Greenidge Generation Holdings Inc. (NASDAQ: GREE) (“Greenidge”), a vertically integrated cryptocurrency datacenter and power generation company, today announced favorable preliminary financial and operating results for the fourth quarter of 2023.

Preliminary Fourth Quarter 2023 Financial Results¹:

• Revenue of approximately $19.7 million;

• Cryptocurrency datacenter self-mining revenue of $7.3 million;
• Cryptocurrency datacenter hosting revenue of $10.7 million; and
• Power and capacity revenue of $1.7 million;

Fourth Quarter 2023 Highlights:

Our cryptocurrency datacenter operations produced approximately 710 bitcoin during the fourth quarter of 2023, of which 506 bitcoin were produced for colocation and 203 bitcoin were produced for self-mining. The average closing price of Bitcoin during the fourth quarter of 2023 was $36,276.79.

As of December 31, 2023, Greenidge datacenter operations consisted of approximately 29,700 miners with approximately 3.1 EH/s of combined capacity for both datacenter hosting and cryptocurrency mining, of which 19,000 miners, or 1.9 EH/s, is associated with datacenter hosting and 10,700 miners, or 1.2 EH/s, is associated with Greenidge's cryptocurrency mining.

Greenidge ended the quarter with approximately $13.6 million of cash and approximately $68.7 million of debt. In aggregate, Greenidge reduced its debt by $85.3 million in 2023, representing over 54% of its total debt.

Greenidge CEO Jordan Kovler commented: “We had a strong year on many fronts, including significantly reducing our debt load and making the necessary changes to alter the trajectory of the business, culminating in our first profitable quarter in two years. We continue to work diligently on paths to increasing profitable revenue and reducing debt. While there is more to come, I want to thank our team for the hard work that led to us delivering at least $0.18 in earnings per share and $1.4 million in net income in the fourth quarter, with a lower average Bitcoin price than we see today. We remain relentlessly focused on expanding our reach into low-cost power centers, our growing EPCM business, AI infrastructure/data centers and innovative approaches to embrace increased interest in bitcoin. I am confident that Greenidge’s approach and resources differentiate us from our competitors and positions us well for future growth.”

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 annual audit procedures. Management plans to discuss Greenidge’s complete fourth quarter and full-year 2023 financial results after the market closes on March 27, 2024.

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.
