Teleconferência de Resultados do 2º Trimestre Fiscal de 2026 da LiqTech (LIQT): Corte nas Projeções

A LiqTech International (LIQT) relatou receita e lucratividade menores no segundo trimestre fiscal de 2026, com os ganhos nos segmentos de Piscinas Comerciais e Marítimo sendo compensados pela menor atividade de Água para Energia e por restrições de produção. A administração revisou sua projeção de receita para todo o ano após o adiamento de um grande projeto de Água para Energia.

Principais destaques

• A receita no segundo trimestre fiscal de 2026 diminuiu 12% em comparação ao mesmo período do ano anterior, caindo para US$ 4,4 milhões, enquanto a margem bruta recuou de 9,8% para 8,4%.
• O prejuízo líquido aumentou de US$ 2,2 milhões para US$ 3,1 milhões. O EBITDA ajustado ficou negativo em US$ 1,6 milhão, em comparação ao valor negativo de US$ 1,3 milhão registrado no mesmo período do ano anterior.
• A receita do segmento de Piscinas Comerciais atingiu o recorde de US$ 1,5 milhão, ante US$ 0,8 milhão registrados tanto no segundo trimestre fiscal de 2025 quanto no primeiro trimestre fiscal de 2026. A receita do segmento Marítimo aumentou de US$ 0,4 milhão no mesmo período do ano anterior para US$ 0,7 milhão.
• A administração revisou a projeção de receita para todo o ano fiscal de 2026 para a faixa de US$ 20 milhões a US$ 23 milhões, após um grande cliente de Água para Energia reiniciar partes de seu processo interno de avaliação e aprovação na sequência de uma mudança organizacional.
• Uma oferta pública realizada em junho gerou cerca de US$ 18 milhões em recursos líquidos. A LiqTech encerrou o trimestre com US$ 15,7 milhões em caixa, incluindo caixa restrito, e eliminou suas notas promissórias sênior restantes e notas de desconto de emissão original.
• A LiqTech obteve um pedido complementar de US$ 2,1 milhões para quatro sistemas industriais de filtragem de águas residuais de uma fabricante de aço sediada nos EUA. Espera-se que cerca de 75% do pedido seja entregue até o final de 2026.

Principais dados financeiros

Desempenho Operacional e dos Negócios

Piscinas Comerciais

O segmento de Piscinas Comerciais foi o negócio mais forte da LiqTech no trimestre. A receita atingiu o recorde de US$ 1,5 milhão, em comparação com US$ 0,8 milhão tanto no mesmo trimestre do ano anterior quanto no trimestre anterior.

A empresa concluiu a montagem do projeto Plumpton Aquatic and Leisure Centre na Austrália e seu primeiro projeto de piscina comercial nos EUA, em Worland, Wyoming. Um grande sistema em Den Helder, Países Baixos, está operando com sucesso. A administração continua a expandir as relações de distribuição com base na plataforma padronizada e modular QlariFlow.

Marítimo

A receita do segmento Marítimo subiu para US$ 0,7 milhão, ante US$ 0,4 milhão no ano anterior, mas diminuiu em relação aos US$ 0,8 milhão registrados no primeiro trimestre fiscal de 2026. A LiqTech obteve a aprovação no teste de aceitação de fábrica para suas duas primeiras unidades de tratamento de água dual-fuel iCER.

A administração espera entregar uma unidade iCER adicional e dois sistemas marítimos de tratamento de água para depuradores de gases no terceiro trimestre fiscal. A empresa também recebeu um pedido de quatro sistemas de tratamento de água para embarcações equipadas com EGR na China, com a primeira entrega prevista para dezembro.

Água para a Indústria

A LiqTech recebeu um pedido complementar de US$ 2,1 milhões de uma fabricante de aço sediada nos EUA para quatro sistemas adicionais de filtragem de águas residuais. O pedido ocorreu após cerca de 10 meses de operação estável do sistema inicial do cliente.

A empresa também recebeu um pedido de um novo cliente norte-americano para um sistema de filtragem por membrana cerâmica QureFlow QF-6 em uma instalação em Freeport, Texas. O sistema tratará águas residuais da limpeza de equipamentos industriais e reciclará a água tratada para o suprimento de água de lavagem da fábrica.

A administração planeja direcionar mais recursos para aplicações industriais selecionadas, onde as necessidades dos clientes, o alinhamento da tecnologia e a visibilidade de receita no curto prazo sejam mais fortes.

Água para Energia

Um cliente de grande porte passou por uma reestruturação organizacional, trazendo novos tomadores de decisão para um projeto importante de Água para Energia. Partes significativas do processo de avaliação e aprovação do cliente tiveram que ser reiniciadas.

A administração afirmou que o projeto permanece ativo, o relacionamento com o cliente está intacto e os resultados técnicos continuam atraentes. No entanto, aprovações mais lentas e prazos de entrega mais longos para equipamentos críticos reduziram o montante de receita relacionada incluído na projeção para 2026. A LiqTech pretende atuar nesse mercado de forma mais seletiva e, cada vez mais, por meio de parcerias comerciais estratégicas.

DPF, Membranas e Plásticos

A receita de DPF e membranas recuou para aproximadamente US$ 1,0 milhão, ante US$ 1,3 milhão no mesmo período do ano anterior e no primeiro trimestre fiscal de 2026. A administração atribuiu o declínio principalmente a atrasos temporários na produção causados pela disponibilidade restrita de uma matéria-prima crítica.

A receita do segmento de Plásticos foi de aproximadamente US$ 0,9 milhão, em comparação a US$ 1,2 milhão no segundo trimestre fiscal de 2025 e a cerca de US$ 1,0 milhão no trimestre anterior. Decisões de compra mais lentas por parte dos clientes e a incerteza no mercado de matérias-primas pesaram sobre o negócio.

Projeções da Administração

A LiqTech revisou sua projeção de receita para todo o ano de 2026 para entre US$ 20 milhões e US$ 23 milhões. A alteração reflete principalmente o adiamento das atividades no segmento de Água para Energia que deveriam contribuir ao longo de 2026.

A perspectiva pressupõe a continuidade da solidez em Piscinas Comerciais e Marítimo, oportunidades selecionadas em Água para a Indústria e contribuições constantes de DPF, membranas e plásticos. Espera-se que cerca de 75% do novo pedido de US$ 2,1 milhões no setor siderúrgico seja entregue até o final do ano.

A administração identificou o cronograma dos pedidos de sistemas maiores como a principal variável. Espera-se também que o ritmo revisado de receita atrase a alavancagem operacional. As prioridades declaradas da LiqTech continuam sendo a melhoria da margem bruta, o controle rigoroso dos gastos, a gestão do capital de giro e o alcance da lucratividade o mais rápido possível.

Riscos e Pontos de Atenção

• Os ciclos de vendas do segmento de Água para Energia exigem testes, validação técnica, aprovações de clientes e orçamento de capital, tornando o cronograma dos projetos difícil de prever.
• Mudanças organizacionais em clientes e processos longos de aprovação podem transferir receitas expressivas de sistemas entre períodos fiscais.
• A receita permanece abaixo do nível necessário para absorver totalmente os custos fixos de produção, limitando o desempenho da margem bruta.
• Restrições em matérias-primas críticas prejudicaram a produção de DPF e membranas durante o trimestre.
• As variações cambiais aumentaram as despesas operacionais reportadas, pois uma parcela significativa da base de custos da LiqTech é denominada em coroas dinamarquesas e euros.
• A demanda por plásticos foi afetada por decisões de compra mais lentas e pela incerteza em relação aos preços das matérias-primas.

Destaques da Sessão de Perguntas e Respostas

A administração declarou que as iniciativas de lucratividade no curto prazo incluem a padronização de produtos entre os segmentos Marítimo, Piscinas Comerciais e Água para a Indústria; a melhoria nos processos de compras; o suprimento de componentes selecionados por meio da joint venture na China; a otimização de estoques; e o aumento da eficiência de produção e do controle de qualidade.

Sobre o QureFlow, a administração destacou o revestimento patenteado nas membranas de carboneto de silício da LiqTech e a operação em fluxo cruzado contínuo do sistema. O primeiro sistema do cliente do setor siderúrgico operou por 10 meses antes do pedido de quatro unidades adicionais.

No segmento de Piscinas Comerciais, a administração afirmou que o crescimento decorre tanto de maiores volumes de unidades quanto de sistemas de maior porte. Espera-se que o primeiro sistema de piscina nos EUA seja instalado até o final do terceiro trimestre fiscal de 2026.

Para o segmento Marítimo, a LiqTech espera que parcerias para montagem terceirizada na China garantam capacidade flexível. A empresa está focada em padronizar os sistemas iCER, EGR e depuradores de gases para dar suporte a uma produção mais rápida à medida que os pedidos aumentarem.

Fei Chen

Thank you, Robert, and good day to everyone on the call. Before discussing the quarter, I want to acknowledge an important development for LiqTech and our shareholder base. In June, we completed an underwritten public offering that generated approximately $18 million in net proceeds. The offering brought a number of new shareholders into LiqTech. And I want to thank those investors along with our existing shareholders for the confidence you have placed in our company and our technology.

We recognize the rising equity capital comes with significant responsibility to our shareholders. We expect to be judged by how effectively we deploy that capital, how consistently we execute and ultimately, whether we can translate our technology and market opportunities into sustainable financial performance. A portion of the proceeds was used to repay our outstanding senior promissory notes and original issue discount notes, significantly strengthening our balance sheet. The remaining capital provides us with the working capital and financial flexibility to execute our growth priorities.

Importantly, having a stronger balance sheet does not change the need for financial discipline. We remain focused on careful capital allocation, disciplined spending and converting our commercial opportunities into revenue and improved profitability. Our priority now is execution and demonstrating measurable progress in our financial results. For shareholders who are newer to LiqTech, I would like to provide just a very brief high-level review of the strategy we have been implementing over the past several years.

Our objective is to build a more balanced, repeatable and profitable company around applications where our silicon carbide membrane technology provides a clear performance advantage and where customer adoption can scale. To begin with, commercial pool has become a much more important part of that strategy. We have invested in a standardized and modular QlariFlow platform, expanded our distribution network and built references across multiple geographies.

Next, Marine has also reengaged through our joint venture in China, which gives us local sales, sourcing, assembly, development and service capabilities in a market where local execution is essential. Our DPF and membrane business and our plastics business provide a steady base of activity and important manufacturing capabilities. The largest variable in our outlook remains Water for Energy and Water for Industry. These markets represent meaningful revenue opportunities for LiqTech, but sales cycles are typically longer and more complex.

Projects often require pilot testing, technical validation, customer approvals, capital budgeting and multiple layers of internal decision-making. As a result, project timing can be difficult to predict and is often influenced by customer processes that are outside our direct control. This means Water for Energy and Water for Industry can be significant drivers of our future growth, but it can also create variability in our quarterly and annual revenue. Our focus is, therefore, on building a broader pipeline, advancing multiple opportunities in parallel and converting more of these projects into firm orders.

Over time, we believe this should make the business less dependent on the timing of any single large project. Based on what we have learned from the market, we have refined our go-to-market approach for both Water for Energy and Water for Industry. In Water for Energy, going forward, we will focus on building strategic commercial partnerships that help us accelerate market penetration and convert our technology capabilities into commercial opportunities. In Water for Industry, we will take a more targeted approach, focusing our resources on selected applications where we see clear customer needs and a strong technology fit.

The steel industry is a good example, where our recent follow-on order demonstrates the potential to move from initial installation to broader multisystem deployments. Our objective is to build a more visible, repeatable and scalable opportunity pipeline while maintaining disciplined resource allocation. The second quarter illustrates both sides of our strategy. Commercial pool achieved record revenue and the Marine continues to execute against its order book.

Since quarter end, the U.S. industry wastewater reuse order and the $2.3 (sic) [ 2.1 ] million follow-on order from a U.S.-based steel manufacturer have further reinforced the progress we are making in selected Water for Industry applications. At the same time, delay in a larger Water for Energy project has reduced our revenue visibility for the remainder of 2026. As a result, we are revising our full year revenue guidance to a range of $20 million to $23 million. Importantly, even at the revised guidance range, we expect to deliver meaningful year-over-year revenue growth, reflecting the underlying process across our business. We are disappointed by this delay, particularly because we had expected this project to contribute revenue this year, but our response is not weak. We are putting greater emphasis and resources behind the markets where we see more repeatable demand, shorter sales cycles and a better revenue visibility.

At the same time, we will continue to pursue significant opportunities in Water of Energy, but in a more selective and increasingly partnership-driven manner. This is not a sudden change in direction. Rather, it's a continuation and acceleration of the strategy shift we have discussed it over the past several quarters, informed by what we have learned from the market. We now have a stronger balance sheet, growing commercial platform and significant market opportunities. But ultimately, we need to demonstrate that these strengths translate into improved financial performance. Our priorities are clear: execute on the opportunities in front of us, maintain financial discipline, improve profitability and build a more predictable and sustainable business. And let me be clear, achieving profitability as quickly as possible remains one of our highest priorities.

Let us talk about each area in more detail. Commercial Pool was the strongest area of business in the second quarter. Revenue reached a record $1.5 million compared with $0.8 million in both the second quarter of '25 and the first quarter of '26. The performance reflects the work we have done to standardize the QlariFlow platform, strengthen our distribution partnerships and establish a broader base of reference installations. During the quarter, we completed assembly of the systems for the Plumpton Aquatic and Leisure Centre project in Australia and our first U.S. commercial pool project in Worland, Wyoming.

The large pool system in Den Helder, Netherlands, which we announced in April is now operating successfully. These projects demonstrate that QlariFlow can serve different facility sizes, project designs and geographics. We are maintaining the advantage of a modular platform. We continue to have our focus in establishing new distribution relationships in the prioritized geographic regions. Expanding the partner network is an important part of the pool strategy because local partners are critical for identifying projects earlier, supporting system design and installation and providing the customer relationships needed to scale efficiently. Pools are attractive to LiqTech because the systems can be more standardized than our many large industry projects. The value proposition is straightforward and each successful installation can help create additional opportunities in the surrounding market and add aftermarket service business.

Transitioning to Marine. Marine revenue totaled $0.7 million in the second quarter compared with $0.4 million in the second quarter of '25 and $0.8 million in the first quarter of '26. During the quarter, we received factory acceptance test approval for the first 2 iCER dual-fuel water treatment units. This represents an important execution milestone and reflects the significant progress made by our team and our joint venture in China. We expect to deliver 1 additional iCER dual-fuel water treatment unit and 2 marine scrubber water treatment systems in the third quarter. We also secured a commercial order of 4 water treatment systems for EGR-equipped vessels in China with the first system currently expected to be delivered in December.

The China joint venture has allowed us to reestablish a stronger position in Marine by combining LiqTech's membrane technology with localized engineering, sourcing, assembly and service. We continue to manufacture our co-silicon carbon membranes in Denmark. We're using the joint venture to improve competitiveness and responsiveness in the Chinese shipbuilding market. The growing mix of iCER, EGR scrubber systems and related aftermarket opportunities gives us confidence that Marine can become a more consistent contributor over time.

Turning to Water for Energy. The most significant change occurred recently. A major customer went through an organizational change that affected the decision-making process for an important Water for Energy project that we had expected to contribute revenue in 2026. New decision-makers became involved and significant part of the customers' internal evaluation and approval process effectively had to restart. As the impact of this delay become clear, we reassessed what we could realistically deliver and recognized as revenue during the remainder of 2026.

Given the slower customer decision-making process, combined with the lead time required for certain critical equipment, we concluded that it was no longer prudent to maintain our previous full year revenue guidance. I want to be clear that we are disappointed by this delay. Our team has invested significant time and resources in technical validation, field engagement and commercial development. Importantly, we have not seen any change in the underlying need for our technology and the technical results remain compelling. The project has not been terminated and remains an active opportunity. Our relationship with the customer remains intact, and we continue to engage closely with the new decision makers as they work through their internal evaluation and approval process.

Within Water for Industry, the near-term opportunity set is becoming increasingly tangible, particularly in steel and other industry wastewater applications. Yesterday, we announced a $2.1 million follow-on order from a U.S.-based steel manufacturer for 4 additional industry wastewater filtration systems with approximately 75% of the order currently expected to be delivered by the end of 2026. This order builds directly on the successful deployment of customers' initial system, which uses our silicon carbide membrane technology to treat challenging wastewater with high oil content and significant variability as part of the customers' broader water reclamation process.

What is particularly important to us is the progressing of this customer relationship. We started with one system, allowing the customer to validate our technology under real operating conditions. Based on successful performance of that system, the customer has now moved forward with 4 additional systems. This demonstrates the potential of our strategy proven the technology in a demanding application, established strong customer reference and then scale from initial installation to a broader deployment. This transition from initial installation to a larger multisystem deployment is exactly the type of development we want to see in Water for Industry. It demonstrates the potential to convert successful technology validation into repeat business and larger commercial opportunities.

This week, we also announced an order from a new U.S. customer for a QureFlow QF-6 ceramic membrane filtration system to be installed at its new facility in Freeport, Texas. The system will treat wastewater generated from industry equipment cleaning operation and recycle the treated water back into the facility's wash water supply. This is an important proof point for several reasons. It brings a new U.S. customer to LiqTech, demonstrates the applicability of our standardized QureFlow platform beyond traditional produced water treatment and addresses a challenging and highly variable wastewater stream where consistent remove of suspended solids and oil is critical.

Most importantly, it delivers a clear economic and environmental benefit to the customer by reducing both wastewater disposal volumes and freshwater consumption. Together with the new steel industry order, this industry wastewater order reinforces our belief that selected water for industry applications can develop into a more repeatable and scalable business. Our standardized system provide customers with clear economic and sustainability benefits. We are allowing us to deploy proven solutions across similar applications. This is why we are allocating greater resource towards selected industry segments where we see strong technology fit, increasing customer engagement and a better near-term revenue visibility.

Finally, our DPF and membrane business remain important foundational part of LiqTech. DPF and membrane revenue was approximately $1 million in the second quarter compared with $1.3 million in both the previous year quarter and the first quarter of '26. The decrease primarily reflected temporary production delays caused by constrained availability of critical raw material. Plastics revenue was $0.9 million compared to $1.2 million in the second quarter of '25 and approximately $1 million in the first quarter of '26. Customer purchasing decisions slowed during the quarter and availability of raw material prices and the broader market uncertainty where both DPF and plastics experienced some pressure during the quarter, they continue to provide an important base of recurring customer activity and continue to the balance of our overall business portfolio.

To summarize, the second quarter delivered record commercial pool revenue, continued execution in Marine and meaningful progress in industry wastewater. These achievements were offset by the delay in Water for Energy that has reduced our near-term revenue visibility and lead us to revise our 2026 revenue outlook. While we are disappointed by timing change, we remain optimistic about the direction of the business. We have a stronger balance sheet, a broader shareholder base, growing traction in markets where we can build standardized and repeatable solution and a greater clarity around where to allocate our resources. Our priority now is execution, converting these advantages into more predictable revenue growth, improved margins and ultimately, sustainable profitability. Let me now turn the call over to David to review the financial results in more detail. I will then make a few closing comments before we open the call for your questions. David?

David Kowalczyk

Yes. Thank you, Fei, and good day, everyone. I will walk through our second quarter financial results, the revised full year outlook and the impact on the June financing on our balance sheet. The revenue for the second quarter of 2026 was $4.4 million compared with $5 million in the second quarter of '25, representing a decrease of 12%. The quarter included strong year-over-year growth in Commercial Pools and Marine, offset by lower Water for Energy activity, temporary production constraints in DPF and membranes and softer customer purchasing in plastics.

Within Commercial Pool, revenue was a record $1.5 million compared with $0.8 million in the prior year quarter. Marine revenue was $0.7 million compared with $0.4 million last year. These increases demonstrate the progress in the strategic growth markets Fei just discussed. DPF and membrane revenue was approximately $1 million compared with $1.3 million in the second quarter of '25. Plastic revenue was approximately $0.9 million compared with $1.2 million in the prior year quarter. As Fei noted, the DPF and membrane comparison was affected by raw material availability, while plastics reflected slower customer purchasing decisions in a volatile raw material environment. Gross profit for the second quarter was $0.4 million, representing a gross margin of 8.4%. This compares with a gross profit of $0.5 million and a gross margin of 9.8% in the second quarter of '25.

The year-over-year decline primarily reflected product mix, including a lower contribution from higher-value system activity as well as a lower utilization of manufacturing capacity, while we continue to manage costs carefully. These factors were particularly offset by procurement benefits and lower depreciation expenses. As we have discussed in prior calls, our current revenue level remains below the point where fixed production costs are fully absorbed. Improving gross margins level depends on both revenue scale and mix. Standardized Commercial Pool, Marine and selected industrial systems are important to that effort because they provide opportunities to reuse engineering, improve procurement, simplify manufacturing and create better operating leverage as volume increases.

Total operating expenses for the second quarter were $2.7 million compared with $2.6 million in the second quarter of '25, an increase of 4%. Approximately 60% of the increase was related to foreign exchange rate movements, given that a significant portion of our cost base is denominated in Danish crowns and euros. Selling expenses were $0.8 million compared with $0.8 million in the prior year quarter. Excluding currency effects, the increase primarily reflected the annualized impact of hires within the Chinese joint venture, continued investments in sales coverage in the U.S. and Europe and annualized cost for the U.S. service center.

General and administrative expenses were $1.6 million compared with $1.5 million in the second quarter of '25. Adjusting for currency movements, G&A remained stable and below general inflation as the cost of filling open positions were offset by savings in other overhead areas. Research and development expenses were $0.3 million compared with $0.2 million in the prior year quarter. The increase primarily related to membrane development and development work for Marine and Commercial Pool systems.

We continue to manage operating expenses with discipline while directing investments towards the areas that support commercial growth and more repeatable system platforms. Other expenses for the second quarter were $0.7 million compared with approximately $0.1 million in the comparable period of '25. The increase was primarily attributable to amortization of debt discount accrued and paid interest on the senior promissory notes and losses on foreign currency translation.

Net loss for the second quarter of '26 was $3.1 million compared with a net loss of $2.2 million in the second quarter of '25. Adjusted EBITDA was a negative $1.6 million compared with a negative $1.3 million in the prior year quarter, slight decline was due to the lower revenue and gross profit and currency-driven increase on operating expenses. Turning to our outlook. We are revising our expectations for the full year of 2026, adjust to a range of $20 million to $23 million. The revision primarily reflects the movement of Water for Energy projects that were previously expected to contribute in '26, but are now anticipated to be completed beyond the current fiscal year.

The range continues to contemplate strong performance from Commercial Pool and Marine, selected Water for Industry opportunities, including the new U.S. steel manufacturing follow-on order and ongoing contributions from DPF membranes and plastics. Approximately 75% of the $2.1 million order is expected to be delivered by the end of '26. The principal variable remains the timing of larger system orders. We have reduced the amount of Water for Energy revenue assumed in the outlook, but we have not removed this opportunity from our commercial pipeline. The revised revenue cadence will affect the timing of operating leverage.

Our priorities remain gross margin improvement, disciplined operating spending and careful working capital management. We will continue to align investment with the markets where we see the strongest visibility and the best opportunity to create repeatable, profitable growth. Turning to the balance sheet. We ended the second quarter with cash on hand, including restricted cash of $15.7 million as of June 30. This compares with $2.7 million at the end of the first quarter. The change primarily reflects the June public offering. The offering closed on June 8 and generated approximately $18 million in net proceeds. In connection with the transaction, we eliminated the remaining senior promissory notes and original issued discount notes.

As a result, LiqTech ended the quarter with a substantially stronger liquidity position and greater financial flexibility. We intend to use that flexibility carefully. The capital is not a substitute for operating execution. It gives us the ability to support working capital, pursue business development in target markets and make focused investments that can help accelerate growth. We will evaluate those investments against clear commercial milestones and continue to manage cash with discipline. And with that, let me now turn the call back to Fei.

Fei Chen

Thank you, David. Before we open the call for questions, I want to return to the message I shared at the beginning. LiqTech is building around a differentiated silicon carbon filtration platform that can solve difficult water and emission challenges across multiple markets. The opportunity is significant, and our responsibility is to translate the opportunity into a business that is more predictable, scalable and profitable. The second quarter demonstrates clear progress in Commercial Pool and Marine.

Since quarter end, the new U.S. industry wastewater treatment order and $2.1 million follow-on order from a U.S.-based steel manufacturer have provided further commercial validation of our technology and strengthen our confidence in the opportunity within selected industrial wastewater applications. At the same time, the quarter reinforced the need to remain disciplined in Water for Energy where customer-controlled project timing can create meaningful revenue volatility. We are responding by allocating greater resource towards markets where we have better visibility and a clear path to scale. We are pursuing water for energy opportunities more selectively and increasingly through strategic partnerships.

Across the business, we are focused on building repeatable system platforms, expanding our market reach through partnerships and remaining disciplined use of financial flexibility created by the June offering. We appreciate the support of both our long-standing and the new shareholders. We recognize the responsibility that comes with that support, and we are committed to earning it through disciplined execution, more predictable growth and improved financial performance. With that, Robert, we would be happy to take any questions.

Robert Blum

Great. Thank you very much, Fei and David, for the prepared remarks. [Operator Instructions] First here, would you speak to where process improvements driving profitability may be realized in the near term. Examples may be sales, assembly, water system engineering or another area for LiqTech.

Fei Chen

Very good question. We actually have been working intensively in the past 1 and 2 years really to make the cost reduction for our processes in order to speed up the profitability. I can mention, first of all, we are doing the standardized product across all the applications, as we mentioned, the marine area, the commercial pool area and also the water for industry area, we are now having our product standardized and that reduce the cost and also provide the scales of economy when the sales goes up.

And we're also working much more close to our procurement process purchasing for the raw materials and the components, we really improve on that, and that will provide us the cost reduction. And we're also using our joint venture in China to see if there's any other component and materials in China can be much more cheaper and attractive for us than we're normally purchasing in Europe. So those are very much things we're doing. We're also working very much on the inventory optimization. We're also working on the production efficiency and the quality control, all this contributing to the improvement of our costs.

And from the sales perspective, we're also working very much on using our sales pipeline and CRM system really to control where we're going to use the sales resource and where we're really going to invest in the technology and also the whole process to get the commercial results and because that also brings a lot of cost to us. So we also -- so overall from the beginning to the end, we are looking at each of steps to really make the cost reduction. We're still a long way to go because they continuously have the possibility to improve, but we are very much aware to do that.

Robert Blum

All right. Very good. Thank you. Next question here. Could you talk about the competitive advantages that the QureFlow system has versus the other systems on the market? And how long did the steel customer have your unit operational before they chose to add 4 more units?

Fei Chen

Our crossflow system is based on our silicon carbon membrane. And this is very unique because our membrane has the patented coating, makes it very suitable for the waters with very, very dirty content, high oil content and high suspended particles and also different impurity in the water. And that's actually exactly the reason why our system is really function well in the steel manufacturing industry. On top of our membrane, our system, because we call crossflow, is really a continued operation system, and we're able to have the water recycled continuously in the system, and that makes the system continuously safe cleaning and really reduce the risk for being blocking by the impurity in the water.

And the company used our system for the steel manufacturing waters, have been running our system for 10 months. And it has been very stable, and they were so amazed because before they're using polymer membranes and those membranes very easily got blocked and they have to be changed very often. That really brings a lot of OpEx for them, the costing. And also very often, they have to stop the treatment and replace and that really also caused the break in their production process. So our system can run continuously and for all the 10-month period and without any troubles, and we are very stable and keep the promise we have given to them. And that's actually the basis why they have decided to extend another 4 systems because they're really happy for the performance of our system.

Robert Blum

Okay. Very good. The next question here is, are you seeing a larger number of pool system sales? Or are you seeing larger sales per system, sort of the size of the system versus the quantity of the systems?

Fei Chen

We see both. I mean we -- right now, majority of our sales still is in Europe, especially in North Europe. And -- but we're now coming to U.S. with a strong partner. And also, as you hear, we actually already finished the first pool system. It's going to be installed in U.S. in the quarter 3 -- by the end of quarter 3. So if we continue coming to the U.S., we will continue to come to U.S. In U.S., the systems are bigger. they are much bigger than Europe.

And as you also hear, we actually got a very big system in Australia and also in Holland. So we're working on both the bigger system and also the volume. But of course, we would rather go to the bigger system because you got the revenue faster and much more efficient sales, and we're seeing both.

Okay. Very good. Next question here is how many iCER water treatment units do you forecast could be sold in an average year? And how many annual units do you have capacity for?

Fei Chen

That's a very good question. I mean the market is quite big, not only iCER, it's iCER combined with EGR because iCER is about 30% of market and EGR is 70% of market. So these 2 technology, they kind of parallel and share the market. And we are very happy. We already got EGR sales order, and we're going to deliver by end of this year. So we are also going to the EGR market. So right now, according to the Internet data, there's 600 boats and vessels to be delivered from now to 2028, '29 and the combination of iCER and EGR. So our goal definitely -- we would like to get a substantial amount of those vessels and really to get our installations.

So we are working in China to the assembly part. And what we're doing is we find some very good partners in China do the assembly for us. So in this way, our assembly capacity to be quite flexible. So we're able to increase quite fast in this way. So we don't see that as really a challenge. So what we now really focus on is to finalize the standardize of our system for the marine application, both for iCER, EGR and also for scrubber. So in this way, we're really able to speed up very fast when the sales coming. And we see a very good cadence, both for the sales and also delivery in this area.

Robert Blum

Very good. I am showing no further questions here. So with that, Fei, I will turn it back over to you for any closing remarks.

Fei Chen
