Key Details

Transaction date: February 26, 2026; Form 4 filed February 27, 2026 (appears timely).
Grants: 66,000 units at $0.00; 96,163 units reported as N/A. Total units granted = 162,163.
Vesting: Vests in substantially equal monthly installments over one year from the grant date (footnote F1 / F3).
ADS note: Each American Depositary Share (ADS) represents 5 ordinary shares (footnote F2). The 96,163 DRSUs were granted in ADS form per the filing (footnote F3).

Context

These are compensation awards (derivative units/DRSUs) to a non-executive director, not open-market buying or selling. DRSUs convert to ADSs under the stated conversion/vesting rules and are typically paid after vesting (and possibly after separation), so they do not represent immediately tradable shares.
