CleanSpark (Nasdaq: CLSK) is a large-scale digital infrastructure developer that owns and operates a multi-gigawatt portfolio of energy-backed data center campuses across the United States.

About CleanSpark
CleanSpark is a market-leading data center developer with a national portfolio spanning six U.S. states, including Georgia, Texas, Tennessee, Wyoming, Nevada, Mississippi, and Utah. The company controls power, land, and data centers, monetizing low-cost, high-reliability energy to produce compute — both for Bitcoin mining and increasingly for AI workloads. Its operating model follows a repeatable infrastructure-first process: procuring scalable energy, building data center capacity on schedule and budget, transforming power into compute capacity, and reinvesting capital to expand margins. CleanSpark reports metrics such as 1.8 GW of power under contract, 50 EH/s operational hashrate, and over 13,000 Bitcoin in holdings. Its primary stakeholders are shareholders and investors, as a Nasdaq-listed public company, and it serves the emerging demand for AI data center compute capacity in addition to its established Bitcoin mining operations.
