  • Related party transaction policy: Audit Committee approval required for covered related-party transactions; policy adopted at Business Combination closing .

Governance Assessment

  • Alignment: Very high ownership (33.7%) supports “skin-in-the-game” alignment but also concentration of voting power that can influence outcomes and reduce minority investor leverage .
  • Independence: Not designated an independent director, limiting eligibility for core oversight committees and raising potential conflict perceptions given external private equity leadership and ownership stake .
  • Committee roles: No committee assignments; reduces direct involvement in audit, compensation, and governance oversight relative to peers .
  • Attendance: Met at least 75% attendance threshold; Board and committees met frequently in 2024, supporting engagement .
  • Filing compliance: Minor RED FLAG — late Section 16 Form 4 (Jan 6, 2025). No additional insider trading issues disclosed .
  • Related-party exposure: Direct investment via January 2024 subscription; no Denham Capital or Three Curve Capital transactions with AIRJ operations disclosed beyond equity holdings/subscription. Audit Committee policy in place to review such transactions .

RED FLAGS

  • Not listed as independent; combined with significant stake may concentrate influence .
  • Late Form 4 filing (procedural compliance) .

Positive Signals

  • Significant beneficial ownership indicates strong alignment with shareholder value creation .
  • Extensive capital markets and energy sector experience may benefit strategic execution .

Notes on Director Compensation Program (Structure)

  • Annual cash retainer for non-employee directors: $50,000; Chair retainers: Audit $15,000; Compensation $10,000; Nominating & Governance $10,000 .
  • Annual equity grant target: $108,000 split 50% RSUs / 50% options; vests fully after ~1 year or before next annual meeting; acceleration on death/disability and certain change-in-control scenarios .
  • 2024 actual for Mr. Porter: Cash $37,500; RSUs $55,242; Options $55,243; Total $147,985 .

Overall, Porter's deep investing background and large stake provide alignment and strategic insight, while non-independence, lack of committee roles, and concentrated ownership warrant careful monitoring for board effectiveness and minority shareholder protections .
