Description of Business and Nature of Operations
Description of Business and Nature of Operations	Note 1– Description of Business and Nature of Operations EVgo Inc. (“EVgo”) owns and operates a public direct current (“DC”) fast charging network for electric vehicles (“EVs”) in the United States (“U.S.”). EVgo’s network of charging stations provides EV charging infrastructure to consumers and businesses. Its network is capable of charging all EV models and charging standards currently available in the U.S. EVgo partners with automotive original equipment manufacturers (“OEMs”), fleet and rideshare operators, retail hosts such as grocery stores, shopping centers, gas stations, parking lot operators, governments and other organizations and property owners in order to locate and deploy its EV charging infrastructure. EVgo Services LLC (“EVgo Services”) was formed in October 2010 as NRG EV Services, LLC, a Delaware limited liability company and wholly owned subsidiary of NRG Energy, Inc., an integrated power company based in Houston, Texas (“NRG”). On June 17, 2016, NRG sold a majority interest in EVgo Services to Vision Ridge Partners. On January 16, 2020 (the “Holdco Merger Date”), EVgo Holdco, LLC (“EVgo Holdco”), a Delaware limited liability company and a subsidiary of LS Power Equity Partners IV, L.P. (“LS Power”), completed an acquisition of EVgo Services, pursuant to the merger agreement (the “Holdco Merger Agreement”) among EVgo Services, its investors and EVgo Holdco, whereby EVgo Services became a wholly-owned subsidiary of EVgo Holdco, resulting in a change in control of EVgo Services (the “Holdco Merger”). EVgo Holdco had no operations prior to the Holdco Merger. The Company (as defined below) elected push-down accounting and all of the Company’s assets and liabilities related to LS Power were remeasured at fair value on the Holdco Merger Date. LS Power was considered to be the accounting acquirer and formed EVgo Holdings, LLC (“EVgo Holdings”) and EVgo Holdco as part of the transaction. EVgo Inc. (the “Company,” or “EVgo”) was incorporated in Delaware on August 4, 2020 under the name Climate Change Crisis Real Impact I Acquisition Corporation (“CRIS”). The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Initial Business Combination”). On October 2, 2020, the Company completed its initial public offering (the “Initial Public Offering”). Simultaneously with the closing of the Initial Public Offering, the Company completed the sale of 6,600,000 warrants (the “Private Placement Warrants”) at $1.00 in a private placement to Climate Change Crisis Real Impact I Acquisition Holdings, LLC (the “Sponsor”), generating gross proceeds of $6,600,000. On July 1, 2021 (the “CRIS Close Date”), the Company consummated the business combination (the “CRIS Business Combination”) with CRIS, CRIS Thunder Merger LLC (“Thunder Sub”), EVgo Holdings, EVgo Holdco and EVgo OpCo, LLC (“EVgo OpCo” and together with EVgo Holdings and EVgo Holdco, the “EVgo Parties”) pursuant to the business combination agreement dated January 21, 2021 (the “Business Combination Agreement”). Following the CRIS Close Date, the combined company is organized in an “Up-C” structure in which the business of EVgo Holdco and its subsidiaries are held by EVgo OpCo and continue to operate through the subsidiaries of EVgo Holdco and in which the Company’s only direct assets consist of equity interests in Thunder Sub, which, in turn, holds only common units in EVgo OpCo (“EVgo OpCo Units”). As of December 31, 2022, the Company, through Thunder Sub, owned 26.4% of the EVgo OpCo Units. As the sole managing member of EVgo OpCo, Thunder Sub operates and controls all of the business and affairs of EVgo OpCo and through EVgo OpCo and its subsidiaries, conducts its business. As a result, beginning on July 1, 2021 (the CRIS Close Date), the Company consolidated the financial results of EVgo OpCo and recorded a redeemable noncontrolling interest in its consolidated financial statements to reflect the EVgo OpCo Units that are owned by EVgo Holdings after the CRIS Close Date. As of December 31, 2022, EVgo Holdings held 195,800,000 EVgo OpCo Units, representing 73.6% of the total outstanding EVgo OpCo Units and an equal number of shares of the Company’s Class B common stock. Each EVgo OpCo Unit, together with one share of Class B common stock, is redeemable, subject to certain conditions, for either one share of Class A common stock, or, at EVgo OpCo’s election, the cash equivalent to the market value of one share of Class A common stock, pursuant to the Amended and Restated LLC Agreement of EVgo OpCo dated July 1, 2021 (the “EVgo OpCo A&R LLC Agreement”). Geopolitical and Macroeconomic Environment During the last several years, the global economy has experienced disruption and sustained volatility due to a number of factors. In particular, the global outbreak of COVID-19 resulted in significant volatility in the global and domestic economies, changes in consumer and business behavior, market downturns and restrictions on business and individual activities, resulting in overall reduced economic activity. More recently, Russia’s military invasion of Ukraine and the subsequent sanctions imposed on Russia, Belarus, the so-called Donetsk People’s Republic and the so-called Luhansk People’s Republic have led to and will likely continue to lead to, geopolitical instability, market uncertainty and supply disruptions. Finally, rising inflation has increased operating costs for many businesses and, together with slowing economic growth and fear of a recession, has led governments to change monetary policy in response. The current economic environment remains uncertain and the extent to which EVgo’s operating and financial results for future periods will be impacted by the ongoing impacts of the COVID-19 pandemic, the ongoing conflict in Ukraine, increasing inflation, supply-chain disruptions, government efforts to reduce inflation and any recession will largely depend on future developments, which are highly uncertain and cannot be reasonably estimated at this time.

Summary of Significant Accounting Policies	Dec. 31, 2022
Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Basis of Presentation and Consolidation The CRIS Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“GAAP”), primarily due to the fact that EVgo Holdings continues to control the Company through its ownership of the Company’s Class B common stock. As described in Note 1, EVgo Services was acquired by EVgo Holdco on the Holdco Merger Date and EVgo Holdco was partially acquired by EVgo through EVgo’s acquisition of EVgo OpCo Units, on the CRIS Close Date. The accompanying consolidated financial statements are presented in accordance with GAAP and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). References to GAAP issued by the Financial Accounting Standards Board (“FASB”) in these notes to the consolidated financial statements are to the FASB Accounting Standards Codification (“ASC”). The consolidated financial statements include the accounts of the Company and its subsidiaries and all intercompany transactions have been eliminated in consolidation. GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude and timing, certain subsequent events may be required to be reflected in the consolidated financial statements at the balance sheet date and/or required to be disclosed in the notes to the consolidated financial statements. The Company has evaluated subsequent events accordingly. Use of Estimates The consolidated financial statements have been prepared in accordance with GAAP. The preparation of EVgo’s consolidated financial statements requires the Company to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses and related disclosures of contingent assets and liabilities. Significant estimates made by management include, but are not limited to, variable consideration estimates for revenue, depreciable lives of property and equipment and intangible assets, costs associated with asset retirement obligations, the fair value of share-based compensation, earnout liability, warrant liability and the fair value measurements of assets and liabilities allocated for acquired businesses. Management bases these estimates on its historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results experienced may vary materially and adversely from EVgo’s estimates. Revisions to estimates are recognized prospectively. Concentration of Business and Credit Risk The Company maintains its cash accounts in commercial banks. Cash balances held in a commercial bank are secured by the Federal Deposit Insurance Corporation up to $250,000. At times, a portion of deposit balances may be in excess of federal insurance limits. The Company has not experienced any losses on such accounts and believes it is not exposed to any significant credit risk on cash. The Company mitigates its risk with respect to cash by maintaining its deposits at high-quality financial institutions and monitoring the credit ratings of those institutions. The Company had one customer that comprised 19.7% of the Company’s total accounts receivable as of December 31, 2022. The Company had two customers that comprised 32.4% of the Company’s total accounts receivable as of December 31, 2021. For the year ended December 31, 2022, two customers represented 42.9% of total revenue. For the year ended December 31, 2021, one customer represented 10.5% of total revenue. For the years ended December 31, 2022 and 2021, EVgo had four and two vendors, respectively, that provided more than 10% of EVgo’s total charging equipment. For the years ended December 31, 2022 and 2021, the amount provided by these vendors were 88.8% and 37.3% , respectively. Reclassifications The Company has made certain reclassifications to prior period amounts to conform to current period presentation. Cash, Cash Equivalents and Restricted Cash Cash and restricted cash include cash held in cash depository accounts in major banks in the U.S. and are stated at cost. Cash equivalents are carried at fair value and are primarily invested in money market funds. Cash that is held by a financial institution and has restrictions on its availability to the Company is classified as restricted cash. The Company had unused letters of credit, which were collateralized with cash classified as restricted cash on the Company's consolidated balance sheets, of $0.7 million as of December 31, 2022 and 2021, associated with the construction of its charging stations and in connection with one of its operating leases. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are amounts due from customers under normal trade terms. Payment terms for accounts receivable related to capital-build agreements are specified in the individual agreements and vary depending on the counterparty. Management reviews accounts receivable on a recurring basis to determine if any accounts receivable will potentially be uncollectible. The Company reserves for any accounts receivable balances that are determined to be uncollectible in the allowance for doubtful accounts. After all attempts to collect an account receivable have failed, the account receivable is written-off against the allowance for doubtful accounts. Other accounts receivable of $1.3 million and a de minimis amount were included in accounts receivable, net, on the consolidated balance sheets as of December 31, 2022 and 2021, respectively. Deferred Offering Costs Deferred offering costs, consisting primarily of legal, accounting and filing fees relating to public offerings, are capitalized. The deferred offering costs will be offset against public offering proceeds upon the effectiveness of an offering. In the event that an offering is abandoned or terminated, deferred offering costs will be expensed. As of December 31, 2022 and 2021, the Company had capitalized $1.0 million and $0.2 million, respectively, of deferred offering costs in other current assets on the consolidated balance sheets. Cloud Implementation Costs The Company capitalizes certain implementation costs incurred related to cloud computing arrangements that are service contracts. Such costs are amortized on a straight-line basis over the term of the associated hosting arrangement plus any reasonably certain renewal period. Any capitalized amounts related to such arrangements are recorded within prepaid expense and other current assets and within non-current assets on the consolidated balance sheets. Property, Equipment and Software Property and equipment includes land, charging stations and other technical installations, construction in process, charging station and related equipment and a building, which are stated at cost or at fair value as of the date of acquisition less accumulated depreciation and amortization. Land is not depreciated. Depreciation for property, equipment and software is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful life of the building is forty years and the estimated useful lives of the remaining assets are approximately three The Company has adopted the provisions of ASC Topic 350-40, Internal-Use Software, Goodwill and Other Intangible Assets Goodwill represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. The Company’s goodwill and intangible assets are the result of the Holdco Merger and as part of the acquisition of PlugShare LLC (f/k/a Recargo, Inc.) (see Note 3). EVgo completes an impairment test of goodwill at least annually or more frequently if facts or circumstances indicate that goodwill might be impaired. EVgo’s annual impairment test date is October 1st. Goodwill is tested for impairment at the reporting unit level. EVgo first performs a qualitative assessment of EVgo’s single reporting unit. Factors considered in the qualitative assessment include general macroeconomic conditions, industry and market conditions, cost factors, overall financial performance of EVgo’s reporting unit, events or changes affecting the composition or carrying amount of the net assets of EVgo’s reporting unit, any sustained decrease in EVgo’s share price and other relevant entity-specific events. If EVgo elects to bypass the qualitative assessment or if EVgo determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, a quantitative test would be required. EVgo then performs the goodwill impairment test for each reporting unit by comparing the reporting unit’s carrying amount, including goodwill, to its fair value, which is measured based upon, among other factors, a discounted cash flow analysis, as well as market multiples for comparable companies. Estimates critical to EVgo’s evaluation of goodwill for impairment include forecasts for revenue, EBITDA growth and long-term growth rates, as well as the discount rates. If the carrying amount of the reporting unit is greater than its fair value, goodwill is considered impaired. EVgo did not recognize any impairment losses for any periods presented. It is possible in future periods that further declines in market conditions, customer demand or other potential changes in operations may increase the risk that these assets may become impaired. Finite-lived intangible assets are amortized over their useful lives and recorded as either cost of sales or operating expenses depending on the nature of the intangible asset. Costs incurred to renew or extend the term of recognized intangible assets are expensed as incurred. During the fourth quarter of 2022, the Company reviewed its goodwill and other intangible assets for indicators of impairment and performed its annual goodwill impairment analysis as part of this review. The Company did not note any indicators of impairment with respect to its goodwill or other intangible assets as of December 31, 2022 and no impairment charge was required. Estimated useful lives of the Company’s intangible assets are presented below: Site Host relationships 12 years Customer relationships 4-5 years Developed technology 10-15 years User base 4 years Trade name 15-20 years Long-Lived Asset Impairment The Company reviews its long-lived assets, including property and equipment, right-of-use assets and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If the Company identifies events or changes in circumstances that could impact recoverability, the Company compares the carrying value of the assets or asset groups with their estimated future undiscounted cash flows. If it is determined that an impairment has occurred, the loss would be recognized during that period. The impairment loss would be calculated as the difference between the asset or asset group carrying values and the present value of estimated net cash flows or comparable market values, giving consideration to recent operating performance and pricing trends. EVgo did not recognize any impairment losses for any periods presented. It is possible in future periods that further declines in market conditions, customer demand or other potential changes in operations may increase the risk that these assets may become impaired. During the fourth quarter of 2022, the Company reviewed its long-lived assets for indicators of impairment, did not note any indicators of impairment and no impairment charge was required. Lease Accounting The Company accounts for leases under ASC Topic 842, Leases The Company’s lease agreements primarily require lease payments based on a minimum annual rental amount. In addition to minimum lease payments, the Company’s lease agreements may contain variable lease payments based on revenue-sharing or inflation adjustments. The Company has elected the practical expedient to not separate non-lease components from lease components in the measurement of liabilities for all asset classes. Lease liabilities are recognized at the present value of the fixed lease payments using an implicit rate and, if not available, an incremental borrowing rate based on estimated collateralized borrowings available to the Company. The Company incurs initial direct costs and receives landlord incentives that increase or decrease the calculated right-of-use asset, respectively. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company expenses variable lease payments as incurred. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company has not entered into any finance leases. As a lessor, the Company has entered into agreements to lease charging equipment, charging stations and other technical installations or sublease properties leased from Site Hosts to third parties. The Company, at the inception of a lease contract, determines if it is an operating, sales-type or direct financing lease. The Company has not elected the practical expedient to not separate non-lease components from lease components in the measurement of liabilities for all asset classes. The leases generally provide for fixed monthly payments and sometimes include provisions for contingent variable rent based on the number of charging sessions and minutes used, which are recognized when earned. Fixed payments received under lease agreements for operating leases are recognized on a straight-line basis over the lease term and are reported in revenue in the consolidated statements of operations. Deferred Revenue Deferred revenue consists of billings on contracts where performance has commenced and payments have been received in advance of revenue recognition. Deferred revenue is recognized into revenue as the related revenue recognition criteria are met. Customer Deposits Customer deposits include prepayments that are refundable. Once deposits are no longer refundable, the Company reclassifies the amounts related to those contracts to deferred revenue. Customer deposits are also comprised of funds that have been received to offset future expenses of the Company for certain marketing expenses reimbursed by customers. Capital-Build Liability and Expense Reimbursements The Company receives grant funding in the form of cash from governmental and non-governmental entities to construct and operate EV chargers. As there is no authoritative guidance under GAAP regarding accounting for government assistance to for-profit business entities, the grants directly or indirectly provided by the government are accounted for by analogy to International Accounting Standard (“IAS”) 20, Accounting for Government Grants and Disclosure of Government Assistance Revenue from Contracts with Customers The charging stations purchased and installed under these programs or agreements are recorded in property and equipment. At the time the expenditures for the charging stations have been incurred, the funding associated with the charging station capital expenditure is deferred as a capital-build liability and amortized against depreciation expense over the remaining useful life of the related assets. The Company retains ownership of these charging stations. Reimbursement under the agreements for operating and maintenance expenses is recognized as an offset to cost of revenue in the consolidated statements of operations in the period in which EVgo recognizes the related costs of operation and maintenance of the chargers. Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging Earnout Liability In accordance with ASC 815, Earnout Shares (as defined in Note 3) were initially recorded as a derivative liability at fair value as of the CRIS Close Date, since they are not indexed to the Company’s Class A common stock. They are subsequently remeasured at each reporting date through the change in fair value of earnout liability in the consolidated statements of operations. The estimated fair value of the contingent earnout liability is determined using a Monte Carlo simulation using a distribution of potential outcomes on a monthly basis over the Earnout Period (as defined in Note 17), prioritizing the most reliable information available. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including the current common stock price, expected volatility, risk-free rate, expected term and dividend rate. Until its settlement, the contingent earnout liability is categorized as a Level 3 (defined below) fair value measurement because the Company utilizes projections during the Earnout Period that include unobservable inputs. Contingent earnouts involve certain assumptions requiring significant judgment and actual results can differ from assumed and estimated amounts. Asset Retirement Obligations Asset retirement obligations represent the estimated present value of the amount the Company will incur for dismantling and restoring sites (locations owned by unrelated parties where the Company’s chargers are placed) at the end of their agreements, in accordance with their contractual terms. Upon initial recognition of the Company’s asset retirement obligation liability, property and equipment is increased by an amount offsetting the liability and depreciated over its useful life and the obligation is accreted to its estimated future value at the date of retirement. Subsequent to establishing an asset retirement obligation, downward revisions in the liability due to a change in the expected timing or amount of cash flows are recorded as corresponding decreases to the asset retirement costs; however, if the amount of the decrease exceeds the carrying value of the related asset retirement cost and related asset, such excess credits are adjusted through a reduction of accretion expense. Asset retirement obligations require the use of estimates to determine third-party costs for dismantling and restoring the sites. Discount rates are also included to present value these costs, which are then accreted to the date the Company expects to remove the corresponding asset. Discount rates are based on the Company’s estimated credit adjusted risk-free rate. The Company reviews its estimates of removal costs on an ongoing basis and makes changes to the asset retirement obligations as necessary. Warrant Liability The Company accounts for its issued and outstanding warrants (as described in Note 16) in accordance with the guidance contained in ASC 815, under which the warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the warrants as liabilities at their fair value and adjusts the warrants to fair value at the end of each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised or redeemed by the Company and any change in fair value is recognized in the statements of operations. The fair value of the redeemable warrants (the “Public Warrants”), originally sold as part of the units issued in the Company’s Initial Public Offering, has been estimated using the closing price of the Public Warrants as of December 31, 2022 and 2021. The Private Placement Warrants were initially valued using a Monte Carlo simulation model, which was a level 3 (defined below) fair value measurement. Commencing June 30, 2022, the fair value of the Private Placement Warrants was measured by reference to the trading price of the Public Warrants, which is considered to be a Level 2 (defined below) fair value measurement. Fair Value Measurement The Company determines fair value in accordance with ASC 820, Fair Value Measurement Details on the methods and assumptions used to determine the fair values are as follows: ● Fair value measurements based on Level 1 inputs: Measurements that are most observable and are based on quoted prices of identical instruments obtained from the principal markets in which they are traded. Closing prices are both readily available and representative of fair value. Market transactions occur with sufficient frequency and volume to assure liquidity. ● Fair value measurements based on Level 2 inputs (“Level 2”): Measurements derived indirectly from observable inputs or from quoted prices from markets that are less liquid are considered Level 2. ● Fair value measurements based on Level 3 inputs: Measurements that are least observable are estimated from significant unobservable inputs determined from sources with little or no market activity for comparable contracts or for positions with longer durations. The carrying values of certain accounts such as accounts receivable, accounts payable and accrued expenses are deemed to approximate their fair values due to their short-term nature. The fair values of the Company’s money market funds are based on quoted prices in active markets for identical assets. Revenue Recognition The Company’s sources of revenue are from retail, commercial and OEM charging contracts, regulatory credits, OEM network contracts, eXtend, and ancillary services. Its primary source of revenue is charging contracts with customers. A significant portion of the Company’s charging contracts have upfront payment terms or monthly payment terms. Payments for walk-up retail charging usage are collected at the point of service, except for monthly member fees and member usage fees which are billed monthly in arrears. Payments for development and project management revenue occur either on an installment basis or are received upon completion of milestones. Payment terms vary on a contract-by-contract basis, although terms generally include a requirement of payment within 30 to 60 days. Revenues for regulatory credits such as LCFS credit sales are recognized upon delivery. The Company recognizes revenue pursuant to ASC 606, using a five-step model: (a) identification of the contract, or contracts, with a customer; (b) identification of the performance obligations in the contract; (c) determination of the transaction price; (d) allocation of the transaction price to the performance obligations in the contract; and (e) recognition of revenue when, or as, it satisfies a performance obligation. The transaction price for each contract is determined based on the amount the Company expects to be entitled to receive in exchange for transferring the promised products or services to the customer. Collectability of revenue is reasonably assured based on historical evidence of collectability of fees the Company charges its customers. The transaction price in the contract is allocated to each distinct performance obligation in an amount that represents the relative amount of consideration expected to be received in exchange for satisfying each performance obligation. Revenue is recognized when performance obligations are satisfied. At contract inception, the Company determines whether it satisfies the performance obligation over time or at a point in time. Revenue is recorded based on the transaction price excluding amounts collected on behalf of third parties such as sales taxes, which are collected on behalf of and remitted to governmental authorities. The Company may also incur fulfillment costs that are reimbursed by its customers as pass-through costs that may or may not be subject to a mark-up. Reimbursement for fulfillment costs is included in the transaction price and is recognized on a gross basis. The Company recognizes estimated losses on contracts immediately upon identification of the loss. Some of the Company’s contracts with customers only contain a single performance obligation. When agreements involve multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct. The Company applies significant judgment in identifying and accounting for each performance obligation, as a result of evaluating terms and conditions in contracts. The transaction price is allocated to each performance obligation based on the relative standalone selling price (“SSP”). The Company determines the SSP based on observable SSP when it is available, as well as other factors, including the price charged to its customers, its discounting practices and its overall pricing objectives, while maximizing observable inputs. EVgo’s contracts may provide its customers with the option to renew the agreement. Generally, this option is not considered to provide a material right that should be accounted for as a separate performance obligation because the customer would not receive a discount if it decided to renew and the option to renew is generally cancellable by either party subject to the notice of non-renewal requirements specified in the contract. If a material right is identified, the Company would account for these accordingly as separate performance obligations. EVgo’s contracts may also provide its customers with the option to purchase additional future services. Generally, this option is not considered to provide the customer with a material right that should be accounted for as a separate performance obligation since the cost of the additional future services are generally at market rates for such services and the Company is not automatically obligated to stand ready to deliver these additional goods or services because the customer may reject EVgo’s proposal. Areas of Judgment and Estimates The Company exercises judgment in determining which promises in a contract constitute performance obligations rather than set-up activities. The Company determines which activities under a contract transfer a good or service to a customer rather than activities that are required to fulfill a contract but do not transfer control of a good or a service to the customer. Determining whether obligations in a contract are considered distinct performance obligations that should be accounted for separately or as a single performance obligation requires significant judgment. In reaching its conclusion, the Company assesses the nature of each individual service offering and how the services are provided in the context of the contract, including whether the services are significantly integrated which may require judgment based on the facts and circumstances of the contract. Determining the relative SSP for contracts that contain multiple performance obligations requires significant judgment to appropriately determine the suitable method for estimating the SSP. The Company determines SSP using observable pricing when available, which takes into consideration market conditions and customer specific factors. When observable pricing is not available, the Company determines SSP using estimation techniques, but maximizes the use of observable inputs in these estimation techniques. The Company’s customer contracts may include variable consideration such as that due to the unknown number of users that will receive charging credits or an unknown number of sites that will receive maintenance services. The Company estimates variable consideration under the expected value method or the most likely amount method. If charging station installations are not completed by specified dates, the Company may be subject to installation penalties. The Company may also be subject to other penalties identified in the customer agreements upon failure to maintain specified network uptimes and for other contractual service requirements. Variable consideration for installation, service, and other penalties is estimated using the most likely amount method. Practical Expedients and Exemptions The Company elected the practical expedient to not adjust the consideration in a contract for the effects of a significant financing component if the Company expects, at contract inception, that the period between receipt of payment and the transfer of promised goods or services will be less than one year. In some cases, the Company receives payment in advance of the transfer of promised goods or services. For contracts in which revenue is recognized over time and the entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, the Company recognizes revenue at the amount to which it has the right to invoice. The Company does not disclose the transaction price allocated to remaining performance obligations for (i) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice and (ii) contracts with variable consideration allocated entirely to a single performance obligation. The Company’s remaining performance obligations under these contracts include providing charging services, branding services and maintenance services which will generally be recognized over the contract term. An asset is recognized for the incremental costs of obtaining a contract with a customer if the benefit of those costs is expected to be longer than one year. A practical expedient to expense costs as incurred for costs to obtain a contract with a customer is applied when the amortization period would have been one year or less. Contract costs are evaluated for impairment in accordance with ASC 310, Receivables Contract Balances Differences in the timing of revenue recognition, billings and cash collections result in contract assets and contract liabilities. Contract Assets Contract Liabilities EVgo’s contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period, when applicable. From time-to-time, the payment terms of contracts require the customer to make advance payments as well as interim payments as work progresses. These advance payments generally are not considered to contain a significant financing component. Sales Tax Collected from Customers As a part of the Company’s normal course of business, sales taxes are collected from customers in accordance with local regulations. Sales taxes collected are remitted, in a timely manner, to the appropriate governmental tax authority on behalf of the customer. The Company’s policy is to present revenue and costs net of sales taxes. Cost of Sales and General and Administrative Expenses Cost of sales consists primarily of energy usage fees, depreciation, net of capital-build amortization expenses, site operating and maintenance expenses, customer service and network charges, warranty and repair services, site costs and related expense associated with charging equipment. General and administrative expenses primarily consist of payroll and related personnel expenses, IT and office services, office rent expense and professional services. Advertising Costs Advertising costs are generally expensed as incurred and totaled $2.0 million and $1.6 million for the years ended December 31, 2022 and 2021, respectively. Research and Development Costs Research and development costs are expensed as incurred and totaled $4.8 million and $2.0 million for the years ended December 31, 2022 and 2021, respectively. 401(k) Plan The Company has a 401(k) plan that qualifies under Section 401(k) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). The 401(k) plan provides discretionary employer matching contributions to eligible employees up to 2% of an employee’s eligible gross pay up to IRS annual limits. Employer contributions to the 401(k) plan for the year ended December 31, 2022 were $0.7 million and de minimis for the year ended December 31, 2021. Share-Based Compensation The Company recognizes compensation expense for all awards granted based on the grant date fair value. Compensation expense for awards that vest in increments is recognized based on an accelerated attribution method. In accordance with ASC Topic 718, Compensation – Stock Compensation Income Taxes EVgo and Thunder Sub are each classified as a corporation for federal income tax purposes and are subject to U.S. federal and state income taxes. EVgo and Thunder Sub report U.S. federal income taxes

Business Combinations	Note 3 – Business Combinations Climate Change Crisis Real Impact I Acquisition Corporation CRIS was formed on August 4, 2020 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase reorganization or similar business combination with one or more climate focused businesses. On January 21, 2021, EVgo Parties and CRIS entered into the Business Combination Agreement for EVgo Holdco and its subsidiaries to become partially owned by a publicly listed company, with the combined company organized in an “Up-C” structure. Completion of the proposed transaction was subject to customary closing conditions, including the approval of the stockholders of CRIS. On the CRIS Close Date, the Company consummated the CRIS Business Combination. CRIS was the legal acquirer of a certain portion of EVgo OpCo and its subsidiaries and the consideration received by EVgo Holdings in connection with the CRIS Business Combination consisted of shares of Class B common stock and EVgo OpCo Units and the rights under the Tax Receivable Agreement (see Note 19). The CRIS Business Combination was accounted for in accordance with ASC 805, Business Combinations In connection with the execution of the Business Combination Agreement, on January 21, 2021, CRIS entered into separate subscription agreements with certain investors (“PIPE Investors”), whereby it issued 40,000,000 shares of Class A common stock at $10.00 per share (“PIPE shares”) for an aggregate purchase price of $400.0 million in a private placement (the “PIPE”). EVgo Services’ note payable, related party (including accrued interest), was $59.6 million on July 1, 2021, which was converted into equity. Upon completion of the CRIS Business Combination, the voting interests, as of July 1, 2021, in the Company were as follows: (shares in thousands) Shares % Stockholder EVgo Holdings (LS Power) 1 195,800 74% CRIS’s Class A stockholders 22,987 9% PIPE Investors 40,000 15% CRIS’s converted founder shares 5,750 2% Closing Class A and B shares 264,537 100% 1 In addition to the shares, CRIS issued Private Placement Warrants and Public Warrants to purchase shares of Class A common stock in connection with its Initial Public Offering, which remained outstanding following the closing of the CRIS Business Combination. As of December 31, 2022, an aggregate of 18,097,120 warrants to acquire shares of Class A common stock were outstanding, comprised of 3,148,569 Private Placement Warrants and 14,948,551 Public Warrants. Each warrant is exercisable for one share of Class A common stock at a price of $11.50 per share. The fair value of these warrants as of July 1, 2021 was $79.6 million. The table below summarizes the net cash received by EVgo upon the closing of the CRIS Business Combination, net of transactions costs and redemptions: (in thousands) Gross proceeds from PIPE $ 400,000 Gross proceeds from CRIS 230,180 Less transaction costs (58,147) Less redemptions (132) $ 571,901 In connection with the CRIS Business Combination, certain initial stockholders of CRIS entered into an agreement with the Sponsor (the “Sponsor Agreement”) that provides for certain transfer restrictions and forfeiture provisions, among other things. Pursuant to the Sponsor Agreement, the initial stockholders party thereto are required to forfeit up to 1,437,500 shares (the “Earnout Shares”) received upon conversion of shares of Class B common stock of CRIS held by such stockholders at closing of the CRIS Business Combination if certain events do not occur. The estimated fair value of the Earnout Shares issued and outstanding upon closing was $18.3 million and was accounted for as a derivative liability (see Note 17). In connection with the CRIS Business Combination, there were direct and incremental transaction costs incurred, consisting primarily of investment banking, legal, accounting and other professional fees, which were recorded to additional paid-in capital as a reduction of proceeds. The $58.1 million includes $8.1 million in deferred underwriting fees of CRIS that were incurred prior to close and paid out as part of the CRIS Business Combination. Other incremental costs of $3.6 million were also incurred and expensed by the Company during the year ended December 31, 2021, primarily related to advisory, legal, accounting fees and other professional services in conjunction with the CRIS Business Combination, which are included in general and administrative expenses in the consolidated statement of operations. There were no incremental costs related to the CRIS Business Combination incurred during the year ended December 31, 2022. PlugShare LLC On July 9, 2021 (the “PlugShare Acquisition Date”), the Company entered into a stock purchase agreement (the “PlugShare Agreement”) to acquire 100% of the outstanding common stock of PlugShare LLC (f/k/a Recargo, Inc.). Effective as of December 29, 2021, Recargo, Inc. a California corporation, converted into EVgo The Company accounted for the acquisition of PlugShare as a business combination under ASC 805. Pursuant to ASC 805, the purchase price is allocated to the identifiable assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. Any excess of the amount paid over the estimated fair values of the identifiable net assets acquired is allocated to goodwill. The total purchase price was $25.0 million, per the terms of the PlugShare Agreement, none of which were contingent upon future financial results. The table below summarizes the allocation of the fair value of the assets acquired and liabilities assumed by the Company on the PlugShare Acquisition Date, including resulting goodwill. Goodwill of $8.9 million was recorded as a result of the PlugShare acquisition and reflects assets not separately identifiable under ASC 805. Goodwill is expected to be amortizable for U.S. federal income tax purposes. The Company determined the fair values of the assets acquired and liabilities assumed with the assistance of a third-party valuation firm. Intangible assets recorded on the PlugShare Acquisition Date include user base, trade name and technology of $11.0 million, $1.1 million and $2.2 million, respectively. The fair values of the intangible assets were determined based on a discounted cash flow model using the with-or-without method for user base and the relief-from-royalty method for trade name and technology. Each of these methods is a form of the income approach. These methods incorporate various estimates and assumptions, such as projected revenue growth rates, profit margins and forecasted cash flows based on discount rates and terminal growth rates. The fair values of the property and equipment were determined using the cost approach. This approach involves adjusting the historical cost basis of the assets in the fixed asset register for inflation and then deducting for various forms of obsolescence. For the remaining assets and liabilities, the cost method was used to determine their respective fair values. The fair value of accounts receivable, consisting of customer receivables, approximated the carrying value, which was equal to the gross contractual amounts receivable because no portion of such contractual amounts was expected to be uncollectible. The following table summarizes the final fair values of the assets acquired and liabilities assumed at the PlugShare Acquisition Date: PlugShare Acquisition Date (in thousands) Fair Value Current assets Cash $ 1,943 Accounts receivable 605 Prepaid expenses and other current assets 76 Total current assets 2,624 Restricted cash 300 Property and equipment 678 Intangible assets 14,300 Other assets 70 Total assets 17,972 Current liabilities Accounts payable 84 Accrued expenses 769 Deferred revenue, current 543 Total current liabilities 1,396 Capital-build liability 480 Asset retirement obligations 32 Total liabilities 1,908 Net assets acquired 16,064 Consideration paid 25,005 Goodwill recognized $ 8,941 The following unaudited pro forma financial information presents consolidated revenue and net loss for the periods indicated as if the PlugShare acquisition had occurred on January 1, 2021: Year Ended December 31, (in thousands) 2021 Pro forma revenue $ 23,150 Pro forma net income (loss) $ (60,539) The above unaudited pro forma results have been calculated by combining the historical results of the Company and PlugShare, as if the acquisition had occurred as of the beginning of the earliest period presented in the Company’s consolidated financial statements and exclude the impact of acquisition-related expenses. The pro forma table above also includes estimates for additional depreciation, amortization and accretion related to the fair values of property and equipment, intangible assets, capital build liability and asset retirement obligations that were included as the basis of those assets acquired and liabilities assumed in the business acquisition. Pro forma net loss was adjusted to exclude acquisition-related costs incurred during the periods presented. No other material pro forma adjustments were deemed necessary. The pro forma financial information is not necessarily indicative of the results that would have been achieved had the transactions occurred on the date indicated or that may be achieved in the future. For the period from the PlugShare Acquisition Date of July 9, 2021 through December 31, 2021, revenue and net loss from PlugShare totaling $1.6 million and $5.2 million, respectively, are included in the consolidated statement of operations for the year ended December 31, 2021, which includes $0.6 million of acquisition-related expenses in general and administrative expenses.

Revenue Recognition
Revenue Recognition	Note 4 – Revenue Recognition Revenue Streams The Company’s revenue streams, respective performance obligations and methods of recognition are summarized below. All the Company’s revenues are sourced from the U.S. Charging Revenue, Retail. EVgo sells electricity directly to drivers who access EVgo’s publicly available networked chargers. Various pricing plans exist for customers and drivers have the choice to charge as members (with monthly fees and reduced per-minute or kilowatt-hour (“kWh”) pricing) through a subscription service or as non-members. Revenue for these sales is recognized at a point in time upon delivery of electricity and is charged to the customer based on electrical power delivered, minutes of charging, or on a fee basis. Monthly membership fees are charged to the customer and recognized on a monthly basis. Charging Revenue, Commercial. Commercial revenue is derived from contracts with high volume fleet customers, such as transportation network companies (“TNCs”) or delivery services, that can access EVgo’s charging infrastructure through EVgo’s public network. In addition to offering access to its public network, EVgo offers dedicated charging solutions to fleets. As part of this offering, EVgo typically builds, owns and operates charging infrastructure for the exclusive use of a dedicated customer and is currently offering flexible ownership models, such as its charging as a service (“ChaaS”) offering. Any lease components that are identified for dedicated fleet hubs are accounted for in accordance with ASC 842. Non-lease components and fulfillment costs are accounted for in accordance with ASC 606 and are recognized upon delivery of electricity and charged to the fleet customer based on electrical power delivered or minutes of charging and may be subject to a minimum usage requirement. Charging Revenue, OEM. The Company contracts with various automobile manufacturers (“OEMs”) to provide charging services to purchasers of their vehicles (“OEM Customers”) through charging credits or charging memberships, generally ranging up to five years in duration, and revenues are recognized as electricity is provided to the OEM Customers. At the end of the contract, the OEM Customer can convert the account to a monthly subscription service or a “pay as you go” account. Certain OEM contracts provide charging credits for OEM Customers and revenue is recognized at a point in time when OEM Customers use the credits for charging sessions. Other charging memberships provide OEM customers with a stand-ready obligation and revenue is recognized over time based on the membership period. Regulatory Credit Sales. As a charging station owner and operator, the Company earns revenue from the sale of regulatory credits such as LCFS credits in states where such programs are enacted currently, including the Fast Charging Infrastructure (“FCI”) program in California. These credits are generated through charging stations based on the volume of kWh sold. EVgo earns revenue through the sale of these credits to buyers obligated to purchase the credits to comply with the FCI program mandates. The Company’s performance obligation is to sell regulatory credits to certain of its customers. As such, revenue is recognized at the point of sale. The Company records the value of the credits generated from operations based on an incremental cost basis and determined this cost to be nominal. Network Revenue, OEM. Network revenue, OEM is related to contracts that have significant charger infrastructure build programs, which may represent set-up costs under ASC 606 for chargers that are owned by the Company. The transaction prices from these contracts are allocated to performance obligations including, but not limited to, marketing activities, branding services, memberships and reservations. Revenue from marketing activities is recognized at a point in time on a net basis as the marketing services are rendered. Memberships are stand-ready obligations and revenue is recognized over time. For reservations, revenue is recognized at a point in time once the performance obligation is satisfied. Branding is recognized over time as the customer receives the benefit. Prepaid charging credits that expire unused are recognized as breakage using the proportional method or, for programs where there is not enough information to determine the pattern of rights exercised by the customer, the remote method. eXtend Revenue. application support and related services. In 2022, EVgo announced an eXtend deal with the Pilot Company to deploy up to 2,000 fast charging stalls that the Pilot Company will own and EVgo will build, network, operate and maintain. For the eXtend offering, the Company generally has multiple performance obligations including, but not limited to, the sales of equipment, the provision of engineering, procurement, and construction services during the construction lifecycle, and the provision of operations and maintenance services once the charging network is operational. Revenue from sales of equipment is generally recognized at a point in time when the performance obligation is satisfied. The Company’s performance obligation under development contracts is to develop and deliver a completed site with installed charging hardware. The build-out fee can be structured as firm-fixed price or cost-plus arrangements and becomes payable as certain contract and/or construction milestones are achieved or as construction costs are incurred monthly. Development and project management revenue is recognized over time using the relevant input method, which is generally either time-based or cost-based. Under the time-based and cost-based methods, all costs incurred in the period that relate to a contract are charged to cost of sales and the related revenue is recognized based on the measured progress to completion. EVgo may provide latent defect warranties for equipment and installation labor services related to EVgo’s charger installation services. EVgo’s warranty obligations are generally not accounted for as separate performance obligations as warranties cannot be separately purchased and warranties do not provide a service in addition to the assurance that the charging stations will function as expected. The operations and maintenance fees generally commence once the charging stations become operational with recurring fees generally based upon a fixed or variable rate. For maintenance services that are invoiced monthly, the Company has elected to recognize revenue using the as-invoiced practical expedient. Ancillary Revenue. EVgo has a number of offerings that currently include customization of digital applications, charging data integration, micro-targeted advertising services, smart charging reservations, loyalty programs and access to chargers behind parking lot pay gates. EVgo also offers equipment procurement and operations services for customers who operate dedicated networks. For software-driven digital, equipment procurement and operations services, the Company recognizes revenue at a point in time or over time based on when the performance obligation is met. The Company provides research and consulting services to its PlugShare customers. These are generally short-term projects and the Company recognizes revenue at a point in time upon delivery of the results of the research and consulting services to the customer. The Company enters into short-term and long-term contracts with PlugShare customers to provide charging data integration services. The contract fees for the data integration services are generally structured as a fixed fee arrangements over a specified licensing period and revenue is generally recognized for the single performance obligation monthly, on a straight-line basis, over the licensing period. The Company generally enters into short-term cancelable insertion orders with its advertising customers for advertising campaigns that are served through the PlugShare software platform. Sponsorship advertising arrangements are generally priced under a cost per engagement structure, which is a set price per click or engagement. Advertising customer contracts may contain multiple performance obligations with each distinct service. The performance obligations are generally considered a series of distinct services as the performance obligations are satisfied over time and revenue is recognized in the period of delivery. The contract transaction price is comprised of variable consideration based on the stated rates applied against the number of units delivered inclusive of the bonus units subject to the maximums provided in the contract. The contractual rates and actual units delivered are used to determine the transaction price each period end. The transaction price is allocated to each performance obligation based on the SSP of each performance obligation. Advertising revenue is recognized ratably over the service period based on actual units delivered subject to the maximums under the contract.

Under many customer contracts, each unit of product represents a separate performance obligation and therefore future volumes are wholly unsatisfied and thus disclosure of the transaction price allocated to a wholly unsatisfied performance obligations is not required. Under these contracts, variability arises as both volume and pricing are not known until the product is delivered. As of December 31, 2022 and 2021, there was $8.7 million and $22.9 million, respectively, in variable consideration for wholly unsatisfied performance obligations, which is included in deferred revenue on the consolidated balance sheets.

Holders of Class B common stock are entitled to one vote for each share. Prior to the CRIS Business Combination, only holders of shares of Class B common stock of CRIS had the right to vote on the election of directors. Holders of Class A common stock and Class B common stock vote together as a single class on all matters submitted to a vote of stockholders except as required by law or as provided in EVgo’s Charter. The 5,750,000 shares of Class B common stock of CRIS held by the founders of CRIS prior to the CRIS Business Combination automatically converted into shares of Class A common stock on a one-for-one basis.

Commitments and Contingencies	Note 13 – Commitments and Contingencies Pilot Infrastructure Agreement On July 5, 2022, EVgo entered into a charging infrastructure agreement (the “Pilot Infrastructure Agreement”) and an operations and maintenance agreement (the “Pilot O&M”) with Pilot Travel Centers LLC (“Pilot Company”) and General Motors LLC (“GM”) to build, operate and maintain up to 2,000 stalls served by DC chargers that Pilot Company will own. The stalls will be located at Pilot Company sites across the United States. Pursuant to the Pilot Infrastructure Agreement, EVgo is required to meet certain construction milestones measured by the number of sites commissioned, and Pilot Company is required to make certain payments each month based on completion of pre-engineering and development work, the progress of construction at each site and for each charger procured by EVgo. Subject to extensions of time for specified excusable events, if EVgo is unable to meet its commissioning obligations, Pilot Company will be entitled to liquidated damages calculated per day, subject to a cap of $30,000 at each site. The Pilot Infrastructure Agreement contains various provisions that may permit or cause early termination, including Pilot Company’s right to terminate after 1,000 stalls have been completed, the inability of EVgo to secure certain chargers and a material increase in the price of chargers due to a change in law. If Pilot Company elects to terminate the Pilot Infrastructure Agreement after 1,000 stalls have been completed, Pilot Company must pay EVgo a termination fee per stall for those not built; such fee varies based on the number of stalls already built. If EVgo is wholly or partially unable to perform its obligations under the Pilot Infrastructure Agreement due to certain circumstances outside its control, including delays by permitting authorities and utilities or certain force majeure events, such inability will not be considered a breach or default under the Pilot Infrastructure Agreement. Under the Pilot O&M, EVgo is required to perform operations, maintenance and networking services on stalls built and commissioned under the Pilot Infrastructure Agreement in exchange for payment of a monthly fee by Pilot to EVgo. EVgo is subject to certain performance criteria under the Pilot O&M. Delta Charger Supply Agreement and Purchase Order On July 12, 2022, EVgo entered into a General Terms and Conditions for Sale of EV Charger Products (the “Delta Charger Supply Agreement”) with Delta Electronics, Inc. (“Delta”), including an initial purchase order (the “Purchase Order”), pursuant to which EVgo will purchase and Delta will sell EV chargers manufactured by Delta in specified quantities at certain delivery dates. EVgo expects to use a portion of the chargers purchased under the Purchase Order to meet the requirements of the Pilot Infrastructure Agreement. EVgo is required to purchase a minimum of 1,000 chargers from Delta under the Purchase Order and may, at EVgo’s election, increase the number of chargers it purchases from Delta to 1,100. General Motors Agreement On July 20, 2020, EVgo entered into a five-year contract with GM (the “GM Agreement”) to build 2,750 fast charger stalls that EVgo will own and operate as part of the Company’s public network. The GM Agreement has been amended twice to expand the overall number of charger stalls to be installed to 3,250, adjust charger stall installation targets, extend the completion deadline to March 31, 2026, and provide for a payment of $7,000,000 in December 2022 in exchange for EVgo’s agreement to apply certain branding decals on the fast chargers funded by GM pursuant to the GM Agreement and maintain a specified uptime percentage (described below) over the term of the agreement. Pursuant to the GM Agreement, EVgo is required to meet certain quarterly milestones measured by the number of charger stalls installed, and GM is required to make certain payments based on charger stalls installed. Under the GM Agreement, EVgo is required to install a total of 3,250 charger stalls by March 31, 2026, 44% of which are required to be installed by December 31, 2023. Meeting these milestones will require additional funds beyond the amounts committed by GM, and EVgo may face delays in construction, commissioning or aspects of installation of the charger stalls the Company is obligated to develop. EVgo is also required to maintain network availability (i.e., the percentage of time a charger is operational and available on the network) of at least 95%. In addition to the capital build program, EVgo is committed to providing GM EV customers with reservations and certain EVgo services at a discounted rate and branding on chargers. The contract is accounted for under ASC 606, which includes performance obligations related to reservations, memberships, and branding. The capital-build program is considered a set-up activity and not a performance obligation under ASC 606. The GM Agreement is subject to early termination in certain circumstances, including in the event EVgo fails to meet the quarterly charger stall-installation milestones or maintain the specified level of network availability. If GM opts to terminate the agreement, EVgo may not be entitled to receive continued payments from GM and instead may be required to pay liquidated damages to GM. In the event EVgo fails to meet a charger stall-installation milestone or maintain the required network availability in a calendar quarter, GM has the right to provide EVgo with a notice of such deficiency within 30 days of the end of the quarter. If the same deficiency still exists at the end of the quarter immediately following the quarter for which a deficiency notification was delivered, GM may immediately terminate the agreement and seek pre-agreed liquidated damages of up to $15.0 million. If EVgo does not meet its charger stall-installation milestone in any period, GM will have the right, if it so chooses, to send EVgo a charger stall count breach notice, which would trigger a cure period. It is possible that EVgo will not meet the charger stall-installation milestones under the GM Agreement in the future, particularly as a consequence of delays in permitting, commissioning and utility interconnection, including delays associated with the COVID-19 pandemic, as well as industry and regulatory adaptation to the requirements of high-powered charger installation, including slower than expected third-party approvals of certain site acquisitions and site plans by utilities and landowners, and supply chain issues. Nissan Agreements EVgo has executed two agreements with Nissan North America, Inc. (“Nissan”) under which EVgo has provided charger construction and installation and certain other services. Pursuant to the first agreement (the “Nissan 1.0 Agreement”), the Company was required to support, maintain and make available at least 850 chargers through July 2021, and purchasers or lessees of Nissan LEAF EVs in certain markets could receive charging services at EVgo stations or participating third-party charging stations. The Company fulfilled all build, support and maintenance obligations under the Nissan 1.0 Agreement. The second agreement between EVgo and Nissan, entered into in June 2019 (the “Nissan 2.0 Agreement”), provides for joint marketing activities, charging credit programs for purchasers or lessees of Nissan EVs, and a capital-build program. The Nissan 2.0 Agreement has been amended several times, including most recently in the fourth quarter of 2022 (the “Nissan Amendment”) to, among other things, adjust the allocation of the value of unused charging credits and to provide new offerings for purchasers or lessees of certain Nissan EV models. Under the joint-marketing activities provisions of the Nissan 2.0 Agreement, EVgo is obligated to spend a specified amount annually on joint-marketing activities that are mutually agreed-upon with Nissan. Under the charging credit program provisions in the Nissan 2.0 Agreement, credits for charging are allocated to purchasers or lessees of Nissan EVs, and such purchasers or lessees are permitted to charge their EV for 12 months at no charge to the participant, up to the amount of the charging credit allocated to such participant or on an unlimited basis, depending on the model of Nissan EV purchased or leased. In the event a participant does not use the entire amount of the allocated charging credit or if the annual charging credit pool is not exhausted within a specific period, a portion of the remaining dollar value of such credit rolls over to subsequent periods, and a portion is retained by the Company. For Nissan EV purchasers or lessees receiving unlimited charging, the Company receives an upfront activation fee for each purchaser or lessee as well as a usage-based fee. The capital-build program provided for in the Nissan 2.0 Agreement requires the Company to install, operate and maintain public, high-power dual-standard chargers in specified markets pursuant to a schedule that outlines the build timelines for the chargers to be constructed (the “Build Schedule”). If the Company fails to meet its Build Schedule obligations, Nissan may invoke a penalty of up to $70,000 per delayed site beyond a designated cure period, which could result in an adjustment to the consideration received by the Company under the Nissan 2.0 Agreement. EVgo and Nissan previously agreed to amend the Nissan 2.0 Agreement to extend the installation deadlines under the Build Schedule by up to 12 months, and Nissan has waived penalties for installation delays relating to program year one. The contract is accounted for under ASC 606, which includes performance obligations related to memberships, charging credits, and joint marketing activities. The capital-build program is considered a set-up activity and not a performance obligation under ASC 606. EVgo’s ability to meet its Build Schedule obligations may be impacted by delays in permitting, commissioning and utility interconnection, including delays associated with the COVID-19 pandemic, as well as industry and regulatory adaptation to the requirements of high-powered charger installation, including slower than expected third-party approvals of certain site acquisitions and site plans by utilities and landowners, and supply chain issues. Legal Proceedings In the ordinary course of the Company’s business, the Company may be subject to lawsuits, investigations, claims and proceedings, including, but not limited to, contractual disputes with vendors and customers and liabilities related to employment, health and safety matters. The Company accrues for losses that are both probable and reasonably estimable. Loss contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex and subject to change. Contingent liabilities arising from ordinary course litigation are not expected to have a material adverse effect on the Company’s financial position. However, future events or circumstances, currently unknown to management, may potentially have a material effect on the Company’s financial position, liquidity or results of operations in any future reporting period. Purchase Commitments As of December 31, 2022, EVgo had $114.7 million in outstanding purchase order commitments to EVgo’s contract manufacturers and component suppliers for charging equipment, all of which was short-term. In certain instances, EVgo is permitted to cancel, reschedule or adjust these orders. EVgo also had $3.2 million in commitments to other vendors, of which $1.9 million was short-term.

Fair Value Measurements
Fair Value Measurements	Note 15 – Fair Value Measurements The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). See Note 2 for additional information, including the fair value hierarchy. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicates the level within the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value as of December 31, 2022 and 2021: December 31, December 31, 2022 2021 (in thousands) Level Balance Level Balance Cash equivalents Money market funds 1 $ 150,125 — $ — Total assets $ 150,125 $ — Liabilities Earnout liability 3 $ 1,730 3 $ 5,211 Warrant liability – Public Warrants 1 10,164 1 39,614 Warrant liability – Private Placement Warrants 2 2,140 3 8,847 Total liabilities $ 14,034 $ 53,672 The following table presents a reconciliation for all liabilities measured and recognized at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2022 and 2021: Private Placement Warrant Earnout (in thousands) Liability Liability Fair value as of December 31, 2020 $ — $ — Liability recognized due to the CRIS Business Combination 35,654 18,278 Liability settled through equity — (10,853) Change in fair value of liability (19,742) (2,214) Transfers out of Level 3 (7,065) — Fair value as of December 31, 2021 8,847 5,211 Change in fair value of liability (4,912) (3,481) Transfers out of Level 3 (3,935) — Fair value as of December 31, 2022 $ — $ 1,730 Assumptions used in the valuations of the Private Placement Warrant liability were as follows: December 31, 2021 Stock price $ 9.94 Risk-free interest rate 1.19 % Expected term (in years) 4.5 Expected volatility 75 % Dividend rate — % Exercise price $ 11.50 Assumptions used in the valuations of the earnout liability are as follows: December 31, December 31, 2022 2021 Stock price $ 4.47 $ 9.94 Risk-free interest rate 4.16 % 1.19 % Expected term (in years) 3.2 4.8 Expected volatility 90 % 75 % Dividend rate — % — %

Warrant Liability
Warrant Liability	Note 16 – Warrant Liability The Public Warrants became exercisable on October 2, 2021. The Public Warrants will expire five years after the completion of an Initial Business Combination or earlier upon redemption or liquidation. As of December 31, 2022, there were 14,948,551 Public Warrants and 3,148,569 Private Placement Warrants outstanding. The Company will not be obligated to deliver any shares of Class A common stock pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A common stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue any shares of Class A common stock upon exercise of a warrant unless the share of Class A common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. The Company will use its commercially reasonable efforts to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed, as specified in the warrant agreement; provided that if shares of the Class A common stock are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but it will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. Such registration statement was initially filed on July 20, 2021 and declared effective on July 30, 2021. Redemption of warrants when the price per Class A common stock equals or exceeds $18.00 . ● ● ● ● if and only if, the last reported sale price of the Class A common stock for any 20 trading days within a 30 - trading day period ending three trading days before the Company sends to the notice of redemption to the warrant holders (“Reference Value”) equals or exceeds $18.00 per share (as adjusted). Redemption of warrants when the price per Class A common stock equals or exceeds $10.00 . ● ● at a price of $0.10 per warrant upon a minimum of 30 days ’ prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares, based on the redemption date and the fair market value of the Class A common stock; ● if and only if, the Reference Value equals or exceeds $10.00 per share (as adjusted); and ● if the Reference Value is less than $18.00 per share (as adjusted), the Private Placement Warrants must also concurrently be called for redemption on the same terms as the outstanding Public Warrants, as described above. The exercise price and number of Class A common stock issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for the issuance of Class A common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. The Public Warrants may be exercised only for a whole number of shares. The Private Placement Warrants are identical to the Public Warrants underlying the units sold in the Initial Public Offering, except that the Private Placement Warrants and the shares of Class A common stock issuable upon the exercise of the Private Placement Warrants are entitled to certain registration rights pursuant to the Registration Rights Agreement, dated as of July 1, 2021, by and among the Company, the Sponsor, certain other initial stockholders, and Holdings. Additionally, the Private Placement Warrants are exercisable for cash or on a cashless basis, at the holder’s option and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees (except for a number of shares of Class A common stock as described above under “ — Redemption of warrants when the price per Class A common stock equals or exceeds $18.00 ” and “— Redemption of warrants when the price per Class A common stock equals or exceeds $10.00 ”

The estimated fair value of the 1,437,500 Earnout Shares issued and outstanding at the closing of the CRIS Business Combination on July 1, 2021 was $18.3 million based on a Monte Carlo simulation valuation model using a distribution of potential outcomes on a monthly basis over the Earnout Period using the most reliable information available. On July 2, 2021, the $12.50 Triggering Event occurred and, as a result, 718,750 Earnout Shares valued at $10.9 million were deemed to be earned and reclassified into equity on that date. The estimated fair value of the earnout liability related to the 718,750 Earnout Shares subject to the $15.00 Triggering Event originally valued at $8.8 million was $1.7 million and $5.2 million as of December 31, 2022 and 2021, respectively. The change in fair value of the earnout liability resulted in a gain of $3.5 million and $2.2 million recognized in the consolidated statements of operations for the years ended December 31, 2022 and 2021, respectively (see Note 15).

Income Taxes
Income Taxes	Note 18 – Income Taxes The provision for income taxes consists primarily of income taxes related to federal and state jurisdictions where business is conducted related to the Company’s ownership in EVgo OpCo. All income (loss) before income taxes is generated in the U.S. For the years ended December 31, 2022 and 2021, the Company’s provision for income taxes and effective tax rates were deemed to be de minimis. Prior to July 1, 2021, the Company was not a taxable entity for U.S. federal income tax purposes or for any of the states in which the Company operated. On July 1, 2021, pursuant to the CRIS Business Combination, the Company became a taxable entity for U.S. federal income tax purposes and for all of the states in which the Company operates. Due to operating losses in the years ended December 31, 2022 and 2021, the Company’s effective tax rate was zero. The provision for income taxes differs from the amount computed by applying the U.S. corporate statutory income tax rate to loss before income taxes for the reasons set forth below: Years Ended December 31, 2022 2021 Statutory federal income tax rate 21.00 % 21.00 % State taxes, net of federal tax benefit 6.36 6.28 Net loss attributable to NCI/non-taxable partnership structure (25.64) (32.10) Change in fair value of warrant liability 9.43 14.69 Tax credits 1.10 0.89 Other permanent items (0.29) (0.06) Change in fair value of earnout liability 0.91 1.05 Transaction costs — 0.67 Change in valuation allowance (12.87) (12.42) Effective tax rate — % — % Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as net operating loss and tax credit carryforwards. There were no net deferred tax assets and no net deferred tax liabilities as of December 31, 2022 and 2021. The significant components of the Company’s deferred tax assets as of December 31, 2022 and 2021 were as follows: December 31, December 31, (in thousands) 2022 2021 Deferred tax assets: Investment in partnership $ 119,033 $ 115,667 Tax credit carryforwards 1,537 513 Net operating loss carryforwards 13,794 6,048 Total deferred tax assets 134,364 122,228 Less valuation allowance (134,364) (122,228) Deferred tax assets, net of valuation allowance $ — $ — In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Management considered all available material evidence, both positive and negative, in assessing the appropriateness of a valuation allowance for the Company’s deferred tax assets, including the generation of future taxable income, the scheduled reversal of deferred tax liabilities and other available material evidence. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance against its net deferred tax assets as of December 31, 2022 and 2021. As of December 31, 2022 and 2021, EVgo had $50.3 million and $22.0 million, respectively, in federal net operating losses with an indefinite carryforward period, tax credits of $1.5 million and $0.5 million, respectively, which will start expiring in 2041, and state net operating losses with various expiration periods. The Company files income tax returns in the U.S. federal jurisdiction and in various state and local jurisdictions and is subject to examination by the various taxing authorities for all periods since its inception. As of December 31, 2022 and 2021, there were no unrecognized tax benefits for uncertain tax positions, nor any amounts accrued for interest and penalties.

Tax Receivable Agreement
Tax Receivable Agreement	Note 19 – Tax Receivable Agreement In connection with the CRIS Business Combination, EVgo entered into a tax receivable agreement (the “Tax Receivable Agreement”) with EVgo Holdings (along with permitted assigns, the “TRA Holders”) and LS Power Equity Advisors, LLC, as agent. The Tax Receivable Agreement generally provides for payment by the Company, Thunder Sub or any of their subsidiaries (other than EVgo OpCo and its subsidiaries) (“Company Group”) to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes or is deemed to realize in certain circumstances after the CRIS Business Combination as a result of (i) certain increases in tax basis that occur as a result of the Company Group’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of the TRA Holders’ EVgo OpCo Units pursuant to the CRIS Business Combination or the exercise of the redemption or Call Rights set forth in the EVgo OpCo A&R LLC Agreement and (ii) imputed interest deemed to be paid by the Company Group as a result of and additional tax basis arising from, any payments the Company Group makes under the Tax Receivable Agreement. The Company Group will retain the benefit of any remaining net cash savings. If the Company Group elects to terminate the Tax Receivable Agreement early (or it is terminated early due to the Company Group’s failure to honor a material obligation thereunder or due to certain mergers, asset sales, other forms of business combinations or other changes of control), the Company Group is required to make an immediate payment equal to the present value of the anticipated future payments to be made by it under the Tax Receivable Agreement (based upon certain assumptions and deemed events set forth in the Tax Receivable Agreement, including (i) that the Company Group has sufficient taxable income on a current basis to fully utilize the tax benefits covered by the Tax Receivable Agreement and (ii) that any EVgo OpCo Units (other than those held by the Company Group) outstanding on the termination date or change of control date, as applicable, are deemed to be redeemed on such date). Amounts payable by the Company under the Tax Receivable Agreement are accrued through a charge to income when it is probable that a liability has been incurred and the amount is estimable. During the years ended December 31, 2022 and 2021, no transactions occurred that would result in a cash tax savings benefit that would trigger the recording of a liability by the Company based on the terms of the Tax Receivable Agreement.

Share-Based Compensation	Note 20 – Share-Based Compensation The following table sets forth the Company’s total share-based compensation expense included in the Company’s consolidated statements of operations: Years Ended December 31, (in thousands) 2022 2021 Cost of sales $ 119 $ 33 General and administrative expenses 24,929 10,909 Total share-based compensation expense $ 25,048 $ 10,942 2021 Long Term Incentive Plan On July 1, 2021, concurrent with the closing of the CRIS Business Combination, stockholders approved the Board of Directors-approved 2021 Long Term Incentive Plan (the “2021 Incentive Plan”). The 2021 Incentive Plan reserves 33,918,000 shares of Class A common stock for issuance to employees, non-employee directors and other service providers. As of December 31, 2022, there were 28,968,027 shares of Class A common stock available for grant. The 2021 Incentive Plan provides for potential grants of: (i) incentive stock options qualified as such under U.S. federal income tax laws; (ii) stock options that do not qualify as incentive stock options; (iii) stock appreciation rights; (iv) restricted stock awards; (v) restricted stock units (“RSUs”); (vi) vested stock awards; (vii) dividend equivalents; (viii) other share- or cash-based awards; (ix) cash awards; and (x) substitute awards. Unless earlier terminated by action of the Company’s Board of Directors, the 2021 Incentive Plan will terminate on the tenth anniversary of the 2021 Incentive Plan’s effective date of March 26, 2021. Stock Options The Company commenced granting stock options to certain senior employees in 2022. Compensation expense related to share-based awards is measured and recognized in the financial statements based on the fair value of the awards granted. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and recognized on a straight-line basis over the requisite service period. The options vest annually over a three-year period and have a term of 10 years. The following table summarizes stock option activity for the year ended December 31, 2022: Weighted Average Shares Underlying Weighted Average Remaining Aggregate (shares in thousands) Options Exercise Price Contractual Life Intrinsic Value Outstanding as of December 31, 2021 — Granted 375 $ 12.86 Outstanding as of December 31, 2022 375 $ 12.86 9.2 years $ — As of December 31, 2022, the Company’s unrecognized share-based compensation expense related to stock options was approximately $1.6 million, which is expected to be recognized over a period of 1.5 years. The weighted average grant date fair value per share of options granted during the year ended December 31, 2022 was $8.79 . There were no stock options vested or exercisable as of December 31, 2022. The fair value of the stock options granted during the year ended December 31, 2022 was computed using Black-Scholes option-pricing model using the following key assumptions: Risk-free interest rate 2.5 % Dividend yield — % Expected volatility 81.4 % Expected life (in years) 5.67 Risk-free interest rate. Dividend yield. Expected volatility. Expected life. Restricted Stock Units RSUs granted by EVgo typically vest annually over a period of three years from the date of grant. The fair value of RSUs is calculated based on the closing price of the Company’s Class A common stock on the grant date. The table below represents the Company’s RSU activity under the 2021 Incentive Plan during the years ended December 31, 2022 and 2021: Weighted Average Number of Grant Date (shares in thousands) Shares Fair Value Nonvested as of December 31, 2020 — $ — Granted 1,988 $ 11.40 Forfeited (33) $ 11.55 Nonvested as of December 31, 2021 1,955 $ 11.40 Granted 3,059 $ 10.76 Vested (645) $ 11.39 Forfeited (439) $ 11.84 Nonvested as of December 31, 2022 3,930 $ 10.85 The total fair value of RSUs vested during the year ended December 31, 2022 was $7.1 million. No RSUs vested during the year ended December 31, 2021. As of December 31, 2022, the Company’s unrecognized share-based compensation expense related to unvested RSUs was approximately $19.7 million, which is expected to be recognized over a period of 1.5 years. EVgo Management Holdings, LLC Incentive Units Following the Holdco Merger and prior to the CRIS Business Combination, all employees of EVgo Services received share-based compensation in the form of units in EVgo Management Holdings, LLC (“EVgo Management”) that track incentive units issued by EVgo Holdings to EVgo Management (“Incentive Units”). The EVgo Holdings LLCA provides for the issuance of 1,000,000 Incentive Units. Each Incentive Unit grants a profits interest in EVgo Holdings, which can generally be described as a participation interest whose right to receive distributions is determined by the cumulative amount of distributions (cash or in-kind) received by each outstanding Capital Unit in EVgo Holdings up to and including the date of a distribution. Distributions to the Incentive Unit holders are made solely from cash or property of EVgo Holdings. Incentive Unit holders have no claim as to the cashflow or assets of EVgo Holdco or EVgo Services. The Incentive Units were awarded pursuant to the EVgo Holdings LLCA and consequently the limited liability agreement of EVgo Management and individual grant agreements. These agreements include limitations with respect to the distribution entitlements of such Incentive Units and limitations imposed in order to cause such Incentive Units to qualify as “profits interests” within the meaning of Internal Revenue Service Revenue Procedures 93-27 and 2001-43, Internal Revenue Service Notice 2005-43, or any future Internal Revenue Service guidance. Specifically, such limitations were established such that any holder of Incentive Units will participate only in the post-grant appreciation in value of EVgo Holdings. As a result, the Incentive Units essentially have no value on the date of grant. Of each individual grant of Incentive Units, a portion was designated as time vesting (the “Time Vesting Incentive Units”) and the remaining portion was designated as sale vesting (the “Sale Vesting Incentive Units”). The Time Vesting Incentive Units vest annually and equally over a period of four years from the date of grant. Sale Vesting Incentive Units vest based upon the achievement of certain trigger events relating to the sale of EVgo Holdings. The Company determined the Incentive Units and resulting profits interest are equity-classified requiring application of ASC 718. Under ASC 718, share-based payment awards are initially measured at the fair value of the equity instruments that the entity is required to issue when the employee becomes entitled to the instrument (i.e., when all service, performance, market and/or other conditions have been met). The estimate of fair value should be based on share price and other factors at the grant date and should incorporate the effect of any restrictions or conditions that continue in effect after the vesting date. For equity-classified awards, changes in the share price or other pertinent variable, such as volatility or the risk-free rate, subsequent to the grant date would not cause the fair value estimate to be remeasured. The Company has elected to use the straight-line approach to recognize compensation cost for the Time Vesting Incentive Units awards. No compensation cost will be recognized for the Sale Vesting Incentive Units until such time that an event as described above occurs. The Company has elected to account for forfeitures as they occur. The Company has recorded expense related to the Time Vesting Incentive Units over the vesting term based on a fair value calculated using the Monte Carlo simulation model in conjunction with the Finnerty Model. The assumptions underlying the simulation are noted in the following table for the year ended December 31, 2021: Annual risk-free rate of return 0.32 % Expected volatility 37.2 % Expected term (in years) 4.0 Dividend yield — % Presented below is a summary of the activity of the Company’s Incentive Units for the years ended December 31, 2022 and 2021: Weighted Average Grant Date (shares in thousands) Units Fair Value Outstanding at December 31, 2020 640 $ 9.44 Granted 143 $ 51.11 Vested (104) $ 9.44 Forfeited (20) $ 18.77 Outstanding at December 31, 2021 659 $ 18.19 Vested (123) $ 17.08 Forfeited (65) $ 16.76 Outstanding at December 31, 2022 471 $ 18.68 As of December 31, 2022, the Company’s unrecognized share-based compensation expense related to unvested Incentive Units was approximately $7.0 million, which is expected to be recognized over a period of 1.7 years.

Net Loss Per Share	Dec. 31, 2022
Net Loss Per Share
Net Loss Per Share	Note 21 – Net Loss Per Share Basic and diluted earnings per common share ( “ ” Basic EPS is generally calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS is generally calculated by dividing net income (loss) attributable to common stockholders adjusted for the effects of any dilutive securities by the weighted average number of common shares outstanding plus the additional dilution for all potentially dilutive securities. During loss periods, diluted loss per share is based on the weighted average number of common shares outstanding (basic), because the inclusion of common stock equivalents would be antidilutive. The following table sets forth the computation of basic and diluted net income (loss) per share for the years ended December 31, 2022 and 2021: Years Ended December 31, (in thousands, except per share data) 2022 2021 Numerator Net loss $ (106,240) $ (57,762) Less: net loss attributable to redeemable noncontrolling interest (78,665) (51,856) Net loss attributable to Class A common stockholders (27,575) (5,906) Less: net loss attributable to participating securities (285) (62) Net loss attributable to Class A common stockholders, basic and diluted $ (27,290) $ (5,844) Denominator Weighted average common stock outstanding 69,433 68,734 Less: weighted average unvested Earnout Shares outstanding (719) (719) Weighted average common stock outstanding, basic and diluted 68,714 68,015 Net loss per share – basic and diluted $ (0.40) $ (0.09) Prior to the consummation of the CRIS Business Combination, EVgo OpCo was wholly owned by EVgo Holdings. In connection with the CRIS Business Combination, EVgo Holdings contributed all of the equity interests in EVgo Holdco to EVgo OpCo in exchange for 195,800,000 EVgo OpCo Units, the Company contributed all of its assets and 195,800,000 shares of Class B common stock to Thunder Sub, Thunder Sub transferred 195,800,000 shares of Class B common stock and the right to enter into the Tax Receivable Agreement to EVgo Holdings and Thunder Sub contributed all of its remaining assets to EVgo OpCo in exchange for EVgo OpCo Units equal to the number of shares of Class A common stock outstanding. The shares of Class B common stock owned by EVgo Holdings have been evaluated and are excluded from net income or loss per share calculations as they do not participate in earnings or loss of the Company. Therefore, retrospective application of the conversion of these ownership interests into shares of Class B common stock would not result in an appropriate or meaningful presentation of EPS. Therefore, the EPS information presented only relates to the periods subsequent to the consummation of the CRIS Business Combination on July 1, 2021. The Company’s potentially dilutive securities consist of the Company’s Public Warrants, Private Placement Warrants, RSUs, stock options and unvested Earnout Shares.

Redeemable Noncontrolling Interest
Redeemable Noncontrolling Interest	Note 22 – Redeemable Noncontrolling Interest As of December 31, 2022, EVgo Holdings held 195,800,000 EVgo OpCo Units, representing a 73.6% economic ownership interest in EVgo OpCo (reflecting the exclusion of 718,750 shares of Class A common stock held by other entities that were subject to possible forfeiture) and a corresponding number of shares of Class B common stock, representing a 73.4% voting interest in the Company. EVgo Holdings is entitled to one vote per share of Class B common stock but is not entitled to receive dividends or any assets upon liquidation, dissolution, distribution or winding-up of the Company. Each EVgo OpCo Unit is redeemable, together with one share of Class B common stock, for either one share of Class A common stock or, at EVgo OpCo’s election, the cash equivalent market value of one share of Class A common stock in accordance with the terms of the EVgo OpCo A&R LLC Agreement (see Note 12). The EVgo OpCo Units held by EVgo Holdings have been classified as a redeemable noncontrolling interest in the Company. The cash redemption feature of the EVgo OpCo Units, together with a corresponding number of shares of Class B common stock, at the option of EVgo OpCo, is considered outside of the control of the Company. Therefore, in accordance with ASC Topic 480, Distinguishing Liabilities from Equity The redeemable noncontrolling interest held by EVgo Holdings in EVgo OpCo, through its ownership of EVgo OpCo Units, was initially measured at its carrying amount on the CRIS Close Date. Net income or loss and other comprehensive income or loss are attributed to the redeemable noncontrolling interest during each reporting period based on its ownership percentage, as appropriate. Subsequent to that, the redeemable noncontrolling interest is measured at its fair value (i.e., based on the Class A common stock price) at the end of each reporting period, with the remeasurement amount being no less than the initial carrying amount, as adjusted for the redeemable noncontrolling interest’s share of net income or loss and other comprehensive income or loss. The offset of any fair value adjustment is recorded to equity, with no impact to net income (loss). The table below presents the reconciliation of changes in redeemable noncontrolling interest for the period from the CRIS Close Date through December 31, 2022: (in thousands) Balance as of July 1, 2021 $ — Redeemable noncontrolling interest resulting from the CRIS Business Combination 436,739 Net loss attributable to redeemable noncontrolling interest for the period (16,824) Equity-based compensation attributable to redeemable noncontrolling interest during the period 1,040 Adjustment to revise redeemable noncontrolling interest to its redemption value at period-end 1,525,297 Balance as of December 31, 2021 1,946,252 Net loss attributable to redeemable noncontrolling interest for the period (78,665) Equity-based compensation attributable to redeemable noncontrolling interest during the period 1,878 Adjustment to revise redeemable noncontrolling interest to its redemption value at period-end (994,239) Balance as of December 31, 2022 $ 875,226

The awards will vest based on continued service, generally over a period of three years. The grant date fair value of the awards will be recognized as share-based compensation expense over the requisite service periods. Granting of 205 Petition On February 3, 2023, the Company filed a petition (the “Petition”) in the Court of Chancery under Section 205 of the Delaware General Corporation Law seeking (i) the validation of the stockholder vote approving CRIS’s certificate of incorporation in connection with the CRIS Business Combination (see Note 3) and (ii) the validation and declaration of effectiveness of (a) EVgo’s Charter (including its filing and effectiveness, in each case as of July 1, 2021) and (b) the securities issued or to be issued in reliance on such approval and/or the validity of EVgo’s Charter, as of the respective dates of their issuance (including the 5,750,000 shares of Class A common stock into which the shares of Class B common stock converted upon the consummation of the CRIS Business Combination). The Company filed the Petition due in part to a recent ruling of the Court of Chancery that created uncertainty as to the validity and effectiveness of these corporate acts and, consequently, as to the Company’s capital structure. Such purported uncertainty was eliminated on February 21, 2023, when, following a hearing of the Petition, the Court of Chancery issued an order validating each of the corporate acts described above, effective as of the time each such act was originally taken, notwithstanding any failures of authorization or potential failures of authorization described in, or resulting from the matters described in, the Petition.

Summary of Significant Accounting Policies
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The CRIS Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“GAAP”), primarily due to the fact that EVgo Holdings continues to control the Company through its ownership of the Company’s Class B common stock. As described in Note 1, EVgo Services was acquired by EVgo Holdco on the Holdco Merger Date and EVgo Holdco was partially acquired by EVgo through EVgo’s acquisition of EVgo OpCo Units, on the CRIS Close Date. The accompanying consolidated financial statements are presented in accordance with GAAP and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). References to GAAP issued by the Financial Accounting Standards Board (“FASB”) in these notes to the consolidated financial statements are to the FASB Accounting Standards Codification (“ASC”). The consolidated financial statements include the accounts of the Company and its subsidiaries and all intercompany transactions have been eliminated in consolidation. GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude and timing, certain subsequent events may be required to be reflected in the consolidated financial statements at the balance sheet date and/or required to be disclosed in the notes to the consolidated financial statements. The Company has evaluated subsequent events accordingly.
Use of Estimates	Use of Estimates The consolidated financial statements have been prepared in accordance with GAAP. The preparation of EVgo’s consolidated financial statements requires the Company to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses and related disclosures of contingent assets and liabilities. Significant estimates made by management include, but are not limited to, variable consideration estimates for revenue, depreciable lives of property and equipment and intangible assets, costs associated with asset retirement obligations, the fair value of share-based compensation, earnout liability, warrant liability and the fair value measurements of assets and liabilities allocated for acquired businesses. Management bases these estimates on its historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results experienced may vary materially and adversely from EVgo’s estimates. Revisions to estimates are recognized prospectively.
Reclassifications	For the years ended December 31, 2022 and 2021, EVgo had four and two vendors, respectively, that provided more than 10% of EVgo’s total charging equipment. For the years ended December 31, 2022 and 2021, the amount provided by these vendors were 88.8% and 37.3% , respectively. Reclassifications The Company has made certain reclassifications to prior period amounts to conform to current period presentation.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and restricted cash include cash held in cash depository accounts in major banks in the U.S. and are stated at cost. Cash equivalents are carried at fair value and are primarily invested in money market funds. Cash that is held by a financial institution and has restrictions on its availability to the Company is classified as restricted cash. The Company had unused letters of credit, which were collateralized with cash classified as restricted cash on the Company's consolidated balance sheets, of $0.7 million as of December 31, 2022 and 2021, associated with the construction of its charging stations and in connection with one of its operating leases.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are amounts due from customers under normal trade terms. Payment terms for accounts receivable related to capital-build agreements are specified in the individual agreements and vary depending on the counterparty. Management reviews accounts receivable on a recurring basis to determine if any accounts receivable will potentially be uncollectible. The Company reserves for any accounts receivable balances that are determined to be uncollectible in the allowance for doubtful accounts. After all attempts to collect an account receivable have failed, the account receivable is written-off against the allowance for doubtful accounts. Other accounts receivable of $1.3 million and a de minimis amount were included in accounts receivable, net, on the consolidated balance sheets as of December 31, 2022 and 2021, respectively.
Deferred Offering Costs	Deferred Offering Costs Deferred offering costs, consisting primarily of legal, accounting and filing fees relating to public offerings, are capitalized. The deferred offering costs will be offset against public offering proceeds upon the effectiveness of an offering. In the event that an offering is abandoned or terminated, deferred offering costs will be expensed. As of December 31, 2022 and 2021, the Company had capitalized $1.0 million and $0.2 million, respectively, of deferred offering costs in other current assets on the consolidated balance sheets.
Cloud Implementation Costs	Cloud Implementation Costs The Company capitalizes certain implementation costs incurred related to cloud computing arrangements that are service contracts. Such costs are amortized on a straight-line basis over the term of the associated hosting arrangement plus any reasonably certain renewal period. Any capitalized amounts related to such arrangements are recorded within prepaid expense and other current assets and within non-current assets on the consolidated balance sheets.
Property, Equipment and Software	Property, Equipment and Software Property and equipment includes land, charging stations and other technical installations, construction in process, charging station and related equipment and a building, which are stated at cost or at fair value as of the date of acquisition less accumulated depreciation and amortization. Land is not depreciated. Depreciation for property, equipment and software is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful life of the building is forty years and the estimated useful lives of the remaining assets are approximately three The Company has adopted the provisions of ASC Topic 350-40, Internal-Use Software,
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. The Company’s goodwill and intangible assets are the result of the Holdco Merger and as part of the acquisition of PlugShare LLC (f/k/a Recargo, Inc.) (see Note 3). EVgo completes an impairment test of goodwill at least annually or more frequently if facts or circumstances indicate that goodwill might be impaired. EVgo’s annual impairment test date is October 1st. Goodwill is tested for impairment at the reporting unit level. EVgo first performs a qualitative assessment of EVgo’s single reporting unit. Factors considered in the qualitative assessment include general macroeconomic conditions, industry and market conditions, cost factors, overall financial performance of EVgo’s reporting unit, events or changes affecting the composition or carrying amount of the net assets of EVgo’s reporting unit, any sustained decrease in EVgo’s share price and other relevant entity-specific events. If EVgo elects to bypass the qualitative assessment or if EVgo determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, a quantitative test would be required. EVgo then performs the goodwill impairment test for each reporting unit by comparing the reporting unit’s carrying amount, including goodwill, to its fair value, which is measured based upon, among other factors, a discounted cash flow analysis, as well as market multiples for comparable companies. Estimates critical to EVgo’s evaluation of goodwill for impairment include forecasts for revenue, EBITDA growth and long-term growth rates, as well as the discount rates. If the carrying amount of the reporting unit is greater than its fair value, goodwill is considered impaired. EVgo did not recognize any impairment losses for any periods presented. It is possible in future periods that further declines in market conditions, customer demand or other potential changes in operations may increase the risk that these assets may become impaired. Finite-lived intangible assets are amortized over their useful lives and recorded as either cost of sales or operating expenses depending on the nature of the intangible asset. Costs incurred to renew or extend the term of recognized intangible assets are expensed as incurred. During the fourth quarter of 2022, the Company reviewed its goodwill and other intangible assets for indicators of impairment and performed its annual goodwill impairment analysis as part of this review. The Company did not note any indicators of impairment with respect to its goodwill or other intangible assets as of December 31, 2022 and no impairment charge was required. Estimated useful lives of the Company’s intangible assets are presented below: Site Host relationships 12 years Customer relationships 4-5 years Developed technology 10-15 years User base 4 years Trade name 15-20 years Long-Lived Asset Impairment The Company reviews its long-lived assets, including property and equipment, right-of-use assets and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If the Company identifies events or changes in circumstances that could impact recoverability, the Company compares the carrying value of the assets or asset groups with their estimated future undiscounted cash flows. If it is determined that an impairment has occurred, the loss would be recognized during that period. The impairment loss would be calculated as the difference between the asset or asset group carrying values and the present value of estimated net cash flows or comparable market values, giving consideration to recent operating performance and pricing trends. EVgo did not recognize any impairment losses for any periods presented. It is possible in future periods that further declines in market conditions, customer demand or other potential changes in operations may increase the risk that these assets may become impaired. During the fourth quarter of 2022, the Company reviewed its long-lived assets for indicators of impairment, did not note any indicators of impairment and no impairment charge was required.

Lease Accounting	Lease Accounting The Company accounts for leases under ASC Topic 842, Leases The Company’s lease agreements primarily require lease payments based on a minimum annual rental amount. In addition to minimum lease payments, the Company’s lease agreements may contain variable lease payments based on revenue-sharing or inflation adjustments. The Company has elected the practical expedient to not separate non-lease components from lease components in the measurement of liabilities for all asset classes. Lease liabilities are recognized at the present value of the fixed lease payments using an implicit rate and, if not available, an incremental borrowing rate based on estimated collateralized borrowings available to the Company. The Company incurs initial direct costs and receives landlord incentives that increase or decrease the calculated right-of-use asset, respectively. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company expenses variable lease payments as incurred. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company has not entered into any finance leases. As a lessor, the Company has entered into agreements to lease charging equipment, charging stations and other technical installations or sublease properties leased from Site Hosts to third parties. The Company, at the inception of a lease contract, determines if it is an operating, sales-type or direct financing lease. The Company has not elected the practical expedient to not separate non-lease components from lease components in the measurement of liabilities for all asset classes. The leases generally provide for fixed monthly payments and sometimes include provisions for contingent variable rent based on the number of charging sessions and minutes used, which are recognized when earned. Fixed payments received under lease agreements for operating leases are recognized on a straight-line basis over the lease term and are reported in revenue in the consolidated statements of operations.
Deferred Revenue	Deferred Revenue Deferred revenue consists of billings on contracts where performance has commenced and payments have been received in advance of revenue recognition. Deferred revenue is recognized into revenue as the related revenue recognition criteria are met.
Customer Deposits	Customer Deposits Customer deposits include prepayments that are refundable. Once deposits are no longer refundable, the Company reclassifies the amounts related to those contracts to deferred revenue. Customer deposits are also comprised of funds that have been received to offset future expenses of the Company for certain marketing expenses reimbursed by customers.
Capital-Build Liability and Expense Reimbursements	Capital-Build Liability and Expense Reimbursements The Company receives grant funding in the form of cash from governmental and non-governmental entities to construct and operate EV chargers. As there is no authoritative guidance under GAAP regarding accounting for government assistance to for-profit business entities, the grants directly or indirectly provided by the government are accounted for by analogy to International Accounting Standard (“IAS”) 20, Accounting for Government Grants and Disclosure of Government Assistance Revenue from Contracts with Customers The charging stations purchased and installed under these programs or agreements are recorded in property and equipment. At the time the expenditures for the charging stations have been incurred, the funding associated with the charging station capital expenditure is deferred as a capital-build liability and amortized against depreciation expense over the remaining useful life of the related assets. The Company retains ownership of these charging stations. Reimbursement under the agreements for operating and maintenance expenses is recognized as an offset to cost of revenue in the consolidated statements of operations in the period in which EVgo recognizes the related costs of operation and maintenance of the chargers.
Derivatives Financial Instruments	Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging
Earnout Liability	Earnout Liability In accordance with ASC 815, Earnout Shares (as defined in Note 3) were initially recorded as a derivative liability at fair value as of the CRIS Close Date, since they are not indexed to the Company’s Class A common stock. They are subsequently remeasured at each reporting date through the change in fair value of earnout liability in the consolidated statements of operations. The estimated fair value of the contingent earnout liability is determined using a Monte Carlo simulation using a distribution of potential outcomes on a monthly basis over the Earnout Period (as defined in Note 17), prioritizing the most reliable information available. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including the current common stock price, expected volatility, risk-free rate, expected term and dividend rate. Until its settlement, the contingent earnout liability is categorized as a Level 3 (defined below) fair value measurement because the Company utilizes projections during the Earnout Period that include unobservable inputs. Contingent earnouts involve certain assumptions requiring significant judgment and actual results can differ from assumed and estimated amounts.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations represent the estimated present value of the amount the Company will incur for dismantling and restoring sites (locations owned by unrelated parties where the Company’s chargers are placed) at the end of their agreements, in accordance with their contractual terms. Upon initial recognition of the Company’s asset retirement obligation liability, property and equipment is increased by an amount offsetting the liability and depreciated over its useful life and the obligation is accreted to its estimated future value at the date of retirement. Subsequent to establishing an asset retirement obligation, downward revisions in the liability due to a change in the expected timing or amount of cash flows are recorded as corresponding decreases to the asset retirement costs; however, if the amount of the decrease exceeds the carrying value of the related asset retirement cost and related asset, such excess credits are adjusted through a reduction of accretion expense. Asset retirement obligations require the use of estimates to determine third-party costs for dismantling and restoring the sites. Discount rates are also included to present value these costs, which are then accreted to the date the Company expects to remove the corresponding asset. Discount rates are based on the Company’s estimated credit adjusted risk-free rate. The Company reviews its estimates of removal costs on an ongoing basis and makes changes to the asset retirement obligations as necessary.
Warrant Liability	Warrant Liability The Company accounts for its issued and outstanding warrants (as described in Note 16) in accordance with the guidance contained in ASC 815, under which the warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the warrants as liabilities at their fair value and adjusts the warrants to fair value at the end of each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised or redeemed by the Company and any change in fair value is recognized in the statements of operations. The fair value of the redeemable warrants (the “Public Warrants”), originally sold as part of the units issued in the Company’s Initial Public Offering, has been estimated using the closing price of the Public Warrants as of December 31, 2022 and 2021. The Private Placement Warrants were initially valued using a Monte Carlo simulation model, which was a level 3 (defined below) fair value measurement. Commencing June 30, 2022, the fair value of the Private Placement Warrants was measured by reference to the trading price of the Public Warrants, which is considered to be a Level 2 (defined below) fair value measurement.
Fair Value Measurements	Fair Value Measurement The Company determines fair value in accordance with ASC 820, Fair Value Measurement Details on the methods and assumptions used to determine the fair values are as follows: ● Fair value measurements based on Level 1 inputs: Measurements that are most observable and are based on quoted prices of identical instruments obtained from the principal markets in which they are traded. Closing prices are both readily available and representative of fair value. Market transactions occur with sufficient frequency and volume to assure liquidity. ● Fair value measurements based on Level 2 inputs (“Level 2”): Measurements derived indirectly from observable inputs or from quoted prices from markets that are less liquid are considered Level 2. ● Fair value measurements based on Level 3 inputs: Measurements that are least observable are estimated from significant unobservable inputs determined from sources with little or no market activity for comparable contracts or for positions with longer durations. The carrying values of certain accounts such as accounts receivable, accounts payable and accrued expenses are deemed to approximate their fair values due to their short-term nature. The fair values of the Company’s money market funds are based on quoted prices in active markets for identical assets.
Revenue Recognition	Revenue Recognition The Company’s sources of revenue are from retail, commercial and OEM charging contracts, regulatory credits, OEM network contracts, eXtend, and ancillary services. Its primary source of revenue is charging contracts with customers. A significant portion of the Company’s charging contracts have upfront payment terms or monthly payment terms. Payments for walk-up retail charging usage are collected at the point of service, except for monthly member fees and member usage fees which are billed monthly in arrears. Payments for development and project management revenue occur either on an installment basis or are received upon completion of milestones. Payment terms vary on a contract-by-contract basis, although terms generally include a requirement of payment within 30 to 60 days. Revenues for regulatory credits such as LCFS credit sales are recognized upon delivery. The Company recognizes revenue pursuant to ASC 606, using a five-step model: (a) identification of the contract, or contracts, with a customer; (b) identification of the performance obligations in the contract; (c) determination of the transaction price; (d) allocation of the transaction price to the performance obligations in the contract; and (e) recognition of revenue when, or as, it satisfies a performance obligation. The transaction price for each contract is determined based on the amount the Company expects to be entitled to receive in exchange for transferring the promised products or services to the customer. Collectability of revenue is reasonably assured based on historical evidence of collectability of fees the Company charges its customers. The transaction price in the contract is allocated to each distinct performance obligation in an amount that represents the relative amount of consideration expected to be received in exchange for satisfying each performance obligation. Revenue is recognized when performance obligations are satisfied. At contract inception, the Company determines whether it satisfies the performance obligation over time or at a point in time. Revenue is recorded based on the transaction price excluding amounts collected on behalf of third parties such as sales taxes, which are collected on behalf of and remitted to governmental authorities. The Company may also incur fulfillment costs that are reimbursed by its customers as pass-through costs that may or may not be subject to a mark-up. Reimbursement for fulfillment costs is included in the transaction price and is recognized on a gross basis. The Company recognizes estimated losses on contracts immediately upon identification of the loss. Some of the Company’s contracts with customers only contain a single performance obligation. When agreements involve multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct. The Company applies significant judgment in identifying and accounting for each performance obligation, as a result of evaluating terms and conditions in contracts. The transaction price is allocated to each performance obligation based on the relative standalone selling price (“SSP”). The Company determines the SSP based on observable SSP when it is available, as well as other factors, including the price charged to its customers, its discounting practices and its overall pricing objectives, while maximizing observable inputs. EVgo’s contracts may provide its customers with the option to renew the agreement. Generally, this option is not considered to provide a material right that should be accounted for as a separate performance obligation because the customer would not receive a discount if it decided to renew and the option to renew is generally cancellable by either party subject to the notice of non-renewal requirements specified in the contract. If a material right is identified, the Company would account for these accordingly as separate performance obligations. EVgo’s contracts may also provide its customers with the option to purchase additional future services. Generally, this option is not considered to provide the customer with a material right that should be accounted for as a separate performance obligation since the cost of the additional future services are generally at market rates for such services and the Company is not automatically obligated to stand ready to deliver these additional goods or services because the customer may reject EVgo’s proposal. Areas of Judgment and Estimates The Company exercises judgment in determining which promises in a contract constitute performance obligations rather than set-up activities. The Company determines which activities under a contract transfer a good or service to a customer rather than activities that are required to fulfill a contract but do not transfer control of a good or a service to the customer. Determining whether obligations in a contract are considered distinct performance obligations that should be accounted for separately or as a single performance obligation requires significant judgment. In reaching its conclusion, the Company assesses the nature of each individual service offering and how the services are provided in the context of the contract, including whether the services are significantly integrated which may require judgment based on the facts and circumstances of the contract. Determining the relative SSP for contracts that contain multiple performance obligations requires significant judgment to appropriately determine the suitable method for estimating the SSP. The Company determines SSP using observable pricing when available, which takes into consideration market conditions and customer specific factors. When observable pricing is not available, the Company determines SSP using estimation techniques, but maximizes the use of observable inputs in these estimation techniques. The Company’s customer contracts may include variable consideration such as that due to the unknown number of users that will receive charging credits or an unknown number of sites that will receive maintenance services. The Company estimates variable consideration under the expected value method or the most likely amount method. If charging station installations are not completed by specified dates, the Company may be subject to installation penalties. The Company may also be subject to other penalties identified in the customer agreements upon failure to maintain specified network uptimes and for other contractual service requirements. Variable consideration for installation, service, and other penalties is estimated using the most likely amount method. Practical Expedients and Exemptions The Company elected the practical expedient to not adjust the consideration in a contract for the effects of a significant financing component if the Company expects, at contract inception, that the period between receipt of payment and the transfer of promised goods or services will be less than one year. In some cases, the Company receives payment in advance of the transfer of promised goods or services. For contracts in which revenue is recognized over time and the entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, the Company recognizes revenue at the amount to which it has the right to invoice. The Company does not disclose the transaction price allocated to remaining performance obligations for (i) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice and (ii) contracts with variable consideration allocated entirely to a single performance obligation. The Company’s remaining performance obligations under these contracts include providing charging services, branding services and maintenance services which will generally be recognized over the contract term. An asset is recognized for the incremental costs of obtaining a contract with a customer if the benefit of those costs is expected to be longer than one year. A practical expedient to expense costs as incurred for costs to obtain a contract with a customer is applied when the amortization period would have been one year or less. Contract costs are evaluated for impairment in accordance with ASC 310, Receivables Contract Balances Differences in the timing of revenue recognition, billings and cash collections result in contract assets and contract liabilities. Contract Assets Contract Liabilities EVgo’s contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period, when applicable. From time-to-time, the payment terms of contracts require the customer to make advance payments as well as interim payments as work progresses. These advance payments generally are not considered to contain a significant financing component.
Sales Tax Collected from Customers	Sales Tax Collected from Customers As a part of the Company’s normal course of business, sales taxes are collected from customers in accordance with local regulations. Sales taxes collected are remitted, in a timely manner, to the appropriate governmental tax authority on behalf of the customer. The Company’s policy is to present revenue and costs net of sales taxes.
Cost of Sales and General and Administrative Expenses	Cost of Sales and General and Administrative Expenses Cost of sales consists primarily of energy usage fees, depreciation, net of capital-build amortization expenses, site operating and maintenance expenses, customer service and network charges, warranty and repair services, site costs and related expense associated with charging equipment. General and administrative expenses primarily consist of payroll and related personnel expenses, IT and office services, office rent expense and professional services.
Advertising Costs	Advertising Costs Advertising costs are generally expensed as incurred and totaled $2.0 million and $1.6 million for the years ended December 31, 2022 and 2021, respectively.
Research and Development Costs	Research and Development Costs Research and development costs are expensed as incurred and totaled $4.8 million and $2.0 million for the years ended December 31, 2022 and 2021, respectively.
401(k) Plan	401(k) Plan The Company has a 401(k) plan that qualifies under Section 401(k) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). The 401(k) plan provides discretionary employer matching contributions to eligible employees up to 2% of an employee’s eligible gross pay up to IRS annual limits. Employer contributions to the 401(k) plan for the year ended December 31, 2022 were $0.7 million and de minimis for the year ended December 31, 2021.
Share-Based Compensation	Share-Based Compensation The Company recognizes compensation expense for all awards granted based on the grant date fair value. Compensation expense for awards that vest in increments is recognized based on an accelerated attribution method. In accordance with ASC Topic 718, Compensation – Stock Compensation
Income Taxes.	Income Taxes EVgo and Thunder Sub are each classified as a corporation for federal income tax purposes and are subject to U.S. federal and state income taxes. EVgo and Thunder Sub report U.S. federal income taxes on a consolidated basis and will be taxed at the prevailing corporate tax rates. EVgo and Thunder Sub include in income, for U.S. federal income tax purposes, their allocable portion of income from “pass-through” entities in which they hold an interest, including EVgo OpCo and its subsidiaries. “Pass-through” entities, such as EVgo OpCo and its subsidiaries, are not subject to U.S. federal and certain state income taxes at the entity level and instead, the tax liabilities with respect to taxable income are passed through to the members, including Thunder Sub. As a result, prior to the CRIS Business Combination, EVgo Holdco and its subsidiaries were not subject to U.S. federal income taxes at the entity level. The Company follows the asset and liability method of accounting for income taxes under ASC Topic 740, Income Taxes ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its tax positions. The Company is subject to income tax examinations by major taxing authorities since inception.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share represents net earnings (loss) attributable to common stockholders divided by the weighted average number of common shares outstanding during the period. The Company considers any Earnout Shares (as defined in Note 3) that are issued and outstanding but considered contingently returnable if certain conditions are not met, as participating securities due to their non-forfeitable right to receive dividends, requiring the use of the two-class method. Diluted earnings per share represents net earnings attributable to common stockholders divided by the weighted average number of common shares outstanding, inclusive of the dilutive impact of all potentially dilutive securities outstanding during the period, as applicable. Dilution is not considered when a net loss is reported.
Segment Reporting	Segment Reporting The Company’s chief operating decision-maker (“CODM”) is its Chief Executive Officer. Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by its CODM in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. As such, the Company has determined that it operates in one operating and reportable segment.
Newly Adopted Accounting Standards and Recently Issued Accounting Standards	Newly Adopted Accounting Standards In November 2021, the FASB issued Accounting Standards Update (“ASU”) 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance On May 3, 2021, the FASB issued ASU 2021-04, Earnings Per Shar (Topic 260) Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options In February 2016, the FASB issued ASC 842. Subsequent to the release of the initial ASU, the FASB issued various related corrective and clarifying ASUs for this topic, all of which have been codified in ASC 842. ASC 842 requires lessees to report most leases as assets and liabilities on the balance sheet. The Company adopted ASC 842 effective January 1, 2022, using the modified retrospective transition method as allowed under ASU 2018-11, Leases (Topic 842): Targeted Improvements Recently Issued Accounting Standards In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 guidance to alleviate the burden in accounting for reference rate reform by allowing certain expedients and exceptions in applying GAAP to contracts, hedging relationships and other transactions impacted by reference rate reform. The provisions apply only to those transactions that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. Adoption of the provisions of ASU 2020-04 are optional and are effective from March 12, 2020 through December 31, 2024, as amended by ASU 2022-06. As of December 31, 2022, the Company has not adopted any expedients and exceptions under ASU 2020-04.
