CleanSpark, Inc. (Nasdaq: CLSK) announced a 20-year triple-net lease agreement with an undisclosed global technology company for its data center campus in Sandersville, Georgia, according to a company press release dated July 14, 2026.

The lease is expected to generate approximately $6.6 billion in contracted revenue over the initial term, with up to $11.6 billion if two five-year extension options are exercised. The agreement covers 175 megawatts of critical IT load, with deliveries expected to begin in the fourth quarter of 2027.

CleanSpark described the tenant as a high-investment-grade global technology company but did not disclose its identity. The company said the lease carries an expected cumulative net operating income contribution margin of nearly 100%, or an average annual NOI contribution of approximately $330 million. Estimated landlord project costs are $10 million to $12 million per megawatt of critical IT load.

In connection with the lease, the tenant also executed a letter of intent and exclusivity arrangement covering CleanSpark's entire Texas portfolio, which spans 718 acres with up to 885 megawatts of secured and planned power capacity. That portfolio includes sites in Sealy and Brazoria, Texas.

"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," said Matt Schultz, CleanSpark CEO and chairman.

Morgan Stanley & Co. LLC served as financial advisor to CleanSpark, and Davis Polk & Wardwell LLP acted as legal counsel.
