• Shares owned after transaction: Not disclosed on this Form 4.

Context
Share withholding to cover taxes on vested RSUs is a routine administrative action (a cashless-like settlement) and is different from an open-market sale; it generally does not indicate a change in the insider’s market view. Purchases or open-market sales are more informative about an insider’s sentiment.
