Most company news reaches the public through a form almost nobody reads directly. It is the 8-K. Companies file it when something material happens between quarterly reports. The press release you see quoted in a headline is usually an exhibit attached to that filing.
The 8-K is a good form to learn because it is structured. Every 8-K is organized by numbered items. The item number tells you the category of event before you read a single sentence of prose. Once you know which numbers carry information and which are housekeeping, you can triage a day of filings quickly.
This article explains the mechanics. It is not investment advice.
What an 8-K actually is
The 8-K is the current report. The 10-Q and 10-K are periodic. They arrive on a schedule. The 8-K arrives when an event triggers it.
The general deadline is four business days after the triggering event. There are exceptions. Some items have their own timing rules, and a Regulation FD disclosure has to go out on a schedule tied to the underlying disclosure rather than the four day window. The official list of every item, with the exact language for each trigger, is in the form itself on sec.gov.
Four business days is fast. That is worth holding in your head as a contrast with other disclosure regimes. Congressional stock trades run on a much slower clock, which we cover in the 45-day rule and why it matters. Institutional holdings run slower still, as explained in 13F deadlines and the 45-day lag. The 8-K is the fastest of the three by a wide margin.
The item number is the first thing to read
Open any 8-K and you will see a header block, then one or more item numbers with titles. Everything after that is the disclosure.
The numbering is grouped by theme. The 1.x items cover contracts and business agreements. The 2.x items cover financial results and obligations. The 3.x items cover securities and listing status. The 4.x items cover accountants and financial statement reliability. The 5.x items cover governance and management. The 7.x item is Regulation FD. The 8.x item is everything else. The 9.x item is the exhibit list.
A single 8-K can carry several items at once. An earnings release is usually Item 2.02 plus Item 9.01, because the press release itself is attached as Exhibit 99.1.
The items that usually carry information
Item 1.01, Entry into a Material Definitive Agreement. This is the contract item. Acquisitions, credit facilities, licensing deals, major supply agreements, and settlements all land here. The word "material" is doing real work. The company has decided this agreement matters enough to disclose outside the normal reporting cycle. Read the counterparty, the size, and the term. Then check Item 9.01 to see whether the actual agreement was filed as an exhibit, because the exhibit usually contains terms the summary skips.
Item 2.02, Results of Operations and Financial Condition. Earnings. This is the highest volume meaningful item because every reporting company files it four times a year. The 8-K body is often two sentences pointing at the attached press release. The information is in Exhibit 99.1, not in the item text.
Item 5.02, Departure of Directors or Certain Officers. Executive changes. This item has sub-parts and they are not equivalent. A CFO resignation reads very differently from a routine board appointment. The sub-part that gets the most attention is the one covering a director who resigns because of a disagreement with the company. Companies are required to describe the disagreement when that is the reason. That is rare and it is specific. Most 5.02 filings are ordinary succession, retirement, or a new compensation arrangement for an existing officer.
Item 8.01, Other Events. This is the catch-all, and that is exactly why it deserves attention. The company has decided to disclose something it considers worth telling the market, but the event does not fit a defined category. Buyback authorizations, litigation updates, clinical trial readouts, regulatory decisions, and operational disruptions often appear here. The item number tells you nothing about content. You have to read the text. An 8.01 is the one item where skimming the header is useless.
Four more that deserve a second look
Item 4.02, Non-Reliance on Previously Issued Financial Statements. This means prior financials cannot be trusted and will likely be restated. It is uncommon and it is serious.
Item 3.01, Notice of Delisting or Failure to Satisfy a Continued Listing Rule. The exchange has told the company it is out of compliance. Often this is a minimum price or minimum market value issue.
Item 1.05, Material Cybersecurity Incidents. A newer item covering material cybersecurity incidents, with its own timing tied to the materiality determination rather than the incident date.
Item 2.06, Material Impairments. A write-down the company concluded it has to take. This tells you an asset or a business line did not perform as expected.
The items that rarely move anything
Not every 8-K is news. Several items are compliance plumbing.
Item 5.07, Submission of Matters to a Vote of Security Holders. This is the annual meeting vote tally. The outcome is usually known in advance from the proxy.
Item 5.03, Amendments to Articles of Incorporation or Bylaws. Often a technical change, a state law update, or a fiscal year adjustment.
Item 5.05, Amendment to the Code of Ethics. Almost always administrative.
Item 9.01, Financial Statements and Exhibits. This is a list, not an event. It never appears alone in a way that means anything on its own.
Item 3.02, Unregistered Sales of Equity Securities. This one is genuinely mixed. For a large company it can be routine. For a small company it can signal dilution or a financing that changes the capital structure. Private placements often have a related Form D filed separately, and reading the two together gives you more than either alone. We walk through that form in how to read a Form D filing.
Filed versus furnished
This distinction confuses people and it is worth twenty seconds.
Items 2.02 and 7.01 are typically furnished rather than filed. Furnished information carries different liability treatment and is not automatically incorporated by reference into registration statements unless the company says so. The practical reading is that a company can put forward looking commentary in a furnished earnings release with a different legal posture than a filed disclosure. Check the cover page language. It will say explicitly whether the information is furnished.
A two minute reading routine
- Read the item numbers in the header. That is your category.
- Read the date of the triggering event, not just the filing date. A company can file on day four.
- Go straight to Item 9.01 and open Exhibit 99.1 if there is one. That is where earnings and most announcements actually live.
- For Item 1.01, look for the agreement exhibit and read the economic terms.
- For Item 5.02, identify the sub-part and the reason given.
- For Item 8.01, read the whole thing. There is no shortcut.
- Check whether the filing was amended later. An 8-K/A adds or corrects material.
Free ways to read 8-Ks yourself
You do not need a paid terminal for any of this. EDGAR full-text search at sec.gov/edgar/search lets you search the text of filings and filter by form type and date. The company browse page on EDGAR gives you a chronological filing history for any registrant. EDGAR also publishes daily and full index files, plus RSS feeds, so you can poll for new filings without scraping pages. Company investor relations pages usually mirror the same press releases.
Those primary sources are the ground truth. Anything a data product tells you should be traceable back to a filing you can open yourself. That principle applies across disclosure types, including legislative ones, which we cover in how congressional trading disclosures work.
The honest limitation
Knowing which item numbers matter tells you where to look. It does not tell you what a filing means for price. Markets often price an event before the 8-K posts, because a press release can hit the wire first and the filing follows. Two identical item numbers at two different companies can carry completely different weight. The item number is a filter, not a conclusion.
The useful habit is comparison over time. One 8-K is an anecdote. A pattern of 4.02 filings, repeated 5.02 departures in a single function, or a run of 3.01 notices tells you something a single document cannot.
If you want to see the same primary-source discipline applied to a different disclosure stream, our Congress Stock Trades report scores filed congressional transaction disclosures the same way, with every scored signal traceable back to the original filing you can open and verify yourself.
