Insights

Renewable energy financials analyst

Mixed quarter: stable revenue, margin pressure, strong cash flow.

OPAL Fuels kept revenue broadly flat in Q3 at $83.4M while operating income fell to $3.6M, reflecting softer RNG Fuel and Renewable Power contributions and environmental credit write‑downs. Fuel Station Services remained the growth engine at $51.7M.

Net income of $11.4M benefited from a sizeable income tax benefit of $14.6M, masking weaker operating leverage. Year‑to‑date, operating cash flow improved to $40.0M, supporting liquidity as the OPAL Term Loan rose to $313.3M.

Key dependencies include environmental credit pricing (with Q3 and year‑to‑date write‑downs of $4.5M and $15.1M) and execution of the $51.5M Fuel Station Services backlog. Subsequent filings may provide additional detail on project timing and segment margins.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, that involve risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations or financial condition, business strategy and plans and objectives of management for future operations, are forward-looking statements.

These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside our control, which could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Important factors, among others, which may affect actual results or outcomes include:

▪our ability to grow and manage growth profitably, and maintain relationships with customers and suppliers;

▪our success in retaining or recruiting, our principal officers, key employees or directors;

▪intense competition and competitive pressures from other companies in the industry in which we operate;

▪increased costs of, or delays in obtaining, key components or labor for the construction and completion of LFG (as defined below) and livestock waste projects that generate electricity and RNG (as defined below), CNG (as defined below) and hydrogen dispensing stations;

▪factors relating to our business, operations and financial performance, including market conditions and global and economic factors beyond our control;

▪the reduction or elimination of government economic incentives to the renewable energy market;

▪factors associated with companies that are engaged in the production and integration of RNG, including (i) anticipated trends, growth rates and challenges in those businesses and in the markets in which they operate, (ii) contractual arrangements with, and the cooperation of, owners and operators of the landfill and livestock biogas conversion project facilities, on which we operate our LFG and livestock waste projects that generate electricity and (iii) RNG prices for Environmental Attributes (as defined below), LCFS (as defined below) credits and other incentives;

▪the ability to identify, acquire, develop and operate renewable projects and Fueling Stations (as defined below);

▪our ability to issue equity or equity-linked securities or obtain or amend debt financing;

▪the demand for renewable energy not being sustained;

▪impacts of climate change, changing weather patterns and conditions and natural disasters; and

▪the effect of legal, tax and regulatory changes.

The forward-looking statements contained in this Form 10-Q are based on current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described under the heading “Risk Factors” in this Form 10-Q and in our Annual Report on Form 10-K, which was filed with the SEC on March 17, 2025 (our "Annual Report"). Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

At the Fueling Stations, the natural gas is pressurized using compressor systems and, in this state, is referred to as CNG. Because Environmental Attributes associated with RNG are nominated/assigned to the physical quantity of CNG dispensed at the Fueling Station, when the CNG is dispensed into to fuel tanks for use as transportation fuel and subsequently reported to the EPA and/or state environmental agency and matched with the production of RNG, the respective RINs and LCFS credits are generated.

1. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of OPAL Fuels, Inc. and its subsidiaries (the “Company”, “OPAL Fuels”, “we,” “us” or “our”) and reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results of operations for the interim period. In addition, we have consolidated the financial results of jointly owned affiliated companies in which our principal stockholder or other entities have a noncontrolling interest. All intercompany transactions and balances have been eliminated in consolidation. The non-controlling interest attributable to the Company's variable interest entities ("VIE") are presented as a separate component from the Stockholders' equity (deficit) in the condensed consolidated balance sheets and as a non-redeemable non-controlling interest in the condensed consolidated statements of changes in redeemable non-controlling interests, redeemable preferred non-controlling interests and stockholders' equity (deficit).

As of September 30, 2025, the Company held equity interests in twelve VIEs — Pine Bend RNG LLC ("Pine Bend"), Noble Road RNG LLC ("Noble Road"), Paragon RNG LLC ("Paragon"), Emerald RNG LLC ("Emerald") - Paragon project, Sapphire RNG LLC ("Sapphire") - Paragon project, Land2Gas LLC ("Land2Gas"), Atlantic RNG LLC ("Atlantic") - Land2Gas project, Burlington RNG LLC ("Burlington") - Land2Gas project, GREP BTB Holdings LLC ("GREP"), Sunoma Holdings, LLC (“Sunoma”), Central Valley LLC (“Central Valley”), and CMS RNG LLC ("CMS"). Pine Bend, Noble Road GREP, Paragon projects, Land2Gas projects were presented as equity method investments and the remaining three VIEs — Sunoma, Central Valley, and CMS are consolidated by the Company.

On May 9, 2025, the Company acquired a variable interest in CMS, a joint venture formed with a third party to develop, construct, own, and operate a renewable natural gas facility. The Company holds a 70% membership interest in CMS RNG, and the remaining 30% is held by the third-party partner.

Based on an evaluation under ASC 810, Consolidation ("ASC 810"), management determined that CMS RNG is a VIE and that the Company is the primary beneficiary. This conclusion is based on the Company’s power to direct the activities that most significantly impact CMS RNG’s economic performance and its exposure to the entity’s residual returns. As a result, CMS RNG has been consolidated in the Company’s financial statements beginning in the second quarter of 2025.

At the time of formation of CMS RNG, the Company and the third-party partner made net capital contributions of $4,646 and $1,998, respectively. A noncontrolling interest ("NCI") of $1,998 was recognized for the portion of CMS RNG not owned by the Company.

The Company will reassess its primary beneficiary conclusion on an ongoing basis, including upon execution of additional agreements and commencement of commercial operations.

The condensed consolidated balance sheets summarize the major consolidated balance sheet items for consolidated VIEs as of September 30, 2025 and December 31, 2024. The information is presented on an aggregate basis based on similar risk and reward characteristics and the nature of our involvement with the VIEs, such as:

•All of the VIEs are RNG facilities and they are reported under the RNG Fuel Supply segment;

•The nature of our interest in these entities is primarily equity based and therefore carry similar risk and reward characteristics.

The 2024 year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP"). The interim financial information and notes thereto should be read in conjunction with the Company's latest Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the "Annual Report") as the interim disclosures generally do not repeat those in the annual financial statements and are condensed in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. The results of operations for the three and nine months ended September 30, 2025, are not necessarily indicative of results to be expected for the entire fiscal year.

The Company is organized into three operating segments which are RNG Fuel, Fuel Station Services and Renewable Power.

All amounts in these footnotes are presented in thousands of dollars except share and per share data.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The significant estimates and assumptions of the Company include the residual value of the useful lives of our property, plant and equipment, the fair value of long-lived assets, the fair value of stock-based compensation, asset retirement obligations, percentage completion for revenue recognition, incremental borrowing rate for calculating the right-of-use lease assets and lease liabilities, the fair value of the reporting units of goodwill and the fair value of derivative instruments. Actual results could differ from those estimates.

The results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for the entire year.

The Company provides all third-party construction contracts with a warranty, typically for a period of one year after substantial completion of the construction project. These warranties are accounted for under ASC 460, Guarantees ("ASC 460"), and not as a separate performance obligation. Generally, the company estimates warranty costs based on historical claims experience, and other factors. Actual warranty claims may differ from the estimates, and adjustments to the liability are made, as necessary. The Company accrued $280 and $171 of warranty reserves under accrued expenses and other current liabilities as of September 30, 2025, and December 31, 2024, respectively.

Related Party Revenues

The Company revised its disclosure of Fuel Station Services revenues from related parties included parenthetically on the face of the condensed consolidated statements of operations to include amounts that were previously excluded. The amounts are immaterial and the revision had no impact on previously reported net income, cash flows, or financial position.

Accounting Pronouncements Adopted

In August 2023, the FASB issued Accounting Standards Update No. 2023-05, Business Combinations- Joint Venture Formations (Subtopic 805-60) ("ASU 2023-05"). The update requires all joint ventures formed after January 1, 2025, upon formation, to apply a new basis of accounting and initially measure its assets and liabilities at fair value. ASU 2023-05 is effective prospectively for joint ventures with a formation date on or after January 1, 2025. During the nine months ended September 30, 2025, the Company formed a joint venture that was excluded from this guidance due to the scope exception applicable to combinations between entities, businesses, or nonprofit activities under common control. The adoption did not have a material effect on the Company’s financial position, results of operations, cash flows or disclosures.

Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures. The amendments further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments require disclosure of specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures and the Company believes the adoption will not have a material effect on our condensed consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional, disaggregated disclosure about certain income statement line items. The ASU is effective for fiscal years beginning after December 15, 2026, and is required to be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact that this guidance will have on the disclosures within our condensed consolidated financial statements.

11

In July 2025, the Financial Accounting Standards Board (“FASB”) issued ASU 2025‑05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments provide a practical expedient applicable to all entities for estimating expected credit losses on current accounts receivable and current contract assets that arise under ASC 606, permitting the assumption that existing conditions at the balance‑sheet date will remain unchanged over the remaining life of such assets. The amendments are effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within our condensed consolidated financial statements.

In September 2025, the FASB issued ASU 2025‑06, Intangibles — Goodwill and Other (Topic 350): Internal‑Use Software — Targeted Improvements to the Accounting for Internal‑Use Software. The amendments modernize the guidance for capitalizing costs of internally‑developed software by removing references to defined development stages and instead focusing on two principal criteria: (1) management has authorized and committed to funding the project, and (2) it is probable that the project will be completed and the software will be used to perform the intended function. The ASU is effective for fiscal years beginning after December 15, 2027, including interim periods within those years, with early adoption permitted. The Company is currently evaluating the impact that this guidance will have on the disclosures within our condensed consolidated financial statements.

Earnout Liabilities

In connection with the Business Combination completed in July 2022 and pursuant to a sponsor letter agreement, ArcLight CTC Holdings II, L.P. agreed to subject 10% of its Class A common stock (received as a result of the conversion of its ArcLight Class B ordinary shares immediately prior to the closing) to vesting and forfeiture conditions relating to VWAP targets for the Company's Class A common stock sustained over a period of 60 months following the closing. As of September 30, 2025 and December 31, 2024, the number of shares subject to forfeiture was 716,650 (the "Sponsor Earnout Awards").

For the three and nine months ended September 30, 2025 the Company recorded a gain from the Sponsor Earnout Awards of $— and $281, respectively, in its condensed consolidated statements of operations. For the three and nine months ended September 30, 2024, the Company recorded a gain of $278 and $1,457, respectively, in its condensed consolidated statements of operations. As of September 30, 2025 and December 31, 2024, the Company recorded a Sponsor Earnout liability of $23 and $304, respectively, as part of other long-term liabilities on its condensed consolidated balance sheets.

Redeemable non-controlling interests

Redeemable non-controlling interests represent the portion of the Company's consolidated subsidiary OPAL Fuels LLC, that the Company does not own. The Redeemable non-controlling interest represents 144,399,037 Class B and D Units issued by OPAL Fuels to the prior investors. The Company allocates net income or loss attributable to Redeemable non-controlling interest based on weighted average ownership interest during the period. The net income or loss attributable to Redeemable non-controlling interests is reflected in the condensed consolidated statements of operations.

At each balance sheet date, the mezzanine equity classified Redeemable non-controlling interests is adjusted up to their maximum redemption value if necessary, with an offset in Stockholders' equity (deficit). As of September 30, 2025, the maximum redemption value was $342,528.

Parts Inventory

Parts inventory, also referred to as supplies inventory, consists of shop spare parts inventory and construction site parts inventory. The substantial amount of inventory is identified, tracked and treated as finished goods.

Amended OPAL Term Loan and Revolving Loan

On March 3, 2025, OPAL Fuels Intermediate HoldCo LLC, as the borrower (the “Borrower”), certain subsidiaries of the Borrower, as guarantors (the “Guarantors”), the lenders and issuers of letters of credit party thereto and Bank of America, N.A. as the administrative agent (the “Administrative Agent”) entered into that certain Amendment No. 1 to Credit and Guarantee Agreement (the “Credit Agreement Amendment”), with respect to that certain Credit and Guarantee Agreement (the “Credit Agreement”) dated September 1, 2023, by and among the Borrower, the Administrative Agent, the financial institutions from time to time parties thereto as lenders and as issuers of letters of credit, and the other agents and persons from time to time party thereto (as amended, restated, amended and restated, supplemented or otherwise modified and in effect from time to time).

16

The Credit Agreement Amendment makes certain changes to the applicability of certain financial covenants and modifies other covenants to clarify the use of loan proceeds. Additionally, the Credit Agreement Amendment permits the organizational restructuring of the Guarantors in a manner designed to facilitate the sale of federal investment tax credits and the ability to raise additional future capital.

The Credit Agreement Amendment also eases the conditions precedent to making new Projects eligible for borrowing under the Credit Agreement, extends the availability period for delay draw term loans under the Credit Agreement through March 5, 2026, and extends the commencement of repayment of such term loans until March 31, 2026. The Amendment was accounted for as a modification in the nine month period ended September 30, 2025.

In connection with the Credit Agreement Amendment, the Borrower paid the Administrative Agent, for the account of each lender, a one-time nonrefundable fee of $1,250. These costs have been recorded as a direct reduction against the debt and amortized over the life of the associated debt as a component of interest expense using the effective interest method.

During the nine months ended September 30, 2025, the Company borrowed $40,000 under its term loan, drew $20,000 from its revolving loan and repaid $15,000 on its revolving loan. As of September 30, 2025, the Company utilized $34,517 of availability under the revolver loan to provide for the issuance of letters of credit to support the operations of the Borrower and the Guarantors.

The Company has the ability, during the delayed draw availability period and subject to the satisfaction of certain credit and project-related conditions precedent, to join other newly acquired subsidiaries with comparable renewable projects in development under the credit facility for comparable funding. As of September 30, 2025, the Company is in compliance with the financial covenants under the OPAL Term Loan. The amounts outstanding under the Credit Agreement are secured by the assets of the indirect subsidiaries of OPAL Intermediate Holdco.

Sunoma Loan

On August 27, 2020, Sunoma, an indirect wholly-owned subsidiary of the Company entered into a debt agreement (the "Sunoma Loan Agreement") with Live Oak Banking Company for an aggregate principal amount of $20,000 that was increased to $23,000 in 2022. As of September 30, 2025, Sunoma is in compliance with the financial covenants under the Sunoma Loan Agreement.

The Company also utilized $968 for the issuance of letters of credit to support the operations of the Borrower. The amounts outstanding under the Sunoma Loan are secured by the assets of Sunoma.

2025

For the three and nine months ended September 30, 2025, the weighted average effective interest rate including amortization of debt issuance costs on OPAL Term Loan was 8.8% and 8.5% respectively. For the three and nine months ended September 30, 2025, the interest rate on the Sunoma Loan was 8.7%.

			$	—		$	278		$	281		$	1,457		Change in fair value of derivative instruments, net

Fair value measurements

The carrying amount of cash and cash equivalents, accounts receivable, net, and accounts payable and accrued expenses approximates fair value due to their short-term maturities.

The carrying value of the Company's long-term debt, classified as Level 2 within the fair value hierarchy, approximates its fair value as of as of September 30, 2025 and December 31, 2024, because the interest rates are variable and therefore reflect current market conditions.

The Company accounts for asset retirement obligations by recording the fair value of a liability for an asset retirement obligation in the period in which it is incurred and when a reasonable estimate of fair value can be made. The Company estimated the fair value of its asset retirement obligations based on discount rates ranging from 5.8% to 8.5%.

The fair value of the Sponsor Earnout Awards as of September 30, 2025 was determined using a Black-Scholes valuation model with a distribution of potential outcomes on a daily basis over the 2.0 years remaining in the vesting window. Assumptions used in the valuation are as follows:

•Current stock price — The Company's closing stock price of $2.20 as of September 30, 2025;

•Expected volatility —50% based on historical and implied volatilities of selected industry peers deemed to be comparable to our business corresponding to the expected term of the awards;

20

•Risk-free interest rate — 3.6% based on the U.S. Treasury yield curve in effect at the time of issuance for zero-coupon U.S. Treasury notes with maturities corresponding to the expected 1.8 year term of the earnout period;

•Dividend yield - zero.

Convertible note receivable

In July 2024, the Company purchased a convertible note pursuant to which the Company has the right to convert the note into shares of Class A common stock of the investee for $750. In the third quarter of 2025, the investee underwent an exit event, resulting in the note settlement. The Company received $1,377 in cash proceeds, with an additional $198 remaining in escrow recorded under prepaid expense and other current assets.

There were no transfers of assets between Level 1, Level 2, or Level 3 of the fair value hierarchy as of September 30, 2025.

The Company's assets and liabilities that are measured at fair value on a recurring basis include the following as of September 30, 2025 and December 31, 2024, set forth by level, within the fair value hierarchy:

Purchase and sale agreement for environmental attributes

21

In January 2025, the EPA implemented a new framework in which (1) RNG producers are eligible to claim a “K-1” RINs on their volumes of RNG produced, and (2) dispensers are eligible to claim “K-2” RINs on natural gas volumes dispensed as truck fuel, provided they also have a corresponding K-1 RIN to demonstrate the renewable sourcing of gas. The creation of distinct “K-1” and “K-2” RINs creates flexibility for RNG producers to generate and sell K-1 RINs to dispensers independent of the K-2 registration process or dispensing activities. K-1 RINs are only useful for the purpose of registering a K-2 RIN, and K-2 RINs are used to record the environmental offset (similar to a traditional RIN). The introduction of K-1 and K-2 RINs gives rise to a new form of commercial transaction for Opal that is distinct from previous RIN minting arrangements.

On March 26, 2025, the Company entered into a NAESB Base Contract with NextEra (together with certain special conditions, a letter agreement, and an RNG addendum, the "NAESB Contract"). In accordance with the NAESB Contract, the Company could enter into transaction confirmations on a periodic basis for the sale of RNG generated by the RNG Fuels business and NextEra could elect to utilize the Company to market such RNG to generate RINs for NextEra. In March, June and September 2025, the Company and NextEra entered into such transaction confirmations.

The Company concluded that production and dispensing services represent separate performance obligations. Control over K-1 RINs transfers at the time of gas generation or upon delivery of the RINs. Revenue is recognized at the time control is transferred. The consideration associated with dispensing services is recognized into revenue by the Company when it satisfies its performance obligation by pairing the paperwork associated with the dispensing.

For the three and nine months ended September 30, 2025, the Company recognized revenues of $4,982 and $15,585, respectively, under the NAESB contract, which were recorded as part of Revenues - RNG Fuel.

Service agreements with related parties

On March 17, 2025, Fortistar, through its subsidiary Wasatch RNG LLC (“Wasatch RNG”), acquired all of the limited liability company interests outstanding in Alpro SD, LLC (“Alpro” and such acquired interest, the “Alpro Interest”). Alpro owns a 50% limited liability company interest in Wasatch Resource Recovery, LLC (the “Project” or “Wasatch” and such ownership interest, the “Wasatch Interest”) and a 50% tenancy-in-common interest in certain real estate and operating assets used by Wasatch (the “Project Interest”). The Project captures and converts biogas generated from food waste to produce pipeline quality RNG. The Project generates revenue from long-term contracted gas sales, tipping fees, and digestate (fertilizer) sales.

In connection with the acquisition, Fortistar Services 2 LLC and OPAL Fuels LLC entered into an amendment to its existing Administrative Services Agreement, pursuant to which OPAL Fuels will provide certain services to Wasatch RNG in exchange for certain agreed upon fees and expense reimbursements. These services include oversight of the plan to improve the operations and productivity of the Project. Either party may, at its sole election and on ninety (90) days advance written notice, terminate Company's provision of services to Wasatch, at which time the Management Fee and the Wasatch Remediation Fee shall also terminate.

Additionally, Wasatch RNG and OPAL Fuels entered into an Option Agreement, pursuant to which Wasatch RNG granted an option to OPAL Fuels to purchase the Alpro Interest. The exercise period of the option commenced upon closing of the acquisition and will terminate on the third anniversary of the closing of the acquisition, or ninety (90) days following a change of control of OPAL Fuels. The exercise price of the option would be determined such that Wasatch RNG would earn an internal rate of return on its invested capital of 10% percent per year if the option is exercised in the first year, 15% per year if exercised in the second year, and 20% per year if exercised in the third year.

Wasatch RNG is determined to be a VIE due to their having insufficient equity investment at risk to finance their activities without additional subordinated financial support, and due to the fact that the holder of equity at risk in Wasatch RNG lacks the right to fully receive the expected residual returns. However, we are not the primary beneficiary of this VIE because we do not have the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance. Accordingly, we do not consolidate the results of operations, financial condition and cash flows of Wasatch RNG in our condensed consolidated financial statements.

During the first quarter of 2025, Scott Contino, CFO of Fortistar, served as Interim CFO of the Company. Pursuant to the Interim Services Agreement, the Company paid Fortistar an agreed hourly rate, such that the monthly fee did not exceed $50, on a cumulative basis.

Class D Common Stock Conversion

On April 23, 2025, our ultimate controlling shareholder, Fortistar, through its subsidiary OPAL Holdco LLC, exchanged 50 million shares of Class D common stock of the Company held by it, each of which is entitled to five votes per share on all matters on which stockholders generally are entitled to vote, for an equal number of shares of newly issued Class B common stock of the Company, each of which is entitled to one vote on such matters. This transaction had no effect on the economic interest in the Company held by Fortistar.

7. Reportable Segments and Geographic Information

The Company is organized into three operating segments based on the characteristics of its renewable power generation, dispensing portfolio, production and sale of renewable gas, and nature of other products and services.

Our reportable segments disclosure is aligned with the information and internal reporting provided to our CODM. Our Co-CEOs, Adam Comora and Jonathan Maurer, jointly fulfill the role of the CODM. The CODM evaluates performance based on segment net income (loss). For all of the segments, the CODM uses segment net income (loss) in the annual budgeting and monthly forecasting process. The CODM considers budget-to-current forecast and prior forecast-to-current forecast variances for segment net income (loss) on a monthly basis for evaluating performance of each segment and making decisions about allocating capital and other resources to each segment.

The three operating segments are RNG Fuel, Fuel Station Services and Renewable Power. The Company has determined that each of the three operating segments meets the characteristics of a reportable segment under U.S. GAAP.

The Corporate entity is not determined to be an operating segment but is discretely disclosed for purposes of reconciliation of the Company’s consolidated financial statements, and though not denoted as an operating segment, significant expenses are noted within the segment.

The following table reflects the financial data used to calculate each reportable segment’s net income (loss) and includes reconciliations to Opal’s consolidated revenue and consolidated net income (loss) for the three and nine months ended September 30, 2025:

10. Income taxes

For the three and nine months ended September 30, 2025, the Company recorded $14,567 and $36,290 income tax benefit, respectively, as a result of the sale to a third-party purchaser of certain transferable Investment Tax Credits that had been generated by the Company from its investments in the RNG segment. For the three and nine months ended September 30, 2024, the Company recorded $8,906 income tax benefit. The effective tax rate for the three and nine months ended September 30, 2025 and 2024 was 0%. The difference between the Company’s effective tax rate and the U.S. statutory tax rate of 21% was primarily due to a full valuation allowance recorded on the Company’s net U.S. deferred tax assets. The Company evaluates the realizability of the deferred tax assets on a quarterly basis and establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset may not be realized.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law in the U.S. The OBBBA does not have a material effect on our condensed consolidated financial statements.

Legal Matters

The Company is involved in various claims arising in the normal course of business. Management believes that the outcome of these claims will not have a material adverse effect on the Company's financial position, results of operations or cash flows.

Set forth below is information related to the Company’s material pending legal proceedings as of the date of this report, other than ordinary routine litigation incidental to the business. There have been no material changes to such legal proceedings from the previous quarter.

Central Valley Project

In September 2021, an indirect subsidiary of the Company, MD Digester, LLC (“MD”), entered into a fixed-price Engineering, Procurement and Construction Contract (an “EPC Contract”) with VEC Partners, Inc. d/b/a CEI Builders (“CEI”) for the design and construction of a turn-key renewable natural gas production facility using dairy cow manure as feedstock in California’s Central Valley. In December 2021, a second indirect subsidiary of the Company, VS Digester, LLC (“VS”) entered into a nearly identical EPC Contract (collectively, the "EPC Contracts") with CEI for the design and construction of a second facility, also in California’s Central Valley. CEI’s performance under both of the EPC Contracts is fully bonded by licensed sureties.

CEI submitted a series of change order requests seeking to increase the EPC Contract Price by approximately $14 million, per project, primarily due to: (1) modifications to CEI’s design drawings which are required to meet its contracted performance guaranties, and (2) a default by one of CEI’s major equipment manufacturers. The Company disputes the vast majority of the change order requests.

In January 2024, the Company filed a civil lawsuit captioned, MD Digester, LLC. et. al. vs. VEC Partners, Inc. et. al.; with the California Superior Court, County of San Joaquin; Action No. STK- CV-UCC-2024-0000185 and commenced a related arbitration proceeding in order to obtain a formal determination on the claims; AAA Case No. 01-24-0000-0775. The Superior Court Action has been stayed, pending the conclusion of the arbitration. In the meantime, the AAA has empaneled three experienced arbitrators and has set the hearing date for the matter, currently schedule in May 2026.

The EPC Agreement requires that CEI, continue working during the course of the litigation and related arbitration proceedings; however, CEI effectively stopped working. Between May and August 2024, MD issued a series of Notices of Default and Demands to Cure to CEI. CEI failed to cure, and on July 30, 2024, MD terminated CEI for default. MD notified CEI’s performance bond surety, Atlantic Specialty Insurance Company of the termination and demanded that it perform under the bond. Atlantic has denied the claim.

33

On July 11, 2024, VS issued a Notice of Default and Demand to Cure, advising CEI of its defaults and giving it an opportunity to cure. CEI failed to do so, and on August 27, 2024, VS terminated CEI for default. VS has notified CEI’s bond surety, also Atlantic, of the second termination and demanded that it perform under the performance bond. The surety has denied the claim.

As a result of CEI’s default and Atlantic’s denial of the claims, MD and VS have amended their claims in the AAA arbitration to include breach of contract claims against CEI and breach of performance bond and payment bond claims against Atlantic (who was formally joined into the arbitration on November 20, 2024) in the AAA Arbitration with CEI.

CEI has since recorded mechanic’s liens against each of the projects for $4,900 (MD) and $2,000 (VS), and filed actions with the Stanislaus and San Joaquin County Superior Courts, respectively, to enforce their liens. MD and VS have since recorded bonds releasing the properties from the liens and it is expected that these claims will be stayed and consolidated with the pending arbitration proceeding.

In addition to the above-referenced action and arbitration, several of CEI’s subcontractors have recorded mechanic’s liens against the MD and VS projects for $3,141, which the Company is obligated to defend and indemnify the dairy owners from and against. Several liens were untimely and have been released.

The Company believes its claims against CEI (and the surety where bond claims are denied) have substantial merit, and intends to prosecute the claims vigorously. However, due to the incipient stage of the litigation and related arbitration, the recency of the termination, and the ongoing status of the proceedings and discussions with the bond surety, as well as the uncertainties involved in all litigation and arbitration, the Company is unable at this time to assess the likely outcome of the litigation and related arbitration, the timing of its resolution, or its ultimate impact, if any, on the Central Valley projects or the Company's business, financial condition or results of operations.

Former Development Partner/Construction Manager

In March 2024, the Company filed an action in the Orange County Superior Court (Case No. 30- 2024-01415510-CU-BC-CXC) against its former development partner and construction manager, Sierra Renewable Organics Management, LLC, as well as its principal (Ethan Werner) and affiliated engineering firm (CH Four Biogas) for Breach of Contract, Indemnity, Declaratory Relief, Intentional Misrepresentation and Negligent Misrepresentation relating to the design and development of the Projects. The defendants have recently filed an answer and certain cross claims, to which the Company has demurred. Discovery in the case is now underway.

13. Subsequent Events

On October 6, 2025, the Company's Atlantic RNG facility commenced commercial operations. This project represents approximately 0.3 million MMBtu for Opal's 50% ownership share of annual design capacity.

In October 2025, the Company began construction of the CMS Concord RNG facility in North Carolina. This project represents approximately 0.7 million MMBtu for Opal's 70% ownership share of annual design capacity.

There have been no other subsequent events, that occurred during such period that would require disclosure in this Form 10-Q or would be required to be recognized in the consolidated financial statements as of and for the three and nine months ended September 30, 2025.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

In this Management's Discussion and Analysis of Financial Condition and Results of Operations section, references to "OPAL," "we," "us," "our," and the "Company" refer to OPAL Fuels Inc. and its consolidated subsidiaries. The following discussion and analysis should be read in conjunction with our unaudited condensed consolidated financial statements as of September 30, 2025 and for the three and nine months ended September 30, 2025 and 2024, and the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the SEC on March 17, 2025. In addition to historical information, this discussion and analysis includes certain forward-looking statements which reflect our current expectations. The Company's actual results may materially differ from these forward-looking statements.

Overview

The Company is a vertically integrated leader in the capture and conversion of biogas into low carbon intensity Renewable Power and RNG. OPAL Fuels is also a leader in the marketing and distribution of RNG to heavy duty trucking and other hard to de-carbonize industrial sectors. RNG is chemically identical to the natural gas used for cooking, heating homes and fueling natural gas engines, with one significant difference: RNG is produced by recycling methane emissions created by decaying organic waste as opposed to natural gas which is a fossil fuel pumped from the ground. We have participated in the biogas-to-energy industry for over 20 years.

Biogas is generated by microbes as they break down organic matter in the absence of oxygen, and is comprised of non-fossil waste gas, with high concentrations of methane, which is the primary component of RNG and the source for combustion utilized by Renewable Power plants to generate electricity. Biogas can not only be collected and processed to remove impurities for use as RNG (a form of high-Btu fuel) and injected into existing natural gas pipelines as it is fully interchangeable with fossil natural gas, but partially treated biogas can be used directly in heating applications (as a form of medium-Btu fuel) or in the production of Renewable Power. Our principal sources of biogas are (i) landfill gas, which is produced by the decomposition of organic waste at landfills, and (ii) dairy manure, which is processed through anaerobic digesters to produce the biogas.

We also design, develop, construct, operate and service Fueling Stations for trucking fleets across the country that use natural gas to displace diesel as their transportation fuel. We have participated in the alternative vehicle fuels industry for over a decade and have established an expanding network of Fueling Stations for dispensing RNG. In addition, we have recently begun implementing design, development, and construction services for hydrogen fueling stations, and we are pursuing opportunities to diversify our sources of biogas to other waste streams.

As of September 30, 2025, we owned and operated 26 projects, 11 of which are RNG projects and 15 of which are Renewable Power Projects. As of that date, our RNG projects in operation had a design capacity of 8.8 million MMBtus per year and our Renewable Power Projects in operation had a nameplate capacity of 105.8 MW per hour. In addition to these projects in operation, we are actively pursuing expansion of our RNG-generating capacity and, accordingly, have a portfolio of RNG projects in construction or in development, with six of our current Renewable Power Projects being considered candidates for conversion to RNG projects in the foreseeable future.

Recent Developments

On October 6, 2025, the Company's Atlantic RNG facility commenced commercial operations. This project represents approximately 0.3 million MMBtu for Opal's 50% ownership share of annual design capacity.

In October 2025, the Company began construction of the CMS Concord RNG facility in North Carolina. This project represents approximately 0.7 million MMBtu for Opal's 70% ownership share of annual design capacity.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our interim unaudited condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") and the rules and regulations of the SEC, which apply to interim financial statements. The preparation of those financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues, costs and expenses and related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions and conditions.

35

Critical accounting policies are those that reflect significant judgments of uncertainties and potentially result in materially different results under different assumptions and conditions. For a detailed description of all our accounting policies, see Note 1. Summary of Significant Accounting Policies, to our condensed consolidated financial statements included herein and the section titled “Critical Accounting Policies and Estimates” contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes to our critical accounting policies since our Annual Report on Form 10-K for the year ended December 31, 2024.

Key Factors and Trends Influencing our Results of Operations

The principal factors affecting our results of operations and financial condition are the markets for RNG, Renewable Power, and associated Environmental Attributes, access to suitable biogas production resources, the regulatory environment of our industry, and the seasonality of demand and pricing for our products. Additional factors and trends affecting our business are discussed in "Risk Factors" elsewhere in this report.

Market Demand for RNG

Demand for our converted biogas and associated Environmental Attributes, including RINs and LCFS credits, is heavily influenced by United States federal and state energy regulations together with commercial interest in renewable energy products. Markets for RINs and LCFS credits arise from regulatory mandates that require refiners and blenders to incorporate renewable content into transportation fuels. The EPA sets proposed RVOs for D3 RINs in accordance with the mandates established by the Energy Independence and Security Act of 2007. In June 2023, the EPA set RVOs for 2023 through 2025 via a new Set rule. This 3 year RVO is expiring at the end of this year. In June 2025, the EPA announced a proposed "Set 2 Rule" to establish RVOs for 2026 and 2027, with rule finalization expected in late 2025 or early 2026. Until the rules and RVOs are finalized, there may be uncertainty as to RIN pricing for the associated period. On the state level, the economics of RNG are enhanced by low-carbon fuel initiatives, particularly well-established programs in California, Washington and Oregon (with several other states also actively considering LCFS initiatives similar to those in California, Washington and Oregon). Federal and state regulatory developments could result in significant future changes to market demand for the RINs and LCFS credits we produce. This would have a corresponding impact to our revenue, net income, and cash flow.

Transportation, including heavy-duty trucking, generates approximately 30% of overall carbon dioxide and other climate-harming GHG emissions in the United States, and transitioning this sector to low and negative carbon fuels is a critical step towards reducing overall global GHG emissions. The adoption rate of RNG-powered vehicles by commercial transportation fleets will significantly impact demand for our products.

We are also exposed to the commodity prices of natural gas and diesel, which serve as alternative fuel for RNG and therefore impact the demand for RNG.

Renewable Power Markets

We also generate revenues from sales of Renewable Power generated by our biogas-to-Renewable Power projects, and associated RECs. RECs exist because of legal and governmental regulatory requirements in Europe and the United States, respectively, and a change in law or in governmental policies concerning Renewable Power, LFG, or RECs could affect the market for, and the pricing of, such power and credits.

We periodically evaluate opportunities to convert existing Renewable Power projects to RNG production. We have been negotiating with several of our landfill and Renewable Power counterparties to enter into arrangements that would enable the LFG resource to produce RNG. Changes in the price we receive for Renewable Power and associated RECs, together with the revenue opportunities and conversion costs associated with converting our LFG sites to RNG production, could have a significant impact on our future profitability.

Regulatory landscape

We operate in an industry that is subject to and currently benefits from environmental regulations. Government policies can increase demand for our products by providing incentives to purchase RNG and Environmental Attributes. These government policies are modified and in flux constantly and any adverse changes to these policies could have a material effect on the demand for our products. For more information, see the risk factors in our Annual Report on Form 10-K for the year ended December 31, 2024, including the risk factor titled "The financial performance of our business depends upon tax and other government incentives for the generation of RNG and Renewable Power, any of which could

36

change at any time and such changes may negatively impact our growth strategy." Government regulations have become increasingly stringent and complying with changes in regulations may result in significant additional operating expenses.

Seasonality

We experience seasonality in our results of operations. Sale of RNG may be impacted by higher consumption by some of our customers during summer months. Additionally, the price of RNG is higher during the fall and winter months due to increase in overall demand for natural gas during the winter months. Revenues generated from our renewable electricity projects in the northeast U.S., all of which sell electricity at market prices, are affected by warmer and colder weather, and therefore a portion of our quarterly operating results and cash flows are affected by pricing changes due to regional temperatures. These seasonal variances are managed in part by certain off-take agreements at fixed prices.

Key Components of Our Results of Operations

We generate revenues from the sale of RNG fuel, Renewable Power, and associated Environmental Attributes, as well as from the construction, fuel supply, and servicing of Fueling Stations for commercial transportation vehicles using natural gas to power their fleets. These revenue sources are presented in our condensed consolidated statements of operations under the following captions:

•RNG Fuel. The RNG Fuel segment includes RNG supply as well as the associated generation and sale of commodity natural gas and environmental credits, and consists of:

◦RNG Production Facilities – the design, development, construction, maintenance and operation of facilities that convert raw biogas into pipeline quality natural gas; and

◦Our interests in both operating and construction projects.

•Fuel Station Services. Through our Fuel Station Services segment, we provide construction and maintenance services to third-party owners of vehicle Fueling Stations and perform fuel dispensing activities including generation and minting of environmental credits. This segment includes:

◦Manufacturing division that builds Compact Fueling Systems and Defueling systems;

◦Design/Build contracts where we serve as general contractor for construction of Fueling Stations, typically structured as Guarantee Maximum Price or fixed priced contracts for customers, generally lasting less than one year;

◦Service and maintenance contracts for RNG/CNG Fueling Stations; and

◦RNG and CNG Fuel Dispensing Stations - This includes both the dispensing (or sale) of RNG, CNG, and environmental credit generation and monetization. We operate Fueling Stations that dispense both CNG and RNG fuel for vehicles.

•Renewable Power. The Renewable Power segment generates renewable power and associated Environmental Attributes such as RECs through combustion of biogas from landfills which is then sold to public utilities throughout the United States.

Our costs of sales associated with each revenue category are as follows:

•RNG Fuel. Includes royalty payments to biogas site owners for the biogas we use; service provider costs; salaries and other indirect expenses related to the production process; utilities, transportation, storage, and insurance; and depreciation of production facilities.

•Fuel Station Services. Includes equipment supplier costs; service provider costs; and salaries and other indirect expenses.

•Renewable Power. Includes royalty payments; land usage costs; service provider costs; salaries and other indirect expenses related to the production process; utilities; and depreciation of production facilities.

Project development and start up costs includes certain development costs such as legal fees, consulting fees for joint venture structuring, royalties to the landfill owner, fines, settlements, site lease expenses and certification costs on

37

our RNG projects under construction. Additionally, the Company also incurs certain expenses on new RNG projects during the first two years that such projects are operational, such as virtual pipeline costs (incurred until a physical interconnect pipeline is built) and ramp up costs incurred during the certification period.

Selling, general, and administrative expense consists of costs involving corporate overhead functions, including the cost of services provided to us by an affiliate, and marketing costs.

Depreciation and amortization primarily relate to depreciation associated with property, plant, and equipment and amortization of acquired intangibles arising from PPAs and interconnection contracts. We are in the process of expanding our RNG and Renewable Power production capacity and expect depreciation costs to increase as new projects are placed into service.

Operational data

The following table summarizes the operational data achieved for the three and nine months ended September 30, 2025 and 2024:

Landfill RNG Facility Capacity and Utilization Summary

			Three Months Ended September 30,						Nine Months Ended September 30,
			2025			2024			2025			2024
Landfill RNG Facility Capacity and Utilization
Design Capacity (Million MMBtus) (1)			2.2			1.7			6.4			4.5
Volume of Inlet Gas (Million MMBtus) (2)			1.6			1.2			4.6			3.3
Inlet Design Capacity Utilization (%) (2)			80		%	72		%	73		%	75		%
RNG Fuel volume produced (Million MMBtus)(3)			1.2			1.0			3.4			2.6
Utilization of Inlet Gas (%) (4)			77		%	84		%	76		%	82		%

38

(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.

			Three Months Ended September 30,						Nine Months Ended September 30,

Renewable Power produced (Millions MWh)			0.09			0.09			0.26			0.27
Nameplate Capacity Utilization (%) (2)			39		%	41		%	38		%	39		%

(1) Nameplate Capacity for Renewable Power facilities is the manufacturer’s expected capacity at ISO conditions for each facility and may not reflect actual production from the projects, which depends on many variables including, but not limited to, (i) quantity and quality of the biogas, (ii) operational up-time of the facility, including dispatch and maintenance downtime and (iii) actual efficiency of the facility.

(2) Nameplate Capacity Utilization for Renewable Power facilities is measured as Renewable Power Produced divided by Design Capacity for the period. Given (i) built-in un-utilized capacity from historical designs, (ii) availability (a function of higher maintenance requirements compared to RNG facilities) and (iii) commencement of operations of the Emerald RNG facility, which will result in low levels of dispatch for the Arbor Hills facility (which will operate on a standby basis but remain in the operating portfolio), the Company’s Design Capacity Utilization is expected to remain below 50%.

(1) Reflects the Company’s ownership share of design capacity for projects that are not 100% owned by the Company (i.e., net of joint venture partners’ ownership). Design capacity is measured as the volume of feedstock biogas that the plant is capable of accepting at the inlet and processing and may not reflect actual production of RNG from the projects, which will depend on many variables including, but not limited to, (i) quantity and quality of the biogas, (ii) operational up-time of the facility and (iii) actual efficiency of the facility.

(2) We record our ownership interests in these projects as equity method investments in our condensed consolidated financial statements.

(3) This project has provisions that will adjust or “flip” the percentage of distributions to be made to us over time, typically triggered by achievement of hurdle rates that are calculated as internal rates of return on capital invested in the project.

(4) Expected Commercial Operation Date (“COD”) for commencement of the RNG projects in construction is based on the Company’s estimate as of the date of this report. CODs are estimates and are subject to change as a result of, among other factors out of the Company’s control: (i) regulatory/permitting approval timing, (ii) disruption in supply chains and (iii) construction timing.

(5) Please see Part II, Item 1: Legal Proceedings and Note 12 - Commitments and Contingencies to the condensed consolidated financial statements.

(6) The construction of the Cottonwood, Burlington, and Kirby Canyon projects began in the second, third, and fourth quarters of 2024, respectively.

(7) COD date is October 2025.

(1) Nameplate capacity is the manufacturer’s expected capacity at ISO conditions for each facility and may not reflect actual production from the projects, which depends on many variables including, but not limited to, (i) quantity and quality of the biogas, (ii) operational up-time of the facility and (iii) actual productivity of the facility.

(2) We have determined that some of our Renewable Power projects are currently RNG conversion candidates. The Company identifies suitable RNG conversion candidates based on highest return of capital which is driven by certain factors including, but not limited to (i) the quantity and quality of LFG, (ii) the proximity to pipeline interconnect and (iii) the ability to enter into contracts, including site leases and gas rights agreements, with host sites. The Company may change its decision to convert a Renewable Power Project into an RNG project in the future. The Company believes disclosing Renewable Power conversion candidates provides visibility into the effect of those conversions on the existing Renewable Power portfolio.

(3) Although the RNG conversion is completed, it is currently contemplated that the Arbor Hills Renewable Power plant will continue limited operations on a stand-by, emergency basis through March of 2031.

(4) Construction of the Fall River project has been delayed due to permitting issues.

Liquidity and Capital Resources

Liquidity

As of September 30, 2025, our liquidity was $183.8 million, consisting of $138.4 million of unused capacity under our $450.0 million senior secured credit facility, $15.5 million of unused capacity under the associated revolver, and $29.9 million of cash and cash equivalents.

We expect that our available cash together with our other assets, expected cash flows from operations, and access to expected sources of capital will be sufficient to meet our existing commitments for a period of at least twelve months from the date of this report. Any reduction in demand for our products or our ability to manage our production facilities may result in lower cash flows from operations which may impact our ability to make investments and may require changes to our growth plan.

46

To fund future growth, we anticipate seeking additional capital through equity or debt financings. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our project development efforts. We may be unable to obtain any such additional financing on acceptable terms or at all. Our ability to access capital when needed is not assured and, if capital is not available when, and in the amounts needed, we could be required to delay, scale back or abandon some or all of our development programs and other operations, which could materially harm our business, prospects, financial condition, and operating results.

As part of our operations, we have arrangements for office space for our corporate headquarters under the Administrative Services Agreement as well as operating leases for office space, warehouse space, and our vehicle fleet.

We intend to make payments under our various debt instruments when due and pursue opportunities for earlier repayment and/or refinancing if and when these opportunities arise.

See Note 3. Borrowings, to our condensed consolidated financial statements.

OPAL Term Loan

On March 3, 2025, OPAL Fuels Intermediate HoldCo LLC, as the borrower (the “Borrower”), certain subsidiaries of the Borrower, as guarantors (the “Guarantors”), the lenders and issuers of letters of credit party thereto and Bank of America, N.A. as the administrative agent (the “Administrative Agent”) entered into that certain Amendment No. 1 to Credit and Guarantee Agreement (the “Credit Agreement Amendment”), with respect to that certain Credit and Guarantee Agreement (the “Credit Agreement”) dated September 1, 2023, by and among the Borrower, the Administrative Agent, the financial institutions from time to time parties thereto as lenders and as issuers of letters of credit, and the other agents and persons from time to time party thereto (as amended, restated, amended and restated, supplemented or otherwise modified and in effect from time to time).

The Credit Agreement Amendment makes certain changes to the applicability of certain financial covenants and modifies other covenants to clarify the use of loan proceeds. Additionally, the Credit Agreement Amendment permits the organizational restructuring of the Guarantors in a manner designed to facilitate the sale of federal investment tax credits and the ability to raise additional future capital.

The Credit Agreement Amendment also eases the conditions precedent to making new Projects eligible for borrowing under the Credit Agreement, extends the availability period for delay draw term loans under the Credit Agreement through March 5, 2026, and extends the commencement of repayment of such term loans until March 31, 2026.

In connection with the Credit Agreement Amendment, the Borrower paid the Administrative Agent, for the account of each lender, a one-time nonrefundable fee of $1.25 million.

As of September 30, 2025 and December 31, 2024, the outstanding loan balance (current and non-current) excluding deferred financing costs was $331.6 million and $286.6 million, respectively.

The Company has the ability, during the delayed draw availability period and subject to the satisfaction of certain credit and project-related conditions precedent, to join other newly acquired subsidiaries with comparable renewable projects in development under the credit facility for comparable funding. As of September 30, 2025, the Company is in compliance with the financial covenants under the OPAL Term Loan.

On July 19, 2022, Sunoma completed the conversion of the construction loan into a permanent loan and increased the commitment from $20.0 to $23.0 million. The maturity date is July 19, 2033. The outstanding loans under the Sunoma Loan Agreement bear interest at an annual fixed rates of 7.8%, and 8.2% per annum during the term.

The Sunoma Loan Agreement contains certain financial covenants which require Sunoma to maintain (i) a maximum debt to net worth ratio not to exceed 5:1, (ii) a minimum current ratio not less than 1.0 and (iii) a minimum debt service coverage ratio of trailing four quarters not less than 1.25. As of September 30, 2025, Sunoma is in compliance with the financial covenants under the Sunoma Loan Agreement.

47

As of September 30, 2025 and December 31, 2024, the outstanding loan balance (current and non-current) excluding deferred financing costs was $19.5 million and $20.8 million, respectively.

Redeemable Series A Preferred Units of OPAL Fuels LLC

In November 2021, NextEra subscribed for an aggregate of $100,000,000 of Series A preferred units issued by OPAL Fuels LLC, a consolidated subsidiary of OPAL Fuels, Inc. The Series A preferred units have limited rights to prevent OPAL Fuels LLC from taking certain actions including (i) major issuances of new debt or equity (ii) executing transactions with affiliates which are not at arm-length basis (iii) major disposition of assets and (iv) major acquisition of assets outside of OPAL Fuels LLC’s primary business. The Series A preferred units are entitled to receive dividends at the rate of 8% per annum. Dividends begin accruing for each unit from the date of issuance and are payable each quarter end regardless of whether they are declared. The dividends are mandatory and cumulative. The Company was allowed to elect to issue additional Series A preferred units (paid-in-kind) in lieu of cash for the first eight dividend payment dates. As of September 30, 2025 and December 31, 2024, there was no accrued preferred dividend payable.

At any time after issuance, OPAL Fuels LLC may redeem the Series A preferred units for a price equal to original issue price of $100 per unit plus any accrued and unpaid dividends. Upon written notice from NextEra at any time after November 29, 2025, we would be required to redeem the Series A preferred units. In the event the Company does not redeem the Series A preferred units when requested, NextEra will have the following rights and remedies: (1) NextEra’s affiliate may extend the RNG Marketing Agreement by 12 months; or (2) the dividend rate would increase depending on the length of time the Series A preferred units remain unredeemed to up to 20% per annum, and if more than $25,000,000 preferred equity is outstanding for more than six months after November 29, 2025, NextEra may appoint a director to OPAL Fuel Inc.’s Board of Directors; or (3) NextEra may convert the Series A preferred equity into common equity of the OPAL Fuels LLC at a conversion price at a 20% to 30% discount to their value (the discount is 20% during the first 12 months after November 29, 2025, 25% for the next 12 months thereafter and 30% thereafter).

Cash Flows

The following table presents the Company's cash flows for the nine months ended September 30, 2025 and 2024:

			Nine Months Ended September 30,
(in thousands)			2025			2024
Net cash provided by operating activities			$	40,017		$	31,917
Net cash used in investing activities			(69,933)			(86,546)
Net cash provided by financing activities			34,971			31,581
Net increase (decrease) in cash, restricted cash, and cash equivalents			$	5,055		$	(23,048)

Net Cash Provided by Operating Activities

Net cash provided by operating activities for the nine months ended September 30, 2025 was $40.0 million, an increase of $8.1 million compared to $31.9 million for the nine months ended September 30, 2024.

The increase was primarily attributable to higher net income driven by increased revenues, lower income from equity method investments, and higher non-cash items. These were partially offset by unfavorable changes in working capital and a decrease in distributions from equity method investments.

Net Cash Used in Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2025 was $69.9 million, a decrease of $16.6 million compared to the $86.5 million used in investing activities for the nine months ended September 30, 2024.

This was primarily driven by a decrease in payments made for the construction of various RNG generation and dispensing facilities in 2025 compared to 2024, an increase in distributions received from equity method investments, and a decrease in payments made for the purchase of short-term investments and an increase cash from notes receivable, partially offset by higher contributions made to equity method investments.

48

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2025 was $35.0 million, an increase of $3.4 million compared to the net cash used in financing activities of $31.6 million for the nine months ended September 30, 2024.

This was primarily driven by an increase in proceeds from long-term loans, a decrease in dividend payments on redeemable preferred non-controlling interests, and an increase related to the acquisition of a controlling interest. These were partially offset by long-term loan repayments and higher financing costs paid to third parties.

Capital expenditures and other cash commitments

We require cash to fund our capital expenditures, operating expenses and working capital and other requirements, including costs associated with fuel sales; outlays for the design and construction of new Fueling Stations and RNG production facilities; debt repayments and repurchases; maintenance of our electrification production facilities supporting our operations, including maintenance and improvements of our infrastructure; supporting our sales and marketing activities, including support of legislative and regulatory initiatives; any investments in other entities; any mergers or acquisitions, including acquisitions to expand our RNG production capacity; pursuing market expansion as opportunities arise, including geographically and to new customer markets; and to fund other activities or pursuits and for other general corporate purposes.

As of September 30, 2025, we anticipate spending of approximately $144.3 million in capital expenditures for the next 12 months for RNG projects, fuel stations and our share of contributions in our equity method investment projects. This includes projects which have not been fully committed. These expenditures do not include any expected contributions from our joint venture partners and primarily relate to our development and construction of new renewable energy facilities and the purchase of equipment used in our Fueling Station services and Renewable Power operations.

In addition to the above, we also have lease commitments on our vehicle fleets and office leases and quarterly amortization payment obligations under various debt facilities. Please see Note 3. Borrowings and Note 12. Commitments and Contingencies to our condensed consolidated financial statements for additional information.

We plan to fund these expenditures primarily through cash on hand, cash generated from operations and availability under existing debt facilities.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Co-Chief Executive Officers and our Chief Financial Officer (our co-principal executive officers and principal financial officer, respectively), evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act. The term “disclosure controls and procedures,” as defined in the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on that evaluation of our disclosure controls and procedures as required by Rules 13a-15(b) or 15d-15(b) under the Exchange Act, as of September 30, 2025, our Co-Chief Executive Officers and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective for the period covered by this report.
