Key Details

• Transaction date: 2026-02-11; Filing date: 2026-02-13 (filed within the typical 2-business-day window).
• Price per share: $132.16; Total value withheld/disposed: $5,419.
• Shares withheld to cover tax liability (transaction code F); this is a tax-withholding disposition, not an open-market sale.

Context

• This was a routine tax-withholding event tied to RSU vesting (including dividend-equivalent amounts), not a discretionary sale or purchase in the open market. Such withholdings are common when equity awards vest and do not by themselves indicate the insider’s view on the company’s stock.
