Equity Ownership

HolderBeneficial Ownership (Shares)% of OutstandingComposition
Sarah Gheuens8,888<1%Consists entirely of options exercisable as of Mar 31, 2024 or within 60 days; options held as a new director
  • Anti-hedging policy prohibits directors from short-term trading, short sales, publicly traded options, and hedging transactions in Company securities .

Governance Assessment

  • Positives: Independent director; relevant domain expertise aligning with Science Committee remit; compliant attendance; independent Board leadership with executive sessions; overboarding limits observed; anti-hedging in place .
  • Alignment: Holds director options; ability to elect equity for fees ties compensation to share performance, though largely time-based rather than performance-conditioned .
  • Potential concerns/red flags:
    • Low Say-on-Pay support: ~58% approval for 2024 NEO compensation; Board acknowledged a second consecutive year <70% and undertook shareholder engagement and added disclosure—signals investor scrutiny of pay practices .
    • Equity plan utilization/dilution: 2024 equity plan share increase approval (+2,000,000 shares); 2025 proxy proposes a further increase (+8,000,000); continued reliance on options for directors and executives elevates dilution considerations for investors .
    • Related-party exposure: Company disclosed related-party transactions involving Fairmount-affiliated entities (e.g., Zenas BioPharma, Paragon), but no related-party transactions were identified involving Gheuens personally .
  • Overall: Gheuens enhances board effectiveness on scientific oversight without evident conflicts; investor focus on compensation/dilution is primarily a Board-level issue rather than director-specific.

Note: No Form 4 insider trading transactions for Gheuens were disclosed in the proxy; the Company reported Section 16 compliance for 2023 (late filing only for a former executive), and anti-hedging policies apply to directors .
