Key Details
- Transaction date: June 17, 2026; Form 4 filed: June 22, 2026 (five days after the transaction). Note: Form 4 is generally due within two business days of the transaction, so this filing was later than typical.
- Shares granted: 22,371 ADSs; Price: $0.00 per ADS; Reported total value: $0.
- ADS conversion: 1 ADS = 10 ordinary shares (F1).
- Vesting: Restricted shares vest in full on June 17, 2027, contingent on continued board service (F2).
- Shares owned after the transaction: not specified in the provided excerpt of the filing.
Context
- This was a compensation grant of restricted ADSs (an award), not an open-market purchase or sale. Such grants are commonly used for director compensation and do not represent an immediate market purchase or sale — the shares are subject to a one-year vesting condition before becoming transferable.
