Context
This was primarily a vesting/award event (not an open-market purchase). The shares withheld/sold were routine tax-withholding transactions tied to vesting (common practice) rather than discretionary market sales. The derivative line reflects conversion/settlement activity tied to the awards and does not indicate a separate cash purchase.
