Mines 668 bitcoin in December and 7,024 bitcoin in 2024

287.9% hashrate growth with 33.3% efficiency improvement year over year

LAS VEGAS, Jan. 6, 2025 /PRNewswire/ -- CleanSpark Inc. (Nasdaq: CLSK), America's Bitcoin Miner (the "Company"), today released its unaudited bitcoin mining and operations update for the month ending December 31, 2024.

"2024 marked a transformative year for CleanSpark, where we achieved true escape velocity in our industry," said Zach Bradford, CEO and President of CleanSpark. "We have firmly established ourselves as a U.S. leader in operational hashrate, cost-efficiency, fleet performance, bitcoin treasury management, and portfolio-wide uptime. Surpassing our year-end guidance, we reached an impressive 39.1 EH/s and enhanced fleet efficiency to under 17.6 J/Th ahead of schedule. We strategically expanded into three new states—Mississippi, Tennessee, and Wyoming—while completing multiple site expansions. Notably, we crossed a historic milestone by mining our 20,000th bitcoin, a testament to our operational excellence since mining our first bitcoin just four years ago. With the successful closing of a $650 million zero-coupon convertible bond offering in December, we are fully equipped to execute our strategic objectives. As we gear up to achieve 50 EH/s by mid-2025, our growth strategy is not only ambitious but fully funded, positioning CleanSpark to lead the industry into its next phase of innovation and scale."
