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.
