Equity Ownership

HolderShares Beneficially Owned% OutstandingNotes
J. Michael DiMaio, M.D.2,517,552 9.8% Includes 25,644 options exercisable within 60 days; based on 25,628,121 shares outstanding (4/15/2025)
  • Lock-ups: On Feb 7, 2024, Dr. DiMaio and Erich Spangenberg (together ~45% then) agreed to extend their lock-up by six months under the Registration Rights/Lock-Up Agreement—a positive alignment signal .
  • Financing lock-up: DiMaio is listed among “Lock-Up Parties” for the October 2025 financing transaction, indicating continued lock-up commitments around capital raising .

Related-Party Exposure

  • The company disclosed a 2024–2025 investment and subsequent note conversion involving an affiliate of its largest shareholder into Spectral IP; no DiMaio-specific related-party transaction was disclosed. The company maintains a written related-person transaction policy and process .

Risk Indicators & Red Flags

  • Non-independence and role concentration: Board Chair and Chair of Nominating & Corporate Governance and Science & Technology; also on Executive Committee. This concentrates governance influence in a non‑independent director .
  • Hedging policy gap: The company discloses no policy preventing director/employee hedging or derivatives transactions in company equity beyond insider trading restrictions—a shareholder-unfriendly practice in many governance frameworks .
  • Investor vote signal: DiMaio’s “For” votes (7.26M) lagged peers (~9.94–9.97M), suggesting investor concern versus other nominees .

Governance Assessment

  • Strengths: Deep clinical/scientific expertise aligned with product and regulatory pathway; significant equity ownership (9.8%) aligns interests; historical lock-up extensions reinforce long-term focus .
  • Concerns: Not independent; concentration of power as Board Chair plus chairing Nominating & Governance and SciTech; Executive Committee membership; absence of anti-hedging policy; comparatively lower shareholder support in 2025 director vote .
  • Compensation/Alignment: Director pay modest; mix includes equity under the 2023 LTIP with clawback coverage; no director-specific performance conditions disclosed for 2024 .
