Insights

Securities Analyst

TL;DR: Insider sold 4,000 shares under a pre-existing 10b5-1 plan; transactions appear routine and disclosed properly.

The Form 4 discloses two discrete sale blocks totaling 4,000 shares executed on 09/02/2025 at weighted average prices of $63.619 and $64.617. The seller used a 10b5-1 plan adopted May 22, 2024, which typically signals preplanned disposition rather than opportunistic trading. Post-sale beneficial ownership is reported in the high tens of thousands, and the filing includes holdings through the ESPP and 401(k). For investors, this is a transparent, rule-compliant insider sale, without additional company-level financial data in the filing to assess broader impact.

Corporate Governance Expert

TL;DR: Filing follows Section 16 disclosure norms; use of 10b5-1 plan and attorney-in-fact signature are documented.

The report clearly checks the 10b5-1 box and includes explanatory footnotes about weighted average pricing and plan adoption date, which aligns with best-practice disclosure. The signature executed by an attorney-in-fact on 09/04/2025 is noted. There is no indication in the filing of amendments or other governance events. The disclosure is complete for the transactions reported and provides to the issuer and SEC a willingness to disclose per-footnote price breakdowns on request.
