Governance Assessment

  • Strengths:

    • Independent director with deep clinical development and public-company leadership; designated Audit Committee financial expert (supports oversight of financial reporting and risk) .
    • Active engagement across three committees, including chairing Science & Technology (alignment with FDMT’s R&D-centric strategy) .
    • Attendance at or above Board standards in 2023 and 2024, indicating engagement .
    • Equity ownership and ongoing option grants provide alignment; beneficial ownership increased from 145,368 to 167,868 shares year-over-year .
  • Watchpoints:

    • External executive role (CMO at Halozyme) introduces potential time-commitment considerations; monitoring overboarding is prudent though no conflicts disclosed .
    • Director equity is purely time-based; no performance-conditioned director awards—typical for boards but provides limited pay-for-performance linkage .
    • Change-in-control acceleration on director options is shareholder-sensitive; standard in biotech but worth monitoring .
  • Conflicts/Related Parties:

    • No related-party transactions disclosed for Theuer. Notably, a related-party agreement exists with Reignite Therapeutics involving FDMT’s CEO; not tied to Theuer .
  • Policies supporting alignment:

    • Hedging of FDMT equity prohibited by policy; reinforces alignment; pledging not disclosed .
  • Overall: Theuer’s audit expertise, committee breadth, and biotech leadership background support board effectiveness. No direct conflicts disclosed; time-commitment from external CMO role should be monitored to maintain sustained engagement .

RED FLAGS: None disclosed specific to Theuer (no related-party transactions, no hedging/pledging, attendance meets thresholds) .
