Each Form 144 notice of a planned sale, grouped by broker and 10b5-1 plan, with the Form 4 sales we matched to it.
A Form 144 is a notice of a planned sale by an affiliate. SEC Tracker matches each notice to Form 4 sales by the same person at the same company within 90 days of the notice, up to the shares noticed. The match is our inference, not something either filing states.
No Form 144 notices with structured data (filed on EDGAR since April 2023).
| Notice date | Noticed | Planned sale | Outcome | Links |
|---|---|---|---|---|
| Sales without a matching Form 144 · 34 sales No matching Form 144 found. Not every sale needs one: small sales and sales by people who are not affiliates are exempt. | ||||

Every figure is as filed with the SEC on Forms 3, 4, 5 and 144. Holdings are the amounts reported after each person's latest filing at each company and can be out of date. Matching a Form 144 notice to Form 4 sales is SEC Tracker's inference from owner, company, dates and share counts, not something the filings state. Not investment advice.
