Governance and compliance:

  • Clawback policy (SEC/Nasdaq compliant) adopted Sept 2023; executives executed acknowledgments .
  • Insider Trading Policy prohibits hedging, derivatives, short sales, margin purchases, and pledging; applies to directors/officers and households .

Board Governance (Boyce as Director)

  • Board class/tenure: Class I director; CEO and non-independent .
  • Committees: Boyce does not serve on committees (Audit, Human Capital Management, Nominating & Corporate Governance are fully independent) .
  • Board leadership: Separated Chair (Troy Wilson, independent) and CEO roles; Board affirms structure appropriate; continues to review .
  • Meeting attendance: Board met four times in 2024; each director attended ≥75% of Board/committee meetings .
  • Director compensation: Employee directors (including Boyce) receive no additional pay for Board service; non-employee director retainer and equity program disclosed and updated in April 2025 .

Compensation Structure Analysis

  • Mix and shift: 2024 saw a significant increase in performance-linked and equity compensation driven by special PSUs tied to three near-term program goals (del-desiran, del-brax, del-zota), while option grant value declined versus 2023; base salary rose 4% .
  • At-risk pay: Bonus entirely linked to corporate metrics and individual assessment, with 150% corporate performance determination for 2024; equity vests over multi-year/service or upon clinical milestones, reinforcing retention and execution incentives .
  • Shareholder safeguards: No hedging/pledging; double-trigger severance; clawback policy; independent compensation consultant (Alpine) and peer benchmarking at ~50th–75th percentile .
  • Say-on-pay support: Very strong in 2024 (~98.5%); 2025 votes cast show continued majority support .

Additional Data Points

  • Beneficial Ownership (as of 4/17/2025): 1,966,740 shares (1.61%); company had 120,520,928 shares outstanding .
  • Executive and director ownership footnotes list CEO’s options exercisable within 60 days (1,543,306 shares) .
  • Pay versus performance table ties compensation actually paid to stock performance; 2024 TSR recovery to $162 (from $50 in 2023) aligns with clinical and M&A catalysts .

Investment Implications

  • Alignment: High equity exposure (large option holdings, multi-year RSUs, and 2024 PSUs tied to discrete clinical/commercialization goals) creates strong alignment with value creation into key catalysts and the pending Novartis acquisition; hedging/pledging prohibitions and clawback enhance governance quality .
  • Retention/pressure: 2024 realized option exercises and vested shares indicate monetization capacity; however, CIC protections and PSU structures create strong incentives to remain through closing and program milestones; potential equity acceleration at CIC can create event-driven supply post-close but also mitigates retention risk pre-close .
  • Pay-for-performance: 2024 150% bonus payout reflects achievement on regulatory alignment, Phase 3 initiation, BLA path, and pipeline progress; special PSUs further weight pay to milestone execution across the three lead programs—positive for execution discipline into the transaction horizon .
  • Governance: Separate Chair/CEO, independent committees, strong say-on-pay support, and use of an independent consultant/peer group benchmarking support governance quality and reduce compensation risk .
