Context

• These transactions reflect award vesting and routine tax withholding rather than an open-market purchase or a voluntary sale for investment purposes. The conversion/exercise at $0.00 and the footnotes indicate dividend-equivalent conversion and RSU vesting; the share disposition represents withholding to cover taxes (not necessarily a market sale for investment).
