Poplawski Brice J 4

The RSUs converted on a one-for-one basis (no exercise price). On March 2, 2026, 158 of those shares were withheld to satisfy tax withholding obligations, valued at $126.09 per share for a total of $19,922.

• Conversion: 646 RSUs converted to 646 common shares (code M — derivative conversion); exercise price $0 (RSUs).
• Withholding: 158 shares withheld (code F) at $126.09/share = $19,922 to cover taxes.
• Shares owned after the transaction: not specified in this Form 4 filing.

• Filing timeliness: Report filed 2026-03-02 for a 2026-03-01 event (timely under Form 4 rules).

Context

• This was a routine vesting/conversion of RSUs rather than an open-market purchase or sale; the withholding of shares to meet tax obligations is common and is not an independent sale signal. The conversion involved no cash exercise price (RSUs), and withholding served as the tax payment mechanism (similar to a cashless settlement).
