Zai Lab (ZLAB) CFO Chen Yajing Sells 1,703 ADS

What Happened

  • Chen Yajing, Chief Financial Officer of Zai Lab (ZLAB), reported several transactions. Most notably she sold 1,703 American Depositary Shares (ADSs) in an open-market sale on 2026-03-13 at $18.63 per ADS for total proceeds of $31,723.
  • The filing also shows grants on 2026-03-04 of RSUs totaling 110,187 ADSs (83,160 ADSs + 27,027 ADSs) reported as awards at $0 cost, and a conversion/exercise-type transaction of 4,258 ADSs on 2026-03-12 that was recorded as both an acquisition and a disposition (reported at $0), consistent with shares being converted/withheld rather than net cash proceeds. Sales to cover taxes are indicated in the footnotes.

Key Details

  • Transaction dates/prices:
    • 2026-03-04: Grants (A) — 83,160 ADSs and 27,027 ADSs (awards; $0.00 each).
    • 2026-03-12: Exercise/conversion of derivative (M) — 4,258 ADSs (acquired) and corresponding 4,258 ADSs (disposed) reported at $0.00 (derivative/tax withholding).
    • 2026-03-13: Open-market sale (S) — 1,703 ADSs @ $18.63 = $31,723 total.
  • Shares owned after transaction: Not specified in the provided excerpt of the filing.
  • Notable footnotes:
    • F1: 1 ADS = 10 ordinary shares; reporting is in ADSs.
    • F2–F3, F6–F7: RSUs represent contingent rights to receive ADSs; vesting schedules begin in 2026–2027 and vest in equal annual installments over four years.
    • F4: Some ADSs were sold automatically to cover taxes upon vesting (tax withholding/cashless-type treatment).
  • Filing timeliness: The grants dated 2026-03-04 were reported on 2026-03-16 — later than the typical 2-business-day Form 4 window for that grant date (the filing therefore appears late for the 03/04 grant).

Context

  • The awards are RSUs (not open-market purchases) and vest over time; they do not indicate an immediate cash outlay by the insider.
  • The 4,258-ADS exercise/conversion with $0 proceeds and the footnote about automatic sales to cover taxes suggest a cashless/withholding action rather than a market sale for cash. The 1,703-ADS sale on 03/13 was an ordinary open-market disposition that generated $31,723.
  • These filings are factual disclosures of insider activity; they do not by themselves explain the insider’s motives or predict company performance.
