The withholding is reported as a disposition (code F) at a reported price of $78.27 per share, totaling approximately $2,863,664.

Key Details

• Transaction date: 2026-09-07; Form 4 filed: 2026-09-09 (filed within the typical 2-business-day window).
• Reported price: $78.27 per share (footnote says this is the Nasdaq closing price on Sept 4, 2026).
• Shares withheld/disposed: 36,587; reported value ≈ $2,863,664.
• Shares owned after transaction: not specified in the provided filing excerpt.
• Footnotes:
  • F1: Shares withheld to satisfy tax withholding on vesting under the 2022 LTIP.
  • F3: Reporting includes 41,256 shares from the 2022 LTIP and 194,411 shares underlying deferred bonus awards (each a contingent right to one share upon vesting).

Context

• This was a tax-withholding/net-share settlement (F code), not an open-market sale. Such withholdings are routine when equity awards vest and generally reflect tax obligations rather than a discretionary sale by the insider.
• The filing indicates vested awards and deferred bonus entitlements remain part of the CEO’s compensation structure; the withheld shares were used only to cover taxes on vesting.
