Forward looking statements are based on current expectations, estimates, projections, targets, opinions and/or beliefs of the Company, and such statements involve known and unknown risks, uncertainties and other factors.

The risks and uncertainties that could cause those actual results to differ materially from those expressed or implied by these forward looking statements include, but are not limited to: (a) the ability to recognize the anticipated benefits of the Business Combinations and any transactions contemplated thereby, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth profitably and retain its management and key employees; (b) the possibility that the Company may be adversely affected by other economic, business and/or competitive factors; (c) the Company’s ability to develop and operate new projects; (d) the reduction or elimination of government economic incentives to the renewable energy market; (e) delays in acquisition, financing, construction and development of new projects; (f) the length of development cycles for new projects, including the design and construction processes for the Company’s projects; (g) the Company’s ability to identify suitable locations for new projects; (h) the Company’s dependence on landfill operators; (i) existing regulations and changes to regulations and policies that affect the Company’s operations; (j) decline in public acceptance and support of renewable energy development and projects; (k) demand for renewable energy not being sustained; (l) impacts of climate change, changing weather patterns and conditions, and natural disasters; (m) the ability to secure necessary governmental and regulatory approvals; (n) the Company’s expansion into new business lines and (o) other risks and uncertainties indicated in the Registration Statement on Form S-1 (File No. 333-260094), originally filed by the Company with the SEC on October 6, 2021, as subsequently amended on October 18, 2021 and declared effective by the SEC on October 21, 2021 (the “Registration Statement”), including those under “Risk Factors” therein, and other documents filed or to be filed with the SEC by the Company.

("Archaea" or the "Company"), a Delaware corporation (formerly named Rice Acquisition Corp.), is one of the largest RNG producers in the U.S., with an industry-leading RNG platform primarily focused on capturing and converting waste emissions from landfills and anaerobic digesters into low-carbon RNG and electricity. As of September 30, 2021, Archaea owns and operates a diversified portfolio of 23 LFG recovery and processing projects across 12 states, including 13 LFG to electric projects and 10 projects that produce pipeline-quality RNG.

On September 15, 2021, Archaea consummated the previously announced business combinations pursuant to (i) the Business Combination Agreement, dated April 7, 2021 (as amended, the “Aria Merger Agreement”), by and among Rice Acquisition Corp., a Delaware corporation ("RAC"), Rice Acquisition Holdings LLC, a Delaware limited liability company and direct subsidiary of RAC (“RAC Opco”), LFG Intermediate Co, LLC, a Delaware limited liability company and direct subsidiary of RAC Opco (“RAC Intermediate”), LFG Buyer Co, LLC, a Delaware limited liability company and direct subsidiary of RAC Intermediate (“RAC Buyer”), Inigo Merger Sub, LLC, a Delaware limited liability company and direct subsidiary of RAC Buyer (“Aria Merger Sub”), Aria Energy LLC, a Delaware limited liability company (“Aria”), and Aria Renewable Energy Systems LLC, a Delaware limited liability company, pursuant to which, among other things, Aria Merger Sub was merged with and into Aria, with Aria surviving the merger and becoming a direct subsidiary of RAC Buyer, on the terms and subject to the conditions set forth therein (the transactions contemplated by the Aria Merger Agreement, the “Aria Merger”), and (ii) the Business Combination Agreement, dated April 7, 2021 (as amended, the “Archaea Merger Agreement” and, together with the Aria Merger Agreement, the “Business Combination Agreements”), by and among RAC, RAC Opco, RAC Intermediate, RAC Buyer, Fezzik Merger Sub, LLC, a Delaware limited liability company and direct subsidiary of RAC Buyer (“Archaea Merger Sub”), Archaea Energy LLC, a Delaware limited liability company, and Archaea Energy II LLC, a Delaware limited liability company (“Legacy Archaea”), pursuant to which, among other things, Archaea Merger Sub was merged with and into Legacy Archaea, with Legacy Archaea surviving the merger and becoming a direct subsidiary of RAC Buyer, on the terms and subject to the conditions set forth therein (the transactions contemplated by the Archaea Merger Agreement, the “Archaea Merger” and, together with the Aria Merger, the “Business Combinations”). As further discussed in Note 4 - Business Combinations and Reverse Recapitalization, Legacy Archaea was determined to be the accounting acquirer of the Business Combinations, and Aria was the predecessor to the Company.

Archaea has retained its “up-C” structure, whereby all of the equity interests in Aria and Legacy Archaea are held by RAC Buyer, all of the equity interests in RAC Buyer are held by RAC Intermediate, all of the equity interests in RAC Intermediate are held by Opco and Archaea’s only assets are its equity interests in Opco. In connection with the consummation of the Business Combinations, Opco, or Rice Acquisition Holdings LLC was renamed LFG Acquisition Holdings LLC. In accordance with Accounting Standards Codification ("ASC") 810 - Consolidation, Opco is considered a variable interest entity ("VIE") where Archaea is the sole managing member of Opco, and therefore, the primary beneficiary. As such, Archaea consolidates Opco, and the remaining unitholders that hold economic interest directly at Opco are presented as redeemable noncontrolling interests on the Company’s financial statements.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Opco issued additional Class A Common Units as part of the consideration in the Business Combinations. The ownership structure of Opco upon closing of the Business Combinations, which gives rise to the redeemable noncontrolling interest at Archaea, is as follows:

Equity Holder	Class A Common Units	% Interest
Archaea	52,847,195	45.9	%
Total controlling interests	52,847,195	45.9	%
Aria Holders	23,000,000	20.0	%
Legacy Archaea Holders	33,350,385	29.0	%
Sponsor, Atlas and RAC independent directors	5,931,350	5.2	%
Total redeemable noncontrolling interests	62,281,735	54.1	%
Total	115,128,930	100.0	%

NOTE 2 - Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

These unaudited, interim, consolidated condensed financial statements and notes are prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") and in accordance with the rules and regulations of the SEC. 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. The Company's accounting policies conform to US GAAP and have been consistently applied in the presentation of financial statements. The Company's consolidated condensed financial statements include all wholly-owned subsidiaries and all variable interest entities that the Company determined it is the primary beneficiary. Certain information and disclosures normally included in annual financial statements prepared in accordance with US GAAP have been condensed or omitted.

The Archaea Merger with RAC was accounted for as a reverse recapitalization with Legacy Archaea deemed the accounting acquirer, and therefore, there was no step-up to fair value of any RAC assets or liabilities and no goodwill or other intangible assets were recorded. The Aria Merger was accounted for using the acquisition method of accounting with Aria deemed to be the acquiree for accounting purposes. The Company also determined that Aria is the Company's predecessor and therefore has included the historical financial statements of Aria as predecessor beginning on page 37. The Company recorded the fair value of the net assets acquired from Aria as of the Business Combination Closing Date, and goodwill was recorded. See Note 4 - Business Combinations and Reverse Recapitalization for additional information regarding the Archaea Merger and Aria Merger.

Principles of Consolidation

The consolidated condensed financial statements include the assets, liabilities and results of operations of the Company and its consolidated subsidiaries beginning on September 15, 2021, which includes 16 days of the combined results of the businesses of Legacy Archaea and Aria as operated by the Company after the Business Combination. The consolidated assets, liabilities and results of operations prior to the September 15, 2021 reverse recapitalization are those of Legacy Archaea, the accounting acquirer.

The Company has determined that Opco is a VIE and the Company is the primary beneficiary. Therefore, the Company consolidates Opco, and ownership interests of Opco not owned by the Company are reflected as redeemable noncontrolling interests due to certain redemption features. Entities that are majority-owned by Opco are consolidated. Certain investments in entities are accounted for as equity method investments and included separately in the Company's Condensed Consolidated Balance Sheet.

All intercompany balances and transactions have been eliminated.

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 Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

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 growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

This may make the comparison of the Company’s consolidated condensed 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. The Company will re-evaluate its status as an emerging growth company in June 2022 and may no longer qualify as an emerging growth company.

Use of Estimates

The preparation of consolidated condensed financial statements in conformity with US GAAP 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 consolidated condensed financial statements.

Noncontrolling and Redeemable Noncontrolling Interest

Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to the stockholder's equity of the Company. Noncontrolling interests are initially recorded at the 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. Effective with the Business Combinations, noncontrolling interest includes the economic interest of Opco Class A units not owned by the Company, which has been classified as redeemable noncontrolling interest due to certain provisions that allow for cash settlement at the Company's election. See Note 4 - Business Combinations and Reverse Recapitalization.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.

12

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

The three input levels of the fair value hierarchy are as follows:

•Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

•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.

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 periods ended September 30, 2021 and December 31, 2020.

As of September 30, 2021 and 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 maturity of those items. There were no changes in the methods or assumptions used in the valuation techniques by the Company during the nine months ended September 30, 2021 or the year ended December 31, 2020.

Revenue Recognition

The Company generates revenues from the production and of sales of RNG, renewable electricity generation (“Power”), and associated Environmental Attributes, as well as the performance of other landfill energy operations and maintenance (“O&M”) services. The Company also manufactures and sells customized pollution control equipment and performs associated maintenance agreement services. Based on requirements of US GAAP, a portion of revenue is accounted for under ASC 840 - Leases and a portion under ASC 606 - Revenue from Contracts with Customers. Under ASC 840, lease revenue is recognized generally upon delivery of RNG, electricity and their related renewable Environmental Attributes. Under ASC 606, 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. Based on the terms of the related sales agreements, the amounts recorded under ASC 840 as lease revenue are generally consistent with revenue recognized under ASC 606. For the nine months ended September 30, 2021, approximately 82% of revenue was accounted for under ASC 606 and 18% under ASC 840. For the nine months ended September 30, 2020, 100% of revenue was accounted for under ASC 606.

RNG

The Company’s RNG production commenced in 2021 at its Boyd County facility and has expanded with the acquisition of Aria, which at the time of the Business Combinations owned or operated nine operating RNG facilities. The Company has long-term off-take contracts with creditworthy counterparties for the sale of RNG and related Environmental Attributes. Certain long-term off-take contracts for current production are accounted for as operating leases and have no minimum lease payments. All of the rental income under these leases is recorded as revenue when the RNG is delivered to the customer. RNG not covered by off-take contracts is sold under short-term market-based contracts. When the performance

13

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

obligation is satisfied through the delivery of RNG to the customer, revenue is recognized. The Company receives payments from the sale of RNG production within one month after delivery.

The Company also earns revenue by selling Environmental Attributes, including RINs and LCFS credits, which are generated when producing and selling RNG for use in certain transportation markets. The majority of RINs are generated by plants for which the Company has off-take agreements to sell all of the outputs and are therefore accounted for as operating leases, and revenue is recognized when the RNG is produced and the RNG and associated RIN is transferred to a third party. The remaining RIN and LCFS sales were under short-term contracts, and revenue is recognized when the RIN or LCFS is transferred to a third party.

Power

The Company’s Power production commenced in April 2021 following the acquisition of PEI Power LLC ("PEI") and has expanded as a result of the acquisition of Aria, which at the time of the Business Combinations owned or operated twelve operating landfill gas to electric facilities. A significant portion of the electricity generated is sold and delivered under the terms of Power Purchase Agreements (“PPAs”) or other contractual arrangements. Revenue is recognized based upon the amount of electricity delivered at rates specified under the contracts. Certain PPAs are accounted for as operating leases and have no minimum lease payments. All of the rental income under these leases is recorded as revenue when the electricity is delivered. Power not covered by PPAs is typically sold under a market-based contract with a regional transmission organization or in the wholesale markets. When the performance obligation is satisfied through the delivery of Power to the customer, revenue is recognized. The Company receives payments from the sale of power production within one month after delivery.

Another portion of electricity is also sold through energy wholesale markets (NYISO, ISO-NE, and PJM) into the day-ahead market. Revenue is recognized based upon the amount of electricity delivered into the day-ahead market and the day-ahead market’s clearing prices.

The Company also sells capacity into the month-ahead and three-year ahead markets in the wholesale markets noted above. Capacity revenues are recognized when contractually earned and consist of revenues billed to a third party at a negotiated contract price for making installed generation capacity available to satisfy system integrity and reliability requirements.

The Company also earns revenue by selling RECs, which are generated when producing and selling Power generated from renewable energy. For REC sales that are under contracts independent from Power sales, revenue is recognized when the REC is transferred to a third party. For REC sales that are bundled with Power sales, revenue is recognized at the time Power is produced when an active market and a sales agreement exist for the RECs.

Operation and Maintenance (“O&M”)

The Company also generates revenues by providing O&M services at projects owned by third parties which are also included in Energy revenue. In addition, the Company also provides O&M services at projects owned by its equity method investment, Mavrix, LLC ("Mavrix"). Revenue for these services is recognized upon the services being provided following contractual arrangements primarily based on the production of RNG or Power from the project.

Equipment and Associated 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 an 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 the associated 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 the associated services using the “right-to-invoice” practical expedient.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

See Note 5 - Revenues for further discussion.

Business Combinations

For business combinations that meet the accounting definition of a business, 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 at fair value. 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 discount rate. Revenues and costs of the acquired companies are included in the Company's operating results from the date of acquisition.

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. The Company’s acquisitions are discussed in Note 4 - Business Combinations and Reverse Recapitalization.

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 - Debt. The escrow accounts are legally restricted disbursement accounts for payment of construction-related costs for the Assai biogas project, as well as for future interest and principal payments to the secured investors and future royalty payments. Due to these arrangements, the Company has classified the amounts in escrow as restricted cash.

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. There were no material credit allowances as of September 30, 2021 or December 31, 2020.

Inventory

Inventory is stated at the lower of weighted average cost or net realizable value. Inventory consists primarily of manufacturing parts and supplies used in the maintenance of production equipment.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, net of accumulated depreciation and impairments. Depreciation is recognized using the straight-line method at rates based on the estimated useful lives of the various classes of property, plant and equipment. Estimates of useful lives are based upon a variety of factors including durability of the asset, the amount of usage that is expected from the asset and the Company’s business plans for the asset. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Subsequent changes in regulations, business strategies or other factors could lead to a change in the useful life of an asset.

Costs associated with the construction of biogas facilities are capitalized during the construction period. Capitalized costs include direct costs including engineering, pipeline and plant construction, wages and benefits, consulting, equipment, and other overhead costs. When a biogas plant is placed in service, the costs associated with the biogas plant will be transferred from construction in progress to property and equipment and depreciated over its expected useful life.

Costs of improvements that extend the lives of existing properties are capitalized, whereas maintenance and repairs are expensed as incurred.

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Impairment of Long-Lived Assets

Long-lived 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 assets, such as property, plant and equipment, including construction in progress, when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. When the Company believes an impairment condition may have occurred, it is required to estimate the undiscounted future cash flows associated with the long-lived asset or group of long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities for long-lived assets that are expected to be held and used. If the Company determines that the undiscounted cash flows from an asset to be held and used are less than the carrying amount of the asset, or if the Company has classified an asset as held for sale, the Company would evaluate fair value to determine the amount of any impairment charge.

Equity Method Investments

Investments in entities which the Company does not control or variable interest entities in which the Company is not the primary beneficiary are accounted for using the equity method of accounting. Under this method, the Company records its proportional share of equity earnings or losses in the consolidated condensed statements of operations. Investments are increased by additional contributions and earnings and are reduced by equity losses and distributions.

Goodwill

Goodwill is determined as the excess of the consideration transferred over the fair value of the acquired assets and assumed liabilities in a business combination. Goodwill is not amortized, but rather tested for impairment annually on October 1, or earlier if an event occurs, or circumstances change, that indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment indicates that it is more likely than not that the fair value of the reporting unit is less than its carrying amount including goodwill, the Company will then perform a quantitative goodwill impairment test.

Asset Retirement Obligations

The Company recognizes a liability for obligations which the Company has a legal or a contractual obligation to remove a long-lived asset. Liabilities are recorded at estimated fair value with the associated asset retirement costs being capitalized as a part of the carrying amount of the long-lived asset. Accretion expense is recognized over time as the discounted liabilities are accreted to their expected settlement value and is included in Depreciation, amortization and accretion in the consolidated condensed statement of operations. The Company has recognized asset retirement obligations ("AROs") arising from legal or regulatory requirements to perform certain asset retirement activities at the time that certain contracts terminate, including the costs of removing our facilities from the landfill property and returning the land to the state it was in prior to our facility construction.

The fair value of asset retirement obligations 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 cost estimates of assets removal, site clean-up, transportation and remediation costs, inflation estimates, and the Company's credit-adjusted risk-free rate.

Postretirement Obligations

Postretirement benefits amounts recognized in consolidated condensed financial statements are determined on an actuarial basis. The Company obtains an independent actuary valuation of its postretirement obligation annually as of December 31.

16

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

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.

Income Taxes

As a result of the Company’s up-C structure effective with the Business Combinations, the Company expects to be a tax-paying entity. However, as the Company has historically been loss-making, any deferred tax assets created as a result of net operating losses and other deferred tax assets for the excess of tax basis in Archaea Energy Inc.'s investment in Opco would be offset by a full valuation allowance. Prior to the Business Combinations, Legacy Archaea and its subsidiaries were organized as a limited liability company, with the exception of one partially-owned subsidiary which filed 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 basis 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.

Judgment 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 its estimates are reasonable, actual results could differ from these estimates.

Derivative Instruments

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 under US GAAP. Derivative instruments are recognized on the consolidated balance sheets at fair value, with subsequent changes included in earnings. Certain contracts that are used to manage exposure to commodity prices are accounted for as derivatives, unless they meet the normal purchase/normal sale criteria and are designated and documented as such.

Share-based Compensation

The Company accounts for share-based compensation at fair value. Restricted stock units are valued at the grant date using the market price of the Company’s Class A Common Stock. The Company records share-based compensation cost, net of actual forfeitures, on a straight-line basis over the requisite service period of the respective award.

NOTE 3 – Recently Issued and Adopted Accounting Standards

In February 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-02 “Leases (Topic 842)” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous generally accepted accounting principles and the new requirements under Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous generally accepted accounting principles. ASU 2016-02 is effective for the Company for fiscal years beginning after December 15, 2021 with early adoption permitted.

The Company will adopt Topic 842 as of January 1, 2022, and it is not expected to have a material impact on the financial condition, results of operations, or cash flows.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes, to simplify the accounting for income taxes. The guidance eliminates certain exceptions related to the approach for intra-period tax allocations, the methodology for calculating income taxes in an interim period, and recognition of the deferred tax liabilities for outside basis differences

17

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

related to changes in ownership of equity method investments and foreign subsidiaries. The guidance also simplifies aspects of accounting for franchise taxes, enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years with early adoption permitted. The Company adopted ASU No. 2019-12 as of January 1, 2021, and the adoption of this guidance did not have a material impact on the consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASC 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional guidance for a limited period of time to ease the transition from LIBOR to an alternative reference rate. The guidance intends to address certain concerns relating to accounting for contract modifications and hedge accounting. These optional expedients and exceptions to applying GAAP, assuming certain criteria are met, are allowed through December 31, 2022. The Company is currently evaluating the provisions of this update and has not yet determined whether it will elect the optional expedients. The Company does not expect the transition to an alternative rate to have a material impact on its business, operations or liquidity.

NOTE 4 – Business Combinations and Reverse Recapitalization

On September 15, 2021, Archaea consummated the previously announced Business Combinations with Aria and Legacy Archaea, as described in Note 1 - Organization and Description of Business.

Reverse Recapitalization

Legacy Archaea is considered the accounting acquirer of the Business Combinations because Legacy Archaea Holders have the largest portion of the voting power of the Company and Legacy Archaea’s senior management comprise the majority of the executive management of the Company. Additionally, the Legacy Archaea Holders appointed the majority of board members exclusive of the independent board members. The Archaea Merger represents a reverse merger and is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, RAC is treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Archaea Merger is treated as the equivalent of Legacy Archaea issuing shares for the net assets of RAC, accompanied by a recapitalization. The net assets of RAC were stated at historical cost, no goodwill or other intangible assets were recorded.

The Archaea Closing Merger Consideration consisted of 33,350,385 newly issued Opco Class A units and 33,350,385 newly issued shares of Class B Common Stock.

In the reverse recapitalization, the Company received $236.9 million in gross cash proceeds from RAC upon Closing. For accounting purposes, these cash proceeds were treated as the equivalent of proceeds for issuance of the following outstanding shares and warrants at the time of Closing:

•23,680,528 shares of Class A Common Stock, after redemptions

•5,931,350 shares of Class B Common Stock

•11,862,492 Public Warrants and 6,771,000 Private Placement Warrants, each exercisable at a price of $11.50 per share. See Note 11 - Derivatives for further discussion.

In connection with the Business Combinations, the Company incurred approximately $40.5 million of equity issuance costs, mainly consisting of underwriting, legal, consulting, and other professional fees, which are recorded to additional paid-in capital as a reduction of proceeds.

PIPE Financing

On April 7, 2021, in connection with its entry into the Business Combination Agreements, the Company entered into subscription agreements (each, an “Initial Subscription Agreement”) with certain investors (the “Initial PIPE Investors”) pursuant to which, among other things, the Initial PIPE Investors agreed to subscribe for and purchase, and the Company agreed to issue and sell to the Initial PIPE Investors, an aggregate of 30.0 million shares of the Company’s Class A

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Common Stock for an aggregate purchase price of $300.0 million ($10.00 per share), on the terms and subject to the conditions set forth therein (the “Initial PIPE Financing”).

Additionally, on April 7, 2021, RAC, RAC Opco, Sponsor and Atlas Point Energy Infrastructure Fund, LLC, a Delaware limited liability company (“Atlas”), entered into an Amendment to Forward Purchase Agreement (the “FPA Amendment”) pursuant to which the Forward Purchase Agreement, dated as of September 30, 2020 (the “Original FPA Agreement” and, together with the FPA Amendment, the “FPA”), by and among such parties was amended to provide that Atlas shall purchase a total of $20.0 million of Forward Purchase Securities (as defined in the Original FPA Agreement) and the Forward Purchase Warrants (as defined in the Original FPA Agreement) will consist of one-eighth of one redeemable warrant (where each whole redeemable warrant is exercisable to purchase one share of Class A Common Stock at an exercise price of $11.50 per share). Atlas satisfied its obligation to purchase the Forward Purchase Securities by participating in the PIPE Financing, and upon consummation of the Combinations, Atlas received 250,000 warrants (each exercisable for one share of Class A Common Stock at a price of $11.50).

On September 13, 2021, due to the expectation that one of the Initial PIPE Investors would not be able to fulfill its $25.0 million commitment for 2.5 million shares ($10.00 per share) in the Initial PIPE Financing, the Company entered into additional subscription agreements (each, a “Follow-On Subscription Agreement”) with certain investors (the “Follow-On PIPE Investors” and, together with the Initial PIPE Investors, the “PIPE Investors”) pursuant to which, among other things, the Follow-On PIPE Investors agreed to subscribe for and purchase from the Company, and the Company agreed to issue and sell to the Follow-On PIPE Investors, an aggregate of 1,666,667 newly issued shares of the Company’s Class A Common Stock for an aggregate purchase price of $25.0 million ($15.00 per share), on the terms and subject to the conditions set forth therein (the “Follow-On PIPE Financing” and, together with the Initial PIPE Financing, the “PIPE Financing”). Each Follow-On Subscription Agreement is substantially identical to the form of Initial Subscription Agreement.

On the Closing Date, gross consideration of $300 million was received under the PIPE Financing, including the proceeds under the FPA Amendment, in exchange for 29,166,667 shares of Class A Common Stock and 250,000 warrants (each warrant exercisable for one share of Class A Common Stock at a price of $11.50).

Aria Merger

Aria was acquired to complement Archaea's existing RNG assets and for its operational expertise in the renewable gas industry. Aria was determined to be a VIE immediately prior to the Business Combination. Concurrent with the Business Combinations, the Company became the primary beneficiary of Aria. The Aria Merger Consideration consisted of both cash consideration and consideration in the form of newly issued Opco Class A units and newly issued shares of the Company’s Class B Common Stock. The cash component of the Aria Merger Consideration paid upon Closing was $377.1 million paid to Aria Holders, subject to certain future adjustments set forth in the Aria Merger Agreement, and $91.1 million for repayment of Aria debt. The remainder of the Aria Closing Merger Consideration consisted of 23.0 million Opco Class A units and 23.0 million shares of Class B Common Stock.

Total consideration was determined to be as follows:

The Aria Merger represented an acquisition of a business and was accounted for using the acquisition method, whereby all of the assets acquired, liabilities assumed and noncontrolling interests were recognized at their fair value on the acquisition date, with any excess of the purchase price over the estimated fair value recorded as goodwill. Certain data to complete the purchase price allocation is not yet available, including but not limited to final appraisals of certain assets acquired and liabilities assumed. The Company will finalize the purchase price allocation during the 12-month period following the Closing, during which time the value of the assets and liabilities may be revised as appropriate. The following table sets forth the preliminary allocation of the Aria Merger consideration.

Equity method investments	232,619

Goodwill	24,257

Fair value of liabilities assumed:

Other long-term liabilities	8,879
Amount attributable to liabilities assumed	145,588
Net assets acquired	863,147
Total Aria Merger consideration	$	863,147

The goodwill is primarily attributable to the expected synergies Archaea believes will be created as a result of the combined companies, the ability to enhance Aria's current RNG assets, and the ability to convert certain of Aria's power assets to RNG assets. We expect a majority, if not all of the goodwill, to be assigned to the RNG reporting unit upon finalizing the purchase price allocation. Due the existence of cumulative losses, no deferred taxes are recorded for the Aria merger transaction.

Included in the consolidated statement of operations for both the three and nine months ending September 30, 2021 are revenues of $6.2 million and net income of $0.6 million related to results of Aria for the 16 day period from the Closing of the Business Combinations through September 30, 2021. The Company recognized transaction costs of $2.7 million during the three and nine months ended September 30, 2021 related to the Business Combinations.

Stockholders’ Agreement

Pursuant to the terms of the Stockholders Agreement, the Company Holders (as defined in the Stockholders Agreement) were granted certain customary registration rights. Also, the Aria Holders (as defined in the Stockholders Agreement) are subject to a 180-day lock-up period on transferring their equity interests in the Company and Opco, while the Legacy Archaea Holders (as defined in the Stockholders Agreement) are subject to a lock-up period (i) ending on the date that is the two-year anniversary of the Closing Date solely with respect to the Company Interests distributed by Archaea Energy LLC after the one-year anniversary of the Closing Date to the Legacy Archaea Holders who are members of management of the Company as of the Closing or their Affiliates (as defined in the Stockholders Agreement) and (ii) ending on the date that is the one-year anniversary of the Closing Date with respect to all other Company Interests issued to the Legacy Archaea Holders at the Closing other than those described in the immediately foregoing clause (i).

The lock-up restrictions applicable to the Aria Holders are subject to early expiration based on the per share trading price of the Company’s Class A Common Stock, par value $0.0001, as set forth in the Stockholders Agreement. The Stockholders Agreement generally provides that if, following the Closing, the last sale price of the Class A Common Stock (as adjusted for the stock splits, stock dividends, reorganizations, recapitalizations and similar transactions) (the "trading share price") on the principal exchange on which such securities are then listed or quoted for any 10 trading days within any 15 trading-day period commencing 15 days after the Closing, exceeds (i) $13.50 per share, then the Aria Holders, together with their permitted transferees, may transfer the equity interests in the Company that they received pursuant to the Aria Merger Agreement (the "Aria Closing Shares) during the 180-day lock-up period without restriction in an amount up to one-third of the Aria Closing Shares, (ii) $16.00 per share, then the Aria Holders, together with their permitted transferees, may transfer up to an additional one-third of the Aria Closing Shares in excess of the Aria Closing Shares described in the foregoing clause (i) (i.e., up to two-thirds of the Aria Closing Shares in the aggregate) without restriction, and (iii) $19.00 per share, then the Aria Holders, together with their permitted transferees, may transfer any of the Aria Closing Shares without restriction. As of November 11, 2021, all of the Aria Closing Shares were no longer subject to the lock-up restrictions due to Class A Common Stock trading prices.

Predecessor Financial Statements

Archaea determined that Aria is the predecessor to the Company due to the relative fair values of the Company and legacy operations Aria had compared to Archaea. As such, we have included Aria's consolidated statements of operations for the periods from July 1 to September 14, 2021, from January 1 to September 14, 2021, and the three months and nine months ended September 30, 2020, and the consolidated balance sheet as of December 31, 2020 following the Notes to the Company's Consolidated Condensed Financial Statements for comparative purposes.

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 measure of progress exceed the amounts invoiced to customers, as the amounts cannot be billed under the terms of the contracts. Contract liabilities from contracts arise when amounts invoiced to customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from customers on certain contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when such revenue is expected to be recognized.

Contract assets and liabilities consisted of the following as of September 30, 2021 and December 31, 2020:

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 and firm sales contracts with original terms in excess of one year.

As a result of the Aria Merger, the Company holds 50% interest in two joint ventures, Mavrix and Sunshine Gas Producers, LLC. ("SGP"), which are accounted for using the equity method. In addition, the Company also owns several other investments accounted for using the equity method of accounting.

Under the terms of the original Mavrix, LLC Contribution Agreement dated September 30, 2017, the Company is required to make an earn-out payment to its joint venture partner holding the other 50% membership in Mavrix in an amount up to $9.55 million.

NOTE 8 – Goodwill and Intangible Assets

Goodwill

At September 30, 2021, the Company had $27.0 million of goodwill, all of which is allocated to the RNG segment. The goodwill is primarily associated with the acquisition of Aria in the Business Combinations.

Intangible Assets

Intangible assets consist of biogas rights agreements, off-take agreements, operations and maintenance contracts, an RNG purchase contract, customer relationships and trade names that were recognized as a result of the allocation of the purchase price under business acquisitions based on their future value to the Company, and such intangible assets will be amortized over their estimated useful lives. The biogas rights agreements have various renewal terms in their underlying contracts that are factored into the useful lives when amortizing the intangible asset.

Intangible assets consist of the following as of September 30, 2021 and December 31, 2020:

The biogas rights agreements, some of which are evergreen, are being amortized over their expected useful lives ranging from 4 years to 30 years, and the amortization period for each agreement begins once the associated facility commences operations. Total amortization expense was approximately $1.6 million for both the three and nine months ended September 30, 2021. The annual amortization expense is expected to be approximately $35 million for each of the next 5 years.

In March 2021, the Company had received notification from the lending institution that the full amount of the loan had been forgiven, and the proceeds were recorded in other income in the first quarter of 2021. The amount of the proceeds received under this loan at December 31, 2020 was reflected in the accompanying balance sheets as other long-term liability.

In December 2020, GCES had received notification from the lending institution that the full amount of the loan had been forgiven, and the proceeds were recorded in other income in the fourth quarter of 2020.

NOTE 11 – Derivative Instruments

Warrant Liabilities

The Public Warrants, Forward Purchase Warrants, and Private Placement Warrants contain exercise and settlement features that preclude them from being classified within in shareholders’ equity, and therefore are recognized as derivative liabilities. The Company recognizes these warrant instruments as liabilities at fair value with changes in fair value included within other income (loss) in the Company’s consolidated condensed statements of operations. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. As of September 30, 2021, the Company had 12,112,492 total Public Warrants and Forward Purchase Warrants (together the "Redeemable Warrants") and 6,771,000 Private Placement Warrants outstanding. Redeemable Warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire on September 15, 2026, or earlier upon redemption or liquidation. The Redeemable Warrants became exercisable on October 26, 2021, and the Company may redeem the outstanding Redeemable Warrants even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the last sale price of the Class A Common Stock equals or exceeds $10.00 per share on the last trading day before the notice of redemption is sent to the warrant holders, the Company may redeem the Redeemable Warrants for cash at a price of $0.10 per warrant. During the 30-day redemption period in this instance, warrant holders can elect to exercise their warrants on a cash or cashless basis.

If the last sale price of the Class A Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day before the notice of redemption is sent to the warrant holders, the Company may redeem the outstanding Redeemable Warrants for cash at a price of $0.01 per warrant. If the Company calls the Redeemable Warrants for redemption for cash as described above, the Company will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering Redeemable Warrants for that number of shares of Class A Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Common Stock underlying the Warrants,

28

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

multiplied by the difference between the exercise price of the Warrants and the “fair market value” (as defined in the following sentence) by (y) the fair market value. The “fair market value” of shares of the Company's Class A Common Stock shall mean the volume weighted average price of our shares of Class A Common Stock as reported during the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants; however, in no event will the Redeemable Warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Class A Common Stock per Redeemable Warrant (subject to adjustment).

Each Private Placement Warrant is exercisable to purchase one share of Class A Common Stock or, in certain circumstances, one Class A unit of Opco (and corresponding share of Class B Common Stock). The Private Placement Warrants expire on September 15, 2026 or earlier upon redemption or liquidation. Private Placement Warrants are nonredeemable so long as they are held by the initial purchasers of the Private Placement Warrants or their permitted transferees. There were no Private Placement Warrants transfers as of September 30, 2021.

The fair value of the Redeemable Warrants is based on observable listed prices on NYSE for such warrants (a Level 1 measurement). The fair value of the Private Placement Warrants was estimated using the Black-Scholes option pricing model (a Level 3 measurement).

The Company used the following assumptions to estimate the fair value of the Private Placement Warrants:

	As of September 15, 2021 at Initial Measurement		September 30, 2021
Stock price	$18.05		$18.94
Exercise price	$11.50		$11.50
Volatility	45.8	%	46.3	%
Expected term (years)	5.0		5.0
Risk-free interest rate	0.79	%	0.97	%

The change in the fair value of the warrant liabilities is recognized in gain (loss) on derivative contracts in the Consolidated Condensed Statement of Operations. The changes of the Redeemable Warrants and Private Placement Warrants through September 30, 2021 is as follows:

(in thousands)
Warrant liabilities as of September 15, 2021 (Closing Date)	$	150,153
Change in fair value - Closing Date through September 30, 2021	10,477
Warrant liabilities as of September 30, 2021	$	160,630

In November 2021, the Company issued a redemption notice to the holders of the Company's Redeemable Warrants. The Company will redeem all Public Warrants for Class A Common Stock that remain outstanding at 5:00 p.m., New York City time, on December 6, 2021 (the "Redemption Date") for a redemption price of $0.10 per Public Warrant. The Public Warrants were issued under the Warrant Agreement, dated October 21, 2020, by and among the Company, LFG Acquisition Holdings LLC and Continental Stock Transfer & Trust Company (as warrant agent), as part of the units sold in the IPO. In addition, the Company will redeem all of the Forward Purchase Warrants that remain outstanding on the Redemption Date at a redemption price of $0.10 per Forward Purchase Warrant. The Private Placement Warrants held by the initial holders or their permitted transferees are not subject to the redemption.

Natural Gas Swap

In conjunction with the Business Combinations, the Company assumed a natural gas variable to fixed priced swap agreement entered into by Aria. The swap agreement provides for a fixed to variable rate swap calculated monthly thorough the termination date of June 30, 2023. The agreement was intended to manage the risk associated with changing commodity prices. The agreement has a remaining notional of 382,800 MMBtu as of September 30, 2021. The Company made no cash payments for the natural gas swap for the period from the Closing Date through September 30, 2021.

29

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Changes in the fair values of the natural gas swap are recognized in gain (loss) on derivative contracts and realized losses are recognized as a component of cost of energy expense in the Consolidated Condensed Statement of Operations. 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 remaining life of the contract (a Level 2 measurement), with an adjustment for each counterparty's credit rate risk.

The following summarizes the balance sheet classification and fair value of the Company’s derivative instruments:

NOTE 12 – Asset Retirement Obligations

The Company has asset retirement obligations ("ARO") associated with the future environmental remediation responsibility to restore the land and remove biogas plants and related facilities within one year of the expiration of certain operating lease agreements. The fair value of the ARO is measured using expected cash outflows associated with the ARO, adjusted for inflation and discounted at our credit-adjusted risk-free rate when the liability is initially recorded. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.

The following summarizes changes in the Company’s ARO liabilities for the year-to-date periods ending September 30, 2021 and December 31, 2020:

NOTE 13 – Redeemable Noncontrolling Interest and Stockholders’ Equity

Redeemable Noncontrolling Interest

The redeemable noncontrolling interest relates to Opco Class A units, including units issued in connection with the Business Combinations and units owned by the Sponsor, Atlas or Company directors. As of September 30, 2021, the Company directly owned approximately 45.9% of the interest in Opco and the redeemable noncontrolling interest was 54.1%. Owners of the redeemable Opco Class A units own an equal number of shares of Class B Common Stock. Due to

30

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

certain cash redemption provisions of these Opco Class A units, the Company has accounted for the redeemable noncontrolling interest as temporary equity.

Stockholders' Equity

Preferred Stock

The Company is authorized to issue 10.0 million shares of preferred stock, par value $0.0001 per share. As of September 30, 2021 and December 31, 2020, no shares of preferred stock were issued or outstanding.

Class A Common Stock

The Company is authorized to issue 900.0 million shares of Class A Common Stock with a par value of $0.0001 per share. As of September 30, 2021, there were 52,847,195 shares of Class A Common Stock issued and outstanding.

Class B Common Stock

The Company is authorized to issue 190.0 million shares of Class B Common Stock with a par value of $0.0001 per share. As of September 30, 2021, there were 62,281,735 shares of Class B Common Stock issued and outstanding. Class B Common Stock represents a non-economic interest in the Company.

Voting Rights

Holders of the Class A Common Stock and holders of the Class B Common Stock will vote together as a single class on all matters submitted to a vote of the stockholders, except as required by law. Each share of common stock will have one vote on all such matters.

Nonredeemable Noncontrolling Interest

Noncontrolling interest includes the portion of equity ownership in one partially-owned subsidiary that is not attributable to the unitholders of Opco.

NOTE 14 – Share-Based Compensation

In connection with Business Combinations, the Company adopted the 2021 Omnibus Incentive Plan (the "Plan"). The Company may grant restricted stock, restricted stock units, incentive and non-qualified stock options, stock appreciation rights, performance awards, stock awards and other stock-based awards to officers, directors, employees and consultants under the terms of the Plan. There are 11.3 million shares authorized under the plan as of September 30, 2021, and all authorized shares remain available for future issuance as of September 30, 2021.

Restricted Stock

The Company has plans to grant restricted stock units ("RSUs") to certain employees, including certain members of management, and non-employee directors. Until the RSUs vest and settle as shares of stock, holders of RSUs will not have voting rights and will not have any rights to receive dividends. RSUs will be subject to forfeiture restrictions and cannot be sold, transferred, or disposed of during the restriction period.

The Company recognized $0.5 million of share-based compensation expense during the three months and nine months ended September 30, 2021 related to liability classified RSUs for which the inception date preceded the grant date, and the grant date has not yet occurred.

Series A Incentive Plan

Legacy Archaea adopted a Series A Incentive Plan in 2018 to provide economic incentives to select employees and other service providers in order to align their interests with equity holders of Legacy Archaea. The Series A unit awards were

31

ARCHAEA ENERGY INC.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

determined to be equity classified. These Series A unit awards were granted by, and for equity interest in, Archaea Energy LLC. As of December 31, 2020, there were 4,000 vested and 4,500 unvested Series A unit awards. Under the original terms of the awards, all unvested Series A units outstanding were vested upon Closing of Business Combinations.

Series A Incentive Plan activities related to unvested units during the nine months ended September 30, 2021 were as follows:

	Series A Incentive Units	Weighted Average Grant Date Fair Value (per share)
Nonvested at December 31, 2020	4,500	$	—
Granted	1,500	$	1,566
Forfeited	(250)	$	—
Vested	(5,750)	$	409
Nonvested at September 30, 2021	—	$	—

For the three and nine months ended September 30, 2021, Legacy Archaea recognized compensation costs of $2.1 million and $2.3 million, respectively, related to Series A units awards. The Company recognized no expense related to the Series A unit awards in 2020. As a result of the Business Combinations, the Series A Incentive Plan is no longer applicable to the Company.

NOTE 15 – Employee Benefit Plans

401(k) Plans

The Company maintains two separate qualified tax deferred 401(k) plans, which cover all employees who meet the one of 401(k) plan’s eligibility requirements. The Company matches up to 100% of each participant’s contribution up to a maximum of 5% of the participant’s eligible compensation.

Postretirement Obligations

Effective with the Business Combinations, the Company sponsors an unfunded defined benefit health care plan that provides postretirement medical benefits to certain legacy Aria full-time employees who meet minimum age and service requirements.

Net periodic benefit cost recognized in the consolidated statements of comprehensive loss following the Business Combinations was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,

NOTE 16 – Risk and Uncertainties

The Company maintains at a financial institution cash and cash equivalents which may periodically exceed federally insured limits. It is the opinion of management that the solvency of the financial institution is not of particular concern currently. As such, management believes the Company is not exposed to any significant credit risk related to cash and cash equivalents.

NOTE 17 – Provision for Income Tax

The income tax provision for the three-and-nine months ended September 30, 2021 and 2020 is as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2021		2020		2021		2020
Income tax provision	$	—	$	—	$	—	$	—

The Company recognized federal, and state income tax expense of $0 million and $0 million during the three and nine months ended September 30, 2021, respectively, compared to $0 million during the same periods in 2020. The effective tax rates for the three-and-nine months ended September 30, 2021 were 0% and 0%, respectively, and were 0% during the same periods in 2020. The difference between the Company’s effective tax rate for the period ended September 30, 2021 and the U.S. statutory tax rate of 21% was primarily due to a full valuation allowance recorded on the Company’s net U.S. deferred tax assets. The Company did not record a tax provision for the three-or-nine months ended September 30, 2020 primarily due to Archaea Energy LLC and Aria Energy LLC’s status as a pass-through entity for U.S. federal income tax purposes. The Company evaluates the realizability of the deferred tax assets on a quarterly basis and establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset may not be realized.

No uncertain tax benefits have been recorded in 2021.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The Company analyzed the provisions of the CARES Act and determined there was no significant impact to its income tax for the nine months ended September 30, 2021. Future regulatory guidance under the CARES Act or additional legislation enacted by Congress could impact our tax provision in future periods.

Additionally, the CARES Act is an economic emergency aid package to help mitigate the impact of the COVID-19 pandemic. The Company implemented certain provisions of the CARES Act, specifically securing loans under the Paycheck Protection Program. Under the CARES Act, all provisions of the loans have been forgiven as of September 30, 2021.

NOTE 18 – Net Earnings (Loss) Per Share

The Archaea Merger was accounted for as a reverse recapitalization and is treated as the equivalent of Legacy Archaea receiving proceeds for the issuance of the outstanding Class A and Class B shares, as well as the warrants, of Rice Acquisition Corp. accompanied by a recapitalization. Therefore, Class A Common Stock is outstanding beginning at the Merger date due to the reverse recapitalization.

The Company’s basic earnings per share (EPS) of Class A Common Stock is computed using the weighted average number of Class A Common Stock outstanding during the period. Diluted EPS of Class A Common Stock includes the effect of the Company’s outstanding RSUs, Public Warrants, Forward Purchase Warrants and Private Placement Warrants, if inclusion of these items is dilutive. The dilutive effect of RSUs, Public Warrants, Forward Purchase Warrants and Private Placement Warrants is computed using the treasury stock method.

NOTE 19 - Contingencies

Management has regular litigation reviews, including updates from corporate and outside counsel, to assess the need for accounting recognition or disclosure of contingencies. The Company accrues an undiscounted liability for contingencies where a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. The Company does not believe the ultimate outcome of any currently pending lawsuit will have a material adverse effect upon the Company’s financial statements, and the liability is believed to be only reasonably possible or remote. In July 2021, Legacy Archaea settled certain lawsuits on confidential terms with the lawsuits being dismissed with prejudice.

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

NOTE 1 - Description of Business - Predecessor

Aria Energy LLC and its subsidiaries ("Aria") design, install, own, and operate long-lived energy projects. Aria was originally formed on September 6, 2007, as EIF Renewable Energy Holdings LLC, a Delaware LLC, headquartered in Novi, Michigan. Aria generates its revenue from customers located throughout the United States from the production and sale of electrical energy from landfill gas fuel engines and related Environmental Attributes, production and sale of RNG and related Environmental Attributes, operating and maintaining landfill gas projects owned by third parties, and constructing energy projects.

Revenue is generated from the sale of commodities (power and gas), sale of capacity (power market) and from the sale of Environmental Attributes, including RECs in the power market and RINs and LCFS credits in the RNG market.

Aria benefits from Federal and state renewable fuel standards and Federal compliance requirements for landfill owners and operators.

Funds managed by Ares EIF Management LLC held 94.35% of the ownership interests in Aria before the Closing of the Business Combinations.

The accompanying consolidated financial statements present the consolidated financial position and results of operations of Aria Energy LLC and its wholly owned subsidiaries.

The impact of the pandemic caused by the novel coronavirus (“COVID-19”) and measures to prevent its spread have been impactful and continue to affect Aria's business in several ways. In March of 2020, Aria implemented a COVID-19 response team, led by senior management, which initially met on a daily basis to report health status and develop guidelines to protect our workforce. Daily health monitoring and internal contact tracing protocols were implemented. The response team sought feedback from employees, particularly those working in our plants, in developing policies and protocols. Work-from-home protocols were implemented immediately where possible for non-operations personnel. For on-site employees, PPE was provided and enhanced hygiene and physical distancing protocols were implemented. The necessary IT improvements were initiated to facilitate a remote work environment, and we leveraged supplier networks to source COVID-19 specific PPE. Communications from senior leadership to all employees were enhanced, with weekly updates provided. Through the Closing Date, Aria has not experienced any spread of the disease within its operating and management locations or any material interruptions to its business operations.

NOTE 2 - Summary of Significant Accounting Policies - Predecessor

Basis of Presentation

The consolidated financial statements of Aria have been prepared on the basis of United States generally accepted accounting principles ("US GAAP").

Segment Reporting

Aria reports segment information in two segments: RNG and electric operations (Power). Landfill gas fuel source is a common element, though Aria had a new RNG plant that was under construction as of Closing Date that will utilize waste from dairy cattle. Aria managed RNG and electric production as separate operating groups and measured production output in terms of megawatt hours (MWh) for Power projects, and energy content is expressed as MMBtu for RNG. Other segment reporting considerations include:

•There are separate operating and leadership teams for RNG and Power, each of whom have different skill sets. The processes for production are unique.

•Customers are different. Utilities and ISO’s are buyers of electricity and RECs. Municipalities and energy companies are the primary buyers of RNG and RINs.

42

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

•Economics are much stronger with RNG. Prices for both segments are volatile, but based on different drivers.

•Aria operates a small portfolio of Power plants for third parties. Operationally these plants are the same as wholly-owned projects.

•Aria operates RNG plants for its joint venture (JV) Mavrix LLC ("Mavrix"). These plants are operationally the same as wholly-owned plants.

•Construction activity is limited to wholly owned or JV plants. No construction activity is performed for third parties. Construction revenue only exists when building assets for non-consolidated subsidiaries.

Use of Estimates

The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Actual results could differ from those estimates.

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 ("LESPH").

Revenue Recognition

Aria 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 US GAAP, a portion of revenue is accounted for under Accounting Standards Codification ("ASC") 840, Leases, and a portion under ASC 606, Revenue from Contracts with Customers. Under ASC 840, revenue is recognized generally upon delivery of electricity, gas, and their related renewable Environmental Attributes. Under ASC 606, revenue is recognized upon the transfer of control of promised goods or services to the customer in an amount that reflects the consideration to which is expected to be entitled in exchange for those goods or services. Based on the terms of the power purchase agreements ("PPAs"), the amounts recorded under ASC 840 are generally consistent with revenue recognized under ASC 606. For the year-to-date period ended September 14, 2021, approximately 36% of revenue was accounted for under ASC 606 and 64% under ASC 840. For the nine months ended September 30, 2020, approximately 42% of revenue was accounted for under ASC 606 and 58% under ASC 840.

The following tables display Aria’s revenue by major source and by operating segment for the periods July 1 to September 14, 2021 and January 1 to September 14, 2021 and the three and nine months ended September 30, 2020:

Below is a description of accounting policies for each revenue stream:

Electricity

Aria 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. Aria 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 Aria’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 market. These electricity generation revenue streams are accounted for under ASC 606. These electric revenue streams are 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. Aria also sells its capacity into the month-ahead and three-year ahead markets in the wholesale markets to satisfy system integrity and reliability requirements. Revenue from capacity is recognized under ASC 606 over time using an output method. Capacity, which is a stand-ready obligation to deliver energy when required by the customer, is measured using MWs of capacity.

Gas

Aria 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.

Aria 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.

44

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Environmental Attributes

Aria also generates revenue through the sale of Environmental Attributes, which is included in energy revenue. Aria’s electric plants generate renewable energy credits, or RECs, as they generate electricity. The majority of Aria’s RECs are generated by plants for which Aria 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, revenue is recognized under ASC 606 at a point-in-time, when control is transferred. For RECs subject to sales agreements prior to energy generated, control is deemed to be transferred and revenue recognized when related energy is generated even in cases where there is a certification lag as it has been deemed to be perfunctory.

Aria generates renewable fuel credits called renewable identification numbers, or RINs. Pipeline-quality renewable natural gas processed from landfill gas qualifies for RINs when delivered to a compressed natural gas fueling station. RINs are similar to RECs on the electric side in that they reflect the value of renewable energy as a means to satisfy regulatory requirements or goals. They are different in that RINs exist pursuant to a national program and not an individual state program. The majority of Aria’s RINs are generated by plants for which Aria has a PPA to sell all of the outputs and are therefore accounted for as operating leases in accordance with ASC 840, with revenue recognized when the fuel is produced and transferred to a third party.

Construction Type Contracts

Aria, 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.

Operation and Maintenance (O&M)

Aria provides O&M services at projects owned by third parties which are included in Energy revenue on Aria's Condensed Consolidated Statement of Operations. 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 or RNG from the project.

PPA and O&M Contract Amortization

Through historical acquisitions, Aria had both above and below-market contracts from PPAs and O&M agreements related to the sale of electricity or delivery of services in future periods for which the fair value has been determined to be more or less than market. The amount above and below-market value is being amortized to revenue over the remaining life of the underlying contract which is included in Energy revenue on Aria's Condensed Consolidated Statement of Operations.

Aria elected to recognize revenue using the right to invoice practical expedient and determined that the amounts invoiced to customers correspond directly with the value to customers and Aria’s satisfaction of the performance obligations to date. Furthermore, with the election of the right to invoice practical expedient, Aria also elects to omit disclosures on the remaining, or unsatisfied performance obligations since the revenue recognized corresponds to the amount that Aria has the right to invoice.

Cash and Cash Equivalents

Aria considers all investments with an original maturity of three months or less when purchased to be cash equivalents. Aria maintains amounts on deposit with various financial institutions, which may exceed federally insured limits. Management periodically evaluates the creditworthiness of those institutions. Aria had not experienced any losses on such deposits.

45

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

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 September 14, 2021 and December 31, 2020 based on Aria’s history with its existing customers. Payments on accounts receivable balances are typically due and paid within 30 days of invoice.

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.

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 Aria 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 Aria’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 year-to-date periods ended September 14, 2021 and September 30, 2020.

Depreciation is computed using the straight-line method over the estimated useful lives of the assets.

Held for Sale

During 2020, Aria enacted a plan to sell 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 $58.5 million, which were sent to the lenders of the LESPH debt discussed in Note 6. As discussed further in Note 6, in connection with the sale, Aria was released from its obligations under the LESPH debt and a gain on the extinguishment of debt in the amount of $61.4 million was recorded in conjunction with the sale, which accounts for the proceeds received, the debt and interest payable relieved and settlement of LESPH intercompany balances. Aria recorded an ordinary gain on sale of assets in the amount of $1.3 million.

The pre-tax net earnings (losses) associated with LEPSH, including the gain on extinguishment of debt and ordinary gain on sale of assets recognized in 2021, included in Aria’s consolidated condensed statement of operations were $67.6 million and $(9.6) million for the year-to-date periods ended September 14, 2021 and September 30, 2020, respectively, of which $67.3 million and $(9.5) million, respectively, were attributable to Aria.

Impairment of Long-Lived Assets

In accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), property and equipment, 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.

For purposes of testing for an impairment loss, a long-lived asset or assets shall be grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The lowest level of cash inflows and outflows largely independent of other assets is generally determined to be a project,

46

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

which represents a single electrical or gas generation facility located at a single landfill site. 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).

There were no triggering events related to Aria’s projects in the period ended September 14, 2021.

Other Noncurrent Assets

The other noncurrent assets as of December 31, 2020 represents long-term deposits with transportation and utility companies.

Debt Origination Costs

Debt origination costs were incurred 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 debt.

Equity Method Investments

Aria's investments in joint ventures are reported under the equity method. Under this method, Aria records its proportional share of its income or losses of joint ventures as equity investment income, net in the consolidated statements of operations.

Derivative Instruments

Aria 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 were recognized in earnings.

Asset Retirement Obligations

Asset retirement obligations ("AROs") associated with long-lived assets are those for which a legal obligation exists under enacted laws, statutes, and written or oral contracts and for which the timing and/or method of settlement may be conditional on a future event. AROs are recognized at fair value in the period in which they are incurred and a reasonable estimate of fair value can be made. Upon initial recognition of an obligation, Aria capitalizes the asset retirement cost by increasing the carrying amount of the related long-lived asset by the same amount. Over time, the liability is accreted to its expected future value, while the capitalized cost is depreciated over the useful life of the related asset. Accretion expense is included in depreciation, amortization and accretion in the consolidated statements of operations. See note 10 for further disclosures on AROs.

Postretirement Obligations

Postretirement benefits amounts recognized in consolidated financial statements are determined on an actuarial basis. Aria 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 8 for further disclosures on postretirement obligations.

Other Long-Term Liabilities

Other long-term liabilities are recognized in the consolidated financial statements as obligations of Aria that are due more than one year in the future. Based on a contractual obligation under its Mavrix LLC (Mavrix) operating agreement (as discussed in Note 5), as of September 14, 2021 and December 31, 2020, Aria estimates an earn-out related to the

47

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

performance of the Mavrix joint ventures payable in 2022 in the amount of $1.7 million and $1.4 million, respectively. The maximum earn-out under the operating agreement is $9.55 million.

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 Aria’s postretirement plan.

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.

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 September 14, 2021 and December 31, 2020 recorded against its net deferred tax asset. The entity has recorded no income tax expense for the year-to-date period ended September 14, 2021 and September 30, 2020.

Concentration of Credit Risk

Financial instruments which potentially subject Aria 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 Aria’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, Aria believes that the credit risk posed by industry concentration is offset by the creditworthiness of its customer base.

Cost of Energy

Cost of energy consists primarily of labor, parts, and outside services required to operate and maintain 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.

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.

Aria 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 debt, the carrying amounts approximate fair value as the interest rates obtained by Aria approximate the prevailing interest rates available to Aria for similar instruments.

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:

48

ARIA ENERGY LLC AND SUBSIDIARIES (Predecessor)

NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the entity 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. Aria’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

Intangible assets consist of gas rights agreements, operations and maintenance contracts, power purchase, gas sales and gas purchase agreements that were created as a result of the allocation of the purchase price under business acquisitions based on the future value to Aria and amortized over their estimated useful lives. The gas rights agreements have various renewal terms in their underlying contracts that are factored into the useful lives when amortizing the intangible asset.

For intangibles and below-market contracts, depreciation, amortization and accretion was $7.4 million and $12.2 million for the periods ended September 14, 2021 and September 30, 2020, respectively. Below-market contracts related to the purchase of gas are amortized to cost of energy, and amortization was $1.8 million for both the periods ended September 14, 2021 and September 30, 2020, which was recorded as a decrease to cost of energy.

NOTE 5 - Equity Method Investments - Predecessor

Aria holds 50% interests in two joint ventures accounted for using the equity method – Mavrix and Sunshine Gas Producers, LLC. Prior to the sale of LESPH in June 2021, Aria also held 50% interests in the following four joint ventures: Riverview Energy Systems, LLC, Adrian Energy Systems, LLC, Salem Energy Systems, LLC and Salt Lake Energy Systems LLC. See Held for Sale section in Note 2 for more discussion on the sale of LESPH.

Under the terms of the Mavrix LLC Contribution Agreement dated September 30, 2017, Aria is required to make an earn-out payment to its JV partner holding the other 50% membership (in Mavrix LLC) in an amount up to $9.55 million. As defined in the Contribution Agreement, the payment represents additional consideration for Aria’s equity interest in Mavrix, and the earn-out payment will be based on the performance of certain projects owned by Mavrix through the earn-out period which ends September 30, 2022. No earn-out payment is made until after the end of the earn-out period. Aria has estimated the earn-out payment to be $1.7 million at September 14, 2021 and $1.4 million at December 31, 2020, and has recorded these amounts in other long-term liabilities in the respective periods.

Notes Payable

In October 2010, LESPH entered into a credit agreement with a syndicate of bank lenders (the Banks) that provided for a term note and a working capital commitment (Line of Credit) which is described below. The term note, along with working capital commitment, is collateralized exclusively by the assets of LESPH, and is nonrecourse to Aria Energy LLC. In accordance with the associated credit agreement, the above notes payable were due October 7, 2020, but were unpaid as of December 31, 2020.

Aria enacted a plan to sell LESPH in 2020. On March 1, 2021, Aria entered into a Membership Interest Purchase Agreement (MIPA) for the purpose of selling 100% of the membership interests in LESPH. In accordance with Section 4.02 of the MIPA, the Sellers obligations at closing include the execution of the Lender Release, as defined in the agreement, releasing of Liens and claims with respect to LESPH and its consolidated and non-consolidated subsidiaries, terminating the LESPH credit agreement and discharging the borrowers’ obligations.

The sale of LESPH occurred on June 10, 2021 and the extinguishment of the debt resulted in a gain being recorded equal to the difference between the reacquisition price and the net carrying amount of the debt of $122.6 million ($102.8 million in principal, $19.8 million in unpaid interest). This gain is classified as part of nonoperating income on the Statement of Operations.

Senior Secured Credit Facility Revolver and Term Loan B

Aria Energy LLC and certain subsidiaries (Borrowers) entered into a senior secured credit facility that provides for a $200 million secured term loan, and a $40.2 million secured revolving credit facility, of which $40.0 million can be used for letters of credit. During 2020, the revolving credit maturity date was extended until November 24, 2021. The facility is secured by a first lien security interest in the assets of the Borrowers. Payments on the term loan were due in quarterly installments of $0.5 million that began on September 30, 2015 and continued until the debt was retired as part of the Business Combinations.

NOTE 7 - Derivative Instruments - Predecessor

Aria was 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.

Aria has a natural gas variable to fixed priced swap agreement with a remaining notional quantity of 789,600 MMBtu as of December 31, 2020. 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 derivative contracts 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 (a Level 2 measurement), with an adjustment for each counterparty's credit rate risk.

On April 6, 2020 Aria entered into an interest rate cap with a total notional amount of $110 million and an effective date of April 30, 2020. The cap agreement provides a fixed cap rate of 1.00% per annum related to the one-month LIBOR and has a termination date of May 31, 2022. The market value at both September 14, 2021 and December 31, 2020 was valued at zero and all associated fees with this transaction were recorded. Aria made cash payments for the natural gas swap of $0.5 million and $1.1 million for the period January 1 to September 14, 2021 and for the nine months ended September 30, 2020 respectively.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements reflecting our current expectations, estimates, and assumptions concerning events and financial trends that may affect our future operating results or financial position. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in the sections entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" appearing elsewhere in this Quarterly Report.

Overview

Archaea is one of the largest RNG producers in the U.S., with an industry-leading RNG platform primarily focused on capturing and converting waste emissions from landfills and anaerobic digesters into low-carbon RNG and electricity. Biogas is produced by single-celled organisms called archaea which break down organic matter in the absence of oxygen during a process called anaerobic digestion. As of September 30, 2021, the Company owns and/or operates a diversified portfolio of 23 LFG recovery and processing projects across 12 states, including 13 LFG to electric projects and 10 projects that produce pipeline-quality RNG. See “ – Our Projects” for additional detail.

Archaea designs, constructs, and operates RNG facilities. Archaea's development portfolio includes over 30 cumulative projects as of September 30, 2021. We intend to upgrade certain operating RNG facilities over time, we are exploring opportunities to convert a majority of our renewable electricity facilities into RNG facilities when economically accretive, and we intend to develop and construct the greenfield development opportunities for which we have gas rights agreements. We are also planning to secure additional RNG development opportunities through long-term agreements with biogas site hosts, and we are evaluating other potential sources of biogas, developing wells for carbon sequestration, and exploring the use of on-site solar-generated electricity to meet energy needs for RNG production.

Our differentiated commercial strategy is focused on selling the majority of our RNG volumes under long-term, fixed-price contracts to creditworthy partners, helping entities decarbonize while utilizing their existing gas infrastructure. RNG and renewable electricity generate valuable Environmental Attributes that are able to be monetized under international, federal, and state initiatives. Whenever possible, the Company seeks to mitigate exposure to commodity and Environmental Attribute pricing volatility by selling our RNG and related Environmental Attributes under long-term contracts which are designed to provide revenue certainty.

RNG has the same chemical composition as traditional natural gas from fossil sources, and the RNG we produce is pipeline-quality and can be used interchangeably with natural gas in any application.

The Business Combinations and Related Transactions

On April 7, 2021, RAC entered into the Aria Merger Agreement and the Archaea Merger Agreement (together with the Aria Merger Agreement, the "Business Combination Agreements"). On September 15, 2021 (the "Closing Date"), RAC completed the Business Combinations to acquire Legacy Archaea and Aria. Following the Business Combinations closing, RAC changed its name from "Rice Acquisition Corp." to "Archaea Energy Inc.," also referred to herein as the "Company." Rice Acquisitions Holdings LLC (RAC Opco) was renamed LFG Acquisition Holdings LLC (“Opco”). In connection with the Business Combinations closing, the Company completed a private placement of 29,166,667 shares of Class A Common Stock for gross proceeds of $300 million.

The Company issued 33.4 million Opco Class A units and 33.4 million shares of Class B Common Stock at the Closing Date to Legacy Archaea Holders to acquire Legacy Archaea. Aria was acquired for total initial consideration of $863.1 million, subject to certain future adjustments set forth in the Aria Merger Agreement (the “Aria Closing Merger Consideration”). The Aria Closing Merger Consideration paid to Aria Holders consisted of cash consideration of $377.1 million and equity consideration in the form of 23.0 million newly issued Opco Class A units and 23.0 million newly issued shares of the Company's Class B Common Stock, par value $0.0001 per share.

Archaea has retained its “up-C” structure, whereby all of the equity interests in Aria and Legacy Archaea are indirectly held by Opco and Archaea’s only assets are its equity interests in Opco.

55

The Up-C structure allows the Legacy Archaea Holders, the Aria Holders and the Sponsor to retain their equity ownership through Opco, an entity that is classified as a partnership for U.S. federal income tax purposes, in the form of Opco Class A Units, and provides potential future tax benefits for Archaea when those holders of Opco Class A Units ultimately exchange their Opco Class A Units and shares of the Company’s Class B Common Stock for shares of Class A Common Stock in the Company. Opco is considered a VIE for accounting purposes, and the Company, as the sole managing member of Opco, is considered the primary beneficiary. As such, the Company consolidates Opco, and the unitholders that hold economic interest directly at Opco are presented as redeemable noncontrolling interests in the Company's financial statements.

Predecessor and Successor Reporting

Legacy Archaea is considered the accounting acquirer of the Business Combinations for accounting purposes because Legacy Archaea Holders have the largest portion of the voting power of the combined company, Legacy Archaea's executive management comprise the majority of the executive management of the combined company, and the Legacy Archaea Holders appointed the majority of board members exclusive of the independent board members. The Archaea Merger represents a reverse merger and is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, RAC is treated as the "acquired" company for financial reporting purposes. Accordingly, for accounting purposes, the Archaea Merger is treated as the equivalent of Legacy Archaea issuing shares for the net assets of RAC, accompanied by a recapitalization. The net assets of RAC are stated at historical cost. No goodwill or other intangible assets are recorded. Legacy Archaea is also considered the "Successor". As such, the consolidated assets, liabilities and results of operations prior to the September 15, 2021 reverse recapitalization are those of Legacy Archaea, the accounting acquirer. The consolidated condensed financial statements include the assets, liabilities and results of operations of the Company and its consolidated subsidiaries beginning on September 15, 2021, which includes 16 days of the combined results of the businesses of Legacy Archaea and Aria as operated by the Company after the Business Combination.

The Aria Merger represents an acquisition of a business, and Aria's identifiable assets acquired and liabilities assumed are measured at their acquisition date fair value. Due to Aria's historical operations compared to Legacy Archaea and the relative fair values, Aria was determined to be the "Predecessor". As Predecessor, Aria's historical financial statements have been included to enhance comparability for readers, and we have also included a discussion of the Aria’s operations, financial condition and changes in financial condition for the three and nine months ended September 30, 2021 and 2020, in addition to a discussion of the operations of both Legacy Archaea and Aria from September 15, 2021 through September 30, 2021 for the three and nine months ended September 30, 2021 compared to Aria results for the three and nine months ended September 30, 2020.

Factors Affecting the Comparability of Our Financial Results

Our future results of operations will not be comparable to our Successor or our Predecessor’s historical results of operations for the reasons described below:

•The Company's future results of operations and financial position may not be comparable to Legacy Archaea's or Aria’s historical results as a result of the Business Combinations and the Company's ongoing development activities. Our results prior to the closing of the Business Combinations on September 15, 2021 only include Legacy Archaea, the accounting acquirer, whereas our results beginning on September 15, 2021 include the combined operations of Legacy Archaea and Aria as managed by the Company. In addition, both Legacy Archaea and Aria have experienced significant growth and expansion over the last two years.

•Legacy Archaea was formed in November of 2018 and did not have significant assets, liabilities or operations until its acquisition of BioFuels San Bernardino Biogas, LLC in September of 2019, to acquire the landfill gas rights agreements with two landfills located in San Bernardino County, California. Subsequent to this acquisition, Legacy Archaea purchased a 72.2% controlling interest in Gulf Coast Environmental Systems, an original equipment manufacturer of air, water, and soil remediation pollution control systems, in February 2020, and purchased 100% of the outstanding membership interests in PEI Power LLC, a biogas fuel combustion power generating facility in April 2021.

•As a consequence of the Business Combinations, the Company has hired and will need to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. The Company expects to incur additional annual expenses as a public company that Legacy

56

Archaea did not historically incur to date for, among other things, directors' and officers' liability insurance, director fees and additional internal and external accounting and legal and administrative resources, including increased audit and legal fees.

•There are differences in the way the Company will finance its operations as compared to the way our Successor or Predecessor financed its operations. The Company received approximately $175 million in net proceeds from the Business Combinations, the PIPE Financing, and debt issuance after payment of the Aria Merger cash consideration and transaction expenses to fund the Company’s future growth projects. Upon consummation of the Business Combination, Archaea Energy Operating LLC (“Archaea Borrower”), entered into a $470 million Revolving Credit and Term Loan Agreement (the “New Credit Agreement”) which provides for a senior secured revolving credit facility (the “Revolver”) with an initial commitment of $250 million and a senior secured term loan credit facility (the “Term Loan” and, together with the Revolver, the “Facilities”) with an initial commitment of $220 million. At the Closing, Archaea Borrower has an outstanding principal balance of approximately $220 million outstanding under the Term Loan, and Archaea Borrower has not drawn on the Revolver but had outstanding letters of credit of approximately $15.8 million.

•As a corporation, Archaea will be subject to federal taxes in the future to the extent the Company generates positive taxable income.

Other Significant Acquisitions

Boyd County Project (Big Run)

On November 10, 2020, Legacy Archaea acquired all the outstanding membership interests of a high-Btu facility that had not previously been properly commissioned to process landfill gas to pipeline specification renewable natural gas in Ashland, Kentucky. In April 2021, the facility commenced commercial operations. It continues to ramp up production.

Project Assai and PEI

On January 6, 2020, Legacy Archaea began the development of its Assai biogas project on the site of the Keystone Sanitary Landfill in Dunmore, Pennsylvania, in the Scranton metro area. Project Assai is the world's largest RNG plant currently under construction and, upon completion, is expected to be the largest LFG-to-RNG facility in the world. Archaea expects Project Assai to commence initial operations in the first quarter of 2022, with production scaling up over time thereafter.

On April 7, 2021, Legacy Archaea completed the acquisition of PEI. PEI's assets include landfill gas rights, a pipeline, and a biogas fuel combustion power generating facility with a combined capacity of approximately 85 MW located in Archbald, Pennsylvania. We intend to transport landfill gas from PEI to Assai in the future.

GCES

On January 14, 2020, Legacy Archaea purchased a controlling position 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. GCES manufactures equipment that will be used in the Company's RNG projects in addition to selling equipment to third parties.

Our Projects

Archaea has a base of operational assets today and a robust pipeline of RNG development opportunities. As of September 30, 2021, we own and operate 23 projects, 10 of which are RNG projects and 13 of which are renewable electricity (“Power”) projects. Prior to the consummation of the Business Combinations, the RNG projects were included in Archaea’s or Aria’s RNG operating segment, and the Renewable Electricity projects were included in Aria’s Power operating segment, except for the PEI Power project in Archbald, PA, which was included in Archaea’s Power operating segment. Over the next several years, we intend to convert certain current LFG-to-electricity projects to RNG projects and upgrade certain existing RNG projects. These facilities already have gas development agreements in place in addition to site leases, zoning, air permits, and much of the critical infrastructure that is needed to develop RNG projects. We also plan to develop and construct our portfolio of greenfield development opportunities, for which we also already have gas development agreements in place. Our development portfolio as of September 30, 2021 includes over 30 cumulative

57

upgrade, conversion, and greenfield projects, and we are planning to secure additional RNG development opportunities through long-term agreements with biogas site hosts.

Key Factors Affecting Operating Results

The Company's performance and future success depend on several factors that present significant opportunities but also pose risks and challenges, including those discussed below and in the section of Archaea's most recently filed registration statement entitled "Risk Factors."

Successful Development and Operation of Projects

The Company's business strategy includes growth primarily through the upgrade and expansion of existing RNG projects, conversion of landfill gas to electric projects to RNG projects, development and construction of greenfield RNG development projects for which we already have gas development agreements in place, and the procurement of landfill gas rights to develop additional greenfield RNG projects. The Company is actively considering expansion into other lines of business, including anaerobic digesters, carbon sequestration, and producing on-site renewable electricity for our projects.

Until commercial RNG operations commenced in the fiscal quarter ended June 30, 2021, Legacy Archaea’s revenues were derived primarily from the sale of customized pollution control systems to third-party customers. With the acquisition of Aria and as our RNG and other projects continue to become commercially operational, the Company expects that a majority of our revenues will be generated from the sale of RNG and renewable electricity, primarily under long-term off-take agreements, along with the Environmental Attributes that are derived from these products. Following the Business

58

Combinations, until the Company can generate sufficient revenue from RNG, renewable electricity and Environmental Attributes, the Company is expected to primarily finance its project development activities with its existing cash and financing arrangements currently in place. See "Liquidity and Capital Resources - New Credit Facility," for further discussion of our existing financing arrangements. The amount and timing of the future funding requirements will depend on many factors, including the pace and results of our acquisitions and project development efforts.

Market Trends and Exposure to Market-Based Pricing Fluctuations

Future revenues will depend to a substantial degree upon the demand for RNG, renewable electricity and Environmental Attributes, all of which are affected by a number of factors outside our control. To manage exposure to market-based pricing fluctuations, the Company will sell RNG primarily under long-term off-take agreements with fixed pricing to counterparties with strong credit profiles. Archaea's goal is to contract a majority of our RNG volumes under long-term fixed price off-take agreements. The credit profiles of the buyers of RNG are subject to change and are outside our control. Future expenses will depend to a substantial degree upon electricity prices and the costs of raw materials and labor. These costs, too, are subject to a number of factors outside our control.

Regulatory Landscape

We operate in an industry that is subject to and currently benefits from environmental regulations. Government policies can increase the demand for our products by providing market participants with incentives to purchase RNG, renewable electricity and Environmental Attributes. These government policies are continuously being modified, and adverse changes in such policies could have the effect of reducing the demand for our products. Government regulations applicable to our renewable energy projects have generally become more stringent over time. Complying with any new government regulations may result in significant additional expenses or related development costs for us.

Seasonality

Revenues generated from our power projects in the northeast United States, all of which sell electricity at market prices, are affected by warmer and colder weather, and therefore a portion of our quarterly operating results and cash flows are affected by pricing changes due to regional temperatures. Our energy production can also be affected during the summer months, as very warm temperatures can dry out a landfill if the landfill owner is unable to keep the landfill covered, which in turn reduces the landfill gas generated at the site. The weather during colder months affects power pricing and revenues due to the direct effect of natural gas pricing in the northeastern United States and its effect on supply during these months. These seasonal variances are managed in part by our current and expected future long-term off-take agreements at fixed prices.

Impacts of COVID-19

To date, the COVID-19 pandemic and preventative measures taken to contain or mitigate the pandemic have caused, and are continuing to cause, business slowdowns or shutdowns in affected areas and significant disruptions in the financial markets both globally and in the United States.

In response to the COVID-19 pandemic and related mitigation measures, the Company began implementing changes in its business in March 2020 to protect its employees and customers, and to support appropriate health and safety protocols. These measures resulted in additional costs, which we expect will continue through 2021 as we continue to work to address employee safety. As of the date of this Quarterly Report, such business changes and additional costs have not been, individually or in the aggregate, material to us. We are considered an essential company under the U.S. Federal Cybersecurity and Infrastructure Security Agency guidance and the various state or local jurisdictions in which we operate.

Certain third parties with whom we engage, including project partners, third-party manufacturers and suppliers, and regulators with whom we conduct business, have adjusted their operations and are assessing future operational and project needs in light of the COVID-19 pandemic. If these third parties experience shutdowns or continued business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and adversely affected. The pandemic could also cause disruptions in our supply chain due to transportation delays, travel restrictions, raw material cost increases, and shortages and closures of businesses or facilities. It may also cause delays in construction and other capital expenditures at our projects, obtaining regulatory approvals, and collecting our receivables for our products and services.

59

The duration and extent of the impact from the COVID-19 pandemic depend on future developments that cannot be accurately predicted at this time, such as the severity and transmission rate of the virus and related variants, the extent and effectiveness of containment actions and the impact of these and other factors on our employees, customers, suppliers, and distributors.

Results of Operations

Basis of Presentation

Our revenues are generated from the production and sale of RNG and renewable electricity, along with the Environmental Attributes that we are able to derive from these products. RNG has the same chemical composition as natural gas from fossil sources, but has unique Environmental Attributes associated with it due to its origination from low-carbon, renewable sources, and we are able to monetize these attributes. The RNG we process is pipeline-quality and can be used interchangeably with natural gas in any application and existing gas infrastructure. The Environmental Attributes that we sell are composed of RINs and state low-carbon fuel credits, which are generated from use of RNG as a transportation fuel, as well as from RECs generated from the conversion of biogas to renewable electricity. In addition to revenues generated from our product sales, we also generate revenues by providing O&M services to certain of our project and biogas site partners.

The Company reports segment information in two segments: RNG and renewable electricity generation ("Power"). Prior to the Business Combinations, the Company managed RNG as its primary business operations, which is to construct and develop biogas facilities on landfill sites for conversion to RNG. Our Power segment generates revenue by selling renewable electricity and associated Environmental Attributes. In addition, we hold interests in other entities that are accounted for using the equity method of accounting, including Mavrix, which owns and operates four separate RNG facilities included in the RNG segment, and the Sunshine electric project included in the Power segment. We expect our future growth to be driven primarily by additional projects within the RNG segment and we expect to convert the majority of our landfill gas to electric projects to RNG projects over time.

Key Metrics

Management regularly reviews a number of operating metrics and financial measurements to evaluate our performance, measure our growth and make strategic decisions. In addition to traditional GAAP performance and liquidity measures, such as revenue, cost of revenue, net income and cash provided by operating activities, we also consider MWh and MMBtu sold, and Adjusted EBITDA in evaluating our operating performance. Each of these metrics is discussed below.

Key Components of Results of Operations

As a result of the Business Combinations, prior year amounts are not comparable to current year amounts or expected future trends. The historical financial statements included herein are the financial statements of Legacy Archaea for three months and nine months ended September 30, 2020.

Revenue

The Company generates revenues from the production and sales of RNG, Power, renewable energy Environmental Attributes, as well as the performance of other landfill energy operations and maintenance (“O&M”) services. The Company manufactures customized pollution control equipment and performs associated maintenance agreement services. Whenever possible, we seek to mitigate our exposure to commodity and Environmental Attribute pricing volatility. We seek to sell a significant portion of our RNG production volumes under long-term, fixed-price arrangements with creditworthy partners. We sell a portion of our volumes under short-term agreements, and many of these volumes generate Environmental Attributes which we also monetize.

Until commercial RNG operations for Legacy Archaea commenced in the fiscal quarter ended June 30, 2021, revenues were historically comprised of sales of customized pollution control equipment and maintenance agreement services. Revenues in Legacy Archaea's RNG segment commenced in the second quarter of 2021 with commercial operations at our Boyd County facility, and increased in the third quarter of 2021 due to the Business Combinations and the inclusion of Aria for 16 days in the Company’s results. Revenues in our REG segment commenced with the PEI acquisition in the second quarter of 2021, and increased in the third quarter of 2021 due to the Business Combinations and the inclusion of Aria for 16 days in the Company’s results.

60

Cost of operations

Cost of operations is comprised primarily of labor, parts and outside services required to operate and maintain equipment utilized in generating energy from our owned project facilities and from our landfill sources. Other costs directly related to the production of electricity and RNG are transportation costs associated with moving gas into pipelines, transmission costs of moving power between the ISOs, electricity consumed in the process of gas production, and royalty payments to landfill owners as stipulated in our gas rights agreements. Our payments to biogas site hosts are primarily in the form of royalties based on realized revenues or, in some select cases, based on production volumes.

Prior to the Business Combinations, cost of operations was historically comprised primarily of personnel compensation and benefits, insurance and raw materials, and parts and components for manufacturing equipment for sale.

Environmental Attributes are a form of government incentive and not a result of the physical attributes of the biogas or electricity production. Therefore, no cost is allocated to the Environmental Attribute when it is generated, regardless of whether it is transferred with the biogas or electricity produced or held by the Company. Additionally, Environmental Attributes, once obtained through the production and sale of biogas or electricity, may be separated and sold separately.

Cost of operations also includes depreciation, amortization, and accretion expense on our power and gas processing plants, amortization of intangible assets relating to our gas and power rights agreements, and the accretion of our asset retirement obligations. Depreciation and amortization is recognized using the straight-line method over the underlying assets' useful life. Accretion expense is recognized based on the effective yield method.

General and administrative expenses

General and administrative expenses consist primarily of personnel-related costs (including salaries, bonuses, benefits, and share-based compensation) for our executive, finance, human resource, and administrative departments and fees for third-party professional services, including consulting, legal and accounting services. In addition, we allocate a portion of overhead costs, including leasing expenses, utilities, and worker's compensation premiums, to the general and administrative expenses based on headcount. No depreciation or amortization expenses are allocated to general and administrative expenses.

We expect our general and administrative expenses to increase for the foreseeable future as we scale headcount with the growth of our business, and as a result of operating as a public company, including compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations activities and other administrative and professional services.

Equity earnings

We hold interests in other entities that are accounted for using the equity method of accounting, including Mavrix, which owns and operates four separate RNG facilities, and the Sunshine electric project.

Successor Comparison of the Three and Nine Months Ended September 30, 2021 and 2020

The following discussion pertains to our results of operations, financial condition, and changes in financial condition of the Successor, which includes only Legacy Archaea for dates prior to September 15, 2021 and the operations of both Legacy Archaea and Aria from September 15, 2021 through September 30, 2021. Any increases or decreases "for the three months ended September 30, 2021" refer to the comparison of the three months ended September 30, 2021, to the three months ended September 30, 2020, and any increases or decreases "for the nine months ended September 30, 2021" refer to the comparison of the nine months ended September 30, 2021, to the nine months ended September 30, 2020.

In 2020, Legacy Archaea did not have operational assets and as such, the Power and RNG segments did not exist. As such, any segment comparison would not be informative and has not been included for comparison purposes.

Set forth below is a summary of volumes sold for the three and nine months ended September 30, 2021 and 2020.

	Three Months Ended September 30,		Nine Months Ended September 30,
	2021	2020	2021	2020
RNG sold (MMBtu)	320,265	—	378,730	—
Electricity sold (MWh)	77,228	—	164,307	—

Volumes increased in 2021 compared to 2020 due to the commencement of commercial operations in April 2021 at our Boyd County facility, the purchase of the PEI power assets in April 2021, and the acquisition of Aria.

Set forth below is a summary of selected financial information for the three and nine months ended September 30, 2021 and 2020:

	Three Months Ended September 30,						Nine Months Ended September 30,
(in thousands)	2021		2020		$ Change		2021		2020		$ Change

Revenues

Revenue increased for the three month period ended September 30, 2021 due to the commencement of commercial operations in April 2021 at our Boyd County facility, the purchase of the PEI power assets, and the acquisition of Aria, offset by a reduction of GCES third-party sales.

Revenue increased for the nine month period ended September 30, 2021 due to the commencement of commercial operations in April 2021 at our Boyd County facility, the purchase of the PEI power assets, and the acquisition of Aria, offset by a reduction of GCES third-party sales.

Cost of Operations

Costs of operations increased for the three month period ended September 30, 2021 due to the commencement of commercial operations in April 2021 at our Boyd County facility, the purchase of the PEI power assets, and the acquisition of Aria, offset by a reduction of GCES costs associated with reduced third-party sales.

Costs of operations increased for the nine month period ended September 30, 2021 due to the commencement of commercial operations in April 2021 at our Boyd County facility, and the purchase of the PEI power assets, and the acquisition of Aria.

General and Administrative Expenses

General and administrative expenses increased for the three and nine month periods ended September 30, 2021 due to merger related expenses related to additional legal costs, contractors and consultants, additional general and administrative staff as our business has expanded, and stock compensation expense.

Other Income (Expense)

Other income (expense) increased primarily attributed to the increase in fair value of the warrant liabilities from the date of the Business Combinations through September 30, 2021 resulting in a loss of $10.4 million.

Adjusted EBITDA

62

Adjusted EBITDA is calculated by taking net income (loss) attributable to Class A Common Stock, before taxes, interest expense, and depreciation, amortization and accretion, and adjusting for the effects of certain non-cash items, other non-operating income or expense items, and other items not otherwise predictive or indicative of ongoing operating performance, including gains and losses on disposal of assets, impairment charges, debt forbearance costs, changes in the fair value of derivatives, non-cash compensation expense, and non-recurring costs related to our business combinations. We believe the exclusion of these items enables investors and other users of our financial information to assess our sequential and year-over-year performance and operating trends on a more comparable basis and is consistent with management’s own evaluation of performance.

Adjusted EBITDA is commonly used as a supplemental financial measure by our management and external users of our consolidated financial statements to assess the financial performance of our assets without regard to financing methods, capital structures, or historical cost basis. Adjusted EBITDA is not intended to represent cash flows from operations or net income (loss) as defined by US GAAP and is not necessarily comparable to similarly titled measures reported by other companies.

We believe Adjusted EBITDA provides relevant and useful information to management, investors, and other users of our financial information in evaluating the effectiveness of our operating performance in a manner that is consistent with management’s evaluation of financial and operating performance.

The table below sets forth the reconciliation of Net income (loss) to Adjusted EBITDA:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2021		2020		2021		2020

Predecessor Discussion

Key Components of Results of Operations

Energy Revenue

A significant majority of Aria's owned projects operate under long-term off-take agreements with investment grade and other creditworthy counterparties that have a weighted average remaining life (based on design capacity) of approximately five years for power projects and approximately ten years for RNG projects as of September 14, 2021. Power that is not covered by long-term off-take agreements is sold either under short-term bilateral agreements or in the wholesale markets. For electricity, these are markets organized and maintained by ISOs and RTOs (e.g., NYISO in New York, ISO-NE in New England and PJM Interconnection, L.L.C. (“PJM”) in the eastern United States). These ISOs and RTOs are well established organizations, regulated by states and FERC. For power sold in the wholesale markets, Aria schedules the output in the day-ahead markets and receives the market price determined by the ISO or RTO through balancing the supply and demand for each day. In most cases Aria implements an optimization of the output sold in wholesale markets by using transmission to move the power into the ISO which offers better prices for RECs.

For RNG, Aria has contracts with long-term off-take agreements with creditworthy counterparties. Some contracts have fixed price off-take arrangements while the remaining sell natural gas and renewable attributes and are subject to market price changes.

63

Aria also generates revenue through the sale of Environmental Attributes. These Environmental Attributes include RECs, RINs and LCFS credits created from the sale of electricity and RNG as a transportation fuel. In most cases, RECs are sold to competitive energy suppliers or utilities. RINs are generally sold to energy companies, and Aria includes revenues from the sale of these renewable attributes in energy related products revenue. REC revenue is recognized at the time power is produced where an active market and a sales agreement exists for the credits. RIN revenue is recognized when the fuel is produced or transferred to a third party where a sales agreement exists.

Construction Revenue

Construction revenue is derived from the installation of RNG plants owned by the nonconsolidated joint ventures. Aria recognizes revenue over time based on costs incurred and a fixed profit mark-up per construction agreement. Any intercompany profit is eliminated.

Cost of Energy

Cost of energy is comprised primarily of labor, parts and outside services required to operate and maintain equipment utilized in generating energy from project facilities and landfill sources. Other costs directly related to the production of electricity and RNG are transportation costs associated with moving gas into pipelines, transmission costs of moving power between the ISOs, electricity consumed in the process of gas production, and royalty payments to landfill owners as stipulated in gas rights agreements.

Cost of Construction

Cost of construction is comprised primarily of labor, equipment and other costs associated with construction contracts revenue incurred to date.

General and Administrative Expenses

General and administrative expenses include offices rentals and costs relating to labor, legal, accounting, treasury, information technology, insurance, communications, human resources, procurement, utilities, property taxes, permitting and other general costs.

Gain (Loss) on Derivative Contracts

Aria used interest rate swaps and caps to manage the risk associated with interest rate cash flows on variable rate borrowings. Changes in the fair values of interest rate swaps and realized losses were recognized as a component of interest expense. The interest rate swaps were measured at fair value by discounting the net future cash flows using the forward LIBOR curve with the valuations adjusted by the counterparties’ credit default hedge rate.

Changes in the fair values of natural gas swap are recognized in gain (loss) on derivative contracts and realized losses are recognized as a component of cost of energy expense. 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.

Net income (loss)	$	(534)	$	532	$	(1,066)	$	84,520	$	(6,071)	$	90,591

Revenues

Revenue decreased by $0.2 million for the three months ended September 14, 2021 as a result of sale of LESPH (part of the Power segment) in June 2021, lower construction revenue and fewer days in the 2021 comparative period, partially offset by higher RIN and power commodity prices. Revenue increased by $14.4 million for the nine months ended September 14, 2021 as result of higher RIN, natural gas, and power commodity pricing, partially offset by lower LESPH revenue as a result of its sale in June 2021 and lower construction revenue.

Cost of Operations

Cost of operations decreased by $7.6 million for the three month period ended September 14, 2021 as a result of sale of LESPH in June 2021, lower construction cost and fewer days in the comparative period partially offset by higher royalty costs. Cost of operations decreased $13.6 million for the nine month period ended September 14, 2021 as result of the sale of LESPH and fewer days compared to the nine month period ended September 30, 2020, partially offset by higher royalty costs.

Equity Investment Income (Loss), Net

Equity investment income increased by $3.9 million for the three month period ended September 14, 2021, and $13.8 million for the nine month period ended September 14, 2021 as a result of Mavrix income being higher, RIN and gas pricing, and the addition of the South Shelby RNG facility.

General and Administrative Expenses

General and administrative expenses increased by $15.4 million for the three month period ended September 14, 2021, and $18.8 million for the nine month period ended September 14, 2021 as a result of merger-related legal, consulting, and personnel costs.

Other Income (Expense), Net

65

Other income (expense), net increased by $3.0 million for the three month period ended September 14, 2021 as a result of less interest expense due to the repayment of debt associated with LESPH in June 2021. Other income (expense), net increased by $66.3 million for the nine month period ended September 14, 2021 as result of the gain on extinguishment of debt associated with the LESPH sale.

Liquidity and Capital Resources (Successor)

Sources and Uses of Funds

Legacy Archaea historically funded its operations and growth with equity and debt financing. The Company's primary uses of cash have been to fund construction of RNG facilities and acquisitions of complementary businesses and landfill gas rights. Following the Business Combinations, and until the Company can generate sufficient cash flow, the Company is expected to primarily finance its project development activities with cash on hand from proceeds from the Business Combinations and available funding under our credit facility as discussed below under "New Credit Facility." The amount and timing of the future funding requirements will depend on many factors, including the pace and results of our acquisitions and project development efforts. We expect that existing cash and cash equivalents, positive cash flows from operations and available borrowings under our credit facility will be sufficient to support our working capital, capital expenditures and other cash requirements for at least the next twelve months and, based on our current expectations, for the foreseeable future thereafter.

Cash

As of September 30, 2021, Archaea had $153.6 million of unrestricted cash and cash equivalents on the balance sheet, and $205.9 million working capital, which together are expected to provide ample liquidity to fund our current operations and near-term development projects. As of September 30, 2021, we also had $17.2 million of restricted cash for payment primarily of construction-related costs for the Assai biogas project.

In November 2021, we issued a redemption notice to the holders of our Public Warrants. We will redeem all of our Public Warrants to purchase shares of our Class A Common Stock, that remain outstanding at 5:00 p.m., New York City time, on December 6, 2021 for a redemption price of $0.10 per Public Warrant. The Public Warrants were issued under the Warrant Agreement, dated October 21, 2020, by and among the Company, LFG Acquisition Holdings LLC and Continental Stock Transfer & Trust Company, as warrant agent, as part of the units sold in the IPO. To minimize dilution to its existing stockholders as a result of warrant exercises, the Company intends to use any cash proceeds received from exercises of its warrants to repurchase shares of Class A Common Stock from Aria Renewable Energy Systems LLC at a price of $17.65 per share. For more information regarding our warrants and the redemption notice, see Note 11—Derivative Instruments to our Consolidated Condensed Financial Statements included herein.

New Credit Facility

On the Closing Date and upon consummation of the Business Combinations, Archaea Energy Operating LLC, a Delaware limited liability company (f/k/a LFG Buyer Co, LLC) (“Archaea Borrower”), entered into a $470 million Revolving Credit and Term Loan Agreement (the “New Credit Agreement”) with a syndicate of lenders co-arranged by Comerica Bank. The New Credit Agreement provides for a senior secured revolving credit facility (the “Revolver”) with an initial commitment of $250 million and a senior secured term loan credit facility (the “Term Loan” and, together with the Revolver, the “Facilities”) with an initial commitment of $220 million. Pursuant to the New Credit Agreement, Archaea Borrower has the ability, subject to certain conditions, to draw upon the Revolver on a revolving basis up to the amount of the Revolver then in effect. On the Closing Date, the Company received total proceeds of $220 million under the Term Loan. As of September 30, 2021, the Company has outstanding borrowings under the Term Loan of $220 million at an effective interest rate of 3.34% and has not drawn on the Revolver. As of September 30, 2021, the Company had issued letters of credit

66

under the New Credit Agreement of $14.7 million, and thus reducing the borrowing capacity of the Revolver to $235.3 million.

Prior to the Archaea Merger, Legacy Archaea had certain other secured promissory notes and credit facilities in place which were extinguished at the Closing of the Business Combinations.

Summarized Cash Flows for the Nine Months Ended September 30, 2021 and 2020

	Nine months Ended September 30,
(in thousands)	2021		2020
Cash used in operating activities	$	(54,710)	$	(2,820)
Cash used in investing activities	$	(587,372)	$	(18,707)
Cash provided by financing activities	$	811,386	$	21,841
Net increase in cash, cash equivalents and restricted cash	$	169,304	$	314

Cash Used in Operating Activities

The Company’s generates cash from revenues and uses cash in its operating activities and for selling, general and administrative expenses.

Total cash used in operating activities increased by $51.9 million for the nine months ended September 30, 2021, which was primarily related to higher general and administrative expenses, increases in employee cost as we continue to build our business, and operating costs associated with the additions of Boyd County and PEI. Changes in other working capital accounts were approximately $40.6 million and related to timing of payable payments and combined company insurance programs.

Cash Used in Investing Activities

We continue to have significant cash outflows for investing activities as we expand our business and develop projects.

Total cash used in investing activities was $587.4 million for the nine months ended September 30, 2021. Excluding the Aria Merger, we spent $86 million on development activities and $31 million related to the PEI acquisition, which primarily consisted of a pipeline that will transport gas to our Assai facility. Development activities in 2021 are related to construction at our various plants, including Assai and the Boyd County facility.

Cash used in investing activities of $18.7 million for the nine months ended September 30, 2020 was primarily comprised of acquiring a majority position in GCES, acquiring biogas rights, and construction at the Assai project.

Cash Provided by Financing Activities

The results of our cash provided by financing activities is primarily attributable to cash proceeds from the Business Combinations, including the PIPE Financing and proceeds from the RAC trust account, and borrowings from long-term debt under the 3.75% Notes, the 4.47% Notes and the New Credit Agreement, offset by certain debt repayments. This resulted in net cash proceeds of $810.9 million.

Cash provided by financing activities of $21.8 million for the nine months ended September 30, 2020 was comprised primarily of equity financing.

Operating Leases

The Company has entered into warehouse and office leases with third parties for periods ranging from one to three years. The Company also entered into a related-party office lease as a result of its acquisition of interest GCES in 2020. During the nine months ended September 30, 2021, the Company paid $0.2 million under this related-party lease which expires in May 2022.

Long Term Debt

Assai Energy 3.75% and 4.47% Senior Secured Notes

On January 15, 2021, Assai Energy, LLC (“Assai”) entered into a senior secured note purchase agreement with certain investors for the purchase of $72.5 million in principal amount of 3.75% Senior Secured Notes (the "3.75% Notes"). Interest on the 3.75% Notes is payable quarterly in arrears on each payment date and mature on September 30, 2031. On April 5, 2021, Assai entered into an additional senior secured note purchase agreement with certain investors for the purchase of $60.8 million in principal amount of its 4.47% Senior Secured Notes (the "4.47% Notes" and, together with the 3.75% Notes, collectively the “Assai Notes”). Interest is payable quarterly in arrears on each payment date, and the 4.47% Notes mature on September 30, 2041. As of September 30, 2021, Assai received total proceeds of $127.4 million from the Assai Notes of which approximately $30 million was used to complete the acquisition of PEI. The remaining proceeds are expected to be used to fund the continued development of Project Assai.

Wilmington Trust, National Association is the collateral agent for the secured parties for the Assai Notes. The Assai Notes are secured by all Assai plant assets and plant revenues and a pledge of the equity interests of Assai. Cash received from the Assai Notes is restricted for use on Assai related costs and cannot be used for general corporate purposes.

New Credit Facilities

On the Closing Date and upon consummation of the Business Combinations, Archaea Energy Operating LLC, a Delaware limited liability company (f/k/a LFG Buyer Co, LLC) (“Archaea Borrower”), entered into a $470 million Revolving Credit and Term Loan Agreement (the “New Credit Agreement”) with a syndicate of lenders co-arranged by Comerica Bank. The New Credit Agreement provides for a senior secured revolving credit facility (the “Revolver”) with an initial commitment of $250 million and a senior secured term loan credit facility (the “Term Loan” and, together with the Revolver, the “Facilities”) with an initial commitment of $220 million. Pursuant to the New Credit Agreement, Archaea Borrower has the ability, subject to certain conditions, to draw upon the Revolver on a revolving basis up to the amount of the Revolver then in effect. On the Closing Date, the Company received total proceeds of $220 million under the Term Loan. As of September 30, 2021, the Company has outstanding borrowings under the Term Loan of $220 million at an effective interest rate of 3.34% and has not drawn on the Revolver. As of September 30, 2021, the Company had issued letters of credit under the New Credit Agreement of $14.7 million, and thus reducing the borrowing capacity of the Revolver to $235.3 million.

Significant Accounting Policies

This management's discussion and analysis of financial condition and results of operations are based on our consolidated financial statements. Our financial statements have been prepared in conformity with GAAP. For a discussion of our significant accounting policies, see Note 2 - Basis of Presentation and Summary of Significant Accounting Policies.

Critical Accounting Policies and Estimates

The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. The estimates and assumptions used in our financial statements are based upon management's evaluation of the relevant facts and circumstances as of the date of the financial statements. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The results form the basis for judgments we make about the carrying values of assets and liabilities that are not readily apparent from other sources. Because these estimates can vary depending on the situation, actual results may differ from the estimates and assumptions used in preparing the financial statements.

We identify the most critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and results of operations and that require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain. Our critical accounting policies are associated with revenue recognition, acquisition accounting, and the judgment used in determining the fair value of identified assets acquired and liabilities assumed.

69

Revenue Recognition

We recognize revenue in accordance with ASC 606, "Revenue from Contracts with Customers" or in accordance with ASC 840, "Leases" depending on the terms of the related sales agreements. 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 Archaea expects to be entitled in exchange for those goods or services. Under ASC 840, lease revenue is recognized generally upon delivery of RNG, electricity and related renewable Environmental Attributes.

Our revenues are comprised of sales of renewable electricity generation (Power), renewable natural gas (RNG), renewable energy attributes, and customized pollution control equipment and maintenance agreement services. 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

Our RNG production started during 2021 as a result of the acquisition of Aria in connection to the Business Combinations and the commencement of operations in April 2021 at the Boyd County facility. We have long-term off-take contracts with creditworthy counterparties. Most long-term off-take contracts are accounted for as operating leases, have no minimum lease payments, and all of the rental income under these leases is recorded as revenue when the RNG is delivered to the customer. RNG not covered by off-take contracts are sold under short-term market based contracts. When the performance obligation is satisfied through the delivery of RNG to the customer, revenue is recognized. We usually receive payments from the sale of RNG production within one month after delivery.

We also earn revenue by selling Environmental Attributes known as renewable identification numbers (RINs), which are generated when producing and selling RNG. The majority of RINs are generated by plants for which we have off-take agreements to sell all of the outputs and are therefore accounted for as operating leases, and revenue is recognized when the fuel is produced and transferred to a third party. The remaining RIN sales were under short-term contracts, and revenue is recognized when the RIN is transferred to a third party. We also generate and sell LCFS credits at some of our RNG projects through offtake contracts similar to RINs. LCFS is state level program administered by California Air Resources Board (CARB). LCFS credits are generated as the RNG is sold as vehicle fuel in California.

There is a general lag in the generation and sale of RIN and LCFS credits subsequent to a facility being placed into operation. While each new facility is eligible to register under the federal Renewable Fuel Standard ("RFS") upon initial production and pipeline injection, Archaea has external parties certify its plants under EPA’s voluntary Quality Assurance Plan (“QAP”) in order to maximize the value of its D3 RINs. The initial QAP review generally requires evaluation of up to 90 days of operational data prior to achieving Q-RIN status. Once registration is obtained from the EPA and Q-RIN status achieved, Archaea can generate RINs. RINs are generated monthly for the previous month of production, after which the RINs may be sold. Quarterly and annual reports are required to maintain RFS registration and Q-RIN status for each facility.

LCFS registration requires a minimum of 90 days operational data for a provisional pathway application. Following the application submission, there is a mandatory third-party validation period ranging from three to six months. During this time, LCFS credits can be generated for the facility using a temporary carbon intensity (CI) score, which is typically higher than the expected certified CI for our facilities. Following successful pathway validation, the facility is eligible to generate LCFS credits using the new provisional CI score. LCFS credits are generated on a quarterly basis for the previous quarter of production. Credits are then available to be sold. Quarterly and annual reports are required to maintain LCFS registration and certified CI for each facility.

Power

The Company's Power production started during 2021 as a result of the acquisition of Aria in connection with the Business Combinations and the acquisition of PEI Power LLC. A significant portion of the electricity generated is sold and delivered under the terms of Power Purchase Agreements ("PPAs") or other contractual arrangements. Revenue is recognized upon the amount of electricity delivered at rates specified under the contracts. Most PPAs are accounted for as operating leases, have no minimum lease payments, and all of the rental income under these leases is recorded as revenue when the

70

electricity is delivered. PPAs that are not accounted for as leases are considered derivatives and the Company has elected the normal purchase normal sale exception for these contracts, for which revenue is recognized when electricity is delivered. Power not covered by PPAs is typically sold under a market-based contract with a regional transmission organization or in the wholesale markets. When the performance obligation is satisfied through the delivery of Power to the customer, revenue is recognized. We receive payments from the sale of Power production within one month after delivery.

The Company also earns revenue through the sale of Environmental Attributes known as renewable energy credits (RECs), which are generated when producing and selling Power. For REC sales that were under contracts independent from REG sales, revenue is recognized when the REC is transferred to a third party. For REC sales that the contract bundled with Power sales, revenue is recognized at the time REG is produced when an active market and a sales agreement exist for the credits.

Equipment and Related Services

Our performance obligations related to the sales of equipment are satisfied over time. We measure the progress of these arrangements using an input method based on costs incurred. Our performance obligations related to the sales of services related to equipment are satisfied over time because the customer simultaneously receives and consumes the benefits provided by our performance as it performs.

Below-Market Contract Amortization

As a result of the Business Combinations, we have below-market contracts from agreements related to the sale of RNG in future periods for which the fair value has been determined to be less than market that are being amortized to revenue over the remaining life of the underlying contract.

Acquisition Accounting

The Company applies ASC 805, Business Combinations, when accounting for acquisitions, with identifiable assets acquired, liabilities assumed and noncontrolling interest, if applicable, recorded at their estimated fair values at the acquisition date. Significant judgment is required in determining the acquisition date fair value of the assets acquired and liabilities assumed, predominantly with respect to property, plant and equipment and intangible assets consisting of biogas contracts, trade names and customer relationships. Evaluations include numerous inputs, including forecasted cash flows that incorporate the specific attributes of each asset including age, useful life, equipment condition and technology, and current replacement costs for similar assets. Other key inputs that require judgment include discount rates, comparable market transactions, estimated useful lives and probability of future transactions. The Company evaluates all available information, as well as all appropriate methodologies, when determining the fair value of assets acquired, liabilities assumed, and noncontrolling interest, if applicable, in a business combination. In addition, once the appropriate fair values are determined, the Company must determine the remaining useful life for property, plant and equipment and the amortization period and method of amortization for each finite-lived intangible asset.

Recent Accounting Pronouncements

For a description of the Company’s recently adopted accounting pronouncements and recently issued accounting standards not yet adopted, see Note 3 - Recently Issued and Adopted Accounting Standards of the consolidated financial statements appearing in this Form 10-Q.

Off-Balance Sheet Arrangements

As of September 30, 2021, the Company did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

Inflation

The Company does not believe that inflation had a material impact on our business, revenues or operating results during the periods presented.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As a smaller reporting company, we are not required to provide the information required by this Item. However, we note that we are exposed to market risks in the ordinary course of our business. Market risk is the potential loss that may result from market changes associated with our power generation or with an existing or forecasted financial or commodity transaction. These risks primarily consist of commodity price risk, specifically electricity and renewable natural gas, counterparty credit risk and interest rate risk.

Commodity Price Risk

Changes in energy commodity prices, such as natural gas and wholesale electricity prices, could significantly affect our revenues and expenses. We seek to contract a majority of our RNG volumes under long-term fixed price off-take agreements. We believe these fixed-price arrangements will reduce our exposure to fluctuating energy and commodity prices, as well as the fluctuating prices of Environmental Attributes. However, if our costs were to rise unexpectedly, the revenue under our fixed-price contracts would remain constant, which may result in operating losses.

Counterparty Credit Risk

Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. We monitor and manage credit risk through credit policies that include: (i) an established credit approval process, and (ii) the use of credit mitigation measures such as prepayment arrangements or volumetric limits. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. We seek to mitigate counterparty risk by having a diversified portfolio of counterparties. One of our major customers is BP, a partner in our Mavrix joint venture, and has historically represented approximately 30% to 50% of legacy Aria revenues.

Interest Rate Risk

We are exposed to fluctuations in interest rates through our issuance of variable rate debt. Exposures to interest rate fluctuations may be mitigated by entering into derivative instruments known as interest rate swaps, caps, collars and put or call options. These contracts reduce exposure to interest rate volatility and may result in primarily fixed rate debt obligations when taking into account the combination of variable rate debt and the interest rate derivative instrument. Our risk management policies allow us to reduce interest rate exposure from variable rate debt obligations.

ITEM 4.     CONTROLS AND PROCEDURES

Management’s Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of September 30, 2021. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes to Internal Controls

As discussed elsewhere in this Quarterly Report on Form 10-Q, the Company completed the Business Combinations on September 15, 2021 pursuant to which the Company completed a reverse recapitalization with RAC and acquired Aria. Prior to the Business Combinations, RAC was a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or other similar Business Combination with one or more target businesses. As a result, previously existing internal controls are no longer applicable or comprehensive enough as of the assessment date as the Company’s operations prior to the Business Combinations were insignificant compared to those of the consolidated entity post-Business Combinations. We are in the process of reviewing, re-designing, and in some cases designing our internal controls over financial reporting for the post-Business Combinations. The design and implementation of internal controls over financial reporting for the Company's post-Business Combinations has required and will continue to require significant time and resources from management and other personnel. The changes to our internal control over financial reporting commenced during the period covered by this report and after will materially affect, or are reasonably likely to materially affect, our internal control over financial

72

reporting by establishing new controls and procedures appropriate to the operating business we have become as a result of the Business Combinations.

73

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

From time to time, the Company is party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, management does not currently expect these matters to have a materially adverse effect on the financial position or results of operations of the Company.

ITEM 1A. RISK FACTORS

As a smaller reporting company, we are not required to disclose any material changes from risk factors as previously disclosed in RAC’s Annual Report on Form 10-K/A for the period ended December 31, 2020. However, for a discussion of risk factors applicable to us, please refer to the Registration Statement on Form S-1 (File No. 333-260094), originally filed by the Company with the SEC on October 6, 2021, as subsequently amended on October 18, 2021 and declared effective by the SEC on October 21, 2021. As a result of the closing of the Business Combinations on September 15, 2021, the risk factors previously discussed in Part I, Item 1A. “Risk Factors” of RAC’s Annual Report Form 10-K/A for the period ended December 31, 2020 no longer apply.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We had no sales of unregistered equity securities during the period covered by this Quarterly Report on Form 10-Q that were not previously reported in a Current Report on Form 8-K.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES
