Third Quarter 2024 Highlights:

During the third quarter of 2024, Greenidge's cryptocurrency mining and datacenter hosting operations produced approximately 167 bitcoin, of which 54 bitcoin were produced by proprietary cryptocurrency mining and 113 bitcoin were produced for datacenter hosting clients. The bitcoin production update by month is as follows:

• September 2024: Greenidge produced approximately 54 bitcoin in September, of which 17 bitcoin were produced by Greenidge-owned miners and 36 were produced through our datacenter hosting. Greenidge's hash rate in September was approximately 2.5 EH/s, with 0.8 EH/s from Greenidge-owned miners and 1.7 EH/s from our datacenter hosting.

• August 2024: As previously announced, Greenidge produced approximately 55 bitcoin in August, of which 17 bitcoin were produced by Greenidge-owned miners and 38 were produced through our datacenter hosting. Greenidge's hash rate in August was approximately 2.50 EH/s, with 0.8 EH/s from Greenidge-owned miners and 1.7 EH/s from our datacenter hosting.

• July 2024: As previously announced, Greenidge produced approximately 58 bitcoin in July, of which 19 bitcoin were produced by Greenidge-owned miners and 39 bitcoin were produced through our datacenter hosting. Greenidge's hash rate in July was approximately 2.37 EH/s, with 0.77 EH/s from Greenidge-owned miners and 1.60 EH/s from our datacenter hosting.

As of September 30, 2024, Greenidge operates a fleet of approximately 29,000 total bitcoin miners for both cryptocurrency mining and datacenter hosting with approximately 3.1 EH/s of total hashrate capacity. Greenidge's operational miner fleet consists of approximately 18,000 miners or 1.8 EH/s of hashrate for datacenter hosting clients and approximately 11,000 miners or 1.3 EH/s of hashrate for its own proprietary cryptocurrency mining.

Greenidge ended the quarter with approximately $11.3 million of cash and digital assets, including 60 bitcoin and approximately $69.5 million of debt.

SG&A Update:

The Company's efforts to reduce SG&A expenses continue to yield results, as total SG&A expenses for the first three quarters of 2024 are $13.6 million versus $22.7 million in the first three quarters of 2023, a savings of $9.1 million, which exceeds the Company's stated $7 million goal at the beginning of the year.

Fleet Upgrade Update:

Over the second half of 2024 and throughout 2025, Greenidge anticipates continuing to gradually upgrade its miner fleet with newer generation miners, in addition to securing additional sites for future development and potentially monetizing certain assets. Through miner purchases made in 2024 to date, which include over 1,000 miners expected to be received and deployed by the end of 2024, Greenidge's expected miner fleet efficiency will improve to approximately 26.5 J/TH from the previously reported efficiency of 28.7 J/TH as of June 30, 2024.

The preliminary financial information presented in this press release is based on Greenidge's current expectations and may be adjusted as a result of, among other things, completion of customary quarterly financial review and audit procedures.

Litigation Update:

The Company currently expects that a hearing will be held in late October in the New York State Supreme Court, Yates County, on its previously disclosed request for a temporary restraining order and preliminary injunction allowing its Dresden, NY facility to continue operations during the pendency of the Company's Article 78 challenge of the New York Department of Environmental Conservation's denial of its Title V Air Permit renewal application.

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.
