RISK FACTORS

Any investment in shares of Class A Common Stock involves a high degree of risk. You should carefully consider all of the information contained in this prospectus supplement, the accompanying prospectus and any subsequent prospectus supplement, including our financial statements and related notes, before deciding whether to purchase shares of Class A Common Stock. In particular, you should carefully consider, among other things, the risks and uncertainties related to our company and the ownership of shares of Class A Common Stock beginning on page 7 of the accompanying prospectus as well as the risks and uncertainties discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, which is a part of the accompanying prospectus. However, such risks and those discussed elsewhere in the accompanying prospectus and in any subsequent prospectus supplement are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect us. If any of the risks described in the accompanying prospectus or in any subsequent prospectus supplement or others not specified therein materialize, our business, financial condition and results of operations could be materially and adversely affected. In that case, you may lose all or part of your investment.

USE OF PROCEEDS

Archaea will not receive any proceeds from the sale of shares of Class A Common Stock by the Selling Stockholder, including if the underwriters exercise their option to purchase additional shares of Class A Common Stock from the Selling Stockholder. The Selling Stockholder will receive all of the net proceeds from the sale of these shares. For more information about the Selling Stockholder, see “Selling Stockholder.”

DIVIDEND POLICY

We have never paid any cash dividends on the Class A Common Stock. The payment of cash dividends in the future will be dependent upon revenues and earnings, if any, capital requirements and general financial condition from time to time. The payment of any cash dividends will be within the discretion of our board of directors. It is presently expected that we will retain any future earnings to support operations and to finance the growth and development of our business, and accordingly, it is not expected that our board of directors will declare any cash dividends in the near term.

SELLING STOCKHOLDER

The Selling Stockholder is a holder of shares of Class B Common Stock and Opco Class A units originally acquired pursuant to the Aria Merger Agreement. Pursuant to the Second Amended and Restated Limited Liability Company Agreement of Opco (the “Opco LLC Agreement”), at the request of the holder, each Opco Class A unit may be redeemed for, at Opco’s election, a newly-issued share of Class A Common Stock or a cash payment equal to the Cash Election Amount (as defined therein), and upon redemption of such Opco Class A unit, a share of Class B Common Stock shall be surrendered by the holder and cancelled by the Company. Immediately prior to the consummation of this offering, 12,993,603 Opco Class A units (or 14,942,643 Opco Class A units if the underwriters exercise their option to purchase additional shares in full) held by the Selling Stockholder will be redeemed for an equivalent number of shares of Class A Common Stock, and an equivalent number of shares of Class B Common Stock will be surrendered by the Selling Stockholder and cancelled by the Company.

In connection with the Business Combinations, we entered into a stockholders’ agreement, dated as of September 15, 2021 (the “Stockholders Agreement”), with the Selling Stockholder and certain of our other stockholders who received Opco Class A units and shares of Class B Common Stock pursuant to the Business Combinations, which provides such stockholders with certain registration rights with respect to their shares of Class A Common Stock held by them (or issuable upon the redemption of their Opco Class A units). The Stockholders Agreement also grants the Ares Investor (as defined in the Stockholders Agreement and which generally means the Selling Stockholder and its affiliates) the right to designate one director for appointment or election to our board of directors for so long as the Ares Investor holds at least 50% of the Registrable Securities (as defined in the Stockholders Agreement) held by it on the closing date of the Business Combinations. See “Certain Relationships and Related Transactions — Archaea’s and Archaea Energy’s Related Party Transactions — Stockholders Agreement” in the accompanying prospectus for additional information about the Stockholders Agreement.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax considerations related to the purchase, ownership and disposition of Class A Common Stock by a non-U.S. holder (as defined below), but does not purport to be a complete analysis of all potential tax considerations related thereto. This summary is limited to non-U.S. holders who purchase Class A Common Stock sold pursuant to this offering and who hold shares of Class A Common Stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), (generally, for investment purposes).

This summary is based on the current provisions of the Code, final, temporary and proposed U.S. Treasury regulations promulgated thereunder, administrative rulings and pronouncements and judicial decisions and published positions of the Internal Revenue Service (the “IRS”), all as in effect on the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different than those set forth below. We have not sought and will not seek any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions or that a court would not sustain any challenge by the IRS in the event of litigation.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws or any tax treaties. This summary also does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as:

•        banks, insurance companies or other financial institutions;

•        tax-exempt organizations or governmental organizations;

•        qualified foreign pension funds defined in Section 897(l)(2) of the Code (or any entities all of the interests of which are held by a qualified foreign pension fund);

•        brokers or dealers in securities or currencies;

•        traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

•        persons subject to the alternative minimum tax;

•        partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

•        persons deemed to sell Class A Common Stock under the constructive sale provisions of the Code;

•        “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

•        persons that acquired Class A Common Stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

•        individual citizens or residents of the United States;

•        certain former citizens or long-term residents of the United States;

•        except to the limited extent discussed below, persons who actually or constructively own more than 5% of the Class A Common Stock;

•        persons subject to the anti-inversion rules of Section 7874 of the Code; and

•        persons that hold Class A Common Stock as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction, wash sale or other integrated investment or risk reduction transaction.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT INTENDED AS TAX ADVICE. PROSPECTIVE INVESTORS ARE ENCOURAGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Non-U.S. Holder Defined

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of Class A Common Stock that is not a partnership or other pass-through entity for U.S. federal income tax purposes (or an investor therein) or any of the following:

•        an individual who is a citizen or resident of the United States;

•        a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•        an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•        a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more United States persons (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Class A Common Stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, upon the activities of the partnership and the partner, and upon certain determinations made at the partner level. Accordingly, we urge partnerships and partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of Class A Common Stock to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of Class A Common Stock by such partnership.

Distributions on Class A Common Stock

If we make distributions of cash or other property on the Class A Common Stock, other than certain pro rata distributions of Class A Common Stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, the distributions will be treated as a non-taxable return of capital, which will reduce the non-U.S. holder’s tax basis in the Class A Common Stock until such basis equals zero, and thereafter as capital gain from the sale or exchange of such Class A Common Stock. See “— Gain on Disposition of Class A Common Stock.” Subject to the withholding requirements applicable to the ownership of common stock of a USRPHC (as defined below), under FATCA (as defined below) and with respect to effectively connected dividends, each of which is discussed below, any dividends paid to a non-U.S. holder on the Class A Common Stock generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividend unless an applicable income tax treaty provides for a lower rate. To receive the benefit of a reduced treaty rate, a non-U.S. holder must generally provide the applicable withholding agent with a properly completed and executed IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form certifying qualification for the reduced rate. A non-U.S. holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Dividends paid to a non-U.S. holder that are effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, are treated as attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code). Such effectively connected dividends will not be subject to U.S. federal withholding tax if the non-U.S. holder satisfies certain certification requirements by providing the applicable withholding agent with a properly completed and executed IRS Form W-8ECI (or other applicable or successor form) certifying eligibility for exemption. If the non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax at a 30% rate (or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the manner of claiming the benefits of such treaty.

Gain on Disposition of Class A Common Stock

Subject to the discussion below under “— Backup Withholding and Information Reporting” and “— Additional Withholding Requirements Under FATCA,” a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other taxable disposition of Class A Common Stock unless:

•        the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met;

•        the gain is effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States); or

•        the Class A Common Stock constitutes a United States real property interest by reason of us being or having been a United States real property holding corporation (a “USRPHC”) for U.S. federal income tax purposes.

A non-U.S. holder described in the first bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as specified by an applicable income tax treaty) on the amount of such gain, which generally may be offset by U.S. source capital losses.

A non-U.S. holder whose gain is described in the second bullet point above or, subject to the exceptions described in the next paragraph, the third bullet point above, generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code) unless an applicable income tax treaty provides otherwise. If such non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include any effectively connected gain described in the second bullet point above.

Generally, a corporation is a USRPHC if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. If we are or were to become a USRPHC, as long as the Class A Common Stock is and continues to be regularly traded on an established securities market, only a non-U.S. holder that actually or constructively owns, or owned at any time during the shorter of the five-year period ending on the date of the disposition or the non-U.S. holder’s holding period for the Class A Common Stock, more than 5% of the Class A Common Stock will be taxed on gain realized on the taxable disposition of the Class A Common Stock as a result of our status as a USRPHC. If the Class A Common Stock were not considered to be regularly traded on an established securities market, such non-U.S. holder (regardless of the percentage of stock owned) would be subject to U.S. federal income tax on a taxable disposition of the Class A Common Stock (as described in the preceding paragraph), and a 15% withholding tax would apply to the gross proceeds from such disposition (and to any distributions treated as a non-taxable return of capital or capital gain from the sale or exchange of such Class A Common Stock as described above under “— Distributions”).

Non-U.S. holders are urged to consult their tax advisors with respect to the application of the foregoing rules to their ownership and disposition of Class A Common Stock.

Backup Withholding and Information Reporting

Any dividends paid to a non-U.S. holder must be reported annually to the IRS and to the non-U.S. holder. Copies of these information returns may be made available to the tax authorities in the country in which the non-U.S. holder resides or is established. Payments of dividends to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form.

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of Class A Common Stock effected by or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate, which is currently 24%) unless the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of Class A Common Stock effected outside the United States by a non-U.S. office of a broker. However, unless such broker has documentary evidence in its records that the non-U.S. holder is not a United States person and certain other conditions are met, or the non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of Class A Common Stock effected outside the United States by such a broker if it has certain relationships within the United States.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS.

Non-U.S. holders are urged to consult their own tax advisors regarding the application of these rules to their particular circumstances.

Additional Withholding Requirements Under FATCA

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and administrative guidance issued thereunder (“FATCA”), impose a 30% withholding tax on any dividends paid on the Class A Common Stock and (subject to the proposed U.S. Treasury regulations discussed below) on the gross proceeds from a sale or other disposition of Class A Common Stock, in each case, if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with U.S. owners), (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or provides the applicable withholding agent with a certification identifying the direct and indirect substantial United States owners of the entity (in either case, on a properly completed and executed IRS Form W-8BEN-E or successor form, as applicable), or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as a properly completed and executed IRS Form W-8BEN-E or successor form, as applicable). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these rules may be subject to different rules. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes. Proposed U.S. Treasury regulations that may be relied upon pending adoption of final U.S. Treasury regulations have indefinitely suspended the withholding tax on gross proceeds. Non-U.S. holders are encouraged to consult their tax advisors regarding the effects of FATCA on their investment in the Class A Common Stock.

INVESTORS CONSIDERING THE PURCHASE OF CLASS A COMMON STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS AND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

Under the terms of an underwriting agreement, dated the date of this prospectus supplement, with respect to the shares being offered, each of the underwriters named below has severally agreed to purchase from the Selling Stockholder the respective number of shares of Class A Common Stock shown opposite its name below:

The underwriting agreement provides that the underwriters’ obligation to purchase shares of Class A Common Stock depends on the satisfaction of the certain conditions contained in the underwriting agreement including:

•        the obligation to purchase all of the shares of Class A Common Stock offered hereby (other than those shares of Class A Common Stock covered by their option to purchase additional shares as described below), if any of the shares are purchased;

•        the representations and warranties made by us and the Selling Stockholder to the underwriters are true;

•        there is no material change in our business or the financial markets; and

•        we and the Selling Stockholder deliver customary closing documents to the underwriters.

Commissions and Expenses

The following table summarizes the underwriting discounts and commissions the Selling Stockholder will pay to the underwriters. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares. The underwriting fee is the difference between the price to the public and the amount the underwriters pay to the Selling Stockholder for the shares.

Barclays Capital Inc. and Jefferies LLC have advised us that the underwriters propose to offer the shares of Class A Common Stock directly to the public at the offering price on the cover of this prospectus supplement and to selected dealers, which may include the underwriters, at such offering price less a selling concession not in excess of $0.426 per share. If all the shares are not sold at the initial offering price following the initial offering, the representatives may change the offering price and other selling terms.

We estimate that our share of the total expenses of the offering will be approximately $700,000. We have agreed to pay certain expenses, excluding underwriting discounts and commissions, incurred by the Selling Stockholder in connection with this offering.

Option to Purchase Additional Shares

The Selling Stockholder has granted the underwriters an option exercisable for 30 days after the date of this prospectus supplement to purchase, from time to time, in whole or in part, up to an aggregate of 1,949,040 shares from the Selling Stockholder at the offering price less underwriting discounts and commissions. To the extent that this option is exercised, each underwriter will be obligated, subject to certain conditions, to purchase its pro rata portion of these additional shares based on the underwriter’s percentage underwriting commitment in this offering as indicated in the above table.

Lock-Up Agreements

We have agreed that, for a period of 45 days after the date of this prospectus supplement (the “Lock-Up Period”), without the prior written consent of Barclays Capital Inc. and Jefferies LLC, we will not to, directly or indirectly, (i) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or would be expected to, result in the disposition by any person at any time in the future of) any shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock (other than the shares to be sold hereunder; shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans existing on the date hereof; pursuant to currently outstanding warrants or rights not issued under one of those plans; or upon redemption of Opco units pursuant to its Opco LLC Agreement), (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Class A Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Class A Common Stock or other securities, in cash or otherwise, (iii) file, confidentially submit or cause to be confidentially submitted or filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Class A Common Stock or securities convertible, exercisable or exchangeable into Class A Common Stock or any other securities of the Company (other than any registration statement on Form S-8), or (iv) publicly disclose the intention to do any of the foregoing.

Our directors and executive officers and certain beneficial owners of more than 5% of the outstanding shares of Class A Common Stock, including the Selling Stockholder (the “Lock-Up Parties”), have agreed that, for a period of 45 days after the date of this prospectus supplement, subject to certain limited exceptions as described below, without the prior written consent of Barclays Capital Inc. and Jefferies LLC, they will not (i) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or would be expected to, result in the disposition by any person at any time in the future of) any shares of Class A Common Stock (including, without limitation, shares of Class A Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the SEC and shares of Class A Common Stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Class A Common Stock, except sales of the shares to be sold hereunder, (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Class A Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Class A Common Stock or other securities, in cash or otherwise, (iii) make any demand for the filing of or exercise any right or cause to be confidentially submitted or filed, a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company, except for any registration on Form S-8, or (iv) publicly disclose the intention to do any of the foregoing. These restrictions do not apply to: (a) shares of Class A Common Stock acquired in open market transactions, (b) bona fide gifts, sales or other dispositions of shares of any class of the Company’s capital stock, in each case that are made exclusively between and among a Lock-Up Party or members of their family, or affiliates of the Lock-Up Party, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the Lock-Up Party or affiliates of the Lock-Up Party, or as part of a distribution, transfer or disposition to a Lock-Up Party’s members, partners, shareholders or other equity holders, provided that, among other things, the transferee/donee agrees to be bound by the same lock-up restrictions as the Lock-Up Parties, (c) redemptions of Opco units pursuant to the Opco LLC Agreement, provided that any shares of Class A Common Stock issuable upon such redemption will be subject to the above lock-up restrictions, (d) transfers to the Company to the extent necessary to fund the exercise price of options held by a Lock-Up Party and the payment of taxes due with respect to the exercise, vesting, or lapse of substantial risk of forfeiture or other similar taxable event, of restricted stock, restricted stock units, stock options or other rights to purchase or receive shares of Class A Common Stock pursuant to the Company’s stock option or

Barclays Capital Inc. and Jefferies LLC, in their sole discretion, may release the Class A Common Stock and other securities subject to the lock-up agreements described above in whole or in part at any time. When determining whether or not to release Class A Common Stock and other securities from lock-up agreements, Barclays Capital Inc. and Jefferies LLC will consider, among other factors, the holder’s reasons for requesting the release, the number of shares of Class A Common Stock and other securities for which the release is being requested and market conditions at the time.

Indemnification

We and the Selling Stockholder have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

Barclays Capital Inc. may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the Class A Common Stock, in accordance with Regulation M under the Exchange Act:

•        Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•        A short position involves a sale by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase in the offering, which creates the syndicate short position. This short position may be either a covered short position or a naked short position. In a covered short position, the number of shares involved in the sales made by the underwriters in excess of the number of shares they are obligated to purchase is not greater than the number of shares that they may purchase by exercising their option to purchase additional shares. In a naked short position, the number of shares involved is greater than the number of shares in their option to purchase additional shares. The underwriters may close out any short position by either exercising their option to purchase additional shares and/or purchasing shares in the open market. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through their option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

•        Syndicate covering transactions involve purchases of the Class A Common Stock in the open market after the distribution has been completed in order to cover syndicate short positions.

•        Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the Class A Common Stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

Where information has been sourced from a third-party, the source of such information has been identified.

RISK FACTORS

Investing in our securities involves risks. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks set forth herein. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus, any prospectus supplement or in any document incorporated by reference herein or therein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to Our Business and Industry

Our commercial success depends on our ability to identify, acquire, develop and operate LFG projects, as well as our ability to expand production at our current projects.

Our business strategy includes growth primarily through the procurement of landfill gas rights to develop new LFG projects, the acquisition and expansion of existing LFG projects, or conversion of projects from electricity to RNG production. This strategy depends on our ability to successfully identify and evaluate acquisition opportunities and complete new projects or acquisitions on favorable terms. However, we cannot assure you that we will be able to successfully identify new landfill opportunities, acquire additional gas rights and develop new LFG projects, or consummate the acquisition of existing LFG projects, on favorable terms or at all. In addition, we compete with other companies for these development and acquisition opportunities, which may increase our costs or cause us to refrain from making acquisitions at all. We also expect to achieve growth through the expansion of production at certain of our current projects as the related landfills are expanded or otherwise begin to produce more gas, but we cannot assure you that we will be able to reach or renew the necessary agreements with landfill owners on economically favorable terms or at all. If we are unable to successfully identify and consummate future project opportunities or acquisitions of existing projects, or expand electricity and RNG production at our current projects, it will impede our ability to execute our growth strategy. Further, we may also experience delays and cost overruns in converting existing facilities from electricity to RNG production. During the conversion of projects, there may be a gap in production and relating revenue while the electricity project is offline until it commences operation as an RNG facility, which adversely affects our financial condition and results of operations.

Our ability to acquire, develop and operate projects, as well as expand production at current projects, is subject to many risks, including:

•        regulatory changes that affect the value of RNG from Environmental Attributes, which could have a significant effect on the financial performance of our projects and the number of potential projects with attractive economics;

•        changes in energy commodity prices, such as natural gas and wholesale electricity prices, which could have a significant effect on our revenues and expenses;

•        changes in pipeline gas quality standards or other regulatory changes that may limit our ability to transport RNG on pipelines for delivery to third parties or increase the costs of processing RNG to allow for such deliveries;

•        changes in the broader waste collection industry, including changes affecting the waste collection and biogas potential of the landfill industry, which could limit the LFG resource that we currently target for our projects;

•        substantial construction risks, including the risk of delay, that may arise due to forces outside of our control, including those related to engineering and environmental problems, inclement weather and labor disruptions;

•        operating risks and the effect of disruptions on our business, including the effects of global health crises such as COVID-19, weather conditions, catastrophic events such as fires, explosions, earthquakes, droughts and acts of terrorism, and other force majeure events on us, our customers, suppliers, distributors and subcontractors;

•        accidents involving personal injury or the loss of life;

•        entering into markets where we have less experience, such as our projects for biogas recovery at livestock farms;

•        the ability to obtain financing for a project on acceptable terms or at all and the need for substantially more capital than initially budgeted to complete projects and exposure to liabilities as a result of unforeseen environmental, construction, technological or other complications;

•        failures or delays in obtaining desired or necessary land rights, including ownership, leases, easements, zoning rights and building permits;

•        a decrease in the availability, pricing and timeliness of delivery of raw materials and components, necessary for the projects to function;

•        obtaining and keeping in good standing permits, authorizations and consents from local city, county, state and U.S. federal governments as well as local and U.S. federal governmental organizations;

•        penalties, including potential termination, under short-term and long-term contracts for failing to deliver RNG in accordance with our contractual obligations;

•        unknown regulatory changes related to RNG which may increase the transportation cost for delivering under contracts in place;

•        the consent and authorization of local utilities or other energy development off-takers to ensure successful interconnection to energy grids to enable power and gas sales; and

•        difficulties in identifying, obtaining and permitting suitable sites for new projects.

Any of these factors could prevent us from acquiring, developing, operating or expanding our projects, or otherwise adversely affect our business, financial condition and results of operations.

Acquiring existing projects involves numerous risks.

The acquisition of existing LFG projects and companies involves numerous risks, many of which may be indiscoverable through the due diligence process, including exposure to previously existing liabilities and unanticipated costs associated with the pre-acquisition period; difficulty in integrating the acquired projects into our existing business; and, if the projects are in new markets, the risks of entering markets where we have limited experience, less knowledge of differences in market terms for gas rights agreements and off-take agreements, and, for international projects, possible exposure to geopolitical risk as well as exchange-rate risk to the extent we need to finance development and operations of foreign projects to repatriate earnings generated by such projects. While we perform due diligence on prospective acquisitions, we may not be able to discover all potential operational deficiencies in such projects. A failure to achieve the financial returns we expect when we acquire LFG projects could have a material adverse effect on our ability to implement our growth strategy and, ultimately, our business, financial condition and results of operations.

Risks related to acquiring existing projects include:

•        the purchase price we pay could significantly deplete our cash reserves or result in dilution to our existing stockholders;

•        the acquired companies or assets may not improve our customer offerings or market position as planned;

•        we may have difficulty integrating the operations and personnel of the acquired companies;

•        key personnel and customers of the acquired companies may terminate their relationships with the acquired companies as a result of or following the acquisition;

•        we may experience additional financial and accounting challenges and complexities in areas such as tax planning and financial reporting;

•        we may incur additional costs and expenses related to complying with additional laws, rules or regulations in new jurisdictions;

•        we may assume or be held liable for risks and liabilities (including for environmental-related costs) as a result of our acquisitions, some of which we may not discover during our due diligence or adequately adjust for in our acquisition arrangements;

•        our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically diverse enterprises;

•        we may incur one-time write-offs or restructuring charges in connection with an acquisition;

•        we may acquire goodwill and other intangible assets that are subject to amortization or impairment tests, which could result in future charges to earnings; and

•        we may not be able to realize the cost savings or other financial benefits we anticipated.

In order to secure contracts for new projects, we typically face a long and variable development cycle that requires significant resource commitments and a long lead time before we realize revenues.

The development, design and construction process for our renewable energy projects generally lasts from 24 to 36 months, on average. Prior to signing a development agreement, we typically conduct a preliminary audit of the site host’s needs and assess whether the site is commercially viable based on our expected return on investment, investment payback period, and other operating metrics, as well as the necessary permits to develop a project on that site. This extended development process requires the dedication of significant time and resources from our sales and management personnel, with no certainty of success or recovery of our expenses. A potential site host may go through the entire sales process and not accept our proposal. Further, upon commencement of operations, it typically takes several months for the project to ramp up to our expected production level. All of these factors, and in particular, increased spending that is not offset by increased revenues, can contribute to fluctuations in our quarterly financial performance and increase the likelihood that our operating results in a particular period will fall below investor expectations.

Our business plans include expanding from LFG projects into other types of feedstocks or transmission projects. Any such expansions of non-LFG projects or transmission projects may present unforeseen challenges and result in a competitive disadvantage relative to our more-established competitors.

We currently operate primarily LFG projects that convert landfill gas into renewable electricity and RNG. However, we are actively developing projects that use anaerobic digesters to capture and convert emissions into low-carbon, RNG, electricity and hydrogen, and may expand into additional feedstocks in the future. In addition, we are actively considering expansion into other lines of business, including carbon sequestration, renewable electricity for our projects from solar and the production of low-carbon hydrogen. These projects could expose us to increased operating costs, unforeseen liabilities or risks, and regulatory and environmental concerns associated with entering new sectors of the energy industry, including requiring a disproportionate amount of our management’s attention and resources, which could have an adverse impact on our business as well as place us at a competitive disadvantage relative to more established non-LFG market participants.

Sequestering carbon dioxide is subject to numerous laws and regulations with uncertain permitting timelines and costs. We also intend to explore the production of low-carbon hydrogen sourced from a number of our projects’ RNG, and we may enter into long-term fixed price off-take contracts for low-carbon hydrogen that we may produce at our projects. We are actively evaluating the addition of hydrogen development at two of our RNG development projects in California that could come online as soon as 2023. We do not have an operating history in the low-carbon hydrogen market and our forward projections are based on uncertain operations in the future.

Some projects in which we might invest in the future may be subject to cost-of-service rate regulation, which would limit our potential revenue from such projects. If we invest, directly or indirectly, in an electric transmitting project that allows us to exercise transmission market power, FERC could require our affiliates with MBR power sales authority to implement mitigation measures as a condition of maintaining our or our affiliates’ MBR authority.

FERC regulations limit using a transmission project for proprietary purposes, and we may be required to offer others (including competitors) open-access to our transmission asset, should we acquire one. Such acquisitions could have a material adverse effect on our business, financial condition and results of operations.

Other types of feedstock, specifically livestock waste and dairy farm projects, produce significantly less RNG than landfill facilities. As a result, the commercial viability of these projects is even more dependent on various factors and market forces outside of our control, like changes to law or regulations that could affect the value of our projects or the incentives available to them. In addition to these known factors, there are other factors currently unknown to us that may affect the commercial viability of other types of feedstock. As such, expansion into other types of feedstock could adversely affect our business, financial condition, and results of operations.

Our fixed-price contracts create the potential for operating losses in the event our variable costs rise unexpectedly; conversely, our contracts that are not on a fixed-price basis expose us to the risk of price fluctuations.

We sell, and expect to continue to sell, the majority of our RNG volumes under long-term fixed price off-take agreements. We believe our fixed-price arrangements reduce our exposure to fluctuating energy and commodity prices. However, if our costs were to rise unexpectedly, the revenue under our fixed-price contracts would remain constant, which may result in operating losses.

Conversely, selling our RNG volumes on a merchant pricing basis allows us to capture the value of prevailing LCFS and RIN credits; however, the value of such Environmental Attributes has historically been volatile and remains difficult to forecast. Although we aim to cap our exposure to merchant pricing by contracting a significant portion of our production with long-term fixed priced contracts, we may not be able to increase the amount of our production that is covered by such contracts or even maintain our historical and/or targeted percentages.

The price of RINs and other Environmental Attributes is driven by various market forces that are difficult to predict, including gasoline prices and the availability of renewable fuel from other renewable energy sources and conventional energy sources. We may be unable to manage the risk of volatility in RIN pricing for all or a portion of our revenues from RINs, which would expose us to the volatility of commodity prices with respect to all or the portion of RINs that we are unable to sell through forward contracts, including risks resulting from changes in regulations, general economic conditions and changes in the level of renewable energy generation. We expect to have quarterly variations in the revenues from the projects in which we generate revenue from the sale of RINs that we are unable to sell through forward contracts.

Further, the production of RINs significantly in excess of the RVOs set by the EPA for a calendar year could adversely affect the market price of RINs, particularly towards the end of the year, if refiners and other importers subject to the RFS program have satisfied their RVOs for the year.

A significant decline in the price of Environmental Attributes, such as RINs, for a prolonged period could adversely affect our business, financial condition and results of operations, and could require us to take an impairment charge relating to one or more of our projects.

A prolonged environment of low prices or reduced demand for electricity or RNG could have a material adverse effect on our long-term business prospects, financial condition and results of operations.

Long-term electricity and RNG prices may fluctuate substantially due to factors outside of our control. The price of electricity can vary significantly for many reasons, including increases and decreases in generation capacity in our markets; changes in power transmission or fuel transportation capacity constraints or inefficiencies; power supply disruptions; weather conditions; seasonal fluctuations; changes in the demand for power or in patterns of power usage, including the potential development of demand-side management tools and practices; development of new fuels or new technologies for the production of power; federal and state regulations; and actions of the ISOs and RTOs that control and administer regional power markets.

If we are unable to renew or replace an off-take agreement for a project for which we continue to produce RNG, we would be subject to the risks associated with selling the RNG produced at that project at then-current market prices. We may be required to make such sales at a time when the market price for natural gas as a whole or

in the region where that project is located, is depressed. If this were to occur, we would be subject to the volatility of gas prices and be unable to predict our revenues from such project, and the sales prices for such RNG may be lower than what we could sell the RNG for under an off-take agreement.

Further, the amount of power consumed by the electric utility industry is affected primarily by the overall demand for electricity, environmental and other governmental regulations and the price and availability of fuels such as nuclear, coal, natural gas and oil, as well as sources of renewable energy. A decline in prices for certain fuels or reduced government incentives for renewable energy sources could also make LFG projects less cost-competitive on an overall basis. Slow growth or a long-term reduction in overall demand for energy could have a material adverse effect on our business strategy and could, in turn, have a material adverse effect on our business, financial condition and results of operations.

A reduction in the prices we can obtain for our RECs could have a material adverse effect on our long-term business prospects, financial condition and results of operations.

A significant portion of our power revenues come from the sale of RECs, whether bundled in the price of our production or sold separately. RECs exist because of legal and governmental regulatory requirements, and a change in law or in governmental policies concerning renewable electricity, LFG or the sale of RECs could be expected to affect the market for, and the pricing of, the RECs that we can generate through production at our renewable energy projects. A reduction in the prices we receive for RECs, whether individually or as a portion of the price we receive for our power sales, or a reduction in demand for RECs could have a material adverse effect on our results of operations.

We face competition both on the prices we receive for our electricity and RNG and for rights to manage or develop LFG projects.

We face competition from both conventional and renewable energy companies in connection with the prices that we can obtain for the electricity and RNG that we produce and sell into energy markets at wholesale market prices. The prices that these energy companies can offer are dependent on a variety of factors, including their fuel sources, transmission costs, capacity factor, technological advances and their operations and management. If these companies are able to offer their energy at lower prices, this will reduce the prices we are able to obtain in these markets, which could have a material adverse effect on our results of operations. Our competitors may also offer energy solutions at prices below cost, devote significant sales forces to competing with us or attempt to recruit our key personnel by increasing compensation, any of which could improve their competitive positions. In addition, the technologies that we use may be rendered obsolete or uneconomical by technological advances, more efficient and cost-effective processes or entirely different approaches developed by one or more of our competitors or others. Moreover, if the demand for renewable energy increases, new companies may enter the market, and the influx of added competition will pose an increased risk to us.

In the LFG industry, we believe our primary competitors are other LFG companies with existing projects and landfill owners that either operate their own LFG projects or may do so in the future. We compete with these companies to acquire landfill gas rights for development or existing LFG projects with projected stable cash flows, or in some cases to renew or extend existing gas rights or off-take agreements. Increased competition for such projects may increase the price we pay for gas rights, the acquisition costs for existing projects or the royalties we have to pay landfill owners, which may have a material adverse effect on our results of operations. We may also find ourselves competing more frequently with landfill owners to the extent they decide to develop their own LFG projects, which would also reduce the number of opportunities for us to develop new LFG projects.

Our renewable energy projects may not produce expected levels of output, and the amount of LFG actually produced at each of our projects will vary over time and, when a landfill closes, eventually decline.

Landfills contain organic material whose decomposition causes the generation of gas consisting primarily of methane, which LFG projects use to generate power or RNG, and carbon dioxide. See “Business — Business Overview.” The estimation of LFG production volume is an inexact process and dependent on many site-specific conditions, including the estimated annual waste volume, composition of waste, regional climate and the capacity and construction of the landfill. Production levels are subject to a number of additional risks, including a failure or wearing out of our or our landfill operators’, customers’ or utilities’ equipment; an inability to find suitable

replacement equipment or parts; less than expected supply or quality of the project’s source of biogas and faster than expected diminishment of such biogas supply; or volume disruption in our fuel supply collection system. As a result, the amount of LFG actually produced by the landfill sites from which our projects collect LFG or the volume of electricity or RNG generated from those sites may in the future vary from our initial estimates, and those variations may be material. In addition, we have in the past, and may in the future, incur material asset impairment charges if any of our renewable energy projects incurs operational issues that indicate our expected future cash flows from the project are less than the project’s carrying value. Any such impairment charge could adversely affect our operating results in the period in which the charge is recorded.

Generally the amount of gas produced at a landfill increases for up to three years after it stops collecting waste, at which time the gas volume begins to gradually decline. As of June 30, 2021, one of the landfills where our projects are located is a closed landfill. Of the remaining 32 landfills, one is currently expected to close within the next three years and another five are currently expected to close within the next ten years, based upon current permits which are eligible to receive extensions to accept waste for additional time periods. If we do not develop or acquire projects attached to open or expanding landfills, over time the total amount of LFG available to operate our projects would decline, which could have a material adverse effect on our business, financial condition and results of operations.

In addition, in order to maximize collection of LFG, various measures need to be taken, such as drilling additional gas wells in the landfill to increase LFG collection, balancing the pressure on the gas field based on the data collected by the landfill operator from the gas wells to ensure optimum LFG utilization and ensuring that we match availability of engines and related equipment to availability of LFG. There can be no guarantee that we will be able to take all necessary measures to maximize collection. In addition, the LFG available to our projects is dependent in part on the actions of other persons, such as landfill operators. We may not be able to ensure the responsible management of the landfill site by owners and operators, which may result in less than optimal gas generation or increase the likelihood of “hot spots” occurring. Hot spots can temporarily reduce the volume of gas which may be collected from a landfill site, resulting in a lower gas yield. Other events that can result in a reduction in LFG output include: extreme hot or cold temperatures or excessive rainfall; liquid levels within a landfill increasing; oxidation within a landfill, which can kill the anaerobic microbes that produce LFG; and the buildup of sludge. The occurrence of these or any other changes within any of the landfills where our projects operate could lead to a reduction in the amount of LFG being available to operate our projects, which could have a material adverse effect on our business, financial condition and results of operations.

Increased rates of recycling and legislation encouraging recycling, increased use of waste incineration, advances in waste disposal technology and decreases in the gross domestic product of the United States could decrease the availability or change the composition of waste for LFG.

The volume and composition of LFG produced at open landfill sites depends in part on the volume and composition of waste sent to such landfill sites, which could be affected by a number of factors. For example, increased rates of recycling or increased use of waste incineration could decrease the volume of waste sent to landfills, while organics diversion strategies such as composting can reduce the amount of organic waste from landfills. There have been numerous federal and state regulations and initiatives over the years that have led to higher levels of recycling of paper, glass, plastics, metal and other recyclables, and there are growing discussions at various levels of government about developing new strategies to minimize the negative environmental impacts of landfills and related emissions, including diversion of biodegradable waste from landfills. Although many recyclable materials other than paper do not decompose and therefore do not ultimately contribute to the amount of LFG produced at a landfill site, it is too early to conclude definitively what impact recycling and other similar efforts will have on the volume and proportion of biodegradable waste sent to landfill sites across the United States.

In addition, research and development activities are ongoing to provide alternative and more efficient technologies to dispose of waste, to produce by-products from waste and to produce energy, and an increasing amount of capital is being invested to find new approaches to waste disposal, waste treatment and energy generation.

It is possible that this deployment of capital may lead to advances which will adversely affect our sources of LFG or provide new or alternative methods of waste disposal or energy generation that become more accepted, or more attractive, than landfills.

Increased rates of recycling, legislation encouraging recycling, increased use of waste incineration, advancements in waste disposal technology, organics diversion, or an economic downturn in the United States, for any reason, could impact the volume and composition of waste produced in the United States and, as a consequence, the volume and composition of waste sent to landfill sites from which our projects collect LFG, which could adversely affect our business operations, prospects, financial condition and operational results.

We are dependent on contractual arrangements with, and the cooperation of, landfill site owners and operators for access to and operations on their sites.

We do not own any of the landfill sites from which our projects collect LFG or on which we operate and manage projects owned by landfill owners, and therefore we depend on contractual relationships with, and the cooperation of, the landfill site owners and operators for our operations. The invalidity of, or any default or termination under, any of our leases and licenses may interfere with our ability to use and operate all or a portion of certain of our project facilities, which may have an adverse impact on our business, financial condition and results of operations. We obtain gas rights to the landfills on which our projects operate, with some of these gas rights being evergreen and others having fixed terms. Excluding our O&M projects owned by third parties, the gas rights associated with our 23 projects that are not evergreen are due to expire at varying points over the next 24 years, with gas rights to six landfills due to expire by the end of 2031. See “Business — Market Opportunity.” While we have historically been successful in renewing gas rights as they expire on favorable terms, we have sometimes had to pay increased royalty payments in connection with renewals of gas rights to reflect then-current market terms. We cannot guarantee that we will be able to renew any gas rights that expire in the future on commercial terms that are attractive to us or at all, and any failure to do so, or any other disruption in the relationship with any of the landfill operators from whose landfill sites our projects obtain LFG or for whom we operate LFG facilities, may have a material adverse effect on our business operations, prospects, financial condition and operational results.

In addition, the ownership interests in the land subject to these easements, leases and rights-of-way may be subject to mortgages securing loans or other liens (such as tax liens) and other easement, lease rights and rights-of-way of third parties (such as leases of oil or mineral rights) that were created prior to our projects’ easements, leases and rights-of-way. As a result, certain of our projects’ rights under these easements, leases or rights-of-way may be subject, and subordinate, to the rights of those third parties. We may not be able to protect our operating projects against all risks of loss of our rights to use the land on which our projects are located, and any such loss or curtailment of our rights to use the land on which our projects are located and any increase in rent due on such lands could adversely affect our business, financial condition and results of operations.

Our gas rights and off-take agreements are subject to certain conditions. A failure to satisfy those conditions could result in the loss of gas rights or the termination of an off-take agreement.

Our gas rights agreements generally require that we achieve commercial operations for a project as of a specified date. If we do not satisfy such a deadline, the agreement may be terminated at the option of the landfill without any reimbursement of any portion of the purchase price paid for the gas rights or any other amounts we have invested in the project. Delays in construction or delivery of engines and other equipment may result in our failing to meet the commercial operations deadline in a gas rights agreement. The denial or loss of a permit essential to a project could impair our ability to construct or operate a project as required under the related gas rights agreement. Delays in the review and permitting process for a project can also impair or delay our ability to construct or acquire a project and satisfy any commercial operations deadlines, or increase the cost such that the project is no longer attractive to us. Likewise, certain of our off-take agreements have required us to achieve commercial operations as of a specified date, and off-take agreements we enter into in the future may have similar requirements. Failure to achieve such deadlines could result in the loss of such an off-take agreement.

Furthermore, certain of our gas rights agreements require us to deliver a minimum quantity of energy to our customers. Any issues with our production at the corresponding projects, including due to weather, unplanned outages or transmission problems, to the extent not caused by the landfill or covered by force majeure provisions in the gas rights agreement, could result in the loss of these gas rights. Our gas rights agreements often grant us the right to build additional generation capacity in the event of increased LFG supply, but failure to use such increased supply after a prescribed period of time can result in the loss of the rights to the unused LFG.

Our gas rights agreements provide that our projects must be operated in compliance with laws and regulations. If our facility causes the landfill to be out of compliance with their permits, we will be obligated to correct the issue or our rights to the LFG can be terminated. Finally, we may acquire gas rights but later determine that developing or continuing to operate a project is not economically desirable, and we may cease development or operations and thereby lose control of such gas rights. Any loss of gas rights associated with any potential future or existing project could impede our ability to execute our growth strategy and have a material adverse effect on our business, financial condition and results of operations.

Finally, certain of the gas rights agreements and off-take agreements for projects in our portfolio and that we may acquire in the future allow or may allow the landfill owner or off-take counterparty to acquire or otherwise purchase a portion or all of the applicable project facilities from us. Any such sale of a project facility could have an adverse effect on our results of operations if we are unable to locate and acquire suitable replacement projects in a timely fashion.

Our projects face operational challenges customary to the energy industry. An unexpected reduction in energy production at any of our projects may have a material adverse effect on our results of operations and could adversely affect the associated off-take agreement.

The ongoing operation of our facilities involves risks that include the breakdown or failure of equipment or processes or performance below expected levels of output or efficiency due to normal wear and tear of our equipment, latent defects, design or operator errors or force majeure events, among other factors. Operation of our facilities also involves risks that we will be unable to transport our product to our customers in an efficient manner due to a lack of transmission capacity or other problems with third party interconnection and transmission facilities. Unplanned outages of equipment, including extensions of scheduled outages due to mechanical failures or other problems, occur from time to time and are an inherent risk of our business. Unplanned outages typically increase our operation and maintenance expenses and may reduce our revenue or require us to incur significant costs as a result of obtaining replacement energy from third parties in the open market to satisfy our energy sales obligations. Landfill owners and operators can also impact our energy generation if in the course of ongoing operations they damage the landfill’s gas collection systems. Our inability to operate our facilities efficiently, manage capital expenditures and costs and generate earnings and cash flow could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are generally also required under our off-take agreements to deliver a minimum quantity of the applicable energy products to the counterparty. Unless we can rely on a force majeure provision in the related off-take agreement, falling below such a threshold could require us to compensate our counterparty for the energy, REC or RIN deficiency for our counterparty in the open market or could result in a reduced rate to be paid for the energy we deliver in the future until any subsequent price reset date in the agreement or permanently, as well as possibly allowing the counterparty to terminate the agreement and subject us to certain termination payments. A reduction in energy production or the loss of an off-take agreement may also result in a project having its permit revoked, which in turn could result in the loss of the related gas rights. Likewise, the denial or loss of a permit essential to a project could impede our ability to satisfy any energy production requirements which we may be subject to under an off-take agreement. Thus, any unexpected reduction in output at any of our projects that leads to any of these outcomes could have a material adverse effect on our business, financial condition and results of operations.

Additionally, certain of our projects have granted subordinated second-lien security interests on certain project assets in order to secure our performance under their GSAs. In the event we are unable to perform under or are otherwise in breach of these agreements, it is possible that the counterparties thereunder could enforce their security interests, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our substantial indebtedness could adversely affect our ability to raise additional capital to fund our operations and acquisitions. It could also expose us to the risk of increased interest rates and limit our ability to react to changes in the economy or our industry.

After giving effect to the Business Combinations and certain other related transactions, our pro forma consolidated indebtedness as of June 30, 2021 would have been approximately $337.1 million, or approximately 25% of our total pro forma capitalization of approximately $1,354.5 million at such date. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” for a discussion of the related pro forma adjustments and assumptions.

Our substantial indebtedness could have important consequences, including, for example:

•        being required to accept then-prevailing market terms in connection with any required refinancing of such indebtedness, which may be less favorable than existing terms;

•        failure to refinance, or to comply with the covenants in the agreements governing, these obligations could result in an event of default under those agreements, which could be difficult to cure or result in our bankruptcy;

•        our debt service obligations require us to dedicate a substantial portion of our cash flow to pay principal and interest on our debt, thereby reducing the funds available to us and our ability to borrow to operate and grow our business;

•        our limited financial flexibility could reduce our ability to plan for and react to unexpected opportunities; and

•        our substantial debt service obligations make us vulnerable to adverse changes in general economic, credit and capital markets, industry and competitive conditions and adverse changes in government regulation and place us at a disadvantage compared with competitors with less debt.

Any of these consequences could have a material adverse effect on our business, financial condition and results of operations. If we do not comply with our obligations under our debt instruments, we may be required to refinance all or part of our existing debt, borrow additional amounts or sell securities, which we may not be able to do on favorable terms or at all. In addition, increases in interest rates and changes in debt covenants may reduce the amounts that we can borrow, reduce our cash flows and increase the equity investment we may be required to make to complete construction of our LFG projects. These increases could cause some of our projects to become economically unattractive. If we are unable to raise additional capital or generate sufficient operating cash flow to repay our indebtedness, we could be in default under our lending agreements and could be required to delay construction of new projects, reduce overhead costs, reduce the scope of our projects or abandon or sell some or all of our projects, all of which could have a material adverse effect on our business, financial condition and results of operations.

In connection with the consummation of the Business Combinations, we 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 “Credit Facilities”) with an initial commitment of $220 million. The Credit Facilities and any future indebtedness contains financial and other restrictive covenants that limits our ability to return capital to stockholders or otherwise engage in activities that may be in our long-term best interests. Our inability to comply with those covenants could result in an event of default which, if not cured or waived, may entitle the related lenders to demand repayment or enforce their security interests, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, failure to comply with such covenants may entitle the related lenders to demand repayment and accelerate all such indebtedness.

In connection with certain project development opportunities, we have utilized project-level financing in the past and may need to do so again in the future; however, we may be unable to obtain such financing on commercially reasonable terms or at all. The agreements governing such financings typically contain financial and other restrictive covenants that limit a project subsidiary’s ability to make distributions to its parent or otherwise engage in activities that may be in its long-term best interests. Project-level financing agreements generally prohibit distributions from

the project entities to us unless certain specific conditions are met, including the satisfaction of certain financial ratios or a facility achieving commercial operations. Our inability to comply with such covenants may prevent cash distributions by the particular project(s) to us and could result in an event of default which, if not cured or waived, may entitle the related lenders to demand repayment or enforce their security interests, which could result in a loss of project assets and/or otherwise have a material adverse effect on our business, results of operations and financial condition.

Existing regulations and policies, and future changes to these regulations and policies, may present technical, regulatory and economic barriers to the generation, purchase and use of renewable energy, and may adversely affect the market for credits associated with the production of renewable energy. See note below about regulatory programs and descriptions of RIN and LCFS programs, located at “Business — Market Opportunity.”

The market for electric energy produced by renewable resources is influenced by U.S. federal, state and local government regulations and policies concerning such resources. These regulations and policies are continuously being modified, which could result in a significant future reduction in the potential demand for renewable energy, including RINs, RECs and LCFS credits, renewable energy project development and investments. Any new government regulations applicable to our renewable energy projects or markets for renewable energy may result in significant additional expenses or related development costs and, as a result, could cause a significant reduction in demand for our renewable energy. Failure to comply with such requirements could result in the disconnection and/or shutdown of the non-complying facility, our inability to sell electricity or RNG from the non-complying facility, the default of any contracts that we have for the sales that were to be made from the non-complying facility, the imposition of liens, fines, refunds and interest, and/or civil or criminal liability.

The EPA annually sets proposed RVOs for D3 RINs in accordance with the mandates established by the Energy Independence and Security Act of 2007 (“EISA”). The EPA’s issuance of timely and sufficient annual RVOs to accommodate the RNG industry’s growing production levels is necessary to stabilize the RIN market. There can be no assurance that the EPA will timely set annual RVOs or that the RVOs will continue to increase or satisfy the growing receivable natural gas market. EPA may set RVOs inaccurately or inconsistently under current law, and the manner in which EPA sets RVOs may change under legislative or regulatory revisions. The current authorization for EPA’s issuance of RVOs will expire beginning in 2023, and to EPA may issue RVOs under a modified system that has yet to be developed, which creates additional uncertainty as to RIN pricing. Uncertainty as to how the RFS program will continue to be administered and supported by the EPA under the new U.S. presidential administration has created price volatility in the RIN market. We cannot assure you that we will be able to monetize the RINs we generate at the same price levels as we have in the past, that production shortfalls will not impact our ability to monetize RINs at favorable current pricing, and that the rising price environment will continue.

On the state level, the economics of RNG are enhanced by low-carbon fuel initiatives, particularly well-established programs in California and Oregon (with several other states also actively considering LCFS initiatives similar to those in California and Oregon). In California’s case, in 2009, CARB adopted LCFS regulations aimed at reducing CI of transportation fuel sold and purchased in the state. A CI score is calculated as grams of CO2 equivalent per megajoule of energy by the fuel; the CI score is dependent upon a full lifecycle analysis that evaluates the GHG emissions associated with producing, transporting, and consuming the fuel. LCFS credits can be generated in three ways: (i) fuel pathway crediting that provides low-carbon fuels used in California transportation; (ii) project-based crediting that reduces GHG emissions in the petroleum supply chain; and (iii) zero emission vehicle crediting that supports the buildout of infrastructure. CARB awards these credits to RNG projects based on each project’s CI score relative to the targeted CI score for both gasoline and diesel fuels. The number of monetizable LCFS credits per unit of fuel increases with a lower CI score. We cannot assure you that we will be able to maintain or reduce our CI score to monetize LCFS credits at favorable current pricing. Moreover, the inability to sell LCFS credits could adversely affect our business. All of our current electric generating facilities are QFs. We are permitted by FERC to make wholesale sales (that is, sales for resale) of electricity from a QF with a net generating capacity that does not exceed 20 megawatts without obtaining MBR authority or any other approval from FERC. A QF typically may not use any fuel other than a FERC-approved alternative fuel, but for limited use of commercial-grade fuel for certain specified start-up, emergency and reliability purposes. We are required to document the QF status of each of our facilities in applications or self-certifications filed with FERC, which typically requires disclosure of upstream facility ownership, fuel and size characteristics, power sales, interconnection matters, and related technical disclosures.

Eligibility for MBR authority is predicated on a variety of factors, primarily including the overall market power that the power seller — together with all of its FERC-defined “affiliates” — has in the relevant market. FERC defines affiliates as entities with a common parent that owns, directly or indirectly, 10 percent or more of the voting securities in the two entities. Accordingly, our eligibility and the eligibility of our affiliates to obtain and maintain MBR authority requires an evaluation of the energy assets owned directly or indirectly by us and each of our affiliates satisfying market-power limitations established by FERC. Certain QFs that we own, and one of our other subsidiaries, hold MBR authority. We may not be able to sell any interest in any of these businesses or facilities absent a prior FERC application and approval process. This may make it more difficult and time-consuming for us to liquidate some of our interests, which could affect our ability to raise cash from our current project portfolio.

The FERC’s orders that grant such wholesale sellers MBR authority reserve the right to revoke or revise that authority if the FERC subsequently determines that the seller can exercise market power in transmission or generation, create barriers to entry, or engage in abusive affiliate transactions. In addition, public utilities are subject to FERC reporting requirements that impose administrative burdens and that, if violated, can expose the company to criminal and civil penalties or other risks.

Our market-based sales are subject to certain market behavior rules established by FERC, and if any of our generating companies are deemed to have violated those rules, we will be subject to potential disgorgement of profits associated with the violation, penalties, refunds of unlawfully collected amounts with interest, suspension or revocation of MBR authority. If such generating companies were to lose their MBR authority, they would be required to obtain the FERC’s acceptance of a cost-of-service rate schedule and could become subject to the significant accounting, record-keeping, and reporting requirements that are typically imposed on vertically-integrated utilities with cost-based rate schedules. This could have a material adverse effect on the rates we are able to charge for power from our facilities.

The regulatory environment for electric generation has undergone significant changes in the last several years due to state and federal policies affecting wholesale competition and the creation of incentives for the addition of large amounts of new renewable generation and, in some cases, transmission assets. These changes are ongoing and we cannot predict the future design of the wholesale power markets or the ultimate effect that the changing regulatory environment will have on our business. Our ability to generate revenue from sales of RINs and LCFS credits depends on our strict compliance with these federal and state programs, which are complex and can involve a significant degree of judgment. If the agencies that administer and enforce these programs disagree with our judgments, otherwise determine that we are not in compliance, conduct reviews of our activities or make changes to the programs, then our ability to generate or sell these credits could be temporarily restricted pending completion of reviews or as a penalty, permanently limited or lost entirely, and we could also be subject to fines or other sanctions. Moreover, the inability to sell RINs and LCFS credits could adversely affect our business.

ISOs and RTOs determine market design, market rules, tariffs, cost allocations and bidding rules for the regional power markets that they operate, and our projects that sell electricity into such markets are subject to these frequently changing regulatory regimes that vary across jurisdictions.

The wholesale sales of electricity that are made by our QFs and other affiliates with MBR authority are subject to FERC regulation. Retail power sales (i.e., sales of electricity to direct end-users) are subject to state utility laws and state utility commission regulations that differ greatly from state to state.

With the exception of the ERCOT, each of the ISOs and RTOs (in New England, New York, the Mid-Atlantic region, the Midwest, the Southwest and California) operate wholesale power markets pursuant to rules set forth in tariffs that must be filed with and accepted by FERC. We currently do not own any QFs within the ERCOT region of Texas. The tariffs adopted by these ISOs and RTOs establish wholesale market rules, including with respect to market clearing practices, pricing rules, end eligibility requirements for market participation. We have no ability to control the price-setting, market-design and other activities and requirements of the ISOs and RTOs except through participation in stakeholder proceedings within such ISOs and RTOs and in proceedings before FERC relating to revisions of tariffs filed with, or rules established by FERC. The types of price limitations and other regulatory mechanisms that the ISOs and RTOs impose may have a material adverse effect on the profitability of our current owned power projects or any power projects we may acquire in the future that sell electricity into such markets. FERC regulations affecting wholesale power sales, and ISO and RTO rules, tariffs and practices are generally beyond our control, and can change frequently. If we enter a new jurisdiction, we will be subject to additional

regulatory requirements with which we may not yet have direct experience. The lack of uniformity of regulatory and business practices, the possibility that requirements and practices will change, and the difficulties we may face in entering new markets with which we are unfamiliar could affect our financial performance in existing and new markets, which could affect our business and results of operations.

The financial performance of our business depends upon tax and other governmental incentives for renewable energy generation, any of which could change at any time and such changes may negatively impact our growth strategy.

Our financial performance and growth strategy depend in part on government policies that support renewable generation and enhance the economic viability of owning renewable electric generation or RNG assets. Renewable generation assets currently benefit from various federal, state and local governmental incentives such as investment tax credits, cash grants in lieu of investment tax credits, loan guarantees, RPS programs, modified accelerated cost-recovery system of depreciation and bonus depreciation. RNG specifically generates meaningful revenue through existing Environmental Attributes provided for under several different programs, most commonly, RFS, LCFS, and RPS. See note below about regulatory programs and descriptions of RIN and LCFS programs, located at “Business — Market Opportunity.”

Many states have adopted RPS programs mandating that a specified percentage of electricity sales come from eligible sources of renewable energy. However, the regulations that govern the RPS programs, including pricing incentives for renewable energy, or reasonableness guidelines for pricing that increase valuation compared to conventional power (such as a projected value for carbon reduction or consideration of avoided integration costs), may change. If the RPS requirements are reduced or eliminated, it could lead to fewer future power contracts or lead to lower prices for the sale of power in future power contracts, which could have a material adverse effect on our future growth prospects. Such material adverse effects may result from decreased revenues, reduced economic returns on certain project company investments, increased financing costs, and/or difficulty obtaining financing.

If we are unable to utilize various federal, state and local government incentives to acquire additional renewable assets in the future, or the terms of such incentives are revised in a manner that is less favorable to us, we may suffer a material adverse effect on our business, financial condition, results of operations and cash flows.

We rely on interconnection and transmission facilities that we do not own or control and that are subject to transmission constraints within a number of our regions. If these facilities fail to provide us with adequate transmission capacity or have unplanned disruptions, we may be restricted in our ability to deliver electric power and RNG to our customers and we may either incur additional costs or forego revenues.

We depend on electric interconnection and transmission facilities and gas pipelines owned and operated by others to deliver the energy we generate at our projects to our customers. Some of our electric generating projects may need to hold electric transmission rights in order to sell power to purchasers that do not have their own direct access to our generators. Our access to electric interconnection and transmission rights is subject to tariffs developed by transmission owners, ISOs and RTOs, which have been filed with and accepted by FERC. These tariffs establish the price for transmission service, and the terms under which transmission service is rendered. Under FERC’s open access transmission rules, tariffs developed and implemented by transmission owners, ISOs and RTOs must establish terms and conditions for obtaining interconnection and transmission services that are not unduly discriminatory or preferential. However, as a generator and seller of power, we do not have any automatic right, in any geographic market, to firm, long-term, grid-wide transmission service without first requesting such service, funding the construction of any upgrades necessary to provide such service, and paying a transmission service rate. Physical constraints on the transmission system could limit the ability of our electric generating projects to dispatch their power output and receive revenue from power sales.

A failure or delay in the operation or development of these distribution channels or a significant increase in the costs charged by their owners and operators could result in the loss of revenues. Such failures or delays could limit the amount of energy our operating facilities deliver or delay the completion of our construction projects, which may also result in adverse consequences under our gas rights agreements and off-take agreements. Additionally, such failures, delays or increased costs could have a material adverse effect on our business, financial condition and results of operations. If a region’s energy transmission infrastructure is inadequate, our recovery of wholesale costs and profits may be limited. In addition, except for transmission projects that have been identified by ISOs and

RTOs in publicly-available studies, or in response to requests for interconnection or transmission service, we cannot predict whether or when transmission facilities will be expanded in specific markets to accommodate requests for interconnection or transmission service within those markets. As a general rule, the transmitting utilities to which our electric generating projects are interconnected are entitled to recover from us all of the direct and indirect costs that our electric facilities may create. As a result, we are responsible for building and funding interconnection and related transmission network upgrade facilities to accommodate requests for interconnection and transmission services. Our development and acquisition of new electric generating projects is affected by these costs.

Operation of LFG facilities involves significant risks and hazards customary to the energy industry. We may not have adequate insurance to cover these risks and hazards, or other risks that are beyond our control.

Energy generation involves hazardous activities, including acquiring and transporting fuel, operating large pieces of rotating equipment and delivering our electricity and RNG to interconnection and transmission systems, including gas pipelines that we own and operate in connection with our medium Btu gas projects. Hazards such as fire, explosion, structural collapse and machinery failure are inherent risks in our operations. These and other hazards can cause significant personal injury or loss of life, severe damage to and destruction of property, plant and equipment and contamination of, or damage to, the environment. The occurrence of any one of these events may result in curtailment of our operations or liability to third parties for damages, environmental cleanup costs, personal injury, property damage and fines and/or penalties, any of which could be substantial. For example, a recent engine fire at our Chautauqua project resulted in damage to the facility that resulted in damage to engines that required repair.

Our facilities or those that we otherwise acquire, construct or operate may be targets of terrorist activities, as well as events occurring in response to or in connection with them, that could result in full or partial disruption of the facilities’ ability to generate, transmit, transport or distribute electricity or RNG. Strategic targets, such as energy-related facilities, may be at greater risk of future terrorist activities than other domestic targets. Hostile cyber intrusions, including those targeting information systems as well as electronic control systems used at the generating plants and for the related distribution systems, could severely disrupt business operations and result in loss of service to customers, as well as create significant expense to repair security breaches or system damage.

Furthermore, certain of our facilities are located in areas prone to tornados in Oklahoma, Tennessee, Indiana and Kansas, and certain of our other projects and suppliers conduct their operations in other locations that are susceptible to natural disasters. The frequency of weather-related natural disasters may be increasing due to the effects of greenhouse gas emissions or related climate change effects. The occurrence of a natural disaster, such as tornados, earthquakes, droughts, floods, wildfires or localized extended outages of critical utilities or transportation systems, or any critical resource shortages, affecting us could cause a significant interruption in our business or damage or destroy our facilities.

We rely on warranties from vendors and obligate contractors to meet certain performance levels, but the proceeds of such warranties or performance guarantees may not cover our lost revenues, increased expenses or liquidated damages payments should we experience equipment breakdown or non-performance by contractors or vendors. We also maintain an amount of insurance protection that we consider adequate to protect against these and other risks but we cannot provide any assurance that our insurance will be sufficient or effective under all circumstances and against all hazards or liabilities to which we may be subject. Also, our insurance coverage is subject to deductibles, caps, exclusions and other limitations. A loss for which we are not fully insured could have a material adverse effect on our business, financial condition, results of operations or cash flows. Because of rising insurance costs and changes in the insurance markets, we cannot provide any assurance that our insurance coverage will continue to be available at all or at rates or on terms similar to those presently available. Our insurance policies are subject to annual review by our insurers and may not be renewed on similar or favorable terms or at all. Any losses not covered by insurance could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our operations are subject to numerous stringent environmental, health and safety laws and regulations that may expose us to significant costs and liabilities.

Our operations are subject to stringent and complex federal, state and local EHS laws and regulations, including those relating to the release, emission or discharge of materials into the air, water and ground, the generation, storage, handling, use, transportation and disposal of hazardous materials and wastes, the health and safety of our employees and other persons, and the generation of RINs and LCFS credits.

These laws and regulations impose numerous obligations applicable to our operations, including the acquisition of permits before construction and operation of our projects; the restriction of types, quantities and concentration of materials that can be released into the environment; the limitation or prohibition of our activities on certain lands lying within wilderness, wetlands and other protected areas; the application of specific health and safety criteria addressing worker protection; and the imposition of substantial liabilities for pollution resulting from the operation of our projects and the ownership of the applicable sites. In addition, construction and operating permits issued pursuant to environmental laws are necessary to operate our business. Such permits are obtained through applications that require considerable technical documentation and analysis, and sometimes require long time periods. Delays in obtaining or renewing such permits, or denial of such permits and renewals, are possible, and would have a negative effect on our financial performance and prospects for growth. These laws, regulations and permits can require expensive pollution control equipment or operational changes to limit actual or potential impacts to the environment.

Numerous governmental entities have the power to enforce difficult and costly compliance measures or corrective actions pursuant to these laws and regulations and the permits issued under them. We may be required to make significant capital and operating expenditures on an ongoing basis, or to perform remedial or other corrective actions in connection with our projects, to comply with the requirements of these environmental laws and regulations or the terms or conditions of our permits. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil or criminal penalties, the imposition of investigatory or remedial obligations, and the issuance of orders limiting or prohibiting some or all of our operations. In addition, we may experience delays in obtaining or be unable to obtain required environmental regulatory permits or approvals, which may delay or interrupt our operations and limit our growth and revenue.

Our operations inherently risk incurring significant environmental costs and liabilities due to the need to manage waste from our processing facilities. Spills or other releases of regulated substances, including spills and releases that occur in the future, could expose us to material losses, expenditures and liabilities under applicable environmental laws, rules and regulations. Under certain of such laws and regulations, we could be held strictly liable for the removal or remediation of previously released materials or property contamination, regardless of whether we were responsible for the release or contamination and even if our operations met previous standards in the industry at the time they were conducted. In connection with certain acquisitions, we could acquire, or be required to provide indemnification against, environmental liabilities that could expose us to material losses. In addition, claims for damages to persons or property, including natural resources, may result from the EHS impacts of our operations. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us.

Environmental laws and regulations have changed rapidly in recent years and generally have become more stringent over time, and we expect this trend to continue. The most material of these changes relate to the control of air emissions from the combustion equipment we use to generate electricity from LFG. Such equipment, including internal combustion engines, are subject to stringent federal and state permitting and air emissions requirements. California has taken an aggressive approach to setting standards for engine emissions, and standards have been discussed that would be too high for us to be able to operate our equipment in that state. If California were to enact such standards or other states were to follow its lead, we could face challenges in maintaining our operations in such jurisdictions.

Continued government and public emphasis on environmental issues can be expected to result in increased future investments for environmental controls at our plants. Present and future environmental laws and regulations, and interpretations of those laws and regulations, applicable to our operations, more vigorous enforcement policies and discovery of currently unknown conditions may require substantial expenditures that could have a material adverse effect on our results of operations and financial condition. In January 2021, the current U.S. presidential administration signed multiple executive orders related to the climate and environment. These executive orders

direct federal agencies to review and reverse more than one-hundred actions taken by the previous U.S. presidential administration on the environment, instruct the Director of National Intelligence to prepare a national intelligence estimate on the security implications of the climate crisis and direct all agencies to develop strategies for integrating climate considerations into their international work, establish the National Climate Task Force which assembles leaders from across twenty-one federal agencies and departments, commit to environmental justice and new, clean infrastructure projects, commence development of emissions reduction targets and establish the special presidential envoy for climate on the National Security Council. At this time, we cannot predict the outcome of any of these executive actions on our operations.

Liabilities and costs associated with hazardous materials and contamination and other environmental conditions may require us to conduct investigations or remediation at the properties underlying our projects, may adversely impact the value of our projects or the underlying properties and may expose us to liabilities to third parties.

We may incur liabilities for the investigation and cleanup of any environmental contamination at the properties underlying or adjacent to our projects, or at off-site locations where we arrange for the disposal of hazardous substances or wastes. Under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 and other federal, state and local laws, an owner or operator of a property may become liable for costs of investigation and remediation, and for damages to natural resources. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release of such hazardous substances or whether the conduct giving rise to the release was legal at the time when it occurred. In addition, liability under certain of these laws is joint and several, which means that we may be assigned liabilities for hazardous substance conditions that exceed our action contributions to the contamination conditions. We also may be subject to related claims by private parties alleging property damage and personal injury due to exposure to hazardous or other materials at or from those properties. We may incur substantial investigation costs, remediation costs or other damages, thus harming our business, financial condition and results of operations, as a result of the presence or release of hazardous substances at locations where we operate or as a result of our own operations.

The presence of environmental contamination at a project may adversely affect an owner’s ability to sell such project or borrow funds using the project as collateral. To the extent that an owner of the real property underlying one of our projects becomes liable with respect to contamination at the real property, the ability of the owner to make payments to us may be adversely affected.

We may also face liabilities in cases of exposure to hazardous materials, and claims for such exposure can be brought by any third party, including workers, employees, contractors and the general public. Claims can be asserted by such persons relating to personal injury or property damage, and resolving such claims can be expensive and time consuming, even if there is little or no basis for the claim.

We have significant customer concentration, with a limited number of purchasers accounting for a substantial portion of our revenues.

There are a limited number of possible purchasers for energy. Because our projects depend on sales of electricity, RNG, RECs and RINs to certain key purchasers, our projects are highly dependent upon these power purchasers fulfilling their contractual obligations under their respective PPAs or GSAs. For 2020, sales to 10 customers represented approximately 77% of our aggregate revenues. Our projects’ purchasers may not comply with their contractual payment obligations or may become subject to insolvency or liquidation proceedings during the term of the relevant contracts and, in such event, we may not be able to find another purchaser on similar or favorable terms or at all. In addition, we are exposed to the creditworthiness of our purchasers and there is no guarantee that any purchaser will maintain its credit rating, if any. To the extent that any of our projects’ customers are, or are controlled by, governmental entities, our projects may also be subject to legislative or other political action that impairs their contractual performance. Failure by any key purchasers to meet its contractual commitments or the insolvency or liquidation of one or more of our purchasers could have a material adverse effect on our business, financial condition and results of operations.

The demand for RNG, Environmental Attributes and renewable electricity depends in part on mandates instituted voluntarily by our private-sector purchasers, which may change in the future in ways that negatively affect our business.

Various utilities are required by law and regulatory mandate to include RNG in their systems. In addition, some of our private-sector purchasers have voluntarily instituted renewable electricity mandates that drive their demand for RNG. If current and potential purchasers of our RNG are forced to adopt new policies or procedures in procuring RNG, or voluntarily adopt new or modified policies related to renewable energy procurement, we may not be able to renew our off-take agreements with pricing at historical levels or enter into new off-take agreements at all, which would adversely affect our results of operations.

Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in developing and operating our projects, which could damage our reputation, adversely affect our partner relationships or adversely affect our growth.

Our success depends on our ability to develop and operate projects in a timely manner, which depends in part on the ability of third parties to provide us with timely and reliable products and services. In developing and operating our projects, we rely on products meeting our design specifications and components manufactured and supplied by third parties, and on services performed by subcontractors. We also rely on subcontractors to perform substantially all of the construction and installation work related to our projects, and we often need to engage subcontractors with whom we have no experience.

If any of our subcontractors are unable to provide services that meet or exceed our customers’ expectations or satisfy our contractual commitments, our reputation, business and operating results could be harmed. In addition, if we are unable to avail ourselves of warranties and other contractual protections with providers of products and services, we may incur liability to our customers or additional costs related to the affected products and services, which could adversely affect our business, financial condition and results of operations. Moreover, any delays, malfunctions, inefficiencies or interruptions in these products or services could adversely affect the quality and performance of our projects and require considerable expense to find replacement products and to maintain and repair our projects. This could cause us to experience interruption in our production and distribution of renewable energy and generation of related Environmental Attributes, difficulty retaining current relationships and attracting new relationships, or harm our brand, reputation or growth.

Maintenance, expansion and refurbishment of LFG facilities involve significant risks that could result in unplanned outages or reduced output.

Our facilities may require periodic upgrading and improvement. Any unexpected operational or mechanical failure, including failure associated with breakdowns and forced outages, could reduce our facilities’ generating capacity below expected levels, reducing our revenues and jeopardizing our ability to pay dividends to holders of our Class A common stock at projected levels or at all. Unanticipated capital expenditures associated with maintaining, upgrading or repairing our facilities may also reduce profitability. If we make any major modifications to our facilities, such modifications could likely result in substantial additional capital expenditures. We may also choose to repower, refurbish or upgrade our facilities based on our assessment that such activity will provide adequate financial returns. Such facilities require time for development and capital expenditures before commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs, timing, available financing and future power and RNG prices. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We currently own, and in the future may acquire, certain assets in which we have limited control over management decisions and our interests in such assets may be subject to transfer or other related restrictions.

We own, and in the future may acquire, certain projects in joint ventures. Our current joint venture projects include our Sunshine Canyon and Mavrix projects. We are the operating partner for some of these projects while our joint venture partner is the operating partner in others. In the future, we may invest in other projects with a joint venture partner. Joint ventures inherently involve a lesser degree of control over business operations, which could result in an increase in the financial, legal, operational or compliance risks associated with a project, including, but not limited to, variances in accounting internal control requirements. Our co-venture partners may not have the level of experience, technical expertise, human resources management and other attributes necessary to operate these

assets optimally. To the extent we do not have a controlling interest in a project, our joint venture partners could take actions that decrease the value of our investment and lower our overall return. In addition, conflicts of interest may arise in the future between our company and our stockholders, on the one hand, and our joint venture partners, on the other hand, where our joint venture partners’ business interests are inconsistent with our and our stockholders’ interests. Further, disagreements or disputes between us and our joint venture partners could result in litigation, which could increase our expenses and potentially limit the time and effort our officers and directors are able to devote to our business, all of which could have a material adverse effect on our business, financial condition and results of operations. The approval of our joint venture partners also may be required for us to receive distributions of funds from assets or to sell, pledge, transfer, assign or otherwise convey our interest in such assets. Alternatively, our joint venture partners may have rights of first refusal or rights of first offer in the event of a proposed sale or transfer of our interests in such assets. These restrictions may limit the price or interest level for our interests in such assets, in the event we want to sell such interests.

Certain of our facilities are newly constructed or are under construction and may not perform as we expect.

We have a number of projects under construction that will begin production over the next 12 months. Therefore, our expectations of the operating performance of these facilities are based on assumptions and estimates made without the benefit of operating history. Our projections with respect to our new and developing projects, and related estimates and assumptions, are based on limited or future operating history. These facilities also include digesters under development for which we have no operating history. The ability of these facilities to meet our performance expectations is subject to the risks inherent in newly constructed energy generation and RNG production facilities and the construction of such facilities, including delays or problems in construction, degradation of equipment in excess of our expectations, system failures, and outages. The failure of these facilities to perform as we expect could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are subject to risks associated with litigation or administrative proceedings that could materially impact our operations, including proceedings in the future related to projects we subsequently acquire.

We are subject to risks and costs, including potential negative publicity, associated with lawsuits and, in particular, with respect to environmental claims and lawsuits or claims contesting the construction or operation of our projects. The result of and costs associated with defending any such lawsuit, regardless of the merits and eventual outcome, may be material and could have a material adverse effect on our operations. In the future, we may be involved in legal proceedings, disputes, administrative proceedings, claims and other litigation that arise in the ordinary course of business related to a project that we subsequently acquire. For example, individuals and interest groups may sue to challenge the issuance of a permit for a project or seek to enjoin construction or operation of a project. We may also become subject to claims from individuals who live in the proximity of our projects based on alleged negative health effects related to our operations. In addition, we have been and may subsequently become subject to legal proceedings or claims contesting the construction or operation of our projects.

Additionally, holders of purported intellectual property rights relating to our biogas development or treatment business or projects or any other technology relevant to our business may also initiate legal proceedings alleging infringement or misappropriation of such rights by us or our employees, either with respect to our own intellectual property or intellectual property that we license from third parties. For example, an industry participant previously brought a lawsuit against Archaea and two of its engineering employees in the Court of Chancery of the State of Delaware alleging, among other things, that the two employees (who are former employees of the industry participant) misappropriated trade secrets concerning strategy, financial data, highly technical equipment and product design and performance, product and project troubleshooting, competitive advantages, competitive disadvantages and future plans for development for the benefit of Archaea. The parties involved have settled this lawsuit on terms that are confidential, and this lawsuit has been dismissed with prejudice. “Business — Legal Proceedings” for more information about this dismissed lawsuit.

Any such legal proceedings or disputes could delay our ability to complete construction of a project in a timely manner or at all, or materially increase the costs associated with commencing or continuing commercial operations at a project. Settlement of claims and unfavorable outcomes or developments relating to these proceedings or disputes, such as judgments for monetary damages, injunctions or denial or revocation of permits, could have a material adverse effect on our ability to implement our growth strategy and, ultimately, our business, financial condition and results of operations.

We may in the future use hedging arrangements to mitigate certain risks, but the use of such derivative instruments could have a material adverse effect on our results of operations.

We are likely in the future to use interest rate swaps to manage interest rate risk. In addition, we may use transmission congestion contracts, forward energy sales and other types of hedging contracts, including foreign currency hedges if we do expand into other countries. If we elect to enter into such hedges, the related asset could recognize financial losses on these arrangements as a result of volatility in the market values of the underlying asset or if a counterparty fails to perform under a contract. If actively quoted market prices and pricing information from external sources are not available, the valuation of these contracts would involve judgment or the use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of these contracts. If the values of these financial contracts change in a manner that we do not anticipate, or if a counterparty fails to perform under a contract, it could harm our business, financial condition, results of operations and cash flows.

The concentration in revenues from and the geographic concentration of our projects expose us to greater risks of production interruptions from severe weather or other interruptions of production or transmission.

A substantial portion of our revenues are generated project sites in New York and Pennsylvania. A lengthy interruption of production or transmission of renewable energy from one or more of these projects, as a result of a severe weather event, failure or degradation of our or a landfill operator’s equipment or interconnection transmission problems could have a disproportionate effect on our revenues and cash flow as further described below. Regional events, such as gas transmission interruptions, regional availability of replacement parts and service in the event of equipment failures and severe weather events in either of those geographic regions could adversely affect our RNG production and transmission more than if our projects were more geographically diversified.

Our PPAs, fuel-supply agreements, RNG off-take agreements and other agreements contain complex price adjustments, calculations and other terms based on gas price indices and other metrics, the interpretation of which could result in disputes with counterparties that could affect our results of operations and customer relationships.

Certain of our PPAs, fuel supply agreements, RNG off-take agreements and other agreements require us to make payments or adjust prices to counterparties based on past or current changes in gas price indices, project productivity or other metrics and involve complex calculations. Moreover, the underlying indices governing payments under these agreements are subject to change, may be discontinued or replaced. The interpretation of these price adjustments and calculations and the potential discontinuation or replacement of relevant indices or metrics could result in disputes with the counterparties with respect to these agreements. Any such disputes could adversely affect project revenues, expense margins, customer or supplier relationships, or lead to costly litigation, the outcome of which we would be unable to predict.

We have a history of accounting losses and may incur additional losses in the future.

Archaea has incurred net losses since its formation in November 2018, including a net loss of $10 million for the six months ended June 30, 2021 and $2 million for the year ended December 31, 2020. Aria has also incurred net losses in recent historical periods, including a net loss of $30 million for the year ended December 31, 2020. We may incur losses in future periods, and we may never sustain profitability, either of which would adversely affect our business, prospects and financial condition and may cause the price of our common stock to fall. Furthermore, historical losses may not be indicative of future losses due to the unpredictability of the COVID-19 pandemic, and our future losses may be greater than our past losses. In addition, to try to achieve or sustain profitability, we may choose or be forced to take actions that result in material costs or material asset or goodwill impairments. We review our assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable, and we perform a goodwill impairment test on an annual basis and between annual tests in certain circumstances, in each case in accordance with applicable accounting guidance and as described in the financial statements and related notes included in this report. Changes to the use of our assets, divestitures, changes to the structure of our business, significant negative industry or economic trends, disruptions to our operations, inability to effectively integrate any acquired businesses, further market capitalization declines, or other similar actions or conditions could result in additional asset impairment or goodwill impairment charges or other adverse consequences, any of which could have material negative effects on our financial condition, our results of operations and the trading price of our common stock.

Loss of our key management could adversely affect performance and the value of our common shares.

We are dependent on the efforts of our key management. Although we believe qualified replacements could be found for any departures of key executives, the loss of their services could adversely affect our performance and the value of our common shares.

Risks Relating to the Business Combinations

Although we expect that the Business Combinations will produce substantial synergies, the integration of the two Companies, with different business cultures and compensation structures, presents significant management challenges. There can be no assurance that this integration, and the synergies expected to result from that integration, will be achieved as rapidly or to the extent currently anticipated.

The Business Combinations involve the integration of two businesses that operated as independent businesses prior to the Closing. The Company will be required to devote management attention and resources to integrating the Companies’ business practices and operations following the Closing. The Company may encounter potential difficulties in the integration process, including the following:

•        the inability to successfully integrate the two businesses, including operations and technologies, in a manner that permits the Company to achieve the cost savings and operating synergies anticipated to result from the Business Combinations, which could result in the anticipated benefits of the Business Combinations not being realized partly or wholly in the time frame currently anticipated or at all;

•        the loss of customers as a result of certain customers of either or both of the Companies deciding not to continue to do business with the Company, or deciding to decrease their amount of business in order to reduce their reliance on a single company;

•        the necessity of coordinating geographically separated organizations, systems and facilities;

•        potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the Business Combinations;

•        the integration of personnel with diverse business backgrounds and business cultures;

•        the consolidation and rationalization of information technology platforms and administrative infrastructures as well as accounting systems and related financial reporting activities;

•        the potential weakening of relationships with regulators; and

•        the challenge of preserving important relationships of the Companies and resolving potential conflicts that may arise.

Furthermore, it is possible that the integration process could result in the loss of talented employees or skilled workers of the Companies. The loss of talented employees and skilled workers could adversely affect the Company’s ability to successfully conduct business because of such employees’ experience and knowledge of the Companies’ respective business. In addition, the Company could be adversely affected by the diversion of management’s attention and any delays or difficulties encountered in connection with the integration of the Companies. The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of the businesses. If the Company experiences difficulties with the integration process, the anticipated benefits of the Business Combinations may not be realized fully or at all, or may take longer to realize than expected. These integration matters could have an adverse effect on the business, results of operations, financial condition or prospects of the Company during this transition period and for an undetermined period following the Closing.

Some relationships with customers and suppliers may experience disruptions in connection with the Business Combinations, which may limit our business.

Parties with which the Companies did business or with which we may do business in the future, including customers and suppliers, may experience uncertainty associated with the Business Combinations, including with respect to current or future business relationships with the Company. As a result, our business relationships may be subject to disruptions if customers, suppliers or others attempt to negotiate changes in existing business relationships

or consider entering into business relationships with parties other than the Company. These disruptions could harm relationships with existing third parties with whom the Companies had relationships and preclude the Company from attracting new third parties, all of which could have a material adverse effect on the Company’s business, financial condition and results of operations, cash flows, and/or share price.

We may incur successor liabilities due to conduct arising prior to the completion of the Business Combinations.

We may be subject to certain liabilities of the Companies. The Companies may have become subject to litigation claims in the operation of its business, including, but not limited to, with respect to employee matters and contract matters prior to the Closing. We may also be subject to intellectual property infringement, misappropriation or invalidity/non-infringement claims from third parties relating to conduct of the Companies prior to the Closing, and some of these claims may lead to litigation. Any litigation may be expensive and time-consuming and could divert management’s attention from its business and negatively affect its operating results or financial condition. The outcome of any litigation cannot be guaranteed and adverse outcomes can affect the Company.

We may be required to take write-downs or write-offs, or we may be subject to restructuring, impairment or other charges that could have a significant negative effect on our financial condition, results of operations and the price of the Offered Securities, which could cause you to lose some or all of your investment.

Although RAC conducted due diligence on the Companies, this diligence may not have revealed all material issues that may be present with the Companies’ respective business. As a result of these factors, we may be forced to later write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in the Company reporting losses. Even if RAC’s due diligence successfully identified certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with RAC’s preliminary risk analysis. Even though these charges may be non-cash items and therefore not have an immediate impact on our liquidity, the fact that we report charges of this nature could contribute to negative market perceptions about us or our securities. In addition, charges of this nature may cause us to be unable to obtain future financing on favorable terms or at all.

Risks Relating to Ownership of the Offered Securities

The market price of the Offered Securities may be volatile.

Fluctuations in the price of the Company’s securities could contribute to the loss of all or part of your investment. Prior to the Closing, there was not a public market for the stock of either of the Companies. Accordingly, the valuation ascribed to the Company in the Business Combinations may not be indicative of the price that will prevail in the trading market following the Closing.

If an active market for the Company’s securities develops and continues, the trading price of the Company’s securities could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Price volatility may be greater if the public float and/or trading volume of the Class A Common Stock is low.

Any of the factors listed below could have a material adverse effect on your investment in our securities and the Company’s securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of the Company’s securities may not recover and may experience a further decline. Factors affecting the trading price of the Company’s securities may include:

•        actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to the Company;

•        changes in the market’s expectations about the Company’s operating results;

•        success of competitors;

•        lack of adjacent competitors;

•        the Company’s operating results failing to meet the expectation of securities analysts or investors in a particular period;

•        changes in financial estimates and recommendations by securities analysts concerning the Company or the industries in which the Company operates in general;

•        operating and stock price performance of other companies that investors deem comparable to the Company;

•        announcements by the Company or its competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments;

•        changes in laws and regulations affecting the Company’s business;

•        commencement of, or involvement in, litigation involving the Company;

•        changes in the Company’s capital structure, such as future issuances of securities or the incurrence of additional debt;

•        the volume of shares of Class A Common Stock available for public sale;

•        any significant change in the Board or management;

•        sales of substantial amounts of Common Stock by our directors, executive officers or significant stockholders or the perception that such sales could occur;

•        general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism; and

•        changes in accounting standards, policies, guidelines, interpretations or principles.

Broad market and industry factors may materially harm the market price of our securities irrespective of our operating performance. The stock market in general and the NYSE have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If the Company is involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from the Company’s business regardless of the outcome of such litigation.

If the Business Combinations’ benefits do not meet the expectations of financial analysts, the market price of the Class A Common Stock may decline.

The market price of the Class A Common Stock may decline if the Company does not achieve the perceived benefits of the Business Combinations as rapidly as financial analysts expect or if the effect of the Business Combinations on the Company’s financial results is not consistent with the expectations of financial analysts. Accordingly, holders of Class A Common Stock may experience a loss as a result of a decline in the market price of the Class A Common Stock. In addition, a decline in the market price of Class A Common Stock could adversely affect the Company’s ability to issue additional securities and to obtain additional financing in the future.

The NYSE may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject the Company to additional trading restrictions.

Currently, the Class A Common Stock and the Public Warrants are traded on the NYSE. However, we cannot assure you that our securities will continue to be listed on the NYSE in the future. In order to continue listing its securities on the NYSE following the Closing, the Company is required to maintain certain financial, distribution and stock price levels. Generally, the Company is required to maintain a minimum market capitalization (generally $50,000,000) and a minimum number of holders of its securities (generally 300 public holders).

If the NYSE delists our securities from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect the Company’s securities could be quoted on an over-the-counter market. If this were to occur, the Company could face significant material adverse consequences, including:

•        a limited availability of market quotations for our securities;

•        reduced liquidity for our securities;

•        a determination that the Class A Common Stock is a “penny stock,” which will require brokers trading in the Class A Common Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

•        a limited amount of news and analyst coverage; and

•        a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Since the Class A Common Stock and the Public Warrants are listed on the NYSE, they are covered securities. If the Company is no longer listed on the NYSE, its securities would not be covered securities and it would be subject to regulation in each state in which it offers its securities.

Because there are no current plans to pay cash dividends on the Common Stock for the foreseeable future, you may not receive any return on investment unless you sell your Class A Common Stock for a price greater than that which you paid for it.

We intend to retain future earnings, if any, for future operations, expansion and debt repayment, and there are no current plans to pay any cash dividends for the foreseeable future. The declaration, amount and payment of any future dividends on shares of Common Stock will be at the sole discretion of the Board, which may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions, implications on the payment of dividends by the Company to its stockholders or by its subsidiaries to it and such other factors as the Board may deem relevant. In addition, our ability to pay dividends is limited by covenants of any indebtedness it incurs or has incurred. As a result, you may not receive any return on an investment in the Common Stock unless you sell your shares of Common Stock for a price greater than that which you paid for it.

If securities analysts do not publish research or reports about our business or if they downgrade the Class A Common Stock or our sector, the price and trading volume of the Class A Common Stock could decline.

The trading market for the Class A Common Stock and the Warrants relies in part on the research and reports that industry or financial analysts publish about the Company or its business. We do not control these analysts. In addition, some financial analysts may have limited expertise with our operations. Furthermore, if one or more of the analysts who do cover us downgrade our stock or industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the Class A Common Stock price could decline. If one or more of these analysts ceases coverage of the Company or fails to publish reports on it regularly, we could lose visibility in the market, which in turn could cause our stock price or trading volume to decline.

Future sales, or the perception of future sales, by the Company or its stockholders in the public market could cause the market price for the Class A Common Stock to decline.

Pursuant to the terms of the Stockholders Agreement, the Aria Holders are subject to a 180-day lock-up period on transferring their equity interests in the Company, while the Archaea Holders are subject to a lock-up period (x) ending on the date that is the two-year anniversary of the Closing Date solely with respect to the Company Interests (as defined in the Stockholders Agreement) distributed by Archaea Energy LLC after the one-year anniversary of the Closing Date to the Archaea Holders who are members of management of the Company as of the Closing or their Affiliates (as defined in the Stockholders Agreement) and (y) ending on the date that is the one-year anniversary of the Closing Date with respect to all other Company Interests issued to the Archaea Holders at the Closing other than those described in the immediately foregoing clause (x). The lock-up restrictions applicable to the Aria Holders are subject to early expiration based on the per share trading price of Class A Common Stock as set forth in the Stockholders Agreement. See “Securities Act Restrictions on Resale of Securities — Lock-up Agreements” for further discussion. In addition, RAC’s former officers and directors and their affiliates have agreed with the Company, subject to certain exceptions, not to transfer or dispose of their Common Stock during the period from the date of the closing of the Business Combinations through the earlier of (i) the first anniversary of the consummation of the Business Combinations, (ii) the date that the closing price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations

and the like), for 20 trading days within any 30 trading day period following the 150th day following the Business Combinations and (iii) the consummation of a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

Upon the expiration or waiver of the lock-ups described above, shares held by such persons will be eligible for resale, subject to volume, manner of sale and other limitations under Rule 144, when such rule becomes applicable to the Company, or pursuant to the registration statement of which this prospectus forms a part. By selling a large number of shares, these stockholders could cause the prevailing market price of the Class A Common Stock to decline.

As restrictions on resale end or if these stockholders exercise their registration rights, the market price of the Class A Common Stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of shares of Class A Common Stock or other securities.

In addition, the shares of Class A Common Stock reserved for future issuance under Archaea Energy Inc. 2021 Omnibus Incentive Plan (the “2021 Plan”) will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting requirements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144. The number of shares of Class A Common Stock reserved for future issuance under its equity incentive plans is 11.3 million, which represented approximately 10% of the shares of Common Stock that was outstanding following the consummation of the Business Combinations. The Company will file one or more registration statements on Form S-8 under the Securities Act to register shares of Class A Common Stock or securities convertible into or exchangeable for shares of Class A Common Stock issued pursuant to the 2021 Plan. Accordingly, shares registered under such registration statements will be available for sale in the open market.

In the future, we may also issue securities in connection with investments or acquisitions. The amount of shares of Common Stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding shares of Common Stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to our stockholders.

We may redeem your unexpired Warrants prior to their exercise at a time that is disadvantageous to you, thereby making your Warrants worthless or otherwise causing you to exercise or sell your Warrants in a manner disadvantageous to you.

We have the ability to redeem outstanding Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided that the last reported sales price of our Class A Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which we give proper notice of such redemption and provided certain other conditions are met. If and when the Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. If we call the Warrants for redemption for cash as described above, our management 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 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, 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 our shares of 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 Warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Class A Common Stock per Warrant (subject to adjustment).

In addition, we may redeem your Warrants at any time after they become exercisable and prior to their expiration at a price of $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption, provided that holders will be able to exercise their warrants prior to redemption for a number of shares of our Class A Common Stock determined based on the redemption date and the fair market value of our Class A Common Stock,

if, and only if, the last reported sale price of our Class A Common Stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, reclassifications, recapitalizations and the like) on the trading day prior to the date we send the notice of redemption to the warrantholders. Please see “Description of Securities — Warrants — Public Warrants.” Any such redemption may have similar consequences to a cash redemption described above.

Redemption of the outstanding Warrants could force you (i) to exercise your Warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (ii) to sell your Warrants at the then-current market price when you might otherwise wish to hold your Warrants or (iii) to accept the nominal redemption price which, at the time the outstanding Warrants are called for redemption, is likely to be substantially less than the market value of your Warrants. In addition, the value received upon exercise of the Warrants may be less than the value you would have received if you had exercised your Warrants at a later time where the underlying stock price is higher and, in the event of cashless exercise, may not compensate you for the value of the Warrants because the number of shares of Class A Common Stock received is capped at 0.361 shares of Class A Common Stock per Warrant (subject to adjustment).

None of the Private Placement Warrants will be redeemable by us so long as they are held by the Sponsor, Atlas or their permitted transferees.

We may amend the terms of the Warrants in a manner that may be adverse to warrantholders. As a result, the exercise price of your Warrants could be increased, the Warrants could be converted into cash or stock (at a ratio different than initially provided), the exercise period could be shortened and the number of shares of Class A Common Stock purchasable upon exercise of a Warrant could be decreased, all without the approval of a warrantholder.

The Warrant Agreement provides that any modification or amendment thereto that adversely affects the interests of the holders of the Public Warrants shall require the vote or written consent of the registered holders of 50% of the then-outstanding Public Warrants, and any modifications or amendments to the terms of the Private Placement Warrants shall require the vote or written consent of the registered holders of 50% of the-then outstanding Private Placement Warrants. (The Warrant Agreement provides that the Forward Purchase Warrants have the same terms as the Public Warrants.) Accordingly, we may amend the terms of the Public Warrants or the Forward Purchase Warrants in a manner adverse to a holder thereof if holders of at least 50% of the then-outstanding Public Warrants approve of such amendment, and we may amend the terms of the Private Placement Warrants in a manner adverse to a holder thereof if holders of at least 50% of the then-outstanding Private Placement Warrants approve of such amendment. Although our ability to amend the terms of the Warrants with such consent is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Warrants, convert the Warrants into cash or stock (at a ratio different than initially provided), shorten the exercise period or decrease the number of shares of our Class A Common Stock purchasable upon exercise of a Warrant.

Our ability to require holders of the Warrants to exercise their Warrants on a cashless basis after we call the Warrants for redemption or if there is no effective registration statement covering the Class A Common Stock issuable upon exercise of these Warrants will cause holders to receive fewer shares of Class A Common Stock upon their exercise of the Warrants than they would have received had they been able to pay the exercise price of their Warrants in cash.

If the shares of Class A Common Stock are at the time of any exercise of a Warrant not listed on a national securities exchange such that the shares of Class A Common Stock satisfy the definition of a “covered security” under Section 18(b)(I) of the Securities Act, we may, at our option, require holders of Public Warrants or Forward Purchase Warrants who exercise their Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event we so elect, we will not be required to file or maintain in effect a registration statement, but we will be required to use our best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. In addition, during any period when we shall have failed to maintain an effective registration statement, warrantholders may exercise Warrants on a cashless basis. “Cashless exercise” means the warrantholder pays the exercise price by giving up some of the shares for which the warrant is being exercised, with those shares valued at the then current market price. Accordingly, each holder would pay the exercise price by surrendering the 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,

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” shall mean volume weighted average price of our Class A Common Stock as reported during 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 Warrants.

If we choose to require holders to exercise their Warrants on a cashless basis, which we may do at our sole discretion, or if holders elect to do so in the event there is no effective registration statement, the number of shares of Class A Common Stock received by a holder upon exercise will be fewer than it would have been had such holder exercised their Warrants for cash. For example, if the holder is exercising 875 Public Warrants at $11.50 per share through a cashless exercise when the shares of Class A Common Stock have a fair market value per share of $17.50 per share, then upon the cashless exercise, the holder will receive 300 shares of Class A Common Stock, whereas the holder would have received 875 shares of Class A Common Stock if the exercise price was paid in cash. This will have the effect of reducing the potential upside of the holder’s investment because the holder will hold a smaller number of shares of Class A Common Stock upon a cashless exercise of the Warrants they hold.

Anti-takeover provisions in our Amended and Restated Certificate of Incorporation and bylaws could delay or prevent a change of control.

Certain provisions of the Amended and Restated Certificate of Incorporation and bylaws may have an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by the Company’s stockholders.

These provisions, among other things:

•        establish a staggered board of directors divided into three classes serving staggered three-year terms, such that not all members of the Board will be elected at one time;

•        authorize the Board to issue new series of preferred stock without stockholder approval and create, subject to applicable law, a series of preferred stock with preferential rights to dividends or our assets upon liquidation, or with superior voting rights to the existing Common Stock;

•        eliminate the ability of stockholders to call special meetings of stockholders;

•        eliminate the ability of stockholders to fill vacancies on the Board;

•        establish advance notice requirements for nominations for election to the Board or for proposing matters that can be acted upon by stockholders at annual stockholder meetings;

•        permit the Board to establish the number of directors;

•        provide that the Board is expressly authorized to make, alter or repeal our bylaws;

•        provide that stockholders can remove directors only for cause; and

•        limit the jurisdictions in which certain stockholder litigation may be brought.

These anti-takeover provisions could make it more difficult for a third-party to acquire the Company, even if the third party’s offer may be considered beneficial by many of the Company’s stockholders. As a result, the Company’s stockholders may be limited in their ability to obtain a premium for their shares. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause the Company to take other corporate actions you desire.

The Amended and Restated Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

The Amended and Restated Certificate of Incorporation provides that, that, unless the Company consents in writing to the selection of an alternative forum, the sole and exclusive forum, to the fullest extent permitted by law,

for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (3) any action asserting a claim against us or any director, officer, or other employee arising pursuant to the General Corporation Law of the State of Delaware (the “DGCL”), (4) any action to interpret, apply, enforce, or determine the validity of our amended and restated certificate of incorporation or bylaws, or (5) any other action asserting a claim that is governed by the internal affairs doctrine, shall be the Court of Chancery of the State of Delaware (or another state court or the federal court located within the State of Delaware if the Court of Chancery does not have or declines to accept jurisdiction), in all cases subject to the court’s having jurisdiction over indispensable parties named as defendants. In addition, the Amended and Restarter Certificate of Incorporation provides that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act but that the forum selection provision will not apply to claims brought to enforce a duty or liability created by the Exchange Act. Although we believe these provisions benefit the Company by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers. Alternatively, if a court were to find the choice of forum provision contained in the Amended and Restarter Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, financial condition, and operating results. For example, under the Securities Act, federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Any person or entity purchasing or otherwise acquiring any interest in the Company’s capital stock shall be deemed to have notice of and consented to this exclusive forum provision, but will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

Archaea identified material weaknesses in its internal control over financial reporting. If the Company is unable to remediate these material weaknesses, or if it identifies additional material weaknesses in the future or otherwise fails to maintain an effective system of internal controls, it may not be able to accurately or timely report its financial condition or results of operations, which may adversely affect the Company’s business and stock price.

In connection with the preparation and audit of Archaea’s consolidated financial statements for each of the years in the three-year period ended December 31, 2020, material weaknesses were identified in Archaea’s internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of its annual or interim consolidated financial statements will not be prevented, or detected and corrected, on a timely basis. These material weaknesses were as follows:

•        For various transactions and balances, the same person was the originator and preparer of financial information without further review by an independent person with sufficient accounting and/or financial reporting competence and authority; and

•        For certain general ledger accounts, no reconciliation was prepared, the documentation supporting reconciliations was not sufficient to enable an effective review by others, and/or there was insufficient analysis to review the contents of accounts to ensure the correctness of items recorded in the account.

These material weaknesses could result in a misstatement of substantially all of the Combined Company’s accounts or disclosures that would result in a material misstatement to the Combined Company’s annual or interim financial statements that would not be prevented or detected.

Archaea developed and executed a plan to remediate the material weaknesses described above in anticipation of the Closing, including the hiring of a Chief Financial Officer and a Chief Accounting Officer. When implemented, Archaea’s remediation plan included measures such as hiring additional accounting and financial reporting personnel with appropriate technical accounting knowledge and public company experience in financial reporting; designing and implementing formal processes, policies and procedures supporting Archaea’s financial close process, including creating standard balance sheet reconciliation templates and journal entry controls; and designing and implementing controls to formalize roles and review responsibilities to align with Archaea’s team’s skills and experience in designing and implementing formal controls over segregation of duties.

The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the possibility of human error and the risk of fraud. If we are unable to remediate Archaea’s material weaknesses, our ability to record, process and report financial information accurately, and to prepare financial statements within the time periods specified by the forms of the SEC, could be adversely affected which, in turn, may adversely affect our reputation and business and the market price of the Offered Securities. In addition, any such failures could result in litigation or regulatory actions by the SEC or other regulatory authorities, loss of investor confidence, delisting of our securities and harm to our reputation and financial condition, or diversion of financial and management resources from the operation of our business.

Our failure to timely and effectively implement controls and procedures required by Section 404(a) of the Sarbanes-Oxley could have a material adverse effect on our business.

We will be required in the future to provide management’s attestation on internal controls in accordance with applicable SEC guidance. The standards required for a public company under Section 404(a) of the Sarbanes-Oxley Act are significantly more stringent than those required of the Companies when they were privately-held companies. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that are applicable following the Closing. If the Company is not able to implement the additional requirements of Section 404(a) in a timely manner or with adequate compliance, it may not be able to assess whether its internal controls over financial reporting are effective, which may subject it to adverse regulatory consequences and could harm investor confidence and the market price of its securities.

We are an emerging growth company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act, and we 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, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our shareholders may not have access to certain information they may deem important. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the market value of our Common Stock held by non-affiliates exceeds $700 million as of any June 30 before that time, in which case we would no longer be an emerging growth company as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

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 a 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 election to opt out is irrevocable. We have 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, we, 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 comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used.
