Ladies and Gentlemen:

We have acted as counsel to EVgo Inc., a Delaware corporation (the “Company”), and you have requested our opinion in connection with the filing of a Registration Statement on Form S-1 (the “Registration Statement”) with the Securities and Exchange Commission, including a related prospectus filed with the Registration Statement (the “Prospectus”), covering the registration of (a) the issuance of shares of Class A Common Stock, $0.0001 par value per share (“Class A Common Stock”), of the Company upon the exercise of warrants issued by the Company, and (b) the resale of Class A Common Stock and warrants issued by the Company held by certain stockholders and holders of outstanding warrants of the Company, as follows:

(i) the issuance of 6,600,000 shares (the “Private Warrant Shares”) of Class A Common Stock upon the exercise of certain outstanding warrants (the “Private Warrants”);

(ii) the issuance of 11,499,988 shares (the “Public Warrant Shares” and, together with the Private Warrant Shares, the “Warrant Shares”) of Class A Common Stock upon the exercise of certain outstanding warrants (the “Public Warrants” and, together with the Private Warrants, the “Warrants”);

(iii) the resale of 6,600,000 Private Warrants (the “Resale Warrants”); and

(iv) the resale of 52,350,000 shares of Class A Common Stock (including up to 6,600,000 Private Warrant Shares) (the “Selling Stockholder Shares”).

All of the Resale Warrants and Selling Stockholder Shares are being registered on behalf of certain selling securityholders of the Company (the “Selling Securityholders”).The Private Warrants and the Public Warrants were issued pursuant to a Warrant Agreement, dated September 29, 2020, between the Company and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (“Warrant Agreement”).

In connection with this opinion, we have examined and relied upon the Registration Statement, the Prospectus, the Company’s certificate of incorporation and bylaws, each as currently in effect, the Warrant Agreement and the originals, or copies identified to our satisfaction, of such corporate records of the Company, certificates of public officials, officers of the Company, and other persons, and such other documents, agreements and instruments as we have deemed relevant and necessary for the basis of our opinions hereinafter expressed. In such examination, we have assumed the following: (a) the authenticity of original documents and the genuineness of all signatures; (b) the conformity to the originals of all documents submitted to us as copies; and (c) the truth, accuracy, and completeness of the information, representations, and warranties contained in the records, documents, instruments, and certificates we have reviewed.

With respect to the Warrants and the Warrant Shares, we express no opinion to the extent that, notwithstanding the Company’s current reservation of shares of Class A Common Stock, future issuances of securities of the Company, including the Warrant Shares, and/or antidilution adjustments to outstanding securities of the Company, including the Warrants, may cause the Warrants to be exercisable for more shares of Class A Common Stock than the number that then remain authorized but unissued. Further, we have assumed the Exercise Price (as defined in the Warrants) will not be adjusted to an amount below the par value per share of the shares of Class A Common Stock.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that:

1. The Resale Warrants to be sold by the Selling Securityholders pursuant to the Registration Statement constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement may be limited by applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium and other laws relating to or affecting creditors’ rights generally and to general equitable or public policy principles (regardless of whether enforcement is sought in a proceeding in equity or at law).

2. The Warrant Shares, when issued and paid for upon exercise of the Warrants in accordance with the terms of the Warrants, will be validly issued, fully paid and nonassessable.

3. The Selling Stockholder Shares have been duly authorized and are, or in the case of any Selling Stockholder Shares subject to stock warrants, when issued in accordance with their terms, validly issued, fully paid and nonassessable.

We express no opinion as to any provision of the Warrants that: (i) provides for economic remedies to the extent such provisions may constitute unlawful penalties, (ii) relates to advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitations, trial by jury, or procedural rights, (iii) restricts non-written modifications and waivers, (iv) provides for the payment of legal and other professional fees where such payment is contrary to law or public policy, (v) relates to exclusivity, election or accumulation of rights or remedies, (vi) authorizes or validates conclusive or discretionary determinations, or (vii) provides that provisions of the Warrants are severable to the extent an essential part of the agreed exchange is determined to be invalid and unenforceable.
