AttendanceBoard met 3 times in 2024; each director attended ≥75% of combined board/committee meetings during periods of service

Non‑employee director pay framework (for context): cash retainers and annual option grants per policy; not applicable to Erdtmann as an employee director .

Director Compensation (as Director)

  • As an employee director, Erdtmann received no additional compensation for board service in 2024; non‑employee director pay table excludes him by policy .

Related Party and Ownership Interlocks

  • Point Sur Investors Fund I, L.P. (228,470 sh) and Point Sur LLC (252,320 sh) are included in Erdtmann’s beneficial ownership; he and Thomas Butler are managing members of Point Sur LLC with shared voting/dispositive power over those securities .
  • Company states no related party transactions over $120,000 since Jan 1, 2024 outside of disclosed compensation arrangements; related party transaction policy places approval under Audit Committee review .

Compensation Committee Analysis

  • Composition: Bihua Chen (Chair), Eric Aguiar, M.D.; all independent under Nasdaq and non‑employee directors under Rule 16b‑3; met 2 times in 2024 .
  • Use of independent consultant: Aon Consulting engaged in 2024 to advise on program design and market data; committee assessed independence and found no conflicts . Similar engagement disclosed for 2023 .

Performance & Track Record

  • Leadership breadth increased in 2025 as he assumed PFO/PAO responsibilities following CFO resignation; supports continuity across finance and operations during transition .
  • No material legal proceedings involving executive officers disclosed .

Compliance note:

  • A prior Form 4 was filed late for Erdtmann in 2022 related to 8,400 shares acquired on April 15, 2021 (historical disclosure) .

Risk Indicators & Red Flags

  • 280G excise tax gross‑up protection in CIC (shareholder‑unfriendly, elevates potential CIC cost) .
  • 100% acceleration of unvested equity upon double‑trigger CIC termination (maximizes payout sensitivity to M&A outcomes) .
  • No 2024 cash bonuses (signals cost discipline and alignment with outcomes) .
  • Hedging, pledging, and margin use prohibited by policy (reduces alignment risks) .
  • Related‑party oversight policy in place; none above threshold disclosed since Jan 1, 2024 .

Equity Ownership & Option Liquidity Detail (Trading Pressure Lens)

  • Beneficial ownership of 7.86% (2,989,025 sh) as of Mar 31, 2025 indicates significant skin‑in‑the‑game; includes 456,205 options exercisable within 60 days that could add tradable float upon exercise .
  • Option stack features multiple strikes ($5.14–$14.44) and long expirations into 2031–2034; vesting quarterly supports steady rather than lumpy unlocks absent CIC acceleration .

Employment & Contracts Summary

CIC (double‑trigger within 30 days pre‑CIC to 12 months post‑CIC)12 months salary + up to 12 months healthcare + 12 months target bonus; 100% vesting acceleration (except performance awards per terms)
280GGross‑up protection
CovenantsConfidentiality; IP; non‑compete and customer non‑solicit during employment; employee non‑solicit for 12 months post‑employment
ClawbackSEC/Nasdaq‑compliant recovery policy (adopted Nov 17, 2023; effective Oct 2, 2023)

Investment Implications

  • Alignment: High beneficial ownership (7.86%) and prohibitions on pledging/hedging support long‑term alignment; however, 280G gross‑up and full CIC acceleration increase potential change‑in‑control costs and may draw governance scrutiny .
  • Incentive mix: Heavy reliance on time‑vested stock options (no PSUs disclosed) ties upside to share appreciation but provides limited direct linkage to operating KPIs; absence of 2024 cash bonus suggests pay responsiveness to outcomes in a challenging year .
  • Liquidity overhang: 456,205 options currently exercisable and continued quarterly vesting create ongoing potential supply; expiries 2031–2034 reduce near‑term expirational pressure, but in‑the‑money status could drive selling by affiliated entities depending on price levels .
  • Transition risk and capacity: Combining COO/President with PFO/PAO roles post‑CFO departure centralizes control, which may aid speed of execution but concentrates key person risk; presence of a Lead Independent Director adds a governance counterbalance .
