Corporate Insider Trading Expert

Insider sold 192 shares at $10.30 and received 195 fully vested RSUs on 09/30/2025.

The filing documents a small sale of 192 shares at $10.30, reducing the reporting person's direct holdings to 12,529 shares. Concurrently, the reporting person received 195 RSUs that are described as fully vested and immediately exercisable with a $0 exercise price, making them economically equivalent to common shares.

Because the RSUs vest immediately and have no expiration date per the filing, they convert to economic ownership without additional cash cost; the net effect disclosed is a modest cash sale paired with near‑term equity retention through RSUs.
