Description of Business and Summary of Significant Accounting Policies
Description of Business and Summary of Significant Accounting Policies	Note 1 — Description of Business and Summary of Significant Accounting Policies Description of Business Genie Energy Ltd. (“Genie”), a Delaware corporation, was incorporated in January 2011. Genie owns 99.5% of Genie Energy International Corporation (“GEIC”), which owns 100% of Genie Retail Energy (“GRE”), and 95.5% of Genie Renewables. In the third quarter of 2022, the company ceased to operate a former segment, GRE International. GRE, owns and operates retail energy providers (“REPs”), including IDT Energy, Inc. (“IDT Energy”), Residents Energy, LLC (“Residents Energy”), Town Square Energy, LLC and Town Square Energy East, LLC (collectivity, “TSE”), Southern Federal Power LLC ("Southern Power") and Mirabito Natural Gas (“Mirabito”). GRE's REPs' businesses resell electricity and natural gas to residential and small business customers primarily in the Eastern and Midwestern United States and Texas. Genie Renewables holds Genie Solar Energy ("Genie Solar"), an integrated solar energy company and a 92.8% interest in CityCom Solar, a marketer of community solar energy solution, Diversegy LLC ("Diversegy"), a broker for commercial customers, and GRE's 60.0% interest in Prism Solar Technology, Inc. ("Prism"), a solar solutions company that is engaged in the manufacturing of solar panels, solar installation design and solar energy project management. Discontinued operations in Finland and Sweden Previously, the Company had a third segment, Genie Retail Energy International, which supplied electricity to residential and small business customers in Scandinavia. However, The Company determined that the discontinued operations in Finland and Sweden represented a strategic shift that will have a major effect on the Company's operations and financial statements. 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. The results of operations and related cash flows are presented as discontinued operations for all periods presented. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 and 2021. Lumo Finland and Lumo Sweden will continue to liquidate their remaining receivables and settle any remaining liabilities. Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a separate segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Discontinued Operations in United Kingdom In third quarter of 2021, the natural gas and energy market in the United Kingdom deteriorated which prompted the Company to start the process of orderly withdrawal from the United Kingdom market. In October 2021, as part of the orderly exit process from the United Kingdom market, Orbit and Shell U.K. Limited ("Shell") agreed to terminate the exclusive supply contract between them. As part of the termination agreement, Orbit was required to unwind all physical forward hedges with Shell which resulted in net cash proceeds after settlement of all related liabilities with Shell. 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 The Company determined that the discontinued operations in the United Kingdom represented a strategic shift that will have a major effect on the Company's operations and financial statements. Since the appointment of the 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. The results of operations and related cash flows are presented as discontinued operations for all periods presented. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 and 2021 Energy Price Volatility in Japan and Texas In January 2021, weather volatility and the lack of adequate gas reserves significantly increased the price of energy at Japan Electric Power Exchange ("JEPX") for an extended period of time. The spike in demand associated with this situation, exposed Genie Japan to unexpected cost increases. Genie Japan incurred approximately $2.5 million in additional costs related to the price increases, which were included in the cost of revenue in the first quarter of 2021. In February of 2021, the State of Texas experienced unprecedented cold weather and snow, which was named Winter Storm Uri. With the grid overtaxed due to demand and weather-related reduced supply and rolling blackouts being enforced, by order of the Electricity Reliability Council of Texas ("ERCOT"), real-time commodity prices during the crisis escalated significantly. Although GRE's commitment for their customers in Texas was hedged for foreseen winter weather conditions, the market conditions exposed the Company to significant unexpected cost increases. In the year ended December 31, 2021, GRE recognized approximately $13.0 million in additional costs related to the situation, which were included in the cost of revenue in the consolidated statements of operation. In June 2021, the legislature of the State of Texas passed House Bill (“HB ”) which includes certain provisions for financing certain costs associated with electric markets caused by Winter Storm Uri. Pursuant to HB , categories of charges associated with Winter Storm Uri are to be securitized and the proceeds of the securitization will be provided to the load serving entities who originally incurred the charges. Under HB , the Company is entitled to recover a portion of the costs incurred from the effect of Winter Storm Uri with a calculated range of $ million to $ million. In the second quarter of , the Company recorded a reduction in cost of revenues of $ million. In September 2021, the Public Utility Commission of Texas ("PUC") approved the Debt Obligation Order to grant ERCOT's application for a debt financing mechanism to pay for certain costs associated with Winter Storm Uri. Under the Debt Obligation Order, the amount that the Company is entitled to recover increased to approximately $3.4 million. In the third quarter of 2021, the Company recorded an additional reduction in the cost of revenues of $1.9 million for an aggregate amount of $3.4 million for the year ended December 31, 2021. In June 2022, the Company received a $ 3.5 million refund related to the cost of Winter Storm Uri. Seasonality and Weather 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 and/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. Approximately39.7 and 44.5% of GRE’s natural gas revenues for the relevant years were generated in the first quarters of 2022 and 2021, 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), approximately30.5 and 30.3% of GRE’s electricity revenues for the relevant years were generated in the third quarters of 2022 and 2021, 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. Basis of Consolidation The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries and the variable interest entity in which the Company is the primary beneficiary (see Note 14). All significant intercompany accounts and transactions between the consolidated entities are eliminated. Equity Method Investments 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. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates affecting amounts reported or disclosed in the consolidated financial statements include revenues, marketable equity securities and other investments, accounts receivables, allowances for doubtful accounts receivable, net realizable value of inventories, valuation of intangible assets, depreciation and amortization periods for long-lived assets, valuation allowances recorded against deferred tax assets, the valuation of stock-based compensation, valuation of derivative instruments, valuation of debt instruments and loss contingencies. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the current circumstances. Actual results may differ from those estimates. Revenue Recognition Revenues from the Sale of Electricity and Natural Gas 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. Variable quantities in requirements contracts are considered to be options for additional goods and services because the customer has a current contractual right to choose the amount of additional distinct goods to purchase. GRE and Genie Japan (prior to its sale in May 2021) record 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, 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 year. The Company determined that certain sales commissions to acquire customers meet the requirements to be capitalized. For GRE, the Company applies a practical expedient to expense costs as incurred for sales commissions to acquire customers as the period would have been one year or less. Revenues from Sale of Solar Panels Revenues 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.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported in the consolidated balance sheet that equals the total of the same amounts reported in the consolidated statement of cash flows: December 31, 2022 2021 (in thousands) Cash and cash equivalents $ 98,571 $ 93,568 Restricted cash—short-term 6,007 6,657 Total cash, cash equivalents, and restricted cash $ 104,578 $ 100,225 Restricted cash—short-term includes amounts set aside in accordance with the Amended and Restated Preferred Supplier Agreement with BP Energy Company (“BP”) (see Note Note Included in the cash and cash equivalents as of is cash received from Lumo Sweden ( see Note 2 ) Included in the cash and cash equivalents as of December 31, 2021 is cash received from Orbit Energy (see Note 2 Marketable Equity Securities and Other Investment Marketable equity securities that are traded in the public market are carried at fair value using the quoted price at the end of each reporting period. Changes in the fair value are recorded as unrealized gains or losses on investments in the consolidated statements of operations. Trade Accounts Receivable, Net Trade accounts receivable, net is reported in the balance sheet as gross outstanding amounts adjusted for doubtful accounts. Inventories Inventory consists of natural gas, renewable energy credits and solar panels. Natural Gas Natural gas inventory is stored at various third parties’ underground storage facilities and is stated at lower of cost or net realizable value. The Company’s natural gas inventory was valued at weighted average cost, which was based on the purchase price of the natural gas and the cost to transport, plus or minus injections or withdrawals. Renewable Energy Credits GRE must obtain a certain percentage or amount of its power supply from renewable energy sources in order to meet the requirements of renewable portfolio standards in the states in which it operates. This requirement may be met by obtaining renewable energy credits that provide evidence that electricity has been generated by a qualifying renewable facility or resource. GRE holds renewable energy credits for both sale and use, and treats the credits as a government incentive to encourage the construction of renewable power plants. Renewable energy credits are valued at the lower of cost and net realizable value. Gains and losses from the sale of renewable energy credits are recognized in cost of revenues when the credits are transferred to the buyer. Solar Panels Inventories related to solar panels are stated at the lower of cost or net realizable value. The cost is determine using the first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor, and indirect manufacturing costs. The Company regularly reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. The Company also regularly evaluates the quantities and values of inventories, in light of current market conditions and trends among other factors and records write-downs for any quantities in excess of demand or for any obsolescence. This evaluation considers the use of modules in the systems business, expected demand, anticipated sales prices, strategic raw material requirements, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, product merchantability, and other factors. Market conditions are subject to change, and actual consumption of our inventory could differ from forecasted demand. Inventories consisted of the following: December 31, 2022 2021 (in thousands) Natural gas $ 3,302 $ 1,891 Renewable credits 10,531 15,610 Solar panels 1,881 219 Total inventories $ 15,714 $ 17,720 Long-lived Assets Property, plant and equipment - net is stated at historical cost less accumulated depreciation and any impairment. The Company provides for depreciation using a straight-line method over estimated useful life of the assets. Any leasehold improvements are amortized over the lesser of the lease term or the useful life. The cost of major additions and improvements are capitalized, while maintenance and repair costs that do not improve or extend the lives of the respective assets are charged to operations as incurred. The estimated useful life of property plant and equipment as follows: Years Machinery and equipment 2 - 9 Computer software and development 2 - 5 Computers and computer hardware 2 - 5 Office equipment and other 4 - 27 The fair value of patents and trademarks, non-compete agreements and customer relationships acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: patents and trademarks are amortized on a straight-line basis over a 10 to 20-year period; non-compete agreements are amortized on a straight-line basis 9-year term and licenses are amortized on a straight-line basis over a 10-year period. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests the recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss based on excess of carrying value over fair value of the assets. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material. Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to 1 year from the acquisition date. For each acquisition, the Company undertakes a detailed review to identify other intangibles assets and a valuation is performed for all such identified assets. The Company uses several market participant measures to determine estimated value. This approach includes consideration of similar recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible asset value that the Company acquired is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, non-compete agreements, trademarks, patents as well as licenses. If the actual results differ from the estimates, the amount recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expenses of finite-lived intangible assets. Goodwill and Indefinite Lived Intangible Assets Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite-lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The Company has 2 reportable segments with 3 underlying reporting units: GRE, GRE International, and Genie Renewables, which is comprised of Prism and Diversegy. The fair value of each reporting unit is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Calculating the fair value of the reporting units requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company performs its annual goodwill impairment test as of October 1. In reviewing goodwill for impairment, the Company has the option, for any or all of its reporting units that carry goodwill - to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (i.e. greater than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If the Company elects to perform a qualitative assessment and determines that an impairment is more likely than not, the Company is then required to perform the quantitative impairment test, otherwise no further analysis is required. The Company also may elect not to perform the qualitative assessment and, instead, proceed directly to quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether the Company chooses to perform the qualitative assessment or proceeds directly to the quantitative impairment test. T he determination of the fair value of our reporting units is based on an income approach that utilizes discounted cash flows for each reporting 3 820, Fair Value Measurements and Disclosure Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and on the type of hedging relationship. Due to the volatility of electricity and natural gas prices, GRE enters into futures contracts, swaps and put and call options as hedges against unfavorable fluctuations in market prices of electricity and natural gas and to reduce exposure from price fluctuations. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the futures contracts, swaps and put and call options are recorded at fair value as current and noncurrent assets or liabilities and any changes in fair value are recorded in “Cost of revenues” in the consolidated statements of operations. In addition to the above, GRE utilizes forward physical delivery contracts for a portion of their purchases of electricity and natural gas, which are defined as commodity derivative contracts. Using the exemption available for qualifying contracts, GRE applies the normal purchase and normal sale accounting treatment to its forward physical delivery contracts, thereby these contracts are not adjusted to fair value. GRE also applies the normal purchase and normal sale accounting treatment to forward contracts for the physical delivery of electricity in nodal energy markets that result in locational marginal pricing charges or credits, since this does not constitute a net settlement, even when legal title to the electricity is conveyed to the ISO during transmission. Accordingly, GRE recognizes revenue from customer sales, and the related cost of revenues, at the contracted price, as electricity and natural gas is delivered to retail customers. Shipping and Handling Fees and Costs Amounts billed to customers for shipping and handling are included in revenues. The related minimal amount of shipping and freight charges incurred by the Company are included in cost of goods sold. Distribution and handling costs of $0.1 million were recorded in selling, general and administrative expense for each of the years ended December 31, 2022 and 2021, respectively. Foreign Currency Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the consolidated statements of operations. Advertising Expense Cost of advertising for customer acquisitions is charged to selling, general and administrative expenses in the period in which it is incurred. In each of the years ended December 31, 2022 and 2021, advertising expenses included in selling, general and administrative expenses was $7.0 million. Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense. Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred. Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock issued and outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended December 31, 2022 2021 (in thousands) Basic weighted-average number of shares $ 25,629 $ 25,879 Effect of dilutive securities Shares underlying stock options and warrants 561 390 Non-vested restricted Class B common stock 176 47 Diluted weighted-average number of shares $ 26,366 $ 26,316 The following shares were excluded from the diluted earnings per share computations: Year ended December 31, (in thousands) 2022 2021 Shares underlying stock options — 126 Non-vested deferred stock units 210 580 Stock options were excluded from the diluted earnings per share computation in the year ended December 31, 2021 because the exercise prices of the stock options were greater than the average market prices of the Company's Class B common stock during the period. Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market condition for vesting of those deferred stock units was not met as of December 31, 2022 or 2021. Stock-Based Compensation The Company recognizes compensation expense for grants of stock-based awards to its employees based

Discontinued Operations and Divestiture	Note 2 Lumo Finland and Lumo Sweden Operations As a result of the sustained volatility in the energy markets in Europe, in July 2022, the Company initiated a plan to dispose of certain assets and liabilities of Lumo Finland and Lumo Sweden. From July 13, 2022 to July 19, 2022, the Company entered into a series of transactions to sell most of the electricity swap instruments held by Lumo Sweden for a gross aggregate amount of €41.1 million (equivalent to approximately $41.4 million at the dates of the transactions) before fees and other costs. The sale price is expected to be settled monthly based on the monthly commodity volume specified in the instruments from September 2022 34.2 35.8 In July 2022, Lumo Sweden entered into a transaction to transfer, effective August 5, 2022, its customers to a third party for a nominal consideration. In August 2022, Lumo Finland entered into a transaction to transfer its variable rate customers to a third party for €1.9 million (equivalent to $2.0 million) and terminated the contracts of fixed rate customers. The Company determined that exiting operations in Lumo Finland and Lumo Sweden represented a strategic shift that will have a major effect on the Company's operations and financial statements and accordingly, the results of operations and related cash flows are presented as discontinued operations for all periods presented. The assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 and 2021. Lumo Finland and Lumo Sweden will continue to liquidate their remaining receivables and settle any remaining liabilities. In November 2022, Lumo Finland declared bankruptcy and the administration of Lumo Finland was transferred to an administrator ("Lumo Administrators"). All assets and liabilities of Lumo Finland remain with Lumo Finland, in which Genie retains its 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 Orbit were deconsolidated effect November 9, 2022. The following table represents summarized balance sheet information of assets and liabilities of the discontinued operations of Lumo Finland and Lumo Sweden: December 31, 2022 December 31, 2021 (in thousands) Assets Cash $ 1,503 $ 1,924 Trade accounts receivable, net — 11,048 Fair value of derivative contracts—current — 12,826 Receivables from the settlement of the derivative contract—current 23,351 4,655 Other current assets — 2,784 Current assets of discontinued operations $ 24,854 $ 33,237 Receivables from the settlement of the derivative contract—noncurrent $ 12,689 $ — Other noncurrent assets 3,616 1,172 Noncurrent assets of discontinued operations $ 16,305 $ 1,172 Liabilities Accounts payable $ 5 $ 19,013 Accrued expenses — 1,518 Income taxes payable 10,894 280 Other current liabilities 37 393 Current liabilities of discontinued operations $ 10,936 $ 21,204 Deferred tax liabilities $ 686 $ — Other noncurrent liabilities — 438 Noncurrent liabilities of discontinued operations $ 686 $ 438 The summary of the results of operations of the discontinued operations were as follows: Year ended December 31, 2022 2021 (in thousands) Total revenues $ 25,247 $ 40,456 Cost of revenues (8,357 ) 27,233 Gross (loss) profit 33,604 13,223 Selling, general and administrative expenses 5,190 4,222 Loss from operations 28,414 9,001 Gain from the settlement of assets 7,482 — Loss from deconsolidation of subsidiary (314 ) — Foreign exchange gains 2,241 — Other income 383 — Net income before taxes 38,206 9,001 Income taxes 7,761 1,267 Income from discontinued operations, net of taxes $ 30,445 $ 7,734 The following table presents a summary of cash flows of the discontinued operations: Year Ended December 31, 2022 2021 (in thousands) Operating Activities Net income $ 30,445 $ 7,734 Non-cash items (8,370 ) 1,941 Changes in assets and liabilities (7,395 ) ( ) Cash flows used in operating activities of discontinued operation $ 14,680 $ ( ) In furtherance of the Company’s exit from retail energy markets in Finland and Sweden and to facilitate the maximization of value at Lumo Sweden, restricted Class B common stock of the Company, which will vest ratably from November 2022 May 2025 % to % and increased from % to % in Lumo Sweden. The assets and liabilities of Lumo Finland and Lumo Sweden were included in GRE International segment. United Kingdom Operations On July 17, 2017, the Company’s subsidiary, Genie Energy UK Ltd. (“GEUK”), entered into a definitive agreement with Energy Global Investments Pty Ltd (“EGC”) to launch Shoreditch Energy Limited (“Shoreditch”), a joint venture to offer electricity and natural gas service to residential and small business customers in the U.K., under the trade name Orbit Energy. Prior to October 8, 2020, the Company owns 77.0 On In , the natural gas and energy market in the U.K. deteriorated which prompted the Company to start the process of orderly withdrawal from the U.K. market. In October 2021, as part of the orderly exit process, Orbit and Shell U.K. Limited ("Shell") agreed to terminate the exclusive supply contract between them. As part of the termination agreement, Orbit was required to unwind all physical forward hedges with Shell which resulted in net cash proceeds after settlement of all related liabilities with Shell. 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. On November 29, 2021, the Court declared Orbit insolvent, revoked Orbit's license to supply electricity and natural gas in the United Kingdom, ordered the current customers to be transferred to “supplier of last resort” and transfer the administration of Orbit to Administrators effective December 1, 2021. All of the customers of Orbit were transferred to a third-party supplier effective December 1, 2021 as ordered by the Court. All assets and liabilities of the Orbit, including cash and receivables remain with Orbit and the management and control of which was transferred to Administrators. The Company expects that the administration of Orbit will be completed in 2023. In the fourth quarter of 2021, Orbit transferred to GEIC a net amount of $49.7 million from the proceeds of the settlement of the contact with Shell which is included in cash and cash equivalents in the consolidated balance sheet as of December 31, 2021. In January 2022, the Company transferred $21.5 million to the Administrators of Orbit Energy to fund the settlement of the expected remaining liabilities of Orbit of $30.8 million, which were included in the current liabilities of discontinued operations in the consolidated balance sheet as of December 31, 2021 . In February 20 22, the Compan On February 24, 2022, the Administrators filed a petition under Chapter 15 of the U. In the second quarter of 2022, the Administrators filed an application to transfer the funds back to the Administrators’ control in the U.K. Subject to certain representations and expectations regarding use and application of the funds to efficiently and expeditiously pay off creditors and bring a timely close to the insolvency administration, the Company decided not to oppose the application, and the $28.3 million was transferred to the account of the Administrator. In August 2022, the Administrator paid the Company a partial return of its interest in Orbit of £4.6 million (equivalent to $5.4 million). The Company believes that the funds remaining with the Administrators are more than sufficient to pay any remaining creditors of Orbit (with any surplus, which the Company expects to be significant, to be returned to the Company). The Company determined that exiting operations in the United Kingdom represented a strategic shift that will have a major effect on the Company's operations and financial statements and accordingly, the results of operations and related cash flows are presented as discontinued operations for all periods presented. As a result of loss of control, the Company deconsolidated Orbit effective December 1, 2021 and estimated the remaining liability related to its ownership of Orbit. The sum mary of results of operations of the discontinued operations for the year ended December 31, 2021 was as follows (in thousands): Total revenues $ 86,269 Cost of revenues 89,059 Gross (loss) profit ( ) Selling, general and administrative expenses 47,894 Impairment of assets 6,650 Loss from operations ( ) Gain from settlement of contract with supplier 69,120 Other loss ( ) Net income before taxes 10,854 Income taxes 6,884 Income from discontinued operations, net of taxes $ 3,970 The assets and liabilities of Orbit were included in GRE International segment. Divestiture of Genie Japan In March 2021, the Company initiated a p lan to sell certain assets and liabilities of Genie Japan. In the first quarter of 2021 , certain assets and liabilities of Genie Japan were reclassified as assets and liabilities held for sale and reported at lower of fair value less cost to sell and net book value. On April 26, 2021, the Company entered into an Equity Purchase Agreement ("Purchase Agreement") with Hanhwa Q Cells Japan Co., Ltd. ("Hanhwa"), pursuant to which, the Company agreed to sell its interest in Genie Japan for ¥570.0 million (equivalent to approximately $5.3 million at April 26, 2021) subject to certain terms and conditions set forth in the Purchase Agreement. On May 11, 2021, upon the terms and subject to the conditions of Purchase Agreement, the Company completed the divestiture of Genie Japan for an aggregate cash consideration of ¥570.0 million (equivalent to approximately $5.2 million at May 11, 2021). Hanhwa also assumed the outstanding balance of the loan payable of Genie Japan. The Company paid $ — The assets and liabilities divested which was previously classified as held for sale included the following: (in thousands) Cash $ 83 Trade accounts receivable 1,737 Prepaid and other current assets 391 Intangible (license) 540 Other noncurrent assets 296 Accounts payable (611 ) Accrued expenses and other current liabilities (588 ) Loans payable (1,372 ) Cumulative translation adjustment (181 ) Noncontrolling interest 114 Liabilities held for sale included in other current liabilities $ 409 The assets and liabilities of Genie Japan were included in GRE International segment.

The underlying asset in the Company’s put and call options is a forward contract. The Company’s swaps are agreements whereby a floating (or market or spot) price is exchanged for a fixed price over a specified period. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting this data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. Restricted cash — short-term, trade receivables, due to IDT Corporation, other current assets and other current liabilities. At December 31, 2022 2021 current assets, due to IDT Corporation, and other current liabilities approximated fair value. Other assets. At December 31, 2022 and 2021 approximated fair value.

Derivative Instruments
Derivative Instruments	Note 4 — Derivative Instruments The primary risk managed by the Company using derivative instruments is commodity price risk, which is accounted for in accordance with Accounting Standards Codification 815 — Derivatives and Hedging. Natural gas and electricity put and call options and swaps are entered into as hedges against unfavorable fluctuations in market prices of natural gas and electricity. The Company does not apply hedge accounting to these options or swaps, therefore the changes in fair value are recorded in earnings. By using derivative instruments to mitigate exposures to changes in commodity prices, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk.

The incremental borrowing rate is estimated to approximate the interest rate on a collateralized borrowing rate based on information available at the lease commencement date. ROU assets also include any prepaid lease payments and lease incentives. The lease terms include periods under options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Variable Interest Entity
Variable Interest Entity	Note 14 Citizens Choice Energy, LLC (“CCE”) is a REP that resells electricity and natural gas to residential and small business customers in the State of New York. The Company does not own any interest in CCE. Since 2011, the Company has provided CCE with substantially all of the cash required to fund its operations. The Company determined that it has the power to direct the activities of CCE that most significantly impact its economic performance and it has the obligation to absorb losses of CCE that could potentially be significant to CCE on a stand-alone basis.

Legal and Regulatory Proceedings
Legal and Regulatory Proceedings	Note 15 Legal Proceedings On February 18, 2020, named plaintiff Danelle Davis filed a putative class action complaint against Residents Energy and GRE in United States District of New Jersey alleging violations of the Telephone Consumer Protection Act, 47 U.S.C § 227 et seq. Although Residents Energy and GRE deny any wrongdoing in connection with the complaints, the parties settled the matter for a minimal amount which was included in selling general and administrative expenses in the first quarter of 2021. In addition to the matter disclosed above, the Company may from time to time be subject to legal proceedings that arise in the ordinary course of business. Although there can be no assurance in this regard, the Company does not expect any of those legal proceedings to have a material adverse effect on the Company’s results of operations, cash flows or financial condition. Agency and Regulatory Proceedings From time to time, the Company receives inquiries or requests for information or materials from public utility commissions or other governmental regulatory or law enforcement agencies related to investigations under statutory or regulatory schemes, and the Company responds to those inquiries or requests. The Company cannot predict whether any of those matters will lead to claims or enforcement actions or whether the Company and the regulatory parties will enter into settlements before a formal claim is made. State of Connecticut Public Utilities Regulatory Authority Town Square On September 19, 2018, the State of Connecticut Public Utilities Regulatory Authority (“PURA”) commenced an investigation into Town Square following customer complaints of allegedly misleading and deceptive sales practices on the part of Town Square. The Connecticut Office of Consumer Counsel subsequently joined in the investigation. On June 17, 2020, PURA notified Town Square that it was advancing its investigation by assigning Prosecutorial staff for the purpose of investigating Town Square’s compliance with licensed electric supplier billing, marketing, and licensing requirements, and, if appropriate, facilitating settlement discussions among the parties. Although Town Square denies any basis for those complaints and any wrongdoing on its part, in July 2021, the parties settled the dispute. Pursuant to the terms of the settlement agreement, Town Square paid $0.4 million. Town Square has also agreed to voluntarily refrain from in-person marketing activities in Connecticut for a period of 15 months. For the years ended December 31, 2022 and 2021 $ Residents Energy In August 2020, Residents Energy began marketing retail energy services to Connecticut. For the year ended December 31, 2022, Residents Energy's gross revenues from sales in Connecticut was $0 million. During the fourth quarter of 2020, the enforcement division of PURA contacted Residents Energy concerning customer complaints received in connection with alleged door-to-door marketing activities in violation of various rules and regulations. On March 12, 2021, the enforcement division filed a motion against Resident Energy with the adjudicating body of PURA, seeking the assessment of $1.5 million in penalties, along with a suspension of license, auditing of marketing practices upon reinstatement and an invitation for settlement discussions. In June 2021, the parties settled the dispute. Pursuant to the terms of the settlement agreement, Residents Energy paid $0.3 million and volunteered to withdraw from the market in Connecticut for a period of 36 Other Informal Reviews or Investigations From time to time regulators may initiate informal reviews, compliance checks or issue subpoenas for information as means to evaluate the Company and its subsidiaries’ compliance with applicable laws, rule, regulations and practices. On October 25, 2019, the Office of the Attorney General of the State of Illinois ("IL AG") notified Residents Energy (by way of subpoena) that it is conducting an investigation to assess compliance with the Illinois Consumer Fraud and Deceptive Business Practices Act. The notice was issued in the form of a subpoena in the course of the foregoing. The Company, which has responded in part, has challenged the merits of the subpoena and investigation. Residents Energy denies any wrongdoing on its part. As of December 31, 2022, no claims or demands have been made against Residents Energy by the IL AG, and there is insufficient basis to deem any loss probable or to assess the amount of any possible loss. For the years ended December 31, 2022 and 2021, Resident Energy’s gross revenues from sales in Illinois was $32.7 million and $ 26.0 million, respectively. In response to certain customer complaints, the State of Maine Public Utility Commission (“MPUC”) has opened a review of the door to door marketing practices of Town Square. In August 2021, the parties settled the dispute without any obligation for payment by Town Square. In connection with the settlement, Town Square has agreed to voluntarily refrain from door-to-door marketing activities in Maine through June 30, 2023, and to voluntarily refrain from outbound telemarketing to obtain new residential customers for a period of six months, along with certain compliance procedures. For the years ended December 31, 2022 and 2021

Business Segment and Geographic Information	Note 18 The Company has two reportable business segments: GRE and Genie Renewables. Prior to In the third quarter 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. GRE owns and operates REPs, including IDT Energy, Residents Energy, TSE, Southern Federal and Mirabito. Its REP businesses resell electricity and natural gas to residential and small business customers in the Eastern and Midwestern United States and Texas. Genie Renewables designs, manufactures and distributes solar panels, offers energy brokerage and advisory services and also sells third-party products to customers. Corporate costs include unallocated compensation, consulting fees, legal fees, business development expenses and other corporate-related general and administrative expenses. Corporate does not generate any revenues, nor does it incur any cost of revenues. The Company’s reportable segments are distinguished by types of service, customers and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision-maker. The accounting policies of the segments are the same as the accounting policies of the Company as a whole. The Company evaluates the performance of its business segments based primarily on income (loss) from operations. There are no significant asymmetrical allocations to segments. Operating results for the business segments of the Company were as follows: GRE Genie Renewables Corporate Total (in thousands) Year ended December 31, 2022 Revenues $ 303,972 $ 11,567 $ — $ 315,539 Income (loss) from continuing operations 92,557 (3,528 ) (11,275 ) 77,754 Depreciation and amortization 336 49 — 385 Provision for doubtful accounts receivable 2,408 107 — 2,515 Stock-based compensation 952 — 2,016 2,968 Impairment of assets — — 2,066 2,066 Provision for (benefit from) income taxes 24,805 (684 ) (3,084 ) 21,037 Year ended December 31, 2021 Revenues $ 311,831 $ 7,508 $ 3,930 $ 323,269 Income (loss) from continuing operations 34,695 252 (10,858 ) 24,089 Depreciation and amortization 375 46 2 423 Provision for doubtful accounts receivables 1,657 16 2 1,675 Stock-based compensation 933 — 1,888 2,821 Impairment of assets — — — — Provision for (benefit from) income taxes 8,246 131 (855 ) 7,522 Total assets for the business segmen ts December 31, 2022 2021 (in thousands) GRE $ 191,839 $ 174,442 Genie Renewables 12,191 3,946 Corporate 18,592 16,668 Total assets of continuing operations 222,622 195,056 Assets of discontinued operations 54,993 34,409 Total assets $ 277,615 $ 229,465 Geographic Information Revenues from customers located outside of the United States, which are located primarily in Japan were as follows: United States Other Foreign Countries Total (in thousands) Year ended December 31, 2022 $ 315,539 $ — $ 315,539 Year ended December 31, 2021 319,339 3,930 323,269 Net long-lived assets and total assets of continuing operations, net held outside of the United States, which are located primarily in Israel, were as follows: United States Other Foreign Countries Total (in thousands) December 31, 2022 Long-lived assets of continuing operations, net $ 15,914 $ — $ 15,914 Total assets of continuing operations 221,003 1,619 222,622 December 31, 2021 Long-lived assets of continuing operations, net $ 15,238 $ 244 $ 15,482 Total assets of continuing operations 194,791 265 195,056 Long-lived assets consist of property and equipment, net, right-of-use assets, i ntangibl

Description of Business and Summary of Significant Accounting Policies
Description of Business	Description of Business Genie Energy Ltd. (“Genie”), a Delaware corporation, was incorporated in January 2011. Genie owns 99.5% of Genie Energy International Corporation (“GEIC”), which owns 100% of Genie Retail Energy (“GRE”), and 95.5% of Genie Renewables. In the third quarter of 2022, the company ceased to operate a former segment, GRE International. GRE, owns and operates retail energy providers (“REPs”), including IDT Energy, Inc. (“IDT Energy”), Residents Energy, LLC (“Residents Energy”), Town Square Energy, LLC and Town Square Energy East, LLC (collectivity, “TSE”), Southern Federal Power LLC ("Southern Power") and Mirabito Natural Gas (“Mirabito”). GRE's REPs' businesses resell electricity and natural gas to residential and small business customers primarily in the Eastern and Midwestern United States and Texas. Genie Renewables holds Genie Solar Energy ("Genie Solar"), an integrated solar energy company and a 92.8% interest in CityCom Solar, a marketer of community solar energy solution, Diversegy LLC ("Diversegy"), a broker for commercial customers, and GRE's 60.0% interest in Prism Solar Technology, Inc. ("Prism"), a solar solutions company that is engaged in the manufacturing of solar panels, solar installation design and solar energy project management. Discontinued operations in Finland and Sweden Previously, the Company had a third segment, Genie Retail Energy International, which supplied electricity to residential and small business customers in Scandinavia. However, The Company determined that the discontinued operations in Finland and Sweden represented a strategic shift that will have a major effect on the Company's operations and financial statements. 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. The results of operations and related cash flows are presented as discontinued operations for all periods presented. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 and 2021. Lumo Finland and Lumo Sweden will continue to liquidate their remaining receivables and settle any remaining liabilities. Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a separate segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Discontinued Operations in United Kingdom In third quarter of 2021, the natural gas and energy market in the United Kingdom deteriorated which prompted the Company to start the process of orderly withdrawal from the United Kingdom market. In October 2021, as part of the orderly exit process from the United Kingdom market, Orbit and Shell U.K. Limited ("Shell") agreed to terminate the exclusive supply contract between them. As part of the termination agreement, Orbit was required to unwind all physical forward hedges with Shell which resulted in net cash proceeds after settlement of all related liabilities with Shell. 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 The Company determined that the discontinued operations in the United Kingdom represented a strategic shift that will have a major effect on the Company's operations and financial statements. Since the appointment of the 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. The results of operations and related cash flows are presented as discontinued operations for all periods presented. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 and 2021 Energy Price Volatility in Japan and Texas In January 2021, weather volatility and the lack of adequate gas reserves significantly increased the price of energy at Japan Electric Power Exchange ("JEPX") for an extended period of time. The spike in demand associated with this situation, exposed Genie Japan to unexpected cost increases. Genie Japan incurred approximately $2.5 million in additional costs related to the price increases, which were included in the cost of revenue in the first quarter of 2021. In February of 2021, the State of Texas experienced unprecedented cold weather and snow, which was named Winter Storm Uri. With the grid overtaxed due to demand and weather-related reduced supply and rolling blackouts being enforced, by order of the Electricity Reliability Council of Texas ("ERCOT"), real-time commodity prices during the crisis escalated significantly. Although GRE's commitment for their customers in Texas was hedged for foreseen winter weather conditions, the market conditions exposed the Company to significant unexpected cost increases. In the year ended December 31, 2021, GRE recognized approximately $13.0 million in additional costs related to the situation, which were included in the cost of revenue in the consolidated statements of operation. In June 2021, the legislature of the State of Texas passed House Bill (“HB ”) which includes certain provisions for financing certain costs associated with electric markets caused by Winter Storm Uri. Pursuant to HB , categories of charges associated with Winter Storm Uri are to be securitized and the proceeds of the securitization will be provided to the load serving entities who originally incurred the charges. Under HB , the Company is entitled to recover a portion of the costs incurred from the effect of Winter Storm Uri with a calculated range of $ million to $ million. In the second quarter of , the Company recorded a reduction in cost of revenues of $ million. In September 2021, the Public Utility Commission of Texas ("PUC") approved the Debt Obligation Order to grant ERCOT's application for a debt financing mechanism to pay for certain costs associated with Winter Storm Uri. Under the Debt Obligation Order, the amount that the Company is entitled to recover increased to approximately $3.4 million. In the third quarter of 2021, the Company recorded an additional reduction in the cost of revenues of $1.9 million for an aggregate amount of $3.4 million for the year ended December 31, 2021. In June 2022, the Company received a $ 3.5 million refund related to the cost of Winter Storm Uri. Seasonality and Weather 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 and/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. Approximately39.7 and 44.5% of GRE’s natural gas revenues for the relevant years were generated in the first quarters of 2022 and 2021, 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), approximately30.5 and 30.3% of GRE’s electricity revenues for the relevant years were generated in the third quarters of 2022 and 2021, 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.
Basis of Consolidation	Basis of Consolidation The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries and the variable interest entity in which the Company is the primary beneficiary (see Note 14). All significant intercompany accounts and transactions between the consolidated entities are eliminated.
Equity Method Investments	Equity Method Investments 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.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates affecting amounts reported or disclosed in the consolidated financial statements include revenues, marketable equity securities and other investments, accounts receivables, allowances for doubtful accounts receivable, net realizable value of inventories, valuation of intangible assets, depreciation and amortization periods for long-lived assets, valuation allowances recorded against deferred tax assets, the valuation of stock-based compensation, valuation of derivative instruments, valuation of debt instruments and loss contingencies. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the current circumstances. Actual results may differ from those estimates.
Revenue Recognition	Revenue Recognition Revenues from the Sale of Electricity and Natural Gas 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. Variable quantities in requirements contracts are considered to be options for additional goods and services because the customer has a current contractual right to choose the amount of additional distinct goods to purchase. GRE and Genie Japan (prior to its sale in May 2021) record 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, 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 year. The Company determined that certain sales commissions to acquire customers meet the requirements to be capitalized. For GRE, the Company applies a practical expedient to expense costs as incurred for sales commissions to acquire customers as the period would have been one year or less. Revenues from Sale of Solar Panels Revenues 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 sale of solar panels are included in other revenues in the consolidated statements of operations. Revenues from sales of solar panels are included under the Other Revenues in the consolidated statements of operations.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported in the consolidated balance sheet that equals the total of the same amounts reported in the consolidated statement of cash flows: December 31, 2022 2021 (in thousands) Cash and cash equivalents $ 98,571 $ 93,568 Restricted cash—short-term 6,007 6,657 Total cash, cash equivalents, and restricted cash $ 104,578 $ 100,225 Restricted cash—short-term includes amounts set aside in accordance with the Amended and Restated Preferred Supplier Agreement with BP Energy Company (“BP”) (see Note Note Included in the cash and cash equivalents as of is cash received from Lumo Sweden ( see Note 2 ) Included in the cash and cash equivalents as of December 31, 2021 is cash received from Orbit Energy (see Note 2
Marketable Equity Securities and Other Investment	Marketable Equity Securities and Other Investment Marketable equity securities that are traded in the public market are carried at fair value using the quoted price at the end of each reporting period. Changes in the fair value are recorded as unrealized gains or losses on investments in the consolidated statements of operations.
Trade Accounts Receivable, Net	Trade Accounts Receivable, Net Trade accounts receivable, net is reported in the balance sheet as gross outstanding amounts adjusted for doubtful accounts.
Inventories	Inventories Inventory consists of natural gas, renewable energy credits and solar panels. Natural Gas Natural gas inventory is stored at various third parties’ underground storage facilities and is stated at lower of cost or net realizable value. The Company’s natural gas inventory was valued at weighted average cost, which was based on the purchase price of the natural gas and the cost to transport, plus or minus injections or withdrawals. Renewable Energy Credits GRE must obtain a certain percentage or amount of its power supply from renewable energy sources in order to meet the requirements of renewable portfolio standards in the states in which it operates. This requirement may be met by obtaining renewable energy credits that provide evidence that electricity has been generated by a qualifying renewable facility or resource. GRE holds renewable energy credits for both sale and use, and treats the credits as a government incentive to encourage the construction of renewable power plants. Renewable energy credits are valued at the lower of cost and net realizable value. Gains and losses from the sale of renewable energy credits are recognized in cost of revenues when the credits are transferred to the buyer. Solar Panels Inventories related to solar panels are stated at the lower of cost or net realizable value. The cost is determine using the first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor, and indirect manufacturing costs. The Company regularly reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. The Company also regularly evaluates the quantities and values of inventories, in light of current market conditions and trends among other factors and records write-downs for any quantities in excess of demand or for any obsolescence. This evaluation considers the use of modules in the systems business, expected demand, anticipated sales prices, strategic raw material requirements, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, product merchantability, and other factors. Market conditions are subject to change, and actual consumption of our inventory could differ from forecasted demand. Inventories consisted of the following: December 31, 2022 2021 (in thousands) Natural gas $ 3,302 $ 1,891 Renewable credits 10,531 15,610 Solar panels 1,881 219 Total inventories $ 15,714 $ 17,720
Long-lived Assets	Long-lived Assets Property, plant and equipment - net is stated at historical cost less accumulated depreciation and any impairment. The Company provides for depreciation using a straight-line method over estimated useful life of the assets. Any leasehold improvements are amortized over the lesser of the lease term or the useful life. The cost of major additions and improvements are capitalized, while maintenance and repair costs that do not improve or extend the lives of the respective assets are charged to operations as incurred. The estimated useful life of property plant and equipment as follows: Years Machinery and equipment 2 - 9 Computer software and development 2 - 5 Computers and computer hardware 2 - 5 Office equipment and other 4 - 27 The fair value of patents and trademarks, non-compete agreements and customer relationships acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: patents and trademarks are amortized on a straight-line basis over a 10 to 20-year period; non-compete agreements are amortized on a straight-line basis 9-year term and licenses are amortized on a straight-line basis over a 10-year period. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests the recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss based on excess of carrying value over fair value of the assets. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material.
Acquisitions	Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to 1 year from the acquisition date. For each acquisition, the Company undertakes a detailed review to identify other intangibles assets and a valuation is performed for all such identified assets. The Company uses several market participant measures to determine estimated value. This approach includes consideration of similar recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible asset value that the Company acquired is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, non-compete agreements, trademarks, patents as well as licenses. If the actual results differ from the estimates, the amount recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expenses of finite-lived intangible assets.
Goodwill and Indefinite Lived Intangible Assets	Goodwill and Indefinite Lived Intangible Assets Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite-lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The Company has 2 reportable segments with 3 underlying reporting units: GRE, GRE International, and Genie Renewables, which is comprised of Prism and Diversegy. The fair value of each reporting unit is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Calculating the fair value of the reporting units requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company performs its annual goodwill impairment test as of October 1. In reviewing goodwill for impairment, the Company has the option, for any or all of its reporting units that carry goodwill - to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (i.e. greater than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If the Company elects to perform a qualitative assessment and determines that an impairment is more likely than not, the Company is then required to perform the quantitative impairment test, otherwise no further analysis is required. The Company also may elect not to perform the qualitative assessment and, instead, proceed directly to quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether the Company chooses to perform the qualitative assessment or proceeds directly to the quantitative impairment test. T he determination of the fair value of our reporting units is based on an income approach that utilizes discounted cash flows for each reporting 3 820, Fair Value Measurements and Disclosure
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and on the type of hedging relationship. Due to the volatility of electricity and natural gas prices, GRE enters into futures contracts, swaps and put and call options as hedges against unfavorable fluctuations in market prices of electricity and natural gas and to reduce exposure from price fluctuations. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the futures contracts, swaps and put and call options are recorded at fair value as current and noncurrent assets or liabilities and any changes in fair value are recorded in “Cost of revenues” in the consolidated statements of operations. In addition to the above, GRE utilizes forward physical delivery contracts for a portion of their purchases of electricity and natural gas, which are defined as commodity derivative contracts. Using the exemption available for qualifying contracts, GRE applies the normal purchase and normal sale accounting treatment to its forward physical delivery contracts, thereby these contracts are not adjusted to fair value. GRE also applies the normal purchase and normal sale accounting treatment to forward contracts for the physical delivery of electricity in nodal energy markets that result in locational marginal pricing charges or credits, since this does not constitute a net settlement, even when legal title to the electricity is conveyed to the ISO during transmission. Accordingly, GRE recognizes revenue from customer sales, and the related cost of revenues, at the contracted price, as electricity and natural gas is delivered to retail customers.
Shipping and Handling Fees and Costs	Shipping and Handling Fees and Costs Amounts billed to customers for shipping and handling are included in revenues. The related minimal amount of shipping and freight charges incurred by the Company are included in cost of goods sold. Distribution and handling costs of $0.1 million were recorded in selling, general and administrative expense for each of the years ended December 31, 2022 and 2021, respectively.
Foreign Currency	Foreign Currency Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the consolidated statements of operations.
Advertising Expense	Advertising Expense Cost of advertising for customer acquisitions is charged to selling, general and administrative expenses in the period in which it is incurred. In each of the years ended December 31, 2022 and 2021, advertising expenses included in selling, general and administrative expenses was $7.0 million.
Income Taxes	Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense.
Contingencies	Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock issued and outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended December 31, 2022 2021 (in thousands) Basic weighted-average number of shares $ 25,629 $ 25,879 Effect of dilutive securities Shares underlying stock options and warrants 561 390 Non-vested restricted Class B common stock 176 47 Diluted weighted-average number of shares $ 26,366 $ 26,316 The following shares were excluded from the diluted earnings per share computations: Year ended December 31, (in thousands) 2022 2021 Shares underlying stock options — 126 Non-vested deferred stock units 210 580 Stock options were excluded from the diluted earnings per share computation in the year ended December 31, 2021 because the exercise prices of the stock options were greater than the average market prices of the Company's Class B common stock during the period. Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market condition for vesting of those deferred stock units was not met as of December 31, 2022 or 2021.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for grants of stock-based awards to its employees based on the estimated fair value on the grant date. Compensation cost for awards is recognized using the straight-line method over the requisite service period, which approximates the vesting period. Stock-based compensation is included in selling, general and administrative expense. Forfeitures of equity grants are recognized as incurred.
Vulnerability Due to Certain Concentrations	Vulnerability Due to Certain Concentrations Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash, certificates of deposit and trade accounts receivable. The Company holds cash, cash equivalents and restricted cash at several major financial institutions, much of which exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition. GRE’s REPs reduce their customer credit risk by participating in purchase of receivable, or POR, programs for a majority of their receivables. In addition to providing billing and collection services, certain utility companies purchase those REPs’ receivables and assume all credit risk without recourse to those REPs for those purchased receivables. GRE’s REPs’ primary credit risk with respect to those purchased receivables is therefore nonpayment by the utility companies. Certain of the utility companies represent significant portions of the Company’s consolidated revenues and consolidated gross trade accounts receivable balance during certain period, and such concentrations increase the Company’s risk associated with nonpayment by those utility companies. The following table summarizes the percentage of consolidated trade receivable by the customer that equaled or exceeded 10.0% of consolidated net trade receivables at December 31, 2022 and 2021 (no other single customer accounted for 10.0% or greater of our consolidated net trade receivable as of December 31, 2022 and 2021). December 31, 2022 2021 Customer A 10.2 % 12.5 % The following table summarizes the percentage of consolidated revenues from customers that equal or exceed revenues in the period (no other single customer accounted for more than 10.0 % of consolidated revenues in these periods): Year ended December 31, 2022 2021 Customer A 10.1 % na % Customer B na 11.7 na —less than 10.0% of consolidated revenue in the period
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts was as follows: (in thousands) Balance at beginning of period Additions charged (reversals credited) to expense Additions (deductions) Balance at end of period Year ended December 31, 2022 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 6,139 $ 2,515 $ (3,808 ) $ 4,846 Year ended December 31, 2021 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 4,636 $ 1,709 $ (206 ) $ 6,139
Fair Value Measurements	Fair Value Measurements Fair value of financial and non-financial assets and liabilities is defined as an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three-tier hierarchy for inputs used to measure fair value, which prioritizes the inputs to valuation techniques used to measure fair value, is as follows: Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 — unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset's or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.
Accounting Standards Updates	Accounting Standards Updates In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments The Company is currently evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows.
