OPAL Fuels ("OPAL Fuels" or the "Company") (NASDAQ:OPAL) today announced financial and operating results for the three and six months ended June 30, 2026.

"Second quarter financial results were solid and in line with our expectations with adjusted EBITDA growth of 40% percent over the second quarter of last year," said Adam Comora, Co-Chief Executive Officer of OPAL Fuels. "Contribution from 45Z production tax credits, growth in our FSS segment, and G&A cost savings drove financial results in a flat RIN price environment versus last year. These results keep us on track to meet our annual guidance."

"We continue to pursue opportunities to drive increased production and EBITDA at our existing operating facilities, which require minimal capital investment. In addition, we are advancing the construction of new RNG facilities that will expand our production capacity as they come online," said Jonathan Maurer, Co-Chief Executive Officer of OPAL Fuels. "Longer term growth for OPAL Fuels is underpinned by the structural economic advantage of natural gas versus diesel. Our vertically integrated model allows us to capitalize on this opportunity."

Financial Highlights

Adjusted EBITDA⁽¹⁾ for the three and six months ended June 30, 2026, was $23.1 million and $39.8 million compared to $16.5 million and $36.6 million for the comparable periods last year an increase of 40% and 9% respectively.
Revenue for the three and six months ended June 30, 2026, was $83.4 million and $156.8 million respectively, an increase of 4% and a decrease of (5)% compared to the same periods last year.
Net (loss) income for the three and six months ended June 30, 2026 was $(4.1) million and $(9.7) million, compared to $7.6 million and $8.8 million in the same periods last year.
Basic and diluted net (loss) income per share attributable to Class A common shareholders for the three and six months ended June 30, 2026 were $(0.05) and $(0.14) compared to $0.03 and $0.02 in the comparable period last year.

Landfill RNG Facility Capacity and Utilization Summary

	Three Months Ended June 30,				Six Months Ended June 30,

Volume of Inlet Gas (Million MMBtus) ⁽²⁾	1.6		1.6		3.1		3.0
Inlet Design Capacity Utilization (%) ⁽²⁾	75.2	%	76.3	%	73.5	%	72.5	%
RNG Fuel volume produced (Million MMBtus)⁽³⁾	1.2		1.1		2.4		2.2
Utilization of Inlet Gas (%)⁽⁴⁾	76.6	%	75.0	%	76.0	%	75.8	%

⁽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. Excludes Sunoma and Biotown.
⁽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, RNG development costs, 45z generation 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:
