Alignment policies:

  • Hedging prohibited; pledging requires prior clearance; Rule 10b5-1 trading plan constraints; quarterly and special blackout periods; pre-clearance required for officers .
  • Clawback policy adopted per Nasdaq rules for erroneous incentive compensation .
  • Stock ownership guidelines for executives not disclosed; no perquisites provided to NEOs .

Employment Terms

Severance and Change-in-Control (CIC) economics:

  • If terminated without cause (or resigns for good reason for CEO; for Machatha, without cause): base salary continuation for 9 months; lump-sum cash equal to greater of target bonus for year of termination or actual bonus for most recent fiscal year; COBRA premiums for up to 9 months; subject to release .
  • CIC Plan (amended and restated Aug 2021): 100% acceleration of unvested equity and performance-based cash unit awards upon termination without cause or resignation for good reason within 3 months before or 12 months after a CIC (double-trigger) .
  • Good Reason and Cause definitions include reduction in base/bonus >10%, material diminution of duties, relocation >50 miles; and enumerated “Cause” grounds (confidentiality breach, felony, willful misconduct, etc.) .

Investment Implications

  • Pay mix is equity-heavy, with sizable, multi-year, time-vested option grants (405,450 shares at $3.62 in 2024; 202,427 shares at $6.17 in 2025), vesting monthly over 4 years, supporting retention but creating steady potential supply as tranches vest . Trading risk is mitigated by blackout periods and pre-clearance requirements .
  • Annual bonus is formulaic to corporate goals; 2024 paid at 100% of target (40% of base) indicating goals met, but specific operational metrics are not disclosed—limiting transparency of pay-for-performance linkages for investors .
  • Ownership of 1.7% of outstanding shares aligns incentives; outstanding equity awards and RSUs provide future upside exposure, with full acceleration under double-trigger CIC potentially reducing post-transaction retention if not contractually addressed .
  • Governance signals: clawback policy in place; hedging prohibited; pledging tightly controlled; say-on-pay support was ~92% in 2024—suggesting shareholder acceptance of compensation design despite option-centric LTI .
  • Execution/retention risk: filings emphasize high dependence on Machatha’s development leadership; investors should monitor Form 4 activity for selling pressure and watch regulatory milestones tied to cash-based bonus units (NDA acceptance) as compensation-linked catalysts .
