Insights

Financial Analyst

TL;DR: CFO purchased 200 shares at $71.38; modest insider buy with remaining unvested awards and tax-withholding reduced shares.

The transactions show the Chief Financial Officer participated in the company Purchase Plan by acquiring 200 shares at a closing-price-based price of $71.38 on 09/02/2025 and receiving an additional 200 Purchase Plan shares recorded at $0.00. Subsequent withholding of 144 shares on 09/03/2025 satisfied tax obligations tied to vested restricted stock units. Beneficial ownership after activity is reported as 14,321 shares.
