Related Party Transactions and Conflicts

  • Oversight: Corporate Governance & Nominating Committee (where Myers serves) oversees board independence, conflicts of interest, reviews related party transactions alongside the Audit Committee per charters .
  • Transactions: ACLX has material agreements with Kite/Gilead (upfront $225M in Feb 2023; $85M in Nov 2023; $68.3M clinical milestone in 2024; up to ~$3.9B potential milestones); Gilead holds >5% equity and has a standstill/registration rights agreement; these are governed under related‑party policies and audit committee review .
  • No Myers‑specific related party transactions disclosed .

Compensation Committee Analysis (Board Context)

  • Compensation Committee members: Jill Carroll (Chair), Kavita Patel, David Lubner—each independent; advisor Meridian Compensation Partners; use of peer group, clawback policy adopted Sept 2023 for executives; no excise tax gross‑ups; prohibition on hedging/pledging .

Say‑on‑Pay & Shareholder Feedback (Board Context)

  • 2024 Say‑on‑Pay approval: ~56.4% (excluding abstentions and broker non‑votes); ACLX conducted outreach to top holders and expanded disclosure on pay philosophy, peer group, and CEO performance RSUs in response .

Governance Assessment

  • Strengths: Independent status; healthcare operations expertise aligned with ACLX’s commercialization trajectory; service on Corporate Governance & Nominating (focus on independence, conflicts, director education and evaluation, and stock ownership guideline monitoring) .
  • Alignment: Director equity awards and cash retainers are standard for growth biopharma; change‑in‑control equity acceleration is customary; company prohibits hedging/pledging, supporting alignment .
  • Engagement signals: Board holds executive sessions after every meeting; conducts assessments; diversity targets and disclosure suggest active governance; Myers appointment adds payer/operator perspective as ACLX approaches commercialization .
  • Watch items: Dual CEO/Chair with no Lead Independent Director (mitigated by executive sessions/feedback process); significant related‑party exposure with Kite/Gilead requires robust committee oversight; limited disclosed ownership for Myers (0 shares as of 4/4/2025) pending future director grants .
