Today $CLSK reported fiscal year third quarter 2025 results (ended 6/30/25). *Quarterly revenue: $198.6 million (up 90.8% from same prior fiscal quarter) *Quarterly bitcoin production: 2,012 *Quarterly average revenue per coin: $98,753 Full press release here: https://lnkd.in/gkrW2kSc "This was the most successful quarter in CleanSpark's history, and it reflects the strength of our strategy, the discipline of our execution, and the tireless commitment of our team," said Zachary Bradford, CEO of CleanSpark. "We reached 50 EH/s of operational hashrate in June, becoming the first public company to do so exclusively with American infrastructure, while achieving record basic EPS of $0.90 and nearly $200 million in revenue. We also grew our bitcoin treasury to over $1 billion in value, all without raising capital through equity offerings since November 2024. These results show we're not just scaling, we're doing so efficiently, responsibly, and profitably." Bradford continued "Having achieved 5.8% of global hashrate under management and over one gigawatt of power contracted, CleanSpark is proving that our vertically integrated model is built not just for growth, but for leadership. As the Bitcoin network evolves, our focus remains on expanding market share in bitcoin production, leveraging our unmatched operational playbook, and executing with the urgency and excellence that have brought us to this point. We believe the future of Bitcoin will be defined by those who build with purpose, and CleanSpark is setting the standard." "Fiscal Q3 was a pivotal quarter for CleanSpark, as we fully funded operational expenses through monthly bitcoin production while simultaneously expanding our bitcoin treasury," said Gary A. Vecchiarelli, CPA Chief Financial Officer of CleanSpark. "We also launched our Digital Asset Management team' derivatives strategy, which began producing promising early returns and validating our approach. As we look ahead, we remain committed to drive accretive growth through high-efficiency operations and a resilient, strategically positioned balance sheet."
