Governance Assessment

  • Controlled company with concentrated voting power: Mr. Comora, through OPAL Holdco/Hillman/Fortistar, controls a substantial majority of voting power (89.5%), limiting minority shareholder influence; OPAL utilizes Nasdaq “controlled company” exemptions, including for the compensation committee (RED FLAG for independence and board effectiveness).
  • Familial relationship with management: Mr. Comora is the father of Co‑CEO Adam Comora, elevating potential conflicts in oversight and compensation decisions (RED FLAG).
  • Related‑party transactions: Multiple ongoing arrangements with entities controlled by or affiliated with Mr. Comora (CoStar IT services, FS2 administrative services, interim CFO through Fortistar, Wasatch RNG option/services) create recurring related‑party exposure requiring robust Audit Committee oversight (RED FLAG).
  • Pledging and alignment: Company policy prohibits pledging by directors and executive officers; however, Hillman’s Class D shares (controlled via Fortistar/Comora) are pledged to a bank, introducing collateral risk despite the anti‑pledging posture (RED FLAG).
  • Attendance and engagement: Board held 10 meetings; each director attended at least 75%; five executive sessions indicate active independent director engagement.
  • Director pay mix: Standard structure with cash retainer and time‑based RSUs; no performance metrics tied to director equity; Mr. Comora’s 2024 total was $210,000 (cash $75,000; equity $135,000).
  • Compensation consultant independence: Korn Ferry engaged; Compensation Committee determined the consultant was independent; helpful for process quality given controlled company status.

Overall, governance risks center on Mr. Comora’s dominant voting control, family relationship with the Co‑CEO, and recurring related‑party transactions. These factors can impair perceived board independence and raise conflict‑management demands; strong Audit Committee oversight, transparent related‑party review, and continued use of executive sessions are important mitigants.
