LIQT

Business Context and Reporting Period

LiqTech International, Inc. (LIQT) is a clean technology company specializing in ceramic silicon carbide filters, membranes, and filtration systems. The company operates in three segments: Water, Ceramics, and Plastics. This summary covers the unaudited quarterly report (Form 10-Q) for the period ended June 30, 2025.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 10.5% quarter-over-quarter (QoQ) and 9.8% year-over-year (YoY) for the six-month period. Growth was driven by increased sales of liquid filtration systems (including pool systems and a full-scale PureFlow system), plastics, and ceramic membranes.
• Margin Compression: Gross profit margin declined significantly from 16.0% to 9.8% (QoQ) and from 11.3% to 6.4% (YoY six-month). This was primarily due to underutilization of manufacturing capacity following a decline in Diesel Particulate Filter (DPF) sales, increased inventory write-offs, and development costs associated with the first full-scale PureFlow system delivery.
• Operating Expenses: Total operating expenses decreased 7.5% QoQ and 4.2% YoY (six-month). R&D expenses dropped 40.4% QoQ due to the exit of a loss-making external project and centralization of R&D functions.
• Net Loss: Net loss remained relatively stable, decreasing slightly by 2.3% QoQ and 0.4% YoY (six-month), despite revenue growth, due to the aforementioned margin pressures.
• Joint Venture: In January 2025, the company established a 90% owned joint venture in China (Nantong JiTRI LiqTech Green Energy Technology Co., Ltd.) to develop marine water treatment systems. The JV received R&D funding of approximately $1.1 million from its partner.

Guidance, Outlook, and Risks

• Liquidity Outlook: Management believes current cash on hand ($8.7M) and operating cash flows are sufficient to cover capital requirements for the next 12 months. However, this is subject to macroeconomic uncertainties.
• Debt Restructuring: In March 2025, the company amended its Senior Promissory Notes, extending the maturity date to May 1, 2027. Interest rates will step up to 10% starting Jan 1, 2026, with potential increases to 13-16% in the event of default. Warrants associated with the notes were repriced from $5.20 to $2.00.
• Internal Controls: The company disclosed that its disclosure controls and procedures were not effective as of June 30, 2025, due to material weaknesses in internal controls over financial reporting. Remediation efforts include hiring finance staff and implementing a new ERP system.
• Risk Factors:
  • Geopolitical & Trade: New U.S. tariffs and retaliatory measures from China and the EU could increase costs or reduce global demand.
  • Customer Concentration: The company relies on a few major customers; Customer D accounted for 36% of accounts receivable as of June 30, 2025.
  • Inventory: Continued risk of obsolescence and write-offs related to slow-moving inventory, particularly in the DPF segment.

Investor Verification Checklist

• Verify the sustainability of the revenue growth in the Water segment against the declining DPF segment.
• Assess the impact of the material weaknesses in internal controls on the reliability of future financial reporting.
• Monitor the cash burn rate relative to the $8.7M cash balance to ensure the 12-month liquidity runway holds.
• Review the terms of the amended Senior Promissory Notes, specifically the interest rate step-up clauses and the potential dilution from the repriced warrants.
• Track the progress and financial contribution of the new China joint venture.
