Insights

Corporate Insider/Compensation Analyst

CEO received vested PSUs; tax withholding reduced holdings by 4,118 shares.

The Form 4 shows 892 shares issued upon vesting of performance-based restricted stock units tied to performance criteria from awards dated March 15, 2025. These shares were not previously reportable because vesting depended on performance.

The issuer withheld 4,118 shares to cover tax withholding at a price of $310.38, moving the reporting person from 204,129 beneficial shares down to 200,011. This is a routine tax-withholding event following equity vesting and does not itself indicate a sale for cash proceeds.
