Notes to Condensed Consolidated Financial Statements (Unaudited)

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.”

SHI currently conducts its business through its wholly-owned subsidiary, Soluna Computing, Inc. (“SCI”). SCI is engaged in mining of cryptocurrency through data centers that can be powered by renewable energy sources. Recently, SCI has built modular data centers that are used for cryptocurrency mining though proprietary mining and hosting business models. SCI intends to continue to develop and build, modular data centers that use wasted renewable energy for cryptocurrency mining and in the future can be used for intensive, high performance computing applications, such as artificial intelligence and machine learning, with the goal of providing a cost-effective alternative to battery storage or transmission lines.

SCI was incorporated in Delaware on January 8, 2020 as EcoChain, Inc., which operates cryptocurrency mining facilities that perform proprietary mining and data hosting services that integrate with the cryptocurrency blockchain network. 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”). We earn revenue from this business as the mined cryptocurrencies are converted into U.S. dollars. 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 shut down. On April 6 and June 28, 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 September 30, 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 megawatts 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 September 30, 2023, has a 15% ownership interest in Soluna DVSL ComputeCo, LLC (“DVSL”), and 51% ownership interest in Soluna DV ComputeCo, LLC (“DV”) in which are included within the Project Dorothy site, as discussed further in Note 16.

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% of the issued and outstanding common stock of MTI Instruments. As a result of the foregoing, the MTI Instruments business was reported as discontinued operations in our consolidated financial statements as of December 31, 2022, and prior periods included in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 31, 2023 (the “Annual Report”). 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.

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 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 $7.8 million.

Going Concern and Liquidity

The Company’s condensed unaudited financial statements as of September 30, 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 condensed unaudited financial statements, the Company did not generate sufficient revenue to generate net income and has a cash used in operations position during the nine months ending as of September 30, 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 condensed unaudited financial statements as of September 30, 2023, or November 14, 2023.

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 million. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Soluna MC, LLC (“Guarantor”), under a piercing of the corporate veil claim relating to the Guarantor together with Borrower, (“NYDIG Defendants”) debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023, seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

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.

7

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 million in project financing subject to various milestones and conditions precedent and in August 2022, the Company entered into an agreement with Spring Lane for an initial funding of up to $12.5 million from the previously agreed-upon $35.0 million commitment from Spring Lane for Project Dorothy for a 32% ownership as of year-end. As of December 31, 2022, the Company had received approximately $4.8 million worth of contributions from Spring Lane. In February and concluding on March 10, 2023, the Company entered into a series of Purchase and Sale Agreements with Spring Lane for a total purchase price of $7.5 million for the sale of Series B membership interests owned by SHI. The capital was funded and used to help complete the substation interconnection and the final stages of Project Dorothy, Soluna’s flagship project in West Texas, and corporate operations and general expenses of Soluna. In this series of transactions, Spring Lane increased its stake in Soluna DVSL ComputeCo from approximately 32% to 85% and reduced SHI’s ownership from 68% to 15%.

In addition, on May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DV”) through Soluna DV Devco, LLC completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC, (“Navitas”) organized by Navitas Global, to complete the second phase of the Dorothy Project (“Dorothy 1B”). Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which the Company had contributed capital expenditures for the data center. Navitas has approximately $12.1 million cash contribution for the primary purpose of purchasing proprietary cryptocurrency miners and equipment necessary to put the Dorothy 1B Project into service. As a result of the contribution, the Company owns 51% of DV and Navitas owns 49% of DV.

On August 1, 2023, the Company had the second subsequent closing under the Securities Purchase Agreement dated December 5, 2022 among the Company and certain institutional investors. Pursuant to the SPA, the investors purchased approximately $774,000 in common stock and associated common stock purchase warrants, with a purchase price of $7.50 per share. Accordingly, at the second subsequent closing the Company issued to the investors 103,183 shares of Common Stock, together with associated warrants to purchase 206,367 shares of Common Stock.

For the first nine months ended September 30, 2023, the Company has sold under-utilized miners and equipment, and continues to evaluate opportunities to sell more miners and equipment for fiscal year 2023. In addition to the proceeds from the foregoing transactions and together with the Company’s available cash on hand for available use of approximately $5.6 million as of September 30, 2023, the Company will need additional capital raising activities, to meet its outstanding commitments relating to capital expenditures as of September 30, 2023 of approximately $150 thousand and other operational needs, as well as additional needs during 2023 and management continues 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.

2. Basis of Presentation

In the opinion of management, the Company’s condensed unaudited 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, 2022 (“the Annual Report”).

The information presented in the accompanying condensed consolidated balance sheet as of December 31, 2022 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, 2023 and September 30, 2022.

Principles of Consolidation

The condensed unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, SCI. 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 (the “Reverse Split”). The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023. The reverse stock split was approved by the Board of Directors and by shareholders at the annual meeting of the stockholders on June 29, 2023. At the effective time, 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 Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole 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 for continued listing on the Nasdaq. On October 30, 2023, the Company received a notice of compliance from NASDAQ.

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 per share (the “Series B Preferred Stock”), may be converted to Common Stock. The total number of shares of Series B Preferred Stock of the Company authorized for issuance remained at 187,500.

8

The effects of the Reverse Stock Split have been reflected in these condensed unaudited consolidated 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 and Restricted Cash

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months. As of September 30, 2023 and December 31, 2022, the Company had approximately $5.6 million and $1.1 million within cash and cash equivalents. In addition, for cash flow purposes, the Company had approximately $1.1 million as of September 30, 2022 within cash and cash equivalents.

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, 2023, the Company had restricted cash of approximately $4.4 million, in which $3.4 million was classified as current and $1.0 million was classified as non-current. On December 31, 2022, the Company had restricted cash of approximately $685 thousand, in which the entire balance was classified as current. The Company notes that there was no restricted cash balance as of September 30, 2022 for cash flow purposes. The balance in restricted cash relates to funds held in escrow accounts due to sales of equipment that were executed, in which the Company can release to the convertible noteholders only if they request their share of funds. If no funds are distributed to the convertible noteholders from the escrow account by December 31, 2023, the funds may be used for general purposes for the Company. In addition, there was a restricted deposit held with a customer that was for less than 12 months. The Company has a long term restricted cash balance in relation to a collateralized deposit.

Deposits and credits on equipment

As of September 30, 2023 and December 31, 2022, the Company had approximately $975 thousand and $1.2 million in deposits and credits on equipment, that had not yet been received by the Company as of the year end. Once the Company receives such equipment in the subsequent period, the Company will reclassify such balance into Property, Plant, and Equipment. The credit on equipment is restricted to be used on future purchases by March 1, 2024 (“expiration date”). The Company notes that if an order is not executed by the expiration date, the credit would be forfeited. The Company intends to utilize the full credit balance for future orders prior to the expiration date.

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.

3. Accounts Receivable

Depreciation expense was approximately $1.2 million and $6.0 million for the three months ended September 30, 2023 and 2022, respectively. Depreciation expense was approximately $2.4 million and $15.9 million for the nine months ended September 30, 2023 and 2022, respectively.

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 million in which were written off the Company’s books in the first quarter of 2023, offsetting the outstanding accrued interest and penalty first, then the remaining outstanding loan. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling approximately $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing.

In January 2023, the Company sold M20 and M21 miners for a loss on sale of equipment of approximately $82 thousand in which we received proceeds of $213 thousand for our M20 and M21 miners which were previously reported as held for sale as of December 31, 2022, in which had a net book value of $295 thousand. There were additional proceeds of $36 thousand in March 2023, in which resulted in a gain of approximately $3 thousand of scrap and other equipment. This was offset with a gain on sale of approximately $48 thousand in relation to the sale of M30 miners in May and June of 2023, which the Company sold the miners for a higher value than the current net book value. The Company received proceeds of approximately $561 thousand in which the miners had a net book value of approximately $513 thousand. In addition, the Company sold Switchgear and M31 miners for cash proceeds of approximately $476 thousand in which no gain or loss was recognized as the switchgear and miners were sold at net book value. For the three months ended September 30, 2023, the Company incurred a loss on sale of fixed assets of approximately $373 thousand in relation to the sale of miners for Project Sophie and sale of the remaining Project Marie fixed assets including the Tesseracks (mobile, Bitcoin Mining Equipment). For Project Sophie, the Company incurred a loss on sale of approximately $30 thousand in which was due to the shift at the project site to data hosting services compared to proprietary mining beginning in the second quarter of fiscal 2023, the Company was looking to sell all the miners at the site as noted below within “Equipment held for sale”. The miners sold at the Sophie site were sold for proceeds of approximately $891 thousand in which had a net book value of approximately $921 thousand. For Project Marie, the Company sold the Tesseracks and remaining assets for a loss of approximately $92 thousand for the three months ended September 30, 2023 in which the Company received proceeds of $320 thousand in which included a note receivable of $240 thousand that is outstanding as of September 30, 2023. In addition, the Company incurred approximately a $251 thousand loss on sale of assets in relation to NYDIG collateral finalization in which the Company had to pay for expenses and legal fees in related to the disposition. The Company incurred a $1.0 million and $2.6 million loss for the three and nine months ended September 30, 2022 in connection with the disposal of miners and equipment with a net book value of approximately $3.3 million and $5.4 million for the three and nine months ended September 30, 2022 in which the Company received proceeds of $2.35 million and $2.8 million for the three and nine months ended September 30, 2022.

During the nine months ended September 30, 2023, the Company had impairment charges of approximately $418 thousand in which related to impairment of approximately $165 thousand for power supply units (PSUs) at the Sophie location, $84 thousand for M31 miners based on sales of other recent M31 miners, in which the Company wrote down the net book value to sale price of the sold M32 miners, and $169 thousand due to revaluing the S19 miners to the current market conditions. During the three and nine months ended September 30, 2022, the Company concluded that there were impairment indicators on property, plant and equipment associated with the S-9 and L3 miners in storage. As a result, a quantitative impairment analysis was required as of September 30, 2022. As such, the Company reassessed its estimates and forecasts as of September 30, 2022, to determine the fair values of the S-9 and L3 miners held in storage. As a result of the analysis, as of September 30, 2022, the Company concluded the carrying amount of the property, plant and equipment associated with the S-9 and L3 miners exceeded its fair value, which resulted in impairment charges of $1.2 million and $2.0 million on the condensed unaudited consolidated statements of operations for the three and nine months ended September 30, 2022. In addition, the Company assessed the active miners in operations and determined there has been a decline in the market value of the active miners in the Company’s operations. As a result, a quantitative impairment analysis was required as of September 30, 2022. As such, the Company reassessed its estimates and forecasts as of September 30, 2022, to determine the undiscounted cash flows to determine whether the miners would be recoverable. It was determined based on the analysis, that the undiscounted cash flow with residual value was less than the net book value as of September 30, 2022, confirming the existence of a triggering event, and therefore required an impairment to be recognized. Based on the fair value of the active miners compared to the net book value, the Company determined that an impairment of approximately $26.8 million to be recognized for the three and nine months ended September 30, 2022.

Equipment held for sale

In April 2023, Project Sophie entered into a 25 MW hosting contract with a sustainability-focused Bitcoin miner, in which has shifted the Company’s business model at the Company’s modular data center at Project Sophie from proprietary mining to hosting Bitcoin miners for the customer. The Company is currently selling existing Bitcoin miners at the site and redeploying capital. The Company obtained Board of Director approval to sell all remaining miners at the Sophie location and as of September 30, 2023, approximately $248 thousand to be sold which the Company expects to sell within a year.

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 shares (the “Merger Shares”) of the Company’s common stock payable upon the achievement of certain milestones within five years after the effective date in the merger, as set forth in the merger agreement and the schedules thereto (the “Merger Consideration”). See Note 11 for further information regarding our relationship with HEL.

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 $725,000 and SHI issued to HEL 6,000 shares of SHI 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 (118,800) issuable as Merger Consideration, which issuance is contingent on the achievement of certain milestones of generating active Megawatts from Qualified Projects in which the Cost Requirement is satisfied 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 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);

11

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% of the outstanding equity securities of SCI and/or the surviving corporation, or (C) a merger, consolidation, or other transaction in which the holders of SHI’s, SCI’s, or the surviving corporation’s outstanding voting securities immediately prior to such transaction own, immediately after such transaction, securities representing less than 50% of the voting power of the corporation or other entity surviving such transaction (excluding any such transaction principally for bona fide equity financing purposes, so long as, in the case of SHI or SCI (but not the surviving corporation) such transactions, individually and in the aggregate, do not result in a change in membership of such entity’s board of directors so that the persons who were members of the board of directors immediately prior to the first such transaction constitute less than 50% of the board membership at any time after such transaction(s) are consummated). Notwithstanding the foregoing, a transaction shall not constitute a Change of Control if its sole purpose is to change the state of SHI’s or SCI’s incorporation or to create a holding company that will be owned in the same proportions by the persons who held SHI’s or SCI’s securities immediately prior to such transaction; and
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 has 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 and 39,600 Merger Shares were issued on May 26, 2023 and October 10, 2023. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 59,400 Merger Shares, a total of 59,400 Merger Shares remain available for possible issuance pursuant to the terms of the Merger Agreement.

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.

Total	$	47,541	$	18,171	$	29,370

Intangible assets consist of the following as of December 31, 2022:

(Dollars in thousands)	Intangible Assets		Accumulated Amortization		Total
Strategic pipeline contract	$	46,885	$	10,940	$	35,945

Patents		110		6		104
Total	$	47,495	$	11,063	$	36,432

Amortization expense for the three months ended September 30, 2023 and 2022 was approximately $2.4 million and $2.4 million, respectively. Amortization expense for the nine months ended September 30, 2023 and 2022 was approximately $7.1 million and $7.1 million, respectively.

The strategic pipeline contract relates to supply of a critical input to our digital mining business. The Company has analyzed this strategic pipeline contract similar to a permit for future benefit. The strategic pipeline contract relates to potential renewable energy data centers that fit in the alignment of the Company structure to expand operations of the Company’s new focus in their business.

The Company expects to record amortization expense of intangible assets over the next five years and thereafter as follows:

7. Income Taxes

During the three and nine months ended September 30, 2023, the Company’s effective income tax rate was -4.52% and 1.57%, and for the three and nine months ended September 30, 2022, the Company’s effective tax rate on the tax benefit was -0.96% and -1.66%. The projected annual effective tax rate is less than the Federal statutory rate of 21%, primarily due to the change in the valuation allowance, as well as changes to estimated taxable income for 2023 and permanent differences. There was $569 thousand income tax expense and $547 thousand deferred income tax benefit for the three months ended September 30, 2023 and 2022. There was $524 thousand and $1.3 million deferred income tax benefit for the nine months ended September 30, 2023 and 2022.

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 nine months ended September 30, 2023 and 2022, the Company amortized $547 thousand and $1.6 million.

13

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 $35.6 million and $30.7 million on September 30, 2023 and December 31, 2022, respectively. We will continue to evaluate the ability to realize our deferred tax assets and related valuation allowance on a quarterly basis.

8. Debt

Convertible Notes Payable

Debt consists of the following

(Dollars in thousands):

	Maturity Date	Interest Rate			September 30, 2023		December 31, 2022
Convertible Note	July 25, 2024		*18	%	$	10,796	$	12,254

Less: debt issuance costs						-		42
Total convertible notes, net of discount and issuance costs					$	10,796	$	11,737

* Default interest was waived on March 10, 2023

On October 25, 2021, pursuant to a Securities Purchase Agreement (the “October SPA”), the Company issued to certain accredited investors (the “Noteholders”) (i) secured convertible notes in an aggregate principal amount of $16.3 million for an aggregate purchase price of $15 million (collectively, the “October Secured Notes”), which were, subject to certain conditions, convertible at any time by the investors, into an aggregate of 71,043 shares of the Company’s common stock, at a price per share of $229.50 and (ii) Class A, Class B and Class C common stock purchase warrants (collectively, the “October Warrants”) to purchase up to an aggregate of 71,043 shares of common stock, at an initial exercise price of $312.50, $375 and $450 per share, respectively. The October Warrants are legally detachable and can be separately exercised immediately for five years upon issuance, subject to applicable Nasdaq rules.

The October Secured Notes, subject to an original issue discount of 8%, had a maturity date (the “Maturity Date”) of October 25, 2022, which was extended to April 25, 2023 pursuant to the Addendum Amendment (as defined below), upon which date the October Secured Notes shall be payable in full. Commencing on the Maturity Date and also five (5) days after the occurrence of any Event of Default (as defined in the October Secured Notes), interest on the October Secured Notes will accrue at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. If any Event of Default or a Fundamental Transaction (as defined in the October Secured Notes) or a Change of Control (as defined in the October Secured Notes) occurs, the outstanding principal amount of the October Secured Notes, liquidated damages and other amounts owing in respect thereof through the date of acceleration, will become, at the Noteholder’s election, immediately due and payable in cash at the Mandatory Default Amount (as defined in the October Secured Notes). The October Secured Notes may not be prepaid, redeemed or mandatorily converted without the consent of the Noteholders. The obligations of the Company pursuant to the October Secured Notes are (i) secured to the extent and as provided in the Security Agreement, dated as of October 25, 2021, by and among the Company, MTI Instruments and SCI, Soluna MC, LLC and Soluna SW, LLC (both of which are wholly owned subsidiaries of SCI, and together with MTI Instruments and SCI, the “Subsidiary Guarantors”), and Collateral Services LLC (the “Collateral Agent”), as collateral agent for the Noteholders; and (ii) guaranteed, jointly and severally, by the Subsidiary Guarantors pursuant to each Subsidiary Guaranty, dated as of October 25, 2021, by and among each Subsidiary Guarantor and the Noteholders signatory to the October SPA, subject to subsequent modifications pursuant to the Addendum, the Addendum Amendment and the NYDIG Transactions.

14

On April 24, 2023, the Company reached agreement with the holders of the outstanding Convertible Notes to extend the maturity thereof until May 25, 2023. On May 11, 2023, the Company entered into a Second Amendment Agreement (the “Second Amendment”) as discussed further below with the holders of its October Secured Notes to extend the maturity date of the October Secured Notes to July 25, 2024.

On July 19, 2022, the Company entered into an addendum to the October SPA (the “Addendum”), pursuant to which a portion of the October Secured Notes would be converted and may be redeemed in three tranches, with each tranche of $1,100,000 required to be converted into common stock in each case at the then in effect conversion price of the October Secured Notes, with such price, prior to each conversion, to be reduced (but not increased) to a 20% discount to the 5-day volume weighted average price (“VWAP”) of the Company’s common stock. In addition, the Noteholders may require the Company to redeem up to $2,200,000 worth of October Secured Notes in connection with each tranche at a rate of $1.20 for every $1.00 owed, less the amount of October Secured Notes converted during such tranche, not including the required conversion amount if the Noteholders are unable to convert out of such amount of the October Secured Notes in each tranche. The Company is also required to deposit up to $1,950,000 in an escrow account in connection with each tranche to satisfy any redemptions, except with respect to the first tranche as provided in the Addendum Amendment (as defined below). The Addendum also provides the right for the Company to pause the commencement of the conversion of the second and third tranches each for 45 days in the event the Company pursues an equity financing. Pursuant to the Addendum, the exercise price of the Class A Warrants and Class B Warrants and certain other warrants to purchase up to 3,400 shares of common stock issued to the Noteholders on January 13, 2022, was reduced from $331.50 to $237.50 per share. In addition, the Company agreed to exchange the Class C Warrants for 11,841 shares of common stock, which exchanges were completed between July 25, 2022 and August 1, 2022.

On September 13, 2022, the Company and the Noteholders entered into an agreement further amending the Addendum (the “Addendum Amendment”), which among other matters, extended the Maturity Date of the October Secured Notes by six months to April 25, 2023, and increased the principal amount of the October Secured Notes by an aggregate of $520,241 for a total outstanding principal amount of $13,006,022. Also pursuant to the Addendum Amendment, $1.0 million previously deposited by the Company and held in escrow pursuant to the Addendum, was released back to the Company upon signing of the Addendum Amendment; however, on or before October 17, 2022, the Company (i) must deposit $1,000,000 into escrow as the Third Deposit, (ii) will not be required to make the second deposit of $1,950,000 pursuant to the Addendum and the Addendum Agreement, or redeem the first tranche of October Secured Notes. 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. In addition, pursuant to the Addendum Agreement, the Company issued to the Noteholders (i) 17,223 shares of the common stock (“New Shares”) in exchange for the Class B warrants, (ii) Class D common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $87.50 per share, (iii) Class E common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $112.50 per share, (iv) Class F common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $137.50 per share, and (v) Class G common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $187.50 per share (together, the “New Warrants”). The New Warrants are exercisable immediately and have exercise period of 5 years from the issuance date.

Pursuant to the Addendum, between July 21, 2022 to August 3, 2022, the October Secured Notes with an aggregate principal amount of $1,100,000 converted into 11,734 shares of common stock, at the conversion price of $93.75. Pursuant to the Addendum and Addendum Amendment, the Company evaluated whether the new addendums qualified as debt modification or debt extinguishment, and based on ASC 470, Debt, the Company determined the Addendum and Addendum Amendment to fall under Debt Extinguishment and the Company would be required to fair value the new debt, and in turn write off the existing debt on the books. Based on the Company’s assessment, an extinguishment of debt of approximately $12.8 million was recorded in July and September of 2022 based on the Addendum and Addendum Amendment, the October Secured Notes had an aggregate principal amount of approximately $13.0 million and a fair value of approximately $14.1 million outstanding after the debt extinguishment. The fair value of the New Warrants issued to the Noteholders on September 13, 2022 was approximately $8.6 million and recorded as part of the loss on extinguishment of debt. The residual fair value of the New Warrants issued to non-lenders was $892 thousand and was recorded as equity with the offset as debt discount against the residual proceeds, in which the entire $892 thousand has been amortized, in which $0 and $474 thousand related to the three and nine months ended September 30, 2023. All the original debt issuance costs were written off with the extinguishment of the debt, and with the Addendum Amendment. As of the year ended December 31, 2022, the Company had to fair value the outstanding debt, in which it was determined to be approximately $12.3 million of a principal outstanding balance of approximately $13.0 million, in which the change in valuation compared to September 2022 when the Company had an extinguishment recorded, was recorded as a revaluation gain for the year ended December 31, 2022.

15

In connection with the Second Amendment, the Company paid an extension fee of $250,000 and increased the principal amount of the outstanding October Secured Notes by 14%. The Company also issued 240,000 new Class A warrants exercisable at $12.50 and 80,000 new Class B warrants exercisable at $20.00.

Subject to the Equity Conditions (as defined below), upon each trigger set forth below, the Company is allowed, once per trigger, require the Note holders to convert up to 20% percent of the outstanding amount of the October Secured Notes as:

(i)	the Company’s Common Stock trades for 10 consecutive days at or above $12.50 per share and at least 40,000 shares trade on each day.
(ii)	the Company’s Common Stock trades for 10 consecutive days at or above $17.50 per share and at least 40,000 shares trade on each day.
(iii)	the Company’s Common Stock trades for 10 consecutive days at or above $22.50 per share and at least 40,000 shares trade on each day.

The Equity Condition is met if all of the following conditions have been met: (i) the shares of Common Stock issuable upon the conversion are either registered under the Securities Act of 1933 or resellable under Rule 144 thereunder without any volume restrictions, (ii) the number of shares issuable to each Note holder are below 4.99% of the outstanding shares, (iii) at least 20 trading days has elapsed since the previous mandatory conversion, (iv) the Company is current in all the SEC filings, and (v) the Company has obtained all required approvals from NASDAQ, or any successor trading market, to list the Common Stock to be issued upon such conversion.

With the Second Amendment on May 11, 2023, the principal value was reestablished to approximately $13.3 million, and a new fair value was established at approximately $10.94 million. The Second Amendment caused an extinguishment of debt of approximately $1.9 million which includes a loss on revaluation of the debt of $554 thousand and warrant valuation of New Class A and Class B warrants of $1.33 million. In addition, there was a $250 thousand extension fee cash payment that was included within “Other expense, net” on the condensed unaudited consolidated financial statements for the nine months ended September 30, 2023. The Company had approximately $1.05 million of note conversions between May 11, 2023 and September 30, 2023. The Company performed a fair value assessment as of September 30, 2023, and had a debt revaluation loss of approximately $625 thousand. For the three and nine months ended September 30, 2023, the Company had a net loss on debt revaluation and extinguishment of approximately $736 thousand and $2.3 million, respectively.

Following the debt extinguishment on July 19, 2022 as noted further 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. In addition, due to the extinguishment of debt in relation to the Second Amendment on May 11, 2023, the Company needed to perform a fair value analysis as of the date of extinguishment. For the year-ended December 31, 2022 and quarters-ended March 31, 2023, June 2023 and September 30, 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 period ends. The Company determined the fair value of the Convertible Notes uses certain Level 3 inputs.

In accordance with the most favored nation provision (“MFN Provision”), following the issuance of the December 2022 Shares and the December 2022 Warrants, we reduced the conversion price of the October Secured Notes to $19.00 per share. We held a special meeting on March 10, 2023 of our stockholders for the purpose of obtaining stockholder approval for a reduction in the conversion price of the October Secured Notes, subject to a conversion price floor of $7.50 per share, which amount represented the closing price of our Common Stock on the Nasdaq Stock Market on January 3, 2023, the first trading day of the 2023 fiscal year.

In connection with the December 2022 Offering, we also agreed to amend certain existing warrants to purchase up to an aggregate of: (i) 23,681 shares of our Common Stock at an exercise price of $237.50 per share and an expiration date of October 25, 2026; (ii) 40,000 shares of our Common Stock at an exercise price of $87.50 per share and with an expiration date of September 13, 2027; (iii) 40,000 shares of our Common Stock at an exercise price of $112.50 per share and with an expiration date of September 13, 2027; (iv) 40,000 shares of our Common Stock at an exercise price of $137.50 per share and with an expiration date of September 13, 2027; (v) 40,000 shares of our Common Stock at an exercise price of $7.50 per share and an expiration date of September 13, 2027; and (vi) 3,400 shares of Common Stock at an exercise price of $187.50 and an expiration date of January 14, 2025, held by the Noteholders (collectively, the “Noteholder Warrants”) so that the amended Noteholder Warrant would have an exercise price of $19.00 per share. The Company evaluated the warrant exercise price adjustment from the values noted above to $19.00 noting the total dollar value impact in which the Noteholder Warrant’s new fair value, as a result of the exercise price revision, exceeded the previous warrant instrument was approximately $370 thousand, the Company deemed the change in exercise price was in contemplation with the December 2022 offering, as such was recognized as a deferred cost of the offering against the proceeds.

The events of default stated in the Notice of Acceleration and Repossession defined below with NYDIG Financing constituted a cross-default under the terms of secured convertible notes issued to the Noteholders. In addition to such cross-default, the failure of the Company pursuant to the Addendum dated as of July 19, 2022, to escrow an aggregate amount of $950,000 for the benefit of the Noteholders by December 21, 2022, constituted an event of default under the Notes. Due to the defaults noted, the Company did not enter into the second and third tranche of conversions. As such, beginning on November 30, 2022, the Company has been accruing interest of 18% per annum on the outstanding principal amount due to the default which amounted to $617 thousand as of March 10, 2023. On March 10, 2023, the Company entered into a Second Addendum Amendment with the Noteholders, in which the Company paid the accumulated default accrued interest of $617 thousand through the Company’s restricted escrow accounts and contemporaneously with the payment, the Noteholders waived all existing events of default arising under the convertible notes.

* Due to event of default- the entire NYDIG Financing became current, see note below.

On December 30, 2021, Soluna MC Borrowing 2021-1 LLC (the “Borrower”), an indirect wholly owned subsidiary of the Company entered into a Master Equipment Finance Agreement (the “Master Agreement”) with NYDIG ABL LLC (“NYDIG”) as lender, servicer and collateral agent (the “NYDIG facility”). The Master Agreement outlined the framework for a financing up to approximately $14.4 million in aggregate equipment financing. Subsequently, the parties negotiated the specific terms of each equipment financing transaction as well as the terms upon which the Noteholders would consent to the transactions contemplated by the Master Agreement.

On January 14, 2022, the Borrower effected an initial drawdown under the Master Agreement in the aggregate principal amount of approximately $4.6 million that bore interest at 14% and was to be repaid over 24 months. On January 26, 2022, the Borrower had a subsequent drawdown of $9.8 million. As part of the transactions contemplated under the Master Agreement, (i) the Company’s indirect wholly owned subsidiary, Soluna MC LLC, formerly EcoChain Block LLC (“Guarantor”), which is the owner of 100% of the equity interests of Borrower, executed a Guaranty Agreement in favor of NYDIG, as lender, dated as of December 30, 2021 (the “Guaranty Agreement”), (ii) Borrower has granted a lien on, and security interest in, all of its assets to NYDIG, as collateral agent, (iii) Guarantor entered into an equipment financing arrangement on assets purchased with the borrowed funds, (iv) Borrower would borrow from NYDIG the loans as forth in certain loan schedules (the “Specified Loans”), and (v) Borrower had executed a Digital Asset Account Control Agreement (the “ACA Wallet Agreement”) with NYDIG, as collateral agent and secured party, and NYDIG Trust Company LLC, as custodian, dated as of December 30, 2021, as well as such other agreements related to the foregoing as mutually agreed (collectively, the “NYDIG Transactions”).

In connection with the NYDIG Transactions, on January 13, 2022, the Company entered into a Consent and Waiver Agreement, dated as of January 13, 2022 (the “Consent”), with the Noteholders, in connection with the October SPA, pursuant to which the Noteholders agreed to waive any lien on, and security interest in, certain assets, provided various contingencies are fulfilled, and each Noteholder who acquired October Secured Notes having a principal amount of not less than $3,000,000 agreed to waive its rights under Section 4.17 of the October SPA to participate in Subsequent Financings (as defined in the October SPA) with respect to the NYDIG Transactions and any additional loans under the MEFA that only finance the purchase of equipment from NYDIG, in order to consent to the NYDIG Transactions. Pursuant to the Consent, the Noteholders also waived the current requirement of the October SPA and the other transaction documents (collectively, the “SPA Documents”) that the Borrower become an Additional Debtor (as defined in the Security Agreement) and execute an Additional Debtor Joinder (as defined in the Security Agreement) for so long as the Specified Loans were outstanding, and NYDIG would not have entered into a subordination or intercreditor agreement with respect to the Guaranty. Further, pursuant to the Consent, the Noteholders waived the right to accelerate the Maturity Date of the October Secured Notes and the right to charge a default rate of interest on such Notes, in each case, with respect to certain changes in names of, and jurisdiction of incorporation, of the Debtors (as defined in the SPA Documents), which waiver would not waive any other Event of Default (as defined in any of the SPA Documents), known or unknown, as of the date of Consent.

Promptly after the date of the Consent, the Company issued warrants to purchase up to 3,400 shares of common stock to the Noteholder holding the largest outstanding principal amount of October Secured Notes as of the date of the Consent. Such warrants were substantially in form similar to the other warrants held by the Noteholders. Such warrants were exercisable for three years from the date of the Consent at an exercise price of $237.50 per share. On December 5, 2022, the exercise price of the warrants were reduced to an exercise price of $19.00 per share, effective with the closing of the Securities Purchase Agreement Offering on December 5, 2022.

The Company, through the Borrower, was required to make average monthly principal and interest payments to NYDIG of approximately $730 thousand on initial drawdown in aggregate principal amount of approximately $4.6 million bearing interest at 14%, and a subsequent drawdown of $9.8 million.

On December 20, 2022, the Borrower received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG with respect to the Master Agreement, by and between Borrower and NYDIG. The obligations of Borrower under the Master Agreement 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.

18

The NYDIG Notice states that (a) Borrower failed to observe or perform certain covenants, conditions or agreements contained in the Master Agreement 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 Master Agreement, and (b) Borrower defaulted under the guaranty, collateral agreement, or other support agreement, which resulted in an event of default under the Master Agreement. In addition, the NYDIG Notice states that Borrower failed to pay certain payments of principal and interest under the Master Agreement when due, which failure also constituted an event of default under the Master Agreement. As a result of the foregoing events of default, and pursuant to the Master Agreement, NYDIG (x) declared the principal amount of all loans due and owing under the Master Agreement and all accompanying Loan Documents (as defined in the Master Agreement) 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 Master Agreement and the Loan Documents, and (z) demanded the return of all equipment subject to the Master Agreement and the Loan Documents. As such, the principal balance of $10.5 million became due immediately and the Borrower was to bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. Also, as the Company was not able to obtain a waiver, the outstanding deferred financing costs were written off. As of December 31, 2022, the Borrower had incurred accrued interest and penalty of approximately $274 thousand. On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing. As of September 30, 2023, the Company has an outstanding loan balance of approximately $8.0 million and an outstanding accrued interest and penalties of approximately $810 thousand.

Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

The line of credit bears interest at a rate of Prime + 0.75% per annum. Accrued interest is due monthly and principal is due in full following KeyBank’s demand. As of January 1, 2022, the entire line of credit of $1.0 million was drawn and outstanding. As of September 30, 2023, the entire $1.0 million has been paid down, and the Company does not have any remaining balance outstanding. The Company does not plan to draw down on the line of credit in the foreseeable future. In addition, future drawdowns may require pre-approval by KeyBank.

The Company has two series of preferred stock outstanding: the Series A Preferred Stock, with a $25.00 liquidation preference; and the Series B Convertible Preferred Stock, par value $0.0001 per share, with a stated value equal to $100.00 (the “Series B Preferred Stock”).

Pursuant to the Certificate of Designations, Preferences and Rights of 9.0% Series A Cumulative Perpetual Preferred Stock of the Company, dividends, when, as and if declared by the Board (or a duly authorized committee of the Board), will be payable monthly in arrears on the final day of each month, beginning August 31, 2021. During the year ended December 31, 2022, the Board declared and paid the Company aggregate dividends on the shares of Series A Preferred Stock of approximately $3.9 million, respectively. The Board of Directors had not declared any Series A Preferred Stock dividends beginning October 2022 through the date of this report, as such the Company has accumulated approximately $1.7 million of dividends in arrears on the Series A Preferred Stock through December 31, 2022. An additional $5.2 million of dividends in arrears on the Series A Preferred Stock has been accumulated for a total of approximately $6.9 million in dividend in arrears.

20

The Company’s Series B Preferred Stock includes a 10% accruing dividend compounded daily for 12 months from the original issue date of July 20, 2022 that may be paid in cash or stock at the Company’s option at the earlier of (i) the date the Series B Preferred Stock is converted, or (ii) the Series B Dividend Termination Date. On August 11, 2023, Soluna Holdings, Inc. (the “Company”) paid a mandatory dividend on its outstanding Series B Convertible Preferred Stock in the amount of approximately $657 thousand. Pursuant to the Certificate of Designation for the Series B Stock, the Company had the option to pay the dividend in cash or shares of Common Stock. Pursuant to a Dividend Payment Agreement, the Company and the holder of the Series B Stock agreed to satisfy the payment of the dividend through the issuance of 44,000 shares of its Common Stock and 70,300 prefunded warrants (the “Prefunded Warrants”).

Each Pre-Funded Warrant has been funded to the amount of $.19999, with $0.00001 per share of common stock payable upon exercise, is immediately exercisable, may be exercised at any time until exercised in full and is subject to customary adjustments. The Pre-Funded Warrants may not be exercised if the aggregate number of shares of the Company’s common stock beneficially owned by the holder (together with her affiliates) would exceed 4.99% of the Company’s outstanding Common Stock immediately after exercise. However, the holder may increase (upon 61 days’ prior notice from the holder to the Company) or decrease such percentages, provided that in no event such percentage exceeds 4.99%.

Reservation of Shares

The Company had reserved common shares for future issuance as follows as of September 30, 2023:

Stock options outstanding (1)	52,392
Restricted stock units outstanding	11,907
Warrants outstanding (1)	1,230,130
Common stock available for future equity awards or issuance of options (1)	412,337
Number of common shares reserved	1,706,766

(1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for-25 that became effective October 13, 2023. See Note 2, “Basis of Presentation,” for details.

The Company also notes that as of September 30, 2023, there are 1,100,839 Series A preferred stock available for future equity awards under the 2021 Plan.

Income (Loss) per Share

The Company computes basic income (loss) per common share by dividing net income (loss) by the weighted average number of common shares outstanding during the reporting period. Diluted income (loss) per share reflects the potential dilution, if any, computed by dividing income (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.

The Company notes as continuing operations was in a net loss for the three and nine months ended September 30, 2023 and 2022, as such basic and diluted earnings per share is the same balance as continuing operations acts as the control amount in which would cause antidilution. Not included in the computation of earnings per share, assuming dilution, for the three and nine months ended September 30, 2023, were options to purchase 52,392 shares of the Company’s common stock, 11,907 outstanding restricted stock units, and 1,230,130 outstanding warrants not exercised. These potentially dilutive items were excluded because the calculation of incremental shares resulted in an anti-dilutive effect.

Not included in the computation of earnings per share, assuming dilution, for the three and nine months ended September 30, 2022, were options to purchase up to 32,493 shares of the Company’s common stock, 32,292 outstanding restricted stock units, outstanding warrants to purchase up to 303,312 shares of common stock, and shares of common stock issuable upon the conversion of a portion of the October Secured Notes pursuant to the Addendum. These potentially dilutive items were excluded because the calculation of incremental shares resulted in an anti-dilutive effect.

Contingencies:

Spring Lane Capital Contingency

The Company has a potential contingency associated with an agreement with Spring Lane of up to $250 thousand which would be reduced by a proportion of funding received from Spring Lane up to the $35.0 million aggregate contribution cap. The Company considers the probability of a payment for the contingency to be remote.

Legal

We are subject to legal proceedings, claims and liabilities which arise in the ordinary course of business. When applicable, we accrue for losses associated with legal claims when such losses are probable and can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. Legal fees are charged to expense as they are incurred.

The Company has been named as a party in the December 19, 2019 United States Environmental Protection Agency (“EPA”) Demand Letter regarding the Malta Rocket Fuel Area Superfund Site (“Site”) located in Malta and Stillwater, New York in connection with an alleged release of hazardous materials into the environment. The EPA is seeking reimbursement of response costs from all named parties in the amount of approximately $358 thousand plus interest in connection with the investigation and disposal activities associated with the various drum caches discovered at the Site, issuance of the Explanation of Significant Differences (“ESD”) of the Site, and implementation of the work contemplated by the ESD. The Company considers the likelihood of a material adverse outcome to be remote and does not currently anticipate that any expense or liability it may incur as a result of these matters in the future will be material to the Company’s financial condition.

NYDIG filed a complaint against a subsidiary of Company, Soluna MC Borrowing 2021-1, LLC (“Borrower”) and Soluna MC, LLC, as Guarantor (“Guarantor”), and together with Borrower, (“NYDIG Defendants”) in Marshall Circuit Court of the Commonwealth of Kentucky on December 29, 2022 regarding a series of loans made by NYDIG to Borrower pursuant to a master equipment finance agreement that were secured by certain assets of Borrower and guaranteed by Guarantor pursuant to a written guaranty agreement executed by Guarantor. The Court issued on February 15, 2023 an agreed order granting NYDIG’s motion for writ of possession which, among other things, ordered parties to provide NYDIG access to the collateral described therein and preserved the rights of NYDIG to pursue a deficiency judgment against the NYDIG Defendants. Also on February 15, 2023, the NYDIG Defendants filed their answer and affirmative defenses in this proceeding. The NYDIG Defendants believe that NYDIG has liquidated some of the collateral securing the loans and anticipate that NYDIG will complete the liquidation of collateral and continue to prosecute the complaint to obtain a judgment against the NYDIG Defendants. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The NYDIG Defendants noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the NYDIG Defendants are currently disputing.

In September 2023, Atlas Technology Group LLC (“Atlas”) filed a complaint against Soluna MC LLC (formerly EcoChain Block LLC) (“Soluna MC”), Soluna Computing, Inc., and Soluna Holdings, Inc. (collectively, the “Atlas Defendants”) in the Supreme Court of the State of New York, County of New York regarding a co-location services agreement between Soluna MC and Atlas.  Atlas alleges that the termination of such agreement by Soluna MC was a breach and asserts various claims, including breach of contract and the return of pre-paid fees. The claim requests a judgement against the Atlas Defendants for the return of pre-paid fees of approximately $464 thousand and additional damages to be determined at trial of not less than $7.9 million, and reimbursement of costs including legal fees and other costs. The complaint also contains references to alter ego liability and piercing the corporate veil.  The Atlas Defendants believes they have substantial factual and legal defenses to these claims and intend to defend the claims vigorously.

The referenced pre-paid fees of approximately $464 thousand have been reported in previous filings on Soluna MC’s balance sheet. No reserves have been established for any other claims asserted in such complaint.

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 thousand to secure the intercompany amounts due to the Company from MeOH Power, Inc. upon the deconsolidation of MeOH Power, Inc. Interest accrues on the Note at the Prime Rate in effect on the first business day of the month, as published in the Wall Street Journal. At the Company’s option, all or part of the principal and interest due on this Note may be converted to shares of common stock of MeOH Power, Inc. at a rate of $0.07 per share.

Legal Services

During the three and nine months ended September 30, 2023, the Company incurred $1 thousand and $1 thousand, respectively, to Couch White, LLP for legal services associated with contract review. During the three and nine months ended September 30, 2022, the Company incurred $1 thousand and $2 thousand, respectively. A partner at Couch White, LLP is an immediate family member of one of our Directors.

HEL Transactions

As discussed above, on October 29, 2021, the Company 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, (B) SHI issued to HEL the Termination Shares, and (C) HEL and SHI entered into an Amended and Restated Contingent Rights Agreement that, among other things, amended the existing Contingent Rights Agreement by and between HEL and SHI, dated January 13, 2020, to provide SHI the right to invest directly in certain cryptocurrency mining opportunities being pursued by HEL. SHI filed a registration statement with the SEC to register the resale of the Termination Shares on February 14, 2022.

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 Merger Shares were issued on May 26, 2023 and 39,600 Merger Shares were issued on October 10, 2023. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 59,400 Merger Shares, a total of 59,400 Merger Shares remain available for possible issuance pursuant to the terms of the Merger Agreement.

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.

Four of the Company’s directors have various affiliations with HEL.

Michael Toporek, the former Chief Executive Officer, and current Executive Director of the Company, 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.

24

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 nine months ended September 30, 2023 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.

The Company’s investment in HEL was initially carried at the cost of investment and was $750 thousand. Based on evaluation of projections for the Company’s investment in HEL, the Company fully impaired the equity investment of $750 thousand as of December 31, 2022, writing it down to $0.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of September 30, 2023 and December 31, 2022. The Company may enter into additional transactions with HEL in the future.

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.

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.

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.

During the three months ended September 30, 2023, the Company did not issue any equity awards under its 2021 or 2023 Plans.

During the nine months ended September 30, 2023, the Company awarded 20,000 restricted stock units under the 2021 Plan, valued at $7.465 per share based on the closing market price of the Company’s common stock on the date of the grant. The restricted stock units vested during May 2023.

13. Effect of Recent Accounting Updates

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 in fiscal year 2023 and properly record and disclose in relation to Topic 326.

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 its adoption of new accounting pronouncements or changes to its significant accounting policies that were disclosed in its condensed unaudited consolidated financial statements for the three and nine months ended September 30, 2023.

14. Discontinued Operations

As described in Note 1, the Company entered into a Stock Purchase Agreement with Purchaser, pursuant to which the Company sold on April 11, 2022 all of the issued and outstanding shares of capital stock of its wholly-owned subsidiary, MTI Instruments for approximately $9.0 million in cash, net of transaction costs. For fiscal year 2022 and 2023, our Instrumentation business segment was classified as discontinued operations in our financial statements for all periods presented. The Company incurred approximately a $7.5 million pretax gain on sale of MTI Instruments for the year ended December 31, 2022, in which they did not receive until the second quarter of fiscal year 2022. The Company’s condensed consolidated balance sheets and condensed consolidated statements of operations report discontinued operations separate from continuing operations. The Company’s condensed consolidated statements of equity and statements of cash flows combine continuing and discontinued operations.

MTI Instruments Sale

As described in Note 1, the Company entered into a Stock Purchase Agreement with Purchaser, pursuant to which the Company sold on April 11, 2022 all of the issued and outstanding shares of capital stock of our wholly-owned subsidiary, MTI Instruments for an all-cash purchase price of $10.75 million, subject to working capital and certain other adjustments as set forth in the Stock Purchase Agreement. The purchase price did not include specified debt of MTI Instruments, which is the responsibility of the Company. This debt was transferred to the Purchaser at the date of Sale and is included in the closing balance sheet as shown below, which resulted in a reduction in the consideration payable to the Company.

The following table presents the gain associated with the Sale that was reported within the 2022 Annual Report.

15. PROJECT MARIE

As previously disclosed in Footnotes 4 and 8, 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 million became due immediately and the Borrower was to bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. As of September 30, 2023, the Company reduced the outstanding debt by the repossessed collateralized assets net book value of $3.4 million less accrued interest that was paid off first when the collateral was repossessed of approximately $560 thousand and legal fees of approximately $251 thousand, reducing the debt outstanding to approximately $8.0 million as of September 30, 2023. Also, as the Company was not able to obtain a waiver, the outstanding deferred financing costs were written off. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the quarter. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing. As of September 30, 2023 and December 31, 2022, the Borrower had incurred accrued interest and penalty of approximately $810 thousand and $274 thousand.

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 million in which were written off the Company’s books for the nine months ended September 30, 2023, with an offset accrued interest to date when repossessed, a loss on sale of fixed assets, and to the outstanding loan. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. In a related development, also on February 23, 2023, the Borrower received a notice of termination of the Management and Hosting Services Agreement with CC Metals and Alloys, LLC. As a result of this action and certain other characteristics of the facility, the Company elected to shut down the Marie facility. The Company believes it will maximize its profits and return on assets by concentrating its personnel and capital on its Dorothy Facility.

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 million of equipment and leasehold approvements associated with Project Marie that were not attached with the repossession of NYDIG collateralized assets were impaired as of the year-ended December 31, 2022.

For the three and nine months ended September 30, 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.

29

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:

16. VARIABLE INTEREST ENTITY

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 million to fund certain projects to develop green data centers co-located with renewable energy assets (the “Spring Lane Commitment”). We anticipate that these capital contributions, once deployed into the projects, will help develop up to three behind-the-meter (BTM) projects designed to convert wasted renewable energy into clean computing services such as Bitcoin mining and artificial intelligence. The Bilateral Contribution Agreement outlines the framework for the Spring Lane Commitment; however, neither we nor Spring Lane are obligated to complete any projects under such agreement and any actual capital contributions are subject to various conditions precedent, including the receipt of requisite lender and other consents, acceptance by Spring Lane of specific projects and negotiations of agreements regarding those projects, including milestones and structure. In partial consideration of the amendment to the October Secured Notes discussed above, the investors agreed to release certain collateral covered by their security agreement to permit the Company to proceed forward with the initial phase of Project Dorothy, which we expect to be partially funded by Spring Lane, which the Company expects to complete in the near future.

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 the first 25 MW of 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 million to DVSL (the “Company Commitment”), and on August 5, 2022, the Company was deemed to have contributed approximately $8.1 million, through payment of capital expenditures and development costs made on behalf of DVSL by the Company prior to August 5, 2022. Further under the Agreement, Spring Lane committed to a capital contribution of up to $12.5 million to DVSL (the “Spring Lane Dorothy Commitment”), and as of December 31, 2022, Spring Lane contributed approximately $4.8 million. Under the Dorothy Contribution Agreement, the Company and Spring Lane have committed to make subsequent contributions, up to their respective Company Commitment and Spring Lane Dorothy Commitment amounts, on a pro rata basis, upon receipt of a contribution request from DVSL, as set forth in the Dorothy Contribution Agreement and subject to the satisfaction of certain conditions described therein. The proceeds of any subsequent commitments will be applied to pay project costs in accordance with the project budget.

30

In exchange for their contributions, the Company and Spring Lane were issued 67.8% and 32.2% of the Class B Membership Interests in DVSL, respectively, and were admitted as Class B members of DVSL. Further pursuant to the Agreement, DVSL issued 100% of its Class A Membership Interests to Devco. The Dorothy Contribution Agreement contains customary indemnification provisions, liquidation provisions and governance provisions with respect to DVSL. The Parties also entered into an Amended and Restated Limited Liability Company Agreement of DVSL providing for the governance of DVSL.

Soluna evaluated this legal entity under ASC 810, Consolidations and determined that DVSL is a variable interest entity that should be consolidated into Soluna, with a non-controlling interest recorded to account for Spring Lane’s equity ownership of the Company. Soluna has a variable interest in DVSL. The entity was designed by Soluna to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in Soluna, through its equity interest in DVSL, absorbing operational risk that the entity was created to create and distribute, resulting in Soluna having a variable interest in DVSL.

On March 10, 2023, the Company along with Devco, and Soluna DVSL ComputeCo, LLC, a Delaware limited liability company (the “Project Company”) entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”) with Soluna SLC Fund I Projects Holdco, LLC, a Delaware limited liability company (“Spring Lane”) that is wholly owned indirectly by Spring Lane Management LLC. The Project Company is constructing a modular data center with a peak demand of 25 megawatts (the “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 $7,500,000 (the “Sale”). After giving effect to the Sale, the Company owned 6,790,537 Class B Membership Interests (constituting 14.6% of the Class B Membership Interests) and Spring Lane owns 39,791,988 Class B Membership Interests (constituting 85.4% of the Class B Membership Interests). The cash portion of the purchase price paid by Spring Lane to the Company was $5,770,065, which represented the purchase price of $7,500,000 less the Company’s pro rata share of certain contributions funded entirely by Spring Lane in the earlier portion of this series of transactions occurring during February 2023 and March 2023. As a further part of these transactions, the parties agreed that from January 1, 2023 onwards, Soluna would bear only 14.6% of the costs relating to the construction and operation of the Dorothy Phase 1A Facility, compared to its 67.8% share until that time, including during the calendar year 2022. After Spring Lane Capital realizes an 18% 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.

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”), an amendment and restatement of the Third Amended and Restated Limited Liability Company Agreement of the Project Company dated as of March 3, 2023, and (b) the Amended and Restated Contribution Agreement, dated as of March 10, 2023 (the “A&R Contribution Agreement”), an amendment and restatement of the Contribution Agreement dated as of August 5, 2022. The Fourth A&R LLCA provides for certain updates in respect of Spring Lane’s majority ownership. The A&R Contribution Agreement reflects updated pro rata member funding percentages as a result of the Sale as well as updated contribution caps for each of the Company and Spring Lane.

As of January 1, 2023, there were no changes in the Limited Liability Agreement of the Company other than those related to incorporating the new investment and the purpose and design of the Company has not changed. 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.

Effective, January 1, 2023, the Company’s ownership in DVSL was reduced from 67.8% to 14.6%; see above for details.

On May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DV”) completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC, (“Navitas”) organized by Navitas Global, to complete the second phase of the Dorothy Project (“Dorothy 1B”). Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which 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 $4,500,000 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 $7,596,970 and receipt of an additional 7,597 Membership Interests, for a total of 12,097 Membership Interests and 49% ownership of the Company, and (ii) Soluna’s additional capital contribution of $1,340,000 and receipt of an additional 1,340 Membership Interests, for a total of 12,590 Membership Interests and 51% ownership of the Company, and (b) describe the respective rights and obligations of the Members and the management of the Company.

Soluna evaluated this legal entity under ASC 810, Consolidations and determined that DV is a variable interest entity that should be consolidated into Soluna, with a non-controlling interest recorded to account for Navita’s equity ownership of the Company. Soluna has a variable interest in DV. The entity was designed by Soluna to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in Soluna, through its equity interest in DV, absorbing operational risk that the entity was created to create and distribute, resulting in Soluna having a variable interest in DV.

DV is a variable interest entity of Soluna due to DV being structured with non-substantive voting rights. This is due to two factors being met as outlined in ASC 810-10-15-14 that require the Variable Interest Entity model to be followed.

a.	The voting rights of Soluna are not proportional to their obligation to absorb the expected losses of the legal entity. Soluna gave Navitas veto rights over significant decisions, which results in Soluna having fewer voting rights than their obligation to absorb the expected losses of the legal entity.
b.	Substantially all of DV’s activities are conducted on behalf of Soluna, who has disproportionally fewer voting rights.

Also, Soluna is the primary beneficiary due to having the power to direct the activities of DV that most significantly impact the performance of the Company due to its role as the manager handling the day-to-day activities of DV as well as majority ownership of and has the obligation to absorb losses or gains of DV that could be significant to Soluna.

Accordingly, the accounts of DV are consolidated in the accompanying unaudited condensed financial statements

17. Segment Information

The Company applies ASC 280, Segment Reporting, in determining its reportable segments. The Company has two reportable segments: Cryptocurrency Mining and Data Hosting. The Company notes that previously there was an additional segment: Test and Measurement Instrumentation, however as discussed in Note 1, the Company sold MTI Instruments in April 2022, and therefore has classified as discontinued operations. The guidance requires that segment disclosures present the measure(s) used by the Chief Operating Decision Maker (“CODM”) to decide how to allocate resources and for purposes of assessing such segments’ performance. The Company’s CODM is comprised of several members of its executive management team who use revenue and cost of revenues of both reporting segments to assess the performance of the business of our reportable operating segments.

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.

For the three months ended September 30, 2023 and 2022, approximately 0% and 4% of the Company’s cryptocurrency mining revenue was generated from Project Edith (data center located in Wenatchee, Washington), 0% and 37% from Project Marie, 3% and 59% from Project Sophie (data center located in Murray, Kentucky), and 97% and 0% from Project Dorothy (data center located in Texas), respectively. 0% and 100% of the Company’s data center hosting revenue was generated from Project Marie from hosting with customers for the three months ended September 30, 2023 and 2022, 25% and 0% of the data hosting revenue for three months ended September 30, 2023 and 2022 was generated from Project Sophie, and 75% and 0% of the data hosting revenue for the three months ended September 30, 2023 and 2022 was generated from Project Dorothy (data center located in Texas).

For the nine months ended September 30, 2023 and 2022, approximately 0% and 6% of the Company’s cryptocurrency mining revenue was generated from Project Edith (data center located in Wenatchee, Washington), 14% and 41% from Project Marie, and 54% and 53% from Project Sophie (data center located in Murray, Kentucky) and 32% and 0% from Project Dorothy (data center located in Texas), respectively. 5% and 100% of the Company’s data center hosting revenue was generated from Project Marie from hosting with customers for the nine months ended September 30, 2023 and 2022, 31% and 0% of the data hosting revenue for nine months ended September 30, 2023 and 2022 was generated from Project Sophie, and 64% and 0% of the data hosting revenue for the nine months ended September 30, 2023 and 2022 was generated from Project Dorothy (data center located in Texas) for the nine months ended September 30, 2023 and 2022.

The Company evaluates performance based on profit or loss from operations before income taxes, accounting changes, items management does not deem relevant to segment performance, and interest income and expense. Inter-segment sales and expenses are not significant. Non-cash items of depreciation and amortization are included within both costs of sales and selling, general and administrative expenses.

18. Subsequent Events

Reverse Stock Split

On October 11, 2023, the Company filed a 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. The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023. The reverse stock split was approved by the Board of Directors and by shareholders at the annual meeting of the stockholders on June 29, 2023. At the effective time, 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 Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole share.

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 per share (the “Series B Preferred Stock”), may be converted to Common Stock. The total number of shares of Series B Preferred Stock of the Company authorized for issuance remained at 187,500.

Please see “Statement Concerning Forward-Looking Statements” below.

Overview

Our mission is to facilitate the integration of more renewable energy into the grid by leveraging computing facilities. Operating under our wholly-owned subsidiary, Soluna Computing, Inc. (“SCI”), we design, develop, and manage flexible data centers to run compute-intensive applications including cryptocurrency mining, and artificial intelligence. Our specialized data centers are co-located with curtailed – underutilized – renewable energy power plants.

We provide a cost-effective alternative to battery storage or transmission lines to grid operators and independent power producers. The traditional approach to storing excess power or transferring it to distant locations is expensive and faces significant logistical challenges. Co-located renewables plus data centers offer a solution, a symbiotic relationship by deploying data centers that use the surplus energy for computing activities, providing an immediate off-take agreement that essentially acts as a ‘digital battery.’ In addition, our data centers can dynamically adjust their energy consumption in real time, aiding grid operators in balancing supply and demand during energy scarcity.

Presently, we operate at a 75-megawatt capacity across two sites, namely, Project Sophie and Project Dorothy. We have over 2 Gigawatts (“GW”) in our long-term pipeline with some of the country’s top renewable energy power producers. We also have 216 MW between two new data center projects namely: Project Dorothy 2, for 50 MW, and Project Kati for 166 MWs. Projects Marie and Edith have been decommissioned or exited, as discussed further below.

Our facilities have the ability to dynamically adjust their energy consumption in real time. When energy is scarce, the data centers can rapidly reduce their consumption, making it easier for the grid to balance supply and demand. This unique feature enables a more seamless integration of additional renewable energy sources into the grid while also propping up the economic profile of existing renewable power plants. The result is an increase in the overall renewable fraction on the grid, pushing us closer to a sustainable energy future. This is a win-win scenario, turning excess power into an asset rather than a liability, while also advancing our transition toward a more sustainable and efficient energy ecosystem.

Achieving our mission takes a multi-disciplinary skill set. A nuanced grasp of complex energy regulatory regimes shapes the development of our behind-the-meter data centers, facilitating compliance with grid and regulatory standards. Expertise in constructing and operating expansive facilities in isolated locations ensures the efficiency and reliability of our renewable energy plants and data centers. In the realm of computer science, our know-how enables us to refine data processing and cryptocurrency mining activities for the most effective use of energy. Operational excellence sets us apart, as does our ability to negotiate complex power contracts that provide both low-carbon and cost-effective energy. These factors collectively are our strategic differentiation, allowing us to turn excess energy into a valuable asset while enhancing the sustainability of the broader energy ecosystem.

Curtailed energy, defined as energy priced at zero or negative rates, is an increasingly acute issue plaguing power producers, particularly in Texas. It is the primary reason why many renewable power plants fail to achieve their base-case financial returns. Our Dorothy site stands as our inaugural venture aimed at consuming this otherwise unutilized energy. The consumption of this curtailed energy offers multiple benefits: First, it improves the economics for the power plant, making the construction of wind and solar facilities in the USA more financially viable. Second, this energy, which otherwise would go to waste, is put to productive use, making it a truly additional resource. Third, it provides a source of zero-carbon compute power, which otherwise would have been generated from higher carbon sources, thereby reducing the overall carbon footprint of Bitcoin mining. This innovative approach to utilizing curtailed energy not only offers a solution to a pressing industry problem but also serves as a key aspect of our strategic differentiation.

The Company currently earns revenue by mining cryptocurrencies and providing hosting services to Bitcoin Mining companies at our data centers. In the future, we plan to host AI customers at our data centers. See below for further details on our project sites.

Project Edith

The Edith project is a project permitted to consume up to 3.3 MegaWatts located in Wenatchee, Washington. The data center was acquired from the estate of the GigaWatt bankruptcy in May 2020. The project operates in a district with increasing power rates. In the first quarter of 2022, the ETH (“Ethereum”) foundation made it clear that the merge to proof-of-stake was happening and graphics processing unit (“GPU”) mining was going to be challenged going forward. In the early summer of 2022, Soluna began to seek a buyer for the assets. Soluna ultimately sold the GPU mining assets and other mining equipment in September 2022 for $790 thousand. Soluna has committed to providing certain facilities contracts at cost plus a markup to facilitate the continued operations for the mining assets for the new ownership. Within Notes receivable on the condensed unaudited consolidated financial statements is a secured note receivable for $193 thousand, in which as of September 30, 2023 is in default. This note receivable is secured by assets, the value of which is sufficient to cover the note.

Project Marie

Project Marie was Soluna’s 20 MW co-location facility based in Kentucky. This facility was Soluna’s first project in Kentucky, prior to building the Sophie greenfield project. The site is powered by the Tennessee Valley Authority (“TVA”) grid and was designed to operate 24/7 less mandatory TVA curtailment windows.

On December 30, 2021, Soluna MC Borrowing 2021-1 LLC (the “Borrower”), an indirect wholly owned subsidiary of the Company entered into a Master Equipment Finance Agreement (the “MEFA”) with NYDIG ABL LLC (“NYDIG”) as lender, servicer and collateral agent (the “NYDIG facility”). The Master Agreement outlined the framework for a financing up to approximately $14.4 million in aggregate equipment financing.

In January 2022, Soluna began investing capital into Project Marie to upgrade the facility to support 20 MW of power consumption and create power efficiencies in the main leased building. These upgrades were completed in February of 2022. In January, Soluna completed the roll out of legacy hosting customers at the facility to be replaced with proprietary mining equipment.

In March and April of 2022, the facility experienced several unplanned outages due to issues with electrical infrastructure owned by CCMA. Despite these setbacks, the facility was able to recover and continue to run at a steady hashrate throughout the course of the year. When the Bitcoin downturn hit, the Marie facility took initiative to ensure maximum efficiency of the miner inventory and also took action to reduce site-level expenses.

Project Marie power was negatively impacted by increased Financial Conduit Authority (“FCA”) changes in late summer which were at levels not seen in many years. To further reduce risk to contribution margin, the company began contract negotiations with the 10 MW hosting customer at the site whose renewal was due in September. These negotiations resulted in a more favorable fee structure that positioned the company to better navigate the FCA volatility and the broader Bitcoin economics.

36

By September 2022, the decline in the price of Bitcoin caused the cashflow from Marie to decline to a level insufficient to service the NYDIG loan. After discussions with NYDIG, two separate monthly waivers of payments for September and October 2022 were agreed. By November 2022, the Borrower failed to make its payment, and on December 20, 2022, the Borrower received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG with respect to the MEFA, by and between Borrower and NYDIG. 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 guarantee, collateral agreement or other support agreement with or for the benefit of NYDIG. Borrower entered into a dialogue with NYDIG to resolve the matters set forth in the NYDIG Notice but was unsuccessful.

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.

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. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. In a related development, also on February 23, 2023, the Borrower received a notice of termination of the Management and Hosting Services Agreement with CC Metals and Alloys, LLC. As a result of this action and certain other characteristics of the facility, the Company shut down the Marie facility, and impaired certain property, plant, and equipment assets owned by the Marie facility.

In the third quarter of fiscal year 2023, Project Marie sold the remaining Tesseracks (mobile, Bitcoin Mining Equipment), in which were not included as part of the collateralized equipment for NYDIG. Project Marie received proceeds from the sale of the Tesseracks of $320 thousand in which included a note receivable of $240 thousand that is outstanding as of September 30, 2023.

Project Sophie

Project Sophie is Soluna’s 25 MW modular data center based in Kentucky. This facility is the first site based on Soluna’s modular design, electrical design, and powered by its proprietary software Maestro OS (™). The site is powered by the TVA grid and is designed to operate during off-peak hours to help Western Kentucky Rural Electric Cooperative (“WKRECC”) manage its excess energy consumption.

By April 8, 2022, older machines (Bitmain S9s) at Sophie were replaced with newer models growing the hashrate and a power usage effectiveness and consuming over 20 MW of energy. In May of 2022, upgraded the network infrastructure on the site and in June and July of 2022, installed new Bitmain S19s and replacing S9 machines, and as a result, the site significantly exceeded previous mining hash rates. Project Sophie has also hosted a series of curtailment and MaestroOS control system, our proprietary load monitoring management system, demonstrations with leading renewable energy companies and capital providers, further enhancing the site’s performance.

On April 6, 2023 and June 28, 2023, Project Sophie entered into hosting contracts with Bitcoin miners, which shifted Project Sophie’s business model at the modular data center from proprietary mining to data hosting. Subsequent to September 30, 2023, Project Sophie has entered into new hosting contracts with various customers.

We are currently selling existing Bitcoin miners at the site and redeploying capital, in which approximately $220 thousand is included within Equipment held for sale as of September 30, 2023.

As of the date of the condensed unaudited financial statements, Project Sophie has deployed more than 8,000 machines for its hosting customer filling 25 MW of capacity. In addition, Project Sophie has signed new hosting term sheets for 15 MW. The new hosting deals included an expansion of the relationship with Compass Mining and two customers including Bit Digital (Nasdaq: BTBT). Project Sophie’s existing customer is beginning its planned ramp down in fourth quarter of fiscal 2023. The new contracts are planned to bring in more profitability for us.

Project Dorothy

The Dorothy Project is a 100 MW Soluna modular data center co-located at the Briscoe Wind Farm in Silverton, Texas. It was acquired as part of the merger with Soluna Callisto in October 2021, discussed in further details on Footnote 5 on the condensed unaudited consolidated financial statements. The initial 50MW phase (“Phase 1”) of the project includes 44 modular data center buildings in two sub-phases, Dorothy 1A and Dorothy 1B. Each of these sub-phases is 25 MW each. Dorothy is the second modular data center built using Soluna’s proprietary design and software. The facility is designed to purchase the excess electricity from the wind farm and the grid. It incorporates learnings and enhancements from Sophie project.

As of the date of these condensed unaudited financial statements, Phase 1 has been completely energized.

Permitting, Energization, Deployment and Construction:

In March 2022, Soluna began site level construction via an early access agreement with the landowner and Briscoe Wind Farm, LLC., to place the concrete pad and erection of the site’s main warehouse. In April of 2022, the procurement of internet service providers began. By May 2022, the company began erecting the prefabricated modular data center buildings and trenching for underground electrical conduits.

On June 15, 2022, the Electric Reliability Council of Texas (“ERCOT”), the Texas independent system operator, formed a new taskforce, Large Flexible Load Interconnection Taskforce (“LTLTF” of “LFL”) to deal with the overwhelming increase in new load interconnection requests related to Bitcoin Mining. The new task force’s charter focused on studying the systems impact of these data centers and to establish a new interim process for approval. The new process included the addition of new technical studies and modeling to ensure the reliability of the electrical system. Briscoe, Oncor and Soluna collaborated on completing the required technical studies throughout the summer and early fall of 2022.

On October 31, 2022, after the completion of required studies, the Briscoe Wind Farm submitted a revised Resource Asset Registration Forms (“RARF”) to ERCOT requesting the addition of the Dorothy Project as a 100 MW behind-the-meter load and to initiate the modeling process. On December 8, 2022, the Briscoe/Soluna project was approved by the ERCOT modeling team. On December 19, 2022, all required studies were approved and the Dorothy Project received a “Met Planning” approval from ERCOT LFL.

While these ERCOT approvals were being obtained, through the summer and fall of 2022, Soluna continued the construction of Dorothy erecting more buildings, installing power infrastructure, completing the warehouse and office buildings, including ancillary HVAC and power. From September to December 2022, all mechanical and electrical construction was completed for Dorothy 1A. On October 15, 2022, Dorothy 1B’s construction was officially paused. In March 2023, the data center’s substation interconnection was completed, and Dorothy 1B’s construction was resumed and the site’s network and Supervisory Control and Data Acquisition systems were installed.

On April 20, 2023, after the review of the Briscoe Wind Farm’s RARF (see above), ERCOT approved the energizing of the first 50 MW of Project Dorothy as a behind-the-meter load; on April 27, 2023, the Company signed a 5 MW 2-year hosting deal with Compass Mining at Dorothy 1A; and on May 10, 2023, the Company signed a 20 MW 2-years hosting agreement with another strategic hosting partner at Dorothy 1A. Since these important agreements, the Company completed the deployment of both contracts deploying over 7,500 machines to site as of September 30, 2023.

On May 9, 2023, having consummated a partnership with Navitas Global (see below) for Project Dorothy 1B, started working on the completion of the construction and energization of this portion of the project. In June 2023, the Company purchased 8,378 Bitmain Antminer S19s, S19j Pro and S19j Pro+ machines for Project Dorothy 1B. The purchase is estimated to result in 868 PH/s of hashrate with an average efficiency of 29.9 J/TH and at a cost of $10.59 $/TH. As of September 30, 2023, approximately 8,000 of the miners have been deployed.

Project-level Financing (Dorothy 1A and Dorothy 1B):

On April 22, 2022, SCI signed definitive agreements with funds managed by Spring Lane Capital (“SLC”) to provide a $35 million pool of capital for financing Soluna projects co-located with renewable energy projects. At least $12.5 million of the pool was earmarked for the Dorothy Project. In July 2022, Soluna began drawing down on the SLC capital to finance Dorothy construction and return capital to the Company for past funding. In exchange for SLC’s contributions, the Company and Spring Lane were issued approximately 68% and 32% of the Class B Membership Interests in Soluna DVSL ComputeCo, LLC (“DVSL”). The Company consolidated the accounts of DVSL, a Variable Interest Entity (“VIE”), as of December 31, 2022 and September 30, 2023.

38

On March 10, 2023, SCI completed the final tranche of a series of project-level agreements for $7.5 million of capital to fund the first 25 MW of the Dorothy Facility and corporate expenses from funds managed by SLC. This additional capital will be used to help complete the substation interconnection and the final stages of the Dorothy Facility, and corporate operations of Soluna. SLC has been a strategic partner for Soluna at the project and corporate levels of the business since 2022. In this series of transactions, SLC has increased its stake in DVSL from approximately 32% to 85% and has in turn reduced SHI’s ownership from 68% to 15%. After SLC realizes an 18% Internal Rate of Return hurdle on its investments, Soluna retains the right to 50% of the profits on Soluna DVSL ComputeCo.

The second 25 MW being developed as part of the Dorothy Facility, the ownership of which is held within Soluna DV ComputeCo, LLC (“DV”). On May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DV”) completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC, (“Navitas”) organized by Navitas Global, to complete the second phase of the Dorothy Project (“Dorothy 1B”). The proprietary-mining focused joint venture brings Navitas into Project Dorothy 1B as an investor and equity partner. Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which 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 $7.6 million and receipt of an additional 7,597 Membership Interests, for a total of 12,097 Membership Interests and 49% ownership of the Company, and (ii) Soluna’s additional capital contribution of $1.3 million and receipt of an additional 1,340 Membership Interests, for a total of 12,590 Membership Interests and 51% ownership of the Company, and (b) describe the respective rights and obligations of the Members and the management of the Company. The deal also includes a $2 million loan to complete construction. Soluna will provide operations and maintenance expertise and will remain an owner of 51% of Dorothy 1B. This partnership is a capstone to the recent deals at Dorothy 1A and Project Sophie, in which will help put the company on a positive trajectory.

Operating Definitive Agreements with Counter Parties:

Throughout 2022 SCI’s corporate development continued to negotiate the definitive documents with Golden Spread Electric Cooperative, Inc., a Texas cooperative corporation (“GSEC”) and Lighthouse Electric Cooperative, Inc., a Texas cooperative corporation (“LHEC”), Oncor Electric Delivery, LLC (“Oncor”) and Briscoe Wind Farm, LLC’s various sponsors and financing parties (“Briscoe”). These agreements were finalized in March 2023 (see below).

On March 2, 2023, Soluna DV Services, LLC, a Nevada limited liability company (“ServeCo”) and an indirect wholly-owned subsidiary of the Company, entered into a series of agreements with Briscoe, (b) GSEC, and (c) LHEC. All the agreements were effective as of February 24, 2023 (the “Effective Date”). The Company is developing a modular data center in phases (the “Dorothy Facility”). The two phases of the Dorothy Facility will have a peak demand of 50 megawatts, and if, upon mutual agreement, all four phases are completed, the data center will have an estimated peak demand of 150 megawatts. The Dorothy Facility will be located next to, and supplied energy from, Briscoe’s 150 MW wind farm located at or near Briscoe and Floyd Counties, Texas (the “Briscoe Wind Farm”). Under the agreements, LHEC and GSEC will supply the Dorothy Facility with energy from the Briscoe Wind Farm and the ERCOT market.

ServeCo and LHEC entered into an Agreement for Electric Service to Soluna DV Services, LLC (the “Retail Agreement”) for resale of energy supplied from the Briscoe Wind Farm and the ERCOT market delivered by GSEC for service to the energy load of the Dorothy Facility. As noted above, GSEC has by separate agreement arranged to purchase power at wholesale from Briscoe or to deliver and purchase power from the ERCOT market to serve LHEC with electric power and energy for resale to ServeCo for service to the Dorothy Facility. The initial term of the Retail Agreement is five years, with up to five extension terms of one year each unless terminated by LHEC or ServeCo.

ServeCo and Briscoe also entered into a Cooperation Agreement (the “Cooperation Agreement”), pursuant to which Briscoe and ServeCo agreed to certain rights, obligations, and restrictions with respect to the real property of the Dorothy Facility and the construction, interconnection, permitting, operation, maintenance, removal, and decommissioning of the Dorothy Facility and applicable credit support. Soluna DV ComputeCo, LLC, a Delaware limited liability company and an indirect wholly-owned subsidiary of the Company and Soluna DVSL ComputeCo, LLC, a Delaware limited liability company and an indirect wholly-owned subsidiary of the Company became parties to the Cooperation Agreement by each entering into a Joinder Agreement on the Effective Date. Unless terminated sooner in accordance with its terms, the term of the Cooperation Agreement is from the Effective Date until the expiration or termination of the Power Purchase Agreement, by and between Briscoe and GSEC, dated as of the Effective Date (the “PPA”).

39

ServeCo, Briscoe, LHEC, and GSEC also entered into a Performance and Net Energy Security Agreement (the “PSA”), pursuant to which ServeCo will provide certain credit support to LHEC in connection with its obligations under the Retail Agreement and the other transaction agreements. The PSA is effective on the Effective Date and will remain in effect for 18 months following the later of the termination of the Retail Agreement or the termination of the PPA.

On the Effective Date, ServeCo and Alice Fay Grabbe (“Owner”) entered into a Lease Agreement (the “Lease”) to lease certain real property located in Briscoe County, Texas for the Dorothy Facility. Unless terminated sooner in accordance with its terms, the initial term of the Lease is five years. The initial term of the Lease will automatically extend for five additional one-year periods, unless terminated by ServeCo or Owner.

Commercialization of Dorothy 1A:

On April 26, 2023, Soluna DVSL ComputeCo, LLC signed a 2-year 5 MW Master Enterprise Hosting Services Agreement with Compass Mining, Inc. (the “Compass MHSA”). Compass Mining is one of the world’s first and largest online marketplace for Bitcoin mining hardware and hosting. Through its network of partners with mining facilities located in the US and Canada, Compass facilitates both large and small miner deployments on behalf of its end-users. The customer has deployed approximately 1,600 miners at Dorothy 1A as of September 30, 2023

On May 5, 2023, Soluna DVSL ComputeCo, LLC signed a 2-year 20 MW Services Framework Agreement with a Strategic Hosting Partner. The customer deployed approximately 6,000 miners at Dorothy 1A as of September 30, 2023. This agreement puts the Dorothy 1A facility at full capacity.

The Company completed the installation at Dorothy 1A of the miners and fully ramped the site. Approximately 7,700 Bitcoin miners were deployed at Dorothy 1A resulting in an installed Hashrate of 950 PH/s. Dorothy 1A has consumed over 2,500 MWh of curtailed energy from the co-located power plant and achieved a power usage effectiveness (“PUE”) of 1.01.

Completion and Commercialization of Dorothy 1B

As of September 30, 2023, the building, infrastructure, and related equipment has been substantially completed at Dorothy 1B with approximately $12.3 million in service reflected in Property, Plant, Equipment. Over 7,920 Bitcoin miners were deployed at Dorothy 1B for proprietary mining resulting in an installed Hashrate of 816 PH/s. Dorothy 1B has consumed over 1,500 MWh of curtailed energy from the co-located power plant and achieved a power usage effectiveness (PUE) of 1.01.

Curtailment Mitigation

Our goal for Project Dorothy was to serve as a blueprint for a “digital battery” that efficiently monetizes wasted energy for our wind farm partner. In its initial six months of operation, Project Dorothy consumed over 4,000 MWh of curtailed energy, leading to improved financial viability for the power plant.

Project Dorothy 2 (and “Helix”)

We began to work on site design, request-for-proposals from EPCs, long lead electrical equipment for the next major phase of the Dorothy project. We also invited potential investors to tour Dorothy and present term sheets for investing in the project. The Company is now evaluating the best partner. The plan for Dorothy 2 will include a new element, the design and development of a new version of the Soluna Modular Data Center purpose-built for AI compute workloads. The new design, known internally as “Helix” plans to incorporate the latest in cooling, electrical, and space requirements from the burgeoning generative AI sector. We have held detailed discussions and design sessions with the leaders in computing infrastructure for AI and leveraging their years of experience developing scaled deployments of AI servers and networks. We believe the overwhelming unmet demand for power and computing space in the AI field will allow Soluna to transform its super low-cost computing infrastructure to meet AI’s exponentially growing needs. Soluna’s data centers and proprietary MaestroOS software have been designed for this opportunity since inception. As Soluna converts its asset base to be AI-centric, it expects to offer its AI customers purpose-built facilities powered by renewable energy at groundbreaking costs.

Project Kati

The Kati Project is a new 166 MW Soluna modular data center co-located with a 300 MW wind farm in Texas. On June 20, 2023, the Company announced the signing of a term sheet with a leading renewable energy development company based in the United States. Project Kati continues the development process, progressing through the first of three required ERCOT interconnection studies in the planning phase.

40

We have begun negotiating the power purchase agreements, land leases and other material project documents with the wind farm company. In addition, we have selected a qualified scheduling entity for the project. A request-for-proposal for long lead electrical equipment was launched and key infrastructure partners are being evaluated.

Discontinued Operations:

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% of the issued and outstanding common stock of MTI Instruments. On April 11, 2022, we consummated the sale of MTI Instruments, (‘the Sale”)., MTI Instruments ceased to be our wholly-owned subsidiary, and, as a result, we have exited the instruments business. As a result of the foregoing, the MTI Instruments business was reported as discontinued operations in the consolidated financial statements as of December 31, 2022 and prior periods within our Annual Report on Form 10-K for the year ended December 31, 2022, as was filed with the SEC on March 31, 2023.

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 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 the sale of approximately $7.8 million on is 2022 Annual Report.

Recent Developments and Trends

On October 11, 2023, the Company filed a 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 (the “Reverse Split”). The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023.

As a result of the Reverse Split, every 25 shares of the Company’s issued and outstanding common stock prior to the Reverse Split will automatically be converted into one new share of common stock, without any change in the par value per share. The Reverse Split reduced the number of shares of common stock issued and outstanding from approximately 37.3 million to approximately 1.5 million. The Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole share.

Cryptocurrency mining revenue: Cryptocurrency mining revenue consists of revenue recognized from SCI’s cryptocurrency mining operations.

Cryptocurrency mining revenue was approximately $1.8 million and $5.5 million for the three and nine months ended September 30, 2023 compared to $5.4 million and $20.7 million for the three and nine months ended September 30, 2022. We noted the significant decrease of approximately $3.6 million and $15.2 million mainly related to volume variances due to Project Marie operations being stopped in February 2023 in conjunction with the CCMA termination and NYDIG repossession of collateralized assets. The Company saw a $2.0 million and $7.8 million decline for the three and nine months ended September 30, 2023 due to Project Marie’s operations being ceased. In addition, the Company switched from a proprietary mining model at Project Sophie to data hosting in the middle of April 2023 with a 100% conversion to hosting by the end of September 2023. The switch to data hosting at Project Sophie created a $3.1 million and $8.0 million decrease in cryptocurrency mining revenue for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. Offsetting the decline in cryptocurrency mining revenue was the energization of miners at Soluna DV ComputeCo (“Dorothy 1B”) for approximately $1.7 million of revenue for the three and nine months ended September 30, 2023. The Company noted that the decrease was mainly affected by the number of machines being operated, however Bitcoin prices had fluctuated significantly between periods in which the average price of Bitcoin increased approximately 32% for the three months ended September 30, 2023 compared to three months ended September 30, 2022, whereas for the nine months ended September 30, 2023 the average Bitcoin price of Bitcoin had declined by approximately 17% compared to the nine months ended September 30, 2022.

Data hosting revenue: In August 2021, SCI began cryptocurrency hosting services in which SCI provides energized space and operating services to third-party mining companies who locate their mining hardware at one of SCI’s mining locations, in which they may receive a fee per miner installed, revenue share and if additional services are rendered, an additional service fee is charged to the outside parties. Data hosting revenue was approximately $4.0 million for the three months ended September 30, 2023 compared to $985 thousand for the three months ended September 30, 2022. Project Marie ceased operations in February 2023 causing a decline of approximately $984 thousand, however, this was offset in April 2023 when the Company switched from proprietary mining to data hosting at Project Sophie creating approximately $991 thousand in data hosting revenue. In addition, Dorothy 1A began energization in the second quarter of 2023, creating approximately $3.0 million in data hosting revenue, which is the significant driver in the increase in data hosting revenue. There was a significant increase of approximately $1.8 million in data hosting revenue for the nine months ended September 30, 2023 compared to September 30, 2022 primarily related energization of Project Dorothy 1A in the second quarter of 2023 creating approximately $3.5 million in data hosting revenue, in addition to Project Sophie switching from proprietary mining to data hosting in the second quarter of 2023, creating approximately a $1.7 million increase in data hosting revenue. The increase for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022 was offset with the shutdown of Project Marie operations in February 2023, as such, caused a decline in revenue of approximately $3.4 million for Project Marie.

Cost of cryptocurrency mining revenue, exclusive of depreciation: Cost of cryptocurrency mining revenue includes direct utility costs, site overhead expenses, depreciation expenses, as well as overhead costs that relate to the operations of SCI’s cryptocurrency mining facilities in Washington, Kentucky, and Texas. Going forward, cost of cryptocurrency revenue will include any additional SCI cryptocurrency mining facilities that are part of the Company’s future pipeline.

Cost of cryptocurrency mining revenue, exclusive of depreciation costs was approximately $1.0 million and $4.5 million for the three and nine months ended September 30, 2023 compared to $4.1 million and $11.1 million for the three and nine months ended September 30, 2022, respectively, approximately a $3.1 and $6.6 million decrease. As noted above, due to a production volume decline from the ceasing of operations at Project Marie and switching to a data hosting model from a proprietary mining model at Project Sophie, offset with increases at Project Dorothy 1B due to energization in the third quarter of 2023, the Company saw significant declines between periods.

Cost of data hosting revenue, exclusive of depreciation: Cost of data hosting was approximately $2.2 million for the three months ended September 30, 2023 compared to $1.1 million for the three months ended September 30, 2022. This increase was due to factors noted above in which was mainly due to Project Dorothy 1A contributing approximately $1.8 million of data hosting costs, in which did not occur for the 3 months ended September 30, 2022. The increase of $1.8 million was offset by approximately $700 thousand due to hosting contract arrangement for the three months ended September 30, 2022 in which electricity costs were not pass-through costs, compared to the hosting contracts for the three months ended September 30, 2023 in which the electricity costs were pass through costs. In addition, the new contract at Project Sophie began in mid April 2023 and energization for Project Dorothy 1A begin in May 2023. Cost of data hosting revenue was approximately $3.2 million for the nine months ended September 30, 2023 and $3.2 million for the nine months ended September 30, 2022. Although the fluctuation remained consistent, there was an increase in costs at Project Dorothy 1A of approximately $2.3 million, offset as a direct result of Project Marie’s operations ceasing in February 2023, in which the hosting contract was also terminated at the same time. While the Company began data hosting operations at Project Sophie in mid April 2023, the energy costs noted within the recent hosting agreements were pass-through costs and lowered the costs of data hosting creating a $2.3 million decrease for Project Sophie and Marie for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

Cost of revenue- depreciation: Depreciation costs associated with cryptocurrency and data hosting revenue was approximately $1.2 million and $2.4 million for the three and nine months ended September 30, 2023 compared to $6.0 million and $15.9 million for the three and nine months ended September 30, 2022. The significant decline between the comparative periods related to a higher net book value in property, plant, and equipment as of September 30, 2022 of approximately $63.5 million compared to $45.9 million as of September 30, 2023. In fiscal year 2022, the Company impaired approximately $47.4 million of property, plant and equipment of which $28.1 was in the third quarter of fiscal year 2022 and $18.6 million was in the fourth quarter of fiscal year 2022, in which in turn resulted in lower net book value of property, plant and equipment as of September 30, 2023 and a decline in depreciation costs for the period. For the three months ended September 30, 2023, the Company has begun to invest more in capital expenditures in which they have more than tripled purchases compared to the first six months of fiscal year 2023, as such the Company expects to see depreciation costs to significantly increase the next several months.

In addition, employee related expenses decreased approximately $94 thousand for the three months ended September 30, 2023 compared to the three months ended September 30, 2022 as employees performed more traveling for events and site visits in the prior year compared to current year. Wages and salaries, including fringe benefits decreased by approximately $340 thousand due to reduction in personnel costs and headcount reduction of approximately 8 employees between the comparable periods.

Consulting, professional, and legal fees decreased by approximately $1.4 million for the three months ended September 30, 2023 compared to three months ended September 30, 2022. The main decrease in legal fees related to legal fees associated with Dorothy development agreements for Spring Lane, PPA and ERCOT that were incurred for the three months ended September 30, 2022 for an amount of approximately $780 thousand, in which were not incurred for the three months ended September 30, 2023.

During the three and nine months ended September 30, 2022, the Company concluded that there were impairment indicators on property, plant and equipment associated with the S-9 and L3 miners in storage. As a result, a quantitative impairment analysis was required as of September 30, 2022. As such, the Company reassessed its estimates and forecasts as of September 30, 2022, to determine the fair values of the S-9 and L3 miners held in storage. As a result of the analysis, as of September 30, 2022, the Company concluded the carrying amount of the property, plant and equipment associated with the S-9 and L3 miners exceeded its fair value, which resulted in impairment charges of $1.1 million and $1.9 million for the three and nine months ended September 30, 2022. In addition, the Company assessed the active miners in operations and determined that based on Bitcoin pricing and other market factors, there has been a decline in the market value of the active miners in the Company’s operations. As a result, a quantitative impairment analysis was required as of September 30, 2022. It was determined based on the analysis, that the undiscounted cash flow with residual value was less than the net book value as of September 30, 2022, confirming the existence of a triggering event, and therefore required an impairment to be recognized. Based on the fair value of the active miners compared to the net book value, the Company determined that an impairment of approximately $26.9 million to be recognized for the three and nine months ended September 30, 2022 in relation to active miners in the prior year period.

Interest expense: Interest expense for the three months ended September 30, 2023, was $495 thousand which primarily related to mainly related to interest accrued on the Navitas loan of $85 thousand and interest on the NYDIG Financing Loan of approximately $405 thousand.

For Project Sophie, the Company incurred a loss on sale of approximately $29 thousand in which was due to the shift at the site data hosting services compared to proprietary mining beginning in the second quarter of fiscal 2023, the Company was looking to sell all the miners at the site. The miners sold at the Sophie site were sold for proceeds of approximately $891 thousand in which had a net book value of $921 thousand. For Project Marie, the Company sold the Tesseracks and remaining assets for proceeds of $320 thousand in which included a note receivable of $240 thousand. In addition, the Company incurred a $251 thousand loss on sale of assets in relation to NYDIG collateral finalization in which the Company had to pay for expenses and legal fees in related to the disposition.

There were additional proceeds of $36 thousand from sale on equipment in March 2023, in which resulted in a gain of approximately $3 thousand of scrap and other equipment. There was an additional gain of $48 thousand for the sale of the M30 miners with two customers, in which the Company sold the miners for a higher value than their current net book value for which they received proceeds of approximately $561 thousand in which the miners had a net book value of approximately $513 thousand. The Company incurred a $1.0 million and $2.6 million loss for the three and nine months ended September 30, 2022, respectively, in connection with the disposal and sale of miners and equipment with a net book value of approximately $3.3 million and $5.4 million for the three and nine months ended September 30, 2022, respectively, which the Company received net proceeds of $2.35 million and $2.8 million for the three and nine months ended September 30, 2022.

Other expense, net: For the three and nine months ended September 30, 2023, was approximately $74 thousand and $301 thousand, respectively. The main reason for the balance for the three months ended September 30, 2023 was due to a prepayment penalty of approximately $47 thousand in association with payoff of the notes payable that were entered in July 2023, as well as additional other expenses. For the nine months ended September 30, 2023, there was a $250 thousand expense in relation to an extension fee for the noteholders of the convertible debt when the 2nd Amendment was signed on May 11, 2023, in addition to the prepayment penalty for the notes payable in the third quarter of fiscal 2023. There were no material other expenses for the three and nine months ended September 30, 2022.

Income tax (expense) benefit: Income tax (expense) benefit for the three and nine months ended September 30, 2023 was an expense of $569 thousand and an income tax benefit of $524 thousand compared to an income tax benefit the three and nine months ended September 30, 2022 of $547 thousand and approximately $1.4 million. The balance for the three and nine months ended related to deferred tax amortization 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 (October 29, 2021), 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 nine months ended September 30, 2023 and 2022, the Company amortized $547 thousand and $1.6 million. For the three and nine months ended September 30, 2023, these amounts were offset with a timing difference due to significant increase for in-service capital assets for the three months ended September 30, 2023 which created an offset of approximately $1.1 million in deferred income tax expense. Income tax benefit from continuing operations for the three and nine months ended September 30, 2022 was $547 thousand and $1.3 million, respectively, which mainly related to the amortization of deferred tax liability for the strategic pipeline discussed above, offset by a $295 thousand deferred tax expense incurred in the second quarter of 2022 related to increasing the Company’s valuation allowance associated with the deferred tax asset.

Net Income from discontinued operations: The Company’s MTI Instruments business was reported as discontinued operations up to the date of the sale on April 11, 2022. Net income from discontinued operations for the three and nine months ended September 30, 2022 was $7.5 million and $7.8 million, respectively. This was primarily due to the $7.6 million gain on the sale reported in the second quarter of 2022 for MTI Instruments offset with sales and costs for the three and a half months of operations of MTI Instruments in fiscal year 2022. The Company sold MTI Instruments in fiscal year 2022 and did not incur any additional gains or costs for the three and nine months ended September 30, 2023.

Net (income) loss attributable to non-controlling interest: Net income attributable to non-controlling interest for the three months ended September 30, 2023 was $646 thousand.

As the Company was generating revenue from energization at Project Dorothy, the Company began to see a shift from a net loss to profit within non-controlling interest. The Company notes that Springlane didn’t obtain any interest in DVSL until the third quarter of 2022 and Navitas didn’t obtain any interest in DV until the second quarter of 2023. For the three months ended September 30, 2022, the amount relates to Springlane’s 32.2% noncontrolling interest of the Net Loss in Soluna DVSL for the 3 months ended September 30, 2022 of $272 thousand. Net loss attributable to non-controlling interest for the nine months ended September 30, 2023 was $206 thousand. The $206 thousand net loss was attributable to a net loss in relation to the Company’s DVSL entity for $6 thousand and $200 thousand net loss in relation to the Company’s DV entity. For the first six months of fiscal 2023, DVSL was generating a non-controlling interest net loss, but with the energization at Dorothy 1A in effect beginning in the second quarter of 2023, the DVSL entity began to generate net profits, while DV was generating a net loss for the first four months of operations, but with energization beginning in the third quarter of fiscal 2023, the DV entity began to generate a net profit in non-controlling interest. Net loss attributable to non-controlling interest for the nine months ended September 30, 2022 was $272 thousand in relation to the Company’s DVSL entity.

Non-GAAP Measures

In addition to financial measures calculated in accordance U.S. generally accepted accounting principles (“GAAP”), we also use “Adjusted EBITDA.” Adjusted EBITDA is a non-GAAP financial measure defined as net income (loss) from continuing operations before interest, taxes, depreciation and amortization (“EDITDA”) adjusted to eliminate the effects of certain non-cash, non-recurring items, which do not reflect our ongoing strategic business operations. Management believes that Adjusted EBITDA results in a performance measurement that represents a key indicator of the Company’s business operations of cryptocurrency mining and data hosting.

We believe Adjusted EBITDA can be an important financial measure because it allows management, investors, and our Board of Directors to evaluate and compare our operating results, including our return on capital and operating efficiencies, from period-to-period by making such adjustments. Non-GAAP financial measures are subject to material limitations as they are not in accordance with, or a substitute for, measurements prepared in accordance with GAAP. For example, we expect that stock-based compensation costs, which is excluded from the non-GAAP financial measures, will continue to be a significant recurring expense over the coming years and is an important part of the compensation provided to certain employees, officers, and directors. Similarly, we expect that depreciation and amortization of fixed assets will continue to be a recurring expense over the term of the useful life of the assets.

Adjusted EBITDA is provided in addition to, and should not be considered to be a substitute for, or superior to net income, the comparable measure calculated in accordance with U.S. GAAP. Further, Adjusted EBITDA should not be considered as an alternative to revenue growth, net income, diluted earnings per share or any other performance measure calculated in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. Adjusted EBITDA has limitations as an analytical tool, and you should not consider such measures either in isolation or as substitutes for analyzing our results as reported under GAAP.

Reconciliations of Adjusted EBITDA to net income from continuing operations, the most comparable GAAP financial metric, for historical periods are presented in the table below:

Liquidity and Capital Resources

Several key indicators of our liquidity are summarized in the following table:

(Dollars in thousands)	Nine Months Ended or As of			Nine Months Ended or As of			Year Ended or As of

The Company had a consolidated accumulated deficit of approximately $244.3 million as September 30, 2023. As of September 30, 2023, the Company had negative working capital of approximately $13.2 million, $12.2 million outstanding principal in notes payable that may be converted to common stock, a subsidiary of the Company that defaulted on equipment financing and has a current outstanding loan of $8.0 million, and a 2-year $2.05 million principal loan commitment to Navitas, The Company had outstanding commitments as of September 30, 2023, related to SCI for approximately $150 thousand in capital expenditures, and approximately $5.6 million of cash available to fund its operations.

Based on business developments, including changes in production levels, staffing requirements, and network infrastructure improvements, we will require additional capital equipment in the foreseeable future. With the Company’s shift in focus of the business, and the sale of the MTI Instruments business that occurred in April 2022, the Company has now exited the instrumentation business and is focused on developing and monetizing green, zero-carbon computing and cryptocurrency mining facilities, as well as facilities capable of hosting customers engaged in cryptocurrency mining.

We plan to continue funding operations from our current cash position and our projected 2023 cash flows pursuant to management’s plans. If necessary, we may also seek to supplement our resources by increasing credit facilities to fund operational working capital and capital expenditure requirements. We expect to fund growth, including additional development and build-outs of data centers through project-level capital raising and equity sale activities, to the extent that we can successfully raise capital through sales of additional debt or equity securities, as well as a variety of project specific funding options. Any additional financing, if required, may not be available to us on acceptable terms or not at all.

As shown in the accompanying financial statements, the Company did not generate sufficient revenue to generate net income, a negative working capital, and has a cash used in operations position as of September 30, 2023. 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 unaudited financial statements as of September 30, 2023, or November 14, 2023.

Further, various 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. If our revenue estimates are off either in timing or amount, or if cash generated from operations is insufficient to satisfy the operational working capital and capital expenditure requirements, the Company plans to implement additional steps to ensure liquidity including, but not limited to, the deferral of planned capital spending and/or delaying existing or pending product development initiatives; alternatively, the Company may be required to obtain credit facilities or other loans, if available, to fund these initiatives. However, the Company is actively monitoring this situation and the possible effects on our financial condition, liquidity, operations, suppliers, and the industry.

Operating Activities

Net cash used in operations for continuing operations was approximately $4.4 million during the nine months ended September 30, 2023.

Debt

On September 15, 2021, the Company entered into a $1.0 million unsecured line of credit with KeyBank National Association (“KeyBank”), that will, among other things, allow the Company to request loans and to use the proceeds of such loans for working capital and other general corporate purposes (the “KeyBank facility”). The line of credit bears interest at a rate of Prime + 0.75% per annum. Accrued interest is due monthly and principal is due in full following KeyBank’s demand. As of January 1, 2022, the entire line of credit of $1.0 million was drawn and outstanding. As of September 30, 2023, the entire original $1.0 million outstanding balance has been paid down, and the Company did not have an outstanding balance as of September 30, 2023. The Company does not plan to draw down on the line of credit in the foreseeable future. In addition, future drawdowns may require pre-approval by KeyBank.

On October 25, 2021, the Company issued to certain institutional investors secured convertible notes in the aggregate principal amount of approximately $16.3 million for an aggregate purchase price of $15.0 million. The notes are convertible, subject to certain conditions, at any time at the option of the investors, into an aggregate of 71,043 shares of the Company’s common stock. On July 19, 2022, the Company entered into the Addendum with the Noteholders to amend the terms the October Secured Notes. Pursuant to the Addendum, a portion of the October Secured Notes would be converted and may be redeemed in three tranches, with each tranche of $1,100,000 required to be converted into common stock in each case at the then in effect conversion price of the October Secured Notes, with such price, prior to each conversion, to be reduced (but not increased) to a 20% discount to the 5-day VWAP of the Company’s common stock. In addition, the Noteholders may require the Company to redeem up to $2,200,000 worth of October Secured Notes in connection with each tranche at a rate of $1.20 for every $1.00 owed, less the amount of October Secured Notes converted during such tranche, not including the required conversion amount if the Noteholders are unable to convert out of such amount of the October Secured Notes in each tranche. The Company is also required to deposit up to $1,950,000 in an escrow account in connection with each tranche to satisfy any redemptions, except with respect to the first tranche as provided in the Addendum Amendment. The Addendum also provides the right for the Company to pause the commencement of the conversion of the second and third tranches each for 45 days in the event the Company pursues an equity financing. Since inception, the Company has converted down approximately $3.8 million on the convertible debt. On September 13, 2022, the Company entered into the Addendum Amendment with the Noteholders to amend the terms to extend the maturity date to April 25, 2023, and increase the principal amount of the October Secured Notes by approximately $520 thousand for a total outstanding principal amount of approximately $13 million. The events of default stated in the Notice of Acceleration and Repossession defined below with NYDIG constituted a cross-default under the terms of secured convertible notes issued to the Noteholders. In addition to such cross-default, the failure of the Company pursuant to the Addendum dated as of July 19, 2022, to escrow an aggregate amount of $950,000 for the benefit of the Noteholders by December 21, 2022, constitutes an event of default under the Notes. Due to the defaults noted, the Company did not enter into the second and third tranche of conversions. As such, beginning on November 30, 2022, the Company had been accruing interest of 18% per annum on the outstanding principal amount due to the default. On March 10, 2023, the Company entered into a Second Addendum Amendment with the Noteholders, in which the Company paid approximately $617 thousand through the Company’s restricted escrow accounts and contemporaneously with the payment, the Noteholders waived all existing events of default arising under the convertible notes. On May 11, 2023, the Company entered into the Second Amendment with the Noteholders in which increased the principal outstanding balance to approximately $13.3 million and extending the maturity date to July 2024. The Noteholders have converted approximately $1.05 million between May 11^th to September 30, 2023, reducing the principal balance to approximately $12.2 million as of September 30, 2023.

On January 14, 2022, the Company effected an initial drawdown under the Master Equipment Finance Agreement with NYDIG in the aggregate principal amount of approximately $4.6 million that bore interest at 14%. On January 26, 2022, the Company had a subsequent drawdown of $9.6 million. On December 20, 2022, Soluna MC Borrowing 2021-1 LLC (“Borrower”) received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG with respect to the Master Agreement, by and between Borrower and NYDIG. The obligations of Borrower under the Master Agreement 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. As such, the principal balance of $10.5 million as of December 31, 2022 became due immediately and the Borrower shall bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing. As of September 30, 2023, the Company has an outstanding loan balance of approximately $8.0 million and an outstanding accrued interest and penalties of approximately $810 thousand.

51

On May 9, 2023, Soluna DV ComputeCo, LLC and Navitas West Texas Investments SPV, LLC entered into a 2-year Loan Agreement for $2,050,000. The unpaid principal balance of the Term Loan shall bear interest at per annum rate equal to 15%. As of September 30, 2023, the Company has accrued approximately $122 thousand in interest expense, and the entire principal balance remains outstanding.

Critical Accounting Policies and Significant Judgments and Estimates

The above discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Note 2, Accounting Policies, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022 includes a summary of our most significant accounting policies. There have been no material changes to the critical accounting policies previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022. The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, income taxes, fair value measurements, and stock-based compensation. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Periodically, our management reviews our critical accounting estimates with the Audit Committee of our Board of Directors.

Factors Expected to Affect Our Future Results

We expect our revenues to comprise a combination of: (i) block rewards in Bitcoin, which are fixed rewards programmed into the Bitcoin software that are awarded to a miner or a group of miners for solving the cryptographic problem required to create a new block on a given blockchain and (ii) transaction fees in Bitcoin, which are flexible fees earned for verifying transactions in support of the blockchain and (iii) hosting revenues whereby the Company provides electrical power and network connectivity to cryptocurrency mining customers, and the customers pay a stated amount and rate.

Our revenues are directly impacted by changes in the market value of Bitcoin. For example, the average Bitcoin price for 2020 and 2021 was $11,057 and $47,385, respectively. Bitcoin price generally declined throughout 2022. As of December 31, 2022, the price of Bitcoin was $16,526. We noted that the price of Bitcoin has increased for a nine month period from $16,526 to $26,967 as of September 30, 2023, however declined for a three month period of $30,477 from June 30, 2023 to $26,967 as of September 30, 2023. Furthermore, block rewards are fixed, and the Bitcoin network is designed to periodically reduce them through halving. Currently the block rewards are fixed at 6.25 Bitcoin per block, and it is estimated that it will halve again to 3.125 Bitcoin in April 2024. The halving events happen without any regard to ongoing demand, meaning that if the ongoing demand remains the same after a halving event, whatever demand was being met by new supply will be restricted, which may necessitate an adjustment of the price of Bitcoin, though there is no definitive evidence of a causal link between Bitcoin’s programmatic decrease in supply and broadening demand. Once the halving occurs, we expect that it could have a negative impact on our revenues as the reward for each Bitcoin mines will be reduced.

Bitcoin miners also collect transaction fees for each transaction they confirm. Miners validate unconfirmed transactions by adding the previously unconfirmed transactions to new blocks in the blockchain. Miners are not forced to confirm any specific transaction, but they are economically incentivized to confirm valid transactions as a means of collecting fees. Miners have historically accepted relatively low transaction confirmation fees, because miners have a very low marginal cost of validating unconfirmed transactions; however, unlike the fixed block rewards, transaction fees may vary, depending on the consensus set within the network.

As the use of the Bitcoin network expands and the total number of Bitcoin available to mine and, thus, the block rewards, declines over time, we expect the mining incentive structure to transition to a higher reliance on transaction confirmation fees, and the transaction fees to become a larger proportion of the revenues to miners. These changes could have an indirect effect on our revenues from hosted customers engaging in cryptocurrency mining.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable.

Item 4. Controls and Procedures

The certifications of our Chief Executive Officer and Chief Financial Officers are attached as Exhibits 31.1 and 31.2 to this Quarterly Report on Form 10-Q include, in paragraph 4 of such certification, information concerning our disclosure controls and procedures and internal control over financial reporting. Such certification should be read in conjunction with the information contained in this Item 4 for a more complete understanding of the matters covered by such certification.

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of SHI’s disclosure controls and procedures as of September 30, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the U.S. Securities and Exchange Commission’s (the “SEC”) rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. We recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and we necessarily apply our judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2023, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

(b) Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended September 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

At any point in time, we may be involved in various lawsuits or other legal proceedings. Such lawsuits could arise from the sale of products or services or from other matters relating to our regular business activities, compliance with various governmental regulations and requirements, or other transactions or circumstances.

We have been named as a party in the December 19, 2019 United States Environmental Protection Agency (“EPA”) Demand Letter regarding the Malta Rocket Fuel Area Superfund Site (“Site”) located in Malta and Stillwater, New York, in connection with an alleged release of hazardous materials into the environment. The EPA is seeking reimbursement of response costs from all named parties in the amount of approximately $358 thousand plus interest in connection with the investigation and disposal activities associated with the various drum caches discovered at the Site, issuance of the Explanation of Significant Differences (“ESD”) of the Site, and implementation of the work contemplated by the ESD. We consider the likelihood of a material adverse outcome with respect to this matter to be remote and do not currently anticipate that any expense or liability that we may incur as a result of this matter in the future will be material to the Company’s business or financial condition.

NYDIG filed a complaint against Soluna MC Borrowing 2021-1 LLC (“Borrower”) and Soluna MC LLC (“Guarantor”, and together with Borrower, “NYDIG Defendants”) in Marshall Circuit Court of the Commonwealth of Kentucky on December 29, 2022 regarding a series of loans made by NYDIG to Borrower pursuant to a master equipment finance agreement that were secured by certain assets of Borrower and guaranteed by Guarantor pursuant to a written guaranty agreement executed by Guarantor. The Court issued on February 15, 2023, an agreed order granting NYDIG’s motion for writ of possession which, among other things, ordered parties to provide NYDIG access to the collateral described therein and preserved the rights of NYDIG to pursue a deficiency judgment against the NYDIG Defendants. Also on February 15, 2023, the NYDIG Defendants filed their answer and affirmative defenses in this proceeding. The NYDIG Defendants believe that NYDIG has liquidated some of the collateral securing the loans and anticipate that NYDIG will complete the liquidation of collateral and continue to prosecute the complaint to obtain a judgment against the NYDIG Defendants. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023, seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The NYDIG Defendants noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the NYDIG Defendants are currently disputing.

In September 2023, Atlas Technology Group LLC (“Atlas”) filed a complaint against Soluna MC LLC (formerly EcoChain Block LLC) (“Soluna MC”), Soluna Computing, Inc., and Soluna Holdings, Inc. (collectively, the “Atlas Defendants”) in the Supreme Court of the State of New York, County of New York regarding a co-location services agreement between Soluna MC and Atlas.  Atlas alleges that the termination of such agreement by Soluna MC was a breach and asserts various claims, including breach of contract and the return of pre-paid fees. The claim requests a judgement against the Atlas Defendants for the return of pre-paid fees of approximately $464 thousand and additional damages to be determined at trial of not less than $7.9 million, and reimbursement of costs including legal fees and other costs. The complaint also contains references to alter ego liability and piercing the corporate veil.  The Atlas Defendants believes they have substantial factual and legal defenses to these claims and intend to defend the claims vigorously.

The referenced pre-paid fees of approximately $464 thousand have been reported in previous filings on Soluna MC’s balance sheet. No reserves have been established for any other claims asserted in such complaint.

Item 1A. Risk Factors

Part II, Item 1A (Risk Factors) of our most recently filed Annual Report on Form 10-K with the SEC, filed on March 31, 2023, sets forth information relating to important risks and uncertainties that could materially adversely affect our business, financial condition and operating results. Except as to the risk factors set forth below and to the extent that information disclosed elsewhere in this Quarterly Report on Form 10-Q relates to such risk factors (including, without limitation, the matters described in Part I, Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations – Statement Concerning Forward Looking Statements), there have been no material changes to our risk factors disclosed in our most recently filed Annual Report on Form 10-K. Those risk factors continue to be relevant to an understanding of our business, financial condition and operating results, however, and, accordingly, you should review and consider such risk factors in making any investment decision with respect to our securities.

Our failure to meet the continued listing requirements of the Nasdaq could result in a delisting of our securities.

On October 13, 2023, we effected a 1-for-25 Reverse Stock Split of the Common Stock, in order to increase the per share market price of the Common Stock to meet the minimum per share price requirement for continued listing on Nasdaq, and on October 30, 2023, we received a notice of compliance from NASDAQ. However, there can be no assurance that we will be able to continue to comply with NASDAQ’s minimum per share price requirement or other continued listing standards in the future. If we fail to satisfy the continued listing requirements of NASDAQ, NASDAQ may take steps to delist our securities. In the event the Common Stock is delisted from NASDAQ, such a delisting would likely have a negative effect on the price of our securities, including the Common Stock, and would impair your ability to sell or purchase our securities when you wish to do so. In addition, in the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow any of our securities to become listed again, stabilize the market price or improve the liquidity of our securities or prevent future non-compliance with NASDAQ’s listing requirements.

Additionally, if our securities are not listed on, or become delisted from, NASDAQ for any reason, and are quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of our securities may be more limited than if it were quoted or listed on NASDAQ or another national securities exchange. You may be unable to sell your securities unless a market can be established or sustained.

If an active, liquid public trading market for the Common Stock does not develop or is not maintained, we may be limited in our ability to raise capital by selling shares of Common Stock and our ability to acquire other companies or assets by using shares of Common Stock or other SHI securities as consideration.

The ultimate effect of the Reverse Stock Split on the market price of our Common Stock cannot be predicted with any certainty and may decrease the liquidity of our Common Stock and magnify any decrease in our overall market capitalization.

The ultimate effect of the Reverse Stock Split on the market price of our Common Stock cannot be predicted with any certainty, and we cannot assure you that the Reverse Stock Split will result in any or all of the expected benefits for any meaningful period of time, or at all. While we expect that the reduction in the number of outstanding shares of Common Stock will proportionally increase the market price of our Common Stock, we cannot assure you that the Reverse Stock Split will increase the market price of our Common Stock by a multiple of the Reverse Stock Split ratio or result in any permanent or sustained increase in the market price of our Common Stock. The market price of our Common Stock depends on multiple factors, many of which are unrelated to the number of shares outstanding, including our business and financial performance, general market conditions and prospects for future success, any of which could have a counteracting effect to the Reverse Stock Split on the per share price.

In addition, the Reverse Stock Split also reduced the total number of outstanding shares of Common Stock, which may lead to reduced trading and a smaller number of market makers for our Common Stock. As a result of a lower number of shares outstanding, the market for our Common Stock may also become more volatile.

Finally, the decline in the per share price of our Common Stock and the decline in our overall market capitalization may be greater following the Reverse Stock Split than would have occurred in the absence of a Reverse Stock Split. Any reduction in our market capitalization may be magnified as a result of the smaller number of total shares of Common Stock outstanding following the Reverse Stock Split.

Risk of price of Bitcoin and other cryptocurrency markets could have a negative impact for Data Hosting customer with a Profit-Sharing agreement.

The Company has a contract with a customer included within Data Hosting revenue.  The contract states a Profit-Sharing aspect in which the Company will share in any net profits earned, or in the event that the customer experiences negative net profits (i.e., a loss), the customer shall split the loss derived from the operations in connection with the venture outlined in contract in the ratio of fifty percent (50%) to the Company and fifty percent (50%) to the customer.  The Company bears the risk that if the mined revenue doesn’t exceed the costs, the Company could bear net losses for hosting with the customer.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On October 10, 2023, the Company effectively issued 39,600 shares of common stock to HEL at a price basis of $5.00 per share in relation to conditions being met within the Merger Agreement in relation to energization and retention of employees. The shares were issued in reliance upon an exemption pursuant to Section 4(a)(2) of the Securities Act.

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.

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.”

SHI currently conducts its business through its wholly-owned subsidiary, Soluna Computing, Inc. (“SCI”). SCI is engaged in mining of cryptocurrency through data centers that can be powered by renewable energy sources. Recently, SCI has built modular data centers that are used for cryptocurrency mining though proprietary mining and hosting business models. SCI intends to continue to develop and build, modular data centers that use wasted renewable energy for cryptocurrency mining and in the future can be used for intensive, high performance computing applications, such as artificial intelligence and machine learning, with the goal of providing a cost-effective alternative to battery storage or transmission lines.

SCI was incorporated in Delaware on January 8, 2020 as EcoChain, Inc., which operates cryptocurrency mining facilities that perform proprietary mining and data hosting services that integrate with the cryptocurrency blockchain network. 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”). We earn revenue from this business as the mined cryptocurrencies are converted into U.S. dollars. 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 shut down. On April 6 and June 28, 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 September 30, 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 megawatts 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 September 30, 2023, has a 15% ownership interest in Soluna DVSL ComputeCo, LLC (“DVSL”), and 51% ownership interest in Soluna DV ComputeCo, LLC (“DV”) in which are included within the Project Dorothy site, as discussed further in Note 16.

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% of the issued and outstanding common stock of MTI Instruments. As a result of the foregoing, the MTI Instruments business was reported as discontinued operations in our consolidated financial statements as of December 31, 2022, and prior periods included in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 31, 2023 (the “Annual Report”). 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.

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 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 $7.8 million.

Going Concern and Liquidity

The Company’s condensed unaudited financial statements as of September 30, 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 condensed unaudited financial statements, the Company did not generate sufficient revenue to generate net income and has a cash used in operations position during the nine months ending as of September 30, 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 condensed unaudited financial statements as of September 30, 2023, or November 14, 2023.

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 million. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Soluna MC, LLC (“Guarantor”), under a piercing of the corporate veil claim relating to the Guarantor together with Borrower, (“NYDIG Defendants”) debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023, seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

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 million in project financing subject to various milestones and conditions precedent and in August 2022, the Company entered into an agreement with Spring Lane for an initial funding of up to $12.5 million from the previously agreed-upon $35.0 million commitment from Spring Lane for Project Dorothy for a 32% ownership as of year-end. As of December 31, 2022, the Company had received approximately $4.8 million worth of contributions from Spring Lane. In February and concluding on March 10, 2023, the Company entered into a series of Purchase and Sale Agreements with Spring Lane for a total purchase price of $7.5 million for the sale of Series B membership interests owned by SHI. The capital was funded and used to help complete the substation interconnection and the final stages of Project Dorothy, Soluna’s flagship project in West Texas, and corporate operations and general expenses of Soluna. In this series of transactions, Spring Lane increased its stake in Soluna DVSL ComputeCo from approximately 32% to 85% and reduced SHI’s ownership from 68% to 15%.

In addition, on May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DV”) through Soluna DV Devco, LLC completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC, (“Navitas”) organized by Navitas Global, to complete the second phase of the Dorothy Project (“Dorothy 1B”). Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which the Company had contributed capital expenditures for the data center. Navitas has approximately $12.1 million cash contribution for the primary purpose of purchasing proprietary cryptocurrency miners and equipment necessary to put the Dorothy 1B Project into service. As a result of the contribution, the Company owns 51% of DV and Navitas owns 49% of DV.

On August 1, 2023, the Company had the second subsequent closing under the Securities Purchase Agreement dated December 5, 2022 among the Company and certain institutional investors. Pursuant to the SPA, the investors purchased approximately $774,000 in common stock and associated common stock purchase warrants, with a purchase price of $7.50 per share. Accordingly, at the second subsequent closing the Company issued to the investors 103,183 shares of Common Stock, together with associated warrants to purchase 206,367 shares of Common Stock.

For the first nine months ended September 30, 2023, the Company has sold under-utilized miners and equipment, and continues to evaluate opportunities to sell more miners and equipment for fiscal year 2023. In addition to the proceeds from the foregoing transactions and together with the Company’s available cash on hand for available use of approximately $5.6 million as of September 30, 2023, the Company will need additional capital raising activities, to meet its outstanding commitments relating to capital expenditures as of September 30, 2023 of approximately $150 thousand and other operational needs, as well as additional needs during 2023 and management continues 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.

Basis of Presentation

2. Basis of Presentation

In the opinion of management, the Company’s condensed unaudited 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, 2022 (“the Annual Report”).

The information presented in the accompanying condensed consolidated balance sheet as of December 31, 2022 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, 2023 and September 30, 2022.

Principles of Consolidation

The condensed unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, SCI. 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 (the “Reverse Split”). The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023. The reverse stock split was approved by the Board of Directors and by shareholders at the annual meeting of the stockholders on June 29, 2023. At the effective time, 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 Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole 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 for continued listing on the Nasdaq. On October 30, 2023, the Company received a notice of compliance from NASDAQ.

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 per share (the “Series B Preferred Stock”), may be converted to Common Stock. The total number of shares of Series B Preferred Stock of the Company authorized for issuance remained at 187,500.

The effects of the Reverse Stock Split have been reflected in these condensed unaudited consolidated 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 and Restricted Cash

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months. As of September 30, 2023 and December 31, 2022, the Company had approximately $5.6 million and $1.1 million within cash and cash equivalents. In addition, for cash flow purposes, the Company had approximately $1.1 million as of September 30, 2022 within cash and cash equivalents.

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, 2023, the Company had restricted cash of approximately $4.4 million, in which $3.4 million was classified as current and $1.0 million was classified as non-current. On December 31, 2022, the Company had restricted cash of approximately $685 thousand, in which the entire balance was classified as current. The Company notes that there was no restricted cash balance as of September 30, 2022 for cash flow purposes. The balance in restricted cash relates to funds held in escrow accounts due to sales of equipment that were executed, in which the Company can release to the convertible noteholders only if they request their share of funds. If no funds are distributed to the convertible noteholders from the escrow account by December 31, 2023, the funds may be used for general purposes for the Company. In addition, there was a restricted deposit held with a customer that was for less than 12 months. The Company has a long term restricted cash balance in relation to a collateralized deposit.

Deposits and credits on equipment

As of September 30, 2023 and December 31, 2022, the Company had approximately $975 thousand and $1.2 million in deposits and credits on equipment, that had not yet been received by the Company as of the year end. Once the Company receives such equipment in the subsequent period, the Company will reclassify such balance into Property, Plant, and Equipment. The credit on equipment is restricted to be used on future purchases by March 1, 2024 (“expiration date”). The Company notes that if an order is not executed by the expiration date, the credit would be forfeited. The Company intends to utilize the full credit balance for future orders prior to the expiration date.

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.

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 million in which were written off the Company’s books in the first quarter of 2023, offsetting the outstanding accrued interest and penalty first, then the remaining outstanding loan. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling approximately $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing.

In January 2023, the Company sold M20 and M21 miners for a loss on sale of equipment of approximately $82 thousand in which we received proceeds of $213 thousand for our M20 and M21 miners which were previously reported as held for sale as of December 31, 2022, in which had a net book value of $295 thousand. There were additional proceeds of $36 thousand in March 2023, in which resulted in a gain of approximately $3 thousand of scrap and other equipment. This was offset with a gain on sale of approximately $48 thousand in relation to the sale of M30 miners in May and June of 2023, which the Company sold the miners for a higher value than the current net book value. The Company received proceeds of approximately $561 thousand in which the miners had a net book value of approximately $513 thousand. In addition, the Company sold Switchgear and M31 miners for cash proceeds of approximately $476 thousand in which no gain or loss was recognized as the switchgear and miners were sold at net book value. For the three months ended September 30, 2023, the Company incurred a loss on sale of fixed assets of approximately $373 thousand in relation to the sale of miners for Project Sophie and sale of the remaining Project Marie fixed assets including the Tesseracks (mobile, Bitcoin Mining Equipment). For Project Sophie, the Company incurred a loss on sale of approximately $30 thousand in which was due to the shift at the project site to data hosting services compared to proprietary mining beginning in the second quarter of fiscal 2023, the Company was looking to sell all the miners at the site as noted below within “Equipment held for sale”. The miners sold at the Sophie site were sold for proceeds of approximately $891 thousand in which had a net book value of approximately $921 thousand. For Project Marie, the Company sold the Tesseracks and remaining assets for a loss of approximately $92 thousand for the three months ended September 30, 2023 in which the Company received proceeds of $320 thousand in which included a note receivable of $240 thousand that is outstanding as of September 30, 2023. In addition, the Company incurred approximately a $251 thousand loss on sale of assets in relation to NYDIG collateral finalization in which the Company had to pay for expenses and legal fees in related to the disposition. The Company incurred a $1.0 million and $2.6 million loss for the three and nine months ended September 30, 2022 in connection with the disposal of miners and equipment with a net book value of approximately $3.3 million and $5.4 million for the three and nine months ended September 30, 2022 in which the Company received proceeds of $2.35 million and $2.8 million for the three and nine months ended September 30, 2022.

During the nine months ended September 30, 2023, the Company had impairment charges of approximately $418 thousand in which related to impairment of approximately $165 thousand for power supply units (PSUs) at the Sophie location, $84 thousand for M31 miners based on sales of other recent M31 miners, in which the Company wrote down the net book value to sale price of the sold M32 miners, and $169 thousand due to revaluing the S19 miners to the current market conditions. During the three and nine months ended September 30, 2022, the Company concluded that there were impairment indicators on property, plant and equipment associated with the S-9 and L3 miners in storage. As a result, a quantitative impairment analysis was required as of September 30, 2022. As such, the Company reassessed its estimates and forecasts as of September 30, 2022, to determine the fair values of the S-9 and L3 miners held in storage. As a result of the analysis, as of September 30, 2022, the Company concluded the carrying amount of the property, plant and equipment associated with the S-9 and L3 miners exceeded its fair value, which resulted in impairment charges of $1.2 million and $2.0 million on the condensed unaudited consolidated statements of operations for the three and nine months ended September 30, 2022. In addition, the Company assessed the active miners in operations and determined there has been a decline in the market value of the active miners in the Company’s operations. As a result, a quantitative impairment analysis was required as of September 30, 2022. As such, the Company reassessed its estimates and forecasts as of September 30, 2022, to determine the undiscounted cash flows to determine whether the miners would be recoverable. It was determined based on the analysis, that the undiscounted cash flow with residual value was less than the net book value as of September 30, 2022, confirming the existence of a triggering event, and therefore required an impairment to be recognized. Based on the fair value of the active miners compared to the net book value, the Company determined that an impairment of approximately $26.8 million to be recognized for the three and nine months ended September 30, 2022.

Equipment held for sale

In April 2023, Project Sophie entered into a 25 MW hosting contract with a sustainability-focused Bitcoin miner, in which has shifted the Company’s business model at the Company’s modular data center at Project Sophie from proprietary mining to hosting Bitcoin miners for the customer. The Company is currently selling existing Bitcoin miners at the site and redeploying capital. The Company obtained Board of Director approval to sell all remaining miners at the Sophie location and as of September 30, 2023, approximately $248 thousand to be sold which the Company expects to sell within a year.

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 shares (the “Merger Shares”) of the Company’s common stock payable upon the achievement of certain milestones within five years after the effective date in the merger, as set forth in the merger agreement and the schedules thereto (the “Merger Consideration”). See Note 11 for further information regarding our relationship with HEL.

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 $725,000 and SHI issued to HEL 6,000 shares of SHI 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 (118,800) issuable as Merger Consideration, which issuance is contingent on the achievement of certain milestones of generating active Megawatts from Qualified Projects in which the Cost Requirement is satisfied 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 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% of the outstanding equity securities of SCI and/or the surviving corporation, or (C) a merger, consolidation, or other transaction in which the holders of SHI’s, SCI’s, or the surviving corporation’s outstanding voting securities immediately prior to such transaction own, immediately after such transaction, securities representing less than 50% of the voting power of the corporation or other entity surviving such transaction (excluding any such transaction principally for bona fide equity financing purposes, so long as, in the case of SHI or SCI (but not the surviving corporation) such transactions, individually and in the aggregate, do not result in a change in membership of such entity’s board of directors so that the persons who were members of the board of directors immediately prior to the first such transaction constitute less than 50% of the board membership at any time after such transaction(s) are consummated). Notwithstanding the foregoing, a transaction shall not constitute a Change of Control if its sole purpose is to change the state of SHI’s or SCI’s incorporation or to create a holding company that will be owned in the same proportions by the persons who held SHI’s or SCI’s securities immediately prior to such transaction; and
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 has 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 and 39,600 Merger Shares were issued on May 26, 2023 and October 10, 2023. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 59,400 Merger Shares, a total of 59,400 Merger Shares remain available for possible issuance pursuant to the terms of the Merger Agreement.

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 nine months ended September 30, 2023, the Company’s effective income tax rate was -4.52% and 1.57%, and for the three and nine months ended September 30, 2022, the Company’s effective tax rate on the tax benefit was -0.96% and -1.66%. The projected annual effective tax rate is less than the Federal statutory rate of 21%, primarily due to the change in the valuation allowance, as well as changes to estimated taxable income for 2023 and permanent differences. There was $569 thousand income tax expense and $547 thousand deferred income tax benefit for the three months ended September 30, 2023 and 2022. There was $524 thousand and $1.3 million deferred income tax benefit for the nine months ended September 30, 2023 and 2022.

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 nine months ended September 30, 2023 and 2022, the Company amortized $547 thousand and $1.6 million.

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 $35.6 million and $30.7 million on September 30, 2023 and December 31, 2022, respectively. We will continue to evaluate the ability to realize our deferred tax assets and related valuation allowance on a quarterly basis.

* Default interest was waived on March 10, 2023

On October 25, 2021, pursuant to a Securities Purchase Agreement (the “October SPA”), the Company issued to certain accredited investors (the “Noteholders”) (i) secured convertible notes in an aggregate principal amount of $16.3 million for an aggregate purchase price of $15 million (collectively, the “October Secured Notes”), which were, subject to certain conditions, convertible at any time by the investors, into an aggregate of 71,043 shares of the Company’s common stock, at a price per share of $229.50 and (ii) Class A, Class B and Class C common stock purchase warrants (collectively, the “October Warrants”) to purchase up to an aggregate of 71,043 shares of common stock, at an initial exercise price of $312.50, $375 and $450 per share, respectively. The October Warrants are legally detachable and can be separately exercised immediately for five years upon issuance, subject to applicable Nasdaq rules.

The October Secured Notes, subject to an original issue discount of 8%, had a maturity date (the “Maturity Date”) of October 25, 2022, which was extended to April 25, 2023 pursuant to the Addendum Amendment (as defined below), upon which date the October Secured Notes shall be payable in full. Commencing on the Maturity Date and also five (5) days after the occurrence of any Event of Default (as defined in the October Secured Notes), interest on the October Secured Notes will accrue at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. If any Event of Default or a Fundamental Transaction (as defined in the October Secured Notes) or a Change of Control (as defined in the October Secured Notes) occurs, the outstanding principal amount of the October Secured Notes, liquidated damages and other amounts owing in respect thereof through the date of acceleration, will become, at the Noteholder’s election, immediately due and payable in cash at the Mandatory Default Amount (as defined in the October Secured Notes). The October Secured Notes may not be prepaid, redeemed or mandatorily converted without the consent of the Noteholders. The obligations of the Company pursuant to the October Secured Notes are (i) secured to the extent and as provided in the Security Agreement, dated as of October 25, 2021, by and among the Company, MTI Instruments and SCI, Soluna MC, LLC and Soluna SW, LLC (both of which are wholly owned subsidiaries of SCI, and together with MTI Instruments and SCI, the “Subsidiary Guarantors”), and Collateral Services LLC (the “Collateral Agent”), as collateral agent for the Noteholders; and (ii) guaranteed, jointly and severally, by the Subsidiary Guarantors pursuant to each Subsidiary Guaranty, dated as of October 25, 2021, by and among each Subsidiary Guarantor and the Noteholders signatory to the October SPA, subject to subsequent modifications pursuant to the Addendum, the Addendum Amendment and the NYDIG Transactions.

On April 24, 2023, the Company reached agreement with the holders of the outstanding Convertible Notes to extend the maturity thereof until May 25, 2023. On May 11, 2023, the Company entered into a Second Amendment Agreement (the “Second Amendment”) as discussed further below with the holders of its October Secured Notes to extend the maturity date of the October Secured Notes to July 25, 2024.

On July 19, 2022, the Company entered into an addendum to the October SPA (the “Addendum”), pursuant to which a portion of the October Secured Notes would be converted and may be redeemed in three tranches, with each tranche of $1,100,000 required to be converted into common stock in each case at the then in effect conversion price of the October Secured Notes, with such price, prior to each conversion, to be reduced (but not increased) to a 20% discount to the 5-day volume weighted average price (“VWAP”) of the Company’s common stock. In addition, the Noteholders may require the Company to redeem up to $2,200,000 worth of October Secured Notes in connection with each tranche at a rate of $1.20 for every $1.00 owed, less the amount of October Secured Notes converted during such tranche, not including the required conversion amount if the Noteholders are unable to convert out of such amount of the October Secured Notes in each tranche. The Company is also required to deposit up to $1,950,000 in an escrow account in connection with each tranche to satisfy any redemptions, except with respect to the first tranche as provided in the Addendum Amendment (as defined below). The Addendum also provides the right for the Company to pause the commencement of the conversion of the second and third tranches each for 45 days in the event the Company pursues an equity financing. Pursuant to the Addendum, the exercise price of the Class A Warrants and Class B Warrants and certain other warrants to purchase up to 3,400 shares of common stock issued to the Noteholders on January 13, 2022, was reduced from $331.50 to $237.50 per share. In addition, the Company agreed to exchange the Class C Warrants for 11,841 shares of common stock, which exchanges were completed between July 25, 2022 and August 1, 2022.

On September 13, 2022, the Company and the Noteholders entered into an agreement further amending the Addendum (the “Addendum Amendment”), which among other matters, extended the Maturity Date of the October Secured Notes by six months to April 25, 2023, and increased the principal amount of the October Secured Notes by an aggregate of $520,241 for a total outstanding principal amount of $13,006,022. Also pursuant to the Addendum Amendment, $1.0 million previously deposited by the Company and held in escrow pursuant to the Addendum, was released back to the Company upon signing of the Addendum Amendment; however, on or before October 17, 2022, the Company (i) must deposit $1,000,000 into escrow as the Third Deposit, (ii) will not be required to make the second deposit of $1,950,000 pursuant to the Addendum and the Addendum Agreement, or redeem the first tranche of October Secured Notes. 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. In addition, pursuant to the Addendum Agreement, the Company issued to the Noteholders (i) 17,223 shares of the common stock (“New Shares”) in exchange for the Class B warrants, (ii) Class D common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $87.50 per share, (iii) Class E common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $112.50 per share, (iv) Class F common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $137.50 per share, and (v) Class G common stock purchase warrants to purchase up to an aggregate of 40,000 shares of common stock at an exercise price of $187.50 per share (together, the “New Warrants”). The New Warrants are exercisable immediately and have exercise period of 5 years from the issuance date.

Pursuant to the Addendum, between July 21, 2022 to August 3, 2022, the October Secured Notes with an aggregate principal amount of $1,100,000 converted into 11,734 shares of common stock, at the conversion price of $93.75. Pursuant to the Addendum and Addendum Amendment, the Company evaluated whether the new addendums qualified as debt modification or debt extinguishment, and based on ASC 470, Debt, the Company determined the Addendum and Addendum Amendment to fall under Debt Extinguishment and the Company would be required to fair value the new debt, and in turn write off the existing debt on the books. Based on the Company’s assessment, an extinguishment of debt of approximately $12.8 million was recorded in July and September of 2022 based on the Addendum and Addendum Amendment, the October Secured Notes had an aggregate principal amount of approximately $13.0 million and a fair value of approximately $14.1 million outstanding after the debt extinguishment. The fair value of the New Warrants issued to the Noteholders on September 13, 2022 was approximately $8.6 million and recorded as part of the loss on extinguishment of debt. The residual fair value of the New Warrants issued to non-lenders was $892 thousand and was recorded as equity with the offset as debt discount against the residual proceeds, in which the entire $892 thousand has been amortized, in which $0 and $474 thousand related to the three and nine months ended September 30, 2023. All the original debt issuance costs were written off with the extinguishment of the debt, and with the Addendum Amendment. As of the year ended December 31, 2022, the Company had to fair value the outstanding debt, in which it was determined to be approximately $12.3 million of a principal outstanding balance of approximately $13.0 million, in which the change in valuation compared to September 2022 when the Company had an extinguishment recorded, was recorded as a revaluation gain for the year ended December 31, 2022.

In connection with the Second Amendment, the Company paid an extension fee of $250,000 and increased the principal amount of the outstanding October Secured Notes by 14%. The Company also issued 240,000 new Class A warrants exercisable at $12.50 and 80,000 new Class B warrants exercisable at $20.00.

Subject to the Equity Conditions (as defined below), upon each trigger set forth below, the Company is allowed, once per trigger, require the Note holders to convert up to 20% percent of the outstanding amount of the October Secured Notes as:

(i)	the Company’s Common Stock trades for 10 consecutive days at or above $12.50 per share and at least 40,000 shares trade on each day.
(ii)	the Company’s Common Stock trades for 10 consecutive days at or above $17.50 per share and at least 40,000 shares trade on each day.
(iii)	the Company’s Common Stock trades for 10 consecutive days at or above $22.50 per share and at least 40,000 shares trade on each day.

The Equity Condition is met if all of the following conditions have been met: (i) the shares of Common Stock issuable upon the conversion are either registered under the Securities Act of 1933 or resellable under Rule 144 thereunder without any volume restrictions, (ii) the number of shares issuable to each Note holder are below 4.99% of the outstanding shares, (iii) at least 20 trading days has elapsed since the previous mandatory conversion, (iv) the Company is current in all the SEC filings, and (v) the Company has obtained all required approvals from NASDAQ, or any successor trading market, to list the Common Stock to be issued upon such conversion.

With the Second Amendment on May 11, 2023, the principal value was reestablished to approximately $13.3 million, and a new fair value was established at approximately $10.94 million. The Second Amendment caused an extinguishment of debt of approximately $1.9 million which includes a loss on revaluation of the debt of $554 thousand and warrant valuation of New Class A and Class B warrants of $1.33 million. In addition, there was a $250 thousand extension fee cash payment that was included within “Other expense, net” on the condensed unaudited consolidated financial statements for the nine months ended September 30, 2023. The Company had approximately $1.05 million of note conversions between May 11, 2023 and September 30, 2023. The Company performed a fair value assessment as of September 30, 2023, and had a debt revaluation loss of approximately $625 thousand. For the three and nine months ended September 30, 2023, the Company had a net loss on debt revaluation and extinguishment of approximately $736 thousand and $2.3 million, respectively.

Following the debt extinguishment on July 19, 2022 as noted further 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. In addition, due to the extinguishment of debt in relation to the Second Amendment on May 11, 2023, the Company needed to perform a fair value analysis as of the date of extinguishment. For the year-ended December 31, 2022 and quarters-ended March 31, 2023, June 2023 and September 30, 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 period ends. The Company determined the fair value of the Convertible Notes uses certain Level 3 inputs.

In accordance with the most favored nation provision (“MFN Provision”), following the issuance of the December 2022 Shares and the December 2022 Warrants, we reduced the conversion price of the October Secured Notes to $19.00 per share. We held a special meeting on March 10, 2023 of our stockholders for the purpose of obtaining stockholder approval for a reduction in the conversion price of the October Secured Notes, subject to a conversion price floor of $7.50 per share, which amount represented the closing price of our Common Stock on the Nasdaq Stock Market on January 3, 2023, the first trading day of the 2023 fiscal year.

In connection with the December 2022 Offering, we also agreed to amend certain existing warrants to purchase up to an aggregate of: (i) 23,681 shares of our Common Stock at an exercise price of $237.50 per share and an expiration date of October 25, 2026; (ii) 40,000 shares of our Common Stock at an exercise price of $87.50 per share and with an expiration date of September 13, 2027; (iii) 40,000 shares of our Common Stock at an exercise price of $112.50 per share and with an expiration date of September 13, 2027; (iv) 40,000 shares of our Common Stock at an exercise price of $137.50 per share and with an expiration date of September 13, 2027; (v) 40,000 shares of our Common Stock at an exercise price of $7.50 per share and an expiration date of September 13, 2027; and (vi) 3,400 shares of Common Stock at an exercise price of $187.50 and an expiration date of January 14, 2025, held by the Noteholders (collectively, the “Noteholder Warrants”) so that the amended Noteholder Warrant would have an exercise price of $19.00 per share. The Company evaluated the warrant exercise price adjustment from the values noted above to $19.00 noting the total dollar value impact in which the Noteholder Warrant’s new fair value, as a result of the exercise price revision, exceeded the previous warrant instrument was approximately $370 thousand, the Company deemed the change in exercise price was in contemplation with the December 2022 offering, as such was recognized as a deferred cost of the offering against the proceeds.

The events of default stated in the Notice of Acceleration and Repossession defined below with NYDIG Financing constituted a cross-default under the terms of secured convertible notes issued to the Noteholders. In addition to such cross-default, the failure of the Company pursuant to the Addendum dated as of July 19, 2022, to escrow an aggregate amount of $950,000 for the benefit of the Noteholders by December 21, 2022, constituted an event of default under the Notes. Due to the defaults noted, the Company did not enter into the second and third tranche of conversions. As such, beginning on November 30, 2022, the Company has been accruing interest of 18% per annum on the outstanding principal amount due to the default which amounted to $617 thousand as of March 10, 2023. On March 10, 2023, the Company entered into a Second Addendum Amendment with the Noteholders, in which the Company paid the accumulated default accrued interest of $617 thousand through the Company’s restricted escrow accounts and contemporaneously with the payment, the Noteholders waived all existing events of default arising under the convertible notes.

Notes payable

On July 13, 2023, the Company entered into two note payable agreements for a total principal value of approximately $235 thousand. The two note payable amounts had a 15% issue discount applied and a maturity date of April 15, 2024. The Company can prepay the note by paying the full amount owed plus an additional 20%. On August 2, 2023 and August 25, 2023, the Company paid both outstanding note payable balances of approximately $235 thousand plus a 20% prepayment fee of approximately $47 thousand. With the prepayment of the notes payable, the Company incurred a $33 thousand loss on debt extinguishment. As of the September 30, 2023, the Company has fulfilled the two note payable agreements.

On December 30, 2021, Soluna MC Borrowing 2021-1 LLC (the “Borrower”), an indirect wholly owned subsidiary of the Company entered into a Master Equipment Finance Agreement (the “Master Agreement”) with NYDIG ABL LLC (“NYDIG”) as lender, servicer and collateral agent (the “NYDIG facility”). The Master Agreement outlined the framework for a financing up to approximately $14.4 million in aggregate equipment financing. Subsequently, the parties negotiated the specific terms of each equipment financing transaction as well as the terms upon which the Noteholders would consent to the transactions contemplated by the Master Agreement.

On January 14, 2022, the Borrower effected an initial drawdown under the Master Agreement in the aggregate principal amount of approximately $4.6 million that bore interest at 14% and was to be repaid over 24 months. On January 26, 2022, the Borrower had a subsequent drawdown of $9.8 million. As part of the transactions contemplated under the Master Agreement, (i) the Company’s indirect wholly owned subsidiary, Soluna MC LLC, formerly EcoChain Block LLC (“Guarantor”), which is the owner of 100% of the equity interests of Borrower, executed a Guaranty Agreement in favor of NYDIG, as lender, dated as of December 30, 2021 (the “Guaranty Agreement”), (ii) Borrower has granted a lien on, and security interest in, all of its assets to NYDIG, as collateral agent, (iii) Guarantor entered into an equipment financing arrangement on assets purchased with the borrowed funds, (iv) Borrower would borrow from NYDIG the loans as forth in certain loan schedules (the “Specified Loans”), and (v) Borrower had executed a Digital Asset Account Control Agreement (the “ACA Wallet Agreement”) with NYDIG, as collateral agent and secured party, and NYDIG Trust Company LLC, as custodian, dated as of December 30, 2021, as well as such other agreements related to the foregoing as mutually agreed (collectively, the “NYDIG Transactions”).

In connection with the NYDIG Transactions, on January 13, 2022, the Company entered into a Consent and Waiver Agreement, dated as of January 13, 2022 (the “Consent”), with the Noteholders, in connection with the October SPA, pursuant to which the Noteholders agreed to waive any lien on, and security interest in, certain assets, provided various contingencies are fulfilled, and each Noteholder who acquired October Secured Notes having a principal amount of not less than $3,000,000 agreed to waive its rights under Section 4.17 of the October SPA to participate in Subsequent Financings (as defined in the October SPA) with respect to the NYDIG Transactions and any additional loans under the MEFA that only finance the purchase of equipment from NYDIG, in order to consent to the NYDIG Transactions. Pursuant to the Consent, the Noteholders also waived the current requirement of the October SPA and the other transaction documents (collectively, the “SPA Documents”) that the Borrower become an Additional Debtor (as defined in the Security Agreement) and execute an Additional Debtor Joinder (as defined in the Security Agreement) for so long as the Specified Loans were outstanding, and NYDIG would not have entered into a subordination or intercreditor agreement with respect to the Guaranty. Further, pursuant to the Consent, the Noteholders waived the right to accelerate the Maturity Date of the October Secured Notes and the right to charge a default rate of interest on such Notes, in each case, with respect to certain changes in names of, and jurisdiction of incorporation, of the Debtors (as defined in the SPA Documents), which waiver would not waive any other Event of Default (as defined in any of the SPA Documents), known or unknown, as of the date of Consent.

Promptly after the date of the Consent, the Company issued warrants to purchase up to 3,400 shares of common stock to the Noteholder holding the largest outstanding principal amount of October Secured Notes as of the date of the Consent. Such warrants were substantially in form similar to the other warrants held by the Noteholders. Such warrants were exercisable for three years from the date of the Consent at an exercise price of $237.50 per share. On December 5, 2022, the exercise price of the warrants were reduced to an exercise price of $19.00 per share, effective with the closing of the Securities Purchase Agreement Offering on December 5, 2022.

The Company, through the Borrower, was required to make average monthly principal and interest payments to NYDIG of approximately $730 thousand on initial drawdown in aggregate principal amount of approximately $4.6 million bearing interest at 14%, and a subsequent drawdown of $9.8 million.

On December 20, 2022, the Borrower received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG with respect to the Master Agreement, by and between Borrower and NYDIG. The obligations of Borrower under the Master Agreement 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.

The NYDIG Notice states that (a) Borrower failed to observe or perform certain covenants, conditions or agreements contained in the Master Agreement 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 Master Agreement, and (b) Borrower defaulted under the guaranty, collateral agreement, or other support agreement, which resulted in an event of default under the Master Agreement. In addition, the NYDIG Notice states that Borrower failed to pay certain payments of principal and interest under the Master Agreement when due, which failure also constituted an event of default under the Master Agreement. As a result of the foregoing events of default, and pursuant to the Master Agreement, NYDIG (x) declared the principal amount of all loans due and owing under the Master Agreement and all accompanying Loan Documents (as defined in the Master Agreement) 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 Master Agreement and the Loan Documents, and (z) demanded the return of all equipment subject to the Master Agreement and the Loan Documents. As such, the principal balance of $10.5 million became due immediately and the Borrower was to bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. Also, as the Company was not able to obtain a waiver, the outstanding deferred financing costs were written off. As of December 31, 2022, the Borrower had incurred accrued interest and penalty of approximately $274 thousand. On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing. As of September 30, 2023, the Company has an outstanding loan balance of approximately $8.0 million and an outstanding accrued interest and penalties of approximately $810 thousand.

Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

The line of credit bears interest at a rate of Prime + 0.75% per annum. Accrued interest is due monthly and principal is due in full following KeyBank’s demand. As of January 1, 2022, the entire line of credit of $1.0 million was drawn and outstanding.

The Company has one class of common stock, par value $0.001 per share. Each share of the Company’s common stock is entitled to one vote on all matters submitted to stockholders. As of September 30, 2023 and December 31, 2022, there were 1,451,988 and 747,837 shares of common stock issued and outstanding, respectively.

Dividends

Pursuant to the Certificate of Designations, Preferences and Rights of 9.0% Series A Cumulative Perpetual Preferred Stock of the Company, dividends, when, as and if declared by the Board (or a duly authorized committee of the Board), will be payable monthly in arrears on the final day of each month, beginning August 31, 2021. During the year ended December 31, 2022, the Board declared and paid the Company aggregate dividends on the shares of Series A Preferred Stock of approximately $3.9 million, respectively. The Board of Directors had not declared any Series A Preferred Stock dividends beginning October 2022 through the date of this report, as such the Company has accumulated approximately $1.7 million of dividends in arrears on the Series A Preferred Stock through December 31, 2022. An additional $5.2 million of dividends in arrears on the Series A Preferred Stock has been accumulated for a total of approximately $6.9 million in dividend in arrears.

The Company’s Series B Preferred Stock includes a 10% accruing dividend compounded daily for 12 months from the original issue date of July 20, 2022 that may be paid in cash or stock at the Company’s option at the earlier of (i) the date the Series B Preferred Stock is converted, or (ii) the Series B Dividend Termination Date. On August 11, 2023, Soluna Holdings, Inc. (the “Company”) paid a mandatory dividend on its outstanding Series B Convertible Preferred Stock in the amount of approximately $657 thousand. Pursuant to the Certificate of Designation for the Series B Stock, the Company had the option to pay the dividend in cash or shares of Common Stock. Pursuant to a Dividend Payment Agreement, the Company and the holder of the Series B Stock agreed to satisfy the payment of the dividend through the issuance of 44,000 shares of its Common Stock and 70,300 prefunded warrants (the “Prefunded Warrants”).

Each Pre-Funded Warrant has been funded to the amount of $.19999, with $0.00001 per share of common stock payable upon exercise, is immediately exercisable, may be exercised at any time until exercised in full and is subject to customary adjustments. The Pre-Funded Warrants may not be exercised if the aggregate number of shares of the Company’s common stock beneficially owned by the holder (together with her affiliates) would exceed 4.99% of the Company’s outstanding Common Stock immediately after exercise. However, the holder may increase (upon 61 days’ prior notice from the holder to the Company) or decrease such percentages, provided that in no event such percentage exceeds 4.99%.

Reservation of Shares

The Company had reserved common shares for future issuance as follows as of September 30, 2023:

Stock options outstanding (1)	52,392
Restricted stock units outstanding	11,907
Warrants outstanding (1)	1,230,130
Common stock available for future equity awards or issuance of options (1)	412,337
Number of common shares reserved	1,706,766

(1) Prior period results have been adjusted to reflect the Reverse Stock Split of the Common Stock at a ratio of 1-for-25 that became effective October 13, 2023. See Note 2, “Basis of Presentation,” for details.

The Company also notes that as of September 30, 2023, there are 1,100,839 Series A preferred stock available for future equity awards under the 2021 Plan.

Income (Loss) per Share

The Company computes basic income (loss) per common share by dividing net income (loss) by the weighted average number of common shares outstanding during the reporting period. Diluted income (loss) per share reflects the potential dilution, if any, computed by dividing income (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.

The Company notes as continuing operations was in a net loss for the three and nine months ended September 30, 2023 and 2022, as such basic and diluted earnings per share is the same balance as continuing operations acts as the control amount in which would cause antidilution. Not included in the computation of earnings per share, assuming dilution, for the three and nine months ended September 30, 2023, were options to purchase 52,392 shares of the Company’s common stock, 11,907 outstanding restricted stock units, and 1,230,130 outstanding warrants not exercised. These potentially dilutive items were excluded because the calculation of incremental shares resulted in an anti-dilutive effect.

Not included in the computation of earnings per share, assuming dilution, for the three and nine months ended September 30, 2022, were options to purchase up to 32,493 shares of the Company’s common stock, 32,292 outstanding restricted stock units, outstanding warrants to purchase up to 303,312 shares of common stock, and shares of common stock issuable upon the conversion of a portion of the October Secured Notes pursuant to the Addendum. These potentially dilutive items were excluded because the calculation of incremental shares resulted in an anti-dilutive effect.

Contingencies:

Spring Lane Capital Contingency

The Company has a potential contingency associated with an agreement with Spring Lane of up to $250 thousand which would be reduced by a proportion of funding received from Spring Lane up to the $35.0 million aggregate contribution cap. The Company considers the probability of a payment for the contingency to be remote.

Legal

We are subject to legal proceedings, claims and liabilities which arise in the ordinary course of business. When applicable, we accrue for losses associated with legal claims when such losses are probable and can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. Legal fees are charged to expense as they are incurred.

The Company has been named as a party in the December 19, 2019 United States Environmental Protection Agency (“EPA”) Demand Letter regarding the Malta Rocket Fuel Area Superfund Site (“Site”) located in Malta and Stillwater, New York in connection with an alleged release of hazardous materials into the environment. The EPA is seeking reimbursement of response costs from all named parties in the amount of approximately $358 thousand plus interest in connection with the investigation and disposal activities associated with the various drum caches discovered at the Site, issuance of the Explanation of Significant Differences (“ESD”) of the Site, and implementation of the work contemplated by the ESD. The Company considers the likelihood of a material adverse outcome to be remote and does not currently anticipate that any expense or liability it may incur as a result of these matters in the future will be material to the Company’s financial condition.

NYDIG filed a complaint against a subsidiary of Company, Soluna MC Borrowing 2021-1, LLC (“Borrower”) and Soluna MC, LLC, as Guarantor (“Guarantor”), and together with Borrower, (“NYDIG Defendants”) in Marshall Circuit Court of the Commonwealth of Kentucky on December 29, 2022 regarding a series of loans made by NYDIG to Borrower pursuant to a master equipment finance agreement that were secured by certain assets of Borrower and guaranteed by Guarantor pursuant to a written guaranty agreement executed by Guarantor. The Court issued on February 15, 2023 an agreed order granting NYDIG’s motion for writ of possession which, among other things, ordered parties to provide NYDIG access to the collateral described therein and preserved the rights of NYDIG to pursue a deficiency judgment against the NYDIG Defendants. Also on February 15, 2023, the NYDIG Defendants filed their answer and affirmative defenses in this proceeding. The NYDIG Defendants believe that NYDIG has liquidated some of the collateral securing the loans and anticipate that NYDIG will complete the liquidation of collateral and continue to prosecute the complaint to obtain a judgment against the NYDIG Defendants. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. NYDIG filed a motion to dismiss in response to SCI’s declaratory judgment complaint on April 13, 2023. SCI filed a response in opposition to NYDIG’s motion to dismiss on April 27, 2023. The court heard oral arguments on May 16, 2023. On June 22, 2023, the court issued an order granting NYDIG’s motion to dismiss, on the basis that the case was not ripe for decision, without prejudice. SCI intends to continue to vigorously defend any allegations regarding liability on account of NYDIG Defendants’ debts and liabilities to NYDIG under their loan documents and intends to refile a declaratory judgment complaint against NYDIG.

On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the three months ended September 30, 2023. The NYDIG Defendants noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the NYDIG Defendants are currently disputing.

In September 2023, Atlas Technology Group LLC (“Atlas”) filed a complaint against Soluna MC LLC (formerly EcoChain Block LLC) (“Soluna MC”), Soluna Computing, Inc., and Soluna Holdings, Inc. (collectively, the “Atlas Defendants”) in the Supreme Court of the State of New York, County of New York regarding a co-location services agreement between Soluna MC and Atlas.  Atlas alleges that the termination of such agreement by Soluna MC was a breach and asserts various claims, including breach of contract and the return of pre-paid fees. The claim requests a judgement against the Atlas Defendants for the return of pre-paid fees of approximately $464 thousand and additional damages to be determined at trial of not less than $7.9 million, and reimbursement of costs including legal fees and other costs. The complaint also contains references to alter ego liability and piercing the corporate veil.  The Atlas Defendants believes they have substantial factual and legal defenses to these claims and intend to defend the claims vigorously.

The referenced pre-paid fees of approximately $464 thousand have been reported in previous filings on Soluna MC’s balance sheet. No reserves have been established for any other claims asserted in such complaint.

During the three and nine months ended September 30, 2022, the Company incurred $1 thousand and $2 thousand, respectively. A partner at Couch White, LLP is an immediate family member of one of our Directors.

HEL Transactions

As discussed above, on October 29, 2021, the Company 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, (B) SHI issued to HEL the Termination Shares, and (C) HEL and SHI entered into an Amended and Restated Contingent Rights Agreement that, among other things, amended the existing Contingent Rights Agreement by and between HEL and SHI, dated January 13, 2020, to provide SHI the right to invest directly in certain cryptocurrency mining opportunities being pursued by HEL. SHI filed a registration statement with the SEC to register the resale of the Termination Shares on February 14, 2022.

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 Merger Shares were issued on May 26, 2023 and 39,600 Merger Shares were issued on October 10, 2023. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 59,400 Merger Shares, a total of 59,400 Merger Shares remain available for possible issuance pursuant to the terms of the Merger Agreement.

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.

Four of the Company’s directors have various affiliations with HEL.

Michael Toporek, the former Chief Executive Officer, and current Executive Director of the Company, 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 nine months ended September 30, 2023 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.

The Company’s investment in HEL was initially carried at the cost of investment and was $750 thousand. Based on evaluation of projections for the Company’s investment in HEL, the Company fully impaired the equity investment of $750 thousand as of December 31, 2022, writing it down to $0.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of September 30, 2023 and December 31, 2022. The Company may enter into additional transactions with HEL in the future.

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% of the shares of our Common Stock outstanding on the measurement date. Subject to certain adjustments as provided in the 2023 Plan, the maximum aggregate number of shares of our Common Stock that may be issued under the 2023 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), 9.75% 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 2023 Plan, (i) shares of our Common Stock subject to the 2023 Plan shall include shares of our Common Stock which revert back to the 2023 Plan in a prior quarter pursuant to the paragraph below, and (ii) the number of shares of our Common Stock that may be issued under the 2023 Plan may never be less than the number of shares of our Common Stock that are then outstanding under (or available to settle existing) 2023 Plan Award grants.

In the event that, prior to the date this Plan shall terminate, any Award granted under this Plan expires unexercised or unvested or is terminated, surrendered or cancelled without the delivery of Common Shares, or any shares of Restricted Stock are forfeited back to the Company, then the Common Shares subject to such Award may be made available for subsequent Awards under the terms of this Plan. As used in this Plan, “Specified Awards” shall mean (i) Awards to Eligible Persons who are not employed or engaged by the Company or any of its subsidiaries as of the last day of any fiscal quarter of the Company, commencing with the fiscal quarter ending March 31, 2023 and (ii) Awards that have a grant date at least three (3) years prior to the last day of any fiscal quarter of the Company, commencing with the fiscal quarter ending March 31, 2023.

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.

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.

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.

During the three months ended September 30, 2023, the Company did not issue any equity awards under its 2021 or 2023 Plans.

During the nine months ended September 30, 2023, the Company awarded 20,000 restricted stock units under the 2021 Plan, valued at $7.465 per share based on the closing market price of the Company’s common stock on the date of the grant. The restricted stock units vested during May 2023.

Accounting Changes and Error Corrections [Abstract]

Effect of Recent Accounting Updates

13. Effect of Recent Accounting Updates

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 in fiscal year 2023 and properly record and disclose in relation to Topic 326.

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 its adoption of new accounting pronouncements or changes to its significant accounting policies that were disclosed in its condensed unaudited consolidated financial statements for the three and nine months ended September 30, 2023.

As described in Note 1, the Company entered into a Stock Purchase Agreement with Purchaser, pursuant to which the Company sold on April 11, 2022 all of the issued and outstanding shares of capital stock of its wholly-owned subsidiary, MTI Instruments for approximately $9.0 million in cash, net of transaction costs. For fiscal year 2022 and 2023, our Instrumentation business segment was classified as discontinued operations in our financial statements for all periods presented. The Company incurred approximately a $7.5 million pretax gain on sale of MTI Instruments for the year ended December 31, 2022, in which they did not receive until the second quarter of fiscal year 2022. The Company’s condensed consolidated balance sheets and condensed consolidated statements of operations report discontinued operations separate from continuing operations. The Company’s condensed consolidated statements of equity and statements of cash flows combine continuing and discontinued operations.

As described in Note 1, the Company entered into a Stock Purchase Agreement with Purchaser, pursuant to which the Company sold on April 11, 2022 all of the issued and outstanding shares of capital stock of our wholly-owned subsidiary, MTI Instruments for an all-cash purchase price of $10.75 million, subject to working capital and certain other adjustments as set forth in the Stock Purchase Agreement. The purchase price did not include specified debt of MTI Instruments, which is the responsibility of the Company. This debt was transferred to the Purchaser at the date of Sale and is included in the closing balance sheet as shown below, which resulted in a reduction in the consideration payable to the Company.

PROJECT MARIE

15. PROJECT MARIE

As previously disclosed in Footnotes 4 and 8, 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 million became due immediately and the Borrower was to bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. As of September 30, 2023, the Company reduced the outstanding debt by the repossessed collateralized assets net book value of $3.4 million less accrued interest that was paid off first when the collateral was repossessed of approximately $560 thousand and legal fees of approximately $251 thousand, reducing the debt outstanding to approximately $8.0 million as of September 30, 2023. Also, as the Company was not able to obtain a waiver, the outstanding deferred financing costs were written off. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the quarter. The Company noted a difference of approximately $500 thousand in the ending principle, interest and penalties balance as of August 3, 2023 valuation date indicated in the letter, which the Company is currently disputing. As of September 30, 2023 and December 31, 2022, the Borrower had incurred accrued interest and penalty of approximately $810 thousand and $274 thousand.

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 million in which were written off the Company’s books for the nine months ended September 30, 2023, with an offset accrued interest to date when repossessed, a loss on sale of fixed assets, and to the outstanding loan. Additionally, NYDIG has stated its intention to pursue SCI, the parent company of Guarantor, under a piercing of the corporate veil claim relating to NYDIG Defendants’ debts and liabilities under the loan documents. SCI denies any such liability and has filed a complaint for a declaratory judgment against NYDIG in the Eighth Judicial District Court in Clark County, Nevada on March 16, 2023 seeking a declaratory judgment as to such matter. In a related development, also on February 23, 2023, the Borrower received a notice of termination of the Management and Hosting Services Agreement with CC Metals and Alloys, LLC. As a result of this action and certain other characteristics of the facility, the Company elected to shut down the Marie facility. The Company believes it will maximize its profits and return on assets by concentrating its personnel and capital on its Dorothy Facility.

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 million of equipment and leasehold approvements associated with Project Marie that were not attached with the repossession of NYDIG collateralized assets were impaired as of the year-ended December 31, 2022.

For the three and nine months ended September 30, 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:

VARIABLE INTEREST ENTITY

16. VARIABLE INTEREST ENTITY

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 million to fund certain projects to develop green data centers co-located with renewable energy assets (the “Spring Lane Commitment”). We anticipate that these capital contributions, once deployed into the projects, will help develop up to three behind-the-meter (BTM) projects designed to convert wasted renewable energy into clean computing services such as Bitcoin mining and artificial intelligence. The Bilateral Contribution Agreement outlines the framework for the Spring Lane Commitment; however, neither we nor Spring Lane are obligated to complete any projects under such agreement and any actual capital contributions are subject to various conditions precedent, including the receipt of requisite lender and other consents, acceptance by Spring Lane of specific projects and negotiations of agreements regarding those projects, including milestones and structure. In partial consideration of the amendment to the October Secured Notes discussed above, the investors agreed to release certain collateral covered by their security agreement to permit the Company to proceed forward with the initial phase of Project Dorothy, which we expect to be partially funded by Spring Lane, which the Company expects to complete in the near future.

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 the first 25 MW of 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 million to DVSL (the “Company Commitment”), and on August 5, 2022, the Company was deemed to have contributed approximately $8.1 million, through payment of capital expenditures and development costs made on behalf of DVSL by the Company prior to August 5, 2022. Further under the Agreement, Spring Lane committed to a capital contribution of up to $12.5 million to DVSL (the “Spring Lane Dorothy Commitment”), and as of December 31, 2022, Spring Lane contributed approximately $4.8 million. Under the Dorothy Contribution Agreement, the Company and Spring Lane have committed to make subsequent contributions, up to their respective Company Commitment and Spring Lane Dorothy Commitment amounts, on a pro rata basis, upon receipt of a contribution request from DVSL, as set forth in the Dorothy Contribution Agreement and subject to the satisfaction of certain conditions described therein. The proceeds of any subsequent commitments will be applied to pay project costs in accordance with the project budget.

In exchange for their contributions, the Company and Spring Lane were issued 67.8% and 32.2% of the Class B Membership Interests in DVSL, respectively, and were admitted as Class B members of DVSL. Further pursuant to the Agreement, DVSL issued 100% of its Class A Membership Interests to Devco. The Dorothy Contribution Agreement contains customary indemnification provisions, liquidation provisions and governance provisions with respect to DVSL. The Parties also entered into an Amended and Restated Limited Liability Company Agreement of DVSL providing for the governance of DVSL.

Soluna evaluated this legal entity under ASC 810, Consolidations and determined that DVSL is a variable interest entity that should be consolidated into Soluna, with a non-controlling interest recorded to account for Spring Lane’s equity ownership of the Company. Soluna has a variable interest in DVSL. The entity was designed by Soluna to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in Soluna, through its equity interest in DVSL, absorbing operational risk that the entity was created to create and distribute, resulting in Soluna having a variable interest in DVSL.

On March 10, 2023, the Company along with Devco, and Soluna DVSL ComputeCo, LLC, a Delaware limited liability company (the “Project Company”) entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”) with Soluna SLC Fund I Projects Holdco, LLC, a Delaware limited liability company (“Spring Lane”) that is wholly owned indirectly by Spring Lane Management LLC. The Project Company is constructing a modular data center with a peak demand of 25 megawatts (the “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 $7,500,000 (the “Sale”). After giving effect to the Sale, the Company owned 6,790,537 Class B Membership Interests (constituting 14.6% of the Class B Membership Interests) and Spring Lane owns 39,791,988 Class B Membership Interests (constituting 85.4% of the Class B Membership Interests). The cash portion of the purchase price paid by Spring Lane to the Company was $5,770,065, which represented the purchase price of $7,500,000 less the Company’s pro rata share of certain contributions funded entirely by Spring Lane in the earlier portion of this series of transactions occurring during February 2023 and March 2023. As a further part of these transactions, the parties agreed that from January 1, 2023 onwards, Soluna would bear only 14.6% of the costs relating to the construction and operation of the Dorothy Phase 1A Facility, compared to its 67.8% share until that time, including during the calendar year 2022. After Spring Lane Capital realizes an 18% 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.

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”), an amendment and restatement of the Third Amended and Restated Limited Liability Company Agreement of the Project Company dated as of March 3, 2023, and (b) the Amended and Restated Contribution Agreement, dated as of March 10, 2023 (the “A&R Contribution Agreement”), an amendment and restatement of the Contribution Agreement dated as of August 5, 2022. The Fourth A&R LLCA provides for certain updates in respect of Spring Lane’s majority ownership. The A&R Contribution Agreement reflects updated pro rata member funding percentages as a result of the Sale as well as updated contribution caps for each of the Company and Spring Lane.

As of January 1, 2023, there were no changes in the Limited Liability Agreement of the Company other than those related to incorporating the new investment and the purpose and design of the Company has not changed. 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.

The carrying amount of the VIE’s assets and liabilities was as follows for DVSL:

(Dollars in thousands)	September 30, 2023		December 31, 2022
Current assets:
Cash and restricted cash	$	894	$	15

Effective, January 1, 2023, the Company’s ownership in DVSL was reduced from 67.8% to 14.6%; see above for details.

On May 9, 2023, the Company’s indirect subsidiary Soluna DV ComputeCo, LLC (“DV”) completed a strategic partnership and financing with a special purpose vehicle, Navitas West Texas Investments SPV, LLC, (“Navitas”) organized by Navitas Global, to complete the second phase of the Dorothy Project (“Dorothy 1B”). Under a Contribution Agreement among the parties, the Company owned a substantially complete 25MW data center under construction, in which 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 $4,500,000 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 $7,596,970 and receipt of an additional 7,597 Membership Interests, for a total of 12,097 Membership Interests and 49% ownership of the Company, and (ii) Soluna’s additional capital contribution of $1,340,000 and receipt of an additional 1,340 Membership Interests, for a total of 12,590 Membership Interests and 51% ownership of the Company, and (b) describe the respective rights and obligations of the Members and the management of the Company.

Soluna evaluated this legal entity under ASC 810, Consolidations and determined that DV is a variable interest entity that should be consolidated into Soluna, with a non-controlling interest recorded to account for Navita’s equity ownership of the Company. Soluna has a variable interest in DV. The entity was designed by Soluna to create an entity for outside investors to invest in specific projects. The creation of this entity resulted in Soluna, through its equity interest in DV, absorbing operational risk that the entity was created to create and distribute, resulting in Soluna having a variable interest in DV.

DV is a variable interest entity of Soluna due to DV being structured with non-substantive voting rights. This is due to two factors being met as outlined in ASC 810-10-15-14 that require the Variable Interest Entity model to be followed.

a.	The voting rights of Soluna are not proportional to their obligation to absorb the expected losses of the legal entity. Soluna gave Navitas veto rights over significant decisions, which results in Soluna having fewer voting rights than their obligation to absorb the expected losses of the legal entity.
b.	Substantially all of DV’s activities are conducted on behalf of Soluna, who has disproportionally fewer voting rights.

Also, Soluna is the primary beneficiary due to having the power to direct the activities of DV that most significantly impact the performance of the Company due to its role as the manager handling the day-to-day activities of DV as well as majority ownership of and has the obligation to absorb losses or gains of DV that could be significant to Soluna.

Accordingly, the accounts of DV are consolidated in the accompanying unaudited condensed financial statements

The carrying amount of the VIE’s assets and liabilities was as follows for DV:

Segment Reporting [Abstract]

Segment Information

17. Segment Information

The Company applies ASC 280, Segment Reporting, in determining its reportable segments. The Company has two reportable segments: Cryptocurrency Mining and Data Hosting. The Company notes that previously there was an additional segment: Test and Measurement Instrumentation, however as discussed in Note 1, the Company sold MTI Instruments in April 2022, and therefore has classified as discontinued operations. The guidance requires that segment disclosures present the measure(s) used by the Chief Operating Decision Maker (“CODM”) to decide how to allocate resources and for purposes of assessing such segments’ performance. The Company’s CODM is comprised of several members of its executive management team who use revenue and cost of revenues of both reporting segments to assess the performance of the business of our reportable operating segments.

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.

For the three months ended September 30, 2023 and 2022, approximately 0% and 4% of the Company’s cryptocurrency mining revenue was generated from Project Edith (data center located in Wenatchee, Washington), 0% and 37% from Project Marie, 3% and 59% from Project Sophie (data center located in Murray, Kentucky), and 97% and 0% from Project Dorothy (data center located in Texas), respectively. 0% and 100% of the Company’s data center hosting revenue was generated from Project Marie from hosting with customers for the three months ended September 30, 2023 and 2022, 25% and 0% of the data hosting revenue for three months ended September 30, 2023 and 2022 was generated from Project Sophie, and 75% and 0% of the data hosting revenue for the three months ended September 30, 2023 and 2022 was generated from Project Dorothy (data center located in Texas).

For the nine months ended September 30, 2023 and 2022, approximately 0% and 6% of the Company’s cryptocurrency mining revenue was generated from Project Edith (data center located in Wenatchee, Washington), 14% and 41% from Project Marie, and 54% and 53% from Project Sophie (data center located in Murray, Kentucky) and 32% and 0% from Project Dorothy (data center located in Texas), respectively. 5% and 100% of the Company’s data center hosting revenue was generated from Project Marie from hosting with customers for the nine months ended September 30, 2023 and 2022, 31% and 0% of the data hosting revenue for nine months ended September 30, 2023 and 2022 was generated from Project Sophie, and 64% and 0% of the data hosting revenue for the nine months ended September 30, 2023 and 2022 was generated from Project Dorothy (data center located in Texas) for the nine months ended September 30, 2023 and 2022.

The Company evaluates performance based on profit or loss from operations before income taxes, accounting changes, items management does not deem relevant to segment performance, and interest income and expense. Inter-segment sales and expenses are not significant. Non-cash items of depreciation and amortization are included within both costs of sales and selling, general and administrative expenses.

The following table details revenue and cost of revenues for the Company’s reportable segments for three and nine months ended September 30, 2023 and 2022, and reconciles to net income (loss) on the consolidated statements of operations:

Reverse Stock Split

On October 11, 2023, the Company filed a 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. The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023. The reverse stock split was approved by the Board of Directors and by shareholders at the annual meeting of the stockholders on June 29, 2023. At the effective time, 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 Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole share.

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 per share (the “Series B Preferred Stock”), may be converted to Common Stock. The total number of shares of Series B Preferred Stock of the Company authorized for issuance remained at 187,500.

Reverse Stock Split

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 (the “Reverse Split”). The Company’s common stock began trading on a post-split basis under the Company’s existing trading symbol, “SLNH,” when the market opened on October 16, 2023. The reverse stock split was approved by the Board of Directors and by shareholders at the annual meeting of the stockholders on June 29, 2023. At the effective time, 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 Reverse Split did not change the number of shares of common stock authorized for issuance. No fractional shares were outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock was automatically entitled to receive an additional fraction of a share of common stock to round up to the next whole 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 for continued listing on the Nasdaq. On October 30, 2023, the Company received a notice of compliance from NASDAQ.

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 per share (the “Series B Preferred Stock”), may be converted to Common Stock. The total number of shares of Series B Preferred Stock of the Company authorized for issuance remained at 187,500.

The effects of the Reverse Stock Split have been reflected in these condensed unaudited consolidated 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 and Restricted Cash

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of less than three months. As of September 30, 2023 and December 31, 2022, the Company had approximately $5.6 million and $1.1 million within cash and cash equivalents. In addition, for cash flow purposes, the Company had approximately $1.1 million as of September 30, 2022 within cash and cash equivalents.

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, 2023, the Company had restricted cash of approximately $4.4 million, in which $3.4 million was classified as current and $1.0 million was classified as non-current. On December 31, 2022, the Company had restricted cash of approximately $685 thousand, in which the entire balance was classified as current. The Company notes that there was no restricted cash balance as of September 30, 2022 for cash flow purposes. The balance in restricted cash relates to funds held in escrow accounts due to sales of equipment that were executed, in which the Company can release to the convertible noteholders only if they request their share of funds. If no funds are distributed to the convertible noteholders from the escrow account by December 31, 2023, the funds may be used for general purposes for the Company. In addition, there was a restricted deposit held with a customer that was for less than 12 months. The Company has a long term restricted cash balance in relation to a collateralized deposit.

Deposits and credits on equipment

Deposits and credits on equipment

As of September 30, 2023 and December 31, 2022, the Company had approximately $975 thousand and $1.2 million in deposits and credits on equipment, that had not yet been received by the Company as of the year end. Once the Company receives such equipment in the subsequent period, the Company will reclassify such balance into Property, Plant, and Equipment. The credit on equipment is restricted to be used on future purchases by March 1, 2024 (“expiration date”). The Company notes that if an order is not executed by the expiration date, the credit would be forfeited. The Company intends to utilize the full credit balance for future orders prior to the expiration date.

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.

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.
