Du Ying 4

What Happened

• Du Ying, Chairperson and CEO of Zai Lab Ltd (ZLAB), had restricted share units (RSUs) vest on July 1–2, 2026, resulting in 29,048 ADSs arising from conversion of RSUs. To cover tax withholding, 11,431 ADSs were surrendered (disposed) for total reported withholding proceeds of about $218,773. Separately, Du received a new RSU award of 80,393 ADSs on July 2, 2026.
• The withheld ADSs were used solely to satisfy tax liabilities (reported as Form 4 code F). The vesting/conversion events are reported as derivative exercises/conversions (code M) and the new award is reported as a grant (code A).

Key Details

• Transaction dates: 2026-07-01 and 2026-07-02; Form 4 filed 2026-07-06 (appears timely).
• Vesting/conversion: 18,000 ADSs (7/1) and 11,048 ADSs (7/2) — total 29,048 ADSs acquired via RSU vesting (reported as derivative exercises, code M).
• Tax withholding (dispositions): 7,083 ADSs @ $19.15 = $135,639 (7/1) and 4,348 ADSs @ $19.12 = $83,134 (7/2); total ≈ $218,773 (reported as code F).
• New grant: 80,393 RSU ADSs awarded 7/2/2026 (code A); vesting schedule noted in footnotes (multi-year vesting).
• ADS note: Each ADS represents 10 ordinary shares; filing reports amounts in ADSs (footnote).
• Shares owned after transaction: not specified in the provided filing excerpt.
• Transaction codes explained: M = exercise/conversion of derivative (RSU vesting here), F = shares withheld for taxes, A = grant/award.

Context

• These were RSU vesting events and an RSU grant, not open-market purchases or sales for investment gain. The disposals were tax-withholding (common on vesting) rather than voluntary sales of stock for cash.
• The new 80,393-RSU award is subject to multi-year vesting per footnotes; vested ADSs are delivered after each vesting date. This type of reporting is routine for executive compensation and doesn't by itself indicate a buy/sell signal.
