CleanSpark (CLSK) Reports May 2025 Bitcoin Mining Update

CleanSpark, Inc. (Nasdaq: CLSK), America's Bitcoin Miner® (the "Company"), today released its unaudited Bitcoin mining and operations update for the month ended May 31, 2025.

"May was a strong execution month for CleanSpark as we continued to advance toward key growth targets," said Zach Bradford, CEO and President. "We increased our month-end hashrate to 45.6 EH/s, up 7.5% sequentially, while improving average fleet efficiency. We expanded our Bitcoin treasury to over 12,500 BTC, all from mining operations and without any equity issued to finance the business since November 2024, underscoring our commitment to shareholder value and disciplined capital management."

"We also secured an additional 72 megawatts of contracted power, bringing our total to 987 megawatts, which strengthens our infrastructure pipeline to support continued disciplined, scalable growth," Bradford added. "This level of operational performance, paired with consistent strategic investment continues to differentiate CleanSpark as the only remaining pure-play, vertically integrated Bitcoin miner in the public markets."

The company also highlighted its presence at Bitcoin 2025 in Las Vegas, where CleanSpark leadership joined discussions on strategic trends in mining, energy and digital asset management.

"Our participation at Bitcoin 2025 further reinforced CleanSpark's leadership role in the space," said Bradford. "Treasury management was a key discussion point, and I was proud to highlight that we are now the sixth-largest public Bitcoin holder, all mined directly through our own operations. It's a powerful validation of our infrastructure-first strategy."

June Outlook: CleanSpark on Track to Reach 50 EH/s with Full Operational Control

"As we enter June, we're positioned to become the first public Bitcoin miner to achieve 50 EH/s entirely through self-operated infrastructure," Bradford noted. "This milestone reflects the strength of our vertically integrated model, allowing us to scale efficiently, retain operational control, and protect margins. Importantly, reaching 50 EH/s is not our endpoint. We intend to continue building, and with much infrastructure already in place, we are well-positioned to achieve over 60 EH/s. We believe this execution-focused strategy will continue to drive long-term value for shareholders."
