Section 6.    Payment of Awards. As soon as practicable after the Committee has received the appropriate financial and other data after the end of a Plan Year, the Committee will for each Participant certify in writing the extent to which the applicable Performance Goals for such Participant have been met and the corresponding amount of the Award earned by such Participant.

(b)Termination for Reasons Other than Death, Disability, or Retirement. In the event a Participant’s employment is terminated with the Company and all Subsidiaries prior to the end of the Performance Period for any reason other than death, Disability, or Retirement, including termination by the Company with or without Cause or the Participant’s resignation for any reason, or a Participant is in the employ of a Subsidiary and the Subsidiary ceases to be a Subsidiary of the Company (unless the Participant continues in the employ of the Company or another Subsidiary), the Participant’s Award for such Performance Period shall be immediately forfeited and the Participant shall have no right to any payment thereafter; provided, however, that under such circumstances, except in the event of the termination of the Participant’s employment by the Company for Cause, the Committee may, in its sole discretion, pay the Participant an amount not to exceed a percentage of the amount earned according to the terms of the Award equal to the portion of the Performance Period through the Participant’s termination.

(c)Termination for Cause. In the event a Participant’s employment is terminated by the Company for Cause prior to the Payment Date for an Award, the Participant shall immediately forfeit and shall have no right to any payment thereafter with respect to such Award.

Section 8.    Payment of Withholding Taxes and Other Amounts.

Section 9.    Plan Amendment, Modification, and Termination. Subject to applicable law, the Committee may amend, suspend or terminate the Plan, any Award or any respective portion thereof at any time as the Committee may deem to be in the best interests of the Company, including to reduce or eliminate the compensation or other economic benefit otherwise due pursuant to an Award.

Section 10. Non-Funded, Unsecured Obligation. A Participant’s only interest under the Plan shall be the right to receive a cash payment under an Award pursuant to the terms of the Award and the Plan (subject to the authority of the Committee pursuant to Section 3, Section 6, Section 7, Section 8 and Section 9 of the Plan). No portion of the amount payable to Participants under the Plan shall be held by the Company or any Subsidiary in trust or escrow or any other form of asset segregation. To the extent that a Participant acquires a right to receive such a cash payment under the Plan, such right shall be no greater than the right of any unsecured, general creditor of the Company.

Section 11. Term and Duration of the Plan. The Plan was originally effective as of January 1, 2019; amended and restated (effective January 1, 2024) upon its adoption by the Board; and subsequently amended and restated (effective August 14, 2024) as set forth herein upon its adoption by the Committee on August 14, 2024. The Plan, as amended and restated (effective August 14, 2024) as set forth herein, shall apply for purposes of the Plan Year which commenced on January 1, 2024 and for each subsequent Plan Year (subject to Section 9), and will remain in effect until such time as the Plan is terminated by the Committee. Any payments pursuant to Awards outstanding upon termination of the Plan may continue to be made in accordance with the terms of the Awards, subject to the authority of the Committee pursuant to Section 3 and Section 9 of the Plan.

Section 12. Section 409A of the Code. With respect to Awards subject to Section 409A of the Code, the Plan is intended to comply with the requirements of Section 409A of the Code, and the provisions of the Plan and any Award shall be interpreted in a manner that satisfies the requirements of Section 409A of the Code, and the Plan shall be operated accordingly. If any provision of the Plan or any term or condition of any Award would otherwise frustrate or conflict with this intent, the provision, term or condition shall be interpreted and deemed amended so as to avoid this conflict. Notwithstanding anything in the Plan to the contrary, if the Board considers a Participant to be a “specified employee” under Section 409A of the Code at the time of such Participant’s “separation from service” (as defined in Section 409A of the Code), and any amount hereunder is “deferred compensation” subject to Section 409A of the Code, any distribution of such amount that otherwise would be made to such Participant with respect to an Award as a result of such “separation from service” shall not be made until the date that is six months after such “separation from service,” except to the extent that earlier distribution would not result in such Participant’s incurring interest or additional tax under Section 409A of the Code. If an Award includes a “series of installment payments” (within the meaning of Section 1.409A-2(b)(2)(iii) of the Treasury Regulations), the Participant’s right to such series of installment

payments shall be treated as a right to a series of separate payments and not as a right to a single payment. Notwithstanding the foregoing, the tax treatment of the benefits provided under the Plan or any Award is not warranted or guaranteed, and in no event shall the Company be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by any Participant on account of non- compliance with Section 409A of the Code.

Section 13. Miscellaneous.

(a)Employment. Nothing in the Plan will interfere with or limit in any way the right of the Company or any Subsidiary to terminate the employment or otherwise modify the terms and conditions of the employment of any Key Employee or Participant at any time, nor confer upon any Key Employee or Participant any right to continue in the employ of the Company or any Subsidiary.

(b)Restrictions or Transfer. Except pursuant to testamentary will or the laws of descent and as otherwise expressly permitted by the Plan, no right or interest of any Participant in an Award will be assignable or transferable, or subjected to any lien, during the lifetime of the Participant, either voluntarily or involuntarily, directly or indirectly, by operation of law or otherwise.

(c)Governing Law. The validity, construction, interpretation, administration, and effect of the Plan and any rules, regulations, and actions relating to the Plan will be governed by and construed exclusively in accordance with the internal, substantive laws of the State of Delaware, without regard to the conflict of law rules of the State of Delaware or any other jurisdiction.

(d)Successors. The Plan will be binding upon and inure to the benefit of the successors of the Company and the Participants.

Section 14. Clawback. A Participant whose negligent, intentional, or gross misconduct contributes to the Company’s having to restate all or a portion of its financial statements shall immediately forfeit any portion of an Award earned in the period covered by such financial statements that would not have otherwise been earned under such restated financial statements, as determined in each case, by the Committee in good faith. The Committee shall have full authority to implement any policies and procedures necessary to comply with Section 10D of the Exchange Act and any rules promulgated thereunder and any other regulatory regimes. Notwithstanding anything to the contrary contained herein, any Awards granted under the Plan (including any amounts or benefits arising from such Awards) shall be subject to any clawback or recoupment arrangements or policies the Company has in place from time to time (including the Murphy USA Inc. Supplemental Compensation Recoupment Policy, the Murphy USA Inc. Financial Restatement Compensation Recoupment Policy and any other such policy adopted to comply with Rule 10D-1 of the Exchange Act and any related listing rules or regulations, including Section 303A.14 of the NYSE Listed Company Manual), and the Committee may, to the extent permitted, and shall, to the extent required, by applicable law, stock exchange rules or Company policy or arrangement, cancel or require forfeiture or reimbursement of any Awards granted to the Participant (and any benefits derived therefrom).
