Equity Ownership

HolderBeneficial Ownership (#)Composition% of Shares Outstanding
Mark G. Foletta59,371 56,398 shares held by a trust + 2,973 RSUs vesting within 60 days * (<1%)
Shares Outstanding (Record Date)392,107,501
  • Non-employee director stock ownership guideline: 2× annual equity grant; compliance required within 5 years; all directors with ≥5 years of service are in compliance as of Record Date (Foletta qualifies) .
  • Anti-hedging/pledging: company prohibits hedging; governance highlights state “No pledging or hedging of Company securities” .

Governance Assessment

  • Strengths:
    • Independent leadership: Lead Independent Director with defined authorities; Audit Chair; Board independence strong (all directors except CEO independent) .
    • Financial oversight: Board determination that Foletta is an audit committee financial expert; Audit Committee met 8 times with high average attendance (96%) .
    • Alignment: Equity-only director compensation via RSUs; ownership guidelines (2× annual grant) and anti-hedging/anti-pledging policies reinforce alignment with shareholders .
    • Accountability: Majority voting standard with resignation policy for directors failing to receive majority support .
  • Watch items:
    • CEO also serves as Chairperson; mitigated by empowered Lead Independent Director, but still a concentration of roles to monitor .
    • Director awards are time-based RSUs without performance metrics; while typical for boards, it reduces explicit pay-for-performance linkage at the director level .
    • Multiple external board responsibilities (AMN chair; Enanta audit) could pose bandwidth considerations; however, no related-party transactions disclosed and no compensation committee interlocks .
  • Attendance/engagement: Board-wide average attendance of 94%; all directors except one attended ≥75% (Foletta meets threshold) .

No related-party transactions involving Foletta or other directors above $120,000 since Jan 1, 2024; Audit Committee oversees related-party transaction approvals, reducing conflict risk .
