About

Clean Energy Fuels Corp. is a leading renewable energy company focused on the procurement and distribution of renewable natural gas (RNG) and conventional natural gas in the form of compressed natural gas (CNG) and liquefied natural gas (LNG) for the United States and Canadian transportation markets. The company specializes in transforming waste methane from sources such as dairy and livestock waste and landfills into RNG, which serves as a replacement for fossil-based transportation fuels. Clean Energy Fuels Corp. operates fueling stations, designs and builds fueling infrastructure, provides operations and maintenance services, and sells Environmental Credits generated from RNG sales.

Clean Energy Fuels Corp. generates revenue primarily through the sale of RNG and conventional natural gas as vehicle fuel in CNG and LNG forms. Additional revenue streams include the sale of Environmental Credits such as Renewable Identification Numbers (RINs) and Low Carbon Fuel Standard (LCFS) credits, operations and maintenance (O&M) services for fueling stations, station construction and engineering, and the transport and sale of CNG via virtual natural gas pipelines through its subsidiary NG Advantage, LLC. The company also serves non-vehicle customers, including marine cargo ships, aircraft, and industrial users, and leverages government tax credits, grants, and incentives to support its business model.

The company operates through the following segments: Fuel Sales, Sales of Environmental Credits, O&M Services, and Station Construction and Engineering.

• Fuel Sales: This segment involves the sale of RNG and conventional natural gas as CNG and LNG for medium and heavy-duty vehicle use. RNG is sourced from anaerobic digester gas (ADG) and landfill gas (LFG) through long-term supply offtake agreements with third-party producers, including partnerships with TotalEnergies, BP, and Maas Energy, as well as company-owned projects like South Fork. CNG is produced by compressing RNG or conventional natural gas and dispensing it at fueling stations, while LNG is created by cooling the gas to approximately negative 260 degrees Fahrenheit at liquefaction plants such as the Boron Plant in California and the Pickens Plant in Texas. These fuels are sold to fleet customers through contracts or on a per fill-up basis at public access stations.

• Sales of Environmental Credits: This segment generates revenue from the sale of RINs and LCFS credits earned when RNG is used as a transportation fuel. The company sells these credits to obligated parties under federal Renewable Fuel Standard (RFS) and state-level LCFS programs in California, Oregon, New Mexico, and Washington. Revenue from this segment fluctuates based on credit market prices, which in 2025 ranged from $2.05 to $2.50 for RINs and $40.00 to $75.50 for LCFS Credits, as well as regulatory changes and compliance verification processes.

• O&M Services: This segment provides maintenance and operational support for both company-owned and customer-owned fueling stations. Services are backed by over 200 employed technicians, a 24/7 remote monitoring center, technician training programs, and computerized maintenance management systems across the U. S. and Canada. Revenue is typically derived from fixed fees or per-gallon charges based on fuel dispensed at the station, ensuring reliable station performance and uptime for customers.

• Station Construction and Engineering: This segment encompasses the design, construction, and leasing or sale of fueling stations to customers. Since 2008, Clean Energy Fuels Corp. has served as general contractor or supervised third-party contractors to build over 470 natural gas fueling stations. Equipment installed includes compressors, storage tanks, and dispensers, with capabilities to integrate hydrogen fueling and electric vehicle charging infrastructure at station sites, although such additions may involve significant costs.

Clean Energy Fuels Corp. holds a leading position in North America’s renewable natural gas market for transportation, particularly in the volume of RNG dispensed and the number of fueling stations operated. The company estimates it provided 50% and 32% of the RNG used for transportation fuel in California and the United States, respectively, in 2025. Its competitive advantage stems from its extensive fueling infrastructure, long-standing customer relationships, and exclusive access to dispensers that enable Environmental Credit generation— a benefit it believes no other participant matches in scale. While competing with diesel, alternative fuels like renewable diesel and hydrogen, and other natural gas providers, the company leverages its first-mover status and integrated business model to maintain market leadership.

Clean Energy Fuels Corp. serves fleet vehicle operators across heavy-duty trucking, airports, refuse collection, public transit, industrial and institutional energy users, and government fleets. Notable customers include Amazon, Pepsi Frito-Lay, FedEx, Anheuser-Busch, USPS, UPS, Kroger, KeHe Distributors, Kenan Advantage Group, Estes Express, Waste Management, Republic Services, Waste Connections, GFL Environmental, Los Angeles County Metropolitan Transit Authority, New York MTA, and Phoenix Transit. The company also supplies LNG to customers in rocket propulsion, oil fields, marine, and rail applications, and provides CNG through virtual pipelines to industrial users without direct pipeline access via NG Advantage.

Investment Thesis

▲ Bull case

Clean Energy Fuels Corp. is positioned to capitalize on a structural shift in heavy-duty trucking economics driven by persistent diesel price volatility and the proven total cost of ownership advantage of RNG-powered Class 8 trucks using the Cummins X15N engine, which management highlighted as a core growth opportunity despite slower-than-expected adoption. The recent diesel price surge of $1.50 to $2 per gallon following geopolitical tensions has re-focused fleet operators on fuel cost stability, and RNG offers a domestically produced, less volatile alternative that leverages existing fueling infrastructure without sacrificing range or performance. While upfront tractor costs remain a barrier, the company’s strategy of targeting fleets where RNG delivers the clearest economic and low-carbon advantages—such as transit and refuse sectors with long-standing relationships—creates a foundation for incremental adoption that can scale as total cost of ownership calculations become more favorable. This approach avoids the pitfalls of broad, indiscriminate marketing and instead focuses on high-propensity customers, increasing the likelihood of successful conversion and repeat business. The underappreciated growth potential in these core segments, combined with the reliability of RNG as evidenced by firsthand fleet experience, suggests that adoption will accelerate not through sudden mass conversion but through sustained, relationship-driven expansion as fleets gain operational familiarity and validate the technology in real-world conditions.
The company’s upstream RNG production business is developing a significant competitive advantage through its portfolio of dairy-based projects with exceptionally low carbon intensity scores, exemplified by the CARB-approved Del Rio Dairy pathway at approximately negative 300, which nearly doubles the LCFS credit generation potential compared to standard negative 150 pathways. This regulatory milestone, coupled with the anticipated DOE GREET model update that will better reflect the negative carbon intensity of dairy RNG, positions Clean Energy Fuels Corp. to capture premium value in California’s LCFS market, where demand for low-carbon-intensity fuel remains strong and the company operates the largest RNG station network. The recent completion of the eighth dairy RNG facility at East Valley Cattle in Jerome, Idaho—one of the largest single-site dairies in North America—further scales this advantage, with the project already generating revenue and securing full EPA and CARB approvals for RIN and LCFS credit generation in Q1 2026. These projects are not only producing fuel but also creating a self-reinforcing cycle: low-carbon RNG generates higher-value environmental credits, which improve project economics and enable further investment in production capacity, thereby increasing fuel supply and strengthening the company’s integrated model across upstream production and downstream distribution.
Clean Energy Fuels Corp. is benefiting from a favorable commodity market dynamic where rising diesel prices have increased retail fuel revenues without a proportional increase in natural gas commodity costs, allowing the company to maintain a large discount to diesel while simultaneously boosting top-line revenue. This was evident in Q1 2026, where RNG volumes delivered reached 67.4 million gallons—up from 50.6 million in the prior year—and total revenue increased to $117.6 million from $103.8 million, driven by higher fuel volumes and optimized RIN and LCFS credit monetization. The company’s ability to monetize a larger-than-expected amount of RIN and LCFS credits from projects like the East Valley dairy in Idaho, even amid extreme winter weather impacting Upper Midwest production, demonstrates operational resilience and effective risk management. Furthermore, the non-GAAP financial picture shows improving core performance, with Adjusted EBITDA of $16.6 million in Q1 2026 closely matching the $17.1 million from the prior year despite lapping an easy comparison, and the 2026 outlook for Adjusted EBITDA ranging from $70 million to $75 million reflects confidence in sustained operational improvement as upstream projects ramp up and cost discipline is maintained. This underlying profitability, masked by GAAP losses due to non-cash charges like the Amazon warrant, indicates that the business is generating real cash flow from its integrated operations, which can be reinvested into growth initiatives or returned to shareholders as the company scales.

▼ Bear case

Clean Energy Fuels Corp. faces persistent structural challenges in the heavy-duty trucking market that are unlikely to be resolved by temporary diesel price spikes, as fleet adoption of RNG-powered vehicles remains constrained by high upfront costs, long sales cycles, and regulatory uncertainty—particularly in California—despite the economic advantages of lower total cost of ownership. Management acknowledged that even with favorable diesel economics, fleets are not making rapid conversions, instead opting for cautious, incremental adoption (e.g., starting with 5–10 trucks) to validate the technology, which prolongs the sales cycle and delays meaningful volume growth. This behavior is exacerbated by ESG whiplash and fluid sustainability policies, causing fleets to delay capital expenditures amid near-term stakeholder pressures, and the company’s reliance on the Cummins X15N engine—while technically viable—has seen slower-than-expected OEM adoption, limiting the addressable market for its fuel. The trucking segment, identified as the largest growth opportunity, remains hampered by these factors, and without a significant shift in fleet purchasing behavior or policy support, the company’s growth projections may be overly optimistic, especially given that Q1 2026’s strong RNG volume performance was partly attributed to an easy comparison against a depressed prior-year period due to biogas reform timing and widespread adverse weather.
The company’s upstream RNG production business continues to face operational and financial headwinds that are slowing project ramp-ups and undermining the expected returns from its dairy investments, despite recent regulatory approvals. Management admitted that projects have taken longer to develop and ramp up than initially expected, with some encountering operational challenges that required a more hands-on approach, internal oversight strengthening, and vendor replacements—processes that take time and delay cash flow generation. The Q1 2026 results showed a widened loss in the RNG upstream segment, with Adjusted EBITDA deteriorating from $(2.976) million to $(2.814) million, and extreme winter weather in the Upper Midwest further disrupted production, highlighting the geographic and climatic vulnerabilities of dairy-based RNG projects. While the East Valley and South Fork projects are ramping up, the company’s continued capital contributions—such as the $12 million Q1 2026 and another $12 million in April to the MAS Energy Works JV for three under-construction dairy projects—signal ongoing cash outflows without commensurate near-term returns, raising concerns about the pace and profitability of scaling this capital-intensive business model.
Clean Energy Fuels Corp.’s financial performance remains heavily distorted by non-cash, non-operational charges that obscure true profitability and create volatility in GAAP earnings, making it difficult for investors to assess the core business’s health and sustainability. The Amazon warrant charges, which totaled $10.1 million in Q1 2026 and are expected to reach approximately $47 million for the full year 2026, continue to weigh on both revenue and earnings, with management noting a change in how the charge is allocated between fuel sales and facility use fees—a shift driven contractually but not fully explained, suggesting potential complexity in the agreement that could have further implications. Additionally, the company’s reliance on non-GAAP metrics like Adjusted EBITDA to tell a positive story—while GAAP net loss remains significant at $(12.4) million for Q1 2026 and is projected to be $(66)–$(71) million for the full year—indicates that underlying profitability is still elusive when measured by standard accounting principles. This persistent gap between GAAP and non-GAAP results, coupled with ongoing losses from equity method investments and the need to add back substantial non-cash charges to reveal adjusted profitability, raises questions about whether the business can ever achieve sustainable GAAP profitability without fundamental changes to its cost structure or revenue mix, particularly as interest expenses and depreciation remain elevated.
