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 consolidated balance sheets as of June 30, 2024 December 31, 2023 Lumo Sweden are continuing to liquidate their remaining receivables and settle any remaining liabilities.

All assets and liabilities of Lumo Finland remain with Lumo Finland, in which Genie retains its equity ownership interest, however, the management and control of Lumo Finland were transferred to the Lumo Administrators. Since the Company lost control of the management of Lumo Finland in favor of the Lumo Administrators, the accounts of Lumo Finland were deconsolidated effective November 9, 2022 Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Discontinued Operations in the United Kingdom In October 2021 Following the termination of the contract with Shell, Orbit filed a petition with the High Court of Justice Business and Property of England and Wales (the “Court”) to declare Orbit insolvent based on the Insolvency Act of 1986 November 29, 2021 December 1, 2021 The Company determined that the discontinued operations of Orbit represented a strategic shift that would have a major effect on the Company's operations and financial statements. Since the appointment of the Orbit Administrators, the Company has accounted for these businesses as discontinued operations and accordingly, has presented the results of operations and related cash flows as discontinued operations. Since the Company lost control of the management of Orbit in favor of the Orbit Administrators, the accounts of Orbit were deconsolidated effective December 1, 2021 On November 21, 2023 November 28, 2023 November 28, 2023 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. Unseasonable 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 48.1% and 39.7% of GRE’s natural gas revenues for the relevant years were generated in the first quarters 2023 2022 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 32.5 % 30.5 % of 2023 and 2022 , respectively . 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.

Revenue Recognition
Revenue Recognition	Note 4 —Revenue Recognition Revenue from the single performance obligation to deliver a unit of electricity and/or natural gas is recognized as the customer simultaneously receives and consumes the benefit. GRE records unbilled revenues for the estimated amount customers will be billed for services rendered from the time meters were last read to the end of the respective accounting period. The unbilled revenue is estimated each month based on available per day usage data, the number of unbilled days in the period and historical trends. Incumbent utility companies in most of the service territories in which GRE's REPs operate offer purchase of receivables, or POR, and participate in POR programs for a majority of their receivables. The Company estimates variable consideration related to its rebate programs using the expected value method and a portfolio approach. The Company’s estimates related to rebate programs are based on the terms of the rebate program, the customer’s historical electricity and natural gas consumption, the customer’s rate plan, and a churn factor. Taxes that are imposed on the Company’s sales and collected from customers are excluded from the transaction price. Revenue from sales of solar panels are recognized at a point in time following the transfer of control of the solar panels to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. For sales contracts that contain multiple performance obligations, such as the shipment or delivery of solar modules, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product is transferred to the customer, in satisfaction of the corresponding performance obligations. Revenues from sales of solar panels are included in other revenues in the consolidated statements of operations. Genie Solar enters into contracts to identify, develop, and in some cases operate solar generation sites to provide solar electricity to its customers. Obligations under solar project contracts consist of a series of tasks and components and accordingly are accounted for as multiple performance obligations. Because the Company’s performance creates and enhances assets that are controlled by and specific to customers, the Company recognizes construction services revenue over time. Revenue for these performance obligations is recognized using the input method based on the cost incurred as a percentage of total estimated contract costs. Due to the significance of the costs associated with solar panels to the total project, our judgment on when such costs should be included in the measure of progress has a material impact on revenue recognition. Contract costs include all direct material and labor costs related to contract performance. Revenues from sales of solar panels and solar panel projects are included under the Other Revenues in the consolidated statements of operations. Energy generation revenue is earned from both the sale of electricity generated from operating solar projects and the sale of Solar Energy Credits ("SRECs") which are included in the Other Revenues in the consolidated statement of operations. Revenue from energy generation is recognized when the Company satisfies the performance obligation, which occurs at the time of the delivery of electricity at the contractual rates. The Company applies for and receives SRECs in certain jurisdictions for power generated by solar energy systems it owns. There are no direct costs allocated to SRECs upon generation. The Company typically sells SRECs to different customers from those purchasing the energy. The sale of each SREC is a distinct performance obligation satisfied at a point in time and that the performance obligation related to each SREC is satisfied when each SREC is delivered to the customer. Revenues from commissions from selling third-party products to customers, entry and other fees from the energy brokerage are recognized at the time the performance obligation is met. The Company's contacts with customers for commission revenue contain a single performance obligation and are satisfied at a point in time. The Company recognizes the incremental costs of obtaining a contract with a customer as an asset if it expects the benefit of those costs to be longer than one one Disaggregated Revenues The following table shows the Company’s revenues disaggregated by pricing plans offered to customers: Electricity Natural Gas Other Total (in thousands) Three Months Ended June 30, 2024 Fixed rate $ 47,207 $ 3,295 $ — $ 50,502 Variable rate 31,094 5,119 — 36,213 Other — — 3,981 3,981 Total $ 78,301 $ 8,414 $ 3,981 $ 90,696 Three Months Ended June 30, 2023 Fixed rate $ 47,625 $ 2,983 $ — $ 50,608 Variable rate 32,574 5,992 — 38,566 Other — — 4,289 4,289 Total $ 80,199 $ 8,975 $ 4,289 $ 93,463 Six Months Ended June 30, 2024 Fixed rate $ 99,303 $ 10,724 $ — $ 110,027 Variable rate 68,394 20,088 — 88,482 Other — — 11,875 11,875 Total $ 167,697 $ 30,812 $ 11,875 $ 210,384 Six Months Ended June 30, 2023 Fixed rate $ 77,130 $ 8,598 $ — $ 85,728 Variable rate 77,556 27,302 — 104,858 Other — — 8,153 8,153 Total $ 154,686 $ 35,900 $ 8,153 $ 198,739 Fixed and variable rate revenues are from GRE.

Investment in Equity Method Investees [Abstract]
Investments	Note 9 e Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. The Company periodically evaluates its equity method investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded, and a new basis in the investment is established. For equity securities without readily determinable fair values, the Company elected to measures the investments using net assets value, as a practical expedient. These investments are valued based on the most recent available information. In determining the value of the investment, the Company considers whether adjustments to the net asset values are necessary in certain circumstances in which management is aware of material events that affect the value of the investments during the intervening perio d. Changes in fair value are recognized in “g ain (loss) on marketable equity securities and investments For equity securities that do not have a readily determinable fair value and do not r ep ort net asset value Equity investments consist of the following: Location in Balance Sheet Measurement June 30, 2024 December 31, 2023 (in thousands) Rafael Holdings , Inc.
