Key Details

• Transaction date: February 17, 2026 (reported Feb 18, 2026).
• Award/acquisition (Code A): 17,140 shares granted/settled at $0.00 (performance stock units from Jan 2023; performance and vesting period ended Dec 31, 2025; settlement Feb 17, 2026) — footnotes F1 and F2.
• Tax withholding (Code F): 1,582 shares withheld/disposed at $209.01 each = $330,654 — footnote F3.

Context

• The 17,140 shares were performance stock units that vested based on a 2023 grant; these shares were deferred under Simpson’s nonqualified plan and will settle on a future date chosen by Olosky per his deferral election. The 1,582 shares were withheld by the company to satisfy tax obligations on vested restricted stock units — a routine tax-withholding action rather than an open-market sale.
