What Happened

  • Joshua L. Smiley, President and Chief Operating Officer of Zai Lab (ZLAB), reported a small open‑market sale and several equity awards/conversions.

On 2026-03-12 there are entries showing a conversion/exercise of 6,388 derivative units and a contemporaneous disposition of 6,388 ADSs (reported at $0.00), which the filing notes are related to tax withholding/automatic sale upon vesting.

Key Details

  • Transaction dates and prices:
    • 2026-03-04: Grants/awards — 103,950 ADSs and 33,783 ADSs (RSUs), $0.00 reported (derivative awards).
    • 2026-03-12: Exercise/conversion of 6,388 derivative units (reported acquisition) and disposition of 6,388 ADSs at $0.00 (tax withholding/sale).
    • 2026-03-13: Open-market sale — 1,966 ADSs at $18.63 each, proceeds $36,623.
  • Footnotes of note:
    • Each ADS represents 10 ordinary shares (F1).
    • RSUs represent a contingent right to receive one ADS and vest per schedules (F2, F3, F6, F7).
    • Some ADSs were sold automatically to cover taxes upon vesting (F4).
    • Vesting schedules: some awards vest in equal annual installments over four years beginning 03/04/2027 (F5/F6); another RSU grant vests beginning 03/12/2026 (F7).
  • Shares owned after the transactions are not specified in the summary provided in this prompt.
  • Filing: Form 4 filed 2026-03-16 for report period 2026-03-04. The filing appears to be within required Form 4 timing for the reported transaction dates.

Context

  • These RSU grants are restricted awards (not open‑market purchases) and vest over multiple years; they do not reflect an immediate cash purchase. The 6,388‑share conversion/disposition appears tied to vesting/tax withholding (automatic sale), per filing footnotes — this is a common administrative step and not necessarily an investment signal. The small open‑market sale (1,966 ADSs, ~$36.6k) is modest relative to the aggregate grants and is factual reporting of insider activity.
