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. Words such as “anticipates,” “believes,” "could," “estimates,” “expects,” “forecasts,” “future,” “goal,” “intends,” “may,” “objective,” “outlook,” “plans,” "potential," “projected,” “propose,” “seeks,” "should," “target,” “will,” “would” and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify 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 Quarterly Report on 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 Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K, which was filed with the SEC on March 16, 2026 (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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The unaudited condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"). The Company’s unaudited condensed consolidated financial statements include the assets and liabilities of these subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

The Company consolidates all entities in which it holds a majority voting interest, as well as variable interest entities ("VIEs") for which it is determined to be the primary beneficiary. The Company's variable interests in each of the VIEs arise primarily from ownership of membership interests, construction commitments, the provision of operating and maintenance services, and the provision of environmental credit processing services to VIEs. The Company reassesses its primary beneficiary status on an ongoing basis.

Noncontrolling interests related to the Company’s VIEs are presented separately from stockholders' deficit on the condensed consolidated balance sheets and are reported as non-redeemable non-controlling interests within the condensed consolidated statements of changes in redeemable non-controlling interest, redeemable preferred non-controlling interest and stockholders' deficit.

Certain amounts in the prior‑period financial statements have been reclassified to conform to the current‑period presentation. These reclassifications had no impact on previously reported total assets, total liabilities, stockholders' deficit, net loss, or condensed consolidated statements of cash flows.

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. Actual results could differ from those estimates.

The significant estimates and assumptions of the Company include the residual value of the useful lives of property, plant and equipment, the fair value of long-lived assets, asset retirement obligations, percentage completion for revenue recognition, incremental borrowing rate for calculating the right-of-use assets and lease liabilities, and the fair value of the reporting units of goodwill.

Accounting Pronouncements Not Yet Adopted

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 expense line items. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The amendments are 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.

In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants Received by Business Entities (Topic 832). This ASU establishes a unified accounting model for business entities when recognizing, measuring, and presenting government grants. The ASU categorizes grants as either related to an asset or related to income. A grant related to income is recognized in earnings in a systematic and rational manner over the periods in which the entity recognizes the related expenses for which the grant is intended to compensate. Presentation of the grant on the income statement can be either as a component of other income or as a deduction from the related expenses. The standard is effective for annual periods beginning after December 15, 2028 and interim periods within those annual periods. However, the ASU permits early adoption. The Company is considering early adopting the provisions of ASU 2025-10 and is still assessing the impact on its financial statements, including the presentation of its Section 45Z production tax credits.

Parts Inventory

Parts inventory, also referred to as supplies inventory, consists of shop spare parts inventory and construction site parts inventory. Parts inventory is stated at historical cost, which is determined using the average cost method, and is recorded at the lower of cost or net realizable value. An annual review of inventory is performed to identify obsolete items.

Environmental Credits Held for Sale

For the three months ended March 31, 2026 and 2025, the Company recorded $2,210 and $5,847 as part of Cost of sales - Fuel Station Services in the condensed consolidated statements of operations to adjust environmental credits held for sale to lower of cost and net realizable value.

Accrued Expenses and Other Current Liabilities

Accrued expenses and other current liabilities consist primarily of accrued capital expenditures, accrued payroll and related benefits, accrued environmental credit rebates, and other miscellaneous accrued operating expenses. Accrued environmental credit rebates represent the Company's liabilities for dispensing services provided by third-party vendors.


	March 31, 2026		December 31, 2025
Accrued capital expenditures	$	24,632	$	24,629
Accrued payroll	6,824		7,719
Accrued environmental credit rebates	5,002		4,993
Accrued expenses	14,735		12,062
Other current liabilities	11,697		14,454
Total accrued expenses and other current liabilities	$	62,890	$	63,857

Contract Balances

Contract assets consist primarily of costs and estimated earnings in excess of billings and retainage receivables. Costs and estimated earnings in excess of billings represent unbilled amounts earned and reimbursable under construction contracts and arise when revenues have been recognized but amounts are conditional and have yet to be billed under the terms of the contract. Amounts become billable in accordance with contract terms, generally based on progress toward completion and the achievement of contractual milestones. Cost and estimated earnings in excess of billings amounted to $4,920 and $6,489 as of March 31, 2026 and December 31, 2025, respectively.

Contract liabilities consist of billings in excess of costs and estimated earnings and other deferred construction revenue. Billings in excess of costs and estimated earnings represent amounts billed to or collected from customers in advance of the satisfaction of the related performance obligations. These amounts are recognized as revenue as the Company satisfies its performance obligations over the remaining contract term.

During the three months ended March 31, 2026, the Company recognized revenue of $1,353 that was included in contract liabilities at December 31, 2025. During the three months ended March 31, 2025, the Company recognized revenue of $2,307 that was included in contract liabilities at December 31, 2024.

Remaining Performance Obligations

The Company's remaining performance obligations represent the unrecognized revenue value of its contract commitments. The Company's remaining performance obligations may significantly vary each reporting period based on the timing of major new contract commitments. As of March 31, 2026, the Company had a remaining performance obligation of $36,902 of which $26,052 is expected to be recognized within the next 12 months.

Significant Customers, Vendors and Concentration of Credit Risk

At March 31, 2026, one customer accounted for 36% of accounts receivable. At December 31, 2025, four customers accounted for 63% of accounts receivable.

During the three months ended March 31, 2026, there were no concentrations in the volume of business transacted with any individual vendor. During the three months ended March 31, 2025, there was one supplier that accounted for approximately 19.3% of the Company’s total purchases.

Refer to Note 7. Reportable Segments and Geographic Information for details on revenue concentration.

2. INVESTMENTS IN OTHER ENTITIES AND VARIABLE INTEREST ENTITIES

The Company’s VIEs consist of landfill or dairy manure RNG facilities that are either under construction or in operation. OPAL’s share of design capacity for these facilities ranges from approximately 43,750 MMBtu to 1,327,140 MMBtu per year. These entities are financed through the Opal Term Loan, the Sunoma Loan, or the Paragon Loan. The Paragon Loan was obtained directly by the joint venture and is not consolidated.

VIEs for which the Company is not the primary beneficiary are accounted for under the equity method. As of March 31, 2026, Sunoma, Central Valley and CMS were consolidated VIEs.

The condensed consolidated balance sheets summarize the major consolidated balance sheet items for consolidated VIEs as of March 31, 2026 and December 31, 2025. The information is presented on an aggregate basis based on similar risk and reward characteristics and the nature of our involvement with the VIEs. All VIEs are RNG facilities reported under the RNG Fuel Supply segment, and the Company’s interests are primarily equity-based.

The following table presents the Company's ownership interests and carrying values of Investment in Other Entities:


	Pine Bend			Noble Road			GREP			Land2Gas			Paragon			Other			Total
Percentage of ownership	50		%	50		%	20		%	50		%	50		%	50		%
Balance at December 31, 2025	$	19,864		$	20,755		$	594		$	36,554		$	153,456		$	—		$	231,223
Balance at March 31, 2026	$	18,604		$	19,710		$	323		$	34,811		$	150,684		$	150		$	224,282

As of March 31, 2026 and December 31, 2025, the carrying value of the Company’s equity method investments exceeded its proportionate share of the underlying net assets of its investees by $120,464 and $122,165, respectively. This basis difference primarily relates to the gain recognized upon the deconsolidation of certain RNG project entities, which increased the Company’s investment basis. The Company determined that this basis difference is attributable to construction in progress and will be amortized over the related assets’ estimated useful life of 20 years beginning when the assets are placed in service. The amortization of this basis difference, which reduces equity in earnings, was $1,700 and $1,700 and reflected in loss from equity method investments in the condensed consolidated statements of operations for the three months ended March 31, 2026 and 2025, respectively.

The following table summarizes the loss from equity method investments:


	Three Months Ended March 31,
		2026		2025
Revenue		$	27,311	$	22,517
Gross profit		3,244		2,815
Net loss (1)		(2,284)		(2,266)

(1) Net loss from equity method investments represents the Company's portion of the net loss from equity method investments including amortization of any basis differences.

A summary of financial information for our portion of the assets and liabilities in equity method investees in the aggregate is as follows:


	March 31, 2026		December 31, 2025
Current assets	$	15,837	$	27,566

During the three months ended March 31, 2026, the Company drew $128,382 under its term loan facility pursuant to its existing credit agreement. A portion of the proceeds from the borrowing was used to repay $20,000 outstanding under the revolving loan facility. As of March 31, 2026, the Company had utilized $10,747 of availability under the revolver loan to provide for the issuance of letters of credit to support the operations of OPAL Fuels Intermediate HoldCo LLC (the “Borrower”) and certain subsidiaries of the Borrower (the “Guarantors”).

During the three months ended March 31, 2026, the Company commenced principal payments under its credit agreement. In addition, beginning in the first quarter of 2026, the Company is subject to a quarterly cash sweep pursuant to which, within two business days after the required delivery of quarterly financial statements, a percentage of distributable cash is required to be applied to repay outstanding borrowings, with the applicable percentage determined based on the Company’s consolidated debt to cash flow ratio. If the required financial statements are not delivered within the specified timeframe, 100% of distributable cash is required to be applied to the cash sweep.

Sunoma Loan

The Company utilized $927 for the issuance of letters of credit to support the operations.

4. LEASES

Lessor contracts

Sales-Type Leases

During the three months ended March 31, 2026, the Company entered into a new sales-type lease.

7. REPORTABLE SEGMENTS AND GEOGRAPHIC INFORMATION

The Company is organized into three operating segments.

During the fourth quarter of 2025, the Company changed the presentation of information reviewed by the Chief Operating Decision Makers (“CODM”) to allocate certain Corporate general and administrative costs, including consulting, insurance, and payroll expenses, to the related reportable segments. Segment information has been retrospectively revised to reflect this change. All the assets and revenue-generating activities, aside from sales‑type lease in Canada, were domiciled in the United States for the three months ended March 31, 2026 and 2025. Transactions between reportable segments are accounted for using market‑based pricing. Intersegment revenues and expenses are eliminated in consolidation.

During the fourth quarter of 2025, the Company changed the presentation of information reviewed by the CODM to allocate certain Corporate general and administrative costs, including consulting, insurance, and payroll expenses, to the related reportable segments. Segment information has been retrospectively revised to reflect this change. For the three months ended March 31, 2025, amounts reallocated from Corporate to RNG Fuel, Fuel Station Services, and Renewable Power were $2,292, $336, and $962, respectively.

The following table reflects the financial data used to calculate each reportable segment’s income (loss) and includes reconciliations to the Company's consolidated revenue and consolidated net income for the three months ended March 31, 2026:

8. REDEEMABLE NON-CONTROLLING INTEREST, REDEEMABLE PREFERRED NON-CONTROLLING INTEREST AND STOCKHOLDERS' EQUITY

Common stock

As of March 31, 2026, the Company is authorized to issue 340,000,000 shares of Class A common stock, 160,000,000 shares of Class B common stock, 160,000,000 shares of Class C common stock, and 160,000,000 shares of Class D common stock.

Shares of Class B and Class D common stock do not have any economic value except voting rights as described below.

Redeemable Preferred Non-controlling Interests

Upon completion of the Business Combination, the Company effectively assumed the Series A‑1 and Series A preferred units previously issued by OPAL Fuels LLC to Hillman and NextEra, respectively. Following the transaction, these preferred units were presented as redeemable preferred non-controlling interests in the Company’s condensed consolidated financial statements.

On March 6, 2026, OPAL Fuels LLC (“Opal Fuels”), the Company’s primary operating consolidated subsidiary, entered into a subscription agreement (“Subscription Agreement”) with Preferred Fuels LLC, (“Preferred Fuels” or “Investor”), an entity under common control with the Company. Pursuant to the Subscription Agreement Preferred Fuels committed to purchase up to $180,000 (the “Offering”) of Series A preferred units of Opal Fuels in multiple closings. At the initial closing on March 6, 2026, Preferred Fuels purchased 1,200,000 preferred units for aggregate proceeds of $120,000. OPAL Fuels may, in its sole discretion, require Preferred Fuels to fund up to an additional $60,000 (or “Undrawn Commitment”) within one year of the initial closing (“or Availability Period”), subject to the terms of the Subscription Agreement. Additionally, pursuant to the Subscription Agreement, the Investor also has a right of first offer to purchase up to an additional 700,000 Units for an aggregate purchase price of up to $70,000 in the Offering in the event that OPAL Fuels intends to sell any additional units prior to the two (2) year anniversary of the initial closing. Opal Fuels used the proceeds received from the issuance of the Series A preferred units on March 6, 2026 to redeem all of the previously issued and outstanding Series A preferred units.

the extent that after giving effect to such exercise, such person would beneficially own in excess of 19.9% of the Company’s outstanding common stock immediately after giving effect to such exercise. Up to 720,000 shares of the Warrant Shares are forfeitable if Preferred Fuels fails to fund issuance of the remaining Series A preferred units during the Availability Period provided Opal Fuels requested such funding. As of March 31, 2026, no drawdown request has been made.

Additionally, up to 840,000 shares issuable on a pro rata basis upon future purchases by Preferred Fuels of up to an additional 700,000 Series A preferred units (up to $70,000) within two years of the initial closing pursuant to its right of first offer. No Subsequent Warrant Shares have been issued as of March 31, 2026.

The Company recorded Series A preferred units as redeemable noncontrolling interest in its condensed consolidated financial statements at the amount of proceeds received, less the fair value of the Warrants of $2,760 and directly attributable issuance costs of $3,330. The Series A preferred units are subsequently remeasured to their redemption value as of each reporting date as if such reporting date were the redemption date. The Company concluded that the Warrants are not indexed to the Company’s equity. The Warrants are accounted for as liabilities in the Company’s condensed consolidated financial statements, within other long-term liabilities with changes in fair value recognized in other (expense) income, net.

The following table summarizes the changes in the redeemable preferred non-controlling interests which represent Series A and Series A-1 preferred units outstanding at OPAL Fuels level from December 31, 2025 to March 31, 2026:


	Series A-1 preferred units			Series A preferred units
	Units	Amount		Units	Amount		Total

Terms of Redeemable Preferred Units

The Series A-1 preferred units held by Hillman RNG Investments LLC (Hillman), Series A preferred units previously held by NextEra affiliated entity and the new Series A preferred units (collectively the “Preferred Units”) held by Preferred Fuels, have substantially the same terms and features (unless specified otherwise) which are listed below:

Voting: The Series A-1 preferred units do not have any voting rights. The Series A preferred units carry no voting rights except as required by Delaware law or as provided under certain protective covenants in the Subscription Agreement.

Dividends: The Series A-1 preferred units are entitled to receive dividends at a rate of 8% per annum. The Series A preferred units are entitled to preferred quarterly distributions at a rate of 12% per annum (“Preferred Coupon”), compounding quarterly. Dividends on each series begin accruing from the issuance date, are mandatory and cumulative. OPAL Fuels may elect to pay up to 2% per annum of the 12% Series A Preferred Coupon in kind through the issuance of additional Series A preferred units.

Liquidation preference: In the event of a liquidation of OPAL Fuels, each holder of Series A and Series A-1 units is entitled to receive, on a pro rata basis, the original issue price of $100 per unit plus any accrued and unpaid dividends, out of assets available for distribution after payment of debt, liabilities, and liquidation expenses.

Redemption and Conversion: OPAL Fuels may redeem each series of Preferred Units at any time at the original issue price of $100 per unit plus accrued and unpaid dividends. Under the Series A preferred units, the Company was required to respond within 90 days from the date of the holder’s redemption notice in accordance with the applicable terms.

Preferred Fuels may require redemption upon (i) a change of control, (ii) an uncured material debt default or breach of protective covenants continuing for 60 days, or (iii) at any time on or after the fifth anniversary of the initial closing (March 6, 2031). In the event OPAL Fuels fails to redeem the Series A preferred units when requested: (1) the Preferred Coupon rate increases by an additional 0.50% per quarter, subject to a maximum of 4.00% per annum above the then-applicable rate, with all accrued distributions compounding quarterly at the Preferred Coupon plus the penalty rate; and (2) any residual cash flow of OPAL Fuels and its subsidiaries after operating expenses and capital expenditures must be applied to redeem the Series A preferred units at the applicable Redemption Price until the failure is cured. The applicable Redemption Price is (i) a price equal to at least 1.15 times the original issue price (inclusive of all fees paid and accrued dividends) on or prior to the first anniversary of the initial closing, (ii) 102% of the original issue price (exclusive of fees) after the first but on or prior to the second anniversary, and (iii) the original issue price plus accrued and unpaid cash dividends thereafter. Preferred Fuels also has the right, but not the obligation, to appoint a single director to the Board of Directors of OPAL Fuels Inc. if the redemption failure is not cured within 90 days.

9. NET LOSS PER SHARE

The following table summarizes the calculation of basic and diluted net loss per share:


	Three Months Ended March 31,
	2026		2025
Net loss attributable to Class A common stockholders basic and diluted	$	(2,642)	$	(235)

Weighted average number of shares of Class A common stock - basic	28,298,861		27,718,912

Weighted average number of shares of Class A common stock - diluted	28,298,861		27,718,912
Net loss per share of Class A common stock
Basic	$	(0.09)	$	(0.01)
Diluted	$	(0.09)	$	(0.01)

The basic loss per share for the three months ended March 31, 2026 and 2025 does not include 1,635,783 shares in treasury and 716,650 shares that are issued and outstanding but are contingent on achieving earnout targets.

Additionally, the diluted loss per share of Class A common stock for the three months ended March 31, 2026 and 2025 does not include redeemable preferred non-controlling interests because the substantive contingency for conversion has not been met as of March 31, 2026. It also excludes redeemable non-controlling interests for the three months ended March 31, 2026 and 2025.

For the periods in which loss per share is presented, the following securities were excluded from the computation of diluted loss per share since their impact would have been antidilutive:


	Three Months Ended March 31,
		2026	2025

Guaranty

On March 30, 2026, Land2Gas LLC, a 50%-owned equity method investee, sold $22,926 of investment tax credits to Athene Annuity and Life Company and Athene Annuity Re II Ltd. for net proceeds of $21,550, of which the Company's 50% share was $10,775. Land2Gas LLC is obligated to return the purchase price and reimburse any taxes, interest, and penalties if the credits are disallowed or recaptured.

The Company and an unaffiliated third party (together, the "Guarantors") each guarantee 50% of these obligations and have entered into a cross-indemnification agreement allocating losses attributable to each party's respective causation. The guarantees include credit support provisions whereby, upon specified credit-related events — including either Guarantor's net worth falling below defined thresholds — the applicable Guarantor may be required to provide letters of credit or cash collateral to the buyers.

The Company's maximum potential exposure represents its 50% proportionate share of the purchase price repayment and related tax indemnification obligations. The Company evaluated these arrangements under ASC 460 and ASC 450 and determined that no material liability was required to be recognized as of March 31, 2026.

Legal Matters

Direct Contractor Claims

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") 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 has submitted a series of change order requests seeking to increase the EPC Contract Price by approximately $14,000, 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; American Arbitration Association ("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 scheduled in May 2027.

The EPC Agreement requires that CEI, continue working during the course of the litigation and related arbitration proceedings; however, CEI effectively stopped working. On June 26, 2024, MD issued a Notice of Default and Demand to Cure to CEI. CEI failed to do so, 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.

Similarly, 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 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 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 4,948 (MD) and 1,984 (VS), and recently filed actions with the Stanislaus and San Joaquin County Superior Courts, respectively, to enforce their liens. It is expected that these claims will be stayed and consolidated with the pending arbitration proceeding.

The AAA proceeding is scheduled for evidentiary hearing from May 3 through June 7, 2027. Based upon the deposition testimony and the expert reports that were exchanged on February 23, 2026, the Company reasonably believes that it will demonstrate that the terminations were justified and for cause. Issues related to damages, i.e., the cost to complete the projects, are evolving and it is premature to offer an opinion on the strength of this component of the case.

Subcontractor Lien Claims

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 of liens were untimely and have been released voluntarily by the claimants, others were released through the recording of release bonds by Company.

The NWP Industries, L.P. ("NWP") and Argo Sales ("Argo") claims have been settled and will be dismissed as to MD and VS when the settlement payments have been fully funded.

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. Discovery in the case is now underway.

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 March 31, 2026 and for the three months ended March 31, 2026 and 2025, 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, 2025, as filed with the SEC on March 16, 2026. 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

Opal Fuels Inc. (the "Company", "Opal", "we", "our" and "us") is a vertically integrated leader in the capture and conversion of biogas into low carbon intensity Renewable Power and RNG. We are 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 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) LFG, 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.

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.

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, 2025. 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, 2025.

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" within our Annual Report on Form 10-K for the year ended December 31, 2025.

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 annually sets proposed renewable volume obligations ("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 three year RVO is expected to reduce volatility in 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, 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 our 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 change at any time and such changes may negatively impact our growth strategy." within our Annual Report on Form 10-K for the year ended December 31, 2025. 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 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 the 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 the Company serves 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 Portfolio. The Renewable Power segment generates Renewable Power and associated Environmental Attributes through combustion of biogas from landfills which is then sold to public utilities throughout the United States. Please see Note 7. Reportable Segments and Geographic Information to our condensed consolidated financial statements for additional information.

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 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 startup 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 our RNG projects under construction. Additionally, we also incur 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 months ended March 31, 2026 and 2025:

Landfill RNG Facility Capacity and Utilization Summary


	Three Months Ended March 31,
		2026		2025
Design Capacity (Million MMBtus) (1)		2.2		2.1
Volume of Inlet Gas (Million MMBtus) (2)		1.5		1.4
Inlet Design Capacity Utilization % (2)		72	%	69	%
RNG Fuel volume produced (Million MMBtus) (3)		1.1		1.1
Utilization of Inlet Gas % (4)		76	%	77	%

(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 our 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 LFG collection system used to recover the LFG. The Design Capacity for each facility will typically be correlated to the amount of LFG expected to be generated by the landfill during the term of the related gas rights agreement. We expect 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 LFG (i.e., concentrations of methane, oxygen, nitrogen, and other gases). We generally expect Utilization of Inlet Gas to be in the range of 80% to 90%. Excludes Sunoma and Biotown.

Renewable Power Capacity and Utilization Summary


	Three Months Ended March 31,
		2026		2025
Nameplate Capacity (MW per hour)(1)		105.8		105.8
Nameplate Capacity for the period (Millions MWh) (1)		0.23		0.23
Renewable Power produced ( Millions MWh)		0.09		0.08
Design Capacity Utilization (%) (2)		39	%	37	%

(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), our Design Capacity Utilization is expected to remain below 50%.

RNG Fuel

Revenue from RNG Fuel decreased by $6.0 million or 22% for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This decrease was primarily a decrease in the sale of environmental attributes. The decrease in environmental attributes was primarily related to a $4.8 million decrease in RIN volume, and a $2.9 million decrease due to RIN price reduction. Partially offset by $1.4 million increase in brown gas sale due to increase in prices.

Fuel Station Services

Revenue from Fuel Station Services decreased by $6.1 million or 12%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to a decrease of $1.6 million in RIN and LCFS minting services, $0.5 million due to lower RIN price partially offset by higher LCFS price, decrease of $5.2 million attributed to lower dispensing and $3.1 million driven by construction projects delays. Offset by sales type leases increase of $3.5 million is due to increase in lease revenues of $2.2 million due to the commencement of a sales-type

outside the United States as well as increase in operating leases $1.3 million in United States and $1.0 million due to increase in GGEs in OPAL owned stations.

Renewable Power

Revenue from Renewable Power was flat for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 as increase in revenues from higher generation was offset by lower environmental attributes.

Cost of sales

RNG Fuel

Cost of sales from RNG Fuel increased by $0.7 million, or 6%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This increase is primarily related to a $1.3 million increase in gas expense, $1.0 million increase in maintenance and $0.3 million higher utilities. This was partially offset by $2.0 million in royalties due to lower environmental credit revenues.

Fuel Station Services

Cost of sales from Fuel Station Services decreased by $4.3 million, or 11%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to a $5.8 million decrease in dispensing fees driven by lower RIN pricing, offset by a $1.5 million increase in FPA tolling expense driven by higher volumes.

Renewable Power

Cost of sales from Renewable Power decreased by $1.1 million, or 17%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to an $0.7 million decrease in major maintenance and a $0.4 million decrease primarily driven by the timing of non-labor and other expenses.

Project development and startup costs

Project development and startup costs decreased by $4.3 million, or 70%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to virtual pipeline costs related to Prince William and Polk facilities.

Selling, general, and administrative

Selling, general, and administrative expenses decreased by a total of $0.8 million, or 5%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to decreases in compensation costs, and advocacy expenses offset by IT and marketing.

Depreciation, amortization, and accretion

Depreciation, amortization, and accretion decreased by a total of $0.3 million, or 6%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to lower depreciation expense in Renewable Power.

Loss from equity method investments

Net loss attributable to equity method investments increased by $1.0 million, or 143%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to a decrease in the realized price of RINs sold on operating facilities and lower production primarily at Pine Bend and Emerald.

Interest and financing expense, net

Interest and financing expenses, net decreased by $0.2 million, or 3%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily related to an increase in interest income from sales-type lease, decrease in interest rates, partially offset by an increase in the average outstanding loan balance.

Other (expense) income

Other income decreased by $1.8 million or 146% for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 primarily related to change in fair value of warrants.

Income tax benefit

Income tax benefit decreased by $2.3 million or 29% for three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily driven by lower generation of transferable tax credits in 2026 compared to 2025.

Net (loss) income attributable to redeemable non-controlling interest

Net (loss) income attributable to redeemable non-controlling interest increased by $11.4 million, or 970%, for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. The net loss for the three months ended March 31, 2026 and 2025 reflects the portion of earnings belonging to OPAL Fuels equity holders. The increase is primarily attributable to higher net loss in the current period compared to the same prior-year period.

Net income attributable to non-redeemable non-controlling interest

Net income attributable to non-redeemable non-controlling interest remained flat for the three months ended March 31, 2026 compared to the three months ended March 31, 2025.

Accretion of the redeemable preferred non-controlling interest to its redemption amount

Accretion of the redeemable preferred non-controlling interest to its redemption amount increased by $6.9 million or 264% for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This is primarily driven by accretion to redemption value following the issuance of redeemable preferred non-controlling interests in March 2026.

Liquidity and Capital Resources

Liquidity

As of March 31, 2026, our liquidity was $232.5 million, consisting of $39.3 million of unused capacity under the revolver, $60.0 million of undrawn preferred stock facility commitments and $133.2 million of cash and cash equivalents. Refer to Note 3. Loans.

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 quarterly 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.

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. In the fourth quarter of 2025, NextEra exercised its redemption option to redeem the preferred units. The Units were redeemed in the first quarter of 2026. Refer to Note 8. Redeemable Non-controlling Interest, Redeemable Preferred Non-controlling Interest and Stockholders' Equity for additional details.

OPAL Term Loan

During the three months ended March 31, 2026, the Company drew $128.4 million under its term loan facility pursuant to its existing credit agreement. A portion of the proceeds from the borrowing was used to repay $20.0 million outstanding under the revolving loan facility. As of March 31, 2026, the Company had utilized $10.7 million 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.

As of March 31, 2026 and December 31, 2025, the outstanding loan balance (current and non-current) excluding deferred financing costs was $437.5 million and $341.6 million, respectively.

We have the ability, during the delayed draw availability period, which expired in March 2026, 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 March 31, 2026, we are in compliance with the financial covenants under the OPAL Term Loan.

Sunoma Loan

On August 27, 2020, Sunoma, an indirect wholly-owned subsidiary of ours entered into a debt agreement (the "Sunoma Loan Agreement") with Live Oak Banking Company for an aggregate principal amount of $20 million. Sunoma paid $0.6 million in financing fees. The amounts outstanding under the Sunoma Loan are secured by the assets of Sunoma. 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 March 31, 2026, Sunoma is in compliance with the financial covenants under the Sunoma Loan Agreement.

As of March 31, 2026 and December 31, 2025, the outstanding loan balance (current and non-current) excluding deferred financing costs was $18.5 million and $19.1 million, respectively.

The significant assets of Sunoma, as well as those of other consolidated variable VIEs, are presented in a separate table below the consolidated balance sheets as of March 31, 2026 and December 31, 2025. See Note 2. Investments in other entities and Variable Interest Entities for additional information.

Redeemable Series A Preferred Units of OPAL Fuels LLC

In November 2021, NextEra subscribed for an aggregate of $100.0 million of Series A preferred units issued by OPAL Fuels LLC, a consolidated subsidiary of OPAL Fuels, Inc.

On March 6, 2026, OPAL Fuels LLC (“Opal Fuels”), the Company’s primary operating consolidated subsidiary, entered into a subscription agreement (“Subscription Agreement”) with Preferred Fuels LLC, (“Preferred Fuels” or “Investor”), an entity under common control with the Company. Pursuant to the Subscription Agreement Preferred Fuels committed to purchase up to $180.0 million (the “Offering”) of Series A preferred units of Opal Fuels in multiple closings. At the initial closing on March 6, 2026, Preferred Fuels purchased 1,200,000 preferred units for aggregate proceeds of $120.0 million. OPAL Fuels may, in its sole discretion, require Preferred Fuels to fund up to an additional $60.0 million (or “Undrawn Commitment”) within one year of the initial closing (“or Availability Period”), subject to the terms of the Subscription Agreement. Additionally, pursuant to the Subscription Agreement, the Investor also has a right of first offer to purchase up to an additional 700,000 Units for an aggregate purchase price of up to $70.0 million in the Offering in the event that OPAL Fuels intends to sell any additional units prior to the two (2) year anniversary of the initial closing. Opal Fuels used the proceeds received from the issuance of the Series A preferred units on March 6, 2026 to redeem all of the previously issued and outstanding Series A preferred units with Nextera.

In connection with the initial closing on March 6, 2026, OPAL Fuels Inc. issued to Preferred Fuels warrants (“Warrants”) to purchase up to 2,160,000 shares of Class A common stock (the “Warrant Shares”) at an exercise price per share of $2.67, subject to customary anti-dilution adjustments. The Warrants expire on March 6, 2034. A holder of the Warrants shall not have the right to exercise the Warrants without prior approval by the Company’s Board of Directors to the extent that after giving effect to such exercise, such person would beneficially own in excess of 19.9% of the Company’s outstanding common stock immediately after giving effect to such exercise. Up to 720,000 shares of the Warrant Shares are forfeitable if Preferred Fuels fails to fund issuance of the remaining Series A preferred units during the Availability Period provided Opal Fuels requested such funding. As of March 31, 2026, no drawdown request has been made.

Additionally, up to 840,000 shares issuable on a pro rata basis upon future purchases by Preferred Fuels of up to an additional 700,000 Series A preferred units (up to $70.0 million) within two years of the initial closing pursuant to its right of first offer. No Subsequent Warrant Shares have been issued as of March 31, 2026.

The Company recorded Series A preferred units as redeemable noncontrolling interest in its condensed consolidated financial statements at the amount of proceeds received, less the fair value of the Warrants of $2.8 million and directly attributable issuance costs of $3.3 million. The Series A preferred units are subsequently remeasured to their redemption value as of each reporting date as if such reporting date were the redemption date, with changes in carrying amount recorded as adjustments to additional paid-in capital to the extent available, with any excess recorded to accumulated deficit. The Company concluded that the Warrants are not indexed to the Company’s equity. The Warrants are accounted for as liabilities in the Company’s condensed consolidated financial statements with changes in fair value recognized in other (expense) income, net.

Terms of Redeemable Preferred Units

Cash Flows

The following table presents our cash flows for the three months ended March 31, 2026 and 2025:


	Three Months Ended March 31,
(in thousands)	2026		2025
Net cash provided by operating activities	$	12,916	$	29,679
Net cash used in investing activities	(19,384)		(9,277)
Net cash provided by (used in) financing activities	115,124		(4,732)
Net increase in cash, restricted cash, and cash equivalents	$	108,656	$	15,670

Net Cash Provided by Operating Activities

Net cash provided by operating activities for the three months ended March 31, 2026 was $12.9 million, a decrease of $16.8 million compared to $29.7 million for the three months ended March 31, 2025.

This was primarily attributable to unfavorable changes in working capital, higher net loss and lower noncash items.

Net Cash Used in Investing Activities

Net cash used in investing activities for the three months ended March 31, 2026 was $19.4 million, an increase of $10.1 million compared to the $9.3 million used in investing activities for the three months ended March 31, 2025.

This was primarily attributable to an increase in payments made for the construction of various RNG generation and dispensing facilities in 2026 compared to 2025 and a decrease in distributions received from equity method investments. These were partially offset by lower contributions made to equity method investments.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2026 was $115.1 million, an increase of $119.9 million compared to the net cash used in financing activities of $4.7 million for the three months ended March 31, 2025.

This was primarily attributable to an increase in proceeds from long-term loans and an increase in from the issuance of preferred stock. These were partially offset by redemption of shares of preferred stock and an increase in repayment of loans.

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 March 31, 2026, we anticipate spending of approximately $155.0 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. Loans 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 3. Quantitative and Qualitative Disclosures About Market Risk

We are not required to provide the information required by this Item because it is a “smaller reporting company.”

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 March 31, 2026, 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.

Changes in Internal Controls over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) under the Exchange Act) was identified in the evaluation required by Rule 13a-15(d) or 15d-15(d) under the Exchange Act during the quarter ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

From time to time, we are involved in various legal proceedings, lawsuits and claims incidental to the conduct of our business, some of which may be material. Our businesses are also subject to extensive regulation, which may result in regulatory proceedings against us. We do not believe that the outcome of any of our current legal proceedings will have a material adverse impact on our business, financial condition and results of operations. For more information about our pending legal proceedings, please refer to Note 12. Commitments and Contingencies.

Item 1A. Risk Factors

Except as described below, there have been no material changes from the “Risk Factors” previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 16, 2026. The risks described in such reports are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information
