Expertise & Qualifications

  • ABMG-certified clinical and molecular geneticist; academic leadership in precision medicine .
  • Senior hospital leadership (Chair of Pediatrics, Boston Children’s Hospital) .
  • Advanced degrees in biochemistry, medicine, and genetics (Cornell; Cornell University Medical College; Rockefeller University) .

Equity Ownership

As-of DateShares Beneficially Owned% of Shares OutstandingComposition
March 31, 202558,576 <1% Entirely options exercisable within 60 days
June 30, 2025103,576 <1% Entirely options exercisable within 60 days
  • Insider trading/pledging policy: Company policy prohibits short sales, derivatives, and hedging or pledging by directors and officers .

Governance Assessment

  • Independence and engagement: Chung is independent and met ≥75% attendance in 2024, serving actively on Audit and Nominating & Governance committees—supportive of board effectiveness .
  • Committee expertise and oversight: Audit Committee (with Chung as member) met 5 times; oversight includes financial reporting integrity and related-person transaction review; Michael Kelly designated “financial expert,” which strengthens committee rigor .
  • Compensation structure: Director pay is conservative, mainly cash retainers plus annual stock options; cash retainers modestly increased in May 2024 to market-align. Chung’s 2024 director pay totaled $294,716 (cash $57,188; option grant fair value $237,528) .
  • Alignment: Beneficial ownership reflects vested/exercisable options; holdings remain <1% of shares outstanding, typical for independent directors. No pledging reported; policy forbids hedging/pledging .
  • Related-party conflicts: Disclosed related-person transactions involve BMS equity/collaboration, David Liu consulting, Marrazzo advisory, and Myeloid settlement (with a Newpath/board-affiliated common director), but none name Chung—no direct related-party exposure identified for her .
  • RED FLAGS:
    • Option Repricing Proposal included non-employee directors due to deeply underwater options ($7.68–$17.00 strikes vs $2.47 FMV); while intended to restore incentive value, director repricing can be viewed as shareholder-unfriendly if not tightly conditioned—monitor implementation terms and impact on alignment .
    • Board has no designated chair or lead independent director; though reviewed by independent directors, some investors prefer a clear independent leadership counterweight .
    • Board-wide attendance issue limited to Robert Nelsen (<75% in 2024); not applicable to Chung but signals oversight to track .

Net: Chung’s medical-genetics depth and governance independence, coupled with active committee roles and solid attendance, support investor confidence. Repricing optics require scrutiny; absence of related-party ties for Chung and hedging/pledging prohibitions mitigate alignment concerns .
