Understanding 8-K Filings
What is an 8-K filing?
An 8-K is a current report. A public company files it with the SEC when a specific material event happens. The company does not wait for the end of a quarter. The SEC sets a deadline of 4 business days after the event for most items. The filing names the event with a numbered item code, describes what happened, and often attaches the press release as an exhibit. The 8-K becomes public on SEC EDGAR as soon as the company files it.
Educational Content: This page explains SEC filing rules and how to read a filing. It is not investment advice or a recommendation to buy or sell securities. All trading involves risk.
Why 8-K filings exist
Before the SEC required current reports, a company could hold a material event back or tell some investors first. The 8-K rule removes that gap. When a material event happens, every reader gets the same document at the same time.
You can read every 8-K a company has filed on its history page. For example, /8k/aapl/ lists Apple filings, and /8k/ lists all companies with 8-K coverage.
What triggers an 8-K
The SEC groups the trigger events into numbered sections. Each event has an item number.
| Section | Subject | Examples |
|---|---|---|
| 1 | Business and operations | Material agreements, termination of an agreement, bankruptcy, mine safety, cybersecurity incidents |
| 2 | Financial information | Completed acquisitions, earnings results, new debt, exit costs, asset impairments |
| 3 | Securities and trading markets | Delisting notices, unregistered stock sales, changes to shareholder rights |
| 4 | Accountants and financial statements | A change of auditor, a statement that past financials are unreliable |
| 5 | Corporate governance and management | Change of control, officer and director changes, bylaw amendments, shareholder votes |
| 6 | Asset-backed securities | Servicer changes, missed distributions |
| 7 | Regulation FD | Information the company gives to the public under Regulation FD |
| 8 | Other events | Any event the company chooses to disclose |
| 9 | Financial statements and exhibits | Statements for an acquired business, pro forma data, press releases |
The 8-K Event Types page lists every item number with its official SEC name.
The 4-business-day rule
Two exceptions apply to that deadline:
- Item 7.01 (Regulation FD Disclosure). The company must file at the same time as the public disclosure, or before it.
- Item 1.05 (Material Cybersecurity Incidents). The 4-day clock starts when the company decides the incident is material, not on the date of the incident.
A company that misses the deadline can file Form NT 8-K to report the delay.
How to read an 8-K
The header. The header gives the company name, the ticker, the filing date, the event date, and the item numbers. Compare the event date to the filing date. A large gap shows the company used most of the 4-day window.
The item numbers. Each number maps to one SEC event type. One 8-K can report several items. A filing that reports both Item 5.02 (an officer change) and Item 4.01 (an auditor change) describes two separate events on the same day.
The body. The body describes the parties, the financial terms, the effective date, and any conditions. Look for the actual numbers and for the word "contingent".
The exhibits. Exhibit 99.1 is usually the press release. Exhibit 99.2 is usually a slide deck. The exhibits often hold more detail than the body of the filing.
Materiality depends on size
A number in a filing means little on its own. Compare it to the company. A contract worth 180 million a year. The same contract barely changes a company that earns $50 billion. Open the financial statements for the company to get the revenue and the share count you need for that comparison.
How Profitelligence processes 8-K filings
- Monitor. The system polls the SEC EDGAR feeds continuously and finds new filings within minutes.
- Classify. A language model reads the filing, records the item numbers, extracts the dates and amounts, and writes a plain-English summary.
- Compare. Each filing page shows the price reaction after the filing and lists earlier filings of the same type by the same company.
- Alert. You can set alerts for the companies on your watchlist in the Alert Manager.
The filing pages report what happened and what happened before. They do not forecast a price.
Common questions
How fast do companies file? The deadline is 4 business days. Many companies file within 1 or 2 days. Companies often file earnings results on the same day they announce them.
Does every material event need an 8-K? No. Only the events in the SEC item list trigger an 8-K. A company reports other developments in its 10-Q or 10-K.
What is an 8-K/A? An 8-K/A amends an earlier 8-K. Some amendments correct a typo. Others add financial statements that the SEC allows the company to file later. Read the explanatory note at the top.
Are 8-K filings public right away? Yes. The filing appears on SEC EDGAR as soon as the company submits it.
