• Shares owned after the transaction: not stated in the filing.
• Relevant footnotes:
  • The 4,412 shares were issued upon vesting of RSUs under the 2025 Omnibus Equity Incentive Plan; RSUs convert one-for-one into ordinary shares (F1, F2).
  • The Aug 5 sale was to pay tax liability for the Jul 31 vesting and “does not represent a discretionary transaction by a reporting person” (F3).
  • The weighted average sale price and price range are disclosed; the reporting person can provide detailed per-trade prices on request (F4).
  • The RSUs were originally granted Sep 11, 2025 and vest in quarterly installments after a one-year cliff (F5).
• Filing timing: the Form 4 was filed on Oct 16, 2026; the reported transactions occurred on Jul 31, 2026 and Aug 5, 2026, more than two months before filing.

Why it may matter

• The filing shows RSUs vested and converted into ordinary shares, and a portion of those shares were sold specifically to cover tax withholding rather than as a discretionary open-market sale.
• The filing does not show why the insider traded or why the company acted.
