Context

RSUs are awards that convert into shares when they vest; the $0.00 grant price is standard for awards (not a market purchase). The paired conversion/acquisition and disposal of 2,799 derivative shares typically reflects net settlement or withholding tied to a vesting event rather than an open-market sale (no proceeds were reported). This activity is an award/settlement event, not a discretionary purchase or sale on the open market.
