Item 1A. Risk Factors

Except as described below, there have been no material changes from the Risk Factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 17, 2025, as supplemented by our Quarterly Reports on Form 10-Q. The risks described in such reports are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

The financial performance of our business depends upon tax and other government incentives for the generation of RNG and Renewable Power, 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 governmental policies that support renewable generation and enhance the economic viability of owning Biogas Conversion Projects or Fueling Stations. These projects 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, Renewable Portfolio Standards (RPS) programs, modified accelerated cost-recovery system of depreciation and bonus depreciation. RNG specifically generates meaningful revenue through generation and monetization of Environmental Attributes provided for under several different programs, most commonly, RFS, LCFS and RPS.

Our provision for income taxes is subject to volatility and could be adversely affected by changes in tax laws or regulations, particularly changes in tax incentives in support of energy efficiency. The IRA contains extended and expanded clean energy tax credits such as ITCs, the Production Tax Credit ("PTC"), and created other financial incentives designed to promote the development of certain domestic clean energy projects. In order to receive the full value of such credits and incentives, our projects must satisfy a number of requirements including prevailing wage and apprenticeship requirements. If we fail to comply with these requirements, the value of the credits may be limited, and we may become subject to financial penalties. Uncertainty remains under the IRA on which types of projects are eligible for the tax credits and incentives and how projects can demonstrate compliance with the requirements, we may not receive full value of the tax credits and incentives, which could increase our income tax expense, reduce our net income and adversely impact the profitability of our projects or our ability to finance our projects. The U.S. Congress may look to alter or repeal various energy tax incentives included in the IRA, which could potentially impact projects in development or future project economics. Similarly, recent presidential executive orders directing the review and potential termination of funds appropriated through the IRA are also creating uncertainty of whether these financial incentives could be reduced or repealed in the future. Further, we maybe subject to risks arising from any limitations on the value or availability of tax incentives that benefit clean energy or fuel production, sales, or projects, such as the Section 45Z clean fuel production credit, ITCs, and the PTC, as seen in the accelerated termination of certain clean energy tax credits under the One Big Beautiful Bill the U.S. President signed into law on July 4, 2025, which may result in the reduction of such producers economic returns.

On November 17, 2023, the Treasury and the IRS proposed regulations regarding ITCs on renewable energy projects where the IRS specified certain types of RNG equipment are ineligible for ITCs which could negatively impact the profitability of our RNG business and our ability to finance our RNG projects. On February 16, 2024, the Treasury and the IRS released a correction to the proposed regulations clarifying that certain of such equipment may be eligible for ITCs. These regulations are merely proposed, and the Treasury and the IRS are collecting and reviewing comments received regarding the proposed regulations. The proposed regulations also contain provisions that we believe create uncertainty relating to the ownership, installation or modification of equipment and property on which ITCs can be claimed. If the final regulations are enacted in a form that limits, in whole or in part, the amount of ITCs for certain of our construction costs, this would reduce the amount of ITCs available and thus could have a material adverse effect on our operations and our business.

There is also uncertainty if IRA incentives may be reduced or repealed in the future, especially in light of the 2024 election results. In addition, the timing of when assets are placed in service has in the past and could in the future impact

our tax rate. If we experience unexpected delays in this timing, we may not be able to take advantage of ITCs as expected. If we are not able to utilize the ITCs as expected this could have an adverse effect of our financial results.

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 and 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 prospects. Such material adverse effects may result from decreased revenues, reduced economic returns on Biogas Conversion Projects and other potential future investments or joint ventures, increased financing costs, and/or difficulty obtaining financing.

If we are unable to utilize various federal, state and local governmental incentives to acquire additional Biogas Conversion Projects or Fueling Stations 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. In addition, we face similar risks with respect to the RFS program. Any future changes to, federal, state and local regulations and policies, including permitting requirements applicable to us, and enactment of new regulations and policies, may present technical, regulatory and economic barriers to the generation, purchase and use of Renewable Power and RNG, and may adversely affect the market for the associated Environmental Attributes. A failure on our part to comply with any laws, regulations or rules, applicable to us may adversely affect our business, investments and results of operations.
