Insights

Securities Analyst

TL;DR: Routine insider tax-withholding sale under a 10b5-1 plan; modest volume relative to total reported holdings.

The report documents a controlled disposition of 1,642 shares at a weighted average price of $1.6295 per share executed pursuant to a 10b5-1 trading plan to satisfy tax withholding on vested restricted stock. The filing also discloses 3,845,462 shares of direct beneficial ownership and 22,017.45 shares held indirectly in a 401(k). From a trading-impact perspective, the transaction appears administrative in nature rather than a strategic sale, and the filer commits to provide further breakdown of prices within the reported range upon request.

Corporate Governance Expert
