CleanSpark Reaches 50 EH/s Milestone; Escape Velocity in Action

First publicly traded miner to reach this scale with fully self-operated infrastructure 

LAS VEGAS, June 24, 2025 /PRNewswire/ -- CleanSpark, Inc. (Nasdaq: CLSK), America's Bitcoin Miner®, today announced it has achieved its mid-year target of 50 exahashes per second (EH/s) of operational hashrate, a measure of computing power dedicated to mining Bitcoin. 

"Reaching 50 EH/s is a major milestone. It reflects years of focused strategy, disciplined execution, and a relentless commitment to doing things the right way," said Zach Bradford, CleanSpark's CEO and President. "This growth didn't happen by chance. It's the result of building and operating our own infrastructure, often from the ground up, which has given us the control, resilience, and scalability needed to lead in this industry."

CleanSpark's infrastructure portfolio spans more than 30 locations across Georgia, Mississippi, Tennessee, and Wyoming, with vertically integrated control over energy procurement, development, and operations. The Company's approach emphasizes long-term sustainability, high uptime, and low marginal cost per bitcoin.

"We've never pursued growth for its own sake," Bradford continued. "Every new megawatt and every additional exahash has been deliberately designed to create long-term shareholder value and advance our vision of becoming the global leader in Bitcoin mining, built right here in rural America."

"As we look to the future, CleanSpark has laid the foundation to achieve 60 EH/s and beyond. This expansion capacity aligns with the Company's broader strategy to grow with capital efficiency only possible for an operator that has achieved escape velocity."

At the same time, CleanSpark's Digital Asset Management (DAM) division continues to mature, actively managing the Company's self-mined bitcoin holdings of more than 12,500, as a strategic treasury asset, to support growth. These activities began generating results in May through active monetization and yield initiatives, forming a key element of CleanSpark's non-dilutive growth approach.

"We're mining Bitcoin efficiently, holding it responsibly, and putting it to work in ways that drive shareholder value," Bradford concluded. "With unmatched scale, non-dilutive growth in motion, and compelling opportunities on the horizon, I've never been more confident in CleanSpark's future or prouder of the team building it."
