Zai Lab Ltd 4

Du Ying, Chairperson & CEO of Zai Lab Ltd, had 58,800 RSUs vest into ADSs and then sold 24,543 ADSs at about $17.46 each to cover taxes, ending with 1,192,840 ADSs owned.

On June 25, 2026, Zai Lab Ltd Chairperson & CEO Du Ying acquired 58,800 American Depositary Shares (ADSs) upon the vesting and settlement of an equal number of Restricted Share Units, increasing her direct holdings to 1,217,383 ADSs. The RSUs, each representing a right to receive one ADS, vested as part of a multi‑year compensation schedule, and on June 26, 2026, 24,543 of the newly delivered ADSs were automatically sold at an average price of $17.461 per ADS solely to cover tax withholding obligations, leaving Du Ying with 1,192,840 ADSs directly owned after the sale. Assuming the reported sale price approximates market value, the tax‑related sale was worth roughly $429,000, and her remaining ADS holdings are valued at approximately $20.8 million. Overall, the filing reflects routine equity compensation vesting coupled with an automatic sale to satisfy taxes rather than a discretionary open‑market purchase or sale.
