DIEKMAN JOHN D 4

What Happened
John D. Diekman, a director of Zai Lab Ltd (ZLAB), received a grant of 22,371 American Depositary Shares (ADSs) on June 17, 2026. The report lists an acquisition price of $0.00 (award/grant), so the reported cash value on the Form 4 is $0. These are restricted shares that vest in full on June 17, 2027, subject to Diekman’s continued service on the board.

Key Details

• 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).
• Vesting: Restricted shares vest in full on June 17, 2027, subject to continued board service (see footnote).
• Shares owned after transaction: Not specified in the Form 4.
• Filing: Form 4 filed with the SEC on June 22, 2026 for the June 17 transaction — this appears later than the standard two-business-day reporting window and may be a late filing.

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.
