Description of Organization, Business Operations and Basis of Presentation	Note 1 — Description of Organization and Business Operations Rice Acquisition Corp. (the “Company”) was incorporated in Delaware on September -owned As of December -operating The Company’s sponsor is Rice Acquisition Sponsor LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on October -allotment -Allotment Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 6,771,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) to the Sponsor and Atlas Point Energy Infrastructure Fund, LLC (“Atlas Point Fund”), at a price of $1.00 per Private Placement Warrant, generating gross proceeds to the Company of approximately $6.8 -economic Following the Initial Public Offering, the Public Stockholders (as defined below) will hold a direct economic equity ownership interest in Rice in the form of shares of Class A common stock, and an indirect ownership interest in Opco through Rice’s ownership of Class A Units of Opco. By contrast, the Initial Stockholders (as defined below) will own direct economic interests in Opco in the form of Class B Units and a corresponding non -economic Upon the closing of the Initial Public Offering and the Private Placement, approximately $237.3 -7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting discount held in Trust) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post -business The Company will provide the holders (the “Public Stockholders”) of the Company’s Public Shares with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. Unless otherwise stated herein, the term “Public Shares” includes the 2,500 -share The Amended and Restated Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Public Shares, without the prior consent of the Company. If the Company is unable to complete a Business Combination within 24 -share franchise and income taxes of the Company or Opco (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares and Class A Units of Opco (other than those held by Rice), which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Sponsor, Atlas Point Fund and the Company’s officers and directors (the “Initial Stockholders”) have agreed (i) that any Founder Shares and Sponsor Shares held by them will not be entitled to redemption rights, and they will waive any such redemption rights for any Public Shares held by them, in connection with the completion of the initial Business Combination, (ii) that any Founder Shares and Sponsor Shares held by them will not be entitled to redemption rights, and they will waive any such redemption rights for any Public Shares held by them, in connection with a stockholder vote to amend our amended and restated certificate of incorporation in a manner that would affect the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company have not consummated the initial Business Combination within the Combination Period, (iii) that any Founder Shares held by them are subject to forfeiture, and thus will not be entitled to liquidating distributions from the Trust Account, and they will waive any such rights to liquidating distributions for any Founder Shares, if the Company fails to complete the initial Business Combination within the Combination Period (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares and Sponsor Shares they hold if the Company fails to complete the initial Business Combination within the Combination Period), and (iv) in certain limited circumstances the Class B Units of Opco will have more limited rights to current or liquidating distributions from the Company. The underwriters agreed to waive their rights to the deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and subsequently liquidates and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares and Sponsor Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share or Class A Unit of Opco not held by Rice and (ii) the actual amount per Public Share or Class A Unit of Opco not held by Rice held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share or Class A Unit of Opco not held by Rice due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except for the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Basis of Presentation and Principles of Consolidation The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. The consolidated financial statements include the accounts of the Company and its majority -owned Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes -Oxley Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non -emerging This may make comparison of the Company’s Consolidated Financial Statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Liquidity and Capital Resources As of December The Company’s liquidity needs to date had been satisfied through the payment of $26,000 from the Sponsor to purchase the Founder Shares and Sponsor Shares (see Note 5), the loan under the Note of approximately $290,000 (see Note 5), and the net proceeds from the consummation of the Private Placement not held in the Trust Account. The Company repaid the Note in full on November Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

The financial statements and notes are prepared by the management of the Company, who are responsible for their integrity and objectivity. These unaudited interim financial statements reflect all adjustments which are, in the opinion of management, necessary to present fairly the results for the interim periods presented. These accounting policies conform to accounting principles generally accepted in the United States of America and have been consistently applied in the presentation of the financial statements.

The Company looks to source, build and manage projects for the entirety of an energy project’s lifecycle. Through June 30, 2021, the Company has been primarily engaged in the development of high BTU biogas facilities aimed at providing a renewable fuel source expected to power truck and bus fleets across the United States. The Company has entered into various landfill biogas right agreements with certain landfill owners for the construction and operation of biogas facilities. By partnering with landfill owners, the Company expects to capture and convert landfill gases to generate renewable natural gas. The Company commenced principal operations at its Big Run site in April 2021. The Company continues to incur significant expenditures for the design and development of several biogas facilities, most notable its Assai project located in the Scranton, PA metro area. The Company’s activities are subject to certain risks and uncertainties, including the ability to raise additional capital to complete the biogas facilities and to successfully market its renewable fuel solutions to transportation and other markets. During the year ended December 31, 2020, the Company purchased 100% of Big Run Power Producers, LLC, a biogas facility located in Ashland, Kentucky. This facility started the pilot stage of RNG production during April 2021, and the Company continues to bring additional wells on -line During the year ended December 31, 2020, the Company purchased 72.2% of Gulf Coast Environmental Systems, LLC (“GCES”). Located in Conroe, Texas, GCES is an original equipment manufacturer of air, water, and soil remediation pollution control systems. On April 7, 2021, the Company completed the acquisition of PEI Power LLC (“PEI”) and acquired 100% of the outstanding membership interests of PEI for cash consideration. PEI is a biogas fuel combustion power generating facility with a combined capacity of approximately 85 MW located in Archbald, PA. The consolidated financial statements of the Company include all wholly owned subsidiaries, as well as all variable interest entities that the Company determined it is the primary beneficiary. All intercompany balances and transactions have been eliminated. Basis of Presentation The financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Segment Reporting The Company reports segment information in three segments: renewable natural gas (“RNG”), renewable electricity generation (“REG”) and GCES. The Company currently manages RNG as its primary business operations, which is to construct and develop biogas facilities on landfill sites of for conversion to RNG. The Company’s REG started during 2021 with the acquisition of PEI Power, LLC and is typically sold under a market -based GCES was acquired by the Company in 2020 as a complementary operation to provide cost savings in association with the construction of its plants due to their specialization in manufacturing customized pollution control systems. While RNG is a customer of GCES, GCES also has external third -party Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as contingent assets and liabilities. The estimates and assumptions used in the accompanying financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statements. Noncontrolling Interest Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to the members’ equity holders of the Company. Noncontrolling interests are initially recorded at transaction price which is equal to their fair value, and the amount is subsequently adjusted for the proportionate share of earnings and other comprehensive income attributable to the noncontrolling interests and any dividends or distributions paid to the noncontrolling interests. Fair Value Measurements Fair value is the price at which an asset could be exchanged, or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or derived from such prices. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The framework for establishing fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. In accordance with ASC 820, Fair Value Measurement (“ASC 820”), the hierarchy discussed above requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy defines three levels of inputs that may be used to measure fair value, as discussed below. In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques taking into account the characteristics of the asset. In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability. The Company’s financial assets and liabilities are classified based on the lowest level of input that is significant for the fair value measurement. The Company reflects transfers between the three levels at the beginning of the reporting period in which the availability of observable inputs no longer justifies classification in the original level. There were no transfers between fair value hierarchy levels for the six months ended June 30, 2021 or the year ended December 31, 2020. As of the six months ended June 30, 2021 and year ended December 31, 2020, the fair value of other financial instruments including cash and cash equivalents, prepaid expenses, accounts payable, accrued and deferred expenses approximate the carrying values because of the short -term -term Fair Value on a Nonrecurring Basis Business Acquisitions For acquisitions that are determined to be the acquisition of a business, the Company records the identifiable assets acquired, liabilities assumed and noncontrolling interest, if applicable, at fair value at the date of acquisition on a nonrecurring basis. Fair value may be estimated using comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow method, estimated future cash flows are based on management’s expectations for the future and can include estimates of future biogas production, commodity prices, operating and development costs, and a risk -adjusted Asset Retirement Obligations The Company accounts for asset retirement obligations as required under ASC 410, Asset Retirement and Environmental Obligations, (“ASC 410”). ASC 410 requires the fair value of a liability for an asset retirement obligation be recognized in the period in which the legal obligation arises, with the associated discounted asset retirement costs being capitalized as a part of the carrying amount of the long -lived The fair value of asset retirement obligations (ARO) are measured using expected cash outflows associated with the ARO. ARO estimates are derived from historical costs and management’s expectations of future cost elements, and therefore, the Company has designated these liabilities as Level 3 financial liabilities. The significant inputs to this fair value measurement include estimates of assets removal, site clean -up -adjusted -year -free Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). In accordance with ASC 606, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. See Note 3. Business Acquisitions The Company determines and allocates the purchase price of an acquired company to the tangible and intangible assets acquired, the liabilities assumed and noncontrolling interest, if applicable, as of the date of acquisition. Results of operations and cash flows of the acquired companies are included in the Company’s operating results from the date of acquisition. The purchase price allocation process requires the Company to use significant estimates and assumptions which may include estimated fair values of intangible assets, assumed from the acquiree under existing contractual obligations, estimated income taxes assumed from the acquiree and estimated fair value of any contingent consideration. The Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, and these estimates and assumptions are inherently uncertain and subject to refinement during the measurement period not to exceed one year from the acquisition date. As a result, any adjustment identified subsequent to the measurement period is included in operating results in the period in which the amount is determined. Cash and Cash Equivalents The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. The Company maintains cash and cash equivalents at financial institutions, which may periodically exceed federally insured amounts. The Company has not experienced any losses on such accounts. Restricted Cash The Company maintains escrow accounts under the terms of the Assai Energy 3.75% Senior Secured Notes and the Assai Energy 4.47% Senior Secured Notes — See Note 10. The escrow accounts are legally restricted disbursement accounts for payment of construction -related Accounts Receivable and Allowance for Doubtful Accounts The Company recognizes accounts receivable at invoiced amounts and maintains a valuation allowance for accounts in which collectability is in question. The carrying amount of accounts receivable represents the amount management expects to collect from outstanding balances. Credit is extended to all qualified customers under various payment terms with no collateral required. The carrying amount of accounts receivable is reduced by amounts that best reflect management’s estimate of the amounts that will not be collected. Management takes into consideration various credit factors including credit worthiness of the customers, the historical experience with the customer, the timeliness of payments on outstanding invoices and the existence of disputed charges. Receivables are written off against the allowance in the period they are determined to be uncollectible. The allowance for doubtful accounts was $132,920 at June 30, 2021 and December 31, 2020. Prepaid Expenses As of June 30, 2021 and December 31, 2020, prepaid expenses consisted primarily of prepaid property insurance premiums, prepaid engineering, procurement and construction deposits, and prepaid royalty expenses related to biogas plants. The Company recognizes those costs over the term of the related agreement. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is recognized using the straight -line -line The cost of assets sold or otherwise disposed of and the accumulated depreciation thereon are removed from the accounts and the resulting gain or loss is reflected in the statement of operations. Expenditures for maintenance and repairs are expensed as incurred and significant major improvements are capitalized and depreciated over the estimated useful life of the asset. Impairment of Long-lived Assets In accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), long -lived The Company evaluates long -lived -in-progress -lived -lived -lived Goodwill Goodwill is the excess of the consideration transferred over the fair value of the acquired assets and assumed liabilities in a business acquisition. The Company accounts for its goodwill pursuant to the provisions of ASC 350 Intangibles — Goodwill and Other (“ASC 350”). In accordance with ASC 350, goodwill is not amortized, but rather tested for impairment annually, or earlier if an event occurs, or circumstances change, that indicate the fair value of a reporting unit may be below its carrying amount. The Company adopted ASU 2017 -04 Goodwill is tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. In connection with the acquisition of GCES in January 2020, the Company recognized $2,754,438 of goodwill during the year ended December 31, 2020. Leases The Company accounts for its operating leases in accordance with ASC 840, Leases (“ASC 840”). The Company is expected to adopt the new lease standard, ASU 2016 -02 Income Taxes Archaea Energy LLC is organized as a limited liability company. Therefore, the Company’s net taxable income or expense is reported on the members’ income tax returns for the year. Archaea Holding, LLC is the majority shareholder of GCES. GCES is consolidated for financial reporting purposes, but files its own income tax returns as a C -Corporation The Company accounts for its income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year 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 earnings in the period that includes the enactment date. Judgement is required in determining the provisions for income and other taxes and related accruals, and deferred tax assets and liabilities. In the ordinary course of business, there are transactions and calculations where the ultimate tax outcome is uncertain. Additionally, the Company’s various tax returns are subject to audit by various tax authorities. Although the Company believes that is estimates are reasonable, actual results could differ from these estimates. Debt Issuance Costs Debt issuance costs include loan acquisition fees which are recorded at cost and are being amortized both on a straight -line -line Derivative Instruments The Company applies the provisions of ASC 815, Derivatives and Hedging, (“ASC 815”). ASC 815 requires each derivative instrument to be recorded and recognized on the consolidated balance sheets at fair value, unless they meet the normal purchase/normal sale criteria and are designated and documented as such. Changes in the fair value of derivative instruments are recognized in earnings. The Company’s offtake agreements were determined to meet the normal purchase/normal sale criteria and were designated and documented as such. As the biogas facilities achieve COD and the offtake agreements take effect, the revenues associated with these offtake agreements will be recognized in accordance with ASC 606. These offtake agreements range from 20 to 25 years and commit the majority of the facility’s natural gas production to the offtaker.

Description of Business and Principles of Consolidation Archaea Energy, LLC (the Company) was founded in November 2018. The Company aims to partner with landfill owners to harness the power of their biogas. The Company looks to source, build and manage projects for the entirety of an energy project’s lifecycle. Through December The Company has not commenced principal operations within the biogas industry and has incurred significant expenditures for the design and development of several biogas facilities. The Company’s activities are subject to certain risks and uncertainties, including the ability to raise additional working capital to complete the biogas facilities and to successfully market its renewable fuel solutions to transportation and other markets.

Segment Reporting The Company reports segment information in two segments: renewable natural gas (RNG) and GCES. The company currently manages RNG as its primary business operations, which is to construct and develop biogas facilities on the sites of landfills for conversion to RNG. RNG has several projects under construction and had not yet generated revenue as of December -party Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as contingent assets and liabilities.

The Company maintains cash and cash equivalents at financial institutions, which may periodically exceed federally insured amounts. The Company has not experienced any losses on such accounts. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are valued at the net present value of the consideration given and represents the amount management expects to collect from outstanding balances. Credit is extended to all qualified customers under various payment terms with no collateral required. The carrying amount of accounts receivable is reduced by amounts that best reflect management’s estimate of the amounts that will not be collected. Management takes into consideration various credit factors including credit worthiness of the customers, the historical experience with the customer, the timeliness of payments on outstanding invoices and the existence of disputed charges.

Depreciation is computed by using the straight -line -line The cost of assets sold or otherwise disposed of and the accumulated depreciation thereon are eliminated from the accounts and the resulting gain or loss is reflected in income. Expenditures for maintenance and repairs are expensed as incurred and significant major improvements are capitalized and depreciated over the estimated useful life of the asset. Impairment of long-lived assets In accordance with ASC 360, Property, Plant and Equipment (“ASC 360”) and intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset or asset group to future undiscounted cash flows expected to be generated by the asset or asset group. Such estimates are based on certain assumptions, which are subject to uncertainty and may materially differ from actual results. 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. The Company evaluates long -lived -in-progress -lived -lived -lived Goodwill Goodwill is the excess of the consideration transferred over the fair value of the acquired assets and assumed liabilities in a business acquisition. The Company accounts for its goodwill pursuant to the provisions of FASB ASC Topic 350.

Summary of Significant Accounting Policies [Line Items]
Summary of Significant Accounting Policies	Note 3 — Summary of Significant Accounting Policies Use of Estimates The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the Consolidated Financial Statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short -term Investments Held in Trust Account Upon the closing of the Initial Public Offering and the Private Placement, the Company was required to place net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement in a Trust Account, which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in money market funds meeting certain conditions under Rule 2a -7 -ended Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000, and investments held in Trust Account. At December Fair Value Measurement Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three -tier The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • • • In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Fair Value of Financial Instruments As of December -term Offering Costs Associated with the Initial Public Offering Offering costs consisted of underwriting, legal, accounting, underwriting commissions and other costs incurred that were directly related to the Initial Public Offering and that were charged to stockholders’ equity upon the completion of the Initial Public Offering. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss applicable to stockholders by the weighted average number of shares of common stock outstanding during the period. The Company has not considered the effect of the warrants sold in the Initial Public Offering and Private Placement to purchase an aggregate of 18,351,762 -dilutive The Company’s statement of operations includes a presentation of income per share for common stock subject to redemption in a manner similar to the two -class Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification, or FASB ASC, 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. 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 income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions 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 Derivative warrant liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815 -15 -assessed The Company accounts for its 18,633,500 common stock warrants issued in connection with its Initial Public Offering (11,862,500) and Private Placement (6,771,000) as derivative warrant liabilities in accordance with ASC 815 -40 -measurement -Carlo Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncement if currently adopted would have a material effect on the Company’s Consolidated Financial Statements.	Note 2 — Summary of Significant Accounting Policies Principles of Consolidation and Financial Statement Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its majority -owned Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short -term Investments Held in Trust Account The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non -operating -current Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re -assessed The Public Warrants and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the carrying value of the instruments to fair value at each reporting period until they are exercised. The initial fair value of the Public Warrants issued in connection with the Initial Public Offering were estimated using a Monte Carlo simulation model. The fair value of the Public Warrants as of June 30, 2021 is based on observable listed prices for such warrants. The fair value of the Private Placement Warrants as of June 30, 2021 is determined using Black -Scholes -current Net Income Per Share of Common Stock The Company’s condensed consolidated statements of operations include a presentation of net income (loss) per share for Class A common stock subject to possible redemption in a manner similar to the two -class -redeemable -redeemable -redeemable The Company has not considered the effect of the warrants sold in the Public Offering (including the consummation of the over -allotment The following table reflects the calculation of basic and diluted net income (loss) per share of common stock: For the Three For the Six Redeemable Class A common stock Numerator: Income allocable to redeemable Class A common stock Income from investments held in Trust Account $ 5,752 $ 43,263 Less: Company’s portion available to be withdrawn to pay taxes (5,752 ) (43,263 ) Net income attributable to redeemable Class A common stock $ — $ — Denominator: Weighted average redeemable Class A common stock Basic and diluted weighted average shares outstanding, redeemable Class A common stock 23,725,000 23,725,000 Basic and diluted net income per share, redeemable Class A common stock $ 0.00 $ 0.00 For the Three For the Six Non-redeemable Class A and Class B common stock Numerator: Net income (loss) minus net income allocable to redeemable Class A common stock Net income (loss) $ (114,348,270 ) $ (105,576,176 ) Net income allocable to redeemable Class A common stock — — Net income (loss) attributable to non-redeemable Class A and Class B $ (114,348,270 ) $ (105,576,176 ) Denominator: Weighted average non-redeemable Class A and Class B Basic and diluted weighted average shares outstanding, non-redeemable 5,933,850 5,933,850 Basic and diluted net loss per share, non-redeemable Class A and Class B common stock $ (19.27 ) $ (17.79 ) Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC Topic 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. 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 income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. As of June 30, 2021 and December 31, 2020, the Company had deferred tax assets of approximately $1,932,000 and $618,000, respectively, with a full valuation allowance against them. FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions 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. There were no unrecognized tax benefits as of June 30, 2021. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of June 30, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The provision for income taxes was de minimis for the three and six months ended June 30, 2021. Recent Accounting Pronouncements In August 2020, the FASB issued Accounting Standard Update (the “ASU”) No. 2020 -06 -20 -40 -linked Management does not believe that any other recently issued, but not yet effective, accounting pronouncement if currently adopted would have a material effect on the Company’s condensed consolidated financial statements.

Summary of Significant Accounting Policies [Line Items]
Summary of Significant Accounting Policies		(3) Summary of Significant Accounting Policies (a) Basis of Presentation The consolidated financial statements of the Company have been prepared on the basis of United States generally accepted accounting principles (U.S. GAAP). (b) Segment Reporting The Company reports segment information in two segments: RNG and electric operations (landfill gas -to-energy • • • • • -venture • -consolidated (c) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Actual results could differ from those estimates. The areas most subject to estimation are the projected sale prices of RIN and LCFS attributes. (d) Noncontrolling Interests Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to the equity holders of Aria Energy LLC. Noncontrolling interests are initially recorded at transaction price which is equal to their fair value and subsequently the amount is adjusted for the proportionate share of earnings and other comprehensive income attributable to the noncontrolling interests and any dividends or distributions paid to the noncontrolling interests. In the second quarter of 2021, noncontrolling interest was extinguished as part of the sale of LES Project Holdings LLC. See note 7 for further discussion on the sale and accompanying accounting treatment. (e) Revenue Recognition The Company generates revenue from the production and sale of electricity, gas, and their renewable energy attributes, and performance of other landfill energy services. Based on requirements of U.S. GAAP, a portion of revenue is accounted for under Accounting Standards Codification (ASC) 840, Leases Revenue from Contracts with Customers. , The following tables display the Company’s revenue by major source for the six months ended June 30, 2021 and 2020: Six Months Ended 2021 2020 Major goods/services Line: Gas commodity $ 14,574 10,947 Gas renewable attributes 41,148 21,932 Gas service 706 483 Electric commodity 19,610 18,702 Electric service 3,430 4,256 Electric renewable attributes 5,016 6,329 Construction 24 7,246 $ 84,508 69,895 Operating Segments RNG $ 56,452 40,607 LFGTE 28,056 29,288 $ 84,508 69,895 Below is a description of accounting policies for each revenue stream: (i) Electricity The Company sells a portion of the electricity it generates under the terms of power purchase agreements or other contractual arrangements which is included in energy revenue. Most PPAs are accounted for as operating leases under ASC 840, as the majority of the output under each PPA is sold to a single offtaker. The PPAs have no minimum lease payments and all of the rental income under these leases is recorded as revenue when the electricity is delivered. PPAs that are not accounted for as leases are considered derivatives. The Company has elected the normal purchase normal sale exception for these contracts, and accounts for these PPAs under ASC 606. Revenue is recognized over time using an output method, as energy delivered best depicts the transfer of goods or services to the customer. Performance obligation for the delivery of energy is generally measured by MWh’s delivered based on contractual prices. Certain of the Company’s generated electricity is sold through energy wholesale markets (New York Independent System Operator (NYISO), New England Independent System Operator (NEISO), and the Pennsylvania, Jersey, Maryland Independent System Operator (PJM)) into the day -ahead -ahead -year -ready (ii) Gas The Company sells the gas it generates pursuant to various contractual arrangements which is included in energy revenue. These gas sales are accounted for as operating leases under ASC 840, as the majority of the output under each contract is sold to a single offtaker. These agreements have no minimum lease payments and all of the rental income under these leases is recorded as revenue when the gas is delivered to the customer based on contractual prices. The Company also has a division that resells biogas it purchases pursuant to various contractual arrangements which is included in energy revenue. This revenue is accounted for under ASC 606. Revenues related to these contracts are recognized at a point in time when control is transferred upon delivery of the biogas. Revenue is recognized on a monthly basis based on the volume of RNG delivered and the price agreed upon with the customer. (iii) Renewable Attributes The Company also generates revenue through the sale of renewable attributes, which is included in energy revenue. The Company’s electric plants generate renewable energy credits, or RECs, as they generate electricity. The majority of the Company’s RECs are generated by plants for which the Company has a PPA to sell all of the outputs (both energy and RECs) to the PPA counterparty and therefore are accounted for as operating leases in accordance with ASC 840, with revenue recognized as the energy and RECs are generated and delivered. For RECs not bundled with a PPA, the Company considers the RECs when held by the Company to be an inventory item, and outputs that are an economic benefit obtained directly through the operation of the plants. For these stand -alone -in-time The Company generates renewable fuel credits called renewable identification numbers, or RINs. Pipeline -quality (iv) Construction Type Contracts The Company, on occasion, enters into contracts to construct energy projects. This contract revenue is recorded under ASC 606 over time, using an input method based on costs incurred. (v) Operation and Maintenance (O&M) The Company provides O&M services at projects owned by third parties which are included in revenue from services. Revenue for these services is recognized under ASC 606. O&M revenue is recognized over time, using the output method, based on the production of electricity from the project. (vi) PPA and O&M Contract Amortization Through acquisitions, the Company has both above and below -market The Company elected to recognize revenue using the right to invoice practical expedient. The Company determined that the amounts invoiced to customers correspond directly with the value to customers and the Company’s satisfaction of the performance obligations to date. Furthermore, with the election of the right to invoice practical expedient, the Company also elects to omit disclosures on the remaining, or unsatisfied performance obligations since the revenue recognized corresponds to the amount that the Company has the right to invoice. (f) Cash and Cash Equivalents The Company considers all investments with an original maturity of three months or less when purchased to be cash equivalents. The Company maintains amounts on deposit with various financial institutions, which may exceed federally insured limits. Management periodically evaluates the creditworthiness of those institutions. The Company has not experienced any losses on such deposits. (g) Accounts Receivable Accounts receivable are stated at the invoiced or estimated amounts adjusted for any allowance for doubtful accounts. An allowance for doubtful accounts is established based on a specific assessment of all invoices that remain unpaid following normal customer payment periods. There was no allowance for doubtful accounts at June 30, 2021 and December 31, 2020 based on the Company’s history with its existing customers. Payments on accounts receivable balances are typically due and paid within 30 days of invoice. (h) Inventory Inventory is stated at the lower of weighted average cost or net realizable value. Inventory consists primarily of engine parts and supplies used in the maintenance of production equipment. (i) Property, Plant and Equipment Property, plant and equipment are recorded at cost. Expenditures for major renewals and betterments that extend the useful life of the assets are capitalized and depreciated over the remaining life of the assets. Maintenance and repair costs incurred by the Company are charged to expense as incurred in cost of energy. Changes in the assumption of useful lives of assets could have a significant impact on the Company’s results of operations and financial condition. Upon sale or retirement, the asset cost and related accumulated depreciation are eliminated from the respective accounts and any resulting gain or loss is recognized in income. Interest incurred on funds borrowed to finance capital projects is capitalized until the project under construction is ready for its intended use. There was no interest capitalized for the six months ended June 30, 2021 and 2020. Depreciation is computed using the straight -line Depreciable life – in years Buildings 20 – 40 Machinery and equipment 10 – 20 Furniture and fixtures 5 (j) Held for Sale During 2020, the Company enacted a plan to sell LES Project Holdings, LLC (LESPH), and accordingly, the business was classified as held for sale through December 31, 2020. An agreement to sell the membership interests of the business subsequently was executed on March 1, 2021. The sale of LESPH was completed on June 10, 2021. Proceeds from the sale were $58,500, which were sent to the lenders of the LESPH debt discussed in note 7. As discussed further in note The assets and liabilities included in the consolidated balance sheet that are held for sale as of December 31, 2020 are as follows: In $000s Current assets: Accounts receivable 2,092 Inventory 3,034 Related party accounts receivable and advances 88 Prepaid expenses and other current assets 686 Total current assets 5,900 Non current assets: Property and equipment 4,906 Intangible assets 82,179 Held for sale valuation allowance (25,293 ) Investment in joint ventures 2,342 Total non current assets 64,134 Total assets held for sale 70,034 Current liabilities Trade accounts payable 824 Accrued and other current liabilities 2,066 Total current liabilities 2,890 Non current liabilities Below market contracts 6,060 Asset retirement obligations 3,584 Total non current liabilities 9,644 Total liabilities held for sale 12,534 The net gain (loss) associated with LESPH included in the net gain (loss) on the Company’s consolidated statements of comprehensive income (loss) was $67,052 and $(6,224) for the six months ended June 30, 2021 and 2020, respectively, of which $67,341 and $(6,262), respectively, were attributable to the Company. (k) Impairment of Long -Lived Assets In accordance with ASC 360, Property, Plant and Equipment For purposes of testing for an impairment loss, a long -lived to the project site and, if applicable, the power purchase agreement also specific to the project site), and liabilities associated with out of market contracts (out of market power purchase agreements, if applicable). There were no triggering events related to the Company’s projects in the Term Loan B portfolio in the six months ended June 30, 2021. Accordingly, no impairment charge was recognized in 2021 for this group of assets. (l) Other Noncurrent Assets The other noncurrent asset as of June 30, 2021 and December 31, 2020 represents long -term (m) Debt Origination Costs Debt origination costs were incurred by the Company in connection with various legal, consulting, and financial costs associated with debt financing and are reported net of accumulated amortization. These charges are being amortized over the term of the related debt agreements using the effective interest rate and are recorded as a reduction to long -term (n) Investments in Joint Ventures Investments in joint ventures are reported on the equity method. Under this method, the Company records its proportional share of its income or losses of joint ventures as equity in income of joint ventures in the consolidated statements of operations. (o) Derivative Instruments The Company applies the provisions of ASC 815, Derivatives and Hedging (p) Asset Retirement Obligations Asset retirement obligations (AROs) associated with long -lived -lived (q) Postretirement Obligations Postretirement benefits amounts recognized in consolidated financial statements are determined on an actuarial basis. The Company obtains an independent actuary valuation of its postretirement obligation annually as of December 31. To calculate the present value of plan liabilities, the discount rate needs to be determined which is an estimate of the interest rate at which the retirement benefits could be effectively settled. The discount rate is determined using the average effective rate derived through matching of projected benefit payments with the discount rate curve published by Citigroup as of each reporting date. See note 10 for further disclosures on postretirement obligations. (r) Other Long -Term Liabilities Other long -term -out (s) Comprehensive (Loss) Income Comprehensive (loss) income consists of net (loss) income and other comprehensive (loss) income. Other comprehensive (loss) income includes certain changes in assets and liabilities recognized directly to equity, such as actuarial gains/losses on the Company’s postretirement plan. (t) Income Taxes Aria Energy LLC is a limited liability company taxed as a partnership and therefore no provision for federal income taxes has been made in the consolidated financial statements since taxable income or loss of Aria Energy LLC is required to be reported by the respective members on their individual income tax returns. In 2016, Congress enacted the Bipartisan Budget Act of 2015 (the Act), which includes major changes in the way the IRS audit entities that are classified as partnerships. In the event the Company is audited by the taxing authority and assessed additional amounts due to the underpayment of tax in previous tax years, the Company intends to make the push -out One of Aria Energy LLC’s subsidiaries is treated as a corporation for tax purposes. Income taxes of this subsidiary are accounted for under the asset and liability method. This entity has reported tax losses since inception; therefore there continues to be a full valuation allowance at June 30, 2021 and December 31, 2020 recorded against its net deferred tax asset. The entity has recorded no income tax expense for the six months ended June 30, 2021 and June 30, 2020. (u) Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of accounts receivable. Certain accounts receivable are concentrated within entities engaged in the energy industry. These industry concentrations may impact the Company’s overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other conditions. Receivables and other contractual arrangements are subject to collateral requirements under the terms of enabling agreements. However, the Company believes that the credit risk posed by industry concentration is offset by the creditworthiness of its customer base. (v) Cost of Energy Cost of energy consists primarily of labor, parts, and outside services required to operate and maintain Company owned project facilities, electricity consumed in the process of gas production, the transportation of gas or transmission of electricity to the delivery point, and royalty payments to landfill owners as stipulated in the gas rights agreements. (w) Fair Value Measurements Fair value is the price at which an asset could be exchanged or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or derived from such prices. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The framework for establishing fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. The Company employs varying methods and assumptions in estimating the fair value of each class of financial instruments for which it is practicable to estimate fair value. For cash and cash equivalents, accounts receivable and trade accounts payables, the carrying amounts approximate fair value due to the short maturity of these instruments. For long -term In accordance with ASC 820, Fair Value Measurement In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques taking into account the characteristics of the asset. In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability. (x) Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board issued ASU No. 2016 -02 Leases (Topic 842) -line term of 12 months or less will be accounted for similar to existing guidance for operating leases today.

(b) Segment Reporting The Company reports segment information in two segments: RNG and electric operations (landfill gas -to-energy • • • • • -venture • -consolidated (c) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Actual results could differ from those estimates. The areas most subject to estimation are the projected sale prices of RIN and LCFS attributes. (d) Noncontrolling Interests Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to the equity holders of Aria Energy LLC. Noncontrolling interests are initially recorded at transaction price which is equal to their fair value and subsequently the amount is adjusted for the proportionate share of earnings and other comprehensive income attributable to the noncontrolling interests and any dividends or distributions paid to the noncontrolling interests. (e) Revenue Recognition The Company generates revenue from the production and sale of electricity, gas, and their renewable energy attributes, and performance of other landfill energy services.

The group of assets and liabilities at the project level includes property and equipment, intangible assets (relating to gas rights agreements specific to the project site and, if applicable, the power purchase agreement also specific to the project site), and liabilities associated with out of market contracts (out of market power purchase agreements, if applicable). The Company recorded a valuation allowance in relation to its sale of LESPH’s assets and liabilities. A definitive Membership Interest Purchase Agreement (MIPA) with Energy Power Investment Company LLC was entered into in March 2021. Given the characteristics of the cooperative sale process, this was treated as a separate transaction from the settlement of the debt (through the execution of the Mutual Release Agreement, discussed in note 2). Since the former will result in a loss, it is recognized as an impairment charge of $25,293 in 2020. The gain resulting from the settlement of the debt will be recognized in 2021 upon the sale of LESPH. There were no triggering events related to the Company’s projects in the Term B Loan portfolio in 2020. Accordingly, no impairment charge was recognized in 2020 for this group of assets. There were impairment charges recorded in 2019 of $1,634: $1,279 was charged to intangible assets and $355 was charged to property and equipment. An impairment charge of $26,167 was recognized in 2018 as a result of non -renewal (l) Other Noncurrent Assets The other noncurrent asset as of December 31, 2020 and 2019 represents long -term (m) Debt Origination Costs Debt origination costs were incurred by the Company in connection with various legal, consulting, and financial costs associated with debt financing and are reported net of accumulated amortization.

Under this method, the Company records its proportional share of its income or losses of joint ventures as equity in income of joint ventures in the consolidated statements of operations. (o) Derivative Instruments The Company applies the provisions of ASC 815, Derivatives and Hedging, (“ASC 815”). ASC 815 requires each derivative instrument to be recorded and recognized on the consolidated balance sheets at fair value, unless they meet the normal purchase/normal sale criteria and are designated and documented as such. Changes in the fair value of derivative instruments are recognized in earnings. (p) Asset Retirement Obligations Asset retirement obligations (AROs) associated with long -lived recognition of an obligation, the Company capitalizes the asset retirement cost by increasing the carrying amount of the related long -lived (q) Postretirement Obligations Postretirement benefits amounts recognized in consolidated financial statements are determined on an actuarial basis. The Company obtains an independent actuary valuation of its postretirement obligation annually as of December 31. To calculate the present value of plan liabilities, the discount rate needs to be determined which is an estimate of the interest rate at which the retirement benefits could be effectively settled. The discount rate is determined using the average effective rate derived through matching of projected benefit payments with the discount rate curve published by Citigroup as of each reporting date. See note 10 for further disclosures on postretirement obligations. (r) Other Long -Term Liabilities Other long -term -out (s) Comprehensive (Loss) Income Comprehensive (loss) income consists of net (loss) income and other comprehensive (loss) income. Other comprehensive (loss) income includes certain changes in assets and liabilities recognized directly to equity, such as actuarial gains/losses on the Company’s postretirement plan. (t) Income Taxes Aria Energy LLC is a limited liability corporation taxed as a partnership and therefore no provision for federal income taxes has been made in the consolidated financial statements since taxable income or loss of Aria Energy LLC is required to be reported by the respective members on their individual income tax returns. In 2016, Congress enacted the Bipartisan Budget Act of 2015 (the Act), which includes major changes in the way the IRS audit entities that are classified as partnerships. In the event the Company is audited by the taxing authority and assessed additional amounts due to the underpayment of tax in previous tax years, the Company intends to make the push -out One of Aria Energy LLC’s subsidiaries is treated as a corporation for tax purposes. Income taxes of this subsidiary are accounted for under the asset and liability method. This entity has reported tax losses since inception, and there is a full valuation allowance of $605 and $504 at December (u) Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of accounts receivable. Certain accounts receivable are concentrated within entities engaged in the energy industry. These industry concentrations may impact the Company’s overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other conditions. Receivables and other contractual arrangements are subject to collateral requirements under the terms of enabling agreements. However, the Company believes that the credit risk posed by industry concentration is offset by the creditworthiness of its customer base. (v) Cost of Energy Cost of energy consists primarily of labor, parts, and outside services required to operate and maintain Company owned project facilities, electricity consumed in the process of gas production, the transportation of gas or transmission of electricity to the delivery point, and royalty payments to landfill owners as stipulated in the gas rights agreements. (w) Fair Value Measurements Fair value is the price at which an asset could be exchanged or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or derived from such prices. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The framework for establishing fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. The Company employs varying methods and assumptions in estimating the fair value of each class of financial instruments for which it is practicable to estimate fair value. For cash and cash equivalents, accounts receivable and trade accounts payables, the carrying amounts approximate fair value due to the short maturity of these instruments. For long -term In accordance with ASC 820, Fair Value Measurement (“ASC 820”), the hierarchy alluded to above is established that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy defines three levels of inputs that may be used to measure fair value: In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques taking into account the characteristics of the asset. In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

Warrants		(8) Derivative Instruments The Company is exposed to certain risks in the normal course of its business operations. The main risks are those relating to the variability of future earnings and cash flows — e.g., market risks, which are managed through the use of derivative instruments. All derivative financial instruments are reported in the consolidated balance sheets at fair value, unless they meet the normal purchase normal sale criteria and are designated and documented as such. The Company has a natural gas variable to fixed priced swap agreement with an original notional quantity of 4,007 MMBTU. The swap agreement provides for a fixed to variable rate swap calculated monthly, until the termination date of the contract, June 30, 2023. The agreement was intended to manage the risk associated with changing commodity prices. Changes in the fair values of natural gas swap are recognized in gain (loss) on swaps and realized losses are recognized as a component of cost of energy expense as summarized in the table below. Valuation of the natural gas swap was calculated by discounting future net cash flows that were based on a forward price curve for natural gas over the life of the contract, with an adjustment for the counterparty’s credit default hedge rate which are considered level 2 inputs in the fair value hierarchy (see note 3(w)). On April 6, 2020 the Company entered into an interest rate cap with a total notional amount of $110,000 and an effective date of April 30, 2020.

Fair Value Measurements [Line Items]
Fair Value Measurements	Note 9 — Fair Value Measurements The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. The Company classifies its U.S. Treasury and equivalent securities as held -to-maturity -to-maturity -to-maturity At December The following table presents information about the Company’s held -to-maturity -to-maturity Fair Value Measured as of December 31, 2020 Level 1 Level 2 Level 3 Total Assets Investments held in Trust Account – U.S. Treasury Securities $ 237,307,717 $ — $ — $ 237,307,717 Liabilities: Warrant Liability – Public Warrants 27,046,487 27,046,487 Warrant Liability – Private Warrants — — 15,542,000 15,542,000 Total fair value $ 237,307,717 $ — $ 42,588,487 $ 279,896,204 The Warrants were accounted for as liabilities in accordance with ASC 815 -40 I nitial Measurement The Company established the initial fair value for the Warrants on October -Scholes -half The key inputs into the Monte Carlo simulation model for the Public Warrants and the Black -Scholes As of Exercise price $ 11.50 Stock price $ 9.39 Term (in years) 6 Volatility 20 % Risk-free interest rate 0.46 % Dividend yield — On October Subsequent Measurement The Warrants are measured at fair value on a recurring basis.

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2021 and December 31, 2020, and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value: Description Quoted Prices Significant Significant Assets: Investments held in Trust Account – U.S. Treasury $ 237,351,433 $ — $ — Liabilities: Derivative warrant liabilities – Public warrants $ 67,616,251 $ — $ — Derivative warrant liabilities – Private placement warrants $ — $ — $ 71,349,396 Description Quoted Prices Significant Significant Assets: Investments held in Trust Account – U.S. Treasury $ 237,308,171 $ — $ — Liabilities: Derivative warrant liabilities – Public warrants $ 27,046,500 $ — $ — Derivative warrant liabilities – Private placement warrants $ — $ — $ 15,541,987 Transfers to/from Levels Level 1 assets include investments in U.S. treasury securities. The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments. The Warrants are accounted for as liabilities in accordance with ASC 815 -40 For periods where no observable traded price is available, the fair value of the Public Warrants was estimated using a Monte Carlo simulation model. For periods subsequent to the detachment of the Public Warrants from the Units, the fair value of the Public Warrants is based on the observable listed price for such warrants. The estimated fair value of the Private Placement Warrants, and the Public Warrants prior to being separately listed and traded, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock -price -free -free -coupon The Warrants are measured at fair value on a recurring basis. The measurement of the Public Warrants as of June 30, 2021 and December 31, 2020 is classified as Level 1 due to the use of an observable market quote in an active market.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance.

Going Concern	(2) Going Concern We have prepared the accompanying consolidated financial statements on the basis that the Company will continue as a going concern. As discussed in note Accordingly, the circumstances of the Term Loan B raise substantial doubt about the Company’s ability to continue as a going concern. Continuation of an entity as a going concern is assumed in financial reporting in the absence of significant information to the contrary. Ordinarily, information that significantly contradicts the going concern assumption relates to the entity’s inability to continue to meet its obligations as they become due without substantial disposition of assets outside the ordinary course of business, restructuring of debt, externally forced revisions of its operations, or similar actions. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.	Note 2 — Going Concern We have prepared the accompanying consolidated financial statements on the basis that the Company will continue as a going concern. As disclosed in note 7, LES Project Holdings LLC (LESPH), a subsidiary of Aria Energy LLC has defaulted on a term note obligation by failing to meet its financial covenants. The contractual maturity of the debt was October 7, 2020. The Company has classified the debt principal amounts of $102,831 as a current long -term debt and associated unpaid interest obligations of $16,008 as accrued and other current liabilities as of December 31, 2020 in the consolidated balance sheets. If the lenders were to require the payment of the LESPH’s debt, the Company does not have the ability to pay the obligation. The obligation is nonrecourse to Aria Energy LLC. On June Further, as discussed in note Accordingly, these circumstances raise substantial doubt about the Company’s ability to continue as a going concern. Continuation of an entity as a going concern is assumed in financial reporting in the absence of significant information to the contrary. Ordinarily, information that significantly contradicts the going concern assumption relates to the entity’s inability to continue to meet its obligations as they become due without substantial disposition of assets outside the ordinary course of business, restructuring of debt, externally forced revisions of its operations, or similar actions. The factors noted above raise substantial doubt about the Company’s ability to continue as a going concern, as the Company does not have the ability to satisfy the debt obligations in the normal course of business. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	N OTE 3 — REVENUE FROM CONTRACTS WITH CUSTOMERS The Company’s revenues are comprised of sales of customized pollution control equipment (Equipment) and maintenance agreement services (Services), renewable electricity generation (REG), renewable natural gas (RNG) and renewable energy attributes. All revenue is recognized when (or as) the Company satisfies its performance obligation(s) under the contract by transferring the promised product or service either when (or as) its customer obtains control of the product or service. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its products or services. RNG The Company’s RNG production started during 2021 with the commencement of Big Run and is currently sold under short -term -based The Company also earns revenue through the sale of environmental attributes known as renewable identification numbers (RINs), which are generated when selling RNG. All 2021 RIN sales were under short -term REG The Company’s REG production started during 2021 with the acquisition of PEI Power LLC (See Note 4) and is typically sold under a market -based The Company also earns revenue through the sale of environmental attributes known as renewable energy credits (RECs), which are generated when selling REG. All 2021 REC sales were under contracts independent from REG sales, and REC revenue is recognized when the REC is transferred to a third party. GCES Equipment and Services The Company’s performance obligations related to the sales of Equipment are satisfied over time because the Company’s performance under each customer contract produces 1) an asset with no alternative future use to the entity, because each products solution is customized to the specific needs of each customer and 2) the Company has enforceable right to payment under the customer termination provisions for convenience. The Company measures progress under these arrangements using an input method based on costs incurred. The Company’s performance obligations related to the sales of Services are satisfied over time because the customer simultaneously receives and consumes the benefits provided by the Company’s performance as it performs. The Company elected to recognize the sales of Services using the “right -to-invoice Contract Assets and Contract Liabilities The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from projects when revenues recognized under the cost -to-cost Contract liabilities from contracts arise when amounts invoiced to customers exceed revenues recognized under the cost -to-cost -term Contract assets and liabilities consisted of the following at June 30, 2021 and December 31, 2020: 2021 2020 Contract assets, current $ 223,386 $ 48,234 Contract liabilities, current (571,950 ) (1,422,685 ) Transaction Price Allocated to Remaining Unsatisfied Performance Obligations Remaining performance obligations at June 30, 2021 were $2,785,920. Projects are included within remaining performance obligations at such time the project is awarded and agreement on contract terms has been reached. Remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned only when a reasonable estimate of total transaction price can be made. Remaining performance obligations include unrecognized revenues to be realized from uncompleted contracts. Although many of the Company’s contracts are subject to cancellation at the election of the customers, in accordance with industry practice, the Company does not limit the amount of unrecognized revenue included within remaining performance obligations due to the inherent substantial economic penalty that would be incurred by customers upon cancellation. The Company believes the reported remaining performance obligations for construction contracts are firm and contract cancellations have not had a material adverse effect on operations of the Company. Remaining performance obligations also include unrecognized revenues expected to be realized over the remaining term of service contracts. However, to the extent a service contract includes a cancellation clause which allows for the termination of such contract by either party without a substantive penalty, the remaining contract term, and therefore, the amount of unrecognized revenues included within remaining performance obligations, is limited to the notice period required for the termination. Remaining performance obligations are comprised of: (a) original contract amounts, (b) change orders for which written confirmations from the customers have been received, (c) pending change orders for which confirmations, in the ordinary course of business, are expected to be received, (d) claim amounts made against customers for which the Company has determined to have a legal basis under existing contractual arrangements and as to which the variable consideration constraint does not apply, and (e) other forms of variable consideration to the extent that such variable consideration has been included within the transaction price of the contracts. Such claim and other variable consideration amounts were immaterial for all periods presented. The following table disaggregates revenue by significant product type for the six months ended June 30, 2021 and 2020: 2021 2020 Equipment $ 3,632,026 $ 2,509,799 REG and RECs 2,237,480 — RNG and RINs 821,224 — Services 90,739 82,962 Total $ 6,781,469 $ 2,592,761	NOTE 3 — REVENUE FROM CONTRACTS WITH CUSTOMERS The Company’s revenues are comprised of sales of customized pollution control equipment (Equipment) and maintenance agreement services (Services) provided solely by the GCES operating segment. All revenue is recognized when (or as) the Company satisfies its performance obligation(s) under the contract (either implicit or explicit) by transferring the promised product or service either when (or as) its customer obtains control of the product or service. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its products or services.

The Company measures progress under these arrangements using an input method based on costs incurred. The Company’s performance obligations related to the sales of Services are satisfied over time because the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the Company performs. The Company elected to recognize the sales of Services using the as -invoiced Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when the right to consideration is unconditional. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from projects when revenues recognized under the cost -to-cost In addition, many time and material arrangements, are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Also included in contract assets are amounts the Company seeks or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders or modifications in dispute or unapproved as to both scope and/or price, or other customer -related Contract liabilities from contracts arise when amounts invoiced to customers exceed revenues recognized under the cost -to-cost -term Contract assets from contracts arise when revenues received exceed amounts invoiced to customers under the cost -to-cost Net contract liabilities consisted of the following at December 31: 2020 2019 Contract assets, current $ 48,234 $ — Contract liabilities, current (1,422,685 ) — Net contract liabilities $ (1,374,451 ) $ — Transaction Price Allocated to Remaining Unsatisfied Performance Obligations Remaining performance obligations at December Projects are included within remaining performance obligations at such time the project is awarded and agreement on contract terms has been reached. Remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned only when a reasonable estimate of total transaction price can be made. Remaining performance obligations include unrecognized revenues to be realized from uncompleted contracts. Although many of the Company’s contracts are subject to cancellation at the election of the customers, in accordance with industry practice, the Company does not limit the amount of unrecognized revenue included within remaining performance obligations due to the inherent substantial economic penalty that would be incurred by customers upon cancellation.

Such claim and other variable consideration amounts were immaterial for all periods presented. Disaggregation of Revenues Revenues are principally derived from the provision of engineering consulting and construction management services to a variety of industrial, commercial, and institutional customers and Original Equipment Manufacturing (OEM) of certain specialty process equipment to the biogas and natural gas industries. Such revenues are performance obligations satisfied exclusively over time and therefore a disaggregation between over time and at a point in time for revenue realization is not applicable.

Fair Value Measurements		Fair Value Measurements Fair value is the price at which an asset could be exchanged, or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or derived from such prices. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The framework for establishing fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. In accordance with ASC 820, Fair Value Measurement (“ASC 820”), the hierarchy discussed above requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy defines three levels of inputs that may be used to measure fair value, as discussed below. In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques taking into account the characteristics of the asset. In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability. The Company’s financial assets and liabilities are classified based on the lowest level of input that is significant for the fair value measurement. The Company reflects transfers between the three levels at the beginning of the reporting period in which the availability of observable inputs no longer justifies classification in the original level. There were no transfers between fair value hierarchy levels for the six months ended June 30, 2021 or the year ended December 31, 2020. As of the six months ended June 30, 2021 and year ended December 31, 2020, the fair value of other financial instruments including cash and cash equivalents, prepaid expenses, accounts payable, accrued and deferred expenses approximate the carrying values because of the short -term -term	Fair Value Measurements Fair value is the price at which an asset could be exchanged, or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability.

Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset or asset group to future undiscounted cash flows expected to be generated by the asset or asset group. Such estimates are based on certain assumptions, which are subject to uncertainty and may materially differ from actual results. 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.

Description of Business and Principles of Consolidation		Description of Business and Principles of Consolidation Archaea Energy LLC was founded in November 2018. The Company aims to partner with landfill owners to harness the power of their biogas. The Company looks to source, build and manage projects for the entirety of an energy project’s lifecycle. Through June 30, 2021, the Company has been primarily engaged in the development of high BTU biogas facilities aimed at providing a renewable fuel source expected to power truck and bus fleets across the United States. The Company has entered into various landfill biogas right agreements with certain landfill owners for the construction and operation of biogas facilities. By partnering with landfill owners, the Company expects to capture and convert landfill gases to generate renewable natural gas. The Company commenced principal operations at its Big Run site in April 2021. The Company continues to incur significant expenditures for the design and development of several biogas facilities, most notable its Assai project located in the Scranton, PA metro area. The Company’s activities are subject to certain risks and uncertainties, including the ability to raise additional capital to complete the biogas facilities and to successfully market its renewable fuel solutions to transportation and other markets. During the year ended December 31, 2020, the Company purchased 100% of Big Run Power Producers, LLC, a biogas facility located in Ashland, Kentucky. This facility started the pilot stage of RNG production during April 2021, and the Company continues to bring additional wells on -line During the year ended December 31, 2020, the Company purchased 72.2% of Gulf Coast Environmental Systems, LLC (“GCES”).

Fair Value on a Nonrecurring Basis		Fair Value on a Nonrecurring Basis Business Acquisitions For acquisitions that are determined to be the acquisition of a business, the Company records the identifiable assets acquired, liabilities assumed and noncontrolling interest, if applicable, at fair value at the date of acquisition on a nonrecurring basis. Fair value may be estimated using comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow method, estimated future cash flows are based on management’s expectations for the future and can include estimates of future biogas production, commodity prices, operating and development costs, and a risk -adjusted Asset Retirement Obligations The Company accounts for asset retirement obligations as required under ASC 410, Asset Retirement and Environmental Obligations, (“ASC 410”). ASC 410 requires the fair value of a liability for an asset retirement obligation be recognized in the period in which the legal obligation arises, with the associated discounted asset retirement costs being capitalized as a part of the carrying amount of the long -lived The fair value of asset retirement obligations (ARO) are measured using expected cash outflows associated with the ARO.

Business Acquisitions		Business Acquisitions The Company determines and allocates the purchase price of an acquired company to the tangible and intangible assets acquired, the liabilities assumed and noncontrolling interest, if applicable, as of the date of acquisition. Results of operations and cash flows of the acquired companies are included in the Company’s operating results from the date of acquisition. The purchase price allocation process requires the Company to use significant estimates and assumptions which may include estimated fair values of intangible assets, assumed from the acquiree under existing contractual obligations, estimated income taxes assumed from the acquiree and estimated fair value of any contingent consideration. The Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, and these estimates and assumptions are inherently uncertain and subject to refinement during the measurement period not to exceed one year from the acquisition date. As a result, any adjustment identified subsequent to the measurement period is included in operating results in the period in which the amount is determined.

Income Taxes	Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification, or FASB ASC, 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. 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 income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return.

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 income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. As of June 30, 2021 and December 31, 2020, the Company had deferred tax assets of approximately $1,932,000 and $618,000, respectively, with a full valuation allowance against them. FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions 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. There were no unrecognized tax benefits as of June 30, 2021. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of June 30, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The provision for income taxes was de minimis for the three and six months ended June 30, 2021.

Fair Value Measurements	Fair Value Measurement Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three -tier The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • • • In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.
Offering Costs Associated with the Initial Public Offering	Offering Costs Associated with the Initial Public Offering Offering costs consisted of underwriting, legal, accounting, underwriting commissions and other costs incurred that were directly related to the Initial Public Offering and that were charged to stockholders’ equity upon the completion of the Initial Public Offering.
Class A Common Stock Subject to Possible Redemption	Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December

Concentration of Credit Risk		(u) Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of accounts receivable. Certain accounts receivable are concentrated within entities engaged in the energy industry. These industry concentrations may impact the Company’s overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other conditions. Receivables and other contractual arrangements are subject to collateral requirements under the terms of enabling agreements. However, the Company believes that the credit risk posed by industry concentration is offset by the creditworthiness of its customer base.

Fair Value Measurements		(w) Fair Value Measurements Fair value is the price at which an asset could be exchanged or a liability transferred in an orderly transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or derived from such prices. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The framework for establishing fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. The Company employs varying methods and assumptions in estimating the fair value of each class of financial instruments for which it is practicable to estimate fair value. For cash and cash equivalents, accounts receivable and trade accounts payables, the carrying amounts approximate fair value due to the short maturity of these instruments. For long -term In accordance with ASC 820, Fair Value Measurement In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques taking into account the characteristics of the asset. In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

The hierarchy defines three levels of inputs that may be used to measure fair value: In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly.

Most PPAs are accounted for as operating leases under ASC 840, as the majority of the output under each PPA is sold to a single offtaker. The PPAs have no minimum lease payments and all of the rental income under these leases is recorded as revenue when the electricity is delivered. PPAs that are not accounted for as leases are considered derivatives. The Company has elected the normal purchase normal sale exception for these contracts, and accounts for these PPAs under ASC 606. Revenue is recognized over time using an output method, as energy delivered best depicts the transfer of goods or services to the customer. Performance obligation for the delivery of energy is generally measured by MWh’s delivered based on contractual prices. Certain of the Company’s generated electricity is sold through energy wholesale markets (New York Independent System Operator (NYISO), New England Independent System Operator (NEISO), and the Pennsylvania, Jersey, Maryland Independent System Operator (PJM)) into the day -ahead -ahead -year -ready (ii) Gas The Company sells the gas it generates pursuant to various contractual arrangements which is included in energy revenue.

These agreements have no minimum lease payments and all of the rental income under these leases is recorded as revenue when the gas is delivered to the customer based on contractual prices. The Company also has a division that resells biogas it purchases pursuant to various contractual arrangements which is included in energy revenue. This revenue is accounted for under ASC 606. Revenues related to these contracts are recognized at a point in time when control is transferred upon delivery of the biogas. Revenue is recognized on a monthly basis based on the volume of RNG delivered and the price agreed upon with the customer. (iii) Renewable Attributes The Company also generates revenue through the sale of renewable attributes, which is included in energy revenue. The Company’s electric plants generate renewable energy credits, or RECs, as they generate electricity. The majority of the Company’s RECs are generated by plants for which the Company has a PPA to sell all of the outputs (both energy and RECs) to the PPA counterparty and therefore are accounted for as operating leases in accordance with ASC 840, with revenue recognized as the energy and RECs are generated and delivered. For RECs not bundled with a PPA, the Company considers the RECs when held by the Company to be an inventory item, and outputs that are an economic benefit obtained directly through the operation of the plants. For these stand -alone -in-time The Company generates renewable fuel credits called renewable identification numbers, or RINs.
