What Is an SEC Form 8-K? The Filing That Reports Breaking Company News

Form 8-K is how US public companies announce material events within four business days: deals, executive departures, earnings, bankruptcies and cyber incidents. Here is how to read it and which items matter.

When a US-listed company has news that could move its stock, it does not wait for the next quarterly report. It files a Form 8-K, the "current report", with the SEC. It is the fastest official channel a company has, and it is free to read on EDGAR the moment it is filed.

If Form 4 tells you what insiders did, the 8-K tells you what the company says happened.

How fast is it filed?

In most cases a company must file an 8-K within four business days of the triggering event. Some disclosures are voluntary (companies use the form to share information they want on the record), but the list of mandatory events is long and specific.

The structure: items

An 8-K is organised into numbered items. The item number tells you what kind of news it is before you read a word. The ones you will see most:

• Item 1.01 - Entry into a material definitive agreement. A big contract, credit facility or merger agreement was signed.
• Item 1.03 - Bankruptcy or receivership.
• Item 2.01 - Completion of an acquisition or disposal of assets.
• Item 2.02 - Results of operations and financial condition. The earnings press release usually arrives attached to this item.
• Item 3.01 - Notice of delisting or failure to satisfy a listing rule.
• Item 4.02 - Non-reliance on previously issued financial statements. The company is telling you its past numbers should not be trusted. This one deserves attention.
• Item 5.02 - Departure or appointment of directors and certain officers. A CEO or CFO leaving shows up here.
• Item 5.07 - Results of a shareholder vote.
• Item 7.01 - Regulation FD disclosure. Investor presentations and similar material.
• Item 8.01 - Other events. A catch-all.
• Item 9.01 - Financial statements and exhibits. Where the attached documents are listed.

Since late 2023 there is also Item 1.05, material cybersecurity incidents, which is due four business days after the company determines the incident is material.

What is in the exhibits

The 8-K itself is often a page or two. The substance sits in the exhibits: the press release (Exhibit 99.1), the signed agreement (Exhibit 10.x) or the merger agreement (Exhibit 2.1). Always open them.

"Filed" versus "furnished"

Information under Items 2.02 and 7.01 is normally furnished, not filed. The practical difference is legal liability: furnished information is not subject to certain liability provisions of the Exchange Act. It does not change how you read the news, but it explains why you will see both words.

How to use it

1. Look at the item numbers first. A stack of 5.02 filings around a quarter-end is a different story from one 2.02.
2. Compare the timing with insider activity. An executive sale a few days before bad news is not proof of anything, but it is the kind of thing worth checking, and the pitfalls in reading insider data apply.
3. Read the exhibit, not the headline. Press releases are written to be read quickly. The agreement is written to be enforced.
4. Check for an amendment. An 8-K/A corrects or adds to an earlier filing.

Limits

An 8-K is the company's own account, written by its lawyers. It tells you what must be disclosed, not what is happening inside. Treat it as a primary source to be read critically, alongside the other public filings you can use to research a stock.
