This Performance Share Unit Agreement (the “Agreement”) is made and entered into by and between HF Sinclair Corporation, a Delaware corporation (the “Company”), and you. This Agreement is entered into as of the ____ day of ____________, 2023 (the “Date of Grant”).

WHEREAS, the Company, as part of your compensation for services provided to the Company or any of its subsidiaries and in order to further induce you to materially contribute to the success of the Company, agrees to grant you this performance share unit award;

WHEREAS, the Company adopted the Plan (as defined in Appendix A) under which the Company is authorized to grant stock units and phantom stock awards, as applicable to certain employees, directors and other service providers of the Company and its subsidiaries;

WHEREAS, a copy of the Plan has been furnished to you and shall be deemed a part of this Agreement as if fully set forth herein and the terms capitalized but not defined herein or on Appendix A attached hereto shall have the meanings set forth in the Plan; and

WHEREAS, you desire to accept the performance share unit award made pursuant to this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants set forth herein and for other valuable consideration hereinafter set forth, the parties hereto agree as follows:

1.Grant. Subject to the conditions set forth below, the Company hereby grants you effective as of the Date of Grant, as a matter of separate inducement but not in lieu of any cash or other compensation for your services for the Company (or any of its subsidiaries), an award (the “Award”) of ____ shares of Phantom Stock consisting of performance share units (the “Performance Share Units”) plus the additional rights to receive possible dividend equivalents, in accordance with the terms and conditions set forth herein. Depending on the Company’s performance, you may earn from zero percent (0%) to two hundred percent (200%) of the Performance Share Units, based on the Company’s performance on two measures set forth in Section 4 over a designated performance period compared to the performance of a group of peer companies selected by the Committee.

2.No Shareholder Rights. The Performance Share Units granted pursuant to this Agreement do not, and shall not, entitle you to any rights as a holder of Stock, including the right to vote, prior to the date Stock is issued to you in settlement of the Award.

3.Dividend Equivalents. In the event that the Company declares and pays a dividend in respect of its outstanding Stock on or after the Date of Grant and, on the record date for such dividend, you hold Performance Share Units granted pursuant to this Agreement that have not been settled, the Company shall pay to you an amount in cash equal to the cash dividends you would have received if you were the holder of record of the number of shares of Stock related to the Target Number (as defined in Appendix A) of your Performance Share Units on such record date. Such payment (the “Dividend Equivalents”) shall be made on or promptly following the date that the Company pays such dividend (however, in no event shall the Dividend Equivalents be paid later than 30 days following the date on which the Company pays such dividend to its shareholders generally). Your rights with respect to the Performance Share Units shall remain

forfeitable at all times prior to the date on which the rights become earned and settled as set forth in Section 9, as adjusted by Section 7, as applicable.

4.Performance Period and Measures. This Section 3 sets forth the details of the Performance Award for the “Performance Period,” which begins on October 1 of the calendar year of the Date of Grant (“Year One”) and ends on September 30 of the third calendar year following Year One (“Year Three”). If you are employed by the Company or any of its subsidiaries on December 1 of Year Three (the last day of the Service Period) you will be entitled to a payment in shares of Stock in the amount determined under Section 4(b) or pursuant to Section 7, as applicable, and payable at the time indicated in this Section 9.

(a)Performance Measures. The number of Performance Share Units earned for the Performance Period is determined by comparing the Company’s performance on the two measures listed below over the Performance Period to the performance of the Peer Group over the Performance Period on the same two measures. The two performance measures are Return on Capital Employed and Total Shareholder Return.

(b)Shares Payable. The number of shares of Stock payable is equal to the result of multiplying the total number of Performance Share Units awarded by the Performance Unit Payout Percentage (“Earned PSUs”) or as otherwise specified in the Agreement.

5.Restrictions; Forfeiture. The Performance Share Units are restricted in that they cannot be sold, transferred or otherwise alienated or hypothecated until Stock related to such Performance Share Units is issued pursuant to Section 9 following the removal or expiration of the restrictions as contemplated in Section 6 (and Section 7, if applicable) of this Agreement. In the event you cease to be an employee of the Company or any of its subsidiaries, other than as provided in Section 7 below, or in the event that you violate the covenants set forth in Section 24 of this Agreement, the Performance Share Units that are not vested on the date of your termination of employment shall be immediately forfeited.

6.Expiration of Restrictions and Risk of Forfeiture. The restrictions on the Performance Share Units granted pursuant to this Agreement will expire and will become nonforfeitable as set forth in Section 4 and this Agreement, provided that you remain an employee of the Company or any of its subsidiaries until the applicable dates and times set forth therein. Performance Share Units that have become vested and non-forfeitable as provided in this Agreement are referred to herein as “Vested.”

7.Termination of Employment.

(a)Termination Generally. Subject to subsections (b), (c), and (d) below, if your employment relationship with the Company or any of its subsidiaries is terminated prior to the last day of the Service Period for any reason (including if you voluntarily separate from employment (other than due to your Retirement) or are terminated by action of the Company (including termination for Cause but other than a Special Involuntary Termination)) such that, as a result of such termination you are no longer employed by the Company or any of its subsidiaries, then those Performance Share Units that have not become Vested as of the date of your termination of employment shall become null and void and those Performance Share Units shall be forfeited to the Company, for no consideration, immediately following your termination of employment. The Performance Share Units that are Vested as of the date of your termination of employment shall not be forfeited to the Company and will be settled in accordance with Section 9.

(b)Death, Disability or Retirement. In the event of your termination of employment prior to the last day of the Service Period due to your (i) death, (ii) total and

permanent disability, as determined by the Committee in its sole discretion, or (iii) Retirement, in each case, before all the Performance Share Units granted pursuant to this Agreement have become Vested, you will forfeit immediately following your termination of employment, a number of Performance Share Units equal to the number of Performance Share Units specified in this Agreement times the percentage that (A) the number of days beginning on the day on which the termination due to death, disability or Retirement occurs and ending on the last day of the Service Period, (B) bears to the total number of days in the Service Period, and any remaining Performance Share Units that are not vested will become Vested immediately following your termination of employment assuming a Performance Unit Payout Percentage of one hundred percent (100%) instead of the Performance Unit Payout Percentage that would otherwise be determined at end of the Performance Period in accordance with Section 4; provided, however, that any fractional Performance Share Units will become null and void and automatically forfeited. In its sole discretion, the Committee may decide to vest all of the Award in lieu of the prorated portion of the Award as provided in this Section 7(b).

(c)Special Involuntary Termination. In the event of a Special Involuntary Termination prior to the last day of the Service Period, the Target Number (as defined in Appendix A) of Performance Share Units granted pursuant to this Agreement will become Vested immediately following such Special Involuntary Termination. Payment pursuant to this Section 7(c) is in lieu of payment pursuant to Section 7(a) and if you receive payment pursuant to this Section 7(c) you will not be entitled to any payment pursuant to Section 7(b).

(d)Effect of Employment Agreement. Notwithstanding any provision herein to the contrary, in the event of any inconsistency between this Section 7 and any written employment, change in control, or similar agreement entered into by and between you and the Company (or any of its subsidiaries), the terms of the employment, change in control or similar agreement shall control, subject to compliance with Section 409A of the Code.

(e)Date of Termination. For purposes of this Agreement, your employment will be deemed to terminate on the date that you cease to be actively employed by the Company (or any subsidiary) and shall not be extended by any notice period mandated or implied under local law during or for which you receive pay in lieu of notice or severance pay. For the avoidance of doubt, changes in your employment by and between the Company and any subsidiary of the Company shall not be treated as a termination of employment. The Company shall have the sole discretion to determine when you are no longer actively employed for purposes of this Agreement, without reference to any other agreement, written or oral, including your contract of employment.

8.Leave of Absence. With respect to the Performance Share Units, the Company may, in its sole discretion, determine that if you are on a leave of absence for any reason you will be considered to still be in the employ of, or providing services to, the Company (or a subsidiary), provided that, subject to applicable law, your rights to the Performance Share Units, if any, during a Performance Period in which such a leave of absence occurs will be prorated to reflect the period of time during the Performance Period that you provided actual services to the Company.

9.Settlement. Stock shall be issued to you in settlement of your Vested Performance Share Units by March 15th of the year following the date upon which your Performance Share Units vest; provided, however, if any Performance Share Units is or becomes subject to Section 409A of the Code, settlement of such Performance Share Units shall be on or before December 31st, or (if later) 90 days, following, the date upon which such Performance Share Units becomes Vested. At the time of settlement, the Company shall cause to be issued Stock registered in your name in payment of the Award. The Company shall evidence the Stock to be issued in payment of the Performance Share Units in the manner it deems appropriate. The value of any fractional

Performance Share Units shall be rounded down at the time Stock is issued to you. No fractional shares, nor the cash value of any fractional shares, will be issuable or payable to you pursuant to this Agreement. The Committee’s determination of the amount payable shall be binding upon you and your beneficiary or estate. The value of Stock shall not bear any interest owing to the passage of time. Neither this Section 9 nor any action taken pursuant to or in accordance with this Section 9 shall be construed to create a trust or a funded or secured obligation of any kind.

10.Adjustment in Number of Performance Share Units. The number of Performance Share Units subject to this Agreement shall be adjusted to reflect stock splits or other changes in the capital structure of the Company, all in accordance with the Plan. In the event that the outstanding Stock of the Company is exchanged for a different number or kind of shares or other securities, or if additional, new or different shares are distributed with respect to the Stock through merger, consolidation, or sale of all or substantially all of the assets of the Company, there shall be substituted for the Stock under the Performance Share Units subject to this Agreement the appropriate number and kind of shares of new or replacement securities as determined in the sole discretion of the Committee, subject to the terms and provisions of the Plan.

11.Payment of Taxes. The Company may require you to pay to the Company (or the Company’s subsidiary if you are an employee of a subsidiary of the Company), an amount the Company deems necessary to satisfy its (or its subsidiary’s) current or future withholding with respect to federal, state or local income or other taxes that you incur as a result of the Award. With respect to any tax withholding (and to the extent permissible pursuant to Rule 16b-3 under the Exchange Act, if applicable), you may (a) direct the Company to withhold from the Stock to be issued to you under this Agreement the number of shares of Stock necessary to satisfy the Company’s withholding of such taxes, which determination will be based on the Stock’s Fair Market Value at the time such determination is made; (b) deliver to the Company Stock sufficient to satisfy the Company’s tax withholding, based on the Stock’s Fair Market Value at the time such determination is made; or (c) deliver cash to the Company sufficient to satisfy its tax withholding obligations. If you desire to elect to use the stock withholding option described in subparagraph (a), you must make the election at the time and in the manner the Company prescribes and the maximum number of shares of Stock that may be so withheld or surrendered shall be a number of shares of Stock that have an aggregate Fair Market Value on the date of withholding or repurchase of up to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for you in your relevant federal, state, foreign and/or local tax jurisdiction, including payroll taxes, that may be utilized without creating adverse accounting treatment with respect to the Award. The Company, in its discretion, may deny your request to satisfy its tax withholding obligations using a method described under subparagraph (a), (b) or (c) and require an alternative method of withholding. In the event the Company determines that the aggregate Fair Market Value of the Stock withheld as payment of any tax withholding obligation is insufficient to discharge that tax withholding obligation, then you must pay to the Company, in cash, the amount of that deficiency immediately upon the Company’s request.

12.Compliance with Securities and Other Applicable Laws. Notwithstanding any provision of this Agreement to the contrary, the issuance of Stock will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any stock exchange or market system upon which the Stock may then be listed. No Stock will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, Stock will not be issued hereunder unless (a) a registration statement under the Securities Act, is at the time of issuance in effect with respect to the Stock issued or (b) in the opinion of legal counsel to the Company, the Stock issued may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of

the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any Stock subject to the Award will relieve the Company of any liability in respect of the failure to issue such Stock as to which such requisite authority has not been obtained. As a condition to any issuance hereunder, the Company may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company. From time to time, the Board and appropriate officers of the Company are authorized to take the actions necessary and appropriate to file required documents with governmental authorities, stock exchanges, and other appropriate Persons to make Stock available for issuance.

13.Legends. The Company may at any time place legends referencing any restrictions imposed on the Stock pursuant to Sections 5 and 12 of this Agreement on all certificates representing Stock issued with respect to this Award.

14.Right of the Company and Subsidiaries to Terminate Services. Nothing in this Agreement confers upon you the right to continue in the employ of or performing services for the Company or any of its subsidiaries, or interfere in any way with the rights of the Company or any of its subsidiaries to terminate your employment or service relationship at any time subject to applicable law and the terms of any applicable employment agreement.

15.Furnish Information. You agree to furnish to the Company all information requested by the Company to enable it to comply with any reporting or other requirements imposed upon the Company by or under any applicable statute or regulation.

16.Remedies. The Company shall be entitled to recover from you reasonable attorneys’ fees incurred in connection with the successful enforcement of the terms and provisions of this Agreement whether by an action to enforce specific performance or for damages for its breach or otherwise to the extent allowed by applicable law.

17.No Liability for Good Faith Determinations. The Company and the members of the Board shall not be liable for any act, omission or determination taken or made in good faith with respect to this Agreement or the Performance Share Units granted hereunder.

18.Execution of Receipts and Releases. Any payment of cash or any issuance or transfer of Stock or other property to you, or to your legal representative, heir, legatee or distributee, in accordance with the provisions hereof, will, to the extent thereof, be in full satisfaction of all claims of such persons hereunder. In addition, the Company may require you or your legal representative, heir, legatee or distributee, as a condition precedent to such payment or issuance, to execute a general release of all claims in favor of the Company, any subsidiary and the foregoing entities’ respective predecessors, successors, employees, officers, directors, managers, members, stockholders or board members of the foregoing in such form as the Company may determine (the “Release”). If the Release is not executed and returned to the Company on or before the Release Expiration Date, and the required revocation period has not fully expired without revocation of the Release by you, then you shall not be entitled to settlement of any portion of the Award.  As used herein, the “Release Expiration Date” is that date that is twenty-one (21) days following the date upon which the Company delivers the Release to you (which shall occur no later than seven (7) days after your termination of employment) or, in the event that such termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), and you are age 40 or over as of your termination date, the date that is forty-five (45) days following such delivery date. The parties may agree in writing to extend the consideration timelines stated in this paragraph. In the event the period you are given to review,

execute and revoke a release provided pursuant to this Section 18 spans two calendar years, any payment to you pursuant to this Agreement will be made in the second calendar year.

19.Clawback. This Agreement is subject to any written clawback policies that the Company, with the approval of the Board or the Committee, may adopt to the extent not prohibited by applicable law. Any such policy may subject your Performance Share Units and amounts paid or realized with respect to the Performance Share Units under this Agreement and any other compensation (whether or not such other compensation is “incentive-based compensation” as defined in such policy) to which you are owed or entitled to outside of this Agreement, to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including but not limited to an accounting restatement due to the Company’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy adopted by the Company, including any policy to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the Securities and Exchange Commission and that the Company determines should apply to this Agreement and all such applicable compensation.

20.No Guarantee of Interests. Neither the Board nor the Company guarantee the Stock from loss or depreciation.

21.Company Records. Records of the Company or its subsidiaries regarding your period of employment or service, termination of service and/or employment and the reason(s) therefor, leaves of absence, re-employment, and other matters shall be conclusive for all purposes hereunder, unless determined by the Company to be incorrect.

(e)Extent of Restrictions and Your Acknowledgment. You acknowledge that the restrictions contained in this Section 24, including geographical and temporal restrictions, correctly set forth the understanding of the parties at the time this Agreement is entered into, are reasonable in all respects and necessary to protect the Confidential Information, goodwill and legitimate interests of the Company and its subsidiaries, do not interfere with public interests and will not cause you undue hardship, and that any violation will cause substantial injury to the Company and its subsidiaries. In the event of any such violation, the Company and each of its subsidiaries shall be entitled, in addition to any other remedy (whether at law or equity), to preliminary or permanent injunctive relief. You waive, to the maximum extent permissible by law, any defenses or other objections to such remedies or the enforceability of this Section 24. To the maximum extent permissible by law, if any court having jurisdiction shall find that any part of the restrictions set forth this Section 24 are unreasonable or unenforceable in any respect, it is the intent of the parties that the restrictions (or parts thereof) set forth herein shall not be terminated, but that the restrictions (or parts thereof) set forth in this Section 24 shall be modified and remain in full force and effect to the extent (as to time periods and other relevant factors) that the court shall find reasonable.

(f)Limitations. In the event any breach of the covenants set forth in this Section 24 comes to the attention of the Company, this Award and the Performance Share Units granted hereunder that have not at such time been settled shall be immediately forfeited to the Company and the Company shall take into consideration such breach in determining whether to recommend the grant of any future similar award to you, as a factor weighing against the advisability of granting any such future award to you. However, nothing in this Agreement will prevent you from lawfully: (i) initiating communications directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an

investigation by, any governmental authority regarding a possible violation of any law, (ii) responding to any inquiry or legal process directed to you from any such governmental authority, (iii) testifying, participating or otherwise assisting in any action or proceeding by any such governmental authority relating to a possible violation of law, or (iv) making disclosures or statements that are protected under the whistleblower provisions of applicable law or that are otherwise protected by applicable law. Nothing herein shall prevent you from making a disclosure that: (A) is made (1) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (2) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Further, an individual who files a lawsuit for retaliation by an employer of reporting a suspected violation of law may make disclosures without violating this Section 24 to the attorney of the individual and use such information in the court proceeding. Nothing in this Agreement requires you to obtain prior authorization before engaging in any conduct described in this paragraph, or to notify the Company or any of its subsidiaries that you have engaged in any such conduct.

25.Section 409A. It is intended that the Performance Share Units awarded hereunder shall comply with the requirements of Section 409A of the Code (and any regulations and guidelines issued thereunder), and this Agreement shall be construed and interpreted on a basis consistent with such intent. Payments shall only be made on an event and in a manner permitted by Section 409A of the Code, except as otherwise determined by the Committee. Each payment under this Agreement is considered a separate payment for purposes of Section 409A of the Code. This Agreement may be amended without your consent in any respect deemed by the Committee to be necessary in order to preserve compliance with Section 409A of the Code. All payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” under Section 409A of the Code. In no event may you, directly or indirectly, designate the calendar year of a payment. Notwithstanding anything in this Agreement to the contrary, if you are a “specified employee” under Section 409A of the Code at the time of separation from service and if payment of any amount under this Agreement is required to be delayed for a period of six months after the separation from service pursuant to Section 409A of the Code, payment of such amount shall be delayed as required by Section 409A of the Code, and the accumulated postponed amount shall be paid in a lump sum payment within 10 days after the end of the six-month period. If you die during the postponement period prior to the payment of the postponed amount, the accumulated postponed amount shall be paid to the personal representative of your estate within 60 days after the date of your death.
