NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Additionally, since there are no differences between net income and comprehensive income, all references to comprehensive income have been excluded from the consolidated financial statements.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash	Cash and cash equivalents consist of short-term, highly liquid investments with original maturities of three months or less. The Company maintains its cash in non-interest bearing accounts that are insured by the Federal Deposit Insurance Company up to $250,000. The Company’s deposits may, from time to time, exceed the $250,000 limit; however, management believes that there is no unusual risk present, as the Company places its cash with financial institutions which management considers being of high quality.
Digital Currencies	Digital currencies are included in current assets in the reported balance sheets and are considered an intangible asset with an indefinite useful life. Digital currencies are recorded at cost less any impairment. Currently Bitcoin constitutes the only cryptocurrency the Company mines or holds in material amounts. Cryptocurrencies held are accounted for as intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life 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. Impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the cryptocurrency at the time its fair value is being measured. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. However, in most cases the Company’s qualitative assessment indicates impairment when the quoted price of the cryptocurrency subsequently falls below its carrying amount and we are required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted.
Accounts Receivable	Accounts receivable are stated at the amount management expects to collect from balances outstanding at year end. An allowance for doubtful accounts is provided when necessary and is based upon management’s evaluation of outstanding accounts receivable at year end. The potential risk is limited to the amount recorded in the financial statements.
Inventory	Waste coal, fuel oil and limestone are valued at the lower of average cost or net realizable value and includes all related transportation and handling costs. The Company performs periodic assessments to determine the existence of obsolete, slow-moving, and unusable inventory and records necessary provisions to reduce such inventories to net realizable value.
Derivative Contracts	In accordance with guidance on accounting for derivative instruments and hedging activities all derivatives should be recognized at fair value. Derivatives or any portion thereof, that are not designated as, and effective as, hedges must be adjusted to fair value through earnings. Derivative contracts are classified as either assets or liabilities on the accompanying combined balance sheets. Certain contracts that require physical delivery may qualify for and be designated as normal purchases/normal sales. Such contracts are accounted for on an accrual basis. The Company uses derivative instruments to mitigate its exposure to various energy commodity market risks. The Company does not enter into any derivative contracts or similar arrangements for speculative or trading purposes. The Company will, at times, sell its forward unhedged electricity capacity to stabilize its future operating margins. As of December 31, 2021 and December 31, 2020, there are no open energy commodity derivatives outstanding. The Company also uses derivative instruments to mitigate the risks of Bitcoin market pricing volatility. The Company entered into a variable prepaid forward sale contract that mitigates Bitcoin market pricing volatility risks between a low and high collar of Bitcoin market prices during the contract term. This contract settles in September 2022. The contract meets the definition of a derivative transaction pursuant to guidance under ASC 815 and is considered a compound derivative instrument which is required to be presented at fair value subject to remeasurement each reporting period. The changes in fair value are recorded as changes in fair value of forward sale derivative as part of earnings.
Fair Value Measurements	The Company measures at fair value certain of its financial and non-financial assets and liabilities by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are: Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities; Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data; and Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
Property, Equipment and Cryptocurrency Machines	Property and equipment are recorded at cost. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance and repairs are charged to expense as incurred. The Company records all assets associated with the cryptocurrency mining operations at cost. These assets are comprised of storage trailers and the related electrical components. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. Depreciation is provided over the remaining estimated useful lives (“EUL”) of the related assets using the straight-line method. The Company’s depreciation is based on its Facility being considered a single property unit. Certain components of the Facility may require replacement or overhaul several times over its estimated life. Costs associated with overhauls are recorded as an expense in the period incurred. However, in instances where a replacement of a Facility component is significant and the Company can reasonably estimate the original cost of the component being replaced, the Company will write-off the replaced component and capitalize the cost of the replacement. The component will be depreciated over the lesser of the EUL of the component or the remaining useful life of the Facility. The Company reviews the carrying value of property and equipment for impairment whenever events and circumstances indicate that the carrying value of property and equipment may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of property and equipment. The factors considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the property and equipment is used, and the effects of obsolescence, demand, competition, and other economic factors. Management has assessed the basis of depreciation of the Company’s cryptocurrency machines used to verify digital currency transactions and generate digital currencies and believes they should be depreciated over a two-year period. The rate at which the Company generates digital assets and, therefore, consumes the economic benefits of its transaction verification servers, is influenced by a number of factors including the following: 1.The complexity of the transaction verification process which is driven by the algorithms contained within the Bitcoin open source software; 2.The general availability of appropriate computer processing capacity on a global basis (commonly referred to in the industry as hashing capacity which is measured in petahash units); and 3.Technological obsolescence reflecting rapid development in the transaction verification server industry such that more recently developed hardware is more economically efficient to run in terms of digital assets generated as a function of operating costs, primarily power costs, (i.e., the speed of hardware evolution in the industry is such that later hardware models generally have faster processing capacity combined with lower operating costs and a lower cost of purchase). The Company operates in an emerging industry for which limited data is available to make estimates of the useful economic lives of specialized equipment. Management has determined that two years best reflects the current expected useful life of transaction verification servers. This assessment takes into consideration the availability of historical data and management’s expectations regarding the direction of the industry including potential changes in technology. Management will review this estimate annually and will revise such estimate as and when data becomes available. To the extent that any of the assumptions underlying management’s estimate of useful life of its transaction verification servers are subject to revision in a future reporting period either as a result of changes in circumstances or through the availability of greater quantities of data then the estimated useful life could change and have a prospective impact on depreciation expense and the carrying amounts of these assets.
Asset Retirement Obligations	Asset retirement obligations, including those conditioned on future events, are recorded at fair value in the period in which they are incurred, if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset in the same period. In each subsequent period, the liability is accreted to its present value and the capitalized cost is depreciated over the EUL of the long-lived asset. If the asset retirement obligation is settled for other than the carrying amount of the liability, the Company recognizes a gain or loss on settlement. The Company’s asset retirement obligation represents the cost the Company would incur to perform environmental clean-up or dismantle certain portions of the Facility.
Impairment of Long-Lived Assets	In conjunction with ASC 360 - Property, Plant and Equipment, the Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. A long-lived asset or asset group that is held and used must be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived asset or asset group might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.
Revenue Recognition	The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principle of this revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle: 1.Step 1: Identify the contract with the customer 2.Step 2: Identify the performance obligations in the contract 3.Step 3: Determine the transaction price 4.Step 4: Allocate the transaction price to the performance obligations in the contract 5.Step 5: Recognize revenue when the Company satisfies a performance obligation In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract). If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct. The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following: •Variable consideration •Constraining estimates of variable consideration •The existence of a significant financing component in the contract •Noncash consideration •Consideration payable to a customer Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate. There is currently no specific definitive guidance under GAAP or alternative accounting framework for the accounting for cryptocurrencies recognized as revenue or held, and management has exercised significant judgment in determining the appropriate accounting treatment. In the event authoritative guidance is enacted by the Financial Accounting Standards Board (the "FASB"), the Company may be required to change its policies, which could have an effect on the Company’s consolidated financial position and results from operations. Fair value of the digital asset award received is determined using the quoted price of the related cryptocurrency at the time of receipt. The Company’s policies with respect to its revenue streams are detailed below. Energy Revenue The Company operates as a market participant through PJM Interconnection, a Regional Transmission Organization (“RTO”) that coordinates the movement of wholesale electricity. The Company sells energy in the wholesale generation market in the PJM RTO. Energy revenues are delivered as a series of distinct units that are substantially the same and that have the same pattern of transfer to the customer over time and are therefore accounted for as a distinct performance obligation. The transaction price is based on pricing published in the day ahead market which constitute the stand-alone selling price. Energy revenue is recognized over time as energy volumes are generated and delivered to the RTO (which is contemporaneous with generation), using the output method for measuring progress of satisfaction of the performance obligation. The Company applies the invoice practical expedient in recognizing energy revenue. Under the invoice practical expedient, energy revenue is recognized based on the invoiced amount which is considered equal to the value provided to the customer for the Company’s performance obligation completed to date. Reactive energy power is provided to maintain a continuous voltage level. Revenue from reactive power is recognized ratably over time as the Company stands ready to provide it if called upon by the PJM RTO. Capacity Revenue The Company provides capacity to a customer through participation in capacity auctions held by the PJM RTO. Capacity revenues are a series of distinct performance obligations that are substantially the same and that have the same pattern of transfer to the customer over time and are therefore accounted for as a distinct performance obligation. The transaction price for capacity is market-based and constitutes the stand-alone selling price. As capacity represents the Company’s stand-ready obligation, capacity revenue is recognized as the performance obligation is satisfied ratably over time, on a monthly basis, since the Company stands ready equally throughout the period to deliver power to the PJM RTO if called upon. The Company applies the invoice practical expedient in recognizing capacity revenue. Under the invoice practical expedient, capacity revenue is recognized based on the invoiced amount which is considered equal to the value provided to the customer for the Company’s performance obligation completed to date. Penalties may be assessed by the PJM RTO against generation facilities if the facility is not available during the capacity period. The penalties assessed by the PJM RTO, if any, are recorded as a reduction to capacity revenue when incurred. Cryptocurrency Hosting The Company has entered into customer hosting contracts whereby the Company provides electrical power to cryptocurrency mining customers, and the customers pay a stated amount per megawatt-hour (“MWh”) (“Contract Capacity”). This amount is paid monthly in advance. Amounts used in excess of the Contract Capacity are billed based upon calculated formulas as contained in the contracts. If any shortfalls occur to due to outages, make-whole payment provisions contained in the contracts are used to offset the billings to the customer which prevented them from cryptocurrency mining. Advanced payments and customer deposits are reflected as contract liabilities. Cryptocurrency Mining The Company has entered into digital asset mining pools by executing contracts, as amended from time to time, with the mining pool operators to provide computing power to the mining pool. The contracts are terminable at any time by either party and the Company’s enforceable right to compensation only begins when the Company provides computing power to the mining pool operator. In exchange for providing computing power, the Company is entitled to a fractional share of the fixed cryptocurrency award the mining pool operator receives (less digital asset transaction fees to the mining pool operator which are recorded as a component of cost of revenues), for successfully adding a block to the blockchain. The terms of the agreement provide that neither party can dispute settlement terms after thirty-five days following settlement. The Company’s fractional share is based on the proportion of computing power the Company contributed to the mining pool operator to the total computing power contributed by all mining pool participants in solving the current algorithm. Providing computing power in digital asset transaction verification services is an output of the Company’s ordinary activities. The provision of providing such computing power is the only performance obligation in the Company’s contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block (by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue is recognized. There is no significant financing component in these transactions. Fair value of the cryptocurrency award received is determined using the quoted price of the related cryptocurrency at the time of receipt. There is currently no specific definitive guidance under GAAP or alternative accounting framework for the accounting for cryptocurrencies recognized as revenue or held, and management has exercised significant judgment in determining the appropriate accounting treatment. In the event authoritative guidance is enacted by the FASB, the Company may be required to change its policies, which could have an effect on the Company’s consolidated financial position and results from operations.
Waste Coal Credits	Waste coal credits are issued by the Commonwealth of Pennsylvania. Facilities that generate electricity by using coal refuse for power generation, control acid gases for emission control, and use the ash produced to reclaim mining-affected sites are eligible for such credits. Income related to these credits is recorded upon cash receipt and within other income.Renewable Energy Credits (“RECs”)The Company uses coal refuse, which is classified as a Tier II Alternative Energy Source under Pennsylvania law, to produce energy to sell to the open market (“the grid”). A third party acts as the benefactor, on behalf of the Company, in the open market and is invoiced as RECs are realized. These credits are recognized as a contra-expense to offset the fuel costs to produce this refuse.
Waste Ash Sales	The Company sells fly ash and scrubber material collected. This is a by-product from their coal refuse reclamation used as fuel. Buyer pays 50% of a resale price, up to 50,000 tons, unless agreed to in writing to exceed this weight limit, Income related to these sales are recorded within other income.
Stock Based Compensation	For equity-classified awards, compensation expense is recognized over the requisite service period based on the computed fair value on the grant date of the award. Equity classified awards include the issuance of stock options and restricted stock units (“RSUs”).
Notes Payable	The Company records notes payable net of any discounts or premiums. Discounts and premiums are amortized as interest expense or income over the life of the note in such a way as to result in a constant rate of interest when applied to the amount outstanding at the beginning of any given period.
Warrant Liabilities	The Company records warrant liabilities at their fair value as of the balance sheet date, and recognizes changes in the balances, over the comparative periods of either the issuance date or the last reporting date, as part of changes in fair value of warrant liabilities expense. At the issuance date, each series of warrants were convertible and redeemable to preferred stock. As of October 22, 2021 (the closing date of the IPO (as defined below)), all preferred stock converted to common stock one for one. As such, the warrant liability was revalued and reclassified to equity due to the equity offering and conversion as common shares.
Segment Information	Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”). The role of the CODM is to make decisions about allocating resources and assessing performance. The Company’s operations are based on its Energy Operations and Cryptocurrency Operations and thus the Company concluded its business operates in two operating segments. The CODM reviews financial information presented on each of these two operating segments for purposes of allocating resources and evaluating financial performance. The Company’s chief executive officer has been identified as its CODM. The Company's two operating segments are also its reportable segments: Energy Operations and Cryptocurrency Operations.
Common Stock - Class V	The Company accounts for the 56.1% interest represented by the Class V common stock outside of permanent equity as a result of certain redemption rights held by the holders that are outside the control of the Company. As such, the Company adjusts the Common Stock - Class V to its maximum redemption amount at the balance sheet date, if higher than the carrying amount. The redemption amount is based on a third-party valuation methodology of the Company’s Class A common stock at the end of the reporting period. Changes in the redemption value are recognized immediately as they occur, as if the end of the reporting period was also the redemption date for the instrument, with an offsetting entry to accumulated deficit. For each share of Class V common stock outstanding, there is a corresponding outstanding Class A common unit of Stronghold LLC. The redemption of any share of Class V common stock would be accompanied by a concurrent redemption of the corresponding Class A common unit of Stronghold LLC, such that both the share of Class V common stock and the corresponding Class A common unit of Stronghold LLC are redeemed as a combined unit in exchange for either a single share of Class A common stock or cash of equivalent value based on the fair value of the Class A common stock at the time of the redemption. For accounting purposes, the value of the Class A common units of Stronghold LLC is attributed to the corresponding shares of Class V common stock on the December 31, 2021 balance sheet.
Loss per Share	Basic net (loss) income per share (“EPS”) of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding or shares subject to exercise for a nominal value during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.
Income Taxes	Reorganization Upon completion of the Reorganization, the Company is organized as an “Up-C” structure in which substantially all of the assets and business of the consolidated Company are held by Stronghold Inc. through its subsidiaries, and the Company’s direct assets largely consist of cash and investments in subsidiaries. For income tax purposes, the portion of the Company’s earnings allocable to Stronghold Inc. is subject to corporate income tax rates at the federal and state levels. Therefore, the income taxes recorded prior to the Reorganization are not representative of the income taxes after the Reorganization. The Company accounts for income taxes under the asset and liability method, in which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. A valuation allowance is required to the extent any deferred tax assets may not be realizable. Based on the Company’s evaluation and application of ASC Topic 740, Income Taxes (“ASC 740”), the Company has determined that the utilization of the deferred tax assets is not more likely than not, and therefore the Company has recorded a valuation allowance against the net deferred tax assets of the Company. Factors contributing to this assessment include the Company’s cumulative and current losses, as well as the evaluation of other sources of income as outlined in ASC 740. The Company continues to evaluate the likelihood of the utilization of deferred tax assets, and while the valuation allowance remains in place, we expect to record no deferred income tax expense or benefit. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. Based on the Company's evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company's consolidated financial statements. Although the Company has not yet filed a corporate tax return, the basis of tax positions applied to our tax provisions substantially comply with applicable federal and state regulations. We acknowledge the respective taxing authorities may take contrary positions based on their interpretation of the law. A tax position successfully challenged by a taxing authority could result in an adjustment to our provision or benefit for income taxes in the period in which a final determination is made. As of December 31, 2021, the Company's tax years ended December 31, 2018 through 2021 are open for potential examination by taxing authorities. Certain of Stronghold Inc.’s subsidiaries are structured as flow-through entities; and therefore the taxable income or loss of such subsidiaries is included in the income tax returns of the partners, including Stronghold Inc. Application of ASC 740 to these entities results in no recognition of federal or state income taxes at the entity level. The portion of such subsidiaries' activities that are allocable to the Company will increase the Company’s taxable income or loss and be accounted for under ASC 740 at the Company. Prior to the Reorganization Scrubgrass and Stronghold LLC were structured as a limited partnership and limited liability company, respectively; therefore the taxable income or loss of the Company is included in the income tax returns of the individual partners. Accordingly, no recognition has been given to federal or state income taxes in the accompanying financial statements. Two of Scrubgrass' subsidiaries, Clearfield and Leechburg, are corporations for federal and state income tax purposes. Income taxes attributable to Clearfield and Leechburg are provided based on the asset and liability method of accounting pursuant to the Income Taxes Topic of FASB ASC 740, both prior to and subsequent to the Reorganization. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all, of the deferred tax asset will not be realized. Clearfield and Leechburg have not recorded any temporary differences resulting in either a deferred tax asset or liability as of December 31, 2021, or 2020.
Recently Issued Accounting Standards	Recently Issued Accounting StandardsIn February 2016, FASB issued ASU 2016-02, Leases (“Topic 842”), which supersedes ASC Topic 840, Leases. Topic 842 requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. Topic 842 will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In November 2020, FASB deferred the effective date for implementation of Topic 842 by one year and, in June 2020, FASB deferred the effective date by an additional year. Topic 842 is effective for the Company on January 1, 2022. The Company is currently in the process of developing its new accounting policies and determining the potential aggregate impact that the adoption of Topic 842 will have on its financial statements. The Company does not believe the adoption of this standard will have a material impact on the consolidated financial statements.

NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2021

Additionally, since there are no differences between net income and comprehensive income, all references to comprehensive income have been excluded from the consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash

Cash and cash equivalents consist of short-term, highly liquid investments with original maturities of three months or less. The Company maintains its cash in non-interest bearing accounts that are insured by the Federal Deposit Insurance Company up to $250,000. The Company’s deposits may, from time to time, exceed the $250,000 limit; however, management believes that there is no unusual risk present, as the Company places its cash with financial institutions which management considers being of high quality.

Digital Currencies

Digital currencies are included in current assets in the reported balance sheets and are considered an intangible asset with an indefinite useful life. Digital currencies are recorded at cost less any impairment. Currently Bitcoin constitutes the only cryptocurrency the Company mines or holds in material amounts.

Cryptocurrencies held are accounted for as intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life 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. Impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the cryptocurrency at the time its fair value is being measured. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. However, in most cases the Company’s qualitative assessment indicates impairment when the quoted price of the cryptocurrency subsequently falls below its carrying amount and we are required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from balances outstanding at year end. An allowance for doubtful accounts is provided when necessary and is based upon management’s evaluation of outstanding accounts receivable at year end. The potential risk is limited to the amount recorded in the financial statements.

Inventory

The Company performs periodic assessments to determine the existence of obsolete, slow-moving, and unusable inventory and records necessary provisions to reduce such inventories to net realizable value.

Derivative Contracts

In accordance with guidance on accounting for derivative instruments and hedging activities all derivatives should be recognized at fair value. Derivatives or any portion thereof, that are not designated as, and effective as, hedges must be adjusted to fair value through earnings. Derivative contracts are classified as either assets or liabilities on the accompanying combined balance sheets. Certain contracts that require physical delivery may qualify for and be designated as normal purchases/normal sales. Such contracts are accounted for on an accrual basis.

The Company uses derivative instruments to mitigate its exposure to various energy commodity market risks. The Company does not enter into any derivative contracts or similar arrangements for speculative or trading purposes. The Company will, at times, sell its forward unhedged electricity capacity to stabilize its future operating margins. As of December 31, 2021 and December 31, 2020, there are no open energy commodity derivatives outstanding.

The Company also uses derivative instruments to mitigate the risks of Bitcoin market pricing volatility. The Company entered into a variable prepaid forward sale contract that mitigates Bitcoin market pricing volatility risks between a low and high collar of Bitcoin market prices during the contract term. This contract settles in September 2022. The contract meets the definition of a derivative transaction pursuant to guidance under ASC 815 and is considered a compound derivative

instrument which is required to be presented at fair value subject to remeasurement each reporting period. The changes in fair value are recorded as changes in fair value of forward sale derivative as part of earnings.

Fair Value Measurements

The Company measures at fair value certain of its financial and non-financial assets and liabilities by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are:

Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities;

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data; and

Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Property, Equipment and Cryptocurrency Machines

Property and equipment are recorded at cost. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance and repairs are charged to expense as incurred. The Company records all assets associated with the cryptocurrency mining operations at cost. These assets are comprised of storage trailers and the related electrical components. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. Depreciation is provided over the remaining estimated useful lives (“EUL”) of the related assets using the straight-line method.

The Company’s depreciation is based on its Facility being considered a single property unit. Certain components of the Facility may require replacement or overhaul several times over its estimated life. Costs associated with overhauls are recorded as an expense in the period incurred. However, in instances where a replacement of a Facility component is significant and the Company can reasonably estimate the original cost of the component being replaced, the Company will write-off the replaced component and capitalize the cost of the replacement. The component will be depreciated over the lesser of the EUL of the component or the remaining useful life of the Facility.

The Company reviews the carrying value of property and equipment for impairment whenever events and circumstances indicate that the carrying value of property and equipment may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of property and equipment. The factors considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the property and equipment is used, and the effects of obsolescence, demand, competition, and other economic factors.

Management has assessed the basis of depreciation of the Company’s cryptocurrency machines used to verify digital currency transactions and generate digital currencies and believes they should be depreciated over a two-year period. The rate at which the Company generates digital assets and, therefore, consumes the economic benefits of its transaction verification servers, is influenced by a number of factors including the following:

1.The complexity of the transaction verification process which is driven by the algorithms contained within the Bitcoin open source software;

2.The general availability of appropriate computer processing capacity on a global basis (commonly referred to in the industry as hashing capacity which is measured in petahash units); and

3.Technological obsolescence reflecting rapid development in the transaction verification server industry such that more recently developed hardware is more economically efficient to run in terms of digital assets generated as a function of operating costs, primarily power costs, (i.e., the speed of hardware evolution in the industry is such that later hardware models generally have faster processing capacity combined with lower operating costs and a lower cost of purchase).

The Company operates in an emerging industry for which limited data is available to make estimates of the useful economic lives of specialized equipment. Management has determined that two years best reflects the current expected useful life of transaction verification servers. This assessment takes into consideration the availability of historical data and management’s expectations regarding the direction of the industry including potential changes in technology. Management will review this estimate annually and will revise such estimate as and when data becomes available.

To the extent that any of the assumptions underlying management’s estimate of useful life of its transaction verification servers are subject to revision in a future reporting period either as a result of changes in circumstances or through the availability of greater quantities of data then the estimated useful life could change and have a prospective impact on depreciation expense and the carrying amounts of these assets.

Asset Retirement Obligations

Asset retirement obligations, including those conditioned on future events, are recorded at fair value in the period in which they are incurred, if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset in the same period. In each subsequent period, the liability is accreted to its present value and the capitalized cost is depreciated over the EUL of the long-lived asset. If the asset retirement obligation is settled for other than the carrying amount of the liability, the Company recognizes a gain or loss on settlement. The Company’s asset retirement obligation represents the cost the Company would incur to perform environmental clean-up or dismantle certain portions of the Facility.

Impairment of Long-Lived Assets

In conjunction with ASC 360 - Property, Plant and Equipment, the Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. A long-lived asset or asset group that is held and used must be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived asset or asset group might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Revenue Recognition

The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principle of this revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

1.Step 1: Identify the contract with the customer

2.Step 2: Identify the performance obligations in the contract

3.Step 3: Determine the transaction price

4.Step 4: Allocate the transaction price to the performance obligations in the contract

5.Step 5: Recognize revenue when the Company satisfies a performance obligation

In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both.

When determining the transaction price, an entity must consider the effects of all of the following:

•Variable consideration

•Constraining estimates of variable consideration

•The existence of a significant financing component in the contract

•Noncash consideration

•Consideration payable to a customer

Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate.

There is currently no specific definitive guidance under GAAP or alternative accounting framework for the accounting for cryptocurrencies recognized as revenue or held, and management has exercised significant judgment in determining the appropriate accounting treatment. In the event authoritative guidance is enacted by the Financial Accounting Standards Board (the "FASB"), the Company may be required to change its policies, which could have an effect on the Company’s consolidated financial position and results from operations.

Fair value of the digital asset award received is determined using the quoted price of the related cryptocurrency at the time of receipt.

The Company’s policies with respect to its revenue streams are detailed below.

Energy Revenue

The Company operates as a market participant through PJM Interconnection, a Regional Transmission Organization (“RTO”) that coordinates the movement of wholesale electricity. The Company sells energy in the wholesale generation market in the PJM RTO. Energy revenues are delivered as a series of distinct units that are substantially the same and that have the same pattern of transfer to the customer over time and are therefore accounted for as a distinct performance obligation. The transaction price is based on pricing published in the day ahead market which constitute the stand-alone selling price.

Energy revenue is recognized over time as energy volumes are generated and delivered to the RTO (which is contemporaneous with generation), using the output method for measuring progress of satisfaction of the performance obligation. The Company applies the invoice practical expedient in recognizing energy revenue. Under the invoice practical expedient, energy revenue is recognized based on the invoiced amount which is considered equal to the value provided to the customer for the Company’s performance obligation completed to date.

Reactive energy power is provided to maintain a continuous voltage level. Revenue from reactive power is recognized ratably over time as the Company stands ready to provide it if called upon by the PJM RTO.

Capacity Revenue

The Company provides capacity to a customer through participation in capacity auctions held by the PJM RTO. Capacity revenues are a series of distinct performance obligations that are substantially the same and that have the same pattern of transfer to the customer over time and are therefore accounted for as a distinct performance obligation. The transaction price for capacity is market-based and constitutes the stand-alone selling price. As capacity represents the Company’s stand-ready obligation, capacity revenue is recognized as the performance obligation is satisfied ratably over time, on a monthly basis, since the Company stands ready equally throughout the period to deliver power to the PJM RTO if called upon. The Company applies the invoice practical expedient in recognizing capacity revenue. Under the invoice practical expedient, capacity revenue is recognized based on the invoiced amount which is considered equal to the value provided to the customer for the Company’s performance obligation completed to date. Penalties may be assessed by the PJM RTO against generation facilities if the facility is not available during the capacity period. The penalties assessed by the PJM RTO, if any, are recorded as a reduction to capacity revenue when incurred.

Cryptocurrency Hosting

The Company has entered into customer hosting contracts whereby the Company provides electrical power to cryptocurrency mining customers, and the customers pay a stated amount per megawatt-hour (“MWh”) (“Contract Capacity”). This amount is paid monthly in advance. Amounts used in excess of the Contract Capacity are billed based upon calculated formulas as contained in the contracts. If any shortfalls occur to due to outages, make-whole payment provisions contained in the contracts are used to offset the billings to the customer which prevented them from cryptocurrency mining. Advanced payments and customer deposits are reflected as contract liabilities.

Cryptocurrency Mining

The Company has entered into digital asset mining pools by executing contracts, as amended from time to time, with the mining pool operators to provide computing power to the mining pool. The contracts are terminable at any time by either party and the Company’s enforceable right to compensation only begins when the Company provides computing power to the mining pool operator. In exchange for providing computing power, the Company is entitled to a fractional share of the fixed cryptocurrency award the mining pool operator receives (less digital asset transaction fees to the mining pool operator which are recorded as a component of cost of revenues), for successfully adding a block to the blockchain. The terms of the agreement provide that neither party can dispute settlement terms after thirty-five days following settlement. The Company’s fractional share is based on the proportion of computing power the Company contributed to the mining pool operator to the total computing power contributed by all mining pool participants in solving the current algorithm.

Providing computing power in digital asset transaction verification services is an output of the Company’s ordinary activities. The provision of providing such computing power is the only performance obligation in the Company’s contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block (by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue is recognized. There is no significant financing component in these transactions.

Fair value of the cryptocurrency award received is determined using the quoted price of the related cryptocurrency at the time of receipt. There is currently no specific definitive guidance under GAAP or alternative accounting framework for the accounting for cryptocurrencies recognized as revenue or held, and management has exercised significant judgment in determining the appropriate accounting treatment. In the event authoritative guidance is enacted by the FASB, the Company may be required to change its policies, which could have an effect on the Company’s consolidated financial position and results from operations.

Waste Coal Credits

Waste coal credits are issued by the Commonwealth of Pennsylvania. Facilities that generate electricity by using coal refuse for power generation, control acid gases for emission control, and use the ash produced to reclaim mining-affected sites are eligible for such credits. Income related to these credits is recorded upon cash receipt and within other income.Renewable Energy Credits (“RECs”)The Company uses coal refuse, which is classified as a Tier II Alternative Energy Source under Pennsylvania law, to produce energy to sell to the open market (“the grid”). A third party acts as the benefactor, on behalf of the Company, in the open market and is invoiced as RECs are realized. These credits are recognized as a contra-expense to offset the fuel costs to produce this refuse.

Waste Ash Sales

The Company sells fly ash and scrubber material collected. This is a by-product from their coal refuse reclamation used as fuel. Buyer pays 50% of a resale price, up to 50,000 tons, unless agreed to in writing to exceed this weight limit, Income related to these sales are recorded within other income.

Stock Based Compensation

For equity-classified awards, compensation expense is recognized over the requisite service period based on the computed fair value on the grant date of the award. Equity classified awards include the issuance of stock options and restricted stock units (“RSUs”).

Notes Payable

The Company records notes payable net of any discounts or premiums. Discounts and premiums are amortized as interest expense or income over the life of the note in such a way as to result in a constant rate of interest when applied to the amount outstanding at the beginning of any given period.

Warrant Liabilities

The Company records warrant liabilities at their fair value as of the balance sheet date, and recognizes changes in the balances, over the comparative periods of either the issuance date or the last reporting date, as part of changes in fair value of warrant liabilities expense. At the issuance date, each series of warrants were convertible and redeemable to preferred stock. As of October 22, 2021 (the closing date of the IPO (as defined below)), all preferred stock converted to common stock one for one. As such, the warrant liability was revalued and reclassified to equity due to the equity offering and conversion as common shares.

Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”). The role of the CODM is to make decisions about allocating resources and assessing performance. The Company’s operations are based on its Energy Operations and Cryptocurrency Operations and thus the Company concluded its business operates in two operating segments. The CODM reviews financial information presented on each of these two operating segments for purposes of allocating resources and evaluating financial performance. The Company’s chief executive officer has been identified as its CODM. The Company's two operating segments are also its reportable segments: Energy Operations and Cryptocurrency Operations.

Common Stock - Class V

The Company accounts for the 56.1% interest represented by the Class V common stock outside of permanent equity as a result of certain redemption rights held by the holders that are outside the control of the Company. As such, the Company adjusts the Common Stock - Class V to its maximum redemption amount at the balance sheet date, if higher than the carrying amount. The redemption amount is based on a third-party valuation methodology of the Company’s Class A common stock at the end of the reporting period. Changes in the redemption value are recognized immediately as they occur, as if the end of the reporting period was also the redemption date for the instrument, with an offsetting entry to accumulated deficit.

For each share of Class V common stock outstanding, there is a corresponding outstanding Class A common unit of Stronghold LLC. The redemption of any share of Class V common stock would be accompanied by a concurrent redemption of the corresponding Class A common unit of Stronghold LLC, such that both the share of Class V common stock and the corresponding Class A common unit of Stronghold LLC are redeemed as a combined unit in exchange for

either a single share of Class A common stock or cash of equivalent value based on the fair value of the Class A common stock at the time of the redemption. For accounting purposes, the value of the Class A common units of Stronghold LLC is attributed to the corresponding shares of Class V common stock on the December 31, 2021 balance sheet.

Loss per Share

Basic net (loss) income per share (“EPS”) of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding or shares subject to exercise for a nominal value during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.

Income Taxes

Reorganization

Upon completion of the Reorganization, the Company is organized as an “Up-C” structure in which substantially all of the assets and business of the consolidated Company are held by Stronghold Inc. through its subsidiaries, and the Company’s direct assets largely consist of cash and investments in subsidiaries. For income tax purposes, the portion of the Company’s earnings allocable to Stronghold Inc. is subject to corporate income tax rates at the federal and state levels. Therefore, the income taxes recorded prior to the Reorganization are not representative of the income taxes after the Reorganization.

The Company accounts for income taxes under the asset and liability method, in which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. A valuation allowance is required to the extent any deferred tax assets may not be realizable. Based on the Company’s evaluation and application of ASC Topic 740, Income Taxes (“ASC 740”), the Company has determined that the utilization of the deferred tax assets is not more likely than not, and therefore the Company has recorded a valuation allowance against the net deferred tax assets of the Company. Factors contributing to this assessment include the Company’s cumulative and current losses, as well as the evaluation of other sources of income as outlined in ASC 740. The Company continues to evaluate the likelihood of the utilization of deferred tax assets, and while the valuation allowance remains in place, we expect to record no deferred income tax expense or benefit.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. Based on the Company's evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company's consolidated financial statements. Although the Company has not yet filed a corporate tax return, the basis of tax positions applied to our tax provisions substantially comply with applicable federal and state regulations. We acknowledge the respective taxing authorities may take contrary positions based on their interpretation of the law. A tax position successfully challenged by a taxing authority could result in an adjustment to our provision or benefit for income taxes in the period in which a final determination is made. As of December 31, 2021, the Company's tax years ended December 31, 2018 through 2021 are open for potential examination by taxing authorities.

Certain of Stronghold Inc.’s subsidiaries are structured as flow-through entities; and therefore the taxable income or loss of such subsidiaries is included in the income tax returns of the partners, including Stronghold Inc. Application of ASC 740 to these entities results in no recognition of federal or state income taxes at the entity level. The portion of such subsidiaries' activities that are allocable to the Company will increase the Company’s taxable income or loss and be accounted for under ASC 740 at the Company.

Prior to the Reorganization

Scrubgrass and Stronghold LLC were structured as a limited partnership and limited liability company, respectively; therefore the taxable income or loss of the Company is included in the income tax returns of the individual partners. Accordingly, no recognition has been given to federal or state income taxes in the accompanying financial statements.

Two of Scrubgrass' subsidiaries, Clearfield and Leechburg, are corporations for federal and state income tax purposes. Income taxes attributable to Clearfield and Leechburg are provided based on the asset and liability method of accounting pursuant to the Income Taxes Topic of FASB ASC 740, both prior to and subsequent to the Reorganization. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all, of the deferred tax asset will not be realized. Clearfield and Leechburg have not recorded any temporary differences resulting in either a deferred tax asset or liability as of December 31, 2021, or 2020.

Recently Issued Accounting Standards

Recently Issued Accounting StandardsIn February 2016, FASB issued ASU 2016-02, Leases (“Topic 842”), which supersedes ASC Topic 840, Leases. Topic 842 requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. Topic 842 will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In November 2020, FASB deferred the effective date for implementation of Topic 842 by one year and, in June 2020, FASB deferred the effective date by an additional year. Topic 842 is effective for the Company on January 1, 2022. The Company is currently in the process of developing its new accounting policies and determining the potential aggregate impact that the adoption of Topic 842 will have on its financial statements. The Company does not believe the adoption of this standard will have a material impact on the consolidated financial statements.
