CleanSpark Releases July 2025 Bitcoin Mining Update

Produced 671 bitcoin and surpassed 1 GW in contracted power

LAS VEGAS, Aug. 5, 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 July 31, 2025.

"July was a strong month for both Bitcoin and CleanSpark," said Zach Bradford, President and CEO. "With Bitcoin reaching new all-time highs above $120,000, our disciplined accumulation strategy was validated as our treasury grew to over 12,700 self-mined bitcoin. Importantly, we continued to self-fund our operations through strategic Bitcoin sales, enabling ongoing accumulation while avoiding any use of equity financing or shareholder dilution. At the same time, CleanSpark's total contracted power surpassed 1 gigawatt, a significant achievement that reflects the scalability of our infrastructure-first approach."

"While a heatwave in the Southeast led to periodic load reductions in response to heightened grid demand across several regions, our flexible power agreements and geographically diversified footprint proved their strategic value," Bradford continued. "Our ability to support utility partners during periods of peak demand highlights the increasingly important role Bitcoin mining can play in grid stability. This mutually beneficial relationship has enabled us to secure over 1 gigawatt of power across four states, and we are well positioned for further expansion. As we continue to grow, our focus remains on delivering durable shareholder value through scale, operational efficiency, and long-term profitability."

CleanSpark will discuss its fiscal third quarter 2025 financial results via a live webcast beginning at 4:30 p.m. EST / 1:30 p.m. PST on Thursday, August 7, 2025.
