Company achieves 50 EH/s mid-year target

12,608 BTC treasury, all self-mined

LAS VEGAS, July 7, 2025 /PRNewswire/ — CleanSpark, Inc. (Nasdaq: CLSK), America’s Bitcoin Miner® (the “Company”), today released its unaudited Bitcoin mining and operations update for the month ended June 30, 2025. 

“June 2025 marked a milestone month for CleanSpark,” said Zach Bradford, CEO and President. “We achieved our mid-year target of reaching 50 EH/s of operational hashrate, becoming the first Bitcoin miner to do so entirely through fully self-operated infrastructure. This represents a 9.6% month-over-month increase which further improved our fleet’s energy efficiency to 16.15 J/Th. I want to express my gratitude to our team, especially our COO Scott Garrison and CTO Taylor Monnig, for their grit and leadership. Under their direction, the tireless efforts of our operations and technology teams resulted in the addition of over 10 EH/s of capacity across four states to achieve the ambitious target. With the talent, infrastructure and power contracts in place, CleanSpark is well-positioned to continue scaling.”

“With 179 megawatts of additional power capacity secured under contract, enough to support more than 10 EH/s of incremental hashrate, we are actively expanding our infrastructure to bring it online. This capacity will power additional deployments designed to drive efficient, sustainable growth. These expansion efforts are the result of deliberate planning and execution across energy procurement, engineering, and site development. And it’s only the beginning. We also have a substantial pipeline of additional power under development and research, giving us a clear path into CleanSpark’s next phases of long-term, scalable growth.”

As the only large-scale, pure play vertically integrated Bitcoin miner, CleanSpark continues to set the standard for operational excellence and strategic discipline. The Company now holds a bitcoin treasury of 12,608 BTC, ranking seventh among all publicly traded companies worldwide¹, all generated entirely through self-mining.

“CleanSpark’s Digital Asset Management efforts are now live and in the ‘crawl phase,” said Gary A. Vecchiarelli, CFO. “Our initial strategies went live, and we are seeing positive proof of concept results in our actively managed spot sales program and derivative overlay. June resulted in an average sale price of $105,860 per bitcoin net of customary fees, which is $446 above VWAP for the same period, not including the premiums received from derivative transactions. While these strategies are still evolving, I’m proud of the institutional-grade discipline and performance our treasury team is already demonstrating.”

“This is a pivotal moment for Bitcoin,” Bradford added. “Corporations around the globe are embracing the value of a Bitcoin-enhanced balance sheet. In fact, corporate Bitcoin acquisitions have outpaced ETF net inflows for the third consecutive quarter². At CleanSpark, we’ve been strategically positioned for this moment from the beginning. Rather than acquiring bitcoin on the open market, we invested in geographically diverse data center infrastructure backed by low-cost energy, enabling us to produce bitcoin at costs well below market price. Having achieved escape velocity, we are now focused on continuous optimization, responsible growth, increasing operating leverage, and delivering sustained value to our shareholders.”
