Context

• Restricted share awards are typically part of executive compensation and vest over time; they do not represent an immediate market purchase or sale. Because these shares are subject to vesting, they may not be transferable or salable until vesting conditions are met. This transaction should be viewed as compensation-related rather than a direct signal of buying or selling intent.
