  • Tax withholding: 1,865 shares surrendered to issuer to cover withholding (total ~$388,619) per footnote F2 (routine tax withholding on RSU vesting).
  • Footnotes: F1 = award of restricted stock units; F2 = disposition to issuer solely to cover tax withholding; F3 = 69 shares via dividend reinvestment plan reported early; F4 = note about option vesting schedule (appears for context but no option exercises reported here).
  • Shares owned after these transactions: not specified in the provided filing excerpt.
  • Filing timeliness: Reported on Feb 20, 2026 for transactions dated Feb 18, 2026—filed within the typical two-business-day Form 4 reporting window.

Context: These entries reflect compensation-related RSU awards and routine tax-withholding (a cashless surrender), not an open-market purchase or intentional sell-for-profit. Awards increase potential future ownership as RSUs vest; the withheld shares are a standard administrative step to satisfy payroll taxes.
