In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. The consolidated financial statements as of and for the year ended December 31, 2022, were audited by another auditor. Their auditor’s report, dated May 12, 2023, contained an unqualified opinion on those financial statements. B asis 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 audit. 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 audit 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 audit, 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 audit 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 audit 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 audit provides a reasonable basis for our opinion. C ritical 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) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. 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 audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. V aluation of Profit Share Liability D escription of the Matter As of December 31, 2023, the Company recorded a profit share liability of $13.8 million. As discussed in Note 7 to the financial statements, the Company entered into a profit participation preference (the “profit share liability”) with AC Midwest Energy LLC as part of its Unsecured Note Financing Agreement. The Company calculates the fair value of the profit share liability on a quarterly basis utilizing management estimates. The fair value of the profit share liability is calculated using a discounted cash flow model based on estimated future cash payments. The fair value of the profit share liability is determined on a Level 3 measurement. Inherent in the valuation of Level 3 financial instruments are certain significant judgments and estimates related to forecasted cash flows. Changes in these assumptions can significantly impact the valuation of the profit share liability and the gain or loss on change in fair value that is recorded. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management’s forecasted cash flows. H ow We Addressed the Critical Audit Matter in Our Audit To test the profit share liability calculation as of December 31, 2023, we performed the following procedures among others, by which we: · Obtained an understanding of the Company’s internal controls and the process to determine the fair value of the profit share liability. · Obtained and reviewed the Unsecured Note Agreement and evaluated management’s assessment of the terms of the agreement. · Evaluated the reasonableness of management’s cash flow forecast by comparing the forecast to historical data and trends and current events influencing expected future cash flows, including the timing of expected cash flows. · Utilized our internal valuation specialist to assist in the assessment of the appropriateness of the valuation methodology and the reasonableness of the discount rate applied, including consideration of conditions affecting market rates. · Performed sensitivity analyses to evaluate the potential impact of fluctuations in the underlying assumptions of the fair value of the profit share liability. · Tested the clerical accuracy of the profit share liability calculation. /s/ Rosenberg Rich Baker Berman, P.A.

F-7 Table of Contents MIDWEST ENERGY EMISSIONS CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2023 Note 1 - Organization Midwest Energy Emissions Corp. Midwest Energy Emissions Corp. is organized under the laws of the State of Delaware. MES, Inc. MES, Inc. is incorporated in the State of North Dakota. MES, Inc. is a wholly owned subsidiary of Midwest Energy Emissions Corp. and is engaged in the business of developing and commercializing state of the art control technologies relating to the capture and control of mercury emissions from coal fired boilers in the United States and Canada. ME2C Sponsor LLC and ME2C Acquisition Corp. ME2C Sponsor LLC is a limited liability company formed in the State of Delaware and is a wholly owned subsidiary of Midwest Energy Emissions Corp. and owns 85 % of ME2C Acquisition Corp. A decision was made in January 2023 to liquidate these entities. As such, as of December 31, 2022, the Company wrote off the assets for these entities and recorded a $ 95,500 loss. Note 2 - Liquidity and Financial Condition Under ASC 205-40, Presentation of Financial Statements—Going Concern , the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. As required by ASC 205-40, this evaluation shall initially not take into consideration the potential mitigating effects of plans that have not been fully implemented as of the date the financial statements are issued. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which contemplate continuation of the Company as a going concern and realization of assets and satisfaction of liabilities in the normal course of business and do not include any adjustments that might result from the outcome of any uncertainties related to our going concern assessment. As reflected in the consolidated financial statements, the Company had approximately $ 21 million in cash at December 31, 2023. In addition, the Company had cash provided by operating activities of $ 19 million for the year ended December 31, 2023, had working capital of $ 22 million and an accumulated deficit of $ 63 million at December 31, 2023. The accompanying consolidated financial statements as of December 31, 2023 have been prepared assuming the Company will continue as a going concern. On October 28, 2022, the Company’s principal lender agreed to extend the maturity date of all of its existing secured and unsecured debt in the principal amount of $ 13.4 million from October 31, 2022 to August 25, 2025 (see Note 7 - Related Party ). As a result, such liabilities have been classified as long-term liabilities in the accompanying consolidated financial statements as of December 31, 2023. Based upon such extension of the maturity date of such secured and unsecured debt, the Company’s current cash position and revenues from operations, management believes substantial doubt regarding the Company’s ability to continue as a going concern has been mitigated. The Company believes it will have sufficient working capital to fund operations for at least the next twelve months from the date of issuance of these financial statements. Note 3 - Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations promulgated by the United States Securities and Exchange Commission (“SEC”). F-8 Table of Contents Principles of Consolidation The consolidated financial statements include the accounts of Midwest Energy Emissions Corp. and its wholly-owned subsidiaries, MES, Inc. and ME2C Sponsor LLC, and ME2C Acquisition Corp. which is 85% owned by ME2C Sponsor LLC (collectively, the “Company”). Intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, valuation of equity issuances and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company uses estimates in accounting for, among other items, profit share liability, revenue recognition, allowance for doubtful accounts, stock-based compensation, income tax provisions, excess and obsolete inventory reserve and impairment of intellectual property. Actual results could differ from those estimates. Property and Equipment Property and equipment are stated at cost. When retired or otherwise disposed, the related carrying value and accumulated depreciation are removed from the respective accounts and the net difference less any amount realized from disposition, is reflected in earnings. For consolidated financial statement purposes, equipment is recorded at cost and depreciated using the straight-line method over their estimated useful lives of 2 to 5 years. Leasehold improvements are recorded at cost and depreciated using the straight-line method over the life of the lease. Expenditures for repairs and maintenance which do not materially extend the useful lives of property and equipment are charged to operations. Management reviews the carrying value of our property and equipment for impairment on an annual basis. Intellectual Property Intellectual property is recorded at cost and amortized over its estimated useful life of 15 years. Management reviews intellectual property for impairment when events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset or asset group is less than the carrying amount of the asset or asset group, an impairment loss equal to the excess of the asset or asset group’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated. Recoverability of Long-Lived and Intangible Assets Long-lived assets and certain identifiable intangibles held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Events relating to recoverability may include significant unfavorable changes in business conditions, recurring losses or a forecasted inability to achieve break-even operating results over an extended period. The Company evaluates the recoverability of long-lived assets based upon forecasted undiscounted cash flows. Should impairment in value be indicated, the carrying value of the long-lived and/or intangible assets would be adjusted, based on estimates of future undiscounted cash flows. The Company has evaluated the recoverability of the carrying value of the Company’s property and equipment, right of use asset and intellectual property. After completing the assessment of property and equipment for impairment as of December 31, 2023, the Company recorded an impairment expense related to property and equipment of $ 219,707 which is included in Impairment loss in the Company’s consolidated statements of operations and comprehensive income (loss). The expense was primarily related to the impairment of construction in process costs where management determined that the undiscounted future cash flows were not sufficient to recover the carrying value of these assets over the estimated useful life. No impairment charges were recognized for the year ended December 31, 2022. F-9 Table of Contents Stock-Based Compensation We account for stock-based compensation awards in accordance with the provisions of ASC 718, Compensation-Stock Compensation, which requires equity-based compensation, be reflected in the consolidated financial statements over the period of service which is typically the vesting period based on the estimated fair value of the awards. Fair Value of Financial Instruments The fair value hierarchy has three levels based on the inputs used to determine fair value, which are as follows: ☐ Level 1 — Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date. ☐ Level 2 — Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. ☐ Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The fair value hierarchy requires the use of observable market data when available. In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. Profit share liability was the only item measured at fair value on a recurring basis by the Company at December 31, 2023 and December 31, 2022. Profit share liability is considered to be Level 3. Financial instruments include cash, accounts receivable, accounts payable, and short-term debt. The carrying amounts of these financial instruments approximated fair value at December 31, 2023 and December 31, 2022 due to their short-term maturities. The fair value of the notes payable at December 31, 2023 and December 31, 2022 approximated the carrying amount as the notes were recently issued at interest rates prevailing in the market and interest rates as of December 31, 2023 and December 31, 2022. The fair value of the notes payable was determined on a Level 2 measurement. Discounts on issued debt, as well as debt issuance costs, are amortized over the term of the individual notes. The fair value of the profit share liability at December 31, 2023 and December 31, 2022 was calculated using a discounted cash flow model based on estimated future cash payments. The fair value of the profit share liability was determined on a Level 3 measurement. These values are determined using pricing models for which the assumptions utilized management’s estimates. The following tables present the Company’s liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. Fair Value Measurement as of December 31, 2023 Total Level 1 Level 2 Level 3 Liabilities: Profit share liability – related party (1) $ 14,847,937 $ - $ - $ 14,847,937 Total Liabilities $ 14,847,937 $ - $ - $ 14,847,937 Fair Value Measurement as of December 31, 2022 Total Level 1 Level 2 Level 3 Liabilities: Profit share liability – related party (1) $ 3,638,260 $ - $ - $ 3,638,260 Total Liabilities $ 3,638,260 $ - $ - $ 3,638,260 (1) See Note 7 - Related Party F-10 Table of Contents Revenue Recognition The Company records revenue in accordance with ASC 606, Revenue from Contracts with Customers . The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised 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 that core principle, an entity should apply the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation. Revenue is recognized when the Company satisfies its performance obligation under the contract by transferring the promised product to its customer that obtains control of the product. A performance obligation is a promise in a contract to transfer a distinct product to a customer. Most of the Company’s contracts have a single performance obligation, as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. As such, revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales and other taxes are excluded from revenues. Invoiced shipping and handling costs are included in revenue. Disaggregation of Revenue The Company generated revenue for the years ended December 31, 2023 and 2022 by (i) delivering product to its commercial customers, (ii) completing and commissioning equipment projects at commercial customer sites and (iii) performing demonstrations of its technology at customers with the intent of entering into long term supply agreements based on the performance of the Company’s products during the demonstrations and (iv) licensing its technology to customers. Revenue for product sales is recognized at the point of time in which the customer obtains control of the product, at the time title passes to the customer upon shipment or delivery of the product based on the applicable shipping terms. Revenue for equipment sales is recognized upon commissioning and customer acceptance of the installed equipment per the terms of the purchase contract. Revenue for demonstrations and consulting services is recognized when performance obligations contained in the contract have been completed, typically the completion of necessary field work and the delivery of any required analysis per the terms of the agreement. The following table presents sales by operating segment disaggregated based on the type of product for the years ended December 31, 2023 and 2022. All sales were in the United States. December 31, 2023 December 31, 2022 Product revenue $ 17,092,996 $ 20,644,438 License revenue 702,500 650,938 Demonstrations & Consulting revenue 90,000 108,000 Equipment revenue 54,874 216,777 $ 17,940,370 $ 21,620,153 F-11 Table of Contents Accounts receivable and allowance for credit losses Accounts receivable are presented net of an allowance for credit losses. The Company maintains allowances for credit losses. The Company reviews the accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, a customer’s payment history, its current credit-worthiness and current economic trends. Accounts are written off after exhaustive efforts at collection. Management believed that the accounts receivable were fully collectable and no allowance for credit losses was deemed to be required on its accounts receivable at December 31, 2023. The Company historically has not experienced significant uncollectible accounts receivable. As of December 31, 2023 and December 31, 2022, the Company’s allowance for doubtful accounts was $ 0 . Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, Income Taxes . Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years 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 income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 31, 2023 and 2022. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is no longer subject to tax examinations by tax authorities for the years prior to 2019. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions, and compliance with federal, state, and city tax laws. Management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Basic and Diluted Income (Loss) Per Common Share Income per share – basic is calculated by dividing net income by the weighted average number of shares of stock outstanding during the year, including shares issuable without additional consideration. Income per share – assuming dilution is calculated by dividing net income by the weighted average number of shares outstanding during the year adjusted for the effect of dilutive potential shares from options and warrants calculated using the treasury stock method and the if-converted method for preferred stock. There are 3,280,702 dilutive stock options and no dilutive warrants for the year ended December 31, 2023 as the Company reported net income for the period. There were no dilutive potential common shares for year ended December 31, 2022, because the Company incurred a net loss and basic and diluted losses per common share are the same. F-12 Table of Contents We calculate basic earnings per share by dividing net income by the weighted-average number of $5,904,013 common shares outstanding during the reporting period. Diluted earnings per share reflects the effects of potentially dilutive securities. The summary of the basic and diluted earnings per share calculations for the years ended December 31, 2023 and 2022: 2023 2022 Basic: Net Income (Loss) $ 5,904,013 $ ( 1,581,476 ) Weighted-average shares outstanding 94,171,695 90,025,209 Basic $ 0.06 ( 0.02 ) 2023 2022 Diluted: Net Income (Loss) $ 5,904,013 $ ( 1,581,476 ) Weighted-average shares outstanding 94,171,695 90,025,209 Effect of diluted securities – stock options 3,280,702 - Weighted-average shares used in the calculation of diluted earnings per share 97,452,397 90,025,209 Diluted earnings (loss) per share $ 0.06 $ ( 0.02 ) Total common stock equivalents excluded from dilutive loss per share are as follows: December 31, December 31, 2023 2022 Stock Options 9,650,000 18,876,912 Warrants 2,550,000 3,285,000 Total common stock equivalents excluded from dilutive loss per share 12,200,000 22,161,912 Concentration of Credit Risk Financial instruments that subject the Company to credit risk consist of cash and equivalents on deposit with financial institutions and accounts receivable. The Company’s cash as of December 31, 2023 and 2022 is maintained at high-quality financial institutions and has not incurred any losses to date. Customer and Supplier Concentration For the year ended December 31, 2023, three customers represented 28 %, 23 %, and 11 % of the Company’s revenues, and for the year ended December 31, 2022, four customers represented 21 %, 16 %, 13 % and 11 % of the Company’s revenues. At December 31, 2023, four customers represented 43 %, 13 %, 11 % and 10 % of the Company’s accounts receivable, and at December 31, 2022, four customers represented 24 %, 18 %, 16 % and 10 % of the Company’s accounts receivable. For the year ended December 31, 2023, 91 % of the Company’s purchases related to three suppliers. For the year ended December 31, 2022, 84 % of the Company’s purchases related to three suppliers. At December 31, 2023 and 2022, 68 % and 81 % of the Company’s accounts payable and accrued expenses related to two vendors, respectively. The Company believes there are numerous other suppliers that could be substituted should a supplier become unavailable or non-competitive. Contingencies Certain conditions may exist which may result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur. The Company’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company, or unasserted claims that may result in such proceedings, the Company’s legal counsel evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein. F-13 Table of Contents If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, the estimated liability would be accrued in the Company’s consolidated financial statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed. Loss contingencies considered remote are generally not disclosed unless they arise from guarantees, in which case the guarantees would be disclosed. Recently Issued Accounting Standards Issued in June 2021, FASB Accounting Standards Update (ASU) No. 2016-13, Measurement of Credit Losses on Financial Instruments adds to U.S. GAAP an impairment model known as the current expected credit loss (CECL) model, which is based on expected losses rather than incurred losses. This guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early application of the amendments is permitted. Effective January 1, 2023, the Company adopted ASU No. 2016-13. The adoption of ASU No. 2016-13 did not have a material effect on the accompanying consolidated financial statements.

This discount was based on an applicable market rate for unsecured debt for the Company of 21 % and is being amortized as interest expense over the life of the loan. In accordance with the Unsecured Note Financing Agreement, AC Midwest shall be entitled to a profit participation preference equal to 1.0 times the original principal amount (the “Profit Share”). The Profit Share is “non-recourse” and shall only be derived from and computed on the basis of, and paid from, Net Litigation Proceeds from claims relating to the Company’s intellectual property, Net Revenue Share and Adjusted Free Cash Flow (as such terms are defined in the Unsecured Note Financing Agreement), and Equity Offering Net Proceeds as described below. On August 30, 2022, AC Midwest agreed to an extension of the maturity date of the AC Midwest Unsecured Note (and AC Midwest Secured Note) from August 25, 2022 to September 30, 2022. Such extension was expected to provide the Company sufficient time in which to conclude the process of negotiating certain changes and modifications to such financing arrangements. On September 28, 2022, AC Midwest agreed to an additional short-term extension of such maturity date from September 30, 2022 to October 31, 2022.

Any remaining principal balance due on the Unsecured Note shall be due and payable in full on the maturity date. The Profit Share, however, if not paid in full on or before the maturity date, shall remain subject to Unsecured Note Financing Agreement until full and final payment. The Company is utilizing the methodology behind the ASC 815, Derivatives and Hedging and ASC 480, Distinguishing Liabilities from Equity to determine how to account for the profit-sharing portion of the note payable. Although the transaction is not indexed to MEEC’s common stock the profit sharing has the characteristics of a freestanding financial instrument because the profit sharing is not callable by the lender, it will be paid out past the maturity of the Unsecured Note Payable and, the fair value will fluctuate over time based on payment predictions. The Profit Share was determined to have a fair value of $ 1,954,383 upon grant. The discounted cash flow model assumptions used at December 31, 2023 to calculate the Profit Share liability included: the projected full repayment of the profit share liability of $ 17,654,931 upon the receipt of Net Litigation Proceeds in 2025, and an annual market interest rate of 14.55 %. The profit share liability will be marked to market every quarter utilizing management’s estimates.

Legal proceedings On July 17, 2019, the Company initiated patent litigation against certain defendants in the U.S. District Court for the District of Delaware for infringement of certain United States patents owned by the Company . These patents relate to the Company’s two-part Sorbent Enhancement Additive (SEA ® ) process for mercury removal from coal-fired power plants. Named as defendants in the lawsuit were (i) Vistra Energy Corp., AEP Generation Resources Inc., NRG Energy, Inc., Talen Energy Corporation, and certain of their respective affiliated entities, all of which are owners and/or operators of coal-fired power plants in the United States, and (ii) Arthur J. Gallagher & Co., DTE REF Holdings, LLC, CERT Coal Holdings LLC, Chem-Mod LLC, and certain of their respective affiliated entities, and additional named and unnamed defendants, all of which operate or are involved in operations of coal facilities in the United States. In the lawsuit, the Company alleges that each of the defendants has willfully infringed certain of the Company’s patents and seeks unspecified damages, attorneys’ fees, costs and injunctive relief. F-19 Table of Contents During 2020, each of the four major utility defendants in the above action filed petitions for Inter Partes Review with the United States Patent and Trademark Office, seeking to invalidate certain claims to the patents which are subject to the litigation. Between July 2020 and January 2021, we entered into agreements with each of the four major utility defendants in such action which included certain monetary arrangements and pursuant to which we have dismissed all claims brought against each of them and their affiliates, and such parties have withdrawn from petitions for Inter Partes Review with the United States Patent and Trademark Office. Such agreements entered into with such parties provide each of them and their affiliates with a non-exclusive license to certain Company patents (related to the Company’s two-part Sorbent Enhancement Additive (SEA®) process) for use in connection with such parties’ coal-fired power plants. Subsequently, and as a result of certain rulings by the Court, certain defendants were dismissed in the action, certain defendants were added and certain originally named defendants remained in the action. A jury trial was scheduled for November 13, 2023. On November 9, 2023, the Company entered into a confidential binding term sheet with Arthur J. Gallagher & Co., and various of its affiliated entities (collectively “AJG”), and DTE Energy Resources LLC and various of its affiliated entities (collectively “DTE”), to resolve the patent litigation. Pursuant to the term sheet, all claims and counterclaims asserted by the parties in such patent litigation have been dismissed with prejudice, although such term sheet does not affect any other claim brought against the remaining CERT defendants. The financial aspects of the term sheet remain confidential pursuant to its terms. In addition, effective November 9, 2023, Alistar Enterprises, LLC (“Alistar”), one of the remaining CERT defendants, entered into a settlement agreement with the Company which provided that all claims and counterclaims asserted in the action between the Company and Alistar be dismissed with prejudice.

Stock options exercised during the year ended December 31, 2023 include 850,000 that were exercised for cash and 875,839 which were a cashless exercise. Note 11 - Warrants The Company utilized a Black-Scholes options pricing model to value warrants at the issuance date. This model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until the warrants are exercised. When calculating the value of warrants issued, the Company uses a volatility factor, a risk-free interest rate and the life of the warrant for the exercise period. No warrants were issued or exercised during the years ended December 31, 2023 and 2022.

Significant components of the Company’s deferred tax assets and liabilities are as follows at December 31: 2023 2022 Deferred tax assets: Net operating loss carryforwards $ 2,751,000 $ 6,495,000 Stock based compensation 1,517,000 2,008,000 Other 186,000 23,000 Total deferred tax assets 4,454,000 8,526,000 Deferred tax liabilities: Property and equipment - ( 1,000 ) Intangible assets - ( 98,000 ) Total deferred tax liabilities - ( 99,000 ) Valuation Allowance ( 4,454,000 ) ( 8,427,000 ) Net deferred tax asset $ - $ - As of December 31, 2023, the Company has U.S. federal net operating loss carryovers (“NOLs”) of approximately $ 12,917,000 available to offset taxable net income in a given year of which $ 5,920,000 expires from 2034 through 2037 and $ 6,997,000 does not expire. The Company also has state NOL carryforwards of approximately $ 815,000 which start to expire in 2025 . If not used, these NOLs may be subject to limitation under Internal Revenue Code Section 382 should there be a greater than 50% ownership change as determined under the regulations. The Company plans on undertaking a detailed analysis of any historical and/or current Section 382 ownership changes that may limit the utilization of the net operating loss carryovers. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon future generation for taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all the information available, Management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the years ended December 31, 2023 and 2022, the valuation allowance decreased by $ 3,973,000 and $ 188,000 , respectively. The Company evaluated the provisions of ASC 740-10 related to the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740-10 prescribes a comprehensive model for how a company should recognize, present, and disclose uncertain positions that the Company has taken or expects to take in its tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. Differences between tax positions taken or expected to be taken in a tax return and the net benefit recognized and measured pursuant to the interpretation are referred to as “unrecognized benefits.” A liability is recognized (or amount of net operating loss carry forward or amount of tax refundable is reduced) for unrecognized tax benefit because it represents an enterprise’s potential future obligation to the taxing authority for a tax position that was not recognized as a result of applying the provisions of ASC 740-10. There were no unrecognized tax benefits as of December 31, 2023. The Company is no longer subject to tax examinations by tax authorities for years prior to 2019. If applicable, interest costs related to the unrecognized tax benefits are required to be calculated and would be classified as “Other expenses – Interest” in the statement of operations. Penalties would be recognized as a component of “General and administrative.” No interest or penalties on unpaid tax were recorded during the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, no liability for unrecognized tax benefits was required to be reported. The Company does not expect any significant changes in its unrecognized tax benefits in the next year. F-26 Table of Contents Note 13 - Subsequent Events AC Midwest On February 27, 2024, the Company entered into an Unsecured Debt Restructuring Agreement (the “Debt Restructuring Agreement”) with AC Midwest which replaced and superseded the Unsecured Note Financing Agreement. See Note 7 – Related Party. Pursuant to the Debt Restructuring Agreement, on February 27, 2024, the Company (i) paid AC Midwest $ 9,040,000 as a reduction in the outstanding principal balance of the Unsecured Note, (ii) issued to AC Midwest a new unsecured replacement note representing the remaining outstanding principal balance of the Unsecured Note in the principal amount of $ 4,114,931 (the “New Note”), and (iii) paid AC Midwest $275,625 representing the remaining principal balance under the Secured Note of $ 271,686 plus interest of $ 3,939 . In addition, within 30 days, the Company would either facilitate the private sale to third parties of certain shares of common stock of the Company held by AC Midwest for a purchase price of no less than $960,000, which amount shall be applied as a credit against the principal balance due on the New Note dollar for dollar, or pay AC Midwest $960,000 toward the principal balance due on the New Note . The private sale of shares for the purchase price of $ 960,000 was completed on March 11, 2024. Any remaining principal balance on the New Note shall be due August 27, 2024 (the “Maturity Date”), which is six months from February 27, 2024. Until repaid in full, the New Note shall accrue interest at a rate equal to SOFR plus 2.0 % per annum. The New Note completely replaces and supersedes the Unsecured Note, which shall be of no further force and effect. In addition, pursuant to the Debt Restructuring Agreement, AC Midwest shall be entitled to a profit participation preference equal to $ 7,900,000 (the “Restructured Profit Share”). The Restructured Profit Share is “non-recourse” and shall only be paid from Net Litigation Proceeds (as defined in the Debt Restructuring Agreement) from claims relating to our intellectual property. Following the receipt of any Net Litigation Proceeds, we shall prepay any remaining principal balance of the New Note and pay the Restructured Profit Share in an amount equal to 75.0% of such Net Litigation Proceeds until the New Note and Restructured Profit Share have been paid in full . The Restructured Profit Share completely replaces and supersedes the terms and conditions of the Profit Share in the amount of $ 17,654,931 provided for in the Unsecured Note Financing Agreement, which shall be of no further force and effect. The Restructured Profit Share, if not paid in full on or before the Maturity Date, shall remain subject to the terms of the Debt Restructuring Agreement. In addition to facilitating the private sale to third parties as described above, AC Midwest has granted the Company the exclusive right until December 31, 2024 to facilitate the sale of all or a portion of the remaining balance of the shares of common stock of the Company held by AC Midwest, which proceeds above a certain amount will be applied as a credit against the Restructured Profit Share dollar for dollar.
