Company Exceeds Expectations with 50 EH/s Hashrate Achievement
Self-Mined Bitcoin Holdings Reach 12,608 BTC
LAS VEGAS, July 7, 2025 /PRNewswire/ — CleanSpark, Inc. (Nasdaq: CLSK), a leading Bitcoin mining firm in the United States, today announced its unaudited performance figures for Bitcoin mining and operational activities as of June 30, 2025.
According to CEO Zach Bradford, “June 2025 was a landmark period for CleanSpark. We successfully attained our goal of 50 EH/s in operational hashrate by the middle of the year. We are the first Bitcoin mining organization to accomplish this exclusively through our own infrastructure. This represents a 9.6% growth from the previous month and improved our energy efficiency to 16.15 J/Th. I extend my sincere appreciation to our dedicated team, particularly COO Scott Garrison and CTO Taylor Monnig, for their strong leadership. Thanks to their guidance, our operations and tech teams added over 10 EH/s of capacity across four states to meet our objective. With our current talent, facilities, and energy agreements, CleanSpark is in an excellent position for continued growth.”
“We have secured contracts for an additional 179 megawatts of power, sufficient to support over 10 EH/s of further hashrate. We are actively working to expand our infrastructure to utilize this capacity. These advancements will bolster efficient and sustainable expansion. This progress stems from careful planning and execution across energy sourcing, engineering, and site construction. And this is just the beginning. We have a significant pipeline of additional power sources under development and review, setting a clear course for CleanSpark’s next phase of long-term, scalable growth.”
As a top-tier, vertically integrated Bitcoin miner, CleanSpark continues to be a leader in operational excellence and strategic management. The company’s Bitcoin holdings have reached 12,608 BTC, placing them seventh among publicly traded firms globally1. All of these holdings were generated through self-mining activities.
Gary A. Vecchiarelli, CFO, stated, “CleanSpark has launched its Digital Asset Management initiatives and is currently in the ‘crawl phase.’ Our initial strategies are live, and we are seeing promising results from our actively managed spot sales program and derivative overlay. In June, we achieved an average selling price of $105,860 per Bitcoin after fees, $446 higher than the VWAP for the same period, not including premiums from derivative transactions. While these strategies are still developing, I’m proud of the high-level performance our treasury team has already shown.”
Bradford added, “This is a crucial time for Bitcoin. Businesses worldwide are recognizing the value of incorporating Bitcoin into their balance sheets. Corporate Bitcoin acquisitions have surpassed ETF inflows for the third straight quarter2. At CleanSpark, we have been strategically prepared for this from the beginning. Instead of buying Bitcoin on the open market, we have invested in geographically diverse data centers powered by low-cost energy, enabling us to produce Bitcoin at prices well below market value. Having achieved rapid growth, we’re now focusing on ongoing improvements, responsible expansion, maximizing operational efficiency, and delivering consistent value to our shareholders.”
