Context

These entries reflect routine RSU vesting and subsequent transactions: shares were issued upon vesting (conversion of RSUs) and the issuer withheld/sold shares to cover taxes, while Stockdale sold additional shares in the open market. Such vesting and withholding are common compensation events and do not, by themselves, indicate a change in insider confidence.
