MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

Dear Stockholders:

Marathon Oil Corporation (which we refer to as “Marathon Oil”) has entered into a merger agreement (which, as it may be amended from time to time, we refer to as the “merger agreement”) with Puma Merger Sub Corp. (which we refer to as “Merger Sub”) and ConocoPhillips, pursuant to which Merger Sub will merge with and into Marathon Oil, with Marathon Oil surviving as a wholly owned subsidiary of ConocoPhillips (which we refer to as the “merger”).

Marathon Oil stockholders as of the close of business on July 26, 2024, the record date, are invited to attend a special meeting of Marathon Oil stockholders on August 29, 2024, at 8:00 a.m., Central Time, in the Level 6 Auditorium of One MRO, located at 990 Town & Country Blvd in Houston, Texas 77024, to consider and vote upon (i) a proposal to adopt the merger agreement, (ii) a non-binding advisory proposal to approve certain compensation that may be paid or become payable to Marathon Oil’s named executive officers that is based on or otherwise relates to the merger and (iii) a proposal to adjourn the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes cast at the special meeting to approve the proposal to adopt the merger agreement.

If the merger is completed, Marathon Oil stockholders will be entitled to receive, without interest, 0.255 shares of ConocoPhillips common stock for each issued and outstanding share of Marathon Oil stock they had held immediately prior to the effective time of the merger (which we refer to as the “merger consideration”) as further described in the proxy statement/prospectus accompanying this notice. The market value of the merger consideration will fluctuate with the price of ConocoPhillips common stock. Based on the closing price of ConocoPhillips common stock on May 28, 2024, the last trading day before the public announcement of the signing of the merger agreement, the value of the per share merger consideration payable to holders of Marathon Oil common stock upon completion of the merger was approximately $30.33. Based on the closing price of ConocoPhillips common stock on July 26, 2024, the last practicable date before the date of the proxy statement/prospectus accompanying this notice, the value of the merger consideration payable to holders of Marathon common stock upon completion of the merger was approximately $28.27. Marathon Oil stockholders should obtain current stock price quotations for ConocoPhillips common stock and Marathon Oil common stock. ConocoPhillips common stock is traded on the New York Stock Exchange under the symbol “COP,” and Marathon Oil common stock is traded on the New York Stock Exchange under the symbol “MRO.”

The Marathon Oil board of directors has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to, and in the best interests of, Marathon Oil stockholders; has unanimously approved and declared advisable the merger agreement and the transactions contemplated by the merger agreement, including the merger; and unanimously recommends that Marathon Oil stockholders vote “FOR” the adoption of the merger agreement and “FOR” the other proposals described in the accompanying proxy statement/prospectus.

Marathon Oil will hold an in person special meeting of its stockholders to consider certain matters relating to the merger. The merger cannot be completed unless, among other things, Marathon Oil stockholders adopt the merger agreement.

Your vote is very important. To ensure your representation at the special meeting, complete and return the enclosed proxy card or submit your proxy by phone or the Internet. Please vote promptly whether or not you expect to attend the special meeting. Submitting a proxy now will not prevent you from being able to vote at the special meeting.

The proxy statement/prospectus for the special meeting, which both summarizes the merger agreement and attaches a copy thereto, is attached to this notice, and incorporated by reference into this notice.

The proxy statement/prospectus accompanying this notice is also being delivered to Marathon Oil’s stockholders as ConocoPhillips’ prospectus for its offering of shares of ConocoPhillips common stock in connection with the merger.

The obligations of ConocoPhillips and Marathon Oil to complete the merger are subject to the satisfaction or waiver of the conditions set forth in the merger agreement, a copy of which is included as part of the accompanying proxy statement/prospectus. The proxy statement/prospectus provides you with detailed information about the merger. It also contains or references information about ConocoPhillips and Marathon Oil and certain related matters. You are encouraged to read the proxy statement/prospectus carefully and in its entirety. In particular, you should carefully read the section entitled “Risk Factors” beginning on page 26 of the proxy statement/prospectus for a discussion of risks you should consider in evaluating the merger and the issuance of shares of ConocoPhillips common stock in connection with the merger and how they will affect you.

stock entitled to vote on the proposal. Marathon Oil stockholders are requested to complete, date, sign and return the enclosed proxy in the envelope provided, which requires no postage if mailed in the United States, or to submit their votes by phone or the Internet. Simply follow the instructions provided on the enclosed proxy card. Abstentions, failure to submit a proxy or vote at the special meeting and broker non-votes will have the same effect as a vote “AGAINST” the merger proposal.

BY ORDER OF THE BOARD OF DIRECTORS,

Kim Warnica

Executive Vice President, General Counsel and Secretary

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following are answers to certain questions that you may have regarding the merger and the special meeting. You are urged to read the remainder of this document carefully because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the annexes to, and the documents incorporated by reference in, this document.

Q:

Why am I receiving this proxy statement/prospectus?

A:

You are receiving this proxy statement/prospectus because ConocoPhillips, Marathon Oil and Merger Sub have entered into the merger agreement, pursuant to which, on the terms and subject to the conditions included in the merger agreement, ConocoPhillips has agreed to acquire Marathon Oil by means of a merger of Merger Sub with and into Marathon Oil (which we refer to as the “merger”), with Marathon Oil surviving the merger as a wholly owned subsidiary of ConocoPhillips, and your vote is required in connection with the merger. The merger agreement, which governs the terms of the merger, is attached to this proxy statement/prospectus as Annex A.

The merger agreement must be adopted by the Marathon Oil stockholders in accordance with the General Corporation Law of the State of Delaware (which we refer to as the “DGCL”) in order for the merger to be consummated. Marathon Oil is holding a special meeting of its stockholders (which we refer to as the “special meeting”) to obtain that approval. Marathon Oil stockholders will also be asked to vote on a non-binding advisory proposal to approve certain compensation that may be paid or become payable to Marathon Oil’s named executive officers that is based on or otherwise relates to the merger and to approve a proposal to adjourn the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes cast at the special meeting to approve the merger proposal. Your vote is very important. We encourage you to submit a proxy to have your shares of common stock, par value $1.00 per share, of Marathon Oil (which we refer to as “Marathon Oil common stock”) voted as soon as possible.

Q:

Who is entitled to vote at the special meeting?

A:

The Marathon Oil board has fixed July 26, 2024 as the record date for the special meeting. All holders of record of shares of Marathon Oil common stock as of the close of business on the record date are entitled to receive notice of, and to vote at, the special meeting, provided that those shares remain outstanding on the date of the special meeting. As of the record date, there were 559,383,423 shares of Marathon Oil common stock issued and outstanding and entitled to vote at the special meeting. Attendance at the special meeting is not required to vote. Instructions on how to vote your shares without attending the special meeting are provided in this section below.

Q:

When and where will the special meeting take place?

A:

The special meeting will be held on August 29, 2024, at 8:00 a.m., Central Time, in the Level 6 Auditorium of One MRO, located at 990 Town & Country Blvd in Houston, Texas 77024. Even if you plan to attend the special meeting, Marathon Oil recommends that you vote your shares in advance as described above so that your vote will be counted if you later decide not to or become unable to attend the special meeting.

Q:

What are the protocols for attending the special meeting?

A:

Marathon Oil encourages its stockholders to arrive at the special meeting prior to the start time to leave ample time for check-in procedures. To be admitted to the special meeting, you must bring valid picture identification, such as a driver’s license or passport, and provide proof of stock ownership. If your shares are held in the name of a bank, broker, or other nominee, you must obtain a “legal proxy” from the bank, broker or other nominee that holds your shares in order to vote at the special meeting and present proof of your ownership of Marathon Oil common stock, such as a bank or brokerage account statement, indicating that you owned shares of Marathon Oil common stock at the close of business on the record date.

Q:

What matters will be considered at the special meeting?

A:

Marathon Oil stockholders are being asked to consider and vote on:

•

a proposal to adopt the merger agreement (which we refer to as the “merger proposal”);

•

a proposal to approve, by a non-binding advisory vote, certain compensation that may be paid or become payable to Marathon Oil’s named executive officers that is based on or otherwise relates to the merger (which we refer to as the “non-binding compensation advisory proposal”); and

•

a proposal to adjourn the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes cast at the special meeting to approve the merger proposal (which we refer to as the “adjournment proposal”).

Q:

Is my vote important?

A:

Yes. Your vote is very important. The merger cannot be completed unless the merger proposal is approved by the affirmative vote of a majority of the outstanding shares of Marathon Oil common stock entitled to vote on the proposal. Only Marathon Oil stockholders as of the close of business on the record date are entitled to vote at the special meeting. The board of directors of Marathon Oil (which we refer to as the “Marathon Oil board” or the “Marathon Oil board of directors”) unanimously recommends that such Marathon Oil stockholders vote “FOR” the approval of the merger proposal, “FOR” the approval of the non-binding compensation advisory proposal and “FOR” the adjournment proposal.

Q:

If my shares of Marathon Oil common stock are held in “street name” by my broker, bank or other nominee, will my broker, bank or other nominee automatically vote those shares for me?

A:

If your shares are held through a broker, bank or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” The “record holder” of such shares is your broker, bank or other nominee, and not you. If this is the case, this proxy statement/​prospectus has been forwarded to you by your broker, bank or other nominee. You must provide the record holder of your shares with instructions on how to vote your shares. Otherwise, your broker, bank or other nominee will not vote your shares on any of the proposals to be considered at the special meeting. A so called “broker non-vote” will result if your broker, bank or other nominee returns a proxy but does not provide instruction as to how shares should be voted on a particular matter.

Under the current rules of the NYSE, brokers, banks or other nominees do not have discretionary authority to vote on any of the proposals at the special meeting. Because the only proposals for consideration at the special meeting are non-discretionary proposals, it is not expected that there will be any broker non-votes at the special meeting. However, if there are any broker non-votes, they will have (i) the same effect as a vote “AGAINST” the merger proposal, (ii) no effect on the non-binding compensation advisory proposal and (iii) no effect on the adjournment proposal.

Q:

What vote is required for the approval of each of the proposals?

A:

The merger proposal.   Approval of the merger proposal requires the affirmative vote of a majority of the outstanding shares of Marathon Oil common stock entitled to vote on the proposal. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” the proposal. Failure to vote on the merger proposal will have the same effect as a vote “AGAINST” the merger proposal.

The non-binding compensation advisory proposal.   Approval of the non-binding compensation advisory proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or by proxy at the special meeting and entitled to vote on the proposal, assuming a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote. As an advisory vote, this proposal is not binding upon Marathon Oil or the Marathon Oil board or ConocoPhillips or the ConocoPhillips board, and approval of this proposal is not a condition to completion of the merger.

2

The adjournment proposal.   Approval of the adjournment proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or by proxy at the special meeting and entitled to vote on the proposal, regardless of whether a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote. Approval of this proposal is not a condition to completion of the merger.

Q:

Who will count the votes?

A:

The votes at the special meeting will be counted by an independent inspector of elections appointed by Marathon Oil.

Q:

What will Marathon Oil stockholders receive if the merger is completed?

A:

As a result of the merger, each share of Marathon Oil common stock issued and outstanding immediately prior to the effective time of the merger (other than any excluded shares and converted shares, as described in the section entitled “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80) will be converted into the right to receive, without interest, 0.255 shares of ConocoPhillips common stock (which we refer to as the “merger consideration”). We refer to such shares of Marathon Oil common stock eligible to receive the merger consideration as “eligible shares.”

If you receive the merger consideration and would otherwise be entitled to receive a fractional share of ConocoPhillips common stock, you will receive cash in lieu of such fractional share, and you will not be entitled to dividends, voting rights or any other rights in respect of such fractional share. For additional information regarding the merger consideration, see the section entitled “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80.

Q:

What will holders of Marathon Oil equity awards receive in the merger?

A:

At the effective time of the merger, outstanding Marathon Oil equity awards will be treated in accordance with the terms of the merger agreement as summarized below.

Marathon Oil Restricted Stock Unit Awards.   At the effective time of the merger, each outstanding award of restricted stock units in respect of Marathon Oil common stock that vests solely based on service (which we refer to as the “Marathon Oil RSU awards”), other than any such award granted to non-employee directors, granted under Marathon Oil’s 2019 Incentive Compensation Plan (which, as amended from time to time and including any predecessor plan, we refer to as the “Marathon Oil stock plan”) will be cancelled and converted into an award of restricted stock units in respect of ConocoPhillips common stock with substantially the same terms and conditions and covering that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (i) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger, multiplied by (ii) 0.255 (which we refer to as the “exchange ratio”).

Marathon Oil Restricted Stock Unit and Deferred Stock Unit Awards Held by Non-Employee Directors. At the effective time of the merger, each outstanding Marathon Oil RSU award and each outstanding award of deferred stock units in respect of Marathon Oil common stock (which we refer to as the “Marathon Oil DSU awards”) granted to a non-employee director of Marathon Oil pursuant to the Marathon Oil stock plan will immediately vest with respect to 100% of the shares of Marathon Oil common stock subject to such award, which shares will be converted into the right to receive (i) the merger consideration with respect to each such share and (ii) for RSUs, an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such Marathon Oil RSU award.

Marathon Oil Stock Option Awards.   At the effective time of the merger, each outstanding and vested compensatory option to purchase shares of Marathon Oil common stock (which we refer to as the “Marathon Oil option awards”) granted pursuant to the Marathon Oil stock plan will be canceled and converted into the right to receive a number of shares of ConocoPhillips common stock (rounded

down to the nearest whole share) equal to the quotient of (i) the product of (A) the excess, if any, of the merger consideration value (as defined below) over the per share exercise price of such Marathon Oil option award, multiplied by (B) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger, divided by (ii) the ConocoPhillips common stock closing price (as defined below). Any Marathon Oil option award that has an exercise price per share that is equal to or greater than the merger consideration value will be canceled for no consideration. The term “merger consideration value” means the product of (x) the exchange ratio multiplied by (y) the volume weighted average price of ConocoPhillips common stock for the five consecutive trading days ending two trading days prior to the closing date as reported by Bloomberg, L.P. (which we refer to as the “ConocoPhillips common stock closing price”).

Marathon Oil Performance Unit Awards.   At the effective time of the merger, each outstanding award of performance units denominated in shares of Marathon Oil common stock (which we refer to as the “Marathon Oil performance unit awards”) granted pursuant to the Marathon Oil stock plan will immediately vest and be converted into the right to receive (i) in the case of Marathon Oil performance unit awards that vest based on total shareholder return, (A) that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (x) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by (y) the exchange ratio and (B) an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such award or (ii) in the case of Marathon Oil performance unit awards that vest based on free cash flow, an amount in cash reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by the average daily closing price of Marathon Oil common stock during the final 30 calendar days ending on the last trading day immediately preceding the closing date (which we refer to as the “average price”); provided, however, that if any values were banked under such award based on a price per share of Marathon Oil common stock that is greater than such average price, then the higher price shall be used for such portion of the award, plus any accrued but unpaid dividend equivalents with respect to such award.

For additional information regarding the treatment of Marathon Oil equity awards, see the section entitled “The Merger Agreement — Treatment of Marathon Oil Equity Awards in the Merger” beginning on page 81.

Q:

What equity stake will Marathon Oil stockholders hold in ConocoPhillips immediately following the merger?

A:

Based on the number of issued and outstanding shares of ConocoPhillips and Marathon Oil common stock as of May 28, 2024, and the exchange ratio of 0.255 shares of ConocoPhillips common stock for each share of Marathon Oil common stock, holders of shares of Marathon Oil common stock as of immediately prior to the effective time of the merger would hold, in the aggregate, approximately 11% of the issued and outstanding shares of ConocoPhillips common stock immediately following the effective time of the merger. The exact equity stake of Marathon Oil stockholders in ConocoPhillips immediately following the effective time of the merger will depend on the number of shares of ConocoPhillips common stock and Marathon Oil common stock issued and outstanding immediately prior to the effective time of the merger, as further described in the section entitled “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80.

Q:

How does the Marathon Oil board recommend that I vote?

A:

The Marathon Oil board unanimously recommends that Marathon Oil stockholders vote “FOR” the approval of the merger proposal, “FOR” the approval of the non-binding compensation advisory proposal and “FOR” the approval of the adjournment proposal. For additional information regarding how the Marathon Oil board recommends that Marathon Oil stockholders vote, see the section entitled “The Merger — Recommendation of the Marathon Oil Board of Directors and Reasons for the Merger” beginning on page 54.

4

Q:

Do any of the officers or directors of Marathon Oil have interests in the merger that may differ from or be in addition to my interests as a Marathon Oil stockholder?

A:

Yes. In considering the recommendation of the Marathon Oil board that Marathon Oil stockholders vote to approve the merger proposal, Marathon Oil stockholders should be aware that Marathon Oil’s directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of Marathon Oil stockholders generally. The Marathon Oil board was aware of and considered these differing interests, to the extent such interests existed at the time, among other matters, in evaluating and negotiating the merger agreement and the merger and in unanimously recommending that the merger agreement be adopted by Marathon Oil stockholders. For additional information, see the section entitled “The Merger — Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72.

Q:

Why are Marathon Oil stockholders being asked to vote on named executive officer compensation?

A:

The SEC has adopted rules that require Marathon Oil to seek a non-binding advisory vote on certain compensation that may be paid or become payable to Marathon Oil’s named executive officers that is based on or otherwise relates to the merger. Marathon Oil urges its stockholders to read the section entitled “The Merger — Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72.

Q:

How many votes do I have?

A:

Each Marathon Oil stockholder of record is entitled to one vote for each share of Marathon Oil common stock held of record by him or her as of the close of business on the record date.

Q:

What constitutes a quorum for the special meeting?

A:

A quorum is the minimum number of stockholders necessary to hold a valid meeting.

The presence at the special meeting, in person or by proxy, of the holders of at least one-third of the outstanding shares of Marathon Oil common stock entitled to vote at the special meeting constitutes a quorum. If you submit a properly executed proxy card, even if you do not vote for the proposals or vote to “ABSTAIN” in respect of the proposals, your shares of Marathon Oil common stock will be counted for purposes of calculating whether a quorum is present for the transaction of business at the special meeting. Broker non-votes will not be treated as present for purposes of determining the presence of a quorum at the special meeting.

Q:

What will happen to Marathon Oil as a result of the merger?

A:

If the merger is completed, Merger Sub will merge with and into Marathon Oil. As a result of the merger, the separate corporate existence of Merger Sub will cease, and Marathon Oil will continue as the surviving corporation in the merger and as a wholly owned subsidiary of ConocoPhillips. Furthermore, shares of Marathon Oil common stock will be delisted from the NYSE and will no longer be publicly traded.

Q:

I own shares of Marathon Oil common stock. What will happen to those shares as a result of the merger?

A:

If the merger is completed, your shares of Marathon Oil common stock will be converted into the right to receive, without interest, the merger consideration. All such shares of Marathon Oil common stock, when so converted, will cease to be outstanding and will automatically be cancelled. Each holder of a share of Marathon Oil common stock that was outstanding immediately prior to the effective time of the merger will cease to have any rights with respect to shares of Marathon Oil common stock except the right to receive, without interest, the merger consideration, any dividends or distributions made with respect to shares of ConocoPhillips common stock with a record date after the effective time of the merger, and any cash to be paid in lieu of any fractional shares of ConocoPhillips common stock, in each case to be issued or paid upon the exchange of any certificates or book-entry shares of Marathon Oil common stock for the merger consideration. For additional information, see the sections

5

entitled “The Merger — Merger Consideration” beginning on page 48 and “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80.

Q:

Where will the ConocoPhillips common stock that Marathon Oil stockholders receive in the merger be publicly traded?

A:

Assuming the merger is completed, the shares of ConocoPhillips common stock that Marathon Oil stockholders receive in the merger will be listed and traded on the NYSE under the symbol “COP”.

Q:

What happens if the merger is not completed?

A:

If the merger proposal is not approved by Marathon Oil stockholders or if the merger is not completed for any other reason, Marathon Oil stockholders will not receive any merger consideration in connection with the merger, and their shares of Marathon Oil common stock will remain outstanding. Marathon Oil will remain an independent public company and Marathon Oil common stock will continue to be listed and traded on the NYSE. Additionally, if the merger proposal is not approved by Marathon Oil stockholders or if the merger is not completed for any other reason, ConocoPhillips will not issue shares of ConocoPhillips common stock to Marathon Oil stockholders. If the merger agreement is terminated under specified circumstances, Marathon Oil may be required to pay ConocoPhillips a termination fee or another termination-related payment. For a more detailed discussion of the termination-related fees, see “The Merger Agreement — Termination” beginning on page 109.

Q:

What happens if the non-binding compensation advisory proposal is not approved?

A:

This vote is advisory and non-binding, and the merger is not conditioned or dependent upon the approval of the non-binding compensation advisory proposal. However, Marathon Oil and ConocoPhillips value the opinions of Marathon Oil stockholders and ConocoPhillips expects to consider the outcome of the vote, along with other relevant factors, when considering future executive compensation, assuming the merger is completed.

Q:

What happens if the adjournment proposal is not approved?

A:

This vote is being taken in order to allow Marathon Oil stockholders to vote to adjourn the special meeting if there are not sufficient votes cast at the special meeting to approve the merger proposal. However, regardless of the results of voting for the adjournment proposal, under the Marathon Oil bylaws, the chair of the special meeting may adjourn the special meeting at his or her discretion, subject to the terms of the merger agreement.

Q:

What is a proxy?

A:

A proxy is a legal designation of another person to vote the stock you own.

Q:

How can I vote my shares without attending the special meeting?

A:

If you are a stockholder of record of Marathon Oil common stock as of the record date, you can vote by proxy by phone, the Internet or mail by following the instructions provided in the enclosed proxy card. Please note that if you are a beneficial owner, you may vote by submitting voting instructions to your broker, bank or other nominee, or otherwise by following instructions provided by your broker, bank or other nominee. Phone and Internet voting may be available to beneficial owners. Please refer to the vote instruction form provided by your broker, bank or other nominee.

Q:

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

A:

If your shares of Marathon Oil common stock are registered directly in your name with Marathon Oil’s transfer agent, Computershare Trust Company, N.A., you are considered the stockholder of record with respect to those shares, and access to proxy materials is being provided directly to you. If your shares are held in a stock brokerage account or by a broker, bank or other nominee, then you are

6

considered the beneficial owner of those shares, which are considered to be held in “street name.” Access to proxy materials is being provided to you by your broker, bank or other nominee who is considered the stockholder of record with respect to those shares.

Q:

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

A:

You may receive more than one set of voting materials relating to the special meeting if you hold shares of Marathon Oil common stock in “street name” and also directly in your name as a stockholder of record or otherwise or if you hold shares of Marathon Oil common stock in more than one brokerage account.

Direct holders (stockholders of record).   For shares of Marathon Oil common stock held directly, complete, sign, date and return each proxy card (or cast your vote by phone or the Internet as provided on each proxy card) or otherwise follow the voting instructions provided in this proxy statement/​prospectus in order to ensure that all of your shares of Marathon Oil common stock are voted.

Shares in “street name.”   For shares of Marathon Oil common stock held in “street name” through a broker, bank or other nominee, follow the instructions provided by your broker, bank or other nominee to vote your shares.

Q:

If a stockholder gives a proxy, how will shares of Marathon Oil common stock covered by the proxy be voted?

A:

If you provide a proxy, regardless of whether you provide that proxy by phone, the Internet or completing and returning the proxy card, the individuals named on the enclosed proxy card will vote all of your shares of Marathon Oil common stock represented by such proxy in the way that you indicate when providing your proxy in respect of the shares of common stock you hold in Marathon Oil. When completing the phone or Internet processes or the proxy card, you may specify whether your shares of Marathon Oil common stock should be voted for or against, or abstain from voting on, all, some or none of the specific items of business to come before the special meeting.

Q:

How will my shares of common stock be voted if I return a blank proxy?

A:

If you sign, date and return your proxy and do not indicate how you want your shares of Marathon Oil common stock to be voted, then your shares of Marathon Oil common stock will be voted “FOR” the approval of the merger proposal, “FOR” the approval of the non-binding compensation advisory proposal and “FOR” the approval of the adjournment proposal.

Q:

Can I change my vote after I have submitted my proxy?

A:

Yes. If you are a stockholder of record of Marathon Oil common stock as of the close of business on the record date, whether you vote by phone, the Internet or mail, you can change or revoke your proxy before it is voted at the special meeting in one of the following ways:

•

submit a new proxy card bearing a later date;

Q:

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

A:

Within four business days following certification of the final voting results, Marathon Oil intends to file the final voting results of its special meeting with the SEC in a Current Report on Form 8-K.

Q:

If I do not favor the merger, what are my rights?

A:

Because shares of Marathon Oil common stock are listed on the NYSE and holders of shares of Marathon Oil common stock are not required to receive consideration other than shares of ConocoPhillips common stock, which are listed on the NYSE, and cash in lieu of fractional shares in the merger, holders of shares of Marathon Oil common stock are not entitled to exercise appraisal rights under Delaware law in connection with the merger. Marathon Oil stockholders may vote against the merger proposal if they do not favor the merger.

Q:

Are there any risks that I should consider in deciding how to vote?

A:

Yes. You should read and carefully consider the risk factors set forth in the section entitled “Risk Factors” beginning on page 26. You also should read and carefully consider the risk factors of ConocoPhillips and Marathon Oil contained in the documents that are incorporated by reference in this proxy statement/prospectus.

Q:

What happens if I sell or otherwise transfer my shares of Marathon Oil common stock before the special meeting?

A:

The record date for Marathon Oil stockholders entitled to vote at the special meeting is earlier than the date of the special meeting. If you sell or otherwise transfer your shares of Marathon Oil common stock after the record date but before the special meeting, you will, unless special arrangements are made, retain your right to vote at the special meeting but will have transferred the right to receive, without interest, the merger consideration to the person to whom you transferred your shares of Marathon Oil common stock.

Q:

What are the material U.S. federal income tax consequences of the merger to Marathon Oil stockholders?

A:

Marathon Oil and ConocoPhillips intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (which we refer to as the “Code”). It is expected that U.S. holders (as defined in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 113) of shares of Marathon Oil common stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon receipt of ConocoPhillips common stock in exchange for Marathon Oil common stock in the merger, other than gain or loss, if any, with respect to any cash received in lieu of a fractional share of ConocoPhillips common stock. The completion of the merger is not conditioned on the merger qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or Internal Revenue Service (which we refer to as the “IRS”) ruling to that effect. However, in connection with the effectiveness of the registration statement of which this proxy statement/prospectus is a part, each of Kirkland & Ellis LLP, counsel to Marathon Oil, and Wachtell, Lipton, Rosen & Katz, counsel to ConocoPhillips, delivered a legal opinion to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

The material U.S. federal income tax consequences of the merger are discussed in more detail in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 113. The discussion of the material U.S. federal income tax consequences contained in this proxy statement/​prospectus is intended to provide only a general discussion and is not a complete analysis or description of all potential U.S. federal income tax consequences of the merger that may vary with, or are dependent on, individual circumstances. In addition, it does not address the effects of any foreign, state or local tax laws or any U.S. federal tax laws other than U.S. federal income tax laws.

TAX MATTERS ARE COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO YOU IN YOUR PARTICULAR CIRCUMSTANCES.

Q:

When is the merger expected to be completed?

A:

ConocoPhillips and Marathon Oil are working to complete the merger as quickly as possible. Subject to the satisfaction or waiver of the conditions described in the section entitled “The Merger Agreement — Conditions to the Completion of the Merger” ​(beginning on page 107) including the approval of the merger proposal by Marathon Oil stockholders at the special meeting and the receipt of required regulatory approvals, the transaction is expected to close in the fourth quarter of 2024. However, neither ConocoPhillips nor Marathon Oil can predict the actual date on which the merger will be completed, nor can the parties assure that the merger will be completed, because completion is subject to conditions beyond either company’s control. In addition, if the merger is not completed by May 28, 2025 (or, under certain circumstances as described in the section entitled “The Merger Agreement — Termination” ​(beginning on page 109) by November 28, 2025 or May 28, 2026), either ConocoPhillips or Marathon Oil may choose not to proceed with the merger by terminating the merger agreement.

Q:

What are the conditions to completion of the merger?

A:

The merger is subject to a number of conditions to closing as specified in the merger agreement. These closing conditions include, among others, (i) the approval of the merger proposal by Marathon Oil stockholders, (ii) the expiration or termination of any waiting period (and any extension of such period) under the Hart-Scott-Rodino Act of 1976, as amended (which we refer to as the “HSR Act”), applicable to the merger and receipt of certain non-U.S. antitrust approvals, (iii) no law or order being in effect that prohibits the consummation of the merger, (iv) the registration statement containing this proxy statement/prospectus having become effective under the Securities Act and not being the subject of any stop order or proceedings seeking a stop order and (v) the shares of ConocoPhillips common stock issuable pursuant to the merger agreement have been authorized for listing on the NYSE. More information may be found in “The Merger Agreement — Conditions to the Completion of the Merger” beginning on page 107.

Q:

If I am a Marathon Oil stockholder, how will I receive the merger consideration to which I am entitled?

A:

If you are a holder of certificates that represent eligible shares of Marathon Oil common stock (which we refer to as “Marathon Oil common stock certificates”), a notice advising you of the effectiveness of the merger and a letter of transmittal and instructions for the surrender of your Marathon Oil common stock certificates will be mailed to you as soon as practicable after the effective time of the merger. After receiving proper documentation from you, the exchange agent will send to you (i) a statement reflecting the aggregate whole number of shares of ConocoPhillips common stock (which will be in uncertificated book-entry form) that you have a right to receive pursuant to the merger agreement and (ii) a check in the amount equal to the cash payable in lieu of any fractional shares of ConocoPhillips common stock and dividends and other distributions on the shares of ConocoPhillips common stock issuable to you as merger consideration.

If you are a holder of book-entry shares representing eligible shares of Marathon Oil common stock (which we refer to as “Marathon Oil book-entry shares”) which are held through the Depository Trust Company (which we refer to as “DTC”), the exchange agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the closing date, the merger consideration, cash in lieu of any fractional shares of ConocoPhillips common stock and any dividends and other distributions on the shares of ConocoPhillips common stock issuable as merger consideration, in each case, that DTC has the right to receive.

If you are a holder of record of Marathon Oil book-entry shares which are not held through DTC, the exchange agent will deliver to you, as soon as practicable after the effective time of the merger, (i) a

9

notice advising you of the effectiveness of the merger, (ii) a statement reflecting the aggregate whole number of shares of ConocoPhillips common stock (which will be in uncertificated book-entry form) that you have a right to receive pursuant to the merger agreement and (iii) a check in the amount equal to the cash payable in lieu of any fractional shares of ConocoPhillips common stock and dividends and other distributions on the shares of ConocoPhillips common stock issuable to you as merger consideration.

No interest will be paid or accrued on any amount payable for shares of Marathon Oil common stock eligible to receive the merger consideration pursuant to the merger agreement.

For additional information on the exchange of Marathon Oil common stock for the merger consideration, see the section entitled “The Merger Agreement — Payment for Securities; Exchange” beginning on page 82.

Q:

If I am a holder of Marathon Oil common stock certificates, do I need to send in my stock certificates at this time to receive the merger consideration?

A:

No. Please DO NOT send your Marathon Oil common stock certificates with your proxy card. You should carefully review and follow the instructions set forth in the letter of transmittal, which will be mailed to you, regarding the surrender of your stock certificates.

Q:

If I am a holder of Marathon Oil common stock, will the shares of ConocoPhillips common stock issued in the merger receive a dividend?

A:

After the completion of the merger, the shares of ConocoPhillips common stock issued in connection with the merger will carry with them the right to receive the same dividends on shares of ConocoPhillips common stock as all other holders of shares of ConocoPhillips common stock, for any dividend the record date for which occurs after the merger is completed.

Q:

Who will solicit and pay the cost of soliciting proxies?

A:

Marathon Oil has retained Innisfree (which we refer to as the “Marathon Oil proxy solicitor”) to assist in the solicitation process. Marathon Oil will pay Innisfree a fee of $50,000, plus reasonable out-of-pocket expenses and fees for any additional services. Marathon Oil also has agreed to indemnify the Marathon Oil proxy solicitor against various liabilities and expenses that relate to or arise out of its solicitation of proxies (subject to certain exceptions).

Q:

What is “householding”?

A:

To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding Marathon Oil common stock but who share the same address, Marathon Oil has adopted a procedure approved by the SEC called “householding.” Under this procedure, certain stockholders of record who have the same address and last name will receive only one copy of this proxy statement/prospectus until such time as one or more of these stockholders notifies Marathon Oil that they want to receive separate copies. In addition, the broker, bank or other nominee for any stockholder who is a beneficial owner of Marathon Oil common stock may deliver only one copy of this proxy statement/prospectus to multiple stockholders who share the same address, unless that broker, bank or other nominee has received contrary instructions from one or more of the Marathon Oil stockholders. This procedure reduces duplicate mailings and saves printing costs and postage fees, as well as natural resources. Marathon Oil stockholders affected by householding will continue to have access to and utilize separate proxy voting instructions. To opt out of householding for future proxy materials, please write to Marathon Oil’s Shareholder Services Office at 990 Town and Country Boulevard, Houston, Texas 77024.

Q:

What should I do now?

A:

You should read this proxy statement/prospectus carefully and in its entirety, including the annexes, and return your completed, signed and dated proxy card by mail in the enclosed postage-paid envelope

10

or submit your voting instructions by phone or the Internet as soon as possible so that your shares of Marathon Oil common stock will be voted in accordance with your instructions.

Marathon Oil stockholders will not be entitled to receive any fractional shares of ConocoPhillips common stock in the merger, and no Marathon Oil stockholders will be entitled to dividends, voting rights or any other rights in respect of any fractional shares of ConocoPhillips common stock.

At the effective time of the merger, each outstanding and vested Marathon Oil option awards granted pursuant to the Marathon Oil stock plan will be canceled and converted into the right to receive a number of shares of ConocoPhillips common stock (rounded down to the nearest whole share) equal to the quotient of (i) the product of (A) the excess, if any, of the merger consideration value over the per share exercise price, multiplied by (B) the number of shares of Marathon Oil common stock subject to such Marathon Oil option award immediately prior to the effective time of the merger, divided by (ii) the ConocoPhillips common stock closing price. Any Marathon Oil option award that has an exercise price per share that is equal to or greater than the merger consideration value will be canceled for no consideration.

Marathon Oil Performance Unit Awards

At the effective time of the merger, each outstanding Marathon Oil performance unit award granted pursuant to the Marathon Oil stock plan will immediately vest and be converted into the right to receive (i) in the case of Marathon Oil performance unit awards that vest based on total shareholder return, (A) that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (x) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by (y) the exchange ratio and (B) an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such award or (ii) in the case of Marathon Oil performance unit awards that vest based on free cash flow, an amount in cash reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by the average daily closing price of Marathon Oil common stock during the final 30 calendar days ending on the last trading day immediately preceding the closing date; provided, however, that if any values were banked under such award based on a price per share of Marathon Oil common stock that is greater than such average price, then the higher price shall be used for such portion of the award, plus any accrued but unpaid dividend equivalents with respect to such award.

For the factors considered by the Marathon Oil board in reaching this decision and additional information on the recommendation of the Marathon Oil board, see the section entitled “The Merger — Recommendation of the Marathon Oil Board of Directors and Reasons for the Merger” beginning on page 54.

Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor (page 58)

Marathon Oil engaged Morgan Stanley & Co. LLC (“Morgan Stanley”) to act as Marathon Oil’s financial advisor in connection with the merger. Morgan Stanley delivered its oral opinion to the Marathon Oil board on May 28, 2024, which opinion was subsequently confirmed in a written opinion dated May 28, 2024, that, as of the date of such opinion, and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of the review undertaken by Morgan Stanley as set forth in its written opinion, the Merger Consideration to be received by holders of shares of Marathon Oil common stock pursuant to the Merger Agreement was fair, from a financial point of view, to the holders of Marathon Oil common stock (other than ConocoPhillips, Merger Sub and their respective affiliates).

The full text of Morgan Stanley’s written opinion, which describes, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken, is attached as Annex B to this proxy statement/prospectus and is incorporated by reference in its entirety. The summary of Morgan Stanley’s opinion contained in this proxy statement/prospectus is qualified in its entirety by reference to the full text of the opinion. Marathon Oil stockholders are encouraged to read Morgan Stanley’s opinion carefully in its entirety. Morgan Stanley’s opinion was directed to the

14

Marathon Oil board, in its capacity as such, and addressed only the fairness from a financial point of view to the holders of Marathon Oil common stock (other than ConocoPhillips, Merger Sub and their respective affiliates) of the merger consideration pursuant to the merger agreement as of the date of such opinion. Morgan Stanley’s opinion did not address any other aspects or implications of the merger. Morgan Stanley’s opinion did not in any manner address the price at which Marathon Oil common stock or ConocoPhillips common stock would trade following the consummation of the merger or at any time, and Morgan Stanley expressed no opinion or recommendation to any holder of shares of Marathon Oil common stock as to how such holder should vote at the special meeting, or whether to take any other action with respect to the merger.

For a further discussion of the opinion that the Marathon Oil board received from Morgan Stanley, see the section entitled “The Merger — Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor” beginning on page 58 of this proxy statement/prospectus and the full text of the written opinion of Morgan Stanley attached as Annex B to this proxy statement/prospectus.

Special Meeting of Marathon Oil Stockholders (page 41)

Date, Time, Place and Purpose of the Special Meeting

The special meeting will be held on August 29, 2024, at 8:00 a.m., Central Time in the Level 6 Auditorium of One MRO, located at 990 Town & Country Blvd in Houston, Texas 77024.

The purpose of the special meeting is to consider and vote on the merger proposal, the non-binding compensation advisory proposal and the adjournment proposal. Approval of the merger proposal is a condition to the obligation of Marathon Oil and ConocoPhillips to complete the merger. Approval of the non-binding compensation advisory proposal and the adjournment proposal are not conditions to the obligation of either Marathon Oil or ConocoPhillips to complete the merger.

Record Date and Outstanding Shares of Marathon Oil Common Stock

Only holders of record of issued and outstanding shares of Marathon Oil common stock as of the close of business on July 26, 2024, the record date for the special meeting, are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of the special meeting.

As of the record date, there were 559,383,423 shares of Marathon Oil common stock issued and outstanding and entitled to vote at the special meeting. You may cast one vote for each share of Marathon Oil common stock that you held as of the close of business on the record date.

A complete list of Marathon Oil stockholders entitled to vote at the special meeting will be available for inspection at Marathon Oil’s principal place of business during regular business hours for a period of no less than 10 days before the special meeting at 990 Town and Country Boulevard Houston, Texas 77024.

Quorum; Abstentions and Broker Non-Votes

A quorum of Marathon Oil stockholders is necessary for Marathon Oil to hold a valid meeting. The presence at the special meeting, in person or by proxy, of the holders of at least one-third of the outstanding shares of Marathon Oil common stock entitled to vote at the special meeting constitutes a quorum.

If you submit a properly executed proxy card, even if you do not vote for any of the proposals or vote to “ABSTAIN” in respect of each proposal, your shares of Marathon Oil common stock will be counted for purposes of calculating whether a quorum is present for the transaction of business at the special meeting. Marathon Oil common stock held in “street name” with respect to which the beneficial owner fails to give voting instructions to the broker, bank or other nominee, and Marathon Oil common stock with respect to which the beneficial owner otherwise fails to vote, will not be considered present and entitled to vote at the special meeting for the purpose of determining the presence of a quorum.

A broker non-vote will result if your broker, bank or other nominee returns a proxy but does not provide instruction as to how shares should be voted on a particular matter. It is not expected that there will be any broker non-votes at the special meeting. However, if there are any broker non-votes, the shares will

15

not be considered present and entitled to vote at the special meeting for the purpose of determining the presence of a quorum.

Executed but unvoted proxies will be voted in accordance with the recommendations of the Marathon Oil board (i.e., “FOR” all of the proposals).

Required Vote to Approve the Merger Proposal

Approval of the merger proposal requires the affirmative vote of a majority of the outstanding shares of Marathon Oil common stock entitled to vote on the proposal. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” the merger proposal. Failure to vote on the merger proposal will have the same effect as a vote “AGAINST” the merger proposal.

Required Vote to Approve the Non-Binding Compensation Advisory Proposal

Approval of the non-binding compensation advisory proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, assuming a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and failure to vote and broker non-votes will have no effect on the outcome of the vote.

Required Vote to Approve the Adjournment Proposal

Approval of the adjournment proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, regardless of whether a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and failure to vote and broker non-votes will have no effect on the outcome of the vote.

Each of the merger proposal, the non-binding compensation advisory proposal and the adjournment proposal are further described in the section entitled “Marathon Oil Proposals” beginning on page 46.

Voting by Directors and Executive Officers

As of July 16, 2024, Marathon Oil directors and executive officers, and their affiliates, as a group, owned and were entitled to vote 1,936,910 shares of Marathon Oil common stock, or less than 1% of the total outstanding shares of Marathon Oil common stock as of such date.

Marathon Oil currently expects that all of its directors and executive officers will vote their shares “FOR” the merger proposal, “FOR” the non-binding compensation advisory proposal and “FOR” the adjournment proposal.

Adjournment

If the adjournment proposal is approved by the requisite number of votes at the special meeting, and there are not sufficient votes for the approval of the merger proposal, Marathon Oil expects that the special meeting will be adjourned to solicit additional proxies in accordance with the merger agreement. The adjourned meeting may take place without further notice other than by an announcement made at the special meeting. In a subsequent reconvening of the special meeting, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Regardless of the results of voting for the adjournment proposal, the Marathon Oil bylaws allow the chair of the special meeting to adjourn the special meeting at his or her discretion, subject to the terms of the merger agreement.

For additional information, see the section entitled “Special Meeting of Marathon Oil Stockholders” beginning on page 41.

Board of Directors and Management of ConocoPhillips Following the Completion of the Merger (page 72)

Upon the completion of the merger, the current directors and executive officers of ConocoPhillips are expected to continue in their current positions, other than as may be publicly announced by ConocoPhillips in the normal course.

Interests of Marathon Oil Directors and Executive Officers in the Merger (page 72)

In considering the recommendation of the Marathon Oil board with respect to the proposals at the special meeting, Marathon Oil stockholders should be aware that the directors and executive officers of Marathon Oil may have interests in the merger that may be different from, or in addition to, the interests of Marathon Oil stockholders generally. The members of the Marathon Oil board were aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement, in approving the merger agreement and in determining to recommend that Marathon Oil stockholders approve the merger proposal.

For additional information, see the section entitled “The Merger — Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72.

No Solicitation; Changes of Recommendation (page 92)

No Solicitation

From and after May 28, 2024, Marathon Oil, its subsidiaries and their respective officers and directors must, and must use their reasonable best efforts to cause the other representatives of Marathon Oil and its subsidiaries to, immediately cease, and cause to be terminated, any discussion or negotiations ongoing with any third party with respect to any inquiry, proposal or offer that constitutes, or could reasonably be expected to lead to, a competing proposal (as defined below).

From and after May 28, 2024, Marathon Oil, its subsidiaries and their respective officers and directors may not, and must use their reasonable best efforts to cause the other representatives of Marathon Oil and its subsidiaries not to, directly or indirectly:

•

initiate, solicit, propose, knowingly encourage, or knowingly facilitate any inquiry or the making of any proposal or offer that constitutes, or could reasonably be expected to result in, a competing proposal;

•

engage in, continue or otherwise participate in any discussions with any person with respect to or negotiations with any person with respect to, relating to, or in furtherance of a competing proposal or any inquiry, proposal or offer that could reasonably be expected to lead to a competing proposal;

•

furnish any information regarding Marathon Oil or its subsidiaries, or access to the properties, assets or employees of Marathon Oil or its subsidiaries, to any person in connection with or in response to any competing proposal or any inquiry, proposal or offer that could reasonably be expected to lead to a competing proposal;

•

enter into any letter of intent or agreement in principle, or other agreement providing for a competing proposal (other than certain confidentiality agreements entered into as permitted by the merger agreement); or

•

submit any proposal for a competing transaction to the vote of Marathon Oil stockholders.

Notwithstanding the agreements described above, prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, Marathon Oil and its representatives may engage in the

18

activities described in the second and third bullets directly above this paragraph with any person if (i) Marathon Oil receives a bona fide written competing proposal from such person that was not solicited at any time after May 28, 2024; and (ii) such competing proposal did not arise from a material breach of Marathon Oil’s non-solicitation obligations (which are described in “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation” beginning on page 92); provided, however, that:

•

no information that is prohibited from being furnished pursuant to the “no solicitation” obligations under the merger agreement (which are described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation” beginning on page 92) may be furnished until Marathon Oil receives an executed confidentiality agreement, subject to certain conditions, including that the limitations in such confidentiality agreement on the use and disclosure of non-public information furnished to such person are no less favorable in all material respects to Marathon Oil than the terms of the Confidentiality Agreement, dated May 10, 2024, between ConocoPhillips and Marathon Oil, as determined by the Marathon Oil board in good faith after consultation with its legal counsel;

•

any non-public information furnished to such person will have previously been made available to ConocoPhillips or is made available to ConocoPhillips prior to or concurrently with the time such information is made available to such person (or in the case of oral non-public information only, promptly (and in any event within 24 hours) after);

•

prior to taking any such actions, the Marathon Oil board or any committee of the Marathon Oil board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such competing proposal is, or would reasonably be expected to lead to, a superior proposal (as defined below); and

•

prior to taking any such actions, the Marathon Oil board determines in good faith after consultation with its outside legal counsel that failure to take such action would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law.

Notwithstanding the above restrictions, Marathon Oil or any of its representatives may, in response to an inquiry or proposal from a third party, inform a third party or its representative of the “no solicitation” obligations described above (without conveying, requesting or attempting to gather any other information except as otherwise specifically permitted under the merger agreement).

A “competing proposal” means any contract, proposal, offer or indication of interest relating to any transaction or series of related transactions (other than transactions only with ConocoPhillips or any of its subsidiaries) involving, directly or indirectly:

•

any acquisition (by asset purchase, stock purchase, merger or otherwise) by any third party or group of any business or assets of Marathon Oil or any of its subsidiaries (including capital stock of or ownership interest in any subsidiary) that generated 20% or more of the value of Marathon Oil’s and its subsidiaries’ assets (by fair market value), net revenue or EBITDA for the preceding 12 months, or any license, lease or long-term supply agreement having a similar economic effect;

•

any acquisition of beneficial ownership by any third party or group of 20% or more of the outstanding shares of Marathon Oil common stock or any other securities entitled to vote on the election of directors or any tender or exchange offer that would result in any person or group beneficially owning 20% or more of the outstanding shares of Marathon Oil common stock or any other securities entitled to vote on the election of directors; or

•

any merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving Marathon Oil or any of its subsidiaries.

A “superior proposal” means a bona fide written competing proposal (with references in the definition thereof to “20% or more” being deemed to be replaced with references to “all or substantially all”) that is not solicited after May 28, 2024 that, in the good faith determination of the Marathon Oil board, after consultation with its outside legal and financial advisors:

19

•

is more favorable to Marathon Oil’s stockholders from a financial point of view than the merger (after taking into account the time likely to be required to consummate such proposal and any adjustments or revisions to the terms of the merger agreement offered by ConocoPhillips in response to such proposal or otherwise);

•

is reasonably likely to be consummated on the terms proposed, taking into account any legal, financial, regulatory and stockholder approval requirements, the sources, availability and terms of any financing, financing market conditions and the existence of a financing contingency, the likelihood of termination, the timing of closing, the identity of the person or persons making the proposal and any other aspects considered relevant by the Marathon Oil board; and

•

if applicable, for which financing is fully committed or reasonably determined to be available by the Marathon Oil board.

Changes of Recommendation

Subject to certain exceptions described below, the Marathon Oil board may not effect a recommendation change (as such term is defined in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — Restrictions on Changes of Recommendation” beginning on page 93).

Permitted Changes of Recommendation and Termination of Merger Agreement in Connection with a Superior Proposal

Prior to, but not after, the merger proposal has been approved by Marathon Oil stockholders, in response to a bona fide written competing proposal from a third party that was not solicited at any time following May 28, 2024 and did not arise from a material breach of the obligations described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation” (beginning on page 92) if the Marathon Oil board so chooses, the Marathon Oil board may effect a recommendation change or terminate the merger agreement to enter into a definitive agreement with respect to such proposal, provided, however, that such a change of recommendation or termination of the merger agreement, as applicable, may not be made unless and until:

•

the Marathon Oil board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such competing proposal is a superior proposal and, after consultation with its outside legal counsel, that the failure to effect a recommendation change in response to such superior proposal or terminate the merger agreement to enter into a definitive agreement with respect to such superior proposal would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law; and

•

Marathon Oil provides ConocoPhillips written notice of such proposed action and the basis of such proposed action five business days in advance and complies with certain obligations, each as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — Permitted Changes of Recommendation in Connection with a Superior Proposal” beginning on page 94.

Permitted Changes of Recommendation in Connection with Intervening Events

Prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, in response to an intervening event (as defined below) that occurs or arises after May 28, 2024 and that did not arise from or in connection with a breach of the merger agreement by Marathon Oil, Marathon Oil may, if the Marathon Oil board so chooses, effect a recommendation change (but may not terminate the merger agreement) if:

•

the Marathon Oil board determines in good faith, after consultation with its financial advisors and outside legal counsel, that an intervening event has occurred and, after consultation with its outside legal counsel, that failure to effect a recommendation change in response to such intervening event would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law; and

20

•

Marathon Oil provides ConocoPhillips written notice of such proposed action and the basis of such proposed action five business days in advance (including a reasonably detailed description of the facts and circumstances of the intervening event) and complies with certain obligations, each as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — Permitted Changes of Recommendation in Connection with Intervening Events” beginning on page 95.

An “intervening event” is a material development or change in circumstance that occurs or arises after May 28, 2024 that was not known to or reasonably foreseeable by the Marathon Oil board as of May 28, 2024 (or, if known or reasonably foreseeable, the magnitude or material consequences of which were not known or reasonably foreseeable by the Marathon Oil board as of May 28, 2024); except that in no event will (i) the receipt, existence or terms of an actual or possible competing proposal or superior proposal, (ii) any effect relating to ConocoPhillips or any of its subsidiaries that does not amount to a material adverse effect, individually or in the aggregate, (iii) any change, in and of itself, in the price or trading volume of shares of Marathon Oil common stock or ConocoPhillips common stock (it being understood that the underlying facts giving rise or contributing to such change may be taken into account in determining whether there has been an intervening event, to the extent otherwise permitted by this definition), (iv) the fact that Marathon Oil or any of its subsidiaries exceeds (or fails to meet) internal or published projections or guidance or any matter relating thereto or of consequence thereof (it being understood that the underlying facts giving rise or contributing to such change may be taken into account in determining whether there has been an intervening event, to the extent otherwise permitted by this definition) or (v) conditions (or changes in such conditions) in the oil and gas exploration and production industry (including changes in commodity prices, general market prices and political or regulatory changes affecting the industry or any changes in applicable law), constitute an intervening event.

Termination (page 109)

ConocoPhillips and Marathon Oil may terminate the merger agreement and abandon the merger at any time prior to the effective time of the merger by mutual written consent of ConocoPhillips and Marathon Oil.

The merger agreement may also be terminated by either ConocoPhillips or Marathon Oil at any time prior to the effective time of the merger in any of the following situations:

•

if any governmental entity having jurisdiction over any party has issued any order, decree, ruling or injunction or taken any other action permanently restraining, enjoining or otherwise prohibiting the consummation of the merger and such order, decree, ruling or injunction or other action has become final and nonappealable, or if any law has been adopted that permanently makes the consummation of the merger illegal or otherwise permanently prohibited, so long as the terminating party has not breached any material covenant or agreement under the merger agreement that has caused or resulted in such order, decree, ruling or injunction or other action;

•

if the merger has not been consummated on or before May 28, 2025 (or, under certain circumstances as described in the section entitled “The Merger Agreement — Termination” ​(beginning on page 109) by November 28, 2025 or May 28, 2026) (which we refer to as the “end date termination event”);

•

if the Marathon Oil stockholders do not approve the merger proposal upon a vote held at a duly held special meeting, or at any adjournment or postponement of the special meeting (which we refer to as a “stockholder approval termination event”); or

•

in the event of a breach by the other party of any representation, warranty, covenant or other agreement contained in the merger agreement which would give rise to the failure of an applicable closing condition (and such breach is not curable prior to the end date, or if curable prior to the end date, has not been cured by the earlier of (i) 30 days after the giving of written notice to the breaching party of such breach and (ii) two business days prior to the end date); provided, however, that the terminating party is not itself then in breach of the merger agreement that permits termination of the merger agreement by the other party (which, in the case of a breach by Marathon Oil, we refer to as a “Marathon Oil breach termination event”).

21

In addition, the merger agreement may be terminated by ConocoPhillips:

•

if prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, the Marathon Oil board or a committee of the Marathon Oil board has effected a recommendation change; or

•

if Marathon Oil, its subsidiaries or any of Marathon Oil’s directors or executive officers has materially breached Marathon Oil’s “no solicitation” obligations under the merger agreement (as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation” beginning on page 92) (which we refer to as a “no solicitation breach termination event”).

Further, the merger agreement may be terminated by Marathon Oil:

•

if prior to, but not after, the approval of the merger proposal by Marathon Oil stockholders, to enter into a definitive agreement with respect to a superior proposal, provided that Marathon Oil has (i) complied in all material respects with its “no solicitation” obligations under the merger agreement as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation” ​(beginning on page 92) and (ii) pays ConocoPhillips the termination fee as required under the merger agreement and described in the section entitled “The Merger Agreement — Termination — Termination Fees and Expenses” ​(beginning on page 111) (which we refer to as a “superior proposal termination event”).

Termination Fees and Expenses (page 111)

The merger agreement requires Marathon Oil to pay ConocoPhillips a termination fee of $557 million (which we refer to as the “termination fee”) if:

•

ConocoPhillips terminates the merger agreement due to a recommendation change by Marathon Oil’s board or due to a no solicitation breach termination event;

•

Marathon Oil terminates the merger agreement due to a superior proposal termination event; or

•

(i) (A) ConocoPhillips or Marathon Oil terminates the merger agreement due to a stockholder approval termination event and on or before the date of any such termination a competing proposal was publicly announced or publicly disclosed and not publicly withdrawn without qualification at least seven business days prior to the special meeting or (B) Marathon Oil or ConocoPhillips terminates the merger agreement due to an end date termination event or ConocoPhillips terminates the merger agreement due to a Marathon Oil breach termination event and following May 28, 2024 and on or before the date of any such termination a competing proposal has been announced, disclosed or otherwise communicated to the Marathon Oil board and not withdrawn without qualification at least seven business days prior to the date of such termination and (ii) within 12 months after the date of such termination, Marathon Oil enters into a definitive agreement with respect to a competing proposal (or publicly approves or recommends to the Marathon Oil stockholders or otherwise does not oppose, in the case of a tender or exchange offer, a competing proposal) or consummates a competing proposal. For a further description of this provision, see the section entitled “The Merger Agreement — Termination — Termination Fees and Expenses” beginning on page 111.

The merger agreement also requires Marathon Oil to pay $86 million to ConocoPhillips for its transaction-related expenses (which we refer to as the “expense reimbursement fee”) if either Marathon Oil or ConocoPhillips terminates the merger agreement due to a stockholder approval termination event.

In no event will ConocoPhillips be entitled to receive more than one termination fee or more than one expense reimbursement fee. If ConocoPhillips receives a termination fee, it will not be entitled to receive an expense reimbursement fee. Any expense reimbursement fee paid by Marathon Oil will be credited against any termination fee that is or may eventually become payable by Marathon Oil.

Regulatory Approvals (page 70)

The completion of the merger is subject to the receipt of antitrust clearance in the United States and certain other foreign regulatory approvals. Under the HSR Act and the rules promulgated thereunder, the

22

merger may not be completed until notification and report forms have been filed with the Federal Trade Commission (which we refer to as the “FTC”) and the Department of Justice (which we refer to as the “DOJ”) and the applicable waiting period (or any extension of such waiting period) has expired or been terminated. A transaction notifiable under the HSR Act may not be completed until the expiration of a 30-calendar-day waiting period following the parties’ filings of their respective HSR Act notification forms or the early termination of that waiting period. After the expiration of the initial waiting period (or the re-started initial waiting period), the DOJ or the FTC may issue a Request for Additional Information and Documentary Material (which we refer to as a “second request”). If a second request is issued, the parties may not complete the merger until they substantially comply with the second request and observe a second 30-calendar-day waiting period, unless the waiting period is terminated earlier or extended by the parties.

On June 11, 2024, each of ConocoPhillips and Marathon Oil filed notification and report forms under the HSR Act with the FTC and the DOJ with respect to the merger. On July 11, 2024, ConocoPhillips and Marathon Oil each received a second request from the FTC in connection with the FTC’s review of the merger.

In addition, the German Federal Cartel Office (which we refer to as the “Bundeskartellamt”) and certain other non-U.S. governmental authorities must approve the merger. On July 16, 2024, ConcocoPhillips and Marathon Oil received clearance on the merger from the Bundeskartellamt.

For additional information, see the sections entitled “The Merger — Regulatory Approvals” beginning on page 70 and “The Merger Agreement — HSR and Other Regulatory Approvals” beginning on page 99.

Accounting Treatment of the Merger (page 77)

ConocoPhillips and Marathon Oil prepare their respective financial statements in accordance with GAAP. The accounting guidance for business combinations requires the use of the acquisition method of accounting for the merger, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any. ConocoPhillips will be treated as the acquirer for accounting purposes.

Specific Performance; Remedies (page 112)

ConocoPhillips, Marathon Oil and Merger Sub have agreed that each will be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of the merger agreement and to enforce specifically the terms and provisions of the merger agreement.

No Appraisal Rights (page 149)

No appraisal rights will be available to Marathon Oil stockholders with respect to the transactions contemplated by the merger agreement.

Material U.S. Federal Income Tax Consequences of the Merger (page 113)

Marathon Oil and ConocoPhillips intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is expected that U.S. holders (as defined in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 113) of shares of Marathon Oil common stock generally will not recognize any gain or loss for U.S. federal income tax purposes upon receipt of ConocoPhillips common stock in exchange for Marathon Oil common stock in the merger, other than gain or loss, if any, with respect to any cash received in lieu of a fractional share of ConocoPhillips common stock. The completion of the merger is not conditioned on the merger qualifying for the intended tax treatment or upon the receipt of an opinion of counsel or IRS ruling to that effect. However, in connection with the effectiveness of the registration statement of which this proxy statement/​prospectus is a part, each of Kirkland & Ellis LLP, counsel to Marathon Oil, and Wachtell, Lipton, Rosen & Katz, counsel to ConocoPhillips, delivered a legal opinion to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

The material U.S. federal income tax consequences of the merger are discussed in more detail in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 113.

23

The discussion of the material U.S. federal income tax consequences contained in this proxy statement/​prospectus is intended to provide only a general discussion and is not a complete analysis or description of all potential U.S. federal income tax consequences of the merger that may vary with, or are dependent on, individual circumstances. In addition, it does not address the effects of any foreign, state or local tax laws or any U.S. federal tax laws other than U.S. federal income tax laws.

TAX MATTERS ARE COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES AS A RESULT OF THE MERGER TO YOU IN YOUR PARTICULAR CIRCUMSTANCES.

Litigation Relating to the Merger (page 78)

Although Marathon Oil and ConocoPhillips are not aware of any pending or threatened lawsuits relating to the transactions contemplated by the merger agreement as of the date of this proxy statement/​prospectus, lawsuits arising out of the transactions contemplated by the merger agreement could be filed in the future.

As of the date of this proxy statement/prospectus, Marathon Oil has received demand letters from purported stockholders of Marathon Oil alleging deficiencies and/or omissions in the preliminary proxy statement/prospectus forming part of this registration statement. The demand letters seek additional disclosures to remedy these purported deficiencies. Marathon Oil and ConocoPhillips believe that the allegations in these letters are without merit.

Comparison of Stockholders’ Rights (page 138)

The rights of Marathon Oil stockholders who receive shares of ConocoPhillips common stock in the merger will be governed by the Amended and Restated Certificate of Incorporation of ConocoPhillips (which we refer to as the “ConocoPhillips certificate of incorporation”) and the Second Amended and Restated By-Laws of ConocoPhillips (which we refer to as the “ConocoPhillips bylaws”), rather than by the Restated Certificate of Incorporation of Marathon Oil (which we refer to as the “Marathon Oil certificate of incorporation”) and the Amended and Restated Bylaws of Marathon Oil (which we refer to as the “Marathon Oil bylaws”). As a result, Marathon Oil stockholders will have different rights once they become ConocoPhillips stockholders due to the differences in the organizational documents of Marathon Oil and ConocoPhillips. The key differences are described in the section entitled “Comparison of Stockholders’ Rights” beginning on page 138.

Listing of ConocoPhillips Common Stock; Delisting and Deregistration of Marathon Oil Shares (page 77)

If the merger is completed, the shares of ConocoPhillips common stock to be issued in the merger will be listed for trading on the NYSE, shares of Marathon Oil common stock will be delisted from the NYSE and deregistered under the Exchange Act, and Marathon Oil will no longer be required to file periodic reports with the SEC pursuant to the Exchange Act.

Comparative Market Price Data

The following table sets forth the closing sales prices per share of ConocoPhillips and Marathon Oil, respectively, on the NYSE on May 28, 2024, the last trading day prior to the public announcement of the merger, and on July 26, 2024, the last practicable trading day prior to the mailing of this proxy statement/​prospectus. The table also shows the estimated implied value of the merger consideration proposed for each share of Marathon Oil common stock as of the same two dates. The implied value for the merger consideration was calculated by multiplying the closing sales price of a share of ConocoPhillips common stock on the relevant date by the exchange ratio of 0.255 shares of ConocoPhillips common stock for each share of Marathon Oil common stock.

24

The value of the merger consideration to be received in exchange for each share of Marathon Oil common stock will fluctuate with the market value of Marathon Oil common stock until the transaction is complete.

​	ConocoPhillips Common Stock			Marathon Oil Common Stock			Implied per Share Value of Merger Consideration
May 28, 2024	​	$	118.96	​	$	26.45	​	$	30.33
July 26, 2024	​	$	110.86	​	$	27.87	​	$	28.27

RISK FACTORS

In addition to the other information contained in or incorporated by reference herein, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 37, Marathon Oil stockholders should carefully consider the following risks before deciding how to vote with respect to the merger proposal, the non-binding compensation advisory proposal and the adjournment proposal to be considered and voted on at the special meeting. Marathon Oil stockholders should also consider the other information in this proxy statement/prospectus and the other documents incorporated by reference herein, particularly the risk factors contained in ConocoPhillips’ and Marathon Oil’s respective Annual Reports on Form 10-K and subsequent Quarterly Reports on Form 10-Q. For additional information, see the section entitled “Where You Can Find More Information” beginning on page 157.

Because the exchange ratio is fixed and because the market price of ConocoPhillips common stock may fluctuate, Marathon Oil stockholders cannot be certain of the precise value of any merger consideration they may receive in the merger.

At the time the merger is completed, each issued and outstanding eligible share of Marathon Oil common stock will be converted into the right to receive the merger consideration of 0.255 shares of ConocoPhillips common stock. The exchange ratio for the merger consideration is fixed, and there will be no adjustment to the merger consideration for changes in the market price of ConocoPhillips common stock or Marathon Oil common stock prior to the completion of the merger. If the merger is completed, there will be a time lapse between each of the date of this proxy statement/prospectus, the date on which Marathon Oil stockholders vote to approve the merger proposal at the special meeting and the date on which Marathon Oil stockholders entitled to receive the merger consideration actually receive the merger consideration. The market value of shares of ConocoPhillips common stock may fluctuate during and after these periods as a result of a variety of factors, including general market and economic conditions, changes in ConocoPhillips’ businesses, operations and prospects and regulatory considerations. Such factors are difficult to predict, and in many cases, may be beyond the control of ConocoPhillips and Marathon Oil. Consequently, at the time Marathon Oil stockholders must decide whether to approve the merger proposal, they will not know the actual market value of any merger consideration they will receive when the merger is completed. The actual value of any merger consideration received by Marathon Oil stockholders at the completion of the merger will depend on the market value of the shares of ConocoPhillips common stock at that time. This market value may differ, possibly materially, from the market value of shares of ConocoPhillips common stock at the time the merger agreement was entered into or at any other time. Marathon Oil stockholders should obtain current stock quotations for shares of ConocoPhillips common stock before voting their shares of Marathon Oil common stock. For additional information about the merger consideration, see the sections entitled “The Merger — Merger Consideration” beginning on page 48 and “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80.

The market price of ConocoPhillips common stock will continue to fluctuate after the merger.

Upon completion of the merger, holders of Marathon Oil common stock who receive merger consideration will become holders of shares of ConocoPhillips common stock. The market price of ConocoPhillips common stock may fluctuate significantly following completion of the merger and holders of Marathon Oil common stock could lose some or all of the value of their investment in ConocoPhillips common stock. In addition, the stock market has experienced significant price and volume fluctuations in recent times which, if they continue to occur, could have a material adverse effect on the market for, or liquidity of, the ConocoPhillips common stock, regardless of ConocoPhillips’ actual operating performance.

The market price of ConocoPhillips common stock may be affected by factors different from those that historically have affected Marathon Oil common stock.

Upon completion of the merger, holders of Marathon Oil common stock who receive merger consideration will become holders of ConocoPhillips common stock. The businesses of ConocoPhillips differ from those of Marathon Oil in certain respects, and, accordingly, the financial position or results of operations and/or cash flows of ConocoPhillips after the merger, as well as the market price of ConocoPhillips

26

common stock, may be affected by factors different from those currently affecting the financial position or results of operations and/or cash flows of Marathon Oil. Following the completion of the merger, Marathon Oil will be part of a larger company, so decisions affecting Marathon Oil may be made in respect of the larger combined business as a whole rather than the Marathon Oil businesses individually. For a discussion of the businesses of ConocoPhillips and Marathon Oil and of some important factors to consider in connection with those businesses, see the section entitled “Information about the Companies” beginning on page 40 and the documents incorporated by reference in the section entitled “Where You Can Find More Information” beginning on page 157 including, in particular, the risk factors discussed in each of ConocoPhillips’ and Marathon Oil’s Annual Reports on Form 10-K for the year ended December 31, 2023 and subsequent Quarterly Reports on Form 10-Q.

Marathon Oil stockholders will have a reduced ownership and voting interest in the combined company after the merger compared to their ownership in Marathon Oil and will exercise less influence over management.

Currently, Marathon Oil stockholders have the right to vote in the election of the Marathon Oil board and the power to approve or reject any matters requiring stockholder approval under Delaware law and the Marathon Oil certificate of incorporation and bylaws. Upon completion of the merger, each Marathon Oil stockholder who receives shares of ConocoPhillips common stock in the merger will become a stockholder of ConocoPhillips with a percentage ownership of ConocoPhillips that is smaller than the Marathon Oil stockholder’s current percentage ownership of Marathon Oil. Based on the number of issued and outstanding shares of ConocoPhillips common stock and shares of Marathon Oil common stock as of May 28, 2024 and the exchange ratio of 0.255, after the merger Marathon Oil stockholders are expected to become owners of approximately 11% of the outstanding shares of ConocoPhillips common stock. Even if all former Marathon Oil stockholders voted together on all matters presented to ConocoPhillips stockholders from time to time, the former Marathon Oil stockholders would exercise significantly less influence over ConocoPhillips after the completion of the merger relative to their influence over Marathon Oil prior to the completion of the merger, and thus would have a less significant impact on the approval or rejection of future ConocoPhillips proposals submitted to a stockholder vote.

The merger may not be completed and the merger agreement may be terminated in accordance with its terms.

The merger is subject to a number of conditions that must be satisfied or waived prior to the completion of the merger, which are described in the section entitled “The Merger Agreement — Conditions to the Completion of the Merger” beginning on page 107. These conditions to the completion of the merger may not be satisfied or waived in a timely manner or at all, and, accordingly, the merger may be delayed or may not be completed. Many of the conditions to completion of the merger are not within either Marathon Oil’s or ConocoPhillips’ control, and neither company can predict when, or if, these conditions will be satisfied. Furthermore, the requirements for obtaining the required clearances and approvals could delay the completion of the merger for a significant period of time or prevent the merger from occurring. Any delay in completing the merger may adversely affect the cost savings and other benefits that the companies expect to achieve if the merger and the integration of the companies’ respective businesses are not completed within the expected time frame.

In addition, if the merger is not completed by the end date (as defined in the section entitled “The Merger Agreement — Termination” beginning on page 109) either ConocoPhillips or Marathon Oil may choose not to proceed with the merger by terminating the merger agreement, and the parties can mutually decide to terminate the merger agreement at any time, before or after stockholder approval. In addition, ConocoPhillips and Marathon Oil may elect to terminate the merger agreement in certain other circumstances as further detailed in the section entitled “The Merger Agreement — Termination” beginning on page 109.

The merger agreement limits Marathon Oil’s ability to pursue alternatives to the merger, may discourage certain other companies from making favorable alternative transaction proposals and, in specified circumstances, could require Marathon Oil to pay ConocoPhillips a termination fee or expense reimbursement fee.

The merger agreement contains provisions that may discourage a third party from submitting a competing proposal that might result in greater value to Marathon Oil’s stockholders than the merger or may result in a potential competing acquirer of Marathon Oil proposing to pay a lower per share price to

27

acquire Marathon Oil than it might otherwise have proposed to pay. These provisions include a general prohibition on Marathon Oil from soliciting or, subject to certain exceptions relating to the exercise of fiduciary duties by the Marathon Oil board, entering into discussions with any third party regarding any competing proposal or offer for a competing transaction and ConocoPhillips generally has a right to match any competing proposals that may be made. Further, even if the Marathon Oil board withholds, withdraws, qualifies or modifies its recommendation with respect to the merger proposal, unless the merger agreement has been terminated in accordance with its terms, Marathon Oil will still have an obligation to submit the merger proposal to a vote by its stockholders. The merger agreement further provides that under specified circumstances, including after a change of recommendation by the Marathon Oil board and a subsequent termination of the merger agreement by ConocoPhillips in accordance with its terms or a termination by Marathon Oil to enter into a definitive agreement with respect to a superior proposal, Marathon Oil must pay ConocoPhillips a termination fee. Additionally, in other circumstances, even if Marathon Oil is not required to pay a termination fee, it could still be required to pay ConocoPhillips the expense reimbursement fee.

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

For additional information, see the sections entitled “The Merger Agreement — No Solicitation; Changes of Recommendation” beginning on page 92 and “The Merger Agreement — Termination” beginning on page 109.

Failure to complete the merger could negatively impact the price of shares of Marathon Oil common stock, as well as Marathon Oil’s future businesses and financial results.

The merger agreement contains a number of conditions that must be satisfied or waived prior to the completion of the merger, which are described in the section entitled “The Merger Agreement — Conditions to the Completion of the Merger” beginning on page 107. There can be no assurance that all of the conditions to the completion of the merger will be so satisfied or waived. If these conditions are not satisfied or waived, ConocoPhillips and Marathon Oil will be unable to complete the merger.

If the merger is not completed for any reason, including the failure to receive the required approval of the Marathon Oil stockholders, Marathon Oil’s business and financial results may be adversely affected, including as follows:

•

Marathon Oil may experience negative reactions from the financial markets, including negative impacts on the market price of Marathon Oil common stock;

•

the manner in which industry contacts, business partners and other third parties perceive Marathon Oil may be negatively impacted, which in turn could affect Marathon Oil’s marketing operations or its ability to compete for new business or obtain renewals in the marketplace more broadly;

•

Marathon Oil may experience negative reactions from employees; and

•

Marathon Oil will have expended time and resources that could otherwise have been spent on its existing business and the pursuit of other opportunities that could have been beneficial to the company, and Marathon Oil’s ongoing business and financial results may be adversely affected.

In addition to the above risks, if the merger agreement is terminated and the Marathon Oil board seeks an alternative transaction, Marathon Oil’s stockholders cannot be certain that Marathon Oil will be able to find a party willing to engage in a transaction on more attractive terms than the merger. If the merger agreement is terminated under specified circumstances, Marathon Oil may be required to pay ConocoPhillips a termination fee or expense reimbursement fee. For a description of these circumstances, see the section entitled “The Merger Agreement — Termination” beginning on page 109.

In order to complete the merger, ConocoPhillips and Marathon Oil must make certain governmental filings and obtain certain governmental authorizations, and if such filings and authorizations are not made or granted or are granted with conditions to the parties, the closing of the merger may be jeopardized or the anticipated benefits of the merger could be reduced.

The closing of the merger is conditioned upon the expiration or termination of any applicable waiting period, or any extension thereof, under the HSR Act and any applicable waiting period, clearance or

28

affirmative or deemed approval of any governmental entity or other condition with respect to certain non-U.S. antitrust approvals having expired or been terminated, or been obtained or satisfied, as applicable. Although ConocoPhillips and Marathon Oil have agreed in the merger agreement to use their reasonable best efforts to make certain governmental filings or obtain the required governmental authorizations, as the case may be, there can be no assurance that the relevant waiting periods will expire or that the relevant authorizations will be obtained. In addition, the Bundeskartellamt and certain other non-U.S. governmental authorities with or from which these authorizations are required have broad discretion in administering the governing regulations. Adverse developments in ConocoPhillips’ or Marathon Oil’s regulatory standing or any other factors considered by regulators in granting such approvals; governmental, political or community group inquiries, investigations or opposition; or changes in legislation or the political environment generally could affect whether and when required governmental authorizations are granted. As a condition to authorization of the merger, governmental authorities may impose requirements, limitations or costs or place restrictions on the conduct of ConocoPhillips’ business after completion of the merger. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying the closing of the merger or imposing additional material costs on or materially limiting the revenues of the combined company following the merger, or otherwise adversely affecting ConocoPhillips’ businesses and results of operations after completion of the merger. In addition, there can be no assurance that these terms, obligations or restrictions will not result in the delay or abandonment of the merger. For additional information, see the sections entitled “The Merger — Regulatory Approvals” beginning on page 70 and “The Merger Agreement — HSR and Other Regulatory Approvals” beginning on page 99.

ConocoPhillips and Marathon Oil will be subject to business uncertainties while the merger is pending, which could adversely affect their respective businesses.

Uncertainty about the effect of the merger on employees, industry contacts and business partners may have an adverse effect on ConocoPhillips and Marathon Oil. These uncertainties may impair ConocoPhillips’ and Marathon Oil’s ability to attract, retain and motivate key personnel until the merger is completed and for a period of time thereafter and could cause industry contacts, business partners and others that deal with ConocoPhillips and Marathon Oil to seek to change their existing business relationships with ConocoPhillips and Marathon Oil, respectively. Employee retention at Marathon Oil may be particularly challenging during the pendency of the merger, as employees may experience uncertainty about their roles with ConocoPhillips following the merger. In addition, the merger agreement restricts Marathon Oil from entering into certain corporate transactions and taking other specified actions without the consent of ConocoPhillips, and generally requires each party to continue its operations in the ordinary course, until completion of the merger. These restrictions may prevent ConocoPhillips and Marathon Oil from pursuing attractive business opportunities that may arise prior to the completion of the merger. The foregoing may negatively affect the businesses, operations and financial results of each party during the pendency of the merger and may continue to affect the combined company following the completion of the merger. For a description of the restrictive covenants to which ConocoPhillips and Marathon Oil are subject, see the section entitled “The Merger Agreement — Interim Operations of Marathon Oil and ConocoPhillips Pending the Merger” beginning on page 87.

Directors and executive officers of Marathon Oil may have interests in the merger that are different from, or in addition to, the interests of Marathon Oil stockholders.

Directors and executive officers of Marathon Oil may have interests in the merger that are different from, or in addition to, the interests of Marathon Oil stockholders generally. These interests include, among others, the treatment of outstanding equity and equity-based awards pursuant to the merger agreement, potential severance and other benefits upon a qualifying termination in connection with the merger and rights to ongoing indemnification and insurance coverage. These interests are described in more detail in the section entitled “The Merger — Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72. The Marathon Oil board was aware of and carefully considered the interests of its directors and officers, among other matters, in evaluating the terms and structure, and overseeing the negotiation of the merger, in approving the merger agreement and the transactions contemplated thereby, including the merger, and in making its recommendation that Marathon Oil stockholders vote “FOR” the

29

approval of the merger proposal, “FOR” the approval of the non-binding compensation advisory proposal and “FOR” the approval of the adjournment proposal.

The merger may not be accretive, and may be dilutive, to ConocoPhillips’ earnings per share, which may negatively affect the market price of ConocoPhillips common stock.

Because shares of ConocoPhillips common stock will be issued in the merger, it is possible that, although ConocoPhillips currently expects the merger to be accretive to earnings per share, the merger may be dilutive to ConocoPhillips’ earnings per share. This outcome could negatively affect the market price of ConocoPhillips common stock. The issuance of new shares of ConocoPhillips common stock in connection with the merger could have the effect of depressing the market price of ConocoPhillips common stock, through dilution of earnings per share or otherwise. Any dilution of, or delay of any accretion to, ConocoPhillips’ earnings per share could cause the price of shares of ConocoPhillips common stock to decline or increase at a reduced rate.

ConocoPhillips and Marathon Oil will incur significant transaction and merger-related costs in connection with the merger, which may be in excess of those anticipated by ConocoPhillips or Marathon Oil.

Each of ConocoPhillips and Marathon Oil has incurred and expects to continue to incur a number of non-recurring costs associated with negotiating and completing the merger, combining the operations of the two companies and achieving desired synergies. These fees and costs have been, and will continue to be, substantial. The substantial majority of non-recurring expenses will consist of transaction costs related to the merger and include, among others, employee retention costs, fees paid to financial, legal and accounting advisors, severance and benefit costs and filing fees.

ConocoPhillips and Marathon Oil will also incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. ConocoPhillips and Marathon Oil will continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the merger and the integration of the two companies’ businesses. Although ConocoPhillips and Marathon Oil each expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow ConocoPhillips and Marathon Oil to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all. For additional information, see the risk factor entitled “— The integration of Marathon Oil into ConocoPhillips may not be as successful as anticipated” below. The costs described above, as well as other unanticipated costs and expenses, could have a material adverse effect on the financial condition and operating results of ConocoPhillips following the completion of the merger. Many of these costs will be borne by Marathon Oil even if the merger is not completed.

Lawsuits may be filed against Marathon Oil, ConocoPhillips, Merger Sub and the members of the Marathon Oil and ConocoPhillips boards in connection with the merger. An adverse ruling in any such lawsuit could result in an injunction preventing the completion of the merger and/or substantial costs to ConocoPhillips and Marathon Oil.

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements like the merger agreement. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on ConocoPhillips’ and Marathon Oil’s respective liquidity and financial condition.

Although Marathon Oil and ConocoPhillips are not aware of any pending or threatened lawsuits relating to the transactions contemplated by the merger agreement as of the date of this proxy statement/​prospectus, lawsuits arising out of the transactions contemplated by the merger agreement could be filed in the future.

One of the conditions to the closing of the merger is that no injunction by any governmental entity having jurisdiction over ConocoPhillips, Marathon Oil or Merger Sub has been entered and continues to be in effect and no law has been adopted, in either case that prohibits the closing of the merger. Consequently, if a plaintiff is successful in obtaining an injunction prohibiting completion of the merger, that injunction may

30

delay or prevent the merger from being completed within the expected timeframe or at all, which may adversely affect ConocoPhillips’ and Marathon Oil’s respective business, financial position and results of operations. Even if such injunction is eventually lifted and the merger is later completed, the resulting delays and costs incurred may continue to affect the combined company following the completion of the merger.

Additionally, there can be no assurance that any of the defendants will be successful in the outcome any potential lawsuits. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is completed may adversely affect the combined company’s business, financial condition, results of operations and cash flows.

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

Marathon Oil has received an opinion from its financial advisor in connection with the signing of the merger agreement, but has not obtained an updated opinion as of the date of this proxy statement/​prospectus. Changes in the operations and prospects of ConocoPhillips or Marathon Oil, general market and economic conditions and other factors that may be beyond the control of Marathon Oil, and on which Marathon Oil’s financial advisor’s opinion was based, may significantly alter the value of ConocoPhillips or Marathon Oil or the prices of the shares of ConocoPhillips common stock or of the shares of Marathon Oil common stock by the time the merger is completed. The opinion does not speak as of the time the merger will be completed nor as of any date other than the date of the opinion. Because Marathon Oil 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 Marathon Oil board’s recommendation that Marathon Oil stockholders vote “FOR” the approval of the merger proposal, the non-binding compensation advisory proposal and the adjournment proposal, however, is made as of the date of this proxy statement/prospectus.

For a description of the opinion that Marathon Oil received from its financial advisor, see the section entitled “The Merger — Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor” beginning on page 58. A copy of the opinion of Morgan Stanley, Marathon Oil’s financial advisor, is attached as Annex B and is incorporated by reference herein in its entirety.

Completion of the merger may trigger change in control or other provisions in certain agreements to which Marathon Oil is a party.

The completion of the merger may trigger change in control or other provisions in certain agreements to which Marathon Oil is a party. If ConocoPhillips and Marathon Oil 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 ConocoPhillips and Marathon Oil 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 Marathon Oil. Termination of such agreements, payments of fees and other expenses incurred in connection with change of control or other provisions triggered as a result of the merger may negatively affect Marathon Oil’s business, operations and financial results prior to the completion of the merger and many continue to negatively affect the combined company following the completion of the merger.

Shares of ConocoPhillips common stock received by Marathon Oil stockholders as a result of the merger will have different rights from shares of Marathon Oil common stock.

Upon completion of the merger, Marathon Oil stockholders will no longer be stockholders of Marathon Oil, and Marathon Oil stockholders who receive merger consideration will become ConocoPhillips stockholders. There will be important differences between the current rights of Marathon Oil stockholders and the rights to which such stockholders will be entitled as ConocoPhillips stockholders. For a discussion of the different rights associated with shares of ConocoPhillips common stock, see the section entitled “Comparison of Stockholders’ Rights” beginning on page 138.

31

Marathon Oil 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 Delaware law, holders of shares of Marathon Oil common stock will not have rights to an appraisal of the fair value of their shares in connection with the merger.

Marathon Oil may waive one or more of the closing conditions without re-soliciting stockholder approval.

Marathon Oil may determine to waive, in whole or part, one or more of the conditions to closing prior to Marathon Oil being obligated to consummate the merger. Any determination whether to waive any conditions to closing, or to re-solicit stockholder approval to amend or supplement this proxy statement/​prospectus as a result of such a waiver, will be made by Marathon Oil at the time of such waiver based on the facts and circumstances as they exist at that time.

The combined company’s debt may limit its financial flexibility.

As of March 31, 2024, ConocoPhillips had approximately $18.4 billion of outstanding indebtedness, consisting of amounts outstanding under its unsubordinated notes and commercial paper program supported by its existing credit facility. As of March 31, 2024, Marathon Oil had approximately $5.46 billion of outstanding indebtedness, consisting of amounts outstanding under its (i) 4.400% senior notes due 2027, 5.300% senior notes due 2029, 6.800% senior notes due 2032, 5.700% senior notes due 2034, 6.600% senior notes due 2037 and 5.200% senior notes due 2045 (which we refer to collectively as the “Marathon Oil Notes”), (ii) commercial paper program, (iii) series 2017 revenue refunding bonds issued by the Parish of St. John the Baptist, State of Louisiana, and in connection with which Marathon Oil has agreed to make payments sufficient to pay the principal and interest thereon (which we refer to as the “Marathon Municipal Bonds”) and (iv) revolving credit facility. ConocoPhillips expects Marathon Oil’s commercial paper program and revolving credit facility to be terminated in connection with the consummation of the merger. ConocoPhillips expects that the Marathon Oil Notes and the Marathon Municipal Bonds will remain outstanding or that it will commence exchange offers and consent solicitations in connection therewith. For a more detailed discussion, see “The Merger Agreement — Treatment of Indebtedness.”

ConocoPhillips’ pro forma indebtedness as of March 31, 2024, assuming consummation of the merger had occurred on such date and the assumption of the Marathon Oil Notes, the Marathon Municipal Bonds remaining outstanding and the extinguishment of the Marathon Oil revolving credit facility and commercial paper program in connection therewith, is approximately $23.4 billion, representing an increase in comparison to ConocoPhillips’ indebtedness on a recent historical basis. Any increase in ConocoPhillips’ indebtedness could have adverse effects on its financial condition and results of operations, including:

•

imposing additional cash requirements on ConocoPhillips in order to support interest payments, which reduces the amount ConocoPhillips has available to fund its operations and other business activities;

•

increasing the risk that ConocoPhillips may default on its debt obligations;

•

increasing ConocoPhillips’ vulnerability to adverse changes in general economic and industry conditions, economic downturns and adverse developments in its business;

•

limiting ConocoPhillips’ ability to sell assets, engage in strategic transactions or obtain additional financing for working capital, capital expenditures, general corporate and other purposes;

•

limiting ConocoPhillips’ flexibility in planning for or reacting to changes in its business and the industry in which it operates; and

•

increasing ConocoPhillips’ exposure to a rise in interest rates, which will generate greater interest expense to the extent ConocoPhillips does not have applicable interest rate fluctuation hedges.

The unaudited pro forma combined financial information included in this proxy statement/prospectus is presented for illustrative purposes only and does not represent the actual financial position or results of operations of the combined company following the completion of the merger. Future results of ConocoPhillips or Marathon Oil may differ, possibly materially, from the unaudited pro forma combined financial information presented in this proxy statement/prospectus.

The unaudited pro forma combined financial statements contained in this proxy statement/prospectus is presented for illustrative purposes only, contains a variety of adjustments, assumptions and preliminary estimates and does not represent the actual financial position or results of operations of ConocoPhillips and Marathon Oil prior to the merger or that of the combined company following the merger for several reasons. Specifically, the unaudited pro forma combined financial statements do not reflect the effect of any potential divestitures that may occur prior to or subsequent to the completion of the merger, integration costs or any changes in ConocoPhillips’ debt to capitalization ratio following the completion of the merger. For additional information, see the section entitled “Unaudited Pro Forma Combined Financial Statements” beginning on page 116. In addition, the merger and post-merger integration process may give rise to unexpected liabilities and costs, including costs associated with the defense and resolution of transaction-related litigation or other claims. Unexpected delays in completing the merger or in connection with the post-merger integration process may significantly increase the related costs and expenses incurred by ConocoPhillips. The actual financial positions and results of operations of ConocoPhillips and Marathon Oil prior to the merger and that of the combined company following the merger may be different, possibly materially, from the unaudited pro forma combined financial statements included in this proxy statement/​prospectus. In addition, the assumptions used in preparing the unaudited pro forma combined financial statements included in this proxy statement/prospectus may not prove to be accurate and may be affected by other factors. Any significant changes in the market price of ConocoPhillips common stock may cause a significant change in the purchase price used for ConocoPhillips’ accounting purposes and the unaudited pro forma financial statements contained in this proxy statement/prospectus.

The financial forecasts are based on various assumptions that may not be realized.

The financial estimates set forth in the forecasts included under the section “The Merger — Marathon Oil Unaudited Forecasted Financial Information” beginning on page 66 were based on assumptions of, and information available to, Marathon Oil’s management, when prepared, and these estimates and assumptions are subject to uncertainties, many of which are beyond Marathon Oil’s control and may not be realized. Many factors mentioned in this proxy statement/prospectus, including the risks outlined in this “Risk Factors” section and the events or circumstances described under “Cautionary Statement Regarding Forward-Looking Statements,” will be important in determining the combined company’s future results. As a result of these contingencies, actual future results may vary materially from Marathon Oil’s estimates. In view of these uncertainties, the inclusion of financial estimates in this proxy statement/prospectus is not and should not be viewed as a representation that the forecasted results will necessarily reflect actual future results.

Marathon Oil’s financial estimates were 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. Further, any forward-looking statement speaks only as of the date on which it is made, and Marathon Oil does not undertake any obligation, other than as required by applicable law, to update the financial estimates herein to reflect events or circumstances after the date those financial estimates were prepared or to reflect the occurrence of anticipated or unanticipated events or circumstances.

The financial estimates of Marathon Oil included in this proxy statement/prospectus have been prepared by, and are the responsibility of, Marathon Oil. Moreover, neither Marathon Oil’s independent accountants nor any other independent accountants, have audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying financial estimates and, accordingly, independent accountants do not express an opinion or any other form of assurance with respect thereto. The reports of such independent accountants incorporated by reference herein relate to the previously issued financial statements of the entities named in those reports. Such reports do not extend to the financial estimates and should not be read to do so. For more information, see the section entitled “The Merger — Marathon Oil Unaudited Forecasted Financial Information” beginning on page 66.

The integration of Marathon Oil into ConocoPhillips may not be as successful as anticipated.

The merger involves numerous operational, strategic, financial, accounting, legal, tax and other risks, potential liabilities associated with the acquired businesses, and uncertainties related to design, operation and integration of Marathon Oil’s internal control over financial reporting. Difficulties in integrating Marathon Oil into ConocoPhillips may result in Marathon Oil performing differently than expected, in operational challenges or in the failure to realize anticipated expense-related efficiencies. ConocoPhillips’ and Marathon Oil’s existing businesses could also be negatively impacted by the merger. Potential difficulties that may be encountered in the integration process include, among other factors:

•

the inability to successfully integrate the businesses of Marathon Oil into ConocoPhillips in a manner that permits ConocoPhillips to achieve the full revenue and cost savings anticipated from the merger;

•

complexities associated with managing the larger, more complex, integrated business;

•

not realizing anticipated operating synergies;

•

integrating personnel from the two companies and the loss of key employees;

•

potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the merger;

•

integrating relationships with industry contacts and business partners;

•

performance shortfalls at one or both of the companies as a result of the diversion of management’s attention caused by completing the merger and integrating Marathon Oil’s operations into ConocoPhillips; and

•

the disruption of, or the loss of momentum in, each company’s ongoing business or inconsistencies in standards, controls, procedures and policies.

The combined company’s results may suffer if it does not effectively manage its expanded operations following the merger.

Following completion of the merger, the combined company’s success will depend, in part, on ConocoPhillips’ ability to manage the expansion resulting from the merger, which poses numerous risks and uncertainties, including the need to integrate the operations and business of Marathon Oil into its existing business in an efficient and timely manner, to combine systems and management controls and to integrate relationships with industry contacts and business partners.

Even if ConocoPhillips and Marathon Oil complete the merger, the combined company may fail to realize all of the anticipated benefits of the merger.

The success of the merger will depend, in part, on the combined company’s ability to realize the anticipated benefits and cost savings from combining ConocoPhillips’ and Marathon Oil’s businesses, including operational and other synergies. The anticipated benefits and cost savings of the merger may not be realized fully or at all, may take longer to realize than expected or could have other adverse effects that ConocoPhillips and Marathon Oil do not currently foresee. Some of the assumptions that ConocoPhillips has made, such as the achievement of operating synergies, may not be realized. The integration process may, for each of ConocoPhillips and Marathon Oil, result in the loss of key employees, the disruption of ongoing businesses or inconsistencies in standards, controls, procedures and policies. There could be potential unknown liabilities and unforeseen expenses associated with the merger that were not discovered in the course of performing due diligence. The foregoing may negatively affect the combined company’s ongoing business, operations and financial results following the completion of the merger.

Uncertainties associated with the merger may cause a loss of management personnel and other key employees, which could adversely affect the future business and operations of the combined company.

ConocoPhillips and Marathon Oil are dependent on the experience and industry knowledge of their officers and other key employees to execute their business plans. Each company’s success until the merger

34

and the combined company’s success after the merger will depend in part upon the ability of ConocoPhillips and Marathon Oil to retain key management personnel and other key employees. Current and prospective employees of ConocoPhillips and Marathon Oil may experience uncertainty about their roles within the combined company following the merger, which may have an adverse effect on the ability of each of ConocoPhillips and Marathon Oil to attract or retain key management and other key personnel. Accordingly, no assurance can be given that the combined company will be able to attract or retain key management personnel and other key employees of ConocoPhillips and Marathon Oil to the same extent that ConocoPhillips and Marathon Oil have previously been able to attract or retain their own employees.

The market price of ConocoPhillips common stock may decline in the future as a result of the sale of shares of ConocoPhillips common stock held by former Marathon Oil stockholders or current ConocoPhillips stockholders.

Following their receipt of shares of ConocoPhillips common stock as merger consideration in the merger, former Marathon Oil stockholders may seek to sell the shares of ConocoPhillips common stock delivered to them, and the merger agreement contains no restriction on the ability of former Marathon Oil stockholders to sell such shares of ConocoPhillips common stock following completion of the merger. Other ConocoPhillips stockholders may also seek to sell shares of ConocoPhillips common stock held by them following, or in anticipation of, completion of the merger. These sales (or the perception that these sales may occur), coupled with the increase in the outstanding number of shares of ConocoPhillips common stock, may affect the market for, and the market price of, ConocoPhillips common stock in an adverse manner.

The combined company may record goodwill and other intangible assets that could become impaired and result in material non-cash charges to the results of operations of the combined company in the future.

The merger will be accounted for as an acquisition by ConocoPhillips in accordance with accounting principles generally accepted in the United States (which we refer to as “GAAP”). Under the acquisition method of accounting, the assets and liabilities of Marathon Oil and its subsidiaries will be recorded, as of completion, at their respective fair values and added to those of ConocoPhillips. The reported financial condition and results of operations of ConocoPhillips for periods after completion of the merger will reflect Marathon Oil balances and results after completion of the merger but will not be restated retroactively to reflect the historical financial position or results of operations of Marathon Oil and its subsidiaries for periods prior to the merger. For additional information, see the section entitled “Unaudited Pro Forma Combined Financial Statements” beginning on page 116.

Under the acquisition method of accounting, the total purchase price will be allocated to Marathon Oil’s tangible assets and liabilities and identifiable intangible assets based on their fair values as of the date of completion of the merger. The excess of the purchase price over those fair values will be recorded as goodwill. ConocoPhillips and Marathon Oil expect that the merger may result in the creation of goodwill based upon the application of the acquisition method of accounting. To the extent goodwill or intangibles are recorded and the values become impaired, the combined company may be required to recognize material non-cash charges relating to such impairment. The combined company’s operating results may be significantly impacted from both the impairment and the underlying trends in the business that triggered the impairment.

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

To mitigate its exposure to changes in commodity prices, Marathon Oil hedges oil, natural gas and NGL prices from time to time, primarily through the use of certain derivative instruments. If ConocoPhillips assumes existing Marathon Oil hedges or hedges that Marathon Oil enters into prior to the completion of the merger, ConocoPhillips will bear the economic impact of all of Marathon Oil’s hedges following the completion of the merger. Actual crude oil, natural gas and NGL prices may differ from the combined company’s expectations and, as a result, such hedges may or may not have a negative impact on ConocoPhillips’ business.

35

Risks Relating to ConocoPhillips’ Business

Because Marathon Oil stockholders will become ConocoPhillips stockholders following the completion of the merger, they should carefully read and consider the risk factors specific to ConocoPhillips, as these factors will affect the combined company after the completion of the merger. These risks are described in Part I, Item 1A of ConocoPhillips’ Annual Report on Form 10-K for the fiscal year ended December 31, 2023, in Part II, Item 1A of ConocoPhillips’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 and in other documents that are incorporated by reference herein. For the location of information incorporated by reference in this proxy statement/prospectus, see the section entitled “Where You Can Find More Information” beginning on page 157.

Risks Relating to Marathon Oil’s Business

You should read and consider the risk factors specific to Marathon Oil, as these factors could continue to affect the combined company after the completion of the merger. These risks are described in Part I, Item 1A of Marathon Oil’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, in Part II, Item 1A of Marathon Oil’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 and in other documents that are incorporated by reference herein. For the location of information incorporated by reference in this proxy statement/prospectus, see the section entitled “Where You Can Find More Information” beginning on page 157.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement/prospectus, and the documents to which Marathon Oil and ConocoPhillips refer you in this proxy statement/prospectus, include certain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements, other than statements of historical fact, included in this proxy statement/prospectus that address activities, events or developments that Marathon Oil or ConocoPhillips expects, believes or anticipates will or may occur in the future are forward-looking statements. These may include, among others, statements relating to future events and anticipated results of operations and business strategies, the merger, including the anticipated benefits of the merger, the anticipated impact of the merger on the combined company’s business and future financial and operating results, the expected amount and timing of synergies from the merger, the anticipated closing date for merger and aspects of operations or operating.

However, the absence of these words does not mean that the statements are not forward-looking. Where, in any forward-looking statement, Marathon Oil or ConocoPhillips expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to be reasonable at the time such forward-looking statement is made. However, these statements are not guarantees of future performance and involve certain risks, uncertainties and other factors beyond Marathon Oil’s and ConocoPhillips’ control. Therefore, actual outcomes and results may differ materially from what is expressed or forecast in any forward-looking statements. The following important factors and uncertainties, among others, could cause actual results or events to differ materially from those included in this proxy statement/prospectus:

SPECIAL MEETING OF MARATHON OIL STOCKHOLDERS

Date, Time and Place

The special meeting will be held on August 29, 2024, at 8:00 a.m., Central Time, in the Level 6 Auditorium of One MRO, located at 990 Town & Country Blvd in Houston, Texas 77024. This proxy statement/​prospectus is first being furnished to the Marathon Oil stockholders on or about July 29, 2024.

Purpose of the Special Meeting

The purpose of the special meeting is to consider and vote on:

•

the merger proposal;

•

the non-binding compensation advisory proposal; and

•

the adjournment proposal.

Marathon Oil will transact no other business at the special meeting.

Recommendation of the Marathon Oil Board of Directors

The Marathon Oil board unanimously recommends that Marathon Oil stockholders vote:

•

“FOR” the merger proposal;

•

“FOR” the non-binding compensation advisory proposal; and

•

“FOR” the adjournment proposal.

For additional information on the recommendation of the Marathon Oil board, see the section entitled “The Merger — Recommendation of the Marathon Oil Board of Directors and Reasons for the Merger” beginning on page 54.

Record Date and Outstanding Shares of Marathon Oil Common Stock

Only holders of record of issued and outstanding shares of Marathon Oil common stock as of the close of business on July 26, 2024, the record date for the special meeting, are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of the special meeting.

As of the record date, there were 559,383,423 shares of Marathon Oil common stock issued and outstanding and entitled to vote at the special meeting. You may cast one vote for each share of Marathon Oil common stock that you held as of the close of business on the record date.

A complete list of Marathon Oil stockholders entitled to vote at the special meeting will be available for inspection at Marathon Oil’s principal place of business during regular business hours for a period of no less than 10 days before the special meeting at 990 Town and Country Boulevard Houston, Texas 77024.

Quorum; Abstentions and Broker Non-Votes

A quorum of Marathon Oil stockholders is necessary to hold a valid meeting. The presence at the special meeting, in person or by proxy, of the holders of at least one-third of the outstanding shares of Marathon Oil common stock entitled to vote at the special meeting constitutes a quorum. If you submit a properly executed proxy card, even if you do not vote for any of the proposals or vote to “ABSTAIN” in respect of each proposal, your shares of Marathon Oil common stock will be counted for purposes of calculating whether a quorum is present for the transaction of business at the special meeting.

Marathon Oil common stock held in “street name” with respect to which the beneficial owner fails to give voting instructions to the broker, bank or other nominee, and Marathon Oil common stock with respect to which the beneficial owner otherwise fails to vote, will not be considered present and entitled to vote at the special meeting for the purpose of determining the presence of a quorum.

41

A broker non-vote will result if your broker, bank or other nominee returns a proxy but does not provide instruction as to how shares should be voted on a particular matter. Under the current rules of the NYSE, brokers, banks or other nominees do not have discretionary authority to vote on the merger proposal, the non-binding compensation advisory proposal or the adjournment proposal. Because the only proposals for consideration at the special meeting are non-discretionary proposals, it is not expected that there will be any broker non-votes at the special meeting. However, if there are any broker non-votes, the shares will not be considered present and entitled to vote at the special meeting for the purpose of determining the presence of a quorum.

Executed but unvoted proxies will be voted in accordance with the recommendations of the Marathon Oil board (i.e., “FOR” all of the proposals).

Required Vote

Approval of the merger proposal requires the affirmative vote of a majority of the outstanding shares of Marathon Oil common stock entitled to vote on the proposal. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” the proposal. Failure to vote on the merger proposal will have the same effect as a vote “AGAINST” the merger proposal.

Approval of the non-binding compensation advisory proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, assuming a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote.

Approval of the adjournment proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, regardless of whether a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote.

The merger proposal, the non-binding compensation advisory proposal and the adjournment proposal are described in the section entitled “Marathon Oil Proposals” beginning on page 46.

The adjourned meeting may take place without further notice other than by an announcement made at the special meeting. In a subsequent reconvening of the special meeting, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Regardless of the results of voting for the adjournment proposal, the Marathon Oil bylaws allow the chair of the special meeting to adjourn the special meeting at his or her discretion, subject to the terms of the merger agreement.

Under the terms of the merger agreement, Marathon Oil may not, without the prior written consent of ConocoPhillips (such consent not to be unreasonably withheld, conditioned or delayed), adjourn, postpone or otherwise delay the special meeting; provided that Marathon Oil may, notwithstanding the foregoing, without the prior written consent of ConocoPhillips, and must if requested by ConocoPhillips, adjourn or postpone the special meeting (i) if, after consultation with ConocoPhillips, Marathon Oil believes in good faith that such adjournment or postponement is reasonably necessary to allow reasonable additional time to (A) solicit additional proxies in favor of the merger proposal or (B) distribute any supplement or amendment to this proxy statement/prospectus, the distribution of which the Marathon Oil 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, and Marathon Oil must use its reasonable best efforts to obtain such a quorum as promptly as practicable. Notwithstanding the foregoing, (i) Marathon Oil may not, without the prior written consent of ConocoPhillips (such consent not to be unreasonably withheld, conditioned or delayed) postpone or adjourn the special meeting (A) more than a total of three times pursuant to the foregoing or (B) for a period exceeding 10 business days in the aggregate pursuant to the foregoing; and (ii) if the special meeting is postponed or adjourned, Marathon Oil must reconvene the special meeting at the earliest practicable date on which it reasonably expects to have sufficient affirmative votes for approval of the merger proposal; and provided, further that the special meeting may not be adjourned or postponed to a date on or after three business prior to the end date.

Proxy Solicitation Costs

The enclosed proxy card is being solicited by Marathon Oil and the Marathon Oil board. In addition to solicitation by mail, Marathon Oil’s directors, officers and employees may solicit proxies in person, by phone or by electronic means. These persons will not be specifically compensated for conducting such solicitation.

Marathon Oil has retained the Marathon Oil proxy solicitor to assist in the solicitation process. Marathon Oil will pay the Marathon Oil proxy solicitor a fee of $50,000, plus reasonable out-of-pocket expenses and fees for any additional services. Marathon Oil also has agreed to indemnify the Marathon Oil proxy solicitor against various liabilities and expenses that relate to or arise out of its solicitation of proxies (subject to certain exceptions).

Marathon Oil will ask brokers, banks and other nominees to forward the proxy solicitation materials to the beneficial owners of shares of Marathon Oil common stock held of record by such nominee holders. Marathon Oil will reimburse these nominee holders for their customary clerical and mailing expenses incurred in forwarding the proxy solicitation materials to the beneficial owners.

No Appraisal Rights

Because shares of Marathon Oil common stock are listed on the NYSE and holders of shares of Marathon Oil common stock are not required to receive consideration other than shares of ConocoPhillips common stock, which are listed on the NYSE, and cash in lieu of fractional shares in the merger, holders of shares of Marathon Oil common stock are not entitled to exercise appraisal rights under Delaware law in connection with the merger.

MARATHON OIL PROPOSALS

Merger Proposal

It is a condition to the completion of the merger that Marathon Oil stockholders approve the merger proposal. In the merger, each Marathon Oil stockholder will receive, for each eligible share of Marathon Oil common stock that is issued and outstanding as of immediately prior to the effective time of the merger, the merger consideration of 0.255 shares of ConocoPhillips common stock, further described in the sections entitled “The Merger — Merger Consideration” beginning on page 48 and “The Merger Agreement — Effect of the Merger on Capital Stock; Merger Consideration” beginning on page 80.

The approval by such stockholders of this proposal is required by Section 251 of the DGCL and is a condition to the completion of the merger.

Approval of the merger proposal requires the affirmative vote of a majority of the outstanding shares of Marathon Oil common stock entitled to vote on the proposal. Abstentions and broker non-votes will have the same effect as a vote “AGAINST” the merger proposal. Failure to vote on the merger proposal will have the same effect as a vote “AGAINST” the merger proposal.

The Marathon Oil board unanimously recommends a vote “FOR” the merger proposal.

Non-Binding Compensation Advisory Proposal

As required by Section 14A of the Exchange Act and the applicable SEC rules issued thereunder, which were enacted pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, Marathon Oil is required to provide its stockholders the opportunity to vote to approve, on a non-binding, advisory basis, certain compensation that may be paid or become payable to Marathon Oil’s named executive officers that is based on or otherwise relates to the merger, as described in the section entitled “The Merger — Merger-Related Compensation” beginning on page 75. Accordingly, Marathon Oil stockholders are being provided the opportunity to cast an advisory vote on such payments.

As an advisory vote, this proposal is not binding upon Marathon Oil or the Marathon Oil board or ConocoPhillips or the ConocoPhillips board, and approval of this proposal is not a condition to completion of the merger and is a vote separate and apart from the merger proposal. Accordingly, you may vote to approve the merger proposal and vote not to approve the non-binding compensation advisory proposal and vice versa. Because the merger-related executive compensation to be paid in connection with the merger is based on the terms of the merger agreement as well as the contractual arrangements with Marathon Oil’s named executive officers, such compensation will be payable, regardless of the outcome of this advisory vote, if the merger proposal is approved (subject only to the contractual conditions applicable thereto). However, Marathon Oil seeks the support of its stockholders and believes that stockholder support is appropriate as the executive compensation programs are designed to incentivize executives to successfully execute a transaction such as that contemplated by the merger proposal from its early stages until consummation. Accordingly, holders of shares of Marathon Oil common stock are being asked to vote on the following resolution:

RESOLVED, that the stockholders of Marathon Oil Corporation approve, on an advisory, non-binding basis, certain compensation that may be paid or become payable to the named executive officers of Marathon Oil Corporation that is based on or otherwise relates to the merger, as disclosed pursuant to Item 402(t) of Regulation S-K under the heading “The Merger — Merger-Related Compensation.”

Approval of the non-binding compensation advisory proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, assuming a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote.

The Marathon Oil board unanimously recommends a vote “FOR” the non-binding compensation advisory proposal.

46

Adjournment Proposal

Marathon Oil stockholders may be asked to vote to approve the adjournment of the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes cast at the special meeting to approve the merger proposal.

The adjourned meeting may take place without further notice other than by an announcement made at the special meeting. In a subsequent reconvening of the special meeting, all proxies will be voted in the same manner as the manner in which such proxies would have been voted at the original convening of the special meeting, except for any proxies that have been validly revoked or withdrawn prior to the subsequent meeting.

Approval of the adjournment proposal requires the affirmative vote of a majority of the shares of Marathon Oil common stock present in person or represented by proxy at the special meeting and entitled to vote on the proposal, regardless of whether a quorum is present. Abstentions will have the same effect as a vote “AGAINST” the proposal, and broker non-votes and failure to vote will have no effect on the outcome of the vote.

The Marathon Oil board unanimously recommends a vote “FOR” the adjournment proposal.

Regardless of the results of voting for the adjournment proposal, the Marathon Oil bylaws allow the chair of the special meeting to adjourn the special meeting at his or her discretion, subject to the terms of the merger agreement.

47

THE MERGER

This discussion of the merger is qualified in its entirety by reference to the merger agreement, which is attached to this proxy statement/prospectus as Annex A and incorporated by reference herein in its entirety. You should read the entire merger agreement carefully as it is the legal document that governs the merger.

Transaction Structure

At the effective time of the merger, Merger Sub will merge with and into Marathon Oil. As a result of the merger, the separate corporate existence of Merger Sub will cease, and Marathon Oil will continue as the surviving corporation in the merger and as a wholly owned subsidiary of ConocoPhillips.

Merger Consideration

As a result of the merger, each eligible share of Marathon Oil common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive, without interest, 0.255 shares of ConocoPhillips common stock (i.e., the merger consideration).

Marathon Oil stockholders will not be entitled to receive any fractional shares of ConocoPhillips common stock in the merger, and no Marathon Oil stockholders will be entitled to dividends, voting rights or any other rights in respect of any fractional shares of ConocoPhillips common stock. Marathon Oil stockholders that would have otherwise been entitled to receive a fractional share of ConocoPhillips common stock will instead be entitled to receive, in lieu of fractional shares, an amount in cash, without interest, equal to the product of the volume weighted average price of ConocoPhillips common stock for the five consecutive trading days ending two trading days prior to the closing date as reported by Bloomberg, L.P. multiplied by the fraction of a share of ConocoPhillips common stock to which the holder would otherwise be entitled.

Background of the Merger

The terms of the merger agreement are the result of arm’s-length negotiations between representatives of ConocoPhillips and Marathon Oil. The following is a summary of the events leading up to the signing of the merger agreement and the key meetings, negotiations and discussions by and between ConocoPhillips and Marathon Oil and their respective advisors that preceded the public announcement of the merger. However, this summary does not purport to catalog every conversation or interaction among the representatives of ConocoPhillips, Marathon Oil and other parties.

The Marathon Oil board, in the ordinary course and consistent with its fiduciary duties, along with the Marathon Oil management team, continually evaluates Marathon Oil’s operations and future business prospects and its short- and long-term performance with a focus on enhancing Marathon Oil’s scale, durability and resilience and an objective of responsibly delivering leading cash returns to stockholders that are sustainable and resilient through all commodity price cycles. In connection with such ongoing evaluation, the Marathon Oil board and management team also review and assess potential strategic alternatives available to Marathon Oil, including merger and acquisition transactions and asset acquisitions and dispositions.

During the course of its evaluations, the Marathon Oil board considered whether various strategic actions, including business combination transactions, would be in the best interests of Marathon Oil and would enhance value for Marathon Oil stockholders. The Marathon Oil board utilized various metrics to evaluate potential opportunities, including relative valuation, financial accretion, balance sheet strength, durability of resource life, scale and industrial logic, and other counterparty specific metrics (including, but not limited to, an alignment on return of cash to shareholder models, portfolio diversity, production mix and execution excellence). From time to time, senior executives of Marathon Oil have had informal and preliminary conversations about potential strategic transaction opportunities with senior executives of other companies and have updated the Marathon Oil board regarding these interactions during regularly scheduled and special meetings of the Marathon Oil board. While the regularly scheduled meetings of the Marathon Oil board often included discussion of strategic alternatives, there is a particular focus during the annual May board meetings with respect to the evaluation of potential strategic transactions available to Marathon Oil that could improve the standalone Marathon Oil business case.

48

In March 2023, Mr. Lee Tillman, Chairman, President and Chief Executive Officer of Marathon Oil, met with the chief executive officer of a publicly traded exploration and production (which we refer to as “E&P”) company (which we refer to as “Party A”) in the ordinary course and discussed, among other topics, their perspectives on developments in the oil and gas industry. Later that same month, the chief executive officer of Party A contacted Mr. Tillman to express Party A’s interest in a potential strategic transaction with Marathon Oil. Over the following several weeks, Mr. Tillman and the chief executive officer of Party A discussed from time to time the perceived merits and risks of a combination, including industrial logic, investor relevance and synergies, as well as mutual financial and legal due diligence needs and the necessity of engaging advisors.

On April 26, 2023, at a regularly scheduled meeting of the Marathon Oil board, Mr. Tillman provided an update on high-level discussions recently held with the chief executive officer of Party A, noting that neither party solicited a proposal for a business combination but that each party expressed interest in continuing the exploratory dialogue.

On April 27, 2023, in connection with Marathon Oil’s consideration of potential strategic alternatives, Marathon Oil contacted Morgan Stanley to act as its lead financial advisor based on its experience and qualifications in M&A transactions. Marathon Oil and Morgan Stanley formally executed an indemnity agreement on May 9, 2023 and, on May 28, 2024, an engagement letter.

On June 15, 2023, Party A submitted a non-binding indication of interest to acquire Marathon Oil in an all-stock transaction in exchange for shares of Party A’s common stock. Party A did not propose a specific exchange ratio, but the non-binding indication of interest referred to providing Marathon Oil stockholders a change of control premium in the transaction.

On June 22, 2023, Marathon Oil and Party A entered into a mutual confidentiality agreement that contained a customary mutual “standstill” provision, a fallaway provision and a modified “don’t ask, don’t waive” provision that did not restrict the ability of either party to make a private proposal regarding a business combination to the board of directors of the other party. Following the execution of the confidentiality agreement, Marathon Oil and Party A commenced the exchange of financial and operational due diligence materials.

In June and July 2023, members of Marathon Oil management continued to update the Marathon Oil board regarding discussions with Party A, including with respect to the exchange of each party’s legal and financial due diligence information.

On July 19, 2023, Party A submitted a non-binding indication of interest to acquire all of Marathon Oil’s outstanding stock in exchange for a number of shares of Party A’s common stock that represented an 11% premium to Marathon Oil’s then 10-day volume weighted average share price. The proposal did not address any governance matters with respect to the proposed combined company.

After several meetings of the Marathon Oil board and discussions between Marathon Oil’s and Party A’s representatives and after Party A announced its second quarter 2023 results, Marathon Oil determined to terminate discussions due to failure to reach agreement on material terms of a proposed transaction. The Marathon Oil board did not view the offered premium as compelling and Party A’s equity performance relative to Marathon Oil had declined further impacting the premium implied by Party A’s July 19 proposal.

On August 17, 2023, a member of the senior executive management team of another publicly traded E&P company (which we refer to as “Party B”) contacted Mr. Pat Wagner, Executive Vice President of Corporate Development and Strategy for Marathon Oil, to express Party B’s interest in a potential strategic transaction with Marathon Oil. Over the following three months, Messrs. Wagner and Tillman met several times with members of Party B’s executive management team to discuss the perceived merits and risks of a potential merger of equals combination and the logistics and planning necessary to advance discussions. No specific terms of a potential transaction were discussed at any meeting, except to note that certain key issues would need to be determined in order to meaningfully advance discussions.

On December 1, 2023, Marathon Oil and Party B entered into a mutual confidentiality agreement that contained a customary mutual “standstill” provision, a fallaway provision and a modified “don’t ask, don’t waive” provision that did not restrict the ability of either party to make a private proposal regarding a business

49

combination to the board of directors of the other party. Marathon Oil and Party B commenced the exchange of financial and operational due diligence materials.

After several meetings of the Marathon Oil board and discussions between Marathon Oil’s and Party B’s representatives, including mutual management presentations, the chief executive officer of Party B contacted Mr. Tillman to inform him that Party B was terminating discussions regarding a potential transaction between Party B and Marathon Oil.

In the first quarter of 2024, Marathon Oil continued to evaluate strategic alternatives reasonably available to it as part of the normal course of business, including the potential bolt-on acquisition of a publicly traded E&P company and other strategic transactions to achieve scale, durability and resilience. The Marathon Oil senior executives continued to provide updates to the Marathon Oil board at its regularly scheduled and special meetings. From time to time, representatives of Party B continued to express interest to representatives of Marathon Oil in a potential strategic transaction between Marathon Oil and Party B but did not provide any specific transaction terms.

On April 8, 2024, at Party B’s request, the chief executive officer of Party B and Mr. Tillman met to discuss Party B’s continued interest in a potential strategic transaction. Mr. Tillman indicated that, based on the considerable amount of time their respective organizations had devoted to considering a potential transaction in 2023, he anticipated the Marathon Oil board would require a written indication of interest with clear transaction terms in order to proceed to re-engage in discussions regarding a transaction. Mr. Tillman also noted the challenges and risks associated with Party B’s current production mix. Mr. Tillman and Party B’s chief executive officer did not further discuss the terms of any potential transaction at the meeting.

On April 10, 2024, at Party A’s request, the chief executive officer of Party A and Mr. Tillman met and the chief executive officer of Party A indicated that Party A would be interested in re-engaging in discussions regarding a potential transaction after both Marathon Oil and Party A announced their respective first quarter earnings the following month. Mr. Tillman indicated that, based on the considerable amount of time their respective organizations had devoted to considering a potential transaction in 2023, he anticipated the Marathon Oil board would require a written indication of interest with clear transaction terms in order to proceed to re-engage in discussions regarding a transaction. No further discussions regarding the terms of any potential transaction were had at the meeting.

On April 25, 2024, Mr. Andrew Hastings, VP, Corporate Acquisitions & Divestitures at ConocoPhillips, contacted Mr. Wagner to express ConocoPhillips’ interest in acquiring Marathon Oil should Marathon Oil determine to engage in a potential strategic transaction.

On April 29, 2024, a representative of Party B contacted Mr. Wagner to express interest in re-engaging in discussions regarding a potential strategic transaction, but no immediate actions were taken.

On May 6, 2024, Mr. Wagner contacted a representative of Party B and stated that, if Party B were still interested in engaging, time would be of the essence due to other parties that were interested in a strategic transaction with Marathon Oil.

On May 7, 2024, Mr. Wagner contacted Mr. Hastings to state that Marathon Oil had interest from other parties and Messrs. Wagner and Hastings agreed to arrange for a meeting between chief executive officers of each party.

On May 8, 2024, Mr. Tillman and Mr. Ryan Lance, Chairman and Chief Executive Officer of ConocoPhillips, corresponded to arrange for an in-person meeting and Mr. Tillman informed Mr. Lance that Marathon Oil would need a written indication of interest in advance of the Marathon Oil board’s regularly scheduled meeting set for May 21 and 22, 2024.

On May 9, 2024, Messrs. Tillman and Lance met to discuss the perceived merits and risks of a potential acquisition of Marathon Oil by ConocoPhillips, including the potential benefits to scale, durability and resilience resulting from combining the two companies, which stockholders of Marathon Oil would benefit from as shareholders of the combined company.

50

On May 9, 2024, a representative of Party A delivered to representatives of Marathon Oil a non-binding indication of interest pursuant to which Party A would acquire Marathon Oil in an all-stock transaction at a fixed exchange ratio, representing a premium of 16% to Marathon Oil’s share price at the close of market on May 8, 2024 (the “Party A proposal”), an improvement to Party A’s July 19, 2023 proposal. The proposal included the willingness to nominate two Marathon Oil directors to the Party A board, with Party A’s chairman and chief executive officer remaining in their respective roles in the combined company.

Also on May 9, 2024, a representative of Party B delivered to representatives of Marathon Oil a non-binding indication of interest pursuant to which Party B would acquire Marathon Oil in an all-stock, merger of equals transaction at a fixed exchange ratio, representing a premium of 5% to Marathon Oil’s share price at the close of market on May 8, 2024 (the “Party B proposal”). Party B proposed a shared governance model with a combined company board of directors with 12 total directors, seven named by Party B and five named by Marathon Oil and with the lead independent director nominated by Marathon Oil. Party B also proposed a senior leadership team that would include two executive vice presidents from Marathon Oil.

On May 10, 2024, ConocoPhillips and Marathon Oil entered into a mutual confidentiality agreement that contained a customary mutual “standstill” provision, a fallaway provision and a modified “don’t ask, don’t waive” provision that did not restrict the ability of either party to make a private proposal regarding a business combination to board of directors of the other party. ConocoPhillips and Marathon Oil commenced the exchange of financial and operational due diligence materials.

On May 13, 2024, the Party A proposal, the Party B proposal and the expression of interest from ConocoPhillips were disclosed to the Marathon Oil board.

On May 17, 2024, Mr. Tillman separately contacted the chief executive officers of each of Party A and Party B to affirm that their respective proposals were under careful review and noted that the Marathon Oil board would consider their proposal at its next regularly scheduled board meeting the following week. Later that same day, representatives of Marathon Oil convened via telephone with representatives of Party A to discuss the exchange of financial due diligence materials and with representatives of Party B to reiterate the fact that there were other potential interested parties and that Party B should consider submitting an enhanced proposal.

Also on May 17, 2024, a representative of ConocoPhillips delivered to representatives of Marathon Oil a written non-binding indication of interest (which we refer to as the “ConocoPhillips proposal”) pursuant to which ConocoPhillips would acquire Marathon Oil in an all-stock transaction at an exchange ratio of 0.2486 shares of ConocoPhillips common stock per share of Marathon Oil common stock, representing a premium of 14% to Marathon Oil’s share price at the close of market on May 16, 2024. The proposal did not address any governance matters. A representative of ConocoPhillips also shared a draft of the proposed merger agreement with representatives of Marathon Oil, which included the following terms (i) a “force the vote” provision (i.e. while the Marathon Oil board, under certain circumstances, could change its recommendation in the event of a superior proposal, Marathon Oil could not terminate the merger agreement to enter into an agreement for a superior proposal) (ii) a termination fee equal to 4% of Marathon Oil’s deal equity value that would be payable by Marathon Oil under certain customary circumstances and a termination fee equal to 1% of Marathon Oil’s deal equity value that would be payable if Marathon stockholders did not approve the transaction, (iii) no reverse termination fee payable by ConocoPhillips and (iv) an outside date of 12 months following the signing, subject to two 3-month extensions if required regulatory approvals were not obtained.

Also on May 17, 2024, the ConocoPhillips proposal was provided to the Marathon Oil board, together with a side-by-side summary of the ConocoPhillips proposal, the Party A proposal and the Party B proposal.

On May 21, 2024, the Marathon Oil board held its regularly scheduled meeting, with members of Marathon Oil’s senior management team and a representative from Kirkland & Ellis LLP (which we refer to as “Kirkland”) in attendance. At this meeting, the Marathon Oil board discussed the ConocoPhillips proposal and the proposals from Party A and Party B. The representative of Kirkland discussed the directors’ fiduciary duties in the context of the proposed transactions. The representative from Kirkland also described the material terms of the draft merger agreement received from ConocoPhillips, as well as the draft merger agreement that Kirkland prepared at Marathon Oil’s direction, which reflected provisions more

51

appropriate for a transaction with companies sized more similarly to Party A and Party B. The representative of Kirkland also summarized the material differences between the two draft merger agreements, including with respect to governance, stockholder approval, representations and warranties, competition covenants, interim operating covenants, treatment of equity awards, employment covenants, non-solicitation covenants, closing conditions, termination triggers and fees and expense reimbursement. The Marathon Oil board, with input from a representative of Kirkland, discussed how to appropriately consider the relative strengths and weaknesses of each of the three proposals in light of their fiduciary duties.

On May 22, 2024, the Marathon Oil board continued the regularly scheduled meeting (which we refer to as the “May 22 board meeting”) from the prior day. A portion of this meeting was dedicated to review and consideration of the terms of the proposed transactions with ConocoPhillips, Party A and Party B. At this meeting, members of the Marathon Oil management team reviewed the Marathon Oil internal standalone financial forecasts and strategy (including Marathon Oil’s standalone net asset valuation at strip pricing) and then reviewed the differentiated strategies for each of the potential transactions, comparing each of the potential counterparties’ asset portfolios to Marathon Oil’s asset portfolio. Members of Marathon Oil’s management team noted their view that there would be significant advantages in durability resulting from a transaction with ConocoPhillips and that the ConocoPhillips transaction would be the only option accretive to all of Marathon Oil’s durability metrics. Representatives of Morgan Stanley and Kirkland then joined the meeting, and the Marathon Oil board reviewed materials provided by Morgan Stanley that contained preliminary pro forma financial analysis of each proposed transaction. The Marathon Oil board also reviewed a side-by-side proposal comparison detailing trading statistics, valuation metrics, credit profile and select financial metrics for each of Party A, Party B and ConocoPhillips. The Marathon Oil board discussed recent transaction premia, as well as Morgan Stanley’s analysis on the premia offered by each counterparty. The Marathon Oil board also considered the relative ranking of each potential transaction using the strategic imperatives of scale, durability and resilience, with management noting that a merger with ConocoPhillips would rank first in all three categories. Specifically, ConocoPhillips would offer scale in U.S. basins, enhanced inventory and resource life, portfolio diversity both internationally and with respect to LNG, accretion to oil mix, alignment on return of cash model and cost synergies. The Marathon Oil board discussed and determined that ConocoPhillips would be the preferred counterparty due to its durability and standalone financial performance metrics and the proposed transaction’s accretion to Marathon Oil’s operational and financial metrics. The Marathon Oil board and management also considered the actionability of a transaction with ConocoPhillips after the failed discussions with each of Party A and Party B in 2023. The Marathon Oil board further indicated support for Mr. Tillman to contact Mr. Lance to express the Marathon Oil board’s willingness to consider a proposed transaction at an increased exchange ratio of not less than 0.2500 shares of ConocoPhillips common stock per share of Marathon Oil common stock, representing a premium of 14.5% to Marathon Oil’s share price at the close of market on May 21, 2024.

After the Marathon Oil board meeting on May 22, 2024, Mr. Tillman contacted Mr. Lance by telephone. Messrs. Tillman and Lance discussed ConocoPhillips’ proposal, and Mr. Tillman provided feedback from the Marathon Oil board and indicated that the Marathon Oil board would likely proceed with a proposed transaction with ConocoPhillips at an exchange ratio of 0.2550 shares of ConocoPhillips common stock per share of Marathon Oil common stock. Mr. Lance informed Mr. Tillman that he would revert with an answer on the requested increase to the exchange ratio and further noted that ConocoPhillips intended to continue its due diligence with respect to Marathon Oil.

Later on May 22, 2024, Mr. Lance contacted Mr. Tillman and agreed to an exchange ratio of 0.2550 shares of ConocoPhillips common stock per share of Marathon Oil common stock, subject to further diligence, a negotiated merger agreement and approval of each of the Marathon Oil board and the ConocoPhillips board of directors. The proposed exchange ratio represented a premium of 16.8% to Marathon Oil’s share price at the close of market on May 21, 2024.

On May 23, 2024, the Marathon Oil board convened for a special meeting, with members of the Marathon Oil senior management team in attendance. The Marathon Oil senior management team provided the board with an update on the discussions between Mr. Tillman and Mr. Lance following the May 22 board meeting, including Mr. Tillman’s indication that ConocoPhillips was prepared to pursue a transaction at an exchange ratio of 0.2550 shares of ConocoPhillips common stock per share of Marathon Oil common stock (subject to, among other things, the approval of its board and further diligence).

52

Members of the Marathon Oil management team also provided an update on the ongoing diligence process and next steps with respect to Party A and Party B.

Also on May 23, 2024, Mr. Tillman contacted the chief executive officer of Party B to provide an update regarding the Marathon Oil board’s deliberations. Mr. Tillman stated that Marathon Oil was in receipt of multiple offers and that the Party B proposal was not sufficient and asked that Party B work to submit an enhanced proposal if it was still interested in a transaction with Marathon Oil. Mr. Tillman also noted that time was of the essence and that Marathon Oil would provide a draft merger agreement for Party B’s consideration and an amendment to the parties’ existing confidentiality agreement to extend its term.

On May 23, 2024, Kirkland sent a revised draft of the merger agreement to Wachtell Lipton, ConocoPhillips’ legal counsel. The revised draft of the merger agreement, among other things, (i) removed the force-the-vote provision by adding a termination right for Marathon Oil in the event Marathon Oil receives a superior proposal, (ii) added receipt by Marathon Oil of a tax opinion as a condition to closing of the merger, (iii) reduced the termination fee payable by Marathon Oil under certain circumstances to 2.5% of Marathon Oil’s deal equity value and the termination fee payable by Marathon Oil if Marathon stockholders did not approve the transaction to an unspecified percentage of Marathon Oil’s deal equity value, (iv) added a regulatory termination fee payable by ConocoPhillips in an amount equal to an unspecified multiple of the Marathon Oil termination fee and enhanced ConocoPhillips’s regulatory efforts covenant and (v) proposed an outside date of 12 months following the signing, subject to two 6-month extensions if required regulatory approvals were not obtained

On May 24, 2024, Mr. Tillman contacted the chief executive officer of Party A to provide an update regarding the Marathon Oil board’s deliberations. Mr. Tillman stated that Marathon Oil was in receipt of multiple offers and that, while Party A had submitted a competitive offer, Party A should consider enhancing its offer. Mr. Tillman also noted that time was of the essence and that Marathon Oil would provide a draft merger agreement for Party A’s consideration and an amendment to the parties’ existing confidentiality agreement to extend its term. Later that same day, Marathon Oil and Party A executed the amendment to the confidentiality agreement and representatives of each of Marathon Oil and Party A convened to discuss additional confidential information of Marathon Oil that would be provided via a virtual data room.

On May 24, 2024, Wachtell Lipton sent a revised draft of the merger agreement to Kirkland. The revised draft of the merger agreement, among other things, (i) accepted the removal of the force-the-vote provision, (ii) removed the tax opinion closing condition, (iii) increased the termination fee payable by Marathon Oil under certain circumstances to 3.75% of Marathon Oil’s deal equity value and proposed a termination fee equal to 0.75% of Marathon Oil’s deal equity value in the event Marathon Oil stockholders did not approve the transaction, (iv) removed the regulatory termination fee payable by ConocoPhillips, reduced ConocoPhillips’ regulatory efforts covenant and added certain regulatory closing conditions and (v) proposed an outside date of 12 months following the signing, subject to two 3-month extensions if required regulatory approvals were not obtained.

On May 24, 2024, representatives of Party B contacted representatives of Marathon Oil to solicit additional clarity regarding timing. Representatives of Marathon Oil reiterated that time was of the essence.

Between May 25, 2024 and May 28, 2024, representatives of Kirkland and Wachtell Lipton exchanged various drafts of the merger agreement and the parties reached alignment, among other things, on the required regulatory approvals, the outside date construct, the regulatory efforts covenant, the amount of the termination fees payable by Marathon Oil under certain circumstances, equity award treatment, employee matters and the interim operating covenants.

On May 26, 2024, Marathon Oil and Party B executed the amendment to the confidentiality agreement. Later that same day, representatives of Marathon Oil shared a draft merger agreement with Party A and Party B.

On May 27, 2024, representatives of each of Marathon Oil, Kirkland, ConocoPhillips and Wachtell Lipton conducted reciprocal legal due diligence calls.

In the morning on May 28, 2024, the Marathon Oil board convened a meeting, together with members of Marathon Oil’s senior management team and representatives from Morgan Stanley and Kirkland in

53

attendance. Representatives from Kirkland provided a summary of the merger agreement with ConocoPhillips and reviewed key terms of the merger agreement. Members of the Marathon Oil management team also provided an update on the diligence performed on ConocoPhillips. Representatives of Morgan Stanley then reviewed certain financial analysis relating to the potential transaction. Thereafter, following the departure of the representatives of Morgan Stanley, the Marathon Oil board reviewed Morgan Stanley’s customary disclosures regarding Morgan Stanley’s prior relationship with Marathon Oil and ConocoPhillips. The Marathon Oil board concluded that such relationships would not interfere with Morgan Stanley’s ability to provide advisory services to Marathon Oil.

Also on May 28, 2024, representatives of Marathon Oil, Kirkland, Morgan Stanley, ConocoPhillips and Wachtell Lipton conducted a confirmatory business due diligence call on ConocoPhillips.

Later on May 28, 2024, the Marathon Oil board held another meeting to consider approval of the merger agreement, with members of Marathon Oil’s management team as well as representatives from Morgan Stanley and Kirkland in attendance. At the meeting, representatives of Kirkland detailed the changes to the key terms of the merger agreement. Representatives of Morgan Stanley then reviewed certain financial information that was used in connection with its fairness opinion, consistent with the information reviewed with the Marathon Oil board in the morning of May 28, 2024. Thereafter, Morgan Stanley orally rendered its fairness opinion to the Marathon Oil board that, as of May 28, 2024, and based on and subject to the assumptions, qualifications, limitations and other matters as set forth therein, the merger consideration to be received by holders of shares of Marathon Oil pursuant to the merger agreement was fair, from a financial point of view, to holders of Marathon Oil common stock (other than ConocoPhillips and Merger Sub and their respective affiliates). Morgan Stanley subsequently confirmed its fairness opinion in writing. Morgan Stanley’s opinion is more fully described in the section of this proxy statement/​prospectus titled “The Merger — Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor” beginning on page 58. After discussion, the Marathon Oil board unanimously determined that it is in the best interests of Marathon Oil and the holders of Marathon Oil common stock, and declared it advisable, for Marathon Oil to enter into the merger agreement and resolved to recommend that the holders of Marathon Oil common stock adopt and approve the merger agreement, the merger and the other transactions contemplated by the merger agreement.

Following the approval of the Marathon Oil board, later in the evening on May 28, 2024, the parties proceeded with the execution of the merger agreement and, prior to markets opening on May 29, 2024, issued a joint press release announcing the transaction.

Recommendation of the Marathon Oil Board of Directors and Reasons for the Merger

By unanimous vote, the Marathon Oil board, at a meeting held on May 28, 2024, (i) determined that the merger agreement and the transactions contemplated thereby, including the merger, are fair to, and in the best interests of, Marathon Oil and the Marathon Oil stockholders, (ii) approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger and (iii) resolved to recommend that the Marathon Oil stockholders approve and adopt the merger agreement and the transactions contemplated thereby, including the merger. The Marathon Oil board unanimously recommends that Marathon Oil stockholders vote “FOR” the merger proposal, “FOR” the non-binding compensation advisory proposal and “FOR” the adjournment proposal.

In the course of reaching its determination and recommendation, the Marathon Oil board met several times to consider a potential transaction with ConocoPhillips, including in executive session, and consulted with Marathon Oil’s senior management, outside legal counsel and financial advisors. In addition, the Marathon Oil board considered a number of factors, including the following factors (not necessarily in order of relative importance) which the Marathon Oil board viewed as being generally positive or favorable in coming to its determination and recommendation:

•

Value and nature of the consideration to be received in the merger by Marathon Oil’s stockholders.

•

Use of equity in the merger.   The all-stock consideration enables Marathon Oil’s stockholders to have a continued ownership position in the combined company (approximately 11% of the combined company based on the issued and outstanding shares of Marathon Oil common stock and ConocoPhillips common stock on May 28, 2024) and participate in the value and

54

opportunities of the combined company after the merger, including dividends, stock buybacks, synergies, potential future increases in commodity prices and expected future growth.

•

Capital return.   ConocoPhillips return of capital framework is based on cash from operations and strongly aligns with the Marathon Oil return of cash model with both using a combination of dividends and share repurchases to achieve peer leading stockholder distributions. ConocoPhillips has historically paid a quarterly base dividend ($0.58 per share for the most recently completed quarter prior to Marathon Oil’s entry into the merger agreement), reflecting a commitment to returning capital to stockholders and protecting its dividend. The Marathon Oil board believes that the combined company will have significant financial flexibility to continue ConocoPhillips’ dividend payments and its capital return philosophy.

•

Premium.   The exchange ratio of 0.2550 shares of ConocoPhillips common stock for each share of Marathon Oil common stock applied to the closing price of Marathon Oil common stock on the last full trading day prior to the finalization of the merger agreement (which we refer to as “Marathon Oil’s Unaffected Stock Price”) represents a 14.7% premium to Marathon Oil’s Unaffected Stock Price.

•

ConocoPhillips stock.   The Marathon Oil board believes that the shares of ConocoPhillips common stock that will be delivered to Marathon Oil stockholders as merger consideration are a highly attractive currency that will benefit both near and long term from the combination’s significant synergies described in more detail below.

•

Benefits of a combined company.

•

Scale.   The Marathon Oil board expects that the global scale of the combined company, which will have an expanded resource base, will reduce cash flow volatility and increase resiliency, better support strategic investment and drive long-term value creation. Further, Marathon Oil operates in an industry that faces significant potential financial and operating risks associated with geopolitical, environmental and other regulatory considerations and growing pressure to diversify away from fossil fuels, which may threaten Marathon Oil’s long-term valuation and access to capital as a standalone entity. The combined company’s larger, diversified asset portfolio will de-risk Marathon Oil’s current portfolio and lessen any potential future impact from legal or regulatory changes or initiatives in the United States or elsewhere. The Marathon Oil board expects that the increased scale will also provide the combined company with improved ability to withstand the inherent price volatility associated with a commodity business.

•

Durability.   The Marathon Oil board considered that the combined company will have greater durability of inventory and resource life, as well as a more diversified portfolio with a balanced but oil weighted production mix and a stronger international presence.

•

Resilience.    The Marathon Oil board expects that the combined company will have a stronger balance sheet and that the merger will be credit-enhancing. The Marathon Oil board also expects that the size of the combined company will lead to a materially lower cost of capital and that the combined company will have low cost of supply, which will lead to improved credit ratings, enhanced capital efficiency, lower enterprise free cash flow breakeven and improved access to capital markets.

•

Combined business governance and leadership.   The combined company will be overseen by the ConocoPhillips executive management team who have a track record of delivering value for stockholders through asset acquisitions, integration and successful execution of capital deployed. Governance is provided by an experienced, diverse board, which will consist of the current ConocoPhillips directors.

•

Low capital intensity.   The Marathon Oil board expects that the Marathon Oil stockholders will benefit from the combined company’s low-capital-intensity resource base, which will be underpinned by a low decline rate and will provide sustainability in future free cash flow growth and capital returns to stockholders.

•

Synergies.   The Marathon Oil board expects that the merger will result in Marathon Oil stockholders being able to participate in an estimated $500 million of run rate cost and capital

55

savings within the first full year following the closing of the transaction, which will come from reduced general and administrative costs, lower operating costs and improved capital efficiencies.

•

Shared values.   Marathon Oil and ConocoPhillips share core values of safety, integrity, collaboration, accountability and caring for people and the environment, and the combined workforce is expected to continue to increase efficiency and deliver stockholder value. The companies also share a commitment to ESG excellence, and the Marathon Oil board believes that the transaction is constructive to all of Marathon Oil’s sustainability objectives.

•

Other benefits.   The Marathon Oil board also considered various other expected benefits of the combined company to Marathon Oil stockholders, including the opportunity to (i) share each company’s technical expertise with immediate knowledge transfer in the combined company, (ii) combine exceptional technical teams with similar execution-focused cultures, (iii) retain talented workforce with the combined company continuing to be headquartered in Houston, TX and (iv) capture efficiencies from large scale, multi-well projects and well design optimization.

•

Superior alternative to other transactions potentially available to Marathon Oil.   Following consultation with Marathon Oil’s management and financial advisors, the Marathon Oil board believed it was unlikely an alternative strategic counterparty would be willing to engage in a transaction that would provide Marathon Oil stockholders with greater value, including the opportunity to benefit from cost savings and synergies and from future value creation, than is being provided in connection with the merger. The Marathon Oil board evaluated relative valuation, financial accretion, balance sheet strength, durability of resource life, scale, industrial logic and investor relevance, among other factors, and believed that the durability resulting from a transaction with ConocoPhillips would be significantly greater than would result from a transaction with other potential counterparties.

•

Superior alternative to continuation of standalone Marathon Oil.   The Marathon Oil board considered Marathon Oil’s business, prospects and other strategic opportunities and the risks of remaining as a standalone public company, including the risks associated with increasing social, political and environmental pressure and resource scarcity. Based on these considerations, the Marathon Oil board believed the value offered to Marathon Oil’s stockholders pursuant to the merger would be more favorable to them than the potential value that might reasonably be expected to result from remaining a standalone public company.

•

Receipt of fairness opinions and presentations from Morgan Stanley.   The Marathon Oil board considered the financial analyses that were reviewed and discussed with representatives of Morgan Stanley, as well as the oral opinions of Morgan Stanley rendered to the Marathon Oil board on May 28, 2024, which opinion was subsequently confirmed by delivery of a written opinion dated May 28, 2024, as to the fairness, from a financial point of view, to the holders of Marathon Oil common stock (other than ConocoPhillips, Merger Sub and their respective affiliates) of the merger consideration provided in the merger agreement.

•

Opportunity to receive alternative acquisition proposals.   The Marathon Oil board considered the terms of the merger agreement related to the Marathon Oil board’s ability to respond to unsolicited competing proposals and determined that third parties would be unlikely to be deterred from making a competing proposal by the provisions of the merger agreement, including because the Marathon Oil board may, under certain circumstances, furnish information or enter into discussions in connection with a competing proposal. In this regard, the Marathon Oil board considered that:

•

subject to its compliance with the merger agreement, the Marathon Oil board can change its recommendation to Marathon Oil stockholders with respect to the adoption of the merger agreement prior to obtaining stockholder approval if the Marathon Oil board determines in good faith (after consultation with its financial advisors and outside legal advisors) that, with respect to a superior proposal or an intervening event, the failure to take such action would be inconsistent with the Marathon Oil board’s fiduciary duties; and

•

while the merger agreement contains a termination fee of $557 million that Marathon Oil would be required to pay to ConocoPhillips in certain circumstances, including if ConocoPhillips terminates the merger agreement in connection with a change in the Marathon Oil board’s recommendation to stockholders with respect to adoption of the merger agreement, if Marathon

56

Oil, its subsidiaries or certain representatives of Marathon Oil violate the non-solicitation obligations under the merger agreement or if Marathon Oil terminates the merger agreement to enter into a definitive agreement with respect to a superior proposal, the Marathon Oil board believed that this fee is reasonable in light of the circumstances and the overall terms of the merger agreement, consistent with fees and provisions in comparable transactions and not preclusive of other offers.

•

Tax considerations.   The Marathon Oil board considered that the merger is intended to qualify for federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code.

•

Likelihood of completion and terms of the merger agreement.   The Marathon Oil board considered the likelihood of completion of the merger to be significant, in light of, among other things, the belief that, in consultation with Marathon Oil’s legal advisors, the terms of the merger agreement, taken as a whole, including the parties’ representations, warranties, covenants (including the restrictions on ConocoPhillips’ ability to make certain other acquisitions) and conditions to closing of the merger, and the circumstances under which the merger agreement may be terminated, are reasonable.

The Marathon Oil board also considered a number of uncertainties, risks and factors it deemed generally negative or unfavorable in making its determination, approval and related recommendation, including the following (not necessarily in order of relative importance):

•

Possible failure to achieve synergies.   The Marathon Oil board considered the potential challenges and difficulties in integrating the operations of Marathon Oil and ConocoPhillips and the risk that anticipated cost savings and operational efficiencies between the two companies, or other anticipated benefits of the merger, might not be realized or might take longer to realize than expected.

•

Fixed exchange ratio.   The Marathon Oil board considered that, because the merger consideration is based on a fixed exchange ratio rather than a fixed value, Marathon Oil stockholders bear the risk of a decrease in the trading price of ConocoPhillips common stock during the pendency of the merger and the fact that the merger agreement does not provide Marathon Oil with a collar or a value-based termination right.

•

Risks associated with the pendency of the merger.   The Marathon Oil board considered the risks and contingencies relating to the announcement and pendency of the merger (including the likelihood of litigation or other opposition brought by or on behalf of Marathon Oil stockholders challenging the merger and the other transactions contemplated by the merger agreement) and the risks and costs to Marathon Oil if the completion of the merger is not accomplished in a timely manner or if the merger does not close at all, including potential employee attrition, the impact on Marathon Oil’s relationships with third parties and the effect termination of the merger agreement may have on the trading price of Marathon Oil common stock and Marathon Oil’s operating results.

•

Interim operating covenants.   The Marathon Oil board considered the restrictions on the conduct of Marathon Oil’s and its subsidiaries’ businesses during the period between the execution of the merger agreement and the completion of the merger as set forth in the merger agreement.

•

Competing proposals; termination fees; expense reimbursement.   The Marathon Oil board considered the possibility that a third party may be willing to enter into a strategic combination with Marathon Oil on terms more favorable than the merger. In connection therewith, the Marathon Oil board considered the terms of the merger agreement relating to no shop covenants and termination fees and the potential that such provisions might deter alternative bidders that might have been willing to submit a superior proposal to Marathon Oil. The Marathon Oil board also considered that, under specified circumstances, Marathon Oil may be required to pay a termination fee or expenses in the event the merger agreement is terminated and the effect this could have on Marathon Oil, including:

•

the possibility that the termination fee could discourage other potential parties from making a competing offer; although the Marathon Oil board believed that the termination fee amount is reasonable and will not unduly deter any other party that might be interested in making a competing proposal;

•

if the merger is not consummated, Marathon Oil will pay its own expenses incident to preparing for and entering into and carrying out its obligations under the merger agreement and the transactions contemplated thereby; and

57

•

the requirement that if the merger agreement is terminated as a result of the failure to obtain approval of Marathon Oil stockholders, Marathon Oil will be obligated to reimburse ConocoPhillips $86 million for its expenses in connection with the merger agreement.

•

Interests of Marathon Oil directors and executive officers.   The Marathon Oil board considered that Marathon Oil’s directors and executive officers may have interests in the merger that may be different from, or in addition to, those of Marathon Oil stockholders. For more information about such interests, see below under the heading “— Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72.

•

Merger costs.   The Marathon Oil board considered the costs associated with the completion of the merger, including management’s time and energy and potential opportunity cost.

•

Regulatory approval.   The Marathon Oil board considered that the merger and the related transactions require regulatory approvals to complete such transactions and the risk that the applicable governmental entities may seek to impose unfavorable terms or conditions, or otherwise fail to grant, such approval.

•

Other risks.   The Marathon Oil board considered risks of the type and nature described under the sections entitled “Risk Factors” beginning on page 26 and “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 37.

The Marathon Oil board believed that, overall, the potential benefits of the merger to Marathon Oil stockholders outweighed the risks and uncertainties of the merger.

The foregoing discussion of factors considered by the Marathon Oil board in reaching its conclusions and recommendation includes the principal factors considered by the Marathon Oil board but is not intended to be exhaustive and may not include all of the factors considered by the Marathon Oil board, but includes the material factors considered by the Marathon Oil board. In light of the variety of factors considered in connection with its evaluation of the merger, the Marathon Oil board did not find it practicable to, and did not, quantify or otherwise assign relative or specific weights to the specific factors considered in reaching its determinations and recommendations. Rather, the Marathon Oil board viewed its decisions as being based on the totality of the factors and information it considered. Moreover, each member of the Marathon Oil board applied his or her own personal business judgment to the process and may have given different weight to different factors.

Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor

Marathon Oil retained Morgan Stanley to provide it with financial advisory services in connection with the merger and to provide a financial opinion to the Marathon Oil board. Marathon Oil selected Morgan Stanley to act as its exclusive financial advisor based on Morgan Stanley’s qualifications, expertise, and reputation and its knowledge of the business and affairs of Marathon Oil. On May 28, 2024, at a meeting of the Marathon Oil board, Morgan Stanley rendered its oral opinion, subsequently confirmed by delivery of a written opinion, dated May 28, 2024, that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth in the written opinion, the merger consideration to be received by holders of shares of Marathon Oil common stock pursuant to the merger agreement was fair, from a financial point of view, to the holders of Marathon Oil common stock (other than ConocoPhillips, Merger Sub and their respective affiliates).

The full text of the written opinion of Morgan Stanley delivered to the Marathon Oil board, dated as of May 28, 2024, is attached as Annex B to this proxy statement/prospectus and is incorporated herein by reference in its entirety.

Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to Morgan Stanley by Marathon Oil, and formed a substantial basis for Morgan Stanley’s opinion. With respect to the Marathon Oil Management Projections, Morgan Stanley assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Marathon Oil of the future financial performance of Marathon Oil. With respect to the Marathon Oil Street Projections (as defined below), at the direction of Marathon Oil, Morgan Stanley assumed that they were reasonable bases upon which to evaluate the business and financial prospects of Marathon Oil. Morgan Stanley expresses no view as to the Marathon Oil Management Projections or the Marathon Oil Street Projections or the assumptions on which they were based. In addition, Morgan Stanley has assumed that the merger will be consummated in accordance with the terms set forth in the merger agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the merger will be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended, and that the definitive merger agreement will not differ in any material respect from the draft thereof furnished to Morgan Stanley.

Events occurring after the date hereof may affect Morgan Stanley’s opinion and the assumptions used in preparing it, and Morgan Stanley does not assume any obligation to update, revise or reaffirm Morgan Stanley’s opinion.

Summary of Financial Analyses of Morgan Stanley

The following is a summary of the material financial analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its written opinion to the Marathon Oil board, both provided as of May 28, 2024. The following summary is not a complete description of the financial analyses performed and factors considered by Morgan Stanley in connection with its opinion, nor does the order of analyses described represent the relative importance or weight given to those analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before May 24, 2024, the last full trading day prior to the date of Morgan Stanley’s opinion. Some of these summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. The analyses listed in the tables and described below must be considered as a whole. Assessing any portion of such analyses and of the factors reviewed, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Morgan Stanley’s opinion. Furthermore, mathematical analysis is not in itself a meaningful method of using the data referred to below.

In performing the financial analyses summarized below and in arriving at its opinion, at the direction of Marathon Oil, Morgan Stanley utilized and relied upon the Marathon Oil Management Projections and the Marathon Oil Street Projections, each of which were approved by Marathon Oil management and the Marathon Oil board for Morgan Stanley’s use in connection with its financial analyses and which are described below. In addition, Morgan Stanley utilized and relied upon the number of issued and outstanding shares of Marathon Oil and ConocoPhillips provided by management of Marathon Oil and ConocoPhillips, respectively. For further information regarding the financial projections, see the section entitled “Marathon Oil Unaudited Forecasted Financial Information” beginning on page 66.

As used in this section, the following terms have the following meanings:

•

“Adj. EBITDAX” refers to net income (loss) before net interest expense, income tax expense (benefit), depreciation, depletion, and amortization, (gains) losses on derivative instruments, exploitations and exploration expense and certain other expenses.

•

“Price” refers to market capitalization.

•

“AV” refers to aggregate value, calculated as market capitalization plus net debt, preferred equity and minority interests.

60

•

“Marathon Oil Unlevered Free Cash Flow” refers to Adj. EBITDAX less cash taxes, exploitations and exploration costs, capital expenditures and certain other operating expenses.

•

“Cash Flow” refers to Adj. EBITDAX less exploitation and exploration costs, cash interest expense, cash tax expense and certain other operating expenses.

Discounted Cash Flow Analysis

Morgan Stanley performed a discounted cash flow analysis, which is designed to provide an implied value of a company by calculating the present value of the estimated future unlevered free cash flows and terminal value of such company. Morgan Stanley calculated a range of implied equity values per share of Marathon Oil common stock as of March 31, 2024, based on estimates of future unlevered free cash flows for the second, third and fourth quarters of 2024 and fiscal years 2025 through 2028 contained in the Marathon Oil Management Projections, including net debt of Marathon Oil as of March 31, 2024 of $5,401 million, and based on the estimated number of fully diluted shares of Marathon Oil common stock, as of May 24, 2024, as provided by Marathon Oil’s management and calculated using the treasury stock method. Morgan Stanley also calculated a range of terminal values for Marathon Oil based on a LTM Adj. EBITDAX exit multiple range of 4.5x to 5.5x, which was selected based on Morgan Stanley’s professional judgment and experience. The estimated unlevered free cash flows and the range of terminal values were then discounted to present value as of March 31, 2024 using mid-year discounting convention by applying a discount rate range of 8.0% to 9.4%, which was selected based on Morgan Stanley’s professional judgment and experience, to reflect Marathon Oil’s estimated weighted average cost of capital (“WACC”). This analysis indicated a range of implied equity values per share of Marathon Oil common stock of $26.50 to $34.00, each rounded to the nearest $0.25. Morgan Stanley compared the foregoing range of implied equity values per share of Marathon Oil common stock to the closing trading price of Marathon Oil common stock on May 24, 2024 (which was the last full trading day prior to finalization of the merger agreement) of $25.56 per share of Marathon Oil common stock.

Comparable Company Analysis

In order to assess how the public market values shares of similar publicly traded companies, Morgan Stanley reviewed and compared specific financial and operating data relating to Marathon Oil with selected companies that Morgan Stanley deemed comparable to Marathon Oil, based on size, location of assets, expected growth and leverage profile.

Morgan Stanley analyzed, among other things, the following financial metrics of each of the comparable companies as of May 24, 2024:

•

the ratio of AV to 2024 and 2025 estimated Adj. EBITDAX (based on median research consensus per S&P Capital IQ (such median research consensus we refer to, for purposes of this section titled “— Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor,” as “Marathon Oil Street Projections”)); and

•

the ratio of Price to estimated 2024 and 2025 cash flow (based on Marathon Oil Street Projections).

For purposes of the Marathon Oil Street Projections, consistent with customary market practice and based on Morgan Stanley’s professional judgment and experience, for purposes of the following analyses, Morgan Stanley relied solely on estimated 2024 and 2025 Adj. EBITDAX and cash flow.

The metrics for each of the comparable companies of Marathon Oil are summarized as follows:

Comparable Companies of Marathon Oil	AV /​ 2024E Adj. EBITDAX		AV /​ 2025E Adj. EBITDAX		Price / 2024E Cash Flow Per Share		Price / 2025E Cash Flow Per Share
Devon Energy Corporation	​	4.8x	​	4.7x	​	4.4x	​	4.5x
Coterra Energy Inc.	​	5.8x	​	4.6x	​	6.2x	​	5.3x
Marathon Oil	​	4.4x	​	4.2x	​	3.6x	​	3.5x
Ovintiv Inc.	​	4.0x	​	3.8x	​	3.1x	​	3.1x

61

Comparable Companies of Marathon Oil	AV /​ 2024E Adj. EBITDAX		AV /​ 2025E Adj. EBITDAX		Price / 2024E Cash Flow Per Share		Price / 2025E Cash Flow Per Share
Permian Resources Corporation	​	4.3x	​	4.1x	​	3.6x	​	3.5x
Chord Energy Corporation	​	4.5x	​	4.0x	​	4.6x	​	4.3x
APA Corporation	​	3.1x	​	2.9x	​	2.6x	​	2.3x

Based on the analysis of the relevant metrics for each of the comparable companies, and the application of its professional judgment and experience (which included the exclusion of outliers and weighting more heavily the comparable companies that Morgan Stanley deemed most comparable to Marathon Oil in the relevant metrics), Morgan Stanley selected a reference range of financial multiples of the comparable companies and applied this range of multiples to the relevant Marathon Oil financial statistics (based on estimates for Marathon Oil Adj. EBITDAX and Cash Flow, in each case, from the Marathon Oil Street Projections).

Based on the estimated number of fully diluted shares of Marathon Oil, as of May 24, 2024, as provided by Marathon Oil management and calculated using the treasury stock method, Morgan Stanley calculated the following ranges of the implied per share values of Marathon Oil common stock, each rounded to the nearest $0.25:

Public Trading Comparables of Marathon Oil	Marathon Oil Statistic	Reference Range	Implied Value Per Share Range for Marathon Oil
AV Value to Estimated 2024 Adj. EBITDAX	$4,559MM	4.0x – 5.0x	$22.75 – $30.75
AV Value to Estimated 2025 Adj. EBITDAX	$4,736MM	3.5x – 4.5x	$19.75 – $28.25
Price to Estimated 2024 Cash Flow	$4,038MM	3.5x – 4.5x	$25.00 – $32.25
Price to Estimated 2025 Cash Flow	$4,164MM	3.25x – 4.25x	$24.00 – $31.25

Morgan Stanley noted that the closing price of Marathon Oil common stock was $25.56 per share on May 24, 2024 (which was the last full trading day prior to finalization of the merger agreement), and the implied price of Marathon Oil common stock based on the exchange ratio pursuant to the merger agreement was $29.90 per share.

No company utilized in the comparable company analysis is identical to Marathon Oil. In evaluating comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions, and other matters, which are beyond the control of Marathon Oil. These include, among other things, the impact of competition on the business of Marathon Oil and the industry generally, industry growth, and the absence of any adverse material change in the financial condition and prospects of Marathon Oil or the industry, or in the financial markets in general.

Precedent Transactions Analysis

Morgan Stanley performed a precedent transactions analysis, which is designed to imply a value of a company based on publicly available financial terms for selected transactions.

In connection with its analysis, Morgan Stanley compared publicly available statistics for 27 transactions involving U.S. public company exploration and production targets announced between 2018 and May 2024 with an AV of at least $1.0 billion. Morgan Stanley deemed these U.S. public company transactions to be comparable based on target asset location, transaction size and transaction structure.

For purposes of the analysis of the precedent transactions, Morgan Stanley analyzed, among other things, the ratio of AV to the last 12 months’ Adj. EBITDAX of the target company.

Not meaningful as the transaction was identified as an outlier.

Based on the analysis of the relevant metrics for each of the precedent transactions, and upon the application of its professional judgment and experience (which included the exclusion of outliers and weighting more heavily the precedent transactions which Morgan Stanley deemed most comparable to the contemplated combination between Marathon Oil and ConocoPhillips in the relevant metrics), Morgan Stanley selected a representative range of financial multiples of the precedent transactions and applied this range of multiples to the historical values for the 12 months ended March 31, 2024 of Marathon Oil, provided by Marathon Oil management.

Based on the estimated number of fully diluted shares of Marathon Oil, as of May 24, 2024, as provided by Marathon Oil management and calculated using the treasury stock method, Morgan Stanley calculated the following ranges of the implied per share value of Marathon Oil common stock, rounded to the nearest $0.25:

63

Precedent Transactions	Marathon Oil Statistic			Reference Range		Implied Value Per Share Range for Marathon Oil
AV to LTM 2024 Adj. EBITDAX	​	$	4,416MM	​	4.0x – 6.0x	​	$	21.75 – $37.25

Morgan Stanley noted that the closing price of Marathon Oil common stock was $25.56 per share on May 24, 2024 (which was the last full trading day prior to finalization of the merger agreement), and the implied price of Marathon Oil common stock based on the exchange ratio pursuant to the merger agreement was $29.90 per share.

No company or transaction utilized in the precedent transaction analysis is identical to Marathon Oil or the merger. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to general business, market and financial conditions, and other matters, which are beyond the control of Marathon Oil. These include, among other things, the impact of competition on the business of Marathon Oil or the industry generally, industry growth and the absence of any adverse material change in the financial condition of Marathon Oil, the industry, or in the financial markets in general, which could affect the public trading value of the companies and the aggregate value and equity value of the transactions to which they are being compared.

Equity Research Analysts’ Price Targets

For reference purposes only, Morgan Stanley reviewed the price targets for Marathon Oil common stock prepared and published by 15 equity research analysts as of May 24, 2024 and the range, each rounded to the nearest $0.25, of the (a) undiscounted price targets for shares of Marathon Oil common stock was $28.00 per share to $45.00 per share and (b) discounted price targets for shares of Marathon Oil common stock was $25.25 per share to $40.75 per share.

The price targets published by equity research analysts do not necessarily reflect current market trading prices for shares of Marathon Oil common stock and these estimates are subject to uncertainties, including the future financial performance of Marathon Oil and future financial market conditions.

Morgan Stanley noted that the equity research analysts’ price targets were presented for reference purposes only and were not relied upon for valuation purposes.

General

In connection with the review of the merger agreement and the transactions contemplated thereby by the Marathon Oil board, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor that it considered. Morgan Stanley believes that selecting any portion of its analyses,

64

without considering all of the analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley’s view of the actual value of Marathon Oil. In performing its analyses, Morgan Stanley made numerous judgments and assumptions with regard to industry performance, general business, regulatory, economic, market and financial conditions, and other matters, many of which are beyond the control of Marathon Oil. These include, among other things, the impact of competition on the business of Marathon Oil and the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of Marathon Oil or the industry, or in the financial markets in general. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness, from a financial point of view, to the holders of the Marathon Oil common stock (other than ConocoPhillips, Merger Sub and their respective affiliates) of the merger consideration pursuant to the merger agreement and in connection with the rendering of its oral opinion, subsequently confirmed by delivery of a written opinion, dated May 28, 2024, to the Marathon Oil board. These analyses do not purport to be appraisals or to reflect the prices at which shares of Marathon Oil common stock might actually trade following the consummation of the merger or at any time.

The merger consideration to be received by holders of Marathon Oil common stock pursuant to the merger agreement was determined by Marathon Oil and ConocoPhillips through arm’s-length negotiations between Marathon Oil and ConocoPhillips and was approved by the Marathon Oil board. Morgan Stanley provided advice to Marathon Oil during these negotiations. Morgan Stanley did not, however, recommend any specific merger consideration to Marathon Oil or the Marathon Oil board or opine that any specific merger consideration constituted the only appropriate merger consideration for the merger. Morgan Stanley’s opinion did not address the relative merits of the merger as compared to any other alternative business transaction, or other alternatives, or whether or not such alternatives could be achieved or are available. In addition, Morgan Stanley’s opinion was not intended to, and did not, in any manner, address the price at which the ConocoPhillips common stock would trade following the merger or at any time, and Morgan Stanley expressed no opinion or recommendation to any holder of shares of Marathon Oil common stock as to how such holder should vote at the Marathon Oil special meeting, or whether to take any other action with respect to the merger.

Morgan Stanley’s opinion and its presentation to the Marathon Oil board was one of many factors taken into consideration by the Marathon Oil board in deciding to consider, approve and declare the advisability of the merger agreement and the transactions contemplated thereby and to recommend the approval of the merger by holders of Marathon Oil common stock. Consequently, the analyses described above should not be viewed as determinative of the opinion of the Marathon Oil board with respect to the merger consideration pursuant to the merger agreement or of whether the Marathon Oil board would have been willing to agree to different merger consideration.

Morgan Stanley’s opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with Morgan Stanley’s customary practice.

Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Its securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of their customers, in debt or equity securities or loans of ConocoPhillips, Marathon Oil or any other company, or any currency or commodity, that may be involved in the transactions contemplated by the merger agreement, or any related derivative instrument.

65

Under the terms of its engagement letter, Morgan Stanley provided the Marathon Oil board with financial advisory services and a financial opinion described in this section and attached as Annex B to this proxy statement/prospectus in connection with the merger. Marathon Oil has agreed to pay Morgan Stanley for its services in connection with the merger an aggregate fee, a significant portion of which is contingent upon the closing of the merger, which is estimated, as of the date of this proxy statement/​prospectus, to be approximately $42 million (which we refer to as the “Morgan Stanley Transaction Fee”), $2.5 million of which was payable upon the rendering of a financial opinion to the Marathon Oil board, which will be credited against the Morgan Stanley Transaction Fee payable if the Merger is consummated. Marathon Oil has also agreed to reimburse Morgan Stanley for its reasonable expenses, including fees of outside counsel and other professional advisors, incurred in connection with its engagement. In addition, Marathon Oil has agreed to indemnify Morgan Stanley and its affiliates, their respective officers, directors, employees, advisors and agents and each other person, if any, controlling Morgan Stanley or any of its affiliates against certain losses, claims, damages and liabilities relating to or arising out of or in connection with Morgan Stanley’s engagement.

Morgan Stanley holds an aggregate interest of between 2% and 3% in Marathon Oil common stock and between 1% and 2% in ConocoPhillips common stock, which interests are held in connection with Morgan Stanley’s (i) investment management business, (ii) wealth management business, including client discretionary accounts or (iii) ordinary course trading activities, including hedging activities. In the two years prior to the date of Morgan Stanley’s opinion, Morgan Stanley and its affiliates provided financial advisory and financing services to Marathon Oil and received aggregate fees of approximately between $15.0 million and $20.0 million for such services. In the two years prior to the date of Morgan Stanley’s opinion, Morgan Stanley and its affiliates provided financing services to ConocoPhillips and received fees of approximately between $1.0 million and $2.0 million for such services. As of the date of the merger agreement, Morgan Stanley is providing financial advisory services to ConocoPhillips, unrelated to the Merger, for which Morgan Stanley expects to receive customary fees if such transactions are completed. Morgan Stanley expects that such fees would be significantly less than the fees Morgan Stanley would receive from Marathon Oil in the merger. Morgan Stanley may seek to provide financial advisory and financing services to Marathon Oil and ConocoPhillips and their respective affiliates in the future and would expect to receive fees for the rendering of these services.

Marathon Oil Unaudited Forecasted Financial Information

Marathon Oil does not, as a matter of course, publicly disclose long-term projections as to future revenues, earnings or other results due to, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. However, certain non-public financial forecasts covering multiple years which were prepared by Marathon Oil management and not for public disclosure, were provided to the Marathon Oil board and ConocoPhillips in connection with their evaluations of the merger and were also provided to Morgan Stanley, Marathon Oil’s financial advisor, and ConocoPhillips’ financial advisor for their use in advising their clients and reliance in connection with their financial analyses and opinions as described in the section entitled “The Merger — Opinion of Morgan Stanley, Marathon Oil’s Financial Advisor” beginning on page 58.

The summaries of these financial forecasts presented below are not being included in this proxy statement/​prospectus to influence your decision whether to vote for or against the merger proposal but are being included because these forecasts were made available to the Marathon Oil board, Marathon Oil’s financial advisor and ConocoPhillips and its financial advisor. The Marathon Oil forecasted financial information was prepared by Marathon Oil management.

The inclusion of this information should not be regarded as an indication that the Marathon Oil board, Marathon Oil, ConocoPhillips (or any of their respective affiliates, officers, directors, advisors or other representatives) or any other person considered, or now considers, the Marathon Oil forecasted financial information to be necessarily predictive of actual future events or results of Marathon Oil’s or ConocoPhillips’ operations and should not be relied upon as such. Marathon Oil management’s internal financial forecasts, upon which the Marathon Oil forecasted financial information was based, are subjective in many respects. There can be no assurance that the Marathon Oil forecasted financial information will be realized or that actual results will not be significantly higher or lower than forecasted. The Marathon Oil forecasted financial

66

information covers multiple years and such information by its nature becomes less predictive with each successive year. As a result, the Marathon Oil forecasted financial information summarized in this proxy statement/prospectus should not be relied on as necessarily predictive of actual future events.

In addition, the Marathon Oil forecasted financial information was not prepared with a view toward compliance with GAAP, 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 forecasted financial information included in this document has been prepared by, and is the responsibility of, Marathon Oil’s management. PricewaterhouseCoopers LLP, Marathon Oil’s independent registered public accounting firm, has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying forecasted financial information and, accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP report incorporated by reference in this document relates to Marathon Oil’s previously issued financial statements. It does not extend to the forecasted financial information and should not be read to do so. Furthermore, ConocoPhillips’ independent registered public accounting firm, Ernst & Young LLP, has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the Marathon Oil forecasted financial information and accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto. The report of Ernst & Young LLP contained in ConocoPhillips’ Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated by reference into this proxy statement/prospectus, relates only to historical financial information of ConocoPhillips, and such report does not extend to the Marathon Oil forecasted financial information included below and should not be read to do so.

The Marathon Oil forecasted financial information was based on numerous variables and assumptions that were deemed to be reasonable as of the respective dates when such projections were finalized. However, such assumptions are inherently uncertain and difficult or impossible to predict or estimate and most of them are beyond Marathon Oil’s control. Assumptions that were used by Marathon Oil in developing the Marathon Oil forecasted financial information include, but are not limited to: no acquisitions other than those that had been already announced; no balance sheet optimization; normal weather in the forward-looking periods; ongoing investments in Marathon Oil’s existing entities for maintenance, integrity and other capital expenditures; and no material fluctuations in interest rate assumptions over the forward-looking periods. The Marathon Oil forecasted financial information also reflects assumptions regarding the continuing nature of certain business decisions that, in reality, would be subject to change. The Marathon Oil forecasted financial information was based on information known to Marathon Oil management as of May 11, 2024.

Important factors that may affect actual results and cause the Marathon Oil forecasted financial information not to be achieved include, but are not limited to, changes in commodity prices and production growth rate from those described, risks and uncertainties relating to Marathon Oil’s business (including the ability to achieve strategic goals, objectives and targets), industry performance, the legal and regulatory environment, general business and economic conditions and other factors described in this proxy/statement prospectus or described or referenced in Marathon Oil’s filings with the SEC, including each of Marathon Oil’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, subsequent quarterly reports on Form 10-Q and current reports on Form 8-K. This information constitutes “forward-looking statements” and actual results may differ materially and adversely from those projected. For more information, see the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 37. In addition, the Marathon Oil forecasted financial information reflects assumptions as to certain business decisions that are subject to change and subjective judgment that is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. The Marathon Oil forecasted financial information does not reflect revised prospects for Marathon Oil’s or ConocoPhillips’ respective businesses, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the Marathon Oil forecasted financial information was prepared.

The Marathon Oil forecasted financial information was developed through Marathon Oil’s customary strategic planning and budgeting process utilizing Marathon Oil management’s best then available estimates and judgments at the time of its preparation. The Marathon Oil forecasted financial information was

67

developed on a standalone basis without giving effect to the merger, and therefore the Marathon Oil forecasted financial information does not give effect to the merger or any changes to the combined company’s operations or strategy that may be implemented after the effective time of the merger if the merger is completed, including potential cost synergies to be realized as a result of the merger, or to any costs incurred in connection with the merger. Furthermore, the Marathon Oil forecasted financial information does not take into account the effect of any failure of the merger to be completed and should not be viewed as accurate or continuing in that context.

Accordingly, there can be no assurance that the Marathon Oil forecasted financial information will be realized or that Marathon Oil’s future financial results will not vary materially from the Marathon Oil forecasted financial information. None of Marathon Oil, ConocoPhillips nor any of their respective affiliates, officers, directors, advisors or other representatives can give any assurance that actual results will not differ from the Marathon Oil forecasted financial information, and none of Marathon Oil, ConocoPhillips, nor any of their respective affiliates undertakes any obligation to update or otherwise revise or reconcile the Marathon Oil forecasted financial information to reflect circumstances existing or developments and events occurring after the date of the Marathon Oil forecasted financial information or that may occur in the future, even in the event that any or all of the assumptions underlying the Marathon Oil forecasted financial information are not realized or are shown to be inappropriate, including with respect to the accounting treatment of the merger under GAAP, or to reflect changes in general economic or industry conditions. Marathon Oil and ConocoPhillips do not intend to make available publicly any update or other revision to the Marathon Oil forecasted financial information, except as otherwise required by applicable law. None of Marathon Oil, ConocoPhillips nor any of their respective affiliates, officers, directors, advisors or other representatives has made or makes any representation to any Marathon Oil stockholder or any other person regarding the ultimate performance of Marathon Oil or ConocoPhillips compared to the information contained in the Marathon Oil forecasted financial information or that the Marathon Oil forecasted financial information will be achieved. The inclusion of the forecasted financial information herein should not be deemed an admission or representation by Marathon Oil, ConocoPhillips nor any of their respective advisors or other representatives or any other person that it is viewed as material information of Marathon Oil or ConocoPhillips, particularly in light of the inherent risks and uncertainties associated with such forecasts.

In light of the foregoing factors and considering that the special meeting will be held several months after the forecasted financial information was prepared, as well as the uncertainties inherent in the Marathon Oil forecasted financial information, Marathon Oil stockholders are cautioned not to place undue, if any, reliance on the information presented in this summary of the Marathon Oil forecasted financial information, and Marathon Oil and ConocoPhillips urge all Marathon Oil stockholders to review Marathon Oil’s most recent SEC filings for a description of Marathon Oil’s reported financial results and ConocoPhillips’ most recent SEC filings for a description of ConocoPhillips’ reported financial results. For additional information, see the section entitled “Where You Can Find More Information” beginning on page 157.

Unlevered free cash flow is defined as Adjusted EBITDAX less cash taxes, exploitations and exploration costs, capital expenditures and certain other operating expenses. This measure should not be considered as an alternative to any measure derived in accordance with GAAP. The unlevered free cash flow was

69

arithmetically derived from Marathon Oil management projections by Morgan Stanley and approved for Morgan Stanley’s use by Marathon Oil management.

2024E unlevered free cash flow represents only the projected values for the second, third and fourth quarters of fiscal year 2024, as utilized in the discounted cash flow analysis.

The unaudited forecasted financial numbers shown in the tables above are not measures that have a standardized meaning prescribed by GAAP and may not be comparable with similar measures presented by other issuers.

MARATHON OIL AND CONOCOPHILLIPS DO NOT INTEND TO UPDATE, CORRECT 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.

Regulatory Approvals

Completion of the merger is conditioned upon the receipt of certain governmental clearances or approvals, including the expiration or termination of any applicable waiting period, or any extension thereof, under the HSR Act. The process for obtaining the requisite regulatory approvals for the merger is ongoing.

Although ConocoPhillips and Marathon Oil currently believe they should be able to obtain all required regulatory approvals in a timely manner, the parties cannot be certain when or if they will obtain them or, if obtained, whether the approvals will contain terms, conditions or restrictions not currently contemplated that will be detrimental to ConocoPhillips after the completion of the merger.

The approval of an application for regulatory approval means only that the regulatory criteria for approval have been satisfied or waived. It does not mean that the approving regulatory authority has determined that the consideration to be received by holders of Marathon Oil common stock and/or the merger is fair to Marathon Oil stockholders. Regulatory approval does not constitute an endorsement or recommendation of the merger by any regulatory authority. The completion of the merger is subject to the receipt of antitrust clearance in the United States and any applicable waiting period, clearance or affirmative or deemed approval of any governmental entity or other condition with respect to certain non-U.S. antitrust approvals having expired or terminated, or been obtained or satisfied, as applicable.

U.S. Antitrust Filing

Under the HSR Act and the rules promulgated thereunder, the merger may not be completed unless certain waiting period requirements have expired or been terminated. The HSR Act provides that each party must file its respective HSR notification with the FTC and the DOJ. A transaction notifiable under the HSR Act may not be completed until the expiration of a 30-calendar-day waiting period following the parties’ filings of their respective HSR Act notification forms or the early termination of that waiting period. After the expiration of the initial waiting period (or the re-started initial waiting period), the DOJ or the FTC may issue a second request. If a second request is issued, the parties may not complete the merger until they substantially comply with the second request and observe a second 30-calendar-day waiting period, unless the waiting period is terminated earlier or extended by the parties.

On June 11, 2024, each of ConocoPhillips and Marathon Oil filed notification and report forms under the HSR Act with the FTC and the DOJ with respect to the merger. On July 11, 2024, ConocoPhillips and Marathon Oil each received a second request from the FTC in connection with the FTC’s review of the merger.

At any time before or after the expiration or termination of any applicable waiting period, or any extension thereof, under the HSR Act, or before or after the merger is completed, the DOJ or the FTC may take action under the antitrust laws in opposition to the merger, including seeking to enjoin completion of

70

the merger, to rescind the merger or to conditionally permit completion of the merger subject to regulatory concessions or conditions. In addition, U.S. state attorneys general could take action under the antitrust laws as they deem necessary or desirable in the public interest, including, without limitation, seeking to enjoin the completion of the merger or permitting completion subject to regulatory concessions or conditions. Private parties may also seek to take legal action under the antitrust laws under some circumstances.

Although neither ConocoPhillips nor Marathon Oil believes that the merger will violate applicable antitrust laws, there can be no assurance that a challenge to the merger on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful.

Other Regulatory Approvals

The Bundeskartellamt and certain other non-U.S. governmental authorities must approve the merger. On July 16, 2024, ConcocoPhillips and Marathon Oil received clearance on the merger from the Bundeskartellamt.

SEC Clearance of Registration Statement

The completion of the merger is conditioned on the registration statement of which this proxy statement/​prospectus forms a part being declared effective and the absence of any stop order or proceedings seeking a stop order.

NYSE Listing

Pursuant to the merger agreement, the shares of ConocoPhillips common stock to be issued in the merger must have been approved for listing on the NYSE, upon official notice of issuance.

Other Governmental Approvals

ConocoPhillips and Marathon Oil are not aware of any material governmental approvals that are required for completion of the merger other than those described above. If any such additional governmental approvals are required, ConocoPhillips and Marathon Oil will use their respective reasonable best efforts, subject to certain limitations, to obtain any such approvals from any governmental authority that are required under applicable law in order to consummate the transactions contemplated by the merger agreement. There can be no assurance, however, that any additional approvals will be obtained.

Efforts to Obtain Regulatory Approvals

ConocoPhillips and Marathon Oil have agreed in the merger agreement to use their respective reasonable best efforts, subject to certain limitations, to make the required governmental filings or obtain the required governmental authorizations, as the case may be, to complete the merger.

For additional information, see the sections entitled “The Merger Agreement — Reasonable Best Efforts” beginning on page 105 and “The Merger Agreement — HSR and Other Regulatory Approvals” beginning on page 99.

No Assurances of Obtaining Approvals; Timing

ConocoPhillips and Marathon Oil currently expect the merger to be completed in the fourth quarter of 2024, subject to receipt of Marathon Oil stockholder approval and of required regulatory approvals. Subject to certain conditions, either ConocoPhillips or Marathon Oil may terminate the merger agreement if the merger is not completed on or before the end date, as described under the section entitled “The Merger Agreement — Termination” beginning on page 109. There can be no assurances that any of the regulatory approvals described above will be obtained by the end date, or at all, and, if obtained, there can be no assurance as to the timing of such approvals, the ability to obtain such approvals on satisfactory terms or the absence of any litigation challenging such approval.

For additional information regarding regulatory approvals in connection with the merger, see the section entitled “The Merger Agreement — HSR and Other Regulatory Approvals” beginning on page 99.

71

Board of Directors and Management of ConocoPhillips Following the Completion of the Merger

Upon completion of the merger, the current directors and executive officers of ConocoPhillips are expected to continue in their current positions, other than as may be publicly announced by ConocoPhillips in the normal course.

Interests of Marathon Oil Directors and Executive Officers in the Merger

In considering the recommendation of the Marathon Oil board with respect to the proposals at the special meeting, Marathon Oil stockholders should be aware that the directors and executive officers of Marathon Oil may have interests in the merger that may be different from, or in addition to, the interests of Marathon Oil stockholders generally. The members of the Marathon Oil board were aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement, in approving the merger agreement and in determining to recommend that Marathon Oil stockholders approve the merger proposal.

Treatment of Marathon Oil Equity Awards

Marathon Oil Restricted Stock Unit Awards

At the effective time of the merger, each outstanding Marathon Oil RSU award, other than any such award granted to non-employee directors, granted under the Marathon Oil stock plan will be cancelled and converted into an award of restricted stock units in respect of ConocoPhillips common stock with substantially the same terms and conditions and covering that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (i) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger, multiplied by (ii) the exchange ratio. The award agreements governing Marathon Oil RSU awards granted to executive officers provide that the vesting of awards assumed by an acquirer in a change in control would accelerate in full upon the holder’s qualifying termination within 24 months following the change in control.

Marathon Oil Restricted Stock Unit and Deferred Stock Unit Awards Held by Non-Employee Directors

At the effective time of the merger, each outstanding Marathon Oil RSU award and each outstanding Marathon Oil DSU awards granted to a non-employee director of Marathon Oil pursuant to the Marathon Oil stock plan will immediately vest with respect to 100% of the shares of Marathon Oil common stock subject to such award, which shares will be converted into the right to receive (i) the merger consideration with respect to each such share and (ii) for RSUs, an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such Marathon Oil RSU award.

Marathon Oil Stock Option Awards

At the effective time of the merger, each outstanding Marathon Oil option award (all of which are vested) granted pursuant to the Marathon Oil stock plan will be canceled and converted into the right to receive a number of shares of ConocoPhillips common stock (rounded down to the nearest whole share) equal to the quotient of (i) the product of (A) the excess, if any, of the merger consideration value over the per share exercise price, multiplied by (B) the number of shares of Marathon Oil common stock subject to such Marathon Oil option award immediately prior to the effective time of the merger, divided by (ii) the ConocoPhillips common stock closing price. Any Marathon Oil option award that has an exercise price per share that is equal to or greater than the merger consideration value will be canceled for no consideration.

Marathon Oil Performance Unit Awards

At the effective time of the merger, each outstanding Marathon Oil performance unit award granted pursuant to the Marathon Oil stock plan will immediately vest and be converted into the right to receive (i) in the case of Marathon Oil performance unit awards that vest based on total shareholder return, (A) that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (x) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger reflecting the attainment of the applicable performance metrics at

72

the maximum level of performance (200% of target) multiplied by (y) the exchange ratio and (B) an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such award or (ii) in the case of Marathon Oil performance unit awards that vest based on free cash flow, an amount in cash reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by the average daily closing price of Marathon Oil common stock during the final 30 calendar days ending on the last trading day immediately preceding the closing date; provided, however, that if any values were banked under such award based on a price per share of Marathon Oil common stock that is greater than such average price, then the higher price shall be used for such portion of the award, plus any accrued but unpaid dividend equivalents with respect to such award.

Quantification of Equity Award Payments

For an estimate of the amounts that would be payable to each of Marathon Oil’s named executive officers on settlement of their unvested Marathon Oil equity awards, see the section entitled “— Merger-Related Compensation” beginning on page 75. The estimated amount that would be payable to Marathon Oil’s only executive officer who is not a named executive officer, Zach B. Dailey (Vice President, Controller and Chief Accounting Officer), in settlement of his 23,653 currently outstanding Marathon Oil RSU awards upon a qualifying termination of employment is $669,143 (including any associated dividend equivalent payments), and the executive officer who is not a named executive officer does not currently hold any outstanding Marathon Oil performance unit awards. The estimated aggregate amount that would be payable to Marathon Oil’s seven non-employee directors in settlement of their Marathon Oil RSU awards based on their 28,455 currently outstanding unvested awards is $808,122 (including any associated dividend equivalent payments). The amounts in this paragraph are determined using a per share price of Marathon Oil common stock of $28.29 (which is the average closing price of a share of Marathon Oil common stock over the first five business days following the first public announcement of the merger) and based on an assumed closing date of June 24, 2024.

Marathon Oil Corporation Officer Change in Control Severance Benefits Plan

Each of Marathon Oil’s executive officers are eligible under the Marathon Oil Corporation Officer Change in Control Severance Benefits Plan (the “CIC Severance Plan”), which provides for enhanced severance benefits in the event that, within 24 months following a change in control, the executive officer’s employment is terminated without “cause” or the executive officer resigns for “good reason” ​(both as defined in the CIC Severance Plan), which we refer to as a qualifying termination. The effective time of the merger will constitute a change in control for purposes of the CIC Severance Plan.

The CIC Severance Plan provides that, in the event of a qualifying termination, the executive officer will be entitled to:

•

a cash lump sum payment equal to three times the sum of (a) the executive officer’s annual base salary (as in effect immediately prior to the occurrence of the circumstances giving rise to the termination from employment or, if higher, immediately prior to the change in control) plus (b) the greater of (i) the target annual bonus opportunity for the year of termination from employment and (ii) the highest of the annual bonuses paid to the executive officer for each of the three years before the termination from employment or, if higher, for each of the three years before the change in control; and

•

a cash payment equal to 18 times the monthly Consolidated Omnibus Budget Reconciliation Act (“COBRA”) premium in effect as of the separation date for the level of coverage in which the executive officer participated immediately prior to the termination from employment.

In addition, pursuant to the CIC Severance Plan, any payments or benefits payable to the executive officer will be reduced to the extent that such payments or benefits would result in the imposition of excise taxes under Section 4999 of the Code, unless the executive officer would be better off on an after-tax basis receiving all such payments or benefits.

On February 29, 2024, Marathon Oil announced that Mr. Whitehead had informed Marathon Oil of his intention to retire from Marathon Oil effective July 1, 2024. On May 29, 2024, Marathon Oil announced that Marathon Oil and Mr. Whitehead agreed to delay his departure and Mr. Whitehead will remain an

73

Executive Vice President and Advisor to the CEO and will lead the transition planning team until the closing of the merger. In connection with his termination upon the closing date of the merger, Mr. Whitehead will be entitled to receive benefits pursuant to the CIC Severance Plan.

For an estimate of the value of the payments and benefits described above that would be payable to Marathon Oil’s named executive officers under the CIC Severance Plan upon a qualifying termination in connection with the merger, see the section entitled “— Merger-Related Compensation” beginning on page 75. The estimated cash severance amount that would be payable to Marathon Oil’s executive officer who is not a named executive officer under the CIC Severance Plan if the merger were to be completed and he was to experience a qualifying termination on June 24, 2024 is $1,885,651.

2024 Annual Cash Bonus

In connection with the merger, each employee of Marathon Oil (including each of Marathon Oil’s named executive officers) who, as of immediately prior to the closing (or, if earlier, as of the relevant payment date), is eligible for an annual cash bonus for calendar year 2024 and is employed by Marathon Oil or one of its subsidiaries on the payment date (or whose employment is involuntarily terminated by ConocoPhillips or one of its subsidiaries without “cause” or by the employee for “good reason”, in each case, following the closing but prior to the payment date) will be eligible to receive an annual bonus for 2024 in an amount equal to the amount payable based on maximum performance (which amount will be 200% of the amount payable upon target performance), subject to meeting individual performance expectations, based on eligible earnings, or, with respect to an employee whose employment was terminated during 2024, annualized eligible earnings, payable on the date Marathon Oil would normally pay annual cash bonuses for 2024 (or as soon as reasonably practicable following a qualifying termination for an employee whose employment is terminated before such date, subject to the execution of a general release of claims). For an estimate of the value of the payments that would be payable to Marathon Oil’s named executive officers for the annual bonus for 2024, see the section entitled “— Merger-Related Compensation” beginning on page 75. The estimated annual bonus for 2024 that would be payable to Marathon Oil’s executive officer who is not a named executive officer based on maximum performance and eligible earnings as described above is $337,397.

Retention Program

Under the merger agreement, Marathon Oil may establish a cash-based retention program in the aggregate amount of up to $60 million to promote retention and to incentivize efforts to consummate the merger and to ensure a successful and efficient integration process. Allocations from this program may be made to any employee of Marathon Oil (including the executive officers). Any allocation from this program to an executive officer will be determined by the compensation committee of the Marathon Oil board in consultation with the ConocoPhillips CEO and the terms of such awards will provide for vesting and payment no earlier than the closing date, subject to continued service with Marathon Oil through such date. As of the date of this proxy statement/prospectus, there are no agreements or arrangements regarding allocation of awards from the retention program to any of the executive officers.

Other Compensation Matters

In addition to the payments and benefits above, under the terms of the merger agreement, Marathon Oil may take certain compensation actions prior to the completion of the merger that will affect Marathon Oil’s directors and executive officers, although determinations related to such actions have not been made as of the date of this proxy statement/prospectus and the impact of such actions is not reflected in the amounts estimated above. Marathon Oil may take certain actions to mitigate any impact resulting from the application of Sections 280G and 4999 of the Code and to maximize the net after-tax proceeds by any individual subject to Section 4999 of the Code. After exhausting commercially reasonable mitigation strategies, Marathon Oil may enter into make-whole agreements with disqualified individuals to minimize any negative economic impact resulting from the application of Section 4999 of the Code providing for make-whole payments of up to $21 million in the aggregate. As of the date of this proxy statement/prospectus, Marathon Oil has not determined whether any such payments will be made. Any such compensation actions are within the sole discretion of Marathon Oil and are not subject to approval by ConocoPhillips.

74

Merger-Related Compensation

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation of each of Marathon Oil’s named executive officers, that is based on or otherwise relates to the merger and that will or may become payable to the named executive officers at the completion of the merger or on a qualifying termination of employment upon or following the date of the consummation of the merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section, we use such term to describe the merger-related compensation payable to the Marathon Oil named executive officers. The “golden parachute” compensation payable to these individuals is subject to a non-binding advisory vote of Marathon Oil stockholders. The “named executive officers” are Marathon Oil’s named executive officers as disclosed in Marathon Oil’s most recent annual proxy statement, plus Mr. Rob L. White (Chief Financial Officer).

The table below sets forth, for the purposes of this golden parachute disclosure, the amount of payments and benefits (on a pre-tax basis) that each of Marathon Oil’s named executive officers would receive based on the following: (i) the effective time of the merger occurs on June 24, 2024, (ii) each named executive officer experiences a qualifying termination on such date, (iii) the named executive officer’s base salary rate and annual target bonus remain unchanged from that in effect as of the date of this proxy statement/prospectus, (iv) the Marathon Oil stock options, restricted stock units, performance units and other awards outstanding as of the date hereof, (v) the closing price of a share of Marathon Oil common stock on the completion of the merger is $28.29 (which is the average closing price of a share of Marathon Oil common stock over the first five business days following the first public announcement of the merger) and (vi) each named executive officer has properly executed any required releases and complied with all requirements necessary in order to receive the payments and benefits. Some of the assumptions used in the table below are based upon information not currently available and, as a result, the actual amounts to be received by any of the individuals below may materially differ from the amounts set forth below. Further, the table below does not reflect any payments that may be made under any Section 280G make-whole agreements, which agreements have not been executed or amounts thereunder determined as of the date of this proxy statement/prospectus, or awards under the retention program, which have not been allocated to the executive officers as of the date of this proxy statement/prospectus. Additional detail regarding the named executive officers’ interests in the merger is provided in the section entitled “— Interests of Marathon Oil Directors and Executive Officers in the Merger” beginning on page 72.

The amount shown for each named executive officer consists of: (a) a lump sum cash severance equal to three times the sum of (i) the executive officer’s annual base salary plus (ii) the higher of the current year target annual bonus opportunity and the highest annual bonus paid to the executive officer in the three years preceding the change in control; and (b) the named executive officer’s annual bonus for the 2024 calendar year as described above, as set forth in more detail in the table below this footnote. The severance payment is considered to be a double-trigger payment, which means that both a change in control, such as the merger, and a qualifying termination of employment must occur prior to any payment being provided to the named executive officer. The 2024 annual bonus is payable to the executive officer subject to continued employment through the payment date or, in the event of an involuntary termination by ConocoPhillips or one of its subsidiaries without “cause” or by the executive officer for “good reason,” in each case, following the closing but prior to the payment date, the date of the

75

executive officer’s termination of employment, subject to the executive’s execution of a general release of claims (which accelerated payment is considered to be a double-trigger payment).

The amounts shown in this column represent 18 times the monthly COBRA premium in effect as of the date of this proxy statement/prospectus for the level of coverage in which the executive officer participates as of such date.

Potential Employment Arrangements with ConocoPhillips

Any of Marathon Oil’s executive officers who become officers or employees or who otherwise are retained to provide services to ConocoPhillips or its affiliates may, prior to, on or following the effective time of the merger, enter into new compensation arrangements with ConocoPhillips or its affiliates. As of the date of this proxy statement/prospectus, no new individualized compensation arrangements between Marathon Oil’s executive officers and ConocoPhillips or its affiliates have been established.

Indemnification and Insurance

Under the merger agreement, the surviving corporation is required to, and ConocoPhillips is required to cause the surviving corporation to, do the following:

•

for six years after the effective time of the merger, to the fullest extent permitted by applicable law, indemnify, defend and hold harmless (and advance expenses in connection therewith, subject to a customary undertaking from the applicable indemnified person to return such advances if it is determined by the final adjudication of a court of law that the indemnified person is not entitled to indemnification under the merger agreement) the present and former directors, officers, employees, fiduciaries and agents of the Marathon Oil and its subsidiaries, and any individuals serving in such capacity at or with respect to other persons at Marathon Oil’s and its subsidiaries’ request (each of

76

whom we refer to as an “indemnified person”) from and against any losses, claims, damages, liabilities, costs, expenses (including attorneys’ fees), judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect thereof) in respect of the indemnified persons having served in such capacity at or prior to the effective time of the merger, in each case, to the fullest extent permitted by the DGCL or provided under the organizational documents of Marathon Oil and its subsidiaries in effect as of the date of the merger agreement;

•

if any indemnified person is made party to any proceeding arising out of or relating to matters that would be indemnifiable pursuant to the foregoing bullet, advance fees, costs and expenses (including attorneys’ fees and disbursements) as incurred by such indemnified person in connection with and prior to the final disposition of such claim, action, suit, proceeding or investigation in each case to the extent Marathon Oil is required to do so and on the same terms as provided in the organizational documents of Marathon Oil and its subsidiaries in effect as of the date of the merger agreement; provided that, any indemnified person wishing to claim indemnification or advancement of expenses, upon learning of any such proceeding, must notify the surviving corporation (but the failure to notify shall not relieve the surviving corporation from the foregoing obligations that it may have, except to the extent such failure materially prejudices such party’s position with respect to such claims);

•

for six years after the effective time of the merger, maintain in effect provisions in the organizations documents of the surviving corporation and its subsidiaries (or in such documents of any successor to the business thereof) regarding elimination of liability of directors and officers, indemnification of officers, directors, employees, fiduciaries and agents and advancement of fees, costs and expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence as of the date of the merger agreement; and

•

for six years after the effective time of the merger, honor and comply with the obligations set forth in any indemnification agreements with indemnified persons set forth in Marathon Oil’s disclosure letter, and not amend, repeal or otherwise modify such agreement in a manner materially adverse to such indemnified person.

ConocoPhillips has agreed to guarantee and stand surety for, and cause the surviving corporation to honor its obligations under, the first three bullets of the foregoing paragraph.

Additionally, prior to the effective time of the merger, Marathon Oil may, or if its unable to do so, ConocoPhillips must cause the surviving corporation, as of the effective time of the merger to, obtain and fully pay the premium for the non-cancellable extension of the directors’ and officers’ liability coverage of Marathon Oil’s existing directors’ and officers’ insurance policies and Marathon Oil’s existing fiduciary liability insurance policies, each with a reporting/discovery period of at least six years following the effective time of the merger, from an insurance carrier with the same or better credit rating as Marathon Oil’s current insurance carrier and having terms and conditions no less favorable than those provided under Marathon Oil’s existing policies. In no event will the aggregate cost of the directors’ and officers’ liability insurance exceed during the tail period 350% of the current aggregate annual premium paid by Marathon Oil for such purpose. If the cost of such insurance coverage exceeds such amount, the surviving corporation has agreed to obtain a policy with the greatest coverage available for a cost not exceeding such amount.

For additional information, see the section entitled “The Merger Agreement — Indemnification; Directors’ and Officers’ Insurance” beginning on page 103.

Listing of ConocoPhillips Shares; Delisting and Deregistration of Marathon Oil Shares

If the merger is completed, the shares of ConocoPhillips common stock to be issued in the merger will be listed for trading on the NYSE, shares of Marathon Oil common stock will be delisted from the NYSE and deregistered under the Exchange Act, and Marathon Oil will no longer be required to file periodic reports with the SEC pursuant to the Exchange Act.

Accounting Treatment of the Merger

ConocoPhillips and Marathon Oil prepare their respective financial statements in accordance with GAAP. The accounting guidance for business combinations requires the use of the acquisition method of

77

accounting for the merger, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any. ConocoPhillips will be treated as the acquirer for accounting purposes.

Treatment of Indebtedness

As of March 31, 2024, Marathon Oil had $7 million outstanding under its revolving credit facility. Completion of the merger would give lenders thereunder the right to require prepayment of their loans under the terms of the Marathon Oil revolving credit facility. Accordingly, ConocoPhillips expects the facility to be terminated in connection with consummation of the merger.

As of March 31, 2024, Marathon Oil had $450 million outstanding under its commercial paper program. ConocoPhillips expects the commercial paper program to be terminated in connection with consummation of the merger.

As of March 31, 2024, Marathon Oil had outstanding (i) $1 billion in aggregate principal amount of 4.400% senior notes due 2027, (ii) $600 million in aggregate principal amount of 5.300% senior notes due 2029, (iii) $550 million in aggregate principal amount of 6.800% senior notes due 2032, (iv) $600 million in aggregate principal amount of 5.700% senior notes due 2034, (v) $750 million in aggregate principal amount of 6.600% senior notes due 2037 and (vi) $500 million in aggregate principal amount of 5.200% senior notes due 2045. The consummation of the transaction is not expected to provide the holders of the Marathon Oil Notes with any rights.

As of March 31, 2024, Marathon Oil had outstanding $1 billion of the Marathon Municipal Bonds. The consummation of the transaction is not expected to provide the holders of the Marathon Municipal Bonds with any rights.

ConocoPhillips expects that the Marathon Oil Notes and the Marathon Municipal Bonds will remain outstanding or that it will commence exchange offers and consent solicitations in connection therewith. If ConocoPhillips commences exchange offers and consent solicitations, such action will be set forth in separate documentation and subject to the terms and conditions thereof.

This proxy statement/prospectus does not constitute an offer to sell or the solicitation of an offer to buy any debt securities of ConocoPhillips or Marathon Oil.

Litigation Relating to the Merger

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements like the merger agreement. Although Marathon Oil and ConocoPhillips are not aware of any pending or threatened lawsuits relating to the transactions contemplated by the merger agreement as of the date of this proxy statement/prospectus, lawsuits arising out of the transactions contemplated by the merger agreement could be filed in the future. As of the date of this proxy statement/prospectus, Marathon Oil has received demand letters from purported stockholders of Marathon Oil alleging deficiencies and/or omissions in the preliminary proxy statement/​prospectus forming part of this registration statement. The demand letters seek additional disclosures to remedy these purported deficiencies. Marathon Oil and ConocoPhillips believe that the allegations in these letters are without merit. For additional information, see “Risk Factors — Lawsuits may be filed against Marathon Oil, ConocoPhillips, Merger Sub and the members of the Marathon Oil and ConocoPhillips boards in connection with the merger. An adverse ruling in any such lawsuit could result in an injunction preventing the completion of the merger and/or substantial costs to ConocoPhillips and Marathon Oil.”

THE MERGER AGREEMENT

This section describes the material terms of the merger agreement, which was executed on May 28, 2024. The description of the merger agreement in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus and is incorporated by reference herein in its entirety. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. You are encouraged to read the merger agreement carefully and in its entirety because it is the legal document that governs the merger.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary are included solely to provide you with information regarding the terms of the merger agreement. Factual disclosures about ConocoPhillips, Marathon Oil or any of their respective subsidiaries or affiliates contained in this proxy statement/prospectus or in ConocoPhillips’ or Marathon Oil’s public reports filed with the SEC may supplement, update or modify the factual disclosures about ConocoPhillips or Marathon Oil, as applicable, contained in the merger agreement. The representations, warranties and covenants made in the merger agreement by ConocoPhillips, Marathon Oil and Merger Sub were made solely for the purposes of the merger agreement and as of specific dates and were qualified and subject to important limitations agreed to by ConocoPhillips, Marathon Oil and Merger Sub in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purposes of establishing the circumstances in which a party to the merger agreement may have the right not to complete the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC, and in some cases were qualified by the matters contained in the respective disclosure letters that ConocoPhillips and Marathon Oil delivered to each other in connection with the merger agreement, which disclosures were not reflected in the merger agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since May 28, 2024. You should not rely on the merger agreement representations, warranties, covenants or any descriptions thereof as characterizations of the actual state of facts of ConocoPhillips, Marathon Oil and Merger Sub or any of their respective subsidiaries or affiliates.

Effect of the Merger on Capital Stock; Merger Consideration

At the effective time of the merger, by virtue of the merger and without any action on the part of ConocoPhillips, Merger Sub, Marathon Oil or any holder of any securities of ConocoPhillips, Merger Sub or Marathon Oil:

•

each share of capital stock of Merger Sub issued and outstanding immediately prior to the effective time of the merger will be converted into and will represent one fully paid and nonassessable share of common stock of the surviving corporation;

•

each share of Marathon Oil common stock issued and outstanding immediately prior to the effective time of the merger (excluding any excluded shares or converted shares (as such terms are defined below)) will be converted into the right to receive from ConocoPhillips 0.255 shares of fully paid and nonassessable shares of ConocoPhillips common stock, subject to adjustment as specified in the merger agreement;

•

all such shares of Marathon Oil common stock, when so converted, will cease to be outstanding and will automatically be canceled and cease to exist. Each holder of a share of Marathon Oil common stock that was outstanding immediately prior to the effective time of the merger (excluding any excluded shares or converted shares) will cease to have any rights with respect thereto, except the right to receive the merger consideration, any dividends or other distributions paid with respect to such shares following the effective time and any cash to be paid in lieu of any fractional shares of ConocoPhillips common stock;

80

•

all shares of Marathon Oil common stock held by Marathon Oil as treasury shares or by ConocoPhillips or Merger Sub immediately prior to the effective time of the merger and, in each case, not held on behalf of third parties (which we refer to collectively as “excluded shares”) will automatically be canceled and cease to exist as of the effective time of the merger, and no consideration will be delivered in exchange for excluded shares; and

•

each share of Marathon Oil common stock that is owned by any direct or indirect subsidiary of Marathon Oil or ConocoPhillips (other than Merger Sub) (which we refer to collectively as “converted shares”) will automatically be converted into a number of fully paid and nonassessable shares of ConocoPhillips common stock equal to 0.255, subject to adjustment as described below.

In the event of any change in the number of shares of Marathon Oil or ConocoPhillips common stock or securities convertible or exchangeable into or exercisable for shares of Marathon Oil or ConocoPhillips common stock (in each case issued and outstanding after May 28, 2024 and before the effective time) by reason of any stock split, reverse stock split, stock dividend, subdivision, reclassification, recapitalization, combination, exchange of shares or the like, the number of shares of ConocoPhillips common stock issuable in respect of each share of Marathon Oil common stock will be equitably adjusted to reflect the effect of such change.

Treatment of Marathon Oil Equity Awards in the Merger

Marathon Oil Restricted Stock Unit Awards

At the effective time of the merger, each outstanding Marathon Oil RSU award, other than any such award granted to non-employee directors, granted under the Marathon Oil stock plan will be cancelled and converted into an award of restricted stock units in respect of ConocoPhillips common stock with substantially the same terms and conditions and covering that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (i) the number of shares of Marathon Oil common stock subject to such award immediately prior to the effective time of the merger, multiplied by (ii) the exchange ratio.

Marathon Oil Restricted Stock Unit and Deferred Stock Unit Awards Held by Non-Employee Directors

At the effective time of the merger, each outstanding Marathon Oil RSU award and each outstanding Marathon Oil DSU awards granted to a non-employee director of Marathon Oil pursuant to the Marathon Oil stock plan will immediately vest with respect to 100% of the shares of Marathon Oil common stock subject to such award, which shares will be converted into the right to receive (i) the merger consideration with respect to each such share and (ii) for RSUs, an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such Marathon Oil RSU award.

Marathon Oil Stock Option Awards

At the effective time of the merger, each outstanding and vested Marathon Oil option awards granted pursuant to the Marathon Oil stock plan will be canceled and converted into the right to receive a number of shares of ConocoPhillips common stock (rounded down to the nearest whole share) equal to the quotient of (i) the product of (A) the excess, if any, of the merger consideration value over the per share exercise price, multiplied by (B) the number of shares of Marathon Oil common stock subject to such Marathon Oil option award immediately prior to the effective time of the merger, divided by (ii) the ConocoPhillips common stock closing price. Any Marathon Oil option award that has an exercise price per share that is equal to or greater than the merger consideration value will be canceled for no consideration.

Marathon Oil Performance Unit Awards

At the effective time of the merger, each outstanding Marathon Oil performance unit award granted pursuant to the Marathon Oil stock plan will immediately vest and be converted into the right to receive (i) in the case of Marathon Oil performance unit awards that vest based on total shareholder return, (A) that number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (x) the number of shares of Marathon Oil common stock subject to such award immediately

81

prior to the effective time of the merger reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by (y) the exchange ratio and (B) an amount in cash equal to any accrued but unpaid dividend equivalents with respect to such award or (ii) in the case of Marathon Oil performance unit awards that vest based on free cash flow, an amount in cash reflecting the attainment of the applicable performance metrics at the maximum level of performance (200% of target) multiplied by the average daily closing price of Marathon Oil common stock during the final 30 calendar days ending on the last trading day immediately preceding the closing date; provided, however, that if any values were banked under such award based on a price per share of Marathon Oil common stock that is greater than such average price, then the higher price shall be used for such portion of the award, plus any accrued but unpaid dividend equivalents with respect to such award.

Payment for Securities; Exchange

Prior to the effective time of the merger, ConocoPhillips has agreed to enter into an agreement with an exchange agent for the holders of Marathon Oil common stock in connection with the merger (which we refer to as the “exchange agent”).

No Interest

No interest will be paid or accrued on any amount payable for shares of Marathon Oil common stock eligible to receive the merger consideration pursuant to the merger agreement.

At the effective time of the merger, the stock transfer books of the surviving corporation will be closed immediately, and there will be no further registration of transfers on the stock transfer books of the surviving corporation of the shares of Marathon Oil common stock that were outstanding immediately prior to the effective time of the merger. If, after the effective time of the merger, Marathon Oil common stock certificates are presented to the surviving corporation for any reason, they will be canceled and exchanged for the merger consideration, any cash in lieu of any fractional shares of ConocoPhillips common stock and dividends and other distributions on the shares of ConocoPhillips common stock issuable as merger consideration.

If any Marathon Oil common stock certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Marathon Oil common stock certificate to be lost, stolen or destroyed and, if reasonably required by the surviving corporation, the posting by such person of 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 Marathon Oil common stock certificate, the exchange agent will issue in exchange for such lost, stolen or destroyed Marathon Oil common stock certificate the merger consideration, any cash in lieu of any fractional shares of ConocoPhillips common stock and dividends and other distributions on the shares of ConocoPhillips common stock issuable as merger consideration.

No Fractional Shares of ConocoPhillips Common Stock

No Marathon Oil common stock certificates or scrip or shares representing fractional shares of ConocoPhillips common stock will be issued upon the exchange of eligible shares of Marathon Oil common stock, and such fractional share interests will not entitle the owner of such fractional share interests to vote or to have any rights of a stockholder of ConocoPhillips or a holder of shares of ConocoPhillips common stock. Each holder of shares exchanged pursuant to the merger who would otherwise have been entitled to receive a fraction of a share of ConocoPhillips common stock (after taking into account all certificates and book-entry shares held by such holder) will receive, in lieu of such fractional shares of ConocoPhillips common stock, cash (without interest) in an amount equal to the product of (i) such fractional part of a share of ConocoPhillips common stock multiplied by (ii) the ConocoPhillips common stock closing price.

83

(provided that, except as otherwise required by law, the parties have agreed that the merger consideration payable or deliverable pursuant to the merger agreement shall not be subject to withholding under Section 1445 of the Code or the Treasury regulations promulgated thereunder). ConocoPhillips, Merger Sub, the surviving corporation and the exchange agent, as the case may be, will cooperate in good faith to minimize any such deduction or withholding. To the extent such amounts are deducted or withheld and paid over to the appropriate taxing authority by ConocoPhillips, Merger Sub, the surviving corporation or the exchange agent, as the case may be, 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.

Interim Operations of ConocoPhillips

ConocoPhillips has agreed that, subject to certain exceptions set forth in the merger agreement, the disclosure letter ConocoPhillips delivered to Marathon Oil in connection with the merger agreement, any actions required by applicable law, the rules and regulations of the NYSE, or otherwise consented to by Marathon Oil in writing (which consent will not be unreasonably withheld, delayed or conditioned) until the earlier of the effective time of the merger and the termination of the merger agreement pursuant to the merger agreement, it will, and will cause each of its subsidiaries to:

•

use reasonable best efforts to conduct its business in the ordinary course; and

•

use commercially reasonable efforts to preserve substantially intact its present material business organization, goodwill and assets and preserve its existing relationships with governmental entities and its material customers, suppliers, licensors, licensees, distributors, lessors and others having material business dealings with ConocoPhillips.

Notwithstanding the foregoing, ConocoPhillips and its subsidiaries may take commercially reasonable actions outside of the ordinary course in response to emergency conditions that present, or are reasonably likely to present, a significant risk of imminent harm to human health, any material property or asset of ConocoPhillips, its subsidiaries or the environment; provided that, ConocoPhillips must promptly as reasonably practicable inform Marathon Oil of any such condition and any such actions taken in response thereto.

In addition, ConocoPhillips has further agreed that, subject to certain exceptions set forth in the merger agreement, the disclosure letter ConocoPhillips delivered to Marathon Oil in connection with the merger agreement, required by applicable law, the rules and regulations of the NYSE, or otherwise consented to by Marathon Oil in writing (which consent will not be unreasonably withheld, delayed or conditioned), until the earlier of the effective time of the merger and the termination of the merger agreement, ConocoPhillips will not:

91

and corresponding dividend equivalents in respect of equity awards payable by ConocoPhillips, together with increases that are materially consistent with past practice;

•

amend or propose to amend ConocoPhillips’ organizational documents (other than in immaterial respects) in a manner that would prevent, materially delay or materially impair the ability of the parties to consummate the transactions contemplated by the merger agreement or otherwise materially and adversely affect the consummation of the transactions contemplated by the merger agreement, or be materially adverse to Marathon Oil’s stockholders (as compared to other stockholders of ConocoPhillips);

•

adopt a plan or announce an intention to adopt a plan of complete or partial liquidation or dissolution of ConocoPhillips; or

•

agree to take any action described above.

No Solicitation; Changes of Recommendation

No Solicitation

From and after May 28, 2024, Marathon Oil, its subsidiaries and their respective officers and directors must, and must use their reasonable best efforts to cause the other representatives of Marathon Oil and its subsidiaries to, immediately cease, and cause to be terminated, any discussion or negotiations ongoing with any third party with respect to any inquiry, proposal or offer that constitutes, or could reasonably be expected to lead to, a “competing proposal” ​(as defined below). Marathon Oil has agreed that by May 29, 2024, Marathon Oil will have delivered written notice to each third party that has received non-public information regarding Marathon Oil within the twelve months prior to May 28, 2024 pursuant to a confidentiality agreement with Marathon Oil for purposes of evaluating any transaction that could be a competing proposal and for whom no similar notice has been delivered prior to May 28, 2024 requesting the prompt return or destruction of all confidential information concerning Marathon Oil and its subsidiaries, and must terminate any data access related to any potential competing proposal previously granted to such third parties.

From and after May 28, 2024, Marathon Oil, its subsidiaries and their respective officers and directors may not, and must use their reasonable best efforts to cause the other representatives of Marathon Oil and its subsidiaries not to, directly or indirectly:

•

initiate, solicit, propose, knowingly encourage, or knowingly facilitate any inquiry or the making of any proposal or offer that constitutes, or could reasonably be expected to result in, a competing proposal;

•

engage in, continue or otherwise participate in any discussions with any person with respect to, or negotiations with any person with respect to, relating to, or in furtherance of a competing proposal or any inquiry, proposal or offer that could reasonably be expected to lead to a competing proposal;

•

furnish any information regarding Marathon Oil or its subsidiaries, or access to the properties, assets or employees of Marathon Oil or its subsidiaries, to any person in connection with or in response to any competing proposal or any inquiry, proposal or offer that could reasonably be expected to lead to a competing proposal;

•

enter into any letter of intent or agreement in principle, or other agreement providing for a competing proposal (other than certain confidentiality agreements entered into as permitted by the merger agreement); or

•

submit any proposal for a competing transaction to the vote of Marathon Oil stockholders.

Notwithstanding the above restrictions, Marathon Oil or any of its representatives may, in response to an inquiry or proposal from a third party, inform a third party or its representative of the “no solicitation” obligations described above (without conveying, requesting or attempting to gather any other information except as otherwise specifically permitted under the merger agreement).

From and after May 28, 2024, Marathon Oil has agreed to promptly (and in any event within 24 hours) notify ConocoPhillips of the receipt by Marathon Oil (directly or indirectly) of any competing proposal or

92

any expression of interest, inquiry, proposal or offer with respect to, or that could reasonably be expected to lead to, a competing proposal made on or after May 28, 2024, any request for information or data relating to Marathon Oil or any of its subsidiaries made by any person in connection with a competing proposal or any request for discussions or negotiations with Marathon Oil or a representative of Marathon Oil relating to, or that could reasonably be expected to lead to, a competing proposal (including the identity of such person), and Marathon Oil will provide to ConocoPhillips promptly (and in any event within 24 hours) (i) a copy of any such expression of interest, inquiry, proposal or offer made in writing provided to Marathon Oil or any of its subsidiaries or (ii) any such expression of interest, inquiry, proposal or offer that is not (or any portion thereof is not) made in writing, a written summary of the material financial and other terms thereof. Thereafter Marathon Oil has agreed to (i) keep ConocoPhillips reasonably informed, on a prompt basis (and in any event within 24 hours), of any material development regarding the status or terms of any such expressions of interest, inquiries, proposals or offers (including any amendments thereto) or material requests and will promptly (and in any event within 24 hours) apprise ConocoPhillips of the status of any such discussions or negotiations and (ii) provide to ConocoPhillips as soon as practicable after receipt or delivery thereof (and in any event within 24 hours) copies of all material written correspondence and other material written materials provided to Marathon Oil or its representatives from any person. Marathon Oil has agreed to notify ConocoPhillips if Marathon Oil determines to begin providing information or to engage in discussions or negotiations concerning a competing proposal, prior to providing any such information or engaging in any such discussions or negotiations.

No Solicitation Exceptions

Prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, Marathon Oil and its representatives may engage in the activities described in the second and third bullets in the second paragraph of the section directly above with any person if (i) Marathon Oil receives a bona fide written competing proposal from such person that was not solicited at any time after May 28, 2024; and (ii) such competing proposal did not arise from a material breach of the obligations described in “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation”; provided, however, that:

•

no information that is prohibited from being furnished pursuant to the “no solicitation” obligations described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation” beginning on page 92 may be furnished until Marathon Oil receives an executed confidentiality agreement, subject to certain conditions, including that limitations in such confidentiality agreement on the use and disclosure of non-public information furnished to such person are no less favorable in all material respects to Marathon Oil than the terms of the Confidentiality Agreement, dated May 10, 2024, between ConocoPhillips and Marathon Oil, as determined by the Marathon Oil board in good faith after consultation with its legal counsel;

•

any non-public information furnished to such person will have previously been made available to ConocoPhillips or is made available to ConocoPhillips prior to or concurrently with the time such information is made available to such person (or in the case of oral non-public information only, promptly (and in any event within 24 hours) after);

•

prior to taking any such actions, the Marathon Oil board or any committee of the Marathon Oil board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such competing proposal is, or would reasonably be expected to lead to, a superior proposal; and

•

prior to taking any such actions, the Marathon Oil board determines in good faith after consultation with its outside legal counsel that failure to take such action would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law.

Restrictions on Changes of Recommendation

Subject to certain exceptions described below, the Marathon Oil board, including any committee of the Marathon Oil board, may not:

•

withhold, withdraw, qualify or modify, or publicly propose or announce any intention to withhold, withdraw, qualify or modify, in a manner adverse to ConocoPhillips or Merger Sub, its recommendation that Marathon Oil stockholders approve the merger proposal;

93

•

fail to include its recommendation that Marathon Oil stockholders approve the merger proposal in this proxy statement/prospectus;

•

approve, endorse or recommend, or publicly propose or announce any intention to approve, endorse or recommend, any competing proposal;

•

publicly declare advisable or publicly propose to enter into, any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement (other than certain confidentiality agreements) relating to a competing proposal;

•

in the case of a competing proposal that is structured as a tender offer or exchange offer pursuant to Rule 14d-2 under the Exchange Act for outstanding shares of Marathon Oil common stock (other than by ConocoPhillips or an affiliate of ConocoPhillips), fail to recommend, in a Solicitation/​Recommendation Statement on Schedule 14D-9, against acceptance of such tender offer or exchange offer by its stockholders on or prior to the earlier of (i) three business days prior to the date of the special meeting (or promptly after commencement of such tender offer or exchange offer if commenced on or after the third business day prior to the date of the special meeting) or (ii) 10 business days (as such term is used in Rule 14d-9 of the Exchange Act) after commencement of such tender offer or exchange offer;

•

if a competing proposal will have been publicly announced or disclosed (other than pursuant to the bullet directly above), fail to publicly reaffirm its recommendation that Marathon Oil stockholders approve the merger proposal on or prior to the earlier of (i) five business days after ConocoPhillips so requests in writing or (ii) three business days prior to the date of the special meeting (or promptly after announcement or disclosure of such competing proposal if announced or disclosed on or after the third business day prior to the date of the special meeting); or

•

cause or permit Marathon Oil or any of its subsidiaries to enter into a letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement (other than certain confidentiality agreements) relating to a competing proposal.

We refer to the taking of any of the actions described in the seven bullets directly above as a “recommendation change.”

Permitted Changes of Recommendation and Termination of Merger Agreement in Connection with a Superior Proposal

Prior to, but not after, the merger proposal has been approved by Marathon Oil stockholders, in response to a bona fide written competing proposal from a third party that was not solicited at any time following May 28, 2024 and did not arise from a material breach of the obligations described above and in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation — No Solicitation” beginning on page 92 if the Marathon Oil board so chooses, the Marathon Oil board may effect a recommendation change (other than of the type described in bullet six in the section immediately above) or terminate the merger agreement to enter into a definitive agreement with respect to such proposal, provided, however, that such a change of recommendation or termination of the merger agreement, as applicable, may not be made unless and until:

•

the Marathon Oil board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such competing proposal is a superior proposal;

•

the Marathon Oil board determines in good faith, after consultation with its outside legal counsel, that failure to effect a recommendation change in response to such superior proposal or terminate the merger agreement to enter into a definitive agreement with respect to such superior proposal would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law;

•

Marathon Oil provides ConocoPhillips written notice of such proposed action and the basis of such proposed action five business days in advance, which notice will set forth in writing that the

94

Marathon Oil board intends to consider whether to take such action and include a copy of the available proposed competing proposal and any applicable transaction and financing documents;

•

after giving such notice and prior to effecting such recommendation change or terminating the merger agreement pursuant to entering into a definitive agreement with respect to such proposal, Marathon Oil negotiates (and causes its officers, employees, financial advisor and outside legal counsel to negotiate) in good faith with ConocoPhillips (to the extent ConocoPhillips wishes to negotiate) to make such adjustments or revisions to the terms of the merger agreement as would permit the Marathon Oil board not to effect a recommendation change or terminate the merger agreement; and

•

at the end of the five-business-day period, prior to taking action to effect a recommendation change or terminating the merger agreement to enter into a definitive agreement with respect to such proposal, the Marathon Oil board takes into account any adjustments or revisions to the terms of the merger agreement proposed by ConocoPhillips in writing and any other information offered by ConocoPhillips in response to the notice, and determines in good faith, after consultation with its financial advisors and outside legal counsel, that the competing proposal remains a superior proposal and that the failure to effect a recommendation change in response to such superior proposal, or terminate the merger agreement to enter into a definitive agreement with respect to such superior proposal, as applicable, would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law.

In the event of any material amendment or material modification to any superior proposal, Marathon Oil will be required to deliver a new written notice to ConocoPhillips and to comply with the foregoing requirements with respect to such new written notice, except that the advance written notice obligation will be reduced to three business days. Any amendment or modification to the economic terms of any such superior proposal will be deemed material for the purposes of the foregoing sentence.

Permitted Changes of Recommendation in Connection with Intervening Events

Prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, in response to an intervening event that occurs or arises after May 28, 2024 and that did not arise from or in connection with a breach of the merger agreement by Marathon Oil, Marathon Oil may, if the Marathon Oil board so chooses, effect a recommendation change (but may not terminate the merger agreement) if:

•

the Marathon Oil board determines in good faith after consultation with its financial advisors and outside legal counsel that an intervening event has occurred;

•

the Marathon Oil board determines in good faith, after consultation with its outside legal counsel, that failure to effect a recommendation change in response to such intervening event would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law;

•

Marathon Oil provides ConocoPhillips written notice of such proposed action and the basis of such proposed action five business days in advance, which notice will set forth in writing that the Marathon Oil board intends to consider whether to take such action and includes a reasonably detailed description of the facts and circumstances of the intervening event;

•

after giving such notice and prior to effecting such recommendation change, Marathon Oil negotiates (and causes its officers, employees, financial advisor and outside legal counsel to negotiate) in good faith with ConocoPhillips (to the extent ConocoPhillips wishes to negotiate) to make such adjustments or revisions to the terms of the merger agreement as would permit the Marathon Oil board not to effect a recommendation change in response thereto; and

•

at the end of the five-business-day period, prior to taking action to effect a recommendation change, the Marathon Oil board takes into account any adjustments or revisions to the terms of the agreement proposed by ConocoPhillips in writing and any other information offered by ConocoPhillips in response to the notice, and determines in good faith, after consultation with its financial advisors and outside legal counsel, that the failure to effect a recommendation change in response to such intervening event would be inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law.

95

In the event of any material changes regarding any intervening event, Marathon Oil will be required to deliver a new written notice to ConocoPhillips and to comply with the foregoing requirements with respect to such new written notice, except that the advance written notice obligation will be reduced to three business days.

An “intervening event” is a material development or change in circumstance that occurs or arises after May 28, 2024 that was not known to or reasonably foreseeable by the Marathon Oil board as of May 28, 2024 (or, if known or reasonably foreseeable, the magnitude or material consequences of which were not known or reasonably foreseeable by the Marathon Oil board as of May 28, 2024); except that in no event will (i) the receipt, existence or terms of an actual or possible competing proposal or superior proposal, (ii) any effect relating to ConocoPhillips or any of its subsidiaries that does not amount to a material adverse effect, individually or in the aggregate, (iii) any change, in and of itself, in the price or trading volume of shares of Marathon Oil common stock or ConocoPhillips common stock (it being understood that the underlying facts giving rise or contributing to such change may be taken into account in determining whether there has been an intervening event, to the extent otherwise permitted by this definition), (iv) the fact that Marathon Oil or any of its subsidiaries exceeds (or fails to meet) internal or published projections or guidance or any matter relating thereto or of consequence thereof (it being understood that the underlying facts giving rise or contributing to such change may be taken into account in determining whether there has been an intervening event, to the extent otherwise permitted by this definition) or (v) conditions (or changes in such conditions) in the oil and gas exploration and production industry (including changes in commodity prices, general market prices and political or regulatory changes affecting the industry or any changes in applicable law), constitute an intervening event.

Standstill Arrangements

From May 28, 2024, and continuing until the earlier of the effective time of the merger and the termination of the merger agreement, Marathon Oil has agreed not to (and it will cause its subsidiaries not to) terminate, amend, modify or waive any provision of any confidentiality, “standstill” or similar agreement to which it or any of its subsidiaries is a party. However, prior to, but not after, the time the merger proposal has been approved by Marathon Oil stockholders, if, in response to an unsolicited request from a third party to waive any “standstill” or similar provision, the Marathon Oil board determines in good faith, after consultation with its outside legal counsel that the failure to take such action would be inconsistent with its fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law, Marathon Oil may waive any such “standstill” or similar provision solely to the extent necessary to permit a third party to make a competing proposal, on a confidential basis, to the Marathon Oil board and communicate such waiver to the applicable third party. Marathon Oil must advise ConocoPhillips at least two business days prior to taking such action. Marathon Oil has represented and warranted to ConocoPhillips that it has not taken any action that (i) would be prohibited by this paragraph or (ii) but for the ability to avoid actions inconsistent with the fiduciary duties owed by the Marathon Oil board to the stockholders of Marathon Oil under applicable law, would have been prohibited by this paragraph during the 30 days prior to May 28, 2024.

Certain Permitted Disclosure

The Marathon Oil board may, after consultation with its outside legal counsel, make such disclosures as the Marathon Oil board determines in good faith are necessary to comply with Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or other disclosure required to be made in this proxy statement/​prospectus by applicable U.S. federal securities laws. If such disclosure has the effect of withdrawing or adversely modifying its recommendation that Marathon Oil stockholders approve the merger proposal, such disclosure will be deemed to be a recommendation change, as applicable, and ConocoPhillips will have the right to terminate the merger agreement.

Definition of Competing Proposal

A “competing proposal” means any contract, proposal, offer or indication of interest relating to any transaction or series of related transactions (other than transactions only with ConocoPhillips or any of its subsidiaries) involving, directly or indirectly:

96

•

any acquisition (by asset purchase, stock purchase, merger or otherwise) by any third party or group of any business or assets of Marathon Oil or any of its subsidiaries (including capital stock of or ownership interest in any subsidiary) that generated 20% or more of the value of Marathon Oil’s and its subsidiaries’ assets (by fair market value), net revenue or EBITDA for the preceding 12 months, or any license, lease or long-term supply agreement having a similar economic effect;

•

any acquisition of beneficial ownership by any third party or group of 20% or more of the outstanding shares of Marathon Oil common stock or any other securities entitled to vote on the election of directors or any tender or exchange offer that if completed would result in any person or group beneficially owning 20% or more of the outstanding shares of Marathon Oil common stock or any other securities entitled to vote on the election of directors; or

•

any merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving Marathon Oil or any of its subsidiaries.

Definition of Superior Proposal

A “superior proposal” means a bona fide written competing proposal (with references in the definition thereof to “20% or more” being deemed to be replaced with references to “all or substantially all”) that is not solicited after May 28, 2024 that, in the good faith determination of the Marathon Oil board, after consultation with its outside legal and financial advisors:

•

is more favorable to Marathon Oil’s stockholders from a financial point of view than the merger (after taking into account the time likely to be required to consummate such proposal and any adjustments or revisions to the terms of the merger agreement offered by ConocoPhillips in response to such proposal or otherwise);

•

is reasonably likely to be consummated on the terms proposed, taking into account any legal, financial, regulatory and stockholder approval requirements, the sources, availability and terms of any financing, financing market conditions and the existence of a financing contingency, the likelihood of termination, the timing of closing, the identity of the person or persons making the proposal and any other aspects considered relevant by the Marathon Oil board; and

•

if applicable, for which financing is fully committed or reasonably determined to be available by the Marathon Oil board.

Preparation of Proxy Statement/Prospectus and Registration Statement

Marathon Oil and ConocoPhillips have agreed to jointly prepare this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part, and to use commercially reasonable efforts to cause it to be filed with the SEC within 30 days following the date of the merger agreement. Prior to filing this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part (or any amendment or supplement thereto), or responding to any comments of the SEC with respect thereto, each of Marathon Oil and ConocoPhillips has agreed to (i) provide the other with a reasonable opportunity to review and comment on such document or response and (ii) give reasonable consideration to any comments made by the other party and its representatives (except with respect to documents filed by a party related to the transactions contemplated by the merger agreement which are incorporated by reference in this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part, the right to comment does not apply to information relating to the filing party’s business, financial condition or results of operations).

The parties have further agreed to (i) furnish all information concerning themselves and their affiliates that is required in connection with this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part, and any amendments or supplements thereto, (ii) use their commercially reasonable efforts to (A) cause this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part, to (B) comply as to form in all material respects with the requirements of the Securities Act and Exchange Act, respectively, and the rules and regulations promulgated thereunder and (C) not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under

97

which they were made, not misleading and (iii) have the registration statement, of which this proxy statement/​prospectus forms a part, declared effective under the Securities Act as promptly as practicable after its filing and keep the registration statement effective for so long as necessary to consummate the merger.

ConocoPhillips and Marathon Oil have agreed to make all necessary filings with respect to the merger and the transactions contemplated by the merger agreement under the Securities Act, the Exchange Act and applicable blue sky laws and the rules and regulations thereunder. Each party will advise the other party, promptly after it receives notice thereof, of the time when the registration statement, of which this proxy statement/prospectus forms a part, has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the ConocoPhillips common stock issuable in connection with the merger for offering or sale in any jurisdiction. Each of Marathon Oil and ConocoPhillips will use reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated.

If at any time prior to the effective time of the merger, any information relating to ConocoPhillips or Marathon Oil, or any of their respective affiliates, officers or directors, should be discovered by ConocoPhillips or Marathon Oil that should be set forth in an amendment or supplement to this proxy statement/​prospectus or the registration statement, of which this proxy statement/prospectus forms a part, so that such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information will promptly notify the other party and an appropriate amendment or supplement describing such information will be promptly filed with the SEC and, to the extent required by applicable law, disseminated to the Marathon Oil stockholders.

Special Meeting

Marathon Oil has agreed to take all action necessary in accordance with applicable laws and the organizational documents of Marathon Oil to duly give notice of, convene and hold (in person or virtually, in accordance with applicable law) a meeting of its stockholders for the purpose of obtaining the approval of the merger proposal by Marathon Oil stockholders, to be held as promptly as reasonably practicable after the clearance of this proxy statement/prospectus by the SEC and the registration statement, of which this proxy statement/prospectus forms a part, is declared effective by the SEC (and in any event use reasonable best efforts to convene such meeting within 40 days thereof). Except as expressly permitted by the merger agreement, the Marathon Oil board must recommend that Marathon Oil stockholders vote in favor of the merger proposal, solicit from Marathon Oil stockholders proxies in favor of the merger proposal and include such recommendation in this proxy statement/prospectus.

Marathon Oil may not, without the prior written consent of ConocoPhillips (such consent not to be unreasonably withheld, conditioned or delayed), adjourn, postpone or otherwise delay the special meeting; provided that Marathon Oil may, notwithstanding the foregoing, without the prior written consent of ConocoPhillips, and must if requested by ConocoPhillips, adjourn or postpone the special meeting (i) if, after consultation with ConocoPhillips, Marathon Oil believes in good faith that such adjournment or postponement is reasonably necessary to allow reasonable additional time to (A) solicit additional proxies in favor of the merger proposal or (B) distribute any supplement or amendment to this proxy statement/​prospectus, the distribution of which the Marathon Oil 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, and Marathon Oil must use its reasonable best efforts to obtain such a quorum as promptly as practicable. Notwithstanding the foregoing, (i) Marathon Oil may not, without the prior written consent of ConocoPhillips (such consent not to be unreasonably withheld, conditioned or delayed) postpone or adjourn the special meeting (A) more than a total of three times pursuant to the foregoing or (B) for a period exceeding 10 business days in the aggregate pursuant to the foregoing; and (ii) if the special meeting is postponed or adjourned, Marathon Oil must reconvene the special meeting at the earliest practicable date on which it reasonably expects to have sufficient affirmative votes for approval of the merger proposal; and provided, further that the special meeting may not be adjourned or postponed to a date on or after three business prior to the end date.

If requested by ConocoPhillips, Marathon Oil will promptly provide all voting tabulation reports relating to the special meeting and will otherwise keep ConocoPhillips reasonably informed regarding the

98

status of the solicitation and any material oral or written communications from or to Marathon Oil’s stockholders with respect thereto. Unless there has been a recommendation change, the parties have agreed to cooperate and use their reasonable best efforts to defend against any efforts by any of Marathon Oil’s stockholders or any other person to prevent the approval of the merger proposal by Marathon Oil stockholders.

Marathon Oil has agreed to, as soon as reasonably practicable following the date of the merger agreement, establish a record date prior to the effectiveness of the registration statement, of which this proxy statement/prospectus forms a part. Once Marathon Oil has established a record date for the special meeting, Marathon Oil may not change such record date or establish a different record date for the special meeting without the prior written consent of ConocoPhillips (which consent will not be unreasonably withheld, conditioned or delayed), unless required to do so by applicable law or its organizational documents.

Marathon Oil has further agreed that, without the prior written consent of ConocoPhillips or as required by applicable law, (i) the merger proposal will be the only matter (other than a non-binding advisory proposal regarding compensation that may be paid or become payable to the named executive officers of Marathon Oil in connection with the merger and matters of procedure) that Marathon Oil may propose to be acted on by the Marathon Oil stockholders at the special meeting and (ii) Marathon Oil may not call, hold or convene any meeting of the Marathon Oil stockholders other than the special meeting and the regular annual meetings of the Marathon Oil stockholders for 2025 and 2026 (provided that, (A) the proposals at such annual meetings are the same as those customarily presented by Marathon Oil as its annual meetings and (B) no proposals may be presented at such annual meetings that would violate the terms of the merger agreement or would reasonably be expected to materially delay, materially impede or prevent the consummation of the merger or the other transactions contemplated by the merger agreement).

Marathon Oil has agreed that its obligation to hold the special meeting will not be affected by (i) prior to the valid termination of the merger agreement in accordance with its terms, the making of a recommendation change or (ii) the commencement, announcement, disclosure or communication of any competing proposal or other proposal (including a superior proposal) or the occurrence or disclosure of any intervening event.

Access to Information

Subject to applicable law and certain other exceptions set forth in the merger agreement, Marathon Oil has agreed to (and to cause its subsidiaries to), upon request by ConocoPhillips, furnish ConocoPhillips with all information concerning itself, its subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any statement, filing, notice or application made by or on behalf of ConocoPhillips or its subsidiaries to any third party or any governmental entity in connection with the transactions contemplated by the merger agreement.

Marathon Oil has agreed to, and to cause each of its subsidiaries to, afford to ConocoPhillips and its representatives, during the period prior to the earlier of the effective time of the merger and the termination of the merger agreement, reasonable access, at reasonable times upon reasonable prior notice, to the officers, key employees, agents, properties, offices and other facilities of Marathon Oil and its subsidiaries and to their books, records, contracts and documents, and to cause each of its subsidiaries to, furnish reasonably promptly to ConocoPhillips and its representatives such information concerning its and its subsidiaries’ business, properties, contracts, records and personnel as may be reasonably requested, from time to time, by or on behalf of ConocoPhillips. ConocoPhillips and its representatives are required to conduct any such activities in such a manner as not to interfere unreasonably with the business or operations of Marathon Oil or its subsidiaries or otherwise cause any unreasonable interference with the prompt and timely discharge by the employees of Marathon Oil or its subsidiaries of their normal duties.

HSR and Other Regulatory Approvals

Except for the filings and notifications made pursuant to antitrust laws (as defined below), promptly after May 28, 2024, the parties have agreed to prepare and file with the appropriate governmental entities and other third parties all authorizations, consents, notifications, certifications, registrations, declarations and filings that are necessary in order to consummate the transactions contemplated by the merger agreement

99

and to diligently and expeditiously prosecute, and cooperate fully with each other in the prosecution of, such matters. However, in no event will either Marathon Oil or ConocoPhillips or any of their respective affiliates be required to pay any consideration to any third parties or give anything of value to obtain any such person’s authorization, approval, consent or waiver to effectuate the transactions contemplated by the merger agreement, other than filing, recordation or similar fees; provided that, Marathon Oil must take such actions if requested by ConocoPhillips so long as such actions are conditioned on the occurrence of the closing and ConocoPhillips has agreed to reimburse Marathon Oil for its reasonable out-of-pocket costs in connection with such actions in the event that the closing does not occur. ConocoPhillips and Marathon Oil will have the right to review in advance and each will consult with the other on and consider in good faith the views of the other in connection with, all of the information relating to ConocoPhillips or Marathon Oil, as applicable, and any of their respective subsidiaries, that appears in any filing made with, or written materials submitted to, any third party or any governmental entity in connection with the transactions contemplated by the merger agreement (including this proxy statement/prospectus and the registration statement, of which this proxy statement/prospectus forms a part). Marathon Oil and its subsidiaries will not agree to any actions, restrictions or conditions with respect to obtaining any consents, registrations, approvals, permits, expirations of waiting periods or authorizations in connection with the transactions contemplated by the merger agreement without the prior written consent of ConocoPhillips (which consent, subject to certain commitments relating to antitrust laws, may be withheld in ConocoPhillips’ sole discretion).

As promptly as reasonably practicable after May 28, 2024, but in no event later than 10 business days after May 28, 2024, each of the parties will make any filings required under the HSR Act. In addition, as promptly as reasonably practicable after May 28, 2024, but in no event later than 20 business days after May 28, 2024, ConocoPhillips will, at its own cost and with the cooperation and support of Marathon Oil and its subsidiaries, make any required merger notifications in connection with specified non-U.S. antitrust approvals. Each of ConocoPhillips and Marathon Oil will cooperate fully with each other and will furnish to the other such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of any filings under any applicable antitrust laws. Unless otherwise agreed, ConocoPhillips and Marathon Oil will each use its reasonable best efforts to ensure the prompt expiration or termination of any applicable waiting period under the HSR Act, ensure the prompt receipt of the specified non-U.S. antitrust approvals or the expiration or lapse of any legislated review periods (including any extensions thereof) in the jurisdictions where specified non-U.S. antitrust approvals are sought (as applicable) and bring about the closing as promptly as practicable. ConocoPhillips and Marathon Oil will each use its reasonable best efforts to respond to and comply with any request for information or documentary materials from any governmental entity charged with enforcing, applying, administering or investigating the HSR Act or any other law designed to prohibit, restrict or regulate actions with the purpose or effect of monopolization, restraint of trade, lessening of competition or foreign investment for the purpose of national security, public order or defense matters (which we refer to collectively as “antitrust laws”). Subject to certain exceptions, ConocoPhillips and Marathon Oil have agreed to (i) promptly notify each other of communications or proposed communications with governmental antitrust authorities, (ii) keep each other apprised of the status of any communications or developments with, and any inquiries or requests for additional information from, any governmental entity and (iii) not independently participate in discussions with any governmental entity without providing prior notice and an opportunity to participate to the other party (unless prohibited by such governmental entity).

ConocoPhillips has agreed to take any and all action necessary, including, but not limited to, (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets or businesses of Marathon Oil or ConocoPhillips or their respective subsidiaries; (ii) terminating, transferring or creating any existing relationships, contractual rights or obligations of Marathon Oil or ConocoPhillips or their respective subsidiaries; (iii) terminating any venture or other arrangement; (iv) creating any relationship, contractual rights or obligations of Marathon Oil or ConocoPhillips or their respective subsidiaries, or accepting any restriction on ConocoPhillips’ freedom of action following the closing; or (v) effectuating any other change or restructuring of Marathon Oil or ConocoPhillips or their respective subsidiaries (and, in each case, ConocoPhillips must enter into agreements or stipulate to the entry of an order or decree or file appropriate applications with any governmental antitrust authority in connection with any of the foregoing) (we refer to each of the foregoing as a “divestiture action”) to avoid the entry of or effect the dissolution of any law preliminarily or permanently restraining, enjoining or prohibiting the

100

consummation of the merger, or to ensure the expiration or termination of the waiting period under the HSR Act, and to receive the specified non-U.S. antitrust approvals, as promptly as reasonable practicable. However, none of ConocoPhillips or any of its subsidiaries is required to (i) take or agree to take (and, without the express prior written consent of ConocoPhillips, Marathon Oil and its subsidiaries will not take or agree to take) any divestiture action or other action that would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, financial condition or operations of ConocoPhillips and its subsidiaries from and after the effective time of the merger (but, for purposes of determining whether any effect is material, calculated as if ConocoPhillips and its subsidiaries from and after the effective time of the merger were collectively the same size as Marathon Oil and its subsidiaries prior to the date of the merger agreement), taken as a whole or (ii) agree to or otherwise accept a requirement for ConocoPhillips or any of its subsidiaries to provide prior notice to, or obtain prior approval from, any governmental entity except for any prior approval or prior notice requirement that is immaterial to ConocoPhillips (which we refer to as a “regulatory material adverse effect”).

Nothing in the merger agreement will require ConocoPhillips to take or agree to take any divestiture action or other action (other than non-material actions) with respect to ConocoPhillips and its subsidiaries (other than with respect to Marathon Oil and its subsidiaries (from and after the effective time of the merger)). Marathon Oil is required to agree to take any divestiture action requested by ConocoPhillips if such actions are only effective after the effective time of the merger and conditioned upon the closing of the merger. In the event that any divestiture action is proposed by or acceptable to a governmental entity, ConocoPhillips will have the right to determine the manner in which to implement the requirement of such governmental entity (but in no event will ConocoPhillips or Marathon Oil (or any of their respective subsidiaries or other affiliates) be required to take or effect any divestiture action that is not conditioned upon the closing of the merger).

In the event that any action is threatened or instituted challenging the merger as violative of any antitrust law, ConocoPhillips and Marathon Oil have agreed to cooperate with each other to avoid, contest or resist (as applicable) any such litigation, action or proceeding and to have vacated, lifted, reversed or overturned as promptly as practicable any law that is in effect that prohibits consummation of the merger so as to permit closing of the merger as promptly as practicable and in any event no later than the end date. ConocoPhillips and Marathon Oil will jointly determine the strategy to be pursued in seeking to remove impediments to closing and jointly direct any related proceedings; provided, however, in the event of disagreement between the parties, ConocoPhillips (after considering in good faith the views of Marathon Oil) will be entitled to make the final determination of the approach. Marathon Oil, ConocoPhillips and Merger Sub have each agreed not to engage in, or cause their respective subsidiaries to engage in, any acquisitions that could reasonably be expected to material impede, prevent or materially delay the expiration or termination of the required waiting period under the HSR Act or the receipt of other specified non-U.S. antitrust approvals.

Employee Matters

Marathon Oil and ConocoPhillips have agreed that the following will apply to the compensation and benefits to be provided, after the effective time of the merger, in respect of each individual who is employed as of the effective time of the merger by Marathon Oil or its subsidiaries (which we refer to as “continuing employees”):

•

consistent with the current practices of Marathon Oil and ConocoPhillips, Marathon Oil and ConocoPhillips will seek to attract and retain superior quality executive, managerial, technical and administrative personnel in every market in which they conduct activities and will generally implement compensation and benefit plans and policies necessary or appropriate to achieve this objective. It is the specific intention that, in each of the markets in which they operate, the compensation and benefit programs of Marathon Oil and ConocoPhillips will be competitive with those provided generally in their industry, both with respect to the type and variety of programs as well as the level of benefits afforded;

•

without limiting the generality of the foregoing bullet, except as otherwise expressly set forth in the merger agreement, and subject to applicable law and any obligations under any collective bargaining agreement, until the first anniversary of the closing date, ConocoPhillips will cause each continuing

101

employee who remains employed by ConocoPhillips or its subsidiaries (including Marathon Oil and its subsidiaries) to be provided with (i) base compensation (salary or wages, as applicable) and post-termination severance pay, in each case, not less than the level in effect for such continuing employee as of immediately prior to the effective time of the merger, (ii) target annual cash incentive compensation opportunities and target long-term incentive (equity-based) compensation opportunities each not less than that in effect for such continuing employee as of immediately prior to the effective time of the merger and (iii) employee benefits (including defined benefit retirement plan participation under the cash balance portion of Marathon Oil’s retirement plan and defined contribution retirement plan participation but excluding any other defined benefit pension and any change in control and other severance benefits) that are substantially comparable in the aggregate to those provided to such continuing employee immediately prior to the effective time of the merger; provided that, ConocoPhillips must maintain the following benefits without reduction or any other material changes except as required for compliance with tax qualification or other requirements under applicable law:

•

for the period beginning at the closing date and ending on the first anniversary of the closing date, defined benefit pension benefits under the cash balance portion of Marathon Oil’s retirement plan; and

•

for the period beginning at the closing date and ending on December 31, 2025, retiree health and life insurance benefits for those individuals who are participants in Marathon Oil’s or its subsidiaries’ retiree health and life insurance benefits as of immediately prior to the effective time of the merger and individuals who become eligible to participate in such retiree health and life insurance benefits during the period beginning at the closing date and ending on December 31, 2025.

•

for each continuing employee covered by a change in control severance plan of Marathon Oil or its subsidiaries immediately prior to the effective time of the merger, such coverage will continue in accordance with the terms of such plan immediately prior to the effective time of the merger until the first to occur of (i) the employee’s separation from service, (ii) the employee’s voluntary waiver of such benefit and (iii) the second anniversary of the closing date.

In addition, from and after the effective time of the merger, ConocoPhillips has agreed to, and to cause the surviving corporation and its subsidiaries to, as applicable:

•

credit the continuing employees for purposes of vesting and eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies and disability plans and policies, determining levels of benefits under the employee benefit plans sponsored, maintained or contributed to by ConocoPhillips or its affiliates (which we refer to as the “ConocoPhillips plans”) (other than to the extent it would result in a duplication of benefits) in which the continuing employee may be eligible to participate after the effective time of the merger, for such continuing employee’s service with Marathon Oil or its subsidiaries, to the same extent and for the same purposes that such service was taken into account under a corresponding Marathon Oil plan immediately prior to the effective time of the merger;

•

take commercially reasonable efforts to (i) cause each continuing employee to be immediately eligible to participate, without any waiting time, in any and all of the ConocoPhillips plans to the extent coverage under such ConocoPhillips plan replaces coverage under the comparable Marathon Oil plan in which such continuing employee participated immediately prior to the effective time of the merger, (ii) waive any limitation on health and welfare coverage of any continuing employee and his or her eligible dependents due to pre-existing conditions and/or waiting periods, active employment requirements and requirements to show evidence of good health under the applicable health and welfare ConocoPhillips plan to the extent such continuing employee and his or her eligible dependents are covered under a Marathon Oil plan immediately prior to the effective time of the merger, and such conditions, periods or requirements were satisfied or waived under such Marathon Oil plan and (iii) give each continuing employee credit for the plan year in which the closing date occurs towards applicable deductibles, coinsurance and annual out-of-pocket limits for expenses incurred prior to the closing date for which payment has been made under the applicable Marathon Oil plan for purposes of satisfying

102

all deductibles, coinsurance and annual out-of-pocket limits applicable to such continuing employee and his or her eligible dependents under the applicable ConocoPhillips plan for the applicable plan year as if such amounts had been paid in accordance with such ConocoPhillips plan; and

•

honor, in accordance with its terms (including terms related to the amendment or termination thereof), the Marathon Oil plans and each employment, severance, retention, change in control and termination arrangement between Marathon Oil or any of its subsidiaries, and any current or former officer, director or employee of Marathon Oil or such of its subsidiaries, to the extent such terms are in effect as of the date of the merger agreement.

Indemnification; Directors’ and Officers’ Insurance

Under the merger agreement, the surviving corporation is required to, and ConocoPhillips is required to cause the surviving corporation to, do the following:

•

for six years after the effective time of the merger, to the fullest extent permitted by applicable law, indemnify, defend and hold harmless (and advance expenses in connection therewith, subject to a customary undertaking from the applicable indemnified person to return such advances if it is determined by the final adjudication of a court of law that the indemnified person is not entitled to indemnification under the merger agreement) the present and former directors, officers, employees, fiduciaries and agents of the Marathon Oil and its subsidiaries, and any individuals serving in such capacity at or with respect to other persons at Marathon Oil’s and its subsidiaries’ request from and against any losses, claims, damages, liabilities, costs, expenses (including attorneys’ fees), judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect thereof) in respect of the indemnified persons having served in such capacity at or prior to the effective time of the merger, in each case, to the fullest extent permitted by the DGCL or provided under the organizational documents of Marathon Oil and its subsidiaries in effect as of the date of the merger agreement;

•

if any indemnified person is made party to any proceeding arising out of or relating to matters that would be indemnifiable pursuant to the foregoing bullet, advance fees, costs and expenses (including attorneys’ fees and disbursements) as incurred by such indemnified person in connection with and prior to the final disposition of such claim, action, suit, proceeding or investigation in each case to the extent Marathon Oil is required to do so and on the same terms as provided in the organizational documents of Marathon Oil and its subsidiaries in effect as of the date of the merger agreement; provided that, any indemnified person wishing to claim indemnification or advancement of expenses, upon learning of any such proceeding, must notify the surviving corporation (but the failure to notify shall not relieve the surviving corporation from the foregoing obligations that it may have, except to the extent such failure materially prejudices such party’s position with respect to such claims);

•

for six years after the effective time of the merger, maintain in effect provisions in the organizations documents of the surviving corporation and its subsidiaries (or in such documents of any successor to the business thereof) regarding elimination of liability of directors and officers, indemnification of officers, directors, employees, fiduciaries and agents and advancement of fees, costs and expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence as of the date of the merger agreement; and

•

for six years after the effective time of the merger, honor and comply with the obligations set forth in any indemnification agreements with indemnified persons set forth in Marathon Oil’s disclosure letter, and not amend, repeal or otherwise modify such agreement in a manner materially adverse to such indemnified person.

ConocoPhillips has agreed to guarantee and stand surety for, and cause the surviving corporation to honor its obligations under, the first three bullets of the foregoing paragraph.

Additionally, prior to the effective time of the merger, Marathon Oil may, or if its unable to do so, ConocoPhillips must cause the surviving corporation, as of the effective time of the merger to, obtain and

103

fully pay the premium for the non-cancellable extension of the directors’ and officers’ liability coverage of Marathon Oil’s existing directors’ and officers’ insurance policies and Marathon Oil’s existing fiduciary liability insurance policies, each with a reporting/discovery period of at least six years following the effective time of the merger, from an insurance carrier with the same or better credit rating as Marathon Oil’s current insurance carrier and having terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under Marathon Oil’s existing policies with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against an indemnified person by reason of him or her having served in such capacity that existed or occurred at or prior to the effective time of the merger. The cost of any such tail policy may not exceed 350% of the aggregate annual premium paid by Marathon Oil under its current policy and if the aggregate premiums of such tail policy exceeds such amount, Marathon Oil must, or ConocoPhillips must cause the surviving corporation to, as applicable, obtain a policy with the greatest coverage available, with respect to matters occurring prior to the effective time, for a cost not exceeding such amount.

In the event that ConocoPhillips or the surviving corporation or any of its successors or assignees (i) consolidates with or merges into any other person or (ii) transfers all or substantially all of its properties and assets to any person or consummates any division transaction, then, in each such case, to the extent necessary, ConocoPhillips has agreed to make proper provisions so that the successors and assigns of ConocoPhillips or the surviving corporation, as the case may be, will assume the indemnification, insurance coverage and expense advancement obligations set forth in the merger agreement.

Transaction Litigation

In the event of any litigation or other legal proceedings by any Marathon Oil or ConocoPhillips stockholder in relation to the merger agreement, the merger or other transactions contemplated by the merger agreement that is commenced or, to the knowledge of ConocoPhillips or Marathon Oil, is threatened, the relevant party will notify the other party of any such litigation and keep that party reasonably informed of its status. Marathon Oil has agreed to give ConocoPhillips a reasonable opportunity to participate in Marathon Oil’s defense or settlement of any transaction litigation against Marathon Oil, and will consult regularly with ConocoPhillips in good faith and give reasonable consideration to ConocoPhillips’ advice with respect to such litigation. Marathon Oil has agreed that it will not cease to defend, consent to the entry of any judgment, settle or offer to settle any litigation commenced against Marathon Oil without the prior written consent of ConocoPhillips, which may not be unreasonably withheld, conditioned or delayed.

Public Announcements

Any party to the merger agreement, its subsidiaries or their representatives may issue a public announcement or other public disclosures (i) required by applicable law, (ii) required by the rules of any stock exchange upon which such party’s or its subsidiary’s capital stock is traded or (iii) consistent with the final form of the joint press release announcing the merger and the investor presentation given to investors on the morning of May 29, 2024. However, in each case, such party must use its reasonable best efforts to afford the other party an opportunity to first review the content of the proposed disclosure and provide reasonable comments thereon. The merger agreement does not restrict a party’s ability to communicate with its employees, with the exception that prior to making any written (or prepared broad-based) communications to the directors, officers or employees of Marathon Oil or any of its subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by the merger agreement or compensation or benefits that are payable or to be provided following the effective time, Marathon Oil has agreed to provide ConocoPhillips with a copy of the intended communication (or written summary of any prepared broad-based oral communication) and a reasonable period of time to review and comment on the communication, and Marathon Oil will consider any timely comments in good faith.

Advice of Certain Matters; Notifications

Subject to compliance with applicable law, Marathon Oil and ConocoPhillips, as the case may be, have agreed to confer on a regular basis with each other and will promptly advise each other orally and in writing of any change or event having, or which would be reasonably likely to have, individually or in the aggregate, a Marathon Oil material adverse effect or a ConocoPhillips material adverse effect, as the case may be.

104

Except with respect to antitrust laws, Marathon Oil and ConocoPhillips have agreed to promptly provide each other (or their respective counsel) with copies of all filings made by such party or its subsidiaries with the SEC or any other governmental entity in connection with the merger agreement and the transactions contemplated by the merger agreement.

ConocoPhillips and Marathon Oil have agreed, subject to applicable law and as otherwise required by any governmental entity, to keep the other apprised of the status of matters relating to the completion of the merger, including promptly furnishing the other with copies of notices or other communications received by ConocoPhillips or Marathon Oil, as applicable, or any of its subsidiaries, from any third party or any governmental entity with respect to the transactions contemplated by the merger agreement (including those alleging that the approval or consent of such person is or may be required in connection with the transactions contemplated by the merger agreement). Additionally, each of ConocoPhillips and Marathon Oil must give prompt notice to the other party, upon becoming aware of (i) any condition, event or circumstance that will result in any of the closing conditions not being met or (ii) the failure by such party to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under the merger agreement.

Reasonable Best Efforts

ConocoPhillips and Marathon Oil have agreed to use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the merger and the other transactions contemplated by the merger agreement.

Section 16 Matters

Prior to the effective time of the merger, the parties have agreed to take all such steps as may be required to cause any dispositions of equity securities of Marathon Oil or acquisitions of equity securities of ConocoPhillips in connection with the merger agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Marathon Oil, or will become subject to such reporting requirements with respect to ConocoPhillips, to be exempt under Rule 16b-3 under the Exchange Act.

Stock Exchange Listing and Delistings

ConocoPhillips will take all action necessary to cause the shares of ConocoPhillips common stock to be issued in the merger to be approved for listing on the NYSE prior to the effective time of the merger.

Prior to the closing date, Marathon Oil will cooperate with ConocoPhillips and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable law and rules and policies of the NYSE to enable the delisting by the surviving corporation of the shares of Marathon Oil common stock from the NYSE and the deregistration of the shares of Marathon Oil common stock under the Exchange Act as promptly as practicable after the effective time of the merger, and in any event no more than 10 days after the effective time of the merger. If the surviving corporation is required to file any quarterly or annual report pursuant to the Exchange Act by a filing deadline that is imposed by the Exchange Act and which falls on a date within the 15 days following the closing date, Marathon Oil is required make available to ConocoPhillips, at least 10 business days prior to the closing date, a substantially final draft of any such annual or quarterly report required to be filed during such period.

Certain Indebtedness

If requested by ConocoPhillips in writing, Marathon Oil will, and will cause its subsidiaries to, on the terms set forth in the merger agreement, deliver all notices and take all other actions reasonably necessary to facilitate, on the closing date, (i) the termination of all commitments in respect of Marathon Oil’s existing revolving credit facility and (ii) the repayment in full of all obligations with respect to Marathon Oil’s existing revolving credit facility and Marathon Oil’s existing commercial paper program; provided that, to the extent Marathon Oil does not have unrestricted cash on hand in an amount sufficient to make such repayment

105

in full, Marathon Oil must have received funds from ConocoPhillips in an amount sufficient to make such repayment. In furtherance and not in limitation of the foregoing, the Marathon Oil and its subsidiaries must use commercially reasonable efforts to deliver to ConocoPhillips at least one business day prior to the closing date, executed payoff letters, in a form and substance reasonably satisfactory to ConocoPhillips, from the lenders, or the administrative agent on behalf of the lenders, under the Marathon Oil’s existing revolving credit facility and Marathon Oil’s existing commercial paper program.

Subject to certain restrictions and obligations, prior to completion of the merger, ConocoPhillips or any of its subsidiaries (or, in connection with any municipal bonds, any municipality on their behalf) may (i) commence (A) one or more offers to purchase for cash all of the outstanding debt issued under the indentures governing Marathon Oil’s senior notes and municipal bonds or (B) one or more offers to exchange any or all of the outstanding debt issued under the indentures governing Marathon Oil’s senior notes and municipal bonds for securities issued by (x) ConocoPhillips or its affiliates or (y) a municipality if such securities are supported by an agreement by ConocoPhillips or any of its affiliates to make payments sufficient to pay the principal of and interest on such securities and (ii) solicit the consent of the holders of debt issued under the indentures governing Marathon Oil’s senior notes and municipal bonds regarding proposed amendments to the applicable indenture, or otherwise see to obtain such proposed amendments, so long as the closing of any such transaction is conditioned on the occurrence of, and is not consummated until, the closing of the merger and any such transaction is funded solely using consideration provided by ConocoPhillips.

If requested in writing by ConocoPhillips, in lieu of or in addition to the foregoing offer or solicitation, as the case may be, Marathon Oil has agreed to use its reasonable best efforts, to the extent permitted under the indentures governing Marathon Oil’s senior notes and municipal bonds, to (i) issue one or more notices of optional redemption for all or a portion of the outstanding aggregate principal amount of the notes or bonds, pursuant to the redemption provisions of the respective indenture and (ii) take any other actions reasonably requested by ConocoPhillips to facilitate the satisfaction and discharge, defeasance or other similar action of the notes or bonds pursuant to the satisfaction and discharge, defeasance or other similar provisions of the respective indenture and the other provisions of each such indenture applicable thereto; provided that (A) any such redemption or satisfaction and discharge will be consummated using funds provided by ConocoPhillips and (B) consummation of any such redemption or satisfaction and discharge, defeasance or other similar action will not be a condition to closing of the merger.

Marathon Oil has agreed that it will, and will cause each of its subsidiaries to, use commercially reasonable best efforts to provide all customary cooperation as may be requested by ConocoPhillips in writing to assist ConocoPhillips in connection with any of the foregoing transactions. However, Marathon Oil’s obligation to cooperate is subject to certain exceptions and limitations, including, among others, that Marathon Oil is not required to (i) provide any cooperation to the extent that it would, in the good faith determination of Marathon Oil, unreasonably interfere with the business or operations of Marathon Oil or any of its subsidiaries, (ii) enter into any instrument or contract, agree to any change to any instrument or contract, or take any action with respect to its existing indebtedness prior to the closing of the merger that would be effective if the closing of the merger does not occur or (iii) deliver any notice of prepayment or redemption or similar notice that does not provide that such prepayment or redemption is conditioned upon the occurrence of the closing of the merger.

Subject to certain exceptions, ConocoPhillips has also agreed to indemnify, defend and hold harmless Marathon Oil, its subsidiaries and its and their respective representatives from and against any and all liabilities, losses, damages, claims, penalties, fines, taxes, costs, fees and expenses (including reasonable fees and expenses of one outside legal counsel, accountants, investment bankers, experts, consultants and other advisors, and the costs of all filing fees and printing costs) actually suffered or incurred by them in connection with such cooperation. In addition, ConocoPhillips has agreed to, promptly upon written request by Marathon Oil, reimburse Marathon Oil for all reasonable and documented out-of-pocket fees and expenses incurred by Marathon Oil, its subsidiaries or any of their respective representatives in connection with such cooperation. These obligations survive the closing of the merger and any termination of the merger agreement, regardless of whether or not the merger is consummated, and are intended to benefit, and may be enforced by, the representatives of Marathon Oil and its subsidiaries, who are each third-party beneficiaries of these obligations.

106

Tax Matters

Each of ConocoPhillips, Merger Sub and Marathon Oil will (and will cause its respective subsidiaries to) use its reasonable best efforts to cause the merger to qualify, and will not take or knowingly fail to take (and will cause its subsidiaries not to take or knowingly fail to take) any action that would or would reasonably be expected to prevent or impede the merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code. At the request of ConocoPhillips or Marathon Oil, each of ConocoPhillips, Merger Sub and Marathon Oil will use its reasonable best efforts and will cooperate with one another to obtain any opinion(s) of counsel to be issued in connection with (i) the consummation of the transactions contemplated by the merger agreement and/or (ii) the declaration of effectiveness of the registration statement by the SEC, in each case, regarding the U.S. federal income tax treatment of the transactions contemplated by the merger agreement, which cooperation shall include, for the avoidance of doubt, the delivery by ConocoPhillips, Merger Sub and Marathon Oil of duly executed certificates containing such representations, warranties and covenants as may be reasonably necessary or appropriate to enable such counsel to render any such opinion(s). Each of Marathon Oil and Parent will notify the other party promptly after becoming aware of any reason to believe that the merger may not qualify as a “reorganization” within the meaning of Section 368(a) of the Code. The parties have agreed that the merger agreement is intended to constitute, and is adopted as, a “plan of reorganization” for purposes of Sections 354 and 361 of the Code and within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the U.S. Treasury regulations promulgated under the Code.

Takeover Laws

Each party to the merger agreement has agreed that it will not take any action that would cause the transactions contemplated by the merger agreement to be subject to the requirements imposed by any “fair price,” “moratorium,” “control share acquisition,” “business combination” or any other anti-takeover statute or similar statute enacted under applicable law, and each of them will take all reasonable steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by the merger agreement from any such takeover law that purports to apply to the merger agreement or the transactions contemplated by the merger agreement.

Obligations of Merger Sub

ConocoPhillips has agreed to take all action necessary to cause Merger Sub and the surviving corporation to perform their respective obligations under the merger agreement.

Coordination of Quarterly Dividends

ConocoPhillips and Marathon Oil have agreed to each coordinate their record and payment dates for their regular quarterly dividends to ensure that the holders of Marathon Oil common stock will not receive two dividends, or fail to receive one dividend, in any quarter with respect to their Marathon Oil common stock and ConocoPhillips common stock that such holders receive in exchange in connection with the merger.

Resignations

Prior to the effective time, Marathon Oil has agreed to use its reasonable best efforts to cause each director of Marathon Oil to execute and deliver a resignation letter effectuating such director’s resignation as director of Marathon Oil, effective as of the effective time of the merger.

The merger agreement may also be terminated by either ConocoPhillips or Marathon Oil at any time prior to the effective time of the merger in any of the following situations:

•

if any governmental entity having jurisdiction over any party has issued any order, decree, ruling or injunction or taken any other action permanently restraining, enjoining or otherwise prohibiting the consummation of the merger and such order, decree, ruling or injunction or other action has become final and nonappealable, or if any law has been adopted that permanently makes the consummation of the merger illegal or otherwise permanently prohibited, so long as the terminating

109

party has not breached any material covenant or agreement under the merger agreement that has caused or resulted in such order, decree, ruling or injunction or other action;

•

if the merger has not been consummated on or before May 28, 2025 (which, as it may be extended as described in the proceeding provisos in this bullet, we refer to as the “end date”); provided that (i) if as of five business days before such date the conditions set forth in the second and third bullets under the section entitled “The Merger Agreement — Conditions to the Completion of the Merger — Mutual Conditions” above have not been satisfied, or a voluntary agreement with any governmental entity not to consummate the merger is in effect, but all of the other conditions to closing of the merger have been satisfied or waived (or are then capable of being satisfied if the closing of the merger were to take place on such date in the case of those conditions to be satisfied at the closing), then the end date will automatically be extended to November 28, 2025 and (ii) if as of five business days before November 28, 2025 the conditions set forth in the second and third bullets under the section entitled “The Merger Agreement — Conditions to the Completion of the Merger — Mutual Conditions” above have not been satisfied, or a voluntary agreement with any governmental entity not to consummate the merger is in effect, but all of the conditions to closing have been satisfied or waived (or are then capable of being satisfied if the closing of the merger were to take place on such date in the case of those conditions to be satisfied at the closing of the merger), then the end date will automatically be extended to May 28, 2026; provided, further, that the right to terminate the merger agreement for a lapse of the end date as described above will not be available to any party whose failure to fulfill any material covenant or agreement under the merger agreement was the cause of or resulted in the failure of the merger to occur on or before such date (which we refer to as the “end date termination event”);

•

in the event of a breach by the other party of any representation, warranty, covenant or other agreement contained in the merger agreement which would give rise to the failure of an applicable closing condition (and such breach is not curable prior to the end date, or if curable prior to the end date, has not been cured by the earlier of (i) 30 days after the giving of written notice to the breaching party of such breach and (ii) two business days prior to the end date); provided, however, that the terminating party is not itself then in breach (which, in the case of a breach by Marathon Oil, we refer to as a “Marathon Oil breach termination event” and, in the case of a breach by ConocoPhillips, we refer to as a “ConocoPhillips breach termination event”); or

•

if the Marathon Oil stockholders do not approve the merger proposal upon a vote held at a duly held special meeting, or at any adjournment or postponement of the special meeting (which we refer to as a “stockholder approval termination event”).

In addition, the merger agreement may be terminated by ConocoPhillips:

•

if prior to, but not after, the approval of the merger proposal by Marathon Oil stockholders, the Marathon Oil board or a committee of the Marathon Oil board has effected a recommendation change; or

•

if Marathon Oil, its subsidiaries or any of Marathon Oil’s directors or executive officers has materially breached Marathon Oil’s “no solicitation” obligations under the merger agreement as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation” beginning on page 92 (which we refer to as a “no solicitation breach termination event”).

Further, the merger agreement may be terminated by Marathon Oil:

•

if prior to, but not after, the approval of the merger proposal by Marathon Oil stockholders, to enter into a definitive agreement with respect to a superior proposal, provided that, Marathon Oil has (i) complied in all material respects with its “no solicitation” obligations under the merger agreement as described in the section entitled “The Merger Agreement — No Solicitation; Changes of Recommendation” beginning on page 92 and (ii) pays ConocoPhillips the termination fee as required under the merger agreement and described in the section entitled “The Merger Agreement — Termination — Termination Fees and Expenses” beginning on page 111 (which we refer to as a “superior proposal termination event”).

110

Termination Fees and Expenses

The merger agreement requires Marathon Oil to pay ConocoPhillips the termination fee of $557 million if:

•

ConocoPhillips terminates the merger agreement due to a recommendation change by Marathon Oil’s board or due to a no solicitation breach termination event;

•

Marathon Oil terminates the merger agreement due to a superior proposal termination event;

•

(i) (A) ConocoPhillips or Marathon Oil terminates the merger agreement due to a stockholder approval termination event and on or before the date of any such termination a competing proposal was publicly announced or publicly disclosed and not publicly withdrawn without qualification at least seven business days prior to the special meeting or (B) Marathon Oil or ConocoPhillips terminates the merger agreement due to an end date termination event or ConocoPhillips terminates the merger agreement due to a Marathon Oil breach termination event and following the date of the merger agreement and on or before the date of any such termination a competing proposal has been announced, disclosed or otherwise communicated to the Marathon Oil board and not withdrawn without qualification at least seven business days prior to the date of such termination (however, with respect to the preceding clauses (i)(A) and (i)(B), a competing proposal will not be deemed to have been “publicly withdrawn” by any person if, within 12 months of the termination of the merger agreement, Marathon Oil or any of its subsidiaries have entered into a definitive agreement with respect to, or have consummated, or have approved or recommended to the Marathon Oil stockholders or otherwise have not opposed, in the case of a tender offer or exchange offer, a competing proposal made by or on behalf of such person or any of its affiliates) and (ii) within 12 months after the date of such termination, Marathon Oil enters into a definitive agreement with respect to a competing proposal (or publicly approves or recommends to the Marathon Oil stockholders or otherwise does not oppose, in the case of a tender or exchange offer, a competing proposal) or consummates a competing proposal. For purposes of this paragraph, (x) in clause (ii), any reference in the definition of “competing proposal” to “20%” will be deemed to be a reference to “50%”, (y) a competing proposal will not be deemed to have been “publicly withdrawn” by any person if, within twelve months of the termination of the merger agreement, Marathon Oil or any of its subsidiaries will have entered into a definitive agreement with respect to, or will have consummated, or will have approved or recommended to the stockholders of Marathon Oil or otherwise not opposed, in the case of a tender offer or exchange offer, a competing proposal made by or on behalf of such person or any of its affiliates and (z) any competing proposal made prior to the date of the merger agreement will be deemed to have been made following the merger agreement if Marathon Oil breaches the “no solicitation” obligations described above.

The merger agreement also requires Marathon Oil to pay an expense reimbursement fee $86 million to ConocoPhillips representative of its transaction-related expenses if either Marathon Oil or ConocoPhillips terminates the merger agreement due to a stockholder approval termination event. In no event will ConocoPhillips be entitled to receive more than one termination fee or more than one expense reimbursement fee. If ConocoPhillips receives a termination fee, it will not be entitled to receive an expense reimbursement fee. Any expense reimbursement fee paid by Marathon Oil will be credited against any termination fee that is or may eventually become payable by Marathon Oil.

Effect of Termination

In the event of termination of the merger agreement pursuant to the provisions described in the section entitled “The Merger Agreement — Termination” ​(beginning on page 109), the merger agreement (other than certain provisions as set forth in the merger agreement) will become void and of no effect with no liability on the part of any party to the merger agreement. However, except as otherwise expressly provided in the merger agreement, no termination of the merger agreement will relieve any party to the merger agreement of any liability or damages to the other parties resulting from any willful and material breach of the merger agreement.

111

Expenses

Except as otherwise provided in the merger agreement, whether or not the merger is completed, all costs and expenses incurred in connection with the merger agreement, the merger and the other transactions contemplated by the merger agreement will be paid by the party incurring the expense.

Specific Performance; Remedies

ConocoPhillips, Marathon Oil and Merger Sub have agreed that each will be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of the merger agreement and to enforce specifically the terms and provisions of the merger agreement. ConocoPhillips, Marathon Oil and Merger Sub accordingly have agreed not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under the merger agreement.

The monetary remedies and the specific performance remedies set forth in the merger agreement will be the sole and exclusive remedies of ConocoPhillips and Merger Sub against Marathon Oil and its subsidiaries and any of their respective former, current or future directors, officers, stockholders, representatives or affiliates for any loss suffered as a result of the failure of the merger to be consummated, except in the case of fraud or a willful and material breach of any covenant, agreement or obligation (in which case only Marathon Oil will be liable for damages for such fraud or willful and material breach), and upon payment of such amount, none of Marathon Oil and its subsidiaries or any of their respective former, current or future directors, officers, stockholders, representatives or affiliates will have any further liability or obligation relating to or arising out of the merger agreement or the transactions contemplated by the merger agreement, except for the liability of Marathon Oil in the case of fraud or a willful and material breach of any covenant, agreement or obligation.

No Third Party Beneficiaries

Nothing in the merger agreement, express or implied, is intended to or confers upon any person other than ConocoPhillips, Marathon Oil and Merger Sub any right, benefit or remedy of any nature whatsoever under or by reason of the merger agreement, except:

•

from and after the effective time of the merger, the rights of the holders of shares of Marathon Oil common stock and certain Marathon Oil equity awards to receive the merger consideration; and

•

the right of the indemnified persons to enforce the obligations described under “The Merger Agreement — Indemnification; Directors’ and Officers’ Insurance” beginning on page 103.

Amendment

The merger agreement may be amended in writing at any time; however, after the approval by Marathon Oil stockholders of the merger proposal, no amendment or waiver may be made which requires further approval by Marathon Oil stockholders under applicable law or the rules and regulations of the NYSE without first obtaining such further approval. The merger agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

Governing Law

The merger agreement, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of relate to the merger agreement, or the negotiation, execution or performance of the merger agreement, are governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof.

112

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following discussion addresses the material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of shares of Marathon Oil common stock that exchange their shares of Marathon Oil common stock for shares of ConocoPhillips common stock in the merger. The discussion is based on the provisions of the Code, U.S. Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as currently in effect as of the date hereof and all of which are subject to change (possibly with retroactive effect) and all of which are subject to differing interpretations. Any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth in this proxy statement/prospectus. Tax considerations arising under foreign, state or local laws, or U.S. federal laws other than those pertaining to U.S. federal income tax, are not addressed in this proxy statement/prospectus.

For purposes of this discussion, the term “U.S. holder” refers to a beneficial owner of Marathon Oil common stock that is, for U.S. federal income tax purposes:

•

an individual citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any of its political subdivisions;

•

a trust if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons (as defined in the Code) have the authority to control all substantial decisions of the trust or (ii) such trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or

•

an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion applies only to U.S. holders of Marathon Oil common stock that hold their shares of Marathon Oil common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion is based upon the assumption that the merger will be completed in accordance with the terms of the merger agreement and as described in this proxy statement/prospectus. This discussion is not a complete description of all of the tax consequences of the merger and, in particular, does not address any consequences arising under the alternative minimum tax, unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010 or the Foreign Account Tax Compliance Act of 2010 (including the Treasury regulations promulgated thereunder and intergovernmental agreements entered into pursuant thereto or in connection therewith). This discussion also does not address all aspects of U.S. federal taxation that may be relevant to a particular U.S. holder in light of its personal circumstances or to U.S. holders subject to special treatment under the U.S. federal income tax laws, including, for example:

•

banks, thrifts, mutual funds or other financial institutions;

•

partnerships, S corporations or other pass-through entities (or investors in partnerships, S corporations or other pass-through entities);

•

insurance companies;

•

tax-exempt organizations or governmental organizations;

•

dealers or brokers in stocks, securities, commodities or currencies;

•

traders in securities that elect to use a mark-to-market method of accounting;

•

individual retirement or other deferred accounts;

•

persons that hold shares of Marathon Oil common stock as part of a straddle, hedge, appreciated financial position, constructive sale, conversion, integrated or other risk reduction transaction;

•

regulated investment companies;

•

real estate investment trusts;

•

U.S. holders whose “functional currency” is not the U.S. dollar;

•

persons who are not citizens or residents of the United States;

113

•

U.S. expatriates;

•

persons required to accelerate the recognition of any item of gross income as a result of such income being recognized on an “applicable financial statement”;

•

holders who directly, indirectly or constructively own (or at any time during the five-year period ending on the date of the disposition of such holder’s Marathon Oil common stock pursuant to the merger owned) 5% or more of Marathon Oil common stock; and

•

holders who acquired their shares of Marathon Oil common stock through the exercise of an employee stock option, as a restricted stock award, or otherwise as compensation or through a tax-qualified retirement plan.

If a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes holds shares of Marathon Oil common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partner and partnership. Partnerships and partners in such partnerships should consult their tax advisors about the tax consequences of the merger to them.

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 actual tax consequences of the merger to you may be complex and will depend on your specific situation and on factors that are not within ConocoPhillips’ or Marathon Oil’s control. You should consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances, including the applicability and effect of any state, local or foreign and other tax laws and of changes in those laws.

ConocoPhillips and Marathon Oil intend for the merger to be treated as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. The completion of the merger is not conditioned on the merger qualifying for the intended tax treatment or upon the receipt of an opinion of counsel to that effect, and neither ConocoPhillips nor Marathon Oil will request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. However, in connection with the effectiveness of the registration statement of which this proxy statement/prospectus is a part, each of Kirkland & Ellis LLP, counsel to Marathon Oil, and Wachtell, Lipton, Rosen & Katz, counsel to ConocoPhillips, delivered a legal opinion to the effect that:

(1)

the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code;

(2)

as a result, a U.S. holder that exchanges its shares of Marathon Oil common stock for shares of ConocoPhillips common stock generally will not recognize gain or loss for U.S. federal income tax purposes, except with respect to cash, if any, received in lieu of a fractional share of ConocoPhillips common stock;

(3)

each U.S. holder’s aggregate tax basis in the shares of ConocoPhillips common stock received in the merger (including any fractional share of ConocoPhillips common stock deemed received and disposed of for cash) generally will equal such U.S. holder’s aggregate adjusted tax basis in the shares of Marathon Oil common stock exchanged in the merger; and

the holding period of the shares of ConocoPhillips common stock received by a U.S. holder in the merger (including any fractional share of ConocoPhillips common stock deemed received and disposed of for cash) generally will include such U.S. holder’s holding period for the shares of Marathon Oil common stock exchanged in the merger.

These opinions are based upon currently applicable U.S. federal income tax law and rely on, among other things, various facts, assumptions, representations and warranties and covenants, including those contained in the merger agreement and in officer’s certificates provided by or on behalf of ConocoPhillips, Merger Sub and Marathon Oil. In the event of a change in applicable laws, or if any of these facts, assumptions, representations and warranties and covenants underlying the tax opinions described above is or becomes incorrect, incomplete, inaccurate or is violated, the validity of, and the conclusions reached in, such tax opinions may be affected or jeopardized. In addition, the opinions are subject to certain qualifications and limitations as set forth therein. Because the opinions are being delivered in connection with the

114

effectiveness of the registration statement, there can be no assurance that they will continue to remain valid at the effective time of the merger, and the closing of the transaction is not conditioned on the continuing validity of the opinions. Moreover, an opinion of counsel represents such counsel’s judgment and is not binding on the IRS or any court and the IRS or a court may disagree with the conclusions reached by an opinion of counsel. Notwithstanding the receipt by ConocoPhillips and Marathon Oil of the opinions of counsel, 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, that any of the other opinions fails to be true or that a court would not sustain such position.

If a U.S. holder holds different blocks of Marathon Oil common stock (generally, Marathon Oil common stock acquired on different dates or at different prices), such U.S. holder should consult its tax advisor with respect to the determination of the tax bases and/or holding periods of the particular shares of ConocoPhillips common stock received in the merger.

A U.S. holder of shares of Marathon Oil common stock who receives cash in lieu of a fractional share of ConocoPhillips common stock generally will be treated as having received the fractional share of ConocoPhillips common stock pursuant to the merger and then as having exchanged that fractional share for cash. As a result, a U.S. holder generally will recognize capital gain or loss with respect to cash received in lieu of a fractional share of ConocoPhillips common stock equal to the difference, if any, between the amount of cash received and the tax basis in such fractional share (determined as described above). Any gain or loss recognized generally will be long-term capital gain or loss if the shares of Marathon Oil common stock exchanged in the merger had been held for more than one year. The deductibility of capital losses is subject to limitations.

Payments of cash to U.S. holders in lieu of a fractional share of ConocoPhillips common stock in connection with the merger generally will be subject to information reporting and may be subject to U.S. federal backup withholding (currently, at a rate of 24%). To prevent backup withholding, U.S. holders of Marathon Oil common stock should provide the exchange agent with a properly completed IRS Form W-9 certifying such U.S. holder’s correct taxpayer identification number and certain other information, or otherwise establish an applicable exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld from payments to a U.S. holder of shares of Marathon Oil common stock under the backup withholding rules may be refunded or credited against such U.S. holder’s U.S. federal income tax liability, provided that such U.S. holder timely furnishes the required information to the IRS.

The preceding discussion is intended only as an overview 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 you. Thus, you are strongly encouraged to consult your tax advisor as to the specific tax consequences resulting to you from the merger, including tax return reporting requirements, the applicability and effect of federal, state, local and other tax laws and the effect of any proposed changes in the tax laws.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial information (the “pro forma financial statements”) combines the historical consolidated financial position and results of operations of ConocoPhillips and the historical consolidated financial position and results of operations of Marathon Oil after giving effect to the merger as further described in Note 1 — Description of the Transactions and Basis of Presentation and the pro forma effects of certain assumptions and adjustments described in “Notes to the Unaudited Pro Forma Combined Financial Statements” below. The pro forma financial statements have been prepared to give effect to the following (collectively, the “Transactions”):

•

Application of the acquisition method of accounting under the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”) where the assets acquired and liabilities assumed of Marathon Oil will be recorded by ConocoPhillips at their respective fair values as of the closing date;

•

Preliminary adjustments to conform the financial statement presentation of Marathon Oil to those of ConocoPhillips; and

•

Adjustments to reflect estimated transaction costs of the merger.

The following pro forma financial statements and related notes are based on and should be read in conjunction with:

•

The historical audited consolidated financial statements of ConocoPhillips and the related notes included in ConocoPhillips’ Annual Report on Form 10-K as of and for the year ended December 31, 2023;

•

The historical audited consolidated financial statements of Marathon Oil and the related notes included in Marathon Oil’s Annual Report on Form 10-K as of and for the year ended December 31, 2023;

•

The historical unaudited interim consolidated financial statements of ConocoPhillips and the related notes included in ConocoPhillips’ Quarterly Report on Form 10-Q as of and for the three months ended March 31, 2024; and

•

The historical unaudited interim consolidated financial statements of Marathon Oil and the related notes included in Marathon Oil’s Quarterly Report on Form 10-Q as of and for the three months ended March 31, 2024.

The unaudited pro forma combined balance sheet as of March 31, 2024, gives pro forma effect to the Transactions as if they had occurred on March 31, 2024. The unaudited pro forma combined income statements for the three months ended March 31, 2024, and for the year ended December 31, 2023, give pro forma effect to the Transactions as if they had occurred on January 1, 2023.

The pro forma financial statements are provided for informational purposes only. The pro forma financial statements are not necessarily, and should not be assumed to be, an indication of the actual results that would have been achieved had the Transactions been completed as of the dates indicated or that may be achieved in the future. The pro forma financial statements have been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using the assumptions set forth in the notes to the pro forma financial statements. While the pro forma financial statements do not include the realization of any cost savings from operating efficiencies, synergies or other restructuring activities which might result from the merger, management’s estimates of certain cost savings to be realized following closing of the merger are illustrated in Note 6 to the pro forma financial statements. Further, there may be additional charges related to any potential restructuring or other integration activities resulting from the merger, the timing, nature and amount of which management cannot identify as of the date of this proxy statement/prospectus, and thus, such charges are not reflected in the pro forma financial statements.

The pro forma financial statements have been prepared using the acquisition method of accounting pursuant to the provisions of ASC 805, whereby ConocoPhillips is considered the accounting acquirer. The merger consideration will be allocated to the identifiable assets acquired and liabilities assumed based

116

upon their estimated fair values as of the close date of the merger, and any excess value of the merger consideration over the acquired net assets will be recognized as goodwill, if applicable. The assets acquired and liabilities assumed of Marathon Oil have been measured based on various preliminary estimates using assumptions that ConocoPhillips believes are reasonable, based on information that is currently available. As a result of the foregoing, the pro forma adjustments are preliminary and are subject to change as additional information becomes available and as additional analysis is performed. Accordingly, actual adjustments may differ from the amounts reflected in the pro forma financial statements and the differences may be material.

NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Note 1. Description of the Transactions and Basis of Presentation

Acquisition of Marathon Oil

On May 28, 2024, ConocoPhillips entered into the Merger Agreement with Marathon Oil and Merger Sub, pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Marathon Oil, with Marathon Oil continuing as the surviving corporation in the merger and a wholly-owned subsidiary of ConocoPhillips. As a result of the merger, each issued and outstanding share of Marathon Oil’s common stock, par value $1.00 per share, will be converted into the right to receive the exchange ratio of 0.255 shares of ConocoPhillips common stock.

Basis of Presentation

The accompanying pro forma financial statements have been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using the assumptions set forth in these notes to the pro forma financial statements.

The unaudited pro forma combined balance sheet as of March 31, 2024, combines the historical consolidated balance sheets of ConocoPhillips and Marathon Oil, giving effect to the Transactions as if they had occurred on March 31, 2024. The unaudited pro forma combined income statements for the three months ended March 31, 2024, and for the year ended December 31, 2023, combines the historical consolidated income statements of ConocoPhillips and Marathon Oil, giving effect to the Transactions as if they had occurred on January 1, 2023.

The pro forma financial statements and explanatory notes have been prepared to illustrate the effects of the merger of ConocoPhillips and Marathon Oil under the acquisition method of accounting whereby ConocoPhillips is considered the accounting acquirer. The pro forma financial statements are presented for informational purposes only and do not necessarily indicate the financial results of the combined company had the companies been combined at the beginning of the periods presented, nor do they necessarily indicate the results of operations in future periods or the future financial position of the combined company. The results of operations of the combined company will be reported prospectively after closing following completion of the merger. Under the acquisition method of accounting, the assets and liabilities of Marathon Oil, as of closing, will be recorded by ConocoPhillips at their estimated fair values and any excess of the merger consideration over the fair value of Marathon Oil’s net assets will be allocated to goodwill, if applicable. The pro forma allocation of the merger consideration reflected in the pro forma financial statements is subject to adjustment and may vary materially from the actual allocation that will be recorded at the time the merger is completed since, among other reasons, certain information will not be available until after the merger is completed.

The pro forma financial statements do not include the realization of any cost savings from operating efficiencies, synergies or other restructuring activities which might result from the merger. Management’s estimates of certain cost savings to be realized following closing of the merger are illustrated in Note 6 to the pro forma financial statements.

Note 2. Significant Accounting Policies and Reclassification Adjustments

During the preparation of the pro forma financial statements, ConocoPhillips performed a preliminary analysis of Marathon Oil’s historical financial information to identify differences in accounting policies and financial statement presentation as compared to those of ConocoPhillips. Accordingly, certain reclassification adjustments have been made to conform Marathon Oil’s historical financial statements to presentation used by ConocoPhillips in the preparation of the pro forma financial statements.

The following reclassification adjustments were made to conform the presentation of Marathon Oil’s historical consolidated balance sheet as of March 31, 2024, to ConocoPhillips’ presentation:

(a)

Represents a reclassification of “Receivables, net” to “Accounts and notes receivable, net” and “Accounts and notes receivable — related parties”.

122

(b)

Represents a reclassification of “Other current assets” to “Prepaid expenses and other current assets”.

(c)

Represents a reclassification of “Equity method investments” to “Investments and long-term receivables”.

(d)

Represents a reclassification of finance lease balances and related right-of-use assets from “Other assets” to “Net properties, plants and equipment”, from “Other current liabilities” to “Short-term debt” and from “Other liabilities and deferred credits” to “Long-term debt”.

(e)

Represents a reclassification of “Accounts payable” to “Accounts payable — related parties”.

(f)

Represents a reclassification of “Commercial paper” to “Short-term debt”.

(g)

Represents a reclassification of “Accrued taxes” to “Accrued income and other taxes”.

(h)

Represents a reclassification of “Payroll and benefits payable” to “Other accruals”.

(i)

Represents a reclassification of “Other current liabilities” to “Other accruals”.

(j)

Represents a reclassification of “Asset retirement obligations” to “Asset retirement obligations and accrued environmental costs”.

(k)

Represents a reclassification of “Defined benefit postretirement plan obligations” to “Employee benefit obligations”.

(l)

Represents a reclassification of “Additional paid-in capital” to “Capital in excess of par”.

(m)

Represents a reclassification of “Held in treasury, at cost” to “Treasury stock”.

The following reclassification adjustments were made to conform the presentation of Marathon Oil’s historical consolidated income statements for the three months ended March 31, 2024, and for the year ended December 31, 2023, to ConocoPhillips’ presentation:

(n)

Represents a reclassification of revenue amounts from “Revenues from contracts with customers” to “Sales and other operating revenues”.

(o)

Represents a reclassification of results from commodity derivatives from “Net gain (loss) on commodity derivatives” to “Sales and other operating revenues”.

(p)

Represents a reclassification of other expenses and other income from “Other income (expense)” to “Other income” and “Other expenses”.

(q)

Represents a reclassification of production expenses from “Production” to “Production and operating expenses”.

(r)

Represents a reclassification of shipping, handling and other operating expenses from “Shipping, handling and other operating, including related party” to “Production and operating expenses”.

(s)

Represents a reclassification of general and administrative expenses from “General and administrative” to “Selling, general and administrative expenses”.

(t)

Represents a reclassification of interest, other expenses and other income from “Net interest and other” to “Interest and debt expense”, “Other expenses” and “Other income”.

(u)

Represents a reclassification of pension activity from “Other net periodic benefit credits” to “Other expenses”.

123

Note 3. Preliminary Purchase Price Allocation

Estimated Merger Consideration

The total preliminary merger consideration is calculated as follows:

(Amounts in millions)	As of March 31, 2024
Preliminary estimated fair value of ConocoPhillips common stock to be issued(1)	​	$	16,250
Obligation to cash settle shares underlying certain Marathon Oil stock-based awards	​	​	27
Other merger consideration attributable to Marathon Oil stock-based awards	​	​	26
Total preliminary merger consideration	​	$	16,303

(1)

Represents the estimated fair value of 143,005 thousand shares of ConocoPhillips common stock to be issued to Marathon Oil stockholders pursuant to the Merger Agreement. This estimate is based on the number of eligible shares of Marathon Oil common stock as of May 31, 2024 at a 0.255 Exchange Ratio and ConocoPhillips’ closing stock price of $113.63 as of June 11, 2024.

The final merger consideration could significantly differ from the amounts presented in the pro forma financial statements due to fluctuations in ConocoPhillips’ common stock price up to the closing date.

A sensitivity analysis related to the fluctuation in ConocoPhillips’ common stock price was performed to assess the impact of a hypothetical change of 10% on ConocoPhillips’ share closing price on the estimated purchase consideration. ConocoPhillips believes that a 10% fluctuation in the market price of its common stock is reasonably possible based on historical volatility. An increase in the closing price of ConocoPhillips common stock could potentially result in goodwill as of the closing date.

The following table shows the estimated purchase consideration resulting from a change in ConocoPhillips’ share price (amounts in millions except share price):

Change in Share Price	Share Price			Estimated Purchase Consideration
Increase of 10%	​	$	124.99	​	$	17,933
Decrease of 10%	​	$	102.27	​	$	14,673

Preliminary Purchase Price Allocation

The estimated merger consideration as shown in the table above is allocated to the identifiable assets to be acquired and liabilities to be assumed of Marathon Oil based on their preliminary estimated fair values. The fair value assessments are preliminary and are based on available information and certain assumptions, which ConocoPhillips believes are reasonable. The following table sets forth a preliminary allocation of the estimated merger consideration to the fair value of the identifiable tangible and intangible assets to be

124

acquired and liabilities to be assumed of Marathon Oil using Marathon Oil’s balance sheet as of March 31, 2024, adjusted for reclassifications and presentational alignment to that of ConocoPhillips’ historical financial information:

(Amounts in millions)	As of March 31, 2024
Assets	​	​	​
Cash and cash equivalents	​	$	49
Accounts and notes receivable, net	​	​	1,253
Accounts and notes receivable – related parties	​	​	23
Inventories	​	​	179
Prepaid expenses and other current assets	​	​	53
Investments and long-term receivables	​	​	472
Net properties, plants and equipment	​	​	24,076
Other assets	​	​	318
Total assets to be acquired	​	$	26,423
Liabilities	​	​	​
Accounts payable	​	$	1,495
Accounts payable – related parties	​	​	19

Other liabilities and deferred credits	​	​	201
Total liabilities to be assumed	​	$	10,120
Net assets to be acquired	​	$	16,303

Note 4. Adjustments to the Unaudited Pro Forma Combined Balance Sheet

Transaction accounting adjustments include the following adjustments related to the unaudited pro forma combined balance sheet as of March 31, 2024, as follows:

(a)

Represents an adjustment of $6,755 million to the carrying value of Marathon Oil’s acquired properties, plants and equipment from their recorded net book values to their preliminary estimated fair values.

(b)

Represents an adjustment of $3 million to “Short-term debt” and $8 million to “Long-term debt” to reflect the preliminary estimated fair value.

(c)

Represents an adjustment to “Other accruals” to record estimated transaction costs of $82 million and merger consideration related accrual to cash settle shares underlying certain Marathon Oil stock-based awards of $27 million.

(d)

Reflects a $1,607 million increase to “Deferred income taxes” based on the blended federal and state statutory rates of approximately 23.5% for the United States and a blended rate of approximately 25.9% for Equatorial Guinea, multiplied by the fair value adjustments related to the assets acquired and liabilities assumed.

Note 5. Adjustments to the Unaudited Pro Forma Combined Income Statements

Transaction accounting adjustments include the following adjustments related to the unaudited pro forma combined income statements for the three months ended March 31, 2024, and for the year ended December 31, 2023, as follows:

(a)

Represents an adjustment to reflect a decrease in “Depreciation, depletion and amortization” expense of $95 million and $337 million for the three months ended March 31, 2024, and the year ended December 31, 2023, respectively. This adjustment was calculated in accordance with the successful efforts method of accounting for oil and gas properties, which were based on the preliminary purchase price allocation of the estimated fair value of the net properties, plants and equipment.

(b)

Represents an adjustment to record $82 million of estimated transaction costs related to the merger for the year ended December 31, 2023. These costs are non-recurring and are not expected to have a continuing impact on the combined company’s operating results in future periods.

(c)

Represents an adjustment to increase “Interest and debt expense”, to amortize Marathon Oil’s debt fair value adjustment by $1 million and $4 million for the three months ended March 31, 2024, and the year ended December 31, 2023, respectively.

(d)

Reflects tax effect of the adjustments above at the blended federal and state statutory rates of approximately 23.5% for the United States and a blended rate of approximately 25.9% for Equatorial Guinea, and a $2 million expense adjustment for the impact of the merger on foreign tax credit for the three months ended March 31, 2024.

(e)

Reflects tax effect of the adjustments above at the blended federal and state statutory rates of approximately 23.5% for the United States and blended rate of approximately 25.9% for Equatorial Guinea, and a $15 million expense adjustment for the impact of the merger on foreign tax credit for the year ended December 31, 2023.

Note 6. Management Adjustments to the Unaudited Pro Forma Combined Income Statements

Management expects that, following completion of the merger with Marathon Oil, the post-acquisition company will realize certain cost savings as compared to the historical combined costs of ConocoPhillips and Marathon Oil operating independently. Such cost savings, which result from the elimination of duplicate costs and the manner in which the post-acquisition company will be integrated and managed prospectively, are expected soon after completion of the merger, to be realized within the first year and continuing into future periods. Management’s adjustments are based on estimated cost savings as a result of the integration of personnel and related reduction in payroll and other costs of the combined company and are not reflected in the pro forma income statements.

Material limitations of these adjustments include not fully realizing the anticipated benefits, taking longer to realize these cost savings, or other adverse effects that ConocoPhillips does not currently foresee. Further, there may be additional charges incurred in achieving these cost savings, such as severance and benefit costs, for which management cannot determine the nature and amount as of the date of this proxy statement/prospectus, and thus, such charges are not reflected in the pro forma income statements. These adjustments reflect all Management’s Adjustments that are, in the opinion of management, necessary to fairly state the pro forma financial information presented. Future results may vary significantly from the pro forma financial information presented because of various factors, including those discussed in the section entitled “Risk Factors” beginning on page 26.

Had the merger been completed as of January 1, 2023, management estimates that the following production and operating expenses and selling, general and administrative expenses would not have been incurred, on a pre-tax basis:

•

For the three months ended March 31, 2024, $38 million related to lower production and operating expenses and $62 million related to reduced selling, general and administrative expenses.

•

For the year ended December 31, 2023, $150 million related to lower production and operating expenses and $250 million related to reduced selling, general and administrative expenses.

127

The tax effect on the above adjustments has been calculated based on the blended federal and state statutory rates of approximately 23.5% for the United States and a blended rate of approximately 25.9% for Equatorial Guinea.

These annual cost savings primarily relate to optimizing overlapping costs and consolidating field operations, and do not include annual capital savings of $100 million related to improved capital efficiencies.

The following tables present the estimated effects on the pro forma combined income statements from elimination of the identified expenses:

the Lower 48 geographic area as of December 31, 2023. ConocoPhillips anticipates 97 million barrels of proved developed reserves acquired as part of the merger to be reflected in the Africa geographic area in our supplemental oil and gas disclosures, with a pro forma combined total of 329 million barrels of reserves for the Africa geographic area as of December 31, 2023.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserve Quantities

The following tables present the estimated pro forma discounted future net cash flows at December 31, 2023. The pro forma standardized measure information set forth below gives effect to the merger as if the merger had been completed on January 1, 2023. The disclosures below were determined by referencing the “Standardized Measure of Discounted Future Net Cash Flows” reported in ConocoPhillips’ and Marathon Oil’s respective Annual Reports on Form 10-K for the year ended December 31, 2023; an explanation of the underlying methodology applied, as required by SEC regulations, can be found within the respective Annual Report on Form 10-K. See “Where You Can Find More Information” beginning on page 157. The calculations assume the continuation of existing economic, operating and contractual conditions at December 31, 2023.

Therefore, the following estimated pro forma standardized measure is not necessarily indicative of the results that might have occurred had the merger been completed on January 1, 2023, and is not intended to be a projection of future results. Future results may vary significantly from the results reflected because of various factors, including those discussed in the section entitled “Risk Factors” beginning on page 26.

DESCRIPTION OF CONOCOPHILLIPS COMMON STOCK

The following describes the material terms of the common stock of ConocoPhillips. This description is qualified in its entirety by reference to the ConocoPhillips certificate of incorporation, dated May 14, 2008 (which is filed as Exhibit 3.1 to the registration statement, of which this proxy statement/prospectus forms a part), and the ConocoPhillips bylaws, as amended and restated on May 16, 2023 (which is filed as Exhibit 3.2 to the registration statement, of which this proxy statement/prospectus forms a part). For more information, see the section entitled “Where You Can Find More Information” beginning on page 157.

Authorized Capital Stock

ConocoPhillips is authorized to issue 2.5 billion shares of common stock, par value $0.01 per share, and 500 million shares of preferred stock, par value $0.01 per share.

Common Stock

Each holder of ConocoPhillips common stock is entitled to one vote per share in the election of directors and on all other matters submitted to the vote of stockholders. However, except as otherwise required by law, holders of ConocoPhillips common stock are not entitled to vote on any amendment to its certificate of incorporation that relates solely to the terms of any series of preferred stock if holders of preferred stock are entitled to vote on the amendment under the certificate of incorporation or Delaware law. There are no cumulative voting rights, meaning that the holders of a majority of the shares of ConocoPhillips common stock voting for the election of directors can elect all of the directors standing for election. Subject to the rights of the holders of any series of preferred stock that may be outstanding from time to time, each share of ConocoPhillips common stock will have an equal and ratable right to receive dividends as may be declared by the board of directors out of funds legally available for the payment of dividends, and, in the event of liquidation, dissolution or winding up, will be entitled to share equally and ratably in the assets available for distribution to stockholders. No holder of ConocoPhillips common stock will have any preemptive or other subscription rights to purchase or subscribe for any of ConocoPhillips’ securities. In addition, holders of ConocoPhillips common stock have no conversion rights, and there are no redemption or sinking fund provisions applicable to ConocoPhillips common stock. ConocoPhillips common stock is traded on the NYSE under the trading symbol “COP.” The transfer agent for ConocoPhillips common stock is Computershare Shareowner Services LLC.

Anti-Takeover Provisions of ConocoPhillips’ Certificate of Incorporation and Bylaws

The ConocoPhillips certificate of incorporation and bylaws contain provisions that could delay or make more difficult the acquisition of control of us through a hostile tender offer, open market purchases, proxy contest, merger or other takeover attempt that a stockholder might consider in his or her best interest, including those attempts that might result in a premium over the market price of ConocoPhillips common stock.

Authorized but Unissued Stock

ConocoPhillips has 2.5 billion authorized shares of common stock and 500 million authorized shares of preferred stock. One of the consequences of its authorized but unissued common stock and undesignated preferred stock may be to enable its board of directors to make more difficult or to discourage an attempt to obtain control of us. If, in the exercise of its fiduciary obligations, the board of directors determined that a takeover proposal was not in ConocoPhillips’ best interest, the board of directors could authorize the issuance of those shares without stockholder approval, subject to limits imposed by the NYSE. The shares could be issued in one or more transactions that might prevent or make the completion of a proposed change of control transaction more difficult or costly by:

•

diluting the voting or other rights of the proposed acquirer or insurgent stockholder group;

•

creating a substantial voting bloc in institutional or other hands that might undertake to support the position of the incumbent board; or

•

effecting an acquisition that might complicate or preclude the takeover.

134

In this regard, the ConocoPhillips certificate of incorporation grants its board of directors broad power to establish the rights and preferences of the authorized and unissued preferred stock. The board of directors could establish one or more series of preferred stock that entitle holders to:

•

vote separately as a class on any proposed merger or consolidation;

•

cast a proportionately larger vote together with ConocoPhillips’ common stock on any transaction or for all purposes;

•

elect directors having terms of office or voting rights greater than those of other directors;

•

convert preferred stock into a greater number of shares of common stock or other securities;

•

demand redemption at a specified price under prescribed circumstances related to a change of control of us; or

•

exercise other rights designed to impede a takeover.

Stockholder Action by Written Consent; Special Meetings of Stockholders

The ConocoPhillips certificate of incorporation provides that no action that is required or permitted to be taken by stockholders at any annual or special meeting may be taken by written consent of stockholders in lieu of a meeting, and that special meetings of stockholders may be called only by the board of directors or the chairman of the board.

Advance Notice Procedure for Director Nominations and Stockholder Proposals; Proxy Access

The ConocoPhillips bylaws provide the manner in which stockholders may give notice of stockholder nominations and other business to be brought before an annual meeting. In general, to bring a matter before an annual meeting or to nominate a candidate for director, a stockholder must give notice of the proposed matter or nomination not less than 90 and not more than 120 days prior to the first anniversary date of the immediately preceding meeting. If the annual meeting is not within 30 days before or after the anniversary date of the preceding annual meeting, the stockholder notice must be received not earlier than the 120th day prior to the date of such annual meeting and not later than the close of business on the later of (i) 90 days prior to the date of the annual meeting or (ii) if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of the annual meeting, the close of business on the 10th day following the day on which notice of the annual meeting was mailed or first publicly disclosed.

In addition to the director nomination provisions described above, the ConocoPhillips bylaws contain a “proxy access” provision that provides that any stockholder or group of up to twenty stockholders who have owned 3% or more of ConocoPhillips’ outstanding common stock continuously for at least three years to nominate and include in ConocoPhillips’ proxy materials director candidates constituting up to 20% of its board of directors or two directors, whichever is greater, provided that the stockholders and the nominees satisfy the eligibility requirements specified in the ConocoPhillips bylaws. A stockholder proposing to nominate a person for election to the ConocoPhillips board through the proxy access provision must provide ConocoPhillips with a notice requesting the inclusion of the director nominee in its proxy materials and other required information not less than 120 days nor more than 150 days prior to the first anniversary of the date on which ConocoPhillips first mails its proxy materials for the preceding year’s annual meeting of stockholders. In addition, an eligible stockholder may include a written statement of not more than 500 words supporting the candidacy of such stockholder nominee. The complete proxy access provision for director nominations is set forth in the ConocoPhillips bylaws. These procedures may limit the ability of stockholders to nominate candidates for director and bring other business before a stockholders meeting, including the consideration of any transaction that could result in a change of control and that might result in a premium to the ConocoPhillips stockholders.

Fair Price Provision

The ConocoPhillips certificate of incorporation requires that specified business combinations involving a person or entity that beneficially owns 15% or more of the outstanding shares of its voting stock or that is an affiliate of that person, which ConocoPhillips refers to as a related person, must be approved by (i) at

135

least 80% of the votes entitled to be cast by the voting stock and (ii) at least 66-2/3% of the votes entitled to be cast by the voting stock other than voting stock owned by the related person. These supermajority requirements do not apply if:

•

a majority of the directors who are unaffiliated with the related person and who were in office before the related person became a related person approve the transaction; or

•

specified fair price conditions are met that in general provide that the payment received by the stockholders in the business combination is not less than the amount the related person paid or agreed to pay for any shares of ConocoPhillips voting stock acquired within one year of the business combination.

Amendment of Certificate of Incorporation and Bylaws

Amendments to the ConocoPhillips certificate of incorporation generally must be approved by its board of directors and by a majority of the outstanding stock entitled to vote on the amendment, and, if applicable, by majority of the outstanding stock of each class or series entitled to vote on the amendment as a class or series. Under the corporation’s certificate of incorporation, the affirmative vote of shares representing not less than 80% of the votes entitled to be cast by the voting stock is required to alter, amend or adopt any provision inconsistent with or repeal the provisions that, among others, (i) control the constitution of the board of directors, (ii) deny stockholders the right to call a special meeting or to act by written consent, (iii) limit or eliminate the liability of the directors and (iv) set the 80% supermajority threshold applicable with respect to the provisions above. Additionally, the affirmative vote of shares representing (i) not less than 80% of the votes entitled to be cast by the voting stock, voting together as a single class, and (ii) not less than 66-2/3% of the votes entitled to be cast by the voting stock not owned, directly or indirectly, by any related person is required to amend, repeal or adopt any provisions inconsistent with, the fair price provision described above. The ConocoPhillips bylaws have similar supermajority vote requirements for provisions relating to, among others, special stockholder meetings; prohibition on action by stockholder written consent; nominating directors and bringing business before an annual stockholder meeting; the number, classification and qualification of directors; filling vacancies on the board of directors; and removing directors.

Limitation of Liability of Directors

To the fullest extent permitted by Delaware law, ConocoPhillips’ directors will not be personally liable to ConocoPhillips or ConocoPhillips’ stockholders for monetary damages for breach of fiduciary duty as a director. Delaware law currently permits the elimination of all liability for breach of fiduciary duty, except liability: for any breach of the duty of loyalty to the corporation or stockholders; for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law; for unlawful payment of a dividend or unlawful stock purchases or redemptions; and for any transaction from which the director derived an improper personal benefit.

As a result, neither ConocoPhillips nor its stockholders have the right, through stockholders’ derivative suits on ConocoPhillips’ behalf, to recover monetary damages against a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior, except in the situations described above.

Delaware Anti-Takeover Law

ConocoPhillips is a Delaware corporation and is subject to Section 203 of the DGCL, which regulates corporate acquisitions. Section 203 prevents an “interested stockholder,” which is defined generally as a person owning 15% or more of a corporation’s voting stock, or any affiliate or associate of that person, from engaging in a broad range of “business combinations” with the corporation for three years after becoming an interested stockholder unless:

•

the board of directors of the corporation had previously approved either the business combination or the transaction that resulted in the stockholder’s becoming an interested stockholder;

•

upon completion of the transaction that resulted in the stockholder’s becoming an interested stockholder, that person owned at least 85% of the voting stock of the corporation outstanding at

136

the time the transaction commenced, excluding shares owned by persons who are directors and also officers and shares owned in employee stock plans in which participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•

following the transaction in which that person became an interested stockholder, the business combination is approved by the board of directors of the corporation and holders of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation’s directors, if such extraordinary transaction is approved or not opposed by a majority of the directors who were directors prior to any person becoming an interested stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors. Section 203 may make it more difficult for a person who would be an interested stockholder to effect various business combinations with a corporation for a three-year period.

COMPARISON OF STOCKHOLDERS’ RIGHTS

This section describes the material differences between the rights of holders of shares of Marathon Oil common stock and the rights of holders of shares of ConocoPhillips common stock. Marathon Oil and ConocoPhillips are each incorporated under the laws of the State of Delaware and, accordingly, the rights of Marathon Oil stockholders and ConocoPhillips stockholders are both governed by the laws of the State of Delaware. The differences between the rights of Marathon Oil stockholders and ConocoPhillips stockholders primarily result from differences between the organizational documents of Marathon Oil and ConocoPhillips. As a result of the merger, holders of shares of Marathon Oil common stock that receive merger consideration in respect of their shares of Marathon Oil common stock will become holders of shares of ConocoPhillips common stock. As a result, following the merger, the rights of Marathon Oil stockholders who become ConocoPhillips stockholders in the merger will continue to be governed by the laws of the State of Delaware and will also then be governed by the ConocoPhillips certificate of incorporation and the ConocoPhillips bylaws.

This section does not include a complete description of all differences between the rights of Marathon Oil stockholders and ConocoPhillips stockholders, nor does it include a complete description of the specific rights referred to below. Furthermore, the description of some of the differences in these rights in this section is not intended to indicate that other differences that may be equally important do not exist. All Marathon Oil stockholders and ConocoPhillips stockholders are urged to read carefully the relevant provisions of the DGCL, as well as each company’s organizational documents. This summary is qualified in its entirety by reference to the full text of each of the ConocoPhillips certificate of incorporation, the ConocoPhillips bylaws, the ConocoPhillips corporate governance guidelines, the Marathon Oil certificate of incorporation, the Marathon Oil bylaws and the Marathon Oil corporate governance guidelines. For information on how to obtain a copy of these documents, see the section entitled “Where You Can Find More Information” beginning on page 157.

ConocoPhillips Stockholders	Marathon Oil Stockholders
The ConocoPhillips bylaws provide that expenses incurred by such an indemnified person in defending any civil, criminal, administrative or investigative action, suit or proceeding will be paid by ConocoPhillips in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such indemnified person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by ConocoPhillips.	The Marathon Oil bylaws provide that Marathon Oil will pay all expenses reasonably incurred by or on behalf of the indemnitee in connection with that proceeding within 10 days after Marathon Oil receives a statement or statements from the indemnitee requesting the advance or advances from time to time, whether prior to or after final disposition of that proceeding; provided, however, that Marathon Oil will have no obligation to advance expenses if such advance will be in violation of applicable law.
State Anti-Takeover Provisions

Such consolidated financial statements and ConocoPhillips management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2023 are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

DeGolyer and MacNaughton, an independent petroleum engineering consulting firm, performed a process review of the processes and controls used within ConocoPhillips in its preparation of proved reserves estimates as of December 31, 2023. This process review report appeared as an exhibit to ConocoPhillips’ Annual Report on Form 10-K for the year ended December 31, 2023, and is incorporated by reference herein in reliance on the authority of such firm as experts in such matters.

Marathon Oil Corporation

The financial statements of Marathon Oil and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Report on Internal Control over Financial Reporting) incorporated in this proxy statement/prospectus by reference to Marathon Oil’s Annual Report on Form 10-K for the year ended December 31, 2023 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

154

HOUSEHOLDING OF PROXY MATERIALS

To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding Marathon Oil common stock but who share the same address, Marathon Oil has adopted a procedure approved by the SEC called “householding.” Under this procedure, certain stockholders of record who have the same address and last name will receive only one copy of this proxy statement/​prospectus until such time as one or more of these stockholders notifies Marathon Oil that they want to receive separate copies. In addition, the broker, bank or other nominee for any stockholder who is a beneficial owner of Marathon Oil common stock may deliver only one copy of this proxy statement/prospectus to multiple stockholders who share the same address, unless that broker, bank or other nominee has received contrary instructions from one or more of the Marathon Oil stockholders. This procedure reduces duplicate mailings and saves printing costs and postage fees, as well as natural resources. Marathon Oil stockholders affected by householding will continue to have access to and utilize separate proxy voting instructions. To opt out of householding for future proxy materials, please write to Marathon Oil’s Shareholder Services Office at 990 Town and Country Boulevard, Houston, Texas 77024.

155

FUTURE STOCKHOLDER PROPOSALS

If the 2025 annual meeting occurs, pursuant to the Marathon Oil bylaws, Marathon Oil stockholders of record may present proposals that are proper subjects for consideration at an annual meeting and/or nominate persons to serve on the Marathon Oil board at such annual meeting.

Eligible stockholders may nominate a candidate for election to Marathon Oil’s board or submit a proposal for inclusion in Marathon Oil’s proxy statement for the 2025 annual meeting (which we refer to as the “2025 annual meeting proxy statement”) in accordance with the “proxy access” provisions of the Marathon Oil bylaws. Stockholder proposals and nominations for director submitted for inclusion in the 2025 annual meeting proxy statement must be received in writing by Marathon Oil’s Secretary at 990 Town and Country Boulevard Houston, TX 77024 on or after December 11, 2024, and no later than the close of business on January 10, 2025, and must otherwise comply with all of the requirements of the Marathon Oil bylaws.

EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE COMPANY AND MERGER SUB; EXCHANGE

3.1   Effect of the Merger on Capital Stock.   At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company, or any holder of any securities of Parent, Merger Sub or the Company:

(a)   Capital Stock of Merger Sub.   Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and shall represent one (1) fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation, which shall constitute the only outstanding share of common stock of the Surviving Corporation immediately following the Effective Time.

(b)   Capital Stock of the Company.

(i)   Subject to the other provisions of this Article III, each share of common stock, par value $1.00 per share, of the Company (“Company Common Stock”), issued and outstanding immediately prior to the Effective Time (excluding any Excluded Shares and any Converted Shares) (such shares of Company Common Stock, the “Eligible Shares”), shall be converted into the right to receive from Parent that number of fully paid and nonassessable shares of Parent Common Stock equal to the Exchange Ratio (the “Merger Consideration”), subject to Section 3.3(h). As used in this Agreement, “Exchange Ratio” means 0.2550.

(ii)   All such shares of Company Common Stock, when so converted, shall cease to be outstanding and shall automatically be canceled and cease to exist. Each holder of a share of Company Common Stock that was outstanding immediately prior to the Effective Time (other than Excluded Shares and Converted Shares) shall cease to have any rights with respect thereto, except the right to receive (A) the Merger Consideration, (B) any dividends or other distributions in accordance with Section 3.3(g) and (C) any cash to be paid in lieu of any fractional shares of Parent Common Stock in accordance with Section 3.3(h), in each case to be issued or paid in consideration therefor upon the exchange of any Certificates or Book-Entry Shares, as applicable, in accordance with Section 3.3(a).

(iii)   All shares of Company Common Stock held by the Company as treasury shares or by Parent or Merger Sub immediately prior to the Effective Time and, in each case, not held on behalf of third parties (collectively, “Excluded Shares”) shall automatically be canceled and cease to exist as of the Effective Time, and no consideration shall be delivered in exchange therefor. Each share of Company Common Stock that is owned by any direct or indirect Subsidiary of the Company or Parent (other than Merger Sub) (“Converted Shares”) shall automatically be converted into a number of fully paid and nonassessable shares of Parent Common Stock equal to the Exchange Ratio (subject to adjustment in accordance with Section 3.1(c)).

(c)   Impact of Stock Splits, Etc.   In the event of any change in (i) the number of shares of Company Common Stock, or securities convertible or exchangeable into or exercisable for shares of Company Common Stock, or (ii) the number of shares of Parent Common Stock, or securities convertible or exchangeable into or exercisable for shares of Parent Common Stock (including options to purchase Parent Common Stock), in each case issued and outstanding after the date of this Agreement and prior to the Effective Time by reason of any stock split, reverse stock split, stock dividend, subdivision, reclassification, recapitalization, combination, exchange of shares or the like, the Exchange Ratio shall be equitably adjusted to reflect the effect of such change and, as so adjusted, shall from and after the date of such event, be the Merger Consideration, subject to further adjustment in accordance with this Section 3.1(c). Nothing in this Section 3.1(c) shall be construed to permit the Parties to take any action except to the extent consistent with, and not otherwise prohibited by, the terms of this Agreement.

A-9

3.2   Treatment of Equity Compensation Awards.

(a)   Company RSU Awards.

(i)   Except as set forth in Section 3.2(a)(ii), at the Effective Time, each outstanding award of restricted stock units in respect of Company Common Stock that vests solely based on service (a “Company RSU Award”) granted pursuant to the Company’s 2019 Incentive Compensation Plan, as amended from time to time, or any predecessor plan (the “Company Stock Plan”), shall be canceled and converted into an award of restricted stock units in respect of Parent Common Stock (a “Parent RSU Award”) covering that number of shares of Parent Common Stock (rounded to the nearest whole share) equal to the product of (i) the total number of shares of Company Common Stock subject to such Company RSU Award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio. Each Parent RSU Award corresponding to a Company RSU Award outstanding as of the date hereof shall, except as otherwise provided in this Section 3.2(a), be subject to substantially the same terms and conditions as applied to the corresponding Company RSU Award immediately prior to the Effective Time.

(ii)   At the Effective Time, each Company RSU Award and each outstanding award of deferred stock units in respect of Company Common Stock (a “Company DSU Award”), in each case, granted to a non-employee director of the Company pursuant to the Company Stock Plan that is outstanding immediately prior to the Effective Time shall, by virtue of the occurrence of the Closing and without any action by Parent, Merger Sub, the Company or the holder thereof, immediately vest with respect to 100% of the shares of Company Common Stock subject to such Company RSU Award or Company DSU Award, which shares of Company Common Stock shall be converted into the right to receive (A) the Merger Consideration in accordance with Section 3.1(b) with respect to each share of Company Common Stock and (B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to such Company RSU Award or Company DSU Award, payable by the Surviving Corporation as promptly as administratively possible after the Closing, but in no event later than ten (10) Business Days following the Closing.

(b)   Company Option Awards.   At the Effective Time, each outstanding and vested compensatory option to purchase shares of Company Common Stock (a “Company Option Award”) granted pursuant to the Company Stock Plan shall be canceled and converted into the right to receive that number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to the quotient of (i) the product of (A) the excess, if any, of the Merger Consideration Value over the per share exercise price of the applicable Company Option Award, multiplied by (B) the number of shares of Company Common Stock subject to such Company Option Award immediately prior to the Effective Time, divided by (ii) the Parent Closing Price. Any Company Option Award that has an exercise price per share of Company Common Stock that is equal to or greater than the Merger Consideration Value shall be canceled for no consideration. The term “Merger Consideration Value” means the product of (x) the Exchange Ratio multiplied by (y) the Parent Closing Price.

(c)   Company Performance Unit Awards.   At the Effective Time, each outstanding award of performance units denominated in shares of Company Common Stock (a “Company Performance Unit Award”) granted pursuant to the Company Stock Plan shall, by virtue of the occurrence of the Closing and without any action by Parent, Merger Sub, the Company or the holder thereof, immediately vest and be converted into the right to receive (i) in the case of Company Performance Unit Awards that vest based on total shareholder return, (A) that number of shares of Parent Common Stock (rounded to the nearest whole share) equal to the product of (x) the number of shares of Company Common Stock subject to such Company Performance Unit Award immediately prior to the Effective Time reflecting the attainment of the applicable performance metrics at the maximum level of performance (which, for the avoidance of doubt, shall be equal to 200% of the target number of performance units subject to such Company Performance Unit Award) multiplied by (y) the Exchange Ratio and (B) an amount in cash equal to the accrued but unpaid dividend equivalents with respect to each such share of Company Common Stock, or (ii) in the case of Company Performance Unit Awards that vest based on free cash flow, an amount in cash reflecting the attainment of the applicable performance metrics at the maximum level of performance (which, for the avoidance of doubt, shall be equal to 200% of the target number of performance units subject to such Company Performance Unit

A-10

Award) multiplied by the average of the daily closing price of a share of Company Common Stock during the final thirty (30) calendar days ending on the last trading day immediately preceding the Closing Date (the “Average Price “); provided, however that if any values were banked under such award based on a price per share of Company Common Stock that is greater than the Average Price then such higher price shall be used for such portion of the award, plus any dividend equivalents accrued with respect to such Company Performance Unit Award, in the case of each of the foregoing clauses (i) and (ii), as promptly as administratively possible after the Closing, but in no event later than ten (10) Business Days after the Closing.

(d)   Section 409A.   To the extent that any award described in this Section 3.2 constitutes nonqualified deferred compensation subject to Section 409A of the Code, any payment contemplated hereby with respect to such award shall be made in accordance with this Agreement and the applicable award’s terms or, if later, at the earliest time permitted under the terms of such award that will not result in the application of a tax or penalty under Section 409A of the Code.

(e)   Administration.   Prior to the Effective Time, the Company Board and/or the compensation committee of the Company Board shall take such action and adopt such resolutions as are required or appropriate to (i) effectuate the treatment of the Company RSU Awards, Company DSU Awards, Company Performance Unit Awards and Company Option Awards (collectively, the “Company Equity Awards”) pursuant to the terms of this Section 3.2, (ii) if requested by Parent in writing, cause the Company Stock Plan to terminate effective as of the Effective Time and (iii) take all actions reasonably required to effectuate any provision of this Section 3.2, including to ensure that from and after the Effective Time, neither Parent nor the Surviving Corporation will be required to deliver shares of Company Common Stock or other capital stock of the Company to any Person pursuant to or in settlement of any equity awards of the Company, including any Company Equity Awards. Parent shall take such actions as are necessary for the conversion of Company RSU Awards pursuant to this Section 3.2, including reservation, issuance and listing of shares of Parent Common Stock as are necessary to effectuate the transactions contemplated by this Section 3.2. Parent shall prepare and file with the SEC a registration statement on an appropriate form, or a post-effective amendment to a registration statement previously filed under the Securities Act, with respect to the shares of Parent Common Stock subject to the Parent RSU Awards and, where applicable, shall use its reasonable best efforts to have such registration statement declared effective as of the Effective Time and to maintain the effectiveness of such registration statement covering the Parent RSU Awards (and to maintain the current status of the prospectus contained therein) for so long as the Parent RSU Awards remain outstanding.

3.3   Payment for Securities; Exchange.

(a)   Exchange Agent; Exchange Fund.   Prior to the Effective Time, Parent shall enter into an agreement with Parent’s or the Company’s transfer agent to act as agent for the holders of Company Common Stock in connection with the Merger (the “Exchange Agent”) and to receive the Merger Consideration and cash sufficient to pay cash in lieu of fractional shares pursuant to Section 3.3(h) to which such holders shall become entitled pursuant to this Article III. At or prior to the Effective Time, Parent shall deposit, or cause to be deposited, with the Exchange Agent, for the benefit of the holders of Eligible Shares, for issuance in accordance with this Article III through the Exchange Agent, the number of shares of Parent Common Stock issuable in respect of Eligible Shares pursuant to Section 3.1. Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 3.3(g) and to make payments in lieu of fractional shares pursuant to Section 3.3(h). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued in exchange for Eligible Shares pursuant to this Agreement out of the Exchange Fund. Except as contemplated by this Section 3.3(a), Section 3.3(g) and Section 3.3(h), the Exchange Fund shall not be used for any other purpose. Any cash and shares of Parent Common Stock deposited with the Exchange Agent (including as payment for fractional shares in accordance with Section 3.3(h) and any dividends or other distributions in accordance with Section 3.3(g)) shall hereinafter be referred to as the “Exchange Fund.” Parent or the Surviving Corporation shall pay all charges and expenses, including those of the Exchange Agent, in connection with the exchange of Eligible Shares pursuant to this Agreement. The

A-11

cash portion of the Exchange Fund may be invested by the Exchange Agent as reasonably directed by Parent. To the extent, for any reason, the amount in the Exchange Fund is below that required to make prompt payment of the aggregate cash payments contemplated by this Article III, Parent shall promptly replace, restore or supplement the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to make the payment of the aggregate cash payments contemplated by this Article III. Any interest or other income resulting from investment of the cash portion of the Exchange Fund shall become part of the Exchange Fund, and any amounts in excess of the amounts payable hereunder shall, at the discretion of Parent, be promptly returned to Parent or the Surviving Corporation.

(b)   Payment Procedures.

(i)   Certificates.   As soon as practicable after the Effective Time, Parent shall cause the Exchange Agent to deliver to each record holder, as of immediately prior to the Effective Time, of an outstanding certificate or certificates that immediately prior to the Effective Time represented Eligible Shares (“Certificates”), a notice advising such holders of the effectiveness of the Merger and a letter of transmittal (“Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which shall be in a customary form and agreed to by Parent and the Company prior to the Closing) and instructions for use in effecting the surrender of Certificates for payment of the Merger Consideration set forth in Section 3.1(b)(i). Upon surrender to the Exchange Agent of a Certificate, together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other customary documents as may be reasonably required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor (A) one or more shares of Parent Common Stock (which shall be in uncertificated book-entry form) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 3.1 (after taking into account all shares of Company Common Stock then held by such holder) and (B) a check in the amount equal to the cash payable in lieu of any fractional shares of Parent Common Stock pursuant to Section 3.3(h) and dividends and other distributions pursuant to Section 3.3(g).

(ii)   Non-DTC Book-Entry Shares.   As soon as practicable after the Effective Time, Parent shall cause the Exchange Agent to deliver to each record holder, as of immediately prior to the Effective Time, of Eligible Shares represented by book-entry (“Book-Entry Shares”) not held through DTC, (A) a notice advising such holders of the effectiveness of the Merger, (B) a statement reflecting the number of shares of Parent Common Stock (which shall be in uncertificated book-entry form) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 3.1 (after taking into account all shares of Company Common Stock then held by such holder) and (C) a check in the amount equal to the cash payable in lieu of any fractional shares of Parent Common Stock pursuant to Section 3.3(h) and dividends and other distributions pursuant to Section 3.3(g).

(iii)   DTC Book-Entry Shares.   With respect to Book-Entry Shares held through DTC, Parent and the Company shall cooperate to establish procedures with the Exchange Agent and DTC to ensure that the Exchange Agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the Closing Date, upon surrender of Eligible Shares held of record by DTC or its nominees in accordance with DTC’s customary surrender procedures, the Merger Consideration, cash in lieu of fractional shares of Parent Common Stock, if any, and any unpaid non-stock dividends and any other dividends or other distributions, in each case, that DTC has the right to receive pursuant to this Article III.

(iv)   No interest shall be paid or accrued on any amount payable for Eligible Shares pursuant to this Article III.

(v)   With respect to Certificates, if payment of the Merger Consideration (including any dividends or other distributions with respect to Parent Common Stock pursuant to Section 3.3(g) and any cash in lieu of fractional shares of Parent Common Stock pursuant to Section 3.3(h)) is to

A-12

be made to a Person other than the record holder of such Eligible Shares, it shall be a condition of payment that shares so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such shares surrendered or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not applicable. With respect to Book-Entry Shares, payment of the Merger Consideration (including any dividends or other distributions with respect to Parent Common Stock pursuant to Section 3.3(g) and any cash in lieu of fractional shares of Parent Common Stock pursuant to Section 3.3(h)) shall only be made to the Person in whose name such Book-Entry Shares are registered in the stock transfer books of the Company as of the Effective Time. Until surrendered as contemplated by this Section 3.3(b)(v), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of such shares of Company Common Stock, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 3.3(h) and any dividends or other distributions to which such holder is entitled pursuant to Section 3.3(g).

(c)   Termination of Rights.   All Merger Consideration (including any dividends or other distributions with respect to Parent Common Stock pursuant to Section 3.3(g) and any cash in lieu of fractional shares of Parent Common Stock pursuant to Section 3.3(h)) paid upon the surrender of and in exchange for Eligible Shares in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Common Stock. At the Effective Time, the stock transfer books of the Surviving Corporation shall be closed immediately, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged for the Merger Consideration payable in respect of the Eligible Shares previously represented by such Certificates, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 3.3(h) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 3.3(g), without any interest thereon.

(d)   Termination of Exchange Fund.   Any portion of the Exchange Fund that remains undistributed to the former stockholders of the Company on the one hundred eightieth (180th) day after the Closing Date shall be delivered to Parent, upon demand, and any former common stockholders of the Company who have not theretofore received the Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock to which they are entitled pursuant to Section 3.3(h) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 3.3(g), in each case without interest thereon, to which they are entitled under this Article III shall thereafter look only to the Surviving Corporation and Parent for payment of their claim for such amounts.

(e)   No Liability.   None of the Surviving Corporation, Parent, Merger Sub or the Exchange Agent shall be liable to any holder of Company Common Stock for any amount of Merger Consideration properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to the time that is immediately prior to the time at which Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity, any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f)   Lost, Stolen, or Destroyed Certificates.   If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by the Surviving Corporation, the posting by such Person of 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, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in

A-13

respect of the shares of Company Common Stock formerly represented by such Certificate, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 3.3(h) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 3.3(g).

(g)   Distributions with Respect to Unexchanged Shares of Parent Common Stock.   No dividends or other distributions declared or made with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the whole shares of Parent Common Stock that such holder would be entitled to receive upon surrender of such Certificate and no cash payment in lieu of fractional shares of Parent Common Stock shall be paid to any such holder, in each case until such holder shall surrender such Certificate in accordance with this Section 3.3. Following surrender of any such Certificate, there shall be paid to such holder of whole shares of Parent Common Stock issuable in exchange therefor, without interest, (i) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all whole shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if such whole shares of Parent Common Stock were issued and outstanding as of the Effective Time.

(h)   No Fractional Shares of Parent Common Stock.   No certificates or scrip or shares representing fractional shares of Parent Common Stock shall be issued upon the exchange of Eligible Shares and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a stockholder of Parent or a holder of shares of Parent Common Stock. Notwithstanding any other provision of this Agreement, each holder of Eligible Shares exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Certificates and Book-Entry Shares held by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to the product of (i) such fractional part of a share of Parent Common Stock multiplied by (ii) the volume-weighted average price of Parent Common Stock for the five (5) consecutive trading days ending two (2) trading days prior to the Closing Date as reported by Bloomberg, L.P. (the “Parent Closing Price”). As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall so notify Parent, and Parent shall cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof. The payment of cash in lieu of fractional shares of Parent Common Stock is not a separately bargained-for consideration but merely represents a mechanical rounding-off of the fractions in the exchange.

(i)   Withholding Taxes.   Notwithstanding anything in this Agreement to the contrary, Parent, Merger Sub, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement any amount required to be deducted and withheld with respect to the making of such payment under applicable Law and shall pay the amount deducted or withheld to the appropriate Taxing Authority in accordance with applicable Law; provided that, except as otherwise required by Law, the Parties agree that the Merger Consideration payable or deliverable pursuant to this Agreement shall not be subject to withholding under Section 1445 of the Code or the Treasury Regulations promulgated thereunder. Parent, Merger Sub, the Surviving Corporation and the Exchange Agent, as the case may be, shall cooperate in good faith to minimize any such deduction or withholding. To the extent such amounts are deducted or withheld and paid over to the appropriate Taxing Authority by Parent, Merger Sub, the Surviving Corporation or the Exchange Agent, as the case may be, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

3.4   No Appraisal Rights.   In accordance with the DGCL, no appraisal rights shall be available with respect to the Transactions.

(ii)   prior to, but not after, the receipt of the Company Stockholder Approval, the Company and its Representatives may engage in the activities prohibited by Sections 6.4(b)(ii) or 6.4(b)(iii) with any Person if (A) the Company receives a bona fide written Company Competing Proposal from such Person that was not solicited at any time following the execution of this Agreement and (B) such Company Competing Proposal did not arise from a material breach of the obligations set forth in this Section 6.4; provided, however, that (1) no information that is prohibited from being furnished pursuant to Section 6.4(b) may be furnished until the Company receives an executed confidentiality agreement from such Person containing limitations on the use and disclosure of non-public information furnished to such Person by or on behalf of the Company that are no less favorable in all material respects than the terms of the Confidentiality Agreement, as determined by the Company Board in good faith after consultation with its legal counsel (provided, further, that such confidentiality agreement does not contain provisions which prohibit the Company from providing any information to Parent in accordance with this Section 6.4 or that otherwise prohibits the Company from complying with the provisions of this Section 6.4), (2) any such non-public information has previously been made available to, or is made available to, Parent prior to or concurrently with (or in the case of oral non-public information only, promptly (and in any event within 24 hours) after) the time such information is made available to such Person, (3) prior to taking any such actions, the Company Board or any committee thereof determines in good faith, after consultation with its financial advisors and outside legal counsel, that such Company Competing Proposal is, or would reasonably be expected to lead to, a Company Superior Proposal and (4) prior to taking any such actions, the Company Board determines in good faith after consultation with its outside legal counsel that failure to take such action would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law;

A-41

(iii)   prior to, but not after, the receipt of the Company Stockholder Approval, in response to a bona fide written Company Competing Proposal from a third party that was not solicited at any time following the execution of this Agreement and did not arise from a material breach of the obligations set forth in this Section 6.4, if the Company Board so chooses, the Company Board may effect a Company Change of Recommendation (other than of the type described in clause (vi) of the definition thereof) or terminate this Agreement pursuant to and in accordance with Section 8.1(e) in order to enter into a definitive agreement with respect to such Company Superior Proposal; provided, however, that such a Company Change of Recommendation or termination of this Agreement, as applicable, may not be made unless and until:

(A)   the Company Board determines in good faith after consultation with its financial advisors and outside legal counsel that such Company Competing Proposal is a Company Superior Proposal;

(B)   the Company Board determines in good faith, after consultation with its outside legal counsel, that failure to effect a Company Change of Recommendation in response to such Company Superior Proposal or terminate this Agreement to enter into a definitive agreement with respect to such Company Superior Proposal would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law;

(C)   the Company provides Parent written notice of such proposed action and the basis thereof five (5) Business Days in advance, which notice shall set forth in writing that the Company Board intends to consider whether to take such action and include a copy of the available proposed Company Competing Proposal and any applicable transaction and financing documents;

(D)   after giving such notice and prior to effecting such Company Change of Recommendation or terminating this Agreement pursuant to Section 8.1(e), the Company negotiates (and causes its officers, employees, financial advisor and outside legal counsel to negotiate) in good faith with Parent (to the extent Parent wishes to negotiate) to make such adjustments or revisions to the terms of this Agreement as would permit the Company Board not to effect a Company Change of Recommendation or terminate this Agreeement in response thereto; and

(E)   at the end of the five (5) Business Day period, prior to taking action to effect a Company Change of Recommendation or terminating this Agreement pursuant to Section 8.1(e), the Company Board takes into account any adjustments or revisions to the terms of this Agreement proposed by Parent in writing and any other information offered by Parent in response to the notice, and determines in good faith after consultation with its financial advisors and outside legal counsel, that the Company Competing Proposal remains a Company Superior Proposal and that the failure to effect a Company Change of Recommendation in response to such Company Superior Proposal, or terminate this Agreement pursuant to Section 8.1(e) to enter into a definitive agreement with respect to such Company Superior Proposal, as applicable, would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law; provided, that in the event of any material amendment or material modification to any Company Superior Proposal (it being understood that any amendment or modification to the economic terms of any such Company Superior Proposal shall be deemed material), the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 6.4(e)(iii) with respect to such new written notice, except that the advance written notice obligation set forth in this Section 6.4(e)(iii) shall be reduced to three (3) Business Days; provided, further, that any such new written notice shall in no event shorten the original five (5) Business Day notice period; and

(iv)   prior to, but not after, receipt of the Company Stockholder Approval, in response to a Company Intervening Event that occurs or arises after the date of this Agreement and that did not arise from or in connection with a breach of this Agreement by the Company, the Company

A-42

may, if the Company Board so chooses, effect a Company Change of Recommendation; provided, however, that such a Company Change of Recommendation may not be made unless and until:

(A)   the Company Board determines in good faith after consultation with its financial advisors and outside legal counsel that a Company Intervening Event has occurred;

(B)   the Company Board determines in good faith, after consultation with its outside legal counsel, that failure to effect a Company Change of Recommendation in response to such Company Intervening Event would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law;

(C)   the Company provides Parent written notice of such proposed action and the basis thereof five (5) Business Days in advance, which notice shall set forth in writing that the Company Board intends to consider whether to take such action and includes a reasonably detailed description of the facts and circumstances of the Company Intervening Event;

(D)   after giving such notice and prior to effecting such Company Change of Recommendation, the Company negotiates (and causes its officers, employees, financial advisor and outside legal counsel to negotiate) in good faith with Parent (to the extent Parent wishes to negotiate) to make such adjustments or revisions to the terms of this Agreement as would permit the Company Board not to effect a Company Change of Recommendation in response thereto; and

(E)   at the end of the five (5) Business Day period, prior to taking action to effect a Company Change of Recommendation, the Company Board takes into account any adjustments or revisions to the terms of this Agreement proposed by Parent in writing and any other information offered by Parent in response to the notice, and determines in good faith after consultation with its financial advisors and outside legal counsel, that the failure to effect a Company Change of Recommendation in response to such Company Intervening Event would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law; provided, that in the event of any material changes regarding any Company Intervening Event, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 6.4(e)(iv) with respect to such new written notice, except that the advance written notice obligation set forth in this Section 6.4(e)(iv) shall be reduced to three (3) Business Days; provided, further, that any such new written notice shall in no event shorten the original five (5) Business Day notice period.

(f)   During the period commencing with the execution and delivery of this Agreement and continuing until the earlier of the Effective Time and termination of this Agreement in accordance with Article VIII, the Company shall not (and it shall cause its Subsidiaries not to) terminate, amend, modify or waive any provision of any confidentiality, “standstill” or similar agreement to which it or any of its Subsidiaries is a party; provided, that, notwithstanding any other provision in this Section 6.4, prior to, but not after, the time the Company Stockholder Approval is obtained, if, in response to an unsolicited request from a third party to waive any “standstill” or similar provision, the Company Board determines in good faith, after consultation with its outside legal counsel that the failure to take such action would be inconsistent with its fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law, the Company may waive any such “standstill” or similar provision solely to the extent necessary to permit a third party to make a Company Competing Proposal, on a confidential basis, to the Company Board and communicate such waiver to the applicable third party; provided, however, that the Company shall advise Parent at least two (2) Business Days prior to taking such action. The Company represents and warrants to Parent that it has not taken any action that (i) would be prohibited by this Section 6.4(f) or (ii) but for the ability to avoid actions inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law, would have been prohibited by this Section 6.4(f), in each case, during the thirty (30) days prior to the date of this Agreement.

(g)   Notwithstanding anything to the contrary in this Section 6.4, any action, or failure to take action, that is taken by a director or officer of the Company or any of its Subsidiaries or by any

A-43

Representative of the Company or its Subsidiaries acting at the Company’s direction or on its behalf, in each case, in violation of this Section 6.4, shall be deemed to be a breach of this Section 6.4 by the Company.

(a)   Parent and the Company will jointly prepare and cause to be filed with the SEC the Registration Statement (in which the Proxy Statement will be included) and the Proxy Statement and shall use commercially reasonable efforts to cause such filing to be made no later than thirty (30) days after the date hereof. The Company, Parent and Merger Sub shall cooperate with each other in the preparation of the Registration Statement and the Proxy Statement and furnish all information concerning itself and its Affiliates that is required in connection with the preparation of the Registration Statement or Proxy Statement and any amendments or supplements thereto. No filing of, or amendment or supplement to, the Registration Statement or Proxy Statement or response to SEC comments will be made by Parent or the Company without providing the other Party a reasonable opportunity to review and comment thereon and such Party shall give reasonable consideration to any comments made by the other Party and its Representatives; provided, that with respect to documents filed by a Party related to the Transactions which are incorporated by reference in the Registration Statement or Proxy Statement, the other Party’s right to comment shall not apply with respect to information (if any) relating to the filing Party’s business, financial condition or results of operations. Each of Parent and the Company shall use its commercially reasonable efforts to (i) cause the Registration Statement and the Proxy Statement at the date that it (and any amendment or supplement thereto) is first published, sent, or given to the holders of Company Common Stock and at the time of the Company Stockholders Meeting, to (A) comply as to form in all material respects with the requirements of the Securities Act and Exchange Act, respectively, and the rules and regulations promulgated thereunder and (B) not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading and (ii) have the Registration Statement declared effective under the Securities Act as promptly as practicable after its filing and keep the Registration Statement effective for so long as necessary to consummate the Merger.

(b)   Parent and the Company shall make all necessary filings with respect to the Merger and the Transactions under the Securities Act and the Exchange Act and applicable “blue sky” laws and the rules and regulations thereunder. Each Party will advise the other Party, promptly after it receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed or the issuance of any stop order or the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction. Each of the Company and Parent will use reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated.

(c)   If at any time prior to the Effective Time, Parent or the Company discovers any information relating to Parent or the Company, or any of their respective Affiliates, officers or directors that should be set forth in an amendment or supplement to the Registration Statement or the Proxy Statement, so that such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Party and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by applicable Law, disseminated to the stockholders of the Company.

6.6   Company Stockholders Meeting.

(a)   The Company shall take all action necessary in accordance with applicable Laws and the Organizational Documents of the Company to duly give notice of, convene and hold (in person or virtually, in accordance with applicable Law) a meeting of its stockholders for the purpose of obtaining the Company Stockholder Approval, to be held as promptly as reasonably practicable following the clearance of the Proxy Statement by the SEC and the Registration Statement is declared effective by the SEC (and in any event will use reasonable best efforts to convene such meeting within forty (40) days

A-44

thereof). Except as expressly permitted by Section 6.4, the Company Board shall recommend that the stockholders of the Company vote in favor of the adoption of this Agreement at the Company Stockholders Meeting and the Company Board shall solicit from stockholders of the Company proxies in favor of the adoption of this Agreement, and the Proxy Statement shall include the Company Board Recommendation. The Company shall not, without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), adjourn, postpone or otherwise delay the Company Stockholders Meeting; provided that the Company may, notwithstanding the foregoing, without the prior written consent of Parent, and shall if requested by Parent, adjourn or postpone the Company Stockholders Meeting (i) if, after consultation with Parent, the Company 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 Company Stockholder Approval, or (B) distribute any supplement or amendment to the Proxy Statement the distribution of which the Company 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, and the Company shall use its reasonable best efforts to obtain such a quorum as promptly as practicable. Notwithstanding the foregoing, (1) the Company may not, without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed) postpone or adjourn the Company Stockholder Meeting (x) more than a total of three (3) times pursuant to clause (i)(A) or (ii) of the immediately preceding sentence or (y) for a period exceeding ten (10) Business Days in the aggregate pursuant to clause (i)(A) or (ii) of the immediately preceding sentence; and (2) if the Company Stockholders Meeting is postponed or adjourned, the Company shall reconvene the Company Stockholders Meeting at the earliest practicable date on which the Company reasonably expects to have sufficient affirmative votes to obtain the Company Stockholder Approval; and provided, further that the Company Stockholders Meeting shall not be adjourned or postponed to a date on or after three (3) Business Days prior to the End Date. If requested by Parent, the Company shall promptly provide all voting tabulation reports relating to the Company Stockholders Meeting that have been prepared by the Company or the Company’s transfer agent, proxy solicitor or other Representative, and shall otherwise keep Parent reasonably informed regarding the status of the solicitation and any material oral or written communications from or to the Company’s stockholders with respect thereto. Unless there has been a Company Change of Recommendation in accordance with Section 6.4, the Parties agree to cooperate and use their reasonable best efforts to defend against any efforts by any of the Company’s stockholders or any other Person to prevent the Company Stockholder Approval from being obtained.

(b)   The Company will, as soon as reasonably practicable following the date of this Agreement, establish a record date (and commence a broker search pursuant to Section 14a-13 of the Exchange Act in connection therewith), which record date shall be prior to (or as promptly as reasonably practicable following) the effectiveness of the Registration Statement. Once the Company has established a record date for the Company Stockholders Meeting, the Company shall not change such record date or establish a different record date for the Company Stockholders Meeting without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed), unless required to do so by applicable Law or its Organizational Documents.

(c)   Without the prior written consent of Parent or as required by applicable Law, (i) the adoption of this Agreement shall be the only matter (other than a non-binding advisory proposal regarding compensation that may be paid or become payable to the named executive officers of the Company in connection with the Merger and matters of procedure) that the Company shall propose to be acted on by the stockholders of the Company at the Company Stockholders Meeting and the Company shall not submit any other proposal to such stockholders in connection with the Company Stockholders Meeting or otherwise (including any proposal inconsistent with the adoption of this Agreement or the consummation of the Transactions) and (ii) the Company shall not call, hold or convene any meeting of the stockholders of the Company other than the Company Stockholders Meeting and the regular annual meeting of stockholders of the Company for 2025 and 2026 (provided that (x) the proposals presented at any such annual stockholders’ meeting are the same as those customarily presented by the Company at its annual stockholders’ meetings, and (y) the Company does not present any proposal at any such annual stockholders’ meeting that would violate the terms of this Agreement or would

A-45

reasonably be expected to materially delay, materially impede or prevent the consummation of the Merger or the other transactions contemplated by this Agreement).

(d)   Without limiting the generality of the foregoing, the Company agrees that (x) its obligations pursuant to this Section 6.6 shall not be affected by the commencement, announcement, disclosure, or communication of any Company Competing Proposal or other proposal (including a Company Superior Proposal) or the occurrence or disclosure of any Company Intervening Event, and (y) prior to the valid termination of this Agreement pursuant to Article VIII, its obligations to hold the Company Stockholders Meeting pursuant to this Section 6.6 shall not be affected by the making of a Company Change of Recommendation.

(e)   Promptly after the execution of this Agreement, Parent shall duly approve and adopt this Agreement in its capacity as the sole stockholder of Merger Sub in accordance with applicable Law and the Organizational Documents of Merger Sub and deliver to the Company evidence of its vote or action by written consent so approving and adopting this Agreement.

6.7   Access to Information.

(a)   Subject to applicable Law, Section 6.8(c) and the other provisions of this Section 6.7, the Company shall (and shall cause its Subsidiaries to), upon request by Parent, furnish Parent with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any statement, filing, notice or application made by or on behalf of Parent or any of its Subsidiaries to any third party or any Governmental Entity in connection with the Transactions. The Company shall, and shall cause each of its Subsidiaries to, afford to Parent and its Representatives, during the period prior to the earlier of the Effective Time and the termination of this Agreement in accordance with Article VIII, reasonable access, at reasonable times upon reasonable prior notice, to the officers, key employees, agents, properties, offices and other facilities of the Company and its Subsidiaries and to their books, records, contracts and documents and shall, and shall cause each of its Subsidiaries to, furnish reasonably promptly to Parent and its Representatives such information concerning its and its Subsidiaries’ business, properties, contracts, records and personnel as may be reasonably requested, from time to time, by or on behalf of Parent. Parent and its Representatives shall conduct any such activities in such a manner as not to interfere unreasonably with the business or operations of the Company or its Subsidiaries or otherwise cause any unreasonable interference with the prompt and timely discharge by the employees of the Company and its Subsidiaries of their normal duties. Notwithstanding the foregoing:

(i)   the Company shall not be required to, or to cause any of its Subsidiaries to, grant access or furnish information, as applicable, to Parent or any of its Representatives to the extent that such information is subject to an attorney/client privilege or the attorney work product doctrine or that such access or the furnishing of such information, as applicable, is prohibited by applicable Law or an existing contract or agreement (provided, however, that the Company shall inform Parent as to the general nature of what is being withheld and the Company shall reasonably cooperate with Parent to make appropriate substitute arrangements to permit reasonable disclosure that does not suffer from any of the foregoing impediments, including through the use of commercially reasonable efforts to (A) obtain the required consent or waiver of any third party required to provide such information and (B) implement appropriate and mutually agreeable measures to permit the disclosure of such information in a manner to remove the basis for the objection, including by arrangement of appropriate clean room procedures, redaction or entry into a customary joint defense agreement with respect to any information to be so provided, if the Parties determine that doing so would reasonably permit the disclosure of such information without violating applicable Law or jeopardizing such privilege);

(ii)   Parent shall not be permitted to conduct any sampling or analysis of any environmental media or building materials at any facility of the Company or its Subsidiaries without the prior written consent of the Company (granted or withheld in its sole discretion); and

(iii)   no investigation or information provided pursuant to this Section 6.7 shall affect or be deemed to modify any representation or warranty made by the Company or to operate as a non-compete obligation against Parent and its Subsidiaries.

A-46

(b)   The Confidentiality Agreement dated as of May 10, 2024 between Parent and the Company (the “Confidentiality Agreement”) shall survive the execution and delivery of this Agreement and shall apply to all information furnished thereunder or hereunder; provided, that section 8 of the Confidentiality Agreement shall be of no force and effect as of the date hereof. From and after the date of this Agreement until the earlier of the Effective Time and termination of this Agreement in accordance with Article VIII, each Party shall continue to provide access to the other Party and its Representatives to the data relating to the Transactions maintained by or on its behalf to which the other Party and its Representatives were provided access prior to the date of this Agreement.

6.8   HSR and Other Approvals.

(a)   Except for the filings and notifications made pursuant to Antitrust Laws to which Sections 6.8(b) through 6.8(e), and not this Section 6.8(a), shall apply, promptly following the execution of this Agreement, the Parties shall proceed to prepare and file with the appropriate Governmental Entities and other third parties all authorizations, consents, notifications, certifications, registrations, declarations and filings that are necessary in order to consummate the Transactions and shall diligently and expeditiously prosecute, and shall cooperate fully with each other in the prosecution of, such matters. Notwithstanding the foregoing (but subject to Sections 6.8(b) and 6.8(e)), in no event shall either the Company or Parent or any of their respective Affiliates be required to pay any consideration to any third parties or give anything of value to obtain any such Person’s authorization, approval, consent or waiver to effectuate the Transactions, other than filing, recordation or similar fees, provided, that the Company shall take such actions if requested by Parent so long as such actions are conditioned on the occurrence of the Closing and Parent has agreed to reimburse the Company for its reasonable out-of-pocket costs in connection with such actions in the event that the Closing does not occur. Parent and the Company shall have the right to review in advance and each will consult with the other on and consider in good faith the views of the other in connection with, all of the information relating to Parent or the Company, as applicable, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the Transactions (including the Registration Statement and Proxy Statement). The Company and its Subsidiaries shall not agree to any actions, restrictions or conditions with respect to obtaining any consents, registrations, approvals, permits, expirations of waiting periods or authorizations in connection with the Transactions without the prior written consent of Parent (which consent, subject to Section 6.8(b), may be withheld in Parent’s sole discretion).

(b)   As promptly as reasonably practicable following the execution of this Agreement, (x) the Parties shall file, or cause to be filed all required Notification and Report Forms under the HSR Act with respect to this Agreement and the Transactions (which shall be filed no later than ten (10) Business Days following the date of this Agreement, provided that there are no changes in effect in the applicable regulations under the HSR Act between the date hereof and the date of filing pursuant to the HSR Act, in which instance the Company and Parent shall use reasonable best efforts to file or cause to be filed any and all required notification and report forms under the HSR Act as promptly as commercially practicable thereafter); and (y) Parent shall, at its own cost, and with the cooperation and support of the Company and its Subsidiaries, file, or cause to be filed any required merger notifications in connection with the Specified Regulatory Approvals (which shall be filed no later than twenty (20) Business Days following the date of this Agreement). Each of Parent and the Company shall cooperate fully with each other and shall furnish to the other such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of any filings under any applicable Antitrust Laws. Unless otherwise agreed, Parent and the Company shall each use its reasonable best efforts to ensure the prompt expiration or termination of any applicable waiting period under the HSR Act, ensure the prompt receipt of the Specified Regulatory Approvals or the expiration or lapse of any legislated review periods (including any extensions thereof) in the jurisdictions where Specified Regulatory Approvals are sought (as applicable), and bring about the Closing as promptly as practicable. Parent and the Company shall each use its reasonable best efforts to respond to and comply with any request for information or documentary materials from any Governmental Entity (“Antitrust Authority”) charged with enforcing, applying, administering, or investigating the HSR Act or any other Law designed to govern competition, trade or foreign investment, or to prohibit, restrict or regulate actions with the

A-47

purpose or effect of monopolization, restraint of trade, lessening of competition, or foreign investment for the purpose of national security, public order, or defense matters (collectively, “Antitrust Laws”).

(c)   Each Party shall: (i) promptly notify the other Parties of, and if in writing, furnish the others with copies of (or, in the case of oral communications, advise the others of the contents of) any communication to such Person from an Antitrust Authority or other Governmental Entity and permit the others to review and discuss in advance (and to consider in good faith any comments made by the others in relation to) any proposed written communication to an Antitrust Authority or other Governmental Entity, (ii) keep the others informed of any developments, meetings or discussions with any Antitrust Authority or other Governmental Entity in respect of any filings, investigation, or inquiry concerning the Transactions and (iii) not independently participate in any meeting or discussions with an Antitrust Authority or other Governmental Entity in respect of any filings, investigation or inquiry concerning the Transactions without giving the other parties prior notice of such meeting or discussions and, unless prohibited by such Antitrust Authority or other Governmental Entity, the opportunity to attend or participate. However, (A) each of Parent and the Company may designate any non-public information provided to any Antitrust Authority or other Governmental Entity as restricted to “Outside Antitrust Counsel Only” and any such information shall not be shared with employees, officers, managers or directors or their equivalents of the other Parties hereto without approval of the Party providing the non-public information, and (B) materials may be redacted (x) to remove references concerning the valuation of the Company, (y) as necessary to comply with contractual arrangements and (z) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns.

(d)   In furtherance of the foregoing, Parent shall take any and all actions necessary, including but not limited to (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets, or businesses of the Company or Parent or their respective Subsidiaries; (ii) terminating, transferring or creating any existing relationships, contractual rights or obligations of the Company or Parent or their respective Subsidiaries; (iii) terminating any venture or other arrangement; (iv) creating any relationship, contractual rights or obligations of the Company or Parent or their respective Subsidiaries, or accepting any restriction on Parent’s freedom of action following the Closing; or (v) effectuating any other change or restructuring of the Company or Parent or their respective Subsidiaries (and, in each case, Parent shall enter into agreements or stipulate to the entry of an order or decree or file appropriate applications with any Antitrust Authority in connection with any of the foregoing) (each a “Divestiture Action”) to avoid the entry of or effect the dissolution of any Law preliminarily or permanently restraining, enjoining or prohibiting the consummation of the Merger, or to ensure the expiration or termination of the waiting period under the HSR Act, and to receive the Specified Regulatory Approvals, as promptly as reasonably practicable; provided, however, that, notwithstanding any other provisions of this Agreement, neither Parent nor any of its Subsidiaries shall be required to (1) take or agree to take (and, without the express prior written consent of Parent, the Company and its Subsidiaries shall not take or agree to take) any Divestiture Action or other action that would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, financial condition or operations of Parent and its Subsidiaries from and after the Effective Time (but, for purposes of determining whether any effect is material, calculated as if Parent and its Subsidiaries from and after the Effective Time were collectively the same size as Company and its Subsidiaries as of the date of this Agreement), taken as a whole or (2) agree to or otherwise accept a requirement for Parent or any of its Subsidiaries (including at or after the Closing, the Company and any of its Subsidiaries) to provide prior notice to, or obtain prior approval from, any Antitrust Authority or other Governmental Entity, provided, that subject to and as specified in Schedule 6.8(d) of the Company Disclosure Letter, Parent shall, if required by any applicable Antitrust Authority or other Governmental Entity, agree to any requirement to provide prior notice to, or to obtain prior approval from, any Antitrust Authority or other Governmental Entity to the extent such requirement is immaterial to Parent. Notwithstanding any other provisions of this Section 6.8, nothing in this Agreement shall require Parent to take or agree to take any Divestiture Action or other action (other than de minimis actions) with respect to Parent and its Subsidiaries (other than with respect to the Company and its Subsidiaries (from and after the Effective Time)). The Company shall agree to take any Divestiture Action requested by Parent if such actions are only effective after the Effective Time and conditioned upon the Closing. In the event that any Divestiture Action is proposed by or acceptable to a Governmental Entity, Parent shall have the right to determine the manner in which to implement the requirement of

A-48

such Governmental Entity; provided, that in no event shall Parent or the Company (or any of their respective Subsidiaries or other Affiliates) be required to take or effect any Divestiture Action that is not conditioned upon the Closing. In the event that any action is threatened or instituted challenging the Merger as violative of any Antitrust Law, Parent and the Company shall cooperate with each other to avoid, contest or resist (as applicable) any such litigation, action or proceeding and to have vacated lifted, reversed or overturned as promptly as practicable any Law that is in effect and that prohibits, prevents or restricts consummation of the Merger, in each case so as bring about the Closing as promptly as practicable and in any event no later than the End Date. The Parties shall jointly determine the strategy to be pursued in seeking to remove impediments to the Closing related to Antitrust Laws and jointly direct any related Proceedings with any Antitrust Authority, Governmental Entity or other Person, provided, however, in the event of a disagreement between the Parties relating to any of the foregoing, that Parent, subject to its obligations in this Section 6.8, and, after considering the views of the Company in good faith, shall be entitled to make the final determination of the approach to be pursued by the Parties.

(e)   Parent and the Company shall not, and each of Parent and the Company shall cause their respective Subsidiaries to not, acquire or agree to acquire any other Person or business or any assets or properties of any other Person if such acquisition would reasonably be expected to materially impede, prevent or materially delay the expiration or termination of the waiting period under the HSR Act, receipt of the Specified Regulatory Approvals, or the Closing.

6.9   Employee Matters.

(a)   The following provisions shall apply with respect to the compensation and benefits to be provided after the Effective Time in respect of each individual who is employed as of the Effective Time by the Company or a Subsidiary thereof (a “Company Employee”):

(i)   The Company and Parent have agreed that, consistent with the current practices of the Company and Parent, the Company and Parent will seek after the Effective Time to attract and retain superior quality executive, managerial, technical and administrative personnel in every market in which they conduct activities and will generally implement compensation and benefit plans and policies necessary or appropriate to achieve this objective. It is the specific intention that, in each of the markets in which they operate, the compensation and benefit programs of the Company and Parent will be competitive with those provided generally in their industry, both with respect to the type and variety of programs as well as the level of benefits afforded.

(ii)   Without limiting the generality of clause (i) above, except as otherwise expressly set forth herein, and subject to applicable Law and any obligations under any collective bargaining agreement, the Company and Parent agree that, until the first anniversary of the Closing Date, Parent shall cause each Company Employee who remains employed by Parent or any of its Subsidiaries (including the Surviving Corporation or any of its Subsidiaries) to be provided with (A) base compensation (salary or wages, as applicable) and post-termination severance pay, in each case, not less than the level in effect for such Company Employee as of immediately prior to the Effective Time, (B) target annual cash incentive compensation opportunities and target long-term incentive (equity-based) compensation opportunities each not less than that in effect for such Company Employee as of immediately prior to the Effective Time, and (C) employee benefits (including defined benefit retirement plan participation under the cash balance portion of the Company Retirement Plan and defined contribution retirement plan participation but excluding any other defined benefit pension and any change in control and other severance benefits) that are substantially comparable in the aggregate to those provided to such Company Employee immediately prior to the Effective Time; provided that Parent agrees to maintain the following benefits without reduction or any other material changes except as required for compliance with tax qualification or other requirements under applicable Law: (I) for the period beginning at the Closing Date and ending on the first anniversary of the Closing Date, defined benefit pension benefits under the cash balance portion of the Company Retirement Plan; and (II) for the period beginning at the Closing Date and ending on December 31, 2025, retiree health and life insurance benefits for those individuals who are participants in the Company’s or its Subsidiary’s retiree health and life insurance benefits as of immediately prior to the Effective Time and individuals who

A-49

become eligible to participate in such retiree health and life insurance benefits during the period beginning at the Closing Date and ending on December 31, 2025. For each Company Employee covered by a change in control severance plan of the Company or any of its Subsidiaries immediately prior to the Effective Time, such coverage shall continue in accordance with the terms of such plan immediately prior to the Effective Time until the first to occur of (x) the employee’s separation from service, (y) the employee’s voluntary waiver of such benefit, and (z) the second anniversary of the Closing Date.

(b)   From and after the Effective Time, Parent shall, or shall cause the Surviving Corporation and its Subsidiaries, as applicable, to credit the Company Employees for purposes of vesting and eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies and disability plans and policies, determining levels of benefits under the Parent Plans (other than to the extent it would result in a duplication of benefits) in which the Company Employees may be eligible to participate after the Effective Time, for such Company Employees’ service with the Company and its Subsidiaries, to the same extent and for the same purposes that such service was taken into account under a corresponding Company Plan immediately prior to the Effective Time.

(c)   From and after the Effective Time, Parent shall, or shall cause the Surviving Corporation and its Subsidiaries, as applicable, to take commercially reasonable efforts to (i) cause each Company Employee to be immediately eligible to participate, without any waiting time, in any and all Parent Plans to the extent coverage under such Parent Plan replaces coverage under the comparable Company Plan in which such Company Employee participated immediately prior to the Effective Time, (ii) waive any limitation on health and welfare coverage of any Company Employee and his or her eligible dependents due to pre-existing conditions and/or waiting periods, active employment requirements and requirements to show evidence of good health under the applicable health and welfare Parent Plan to the extent such Company Employee and his or her eligible dependents are covered under a Company Plan immediately prior to the Effective Time, and such conditions, periods or requirements were satisfied or waived under such Company Plan and (iii) give each Company Employee credit for the plan year in which the Closing Date occurs towards applicable deductibles, coinsurance and annual out-of-pocket limits for expenses incurred prior to the Closing Date for which payment has been made under the applicable Company Plan for purposes of satisfying all deductibles, coinsurance and annual out-of-pocket limits applicable to such Company Employee and his or her eligible dependents under the applicable Parent Plan for the applicable plan year as if such amounts had been paid in accordance with such Parent Plan.

(d)   Except as otherwise expressly provided in this Agreement, from and after the Effective Time, Parent shall honor, and shall cause its Subsidiaries (including the Surviving Corporation) to honor, in accordance with its terms (including terms related to the amendment or termination thereof), the Company Plans and each employment, severance, retention, change in control and termination arrangement between the Company or any of its Subsidiaries, and any current or former officer, director or employee of any such company, to the extent such terms are in effect on the date hereof.

(e)   It is acknowledged and agreed that the consummation of the transactions contemplated hereby will constitute a “change of control” ​(or “change in control” or transaction of similar import) for purposes of all Company Plans, policies, programs or agreements (including, but not limited to severance plans and award agreements under the Company Stock Plan that include the term “change in control” or “change of control”, as applicable).

(f)   To the extent permitted by applicable Law, the Company shall provide Parent with a true, complete and correct list of the following with respect to (i) each employee of the Company or a Subsidiary thereof: name, employer, title, hire date, work location, whether full- or part-time, whether active or on leave (and, if on leave, the nature of the leave and the expected return date), service dates (rehire date, vacation eligibility date, service credit date, if different from initial date of hire, and experience date), visa requirements, name of person to whom each employee reports, current detailed organization chart of employees, eligibility for any location premiums, eligibility for legacy retirement benefit, eligibility for retiree medical benefits, whether exempt from the Fair Labor Standards Act, annual salary or wage rate, most recent annual bonus and long-term incentive grant received and current annual bonus opportunity and long-term incentive opportunity, which shall be provided not later

A-50

than thirty (30) Business Days following the date of this Agreement; (ii) each former employee of the Company or a Subsidiary thereof currently receiving or eligible to receive retiree health and welfare benefits: name, retirement date, expected date retiree coverage will end, and coverage level, which shall be provided not later than thirty (30) Business Days following the date of this Agreement; and (iii) each individual independent contractor whose engagement involves providing material services to the Company: name, entity for which services are provided, services provided, service commencement date, rate of compensation and scheduled termination date, which shall be provided not later than thirty (30) Business Days following the date of this Agreement.

(g)   Nothing in this Agreement shall constitute an amendment to, or be construed as amending, any Company Plan or any Parent Plan or any other benefit or compensation plan, program, policy, agreement or arrangement sponsored, maintained or contributed to by the Company, Parent or any of their respective Subsidiaries. The provisions of this Section 6.9 are for the sole benefit of the Parties and nothing herein, expressed or implied, is intended or will be construed to confer upon or give to any Person (including, for the avoidance of doubt, any Company Employee or other current or former employee of the Company or any of their respective Affiliates), other than the Parties and their respective permitted successors and assigns, any third-party beneficiary, legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 6.9) under or by reason of any provision of this Agreement. Nothing in this Agreement is intended to prevent Parent, the Surviving Corporation or any of their Affiliates (i) from amending or terminating any of their respective Employee Benefit Plans or, after the Effective Time, any Company Plan in accordance with their terms or any other benefit or compensation plan, program, policy, agreement or arrangement (ii) after the Effective Time, from terminating the employment of any Company Employee.

(i)   For six (6) years after the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation shall indemnify, defend and hold harmless (and advance expenses in connection therewith, subject to a customary undertaking from the applicable Indemnified Person to return such advances if it is determined by the final adjudication of a court of law that the Indemnified Person is not entitled to indemnification hereunder) the present and former directors, officers, employees, fiduciaries and agents of the Company and its Subsidiaries, and any individuals serving in such capacity at or with respect to other Persons at the Company’s or its Subsidiaries’ request (each, an “Indemnified Person”) from and against any losses, claims, damages, liabilities, costs, expenses (including attorneys’ fees), judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect thereof) in respect of the Indemnified Persons having served in such capacity at or prior to the Effective Time, in each case, to the fullest extent permitted by the DGCL or provided under the Organizational Documents of the Company and its Subsidiaries in effect on the date hereof. If any Indemnified Person is made party to any Proceeding arising out of or relating to matters that would be indemnifiable pursuant to the immediately preceding sentence, the Surviving Corporation shall advance fees, costs and expenses (including attorneys’ fees and disbursements) as incurred by such Indemnified Person in connection with and prior to the final disposition of such claim, action, suit, proceeding or investigation in each case to the extent the Company is required to do so and on the same terms as provided in the Organizational Documents of the Company and its Subsidiaries in effect on the date hereof; provided that any Indemnified Person wishing to claim indemnification or advancement of expenses under this Section 6.10, upon learning of any such Proceeding, shall notify the Surviving Corporation (but the failure so to notify shall not relieve the Surviving Corporation from any obligations that it may have under this Section 6.10 except to the extent such failure materially prejudices such party’s position with respect to such claims); and

(ii)   For six (6) years after the Effective Time, Parent shall cause the Surviving Corporation to maintain in effect provisions in the Organizational Documents of the Surviving Corporation

A-51

and its Subsidiaries (or in such documents of any successor to the business thereof) regarding elimination of liability of directors and officers, indemnification of officers, directors, employees, fiduciaries and agents and advancement of fees, costs and expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence on the date of this Agreement.

(c)   For six (6) years after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to honor and comply with their respective obligations under any indemnification agreement with any Indemnified Person that is set forth in Schedule 6.10(b) of the Company Disclosure Letter, and not amend, repeal or otherwise modify any such agreement in any manner that would materially and adversely affect any right of any Indemnified Person thereunder.

(d)   Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the non-cancellable extension of the directors’ and officers’ liability coverage of the Company’s existing directors’ and officers’ insurance policies and the Company’s existing fiduciary liability insurance policies (collectively, “D&O Insurance”), which D&O Insurance shall (i) be for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time, (ii) be from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to D&O Insurance and (iii) have terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company’s existing policies with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against an Indemnified Person by reason of him or her having served in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the Transactions); provided that the Company shall give Parent a reasonable opportunity to participate in the selection of such tail policy and the Company shall give reasonable and good faith consideration to any comments made by Parent with respect thereto; provided, further that the cost of any such tail policy shall not exceed 350% of the aggregate annual premium paid by the Company in respect of the D&O Insurance (which amount is set forth in Schedule 6.10(d) of the Company Disclosure Letter); and provided, further, that if the aggregate premiums of such tail policy exceed such amount, the Company shall, or Parent shall cause the Surviving Corporation to, as applicable, obtain a policy with the greatest coverage available, with respect to matters occurring prior to the Effective Time, for a cost not exceeding such amount.

(f)   The rights of each Indemnified Person under this Section 6.10 shall be in addition to any rights such Person may have under the Organizational Documents of the Company or any of its Subsidiaries under the DGCL or any other applicable Law or under any agreement of any Indemnified Person with the Company or any of its Subsidiaries that is set forth in Schedule 6.10(b) of the Company Disclosure Letter.

6.11   Transaction Litigation.   In the event any Proceeding by any stockholder of the Company or Parent is commenced or, to the knowledge of the Company or Parent, as applicable, threatened, that questions the validity or legality of the Transactions or seeks damages in connection therewith (“Transaction Litigation”), the Company or Parent, as applicable, shall promptly notify the other Party of such Transaction Litigation and shall keep the other Party reasonably informed with respect to the status thereof. The Company shall give Parent a reasonable opportunity to participate in the defense or settlement of any

A-52

Transaction Litigation and shall consult regularly with Parent in good faith and give reasonable consideration to Parent’s advice with respect to such Transaction Litigation; provided, that the Company shall not cease to defend, consent to the entry of any judgment, settle or offer to settle any Transaction Litigation without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

(e)   In no event shall Parent be entitled to receive more than one (1) payment of the Company Termination Fee or more than one (1) payment of Parent Expenses. If Parent receives the Company Termination Fee, then Parent will not be entitled to also receive a payment of the Parent Expenses; upon payment of any Company Termination Fee, any previously paid Parent Expenses shall be credited against the amount of the Company Termination Fee. The Parties agree that the agreements contained

A-61

in this Section 8.3 are an integral part of the Transactions, and that, without these agreements, the Parties would not enter into this Agreement. The Parties also agree that the Company Termination Fee and Parent Expenses are liquidated damages and not penalties, and the payment of the Company Termination Fee and/or Parent Expenses in the circumstances specified herein is supported by due and sufficient consideration. If the Company or Parent fails to promptly pay the amount due by it pursuant to this Section 8.3, interest shall accrue on such amount from the date such payment was required to be paid pursuant to the terms of this Agreement until the date of payment at the rate of 8% per annum. If, in order to obtain such payment, the Company or Parent, as applicable, commences a Proceeding that results in judgment for the Company or Parent, as applicable, then Parent or the Company, as applicable, shall pay the Company or Parent, as applicable, its reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such Proceeding. The Parties agree that the monetary remedies set forth in this Section 8.3 and the specific performance remedies set forth in Section 9.11 shall be the sole and exclusive remedies of Parent and Merger Sub against the Company and its Subsidiaries and any of their respective former, current or future directors, officers, shareholders, Representatives or Affiliates for any loss suffered as a result of the failure of the Merger to be consummated, except in the case of fraud or a Willful and Material Breach of any covenant, agreement or obligation (in which case only the Company shall be liable for damages for such fraud or Willful and Material Breach), and upon payment of such amount, none of the Company and its Subsidiaries or any of their respective former, current or future directors, officers, shareholders, Representatives or Affiliates shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions, except for the liability of the Company in the case of fraud or a Willful and Material Breach of any covenant, agreement or obligation.

9.4   Rules of Construction.

(a)   Each of the Parties acknowledges that it has been represented by counsel of its choice throughout all negotiations that have preceded the execution of this Agreement and that it has executed the same with the advice of said independent counsel. Each Party and its counsel cooperated in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged between the Parties shall be deemed the work product of the Parties and may not be construed against any Party by reason of its preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any Party that drafted it is of no application and is hereby expressly waived.

(b)   The inclusion of any information in the Company Disclosure Letter or Parent Disclosure Letter shall not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, that such information is required to be listed in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, that such items are material to the Company and its Subsidiaries, taken as a whole, or Parent and its Subsidiaries, taken as a whole, as the case may be, or that such items have resulted in a Company Material Adverse Effect or a Parent Material Adverse Effect, as applicable. The headings, if any, of the individual sections of each of the Parent Disclosure Letter and the Company Disclosure Letter are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Letter and Parent Disclosure Letter are arranged in sections corresponding to the Sections of this Agreement merely for convenience, and the disclosure of an item in one section of the Company Disclosure Letter or Parent Disclosure Letter, as applicable, as an exception to a particular representation or warranty shall be deemed adequately disclosed as an exception with respect to all other representations or warranties to the extent that the relevance of such item to such representations or warranties is reasonably apparent on its face, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Letter or Parent Disclosure Letter with respect to such other representations or warranties or an appropriate cross reference thereto.

(c)   The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the Company Disclosure Letter or Parent Disclosure Letter is not intended and

A-63

shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the Parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

(d)   All references in this Agreement to Annexes, Exhibits, Schedules, Articles, Sections, subsections and other subdivisions refer to the corresponding Annexes, Exhibits, Schedules, Articles, Sections, subsections and other subdivisions of this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections, subsections or other subdivisions of this Agreement are for convenience only, do not constitute any part of such Articles, Sections, subsections or other subdivisions, and shall be disregarded in construing the language contained therein. The words “this Agreement,” “herein,” “hereby,” “hereunder” and “hereof” and words of similar import, refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The words “this Section,” “this subsection” and words of similar import, refer only to the Sections or subsections hereof in which such words occur. The word “including” ​(in its various forms) means “including, without limitation.” Pronouns in masculine, feminine or neuter genders shall be construed to state and include any other gender and words, terms and titles (including terms defined herein) in the singular form shall be construed to include the plural and vice versa, unless the context otherwise expressly requires. Unless the context otherwise requires, all defined terms contained herein shall include the singular and plural and the conjunctive and disjunctive forms of such defined terms. Unless the context otherwise requires, all references to a specific time shall refer to Houston, Texas time. The word “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply “if.” The term “dollars” and the symbol “$” mean United States Dollars. The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof.

(e)   In this Agreement, except as the context may otherwise require, references to: (i) any agreement (including this Agreement), contract, statute or regulation are to the agreement, contract, statute or regulation as amended, modified, supplemented, restated or replaced from time to time (in the case of an agreement or contract, to the extent permitted by the terms thereof and, if applicable, by the terms of this Agreement); (ii) any Governmental Entity includes any successor to that Governmental Entity; (iii) any applicable Law refers to such applicable Law as amended, modified, supplemented or replaced from time to time (and, in the case of statutes, include any rules and regulations promulgated under such statute) and references to any section of any applicable Law or other law include any successor to such section; (iv) “days” means calendar days; when calculating the period of time within which, or following which, any act is to be done or step taken pursuant to this Agreement, the date that is the reference day in calculating such period shall be excluded and if the last day of the period is a non-Business Day, the period in question shall end on the next Business Day or if any action must be taken hereunder on or by a day that is not a Business Day, then such action may be validly taken on or by the next day that is a Business Day; and (v) “made available” means, with respect to any document, that such document was previously made available in the electronic dataroom relating to the Transactions maintained by the Company or Parent, as applicable, or in the Company SEC Documents or Parent SEC Documents, on or prior to two (2) calendar days prior to the date of execution of this Agreement.

9.5   Counterparts.   This Agreement may be executed in two (2) or more counterparts, including via facsimile or email in “portable document format” ​(“.pdf”) form transmission, all of which shall be considered one and the same agreement and shall become effective when two (2) or more counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need not sign the same counterpart.

9.6   Entire Agreement; No Third-Party Beneficiaries.   This Agreement (together with the Confidentiality Agreement and any other documents and instruments executed pursuant hereto) constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. The Company Disclosure Letter and the Parent Disclosure Letter are “facts ascertainable” as that term is used in Section 251(b) of the DGCL, and do not form part of this Agreement but instead operate upon the terms of this Agreement as provided herein. Except

A-64

for the provisions of (a) Article III (including, for the avoidance of doubt, the rights of the former holders of Company Common Stock to receive the Merger Consideration) but only from and after the Effective Time and (b) Section 6.10 (which from and after the Effective Time is intended for the benefit of, and shall be enforceable by, the Persons referred to therein and by their respective heirs and Representatives) but only from and after the Effective Time, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the Parties any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

9.7   Governing Law; Venue; Waiver of Jury Trial.

(a)   THIS AGREEMENT, AND ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT) THAT MAY BE BASED UPON, ARISE OUT OF RELATE TO THIS AGREEMENT, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICTS OF LAW THEREOF.

THE PARTIES HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN SECTION 9.3 OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF.

(c)   EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 9.7.

A-65

9.8   Severability.   Each Party agrees that, should any court or other competent authority hold any provision of this Agreement or part hereof to be invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such other term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the greatest extent possible.

9.9   Assignment.   Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties (whether by operation of Law or otherwise) without the prior written consent of the other Party. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns. Any purported assignment in violation of this Section 9.9 shall be void.

9.10   Affiliate Liability.   Each of the following is herein referred to as a “Company Affiliate”: (a) any direct or indirect holder of equity interests or securities in the Company (whether stockholders or otherwise), and (b) any director, officer, employee, Representative or agent of (i) the Company or (ii) any Person who controls the Company. No Company Affiliate shall have any liability or obligation to Parent or Merger Sub of any nature whatsoever in connection with or under this Agreement or the transactions contemplated hereby or thereby other than for fraud, and Parent and Merger Sub hereby waive and release all claims of any such liability and obligation, other than for fraud. Each of the following is herein referred to as a “Parent Affiliate”: (x) any direct or indirect holder of equity interests or securities in Parent (whether stockholders or otherwise), and (y) any director, officer, employee, Representative or agent of (i) Parent or (ii) any Person who controls Parent. No Parent Affiliate shall have any liability or obligation to the Company of any nature whatsoever in connection with or under this Agreement or the transactions contemplated hereby or thereby other than for fraud, and the Company hereby waives and releases all claims of any such liability and obligation, other than for fraud.

9.11   Specific Performance.   The Parties agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the Parties. Prior to the termination of this Agreement pursuant to Section 8.1, it is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, in each case in accordance with this Section 9.11, this being in addition to any other remedy to which they are entitled under the terms of this Agreement at law or in equity. Each Party accordingly agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such Party under this Agreement all in accordance with the terms of this Section 9.11. Each Party further agrees that no other Party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 9.11, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. If prior to the End Date, any Party hereto brings an action to enforce specifically the performance of the terms and provisions hereof by any other Party, the End Date shall automatically be extended by such other time period established by the court presiding over such action. Notwithstanding anything herein to the contrary, while the Company may pursue both a grant of specific performance to the extent expressly permitted by this Section 9.11 and the payment of monetary damages, under no circumstances shall Parent or Merger Sub be obligated to both specifically perform the terms of this Agreement and pay monetary damages.

9.12   Amendment.   This Agreement may be amended by the Parties at any time before or after adoption of this Agreement by the stockholders of the Company, but, after any such adoption, no amendment shall be made which by Law or the rules of the NYSE would require the further approval by such stockholders without first obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

A-66

9.13   Extension; Waiver.   At any time prior to the Effective Time, the Company and Parent may, to the extent legally allowed:

(a)   extend the time for the performance of any of the obligations or acts of the other Party hereunder;

(b)   waive any inaccuracies in the representations and warranties of the other Party contained herein or in any document delivered pursuant hereto; or

(c)   waive compliance with any of the agreements or conditions of the other Party contained herein.

Notwithstanding the foregoing, no failure or delay by the Company or Parent in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. No agreement on the part of a Party to any such extension or waiver shall be valid unless set forth in an instrument in writing signed on behalf of such Party.

EXECUTION VERSION​

Board of Directors
Marathon Oil Corporation
900 Town and Country Boulevard
Houston, TX 77024

Members of the Board:

We understand that Marathon Oil Corporation (the “Company”), ConocoPhillips (the “Parent”), and Puma Merger Sub Corp., a wholly owned subsidiary of the Parent (“Merger Sub”), propose to enter into an Agreement and Plan of Merger, substantially in the form of the draft dated May 28, 2024 (the “Merger Agreement”), which provides, among other things, for the merger (the “Merger”) of Merger Sub with and into the Company. Pursuant to the Merger, the Company will become a wholly owned subsidiary of the Parent, and each outstanding share of common stock, par value $1.00 per share, of the Company (the “Company Common Stock”), other than shares held in treasury and shares held by Parent or Merger Sub, in each case not held on behalf of third parties, will be converted into the right to receive 0.2550 shares of common stock, par value $0.01 per share, of the Parent (the “Parent Common Stock”) (the “Consideration”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Consideration to be received by the holders of shares of the Company Common Stock pursuant to the Merger Agreement is fair, from a financial point of view, to the holders of shares of the Company Common Stock (other than Parent, Merger Sub and their respective affiliates).

For purposes of the opinion set forth herein, we have:

1)

Reviewed certain publicly available financial statements and other business and financial information of the Company and the Parent, respectively;

2)

Reviewed certain internal financial statements and other financial and operating data concerning the Company;

3)

Reviewed certain financial projections with respect to the Company prepared by the management of the Company and certain financial projections with respect to the Company that were derived from a consensus of selected Wall Street equity research financial forecasts (the “Street Projections”);

4)

Discussed the past and current operations and financial condition and the prospects of the Company, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, with senior executives of the Company;

5)

Reviewed the pro forma impact of the Merger on the Parent’s cash flow, consolidated capitalization and certain financial ratios;

6)

Discussed the current operations and financial condition and certain prospects of Parent with senior executives of Parent;

7)

Reviewed the reported prices and trading activity for the Company Common Stock and the Parent Common Stock;

8)

Compared the financial performance of the Company and the prices and trading activity of the Company Common Stock with that of certain other publicly-traded companies comparable with the Company and its securities;

9)

Reviewed the financial terms, to the extent publicly available, of certain comparable acquisition transactions;

B-1

10)

Participated in certain discussions among representatives of the Company and their legal advisors;

11)

Reviewed the Merger Agreement and certain related documents; and

12)

Performed such other analyses and reviewed such other information and considered such other factors as we have deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to us by the Company, and formed a substantial basis for this opinion. With respect to the financial projections prepared by management of the Company, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company of the future financial performance of the Company. With respect to the Street Projections, at your direction, we have assumed that they are reasonable bases upon which to evaluate the business and financial prospects of the Company. We express no view as to the financial projections prepared by the management of the Company or the Street Projections or the assumptions on which they were based. In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the Merger will be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended, and that the definitive Merger Agreement will not differ in any material respect from the draft thereof furnished to us. Morgan Stanley has assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed Merger, no delays, limitations, divestitures, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed Merger. We are not legal, tax, or regulatory advisors. We are financial advisors only and have relied upon, without independent verification, the assessment of the Parent and the Company and their legal, tax, or regulatory advisors with respect to legal, tax, or regulatory matters.
