Organization, Consolidation and Presentation of Financial Statements [Abstract] |
General | Note 1—General Nature of Business Clean Energy Fuels Corp., together with its majority and wholly owned subsidiaries (hereinafter collectively referred to as the “Company,” unless the context or the use of the term indicates or requires otherwise) is engaged in the business of selling renewable and conventional natural gas as alternative fuels for vehicle fleets and related fueling solutions to its customers, primarily in the United States and Canada. The Company’s principal business is supplying renewable natural gas (“RNG”) and conventional natural gas, in the form of compressed natural gas (“CNG”) and liquefied natural gas (“LNG”), for medium and heavy-duty vehicles and providing operation and maintenance (“O&M”) services to public and private vehicle fleet customer stations. The Company is also focused on developing, owning, and operating dairy and other livestock waste RNG projects and supplying RNG (procured from third party sources and from the Company’s majority owned and jointly owned RNG production facilities (see Note 3)) to its customers in the heavy and medium-duty commercial transportation sector. As a comprehensive clean energy solutions provider, the Company also designs and builds, as well as operates and maintains, public and private vehicle fueling stations in the United States and Canada; sells and services compressors and other equipment used in RNG production and at fueling stations; transports and sells RNG and conventional natural gas, in the form of CNG and LNG, via “virtual” natural gas pipelines and interconnects; sells U.S. federal, state and local government credits it generates by selling RNG in the form of CNG and LNG as a vehicle fuel, including Renewable Identification Numbers (“RIN Credits” or “RINs”) under the federal Renewable Fuel Standard Phase 2 and credits under the California, Oregon, and Washington Low Carbon Fuel Standards (collectively, “LCFS Credits”); and obtains federal, state and local tax credits, grants and incentives. Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries, and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s consolidated financial position as of September 30, 2025, results of operations, comprehensive loss, and stockholders’ equity for the three and nine months ended September 30, 2024 and 2025, and cash flows for the nine months ended September 30, 2024 and 2025. All intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2024 and 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any other interim period or any future year. Certain information and disclosures normally included in the notes to consolidated financial statements have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), but the resultant disclosures contained herein are in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as they apply to interim reporting. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements as of and for the year ended December 31, 2024 that are included in the Company’s Annual Report on Form 10-K filed with the SEC on February 24, 2025. 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 amounts reported in the accompanying condensed consolidated financial statements and these notes. Actual results could differ from those estimates and may result in material effects on the Company’s operating results and financial position. Significant estimates made in preparing the accompanying condensed consolidated financial statements include (but are not limited to) those related to revenue recognition, fair value measurements, goodwill and long-lived asset valuations and impairment assessments, income tax valuations, stock-based compensation expense and stock-based sales incentive charges. Amazon Warrant The Amazon Warrant (defined in Note 14) is accounted for as an equity instrument and measured in accordance with Accounting Standards Codification (“ASC”) 718, Compensation – Stock Compensation. This instrument is classified in the condensed consolidated statements of operations in accordance with ASC 606, Revenue from Contracts with Customers, which states that for awards granted to a customer that are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price. To determine the fair value of the Amazon Warrant in accordance with ASC 718, the Company used the Black-Scholes option pricing model, which is based in part on assumptions that require management to use judgment. Based on the fair value of the award, the Company determines the amount of non-cash stock-based sales incentive charges on the customer’s pro-rata achievement of vesting conditions, which is recorded as a reduction of revenue in the condensed consolidated statements of operations. See Note 14 for additional information. Tourmaline Joint Development In April 2023, the Company and Tourmaline Oil Corp. (“Tourmaline”) announced a CAD $70 million Joint Development Agreement to build and operate a network of CNG stations along key highway corridors across Western Canada. Under a 50-50 shared investment, the Company and Tourmaline expect to construct and commission up to 20 CNG fueling stations over the next five years, allowing heavy-duty trucks and other commercial transportation fleets that operate in the area to transition to the use of CNG, a lower carbon alternative to gasoline and diesel. Costs associated with station construction and profit and loss arising from station operation are shared 50-50 between the Company and Tourmaline. This arrangement between the Company and Tourmaline to jointly develop, build and operate CNG fueling stations is accounted for in accordance with ASC 808, Collaborative Arrangements, which states that (1) costs incurred and revenue generated from transactions with third parties be separately recorded by each participant in its own financial statements, (2) the participant who is deemed to be the principal for a given transaction under ASC 606, Revenue from Contracts with Customers, will record the transaction on a gross basis in its financial statements, and (3) payments between participants that are within the scope of other authoritative accounting literature on income statement classification shall be accounted for using the relevant provisions of that literature. If the payments are not within the scope of other authoritative accounting literature, then the income statement classification for the payments shall be based on an analogy to authoritative accounting literature or if there is no appropriate analogy, a reasonable, rational, and consistently applied accounting policy election. The Company determined that it is the principal for the revenue generated from third parties under this collaborative arrangement with Tourmaline in accordance with ASC 606; as such, the associated revenue and cost of sales generated and incurred are recognized on a gross basis in the condensed consolidated statements of operations. Net participation of profit and loss owed to or from Tourmaline is recorded as an increase or decrease to cost of sales, respectively, as the transaction is not deemed to be with a customer within the scope of ASC 606. Capitalized station costs are presented at half of the total development and construction costs in the condensed consolidated balance sheets, corresponding to the Company’s 50% ownership in the shared assets. Impairment of Goodwill and Long-Lived Assets Goodwill represents the excess of costs incurred over the fair value of the net assets of acquired businesses. The Company assesses its goodwill using either a qualitative or quantitative approach to determine whether it is more likely than not that the fair value of the Company’s single reporting unit is less than its carrying value. Judgment is required when applying the goodwill impairment test, including, among other considerations, the identification of reporting unit(s), the assessment of qualitative factors, and the estimation of fair value of a reporting unit in the quantitative approach. The Company has determined that it represents one single reporting unit for the purpose of the goodwill impairment test. The goodwill impairment test is performed annually on October 1st, or more frequently if facts or circumstances change that would indicate that the carrying amount of the Company may be impaired. ​ During the first quarter of 2025, it was determined that the Company had a sustained decline in its share price. This circumstance warranted an interim impairment test as it was determined that it was more likely than not that a goodwill impairment loss had been incurred. ​ A quantitative goodwill impairment analysis was performed as of March 31, 2025. The quantitative goodwill impairment test estimated the fair value of the Company’s single reporting unit based on its market value of invested capital plus a market participant acquisition premium derived from recent merger and acquisition transactions in comparable industry and market sectors as those in which the Company operates. The carrying value exceeded fair value, by an amount greater than the carrying value of goodwill. ​ Accordingly, a goodwill impairment loss for the Company’s single reporting unit was recognized in the amount of $64.3 million, in the period ended March 31, 2025, which comprised the total amount of goodwill of the Company before giving effect to the impairment and is recognized as “Impairment of goodwill” on the consolidated statement of operations for the nine month period ended September 30, 2025. ​ As a result of this impairment loss, the Company has no goodwill remaining as of September 30, 2025. ​ Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-01, Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards. This ASU improves U.S. GAAP by adding an illustrative example to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether profits interest and similar awards should be accounted for in accordance with Topic 718. The ASU is effective for annual periods, including interim periods within those years, beginning after December 15, 2024, with early adoption allowed. The Company adopted this new ASU in the first quarter of 2025. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements and related disclosures. In August 2023, the FASB issued ASU 2023-05, Business Combinations – Joint Venture Formations (Topic 805-60): Recognition and Initial Measurement, which requires joint venture entities to initially measure all contributions received and liabilities assumed upon its formation at fair value. The guidance is applicable to joint venture entities with a formation date on or after January 1, 2025. The Company adopted the provisions of this ASU as of January 1, 2025. The adoption of this ASU did not have an impact on the Company’s consolidated financial statements as the Company has not formed any new joint ventures in the period. The Company will apply this ASU prospectively to future joint ventures. Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures. This ASU enhances annual income tax disclosures by requiring entities to disclose specific categories and greater disaggregation of information in the rate reconciliation table and income taxes paid disaggregated by jurisdiction. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, with early adoption permitted. The Company will adopt this ASU for the year ending December 31, 2025. 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 disclosure of specified information about certain costs and expenses in the notes to financial statements at interim and annual reporting periods. The ASU is effective for all public business entities for annual periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. ​ In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which eliminates accounting consideration of software project development stages and clarifies the threshold applied to begin capitalizing costs. The ASU is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years, and permits prospective, modified prospective, or retrospective adoption. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. ​ In September 2025, the FASB issued ASU 2025-07, “Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract.” This ASU excludes from derivative accounting non-exchange-traded contracts with underlyings based on operations or activities specific to one of the parties to the contract. This guidance is effective for fiscal years and interim periods beginning after December 15, 2026, with early adoption permitted. These requirements may be applied prospectively or on a modified retrospective basis through a cumulative-effect adjustment to the opening balance of retained earnings. We do not expect the adoption of ASU 2025-07 to have a material impact on our consolidated financial statements and related disclosures. ​
