Governance Assessment

  • Strengths: Independent director serving as Compensation Committee Chair with documented use of an independent compensation consultant (Aon) and committee executive sessions without management; committee independence evaluated and affirmed; robust Board and committee attendance; director equity grants with clear vesting rules and double-trigger acceleration provisions .
  • Alignment: Director equity compensation in stock options aligns incentives with shareholder value; annual cash and committee fees are modest relative to small-cap biotech norms; directors excluded from employee option repricing and from the 2025 employee equity plan, reducing conflicts in pay decisions .
  • Potential risks/considerations: Low personal ownership (<1%) limits “skin in the game” optics; as Compensation Committee Chair, oversight of sensitive measures (e.g., 2025 Plan design amid significant warrant dilution and employee option repricing) demands continued transparency and rigorous pay-for-performance alignment; concurrent senior operating role at another biopharma may raise time-commitment perceptions though board independence is affirmed .
  • Red flags: Company pursued a one-time employee option repricing (not covering non-employee directors); this can be shareholder-sensitive but was structured with higher executive exercise prices, a 12-month retention exercise-price condition, and subject to shareholder approval, mitigating governance concerns; Aon engagement assessed for conflicts with none found .
