  • Alignment: Receives annual equity grants; holds options/RSUs, supporting long-term alignment .
  • Potential conflicts and monitoring:
    • Baker Bros. affiliation: As a Partner at a major shareholder, perceived conflicts can arise; mitigants include formal independence determinations, Governance Committee leadership by Biggar, and related-party transaction oversight by Audit Committee under written policy .
  • Compensation structure: Director pay is market-based cash retainer plus equity, with 2025 increases; no performance pay reduces pay-risk but places emphasis on fixed/equity mix .
  • Shareholder signals: Strong say-on-pay support in 2024 (98%) reflects broad approval of compensation governance, though primarily pertains to executives .

RED FLAGS to watch: Ongoing oversight of Baker Bros. influence given fund’s multi-class holdings and board presence; ensure continued rigorous recusal on any related-party matters and transparent disclosure under the related-person transaction policy .
