Securities Analyst

TL;DR: Routine tax-withholding share disposition; insider retains substantial RSU-linked ownership.

The Form 4 documents an exempt disposition where 6,730 shares were withheld to satisfy tax obligations tied to vested RSUs at $1.28 per share, a common administrative action following vesting events. Post-transaction beneficial ownership of 193,806 shares is explicitly stated and includes unvested RSU tranches from three grant dates.
