Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Note 1—Basis of Presentation and Business Changes and Development The accompanying unaudited condensed consolidated financial statements of Genie Energy Ltd. and its subsidiaries (the “Company” or “Genie”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. The consolidated balance sheet at December 31, 2025 has been derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Form 10-K"), as filed with the U.S. Securities and Exchange Commission (the “SEC”). The Company owns 100% of Genie Retail Energy (“GRE”) and varied interests in entities that comprise the Genie Renewables ("GREW") segment. GRE owns and operates retail energy providers (“REPs”), including IDT Energy (“IDT Energy”), Residents Energy (“Residents Energy”), Town Square Energy and Town Square Energy East (collectively, "TSE"), Southern Federal Power ("Southern Federal"), Mirabito Natural Gas (“Mirabito”) and Evergreen Gas & Electric (“Evergreen”). The majority of GRE's REP customers are located in the Eastern and Midwestern United States and Texas. GREW primarily consists of a 91.5% interest in Diversegy, an energy procurement advisor for industrial, commercial and municipal customers, a 95.5% interest in Genie Solar, an integrated solar energy company that develops, constructs and operates utility-scale solar energy projects, a 93.8% interest in CityCom Solar, a marketer of community solar and alternative products and services complementary of its energy offerings, a 72.2% interest in Roded Recycling ("Roded"), a producer of high-grade plastic pallets from recycled materials and a 57.0% interest in Able Minds ABA LLC ("Able Minds"), a provider of expert applied behavioral analysis therapy for children with autism. One Big Beautiful Bill Act On July 4, 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted into law. The law accelerates the expiration of the federal investment tax credit on solar projects, effective for projects going online after December 31, 2027. In light of this law, the Company evaluated the financial viability of all its solar projects and its qualification for the federal solar investment tax credits and the resulting impact on the viability of such projects. The Company identified several projects that will be discontinued and assessed the values of the related assets at the lower of fair values less cost to sell and net book value. The Company also identified several assets, including definite life intangibles and solar panel inventories and assessed the carrying values for impairment. Discontinued Operations in Finland and Sweden In the third quarter of 2022, the Company decided to discontinue the operations of Lumo Energia Oyj ("Lumo Finland") and Lumo Energi AB ("Lumo Sweden"). The Company accounts for these businesses as discontinued operations, and accordingly, presents the results of operations and related cash flows as discontinued operations. The results of operations and related cash flows are presented as discontinued operations for all periods. Any remaining assets and liabilities of the discontinued operations are presented separately and reflected within assets and liabilities from discontinued operations in the accompanying condensed consolidated balance sheets as of June 30, 2026 and December 31, 2025. Lumo Sweden is continuing to liquidate their remaining assets and settle any remaining liabilities. Seasonality and Weather; Climate Change and Volatility in Pricing The weather and the seasons, among other things, affect GRE’s revenues. Weather conditions have a significant impact on the demand for natural gas used for heating and electricity used for heating and cooling. Typically, colder winters increase demand for natural gas and electricity, and hotter summers increase demand for electricity. Milder winters or summers have the opposite effect. Unseasonal temperatures in other periods may also impact demand levels. Natural gas revenues typically increase in the first quarter due to increased heating demands and electricity revenues typically increase in the third quarter due to increased air conditioning use. Approximately 43.3% and 43.0% of GRE’s natural gas revenues for the relevant years were generated in the first quarters of 2025 and 2024, respectively, when demand for heating was highest. Although the demand for electricity is not as seasonal as natural gas (due, in part, to usage of electricity for both heating and cooling), approximately 30.7% and 28.7% of GRE’s electricity revenues were generated in the third quarters of 2025 and 2024, respectively. GRE’s REPs’ revenues and operating income are subject to material seasonal variations, and the interim financial results are not necessarily indicative of the estimated financial results for the full year. In addition, extraordinary weather has and can lead to extreme spikes in the prices of wholesale electricity and natural gas in markets where GRE and other retail providers purchase their supply, or in challenges to the grid or supply markets in affected areas. Such events could have material impacts on our margins and operations. In addition to the direct physical impact that climate change may have on the Company's business, financial condition and results of operations because of the effect on pricing, demand for our offerings and/or the energy supply markets, we may also be adversely impacted by other environmental factors, including: (i) technological advances designed to promote energy efficiency and limit environmental impact; (ii) increased competition from alternative energy sources; (iii) regulatory responses aimed at decreasing greenhouse gas emissions; and (iv) litigation or regulatory actions that address the environmental impact of our energy products and services. Reclassifications Certain accounts in the prior period condensed consolidated financial statements have been reclassified to conform to the presentation of the current year condensed consolidated financial statements. These reclassifications had no effect on the previously reported operating results.
