PART I

ITEM 1. BUSINESS

OPAL Fuels Inc. (including its subsidiaries, the “Company,” “OPAL,” “we,” “us” or “our”) is a vertically integrated leader in the capture and conversion of biogas into low carbon intensity renewable natural gas ("RNG") and Renewable Power. OPAL Fuels is also a leader in the marketing and distribution of RNG to heavy duty trucking and other hard to de-carbonize industrial sectors. RNG is chemically identical to the natural gas used for cooking, heating homes and fueling natural gas engines, with one significant difference: RNG is produced by recycling methane emissions created by decaying organic waste as opposed to natural gas which is a fossil fuel pumped from the ground. We have participated in the biogas-to-energy industry for over 20 years.

Biogas is generated by microbes as they break down organic matter in the absence of oxygen. Biogas is comprised of non-fossil waste gas, with high concentrations of methane, which is the primary component of RNG and the source for combustion utilized by Renewable Power plants to generate electricity. Biogas can be collected and processed to remove impurities for use as RNG (a form of high-Btu fuel) and injected into existing natural gas pipelines as it is fully interchangeable with fossil fuel-based natural gas. Partially treated biogas can be used directly in heating applications (as a form of medium-Btu fuel) or in the production of Renewable Power. Our principal sources of biogas are (i) ~~landfill gas~~LFG, which is produced by the decomposition of organic waste at landfills, and (ii) dairy manure, which is processed through anaerobic digesters to produce the biogas.

We also design, develop, construct, operate and service Fueling Stations for trucking fleets across the country that use natural gas to displace diesel as their transportation fuel. We have participated in the alternative vehicle fuels industry for over a decade and have established an expanding network of Fueling Stations for dispensing RNG. In addition, we have recently begun implementing design, development, and construction services for hydrogen ~~fueling~~Fueling ~~stations~~Stations, and we are pursuing opportunities to diversify our sources of biogas to other waste streams.

Our Strategy

We aim to maintain and grow our position as a leading producer and dispenser of RNG in the United States and a leading provider of RNG to the heavy and medium-duty commercial vehicle market in the U.S. We support these objectives through a multi-pronged strategy of:

•Promoting the reduction of methane and ~~GHG~~greenhouse gases emissions and expanding the use of renewable fuels to displace fossil-based fuels: We share the renewable fuel industry’s commitment to providing sustainable renewable energy solutions and offering products with high economic and ecological value. By simultaneously replacing fossil-based fuels and reducing overall methane emissions, our projects have a positive environmental impact. We are committed to the sustainable development, deployment, and utilization of RNG to reduce the country’s dependence on fossil fuels. We strive to optimize the economics of capturing biogas from our host landfills and dairy farms for conversion to RNG by balancing the capital and operating costs with the current and future quality and quantity of biogas.

•Expanding our industry position as a full-service partner for development opportunities, including through strategic transactions: Throughout our over twenty years of biogas conversion experience, we have developed the full range of biogas conversion project related capabilities from ~~landfill~~LFG ~~gas~~ collection system expertise, to engineering, construction, management and operations, through environmental health and safety ("EHS") oversight and Environmental Attributes management. Our full suite of capabilities allows us to serve as a multi-project partner, including through strategic transactions.

•Expanding our capabilities to new feedstock sources and technologies: We believe we will be able to enter new markets for our products. With our experience and industry expertise, we believe we are well-positioned to take advantage of opportunities to meet the clean energy needs of other industries looking to use renewable energy in their operations both domestic and internationally. We are actively reviewing opportunities beyond our core LFG and dairy RNG business. Specifically, we intend to diversify our project portfolio beyond landfill biogas through the expansion into additional methane producing assets.

•Empowering our customers to achieve their sustainability and carbon reduction objectives: We are well positioned to empower our customers to achieve their sustainability and carbon reduction goals, by, for example, reducing GHG emissions from their commercial transportation activities, at a cost to customers that is competitive to other fuels, like diesel. We also assist our customers in their transition to cleaner transportation fuels by helping

~~fuels by helping~~ them obtain federal, state and local tax credits, grants and incentives, vehicle financing, and facilitating customer selection of vehicle specifications to meet their needs.

Vertical Integration of Business

Our combination of Biogas Conversion Projects and Fueling Stations, together with our dispensing, generation, and monetization of associated Environmental Attributes, differentiates us from our principal competitors. This vertical integration allows for a direct pathway to qualify biogas for Environmental Attributes and offers an attractive network of Fueling Stations to heavy and medium-duty trucking fleets running on natural gas.

Our involvement across the RNG value chain, from production to dispensing of RNG, gives us the opportunity to avoid value leakage that competitors may incur by having to rely upon third-parties for either RNG supply or dispensing. The additional value captured benefits us by allowing us to offer better terms to our transportation customers. The increasing adoption of RNG as a fuel for transportation use amongst our customers subsequently gives us more opportunities to secure additional gas rights for Biogas Conversion Projects.

Our vertical integration also attracts low carbon intensity ("CI") project developers that need partners to market and dispense their fuel to obtain Low Carbon Fuel Standard ("LCFS") credits and provide the required economic returns on their projects. As a result, we gain opportunities to source new Biogas Conversion Projects as well as secure RNG marketing agreements from these developers. In addition, fleet owners are attracted to our biogas conversion and dispensing resources which results in the growth of dispensing, station construction and service businesses.

Management and Project Expertise

Our management team has decades of combined experience in the design, development, construction, maintenance, and operation of Biogas Conversion Projects and Fueling Stations that dispense RNG, as well as the monetization of associated Environmental Attributes. We believe our team’s proven track record and focus give us a strategic advantage in continuing to grow our business. Our diverse experience and integration of key technical, environmental, and administrative support functions underpin our ability to design and operate projects and execute their day-to-day activities.

Our experience and existing project portfolio have provided access to a wide spectrum of available biogas-to-RNG and biogas-to-Renewable Power conversion technologies. We are technology agnostic and base project design on the available technologies (and related equipment) most suitable for the specific application, including membranes, media, and solvent-based gas cleanup technologies. We are actively engaged in the management of each project site and regularly serve in engineering, construction management, and commissioning roles. This allows us to develop a comprehensive understanding of the operational performance of each technology and how to optimize application of the technology to specific projects, including through enhancements and improvements of operating or abandoned projects. At LFG-to-RNG projects, technologies deployed at each project are relatively consistent and mature and management has extensive experience with such technologies. At livestock waste-to-RNG projects, digester technologies may be different from site to site, but upgrading technology is generally consistent from site to site and they have both been widely used in the past several decades. Additionally, we also work with key vendors on initiatives to develop and test upgrades to existing technologies. We apply our experience and knowledge to identify new sources of biogas.

We also have a network of experienced and creditworthy EPC contractors to perform design, development, procurement and construction services under our supervision. Typically, our contracts for EPC services contain fixed price, date certain provisions and liquidated damages provisions, which greatly reduce the risks typically associated with construction projects. ~~We also work with key vendors on initiatives to develop and test upgrades to existing technologies.~~

Access to Development Opportunities

We have many relationships throughout the industry supply chain including technology and equipment providers, feedstock owners and RNG off-takers. We believe the strong reputation we have attained and our understanding of the various and complex requirements for generating and monetizing Environmental Attributes gives us a competitive advantage relative to new market entrants. We further benefit from our vertical integration by offering dispensing and monetization services to third-party developers, which can lead to project acquisition or partnership opportunities for us.

We leverage our relationships built over the past several decades to identify and execute new project opportunities. Typically, new development opportunities come from our existing relationships with landfill owners and dairy developers who value our long operating history and strong reputation in the biogas conversion industry. This includes new projects and referrals from existing partners. We actively seek to extend the term of our contracts at project sites and ~~views~~view our

positive relationships with the owners and managers of host landfills and dairy farms as a contributing factor to our ability to extend contract terms as they come due.

Large and Diverse Project Portfolio

We have a large, technologically optimized Biogas Conversion Project portfolio. Our ability to solve complex project development challenges and integrate such solutions across our entire project portfolio has supported the long-term successful partnerships we have with our Biogas Conversion Project hosts. Because we are able to meet the varying needs of our host partners, we have a strong reputation and are actively sought out for new project and acquisition opportunities. Additionally, our size and financial discipline generally affords the ability to achieve priority service and pricing from contractors, service providers, and equipment suppliers.

EHS and Compliance

Our executive team places the highest priority on the health and safety of our staff and third parties at our project sites, as well as the preservation of the environment. Our corporate culture is built around supporting these priorities, as reflected in our well-established practices and policies. By setting and maintaining high standards in the renewable energy field, we are often able to contribute positively to the safety practices and policies of our host landfills, which reflects favorably on us with potential hosts when choosing a counterparty. Our high safety standards include use of wireless gas monitoring safety devices, active monitoring of all field workers, performance of regular EHS audits and the use of technology throughout our safety processes from employee training in compliance with operational processes and procedures to emergency preparedness. By extension, we incorporate our EHS standards into our subcontractor selection qualifications to ensure our commitment to high EHS standards is shared by our subcontractors, which provides further assurances to our host landfills.

Nature of Business

Capture and Conversion Business

We typically secure our Biogas Conversion Projects through a combination of long-term gas rights, manure supply agreements and property lease agreements with biogas site hosts. Our Biogas Conversion Projects provide our landfill and dairy farm partners with a variety of benefits, including (i) a means to monetize biogas from their sites, (ii) regulatory compliance for landfills, (iii) a source of environmentally beneficial waste management practices for dairy farms and (iv) a valuable revenue stream. Once we have negotiated gas rights or manure supply agreements, we then design, develop, build, own and operate facilities that convert the biogas into RNG or use the processed biogas to produce Renewable Power. We sell the RNG produced by the Biogas Conversion Projects through RNG marketing and dispensing agreements and generate associated Environmental Attributes. These Environmental Attributes are then sold to obligated parties as defined under the RFS promulgated by the U.S. federal government and Low Carbon Fuel Standard Programs established by several states. We also sell Renewable Power to public utilities through power purchase agreements.

We believe there are other sources of biogas in the United States, and internationally, that could be utilized for potential future Biogas Conversion Project opportunities. We expect to continue our growth by taking advantage of these opportunities while also continuing to capitalize on additional vertical integration opportunities. Our evaluation and execution of project opportunities will benefit from our ability to leverage our industry experience, relationships with customers and vendors, knowledge about transmission and distribution utility interconnections, and capabilities to design, develop, construct, operate, maintain and service Biogas Conversion Projects and Fueling Stations. We exercise financial discipline in pursuing these projects by targeting project returns that are in line with the relative risk of the specific projects.

Our current Biogas Conversion Projects generate RNG from landfill sites and dairy farms. We view the acquisition of new ~~landfill gas~~LFG, dairy farm, and other biogas waste projects as significant opportunities for us to expand our RNG business, complementing the ongoing conversion of certain of our existing Renewable Power plants to RNG production facilities. We believe our business is scalable and will continue to support growth through development and acquisitions.

We differentiate ourselves from our competitors based on our vertically integrated business model and long history of working with leading vendors, technologies and utilities. Our competitive advantage is further strengthened by our expertise in designing, developing, constructing and operating Biogas Conversion Projects and Fueling Stations.

Dispensing and Monetization Business

We are a leading provider of RNG marketing and dispensing in the alternative vehicle fuels market for heavy and medium-duty trucking fleets throughout the United States. In this sector, we focus on dispensing RNG through Fueling Stations that serve fleets that use natural gas instead of diesel fuel. These Fueling Stations and dispensing services are key for our business because Environmental Attributes are generated through dispensing RNG at these stations for use as vehicle fuel for transportation, and, once generated, the Environmental Attributes can then be monetized.

During ~~2024~~2025, we dispensed 74 million gasoline gallon equivalent ("GGEs") of RNG to the transportation market, generating corresponding Environmental Attributes, utilizing our current network of Fueling Stations across the United States.

Hydrogen Fuel

In the coming years, we believe we will be able to provide hydrogen fuel to vehicle fleets by constructing and servicing hydrogen ~~fueling~~Fueling ~~stations~~Stations as well as providing RNG for hydrogen production.

How We Generate Revenue

Overview. Our revenues are driven principally from the sale of Environmental Attributes that are generated from dispensing RNG as transportation fuel for heavy and medium-duty trucking fleets at Fueling Stations. In addition, we generate revenue from (i) the sale of Renewable Power, (ii) design, development, construction and service of Fueling Stations, and (iii) sales of RNG produced by OPAL and third parties as pipeline quality natural gas.

Environmental Attributes. Currently, our Environmental Attributes revenue stream is primarily comprised of RINs, LCFS credits, ISCC Carbon Credits and RECs. If RNG is dispensed into vehicles as transportation fuel, RINs will be generated under the RFS program. In certain states, there are LCFS programs, which allow a credit to be generated based on a fuel’s carbon intensity score. If RNG is used to produce hydrogen which is consumed in the transportation market in a state where an LCFS program is available, an LCFS credit may be generated as well. Lastly, LFG-to-Renewable Power projects can create Environmental Attributes, in the form of a REC, in certain states and can be bundled with electricity off-take or monetized separately. See "Biogas RNG Market Opportunity".

Power Purchase Agreements. Our Renewable Power projects have associated Power Purchase Agreements (“PPAs”) with creditworthy utility off-takers or municipalities. Nearly all of our Renewable Power off-takers have investment grade credit ratings with either S&P or Moody’s. As discussed above, we also generate RECs from Renewable Power projects through the conversion of biogas to Renewable Power.

Fueling Station Construction and Services. We have significant experience in the engineering, design, construction and operation of Fueling Stations that dispense RNG. We use a combination of custom designed and off-the-shelf equipment to build these stations. We also perform in-house manufacturing ~~and~~of modularized portable CNG compressor packages for smaller dispensing stations, utilizing our patented technology that allows faster and easier station installations. These portable packages can include defueling panels that allow smaller fleet owners to avoid expensive maintenance shop upgrades. In addition, we also generate revenues by providing operations and maintenance services for customer stations; and by helping our customers obtain federal, state and local tax credits, grants and incentives.

Biogas Conversion Projects

Typically, a Biogas Conversion Project includes two phases: (i) biogas collection, and (ii) processing and purifying biogas.

At landfills, biogas collection systems can be configured as vertical wells and horizontal collectors. The most common method is drilling vertical wells into the waste mass and connecting the wellheads to lateral piping that transports the gas to a collection header using a blower or vacuum induction system. Collection system operators “tune” or adjust the wellfield to maximize the volume and quality of biogas collected while maintaining environmental compliance. The existing compliance structure for landfills in the United States benefits us because the EPA requires larger landfills to have collection systems in place to collect and destroy biogas emissions. We turn this compliance cost into a revenue stream for the landfill and are able to leverage existing collection infrastructure in biogas plant design.

A basic biogas processing plant includes: (i) a moisture removal system, (ii) blowers to provide a vacuum to “pull” the gas and pressure to convey the gas and (iii) a flare for destroying unutilized gas. System operators monitor parameters to maximize system efficiency. Using biogas in a Renewable Power facility usually requires some treatment of the landfill gas to remove excess moisture, particulates, and other impurities. The type and extent of treatment depends on site-specific

maximize system efficiency. Using biogas in a Renewable Power facility usually requires some treatment of the LFG to remove excess moisture, particulates, and other impurities. The type and extent of treatment depends on site-specific biogas characteristics and the type of Renewable Power facility. This partially cleaned biogas can be burned on-site to generate Renewable Power which can be immediately used or deployed into the grid. To further upgrade the gas to pipeline quality RNG, the partially treated biogas then goes through a process that separates carbon dioxide from the methane molecules. Further treatment of the biogas is often required to remove residual nitrogen and/or oxygen to meet pipeline specifications.

For dairy waste-to-RNG projects, manure is collected and then scraped or flushed into a reception pit or lagoon, and may be fed into a digester. The biogas equipment then anaerobically digests the manure and produces biogas. There are three different types of anaerobic digesters: (i) covered lagoons (existing lagoons that use large cover to capture methane); (ii) complete mix (large tanks that heat and mix manure), and (iii) plug-flow (long rectangular tanks; unmixed). The biogas is then upgraded to meet pipeline quality specifications.

If a biogas capture and conversion project is not within close proximity to a pipeline, the RNG is transported by road using tube trailers to a gas injection point. This is referred to as a virtual pipeline.

Biogas RNG Market Opportunity

Biogas can be collected and processed to remove impurities for use as RNG (a form of high-Btu fuel) and can be injected into existing natural gas pipelines because it is fully interchangeable with fossil fuel-based natural gas. Partially treated biogas can be used directly in heating applications (as a form of medium-Btu fuel) or in the production of Renewable Power. Our current primary sources of biogas are landfills and dairy farms.

Landfill and livestock-sourced biogas serve as the base to produce RNG, while also reducing GHG emissions. While landfill projects for RNG and Renewable Power have been developed over the past few decades, undeveloped landfills remain a significant source of biogas. Moreover, as technology continues to develop and economic incentives grow, we believe additional sources of biogas will become available for RNG production.

Overview of Landfill Gas Sources

LFG, or landfill gas, is created through the naturally occurring anaerobic decomposition of organic matter. Large landfills have been required by the EPA to capture municipal solid waste landfill emissions for decades due to various regulatory requirements aimed at reducing GHG emissions. The amount of LFG produced from a landfill generally increases as more waste is added to the site. Once a permitted landfill site is completely filled, the landfill will place a cap over the waste. Gas production then follows a generally predictable and modest decline over the next 30 or more years. As a result, LFG has a predictable long-term production profile which, when coupled with the expectation of continued landfill waste growth in the United States for the next 30 years, creates predictable long-term LFG feedstock.

To capitalize on this feedstock opportunity, and to help landfill owners meet growing regulatory requirements for curbing GHG emissions, we enter into long-term gas rights and site lease agreements with landfill owners. The agreement terms are typically at least 20 years. In most cases, the agreements contain renewal provisions. With respect to all of our existing or proposed LFG-to-RNG Biogas Conversion Projects currently in operation or under construction (a total of 14 projects), all but one relates to landfills that are currently open and accepting more waste, which we believe provides a high degree of visibility into the long-term volumes of RNG capable of being generated at each of these projects.

Using proven biogas purification technology, biogas can be processed on-site to remove impurities, and used at around 50% methane to generate Renewable Power. Biogas can be further processed and upgraded to remove carbon dioxide as well as remaining contaminants to increase the methane content and reach pipeline quality specifications, creating RNG. The resulting RNG can be used for all purposes suitable for traditional fossil fuel-based natural gas such as vehicle fuel (e.g., for consumer, industrial and transportation uses, or further converted to renewable hydrogen). RNG can be transported using existing natural gas pipeline infrastructure or through tube trailers. This is an important factor that enables OPAL to design, develop and operate RNG projects to generate value from production of RNG and the associated Environmental Attributes (i.e., RINs and LCFS credits) throughout the United States and exported to international markets.

Overview of Livestock Sources

Livestock is the top agricultural source of GHG worldwide, according to the EPA. Livestock waste, particularly from dairies, produces methane that can be converted to RNG and sold as RNG for consumer, industrial and transportation uses, or further converted to renewable hydrogen. When RNG is produced from livestock waste and used as a vehicle fuel, it effectively reduces emissions from the transportation fleets and also from the livestock facilities that otherwise do not have ~~to collect such methane and is often considered carbon negative. Additionally, revenues generated from dispensing RNG~~

to collect such methane and is often considered carbon negative. Additionally, revenues generated from dispensing RNG produced from livestock farms can be significantly higher than dispensing revenue from RNG produced from landfills due to state-level low-carbon fuel incentives for these projects.

We view dairy farms as a significant opportunity for us to expand our RNG business. Processing biogas from dairy farms requires similar expertise and capabilities as processing biogas from landfills.

The presence of our digester benefits dairy farmers in a number of ways, creating a mutually beneficial relationship. We assist in managing the waste for the dairy farmer, which they would otherwise have to manage. Additionally, processing this waste in a digester is environmentally friendly by reducing GHG emissions. Finally, a byproduct of the production process can be returned to farmers for use as bedding, alleviating the need to purchase other materials for bedding for the cows and/or adding a revenue stream for the dairy farmer when sold to third parties.

Highly Fragmented Market

The LFG market is heavily fragmented, which we believe represents an opportunity for companies like us to find project opportunities. The top players in the industry account for the majority of installed LFG capacity. This market dynamic creates the opportunity for consolidation by well capitalized, experienced market participants such as OPAL.

While LFG has accounted for most of the growth in Biogas Conversion Projects to date, we believe additional economically viable LFG project opportunities exist. According to the EPA LMOP project database, as of July 2023, there were 532 LFG projects in operation in the United States, including 359 operating LFG-to-electricity projects that may be converted to produce RNG as well as 470 additional candidate landfills. Based on EPA data, these 470 candidate landfills have the potential to collect a combined 343 million standard cubic feet of LFG per day. Based on our industry experience, technical knowledge and analysis we believe many of these sites are potentially economically viable for RNG project acquisitions.

Well-Established Regulatory Framework

RINs are credits used by Obligated Parties for regulatory compliance as part of the RFS program. The RFS program is a federal law introduced in 2005 and updated in 2007 to incorporate renewable content into various transportation fuels. Through the RFS program, RINs can be sold to counterparties in order for them to meet their renewable standard requirements. RNG from landfills and livestock waste, among other sources, qualifies as a cellulosic biofuel with a 60% GHG reduction requirement (“D3”) RIN, which is currently the highest priced RIN and commands a premium compared to non-cellulosic renewable fuels such as ethanol and renewable diesel.

We generate RINs when RNG is dispensed into vehicles as transportation fuel, and the RINs can then be sold to, and traded with, market participants who can either retire them or trade them again. By using the RINs, Obligated Parties retire the RINs for compliance purposes. Market participants in the RIN program typically include Obligated Parties and registered RIN market participants. Participants include both domestic and foreign companies.

LCFS programs are state-level market-based programs designed to decrease CI and GHG emissions from the transportation sector. Currently, California and Oregon have established LCFS programs. Additionally, multiple jurisdictions are considering implementation of LCFS programs; for example Canada has proposed programs and Washington state’s program began in 2023.

LCFS programs are attractive because LCFS credits can be additive to RINs. In California, the most established program, the LCFS program is administered by CARB, which sets annual CI standards. Fuel producers in the transportation fuel pool that have lower CI scores than the target established by the California Air Resources Board generate LCFS credits, and those with higher CI scores than the annual standard will generate deficits. A fuel producer with deficits must have enough LCFS credits through either generation or acquisitions to be in annual compliance with the annual standard. We are poised to take advantage of these LCFS programs because RNG from dairies has very low or negative CI, and therefore generates valuable credits in states with LCFS programs.

Currently, it is estimated that RNG production in the United States can only cover about 1.5% of the U.S. heavy- and medium-duty vehicles fuel market. RNG production is projected to increase by 2027, bringing the RNG industry share to as much as 2.5%. Although it is likely that utilities and other consumers will compete with the vehicle fuel market to acquire such RNG, we believe there is adequate potential to continue placing RNG volumes into the transportation market. The legislated D3 RIN requirements are many multiples of current industry production. The EPA sets an RVO each year generally in excess of what the industry is expected to produce but well below the statutory requirement. The EPA has

sharply increased the required volume of the D3 RINs in recent years, with the current D3 RIN RVO level encouraging growth in the industry.

Economic Benefits Incentivize Switching to RNG

RNG vehicles, especially heavy- and medium-duty commercial vehicles, not only have a lower cost of ownership than similar vehicles running on diesel, they also have a lower cost of ownership than their renewable energy peers, especially hydrogen and battery electric vehicles, assuming expected D3 RINs and LCFS pricing. This comparative advantage creates significant economic incentives for heavy and medium-duty commercial vehicle owners to favor RNG.

Our Projects

As of December 31, ~~2024~~2025, we owned and operated 2627 projects, 1112 of which are RNG projects and 15 of which are Renewable Power projects. As of that date, our RNG projects in operation had a design capacity of 89.81 million MMBtus per year and our Renewable Power projects in operation had a nameplate capacity of 105.8 MW per hour. In addition to these projects in operation, we are actively pursuing expansion of our RNG-generating capacity and, accordingly, have a portfolio of RNG projects in construction as well as a portfolio of projects in development, with six of our current Renewable Power projects being considered candidates for conversion to RNG projects in the foreseeable future.

(1) Nameplate capacity is the manufacturer’s expected capacity at ISO conditions for each facility and may not reflect actual production from the projects, which depends on many variables including, but not limited to, (i) quantity and quality of the biogas, (ii) operational up-time of the facility and (iii) actual productivity of the facility.

(2) We have determined that some of our Renewable Power projects are currently RNG conversion candidates. The Company identifies suitable RNG conversion candidates based on highest return of capital which is driven by certain factors including, but not limited to (i) the quantity and quality of LFG, (ii) the proximity to pipeline interconnect and (iii) the ability to enter into contracts, including site leases and gas rights agreements, with host sites. The Company may change its decision to convert a Renewable Power Project into an RNG project in the future. The Company believes

the ability to enter into contracts, including site leases and gas rights agreements, with host sites. The Company may change its decision to convert a Renewable Power Project into an RNG project in the future. The Company believes disclosing Renewable Power conversion candidates provides visibility into the effect of those conversions on the existing Renewable Power portfolio.

(3) Although the RNG conversion is completed, it is currently contemplated that the Arbor Hills Renewable Power plant will continue limited operations on a stand-by, emergency basis through March of 2031.

(4) Construction of the Fall River project has been delayed due to permitting issues.

Competition

Our primary competition is from other companies or solutions for access to biogas from waste. Evolving consumer preferences, regulatory conditions, ongoing waste industry trends, and project economics have a strong effect on the competitive landscape and our relative ability to continue to generate revenues and cash flows. We believe based on (i) our status as one of the largest operators of LFG-to-RNG projects, (ii) our over 20-year track record of operating and developing projects, (iii) our vertically integrated business platform, (iv) our deep relationships with some of the largest landfill owners and (v) our relationships with dairy producers in the country, we are well-positioned to continue to operate and grow our portfolio and respond to competitive pressures. We have demonstrated a track record of strategic flexibility over our greater than 20-year history which has allowed us to pivot towards projects and markets that we believe deliver optimal returns and ~~shareholder~~stockholder value in response to changes in market, regulatory and competitive pressures.

The biogas market is highly fragmented. We believe both our size compared to other LFG companies and our capital structure puts us in a strong position to compete for new project development opportunities or acquisitions of existing projects. However, competition for such opportunities, including the prices being offered for gas supply, will impact the expected profitability of projects, and may make projects unsuitable to pursue. Likewise, prices being offered by our competitors for fuel supply may increase the royalty rates that we pay under our fuel supply agreements when such agreements expire and need to be renewed or when expansion opportunities present themselves at the landfills where our projects currently operate. It is also possible that more landfill owners and dairy farm owners may seek to install their own RNG production facilities on their sites, which would reduce the number of opportunities for us to develop new projects. Our overall size, reputation, access to capital, experience and decades of proven execution on LFG project development and operation position us to compete strongly amongst our industry peers.

Governmental Regulation

General

Each of our projects is subject to federal, state and local air quality, solid waste, and water quality regulations and other permitting requirements. Specific construction and operating permit requirements may differ among states. Specific permits we frequently must obtain when developing our projects include: air permits, nonhazardous waste management permits, pollutant discharge elimination permits, zoning and beneficial use permits. Our existing projects must also maintain compliance with relevant federal, state and local EHS requirements.

Our RNG projects are subject to federal RFS program regulations, including the Energy Policy Act of 2005 (the “EPACT 2005”) and EISA. The EPA administers the RFS program with volume requirements for several categories of renewable fuels. The EPA’s RFS regulations establish rules for fuel supplied and administer the RIN system for compliance, trading credits and rules for waivers. The EPA calculates a blending standard for each year based on estimates of gasoline usage from the Department of Energy’s Energy Information Agency. Separate quotas and blending requirements are determined for cellulosic biofuels, biomass-based diesel, advanced biofuels and total renewable fuel. Further, we are required to register each RNG project with the EPA and relevant state regulatory agencies. We qualify our RINs through a voluntary Quality Assurance Plan, which typically takes from three to five months from first injection of RNG into the commercial pipeline system. Further, we typically make a large investment in the project prior to receiving the regulatory approval and RIN qualification. In addition to registering each RNG project, we are subject to quarterly audits under the Quality Assurance Plan of our projects to validate our qualification.

Our RNG projects are also subject to state renewable fuel standard regulations. By way of example, the LCFS program in California required producers of petroleum-based fuels to reduce the CI of their products by at least 10% by 2020 and requires a reduction of at least 20% by 2030 from a 2010 baseline. Petroleum importers, refiners and wholesalers can either develop their own low-carbon fuel products or buy California LCFS credits from other companies that develop and sell low-carbon alternative fuels, such as biofuels, electricity, natural gas or hydrogen. We are subject to a qualification process similar to that for RINs, including verification of CI levels and other requirements that currently exist for LCFS credits in California.

similar to that for RINs, including verification of CI levels and other requirements that currently exists for LCFS credits in California.

The EPA under the Clean Air Act (the “CAA”) regulates emissions of pollutants to protect the environment and public health. The CAA contains provisions for New Source Review (the “NSR”) permits and Title V permits. New Biogas Conversion Projects may be required to obtain construction permits under the NSR program. The combustion of biogas results in emissions of carbon monoxide, oxides of nitrogen, sulfur dioxide, volatile organic compounds and particulate matter. The CAA and state and local laws and regulations impose significant monitoring, testing, recordkeeping and reporting requirements for these emissions. Requirements vary for control of these emissions, depending on local air quality. Applicability of the NSR permitting requirements will depend on the level of emissions resulting from the technology used and the project’s location. Many Biogas Conversion Projects must obtain operating permits that satisfy Title V of the 1990 CAA Amendments. The operating permit describes the emission limits and operating conditions that a facility must satisfy and specifies the reporting requirements that a facility must meet to show compliance with all applicable air pollution regulations. A Title V operating permit must be renewed every five years. Even when a biogas project does not require a Title V permit, the project may be subject to other federal, state and/or local air quality regulations and permits.

In addition, our operations and the operations of the landfills at which we operate may be subject to New Source Performance Standards and emissions guidelines, pursuant to the CAA, applicable to municipal solid waste landfills and to oil and gas facilities. Among other things, these regulations are designed to address the emission of methane, a potent GHG, into the atmosphere.

Before an RNG project can be developed, all the Resource Conservation and Recovery (the “RCRA”) Subtitle D requirements (requirements for nonhazardous solid waste management) must be satisfied. In particular, methane is explosive in certain concentrations and poses a hazard if it migrates beyond the project boundary. Biogas collection systems must meet RCRA Subtitle D standards for gas control. RNG projects may be subject to other federal, state and local regulations that impose requirements for nonhazardous solid waste management.

Certain Biogas Conversion Projects may be subject to federal requirements to prepare for and respond to spills or releases from tanks and other equipment located at these projects and provide training to employees on operation, maintenance and discharge prevention procedures and the applicable pollution control laws. At such projects, we may be required to develop spill prevention, control and countermeasure plans to memorialize our preparation and response plans and to update them on a regular basis.

Our operations may result in liability for hazardous substances or other materials placed into soil or groundwater. Pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980 or other federal, state or local laws governing the investigation and cleanup of sites contaminated with hazardous substances, we may be required to investigate and/or remediate soil and groundwater contamination at our projects, contiguous and adjacent properties and other properties owned and/or operated by third parties.

Additionally, Biogas Conversion Projects may need to obtain National Pollutant Discharge Elimination System permits if wastewater is discharged directly to a receiving water body. If wastewater is discharged to a local sewer system, Biogas Conversion Projects may need to obtain an industrial wastewater permit from a local regulatory authority for discharges to a Publicly Owned Treatment Works. The authority to issue these permits may be delegated to state or local governments by the EPA. The permits, which typically last five years, limit the quantity and concentration of pollutants that may be discharged. Permits may require wastewater treatment or impose other operating conditions to ensure compliance with the limits. In addition, the Clean Water Act and implementing state laws and regulations require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities.

FERC

FERC regulates the sale of electricity at wholesale and the transmission of electricity in interstate commerce pursuant to its regulatory authority under the Federal Power Act. FERC also regulates certain natural gas transportation and storage facilities and services, and regulates the rates and terms of service for natural gas transportation in interstate commerce under the Natural Gas Act and the Natural Gas Policy Act.

With respect to electricity transmission and sales, FERC’s jurisdiction includes, among other things, authority over the rates, charges and other terms for the sale of electricity at wholesale by public utilities (entities that own or operate projects subject to FERC jurisdiction) and for transmission services. With respect to its regulation of the transmission of electricity, FERC requires transmission providers to provide open access transmission services, which supports the development of competitive markets by assuring nondiscriminatory access to the transmission grid. FERC has also encouraged the formation of RTOs to allow greater access to transmission services and certain competitive wholesale markets administered by ISOs and RTOs.

competitive markets by assuring nondiscriminatory access to the transmission grid. FERC has also encouraged the formation of RTOs to allow greater access to transmission services and certain competitive wholesale markets administered by ISOs and RTOs.

In 2005, the U.S. federal government enacted the EPACT 2005 conferring new authority for FERC to act to limit wholesale market power if required and strengthening FERC’s civil penalty authority (including the power to assess fines of up to $1.3 million per day per violation, as adjusted due to inflation), and adding certain disclosure requirements. EPACT 2005 also directed FERC to develop regulations to promote the development of transmission infrastructure, which provides incentives for transmitting utilities to serve renewable energy projects and expanded and extended the availability of U.S. federal tax credits to a variety of renewable energy technologies, including wind power. EPACT 2005’s market conduct, penalty and enforcement provisions also apply to fraud and certain other misconduct in the natural gas sector.

Qualifying Facilities

The Public Utility Regulatory Policies Act established a class of generating facilities that would receive special rate and regulatory treatment ("QFs"). There are two categories of QFs: qualifying small power production facilities and qualifying cogeneration facilities. A small power production facility is a generating facility of 80 MW or less whose primary energy source is hydro, wind, solar, biomass, waste, or geothermal. A cogeneration facility is a generating facility that produces electricity and another form of useful thermal energy (such as heat or steam) in a way that is more efficient than the separate production of both forms of energy. QFs are generally subject to reduced regulatory requirements. Small power production facilities up to 20 MW and “eligible” facilities as defined by section 3(17)(E) of the Federal Power Act are exempt from rate regulation under Sections 205 and 206 of the Federal Power Act.

In addition, PUHCA provides FERC and state regulatory commissions with access to the books and records of holding companies and other companies in holding company systems. It also provides for the review of certain costs. Companies that are holding companies under PUHCA solely with respect to one or more exempt wholesale generators, certain QFs or foreign utility companies are exempt from these PUHCA books and records requirements.

State Utility Regulation

While federal law provides the utility regulatory framework for our sales of electricity at wholesale in interstate commerce, there are also important areas in which state regulatory control over traditional public utilities that fall under state jurisdiction may have an effect on our projects. For example, the regulated electricity utility buyers of electricity from our projects are generally required to seek state public utility commission approval for the pass through in retail rates of costs associated with PPAs entered into with a wholesale seller. Certain states, such as New York, regulate the acquisition, divestiture, and transfer of some wholesale power projects and financing activities by the owners of such projects. California, which is one of our markets, requires compliance with certain operations and maintenance reporting requirements for wholesale generators. In addition, states and other local agencies require a variety of environmental and other permits.

State law governs whether an independent generator or power marketer can sell retail electricity in that state, and whether gas can be sold by an entity other than a traditional, state-franchised gas utility. Some states, such as Florida, prohibit most sales of retail electricity except by the state’s franchised utilities. In other states, such as New Jersey and Pennsylvania, an independent generator may sometimes sell retail electricity power to a co-located or adjacent business customer, and a gas supplier can sometimes make on-premises or adjacent-premises gas deliveries to a single plant or customer. Some states, such as Massachusetts and New York, permit retail power and gas marketers to use the facilities of the state’s franchised utilities to sell power and/or gas to retail customers as competitors of the utilities.

RNG Production and Sale

Our projects typically convert biogas to RNG for sale as a fuel product. FERC regulates the natural gas pipelines that transport gas in interstate commerce, and specifies or approves a gas pipeline’s tariff that sets the rates, terms and conditions, gas quality, and other requirements applicable to transportation of natural gas on the pipelines, including shipping RNG. Our sites are not permitted, and may not be physically able, to deliver RNG to a FERC-regulated pipeline unless the pipeline’s receipt of the gas is consistent with the standards adopted in the pipeline’s FERC tariff. State regulators determine whether RNG may be purchased by the state’s local gas utilities, and whether a site operator may directly sell gas to a retail, or direct end-use, customer. Purely local gas sales not utilizing FERC-regulated or certificated facilities are typically not subject to FERC gas regulation. The local distribution of gas to end-use customers by a state-regulated gas utility is also typically outside the scope of FERC’s gas regulatory jurisdiction. The opening and operation of a landfill or dairy farm that is expected to produce gas does not ordinarily require a FERC certificate or the acceptance by FERC of a gas tariff.

a landfill or dairy farm that is expected to produce gas does not ordinarily require a FERC certificate or the acceptance by FERC of a gas tariff.

Future Regulations

The regulations that are applicable to our projects vary according to the type of energy being produced and the jurisdiction of the facility. As part of our growth strategy, we are looking to grow by pursuing development and acquisition opportunities. Such opportunities may exist in jurisdictions where we have no current operations and, as such, we may become exposed to different regulations for which we have no experience. Some states periodically revisit their regulation of electricity and gas sales. Other states, such as South Carolina and Florida, have adhered to traditional exclusive franchise practices, and in these and other states most electricity and gas customers may receive service only from a utility that holds an exclusive geographic franchise to provide service at that customer’s location. In some states that have experienced energy price hikes or market volatility, such as New York, Texas and California, investments in expanding facilities or buying or building additional facilities may be subject to changing regulatory requirements that may encourage competitive market entry.

The Inflation Reduction Act (the “IRA”) was signed into law on August 16, 2022. The bill invests nearly $369 billion in energy and climate policies. The provisions of the IRA are intended to, among other things, incentivize domestic clean energy investment, manufacturing, and deployment. The IRA incentivizes the deployment of clean energy technologies by extending and expanding federal incentives such as ITCs and ~~the~~ Production Tax ~~Credit~~Credits (~~the~~ "~~PTC~~PTCs"). We view the enactment of the IRA as favorable for the overall business climate for the renewable energy industry. However, there is uncertainty related to the applicability of the IRA to our current and planned projects and the scope of the IRA and its interpretations under the new U.S. administration or if government agencies’ authority to interpret federal law is restricted as a result of the Supreme Court’s review of the Chevron doctrine under which federal government agencies have been awarded broad authority to interpret broad or ambiguous legislation. We may also continue to experience a delay in our sales cycles and new award activity as our customers consider the applicability of the IRA and as financing projects may take longer as result of this uncertainty. The IRA may increase the competition in our industry and as such increase the demand and cost for labor, equipment and commodities needed for our projects. 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.

Our business is affected by numerous laws and regulations on the international, federal, state and local levels, including energy, environmental, conservation, tax and other laws and regulations relating to our industry. Failure to comply with any laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of injunctive relief or both. Moreover, changes in any of these laws and regulations could have a material adverse effect on our business. In view of the many uncertainties with respect to current and future laws and regulations, including their applicability to us, we cannot predict the overall effect of such laws and regulations on our future operations.

We believe our operations comply in all material ~~respect~~respects with applicable laws and regulations and that the existence and enforcement of such laws and regulations have no more restrictive an effect on our operations than on other similar companies in our industry. We do not anticipate any material capital expenditures to comply with international, federal and state environmental requirements.

Facilities

Our corporate headquarters are located in White Plains, New York, where we occupy approximately 13,600 square feet of shared office space with Fortistar pursuant to an Administrative Services Agreement. We believe this office space is adequate for our needs for the immediate future and that, should it be necessary, we can lease additional space to accommodate any future growth.

Our services office and maintenance facility is located in Oronoco, Minnesota, where we own and occupy a 20,000 square foot building of combined office space, maintenance shop and loading dock located on 3.25 acres. The building was acquired in September 2018 and is adequate for our needs for the immediate future. Should it be necessary, we believe we can expand the building to accommodate future growth.

Our construction office and maintenance facility is located in Rancho Cucamonga, California, where we occupy approximately 29,935 square feet of combined office space, maintenance shop and loading dock. In March 2022, we entered into an amendment to the lease which extended the lease term to January 2026. We believe the space that we currently lease is adequate for our needs for the immediate future but we may seek additional space to accommodate future growth, which we believe will be available to us on satisfactory terms.

ITEM 1A. RISK FACTORS

Item 1A. Risk Factors

There are many factors that affect our business and results of operations, some of which are beyond our control. The following is a description of some important factors that may cause the actual results of operations in future periods to differ materially from those currently expected or desired.

Risk Factors Summary

Risks Related to Our Business

•We are dependent on contractual arrangements with, and the cooperation of, owners and operators of biogas project sites where our Biogas Conversion Projects are located for the underlying biogas rights granted to us in connection with our Biogas Conversion Projects and for access to and operations on the biogas project sites where we utilize those underlying biogas rights.

•The owners and operators of biogas project sites generally make no warranties to us as to the quality or quantity of gas produced.

•Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in developing, constructing, bringing online and operating our Biogas Conversion Projects and Fueling Stations, which could damage our reputation, adversely affect our partner relationships or adversely affect our growth.

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

•Our Biogas Conversion Projects face operational challenges, including among other things the breakdown or failure of equipment or processes or performance below expected levels of output or efficiency due to wear and tear of our equipment, latent defects, design or operator errors, force majeure events, or lack of transmission capacity or other problems with third party interconnection and transmission facilities.

•A reduction in the prices we can obtain for the Environmental Attributes generated from RNG, which include RINs, ISCC Carbon Credits, LCFS credits, and other incentives, could have a material adverse effect on our business prospects, financial condition and results of operations.

•Volatility in the price of oil, gasoline, diesel, natural gas, RNG, or Environmental Attribute prices could adversely affect our business.

•We face significant upward pricing pressure in the market with respect to our securing the biogas rights necessary for proposed new Biogas Conversion Projects and our conversion of existing Renewable Power rights to RNG rights on existing Biogas Conversion Projects that we plan to convert.

•Our ability to acquire, convert, develop and operate Biogas Conversion Projects, as well as expand production at current Biogas Conversion Projects, is subject to many risks.

•Our success is dependent on the willingness of commercial fleets and other counterparties to adopt, and continue use of RNG, which may not occur in a timely manner, at expected levels or at all. Our vehicle fleet counterparties may choose to invest in renewable vehicle fuels other than RNG.

•Our failure to dispense a specified quality or quantity of RNG could have a material adverse effect on our financial condition and results of operations, by subjecting us to, among other things, possible penalties or terminations under the various contractual arrangements under which we operate, including pursuant to a purchase and sale agreement related to the sale of our Environmental Attributes.

•Our increasing reliance on information technology and other systems subjects us to risks associated with cybersecurity. Cybersecurity incidents or our failure to maintain the security and integrity of Company, employee,

associate, customer or third-party data could have a disruptive effect on our business and adversely affect our reputation and financial performance.

•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.

Risks Related to Regulations or Governmental Actions

•Our operations are subject to numerous stringent EHS laws and regulations that may expose us to significant costs and liabilities. From time to time, we have been issued notices of violations from government entities that our operations have failed to comply with such laws and regulations. Failure to comply with such 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.

•Existing and 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.

•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.

Risks Related to Our Indebtedness

•Our level of indebtedness and preferred stock redemption obligations 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. We may be unable to obtain additional financing to fund our operations or growth.

Risks Related to Ownership of Our Class A Common Stock

•We are a controlled company, and thus not subject to all of the corporate governance rules of Nasdaq. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

Risks Related to Our Business

We are dependent on contractual arrangements with, and the cooperation of, owners and operators of biogas project sites where our Biogas Conversion Projects are located for the underlying biogas rights granted to us in connection with our Biogas Conversion Projects and for access to and operations on the biogas project sites where we utilize those underlying biogas rights.

We do not own any of the biogas project sites from which our Biogas Conversion Projects collect biogas, and therefore we depend on contractual relationships with, and the cooperation of, site owners and operators for our operations. The invalidity of, or any default or termination under, any of our gas rights agreements, leases, easements, licenses and rights-of-way may interfere with our rights to the underlying biogas and our ability to use and operate all or a portion of our Biogas Conversion Projects facilities, which may have an adverse impact on our business, financial condition and results of operations.

We obtain rights to utilize the biogas and the biogas project sites on which our projects operate under contractual arrangements, with the associated biogas rights generally being for fixed terms of 20 years or more, with certain additional renewal options. See “Business — Our Projects.” Because the rights we hold in connection with our projects typically include the right to produce electricity generated from Renewable Power, or RNG, but not both, when we pursue conversion of a project from the production of Renewable Power to the production of RNG, which has been part of our strategy over recent periods, we must secure the associated biogas rights for the production of RNG. While we have generally been successful in renewing biogas rights and in securing additional rights necessary in connection with conversion from production of Renewable Power to RNG, we cannot guarantee that this success will continue 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 site owners and operators from whose biogas project sites our Biogas Conversion Projects obtain biogas or for whom we operate biogas facilities, may have a material adverse effect on our business operations, financial condition and operational results.

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 site owners and operators from whose biogas project sites our Biogas Conversion Projects obtain biogas or for whom we operate biogas facilities, may have a material adverse effect on our business operations, financial condition and operational results.

In addition, the ownership interests in the land subject to the licenses, easements, leases and rights-of-way necessary for the operation of our business may be subject to mortgages securing loans or other liens (such as tax liens) and other easements, lease rights and rights-of-way of third parties (such as leases of mineral rights). As a result, certain of our rights under these licenses, easements, leases or rights-of-way may be subject, and subordinate, to the rights of those third parties in certain instances. 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 Biogas Conversion 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.

The owners and operators of biogas project sites generally make no warranties to us as to the quality or quantity of gas produced.

The Biogas Conversion Project site owners and operators generally do not make any representation or warranty to us as to the quality or quantity of biogas produced at their sites. Accordingly, we may be affected by operational issues encountered by biogas conversion project site owners and operators in operating their facilities that may affect the quantity and quality of biogas, including, among other things: (i) their ability to perform in accordance with their commitments to third parties (other than us) under agreements and permits; (ii) transportation of source materials, (iii) herd health and labor issues at the dairy farms generating the manure to be processed at our digester facilities; (iv) gas collection issues at landfill projects such as broken pipes, ground water accumulation, inadequate landcover and labor issues, and (v) the particular character and mix of trash received. We cannot guarantee that our production will be free from operational risks, nor can we guarantee the production of a sufficient quantity and quality of biogas from the owners and operators of biogas conversion project sites.

From time to time, we face disputes or disagreements with owners and operators of biogas project sites which could materially impact our ability to continue to develop and/or operate an existing Biogas Conversion Project on its current basis, or at all, and could materially delay or eliminate our ability to identify and successfully secure the rights to construct and operate other future Biogas Conversion Projects.

The success of our business depends, in part, on maintaining good relationships with biogas conversion project site owners and operators. As a result, our business may be adversely affected if we are unable to maintain these relationships.

We may disagree with owners and operators about a number of concerns, including, without limitation, the operations of the biogas project sites, easement and access rights, the renewal of gas and manure rights on favorable terms, and temporary shutdowns for routine maintenance or equipment upgrades. Biogas conversion project site owners and operators may make unilateral decisions beneficial to them to address business concerns without consulting with us, including in circumstances where they have a contractual obligation to do so. Such decisions made by the biogas conversion project site owners and operators could impact our ability to produce RNG or Renewable Power and generate the associated Environmental Attributes.

In addition, the financial condition of the biogas conversion project sites may be affected by conditions and events that are beyond our control. Significant deterioration in the financial condition of any biogas conversion project waste site could cause the biogas conversion project site owners and operators to shut down or reduce their landfill or livestock waste operations. Any such closure or reduction of operations at a waste site could impact our ability to produce RNG or Renewable Power, and generate the associated Environmental Attributes, and we may not have an opportunity to propose a solution to protect our infrastructure in any existing Biogas Conversion Project.

If we are unable to maintain good relationships with these site owners and operators, or if they take any actions that disrupt or halt production of RNG or Renewable Power, our business, financial condition and results of operations could be materially and adversely affected.

For the U.S. transportation fuel market, we are dependent on the production of vehicles and engines capable of running on natural gas and we have no control over these vehicle and engine manufacturers. We are also dependent on the willingness of owners of truck fleets to adopt natural gas-powered vehicles and to contract with us for the provision of compressed natural gas to these fleets.

We are dependent on vehicle and engine manufacturers to succeed in our target RNG fuel dispensing markets, and we have no influence or control over their activities. These manufacturers may decide not to expand or maintain, or may decide to discontinue or curtail, their product lines for a variety of reasons, including, without limitation, as a result of the adoption of governmental policies or programs such as the rules adopted by the California Air Resources Board on June 25, 2020 requiring the sale of zero-emission heavy-duty trucks and Executive Order N-79-20 issued by the Governor of the State of California in September 2020. The supply of engines or vehicle product lines by these vehicle and engine manufacturers may also be disrupted due to delays, restrictions or other business impacts related to supply chain disruptions, crises or other developments. The limited production of engines and vehicles that run on natural gas increases their cost and limits availability, which restricts large-scale adoption, and may reduce resale value. These factors may also contribute to operator reluctance to convert their vehicles to be compatible with natural gas fuel.

Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in developing, constructing, bringing online and operating our Biogas Conversion Projects and Fueling Stations, which could damage our reputation, adversely affect our partner relationships or adversely affect our growth.

Our success depends on our ability to design, develop, construct, maintain and operate Biogas Conversion Projects and Fueling Stations 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 Biogas Conversion Projects and Fueling Stations, we rely on products meeting our design specifications, components manufactured and supplied by third parties and services performed by our subcontractors. We also rely on subcontractors to perform some of the construction and installation work related to our Biogas Conversion Projects and Fueling Stations, and we sometimes need to engage subcontractors with whom we have no prior experience in connection with these matters.

If our subcontractors are unable to provide services that meet or exceed our counterparties’ 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 our suppliers and service providers, we may incur liability to our counterparties 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 our ability to timely bring a project online, the quality and performance of our Biogas Conversion Projects and Fueling Stations, and may require considerable expense to find replacement products and to maintain and repair these facilities. These circumstances could cause us to experience interruption in our production and distribution of RNG and Renewable Power or the generation of related Environmental Attributes or RNG dispensing at Fueling Stations, potentially harming our brand, reputation and growth prospects.

We rely on interconnection, transmission and pipeline facilities that we do not own or control and that are subject to constraints within a number of our regions. If these facilities fail to provide us with adequate capacity or have unplanned disruptions, we may be restricted in our ability to deliver Renewable Power and RNG to our counterparties 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 and fuel we generate at our Biogas Conversion Projects to our counterparties. Some of our electric generating Biogas Conversion 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 or the Public Utility Commission in the jurisdictions in question. 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 sales of Renewable Power.

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 or increased operating expenses. Such failures or delays could limit the amount of Renewable Power our operating facilities deliver or delay the completion of our construction projects, which may also result in adverse consequences under our power purchase agreements and LFG rights agreements. Further, such failures, delays or increased costs could have a material adverse effect on our business, financial condition and results of operations.

Our RNG production projects are similarly interconnected with gas distribution and interstate pipeline systems that are necessary to deliver RNG. A failure or delay in the operation or development of these distribution or pipeline facilities could result in a loss of revenues or breach of contract because such a failure or delay could limit the amount of RNG that we are able to produce or delay the completion of our construction projects. In addition, certain of our RNG transportation capacity may be curtailed without compensation due to distribution and pipeline limitations, reducing our revenues and impairing our ability to capitalize fully on a particular project’s potential. Such a failure or curtailment at levels above our expectations could impact our ability to satisfy our contractual obligations and adversely affect our business. Additionally, we experience work interruptions from time to time due to federally required maintenance shutdowns of distribution and pipeline facilities.

We may acquire or develop RNG projects that require their own pipeline interconnections to available interstate pipeline and distribution networks. In some cases, these pipeline and distribution networks to which such projects are connected may cover significant distances. A failure in the construction or operation of these pipeline and distribution networks that causes the RNG project to be out of service, or subject to reduced service, could result in lost revenues because it could limit our production of RNG and the associated Environmental Attributes that we are able to generate.

We rely on third-party utility companies to provide our Biogas Conversion Projects with adequate utility supplies, including sewer, water, gas and electricity, in order to operate our Biogas Conversion Project facilities. Any failure on the part of such companies to adequately supply our facilities with such utilities, including any prolonged period of loss of electricity, may have an adverse effect on our business and results of operations.

We are dependent on third-party utility companies to provide sufficient utilities including sewer, water, gas and electricity, to sustain our operations and operate our Biogas Conversion Projects. Any major or sustained disruptions in the supply of utilities may disrupt our operations or damage our production facilities or inventories and could adversely affect our business, financial condition and results of operations. In addition, we consume a significant amount of electricity in connection with our Biogas Conversion Projects and any increases in costs or reduced availability of such utilities could have a negative impact on our business, financial condition and results of operations.

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

We are subject to risks and costs, including potential negative publicity, associated with lawsuits, in particular with respect to environmental claims and lawsuits or claims contesting the construction or operation of our Biogas Conversion Projects and Fueling Station projects. The result of and costs associated with defending any such lawsuit or claim, 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 our business related to Biogas Conversion Projects or Fueling Stations. For example, individuals and interest groups may sue to challenge the issuance of a permit for a Biogas Conversion Project or a Fueling Station project, or seek to enjoin construction or operation of that facility. We may also become subject to claims from individuals who live in the proximity of our Biogas Conversion Projects and Fueling Stations 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 Biogas Conversion Projects and Fueling Stations.

Any such legal proceedings or disputes could delay our ability to complete construction of a Biogas Conversion Project or Fueling Station in a timely manner or at all, or materially increase the costs associated with commencing or continuing commercial operations of such projects. Settlement of claims and unfavorable outcomes or developments relating to such 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 currently own, and in the future may acquire, certain assets in which we have limited control over management decisions, including through joint ventures, and our interests in such assets may be subject to transfer or other related restrictions.

We own, and in the future may acquire, certain Biogas Conversion Projects and Fueling Stations through joint ventures. In the future, we may invest in other projects with a joint venture or strategic 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 Biogas Conversion Project or Fueling Station, 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 Biogas Conversion Project or Fueling Station, 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 with our joint venture partners, where our joint venture partners’ business interests are inconsistent with our and our stockholders’ interests. Further, disagreements or disputes with our joint venture partners could result in litigation, resulting in increase of expenses incurred and potentially limit the time and effort our officers and directors are able to devote to remaining aspects of 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, rights of first offer or other similar rights in the event of a proposed sale or transfer of our interests in such assets. In addition, we may have, and correspondingly our joint venture partners may have, rights to force the sale of the joint venture upon the occurrence of certain defaults or breaches by the other partner or other circumstances, and there may be circumstances in which our joint venture partner can replace our affiliated entities that provide operation and maintenance and asset management services if they default in the performance of their obligations to the joint venture. These restrictions and other provisions may limit the price or interest level for our interests in such assets, in the event we want to sell such interests.

These restrictions and other provisions may limit the price or interest level for our interests in such assets, in the event we want to sell such interests.

Our gas rights agreements, power purchase agreements, fuel-supply agreements, interconnection agreements, RNG dispensing agreements and other agreements, including contracts with owners and operators of biogas conversion project sites, often contain complex provisions, including those relating to price adjustments, calculations and other terms based on gas price indices and other metrics, as well as other terms and provisions, the interpretation of which could result in disputes with counterparties that could materially affect our results of operations and customer or other business relationships.

Certain of our gas rights agreements, power purchase agreements, fuel supply agreements, interconnection agreements, RNG dispensing agreements and other agreements, including contracts with owners and operators of biogas conversion project sites, require us to make payments or adjust prices to counterparties based on past or current changes in natural gas price indices, project productivity or other metrics and involve complex calculations.

Moreover, the underlying indices governing payments under such 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 such agreements. Any such disputes could adversely affect Biogas Conversion Project revenues, including revenue from associated Environmental Attributes, profit margins, customer or supplier relationships, or lead to costly litigation, the outcome of which we would be unable to predict.

A reduction in the prices we can obtain for the Environmental Attributes generated from RNG, which include RINs, ISCC Carbon Credits, LCFS credits, and other incentives, could have a material adverse effect on our business prospects, financial condition and results of operations.

A significant portion of our revenues comes from the sale of Environmental Attributes, which exist because of legal and governmental regulatory requirements. A change in law or in governmental policies concerning renewable fuels, landfill or animal waste site biogas or the sale of Environmental Attributes could be expected to affect the market for, and the pricing of, the Environmental Attributes that we can generate through production at our Biogas Conversion Projects. A reduction in the prices we receive for Environmental Attributes, or a reduction in demand for them, whether through market forces generally, through the actions of market participants generally, or through the consolidation or elimination of participants competing in the market for the purchase and retirement of Environmental Attributes, could have a material adverse effect on our results of operations. The current regulatory regime also creates uncertainty related to the future market for such Environmental Attributes and this could have an adverse effect on the earnings we generate from such attributes.

~~The~~Volatility ~~volatility~~ in the price of oil, gasoline, diesel, natural gas, RNG, or Environmental Attribute prices could adversely affect our business.

Historically, the prices of Environmental Attributes, RNG, natural gas, crude oil, gasoline and diesel have been volatile and this volatility may continue to increase in future. Factors that may cause volatility in the prices of Environmental Attributes, RNG, natural gas, crude oil, gasoline and diesel include, among others, (i) changes in supply and availability of crude oil, RNG and natural gas; (ii) governmental regulations; (iii) inventory levels; (iv) consumer demand; (v) price and availability of alternatives; (vi) weather conditions; (vii) negative publicity about crude oil or natural gas drilling; (viii) production or transportation techniques and methods; (ix) macro-economic environment and political conditions; (x) transportation costs; and (xi) the price of foreign imports. If the prices of crude oil, gasoline and diesel decline, or if the price of RNG or natural gas increases without corresponding increases in the prices of crude oil, gasoline and diesel or Environmental Attributes, we may not be able to offer our counterparties an attractive price advantage for our vehicle fuels. The market adoption of our vehicle fuels could be slowed or limited, and/or we may be forced to reduce the prices at which we sell our vehicle fuels in order to try and attract new counterparties or prevent the loss of demand from existing counterparties. In addition, we expect that natural gas and crude oil prices will remain volatile for the near future because of market uncertainties over supply and demand, including but not limited to the current state of the world economies, 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 to our counterparties. Conversely, lower natural gas prices reduce our revenue when the commodity cost is passed to our counterparties.

High natural gas prices adversely affect our operating margins when we cannot pass the increased costs to our counterparties. Conversely, lower natural gas prices reduce our revenue when the commodity cost is passed to our counterparties.

Pricing conditions may also exacerbate the cost differential between vehicles that use our vehicle fuels and gasoline or diesel-powered vehicles, which may lead operators to delay or refrain from purchasing or converting to vehicles running on our fuels. Generally, vehicles that use our fuels cost more initially than gasoline or diesel-powered vehicles because the components needed for a vehicle to use our vehicle fuels add to the vehicle’s base cost. Operators then seek to recover the additional base cost over time through a lower cost to use alternative vehicle fuels. Operators may, however, perceive an inability to timely recover these additional initial costs if alternative vehicle fuels are not available at prices sufficiently lower than gasoline and diesel. Such an outcome could decrease our potential customer base and harm our business prospects.

We face significant upward pricing pressure in the market with respect to our securing the biogas rights necessary for proposed new Biogas Conversion Projects and our conversion of existing Renewable Power rights to RNG rights on existing Biogas Conversion Projects that we plan to convert.

We must reach agreement with the prospective biogas project site owner or developer in order to secure the biogas rights necessary for each proposed Biogas Conversion Project. Additionally, each project typically requires a site lease, access easements, permits, licenses, rights of way or other similar agreements. Historically, in exchange for the biogas rights and additional agreements, we have paid the site owner and/or developer a royalty or other similar payment based on revenue generated by the project or volume of biogas used by the project. Over recent years, as competition for development of biogas conversion project sites has increased and biogas project site owners and developers have become more sophisticated, it has become increasingly common for the prospective biogas project site owners and developers to ask for or require larger royalties or similar payments in order to secure the biogas rights. In addition, it is becoming increasingly common for some prospective biogas project site owners or developers to ask for or require equity participation in the prospective project.

In addition, it is becoming increasingly common for some prospective biogas project site owners or developers to ask for or require equity participation in the prospective project.

In addition, we face similar pricing pressures when we attempt to renew our biogas rights on existing Biogas Conversion Projects at the end of their contractual periods and in situations where we plan to convert existing Renewable Power projects to RNG projects.

These pricing pressures could lead us to decide not to pursue certain prospective Biogas Conversion Projects or not to pursue the renewal or conversion of one or more existing Renewable Power projects and, accordingly, negatively impact our overall financial condition, results of operations and prospects. These pricing pressures could also impact the profitability of prospective Biogas Conversion Projects, and, accordingly, negatively impact our overall financial condition, results of operations and prospects.

We currently face declining market prices for LCFS credits specifically within California as well as significant upward pressure on the costs associated with dispensing RNG specifically within California to generate the LCFS credits.

The market prices for LCFS credits specifically within California have declined over the past year, and the market for dispensing RNG with relatively low CI scores in California has become increasingly competitive because of increasing supply of RNG with these relatively low CI scores. As such, fleet operators using vehicles fueled by natural gas have been able to demand RNG marketers like us provide them with greater economic incentives for allowing us to dispense the fuel at the Fueling Stations, typically in the form of a greater share of our marketing fee or a greater share in the monetary value of the Environmental Attributes we generate when dispensing the fuel. The persistence of the current California dynamic is dependent upon future market developments, and as such the LCFS credits that we generate and sell may or may not produce future revenue that is comparable to historical LCFS revenue.

A prolonged environment of low prices or reduced demand for Renewable Power could have a material adverse effect on our business prospects, financial condition and results of operations.

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

Increased rates of recycling and legislation encouraging recycling, increased use of waste incineration, advances in waste disposal technology, decreased demand for meat and livestock products could decrease the availability or change the composition of waste for biogas conversion project gas.

The volume and composition of LFG produced at open landfill sites depends in large 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 sent to landfills. There have been numerous federal and state regulations and initiatives over the recent 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, recycling and other similar efforts may have negative effects on the volume and proportion of biodegradable waste sent to landfill sites across the United States. As a consequence, the volume and composition of waste sent to landfill sites from which our Biogas Conversion Projects collect LFG could change, which could adversely affect our business operations, prospects, financial condition and operational results.

In addition, research and development activities are currently 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 could 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.

We currently use, and may continue in the future to use, forward-sale and hedging arrangements, to mitigate certain risks, but the use of such arrangements could have a material adverse effect on our results of operations.

We currently use, and may continue in the future to use, forward sales transactions to sell Environmental Attributes and Renewable Power before they are generated. In addition, we use interest rate swaps to manage interest rate risk. We may use other types of hedging contracts, including foreign currency hedges if we 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 such 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 such contracts. If the values of such contracts change in a manner that we do not anticipate, or if a counterparty fails to perform under such a contract, it could harm our business, financial condition, results of operations and cash flows.

Our ability to acquire, convert, develop and operate Biogas Conversion Projects, as well as expand production at current Biogas Conversion Projects, is subject to many risks.

Our business strategy includes (i) the conversion of LFG projects from Renewable Power to RNG production where we already ~~controls~~control biogas gas rights, (ii) growth through the procurement of LFG rights and manure rights to develop new RNG projects, (iii) the acquisition and expansion of existing Biogas Conversion Projects, and (iv) growth through the procurement of rights to other sources of biogas for production of additional transportation fuels and generation of associated Environmental Attributes. This strategy depends on our ability to successfully convert existing LFG projects and identify and evaluate acquisition opportunities and complete new Biogas Conversion Projects or acquisitions on favorable terms. However, we cannot guarantee that we will be able to successfully identify new opportunities, acquire additional biogas rights and develop new RNG projects or convert existing projects on favorable terms or at all. In addition, we may ~~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.~~

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 may also achieve growth through the expansion of production at certain of our current Biogas Conversion Projects as the related landfills and dairy farms are expanded or otherwise begin to produce more gas or manure, respectively, but we cannot guarantee that we will be able to reach or renew the necessary agreements with site owners on economically favorable terms or at all. If we are unable to successfully identify and consummate future Biogas Conversion Project opportunities or acquisitions of Biogas Conversion Projects, or expand RNG production at our current Biogas Conversion 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 Renewable Power to RNG production. During the conversion of existing projects, there may be a gap in revenue while the electricity project is offline until the conversion is completed and the new RNG facility commences operations, which may adversely affect our financial condition and results of operations.

Our ability to acquire, convert, develop and operate Biogas Conversion Projects, as well as expand production at current Biogas Conversion Projects, is subject to several additional risks, including:

•regulatory changes that affect the value of RNG and the associated Environmental Attributes, which could have a significant effect on the financial performance of our Biogas Conversion Projects and the number of potential Biogas Conversion 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 Biogas Conversion Projects;

•substantial construction risks, including the risk of delay, that may arise due to forces outside of our control, such as those related to engineering and environmental problems, inclement weather, inflationary pressures on materials and labor, and supply chain and labor disruptions that may result due to recent regulatory changes or otherwise;

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

•accidents involving personal injury or the loss of life;

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

•the ability to obtain financing for a Biogas Conversion Project on acceptable terms or at all and the need for substantially more capital than initially budgeted to complete Biogas Conversion 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, increased pricing on, and a delay in the timeliness of delivery of raw materials and components, necessary for the Biogas Conversion Projects to function or necessary for the conversion of a Biogas Conversion Projects from Renewable Power to RNG production;

•obtaining and keeping in good standing permits, authorizations and consents from local city, county, state and US federal government agencies and organizations;

•penalties, including potential termination, under short-term and long-term contracts for failing to produce or deliver a sufficient quantity and acceptable quality of RNG in accordance with our contractual obligations;

•unknown regulatory changes related to the transportation of RNG, which may increase the transportation cost for delivering under our contracts then in effect;

•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 Biogas Conversion Projects.

Any of these factors could prevent us from acquiring, developing, converting, operating or expanding our Biogas Conversion Projects, or otherwise adversely affect our business, growth potential, financial condition and results of operations.

Acquiring Biogas Conversion Projects involves numerous risks, including potential exposure to pre-existing liabilities, unanticipated costs in acquiring and implementing the project, and lack of or limited experience in new geographic markets.

The acquisition of existing Biogas Conversion Projects involves numerous risks, many of which may not be discoverable 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 dispensing agreements, and, for international projects, possible exposure to 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 Biogas Conversion 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.

Additional 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 counterparties 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 certain 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;

•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.

Our Biogas Conversion Projects face operational challenges, including among other things the breakdown or failure of equipment or processes or performance below expected levels of output or efficiency due to wear and tear of our ~~equipment, latent defects, design or operator errors, force majeure events, or lack of transmission capacity or other problems with third party interconnection and transmission facilities.~~

equipment, latent defects, design or operator errors, force majeure events, or lack of transmission capacity or other problems with third party interconnection and transmission facilities.

The ongoing operation of our Biogas Conversion Projects involves risks that include the breakdown or failure of equipment or processes or performance below expected levels of output or efficiency due to wear and tear of our equipment, latent defects, design or operator errors or force majeure events, among other factors. Operation of our Biogas Conversion Projects also involves risks that we will be unable to transport our product to our counterparties in an efficient manner due to a lack of 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. Biogas conversion project site owners and operators can also impact our production if, in the course of ongoing operations, they damage the site’s biogas 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 many of our agreements to deliver a minimum quantity of Renewable Power, RNG and/or the associated Environmental Attributes to the counterparty. Unless we can rely on a force majeure or other provisions in the related agreements, falling below such a threshold could subject us to financial expenses and penalties, as well as possible termination of key agreements and potential violations of certain permits, which could further impede our ability to satisfy production requirements. Therefore, any unexpected reduction in output at any of our Biogas Conversion Projects that leads to any of these outcomes could have a material adverse effect on our business, financial condition and results of operations.

25An unexpected reduction in RNG production by third-party producers of RNG with whom we maintain marketing agreements to purchase RNG and/or the associated Environmental Attributes, or their inability or refusal to deliver such RNG or Environmental Attributes as provided under such agreements, may have a material adverse effect on our results of operations and could adversely affect our performance under associated dispensing agreements.

An unexpected reduction in RNG production by third-party producers of RNG with whom we maintain marketing agreements to purchase RNG and/or the associated Environmental Attributes, or their inability or refusal to deliver such RNG or Environmental Attributes as provided under such agreements, may have a material adverse effect on our results of operations and could adversely affect or performance under associated dispensing agreements.

The success of our RNG business depends, in large part, on our ability to (i) secure, on acceptable terms, an adequate supply of RNG and/or Environmental Attributes from third-party producers, (ii) sell RNG in sufficient volumes and at prices that are attractive to counterparties and produce acceptable margins for us, and (iii) generate and monetize Environmental Attributes under applicable federal or state programs at favorable prices. If we fail to maintain and build new relationships with third party producers of RNG, we may be unable to supply RNG and the associated Environmental Attributes to meet the demand of our counterparties, which could adversely affect our business.

Our ability to dispense an adequate amount of RNG is subject to risks affecting RNG production. Biogas Conversion Projects that produce RNG often experience unpredictable production levels or other difficulties due to a variety of factors, including, among others, (i) problems with equipment, (ii) severe weather, pandemics, or other health crises, (iii) construction delays, (iv) technical difficulties, (v) high operating costs, (vi) limited availability, or unfavorable composition of collected feedstock gas, and (vii) plant shutdowns caused by upgrades, expansion or required maintenance. In addition, increasing demand for RNG will result in more robust competition for supplies of RNG, including from other vehicle fuel providers, gas utilities (which may have distinct advantages in accessing RNG supply including potential use of ratepayer funds to fund RNG purchases if approved by a utility’s regulatory commission) and other users and providers. If we or any of our third party RNG suppliers experience these or other difficulties in RNG production processes, or if competition for RNG development projects and supply increases, then our supply of RNG and our ability to resell it as a vehicle fuel and generate the associated Environmental Attributes could be jeopardized.

Construction, development and operation of our Biogas Conversion Projects involves significant risks and hazards.

Biogas Conversion Projects as well as construction and operation of Fueling Stations involve hazardous activities, including acquiring and transporting fuel, operating large pieces of rotating equipment and delivering our renewable electricity and RNG to interconnection and transmission systems, including gas pipelines. 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 hazards may result in curtailment or termination 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.

Our Biogas Conversion Projects facilities and Fueling Stations 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 our 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 our business operations and result in loss of service to our counterparties, as well as create significant expense to repair security breaches or system damage. In the past we have experienced cyber security breaches, which we believe have not had a significant impact on the integrity of our systems or the security of data, including personal information maintained by us, but there can be no assurance that any future breach or disruption will not have a material adverse effect on our business, financial condition or operations.

Furthermore, some of our facilities are located in areas prone to extreme weather conditions, most notably extreme cold. Certain of our other Biogas Conversion Projects and Fueling Stations as well as certain key vendors conduct their operations in other locations, such as California and Florida, 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 natural disasters 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 from such warranties or performance guarantees may not cover lost revenues, increased expenses or liquidated damages payments, should we experience equipment breakdown or non-performance by our 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 any or all circumstances and against any or 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 and 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.

Any losses not covered by insurance could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our failure to dispense a specified quality or quantity of RNG could have a material adverse effect on our financial condition and results of operations, by subjecting us to, among other things, possible penalties or terminations under the various contractual arrangements under which we operate, including pursuant to a purchase and sale agreement related to the sale of our Environmental Attributes.

Our RNG business consists of producing RNG from Biogas Conversion Projects, procuring RNG from third party producers, and dispensing this RNG to counterparties through Fueling Stations and other potential end markets to generate and monetize the associated Environmental Attributes. If we fail to produce and dispense a specified quality or quantity of RNG, our business may be adversely impacted.

As an RNG supplier the quality and quantity of RNG we produce at our Biogas Conversion Projects may be negatively affected by, among other things, lack of feedstock or the relative mix in the components of the feedstock, mechanical breakdowns, faulty technology, competitive markets or changes to the laws and regulations that mandate the use of renewable energy sources. In addition, we rely in part on third party suppliers to provide us with certain amounts of the specified quality and quantity of RNG that we are obligated to deliver under contractual commitments to our distribution counterparties but that we have not otherwise produced at our Biogas Conversion Projects.

If we are unable to obtain an adequate supply of RNG through a combination of Biogas Conversion Project production and supplies from third party RNG producers, we may be forced to pay a financial penalty under such contracts, including under a purchase and sale agreement under which we market a substantial majority of our Environmental Attributes through NextEra Energy Marketing, LLC (“NextEra”). Even if we are able to produce and obtain an adequate supply of RNG to satisfy the quantity requirements of our counterparties, RNG and the associated Environmental Attributes must also meet or exceed quality standards. If we and our third party suppliers are unable to meet applicable quality standards, through one or more of the factors discussed above or otherwise, we could be subject to financial penalties under such contracts.

In connection with the marketing of the Environmental Attributes generated from our activities, in November 2021, we signed a purchase and sale agreement with NextEra providing for the exclusive purchase by NextEra of 90% of our Environmental Attributes (RINs and LCFS credits), including those generated by our owned Biogas Conversion Projects and those granted to us in connection with dispensing of RNG on behalf of third-party projects. Under the agreement, we are to receive the net proceeds paid to NextEra by NextEra customers for the purchase of such Environmental Attributes (or in certain circumstances an index-based price or pre-negotiated price) less a specified discount. The agreement provides for an initial five year term, followed by automatic one-year renewals unless terminated by either party at least 90 days prior to the last day of the initial term or then-current renewal term.

Under the agreement, we have committed to sell a minimum quarterly volume of Environmental Attributes to NextEra, which if not satisfied on a cumulative basis (giving credit for certain excess volume sold to NextEra during the contract term) as of the end of the contract term (or upon an early termination of the agreement) would result in our paying NextEra a shortfall payment calculated by (i) multiplying the amount of the volume shortfall by a fraction of the then-current index price of the Environmental Attribute and (ii) adding a specified premium (the “Shortfall Amount”). Similarly, if the agreement is terminated by NextEra due to an event of default (generally defined as a failure by us to pay any undisputed amounts under the agreement, a material uncured breach of our representations or warranties or other obligations under the agreement, or the dissolution, bankruptcy or insolvency of us or certain of our affiliates), NextEra would be entitled to receive, without any duplication, any then-current Shortfall Amount plus an accelerated payment calculated based off of the remaining minimum quarterly volume commitments for the balance of the initial term (or for the next four quarters of the next renewal term, if neither party had provided notice of non-renewal as described above prior to the commencement of such renewal term), which accelerated payment would be similarly calculated by (i) multiplying such remaining minimum quarterly volume commitments by a fraction of the then-current index price of the Environmental Attribute and (ii) adding a specified premium. The amount of such potential payments declines over the course of the contract term as we deliver Environmental Attribute volume under the contract. Were, however, the agreement to be terminated as of the date of this report and we were not to deliver any further Environmental Attribute volume to NextEra under the agreement, the 29

Under the agreement, we are to receive the net proceeds paid to NextEra by NextEra customers for the purchase of such Environmental Attributes (or in certain circumstances an index-based price or pre-negotiated price) less a specified discount. The agreement provides for an initial five year term, followed by automatic one-year renewals unless terminated by either party at least 90 days prior to the last day of the initial term or then-current renewal term.

The amount of such potential payments declines over the course of the contract term as we deliver Environmental Attribute volume under the contract. If, however, the agreement was to be terminated as of the date of this report and we were not to deliver any further Environmental Attribute volume to NextEra under the agreement, the maximum potential payment to NextEra under these provisions would be approximately $9.9 million based on current market prices for such Environmental Attributes.

The success of our RNG projects depends on our ability to timely generate and ultimately receive certification of the Environmental Attributes associated with our RNG production and sale. A delay or failure in the certification of such Environmental Attributes could have a material adverse effect on the financial performance of our Biogas Conversion Projects.

We are required to register our RNG projects with the EPA and relevant state regulatory agencies. Further, we qualify our RINs through a voluntary Quality Assurance Plan, which typically takes from three to five months from first injection of RNG into the commercial pipeline system. Although no similar qualification process currently exists for LCFS credits, we expect such a process to be implemented and would expect to seek qualification on a state-by-state basis under such future programs. Delays in obtaining registration, RIN qualification, and any future LCFS credit qualification of a new project could delay future revenues from the project and could adversely affect our cash flow. Further, we typically make a large investment in the project prior to receiving the regulatory approval and RIN qualification. By registering each RNG project with the EPA’s voluntary Quality Assurance Plan, we are subject to quarterly third-party audits and semi-annual on-site visits of our projects to validate generated RINs and overall compliance with the RFS program. We are also subject to a separate third party’s annual attestation review. The Quality Assurance Plan provides a process for RIN owners to follow, for an affirmative defense to civil liability, if used or transferred Quality Assurance Plan verified RINs were invalidly generated. A project’s failure to comply could result in remedial action by the EPA, including penalties, fines, retirement of RINs, or termination of the project’s registration, any of which could adversely affect our business, financial condition and results of operations.

Maintenance, expansion and refurbishment of our Biogas Conversion Projects involve the risk of unplanned outages or reduced output, resulting from among other things periodic upgrading and improvement, unplanned breakdowns in equipment, and forced outages.

Our Biogas Conversion Project 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 earn profits and adversely affect our business, financial condition and results of operations. If we make major modifications to our facilities, such modifications may result in material additional capital expenditures. We may also choose to repower, refurbish or upgrade our facilities based on our assessment that such expenditures will provide adequate financial returns. Such facility modifications require time 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 renewable natural gas prices. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In order to secure development, operational, dispensing and other necessary contract rights for our Biogas Conversion 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 Biogas Conversion Projects generally lasts from 20 to 48 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 Biogas Conversion 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 4 to 12 months or longer for the Biogas Conversion 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 Biogas Conversion Projects may not produce expected levels of output, and the amount of Renewable Power or RNG actually produced at each of our respective projects will vary over time, and, therefore so will generation of associated Environmental Attributes.

Our Biogas Conversion Projects rely on organic material, the decomposition of which causes the generation of gas consisting primarily of methane. The Biogas Conversion Projects use such methane gas to generate Renewable Power or RNG. The estimation of biogas 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 site. Production levels are subject to a number of additional risks, including (i) a failure or wearing out of our or our landfill operators’, counterparties’ or utilities’ equipment; (ii) an inability to find suitable replacement equipment or parts; (iii) less than expected supply or quality of the project’s source of biogas and faster than expected diminishment of such biogas supply; or (iv) volume disruption in our fuel supply collection system. As a result, the volume of Renewable Power or RNG generated from such sites may in the future vary from our initial estimates, and those variations may be material. In addition, we have in the past incurred, and may in the future incur, material asset impairment charges if any of our Biogas Conversion Projects incur operational issues that indicate our expected future cash flows from the relevant 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.

Any such impairment charge could adversely affect our operating results in the period in which the charge is recorded.

In addition, in order to maximize collection of LFG, we may need to take various measures, such as drilling additional gas wells in the landfill sites to increase LFG collection, balancing the pressure on the gas field based on the data collected by the landfill site 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 LFG projects is dependent in part on the actions of the landfill site owners and 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 that may be collected from a landfill site, resulting in a lower gas yield.

Biogas projects utilizing other types of feedstock, specifically livestock waste and dairy farm projects, typically produce significantly less RNG than landfill facilities. As a result, the commercial viability of such projects is more dependent on various factors and market forces outside of our control, such as changes to law or regulations that could affect the value of such projects or the incentives available to them. In addition, there are other factors currently unknown to us that may affect the commercial viability of other types of feedstock. Moreover, fluctuations in manure supply, the end use markets and the spread of diseases among herds could have a material impact on the success and completion of our Biogas Conversion Projects. As such, continued expansion into other types of feedstock could adversely affect our business, financial condition, and results of operations.

Our business plans include expanding from Renewable Power and RNG production projects into additional transportation-related infrastructure, including production and development of hydrogen vehicle Fueling Stations. Any such expansions may present unforeseen challenges and result in a competitive disadvantage relative to our more-established competitors in the markets into which we wish to expand.

We currently operate Biogas Conversion Projects that convert primarily landfill biogas into Renewable Power and RNG. However, we are actively developing projects that use anaerobic digesters to capture and convert emissions into low-carbon RNG, electricity and green hydrogen, and may expand into additional feedstocks in the future. We are also actively developing hydrogen fueling infrastructure. In addition, we are actively considering expansion into other lines of business, including carbon sequestration and Renewable Power for our projects, and the production of green hydrogen. These initiatives 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 renewable hydrogen sourced from a number of our projects’ RNG, and we may enter into long-term fixed price off-take contracts for green hydrogen that we may produce at our projects.

We are currently working with a leading developer of on-site hydrogen generators to put in place construction design and services agreements in order to develop hydrogen gas-as-a-service offerings at Fueling Stations. We do not have an operating history in the green hydrogen market and our forecasts are based on uncertain operations in the future.

Some LFG 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 LFG projects. If we invest, directly or indirectly, in an electric transmitting LFG project that allows us to exercise transmission market power, FERC could require our affiliates with MBR 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.

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.

Our gas and manure rights agreements for Biogas Conversion Projects are subject to certain conditions. A failure to satisfy such conditions could result in the loss of such rights.

Our gas and manure rights agreements for Biogas Conversion Projects 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 biogas conversion project site owner without any reimbursement of any portion of the purchase price paid for the gas or manure rights or any other amounts we have invested in the project. Delays in construction or delivery of equipment may result in our failing to meet the commercial operations deadline in a gas or manure rights agreement. The denial or loss of a permit essential to a Biogas Conversion Project could impair our ability to construct or operate a project as required under the relevant 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.

Furthermore, certain of our gas and manure rights agreements for Biogas Conversion Projects require us to purchase a certain amount of LFG and manure, respectively. 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 dairy farm, or covered by force majeure provisions in the relevant agreement, could result in failure to purchase the required amount of LFG or manure and the loss of these gas rights. Our gas and manure rights agreements often grant us the right to build additional generation capacity in the event of increased supply, but failure to use such increased supply after a prescribed period of time can result in the loss of these rights. In addition, we typically need approval from landfill owners in order to implement Renewable Power-to-RNG conversion projects, and we are also dependent on landfill owners for additional gas rights as well as land leases and easements for these conversion projects.

Our commercial success depends in part on our ability to identify, acquire, develop and operate public and private Fueling Stations for public and commercial fleet vehicles in order to dispense RNG for use as vehicle fuel and generate the associated Environmental Attributes.

Our specific focus on RNG to be used as a transportation fuel in the United States exposes us to risks related to the supply of and demand for RNG and the associated Environmental Attributes, the cost of capital expenditures, governmental regulation, and economic conditions, among other factors. As an RNG dispenser 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: (i) changes in pipeline gas quality standards or other regulatory changes that may limit our ability to transport RNG on pipelines or increase the costs of processing RNG; (ii) construction risks, including the risk of delay, that may arise because of inclement weather or labor disruptions; (iii) operating risks and the effect of disruptions on our business; (iv) budget overruns and exposure to liabilities because of unforeseen environmental, construction, technological or other complications; (v) failures or delays in obtaining desired or necessary rights, including leases and feedstock agreements; and (vi) failures or delays in obtaining and keeping in good standing permits, authorizations and consents from local city, county, state and US federal government agencies and organizations. Any of these factors could prevent completion or operation of projects, or otherwise adversely affect our business, financial condition, and results of operations.

Our success is dependent on the willingness of commercial fleets and other counterparties to adopt, and continue use of RNG, which may not occur in a timely manner, at expected levels or at all. Our vehicle fleet counterparties may choose to invest in renewable vehicle fuels other than RNG.

Our success is highly dependent on the adoption by commercial fleets and other consumers of natural gas vehicle fuels, which has been slow, volatile and unpredictable in many sectors. For example, adoption and deployment of natural gas in heavy and medium-duty trucking has been slower and more limited than we anticipated. If the market for natural gas vehicle fuels does not develop at improved rates or levels, or if a market develops but we are not able to capture a significant share of the market or the market subsequently declines, our business, growth potential, financial condition, and operating results would be harmed.

Additional factors that may influence the adoption of natural gas vehicle fuels, many of which are beyond our control, include, among others:

•lack of demand for trucks that use natural gas vehicle fuels due to business disruptions and depressed oil prices;

•adoption of governmental policies or programs or increased publicity or popular sentiment in favor of vehicles or fuels other than natural gas, including long-standing support for gasoline and diesel-powered vehicles, changes to emissions requirements applicable to vehicles powered by gasoline, diesel, natural gas, or other vehicle fuels and/or growing support for electric and hydrogen-powered vehicles;

•perceptions about the benefits of natural gas vehicle fuels relative to gasoline, diesel and other alternative vehicle fuels, including with respect to factors such as supply, cost savings, environmental benefits and safety;

•the volatility in the supply, demand, use and prices of crude oil, gasoline, diesel, RNG, natural gas and other vehicle fuels, such as electricity, hydrogen, renewable diesel, biodiesel and ethanol;

•inertia among fleets and fleet vehicle operators, who may be unable or unwilling to prioritize converting a fleet to our vehicle fuels over an operator’s other general business concerns, particularly if the operator is not sufficiently incentivized by emissions regulations or other requirements or lacks demand for the conversion from its counterparties or drivers;

•vehicle cost, fuel efficiency, availability, quality, safety, convenience (to fuel and service), design, performance and residual value, as well as operator perception with respect to these factors, generally and in our key customer markets and relative to comparable vehicles powered by other fuels;

•the development, production, cost, availability, performance, sales and marketing and reputation of engines that are well-suited for the vehicles used in our key customer markets, including heavy and medium-duty trucks and other fleets;

•increasing competition in the market for vehicle fuels generally, and the nature and effect of competitive developments in such market, including improvements in or perceived advantages of other vehicle fuels and engines powered by such fuels;

•the availability and effect of environmental, tax or other governmental regulations, programs or incentives that promote our products or other alternatives as a vehicle fuel, including certain programs under which we generate Environmental Attributes by selling RNG as a vehicle fuel, as well as the market prices for such credits; and

•emissions and other environmental regulations and pressures on producing, transporting, and dispensing our fuels.

Acquisition, financing, construction, and development of Fueling Station projects by us or our partners that own projects may not commence on anticipated timelines or at all.

Our strategy is to continue to expand, including through the acquisition of additional Fueling Station projects and by signing additional supply agreements with third party project owner partners. From time to time we and our partners enter into nonbinding letters of intent for projects. Until the negotiations are final, however, and the parties have executed definitive documentation, we or our partners may not be able to consummate any development or acquisition transactions, or any other similar arrangements, on the terms set forth in the applicable letter of intent or at all.

The acquisition, financing, construction and development of projects involves numerous risks, including:

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

•failure to obtain all necessary rights to land access and use;

•inaccuracy of assumptions with respect to the cost and schedule for completing construction;

•inaccuracy of assumptions with respect to the biogas potential, including quality, volume, and asset life;

•the ability to obtain financing for a project on acceptable terms or at all;

•delays in deliveries or increases in the price of equipment or other materials;

•permitting and other regulatory issues, license revocation and changes in legal requirements;

•increases in the cost of labor, labor disputes and work stoppages or the inability to find an adequate supply of workers;

•failure to receive quality and timely performance of third-party services;

•unforeseen engineering and environmental problems;

•cost overruns or supply chain disruptions;

•accidents involving personal injury or the loss of life;

•weather conditions, health crises, pandemics, catastrophic events, including fires, explosions, earthquakes, droughts and acts of terrorism, and other force majeure events; and

•interconnection and access to utilities.

In addition, new projects have no operating history. A new project may be unable to fund principal and interest payments under its debt service obligations or may operate at a loss.

Our Fueling Station construction activities for commercial fleets and other counterparties are subject to business and operational risks, including predicting demand in a particular market or markets, land use, permitting or zoning difficulties, responsibility for actions of sub-contractors on jobs in which we serve as general contractor, potential labor shortages and cost overruns.

As part of our business activities, we design and construct Fueling Stations that we either own and operate ourselves or provide these services for our counterparties. 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 may build Fueling Stations that we may not open for fueling operations, and we may open Fueling 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 specific locations or for other reasons. For any Fueling Stations that are completed but unopened, we would have substantial investments in assets that do not produce revenue, and for Fueling Stations that are open and underperforming, we may decide to close them.

We also face many operational challenges in connection with our Fueling Station design and construction activities. For example, we may not be able to identify suitable locations for the Fueling Stations we or our counterparties 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 the COVID-19 pandemic, any of which could prevent us or our counterparties from building new stations on such 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.

reduced operations of permitting agencies because of the COVID-19 pandemic, any of which could prevent us or our counterparties from building new stations on such 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 Fueling Station construction and facility modification projects, and we typically rely on licensed subcontractors to perform the construction work. We may be liable for any damage we or our subcontractors cause or for injuries suffered by our employees or our subcontractors’ employees during the course of work on our projects. Additionally, shortages of skilled subcontractor labor and any supply chain disruptions affecting access to and cost of construction materials could significantly delay a project or otherwise increase our costs. Further, our expected profit from a project is based in part on assumptions about the cost of the project, and cost overruns, delays or other execution issues may, in the case of projects we complete and sell to counterparties, result in our failure to achieve our expected margins or cover our costs, and in the case of projects we build and own, result in our failure to achieve an acceptable rate of return. If any of these events occur, our business, operating results and cash flows could be negatively affected.

Certain of our Biogas Conversion Projects and Fueling Stations are newly constructed or are under construction and may not perform as we expect.

We have a number of Biogas Conversion Projects under construction that will begin production over the next 18-24 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 forecasts with respect to our new and developing projects, and related estimates and assumptions, are based on limited operating history or expected operating results. 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.

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.

Our contracts with government entities may be subject to unique risks, including possible termination of or reduction in the governmental programs under which we operate, instances in which our contract provisions allow the government entity to terminate, amend or change terms at their convenience, and competitive bidding processes for the award of contracts.

We have, and expect to continue to seek, long-term Fueling Station construction, maintenance and fuel sale contracts with various government entities. 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 could result in the loss of anticipated future revenue attributable to such 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.

In addition, government contracts are frequently awarded only after competitive bidding processes, which are often protracted. In many cases, unsuccessful bidders for government contracts are provided the opportunity to formally protest the contract awards through various agencies or other administrative and judicial channels. The protest process may substantially delay a successful bidder’s contract performance, result in cancellation of the contract award entirely and distract management. As a result, we may not be awarded contracts for which we bid, and substantial delays or cancellation of government contracts may follow any successful bids as a result of any protests by other bidders. The occurrence of any of these risks could have a material adverse effect on our results of operations and financial condition.

Our cash could be adversely affected if the financial institutions in which we hold our cash fail.

The Company maintains domestic cash deposits in Federal Deposit Insurance Corporation (“FDIC”) insured banks. The domestic bank deposit balances may exceed the FDIC insurance limits. These balances could be impacted if one or more of the financial institutions in which we deposit monies fails or is subject to other adverse conditions in the financial or credit markets.

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

We have incurred net losses historically. 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 common stock to fall. Furthermore, historical losses may not be indicative of future losses due to many factors outside of our control 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 notes to the financial statements 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 adverse effects on our financial condition, our results of operations and the trading price of common stock.

Loss of our key management could adversely affect our business performance. Our management team has limited experience in operating a public company such as us.

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 Class A common stock.

Failure to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business and operating results. In addition, current and potential stockholders could lose confidence in our financial reporting, which could have a material adverse effect on the price of our Class A common stock.

Section 404 of the Sarbanes-Oxley Act requires annual management assessments of the effectiveness of our internal control over financial reporting and a report by our independent registered public accounting firm on the effectiveness of internal control over financial reporting as of year-end. We are required to report, among other things, control deficiencies that constitute material weaknesses or changes in internal control that, or that are reasonably likely to, materially affect internal control over financial reporting. A “material weakness” is a significant deficiency or combination of significant deficiencies that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

We have identified and remediated control deficiencies in the past, and we cannot assure you that we will at all times in the future be able to report that our internal controls are effective. If we cannot provide reliable financial reports or prevent fraud, our results of operation could be harmed. Our failure to maintain the effective internal control over financial reporting could cause the cost related to remediation to increase and could cause our stock price to decline. In addition, we may not be able to accurately report our financial results, may be subject to regulatory sanctions, and investors may lose confidence in our financial statements. No material weaknesses were identified during the year ended December 31, 2024.36

internal control over financial reporting. A “material weakness” is a significant deficiency or combination of significant deficiencies that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

Litigation or legal proceedings could expose us to significant liabilities and have a negative impact on our reputations or business.

We may become subject to claims, litigation, disputes and other legal proceedings from time to time. We evaluate these claims, litigation, disputes and other legal proceedings to assess the likelihood of unfavorable outcomes and to estimate, if possible, the amount of potential losses. Based on these assessments and estimates, we may establish reserves, as appropriate. These assessments and estimates are based on the information available to each management team at the time of its respective assessment and involve a significant amount of management judgment. Actual outcomes or losses may differ materially from our assessments and estimates.

Even when not merited or whether or not we ultimately prevail, the defense of these lawsuits may divert management’s attention, and we may incur significant expenses in defending these lawsuits. The results of litigation and other legal proceedings are inherently uncertain, and adverse judgments or settlements in some of these legal disputes may result in adverse monetary damages, penalties or injunctive relief against us which could negatively impact any of our financial positions, cash flows or results of operations. Further, any liability or negligence claim against us in US courts may, if successful, result in damages being awarded that contain punitive elements and therefore may significantly exceed the loss or damage suffered by the successful claimant. Any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or to obtain adequate insurance in the future. A settlement or an unfavorable outcome in a legal dispute could have an adverse effect on our business, financial condition, results of operations, cash flows and/or prospects.

Furthermore, while we maintain insurance for certain potential liabilities, such insurance does not cover all types and amounts of potential liabilities and is subject to various exclusions as well as caps on amounts recoverable. Even if we believe a claim is covered by insurance, insurers may dispute its entitlement to recovery for a variety of potential reasons, which may affect the timing and, if the insurers prevail, the amount of our recovery.

Our business and operations could be negatively affected if we become subject to any securities litigation or shareholder activism, which could cause us to incur significant expense, hinder execution of business and growth strategy and impact its stock price.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Shareholder activism, which could take many forms or arise in a variety of situations, has been increasing recently. Volatility in the stock price of our Class A common stock or other reasons may in the future cause it to become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert management’s and our board’s attention and resources from our business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to our future, adversely affect our relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, we may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, our stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

Our only material assets are our direct interests in OPAL Fuels, and we are accordingly dependent upon distributions from OPAL Fuels to pay dividends and taxes and other expenses.

We are a holding company and have no material assets other than our ownership of Class A units in OPAL Fuels. We therefore have no independent means of generating revenue. We intend to cause our subsidiaries (including OPAL Fuels) to make distributions in an amount sufficient to cover all applicable taxes and other expenses payable and dividends, if any, declared by us. The agreements governing our debt facilities impose, and agreements governing our future debt facilities are expected to impose, certain restrictions on distributions by such subsidiaries to us, and may limit our ability to pay cash dividends. The terms of any credit agreements or other borrowing arrangements that we may enter into in the future may impose similar restrictions. To the extent that we need funds, and any of our direct or indirect subsidiaries is restricted from making such distributions under these debt agreements or applicable law or regulation, or is otherwise unable to provide such funds, it could materially adversely affect our liquidity and financial condition.

If we are deemed an “investment company” under the Investment Company Act as a result of our ownership of OPAL Fuels, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on its business.

A person may be deemed to be an “investment company” for purposes of the Investment Company Act if it owns investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items), absent an applicable exemption. We have no material assets other than our interests in OPAL Fuels. As managing member of OPAL Fuels, we generally have control over all of the affairs and decision making of OPAL Fuels. On the basis of our control over OPAL Fuels, we believe our direct interest in OPAL Fuels is not an “investment security” within the meaning of the Investment Company Act. If we were to cease participation in the management of OPAL Fuels, however, our interest in OPAL Fuels could be deemed an “investment security,” which could result in our being required to register as an investment company under the Investment Company Act and becoming subject to the registration and other requirements of the Investment Company Act.

The Investment Company Act and the rules thereunder contain detailed parameters for the organization and operations of investment companies. Among other things, the Investment Company Act and the rules thereunder limit or prohibit transactions with affiliates, impose limitations on the issuance of debt and equity securities, prohibit the issuance of stock options and impose certain governance requirements. We intend to conduct our operations so that we will not be deemed to be an investment company under the Investment Company Act. However, if anything were to happen which would require us to register as an investment company under the Investment Company Act, requirements imposed by the Investment Company Act, including limitations on its capital structure, ability to transact business with affiliates and ability to compensate key employees, could make it impractical for us to continue our business as currently conducted, impair the agreements and arrangements between and among us, OPAL Fuels, members of their respective management teams and related entities or any combination thereof and materially adversely affect our business, financial condition and results of operations.

In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits that we realize in respect of the tax attributes subject to the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we determine, and the IRS or another tax authority may challenge all or a part of the existing tax basis, tax basis increases, or other tax attributes subject to the Tax Receivable Agreement, and a court could sustain such challenge. The parties to the Tax Receivable Agreement will not reimburse us for any payments previously made if such tax basis is, or other tax benefits are, subsequently disallowed, except that any excess payments made to a party under the Tax Receivable Agreement will be netted against future payments otherwise to be made under the Tax Receivable Agreement, if any, after the determination of such excess.

If we experience a change of control (as defined under the Tax Receivable Agreement, which includes certain mergers, any plan of liquidation and other forms of business combinations or changes of control) or the Tax Receivable Agreement terminates early (at our election or as a result of a breach, including a breach for our failing to make timely payments under the Tax Receivable Agreement for more than three months, except in the case of certain liquidity exceptions), we could be required to make a substantial, immediate lump-sum payment based on the present value of hypothetical future payments that could be required under the Tax Receivable Agreement. The calculation of the hypothetical future payments would be made using certain assumptions and deemed events set forth in the Tax Receivable Agreement, including (i) the sufficiency of taxable income to fully utilize the tax benefits, (ii) any OPAL Fuels Common Units (other than those held by us) outstanding on the termination date are exchanged on the termination date and (iii) the utilization of certain loss carryovers over a certain time period. Our ability to generate net taxable income is subject to substantial uncertainty. Accordingly, as a result of the assumptions, the required lump-sum payment may be significantly in advance of, and could materially exceed, the realized future tax benefits to which the payment relates.

As a result of either an early termination or a change of control, we could be required to make payments under the Tax Receivable Agreement that exceed our actual cash savings. Consequently, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. For example, assuming no material changes in the relevant tax law, we expect that if we experienced a change of control the estimated Tax Receivable Agreement lump-sum payment would be approximately $133.0 million depending on OPAL Fuels’ rate of recovery of the tax basis increases associated with the deemed exchange of the OPAL Fuels Common Units (other than those held by us). This estimated Tax Receivable Agreement lump-sum payment is calculated using a discount rate equal to 7.47%, applied against an undiscounted liability of approximately $240.8 million. These amounts are estimates and have been prepared for informational purposes only. The actual amount of deferred tax assets and related liabilities that we will recognize will differ based on, among other things, the timing of the exchanges, the price of the shares of Class A common stock at the time of the exchange, and the tax rates then in effect. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

It is more likely than not that the deferred tax assets will not be realized in accordance with ASC Topic 740, ‘Income Taxes’. As such, the Company has reduced the full carrying amount of the deferred tax assets with a valuation allowance under both scenarios. Management will continue to monitor and consider the available evidence from quarter to quarter, and year to year, to determine if more or less valuation allowance is required at that time.38

Finally, because we are a holding company with no operations of our own, our ability to make payments under the Tax Receivable Agreement depends on the ability of OPAL Fuels to make distributions to us. To the extent that OPAL is unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid, which could negatively impact our results of operations and could also affect our liquidity in periods in which such payments are made.

Our increasing reliance on information technology and other systems subjects us to risks associated with cybersecurity. Cybersecurity incidents or our failure to maintain the security and integrity of Company, employee, associate, customer or third-party data could have a disruptive effect on our business and adversely affect our reputation and financial performance.

A failure of our IT and data security infrastructure could have a material adverse effect on our business and operations. We rely upon the expertise, reliability and security of our outsourced IT provider and their services to expand and continually update this infrastructure in response to the changing needs of our business. Our existing IT systems and any new IT systems may not perform as expected. If we experience a problem with the functioning of any important IT system or a security breach of our network, including during system upgrades or new system implementations, the resulting disruptions could have a material adverse effect on our business.

We and some of our third-party vendors receive and store personal information in connection with our human resources operations and other aspects of our business. Despite our implementation of reasonable security measures, our IT systems, like those of other companies, are vulnerable to damages from computer viruses, natural disasters, fire, power loss, telecommunications failures, personnel misconduct, human error, unauthorized access, physical or electronic security breaches, cyber-attacks (including malicious and destructive code, phishing attacks, ransomware, and denial of service attacks), and other similar disruptions. Cybersecurity threat actors employ a wide variety of methods and techniques that are constantly evolving, increasingly sophisticated, and difficult to detect and successfully defend against.

Cybersecurity incidents could expose us to claims, litigation, regulatory or other governmental investigations, administrative fines and potential liability. A material network breach in the security of our IT systems could include the theft of our trade secrets, customer information, human resources information or other confidential data, including but not limited to personally identifiable information, that could have a material adverse effect on our business, financial condition, or results of operations.

Many governments have enacted laws requiring companies to provide notice of cyber incidents involving certain types of data, including personal data. Any compromise of our security could result in a violation of applicable domestic and foreign security, privacy or data protection, consumer and other laws, regulatory or other governmental investigations, enforcement actions, and legal and financial exposure, including potential contractual liability that could have a material adverse effect on our business. In addition, we may be required to incur significant costs to protect against and remediate damage caused by these disruptions or security breaches in the future that could have a material adverse effect on our business.

As a renewable energy producer, we face various security threats, including among others, computer viruses, malware, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over the internet, attachments to emails, persons with access to systems inside our organization, cybersecurity threats to gain unauthorized access to sensitive information or to expose, exfiltrate, alter, delete or render our data or systems unusable, threats to the security of our ~~projects and infrastructure or third-party facilities and infrastructure, such as processing projects and pipelines, natural disasters, threats from terrorist acts and war.~~

projects and infrastructure or third-party facilities and infrastructure, such as processing projects and pipelines, natural disasters, threats from terrorist acts and war.

We take various steps to identify and mitigate potential cybersecurity threats. As cyber incidents become more frequent and the sophistication of threat actors increases, our associated cybersecurity costs are expected to increase. Specifically, we expect to implement several incremental cybersecurity improvements over the next 18 to 36 months to enhance our defensive capabilities and resilience. Despite our ongoing and anticipated cybersecurity efforts, a successful cybersecurity incident could lead to additional material costs, including those related to the loss of sensitive information, repairs to infrastructure or capabilities essential to our operations, responding to litigation or regulatory investigations, and those related to a material and adverse impact on our reputation, financial position, results of operations, or cash flows.

Our business may be impacted by macroeconomic conditions, including fears concerning the financial services industry, inflation, rising interest rates and volatile market conditions, and other uncertainties beyond our control.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank failed and was taken into receivership by the Federal Deposit Insurance Corporation; on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership; the following week, a syndicate of U.S. banks infused $30 billion in First Republic Bank; and later that same week, the Swiss Central Bank provided $54 billion in covered loan and short-term liquidity facilities to Credit Suisse Group AG, all in an attempt to reassure depositors and calm fears of a banking contagion. Our ability to effectively run our business could be adversely affected by general conditions in the global economy and in the financial services industry. Various macroeconomic factors could adversely affect our business, including fears concerning the banking sector, changes in inflation, interest rates and overall economic conditions and uncertainties. A severe or prolonged economic downturn could result in a variety of risks, including our ability to raise additional funding on a timely basis or on acceptable terms. A weak or declining economy could also impact third parties upon whom we depend on to run our business. Increasing concerns over bank failures and bailouts and their potential broader effects and potential systemic risk on the banking sector generally and on the biotechnology industry and its participants may adversely affect our access to capital and our business and operations more generally. Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial institutions with which we have arrangements directly, or the financial services industry or economy in general.

37Currently, we do not have a business relationship with any of the banking institutions mentioned above, and our cash and cash equivalents have been unaffected by the turmoil in the financial industry; however, we cannot guarantee that the banking institution with which we do business will not face similar circumstances in the future, or that the third parties with whom we do business will not be negatively affected by such circumstances.

Risks Related to Regulations or Governmental Actions

Our operations are subject to numerous stringent EHS laws and regulations that may expose us to significant costs and liabilities. From time to time, we have been issued notices of violations from government entities that our operations have failed to comply with such laws and regulations. Failure to comply with such 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.

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, and the health and safety of our employees and other persons.

These laws and regulations impose numerous obligations applicable to our operations, including the acquisition of permits before construction and operation of our Biogas Conversion Projects and Fueling Stations; 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 Biogas Conversion Projects and Fueling Stations. 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 to obtain or review. 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 permitting requirements can necessitate expensive pollution control equipment or operational changes to limit actual or potential impacts to the environment.

require considerable technical documentation and analysis, and sometimes require long time periods to obtain or review. 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 permitting requirements can necessitate expensive pollution control equipment or operational changes to limit actual or potential impacts to the environment.

Our operations inherently risk incurring significant environmental costs and liabilities due to the need to manage waste and emissions from our Biogas Conversion Projects and Fueling Stations. Spills or other releases of regulated substances, including spills and releases that may 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, rules 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 of Biogas Conversion Projects and Fueling Stations, 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, rules 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 and turbine engines we use to generate Renewable Power from landfill biogas. 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 already in place have caused us to not be able to operate some of our electric generating equipment in areas of that state. If other states were to follow California’s lead, we could face challenges in maintaining our electric generating operations and possibly, other operations in such jurisdictions.

Continued governmental and public emphasis on environmental issues can be expected to result in increased future investments for environmental control compliance at our facilities. Present and future environmental laws, rules and regulations, and interpretations of such laws, rules and regulations, applicable to our operations, more vigorous enforcement policies and discovery of currently unknown conditions may require substantial costs or expenditures that could have a material adverse effect on our business, results of operations and financial condition. In January 2021, the current US presidential administration signed multiple executive orders related to the climate and environment. These executive orders (i) direct federal agencies to review and reverse more than one hundred actions taken by the previous US presidential administration on or relating to the environment, (ii) 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, (iii) establish the National Climate Task Force, which assembles leaders from across twenty one federal agencies and departments, (iv) commit to environmental justice and new, clean infrastructure projects, (v) commence development of emissions reduction targets and (vi) establish the special presidential envoy for climate on the National Security Council. At this time, we cannot predict the outcome of any of these or any future executive orders on our operations.

Existing and 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.

The markets for Renewable Power, RNG and the associated Environmental Attributes are influenced by US federal and state governmental regulations and policies concerning such resources. These regulations and policies are frequently modified, which could result in a significant future reduction in the potential demand for Renewable Power, RNG and the associated Environmental Attributes. Any new governmental regulations applicable to our Biogas Conversion Projects or markets for Renewable Power, RNG or the associated Environmental Attributes may result in significant additional expenses or related development costs and as a result, could cause a significant reduction in demand by our current and future counterparties. Failure to comply with such requirements could result in (i) the disconnection and/or shutdown of the non-complying facility, (ii) our inability to sell Renewable Power or RNG from the non-complying facility, (iii) penalties and defaults arising from contracts with respect to production from the non-complying facility, (iv) the imposition of liens, fines, refunds and interest, and/or civil or criminal liability and (v) delays or failures in the development of new Biogas Conversion Projects and Fueling Stations.

The EPA annually sets proposed and actual RVOs for the RIN market in accordance with the mandates established by EISA. The EPA’s issuance of timely and sufficient annual RVOs to accommodate the RNG industry’s growing production levels may be needed to stabilize the RIN market. The EPA annually sets proposed RVOs for D3 (cellulosic biofuel with a 60% GHG reduction requirement) RINs in accordance with the mandates established by the EISA. In June 2023, the EPA set RVOs for 2023 through 2025 via a new Set rule.

There can be no assurance that the EPA will timely set annual RVOs in the future or that the RVOs will continue to increase or be sufficient to satisfy the growing supply of RNG which may be targeted for the U.S. transportation fuel market. The EPA may set RVOs inaccurately or inconsistently, and the manner in which the EPA sets RVOs may change under legislative or regulatory revisions. Uncertainty as to how the Renewable Fuel Standard (“RFS”) program will continue to be administered and supported by the EPA under the current US presidential administration can create price volatility in the RIN market. Given this regulatory uncertainty, we cannot assure that (i) we will be able to monetize RINs at the same price levels as we have in the past, (ii) production shortfalls will not impact our ability to monetize RINs at favorable current pricing, and (iii) the rising price environment for RINs will continue.

On the state level, the economics of RNG are enhanced by low-carbon fuel initiatives, particularly a well-established LCFS program in California and similar developing programs in Oregon and Washington (with several other states also actively considering similar initiatives). In California’s case, in 2009, the California Air Resources Board adopted LCFS regulations aimed at reducing the 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. Under the California and California-type LCFS programs, 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 build out of infrastructure. The California Air Resources Board awards these credits to RNG projects based on such 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 that we will be able to maintain or reduce our CI score to monetize LCFS credits generated from our Biogas Conversion Projects. If we are unable to sell LCFS credits, it could adversely affect our business.

We cannot assure that we will be able to maintain or reduce our CI score to monetize LCFS credits generated from our Biogas Conversion Projects. If we are unable to sell LCFS credits, it could adversely affect 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 in general, or at unattractive prices, could adversely affect our business.

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. These programs and regulations, which encourage the use of RNG as a vehicle fuel, could 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 programs and regulations that promote RNG. Many of these parties have substantial resources and influence. Further, changes in federal, state or local political, social or economic conditions, including a lack of legislative focus on these programs and regulations, could result in their modification, delayed adoption or repeal. Any failure to adopt, delay in implementing, expiration, repeal or modification of these programs and regulations, or the adoption of any programs or regulations that encourage the use of other alternative fuels or alternative vehicles over RNG, could reduce the market demand for RNG as a vehicle fuel and harm our operating results, liquidity, and financial condition.

For instance, in certain states, including California, lawmakers and regulators have implemented various measures designed to increase the use of electric, hydrogen and other zero-emission vehicles, including establishing firm goals for the number of these vehicles operating on state roads by specified dates and enacting various laws and other programs in support of these goals. Although the influence and applicability of these or similar measures on our business remains uncertain, a focus on “zero tailpipe emissions” vehicles over vehicles such as those operating on RNG that have an overall net carbon negative emissions profile, but some tailpipe emissions, could adversely affect the market for our fuels.

All of our current electric generating facilities are qualifying small power production facilities (“QFs”) under the Federal Power Act and the Public Utility Regulatory Policies Act of 1978, as amended. We are permitted to make wholesale sales (that is, sales for resale) of renewable electricity, capacity, and ancillary services from our QFs with a net generating capacity that does not exceed 20 megawatts or that is an “eligible” facility as defined by section 3(17)(E) of the Federal Power Act without (a) obtaining authorization by FERC pursuant to the Federal Power Act to sell electric energy, capacity and/or ancillary services at market-based rates, (b) acceptance by FERC of a tariff providing for such sales, and (c) granting by FERC of such regulatory waivers and blanket authorizations as are customarily granted by FERC to holders of market-based rate authority, including blanket authorization under section 204 of the Federal Power Act to issue securities and assume liabilities (“MBR Authority”) or any other approval from the U.S. Federal Energy Regulatory Commission (“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 Congress could amend the Federal Power Act and eliminate QF status, in which case we would likely have to obtain MBR Authority and sell competitively in the market. If this were to happen, in all likelihood our QFs would not be competitive in the market place.

40wholesale sales (that is, sales for resale) of renewable electricity, capacity, and ancillary services from our QFs with a net generating capacity that does not exceed 20 megawatts or that is an “eligible” facility as defined by section 3(17)(E) of the Federal Power Act without (a) obtaining authorization by FERC pursuant to the Federal Power Act to sell electric energy, capacity and/or ancillary services at market-based rates, (b) acceptance by FERC of a tariff providing for such sales, and (c) granting by FERC of such regulatory waivers and blanket authorizations as are customarily granted by FERC to holders of market-based rate authority, including blanket authorization under section 204 of the Federal Power Act to issue securities and assume liabilities (“MBR Authority”) or any other approval from the U.S. Federal Energy Regulatory Commission (“FERC”).

If this were to happen, in all likelihood our QFs would not be competitive in the market place.

We currently do not intend to develop, construct or operate electric generating facilities that would require us to apply for and receive MBR Authority from FERC. Nevertheless, if we were to do so, 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 own, directly or indirectly, 10% 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 for additional facilities, were we or such affiliate required to obtain such authority, would require an evaluation of the energy assets owned directly or indirectly by us and each of our affiliates, satisfying market-power limitations established by FERC. If our affiliates invest heavily in generating or other electric facilities in a particular geographic market, their market presence could make it difficult for us or our affiliates to obtain and maintain such MBR Authority, or to secure FERC authorization to acquire additional generating facilities, in that market.

Our market-based sales are subject to certain market behavior rules established by FERC, and if any of our Biogas Conversion Projects that generate Renewable Power are deemed to have violated such rules, we will be subject to potential disgorgement of profits associated with the violation, penalties, refunds of unlawfully collected amounts with interest, and, if a facility obtains MBR Authority, suspension or revocation of such MBR Authority. If such projects that had MBR Authority were later to lose their MBR Authority, they would be required to obtain 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 maintaining MBR Authority, if any, that generate Renewable Power.

The regulatory environment for electric generation has undergone significant changes in the last several years due to federal and state 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 biogas conversion project site owners and operators are also subject to extensive federal, state and local regulations and policies, including permitting requirements. Any failure on their part to comply with any laws, regulations, rules or permits, applicable to them may also adversely affect our business, investments and results of operations.

The operations of biogas conversion project site owners and operators are also subject to stringent and complex governmental regulations and policies at the federal, state and local level in the United States. Many complex laws, rules, orders and interpretations govern environmental protection, health, safety, land use, zoning, transportation and related matters. At times, such governmental regulations and policies may require biogas conversion project site owners and operators to curtail their operations or close sites temporarily or permanently, which may adversely impact our business, investments and results of operations.

Certain permits are required to build, operate and expand sites owned by biogas conversion project site owners and operators, and such permits have become more difficult and expensive to obtain and maintain. Permits may often take years to obtain as a result of numerous hearing and compliance requirements with regard to zoning, environmental and other regulations and are commonly subject to resistance from citizen or other groups and other political pressures, including allegations by such persons that a site is in violation of any applicable permits, laws or regulations. Failure by project site owners and operators to obtain or maintain any required permit to operate its site would adversely affect our production of Renewable Power, RNG and generation of the associated Environmental Attributes, as applicable.

owners and operators to obtain or maintain any required permit to operate its site would adversely affect our production of Renewable Power, RNG and generation of the associated Environmental Attributes, as applicable.

A failure by biogas conversion project site owners and operators to comply with extensive federal, state and local regulations and policies, including permitting requirements, may result in the suspension or cessation of site operations, which would reduce or halt Renewable Power or RNG production and generation of the associated Environmental Attributes. Any such disruption could also damage the reputation of our brand. In the event our production of Renewable Power or RNG is disrupted, we may fail to meet the contractual obligations to some of our counterparties to deliver Renewable Power, RNG and the associated Environmental Attributes, in which case we would be subject to financial damage and/or penalty claims from these counterparties.

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.

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 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.

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 ofon 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.44

The Company may incur contractual obligations from the indemnification of third parties if tax authorities challenge the amount or availability of ITCs or related tax benefits that the Company is obligated to provide to such third parties under such contractual arrangements.

42The Company from time-to-time enters into arrangements with third parties that acquire tax credits, including ITCs, from the Company where tax credits and related tax benefits represent a material portion of the economic benefit of the arrangement to such other party. In certain circumstances, as is customary in the industry, the Company has guaranteed and may have to guarantee the economic benefit of such tax credits and other tax benefits to such party. A reduction in expected tax credits or tax benefits resulting from successful challenges by the IRS could result in an obligation under the Company’s contractual arrangements that could have a material impact on the Company’s financial condition, results of operations and liquidity.

The Company from time-to-time enters into arrangements with third parties that acquire tax credits, including ITCs, from, the Company where tax credits and related tax benefits represent a material portion of the economic benefit of the arrangement to such other party. In certain circumstances, as is customary in the industry, the Company has guaranteed and may have to guarantee the economic benefit of such tax credits and other tax benefits to such party. A reduction in expected tax credits or tax benefits resulting from successful challenges by the IRS could result in an obligation under the Company’s contractual arrangements that could have a material impact on the Company’s financial condition, results of operations and liquidity.

We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that will increase both our costs and the risk of noncompliance.

We are subject to rules and regulations by various governing bodies, including, for example, the SEC, which are charged with the protection of investors and the oversight of companies whose securities are publicly traded, and to new and evolving regulatory measures under applicable law. Our efforts to comply with new and changing laws and regulations ~~has~~have resulted in increased general and administrative expenses.

Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to our disclosure and governance practices. If we fail to address and comply with these regulations and any subsequent changes, we may be subject to penalty and our business may be harmed.

On July 12, 2023, the EPA issued final rule 88 Fed. Reg. 44468 (July 12, 2023) to, in part, implement biogas regulatory reform to the EPA’s Renewable Fuel Standard Program (“RFS”) (the “Biogas Regulatory Reform Rule” or “BRRR”). BRRR significantly changed the method by which RINs are generated from biogas feedstock and how market participants are required to administer RINs. BRRR required all parties in the chain of title to biogas, renewable natural gas, and RINs to register with the EPA by January 1, 2025.

The Company timely completed and received approval of its required registrations under BRRR. As part of this registration process, with respect to ~~fueling~~Fueling ~~stations~~Stations, the Company registered as RNG RIN separator for stations that accounted for approximately 57% of the Company’s CNG dispensing capacity. Wherever the Company is not registered as the RNG RIN separator, it will rely on the owner/operator of the ~~fueling~~Fueling ~~station~~Station to perform the role as RNG RIN separator (i.e., separating the RINs and transferring them to the Company for monetization). There can be no assurance that these owners/operators will timely provide the necessary administrative services and transactional data required for the separation and transfer of RINs from these stations. If we are unable to receive RINs from stations representing a material proportion of our dispensing capacity, it would have a material adverse effect on our financial results.

Risks Related to Our Indebtedness

Our level of indebtedness and preferred stock redemption obligations 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. We may be unable to obtain additional financing to fund our operations or growth.

As of December 31, 2024, our total indebtedness was $307.5 million, excluding deferred financing costs. Additionally, we have redeemable preferred non-controlling interests outstanding of $130.0 million.45

As of December 31, 2025, our total indebtedness was $361.3 million, excluding deferred financing costs. Additionally, we have redeemable preferred non-controlling interests outstanding of $130.0 million.

Our substantial indebtedness and preferred units redemption obligations could have important consequences, including, for example:

•being required to accept then-prevailing market terms in connection with any required refinancing of such indebtedness or redemption obligations, 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 and dividend obligations require us to dedicate a substantial portion of our cash flow to pay principal and interest on our debt and dividends on our preferred units, thereby reducing the funds available to us and our ability to borrow to operate and grow our business;

•increase in interest rates on our existing debt facilities or a reduction in the supply of project debt financing could reduce our ability to construct and operate new RNG projects or ~~fueling~~Fueling ~~stations~~Stations;

•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 or mandatory redeemable preferred units.

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 or with respect to our preferred units, we may be required to refinance all or part of our existing debt and preferred units, 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 and dividend rates and changes in debt and preferred equity covenants may reduce the amounts that we can borrow or otherwise finance, reduce our cash flows and increase the equity investment we may be required to make to complete construction of our Biogas Conversion Projects and Fueling Stations. 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 and preferred unit obligations, we could be in default under our lending agreements and preferred unit designations 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.

Our existing credit facilities contain financial covenants and our credit facilities and preferred stock designations contain other restrictive covenants that limit our ability to return capital to equity holders 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 or material breach which, if not cured or waived, may entitle the related lenders or preferred unit holders to higher interest or dividend payment to demand repayment or enforce their security interests (in the case of indebtedness) and other remedies, 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. Further, in certain circumstances following a failure to timely redeem our preferred stock, holders of such preferred stock will have certain rights and remedies.

For example, upon written notice from NextEra at any time after November 29, 2025, we would be required to redeem the Series A preferred units. In the event we do not redeem the Series A preferred units when requested, Nextera will have the following rights and remedies: (1) NextEra’s affiliate may extend the RNG Marketing Agreement by 12 months; or (2) the dividend rate would increase depending on the length of time the Series A preferred units remain unredeemed to up to 20% per annum, and if more than $25,000,000 preferred equity is outstanding for more than six months after November 29, 2025, NextEra may appoint a director to our Board of Directors; or (3) NextEra may convert the Series A preferred equity into common equity of the OPAL Fuels LLC at a conversion price at a 20% to 30% discount to their value (the discount is 20% during the first 12 months after November 29, 2025, 25% for the next 12 months thereafter and 30% thereafter). For more information related to our obligation to redeem the Series A preferred units, please refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.

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 not be able 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 or projects 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.

Risks Related to Ownership of Our Class A Common Stock

44Future sales and issuances of our Class A common stock could result in additional dilution of the percentage ownership of our stockholders and could cause our share price to fall.

~~Future~~We ~~sales~~expect ~~and~~that ~~issuances~~significant additional capital will be needed in the future to pursue our growth plan. To raise capital, we may sell shares of our Class A common stock, ~~could~~convertible ~~result~~securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we or our subsidiaries issue additional ~~dilution~~equity ofsecurities, ~~the~~investors ~~percentage~~may ~~ownership~~be ofmaterially diluted by subsequent sales. Such sales may also result in material dilution to our ~~shareholders~~existing stockholders, and new investors could ~~cause~~gain ~~our~~rights, ~~share~~preferences, ~~price~~and privileges senior to ~~fall~~existing holders of our Class A common stock.

We expect that significant additional capital will be needed in the future to pursue our growth plan. To raise capital, we may sell shares of our Class A common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we or our subsidiaries issue additional equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing shareholders, and new investors could gain rights, preferences, and privileges senior to existing holders of our Class A common stock.

Future sales of a substantial number of shares of our Class A common stock, or the perception in the market that the holders of a large number of shares of Class A common stock intend to sell shares, could reduce the market price of our Class A common stock.

Sales of a substantial number of shares of our Class A common stock in the public market, including the resale of the shares of held by our stockholders, could occur at any time. These sales, or the perception in the market that the holders of a large number of shares of Class A common stock intend to sell shares, could reduce the market price of our Class A common stock.

Pursuant to that certain Investor Rights Agreement, dated July 21, 2022, by and among OPAL Fuels Inc., each of the sellers named therein, ArcLight CTC Holdings II, L.P. and its principals, those stockholders are entitled to have the registration statement under the Securities Act kept effective for a prolonged period of time such that registered resales of their shares of Class A common stock can be made. We originally registered for resale up to 163,676,735 shares of our Class A common stock pursuant to our registration statement on Form S-3 filed under the Securities Act (File No. 333-266757), which was declared effective on August 10, 2023.

The resale, or expected or potential resale, of a substantial number of shares of our Class A common stock in the public market could adversely affect the market price for our Class A common stock and make it more difficult for you to sell your holdings at times and prices that you determine are appropriate. Furthermore, we expect that, because a large number of shares were registered pursuant to such registration statement, the selling holders thereunder will continue to offer the securities covered thereby for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to the registration statement may continue for an extended period of time.

We are an “emerging growth company,” and our election to comply with the reduced disclosure requirements as a public company may make our Class A common stock less attractive to investors.

For so long as we remain an “emerging growth company,” as defined in the JOBS Act, we may take advantage of certain exemptions from various requirements that are applicable to public companies that are not “emerging growth companies,” including not being required to comply with the independent auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, being required to provide fewer years of audited financial statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We may lose our emerging growth company status and become subject to the SEC’s internal control over financial reporting auditor attestation requirements. If we are unable to certify the effectiveness of our internal controls, or if our internal controls have a material weakness, we could be subject to regulatory scrutiny and a loss of confidence by stockholders, which could harm our business and adversely affect the market price of the common stock. We will cease to be an “emerging growth company” upon the earliest to occur of: (i) the last day of the fiscal year in which we have more than $1.235 billion in annual revenue; (ii) the date we qualify as a large accelerated filer, with at least $700.0 million of equity securities held by non-affiliates; (iii) the date on which we have, in any three-year period, issued more than $1.0 billion in non-convertible debt securities; and (iv) December 31, 2026 (the last day of the fiscal year following the fifth anniversary of ArcLight becoming a public company).

45internal controls have a material weakness, we could be subject to regulatory scrutiny and a loss of confidence by stockholders, which could harm our business and adversely affect the market price of the common stock. We will cease to be an “emerging growth company” upon the earliest to occur of: (i) the last day of the fiscal year in which we have more than $1.235 billion in annual revenue; (ii) the date we qualify as a large accelerated filer, with at least $700.0 million of equity securities held by non-affiliates; (iii) the date on which we have, in any three-year period, issued more than $1.0 billion in non-convertible debt securities; and (iv) December 31, 2026 (the last day of the fiscal year following the fifth anniversary of ArcLight becoming a public company).

As an emerging growth company, we may choose to take advantage of some but not all of these reduced reporting burdens. Accordingly, the information we provide to our stockholders may be different than the information you receive from other public companies in which you hold stock. In addition, the JOBS Act also provides that an “emerging growth company” can take advantage of an extended transition period for complying with new or revised accounting standards. We have elected to take advantage of this extended transition period under the JOBS Act. As a result, our operating results and financial statements may not be comparable to the operating results and financial statements of other companies who have adopted the new or revised accounting standards. It is possible that some investors will find our Class A common stock less attractive as a result, which may result in a less active trading market for our Class A common stock and higher volatility in our stock price.

Our current majority stockholder has control over all stockholder decisions because it controls a substantial majority of our voting power through “high vote” voting stock. Such majority stockholder, and the persons controlling such majority stockholder, including Fortistar and Mr. Mark Comora, our Chairman of the board of directors, may have potential conflicts of interest in connection with existing or proposed business relationships and decisions impacting us and, even in situations where it does not have a conflict of interest, its interests in such matters may be different than the other stockholders.

The dual-class structure of our common stock has the effect of concentrating voting control with Mr. Mark Comora who, through his control of OPAL Holdco and Hillman, beneficially owns in the aggregate a substantial majority of the voting power of our capital stock on most issues of corporate governance. Mr. Mark Comora beneficially owns ~~145~~148,336,349 shares of OPAL, comprising 8384.71% of our outstanding common stock as of March 1412, ~~2025~~2026, assuming conversion of all shares of Class B and Class D common stock into shares of Class A common stock. All of these shares (with the exception of 880,600 shares of Class A common stock purchased by Fortistar in the PIPE Investment, 3,000,000 shares of Class A common stock underlying warrants beneficially owned by Fortistar, and 56,712 shares of Class A common stock held directly by Mr. Comora) are Class B common stock, or are Class D common stock which have no economic rights but are entitled to five votes per share, giving Mr. Mark Comora control over 9389.95% of our voting power. OPAL Holdco and Hillman are controlled, indirectly, by Mr. Mark Comora through entities affiliated with Mr. Mark Comora, including Fortistar and certain of its other affiliates. Mr. Mark Comora is the Chairman of our board of directors.

Accordingly, Mr. Mark Comora is able to control most matters submitted to our stockholders for approval. This concentrated control will limit or preclude your ability to influence corporate matters for the foreseeable future, including the election of directors, amendments to our certificate of incorporation or bylaws, and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval. This may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that you may feel are in your best interest as one of our stockholders. More specifically, Mr. Mark Comora has the ability to control our management and our major strategic investments and decisions as a result of his ability to control the election or, in some cases, the replacement of our directors. In the event of the death of Mr. Mark Comora, control of the shares of common stock controlled by Mr. Mark Comora will be transferred to the persons or entities that he has designated. In his position as the Chairman of our board, Mr. Mark Comora owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of our stockholders. As a beneficial owner of our common stock, even as a controlling stockholder Mr. Mark Comora is entitled to vote the shares he controls, in his own interests, which may not always be in the interests of our stockholders generally.

Future transfers by holders of Class C common stock and Class D common stock, which carry five votes per share, will generally result in those shares converting to Class A common stock and Class B common stock, respectively, which carry only one vote per share, unless in each case made to a Qualified Stockholder (as defined in the Second A&R LLC Agreement). The conversion of Class D common stock to Class B common stock and the conversion of Class C common stock to Class A common stock, as the case may be, means that no third party stockholders can leverage the high vote to offset the voting power held by the OPAL Holdco and Hillman.

In addition, Fortistar and certain of its affiliates (other than our subsidiaries), which are controlled by Mr. Mark Comora (who also controls OPAL Holdco and Hillman), manage numerous investment vehicles and separately managed accounts. Fortistar and these affiliates may compete with us for acquisition and other business opportunities, which may present conflicts of interest for these persons. If these entities or persons decide to pursue any such opportunity, we may be precluded from procuring such opportunities. In addition, investment ideas generated within Fortistar and these affiliates may be suitable both for us and for current or future investment vehicles managed by Fortistar and these affiliates and may be directed to such investment vehicles rather than to us. Neither Fortistar nor members of our management team who are also members of the management of Fortistar or of any of these affiliates, including Mr. Mark Comora and Mr. Nadeem Nisar (who serves on our board), have any obligation to present us with any potential business opportunity of which they become aware, unless, (i) such opportunity is expressly offered to such person solely in his or her capacity as a one of our directors or officers, (ii) such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and (iii) the director or officer is permitted to refer that opportunity to us without violating another legal obligation. Fortistar and/or members of our management team, such as Mr. Mark Comora or Mr. Nisar in their capacities as management of Fortistar or in their other endeavors, may be required to present potential business opportunities to the related entities described above, current or future affiliates of Fortistar, or third parties, before 48

they present such opportunities to us. The personal and financial interests of such persons described above may be in conflict with the interests of ours and influence their motivation in identifying and selecting our business opportunities, their support or lack thereof for pursuing such business opportunities and our operations.

The existence of a family relationship between Mr. Mark Comora, as our Chairman of our board, and Mr. Adam Comora, as our Co-Chief Executive Officer, may result in a conflict of interest on the part of such persons between what they, in their capacity as Chairman or Co-Chief Executive Officer, respectively, may believe is in our best interests and the interests of our stockholders in connection with a decision to be made by us through our board, standing committees thereof, and management and what he may believe is best for himself or his family members in connection with the same decision.

Mr. Mark Comora and Mr. Adam Comora are father and son. In his position as the Chairman of our board, Mr. Mark Comora owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of the stockholders. And in his position as our Co-Chief Executive Officer, Mr. Adam Comora owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of the stockholders. Nevertheless, the existence of this family relationship may result in a conflict of interest on the part of such persons between what he may believe is in our best interests and the best interests of our stockholders and what he may believe is best for himself or his family members in connection with a business opportunity or other matter to be decided by OPAL through its board, standing committees thereof, and management. Moreover, even if such family relationship does not create an actual conflict, the perception of a conflict in the press or the financial or business community generally could create negative publicity or other reaction with respect to the business opportunity or other matters to be decided by us through our board, standing committees thereof, and management, which could adversely affect the business generated by us and our relationships with its existing customers and other counterparties, impact the behavior of third party participants or other persons in the proposed business opportunity or other matter to be decided, otherwise negatively impact our business prospects related to such matter, or negatively impact the trading market for our securities.

We are a controlled company, and thus not subject to all of the corporate governance rules of Nasdaq. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

We are considered a “controlled company” under the rules of Nasdaq. Controlled companies are exempt from the Nasdaq corporate governance rules requiring that listed companies have (i) a majority of the board of directors consist of “independent” directors under the listing standards of Nasdaq, (ii) a nominating/corporate governance committee composed entirely of independent directors and a written nominating/corporate governance committee charter meeting the Nasdaq requirements and (iii) a compensation committee composed entirely of independent directors and a written compensation committee charter meeting the requirements of Nasdaq. We expect to take advantage of some or all of the exemptions described above for so long as we are a controlled company. If we use some or all of these exemptions, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of Nasdaq.

The dual-class structure of our common stock may adversely affect the trading market for the shares of Class A common stock.

We cannot predict whether our dual class structure, which affords the shares of Class A common stock and Class B common stock one vote per share while affording the shares of Class C common stock and Class D common stock with five votes per share, combined with our concentrated voting control by OPAL Holdco due to its ownership of shares of Class D common stock, will result in a lower or more volatile market price of the shares of Class A common stock or in adverse publicity or other adverse consequences. For example, certain index providers have announced restrictions on including companies with multiple-class share structures in certain of their indexes. Under any such announced policies or future policies, our dual class capital structure could make us ineligible for inclusion in certain indices, and as a result, mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track those indices will not be investing in our stock. It is unclear what effect, if any, these policies will have on the valuations of publicly traded companies excluded from such indices, but it is possible that they may depress valuations as compared to similar companies that are included. As a result, the market price of shares of Class A common stock could be adversely affected.

There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq.

Our shares of Class A common stock are listed on Nasdaq under the symbol “OPAL”. If Nasdaq delists our securities from trading on its exchange for failure to meet the listing standards, we and our stockholders could face significant negative consequences. The consequences of failing to meet the listing requirements include:

•limited availability of market quotations 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;

•possible reduction in the level of trading activity in the secondary trading market for shares of the Class A common stock;

•a limited amount of analyst coverage; and

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

Because there are no current plans to pay cash dividends on shares of common stock for the foreseeable future, you may not receive any return on investment unless you sell your shares of 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 our board, who 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 us to our ~~its~~ stockholders or by our subsidiaries to us and such other factors our board may deem relevant. In addition, our ability to pay dividends is limited by covenants of any indebtedness we incur. As a result, you may not receive any return on an investment in the shares of Class A common stock unless you sell your shares of Class A common stock for a price greater than that which you paid for it.

Anti-takeover provisions are contained in our certificate of incorporation that could delay or prevent a change of control.

Certain provisions of our certificate of incorporation 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 of ours might consider is in its best interest, including those attempts that might result in a premium over the market price for the shares of our Class A common stock.

These provisions, among other things:

•authorize our 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 shares of common stock;

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

•eliminate the ability of stockholders to fill vacancies on our board;

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

•permit our board to establish the number of directors;

•provide that our board is expressly authorized to make, alter or repeal our bylaws; and

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

These anti-takeover provisions, together with the control of the voting power of by OPAL Holdco, could make it more difficult for a third-party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. As a result, our 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 us to take other corporate actions you desire.

The trading price of the Class A common stock has been, and is likely to continue to be, volatile and could fluctuate in response to a number of factors, many of which are beyond our control.

The trading price of the Class A common stock may fluctuate significantly in response to a number of factors, many of which are beyond our control. For instance, if our financial results are below the expectations of securities analysts and investors, the market price of the Class A common stock could decrease, perhaps significantly. Factors that may affect the market price of the Class A common stock include changes in market prices of oil, natural gas and natural gas liquids; announcements relating to significant corporate transactions; fluctuations in our quarterly and annual financial results; operating and stock price performance of companies that investors deem comparable to us; and changes in government regulation or proposals relating to us, including as a result of increased and/or new tariffs on equipment supply and raw materials. In addition, the U.S. securities markets have experienced significant price and volume fluctuations, and these fluctuations often have been unrelated to the operating performance of companies in these markets. Any volatility of, or a significant decrease in, the market price of the Class A common stock could also negatively affect our ability to make acquisitions using Class A common stock. Further, if we were to be the object of securities class action litigation as a result of volatility in the Class A common stock price or for other reasons, it could result in substantial costs and diversion of our management’s attention and resources, which could negatively affect our financial results.

In addition, uncertainty surrounding potential tariff increases on imported products and possible retaliatory measures by other countries could negatively impact our business. On ~~February~~At 1,this ~~2025~~time, it is unclear the ~~U.S.~~extent ~~government~~to ~~proposed~~which any tariffs ofwill upapply to ~~25%~~imports onof ~~imports~~equipment ~~from~~and ~~certain~~machinery ~~countries,~~upon ~~including~~which ~~Mexico~~our ~~and~~business ~~Canada,~~is ~~and~~reliant. ~~implemented~~Any ~~additional~~new or increased tariffs, ontrade ~~imports~~sanctions, ~~from~~or ~~China~~changes in U.

At this time, it is unclear whether these tariffs will apply to imports of equipment and machinery upon which our business is reliable. Any new or increased tariffs, trade sanctions, or changes in U.S. trade policy could lead to higher operational costs. If we are unable to pass these additional costs to our customers and/or effectively manage higher operational expenses, our financial performance could be adversely affected.

While we continue to assess the potential impact of these proposed tariffs and explore mitigation strategies, we do not currently anticipate a material adverse effect on our cost of goods sold or gross profit. This expectation assumes that the financial burden of increased tariffs will be absorbed primarily by market adjustments.

A credit ratings downgrade or other negative action by a credit rating organization could adversely affect the trading price of the shares of our Class A common stock.

Credit rating agencies continually revise their ratings for companies they follow. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future.

In addition, developments in our business and operations could lead to a ratings downgrade for us or our subsidiaries. Any such fluctuation in our or our subsidiaries’ ratings may impact our ability to access debt markets in the future or increase our cost of future debt, which could have a material adverse effect on our operations and financial condition, which in return may adversely affect the trading price of shares of our Class A common stock.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Company; (ii) any action, suit or proceeding (including any class action) asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of the Company to the Company or the Company’s stockholders; (iii) any action, suit or proceeding (including any class action) asserting a claim against the Company or any current or former director, officer, other employee, agent or stockholder of the Company arising out of or pursuant to any provision of the General Corporation Law, this Certificate of Incorporation or the By-laws (as each may be amended from time to time); (iv) any action, suit or proceeding (including any class action) to interpret, apply, enforce or determine the validity of this Certificate of Incorporation or the By-laws (including any right, obligation or remedy thereunder); (v) any action, suit or proceeding as to which the General Corporation Law confers jurisdiction to the Court of Chancery of the State of Delaware; or (vi) any action asserting a claim against the Company or any director, officer or other employee of the Company governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants.

The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court finds the choice of forum provision contained in our 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 materially and adversely affect our business, financial condition, and results of operations.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. In addition, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws. We note that there is uncertainty as to whether a court would enforce the choice of forum provision with respect to claims under the federal securities laws, and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

We rely on information technology and data to operate our business and develop, market, and deliver our products and services to our customers. We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to critical computer networks, third party hosted services, communications systems, hardware, software, and our confidential, personal, proprietary, and sensitive data (collectively, “Information Assets”). Accordingly, we maintain certain risk assessment processes intended to identify cybersecurity threats. We have implemented an information technology security policy, which includes cybersecurity vulnerability management designed to protect the confidentiality, integrity, and availability of our Information Assets and mitigate harm to our business.

We engage in processes designed to identify such threats by, among other things, monitoring the threat environment using manual and automated tools. We subscribe to reports and services that identify cybersecurity threats, analyze reports of threats and conduct vulnerability assessments to identify vulnerabilities.

Depending on the environment, we implement and maintain various technical, physical and organizational measures designed to manage and mitigate material risks from cybersecurity threats to our Information Assets. We work with third parties, including cybersecurity software providers and managed cybersecurity service providers, to identify and assess cybersecurity risks and conduct penetration testing.

Governance

Our cybersecurity risk assessment and management processes are implemented and maintained by a third-party service provider reporting to the Company's management. Management is also responsible for integrating cybersecurity considerations into our overall risk management strategy, communicating key priorities to employees, approving budgets, helping to prepare for cybersecurity incidents, approving cybersecurity processes, reviewing security assessments and making required disclosures. Management participates in cybersecurity incident response efforts by being a member of the incident response team and helping direct our response to cybersecurity incidents.

Our board of directors addresses our cybersecurity risk management as part of its general oversight function. The Audit Committee of the board of directors is responsible for overseeing our cybersecurity risk management processes, including oversight and mitigation of risks from cybersecurity threats.

ITEM 2. PROPERTIES

We do not own any real property. Our corporate headquarters are located in White Plains, New York, where we occupy approximately 13,600 square feet of shared office space with an affiliate of Fortistar pursuant to an Administrative Services Agreement. In addition, we lease office and maintenance facilities in Oronoco, Minnesota and Rancho Cucamonga, California. Our interests in our RNG and Renewable Power projects are our only material properties. See Item 1. Business — Our projects for additional information.

ITEM 3. LEGAL PROCEEDINGS

From time to time, we are involved in various legal proceedings, lawsuits and claims incidental to the conduct of our business, some of which may be material. Our businesses are also subject to extensive regulation, which may result in regulatory proceedings against us. We do not believe that the outcome of any of our current legal proceedings will have a material adverse impact on our business, financial condition and results of operations.

Central Valley Project

In September 2021, an indirect subsidiary of the Company, MD Digester, LLC (“MD”), entered into a fixed-price Engineering, Procurement and Construction Contract (an “EPC Contract”) with VEC Partners, Inc. d/b/a CEI Builders (“CEI”) for the design and construction of a turn-key renewable natural gas production facility using dairy cow manure as feedstock in California’s Central Valley. In December 2021, a second indirect subsidiary of the Company, VS Digester, LLC (“VS”) entered into a nearly identical EPC Contract (collectively, the "EPC Contracts") with CEI for the design and construction of a second facility, also in California’s Central Valley. CEI’s performance under both of the EPC Contracts is fully bonded by licensed sureties.

CEI has submitted a series of change order requests seeking to increase the EPC Contract Price by approximately $14 million, per project, primarily due to: (1) modifications to CEI’s design drawings which are required to meet its contracted performance guaranties, and (2) a default by one of CEI’s major equipment manufacturers. The Company disputes the vast majority of the change order requests.

In January 2024, the Company filed a civil lawsuit captioned, MD Digester, LLC. et. al. vs. VEC Partners, Inc. et. al.; with the California Superior Court, County of San Joaquin; Action No. STK- CV-UCC-2024-0000185 and commenced a related arbitration proceeding in order to obtain a formal determination on the claims; AAA Case No. 01-24-0000-0775. The Superior Court Action has been stayed, pending the conclusion of the arbitration. In the meantime, the AAA has empaneled three experienced arbitrators and has set the hearing date for the matter, currently ~~schedule~~scheduled in May 2026.

The EPC Agreement requires that CEI, continue working during the course of the litigation and related arbitration proceedings; however, CEI effectively stopped working. ~~Between~~On ~~May~~June ~~and~~26, ~~August~~ 2024, MD issued a ~~series~~Notice of ~~Notices of~~ Default and ~~Demands~~Demand to Cure to CEI. CEI failed to ~~cure~~do so, and on July 30, 2024, MD terminated CEI for default. MD notified CEI’s performance bond surety, Atlantic Specialty Insurance Company of the termination and demanded that it perform under the bond. Atlantic has denied the claim.

On July 11, 2024, VS issued a Notice of Default and Demand to Cure, advising CEI of its defaults and giving it an opportunity to cure. CEI failed to do so, and on August 27, 2024, VS terminated CEI for default. VS has notified CEI’s bond surety, also Atlantic, of the second termination and demanded that it perform under the performance bond. The surety has denied the claim.

As a result of CEI’s default and Atlantic’s denial of the claims, MD and VS have amended their claims in the AAA arbitration to include breach of contract claims against CEI and breach of performance bond claims against Atlantic (who was formally joined into the arbitration on November 20, 2024) in the AAA Arbitration with CEI.

CEI has since recorded mechanic’s liens against each of the projects for $4.9 million (MD) and $2 million (VS), and recently filed actions with the Stanislaus and San Joaquin County Superior Courts, respectively, to enforce their liens. It is expected that these claims will be stayed and consolidated with the pending arbitration proceeding.

In addition to the above-referenced action and arbitration, several of CEI’s subcontractors have recorded mechanic’s liens against the MD and VS projects, which the Company is obligated to defend and indemnify the dairy owners from and against. Several of liens were untimely and have been released.

The Company believes its claims against CEI (and the surety where bond claims are denied) have substantial merit, and intends to prosecute the claims vigorously. However, due to the incipient stage of the litigation and related arbitration, the recency of the termination, and the ongoing status of the proceedings and discussions with the bond surety, as well as the uncertainties involved in all litigation and arbitration, the Company does not believe it is feasible at this time to assess the likely outcome of the litigation and related arbitration, the timing of its resolution, or its ultimate impact, if any, on the Central Valley projects or the Company's business, financial condition or results of operations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In this Management's Discussion and Analysis of Financial Condition and Results of Operations section, references to "OPAL," "we," "us," "our," and the "Company" refer to OPAL Fuels Inc. and its consolidated subsidiaries. The following discussion and analysis should be read in conjunction with our consolidated financial statements and related notes set forth in Part II, Item 8 - "Financial Statements and Supplementary Data" and the risk factors identified in Part I, Item 1A - "Risk Factors" of this Annual Report. For further discussion regarding our results of operations for the year ended December 31, 2023 as compared to the year ended December 31, 2022, refer to Part II, Item 7 - "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC on March 15, 2024. In addition to historical information, this discussion and analysis includes certain forward-looking statements which reflect our current expectations. The Company's actual results may materially differ from these forward-looking statements.

Overview

The Company is a vertically integrated leader in the capture and conversion of biogas into low carbon intensity Renewable Power and RNG. OPAL Fuels is also a leader in the marketing and distribution of RNG to heavy duty trucking and other hard to de-carbonize industrial sectors. RNG is chemically identical to the natural gas used for cooking, heating homes and fueling natural gas engines, with one significant difference: RNG is produced by recycling methane emissions created by decaying organic waste as opposed to natural gas which is a fossil fuel pumped from the ground. We have participated in the biogas-to-energy industry for over 20 years.

Biogas is generated by microbes as they break down organic matter in the absence of oxygen, and comprised of non-fossil waste gas, with high concentrations of methane, which is the primary component of RNG and the source for combustion utilized by Renewable Power plants to generate electricity. Biogas can not only be collected and processed to remove impurities for use as RNG (a form of high-Btu fuel) and injected into existing natural gas pipelines as it is fully interchangeable with fossil natural gas, but partially treated biogas can be used directly in heating applications (as a form of medium-Btu fuel) or in the production of Renewable Power. Our principal sources of biogas are (i) ~~landfill gas~~LFG, which is produced by the decomposition of organic waste at landfills, and (ii) dairy manure, which is processed through anaerobic digesters to produce the biogas.

As of December 31, 2024, we owned and operated 26 projects, 11 of which are RNG projects and 15 of which are Renewable Power Projects. As of that date, our RNG projects in operation had a design capacity of 8.8 million MMBtus per year and our Renewable Power Projects in operation had a nameplate capacity of 105.8 MW per hour. In addition to these projects in operation, we are actively pursuing expansion of our RNG-generating capacity and, accordingly, have a portfolio of RNG projects in construction or in development, with six of our current Renewable Power Projects being considered candidates for conversion to RNG projects in the foreseeable future.

Recent Developments

~~Wasatch~~On ~~Resource~~March ~~Recovery~~6, ~~Facility~~2026, OPAL Fuels LLC entered into a subscription agreement with Preferred Fuels LLC (“Preferred Fuels”), an affiliate of Fortistar, pursuant to which Preferred Fuels committed to purchase up to $180.0 million of Series A preferred units in multiple closings. At the initial closing on March 6, 2026, the investor purchased 1.2 million Series A preferred units for aggregate proceeds of $120.0 million. OPAL Fuels may, in its sole discretion, require the investor to fund up to an additional $60.0 million within one year of the initial closing, subject to the terms of the subscription agreement.

53In addition, subsequent to December 31, 2025, the Company drew approximately $128.4 million under its term loan facility pursuant to its existing credit agreement. A portion of the proceeds from the borrowing was used to repay approximately $20.0 million outstanding under the revolving loan facility.

In connection with the acquisition, Fortistar Services 2 LLC and OPAL Fuels LLC entered into an amendment to its existing Administrative Services Agreement, pursuant to which OPAL Fuels will provide certain services to Wasatch RNG in exchange for certain agreed upon fees and expense reimbursements. These services include oversight of the plan to improve the operations and productivity of the Project.

Additionally, Wasatch RNG and OPAL Fuels entered into an Option Agreement, pursuant to which Wasatch RNG granted an option to OPAL Fuels to purchase the Alpro Interest. The exercise period of the option commenced upon closing of the acquisition and will terminate on the third anniversary of the closing of the acquisition, or ninety days following a change of control of OPAL Fuels. The exercise price of the option would be determined such that Wasatch RNG would earn an internal rate of return on its invested capital of 10% percent per year if the option is exercised in the first year, 15% per year if exercised in the second year, and 20% per year if exercised in the third year.

OPAL Term Loan Amendment

On March 3, 2025, OPAL Fuels Intermediate HoldCo LLC, as the borrower (the “Borrower”), certain subsidiaries of the Borrower, as guarantors (the “Guarantors”), the lenders and issuers of letters of credit party thereto and Bank of America, N.A. as the administrative agent (the “Administrative Agent”) entered into that certain Amendment No. 1 to Credit and Guarantee Agreement (the “Credit Agreement Amendment”), with respect to that certain Credit and Guarantee Agreement (the “Credit Agreement”) dated September 1, 2023, by and among the Borrower, the Administrative Agent, the financial institutions from time to time parties thereto as lenders and as issuers of letters of credit, and the other agents and persons from time to time party thereto (as amended, restated, amended and restated, supplemented or otherwise modified and in effect from time to time).

The Credit Agreement Amendment makes certain changes to the applicability of certain financial covenants and modifies other covenants to clarify the use of loan proceeds. Additionally, the Credit Agreement Amendment permits the organizational restructuring of the Guarantors in a manner designed to facilitate the sale of federal investment tax credits and the ability to raise additional future capital.

The Credit Agreement Amendment also eases the conditions precedent to making new Projects eligible for borrowing under the Credit Agreement, extends the availability period for delay draw term loans under the Credit Agreement through March 5, 2026, and extends the commencement of repayment of such term loans until March 31, 2026.

In connection with the Credit Agreement Amendment, the Borrower paid the Administrative Agent, for the account of each lender, a one-time nonrefundable fee of $1,250,000.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") and the rules and regulations of the SEC, which apply to interim financial statements. The preparation of those financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues, expenses and warrants and related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions and conditions.

Critical accounting policies are those that reflect significant judgments of uncertainties and potentially result in materially different results under different assumptions and conditions. We have described below what we believe are our most critical accounting policies, because they generally involve a comparatively higher degree of judgment in their application. For a detailed description of all our accounting policies, see Note 2. Summary of Significant Accounting Policies, to our consolidated financial statements included herein.

Revenue Recognition

Renewable Power

We sell Renewable Power produced from LFG-fueled power plants to utility companies through our PPAs. Revenue is recognized based on contract specified rates per MWh when delivered to the customer, as this considered to be completion of the performance obligation. Certain PPAs contain a lease element which we account for as operating lease revenue on a straight-line basis over the lease term. The Company utilizes commodity swap contracts to hedge against the unfavorable price fluctuations in market prices of electricity. The Company does not apply hedge accounting to these contracts. As

such, unrealized and realized gain (loss) is recognized as component of Renewable Power revenues in the consolidated statement of operations.

Transportation fuel — Fuel Purchase Agreements

We own Fueling Stations for use by customers under fuel sale agreements. We bill these customers at an agreed upon price for each gallon sold and recognize revenue based on the amounts invoiced in accordance with the “right to invoice” practical expedient. These contracts may contain an embedded lease of the equipment which we account for as operating lease revenue. For some public stations where there is no contract with the customer, we recognize revenue at the point in time that the customer takes control of the fuel.

Interstate Gas Pipeline Delivery

We have agreements with two natural gas producers whereby we are contracted to transport the producers’ gas to an agreed delivery point on an interstate gas pipeline via our RNG gathering system. Revenue is recognized over time using the output method which is based on quantity of natural gas transported.

Environmental Attributes

We generate RECs, RINs, ISCC Carbon Credits and LCFS credits. These Environmental Attributes are sold to third parties that utilize these credits in order to comply with federal and state requirements. Revenue is recognized at the point in time when the credits are transferred to and accepted by the third party buyer. We also provide Environmental Attributes generation and monetization services to customers that own renewable gas generation facilities and we recognize revenues from these services when the credits are minted on behalf of the customer.

Operation and Maintenance

We have operating and maintenance agreements pursuant to which we operate, maintain, and repair landfill site gas collection systems. Revenue is based on the volume per million British thermal units (“MMBtu”) of landfill gas collected and the MWhs produced at that site. This revenue is recognized as Renewable Power revenue when landfill gas is collected and Renewable Power is delivered. In addition, we have operations and maintenance agreements in which we are contracted to maintain and repair Fueling Stations. Revenue is based on the volumes of gas dispensed at the site. This revenue is recognized as Fuel Station Services revenue when the site dispenses gas.

Construction Type Contracts — Third Party

We have various fixed price contracts for the construction of fueling stations for customers. Revenue from these contracts, including change orders, are recognized over time, with progress measured by the percentage of cost incurred to date to estimated total cost for each contract.

The Company provides all third-party construction contracts with a warranty, typically for a period of one year after substantial completion of the construction project. Based on the guidance and indicative factors provided by ASC 606, the Company concluded that it offers assurance-type warranties as it does not provide a service to the customer beyond fixing defects that existed at the time of completion. Therefore, these warranties are accounted for under ASC Topic 460, Guarantees ("ASC 460"), and not as a separate performance obligation.

Generally, the company estimates warranty costs based on historical claims experience, and other factors. Actual warranty claims may differ from the estimates, and adjustments to the liability are made as necessary.

Impairment of Goodwill

When a business is acquired, goodwill is recognized to reflect any future economic benefits that are not separately recognized, such as synergies. For the purposes of impairment testing, U.S. GAAP requires goodwill to be allocated to reporting unit(s) at the acquisition date and to be tested for impairment at least annually, and in between annual tests whenever events or changes in circumstances indicate that the respective reporting unit’s fair value is less than its carrying value. Significant judgment is required when identifying the reporting units for goodwill allocation, during our assessment of relevant events and circumstances for qualitative impairment indicators, and when estimating the undiscounted cash flows of reporting unit(s) for quantitative impairment assessments.

Our goodwill impairment assessment is performed during the fourth quarter as of December 31 of each year or at the time facts or circumstances indicate that a reporting unit’s goodwill may be impaired. In conformity with GAAP, we

generally first perform a qualitative assessment over whether it is more likely than not that a reporting unit’s fair value is less than its carrying value to determine if a quantitative assessment is required. If, after performing the qualitative assessment, we conclude it is more likely than not that the fair value of the reporting unit is less than its carrying value, then a quantitative test is required. Our qualitative assessment includes evaluation of relevant events and circumstances, such as, macroeconomic conditions, industry and market considerations, cost factors, overall performance, and other relevant events.

When applying a quantitative assessment, we use a combination of income and market valuation methodologies. Specifically, we employ a discounted cash flow analysis (DCF) and the guideline public company method. This approach results in a fair value measurement based on significant inputs that are not observable in the market, categorizing it within Level 3 of the fair value hierarchy. Key assumptions in the DCF projection include growth in RIN prices, future sales volumes based on production capacities, and terminal value based on a range of terminal earnings before interest, taxes, depreciation, and amortization (EBITDA). The future cash flows are discounted to present value using the weighted average cost of capital (WACC) of the company and its closest competitors.

As of December 31, 2024, we performed a quantitative assessment for Goodwill in our RNG Fuel segment and determined that there is no impairment necessary on the goodwill recorded in the books as of December 31, 2024.

Impairment of Long-Lived Assets

Our long-lived assets held and used with finite useful lives including plant equipment, buildings, patents, and PPAs are reviewed for impairment whenever events or changes in circumstances indicate that the asset group may not be recoverable. In determining the asset group, we assess the interdependency of revenues between assets, shared cost structures, the interchangeability of assets used in operations, and how assets are managed and utilized by the business. Events that may trigger a recoverability assessment include a significant adverse change in the extent or manner in which the long-lived asset group is being used or in its physical condition, and the expectation that, more likely than not, the long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset group to future net undiscounted cash flows expected to be generated by the asset group. Our cash flow estimates reflect conditions and assumptions that existed as of the measurement date which is the same as the triggering event date. The assets are considered recoverable and an impairment loss is not recognized when the undiscounted net cash flows exceed the net carrying value of the asset group. If the assets are not recoverable, then an impairment loss is recognized to the extent that the carrying value of the asset group exceeds its fair value. We base the fair value of our assets or asset groups off of the estimated discounted future cash flows using market participant assumptions. Alternatively, we use cost approach to measure fair value of our assets or asset groups. The cost approach is based on the premise that a prudent investor would pay no more for an asset of similar utility than its replacement or reproduction cost. The cost to replace the asset would include the cost of constructing a similar asset of equivalent utility at prices applicable at the time of the valuation date. To arrive at an estimate of the fair value using the cost approach, the replacement cost new is determined and reduced for depreciation of the asset. Replacement cost new is defined as the current cost of producing or constructing a similar new item having the nearest equivalent utility as the property being valued. Assets disposed of are reported at the lower of the carrying amount or fair value less selling costs. Significant judgment is required when determining asset group composition, during our assessment of relevant events and circumstances, when determining an appropriate discount rate, and when estimating the undiscounted and discounted future cash flows of the asset group.

Based on our assessment for the year ended December 31, 2024, the impairment recorded on our Plant, Property and Equipment amounted $2.0 million.

Fair Value Measurements

The objective of a fair value measurement is to estimate the exit price, which is the price that would be received to sell an asset or paid to transfer a liability that the Company holds, in an orderly market transaction at the measurement date. We follow GAAP guidance which establishes a three-tier hierarchy for inputs used in fair value measurements, as well as prioritizes valuation techniques that maximize the use of observable inputs and minimizes the use of unobservable inputs. In summary, level 1 inputs are considered the most observable inputs and are more specifically the unadjusted quoted price for identical assets or liabilities in an active market the Company has access to. Level 2 inputs are considered less observable inputs such as quoted prices for similar assets or liabilities in an active market the Company has access to. Lastly, level 3 inputs are unobservable inputs in which little to no market activity exists for the asset or liability at the measurement date. As such, level 3 estimates are subject to a more significant level of estimation uncertainty. Furthermore, when multiple inputs are used and are categorized in different levels of the input hierarchy, then the fair value measurement

in its entirety is categorized in the same level as its lowest level input that is significant to the fair value measurement. Our assessment of the significance of an input to a fair value measurement requires judgment and may affect the fair value measurement’s placement in the fair value hierarchy.

Refer to Note 9. Derivative Financial Instruments and Fair Value Measurements, to our consolidated financial statements, for details on our assets and liabilities regularly recorded at fair value and the respective placements in the fair value hierarchy.

The Company accounts for income taxes in accordance with ASC Topic 740, Accounting for Income Taxes (“ASC Topic 740”), which requires the recognition of tax benefits or expenses on temporary differences between the financial reporting and tax bases of its assets and liabilities by applying the enacted tax rates in effect for the year in which the differences are expected to reverse. Such net tax effects on temporary differences are reflected on the Company’s consolidated balance sheets as deferred tax assets and liabilities. Deferred tax assets are reduced by a valuation allowance when the Company believes that it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized.

Refer to Note 15. Income Taxes, to our consolidated financial statements, for additional information.

Emerging Growth Company Status

We are an emerging growth company as defined in the JOBS Act. The JOBS Act provides emerging growth companies with certain exemptions from public company reporting requirements for up to five fiscal years while a company remains an emerging growth company. As part of these exemptions, we need only provide two fiscal years of audited financial statements instead of three, we have reduced disclosure obligations such as for executive compensation, and we are not required to comply with auditor attestation requirements from Section 404(b) of the Sarbanes-Oxley Act regarding our internal control over financial reporting. Additionally, the JOBS Act has allowed us the option to delay adoption of new or revised financial accounting standards until private companies are required to comply with new or revised financial accounting standards.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates and assumptions of the Company relate to the useful lives of property, plant and equipment, goodwill impairment, fair value of the deconsolidated VIEs, the value of stock-based compensation, asset retirement obligations and the fair value of derivatives including earnout liabilities and commodity swap contracts.

Key Factors and Trends Influencing our Results of Operations

The principal factors affecting our results of operations and financial condition are the markets for RNG, Renewable Power, and associated Environmental Attributes, and access to suitable biogas production resources. Additional factors and trends affecting our business are discussed in "Risk Factors" elsewhere in this report.55

The principal factors affecting our results of operations and financial condition are the markets for RNG, Renewable Power, and associated Environmental Attributes, access to suitable biogas production resources, the regulatory environment of our industry, and the seasonality of demand and pricing for our products. Additional factors and trends affecting our business are discussed in "Risk Factors" elsewhere in this report.

Market Demand for RNG

Demand for our converted biogas and associated Environmental Attributes, including RINs and LCFS credits, is heavily influenced by United States federal and state energy regulations together with commercial interest in renewable energy products. Markets for RINs and LCFS credits arise from regulatory mandates that require refiners and blenders to incorporate renewable content into transportation fuels. The EPA annually sets proposed renewable volume obligations ("RVOs") for D3 RINs in accordance with the mandates established by the Energy Independence and Security Act of 2007. In June 2023, the EPA set RVOs for 2023 through 2025 via a new Set rule. This 3 year RVO is expected to reduce volatility in RIN pricing for the associated period. On the state level, the economics of RNG are enhanced by low-carbon fuel initiatives, particularly well-established programs in California, Washington and Oregon (with several other states also actively considering LCFS initiatives similar to those in California, Washington and Oregon). Federal and state regulatory developments could result in significant future changes to market demand for the RINs and LCFS credits we produce. This would have a corresponding impact to our revenue, net income, and cash flow.

developments could result in significant future changes to market demand for the RINs and LCFS credits we produce. This would have a corresponding impact to our revenue, net income, and cash flow.

Transportation, including heavy-duty trucking, generates approximately 30% of overall carbon dioxide and other climate-harming GHG emissions in the United States, and transitioning this sector to low and negative carbon fuels is a critical step towards reducing overall global GHG emissions. The adoption rate of RNG-powered vehicles by commercial transportation fleets will significantly impact demand for our products.

We are also exposed to the commodity prices of natural gas and diesel, which serve as alternative fuel for RNG and therefore impact the demand for RNG.

Renewable Power Markets

We also generate revenues from sales of Renewable Power generated by our biogas-to-Renewable Power projects, and associated ~~ISCC Carbon Credits and~~ RECs. ~~ISCC Carbon Credits and~~ RECs exist because of legal and governmental regulatory requirements in Europe and the United States, ~~respectively,~~ and a change in law or in governmental policies concerning Renewable Power, LFG, or ~~ISCC Carbon Credits or~~ RECs could affect the market for, and the pricing of, such power and credits.

We periodically evaluate opportunities to convert existing Renewable Power projects to RNG production. We have been negotiating with several of our landfill and Renewable Power counterparties to enter into arrangements that would enable the LFG resource to produce RNG. Changes in the price we receive for Renewable Power, ~~associated ISCC Carbon Credits~~ and associated RECs, together with the revenue opportunities and conversion costs associated with converting our LFG sites to RNG production, could have a significant impact on our future profitability.

Regulatory landscape

We operate in an industry that is subject to and currently benefits from environmental regulations. Government policies can increase demand for our products by providing incentives to purchase RNG and Environmental Attributes. These government policies are modified and in flux constantly and any adverse changes to these policies could have a material effect on the demand for our products. For more information, see our risk factor titled "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." Government regulations have become increasingly stringent and complying with changes in regulations may result in significant additional operating expenses.

Seasonality

We experience seasonality in our results of operations. Sale of RNG may be impacted by higher consumption by some of our customers during summer months. Additionally, the price of RNG is higher during the fall and winter months due to increase in overall demand for natural gas during the winter months. Revenues generated from our renewable electricity projects in the northeast U.S., all of which sell electricity at market prices, are affected by warmer and colder weather, and therefore a portion of our quarterly operating results and cash flows are affected by pricing changes due to regional temperatures. These seasonal variances are managed in part by certain off-take agreements at fixed prices.

Key Components of Our Results of Operations

We generate revenues from the sale of RNG ~~fuel~~Fuel, Renewable Power, and associated Environmental Attributes, as well as from the construction, fuel supply, and servicing of Fueling Stations for commercial transportation vehicles using natural gas to power their fleets. These revenue sources are presented in our ~~statement~~consolidated statements of operations under the following captions:

(1) Design Capacity for RNG facilities is measured as the volume of feedstock biogas that the facility is capable of accepting at the inlet and processing during the associated period. Design Capacity is presented as OPAL’s ownership share (i.e., net of joint venture partners’ ownership) of the facility and is calculated based on the number of days in the period. New facilities that come online during a quarter are pro-rated for the number of days in commercial operation.

(2) Inlet Design Capacity Utilization is measured as the Volume of Inlet Gas for a period, divided by the total Design Capacity for such period. The Volume of Inlet Gas varies over time depending on, among other factors, (i) the quantity and quality of waste deposited at the landfill, (ii) waste management practices by the landfill, and (iii) the construction, operations and maintenance of the ~~landfill~~LFG ~~gas~~ collection system used to recover the ~~landfill gas~~LFG. The Design Capacity for each facility will typically be correlated to the amount of ~~landfill~~LFG ~~gas~~ expected to be generated by the landfill during the term of the related gas rights agreement. The Company expects Inlet Design Capacity Utilization to be in the range of 75-85% on an aggregate basis over the next several years. Typically, newer facilities perform at the lower end of this range and demonstrate increasing utilization as they mature and the biogas resource increases at open landfills.

(3) Utilization of Inlet Gas is measured as RNG Fuel Volume Produced divided by the Volume of Inlet Gas. Utilization of Inlet Gas varies over time depending on availability and efficiency of the facility and the quality of landfill gas (i.e., concentrations of methane, oxygen, nitrogen, and other gases). The Company generally expects Utilization of Inlet Gas to be in the range of 80% to 90%.58

Revenue from Brown Gas Sales increased $0.5 million, also primarily due to ~~the impact of Prince William and Polk coming online in 2024. Additionally, there was $0.5 million increase in revenues earned from providing management services to unconsolidated entities.~~

$3.5 million increase in price and a $2.9 million increase in volume, as well as $2.5 million driven by commencement of operations at new facilities and a $4.0 million increase in the sale of environmental attributes. The increase in environmental attributes was primarily related to a $5.0 million increase due to timing of green gas sales, a $15.2 million increase from the new facilities (Prince William and Polk), a $1.4 million increase in RIN volume, and a $17.7 million decrease due to RIN price reduction.

Also within Fuel Station Service there was a $6.8 million increase in OPAL owned stations due to higher volumes, and a $3.2 million increase in service and maintenance revenues from an increased number of stations serviced, partially offset by a $9.2 million decrease in construction revenues primarily related to ~~timing as new 2024 projects started construction later in~~ the ~~year.~~ following:

65Environmental attributes and RNG marketing revenue increased primarily due to increase in RIN sales driven by $23.1 million higher RIN volumes, partially offset by $12.7 million lower RIN prices, and $8.6 million increase in LCFS sales due to higher dispensing volumes. OPAL owned stations revenue increased by $3.3 million primarily due to higher GGE volumes. Third party station service and maintenance increased by $3.0 million driven by higher service volumes resulting from increased GGE volume of $3.9 million partially offset by $1.1 million in lower service rates. Construction revenue increased by $9.3 million mainly due to project construction timing. Lease revenues increased by $13.2 million as a result of sales‑type lease revenue recognition increase of $7.7 million and higher GGE volumes of $5.5 million associated with operating leases.

At the initial closing on March 6, 2026, the investor purchased 1.2 million preferred units for aggregate proceeds of $120.0 million. OPAL Fuels may, in its sole discretion, require the investor to fund up to an additional $60.0 million within one year of the initial closing, subject to the terms of the subscription agreement.

The Series A preferred units are entitled to preferred quarterly distributions at a rate of 12% per annum, compounding quarterly, and rank senior to all other classes of equity interests of OPAL Fuels LLC, except for certain existing preferred units to which they are pari passu. In connection with the initial closing, the Company also issued a warrant to the investor to purchase up to 3.0 million shares of the Company’s Class A common stock, subject to vesting, forfeiture, and other terms and conditions.

During the fourth quarter of 2025, Nextera provided notice of its right to require redemption of all outstanding Series A preferred units.

Liquidity and Capital Resources

Liquidity

As of December 31, ~~2024~~2025, our liquidity was $~~223~~168.62 million consisting of $~~178~~128.4 million of unused capacity under our $450 million senior secured credit facility, $2015.94 million of unused capacity under the associated revolver, and $24.34 million of cash, cash equivalents. Refer to Note 76. Loans.

We expect that our available cash together with our other assets, expected cash flows from operations, and access to expected sources of capital will be sufficient to meet our existing commitments for a period of at least twelve months from the date of this report. Any reduction in demand for our products or our ability to manage our production facilities may result in lower cash flows from operations which may impact our ability to make investments and may require changes to our growth plan.

To fund future growth, we anticipate seeking additional capital through equity or debt financings. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our project development efforts. We may be unable to obtain any such additional financing on acceptable terms or at all. Our ability to access capital when needed is not assured and, if capital is not available when, and in the amounts, needed, we could be required to delay, scale back or abandon some or all of our development programs and other operations, which could materially harm our business, prospects, financial condition, and operating results.

As part of our operations, we have arrangements for office space for our corporate headquarters under the Administrative Services Agreement as well as operating leases for office space, warehouse space, and our vehicle fleet.

We intend to make payments under our various debt instruments when due and pursue opportunities for earlier repayment and/or refinancing if and when these opportunities arise. In the fourth quarter of 2025, NextEra exercised its redemption option to redeem the preferred units. Refer to Note 11. Redeemable Non-controlling Interest, Redeemable Preferred Non-controlling Interest and Stockholders' Deficit for additional details.

In the event the Company does not redeem the Series A preferred units when requested, NextEra will have the following rights and remedies: (1) NextEra’s affiliate may extend the RNG Marketing Agreement by 12 months; or (2) the dividend rate would increase depending on the length of time the Series A preferred units remain unredeemed to up to 20% per annum, and if more than $25,000,000 preferred equity is outstanding for more than six months after November 29, 2025, NextEra may appoint a director to OPAL Fuel Inc.’s Board of Directors; or (3) NextEra may convert the Series A preferred equity into common equity of the OPAL Fuels LLC at a conversion price at a 20% to 30% discount to their value (the discount is 20% during the first 12 months after November 29, 2025, 25% for the next 12 months thereafter and 30% thereafter).

Subsequent to December 31, 2025, the Company completed a $120.0 million preferred equity issuance and drew approximately $128.4 million under its term loan facility, which was used to redeem $100.0 million of outstanding preferred units and repay a portion of the revolving loan facility. See Note 16. Subsequent Events for additional details regarding these transactions.

Net ~~Cash~~cash ~~Used~~used in ~~Investing~~investing ~~Activities~~activities

Net cash used in investing activities for the year ended December 31, ~~2024~~2025 was $~~134~~77.63 million, ana ~~increase~~decrease of $6057.4 2 million compared to the $74134.16 million used in investing activities for the year ended December 31, 2023. This was primarily driven by a decrease in cash from sale of short term investments of $45.2 million, higher payments made for the construction of various RNG generation and dispensing facilities in 2024 ~~compared to 2023 of $13~~.~~4 million,~~ an increase of $13.3 million in contributions to equity method investments, a $0.5 million decrease in distributions from equity method investments, offset by a decrease from deconsolidation of VIEs of $11.9 million in 2023.

~~Net~~This ~~Cash~~was ~~Provided~~primarily driven by ~~Financing~~a ~~Activities~~decrease in payments made for the construction of various RNG generation and dispensing facilities in 2025 compared to 2024, an increase in distributions received from equity method investments, higher proceeds from the disposal of property, plant and equipment as well as an increase in cash received from the settlement of notes receivable. This increase was partially offset by higher contributions made to equity method investments and lower proceeds from sale of short-term investments.

Net cash provided by financing activities for the year ended December 31, 2024 was $83.5 million, an increase of $77.6 million compared to the $5.9 million provided by financing activities for the year ended December 31, 2023. This increase was primarily driven by an increase of $158.9 million due to lower repayments on the Senior Secured Facility, the Convertible Note payable and OPAL Term Loan facilities in current year, an increase of $16.4 million due to no payment on termination of put options in current year, an increase of $3.4 million due to lower preferred dividend payments in the current year, offset by a $87.2 million decrease in proceeds from the OPAL Term Loan, net of issuance costs, decrease in proceeds from non-controlling interests of $12.8 million, and a decrease of $0.8 million in reimbursement of financing costs by a joint venture partner.

Net cash provided by financing activities for the year ended December 31, 2025 was $41.6 million, a decrease of $41.9 million compared to the $83.5 million provided by financing activities for the year ended December 31, 2024.

This was primarily driven by a decrease in proceeds from long‑term loans and an increase in repayments, partially offset by lower preferred dividend payments.

Capital expenditures and other cash commitments

We require cash to fund our capital expenditures, operating expenses, and working capital and other requirements, including costs associated with fuel sales; outlays for the design and construction of new Fueling Stations and RNG production facilities; debt repayments and repurchases; maintenance of our electrification production facilities supporting our operations, including maintenance and improvements of our infrastructure; supporting our sales and marketing activities, including support of legislative and regulatory initiatives; any investments in other entities; any mergers or acquisitions, including acquisitions to expand our RNG production capacity; pursuing market expansion as opportunities arise, including geographically and to new customer markets; and to fund other activities or pursuits and for other general corporate purposes.

As of December 31, ~~2024~~2025, we currently anticipate spending of approximately $~~194~~154.0 million in capital expenditures for the next 12 months for RNG projects, ~~and~~ fuel stations ~~currently under construction~~ and our share of contributions in our equity method investment projects. This includes projects which have not been fully committed. These expenditures do not include any expected contributions from our joint venture partners and primarily relate to our development and construction of new renewable energy facilities and the purchase of equipment used in our Fueling Station services and Renewable Power operations.

In addition to the above, we also have lease commitments on our vehicle fleets and office leases and quarterly amortization payment obligations under various debt facilities. Please see Note 76. ~~Borrowings~~Loans and Note 87. Leases to our consolidated financial statements for additional information.

We plan to fund these expenditures primarily through cash on hand, cash generated from operations and availability under existing debt facilities.

Critical Accounting Estimates

The preparation of our consolidated financial statements requires management to make estimates and assumptions that involve significant judgment and that could materially affect the amounts reported in our financial statements. These estimates relate to matters that are highly uncertain and require management to exercise judgment in selecting the underlying assumptions. If actual results differ from those assumptions, our financial condition or results of operations could be materially affected.

Certain of these estimates are particularly important because they involve assumptions that are inherently uncertain and could materially impact our financial statements if actual results differ. These critical accounting estimates require us to make difficult, subjective, and complex judgments about matters that are inherently uncertain, and changes in those estimates could result in materially different outcomes. The following discussion highlights the estimates that we believe involve the most significant judgment and present the greatest potential for material impact on our consolidated financial statements.

Construction Contracts

The recognition of revenue on our third‑party construction contracts requires significant judgment and involves estimates that are inherently subjective. These fixed‑price contracts are accounted for using an over‑time revenue recognition model, under which progress is measured based on the percentage of costs incurred to total estimated costs for each project. Determining the total expected cost to complete a project—including labor, materials, subcontractors, change orders, and contingencies—requires management to make assumptions regarding project scope, productivity, pricing, and timing. Changes in any of these estimates, including revisions to anticipated costs or outcomes of outstanding change orders, can materially affect the amount and timing of revenue and margin recognized.

Impairment of Goodwill

Evaluating goodwill for potential impairment requires the use of estimates and assumptions that involve significant judgment and could materially affect our financial results. We assess goodwill for impairment at least annually, or more frequently if events or changes in circumstances indicate that the fair value of a reporting unit may be less than its carrying amount.

A key source of estimation uncertainty relates to the determination of the fair value of our reporting units when a quantitative impairment test is required. Fair value estimates rely on unobservable inputs and require management to make assumptions about future performance, market conditions, and discount rates. These assumptions include projected cash flows, expectations for growth in RIN prices, future production and sales volumes, terminal value estimates, and the

selection of an appropriate weighted-average cost of capital. These inputs are inherently uncertain and highly sensitive to changes in market conditions.

Because fair value measurements depend on these complex judgments, changes in assumptions—or differences between projected and actual results—could result in a material impairment charge in future periods.

There was no impairment for the year ended December 31, 2025.

Impairment of Long-Lived Assets

Assessing long‑lived assets for potential impairment requires the use of significant estimates and assumptions that involve material judgment. These assets include plant equipment, buildings, patents, and other assets which are grouped and tested for recoverability when events or changes in circumstances indicate that the carrying amount may not be recoverable. Determining the appropriate asset group requires management to exercise judgment in evaluating how assets are used in the business, the degree to which cash flows are interdependent, and how operations are managed.

When a triggering event occurs, we estimate future undiscounted cash flows for the applicable asset group. These estimates require assumptions about future operating performance, commodity pricing, production levels, operating costs, and asset utilization. Because these estimates reflect conditions that existed at the time of the assessment and extend over long periods, they are inherently uncertain. If the estimated undiscounted cash flows are less than the carrying amount of the asset group, we must estimate fair value, which adds further judgment and complexity.

Fair value measurements for long‑lived assets often rely on discounted cash flow models that require additional significant assumptions, including discount rates, long‑term growth expectations, and market participant assumptions. In certain cases, we may apply a cost‑based approach, which requires estimating replacement cost, physical deterioration, and economic obsolescence. Changes in any of these assumptions, or differences between estimated and actual results, could materially affect the fair value conclusions and may result in a material impairment charge.

Because both recoverability assessments and fair value measurements depend on management’s assumptions about future economic and operating conditions, these evaluations involve a high degree of subjectivity and represent one of the most judgment‑dependent areas of our financial reporting.

There was no impairment for the year ended December 31, 2025.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is not required to provide the information required by this Item as it is a “smaller reporting company.” However, we note that we are exposed to market risks related to Environmental Attribute pricing, commodity pricing, changes in interest rates and credit risk with our contract counterparties. We currently have no foreign exchange risk and do not hold any derivatives or other financial instruments purely for trading or speculative purposes.

70We employ various strategies to economically hedge these market risks, including derivative transactions relating to commodity pricing and interest rates. Any realized or unrealized gains or losses from our derivative transactions are reported within corporate revenue and other income/expense in our consolidated financial statements. For information about our gains or losses with respect to our derivative transactions and the fair value of such financial instruments, see Note 8. Derivative Financial Instruments and Fair Value Measurements, to our consolidated financial statements.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our Co-Chief Executive Officers and our Chief Financial Officer (our co- principal executive officers and principal financial officer, respectively), evaluated, as of the end of the period covered by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. The term “disclosure controls and procedures,” as defined in the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on that evaluation of our disclosure controls and procedures as of December 31, ~~2024~~2025, our Co-Chief Executive Officers and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective for the period covered by this report.

Management's Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our Co-Chief Executive Officers and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting. Management has adopted the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the results of our evaluation, our management including our Co-Chief Executive Officers and Chief Financial Officer concluded that our internal control over financial reporting was effective as of December 31, ~~2024~~2025.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended December 31, ~~2024~~2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

Insider Trading Arrangements

During the fiscal quarter ended December 31, ~~2024~~2025, none of our directors or executive officers adopted or terminated any contract, instruction or written plan for the purchase or sale of Company securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any "non-Rule 10b5-1 trading arrangement."

Wasatch Resource Recovery Facility

On March 17, 2025, Fortistar, through its subsidiary Wasatch RNG LLC (“Wasatch RNG”), acquired all of the limited liability company interests outstanding in Alpro SD, LLC (“Alpro” and such acquired interest, the “Alpro Interest”). Alpro owns a 50% limited liability company interest in Wasatch Resource Recovery, LLC (the “Project” or “Wasatch” and such ownership interest, the “Wasatch Interest”) and a 50% tenancy-in-common interest in certain real estate and operating assets used by Wasatch (the “Project Interest”). As a result of the acquisition, Wasatch RNG has the option to increase the Wasatch Interest and the Project Interest.

The Project captures and converts biogas generated from food waste to produce pipeline quality renewable natural gas (RNG). The Project generates revenue from long-term contracted gas sales, tipping fees, and digestate (fertilizer) sales. The conversion of food waste to RNG presents a potential growth and diversification opportunity for OPAL Fuels.

OPAL Term Loan

In connection with the Credit Agreement Amendment, the Borrower paid the Administrative Agent, for the account of each lender, a one-time nonrefundable fee of $1.2 million.

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors

OPAL Fuels Inc.

White Plains, NY

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of OPAL Fuels Inc. ~~and its subsidiaries~~ (the “Company”) as of December 31, ~~2024~~2025 and ~~2023~~2024, the related consolidated statements of operations, ~~and~~ comprehensive income, changes in redeemable non-controlling interest, redeemable preferred non-controlling interest and stockholders~~’(deficit)~~' ~~equity~~deficit, and cash flows for each of the ~~two~~ years inthen ~~the period~~ ended ~~December 31~~, ~~2024,~~ and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, ~~2024~~2025 and ~~2023~~2024, and the results of its operations and its cash flows for ~~each of~~ the ~~two~~ years inthen ~~the period~~ ended ~~December 31~~, ~~2024,~~ in conformity with accounting principles generally accepted in the United States of America.

Related Parties

As discussed in Note 109. Related Parties to the consolidated financial statements, the Company has entered into significant transactions with NextEra Energy Marketing, LLC (“NextEra”) and Fortistar LLC (“Fortistar”), which are related parties. Our opinion is not modified with respect to this matter.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ BDO USA, P.C.

We have served as the Company’s auditor since 2016.

include, but are not limited to, the VIE's purpose and design and the risks passed through to investors, the voting interests of the VIE, management, service and/or other agreements of the VIE, involvement in the VIE's initial design, and the existence of explicit or implicit financial guarantees. If we are the party with the power over the most significant activities, we meet the "power" criteria of the primary beneficiary. If we do not have the power over the most significant activities or we determine that all significant decisions require consent of a third-party, we do not meet the "power" criteria of the primary beneficiary.

We assess our variable interests in a VIE both individually and in aggregate to determine whether we have an obligation to absorb losses of or a right to receive benefits from the VIE that could potentially be significant to the VIE. The determination of whether our variable interest is significant to the VIE requires judgment. In determining the significance of our variable interest, we consider the terms, characteristics and size of the variable interests, the design and characteristics of the VIE, our involvement in the VIE, and our market-making activities related to the variable interests.

Our variable interests in each of our VIEs arise primarily from our ownership of membership interests, construction commitments, our provision of operating and maintenance services, and our provision of environmental credit processing services to VIEs.

As of December 31, 2024 and 2023, the Company accounted for its ownership interests in Pine Bend RNG LLC ("Pine Bend"), Noble Road RNG LLC ("Noble Road"), Paragon RNG LLC ("Paragon"), Emerald RNG LLC ("Emerald"), Sapphire RNG LLC ("Sapphire"), Land2Gas LLC (the "SJI Joint Venture"), Atlantic RNG LLC ("Atlantic"), Burlington RNG LLC ("Burlington") and GREP BTB Holdings LLC ("GREP") under the equity method.

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates and assumptions of the Company include the residual value of the useful lives of our property, plant and equipment, the fair value of stock-based compensation, asset retirement obligations, the estimated losses on our trade receivables, percentage completion for revenue recognition, incremental borrowing rate for calculating the right-of-use assets and lease liabilities, the impairment assessment of goodwill, and the fair value of derivative instruments. Actual results could differ from those estimates.

The significant estimates and assumptions of the Company include the residual value of the useful lives of our property, plant and equipment, the fair value of long-lived assets, asset retirement obligations, percentage completion for revenue recognition, incremental borrowing rate for calculating the right-of-use assets and lease liabilities, and the fair value of the reporting units of goodwill.

~~F-11~~In July 2025, the FASB issued ASU 2025‑05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments provide a practical expedient applicable to all entities for estimating expected credit losses on current accounts receivable and current contract assets that arise under ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"), permitting the assumption that existing conditions at the balance‑sheet date will remain unchanged over the remaining life of such assets. The Company adopted this standard effective January 1, 2025. The adoption did not have a material effect on our consolidated financial statements.

In September 2025, the FASB issued ASU 2025‑06, Intangibles — Goodwill and Other (Topic 350): Internal‑Use Software — Targeted Improvements to the Accounting for Internal‑Use Software. The amendments modernize the guidance for capitalizing costs of internally‑developed software by removing references to defined development stages and instead focusing on two principal criteria: (1) management has authorized and committed to funding the project, and (2) it is probable that the project will be completed and the software will be used to perform the intended function. This ASU also provides new guidance regarding how to evaluate whether “probable-to-complete” criteria has been met. The ASU is effective for fiscal years beginning after December 31 15, 2027, ~~2024~~including interim periods within those years, with early adoption permitted. The Company adopted this standard effective January 1, 2025 prospectively. The adoption did not have a material effect on the Company’s financial position, results of operations, cash flows or disclosures.

~~In March 2023, the FASB issued~~ Accounting ~~Standards~~Pronouncements Update No. 2023-01, Leases (Topic 842) (the "Update"). The Update requires the entities to classify and account for a leasing arrangement between entities under common control on the same basis as an arrangement with an unrelated party. The Update also requires that leasehold improvements associated with common control leases be amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset and accounts for the underlying asset as a transfer between entities under common control through an adjustment to equity if and when the lessee no longer controls the use of the underlying asset. The amendments in this Update are effective for fiscal years beginning after December 15, 2023 including interim fiscal periods within those fiscal years. The Company adopted ASU 2023-01 in the year ended December 31, 2024. The adoption did not ~~have~~yet aAdopted ~~material effect on the Company’s financial position, results of operations, cash flows or disclosures.~~

The ASU is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The amendments are to be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact that this guidance will have on the disclosures within our consolidated financial statements.

~~In December 2023, the FASB issued Accounting Standards Update No. 2023~~F-09, Income Taxes (“Topic 740”): Improvements to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures in order to provide information to assist key stakeholders in better assessing how the Company’s operations and related tax risks and tax planning and operational opportunities affect the Company’s tax rate and prospects for future cash flows. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. This ASU becomes effective for public companies for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements and related disclosures.10

Cash, cash equivalents, and restricted cash consisted of the following as of December 31, ~~2024~~2025 and ~~December 31, 2023~~2024:


	December 31, 2025		December 31, 2024

Long-term assets:
Restricted cash - non - current	2,700		2,298
Total cash, cash equivalents, and restricted cash	$	28,318	$	27,580

Accounts Receivable, Net

Accounts receivable represent amounts due from the sale of products and services for which the Company has an unconditional right to payment. Accounts receivable are stated at net realizable value, net of an allowance for credit losses. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability including past‑due status and made judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.

Contract Balances

Contract assets consist primarily of costs and estimated earnings in excess of billings and retainage receivables. Costs and estimated earnings in excess of billings represent unbilled amounts earned and reimbursable under construction contracts and arise when revenues have been recognized but amounts are conditional and have yet to be billed under the terms of the contract. Amounts become billable in accordance with contract terms, generally based on progress toward completion and the achievement of contractual milestones. Cost and estimated earnings in excess of billings amounted to $6,489 and $8,547 as of December 31, 2025 and 2024.

Contract liabilities consist of billings in excess of costs and estimated earnings and other deferred construction revenue. Billings in excess of costs and estimated earnings represent amounts billed to or collected from customers in advance of the satisfaction of the related performance obligations. These amounts are recognized as revenue as the Company satisfies its performance obligations over the remaining contract term.

During the year ended December 31, 2025, the Company recognized revenue of $6,274 that was included in contract liabilities at December 31, 2024. During the year ended December 31, 2024, the Company recognized revenue of $3,746 that was included in contract liabilities at December 31, 2023.

Parts Inventory

Parts inventory, also referred to as supplies inventory, consists of shop spare parts inventory and construction site parts inventory. Parts inventory is stated at historical cost, which is determined using the average cost method, and is recorded at the lower of cost or net realizable value. An annual review of inventory is performed to identify obsolete items.

Prepaid Expense and Other Current Assets

Prepaid expenses and other current assets consist primarily of prepaid insurance, environmental credits held for sale, non-monetary asset and other miscellaneous current assets expected to be realized within one year.


	Year Ended December 31,
	2025		2024
Fuel tax credits receivable	$	3,264	$	5,639
Prepaid insurance	3,767		4,001
Environmental credits held for sale	3,758		6,466
Other	5,229		7,477
Total prepaid expense and other current assets	$	16,018	$	23,583

The Company receives non‑cash consideration in the form of RINs and LCFS credits in exchange for dispensing and credit monetization services. Environmental credits held for sale are recognized within current assets. The Company's accounting policy election is to account for environmental credits received as inventory as they are held for sale and not retained for use. The environmental credits received are initially measured at their estimated fair value at contract inception. For internally generated environmental credits, the credits are accounted for as government incentives rather than outputs and, accordingly, no associated value is recorded. These credits are subsequently measured at the lower of cost and net realizable value at each balance sheet date. For the years ended December 31, 2025 and 2024, the Company recorded $17,828 and $10,365 as part of cost of sales - fuel station services in its consolidated statements of operations to adjust environmental credits held for sale to lower of cost and net realizable value.

Property, Plant, and Equipment, Net

Property, plant, and equipment are recorded at historical cost, except for amounts attributable to asset retirement obligations, which are recorded at their estimated fair value when the obligation is incurred. Direct costs associated with the construction of assets, as well as renewals and betterments that materially improve or extend the useful lives of the assets, are capitalized.

The Company capitalizes costs related to the development and construction of new projects when management determines that there is a significant likelihood that the project will be completed and placed in service for its intended use. This determination is based on the achievement of key milestones, including, but not limited to, the receipt of required permits and the execution of major contracts, such as gas rights agreements, gas transportation arrangements, and engineering, procurement, and construction contracts. Costs incurred prior to the achievement of these milestones are expensed as incurred. Replacements, routine maintenance, and repairs that do not materially improve or extend the useful lives of the respective assets are expensed as incurred. Major maintenance is a component of maintenance expense and encompasses overhauls of internal combustion engines, gas compressors and electrical generators. Major maintenance is expensed as incurred.

The Company capitalizes interest incurred on its general borrowings during the construction period until the related assets are substantially complete and ready for their intended use.

Depreciation is computed using the straight‑line method over the estimated useful lives of the assets as follows:

However, actual future market prices and project costs could vary from the assumptions used in our estimates and the impact of such variations could be material.

Net income per share

The basic income per share of Class A common stock is computed by dividing the net income (loss) attributable to Class A common stockholders by the weighted average number of Class A common stock outstanding during the period.

The Class B common stock and D common stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock and Class D common stock under the two-class method has not been presented.

Accounts Receivable, Net

F-14

Accounts receivable represent amounts due from the sale of RNG, natural gas, gas transportation, construction contracts, service contracts, environmental attributes, electricity, capacity, and LFG for which the Company has an unconditional right to payment. The accounts receivable are the net estimate realizable value between the invoiced accounts receivable and allowance for credit losses. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and made judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.

The Company did not have an allowance for credit losses as of December 31, 2024 and December 31, 2023.

Fuel Tax Credit Receivable/Payable

At December 31, 2024, the Company accrued federal fuel tax credits of $0.50 per gasoline gallon equivalent of CNG that the Company sold as vehicle fuel in 2024. At December 31, 2024 and 2023, fuel tax credits receivable were $5,639 and $5,345, respectively. Under the terms of its fuel sales agreements with certain of its customers, the Company is obligated to share portions of these tax credits. At December 31, 2024 and 2023, the amounts of fuel tax credits owed to customers were $4,422 and $4,558, respectively. The Company recorded its portion of tax credits earned as a reduction to cost of sales — RNG fuel in the consolidated statements of operations.

In addition, the Company determines the Level 3 fair value measurements based on historical information and current market conditions. An asset retirement obligation is classified as short-term if it is expected to be settled within one year. If the obligation is expected to be settled beyond one year, it is classified as long-term.
