- Transaction date: June 17, 2026; transaction type: Award/Grant (code A); reported price: $0.00.
- Quantity: 22,371 ADSs. Each ADS represents 10 ordinary shares (reporting is in ADSs).

- Shares owned after transaction: Not specified in the Form 4.

Context
This was a time‑based restricted share award (not a market purchase or sale). Restricted awards are commonly used for compensation/retention and do not by themselves indicate a near‑term change in insider sentiment. Because each ADS equals ten ordinary shares, the 22,371 ADSs represent 223,710 ordinary shares on an as‑converted basis.
