Key Details

  • Transaction date: 2026-01-22
  • Transaction type/code: Tax withholding to satisfy tax liability upon RSU vesting (code F)
  • Shares withheld/disposed: 1,198 at $68.37 per share — total ≈ $81,907
  • Shares owned after transaction: Not disclosed in the filing
  • Footnote: F1 — Represents shares withheld to satisfy tax withholding obligations applicable to the vesting of restricted stock units that vested on January 22, 2026.

Context

  • This transaction reflects routine tax withholding when RSUs vest (a cashless/cash-settlement-style withholding), not an independent decision to sell shares in the market. Such withholdings are common and do not necessarily indicate the insider’s view on the company’s prospects. Purchases and open-market sales are generally more indicative of sentiment than tax-withholding dispositions.
