Form of 2023 Omnibus Incentive Plan Performance Share Agreement

The Participant set forth on Appendix A has been granted an Award (the “Award”) of Restricted Stock Units (“PSUs”) pursuant to the Murphy USA Inc. 2023 Omnibus Incentive Plan (as it may be amended from time to time, the “Plan”), and this PSU Agreement (this “Agreement”), dated as indicated in Appendix A (the “Grant Date”). Except as otherwise indicated, any capitalized term used but not defined herein shall have the meaning set forth in the Plan.

1.Issuance of Shares. Each PSU shall represent the right to receive one Share upon the vesting of such PSU, as determined in accordance with and subject to the terms of this Agreement and the Plan. The target number of PSUs is set forth in Appendix A.

2.Vesting. Subject to Section 3 and 4, the Award shall vest in accordance with the terms and conditions set forth in Appendix A.

3.Termination of Service.

(a)Termination Due to Death or Disability. In the event of the Participant’s Termination of Service due to the Participant’s death or Disability, a prorated number of the PSUs will be eligible to vest on the Vesting Date (as defined in Appendix A) in an amount equal to the product of (i) the total number of PSUs granted pursuant to this Award multiplied by (ii) a fraction, (A) the numerator of which is the number of full calendar months elapsed between the Grant Date through the date of the Participant’s Termination of Service (not to exceed 36 months) and (B) the denominator of which is 36, subject to actual achievement of the Performance Metrics (as defined in Appendix A) as of the end of the Performance Period (as defined in Appendix A).

(b)Retirement. Notwithstanding anything to the contrary herein, in the event of the Participant’s Termination of Service for any reason other than due to a Termination of Service for Cause (or the Participant’s voluntary resignation at a time when grounds for a Termination of Service for Cause exist) at a time when the Participant is Retirement Eligible, then a prorated number of the PSUs will be eligible to vest on the Vesting Date in an amount equal to the product of (i) the total number of PSUs granted pursuant to this Award multiplied by (ii) a fraction, (A) the numerator of which is the number of full calendar months elapsed between the Grant Date through the date of the Participant’s Termination of Service and (B) the denominator of which is 36, subject to actual achievement of the Performance Metrics as of the end of the Performance Period. For purposes of this Agreement, “Retirement Eligible” means (x) the Participant has attained age 65 or (y) the Participant has attained age 55 and the Participant’s length of employment with the Company and its Subsidiaries (including, for these purposes, employment with the Company’s predecessor, Murphy Oil Corporation, a Delaware corporation, and any of its Subsidiaries prior to September 1, 2013) is at least 10 years.

(c)All Other Terminations. In the event of the Participant’s Termination of Service by the Company in any circumstances other than those described in Sections 3(a) and (b), any PSUs that are not vested as of the date of such Termination of Service will be immediately forfeited and cancelled as of the date of such Termination of Service.

4.Change in Control. In the event of a Change in Control, the Committee, in its sole discretion, may take the actions contemplated by Section 12(c) of the Plan with respect to

the PSUs, including providing for (a) the continuation or assumption of the PSUs by the Company (if it is the surviving entity) or by the successor or surviving entity (or its parent), in which case the PSUs will continue to be subject to the terms of this Award Agreement (including this Section 4), or (b) the vesting of the PSUs immediately prior to such Change in Control in the event the buyer or the successor or surviving entity (or its parent) fails to continue or assume the PSUs; provided, however, in each case, the Performance Metrics shall be deemed to have been achieved at the greater of (x) the actual achievement of the performance metrics, to the extent determinable, for the period (A) commencing on the first day of the Performance Period and (B) ending on the date immediately prior to such Change in Control and (y) 100%. If, in connection with the Change in Control, the PSUs are assumed or continued pursuant to clause (a) above, then, in the event of the Participant’s Termination of Service (i) due to the Participant’s death or Disability or (ii) by the Company (or, as applicable, the successor or the surviving entity (or its parent)) without Cause, in each case on or within 24 months following such Change in Control, the PSUs will become immediately vested as of the date of such Termination of Service. Following a Change in Control in which the PSUs are continued or assumed pursuant to clause (a) above, such PSUs may be settled in cash, shares or a combination thereof.

5.Voting Rights. The Participant shall have no voting rights or any other rights as a shareholder of the Company with respect to the PSUs unless and until the Participant becomes the record owner of the Shares underlying the PSUs.

6.Transferability of PSUs. Except as may be permitted by the Committee, neither the PSUs nor any rights of the Participant with respect thereto shall be assignable, alienable, saleable or transferable by the Participant other than (a) by will or pursuant to the laws of descent and distribution or (b) by order of any court of competent jurisdiction, including with respect to any domestic relations order or divorce decree. Any attempts to assign, alienate, sell or otherwise transfer the RSUs (or any the Participant’s rights with respect thereto) shall be void and the Participant’s rights to the RSUs shall therefore be forfeited.

7.Dividend Equivalents. Unless otherwise determined by the Committee, if a dividend or other distribution is paid on Shares during the period commencing on the Grant Date and ending on the date on which the Shares underlying the PSUs earned are distributed to the Participant pursuant to this Agreement, the Participant shall receive a number of dividend equivalents to be denominated and paid, subject to Section 15(h) of the Plan, in a number of Shares (“Dividend Shares”) with a value equal to the amount of the dividends or other distribution that the Participant would have received had the Shares underlying the Target PSUs (as defined in Appendix A) has been distributed to the Participant, which such number of Dividend Shares shall be determined based on the Fair Market Value of the Shares on the record date for such dividend or other distribution. Any such Dividend Shares shall be subject to the applicable Performance Metrics as if granted as part of the Target PSUs and shall be earned and paid to the Participant at the same time as, and shall be subject to the same vesting and forfeiture provisions (including the performance metrics) as set forth in this Agreement with respect to, the PSUs. For the avoidance of doubt, no Dividend Shares will be paid to the Participant with respect to any unearned, canceled or forfeited PSUs.

8.Distribution of Shares. Subject to the provisions of this Agreement, upon the vesting of any of the PSUs, the Company shall deliver to the Participant, as soon as reasonably practicable (and in no event later than 60 days) after the applicable vesting date, one Share for each such PSU and each Dividend Share (as applicable). Upon the delivery of Shares, such Shares shall be fully assignable, alienable, saleable and transferrable by the Participant; provided that any such assignment, alienation, sale, transfer or other alienation with respect to such Shares shall be in accordance with applicable securities laws and any applicable Company policy.

9.Responsibility for Taxes.

(a)The Participant acknowledges that, regardless of any action taken by the Company, the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable to the Participant (“Tax-Related Items”) is and remains the Participant’s responsibility and may exceed the amount actually withheld by the Company. The Participant further acknowledges that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Award, including, but not limited to, the grant, vesting or settlement of the Award, the subsequent sale of Shares acquired upon settlement of the Award and the receipt of any dividends, dividend equivalents and/or Dividend Shares; and (ii) does not commit to and is under no obligation to structure the terms of the grant or any aspect of the Award to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction, the Participant acknowledges that the Company may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b)Upon the vesting and/or settlement of the PSUs (or as of the date of any relevant taxable or tax withholding date or other date on which the value of any PSUs or the Dividend Shares otherwise become includible in the Participant’s gross income for tax purposes) (the “Tax Withholding Date”), the Participant shall be required to pay to the Company, and the Company shall have the right to deduct from any compensation payable to the Participant, the amount of any applicable federal, state, local and foreign Tax-Related Items that the Company determines must be withheld with respect to the Award (the “Tax Withholding Obligations”). In this regard, unless otherwise determined by the Committee, the Tax Withholding Obligations shall be satisfied by the Company withholding, in accordance with Section 16(e) of the Plan, from the number of Shares (including the Dividend Shares) otherwise issuable upon settlement of the PSUs, a portion of such Shares (including Dividend Shares) having an aggregate Fair Market Value equal to the amount of the applicable Tax Withholding Obligations. Notwithstanding the foregoing, the Participant agrees and authorizes the Company, or its respective agents, to satisfy any applicable Tax Withholding Obligations in respect of the Award by any of the following means, as may be determined by the Committee (or its delegate) in its discretion from time to time: (i) withholding from the Participant’s wages or other cash compensation paid to the Participant by the Company; (ii) requiring the Participant to remit the aggregate amount of such Tax Withholding Obligations to the Company in full, in cash or by check, bank draft or money order payable to the order of the Company; (iii) through a procedure whereby the Participant delivers irrevocable instructions to a broker designated by the Committee to sell Shares obtained upon settlement of the Award and to deliver promptly to the Company an amount of the proceeds of such sale equal to the amount of the Tax-Related Items (“sell-to-cover”); (iv) by a “net settlement” procedure under which the Company reduces the number of Shares issued on settlement of the Award by the number of Shares with an aggregate fair market value that equals the amount of the Tax Withholding Obligations; or (v) any other method of withholding determined by the Committee and permitted by applicable law.

(c)The Participant agrees to pay to the Company any amount of Tax-Related Items that the Company may be required to withhold or account for as a result of the Participant’s participation in the Plan that cannot be satisfied by the means described in Section 9(b). The Company may refuse to issue or deliver the Shares or the proceeds of

the sale of Shares, if the Participant fails to comply with the Participant’s obligations in connection with the Tax-Related Items.

10.Cancellation/Clawback. The Participant hereby acknowledges and agrees that the Participant and the Award are subject to the terms and conditions of Section 18 (Cancellation or “Clawback” of Awards) of the Plan.
