Insights

Financial Analyst

TL;DR Insider sale of 37,418 shares at $304.05, corrected beneficial ownership increase of 3,393 shares.

The reported disposal is a concrete change in insider holdings: a sale of 37,418.163 shares on 09/02/2025 at $304.05 reduces direct holdings to 60,819.4431 shares. The filing separately discloses 13,813 shares held indirectly by a trust. The explanatory note clarifies a bookkeeping correction of +3,393 shares tied to a gift on 08/13/2025 that had been double-counted as a deduction. From a transactional standpoint, the Form 4 documents a completed sale and an administrative correction; it does not provide context on reason or use of proceeds.

Corporate Governance Expert

TL;DR Governance disclosure corrects prior miscount and reports a material insider sale; no allegation or inference offered.

The filing fulfills Section 16 reporting by identifying the reporting person as both director and officer and showing a timely disclosure signed by a POA. The corrective explanation improves record accuracy by adding 3,393 shares previously misreported. The sale is documented with price and date, meeting disclosure requirements. The Form 4 contains no indications of related-party transactions beyond the trust disclosure and provides no additional governance actions.
