Context

• This is a compensation award (non-cash) rather than an open-market purchase or sale. RSU grants are routine director compensation and do not necessarily signal immediate insider buying or selling intent. Because the award is a fixed dollar amount, the number of shares granted depends on the stock price at the quarterly determination date. The RSUs only convert into shares if the vesting condition (continued service to 3/31/2027) is met.
