PRELIMINARY PROSPECTUS SUPPLEMENT
(To Prospectus dated August 25, 2022)

EVgo Inc.

23,000,000 Shares

Class A Common Stock

​

The selling stockholder identified in this prospectus supplement ("Selling Stockholder") is offering 23,000,000 shares of our Class A common stock, $0.0001 par value per share ("Class A Common Stock"), pursuant to this prospectus supplement and the accompanying prospectus. We will not receive any of the proceeds from the sale of Class A Common Stock by the Selling Stockholder.

Our Class A Common Stock is listed on the Nasdaq Global Select Market ("Nasdaq") under the symbol "EVGO." On December 13, 2024, the last reported sale price per share of our Class A Common Stock on the Nasdaq was $6.09 per share.

Prior to the completion of this offering, we or one of our subsidiaries will redeem from the Selling Stockholder        units ("EVgo OpCo Units") of EVgo OpCo, LLC ("EVgo OpCo") and        shares of our Class B common stock, $0.0001 par value per share ("Class B Common Stock"), in exchange for        shares of Class A Common Stock ("Redemption").

We have two classes of authorized common stock: Class A Common Stock and Class B Common Stock. Each share of Class A Common Stock and Class B Common Stock entitles its holder to one vote per share. Immediately following completion of this offering and the Redemption (and assuming no exercise of the underwriters' option to purchase additional shares), the Selling Stockholder and its affiliates will own     % of our Class A Common Stock and     % of our Class B Common Stock, representing approximately     % of the voting power of our outstanding common stock. As a result, we expect to remain a "controlled company" within the meaning of the corporate governance standards of Nasdaq.

We are an "emerging growth company" and a "smaller reporting company" under applicable federal securities laws and therefore subject to reduced public company reporting requirements.

Investing in our Class A common stock involves a high degree of risk. See "Risk Factors" beginning on page S-10 of this prospectus supplement and any other risk factor included in the accompanying base prospectus and in the documents incorporated by reference in this prospectus supplement to read about factors you should consider before buying the Company's securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities to be issued under this prospectus supplement or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

​

Assumes no exercise of the underwriters' option to purchase additional shares of Class A Common Stock. See "Underwriting."​

​

The underwriters have the option to purchase up to 3,450,000 additional shares of Class A Common Stock on the same terms set forth above within 30 days from the date of this prospectus supplement. See "Underwriting." In the event of any exercise of such option, we or one of our subsidiaries will redeem from the Selling Stockholder a number of EVgo OpCo Units and shares of Class B Common Stock in exchange for the number of additional shares of Class A Common Stock purchased pursuant to such option.

Delivery of the shares of Class A Common Stock is expected to be made on or about          , 2024.

The date of this prospectus supplement is            , 2024.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risks described below and incorporated by reference to our most recent Annual Report on Form 10-K, any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus supplement and the accompanying prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement before acquiring any such securities. Our business, prospects, financial condition or operating results could be harmed by any of these risks, as well as other risks not known to us or that we consider immaterial as of the date of this prospectus supplement. The trading price of our securities could decline due to any of these risks, and, as a result, you may lose all or part of your investment. See "Incorporation by Reference."

Additional Risks Related to EVgo's Business

Future administrations at the federal and state level may create uncertainty for the EV sector and may have an adverse effect on our business, prospects, financial condition and operating results.

In order to encourage the use of EVs, the U.S. federal government and some state and local governments provide incentives to end users and owners of EVs and EV charging stations in the form of rebates, tax credits (including a $7,500 tax credit for new EVs and a $4,000 tax credit for used EVs) ("EV Tax Credits"), low-cost funding and other financial incentives that promote EV adoption and related EV charging infrastructure. The Infrastructure Investment and Jobs Act ("Bipartisan Infrastructure Law") and the Inflation Reduction Act of 2022 ("Inflation Reduction Act") included extensions, expansions and revisions of various tax credits relating to EVs and EV charging infrastructure and may provide more flexibility and options in monetizing such credits. In particular, the Inflation Reduction Act (i) expanded and extended tax credits for EV charging infrastructure and new EVs while also imposing new limitations and requirements for such credits, (ii) introduced tax credits for used EVs and commercial EVs and (iii) introduced the concept of transferability for certain tax credits, providing an additional option to monetize such credits.

Further, the National Electric Vehicle Infrastructure ("NEVI") Program, which was established by the Bipartisan Infrastructure Law, provides funding to states to strategically deploy EV charging stations and establish an interconnected network to facilitate data collection, access and reliability. In addition to NEVI funding, which has been made available to every state department of transportation to administer grant programs to support the deployment of charging infrastructure, a number of states also offer various rebates, grants and tax credits to incentivize both EV and EV service equipment purchases. Additionally, in many states, utilities offer rebates or other incentive programs, typically called "make-ready" programs, to incent the development of EV charging infrastructure.

Additionally, in March 2024, the Environmental Protection Agency introduced a rule requiring carmakers to meet strict tailpipe emissions limits ("Tailpipe Rule"), which is intended to incentivize increased EV production, with the goal of zero-emissions vehicles (such as EVs and hybrid vehicles) constituting over half of new vehicles sold in the United States by 2032.

However, incentives set by federal or state governments, as well as other government commitments and initiatives, may expire on a particular date, end when the allocated funding is exhausted, or may be reduced, modified or terminated as a matter of regulatory, executive or legislative policy. The impact of the Inflation Reduction Act and other government EV initiatives, including regulatory requirements and restrictions that may impact the ability of us and our competitors to take advantage of such initiatives, cannot be known with any certainty at this time, and we may not reap any or all of the expected benefits of the Inflation Reduction Act or the Bipartisan Infrastructure Law.

Future administrations at the federal and state level may create further uncertainty for the EV sector. For example, the incoming administration may enact policies or change regulations that adversely affect the growth of the EV market, including by eliminating the EV Tax Credits or the Tailpipe Rule, and may take additional steps to remove incentives for manufacturing and purchasing EVs. New or increased tariffs on imports to the United States following the recent Presidential election could also have a significant impact on

us, particularly our ability to source components for our charging network and the cost of such components. If such actions are taken, they would likely result in a suppressed EV market, fewer EVs on the road and lower demand for EV chargers, which would have an adverse effect on our business, prospects, financial condition and operating results.

Risks Related to the DOE Loan

Completion of the Project is substantially contingent on our ability to fully draw on our DOE Loan, which contains a number of conditions precedent to the first and each draw. Failure to satisfy the conditions required to fully draw down on our DOE Loan would materially and adversely affect our business, financial condition and results of operations.

The DOE Loan provides for up to $1.248 billion of loans, consisting of $1.05 billion of principal and up to $193 million of capitalized interest, to fund the construction, installment and deployment of approximately 7,500 new Stalls nationwide. We cannot, however, access these funds immediately or all at once, but only through periodic draws through the end of the Deployment Period, assuming eligible costs are incurred, and the first draw must occur prior to June 12, 2025. Our ability to receive Advances under the DOE Loan is subject to satisfaction of various conditions precedent, including but not limited to continued compliance with our representations and warranties, the required debt service coverage ratio, information requirements and repayment obligations. If we are unable to satisfy the conditions required to borrow under the DOE Loan and the DOE does not grant a waiver, and as a result we are not able to draw on the DOE Loan to fund the contemplated Stalls, we may have to delay completion of the overall Project, which could materially and adversely affect our business, financial condition and results of operations.

Our failure to comply with the covenants or other terms of the DOE Loan, including as a result of events beyond our control, could result in a default under the DOE Loan that could materially and adversely affect the ongoing viability of our business.

The DOE Loan contains customary events of default, including failure to make payments when due, failure to maintain the required debt service coverage ratio, the occurrence of a change of control or other breaches under the loan documents. During the continuation of an event of default, the DOE may exercise usual and customary remedies, including acceleration of the principal amount of the loan, assessment of fees and penalties and enforcement on the collateral. Any acceleration of amounts due under the DOE Loan would materially and adversely affect our business, financial condition and results of operations.

If we experience an event of default, we may need to seek a waiver from the DOE, and there can be no assurance the DOE will be willing to grant such waiver. The DOE's interests may not always be aligned with our interests. If our interests come into conflict with those of the DOE, including upon the occurrence of an event of a default under the DOE Loan, the DOE may choose to act in its self-interest. An event of default under the DOE Loan that is not waived by the DOE would materially and adversely affect our business, financial condition and results of operations.

The DOE Loan is secured by a substantial portion of our consolidated assets, resulting in the lack of substantial remaining assets available for incurring additional secured indebtedness.

Our obligations under the DOE Loan are secured on a first priority basis (subject to customary exceptions and permitted liens) by, and among other things, certain assets of the Borrower, which include the Stalls contributed to the Borrower by us pursuant to the terms of the DOE Loan, and the equity interests of the Borrower. Because a substantial portion of our consolidated assets secure the DOE Loan, we may not have substantial remaining assets available to secure other indebtedness. Accordingly, we may not be able to incur additional secured indebtedness in the future. Additionally, if the Borrower is unable to satisfy its payment obligations under the DOE Loan and an event of default occurs, the secured parties under the DOE Loan may foreclose on and sell the secured assets, which could prevent us from accessing such assets for our business and conducting our business as planned. Either of these events could materially and adversely affect our business, financial condition and results of operations.

The restrictions imposed on the Borrower under the DOE Loan limit our flexibility in operating the business of the Borrower and could limit our flexibility in operating our business.

The DOE Loan contains various affirmative and negative covenants that limit the ability of the Borrower and sometimes its affiliates to engage in specified types of transactions. These covenants, which are each subject to customary exceptions, impose limitations on the Borrower's ability to, among other things, without complying with the DOE Loan or obtaining the consent of the DOE:

•

incur additional indebtedness;

​

•

sell, lease, transfer or otherwise dispose of certain assets;

​

•

acquire another company or business or enter into a merger or similar transaction with third parties;

​

•

pay dividends and make other restricted payments;

​

•

encumber or permit liens on certain assets;

​

•

amend its organizational documents or capital structure; and

​

•

make certain investments.

​

Our board of directors or management team may believe that the Borrower taking any one of these actions would be in our best interests and the best interests of our stockholders. If that were the case and if we were unable to complete any of these actions because the DOE does not provide its consent, that could materially and adversely impact our business, financial condition and operating results.

We depend upon cash distributions from our subsidiaries, including the Borrower, to fund our operations, and restrictions on the Borrower's ability to distribute cash to us under the DOE Loan could adversely affect our business plans.

We conduct our operations through operating subsidiaries, including the Borrower. Accordingly, our ability to meet our obligations at the EVgo level depends upon the ability of our subsidiaries, including the Borrower, to distribute cash to us. In this regard, the ability of the Borrower to distribute cash to us is limited by certain restrictions and requirements to which the Borrower is subject under the terms of the DOE Loan. The terms of the DOE Loan generally prohibit the Borrower from making a dividend or distribution unless, among other things, (i) the Borrower has provided the required notice under the DOE Loan to the DOE of the proposed dividend or distribution, (ii) the Borrower has complied with funding requirements for the reserve accounts and operating account under the DOE Loan, (iii) the Borrower's debt to EBITDA ratio during the availability period for draws under the DOE Loan complies with the requirements set forth in the DOE Loan, and (iv) following the availability period for draws under the DOE Loan, the historical debt service coverage ratio and projected debt service coverage ratio comply with the requirements set forth in the DOE Loan. If these limitations were to materially impede the flow of cash to us, such restriction could materially and adversely affect our business, financial condition and results of operations.

We may need to raise additional funds, and these funds may not be available when needed or may only be available on unfavorable terms, which could impact our ability to fund our operations, our growth and the build-out of our network.

We may need to raise additional capital in the future to fund our operations, further scale our business and expand our charging network. We may raise additional funds through the issuance of equity, equity-related or debt securities, through obtaining credit from government or financial institutions or through grant funding. We cannot be certain that additional funds or incentives will be available on favorable terms when required, or at all, or that we will be able to capture expected grant funding under various existing and new state and local programs in the future. Interest rates have been elevated in recent periods, and, while they have recently fallen, if that trend does not continue, the cost of capital could remain high or increase in future periods. Any future indebtedness we incur would be effectively subordinated to the DOE Loan to the extent of the collateral securing the DOE Loan, and would be structurally subordinated to the existing and future indebtedness of our subsidiaries, including the DOE Loan. Additionally, the terms of the DOE Loan impose limitations on our ability to raise funds due to restrictive covenants relating to the Borrower's

ability to incur indebtedness and pledge assets. See "The restrictions imposed on the Borrower under the DOE Loan limit our flexibility in operating the business of the Borrower and could limit our flexibility in operating our business" above.

If we cannot raise additional funds when needed, our business, financial condition, and results of operations could be materially and adversely affected. If we raise funds through the issuance of debt securities or through loan arrangements, the terms for such securities or arrangements could require significant interest payments or contain restrictive covenants or other unfavorable terms and rank senior to the interests held by our stockholders. In addition, to the extent we raise funds through the sale of additional equity securities, the market price of our Class A Common Stock could be adversely affected and our stockholders would experience dilution. See Part I, Item IA, "Risk Factors - Risks Related to EVgo's Securities - The market price of EVgo's Class A common stock could be adversely affected by, and EVgo's stockholders may experience dilution as a result of, sales of substantial amounts of Class A common stock in the public or private markets, including sales by the Company, EVgo Holdings or other large holders" in our Annual Report on Form 10-K for the year ended December 31, 2023.

Risks Related to our "Up-C" Structure and the Tax Receivable Agreement

LS Power owns the majority of our voting stock and therefore has the right to appoint a majority of our board members, and its interests may conflict with those of other stockholders.

LS Power, the Selling Stockholder in this offering, owns the majority of our voting stock and is therefore entitled to appoint the majority of our board of directors. As a result, LS Power is able to substantially influence matters requiring our stockholder or board approval, including the election of directors, approval of any of our potential acquisitions, changes to our organizational documents and significant corporate transactions. This concentration of ownership makes it unlikely that any other holder or group of holders of Class A Common Stock will be able to affect the way we are managed or the direction of our business. The interests of LS Power with respect to matters potentially or actually involving or affecting us, such as future acquisitions, financings and other corporate opportunities and attempts to acquire us, may conflict with the interests of our other stockholders.

For example, LS Power may have different tax positions from us, especially in light of the Tax Receivable Agreement, that could influence its decisions regarding whether and when to support the disposition of assets or the incurrence or refinancing of new or existing indebtedness, or the termination of the Tax Receivable Agreement and acceleration of our obligations thereunder. In addition, the determination of future tax reporting positions, the structuring of future transactions and the handling of any challenge by any taxing authority to our tax reporting positions may take into consideration tax or other considerations of LS Power, including the effect of such positions on our obligations under the Tax Receivable Agreement, which may differ from our considerations or the considerations of other stockholders.

Our only principal asset is our interest in Thunder Sub, which, in turn, holds only units issued by EVgo OpCo; accordingly, we depend on distributions from EVgo OpCo and Thunder Sub to pay taxes, make payments under the Tax Receivable Agreement and cover our corporate and other overhead expenses.

We are a holding company and have no material assets other than our ownership interest in Thunder Sub. Thunder Sub holds only EVgo OpCo Units, which at the time immediately following the closing date of the Business Combination were equal to the number of shares of Class A Common Stock issued and outstanding after giving effect to the Business Combination and related transactions. Neither we nor Thunder Sub have independent means of generating revenue or cash flow. To the extent EVgo OpCo has available cash and subject to the terms of any current or future debt instruments, the amended and restated limited liability company agreement of EVgo OpCo entered into on July 1, 2021 ("EVgo OpCo A&R LLC Agreement") requires EVgo OpCo to make pro rata cash distributions to holders of EVgo OpCo Units, including Thunder Sub, in an amount sufficient to allow the Company Group to pay its taxes and to make payments under the Tax Receivable Agreement. We generally expect EVgo OpCo to fund such distributions out of available cash and if payments under the Tax Receivable Agreement are accelerated, we generally expect to fund such accelerated payments out of the proceeds of the change of control transaction giving rise to such acceleration. When EVgo OpCo makes distributions, the holders of EVgo OpCo Units will be entitled to receive proportionate distributions based on their interests in EVgo OpCo at the time of

such distribution. In addition, the EVgo OpCo A&R LLC Agreement requires EVgo OpCo to make non-pro rata payments to Thunder Sub to reimburse it for its corporate and other overhead expenses, which payments are not treated as distributions under the EVgo OpCo A&R LLC Agreement. To the extent that we need funds and EVgo OpCo or its subsidiaries are restricted from making such distributions or payments under applicable law or regulation or under the terms of any current or future financing arrangements, or are otherwise unable to provide such funds, our liquidity and financial condition could be materially adversely affected.

Moreover, because we have no independent means of generating revenue, our ability to make tax payments and payments under the Tax Receivable Agreement is dependent on the ability of EVgo OpCo to make distributions to Thunder Sub in an amount sufficient to cover the Company Group's tax obligations and obligations under the Tax Receivable Agreement. This ability, in turn, may depend on the ability of EVgo OpCo's subsidiaries to make distributions to it. The ability of EVgo OpCo, its subsidiaries and other entities in which it directly or indirectly holds an equity interest to make such distributions will be subject to, among other things, (i) the applicable provisions of Delaware law (or other applicable jurisdiction) that may limit the amount of funds available for distribution and (ii) restrictions in relevant debt instruments issued by EVgo OpCo or its subsidiaries and other entities in which it directly or indirectly holds an equity interest. To the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid.

We will be required to make payments under the Tax Receivable Agreement for certain tax benefits that we may claim, and the amounts of such payments could be significant.

In connection with the Business Combination, we entered into the Tax Receivable Agreement. This agreement generally provides for the payment by the Company Group to LS Power of 85% of the net cash savings, if any, in U.S. federal, state and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company Group actually realizes (or is deemed to realize in certain circumstances) in periods after the consummation of the Business Combination as a result of certain increases in tax basis available to the Company Group as a result of the Business Combination, the acquisition of EVgo OpCo Units pursuant to an exercise of the Redemption Right or the Call Right (as defined in the EVgo OpCo A&R LLC Agreement) (including any increases in tax basis relating to prior transfers of such EVgo OpCo Units that will be available to the Company Group as a result of its acquisition of such EVgo OpCo Units) and certain benefits attributable to imputed interest. The Company Group will retain the benefit of the remaining net cash savings, if any.

The term of the Tax Receivable Agreement commenced upon the consummation of the Business Combination and will continue until all tax benefits that are subject to the Tax Receivable Agreement have been utilized or expired and all required payments are made, unless the Company Group exercises its right to terminate the Tax Receivable Agreement (or the Tax Receivable Agreement is terminated due to other circumstances, including the Company Group's breach of a material obligation thereunder or certain mergers or other changes of control) and the Company Group makes the termination payment specified in the Tax Receivable Agreement. In addition, payments the Company Group makes under the Tax Receivable Agreement will be increased by any interest accrued from the due date (without extensions) of the corresponding tax return. As of September 30, 2024, no transactions occurred that resulted in a cash tax savings benefit that would have triggered the recording of a liability by the Company based on the terms of the Tax Receivable Agreement. However, the Redemption will provide the Company Group with certain increases in tax basis (and corresponding tax deductions) and the Company Group will be required to pay EVgo Holdings 85% of the net cash savings attributable to such increase in tax basis. Payments under the Tax Receivable Agreement are generally due on the due date of the Tax Return that reports such cash tax savings.

The payment obligations under the Tax Receivable Agreement are the Company Group's obligations and not obligations of EVgo OpCo and we expect that the payments the Company Group will be required to make under the Tax Receivable Agreement will be substantial. Estimating the amount and timing of the Company Group's realization of tax benefits subject to the Tax Receivable Agreement is by its nature imprecise. The actual increases in tax basis covered by the Tax Receivable Agreement, as well as the amount and timing of the Company Group's ability to use any deductions (or decreases in gain or increases in

loss) arising from such increases in tax basis, are dependent upon future events, including but not limited to the timing of redemptions of EVgo OpCo Units, the price of the Class A Common Stock at the time of each redemption, the extent to which such redemptions are taxable transactions, the amount of the redeeming member's tax basis in its EVgo OpCo Units at the time of the relevant redemption, the depreciation and amortization periods that apply to the increase in tax basis, the amount, character and timing of taxable income the Company Group generates in the future, the timing and amount of any earlier payments that the Company Group may have made under the Tax Receivable Agreement, the U.S. federal income tax rate then applicable and the portion of the Company Group's payments under the Tax Receivable Agreement that constitute imputed interest or give rise to depreciable or amortizable tax basis. Accordingly, estimating the amount and timing of payments that may become due under the Tax Receivable Agreement is also by its nature imprecise. For purposes of the Tax Receivable Agreement, net cash savings in tax generally are calculated by comparing the Company Group's actual tax liability (determined by using the actual applicable U.S. federal income tax rate and an assumed combined state and local income tax rate) to the amount the Company Group would have been required to pay had it not been able to utilize any of the tax benefits subject to the Tax Receivable Agreement. Thus, the amount and timing of any payments under the Tax Receivable Agreement are also dependent upon significant future events, including those noted above in respect of estimating the amount and timing of the Company Group's realization of tax benefits. Any distributions made by EVgo OpCo to the Company Group to enable the Company Group to make payments under the Tax Receivable Agreement, as well as any corresponding pro rata distributions made to the other holders of EVgo OpCo Units, could have an adverse impact on our liquidity.

Payments under the Tax Receivable Agreement will not be conditioned upon a holder of rights under the Tax Receivable Agreement having an ownership interest in the Company or EVgo OpCo. In addition, certain rights of the holders of EVgo OpCo Units (including the right to receive payments) under the Tax Receivable Agreement will be transferable in connection with transfers permitted under the EVgo OpCo A&R LLC Agreement of the corresponding EVgo OpCo Units or after the corresponding EVgo OpCo Units have been acquired pursuant to the Redemption Right or Call Right.

In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits, if any, the Company Group realizes in respect of the tax attributes subject to the Tax Receivable Agreement.

If we experience a change of control (as defined under the Tax Receivable Agreement, which includes certain mergers, asset sales and other forms of business combinations) or the Tax Receivable Agreement terminates early (at the Company Group's election or as a result of the Company Group's breach), the Company Group would be 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 (determined by applying a discount rate equal to one-year LIBOR (or an agreed successor rate, if applicable) plus 100 basis points), and such early termination payment is expected to be substantial. The calculation of anticipated future payments will be 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 or its subsidiaries, other than EVgo OpCo) outstanding on the termination date or change of control date, as applicable, are deemed to be redeemed on such date. Any early termination payment may be made significantly in advance of and may materially exceed, the actual realization, if any, of the future tax benefits to which the early termination payment relates.

If we experience a change of control (as defined under the Tax Receivable Agreement) or the Tax Receivable Agreement otherwise terminates early (at the Company Group's election or as a result of the Company Group's breach), the Company Group's obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, or other forms of business combinations or changes of control. If the Company Group's obligation to make payments under the Tax Receivable Agreement is accelerated as a result of a change of control, we generally expect the accelerated payments due under the Tax Receivable Agreement to be funded out of the proceeds of the change of control transaction giving rise to such acceleration. However, the Company Group may be required to fund such payment from other sources and as a result, any early termination of the Tax Receivable Agreement could have a substantial negative

impact on our liquidity. We do not currently expect to cause an acceleration due to the Company Group's breach and we do not currently expect that the Company Group would elect to terminate the Tax Receivable Agreement early, except in cases where the early termination payment would not be material. There can be no assurance that the Company Group will be able to meet its obligations under the Tax Receivable Agreement.

If the Company Group's payment obligations under the Tax Receivable Agreement are accelerated upon certain mergers, other forms of business combinations or other changes of control, the consideration payable to holders of Class A common stock could be substantially reduced.

If we experience a change of control (as defined under the Tax Receivable Agreement, which includes certain mergers, asset sales and other forms of business combinations), then the Company Group's obligations under the Tax Receivable Agreement would be based upon certain assumptions and deemed events set forth in the Tax Receivable Agreement and in such situations, payments under the Tax Receivable Agreement may be significantly in advance of and may materially exceed, the actual realization, if any, of the future tax benefits to which the payment relates. As a result of the Company Group's payment obligations under the Tax Receivable Agreement, holders of Class A Common Stock could receive substantially less consideration in connection with a change of control transaction than they would receive in the absence of such obligation. Further, the Company Group's payment obligations under the Tax Receivable Agreement will not be conditioned upon holders of EVgo OpCo Units having a continued interest in us or EVgo OpCo. Accordingly, the interests of the holders of EVgo OpCo Units may conflict with those of the holders of Class A Common Stock. See "Risk Factors - In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual benefits, if any, the Company Group realizes in respect of the tax attributes subject to the Tax Receivable Agreement."

We will not be reimbursed for any payments made under the Tax Receivable Agreement in the event that any tax benefits are subsequently disallowed.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that the Company Group will determine and the IRS or another tax authority may challenge all or part of the tax basis increases upon which payments under the Tax Receivable Agreement are based, as well as other related tax positions the Company Group takes and a court could sustain such challenge. The holders of EVgo OpCo Units will not reimburse us for any payments previously made under the Tax Receivable Agreement if any tax benefits that have given rise to payments under the Tax Receivable Agreement are subsequently disallowed, except that excess payments made to any holder of EVgo OpCo Units will be netted against future payments that would otherwise be made to such holder of EVgo OpCo Units, if any, after the Company Group's determination of such excess (which determination may be made a number of years following the initial payment and after future payments have been made). As a result, in such circumstances, the Company Group could make payments that are greater than its actual cash tax savings, if any and may not be able to recoup those payments, which could materially adversely affect its liquidity.

If EVgo OpCo were to become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes, we and EVgo OpCo might be subject to potentially significant tax inefficiencies and we would not be able to recover payments previously made by it under the Tax Receivable Agreement even if the corresponding tax benefits were subsequently determined to have been unavailable due to such status.

We intend to operate such that EVgo OpCo does not become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes. A "publicly traded partnership" is a partnership the interests of which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof. Under certain circumstances, redemptions of EVgo OpCo Units pursuant to the Redemption Right (or the Call Right) or other transfers of EVgo OpCo Units could cause EVgo OpCo to be treated as a publicly traded partnership. Applicable Treasury regulations provide for certain safe harbors from treatment as a publicly traded partnership and we intend to operate such that redemptions or other transfers of EVgo OpCo Units qualify for one or more such safe harbors. For example, we intend to limit the number of holders of EVgo OpCo Units and the EVgo OpCo A&R LLC Agreement, which was entered into in connection with the consummation of the Business Combination, provides for limitations on the ability of holders of EVgo OpCo Units to transfer their EVgo OpCo Units and provides

Thunder Sub, as the managing member of EVgo OpCo, with the right to impose restrictions (in addition to those already in place) on the ability of holders of EVgo OpCo Units to redeem their EVgo OpCo Units pursuant to the Redemption Right (or Call Right) to the extent we believe it is necessary to ensure that EVgo OpCo will continue to be treated as a partnership for U.S. federal income tax purposes.

If EVgo OpCo were to become a publicly traded partnership taxable as a corporation for U.S. federal income tax purposes, significant tax inefficiencies might result for the Company and EVgo OpCo, including as a result of the Company Group's inability to file a consolidated U.S. federal income tax return with EVgo OpCo. In addition, the Company Group may not be able to realize tax benefits covered under the Tax Receivable Agreement and the Company Group would not be able to recover any payments previously made by it under the Tax Receivable Agreement, even if the corresponding tax benefits (including any claimed increase in the tax basis of EVgo OpCo's assets) were subsequently determined to have been unavailable.

Risks Related to our Common Stock and This Offering

Future sales of our Class A Common Stock, or the perception that such sales may occur, may depress our stock price.

We may sell shares of Class A Common Stock in the future. If we sell substantial amounts of our Class A Common Stock in the public market, or if the market perceives that such sales may occur, the market price of our Class A Common Stock could fall and it may become more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. We cannot predict the size of future issuances or sales of our Class A Common Stock or the effect, if any, that future issuances and sales of shares of our Class A Common Stock will have on the market price of our Class A Common Stock.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our Class A Common Stock or other securities convertible into or exchangeable for our Class A Common Stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by any investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our Class A Common Stock, or securities convertible or exchangeable into Class A Common Stock, in future transactions may be higher or lower than the price per share paid by any investors in this offering.

The market price of our Class A Common Stock may be volatile and adversely affected by market conditions affecting the stock markets in general, and purchasers of our Class A Common Stock could incur substantial losses.

Securities markets have from time to time experienced extreme price and volume fluctuations and such market conditions may, in turn, result in volatility in the level of, and fluctuations in, the market price of our Class A Common Stock, which may be unrelated or disproportionate to changes in our operating performance. These broad market fluctuations, as well as general market, economic and political conditions, such as recessions, tariffs or potential application thereof, loss of investor confidence or interest rate changes, may negatively affect our business and adversely affect the market price of the Class A Common Stock. If any of the foregoing occurs, it could result in purchasers in this offering losing some or all of the value of their investment.

We do not currently intend to pay dividends on our Class A Common Stock, and any return to investors is expected to come, if at all, only from potential increases in the price of our Class A Common Stock.

We have never declared or paid cash dividends on our capital stock, and you should not rely on an investment in our Class A Common Stock to provide dividend income. We anticipate that we will retain all of our future earnings, if any, to finance the growth and development of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. As a result, capital appreciation, if any, of our Class A Common Stock will be your sole source of gain for the foreseeable future.

USE OF PROCEEDS

The Selling Stockholder is selling all of the shares of Class A Common Stock being sold in this offering. Accordingly, we will not receive any proceeds from the sale of shares of our Class A Common Stock being sold in this offering. See "Underwriting" and "Selling Stockholder."

DIVIDEND POLICY

We have not paid any cash dividends on the Class A Common Stock to date. The payment of cash dividends is subject to the discretion of our board of directors and may be affected by various factors, including our future earnings, financial condition, capital requirements, share repurchase activity, current and future planned strategic growth initiatives, levels of indebtedness, and other considerations our board of directors deems relevant.

CAPITALIZATION

The following table sets forth our cash, cash equivalents and restricted cash and our capitalization as of September 30, 2024:

•

on an actual basis; and

​

•

on an as adjusted basis to reflect (1) this offering and (2) the Redemption (assuming no exercise of the underwriters' option to purchase additional shares).

​

You should read this table together with our consolidated financial statements and the related notes included in our Quarterly Report on Form 10-Q filed with the SEC on November 12, 2024 and the section titled "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in such Quarterly Report.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF OUR CLASS A COMMON STOCK

The following is a discussion of the material U.S. federal income tax considerations related to the ownership and disposition by Non-U.S. Holders (as defined below) of shares of Class A Common Stock. This discussion applies only to shares of Class A Common Stock that are held as a capital asset for U.S. federal income tax purposes (generally property held for investment).

This discussion is based on the provisions of the Internal Revenue Code of 1986, as amended from time to time ("Code"), U.S. Treasury regulations, administrative rulings and judicial decisions, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect. We cannot assure you that a change in law will not significantly alter the tax considerations that we describe in this summary. We have not sought any ruling from the U.S. Internal Revenue Service ("IRS") or formal written opinion from our tax advisors with respect to the statements made and the positions or conclusions described in the following summary. Such statements, positions and conclusions are not free from doubt, and there can be no assurance that your tax advisor, the IRS or a court will agree with such statements and conclusions.

This summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws, any tax treaties or any other tax law other than U.S. federal income tax law. Furthermore, this discussion does not address all U.S. federal income tax considerations that may be relevant to a particular holder in light of the holder's circumstances or that may be relevant to certain categories of investors that may be subject to special rules, such as:

•

our founders, sponsor, officers or directors or other holders of shares of our Class B Common Stock or private placement warrants;

​

•

banks, insurance companies or other financial institutions;

​

•

tax-exempt or governmental organizations;

​

•

"qualified foreign pension funds" as defined in Section 897(l)(2) of the Code (or any entities all of the interests of which are held by a qualified foreign pension fund);

​

•

dealers in securities or foreign currencies;

​

•

traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

​

•

"controlled foreign corporations," "passive foreign investment companies" and corporations that accumulate earnings to avoid U.S. federal income tax;

​

•

entities or arrangements treated as partnerships or pass-through entities for U.S. federal income tax purposes or holders of interests therein (including S-corporations, regulated investment companies and real estate investment trusts);

​

•

persons deemed to sell shares of Class A Common Stock under the constructive sale provisions of the Code;

​

•

persons that acquired shares of Class A Common Stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

​

•

persons that actually or constructively own five percent or more of any class of our shares or of the total combined voting power or total value of our equity interests;

​

•

persons that hold shares of Class A Common Stock as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction or other integrated investment or risk reduction transaction; and

​

•

persons subject to the alternative minimum tax.

​

HOLDERS ARE ENCOURAGED TO CONSULT WITH THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING ANY POTENTIAL FUTURE CHANGES THERETO) TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF CLASS A

COMMON STOCK ARISING UNDER ANY OTHER TAX LAWS, INCLUDING BUT NOT LIMITED TO THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Non-U.S. Holder Defined

A "Non-U.S. Holder" is a beneficial owner of shares of Class A Common Stock (other than an entity treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes, any of the following:

•

an individual citizen or resident of the United States;

​

•

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

​

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source;

​

•

a trust (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more "United States persons" ​(within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (B) that has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

​

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds shares of Class A Common Stock, the tax treatment of a partner in such partnership might depend upon the status of the partner or the partnership, upon the activities of the partnership and upon certain determinations made at the partnership or partner level. Accordingly, we urge partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) to consult with their tax advisors regarding the U.S. federal income and other tax considerations of the ownership and disposition of shares of Class A Common Stock by such partnership.

Distributions

As discussed under the section entitled "Dividend Policy" above, we do not currently anticipate paying dividends. If we pay distributions of cash or other property to the holders of our Class A Common Stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of the holder's adjusted tax basis in Class A Common Stock, that will be applied against and reduce (but not below zero) the holder's adjusted tax basis in Class A Common Stock. Any remaining portion of the distribution will be treated as gain from the sale or exchange of Class A Common Stock and will be treated as described below under "- Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Common Stock" below.

Subject to the withholding requirements under FATCA (as defined below) and other than with respect to effectively connected dividends, each of which is discussed below, any distribution treated as a dividend paid to a Non-U.S. Holder on Class A Common Stock generally will be subject to U.S. withholding tax at the rate of 30% of the gross amount of the distribution (unless an applicable income tax treaty provides for a lower rate). To receive the benefit of a reduced treaty rate, a Non-U.S. Holder must provide the applicable withholding agent with an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) certifying qualification for the reduced rate. In the case of any constructive dividend, it is possible that this tax would be withheld from any amount owed to a Non-U.S. Holder by the applicable withholding agent, including, if applicable, cash distributions on other property or sale proceeds from warrants or other property subsequently paid or credited to such holder.

Any portion of a distribution that is treated as a dividend paid to a Non-U.S. Holder that is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, that is treated as attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States) generally will be taxed on a net income basis at the rates and in

the manner generally applicable to United States persons. Such effectively connected dividends will not be subject to U.S. withholding tax if the Non-U.S. Holder satisfies certain certification requirements by providing the applicable withholding agent with a properly executed IRS Form W-8ECI certifying eligibility for exemption. If the Non-U.S. Holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Common Stock

Subject to the discussion below under "- Information Reporting and Backup Withholding," a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other disposition of Class A Common Stock, unless:

•

the Non-U.S. Holder is an individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met;

​

•

such gain is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is treated as attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States); or

​

•

shares of Class A Common Stock constitute United States real property interests by reason of our status as a "United States real property holding corporation" ​(a "USRPHC") for U.S. federal income tax purposes and, as a result, such gain is treated as effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States.

​

A Non-U.S. Holder described in the first bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as specified by an applicable income tax treaty) on the amount of such gain, which generally may be offset by U.S. source capital losses.

A Non-U.S. Holder whose gain is described in the second bullet point above or, subject to the exceptions described in the next paragraph, the third bullet point above, generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons unless an applicable income tax treaty provides otherwise. If the Non-U.S. Holder is a corporation for U.S. federal income tax purposes whose gain is described in the second bullet point above, such gain would also be included in its effectively connected earnings and profits (as adjusted for certain items), which may be subject to a branch profits tax (at a 30% rate or such lower rate as provided under an applicable income tax treaty).

Generally, a corporation is a USRPHC if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business, as determined for U.S. federal income tax purposes. We do not believe we currently are or will become a United States real property holding corporation; however, there can be no assurance in this regard. If we were to become a USRPHC, as long as our Class A Common Stock is or continues to be "regularly traded on an established securities market" (within the meaning of the U.S. Treasury regulations, referred to herein as "regularly traded"), a Non-U.S. Holder that actually or constructively owns, or owned at any time during the shorter of the five-year period ending on the date of the disposition or the Non-U.S. Holder's holding period, more than 5% of Class A Common Stock will be treated as disposing of a United States real property interest and will be taxable on gain realized on the disposition thereof as a result of our status as a USRPHC. It is unclear how a Non-U.S. Holder's ownership of warrants will affect the determination of whether such Non-U.S. Holder owns more than 5% of Class A Common Stock. We can provide no assurance as to our future status as a USRPHC or as to whether our Class A Common Stock will continue to be treated as regularly traded.

If we were to become a USRPHC and our Class A Common Stock were not considered to be regularly traded on an established securities market, a Non-U.S. Holder (regardless of the percentage of Class A Common Stock owned) would be treated as disposing of a United States real property interest and would

be subject to U.S. federal income tax on a taxable disposition of Class A Common Stock (as described in the preceding paragraph), and a 15% withholding tax would apply to the gross proceeds from any such disposition.

Non-U.S. Holders are encouraged to consult with their tax advisors regarding the tax consequences related to ownership in a USRPHC.

Information Reporting and Backup Withholding

Any distributions paid to a Non-U.S. Holder must be reported annually to the IRS and to the Non-U.S. Holder. Copies of these information returns may be made available to the tax authorities in the country in which the Non-U.S. Holder resides or is established. Payments of dividends to a Non-U.S. Holder generally will not be subject to backup withholding if the Non-U.S. Holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form).

Payments of the proceeds from a sale or other disposition by a Non-U.S. Holder of Class A Common Stock effected by or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate) unless the Non-U.S. Holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of Class A Common Stock effected outside the United States by a non-U.S. office of a broker.

However, unless such broker has documentary evidence in its records that the Non-U.S. Holder is not a United States person and certain other conditions are met, or the Non-U.S. Holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of our common stock effected outside the United States by such a broker if it has certain relationships within the United States.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund generally may be obtained, provided that the required information is timely furnished to the IRS. Non-U.S. Holders should consult with their own tax advisors regarding the application of the U.S. information reporting and backup withholding rules to them in their particular circumstances.

Additional Withholding Requirements Under FATCA

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and administrative guidance issued thereunder ("FATCA"), impose a 30% withholding tax on any dividends (including constructive dividends) on shares of Class A Common Stock and, subject to the proposed U.S. Treasury regulations discussed below, on proceeds from sales or other dispositions of shares of Class A Common Stock, if paid to a "foreign financial institution" or a "non-financial foreign entity" ​(each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with U.S. owners), (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any "substantial United States owners" ​(as defined in the Code) or provides the applicable withholding agent with a certification identifying the direct and indirect substantial United States owners of the entity (in either case, generally on an IRS Form W-8BEN-E), or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these rules may be subject to different rules. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes. While gross proceeds from a sale or other disposition of shares of Class A Common Stock paid after January 1,

2019 would have originally been subject to withholding under FATCA, proposed U.S. Treasury regulations provide that such payments of gross proceeds do not constitute withholdable payments. Taxpayers may generally rely on these proposed U.S. Treasury regulations until they are revoked or final U.S. Treasury regulations are issued. Prospective investors are encouraged to consult with their own tax advisors regarding the effects of FATCA on an investment in Class A Common Stock.

HOLDERS CONSIDERING THE OWNERSHIP AND DISPOSITION OF CLASS A COMMON STOCK ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF ANY OTHER TAX LAWS, INCLUDING BUT NOT LIMITED TO, U.S. FEDERAL ESTATE AND GIFT TAX LAWS AND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

SELLING STOCKHOLDER

The following table sets forth information regarding the beneficial ownership of our common stock by the Selling Stockholder, the number of shares of our Class A Common Stock offered hereby by the Selling Stockholder and information with respect to shares to be beneficially owned by the Selling Stockholder after completion of this offering and the Redemption. The number of shares of common stock outstanding and percentages of beneficial ownership provided in the table below (i) are based on the beneficial ownership as of December 15, 2024 and are based on 107,692,448 shares of Class A Common Stock and 195,800,000 shares of Class B Common Stock outstanding as of December 10, 2024 and (ii) do not give effect to any exercise of the underwriters' option to purchase additional shares

Beneficial ownership has been determined under rules promulgated by the SEC. Under such rules, a person is deemed to be a "beneficial owner" of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person's ownership percentage, but not for purposes of computing any other person's percentage.

​

(1)

Represents percentage of voting power of Class A Common Stock and Class B Common Stock voting together as a single class. Each share of Class B Common Stock has no economic rights but entitles the holder thereof to one vote for each EVgo OpCo Unit held by such holder. Accordingly, the holders of Class B Common Stock collectively have a number of votes in EVgo equal to the number of EVgo OpCo Units that they hold.

​

(2)

Includes all 195,800,000 shares of Class B Common Stock owned by EVgo Holdings LLC, a Delaware limited liability company ("EVgo Holdings"), which is controlled by EVgo Member Holdings, LLC, a Delaware limited liability company ("Member Holdings"). Member Holdings directly owns 5,882,352 shares (or 5.5%) of Class A Common Stock. The sole member of Member Holdings is LS Power Equity Partners IV, L.P., a Delaware limited partnership ("LSPEP IV"). LS Power Partners IV, LP, a Delaware limited partnership ("LSPEP IV GP"), is the general partner of LSPEP IV. The general partner of LSPEP IV GP is LS Power Fund IV GP, LLC, a Delaware limited liability company ("LSPEP IV Ultimate GP"), of whom LS Power Equity Advisors, LLC, a Delaware limited liability company ("LSP Advisors" and together with EVgo Holdings, Member Holdings, LSPEP IV, LSPEP IV GP and LSPEP IV Ultimate GP, the "LS Power Entities"), is the sole member. Each of LSPEP IV, LSPEP IV GP, LSPEP IV Ultimate GP and LSP Advisors may be deemed to have shared voting and investment power with respect to the shares directly owned by EVgo Holdings and Member Holdings and therefore may be deemed to beneficially own such shares. Mr. Nanus, through his position, relationship and/or affiliation with the LS Power Entities, may have shared voting and investment power with respect to the shares beneficially owned by the LS Power Entities. As such, Mr. Nanus may be deemed to have or share beneficial ownership of the shares beneficially owned by the LS Power Entities. Mr. Nanus disclaims beneficial ownership of such shares. The address of the principal business and principal office of each of the LS Power Entities is 1700 Broadway, 35th Floor, New York, New York 10019.

UNDERWRITING

The Selling Stockholder is offering the shares of Class A Common Stock described in this prospectus supplement through a number of underwriters. J.P. Morgan Securities LLC, Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC and Evercore Group L.L.C. are acting as joint book-running managers of the offering and as representatives of the underwriters. We have entered into an underwriting agreement with the underwriters and the Selling Stockholder. Subject to the terms and conditions of the underwriting agreement, the Selling Stockholder has agreed to sell to the underwriters, and each underwriter has severally agreed to purchase from the Selling Stockholder, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of shares of Class A Common Stock set forth next to its name in the following table:

The underwriters are committed to purchase all of the Class A Common Stock being offered if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the Class A Common Stock directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $      per share. Any such dealers may resell shares of Class A Common Stock to certain other brokers or dealers at a discount of up to $      per share from the public offering price. After the offering of the shares to the public, if all of the Class A Common Stock is not sold at the public offering price, the underwriters may change the offering price and the other selling terms. Sales of any shares made outside of the United States may be made by affiliates of the underwriters. The offering of the Class A Common Stock by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

The underwriters have an option to buy up to 3,450,000 additional shares of Class A Common Stock from the Selling Stockholder to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of Class A Common Stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of Class A Common Stock less the amount paid by the underwriters to the Selling Stockholder per share of Class A Common Stock. The underwriting fee is $      per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters' option to purchase additional shares.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $      . We have agreed to reimburse the underwriters for expenses of up to $25,000. The underwriters have agreed to reimburse the Selling Stockholder for certain of its offering-related expenses. The Selling Stockholder has engaged Solebury Capital LLC ("Solebury"), an independent financial adviser and a member of FINRA, to provide certain financial consulting services in connection with this offering.

A prospectus supplement in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the SEC a registration statement under the Securities Act relating to, any shares of Class A Common Stock or any securities convertible into or exercisable or exchangeable for shares of Class A Common Stock, or publicly disclose the intention to undertake any such action, or (ii) enter into any swap or other agreement that transfers all or a portion of the economic consequences of ownership of any shares of Class A Common Stock or any such other securities (regardless of whether any such transactions are to be settled by the delivery of shares of Class A Common Stock or such other securities, in cash or otherwise), in each case without the prior written consent of J.P. Morgan Securities LLC, for a period of 60 days after the date of this prospectus supplement (the "restricted period"), other than the shares of Class A Common Stock to be sold in this offering.

The restrictions on our actions, as described above, do not apply to certain transactions, including (i) the issuance of shares of Class A Common Stock or securities convertible into or exercisable for shares of Class A Common Stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of restricted stock units ("RSUs") (including net settlement), in each case outstanding on the date of the underwriting agreement and described in this prospectus supplement; (ii) grants of stock options, stock awards, restricted stock, RSUs, or other equity awards and the issuance of shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for shares of Class A Common Stock (whether upon the exercise of stock options or otherwise) to our employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the closing of this offering and described in this prospectus supplement; or (iii) our filing of any registration statement on Form S-3 or post-effective amendment to any registration statement on Form S-3 pursuant to that certain Registration Rights Agreement dated as of July 1, 2021 by and among EVgo and the shareholders named therein; (iv) our filing of any registration statement on Form S-8 or post-effective amendment to any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan in effect on the date of the underwriting agreement and described in this prospectus supplement or any assumed benefit plan pursuant to an acquisition or similar strategic transaction; or (v) establishing or facilitating the establishment of a trading plan on behalf of us or one of our stockholders, officers or directors pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock, provided that (a) such plan does not provide for the transfer of shares of Class A Common Stock during the restricted period, as defined below, and (b) to the extent we are required to or voluntarily make a public announcement or filing under the Exchange Act regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of shares of Class A Common Stock may be made under such plan during the restricted period.

Our directors and executive officers and the Selling Stockholder (such persons, the "lock-up parties") have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each lock-up party, with limited exceptions, during the restricted period, may not (and may not cause any of their direct or indirect affiliates to), without the prior written consent of J.P. Morgan Securities LLC, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any

The restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the underwriters and the lock-up parties do not apply, subject in certain cases to various conditions, to certain transactions, including (a) transfers of lock-up securities: (i) as bona fide gifts, or for bona fide estate planning purposes, to an immediate family member or to any trust for the direct or indirect benefit of the lock-up party or any immediate family member, (ii) by will or intestacy, (iii) to a partnership, limited liability company or other entity of which the lock-up party and its immediate family members are the legal and beneficial owner of all of the outstanding equity securities or similar interests, (iv) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iii), (v) in the case of a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the lock-up party, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the lock-up party or its affiliates or (B) as part of a distribution to members or stockholders of the lock-up party, (vi) by operation of law, (vii) to us from an employee upon death, disability or termination of employment of such employee, (viii) as part of a sale of lock-up securities acquired in open market transactions after the completion of this offering, (ix) in connection with the vesting, settlement or exercise of RSUs, options, warrants or other rights to purchase shares of Class A Common Stock (including, in each case, by way of "net" or "cashless" exercise), including for the payment of exercise price and tax and remittance payments, or in open market sales solely in an amount sufficient to cover withholding taxes due in connection with the vesting, settlement or exercise of such RSUs, options, warrants or rights, (x) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction approved by our board of directors and made to all our stockholders involving a change in control, provided that if such transaction is not completed, all such lock-up securities would remain subject to the same restrictions during the restricted period, or (xi) pursuant to a trading plan pursuant to Rule 10b5-1 under the Exchange Act established prior to the date of the underwriting agreement; (b) exercise of the options, settlement of RSUs or other equity awards, or the exercise of warrants granted pursuant to plans described in this prospectus, provided that any lock-up securities received upon such exercise, vesting or settlement would be subject to the same restrictions during the restricted period; (c) the conversion of outstanding preferred stock, warrants to acquire preferred stock, or convertible securities into shares of Class A Common Stock or warrants to acquire shares of Class A Common Stock, provided that any Class A Common Stock or warrant received upon such conversion would be subject to the same restrictions during the restricted period; (d) the establishment by lock-up parties of trading plans under Rule 10b5-1 under the Exchange Act, provided that any such plan (i) does not provide for the transfer of lock-up securities during the restricted period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by us regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of shares of Class A Common Stock may

J.P. Morgan Securities LLC, in its sole discretion, may release the securities subject to any of the lock-up agreements with the underwriters described above, in whole or in part at any time.

We and the Selling Stockholder have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

The Class A Common Stock is listed/quoted on the Nasdaq under the symbol "EVGO."

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of Class A Common Stock in the open market for the purpose of preventing or retarding a decline in the market price of the Class A Common Stock while this offering is in progress. These stabilizing transactions may include making short sales of Class A Common Stock, which involves the sale by the underwriters of a greater number of shares of Class A Common Stock than they are required to purchase in this offering, and purchasing shares of Class A Common Stock on the open market to cover positions created by short sales. Short sales may be "covered" shorts, which are short positions in an amount not greater than the underwriters' option to purchase additional shares referred to above, or may be "naked" shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Class A Common Stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the Class A Common Stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase Class A Common Stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the Class A Common Stock or preventing or retarding a decline in the market price of the Class A Common Stock, and, as a result, the price of the Class A Common Stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the Nasdaq Global Select Market, in the over-the-counter market or otherwise.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and our affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and any accompanying prospectus supplement, or some of the information incorporated herein by reference, contains statements that are forward-looking and as such are not historical facts. These forward-looking statements include, without limitation, statements regarding future financial performance, business strategies, expansion plans, future results of operations, estimated revenues, losses, projected costs, prospects, plans and objectives of management. These forward-looking statements are based on EVgo management's current expectations, estimates, projections and beliefs, as well as a number of assumptions concerning future events, and are not guarantees of performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts.

Forward-looking statements in this prospectus and any accompanying prospectus supplement and in any document incorporated by reference in this prospectus may include, for example, statements about:

•

changes adversely affecting EVgo's business;

​

•

the risks associated with cyclical demand for EVgo's services and vulnerability to industry downturns and regional or national downturns;

​

EVgo's SEC filings are available publicly on the SEC website at www.sec.gov. The forward-looking statements contained in this prospectus are based on EVgo's current expectations and beliefs concerning future developments and their potential effects on the Company. There can be no assurance that future developments affecting the Company will be those that the Company has anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond EVgo's control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of EVgo's assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Accordingly, forward-looking statements in this prospectus and in any document incorporated herein by reference should not be relied upon as representing EVgo's views as of any subsequent date, and the Company undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

RISK FACTORS

An investment in EVgo's securities involves a high degree of risk. You should carefully consider the risks incorporated by reference to EVgo's most recent Annual Report on Form 10-K, any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus as updated by EVgo's subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before acquiring any such securities. EVgo's business, prospects, financial condition or operating results could be harmed by any of these risks, as well as other risks not known to it or that it considers immaterial as of the date of this prospectus. The trading price of EVgo's securities could decline due to any of these risks, and, as a result, you may lose all or part of your investment. See "Incorporation by Reference."

USE OF PROCEEDS

Unless we inform you otherwise in a prospectus supplement or free writing prospectus, we intend to use the net proceeds from the sale of securities we are offering for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of any indebtedness or other corporate obligations, financing of capital expenditures and acquisitions and investment in existing and future projects. Any specific allocation of the net proceeds of an offering of securities to a specific purpose will be determined at the time of the offering and will be described in an accompanying prospectus supplement or free writing prospectus.

All of the Class A Common Stock and Private Placement Warrants offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts. We will not receive any of the proceeds from these sales.

We will receive up to an aggregate of approximately $208.1 million from the exercise of the Warrants, assuming the exercise in full of all of the Warrants for cash. We expect to use the net proceeds from the exercise of the Warrants for general corporate purposes. We will have broad discretion over the use of proceeds from the exercise of the Warrants. There is no assurance that the holders of the Warrants will elect to exercise any or all of such Warrants. To the extent that the Warrants are exercised on a "cashless basis," the amount of cash we would receive from the exercise of the Warrants will decrease.

REDEMPTION OF OPCO UNITS AND CLASS B COMMON STOCK

EVgo is organized in an "Up-C" structure and operates its business through CRIS Thunder Merger Sub, LLC ("Thunder Sub") and its subsidiaries, including EVgo OpCo. On the CRIS Close Date, Thunder Sub and EVgo Holdings entered into the amended and restated limited liability company agreement of EVgo OpCo (the "EVgo OpCo A&R LLC Agreement"). Pursuant to the EVgo OpCo A&R LLC Agreement, each OpCo Unit (other than an OpCo Unit held by Thunder Sub), together with one share of Class B Common Stock, will be redeemable, subject to certain conditions, for either one share of Class A Common Stock or, at EVgo OpCo's election, an amount of cash approximately equivalent to the market value of one share of Class A Common Stock. As holders of OpCo Units exchange their OpCo Units and Class B Common Stock for Class A Common Stock, our relative ownership interest in EVgo OpCo will correspondingly increase.

SELLING SECURITYHOLDERS

This prospectus relates to the possible resale by the Selling Securityholders of up to 200,747,717 shares of our Class A Common Stock and 3,148,569 Private Placement Warrants. The PIPE Investors acquired shares of Class A Common Stock pursuant to separate subscription agreements entered into and effective as of January 21, 2021 (the "Subscription Agreements"). Climate Change Crisis Real Impact I Acquisition Holdings, LLC, a Delaware limited liability company (the "Sponsor"), acquired shares of Class A Common Stock and Private Placement Warrants exercisable for shares of Class A Common Stock concurrently with our IPO (including shares converted from Class B Common Stock held by initial stockholders (the "initial stockholders") of CRIS (the "Founder Shares") into Class A Common Stock in connection with the Business Combination). Mary Powell, Richard, L. Kauffman, Mimi Alemayehou, Anne Frank-Shapiro, Daniel Gross, Amir Mehr and Stephen Moch, our former directors, each acquired Founder Shares in connection with the Company's IPO, which shares converted into Class A Common Stock at the Closing. Following the Closing, the Company is organized in an "Up-C" structure with EVgo Holdings holding 195,800,000 units in EVgo OpCo (the "EVgo OpCo Units") and an equal number of shares of Class B Common Stock. See "Redemption of OpCo Units and Class B Common Stock."

When we refer to the "Selling Securityholders" in this prospectus, we mean the persons listed in the table below, and the pledgees, donees, or other transferees who later come to hold any of the Class A Common Stock or Private Placement Warrants other than through a public sale, including through a distribution by such Selling Securityholders to their members.

The following table is prepared based on information provided to us by the Selling Securityholders. It sets forth the name and address of the Selling Securityholders, the aggregate number of shares of Class A Common Stock and Private Placement Warrants that the Selling Securityholders may offer pursuant to this prospectus, and the beneficial ownership of the Selling Securityholders both before and after the offering. We have based percentage ownership prior to this offering on 69,078,584 shares of Class A Common Stock, 195,800,000 shares of Class B Common Stock and 3,148,569 Private Placement Warrants outstanding, in each case as of August 1, 2022. In calculating percentages of shares of Class A Common Stock owned by a particular Selling Securityholder, we treated as outstanding the number of shares of our Class A Common Stock issuable upon exercise of that particular Selling Securityholder's Private Placement Warrants, if any, and did not assume the exercise of any other Selling Securityholder's Private Placement Warrants.

We cannot advise you as to whether the Selling Securityholders will in fact sell any or all of such Class A Common Stock or Private Placement Warrants. In addition, the Selling Securityholders may sell, transfer or otherwise dispose of, at any time and from time to time, the Class A Common Stock and Private Placement Warrants in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus. For purposes of this table, we have assumed that the Selling Securityholders will have sold all of the securities covered by this prospectus upon the completion of the offering.

The letter agreement entered into concurrently with the Business Combination Agreement by and among CRIS, certain co-investors, the Sponsor and the other initial stockholders contains provisions that subject 718,750 Founder Shares held by the initial stockholders to forfeitures if shares of Class A Common Stock do not trade at a volume weighted average price per share equal to or greater than $15.00 for 20 out of 30 consecutive trading days within the five years following the Closing.

PLAN OF DISTRIBUTION

We are registering shares of Class A Common Stock and Preferred Stock that may be offered from time to time in amounts, at prices and on terms to be determined by market conditions and other factors at the time of the offering. Additionally, we are registering the issuance by us of up to 3,148,569 shares of our Class A Common Stock issuable upon the exercise of the Private Placement Warrants and 14,948,551 shares of our Class A Common Stock issuable upon the exercise of the Public Warrants. We are also registering the resale by the Selling Securityholders of up to 3,148,569 Private Placement Warrants and 200,747,717 shares of our Class A Common Stock. Such shares include all shares of Class A Common Stock held by the Selling Securityholders, shares of Class A Common Stock issuable upon exercise of the Private Placement Warrants, shares of Class A Common Stock issuable upon the redemption of OpCo Units, together with an equal number of shares of Class B Common Stock, and PIPE Shares. The Selling Securityholders may offer and sell, from time to time, their respective shares of Class A Common Stock and Private Placement Warrants covered by this prospectus.

We are required to pay all fees and expenses incident to the registration of the shares of our Class A Common Stock, Preferred Stock and Private Placement Warrants to be offered and sold pursuant to this prospectus. The Selling Securityholders will bear all discounts and commissions and discounts, if any, attributable to their sale of shares of our Class A Common Stock or Private Placement Warrants.

We will not receive any of the proceeds from the sale of the securities by the Selling Securityholders. We will receive proceeds from Warrants exercised in the event that such Warrants are exercised for cash. The aggregate proceeds to the Selling Securityholders will be the purchase price of the securities less any discounts and commissions borne by the Selling Securityholders. The term "Selling Securityholders" includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer. The Selling Securityholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The Selling Securityholders may sell their shares of Class A Common Stock or Private Placement Warrants by one or more of, or a combination of, the following methods:

•

underwritten transactions (whether on a firm commitment or best efforts basis, including through bought deals);

​

•

exchange distributions and/or secondary distributions;

​

•

sales directly to one or more purchasers;

​

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

​

•

through the distribution of securities by a Selling Securityholder to its partners, members or stockholders;

​

•

short sales and delivery of the shares of Class A Common Stock to close out short positions enter into after the effective date of this registration statement;

​

​

•

sales on the Nasdaq or on any national securities exchange or quotation service on which our Class A Common Stock may be listed or quoted at the time of the sale;

​

•

through trading plans entered into by a Selling Securityholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

​

•

sales through agents or to or through underwriters or broker-dealers;

​

•

in "at the market" offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

​

•

in privately negotiated transactions;

​

•

in options transactions;

​

•

through a combination of any of the above methods of sale; or

​

•

​

In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

Additionally, the Selling Securityholders may elect to make an in-kind distribution of their shares of Class A Common Stock and Private Placement Warrants to their respective members, partners or stockholders. To the extent that such members, partners or stockholders are not affiliates or ours, such members, partners of stockholders would thereby receive freely tradable securities pursuant to the distribution through this registration statement. The Selling Securityholders also may transfer their shares of Class A Common Stock and Private Placement Warrants in other circumstances, in which case the transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

This prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the shares or otherwise, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of shares of Class A Common Stock in the course of hedging the positions they assume with Selling Securityholders. The Selling Securityholders may also sell shares of Class A Common Stock short and redeliver the shares to close out such short positions. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Securityholders may also pledge shares to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

A Selling Securityholder may fix a price or prices of our Class A Common Stock at:

•

market prices prevailing at the time of any sale under this registration statement;

​

•

prices related to market prices; and

​

•

negotiated prices.

​

A Selling Securityholder may change the price of the Class A Common Stock offered from time to time.

A Selling Securityholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If an applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any Selling Securityholder or borrowed from any Selling Securityholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities

received from any Selling Securityholder in settlement of those derivatives to close out any related open borrowings of stock. If applicable through securities laws, the third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any Selling Securityholder may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

At the time a particular offer of securities is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public. If a Selling Securityholder uses underwriters in an offering, it will execute an underwriting agreement with such underwriters. If a Selling Securityholder uses an underwriting syndicate, the managing underwriter(s) will be specified on the cover of the prospectus supplement. If a Selling Securityholder uses underwriters for a sale of Class A Common Stock, the underwriters will acquire the shares for their own accounts. The underwriters may resell the Class A Common Stock from time to time in one or more transactions, including negotiated transactions, at a fixed offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedents and the underwriters will be obligated to purchase all of the offered securities if any are purchased.

In effecting sales, broker-dealers or agents engaged by the Selling Securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Securityholders in amounts to be negotiated immediately prior to the sale.

In offering the securities covered by this prospectus, the Selling Securityholders and any broker-dealers or agents who execute sales for the Selling Securityholders may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling Securityholders and the compensation of any broker-dealer or agent may be deemed to be underwriting discounts and commissions. Any underwriters, broker-dealers or agents will be identified in the applicable prospectus supplement and their compensation will be described. A Selling Securityholder may enter into agreements with the underwriters, broker-dealers and agents to indemnify them against specified civil liabilities, including liabilities under the Securities Act.

Underwriters, broker-dealers or agents and their associates may engage in other transactions with and perform other services for us in the ordinary course of business.

If so indicated in a prospectus supplement, a Selling Securityholder will authorize underwriters or other persons acting as such Selling Securityholder's agents to solicit offers by institutional investors to purchase shares of Class A Common Stock pursuant to contracts providing for payment and delivery on a future date. A Selling Securityholder may enter contracts with commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutional investors. The obligations of any institutional investor will be subject to the condition that its purchase of the offered securities will not be illegal at the time of delivery. The underwriters and other agents will not be responsible for the validity or performance of contracts.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the Selling Securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of securities in the market and to the activities of the Selling Securityholders and their affiliates. In addition, we will make copies of this prospectus available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

The Selling Securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

A holder of Warrants may exercise its Warrants in accordance with the Warrant Agreement on or before the expiration date set forth therein by surrendering, at the office of the warrant agent, Continental Stock Transfer & Trust Company, the certificate evidencing such Warrants, with the form of election to purchase set forth thereon, properly completed and duly executed, accompanied by full payment of the exercise price and any and all applicable taxes due in connection with the exercise of the Warrants, subject to any applicable provisions relating to cashless exercises in accordance with the Warrant Agreement.

The specific terms of any lock-up provisions in respect of any given offering will be described in any applicable prospectus supplement.

The Board of Directors is able, without stockholder approval, to issue Preferred Stock with voting and other rights that could adversely affect the voting power and other rights of holders of common stock and could have anti-takeover effects. The ability of the Board of Directors to issue Preferred Stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control or the removal of existing management. The Company has no shares of Preferred Stock outstanding at the date hereof.

Redeemable Warrants

Public Warrants

Each whole warrant entitles the registered holder to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment as discussed below. Pursuant to the Warrant Agreement, a warrant holder may exercise its warrants only for a whole number of shares of Class A Common Stock. This means that only a whole warrant may be exercised at any given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. Accordingly, unless you purchase at least two units, you will not be able to receive or trade a whole warrant. The warrants will expire on July 1, 2026, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company is not obligated to deliver any shares of Class A Common Stock pursuant to the exercise of a warrant and have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of Class A Common Stock underlying the warrants is then

effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations described below with respect to registration. No warrant is exercisable and the Company is not obligated to issue shares of Class A Common Stock upon exercise of a warrant unless Class A Common Stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant is not entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event is the Company required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of Class A Common Stock underlying such unit.

Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $18.00. The Company may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

•

in whole and not in part;

​

•

at a price of $0.01 per warrant;

​

•

upon a minimum of 30 days' prior written notice of redemption to each warrant holder; and

​

•

if, and only if, the last reported sale price of Class A Common Stock for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders (which the Company refers to as the "Reference Value") equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "- Anti-Dilution Adjustments").

​

The Company will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of Class A Common Stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A Common Stock is available throughout the 30-day redemption period. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

The Company has established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and the Company issues a notice of redemption of the warrants, each warrant holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. Any such exercise would not be done on a "cashless" basis and would require the exercising warrant holder to pay the exercise price for each warrant being exercised. However, the price of Class A Common Stock may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "- Anti-Dilution Adjustments") as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $10.00. Once the warrants become exercisable, EVgo may redeem the outstanding warrants:

•

in whole and not in part;

​

•

at $0.10 per warrant upon a minimum of 30 days' prior written notice of redemption, provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the "fair market value" of Class A Common Stock (as defined below in the immediately following paragraph) except as otherwise described below;

​

•

if, and only if, the Reference Value (as defined above under the heading "- Redeemable Warrants - Public Warrants - Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $18.00") equals or exceeds $10.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "- Redeemable Warrants - Public Warrants - Anti-Dilution Adjustments"); and

​

•

if the Reference Value is less than $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "- Redeemable Warrants - Public Warrants - Anti-Dilution Adjustments"), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

​

Beginning on the date the notice of redemption is given until the warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis. The numbers in the table below represent the number of shares of Class A Common Stock that a warrant holder will receive upon such cashless exercise in connection with a redemption by the Company pursuant to this redemption feature, based on the "fair market value" of Class A Common Stock on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for $0.10 per warrant), determined for these purposes based on the volume-weighted average price of Class A Common Stock as reported during the ten trading days immediately following the date on which the notice of redemption is sent to holders of warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below. The Company will provide its warrant holders with the final fair market value no later than one business day after the ten-trading day period described above ends.

The share prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a warrant or the exercise price of a warrant is adjusted as set forth under the heading "- Anti-Dilution Adjustments" below. If the number of shares issuable upon exercise of a warrant is adjusted, the adjusted share prices in the column headings will equal the share prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the exercise price of the warrant after such adjustment and the denominator of which is the price of the warrant immediately prior to such adjustment. In such an event, the number of shares in the table below shall be adjusted by multiplying such share amounts by a fraction, the numerator of which is the number of shares deliverable upon exercise of a warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a warrant as so adjusted. If the exercise price is adjusted, (a) in the case of an adjustment pursuant to the fifth paragraph under the heading "- Anti-Dilution Adjustments" below, the adjusted share prices in the column headings will equal the unadjusted share price multiplied by a fraction, the numerator of which is the higher of the market value and the newly issued price as set forth under the heading "- Anti-Dilution Adjustments" and the denominator of which is $10.00 and (b) in the case of an adjustment pursuant to the second paragraph under the heading "- Anti-Dilution Adjustments" below, the adjusted share prices in the column headings will equal the unadjusted share price less the decrease in the exercise price of a warrant pursuant to such exercise price adjustment.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of shares of Class A Common Stock to be issued for each warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the volume weighted average price of Class A Common Stock as reported during the ten trading days immediately following the date on which the notice of redemption is sent to holders of warrants is $11.00 per share, and at such time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.277 shares of Class A Common Stock for each whole warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the volume weighted average price of Class A Common Stock as reported during the ten trading days immediately following the date on which the notice of redemption is sent to holders of warrants is $13.50 per share, and at such time there are 38 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.298 shares of Class A Common Stock for each whole warrant. In no event will the warrants be exercisable on a cashless basis in connection with this redemption feature for more than 0.361 shares of Class A Common Stock per whole warrant (subject to adjustment). Finally, as reflected in the table above, if the warrants are out of the money and about to expire, they cannot be exercised on a cashless basis in connection with a redemption by the Company pursuant to this redemption feature, since they will not be exercisable for any Class A Common Stock.

This redemption feature differs from the typical warrant redemption features used in many other blank check companies, which typically only provide for a redemption of warrants for cash (other than the Private Placement Warrants) when the trading price for Class A Common Stock exceeds $18.00 per share for a specified period of time. This redemption feature is structured to allow for all of the outstanding warrants to be redeemed when Class A Common Stock are trading at or above $10.00 per share, which may be at a time when the trading price of Class A Common Stock is below the exercise price of the warrants. The Company

established this redemption feature to provide it with the flexibility to redeem the warrants without the warrants having to reach the $18.00 per share threshold set forth above under "- Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $18.00." Holders choosing to exercise their warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their warrants based on an option pricing model with a fixed volatility input as of September 29, 2020. This redemption right provides the Company with an additional mechanism by which to redeem all of the outstanding warrants, and therefore have certainty as to its capital structure as the warrants would no longer be outstanding and would have been exercised or redeemed. The Company is required to pay the applicable redemption price to warrant holders if the Company chooses to exercise this redemption right and it will allow the Company to quickly proceed with a redemption of the warrants if it determines it is in its best interest to do so. As such, the Company would redeem the warrants in this manner when it believes it is in its best interest to update its capital structure to remove the warrants and pay the redemption price to the warrant holders.

As stated above, the Company can redeem the warrants when the shares of Class A Common Stock are trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to its capital structure and cash position while providing warrant holders with the opportunity to exercise their warrants on a cashless basis for the applicable number of shares. If the Company chooses to redeem the warrants when the shares of Class A Common Stock are trading at a price below the exercise price of the warrants, this could result in the warrant holders receiving fewer shares of Class A Common Stock than they would have received if they had chosen to wait to exercise their warrants for shares of Class A Common Stock if and when such shares of Class A Common Stock were trading at a price higher than the exercise price of $11.50.

No fractional shares of Class A Common Stock will be issued upon exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, the Company will round down to the nearest whole number of the number of shares of Class A Common Stock to be issued to the holder. If, at the time of redemption, the warrants are exercisable for a security other than Class A Common Stock pursuant to the Warrant Agreement, the warrants may be exercised for such security.

Redemption Procedures. A holder of a warrant may notify the Company in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person's affiliates), to the warrant agent's actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of Class A Common Stock outstanding immediately after giving effect to such exercise.

Anti-Dilution Adjustments. If the number of outstanding shares of Class A Common Stock is increased by a stock dividend payable in shares of Class A Common Stock, or by a split-up of shares of Class A Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Class A Common Stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares of Class A Common Stock. A rights offering to holders of shares of Class A Common Stock entitling holders to purchase shares of Class A Common Stock at a price less than the historical fair market value (as defined below) will be deemed a stock dividend of a number of shares of Class A Common Stock equal to the product of (i) the number of shares of Class A Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A Common Stock) and (ii) one minus the quotient of (x) the price per share of Class A Common Stock paid in such rights offering divided by (y) the historical fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A Common Stock, in determining the price payable for Class A Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon conversion or exercise and (ii) "historical fair market value" means the volume weighted average price of Class A Common Stock as reported during the ten trading day period ending on the trading day prior to the first date on which the shares of Class A Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

If the number of outstanding shares of Class A Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Class A Common Stock or other similar

event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Class A Common Stock issuable on exercise of each warrant will be decreased in proportion to such decrease in outstanding shares of Class A Common Stock.

Whenever the number of shares of Class A Common Stock purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of Class A Common Stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Class A Common Stock so purchasable immediately thereafter.

The warrants were issued in registered form under the Warrant Agreement. On October 5, 2020, the Company filed a copy of the Warrant Agreement with the SEC as Exhibit 4.1 to its Current Report on Form 8-K. The Warrant Agreement contains a complete description of the terms and conditions applicable to the warrants. The Warrant Agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by holders of at least 50% of the then-outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to the Company, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of Class A Common Stock and any voting rights until they exercise their warrants and receive shares of Class A Common Stock. After the issuance of shares of Class A Common Stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole number of shares of Class A Common Stock to be issued to the warrant holder.

Private Placement Warrants

The Private Placement Warrants will not be redeemable by the Company (except as described above under "- Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $10.00") so long as they are held by the Sponsor or its permitted transferees. The Sponsor, or its permitted transferees, has the option to exercise the Private Placement Warrants on a cashless basis. Except as described below, the Private Placement Warrants have terms and provisions that are identical to those of the warrants sold as part of the units in the IPO, including as to exercise price, exercisability and exercise period. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by holders on the same basis as the warrants included in the units sold in the IPO.

Except as described above under "- Redemption of warrants when the price per share of Class A Common Stock equals or exceeds $10.00," if holders of the Private Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering the warrants for that number of shares of Class A Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Common Stock underlying the warrants, multiplied by the excess of the "fair market value" of the Company's Class A Common Stock over the exercise price of the warrants by (y) the fair market value. The "fair market value" shall mean the average last reported sale price of Class A Common Stock for the ten trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to holders of warrants, as applicable. The reason the Company agreed that these warrants will be exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees is because it was not known at that time whether they will be affiliated with the Company following an initial business combination. If they remain affiliated with the Company, their ability to sell the Company's securities in the open market will be significantly limited. The

Company expects to have policies in place that prohibit insiders from selling the Company's securities except during specific periods of time. Even during such periods of time when insiders will be permitted to sell the Company's securities, an insider cannot trade in the Company's securities if he or she is in possession of material non-public information. Accordingly, unlike public stockholders who could sell the shares of Class A Common Stock issuable upon exercise of the warrants freely in the open market, the insiders could be significantly restricted from doing so. As a result, the Company believes that allowing holders to exercise such warrants on a cashless basis is appropriate.

Registration Rights

In connection with the Closing, the Company, the Sponsor and the other initial stockholders terminated the existing registration rights agreement and entered into the registration rights agreement (the "Registration Rights Agreement") with EVgo Holdings (together with the Sponsor, the other initial stockholders and any person or entity who becomes a party to the Registration Rights Agreement, the "Holders") that grant certain resale registration rights with respect to (a) the Private Placement Warrants (including any shares of Class A Common Stock issued or issuable upon the exercise of any Private Placement Warrants), (b) shares of Class A Common Stock issued or issuable upon conversion of any Founder Shares, (c) any outstanding shares of Class A Common Stock held by a Holder as of the date of the Registration Rights Agreement, (d) any shares of Class A Common Stock issued or issuable upon exchange of OpCo Units and shares of Class B Common Stock held by a Holder as of the date of the Registration Rights Agreement, and (e) any other equity security of the Company issued or issuable with respect to the registrable securities, subject to the terms and conditions set forth in the Registration Rights Agreement.

Pursuant to the Registration Rights Agreement, the Company filed a registration statement on Form S-1, originally filed with the SEC on July 20, 2021 (File Number 333-258052) (the "Registration Statement"), registering the resale of the registrable securities permitted to be registered for resale from time to time pursuant to the applicable rules and regulations under the Securities Act. The Registration Statement was declared effective on July 30, 2021. The Company will use its reasonable best efforts to cause the Registration Statement to remain effective, in accordance with the Registration Rights Agreement. The Registration Rights Agreement also provides holders with certain customary demand and piggyback registration rights. The Company has filed the Registration Statement to satisfy such obligations. Additionally, the Company agreed that, as soon as reasonably practicable after it is eligible to register holders' securities on a registration statement on Form S-3, the Company will file a new registration statement with the SEC (at its sole cost and expense), and the Company will use its reasonable best efforts to cause such new registration statement to become effective and remain effective, in accordance with the Registration Rights Agreement. The registration statement of which this prospectus forms a part is being filed to satisfy such obligation.

Pursuant to Subscription Agreements effective as of January 21, 2021 entered into with a number of purchasers to purchase from the Company a total of 40,000,000 PIPE Shares, the Company agreed to file with the SEC (at its sole cost and expense) a registration statement registering the resale of the PIPE Shares, and the Company agreed to use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof. The Registration Statement initially filed on July 20, 2021 and declared effective on July 30, 2021 included the PIPE Shares.

Certain Anti-Takeover Provisions of Delaware Law, the Company's Charter and Bylaws

The Company's Charter provides that it opted out of Section 203 of the Delaware General Corporation Law (the "DGCL"). However, the Company's Charter contains similar provisions providing that it may not engage in certain "business combinations" with any "interested stockholder" for a three-year period following the time that the stockholder became an interested stockholder, unless:

•

prior to such time, the Board of Directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

​

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the Company's voting stock outstanding at the time the transaction commenced, excluding certain shares; or

​

•

at or subsequent to that time, the business combination was approved by the Board of Directors and by the affirmative vote of holders of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

​

Generally, a "business combination" includes a merger, asset or stock sale or certain other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who, together with that person's affiliates and associates, owns, or within the previous three years owned, 15% or more of the Company's voting stock.

Under certain circumstances, this provision will make it more difficult for a person who would be an "interested stockholder" to effect various business combinations with a corporation for a three-year period. This provision may encourage companies interested in acquiring the Company to negotiate in advance with the Board of Directors because the stockholder approval requirement would be avoided if the Board of Directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in the Board of Directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

The Company's Charter provides that LS Power (as defined in the Company's Charter) and its affiliates, any of its respective direct or indirect transferees who hold at least 15% of the Company's outstanding common stock after such transfer and any group as to which such persons are party to, do not constitute "interested stockholders" for purposes of this provision.

The Company's authorized but unissued common stock and Preferred Stock will be available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and Preferred Stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.
