Insights

Corporate Governance Expert

TL;DR: Insider sales were executed under a pre-established 10b5-1 plan, indicating planned, compliant disposition rather than opportunistic trading.

The Form 4 shows routine disposition activity by a senior officer under a documented 10b5-1 plan adopted 06/05/2025. The filing lists two sale dates totaling 2,702 shares and reports remaining beneficial ownership of 73,587 shares.

Securities Analyst

TL;DR: Sales represent a small, disclosed reduction in an officer's stake; no earnings or material corporate events are reported.

The transactions—the sale of 424 shares at $8.98 and 2,278 shares at a weighted average of $8.689—are specific and limited in size. The filer affirms the trades were executed under a 10b5-1 plan and offers to provide breakdowns of prices within the stated $8.51–$8.82 range on request. There is no indication in this Form 4 of derivative activity or other material changes to ownership beyond these non-derivative sales.
