Insights

Small insider sale; ownership remains sizable.

The sale of 2,000 shares at $3.585 is a modest disposition relative to the post-transaction beneficial holding of 1,044,206 shares, so it does not materially change control or economic exposure.

This transaction was disclosed as for general operating purposes, which is a non-specific use of proceeds; investors may note the timing on 10/02/2025

Transaction size unlikely to move market; watch insider activity trend.

A sale of 2,000 shares at $3.585 is small and unlikely to affect share liquidity or price by itself. The remaining >1M-share holding means the reporting person still has substantial alignment with equity performance.

Investors who monitor insider behavior should track additional Form 4s for any pattern of sales or open-market dispositions during the coming weeks.
