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, condensed consolidated statements of stockholders’ deficit and condensed consolidated statements of cash flows for the periods presented. The results of operations for the three months ended March 31, 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 57.6% of the Company’s total net accounts receivable as of March 31, 2023. The Company had one customer that comprised 20.5% of the Company’s total net accounts receivable as of December 31, 2022. For the three months ended March 31, 2023, two customers collectively represented 51.4% of revenue. For the three months ended March 31, 2022, two customers collectively represented 28.6% of revenue. For the three months ended March 31, 2023 and 2022, EVgo had one and four vendors, respectively, that provided more than 10% of EVgo’s total charging equipment. For each of the three months ended March 31, 2023 and 2022, the percentage of EVgo’s total charging equipment provided by these vendors collectively was 84.3%.
Reclassifications	Reclassifications The Company has made certain reclassifications to prior period amounts to conform to current period presentation.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and restricted cash include cash held in cash depository accounts in major banks in the U.S. and are stated at cost. Cash equivalents are carried at fair value and are primarily invested in money market funds. Cash that is held by a financial institution and has restrictions on its availability to the Company is classified as restricted cash. The Company had unused letters of credit, which were collateralized with cash, classified as restricted cash on the Company’s condensed consolidated balance sheets, of $0.7 million as of March 31, 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 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 $1.2 million and $1.3 million were included in accounts receivable, net, on the condensed consolidated balance sheets as of March 31, 2023 and December 31, 2022, respectively.
Newly Adopted Accounting Standards and Recently Issued Accounting Standards	Newly Adopted Accounting Standards In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), as if it had originated the contracts. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The adoption of the standard will impact future business combinations and require the Company to measure acquired contract assets and liabilities in accordance with ASC 606. The standard will not impact acquired contract assets or liabilities from business combinations occurring prior to the effective date of adoption. The Company adopted ASU 2021-08 prospectively on January 1, 2023. The adoption of this standard did not have any impact on the condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASC 326”). The amendments in ASC 326 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. Subsequent to the initial ASU, the FASB issued various related corrective and clarifying ASUs for this topic, all of which have been codified in ASC 326. For public companies that are considered “smaller reporting companies” as defined by the SEC, ASC 326 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASC 326 prospectively as of January 1, 2023. The adoption of this standard did not materially impact the Company’s condensed consolidated results of operations or financial position. Recently Issued Accounting Standards In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), as amended in December 2022 by ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 (“ASU 2022-06”). ASU 2020-04 provides guidance to alleviate the burden in accounting for reference rate reform by allowing certain expedients and exceptions in applying GAAP to contracts, hedging relationships and other transactions impacted by reference rate reform. The provisions apply only to those transactions that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. Adoption of the provisions of ASU 2020-04 are optional and are effective from March 12, 2020 through December 31, 2024, as amended by ASU 2022-06. As of March 31, 2023, the Company has not adopted any expedients and exceptions under ASU 2020-04. The Company will continue to evaluate the impact of ASU 2020-04 on its condensed consolidated financial statements.
