Context

• This filing reflects equity compensation activity (award grant and PSU vesting) and routine tax withholding, not an open-market buy or sell. The 543-share disposal was a share withholding to satisfy taxes rather than a market sale signaling sentiment. For retail investors, purchases are often more informative; this is compensation-related issuance and routine withholding.
