Investing.com -- CleanSpark Inc. shares were trading about 15% higher in pre-market on Tuesday after the data center developer announced a 20-year infrastructure lease agreement at its Sandersville, Georgia campus.

The lease with an unnamed global technology company is expected to generate around $6.6 billion in contracted revenue over the initial term. The agreement includes two five-year extension options that could bring the total contract value to $11.6 billion.

The tenant will deploy production-grade infrastructure at Sandersville for various computing workloads. The company has also signed 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.

Matt Schultz, CleanSpark CEO and chairman, said the lease marks a transformation for the company as it moves into a diversified digital infrastructure platform and begins monetizing its power portfolio at institutional scale.

The lease is structured as a triple net agreement with annual escalators. CleanSpark expects an average annual net operating income contribution of about $330 million, with estimated landlord project costs of $10 million to $12 million per megawatt of critical IT load.

The Texas portfolio under exclusivity includes 271 acres with nearly 300 megawatts at the Sealy campus and 447 acres at the Brazoria campus. The Brazoria site has transmission-level infrastructure supporting an initial 300 megawatt demand load with potential expansion to 600 megawatts.
