• Robert Wunar’s annual base salary: $475,000.
• Bonus and equity: eligible for the management bonus plan with an initial target bonus of 85% of base salary (after one full quarter); subject to shareholder approval, eligible for an equity award with a grant date value of $1,500,000 (50% time-based RSUs vesting over three years; 50% performance-based PSUs).

Why It Matters

• Leadership change: a new COO can affect operational execution and strategic priorities; Wunar’s background in semiconductor and clean‑energy operations suggests continuity in relevant industry experience.
• Compensation and cash flow: the company has committed to a $475k annual salary, a potential $1.5M equity grant (pending shareholder approval), and a $200k sign-on payment — items investors may consider when assessing near‑term cash needs and potential long‑term share dilution.
• Governance note: severance and equity terms follow company policy and are subject to standard approvals and clawback provisions; there are no disclosed conflicts of interest.
