Section 16 compliance:

Governance Assessment
- Strengths: Independent director; chairs Compensation Committee with use of independent advisor (Aon); committee structure and responsibilities clear; strong attendance and annual meeting participation; prohibition on hedging; director equity vests annually and accelerates on CoC, aligning interests.
- Compensation alignment: 2024 director pay heavily equity-weighted (RSUs $119,936 vs. $65,000 cash for Arienzo); 2025 adjustments move cash and equity toward market median, addressing prior below-25th-percentile positioning—positive responsiveness to market benchmarks.
- Potential conflicts: No related-party transactions identified involving Dr. Arienzo; Board confirms independence of all non-employee directors; Compensation Committee interlocks absent.
- RED FLAGS: None evident related to attendance, related-party transactions, hedging/pledging (hedging prohibited; pledging not addressed); no option repricing authority under plan; director cap set at $750,000 total value (cash+equity) but Committee indicates no intent to grant at limit.
Overall signal: As Compensation Chair and Nominating & Governance member, Arienzo appears engaged and independent, with governance processes (consultant use, policy updates) aimed at aligning director pay with market norms while maintaining equity-based alignment with shareholders.
