Governance Assessment

  • Strengths: Independent status under SEC/Nasdaq rules; chairs Sustainability & Innovation Committee with documented 2024 activity; deep ESG domain expertise aligned to TMC’s sustainability-sensitive operations; board-wide move to accept RSUs in lieu of cash retainers in late 2024 indicates equity alignment .
  • Related-party exposure (RED FLAG): Robertsbridge (founded by May; owned by Stonehaven, where May is Deputy Chairman) has provided consulting services to TMC since April 2023, with payments totaling $304,065 in 2023 and $122,050 in 2024; May also had a personal consulting agreement (Feb–May 2024) at $8,750 per month plus 17,241 RSUs that vested on March 1, 2025. This creates potential conflicts of interest and heightened scrutiny for committee oversight and vendor relationships .
  • Compensation mix: May’s 2024 director compensation was primarily equity-based ($200,000 stock awards vs. $61,154 cash fees), supporting alignment but the concurrent consulting RSUs require careful board-level conflict management and disclosure controls .
  • Oversight considerations: May’s chair role over sustainability while his firm provides sustainability consulting to TMC necessitates robust recusal practices and independent review processes to maintain investor confidence; the proxy discloses committee charter and independent executive sessions, which partially mitigate risks .
