Insights

Securities compliance analyst

Routine RSU tax withholding; no open-market sale.

The transaction is coded F, meaning shares were withheld to satisfy taxes upon RSU vesting. This is a standard administrative action and does not reflect discretionary selling activity in the market.

The officer now holds 74,853 shares directly after withholding. Market impact is typically minimal because no shares were sold into the open market and the action stems from equity award mechanics.
