Insights

Financial Analyst

TL;DR: Insider sales on 09/25/2025 reduced direct holdings modestly; total economic exposure remains sizable due to DSUs and 401(k) holdings.

The reported brokered sales of 4,974 shares (at $131.77–$132.76) and 26 shares (at $132.80) represent a partial disposition of the reporting officer's direct position. Despite the sales, the reporting person retains material ownership: 90,713 direct shares plus 28,604 deferred stock units that convert one-for-one, and 14,053 shares in a 401(k). From an analytical perspective, this is a routine liquidity event rather than a clear signal of changing confidence, since significant equity-linked holdings remain.

Corporate Governance Expert

TL;DR: Filings comply with Section 16 disclosure; sales were reported promptly and include dividend reinvestment details.

The Form 4 discloses prompt reporting of open-market sales and provides explanatory notes about dividend reinvestment and the composition of deferred stock units. The filing includes granular disclosure that 17 shares and 300 DSUs were acquired through dividend reinvestment since the last filing, and 147 401(k) shares were purchased via reinvested dividends. The transparency around reinvestment activity and DSU settlement terms (one-for-one) supports good governance and clear beneficial ownership tracing.
