Zai Lab (ZLAB) CLO Edmondson Titus Sells 4,103 ADSs
What Happened
- Edmondson Frazor Titus III, Chief Legal Officer of Zai Lab (ticker: ZLAB), had 14,600 ADSs vest from restricted share units (RSUs) on 2026-06-25 and those ADSs were converted/received. Of those vested ADSs, 14,600 were disposed via automatic tax withholding (reported as a derivative disposition at $0). On 2026-06-26 he also sold 4,103 ADSs in an open market sale at $17.46 each, generating proceeds of $71,642.
- These transactions are routine: the RSU vesting and automatic sale to cover taxes is a common administrative event; the open-market sale was a disposal, not a purchase.
Key Details
- Transaction dates and prices:
- 2026-06-25: 14,600 ADSs acquired on conversion/vesting of RSUs (derivative event).

- Some ADSs were sold automatically to cover taxes upon vesting (F4).
- The RSUs vest in equal annual installments over four years starting 06/25/2023 (F5).
- Filing/timeliness: Form 4 was filed 2026-06-29 for transactions on 06/25–06/26; the filing appears timely.
Context
- For retail investors: this is primarily a vesting/tax-withholding event (derivative conversion of RSUs) plus an open-market sale. The derivative entries reflect RSUs converting to ADSs and shares being sold to satisfy tax obligations (a form of cashless/automatic withholding), not an exercise to hold shares as a long-term purchase.
- Such sales by executives after vesting or for tax withholding are common and do not, by themselves, indicate a change in view about the company’s prospects.
