What is a Form 8-K, and what do its item numbers mean?

Form 8-K exists because annual and quarterly reports arrive too slowly for some news. When something specific and material happens between those reports, the company reports it on Form 8-K, the “current report”. The SEC’s form lists the events that require a filing and assigns each one an item number, so the header of every 8-K tells you, before you read a word of the document, what kind of event is being disclosed.

How quickly does a company have to file?

General Instruction B.1 of Form 8-K sets the default: the report is due within four business days after the triggering event. If the event happens on a weekend or holiday, the clock starts on the next business day. A few items work differently. Item 2.02 (results of operations) is triggered by the public announcement of earnings, and Item 7.01 can be used to satisfy Regulation FD when a company shares material information publicly. Item 1.05 (cybersecurity incidents) runs four business days from the date the company determines the incident is material, not from the date of the attack.

What do the item numbers mean?

Items are grouped into sections. The table below lists the items you will actually see on large-company filings, with the official title shortened to plain English.

Item	What happened
1.01	The company signed a material agreement outside the ordinary course of business
1.02	A material agreement was terminated
1.03	Bankruptcy or receivership
1.05	A cybersecurity incident the company has determined is material
2.01	An acquisition or sale of a significant amount of assets was completed
2.02	Results of operations: usually the quarterly earnings release
2.03	The company took on a material direct financial obligation, such as new notes or a loan
2.04	An event accelerated or increased a financial obligation
2.05	Costs of exit or disposal activities, such as restructuring or layoffs
2.06	Material impairment of assets
3.01	A delisting notice, a failure to meet a listing standard, or a transfer of listing
3.02	Unregistered sales of equity securities
3.03	Material modification of shareholders’ rights
4.01	Change of the company’s independent auditor
4.02	Previously issued financial statements should no longer be relied upon
5.01	Change in control of the company
5.02	Directors or certain officers departed, were elected or appointed, or their pay arrangements changed
5.03	Charter or bylaw amendments, or a change in fiscal year
5.07	Results of a shareholder vote
7.01	Regulation FD disclosure
8.01	Other events the company chooses to report
9.01	Financial statements and exhibits attached to the report

Item 9.01 almost always appears alongside another item because it covers the exhibits, such as an earnings press release filed as Exhibit 99.1. A filing tagged only “2.02, 9.01” is the ordinary pattern for a quarterly results release. The docket on our home page decodes these numbers for every filing automatically.

Which items deserve the closest reading?

Some items are routine for large companies; others are rare and usually significant. Items 2.02, 5.07 and 9.01 appear every quarter or every year for almost every issuer. Items 4.02 (non-reliance on past financial statements), 1.03 (bankruptcy), 3.01 (listing problems) and 4.01 (auditor change) are uncommon, and when they appear, the details in the body of the filing matter. Item 4.02 in particular means the company or its auditor has concluded that earlier financial statements contain an error serious enough that they should not be relied on.

Item 5.02 is broad. It covers a chief executive’s resignation, but also the appointment of a new director or an amendment to an officer’s compensation plan. Read the narrative to see which of these it is.

Filed versus furnished

General Instruction B.2 says information reported under Item 2.02 or Item 7.01 is “furnished” rather than “filed”. In practice this means it is not subject to Section 18 of the Exchange Act and is not automatically incorporated into the company’s securities registration statements, unless the company expressly states otherwise. Everything else on the form is filed. This distinction matters to lawyers more than readers, but it explains why earnings releases sometimes carry language saying the information “shall not be deemed filed”.

How do you read one efficiently?

Start with the item list on the cover page, then read the short narrative under each item. The exhibits listed under Item 9.01 often hold the substance, such as the full earnings release or the text of a new credit agreement. The SEC’s investor bulletin on reading an 8-K recommends checking the date of the event against the filing date and looking for any related later amendment (filed as an 8-K/A). Our guide on how to read an 8-K walks through a real example step by step.
