Closes on Second Texas Campus, Adding 300 MW of ERCOT-Approved Capacity

LAS VEGAS, March 5, 2026 /PRNewswire/ -- CleanSpark, Inc. (NASDAQ:CLSK) ("CleanSpark" or the "Company"), today released its unaudited Bitcoin mining and operations update for the month ended February 28, 2026.

"In February, we meaningfully expanded our hyperscale-ready infrastructure platform with the closing of our second Texas campus, adding 300 megawatts of ERCOT-approved capacity to our contracted portfolio," said Matt Schultz, Chief Executive Officer and Chairman of CleanSpark. "This transaction strengthens our position as a scaled owner-operator of power-dense digital infrastructure in one of the most attractive power markets in North America. We are advancing our AI and high-performance compute initiatives while maintaining our focus on world-class operational excellence in bitcoin mining."

"We run our balance sheet the same way we run our operations: with conviction. Over the past 18 months, we have repurchased 20% of our own shares because we believe in what we are building," Schultz continued. "We have a flexible treasury strategy, optimized by DAM, generating real cash flow. We allocate deliberately, growing the portfolio and evolving our offering simultaneously, not sequentially."

Schultz concluded, "Our strategy remains consistent: generate predictable cash flow from disciplined mining operations today, monetize hyperscale-ready power and compute infrastructure through tenant-driven growth, and actively manage the balance sheet to preserve flexibility and amplify returns across cycles."
