Insights

Securities Analyst

TL;DR: Routine insider sales disclosed; total of 2,000 shares sold at roughly $91.94–$91.98, modest in isolation.

The Form 4 shows two contemporaneous sales by Director John B. Hansen totaling 2,000 shares executed on 08/12/2025 at reported prices of $91.975 and $91.94. Post-transaction holdings are reported as 92,664 shares direct and 15,000 shares indirect via a family trust. From a disclosure standpoint, the filing meets Section 16 reporting requirements; the amounts reported are quantitative facts in the record.

Corporate Governance Expert

TL;DR: Compliance-focused disclosure with clear indirect ownership noted; not a material corporate governance event.

The filing identifies the reporting person as a director and documents both direct and indirect beneficial ownership, explicitly noting the indirect stake is held by a trust benefiting his wife and children. This clarity supports transparency around related-party ownership. The transactions are sales rather than derivative activity, and the report contains the key ownership figures required for investor oversight.
