8-K events
Major news companies must report to the SEC: results, deals, leadership changes.
About this data
- What it is
- A Form 8-K is how a public company announces major news between its quarterly reports: earnings, an acquisition, a new CEO, a cybersecurity incident. Each filing lists the numbered items it covers.
- Who files it
- The company, usually within four business days of the event.
- How current
- We collect new filings throughout the day on SEC business days.
- Worth knowing
- Many 8-Ks are routine, so the item description is the place to start. Item 9.01, which only lists attached documents, is hidden unless you ask for it.
All of this comes from public filings.
