Insights

Securities Analyst

TL;DR: Insider sale of 15,391 shares under a pre-arranged 10b5-1 plan; ownership remains large at 2.38M shares.

The Form 4 discloses a routine, pre-scheduled sale by CEO and director Scott Keeney. The sale was effected under a Rule 10b5-1 plan adopted on 06/12/2025, which typically indicates the trades were pre-authorized and not made on the basis of inside information. The reported weighted average price was $28.84, within a narrow $28.62–$29.12 range. Post-transaction beneficial ownership remains substantial at 2,381,545 shares, which includes both common stock and unvested restricted stock units. From an analytical standpoint, this filing is informative but not, by itself, a material corporate event.

Corporate Governance Expert

TL;DR: Transaction follows a documented 10b5-1 plan; disclosure appears complete and compliant.

The disclosure specifies the plan adoption date and provides a weighted average sale price and price range, and it notes that the reporting person will provide breakdowns of per-price sales upon request. The filing also clarifies that the post-sale figure includes unvested restricted stock units. These elements align with standard disclosure practices for officer/director sales and support transparency for shareholders and regulators. There is no indication in the filing of amendment or corrective action needed.
