Material Changes vs. Prior Period
- Significant Net Loss Increase: The net loss widened significantly to $222.0 million from $83.1 million in 2024. This was primarily driven by a $64.3 million goodwill impairment charge recognized in Q1 2025 due to a sustained decline in stock price, and a $54.4 million charge for accelerated depreciation and asset retirement obligations related to the non-renewal of the Pilot Travel Centers agreement.
- Revenue Composition Shift: While total revenue increased slightly, the company lost a significant revenue stream from the Alternative Fuel Tax Credit (AFTC), which expired on December 31, 2024. AFTC revenue dropped from $23.8 million in 2024 to $0.2 million in 2025. This was partially offset by increased fuel sales volumes and higher station construction sales.
- Debt Reduction: The company voluntarily prepaid $65.0 million of its Stonepeak Term Loan principal in December 2025, reducing total principal debt from $300.0 million to $250.0 million. This action incurred a $11.5 million loss on extinguishment of debt.
- Asset Impairments: In addition to goodwill, the company recognized $54.4 million in charges related to the removal of equipment from Pilot Travel Centers stations following the expiration of their agreement.
Guidance, Outlook, and Risks
- Capital Expenditures: The company plans approximately $25.0 million in capital expenditures for 2026, primarily for fueling stations and IT. Additionally, it anticipates deploying up to $42.0 million to develop Anaerobic Digester Gas (ADG) RNG production facilities.
- Regulatory Risks: The company faces significant uncertainty regarding federal and state incentives. The "One Big Beautiful Bill Act" (OBBBA) signed in July 2025 modified tax incentives, including the Section 45Z clean fuel production credit. Furthermore, California's Advanced Clean Trucks (ACT) and Advanced Clean Fleets (ACF) regulations face legal challenges and potential repeal, which could impact the adoption of RNG vehicles.
- Operational Developments: The South Fork Dairy RNG project began operations in Q4 2025. The Pickens Plant in Texas resumed LNG production in January 2025 after major repairs. The company is also navigating bankruptcy proceedings for two dairy farm partners (East Valley and Ash Grove) involved in its bp Joint Venture projects.
- Market Risks: The company highlights volatility in Environmental Credit prices (RINs and LCFS) and the competitive pressure from diesel and electric vehicles. Adoption of heavy-duty natural gas trucks has been slower than anticipated.
Investor Verification Checklist
- Goodwill Impairment: Verify the assumptions used in the Q1 2025 goodwill impairment test, specifically the fair value calculation and the impact of the stock price decline.
- Regulatory Incentives: Assess the specific impact of the OBBBA and potential changes to California's ACT/ACF rules on future revenue from Environmental Credits and tax credits.
- Joint Venture Status: Monitor the resolution of the bankruptcy proceedings for the East Valley and Ash Grove dairy partners to ensure continued feedstock supply for the bpJV projects.
- Debt Covenants: Review the Stonepeak Credit Agreement covenants, particularly the leverage and interest coverage ratios, given the recent debt prepayment and ongoing losses.
- Pilot Agreement Impact: Confirm the long-term strategic impact of the Pilot Travel Centers contract expiration and the $54.4 million charge on future station construction and revenue.
