With that, I'd like to turn the call over to Fei Chen, Chief Executive Officer of LiqTech International. Fei, please proceed.

[Fei Chen, CEO at LiqTech International]

Thank you, Robert, and good day to everyone on the call. There is a lot of optimism for the future based on the execution during the third quarter, not simply because of the growth in revenues, improvement in gross margins, and reduction in operating expenses, but also due to the strong order books during the third quarter, which sets the stage for a nice fourth quarter. A key driver during the quarter was the strength within our water treatment systems business, led by our swimming pool vertical, which achieved its highest quarterly revenue to date. Equally important is that the new bookings received during the quarter indicate a continuation of this positive trend. It is clear that the market is increasingly recognizing the unique attributes of our clearer flow filtration system and the compelling alternative it offers to traditional media filtration systems used in commercial pools.

[Fei Chen, CEO at LiqTech International]

Beyond the swimming pool vertical, we are making progress in a number of other applications, which leverage our robust silicon carbon membrane technology, including water for energy, industry applications, and the marine industry. The increased order flow and interest is the direct result of the numerous successful pilot programs we have implemented over the past two years, showing the success of our systems in real-world examples. We have long emphasized that this transformation would take time, and we now believe that we are on the verge of broad adoption of our systems across multiple market verticals. Where system sales are the ultimate measure of success, we have spent considerable effort right-sizing the business and enacting operational efficiencies to drive down costs, both from an OpEx perspective as well as from a manufacturing side.

[Fei Chen, CEO at LiqTech International]

During the quarter, our contribution margin was one of the highest levels we have seen over the past five years, and the gross profit was at 19.6%, also at an improved level. Further, our operating expenses are at their lowest levels in many years. Let me circle back on a few of the key activities during the quarter, starting with the swimming pool vertical. As mentioned, we delivered systems to six customers during the quarter, totaling $1.0 million in revenue. The systems delivered were much larger in size than many of our historical systems, and it really highlights the progress we are making within the larger swimming pool systems. The orders delivered during the quarter were fulfilled through our partners, Banbury and Total Pool in the U.K. and OXIDINE in Spain.

[Fei Chen, CEO at LiqTech International]

These partners have been instrumental to our success, particularly as we have strengthened our collaborations in the past three years. During the quarter, we continued to expand our pipeline within our key markets, including systems in the U.K., Denmark, and Holland. This really shows the depth of what we have accomplished in the past few years building these relationships, but also the internal team's role in helping move projects forward and showcase what is possible with our solutions. Another key development within our swimming pool solutions has been the development of the modular design system, which allows for ease of deployment. Since I took over, we have worked hard to move away from many customized solutions, which often take too long to create and cost too much money. Further, it created too many confusions among customers.

[Fei Chen, CEO at LiqTech International]

This theme of creating a modular design system and driving down costs is not just applicable to our swimming pool vertical, but across other applications as well. To that point, we are working with our joint venture partners in China to reduce the cost of components and assembly of our marine water treatment systems, making them more competitive in the market. We will continue manufacturing the silicon carbon membranes in Denmark. We are also exploring the potential to leverage our Chinese assembly and sourcing capabilities to drive cost reductions across our systems and applications. Another exciting development within our China joint venture has been the reception of two first orders for marine dual-fuel engine water treatment systems. The marine shipping industry is moving towards cleaner, fewer applications, with most new vessels equipped with dual-fuel engines that require reliable water treatment for exhaust gas recirculation systems.

[Fei Chen, CEO at LiqTech International]

According to published data, approximately 400 new vessels are on order with ISO EGR solutions planned between 2024 and 2027. One of the two marine dual-fuel engine orders is scheduled to be delivered here in the first quarter, with the other set for delivery in early 2026. We believe more opportunities are on the horizon. Transitioning from China to the U.S., we have talked about this for a while now, but the water for energy market is rapidly growing within the U.S. We have worked with partners such as Razorback Direct and Renewable Resources lately to build a presence in the U.S. For this reason, we have moved forward with the opening of a dedicated service center near Fort Worth, Texas. The new facility is being launched in partnership with Hydro Systems and opened a few weeks ago.

[Fei Chen, CEO at LiqTech International]

For those not familiar, Hydro is an industry service provider with extensive experience in energy, oil and gas, and industry sectors. They specialize in equipment servicing, maintenance, and field support. The center will strengthen support for our water for energy business segment, offering deployment of certified service technicians, availability of critical spare parts, remote and on-site technical support, and system maintenance and repairs. As we scale our operations in the U.S., this new service center allows us to respond faster and support customers with deep local knowledge and reflects our strategy to offer fully integrated filtration solutions, from engineering and commissioning to lifetime service. On the topic of new system deployments, we are actively engaged with several end customers and hope to have updates to share soon.

[Fei Chen, CEO at LiqTech International]

Taking a step back, I think it is important to remind everyone of the number of new systems that we have deployed during the past couple of years. Since the beginning of last year, we have deployed nine pilots, all commercial systems, across a wide range of industry applications, from multiple oil and gas industry systems to lithium brine production, plastic removal from a U.S. petrochemical company, MEG recovery, metal processing, the broader marine industry, and the most recent order of an advanced membrane-based filtration system to treat oily wastewater to North Star BlueScope Steel, a major U.S.-based steel producer. We are establishing a consistent cadence for large system deliveries each quarter alongside our base business, including swimming pools, plastics, and DPF filters, bringing us closer to revenue levels that approach break-even and profitability. This has been our goal, and I'm very pleased with the progress we have made.

[Fei Chen, CEO at LiqTech International]

Let me now turn the call over to David to review the finance in more details. I will then make a few closing comments and look to open the call for your questions. David.

[David Kowalczyk, CFO and COO at LiqTech International]

Thank you, Fei, and good day, everyone. Let me take some time diving into the financial results in a bit more detail and add some color to what was in the press release. Let's start with revenue. Revenue for the quarter came in at $3.8 million, up from $2.5 million in the year-ago third quarter. Broken down by verticals, sales for the third quarter were as follows: water system sales and related services of $2 million compared to $0.7 million in the same period last year. DPF and ceramic membrane sales were $0.8 million, down from $1.1 million in Q3 last year. Finally, plastics revenue came in at $1.0 million compared to $0.7 million in Q3 last year.

[David Kowalczyk, CFO and COO at LiqTech International]

The key takeaways for the quarter include strong year-over-year improvement in water systems driven by a combination of multiple swimming pool orders and the remaining portion of the industrial order for the steel industry. Growth in plastics, which was up 54% due to a strong external interest within especially food processing and the upgrade of our production facility in Q3 last year, and stabilization of DPF and ceramic membranes sequentially, but still off the year-ago quarter. Looking ahead to Q4 of 2025, we anticipate revenue to be between $4.6 million and $5.6 million, which would equate to a 38%-67% increase from Q4 2024. For the full year 2025, we expect revenue to be between $18 million and $19 million, representing a 23%-30% increase compared to 2024.

[David Kowalczyk, CFO and COO at LiqTech International]

We do want to note that we do want to be cautious and provide a slight change to guidance, solely driven by timing and purchase orders in our systems business. The visibility we have to receive formal purchase orders for two systems during Q4 of 2024 are likely shifting to Q1 of 2026. Turning to gross margin, as we continue to be below our optimal revenue level, we continue to have fixed production costs that are not being fully absorbed and those lower than normalized gross margins. That said, for the third quarter, gross margins were much improved from the year-ago period, coming in at 19.6% compared to a negative margin of 8.5% in the year-ago period. We had previously reported on a contribution margin basis, which excludes the impact from our fixed overhead. This margin for the quarter was significantly higher.

[David Kowalczyk, CFO and COO at LiqTech International]

The gap between gross margin and contribution margin will narrow in the coming quarters, driven by cost improvements and volume growth. Turning to OpEx, total operating expenses for the quarter were $2.1 million compared to $2.4 million in Q3 last year and compared to $2.6 million in Q2 of 2025. As we look to the future, our break-even target measured on an adjusted EBITDA basis, measured at EBITDA adjusted for amortization, right-of-use assets, and cost-to-stock-based compensation, the level continues to be a quarterly revenue of approximately $6 million. The one caveat I will state is that there's a product mix component to it. Concluding on the P&L, net loss was $1.5 million for the quarter compared to a $2.8 million loss for the comparable period of 2025, a substantial improvement driven by revenue growth, improved gross margin, and reduced operating expenses.

[David Kowalczyk, CFO and COO at LiqTech International]

Finally, from a cash perspective, we ended the quarter with $7.3 million in cash. Everything else was very much in line with our normal operating procedures from a balance sheet perspective. With that, let me turn it back to Fei.

[Fei Chen, CEO at LiqTech International]

Thank you, David. Can you hear me?

[David Kowalczyk, CFO and COO at LiqTech International]

Yes, please proceed.

[Fei Chen, CEO at LiqTech International]

Thank you. Okay. Thank you, David. To close things out before I turn the hour to the questions, our preparatory silicon carbon filtration technology stands as a foundational element in tackling the planet's most urgent ecological issues. These cutting-edge ceramic membranes deliver exceptional results in the toughest water treatment scenarios, spanning from produced water in oil and gas operations to pool filtration systems. By helping industries comply with rigorous environmental standards while cutting down on water and energy use, we are resolving vital purification problems and advancing true sustainability. Recent achievements, like landing record orders for swimming pool systems, major contracts for treating produced water, marine applications, and industry applications such as that for the steel industry, highlight the rising worldwide appetite for our innovative solutions. The potential moving forward is immense, fueled by escalating water shortage and tough global regulations.

[Fei Chen, CEO at LiqTech International]

With our key client alliance, we are broadening our impact with application-oriented, ready-to-deploy solutions. Such partnerships enhance our capability to offer complete systems that guarantee regular adherence, streamline operations, safeguard assets, and lower costs for customers. In the years to come, we are dedicated to advancing and expanding our filtration solutions to seize these best possibilities. Again, thank everyone for your support of LiqTech. With that, Robert, we would be happy to take any questions.

[Robert Blum, Managing Partner at LiqTech International]

All right. Fantastic. Thank you very much, Fei and David, for your prepared remarks. Again, to everyone listening on the webcast player there, if you have a question, you can type it into the Ask a Question feature on the player there. We do have a few questions submitted already. We'll begin here. Besides swimming pool systems, which segments are seeing the most sustained order momentum?

[Fei Chen, CEO at LiqTech International]

As mentioned in my speech, we have very much momentum in the water for energy segment as well. We also start getting orders from marine industry. I would say compared to the marine industry, it is just start. The water for energy is getting momentum.

[Robert Blum, Managing Partner at LiqTech International]

Okay. Very good. Next question here. Is the uptick in gross margin sustainable? Where do you see gross margins trending over the next few quarters?

[Fei Chen, CEO at LiqTech International]

David?

[David Kowalczyk, CFO and COO at LiqTech International]

Yes, sure. Thanks for the question. I would say yes, this is very much sustainable. And with expected higher revenues, we will see also further increases in the gross margin. There is a strong link between the size of revenue and really the gross margin. Talking about a defined level, I think it is hard, but we will see increases with increase in revenue.

[Robert Blum, Managing Partner at LiqTech International]

Okay. Very good. Next question here is, how is your capacity utilization trending? Are there any metrics you can provide there?

[David Kowalczyk, CFO and COO at LiqTech International]

Yeah. Obviously, we have different matrices for capacity and also different sites. I think in general, it's fair to say that we have spare capacity, which is also why we provide the insight on the difference between gross margin and contribution margin. We have plenty of capacity to support growth with very, very limited investments.

[Robert Blum, Managing Partner at LiqTech International]

All right. Very good. Again, final reminder here, if you have a question or would like to submit a question through the webcast player, please go ahead and submit that now. Barring any further questions coming in, the last question here is, what would be a reasonable target for 2026 revenue growth?

[Fei Chen, CEO at LiqTech International]

That's a very good question. We're actually in the process of making our budget for 2026, so we cannot say any concrete number yet, but we definitely believe and see a very strong growth trend in 2026.

[Robert Blum, Managing Partner at LiqTech International]

Okay. Very good. I am not showing any further questions at this time. With that, I will turn it back over to you, Fei, for any closing remarks.

[Fei Chen, CEO at LiqTech International]

Thank you, everyone. I would like to thank you all very much for being with us today. We look forward to communicating with you soon again. Thank you.
