Context

• This was a vesting/conversion of performance-based awards, not an open-market purchase or a deliberate sale for investment reasons. The 4,260-share sale was a routine tax-withholding (cashless) disposition tied to the vesting event. Such withholding sales are common and do not necessarily signal a change in the insider’s view of the company.
