Context

• This was a routine tax-withholding event following PSU vesting (a cashless-type settlement where shares are retained to cover taxes), not a directional purchase or voluntary sale on the market. Such withholdings reduce the insider's reported share count but generally do not signal a change in insider sentiment.
