  • Related Person Transactions Policy requires audit committee approval; focus on fairness and independence .

Compensation Committee Analysis (Context)

  • Compensation Committee retained Compensia; committee assessed consultant independence and reported no conflicts of interest .
  • Director fee caps: Aggregate outside director compensation limited to $750,000 per fiscal year .

Governance Assessment

  • Strengths:

    • Independent director; extensive scientific and policy credentials; chair of nominating & governance committee .
    • Clear prohibition on hedging/pledging; change‑in‑control vesting clarity for directors .
    • Strong shareholder support in 2024 director election (high “For” vote) .
  • RED FLAGS:

    • Attendance shortfall: Dr. Chu attended less than 75% of board/committee meetings in 2024, signalling engagement risk .
    • Nominating & Governance Committee held no separate meetings in 2024 despite its oversight mandate; potential committee effectiveness concern under his chairmanship .
    • 2024 director “Option Awards” arose from Amprius Holdings (not AMPX), adding structural complexity to director equity profile .
  • Net view: While Chu brings exceptional credentials and remains independent, the 2024 attendance gap and inactive nominating & governance calendar warrant monitoring. Investors should track improvements in committee activity, attendance, and ongoing independence safeguards to maintain confidence .
