CleanSpark is a data center developer, until recently focused exclusively on bitcoin mining. We independently own, lease and operate a large portfolio of data centers and power assets across the United States with locations in Georgia, Tennessee, Mississippi and Wyoming for a total contracted power capacity of approximately 1,027 megawatts (“MW”) as of September 30, 2025. We intend to continue our growth in these regions and are actively developing plans for additional capacity in these states and other domestic regions. We have no intention to mine, purchase or hold any crypto assets other than bitcoin at this time or in the foreseeable future, and we did not hold any other crypto asset as of September 30, 2025.7 From its latest annual report
