Insights

Securities Analyst

Officer exercised vested options, sold the resulting shares at about $109–$110, and returned to zero holdings.

The filing documents two paired transactions on 08/08/2025 and 08/11/2025 in which 113,000 option-derived shares were acquired at the option exercise price of $22.5525 and then sold at weighted-average prices of $108.8916 and $110.2906. The stock options were exercisable since 05/21/2021 with expiration 05/21/2030. The filing discloses trade price ranges for the sales and shows the reporting person holding 0 shares after the transactions. These are typical executive option exercises followed by disposition to monetize gains.

Corporate Governance Expert

Transactions appear procedural: option exercises, immediate sales, and a POA-signed filing; disclosure is complete on prices and trade ranges.

The Form 4 includes both the derivative-side detail (exercise price, exercisable and expiration dates) and the non-derivative side (acquisitions and sales with weighted-average sale prices and post-transaction holdings). The signature is provided via a Power of Attorney (Lance E. D'Amico). The explanation lists trade price ranges, which supports transparency about execution. No amendment date or additional restrictions are disclosed in the form.
