Basis of Presentation

The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as codified in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”).

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and its majority-owned subsidiary. All material intercompany transactions and accounts have been eliminated in the consolidation.

**Use of Estimates **

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and judgments include revenue recognition, allowance for estimated credit losses, reserves for excess and obsolete inventories, impairment evaluations of long-lived assets and goodwill, fair value measurements of warrants and stock-based compensation, and assessments of contingent liabilities.

Foreign Currency

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”); and the functional currency of LiqTech JiTRI is the Renminbi (“RMB”). 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, equity is translated at historical cost, and all revenue and expenses are translated into U.S. Dollars at the average exchange rates prevailing during thetwelve months ended* December 31, 2025,and2024*. 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.

31

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid debt instruments purchased with a maturity ofthree months or less to be cash equivalents. As of* December 31, 2025*, and2024, the Company held $0 and $0, 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, 2025,and December 31, 2024*, the Company had $0 and $4,414,510 in excess of the FDIC insured limit, respectively.

Accounts Receivable and Current Expected Credit Losses

Accounts receivable consist of trade receivables arising from credit sales to customers in the normal course of business. These receivables are recorded at the time of sale, net of an allowance for current expected credit losses. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic326, “Financial Instruments–* Credit Losses*,” the Company estimates expected credit losses based on historical bad debt experience, the aging of accounts receivable, the current creditworthiness of customers, prevailing economic conditions, and reasonable and supportable forward-looking information. Accounts receivable balances are written off when they are determined to be uncollectible.

The roll-forward of the allowance for current expected credit losses for the year ended* December 31, 2025,and December 31, 2024* were as follows:

Inventories

Inventories directly purchased are carried at the lower of cost or net realizable value, as determined on thefirst-in,first-out (“FIFO”) method. For inventories produced, standard costs that approximate actual cost on the FIFO method are used to value inventories. Standard costs are reviewed at least annually by management or more often if 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 inventories to the extent management determines that the cost cannot be recovered due to obsolescence or other factors. Inventory valuation adjustments for excess and obsolete inventories are calculated based on current inventories levels, movement, expected useful lives, and estimated future demand for our products.

Leases

The Company has elected tonot recognize lease assets and liabilities with an initial term of12 months or less, are Insignificant in value, and tonot separate lease and non-lease components. The Company’s accounting for finance leases 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 donot 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 uses the implicit rate when determinable. The operating lease ROU asset also included prepaid lease payments, reduced by accrued lease payments. The Company’s lease terms* may*include options to extend or terminate the lease, recognized 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 toten years.

Long-Lived Assets

The Company assesses 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 the Company considers 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 its use of the assets. The Company measures the recoverability of assets that will continue to be used in its operations by comparing the carrying value of the asset grouping to its estimate of the related total future undiscounted net cash flows. If an asset grouping’s carrying value isnot 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.

32

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

Management has analyzed the impact of the current economic climate on its financial statements as of* December 31, 2025*, and has determined that the changes to its significant judgements and estimates didnot have a material impact with respect to goodwill, intangible assets, or long-lived assets. During the years ended* December 31, 2025,and2024*, no impairment charge of long-lived assets has been recorded.

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 arenot 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 fromone toten years. Customer relationships and other non-contractual intangible assets with determinable lives are amortized over periods offive 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, butnot 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 isnot 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. During the years ended* December 31, 2025,and2024*, no impairment charge for goodwill was recorded.

Revenue Recognition

The Company records revenue in accordance with FASB ASC Topic606, “ Revenue from Contracts with Customers.” Revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the followingfive-step approach: (1) identify the contract with the customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to performance obligations in the contract; and (5) recognize revenue when or as a performance obligation is satisfied.

The Company sells products throughout the world. Sales by geographical region for the years ended* December 31, 2025,and2024* were as follows:

The Company’s sales by product line for the years ended* December 31, 2025,and2024* were as follows:

33

For Systems and Aftermarket, Filters and Membranes, and Components, revenue is recognized when performance obligations specified within 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 along with 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 to receive 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 isnot significant. Pre-payments received prior to satisfaction of performance obligations are recorded as a contract liability. Considering the relatively short time between revenue recognition and receipt of payment, financing components donot 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 to the customer based upon sales and delivery conditions specified in the sales contract, or for larger projects in line with completion. This typically occurs upon shipment of the system from the production facility but can also occur upon other agreed delivery terms. In connection with the completion of the system, it is normal procedure to issue a FAT (Factory Acceptance Test) asserting 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 asecond performance obligation and is valued at cost, with the addition of a standard gross profit. Thissecond performance obligation is recognized as revenue at the time of the commissioning services being rendered 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., thefirst performance obligation), this portion is recognized as contract liabilities.

Aftermarket sales represent spare 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.

Contracts Assets and Contract Liabilities* *

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 hasnot 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 revenues 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 System unit, where revenue is recognized at the transfer of control based upon signed acceptance of the unit by the customer. Most commonly, this invoice is sent to the customer at commissioning of the product orno later than12 months after delivery. Further included in Contract Assets are short-term receivables such as VAT and other receivables.

The roll-forward of contract assets and contract liabilities for the years ended* December 31, 2025,and2024* were as follows:

34

Cost of Sales

The Company includes product costs (i.e., material, direct labor and overhead costs), shipping and handling expense, production-related depreciation expense, and product license agreement expense in cost of sales.

Advertising Costs

Costs incurred in connection with advertising of the Company’s products are expensed as incurred. Advertising costs are included in selling expenses, and total advertising costs amounted to $105,847 and $56,037 for the years ended* December 31, 2025,and2024*, respectively.

Research and Development Cost

The Company expenses research and development costs for the development of new products as incurred. Included in operating expense for the years ended* December 31, 2025,and2024* were $1,163,651 and $1,352,060, respectively, of research and development costs.

Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with ASC740, “Income Taxes.” Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and establishes a valuation allowance if, based on the weight of available evidence, it believes it is more likely thannot that all or a portion of the deferred tax assets willnot be realized.

The Company recognizes the tax benefit of an uncertain tax position only if it is more likely thannot the position will be sustainable upon examination by the taxing authority, including resolution of any related appeals or litigation processes. This evaluation is based on all available evidence and assumes that the tax authorities have full knowledge of all relevant information concerning the tax position. The tax benefit recognized is measured as the largest amount that has a greater than50% likelihood of being realized upon ultimate settlement. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in income tax expense.

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 warranties, 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.

Loss Per Share

The Company calculates loss per share in accordance with FASB ASC260, "Earnings Per Share". Basic earnings per common share (EPS) are based on the weighted average number of common shares outstanding during each period. Diluted earnings per common share are based on shares outstanding (computed as under basic EPS) and potentially dilutive common shares. Potential common shares included in the diluted earnings per share calculation include in-the-money stock options and warrants that have been granted but havenot been exercised.

Stock-Based Compensation

Stock-based awards granted to qualified employees, non-employee directors, and consultants are measured at fair value and recognized as an expense in accordance with ASC Topic718, “Share-Based Payments.” For service-based awards, stock-based compensation is recognized on a straight-line basis over the requisite service period, which is generally the vesting period. The fair value of our stock options is estimated using a Black-Scholes option valuation model. Restricted stock awards are valued based on the closing stock price on the date of grant. The Company has elected to recognize forfeitures as they occur.

Warrant Liabilities

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants in accordance with ASC480, “Distinguishing Liabilities from Equity,” and ASC815-40, “Contracts in Entity’s Own Equity.” This assessment, which requires the use of professional judgment, considers whether the warrants are freestanding financial instruments pursuant to ASC480, meet the definition of a liability pursuant to ASC480, and meet all of the requirements for equity classification under ASC815-40, including whether the warrants are indexed to the Company’s own shares and whether the events where holders of the warrants could potentially require net cash settlement are within the Company’s control, among other conditions for equity classification. Warrant liabilities are recognized at fair value, with changes in fair value recognized in the consolidated statement of operations each period.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We provide credit, in the normal course of business. We perform ongoing credit evaluations of our customers and maintain allowances for potential credit losses. Due to the diversified nature and number of customers, concentrations of credit risk with respect to accounts receivable are limited.

35

Concentrations

One customer accounted for 12% of the Company’s revenue for the year ended* December 31, 2025.No customers accounted for more than10% of the revenue for the year ended December 31, 2024.*

The Company’s accounts receivable from four customers made up 58% of the total balance as of* December 31, 2025.The Company’s accounts receivable fromone customer made up 18% of the total balance as of December 31, 2024.*

No supplier accounted for more than10% of the Company’s purchases of inventory for the year ended* December 31, 2025or year ended December 31, 2024.*

Fair Value of Financial Instruments

The Company accounts for fair value measurements for financial assets and liabilities in accordance with FASB ASC Topic820**“Fair Value Measurement”. The authoritative guidance, which, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the exit price, representing the amount that would either be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes athree-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash and cash equivalents, restricted cash, accounts receivable, other receivables, prepaid expenses, accounts payable, and accrued expenses approximate their recorded values due to their short-term maturities.

Recently Adopted Accounting Pronouncements

In* August 2023,the FASB issued ASU2023*-05, “Business Combinations—Joint Venture Formations (Subtopic805-60): Recognition and Initial Measurement,” which requires a newly-formed joint venture to apply a new basis of accounting to its contributed net assets, resulting in the joint venture initially measuring its contributed net assets at fair value on the formation date. ASU2023-05 is effective for all joint venture formations with a formation date on or after* January 1, 2025,with early adoption permitted. These amendments are to be applied prospectively, with retrospective application permitted for joint ventures formed before the effective date. The adoption of ASU2023*-05 didnot have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In* December 2023,the FASB issued ASU2023*-09, “Income Taxes (Topic740): Improvements to Income Tax Disclosures,” which enhances the transparency and decision usefulness of income tax disclosures by requiring; (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU2023-09 is effective for fiscal years beginning after* December 15, 2025,*with early adoption permitted. These amendments are to be applied prospectively, with retrospective application permitted. The Company is currently evaluating the impact this standard will have on its consolidated financial statements.

In* November 2024,the FASB issued ASU2024*-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic220-40): Disaggregation of Income Statement Expenses,” which requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization included in each relevant expense caption presented on the statement of operations. The standard also requires disclosure of qualitative description of the amounts remaining in relevant expense captions that arenot separately disaggregated quantitatively, as well as the total amount of selling expenses and an entity’s definition of selling expenses. ASU2024-03 is effective for annual periods beginning after* December 15, 2026,and interim periods beginning after December 15, 2027.The Company is currently evaluating the impact this standard will have on its condensed consolidated financial statements. The Company currently believes there areno* other issued andnot yet effective accounting standards that are materially relevant to its consolidated financial statements.

In* July 2025,the FASB issued ASU2025*-05, Financial Instruments—Credit Losses (Topic326). This guidance contains amendments that provide decision-useful information to investors and other financial statement users while reducing the time and effort necessary to analyze and estimate credit losses for current accounts receivable and current contract assets. The amendments will be effective for annual reporting periods beginning after* December 15, 2025,and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements havenot* yet been issued or made available for issuance. The Company is currently evaluating the impact of ASU2025-05 on its condensed consolidated financial statements and related disclosures.

NOTE2 - GOING CONCERN

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate continuation of the Company as a going concern. The Company has incurred recent operating losses and used cash in its operations, which raises substantial doubt about its ability to continue as a going concern for thetwelve months following the issuance of these financial statements. The consolidated financial statements donot include any adjustments that might result from the outcome of this uncertainty.

Management continues to implement cost optimization and operational initiatives intended to improve liquidity and support a sustainable path toward profitability. The Company is actively evaluating financing alternatives, including potential debt or equity financing and other strategic arrangements, to strengthen its capital position. While there can beno assurance that such funding will be obtained on acceptable terms, Management’s plans are intended to improve liquidity and support the Company’s ability to continue operations; however, there can beno assurance these plans will be successful.

As of* December 31, 2025,*the Company had cash and cash equivalents of $5,070,385, net working capital of $11,237,788, an accumulated deficit of $94,795,121 and total assets and liabilities of $27,278,097 and $16,905,861, respectively.

Senior Promissory Notes

On* June 22, 2022,the Company issued and sold Senior Promissory Notes in an aggregate principal amount of $6.0 million (the “Notes”) and issued warrants to purchase 531,250 shares of Common Stock to affiliates of Bleichroeder L.P.,21 * AprilFund, L.P., and21 * April*Fund, Ltd. (together, the “Purchasers”), pursuant to a note and warrant purchase agreement entered into with the Purchasers (the “Note and Warrant Purchase Agreement”). The warrants issued in this transaction have an exercise price of $5.20 per share, a term offive years and are exercisable for cash at any time.

The Notes originally had a term of 24 months and didnot bear interest during this period. If the Notes arenot repaid on or before thesecond anniversary of issuance, however, the Notes will thereafter bear interest of 10% per annum, which would increase by 1% each month the Notes remain unpaid, up to a maximum of 16% per annum, payable monthly.
