Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Decline: Q3 2025 revenue decreased 44.6% year-over-year to $1.029 million, driven by the absence of a large burner shipment to a California refinery that occurred in Q3 2024. Nine-month revenue declined 48.0% to $1.563 million.
• Margin Improvement: Despite lower revenue, gross margin improved to 35.8% in Q3 2025 (from 29.6% in Q3 2024) due to a higher mix of spare parts orders which carry better margins than large burner projects.
• Operating Expenses: General and Administrative (G&A) expenses increased 9.2% in Q3 2025 to $1.808 million. This increase was primarily due to a $729,000 non-cash expense from the accelerated vesting of Restricted Stock Units (RSUs) following the departure of three directors, and increased legal/audit fees related to a new "shelf" registration statement. These increases were partially offset by savings from the suspension of China operations.
• Cash Flow: Net cash used in operating activities for the nine months ended September 30, 2025, was $3.453 million, an improvement from the $3.958 million outflow in the prior year period, largely due to an increase in contract liabilities (customer prepayments).

Outlook, Risks, and Management Commentary

• Liquidity: Management believes current cash ($10.5 million) and expected collections are sufficient to fund operations for over 12 months. The company has no contractual debt obligations.
• Financing: The company entered into an At-The-Market (ATM) agreement with H.C. Wainwright on July 17, 2025, allowing for the sale of up to $10.39 million in common stock. No shares have been sold under this agreement as of the filing date.
• Nasdaq Compliance Risk: The company received a notice from Nasdaq regarding non-compliance with the minimum $1.00 bid price rule. Nasdaq granted a 180-day extension until March 30, 2026, to regain compliance. Management intends to effect a reverse stock split if necessary to meet this requirement. Failure to comply could result in delisting.
• Legal & Governance: The company resolved a special committee matter regarding director nominations through cooperation agreements, resulting in the appointment of two new directors. Legal fees increased significantly in the nine-month period due to these matters and an SEC inquiry into 2020 trading activities.
• China Operations: The Beijing subsidiary is in dormancy status, reducing ongoing operational costs while preserving the legal entity for potential future revival.

Investor Verification Checklist

• Nasdaq Bid Price: Monitor the stock price to ensure it meets the $1.00 threshold for 10 consecutive days before March 30, 2026, to avoid delisting.
• ATM Utilization: Verify if the company has begun selling shares under the new $10.39 million ATM agreement to fund operations.
• Revenue Concentration: Assess the pipeline for large burner orders, as revenue remains highly concentrated and volatile compared to the prior year.
• Share Count: Note the issuance of 756,000 shares to former directors in October 2025 (subsequent event) to settle RSU liabilities, which may impact dilution.
• Legal Costs: Monitor future G&A expenses for continued elevated legal fees related to the SEC inquiry and governance restructuring.
