CleanSpark Releases April 2025 Bitcoin Mining Update

Exceeds 12,100 bitcoin held in treasury

Evolves capital strategy; funding monthly operating expenses through production

LAS VEGAS, May 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 April 30, 2025.

"A little over a year after the most recent halving, our operational performance across varying market conditions has validated the strength of our scale, strategic focus, and disciplined execution," said CleanSpark CEO and President Zach Bradford. "April brought a modest increase in network difficulty and some temporary hashrate curtailment due to ongoing construction, both expected and manageable factors. We remain committed to our core fundamentals and are on track to reach 50 EH/s by mid-year. Our ongoing construction in Tennessee and Wyoming are nearing completion and will represent a significant step forward in expanding our operating capacity and long-term value creation."

"In April, we advanced our capital strategy by securing a $200 million revolving credit facility with Coinbase, reflecting our disciplined approach to balance sheet optimization," said CleanSpark CFO Gary Vecchiarelli. "We also monetized a portion of our bitcoin production to fully self-fund operations and manage liquidity proactively. Thanks to our Digital Asset Management group, we executed sales at an average bitcoin price exceeding $90,000, demonstrating disciplined market execution and institutional-grade capabilities. As we'll discuss further on our upcoming earnings call, we believe our institutional treasury capabilities will further enhance CleanSpark's leadership in operational excellence and capital stewardship."
