Valuation assumptions are editorial choices, not measured; beta is not measured.

Valuation methods

  • DCF (discounted cash flow)unavailable · the reported interest expense is far older than the latest period (the filer changed its XBRL tag): a stale figure is not used
  • Peers: EV/EBITDAunavailable · net debt missing: EV cannot be bridged to equity (missing debt is not zero)
  • Peers: P/Eunavailable · the base of the ratio is not positive

    In brief

    LiqTech International makes silicon carbide ceramic filters and membranes, liquid filtration systems and plastic components, with operations in Denmark, the US and China. The company has not yet reached profitability, and sales fell in the second quarter of 2026, so the trajectory of capital and costs remains in focus. Revenue for fiscal 2025 was 16.5 million USD, with a net loss of 8.6 million USD 1.

    SWOT

    Strengths

    • Patented silicon carbide membrane technology offers superior chemical resistance and durability 1.
    • The company integrates membrane, system and plastic component manufacturing vertically 1.
    • The installed base of marine scrubber systems provides a starting point for new demand from dual-fuel engines 1.

    Weaknesses

    • The company has not yet reached profitability and reports recurring net losses 1.
    • Manufacturing capacity is underutilised, which weighs on gross margins 1.
    • Revenue depends on a small number of large customers, and orders can be delayed or cancelled 1.

    Opportunities

    • The market for produced water from oil and gas operations could grow considerably 1.
    • Dual-fuel engines could open a new water treatment market for vessels built in Asia 1.
    • Expansion into the US commercial pool market through distribution partnerships could diversify sales 1.

    Threats

    • Trade tariffs and retaliatory measures could raise costs and restrict market access 1.
    • Competition from large industrial companies could limit market share gains 1.
    • If scrubber regulations change, demand for water treatment units could decline 1.

    Risks

    • Capital needs and going concernhigh

      The company may need additional funding, and a shortfall of capital could affect the going concern assumption 1.

    • Customer concentrationhigh

      A small number of customers account for a large share of sales, and losing one could significantly affect results 1.

    • Tariffs and international trademedium

      Tariffs and trade restrictions could raise costs and disrupt the supply chain 1.

    • Energy costsmedium

      Volatile energy prices in Europe could affect profitability, particularly for production in Denmark 1.

    • Raw material supplymedium

      A shortage of silicon carbide or rising prices could delay deliveries and reduce margins 1.

    Investment thesis

    What would need to be true (bull case)

    • If demand for water treatment from dual-fuel engines materialises, the company could draw on its installed base of marine scrubbers 1.
    • Lower net losses and operating costs could lead to a clearer path to profitability if sales grow 1.
    • Patented SiC technology and vertical integration could offer an edge over conventional ceramic or polymeric filters 1.

    What would break the thesis

    • The company could keep posting losses if revenue does not recover from the decline seen in the second quarter of 2026 2.
    • Dependence on a few large customers makes revenue hard to forecast, and delayed orders could affect results 1.
    • The need for additional funding could lead to dilution for shareholders or restrictive borrowing terms 1.

    Products, market & competition

    AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

    The business

    LiqTech International, Inc. is a clean technology company, operating from Denmark, that manufactures silicon carbide (SiC) filters and membranes for purifying gases and liquids 1. Its activity is split into three areas: ceramic membranes and liquid filtration systems, diesel particulate filters (DPF) for emissions control, and plastic components 1. Products ship directly from the Danish plants, and marine water treatment systems are assembled in China 2.

    The company was incorporated as Blue Moose Media, Inc. in Nevada and changed its name to LiqTech International in October 2011 1. Revenue for fiscal 2025 grew year on year, mainly from deliveries of pool and industrial systems and plastic components, partly offset by lower DPF filter sales 1. The net loss narrowed, but the company continued to operate under a going concern assumption that depends on additional funding 1.

    In the near term, activity depends on the timing of system orders, which can be uneven from quarter to quarter. In the second quarter of 2026 revenue fell, mainly because a large 2025 energy system delivery did not recur, while sales of pool and marine systems rose 2. The company also reported a lower gross margin, showing how sensitive profitability is to product mix 2.

    Segments

    Liquid filtration systems

    This is the main line focused on SiC membranes, with applications in pool water, produced water from oil and gas, industrial wastewater and marine scrubber water treatment 1. The company estimates a 14% share of the marine scrubber water treatment unit market, where it has sold more than 170 units since 2018 1.

    Diesel particulate filters (DPF)

    SiC DPFs are sold into retrofit and OEM markets for vehicles, generators and non-road equipment 1. Filter sales declined in 2025 as the company refocused on sub-segments outside automotive where it sees higher future demand 1.

    Plastic components

    This plastics fabrication business serves the food and beverage, pharmaceutical and clean technology industries and supports vertical integration of filtration system components 1. Component sales declined in the second quarter of 2026 2.

    Market context

    The company frames its addressable market at several levels: the global industry and municipal wastewater equipment market is about 300 billion USD, filtration technology is a 14 billion USD market, and LiqTech's addressable market is about 6 billion USD 1. According to the same source, the total industrial water and wastewater treatment market could reach 7.7 billion USD by 2030 1. Demand for high-quality water in industrial processes and sulfur emission rules for ships are the main drivers cited by the company 1.

    The produced water market from oil and gas operations could grow significantly, and the company has validated commercial installations in the Middle East and the US 1. However, exposure to industrial investment cycles and orders from a small number of customers makes results volatile from year to year 1.

    Trends

    • Maritime sulfur emission rulestailwind

      The IMO SOx rules led to the installation of scrubbers, and hybrid or closed-loop systems require water treatment, which could create demand for the company's products 1. The market could change, however, if the rules shift or scrubber adoption slows 1.

    • Shift to dual-fuel enginestailwind

      Most newly ordered vessels are built with dual-fuel engines, which could open a new market for exhaust gas recirculation water treatment 1. The company set up a joint venture in Nantong, China, to speed entry into this market 1.

    • Energy and raw material costsmixed

      The company depends on gas and electricity prices for high-temperature kilns, and energy volatility or shortages of inputs such as silicon carbide could affect margins 1. Underutilised manufacturing capacity has also been identified as a pressure on profitability 1.

    Competitive position

    LiqTech's products compete with filtration technologies made from ceramic, aluminium oxide and polymeric materials, and most competitors are large industrial companies 1. The company differentiates itself by combining patented SiC membranes with integrated modular systems and application expertise 1.

    The company's stated advantage is the chemical resistance and durability of silicon carbide compared with aluminium oxide filters, but this advantage depends on how well new applications are validated with customers 1. The supplied sources do not name listed direct competitors.

    • Ceramic and aluminium oxide filter makers

      Competitors referred to generically in the annual report, without precise names in the supplied sources.

    • Polymeric membrane technology providers
