Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as "estimate," "plan," "project," "forecast," "intend," "will," "expect," "anticipate," "believe," "seek," "target," "assume" or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements are based on current expectations or beliefs of the management of EVgo Inc. (“EVgo” or the “Company”) and are subject to numerous assumptions, risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. These forward-looking statements include, but are not limited to, express or implied statements regarding EVgo’s future financial and operating performance, revenues, capital expenditures, chargers in operation or under construction and network throughput; EVgo’s expectation of market position and acceleration in its business due to factors including increased EV adoption; EVgo’s collaboration with partners enabling effective deployment of chargers, including under its contract with Pilot Flying J and GM; and anticipated awards of funding in connection with the NEVI program and associated state programs. These statements are based on various assumptions, whether or not identified in this presentation, and on the current expectations of EVgo’s management and are not predictions of actual performance. There are a significant number of factors that could cause actual results to differ materially from the statements made in this presentation, including changes or developments in the broader general market; macro political, economic, and business conditions, including inflation and geopolitical conflicts that could impact EVgo’s supply chains; increased competition, including from new and existing entrants in the EV charging market; unfavorable conditions or further disruptions in the capital and credit markets and EVgo's ability to obtain additional capital on commercially reasonable terms; EVgo’s limited operating history as a public company; EVgo’s dependence on widespread adoption of EVs and increased installation of charging stations; mechanisms surrounding energy and non-energy costs for EVgo’s charging stations; the impact of governmental support and mandates that could reduce, modify, or eliminate financial incentives, rebates, tax credits, and other support available to EVgo; supply chain disruptions; EVgo’s ability to expand into new service markets, grow its customer base, and manage its operations; EVgo's ability to adapt its assets and infrastructure to changes in industry and regulatory standards for EV charging; impediments to EVgo’s expansion plans, including permitting delays; the need to attract additional fleet operators as customers; potential adverse effects on EVgo’s revenue and gross margins if customers increasingly claim clean energy credits and, as a result, they are no longer available to be claimed by EVgo; risks related to EVgo’s dependence on its intellectual property; and risks that EVgo’s technology could have undetected defects or errors. Additional risks and uncertainties that could affect the Company’s financial results are included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of EVgo” in EVgo’s most recent Annual Report on Form 10-K, filed with the Securities and Exchange Commission (the “SEC”), as well as its other SEC filings, copies of which are available on EVgo’s website at investors.evgo.com, and on the SEC’s website at www.sec.gov. All forward-looking statements in this presentation are based on information available to EVgo as of the date hereof, and EVgo does not assume any obligation to update the forward-looking statements provided to reflect events that occur or circumstances that exist after the date on which they were made, except as required by applicable law. Use of Non-GAAP Financial Measures To supplement EVgo’s financial information, which is prepared and presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”), EVgo uses certain non-GAAP financial measures. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. EVgo uses these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. EVgo believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s performance by excluding certain items that may not be indicative of EVgo’s recurring core business operating results. EVgo believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing EVgo’s performance. These non-GAAP financial measures also facilitate management’s internal comparisons to the Company’s historical performance. EVgo believes these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by EVgo’s institutional investors and the analyst community to help them analyze the health of EVgo’s business. Reconciliations of these non-GAAP financial measures to the most comparable GAAP measures can be found in the tables included at the end of this presentation.

This presentation includes the following non-GAAP financial measures, in each case as defined below: “Adjusted Cost of Sales,” “Adjusted Cost of Sales as a Percentage of Revenue,” “Adjusted Gross Profit (Loss),” “Adjusted Gross Margin,” “Adjusted General and Administrative Expenses,” “Adjusted General and Administrative Expenses as a Percentage of Revenue,” “EBITDA,” “EBITDA Margin,” “Adjusted EBITDA” and “Adjusted EBITDA Margin.” EVgo believes these measures are useful to investors in evaluating EVgo’s performance. In addition, EVgo management uses these measures internally to establish forecasts, budgets, and operational goals to manage and monitor its business. EVgo believes that these measures help to depict a more meaningful representation of the performance of the underlying business, enabling EVgo to evaluate and plan more effectively for the future. EVgo defines Adjusted Cost of Sales as cost of sales before (i) depreciation, net of capital-build amortization, and (ii) share-based compensation. EVgo defines Adjusted Cost of Sales as a Percentage of Revenue as Adjusted Cost of Sales as a percentage of revenue. EVgo defines Adjusted Gross Profit (Loss) as revenue less Adjusted Cost of Sales. EVgo defines Adjusted Gross Margin as Adjusted Gross Profit (Loss) as a percentage of revenue. EVgo defines Adjusted General and Administrative Expenses as general and administrative expenses before (i) share-based compensation, (ii) loss on disposal of property and equipment, net of recoveries, and impairment expense, (iii) bad debt expense, and (iv) certain other items that management believes are not indicative of EVgo’s ongoing performance. EVgo defines Adjusted General and Administrative Expenses as a Percentage of Revenue as Adjusted General and Administrative Expenses as a percentage of revenue. EVgo defines EBITDA as net income (loss) before (i) depreciation, net of capital-build amortization, (ii) amortization, (iii) accretion, (iv) interest income, (v) interest expense, and (vi) income tax expense. EVgo defines EBITDA Margin as EBITDA as a percentage of revenue. EVgo defines Adjusted EBITDA as EBITDA plus (i) share-based compensation, (ii) loss on disposal of property and equipment, net of recoveries, and impairment expense, (iii) (gain) loss on investments, (iv) bad debt expense, (v) change in fair value of earnout liability, (vi) change in fair value of warrant liabilities, and (vii) certain other items that management believes are not indicative of EVgo’s ongoing performance. EVgo defines Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of revenue. Adjusted Cost of Sales, Adjusted Cost of Sales as a Percentage of Revenue, Adjusted Gross Profit (Loss), Adjusted Gross Margin, Adjusted General and Administrative Expenses, Adjusted General and Administrative Expenses as a Percentage of Revenue, EBITDA, EBITDA Margin, Adjusted EBITDA and Adjusted EBITDA Margin are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. These measures should not be considered as measures of financial performance under GAAP and the items excluded from or included in these metrics are significant components in understanding and assessing EVgo’s financial performance. These metrics should not be considered as alternatives to net income (loss) or any other performance measures derived in accordance with GAAP. Definitions of Non-GAAP Financial Measures 18
