The shares were surrendered back to the issuer at $105.08 per share to satisfy tax obligations tied to vested performance stock units, resulting in a value of approximately $119,476.

Key Details

  • Transaction date: July 19, 2026; filing date: July 21, 2026 (timely within the Form 4 reporting window).
  • Shares disposed: 1,137 at $105.08 each; total ≈ $119,476.
  • Reason: Shares were withheld/disposed to satisfy taxes on vested Performance Stock Units granted in 2023 (Footnote F1).
  • Reported holdings after transaction: the filing does not state a single total beneficial-ownership figure. Footnotes note 7,168 unvested restricted shares and 4,040 performance-earned restricted shares, plus additional holdings in a 401(k) account (Footnotes F2–F3).
  • Other footnotes: Form notes outstanding Stock Appreciation Rights granted under the plan (vesting schedule and expirations) (F5). F4 indicates some prior holdings/transactions reported on earlier forms.

Context This was a routine tax-withholding disposition associated with vested equity (a common administrative action when awards vest). It should not be interpreted as a deliberate market sale signaling a change in insider sentiment. Transaction code F denotes shares surrendered or withheld to cover taxes rather than an open-market sale.
