Greenidge currently has 119MW of active self-mining, hosting and power generation across sites in New York, Mississippi and North Dakota. With planned mining capacity of 2.5MW expected to be added in Q2 2025 and 25MW by Q4 2025, Greenidge expects to end the year with a total mining capacity of 146.5MW. The Company's active datacenter operations consist of approximately 2.9 EH/s of datacenter hosting and cryptocurrency mining, of which 1.8 E/Hs, is associated with datacenter hosting and 1.1 E/Hs is associated with our cryptocurrency mining.

Greenidge ended the fourth quarter with $8.6 million of cash and $68.5 million in aggregate principal amount of debt.

Greenidge CEO Jordan Kovler commented: "Throughout 2024, we took significant steps to further right-size the business and stabilize our operations, reducing SG&A expenses by almost $9 million. We also implemented important new growth strategies, including the acquisition and successful buildouts of sites in Mississippi and North Dakota that represented 15MW of additional mining capacity."

Kovler added: "In 2025, we will continue to execute on our long-term growth plan to identify and monetize value-accretive properties for either bitcoin mining or high-performance computing. Among the strategic opportunities we are actively exploring is the potential acquisition of a property with over 200MW of low-cost power assets. However, successfully executing on a transaction of this scale will require us to strengthen our capital structure to maximize its potential and drive long-term value for stockholders.

After having successfully reduced the aggregate principal amount of our debt by nearly 7.5% through privately negotiated debt-for-equity exchanges, we recognize the need to further strengthen our balance sheet. To that end, we believe that the best opportunity to position the Company for long-term growth and maximize future returns for all Greenidge stakeholders will require the conversion of a substantial amount of our outstanding notes into equity at a meaningful discount to par value."

Use of Non-GAAP Information

To provide investors and others with additional information regarding Greenidge's financial results, Greenidge has disclosed in this press release the non-GAAP operating performance measures of Adjusted EBITDA. Adjusted EBITDA is defined as earnings before interest, taxes and depreciation and amortization, which is then adjusted for stock-based compensation and other special items determined by management, including, but not limited to, business expansion costs, impairments of long-lived assets, gains or losses from the sales of long-lived assets, remeasurement of environmental liabilities, restructuring and loss on extinguishment of debt. These non-GAAP financial measures are a supplement to and not a substitute for or superior to, Greenidge's results presented in accordance with U.S. GAAP. The non-GAAP financial measures presented by Greenidge may be different from non-GAAP financial measures presented by other companies. Specifically, Greenidge believes the non-GAAP information provides useful measures to investors regarding Greenidge's financial performance by excluding certain costs and expenses that Greenidge believes are not indicative of its core operating results. The presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for results or guidance prepared and presented in accordance with U.S. GAAP.

Because of these limitations, EBITDA and Adjusted EBITDA should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. Greenidge compensates for these limitations by relying primarily on its GAAP results and using EBITDA and Adjusted EBITDA on a supplemental basis.
