Summary

LiqTech International (NASDAQ:LIQT) reported a 10.4% revenue decline resulting from a non-recurring prior-year water for energy project, while core commercial pool, marine, DPF, and plastic businesses demonstrated growth. Management reiterated the full-year revenue guidance of $23 million to $27 million and emphasized its shift toward scalable, repeatable systems that boost gross margin and predictability. Expense increases were most pronounced in sales and R&D, reflecting targeted hiring and development in higher-conviction growth areas, with currency translating to higher reported costs. The strategic entry into the US pool market and recent large international orders establish new, diversified pillars for revenue, while backlog and pipeline conversion timing will drive quarterly results.

• Gross profit increased despite lower revenue, signifying effective cost controls and business mix improvements during the period.
• Commercial pool systems now address both retrofit and new-build opportunities, reducing dependence on any single project type or region.
• Order book strength in pool and marine, supported by key partnerships and a growing US presence, is expected to drive a record quarter for commercial swimming pool in quarter 2 2026.
• Disciplined approach to oil and gas vertical means revenue growth is distributed across multiple sectors, minimizing concentration risk.

Now I would like to turn the call over to Fay Chen, CEO of LiqTech International, Inc. Fei, please proceed.

Fei Chen: Thank you, Robert. And good day to everyone on the call. The fourth quarter was in line with our expectations. And represented a continued step forward in the transition we have been describing over the past several quarters. Our focus remains on building a more balanced, repeatable, and ultimately more profitable. By placing greater emphasis on the markets where our technology delivers, clear value and where customer adoption can scale in a more predictable way. The year over year revenue comparison was impacted by a significant water for energy delivery in 2025. That did not repeat in 2026. As well as timing of order conversion. However, the underlying activities across the business were encouraging.

Commercial pool marine, DPF, and the membrane all showed meaningful activity in the quarter. And the new pool and marine orders are setting the stage for improved results. In the second quarter and throughout 2026. Compared to Q4 in 2025, our revenue increased by 32% Our gross margin expanded by roughly 1.29 thousand basis points. The nature of our business and the sales cycle time means that all the improvements we have made in 2025 will ensure gradual improvements quarter-over-quarter in 2026. We are, therefore, reiterating our full year 2026 outlook for revenue of $23 million to $27 million. David will go through the financial details in a few minutes.

So I will focus on operating progress customer activity, and the strategic direction. The main message is that our strategy is advancing. We are building around a portfolio of opportunities where our silicon carbide membrane technology can be deployed in repeatable platforms supported by stronger service capabilities and scaled across geographies. Our commercial pool business continues to be 1 of the clearest examples of this strategy. During the first quarter, pool delivery totaled revenue of $800 thousand compared to $300 thousand in the first quarter 2025. More importantly, the order activity we have announced since the beginning of the year reinforces our confidence that ClariFlow is getting traction as a differentiated solution for modern commercial aquatic facilities.

In fact, based on our order book, we expect a record quarter for commercial swimming pool in quarter 2 2026. A key milestone was our first US pool system order consisting of 3 systems, to be installed at the Weston County School District Number 1 Aquatic Center, in Newcastle, Wyoming. Entering the US market has been an important objective for us. Because it is a large market with aging infrastructure high water quality expectations, and a growing need for more automated and space efficient filtration solutions. We view this first US order as an important proof point that can help open additional opportunities over time. We also received consecutive record-setting pool system orders internationally.

1 was in partnership with Lotte for a new large scale commercial pool project in the Netherlands. The next was the follow on record order in partnership with Verdical Limited. for 10 systems for Plumpton Aquatic and the Leisure Center in Fraser Rise Victoria, Australia. These wins demonstrate that our solution is being adopted across different geographies, project types, and the partner channels. ClariFlow is well suited to this market because it addresses several customer needs at the same time. Our systems are compact. Modular, and designed for stable water quality, automation, and efficient operation. For retrofit projects, the smaller footprint can be a meaningful advantage. Where equipment room space is limited.

For new build facilities, the modular design gives customers a flexible solution that can be planned into the project from the beginning. From a business model perspective, pools are attractive because the systems are becoming more standardized and repeatable. This is different from large 1-off projects. Which often require more customization and can be more difficult to forecast. As pool adoption grows, we believe this vertical can contribute to better revenue visibility, improved execution, and a stronger margin profile. Over time. Our marine business also continued to build momentum in the first quarter. We delivered 2 systems during the quarter for marine dual fuel engine water treatment for LNG vessels.

And we expect 2 more systems to be delivered during the second quarter. Marine revenue totaled $800 thousand in the first quarter compared to $200 thousand in the first quarter 2025. The growth in this vertical is being supported by our joint venture in China. Which we believe can help drive more sustainable order flow throughout 2026. As we discussed on our last call, we have invested in local capabilities to support the marine market, including development and localization activities and regional service infrastructure. This is important because the marine market requires reliable execution, responsive service, and a cost competitive localized supply chain.

We believe silicon carbide membrane technology has a strong fit in marine applications particularly for vessels equipped with dual fuel engines. These vessels require advanced water treatment solutions that can support onboard wastewater purification and reuse, while meeting demanding operating requirements. Marine is also attractive because it has the potential to become more repeatable as adoption grows. Each vessel project has its own delivery schedule. But the underlying system platform can be standardized and supported through our regional presence. Turning to water for energy and industry applications. Our view remains balanced and disciplined. Oil and gas continue to be an opportunity for LiqTech. And our pipeline remains active.

At the same time, as we have said before, the timing of larger projects can be difficult to predict. During the quarter, we commenced a new pilot program in West Texas for produced water stream treatment with the energy services and solutions company. This type of field activity is important because it gives customers the opportunity to validate the performance of our technology in demanding operating conditions prior to their investment decision for large sized commercial projects and it allows us to further demonstrate value proposition of silicon carbide membranes in produced water treatments. We continue to believe our technology is well positioned for difficult water streams, where durability chemical resistance, and a stable filtration performance are critical.

Produced water and industry wastewater are both areas where customers are looking for solutions that can handle high variability reduce operational disruptions, and support environmental and the water reuse objectives. At the same time, we are being careful in how we allocate resources. We are not basing our operating plan on the timing of any single large oil and gas project. We will continue pursue attractive opportunities, but we will do so in a way that supports the broader strategy of building a more balanced business. Beyond systems, our DPF and the membrane business and our plastic business, remain important contributor to LiqTech.

In the first quarter, DPF and the membrane revenue increased to 1.3 million from 1 million in the prior year quarter. This was driven by strong order flow from both existing and the new customer following our renewed focus within this marked vertical. Plastic revenue increased approximately 5% in the quarter and totaled about 1 million driven by strong external interest especially in food processing. Looking ahead, our priorities are clear. We are reiterating our 2026 outlook and remain focused on executing against the revenue growth and the adjusted EBITDA improvement we have communicated. The path to achieving this outlook is not depending on a single large oil and gas order.

It is based on continued progress across commercial pool, marine industry application, and the components market with potential upside from water for energy as opportunities convert. The most important strategic priority is to improve the quality of our growth. Max, where solutions can be standardized partners can extend our reach, service infrastructure, support customer confidence, and the volumes can support better margins. We believe the first quarter provide encouraging evidence that this transition is working. Pool orders are expanding geographically Marine deliveries are increasing, supported by China JV, DPF, and the membrane is benefit from renewed commercial focus. and water for energy remains active, but we are approaching it with appropriate discipline.

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

David Nørby Foss Kowalczyk: Thank you, Fei, and good day, everyone. Let me take some time to walk through our first quarter financial results in a bit more detail and add some color to what was included in the press release. As Fay noted, the quarter was generally in line with our expectations. The expectations we provided in our year end call. My remarks today will focus primarily on the year over year changes. For the first quarter and on how those results fit into the full year outlook that we are reiterating today. Let's start with revenue. Revenue for 2026 was $4.1 million. Compared with 4.6 million in 2025. This represents a decrease of 10.4%.

Broken down by verticals sales for the year were as follows. Systems and aftermarket sales were 1.8 million compared to 2.7 million in the prior year quarter. DPF and membrane sales were 1.3 million compared to 1 million in the prior year quarter. And finally, plastic components revenue was 1 million compared to approximately 1 million in 2025. The year over year revenue decline was solely attributable to lower system sales. Specifically the fact that we had a significant water for energy delivery in the 2025. did not repeat in the 2026. That comparison is important. Because the underlying activity in several of our priority areas was stronger than the headline revenue number might suggest.

Within systems, both commercial pool and marine showed meaningful improvements. Commercial pool revenue was approximately $800 thousand for the quarter, compared with approximately $300 thousand in the prior year quarter. Marine revenue was also approximately $800 thousand compared with approximately $200 thousand in 2025. Those increases were offset by the non-repeat of the larger water for energy delivery last year. Outside of systems, DPF and membrane sales increased meaningfully driven by strong order flow, from both existing and new customers. Following our renewed focus within that market vertical. Components also increased during the quarter. Supported by continued external interest especially within food processing.

These are important contributors because they provide a more stable base for recurring activities while we continue to scale the high growth system opportunities. Turning to gross margins. Gross profit for the quarter was $400 thousand representing a gross margin of 9.5%. That compares to a gross profit of $100 thousand or a gross profit of 2.7% in 2025. The improvement in gross margin is an important point. Even though total revenue was lower year over year, our gross profit dollars actually increased. And our gross margin expanded by roughly 280 basis points. The improvement was primarily driven by mix in system sales better utilization of our manufacturing capacity, procurement efforts on prices, and lower depreciation expenses.

As we have discussed before, we are still operating below the level of the revenue. Where our production platform can fully absorb fixed costs. As a result, our gross margin is not yet where we believe it can be over time. That said, the first quarter shows the benefit of improving mix. Continued operating discipline and greater focus on repeatable applications where our cost structure and system design become more efficient as volume increases. Gross margin improvement remains a key priority. Scaling standardized systems in commercial pool and marine along with continued strength in our component business should help support a better margin profile as we move through 2026. Turning to operating expenses.

The total operating expenses for the first quarter were $2.7 million. Compared to 2.3 million in 2025. Approximately 60% of this increase was related to foreign exchange development. Of course, the majority of our cost base is denominated in Danish kroner or euros. The year over year currency movement affected how expenses translate into U. S. Dollars. Breaking operating expenses down by category, Selling expenses for the first quarter were 1 million compared to $700 thousand in the prior year quarter. Excluding foreign exchange effects, the increase was primarily related to the full year effect of hires within our Chinese joint venture as well as continued investment in the sales organization across the United States and Europe.

General and Administrative expenses were 1.4 million compared to 1.4 million in 2025. Adjusting for foreign exchange development, G&A expenses remained stable and below general inflation. We continue to manage overhead carefully, and the filling of open position was balanced by savings in other areas. Research and development expenses of $300 thousand compared to $200 thousand in the prior year quarter. The increase was primarily tied to membrane development costs, development work related to marine systems. Overall, our approach to operating expenses remains disciplined. We are investing where we see clear commercial returns particularly in sales coverage, marine development, and capabilities that support the scaling of repeatable system platforms.

At the same time, we are carefully managing overhead and focusing resources on the areas of the business that are most important to our path towards profitability. Other expenses for the quarter were $400 thousand compared to other expenses of $200 thousand in the comparable period for 2025. The change was primarily attributable to losses on foreign exchange transactions due to the US dollar development compared to euro, Lower interest income and accrued interest on the senior promissory note, partly balanced by lower amortization of debt discount and a decrease of net interest expenses. Net loss for the 2026 was DKK 2.7 million, compared to a net loss of DKK 2.4 million in 2025.

The year over year change was primarily driven by the higher operating expenses, and other expense levels that I just discussed. Particularly offset by the improvement in gross profit. For the first quarter, adjusted EBITDA was a negative 1.5 million compared to a negative 1.4 million in 2025. While the year over year comparison was relatively stable, we continue to believe the most important drivers of adjusted EBITDA improvements are revenue scale. Stronger system mix, and increased utilization, disciplined operation expense control. We are making investments in targeted areas but our objective remains to convert revenue growth into meaningful operating leverage as the year progresses. Turning to our outlook.

We are reiterating our expectations for the full year of 2026 revenue to be in the range of $23 million to $27 million This would represent a growth of approximately 39% to 64% compared to full year 2025. As we discussed, the growth outlook is expected to be driven primarily by commercial pool, marine, and continued activity across water for energy and in industrial applications. Supported by stable contributions from DPF and membranes, and plastic components. We expect improved pool results in the second quarter and through 2026. Supported by recent order activity including the first US pool system order and additional larger international pool projects.

In marine, we delivered 2 systems during the first quarter and expect 2 more systems to be delivered during the second quarter. With further sustainable order flow expected through the year. Supported by our Chinese joint venture. The quarterly cadence of revenue will continue to be influenced by system and delivery times. As a result, we do not view the first quarter as a full year indicator. We remain focused on executing against backlog converting the order pipeline, and maintaining cost discipline as the business scales. And finally, from a cash perspective, we ended the first quarter with cash on hand, including restricted cash, of 2.7 million as of March 31, 2026.

Our focus remains on disciplined cash management, and careful allocation of resources. We are aligning spending with the verticals that we believe can support repeatable growth improved margin performance, better revenue visibility over time. As we move through 2026, we will continue to balance investments in growth, with the need to preserve flexibility and drive the business towards positive adjusted EBITDA. And with that, let me now turn the call back to Fay.

Fei Chen: Thank you, David. Before we open the call for questions, I want to reiterate that our first quarter results were in line with our expectations and reflect continued progress against our strategic plan. We are building LiqTech around end markets that can support more predictable, repeatable growth. Particularly commercial pool, marine, DPF membrane, and plastic components. We believe the results in this year will continue to highlight this transition. At the same time, we remain encouraged by the long term opportunity in water for energy. But we are being disciplined in how we plan the business and allocate resources. Our focus is on markets where our silicon carbide technology delivers clear, performance advantages and where we can scale profitably.

With that, With that, Robert, we would be happy to take any questions.

Robert Blum: Thank you very much, Fei and David, for your prepared remarks there. As a reminder to everyone listening through the webcast portal there, if you would like to ask a question, you can type it into the ask a question feature on the webcast player. We do have a few questions already in the queue here. So, Fay and David, I will begin. First question here is what does a quote steady state margin structure look like for the new LiqTech? How should we model gross margins?

David Nørby Foss Kowalczyk: Yes, that is a good question. So, essentially, what we have told before and what we you can say continue to see is that on a project basis, we are realizing margins between 30% to 50%. So, essentially, you can see on average 40%. With the volume increase, we should be closing in on a steady state margin of 40%. Of course, on top of that, with the volume increase, you will see additional scaling effects. Leaving, you can say, opportunity open. For lowering the production cost further for systems and membranes.

Robert Blum: Okay. Very good. There are a few questions here regarding guidance for the year, so I will try to combine them together. You are guiding revenue of $19 million to $23 million. For the rest of the year here, which implies 6.3 million to 7.6 million per quarter. What are the major drivers of this revenue growth and how much does water for energy or industry contribute to this revenue?

Fei Chen: Robert, that is a very good question. Your number is correct. And the first quarter, we do not have very much contribution from water energy and water industry. But we do have a pipeline with some very interesting projects with high probabilities. Should we expect in the year going forward, we will see some project go through. From these 2 areas, water for energy and water for industry. But very importantly, also, we see really significant growth in our commercial pools, marine, and also DPF and the membrane. For the rest of the year. So this whole together, will contribute to the increase quarter-by-quarter.

Robert Blum: Okay. Very good. And as a sort of extension of that, do you have any information you could provide relating to how revenue will be distributed between Q2, Q3, and Q4.

David Nørby Foss Kowalczyk: Yes. So we definitely and as we said, you can see also in the presentation, the result we expect the implementations of, you can say, changes in how we operate in 2025. Show gradual improvements through 2026. We definitely do expect to see a gradual ramp up. Also with the Q2, you can see increase compared to Q2. For the commercial pool to be a record quarter on revenue because there is a time difference.

Fei Chen: Between the commercial order and the revenue conversion. And that is, you know, always make it complicated. When the revenues come in. But we have a very strong order book. So we can really see what is happening next quarter.

Robert Blum: Alright. Very good. Again, as a reminder, if you would like to ask a question, feel free to type it into the ask a question feature on the webcast player. And if there are any follow ups that need to be, submitted, please send those along as well. Next question here is regarding commercial pools. The order that you highlighted in the Netherlands is for a new pool. This person's understanding is that you focused on retrofits. Is new sales a new opportunity for the company?

Fei Chen: that is a very, very good question. I mean, 2 years ago, I think our pool system has been very much focused on the retrofit. it is very much depends on the distributors. Because at that time, our distributor in UK was Total Pool. Their focus was and still is retrofit. Swimming pools. And now we have start building up the new distributors both in UK with B&Nry, and also with Lotte. They are the ones really very active both on the retrofit and the new project. So now we see the new project also coming.

So I would like to emphasize we are actually working both on the retrofit and the new pool new build pools because our system has really strong advantages for both segments.

Robert Blum: Alright. Very good. I am showing no further questions in the queue here. So with that, Fay, I will turn it back over to you for closing remarks.

Fei Chen: Thank you, Robert. Thank you all very much. For being with us today. We look forward to communicating with you again soon.
