Source: collected SEC Form 4 records and Form 144 notices via EDGAR. This site matches Form 144 seller names exactly to the collected Form 4 filed name; a name match alone does not establish identity. Form 4 transaction value uses reported shares and price and is blank for zero or missing prices. That does not establish an award’s economic value. Records may be incomplete; a sale alone does not establish motive. SEC guide to insider reports.
