Expertise & Qualifications

  • Audit committee financial expert with requisite Nasdaq financial sophistication; chairs Audit and Nominating & Governance .
  • Deep CFO background across public and private life sciences/tech; served as CFO of Absci, Dendreon, Affymetrix, Iovance, StemCells, Vineti .
  • Education: B.S. Accounting (DePaul); MBA (Northwestern Kellogg) .

Governance Assessment

Strengths

  • Independent director with significant financial expertise; chairs key oversight committees (Audit; Nominating & Governance) .
  • Consistent ≥75% meeting attendance in FY2024; multi-year service provides continuity .
  • Ownership is positive but modest; equity component of director pay aligns some interests with shareholders .

Watch items / RED FLAGS

  • Annual meeting engagement: no directors attended the 2024 annual meeting; this is a board-wide engagement concern .
  • Equity-heavy director compensation increased YoY (cash and stock awards rose from 2023 to 2024), and October 2025 option grants were 75% immediately vested, reducing retention incentive and creating potential optics issues on alignment and dilution .
  • Historical association: Dendreon filed Chapter 11 in 2014 after his CFO tenure (contextual track record consideration) .
  • Section 16(a) compliance: the company disclosed late Form 4 filings in 2023 by several directors including Schiffman (administrative, but a minor compliance flag) .
  • Share overhang/dilution backdrop: Board sought to increase LTIP pool to 400,000 shares in Sept 2025, raising potential dilution; not director-specific but relevant to equity alignment optics .

Policy framework

  • Insider trading policy prohibits hedging/pledging without advance CFO approval (alignment measure) .
  • Plan includes clawback/recoupment on restatement per Board policy .
