Context This was a routine equity award vesting (PSUs), not an open-market purchase or sale. The $0.00 per-share entries reflect issuance and withholding mechanics for equity awards rather than an executed market trade. Shares withheld to cover taxes are common and should not be read as a discretionary sale signal.
