CleanSpark, Inc. (CLSK) files its annual report describing a fast-growing bitcoin mining and data center platform that is beginning to diversify into AI and high‑performance computing (HPC) hosting. The company controls approximately 1,027 MW of contracted power capacity across Georgia, Tennessee, Mississippi and Wyoming, supporting an operational hashrate of 45.6 EH/s as of September 30, 2025.
CleanSpark reports ownership of about 336,544 miners, with roughly 241,934 in service and average energy efficiency of 16.7 W/TH. For the year ended September 30, 2025, it mined approximately 7,873 bitcoins, net of pool fees, versus 7,092 in the prior fiscal year, while increasingly using mined bitcoin to fund operations, capital spending and derivative‑based treasury strategies.
The company is pivoting part of its footprint toward AI and HPC data centers, including hiring a Senior Vice President of AI Data Centers, signing a non‑binding collaboration with Submer for immersion‑cooled AI infrastructure, and acquiring 271 acres in Austin County, Texas with long‑term power agreements totaling 285 MW for a next‑generation campus. Management highlights significant regulatory, capital, execution and market risks around both bitcoin mining and the new AI/HPC initiatives.
