Overview

LiqTech International, Inc. is a clean technology company that provides state-of-the-art gas and liquid purification products by manufacturing ceramic silicon carbide filters. For more than two decades, we have developed and manufactured products of re-crystallized silicon carbide. We specialize in two business areas: ceramic membranes for liquid filtration and diesel particulate filters (DPFs) to control soot exhaust particles from diesel engines. Using nanotechnology, we develop proprietary products using patented silicon carbide technology. Our products are based on unique silicon carbide membranes that facilitate new applications and improve existing technologies. We market our products from our offices in Denmark and local representatives and distributors across Europe, Middle East and Asia, with the products shipped directly to customers from our production facilities in Denmark.

The terms “LiqTech”, “we”, “our”, “us”, the “Company” or any derivative thereof, as used herein, refer to LiqTech International, Inc., a Nevada corporation, together with its direct and indirect wholly-owned subsidiaries, including LiqTech USA, Inc., a Delaware corporation (“LiqTech USA”), which owns all of the outstanding equity interest in LiqTech Holding A/S, a Danish limited company, organized under the Danish Act on Limited Companies of the Kingdom of Denmark (“LiqTech Holding”), together with its direct wholly-owned subsidiaries LiqTech Ceramics A/S (“LiqTech Ceramics”), LiqTech Water A/S (“LiqTech Water”), LiqTech Water Projects A/S (“LiqTech Water Projects”) and LiqTech Plastics A/S (“LiqTech Plastics”), all Danish limited companies organized under the Danish Act on Limited Companies of the Kingdom of Denmark, and LiqTech NA, Inc., a Delaware corporation (“LiqTech NA”). Collectively, LiqTech USA, LiqTech Holding, LiqTech Ceramics, LiqTech Water, LiqTech Plastics, and LiqTech NA are referred to herein as our “Subsidiaries”.

We conduct and manage our operations from our office and manufacturing facilities in the Kingdom of Denmark, more specifically Hobro, Aarhus, and Ballerup in the Copenhagen area. We are currently working to establish manufacturing operations in China.

Our Products

We manufacture and sell a broad range of ceramic membranes and systems for the filtration of liquids and diesel particulate filters to control soot exhaust particles from diesel engines. We also provide plastic parts through the recently acquired BS Plastic A/S for various internal and external industrial applications. 

Silicon Carbide Ceramic Membranes for Liquid Filtration

For more than two decades, LiqTech has developed, manufactured, and sold innovative silicon carbide ceramic filtration technologies for liquid and gas purification. Our product portfolio consists of silicon carbide ceramic filters for liquid purification and diesel particulate filters for gas purification. Based on our continuous R&D, patented technologies, and evolved production methods, we are able to produce state-of-the-art silicon carbide filters.

Our products are manufactured with a silicon carbide ceramic membrane based on patented technology. We are not aware of other companies that make both the substrate (honeycomb) and the membrane (the part that accomplishes the filtering) solely from silicon carbide. Our products are based on the following silicon carbide membrane technologies:

Diesel Particulate Filters (DPFs) for Gas Purification

We offer diesel particulate filters for exhaust emission control solutions to the verified retrofit and original equipment manufacturer (OEM) market through our direct sales force. DPF sales are generally made to distributors specializing in sales to end-users. We use a proprietary “nano wash coat” to provide a catalytic coating for anything from diesel particulate filters to catalytic converters. Our DPF products are sold worldwide under the LiqTech brand.

We have developed a robust silicon carbide diesel particulate filter that is especially effective for vehicles that produce a high soot load. If properly maintained, a LiqTech DPF can last as long as the vehicle’s engine. Our DPFs are ideal for off-road vehicles because of their strength, chemical non-reactive nature, temperature resilience, and thermal conductivity.

Our DPF filters can handle higher soot loads than filters that do not use a silicon carbide membrane, making them ideal for situations in which engines infrequently reach high enough temperatures to burn off the soot. Examples include: 

Future tightening legislation in the marine industry has also created a new opportunity for our DPF product to reduce black carbon emissions from shipping.

Turnkey Water Treatment Solutions

LiqTech develop, manufacture, and sell liquid filtration systems using our patented silicon carbide technology (sometimes also referred to herein as our “SiC Filters”). Our current focus is on marine scrubber wastewater, hydrocarbon production-derived contaminated water, which we refer to herein as “produced water”, removal of heavy metals in mining and energy applications, pre-filtration for reverse osmosis in drinking water, and other industrial applications.

Our SiC ceramic membrane systems have been used in the following applications by our clients:

Besides the applications mentioned above utilizing silicon carbide ceramic membranes, LiqTech has many other industrial water treatment applications that do not use ceramic membranes. These applications include:

Highly Flexible & Innovative Plastic Manufacturing

LiqTech provides highly flexible and innovative plastics manufacturing, focusing on machining, welding, bending, and solvent cementing. With an intense focus on customer demands, LiqTech serves market leaders in the cleantech, pharma, food, healthcare, and graphics industries.

Our Competitive Strengths

Our products compete with other filters that are made of ceramic and polymeric materials. Most of our competitors are large industrial companies; however, we believe our patented technology allows us to produce high-quality products that provide an advantage over many of our direct and, in many cases, larger competitors. We intend to continue investing in R&D with the aim of developing new technologies and improving our existing products to reinforce our competitive advantages, retain our existing customers, and acquire new customers.

We believe the following strengths underpin our ability to increase revenue and profitability:

Our Strategy 

Our strategy is to create stockholder value by leveraging our competitive strengths in silicon carbide filters, membranes, and water treatment solutions through focus on discrete applications in key end markets. Essential features of our strategy include:

Our Industry 

Overview

We serve primarily two industries: the liquid filtration market and the diesel particle filter (DPF) market. Our goal is to leverage our products and technologies into industrial liquid filtration applications that offer significant growth opportunities and take advantage of favorable market trends.

Liquid Filtration Market

The market for marine water filtration systems is rapidly developing due to new regulations for sulfur and ballast water emissions. Industry experts estimate that 8,000-10,000 ships will be retrofitted with a scrubber water treatment system over the next five years. At the end of 2019, the industry statistics note that nearly 4,000 ships have installed or ordered scrubbers (according to the DNV GL report March 2020), with most installations being open-loop scrubbers. Open-loop scrubbers discharge the wash water directly into the sea. The addressable market for LiqTech is focused on closed-loop scrubbers, where the scrubber wash water is routed through the LiqTech filtration system to remove sulfur and other particulates, and the clean water is then recycled as wash water.

As noted above, the use of open-loop scrubbers to clean the exhaust from marine engines that use high-sulfur residual oil and diesel fuels may lead to the discharge of high concentrations of harmful compounds in the waters from vessels using such scrubbers. Several trials have been conducted on board vessels by scrubber suppliers to define the constituent concentrations in wash water discharge. The research concluded that scrubber wash water also contains suspended solids, heavy metals, hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). Before the scrubber wash water is discharged, it must be treated to remove solids. LiqTech’s water treatment systems can be used to remove the solids from the wet scrubber wash water. The treatment process includes a pre-filtration step followed by a LiqTech SiC membrane filtration. Treated water quality is monitored (NTU, PAH, and pH) before discharge. We believe that many of the open-loop scrubbers already installed will eventually be converted to closed-loop (where the LiqTech filtration system is employed), thus resulting in a significantly larger market for LiqTech. The Company is globally engaging with scrubber equipment suppliers, ship owners/operators, and shipyards. Furthermore, we present our water treatment and filtration solutions at marine conferences and trade shows, while also through digital marketing.

In addition to our marine scrubbers, LiqTech offers packaged filtration systems consisting of ceramic SiC and conventional reverse-osmosis (RO) membranes for industrial and municipal customers. We anticipate that global demand will increase for robust and low operating expense products such as ours that are well-suited for mobile and modular systems. RO membranes are increasingly used to produce drinking water (desalination of seawater or brackish water), demineralized water for industrial processes (boiler feed water, microelectronics production), and food processing and pharmaceuticals. Moreover, many laboratories rely on pure water, for which demineralization is an essential step. LiqTech is differentiated by what we believe is our superior SiC membrane technology and by being able to provide a complete water treatment system. According to Global Industry Analyst report, dated April 2021, the global membrane filtration market is expected to grow at a compound annual growth rate (CAGR) of 5.3%, from $14 billion in 2020 to $20 billion in 2027.

Generally, we also see a growing, global demand for higher-quality re-injection water from unconventional oil and gas productions. In addition, we see tightening water discharge legislation, increasing water usage (more water produced per barrel of oil), and the introduction of Enhanced Oil Recovery (“EOR”) techniques. The tightening water discharge legislation is a problem for conventional treatment and filtration technologies; however, our SiC Filters can mitigate these challenges, and we believe the increasing demand represents a favorable market trend for our business.

Water is essential to life on earth, and clean water shortages are affecting billions of people. Today, 2.2 billion people lack safely managed drinking water, and 3 billion people worldwide lack basic handwashing facilities at home. In addition, more than 700 million people could be displaced due to water scarcity (according to the UN). According to the World Health Organization, approximately 361,000 children die every year due to unsafe water and lack of basic sanitation. Due to the growing need for pure water for drinking and industrial purposes, the market for water filtration is growing rapidly, with more and larger plants being commissioned all over the world.

Diesel Particulate Filter (DPF) Market

Our legacy business related to the provision of DPF filters is expected to continue growing across Asia, Europe, and the United States as regulators require diesel engines to comply with new and more stringent environmental rules and regulation. In Europe, for example, German cities continue enforcing increased requirements for diesel engines to include DPF filters, with the same trend also taking place in select Asian countries.

Furthermore, our proprietary DPF technology has paved the way for new market opportunities such as black carbon marine, where our solutions allow both ocean-going and inland marine vessels to comply with current and future regulatory thresholds as defined by both IMO and regional regulators. In Asia, we are currently intensifying our commercial efforts and expanding our regional manufacturing capabilities in China with the aim of capitalizing on its future market potential.

According to an industry publication (Diesel Particulate Filter – Global Market Outlook (2017-2026)), dated January 16 2019, the global market for new DPF filters manufactured by OEMs is expected to increase approximately 13% per year from 2017 to 2026. Diesel emissions consist of several toxic gases and particles: particulate matter (soot), carbon monoxide, and hydrocarbons. Soot has been linked to a variety of human health problems. Reducing diesel emissions will have both health and social benefits, along with reduced costs.

In response to these health impacts, governments have been implementing legislation to regulate emissions from diesel engines. California implemented the Diesel Risk Reduction Plan, and New York City implemented binding directives for the retrofitting of buses, garbage trucks, and construction machines. In the European Union, Directive EC 715/2007 of June 20, 2007, defines particle count limits for certain cars and light utility vehicles. Also, low emission zones have been implemented locally in various places in Europe, creating a patchwork of regulation.

The Asian markets have shown an improved standard of living due to financial growth, which has led to increased sales of vehicles in the region. At the same time, pollution in major cities has reached high particulate matter levels. As a result, the Chinese government has introduced additional regulations, including new emissions standards, faster than previously anticipated. We also believe the high pollution levels will increase the need to retrofit existing vehicles.

Research and Development

We have eighteen (18) full-time employees that are primarily engaged in research and development activities pertaining to the developing of technology and intellectual property rights related to silicon carbide product forms, applications, and manufacturing processes.

Manufacturing

We currently manufacture our DPF and membrane products in Ballerup, Denmark. We assemble our water treatment systems in Hobro, Denmark, and we manufacture plastic products in our facilities located in Aarhus, Denmark. We plan to expand our production capacity in China and the Middle East, primarily through investment in additional facilities and manufacturing equipment for both membranes and filter products.

Raw Materials

The main raw materials we use in our manufacturing processes are silicon carbide, steel, plastic, platinum, and palladium. We purchase these commodities from various sources generally based upon availability and price.

Sales, Marketing and Distribution 

Our products are sold primarily to large industrial customers for gas and liquid filtration. The Company sells through direct sales, systems integrators, distributors, agents, and partners.

The Company initially focused on selling its DPF filters to the automotive industry. In 2014, we acquired Provital Solutions, a Danish filtration system manufacturing company, which enabled us to shift our focus to providing complete, modular liquid filtration systems. The Company’s liquid filtration systems business is now rapidly expanding, focusing on the marine industry and other industrial applications in mining, power generation, aquaculture, oil and gas, and other applications within the pool industry, water reclamation, and drinking water.

We plan to actively market our existing products to new customers as we increase our production capacity. As of March 2022, we employed eleven (11) full-time salespeople in addition to distribution agents. We promote our products through direct sales to potential customers and marketing activities such as participation in tradeshows and exhibitions, with a heavy focus on digital marketing.

In certain instances, our products are delivered to the end customer through system integrators. These system integrators use our filtration products in larger filtration systems, which eventually are installed in products used by the end customer. Due to legislative regulation, system integrators are often required by end customers to receive approval for their systems, including the components used in such systems, which requires significant time and expenses. As a result, we believe that certain system integrators that use our products will not replace our filters with competitive products unless there are compelling reasons to do so. 

Intellectual Property

We have one issued patent in the United States that we co-own with a third party, two issued patents in Denmark, three issued foreign patents (Germany, China, and South Korea) that we co-own with a third party, and one pending European patent application that we co-own with a third party. The United States patent that we co-own is generally effective for 20 years from the filing date (July 8, 2004) of the earliest U.S. or international application to which it claims priority. The scope and duration of each of our foreign patents vary in keeping with local laws. On July 7, 2014, we obtained a new Danish patent application related to our silicon carbide membrane technology.

We also rely on trade secret protection for our confidential and proprietary information. Trade secrets, however, can be difficult to protect. We may not be able to maintain our technology or know-how as trade secrets, and competitors may develop or acquire equally valuable or more valuable technology or know-how related to the manufacture of comparable silicon carbide products. We also seek to protect our confidential and proprietary information, in part, by requiring all employees, consultants, and business partners to execute confidentiality and/or nondisclosure agreements upon the commencement of any employment, consulting arrangement, or engagement with us. These agreements generally require that all confidential and proprietary information developed by the employee, consultant, or business partner, or made known to the employee, consultant, or business partner by us, during the course of the relationship with us and thereafter, be kept confidential and not disclosed to third parties.

We also believe that having distinctive names is an important factor in marketing our products and therefore use trademarks to brand some of our products. As of March 2022, we had one trademark registration in the United States (LiqTech NA) and four trademark registrations in the European Union (AQUA SOLUTION, CoMem, CDPX, and FUTURE FILTRATION).

Government Regulation

We do not believe that we are subject to any special governmental regulations affecting our products in the countries in which we operate. We are subject to numerous health and safety laws and regulations. In the United States, these laws and regulations include the Federal Occupation Safety and Health Act and comparable state legislation. We are also subject to similar requirements in other countries in which we have extensive operations, including Denmark. We actively seek to maintain a safe, healthy and environmentally friendly workplace for all of our employees and other stakeholders.

Environmental Matters

We are subject to a broad range of environmental laws and regulations that govern, among other things, air emissions, wastewater discharges, and the handling, storage, disposal, and release of waste and hazardous substances. It is our policy to comply with all applicable environmental requirements at each of our facilities. We are subject to similar requirements in Denmark and other European countries. From time to time, we have identified minor environmental compliance issues at our facilities. To date, compliance with environmental matters has not had a material effect upon the Company’s capital expenditures, results of operations, or competitive position.

We believe that, due to the constant focus on the environment, clean air, and clean water standards throughout the world, more stringent regulations in the U.S., Europe and elsewhere around the world are likely as governmental agencies seek to improve standards required for certification of products intended to promote clean air and water. In the event our products fail to meet these changing standards, some or all our products may become obsolete, which could have an adverse effect on our business, operating results, financial condition, and long-term prospects.

Competition 

Our products compete with other filters that are made using both ceramic and plastic membranes. Most of our competitors are large industrial companies; however, we believe our patented technology, manufacturing know-how, and trade secrets allow us to produce high-quality products that provide an advantage over many of our competitors, many of which have greater financial, technological, manufacturing and personnel resources. We intend to continue to devote resources to the development of new technologies and the improvement of our products to retain existing customers and acquire new customers.

Employees

At December 31, 2021 we had 120 employees, including 67 in production, 12 in administration, 18 in research and development, 21 in sales and engineering and 2 in executive management.

Certain employees in Denmark are represented by workers’ councils that have collective bargaining agreements. With the exception of such Danish employees, no other employees are members of a labor union or are represented by workers’ councils that have collective bargaining agreements. We believe that we have good relations with our employees.

RISKS RELATED TO OUR BUSINESS AND OPERATIONS 

The COVID-19 pandemic could have a material adverse effect on our business, results of operations and financial condition in the future.

Our business could be adversely affected by the effects of a widespread outbreak of contagious disease, including the outbreak of respiratory illness caused by the novel coronavirus first identified in Wuhan, Hubei Province, China (COVID-19). The COVID-19 pandemic has resulted in authorities worldwide implementing numerous measures to contain or mitigate the outbreak of the virus, such as travel bans and restrictions, border controls, limitations on business activity, social distancing requirements, quarantines, and shelter-in-place orders. These measures have caused, and are continuing to cause, business slowdowns or shutdowns in affected areas, both regionally and worldwide. The impact of the pandemic on our business and operations and our ability to execute our strategic plans remains uncertain and will depend on many unpredictable factors outside of our control, including, without limitation, the extent, trajectory and duration of the pandemic; the development, availability and distribution of vaccines and other effective treatments to treat the COVID-19 virus and any new variants thereof; the emergence of new variants that are more contagious, symptomatic or fatal and the time the medical community requires to respond to such variants; the imposition of and compliance with protective public safety measures; the impact of the pandemic on the global economy; and the related impacts on our development pipeline and demand for our products.

Since 2020 and throughout 2021, management has initiated several precautionary initiatives across our business in accordance with local regulations and guidelines to mitigate the spread of COVID-19. These precautions have impacted the way we carry out our business, including additional sanitation and cleaning procedures in our production and other facilities, temperature and symptom confirmations, remote working when possible, and implementation of social distancing and staggered worktime requirements for our employees who must work on-site. If we are required to continue such measures for an extended period, it could impact the ability of our employees to collaborate efficiently. In addition, the loss or unavailability of our production staff or other key employees and executives, as a result of sickness of employees or their families or the responsibility of employees to manage family obligations while working from home, could continue to negatively impact our business and operations including our ability to operate or execute our business strategy efficiently. Continued employee telecommuting activity also increases the risk of a security breach of our information technology systems. The changed environment under which we are operating could have an impact on our internal controls over financial reporting.

Moreover, the ongoing impacts of the COVID-19 pandemic could result in interruptions or delays in the operations of regulatory authorities, which may impact review or approval timelines; delays in necessary interactions with other agencies and contractors due to limitations in employee resources or forced furlough of government employees; termination of, or difficulties in procuring or maintaining, arrangements with third parties upon whom we depend such as manufacturers, including contract manufacturing organizations, suppliers and other strategic partners; and disruptions or restrictions on our ability to pursue partnerships and other business transactions.

As a result of the COVID-19 pandemic and the geopolitical unrest and general restrictions on the global supply chain amid increased global trade combined with challenges from the Evergreen blockage of the Suez Canal in 2021, our business continues to be exposed to significant disruptions and delays in the global supply chain.

Since the start of the COVID-19 pandemic in early 2020, there has been an overall decline in new orders, particularly in the shipping industry, due to reduced investment caused by demand disruption and the volatility of oil prices. The effects of a prolonged pandemic could result in a prolonged negative impact on investment in the shipping industry and in other industries. In addition, if COVID-19 impacts the financial position of our customers or any of our collaboration partners, we may have difficulty collecting receivables or milestone payments, and our business and results of operations could be exposed to risks associated with uncollectible accounts or defaults on contractual payment obligations by our collaboration partners. If we are unable to generate sufficient cash from operations due to the impacts of the COVID-19 pandemic or otherwise, we may need to raise additional funds. The duration and severity of any further economic or market impact of the pandemic remains uncertain as exemplified by the rapid increase in the COVID-19 pandemic in late 2021 due to Omicron variant, thus there can be no assurance that it will not have an adverse effect on our liquidity and capital resources, including our ability to access capital markets, in the future, on terms that are favorable to us, or at all.

Historically, we have been dependent on a few major customers for a significant portion of our Company's revenue. Our revenue could decline if we are unable to maintain or develop relationships with additional customers and our results of operations could be adversely affected if any one of these customers is unable to meet their financial obligations to us.

For the year ended December 31, 2021, our four largest customers accounted for approximately 12%, 10%, 9%, and 6% of our net sales (approximately 37% in total). For the year ended December 31, 2020, our four largest customers accounted for approximately 27%, 10%, 8% and 8% of our net sales (approximately 53% in total). If we are unable to diversify our customer base, our future results will be heavily dependent on these customers. Our dependence on a limited number of customers means that the loss of a major customer or any reduction in orders by a major customer would materially reduce our net sales and adversely affect our results of operations. We expect that sales to relatively few customers will continue to account for a significant percentage of our net sales for the foreseeable future; however, these customers or our other customers may not use our products at current levels in the future, if at all. We have no firm, long-term volume commitments from any of our major customers, and we generally enter into individual purchase orders with our customers, in certain cases under master agreements that govern the terms and conditions of the relationship. We have experienced delays or cancellations of orders and fluctuations in order levels from period to period and expect that we will continue to experience such delays, cancellations, and fluctuations in the future. Customer purchase orders may be delayed or cancelled, and order volume levels can be changed with limited or no penalties. We may not be able to replace cancelled, delayed, or reduced purchase orders with new orders. If any one of these customers reduces its demand for our products, it will likely have a material adverse effect on our operations.

Furthermore, a significant portion of our accounts receivable is concentrated with a few major customers, who may not be able to meet their financial obligations to us. The failure of any such customers to pay amounts owed to us in a timely fashion or at all could have an adverse effect on our results of operations. The Company is also exposed to credit risk on its accounts receivable, and this risk is heightened during periods when economic conditions worsen. The Company's outstanding receivables are not covered by collateral or credit insurance. The Company's exposure to credit and collectability risk on its receivables may also be higher in certain international markets, and its ability to mitigate such risks may be limited. While the Company has procedures to monitor and limit exposure to credit risk on its receivables, there can be no assurance such procedures will effectively limit our credit risk and avoid losses.

We will need to raise additional funds to develop our business, which may adversely affect our future growth.

We expect to finance our anticipated future growth and possibly future strategic acquisitions through public or private equity offerings or debt financings. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay, or reduce the scope of, our plans to grow our revenues, to consummate one or more strategic acquisitions, or to scale back our business plans. In addition, we could be forced to reduce or forgo attractive business opportunities. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. In addition, debt financing, if available, may involve restrictive covenants. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. Our access to the financial markets and the pricing and terms we receive in the financial markets could be adversely impacted by various factors, including changes in financial markets and interest rates.

Changes in China’s political, social, regulatory, or economic environments may affect our financial performance.

Our financial performance related to the new manufacturing facility in Taicang and the commercial potential in China may be affected by changes in the Chinese political, social, regulatory or economic environments. The role of the Chinese central and local governments in the Chinese economy is significant. Chinese policies toward hazardous materials, environmental controls, air pollution, economic liberalization, laws and policies affecting technology companies, foreign investment, currency exchange rates, taxation structure and other matters could change, resulting in greater restrictions on our ability to do business and operate our manufacturing facility in China. We have observed a growing fluidity and tightening of regulations concerning hazardous materials, other environmental controls and air pollution. The Chinese government could revoke, terminate or suspend our operating licenses for reasons related to environmental control over the use of hazardous materials, air pollution, labor complaints, national security and similar reasons without compensation to us. Further, the central government encourages employees to report possible safety or environmental violations to regulatory agencies, even when there may not be actual violations. Any failure on our part to comply with governmental regulations could result in the loss of our ability to manufacture our products, generate revenue, and cover fixed costs in China.

The Chinese central government is increasingly aware of air pollution and other forms of environmental pollution as evidenced in the new five-year plan.

The Chinese central government is demonstrating strong leadership to improve air quality and reduce environmental pollution as evidenced in the new 14^th five-year plan related to 2021-2025. These efforts may impact manufacturing companies through mandatory shutdowns, increased inspections, and regulatory reforms to ensure the Chinese manufacturing industry complies with the overall targets for climate, pollution, and R&D. Furthermore, the timing and impact on demand for environmental solutions required to help achieve the overall climate targets remain uncertain as local, regional and national legislation and government actions may be subject to delays. Consequently, the financial impact from the Taicang manufacturing facility could be negatively impacted by both manufacturing delays or reduced demand given the risk and timing uncertainties related to the new five-year plan including relevant emission legislation, which would frustrate our ability to generate revenue and cover fixed costs.

If China places restrictions on freight and transportation routes and on ports of entry and departure this could result in shipping delays or increased costs for shipping.

If the Chinese government were to place additional restrictions on the transportation of materials and products in and out of China, then our ability to transport our raw materials or products could be limited and result in manufacturing delays or bottlenecks at shipping ports, affecting our ability to deliver products to our customers. During periods of such restrictions, we may increase our stock of critical materials for use during the period that these restrictions are likely to last, which will increase our use of cash and increase our inventory level. Any of these restrictions could materially and adversely impact our results of operations, cash flow, and our financial condition.

Our international operations are exposed to potential adverse tax consequence in China.

Our international operations create a risk of potential adverse tax consequences. Taxes on income in our future China-based operations are dependent upon acceptance of our operational practices and intercompany transfer pricing by local tax authorities as being on an arm's length basis. Due to inconsistencies among taxing authorities in application of the arm's length standard, transfer pricing challenges by tax authorities could, if successful, materially increase our consolidated income tax expense. We will be subject to tax audits in China, and an audit could result in the assessment of additional income tax against us. This could have a material adverse effect on our operating results or cash flows in the period or periods for which that determination is made and could result in increases to our overall tax expense in subsequent periods.

Adverse conditions or events affecting the marine transportation industries may have a material adverse effect on our business.

Global health crises, such as a prolonged outbreak of COVID-19, can significantly impact us and our customers and suppliers. For example, the global shipping industries have been negatively impacted by the coronavirus outbreak due to increased travel restrictions and may be further adversely affected by an extended shutdown of various businesses in the impacted regions. In light of this operating environment, shipping companies that carry goods may begin to significantly reduce the number of seaborne vessels or reroute ships as measures to stop the spread of the coronavirus negatively impact the demand for seaborne transport of goods. This, in turn, can adversely affect the demand for our marine scrubbers to these shipping customers if many vessels sit idle or are taken out of service during the outbreak.

Furthermore, the volatility in oil prices caused by demand destruction from economic shutdowns and geopolitical tensions such as those between Russia and Ukraine have created similar volatility in the price of fuel oil used by our marine customers, including low-sulfur fuel oil. A reduction in the price of low-sulfur fuel oil could negatively affect the demand for our marine scrubber systems, which could impact our sales of marine scrubbers and our operating results.

We may be adversely affected by global and regional economic conditions and legislative, regulatory and political developments.

We sell our products around the world, and we expect to continue to derive a substantial portion of sales from outside the U.S. The uncertain macroeconomic environment caused by the prolonged outbreak of COVID-19 may adversely affect our results and could have a negative impact on demand for our products. Customers or suppliers may experience cash flow problems and as a result, may modify, delay or cancel plans to purchase our products, and suppliers may significantly and quickly increase their prices or reduce their output. Additionally, if customers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, amounts owed to us. Any inability of current and/or potential customers to purchase our products and/or to pay us for our products may adversely affect our sales, earnings and cash flow. Sales and earnings could also be affected by our ability to manage the risks and uncertainties associated with the application of local legal requirements or the enforceability of laws and contractual obligations, trade protection measures, changes in tax laws, regional political instability, war, terrorist activities, severe or prolonged adverse weather conditions and natural disasters as well as health epidemics or pandemics.

Our success will depend, to a large degree, on the expertise and experience of the members of our management team, the loss of whom could have a material adverse effect on our business.

Our success is, to a large degree, dependent upon the expertise and experience of the management team and its ability to attract and retain qualified personnel who are technically proficient. The loss of the services of one or more of such personnel could have a material adverse effect on our business. Our business may be adversely affected if we are unable to continue to attract and retain such personnel.

We will need to add qualified additional personnel as we expand our business, and we may not be able to employ such persons, which could affect our ability to expand and have a material adverse effect on our business.

In order to expand our product offerings and customer base, we will need to hire additional qualified personnel. We may not be able to identify such persons, and even if we identify them in periods with low unemployment and increased wage inflation, we may not have the funds or ability to employ them, which could have a material adverse effect on our business. 

Future growth of our business depends in part, on the availability of funding for emissions control programs as well as the enforcement of existing emissions-related environmental regulations and further tightening of emission standards worldwide, all of which are beyond our control and the lack of which could negatively affect our future growth.

Future growth of our business depends in part on the availability of funding for emissions control programs, which can be affected by economic as well as political reasons that are beyond our control. If such funding is not available, or delayed, it can negatively affect our future growth prospects. In addition to funding, we also expect that our future business growth will be driven, in part, by the enforcement of existing emissions-related environmental regulations and tightening of emissions standards worldwide, where regulations and standards are frequently contested in litigation. For example, our ability to expand our business in the marine industry is dependent on the effective implementation of IMO 2020, which requires the burning of low-sulfur oil for marine vessels or the inclusion of marine scrubber technology. During the IMO meeting in November 2021, a number of proposals for further mid-term GHG reduction measures were discussed, including market-based measures, to address GHG emissions from shipping, as well as a proposal to establish an International Maritime Research and Development Board; however no immediate regulation was imposed. If existing regulations and emissions standards do not continue to become stricter, are loosened or are not enforced by governmental authorities due to commercial and business pressure, economic conditions or otherwise, it could have a material adverse effect on our business, operating results, financial condition and long-term prospects.

If we are unable to manage our expected growth, our business may be materially and adversely affected.

We expect to expand our operations by increasing our internal resources, making acquisitions and entering into new markets. The growth of our business could place significant strain on our management, operational and financial resources. To manage our future growth, we could be required to improve existing or implement new operational or financial systems, procedures and controls as well as to expand, train and manage a growing employee base. Our failure to accomplish any of these tasks could materially and adversely affect our business. Even if we are successful in integrating future acquisitions into our existing operations, we may not derive the benefits, such as operational or administrative synergies, that we expected from such acquisitions, which may result in the investment of our capital resources without realizing the expected returns on such investment. We also may not recognize the anticipated benefits of completed dispositions or other divestitures we may pursue in the future.

We face constant changes in governmental standards by which our products are evaluated, and if we cannot meet any such changes, some of our products could become obsolete, which could have a material adverse effect on our business.

We believe that due to the intensifying focus on the environment and clean air and water standards throughout the world, new requirements to adhere to more stringent regulations are possible in the future as governmental agencies seek to promote clean air and water among new product certifications. In the event that our products fail to meet these evolving standards, some or all of our products may become obsolete, which could have an adverse effect on our business, operating results, financial condition and long-term prospects.

Our inability to protect our intellectual property rights could negatively affect our business and results of operations.

Our ability to compete effectively depends in part upon developing, maintaining and/or protecting intellectual property rights relevant to our re-crystallized silicon carbide product forms, applications, and manufacturing processes. We rely principally on a combination of patent protection, trade secrets, confidentiality and non-disclosure agreements, and trusted business relationships to establish, maintain and protect the intellectual property rights relevant to our business. These measures, however, may not be adequate in every given case to permit us to gain or retain any competitive advantage, particularly in those countries where the laws do not protect our proprietary rights as fully as in the United States. In particular, because silicon carbide is a well-known material (developed over 100 years ago), and there has been extensive research, development and publication related to this material and its wide range of applications, obtaining intellectual property rights to key elements of silicon carbide technology can be challenging. Accordingly, at least some of the technology employed in our manufacture of re-crystallized silicon carbide products is not protected by patents.

Where we consider it appropriate, we seek patent protection in the United States and other countries on technologies used in, or relating to, our re-crystallized silicon carbide product forms, applications, and manufacturing processes. The issuance of a patent is not conclusive as to its scope, validity, and enforceability. Thus, any patent or patent application which may issue into a patent held by us could be challenged, invalidated or held unenforceable in litigation or proceedings before the U.S. Patent and Trademark Office and/or other patent tribunals or circumvented by others. No consistent policy regarding the breadth of patent claims has emerged to date in the United States, and the landscape could become more uncertain in view of future rule changes by the United States Patent and Trademark Office, the introduction of patent reform legislation and decisions in patent law cases by United States federal courts. The patent landscape outside the United States is even less predictable. As a result, the validity and enforceability of patents cannot be predicted with certainty. In addition, we may fail to apply for patents on important technologies or product candidates in a timely fashion, if at all, and our existing and future patents may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products or technologies, especially given the long history of silicon carbide development. 

Our patent strategy involves complex legal and factual questions. Our ability to maintain and solidify our proprietary technology may depend in part upon our success in obtaining patent rights and enforcing those rights once granted or licensed. We do not know whether any of our pending patent applications will result in the issuance of any patents. Our issued patents and those that may be issued in the future may be challenged, invalidated, rendered unenforceable or circumvented, which could limit our ability to prevent competitors from marketing similar or related products, or shorten the term of patent protection that we may have for our products, processes and enabling technologies. In addition, the rights granted under any issued patents may not provide us with competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies, duplicate technology developed by us or otherwise possess intellectual property rights that could limit our ability to manufacture our products and operate our business. 

We also rely on trade secret protection for our confidential and proprietary information. Trade secrets, however, can be difficult to protect. We may not be able to maintain our technology or know-how as trade secrets, and competitors may develop or acquire equally valuable or more valuable technology or know-how related to the manufacture of comparable silicon carbide products. We also seek to protect our confidential and proprietary information, in part, by requiring all employees, consultants and business partners to execute confidentiality and/or nondisclosure agreements upon the commencement of any employment, consulting arrangement or engagement with us. These agreements generally require that all confidential and proprietary information developed by the employee, consultant, or business partner, or made known to the employee, consultant or business partner by us, during the course of the relationship with us, be kept confidential and not disclosed to third parties. These agreements may be breached and may not provide adequate remedies in the event of breach. To the extent that our employees, consultants, or business partners use intellectual property owned by others in their work for and/or with us, disputes could arise as to the rights in related or resulting technologies, know-how or inventions. Moreover, while we also require customers and vendors to execute agreements containing confidentiality and/or nondisclosure provisions, we may not have obtained such agreements from all of our customers and vendors. In addition, our trade secrets may otherwise become known or be independently discovered by competitors, customers, or vendors. Such customers or vendors may also be subject to laws and regulations that require them to disclose information that we would otherwise seek to keep confidential.

Moreover, others may independently develop and obtain patents covering technologies that are similar or superior to the product forms, applications, or manufacturing processes that we employ. If that happens, we may need to obtain licenses for these technologies and may not be able to obtain licenses on reasonable terms, if at all, which could limit our ability to manufacture our future products and operate our business. In addition, third parties could utilize our intellectual property rights in territories where we do not have intellectual property protection. Such third parties may then try to import products made using our intellectual property rights into the United States or other countries, which could have a material adverse effect on our business.

Our contracts with third parties could negatively affect our intellectual property rights.

To further strengthen our product development efforts, we continue to work closely with customers, the Danish government and other third parties to research and develop advancements in silicon carbide product forms, applications, manufacturing processes and related products and technologies. We have entered into agreements with private third parties and have been awarded a research and development contract with the Danish government to independently and jointly research, design and develop new devices and systems that incorporate our silicon carbide technologies. We expect to enter into similar private agreements and be awarded similar government contracts in the future. In some instances, the research and development activities that we conduct under these contracts may produce intellectual property to which we may not have ownership or exclusive rights and will be unable to protect or monetize. Furthermore, there could be disputes between us and a private third party as to the ownership rights to any inventions that we develop in collaboration with such third party. Any such dispute may cause us to incur substantial costs and could place a significant strain on our financial resources, divert the attention of management from our core business or harm our reputation. 

We could become subject to intellectual property litigation that could be costly, limit or cancel our intellectual property rights, divert time and efforts away from business operations, require us to pay damages and/or otherwise have an adverse material impact on our business.

The success of our business is highly dependent on protecting our intellectual property rights. Unauthorized parties may attempt to copy or otherwise obtain and use our products and/or enabling technologies. Policing the unauthorized use of our intellectual property rights is difficult and expensive, as is enforcing these rights against unauthorized use by others. Identifying unauthorized use of our intellectual property rights is difficult because we may be unable to monitor the processes and/or materials being employed by other parties. The steps we have taken may not prevent unauthorized use of our intellectual property rights, particularly in foreign countries where enforcement of intellectual property rights may be more difficult than in the United States.

Our continued commercial success will also depend in part upon not infringing the patents or violating the intellectual property rights of third parties. We are aware of patents and patent applications generally relating to aspects of our technologies filed by, and issued to, third parties. Nevertheless, we cannot determine with certainty whether such patents or patent applications of other parties may materially affect our ability to conduct our business. There may be existing patents of which we are unaware that we may inadvertently infringe, resulting in claims against us or our customers. In the event that the manufacture, use and/or sale of our products or processes is challenged, or if our product forms or processes conflict with the patent rights of others, third parties could bring legal actions against us or our customers in the United States, Europe or other countries, claiming damages and seeking to enjoin the manufacturing and/or marketing of our products. Additionally, it is not possible to predict with certainty what patent claims may issue from any relevant third-party pending patent applications. Third parties may be able to obtain patents with claims relating to our product forms, applications and/or manufacturing processes which they could attempt to assert against us or our customers.

In either case, litigation may be necessary to enforce, protect or defend our intellectual property rights or to determine the validity and scope of the intellectual property rights of others. Any litigation could be unsuccessful, cause us to incur substantial costs, divert resources and the efforts of our personnel away from daily operations, harm our reputation and/or result in the impairment of our intellectual property rights. In some cases, litigation may be threatened or brought by a patent holding company or other adverse patent owner who has no relevant product revenues and against which our patents may provide little or no deterrence. If we are found to infringe any patents, we could be required to (1) pay substantial monetary damages, including lost profits, reasonable royalties and/or treble damages if an infringement is found to be willful and/or (2) totally discontinue or substantially modify any products or processes that are found to be in violation of another party’s intellectual property rights. If our competitors are able to use our technology without payment to us, our ability to compete effectively could be harmed.

We face competition and technological advances by competitors, which could adversely affect the sales of our products.

The growth of our Company depends in part on maintaining and growing the sales of our current products in existing and new markets, but also in developing new products and technologies. There is significant competition among companies that provide solutions for pollutant emissions from diesel engines and water purification solutions. Several companies market products that compete directly with our products. Other companies offer products that potential customers may consider to be acceptable or superior alternatives to our products and services, including products that are verified by the Environmental Protection Agency or other environmental authorities. We face direct competition from companies with greater financial, technological, manufacturing and personnel resources. Newly developed products could be more effective and cost-efficient than our current or future products.

Failure to obtain adequate supplies of raw materials or failure to obtain raw materials at affordable prices could negatively affect our ability to supply products to our customers and negatively affect our profit margins.

We use silicon carbide, steel, plastic, platinum and palladium in the manufacture of our products. As other industries develop products utilizing silicon carbide, we may not be able to obtain adequate supplies of silicon carbide required for the manufacture of our existing and future products that would prevent us from supplying products to our customers and materially affect our business. Furthermore, any increased demand for, the raising of tariff rates on, or an increase of non-tariff trade barriers that apply to silicon carbide, steel, plastic, platinum, or palladium could increase the price we must pay to obtain it and could adversely affect our profitability, which would have an adverse effect on our financial results.

We may rely on subcontractors to meet current demand for our products, and we may need to obtain additional manufacturing capacity in order to increase production of our existing products or to produce our proposed new products, the failure of which could have a material adverse effect on our operations.

We may not have sufficient internal manufacturing capacity to meet the current demand for our products, and we may need to rely on subcontractors to enable us to meet this demand. Since we may rely on our subcontractors for a significant amount of our production capacity, the loss of the services of our subcontractors would have a material adverse effect on our business. Our plans for the growth of our business rely upon increasing sales of our existing products and systems and developing and marketing new products. We may not have adequate internal manufacturing facilities to substantially increase production of our products, and obtaining additional manufacturing capacity in-house could require substantial capital expenditures. We may not have the capital resources to obtain or construct new facilities to expand manufacturing capacity and meet increasing demand for our products, which could have a material adverse effect on our operations. Conversely, any significant decrease in demand for our products could create idle plant capacity and an inability to cover fixed costs, which could adversely impact our results of operations and financial condition.

Foreign currency fluctuations could adversely impact financial performance.

Our reporting currency is the United States Dollar ($). Because of our activities in Denmark, the European Continent, China, and other countries, we are exposed to fluctuations in foreign currency rates. Most income and expense related transactions are denominated in other currencies than the reporting currency, and furthermore, a certain portion of the excess cash balances may be held in other currencies than the reporting currency or in bank accounts outside the United States, causing risks of currency fluctuations when translating balances to the official currency rate at the end of the reporting period. We may manage the risk to such exposure by active cash flow management, and in some cases, by entering into foreign currency futures and option contracts; however, we can make no assurance that such actions will be sufficient to offset a material adverse effect on our operations in the future. As of December 31, 2021 and 2020 we have not entered into any derivate contracts to hedge our currency exposure.

Any liability for environmental harm or damages resulting from technical faults or failures of our products could be substantial and could materially adversely affect our business and results of operations.

Customers rely upon our products to meet emissions control standards imposed upon them by the government. Failure of our products to meet such standards could expose us to claims from customers. Our products are also integrated into goods used by consumers, and therefore a malfunction or the inadequate design of our products could result in product liability claims. Any liability for environmental harm or damages resulting from technical faults or failures could be substantial and could materially adversely affect our business and results of operations. In addition, a well-publicized actual or perceived problem could adversely affect the market’s perception of our products, which would materially impact our financial condition and operating results.

We could become liable for damages resulting from our manufacturing activities, which could have a material adverse effect on our business or cause us to cease operations.

The nature of our manufacturing operations exposes us to potential claims and liability for environmental damage, personal injury, loss of life and damage to, or destruction of, property. Our manufacturing operations are subject to numerous laws and regulations that govern environmental protection and human health and safety. These laws and regulations have changed frequently in the past, and it is reasonable to expect additional and more stringent changes in the future. Our manufacturing operations may not comply with future laws and regulations, and we may be required to make significant unanticipated capital and operating expenditures to bring our operations within compliance with such evolving regulations. If we fail to comply with applicable environmental laws and regulations, manufacturing guidelines, and workplace safety requirements, governmental authorities may seek to impose fines and penalties on us or to revoke or deny the issuance or renewal of operating permits, and private parties may seek damages from us. Under such circumstances, we could be required to curtail or cease operations, conduct site remediation or other corrective action, or pay substantial damage claims for which we may not have sufficient or any insurance coverage for claims.

A significant portion of our assets and some of our officers and directors may be located outside of the United States; therefore, it may be difficult for an investor to enforce within the United States any judgments obtained against us or such officers and directors.

A significant portion of our assets are located outside of the United States. In addition, the majority of our officers and potentially some of our directors are nationals and/or residents of countries other than the United States, and all or a substantial portion of such persons’ assets are located outside the United States. As a result, it may be difficult for an investor to affect service of process or enforce within the United States any judgments obtained against us or such officers or directors, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. In addition, there is uncertainty as to whether the courts of other jurisdictions would recognize or enforce judgments of United States courts obtained against us or our directors and officers predicated upon the civil liability provisions of the securities laws of the United States or any state thereof, or be competent to hear original actions brought in other jurisdictions against us or such officers and directors predicated upon the securities laws of the United States or any state thereof. 

We have a plan to establish a joint venture in the Middle East and may engage in additional collaborations, joint ventures, or strategic alliances in the future, and we may not realize the benefits of such arrangements.

LiqTech, has signed a joint venture agreement to supply and operate water treatment systems for oil and gas producers in the Middle East with a local company. We expect to deliver technological know-how, design of water treatment systems and components to support potential projects in the Middle East. The joint venture agreement is structured as a jointly owned limited liability company incorporated under the laws in the local country, with LiqTech Water Projects holding 49% of the shares. All profits of the company are to be allocated proportionally to the ownership share, and none of the parties are liable for the company’s liabilities towards third parties. As of year-end 2021, the joint venture was not legally established.

Additionally, from time to time, we may enter into other joint ventures with other entities. Establishment of a joint venture involves significant risks and uncertainties, including (i) our inability to cooperate with our local partner, (ii) our local partner having economic, business, or legal interests or goals that are inconsistent with ours, and (iii) the potential that our local partner may be unable to meet its economic or other obligations, which may require us to fulfill those obligations alone. In any joint venture we engage in, we will rely on our local partner for the implementation of much of any such joint venture operation, and the success of any such operation is thus not entirely within our control. Any failure or perceived failure of a joint venture may have a material impact on our operations and financial condition.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results, and current and potential stockholders may lose confidence in our financial reporting.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filing if such controls were unable to provide assurance that a material error would be prevented or detected in a timely manner. We have an ongoing program to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controls design and test the system and process controls necessary to comply with these requirements. If our internal controls over financial reporting are determined to be ineffective, resulting in material weaknesses and/or significant deficiencies; investor perceptions regarding the reliability of our financial statements may be adversely affected, which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

In Item 9A, we disclose that, with respect to the standards of Sarbanes-Oxley Section 404 and the internal controls standard to which we are subjected, we reported material weaknesses in our internal controls over financial reporting. For additional information on this item, please see Item 9A. Controls and Procedures.

Although we believe our historical efforts have strengthened our internal control over financial reporting (and we concluded that our financial statements were reliable, notwithstanding the material weakness we reported), we cannot be certain that our revised internal control practices will ensure that we will have or maintain adequate internal control over financial reporting in future periods. Any failure to have or maintain such internal controls could adversely impact our ability to report our financial results accurately and on a timely basis. If our financial statements are not accurate, investors may not have a complete understanding of our operations.

We may have risks associated with security of our information technology systems.

We make significant efforts to maintain the security and integrity of our information technology systems and data. Despite significant efforts to create security barriers to such systems, it is virtually impossible for us to entirely mitigate this risk. There is a risk of industrial espionage, cyber-attacks, misuse or theft of information or assets, or damage to assets by people who may gain unauthorized access to our facilities, systems, or information. Such cybersecurity breaches, misuse, or other disruptions could lead to the disclosure of confidential information; improper usage and distribution of our intellectual property; theft, manipulation, and destruction of private and proprietary data; and production downtimes. Although we actively employ measures to prevent unauthorized access to our information systems, preventing unauthorized use or infringement of our rights is inherently difficult. These events could adversely affect our financial results, and any legal action in connection with any such cybersecurity breach could be costly and time-consuming, may divert management’s attention and adversely affect the market’s perception of us and our products. In addition, we must frequently expand our internal information system to meet increasing demand in storage, computing and communication, which may result in increased costs. Our internal information system is expensive to expand and must be highly secure due to the sensitive nature of our customers’ information that we transmit. Building and managing the support necessary for our growth places significant demands on our management and resources. These demands may divert such resources from the continued growth of our business and implementation of our business strategy.

RISKS RELATED TO OUR COMMON STOCK

Future equity financings or convertible debt would dilute your ownership and could adversely affect your common stock ownership rights in comparison with those of other security holders.

Our board of directors has the power to issue additional shares of common or preferred stock without stockholder approval. In general, stockholders do not have preemptive rights to any common stock issued by us in the future; therefore, stockholders may experience additional dilution of their equity investment if we issue additional shares of common stock in the future, including shares issuable under equity incentive plans, or if we issue securities that are convertible into shares of our common stock. 

If additional funds are raised through the issuance of equity or convertible debt securities, the percentage of ownership of our existing stockholders will be reduced, and such newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we issue additional common stock or securities convertible into common stock, such issuance will reduce the proportionate ownership and voting power of each other stockholder. In addition, such stock issuances might result in a reduction of the market value of our common stock, which could make our stock unattractive to existing stockholders.

Provisions in our articles of incorporation and bylaws could discourage a change in control, or an acquisition of us by a third party, even if the acquisition would be favorable to you, thereby adversely affecting existing stockholders.

Our articles of incorporation and bylaws contain provisions that may have the effect of making it more difficult or delaying attempts by others to obtain control of our Company, even when these attempts may be in the best interests of stockholders. For example, our articles of incorporation authorize our Board of Directors, without stockholder approval, to issue one or more series of preferred stock, which could have voting and conversion rights that adversely affect or dilute the voting power of the holders of common stock. These provisions and others that could be adopted in the future could deter unsolicited takeovers or delay or prevent changes in our control or management, including transactions in which stockholders might otherwise receive a premium for their shares over then-current market prices. These provisions may also limit the ability of stockholders to approve transactions that they may deem to be in their best interests.

There is limited trading volume of our common stock, which could make it difficult for you to liquidate an investment in our common stock in a timely manner.

Since April 16, 2019, our common stock has been traded on Nasdaq Capital Market under the ticker LIQT. Because there is limited volume in our common stock, investors may not be able to liquidate their investments when they desire to do so.

In addition, if we fail to meet the criteria set forth in SEC and Nasdaq Capital Market rules and regulations, various requirements would be imposed by law on broker-dealers who sell our securities to persons other than established customers and accredited investors. Consequently, such regulations may deter broker-dealers from recommending or selling our common stock, which may further affect its liquidity.

If securities analysts do not publish research or reports about our business or if they downgrade us or our sector, the price of our common stock could decline.

The trading market for our common stock will depend in part on research and reports that industry or financial analysts publish about us or our business. Furthermore, if one or more of the analysts who cover us downgrades us, the industry in which we operate, or the stock of any of our competitors, the price of our common stock may decline. If one or more of these analysts ceases coverage altogether, we could lose visibility, which could also lead to a decline in the price of our common stock. 

The market price of our common stock has been and may continue to be volatile.

The market price of our common stock has been volatile and fluctuates widely in response to various factors that are beyond our control. The price of our common stock is not necessarily indicative of our operating performance or long-term business prospects. In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock. Factors such as the following could cause the market price of our common stock to fluctuate substantially:

The realization of any of these risks and other factors beyond our control could cause the market price of our common stock to decline significantly. In particular, the market price of our common stock may be influenced by changes in governmental regulations regarding diesel particle emissions and marine wastewater because demand for our products and services is closely related to those regulations. The stock market in general experiences, from time to time, extreme price and volume fluctuations. Periodic and/or continuous market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility may be worse if the trading volume of our common stock is low.

Future sales of our common stock, or the perception that future sales may occur, may cause the market price of our common stock to decline.

If any significant number of our outstanding shares are sold, such sales could have a depressive effect on the market price of our stock. We are unable to predict the effect, if any, that the sale of shares, or the availability of shares for future sale, will have on the market price of the shares prevailing from time to time. Sales of substantial amounts of shares in the public market, or the perception that such sales could occur, could depress prevailing market prices for the shares. Such sales may also make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that we deem appropriate.

The Company is considered a “smaller reporting company” and is exempt from certain disclosure requirements, which could make our common stock less attractive to potential investors.

As a “smaller reporting company” (as defined in Rule 12b-2 of the Securities Exchange Act of 1934 (the “Exchange Act”)) we are not required and may not include a Compensation Discussion and Analysis section in our proxy statements; we provide only three years of business information; provide fewer years of selected financial data; and have other “scaled” disclosure requirements that are less comprehensive than issuers that are not “smaller reporting companies,” which could make our stock less attractive to potential investors and could make it more difficult for shareholders to sell their shares.

We have no current plan to pay dividends on our common stock, and investors may lose the entire amount of their investment.

We have no current plans to pay dividends on our common stock; therefore, investors will not receive any funds absent a sale of their shares. We cannot assure investors of a positive return on their investment when they sell their shares, nor can we assure that investors will not lose the entire amount of their investment.

PUBLIC COMPANY RISK FACTORS

We will continue to incur significant costs as a result of operating as a public company, and our management may be required to devote substantial time to compliance initiatives that ultimately could have a material adverse effect on our financial condition and results of operations.   

As a public company, we expect to continue to incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC, have imposed various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls as well as mandating certain corporate governance practices. Our management and other personnel will continue to devote a substantial amount of time and financial resources to these compliance initiatives.

As a “smaller reporting company” we are still able to take advantage of certain exceptions available to both emerging growth companies and smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and the exemption from providing a “Compensation Discussion and Analysis” section in our proxy statements; providing only three years of business information; and other “scaled” disclosure requirements that are less comprehensive than issuers that are not smaller reporting companies. 

If we fail to staff our accounting and finance function adequately or maintain internal control systems adequate to meet the demands that are placed upon us as a public company, we may be unable to report our financial results accurately or in a timely manner and our business and stock price may suffer. The costs of being a public company, as well as diversion of management’s time and attention, may have a material adverse effect on our future business, financial condition and results of operations.

Our actual or perceived failure to adequately protect personal data could adversely affect our business, financial condition, and results of operations.

A wide variety of provincial, state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. Further, our legal and regulatory obligations in foreign jurisdictions are subject to unexpected changes, including the potential for regulatory or other governmental entities to enact new or additional laws or regulations, to issues rulings that invalidate prior laws or regulations, or to increase penalties significantly. Compliance with these laws and regulations can be costly and can delay or impede the development and offering of new products and services. 

For example, the General Data Protection Regulation, which became effective in May 2018, imposes more stringent data protection requirements, and provides for significantly greater penalties for noncompliance, than the European Union laws that previously applied. Additionally, California recently enacted legislation, the California Consumer Privacy Act, which became effective January 1, 2020. We may also be subject to additional obligations relating to personal data by contract that industry standards apply to our practices. Our actual or perceived failure to comply with applicable laws and regulations or other obligations to which we may be subject relating to personal data, or to protect personal data from unauthorized access, use, or other processing, could result in enforcement actions and regulatory investigations against us, claims for damages by customers and other affected individuals, fines, damage to our reputation, and loss of goodwill, any of which could have a material adverse effect on our operations, financial performance, and business. Further, evolving and changing definitions of personal data and personal information, including the classification of IP addresses, machine identification information, location data, and other information, may limit or inhibit our ability to operate or expand our business, including limiting business relationships and partnerships that may involve the sharing or uses of data, and may require significant costs, resources, and efforts in order to comply.

Changes in U.S. Generally Accepted Accounting Principles (“GAAP”) could adversely affect our financial results and may require significant changes to our internal accounting systems and processes.

We prepare our consolidated financial statements in conformity with GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the SEC and various bodies formed to interpret and create appropriate accounting principles and guidance. The FASB periodically issues new accounting standards on a variety of topics. For information regarding new accounting standards, please refer to Note 1, “Description of Business and Significant Accounting Policies – Recent Accounting Pronouncements,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K. These and other such standards generally result in different accounting principles, which may significantly impact our reported results or could result in variability of our financial results.

In preparing our financial statements we make certain assumptions, judgments and estimates that affect amounts reported in our consolidated financial statements, which, if not accurate, may significantly impact our financial results.

We make assumptions, judgments and estimates for a number of items, including the fair value of financial instruments, goodwill, long-lived assets and other intangible assets; the realizability of deferred tax assets; the recognition of revenue and the fair value of stock awards; and others. We also make assumptions, judgments and estimates in determining the accruals for employee-related liabilities, including commissions and variable compensation, and in determining the allowance or provisions for uncertain tax positions, doubtful accounts, excess or obsolete inventory, and legal contingencies. These assumptions, judgments and estimates are drawn from historical experience and various other factors that we believe are reasonable under the circumstances as of the date of the consolidated financial statements. Actual results could differ materially from our estimates, and such differences could significantly impact our financial results.

Our business could be negatively affected as a result of the actions of activist shareholders, and such activism could impact the trading value of our securities.

In recent years, shareholder activists have become involved in numerous public companies. Shareholder activists frequently propose to involve themselves in the governance, strategic direction and operations of the Company. Such proposals may disrupt our business and divert the attention of our Board of Directors, management and employees, and any perceived uncertainties as to our future direction resulting from such a situation could result in the loss of potential business opportunities, interfere with our ability to execute our strategic plan, be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel and business partners, all of which could adversely affect our business. A proxy contest for the election of directors at our annual meeting could also require us to incur significant legal fees and proxy solicitation expenses. In addition, actions of activist shareholders may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Our business could be negatively impacted the by surge in geopolitical unrest and associated market turmoil negatively impacting both financial markets.

Increased geopolitical tensions and potential prolonged inflationary pressure combined with increased commodity prices and general volatility across financial markets could negatively impact demand for our products and services due to temporary or even permanent reductions in investments across the global transportation, shipping, and energy industries. The relevance and economic benefits of our systems may also be undermined by a delayed introduction or compliance with both environmental and regulatory efforts. Furthermore, potential sanctions imposed on select countries, could adversely affect our supply chain and overall demand, thus reducing our ability to timely source raw materials and deliver finished goods and services to our clients.

Results of Operations

Results of Operations for the Year Ended December 31, 2021 Compared to the Year Ended December 31, 2020 

The following table sets forth our revenues, expenses and net income for the years ended December 31, 2021 and 2020 in U.S. dollars, except for percentages.  

Revenues

Revenue for the year ended December 31, 2021 was $18,273,442 compared to $22,526,201 for the same period in 2020, representing a decrease of $4,252,759, or 19%. The change in revenue mainly consists of a decrease in sales of liquid filters and systems partly offset by an increase in sales of DPFs and plastics.

The decrease in sales of liquid filters and water treatment systems is a result of the negative impact of the ongoing COVID-19 pandemic, but also increased supply chain restrictions and general market volatility, which has resulted in significant restrictions and business limitations across the globe and caused a substantial decline in the demand and delivery of water treatment systems for the marine scrubber industry. The demand for our DPFs reflects a continued interest in environmental solutions to reduce global CO2 emissions amid increased political and regulatory efforts.

Furthermore, for the years ended December 31, 2021 and 2020, LiqTech received revenue from government grant projects of $277,428 and $599,102, respectively.

Gross Profit

Gross profit for the year ended December 31, 2021 was $1,576,146 compared to $2,146,682 for the same period in 2020, representing a decrease of $570,536, or approximately 27%. The decrease in gross profit is due to the decline in sales of liquid filters and water treatment systems, for which sales command a higher gross margin. Gross profit was further impacted by increased costs related to decisions made prior to the impact of COVID-19, where the Company had invested in the expansion and improvement of production facilities along with additional employees. Furthermore, increased cost related to the China project ramp-up and changes in sales mix negatively impacted the 2021 gross profit. Included in the gross profit for the year ended December 31, 2021 is depreciation of $1,957,357 compared to $2,204,917 for the same period in 2020.

Expenses

Total operating expenses for the year ended December 31, 2021 were $12,263,470, representing an increase of $1,861,681, or approximately 18%, compared to $10,401,789 for the same period in 2020.

Selling expenses for the year ended December 31, 2021 were $4,564,188 compared to $2,918,418 for the same period in 2020, representing an increase of $1,645,770 or approximately 56%. This change is attributable to the pre-COVID-19 decision to hire new sales employees, for which the average number of sales employees increased from 13 in 2020 to 19 in 2021. Other expenses related to the update of the Company’s website and other marketing materials have also resulted in increased selling expenses.

General and administrative expenses for the year ended December 31, 2021 were $5,836,629 compared to $6,205,040 for the same period in 2020, representing a decrease of $368,411, or 6%. The decrease in general and administrative expenses is attributable to the reduction of administrative employees, for which the average number of employees decreased from 22 in 2020 to 13 in 2021. Included in general and administrative expenses is non-cash compensation expenses of $481,105 and $343,780 for the years ended December 31, 2021 and December 31, 2020, respectively, representing an increase of $137,327, or 40%, attributable to stock grants to members of the Board and management. 

The following is a summary of our non-cash compensation:

Research and development expenses for the year ended December 31, 2021 were $1,862,653 compared to $1,278,331 for the same period in 2020, representing an increase of $584,322, or 46%. This change is attributable to an increase in the average number of employees engaged in research and development activities as the Company focuses on the further development of existing and new products for the marine industry. The average number of employees engaged in research and development activities increased from 14 in 2020 to 17 in 2021.

Other income (expenses)

Total Other income (expense) for the year ended December 31, 2021 was $(502,672) compared to $(2,018,398) for the comparable period in 2020, representing a decrease of $1,515,726, or 75%. Included in the Other income (expenses) for the year ended December 31, 2020 is the negative effect of $901,250 resulting from the fair value remeasurement of the prefunded warrants issued in May 2020. Additionally, the gain on currency transactions from the USD/DKK exchange rate impacted Other income as a gain by $668,255 in 2021 compared to a loss of $(1,469,607) in 2020, representing an increase of $2,137,862. Further, in 2021 interest expenses was $(708,176) compared to $(120,903) in 2020, which together with the Amortization discount of $(835,331), reflects the issuance of the Convertible Note in 2021.

Income taxes provision

The income tax benefit for the year ended December 31, 2021 was $63,036 compared to a benefit of $465,145 for the comparable period in 2020, representing a decrease of $402,109 mainly driven by a reduction in tax credits associated with the Danish research and development activities.

Net Income/(Loss)

Net income/(loss) for the year ended December 31, 2021 was $(11,126,960) compared to $(9,808,360) for the comparable period in 2020, representing an increased loss of $1,318,600.

This change was primarily attributable to the decrease in revenue due to diminished demand for marine scrubbers, higher relative costs of goods sold as a percentage of revenue due to investments in production capacity across our Danish manufacturing facilities and inflationary pressure on both raw materials, electricity and salary related to hourly paid workers. The year-on-year development also reflects continued investments in the global sales organization and the research and development efforts leading to an overall increase in spend compared to 2020.

Liquidity and Capital Resources

Based on the prolonged negative effects of the global pandemic, we are unable to predict the full impact that COVID-19 will have on our long-term financial condition, results of operations, liquidity, and cash flows. Our compliance with the measures implemented to avoid the spread of the virus had a material adverse impact on our financial results since March 2020. Based on current projections, which are subject to numerous uncertainties, including the duration and severity of the pandemic and containment measures along with the effect of these on the industries in which we compete, we believe our cash on hand, as well as our ongoing cash generated from operations, might not be sufficient to cover our capital requirements for the next 12 months from the issuance of this report as we consider further investments to generate revenue growth. In addition, as a result of the reduced order intake, continued supply chain disruptions, and decreased manufacturing levels, our future gross profit will also likely be unfavorably impacted until such time that we are able to operate our manufacturing facilities at higher capacity levels as originally planned prior to the COVID-19 pandemic. Notwithstanding the reduction in our manufacturing levels and continued supply chain disruptions, based on our current rate of production, we believe that we will be able to fulfill most, if not all, of our existing delivery obligations in 2022.

While we anticipate that the foregoing measures are temporary, we cannot predict the specific duration for which these precautionary measures will stay in effect and how our business may be adversely affected as a result of the pandemic’s global economic impact and associated supply chain disruptions. In the future, the pandemic may cause reduced or changed demand characteristics for our products, especially if it results in a global recession or structural shifts in the demand for our products across our end markets. It could also lead to limitations in our ability to produce and ship products caused by governmental actions and regulations to contain the spread of the virus along with disruptions in the global supply chain.

We have historically satisfied our capital and liquidity requirements through offerings of equity instruments, internally generated cash from operations and our available lines of credit. At the filing date, the Company had a line of credit amounting to DKK 20,000,000 ($3,000,000), which is used for a leasing arrangement pertaining to deliveries of high-temp furnaces.

On December 31, 2021, we had cash of $17,489,380 and net working capital of $11,199,258, and on December 31, 2020, we had cash of $13,264,449 and net working capital of $15,839,992. On December 31, 2021, our net working capital decreased by $4,640,734 compared to December 31, 2020, mainly as a result of the current portion of the Convertible Note and lower Accounts payable. This was partly offset by lower Accounts receivable and an increase in cash due to the proceeds from the issuance of a Convertible Note in April 2021.

In connection with certain orders, we provide the customer a working guarantee, a prepayment guarantee or a security bond. For that purpose, we maintain a guaranteed credit line of DKK13,000,000 (approximately $2,000,000). The credit line is secured by a cash deposit of $2,000,000.

Cash Flows

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Cash used by operating activities is net income (losses) adjusted for certain non-cash items and changes in assets and liabilities. Cash used by operating activities for the year ended December 31, 2021 was $7,203,843 compared to cash used by operating activities of $2,598,865 for the year ended December 31, 2020, representing a reduction of $4,604,978. The cash used by operating activities for the year ended December 31, 2021 consists mainly of the net loss for the year of $(11,126,960) adjusted by depreciation and other non-cash related items of $3,992,529. Further, changes in assets and liabilities include decreased Accounts receivables of $971,460, a decline in Contract assets/liabilities of $455,185, and an increase in Accrued expenses of $798,543, offset by a decrease in Accounts payable of $532,718.

Net cash used in investing activities was $1,450,139 for the year ended December 31, 2021 as compared to $4,008,521 for the year ended December 31, 2020, representing a reduction of $2,558,382, or 64%. The investing activities include the purchase of property and equipment, especially related to the Danish manufacturing facilities. For the year ended December 31, 2020, the investments mainly related to the new furnaces in Ballerup.

Cash provided by financing activities was $13,902,999 for the year ended December 31, 2021 as compared to $7,216,902 for the year ended December 31, 2020. This change of $6,686,097 was mainly attributable to the net cash proceeds of $14,283,333 related to the Convertible bond issuance in March 2021 compared to the capital raise in May 2020 of $7,237,127.

Off-Balance Sheet Arrangements

As of December 31, 2021, we had no off-balance sheet arrangements. We are not aware of any material transactions that are not disclosed in our consolidated financial statements.

Critical Accounting Estimates

The methods, estimates, and judgments that we use in applying our accounting policies have a significant impact on the results that we report in our consolidated financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. Our most critical accounting estimates include:

We discuss these policies further below, as well as the estimates and judgments involved. 

Accounts Receivable / Long Term Receivable / Allowance for Doubtful Accounts / Bad Debt

We assess the collectability of accounts receivable and long-term receivable on an ongoing basis and establish an allowance for doubtful accounts when collection is no longer reasonably assured. In establishing the allowance, we consider factors such as known troubled accounts, historical experience, age of receivables, financial and liquidity information that is publicly accessible, and other currently available evidence.

The roll-forward of the allowance for doubtful accounts for the year ended December 31, 2021 and December 31, 2020 was as follows:

Goodwill and Definite-life intangible assets

The Company accounts for Goodwill and definite-life intangible assets in accordance with provisions of the Statement of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles, Goodwill and Other. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead are tested for impairment at least annually in accordance with the provisions of Topic 350. Impairment losses arising from this impairment test, if any, are included in operating expenses in the period of impairment. Topic 350 requires that definite intangible assets with estimable useful lives be amortized over their respective estimated useful lives and reviewed for impairment in accordance with Topic 360, criteria for recognition of an impairment of Long-Lived Assets.

The Company did not record an impairment charge on goodwill during the years ended December 31, 2021 and 2020, as management's estimated fair value of the reporting unit exceeded its carrying value determined during impairment testing in the fourth quarters of 2021 and 2020.

Long-Lived Assets

We assess the impairment of long-lived assets when events or changes in circumstances indicate that the carrying value of the assets or the asset grouping may not be recoverable. Factors that we consider in deciding when to perform an impairment review include significant under-performance of a business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in our use of the assets. We measure the recoverability of assets that will continue to be used in our operations by comparing the carrying value of the asset grouping to our estimate of the related total future undiscounted net cash flows. If an asset grouping’s carrying value is not recoverable through the related undiscounted cash flows, the asset grouping is considered to be impaired. The impairment is measured by comparing the difference between the asset grouping’s carrying value and its fair value.

Impairments of long-lived assets are determined for groups of assets related to the lowest level of identifiable independent cash flows. Due to our asset usage model and the interchangeable nature of our ceramic filter manufacturing capacity, we must make subjective judgments in determining the independent cash flows that can be related to specific asset groupings. In addition, as we make manufacturing process conversions and other factory planning decisions, we must make subjective judgments regarding the remaining useful lives of assets, primarily process-specific filter manufacturing tools and building improvements. If we determine that the useful lives of assets are shorter than we had originally estimated, we accelerate the rate of depreciation over the assets’ new, shorter useful lives.

Management has analyzed the impact of the COVID-19 pandemic on its financial statements as of December 31, 2021 and has determined that the changes to its significant judgements and estimates did not have a material impact with respect to goodwill, intangible assets or long-lived assets. During the years ended December 31, 2021 and 2020, no impairment charge of long-lived assets has been recorded. 

Revenue Recognition

On January 1, 2018, the Company adopted Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers,” which includes clarifying ASUs issued in 2015, 2016 and 2017 (“new revenue standard”). The new revenue standard was applied to all open revenue contracts using the modified retrospective method as of January 1, 2018.

The Company sells products throughout the world; sales by geographical region are as follows:

The Company’s sales by product line are as follows for the years ended December 31, 2021 and 2020:

For membranes, diesel particulate filters and plastic components, revenue is recognized when performance obligations under the terms of a contract with the customer are satisfied, which occurs when control of the product transfers to the customer or when services are rendered by the Company. The majority of the Company's sales contracts contain performance obligations satisfied at a point in time when title and risks and rewards of ownership have transferred to the customer. This generally occurs when the product is shipped or accepted by the customer.  Revenue for service contracts is recognized as the services are provided. Revenue is measured as the amount of consideration expected to be received in exchange for transferring the goods or providing services. The satisfaction of performance obligations under the terms of a revenue contract generally gives rise to the right for payment from the customer. The Company's standard payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and when payment is due is not significant. Pre-payments received prior to satisfaction of performance obligations are recorded as a Contract liability. Given the insignificant days between revenue recognition and receipt of payment, financing components do not exist between the Company and its customers.

For contracts with customers that include multiple performance obligations, judgment is required to determine whether performance obligations specified in these contracts are distinct and should be accounted for as separate revenue transactions for recognition purposes. For such arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using expected cost-plus margin.

System sales are recognized when the Company transfers control based upon signed acceptance of the system by the customer, which typically occurs upon shipment of the system in accordance with the terms of the contract. In connection with the system sale, it is normal procedure to issue a FAT (Factory Acceptance Test) stating that the customer has accepted the performance of the system as it is being shipped from our production facility in Hobro. As part of the performance obligation, the customer is normally offered commissioning services (final assembly and configuration at a place designated by the customer), and this commissioning is therefore considered a second performance obligation and is valued at cost, with the addition of a standard gross margin. This second performance obligation is recognized as revenue at the time of provision of the commissioning services together with the cost incurred. Part of the invoicing to the customer is also attributed to the commissioning, and at transfer of the control of the system (i.e. the first performance obligation), some of the invoicing will still be awaiting commissioning and is therefore recognized as Contract assets.

Aftermarket sales represent parts, extended warranties, and maintenance services. For the sale of aftermarket parts, the Company transfers control and recognizes revenue when parts are shipped to the customer. When customers are given the right to return eligible parts and accessories, the Company estimates the expected returns based on an analysis of historical experience. The Company adjusts estimated revenues at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. The Company recognizes revenue for extended warranty and maintenance agreements based on the standalone selling price over the life of the contract.

The Company has received long-term contracts for grants from government entities for the development and use of silicon carbide membranes in various water filtration and treatment applications and historically in the installation of various water filtrations systems. We measure transfer of control of the performance obligation on long-term contracts utilizing the cost-to-cost measure of progress, with cost of revenue including direct costs such as labor and materials. Under the cost-to-cost approach, the use of estimated costs to complete each performance obligation is a significant variable in the process of determining recognized revenue and a significant factor in the accounting for such performance obligations. The timing of when we bill our customers is generally dependent upon advance billings terms, milestone billings based on completion of certain phases of the work or when services are provided, or when products are shipped. Projects with performance obligations recognized over time that have costs and estimated earnings recognized to date in excess of cumulative billings are reported on our balance sheet as Contract assets. Projects with performance obligations recognized over time that have cumulative billings in excess of costs and estimated earnings recognized to date are reported on our balance sheet as Contract liabilities.

Contract assets are the Company’s rights to consideration in exchange for goods or services and is recognized when a performance obligation has been satisfied but has not yet been billed. Contract assets are transferred to receivables when the right to consideration is unconditional and billed per the terms of the contractual agreement. Contract liabilities are payments received from customers prior to satisfaction of performance obligations, and these balances are typically related to prepayments for third-party expenses that are incurred shortly after billing. Contract liabilities also include deferred revenue related to the second performance obligation stated under Revenue Recognition, where the obligation is attributed to the commissioning of the water treatment system.

The roll-forward of Contract assets / liabilities for the periods ended December 31, 2021 and December 31, 2020 is as follows: 

Income Taxes

We must make estimates and judgments in determining the provision for income taxes for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, benefits, and deductions and in the calculation of certain tax assets and liabilities that arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. Significant changes in these estimates may result in an increase or decrease to our tax provision in a subsequent period.

We must assess the likelihood that we will be able to recover our deferred tax assets. If recovery is not likely, we must increase our provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable. We believe that we will ultimately recover the deferred tax assets recorded on our consolidated balance sheets. Should there be a change in our ability to recover our deferred tax assets, however, our tax provision would increase in the period in which we determined that the recovery was not likely. Recovery of a portion of our deferred tax assets is impacted by management's plans and methods of allocating research and development costs to the underlying reporting units.

The calculation of our tax liabilities involves uncertainties in the application of complex tax regulations in Denmark and the United States. When a tax position is determined uncertain, we recognize liabilities based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If we determine that a tax position will more likely than not be sustained on audit, the second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as we must determine the probability of various possible outcomes. If uncertainties arise, we re-evaluate the tax positions on a quarterly basis. This evaluation is based on factors such as changes in facts or circumstances, changes in tax law, new audit activity, and effectively settled issues. Determining whether an uncertain tax position is effectively settled requires judgment. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.

Inventory

The valuation of inventory requires us to estimate excess or obsolete inventory as well as inventory that is not of saleable quality. The determination of excess or obsolete inventory requires us to estimate the future demand for our products. The estimate of future demand is compared to work-in-process and finished goods inventory levels to determine the amount, if any, of excess or obsolete inventory. As of December 31, 2021, we had total furnace parts and supplies of $213,224, raw materials of $2,144,076, work-in-process inventory of $1,671,290, total finished goods inventory of $1,660,907 and a reserve for excess and obsolescence of $268,470. The estimated future demand is included in the development of our short-term manufacturing plans to enable consistency between inventory valuation and production decisions. Product-specific facts and circumstances reviewed in the inventory valuation process include a review of the customer base, acceptance of the product by the customer and the various environmental authorities, competitors’ products, as well as an assessment of the selling price in relation to the product cost. If our demand forecast for specific products is greater than actual demand, and we fail to reduce manufacturing output accordingly, we could be required to write off inventory or increase our allowance, which would negatively impact our gross profit.

In order to determine what costs can be included in the valuation of inventory, we must determine normal capacity at our manufacturing, assembly and test facilities, based on historical production, compared to total available capacity. If the factory production is below the established normal capacity level, a portion of our manufacturing overhead costs would not be included in the cost of inventory, and therefore would be recognized as cost of sales in that period, which would negatively impact our gross profit. We refer to these costs as excess capacity charges. The Company has been operating below capacity, and excess capacity charges have been recognized as cost of sales.

Loss Contingencies

We are subject to various legal and administrative proceedings along with asserted and potential claims, accruals related to product warranties and potential asset impairments (loss contingencies) that arise in the ordinary course of business. An estimated loss from such contingencies is recognized as a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a loss contingency is required if there is at least a reasonable possibility that a loss has been incurred. The outcomes of legal and administrative proceedings and claims, and the estimation of product warranties and asset impairments, are subject to significant uncertainty. Significant judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable. To estimate the losses associated with repairing and replacing parts in connection with product warranty, we make judgments with respect to customer claim rates. At least quarterly, we review the status of each significant matter, and we may revise our estimates. These revisions could have a material impact on our results of operations and financial position. 

We are not required to provide quantitative and qualitative disclosures about market risk because we are a smaller reporting company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of LiqTech International, Inc.:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of LiqTech International, Inc. (“the Company”) as of December 31, 2021, and 2020, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2021, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and 2020, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph Regarding Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company incurred a net loss, which raises substantial doubt about its ability to continue as a going concern. Management's plans regarding these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included examining on a test basis, evidence regarding the amounts and disclosures in the financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.  We believe that our audits provide a reasonable basis for our opinion. 

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) related to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgements. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Inventory Costing

As described in Notes 1 and 2 to the consolidated financial statements, the Company uses a standard costing method to value inventory.  Management reviews and assesses the standard costing estimates annually or more frequently in the event circumstances indicate a change in cost structure or material variance from actual has occurred.  In addition to raw materials and labor, the Company applies a production overhead allocation cost to each item.

We identified the auditing of inventory costing as a critical audit matter because of the significant estimates and assumptions management used in the determination of the standard costing allocation and overhead allocations. Performing audit procedures to evaluate the reasonableness of these estimates and assumptions required a high degree of auditor judgment and an increased extent of effort.

Our audit procedures consisted of the following:

Revenue Recognition – Contracts with Multiple Performance Obligations

As described in Note 1 to the consolidated financial statements, the Company has some contracts with customers that contain multiple performance obligations. For these contracts, management accounts for individual performance obligations separately if they are distinct. As described by management, management exercises judgment and uses estimates in order to (1) determine whether performance obligations are distinct and should be accounted for separately; (2) determine the standalone selling price of each performance obligation; (3) allocate the transaction price among the various performance obligations on a relative standalone selling price basis; and (4) determine whether revenue for each performance obligation should be recognized at a point in time or over time. Revenue recognized in 2021 related to contracts with multiple performance obligations was approximately $7.2 million.

We identified the auditing of revenue from contracts with multiple performance obligations as a critical audit matter because there was significant judgments by management in identifying, evaluating and accounting for performance obligations in contracts with multiple performance obligations, which led to significant auditor judgment and effort in performing procedures to evaluate whether contracts with multiple performance obligations were appropriately identified, evaluated and accounted for by management.

Our audit procedures consisted of the following:

Reclassification – Certain amounts presented in previously issued financial statements have been reclassified to be consistent with the current period presentation. In the statement of operations and comprehensive loss, the Company has reclassified the prior year comparative amounts of general and administrative expenses and other expenses to be consistent with the current classification.

Functional Currency / Foreign currency translation -- The functional currency of LiqTech International, Inc., and LiqTech USA, Inc. is the U.S. Dollar. The functional currency of LiqTech Holding, LiqTech Water, LiqTech Plastics, LiqTech Ceramics, LiqTech Water Projects and LiqTech Emission Control is the Danish Krone (“DKK”); the functional currency of LiqTech China is the Renminbi (“RMB”); the functional currency of LiqTech Germany is the Euro; and the functional currency of LiqTech Singapore is the Singapore Dollar. The Company’s reporting currency is the U.S. Dollar for the purpose of these consolidated financial statements. The balance sheet accounts of the foreign subsidiaries are translated into U.S. Dollars at the period-end exchange rates, and all revenue and expenses are translated into U.S. Dollars at the average exchange rates prevailing during the twelve months ended December 31, 2021 and 2020. Translation gains and losses are deferred and accumulated as a component of other comprehensive income (loss) in stockholders’ equity. Transaction gains and losses that arose from exchange rate fluctuations from transactions denominated in a currency other than the functional currency are included in the statement of operations as incurred. 

Significant events -- In March 2020, the World Health Organization declared the outbreak of the novel coronavirus (“COVID-19”) a pandemic, which has resulted in authorities across the globe implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. In response to measures taken by state and local governments in mid- March 2020, we initially elected to temporarily introduce two shifts at our production facilities to minimize the risk of infection and to implement health and safety actions recommended by government and health officials to better protect our employees who are required to be present at our production facilities. In addition, many of our employees have been working remotely for select periods in line with recommendations from the government agencies. Throughout 2021 and up until the date of this report, we are maintaining our focus on securing operational continuity despite the infrequent restrictions imposed on our business from various cycles of the pandemic. We strive to protect our employee by maintaining focus on relevant COVID protective measures including, but limited to, maintaining physical distance, cleaning and disinfection of high-touch surfaces, and a general recommendation to our employees to follow government guidelines on vaccination and testing strategy.

We are unable to accurately predict the full impact that COVID-19 will have on our long-term financial condition, results of operations, liquidity and cash flows, and our compliance with the measures implemented to avoid the spread of the virus did have a material adverse impact on our financial results for the fiscal year 2021. Based on current projections, which are subject to numerous uncertainties, including the duration and severity of the pandemic and containment measures along with the effect of these on the industries in which we compete, we believe our cash on hand, as well as our ongoing cash generated from operations, might not be sufficient to cover our capital requirements for the next 12 months from the issuance of this report as we consider further investments to generate revenue growth. In addition, as a result of the reduced order intake, continued supply chain disruptions, and decreased manufacturing levels, our future gross profit will also likely be unfavorably impacted until such time that we are able to operate our manufacturing facilities at higher capacity levels as originally planned prior to the COVID-19 pandemic. Notwithstanding the reduction in our manufacturing levels and continued supply chain disruptions, based on our current rate of production, we believe that we will be able to fulfill most, if not all, of our existing delivery obligations in 2022.

While we anticipate that the foregoing measures are temporary, we cannot predict the specific duration for which these precautionary measures will stay in effect and how our business may be adversely affected as a result of the pandemic’s global economic impact and associated supply chain disruptions. In the future, the pandemic may cause reduced or changed demand characteristics for our products, especially if it results in a global recession or structural shifts in the demand for our products across our end markets.

Cash, Cash Equivalents and Restricted Cash -- The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. As of December 31, 2021, and 2020, the Company held $2,125,695 and $1,515,620, respectively, of restricted cash. The restricted cash is held as security by a local financial institution for ensuring a leasing facility and for payment guarantees issued for the benefit of customers in connection with prepayments of sales orders and for warranties after the delivery of sales orders.

Accounts held in each U.S. institution are insured by the Federal Deposit Insurance Company (“FDIC”) up to $250,000. At December 31, 2021 and December 31, 2020 the Company had $11,346,826 and $0 in excess of the FDIC insured limit, respectively.

Accounts Receivable -- Accounts receivable consist of trade receivables arising in the normal course of business. The Company establishes an allowance for doubtful accounts that reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on known troubled accounts, historical experience, age, financial information that is publicly accessible and other currently available evidence. 

The roll-forward of the allowance for doubtful accounts as of December 31, 2021 and December 31, 2020 is as follows: 

Inventory – Inventory directly purchased is carried at the lower of cost or net realizable value, as determined on the first-in, first-out method.

For inventory produced, standard costs that approximate actual cost on the FIFO method are used to value inventory. Standard costs are reviewed at least annually by management, or more often in the event that circumstances indicate a change in cost has occurred.

Work in process and finished goods include material, labor, and production overhead costs. The Company adjusts the value of its inventory to the extent management determines that the cost cannot be recovered due to obsolescence or other factors.

Inventory valuation adjustments for excess and obsolete inventory are calculated based on current inventory levels, movement, expected useful lives, and estimated future demand of the products and spare parts.

Contracts Assets – Contract assets are the Company’s rights to consideration in exchange for goods or services and are recognized when a performance obligation has been satisfied but has not yet been billed. When the Company issues invoices to the customer, and the billing is higher than the capitalized Contract assets, the net amount is transferred to Contract liabilities. Contract assets/liabilities are transferred to revenue and cost of goods sold when the right to consideration is unconditional and billed per the terms of the contractual agreement.

Contract assets also include unbilled receivables, which usually comprise the last invoice remaining after the delivery of the water treatment unit, where revenue is recognized at the transfer of control based upon signed acceptance of the water treatment unit by the customer. Most commonly this invoice is sent to the customer at commissioning of the product or no later than 12 months after the delivery. Further included in Contract Assets are short-term receivables such as VAT and other receivables.

Leases -- The Company has elected to not recognize lease assets and liabilities with an initial term of 12 months or less and to not separate lease and non-lease components. The Company’s accounting for finance leases (formerly called capital lease obligations) remains substantially unchanged. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value. The Company will use the implicit rate when readily determinable. The operating lease ROU asset also included prepaid lease payments and reduced by accrued lease payments. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that those options will be exercised. Operating lease cost for lease payments will be recognized on a straight-line basis over the lease term.

Property and Equipment -- Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized upon being placed in service. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed for financial statement purposes on a straight-line basis over the estimated useful lives of the assets, which range from three to ten years.

Goodwill and Intangible Assets -- The purchase price of an acquired company is allocated between intangible assets and the net tangible assets of the acquired business, with the residual purchase price recorded as goodwill. The determination of the value of the intangible assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital.

Acquired intangible assets with determinable useful lives are amortized on a straight-line or accelerated basis over the estimated periods benefited, ranging from one to ten years. Customer relationships and other non-contractual intangible assets with determinable lives are amortized over periods of five years.

The Company evaluates the recoverability of long-lived assets by comparing the carrying amount of an asset to estimated future net undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets. The evaluation of recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of the related asset. A shortfall in these estimated operating cash flows could result in an impairment charge in the future.

Goodwill is not amortized but is evaluated annually for impairment at the reporting unit level or when indicators of a potential impairment are present. The Company estimates the fair value of the reporting unit using the discounted cash flow and market approaches. Forecasts of future cash flows are based on the Company’s best estimate of future net sales and operating expenses, using primarily expected category expansion, pricing, market segment fundamentals, and general economic conditions.

Revenue Recognition -- On January 1, 2018, the Company adopted Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers,” which includes clarifying ASUs issued in 2015, 2016 and 2017 (“new revenue standard”). The new revenue standard was applied to all open revenue contracts using the modified retrospective method as of January 1, 2018.

The Company sells products throughout the world; sales by geographical region are as follows for the year ended December 31, 2021 and 2020:

The Company’s sales by product line are as follows for the years ended December 31, 2021 and 2020:
