In the United States, an 8-K is a form that companies must file with the Securities and Exchange Commission (SEC) to report significant events that may have an impact on their financial position or operations. The 8-K form must be filed within four business days of the occurrence of the event.

The events that trigger an 8-K filing can include things like changes in leadership, mergers and acquisitions, financial results, bankruptcies, and other material events that could affect the company's operations or financial condition. The purpose of the 8-K form is to provide transparency to investors and other stakeholders, ensuring that they are aware of important events as soon as possible.

The 8-K form typically contains information such as the date of the event, a description of the event, the impact of the event on the company's financial position, and any other relevant details. Investors and analysts often monitor 8-K filings to stay up-to-date on important events that could impact the companies they follow.

An 8-K is a regulatory filing required by the U.S. Securities and Exchange Commission (SEC) for publicly traded companies. It is used to notify investors of significant corporate events that could impact a company's financial position or operations. Often referred to as a "current report," the 8-K must be filed promptly, usually within four business days of the event.

Common events triggering an 8-K include mergers, acquisitions, bankruptcies, leadership changes, amendments to governance documents, or major legal proceedings. This filing provides transparency and ensures all stakeholders have access to timely, critical information. Investors often review 8-Ks to stay informed about developments that may influence a company’s stock performance or strategic direction.
