Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Description of Business

1. Organization and Description of Business

Greenidge Generation Holdings Inc. (“Greenidge”) and Subsidiaries (collectively, the “Company”) owns and operates a vertically integrated bitcoin mining and power facility located in Dresden, New York. The Company’s bitcoin mining capacity generates revenue in the form of bitcoin and U.S. dollars by earning bitcoin with application-specific integrated circuit computers (“ASICs” or “miners”) that are owned by the Company as rewards and transaction fees for supporting the global bitcoin network. Additionally, the Company generates revenues in U.S. dollars to a lesser extent from third parties for hosting and maintaining their ASICs. The Company also sells surplus electricity generated by its power plant, and not consumed in bitcoin mining operations, to the New York Independent System Operator (“NYISO”) power grid at prices set on a daily basis through the NYISO wholesale market. In addition, the Company receives revenues from the sale of its capacity and ancillary services in the NYISO wholesale market. The consolidated financial statements include the accounts of the following entities:

•

Greenidge (a Delaware corporation). Greenidge was formed in 2021 to oversee and manage the following entities:

•

Greenidge Generation Blocker Inc. (“GGB”), a Delaware corporation and a wholly owned subsidiary of Greenidge

•

Greenidge Generation Holdings LLC (“GGH”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Generation, LLC (“GG”), a New York limited liability company and a wholly owned subsidiary of Greenidge

•

Lockwood Hills, LLC (“LH”), a New York limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Solar, LLC (“GS”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Pipeline, LLC (“GP”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Pipeline Properties Corporation (“GPP”), a New York Corporation and a wholly owned subsidiary of Greenidge

•

Greenidge Markets and Trading, LLC (“GMT”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Secured Lending, LLC (“SL”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge

•

Greenidge Blocker Corp. (“Blocker”), a Delaware corporation and a consolidated variable interest entity

•

Greenidge Coin, LLC (“GC”), a Delaware limited liability company and a wholly owned subsidiary of Greenidge. In January 2021, GC merged into GG and GC was subsequently dissolved.

Variable Interest Entities

The Company evaluates its interests in variable interest entities (“VIE”) and will consolidate any VIE in which it has a controlling financial interest and is deemed to be the primary beneficiary. A controlling financial interest has both of the following characteristics: (1) the power to direct the activities of the VIE that most significantly impact its economic performance; and (2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could be significant to the VIE. If both characteristics are met, the Company considers itself to be the primary beneficiary and therefore will consolidate that VIE into its consolidated financial statements.

Consolidation of a Variable Interest Entity

On October 2, 2019, Blocker, a related entity through common ownership, purchased 15,000 preferred units of GC for $15,000. Blocker was formed for the sole purpose of making a capital investment into GC so that GC could then provide a loan to GGH. The purpose of the loan from GC to GGH was to fund the development of infrastructure necessary for the Company to commence its Bitcoin mining operations.

Accordingly, Blocker is deemed a VIE because Blocker’s operations consist of its investment in GC and consequently, Blocker relies on the operations of the Company to sustain future operating expenses. The Company is deemed the primary beneficiary of the VIE because it is the sole provider of financial support. Accordingly, as of October 2, 2019, the Company consolidated Blocker’s balance sheet and results of operations. On December 31, 2020, Blocker entered into a liquidating distribution agreement with GGH, effectively dissolving Blocker into GGH.

Plan of Merger

On March 19, 2021, the Company entered into a definitive agreement and plan of merger for a business combination with Support.com, Inc., a Delaware corporation (NASDAQ: SPRT).

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of management, the accompanying unaudited condensed interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjusting, considered necessary for a fair presentation of such interim results.

Greenidge is the successor entity for accounting purposes to GGH as a result of the corporate restructuring consummated in January 2021. Pursuant to this restructuring, Greenidge was incorporated in the State of Delaware on January 27, 2021 and on January 29, 2021, entered into an asset contribution and exchange agreement with the owners of GGH, pursuant to which Greenidge acquired all of the ownership interests in GGH in exchange for 7,000,000 shares of Greenidge’s common stock (28,000,000 shares of GGHI Class B Common Stock after the 4-for-1 split in March 2021). As a result of this transaction, GGH became a wholly-owned subsidiary of Greenidge. The financial information presented herein are that of GGH for the periods before January 29, 2021 and Greenidge for the period after January 29, 2021.

The results for the unaudited condensed interim consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2021 or for any future interim period. The unaudited condensed interim consolidated financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed interim consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2020 and notes thereto.

The consolidated financial statements include the accounts of the Company and its subsidiaries as described in Note 1. All significant intercompany accounts and transactions have been eliminated.

Use of estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and notes thereto. Actual results could differ from those estimates.

Significant Accounting Policies

For a detailed discussion about the Company’s significant accounting policies, see the Company’s December 31, 2020 consolidated financial statements.

Emissions Expense and Credits

The Company generates carbon dioxide emissions. As a result, the Company incurs emissions expense and is required to purchase emission credits, which are valued at cost, to offset the liability. The Company participates in the Regional Greenhouse Gas Initiative (“RGGI”), which requires, by law, that the Company remit credits to offset 50% of the Company’s annual emission expense in the following year, for each of the years in the three year control period (January 1, 2018 to December 31, 2020). In February 2021, the Company settled the emissions allowance for the control period. The Company continues to remit credits in accordance with RGGI. The Company recognizes expense on a per ton basis, where one ton is equal to one RGGI credit.

The RGGI credits are recorded on a first in, first out (“FIFO”) basis. The Company incurred emissions expense of $402 and $815 for the three and six months ended June 30, 2021, respectively, and $309 and $473 for the three and six months ended June 30, 2020, respectively, which is included in power and capacity cost of revenue in the accompanying condensed consolidated statements of operations.

Carbon Offset Credits

The Company announced that effective June 1, 2021, it will operate an entirely carbon neutral bitcoin mining operation at its facility in Dresden, New York. The Company plans to purchase voluntary carbon offsets from a portfolio of U.S. greenhouse gas reduction projects as one method to achieve this carbon neutrality. During the second quarter of 2021, the Company purchased $684 of voluntary carbon offset credits. The voluntary carbon offset credits will be expensed to cost of revenues on a specific identification basis when the Company applies it to its net zero goals, which is when the credits are surrendered to the applicable agency.

Asset Retirement Obligations

Asset retirement obligations are legal obligations associated with the retirement of long-lived assets. The obligations represent the present value of the estimated costs for an asset’s future retirement discounted using a credit-adjusted risk-free rate, and are recorded in the period in which the liability is incurred. The liabilities recognized relate to the decommissioning of a coal ash pond for coal combustion residuals (“CCR”), which are subject to Federal and State regulations.

In accordance with Federal law and Accounting Standards Codification (“ASC”) 410-20, Asset Retirement Obligations, the Company recorded an asset retirement obligation of $2,345 and $2,277 at June 30, 2021 and December 31, 2020, respectively. The company expensed $35 and $32 to other income and expense, net during the three months ended June 30, 2021 and 2020, respectively for the accretion of interest for the liability and $68 and $74 during the six months ended June 30, 2021 and 2020, respectively. There were no changes to cash flow estimates related to the coal ash pond asset retirement obligation during the three and six months ended June 30, 2021 or 2020. Estimates are based on various assumptions including, but not limited to, closure cost estimates, timing of expenditures, escalation factors, discount rate of 5.00% and methods for complying with CCR regulations. Additional adjustments to the asset retirement obligations are expected periodically due to potential changes in estimates and assumptions.

Environmental Trust Liability

The Company owns and operates a landfill. As required by the New York State Department of Environmental Conservation (“NYSDEC”), landfills are required to fund a trust to cover closure costs and expenses after the landfill has stopped operating.

The trust is designed to provide funds for 30 years of expenses to maintain a landfill once it is full and has no further source of revenue or in case the owner is defunct and the NYSDEC has to operate the landfill. The landfill is a fully permitted, operational landfill and also acts as a leachate treatment facility. An annual report is completed by a third-party engineering firm to provide environmental compliance and calculate combined closure and post-closure costs, discounted to current year dollars using a discount rate of 4.50%. In lieu of a trust, the Company has negotiated with its largest equity member to maintain a letter of credit guaranteeing the payment of the liability (see Note 6). In accordance with ASC 410-20, the Company has recorded an environmental liability of $4,994 and $4,927 at June 30, 2021 and December 31, 2020, respectively. The letter of credit related to this liability was for $4,994 at June 30, 2021 (see Note 6).

Leases

On January 1, 2021, the Company adopted Accounting Standards Codification (“ASC”) 842, Leases. No lease arrangements were in place as of January 1, 2021. Following guidance in ASC 842, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the condensed consolidated balance sheet. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. The ROU asset is amortized over the lease term. Variable lease expenses, if any, are recorded when incurred.

In calculating the ROU asset and related lease liability, the Company elected to combine lease and non-lease components. The Company excluded short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. Refer to Note 5 for the additional disclosures required by ASC 842.

Cryptocurrency Mining Cost of Revenue

Cost of revenue - cryptocurrency mining consists primarily of natural gas, emissions, payroll and benefits and other direct production costs associated with the megawatts generated for the digital mining operation. Cost of revenue – cryptocurrency mining does not include depreciation and amortization.

Power and Capacity Cost of Revenue

Cost of revenue - power and capacity consists primarily of natural gas, emissions, payroll and benefits and other direct production costs associated with the megawatts generated for the power produced by Greenidge and sold to the grid. Cost of revenue – power and capacity does not include depreciation and amortization.

Selling, General, and Administrative Expenses

Selling, general and administrative expenses consist primarily of administrative payroll and benefits, business development costs, professional fees, and insurance.

Stock-Based Compensation

The Company accounts for share-based payment awards exchanged for services at the estimated grant date fair value of the award. Stock options issued under the Company’s equity incentive plans are granted with an exercise price equal to no less than the market price of the Company’s stock at the date of grant and expire up to ten years from the date of the grants. These options generally vest on the grant date or over a three year period.

The Company estimates the fair value of the stock options grants using the Black-Scholes-Merton option pricing model and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgement.

Expected Term – The expected term of options represents the period that the Company’s stock-based awards are expected to be outstanding on the simplified method, which is the half-life from vesting to the end of its contractual term.

Expected Volatility – The Company computes stock price volatility over expected terms based on reasonable estimates and comparable public companies as the Company had no trading history of its own common stock.

Risk-Free Interest Rate – The Company bases the risk-free interest rate on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend – The Company has never declared or paid any cash dividends on its common shares and does not plan to pay cash dividends in the foreseeable future, and, therefore, uses an expected dividend yield of zero in its valuation models.

Income Taxes

Prior to the formation of Greenidge on January 27, 2021, the Company was treated as a partnership for federal and state income tax purposes. Pursuant to this election, the profit or loss of the Company is reported in the individual income tax returns of the members. Therefore, no provision for Federal or State taxes has been made for the year ended December 31, 2020.

Subsequent to the conversion of GGH to Greenidge, the Company calculates the provision for income taxes in accordance with ASC 740, Income Taxes, (“ASC 740”). The current provision for income taxes represents actual or estimated amounts payable or refundable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. A valuation allowance may be provided to the extent management deems it is more likely than not that deferred tax assets will not be realized. The ultimate realization of net deferred tax assets is dependent upon the generation of future taxable income, in the appropriate taxing jurisdictions, during the periods in which temporary differences, net operating losses and tax credits become realizable. Management believes that it is more likely than not that the Company will realize the benefits of these temporary differences and operating loss and tax credit carryforwards, net of valuation allowances. The Company recognizes and measures tax positions taken or expected to be taken in its tax return based on their technical merit and assesses the likelihood that the positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. Interest and penalties on tax liabilities, if any, would be recorded as incurred in interest expense and other expenses, respectively.

Earnings Per Share

Basic net income per common share attributable to common shareholders is calculated by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share attributable to common shareholders is calculated by dividing net income attributable to common shareholders by the diluted weighted average number of common shares outstanding for the period. Basic and diluted income per common share is not provided for the three and six months ended June 30, 2020 as the Company was organized as an LLC during that period. The Company used the weighted average method in determining earnings per share in consideration of the conversion of participating securities to common shares due to the reorganization in January 2021.

Recent Accounting Pronouncements Not Yet Adopted

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles.

in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. As an emerging growth company, the Company has elected to adopt this pronouncement following the effective date for private companies beginning with periods beginning after December 15, 2021. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Any new accounting standards, not disclosed above, that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.

Recent Accounting Pronouncements, Adopted

In February 2016, the FASB issued Accounting Standards Update ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms greater than 12 months and also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. Subsequent to the issuance of Topic 842, the FASB clarified the guidance through several ASUs; hereinafter the collection of lease guidance is referred to as “ASC 842”. On January 1, 2021, the Company adopted ASC 842. The Company had no leasing arrangements at the beginning of the period of adoption. As a result, no cumulative impact of adopting ASC 842 was recorded. The Company also elected to exclude

leases with a term of 12 months or less in the recognized ROU assets and lease liabilities, when the likelihood of renewal is not probable. Refer to Note 5 for additional disclosures required by ASC 842. The Company determines if an arrangement is a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

The Company entered into a promissory note agreement during 2020 with its largest equity members, Atlas Capital Resources LP and Atlas Capital Resources (P) LP (collectively referred to herein as “Atlas”). Within the agreement, there were two separate loans. One of these related party loans had a June 2021 maturity and a balance of $2,382 at December 31, 2020, and the other loan had a May 2021 maturity with a balance of $1,191 at December 31, 2020. The promissory notes bore interest at 8% per annum calculated on a 360-day year, and interest accrued and compounded on a quarterly basis. All accrued but unpaid interest under the notes was due and payable upon the corresponding note maturity date. Under this promissory note agreement, the Company incurred interest expense of $0 and $22 for the three and six months ended June 30, 2021, respectively. During the three and six months ended June 30, 2020, the company incurred interest expense on related party loans of $273 and $540, respectively, associated with loans that were converted into senior priority units in July 2020.

Atlas obtained a letter of credit from a financial institution in the amount of $4,994 at June 30, 2021, payable to the NYSDEC. This letter of credit guarantees the current value of the Company’s environmental trust liability as discussed in Note 2.

Atlas also obtained a letter of credit from a financial institution in the amount of $3,630 at June 30, 2021, payable to Empire Pipeline Incorporated (“Empire”) in the event the Company should not make contracted payments for costs related to a pipeline interconnection project the Company has entered into with Empire (see Note 11).

Guarantee

An affiliate of Atlas has guaranteed the payment obligation of Greenidge in favor of Emera Energy Services, Inc. under an Energy Management Agreement and an ISDA Master Agreement under which Greenidge may enter into various transactions involving the purchase and sale of gas, electricity and other commodities with Emera Energy Services, Inc. This guaranty is limited to $1.0 million. Atlas had no exposure under the guarantee during the period ended June 30, 2021.

Stockholders Equity

7. STOCKHOLDERS’ EQUITY

Authorized Shares

Greenidge has the authority to issue 520,000,000 shares of capital stock, consisting of 400,000,000 shares of Class A common stock, $0.0001 par value per share, 100,000,000 shares of Class B common stock, $0.0001 par value per share, and 20,000,000 shares of preferred stock, $0.0001 par value per share.

Contribution and Exchange Agreement

In January 2021, GGH LLC completed a corporate restructuring. Pursuant to this restructuring, Greenidge was formed and incorporated in the State of Delaware on January 27, 2021. On January 29, 2021, Greenidge entered into an asset contribution and

exchange agreement with the owners of GGH, in which the GGH owners’ equity interests and outstanding notes payable to related parties and all accrued but unpaid interest were contributed into GGHI in exchange for 7,000,000 shares of Greenidge Class B common stock (28,000,000 shares following the 4-for-1 stock split noted below) (see Note 6). As a result of this transaction, GGH became a wholly-owned subsidiary of GGHI.

Private Placement Offering

In January 2021, Greenidge completed a private placement offering in which 1,620,000 shares of series A redeemable convertible preferred stock was sold at $25 per share. Total net proceeds from the private placement offering were $37,112.

Common Stock

The holders of Class A Common Stock are entitled to one vote per share. The holders of Class B Common Stock are entitled to ten votes per share. Class A and Class B shares issued and outstanding as of June 30, 2021 are 0 and 28,320,000, respectively.

Each share of Class B Common Stock is convertible into one share of Class A Common Stock at the option of the holder upon written notice to the Company. Shares of Class B Common Stock will automatically convert to shares of Class A Common Stock upon a mandatory conversion event as defined in the amended and restated certificate of incorporation dated March 26, 2021.

Preferred Stock

The holders of Preferred Stock are not entitled to voting rights.

If dividends are declared and paid to the holders of common stock, the holders of preferred stock are entitled to a dividend equivalent as if the preferred stock were converted to common stock. Preferred stockholders are also entitled to a paid-kind-dividend of additional shares of preferred stock (capped at 12% of stated value) upon certain events occurring as defined in the amended and restated certificate of incorporation dated March 26, 2021. Such events included failure to file, effectiveness failure, and mandatory redemption failure.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of Greenidge or any deemed liquidation event in which Greenidge is a constituent party, before any payment to the holders of common stock, the holders of preferred stock then outstanding shall be paid out of the funds and assets available for distribution to stockholders an amount per share equal to the stated value for such share, plus an amount per share equal to the stated value of any shares issuable as the result of any accrued, but unpaid, paid-in-kind dividends. If Greenidge’s funds and assets are insufficient to pay such liquidation preference in full, the funds and assets available for distribution shall be distributed ratably to the holders of the shares of preferred stock.

Each share of preferred stock will be automatically converted to four shares of Class B common stock when the Company’s registration statement to register such shares for resale is declared effective by the Securities and Exchange Commission, or, if the Company is not listed within 18 months of the issue date, the shares of preferred stock will convert to common shares based on an initial conversion price of $25 per share of preferred stock.

Liquidation value as of June 30, 2021 is $25 per share.

Common Units

In October 2018, GGH adopted an equity incentive plan and allocated 1,250 common units to the plan. In 2018, GGH awarded 750 restricted units to certain board members, subject to various vesting provisions. At December 31, 2020, there were 730 and 20 vested and unvested, respectively, restricted units. In the event of a change in control of the Company, 100% of the awarded units would vest immediately. Common unit holders are entitled to one vote per common unit, except for such votes or consents that are reserved solely for the holders of preferred units. The Company concluded that the value of the units granted in 2018 was insignificant given historical performance of the Company, no public market, and lack of liquidity. As such, the Company did not recognize any expense related to the common restricted units during the three and six months ended June 30, 2021 and 2020. There were 750 common units issued and outstanding at December 31, 2020. In January 2021, in conjunction with the Private Placement Offering, the 750 GGH common units were converted to shares of Class B Greenidge common stock.

Preferred Units

Preferred unit holders were entitled to one vote per preferred unit. In the event of liquidation or dissolution of GGH, the holders of preferred units were entitled to receive distributions, prior to and in preference to the holders of common units. At December 31, 2020, all preferred units were issued and outstanding. All preferred units were converted to shares of Class B Greenidge common stock in connection with the contribution and exchange agreement.

Senior Priority Units

There were two tranches of Senior Priority Units: Tranche 1 was equal to $13,926 and Tranche 2 was equal to $16,276. Tranche 1 Senior Priority Units were issued to Atlas in July 2020 in exchange for the conversion of certain notes payable due to Atlas and all accrued but unpaid interest thereon. Tranche 2 Senior Priority Units were issued to Atlas in conjunction with Atlas contributing its equity interest in Blocker to GGH. Senior Priority Units had no voting rights.

At December 31, 2020, all senior priority units were issued and outstanding. All senior priority units were converted to shares of Class B Greenidge common stock in connection with the contribution and exchange agreement.

- Definition

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

EQUITY BASED COMPENSATION

6 Months Ended

Jun. 30, 2021

Share-based Payment Arrangement [Abstract]

Equity Based Compensation

8. EQUITY BASED COMPENSATION

In February 2021, Greenidge adopted an equity incentive plan and reserved 3,831,112 shares of common stock for issuance under the plan (the “2021 Equity Plan”).

Restricted Common Stock Unit Awards

During the three and six months ended June 30, 2021, the Company awarded 0 and 616,920 restricted common stock units (“RSUs”), respectively, under the 2021 Equity Plan to directors, which are generally eligible to vest over a three-year period.

The Company’s unvested restricted common stock unit awards activity for the six months ended June 30, 2021 is summarized below:


			Weighted Average
			Grant Date
	RSUs		Fair Value
Unvested at December 31, 2020		-	$	-
Granted		616,920		6.25
Unvested at June 30, 2021		616,920		6.25

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. During the six months ended June 30, 2021, the fair market value of the awards granted totaled $3,856 and as of June 30, 2021, there was approximately $3,427 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 approximately 3 years.

Common Stock Options

The Company’s stock options activity for the six months ended June 30, 2021 is summarized below:


						Weighted Average
				Weighted Average		Remaining
				Exercise Price		Contractual Life
	Options			Per Share		(in years)
Outstanding at December 31, 2020		-		$	-		-
Granted		716,968			6.01		10.00
Exercised		(160,000	)		6.25		0.10
Forfeited		(6,000	)		6.25		9.70
Outstanding at June 30, 2020		550,968			6.01		9.68
Options vested and expected to vest as of June 30, 2021		550,968			6.01		9.68
Options vested and exercisable as of June 30, 2021		257,484		$	5.80		9.64

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. During the six months ended June 30, 2021, the fair market value of the awards granted totaled $1,151 and as of June 30, 2021, there was approximately $438 of total unrecognized compensation cost related to unvested options, which is expected to be recognized over a remaining weighted-average vesting period of approximately 1.2 years.

The intrinsic value of options exercised during the three and six months ended June 30, 2021 was immaterial.

The weighted average assumptions relating to the valuation of stock options granted for the six months ended June 30, 2021 were as follows:

Weighted Average Assumptions:


Weighted Average fair value of grants	$	1.60
Expected volatility		35	%
Expected term (years)		4.5
Risk-free interest rate		0.4	%
Expected dividend yield		0.0	%

Stock-based Compensation

The Company recognized stock-based compensation expense of $406 and $1,063 within selling, general and administrative expenses during the three and six months ended June 30, 2021. No stock-based compensation expense was recognized during the three and six months ended June 30, 2020.

Stock-based compensation expense is included in selling, general and administrative expenses in the accompanying unaudited condensed interim consolidated statements of operations.

INCOME TAXES

6 Months Ended

Jun. 30, 2021

Income Tax Disclosure [Abstract]

Income Taxes

9. 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.

The effective income tax rate as a percentage of income before income taxes was 28.4% and 30.7% for the three and six months ended June 30, 2021, respectively. The effective tax rate for the six months ended June 30, 2021 includes the recognition of a deferred tax liability caused by the reorganization from an LLC to a corporation during the first quarter of 2021 Prior to January 27, 2021, the Company was treated as a partnership for federal and state income tax purposes; therefore, there was no income tax provision or benefit recognized during 2020.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

EARNINGS PER SHARE

6 Months Ended

Earnings Per Share [Abstract]

Earnings Per Share

10. EARNINGS PER SHARE

The 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. Basic earnings per share is applicable only for the period from January 29, 2021 through June 30, 2021, which is the period following the reorganization GGH into Greenidge (as described in Note 2) and presents the period that the Company had outstanding common stock.

Net income attributable to Greenidge	$	2,870		$	4,149
Denominator

Diluted weighted average shares outstanding		35,425			35,245
Earnings per share
Basic	$	0.10		$	0.15
Diluted	$	0.08		$	0.12

Prior to the reorganization, there were no shares of common stock outstanding, and the LLC structure of GGH consisted of member units. The Company analyzed the calculation of earnings per unit for periods prior to the reorganization and determined that it resulted in values that would not be meaningful to the users of these consolidated financial statements. Therefore, earnings per share information has not been presented for the periods during 2020.

For the three and six months ended June 30, 2021 there were no shares excluded from the calculation of diluted earnings per share.

Risks and Uncertainties [Abstract]

Concentrations

12. CONCENTRATIONS

The Company has one major power customer, NYISO, that accounted for 13% and 15% of its revenue for the three and six months ended June 30, 2021, respectively, and 27% for the three and six months ended June 30, 2020. 100% of accounts receivable were due from this customer at June 30, 2021 and December 31, 2020.

For cryptocurrency mining, Greenidge considers its mining pool operators to be its customers. Greenidge has historically used a limited number of pool operators that have operated under contracts with a one-day term, which allows Greenidge the option to change pool operators at any time. Revenue from the Company’s largest pool operator customer accounted for approximately 75% and 73% of total revenue for the three and six months ended June 30, 2021, respectively, and approximately 61% and 65% of total revenue for the three and six months ended June 30, 2020, respectively.

The Company has one major power vendor that accounted for approximately 56% and 59% of cost of revenue for the three and six months ended June 30, 2021, respectively, and approximately 52% and 59% of cost of revenue for the three and six months ended June 30, 2020, respectively.

The United States is presently in the midst of a national health emergency related to a virus, commonly known as Novel Coronavirus (“COVID-19”). The overall consequences of COVID-19 on a national, regional and local level are unknown, but it has the potential to result in a significant economic impact. COVID-19 did not have a material impact on the Company’s operations during the three and six months ended June 30, 2021 and 2020, respectively. The future impact of this situation on the Company and its results and financial position is not presently determinable.

Subsequent Events

14. SUBSEQUENT EVENTS

Subsequent events have been evaluated through September 23, 2021, the date at which the condensed consolidated financial statements were available to be issued, and the Company has concluded that no such events or transactions took place that would require disclosure herein except as stated directly above.

Merger

On September 14, 2021, we consummated transactions contemplated by the Merger Agreement, by and among Greenidge, Support and Merger Sub. As contemplated by the Merger Agreement, Merger Sub merged with and into Support, the separate corporate existence of Merger Sub ceased and Support survived as a wholly owned subsidiary of Greenidge.

Increase in Authorized Capital

On September 13, 2021, we filed an amendment to our certificate of incorporation to increase our authorized capital stock. Following the amendment, our authorized capital stock consists of 2,400,000,000 shares of class A common stock, par value $0.0001 per share, 600,000,000 shares of class B common stock, par value $0.0001 per share, and 20,000,000 shares of preferred stock, par value $0.0001 per share.

Equity Purchase Agreement with B. Riley Principal Capital, LLC

On September 15, 2021, we entered into a common stock purchase agreement (the "Purchase Agreement") with B. Riley Principal Capital, LLC (the "Investor") pursuant to which we have the right to "put" or sell to the Investor up to $500 million of shares of the class A common stock, subject to certain limitations and conditions set forth in the Purchase Agreement, from time to time during the term of the Purchase Agreement. As provided in the Purchase Agreement, we may require the Investor to purchase shares of our class A common stock from time to time by delivering a put notice to the Investor specifying the total number of shares to be purchased. Under the applicable Nasdaq rules, in no event may we issue to the Investor under the Purchase Agreement more than 19.99% of the total number of combined shares of our class A common stock and class B common stock that were outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”), unless we obtain stockholder approval to issue shares in excess of the Exchange Cap in accordance with applicable Nasdaq rules.

The per share purchase price for the shares of class A common stock that we elect to sell to the Investor pursuant to the Purchase Agreement, if any, will be determined by reference to the volume weighted average price of our common stock ("VWAP") during the

applicable purchase date on which we have timely delivered written notice to the Investor directing it to purchase shares under the Purchase Agreement, less a fixed 5% discount, which shall be increased to a fixed 6% discount at such time that we received aggregate cash proceeds of $200 million as payment for all shares of class A common stock purchased by the Investor in all prior sales of class A common stock made under the Purchase Agreement. The Investor will have no obligation to purchase shares pursuant to the purchase agreement to the extent that such purchase would cause the Investor to own more than 4.99% of our issued and outstanding shares of class A common stock.

In connection with the Purchase Agreement, we entered into a registration rights agreement with the Investor pursuant to which we agreed to prepare and file a registration statement registering the resale by the Investor of those shares of our class A common stock to be issued under the Purchase Agreement.

Proposed Registered Notes Offering

On September 20, 2021, we filed a registration statement on Form S-1 (the “Notes Registration Statement”) under the Securities Act pursuant to which we expect to offer senior unsecured notes (the “Notes”) in an underwritten public offering (the “Notes Offering”). The specific terms and tenor of the Notes have not yet been determined, but we currently anticipate an offering size of approximately $100 million with a 15% overallotment option and a tenor of 5 years, with customary redemption features for notes of this type. We intend to use the net proceeds from the Notes Offering for general corporate purposes, including funding future acquisitions and investments, repaying indebtedness, making capital expenditures and funding working capital. The Notes will be issued in minimum denominations of $25.00 and integral multiples of $25.00 in excess thereof. The Offering is subject to market and other conditions, including the effectiveness of the Notes Registration Statement filed under the Securities Act.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of management, the accompanying unaudited condensed interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjusting, considered necessary for a fair presentation of such interim results. Greenidge is the successor entity for accounting purposes to GGH as a result of the corporate restructuring consummated in January 2021. Pursuant to this restructuring, Greenidge was incorporated in the State of Delaware on January 27, 2021 and on January 29, 2021, entered into an asset contribution and exchange agreement with the owners of GGH, pursuant to which Greenidge acquired all of the ownership interests in GGH in exchange for 7,000,000 shares of Greenidge’s common stock (28,000,000 shares of GGHI Class B Common Stock after the 4-for-1 split in March 2021). As a result of this transaction, GGH became a wholly-owned subsidiary of Greenidge. The financial information presented herein are that of GGH for the periods before January 29, 2021 and Greenidge for the period after January 29, 2021. The results for the unaudited condensed interim consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2021 or for any future interim period. The unaudited condensed interim consolidated financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed interim consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2020 and notes thereto. The consolidated financial statements include the accounts of the Company and its subsidiaries as described in Note 1. All significant intercompany accounts and transactions have been eliminated.
Use of estimates	Use of estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and notes thereto. Actual results could differ from those estimates.
Significant Accounting Policies	Significant Accounting Policies For a detailed discussion about the Company’s significant accounting policies, see the Company’s December 31, 2020 consolidated financial statements.
Emissions Expense and Credits	Emissions Expense and Credits The Company generates carbon dioxide emissions. As a result, the Company incurs emissions expense and is required to purchase emission credits, which are valued at cost, to offset the liability. The Company participates in the Regional Greenhouse Gas Initiative (“RGGI”), which requires, by law, that the Company remit credits to offset 50% of the Company’s annual emission expense in the following year, for each of the years in the three year control period (January 1, 2018 to December 31, 2020). In February 2021, the Company settled the emissions allowance for the control period. The Company continues to remit credits in accordance with RGGI. The Company recognizes expense on a per ton basis, where one ton is equal to one RGGI credit. The RGGI credits are recorded on a first in, first out (“FIFO”) basis. The Company incurred emissions expense of $402 and $815 for the three and six months ended June 30, 2021, respectively, and $309 and $473 for the three and six months ended June 30, 2020, respectively, which is included in power and capacity cost of revenue in the accompanying condensed consolidated statements of operations.
Carbon Offset Credits	Carbon Offset Credits The Company announced that effective June 1, 2021, it will operate an entirely carbon neutral bitcoin mining operation at its facility in Dresden, New York. The Company plans to purchase voluntary carbon offsets from a portfolio of U.S. greenhouse gas reduction projects as one method to achieve this carbon neutrality. During the second quarter of 2021, the Company purchased $684 of voluntary carbon offset credits. The voluntary carbon offset credits will be expensed to cost of revenues on a specific identification basis when the Company applies it to its net zero goals, which is when the credits are surrendered to the applicable agency.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations are legal obligations associated with the retirement of long-lived assets. The obligations represent the present value of the estimated costs for an asset’s future retirement discounted using a credit-adjusted risk-free rate, and are recorded in the period in which the liability is incurred. The liabilities recognized relate to the decommissioning of a coal ash pond for coal combustion residuals (“CCR”), which are subject to Federal and State regulations. In accordance with Federal law and Accounting Standards Codification (“ASC”) 410-20, Asset Retirement Obligations, the Company recorded an asset retirement obligation of $2,345 and $2,277 at June 30, 2021 and December 31, 2020, respectively. The company expensed $35 and $32 to other income and expense, net during the three months ended June 30, 2021 and 2020, respectively for the accretion of interest for the liability and $68 and $74 during the six months ended June 30, 2021 and 2020, respectively. There were no changes to cash flow estimates related to the coal ash pond asset retirement obligation during the three and six months ended June 30, 2021 or 2020. Estimates are based on various assumptions including, but not limited to, closure cost estimates, timing of expenditures, escalation factors, discount rate of 5.00% and methods for complying with CCR regulations. Additional adjustments to the asset retirement obligations are expected periodically due to potential changes in estimates and assumptions.
Environmental Trust Liability	Environmental Trust Liability The Company owns and operates a landfill. As required by the New York State Department of Environmental Conservation (“NYSDEC”), landfills are required to fund a trust to cover closure costs and expenses after the landfill has stopped operating. The trust is designed to provide funds for 30 years of expenses to maintain a landfill once it is full and has no further source of revenue or in case the owner is defunct and the NYSDEC has to operate the landfill. The landfill is a fully permitted, operational landfill and also acts as a leachate treatment facility. An annual report is completed by a third-party engineering firm to provide environmental compliance and calculate combined closure and post-closure costs, discounted to current year dollars using a discount rate of 4.50%. In lieu of a trust, the Company has negotiated with its largest equity member to maintain a letter of credit guaranteeing the payment of the liability (see Note 6). In accordance with ASC 410-20, the Company has recorded an environmental liability of $4,994 and $4,927 at June 30, 2021 and December 31, 2020, respectively. The letter of credit related to this liability was for $4,994 at June 30, 2021 (see Note 6).
Leases	Leases On January 1, 2021, the Company adopted Accounting Standards Codification (“ASC”) 842, Leases. No lease arrangements were in place as of January 1, 2021. Following guidance in ASC 842, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the condensed consolidated balance sheet. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. The ROU asset is amortized over the lease term. Variable lease expenses, if any, are recorded when incurred. In calculating the ROU asset and related lease liability, the Company elected to combine lease and non-lease components. The Company excluded short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. Refer to Note 5 for the additional disclosures required by ASC 842.
Cryptocurrency Mining Cost of Revenue	Cryptocurrency Mining Cost of Revenue Cost of revenue - cryptocurrency mining consists primarily of natural gas, emissions, payroll and benefits and other direct production costs associated with the megawatts generated for the digital mining operation. Cost of revenue – cryptocurrency mining does not include depreciation and amortization.
Power and Capacity Cost of Revenue	Power and Capacity Cost of Revenue Cost of revenue - power and capacity consists primarily of natural gas, emissions, payroll and benefits and other direct production costs associated with the megawatts generated for the power produced by Greenidge and sold to the grid. Cost of revenue – power and capacity does not include depreciation and amortization.
Selling, General, and Administrative Expenses	Selling, General, and Administrative Expenses Selling, general and administrative expenses consist primarily of administrative payroll and benefits, business development costs, professional fees, and insurance.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for share-based payment awards exchanged for services at the estimated grant date fair value of the award. Stock options issued under the Company’s equity incentive plans are granted with an exercise price equal to no less than the market price of the Company’s stock at the date of grant and expire up to ten years from the date of the grants. These options generally vest on the grant date or over a three year period.
Income Taxes	Income Taxes Prior to the formation of Greenidge on January 27, 2021, the Company was treated as a partnership for federal and state income tax purposes. Pursuant to this election, the profit or loss of the Company is reported in the individual income tax returns of the members. Therefore, no provision for Federal or State taxes has been made for the year ended December 31, 2020. Subsequent to the conversion of GGH to Greenidge, the Company calculates the provision for income taxes in accordance with ASC 740, Income Taxes, (“ASC 740”). The current provision for income taxes represents actual or estimated amounts payable or refundable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. A valuation allowance may be provided to the extent management deems it is more likely than not that deferred tax assets will not be realized. The ultimate realization of net deferred tax assets is dependent upon the generation of future taxable income, in the appropriate taxing jurisdictions, during the periods in which temporary differences, net operating losses and tax credits become realizable. Management believes that it is more likely than not that the Company will realize the benefits of these temporary differences and operating loss and tax credit carryforwards, net of valuation allowances. The Company recognizes and measures tax positions taken or expected to be taken in its tax return based on their technical merit and assesses the likelihood that the positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. Interest and penalties on tax liabilities, if any, would be recorded as incurred in interest expense and other expenses, respectively.
Earnings Per Share	Earnings Per Share Basic net income per common share attributable to common shareholders is calculated by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share attributable to common shareholders is calculated by dividing net income attributable to common shareholders by the diluted weighted average number of common shares outstanding for the period. Basic and diluted income per common share is not provided for the three and six months ended June 30, 2020 as the Company was organized as an LLC during that period. The Company used the weighted average method in determining earnings per share in consideration of the conversion of participating securities to common shares due to the reorganization in January 2021.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles. in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. As an emerging growth company, the Company has elected to adopt this pronouncement following the effective date for private companies beginning with periods beginning after December 15, 2021. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures. Any new accounting standards, not disclosed above, that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.
Recent Accounting Pronouncements, Adopted	Recent Accounting Pronouncements, Adopted In February 2016, the FASB issued Accounting Standards Update ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms greater than 12 months and also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. Subsequent to the issuance of Topic 842, the FASB clarified the guidance through several ASUs; hereinafter the collection of lease guidance is referred to as “ASC 842”. On January 1, 2021, the Company adopted ASC 842. The Company had no leasing arrangements at the beginning of the period of adoption. As a result, no cumulative impact of adopting ASC 842 was recorded. The Company also elected to exclude leases with a term of 12 months or less in the recognized ROU assets and lease liabilities, when the likelihood of renewal is not probable. Refer to Note 5 for additional disclosures required by ASC 842. The Company determines if an arrangement is a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.
