Recent Operational Highlights

• the first U.S. pool system order for three systems to be installed at the Weston County School District #1 Aquatic Center in Newcastle, Wyoming;
• one in partnership with Lotec for a new large-scale commercial pool project in Den Helder, Netherlands;
• and a follow on record order in partnership with Waterco Limited for 10 systems for the Plumpton Aquatic and Leisure Centre in Fraser Rise, Victoria, Australia.
• Two systems delivered during the first quarter for marine dual-fuel engine water treatment for LNG vessels with two more expected to be delivered during the second quarter. Further sustainable order flow is expected throughout 2026 driven by the Company’s China JV. First quarter revenue from the marine business totaled $0.8 million compared to $0.2 million in the prior-year quarter.
• Commenced a new pilot program in West Texas for produced water treatment with an energy services and solutions company.
• Diesel particle filters (DPF) and membrane business experienced growth during the first quarter to $1.3 million compared to $1.0 million in the prior-year quarter, driven by strong order flow from both existing and new customers and renewed focus within this segment.
• Plastic revenue increased 5%, totaling $1.0 million during the quarter and driven primarily by strong activity within food processing.

Management Commentary

“LiqTech’s first quarter results were in line with our expectations and reflect the continued execution of our strategy to place a greater emphasis on more predictable end markets,” commented Fei Chen, CEO of LiqTech. “Importantly, we are reiterating our 2026 outlook for revenue growth, which we believe underscores the progress we are making in building a more balanced business. We believe that the nature of our business and associated sales cycle mean that the improvements we made in 2025 will show gradual improvements quarter over quarter in 2026. The year-over-year revenue comparison was impacted by a significant Water for Energy delivery in 2025 that did not repeat in the quarter along with the timing of order conversion. We saw strong momentum across several of our priority end markets, including Commercial Pool, Marine, DPF and Membrane, and Plastics.”

“Our strategy focused on reducing reliance on larger, one-off projects and increasing exposure to repeatable, scalable markets,” Chen continued. “Commercial Pool is a strong example of this strategy, with growing customer adoption, increasing order activity, and opportunities to scale across multiple geographies. Based on our order book, we expected a record quarter for commercial swimming pool and continued delivery of marine water treatment systems in Q2 2026. At the same time, our water for industry/energy pipeline remains active, and we continue to expect order activity in 2026. By focusing on markets where our silicon carbide membrane technology offers clear value, while maintaining a disciplined cost structure, we believe LiqTech is well positioned to advance toward durable, profitable growth.”

Q1 2026 Financial Results

Revenue for the three months ended March 31, 2026 was $4.1 million compared to $4.6 million for the same period in 2025, representing a decrease of 10.4%. The decrease was attributable to a reduction in system sales, reflecting a significant Water for Energy delivery in 2025 that did not recur in 2026. Within the Systems segment, sales to both the Pool and Marine segments increased significantly. Furthermore, deliveries of Filters, Membranes, and Components increased during the period.

Gross profit for the three months ended March 31, 2026 was $0.4 million (representing a gross profit margin of 9.5%) compared to a gross profit of $0.1 million (representing a gross profit margin of 2.7%) for the same period in 2025. This increase was primarily driven by mix in system sales, better utilization of our manufacturing capacity, procurement effects on prices, and low depreciation expenses.

Total operating expenses for the three months ended March 31, 2026 were $2.7 million compared to $2.3 million for the same period in 2025. Approximately 60% of the increase relates a 9.9% weakening of the US dollar versus Danish kroner for the three months ended March.

Selling expenses for the three months ended March 31, 2026 were $1.0 million compared to $0.7 million for the same period in 2025. Excluding the impact of foreign exchange developments, costs increased primarily due to the full-year effect of hires within our joint venture in China with JiTRI as well as continued investments in the sales organization across the United States and Europe.

General and administrative expenses for the three months ended March 31, 2026 were $1.4 million compared to $1.4 million for the same period in 2025. Adjusting for FX foreign exchange rates, expenses remained stable and below general inflation, as the hiring of open positions was offset by savings from other overheads. Included in general and administrative expenses were non-cash compensation of approximately $0.2 million for the three months ended March 31, 2026, and 2025, respectively.

Research and development expenses for the three months ended March 31, 2026 were $0.3 million compared to $0.2 million for the same period in 2025. The increase was primarily attributed to membrane development costs and expenses related to the development of Marine systems.

Other expenses for the three months ended March 31, 2026 were $0.4 million compared to other expenses of $0.2 million for the comparable period in 2025. The change was primarily attributable to losses on foreign currency transactions, lower interest income, and accrued interests on the senior promissory notes, partly balanced by lower amortization of debt discount, and a decrease of net interest expenses for the three months ended March 31, 2026.

Net loss for the three months ended March 31, 2026 was $(2.7) million compared to $(2.4) million for the comparable period in 2025.

Adjusted EBITDA (see Table included) for the three months ended March 31, 2026 was $(1.5) million compared to $(1.4) million for the comparable period in 2025.

Cash on hand (including restricted cash) on March 31, 2026, was $2.7 million.

Use of Non-GAAP Financial Measures

In order to provide greater transparency regarding our operating performance, the financial results in this press release refer to a non-GAAP financial measure that involves adjustments to GAAP results. Non-GAAP financial measures exclude certain income and/or expense items that management deems are not directly attributable to the Company's core operating results and/or certain items that are inconsistent in amounts and frequency, making it difficult to perform a meaningful evaluation of our current or past operating performance.

Adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) is defined by LiqTech as net (loss) or income adjusted for (i) taxes, (ii) [other expenses], (iii) depreciation and amortization, (iv) amortization of right-to-use assets, and (v) stock based compensation.

Management believes that the presentation of operating results using this non-GAAP financial measure provides useful supplemental information for investors by providing them with the non-GAAP financial measure used by management for financial and operational decision making, planning and forecasting and in managing the business. This non-GAAP financial measure does not replace the presentation of financial information in accordance with U.S. GAAP. These non-GAAP financial results should not be considered a measure of liquidity and is unlikely to be comparable to non-GAAP financial measures provided by other companies.
