Note 2 — Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

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 accounting principles generally accepted in the United States of America (“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 and the fair value of share-based compensation, earnout liability and warrant liabilities. 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. 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 two customers that collectively comprised 45.7% of the Company’s total net accounts receivable as of December 31, 2023. The Company had one customer that comprised 20.5% of the Company’s total net accounts receivable as of December 31, 2022. For the year ended December 31, 2023, one customer represented 45.2% of total revenue. For the year ended December 31, 2022, two customers collectively represented 42.9% of total revenue.

For the year ended December 31, 2023, one vendor provided 76.9% of EVgo’s total charging equipment. For the year ended December 31, 2022, four vendors collectively provided 88.8% of EVgo’s total charging equipment.

Reclassifications

The Company has made certain reclassifications to prior period amounts to conform to the 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, 2023 and 2022, 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 $2.7 million and $1.3 million were included in accounts receivable, net, on the consolidated balance sheets as of December 31, 2023 and 2022, respectively.

Deferred Equity Issuance Costs

Deferred equity issuance costs, consisting primarily of legal, accounting and filing fees relating to public offerings, are capitalized. The deferred equity issuance costs are offset against public offering proceeds upon the effectiveness of an offering. In the event that an offering is abandoned or terminated, deferred equity issuance costs are expensed. As of December 31, 2023 and 2022, the Company had capitalized $0.8 million and $1.0 million, respectively, of deferred equity issuance 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 to seven years. Charging equipment and charging station installation costs are depreciated when they are placed into service. Construction in process consists primarily of charging equipment, charging station installation costs, and software that have not yet been placed into service and are not depreciated. Charging equipment consists primarily of equipment and various components that have not yet been allocated to a project. Leasehold improvements are amortized over the shorter of the estimated useful life or the lease term. Depreciation is reported net of the amortization of the capital-build liability. The cost of maintenance and repairs is charged to expense as incurred while significant renewals and betterments are capitalized. Deductions are made for retirements and/or disposals. Following the disposition of an asset, the associated net cost is no longer recognized as an asset, and any gain or loss on the disposition, inclusive of any amounts recovered from insurance, is reflected in general and administrative expenses.

The Company has adopted the provisions of ASC Topic 350-40, Internal-Use Software, and therefore the costs incurred in the preliminary stages of software development are expensed as incurred. The Company capitalizes all costs related to software developed or obtained for internal use when management commits to funding the project, the preliminary project stage is completed and when technological feasibility is established. Once a new functionality or improvement is released, the asset is subject to depreciation. Capitalization of costs ceases when the project is substantially complete and ready for its intended use and the costs are amortized into general and administrative expenses using the straight-line method over the estimated useful lives of the software assets, which is generally three years.

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. 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 1^st. 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 2023, 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 impairment with respect to its goodwill or other intangible assets as of December 31, 2023, 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 (“ROU”) 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.

Lease Accounting

The Company accounts for leases under ASC Topic 842, Leases (“ASC 842”). As a lessee, the Company enters into agreements with various Site Hosts, which allow the Company to lease space to operate the charging stations on their property and with various parties to lease its office, warehouse and laboratory space. The Company, at the inception of the contract, determines whether a contract is or contains a lease. For leases with an initial contractual term in excess of 12 months, the Company records the related operating or finance ROU asset and lease liability. The Company has elected to recognize leases with an initial term of 12 months or less on a straight-line basis without recognizing a ROU asset or operating lease liability. Some leases also include renewal and/or early termination options, which can be exercised under specific conditions. Renewal and termination options are not included in the measurement of the ROU assets and lease liabilities unless the Company is reasonably certain to exercise the options.

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 ROU 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.

Sale-leasebacks are transactions through which assets are sold at fair value and subsequently leased back. The resulting leases qualify and are accounted for as operating leases. Gains and losses on sale-leaseback transactions are recognized immediately. Failed sale-leaseback transactions are generally classified as finance leases and result in retention of the “sold” assets within land, buildings and equipment with a finance lease liability equal to the amount of proceeds received recorded as a component of other liabilities on the consolidated balance sheets.

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. Grant contracts provided by non-governmental entities are analyzed and if it does not fall under the scope of ASC 842 or ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), they are accounted for under IAS 20.

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 sales 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 (“ASC 815”). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the consolidated balance sheets as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet dates.

Earnout Liability

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 of Class A common stock (the “Earnout Shares”) if certain events do not occur. In accordance with ASC 815, the Earnout Shares are recorded as a derivative liability at fair value since they are not indexed to the Company’s Class A common stock. They are 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 14), 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 restriction period 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 Liabilities

The Company accounts for its issued and outstanding warrants (as described in Note 13) 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 Private Placement Warrants on the date of issuance and on each measurement date is estimated by reference to the trading price of the public warrants, which is considered a Level 2 (defined below) fair value measurement, or using a Monte Carlo simulation methodology, which is considered a Level 3 (defined below) fair value measurement and includes inputs such as EVgo’s stock price, the risk-free interest rate, the expected term, the expected volatility, the dividend rate, the exercise price and the number of Private Placement Warrants outstanding. Assumptions used in the Monte Carlo model are subjective and require significant judgment and actual results can differ from assumed and estimated amounts.

Fair Value Measurement

The Company determines fair value in accordance with ASC 820, Fair Value Measurement, which establishes a hierarchy for the inputs used to measure the fair value of financial assets and liabilities based on the source of the input, which generally range from quoted prices for identical instruments in a principal trading market (“Level 1”) to estimates determined using significant unobservable inputs (“Level 3”). Multiple inputs may be used to measure fair value; however, the level of fair value is based on the lowest significant input level within this fair value hierarchy. The Company’s recurring and non-recurring fair value measurements include the initial valuation of asset retirement obligations, the issuance of share-based compensation awards, the initial valuations of the assets and liabilities identified in purchase accounting, including intangible assets and property and equipment and the earnout and warrant liabilities.

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 cash, restricted cash, accounts receivable, prepaid expenses and other current assets, 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. There were no assets measured on a recurring basis using significant unobservable inputs (Level 3) as of December 31, 2023 and 2022.

Revenue Recognition

The Company’s sources of revenue are from retail, commercial and OEM charging, regulatory credit sales, OEM network, 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. Reimbursements for fulfillment costs are 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 a separate performance obligation. 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. Billing practices are governed by the terms of each contract based upon costs incurred, achievement of milestones and/or predetermined schedules. Billings do not necessarily correlate with the timing of revenue recognition such as revenue recognized over time using the relevant input method, which is generally either time-based or cost-based. Contract assets include unbilled amounts resulting from revenue under contracts when the time-based or cost-based method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract assets are classified as prepaid and other current assets on the consolidated balance sheets.

Contract Liabilities. The Company records contract liabilities when cash payments are received in advance of the Company’s performance of its obligations. Contract liabilities under the scope of ASC 606 include deferred revenue and

customer deposits on the consolidated balance sheets. Classification between deferred revenue and customer deposits depends on whether or not the Company has commenced performance of its performance obligations.

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, network charges, warranty and repair services, site costs and related expense associated with charging equipment as well as cost of sales related to the eXtend business and the sale of data services and other ancillary services. General and administrative expenses primarily consist of payroll and related personnel expenses, IT and office services, customer service, office rent expense and professional services.

Advertising Costs

Advertising costs are generally expensed as incurred and totaled $1.6 million and $2.0 million for the years ended December 31, 2023 and 2022, respectively.

Research and Development Costs

Research and development costs are expensed as incurred and totaled $5.7 million and $4.8 million for the years ended December 31, 2023 and 2022, 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 IRS annual limits. Employer contributions to the 401(k) plan for the years ended December 31, 2023 and 2022 were $0.3 million and $0.7 million, respectively.

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 (“ASC 718”), compensation expense for awards with service conditions is recorded over the requisite service period, and compensation expense for awards with market and service conditions is recognized over the longer of the explicit service period or the derived service period for the market condition for any awards that are expected to vest. The Company issues new shares upon the exercise of stock options and upon the vesting of restricted share units and performance stock units. The Company has elected to account for forfeitures as they occur.

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”). This method gives consideration to the future tax consequences associated with the differences between the financial accounting and tax basis of the assets and liabilities as well as the ultimate realization of any deferred tax asset resulting from such differences. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. When a valuation allowance is increased or decreased, a corresponding tax expense or benefit is recorded.

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

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 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

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

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, as if it had originated the contracts. The new standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASU 2021-08 prospectively on January 1, 2023. The adoption of this standard did not have any impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASC 326”). The amendments in ASC 326 provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a

reporting entity at each reporting date. Subsequent to the initial ASU, the FASB issued various related corrective and clarifying ASUs for this topic, all of which have been codified in ASC 326. For public companies that are considered “smaller reporting companies” as defined by the SEC, ASC 326 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASC 326 prospectively as of January 1, 2023. The adoption of this standard did not materially impact the Company’s consolidated results of operations or financial position.

Recently Issued Accounting Standards

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 (“ASU 2020-04”), as amended in December 2022 by ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 (“ASU 2022-06”). ASU 2020-04 provides 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, 2023, the Company has not identified any contracts, hedging relationships and other transactions impacted by reference rate reform and therefore does not expect any impact resulting from the adoption of ASU 2020-04 on the Company’s consolidated results of operations or financial position.

In November 2023, the FASB issued ASU 2023-07, ASC Subtopic 280 “Segment Reporting — Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 requires incremental disclosures related to a public entity’s reportable segments but does not change the definition of a segment, the method for determining segments, or the criteria for aggregating operating segments into reportable segments. ASU 2023-07 provides for significant segment expense categories and amounts for each reportable segment and an aggregate amount and description of other segment items included in each reported measure of segment profit or loss beyond the significant segment expenses for each reportable segment; permits the disclosure of multiple measures of segment profit or loss for each reportable segment, subject to a minimum disclosure of the measure of segment profit or loss that is most consistent with the amounts included in the financial statements (consistent with current guidance); confirms that all disclosures required in the segments guidance apply to all public entities, including those with a single operating or reportable segment; requires disclosure of the title and position of the individual or the name of the group identified as the CODM in the financial statements; and requires disclosure of how the CODM uses each reported measure of segment profit or loss to assess performance and allocate resources to the segment. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024 and should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB Issued ASU 2023-09, ASC Subtopic 740 “Income Taxes — Improvements to Income Tax Disclosures” (“ASU 2023-09”), which increases transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements.
