Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	1. Nature of Operations Description of Business Unless the context requires otherwise in these notes to the consolidated financial statements, the terms “SHI,”, “ the “Company,” “we,” “us,” and “our” refer to Soluna Holdings, Inc. together with its consolidated subsidiaries, “SDI” refers to Soluna Digital, Inc. and previously, “SCI” refers to Soluna Computing, Inc., formerly known as EcoChain, Inc. Soluna Holdings, Inc. is a digital infrastructure company that specializes in transforming surplus renewable energy into computing resources. The Company’s strategy is to operate modular data centers co-located with wind, solar, and hydroelectric power plants, supporting compute-intensive applications, including Bitcoin mining, generative AI, and scientific computing. This approach aims to create a more sustainable grid while providing cost-effective and environmentally friendly computing solutions. Soluna Holdings, Inc., was originally incorporated in the State of New York in 1961 as Mechanical Technology, Incorporated and reincorporated in the State of Nevada on March 24, 2021. Headquartered in Albany, New York, the Company changed its name from “Mechanical Technology, Incorporated” to Soluna Holdings, Inc. on November 2, 2021. On October 29, 2021, Soluna Callisto merged into Soluna Computing, Inc. (“SCI”), a private green data center development company. Effective December 31, 2023, SCI transferred substantially all of its assets to SHI and/or its subsidiaries, and SHI currently conducts its business through its wholly owned subsidiary, Soluna Digital, Inc. (“SDI”). Additionally, SHI formed Soluna Cloud, Inc. (“Soluna Cloud”) on March 24, 2024, to operate cloud, co-location, and data hosting services related to high performance computing and AI. On April 2, 2024, SHI formed Soluna Energy, Inc. (“SEI”) to own and manage renewable energy power purchase agreements and land leases through a series of service subsidiaries. During fiscal year 2021, the Company commenced mining operations at its Murray, Kentucky location (“Project Sophie”) and Calvert City, Kentucky site (“Project Marie”). Project Marie was decommissioned in February 2023, while Project Sophie transitioned its focus from proprietary Bitcoin mining to hosting customers’ Bitcoin mining operations in the second quarter of 2023. All 25 MW of Project Sophie now perform data hosting services, including an AI customer pilot conducted during the first half of 2024. The Company has since sold all Bitcoin miners at Project Sophie and redeployed the capital. In September 2022, the Company divested specific mining assets at its Wenatchee, Washington facility (“Project Edith”), while continuing to manage operational contracts for the new owner. In August 2024, the Company divested the legal entity and ceased management of operational contracts for the new owner. The Company’s Texas site (“Project Dorothy”), located at a wind farm, holds the potential for up to 100 MW of power generation. By June 2024, SHI had energized 50 MW of the site across two phases, Project Dorothy 1A and 1B. As of September 30, 2024, SHI holds a 14.6 51 28 On June 18, 2024, Soluna AL CloudCo, LLC (“CloudCo”), a subsidiary of Soluna Cloud, entered into an agreement with Hewlett Packard Enterprise Company (“HPE”). Under this agreement, HPE will provide datacenter and cloud services for AI and supercomputing applications utilizing NVIDIA H100 Graphic Processing Units. This agreement involves an initial pre-payment of $ 10.3 34 Soluna is committed to leveraging its modular data centers and renewable energy partnerships to support the growing demands of Bitcoin mining, AI, and other high-performance computing industries, while maintaining a focus on sustainable, cost-effective energy use. Going Concern and Liquidity The Company’s condensed financial statements as of September 30, 2024 have been prepared using generally accepted accounting principles in the United States of America (“U.S. GAAP”) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As shown in the accompanying condensed financial statements, the Company was in a net loss, has negative working capital, and has significant outstanding debt as discussed in Note 7 as of September 30, 2024. In addition, Soluna MC Borrowing has a litigation matter with NYDIG ABL LLC (“NYDIG”) in relation to their Master Equipment Finance Agreement. See further discussion around the NYDIG litigation in Note 9. These factors, among others indicate that there is substantial doubt about the Company’s ability to continue as a going concern within one year after issuance of these condensed financial statements as of September 30, 2024, or November 14, 2024. The ability to continue as a going concern is dependent upon the Company generating profitable operations in the future and/or obtaining the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. In the near term, management is evaluating and implementing different strategies to obtain financing to fund the Company’s expenses and growth to achieve a level of revenue adequate to support the Company’s current cost structure. Financing strategies may include, but are not limited to, stock issuances, project level equity, debt borrowings, partnerships and/or collaborations. If the Company is unable to meet its financial obligations, it could be forced to restructure or refinance, seek additional equity capital or sell its assets. The Company might then be unable to obtain such financing or capital or sell its assets on satisfactory terms. There can be no assurance that additional financing will be available to the Company when needed or, if available, that it can be obtained on commercially reasonable terms. If the Company is not able to obtain the additional financing on a timely basis, if and when it is needed, it will be forced to delay or scale down some or all of its development activities or perhaps even cease the operation of its business. In addition to the Company’s cash on hand for available use of approximately $ 8.8 25 The Company in fiscal year 2024 will continue to look to evaluate different strategies to obtain financing to fund operations. However, management cannot provide any assurances that the Company will be successful in accomplishing additional financing or any of its other plans. These financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.	1. Nature of Operations Description of Business Unless the context requires otherwise in these notes to the consolidated financial statements, the terms “SHI,” the “Company,” “we,” “us,” and “our” refer to Soluna Holdings, Inc. together with its consolidated subsidiaries, “SCI” refers to Soluna Computing, Inc, formerly known as EcoChain, Inc., and “MTI Instruments” refers to MTI Instruments, Inc.. Soluna Holdings, Inc., formerly known as Mechanical Technology, Incorporated was incorporated in Nevada on March 24, 2021, and is the successor to Mechanical Technology, Inc., which was incorporated in the State of New York in 1961, as a result of a merger which became effective on March 29, 2021, and is headquartered in Albany, New York. Effective November 2, 2021, the Company changed its name from “Mechanical Technology, Incorporated” to “Soluna Holdings, Inc.” The Company is a digital infrastructure company specializing in transforming surplus renewable energy into computing resources. Our modular data centers can co-locate with wind, solar, or hydroelectric power plants and support compute intensive applications including Bitcoin Mining, Generative AI, and Scientific Computing. This pioneering approach to data centers helps energize a greener grid while delivering cost-effective and sustainable computing solutions. SHI conducted its business through its wholly-owned subsidiary, Soluna Computing, Inc. (“SCI”). The Company formed a wholly owned subsidiary of SHI on December 31, 2023, Soluna Digital, Inc. (“Soluna Digital”, or “SDI”). Effective December 31, 2023, SCI transferred substantially all of its assets to SHI or its subsidiaries, including SDI. In fiscal year 2021, SCI began mining operations in Murray, Kentucky, (“Project Sophie”) and Calvert City, Kentucky, (“Project Marie”). Project Marie had performed hosting services and proprietary mining in which 10 megawatts were used for hosting services and 10 megawatts was used for proprietary mining through the end of February 2023, at which time the facility had been decommissioned. In the second quarter of fiscal year 2023, Project Sophie entered into hosting contracts with Bitcoin miners, which marked a shift in the Company’s business model at the Company’s modular data centers at Project Sophie from proprietary mining to hosting Bitcoin miners for the customers for 25 MegaWatt (“MW”). As of December 31, 2023, all of Project Sophie is performing data hosting. The Company has sold most of its existing Bitcoin miners at the Project Sophie site and redeploying capital. On September 17, 2022, SCI sold specified assets consisting mainly of mining equipment and other general equipment items to a buyer at its Wenatchee, Washington location, (“Project Edith”). Soluna has committed to providing certain facilities contracts at cost plus a markup to facilitate the continued operations for the sold mining assets, on behalf of the new ownership. Our Texas site (“Project Dorothy”) is located at a wind farm and has a potential for up to 100 MWs, of which the Company obtained approval from the Electric Reliability Council of Texas (“ERCOT”) and energized 25 MW in May 2023 and has energized another 25 MW in October 2023. The Company as of December 31, 2023, has a 14.6 51 Until the Sale (as defined below), we also operated though our wholly owned subsidiary, MTI Instruments, an instruments business engaged in the design, manufacture and sale of vibration measurement and system balancing solutions, precision linear displacement sensors, instruments and system solutions, and wafer inspection tools. MTI Instruments was incorporated in New York on March 8, 2000. MTI Instruments’ products consisted of engine vibration analysis systems for both military and commercial aircraft and electronic gauging instruments for position, displacement and vibration application within the industrial manufacturing markets, as well as in the research, design and process development markets. These systems, tools and solutions were developed for markets and applications that require consistent operation of complex machinery and the precise measurements and control of products, processes, and the development and implementation of automated manufacturing and assembly. On December 17, 2021, we announced that we had entered into a non-binding letter of intent with a potential buyer (the “Buyer”) regarding the potential sale of MTI Instruments (the “LOI”) to an unrelated third party. Pursuant to the LOI, the Buyer would acquire 100 On April 11, 2022, SHI entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with NKX Acquiror, Inc. (the “Purchaser”), pursuant to which the Company sold on such date all of the issued and outstanding shares of capital stock of its wholly-owned subsidiary, MTI Instruments, for approximately $ 9.4 10.75 7.8 Going Concern and Liquidity The Company’s financial statements as of December 31, 2023 have been prepared using generally accepted accounting principles in the United States of America (“U.S. GAAP”) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As shown in the accompanying consolidated financial statements, the Company did not generate sufficient revenue to generate net income and has a cash used in operations position during the year ending as of December 31, 2023. In addition, the Company has ceased operations for Project Marie in February 2023 due to the termination of the Management and Hosting Services agreement with CC Metals and Alloys, LLC (“CCMA”) and repossession of collateral for miners as discussed further below. These factors, among others indicate that there is substantial doubt about the Company’s ability to continue as a going concern within one year after issuance of these financial statements as of December 31, 2023, or April 1, 2024. Soluna MC Borrowing 2021-1 (the “Borrower”), received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG ABL LLC (“NYDIG”) with respect to the Master Equipment Finance Agreement, dated as of December 30, 2021 (the “MEFA”), by and between Borrower and NYDIG. The NYDIG Notice states that (a) Borrower failed to observe or perform certain covenants, conditions or agreements contained in the MEFA and such failure continued unremedied for a period of ten days after Borrower’s knowledge of such breach, which resulted in an event of default under the MEFA, and (b) Borrower defaulted under the guaranty, collateral agreement, or other support agreement, which resulted in an event of default under the MEFA. In addition, the NYDIG Notice states that Borrower failed to pay certain payments of principal and interest under the MEFA when due, which failure also constituted an event of default under the MEFA. As a result of the foregoing events of default, and pursuant to the MEFA, NYDIG (x) declared the principal amount of all loans due and owing under the MEFA and all accompanying Loan Documents (as defined in the MEFA) to be due and immediately payable, (y) imposed a default rate of interest on any outstanding principal amount of each loan (together with all then unpaid interest accruing thereon) and all other obligations under the MEFA and the Loan Documents, and (z) demanded the return of all equipment subject to the MEFA and the Loan Documents. The obligations of Borrower under the MEFA and reflected in the NYDIG Notice were ring-fenced to Borrower and its direct parent company, Soluna MC LLC. On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, which resulted in a reportable disposition of all of the Company’s mining assets at the site and certain of the operating assets of Project Marie. The total net book value of the collateralized assets that were repossessed totaled approximately $ 3.4 9.2 936 The ability to continue as a going concern is dependent upon the Company generating profitable operations in the future and/or obtaining the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. In the near term, management is evaluating and implementing different strategies to obtain financing to fund the Company’s expenses and growth to achieve a level of revenue adequate to support the Company’s current cost structure. Financing strategies may include, but are not limited to, stock issuances, project level equity, debt borrowings, partnerships and/or collaborations. If the Company is unable to meet its financial obligations, it could be forced to restructure or refinance, seek additional equity capital or sell its assets. The Company might then be unable to obtain such financing or capital or sell its assets on satisfactory terms. There can be no assurance that additional financing will be available to the Company when needed or, if available, that it can be obtained on commercially reasonable terms. If the Company is not able to obtain the additional financing on a timely basis, if and when it is needed, it will be forced to delay or scale down some or all of its development activities or perhaps even cease the operation of its business. To further implement management’s strategy, in May 2022, SCI entered into a structural understanding with Soluna SLC Fund I Projects Holdco LLC (“Spring Lane”), a Delaware limited liability company, pursuant to which Spring Lane agreed to provide up to $ 35.0 12.5 35.0 32 4.8 7.5 32 85.4 68 14.6 In addition, on May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DVCC”) through Soluna DV Devco, LLC completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC , 12.1 51 49 Between January 24, 2023 and April 3, 2023, the Company had the first and partial second subsequent closings under the Securities Purchase Agreement dated December 5, 2022, among the Company and certain institutional investors. Pursuant to the SPA, the investors purchased approximately $ 886 117,097 234,195 774,000 7.50 103,183 206,367 For the year-ended December 31, 2023, the Company has sold under-utilized miners and equipment, and continues to evaluate opportunities to sell more miners and equipment for fiscal year 2024. In addition to the proceeds from the foregoing transactions and together with the Company’s available cash on hand for available use of approximately $ 6.4 112

Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation In the opinion of management, the Company’s condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair statement of the results for the periods presented in accordance with United States of America’s Generally Accepted Accounting Principles (“U.S. GAAP”). The results of operations for the interim periods presented are not necessarily indicative of results for the full year. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (“the Annual Report”). The information presented in the accompanying condensed consolidated balance sheet as of December 31, 2023 has been derived from the Company’s audited consolidated financial statements. All other information has been derived from the Company’s unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2024 and September 30, 2023. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, including the Company’s variable interest entities disclosed in Note 13. All intercompany balances and transactions are eliminated in consolidation. Reverse Stock Split On October 11, 2023, the Company filed a Certificate of Change (the “Certificate of Change”) effecting a reverse stock split as of 5:00 p.m. Eastern Standard Time on October 13, 2023 with a ratio of 1-for-25 every 25 issued and outstanding shares of the Company common stock was converted automatically into one share of the Company’s common stock without any change in the par value per share. The primary goal of the Reverse Stock Split was to increase the per share price of the Common Stock in order to meet the minimum per share price requirement of $ 1.00 In addition, effective as of the same time as the Reverse Split, proportionate adjustments were made to all then-outstanding equity awards, warrants and convertible securities with respect to the number of shares of common stock subject to such award or security and the exercise or conversion price thereof. Furthermore, the number of shares of common stock available for issuance under the Company’s equity incentive plans has been proportionately adjusted for the Reverse Split ratio, such that fewer shares will be subject to such plans. Furthermore, proportionate adjustments were made to the conversion factor at which the Company’s Series B Preferred Stock, par value $ 0.0001 187,500 The effects of the Reverse Stock Split have been reflected in these financial statements and the accompanying footnotes for all periods presented, which includes adjusting the description of any activity that may have been transacted on a pre-Reverse Stock Split basis. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months. Restricted Cash Restricted cash relates to cash that is legally restricted as to withdrawal and usage or is being held for a specific purpose and thus not available to the Company for immediate or general business use. As of September 30, 2024, the Company had restricted cash of approximately $ 3.4 2.0 1.46 4.0 3.0 1.0 Deposits and Credits on equipment As of September 30, 2024 and December 31, 2023, the Company had approximately $ 5.0 1.0 975 49 926 Warrant Liability Under the guidance in ASC 815, Derivatives and Hedging As discussed in Footnote 7, on June 20, 2024, Soluna AL Cloudco, LLC (“CloudCo”), a subsidiary of Soluna Cloud, Inc (“Cloud”), entered into a Promissory Note Agreement of $ 12.5 1.25 0 Reclassification Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations or net assets. Correction of an Error While preparing the Company’s Form 10-K for the year ended December 31, 2023, the Company identified the following errors related to the presentation of basic and diluted Earnings Per Share (“EPS”) in its historical filing for the year ended December 31, 2022, and for the quarters ended March 31, 2023, June 30, 2023, and September 30, 2023: ● Inclusion of the net income/loss from noncontrolling interest in the numerator; ● Inclusion of the cumulative undeclared preferred dividends in the numerator; ● Exclusion of shares issued for little or no cash consideration (ie: penny warrants) in the denominator. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements;” the Company evaluated the errors and has determined that the related impacts were not material to any prior annual or 10-Q report, but that correcting the cumulative impact of such errors would be significant to our EPS for the year ended December 31, 2023. Accordingly, the Company has corrected such immaterial errors by adjusting its December 31, 2022 consolidated statement of operations related to the calculation of earnings per share. The Company also corrected previously reported interim financial information for such immaterial errors in future filings, as applicable. The following summarizes the effect of the revision on each financial statement line item. The following analysis provides a comparison amongst the basic and diluted EPS as reported on the Form 10-Q for the quarter ended September 30, 2023, and the final revised basic and diluted EPS calculation to correct all identified errors: Schedule of Error Corrections of Basic and Diluted EPS For the three months ended For the nine months ended As Reported As Revised Change As Reported As Revised Change Basic and Diluted net loss per share $ (4.40 ) $ (5.96 ) $ (1.56 ) $ (20.11 ) $ (24.16 ) $ (4.05 )	2.

Actual results could differ from those estimates. Property, Plant, and Equipment Property, plant and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives as follows: Schedule of Property Plant and Equipment Estimated Useful Lives Leasehold improvements Lesser of the life of the lease or the useful life of the improvement Computers and related software 3 5 Cryptocurrency miners 3 Machinery and equipment 8 15 Office furniture, equipment and fixtures 2 10 Buildings 30 40 Purchased pre-fabricated buildings 15 20 Significant additions or improvements extending assets’ useful lives are capitalized; normal maintenance and repair costs are expensed as incurred. The costs of fully depreciated assets remaining in use are included in the respective asset and accumulated depreciation accounts. When items are sold or retired, related gains or losses are included in net (loss) income. Intangible assets Intangible assets include the Strategic Pipeline Contract with an estimated useful life of 5 5 15 25 Income Taxes The Company is subject to income taxes in the U.S. (federal and state). As part of the process of preparing our consolidated financial statements, the Company calculates income taxes for each of the jurisdictions in which the Company operates. This involves estimating actual current taxes due together with assessing temporary differences resulting from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities, loss carryforwards and tax credit carryforwards, for which income tax benefits are expected to be realized in future years. A valuation allowance has been established to reduce deferred tax assets, if it is more likely than not that all, or some portion, of such deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. Significant management judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against the Company’s net deferred tax assets. The Company considers all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income amongst other items in determining the Company’s valuation allowance. In addition, the Company’s assessment requires the Company to schedule future taxable income in accordance with accounting standards that address income taxes to assess the appropriateness of a valuation allowance, which further requires the exercise of significant management judgment. The Company accounts for taxes in accordance with the asset and liability method of accounting for income taxes. Under this method, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution The Company is currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or in applicable laws, regulations, administrative practices, principles, and interpretations could have a material effect on the Company’s operating results or cash flows in the period or periods in which such developments occur, as well as for prior and in subsequent periods. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating the Company’s provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. The Company’s effective tax rates could be affected by numerous factors, such as intercompany transactions, earnings being lower than anticipated in jurisdictions where the Company has lower statutory rates and higher than anticipated in jurisdictions where the Company has higher statutory rates, the applicability of special tax regimes, losses incurred in jurisdictions for which the Company is not able to realize the related tax benefit, changes in foreign currency exchange rates, entry into new businesses and geographies, changes to its existing businesses and operations, acquisitions and investments and how they are financed, changes in the Company’s stock price, changes in its deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations. Equity Investment – Harmattan Energy Limited The Company owns approximately 1.79 0 Equity Investments without Readily Determinable Fair Values Our equity investment in HEL is accounted for under the measurement alternative. Equity securities measured and recorded using the measurement alternative are recorded at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes. Adjustments resulting from impairments and observable price changes are recorded in the income statement. There was an impairment recognized for the full amount of $ 750 Equity Method Investments The Company’s consolidated net income or loss will include our proportionate share, if any, of the net income or loss of our equity method investee. When the Company records its proportionate share of net income, it increases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. Conversely, when the Company records its proportionate share of a net loss, it decreases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. When the Company’s carrying value in an equity method investee company has been reduced to zero, no further losses are recorded in the Company’s financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized. As of December 31, 2023, the Company owned approximately 47.5 75,049,937 240,000,000 0 Variable Interest Entities Variable Interest Entities (“VIEs”) are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the entity’s expected losses, or the right to receive the entity’s expected residual returns. The Company consolidates a VIE when it is the primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) through its interests in the VIE, the obligation to absorb expected losses or the right to receive expected benefits from the VIE that could potentially be significant to the VIE. The Company consolidates the accounts of Soluna DVSL ComputeCo, LLC (“DVSL”) and Soluna DV ComputeCo, LLC (“DVCC”), each a VIE. The Company held a 67.8 14.6 100 51 Non-Controlling Interests The ownership interest held by owners other than the Company in less than wholly-owned subsidiaries are classified as non-controlling interests. The value attributable to the non-controlling interests is presented on the consolidated balance sheets separately from the equity attributable to the Company. Net income (loss) attributable to non-controlling interests are presented separately on the consolidated statements of operations and consolidated statements of comprehensive income, respectively. Fair Value Measurement The estimated fair value of certain financial instruments, including cash, accounts receivable and short-term debt approximates their carrying value due to their short maturities and varying interest rates. “Fair value” is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation methods, the Company is required to provide the following information according to the fair value accounting standards. These standards established a fair value hierarchy as specified that ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities are classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities, which includes listed equities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. These items are typically priced using models or other valuation techniques. These models are primarily financial industry-standard models that consider various assumptions, including the time value of money, yield curves, volatility factors, as well as other relevant economic measures. Level 3: These use unobservable inputs that are not corroborated by market data. These values are generally estimated based upon methodologies utilizing significant inputs that are generally less observable from objective sources. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. On October 25, 2021, pursuant to a securities purchase agreement dated October 20, 2021 (the “SPA), the Company issued to certain accredited investors Class A, Class B and Class C common stock purchase warrants (collectively, the “Warrants”) to purchase up to an aggregate of 71,043 312.50 375 450 As noted in Note 9, the Company entered into an Addendum and Addendum Amendment in which the Company surrendered their Class B and Class C warrants in July and September 2022, in exchange for Class D common stock purchase warrants at an exercise price of $ 87.50 112.50 137.50 187.50 56.00 54.50 53.25 52.00 240,000 12.50 80,000 20.00 4.20 4.03 Any modifications of the warrants were subsequently revalued, including the warrants attached to the Third Amendment on November 20, 2023, see Note 9 for details. Inherent in a Black-Scholes simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from its traded warrants and historical volatility of select peers’ common stock with a similar expected term of the Warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield on the grant date with a maturity similar to the expected remaining term of the warrants. The expected term of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company expects to remain at zero. The warrants were collectively classified as a Level 3 measurement within the fair value hierarchy because these valuation models involve the use of unobservable inputs relating to the Company’s estimate of its expected stock volatility which was developed based on the historical volatility of a publicly traded set of peer companies. The following table represents the significant fair value assumptions used for warrants issued or repriced during the years ended December 31, 2023 and 2022: Schedule of Fair Value Assumptions For Warrants Issued 2023 2022 Stock price (1) $ 2.93 5.00 $ 14.25 259.25 Exercise price (1) $ 0.01 20.00 $ 19.00 331.50 Expected term in years 1.16 5.00 2.00 5.00 Expected dividend yield 0.00 % 0.00 % Volatility 108.50 140 % 125 150 % Risk-free interest rate 3.36 5.25 % 1.18 4.41 % (1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for- 25 Following the debt extinguishment on July 19, 2022 as noted further in Note 9, the Convertible Notes will be accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. The Company had a subsequent Addendum Amendment on September 13, 2022, a Second Amendment on May 11, 2023, and a Third Amendment on November 20, 2023, which each caused a revaluation of the fair value on the executed Addendum Amendment, Second Amendment, and Third Amendment date. Although the Notes are not being accounted for under 825-10, the substance of the debt is considered to be the same and is therefore considered outside the scope of ASC 470-60. As such, the Company performed a fair value analysis of the Convertible Notes. For the year-ended December 31, 2022 and 2023, the Company had Monte Carlo simulations run-out for the expected conversion dates of the Convertible Notes using risk free rates, annual volatility, daily trading volumes, likely conversion profiles, and other assumptions based on principal and accrued interest as of the year-end. The Company determined the fair value of the Convertible Notes uses certain Level 3 inputs. The following table represents the significant and subjective fair value assumptions used for Convertible Notes during the years ended December 31, 2023 and 2022: Schedule of Fair Value Assumptions For Convertible Notes 2023 2022 Stock price (1) $ 3.60 6.75 $ 6.5 Conversion price (1) $ 3.78 7.99 $ 7.99 Volatility 87.50 150 % 65 105 % Risk-free interest rate 4.64 5.50 % 4.12 4.76 % (1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for- 25 Changes in Level 3 Financial Liabilities Carried at Fair Value Schedule of Changes in Level 3 Financial Liabilities Carried at Fair Value (in thousands) Balance, July 19, 2022 (date of Addendum of convertible notes) $ 14,610 Conversions of debt (1,100 ) Total revaluation loss 597 Balance, September 13, 2022 14,107 Total revaluation gains (1,853 ) Balance, December 31, 2022 $ 12,254 Conversions of debt (January 2023- May 11 2023) (1,344 ) Total revaluation losses 30 Balance, May 11, 2023 (date of Second Amendment) 10,940 Conversions of Debt (May 11, 2023-November 19, 2023) (1,550 ) Total revaluation losses 1,569 Balance November 20, 2023 (date of Third Amendment) $ 10,959 Financial liabilities , Beginning balance $ 10,959 Conversions of debt (November 20, 2023- December 31, 2023) (3,069 ) Conversions of debt (3,069 ) Total revaluation losses 584 Total revaluation (gains) losses 584 Balance December 31, 2023 $ 8,474 Financial liabilities, Ending balance $ 8,474 Consistent with the guidance in purchase accounting, the value of the pipeline of certain cryptocurrency mining projects previously owned by HEL acquired in the Soluna Callisto acquisition in October 2021 as of the acquisition date was estimated using an expected value approach, which probability-weights various future outcomes and uses certain Level 3 inputs. Included in those inputs are the following key assumptions: expected growth in share price at a risk-free rate in the risk-neutral framework based on U.S. Treasury Rates as of the valuation date, volatility of share price based on historical equity volatilities of comparable companies over a lookback period, assessments associated with qualified projects based on assessment on timing of payments and assessment of active megawatt scenarios and the associated probabilities. The resulting amounts are then discounted to present value through use of a discount rate that considers, among other things, the risk of the payments, credit risk of the Company, and overall weighted average cost of capital of the acquired business. The resulting calculations resulted in an estimated fair value of the acquired assets and consideration paid in common stock of approximately $ 33 3.5 Revenue Recognition Cryptocurrency Mining Revenue The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principles of the revenue standard are that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the company expects to be entitled for those goods or services. The following five steps are applied to achieve that core principle: ● Step 1: Identify the contract with the 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 the Company satisfies a performance obligation In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract). If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct. The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following: ● Variable consideration ● Constraining estimates of variable consideration ● The existence of a significant financing component in the contract ● Noncash consideration ● Consideration payable to a customer Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time. Providing computing power to solve complex cryptographic algorithms in support of the Bitcoin blockchain (in a process known as “solving a block”) is an output of the Company’s ordinary activities. The provision of providing such computing power is the only performance obligation in the Company’s contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block (by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue is recognized. There is no significant financing component in these transactions. Fair value of the cryptocurrency award received is determined using the quoted price of the related cryptocurrency where the Company is registered at the time of receipt. The mined cryptocurrency is immediately paid to the Coinbase and Bittrex wallet. Cryptocurrency is converted to U.S. dollars nearly everyday, as SCI is not in the business of accumulating material amounts of cryptocurrency on its balance sheet. Data center hosting The Company has entered customer hosting contracts whereby the Company provides electrical power and network connectivity to cryptocurrency mining customers, and the customers pay a stated amount per megawatt-hour (“MWh”) (“Contract Capacity”), a fixed rate, as well as a percentage of the profit share of net income from the customer’s mining operations. The actual monthly amounts are calculated after the close of each month and billed the customer. If any shortfalls due to outages are experienced, service level credits may be made to customers to offset outages which prevented them from cryptocurrency mining. Customer contract security deposits are reflected as other liabilities and are made at the time the contract is signed and held until the conclusion of the contract relationship Deferred revenue is primarily from advance monthly payments received and revenue is recognized when service is completed. Demand Response Service The Company provides emergency demand response solutions to ERCOT pursuant to a contractual commitment over defined service delivery periods. This contract includes a single promise to stand ready, on a monthly basis, to deliver a set amount of curtailment (committed capacity) per month when and if called upon by ERCOT. The Company has concluded this represents a series of distinct monthly services that are substantially the same, with the same pattern of transfer to the customer. Accordingly, the monthly promise to stand ready is accounted for as a single performance obligation. The Company is the principal in these arrangements as it has control over the services prior to those services being transferred to the customer. Capacity fees are paid to the Company by ERCOT for its stand ready commitment to curtail MWs and are typically based on the Company’s ability to deliver the committed capacity throughout the contractual delivery period. In general, if the Company fails to curtail the contracted MW during energy or emergency dispatches, the MW shortfall results in a penalty that could require the Company to reduce the fees paid by the customer during the contract period. In order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. These estimates consider i) the contractual rate per MW, and ii) historical performance. The Company constrains (reduces) the estimates of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required. In the event of an emergency dispatch, any earned energy fees are associated and allocated to the specific month of performance, as these fees meet the criteria to allocate variable consideration to a distinct monthly service within a series of distinct services that comprise the single performance obligation. Therefore, energy fees are recognized in the month in which the Company is called upon to deliver on its stand-ready obligation to curtail capacity. The Company believes that an output measure based on the monthly contractual MW stand-ready obligation is the best representation of the “transfer of value” to the customer. Accordingly, the Company recognizes monthly revenue based on the proportion of committed stand-ready capacity obligation that has been fulfilled to date. Cost of Cryptocurrency Mining and Data Center Hosting Revenue Cost of cryptocurrency mining and data center hosting revenue includes direct utility costs as well as overhead costs that relate to the operations of SCI’s cryptocurrency mining facility. Accounts Receivable and Allowance The Company’s accounts receivable balance consists of amounts due from its data center hosting customers and receivables for demand response services. The Company records accounts receivable at the invoiced amount less an allowance for any potentially uncollectable accounts under the current expected credit loss (“CECL”) impairment model and presents the net amount of the financial instrument expected to be collected. The CECL impairment model requires an estimate of expected credit losses, measured over the contractual life of an instrument, that considers forecasts of future economic conditions in addition to information about past events and current conditions. Based on this model, the Company considers many factors, including the age of the balance, collection history, and current economic trends. The Company determines the allowance based on historical write-off experience and current exposures identified. The Company reviews its allowance for potentially uncollectible accounts under CECL monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered. The Company does not have any off balanc

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Asset Acquisition	5. Asset Acquisition As discussed above, on October 29, 2021, we completed the Soluna Callisto acquisition pursuant to an Agreement and Plan of Merger dated as of August 11, 2021, by and among the Company, SCI and Soluna Callisto (the “Merger Agreement”). The purpose of the transaction was for SCI to acquire substantially all of the assets (other than those assets physically located in Morocco) formerly held by HEL, which assets consisted of Soluna Callisto’s existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to Soluna Callisto and to provide SCI with the opportunity to directly employ or retain the services of four individuals whose services it had retained through HEL prior to the merger. As a result of the merger, each share of common stock of Soluna Callisto issued and outstanding immediately prior to the effective time of the merger, other than shares owned by the Company or any of our subsidiaries, was cancelled and converted into the right to receive a proportionate share of up to 118,800 The acquisition was accounted for, for purposes of U.S. GAAP, using the asset acquisition method of accounting under the ASC 805-50. We determined that we acquired in the acquisition a group of similar identifiable assets (primarily, the “strategic pipeline contract” of certain cryptocurrency mining projects), which it classified as an intangible asset for accounting purposes. As a result, our acquisition of the set of assets and activities constituted an asset acquisition, as opposed to a business acquisition, under ASC 805. ASC 805-50 provides that assets acquired in an asset acquisition are measured based on the costs of the acquisition, which is the consideration that the acquirer transfers to the seller and includes direct transaction costs related to the acquisition. We include Soluna Callisto’s results of operations in our results of operations beginning on the effective date of the acquisition. Termination Consideration In connection with the Soluna Callisto acquisition, effective as of October 29, 2021, pursuant to the terms of a termination agreement dated as of August 11, 2021 by and among the Company, SCI, and HEL, on November 5, 2021, SCI paid HEL $ 725 6,000 75 1.9 Merger Consideration The fair value of the Merger Consideration includes various assumptions, including those related to the allocation of the estimated value of the maximum number of Merger Shares ( 118,800 1a) Upon the Company achieving each one active MegaWatts (“Active MWs”) from the projects in which the cost requirement is satisfied, this will cause SHI to issue to HEL 792 shares for each one MW up to a maximum 150 Active MW i. If, on or before June 30, 2022, SCI or Soluna Callisto directly or indirectly achieves at least 50 active MWs from one or more of three current projects as set forth in the Merger Agreement that satisfy the Cost Requirement as defined within the Merger Agreement, then the Merger Shares will be issued at an accelerated rate of 1,188 Merger Shares for each of such first 50 Active MW, such that the Merger Shares in respect of the remaining 100 Active MWs (if any) will be issued at a reduced rate of 594 Merger Shares per Active MW (see below for extension and issuance of a proportion of shares) ii. If, by June 30, 2023, SCI or Soluna Calisto fail to achieve directly or indirectly (other than pursuant to a Portfolio Acquisition) at least 50 Active MW from Projects that satisfy the Cost Requirement, then the maximum aggregate number of Merger Shares shall be reduced from 118,800 to 59,400 (see below for extension and issuance of a proportion of shares) iii. No Merger Shares will be issued to HEL without our prior written consent; iv. Issuance of the Merger Shares will also be subject to the continued employment with or engagement by SCI or the surviving corporation of (A) John Belizaire and (B) at least two of Dipul Patel, Mohammed Larbi Loudiyi, (through ML&K Contractor), and Phillip Ng at the time that such Merger Shares are earned. If both (A) and (B) cease to be satisfied on or prior to the date that all Merger Shares are earned (such date, a “Trigger Date”), then “Qualified Projects” for purposes of determining Merger Shares shall only apply to those Qualified Projects that are in the pipeline as of the Trigger Date. For these purposes, if any such individual’s employment or service relationship with SCI is terminated without cause, as a result of his death or disability, or with good reason (as such terms are defined in the employment and consulting agreements), such individual shall be deemed to continue to be employed or engaged by SCI for these purposes; v. If SHI or SCI consummates a Change of Control before the fifth anniversary of the date of the closing of the merger, then we will be obligated to issue all of the unissued Merger Shares (subject to (ii) and (iii) above). The Merger Agreement defines “Change of Control” as (A) the sale, exchange, transfer, or other disposition of all or substantially all of the assets of us or SCI, (B) our failure to continue to own (directly or indirectly) 100 50 vi. if on any of the fifth anniversary of the effective time of the merger, a facility has not become a Qualified Facility and therefore is not taken into consideration in the calculation of Active MW because any of the elements set forth in the definition of “Qualified Facility” as defined in the Merger Agreement have not been met for reasons beyond the reasonable control of SCI’s management team, but SCI’s management team is then actively engaged in the process of completing and is diligently pursuing the completion of the missing elements, then (A) the target dates set forth above shall be extended for an additional 90 days, and (B) additional extensions of time may be granted by the Board of Directors in its commercially reasonable discretion, in each case for the purpose of enabling SCI’s management team to complete the steps needed to qualify the facility as a Qualified Facility. On April 11, 2023, the Board had reviewed and approved the progress of SCI’s management team in qualifying facilities as Qualified Facilities and discussed an extension of the date in Section 2.7(a)(ii)(A) of the Merger Agreement to December 31, 2023 (previously was June 30, 2022), and an extension of the date in Section 2.7(a)(ii)(B) of the Merger Agreement to June 30, 2024 (previously was June 30, 2023). Due to conditions being met within the Merger Agreement in relation to energization and retention of employees, the Company has advised SCI US Holdings LLC, a Delaware limited liability company, who is the sole Effective Time Holder (as defined in the Merger Agreement) of the right to receive the Merger Shares and that 19,800 39,600 59,400 59,400 The number of Merger Shares is also subject to customary anti-dilution adjustments in the event of any stock split, stock consolidation, stock dividend, or similar event involving the shares of our common stock. Based on the assessment performed, the fair value of the merger consideration as of October 29, 2021 was approximately $ 33.0 Based on management’s evaluation, management concluded that due to the high volatility of its share price, the low probability of not achieving the MW targets, and the fact the value associated with meeting the performance measures are not intended to drive the number of shares to be issued, but rather act as a proxy for and driver of share value, the monetary value of the obligation at inception is predominantly a function of equity shares. As such, the consideration will be treated as equity as ASC 480-10-25-14 is not applicable since the monetary value of the Merger Shares is not (1) fixed, or (2) dependent on (i) variations in something other than the fair value of the Company’s equity shares, or (ii) variations inversely related to changes in the fair value of the Company’s equity shares and is instead exposed to changes in the fair value of the Company’s share price, and as such does not represent a liability under ASC 480. The economic risks and characteristics of the share consideration are clearly and closely related to a residual equity interest since the underlying (i.e., the incremental shares of common stock delivered upon achievement of each MW target) will participate in the increase in value of the common equity of the Company, similar to a call option on common stock. Based on guidance in ASC 815-40-25-7 through 25-35, the share consideration is considered to be indexed to the Company’s stock and meets the additional criteria for equity classification.

Income Taxes During the three and nine months ended September 30, 2024, the Company’s effective income tax rate was 8.3 7.6 (4.5) 1.6 21 547 569 1.8 524 63 0 In connection with the strategic contract pipeline acquired in the asset acquisition that occurred in October 2021, the Company is required to recognize a deferred tax impact of acquiring an asset in a transaction that is not a business combination when the amount paid exceeds the tax basis on the acquisition date. As such, the Company is required to adjust the value of the strategic contract pipeline by approximately $ 10.9 547 1.6 The Company provides for recognition of deferred tax assets if the realization of such assets is more likely than not to occur in accordance with accounting standards that address income taxes. Significant management judgment is required in determining the period in which the reversal of a valuation allowance should occur. The Company has considered all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income amongst other items, in determining its valuation allowance. In addition, the Company’s assessment requires us to schedule future taxable income in accordance with accounting standards that address income taxes to assess the appropriateness of a valuation allowance which further requires the exercise of significant management judgment. The Company believes that the accounting estimate for the valuation of deferred tax assets is a critical accounting estimate because judgment is required in assessing the likely future tax consequences of events that have been recognized in our financial statements or tax returns. The Company based the estimate of deferred tax assets and liabilities on current tax laws and rates and, in certain cases, business plans and other expectations about future outcomes. In the event that actual results differ from these estimates, or the Company adjusts these estimates in future periods, the Company may need to adjust the recorded valuation allowance, which could materially impact our financial position and results of operations. The Company has a full valuation allowance for the deferred tax asset of $ 36.7 36.8	7.

As such, the Company is required to adjust the value of the strategic contract pipeline by approximately $ 10.9 Valuation Allowance: The Company believes that the accounting estimate for the valuation of deferred tax assets is a critical accounting estimate because judgment is required in assessing the likely future tax consequences of events that have been recognized in our financial statements or tax returns. The Company based the estimate of deferred tax assets and liabilities on current tax laws and rates and, in certain cases, business plans and other expectations about future outcomes. As a result of its assessment in 2023, the Company increased its valuation allowance against its deferred tax assets. The increase in the valuation allowance caused incremental tax expense of $ 6.1 The valuation allowance on December 31, 2023 and 2022 was $ 36.8 30.7 Schedule of Deferred Tax Asset Valuation Allowance (Dollars in thousands) 2023 2022 Valuation allowance, beginning of year $ 30,651 $ 11,921 Net operating (loss) income 9,813 7,361 Property, plant and equipment (4,316 ) 10,093 Stock options 566 996 Research and development credit 53 30 Accrued expenses 24 250 Valuation allowance, end of year $ 36,791 $ 30,651 Net operating losses: As of December 31, 2023, the Company has unused Federal net operating loss carryforwards of approximately $ 126.2 52 The Company’s and/or its subsidiaries’ ability to utilize their net operating loss carryforwards may be significantly limited by Section 382 of the IRC of 1986, as amended, if the Company or any of its subsidiaries undergoes an “ownership change” as a result of changes in the ownership of the Company’s or its subsidiaries’ outstanding stock pursuant to the exercise of the warrants or otherwise. Unrecognized tax benefits: The Company has unrecognized tax benefits of $ 0 0 Additionally, the Company does not have uncertain tax positions that it expects will increase or decrease within twelve months of this reporting date. The Company recognizes interest and penalties related to uncertain tax positions as a component of tax expense. The Company did not recognize any interest or penalties in 2023 and 2022. The Company files income tax returns, including returns for its subsidiaries, with federal and state jurisdictions. The Company is no longer subject to IRS or state examinations for any periods prior to 2019, although carryforward attributes that were generated prior to 2021 may still be adjusted upon examination by the IRS if they either have been or will be used in a future period.

Pursuant to the Addendum and Addendum Amendment, the Company evaluated whether the new addendums qualified as debt modification or debt extinguishment. Based on ASC 470, Debt, the Company determined the Addendum and Addendum Amendment to fall under Debt Extinguishment treatment and the Company would be required to fair value the new debt, and in turn write off the existing debt on the books. Following the debt extinguishment on July 19, 2022 as noted above, the Convertible Notes will be accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. Although the Notes are not being accounted for under 825-10, the substance of the debt is considered to be the same and is therefore considered outside the scope of ASC 470-60. As such, the Company performed a fair value analysis of the Convertible Notes. For the year-ended December 31, 2023 and quarter-ended September 30, 2024, the Company ran Monte Carlo simulations for the expected conversion dates of the Convertible Notes using risk free rates, annual volatility, daily trading volumes, likely conversion profiles, and other assumptions based on principal and accrued interest as of the period ends.

Diluted loss per share reflects the potential dilution, if any, computed by dividing loss by the combination of dilutive common share equivalents, comprised of shares issuable under outstanding investment rights, warrants and the Company’s share-based compensation plans, and the weighted average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money stock options, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of a stock option and the amount of compensation cost, if any, for future service that the Company has not yet recognized are assumed to be used to repurchase shares in the current period.

Stock Based Compensation	11. Stock Based Compensation 2023 Plan The 2023 Plan was adopted by the Board on February 10, 2023 and approved by the stockholders on March 10, 2023. The 2023 Plan sets the number of shares of our Common Stock reserved for issuance thereunder, on a quarterly basis, to 9.75 9.75 On June 29, 2023, at the Annual Shareholder Meeting, the Amended and Restated 2023 Stock Incentive Plan was approved. The Amended and Restated 2023 Plan will, among other things, increase the number of shares of our Common Stock reserved for issuance thereunder, on a quarterly basis, to 23.75 23.75 2021 Plan The Company’s 2021 Plan was adopted by the Board on February 12, 2021 and approved by the stockholders on March 25, 2021. The 2021 Plan was amended and restated effective as of October 29, 2021, and May 27, 2022, respectively. The 2021 Plan authorizes the Company to issue shares of common stock upon the exercise of stock options, the grant of restricted stock awards, and the conversion of restricted stock units (collectively, the “Awards”). The Compensation Committee has full authority, subject to the terms of the 2021 Plan, to interpret the 2021 Plan and establish rules and regulations for the proper administration of the 2021 Plan. Subject to certain adjustments as provided in the 2021 Plan, the maximum aggregate number of shares of the Company’s common stock that may be issued under the 2021 Plan (i) pursuant to the exercise of options, (ii) as shares or restricted stock and (iii) in settlement of RSUs shall be limited to (A) during the Company’s fiscal year ending December 31, 2021 (the “2021 Fiscal Year”), 1,460,191 15 15 On March 10, 2023, at the Special Shareholder Meeting, the Third Amended and Restated 2021 Stock Incentive Plan was approved. The Third Amended and Restated 2021 Plan will, among other things, (a) increase the number of shares of our Common Stock reserved for issuance thereunder, on a quarterly basis, to 18.75% of the shares of our Common Stock outstanding on the measurement date and (b) allow us to grant awards of shares of our 9.0% Series A Cumulative Perpetual Preferred Stock (“Series A Preferred Stock”) (with and without restrictions). Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, the maximum aggregate number of shares of our Common Stock that may be issued under the Third Amended and Restated 2021 Plan (excluding the number of shares of our Common Stock subject to Specified Awards (as defined below)) (i) pursuant to the exercise of stock options, (ii) as unrestricted or restricted Common Stock, and (iii) in settlement of RSUs shall be limited to, beginning with the first quarter of our fiscal year ending December 31, 2023 (or January 1, 2023), 18.75% of the number of shares of our Common Stock outstanding as of the first trading day of each quarter. Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, the maximum aggregate number of shares of our Series A Preferred Stock that may be issued under the Third Amended and Restated 2021 Plan as unrestricted or restricted Series A Preferred Stock shall equal $3,600,000 valued as of the effective date of the Third Amended and Restated 2021 Plan as determined at the lower of the closing price of our Series A Preferred Stock on Nasdaq on such date or the average of the daily volume weighted average price of our Series A Preferred Stock on Nasdaq as reported by Bloomberg L.P. for a period of five (5) consecutive trading days ending on such date. Subject to certain adjustments as provided in the Third Amended and Restated 2021 Plan, (i) shares of our Common Stock and Series A Preferred Stock, as applicable, subject to the Third Amended and Restated 2021 Plan shall include shares of our Common Stock and Series A Preferred Stock, as applicable, which revert back to the Third Amended and Restated 2021 Plan in a prior quarter or fiscal year, as applicable, pursuant to the paragraph below, and (ii) the number of shares of our Common Stock and Series A Preferred Stock, as applicable, that may be issued under the Third Amended and Restated 2021 Plan may never be less than the number of shares of our Common Stock and Series A Preferred Stock, as applicable, that are then outstanding under (or available to settle existing) 2021 Plan Award grants. For purposes of the Third Amended and Restated 2021 Plan, “Specified Awards” means (i) 2021 Plan Awards issued to Eligible Persons who are not employed or engaged by us or any of our subsidiaries as of the last day of any fiscal quarter, commencing with the fiscal quarter ending March 31, 2023, and (ii) 2021 Plan Awards that have a grant date at least three (3) years prior to the last day of any fiscal quarter, commencing with the fiscal quarter ending March 31, 2023. The exclusion of Specified Awards from the determination of the maximum aggregate number of shares of our Common Stock available for issuance under the Third Amended and Restated 2021 Plan could have material effect on the number of shares of our Common Stock available for issuance thereunder and could have a material dilutive effect on our stockholders. The Board approved amendments to both the 2021 and 2023 Plans on April 15, 2024. The amendments were subsequently approved by the stockholders at the 2024 Annual Meeting on May 30, 2024. Under the Plans, the number of shares of common stock available for awards is limited to, 18.75 23.75 18.75 23.75 Under the 2023 Plan and 2021 Plan, the Company may grant stock options, restricted stock awards (RSAs) and restricted stock units (RSUs) to executive, management, employees, directors, and certain nonemployee personnel. The awards issued under the Plans can vest immediately, over time or based upon the achievement of market, performance, or service conditions. RSAs and RSUs can vest immediately but generally vest ratably over three years and Performance RSUs generally fully vest after three years, subject to achieving market, service or performance conditions. In addition, the Company recognizes certain Awards held by certain employees and nonemployees that vest upon separation. Each share granted subject to an Award reduces the number of shares available under the 2023 Plan and 2021 Plan by one share. The fair value of stock options is estimated based on the Black-Scholes model, taking into account the historical volatility of our stock, consistent with the accounting guidance. The risk-free interest rate is based on the risk-free zero-coupon rate for a period consistent with the expected option term at the time of grant. The expected option term is calculated based on our historical forfeitures and cancellation rates. During April 2024, the Company cancelled certain vested Awards and modified the terms of certain unvested Awards, to permit different settlement outcomes. The service period and vesting terms were changed at the time of modification. All such vested Awards were fully vested as of the cancellation date and all compensation cost had been recognized. All such unvested equity awards were probable of vesting as of the modification date and the change was accounted for as a Type I modification. In a Type I modification, the Company is required to calculate the incremental difference of the awards, which equals the difference of new award value inclusive of estimated forfeitures and the fair value of the original award as of the modification date. As of the modification date, there is no reversal or adjustment of previously recognized stock compensation expense. Within the 2021 and 2023 Plans, certain master grant agreements were executed on April 15, 2024 that have the potential for future additional grants based on additional stock activity through certain anti-dilution provisions. A mutual understanding of the terms and conditions for the specific awards cannot be obtained until a later date after all stock activity has occurred in the future period and necessary approvals are obtained. When Board approval is obtained and the two grant conditions are met, the grant date will be identified and evidenced through an additional restricted stock agreement. The compensation cost will be recognized per the vesting schedule within the agreement with no catch-up for the reduced period. The accounting impact resulting from the recognition of this equity-based compensation limits the comparability of the Company’s financial statements between periods. During the three months ended September 30, 2024, the Company awarded 542,896 3.96 645,795 3.96 12,844 682,526 of the restricted stock awards vest at separation from the Company, 14,505 of the restricted stock awards vest on June 1, 2025, 14,894 of the restricted stock award vest on June 1, 2026, 1,710 of the restricted stock awards vest on June 1, 2027, and 462,212 of the restricted stock awards vest 33% on September 1, 2025, 33% on September 1, 2026 and 34% on September 1, 2027 During the nine months ended September 30, 2024, the Company awarded 391,544 1.52 90,734 2.41 542,896 3.96 1,892,300 2.50 610,234 1.52 57,255 2.41 645,795 3.96 38,153 of the restricted stock awards vested immediately, 2,704,772 of the restricted stock awards vest at separation from the Company, 690,223 of the restricted stock awards vest 33% on June 1, 2024, 33% on June 1, 2025 and 34% on June 1, 2026, 304,289 of the restricted stock awards vest 33% on June 1, 2025, 33% on June 1, 2026 and 34% on June 1, 2027, 14,505 of the restricted stock awards vest on June 1, 2025, 14,894 of the restricted stock award vest on June 1, 2026, 1,710 of the restricted stock awards vest on June 1, 2027, and 462,212 of the restricted stock awards vest 33% on September 1, 2025, 33% on September 1 , 2026 and 34% on September 1, 2027.

During the nine months ended September 30, 2023, the Company awarded 20,000 7.465 The Company will recognize the compensation expense on a straight-line basis over the service period for the entire Awards. Accordingly, as of September 30, 2024, the Awards from the Plans are presented at fair value within the stockholders’ equity section of the Company’s balance sheet. As of September 30, 2024, unrecognized compensation cost related to unvested Awards was approximately $ 8.8 1.9 On April 15, 2024, a modification related to the cancellation of 48,547 4.0	13.

Stock options are awards that allow holders to purchase shares of the Company’s common stock at a fixed price. Certain options granted may be fully or partially exercisable immediately, may vest on other than a four-year schedule or vest upon attainment of specific performance criteria. Restricted stock awards generally vest one to three years after the date of grant, although certain awards may vest immediately or vest upon attainment of specific performance criteria. Option exercise prices are generally equivalent to the closing market value price of the Company’s common stock on the date of grant. Unexercised options generally terminate ten years after date of grant. The following table presents the weighted-average assumptions used for options granted under the 2021 Plan: Schedule of Weighted Average for Options Granted 2022 Option term (years) 4.95 Volatility 110.21 % Unvested forfeiture rate 0.00 % Risk-free interest rate 3.93 % Dividend yield 0.00 % Weighted-average fair value per option granted $ 14.75 No options were granted under the 2023 Plan, the 2021 Plan, the 2014 Plan and the 2012 Plan for the year ended December 31, 2023. No options were granted under the 2014 Plan and the 2012 Plan for the year ended December 31, 2022. Share-based compensation expense recognized in the Consolidated Statements of Operations is based on awards ultimately expected to vest, therefore, awards are reduced for estimated forfeitures. The accounting standard requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Total share-based compensation expense, related to the Company’s share-based awards, recognized for the years ended December 31, was included within the representative group comprised as follows: Schedule of Share Based Compensation Expense 2023 2022 (Dollars in thousands) Cost of cryptocurrency mining revenue, exclusive of depreciation $ 300 $ 67 Cost of data hosting revenue, exclusive of depreciation 24 - General and administrative expenses, exclusive of depreciation and amortization 3,988 3,785 Share-based compensation expense $ 4,312 $ 3,852 Total unrecognized compensation costs related to non-vested stock options as of December 31, 2023 and December 31, 2022 is approximately $ 266 1.0 0.37 1.36 Presented below is a summary of the Company’s stock option activity for the Plans for the years ended December 31: Summary of Stock Option Activity 2023 2022 Shares under option, beginning 52,393 39,662 Granted - 21,564 Exercised - (7,097 ) Forfeited - (430 ) Expired/canceled - (1,306 ) Shares under option, ending 52,393 52,393 Options exercisable 45,276 38,158 The weighted average exercise price for the Company’s stock option activity for the Plans is as follows for each of the years ended December 31: 2023 2022 Shares under option, beginning $ 102.86 $ 136.00 Granted $ - $ 23.75 Exercised $ - $ 21.50 Forfeited $ - $ 259.75 Expired/canceled $ - $ 196.00 Shares under option, ending $ 102.86 $ 102.86 Options exercisable, ending $ 92.53 $ 78.25 The following table summarizes information for options outstanding and exercisable for the Plans as of December 31, 2023: Summary of Option Outstanding and Exercisable Outstanding Exercisable Weighted Average Weighted Weighted Average Weighted Remaining Average Remaining Average Exercise Price Range Number Contractual Life Exercise Price Number Contractual Life Exercise Price $ 17.50 30.00 25,409 3.88 $ 23.72 25,159 3.85 $ 23.78 $ 30.01 188.00 26,384 4.64 $ 175.11 19,717 4.39 $ 176.50 $ 188.01 277.50 600 7.23 $ 277.50 400 7.23 $ 277.50 52,393 4.30 $ 102.86 45,276 4.12 $ 92.53 The aggregate intrinsic value (i.e., the difference between the closing stock price and the price to be paid by the option holder to exercise the option) is $ 0 0 4.00 Non-vested restricted stock activity is as follows for the year ended December 31: Summary of Non Vested Restricted Stock 2023 2022 Non-vested restricted stock balance, beginning January 1 33,221 16,213 Non-vested restricted stock granted 20,000 29,017 Vested restricted stock — — Non-vested restricted stock exercised (35,336 ) (7,730 ) Non-vested restricted stock forfeited/expired (6,382 ) (4,279 ) Non-vested restricted stock balance, ending December 31 11,503 33,221 The weighted average fair value price for the Company’s restricted stock activity for the Plans is as follows for each of the years ended December 31: Summary of Weighted Average Fair Value Price Restricted Stock Activity 2023 2022 Restricted stock, beginning $ 208.83 $ 282.11 Granted $ 7.47 $ 180.55 Exercised $ 107.84 $ 245.22 Forfeited/ expired $ 112.55 $ 235.54 Restricted stock, ending $ 222.39 $ 208.83 As of December 31, 2023 and 2022, there was approximately $ 1.4 4.8 0.60 2.37 Stock Warrants: The following is a summary of common stock warrant activity during the year ended December 31, 2023.

PROJECT MARIE	17. PROJECT MARIE As previously disclosed in Footnotes 1 and 9, on December 20, 2022, Soluna MC Borrowing 2021-1 LLC (“Borrower”), an indirect wholly owned subsidiary of Soluna Holdings, Inc. (the “Company”), received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG ABL LLC (“NYDIG”) with respect to the Master Equipment Finance Agreement, dated as of December 30, 2021 (the “MEFA”), by and between Borrower and NYDIG. The NYDIG Notice states that (a) Borrower failed to observe or perform certain covenants, conditions or agreements contained in the MEFA and such failure continued unremedied for a period of ten days after Borrower’s knowledge of such breach, which resulted in an event of default under the MEFA, and (b) Borrower defaulted under the guaranty, collateral agreement, or other support agreement, which resulted in an event of default under the MEFA. In addition, the NYDIG Notice states that Borrower failed to pay certain payments of principal and interest under the MEFA when due, which failure also constituted an event of default under the MEFA. As a result of the foregoing events of default, and pursuant to the MEFA, NYDIG (x) declared the principal amount of all loans due and owing under the MEFA and all accompanying Loan Documents (as defined in the MEFA) to be due and immediately payable, (y) imposed a default rate of interest on any outstanding principal amount of each loan (together with all then unpaid interest accruing thereon) and all other obligations under the MEFA and the Loan Documents, and (z) demanded the return of all equipment subject to the MEFA and the Loan Documents. The assets which secure the MEFA represent substantially all of the Company’s mining assets at the site and certain of the operating assets of Project Marie, a 20 MW facility located in Kentucky. The obligations of Borrower under the MEFA and reflected in the NYDIG Notice are ring-fenced to Borrower and its direct parent company, Soluna MC LLC. The Company is not a party to any guaranty, collateral agreement or other support agreement with or for the benefit of NYDIG. For the year ended December 31, 2022, the principal balance of $ 10.5 2.0 3.4 740 251 1.0 9.2 3.4 251 10.3 9.2 1.0 936 On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, which resulted in a reportable disposition of all of the Company’s mining assets at the site and certain of the operating assets of Project Marie. The total net book value of the collateralized assets that were repossessed totaled approximately $ 3.4 With the notice of termination of the Management and Hosting Services from CCMA, the Company notes that this event triggered the impairment of the remaining fixed assets at the Marie facility for the year ended December 31, 2022. Based on the closure of operations on Project Marie, the Company performed an impairment analysis and determined that approximately $ 2.4 For the year ended December 31, 2023, the Company assessed whether the abandonment of the Project Marie facility qualified for the classification of discontinued operations under ASC 205-20-45-1B and 1C. A disposal of a component of an entity or a group of components of an entity shall be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when any of the following occurs: a. The component of an entity or group of components of an entity meets the criteria in paragraph 205-20-45-1E to be classified as held for sale. b. The component of an entity or group of components of an entity is disposed of by sale. c. The component of an entity or group of components of an entity is disposed of other than by sale in accordance with paragraph 360-10-45-15 (for example, by abandonment or in a distribution to owners in a spinoff). As such, the Company deemed that criteria c was applicable as the Project Marie facility was abandoned and ceased further operations beginning on February 23, 2023. However, to qualify for reporting as discontinued operations, it must represent a strategic shift. Per ASC 205-20-45-1C, examples of a strategic shift that has (or will have) a major effect on an entity’s operations and financial results could include a disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity. A strategic shift implies that the disposal must result from a change in the way management had intended to run the business. Management does not believe the closure of Project Marie represented a strategic shift as the Company still fully intends to manage operations through data hosting with customers and proprietary mining arrangements for future pipelines, as such the strategic shift criteria was not met and will not qualify as discontinued operations. However, per ASC 360-10-50-3A, in addition to the disclosures in paragraph 360-10-50-3, if a long-lived asset (disposal group) includes an individually significant component of an entity that either has been disposed of or is classified as held for sale and does not qualify for presentation and disclosure as discontinued operation, a public business entity shall disclose the pretax profit or loss of the individually significant component of an entity for the period in which it is disposed of or is classified as held for sale and for all prior period that are presented in the statement where net income is reported in accordance with ASC 205-20-45-6 through 45-9. Set forth below are the results of Project Marie: Schedule of Results of Project Marie (Dollars in thousands) Year Ended December 31, 2023 Year Ended December 31, 2022 Cryptocurrency mining revenue $ 769 $ 10,028 Data hosting revenue 276 4,131 Total revenue 1,045 14,159 Operating costs: Cost of cryptocurrency mining revenue, exclusive of depreciation 801 6,048 Cost of revenue-depreciation 136 7,813 Data hosting costs 205 3,518 General and administrative expense 379 561 Impairment on fixed assets 43 17,940 Operating loss (519 ) (21,721 ) Interest expense 1,394 1,702 Loss on sale of fixed assets 332 1,623 Other expense, net 1,041 - Net loss before income taxes $ (3,286 ) $ (25,046 )

VARIABLE INTEREST ENTITIES AND VOTING INTEREST ENTITIES	13. VARIABLE INTEREST ENTITIES AND VOTING INTEREST ENTITIES On January 26, 2022, DVSL was created in order to construct, own, operate and maintain variable data centers in order to support the mining of cryptocurrency assets, batch processing and other non-crypto related activities (collectively, the “Project”). On May 3, 2022, SCI entered into a Bilateral Master Contribution Agreement (the “Bilateral Contribution Agreement”) with Spring Lane Capital, pursuant to which Spring Lane agreed, pursuant to the terms and conditions of such agreement, to make one or more capital contributions to, and in exchange for equity in, SCI or one of its subsidiaries up to an aggregate amount of $ 35 On August 5, 2022, the Company entered into a Contribution Agreement (the “Dorothy Contribution Agreement”) with Spring Lane, Soluna DV Devco, LLC (“Devco”), an indirect wholly owned subsidiary of SCI, and DVSL an entity formed in order to further the Company’s development for Project Dorothy, (each, a “Party” and, together, the “Parties”). Pursuant to the Dorothy Contribution Agreement, the Company committed to a capital contribution of up to approximately $ 26.3 4.8 In exchange for their contributions, the Company and Spring Lane were issued 67.8 32.2 100 The Company evaluated this legal entity under ASC 810, Consolidations On March 10, 2023, the Company along with Devco Project Company Purchase and Sale Agreement Spring Lane Dorothy Phase 1A Facility Under a series of transactions in February 2023 and March 2023, culminating in the March 10, 2023 Purchase and Sale Agreement, the Company sold to Spring Lane certain Class B Membership Interests for a purchase price of $ 7.5 Sale 6,790,537 14.6 39,791,988 85.4 5.8 7.5 14.6 67.8 After Spring Lane Capital realizes an 16% Internal Rate of Return hurdle on its investments, the Company retains the right to 50% of the profits on Soluna DVSL ComputeCo. In connection with the Spring Lane transactions and agreements, Soluna DV Services, LLC. will be providing the operations and maintenance services to Soluna DVSL ComputeCo, LLC. Soluna DV Services, LLC expects to receive a margin of 20% for services rendered on certain expenses. Concurrently with the Sale, the Company, Spring Lane, Devco and the Project Company entered into (a) the Fourth Amended and Restated Limited Liability Company Agreement of the Project Company, dated as of March 10, 2023 (the “ Fourth A&R LLCA A&R Contribution Agreement As of January 1, 2023, there were no changes in the Limited Liability Agreement of DVSL other than those related to incorporating the new investment and the purpose and design of DVSL has not changed. The Company evaluated the concepts under ASC 810 for DVSL after the change in membership interest, concluding that this resulted in the Project Company not being structured with non-substantive voting rights, as the noncontrolling shareholders have disproportionately fewer voting rights but the activities are not conducted on their behalf. This, in conjunction with there being sufficient equity at risk to finance its activities and the equity holders as a group having the characteristics of a controlling financial interest in DVSL, results in DVSL not meeting the definition of a VIE. The Company’s consolidation model is based on the concept of power. Given the Company’s Class A membership interest, the Company has the ability to control the significant decisions made in the ordinary course of the business of DVSL. The non-controlling shareholders do not hold substantive participating rights, voting rights or liquidation rights. This results in the Project Company being a voting interest entity (“VOE”), therefore allowing the Company to continue to consolidate. The carrying amount of the assets and liabilities was as follows for DVSL: Schedule of Variable Interest Entities of Assets and Liabilities (Dollars in thousands) September 30, 2024 December 31, 2023 Current assets: Cash and restricted cash $ 3,693 $ 2,275 Accounts receivable, net (allowance for expected credit losses $ 367 0 751 1,201 Other receivable, related party 397 185 Prepaids and other current assets 45 - Total current assets 4,886 3,661 Other assets- long term, related party 2,452 2,172 Operating lease right-of-use assets 85 90 Property, plant, and equipment 12,970 13,712 Total assets $ 20,393 $ 19,635 Current liabilities: Due to intercompany $ 20 $ - Accrued expense 1,509 677 Customer deposits-current 1,410 - Operating lease liability 7 7 Total current liabilities 2,946 684 Operating lease liability 78 83 Current portion of debt Customer deposits- long term - 1,190 Other liabilities, related party 224 224 Total liabilities $ 3,248 $ 2,181 Effective, January 1, 2023, the Company’s ownership in DVSL was reduced from 67.8 14.6 On May 9, 2023, the Company’s indirect subsidiary DVCC completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC , the Company had contributed capital expenditures for the data center. Soluna and Navitas amended and restated the Initial LLCA (the “Existing LLCA”) to reflect Navitas’ contribution of $4.5 million and its receipt of 4,500 Membership Interests, constituting 26.5% of the outstanding Membership Interests of the Company. On June 2, 2023, Soluna and Navitas amended and restated the Existing LLCA to (a) reflect (i) Navitas’s additional capital contribution of approximately $7.6 million and receipt of an additional 7,597 Membership Interests, for a total of 12,097 Membership Interests and 49% ownership of DVCC, and (ii) Soluna’s additional capital contribution of $1.34 million and receipt of an additional 1,340 Membership Interests, for a total of 12,590 Membership Interests and 51% ownership of DVCC, and (b) describe the respective rights and obligations of the Members and the management of DVCC. As of September 30, 2024, Navitas owns 49% and Soluna owns 51% of DVCC. The Company evaluated this legal entity under ASC 810, Consolidations DVCC is a VIE of the Company due to DVCC being structured with non-substantive voting rights. This is due to the following two factors being met as outlined in ASC 810-10-15-14 a. The voting rights of the Company are not proportional to their obligation to absorb the expected losses of the legal entity. The Company gave Navitas veto rights over significant decisions, which results in Soluna having fewer voting rights relative to their obligation to absorb the expected losses of the legal entity. b. Substantially all of DVCC’s activities are conducted on behalf of the Company, which has disproportionally fewer voting rights. Also, the Company is the primary beneficiary due to having the power to direct the activities of DVCC that most significantly impact the performance of DVCC due to its role as the manager handling the day-to-day activities of DVCC as well as majority ownership and the obligation to absorb losses or gains of DVCC that could be significant to the Company. Accordingly, the accounts of DVCC are consolidated in the accompanying financial statements. The carrying amount of the VIE’s assets and liabilities was as follows for DVCC: Schedule of Variable Interest Entities of Assets and Liabilities (Dollars in thousands) September 30, 2024 December 31, 2023 Current assets: Cash and restricted cash $ 1,841 $ 2,575 Accounts receivable 31 217 Prepaids and other current assets 63 - Other receivable, related party 449 476 Total current assets 2,384 3,268 Other assets- long term, related party 2,452 2,172 Operating lease right-of-use assets 85 90 Property, plant, and equipment, net 18,735 22,188 Total assets $ 23,656 $ 27,718 Current liabilities: Due to intercompany $ 1,107 $ 1,259 Accrued expense 1,359 2,213 Operating lease liability 7 7 Current portion of debt 291 1,682 Total current liabilities 2,764 5,161 Operating lease liability 78 83 Total liabilities $ 2,842 $ 5,244 On July 22, 2024 (the “Effective Date”), Soluna Holdings, Inc. (the “Company”) closed financing for the Dorothy 2 project. This project involves Soluna Digital, Inc. (the “Developer”) and Soluna DVSL II ComputeCo, LLC (the “ComputeCo”), a special purpose vehicle initially owned solely by the Developer. They are collaborating on the development, design, procurement, and construction of a 48 MW modular data center (the “Project Dorothy 2”) in Briscoe County, TX. This facility, located in Silverton, Texas, is owned by ComputeCo and operated by Soluna US Services, LLC, and may engage in cryptocurrency, batch processing, and other non-crypto related activities. It is adjacent to two other Company modular data center projects at the same site. Project Dorothy 2 is financed by Soluna2 SLC Fund II Project Holdco LLC, an investment vehicle of Spring Lane Capital (“SLC”) with a capital contribution of up to $ 29.98 4.6 Project Dorothy 2 allows the Developer to invest in ComputeCo, with the total ownership of the Developer and its affiliates capped at 49 This investment can occur within 30 days after the Effective Date (treated equally to the initial Investor), from day 31 to 180 days after the Effective Date (subject to a purchase price formula with a 20% discount rate), or after 180 days with the initial Investor’s approval On May 16, 2024, the Company secured $ 1.0 million in financing from SLC for equipment and machinery for Project Dorothy 2 through an Equipment Loan Agreement (the “ELA”) between SDI SL Borrowing - 1, LLC (the “Borrower”) and SLC. On that date, SLC lent the Borrower $ 720,000 to purchase medium voltage cables and low voltage switchboards. This debt was later assigned to ComputeCo on the Effective Date. Subsequently, the Borrowing amount in full by issuing the Investor Class B Membership Interests in the Dorothy 2 project valued at three times the borrowing amount (i.e., $2.16 million). The Company evaluated this legal entity under ASC 810, Consolidations The carrying amount of the assets and liabilities was as follows for ComputeCo: Schedule of Variable Interest Entities of Assets and Liabilities (Dollars in thousands) September 30, 2024 Current assets: Cash and restricted cash $ 290 Accounts receivable, intercompany 2,855 Other receivable, related party 1,378 Total current assets 4,523 Other assets- long term, related party 4,028 Total assets $ 8,551 Current liabilities: Accounts payable, trade $ 28 Accounts payable, related party 738 Due to intercompany 3 Total current liabilities 769 Total liabilities $ 769	18. VARIABLE INTEREST ENTITY VARIABLE INTEREST ENTITIES AND VOTING INTEREST ENTITIES On January 26, 2022, DVSL was created in order to construct, own, operate and maintain variable data centers in order to support the mining of cryptocurrency assets, batch processing and other non-crypto related activities (collectively, the “Project”). On May 3, 2022, SCI entered into a Bilateral Master Contribution Agreement (the “Bilateral Contribution Agreement”) with Spring Lane Capital, pursuant to which Spring Lane agreed, pursuant to the terms and conditions of such agreement, to make one or more capital contributions to, and in exchange for equity in, SCI or one of its subsidiaries up to an aggregate amount of $ 35 On August 5, 2022, the Company entered into a Contribution Agreement (the “Dorothy Contribution Agreement”) with Spring Lane, Soluna DV Devco, LLC (“Devco”), an indirect wholly-owned subsidiary of SCI, and DVSL an entity formed in order to further the Company’s development for Project Dorothy, (each, a “Party” and, together, the “Parties”).

The Company evaluated the power and benefits concepts under ASC 810 to determine whether the change in investment of Class B memberships would change the consolidation of the DVSL, and the Company concluded that, after the additional investment by Spring Lane, Soluna continues to have a controlling financial interest in DVSL. In addition, the Company continues to have the power and benefits associated with DVSL and therefore will continue to consolidate.

Correction of an Error	Correction of an Error While preparing the Company’s Form 10-K for the year ended December 31, 2023, the Company identified the following errors related to the presentation of basic and diluted Earnings Per Share (“EPS”) in its historical filing for the year ended December 31, 2022, and for the quarters ended March 31, 2023, June 30, 2023, and September 30, 2023: ● Inclusion of the net income/loss from noncontrolling interest in the numerator; ● Inclusion of the cumulative undeclared preferred dividends in the numerator; ● Exclusion of shares issued for little or no cash consideration (ie: penny warrants) in the denominator. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements;” the Company evaluated the errors and has determined that the related impacts were not material to any prior annual or 10-Q report, but that correcting the cumulative impact of such errors would be significant to our EPS for the year ended December 31, 2023. Accordingly, the Company has corrected such immaterial errors by adjusting its December 31, 2022 consolidated statement of operations related to the calculation of earnings per share. The Company also corrected previously reported interim financial information for such immaterial errors in future filings, as applicable. The following summarizes the effect of the revision on each financial statement line item.

Use of Estimates		Use of Estimates The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Property, Plant, and Equipment		Property, Plant, and Equipment Property, plant and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives as follows: Schedule of Property Plant and Equipment Estimated Useful Lives Leasehold improvements Lesser of the life of the lease or the useful life of the improvement Computers and related software 3 5 Cryptocurrency miners 3 Machinery and equipment 8 15 Office furniture, equipment and fixtures 2 10 Buildings 30 40 Purchased pre-fabricated buildings 15 20 Significant additions or improvements extending assets’ useful lives are capitalized; normal maintenance and repair costs are expensed as incurred. The costs of fully depreciated assets remaining in use are included in the respective asset and accumulated depreciation accounts. When items are sold or retired, related gains or losses are included in net (loss) income.
Intangible assets		Intangible assets Intangible assets include the Strategic Pipeline Contract with an estimated useful life of 5 5 15 25
Income Taxes		Income Taxes The Company is subject to income taxes in the U.S. (federal and state). As part of the process of preparing our consolidated financial statements, the Company calculates income taxes for each of the jurisdictions in which the Company operates. This involves estimating actual current taxes due together with assessing temporary differences resulting from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities, loss carryforwards and tax credit carryforwards, for which income tax benefits are expected to be realized in future years. A valuation allowance has been established to reduce deferred tax assets, if it is more likely than not that all, or some portion, of such deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. Significant management judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against the Company’s net deferred tax assets. The Company considers all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income amongst other items in determining the Company’s valuation allowance. In addition, the Company’s assessment requires the Company to schedule future taxable income in accordance with accounting standards that address income taxes to assess the appropriateness of a valuation allowance, which further requires the exercise of significant management judgment. The Company accounts for taxes in accordance with the asset and liability method of accounting for income taxes. Under this method, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution The Company is currently subject to audit in various jurisdictions, and these jurisdictions may assess additional income tax liabilities against us. Developments in an audit, litigation, or in applicable laws, regulations, administrative practices, principles, and interpretations could have a material effect on the Company’s operating results or cash flows in the period or periods in which such developments occur, as well as for prior and in subsequent periods. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating the Company’s provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. The Company’s effective tax rates could be affected by numerous factors, such as intercompany transactions, earnings being lower than anticipated in jurisdictions where the Company has lower statutory rates and higher than anticipated in jurisdictions where the Company has higher statutory rates, the applicability of special tax regimes, losses incurred in jurisdictions for which the Company is not able to realize the related tax benefit, changes in foreign currency exchange rates, entry into new businesses and geographies, changes to its existing businesses and operations, acquisitions and investments and how they are financed, changes in the Company’s stock price, changes in its deferred tax assets and liabilities and their valuation, and changes in the relevant tax, accounting, and other laws, regulations, administrative practices, principles, and interpretations.

Equity Investments without Readily Determinable Fair Values		Equity Investments without Readily Determinable Fair Values Our equity investment in HEL is accounted for under the measurement alternative. Equity securities measured and recorded using the measurement alternative are recorded at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes. Adjustments resulting from impairments and observable price changes are recorded in the income statement. There was an impairment recognized for the full amount of $ 750
Equity Method Investments		Equity Method Investments The Company’s consolidated net income or loss will include our proportionate share, if any, of the net income or loss of our equity method investee. When the Company records its proportionate share of net income, it increases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. Conversely, when the Company records its proportionate share of a net loss, it decreases equity income (loss), net in our consolidated statements of operations and our carrying value in that investment. When the Company’s carrying value in an equity method investee company has been reduced to zero, no further losses are recorded in the Company’s financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding. When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized. As of December 31, 2023, the Company owned approximately 47.5 75,049,937 240,000,000 0
Variable Interest Entities		Variable Interest Entities Variable Interest Entities (“VIEs”) are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the entity’s expected losses, or the right to receive the entity’s expected residual returns. The Company consolidates a VIE when it is the primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) through its interests in the VIE, the obligation to absorb expected losses or the right to receive expected benefits from the VIE that could potentially be significant to the VIE. The Company consolidates the accounts of Soluna DVSL ComputeCo, LLC (“DVSL”) and Soluna DV ComputeCo, LLC (“DVCC”), each a VIE. The Company held a 67.8 14.6 100 51
Non-Controlling Interests		Non-Controlling Interests The ownership interest held by owners other than the Company in less than wholly-owned subsidiaries are classified as non-controlling interests. The value attributable to the non-controlling interests is presented on the consolidated balance sheets separately from the equity attributable to the Company. Net income (loss) attributable to non-controlling interests are presented separately on the consolidated statements of operations and consolidated statements of comprehensive income, respectively.
Fair Value Measurement		Fair Value Measurement The estimated fair value of certain financial instruments, including cash, accounts receivable and short-term debt approximates their carrying value due to their short maturities and varying interest rates. “Fair value” is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation methods, the Company is required to provide the following information according to the fair value accounting standards. These standards established a fair value hierarchy as specified that ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities are classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities, which includes listed equities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. These items are typically priced using models or other valuation techniques. These models are primarily financial industry-standard models that consider various assumptions, including the time value of money, yield curves, volatility factors, as well as other relevant economic measures. Level 3: These use unobservable inputs that are not corroborated by market data. These values are generally estimated based upon methodologies utilizing significant inputs that are generally less observable from objective sources. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. On October 25, 2021, pursuant to a securities purchase agreement dated October 20, 2021 (the “SPA), the Company issued to certain accredited investors Class A, Class B and Class C common stock purchase warrants (collectively, the “Warrants”) to purchase up to an aggregate of 71,043 312.50 375 450 As noted in Note 9, the Company entered into an Addendum and Addendum Amendment in which the Company surrendered their Class B and Class C warrants in July and September 2022, in exchange for Class D common stock purchase warrants at an exercise price of $ 87.50 112.50 137.50 187.50 56.00 54.50 53.25 52.00 240,000 12.50 80,000 20.00 4.20 4.03 Any modifications of the warrants were subsequently revalued, including the warrants attached to the Third Amendment on November 20, 2023, see Note 9 for details. Inherent in a Black-Scholes simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from its traded warrants and historical volatility of select peers’ common stock with a similar expected term of the Warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield on the grant date with a maturity similar to the expected remaining term of the warrants. The expected term of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company expects to remain at zero. The warrants were collectively classified as a Level 3 measurement within the fair value hierarchy because these valuation models involve the use of unobservable inputs relating to the Company’s estimate of its expected stock volatility which was developed based on the historical volatility of a publicly traded set of peer companies. The following table represents the significant fair value assumptions used for warrants issued or repriced during the years ended December 31, 2023 and 2022: Schedule of Fair Value Assumptions For Warrants Issued 2023 2022 Stock price (1) $ 2.93 5.00 $ 14.25 259.25 Exercise price (1) $ 0.01 20.00 $ 19.00 331.50 Expected term in years 1.16 5.00 2.00 5.00 Expected dividend yield 0.00 % 0.00 % Volatility 108.50 140 % 125 150 % Risk-free interest rate 3.36 5.25 % 1.18 4.41 % (1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for- 25 Following the debt extinguishment on July 19, 2022 as noted further in Note 9, the Convertible Notes will be accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. The Company had a subsequent Addendum Amendment on September 13, 2022, a Second Amendment on May 11, 2023, and a Third Amendment on November 20, 2023, which each caused a revaluation of the fair value on the executed Addendum Amendment, Second Amendment, and Third Amendment date. Although the Notes are not being accounted for under 825-10, the substance of the debt is considered to be the same and is therefore considered outside the scope of ASC 470-60. As such, the Company performed a fair value analysis of the Convertible Notes. For the year-ended December 31, 2022 and 2023, the Company had Monte Carlo simulations run-out for the expected conversion dates of the Convertible Notes using risk free rates, annual volatility, daily trading volumes, likely conversion profiles, and other assumptions based on principal and accrued interest as of the year-end. The Company determined the fair value of the Convertible Notes uses certain Level 3 inputs. The following table represents the significant and subjective fair value assumptions used for Convertible Notes during the years ended December 31, 2023 and 2022: Schedule of Fair Value Assumptions For Convertible Notes 2023 2022 Stock price (1) $ 3.60 6.75 $ 6.5 Conversion price (1) $ 3.78 7.99 $ 7.99 Volatility 87.50 150 % 65 105 % Risk-free interest rate 4.64 5.50 % 4.12 4.76 % (1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for- 25 Changes in Level 3 Financial Liabilities Carried at Fair Value Schedule of Changes in Level 3 Financial Liabilities Carried at Fair Value (in thousands) Balance, July 19, 2022 (date of Addendum of convertible notes) $ 14,610 Conversions of debt (1,100 ) Total revaluation loss 597 Balance, September 13, 2022 14,107 Total revaluation gains (1,853 ) Balance, December 31, 2022 $ 12,254 Conversions of debt (January 2023- May 11 2023) (1,344 ) Total revaluation losses 30 Balance, May 11, 2023 (date of Second Amendment) 10,940 Conversions of Debt (May 11, 2023-November 19, 2023) (1,550 ) Total revaluation losses 1,569 Balance November 20, 2023 (date of Third Amendment) $ 10,959 Financial liabilities , Beginning balance $ 10,959 Conversions of debt (November 20, 2023- December 31, 2023) (3,069 ) Conversions of debt (3,069 ) Total revaluation losses 584 Total revaluation (gains) losses 584 Balance December 31, 2023 $ 8,474 Financial liabilities, Ending balance $ 8,474 Consistent with the guidance in purchase accounting, the value of the pipeline of certain cryptocurrency mining projects previously owned by HEL acquired in the Soluna Callisto acquisition in October 2021 as of the acquisition date was estimated using an expected value approach, which probability-weights various future outcomes and uses certain Level 3 inputs. Included in those inputs are the following key assumptions: expected growth in share price at a risk-free rate in the risk-neutral framework based on U.S. Treasury Rates as of the valuation date, volatility of share price based on historical equity volatilities of comparable companies over a lookback period, assessments associated with qualified projects based on assessment on timing of payments and assessment of active megawatt scenarios and the associated probabilities. The resulting amounts are then discounted to present value through use of a discount rate that considers, among other things, the risk of the payments, credit risk of the Company, and overall weighted average cost of capital of the acquired business. The resulting calculations resulted in an estimated fair value of the acquired assets and consideration paid in common stock of approximately $ 33 3.5
Revenue Recognition		Revenue Recognition Cryptocurrency Mining Revenue The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principles of the revenue standard are that a company should recognize revenue to depict the transfer of promised good or services to customers in an amount that reflects the consideration to which the company expects to be entitled for those goods or services. The following five steps are applied to achieve that core principle: ● Step 1: Identify the contract with the 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 the Company satisfies a performance obligation In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract). If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct. The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following: ● Variable consideration ● Constraining estimates of variable consideration ● The existence of a significant financing component in the contract ● Noncash consideration ● Consideration payable to a customer Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time. Providing computing power to solve complex cryptographic algorithms in support of the Bitcoin blockchain (in a process known as “solving a block”) is an output of the Company’s ordinary activities. The provision of providing such computing power is the only performance obligation in the Company’s contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block (by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue is recognized. There is no significant financing component in these transactions. Fair value of the cryptocurrency award received is determined using the quoted price of the related cryptocurrency where the Company is registered at the time of receipt. The mined cryptocurrency is immediately paid to the Coinbase and Bittrex wallet. Cryptocurrency is converted to U.S. dollars nearly everyday, as SCI is not in the business of accumulating material amounts of cryptocurrency on its balance sheet. Data center hosting The Company has entered customer hosting contracts whereby the Company provides electrical power and network connectivity to cryptocurrency mining customers, and the customers pay a stated amount per megawatt-hour (“MWh”) (“Contract Capacity”), a fixed rate, as well as a percentage of the profit share of net income from the customer’s mining operations. The actual monthly amounts are calculated after the close of each month and billed the customer. If any shortfalls due to outages are experienced, service level credits may be made to customers to offset outages which prevented them from cryptocurrency mining. Customer contract security deposits are reflected as other liabilities and are made at the time the contract is signed and held until the conclusion of the contract relationship Deferred revenue is primarily from advance monthly payments received and revenue is recognized when service is completed. Demand Response Service The Company provides emergency demand response solutions to ERCOT pursuant to a contractual commitment over defined service delivery periods. This contract includes a single promise to stand ready, on a monthly basis, to deliver a set amount of curtailment (committed capacity) per month when and if called upon by ERCOT. The Company has concluded this represents a series of distinct monthly services that are substantially the same, with the same pattern of transfer to the customer. Accordingly, the monthly promise to stand ready is accounted for as a single performance obligation. The Company is the principal in these arrangements as it has control over the services prior to those services being transferred to the customer. Capacity fees are paid to the Company by ERCOT for its stand ready commitment to curtail MWs and are typically based on the Company’s ability to deliver the committed capacity throughout the contractual delivery period. In general, if the Company fails to curtail the contracted MW during energy or emergency dispatches, the MW shortfall results in a penalty that could require the Company to reduce the fees paid by the customer during the contract period. In order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. These estimates consider i) the contractual rate per MW, and ii) historical performance. The Company constrains (reduces) the estimates of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required. In the event of an emergency dispatch, any earned energy fees are associated and allocated to the specific month of performance, as these fees meet the criteria to allocate variable consideration to a distinct monthly service within a series of distinct services that comprise the single performance obligation. Therefore, energy fees are recognized in the month in which the Company is called upon to deliver on its stand-ready obligation to curtail capacity. The Company believes that an output measure based on the monthly contractual MW stand-ready obligation is the best representation of the “transfer of value” to the customer. Accordingly, the Company recognizes monthly revenue based on the proportion of committed stand-ready capacity obligation that has been fulfilled to date.
Cost of Cryptocurrency Mining and Data Center Hosting Revenue		Cost of Cryptocurrency Mining and Data Center Hosting Revenue Cost of cryptocurrency mining and data center hosting revenue includes direct utility costs as well as overhead costs that relate to the operations of SCI’s cryptocurrency mining facility.
Accounts Receivable and Allowance		Accounts Receivable and Allowance The Company’s accounts receivable balance consists of amounts due from its data center hosting customers and receivables for demand response services. The Company records accounts receivable at the invoiced amount less an allowance for any potentially uncollectable accounts under the current expected credit loss (“CECL”) impairment model and presents the net amount of the financial instrument expected to be collected. The CECL impairment model requires an estimate of expected credit losses, measured over the contractual life of an instrument, that considers forecasts of future economic conditions in addition to information about past events and current conditions. Based on this model, the Company considers many factors, including the age of the balance, collection history, and current economic trends. The Company determines the allowance based on historical write-off experience and current exposures identified. The Company reviews its allowance for potentially uncollectible accounts under CECL monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered. The Company does not have any off balance-sheet credit exposure related to its customers. Bad debts are written off after all collection efforts have ceased. Allowances for credit losses are recorded as a direct reduction from an asset’s amortized cost basis. Credit losses and recoveries are recorded in G eneral and administrative expenses
Notes Receivable		Notes Receivable The Company’s notes receivable consists of loans made by the Company, who serves as the debt holder, to different entities, serving as borrowers. The Company accounts for its notes receivable in accordance with ASC Topic 310, Receivables (“ASC 310”). In accordance with ASC 310, notes receivable are reported on the balance sheet at their amortized cost basis. The amortized cost basis is the amount at which a financing receivable or investment is originated or acquired, adjusted for applicable accrued interest, accretion, or amortization of premium, discount, and net deferred fees or costs, or other adjustments. The Company’s notes receivable were all issued at their respective principal amounts. Interest income will be recognized based on the contractual rate in the loan agreement and any premium/discount will be amortized to interest income using the effective interest rate method. The Company does not currently maintain a loan loss allowance as it has not experienced any such losses in historical periods and does not anticipate future losses. The Company evaluates any potential need for loan loss reserves on a periodic basis based on relevant internal and external factors that affect loan collectability, including the amount of outstanding loans owed to the Company, current collection patterns and current economic trends. As these conditions change, the Company may need to record allowances in future periods.
Employee Receivables		Employee Receivables Certain employees have a receivable due to the Company based on their stock-based awards, in which $ 110 120 13 26 97 94
Deposits and Credits on equipment	Deposits and Credits on equipment As of September 30, 2024 and December 31, 2023, the Company had approximately $ 5.0 1.0 975 49 926	Deposits and Credits on equipment As of December 31, 2023 and December 31, 2022, the Company had approximately $ 1.0 1.2 975
Warrant Liability	Warrant Liability Under the guidance in ASC 815, Derivatives and Hedging As discussed in Footnote 7, on June 20, 2024, Soluna AL Cloudco, LLC (“CloudCo”), a subsidiary of Soluna Cloud, Inc (“Cloud”), entered into a Promissory Note Agreement of $ 12.5 1.25 0	Warrant Liability
Long-Lived Assets		Long-Lived Assets The Company accounts for impairment or disposal of long-lived assets, which include property, plant, and equipment and also finite-lived intangible assets, in accordance with accounting standards that address the financial accounting and reporting for the impairment or disposal of long-lived assets, specify how impairment will be measured, and how impaired assets will be classified in the consolidated financial statements. On a quarterly basis, the Company analyzes the status of its long-lived assets at each subsidiary for potential impairment. Recoverability of assets to be held and used are measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. Because the impairment test for long-lived assets held in use is based on estimated undiscounted cash flows, there may be instances where an asset or asset group is not considered impaired, even when its fair value may be less than its carrying value, because the asset or asset group is recoverable based on the cash flows to be generated over the estimated life of the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. During the year ended December 31, 2023 and 2022, the Company has impaired approximately $ 575 47.4 no
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months.	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months.
Restricted Cash	Restricted Cash Restricted cash relates to cash that is legally restricted as to withdrawal and usage or is being held for a specific purpose and thus not available to the Company for immediate or general business use. As of September 30, 2024, the Company had restricted cash of approximately $ 3.4 2.0 1.46 4.0 3.0 1.0	Restricted Cash Restricted cash relates to cash that is legally restricted as to withdrawal and usage or is being held for a specific purpose and thus not available to the Company for immediate or general business use. As of December 31, 2023, the Company had restricted cash of approximately $ 4.0 3.0 1.0 685
Net (loss) Income per Share		Net (loss) Income per Share The Company computes basic income per common share by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted income per share reflects the potential dilution, if any, computed by dividing income by the combination of dilutive common share equivalents, comprised of shares issuable under outstanding investment rights, warrants and the Company’s share-based compensation plans, and the weighted average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money stock options, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of a stock option and the amount of compensation cost, if any, for future service that the Company has not yet recognized are assumed to be used to repurchase shares in the current period.
Share-Based Payments		Share-Based Payments The Company grants options to purchase our common stock and awards restricted stock to our employees and directors under our equity incentive plans. The benefits provided under these plans are share-based payments and the Company accounts for stock-based awards exchanged for employee service in accordance with the appropriate share-based payment accounting guidance. Stock-based compensation represents the cost related to stock-based awards granted to employees and directors. The Company measures stock-based compensation cost at grant date based on the estimated fair value of the award and recognizes the cost as expense on a straight-line basis in accordance with the vesting of the options (net of estimated forfeitures) over the option’s requisite service period. The Company estimates the fair value of stock-based awards on the grant date using a Black-Scholes valuation model. The Company uses the fair value method of accounting with the modified prospective application, which provides for certain changes to the method for valuing share-based compensation. The valuation provisions apply to new awards and to awards that are outstanding on the effective date and subsequently modified. Under the modified prospective application, prior periods are not revised for comparative purposes. Stock-based compensation expense is recorded in the lines titled “Cost of cryptocurrency mining revenue,” “Cost of data hosting revenue,” and “Selling, general and administrative expenses” in the Consolidated Statements of Operations based on the employees’ respective functions. The Company records deferred tax assets for awards that potentially can result in deductions on the Company’s income tax returns based on the amount of compensation cost that would be recognized upon issuance of the award and the Company’s statutory tax rate. All income tax effects of awards, including excess tax benefits, recognized on stock-based compensation expense are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes on a prospective basis. The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the Company’s expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate, and expected dividends. Theoretical valuation models and market-based methods are evolving and may result in lower or higher fair value estimates for share-based compensation. The timing, readiness, adoption, general acceptance, reliability, and testing of these methods is uncertain. Sophisticated mathematical models may require voluminous historical information, modeling expertise, financial analyses, correlation analyses, integrated software and databases, consulting fees, customization, and testing for adequacy of internal controls. For purposes of estimating the fair value of stock options granted using the Black-Scholes model, the Company uses the historical volatility of its stock for the expected volatility assumption input to the Black-Scholes model, consistent with the accounting guidance. The risk-free interest rate is based on the risk-free zero-coupon rate for a period consistent with the expected option term at the time of grant. The expected option term is calculated based on our historical forfeitures and cancellation rates. The fair value of restricted stock awards is based on the market close price per share on the grant date. The Company expenses the compensation cost of these awards as the restriction period lapses, which is typically a one- to three-year service period to the Company. The shares represented by restricted stock awards are outstanding at the grant date, and the recipients are entitled to voting rights with respect to such shares upon issuance.
Notes payable		Notes payable The Company records notes payable net of any discount or premiums. Discounts and premiums are amortized as interest expense or income over the life of the note in such a way as to result in a constant rate of interest when applied to the amount outstanding at the beginning of any given period.
Concentration of Credit Risk		Concentration of Credit Risk Financial instruments that subject the Company to concentrations of credit risk principally consist of cash equivalents and trade accounts receivable. The Company’s trade accounts receivable are from data hosting revenue with the Company’s customers throughout the year. The Company does not require collateral and has not historically experienced significant credit losses related to receivables from individual customers or groups of customers in any particular industry or geographic area. The Company requires that hosting customers make a prepayment of the next month’s estimated expenses or make a security deposit to the Company. The Company has cash deposits in excess of federally insured limits but does not believe them to be at risk.
Other Comprehensive Income		Other Comprehensive Income The Company had no other comprehensive income items for the years ended December 31, 2023 and 2022.
Leases		Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liability on our consolidated balance sheets. The Company did not have any finance leases as of December 31, 2023 or December 31, 2022. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU assets also include any lease payments made and excludes lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend or terminate its leases when it is reasonably certain that the Company will exercise those options. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, the Company accounts for lease components together with non-lease components (e.g., common-area maintenance).
Accounting Updates Effective for fiscal year 2023		Accounting Updates Effective for fiscal year 2023 Changes to U.S. GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standard updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considered the applicability and impact of all ASUs. ASUs not mentioned below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. In June 2016, the FASB issued ASU 2016-13 (Financial Instruments - Credit Losses (Topic 326)) and its subsequent amendments to the initial guidance within ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, ASU 2019-11 and ASU 2020-02, respectively (collectively, Topic 326). Topic 326 changes how entities will measure credit losses for most financial assets and certain other instruments that are not accounted for at fair value through net income. This standard replaces the existing incurred credit loss model and establishes a single credit loss framework based on a current expected credit loss model for financial assets carried at amortized cost, including loans and held-to- maturity debt securities. The current expected loss model requires an entity to estimate credit losses expected over the life of the credit exposure upon initial recognition of that exposure when the financial asset is originated or acquired, which will generally result in earlier recognition of credit losses. This standard also requires expanded credit quality disclosures. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. This standard also simplifies the accounting model for purchased credit-impaired debt securities and loans. This standard will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. ASU 2018-19 clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASU 2019-04 clarifies that equity instruments without readily determinable fair values for which an entity has elected the measurement alternative should be remeasured to fair value as of the date that an observable transaction occurred. ASU 2019-05 provides an option to irrevocably elect to measure certain individual financial assets at fair value instead of amortized cost. This standard should be applied on either a prospective transition or modified-retrospective approach depending on the subtopic. This standard will be effective for the Company for annual and interim reporting periods beginning on or after December 15, 2022, and while early adoption is permitted, the Company does not expect to elect that option. This standard has been adopted as of January 1, 2023, and did not have any material impact for the Company’s operations. The Company will continue to evaluate if any changes occur subsequently and properly record and disclose in relation to Topic 326.

Additionally, the First Reconcile Date was extended to October 12, 2022. The Company gave notice to the Noteholders on October 10, 2022 that the Company would be conducting an equity financing. This in turn paused the commencement of (a) the Second Conversion and the Second Reconcile Date, and (b) the Third Conversion and the Third Reconcile Date, in each case, for forty-five (45) Trading Days, each as defined in the Addendum. This also had the effect of pausing the Company’s requirement to make the Third Deposit of $1,000,000 under the October Purchase Agreement as amended by the Addendum, for 45 Trading Days. The 45-day trading window opened on December 20, 2022 to allow the Noteholders to apply the 20% discount to the 5-day VWAP of the Company’s stock.
