Key Details

• Transaction date: 2026-05-08; Report filed: 2026-05-28 (filing appears late relative to the usual 2-business-day Form 4 requirement).
• Shares disposed: 22,486 at $84.42 per share; total value ≈ $1,898,268.
• Transaction code: F — tax withholding/payment of tax liability.

Context This was a routine disposition to satisfy tax withholding on RSU awards, not an open-market sale for investment purposes; such withholdings are common when equity awards vest. The late filing may reduce the timeliness of public disclosure but does not by itself indicate substantive insider trading intent.
