SEC 8-K filings, explained
Each material 8-K filed by an S&P 1500 company, read and summarized: what happened, the key numbers, whether it reads positive or negative for shareholders, and how big a deal it is (impact 1-5). This page lists the last 45 days; every brief stays on its company's 8-K page (1506 companies, A–Z).
23,605 AI briefs of 8-K filings on record, from 1,506 companies. Browse every brief by month, with filters →
0 of 2,273 briefs in the last 45 days.
Briefs are written by AI from the filing text and can contain mistakes — open the filing before acting on anything. Impact (1-5) and tone are the AI's reading of the filing for shareholders, not a price forecast. Not investment advice.
Frequently asked questions
Which filings get a brief?
Form 8-K filings by S&P 500, MidCap 400 and SmallCap 600 companies that report a material event: results (Item 2.02), deals (1.01, 2.01), executive changes (5.02), restructuring (2.05), impairments (2.06), delisting notices (3.01), restatements (4.02), cybersecurity incidents (1.05), bankruptcy (1.03) and Regulation FD or other events (7.01, 8.01). Routine filings such as vote results or exhibits only are skipped.
How is the impact score set?
The AI rates each filing from 1 (routine) to 5 (major, such as a merger, bankruptcy or restatement) based only on what the filing says. It is a reading aid for sorting the day's filings, not a prediction of how the stock will move.
How quickly do briefs appear?
The SEC filing feed is checked every hour on weekdays between 6 am and 10 pm Eastern; briefs follow within that hour or, when many filings arrive at once, later the same day.
Are older briefs kept?
Yes. This page shows the last 45 days, but every brief ever published stays online: each has its own page, and each company has an 8-K page listing all of its briefs, newest first, linked from its stock page and from the A-Z list of companies.
