Fei Chen, Chief Executive Officer, LiqTech International: Thank you, Robert, and good day to everyone on the call. 2025 represented a meaningful step forward for LiqTech. For the whole year, revenue increased 13%, driven by a 49% increase in total systems and aftermarket revenue, and we made improvements to drive efficiencies across much of our business. That shift toward higher value system sales is central to our long-term strategy and reflects growing adoption of our silicon carbide membrane technology across multiple end markets. While we fell short of our original revenue guidance, this was primarily due to continued delays with a large oil and gas order that remains active in our pipeline. The project is still under discussion, but as we have constantly communicated, the timing of large oil and gas project is difficult to predict. That said, we understand that we cannot run on unpredictable oil.

Our focus needs to be and is on building and diversified systems portfolio with stronger visibility and improved margin profile going forward. In many ways, this has been consistent with our approach since I took over as CEO. To focus on more predictable parts of our business, such as swimming pools, which will be a key driver going forward. We are certainly amplifying this approach going forward in terms of how we allocate our resources. Our commercial pool business was a standout performer in 2025, and it delivered the strongest year in the company’s history. We sold 34 pool systems during the year, a new record for LiqTech. Of those, 24 systems were delivered in 2025, with the remaining 10 scheduled for delivery in early 2026.

Pool system revenue totaled $2.6 million for the year, represented a drive of growth within our systems segment. All systems sold during the year were based on our proprietary QlariFlow commercial pool filtration platform. QlariFlow is designed to meet the increasingly complex operational, regulatory, and space requirements facing modern aquatic facilities. Compared to conventional media filtration, our system delivers stable and reliable water quality, while enabling greater automation and operational efficiency. Its compact and modular design makes it particularly well-suited for retrofit installations, where equipment room space is limited, an increasingly important consideration for operators upgrading aging infrastructure. The record number of system sales reflects growing customer acceptance and increasing confidence among both operators and distribution partners. We see clear momentum as facilities prioritizing water quality, automation, and space efficiency, and QlariFlow is emerging as compelling alternative to traditional filtration methods.

We have also made structural improvements to the pool system itself. Our newer modular design is standardized and cost-efficient, which improves gross margins and simplifies installation. Unlike oil and gas systems, which oftentimes are highly customized to specific customer needs, pool systems are increasingly becoming repeatable off-the-shelf solutions. This makes the market segment both more scalable and profitable. From a distribution standpoint, we recently expanded our relationship with Boundary in the U.K. into an exclusive distribution agreement, subject to minimal annual system volumes. In addition, we are seeing interest from U.S.-based swimming pool companies. In these days, we are working on the final details for the first U.S. swimming pool project. We see potential opening of a very attractive growth market soon. All told, we have sold pool systems in six different countries in 2025, and look to expand that this year.

Based on the guidance we have provided, we expect pool revenue of approximately $5 million-$6 million in 2026, which compares to $2.6 million in 2025, reflecting continued mass adoption and delivery of systems already in backlog. Turning to water for energy, oil and gas remains an opportunity. It continues to create timing challenge. We are engaged with multiple providers, both large and small. The delayed order that impacted 2025 guidance remains under discussion. As mentioned, these systems are typically highly customized, which not only make timing unpredictable, but also impacts our margin profile. Where we continue to pursue this segment and see potential opportunities with partner companies, such as NESR in the Middle East and ongoing trials through Razorback Direct in North America.

We are going to be disciplined in how we allocate resources. We are no longer base our operating plan on difficult-to-predict customer timing, no matter how promised they may be. Where we are seeing encouraging and increasing tangible traction within broader water for industry applications, the successful delivery and commissioning of our advanced membrane-based filtration system for oily wastewater at North Star BlueScope Steel has been a key proof point. The system was designed to resolve recurring filtration disruptions of polymeric membranes caused by high oil content and variability in wastewater quality, which has given our customer costly and difficult experiences. Our system has demonstrated strong performance. This project has reinforced our belief that industrial wastewater treatment can become a larger and more stable contributor to our business.

Industrial systems tend to be more standardized than oil and gas projects, which supports better margin and the shorter sales cycles. We are seeing increased interest across multiple industries, industry verticals. To support this growth, we added dedicated sales resources to expanding our industry presence in the U.S. In further support of our U.S. growth strategy, we also opened a dedicated service center in Texas, in partnership with Halo Systems this past November. This facility enhances our ability to support customers in the water for energy and water for industry segments by providing certified technicians, spare parts availability, remote and on-site technician support, and system maintenance and repairs. Localized service is critical to scaling in the U.S. market. The service center not only strengthens customer support, but has already begun to contribute to new business developments by increasing customer confidence in our long-term commitments to the region.

Going ahead, we believe we will see strong contribution from industry side of broader energy segment, with upside opportunities from the more specific oil and gas markets. In total, we are expecting water for energy, water for industry-related revenue of $5 million-$8 million. This compared to $4.1 million for this market segment in 2025. We are happy to see that our marine segment is building momentum, particularly through our joint venture in China. During 2025, we broke ground on a new marine-focused R&D sales center and the localization facility in Haimen, Nantong. Completed a regional spare parts warehouse to strengthen service capabilities for our growing marine customer base.

These investments are designed to support the development and localization of marine silicon carbide membrane water treatment units for dual-fuel engine vessels on board with water purification and reuse. By increasing local assembly and sourcing within China, we are improving supply chain resilience and cost competitiveness in the market. We strongly believe that silicon carbide membrane technology will continue gaining adoption in new marine vessels equipped with dual-fuel engine, driven by its durability, chemical resistance, and energy efficiency. We ended the year with three marine orders for eight commercial vessels in backlog, scheduled for delivery throughout 2026. Marine revenue, including service sales, was approximately $1.5 million in 2025, and we are targeting approximately $4 million in 2026, reflecting a good market adaptation of our membrane filtration technology.

Look at the broader system business, including pool, water for energy, water for industry, and the marine side. Our expectation is that we will generate revenue of $14 million-$18 million. This would be up from $8.2 million in systems revenue in 2025, showing growth of about 70%-120%. This is a key reason why we are so excited about the future. Beyond our systems business, we also have our legacy DPF and membrane business, and the plastic business, which remains a stable contributor to our operations. Combined, these segments represented approximately $8 million in revenue in 2025. We expect this part of our business to remain reasonably stable in 2026, and in a caution outlook, are anticipating total revenue from the two groups combined to be slightly increased to $9 million in revenue.

Looking at 2026, we expect revenue in the range of $23 million-$27 million, a positive full year 2026 Adjusted EBITDA in the middle to high range of the revenue guidance, assuming constant currency. Growth is expected to be driven primarily by continued expansion in pool systems, industry applications, and marine. The range in our revenue guidance largely reflects the continued unpredictability of oil and gas project timing. Our strategic focus remains clear: scale, standardized, higher margin system platforms. We are maintaining disciplined cost control and operational efficiency with the goal of near-term profitability. 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 Kowalczyk, Chief Financial Officer and Chief Operating Officer, LiqTech International: Thank you, Faye, 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. Please note that I will keep my remarks focused primarily on the year-over-year changes. Let’s start with revenue. Revenue for the year came in slightly above $16.5 million, up from $14.6 million a year ago. Broken down by verticals, sales for the year were as follows: systems and aftermarket sales of $8.2 million, compared to $5.5 million in the prior year. DPF and ceramic membrane sales were $4 million, down from $5.6 million in the prior year. Finally, plastic components revenue came in at $4.1 million, compared to $3.4 million last year.

The increase was mainly due to increased deliveries of systems, so pool, energy, industry, and marine water treatment, and components in plastics, partly offset by decreased sales of filters. The increase in deliveries of system was mainly driven by increased deliveries within pool filtration and industry systems. The increase in components, mainly within machine building for food industry. The decrease in sales of filters was primarily driven by a refocusing of our strategy to capitalize on sub-segments where we see increased due to demand for DPF outside automotives. As Faye mentioned, the delta between our recent expectations for 2025 and actual result is primarily due to the delay in a larger oil and gas system, which remains in our pipeline, but we have not yet received the purchase order for. Turning to gross margins.

Margins for the year were 7.6%, compared to 1.7% in 2024. 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. A couple of key notes is that part of the increase in gross margins was due to the higher level of overall revenue, as our contribution margins are typically on average in the 40% area, but we do have some fluctuations between market segments, as you know. This was offset by the investment of resources into deliveries of containerized oil and gas systems to the U.S., which contributed to lower than usual margin, reflecting a strategic decision aimed at demonstrating the validation of our value proposition associated with our technology and seeding the market for future growth.

As we move forward, a key focus will be on leveraging our standardized systems, which inherently are higher margin. This means more focus on pools, industrial applications, marine applications, and membrane sales. Turning to OpEx, total operating expenditures for the year were $9.6 million, compared to $9.7 million last year. Breaking it down, selling expenses for the year were $2.7 million, compared to $2.7 million last year. This development was partly driven by full year effects of savings made in 2024, and lower consumable write-offs and provision needs. These effects were partly offset by costs associated with our newly formed joint venture in China, cost for outbound distribution, including tariffs to the US, and expenditures related to external sales consultancy services, which also increased in 2025.

General administrative expenses for the year ended December 2025, were $5.7 million, compared to $5.7 million in 2024. The underlying development in local currencies, Danish crowns, was a 4% improvement compared to 2024. This development was due to savings made in 2024, partly balanced by filling the CFO position and other open positions. Research and development expenses for the year was $1.2 million, compared to $1.4 million in 2024. The decrease was primarily due to a more focused R&D strategy, with fewer ongoing projects and reduced average number of employees engaged in external research and development activities. For the year, Adjusted EBITDA was negative $5 million, compared to negative $6.1 million last year. Turning to our guidance.

For 2026, we are expecting revenue to be in the range from $23 million-$27 million. As we break this down, we are anticipating that our broader water for energy and water for industry business will be between $5 million and $8 million. We believe our pool business will be in the range of $5 million-$6 million. Our marine business will be about $4 million, of which 60% will be from new systems and 40% from our recurring service business. Finally, that our legacy DPF and plastics business will be about $9 million. We target a positive full year 2026 EBITDA in the mid to high range of the revenue guidance, assuming constant currencies. Finally, from a cash perspective, we ended the quarter with $5.1 million in cash.

Everything else was pretty much in line with our normal operating procedures from a balance sheet perspective. With that, let me turn it back to Fei.

Fei Chen, Chief Executive Officer, LiqTech International: Thank you, David. To close things out before I turn over to questions, our silicon carbide filtration platform is central to how we address increasingly complex global water challenges. Built on advanced ceramic membrane technology, our solutions are designed to operate reliably in some of the harshest and most demanding treatment environments, from produced water in energy application to commercial pool systems and heavy industry wastewater streams. By helping customers meet strict environmental regulation, we are lowering water usage and energy intensity. We provide practical, high-performance solutions that support long-term sustainability goals. The momentum we generated in 2025, including record pool system sales, progress in produced water, marine system deployment, and industry installations, such as our project with a major steel producer.... demonstrates the expanding global recognition of our technology’s value. As we look ahead, our direction is well defined.

We are prioritizing growth in our most attractive verticals, particularly foods, industry applications, and marine. We are remaining disciplined execution across the organization. At the same time, we remain firmly focused on scaling the business to achieve profitability and positioning LiqTech for durable, profitable growth over the long term. Again, thank everyone for your support of LiqTech. With that, Robert, we would be happy to take any questions.

Robert Blum, Moderator, Lytham: All right. Thank you very much, Fei and David, for those prepared remarks. I want to remind everybody that is listening to the webcast player, to ask a question, simply type in your question through the Ask a Question feature in the player there, we’ll do our best to get to as many questions here as possible. There are a few already in the queue here, Fei and David. The first one here is: When can we expect revenue from the large oil and gas order push-out to be booked?

David Kowalczyk, Chief Financial Officer and Chief Operating Officer, LiqTech International: That’s a good question. Of course, as we mentioned, it’s a bit, you can say, in the hands of the customer, but we definitely would expect, you can say, the oil and gas project to materialize in the coming, in this year, essentially 2026, with the timing of. Yeah, we don’t know the precise timing, but Q2 finalization, ideally.

Robert Blum, Moderator, Lytham: Okay, very good. The next question here is: Do tariffs affect your U.S. oil and gas business? Are your products competitively priced?

Fei Chen, Chief Executive Officer, LiqTech International: This is a very good question because the tariffs is a moving target, so we really have our focus on that. Up to now, we have been able to kind of have very good discussion with our customers, so we don’t really need to take all the tariffs on ourself alone. Going forward, we’re definitely looking at what is the best way for us to handle the tariffs and, you know, how we’re able to keep our competitiveness. As we mentioned before, we are working very focused on the cost reduction of our product and also the standardization and efficiency, and that will somehow balance also to the tariff impact on our technology.

Robert Blum, Moderator, Lytham: Okay, very good. Again, quick reminder to everyone, simply type your question into that Ask a Question feature in the webcast player, if you do have any questions here. A couple of questions here pertaining to your need, for capital here in 2026.

Fei Chen, Chief Executive Officer, LiqTech International: As you have heard today, we actually have laid out a very clear growth plan, with a revenue guidance of $23 million-$27 million in 2026. We are definitely evaluating how we’re able to support this strong growth plan, and that means we are looking at different financial options.

Robert Blum, Moderator, Lytham: Okay, very good. Looks like this may be the final question, barring any last minute that may come in. I think you’ve touched on this a few times, but to reiterate, what are the drivers of your 2026 revenue outlook of $23 million-$27 million?

Fei Chen, Chief Executive Officer, LiqTech International: This is a very good question also, as we use some time in our earnings call about this. What we really have to say to ourselves is we have to make really focus on the broader and diversified perspective, and also working more on the verticals, which are more, which have more visibility and higher predictability. We’re actually working at the growth in basically all our system segments. The pool system, we’re going to have $5 million-$6 million coming this year, and the marine grow from $1.5 million-$4 million. We said, water for energy and water for industry will be $5 million-$8 million. There’s a bigger range there, because the oil and gas projects are more difficult to predict the timing.

The DPF and plastic, plus the membrane area, we expect a slight increase from 8 million to 9 million. As you can hear now, the drive is from the different verticals, and this give us much more reliable, predict revenue growth compared with before.

Robert Blum, Moderator, Lytham: Okay, very good. I’m showing no further questions in the queue. With that, I would like to turn the call back over to Fei Chen for closing remarks.

Fei Chen, Chief Executive Officer, LiqTech International: Thank you, Robert. I would like to say thank you to all of you for being with us today. We look forward to communicating with you soon again. Thank you.

Drew, Conference Specialist: The conference has now concluded. Thank You for attending today’s presentation. You may now disconnect.
