DRESDEN, N.Y. – October 4, 2021 – Greenidge Generation Holdings Inc. (NASDAQ: GREE) (“Greenidge”) today announced selected preliminary financial and operating results for the three months ended September 30, 2021.

Non-GAAP Financial Measures

From time to time Greenidge utilizes certain financial measures that are not prepared or calculated in accordance with GAAP to assess financial performance and profitability.

GREE Earnings Pre-Announcement Release

“EBITDA” is defined as earnings before interest, taxes, and depreciation and amortization. “Adjusted EBITDA” is defined as EBITDA adjusted for stock-based compensation and other special items determined by management, including, but not limited to, acquisition related expenses, business development, fair value adjustments for certain financial liabilities (including asset retirement obligations), costs associated with debt and equity transactions, and impairment charges as they are not indicative of business operations. Adjusted EBITDA is intended as a supplemental measure of Greenidge’s performance that is not presented in accordance with GAAP. Greenidge believes that the use of EBITDA and Adjusted EBITDA provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing its financial measures with those of comparable companies, which may present similar non-GAAP financial measures to investors. However, you should be aware that when evaluating EBITDA and Adjusted EBITDA, Greenidge may incur future expenses similar to those excluded when calculating these measures. In addition, Greenidge’s presentation of these measures should not be construed as an inference that its future results will be unaffected by unusual or non-recurring items. Greenidge’s computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies, because all companies may not calculate Adjusted EBITDA in the same fashion.

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. You should review the reconciliation of net loss to EBITDA and Adjusted EBITDA below and not rely on any single financial measure to evaluate Greenidge’s business.

The following table reconciles the expected range of net loss to the expected ranges of EBITDA and Adjusted EBITDA for the three months ended September 30, 2021 (in millions):

($ in millions)	Three Months Ended September 30, 2021
