Governance Assessment

  • Strengths:
    • Independent director with extensive biotech transaction experience and governance credentials; serves on XOMA’s Nominating & Governance Committee, supporting board composition and governance oversight .
    • Strong engagement: Board met 8 times in 2024 with ≥75% attendance for all directors; independent chair with executive sessions each regular meeting enhances board independence .
    • Clear alignment mechanisms: Annual equity grant; 2024 election of options increases at‑risk exposure; equity awards subject to clawback; no repricing; no dividends on unvested awards .
    • No related-party transactions disclosed for 2024/2023; audit committee oversees related-party matters; robust insider trading/anti-hedging policy .
  • Watch items:
    • Ownership alignment primarily via vested options (69,125 exercisable; no RSUs or disclosed common shares), which can be less durable than outright share ownership from a long-term alignment perspective .
    • Board is asking shareholders to approve reincorporation to Nevada and to authorize board-only bylaw amendments—changes some investors view as reducing stockholder rights; as an N&G member, Kosacz will be involved in governance practices around these shifts .

No director-specific red flags (legal proceedings, related-party transactions, hedging/pledging, or compensation interlocks) were disclosed for Ms. Kosacz in the latest proxy .
