LAS VEGAS, Sept. 18, 2026 /PRNewswire/ -- CleanSpark, Inc. (NASDAQ:CLSK) ("CleanSpark" or the "Company"), a market-leading data center developer, today announced that its wholly owned subsidiary, CSDC Finance I, LLC (the "Issuer"), has priced a $2.276 billion offering of 7.875% senior secured notes due 2031 (the "Notes") at a price equal to 98.500% of their principal amount. The Notes will be sold in a private offering to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the "Securities Act") and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The offering is expected to close on September 25, 2026, subject to customary closing conditions.

The Issuer intends to use the net proceeds from the offering (a) to finance the remaining cost of the build out of the data center (the "Sandersville Facility"), (b) to reimburse the Company for certain prior equity contributions made in respect of the Sandersville Facility, and (c) to fund debt service reserves.

The Notes will be fully and unconditionally guaranteed by CSRE Properties Sandersville, LLC, a wholly owned direct subsidiary of the Issuer ("CSRE Properties"). The notes and related note guarantee will be secured by first-priority liens on (i) substantially all assets of the Issuer and CSRE Properties, other than certain excluded property, and (ii) all equity interests of the Issuer held by CSDC Holdings I, LLC, a Delaware limited liability company and the direct parent company of the Issuer.

CleanSpark will provide a customary completion guarantee with respect to the Sandersville Facility, under which it will fund the Issuer as necessary to ensure the timely completion of the Sandersville Facility in the event that the proceeds of the Notes are insufficient to do so.

The offering is subject to market and other conditions, and there can be no assurance as to whether, when or on what terms the offering may be completed.

The Notes have not been registered under the Securities Act or securities laws of any other jurisdiction, and the Notes may not be offered or sold in the United States absent registration or an applicable exemption from registration under the Securities Act and any applicable state securities laws. The Notes were offered only to persons reasonably believed to be qualified institutional buyers under Rule 144A under the Securities Act and outside the United States to non-U.S. persons in reliance on Regulation S under the Securities Act.

This press release shall not constitute an offer to sell, or a solicitation of an offer to buy the Notes, nor shall there be any sale of the Notes in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
