WHITE PLAINS, N.Y.--(BUSINESS WIRE)--Mar 16, 2026--

OPAL Fuels (“OPAL Fuels” or the “Company”) (Nasdaq: OPAL) today announced financial and operating results for the three and twelve months ended December 31, 2025.

"2025 was an important year for OPAL Fuels as we continue to scale our platform and prepare for additional growth," said Adam Comora, Co-Chief Executive Officer of OPAL Fuels. "Despite experiencing some regulatory and macro headwinds in 2025, we are pleased to have closed the year with Adjusted EBITDA of $90.2 million, within our guidance. Production increased to 4.9 million MMBtu, 28% higher compared to 2024, helped by improved operations during the second half of the year. We also sold $42.9 million of Investment Tax Credits and began recognizing our first 45Z production tax credits."

"We are encouraged by fourth quarter results. Adjusted EBITDA was $34.2 million as we benefited from increased production and 45Z production tax credits," continued Comora. "As we look to 2026, we are well positioned to drive continued RNG production growth from our existing facilities based on improvements in our team, in our gas collection, and in overall plant efficiencies. We are also optimistic about new CNG/RNG fleet adoption as downstream fundamentals continue to improve."

"We have improved our liquidity position which supports continued execution on our strategic growth plans," said Jonathan Maurer, Co-Chief Executive Officer of OPAL Fuels. "The recent refinancing of our existing Series A Preferred Units with a new upsized $180 million Series A Preferred Facility provides additional capital to invest across the RNG value chain.”

"As we have grown our upstream portfolio to 12 operating RNG facilities with 9.1 million MMBtu in annual design capacity, OPAL Fuels generates stable and growing operating cash flows to support long-term growth," continued Maurer. "These operating cash flows combined with our added liquidity provide us the opportunity to allocate capital in value enhancing opportunities as the macro and regulatory environment improves."

Financial Highlights

Revenue for the three and twelve months ended December 31, 2025, was $99.8 million and $349.0 million respectively, an increase of 25% and 16% respectively, compared to the prior-year period.
Net Income (loss) for the three and twelve months ended December 31, 2025, was $16.2 million and $36.4 million respectively, compared to $(5.4) million and $14.3 million in the same periods last year.
Basic and diluted net income per share attributable to Class A common shareholders for the three and twelve months ended December 31, 2025 were $0.02 and $0.15 compared to $(0.05) and $0.02 in the comparable periods last year.
Adjusted EBITDA 1 for the three and twelve months ended December 31, 2025, was $34.2 million and $90.2 million respectively, compared to $22.6 million 2 and $90.0 million 2 respectively, in the comparable periods last year.
$42.9 million of IRA Investment Tax Credits were sold in 2025.
In March 2026 we closed a new $180 million preferred stock facility with an affiliate of our majority shareholder, Fortistar. $120 million was issued from the facility at closing, of which approximately $100 million was used to fully redeem the Series A Preferred Units previously owned by Mendocino Capital, LLC. The remaining $60 million of the facility to be available for future draw-downs.

Landfill RNG Facility Capacity and Utilization Summary

	Three Months Ended December 31,	Year Ended December 31,
	2025	2024	2025	2024
Landfill RNG Facility Capacity and Utilization
Design Capacity (Million MMBtus) (1)	2.2		2.1		8.6		6.6
Volume of Inlet Gas (Million MMBtus) (2)	1.6		1.3		6.2		4.6
Inlet Design Capacity Utilization (%) (2)	76	%	67	%	75	%	73	%
RNG Fuel volume produced (Million MMBtus) (3)	1.3		1.1		4.7		3.7
Utilization of Inlet Gas (%) (4)	80	%	78	%	77	%	81	%

(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 gas collection system used to recover the landfill gas. The Design Capacity for each facility will typically be correlated to the amount of landfill 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. Excludes Sunoma and Biotown. (3) Excludes Sunoma and Biotown (4) 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%. Excludes Sunoma and Biotown.

Non-GAAP Financial Measures (Unaudited)

This release includes various financial measures that are non-GAAP financial measures as defined under the rules of the Securities and Exchange Commission. We believe these measures provide important supplemental information to investors to use in evaluating ongoing operating results. We use these measures, together with accounting principles generally accepted in the United States ("GAAP" or "U.S. GAAP"), for internal managerial purposes and as a means to evaluate period-to-period comparisons. However, we do not, and you should not, rely on non-GAAP financial measures alone as measures of our performance. We believe that non-GAAP financial measures reflect an additional way of viewing aspects of our operations, that when taken together with GAAP results and the reconciliations to corresponding GAAP financial measures that we also provide, give a more complete understanding of factors and trends affecting our business. We strongly encourage you to review all of our financial statements and publicly filed reports in their entirety and to not solely rely on any single non-GAAP financial measure.

Non-GAAP financial measures are limited as an analytical tool and should not be considered in isolation from, or as a substitute for, the Company's GAAP results. The Company expects to continue reporting non-GAAP financial measures, adjusting for the items described below (and/or other items that may arise in the future as the Company's management deems appropriate), and the Company expects to continue to incur expenses, charges or gains like the non-GAAP adjustments described below. Accordingly, unless expressly stated otherwise, the exclusion of these and other similar items in the presentation of non-GAAP financial measures should not be construed as an inference that these costs are unusual, infrequent, or non-recurring. These Non-GAAP financial measures are not recognized terms under GAAP and do not purport to be alternatives to GAAP net income or any other GAAP measure as indicators of operating performance. Moreover, because not all companies use identical measures and calculations, the Company's presentation of Non-GAAP financial measures may not be comparable to other similarly titled measures used by other companies. We strongly encourage you to review all of our financial statements and publicly filed reports in their entirety and to not solely rely on any single non-GAAP financial measure.

Adjusted EBITDA

To supplement the Company's unaudited condensed consolidated financial statements presented in accordance with GAAP, the Company uses a non-GAAP financial measure that it calls Adjusted EBITDA ("Adjusted EBITDA"). This non-GAAP financial measure adjusts net income for interest and financing expense, net, net income attributable to non-redeemable non-controlling interests, depreciation, amortization and accretion, adjustments to reflect Adjusted EBITDA from equity method investments, fair value changes and non-recurring charges, Stock-based compensation, major maintenance on Renewable Power, RNG development costs, and ITC proceeds, net.

Management believes this non-GAAP financial measure provides meaningful supplemental information about the Company's performance, for the following reasons: (1) it allows for greater transparency with respect to key metrics used by management to assess the Company's operating performance and make financial and operational decisions; (2) the measure excludes the effect of items that management believes are not directly attributable to the Company's core operating performance and may obscure trends in the business; (3) the measure better aligns revenues with expenses; and (4) the measure is used by institutional investors and the analyst community to help analyze the Company's business. In future quarters, the Company may adjust for other expenditures, charges or gains to present non-GAAP financial measures that the Company's management believes are indicative of the Company's core operating performance.

The following table presents the reconciliation of our net income to Adjusted EBITDA:
