Item 1.01. Entry into a Material Definitive Agreement.

On May 28, 2024, Marathon Oil Corporation, a Delaware corporation (“Marathon”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ConocoPhillips, a Delaware corporation (“ConocoPhillips”), and Puma Merger Sub Corp., a wholly owned subsidiary of ConocoPhillips (“Merger Sub”).

The Merger Agreement provides that, among other things and subject to the terms and conditions of the Merger Agreement, (1) Merger Sub will be merged with and into Marathon (the “Merger”), with Marathon surviving and continuing as the surviving corporation in the Merger, and (2) at the effective time of the Merger (the “Effective Time”), each outstanding share of common stock of Marathon (other than certain Excluded Shares and Converted Shares (each as defined in the Merger Agreement)) will be converted into the right to receive 0.2550 (the “Exchange Ratio”) shares of common stock of ConocoPhillips (the “Merger Consideration”).

The Merger Agreement also specifies the treatment of outstanding Marathon equity awards in connection with the Merger, which shall be treated as follows at the Effective Time:

• Each outstanding restricted stock unit award of Marathon that vests solely based on service (other than any granted to a non-employee director) will be canceled and converted into a restricted stock unit award of ConocoPhillips in respect of a number of shares of ConocoPhillips common stock (rounded to the nearest whole share) equal to the product of (i) the total number of shares of Marathon common stock subject to such award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio.

• Each outstanding restricted stock unit award or deferred stock unit award granted to a non-employee director of Marathon that is outstanding immediately prior to the Effective Time will immediately vest with respect to 100% of the shares of Marathon common stock subject to such award and such shares of Marathon common stock will be converted into the right to receive the Merger Consideration and an amount in cash equal to any accrued but unpaid dividend equivalents.

• Each outstanding and vested stock option to purchase shares of Marathon common stock 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 of the applicable option award multiplied by (B) the number of shares of Marathon common stock subject to such option award immediately prior to the Effective Time, divided by (ii) the Parent Closing Price (defined as the volume-weighted average price of the ConocoPhillips common stock for the five consecutive trading days ending two trading days prior to the closing date); provided, that any option award that has an exercise price per share of Marathon common stock 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 Parent Closing Price.

• Each outstanding performance unit award of Marathon will immediately vest and be converted into the right to receive (i) in the case of 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 common stock subject to such performance unit award immediately prior to the Effective Time reflecting the attainment of the applicable performance metrics at the maximum level of performance multiplied by (y) the Exchange Ratio and (B) an amount in cash equal to any accrued but unpaid dividend equivalents, or (ii) in the case of 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 multiplied by the average of the daily closing price of a share of Marathon 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 Marathon common stock that is greater than the Average Price then such higher price will be used for such portion of the award, plus any dividend equivalents accrued with respect to such performance unit awards, in the cases of each of clauses (i) and (ii), as promptly as administrative possible after closing, but in no event later than ten business days after the closing.

The board of directors of Marathon has unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are fair to, and in the best interests of, Marathon and the holders of Marathon’s common stock, (2) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the Merger, and (3) resolved to recommend that the Marathon stockholders approve and adopt the Merger Agreement and the transactions contemplated thereby, including the Merger.

The completion of the Merger is subject to satisfaction or waiver of certain customary mutual closing conditions, including (1) the receipt of the required approvals from Marathon stockholders, (2) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (3) certain other specified regulatory approvals having been obtained, (4) the absence of any governmental order or law that makes consummation of the Merger illegal or otherwise prohibited, (5) the effectiveness of the registration statement on Form S-4 to be filed by ConocoPhillips pursuant to which the shares of ConocoPhillips common stock to be issued in connection with the Merger are registered with the Securities and Exchange Commission (the “SEC”), and (6) the authorization for listing of ConocoPhillips common stock to be issued in connection with the Merger on the NYSE. The obligation of each party to consummate the Merger is also conditioned upon (1) the other party’s representations and warranties being true and correct (subject to certain materiality exceptions), (2) the other party having performed in all material respects its obligations under the Merger Agreement, (3) the absence of a material adverse effect on the other party and (4) the receipt of an officer’s certificate from the other party to such effect.

The Merger Agreement contains customary representations and warranties of Marathon and ConocoPhillips relating to their respective businesses, financial statements and public filings, in each case generally subject to customary materiality qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of Marathon and ConocoPhillips, including, subject to certain exceptions, covenants relating to conducting their respective businesses in the ordinary course consistent with past practice, and to refrain from taking certain actions without the other party’s consent. Marathon and ConocoPhillips also agreed to use their respective reasonable best efforts to cause the Merger to be consummated and to obtain expiration or termination of the waiting period under the HSR Act and to obtain other specified regulatory approvals, subject to certain limitations set forth in the Merger Agreement.

The Merger Agreement provides that, during the period from the date of the Merger Agreement until the Effective Time, Marathon will be subject to certain restrictions on its ability to solicit alternative competing proposals from third parties, to provide non-public information to third parties and to engage in discussions with third parties regarding alternative competing proposals, subject to customary exceptions. Marathon is required to call a meeting of its stockholders to approve the Merger Agreement and, subject to certain exceptions, to recommend that its stockholders approve the Merger Agreement.

The Merger Agreement contains customary termination rights for each of Marathon and ConocoPhillips, including, among others, if the consummation of the Merger does not occur on or before May 28, 2025 (subject to two potential extensions to November 28, 2025 and May 28, 2026 if the required regulatory approvals have not been received but all other conditions to closing have been satisfied or waived (except for those conditions that by their nature are to be satisfied at closing)) (such date, the “end date”). Additionally, the Merger Agreement permits Marathon, subject to compliance with certain requirements and payment of a termination fee (described below), to terminate the Merger Agreement to enter into a definitive agreement for a superior alternative competing proposal than the Merger.

Upon termination of the Merger Agreement under specified circumstances, including the (1) termination by Marathon to enter into a definitive agreement for a superior alternative competing proposal than the Merger, (2) termination by ConocoPhillips in the event of a change of recommendation by the Marathon board of directors or (3) termination by ConocoPhillips because Marathon, its subsidiaries or any of its directors or executive officers materially breached its non-solicitation obligations, Marathon would be required to pay ConocoPhillips a termination fee of $557,000,000. In addition, (i) upon termination of the Merger Agreement (a) by either ConocoPhillips or Marathon in connection with a failure of Marathon’s stockholders to approve the Merger and if a Company Competing Proposal (as defined in the Merger Agreement) was publicly announced and not publicly

withdrawn at least seven business days prior to the Marathon stockholder meeting or (b) (x) by ConocoPhillips in connection with a breach by Marathon of its representations, warranties and covenants (other than the non-solicitation covenant) that results in the failure of the applicable closing conditions relating thereto or (y) by either ConocoPhillips or Marathon in connection with a failure to close the Merger by the end date and, in the case of (x) and (y), if prior to such termination a Company Competing Proposal (as defined in the Merger Agreement) was announced or communicated to the Marathon board of directors and not withdrawn at least seven business days prior to termination and (ii) if Marathon enters into a definitive agreement in respect of or consummates a Company Competing Proposal within twelve months of such termination described in clause (i), then Marathon would be required to pay ConocoPhillips a termination fee of $557,000,000. Moreover, if the Merger Agreement is terminated because of a failure of Marathon’s stockholders to approve the Merger, Marathon will be required to pay ConocoPhillips $86,000,000. In no event will ConocoPhillips be entitled to receive more than one termination fee, net of any expense reimbursement.

The foregoing description of the Merger Agreement and the transactions contemplated thereby in this Current Report on Form 8-K is only a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto and incorporated by reference herein.

The Merger Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about Marathon. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement as of the specific dates therein, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Marathon’s public disclosures.

Forward-Looking Statements

This communication includes “forward-looking statements” as defined under the federal securities laws. All statements other than statements of historical fact included or incorporated by reference in this communication, including, among other things, statements regarding the proposed business combination transaction between ConocoPhillips (“ConocoPhillips”) and Marathon Oil Corporation (“Marathon”), future events, plans and anticipated results of operations, business strategies, the anticipated benefits of the proposed transaction, the anticipated impact of the proposed transaction on the combined company’s business and future financial and operating results, the expected amount and timing of synergies from the proposed transaction, the anticipated closing date for the proposed transaction and other aspects of ConocoPhillips’ or Marathon’s operations or operating results are forward-looking statements. Words and phrases such as “ambition,” “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “will,” “would,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and other similar words can be used to identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. Where, in any forward-looking statement, ConocoPhillips or Marathon 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 ConocoPhillips’ or Marathon’s control. Therefore, actual outcomes and results may differ materially from what is expressed or forecast in the forward-looking statements.

The following important factors and uncertainties, among others, could cause actual results or events to differ materially from those described in forward-looking statements: ConocoPhillips’ ability to successfully integrate Marathon’s businesses and technologies, which may result in the combined company not operating as effectively and efficiently as expected; the risk that the expected benefits and synergies of the proposed transaction may not be fully achieved in a timely manner, or at all; the risk that ConocoPhillips or Marathon will be unable to retain and hire key personnel and maintain relationships with their suppliers and customers; the risk associated with Marathon’s ability to obtain the approval of its stockholders required to consummate the proposed transaction and the timing of the closing of the proposed transaction, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all or the failure of the transaction to close for any other reason or to close on the anticipated terms, including the anticipated tax treatment; the risk that any regulatory approval, consent or authorization that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; the occurrence of any event, change or other circumstance that could give rise to the termination of the proposed transaction; unanticipated difficulties, liabilities or expenditures relating to the transaction; the effect of the announcement, pendency or completion of the proposed transaction on the parties’ business relationships and business operations generally; the effect of the announcement or pendency of the proposed transaction on the parties’ common stock prices and uncertainty as to the long-term value of ConocoPhillips’ or Marathon’s common stock; risks that the proposed transaction disrupts current plans and operations of ConocoPhillips or Marathon and their respective management teams and potential difficulties in hiring or retaining employees as a result of the proposed transaction; and other economic, business, competitive and/or regulatory factors affecting ConocoPhillips’ or Marathon’s businesses generally as set forth in their filings with the Securities and Exchange Commission (the “SEC”). The registration statement on Form S-4 and proxy statement/prospectus that will be filed with the SEC will describe additional risks in connection with the proposed transaction. While the list of factors presented here is, and the list of factors to be presented in the registration statement on Form S-4 and proxy statement/prospectus are considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. For additional information about other factors that could cause actual results to differ materially from those described in the forward-looking statements, please refer to ConocoPhillips’ and Marathon’s respective periodic reports and other filings with the SEC, including the risk factors contained in ConocoPhillips’ and Marathon’s most recent Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. Forward-looking statements represent current expectations and are inherently uncertain and are made only as of the date hereof (or, if applicable, the dates indicated in such statement). Except as required by law, neither ConocoPhillips nor Marathon undertakes or assumes any obligation to update any forward-looking statements, whether as a result of new information or to reflect subsequent events or circumstances or otherwise.
