Insights

Financial Analyst

TL;DR: Routine insider sale of 25,000 shares; reporting person still holds substantial direct and indirect stake.

The sale of 25,000 shares at a weighted average of $83.83 is a clear, single-date disposition recorded on Form 4. This transaction appears to be a disposition rather than an option exercise or derivative-related action. The post-sale direct beneficial ownership reported (1,287,803.0034 shares) plus indirect holdings (spouse, daughter, family partnership) indicate continued significant exposure to AGO equity. The inclusion of 253 ESPP shares purchased on 06/30/2025 is a clerical detail that confirms recent participation in employee programs. Overall, the filing documents a standard Section 16 transaction without additional context on intent or programmatic sales.

Corporate Governance Expert
