Our ability to generate revenue from our sale of RNG or our generation and sale of Environmental Credits depends on many factors, including the markets for RNG as a vehicle fuel and for Environmental Credits. The markets for Environmental Credits have been volatile and unpredictable in recent periods, and the prices for these credits are subject to fluctuations (see “Our Principal Products, Services and Other Business Activities—Sales of Environmental Credits” in Part I, Item 1 of our Annual Report on Form 10-K filed with the SEC on February 24, 2025 (the “Annual Report”) for more information on the fluctuations in 2024). Additionally, the value of Environmental Credits, and consequently the revenue levels we may receive from our sale of these credits, may be adversely affected by changes to the federal and state programs under which these credits are generated and sold, such as any adverse impacts from the OBBBA, prices for and use of oil, diesel or gasoline, the inclusion of additional qualifying fuels in the programs, increased production and use of other fuels in the programs, or other conditions. Our ability to generate revenue from sales of Environmental 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 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 restricted, permanently limited, or lost entirely, and we could also be subject to fines or other sanctions. Any of these outcomes could force us to purchase credits in the open market to cover any credits we have contracted to sell, retire credits we may have generated but not yet sold, reduce or eliminate a significant revenue stream, or incur substantial additional and unplanned expenses. Any permanent or temporary discontinuation or suspension of federal and state programs that provide credits, grants and incentives, such as the AFTC, which expired on December 31, 2024 and has not been renewed, or the Section 45Z Production Tax Credit would also adversely impact our revenue. Moreover, in the absence of programs that allow us to generate and sell Environmental Credits or other federal and state programs that support the RNG vehicle fuel market, or if our customers are not willing to pay a premium for RNG, we may be unable to operate our RNG business profitably or at all.

In addition, other factors related to the development and operation of renewable energy projects could adversely affect our business, including: changes in pipeline gas quality standards or other regulatory changes that may limit our ability to transport RNG on pipelines for delivery to vehicles or increase the costs of processing RNG to allow for such deliveries; construction risks, including the risk of delay, that may arise because of inclement weather, natural disasters, accidents, labor disruptions, disputes, or increases in costs for or shortages of equipment and construction materials; operating risks; weather conditions; financial condition of the applicable source owner, including obstacles to their ability to adequately fund their operations or pay vendors and creditors; health of the applicable dairy herd; consolidation in the dairy industry; budget overruns; possible liabilities because of unforeseen environmental, construction, technological or other complications; failures or delays in obtaining desired or necessary rights, including leases and feedstock agreements; diseases and health crises; and failures or delays in 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. Any of these factors could prevent completion or operation of projects, or otherwise adversely affect our business, financial condition, and results of operations.

Current wording

Our specific focus on RNG exposes us to risks related to the supply of and demand for RNG and Environmental Credits, the cost of capital expenditures, government regulation, including increased and/or new tariffs on equipment supply and raw materials, and economic conditions, among other factors. As an RNG supplier we may also be negatively affected by lower RNG production resulting from lack of feedstock, mechanical breakdowns, faulty technology, competitive markets, or changes to the laws and regulations that mandate the use of renewable energy sources. In addition, other factors related to the development and operation of renewable energy projects could adversely affect our business, including: changes in pipeline gas quality standards or other regulatory changes that may limit our ability to transport RNG on pipelines for delivery to vehicles or increase the costs of processing RNG to allow for such deliveries; construction risks, including the risk of delay, that may arise because of inclement weather, natural disasters, accidents, labor disruptions, disputes, or increases in costs for or shortages of equipment and construction materials; operating risks; weather conditions; financial condition of the applicable source owner, including obstacles to their ability to adequately fund their operations or pay vendors and creditors; health of the applicable dairy herd; consolidation in the dairy industry; budget overruns; possible liabilities because of unforeseen environmental, construction, technological or other complications; failures or delays in obtaining desired or necessary rights, including leases and feedstock agreements; diseases and health crises; and failures or delays in 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.

We have incurred pre-tax losses in the past, may incur losses in the future, and may never sustain profitability, any 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, 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. For instance, we have recorded significant charges in connection with our closure of certain fueling stations, our determination that certain assets were impaired because of the foregoing, and other actions. 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. For example, due to a decline in the market price of our common stock during the first quarter of 2025, we determined that an indicator of potential goodwill impairment existed and as such, we performed an interim goodwill impairment test of our single reporting unit and determined that the carrying value of the Company’s single reporting unit exceeded its fair value. A goodwill impairment loss for the Company’s single reporting unit was recognized in the amount of $64.3 million in the first quarter of 2025, which comprised the total amount of goodwill of the Company before giving effect to the impairment.

Increases, decreases and general volatility in oil, diesel, renewable diesel, natural gas, RNG and Environmental Credit prices could adversely affect our business.

Current wording

Increases, decreases and general volatility in the prices of RNG, natural gas, crude oil, diesel, renewable diesel and Environmental Credits could adversely affect our business.

Previous wording

The prices of RNG, natural gas, crude oil, diesel, renewable diesel, and Environmental Credits have been volatile, and this volatility may continue to increase. Factors that have, and may in the future, cause volatility in the prices of RNG, natural gas, crude oil, diesel, renewable diesel, and Environmental Credits include, among others, changes in supply and availability of crude oil, RNG and other renewable transportation fuels, and natural gas, government regulations, inventory levels, customer demand, price and availability of alternatives, weather conditions, negative publicity about crude oil or natural gas drilling, production or transportation techniques and methods, worldwide economic, military, health and political conditions, transportation costs and the price of foreign imports. If the prices of crude oil and diesel are low or decline, or if the price of RNG or natural gas increases without corresponding increases in the prices of crude oil and diesel or Environmental Credits, we may not be able to offer our customers an attractive price for our vehicle fuels, market adoption of our vehicle fuels could be slowed or limited and we may be forced to reduce the prices at which we sell our vehicle fuels in order to try to attract new customers or prevent the loss of demand from existing customers. Natural gas and crude oil prices are expected to remain volatile for the near future because of market uncertainties over supply and demand, including due to the state of the world economy, geopolitical conditions, tariffs, military conflicts such as the wars in Ukraine and the Middle East, energy infrastructure and other factors. Fluctuations in natural gas prices affect the cost to us of the natural gas commodity. High natural gas prices adversely affect our operating margins when we cannot pass the increased costs through to our customers. Conversely, lower natural gas prices reduce our revenue when the commodity cost is passed through to our customers.

The market for vehicle fuels is highly competitive. The biggest competition for our products is diesel because most vehicles in our key markets are powered by diesel. We also compete with suppliers of other alternative vehicle fuels, including renewable diesel, biodiesel, and ethanol, as well as producers and fuelers of alternative vehicles, including hybrid, electric and hydrogen-powered vehicles. Additionally, our stations compete directly with other natural gas fueling stations and indirectly with electric vehicle charging stations and fueling stations for other vehicle fuels. Many businesses are in the market for RNG and other alternatives for use as vehicle fuel, including alternative vehicle and alternative fuel companies, refuse collectors, industrial gas companies, private equity groups, commodity traders, truck stop and fuel station owners, fuel providers, gas marketers, utilities and their affiliates and other organizations. If the alternative vehicle fuel market grows, the number and type of participants in this market and their level of capital and other commitments to alternative vehicle fuel programs could increase. Many of our competitors have substantially greater customer bases, brand awareness and financial, marketing and other resources than we have. As a result, these competitors may be able to respond more quickly to changes in customer preferences, legal requirements or other industry or regulatory trends; devote greater resources to the development, promotion and sale of their products; adopt more aggressive pricing policies; dedicate more effort to infrastructure and systems development in support of their business or product development activities; implement more robust or creative initiatives to advance customer acceptance of their products; or exert more influence on the regulatory landscape that affects the vehicle fuels market. We expect competition to increase in the vehicle fuels market generally. In addition, if the demand for alternative vehicle fuels, including RNG, increases, then we expect competition to also increase. Any such increased competition may reduce our customer base and revenue and may lead to increased pricing pressure, reduced operating margins and fewer expansion opportunities.

Increased global cybersecurity threats and more sophisticated and targeted computer crime pose a risk to the security of our information systems and the confidentiality, availability and integrity of our data. There have been several recent, highly publicized cases in which organizations of various types and sizes have reported the unauthorized disclosure of customer or other confidential information, as well as cybersecurity incidents involving the dissemination, theft and destruction of corporate information, intellectual property, cash or other valuable assets. There have also been several highly publicized cases in which hackers have requested “ransom” payments in exchange for not disclosing customer or other confidential information or for not disabling the target company’s computer or other systems. Implementing security measures designed to prevent, detect, mitigate or correct these or other cybersecurity threats involves significant costs. Despite implementing security measures, we have, from time to time, experienced cyberattacks or other cybersecurity incidents that have threatened our data and information systems. It is possible that future cybersecurity incidents could materially and adversely affect our business. We cannot provide assurance that our safety and security measures will prevent our information systems from improper functioning or damage, or the improper access or disclosure of personally identifiable information such as in the event of cybersecurity incidents. Any Information Technology security threats that are successful against our security measures could, depending on their nature and scope, lead to the compromise of confidential information, improper use of our systems and networks, manipulation and destruction of data, operational disruptions, and substantial financial outlays. A cybersecurity incident could occur and persist for an extended period without detection, and an investigation of any successful cybersecurity incident would likely require significant time, costs and other resources to complete. We may be required to expend significant financial resources to protect against or to remediate such cybersecurity incidents. In addition, our information technology infrastructure and information systems are vulnerable to damage or interruption from natural disasters, power loss and telecommunications failures.

Additionally, the integration of Internet of Things (“IoT”) and Artificial Intelligence (“AI”) technologies into our business operations expose us to various operational, cybersecurity, and regulatory risks. The reliance on IoT and AI systems for critical business operations necessitates high levels of system reliability and performance. Any malfunction, failure, or suboptimal performance of these systems can disrupt business activities, resulting in downtime, reduced productivity, and financial losses. Inaccurate, incomplete, or corrupted data can lead to flawed decision-making, inefficiencies, and potential financial and operational risks. IoT and AI systems also increase our vulnerability to cybersecurity threats. Further, the use of IoT and AI technologies involves collecting and processing large volumes of personal and proprietary data. Any mishandling or unauthorized access to this data can result in privacy breaches, regulatory penalties, and loss of customer trust. The regulatory landscape for IoT and AI technologies is evolving rapidly. The Company must ensure compliance with existing and emerging regulations related to data protection, privacy, and cybersecurity. Non-compliance could result in significant legal and financial penalties and impact business operations.

As part of our business activities, we design and construct vehicle fueling stations that we either own and operate ourselves or sell to our customers. These activities require a significant amount of judgment in determining where to build and open fueling stations, including predictions about fuel demand that may not be accurate for any of the locations we target. As a result, we have built stations that we may not open for fueling operations, and we may open stations that fail to generate the volume or profitability levels we anticipate, either or both of which could occur due to a lack of sufficient customer demand at the station locations or for other reasons. For any stations that are completed but unopened, we would have substantial investments in assets that do not produce revenue, and for any stations that are open and underperforming, we may decide to close the stations. We have nearly completed stations that are not open for fueling operations. Some of these stations are subject to agreements that will expire prior to us being able to open such stations and, as a result, we will incur substantial additional costs and non-cash asset impairments or other charges to remove equipment located at such stations, which could cause the price of our common stock to decline. For example, our Liquified Natural Gas Fueling Station and LNG Master Sales Agreement with Pilot Travel Centers, LLC (“Pilot”) expired in August 2025 per its terms. In connection with the decision for non-renewal of the Pilot agreement, and subsequent removal of the station equipment and site improvements, the Company recognized $50.7 million, in the first quarter of 2025, associated with accelerated depreciation expense and incremental ARO charges.

We also face many operational challenges in connection with our station design and construction activities. For example, we may not be able to identify suitable locations for the stations we or our customers seek to build. Additionally, even if preferred sites can be located, we may encounter land use or zoning difficulties, problems with utility services, challenges obtaining and retaining required permits and approvals or local resistance, including due to reduced operations of permitting agencies because of health crises, any of which could prevent us or our customers from building new stations on these sites or limit or restrict the use of new or existing stations. Any such difficulties, resistance or limitations or any failure to comply with local permit, land use or zoning requirements could restrict our activities or expose us to fines, reputational damage or other liabilities, which would harm our business and results of operations. In addition, we act as the general contractor and construction manager for new station construction and facility modification projects, and we typically rely on licensed subcontractors to perform the construction work.

In addition to normal business risks, including the other risks discussed in these risk factors, our contracts with government entities are often subject to unique risks, some of which are beyond our control. For example, long-term government contracts and related orders are subject to cancellation if adequate appropriations for subsequent performance periods are not made. Further, the termination of funding for a government program supporting any of our government contracts or any other governmental action that results in reduced support for our government contracts could result in the loss of anticipated future revenue attributable to the contract. Moreover, government entities with which we contract are often able to modify, curtail or terminate contracts with us at their convenience and without prior notice, and would only be required to pay for work completed and commitments made at or prior to the time of termination.

Our performance in certain periods has also been affected by transactions or events that have resulted in significant cash or non-cash gains or losses. These or other similar gains or losses may not recur, in the same amounts or at all in future periods. These significant fluctuations in our operating results may render period-to-period comparisons less meaningful, such as with respect to periods heavily impacted by effects of the COVID-19 pandemic or periods impacted by non-cash asset impairment charges related to station closures, and investors in our securities should not rely on the results of one period as an indicator of performance in any other period. Additionally, these fluctuations in our operating results could cause our performance in any period to fall below the financial guidance we may have provided to the public or the estimates and projections of the investment community, which could negatively affect the price of our common stock.

Our business may be adversely impacted by a future pandemic or epidemic, such as the COVID-19 pandemic. For example, as a result of the COVID-19 pandemic, we experienced increased costs on equipment and construction services, and longer lead times on equipment and materials orders. Any future pandemic, epidemic, or infectious disease outbreak could also adversely affected our business through delaying the adoption of our RNG and natural gas vehicle fuels by heavy-duty trucks or delaying increased usage of our vehicle fuels; decreasing the volume of truck and fleet operations, including shuttle buses at airports, refuse trucks, and public transportation generally, and disrupting production of vehicles and engines that use our fuels.

Our future success is dependent on the services and performance of our executive officers and other key management, engineering, information technology, scientific, manufacturing and operating personnel. The loss of the services of any such personnel could materially adversely affect our business. Our ability to achieve our strategic plans will also depend on our ability to attract and retain additional qualified personnel. Recruiting key personnel in our industry is highly competitive and we cannot assure you that we will be able to do so. Our inability to attract and retain additional qualified personnel, or the departure of key employees, could materially and adversely affect our strategic plans and, therefore, our business, results of operations and financial condition. In addition, our inability to attract and retain sufficient personnel to quickly increase production at our facilities when and if needed to meet increased demand may adversely impact our ability to respond rapidly to any new product, growth or revenue opportunities.

In April 2026, Barclay F. Corbus, assumed the role of President and Chief Executive Officer, succeeding Andrew J. Littlefair. Leadership transitions, including changes in the Chief Executive Officer role, can create operational disruption, loss of institutional knowledge, employee attrition, shifts in strategic priorities and uncertainty among customers, suppliers, financing sources and employees. Such transitions may also require time for new leadership to establish relationships, implement strategic and operational changes, and align management teams and organizational processes. If we fail to manage leadership transitions effectively, including ensuring continuity of operations and execution during and following the Chief Executive Officer transition, our business, results of operations and liquidity could be adversely affected.

Asset sales and equity or debt financing may not be available when needed, on terms favorable to us or at all. Any sale of our assets to generate cash proceeds may limit our operational capacity and could limit or eliminate any revenue streams or business plans that are dependent on the sold assets. Any issuances of our common stock or securities convertible into our common stock to raise capital would dilute the ownership interest of our existing stockholders. Any additional debt financing we may pursue could require us to make significant interest or other payments. In addition, higher levels of indebtedness could increase our risk of non-repayment, adversely affect our creditworthiness, and amplify the other risks associated with our existing debt, which are discussed elsewhere in these risk factors. Further, we may incur substantial costs in pursuing any capital-raising transactions, including investment banking, legal and accounting fees. On the other hand, if we are unable to obtain capital in amounts sufficient to fund our obligations, expenses, and strategic initiatives, we could be forced to suspend, delay or curtail our business plans or operating activities or could default on our contractual commitments. Any such outcome could negatively affect our business, performance, liquidity, and prospects.

Current wording

We require capital to pay for capital expenditures, operating expenses, any mergers, acquisitions or strategic investments, capital calls related to our joint ventures, transactions or relationships we may pursue, and to make principal and interest payments on our indebtedness. If we cannot fund any of these activities with capital on-hand or cash provided by our operations, we may seek additional capital from other sources, such as by selling assets or pursuing debt or equity financing.

Our business is influenced by federal, state, and local tax credits, rebates, grants and other government programs and incentives that promote or exclude the use of our vehicle fuels. These include various government programs that make grant funds available from the purchase of vehicles and construction of fueling stations or dairy digesters, as well as the AFTC, which expired on December 31, 2024 and has not been renewed, under which we generated revenue for our vehicle fuel sales. For example, the One Big Beautiful Bill Act (the “OBBBA”), which was signed into law on July 4, 2025, includes a number of restrictions and additional requirements on the ability of taxpayers to claim or transfer certain tax credits historically claimed by the Company. Many of these additional requirements will be subject to future guidance issued by the U.S. Treasury Department. The effect of the OBBBA and any such subsequent guidance could impact our ability to claim such tax credits and may adversely impact our financial results. Additionally, our business is influenced by laws, rules and regulations that require reductions in carbon emissions and/or the use of renewable fuels, such as the programs under which we generate Environmental Credits.

challenges to agencies’ rules and regulations and their interpretations of such rules and regulations, and changes in federal, state or local political, social or economic conditions, including as a result of a lack of legislative focus on these programs and regulations or prolonged U.S. government shutdown, could result in their modification, delayed adoption or repeal. For example, the Inflation Reduction Act of 2022 (“IRA”) contains credits and tax incentives that have been and may in the future be beneficial to us but an executive order issued by President Trump in January 2025 (the “January 2025 Executive Order”) has paused disbursement of certain funds under the IRA and there can be no assurance that we will be able to continue to benefit from such credits and tax incentives in the future.

Current wording

These programs and regulations, which have the effect of encouraging the use of RNG as a vehicle fuel, have and could in the future expire or be repealed or amended for a variety of reasons. For example, parties with an interest in gasoline and diesel, electric or other alternative vehicles or vehicle fuels, including lawmakers, regulators, policymakers, environmental or advocacy organizations, producers of alternative vehicles or vehicle fuels, or other powerful groups, may invest significant time and money in efforts to delay, repeal or otherwise negatively influence regulations and programs that promote RNG. Many of these parties have substantially greater resources and influence than we have.

Federal or state laws, orders or regulations have been adopted, such as California’s AB 32 cap and trade law, and may in the future be adopted that impose limits on GHG emissions or otherwise require the adoption of zero-emission electric vehicles. The effects of GHG emission limits on our business are subject to significant uncertainties based on, among other things, the timing of any requirements, the required levels of emission reductions, the nature of any market-based or tax-based mechanisms adopted to facilitate reductions, the relative availability of GHG emission reduction offsets, the development of cost-effective, commercial-scale carbon capture and storage technology and supporting regulations and liability mitigation measures, the range of available compliance alternatives, and our ability to demonstrate that our vehicle fuels qualify as a compliance alternative under any statutory or regulatory programs to limit GHG emissions. If our vehicle fuels are not able to meet GHG emission limits or perform as well as other alternative fuels and vehicles, our solutions could be less competitive. Furthermore, additional federal or state taxes could be implemented on “tailpipe” emissions or on methane emissions generally, which would have a negative impact on the cost of our vehicle fuels, as compared to vehicle fuels that do not generate tailpipe emissions.

In June 2020, CARB adopted the Advanced Clean Trucks (the “ACT”) regulation, which requires manufacturers to sell a gradually increasing proportion of zero-emission electric trucks, vans and pickup trucks from 2024 onwards. By the year 2045, the ACT seeks to have every new commercial vehicle sold in California be zero-emissions. In April 2025, Congress voted to repeal the federal waiver for the ACT, and the State of California subsequently filed a lawsuit with the intent of preserving the regulation. The timing of resolution of the litigation is uncertain, and absent a legal victory, California will face difficulties in implementing any provisions of the ACT.

The timing of resolution of the litigation is uncertain, and absent a legal victory, California will face difficulties in implementing any provisions of the ACT. Further, in September 2020, the Governor of the State of California issued an executive order (the “September 2020 Executive Order”) providing that it shall be the goal of California that (i) 100% of in-state sales of new passenger cars and trucks will be zero-emission by 2035, (ii) 100% of medium- and heavy-duty vehicles in California will be zero-emission by 2045 for all operations, where feasible, and by 2035 for drayage trucks, and (iii) the state will transition to 100% zero-emission off-road vehicles and equipment by 2035 where feasible. The September 2020 Executive Order also directed CARB to develop and propose regulations and strategies aimed at achieving the foregoing goals. In June 2025, the Governor of the State of California issued an executive order following federal appeal of the ACT, reaffirming the State’s commitment to accelerate the deployment of zero-emission technologies, including passenger, medium, and heavy duty vehicles, consistent with the deployment targets and other actions directed in the 2020 Executive Order, to the extent consistent with state law and other requirements (the June 2025 Executive Order). In April 2023, CARB adopted the Advanced Clean Fleets (the “ACF”) regulation, which requires all public transit truck fleets, including municipal and other governments, be zero emission by 2042. The ACF regulation also sought to end the sale of combustion trucks in California in 2036. The ACF did not receive a federal EPA waiver and CARB chose to withdraw the ACF’s waiver application in January 2025. In September 2025, CARB repealed the ACF provisions concerning high-priority fleets and drayage vehicles. As it stands now, the ACF can only legally mandate state and local government fleets to purchase zero emission trucks which may be insufficient to sustain the manufacturing numbers required by the ACF over time.
