Context

The "exercise/conversion" (code M) entries reflect RSU vesting/settlement (not an option purchase); a portion of the vested shares were immediately sold to cover required taxes (a common administrative step). Such sell-to-cover transactions typically reflect tax obligations rather than a deliberate market disposition by the insider.
