What it means
8-K
What is a Form 8-K?
A Form 8-K is an event-driven report filed under the Securities Exchange Act of 1934, not on a fixed schedule like the annual and quarterly reports. Companies use it to tell the market about specified developments between periodic reports. Foreign private issuers use a different form, Form 6-K.
Which events require an 8-K?
An 8-K is required when an event falls under one of the numbered items in the form. The table lists several items that communications teams meet often. It is a selection, not a complete list.
| Item | Subject | Typical trigger |
|---|---|---|
| 1.05 | Material cybersecurity incidents | The company determines an incident is material |
| 2.01 | Completion of an acquisition or disposition | A significant deal closes |
| 2.02 | Results of operations and financial condition | A public earnings announcement |
| 4.02 | Non-reliance on previously issued financial statements | The company or auditor concludes past statements cannot be relied on |
| 5.02 | Departure or appointment of certain directors and officers | A CEO, CFO or director change |
| 7.01 | Regulation FD disclosure | Information furnished to meet Regulation FD |
| 8.01 | Other events | Voluntary disclosure of other material information |
When is a Form 8-K due?
A Form 8-K is generally due within four business days after the event that triggers the requirement. Several items follow their own timing:
- Item 1.05: the four business days run from the company's determination that the incident is material, not from discovery. Securities Act Release 33-11216 added this item, effective September 5, 2023.
- Item 8.01: has no mandatory deadline, although prompt filing is encouraged.
- Weekends and holidays: business days exclude days the SEC is closed.
What is the difference between filed and furnished?
Information in an 8-K is either filed or furnished, and the difference affects legal liability. Items such as 2.02 and 7.01 are generally furnished, which means the information is not treated as filed for certain liability purposes unless the company says so. Most other items are filed. Counsel decides which treatment applies to each disclosure.
How do communications teams work with an 8-K?
The 8-K and the press release are coordinated tools: the filing meets the regulatory requirement, and the release shapes the story for media and investors. A typical working sequence is:
- Confirm with legal whether an event triggers an 8-K item and what the deadline is.
- Draft the filing text and the press release together so the facts match.
- Decide the release time and make sure disclosure reaches the market broadly, consistent with Regulation FD.
- Prepare internal messages, investor Q&A and media responses for the same moment.
- Keep a record of who approved the final text.
Earnings releases and calls need extra care. See earnings call for the planning side, and consult counsel on how Item 2.02 timing works with a scheduled call.

Why should the rules be rechecked?
Disclosure rules and SEC staff guidance change, and the examples above are a summary. The cybersecurity item is recent and has been the subject of SEC staff interpretations, including on timing and on ransomware payments. Check the current Form 8-K instructions and staff guidance on the SEC website, and confirm the position with securities counsel before relying on any summary.
Frequently asked questions
What does 8-K stand for?
The number is the form's designation in the SEC's EDGAR system. Its official name is Current Report Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934.
Is every press release filed on an 8-K?
No. Only information that falls under an 8-K item, or that a company chooses to disclose under Item 7.01 or 8.01, goes in a filing. Many routine releases are not filed.
Does a company need an 8-K to meet Regulation FD?
No. An 8-K under Item 7.01 is one method of broad public disclosure. Other methods can qualify, so the choice should be made with counsel.
What happens if a company misses the deadline?
Consequences can include SEC enforcement and loss of eligibility to use certain short-form registration statements. The details depend on the item and the facts.
Can a company amend an 8-K?
Yes. A company may file an amendment, form 8-K/A, when information was unavailable at the time of the original filing or needs correction.
