities and Exchange Commission (SEC).
Its purpose is to disclose material events that could affect a company's business, operations, or investors. Because these events can happen at any time, 8-K filings are submitted on an as-needed basis rather than on a fixed schedule.
What Information Does an 8-K Include?
The contents of an 8-K depend on the event being reported.
Common disclosures include:
- Executive leadership changes
- Mergers and acquisitions
- Major contracts
- Bankruptcy proceedings
- Changes to financial results
- Significant legal matters
- Changes affecting shareholders
Each filing focuses on a specific event and may include supporting exhibits or additional documentation.
When Is an 8-K Filed?
Companies generally file an 8-K shortly after a reportable event occurs.
Because these filings are submitted throughout the year, they allow investors to stay informed without waiting for the next quarterly or annual report.
Why Is an 8-K Important?
An 8-K provides timely information about developments that may affect a company's future performance.
Investors often review 8-K filings to:
- Monitor important corporate announcements
- Stay informed about mergers and acquisitions
- Track executive leadership changes
- Review significant business agreements
- Understand events that could impact shareholders
Since the information comes directly from the company, the filing is considered one of the most reliable sources for major corporate updates.
How Is an 8-K Different From a 10-K or 10-Q?
Although all three are SEC filings, they serve different purposes.
- 10-K - Annual report with comprehensive financial information
- 10-Q - Quarterly update on financial performance
- 8-K - Reports significant corporate events as they occur
Many investors read all three filings to stay informed throughout the year. For a full comparison, read our 10-K vs. 10-Q vs. 8-K guide.
Where Can You Find 8-K Filings?
8-K filings are publicly available through the SEC's EDGAR database.
You can search using:
- Company name
- Stock ticker
- Central Index Key (CIK)
Most public companies also make recent SEC filings available through the investor relations section of their websites. For help searching EDGAR, read our SEC EDGAR database guide.
