OPAL Fuels ("OPAL Fuels" or the "Company") (NASDAQ:OPAL) today announced financial and operating results for the three and nine months ended September 30, 2025.

"Third quarter results were in line with our expectations," said Adam Comora, Co-Chief Executive Officer of OPAL Fuels. "RNG production continues to increase, up 8% sequentially and 30% when compared to the third quarter of 2024. We are pleased operationally with the progress made in the third quarter and we expect full year results to be within our 2025 guidance range, despite a lower D3 RIN price environment. We continue to execute on our strategic growth objectives having placed our Atlantic RNG Project online last month and today announce our CMS RNG Project in North Carolina has entered construction representing 1.0 million MMBtu of annual design capacity net to OPAL Fuels. We continue to see a positive policy environment where RNG receives bipartisan support. In the quarter, we completed our fourth sale of IRA Investment Tax Credits with aggregate total gross sale proceeds greater than $40 million this year and expect to begin recognizing 45Z production tax credits in the fourth quarter."

"Our annual design capacity is now at 9.1 million MMBtu across twelve operating projects, our vertical integration with the marketing and distribution of RNG and CNG as a transportation fuel continues to contribute to our growth," said Co-Chief Executive Officer Jonathan Maurer. "We are building an energy infrastructure platform to address heavy-duty transportation, historically a hard to de-carbonize sector. At present, RNG and CNG are the most attractive alternatives to replace diesel for the Class 8 trucking market. We are positioned to lead faster adoption in this market which is building long-term and sustainable intrinsic value for OPAL shareholders."

Utilization of Inlet Gas (%) ⁽⁴⁾	77	%	84	%	76	%	82	%

⁽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:
