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” or the “Company”) 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 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. 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 is held by EVgo OpCo and continues 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”). On May 22, 2023, in connection with an underwritten equity offering, EVgo Member Holdings, an affiliate of EVgo Holdings, the Company’s controlling shareholder, purchased 5,882,352 shares of the Company’s Class A common stock at the equity offering price of $4.25 per share. 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. Accordingly, beginning on July 1, 2021 (the “CRIS Close Date”), the Company began consolidating 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 September 30, 2023, EVgo Holdings held 195,800,000 EVgo OpCo Units, representing 65.4% of the total outstanding EVgo OpCo Units and an equal number of shares of the Company’s Class B common stock. As of September 30, 2023, the shares of the Company’s Class B common stock held by EVgo Holdings and the shares of the Company’s Class A common stock held by EVgo Member Holdings collectively represented a 67.4% voting interest in the Company. 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”). ​ ​

The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the operating results for the full year ending December 31, 2023 or any other period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “Annual Report”). 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 condensed consolidated financial statements at the balance sheet date and/or required to be disclosed in the notes to the condensed consolidated financial statements. The Company has evaluated subsequent events accordingly. Use of Estimates The condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of EVgo’s condensed 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 and stand-alone selling prices for performance obligations for revenue, depreciable lives of property and equipment and intangible assets, costs associated with asset retirement obligations, the fair value of operating lease right-of-use assets and liabilities, reporting units used in goodwill impairment tests, 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 and believes it is not exposed to any significant credit risk on its cash balances. 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 41.5% of the Company’s total net accounts receivable as of September 30, 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 three and nine months ended September 30, 2023, one customer represented 29.6% and 49.3% of revenue, respectively. For the three months ended September 30, 2022, two customers collectively represented 23.3% of revenue. For the nine months ended September 30, 2022, one customer represented 17.2% of revenue. For the three months ended September 30, 2023, two vendors collectively provided 74.9% of EVgo’s total charging equipment. For the nine months ended September 30, 2023, one vendor provided 77.6% of EVgo’s total charging equipment. For the three months ended September 30, 2022, three vendors collectively provided 87.3% of EVgo’s total charging equipment. For the nine months ended September 30, 2022, three vendors collectively provided 78.6% 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 condensed consolidated balance sheets, of $0.7 million as of September 30, 2023 and December 31, 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 $1.5 million and $1.3 million were included in accounts receivable, net, on the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022, respectively.

Contract liabilities as of September 30, 2023 increased $19.2 million, or 33%, to $77.0 million compared to $57.8 million as of December 31, 2022. The balance of contract liabilities is driven by the difference in timing between when cash is received pursuant to a contract and when the Company’s performance obligations under the contract are satisfied. The following table presents the change in contract liabilities during the nine months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ Nine Months Ended (in thousands) ​ September 30, 2023 Balance as of December 31, 2022 ​ $ 57,790 Additions ​ 85,130 Recognized in revenue ​ ​ (65,645) Marketing activities recognized on a net basis ​ (289) Balance as of September 30, 2023 ​ $ 76,986 ​ Revenues related to contract liabilities for the three and nine months ended September 30, 2023 and 2022 included the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, September 30, (in thousands) ​ 2023 2022 2023 2022 Amounts included in the beginning of period contract liabilities balance ​ $ 9,305 ​ $ 849 ​ $ 15,865 ​ $ 3,438 Amounts associated with performance obligations satisfied in previous periods ​ $ 141 ​ $ — ​ $ 166 ​ $ 5 ​ It is anticipated that deferred revenue as of September 30, 2023 will be recognized in the following periods ending December 31: ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ 2023 ​ $ 4,017 2024 ​ 17,110 2025 ​ 14,353 2026 ​ 18,559 ​ ​ $ 54,039 ​ ASC 606 does not require disclosure of the transaction price to remaining performance obligations if the contract contains variable consideration allocated entirely to a wholly unsatisfied performance obligation. 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 obligation is not required. Under these contracts, variability arises as both volume and pricing are not known until the product is delivered. As of September 30, 2023 and December 31, 2022, there was $12.0 million and $8.7 million, respectively, in variable consideration for wholly unsatisfied performance obligations, which is included in deferred revenue on the condensed consolidated balance sheets.

LLC as sales agents, pursuant to which the Company may sell up to $200.0 million of shares of Class A common stock in “at the market” transactions at prevailing market prices (the “ATM Program”). In April 2023, EVgo sold 889,340 shares of Class A common stock pursuant to the ATM Program, with aggregate gross proceeds of $5.8 million. After deducting commissions of $0.1 million, the Company received net proceeds of approximately $5.7 million. Equity Offering During the three months ended June 30, 2023, the Company completed an underwritten equity offering of 30,123,129 shares of Class A common stock at an offering price of $4.25 per share with aggregate gross proceeds of $128.0 million. The Company received net proceeds of $123.4 million, after deducting $4.6 million in underwriting discounts and commissions and other offering costs. Issuance Costs In connection with the issuance of Class A common stock through the ATM Program and the equity offering, in addition to the discounts and commissions deducted from the gross proceeds, the Company incurred direct and incremental issuance costs, consisting primarily of legal, accounting, and other professional fees. Issuance costs directly attributable to the offering are recorded to additional paid-in capital as a reduction of proceeds. Deferred issuance costs will offset additional paid-in capital on a pro rata basis as the available shares on the shelf offering are issued. For the nine months ended September 30, 2023, $0.4 million of costs were recorded as additional paid-in capital as a reduction of proceeds. As of September 30, 2023 and December 31, 2022, $1.0 million of deferred issuance costs was included in other current assets.

Commitments and Contingencies
Commitments and Contingencies	Note 9 – 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 (the “Pilot Company”) and General Motors LLC (“GM”) to build, operate, and maintain up to 2,000 stalls served by DC chargers that the Pilot Company will own. The stalls will be located at the Pilot Company sites across the U.S. Pursuant to the Pilot Infrastructure Agreement, EVgo is required to meet certain construction milestones measured by the number of sites commissioned, and the 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, the 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 the 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 the Pilot Company elects to terminate the Pilot Infrastructure Agreement after 1,000 stalls have been completed, the 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 (as amended from time to time, the “GM Agreement”) to build fast charger stalls that EVgo will own and operate as part of the Company’s public network. The GM Agreement has been amended several times to expand the overall number of charger stalls to be installed from 2,750 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% across the GM network. 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, and delays associated with 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 EVgo executed an agreement with Nissan North America, Inc. (“Nissan”) in June 2019 (the “Nissan Agreement”), that provides for joint marketing activities, charging credit programs for purchasers or lessees of Nissan EVs, and a capital-build program. The Nissan 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 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 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 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 Agreement. EVgo and Nissan previously agreed to amend the Nissan 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, 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 has the right to terminate the Nissan Agreement, without penalty or obligation of any kind, upon 30 days’ written notice if it is unable to secure funding to make payments required under the Nissan Agreement. Nissan receives budget approvals annually from Nissan Motor Company Limited. Nissan has fulfilled its annual payment obligations under the Nissan Agreement. ​ 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 September 30, 2023, EVgo had $76.0 million in outstanding purchase order commitments to EVgo’s contract manufacturers and component suppliers for charging equipment, all of which were short-term. In certain instances, EVgo is permitted to cancel, reschedule or adjust these orders. As of September 30, 2023, EVgo had $14.7 million in other material commitments to third parties.

Fair Value Measurements
Fair Value Measurements	Note 10 – 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). 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 September 30, 2023 and December 31, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, ​ December 31, ​ ​ ​ 2023 ​ 2022 (in thousands) ​ ​ Level ​ Balance Level Balance Cash equivalents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ ​ 1 ​ $ 201,125 ​ 1 $ 150,125 Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Earnout liability 3 ​ $ 855 ​ 3 $ 1,730 Warrant liability – Public Warrants ​ ​ 1 ​ ​ 5,381 ​ 1 ​ 10,164 Warrant liability – Private Placement Warrants ​ ​ 3 ​ ​ 1,138 ​ 2 ​ 2,140 Total liabilities ​ ​ ​ ​ $ 7,374 ​ ​ $ 14,034 ​ The earnout liability was valued using a Monte Carlo simulation methodology.

The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the condensed consolidated statements of operations. The closing price of the Public Warrants was used as its fair value as of each relevant date. As of December 31, 2022, the Private Placement Warrants were measured by reference to the trading price of the Public Warrants, which is considered a Level 2 fair value measurement. As of March 31, 2023, the Private Placement Warrants were valued using the Monte Carlo simulation methodology, which is considered a Level 3 fair value measurement. Assumptions used in the valuation of the Private Placement Warrant liability using the Monte Carlo method simulation methodology are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ ​ ​ 2023 Stock price $ 7.79 Risk-free interest rate ​ ​ 3.78 % Expected term (in years) ​ ​ 3.3 ​ Expected volatility ​ ​ 33 % Dividend rate ​ ​ — % Exercise price ​ $ 11.50 ​ ​ As of June 30, 2023, the Private Placement Warrants were measured by reference to the trading price of the Public Warrants, which is considered a Level 2 fair value measurement. As of September 30, 2023, the Private Placement Warrants were valued using a Monte Carlo simulation methodology, which is considered a Level 3 fair value measurement. Assumptions used in the valuation of the Private Placement Warrant liability using the Monte Carlo simulation methodology are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, ​ ​ ​ 2023 Stock price ​ $ 3.38 Risk-free interest rate ​ ​ 4.86 % Expected term (in years) ​ ​ 2.8 ​ Expected volatility ​ ​ 71 % Dividend rate ​ ​ — % Exercise price ​ $ 11.50 ​ ​ 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 nine months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Private ​ ​ ​ ​ ​ Placement ​ ​ Earnout ​ Warrant (in thousands) ​ Liability ​ Liability Fair value as of December 31, 2022 ​ $ 1,730 ​ $ — Change in fair value of liability ​ ​ 2,063 ​ ​ — Transfers into Level 3 ​ ​ — ​ ​ 3,285 Fair value as of March 31, 2023 ​ ​ 3,793 ​ ​ 3,285 Change in fair value of liability ​ ​ (2,496) ​ ​ (1,320) Transfers out of Level 3 ​ ​ — ​ ​ (1,965) Fair value as of June 30, 2023 ​ ​ 1,297 ​ ​ — Change in fair value of liability ​ ​ (442) ​ ​ — Transfers into Level 3 ​ ​ — ​ ​ 1,138 Fair value as of September 30, 2023 ​ $ 855 ​ $ 1,138 ​ The carrying values of certain accounts such as cash, restricted cash, accounts receivable, 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 September 30, 2023 or December 31, 2022.

Income Taxes

Income Taxes
Income Taxes	Note 11 – Income Taxes The Company’s 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. The Company’s provision for income taxes and effective tax rates reflect the impact of a full valuation allowance on its deferred tax assets and a significant portion of income (loss) being allocated to a nontaxable partnership. 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. In assessing the realization of its 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 September 30, 2023 and December 31, 2022 . The Company files income tax returns in the U.S. at the federal level 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 September 30, 2023 and December 31, 2022, 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 12 – 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) (the “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. As of September 30, 2023, no transactions have 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. ​

Pursuant to the transition agreement, subject to certain conditions, Ms. Zoi shall be deemed to have remained in continuous employment with the Company or its affiliates through April 30, 2024, for purposes of vesting, settlement, and exercisability of her outstanding and unvested Company RSUs and stock options, and Ms. Zoi shall vest in her Time Vesting Incentive Units (as defined below) on January 16, 2024. Ms. Zoi will additionally vest in her Sale Vesting Incentive Units (as defined below) upon the consummation of a sale of the Company during the six month period following Ms. Zoi’s separation date, if such a sale transaction were to occur. The Company determined that these provisions represented a modification of the existing awards, resulting in the cumulative compensation cost recognized for the original RSU, stock option, and Time Vesting Incentive Unit awards being zero immediately prior to the modification as none of the awards were otherwise expected to vest. The incremental fair value of the modified RSU, stock option and Time Vesting Incentive Unit awards of $4.2 million will be recognized over the period from the modification date to the separation date. The incremental fair value of the modified Sale Vesting Incentive Unit awards was $6.1 million. The fair value of the modified awards is reflected in the weighted average grant date fair value of the Company’s unvested RSUs and Incentive Units (as defined below) as of September 30, 2023 in the tables below. ​ 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 September 30, 2023, there were 22,262,930 shares of Class A common stock available for grant.

No stock options were exercised during the nine months ended September 30, 2023. The fair values of stock options granted and modified during the three and nine months ended September 30, 2023 were computed using the Black-Scholes or the Hull-White option-pricing models, in order to ensure that the valuation reflected all substantive characteristics of the instruments, with the assumptions described below. For valuations where the Company had limited historical volatility information available, the expected volatility was based on a weighted average between the actual volatility for comparable public companies and the actual volatility for the Company, if shorter than the expected term of the options. The expected life under the Black-Scholes model was estimated using the simplified method. The expected life under the Black-Scholes model was estimated using the simplified method or full remaining term, based on whether or not the participant was expected to exercise the option. The expected life under the Hull-White model was calculated as the average time to achieve the 2.8x strike exercise price in the simulation. ​ ​ ​ ​ ​ ​ Risk-free interest rate ​ ​ 3.5 to 5.4 % Dividend yield ​ ​ — % Expected volatility ​ ​ 78 to 79 % Expected life (in years) ​ ​ 0.8 to 10.0 ​ ​ Restricted Stock Units The table below represents the Company’s RSU activity under the 2021 Incentive Plan during the nine months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ Average ​ ​ ​ Number of ​ Grant Date (shares in thousands) ​ ​ Shares Fair Value Unvested as of December 31, 2022 ​ ​ 3,930 ​ $ 10.85 Granted 1 ​ ​ 6,584 ​ $ 5.13 Vested ​ ​ (1,461) ​ $ 10.89 Forfeited ​ ​ (789) ​ $ 8.04 Unvested as of September 30, 2023 1 ​ ​ 8,264 ​ $ 6.55 ​ ​ ​ ​ ​ ​ ​ 1 Weighted average grant date fair value reflects the impact of modified awards ​ ​ ​ The total fair value of RSUs vested during the nine months ended September 30, 2023 was $8.2 million. As of September 30, 2023, the Company’s unrecognized share-based compensation expense related to unvested RSUs was approximately $29.4 million, which is expected to be recognized over a weighted average 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”). Of each individual grant of Incentive Units, 65% of the grant was designated as time vesting (the “Time Vesting Incentive Units”) and the remaining portion (35% of the grant) 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. Presented below is a summary of the activity of the Company’s Incentive Units during the nine months ended September 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ Grant Date (units in thousands) ​ Units Fair Value Unvested as of December 31, 2022 ​ ​ 471 ​ $ 18.68 Vested ​ ​ (108) ​ $ 17.24 Forfeited ​ ​ (81) ​ $ 34.97 Unvested as of September 30, 2023 1 ​ ​ 282 ​ $ 43.14 ​ ​ ​ ​ ​ ​ ​ 1 Weighted average grant date fair value reflects the impact of modified awards ​ As of September 30, 2023, the Company’s unrecognized share-based compensation expense related to unvested Time Vesting Incentive Units was approximately $2.4 million, which is expected to be recognized over a weighted average period of 0.5 years. As of September 30, 2023, unrecognized share-based compensation expense related to unvested Sale Vesting Incentive Units was approximately $8.0 million, which is contingent upon the occurrence of a sale event. The fair value of Incentive Units modified during the three and nine months ended September 30, 2023 were calculated using the Monte Carlo simulation model. Assumptions used in the valuation of the modified Incentive Units are as follows: ​ ​ ​ ​ ​ ​ Risk-free interest rate ​ ​ 4.5 % Discount for lack of marketability ​ ​ 10.0 % Expected volatility ​ ​ 76 % Time to exit (in years) ​ ​ 3.4 ​ ​

Redeemable Noncontrolling Interest
Redeemable Noncontrolling Interest	Note 15 – Redeemable Noncontrolling Interest As of September 30, 2023 and December 31, 2022, EVgo Holdings held 195,800,000 EVgo OpCo Units, representing a 65.6% and a 73.6% economic ownership interest, respectively, 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 that same number of shares of the Company’s Class B common stock, representing a 65.4% and a 73.4% voting interest, respectively, 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 following is a reconciliation of changes in redeemable noncontrolling interest for the nine months ended September 30, 2023: ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ Balance as of December 31, 2022 $ 875,226 Net loss attributable to redeemable noncontrolling interest (69,054) Equity-based compensation attributable to redeemable noncontrolling interest 1,843 Adjustment to revise redeemable noncontrolling interest to its redemption value at period-end (146,211) Balance as of September 30, 2023 $ 661,804 ​

Summary of Significant Accounting Policies
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are unaudited and are presented in accordance with GAAP for interim financial information, as set by the Financial Accounting Standards Board (“FASB”), and pursuant to the rules and regulations of the SEC. References to GAAP issued by the FASB in these notes to the condensed consolidated financial statements are to the FASB Accounting Standards Codification (“ASC”). The condensed consolidated financial statements include the accounts of the Company and its subsidiaries and all intercompany transactions have been eliminated in consolidation. These condensed consolidated financial statements include all adjustments considered necessary, in the opinion of management, for a fair presentation of the condensed consolidated balance sheets, condensed consolidated statements of operations and comprehensive income (loss), condensed consolidated statements of stockholders’ deficit and condensed consolidated statements of cash flows for the periods presented. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the operating results for the full year ending December 31, 2023 or any other period. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “Annual Report”). 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 condensed consolidated financial statements at the balance sheet date and/or required to be disclosed in the notes to the condensed consolidated financial statements. The Company has evaluated subsequent events accordingly.
Use of Estimates	Use of Estimates The condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of EVgo’s condensed 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 and stand-alone selling prices for performance obligations for revenue, depreciable lives of property and equipment and intangible assets, costs associated with asset retirement obligations, the fair value of operating lease right-of-use assets and liabilities, reporting units used in goodwill impairment tests, 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	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 its cash balances. 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 41.5% of the Company’s total net accounts receivable as of September 30, 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 three and nine months ended September 30, 2023, one customer represented 29.6% and 49.3% of revenue, respectively. For the three months ended September 30, 2022, two customers collectively represented 23.3% of revenue. For the nine months ended September 30, 2022, one customer represented 17.2% of revenue. For the three months ended September 30, 2023, two vendors collectively provided 74.9% of EVgo’s total charging equipment. For the nine months ended September 30, 2023, one vendor provided 77.6% of EVgo’s total charging equipment. For the three months ended September 30, 2022, three vendors collectively provided 87.3% of EVgo’s total charging equipment. For the nine months ended September 30, 2022, three vendors collectively provided 78.6% of EVgo’s total charging equipment.
Reclassifications	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, 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.

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 $1.5 million and $1.3 million were included in accounts receivable, net, on the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022, respectively.
