Insights

Equity compensation analyst

Routine RSU vesting with share withholding for taxes; no open-market trading.

Michele Lau exercised 724 RSUs into common stock and had 285 shares withheld at $766.50 per share to satisfy tax obligations. This follows a standard RSU vesting schedule, with remaining RSUs vesting through May 21, 2027.

The transactions do not involve open-market buys or sells, so they mainly reflect compensation mechanics rather than a change in market view. Lau’s direct holdings rise to 6,797 shares, with additional indirect ownership through the company’s 401(k) plan and 725 RSUs still outstanding.
