CleanSpark Secures Twenty-Year Lease with High-Investment Grade Global Technology Company for Data Center in Sandersville, Georgia

Tenant has executed a letter of intent and exclusivity arrangement covering CleanSpark's entire Texas portfolio of 885 MW

LAS VEGAS, July 14, 2026 /PRNewswire/ -- CleanSpark, Inc. (Nasdaq: CLSK) ("CleanSpark" or the "Company"), a market leading data center developer, today announced it has entered into a 20-year infrastructure lease agreement, with two five-year extension options, directly with a high-investment grade, leading global technology company at its Sandersville, Georgia, campus. The lease is expected to generate approximately $6.6 billion of contracted revenue over the initial term.

Under the agreement, the global technology company will deploy production-grade infrastructure at Sandersville, dedicated to a range of computing workloads. In connection with the transaction, the tenant has also executed a letter of intent and exclusivity arrangement covering CleanSpark's entire Texas portfolio of 718 acres with up to 885 MW of secured and planned power capacity, positioning Sandersville as the first chapter of a substantially larger relationship.

"This lease is a transformational moment for CleanSpark as we complete our evolution into a diversified digital infrastructure platform and begin monetizing our power portfolio at institutional scale," said Matt Schultz, CleanSpark CEO and chairman. "A 20-year commitment from a high-investment-grade global technology company with a market-leading commercial profile and exclusivity across our nearly 900 MW of additional capacity in Texas is a tremendous validation of our land-and-power strategy. We have long believed in the second-mover advantage in this sector: grow our portfolio as the market matures, then execute with excellent terms and velocity. Today's announcement validates our thesis."

A Foundation Built at Sandersville

The Sandersville campus was selected for its access to reliable, low-cost power, available capacity for high-density compute, and its ability to support rapid, phased deployment of advanced data center infrastructure. Since the 2022 launch of its Sandersville operations, CleanSpark has established a sustained presence in the local community, investing in energy infrastructure, site development, and long-term operations that support economic activity throughout the region.

"CleanSpark has been a pillar of the Sandersville community for many years, providing job market stability, tax revenue, and broad support for what makes our part of the world special," said Mayor Jimmy Andrews. "We are excited to see CleanSpark embark on this new chapter and stand shoulder to shoulder with them to support this incredible infrastructure project."

While the tenant remains confidential, they are a global technology company among the high-investment-grade cohort, facilitating CleanSpark's financing options and the multi-decade term of the lease.
