EXPLANATORY NOTE

Chevron Corporation (“we”, “Chevron” or the “Company”) hereby amends its original registration statement on Form S-4 (File No. 333-272776) filed with the Securities and Exchange Commission (the “Commission”) on June 20, 2023, as amended by the pre-effective Amendment No. 1 thereto filed with the Commission on June 29, 2023 and the pre-effective Amendment No. 2 thereto filed with the Commission on July 5, 2023 (the “Form S-4”), which the Commission declared effective at 5:00 p.m. Eastern Time on July 7, 2023, by filing this post-effective Amendment No. 1 on Form S-8 (this “Post-Effective Amendment” and together with the Form S-4, this “Registration Statement”).

The Company filed the Form S-4 in connection with the merger contemplated by the Agreement and Plan of Merger, dated as of May 21, 2023 (the “Merger Agreement”) by and among the Company, Bronco Merger Sub Inc., a direct, wholly owned subsidiary of the Company (“Merger Subsidiary”) and PDC Energy, Inc. (“PDC”), pursuant to which, effective as of August 7, 2023, Merger Subsidiary merged with and into PDC (the “Merger”), and PDC continued as the surviving corporation and a direct, wholly owned subsidiary of the Company.

As a result of the Merger, each issued and outstanding share of PDC common stock, par value $0.01 per share (“PDC common stock”), was converted automatically into 0.4638 shares (the “Exchange Ratio”) of Chevron common stock, par value $0.75 per share (“Chevron common stock”).

Pursuant to the terms of the Merger Agreement, certain outstanding stock appreciation rights and restricted stock unit awards, in each case with respect to PDC common stock, were converted into corresponding stock appreciation rights and restricted stock unit awards, respectively, with respect to Chevron common stock. In addition, certain outstanding performance stock unit awards with respect to PDC common stock were converted into corresponding restricted stock unit awards with respect to a fixed number of shares of Chevron common stock determined based on actual performance. In each case, the number of shares underlying the respective awards was adjusted based on the Exchange Ratio.

The Company hereby amends the Form S-4 by filing this Post-Effective Amendment relating to 858,286 shares of Chevron common stock issuable pursuant to the PDC Energy, Inc. 2018 Equity Incentive Plan and the PDC Energy, Inc. Amended and Restated 2010 Long-Term Equity Compensation Plan. All such shares were previously registered on the Form S-4 but will be subject to issuance pursuant to this Post-Effective Amendment.

Item 5. Interests of Named Experts and Counsel.

The legality of the securities offered pursuant to this Registration Statement has been passed on by Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York, New York.

Item 6. Indemnification of Directors and Officers.

Section 145(a) of the General Corporation Law of the State of Delaware (the “DGCL”) provides, in general, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, because the person is or was a director or officer of the corporation. Such indemnity may be against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and if, with respect to any criminal action or proceeding, the person did not have reasonable cause to believe the person’s conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director or officer of the corporation, against any expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses that the Court of Chancery or such other court shall deem proper.

Section 145(g) of the DGCL provides, in general, that a corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation against any liability asserted against the person in any such capacity, or arising out of the person’s status as such, whether or not the corporation would have the power to indemnify the person against such liability under the provisions of the law. Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by applicable law, a director will not be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director. In addition, our amended and restated certificate of incorporation provides that we will indemnify each director and officer and may indemnify employees and agents, as determined by our board, to the fullest extent provided by the laws of the State of Delaware.

Both Article VIII of Chevron’s certificate of incorporation, as amended (“Chevron’s certificate of incorporation”) and Article VIII of Chevron’s by-laws, as amended (“Chevron’s By-Laws” and, together with Chevron’s certificate of incorporation, “Chevron’s organizational documents”) provide for indemnification of its directors, officers, employees and other agents and any person serving or having served, at the request of the corporation, as a director, officer, manager, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust or other organization or enterprise, nonprofit or otherwise, including an employee benefit plan (“corporate servant” or “indemnified person”). Chevron’s organizational documents provide that, to the fullest extent permitted by the DGCL and without limiting any rights of indemnified persons, Chevron shall indemnify any corporate servant who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or administrative (“proceedings”), by reason of the fact that the person is or was a corporate servant against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the corporate servant. Chevron’s certificate of incorporation provides that Chevron’s board of directors is authorized, to the extent permitted by the DGCL, to cause the corporation to pay expenses incurred by corporate servants in defending proceedings and to purchase and maintain insurance on their behalf whether or not the corporation would have the power to indemnify them under the provisions of Article VIII of the certificate of incorporation or otherwise. Chevron’s By-Laws provide that Chevron shall pay expenses (including attorney’s fees) by an indemnified person who is a current or former director, officer or employee of Chevron in defending any such proceeding in advance of its final disposition; provided, however, that the advancement of expenses shall be made only upon delivery of an undertaking to Chevron, by or on behalf of such indemnified person, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnified person is not entitled to be indemnified for such expenses under Chevron’s By-laws or otherwise. All of the above rights are not exclusive of any other right to which any indemnified person may otherwise be entitled.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such a provision may not eliminate or limit the liability of (i) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director under § 174 of the DGCL regarding liability for unlawful dividends or stock repurchases and redemptions, (iv) a director or officer for any transaction from which the director or officer derived an improper personal benefit or (v) an officer in any action by or in the right of the corporation. Chevron’s certificate of incorporation provides for such limitation of liability in the case of Chevron directors, but does not limit the liability of Chevron officers.

The directors and officers of Chevron are covered by policies of insurance under which they are insured, within limits and subject to limitations, against certain expenses not indemnifiable by Chevron in connection with the defense of actions, suits or proceedings, and certain liabilities not indemnifiable by Chevron that might be imposed as a result of such actions, suits or proceedings, in which they are parties by reason of being or having been directors or officers.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement; provided

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act), that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

San Ramon, CA 94583

Post-Effective Amendment on Form S-8 to Form S-4

Ladies and Gentlemen:

We have acted as special counsel to Chevron Corporation, a Delaware corporation (the “Company”), in connection with the Post-Effective Amendment on Form S-8 to Form S-4 (the “Registration Statement”) of the Company, filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Act”), and the rules and regulations thereunder (the “Rules”). You have asked us to furnish our opinion as to the legality of the securities being registered under the Registration Statement. The Registration Statement relates to the registration under the Act of 858,286 shares of the Company’s common stock, par value $.75 per share (the “Shares”), issuable in respect of awards to be granted under the PDC Energy, Inc. 2018 Equity Incentive Plan and the PDC Energy, Inc. Amended and Restated 2010 Long-Term Equity Compensation Plan (as amended and restated, the “Plans”).

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (collectively, the “Documents”):

In addition, we have examined (i) such corporate records of the Company that we have considered appropriate, including a copy of the certificate of incorporation, as amended and restated, and the by-laws, as amended and restated, of the Company, certified by the Company as in effect on the date of this letter, and copies of resolutions of the board of directors of the Company relating to the issuance of the Shares, certified by the Company, and (ii) such other certificates, agreements and documents that we deemed relevant and necessary as a basis for the opinion expressed below. We have also relied upon certificates of public officials and the officers of the Company.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of all such agreements and documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that the Shares have been duly authorized by all necessary corporate action on the part of the Company and, when issued, delivered and paid for in accordance with the terms of the Plans and any applicable Agreement under the Plans, the Shares will be validly issued, fully paid and non-assessable.

The opinion expressed above is limited to the General Corporation Law of the State of Delaware. Our opinion is rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required by the Act or the Rules.
