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, “SCI” refers to Soluna Computing, Inc., formerly known as EcoChain, Inc., and “MTI Instruments” refers to MTI Instruments, Inc. SHI currently conducts our business through our wholly-owned subsidiary, SCI. SCI is engaged in the mining of cryptocurrency through data centers that can be powered by renewable energy sources. Recently, SCI has built, and intends to continue to develop and build, modular data centers that are used for cryptocurrency mining and that in the future can be used for computing intensive, batchable applications, such as artificial intelligence and machine learning, with the goal of providing a cost-effective alternative to battery storage or transmission lines. Headquartered in Albany, New York, the Company uses technology and intentional design to solve complex, real-world challenges. SCI incorporated in Delaware on January 8, 2020 as EcoChain, Inc., which operates a cryptocurrency mining facility that integrates with the cryptocurrency blockchain network in the State of Washington. Through the October 2021 acquisition by EcoChain, Inc. of an entity at the time named Soluna Computing, Inc., SCI also has a pipeline of certain cryptocurrency mining projects previously owned by Harmattan Energy, Ltd. (“HEL”) (formerly known as Soluna Technologies, Ltd.), a Canadian corporation incorporated under the laws of the Province of British Colombia that develops vertically-integrated, utility-scale computing facilities focused on cryptocurrency mining and cutting-edge blockchain applications. Following such acquisition, on November 15, 2021, SCI completed its conversion and redomicile to Nevada and changed its name from “EcoChain, Inc.” to “Soluna Computing, Inc.”. The following day, the acquired entity, Soluna Computing, Inc., changed its name to “Soluna Callisto Holdings Inc.” (“Soluna Callisto”). Until the April 11, 2022 sale described 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 consist 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 are 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% of the issued and outstanding common stock of MTI Instruments (the “Sale”). As a result of the foregoing, the MTI Instruments business was reported as discontinued operations in our consolidated financial statements as of December 31, 2021 and prior periods included in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 31, 2022 (our “Annual Report”), as well as in these consolidated financial statements as of June 30, 2022 and prior periods. On April 11, 2022, we consummated the Sale, MTI Instruments ceased to be our wholly-owned subsidiary and, as a result, we have exited the instruments business. See Note 14 for additional information on the Sale. 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.” 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 $9.25 million in cash, subject to certain adjustments as set forth in the Stock Purchase Agreement (the “Sale”). The consideration paid by the Purchaser to the Company was based on an aggregate enterprise value of approximately $10.75 million. The Company recognized a gain on sale of approximately $7.6 million. Going Concern and Liquidity The Company’s financial statements as of June 30, 2022 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 financial statements, the Company did not generate sufficient revenue to generate net income, and has negative working capital These factors, among others indicate that there is The ability to continue as a going conce rn 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 issuance, project level equity, debt borrowings, partnerships and/or collaborations. In addition, as discussed above and further in Notes 14, and 15, the Company sold the MTI Instruments business in April 2022 to focus on developing and monetizing green, zero-carbon computing and cryptocurrency mining facilities. The Company received approximately $ 9.0 0.2 million Following June 30, 2022, to further implement management’s strategy, the Company entered into various transactions as further described in Note 17 to recapitalize and negotiate revised terms with senior secured lenders, which released collateral (thus enabling execution of the project financing strategy) and to provide a means for holders of the secured obligations to reduce their debt through the equity markets, including entering into the Addendum (as defined in Note 17) to allow the Company to convert $3.3 million in notes payable to common stock and redeem up to $6.6 million of notes payable, the issuance and sale of $5.0 million in a new series of preferred stock. In addition, also as further described in Note 17, in May 2022, entered into a structural understanding with Soluna to provide up to $35.0 million in project financing subject to various milestones and conditions precedent and following the recapitalization and restructuring discussed above, in August 2022, the Company entered into an agreement with Spring Lane for an initial funding of up to $12.5 million of the up to $35.0 million commitment for . Management will continue to evaluate different strategies to obtain financing to fund operations, but believes that these transactions, and the availability of up to $7.1 million in additional equipment financing with a third party lender, together with the Company’s cash on hand of approximately $4.6 million as of June 30, 2022 and proceeds from potential capital raising activities and/or increasing the available under our credit facilities, will allow the Company to meet its outstanding commitments relating to capital expenditures as of June 30, 2022 of $1.5 million and other operational needs. H The COVID-19 global pandemic has been unprecedented and unpredictable and the impact is likely to continue to result in significant national and global economic disruption, which may adversely affect our business. Although the Company has experienced some minor changes to our miner shipments due to disruptions in the global supply chain, the Company does not expect any material impact on our long-term strategic plans, our operations, or our liquidity due to the impacts of COVID-19. arious macroeconomic factors could adversely affect our business and the results of our operations and financial condition, including changes in inflation, interest rates and overall economic conditions. For instance, inflation could negatively impact the Company by increasing our labor costs, through higher wages and higher interest rates. If inflation or other factors were to significantly increase our business costs, our ability to develop our current projects may be negatively affected. Interest rates, the liquidity of the credit markets and the volatility of the capital markets could also affect the operation of our business and our ability to raise capital in order to fund our operations. However, the Company is actively monitoring this situation and the possible effects on our financial condition, liquidity, operations, suppliers, and the industry.

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 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 our Annual Report. The information presented in the accompanying condensed consolidated balance sheet as of December 31, 2021 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 six months ended June 30, 2022 and June 30, 2021. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and our wholly-owned subsidiary, SCI, as of June 30, 2022 and for the three and six months ended June 30, 2022 and 2021, also includes the accounts of our then wholly-owned subsidiary, MTI Instruments. All intercompany balances and transactions are eliminated in consolidation. Change in Par Value Unless otherwise noted, all capital values, share and per share amounts in the condensed consolidated financial statements have been retroactively restated for the effects of the Company’s change in par value from $0.01 to $0.001, which became effective after the redomestication to the State of Nevada on March 29, 2021. 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. The reclassifications relate to the presentation of discontinued operations and a correction of an error. Correction of an Error The Company recorded cash preferred dividend distributions of $630 thousand in the Annual Report presentation as an increase within accumulated deficit. However, in the absence of retained earnings, cash dividends should generally be charged to Additional-Paid-in Capital (“APIC”). This treatment is supported by Accounting Standards Codification (“ASC”) 480-10-S99-2, which requires accretion of redeemable preferred stock to be charged to APIC in the absence of retained earnings. As the Company did not have accumulated profit (i.e.: absence of retained earnings), the preferred cash dividends should have been charged to APIC. The following tables present the effects of the correction of the prior period error to the Condensed Consolidated Statement of Equity: Preferred Stock Common Stock Treasury Stock Shares Amount Shares Amount Additional Paid-in Capital Accumulated Deficit Shares Amount Total Stockholders’ Equity September 30, 2021 806,585 $ 1 13,732,713 $ 14 $ 172,898 $ (120,419 ) 1,015,493 $ (13,764 ) $ 38,730 Adjustment for correction of an error-Preferred dividends — — — — (176 ) 176 — — — Balance September 30, 2021-as adjusted 806,585 $ 1 13,732,713 $ 14 $ 172,722 $ (120,243 ) 1,015,493 $ (13,764 ) $ 38,730 December 31, 2021 1,252,299 $ 1 14,769,699 $ 15 $ 228,420 $ (123,684 ) 1,015,493 $ (13,764 ) $ 90,988 Adjustment for correction of an error-Preferred dividends — — — — (630 ) 630 — — — December 31, 2021-as adjusted 1,252,299 $ 1 14,769,699 $ 15 $ 227,790 $ (123,054 ) 1,015,493 $ (13,764 ) $ 90,988

Business Combination and Asset Acquisition [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 2,970,000 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, (the “Termination Agreement”), SCI paid HEL $725,000 and SHI issued to HEL 150,000 shares of our common stock (the “Termination Shares”). SCI also reimbursed HEL $75,000 for transaction-related fees and expenses. SHI included the termination costs as part of asset acquisition per ASC 805-50. Based on the closing price of the SHI common stock on Nasdaq”) on November 5, 2021, SHI has valued the aggregate termination consideration at approximately $1.9 million. 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 ( 2,970,000 within five years after the effective date of the merger, as set forth in the Merger Agreement and the schedules thereto, as set forth below . The Merger Consideration and the timing of the payment thereof is subject to the following qualifications and limitations: 1a) Upon buyer 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 19,800 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 29,700 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 14,850 Merger Shares per Active MW 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 2,970,000 to 1,485,000 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, June 30, 2022 or June 30, 2023, 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 our Board of Directors (the “Board”) 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. 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 million. 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	7. Income Taxes During the three and six months ended June 30, 2022, the Company’s effective income tax rate on the tax benefit was 1.75 3.32 0 21% 251 797 3 In connection with the strategic contract pipeline acquired in the Soluna Callisto acquisition as further discussed in Note 5, ASC 740-10-25-51 requires the recognition of 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 million at inception date, in which was recorded as a deferred tax liability and this amount will be amortized over the life of the asset. For the three and six months ended June 30, 2022, the Company amortized $547 thousand and approximately $1.1 million, respectively. 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 valuation allowance was $16.5 million and $ 11.9

Diluted income (loss) per share reflects the potential dilution, if any, computed by dividing income (loss) by the combination of dilutive common stock equivalents, comprised of shares issuable under outstanding investment rights, warrants and the Company’s stock-based compensation plans, and the weighted average number of shares of common stock outstanding during the reporting period. Dilutive common stock 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. The Company notes as continuing operations was in a Net loss position for the three and six months ended June 30, 2022 and 2021, as such basic and diluted Earnings-per-share (“EPS”) is the same amount as continuing operations acts as the control amount in which would cause antidilution.

Related Party Transactions	11. Related Party Transactions MeOH Power, Inc. On December 18, 2013, MeOH Power, Inc. and the Company executed a Senior Demand Promissory Note (the “Note”) in the amount of $ 380 334 329 Legal Services During the three and six months ended June 30, 2022, the Company incurred $ 1 2 7 15 HEL Transactions On January 8, 2020, the Company formed SCI as a wholly-owned subsidiary to pursue a new business line focused on cryptocurrency and the blockchain ecosystem. In connection with this new business line, SCI established a facility to mine cryptocurrencies and integrate with the blockchain network. Pursuant to an Operating and Management Agreement dated January 13, 2020, by and between SCI and HEL, HEL assisted the Company, and later SCI, in developing, and is now operating, the cryptocurrency mining facility. The Operating and Management Agreement requires, among other things, that HEL provide project sourcing services to SCI, including acquisition negotiations and establishing an operating model, investments/financing timeline, and a project development path, as well as developmental and operational services, as directed by SCI, with respect to the applicable cryptocurrency mining facility in exchange for SCI’s payment to HEL of a one-time management fee ranging from $ 65,000 350,000 237 Pursuant to the Operating and Management Agreement, during the developmental phase of the cryptocurrency mining facility, which ended on March 14, 2020, HEL gathered and analyzed information with respect to SCI’s cryptocurrency mining efforts and produced budgets, financial models, and technical and operational plans, including a detailed business plan, that it delivered to SCI in March 2020 (the “Deliverables”), all of which was designed to assist with the efficient implementation of a cryptocurrency mine. The agreement provided that, following SCI’s acceptance of the Deliverables, which occurred on March 23, 2020, HEL, on behalf of SCI, would commence operations of the cryptocurrency mine in a manner that would allow SCI to mine and sell cryptocurrency. In that regard, on May 21, 2020, SCI acquired the intellectual property of GigaWatt, Inc. (“GigaWatt”) and certain other property and rights of GigaWatt associated with GigaWatt’s operation of a crypto-mining operation located in Washington State. The acquired assets formed the cornerstone of SCI’s current cryptocurrency mining operation. SCI sells for U.S. dollars all cryptocurrency it mines and is not in the business of accumulating cryptocurrency on our balance sheet for speculative gains. On October 22, 2020, SCI loaned HEL $ 112 On November 19, 2020, SCI and HEL entered into a second Operating and Management Agreement related to a potential location for a cryptocurrency mine in the Southeast United States. In accordance with the terms of the agreement, which are consistent with the first Operating and Management agreement noted above, HEL is entitled to ongoing success payments of 20.0% of the earnings before interest, taxes, depreciation and amortization of the mine. SCI paid HEL $ 221 On December 1, 2020, SCI and HEL entered into a third Operating and Management Agreement with respect to a potential location for a cryptocurrency mine in the Southwestern United States. In accordance with the terms of the agreement, which are consistent with the first Operating and Management agreement noted above, HEL is entitled to ongoing success payments of 20.0% On February 8, 2021, SCI and HEL entered into a fourth Operating and Management Agreement related to a potential location for a cryptocurrency mine in the Southeast United States. In accordance with the terms of the agreement, which are consistent with the first Operating and Management agreement noted above, HEL is entitled to ongoing success payments of 20.0% of the earnings before interest, taxes, depreciation and amortization of the mine. SCI paid HEL $ 544 For the fiscal year ended December 31, 2021, the Company paid $ 245 Each Operating and Management Agreement, all of which were terminated effective November 5, 2021, pursuant to the Termination Agreement, among other things, required that HEL provide project sourcing services to SCI, including acquisition negotiations and establishing an operating model, investments/financing timeline, and project development path. The Company made one final payment to HEL in 2022 of $ 50 Simultaneously with entering into the initial Operating and Management Agreement with HEL, the Company, pursuant to a purchase agreement it entered into with HEL, made a strategic investment in HEL by purchasing 158,730 500 250 Technologies Investment I, LLC, a Delaware limited liability company that owns, on a fully diluted basis, 57.9% As discussed above, on October 29, 2021, we completed the Soluna Callisto acquisition pursuant to 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 SCI’s existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to SCI, which was formed expressly for this purpose, 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 the Merger Consideration. In connection with the Soluna Callisto acquisition, effective as of October 29, 2021, upon and subject to the terms and conditions of the Termination Agreement, on November 5, 2021: (1) the existing Operating and Management Agreements between HEL and SCI were terminated in all respects; and (2)(A) SCI paid HEL $ 725,000 Please see Note 5 for additional information regarding the Soluna Callisto acquisition and related transactions. Several of HEL’s equity holders are affiliated with Brookstone Partners, the investment firm that holds an equity interest in the Company through Brookstone Partners Acquisition XXIV, LLC. The Company’s two Brookstone-affiliated directors also serve as directors and, in one case, as an officer, of HEL and also have ownership interest in HEL. In light of these relationships, the various transactions by and between the Company and SCI, on the one hand, and HEL, on the other hand, were negotiated on behalf of the Company and SCI via an independent investment committee of the Board and separate legal representation. The transactions were subsequently unanimously approved by both the independent investment committee and the full Board. Five of the Company’s directors have various affiliations with HEL. Michael Toporek, our Chief Executive Officer and a director, owns (i) 90% of the equity of Soluna Technologies Investment I, LLC, which owns 57.9% of HEL and (ii) 100% of the equity of MJT Park Investors, Inc., which owns 3.1% of HEL, in each case on a fully-diluted basis. Mr. Toporek does not own directly, or indirectly, any equity interest in Tera Joule, LLC, which owns 9.2% of HEL; however, as a result of his 100% ownership of Brookstone IAC, Inc., which is the manager of Tera Joule, LLC, he has dispositive power over the equity interests that Tera Joule owns in HEL. In addition, one of the Company’s directors, Matthew E. Lipman, serves as a director and currently acting as President of HEL. Mr. Lipman does not directly own any equity interest in Tera Joule, LLC, which owns 9.2% of HEL; however, as a result of his position as a director and officer of Brookstone IAC, Inc., which is the manager of Tera Joule, LLC, he has dispositive power over the equity interests that Tera Joule owns in HEL. As a result, the approximate dollar value of the amount of Mr. Toporek’s and Mr. Lipman’s interest in the Company’s transactions with HEL for the three and six months ended June 30, 2022 was $0 and $0. John Belizaire and John Bottomley, who were elected to the Board upon the effective time of SCI’s acquisition of Soluna Callisto, serve as directors of HEL. In addition, Mr. Belizaire is the beneficial owner of 1,317,567 shares of common stock of HEL and 102,380 Class Seed Preferred shares, which are convertible into 86,763 shares of common stock of HEL. These interests give Mr. Belizaire an ownership of 10.54% in HEL. Mr. Belizaire also owns an interest in HEL indirectly through his 5.0139% interest of Tera Joule, LLC’s 965,945 Class Seed Preferred shares, which are convertible into 818,596 shares of common stock of HEL. Mr. Bottomley is the beneficial owner of 96,189, or approximately 0.72%, of the outstanding shares of common stock of HEL. Finally, William P. Phelan, Chairman of the Board, served as an observer on HEL’s board of directors on behalf of the Company through March 2021. The Company’s investment in HEL is carried at the cost of investment and was $ 750 1.79%

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 stock options, (ii) as unrestricted or restricted stock, and (iii) in settlement of restricted stock units shall be limited to (A) during the Company’s fiscal year ending December 31, 2021, 1,460,191 In the event that, prior to the date on which the 2021 Plan shall terminate, any Award granted under the 2021 Plan expires unexercised or unvested or is terminated, surrendered, or cancelled without the delivery of shares of common stock, or any Awards are forfeited back to the Company, then the shares of common stock subject to such Award may be made available for subsequent Awards under the terms of the 2021 Plan.

Effect Of Recent Accounting Updates
Effect of Recent Accounting Updates	13. Effect of Recent Accounting Updates Accounting Updates Not Yet Effective 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 There have been no other significant changes in the Company’s reported financial position or results of operations and cash flows as a result of our adoption of new accounting pronouncements or changes to our significant accounting policies that were disclosed in its consolidated financial statements for the fiscal year ended December 31, 2021 (the “2021 Fiscal Year”).

Segment Information	16. Segment Information The Company applies ASC 280, Segment Reporting No operating segments have been aggregated to form the reportable segments. The Company does not allocate all assets to the reporting segments as these are managed on an entity-wide basis. Therefore, the Company does not separately disclose the total assets of its reportable operating segments. The Cryptocurrency Mining segment generates revenue from the cryptocurrency the Company earns through its mining activities. The Data Center Hosting segment generates revenue from contracts for the provision/consumption of electricity and operation of the data center from the Company’s high performance computing facility in Calvert City, Kentucky.

Subsequent Events	17. Subsequent Events October SPA Addendum On July 19, 2022, the Company entered into the Addendum to amend certain terms of the October SPA and the October Security Agreement. Pursuant to the Addendum, among other things, the assets of the Company related to the Company’s development site in Texas which secure the Company’s obligations under the October Security Agreement will be released in three tranches in connection with three tranches of conversions or redemptions of the October Notes. In connection with the first tranche, $1,100,000 of October Notes was converted to common stock between July 25, 2022 and August 1, 2022; in connection with the second tranche, $1,100,000 of October Notes will be converted to common stock; and in connection with the third tranche, $1,100,000 of October Notes will be converted to common stock (each, the “Required Conversion Amount”), in each case at the then in effect Conversion Price. Prior to each conversion the Conversion Price of the Note will be reduced (but not increased) to a 20% discount to the 5-day volume-weighted average price (“VWAP”) of the common stock. The Conversion Price for the first tranche is $3.75. In addition, the October Purchasers may require the Company to redeem up to $2,200,000 worth of October Notes in connection with each tranche at a rate of $1.20 for every $1.00 owed, less the amount of October Notes converted during such tranche, not including the Required Conversion Amount if the October Purchasers are unable to convert out of such amount of the Notes in each tranche. Each tranche is equal to $3,300,000 of the October Notes and the Addendum contemplates that at least $9,900,000 of the October Notes may be reduced under the terms of the Addendum. 1,950,000 Pursuant to the Addendum, the exercise price of the Class A Warrants and Class B Warrants and 85,000 warrants to purchase common stock issued to the October Purchasers on January 13, 2022 was reduced to $9.50 a share. In addition, the Company agreed to exchange the Class C Warrants for 296,013 shares of common stock, which exchanges were completed between July 25, 2022 and August 1, 2022. Except under certain circumstances, the Company is prohibited from engaging in any capital raising transactions without the consent of the October Purchasers until the Company’s obligations under the October Security Agreement have been paid in full. Series B Convertible Preferred Stock Private Placement Securities Purchase Agreement On July 19, 2022, the Company entered into a Securities Purchase Agreement (the “Series B SPA”) with an accredited investor (the “Series B Investor”) pursuant to which the Company issued to the Series B Investor 62,500 shares of Series B Preferred Stock, for a purchase price of $5,000,000, on July 20, 2022 (the “Series B Closing”), which are initially convertible into 1,155,268 shares of our common stock (the “Series B Conversion Shares”), at a price per share of $5.41 (“Conversion Price”), a 20% premium to the close of the common stock on July 18, 2022, subject to adjustment as set forth in the Certificate of Designation (as defined below) governing the terms of the Preferred Stock. In addition on July 19, 2022, the Company issued to the Series B Investor common stock purchase warrants (collectively, the “Series B Warrants”) to purchase up to an aggregate of 1,000,000 shares of common stock at an initial exercise price of $10.00 per share of common stock (the “Series B Warrant Shares” and collectively with the Series B Preferred Stock, the Series B Conversion Shares, and the Series B Warrants, the “Series B Securities”). In addition, at the Series B Closing, the Investor delivered to the Company a warrant to acquire 1,000,000 shares of common stock at an exercise price of $11.50 per share for cancellation. Until the earlier of (i) three years after the Series B Closing or (ii) if in excess of $500,000 of Series B Preferred Stock or at least 100,000 Series B Warrants remain outstanding, the Company agreed not to (a) issue any common stock, common stock equivalents, preferred stock or other equity securities at a price that is less than the highest price per share of the Series B Securities, (b) file any registration statement, with certain exceptions, or (c) enter into an equity line of credit or at the market offering. In addition, the Company may buy out the rights of the Series B Investor under the preceding sentence for $10,000,000 less any Profit (as defined in the Series B SPA) the Series B Investor has earned from the Series B Securities, including pursuant to any amount paid for waiver under the following sentences. The Series B Investor has a right of first refusal with respect to the offerings described in the first sentence of this paragraph for a period of three years beginning on the later of (i) January 1, 2023 and (ii) the date the October Notes have been fully redeemed or converted. The Company can obtain the Series B Investor’s waiver to the right of first refusal by delivering to the Series B Investor 10% of the amount raised by the Company in any such offering in cash or in the same securities issued by the Company.

Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and our wholly-owned subsidiary, SCI, as of June 30, 2022 and for the three and six months ended June 30, 2022 and 2021, also includes the accounts of our then wholly-owned subsidiary, MTI Instruments. All intercompany balances and transactions are eliminated in consolidation.
Change in Par Value	Change in Par Value Unless otherwise noted, all capital values, share and per share amounts in the condensed consolidated financial statements have been retroactively restated for the effects of the Company’s change in par value from $0.01 to $0.001, which became effective after the redomestication to the State of Nevada on March 29, 2021.
Reclassification	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. The reclassifications relate to the presentation of discontinued operations and a correction of an error.
Correction of an Error	Correction of an Error The Company recorded cash preferred dividend distributions of $630 thousand in the Annual Report presentation as an increase within accumulated deficit. However, in the absence of retained earnings, cash dividends should generally be charged to Additional-Paid-in Capital (“APIC”). This treatment is supported by Accounting Standards Codification (“ASC”) 480-10-S99-2, which requires accretion of redeemable preferred stock to be charged to APIC in the absence of retained earnings. As the Company did not have accumulated profit (i.e.: absence of retained earnings), the preferred cash dividends should have been charged to APIC.
