Compensation Committee, Peer Group, and Say‑on‑Pay

  • Committee/Advisor: Independent Compensation Committee (Harrison, Cole, Goldberg, Cotton) with Aon as independent advisor; committee reviews peer data, designs program, and oversees risk .
  • Peer Group: 2024 peer set of 17 life sciences/tools/diagnostics companies, selected on revenue ($150M–$1.02B at selection) and market cap ($200M–$1.7B) criteria; no fixed percentile target is used .
  • Governance Practices: Double‑trigger CIC vesting; clawback; ownership guidelines; prohibition of hedging/pledging; no post‑employment tax gross‑ups; limited perquisites; and no guaranteed bonuses .
  • Say‑on‑Pay: ~97% approval in 2024 following program changes and investor outreach addressing overlapping metrics and transparency .

Related‑Party, Compliance, and Risk Indicators

  • AltheaDx acquisition consideration: Stokes (as a prior AltheaDx holder) received initial consideration valued at ~$67,388 at the 2022 closing; no further earn‑out was paid; contingent consideration ended at $0 by 12/31/2024 .
  • Section 16 compliance: One Form 4 for Frank Stokes was filed late on Aug 13, 2024 due to an administrative error .
  • No hedging/pledging allowed; no option repricings; no special executive health/welfare benefits; no post‑employment tax gross‑ups .

Investment Implications

  • Strong pay‑for‑performance alignment: CFO compensation mix includes material equity with 2024 PSUs tied to multi‑year revenue, a new test launch, and achieving positive EBITDA by end‑2026; this emphasizes execution on growth and profitability and reduces overlap with annual metrics .
  • Retention risk appears moderate: Severance is 1x salary + target bonus outside CIC and acceleration of 12 months of time‑based equity; CIC benefits are 1x salary and prior‑year target bonus with full equity acceleration (double‑trigger), supporting continuity through strategic events .
  • Potential selling pressure from vesting: Stokes has multiple unvested RSU tranches (e.g., 48,744 time‑based RSUs from 3/4/2024 and earlier tranches), plus 16,248 2024 PSUs subject to performance; as these vest, shares may come to market, though hedging/pledging is prohibited and ownership guidelines are met, supporting alignment .
  • Governance and shareholder signals are constructive: 2024 say‑on‑pay passed with ~97% support after program refinements, indicating investor acceptance of incentive design and improved alignment .
