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. In the opinion of management, the Company's financial statements include all normal and recurring adjustments necessary in order to make the financial statements not misleading and to provide a fair presentation of the Company's financial results for the interim period included in this Quarterly Report. The information included in this Quarterly Report should be read in conjunction with the Company's 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.

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' equity (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' equity (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.

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.

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 adoption of ASU 2025-10 in the third quarter of 2026 and retrospective application of its provisions. The Company is currently evaluating the impact of adoption on its financial statements, including the presentation of Section 45z production tax credits.

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 $5,140 and $6,489 as of June 30, 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 six months ended June 30, 2026, the Company recognized revenue of $3,510 that was included in contract liabilities at December 31, 2025. During the six months ended June 30, 2025, the Company recognized revenue of $3,404 that was included in contract liabilities at December 31, 2024.

During the three months ended June 30, 2026, the Company recognized impairment charges of $3,595 related to certain long-lived assets in its Renewable Power segment and $547 related to certain long-lived assets in its Fuel Station Services segment. The impairment within its Renewable Power segment resulted from the Company's decision to repurpose a renewable power facility for use as an RNG facility. As a result of the change in intended use, certain assets associated with the renewable power facility were no longer expected to be utilized and had no alternative future use.

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 June 30, 2026, the Company had a remaining performance obligation of $32,653 of which $12,068 is expected to be recognized within the next 12 months.
