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, gains or losses from the sales of assets and stock-based compensation. 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.
