Governance Assessment

  • Positive signals: Independent director with deep CNS development expertise; appointed to Compensation Committee, enhancing scientific perspective in pay decisions; no related-party transactions disclosed at appointment.
  • Alignment: Director pay structured as cash retainer plus time-vested stock options; beneficial ownership reported as <1%, indicating limited current “skin in the game” (policy-driven option grants may build alignment over time).
  • Board/committee context: Compensation Committee includes Gregory H. Bailey, M.D., who is executive chairman of Juvenescence, a >5% stockholder—committee independence is asserted as compliant, but investor-affiliation on comp committee is a governance consideration for oversight optics.
  • Risk indicators: No red flags disclosed for Brannan (no hedging/pledging, legal proceedings, or related-party transactions noted); company maintains a clawback policy applicable to executive officers’ incentive-based compensation.
