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, batchable computing applications, such as artificial intelligence and machine learning, with the goal of providing a cost-effective alternative to battery storage or transmission lines.

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. Project Sophie currently operates fully on proprietary mining with a capacity of 25 megawatts. 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. We have a development site in Texas (“Project Dorothy”) for a potential of up to 100 megawatts to be built at a wind farm with initial energization of 50 megawatts, in which the Company has obtained approval from the ERCOT and expects to begin energization in fiscal year 2023.

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.

As shown in the accompanying financial statements, the Company did not generate sufficient revenue to generate net income and has negative working capital as of December 31, 2022. In addition, the Company has seen a decline in the price of Bitcoin, especially in the second and third quarters of fiscal year 2022 due its volatility, which had a material and negative impact to our operations, however, did some improvement in the fourth quarter of 2022.

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.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">In addition, as discussed above and further in Notes 16, and 17, the Company sold the MTI Instruments business in April 2022 to focus on developing and monetizing green, zero-carbon computing and cryptocurrency mining facilities.
