Governance Assessment

  • Board leadership and independence: As independent Board Chair and Nominating & Corporate Governance Chair, Sams strengthens oversight, succession, and refresh; executive sessions reinforce independence.
  • Committee effectiveness: Expected committee structure post-AGM places Sams over governance and on Audit—aligning with her legal/compliance background.
  • Alignment: Material equity component and stock ownership guideline compliance support shareholder alignment; director comp predominantly stock-based (for Sams: ~$265k stock vs $50k cash, ~84% stock).
  • Conflicts/related-party exposure: None disclosed for 2024; anti-hedging/pledging and clawback policies in place.
  • Shareholder signals: High 2024 say-on-pay support (≈92%); proactive board refresh and retirement policy bolster investor confidence.
  • RED FLAGS: Administrative late Form 4 filings for all seven active non-employee directors on Aug 5, 2024 (grant reporting), attributed to company error; monitor future Section 16 timeliness.

Overall: Sams’ legal/governance expertise, independent chairmanship, and roles on Audit and Nominating position her as a stabilizing force for board effectiveness and investor confidence, with low conflict risk and strong alignment to shareholders through equity-heavy compensation and ownership policies.
