Insights

Equity compensation & insider trading analyst

Routine tax sale of 112,009 RSU-related shares; neutral signal.

The director sold 112,009 shares at a $2.695 weighted average, within a $2.68–$2.731 range, expressly to satisfy tax obligations from previously vested RSUs. Such sales are commonly administrative and tied to compensation mechanics rather than changing sentiment.

Post-sale holdings remain at 265,505 shares, indicating continued exposure. Because this activity is linked to withholding and not a new grant or broader disposition, it does not materially alter the investment thesis.
