Forward-Looking Statements

This press release includes certain statements that may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are forward-looking statements for purposes of federal and state securities laws. These forward-looking statements involve uncertainties that could significantly affect Greenidge’s financial or operating results. These forward-looking statements may be identified by terms such as “anticipate,” “believe,” “continue,” “foresee,” “expect,” “intend,” “plan,” “may,” “will,” “would,” “could,” and “should,” and the negative of these terms or other similar expressions. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Forward-looking statements in this press release include, among other things, statements regarding the business plan, business strategy and operations of Greenidge in the future. In addition, all statements that address operating performance and future performance, events or developments that are expected or anticipated to occur in the future are forward looking statements. Forward-looking statements

are subject to a number of risks, uncertainties and assumptions. Matters and factors that could cause actual results to differ materially from those expressed or implied in such forward-looking statements include but are not limited to the matters and factors described in Part I, Item 1A. “Risk Factors” of Greenidge’s Annual Report on Form 10-K for the year ended December 31, 2023, as may be amended from time to time, our subsequently filed Quarterly Reports on Form 10-Q, as well as statements about or relating to or otherwise affected by the completion of management’s final review of the financial results and Greenidge’s other closing procedures. Consequently, all of the forward-looking statements made in this press release are qualified by the information contained under this caption. No assurance can be given that these are all of the factors that could cause actual results to vary materially from the forward-looking statements in this press release. You should not put undue reliance on forward-looking statements. No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, the actual results, performance, or achievements of Greenidge could differ materially from the results expressed in, or implied by, any forward-looking statements. All forward-looking statements speak only as of the date of this press release and Greenidge does not assume any duty to update or revise any forward-looking statements included in this press release, whether as a result of new information, the occurrence of future events, uncertainties or otherwise, after the date of this press release.

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.

That’s similar to what Argentina, the Netherlands and Sweden each use in a year, and is about 0.5 percent of the world's current electricity use.” “According to estimates from the federal Energy Information Administration, U.S. miners of Bitcoin used 70 terawatthours to power their datacenters last year. That's merely 10% of the electricity that A.I. might be drawing in 2030.” “The nation’s 2,700 data centers sapped more than 4 percent of the country’s total electricity in 2022, according to the International Energy Agency. Its projections show that by 2026, they will consume 6 percent. Industry forecasts show the centers eating up a larger share of U.S. electricity in the years that follow…” Proven operators with in-house engineering and electrical capabilities having successfully designed, built and operated over 4 EH/s of bitcoin mining data center operations and over 160 MW of power infrastructure at multiple locations Blueprint to execute on buildouts with new partners for data center capabilities; partnership already inked with Infinite Reality Greenidge has strong relationship with its controlling shareholder who has access to potentially actionable sites Greenidge is the Solution (1) (2) (3) 1.
