Key Details

• Transaction date: 2026-03-05; Filing date (Form 4): 2026-03-09 (timely within required reporting window).
• Award: 38,002 shares (reported as 19,001 time-based RSUs + 19,001 performance-based RSUs at target).
• Withholding sale: 1,182 shares sold at $76.31 → ~$90,198 to cover tax liability.
• Shares owned after the transactions: not specified in the supplied excerpt of the filing.
• Footnote: PSUs cliff-vest after a three-year performance period and can pay out from 0% to 200% of the target based on actual performance; time-based RSUs vest in equal installments over three years.
• Transaction codes: A = Award/Grant; F = Payment of exercise price or tax liability (share withholding).

Context

• This is a standard equity compensation grant with mandatory share withholding to cover taxes — common for RSU/PSU awards and not an open-market sale indicating a change in investment stance.
• The PSU component is performance-contingent; the ultimate number of shares earned from that portion could be higher or lower than the target award depending on performance at vesting.
