Companies file 8-Ks to report a wide range of material events. Common triggers include earnings releases, the entry into or termination of a major agreement, mergers and acquisitions, the departure or appointment of executives and directors, changes in the company's auditor, bankruptcy, and other significant corporate developments. Each 8-K identifies the specific item number corresponding to the type of event being reported.
Unlike the 10-K and 10-Q, the 8-K is not a comprehensive financial report and does not contain a full set of XBRL-tagged financial statements — though earnings information is often furnished as an exhibit. An 8-K is generally due within four business days of the triggering event, reflecting its role as a prompt-disclosure document.
Because 8-Ks surface material events in real time, they are an important complement to the periodic financial data GeminIQ sources from 10-K and 10-Q filings.
