Greenidge Generation Holdings Inc.

We are a developer and operator of datacenters and powered assets designed to support energy-intensive computing workloads. We currently build, maintain, and operate datacenters focused on bitcoin mining, along with related power and electric infrastructure. We generate revenue from datacenter hosting, cryptocurrency self-mining, and power and capacity sales. We are increasingly focused on leveraging our power generation assets, grid interconnection rights, and datacenter development expertise to support artificial intelligence ("AI") and high-performance computing ("HPC") workloads. We own and operate a vertically integrated cryptocurrency datacenter and power generation facility in Torrey, New York (the "New York Facility"), which includes a natural gas power generation plant with approximately 106 megawatt ("MW") of nameplate capacity. We also own a 34-acre greenfield site in Columbus, Mississippi, which is expected to provide access to 40 MW of datacenter capacity by the first quarter of 2027. Additionally, we have 7.5 MW of datacenter capacity in North Dakota (the "North Dakota Facility") through a five-year lease, which provides energy access for our cryptocurrency mining operations. On December 11, 2025, we completed the sale of our 152-acre property in Spartanburg, South Carolina (the "South Carolina Land") and assigned our rights to 60 MW of electrical service, expected by September 2026, to an affiliate of The Lightstone Group and LightHouse Data Centers. The sale consideration included $18.0 million in cash at closing and the right to receive up to $18.0 million in additional future contingent payments. For the year ended December 31, 2025, we recognized a gain on this sale of $10.5 million.
