−Removed: 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.
−Removed: The demand for our DPFs reflects a continued interest in environmental solutions to reduce global CO2 emissions amid increased political and regulatory efforts.
−Removed: Furthermore, for the years ended December 31, 2021 and 2020, LiqTech received revenue from government grant projects of $277,428 and $599,102, respectively.

+Added: The decrease in sales of systems and related services of $1,899,179, reflecting a year on year decline of 26%, was a result of the negative impact of the uncertain macroeconomic environment and prolonged inflationary pressure, but also increased supply chain restrictions and general market volatility, which has resulted in significant restrictions and business limitations including a substantial decline in the demand and delivery of water treatment systems for the global marine scrubber industry.
+Added: The demand for our ceramic membranes and DPFs reflects continued interest in advanced environmental filtration solutions with a focus on the reduction of global CO2 emissions amid increased political and regulatory efforts, resulting in a year-on-year constant currency increase of 7%, offset by the negative impact of the currency headwinds from the weakening of the EUR compared to the USD, resulting a year-on-year decline of 5% to $6,844,861.
+Added: The sale of plastic products benefitted from a year-on-year increase of 10% measured in local currency predominantly in the first half of the year underpinned by a diversified customer base, stable order intake, and delivery of large orders for the Asia Pacific marked, followed by increased uncertainty and reduced activity levels amid the European energy crisis in the second half of the year.

−Removed: Furthermore, increased cost related to the China project ramp-up and changes in sales mix negatively impacted the 2021 gross profit.
+Added: The decrease in gross profit was largely the result of lower overall market activity and a lower relative mix of filtration system sales in our product mix, which typically command higher average gross margins.
+Added: Gross profit was further negatively impacted by the European energy crisis amid the Russia and Ukraine conflict and corresponding high electricity costs that also negatively impacted our competitive positioning as compared to companies operating outside of Europe, where the energy crisis has been less pronounced.
+Added: Proactive measures such as the reduction in capacity and the implementation of electricity price surcharges were implemented by the company to defend profitability to the extent possible.
+Added: Furthermore, gross profit also included higher provisions for obsolescence and certain non-recurring costs associated with a strategic review of inventories.

+Added: The decrease is explained by the cost reduction and reorganization efforts initiated in 2022, including headcount reductions and organizational streamlining, partly offset by increased costs associated with increasing direct sales efforts, consulting service engagements, direct marketing activities, and bad debt provisions.
General and administrative expenses for the year ended December 31, 2022, were $5,701,955 compared to $5,836,629 for the same period in 2021, representing a decrease of $134,674, or 2%.

+Added: However, these savings were partly offset by non-recurring costs related to the CEO transition (increased non-cash compensation and recruitment expense) and consultancy costs associated with the now closed Chinese factory.
+Added: Included in general and administrative expenses is non-cash compensation expense of $934,423 and $481,105 for the years ended December 31, 2022 and December 31, 2021, respectively, representing an increase of $453,318, or 94%, attributable to stock grants to management in the context of the CEO transition.

−Removed: 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.

+Added: Increased costs were partly offset by the benefits from the USD appreciation against the EUR/DKK-denominated cost base, general cost reductions and reorganization activities.
Liquidity and Capital Resources
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
−Removed: 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.
+Added: Based on the continued market volatility and geopolitical unrest pertaining to the Russia and Ukraine conflict, European energy crisis, and macro-economic uncertainty, the Company is unable to predict the full impact this will have on our long-term financial condition, results of operations, liquidity, and cash flows.
+Added: The Company has planned and executed on decisive measures in 2022 to help safeguard the business and its financial position by reducing cost, headcount, and overall capex commitments, which together with the successful completion of the $26.5 million public offering of common stock and pre-funded warrants, substantially improved the near-term liquidity position of the Company.
+Added: Furthermore, in June 2022, the Company completed the refinancing of its $15 million Convertible Note due in 2023, partly funded by the issuance of the new $6 million Senior Promissory Notes due in June 2024 along with the proceeds from the public offering.
+Added: The Senior Promissory Notes are interest-free, with full redemption after 24 months.
+Added: Based on current projections, which are subject to significant uncertainties, including the duration and severity of global macroeconomic issues, commodity volatility, and continued global supply chain disruptions, the Company believes the cash on hand, as well as ongoing cash generated from operations, will be sufficient to cover its capital requirements and committed investments for the next 12 months.
+Added: Continued market uncertainty and reduced order intake caused by weakening global macroeconomic conditions, recession, or a resurgence of the COVID-19 pandemic, however, could unfavorably impact the Company’s ability to generate positive cash flow and thereby significantly reduce its profitability and liquidity position.
+Added: While the Company anticipates that its proactive measures will be sufficient to protect the business over the coming 12 months, the Company cannot predict the specific duration and severity of the unfavorable market dynamics that may adversely affect the business.
+Added: In the future, the Company may experience reduced or changed demand for its products and services, especially if there is a global recession, structural shift in regulation, or the continuation of escalating interest rates that adversely impacts the investment decisions of our customers.
+Added: The Company has historically satisfied its capital and liquidity requirements through offerings of equity instruments, cash from operations, and our available lines of credit.
+Added: On December 31, 2022, the Company had net working capital of $21,581,287, including cash of $16,597,371, and on December 31, 2021, the Company had net working capital of $11,199,258, including cash of $17,489,380.
+Added: The increase in net working capital of $10,382,029 compared to December 31, 2021 is mainly a result of the capital raise and repayment of the Convertible Note.
In connection with certain orders, we provide the customer a working guarantee, a prepayment guarantee, or a security bond.
−Removed: For that purpose, we maintain a guaranteed credit line of DKK13,000,000 (approximately $2,000,000).
−Removed: The credit line is secured by a cash deposit of $2,000,000.
+Added: For that purpose, we maintain a guaranteed credit line of EUR 1,350,000 (approximately $1,440,000), which is secured by a cash deposit.
+Added: Going Concern and Management ’
+Added: The financial statements included elsewhere herein for the year ended December 31, 2022, were prepared under the assumption that we would continue our operations as a going concern, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business.
+Added: As of December 31, 2022, we had cash and cash equivalents of $16,597,371, an accumulated deficit of $67,351,035, and total liabilities of $16,816,283.
+Added: We have incurred losses from continuing operations, have used cash in our continuing operations, and are dependent on additional financing to fund operations.
+Added: These conditions raise substantial doubt about our ability to continue as a going concern for one year after the date the financial statements are issued.
+Added: The financial statements included elsewhere herein do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.
+Added: The Company has initiated substantial cost reductions and profitability improvement measures in order to right size the business and develop a clear and sustainable path to profitability, further underpinned by an updated strategy and onboarding of key management resources.
+Added: However, there can be no assurance that the Company will be able to obtain any sources of funding.
+Added: Such additional funding may not be available or may not be available on reasonable terms, and, in the case of equity financing transactions, could result in significant additional dilution to our stockholders.
+Added: If we do not obtain required additional equity or debt funding, our cash resources will be depleted and we could be required to materially reduce or suspend operations, which would likely have a material adverse effect on our business, stock price and our relationships with third parties with whom we have business relationships, at least until additional funding is obtained.
+Added: If we do not have sufficient funds to continue operations, we could be required to seek bankruptcy protection or other alternatives that could result in our stockholders losing some or all of their investment in us.
+Added: Funding that we may receive during fiscal 2023 is expected to be used to satisfy existing and future obligations and liabilities and working capital needs, as well as future operating losses.
