Insights

Compensation & Equity Plan Analyst

TL;DR: Settlement of RSUs and achievement of PSUs increased holdings while customary tax-withholding shares were disposed.

The Form 4 shows routine equity compensation activity: grant-related RSUs (15,173 RSUs) were recorded and a PSU determination converted to 10,169 shares on 08/21/2025, reflecting the Compensation Committee's certification of performance metrics for awards granted 08/21/2024. The subsequent withholding disposition of 11,666 shares at $117.43 reflects standard tax-remittance procedures rather than an opportunistic sale. Overall beneficial ownership remains material at 135,913 shares, consistent with executive compensation settlement practices.
