Additional governance provisions:
- Company has an NYSE American-compliant clawback policy for erroneously awarded compensation .

Board Governance & Roles
- Culley is an inside director (not independent) and serves as Chair of the Financial Strategy Committee; he does not receive director fees for this service. The Board Chair role is separate and held by an independent director (enhancing oversight) .
- Committee composition (as of 4/18/2025) includes Culley as Chair of the Financial Strategy Committee; Audit and Compensation Committees are fully independent .
- Meeting cadence/attendance: in 2024, the Board met 7 times and no director attended fewer than 75% of Board/committee meetings; non-employee directors meet at least quarterly in executive session .
Director & Executive Compensation Context
- 2024 Say-on-Pay support: ~96% of votes cast supported NEO compensation; the Compensation Committee took this as affirmation of the program design .
- Consultant and peers: Anderson Pay Advisors serves as independent consultant; peer group consists of small-/mid-cap, pre-commercial biotechs with Phase 2 lead programs; Committee targets competitive market percentiles to support hiring/retention .
Compensation Structure Analysis
- Equity mix and performance risk: Culley’s 2024 equity compensation consisted of options (grant-date fair value $1.50M) which have value only above exercise price, preserving performance leverage; the company used performance- and milestone-linked RSUs in 2022, but market-price RSU tranches for 2023–2025 were forfeited, indicating rigorous share-price hurdles and/or market underperformance .
- Cash vs. at-risk pay: 2024 bonus paid at 87.5% of target based on program execution and capital/budget goals; “Shareholder Value” metric paid at 50% in 2024, moderating cash payouts relative to target .
- Option economics and potential supply: With a company-wide weighted-average option exercise price ($1.60) well above the April 2025 share price ($0.41), many options are currently out-of-the-money, limiting near-term exercise-related selling pressure and aligning future upside with shareholder gains .

Investment Implications
- Pay-for-performance linkages remain meaningful. Option-heavy equity and milestone/market-linked RSUs (some forfeited) indicate significant performance risk in Culley’s equity compensation; cash bonuses flexed down with TSR underperformance factors (2024 “Shareholder Value” paid at 50%), helping maintain alignment with outcomes .
- Retention and transition risk appears moderate. Employment protections include 12 months’ salary and 100% of target bonus on a non‑CIC termination and 18 months’ salary plus 150% of target bonus and time‑based equity acceleration on a CIC termination, offering stability through potential strategic events .
- Insider selling pressure is likely constrained near term. With many options apparently underwater at April 2025 pricing (WAEP $1.60 vs price $0.41), exercise-driven supply should be limited unless the stock recovers materially, reducing technical overhang from executive option exercises in the near term .
- Governance mitigants to dual roles. Culley is CEO and a director but not Chair; the Board maintains an independent Chair and independent Audit/Compensation Committees, with quarterly executive sessions, supporting oversight of management compensation and performance .
- Shareholder support remains strong. ~96% Say‑on‑Pay support in 2024 suggests investors have been comfortable with the program design and outcomes; continued TSR improvement would likely be needed to sustain this support if equity value realization lags .
