Source: SEC Form 4 and Form 144 filings, via EDGAR. Form 144 carries no filer identifier, so those notices are matched to this page by name alone. Value is shares times the reported price, and is blank where the filing priced the transaction at zero — a grant costs its recipient nothing. Insiders sell for reasons that have nothing to do with the company, which is why a sale is not read as a signal on its own.
