Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 53.6% quarter-over-quarter (QoQ) and 19.5% year-over-year (YoY) for the nine-month period. Growth was driven by increased sales of liquid filtration systems (including a full-scale PureFlow system delivery) and plastics products, partially offset by a decline in Diesel Particulate Filter (DPF) deliveries.
- Profitability Improvement: The company returned to gross profitability in Q3 2025 ($747k) compared to a gross loss of $(209k) in Q3 2024. Gross margin improved to 19.6% from -8.5% due to better manufacturing capacity utilization and lower depreciation, despite inventory write-offs related to DPFs.
- Expense Reduction: Total operating expenses decreased 12.6% QoQ and 6.9% YoY (nine months). This was driven by reduced R&D costs (streamlining of functions) and lower G&A expenses (reduced external consulting and recruitment costs), partially offset by costs associated with a new joint venture in China.
- Net Loss Reduction: Net loss decreased 48.6% QoQ and 18.5% YoY (nine months) due to revenue growth and expense management.
Guidance, Outlook, Risks, and Unusual Items
- Liquidity Outlook: Management believes current cash ($7.35M) and operating cash flows are sufficient to cover capital requirements for the next 12 months, despite macroeconomic uncertainties.
- Joint Venture: In January 2025, the company established a 90% owned joint venture in China (Nantong JiTRI LiqTech) to develop marine water treatment systems. The JV received R&D funding of approximately $1.2M from its partner, classified as a long-term loan.
- Debt Restructuring: In March 2025, the company amended its Senior Promissory Notes, extending the maturity to May 1, 2027. Interest rates will step up to 10% starting Jan 1, 2026, with potential increases to 13-16% upon default. Warrants associated with the notes were repriced from $5.20 to $2.00.
- Risk Factors: Significant risks include exposure to global trade restrictions and tariffs (specifically U.S.-China-EU tensions), geopolitical instability, and dependence on a few major customers (Customer A represented 13% of Q3 revenue).
- Internal Controls: Management concluded that disclosure controls and procedures were not effective as of September 30, 2025, due to material weaknesses in internal controls over financial reporting. Remediation efforts are ongoing.
Investor Verification Checklist
- Verify the sustainability of the 19.6% gross margin in Q3, given the historical volatility and reliance on specific system deliveries.
- Assess the impact of the new tariff landscape on the company's supply chain and export costs, particularly for operations in China and the U.S.
- Review the status of remediation for the material weaknesses in internal controls over financial reporting.
- Monitor the performance and cash burn of the new China joint venture and the terms of the related party loan.
- Confirm the company's ability to service its debt obligations, including the Senior Promissory Notes with step-up interest rates, given the continued net losses.
