Clean Energy Fuels’ latest earnings call struck a cautiously optimistic tone as management balanced solid execution with lingering headwinds. Adjusted EBITDA beat guidance, RNG volumes scaled close to plan, and debt paydown strengthened the balance sheet, while 2026 guidance pointed to continued growth. Still, sizable GAAP losses, policy and market risks, and slower truck adoption tempered the bullish narrative.
Adjusted EBITDA Beat and Evolving Financial Profile
Clean Energy Fuels reported 2025 adjusted EBITDA of $67.6 million, roughly 4% above the top end of guidance and a key bright spot for investors focused on cash performance. For 2026, the company projects adjusted EBITDA of $70 million to $75 million on revenues of $420 million to $440 million, signaling modest but steady expansion even as tax credits roll off.
Debt Reduction Strengthens Liquidity and Lowers Interest
The company repaid $65 million of debt in Q4 2025, cutting leverage and positioning itself for roughly $6 million less interest expense in 2026. It ended 2025 with $156.1 million of cash and investments and does not expect to tap new borrowings this year, underscoring a more self-funded growth model.
RNG Volumes Near Target With Growth Ahead
RNG deliveries reached 237.4 million gallons in 2025, or about 97% of the company’s target, with Q4 volumes of 64.1 million gallons up 5% sequentially and 3% year over year. Management’s 2026 outlook calls for roughly 250 million gallons of RNG and about 324 million total fuel gallons, reinforcing a gradual but sustained volume growth trajectory.
Large Upstream Projects Anchor Growth Platform
On the project side, Clean Energy brought South Fork Dairy in Texas fully online as its largest consolidated RNG asset, while East Valley Dairy in Idaho began gas injection and stands as its largest overall RNG project via a joint venture. Across the portfolio, the company now counts eight operating RNG projects and three more under construction through Moss Energy Works.
Commercial Wins Boost Downstream and RNG Penetration
Downstream, the company renewed and expanded key contracts, notably with WM for 85 stations fueling about 8,000 refuse trucks, alongside municipal wins in Scottsdale, Phoenix, Washington, D.C., Nashville, Arlington and Fort Smith. Around 89% of company-controlled fueling infrastructure now dispenses RNG, signaling deepening penetration of its low-carbon fuel.
Upstream Business Moving Toward Profitability
Management emphasized that RNG upstream operations, which have historically generated GAAP losses, should show significant improvement in 2026. They expect the upstream segment to deliver positive adjusted EBITDA next year, targeting roughly $3 million to $5 million as new facilities ramp and existing dairies optimize output.
Cost Controls and Capital Discipline Take Center Stage
To support profitability, SG&A is expected to fall about 10% in 2026, more than $10 million, to an approximate run rate of $25 million per quarter. Planned capital spending totals about $25 million for fuel distribution and $40 million for RNG upstream, all intended to be funded from existing cash and roughly $50 million of projected operating cash flow.
Policy Environment Turning More Supportive
Management highlighted improving signals in low-carbon fuel markets, pointing to a Q3 2025 CARB report showing the first LCFS net deficit since 2021 as constructive for credit pricing. They also cited progress on the 45Z clean fuel production credit rulemaking, which could enhance project economics once finalized and implemented.
GAAP Losses Still Heavy Despite Cash Progress
Despite the adjusted EBITDA beat, the company posted a 2025 GAAP net loss of $222 million, slightly worse than anticipated and largely tied to non-cash interest charges from debt paydown and loan expiration. For 2026, management still guides to a GAAP net loss of $71 million to $66 million, reminding investors that accounting losses will lag underlying cash improvements.
Weather-Related Volume Shortfall Highlights Operational Risk
RNG production landed just shy of target primarily because extreme weather in Q1 2025 disrupted some third-party RNG supply flows. Management said these weather-related issues have eased but acknowledged that operating risk from severe conditions remains an ongoing factor for RNG production.
Heavy-Duty Truck Adoption Slower Than Hoped
The roll-out of Cummins’ X15N natural gas engine and associated heavy-duty truck purchases came in slower during 2025, pressured by a weak freight market that delayed fleet replacement cycles. That drag pushed out some conversions to RNG-powered trucks, muting near-term demand upside even as long-term interest remains.
One-Time SG&A Costs Inflate Q4 Expense Base
Fourth-quarter SG&A ran about $4 million higher than the normal run rate due to one-off personnel-related and station exit costs. While these elevated expenses weighed on near-term profitability, management framed them as non-recurring and pointed to planned SG&A reductions for 2026.
Competitive Pressure on Credits and Margins
Some major contract renewals required Clean Energy to give up a larger share of environmental credits, reflecting intensified competition in RNG fuel supply. Management expects fuel distribution adjusted EBITDA to step down from strong 2025 levels, though they still characterize margin levels as adequate for the business.
Tax Credit Expiration Skews Year-Over-Year Comparisons
Comparisons to 2024 are complicated by the expiration of the alternative fuel tax credit at year-end 2024, which had boosted 2024 EBITDA by about $24 million, including roughly $6 million in Q4. With that credit gone, 2025 revenues and adjusted EBITDA look weaker on paper than they would if the incentive still applied.
Market Risk From Potential Fuel Spread Tightening
Management remains wary of the natural gas-to-oil price spread, noting that any sustained narrowing would lengthen payback periods for RNG trucks. If that trend persists, it could slow future RNG adoption by reducing the economic advantage fleets realize from switching away from diesel.
Forward-Looking Guidance Emphasizes Gradual Growth and Self-Funding
Looking ahead to 2026, Clean Energy expects adjusted EBITDA of $70 million to $75 million, revenues between $420 million and $440 million and a GAAP net loss of $71 million to $66 million. With RNG volumes guided to 250 million gallons, eight operating dairies plus three under construction and no new borrowings planned, management is pitching a story of measured volume growth, improving upstream profitability and tighter cost control supported by a solid liquidity cushion.
Overall, the earnings call portrayed a company transitioning from subsidy-boosted growth toward a more self-sustaining RNG platform anchored by major dairy projects and expanding fleet relationships. While accounting losses, policy volatility and adoption risks persist, Clean Energy Fuels’ execution on volumes, debt reduction and disciplined spending offered investors a cautiously constructive outlook for 2026.
