What is an SEC 8-K filing?

What an 8-K is for

The 8-K exists to keep investors informed of material events on a timely basis, rather than waiting for the next scheduled 10-Q or 10-K. Because markets can move sharply on news, the SEC requires companies to disclose specific categories of events quickly and in a standardized format, so all investors learn about them at roughly the same time.

An 8-K is organized into numbered "Items," each corresponding to a type of event. The item number tells you at a glance what the filing is about — for example, Item 2.02 covers results of operations (earnings), Item 5.02 covers departures of directors or officers, and Item 1.01 covers entry into a material agreement.

Common 8-K items and timing

Frequently seen items include: Item 1.01 (material definitive agreement), Item 2.01 (completion of an acquisition or disposition), Item 2.02 (results of operations and financial condition), Item 5.02 (departure or appointment of directors and officers), Item 7.01 (Regulation FD disclosure), and Item 8.01 (other events, a catch-all).

The general deadline is four business days after the triggering event, though some items (such as certain Regulation FD disclosures) have different rules. Earnings-related 8-Ks often "furnish" rather than "file" the press release, a technical distinction that affects liability but not the information you can read.

How to read one quickly

Start with the item number and heading to understand the topic, then read the short narrative. Many 8-Ks attach exhibits — a press release (Exhibit 99.1), a material contract, or a separation agreement — where the substantive detail lives. For earnings, the attached press release usually contains the income statement and management commentary that move the stock.
