Greenidge Generation Holdings Inc. (Nasdaq: GREE) (together with its controlled affiliates, “Greenidge” or the “Company”), a vertically integrated cryptocurrency data center and power generation company, today announced the closing of the sale of its 152-acre property located in Spartanburg, South Carolina to an affiliate of The Lightstone Group and LightHouse Data Centers (the “Transaction”). The consideration for the Transaction consists of $18.0 million in cash at closing (subject to upward adjustment) and the right to receive up to $18.0 million in additional earnout payments. The earnout payments are payable at $180,000 per megawatt (MW) of power capacity made available to the property before 2031, to the extent such capacity exceeds the 60 MW Greenidge previously secured for delivery by September 2026.

Jordan Kovler, Chief Executive Officer of Greenidge, commented: “The sale of our South Carolina property validates our disciplined playbook of identifying overlooked, low-cost power assets, maximizing their capacity, and monetizing them at the optimal time. This is the same playbook driving progress on our Mississippi expansion site, where 40 megawatts are expected to be available by March 2027. By delivering substantial, immediate liquidity while retaining meaningful upside, we are diversifying our revenue streams, optimizing every megawatt under our control, and creating lasting value for shareholders.”

Kovler continued, “This transaction and transformative year of balance sheet restructuring position the Company to enter 2026 with a stronger balance sheet and a clear focus on driving sustainable free cash flow from our flagship Dresden facility. In parallel, we are evaluating options for the remaining holders of our 2026 notes to participate in our next chapter of growth, which may include offering the opportunity to exchange 2026 notes for higher-yielding 2030 notes in one or more transactions that we believe would qualify as a tax-free recapitalization.”

Over the past year, Greenidge has reduced the principal on its 2026 senior indebtedness to approximately $37.8 million through a series of public and privately negotiated tender and exchange offers. Through divesting non-core assets, Greenidge has raised approximately $22.1 million in cash, inclusive of approximately $17.9 million in net proceeds from this Transaction. With existing cash and bitcoin holdings of approximately $9.8 million as of November 30, 2025, Greenidge’s pro forma Net Debt has improved to approximately $12.4 million, from $52.9 million at the beginning of the year.

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 the Company’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.

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 under the heading “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as may be amended from time to time, its subsequently filed Quarterly Reports on Form 10-Q and its other filings with the Securities and Exchange Commission (the “SEC”). Consequently, all of the forward-looking statements made in this press release are qualified by the information contained under this caption.

You should not put undue reliance on forward-looking statements.

Use of Non-GAAP Information

To provide investors and others with additional information regarding Greenidge’s financial performance, Greenidge has disclosed in this press release the non-GAAP financial measures of Total Debt and Net Debt. The most directly comparable GAAP financial measure to Total Debt and Net Debt is total long-term debt (including the current portion), which is reported at amortized cost on the Company’s consolidated balance sheet in accordance with U.S. GAAP (ASC 470-60). Total Debt differs from the GAAP measure of total long-term debt as it represents the aggregate outstanding principal indebtedness under the Company’s 8.50% Senior Notes due 2026 and 10.00% Senior Notes due 2030, excluding adjustments for unamortized discounts, premiums, and issuance costs that are netted against the principal under GAAP to arrive at the carrying value. Net Debt is defined as Total Debt less cash and cash equivalents (including restricted cash) and digital assets. The Company presents Total Debt and Net Debt on both an actual basis as of November 30, 2025 (preliminary) and a pro forma basis (after giving effect to the sale of the Company’s South Carolina property). The Company believes the pro forma financial information may be useful to investors in understanding the potential effect of the sale of the South Carolina property on the Company’s capital structure, its future borrowing capacity, and its ability to service its debt. Greenidge’s presentation of Total Debt and Net Debt may be different from similar non-GAAP financial measures presented by other companies given the inclusion of the fair market value of digital assets in the calculation of Net Debt. Greenidge’s presentation of Total Debt and Net Debt 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.

The pro forma financial information above is unaudited, presented for illustrative purposes only and not necessarily indicative of the Company’s future results or financial position. The pro forma financial information is based on preliminary estimates and assumptions that management believes to be reasonable, but actual results may differ materially. The pro forma financial information should be read together with the Company’s historical financial statements and the notes thereto contained in the Company’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and its other filings with the SEC.
