Governance Assessment
- Independence and attendance: Bridger is independent under Nasdaq rules and met the ≥75% attendance threshold; attended the 2024 annual meeting, supporting baseline governance effectiveness .
- Committee engagement: Not listed on Audit, Compensation, or Nominating committees in current configuration, which limits direct oversight duties relative to peers serving on committees .
- Pay mix and alignment: 2024 mix of $58,000 cash and $46,800 equity; outstanding RSUs (45,000) and options (67,851) indicate equity exposure, though beneficial ownership is <1% of outstanding shares .
- Related‑party exposure (historical): Independent contractor agreement (Sep 2020–Jan 2023) at $30,000/month plus 30,000‑share option; terminated in Jan 2023 and no consulting fees in 2023–2024. This historical tie is mitigated by termination and current independence status .
- Policy safeguards: Prohibition on hedging/pledging and presence of compensation recovery (clawback) policy administered by the Compensation Committee strengthen investor protections .
Red Flags
- Historical consulting relationship and option grant during service period (terminated) — monitor for any future re‑engagements or transactions .
- Not presently on standing Board committees — may reduce direct oversight participation versus peers .
