Description of Business and Nature of Operations
Description of Business and Nature of Operations	Note 1 – Description of Business and Nature of Operations EVgo owns and operates a public direct current (“DC”) fast charging network in the United States (“U.S.”). EVgo was founded in October 2010 as NRG EV Services, LLC, a Delaware corporation and wholly owned subsidiary of NRG Energy, Inc., an integrated power company based in Houston, Texas. EVgo’s network of charging stations provides EV charging infrastructure to consumers and businesses. Its network is capable of natively charging (i.e., charging without an adaptor) all EV models and charging standards currently available in the U.S. EVgo partners with national and regional chains of grocery stores, automotive OEMs, hotels, shopping centers, gas stations, parking lot operators, local governments and independent property owners in order to locate and deploy its EV charging infrastructure. COVID-19 Outbreak The global outbreak of COVID-19 has resulted in significant volatility in the global and domestic economies, changes in consumer and business behavior, market downturns and restrictions on business and individual activities, which has led to overall reduced economic activity. The COVID-19 pandemic also impacted the Company’s operations through construction delays and supply chain and shipping constraints. EVgo also experienced delays in its negotiations with commercial or public-entity property owners, landlords and/or tenants (collectively, the “Site Hosts”) as they devoted more time to day-to-day operations and employee health and safety. Finally, for some contractual commitments, EVgo is required to adhere to a construction schedule over specific timeframes. Those timelines were impacted due to delays associated with COVID-19, and it is possible that the ongoing pandemic could continue to impact these timelines in the future. How COVID-19 will affect EVgo’s future business results is unclear. While the disruption is expected to be temporary, there is considerable uncertainty around the duration and magnitude of this disruption. Development and commissioning lead times may be extended as a result of the measures taken by the state and local governments to mitigate the spread of COVID-19. The extent of the financial impact and duration cannot be reasonably estimated at this time.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Basis of Presentation and Consolidation The condensed consolidated financial statements are unaudited and prepared 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 unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries and all intercompany transactions have been eliminated in consolidation. These unaudited 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’ and member’s equity (deficit) and condensed consolidated statements of cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the operating results for the full year ending December 31, 2022 or any other period. These unaudited 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, 2021 (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. Reclassifications During the third quarter of 2021, the Company changed its presentation of certain costs, including network platform service fees, certain storage and freight costs, pre-operational rent/license fees, call center expenses and certain costs related to field and customer operations. In previous periods, these costs were included as a component of cost of sales. The Company now presents these costs as a component of general and administrative expenses. Management believes this presentation better reflects the nature of the costs, financial performance of the Company, enables better alignment between revenues and cost of sales and provides more clarity about the changes in cost of sales and general and administrative expenses, resulting in improved financial reporting and comparability and consistency of financial results. All periods presented have been retrospectively revised to reflect the effects of the change to cost of sales and general and administrative expenses. There was no net impact to loss from operations, net loss attributable to the Company or net loss per share for any periods presented. The condensed consolidated balance sheets, condensed consolidated statements of stockholders’ and member’s equity (deficit), and the condensed consolidated statements of cash flows are not affected by changes in the presentation of certain costs. ​ The following is a reconciliation for the respective periods: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ General and ​ ​ ​ ​ Administrative (in thousands) Cost of Sales Expenses For the three months ended June 30, 2022 ​ ​ Computed under previous method $ 11,582 $ 30,416 Change in presentation ​ (1,762) ​ 1,762 As adjusted ​ $ 9,820 ​ $ 32,178 ​ ​ ​ ​ ​ ​ ​ For the three months ended June 30, 2021 ​ ​ As previously reported $ 7,548 $ 12,247 Change in presentation ​ (1,091) ​ 1,091 As adjusted ​ $ 6,457 ​ $ 13,338 ​ ​ ​ ​ ​ ​ ​ For the six months ended June 30, 2022 ​ ​ Computed under previous method $ 21,617 $ 54,109 Change in presentation ​ (3,497) ​ 3,497 As adjusted ​ $ 18,120 ​ $ 57,606 ​ ​ ​ ​ ​ ​ ​ For the six months ended June 30, 2021 ​ ​ ​ ​ As previously reported $ 14,288 $ 23,321 Change in presentation ​ (2,023) ​ 2,023 As adjusted ​ $ 12,265 ​ $ 25,344 ​ The Company has also made certain other reclassifications to prior period amounts to conform to the current period presentation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates made by management include, but are not limited to, charging station depreciable lives, costs associated with asset retirement obligations, the fair value of the share-based compensation, earnout liability, warrant liability and the fair value measurements of assets and liabilities allocated for acquired businesses. Accordingly, the actual results could differ significantly from those estimates. ​ Concentration of Business and Credit Risk The Company maintains its cash accounts in a commercial bank. The total cash balances held in a commercial bank are secured by the Federal Deposit Insurance Corporation up to $250,000. At various times throughout the period, the Company had uninsured balances. The Company has not experienced any losses on such accounts and believes it is not exposed to any significant credit risk on cash. The Company mitigates its risk with respect to cash by maintaining its deposits at high-quality financial institutions and monitoring the credit ratings of those institutions. The Company had three customers that comprised 44.4% of the Company’s total accounts receivable as of June 30, 2022. The Company had two customers that comprised 32.4% of the Company’s total accounts receivable as of December 31, 2021. For the six months ended June 30, 2022 and 2021, two customers represented 31.9% and one customer represented 15.0% of total revenue, respectively. For the six months ended June 30, 2022 EVgo had four vendors that provided 84.8% of total charging equipment and services to the Company. For the six months ended June 30, 2021, EVgo had three vendors that provided 71.8% of total charging equipment and services to the Company. Cash, Restricted Cash and Cash Equivalents Cash, restricted cash and cash equivalents include cash held in cash depository accounts in major banks in the U.S. and are stated at cost. EVgo considers all highly liquid instruments with original maturities of three months or less at the time of purchase to be cash equivalents. The Company holds $4.4 million of investments that are considered cash equivalents as of June 30, 2022. Cash that is held by a major bank and has restrictions on its availability to the Company is classified as restricted cash. The Company had unused letters of credit of $0.7 million, as of June 30, 2022 and December 31, 2021, associated with the construction of its charging stations and in connection with one of its operating leases. Cash balances collateralizing these letters of credit are considered restricted cash. 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. Investments Available-for-sale Debt Securities The Company’s short-term and long-term investments consist primarily of investment-grade debt securities, all of which are classified as available-for-sale. Available-for-sale debt securities are recorded at fair value, and unrealized gains and losses that are considered to be temporary are recorded, net of tax, as a component of accumulated other comprehensive income. EVgo considers all highly liquid interest-earning investments with a maturity of three months or less at the date of purchase to be cash equivalents. In general, investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. All other investments are classified as long-term. The Company evaluates the available-for-sale securities for other-than-temporary impairment on a quarterly basis. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary. The Company reviews several factors to determine whether a loss is other than temporary, such as the length and extent of the fair value decline, the financial condition and near-term prospects of the issuer and whether the Company has the intent to sell or will more likely than not be required to sell the securities before the securities' anticipated recovery, which may be at maturity. Realized gains and losses are accounted for using the specific identification method. Purchases and sales of securities are recorded on a trade-date basis. EVgo’s investment portfolio primarily includes corporate debt securities, asset backed securities, U.S. government treasury securities, certificates of deposit and commercial paper.

Lease Accounting
Lease Accounting	Note 5 – Lease Accounting As disclosed in Note 2, the Company adopted ASC 842 as of January 1, 2022. 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 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 right-of-use asset and 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 right-of-use 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, a percentage of annual sales volume, periodic adjustments related to inflation or a combination of such lease payments. In addition to minimum lease payments, the Company’s lease agreements may contain variable lease payments based on revenue sharing or inflation adjustments. The Company has elected the practical expedient to not separate non-lease components from lease components in the measurement of liabilities for all asset classes. Lease liabilities are recognized at the present value of the fixed lease payments using an implicit rate and, if not available, an incremental borrowing rate based on estimated collateralized borrowings available to the Company. The Company incurs initial direct costs and receives landlord incentives that increase or decrease the calculated right-of-use asset, respectively. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company expenses variable lease payments as incurred. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company has not entered into any finance leases. ​ As a lessor, the Company has entered into agreements to lease charging equipment, charging stations and other technical installations or sublease properties leased from Site Hosts to third parties. The Company, at the inception of a lease contract, determines if it is an operating, sales-type or direct financing lease. The leases 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 condensed consolidated statements of operations and comprehensive income (loss). Lessee Accounting The Company has entered into agreements with Site Hosts, which allow the Company to operate the charging stations on the Site Hosts’ property. Additionally, the Company leases offices and laboratory space under agreements with third-party landlords. The agreements with the Site Hosts and landlords are deemed to be operating leases and contain terms ranging from one one The Company has estimated operating lease commitments of $56.5 million for leases where the Company has not yet taken possession of the underlying asset as of June 30, 2022. As such, the related operating lease right-of-use assets and operating lease liabilities have not been recognized in the Company’s condensed consolidated balance sheet as of June 30, 2022. For the three and six months ended June 30, 2022, the Company’s lease costs consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three ​ Six ​ ​ Months Ended ​ Months Ended ​ ​ June 30, ​ June 30, (in thousands) ​ 2022 ​ 2022 Operating lease costs 1 ​ ​ ​ ​ ​ ​ Cost of sales ​ $ 730 ​ $ 1,091 Selling, general and administrative expenses ​ ​ 607 ​ ​ 1,280 Variable lease costs ​ ​ ​ ​ ​ ​ Cost of sales ​ ​ 97 ​ ​ 187 Selling, general and administrative expenses ​ ​ 15 ​ ​ 36 Short-term lease costs ​ ​ 32 ​ ​ 44 ​ ​ $ 1,481 ​ $ 2,638 1 As of June 30, 2022, the maturities of operating lease liabilities for the years ending December 31, are as follows: ​ ​ ​ ​ ​ (in thousands) ​ ​ 2022 ​ $ 2,786 2023 ​ ​ 6,361 2024 ​ ​ 5,746 2025 ​ ​ 4,849 2026 ​ ​ 4,430 2027 ​ ​ 3,755 Thereafter ​ ​ 14,616 Total undiscounted operating lease payments ​ ​ 42,543 Less: imputed interest ​ ​ (9,775) Total discounted operating lease liabilities ​ $ 32,768 ​ The following table shows future minimum payments under noncancellable operating leases with initial terms of greater than one year, based on the expected due dates of the various installments as of December 31, 2021, as previously reported in the Company’s Annual Report, prior to the adoption of ASC 842: ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ 2022 ​ $ 3,486 2023 ​ ​ 3,515 2024 ​ ​ 2,987 2025 ​ ​ 2,093 2026 ​ ​ 1,767 Thereafter ​ ​ 5,570 ​ ​ $ 19,418 ​ Other supplemental information, as of June 30, 2022, consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ 2022 Weighted-average remaining lease term ​ 8.0 years ​ Weighted-average discount rate ​ ​ 6.41 % ​ ​ Other supplemental cash flow information, for the six months ended June 30, 2022, consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ Six ​ ​ ​ Months Ended ​ ​ ​ June 30, ​ (in thousands) ​ 2022 ​ Cash paid for amounts included in measurement of operating lease liabilities ​ $ 2,378 ​ Right-of-use assets obtained in exchange for new operating lease liabilities ​ $ 15,651 ​ ​ Lessor Accounting The Company leases charging equipment, charging stations and other technical installations and subleases properties leased from Site Hosts to third parties under operating leases where EVgo is the lessor.

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 (“Pilot Company”) and General Motors LLC (“GM”) to build, operate, and maintain up to 2,000 stalls served by DC chargers that Pilot Company will own. The stalls will be located at approximately 500 Pilot Company sites across more than 40 states. ​ Pursuant to the Pilot Infrastructure Agreement, EVgo is required to meet certain construction milestones measured by the number of sites commissioned, and Pilot Company is required to make certain payments each month based on completion of pre-engineering and development work, the progress of construction at each site and for each charger procured by EVgo. Subject to extensions of time for specified excusable events, if EVgo is unable to meet its commissioning obligations, Pilot Company will be entitled to liquidated damages calculated per day, subject to a cap of $30,000 at each site. The Pilot Infrastructure Agreement contains various provisions that may permit or cause early termination, including Pilot’s right to terminate after 1,000 stalls have been completed, the inability of EVgo to secure certain chargers and a material increase in the price of chargers due to a change in law. If Pilot Company elects to terminate the Pilot Infrastructure Agreement after 1,000 stalls have been completed, Pilot Company must pay EVgo a termination fee per stall for those not built; such fee varies based on the number of stalls already built. If EVgo is wholly or partially unable to perform its obligations under the Pilot Infrastructure Agreement due to certain circumstances outside its control, including delays by permitting authorities and utilities or certain force majeure events, such inability will not be considered a breach or default under the Pilot Infrastructure Agreement. ​ Under the Pilot O&M, EVgo is required to perform operations, maintenance and networking services on stalls built and commissioned under the Pilot Infrastructure Agreement in exchange for payment of a monthly fee by Pilot to EVgo. EVgo is subject to certain performance criteria under the Pilot O&M. ​ Delta Charger Supply Agreement and Purchase Order On July 12, 2022, EVgo entered into a General Terms and Conditions for Sale of EV Charger Products (the “Delta Charger Supply Agreement”) with Delta Electronics, Inc. (“Delta”), including an initial purchase order (the “Purchase Order”), pursuant to which EVgo will purchase and Delta will sell EV chargers manufactured by Delta in specified quantities at certain delivery dates. EVgo expects to use a portion of the chargers purchased under the Purchase Order to meet the requirements of the Pilot Infrastructure Agreement. EVgo is required to purchase a minimum of 1,000 chargers (which will enable the construction of 2,000 stalls) from Delta under the Purchase Order and may at EVgo’s election, increase the number of chargers it purchases from Delta to 1,100. Nissan Agreements EVgo has executed two program services agreements with Nissan North America, Inc. (“Nissan”). Under the terms of the Nissan Agreement, purchasers or lessees of Nissan LEAF EVs in certain markets could receive charging services at an EVgo station or a participating third-party charging station. Pursuant to the Nissan Agreement, the Company was required to support, maintain and make available at least 850 chargers through July 7, 2021. The Company fulfilled all build, support and maintenance obligations under the Nissan Agreement. On June 13, 2019, EVgo entered into a second agreement with Nissan (the “Nissan 2.0 Agreement”). The Nissan 2.0 Agreement includes a capital-build program requiring 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”). Under the terms of the Nissan 2.0 Agreement, the Build Schedule is negotiated at the beginning of each year. In 2021, EVgo worked with Nissan to revise the annual Build Schedule to extend the milestone dates. All chargers for each program year must be installed by November 30. Furthermore, Nissan waived penalties for installation delays in program year one. EVgo’s ability to meet Build Schedule obligations may be impacted by delays in permitting, slower than expected third-party approvals of certain site acquisitions, delays in utility interconnection resulting from industry adaptation to the requirements of high-powered charger installation, as well as supply chain issues. Going forward, EVgo is uncertain if these, or other potential issues in the procurement, installation, or energization of DCFC, will be resolved in a timely fashion. At this time, EVgo’s ability to meet future Build Schedule obligations may continue to be impacted by circumstances similar to those experienced during the first half of 2021, or other potential issues including, but not limited to, equipment design and procurement, timing of third-party funding agreements, and the siting, permitting, construction, energizing of DCFC or delays in releasing public grant funding. 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. Nissan has the right to terminate the Nissan 2.0 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 2.0 Agreement. Nissan receives budget approvals annually from Nissan Motor Company Limited. As of June 30, 2022, Nissan has fulfilled its annual payment obligations under the Nissan 2.0 Agreement. If Nissan terminates the Nissan 2.0 Agreement due to a lack of funding, EVgo will still be required to perform the following: (i) meet charger installation milestones through the date of termination; (ii) provide an aggregate of $1.6 million in joint marketing activities and (iii) provide $4.8 million worth of charging credits that shall continue to be administered. Pursuant to the Nissan 2.0 Agreement, as modified by the aforementioned extension and other amendments, EVgo is required to install an aggregate of 210 chargers by February 29, 2024 at a number of sites to be mutually agreed upon during each Build Schedule. Pursuant to the current Build Schedule, EVgo is required to install 58 chargers by November 30, 2022. If the Company fails to meet future Build Schedule obligations, Nissan may invoke a penalty of up to $70,000 per delayed site beyond a designated cure period, up to 52 sites, which would result in an adjustment to the consideration received for the Company’s performance obligations under the Nissan 2.0 Agreement. General Motors Agreement On July 20, 2020, EVgo entered into a five-year contract (the “GM Agreement”) with GM to build 2,750 fast chargers that EVgo will own and operate as part of the Company’s public network. On November 2, 2021, EVgo entered into an amendment agreement with GM in order to adjust stall installation targets and expand the overall number of chargers to be installed to 3,250 fast chargers. EVgo believes this agreement will serve to accelerate the Company’s development plans and enhance customer acquisition and brand equity among retail drivers. 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 chargers installed. Under the GM Agreement, EVgo is required to install a total of 3,250 chargers by December 31, 2025, 72% 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, commission or aspects of installation of the chargers 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 93%. In addition to the capital build program, EVgo committed to providing a certain number of new GM EV cars with an EVgo charging credit and limited time access to other EVgo services at a discounted rate. The GM Agreement is subject to early termination in certain circumstances, including in the event EVgo fails to meet the quarterly charger-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-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. As of June 30, 2022, there were approximately 2,615 stalls that had been approved by GM, of which approximately 3,100 stalls were already in the active engineering and construction development pipeline. As of June 30, 2022, EVgo had 221 stalls left to install in order to meet its charger-installation milestone. EVgo is required to open to the public 428 additional stalls by September 30, 2022 or GM will have the right, if it so chooses, to send EVgo a stall count breach notice, which would trigger a cure period through December 31, 2022. EVgo may not meet the charger-installation milestones under the GM Agreement in the future, particularly as a consequence of delays in permitting, commissioning and utility interconnection resulting from COVID-19 and supply chain disruptions in business operations across the utility, engineering and permitting chain, as well as industry and regulatory adaptation to the requirements of high-powered charger installation, including slower than expected third-party approvals between utilities and landowners of sites where charger stations will be located. 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 or employment, health and safety matters. Although the outcome of any potential future litigation is uncertain, the Company believes it has adequate insurance coverage in the event of any future litigation or disputes. Although the Company is not currently facing any material pending or threatened litigation, future events or circumstances, currently unknown to management, may potentially have a material effect on its financial position, liquidity or results of operations in any future reporting period.

Fair Value Measurements
Fair Value Measurements	Note 11 – 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 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 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 June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Adjusted ​ Unrealized ​ Unrealized ​ Fair (in thousands) ​ ​ Level ​ Cost Basis ​ Gains ​ Losses ​ Value Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial paper ​ ​ 2 ​ $ 3,112 ​ $ — ​ $ — ​ $ 3,112 Corporate debt securities ​ ​ 2 ​ ​ 1,258 ​ ​ — ​ ​ — ​ ​ 1,258 Total cash equivalents ​ ​ ​ ​ ​ 4,370 ​ ​ — ​ ​ — ​ ​ 4,370 Short-term investments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificates of deposit ​ ​ 2 ​ ​ 3,279 ​ ​ — ​ ​ (20) ​ ​ 3,259 Commercial paper ​ ​ 2 ​ ​ 1,611 ​ ​ — ​ ​ — ​ ​ 1,611 U.S. government treasury securities ​ ​ 2 ​ ​ 5,999 ​ ​ — ​ ​ (32) ​ ​ 5,967 Corporate debt securities ​ ​ 2 ​ ​ 17,026 ​ ​ 1 ​ ​ (88) ​ ​ 16,939 Total short-term investments ​ ​ ​ ​ ​ 27,915 ​ ​ 1 ​ ​ (140) ​ ​ 27,776 Long-term investments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Corporate debt securities ​ ​ 2 ​ ​ 5,265 ​ ​ — ​ ​ (35) ​ ​ 5,230 Asset-backed securities ​ ​ 2 ​ ​ 1,575 ​ ​ — ​ ​ (8) ​ ​ 1,567 Total long-term investments ​ ​ ​ ​ ​ 6,840 ​ ​ — ​ ​ (43) ​ ​ 6,797 Total ​ ​ ​ ​ $ 39,125 ​ $ 1 ​ $ (183) ​ $ 38,943 ​ The following table presents the fair value and net carrying amount of debt securities by contractual maturity as of June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Adjusted ​ Fair (in thousands) ​ Cost Basis ​ Value Due within one year ​ $ 32,285 ​ $ 32,146 Due after one year through five years ​ ​ 6,840 ​ ​ 6,797 Total ​ $ 39,125 ​ $ 38,943 ​ The Company’s available-for-sale debt securities are valued using the representative “bid” quotation for long positions and “ask” quotation for short positions from independent, third-party pricing services. These prices are generally based on bid/ask data from exchanges or trading systems, recent transactions from exchanges or trading systems, or quotes from market makers and dealers. This is categorized as Level 2 in the fair value hierarchy. The following table presents information about the Company’s 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 June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, (in thousands) ​ ​ Level ​ 2022 Earnout liability 3 ​ ​ $ 2,584 Warrant liability – Public Warrants ​ ​ 1 ​ ​ $ 18,686 Warrant liability – Private Placement Warrants ​ ​ 2 ​ ​ $ 3,935 ​ The earnout liability was valued using a Monte Carlo simulation methodology. The warrants are accounted for as liabilities in accordance with ASC 815 and are presented as warrant liabilities on the condensed consolidated balance sheets. 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 liability in the condensed consolidated statements of operations and comprehensive income (loss). The close price of the Public Warrants was used as the fair value as of each reporting date. As of June 30, 2022 other transfers between 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 six months ended June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Private ​ ​ ​ ​ ​ ​ Placement ​ ​ ​ ​ ​ ​ Warrant ​ ​ Earnout (in thousands) ​ Liability ​ ​ Liability Fair value as of December 31, 2021 ​ $ 8,847 ​ ​ $ 5,211 Change in fair value of liability ​ ​ (4,912) ​ ​ ​ (2,627) Transfers out of Level 3 ​ ​ (3,935) ​ ​ ​ — Fair value as of June 30, 2022 ​ $ — ​ ​ $ 2,584 ​ ​ ​ ​ ​ ​ ​ ​ Net change in unrealized gain (loss) for investments still held at June 30, 2022 ​ $ — ​ ​ $ (2,627) ​ The fair value of the Private Placement Warrants issued was initially measured using a Monte Carlo simulation model. The fair value of the Private Placement Warrants was measured as of June 30, 2022 by reference to the trading price of the Public Warrants, which is considered to be a Level 2 fair value measurement. ​ Earnout Liability The estimated fair value of the 1,437,500 shares of Class A common stock held by the Company’s initial stockholders that are subject to potential forfeiture (the “Earnout Shares”) issued and outstanding at the closing of the CRIS Business Combination on the CRIS Close Date was $18.3 million based on a Monte Carlo simulation valuation model using a distribution of potential outcomes on a monthly basis over the earnout period between the CRIS Close Date and the five-year anniversary of the CRIS Close Date using the most reliable information available. On July 2, 2021, the volume-weighted average price (“VWAP”) of shares of Class A common stock equaled or exceeded $12.50 for 20 trading days within a 30-trading day period within five years of the CRIS Close Date and, as a result, 718,750 Earnout Shares valued at $10.9 million were deemed to be earned and reclassified into equity on that date. The estimated fair value of the earnout liability related to the 718,750 Earnout Shares subject to a VWAP of $15.00 (the “$15.00 Triggering Event”) originally valued at $8.8 million was remeasured to $5.2 million as of December 31, 2021 and to $2.6 million as of June 30, 2022.

Income Taxes

Income Taxes
Income Taxes	Note 12 – Income Taxes The Company’s provision for income taxes consists primarily of income taxes, in federal and state jurisdictions where EVgo OpCo and its subsidiaries conduct business, that are incurred by the Company as a result of the Company’s ownership interest in EVgo OpCo. For the three and six months ended June 30, 2022 and 2021, the Company’s provision for income taxes and effective tax rate were deemed to be de minimis. Prior to July 1, 2021, EVgo Holdco and its subsidiaries were not taxable entities for U.S. federal income tax purposes or for any of the states in which such entities operated. On July 1, 2021, pursuant to the CRIS Business Combination, the Company acquired an interest in EVgo Holdco and its subsidiaries through EVgo OpCo, and the Company’s allocable share of EVgo OpCo’s income became subject to U.S. federal and state income taxes in jurisdictions in which EVgo OpCo and its subsidiaries operate. ​ 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 maintained a full valuation allowance against its net deferred tax assets as of June 30, 2022 and December 31, 2021 . ​ In addition, there were no unrecognized tax benefits for uncertain tax positions, nor any amounts accrued for interest and penalties as of June 30, 2022 or December 31, 2021.

Tax Receivable Agreement
Tax Receivable Agreement	Note 13 – Tax Receivable Agreement In connection with the CRIS Business Combination, EVgo entered into 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 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 Group 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 June 30, 2022 and December 31, 2021, 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.

In connection with the CRIS Business Combination, EVgo Holdings contributed all of the equity interests in EVgo Holdco to EVgo OpCo in exchange for 195,800,000 EVgo OpCo Units, the Company contributed all of its assets and 195,800,000 shares of Class B common stock to Thunder Sub, Thunder Sub transferred 195,800,000 shares of Class B common stock and the right to enter into the Tax Receivable Agreement to EVgo Holdings, and Thunder Sub contributed all of its remaining assets to EVgo OpCo in exchange for EVgo OpCo Units equal to the number of shares of Class A common stock outstanding. The shares of Class B common stock owned by EVgo Holdings have been evaluated and are excluded from net income or loss per share calculations as they do not participate in earnings or loss of the Company. Therefore, retrospective application of the conversion of these ownership interests into shares of Class B common stock would not result in an appropriate or meaningful presentation of earnings (loss) per common share (“EPS”). Therefore, the EPS information presented only relates to the periods subsequent to the consummation of the CRIS Business Combination on July 1, 2021 and has not been presented for the three and six months ended June 30, 2021. ​ The Company’s potentially dilutive securities consist of the Company’s Public Warrants, Private Placement Warrants, restricted stock units (“RSUs”), stock options and unvested Earnout Shares. For the periods in which EPS is presented, the Company excluded the following potential shares, presented based on amounts outstanding at each period end, from the computation of diluted net income (loss) per share attributable to Class A common stockholders since their impact would have been antidilutive: ​ ​ ​ ​ ​ ​ ​ ​ Three ​ Six ​ ​ Months Ended ​ Months Ended (in thousands) ​ June 30, 2022 ​ June 30, 2022 Public Warrants ​ 14,949 ​ 14,949 Private Placement Warrants ​ 3,149 ​ 3,149 RSUs ​ 1,907 ​ 3,343 Stock options ​ 375 ​ 375 ​ ​ 20,380 ​ 21,816 ​ Additionally, 718,750 unvested Earnout Shares (participating securities) were excluded from the computation of diluted EPS since their vesting threshold (i.e., the $15.00 Triggering Event) had not been met as of June 30, 2022.

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 June 30, 2022, there were 29,767,792 shares of Class A common stock available for grant. The 2021 Incentive Plan provides for potential grants of: (i) incentive stock options qualified as such under U.S. Federal income tax laws; (ii) stock options that do not qualify as incentive stock options; (iii) stock appreciation rights; (iv) restricted stock awards; (v) RSUs; (vi) vested stock awards; (vii) dividend equivalents; (viii) other share- or cash-based awards; (ix) cash awards; and (x) substitute awards.

Redeemable Noncontrolling Interest
Redeemable Noncontrolling Interest	Note 16 – Redeemable Noncontrolling Interest As of June 30, 2022, EVgo Holdings owns 195,800,000 EVgo OpCo Units, representing a 73.9% economic ownership interest in EVgo OpCo, and a corresponding number of shares of Class B common stock, representing a 73.9% voting interest in the Company. EVgo Holdings is entitled to one vote per share of Class B common stock but is not entitled to receive dividends or any assets upon liquidation, dissolution, distribution or winding-up of the Company. Each EVgo OpCo Unit is redeemable, together with one share of Class B common stock, for either one share of Class A common stock or, at EVgo OpCo’s election, the cash equivalent market value of one share of Class A common stock in accordance with the terms of the EVgo OpCo A&R LLC Agreement. 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 or loss. The table below presents the reconciliation of changes in redeemable noncontrolling interest for the six months ended June 30, 2022: ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ Balance as of December 31, 2021 $ 1,946,252 Net income attributable to redeemable noncontrolling interest for the period (28,349) Equity-based compensation attributable to redeemable noncontrolling interest during the period 968 Net unrealized loss on available-for-sale securities attributable to redeemable noncontrolling interest during the period ​ ​ (135) Adjustment to revise redeemable noncontrolling interest to its redemption value at period-end (741,978) Balance as of June 30, 2022 $ 1,176,758 ​

Summary of Significant Accounting Policies
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The condensed consolidated financial statements are unaudited and prepared 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 unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries and all intercompany transactions have been eliminated in consolidation. These unaudited 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’ and member’s equity (deficit) and condensed consolidated statements of cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the operating results for the full year ending December 31, 2022 or any other period. These unaudited 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, 2021 (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.
Reclassifications	Reclassifications During the third quarter of 2021, the Company changed its presentation of certain costs, including network platform service fees, certain storage and freight costs, pre-operational rent/license fees, call center expenses and certain costs related to field and customer operations. In previous periods, these costs were included as a component of cost of sales. The Company now presents these costs as a component of general and administrative expenses. Management believes this presentation better reflects the nature of the costs, financial performance of the Company, enables better alignment between revenues and cost of sales and provides more clarity about the changes in cost of sales and general and administrative expenses, resulting in improved financial reporting and comparability and consistency of financial results. All periods presented have been retrospectively revised to reflect the effects of the change to cost of sales and general and administrative expenses. There was no net impact to loss from operations, net loss attributable to the Company or net loss per share for any periods presented. The condensed consolidated balance sheets, condensed consolidated statements of stockholders’ and member’s equity (deficit), and the condensed consolidated statements of cash flows are not affected by changes in the presentation of certain costs. ​ The following is a reconciliation for the respective periods: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ General and ​ ​ ​ ​ Administrative (in thousands) Cost of Sales Expenses For the three months ended June 30, 2022 ​ ​ Computed under previous method $ 11,582 $ 30,416 Change in presentation ​ (1,762) ​ 1,762 As adjusted ​ $ 9,820 ​ $ 32,178 ​ ​ ​ ​ ​ ​ ​ For the three months ended June 30, 2021 ​ ​ As previously reported $ 7,548 $ 12,247 Change in presentation ​ (1,091) ​ 1,091 As adjusted ​ $ 6,457 ​ $ 13,338 ​ ​ ​ ​ ​ ​ ​ For the six months ended June 30, 2022 ​ ​ Computed under previous method $ 21,617 $ 54,109 Change in presentation ​ (3,497) ​ 3,497 As adjusted ​ $ 18,120 ​ $ 57,606 ​ ​ ​ ​ ​ ​ ​ For the six months ended June 30, 2021 ​ ​ ​ ​ As previously reported $ 14,288 $ 23,321 Change in presentation ​ (2,023) ​ 2,023 As adjusted ​ $ 12,265 ​ $ 25,344 ​ The Company has also made certain other reclassifications to prior period amounts to conform to the current period presentation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates made by management include, but are not limited to, charging station depreciable lives, costs associated with asset retirement obligations, the fair value of the share-based compensation, earnout liability, warrant liability and the fair value measurements of assets and liabilities allocated for acquired businesses. Accordingly, the actual results could differ significantly from those estimates.
Concentration of Business and Credit Risk	Concentration of Business and Credit Risk The Company maintains its cash accounts in a commercial bank. The total cash balances held in a commercial bank are secured by the Federal Deposit Insurance Corporation up to $250,000. At various times throughout the period, the Company had uninsured balances. The Company has not experienced any losses on such accounts and believes it is not exposed to any significant credit risk on cash. The Company mitigates its risk with respect to cash by maintaining its deposits at high-quality financial institutions and monitoring the credit ratings of those institutions. The Company had three customers that comprised 44.4% of the Company’s total accounts receivable as of June 30, 2022. The Company had two customers that comprised 32.4% of the Company’s total accounts receivable as of December 31, 2021. For the six months ended June 30, 2022 and 2021, two customers represented 31.9% and one customer represented 15.0% of total revenue, respectively. For the six months ended June 30, 2022 EVgo had four vendors that provided 84.8% of total charging equipment and services to the Company. For the six months ended June 30, 2021, EVgo had three vendors that provided 71.8% of total charging equipment and services to the Company.
Cash, Restricted Cash and Cash Equivalents	Cash, Restricted Cash and Cash Equivalents Cash, restricted cash and cash equivalents include cash held in cash depository accounts in major banks in the U.S. and are stated at cost. EVgo considers all highly liquid instruments with original maturities of three months or less at the time of purchase to be cash equivalents. The Company holds $4.4 million of investments that are considered cash equivalents as of June 30, 2022. Cash that is held by a major bank and has restrictions on its availability to the Company is classified as restricted cash. The Company had unused letters of credit of $0.7 million, as of June 30, 2022 and December 31, 2021, associated with the construction of its charging stations and in connection with one of its operating leases. Cash balances collateralizing these letters of credit are considered restricted cash.
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.
Investments Available-for-sale Debt Securities	Investments Available-for-sale Debt Securities The Company’s short-term and long-term investments consist primarily of investment-grade debt securities, all of which are classified as available-for-sale. Available-for-sale debt securities are recorded at fair value, and unrealized gains and losses that are considered to be temporary are recorded, net of tax, as a component of accumulated other comprehensive income. EVgo considers all highly liquid interest-earning investments with a maturity of three months or less at the date of purchase to be cash equivalents. In general, investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. All other investments are classified as long-term. The Company evaluates the available-for-sale securities for other-than-temporary impairment on a quarterly basis. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary. The Company reviews several factors to determine whether a loss is other than temporary, such as the length and extent of the fair value decline, the financial condition and near-term prospects of the issuer and whether the Company has the intent to sell or will more likely than not be required to sell the securities before the securities' anticipated recovery, which may be at maturity. Realized gains and losses are accounted for using the specific identification method. Purchases and sales of securities are recorded on a trade-date basis. EVgo’s investment portfolio primarily includes corporate debt securities, asset backed securities, U.S. government treasury securities, certificates of deposit and commercial paper.
