Context

• This was a routine tax-withholding transaction tied to RSU vesting (a cashless withholding), not an open-market sale or a buy. Such withholdings are common and typically reflect tax obligations rather than a deliberate decision to sell shares for investment reasons. Purchases or open-market sales tend to be more informative about insider sentiment.
