HEL Transactions
As discussed in the Company’s 2023 Annual Report and all agreements included as exhibits and defined within the 2023 Annual Report, on October 29, 2021, the Company completed the Soluna Callisto acquisition pursuant to the merger agreement (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 Harmattan Energy, Ltd. (“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 thousand, (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, 39,600 Merger Shares were issued on October 10, 2023, and 17,820 Merger Shares were issued on October 8, 2025. On February 6, 2026, the Company issued an additional 10,692 Merger Shares, due to the 18 MW of energization being met. 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. The remaining 30,888 Merger Shares were issued on June 24, 2026 with the energization of D2, and therefore closes out the 118,800 Merger Shares available for issuance, and no further Merger Shares remain available pursuant to the terms of the Merger Agreement as of June 30, 2026.

Four of the Company’s directors have various affiliations with HEL. The Company notes that the only transaction with HEL for the year ended December 31, 2025 and three and six months ended June 30, 2026 was in relation to the issuance of Merger Shares noted above.
The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of June 30, 2026 and December 31, 2025. The Company’s equity investment of HEL was fully impaired in fiscal year 2024, as such the equity investment is valued at $0 for both June 30, 2026 and December 31, 2025. The Company may enter into additional transactions with HEL in the future.
