  • Fees earned by McGuire as a TECX director were paid to Polaris Partners, highlighting an affiliated payment channel .
  • Board maintains a written Related Person Transactions Policy; Audit Committee approves only those deemed fair and in the Company’s best interests .

Independence, Policies, and Protection

  • Independence: Board determined McGuire is independent for Board service and committee standards; Audit Committee comprised solely of independent directors .
  • Insider Trading/Hedging: Company policy prohibits hedging, derivatives, publicly‑traded options, and holding common stock in margin accounts .
  • Indemnification: TECX maintains indemnification agreements for directors and officers to the fullest extent under Delaware law .
  • Executive sessions: Independent directors meet regularly without management .

Governance Assessment

  • Strengths:

    • Independent, non‑executive Chair role separates oversight from management; supports objective evaluation and risk oversight .
    • Active engagement on Audit and Nominating & Governance committees; independence affirmed under Nasdaq/SEC rules .
    • Attendance met at least the 75% threshold; regular executive sessions reinforce independent oversight .
    • Hedging and margin restrictions reduce misalignment risks (no disclosed pledging) .
  • Potential RED FLAGS:

    • Ownership/interlocks via Polaris funds (>5% holder) and director cash fees paid to Polaris create perceived conflicts; Board acknowledges and reviewed independence in light of these relationships .
    • Participation of Polaris‑affiliated entities in merger financing (Subscription/SAFEs) could raise related‑party considerations; mitigated by formal Related Person Transactions Policy and Audit Committee processes .
  • Alignment:

    • Significant beneficial ownership (6.2%) suggests skin‑in‑the‑game; director equity is time‑based without performance metrics, typical for non‑employee directors .

Overall, McGuire’s independent Chair role and committee service strengthen board effectiveness, while Polaris affiliations present manageable, disclosed conflicts subject to policy oversight and independence determinations .
