Insights

Financial Analyst

TL;DR: Routine insider sale of 116 shares by a director; small absolute size and limited apparent market impact.

The reported sale on 08/19/2025 of 116 shares at $59.02 reduces the director's stake to 7,458 shares. The filing provides exact trade date, price and post-transaction beneficial ownership, enabling straightforward disclosure analysis. There is no information in the Form 4 about the reason for the sale or any changes to trading plans beyond the checked box indicating a Rule 10b5-1 plan may apply.

Corporate Governance Expert

TL;DR: Filing meets Section 16 reporting requirements; the disclosure supports transparency but gives no governance signal.

The Form 4 is properly executed and discloses a director-level disposition. It documents compliance with reporting rules and identifies an attorney-in-fact signature. The form does not state any change in board role, nor any material event affecting governance. Without additional context on timing or proportionate holdings, the transaction appears routine.
