ORGANIZATION AND DESCRIPTION OF BUSINESS	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND DESCRIPTION OF BUSINESS	ORGANIZATION AND DESCRIPTION OF BUSINESS Greenidge Generation Holdings Inc. ("Greenidge") and its subsidiaries (collectively, the "Company") own and operate a vertically integrated cryptocurrency datacenter and power generation company. The Company owns and operates a facility in the Town of Torrey, New York (the "New York Facility") and owned and operated a facility in Spartanburg, South Carolina (the "South Carolina Facility"). The Company generates revenue in U.S. dollars by providing hosting, power and technical support services to third-party owned bitcoin mining equipment and generates revenue in the form of bitcoin by earning bitcoin as rewards and transaction fees for supporting the global bitcoin network with application-specific integrated circuit computers ("ASICs" or "miners") owned by the Company, which may be operated at the Company's sites or at third-party hosting sites through short-term hosting agreements. The earned bitcoin are then exchanged for U.S. dollars. The Company also owns and operates a 106 megawatt ("MW") power facility that is connected to the New York Independent System Operator ("NYISO") power grid. In addition to the electricity used "behind the meter" by the New York datacenter, the Company sells electricity to the NYISO at all times when its power plant is running and increases or decreases the amount of electricity sold based on prevailing prices in the wholesale electricity market and demand for electricity. On November 9, 2023, the Company closed the sale of the South Carolina Facility as part of a deleveraging transaction. See Note 14, Subsequent Events , for further details. Effective May 16, 2023, the Company effected a 1-for-10 reverse stock split of its outstanding shares of common stock. Unless specifically provided otherwise herein, all share and per share amounts of our common stock presented have been retroactively adjusted to reflect the reverse stock split. See Note 9, " Stockholder's Equity ", for further details.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Sep. 30, 2023
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Presentation of Condensed Consolidated Financial Statements In the opinion of Greenidge management, the accompanying condensed consolidated financial statements include all adjustments necessary for a fair presentation of the results for the interim periods presented and such adjustments are of a normal recurring nature. The results for the unaudited interim condensed consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2023 or for any future interim period. The unaudited interim condensed consolidated financial statements do not include all of the information and notes required by United States Generally Accepted Accounting Principles for complete financial statements. The Company has reflected the operations of its Support.com business as discontinued operations for all periods presented. See Note 3, “ Assets Held for Sale and Discontinued Operations ” for further information. Unless otherwise noted, amounts and disclosures throughout these notes to the Company's condensed consolidated financial statements relate solely to continuing operations and exclude all discontinued operations. The accompanying condensed consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements of the Company in its 2022 Annual Report on Form 10-K. Going Concern In accordance with the Financial Accounting Standards Board (the "FASB") Accounting Standards Update ("ASU") 2014-15, Presentation of Financial Statements – Going Concern , the Greenidge's management evaluated whether there are conditions or events that pose risk associated with the Company's ability to continue as a going concern within one year after the date these financial statements have been issued. The Company’s condensed consolidated financial statements have been prepared assuming that it will continue as a going concern. When comparing to December 31, 2021, during 2022 the bitcoin price declined as much as 66% and ended the year 64% lower. Natural gas prices were much higher during 2022 compared to 2021, peaking at approximately 160% higher than the December 31, 2021 price, and ending the year approximately 47% higher than the December 31, 2021 price. The volatility in these commodity prices negatively impacted the Company's results in 2022 and, while the market has improved in 2023, the Company continues to address the negative impacts. As a result, management took certain actions during the second half of 2022 and during 2023 to improve the Company's liquidity that are described further below. At September 30, 2023, the Company had $10.7 million of cash, restricted cash and cash equivalents, while having $29.6 million of accounts payable and accrued expenses, an estimated $1.7 million of environmental liability spend in the next 12 months, which are the main drivers of a negative ending working capital deficit. Additionally, the Company has $6.1 million of interest payments due over the next twelve months, exclusive of the debt and principal payments which were settled subsequent to September 30, 2023, as a result of the NYDIG transaction described below. The ability to continue as a going concern is dependent upon the Company generating profitable operations in the future and/or obtaining the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. In an effort to improve liquidity, the Company has completed or is in the process of completing the following transactions: • In September 2022, Greenidge entered into an at-the-market issuance sales agreement, as amended, dated as of September 19, 2022, by and among the Company, B. Riley Securities, Inc. (“B. Riley Securities”) and Northland Securities, Inc., relating to shares of Greenidge’s Class A common stock (the "ATM Agreement"), and since October 1, 2022 through November 10, 2023, have received net proceeds of $14.0 million from sales of Class A common stock under the ATM Agreement, of which $11.7 million of net proceeds was received since January 1, 2023. See Note 9, " Stockholder's Equity ", for further details. • On January 30, 2023, the Company entered into debt restructuring agreements with NYDIG ABL LLC ("NYDIG") and B. Riley Commercial Capital, LLC ("B. Riley Commercial"). The restructuring of the NYDIG debt is expected to improve the Company's liquidity during 2023 as the payments required in 2023 on the remaining principal balance is interest payments of $2.0 million. This reduced debt service is substantially lower than the $62.7 million of principal and interest payments which would have been required in 2023 pursuant to the 2021 and 2022 Master Equipment Finance Agreements, both of which were refinanced in January 2023. See Note 5, " Debt " for further details regarding the debt restructuring agreements. • In conjunction with the restructuring of the debt with NYDIG, the Company also entered into hosting agreements with NYDIG on January 30, 2023 (the “NYDIG Hosting Agreements”), which is expected to improve its liquidity position, as it provided for cost reimbursements for key input costs, while allowing the Company to participate in the upside should bitcoin prices rise. • In August 2023, in connection with a non-binding term sheet that the Company entered into with NYDIG in June to effect a deleveraging transaction, the Company completed an electrical upgrade at its South Carolina facility increasing the capacity to 44 MW. Upon completion of this expansion, on August 10, 2023, the Company and NYDIG amended the NYDIG Hosting Agreements to increase the number of miners being hosted by Greenidge utilizing all of the expansion. The NYDIG Hosting Agreements were amended in furtherance of the broader transaction contemplated by the non-binding term sheet pursuant to which the Company would sell to NYDIG all of the upgraded mining facilities at the South Carolina site and would also subdivide and sell to NYDIG the approximately 22 acres of land on which the facilities are located. This deleveraging transaction with NYDIG closed on November 9, 2023. In exchange for the sale to NYDIG of the upgraded South Carolina mining facilities and the subdivided approximate 22 acres of land, Greenidge received total consideration of approximately $28 million: ◦ The Senior Secured Loan with NYDIG with remaining principal of approximately $17.7 million was extinguished; ◦ The B Riley Commercial Secured Promissory Note with remaining principal of approximately $4.1 million as of September 30, 2023, which NYDIG purchased from B. Riley Commercial on July 20, 2023 at par was extinguished; ◦ A cash payment of approximately $4.5 million, and; ◦ The Company will also receive bonus payments earned of approximately $1.6 million as a result of the completion of the expansion of the upgraded mining facility and the facility's uptime performance, which are payable at the completion of the transition services period, which is anticipated to occur in December 2023. In conjunction with the sale, the Company and NYDIG terminated the South Carolina Hosting Order. As a result, at the time of closing the Company returned NYDIG's security deposit, which are included in other long-term liabilities as of September 30, 2023, resulting in a cash outflow of $2.2 million. Within thirty days of closing, the Company also expects to receive a cash inflow of $3.5 million from the return of its security deposit held by the local utility, which was included in prepaid expenses and other assets as of September 30, 2023. Additionally, the Company paid the remaining accrued interest on the Senior Secured and Secured Promissory Note of $0.9 million. The Company also settled certain third party transaction costs and Greenidge's share of local taxes of $0.5 million. Prior to the closing of the South Carolina Facility sale, the Company had a cash outflow of approximately $0.9 million related to the settlement of accounts payable related to the facility upgrade, which were classified as current liabilities held for sale as of September 30, 2023. Following the completion of the South Carolina Facility sale, the Company continues to own approximately 153 acres of land in South Carolina, and is assessing potential uses of the remaining site, which may include the sale of the property. The NYDIG Hosting Agreements related to the New York Facility were not impacted by this transaction and remain in place. • In addition, the Company sold equipment, coupons and certain environmental credits for total proceeds of $11.7 million from the second quarter of 2022 through the second quarter of 2023 to raise additional funds. • Since entering into the NYDIG Hosting Agreements, the Company has identified opportunities to deploy its company-owned miners. In March 2023, the Company entered into a hosting agreement with Conifex Timber Inc. ("Conifex"), whereby Conifex will provide hosting services to Greenidge utilizing renewable power (the “Conifex Hosting Agreement”). In April 2023, the Company entered into a hosting agreement with Core Scientific, Inc. ("Core") in which Core will host and operate Greenidge-owned bitcoin miners at its facilities (the “Core Hosting Agreement”, and together with the NYDIG Hosting Agreements and the Conifex Hosting Agreement, the “Hosting Agreements”). In addition, the Company installed approximately 1,500 additional company-owned miners at its existing facilities in Dresden, New York. The Company believes that the installation of these miners at Conifex and Core facilities along with those miners at its own facilities will improve the Company's profits and liquidity during the remainder of 2023 and beyond. Despite these improvements to the Company's financial condition, Greenidge management expects that it will require additional capital in order to fund the Company’s expenses and to support the Company’s near-term working capital needs and remaining debt servicing requirements. Management continues to assess different options to improve its liquidity which include, but are not limited to: • issuances of equity, including but not limited to issuances under the Equity Purchase Agreement and/or the ATM Agreement. • a sale of the Company's remaining real estate in South Carolina and/or sale of the remaining miner infrastructure equipment inventory, which was not used in the South Carolina expansion. The Company estimates that its cash resources will be depleted by the end of the first quarter of 2024. The Company's estimate of cash resources available to the Company for the next 12 months is dependent on completion of certain actions, including the completion of the sale of the South Carolina real estate, a sale of remaining equipment inventory, or obtaining additional short-term outside financing; as well as bitcoin prices and blockchain difficulty levels similar to those existing as of the filing of this Quarterly Report on Form 10-Q and energy prices similar to the those experienced in the third quarter of 2023. While bitcoin prices have begun to recover during the first nine months of 2023 from the significant declines experienced in 2022, management cannot predict when or if bitcoin prices will recover to sufficient levels for a sustained period of time, or the volatility of energy costs. While the Company continues to work to implement options to improve liquidity, there can be no assurance that these efforts will be successful and the Company's liquidity could be negatively impacted by factors outside of its control, in particular, significant decreases in the price of bitcoin, regulatory changes concerning cryptocurrency, increases in energy costs or other macroeconomic conditions and other matters identified in Part I, Item 1A "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and in this Quarterly Report on Form 10-Q. Given this uncertainty regarding the Company's financial condition over the next 12 months from the date these financial statements were issued, the Company has concluded that there is substantial doubt about its ability to continue as a going concern for a reasonable period of time. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Revenue Recognition Revenue From Contracts With Customer - Hosting On January 30, 2023, Greenidge entered into the NYDIG Hosting Agreements, with Greenidge operating miners owned by NYDIG affiliates. Under these agreements, the Company agreed to host, power and provide technical support services, and other related services, to NYDIG affiliates’ mining equipment at certain Greenidge facilities for a term of five years. The terms of such arrangements requires NYDIG affiliates to pay a reimbursement fee that covers the cost of power and direct costs associated with management of the mining facilities, a hosting fee as well as a gross profit-sharing arrangement. Under the NYDIG Hosting Agreements, NYDIG affiliates are required to provide Greenidge an upfront security deposit, pay a configuration fee for the setup of new or relocated miners, and pay for repairs and parts consumed in non-routine maintenance (i.e., units that are out of service for more than 12 hours). Datacenter Hosting Revenue The Company generates revenue from contracts with customers from providing hosting services to a single third-party customer. Hosting revenue is recognized as services are performed on a variable basis. The Company recognizes variable hosting revenue each month as the uncertainty related to the consideration is resolved, hosting services are provided to its customer, and its customer utilizes the hosting service (the customer simultaneously receives and consumes the benefits of the Company's performance). The Company's performance obligation related to these services is satisfied over time. The Company recognizes revenue for services that are performed on a consumption basis (the amount of electricity utilized by the customer) as well as through a fixed fee that is earned monthly and a profit sharing component based on the net proceeds earned by the customer in the month from bitcoin mining activities. The Company bills its customer at the beginning of each month based on the anticipated consumption under the contract. Invoices are collected in the month of invoicing under the terms of the contract. The Company recognizes revenue based on actual consumption in the period and invoices adjustments in subsequent periods or retains credits toward future consumption. Cryptocurrency Mining Revenue Greenidge has entered into digital asset mining pools by executing contracts with the mining pool operators to provide computing power to the mining pool. The contracts are terminable at any time at no cost by either party and Greenidge’s enforceable right to compensation begins only when, and lasts as long as, Greenidge provides computing power to the mining pool operator. In exchange for providing computing power, Greenidge is entitled to a fractional share of the cryptocurrency award the mining pool operator theoretically receives less digital asset transaction fees to the mining pool operator. The agreements entered into with the pool operators payout based on a Full-Pay-Per-Share payout formula, which is based on a conceptual formula that calculates the hash rate provided by Greenidge to the mining pool as a percentage of total network hash rate and other inputs. Under this payout formula, Greenidge is entitled to consideration upon the provision of computing power to the pool even if a block is not successfully placed by the pool operator. Revenue is measured as the value of the fractional share of the cryptocurrency award received from the pool operator, which has been reduced by the transaction fee retained by the pool operator. Providing computing power in digital asset transaction verification services is an output of Greenidge’s ordinary activities. The provision of such computing power is the only performance obligation in Greenidge’s contracts with mining pool operators. The cryptocurrency that Greenidge receives as transaction consideration is noncash consideration, which Greenidge measures at fair value on the date received at the liquidation price received in the sale of the bitcoin reward, which is not materially different than the fair value at the contract inception or the time Greenidge has earned the award from the pools. The awards are received each day for the previous day's revenue and are automatically sold shortly after receipt. The consideration is all variable based on the amount of computing power provided by Greenidge and the total network hash rate and it is probable that a significant reversal of the consideration will not occur. Pool fees paid by miners to pooling operators are based on a fixed percentage of the theoretical bitcoin block reward and network transaction fees received by miners. Pooling fees are netted against daily bitcoin payouts. Greenidge does not expect any material future changes in pool fee percentages paid to pooling operators. Digital Assets Digital assets, primarily consisting of bitcoin, are included in current assets in the accompanying consolidated balance sheets. Digital assets are classified as indefinite-lived intangible assets in accordance with ASC 350, Intangibles – Goodwill and Other , and are accounted for in connection with Greenidge’s revenue recognition policy. Digital assets held are considered an intangible asset with an indefinite useful life, which is not amortized but assessed for impairment annually, or more frequently, when events or changes in circumstances occur indicating that it is more likely than not that the indefinite-lived asset is impaired. The Company performs an analysis each period to identify whether events or changes in circumstances, principally decreases in the quoted prices on principal markets, indicate that it is more likely than not that its digital assets are impaired. Digital assets are considered impaired if the carrying value is greater than the lowest daily quoted prices at any time during the period. For quoted prices of bitcoin, the Company uses a source that publishes daily cryptocurrency trading metrics from information from multiple exchanges and uses an algorithm that factors the confidence from the distribution of prices reported by the exchanges. Subsequent reversal of impairment losses is not permitted. There were no impairments recorded during 2023. The Company assessed its digital assets for impairment, recorded an impairment of $0.1 million during the three and six months ended June 30, 2022, which is included in Other income, net on the consolidated statements of operations. The Company no longer holds bitcoin assets in custody wallets. As of September 30, 2022, the Company’s digital assets consisted of approximately 29.0 bitcoins. The Company considers the conversion of digital assets into U.S. dollars as a part of its normal operating activities and includes the impact of that conversion in Net cash flow (used for) provided by operating activities from continuing operations on the Consolidated Statements of Cash Flows. Digital Assets at December 31, 2022 348 Revenues from digital asset production 17,033 Sale of digital assets (17,381) Digital assets at September 30, 2023 — Recent Accounting Pronouncements, Adopted There were not any recently adopted or newly issued accounting pronouncements, that have had, or are expected to have, a material impact on the Company's condensed consolidated financial statements and disclosures.

ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS	9 Months Ended
ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS	Sep. 30, 2023
Discontinued Operations and Disposal Groups [Abstract]
ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS	ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS A business is classified as held for sale when management having the authority to approve the action commits to a plan to sell or exit the business, the sale or exit is probable to occur during the next 12 months at a price or cost that is reasonable in relation to its current fair value and certain other criteria are met. A business classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. When the carrying amount of the business exceeds its estimated fair value less cost to sell, a loss is recognized and updated each reporting period as appropriate. A business classified as held for sale should be reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on a reporting entity's operations and financial results. Support.com The contract for Support.com's largest customer was not renewed upon expiration on December 31, 2022. As a result of this material change in the business, management and the board of directors made the determination to consider various alternatives for Support.com, including the disposition of assets. At December 31, 2022, the Company classified the Support.com business as held for sale and discontinued operations in the condensed consolidated financial statements as a result of its strategic shift to strictly focus on its cryptocurrency datacenter and power generation operations. In January 2023, Greenidge completed the sale of a portion of the assets of Support.com for net proceeds of approximately $2.6 million. In June 2023, the Company entered into a purchase and sale agreements with third parties in order to sell certain remaining assets and liabilities, including the transfer of remaining customer contracts, for net proceeds of approximately $0.4 million. The Company has ended all Support.com operations as of September 30, 2023; therefore, the remaining assets and liabilities of Support.com have been presented as current at September 30, 2023 and December 31, 2022. The remaining assets and liabilities consist primarily of remaining receivables and refundable deposits, payables and accrued expenses associated with the closing of operations and foreign tax liabilities. Major classes of assets and liabilities consist of the following: $ in thousands September 30, 2023 December 31, 2022 Assets: Accounts receivable $ 472 $ 3,996 Prepaid expenses and other current assets 178 1,253 Current assets held for sale 650 5,249 Property and equipment, net — 743 Other assets 457 481 Long-term assets held for sale 457 1,224 Loss on classification to held for sale (600) — Assets held for sale 507 6,473 Liabilities: Accounts payable 64 191 Accrued expenses 803 3,351 Current liabilities held for sale 867 3,542 Other long-term liabilities — 432 Long-term liabilities held for sale — 432 Liabilities held for sale $ 867 $ 3,974 Financial results from discontinued operations consist of the following: Three Months Ended Nine Months Ended $ in thousands 2023 2022 2023 2022 Revenue $ 378 $ 7,474 $ 4,223 $ 24,387 Cost of revenue - services and other (exclusive of depreciation and amortization) (957) (3,660) (4,425) (11,304) Depreciation and amortization — (324) — (979) Selling, general and administrative (1,353) (2,451) (3,265) (7,831) Merger and other costs (154) (242) (684) (940) Gain on asset disposal — — 4,162 — Loss on assets classified as held for sale 1,135 — (600) — Other (loss) income, net (127) 18 (107) 36 Pretax income from discontinued operations (1,078) 815 (696) 3,369 Provision for income taxes — 79 — 162 (Loss) income from discontinued operations, net of tax $ (1,078) $ 736 $ (696) $ 3,207 The Company’s effective income tax rate from discontinued operations for the three months ended September 30, 2023 and 2022 was 0% and 9.7%, respectively, and for the nine months ended September 30, 2023 and 2022 was 0% and 4.8%, respectively, primarily due to foreign rate differences. South Carolina Datacenter In August 2023, in connection with a non-binding term sheet that the Company entered into with NYDIG in June to effect a deleveraging transaction, the Company completed an electrical upgrade at its South Carolina facility increasing the capacity to 44 MW. Upon completion of this expansion, on August 10, 2023, the Company and NYDIG amended the NYDIG Hosting Agreements to increase the number of miners being hosted by Greenidge utilizing all of the expansion. The NYDIG Hosting Agreements were amended in furtherance of the broader transaction contemplated by the non-binding term sheet pursuant to which the Company would sell to NYDIG all of the upgraded mining facilities at the South Carolina site and would also subdivide and sell to NYDIG the approximately 22 acres of land on which the facilities are located. The South Carolina Datacenter long-lived assets are presented as current assets held for sale as of September 30, 2023. The Company completed the sale on November 9, 2023 (see Note 14, Subsequent Events).

On January 30, 2023, Greenidge entered into an agreement regarding its 2021 and 2022 Master Equipment Finance Agreements with NYDIG. During the nine months ended September 30, 2023, the Company transferred ownership of bitcoin mining equipment with net book value of $50.0 million and miner deposits of $7.4 million that remained accrued to Greenidge for previous purchases of mining equipment with a bitcoin miner manufacturer and the related debt was canceled pursuant to a debt settlement agreement entered into with NYDIG. There was no gain or loss recognized on the sales as these assets. The Company recognized a gain on the sale of assets of $1.8 million, which primarily related to the sale of bitcoin miner manufacturer coupons, including $1.2 million that were transferred as part of the debt restructuring agreement with NYDIG. Impairment The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine recoverability of a long-lived asset, management evaluates whether the estimated future undiscounted net cash flows, based on prevailing market conditions, from the asset are less than its carrying amount. If impairment is indicated, the long-lived asset is written down to fair value. The Company evaluated the recoverability of the South Carolina facility classified as Held for Sale (see note 3, Assets Held for Sale and Discontinued Operations ) as of September 30, 2023. The Company is evaluating future uses of the remaining real estate assets in South Carolina, which includes the land and the original building which was classified as construction in process as it was not used in cryptocurrency mining. The impairment assessment was performed using a market approach. An impairment charge of $4 million was recorded for the three month period ended September 30, 2023, which is the remaining value of the building which was determined to no longer be recoverable. During the nine months ended September 30, 2022, as a result of the significant reduction in the price of bitcoin and increased energy prices during 2022, the Company’s results of operations, as well as income expectations, were negatively impacted resulting in the recognition of noncash impairment charges of $71.5 million to reduce the net book value of the long-lived assets to fair value. Fair value was determined utilizing the market approach, relying on the guideline public company method. Our guideline public company method incorporates revenue and hash rate multiples from other publicly traded companies with operations and other characteristics similar to Greenidge. The table below provides a summary of the impairment by category of asset for the nine months ended September 30, 2022: $ in thousands Land $ 5,000 Plant infrastructure 24,400 Miners 20,945 Miner Facility Infrastructure 990 Equipment 190 Software 70 Coal ash impoundment 925 Construction in process 18,980 Total $ 71,500

Senior Secured Loan On March 21, 2022, Greenidge, as guarantor, together with its wholly-owned subsidiaries GTX Gen 1 Collateral LLC, GNY Collateral LLC and GSC Collateral LLC (collectively, the "Borrowers") entered into a Master Equipment Finance Agreement (the "NYDIG Financing Agreement") with NYDIG, as lender, whereby NYDIG agreed to lend to the Borrowers approximately $81 million under loan schedules that were partially funded for approximately $54 million in March 2022, with additional funding of $17 million through December 31, 2022, to finance the acquisition of certain miners and related equipment (the "Financed Equipment"). The Borrowers' obligations under the NYDIG Financing Agreement were fully and unconditionally guaranteed by Greenidge. Outstanding borrowings under the NYDIG Financing Agreement were secured by all assets of the Borrowers, including without limitation, the Financed Equipment and proceeds thereof (including bitcoin). The loan schedules bore interest at a rate of 13% per annum and had terms of 25 months. Certain loan schedules were interest-only for a specified period and otherwise payments on loan schedules included both an interest and principal payment. Pursuant to the terms of the NYDIG Financing Agreement, the Borrowers and with certain exceptions, the Company, were subject to certain covenants and restrictive provisions which, among other things limited: the Borrowers’ ability to incur additional indebtedness for borrowed money; additional liens on the collateral or the equity interests of any of the Borrowers; consolidations or mergers including the Borrowers or the Company unless such would not constitute a Change in Control (as defined therein); disposing of the collateral or any portion of the collateral with certain exceptions; the Borrowers’ ability to make certain restricted payments and investments; and the ability to create certain direct obligations of the Borrowers or the Company unless the NYDIG Financing Agreement is at least pari passu in right of payment; each of which were subject to customary and usual exceptions and baskets. The loans under the NYDIG Financing Agreement could not be voluntarily partially prepaid, but could be prepaid in whole subject to a make-whole calculation. The NYDIG Financing Agreement is denoted in the table above as "Equipment Financings: A - D and F." At December 31, 2022, Greenidge owed a payment of principal and interest in the amount of approximately $1.0 million due on December 25, 2022. Prior to defaulting on any payments, the Company and NYDIG entered into a waiver that stated both parties agreed that failure to pay the December 25, 2022 and the January 10, 2023 payments when due would not be an event of default if payment was made in full by January 27, 2023. On January 30, 2023, the Company concurrently entered into a debt settlement agreement (the "Debt Settlement Agreement"), the Asset Purchase Agreement (the "NYDIG Purchase Agreement"), and a Senior Secured Loan Agreement (the "Senior Secured Loan") with NYDIG in order to refinance and replace certain outstanding indebtedness under certain Master Equipment Financing Agreements and related loan documentation (the "MEFAs"). The $75.8 million in debt previously outstanding under the MEFAs was reduced by $58.5 million pursuant to the Debt Settlement Agreement and the remaining $17.3 million outstanding under the MEFAs was refinanced. In exchange for this reduction in debt, the Company transferred under the NYDIG Purchase Agreement $50.0 million of bitcoin miners to NYDIG and $8.5 million of miner deposits and coupons that remained accrued to Greenidge for previous purchases of mining equipment with a bitcoin miner manufacturer. As part of the Debt Settlement Agreement, the Company entered into the Senior Secured Loan Agreement, as borrower, with NYDIG, as administrative agent and as collateral agent and is denoted in the table above as "Senior Secured Loan". The Company evaluated the amendment under ASC 470-50, "Debt Modification and Extinguishment", and concluded that the updated terms qualified as a debt modification; therefore, no gain or loss was recorded. The initial principal balance under the Secured Loan (the "Refinanced Amount") was approximately $17.3 million. Interest is payable monthly at an interest rate of 15% per annum, computed on the basis of a 360 day year of twelve 30-day months through January 30, 2025. The Secured Loan includes clauses requiring the Company to maintain cash balances in excess of $10 million, and failure to maintain this balance may be considered an event of default by the lender. The Secured Loan contains customary representations, warranties and covenants including restrictions on indebtedness, liens, restricted payments and dividend, investments, asset sales and similar covenants and contains customary events of default. In addition, the Secured Loan allowed for a voluntary prepayment of the loan in kind of approximately $10.2 million by transferring ownership of certain mining infrastructure assets to NYDIG if NYDIG entered into a binding agreement by April 30, 2023, facilitated by Greenidge, securing rights to a site for a future mining facility. The Company was informed on April 30, 2023 that NYDIG would not be entering into the binding agreement for the future mining facility and that portion of the debt remained outstanding, and as a result, accrued interest of approximately $0.4 million was capitalized into the principal balance at April 30, 2023. In order to facilitate the transactions contemplated by a non-binding term sheet associated with the sale of the Company's South Carolina mining site to NYDIG, on August 11, 2023, NYDIG granted a limited waiver (the "Limited Waiver") to the Company with respect to reducing the Company’s minimum cash requirement from $10 million to $6 million and agreed to amend the NYDIG Senior Secured Loan on August 21, 2023 to extend the waiver of the minimum cash requirement as well as to suspend interest and principal payments due under both the NYDIG Senior Loan and the B Riley Commercial Note until the earlier of (i) the completion of the transactions contemplated by the non-binding term sheet, or (ii) December 29, 2023. On November 9, 2023, the Company completed the sale of the South Carolina mining site to NYDIG which resulted in the settlement of the Senior Secured Loan as part of the consideration received in the sale. This settlement resulted in the termination of all liens, mortgages and security interests previously securing the loan, as well as all related covenants. See note 14, Subsequent Events for further details. Secured Promissory Note On March 18, 2022, Greenidge issued a secured promissory note, as borrower, in favor of B. Riley Commercial as noteholder (the "Noteholder"), evidencing a $26.5 million aggregate principal amount loan by B. Riley Commercial to Greenidge (the "Secured Promissory Note"). The Secured Promissory Note is guaranteed by certain of Greenidge’s wholly-owned subsidiaries: Greenidge South Carolina LLC, GSC RE LLC and 300 Jones Road LLC. The loan outstanding under the Secured Promissory Note originally bore interest at a rate of 6% per annum and originally matured on July 20, 2022, subject to up to five 30-day extensions, through December 2022, that could have been e l ected by Greenidge provided no Event of Default (as defined therein) occurred and is continuing and Greenidge pays an Exit Fee (as defined therein) to the B. Riley Commercial. Pursuant to the terms of the Secured Promissory Note, Greenidge and its subsidiaries were subject to certain covenants and restrictive provisions which will, among other things, limit their ability to incur additional indebtedness for borrowed money or additional liens other than debt and liens permitted pursuant to the Secured Promissory Note; consolidate or merge unless Greenidge survives; or transfer all or substantially all of their assets; make certain restricted payments or investments; have a Change of Control (as defined therein); modify certain material agreements; and engage in certain types of transactions with affiliates; each of which are subject to customary and usual exceptions and baskets. The Secured Promissory Note is secured by a first priority mortgage lien on certain real property together with related improvements, fixtures and personal property located at Greenidge's South Carolina Facility. Greenidge’s obligations under the Secured Promissory Note may be prepaid in whole or in part without penalties or fees. On August 10, 2022, Greenidge and B. Riley Commercial agreed to amend the terms of the Secured Promissory Note, by extending the maturity to June 2023, reducing scheduled monthly amortization payments and revising the interest rate to 7.5%. The Exit Fees (as defined therein) associated with the four 30-day extensions subsequent to August 10, 2022, were accelerated and added to the principal balance as of that date. The principal balance following the amendment was $16.4 million as of August 10, 2022. Additionally mandatory repayments of the Secured Promissory Note were revised, such that 65% of the net cash proceeds received from sales of stock under the Equity Purchase Agreement would be paid to B. Riley Commercial to repay the Secured Promissory Note. The Company evaluated the amendment under ASC 470-50, "Debt Modification and Extinguishment", and concluded that the updated terms qualified as a debt modification, and therefore, no gain or loss was recorded. On January 13, 2023, Greenidge and B. Riley Commercial entered into a Waiver and Acknowledgement Letter (the "B Riley Waiver") regarding the terms of the Amended and Restated Bridge Promissory Note dated August 10, 2022 executed by Greenidge in favor of B. Riley Commercial. Under the B Riley Waiver, B. Riley Commercial agreed that Greenidge’s failure to pay the approximately $1.5 million payment of principal and interest due under the BRCC Note on December 20, 2022 would not be an event of default if that payment were made in full by the earlier of January 20, 2023 or the date that Greenidge and B. Riley Commercial enter into a mutually satisfactory amendment to the BRCC Note addressing, among other things, future amortization requirements under the Secured Promissory Note. The waiver left the due dates for other scheduled payments under the BRCC Note unaffected. On January 30, 2023, Greenidge entered into the Consent and Amendment No. 1 to the Promissory Note (the "B. Riley Amendment") with B. Riley Commercial. The B. Riley Amendment modified the payment dates and principal and interest payment amounts under the Promissory Note, requiring no principal and interest payments until June 2023 and monthly payments thereafter through November 2023. Under the terms of the B. Riley Amendment, each of B. Riley Commercial and Atlas Holdings LLC ("Atlas"), or an affiliate thereof, purchased $1 million of Greenidge’s Class A common stock under the ATM Agreement. B. Riley Commercial purchased common stock on a principal basis at $7.50 per share and Atlas or its affiliate purchased common stock at market prices through B. Riley acting as sales agent. Greenidge also paid a $1 million dollar amendment fee to B. Riley Commercial, payable by the delivery of Greenidge Class A common stock to B. Riley Commercial, as principal under the ATM Agreement, at a price of $7.50 per share. Under the B. Riley Amendment, Greenidge is required to make mandatory monthly debt repayments under the Promissory Note of 15% of the net proceeds of sales of equity, including sales under the ATM Agreement and the equity purchase agreement. The monthly principal amortization payments are $1.5 million beginning June 20, 2023. The Company evaluated the amendment under ASC 470-50, "Debt Modification and Extinguishment", and concluded that the updated terms qualified as a debt modification, therefore, no gain or loss was recorded. On July 20, 2023, NYDIG purchased the secured promissory note from B. Riley Commercial. Under the Limited Waiver discussed in the description of the Senior Secured Loan, NYDIG agreed to amend the NYDIG the Secured Promissory Note on or before August 21, 2023 to suspend interest and principal payments due under the B Riley Commercial Note until the earlier of (i) the completion of the transactions contemplated by the non-binding term sheet, or (ii) December 29, 2023. On November 9, 2023, the Company completed the sale of the South Carolina mining site to NYDIG which resulted in the settlement of the Secured Promissory Note as part of the consideration received in the sale. This settlement resulted in the termination of all liens, mortgages and security interests previously securing the loan, as well as all related covenants. See note 14, Subsequent Events for further details. Senior Unsecured Notes During the fourth quarter of 2021, the Company sold $72.2 million of 8.50% Senior Notes due October 2026 (the "Notes") pursuant to the Company's registration statement on Form S-1.

EARNINGS PER SHARE	Sep. 30, 2023
Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHAREThe Company calculates basic earnings per share by dividing the net income (loss) by the weighted average number of shares of common stock outstanding for the period. The diluted earnings per share is computed by assuming the exercise, settlement, and vesting of all potential dilutive common stock equivalents outstanding for the period using the treasury stock method. The following table sets forth a reconciliation of the numerator and denominator used to compute basic earnings and diluted per share of common stock.

In April 2023, the stockholders approved an amendment and restatement of the Company's 2021 Equity Plan to increase the maximum aggregate number of shares of Class A common stock that may be issued for all purposes under the Plan by 500,000 shares of Class A common stock from 383,111 to 883,111 shares of Class A common stock and to remove the counting of shares of Class A common stock granted in connection with awards other than stock options and stock appreciation rights against the total number of shares available under the Plan as two shares of Class A common stock for every one share of Class A common stock granted in connection with such award. For the nine months ended September 30, 2023, no additional shares had been granted under the 2021 Equity Plan. In October 2022, the Company registered 307,684 shares of Class A common stock, outside of the 2021 Equity Plan, that were reserved for issuance upon the vesting and exercise of non-qualified stock options inducement grants. Restricted Common Stock Unit Awards Restricted stock unit ("RSU") awards are generally eligible to vest over a three-year period. The Company’s unvested RSU awards activity for the nine months ended September 30, 2023 is summarized below: RSUs Weighted Average Unvested at December 31, 2022 24,729 $ 68.80 Vested (12,681) $ 61.69 Unvested at September 30, 2023 12,048 $ 76.28 The value of RSU grants is measured based on their fair market value on the date of grant and amortized over their requisite service periods. There were no grants awarded during the three months ended September 30, 2023. At September 30, 2023, there was approximately $0.5 million of total unrecognized compensation cost related to unvested restricted stock rights, which is expected to be recognized over a remaining weighted-average vesting period of less than 1 year. Common Stock Options The Company’s common stock options activity for the nine months ended September 30, 2023 is summarized below: Options Weighted Average Weighted Average Aggregate Outstanding at December 31, 2022 364,185 $ 20.46 Forfeited (4,538) $ 62.50 Outstanding at September 30, 2023 359,647 $ 19.92 8.80 $ 1,471 Exercisable as of September 30, 2023 47,450 $ 59.22 7.41 $ 194 The value of common stock option grants is measured based on their fair market value on the date of grant and amortized over their requisite service periods. At September 30, 2023, there was approximately $2.2 million of total unrecognized compensation cost related to unvested common stock options, which is expected to be recognized over a remaining weighted-average vesting period of approximately 2.0 years. Stock-Based Compensation The Company recognized stock-based compensation expense of $0.5 million and $0.4 million during the three months ended September 30, 2023 and 2022, respectively and $1.5 million and $1.0 million during the nine months ended September 30, 2023 and 2022, respectively.

INCOME TAXES	Sep. 30, 2023
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. In addition, the effect of changes in enacted tax laws or rates or tax status is recognized in the interim period in which the change occurs. The effective tax rate for the three and nine months ended September 30, 2023 was 0.0% which was lower than the statutory rate of 21% because the Company has recognized a full valuation allowance on its deferred tax assets. The Company continued to evaluate the realizability of deferred tax assets and, due to continued reduced profitability, concluded that a valuation allowance should continue to be recognized for any deferred tax assets generated during the quarter. As a result, there was no net income tax benefit recorded for pretax losses of the U.S. operations in the three months and nine months ended September 30, 2023.

In exchange for the sale to NYDIG of the upgraded 44 MW South Carolina mining facilities and the subdivided real estate of approximately 22 acres of land, Greenidge received total consideration of approximately $28 million: ◦ The Senior Secured Loan with NYDIG with remaining principal of approximately $17.7 million was extinguished; ◦ The B Riley Commercial Secured Promissory Note with remaining principal of approximately $4.1 million as of September 30, 2023, which NYDIG purchased from B. Riley Commercial on July 20, 2023 at par was extinguished; ◦ A cash payment of approximately $4.5 million, and ◦ The Company will also receive bonus payments earned of approximately $1.6 million as a result of the completion of the expansion of the upgraded mining facility and the facility's uptime performance, which are payable at the completion of the transition services period, which is anticipated to occur in December 2023. In conjunction with the sale, the Company and NYDIG terminated the South Carolina Hosting Order. As a result, at the time of closing the Company returned NYDIG's security deposit, which are included in other long-term liabilities as of September 30, 2023, resulting in a cash outflow of $2.2 million. Within thirty days of closing, the Company also expects to receive a cash inflow of $3.5 million from the return of its security deposit held by the local utility, which was included in prepaid expenses and other assets as of September 30, 2023. Additionally, the Company paid the remaining accrued interest on the Senior Secured and Secured Promissory Note of $0.9 million. The Company also settled certain third party transaction costs and Greenidge's share of local taxes of $0.5 million. Following the completion of the South Carolina Facility sale, the Company continues to own approximately 153 acres of land in South Carolina, and is assessing potential uses of the remaining site, which may include the sale of the property. The NYDIG Hosting Agreements related to the New York Facility were not impacted by this transaction and remain in place.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition Revenue From Contracts With Customer - Hosting On January 30, 2023, Greenidge entered into the NYDIG Hosting Agreements, with Greenidge operating miners owned by NYDIG affiliates. Under these agreements, the Company agreed to host, power and provide technical support services, and other related services, to NYDIG affiliates’ mining equipment at certain Greenidge facilities for a term of five years. The terms of such arrangements requires NYDIG affiliates to pay a reimbursement fee that covers the cost of power and direct costs associated with management of the mining facilities, a hosting fee as well as a gross profit-sharing arrangement. Under the NYDIG Hosting Agreements, NYDIG affiliates are required to provide Greenidge an upfront security deposit, pay a configuration fee for the setup of new or relocated miners, and pay for repairs and parts consumed in non-routine maintenance (i.e., units that are out of service for more than 12 hours). Datacenter Hosting Revenue The Company generates revenue from contracts with customers from providing hosting services to a single third-party customer. Hosting revenue is recognized as services are performed on a variable basis. The Company recognizes variable hosting revenue each month as the uncertainty related to the consideration is resolved, hosting services are provided to its customer, and its customer utilizes the hosting service (the customer simultaneously receives and consumes the benefits of the Company's performance). The Company's performance obligation related to these services is satisfied over time. The Company recognizes revenue for services that are performed on a consumption basis (the amount of electricity utilized by the customer) as well as through a fixed fee that is earned monthly and a profit sharing component based on the net proceeds earned by the customer in the month from bitcoin mining activities. The Company bills its customer at the beginning of each month based on the anticipated consumption under the contract. Invoices are collected in the month of invoicing under the terms of the contract. The Company recognizes revenue based on actual consumption in the period and invoices adjustments in subsequent periods or retains credits toward future consumption. Cryptocurrency Mining Revenue Greenidge has entered into digital asset mining pools by executing contracts with the mining pool operators to provide computing power to the mining pool. The contracts are terminable at any time at no cost by either party and Greenidge’s enforceable right to compensation begins only when, and lasts as long as, Greenidge provides computing power to the mining pool operator. In exchange for providing computing power, Greenidge is entitled to a fractional share of the cryptocurrency award the mining pool operator theoretically receives less digital asset transaction fees to the mining pool operator. The agreements entered into with the pool operators payout based on a Full-Pay-Per-Share payout formula, which is based on a conceptual formula that calculates the hash rate provided by Greenidge to the mining pool as a percentage of total network hash rate and other inputs. Under this payout formula, Greenidge is entitled to consideration upon the provision of computing power to the pool even if a block is not successfully placed by the pool operator. Revenue is measured as the value of the fractional share of the cryptocurrency award received from the pool operator, which has been reduced by the transaction fee retained by the pool operator. Providing computing power in digital asset transaction verification services is an output of Greenidge’s ordinary activities. The provision of such computing power is the only performance obligation in Greenidge’s contracts with mining pool operators. The cryptocurrency that Greenidge receives as transaction consideration is noncash consideration, which Greenidge measures at fair value on the date received at the liquidation price received in the sale of the bitcoin reward, which is not materially different than the fair value at the contract inception or the time Greenidge has earned the award from the pools. The awards are received each day for the previous day's revenue and are automatically sold shortly after receipt. The consideration is all variable based on the amount of computing power provided by Greenidge and the total network hash rate and it is probable that a significant reversal of the consideration will not occur. Pool fees paid by miners to pooling operators are based on a fixed percentage of the theoretical bitcoin block reward and network transaction fees received by miners. Pooling fees are netted against daily bitcoin payouts. Greenidge does not expect any material future changes in pool fee percentages paid to pooling operators.
Recent Accounting Pronouncements, Adopted	Recent Accounting Pronouncements, Adopted There were not any recently adopted or newly issued accounting pronouncements, that have had, or are expected to have, a material impact on the Company's condensed consolidated financial statements and disclosures.
Digital Assets	Digital Assets Digital assets, primarily consisting of bitcoin, are included in current assets in the accompanying consolidated balance sheets. Digital assets are classified as indefinite-lived intangible assets in accordance with ASC 350, Intangibles – Goodwill and Other , and are accounted for in connection with Greenidge’s revenue recognition policy. Digital assets held are considered an intangible asset with an indefinite useful life, which is not amortized but assessed for impairment annually, or more frequently, when events or changes in circumstances occur indicating that it is more likely than not that the indefinite-lived asset is impaired. The Company performs an analysis each period to identify whether events or changes in circumstances, principally decreases in the quoted prices on principal markets, indicate that it is more likely than not that its digital assets are impaired.
