Context

• These events are RSU vesting/settlement and a new RSU grant — not open-market buying or selling. Settling RSUs converts the economic interest (a derivative) into actual shares; it does not necessarily indicate a purchase decision or change in sentiment. Patton is a company director (not a reported 10% owner), and no sales or proceeds were reported in this filing.
