PRELIMINARY, SUBJECT TO COMPLETION, DATED JUNE 20, 2023

TRANSACTION PROPOSED-YOUR VOTE IS VERY IMPORTANT

Dear Stockholders of PDC Energy, Inc.:

On May 21, 2023, PDC Energy, Inc. (“PDC”), Chevron Corporation (“Chevron”) and Bronco Merger Sub Inc., a direct, wholly-owned subsidiary of Chevron (“Merger Subsidiary”), entered into a merger agreement under which, upon the terms and subject to the conditions set forth therein, Merger Subsidiary will merge with and into PDC, with PDC surviving as a direct, wholly-owned subsidiary of Chevron (the “merger”). If the merger is completed, PDC stockholders will receive, in exchange for each share of PDC common stock held immediately prior to the merger, 0.4638 of a share of Chevron common stock. The PDC Board of Directors (the “PDC Board”) has unanimously approved the merger agreement and recommends that PDC stockholders vote in favor of adopting the merger agreement.

Based on Chevron’s closing stock price on [    ], 2023, the most recent practicable date for which such information was available, the merger consideration represented approximately $[            ] in value per share of PDC common stock, which represents a premium of approximately [    ]% over PDC’s closing stock price on May 19, 2023, the last trading day before the public announcement of the execution of the merger agreement with Chevron. The value of the merger consideration to be received in exchange for each share of PDC common stock will fluctuate with the market value of Chevron common stock until the transaction is complete. The common stock of PDC is listed on the Nasdaq Global Select Market under the symbol “PDCE”. The common stock of Chevron is listed on the New York Stock Exchange under the symbol “CVX”. Upon completion of the merger, former PDC stockholders are expected to own approximately [    ]% of the then outstanding Chevron common stock, based on Chevron’s outstanding equity as of [    ], 2023.

The merger cannot be completed without approval of the proposal to adopt the merger agreement by the affirmative vote of holders of a majority of the outstanding shares of PDC common stock entitled to vote thereon. Because of this, PDC is holding a special meeting of its stockholders on [    ], 2023 to vote on the proposal necessary to complete the merger. Information about the meeting, the merger, the merger agreement, and the other business to be considered by stockholders at the special meeting is contained in this proxy statement/prospectus. The PDC Board has fixed the close of business on [    ], 2023 as the record date for the determination of PDC stockholders entitled to notice of, and to vote at, the special meeting. Any stockholder entitled to attend and vote at the special meeting is entitled to appoint a proxy to attend and vote on such stockholder’s behalf. Such proxy need not be a holder of PDC common stock. We urge you to read this proxy statement/prospectus and the annexes and documents incorporated by reference carefully. You should also carefully consider the risks that are described in the “Risk Factors” section beginning on page [    ].

The PDC Board has unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to and in the best interests of the PDC stockholders, approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger, and directed that the merger agreement be submitted to the PDC stockholders for adoption at a meeting of such stockholders, and unanimously recommends that PDC stockholders vote “FOR” the proposal to approve and adopt the merger agreement and the transactions contemplated thereby, including the merger.

Your vote is very important regardless of the number of shares of PDC common stock that you own.

Whether or not you plan to attend the special meeting, please submit your proxy as soon as possible by following the instructions on the accompanying proxy card to make sure that your shares are represented at the meeting. If your shares are held in the name of a broker, bank or other nominee, please follow the instructions on the voting instruction form furnished by the broker, bank or other nominee. You must provide voting instructions by filling out the voting instruction form in order for your shares to be voted.

The special meeting will be held in a virtual meeting format only. You will not be able to attend the special meeting physically in person.

Thank you for your continued support, interest and investment in PDC.

Very truly yours,

Barton R. Brookman

President and Chief Executive Officer

The PDC Board has unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to and in the best interests of the PDC stockholders, approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger, and directed that the merger agreement be submitted to the PDC stockholders for adoption at a meeting of such stockholders and unanimously recommends that PDC stockholders vote “FOR” the merger proposal, “FOR” the merger-related compensation proposal and “FOR” the adjournment proposal.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following questions and answers briefly address some commonly asked questions about the merger and the special meeting of PDC stockholders (the “special meeting”). They may not include all of the information that is important to stockholders of PDC. PDC stockholders should carefully read this entire proxy statement/prospectus, including the annexes and the other documents referred to or incorporated by reference in this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page [    ] of this proxy statement/prospectus.

Q: What is the merger?

Chevron Corporation (“Chevron”), Bronco Merger Sub Inc., a direct, wholly-owned subsidiary of Chevron (“Merger Subsidiary”), and PDC Energy, Inc. (“PDC”) have entered into an Agreement and Plan of Merger, dated as of May 21, 2023 (as it may be amended from time to time, the “merger agreement”). A copy of the merger agreement is attached as Annex A to this proxy statement/prospectus. The merger agreement contains the terms and conditions of the proposed acquisition of PDC by Chevron. Under the merger agreement, subject to satisfaction (or, to the extent permitted by law and in accordance with the merger agreement, waiver) of the conditions to the merger set forth in the merger agreement and described in this proxy statement/prospectus, Merger Subsidiary will merge with and into PDC, with PDC continuing as the surviving corporation and a direct, wholly-owned subsidiary of Chevron (the “merger” or the “transaction”).

As a result of the merger, PDC will become a direct, wholly-owned subsidiary of Chevron and will no longer be a publicly held company. Following the merger, PDC common stock will be delisted from the Nasdaq Global Select Market (“Nasdaq”) and will be deregistered under the Exchange Act, after which PDC will no longer be required under SEC rules and regulations to file periodic reports with the SEC in respect of PDC common stock.

Q: Why am I receiving these materials?

Chevron and PDC are sending these materials to PDC stockholders to help them decide how to vote their shares of PDC common stock with respect to the merger and other matters to be considered at the special meeting.

The merger cannot be completed unless PDC stockholders adopt the merger agreement with the affirmative vote of the holders of a majority of the outstanding shares of PDC common stock entitled to vote thereon. PDC is holding a special meeting of its stockholders to vote on the proposal to adopt the merger agreement and other related proposals. Information about this special meeting, the merger and the other business to be considered by stockholders at the special meeting is contained in this proxy statement/prospectus.

This proxy statement/prospectus constitutes both a proxy statement of PDC and a prospectus of Chevron. It is a proxy statement because the board of directors of PDC (the “PDC Board”) is soliciting proxies from its stockholders. It is a prospectus because Chevron will issue shares of its common stock in exchange for outstanding shares of PDC common stock in the merger.

Q: What will PDC stockholders receive in the merger?

In the merger, PDC stockholders will receive 0.4638 (the “exchange ratio”) of a validly issued, fully paid and non-assessable share of Chevron common stock (the “merger consideration”) for each share of PDC common stock (other than shares of PDC common stock held by Chevron, PDC, or Merger Subsidiary (“cancelled shares”)). This exchange ratio is fixed and will not be adjusted to reflect changes in the stock price of either company before the merger is complete. The exchange ratio will, however, be adjusted appropriately to fully reflect the effect of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon, with respect to outstanding shares of capital stock of either Chevron or PDC with a record date between the date of the merger agreement and the completion of the merger. No

1

fractional shares of Chevron common stock will be issued in connection with the merger. Each holder of PDC common stock that otherwise would have been entitled to receive a fractional share of Chevron common stock immediately prior to the effective time of the merger will have the right to receive an amount in cash, without interest, rounded to the nearest cent, in lieu of such fractional share. The value of such cash payment will be calculated by the exchange agent and will represent the holder’s proportionate interest in a trust of proceeds established from the open-market sale of that number of shares of Chevron common stock equal to the excess of (x) the aggregate number of shares of Chevron common stock to be delivered to the exchange agent by Chevron pursuant to the terms of the merger agreement over (y) the aggregate number of whole shares of Chevron common stock to be distributed to the holders of certificates or book-entry shares previously representing any such shares of PDC common stock pursuant to the merger agreement. Chevron stockholders will continue to own their existing shares of Chevron common stock, the form of which will not be changed by the transaction. For more details on the merger consideration, see “The Merger Agreement—Merger Consideration” beginning on page [    ].

Q: What equity stake will PDC stockholders hold in Chevron immediately following the merger?

Upon the completion of the merger, based on the exchange ratio, the estimated number of shares of Chevron common stock issuable as the merger consideration is approximately [                ] million shares, which will result in former PDC stockholders holding approximately [    ]% of the outstanding fully diluted Chevron common stock based on the number of outstanding shares of common stock and outstanding stock-based awards of Chevron and PDC as of [                ], 2023, the most recent practicable date for which such information was available.

For more details on the merger consideration and the treatment of PDC equity awards, see “The Merger Agreement—Merger Consideration” beginning on page [    ] and “The Merger Agreement—Merger Consideration—Treatment of PDC Equity Awards” beginning on page [    ], respectively.

Q: When do PDC and Chevron expect to complete the merger?

Chevron and PDC are working to complete the merger as soon as practicable and currently expect that the transaction will be completed by year-end 2023. Neither Chevron nor PDC can predict, however, the actual date on which the transaction will be completed because it is subject to conditions beyond each company’s control. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page [    ].

Q: Is Chevron’s obligation to complete the merger subject to Chevron receiving financing?

No. Chevron’s obligations under the merger agreement are not subject to any condition regarding its ability to finance, or obtain financing for, the merger.

Q: What happens if the merger is not completed?

If the merger agreement is not adopted by PDC stockholders or if the merger is not completed for any other reason, PDC stockholders will not receive any consideration for their shares of PDC common stock. Instead, PDC will remain an independent public company, PDC common stock will continue to be listed and traded on Nasdaq and registered under the Exchange Act and PDC will continue to file periodic reports with the SEC. Under specific circumstances, PDC may be required to pay Chevron a termination fee of $225,000,000. See “The Merger Agreement—Termination of the Merger Agreement” beginning on page [    ].

Q: Will the shares of Chevron common stock I acquire in the merger receive a dividend?

After the closing of the merger, as a holder of Chevron common stock, you will receive the same dividends on shares of Chevron common stock that all other holders of shares of Chevron common stock will receive with any dividend record date that occurs after the closing of the merger.

2

Q: Will I continue to receive dividends in respect of my shares of PDC common stock?

Prior to the closing of the merger, PDC and Chevron will coordinate regarding the declaration and payment of dividends in respect of their common stock and the record dates and payment dates relating thereto, so as to ensure that you do not receive two dividends, or fail to receive one dividend, in any quarter with respect to your shares of PDC common stock and the Chevron common stock that you receive in exchange therefor in the merger.

After the closing of the merger, former PDC stockholders who hold PDC share certificates will not be entitled to be paid dividends otherwise payable on the shares of Chevron common stock into which their shares of PDC common stock are exchangeable until they surrender their PDC share certificates according to the instructions provided to them. Dividends will be accrued for these stockholders and they will receive the accrued dividends when they surrender their PDC share certificates.

After the closing of the merger, all Chevron dividends will remain subject to approval by Chevron’s board of directors (the “Chevron Board”).

Q: What am I being asked to vote on, and why is this approval necessary?

PDC stockholders are being asked to vote on the following proposals:

Approval of the merger proposal by the affirmative vote of holders of a majority of the outstanding shares of PDC common stock entitled to vote thereon is required for completion of the merger. The completion of the merger is not conditioned on the approval of the merger-related compensation proposal or the adjournment proposal.

Q: What vote is required to approve each proposal at the special meeting?

The merger proposal: The affirmative vote of holders of a majority of the outstanding shares of PDC common stock entitled to vote thereon is required to approve the merger proposal (the “PDC stockholder approval”).

The merger-related compensation proposal: The affirmative vote of holders of a majority of the outstanding shares of PDC common stock present in person or represented by proxy at the special meeting and entitled to vote thereon is required to approve the advisory (non-binding) merger-related compensation proposal. Because the vote on the merger-related compensation proposal is advisory only, it will not be binding on either PDC or Chevron. Accordingly, if the merger agreement is adopted and the merger is completed, the merger-related compensation will be payable to PDC’s named executive officers, subject only to the conditions applicable thereto, regardless of the outcome of the non-binding, advisory vote of PDC’s stockholders.

The adjournment proposal: The affirmative vote of the holders of a majority of the outstanding shares of PDC common stock, present in person or represented by proxy at the special meeting and entitled to vote thereon is required to approve the adjournment proposal. If PDC stockholders approve the adjournment proposal, subject to

3

the terms of the merger agreement, PDC could adjourn the special meeting and use the additional time to solicit additional proxies, including soliciting proxies from PDC stockholders who have previously voted. PDC does not intend to call a vote on the adjournment proposal if the merger proposal is approved at the special meeting.

Q: What happens if the non-binding, advisory merger-related compensation proposal is not approved?

Because the vote on the merger-related compensation proposal is advisory only, it will not be binding on either PDC or Chevron. Accordingly, if the merger agreement is adopted and the merger is completed, the merger-related compensation will be payable to PDC’s named executive officers, subject only to the conditions applicable thereto, regardless of the outcome of the non-binding, advisory vote of PDC’s stockholders.

Q: What constitutes a quorum?

The presence at the special meeting, in person or by proxy, of the holders of a majority of the outstanding shares of PDC common stock entitled to vote at the special meeting will constitute a quorum for the transaction of business at the special meeting. Virtual attendance at the special meeting will constitute presence in person for the purpose of determining the presence of a quorum for the transaction of business at the special meeting. Abstentions will count as votes present and entitled to vote for the purpose of determining the presence of a quorum for the transaction of business at the special meeting. Brokers, banks or other nominees that hold shares for beneficial owners do not have discretionary authority to vote the shares as to any matter at the meeting without receiving voting instructions from the beneficial owners. Such shares will be considered to be broker non-votes and will not be counted as present for quorum purposes.

A quorum is necessary to transact business at the special meeting. PDC’s Bylaws provide that if a quorum fails to attend any meeting, the chairman of the meeting or a majority of the stockholders who are present in person or by proxy and entitled to vote at the special meeting may adjourn the meeting from time to time, without notice other than by announcement at the meeting, to another date, place, if any, and time until a quorum is present. If the adjournment is for more than 30 days or if after the adjournment, a new record date is fixed for the adjourned meeting, PDC will provide a notice of the adjourned meeting to each stockholder of record entitled to vote at the meeting.

Q: How does the PDC Board recommend that I vote?

The PDC Board unanimously recommends that PDC stockholders vote “FOR” the merger proposal, “FOR” the merger-related compensation proposal and “FOR” the adjournment proposal.

Q: What do I need to do now?

After carefully reading and considering the information contained in and incorporated by reference into, this proxy statement/prospectus, please vote your shares as soon as possible so that your shares will be represented at the special meeting. Please follow the instructions set forth on the accompanying proxy card or on the voting instruction form provided by the record holder if your shares are held in the name of your broker, bank or other nominee.

Please do not submit your PDC stock certificates at this time. If the merger is completed, you will receive instructions for surrendering your PDC stock certificates in exchange for shares of Chevron common stock from the exchange agent.

Please carefully consider the information contained in, and incorporated by reference into, this proxy statement/prospectus. Whether or not you plan to attend the special meeting, PDC encourages you to submit your proxy to vote via the internet, by telephone or by mail so that your shares will be voted in accordance with your wishes even if you later decide not to attend the special meeting.

Q: What is the difference between holding shares as a stockholder of record and as a beneficial owner?

If your shares of PDC common stock are registered directly in your name with the transfer agent of PDC, Broadridge Corporate Issuer Solutions, Inc., you are considered the stockholder of record with respect to those shares. As the stockholder of record, you have the right to vote or to grant a proxy for your vote directly to PDC or to a third party to vote at the special meeting.

If your shares are held by a broker, bank or other nominee, you are considered the beneficial owner of shares held in “street name”, and your broker, bank or other nominee is considered the stockholder of record with

5

respect to those shares. Your broker, bank or other nominee will send you, as the beneficial owner, voting instruction forms for you to use in directing the broker, bank or other nominee in how to vote your shares. You should follow the instructions provided by them to vote your shares. You are invited to attend the special meeting and you may cast your vote virtually at the special meeting by following the instructions at www.virtualshareholdermeeting.com/PDCE2023SM.

Q: If my shares are held in “street name” by a broker, bank or other nominee, will my broker, bank or other nominee vote my shares for me?

If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in street name by returning a proxy card or voting instruction form directly to PDC. Your broker, bank or other nominee is obligated to provide you with a voting instruction form for you to use. You may also cast your vote virtually at the special meeting by following the instructions at www.virtualshareholdermeeting.com/PDCE2023SM.

Applicable stock exchange rules permit brokers to vote their customers’ stock held in street name on routine matters when the brokers have not received voting instructions from their customers. Those rules do not, however, allow brokers to vote their customers’ stock held in street name on non-routine matters unless they have received voting instructions from their customers. In such cases, the uninstructed shares for which the broker is unable to vote are called broker non-votes. The merger proposal, the merger-related compensation proposal and the adjournment proposal are non-routine matters on which brokers are not allowed to vote unless they have received voting instructions from their customers.

If you are a PDC “street name” stockholder and you do not instruct your broker, bank or other nominee on how to vote your shares:

Q: What if I fail to vote or abstain?

For purposes of the special meeting, an abstention occurs when a stockholder attends the special meeting virtually and does not vote or returns a proxy with an “abstain” instruction.

Merger proposal: An abstention or failure to vote will have the same effect as a vote cast “AGAINST” the merger proposal.

Merger-related compensation proposal: An abstention will have the same effect as a vote cast “AGAINST” the merger-related compensation proposal. If a PDC stockholder is not present virtually at the special meeting and does not respond by proxy, it will have no effect on the vote for the merger-related compensation proposal (assuming a quorum is present).

Adjournment proposal: An abstention will have the same effect as a vote cast “AGAINST” the adjournment proposal. If a PDC stockholder is not present virtually at the special meeting and does not respond by proxy, it will have no effect on the vote for the adjournment proposal (assuming a quorum is present).

Q: What will happen if I return my proxy card or voting instruction form without indicating how to vote?

If you sign and return your proxy card or voting instruction form without indicating how to vote on any particular proposal, the PDC common stock represented by your proxy will be voted as recommended by the PDC Board with respect to that proposal.

Q: May I change or revoke my vote after I have delivered my proxy card or voting instruction form?

Yes. If you are a record holder, you may change or revoke your vote before your proxy is voted at the special meeting as described herein. You may do this in one of four ways:

If you are a street name stockholder and you vote by proxy, you may later revoke your proxy by informing the holder of record in accordance with that entity’s procedures.

Q: What are the material U.S. federal income tax consequences of the merger?

The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and Chevron and PDC intend to report the merger consistent with such qualification. Assuming the merger so qualifies, a U.S. holder (as defined in “The Merger—Material U.S. Federal Income Tax Consequences”) of PDC common stock generally would not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of PDC common stock for Chevron common stock (except for any gain or loss, if any, recognized with respect to any cash received in lieu of a fractional share of Chevron common stock). However, it is not a condition to Chevron’s obligation or PDC’s obligation to complete the transactions that the merger be treated as a “reorganization” or that Chevron or PDC receive an opinion from counsel to that effect. Chevron and PDC have not sought, and will not seek, any ruling from the Internal Revenue Service (the “IRS”) regarding any matters related to the transactions, and as a result, there can be no assurance that the IRS would not assert that the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, or that a court would not sustain such a position.

If any requirement for qualification as a “reorganization” within the meaning of Section 368(a) of the Code is not met, then a U.S. holder of PDC common stock generally would recognize gain or loss in an amount equal to the difference, if any, between the fair market value of the Chevron common stock received in the merger, and such U.S. holder’s aggregate tax basis in the corresponding PDC common stock surrendered in the merger.

All holders of PDC common stock should consult with a tax advisor to determine the particular U.S. federal, state or local or non-U.S. income or other tax consequences of the merger to them. See “The Merger—Material U.S. Federal Income Tax Consequences” beginning on page [    ] for additional information.

Q: Am I entitled to exercise appraisal rights in connection with the merger instead of receiving the merger consideration for my shares of PDC common stock?

PDC stockholders are not entitled to appraisal rights in connection with the merger. For additional information, see “The Merger—No Appraisal Rights” beginning on page [    ].

7

Q: What will happen to PDC stock-based awards?

At the effective time of the merger:

8

Q: What happens if I sell my shares of PDC common stock after the record date but before the special meeting?

The record date for the special meeting (the close of business on [                ], 2023) is earlier than the date of the special meeting and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of PDC common stock after the record date but before the date of the special meeting, you will retain your right to vote at the special meeting. However, you will not have the right to receive the merger consideration to be received by PDC stockholders in the merger. In order to receive the merger consideration, you must hold your shares through completion of the merger.

Q: Are there any risks that I should consider in deciding whether to vote in favor of the merger proposal?

Yes. You should read and carefully consider the risk factors set forth in the section entitled “Risk Factors” beginning on page [    ]. You also should read and carefully consider the risk factors of Chevron and PDC contained in the documents that are incorporated by reference into this proxy statement/prospectus.

Q: What should I do if I receive more than one set of voting materials?

If you hold shares of PDC common stock in “street name” and also directly as a record holder or otherwise or if you hold shares of PDC common stock in more than one brokerage account, you may receive more than one set of voting materials relating to the special meeting. Please complete, sign, date and return each proxy card (or cast your vote by telephone or internet as provided on your proxy card) or otherwise follow the voting instructions provided in this proxy statement/prospectus in order to ensure that all of your shares of PDC common stock are voted. If you hold your shares in “street name” through a broker, bank or other nominee, you should follow the procedures provided by your broker, bank or other nominee to vote your shares.

Q: Who will tabulate and certify the vote?

Representatives of Broadridge Financial Solutions will tabulate the votes cast at the special meeting, and representatives of American Election Services LLC will act as the Independent Inspector of Election.

Q: Where can I find the voting results of the special meeting?

The preliminary voting results will be announced at the special meeting. In addition, within four business days following certification of the final voting results, PDC intends to file the final voting results with the SEC on a Current Report on Form 8-K.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This document contains certain forward-looking statements with respect to the merger between Chevron and PDC, including any statements regarding the expected timetable for completing the merger, the ability to complete the merger, the expected benefits of the merger (including anticipated accretion to return on capital employed, free cash flow, and earnings per share, as well as the potential to deliver higher returns and lower Chevron’s carbon intensity) and projected operational and capital synergies, projected financial information, future opportunities, and any other statements regarding Chevron’s and PDC’s future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events or performance. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “expects,” “intends,” “plans,” “targets,” “advances,” “commits,” “drives,” “aims,” “forecasts,” “projects,” “believes,” “approaches,” “seeks,” “schedules,” “estimates,” “positions,” “pursues,” “progress,” “may,” “can,” “could,” “should,” “will,” “budgets,” “outlook,” “trends,” “guidance,” “focus,” “on track,” “goals,” “objectives,” “strategies,” “opportunities,” “poised,” “potential,” “ambitions,” “aspires” and similar expressions. All such forward-looking statements are based on current expectations of Chevron’s and PDC’s management and therefore involve estimates and assumptions that are subject to risks, uncertainties and other factors that could cause actual results to differ materially from the results expressed in the statements. Key factors that could cause actual results to differ materially from those projected in the forward-looking statements include, but are not limited to:

22

23

These forward-looking statements reflect Chevron’s and PDC’s current views with respect to future events and are based on numerous assumptions and assessments made by Chevron and PDC in light of their experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors they believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this document could cause Chevron’s and PDC’s plans with respect to the merger, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this document are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this proxy statement/prospectus or, in the case of a document incorporated by reference, as of the date of that document. Neither Chevron nor PDC assumes any obligation to update the information contained in this document (whether as a result of new information, future events or otherwise), except as required by applicable law.

24

RISK FACTORS

In addition to the other information included in and incorporated by reference into this proxy statement/prospectus, including, among others, the matters addressed in “Cautionary Note Regarding Forward-Looking Statements” beginning on page [    ], PDC stockholders should carefully consider the following risk factors before deciding whether to vote for the proposal to adopt the merger agreement. In addition, you should read and consider the risks associated with each of the businesses of PDC and Chevron because these risks will relate to Chevron following the completion of the merger. Descriptions of some of these risks can be found in the respective Annual Reports of Chevron and PDC on Form 10-K for the fiscal year ended December 31, 2022, as such risks may be updated or supplemented in each company’s subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, which are incorporated by reference into this proxy statement/prospectus. You should also consider the other information in this document and the other documents incorporated by reference into this document. See “Where You Can Find More Information” beginning on page [    ].

Risks Related to the Merger

The merger is subject to conditions, some or all of which may not be satisfied, or completed on a timely basis, if at all. Failure to complete the merger in a timely manner or at all could have adverse effects on PDC.

The completion of the merger is subject to a number of conditions, including, among others, (i) the approval by PDC stockholders of the adoption of the merger agreement and (ii) U.S. regulatory approvals, which make the completion and timing of the completion of the merger uncertain. For a more detailed discussion regarding conditions to the merger, see “The Merger Agreement—Conditions to Completion of the Merger”, beginning on page [    ]. Also, either Chevron or PDC may terminate the merger agreement if the merger has not been consummated by May 22, 2024 (or November 26, 2024, if the end date is extended pursuant to the merger agreement), except that this right to terminate the merger agreement will not be available to any party whose failure to perform any obligation under the merger agreement has principally caused or resulted in the failure of the merger to be consummated on or before that date.

If the merger is not completed, PDC’s ongoing business, financial condition, financial results and stock price may be materially adversely affected. Without realizing any of the benefits of having completed the merger, Chevron and PDC will be subject to a number of risks, including the following:

25

In addition, if the merger is not completed, Chevron and/or PDC could be subject to litigation related to any failure to complete the merger or related to any enforcement proceeding commenced against Chevron or PDC to perform their respective obligations under the merger agreement. The materialization of any of these risks could adversely impact Chevron’s and PDC’s respective ongoing businesses, financial condition, financial results and stock price. Similarly, delays in the completion of the merger could, among other things, result in additional transaction costs, loss of revenue or other negative effects associated with uncertainty about completion of the merger.

If the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the PDC stockholders may be required to pay substantial U.S. federal income taxes.

The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and Chevron and PDC intend to report the merger consistent with such qualification. However, it is not a condition to PDC’s obligation or Chevron’s obligation to complete the transactions that the merger be treated as a “reorganization” or that Chevron or PDC receive an opinion from counsel to that effect. Chevron and PDC have not sought, and will not seek, any ruling from the IRS regarding any matters relating to the transactions, and as a result, there can be no assurance that the IRS would not assert, or that a court would not sustain, a position contrary to the treatment of the merger as a “reorganization” within the meaning of Section 368(a) of the Code. If the IRS or a court determines that the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, a holder of PDC common stock would generally recognize taxable gain or loss upon the exchange of PDC common stock for Chevron common stock pursuant to the merger. See “The Merger—Material U.S. Federal Income Tax Consequences” beginning on page [     ].

The merger agreement contains provisions that limit PDC’s ability to pursue alternatives to the merger, could discourage a potential competing acquiror of PDC from making a favorable alternative transaction proposal and, in specified circumstances, could require PDC to pay a termination fee to Chevron.

The merger agreement contains certain provisions that restrict PDC’s ability to initiate, solicit, knowingly encourage or facilitate or, subject to certain exceptions, engage in discussions or negotiations with respect to, or approve or recommend, any third-party proposal for an alternative transaction. Further, even if the PDC Board withdraws or qualifies its recommendation with respect to the adoption of the merger agreement, unless the merger agreement has been terminated in accordance with its terms, PDC will still be required to submit each of its merger-related proposals to a vote at the special meeting. In addition, Chevron generally has an opportunity to offer to modify the terms of the transactions contemplated by the merger agreement in response to any third-party alternative transaction proposal before the PDC Board may withdraw or qualify its recommendation with respect to the merger-related proposal or otherwise terminate the merger agreement.

In some circumstances, upon termination of the merger agreement, PDC will be required to pay a termination fee of $225,000,000 to Chevron. See the sections titled “Summary—No Solicitation” and “The Merger Agreement—Termination of the Merger Agreement” beginning on pages [    ] and [    ], respectively.

These provisions could discourage a potential third-party acquiror or merger partner that might have an interest in acquiring all or a significant portion of PDC or pursuing an alternative transaction from considering or proposing such a transaction, even if it were prepared to pay consideration with a higher per share cash or market value than the per share cash or market value proposed to be received or realized in the merger. In particular, the termination fee, if applicable, could result in a potential third-party acquiror or merger partner proposing to pay a lower price to the PDC stockholders than it might otherwise have proposed to pay absent such a fee.

If the merger agreement is terminated and PDC determines to seek another business combination, PDC may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the merger.

26

The merger is subject to the requirements of the HSR Act, and regulatory authorities may impose conditions that could have an adverse effect on PDC and/or Chevron following the transaction or that could delay, prevent or increase the costs associated with completion of the merger.

Before the merger may be completed, any waiting period (or extension thereof) under the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which is referred to as the “HSR Act”, must have expired or been terminated. In deciding whether to grant the required approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations or other confirmations, the relevant governmental entities may impose requirements, limitations or costs or place restrictions on the conduct of the business of Chevron following the transaction. Under the merger agreement, Chevron and PDC have agreed to use their respective reasonable best efforts to obtain as soon as practicable all approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations required to be obtained from any third party or governmental body, agency, authority or official which are necessary, proper or advisable to consummate the merger. However, notwithstanding the foregoing, Chevron and its subsidiaries are not required to take (or to request or authorize PDC or any of its subsidiaries to undertake) any action if it would, or would reasonably be expected to, result in a substantial detriment. For this purpose, “substantial detriment” means any requirement to:

Chevron will, however, if required by an applicable governmental agency, body, authority or entity, agree to any requirement to provide prior notice to, or to obtain prior approval from, any governmental agency, body, authority or entity to the extent such requirement is immaterial to Chevron.

In addition, governmental agencies, bodies, authorities or entities may impose conditions, terms, obligations or restrictions in connection with their approval of or consent to the merger, and such conditions, terms, obligations or restrictions may delay completion of the merger or impose additional material costs on or materially limit Chevron’s revenues following the completion of the merger. There can be no assurance that governmental agencies, bodies, authorities or entities will choose not to impose such conditions, terms, obligations or restrictions, and, if imposed, such conditions, terms, obligations or restrictions may delay or lead to the abandonment of the merger. At any time before or after consummation of the merger, notwithstanding the early termination of the applicable waiting period under the HSR Act, the FTC, the DOJ or any state could take such action under antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or seeking the divestiture of substantial assets of Chevron or PDC or their respective subsidiaries. For a more detailed description of the regulatory review process, see the section entitled “The Merger—Regulatory Approvals Required for the Merger” beginning on page [     ].

27

The exchange ratio is fixed and will not be adjusted in the event of any change in either Chevron’s or PDC’s stock price.

Upon completion of the merger, each share of PDC common stock will be converted into the right to receive 0.4638 of a validly issued, fully paid and non-assessable share of Chevron common stock. This exchange ratio was fixed in the merger agreement and will not be adjusted for changes in the market price of either Chevron common stock or PDC common stock between the date the merger agreement was signed and completion of the merger. Due to the fixed exchange ratio, fluctuations in the price of Chevron common stock will drive corresponding changes in the value of the merger consideration payable to each PDC stockholder. As a result, changes in the price of Chevron common stock prior to the completion of the merger will affect the market value that PDC stockholders will become entitled to receive on the date of the closing. Stock price changes may result from a variety of factors (many of which are beyond Chevron’s or PDC’s control), such as changes in Chevron’s or PDC’s respective business, operations and prospects; changing crude oil and natural gas prices, as well as crude oil production quotas; overall demand for crude oil and natural gas commodities; the continued effects of the COVID-19 pandemic and governmental and business responses to the pandemic; and changes in government rules and regulations in the countries in which each of Chevron and PDC operate.

The price of Chevron common stock has fluctuated during the period between the date the merger agreement was executed and the date of this proxy statement/prospectus, and may continue to change through the date of the special meeting and the date the merger is completed. For example, based on the range of closing prices of Chevron common stock during the period from May 19, 2023, the last full trading day before the public announcement of the merger, through [                ], 2023, the latest practicable trading date before the date of this proxy statement/prospectus, the exchange ratio represented the market value of the merger consideration ranging from a high of $[                ] to a low of $[                ] for each share of PDC common stock. The actual market value of the Chevron common stock received by holders of PDC common stock upon completion of the merger may be outside this range.

These variations could result from changes in the business, operations or prospects of Chevron or PDC prior to or following the completion of the merger, regulatory considerations, general market and economic conditions and other factors both within and beyond the control of Chevron or PDC. At the time of the special meeting, PDC stockholders will not know with certainty the value of the shares of Chevron common stock that they will receive upon completion of the merger.

Members of the PDC Board and management have interests in the merger that are different from, or in addition to, those of other stockholders.

In considering whether to adopt the merger agreement and approve the transactions contemplated thereby, PDC stockholders should recognize that members of management and the PDC Board have interests in the merger that differ from, or are in addition to, their interests as stockholders of PDC.

The executive officers of PDC have arrangements with PDC that provide for certain severance payments or benefits, accelerated vesting of certain equity-based awards and other rights and other payments or benefits upon completion of the merger and/or if their employment or service is terminated under certain circumstances following the completion of the merger. The directors of PDC have arrangements with PDC that provide for accelerated vesting of certain equity-based awards following the completion of the merger. In addition, the executive officers and directors of PDC also have rights to indemnification, advancement of expenses and directors’ and officers’ liability insurance that will survive the completion of the merger. The PDC Board was aware of these interests and considered them, among other matters, in approving the merger agreement and making its recommendation that the PDC stockholders vote “FOR” the merger proposal and “FOR” the merger-related compensation proposal.

These interests are further described in “The Merger—Interests of Directors and Executive Officers of PDC in the Merger” beginning on page [    ].

28

Each party is subject to business uncertainties and contractual restrictions while the proposed merger is pending, which could adversely affect each party’s business and operations.

In connection with the pendency of the merger, it is possible that some customers, suppliers and other persons with whom Chevron or PDC has a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with Chevron or PDC, as the case may be, as a result of the merger. Under the terms of the merger agreement, each of Chevron and PDC is subject to certain restrictions on the conduct of its respective business prior to completing the merger, which may adversely affect Chevron’s ability to acquire assets or PDC’s ability to execute certain of its business strategies, including, with respect to PDC, the ability in certain cases to enter into or amend contracts, acquire or dispose of assets, incur indebtedness or incur capital expenditures. Such limitations could adversely affect each party’s businesses and operations prior to the completion of the merger. See “The Merger Agreement—Covenants and Agreements—Conduct of Business” beginning on page [    ].

Each of the risks described above may be exacerbated by delays or other adverse developments with respect to the completion of the merger.

The opinion of PDC’s financial advisor will not reflect changes in circumstances between the signing of the merger agreement and the completion of the merger.

PDC has received an opinion from its financial advisor in connection with the signing of the merger agreement, but has not obtained any updated opinion from its financial advisor as of the date of this proxy statement/prospectus. Changes in the operations and prospects of Chevron or PDC, general market and economic conditions and other factors that may be beyond the control of Chevron or PDC, and on which PDC’s financial advisor’s opinion was based, may significantly alter the value of Chevron or PDC or the prices of the shares of Chevron common stock or PDC common stock by the time the merger is completed. The opinion does not speak as of the time the merger will be completed or as of any date other than the date of such opinion. Because PDC does not currently anticipate asking its financial advisor to update its opinion, the opinion will not address the fairness of the merger consideration from a financial point of view at the time the merger is completed. The PDC Board’s recommendation that PDC stockholders vote “FOR” approval of the merger proposal, “FOR” the non-binding merger-related compensation proposal and “FOR” the adjournment proposal, however, is made as of the date of this proxy statement/prospectus.

For a description of the opinion that PDC received from its financial advisor, see the section entitled “The Merger—Opinion of PDC’s Financial Advisor” beginning on page [    ]. A copy of the opinion of J.P. Morgan, PDC’s financial advisor, is attached as Annex B to this proxy statement/prospectus.

PDC may be unable to retain key employees during the pendency of the merger.

In connection with the pending merger, PDC’s current and prospective employees may experience uncertainty about their future roles with Chevron following the merger, which may materially adversely affect its ability to attract and retain key personnel during the pendency of the merger. Key employees may depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Chevron following the merger. Accordingly, no assurance can be given that PDC will be able to retain key employees to the same extent that PDC has been able to in the past.

Potential litigation against Chevron and PDC could result in substantial costs, an injunction preventing the completion of the merger and/or a judgment resulting in the payment of damages.

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into merger agreements. Even if such a lawsuit is unsuccessful, defending against these claims can result

29

in substantial costs. An adverse judgment could result in monetary damages, which could have a negative impact on Chevron’s and PDC’s respective liquidity and financial condition.

Stockholders of PDC may file lawsuits against Chevron, PDC and/or the directors and officers of either company in connection with the merger. These lawsuits could prevent or delay the completion of the merger and result in significant costs to PDC and/or Chevron, including any costs associated with the indemnification of directors and officers. There can be no assurance that any of the defendants will be successful in the outcome of any potential lawsuits.

Completion of the merger may trigger change in control or other provisions in certain agreements to which PDC is a party, which may have an adverse impact on Chevron’s business and results of operations after the merger.

The completion of the merger may trigger change in control and other provisions in certain agreements to which PDC is a party. If Chevron and PDC are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements or seeking monetary damages. Even if Chevron and PDC are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to PDC or Chevron following the transaction.

PDC stockholders are not entitled to appraisal rights in connection with the merger.

Appraisal rights are statutory rights that enable stockholders to dissent from certain extraordinary transactions, such as certain mergers, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the applicable transaction. Under the DGCL, holders of shares of PDC common stock will not have rights to an appraisal of the fair value of their shares in connection with the merger. See “The Merger—No Appraisal Rights” beginning on page [    ] for additional information.

The shares of Chevron common stock to be received by PDC stockholders upon completion of the merger will have different rights from shares of PDC common stock.

Upon completion of the merger, PDC stockholders will no longer be stockholders of PDC but will instead become stockholders of Chevron, and their rights as Chevron stockholders will be governed by the terms of Chevron’s certificate of incorporation, as amended (“Chevron’s certificate of incorporation”), and Chevron’s by-laws, as amended (“Chevron’s By-Laws”). The terms of Chevron’s certificate of incorporation and Chevron’s By-Laws are in some respects materially different than the terms of PDC’s certificate of incorporation, as amended (“PDC’s certificate of incorporation”), and PDC’s Bylaws, which currently govern the rights of PDC stockholders. See “Comparison of Rights of Stockholders of Chevron and PDC” beginning on page [    ] for a discussion of the different rights associated with shares of PDC common stock and shares of Chevron common stock.

PDC stockholders will have a significantly reduced ownership and voting interest after the merger and will exercise less influence over the policies of Chevron following the transaction than they now have on the policies of PDC.

Chevron stockholders currently have the right to vote in the election of the Chevron Board and on other matters affecting Chevron. PDC stockholders currently have the right to vote in the election of the PDC Board and on other matters affecting PDC. Immediately after the merger is completed, it is expected that current Chevron stockholders will own approximately [    ]% of the shares of outstanding common stock of Chevron following the transaction, and current PDC stockholders will own approximately [    ]% of the common stock outstanding of Chevron following the transaction. As a result, current PDC stockholders will have significantly less influence on the policies of Chevron than they now have on the policies of PDC.

30

Risks Relating to Chevron After Completion of the Merger

Chevron may not achieve the intended benefits and the merger may disrupt its current plans or operations.

There can be no assurance that Chevron will be able to successfully integrate PDC’s assets or otherwise realize the expected benefits of the potential transaction (including capital expenditures efficiencies and operational synergies). Difficulties in integrating PDC into Chevron may result in Chevron performing differently than expected, in operational challenges or in the failure to realize anticipated synergies and efficiencies in the expected timeframe or at all, in which case the merger may not be accretive to Chevron’s return on average capital employed (calculated as net income (loss) attributable to Chevron (adjusted for after-tax interest expense and noncontrolling interest) divided by average capital employed, which is computed by averaging the sum of capital employed at the beginning and end of the year), free cash flow (calculated as cash provided by operating activities less capital expenditures) and earnings per share within one year after the completion of the merger. The integration of the two companies may result in material challenges, including the diversion of management’s attention from ongoing business concerns; retaining key management and other employees; retaining or attracting business and operational relationships; the possibility of faulty assumptions underlying expectations regarding the integration process and associated expenses; consolidating corporate and administrative infrastructures and eliminating duplicative operations; coordinating geographically separate organizations; unanticipated issues in integrating information technology, communications and other systems; as well as potential unknown liabilities, unforeseen expenses relating to integration, or delays associated with the acquisition.

The market price of Chevron’s common stock after the merger may be affected by factors different from those affecting the price of Chevron or PDC common stock before the merger.

Upon completion of the merger, holders of Chevron common stock and PDC common stock will be holders of Chevron common stock. As the businesses of Chevron and PDC are different, the results of operations as well as the price of Chevron’s common stock may in the future be affected by factors different from those factors affecting Chevron and PDC as independent stand-alone companies. Chevron following the transaction will face additional risks and uncertainties that Chevron or PDC may currently not be exposed to as independent companies.

The market price of Chevron’s common stock may decline as a result of the merger.

The market price of Chevron common stock may decline as a result of the merger if, among other things, it is unable to achieve the expected benefits and synergies of the potential transaction, if the merger is not completed within the anticipated timeframe or if the transaction costs related to the merger are greater than expected. The market price also may decline if Chevron does not achieve the perceived benefits and expected synergies of the transaction as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the merger on Chevron’s financial position, results of operations or cash flows is not consistent with the expectations of financial or industry analysts.

The merger may result in a loss of customers, distributors, suppliers, vendors, landlords and other business partners and may result in the termination of existing contracts.

Following the merger, some of the customers, distributors, suppliers, vendors, landlords and other business partners of PDC may terminate or scale back their current or prospective business relationships with Chevron. Some customers may not wish to source a larger percentage of their needs from a single company or may feel that Chevron is too closely allied with one of their competitors. In addition, PDC has contracts with customers, distributors, suppliers, vendors, landlords and other business partners that may require it to obtain consents from these other parties in connection with the merger, which may not be obtained on favorable terms or at all. If relationships with customers, distributors, suppliers, vendors, landlords and other business partners are adversely affected by the merger, or if Chevron, following the merger, loses the benefits of the contracts of PDC, Chevron’s business and financial performance could suffer.

31

Following the completion of the merger, Chevron may incorporate PDC’s hedging activities into Chevron’s business, and Chevron may be exposed to additional commodity price risks arising from such hedges.

To mitigate its exposure to changes in commodity prices, PDC hedges oil, natural gas and natural gas liquid (“NGL”) prices from time to time, primarily through the use of certain derivative instruments. If Chevron assumes existing PDC hedges, then Chevron will bear the economic impact of all of PDC’s current hedges following the completion of the merger. Actual crude oil, natural gas and NGL prices may differ from Chevron’s expectations and, as a result, such hedges may or may not have a negative impact on Chevron’s business.

Chevron’s By-Laws will govern Chevron following the merger and provide that a state or federal court located within the State of Delaware will be the exclusive forum for substantially all disputes between Chevron (after the merger) and its stockholders, which could limit its stockholders’ ability to obtain a favorable judicial forum for disputes with Chevron or its directors, officers or other employees.

Chevron’s By-laws provide that, unless Chevron consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Chevron, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of Chevron to Chevron or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or (iv) any action asserting a claim governed by the internal affairs doctrine shall be a state or federal court located within the state of Delaware, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. Chevron reserves the right to assert that this exclusive forum provision applies to any derivative action or proceeding brought by a stockholder to procure a judgment in Chevron’s favor, including derivative actions purporting to assert on Chevron’s behalf any claims it possesses against third parties that arise under the federal securities laws (e.g., the Securities Act and the Exchange Act). It is, however, uncertain whether a court would enforce this exclusive forum provision with respect to a derivative action or proceeding brought by a stockholder to enforce Chevron’s rights under the Securities Act or Exchange Act. In addition, stockholders cannot waive, and this exclusive forum provision does not purport to waive, Chevron’s own compliance with the federal securities laws and the rules and regulations thereunder.

This exclusive forum provision may limit the ability of a stockholder, including a former PDC stockholder who becomes a Chevron stockholder after the merger is completed, to bring a claim in a judicial forum of its choosing for disputes with Chevron or its directors, officers or other employees, which may discourage lawsuits against Chevron and its directors, officers and other employees. In addition, stockholders who do bring a claim in a state or federal court located within the State of Delaware could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. In addition, the court located in the State of Delaware may reach different judgments or results than would other courts, including courts where a stockholder would otherwise choose to bring the action, and such judgments or results may be more favorable to Chevron than to its stockholders.

THE MERGER

The following is a discussion of the transaction and the material terms of the merger agreement between Chevron and PDC. You are urged to read the merger agreement carefully and in its entirety. A copy of the merger agreement is attached as Annex A to this proxy statement/prospectus and incorporated by reference herein. This summary does not purport to be complete and may not contain all of the information about the merger that is important to you. This section is not intended to provide you with any factual information about Chevron or PDC. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings Chevron and PDC make with the SEC that are incorporated by reference into this document, as described in “Where You Can Find More Information” beginning on page [    ].

Background of the Merger

The PDC Board and company management regularly review and assess PDC’s performance, strategy, financial position, leverage, opportunities and risks in light of current business and economic conditions, developments in the oil and gas exploration and production sector, and potential future industry developments. These reviews have taken place consistently through different macro environments. One such strategic review session occurred in September 2022 during which the management of PDC presented to the PDC Board on various strategic growth opportunities, which included an evaluation of potential strategic merger combinations, acquisition opportunities, and joint ventures. These opportunities included assets within and outside PDC’s current asset portfolio. PJT Partners LP (“PJT Partners”) also participated in the discussions with the PDC Board. Following this review, the PDC Board directed management to continue its strategy of pursuing growth through accretive acquisitions, focusing primarily, though not exclusively, on potential opportunities in the Permian Basin, due to, among other things, the relatively large number of potential target companies operating in the basin, its favorable geological and operating characteristics and a desire to build scale in the Permian Basin to complement PDC’s Colorado operations.

PDC’s pursuit of its growth strategy, both before and after the September 2022 review, has been shaped by factors including (i) increased regulatory scrutiny and uncertainty in Colorado, (ii) commodity price volatility and evolving investor sentiment regarding the upstream energy industry and (iii) a challenging market for acquisitions. Each of these factors is discussed briefly below.

In 2018, opponents of oil and gas development in Colorado supported Proposition 112, a ballot initiative to increase the distance between all new oil and gas development not on federal land and any occupied structure or broadly defined “vulnerable area”. If enacted, Proposition 112 would have effectively prohibited the vast majority of PDC’s future drilling activities in Colorado. Although Proposition 112 was defeated in the November 2018 election, a new law, referred to as Senate Bill 19-181, was enacted in April 2019. Senate Bill 19-181 made a number of changes to oil and gas regulation in Colorado, in particular through “local control” provisions that give county and municipal governmental authorities the ability to regulate facility siting and surface impacts of oil and natural gas development and to impose requirements that are stricter than state requirements. Since the enactment of Senate Bill 19-181, a permitting process under the law has been developed by the Colorado Oil and Gas Conservation Commission, and PDC has had several “Oil and Gas Development Plans” and one “Comprehensive Area Plan” approved under the new rules. However, regulatory uncertainties remain. For example, new ballot initiatives have been proposed for the November 2024 election that, if passed, may generally restrict oil and gas permitting in Colorado by the end of 2030.

With respect to commodity prices, the historical volatility of those prices has continued in recent years, with dramatic collapses in the price of oil in 2014 and 2020 resulting in severe declines in the trading price of many energy company securities. In response to these events, investors have increasingly emphasized the critical importance of balance sheet strength, financial returns from drilling activities, generation of free cash flow, the careful management of G&A and other costs and return of capital. PDC, like other companies in the upstream oil and gas industry, has responded to changing investor priorities in part by seeking acquisitions that provide

33

operational efficiencies and corporate synergies. Under the direction of the PDC Board, the company’s management has explored numerous potential acquisitions and other strategic alternatives, within and outside of the basins in which PDC currently operates, that would increase the scale and efficiency of its operations and its inventory of drilling locations. As a result of these efforts, PDC has successfully completed acquisitions, including a merger with SRC Energy Inc. in 2020 and an acquisition of Great Western Petroleum, LLC in 2022.

However, PDC has found continued growth through acquisitions to be challenging due to several factors including (i) the reluctance of some non-Colorado parties to merge with, or receive stock as consideration from, a Colorado operator and thereby assume exposure to Colorado regulatory risk, (ii) the limited additional top-tier properties in Colorado that would potentially be available for acquisition, (iii) the competitiveness of the market for properties and companies operating in the Permian Basin, resulting in high acquisition prices impacting potential accretion, and (iv) with respect to properties outside of the DJ or Permian Basins, the potential difficulty involved in achieving significant operational efficiencies and corporate synergies. For example, in 2022, PDC had discussions regarding the following potential transactions:

34

In May 2021, Bart Brookman, Lance Lauck and Scott Meyers, PDC’s CEO, Executive Vice President Corporate Development & Strategy and CFO, respectively, met with Frank Mount, Chevron’s Vice President – M&A and Origination, to discuss the possibility of PDC purchasing some or all of its Denver-Julesburg Basin (“DJ Basin”) assets and/or certain Permian Basin assets from Chevron. Mr. Mount indicated at that meeting that Chevron was not interested in such a transaction at that time. In July 2021, Mr. Lauck, and other representatives of PDC, met with Norman Hansen, Chevron’s Director, Origination Americas, and other representatives of Chevron, to discuss the possibility of a Permian Basin joint venture whereby PDC would establish terms to drill future wells on certain Chevron properties. After internal reviews, Mr. Hansen indicated that Chevron was not interested in such a transaction at that time.

Messrs. Brookman and Lauck met again with Mr. Mount in May 2022 to discuss a potential purchase by PDC of certain Chevron acreage, and Mr. Mount again said that Chevron was not interested in such a transaction. In December 2022, Mr. Mount and Mr. Brookman met to discuss possible business combinations and the low market premiums many recent transactions had received given existing market conditions. Shortly after this meeting, Mr. Brookman conveyed the substance of the conversation to Mark Ellis, the Chairman of the PDC Board, following which Mr. Brookman discussed the possibility of a transaction with Chevron with several other PDC directors. Mr. Brookman informed Mr. Ellis that he would raise the subject at the meeting of the PDC Board scheduled for February 2023. Mr. Mount indicated Chevron’s interest in potentially acquiring PDC to Mr. Brookman at an industry conference in January 2023.

On January 20, 2023, Mr. Mount and Mr. Brookman spoke, and as part of that discussion, Mr. Mount indicated that the Chevron Board would be made aware of the possible effort to acquire PDC. A follow-up call on February 8, 2023 confirmed Chevron’s interest. On February 17, 2023, Mr. Mount and Mr. Brookman discussed various procedural aspects of a potential transaction, including the anticipated advisors for each company and the due diligence process. Mr. Mount indicated that Chevron was working in good faith on its internal analysis of a potential acquisition and moving through the Chevron internal approval process with respect to potentially providing a written offer.

The PDC Board met on February 20, 2023 to discuss Chevron’s suggestion that Chevron might propose a transaction. After discussion of various possible courses of action, and noting PDC’s recent unsuccessful efforts to pursue significant mergers or acquisitions, the PDC Board indicated to management that it should continue to discuss with Chevron the possibility of a transaction. The PDC Board also indicated support for management’s proposal to engage J.P. Morgan as PDC’s financial advisor in connection with a potential transaction and Wachtell, Lipton, Rosen & Katz (“Wachtell”) and Davis Graham & Stubbs LLP (“DGS”) as its legal advisors.

On February 22, 2023, PDC entered into an engagement letter with J.P. Morgan. J.P. Morgan was selected based on its industry experience, as well as its long-standing relationship with, and knowledge of, PDC. Mr. Mount and Mr. Brookman spoke the same day to discuss certain high level due diligence issues and the process for a potential transaction. Mr. Brookman indicated on this call his belief that the PDC Board might be most receptive to an all-stock offer so that PDC shareholders would benefit from participating in the value and opportunities of Chevron, including its worldwide asset portfolio, dividends, share repurchases and future growth. On February 23, 2023, PDC and Chevron entered into a mutual confidentiality agreement, which included a customary standstill restriction with a customary “fall-away” provision that renders the standstill inapplicable following PDC’s entry into a definitive agreement relating to an acquisition of a majority of PDC’s voting securities or assets, or any third party commencing a tender offer for a majority of PDC’s outstanding voting securities and PDC or the PDC Board accepting such offer. On February 24, 2023 and March 3, 2023, Mr. Mount and Mr. Brookman spoke again to discuss a potential presentation by members of PDC management to members of Chevron management on March 16 or 17. Mr. Mount indicated that Chevron was not prepared to make an offer in advance of the management presentation.

On February 27, 2023, the PDC Board met, and members of PDC management provided an update regarding the potential transaction process, including due diligence, the terms of the confidentiality agreement

35

and J.P. Morgan’s engagement. The PDC Board discussed various aspects of the potential transaction at this meeting, including a comparison of the potential benefits and potential limitations of receiving stock versus cash consideration and alternatives. On March 6, 2023, the PDC Board met again to review and discuss with J.P. Morgan certain financial aspects of a potential transaction and certain financial information regarding Chevron and PDC, including certain preliminary financial analyses regarding PDC.

On March 10, 2023, Mr. Mount and Mr. Brookman had a call to discuss, among other things, the due diligence process and potential exchange ratios for the transaction. Mr. Brookman indicated that the PDC Board would be looking for a “strong” offer that reflected PDC’s intrinsic value and a premium over the current trading price of PDC’s common stock.

On March 13, 2023, the PDC Board met to receive an update from Mr. Brookman about the status of discussions and upcoming management meeting with Chevron. On March 15, 2023, Mr. Mount and Mr. Brookman further discussed the management meeting and a potential transaction timeline. On the same date, the PDC Board met again and received an update from J.P. Morgan regarding the conditions of stock markets, generally, and the recent performance of stock prices of PDC and Chevron, in particular, following the recent failure of Silicon Valley Bank and certain other financial institutions. The PDC Board discussed with J.P. Morgan these matters and potential transaction premiums over varying time periods. After discussion, the Board directed Mr. Brookman to emphasize PDC’s intrinsic value in his discussions with Chevron rather than the companies’ relative trading prices. The PDC Board then discussed parties other than Chevron that might be interested in a transaction with PDC and whether an outreach should be made to any such party. After substantial discussion and input from J.P. Morgan and the legal advisors, the PDC Board determined that no outreach should be made at that time because it was still uncertain whether Chevron would make an offer to purchase PDC and because the PDC Board did not want to risk information about a potential transaction becoming publicly known.

On March 16, 2023, Mr. Brookman met for dinner with Mr. Mount and other representatives of Chevron management in advance of a scheduled management presentation the next day.

On March 17, 2023, Mr. Brookman and other members of PDC management gave a presentation to Mr. Mount, Mark Nelson, Chevron’s Vice Chairman and Executive Vice President, Strategy, Policy & Development, Bruce Niemeyer, Chevron’s President, Americas Exploration & Production, and other members of Chevron management, with representatives of Morgan Stanley & Co. LLC (“Morgan Stanley”), Chevron’s financial advisor, in attendance, regarding PDC’s history, operations, financial results, reserves, ESG and sustainability initiatives and other matters. During the meeting, representatives of Chevron indicated that Chevron had been impressed with PDC’s successes and management team, and that an acquisition of PDC would align with Chevron’s focus on generating higher returns while expecting to further lower Chevron’s upstream carbon intensity via practices such as electric drilling and completion equipment, no routine flaring, low emission facility designs, and other best practices. On March 20, 2023, Mr. Mount called Mr. Brookman to tell him that Chevron was impressed with the presentation and remained interested in a transaction. Mr. Mount indicated that due to disruptions in the markets arising from the financial institution failures, Chevron was undertaking further evaluation of the ongoing impact of these developments on the financial markets and general macroeconomic trends and would complete that evaluation prior to proceeding with any written offer to acquire PDC, which could delay the discussions into April.

At a PDC Board meeting held on March 20, 2023, Mr. Brookman gave the board an overview of his communications with Chevron over the preceding week, including Chevron’s timing. These matters were further discussed between Mr. Brookman and Mr. Mount on March 24, 2023, when Mr. Mount told Mr. Brookman that Chevron expected that it would take at least two weeks to further evaluate the impact of the financial institution failures on the broader economy. On March 27, 2023, Mr. Brookman conveyed this information regarding the timeline to the PDC Board. On March 31, 2023, Mr. Mount told Mr. Brookman that Chevron’s analysis of the general economic situation was ongoing.

36

On April 11, 2023, Mr. Brookman told Mr. Mount that the PDC Board needed clarity concerning the prospects for a transaction in light of the delayed timing; Mr. Mount responded that Chevron remained interested in the transaction. Mr. Brookman reported the content of this conversation to the PDC Board at a meeting held on April 11, 2023.

On April 18, 2023, Mr. Brookman met with the CEO of Company A. Mr. Brookman had had conversations with the CEO of Company A from time to time about general issues facing the oil and gas industry, and occasionally about the prospect of a transaction between the two companies, but no specific terms of a transaction were discussed. At this meeting, the CEO of Company A indicated that it was exclusively interested in a potential merger with PDC at that time. Mr. Brookman said that he would discuss the issue with the PDC Board.

Mr. Brookman and Mr. Mount spoke again on April 19, 2023, and Mr. Mount reiterated Chevron’s interest in a transaction notwithstanding the delay in PDC’s expected timing from the parties’ initial/preliminary discussions.

The PDC Board met on April 20, 2023. Mr. Brookman gave an update on the status of discussions with Chevron and also discussed his meeting with the CEO of Company A. Mr. Brookman and Mr. Lauck provided an overview of Company A’s properties and financial characteristics, and noted that PDC shareholders would be expected to own a majority of the combined company in a merger with Company A. The PDC Board directed that management should continue to advance discussions with Company A.

PDC and Company A entered into a mutual confidentiality agreement on April 25, 2023, which included a customary standstill restriction with a customary “fall-away” provision that renders the standstill inapplicable following PDC’s entry into a definitive agreement relating to a merger or other business combination transaction. PDC and Company A also established data rooms on April 29, 2023 to share preliminary diligence materials.

On May 1, 2023, the PDC Board met for a regularly scheduled Audit Committee meeting to approve the company’s first quarter Form 10-Q, at which time Mr. Brookman provided an update regarding the potential Chevron transaction and recent discussions with Company A.

On May 5, 2023, Mr. Mount informed Mr. Brookman that Chevron was in a final review stage prior to making a written offer to acquire PDC. On May 7, 2023, Chevron provided an offer letter to PDC proposing a merger in which each share of PDC stock would be converted into 0.4379 of a share of Chevron stock. The same day, Paul, Weiss, Rifkind, Wharton & Garrison LLP (“Paul Weiss”), legal counsel to Chevron, sent a draft merger agreement to Wachtell.

The PDC Board met on May 8, 2023. Mr. Brookman began the meeting by providing the PDC Board with an update regarding recent communications with Company A, including a planned meeting at which each company’s management would present an overview of its business to the other. Mr. Brookman then described the offer received the preceding day from Chevron. Mr. Lauck provided a preliminary financial analysis of the offer, which equated to an implied PDC share price of $70.16 based on the companies’ most recent closing prices, which represented a 9.0% premium over the trading day close of May 5. Mr. Lauck discussed, among other things, the premium provided by the offer over different trading periods. J.P. Morgan then provided and discussed with the PDC Board certain financial aspects of Chevron’s May 7 offer. Nicole Martinet, PDC’s General Counsel, discussed certain issues raised by the draft merger agreement provided by Paul Weiss, and representatives of Wachtell and DGS participated in that discussion. Mr. Lauck also provided a preliminary financial analysis of a potential transaction with each of Company A and Chevron. Discussion ensued about, among other things, the attractiveness of the Chevron offer and a negotiating strategy for improving it, the prospects and potential benefits of a merger with Company A versus Chevron, the potential timelines for both transactions, and whether a transaction with Company A would facilitate or hinder a potential acquisition of the combined PDC-Company A company by a third party in the future.

37

Mr. Mount and Mr. Brookman had conversations on May 9 and May 10 during which they discussed, among other things, due diligence matters, the proposed transaction timeline and the status of the merger agreement.

The PDC Board met again on May 11, 2023. Mr. Lauck and other members of PDC management provided a more detailed analysis of Company A, including its operations, recent performance, guidance, ESG attributes, reserves, well performance, initial net asset value estimates and capital structure. This presentation also included a preliminary valuation analysis of Company A based on stock price performance, financial forecasts and discounted cash flows, as well as several next steps planned as part of the Company A valuation assessment process. J.P. Morgan then provided and discussed with the PDC Board certain financial aspects of the May 7 Chevron offer and certain preliminary financial analyses regarding a potential transaction with Company A. The PDC Board then discussed potential positive and negative factors associated with a transaction with Company A, including the potential for an increased valuation of the combined company due to its greater scale but also the possibility that the anticipated levels of synergies from a merger may not materialize given the geographic dispersion of the companies’ properties. It then compared a potential transaction with Company A to one with Chevron, determining that a Chevron transaction would present less execution risk and would have greater potential for maximizing value for PDC shareholders on a risk-adjusted basis. Following discussion, the PDC Board directed management to prioritize discussions with Chevron, but also to continue the valuation assessment process with Company A in light of the possibility that no acceptable deal would be reached with Chevron. The PDC Board also instructed management to respond to Chevron’s proposal by proposing an implied per share price in the mid-$70s and gave Mr. Brookman authority to negotiate in the $70-$75 per share price range. With the participation of Wachtell, DGS and J.P. Morgan, the PDC Board and management then revisited its prior discussions regarding a potential outreach to one or more third parties. After discussion, the PDC Board concluded that (i) it was unlikely that any party would be willing to offer terms that would be superior to those offered by Chevron and (ii) the terms of the merger agreement with Chevron, assuming one was entered into, would not prevent a third party from making an offer for PDC after the merger agreement was signed and announced. Therefore, the PDC Board determined an outreach at this time would create risks, particularly in terms of confidentiality, that would likely outweigh any potential benefits.

On May 12, 2023, Mr. Brookman spoke to Mr. Mount and suggested that Chevron conduct additional valuation due diligence on PDC’s production, financial model and inventory with a view toward improving its offer. Mr. Brookman also communicated that the PDC Board wanted an offer that reflected a mid-$70s per share price for PDC stock. Finally, Mr. Brookman noted that although the initial draft of the merger agreement was generally constructive, certain terms were not acceptable to PDC. With respect to the exchange ratio, Mr. Mount and Mr. Brookman discussed how the trading prices of the companies’ stock over time would affect the acceptability to each party of a given ratio. Without precisely defining a minimum per share price or a maximum premium, they also discussed that pricing parameters that would result in at least a minimum implied per share price for PDC stock, but that would not exceed a maximum spot price premium, would likely be acceptable to both parties. They discussed that a number of matters outside the control of either party, including the relative trading prices of each company’s shares, would influence the ultimate exchange ratio, with Mr. Brookman emphasizing PDC’s view that PDC’s intrinsic value should be a significant driver in any such discussions and Mr. Mount emphasizing the significance of, and consistency demonstrated by, Chevron’s track record on capital discipline in M&A activity.

On May 14, 2023, Wachtell provided a revised draft of the merger agreement to Paul Weiss. This draft reflected a number of proposed changes, including a reduced break-up fee payable by PDC if the agreement were terminated in certain circumstances, a carveout from the definition of the term “Company Material Adverse Effect” for adverse developments in the Colorado regulatory environment and cutbacks to the interim operating covenants to which PDC would be subject during the pendency of the merger. The draft also included a substantially stronger covenant on the part of Chevron to obtain necessary regulatory approvals and PDC’s proposal that a “reverse” break-up fee would be paid to PDC in the event the merger agreement was terminated due to failure to obtain such approvals.

38

At a meeting of the PDC Board held on May 15, 2023, Mr. Brookman reported to the board the substance of his May 12 conversation with Mr. Mount, including on pricing parameters. Ms. Martinet then highlighted certain issues in the draft merger agreement that were being negotiated with Chevron and Paul Weiss, including Chevron’s regulatory approval covenant, the inclusion and size of the break-up fee, PDC’s interim operating covenants and provisions regarding retention of PDC employees. The PDC Board then discussed potential resolutions of certain of these issues. After this meeting, Mr. Brookman spoke with Mr. Mount, and they agreed the parties might be able to determine a mutually-acceptable exchange ratio at the end of the current week. Mr. Brookman emphasized to Mr. Mount the importance of Chevron’s regulatory approval covenant and also noted certain outstanding employee-related issues.

On May 17, 2023, Mr. Mount and Mr. Brookman further discussed certain merger agreement issues, the timing of the transaction and, assuming a deal were to be reached, the external and internal communications plan regarding the transaction. Later that day, at a meeting attended by members of Chevron’s management, including Pierre Breber, Chevron’s Vice President and Chief Financial Officer, and representatives of Morgan Stanley, representatives of Chevron answered reverse diligence questions from representatives of PDC, with the assistance of J.P Morgan, Wachtell and DGS, regarding Chevron’s businesses, properties and financial results and condition, and Chevron formally engaged Evercore Group L.L.C. with respect to the potential transaction with PDC to provide additional financial advice in connection with the merger agreement.

On May 18, 2023, Paul Weiss circulated a revised draft of the merger agreement to Wachtell.

On May 19, 2023, Mr. Brookman and Mr. Mount discussed the merger agreement, including certain employee-related matters. In a subsequent conversation after the close of trading on that day, Mr. Mount called Mr. Brookman to communicate Chevron’s updated proposed exchange ratio of 0.4638, which implied a per share price for PDC stock of $72.00 based on the companies’ closing trading prices as of May 19, 2023 which represented a 10.6% premium over the trading day close price and 14% premium over 10-day trading price, noting that it fell within the previously discussed pricing parameters for both sides. Mr. Mount said that this was Chevron’s best and final offer. Mr. Brookman indicated that that exchange ratio might be acceptable but that PDC would want the ability to pay a $1.50 special dividend to its shareholders prior to the closing of the merger. Mr. Mount discussed this proposal with other members of Chevron’s management, and then called Mr. Brookman to tell him that Chevron would not accept the special dividend proposal and to reiterate that the 0.4638 exchange ratio represented Chevron’s best and final offer. Mr. Brookman said that he would convey that message to the PDC Board. On the same day, PDC formally engaged PJT Partners to provide supplementary financial advisory services to PDC in connection with the potential transaction with Chevron.

The PDC Board met on the evening of May 19, 2023. Mr. Brookman described to the board the substance of his conversations with Mr. Mount. Ms. Martinet and Wachtell described the remaining open issues in the merger agreement. J.P. Morgan then provided and discussed with the PDC Board certain financial aspects of Chevron’s offer. Discussion ensued regarding the attractiveness of the offer and the likelihood that Chevron would improve it. After this discussion, the PDC Board instructed Mr. Brookman to tell Mr. Mount that PDC would move forward with the proposed exchange ratio, subject to satisfactory resolution of the final provisions of the draft merger agreement. Mr. Brookman conveyed this message to Mr. Mount after the meeting.

Wachtell, DGS and PDC continued to negotiate the terms of the merger agreement on May 19 through 21, 2023 with Paul Weiss and Chevron. PDC agreed to the elimination of the reverse break-up fee and Chevron agreed to certain changes to strengthen its covenant to obtain regulatory approvals. The parties also reached agreement on PDC’s interim operating covenants, the employee-related matters and the size of the break-up fee potentially payable by PDC in certain circumstances.

On May 21, 2023, Mr. Brookman spoke with Michael Wirth, Chairman of the Chevron Board and Chevron’s Chief Executive Officer, where Mr. Wirth shared Chevron’s view of PDC’s complementary culture, low carbon operations, and shareholder returns focus. Additionally, Mr. Wirth and Mr. Brookman discussed their respective visions for the future combined asset base of the two companies and the benefits of the transaction to both companies’ shareholders.

39

The merger agreement was in substantially final form by the afternoon of May 21, 2023, when the PDC Board met to consider approval of the merger, with representatives of Wachtell, DGS, J.P. Morgan and PJT Partners in attendance. Representatives of Wachtell discussed the PDC Board’s fiduciary duties in the context of the merger and the merger agreement, and, together with Ms. Martinet, summarized the terms of the merger agreement. Representatives of J.P. Morgan then reviewed with the PDC Board its financial analyses of the proposed transaction at the agreed upon 0.4638 exchange ratio. Following discussion, J.P. Morgan rendered its oral opinion to the PDC Board, which was subsequently confirmed by delivery of a written opinion, dated May 21, 2023, to the effect that, as of such date and based upon and subject to the factors, assumptions, qualifications and any limitations set forth in its written opinion, the merger consideration to be paid to the holders of PDC common stock in the proposed merger was fair, from a financial point of view, to such holders. See the section entitled “—Opinion of PDC’s Financial Advisor” for more information. A representative of PJT Partners also addressed questions posed by the PDC Board relating to the transaction as well as market and investor relations considerations.

After considering the proposed terms of the transaction with Chevron, and taking into consideration the matters discussed during that meeting and prior meetings of the PDC Board, including the factors described above and under the section entitled “—Recommendation of the PDC Board and Reasons for the Merger,” the PDC Board unanimously (1) declared that the merger agreement and the transactions contemplated thereby (including the merger), are fair to, and in the best interests of, PDC’s stockholders, (2) approved and declared advisable the merger agreement and the transactions contemplated thereby (including the merger), (3) directed that the adoption of the merger agreement be submitted to a vote at a meeting of the PDC stockholders and (4) resolved (subject to certain exceptions set forth in the merger agreement) to recommend the approval and adoption of the merger agreement and the transactions contemplated thereby (including the merger) by the PDC stockholders.

Following the PDC Board meeting, PDC and Chevron executed the merger agreement.

Prior to the opening of trading on May 22, 2023, Chevron and PDC issued a joint press release announcing entry into the merger agreement.

Chevron’s Rationale for the Transaction

Chevron believes that the merger with PDC presents Chevron with the opportunity to:

PDC Board’s Recommendations and Its Reasons for the Transaction

By unanimous vote, the PDC Board, at a meeting held on May 21, 2023, (a) declared that the merger agreement and the transactions contemplated thereby (including the merger), are fair to, and in the best interests of, PDC’s stockholders, (b) approved and declared advisable the merger agreement and the transactions contemplated thereby (including the merger), (c) directed that the adoption of the merger agreement be submitted to a vote at a meeting of the PDC stockholders and (d) resolved (subject to certain exceptions set forth in the merger agreement) to recommend the approval and adoption of the merger agreement and the transactions contemplated thereby (including the merger) by the PDC stockholders. The PDC Board unanimously recommends that PDC stockholders vote “FOR” the merger proposal, “FOR” the non-binding merger-related compensation proposal and “FOR” the adjournment proposal.

40

In reaching its determinations and recommendations, the PDC Board consulted with company management and financial and legal advisors and considered a range of factors and scenarios, as discussed below. Factors that weighed in favor of the merger include:

In the course of its deliberations, the PDC Board also considered a variety of risks and other potentially negative factors, including the following:

The PDC Board believed that, overall, the potential benefits of the merger to PDC stockholders outweighed the potential risks and uncertainties of the merger.

In addition, the PDC Board was aware of and considered that PDC’s directors and executive officers may have interests in the merger that may be different from, or in addition to, their interests as stockholders of PDC generally, as described below under the heading “—Interests of Directors and Executive Officers of PDC in the Merger” beginning on page [     ].

The foregoing discussion of factors considered by the PDC Board is not intended to be exhaustive, but it includes material factors considered by the PDC Board. In light of the variety of factors considered in connection

45

with its evaluation of the merger, the PDC Board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determinations and recommendations. Moreover, each member of the PDC Board applied his or her own personal business judgment to the process and may have given different weight to different factors. The PDC Board did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination. The PDC Board based its recommendation on the entirety of the information presented.

Opinion of PDC’s Financial Advisor

Pursuant to an engagement letter dated February 22, 2023, PDC retained J.P. Morgan as its financial advisor in connection with a potential transaction (including the proposed merger). At the meeting of the PDC Board on May 21, 2023, J.P. Morgan rendered its oral opinion to the PDC Board, which was subsequently confirmed by delivery of a written opinion, dated May 21, 2023, to the effect that, as of such date and based upon and subject to the factors, assumptions, qualifications and any limitations set forth in its written opinion, the merger consideration to be paid to the holders of PDC common stock in the proposed merger was fair, from a financial point of view, to such holders.

The full text of the written opinion of J.P. Morgan dated May 21, 2023, which sets forth, among other things, the assumptions made, matters considered and qualifications and any limitations on the opinion and the review undertaken by J.P. Morgan in connection with rendering its opinion, is attached as Annex B to this proxy statement/prospectus and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. PDC’s stockholders are urged to read the opinion carefully and in its entirety. J.P. Morgan’s opinion was addressed to the PDC Board (in its capacity as such) in connection with and for the purposes of its evaluation of the proposed merger, was directed only to the merger consideration to be paid to the holders of PDC common stock in the proposed merger and did not address any other aspect of the proposed merger or the other transactions contemplated by the merger agreement. J.P. Morgan was not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of PDC or any alternative transaction. The issuance of J.P. Morgan’s opinion was approved by a fairness committee of J.P. Morgan. The opinion does not constitute a recommendation to any stockholder of PDC as to how such stockholder should vote with respect to the proposed merger or any other matter.

In arriving at its opinion, J.P. Morgan, among other things:

46

In addition, J.P. Morgan held discussions with certain members of the management of PDC and Chevron with respect to certain aspects of the proposed merger, and the past and current business operations of PDC, the financial condition and future prospects and operations of PDC, and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by PDC and Chevron or otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not independently verify any such information or its accuracy or completeness and, pursuant to J.P. Morgan’s engagement letter with PDC, J.P. Morgan did not assume any obligation to undertake any such independent verification. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did J.P. Morgan evaluate the solvency of PDC or Chevron under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to J.P. Morgan or derived therefrom, J.P. Morgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of PDC to which such analyses or forecasts relate. For purposes of J.P. Morgan’s opinion and financial analyses, the PDC Board directed J.P. Morgan to apply a 20% weighting to the results of J.P. Morgan’s financial analyses using the “Management Outlook + LT $55 Flat Case,” and a 40% weighting to each of the results of J.P. Morgan’s financial analyses using the “Management Outlook + LT $70 Flat Case” and the “Strip Case” and to use such weighted results for purposes of its opinion and certain financial analyses. J.P. Morgan expresses no view as to such analyses or forecasts or the assumptions on which they were based or as to such weightings or directions. J.P. Morgan also assumed that the proposed merger and the other transactions contemplated by the merger agreement will have the tax consequences described in discussions with, and materials furnished to J.P. Morgan by, representatives of PDC, and will be consummated as described in the merger agreement, and that the definitive merger agreement will not differ in any material respects from the draft thereof furnished to J.P. Morgan. J.P. Morgan also assumed that the representations and warranties made by PDC and Chevron and Merger Sub in the merger agreement and the related agreements were and will be true and correct in all respects material to J.P. Morgan’s analysis. J.P. Morgan is not a legal, regulatory or tax expert and relied on the assessments made by advisors to PDC with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the proposed merger will be obtained without any adverse effect on PDC or on the contemplated benefits of the proposed merger.

J.P. Morgan’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of such opinion. J.P. Morgan’s opinion noted that subsequent developments may affect J.P. Morgan’s written opinion dated May 21, 2023, and that J.P. Morgan does not have any obligation to update, revise, or reaffirm such opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the merger consideration to be paid to the holders of PDC common stock in the proposed merger, and J.P. Morgan has expressed no opinion as to the fairness of any consideration to be paid in connection with the proposed merger to the holders of any other class of securities, creditors or other constituencies of PDC or as to the underlying decision by PDC to engage in the proposed merger. Furthermore, J.P. Morgan expressed no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the proposed merger, or any class of such persons relative to the merger consideration to be paid to the holders of PDC common stock in the proposed merger or with respect to the fairness of any such compensation. J.P. Morgan expressed no opinion as to the price at which PDC common stock or Chevron common stock will trade at any future time.

The terms of the merger agreement, including the merger consideration, were determined through arm’s length negotiations between PDC and Chevron, and the decision to enter into the merger agreement was solely that of the PDC Board. J.P. Morgan’s opinion and financial analyses were only one of the many factors considered by the PDC Board in its evaluation of the proposed merger and should not be viewed as determinative of the views of the PDC Board or management with respect to the proposed merger or the merger consideration.

47

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methodologies in rendering its opinion to the PDC Board on May 21, 2023 and in the financial analyses presented to the PDC Board on such date in connection with the rendering of such opinion. The following is a summary of the material financial analyses utilized by J.P. Morgan in connection with rendering its opinion to the PDC Board and contained in the presentation delivered to the PDC Board on such date in connection with the rendering of such opinion and does not purport to be a complete description of the analyses or data presented by J.P. Morgan. Certain of the summaries of the financial analyses include information presented in tabular format. The tables are not intended to stand alone, and in order to more fully understand the financial analyses used by J.P. Morgan, the tables must be read together with the full text of each summary. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s analyses.

Selected Public Trading Multiples

Using publicly available information, J.P. Morgan compared selected financial data of PDC with similar data for certain selected publicly traded companies engaged in businesses which J.P. Morgan judged to be sufficiently analogous to those engaged in by PDC, based on J.P. Morgan’s experience and familiarity with the industries in which PDC operates.

The companies selected by J.P. Morgan were:

None of the selected companies reviewed is identical or directly comparable to PDC, and certain of these companies may have characteristics that are materially different from those of PDC. However, these companies were selected, among other reasons, because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered sufficiently similar in certain respects to PDC. The analysis necessarily involves complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies differently than they would affect PDC.

Using publicly available information as of May 19, 2023, J.P. Morgan calculated and compared for each selected company listed above and for PDC:

48

Based on the results of this analysis and other factors which J.P. Morgan considered appropriate based on its experience and professional judgment, J.P. Morgan selected multiple reference ranges of 2.50x – 3.50x and 2.25x – 3.25x for firm value to estimated 2023 and 2024 EBITDAX, respectively, and 1.75x – 3.75x and 1.50x – 3.50x for equity value to estimated 2023 and 2024 operating cash flow, respectively.

After applying such ranges to the appropriate metrics for PDC based on PDC management’s Consensus Case at the direction of PDC management, the analysis indicated the following ranges of implied equity values per share of PDC common stock (resulting per share values were in all cases rounded to the nearest $0.25 per share):

PDC Implied Equity Value Per Share Range

The ranges of implied equity value per share were compared to (i) the closing price per share of PDC common stock of $65.12 on May 19, 2023 and (ii) the implied value of the merger consideration of $72.00 per share of PDC common stock. The implied value of the merger consideration of $72.00 as used throughout this summary was calculated by multiplying the exchange ratio of 0.4638 shares of Chevron common stock by $155.23, the closing price per share of Chevron common stock on May 19, 2023.

Selected Transaction Multiples Analysis

Using publicly available information, J.P. Morgan examined selected corporate transactions in the energy exploration and production (“E&P”) sector.

Using publicly available information, J.P. Morgan calculated, for each of the selected transactions listed below, the transaction value as a multiple of EBITDAX over the next twelve months (“NTM EBITDAX”). J.P. Morgan reviewed the following corporate transactions in the E&P sector (buyer / seller):

49

Based on the results of this analysis and other factors which J.P. Morgan considered appropriate based on its experience and professional judgment, J.P. Morgan selected a multiple reference range for firm value to NTM EBITDAX of 2.50x – 4.50x. For purposes of such calculation, NTM EBITDAX for PDC reflected the Consensus Case as directed by PDC management.

After applying this range to the appropriate metrics for PDC based on the Consensus Case as directed by PDC management, this analysis indicated the following range of implied equity values per share of PDC common stock (resulting per share values were in all cases rounded to the nearest $0.25 per share):

PDC Implied Equity Value Per Share Range

The range of implied equity values per share were compared to (i) the closing price per share of PDC common stock of $65.12 on May 19, 2023 and (ii) the implied value of the merger consideration of $72.00 per share of PDC common stock.

Discounted Cash Flow Analysis

J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining an implied equity value per share for PDC common stock based on three commodity price and activity cases provided to J.P. Morgan by PDC management (which cases we refer to herein as the “Management Outlook + LT $55 Flat Case,” the “Management Outlook + LT $70 Flat Case” and the “Strip Case”).

J.P. Morgan calculated the present value, as of April 30, 2023, of unlevered free cash flows that PDC was forecasted to generate during fiscal years 2023 through 2031 based upon each of the Management Outlook + LT $55 Flat Case, the Management Outlook + LT $70 Flat Case and the Strip Case. J.P. Morgan also calculated a range of terminal asset values for PDC at the end of the nine-year period ending 2031 by applying a terminal EBITDAX multiple range of 2.00x to 3.00x, which terminal multiple range was reviewed and approved by PDC management, to the unlevered free cash flow of PDC during the final year of the nine-year period for each such case.

The unlevered free cash flows and the range of terminal asset values were then discounted to present values using a range of discount rates from 10.25% to 11.25% for each case, which range was chosen by J.P. Morgan based upon an analysis of the weighted average cost of capital of PDC, and then were divided by the number of fully diluted shares of PDC outstanding (approximately 88.2 million, as provided by PDC management) to arrive at a range of implied equity values per share of PDC common stock for each of the Management Outlook + LT $55 Flat Case, the Management Outlook + LT $70 Flat Case and the Strip Case. At the direction of the PDC Board, J.P. Morgan then applied a 20% weighting to the results of its discounted cash flow analysis using the Management Outlook + LT $55 Flat Case and a 40% weighting to each of the results of its discounted cash flow analyses using the Management Outlook + LT $70 Flat Case and the Strip Case, which indicated a range of implied equity value of $64.75 to $82.00 per share of PDC common stock (rounded to the nearest $0.25 per

50

share) and which range, at the direction of the PDC Board, J.P. Morgan considered for purposes of its opinion. The range of implied equity value per share was compared to (i) the closing price per share of PDC common stock of $65.12 on May 19, 2023 and (ii) the implied value of the merger consideration of $72.00 per share of PDC common stock.

52-Week Historical Trading Range

For reference only and not as a component of its fairness analysis, J.P. Morgan reviewed the trading range for the PDC common stock for the 52-week period ended May 19, 2023, which was $52.19 per share to $86.18 per share, and compared that range to (i) the closing price per share of PDC common stock of $65.12 on May 19, 2023 and (ii) the implied value of the merger consideration of $72.00 per share of PDC common stock.

Analyst Price Target

For reference only and not as a component of its fairness analysis, J.P. Morgan reviewed certain publicly available equity research analyst price targets for the PDC common stock available as of May 19, 2023, and noted that the range of such price targets was $77.00 per share to $100.00 per share and compared that range to (i) the closing price per share of PDC common stock of $65.12 on May 19, 2023 and (ii) the implied value of the merger consideration of $72.00 per share of PDC common stock.

Miscellaneous

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above were merely utilized to create points of reference for analytical purposes and should not be taken to be the view of J.P. Morgan with respect to the actual value of PDC. The order of analyses described does not represent the relative importance or weight given to those analyses by J.P. Morgan. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion.

Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be acquired or sold. None of the selected companies reviewed as described in the above summary is identical to PDC, and none of the selected transactions reviewed was identical to the proposed merger. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of PDC. The transactions selected were similarly chosen because their participants, size and other factors, for purposes of J.P. Morgan’s analysis, may be considered similar to the proposed merger. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to PDC and the transactions compared to the proposed merger.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive

51

and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, and valuations for corporate and other purposes. J.P. Morgan was selected to advise PDC with respect to the proposed merger on the basis of, among other things, such experience and its qualifications and reputation in connection with such matters and its familiarity with PDC and the industries in which it operates.

For services rendered in connection with the proposed merger and the delivery of its opinion, PDC has agreed to pay J.P. Morgan a transaction fee of 0.4% of the merger consideration payable in the proposed merger plus, in the event that such consideration ultimately exceeds $74.00 per share of PDC common stock, an additional 1.0% of any incremental merger consideration paid by Chevron to PDC’s stockholders in excess of $74.00 per share, except that the aggregate transaction fee will not exceed 0.48% of the merger consideration payable in the proposed merger. Based on the exchange ratio of 0.4638 of a share of Chevron common stock and the $155.23 closing price per share of Chevron common stock on May 19, 2023, J.P. Morgan’s transaction fee would be approximately $30.55 million, of which $3.0 million became payable by PDC to J.P. Morgan in connection with J.P. Morgan’s delivery of its opinion and the balance of which will become payable upon the closing of the proposed merger. In addition, PDC has agreed to reimburse J.P. Morgan for its expenses incurred in connection with its services, including the fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities arising out of J.P. Morgan’s engagement. During the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with PDC and Chevron, for which J.P. Morgan and its affiliates have received compensation of approximately $2.2 million and $2.8 million from PDC and Chevron, respectively. Such services during such period have included acting as joint lead arranger and joint lead bookrunner on PDC’s credit facility that closed in November 2021, acting as financial advisor to a subsidiary of Chevron on a sale transaction in August 2021, acting as joint dealer manager on Chevron’s bond tender in October 2021, acting as joint lead arranger and joint lead bookrunner for a revolving credit facility of a subsidiary of Chevron in December 2021 and acting as joint lead arranger for a term loan for a subsidiary of Chevron in November 2021. In addition, J.P. Morgan’s commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of PDC, for which it receives customary compensation or other financial benefits. In addition, J.P. Morgan and its affiliates hold, on a proprietary basis, less than 1% of the outstanding common stock of each of PDC and Chevron. In the ordinary course of their businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of PDC or Chevron for its own account or for the accounts of customers and, accordingly, J.P. Morgan may at any time hold long or short positions in such securities or other financial instruments.

PDC Unaudited Prospective Financial Information

PDC does not, as a matter of course, publicly disclose long-term consolidated forecasts as to future performance, earnings or other results given, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. In connection with the PDC Board’s consideration of the transaction, PDC’s management prepared certain unaudited financial projections regarding PDC’s future performance for the years 2023 through 2031 on a standalone basis without giving effect to the merger (the “PDC management forecast”), and provided the PDC management forecast to the PDC Board and to PDC’s financial advisor for its use in connection with its financial analyses (see the sections described above in this proxy statement/prospectus entitled “The Merger—Opinion of PDC’s Financial Advisor” beginning on page [    ] of this proxy statement/prospectus). The PDC management forecast is based upon the internal financial model that PDC has historically used in connection with strategic planning.

The summaries of these projections are being included in this proxy statement/prospectus to give PDC’s stockholders access to non-public information that was provided to the PDC Board and PDC’s financial advisor in the course of evaluating the proposed merger, and are not intended to influence your decision whether to vote in favor of the merger proposal or any other proposal at the special meeting. The inclusion of this information should not be regarded as an indication that any of PDC or its advisors or other representatives or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future

52

performance or events, or that it should be construed as financial guidance, and such summary projections set forth below should not be relied on as such.

While presented with numeric specificity, the PDC management forecast reflects numerous estimates and assumptions that are inherently uncertain and may be beyond the control of PDC, including, among others, PDC’s assumptions about energy markets, production and sales volume levels, levels of oil, natural-gas and NGL reserves, operating results, competitive conditions, technology, availability of capital resources, levels of capital expenditures, contractual obligations, supply and demand for, the price of, and the commercialization and transporting of oil, natural gas, NGLs and other products or services, geopolitical and regulatory risks, and other matters described in the sections entitled “Cautionary Note Regarding Forward-Looking Statements”, “Where You Can Find More Information”, and “Risk Factors”, beginning on pages [    ], [    ] and [    ], respectively. The PDC management forecast reflects both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. PDC can give no assurance that the PDC management forecast and the underlying estimates and assumptions will be realized. In addition, since the PDC management forecast covers multiple years, such information by its nature becomes more speculative with each successive year. This information constitutes “forward-looking statements” and actual results may differ materially and adversely from those projected.

The PDC management forecast was not prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information. The prospective financial information included in this document has been prepared by, and is the responsibility of, PDC’s management. PricewaterhouseCoopers LLP has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying prospective financial information and accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The reports of PricewaterhouseCoopers LLP incorporated by reference into this proxy statement/prospectus relate to Chevron’s and PDC’s previously issued financial statements. They do not extend to the prospective financial information and should not be read to do so.

Furthermore, the PDC management forecast does not take into account any circumstances or events occurring after the date it was prepared. PDC can give no assurance that, had the PDC management forecast been prepared as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. Except as required by applicable securities laws, PDC does not intend to, and disclaims any obligation to, make publicly available any update or other revision to the PDC management forecast to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error or to reflect changes in general economic or industry conditions. The PDC management forecast does not take into account all the possible financial and other effects on PDC of the merger, the effect on PDC of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the PDC management forecast does not take into account the effect on PDC of any possible failure of the merger to occur. None of PDC or its affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any PDC stockholder or other person regarding PDC’s ultimate performance compared to the information contained in the PDC management forecast or to the effect that the forecasted results will be achieved. The inclusion of the PDC management forecast herein should not be deemed an admission or representation by PDC or its advisors or any other person that it is viewed as material information of PDC, particularly in light of the inherent risks and uncertainties associated with such forecasts.

53

In light of the foregoing, and considering that the special meeting will be held several months after the PDC management forecast was prepared, as well as the uncertainties inherent in any forecasted information, PDC stockholders are cautioned not to place undue reliance on such information, and PDC urges all PDC stockholders to review PDC’s most recent SEC filings for a description of PDC’s reported financial results. See “Where You Can Find More Information” beginning on page [    ].

Certain Assumptions

In preparing the prospective financial and operating information for PDC described below, the management team of PDC used the following price assumptions, which are based on: (i) oil and gas strip pricing as of May 17, 2023 (which we refer to as “Strip”), (ii) Wall Street consensus pricing as of May 17, 2023 (which we refer to as “Consensus”), (iii) the internal pricing assumptions of management for the years 2023-2025 and flat oil and gas prices of $55/bbl and $3.00/MMbtu, respectively, for the years 2026-2031 (which we refer to as “Management Outlook + LT $55 Flat”) and (iv) the internal pricing assumptions of management for the years 2023-2025 and flat oil and gas prices of $70/bbl and $4.25/MMbtu, respectively, for the years 2026-2031 (which we refer to as “Management Outlook + LT $70 Flat”). As further described under “Opinion of PDC’s Financial Advisor” beginning on page [    ], for purposes of J.P. Morgan’s opinion and financial analyses, the PDC Board directed J.P. Morgan to apply a 20% weighting to the results of J.P. Morgan’s financial analyses using the “Management Outlook + LT $55 Flat Case,” and a 40% weighting to each of the results of J.P. Morgan’s financial analyses using the “Management Outlook + LT $70 Flat Case” and the “Strip Case” and to use such weighted results for purposes of its opinion and certain financial analyses.

Additional detail about the specific commodity price assumptions underlying the Strip, Consensus, Management Outlook + LT $55 Flat and Management Outlook + LT $70 Flat commodity price decks is set forth in the tables below.

54

In addition to certain assumptions with respect to commodity prices, the PDC management forecast is based on various other assumptions, including, but not limited to, assumptions regarding the continuing nature of ordinary course operations that may be subject to change.

The following table summarizes the PDC management forecast as of an April 30, 2023 valuation date for the fiscal years 2023 through 2031 ($ in millions):

PDC does not intend to update or otherwise revise the above unaudited financial and operating forecasts to reflect circumstances existing after the date when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying such unaudited financial and operating forecasts are no longer appropriate, except as may be required by applicable law.

Interests of Directors and Executive Officers of PDC in the Merger

In considering the recommendation of the PDC Board that PDC stockholders approve the transaction and vote in favor of the merger proposal and the merger-related compensation proposal, PDC stockholders should be aware that the executive officers and directors of PDC have certain interests in the merger that are or may be different from, or in addition to, the interests of PDC’s stockholders generally. The PDC Board was aware of these interests and considered them, among other matters, in evaluating and approving the merger agreement, and in making its recommendation that PDC stockholders adopt the merger agreement.

These interests are described in more detail below. The merger will be a “change in control” for purposes of the PDC executive compensation plans and agreements described below.

For purposes of this disclosure, the executive officers of PDC are Barton R. Brookman, President and Chief Executive Officer, R. Scott Meyers, Executive Vice President–Chief Financial Officer, Lance A. Lauck, Executive Vice President–Corporate Development and Strategy, Nicole L. Martinet, Senior Vice President –General Counsel and Secretary, David J. Lillo, Senior Vice President–Operations, and Sandra E. Jacoby, Senior

55

Vice President–Corporate Administration. Although Ms. Jacoby is an executive officer of PDC, she is not a named executive officer and therefore a quantification of her merger-related compensation is included within the narrative below and is not included in the section below entitled “Quantification of Payments and Benefits to PDC’s Named Executive Officers.”

Certain Assumptions

Except as otherwise specifically noted, for purposes of quantifying the potential payments and benefits to Ms. Jacoby and our non-employee directors described in this section, the following assumptions were used:

The amounts indicated below are estimates based on multiple assumptions (including the assumptions described above) that may or may not actually occur or be accurate on the relevant date, and do not reflect certain compensation actions that may occur before completion of the transaction. Accordingly, the actual amounts received may differ from the estimates set forth below.

Treatment of PDC Equity Awards

PDC SARs. At the effective time of the merger, each outstanding PDC SAR, whether or not vested, will be converted into a Chevron SAR, on the same terms and conditions as were applicable under such PDC SAR immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded down to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC SAR immediately prior to the effective time of the merger by (ii) the exchange ratio. The exercise price per share of Chevron common stock subject to any such Chevron SAR at and after the effective time of the merger will be an amount (rounded up to the nearest one hundredth of a cent) equal to (i) the exercise price per share of PDC common stock subject to such PDC SAR immediately prior to the effective time of the merger divided by (ii) the exchange ratio.

PDC RSU Awards. At the effective time of the merger, each outstanding PDC RSU award, whether or not vested, will be converted into a Chevron RSU award, on the same terms and conditions as were applicable under such PDC RSU award immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares PDC common stock subject to such PDC RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

PDC PSU Awards. At the effective time of the merger, each outstanding PDC PSU award, whether or not vested, will be treated as follows:

56

PDC Director RSU Awards. At the effective time of the merger, each outstanding PDC Director RSU award, whether or not vested, will be converted into the right to receive, within five business days of the completion of the merger, the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC Director RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

Dividend Equivalent Rights. Any amounts relating to dividend equivalent rights granted with respect to the foregoing PDC equity awards that are accrued but unpaid as of the completion of the merger will carry over and will be paid if required by and in accordance with the terms and conditions as were applicable to such equity award immediately prior to the completion of the merger (or, in the case of PDC PSU awards granted in 2021 and PDC Director RSU awards, will be paid within five business days of the completion of the merger).

Accelerated Vesting of Equity Awards Upon a Qualifying Termination. Each of the PDC executive officers holds unvested PDC RSU awards and unvested PDC PSU awards, which awards (other than PDC PSU awards granted in 2021) will convert into Chevron RSU awards at the effective time of the merger, as described above. The terms of such unvested PDC equity awards provide that such awards will vest in full immediately upon the holder’s involuntary termination of employment without “cause” or resignation for “good reason” (as such terms are defined in the applicable award agreements). The termination vesting provisions applicable to unvested PDC equity awards held by executive officers will continue to apply to such awards after such awards are converted into Chevron equity awards at the effective time of the merger.

See “—Quantification of Payments and Benefits to PDC’s Named Executive Officers” below for an estimate of the value of each PDC named executive officer’s unvested PDC equity awards. Based on the assumptions described above under “—Certain Assumptions,” and assuming for purposes of this disclosure that the performance goals applicable to Ms. Jacoby’s PDC PSU award, which was granted in 2023, are achieved at a performance level of 250% (the actual level of performance as of the assumed effective time of June 15, 2023), the estimated value of unvested equity awards held by Ms. Jacoby (including the payment of accrued but unpaid dividend equivalent rights) is: unvested PDC RSU awards—$831,913; and unvested PDC PSU award—$441,017. Based on the assumptions described above under “—Certain Assumptions,” the estimated aggregate

57

value of unvested PDC Director RSU awards held by all six non-employee directors of PDC (including the payment of accrued but unpaid dividend equivalent rights) is $1,178,524.

Executive Severance Arrangements

Executive Severance Plan

Each executive officer other than Mr. Lauck is a participant in the PDC Executive Severance Compensation Plan, as amended and restated on June 25, 2020 (the “Severance Plan”). The Severance Plan provides that, in the event of a qualifying termination of employment (defined as an involuntary termination without cause or resignation for good reason (as such terms are defined in the Severance Plan)) of the executive officer during the period beginning six months before and ending two years following a change in control, the executive officer will be entitled to receive (1) cash severance equal to 2.5 times (or, in the case of Mr. Brookman, 3 times) the sum of the executive officer’s highest base salary during the two years preceding the change in control plus the highest target bonus percentage established for the executive officer for the year in which the termination occurs or the year immediately preceding the year in which the termination occurs (such combination of base salary and annual target bonus, the “Annual Cash Compensation”), (2) a prorated annual bonus based on target performance for the year of termination, and (3) payment or reimbursement by PDC for monthly premiums for continued group health coverage for the executive officer and his or her dependents for up to 36 months.

Lance A. Lauck Agreement

PDC is party to an amended and restated employment agreement with Mr. Lauck, dated as of August 4, 2020 (the “Lauck Agreement”). Pursuant to the Lauck Agreement, if Mr. Lauck experiences a qualifying termination of employment (defined as an involuntary termination without cause or resignation for good reason (as such terms are defined in the Lauck Agreement)) during the period beginning six months before and ending two years following a change in control, he will be entitled to receive (1) cash severance equal to three times the sum of Mr. Lauck’s highest base salary during the two years preceding the change in control plus the highest bonus paid to Mr. Lauck in that same period (such combination of base salary and bonus paid, the “Lauck Annual Cash Compensation”), and (2) payment or reimbursement by PDC for monthly premiums for continued group health coverage for Mr. Lauck and his dependents for up to 36 months.

For a description of the additional provisions governing treatment of unvested PDC RSU awards and unvested PDC PSU awards upon an executive officer’s qualifying termination, see the section entitled “—Treatment of PDC Equity Awards—Accelerated Vesting of Equity Awards Upon a Qualifying Termination” above.

Release of Claims and Restrictive Covenants

The foregoing payments to each of the executive officers are contingent on the executive officer executing and not revoking a release of claims agreement with PDC. Each executive officer is also prohibited for a period of one year following termination of employment from competing with PDC and prohibited for a period of two years following termination of employment from soliciting PDC’s employees and customers.

Quantification

See the section entitled “—Quantification of Payments and Benefits to PDC’s Named Executive Officers” below for the estimated severance amounts for each named executive officer. Based on the assumptions described above under “—Certain Assumptions,” the estimated cash severance that would be payable to Ms. Jacoby is $1,106,250.

Integration Awards

In connection with the merger, PDC and Chevron have mutually agreed to establish an integration award bonus pool of up to $10,000,000 (subject to increase or decrease by mutual agreement of PDC and Chevron), for

58

which all PDC employees, including the PDC executive officers, are eligible. As of the date of this proxy statement/prospectus, the participants and the amounts each participant will be eligible to receive under the integration award bonus pool have yet to be determined. Any integration awards will vest in full and be paid on the closing date of the merger.

Indemnification Insurance

The merger agreement provides that the executive officers and non-employee directors of PDC and its subsidiaries will have the right to indemnification and continued coverage under directors’ and officers’ liability insurance policies for at least six years following the effective time of the merger. This indemnification and insurance coverage is further described in the section entitled “The Merger Agreement—Indemnification and Insurance of PDC Directors and Officers.”

New Compensation Arrangements with Chevron

Any PDC executive officers and directors who become officers, directors or employees of Chevron or who otherwise are retained by Chevron to provide services may enter into new individualized compensation arrangements effective as of the effective time of the merger and may participate following the effective time of the merger in cash or equity incentive or other benefit plans maintained by Chevron, any of its affiliates or PDC. As of the date of this proxy statement/prospectus, no compensation arrangements between such persons and Chevron and/or its affiliates have been established or discussed.

2023 Annual Bonus Payment

PDC and Chevron have agreed that if the effective time of the merger occurs prior to the date on which 2023 annual bonuses are paid to PDC employees in the ordinary course, then, at the effective time of the merger, each PDC employee, including each PDC executive officer, will receive an annual bonus payment in respect of fiscal year 2023 calculated based on actual performance. If the effective time of the merger occurs on or prior to September 30, 2023, this bonus payment will be pro-rated for the portion of 2023 that has elapsed prior to the effective time of the merger. For Messrs. Brookman, Meyers, and Lillo and Mses. Martinet and Jacoby, this 2023 annual bonus payment will be provided without duplication of any prorated annual bonus to which such executive officer would be entitled pursuant to the Severance Plan upon a qualifying termination of employment that occurs in 2023.

See the section entitled “—Quantification of Payments and Benefits to PDC’s Named Executive Officers” below for the estimated amount of the prorated 2023 annual bonus that each of PDC’s named executive officers would receive. Based on the assumptions described above under “—Certain Assumptions,” and assuming solely for purposes of this disclosure that the actual level of performance is equal to 100% of the target level, the estimated prorated 2023 annual bonus payment that would be paid to Ms. Jacoby is $73,750.

Quantification of Payments and Benefits to PDC’s Named Executive Officers

The information set forth below regarding the compensation of each of PDC’s named executive officers that is based on or otherwise relates to the merger is provided in accordance with Item 402(t) of Regulation S-K.

Except as otherwise specifically noted, the disclosure below uses the following assumptions:

59

The amounts indicated below are estimates based on multiple assumptions (including the assumptions described above) that may or may not actually occur or be accurate on the relevant date, and do not reflect certain compensation actions that may occur before completion of the transaction. Accordingly, the actual amounts received by our named executive officers may differ from the estimates set forth below.

Share Ownership of Directors, Executive Officers and Certain Beneficial Owners of PDC

PDC’s Directors and Executive Officers

The following table sets forth the number of shares and percentage of PDC common stock beneficially owned by PDC’s named executive officers, each of its directors, and all of its executive officers and directors as a group as of June 13, 2023, the most recent practicable date for which such information was available. Except as otherwise indicated, the address for each of the named security holders is c/o PDC Energy, Inc., 1099 18th Street, Suite 1500, Denver, CO 80202. None of the securities beneficially owned as set forth below is pledged as security.

62

Certain Beneficial Owners of PDC Common Stock

The following table shows certain information regarding the beneficial ownership of PDC common stock as of June 13, 2023, the most recent practicable date for which such information was available, by each person who is known by PDC to beneficially own more than five percent of the outstanding PDC common stock.

Director and Officer Indemnification

Under the merger agreement, certain indemnification and insurance rights exist in favor of PDC and its subsidiaries’ current and former directors and officers. For more information about these rights, see “The Merger—Interests of Directors and Executive Officers of PDC in the Merger—Indemnification and Insurance” beginning on page [    ].

63

Accounting Treatment of the Merger

In accordance with current accounting guidance, the merger will be accounted for using the acquisition method. As a result, the recorded assets and liabilities of Chevron will be carried forward at their recorded amounts, the historical operating results will be unchanged for the prior periods being reported on and the assets and liabilities of PDC will be adjusted to their respective estimated fair values at the closing date of the merger. In addition, all identified intangible assets will be recorded at estimated fair value and included as part of the net assets acquired. Any excess of the purchase price, consisting of the number of shares of Chevron common stock to be issued to former PDC stockholders, option holders and holders of restricted stock units awards, performance share awards or restricted stock awards, as applicable, at fair value, over the fair value of the net assets acquired including identified intangible assets of PDC on the closing date of the merger will be accounted for as goodwill. In accordance with current accounting guidance, goodwill will not be amortized but will be evaluated for impairment annually. Identified finite life intangible assets will be amortized over their estimated lives. Further, the acquisition method of accounting will result in the operating results of PDC being included in the operating results of Chevron beginning from the closing date of the merger.

Regulatory Approvals Required for the Merger

Chevron and PDC are not currently aware of any other material governmental approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations or other confirmations that are required prior to the parties’ completion of the transaction other than those described below. If additional approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations are required to complete the transaction, Chevron and PDC intend to seek such approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations.

Chevron and PDC expect to complete the transaction by year-end 2023. Although Chevron and PDC believe that they will receive the required approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations to complete the transaction, neither can give any assurance as to the timing of these approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations as to Chevron’s and PDC’s ultimate ability to obtain such approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations and other confirmations (or any additional approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations or other confirmations which may otherwise become necessary) or that such approvals, consents, registrations, permits, expirations or terminations of waiting periods, authorizations or other confirmations will be obtained on terms and subject to conditions satisfactory to Chevron and PDC. The receipt of the regulatory approvals (as described hereinafter) is a condition to the obligation of each of Chevron and PDC to complete the merger.

The merger is subject to the requirements of the HSR Act and the related rules and regulations, which provide that certain transactions may not be completed until notification and report forms have been furnished to the DOJ and the FTC and until certain waiting periods have been terminated or have expired. The HSR Act requires Chevron and PDC to observe a 30-calendar-day waiting period after the submission of their respective HSR notification and report forms before consummating their transaction. The waiting period may be shortened if the reviewing agency grants “early termination” of the waiting period (although the practice of granting early termination has been temporarily suspended by the FTC and DOJ), or lengthened if the acquiring person (here Chevron) voluntarily withdraws and refiles to allow a second 30-calendar-day waiting period, or if the reviewing agency issues a request for additional information or documentary material (a “Second Request”) prior to the expiration of the initial waiting period, the parties must observe a second 30-calendar-day waiting period, which begins to run only after each of the parties has substantially complied with the Second Request. It is also possible that Chevron and PDC could enter into a timing agreement with the FTC or DOJ that could affect the timing of the consummation of the merger.

64

On June 5, 2023, Chevron and PDC each filed a notification and report form under the HSR Act with the DOJ and the FTC, which filings started the initial 30-calendar-day waiting period under the HSR Act.

Treatment of Existing Debt

In connection with the merger, Chevron currently expects to repay in full or otherwise acquire PDC’s outstanding 6.125% Senior Note due 2024 and 5.75% Senior Notes due 2026. In connection with the merger, Chevron expects to terminate PDC’s $3.5 billion revolving credit facility, under which $352 million was outstanding as of March 31, 2023. Chevron also expects to retain PDC’s existing lease obligations following the merger.

Treatment of PDC Equity Awards

PDC SARs. At the effective time of the merger, each outstanding PDC SAR, whether or not vested, will be converted into a Chevron SAR, on the same terms and conditions as were applicable under such PDC SAR immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded down to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC SAR immediately prior to the effective time of the merger by (ii) the exchange ratio. The exercise price per share of Chevron common stock subject to any such Chevron SAR at and after the effective time of the merger will be an amount (rounded up to the nearest one hundredth of a cent) equal to (i) the exercise price per share of PDC common stock subject to such PDC SAR immediately prior to the effective time of the merger divided by (ii) the exchange ratio.

PDC RSU Awards. At the effective time of the merger, each outstanding PDC RSU award, whether or not vested, will be converted into a Chevron RSU award, on the same terms and conditions as were applicable under such PDC RSU award immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares PDC common stock subject to such PDC RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

PDC PSU Awards. At the effective time of the merger, each outstanding PDC PSU award, whether or not vested, will be treated as follows:

65

PDC Director RSU Awards. At the effective time of the merger, each outstanding PDC Director RSU award, whether or not vested, will be converted into the right to receive, within five business days of the completion of the merger, the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC Director RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

Any amounts relating to dividend equivalent rights granted with respect to the foregoing PDC equity awards that are accrued but unpaid as of the completion of the merger will carry over and will be paid if required by and in accordance with the terms and conditions as were applicable to such equity award immediately prior to the completion of the merger (or, in the case of PDC PSU awards granted in 2021 and PDC Director RSU awards, will be paid within five business days of the completion of the merger).

For additional information on PDC’s equity awards, see “The Merger—Interests of Directors and Executive Officers of PDC in the Merger” beginning on page [    ].

No Appraisal Rights

PDC stockholders are not entitled to appraisal rights in connection with the merger.

Appraisal rights are statutory rights that enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the transaction.

Holders of shares of PDC common stock will not have rights to an appraisal of the fair value of their shares. Under the DGCL, appraisal rights are not available for the shares of any class or series if the shares of the class or series are listed on a national securities exchange or held of record by more than 2,000 holders on the record date, unless the stockholders are required to receive in exchange for their shares anything other than shares of stock of the surviving or resulting corporation, shares of stock or depository receipts in respect thereof of any other corporation that will be either listed on a national securities exchange or held of record by more than 2,000 holders at the effective time of the merger, cash in lieu of fractional shares or fractional depositary receipts or any combination of the foregoing. Shares of PDC common stock are listed on Nasdaq as of the record date, and PDC stockholders will receive Chevron common stock pursuant to the merger agreement and cash in lieu of fractional shares. Approval for the listing of the shares of Chevron common stock on the NYSE is a condition to completion of the merger.

NYSE Listing of Chevron Common Stock; Delisting and Deregistration of PDC Common Stock

Prior to the completion of the merger, Chevron has agreed to take all necessary action to cause the shares of Chevron common stock to be issued in connection with the merger to be approved for listing on the NYSE subject to official notice of issuance. The listing on the NYSE of the shares of Chevron common stock to be issued in connection with the merger is also a condition to completion of the merger.

Prior to the effective time of the merger, PDC will cooperate with Chevron and use its reasonable best efforts to take, or cause to be taken, all actions and do, or cause to be done, all things reasonably necessary,

66

proper or advisable on its part pursuant to applicable law and the rules and regulations of the NYSE or Nasdaq to cause (a) the delisting of PDC common stock from Nasdaq as promptly as practicable after the effective time of the merger and (b) the deregistration of PDC common stock pursuant to the Exchange Act as promptly as practicable after such delisting. If the merger is completed, PDC common stock will cease to be listed on Nasdaq and PDC common stock will be deregistered under the Exchange Act, after which PDC will no longer be required under SEC rules and regulations to file periodic reports with the SEC in respect of PDC common stock.

Material U.S. Federal Income Tax Consequences

The following is a general discussion of the material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of PDC common stock that exchange their PDC common stock for Chevron common stock in the merger.

This discussion is based upon the Code, its legislative history, U.S. Treasury regulations promulgated under the Code and judicial and administrative rulings and decisions, all as in effect on the date of this proxy statement/prospectus. These authorities may change, possibly retroactively, or be subject to differing interpretations, and any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth in this discussion.

This discussion addresses only those U.S. holders (as defined below) of PDC common stock that hold their PDC common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion is not a complete description of all of the U.S. federal income tax consequences of the merger and, in particular, does not address any tax consequences arising under the Medicare contribution tax on net investment income or the Foreign Account Tax Compliance Act of 2010 (including the U.S. Treasury regulations promulgated thereunder and intergovernmental agreements entered into pursuant thereto or in connection therewith), nor does it address any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax (such as estate or gift tax laws). Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to you in light of your individual circumstances or that may be applicable to you if you are subject to special treatment under the U.S. federal income tax laws, including if you are:

67

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of shares of PDC common stock that is, for U.S. federal income tax purposes, (1) an individual who is a citizen or resident of the United States, (2) a corporation created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes, or (4) an estate the income of which is subject to U.S. federal income taxation regardless of its source. Beneficial owners of PDC common stock that are not U.S. holders should consult their own tax advisors as to U.S. federal income tax consequences of the merger.

If an entity or an arrangement treated as a partnership for U.S. federal income tax purposes holds shares of PDC common stock, the U.S. federal income tax consequences to a partner in such partnership (or owner of such entity) generally will depend on the status of the partner (or member) and the activities of the partnership (or entity). Any entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds shares of PDC common stock, and any persons that, for U.S. federal income tax purposes, are treated as partners in such partnership, should consult their own tax advisors with respect to the tax consequences of the merger in their specific circumstances.

This discussion is not tax advice and does not purport to be a complete analysis or discussion of all U.S. federal income tax considerations relating to the merger. The tax consequences of the merger may be complex and will depend on your specific situation and factors not within Chevron’s or PDC’s control. You should consult your own tax advisor as to the tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any U.S. federal, U.S. state or local, non-U.S. or other tax laws and of changes in such laws.

In General

The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and Chevron and PDC intend to report the merger consistent with such qualification. In the merger agreement, each of Chevron and PDC represents that it has not taken or agreed to take any action, and is not aware, after reasonable diligence, of the existence of any fact or circumstance that could reasonably be expected to prevent or impede the merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, Chevron and PDC agree not to (and not to permit their subsidiaries to) take any action that would prevent or impede, or could reasonably be expected to prevent or impede, the merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code and to, and to cause their respective subsidiaries to, use its reasonable best efforts to cause the merger to so qualify. However, it is not a condition to PDC’s obligation or Chevron’s obligation to complete the transaction that the merger be treated as a “reorganization” or that Chevron or PDC receive an opinion from counsel to that effect and even if an opinion of counsel to that effect were obtained by either party, such opinion would not be binding on the IRS or any court. PDC and Chevron have not sought, and will not seek, any ruling from the IRS regarding any matters relating to the merger. As a result, there can be no assurance that the IRS would not assert that the merger fails to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, or that a court would not sustain such a position.

68

U.S. Federal Income Tax Consequences if the Merger Qualifies as a “Reorganization” Described in Section 368(a) of the Code

If the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, the material U.S. federal income tax consequences of the merger to U.S. holders generally will be as follows:

If a U.S. holder of PDC common stock acquired different blocks of PDC common stock at different times or at different prices, such U.S. holder’s basis and holding period in its shares of Chevron common stock may be determined separately with reference to each block of PDC common stock. Any such U.S. holder should consult its tax advisor regarding the determination of the tax basis and/or holding periods of the particular shares of Chevron common stock received in the merger.

A U.S. holder of PDC common stock who receives cash instead of a fractional share of Chevron common stock generally will be treated as having received such fractional share pursuant to the merger, and then as having sold such fractional share for cash. As a result, such U.S. holder generally will recognize gain or loss based on the difference, if any, between the amount of such cash received and the U.S. holder’s tax basis in such fractional share of Chevron common stock (determined as described above). Such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder’s holding period in the fractional share of Chevron common stock deemed to be received exceeds one year at the effective time of the merger. The deductibility of capital losses is subject to limitation.

Tax Consequences if the Merger Does Not Qualify as a “Reorganization” Described in Section 368(a) of the Code

If the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes, then a U.S. holder of shares of PDC common stock that exchanges such shares of PDC common stock for Chevron common stock generally will recognize gain or loss equal to the difference, if any, between (i) the sum of the fair market value of the shares of Chevron common stock actually received by such U.S. holder and the amount of any cash received in lieu of a fractional share of Chevron common stock and (ii) such U.S. holder’s adjusted tax basis in the PDC common stock exchanged therefor. Gain or loss must be calculated separately for each block of PDC common stock exchanged by such U.S. holder if such blocks were acquired at different times or for different prices. Such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder’s holding period in a particular block of PDC common stock exceeds one year at the effective time of the merger. A U.S. holder’s aggregate tax basis in the Chevron common stock received in the merger will equal the fair market value of such shares of Chevron common stock as of the effective time of the merger, and the holding period of such Chevron common stock will begin on the date after the merger.

69

Backup Withholding

Payments of cash to U.S. holders in lieu of a fractional share of Chevron common stock in connection with the merger generally will be subject to information reporting and may be subject to backup withholding (currently at a rate of 24%). To prevent backup withholding, U.S. holders should:

Any amounts withheld under the backup withholding rules are not an additional tax and will generally be allowed as a refund or credit against a U.S. holder’s U.S. federal income tax liability, if any, provided that such U.S. holder timely furnishes the required information to the IRS.

The preceding discussion is intended only as a summary of the material U.S. federal income tax consequences of the merger and is not tax advice. It is not a complete analysis or discussion of all potential tax considerations that may be important to a holder of PDC common stock. Holders of PDC common stock should consult their own tax advisors with respect to the tax consequences of the merger in their particular circumstances, including the applicability and effect of the alternative minimum tax and any U.S. federal, U.S. state or local, non-U.S. or other tax laws and of changes in such laws.

Restrictions on Sales of Shares of Chevron Common Stock Received in the Merger

All shares of Chevron common stock received by PDC stockholders in the merger will be freely tradable for purposes of the Securities Act of 1933, as amended (the “Securities Act”) and the Exchange Act except for shares of Chevron common stock received by any PDC stockholder who becomes an “affiliate” of Chevron after completion of the merger. This proxy statement/prospectus does not cover resales of shares of Chevron common stock received by any person upon completion of the merger, and no person is authorized to make any use of this proxy statement/prospectus in connection with any resale.

Certain Contracts between Chevron and PDC

Chevron and PDC are party to commercial arrangements with one another, which are not material, individually or in the aggregate to either company.

THE MERGER AGREEMENT

Explanatory Note Regarding the Merger Agreement

This section of this proxy statement/prospectus describes the material provisions of the merger agreement, but does not describe all of the terms of the merger agreement and may not contain all of the information about the merger agreement that is important to you. The following summary is qualified by reference to the complete text of the merger agreement, which is attached as Annex A to this proxy statement/prospectus and incorporated by reference herein. The rights and obligations of Chevron, PDC and Merger Subsidiary, are governed by the express terms and conditions of the merger agreement and not by this summary or any of the other information contained in this proxy statement/prospectus. You are urged to read the full text of the merger agreement because it is the legal document that governs the merger.

The merger agreement contains representations, warranties and covenants by each of the parties to the agreement, which were made only for purposes of the agreement, as of specified dates. The representations, warranties and covenants in the merger agreement were made solely for the benefit of the parties to the merger agreement; may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the merger agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Chevron, Merger Subsidiary, PDC or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants contained in the merger agreement or any other agreement between such parties may change after the date of each such agreement, which subsequent information may or may not be fully reflected in Chevron’s or PDC’s public disclosures or the public disclosures of any of their respective subsidiaries or affiliates. Each such agreement should not be read alone, but should instead be read in conjunction with the other information regarding the respective agreement, the merger, Chevron, PDC and their respective affiliates and businesses, which is contained in, or incorporated by reference into, this proxy statement/prospectus, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and other filings that each of Chevron and PDC has made or will make with the SEC. See “Where You Can Find More Information” beginning on page [    ].

Structure of the Merger

The merger agreement provides, upon the terms and subject to the conditions set forth therein and in accordance with the DGCL, for Merger Subsidiary to merge with and into PDC, with PDC continuing as the surviving corporation and a direct, wholly-owned subsidiary of Chevron. As used herein, surviving corporation means PDC following the merger.

At the effective time of the merger, by virtue of the merger, the certificate of incorporation of PDC will be amended and restated in its entirety as set forth in Exhibit A to the merger agreement, and as so amended and restated, will be the certificate of incorporation of the surviving corporation. At the effective time of the merger, the by-laws of PDC will be amended and restated in its entirety as set forth in the by-laws of Merger Subsidiary, as in effect immediately prior to the effective time of the merger, except that all references therein to Merger Subsidiary will be automatically amended and will become references to PDC, and as so amended and restated, will be the by-laws of the surviving corporation. The directors of Merger Subsidiary immediately prior to the effective time of the merger will be the initial directors of the surviving corporation, each to hold office in accordance with the certificate of incorporation and the by-laws of the surviving corporation, and the officers of Merger Subsidiary immediately prior to the effective time of the merger will be the initial officers of the surviving corporation, in each case until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal. As used herein, the “effective time” of the merger means the time

at which the certificate of merger with respect to the merger is duly filed with the Secretary of State of the State of Delaware or at such later time as Chevron and PDC may agree and specify in such certificate of merger.

Timing of Closing

Unless another place and time is agreed to in writing by Chevron and PDC, or if Chevron elects to defer the closing of the merger in certain circumstances where the closing of the merger would otherwise take place near the end of the month (in which case the closing of the merger will occur at the time described below), the closing of the merger will occur no later than the second business day following the day on which the last of the conditions (other than those conditions that by their nature are to be fulfilled at the closing, but subject to the waiver or fulfillment of such conditions) set forth in the merger agreement has been fulfilled or waived, but no later than the end date (as defined below under the heading “—Termination of the Merger Agreement”) (the “initial closing date”). The date on which the closing of the merger occurs is referred to as the “closing date” in this proxy statement/prospectus.

If, but for this paragraph, the closing of the merger would occur on any date which is ten or fewer calendar days prior to the last calendar day of any calendar month (a “specified month end date”), then, if elected in writing by Chevron prior to the initial closing date, (i) the closing date will take place on the first business day following the latest specified month end date or (ii) if the closing of the merger cannot take place on such date as a result of failure of the condition requiring the absence of any provision of any applicable law or regulation, and of any judgment, injunction, order or decree, that prohibits or enjoins the completion of the merger, the next business day on which such failure no longer exists. The date on which the closing of the merger will occur pursuant to clause (i) or (ii) of the immediately preceding sentence is referred to as the “deferred closing date” in this proxy statement/prospectus. Any election to so defer the closing of the merger must include Chevron’s confirmation that (i) at the time of such election, all of the parties’ mutual conditions and all of Chevron’s conditions to complete the merger were satisfied on the date the closing of the merger would have occurred but for Chevron’s deferral election and (ii) all such conditions (other than (A) the condition requiring the absence of any provision of any applicable law or regulation, and of any judgment, injunction, order or decree, that prohibits or enjoins the completion of the merger and (B) the condition requiring that PDC has performed in all material respects of all of its obligations of PDC in the merger agreement required to be performed by it prior to the closing date (but only to the extent PDC’s material and intentional breach after its receipt of Chevron’s deferral election was a principal cause of the failure of such condition to be satisfied)) will be deemed to be satisfied as of the deferred closing date. Nothing in this paragraph or otherwise affects the need for PDC’s conditions to complete the merger to be fulfilled or waived, as applicable, at the deferred closing date.

Merger Consideration

Conversion of Shares

At the effective time of the merger, each outstanding share of PDC common stock (other than the cancelled shares (as defined below) and certain shares of PDC common stock subject to PDC equity awards that will be treated in the manner described below under the heading “—Treatment of PDC Equity Awards”) will automatically be cancelled and retired and will cease to exist and each holder thereof will thereafter have no rights with respect to such securities except the right to receive:

72

Shares of PDC common stock owned by PDC, Chevron or Merger Subsidiary will be cancelled in the merger without payment of any consideration, as described below under the heading “—Cancelled Shares.”

Chevron will make available to the exchange agent, as needed, the merger consideration to be delivered in respect of certificates and book-entry shares formerly representing shares of PDC common stock.

Cancelled Shares

At the effective time of the merger, all shares of PDC common stock that are owned directly by Chevron, Merger Subsidiary or PDC will be cancelled and retired and will cease to exist and no stock of Chevron, cash or other consideration will be delivered in exchange therefor. Such shares are referred to as “cancelled shares” in this proxy statement/prospectus. For the avoidance of doubt, the foregoing two sentences will not apply to shares of PDC common stock held in trust or otherwise set aside from shares held in PDC’s treasury pursuant to any PDC benefit plan.

Treatment of Fractional Shares

PDC stockholders will not receive any fractional shares of Chevron common stock pursuant to the merger. Each holder of PDC common stock that otherwise would have been entitled to receive a fractional share of Chevron common stock at the effective time of the merger will receive an amount in cash, without interest, rounded to the nearest cent, in lieu of such fractional share. The value of such cash payment will be calculated by the exchange agent and will represent the holder’s proportionate interest in a trust of proceeds established from the open-market sale of that number of shares of Chevron common stock equal to the excess of (i) the aggregate number of shares of Chevron common stock delivered to the exchange agent by Chevron pursuant to the terms of the merger agreement over (ii) the aggregate number of whole shares of Chevron common stock to be distributed to PDC stockholders pursuant to the terms of the merger agreement.

Exchange of PDC Stock Certificates and Book-Entry Shares

Prior to the effective time of the merger, Chevron will appoint a bank, trust company or nationally recognized stockholder services provider or other person reasonably acceptable to PDC as the exchange agent for the purpose of exchanging certificates and book-entry shares representing shares of PDC common stock with shares of Chevron common stock. Promptly after the effective time of the merger, Chevron will send, or will cause the exchange agent to send, to each holder of record of PDC common stock converted into the right to receive the merger consideration, a letter of transmittal for use in the exchange and instructions explaining how to surrender PDC shares to the exchange agent.

Holders of PDC common stock who surrender certificates or book-entry shares that formerly represented outstanding shares of PDC common stock to the exchange agent, together with a properly completed letter of transmittal, will be entitled to receive (i) the merger consideration and (ii) a check in the amount equal to any cash payable (x) in lieu of fractional shares which such holder has the right to receive pursuant to the terms of the merger agreement, and (y) in respect of any dividends and other distributions which such holder has the right to receive pursuant to the terms of the merger agreement. PDC stockholders should not return stock certificates with

73

the enclosed proxy card. Exchange of any book-entry shares of PDC common stock will be effected in accordance with Chevron’s customary procedures with respect to securities represented by book entry. Until so surrendered, certificates and book-entry shares will, after the effective time of the merger, represent for all purposes only the right to receive the merger consideration. No interest will be paid or will accrue for the benefit of holders of the certificates or book-entry shares that formerly represented outstanding shares of PDC common stock on the merger consideration payable pursuant to the merger agreement, any cash in lieu of fractional shares or any unpaid dividends and distributions payable pursuant to the merger agreement to such holders of certificates or book-entry shares that formerly represented outstanding shares of PDC common stock.

Withholding

Each of Chevron, PDC, Merger Subsidiary, the surviving corporation and the exchange agent will be entitled to deduct and withhold from the consideration otherwise payable to any person pursuant to the merger agreement such amounts as are required to be deducted or withheld with respect to the making of such payment under any provision of federal, state, local or foreign tax law (and to the extent deduction and withholding is required, such deduction and withholding may be taken in Chevron common stock). To the extent that amounts are so deducted or withheld by Chevron, PDC, Merger Subsidiary, the surviving corporation or the exchange agent and paid over to the applicable taxing authority in accordance with applicable law, such deducted or withheld amounts will be treated for all purposes of the merger agreement as having been paid to the person in respect of which such deduction or withholding was made and, if withholding is taken in Chevron common stock, the relevant withholding party will be treated as having sold such Chevron common stock on behalf of such person for an amount of cash equal to the fair market value thereof at the time of such deemed sale and paid such cash proceeds to the appropriate taxing authority.

Lost Certificates

If a certificate representing shares of PDC common stock has been lost, stolen or destroyed, then, before a PDC stockholder will be entitled to receive the merger consideration to be paid in respect of the shares of PDC common stock represented by such lost, stolen or destroyed certificate, the holder will need to deliver an affidavit of that fact and, if required by Chevron or the surviving corporation, post a bond, in such reasonable amount as the surviving corporation may direct, as indemnity against any claim that may be made against it with respect to such certificate in addition to such holder providing a properly completed and duly executed letter of transmittal.

Potential Adjustment to Merger Consideration

In the event that, before the completion of the merger, any change in the outstanding shares of capital stock of Chevron or PDC occurs as a result of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, the merger consideration, the exchange ratio and any other similarly dependent item, as the case may be, will be appropriately adjusted in order to provide PDC stockholders with the same economic effect contemplated by the merger agreement prior to such event. No such adjustment will be made for cash dividends or grants of equity compensation not prohibited by the merger agreement.

Treatment of PDC Equity Awards

PDC SARs. At the effective time of the merger, each outstanding PDC SAR, whether or not vested, will be converted into a Chevron SAR, on the same terms and conditions as were applicable under such PDC SAR immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded down to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC SAR immediately prior to the completion of the merger by (ii) the exchange ratio. The exercise price per share of Chevron common stock subject to any such Chevron SAR at and after the effective time of the merger will be an amount (rounded up to

74

the nearest one hundredth of a cent) equal to (i) the exercise price per share of PDC common stock subject to such PDC SAR immediately prior to the effective time of the merger divided by (ii) the exchange ratio.

PDC RSU Awards. At the effective time of the merger, each outstanding PDC RSU award, whether or not vested, will be converted into a Chevron RSU award, on the same terms and conditions as were applicable under such PDC RSU award immediately prior to the effective time of the merger (including any provisions for acceleration), with respect to the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares PDC common stock subject to such PDC RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

PDC PSU Awards. At the effective time of the merger, each outstanding PDC PSU award, whether or not vested, will be treated as follows:

PDC Director RSU Awards. At the effective time of the merger, each outstanding PDC Director RSU award, whether or not vested, will be converted into the right to receive, within five (5) business days of the completion of the merger, the number (rounded to the nearest whole number) of shares of Chevron common stock determined by multiplying (i) the number of shares of PDC common stock subject to such PDC Director RSU award immediately prior to the effective time of the merger by (ii) the exchange ratio.

Any amounts relating to dividend equivalent rights granted with respect to the foregoing PDC equity awards that are accrued but unpaid as of the completion of the merger will carry over and will be paid if required by and in accordance with the terms and conditions as were applicable to such equity award immediately prior to the completion of the merger (or, in the case of PDC PSU awards granted in 2021 and PDC Director RSU awards, will be paid within five (5) business days of the completion of the merger).

Covenants and Agreements

Conduct of Business

Each of Chevron and PDC has agreed to certain covenants in the merger agreement restricting the conduct of its respective business between May 21, 2023 and the earlier of the completion of the merger and the termination of the merger agreement.

Interim Operations of PDC. The merger agreement provides that until the effective time of the merger, except with the prior written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed), PDC and its subsidiaries will use all reasonable best efforts to conduct their business in the ordinary course consistent of business with past practice, provided, that PDC and its subsidiaries may take commercially reasonable (taking into account the reasonableness perspective of each of Chevron and PDC) actions outside of the ordinary course or not consistent with past practice in response to external unforeseen events, changes or developments of the following type in a manner consistent with those generally undertaken by businesses similarly situated to PDC:

PDC has also agreed that during this period it and its subsidiaries will (i) use all reasonable best efforts to conduct their business in a manner not involving entry into businesses that are materially different from the businesses of PDC and its subsidiaries on the date of the merger agreement and (ii) use their commercially reasonable efforts to preserve intact their business organizations and material relationships with third parties.

In addition, PDC has agreed that during this period, except with the prior written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed), it will not, and will not permit any of its subsidiaries to:

76

77

78

The obligations of PDC and its subsidiaries described above will not apply to the marketing and sale of hydrocarbons in the ordinary course of business consistent with past practice.

Interim Operations of Chevron. The merger agreement provides that until the effective time of the merger, except with the prior written consent of PDC (such consent not to be unreasonably withheld, conditioned or delayed), Chevron and its subsidiaries will conduct their business in a manner not involving the entry by Chevron or its subsidiaries into lines of business that are materially different from the lines of business of Chevron and its subsidiaries as of the date of the merger agreement. In addition, Chevron has agreed that during this period, except with the prior written consent of PDC (such consent not to be unreasonably withheld, conditioned or delayed), it will not, and will not permit any of its subsidiaries to:

79

PDC Stockholder Meeting. The merger agreement requires PDC, within 40 days from the Form S-4 clearance date (as defined below) (or, if PDC’s nationally recognized proxy solicitation firm advises 40 days from the Form S-4 clearance date is insufficient time to submit and obtain the PDC stockholder approval, such later date to which Chevron consents (such consent not to be unreasonably withheld, conditioned or delayed)), to duly call, give notice of, convene and hold a meeting of its stockholders (the “PDC stockholder meeting”), for the purpose of obtaining the PDC stockholder approval. The term “Form S-4 clearance date” refers to the date that is the earlier to occur of either (i) (A) the date that is ten days after the filing of Chevron’s registration statement on Form S-4, of which this proxy statement/prospectus forms a part, if the SEC does not indicate it will be providing comments or (B) such earlier date as Chevron or PDC receives confirmation that the SEC will not provide comments or indicates that it does not plan to provide comments to the filing of such registration statement, or (ii) the date the SEC confirms that it has no further comments on such registration statement.

Without the prior written consent of Chevron, matters contemplated by the PDC stockholder approval are the only matters (other than matters of procedure and matters required by law to be voted on by PDC’s stockholders in connection therewith) that PDC may propose to be voted on by the PDC stockholders at the PDC stockholder meeting.

PDC may not adjourn, postpone or otherwise delay the PDC stockholder meeting without the prior written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed) unless (i) after consultation with Chevron, PDC believes in good faith that such adjournment or postponement is reasonably necessary to allow reasonable additional time to (A) solicit additional proxies necessary to obtain the PDC stockholder approval, or (B) distribute any supplement or amendment to the PDC proxy statement the distribution of which the PDC Board has determined in good faith to be necessary under applicable law after consultation with, and taking into account the advice of, outside legal counsel or (ii) for an absence of a quorum, in which case PDC will use its reasonable best efforts to obtain such a quorum as promptly as practicable. Notwithstanding the foregoing, (1) PDC may not, without the prior written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed), postpone the PDC stockholder meeting more than a total of three times pursuant to clause (i)(A) or (ii) of the immediately preceding sentence, and no such postponement or adjournment pursuant to clause (i)(A) or (ii) of the immediately preceding sentence will be, without the prior written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed), for a period exceeding ten business days and in no event may PDC postpone the PDC stockholder meeting without the written consent of Chevron (such consent not to be unreasonably withheld, conditioned or delayed) if doing so would require the setting of a new record date, and (2) if the PDC stockholder meeting is postponed, PDC will reconvene the PDC stockholder meeting at the earliest practicable date on which the PDC Board reasonably expects to have sufficient affirmative votes to obtain the PDC stockholder approval. PDC will otherwise coordinate and cooperate with Chevron with respect to the timing of the PDC stockholder meeting and will otherwise comply with all legal requirements applicable to the PDC stockholder meeting. PDC will provide updates to Chevron with respect to the proxy solicitation for the PDC stockholders meeting (including interim results) as reasonably requested by Chevron.

No Solicitation. PDC has agreed that it and its subsidiaries will not, and that it will direct and use its reasonable best efforts to cause its and its subsidiaries’ respective officers, directors, employees, investment bankers, consultants, attorneys, accountants, agents and other representatives not to, directly or indirectly:
