Context

• This was a compensation award, not a market purchase or sale. Grants like RSUs are common for directors and typically reflect compensation or retention incentives; they do not by themselves indicate buying or selling sentiment. The grant has no immediate cash cost to the insider, but it may be taxable when the RSUs vest and shares are delivered.
