Policy alignment: RNA’s Insider Trading Policy prohibits hedging, short sales, derivatives, margin purchases, and pledging of company securities by directors and employees, supporting alignment with shareholders .

Governance Assessment

  • Strengths: Independent status; service on Human Capital Management and Nominating & Corporate Governance committees; documented attendance threshold met; meaningful equity participation aligning interests; prohibitions on hedging/pledging; transparent director pay program with market benchmarking and clear vesting/CoC terms .
  • Watch items: Prior employment at BMS while RNA maintains material agreements and facility sublease with BMS/Turning Point; although independence affirmed, investors may monitor for perceived conflicts in decisions touching BMS matters. No explicit director stock ownership guideline disclosure found in proxy, limiting visibility into “skin‑in‑the‑game” expectations for directors .
  • Shareholder sentiment signal: 2024 say‑on‑pay approval was ~98.5%, indicating broad support for compensation governance at RNA (context for overall governance environment) .

RED FLAGS

  • Related‑party exposure via prior BMS employment and ongoing material relationships between RNA and BMS/Turning Point; requires continued board‑level conflict management and recusal protocols where applicable .
  • Lack of explicit disclosure of director stock ownership guidelines and compliance status in proxy reduces visibility into long‑term ownership alignment for directors .
