Board Governance

  • Board service: Co-founder; Executive Chairman (Oct 2018); Chairman & CEO since Mar 2019 .
  • Independence: Board determined all directors except Lim and Varney are independent under Nasdaq; Lim is non-independent as CEO .
  • Dual-role implications: ERAS combines CEO and Chair roles; Board established Lead Independent Director in 2023 (James A. Bristol, term through 2025 AGM) to enhance oversight and independent executive sessions .
  • Committees: Lim is not listed as a member of Audit, Compensation, or Nominating; those committees are fully independent .
  • Attendance: Board met 6 times in 2024; all directors attended at least 75% of Board and committee meetings .

Director Compensation

  • Employee directors receive no separate board pay; Lim does not receive additional compensation for board service .
  • Non-employee director program details (context for governance benchmarking): retainer $40,000; Chair/Lead Independent Director +$30,000; committee chair/member fees; equity grants increased for 2025 (initial options 240,000; annual 120,000) .

Performance & Track Record

  • Notable outcomes: Led Ignyta to acquisition by Roche and integration into Genentech; led Bonti to sale to Allergan; prior CEO at Halozyme .
  • ERAS bonus framework emphasizes clinical/regulatory milestones and operational/financial goals; 2024 payout approved at 115% of target .
  • Compensation oversight with independent consultant Alpine Rewards; Compensation Committee comprised of independent directors .

  • Equity vehicle: Awards remain predominantly stock options with multi-year monthly vesting; no RSUs or PSUs disclosed for Lim .
  • Governance protections: Clawback in place; 280G “better-off” cutback; hedging/pledging banned, supporting alignment and risk controls .

Related Party and Other Risk Indicators

  • Related party: Erasca Foundation—Lim and certain directors serve as directors; company contributed shares at IPO and made donations/loan (loan repaid) .

Total Lim beneficial ownership34,743,08212.2% of 283,265,716 outstanding shares

Investment Implications

  • Alignment: Significant skin-in-the-game (12.2% beneficial ownership) with hedging/pledging prohibition reduces misalignment and leverage risk; monthly vesting of large option grants creates ongoing potential for Form 4 activity and selling pressure around liquidity events .
  • Retention economics: Strong CIC protections (18 months base + 1.5× target bonus; 100% acceleration) and non-CIC severance (12 months base; partial acceleration) suggest low immediate departure risk but could incentivize event-driven outcomes if strategic alternatives emerge .
  • Governance: Dual CEO/Chair coupled with a Lead Independent Director and fully independent committees balances control and oversight; still a consideration for governance-sensitive investors .
  • Pay-for-performance: Bonus tied to clinical/regulatory and operational objectives with above-target payout in 2024; continued reliance on options keeps pay at-risk and levered to value creation milestones typical of development-stage biotech .
