Key Details

• Transactions: tax-withholding on RSU vesting (Code F) and open-market sale (Code S).
• 2026-02-27: 1,996 shares withheld @ $36.47 = $72,794 (F1 indicates shares withheld to cover taxes on vested RSUs).
• 2026-03-02: 2,598 shares sold open market @ $35.00 = $90,930.
• Combined value of dispositions shown: $163,724.
• Shares owned following these transactions: not specified in the provided filing excerpt.
• Filing: Form 4 filed 2026-03-03 (appears timely given the transaction dates).

Context

• The F-coded transaction is a routine tax-withholding on RSU vesting (company retained shares to satisfy tax obligations), not a discretionary purchase/sale decision.
• The open-market sale is a typical insider disposition; sales are common and do not necessarily indicate a change in company outlook.
• For retail investors, purchases by insiders typically carry more interpretive weight than routine sales or tax-related withholdings.
