Insights

TL;DR: Routine insider sale under a 10b5-1 plan; modest reduction in direct holdings does not by itself indicate a material change to ownership.

The report shows a small block disposal of 1,412 shares at an average price of $45 under a pre-established 10b5-1 plan adopted March 3, 2025. The filing discloses the post-transaction direct beneficial ownership of 134,232 shares. For investors, this is a transparent, rule-compliant insider sale; the size of the sale relative to total holdings reported here appears limited. No derivative transactions or additional material changes to ownership are reported.

TL;DR: Compliance-focused disclosure: the sale was executed under a documented 10b5-1 plan and properly reported on Form 4.

The filing explicitly states the transaction was made pursuant to a 10b5-1 trading plan and provides the weighted average price and the disclosed price range. Signature by an attorney-in-fact is included. From a governance perspective, the form meets disclosure requirements and offers additional transparency by offering to provide per-price sale breakdowns on request. No stock option exercises, grants, or other governance actions are included in this filing.
