## $1.3 Billion
Operating Cash Flow

## $724 Million
Returned to stockholders in 2025

## $4.7 Billion
Returned to stockholders since the 2022 Sinclair Oil Acquisition

#### Cash Return to Stockholders
We are managing our portfolio of assets to generate strong cash flows through the cycle and are pleased to have returned over $724 million to shareholders in the form of both dividends and share repurchases in 2025. Since completion of the Sinclair Oil acquisition in 2022, we have returned over $4.7 billion to shareholders, demonstrating our commitment to disciplined capital allocation and delivering returns for investors while maintaining the Company's investment-grade balance sheet.

#### Financial Highlights
The strong contributions from our diversified portfolio were a highlight in 2025, despite market headwinds and uncertainty caused by tariffs early in 2025. In fact, for 2025, we achieved record earnings in both our Marketing and Midstream businesses. The Company continued to maintain investment-grade ratings of BBB- at S&P, Baa3 at Moody's and BBB- at Fitch, and the resilience of our diversified portfolio positions HF Sinclair for long-term success. As we look forward, we are also evaluating several organic investment opportunities that will help the Company grow in its markets.

#### Operational Highlights
Our Refining business delivered sequential improvement in 2025, despite market headwinds and uncertainty caused by tariffs early in the year. We drove continued increases in refining throughput and capture, and reductions in operating costs, ultimately achieving record-low operating expense per throughput barrel. We completed planned turnarounds at our Tulsa, Parco and Puget Sound facilities, marking the conclusion of a full five-year turnaround cycle that has improved reliability and lowered the maintenance intensity of our portfolio of assets.

In our Marketing business, we continued to grow the Sinclair brand and footprint, adding a net of 117 sites during 2025, demonstrating our commitment to grow this business and increase the percentage of branded wholesale volumes across our refining system. Since completion of the Sinclair Oil acquisition in 2022, we have grown our site count by 20%. Additionally, we recently announced the formation of Green Trail Fuels, LLC, a new non-operating joint venture that will allow us to continue to accelerate growth.

#### 2026 PROXY STATEMENT (i)

------

##### [**Table of Contents**](#toc)

#### STOCKHOLDER LETTER
Our Lubricants & Specialties business performed well in spite of weakening base oil margins, supported by the continued execution of our forward integration strategy of placing more of our base oils into higher value finished and specialty products. We launched a Sinclair-branded lubricants offering in the United States, further strengthening our market position. Looking forward, we believe that our recent acquisition of Industrial Oils Unlimited will enhance our portfolio with diverse product lines.

Our Midstream business had a record earnings year, supported by lower operating costs from our continued integration efforts since the Holly Energy Partners, L.P. acquisition in 2023. In October, we announced the evaluation of a multi-phased plan to expand our midstream refined products footprint to address growing supply needs in the western U.S. We believe our geographic reach and infrastructure provide an advantaged position to quickly and efficiently deliver refined products where market needs are most acute.

Our Renewables business navigated a challenging year as the industry transitioned from the Blender's Tax Credit to the Producer's Tax Credit. Our team focused on what we can control by optimizing our low-carbon intensity feedstock mix and managing our costs. We believe the new regulatory framework will drive a tighter supply and demand balance over time, and we remain confident HF Sinclair is well-positioned to capitalize on that tailwind.

#### Safety
The safety of our people and communities remains our top priority. We firmly believe that working efficiently and effectively starts with working safely and reliably. We are grounded by our "Goal Zero" vision, which reflects our belief that safe production can be achieved each and every day. This is embedded in our culture and reinforced through continuous improvements in our processes, operations and workforce training. Our efforts are yielding results: over the past five years, our total recordable incident rate declined by 39%, reflecting our focus on incident prevention and operational excellence.

#### Your Vote Matters
We remain committed to the long-term interests of our stockholders. We hope your shares will be represented at the Annual Meeting, and I encourage you to vote early. This proxy statement provides important information regarding our Board and our governance and compensation practices to inform your vote.

On behalf of our Board and our employees, thank you for your trust and investment in HF Sinclair.

| &nbsp;&nbsp; **One HF Sinclair<br>Culture** | The One HF Sinclair Culture is based on the core values of Safety, Integrity, Teamwork, Ownership and Inclusion. These values guide our actions, community engagement and employee empowerment. Our people are at the heart of our success and we aim to instill integrity, teamwork and ownership at every level. Throughout 2025, we held leadership workshops focused on our value of Inclusion for frontline, senior and executive leadership roles. To help foster a culture of inclusion, we have five voluntary employee resource groups open to all employees: Women in Energy, Veterans in Energy, Family Caregivers in Energy, Toastmasters in Energy and Cultural Awareness in Energy. Each employee resource group focuses on supporting our employees and developing talent at HF Sinclair by fostering relationships through education, networking and leadership development opportunities. |
| &nbsp;&nbsp; **Goal Zero Vision** | The safety of our people and communities remains our top priority. We firmly believe that working efficiently and effectively starts with working safely and reliably. We are grounded by our "Goal Zero" vision, which reflects our belief that safe production can be achieved each and every day, and we set specific goals for workplace safety and measure attainment of those goals. Preventing serious incidents requires coordination across multiple disciplines, including process safety, occupational safety, asset reliability, investment, innovation and manufacturing. Our Operational Excellence Management System provides the framework through which we identify, monitor, mitigate and manage risks and drive consistency in our practices across the fleet. Over the past five years, our Occupational Safety and Health Administration's total recordable incident rate declined by 39%. |

|:---|:---|
| &nbsp;&nbsp; **Advancing Energy Innovation** | Innovation is central to our mission of delivering products that meet today's needs and anticipate tomorrow's demands. We regularly bring together cross-functional teams to identify opportunities that drive progress. Through collaboration, we develop innovative solutions that align with evolving consumer expectations. For example, in response to growing market demand for liquid cooling technologies for servers and computing components, we developed and launched INNOVATE<sup>™</sup>, which enables exceptional heat transfer capabilities while offering broad compatibility with materials required for immersed compute applications, supporting a more sustainable approach to data centers and crypto requirements. Additionally, through our Sinclair-branded retail stations, we provide a TOP TIER<sup>™</sup> gasoline that satisfies the requirements of today's most advanced engines and uses a high-quality additive called DINOCARE<sup>®</sup> to clean harmful deposits from engines and fuel systems, helping to provide better gas mileage and reduce maintenance costs. These products illustrate our commitment to providing the innovative solutions required for the future. |
| &nbsp;&nbsp; **Total Rewards** | The health of the Company is linked to the performance and health of our people. We want to inspire and empower our employees to feel confident in their long-term well-being and are committed to offering a comprehensive and competitive total rewards program for our employees, as benchmarked against our peers. While our benefit offerings vary depending on each country's market practices, they are designed to support employee health, financial and emotional needs, and include comprehensive coverage for health care, a competitive retirement savings benefit, vacation and holiday time and other income protection and work-life benefits. We also provide tools to help recognize and reward employee performance consistent with our One HF Sinclair Culture. |
| &nbsp;&nbsp; **Community Engagement & Ethics** | Our relationships with our stakeholders are essential to our success and our ability to operate. We strive to be a good neighbor by engaging in dialogue with communities in which we operate so we understand what's important to our stakeholders and respond to feedback. Our Global Ethics and Compliance program, led by our Chief Compliance Officer, establishes and reinforces our ethical standards through our Code of Business Conduct and Ethics (the "Code of Conduct"), among our other policies, including the Global Anti-Corruption and Third Party Due Diligence policies, the Global Privacy Policy and the Human Rights and Modern Slavery Policy. In 2025, 99.1% of active employees were trained and certified against our Code of Conduct. We also provide a confidential means for stakeholders to report suspected violations of law or company policies through our Speak and Be Heard reporting line. |

## Corporate Governance
The Board and senior management believe that one of their primary responsibilities is to promote a corporate culture of accountability, responsibility and ethical conduct throughout the Company. The Company is committed to maintaining the highest standard of business conduct and corporate governance, which we believe is essential to operating our business efficiently, maintaining our integrity in the marketplace and serving our stockholders.

Consistent with these principles, the Company has adopted the Code of Conduct and Corporate Governance Guidelines. These documents, together with our second amended and restated certificate of incorporation (the "Certificate of Incorporation"), amended and restated by-laws (the "By-Laws") and the Board committee charters, form the framework for our governance. Copies of the Code of Conduct, Corporate Governance Guidelines, Certificate of Incorporation, By-Laws, Audit Committee Charter, Compensation Committee Charter, Environmental, Health, Safety, and Public Policy Committee Charter, Finance Committee Charter and Nominating, Governance and Social Responsibility Committee Charter are publicly available on our website at *www.hfsinclair.com* and may also be obtained free of charge upon written request to HF Sinclair Corporation, 2323 Victory Avenue, Suite 1400, Dallas, Texas 75219, Attention: Vice President, Investor Relations.

**Board Leadership Structure** 

In accordance with our Corporate Governance Guidelines, our Board is responsible for selecting the Board leadership structure that is in the best interests of the Company. Our Board, during this time of transition, has determined that a leadership structure consisting of a combined role of Chief Executive Officer and Chairperson of the Board, together with a strong lead independent director, is appropriate for our Company. As Mr. Myers bears the primary responsibility for managing our day-to-day business, the combination of the role of Chief Executive Officer and Chairperson of the Board ensures that key business issues and stockholder interests are brought to the attention of our Board.

The Company's Corporate Governance Guidelines provide for the appointment of a lead director in the event the roles of Chairperson of the Board and Chief Executive Officer are combined. In recognition of his demonstrated leadership skills, the Board has appointed Mr. Echols as lead director. The lead director's responsibilities are set forth in the Company's Corporate Governance Guidelines and include coordinating with the independent directors in respect of each of the following:

• presiding over executive sessions of the Board's independent directors and at all meetings of the Board at which the Chairperson of the Board is not present;

• communicating matters discussed at the executive session to the Chairperson of the Board and Chief Executive Officer, as appropriate;

• serving as a liaison between the Chief Executive Officer, the Chairperson of the Board and the independent directors;

• advising and consulting with the Chairperson of the Board, the Chief Executive Officer and the chairperson of each committee regarding Board and committee meetings, as necessary, desirable or appropriate;

• calling meetings of the independent directors and encouraging or facilitating discussion among the directors to ensure the views of every director are heard and to achieve consensus;

• maintaining regular contact with the Chairperson of the Board and Chief Executive Officer to provide access for any issue that may arise and assist in communication, if appropriate, and to ensure that there is a steady, relevant, meaningful and effective information flow from management to the Board;

• approving in advance, in consultation with the Chairperson of the Board and Chief Executive Officer, agendas, schedules and related information for all meetings of the Board; and

• advising and consulting with the Chairperson of the Board and Chief Executive Officer as to the quality, quantity and timeliness of the information submitted by the Company's management to, and other communications with, the independent directors.

The Board has established a policy that its directors who are not officers or employees of the Company ("non-management directors") regularly meet in executive session, without members of management present. The Chairperson of the Board, or the lead director if the Chairperson of the Board is a member of management, presides at meetings of the non-management directors. In the event the Chairperson of the Board is a member of management and, if there is no lead director or the lead director is unable to attend, the non-management directors will designate an independent director to preside at the meeting. In the event the Company's

##### [**Table of Contents**](#toc)

#### CORPORATE GOVERNANCE
non-management directors include directors who are not independent under the NYSE listing requirements, then an executive session including only the independent directors will be held at least once per year. We believe that the foregoing structure, policies and practices, when combined with the Company's other governance policies and procedures, provide appropriate opportunities for oversight, discussion and evaluation of decisions and direction from the Board, and are in the best interests of our stockholders.

**Board and Committee Evaluations** 

The Board, acting through the Nominating, Governance and Social Responsibility Committee, conducts a self-evaluation at least annually to determine whether it is functioning effectively. The evaluation includes periodically considering the mix of skills and experience that directors bring to the Board to assess whether the Board has the necessary tools and background to perform its oversight function effectively.

The Nominating, Governance and Social Responsibility Committee has undertaken an effort to identify relevant skills, expertise, knowledge and diversity of opinion required of members of the Board to deliver long-term value to the stockholders of the Company. From that list, the Board developed a skills matrix as part of its efforts to represent each of the Company's Directors' identified skills, expertise, knowledge and diversity of opinion. See the "*Director Nominee Skills and Experience Matrix*" on page 8. The Nominating, Governance and Social Responsibility Committee and the Board review the matrix on an annual basis to confirm that it appropriately supports the Company's long-term strategy.

Each committee of the Board also conducts a self-evaluation at least annually and reports the results to the Board. The Nominating, Governance and Social Responsibility Committee may engage a third-party evaluator to assist with the evaluation process from time to time.

**Board Oversight of Risk Management** 

The Board oversees management of risk and receives a report from management on at least a quarterly basis. The Board regularly reviews information regarding the Company's credit, liquidity, business, operations and cybersecurity and technology, including the key risks associated with each of the foregoing. As described below, consistent with SEC regulations and NYSE requirements, the Board committees are also engaged in overseeing risk associated with the Company. While each committee is responsible for evaluating certain risks and overseeing the management of those risks, the full Board is ultimately responsible for overseeing the Company's risk exposures and management thereof, and the Board is regularly informed on these matters through committee and senior management presentations.

#### CORPORATE GOVERNANCE
**Director Independence** 

Board of Directors. NYSE listing requirements and our Corporate Governance Guidelines require that at least a majority of the Board meet the NYSE criteria for independence. The Board has determined that each of Mses. Ainsworth, Catalano and Johns and Messrs. Echols, Fernandez, Hardy, Knocke and Kostelnik is "independent" under the NYSE independence standards. Following his appointment as Chief Executive Officer and President, Mr. Myers is no longer independent because he is an employee of the Company. Mr. Matthews is not independent due to his continued service as Chair of the Board of Directors, and previously, Chief Operating Officer of REH Advisors following the closing of the Sinclair Transactions and the fact that members of his immediate family control REH Advisors, which owns more than five percent of HF Sinclair's common stock, that REH Company initially received as purchase consideration at the closing of the Sinclair Transactions. Please see "*Certain Relationships and Related Person Transactions*" on page 78 for a more detailed description of the ongoing relationship between the Company and REH Advisors in which Mr. Matthews may have a material interest.

Audit Committee. The Board has determined that each member of the Audit Committee is "independent" as defined by the NYSE listing standards and Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Compensation Committee. The Board has determined that each member of the Compensation Committee is "independent" as defined by the NYSE listing standards. For each member of the Compensation Committee, the Board considered all factors specifically relevant to determining whether a director has a relationship to the Company that is material to that director's ability to be independent from management in connection with the duties of a Compensation Committee member, including the sources of such director's compensation, such as any consulting, advisory or other compensatory fees paid by the Company, and whether the director has an affiliate relationship with the Company, a subsidiary of the Company or an affiliate of a subsidiary of the Company.

Nominating, Governance and Social Responsibility Committee. The Board has determined that each member of the Nominating, Governance and Social Responsibility Committee is "independent" as defined by the NYSE listing standards.

Environmental, Health, Safety, and Public Policy Committee. The Board has determined that each member of the Environmental, Health, Safety, and Public Policy Committee is "independent" as defined by the NYSE listing standards.

Finance Committee. The Board has determined that each member of the Finance Committee, other than Mr. Matthews, is "independent" as defined by the NYSE listing standards.

Independence Determination. In making its independence determinations, the Board considered certain transactions, relationships and arrangements. In determining Mr. Knocke's independence, the Board considered that Mr. Knocke is a non-controlling manager and member of TCTC, and Mr. Knocke is also a Principal of TCTC (which may be deemed to beneficially own 6.97% of the Company's common stock) and holds various other positions with TCTC's subsidiaries. The Board determined that this relationship does not impair the independence of Mr. Knocke.

**Director Nominations** 

#### Qualifications
The Nominating, Governance and Social Responsibility Committee may engage a search firm to assist with identifying qualified nominees for the Board. In considering nominees for election as director, the Nominating, Governance and Social Responsibility Committee considers a number of criteria approved by the Board and related to relevant skills, expertise, knowledge and variety of opinion that may be desired, necessary or appropriate for inclusion on the Board. The Nominating, Governance and Social Responsibility Committee is also responsible for recommending the nomination of incumbent directors it deems appropriate for re-election to the Board and, if applicable, reappointment to any committees of the Board on which such director serves. Pursuant to our Corporate Governance Guidelines, the Nominating, Governance and Social Responsibility Committee will not recommend to the Board the nomination of any director or nominee who has attained or will attain the age of 75 prior to the annual meeting at which he or she would be elected or re-elected. The Board may approve an exception to this policy on a case-by-case basis.

Characteristics expected of all directors include integrity, exceptional talent and judgment, and the ability and willingness to commit adequate time to the Board. In evaluating the suitability of individual board members, the Nominating, Governance and Social Responsibility Committee takes into account many factors, including the candidate's independence, the skills enumerated in the Director Nominee Skills and Experience Matrix, knowledge of the communities in which the Company does business, the Company's industry, or other industries relevant to the Company's business or other organizations of comparable size and personal qualities, such as background and reputation. The Board also considers the ranges of background, knowledge, professional and lived experiences, skills, viewpoints, geography and other relevant factors when evaluating candidates and is committed to, when conducting

#### CORPORATE GOVERNANCE
a formal search to recruit director candidates from outside the Company as potential nominees to join the Board, endeavoring to include, and instructing any third-party search firm engaged to assist in seeking candidates for the Board to include, a wide range of highly qualified candidates, consistent with the previously identified considerations, in any initial pool from which director candidates are selected.

Our Corporate Governance Guidelines require an annual review by the Nominating, Governance and Social Responsibility Committee of each director's commitments on other public company boards. Following its review in 2026, the Nominating, Governance and Social Responsibility Committee has determined that, in its view, no director currently has time commitments that would prevent such director from properly discharging his or her duties as a director.

In connection with and effective as of the closing of the Sinclair Transactions, HF Sinclair entered into a stockholders agreement (the "Stockholders Agreement") by and among HF Sinclair, REH Company and the stockholders of REH Company (each a "Stockholder" and along with each of their permitted transferees, collectively, the "REH Parties"). In June 2024, REH Company transferred its HF Sinclair shares to its affiliate and permitted transferee, REH Advisors, which executed a joinder to the Stockholders Agreement. Pursuant to the Stockholders Agreement, the REH Parties were entitled to designate for election or appointment, and did designate, (i) two persons (the "Designees") to the Board at the closing of the Sinclair Transactions and for so long as the REH Parties beneficially own common stock constituting not less than 15% of all outstanding HF Sinclair common stock and (ii) one person to the Board for so long as the REH Parties beneficially own less than 15% but more than or equal to 5% of all outstanding HF Sinclair common stock. All Designees must possess the director characteristics and qualifications contained in the By-Laws and Corporate Governance Guidelines and expected of all other directors of the Board, as described in the immediately preceding paragraph above. In addition, at all times at least one Designee, if there is any, shall possess significant management experience in the refining industry, as determined by the Board in its reasonable discretion. The REH Parties currently have the right to designate one person for election or appointment to the Board and Mr. Matthews currently serves as a Designee of the REH Parties on the Board.

#### Stockholder Director Nominations to be Presented at the Annual Meeting
The Nominating, Governance and Social Responsibility Committee will consider recommendations of potential director candidates from stockholders based on the same criteria as a candidate identified by the Nominating, Governance and Social Responsibility Committee. Stockholders may submit such a recommendation by sending a letter to the Secretary of the Company at the Company's principal office address. The mailing envelope must contain a clear notation indicating that the enclosed letter is a "Director Nominee Recommendation."

To be considered, recommendations must be submitted in writing no less than 90 days and no more than 120 days prior to the anniversary date of the immediately preceding annual meeting of stockholders in compliance with the notice procedures and informational requirements set forth in Article III, Section 12 of the By-Laws. A stockholder's notice must include the following:

• a written statement by the director candidate agreeing to being named in the Company's proxy materials and to serve a full term as a member of the Board if nominated and elected;

• a representation as to whether or not the stockholder recommending the director candidate intends, or is a part of a group that intends, to (1) deliver a proxy statement and/or form of proxy to holders of at least the percentage of the outstanding capital stock of the Company required to elect the director candidate; (2) otherwise solicit proxies or votes from stockholders in support of such nomination; and (3) solicit proxies in support of a director candidate other than the Company's nominees in accordance with Rule 14a-19 promulgated under the Exchange Act, and if so, provide the notice and other information required in Rule 14a-19 promulgated under the Exchange Act;

• all other information relating to the nominating stockholder or director candidate that would be required to be disclosed in a proxy statement relating to an election of directors, or that is otherwise required by Regulation 14A under the Exchange Act or Article III, Section 12 of the By-Laws; and

• such other information relating to the proposed nomination as the Company may reasonably request to determine whether such proposed nomination is a proper matter for stockholder action.

**Director Compensation** 

The Compensation Committee annually evaluates the compensation program for our non-management directors. In making its recommendation to the Board for non-management director compensation, the Compensation Committee reviews the form and amount of compensation paid to directors by the Company's compensation peer group and benchmark market data provided by the compensation consultant. The director compensation peer group is the same as the compensation peer group considered by the Compensation Committee in setting executive compensation for 2025 and consisted of 17 companies as described in detail below under "*Compensation Discussion and Analysis—Market Review*." Based on recommendations from the Compensation Committee, the Board approved the components of non-management director compensation as set forth below.

#### Cash Retainers
Cash retainers are paid to the non-management directors on a quarterly basis during their respective time serving as a director or committee member. Members of the Board who also serve as our officers or employees do not receive additional compensation in their capacity as directors.

We also reimburse directors for all reasonable expenses incurred in attending Board meetings, Board committee meetings and director continuing education sessions upon submission of appropriate documentation. Meeting fees are not paid for attendance at Board meetings or Board committee meetings.

#### Equity Awards
Non-management directors receive an annual equity award grant in the form of restricted stock units having a fair market value of approximately the dollar amount of the equity award approved by the Board on the date of grant. These annual grants are made in the fourth quarter of the year preceding the year to which the award relates in order to align the timing of the equity award grants with the timing of the other compensation decisions made for non-management directors and with the timing of long-term equity incentive award grants for our executive officers.

Continued service on the Board through the stated vesting date for the restricted stock units, which is in most cases approximately one year following the date of grant, is required in order for the restricted stock units to become vested. The restricted stock units granted in November 2024 for the 2025 fiscal year vested on December 1, 2025. The restricted stock units granted in November 2025 for the 2026 fiscal year will vest on December 1, 2026 (or on the first business day thereafter if such date falls on a weekend). Accelerated vesting of outstanding restricted stock units will occur upon a change in control (subject to the director serving as a member of the Board immediately prior to the change in control) or the director's death, disability or retirement. Settlement of the restricted stock units in shares of our common stock occurs within 30 days of the event that caused the restricted stock units to vest. Directors do not have the rights of a stockholder with respect to the shares underlying the restricted stock units until the award vests and is settled in shares. However, directors are entitled to the payment of dividend equivalents on outstanding restricted stock units in the form of cash in an amount equal to the dividends that would have been paid with respect to the underlying shares. These dividend equivalents are not subject to forfeiture.

(1) In November 2025, the Board set director compensation for the 2026 fiscal year. There were no changes to director compensation for the 2026 fiscal year from the 2025 fiscal year.

(2) The annual award is comprised of a number of restricted stock units equal to the dollar amount of the award divided by the market closing price of a share of our common stock on the date of grant, with the number of restricted stock units rounded up in the case of fractional shares. The annual award is made in the fourth quarter of the year preceding the year to which the award relates.

(3) A director serving as chairperson of a committee receives an annual cash retainer for service in that role in addition to the annual cash retainer for service as a member of the committee.

#### Nonqualified Deferred Compensation
For 2025, our non-management directors were eligible to participate in the HF Sinclair Corporation Executive Nonqualified Deferred Compensation Plan, which is not tax-qualified under Section 401 of the Internal Revenue Code (the "Code") and allows participants to defer receipt of certain compensation (the "NQDC Plan").

The NQDC Plan allows non-management directors the ability to defer up to 100% of their cash retainers for a calendar year. Participating directors have full discretion over how their contributions to the NQDC Plan are invested among the offered investment options, and earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. We do not subsidize a participant's earnings under the NQDC Plan. Messrs. Fernandez, Knocke and Myers and Ms. Johns participated in the NQDC Plan in 2025 and elected to defer all of their cash retainers for fiscal year 2025.

For additional information on the NQDC Plan, see "*Compensation Discussion and Analysis—Components of our Executive Compensation Program During 2025—Retirement Benefits and Perquisites—Retirement Plans—Deferred Compensation Plan*" and "*Executive Compensation—Nonqualified Deferred Compensation*."

For 2025, our non-management directors were also eligible to participate in the HF Sinclair Corporation Directors Stock Compensation Deferral Plan (the "Director Stock Deferral Plan"). The Director Stock Deferral Plan is a nonqualified plan under Section 401 of the Code that allows participant directors to defer receipt of current compensation in order to provide retirement and other benefits on behalf of

2026 PROXY STATEMENT 33

#### THE BOARD, ITS COMMITTEES AND ITS COMPENSATION
the participant directors. The Director Stock Deferral Plan allows non-management directors to defer up to 100% of their restricted stock unit award. During 2025, Messrs. Fernandez, Hardy, Knocke, Kostelnik and Myers and Ms. Johns participated in the Director Stock Deferral Plan and elected to defer their 2025 restricted stock unit awards. Each of Messrs. Fernandez, Hardy, Knocke, Kostelnik and Myers and Ms. Johns also elected to defer their 2026 Director Awards (as defined below).

Participant directors are not eligible to receive a matching contribution with respect to their elective deferrals. While deferred, a participant director's account will continue to track the value of our common stock. A participant director's deferred compensation account will be distributed in a lump sum in the form of unrestricted common stock upon the earliest to occur of a separation from service, disability or death.

#### Stock Ownership and Retention Policy for Non-Management Directors
Non-management directors are expected to acquire and hold during their service on the Board shares of our common stock equal in value (taking into account the value of common stock owned and outstanding restricted stock unit awards held by the individual) to at least five times the annual Board cash retainer paid to our non-management directors (excluding any retainer paid for service on a Board committee or for service as a chair of a Board committee). Directors have five years from their initial election to the Board to meet the target stock ownership requirements.

Directors are required to continuously own sufficient shares to meet the stock ownership requirements once attained. Until the directors attain compliance with the stock ownership policy, the directors will be required to hold 50% of the shares of common stock received from any equity award. If a director attains compliance with the stock ownership policy and subsequently falls below the requirement because of a decrease in the price of our common stock, the director will be deemed in compliance provided that the director retains the shares then held.

As of December 31, 2025, all of our non-management directors were in compliance with the stock ownership policy or were within the five-year grace period provided under the stock ownership policy.

#### Anti-Hedging and Anti-Pledging Policy
All of our directors are subject to our Insider Trading Policy which, among other things, prohibits directors from entering into short sales or hedging or pledging shares of our securities. The anti-hedging policy contained in our Insider Trading Policy specifically prohibits directors and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Company securities (or derivatives thereof), including through, among other mechanisms, the purchase of financial instruments (such as prepaid variable forward contracts, equity swaps, collars, and exchange funds) or other transactions that are designed to hedge or offset any decrease in the market value of shares of our securities (or derivatives thereof). Additionally, all employees, including our named executive officers, and all members of our Board, are prohibited from holding our securities in a margin account or otherwise pledging securities as collateral for a loan.

**Director Compensation Table** 

The table below sets forth the compensation earned by each of our non-management directors in 2025. Directors who are also our employees do not receive additional compensation for their service on our Board. In accordance with SEC executive compensation disclosure rules, Mr. Go's compensation is reported in the "Summary Compensation Table" on page 57.

(1) Certain amounts reported as earned or paid in this column for Messrs. Myers, Fernandez and Knocke and Ms. Johns were deferred into our NQDC Plan.

#### THE BOARD, ITS COMMITTEES AND ITS COMPENSATION
(2) Amounts in this column represent the aggregate grant date fair value of 2,493 restricted stock units granted to each non-management director on November 12, 2025 for the 2026 fiscal year (the "2026 Director Awards"), determined in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718, Compensation—Stock Compensation, excluding the effect of estimated forfeitures. See Note 8 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

Because the 2026 Director Awards were granted during 2025, they are reported in the "Stock Awards" column of the Director Compensation Table for 2025 rather than 2026 in accordance with SEC rules. The annual restricted stock unit awards for the 2025 fiscal year were granted on November 13, 2024 and were reported in the "Stock Awards" column of the Director Compensation Table for 2024 rather than 2025 in accordance with SEC rules. For additional information regarding the annual restricted stock unit awards and grant process for non-management directors, please see "*—Equity Awards*" above. <br>

The 2026 Director Awards will vest on December 1, 2026 (or on the first business day thereafter if such date falls on a weekend), subject to continued service on the Board. As of December 31, 2025, the 2026 Director Awards were the only outstanding equity awards held by our non-management directors. As noted above, Messrs. Fernandez, Hardy, Knocke, Kostelnik and Myers and Ms. Johns each deferred their 2026 Director Award. <br>

## Advisory Vote on the Compensation of Our

## Named Executive Officers (Proposal 2)
Section 14A(a)(1) of the Exchange Act requires that we provide our stockholders with the opportunity to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed pursuant to the compensation disclosure rules of the SEC, including the compensation discussion and analysis, the compensation tables and any related material contained in this proxy statement.

In accordance with the preference expressed by our stockholders at our annual meeting in 2023, the Board determined that we would provide this opportunity annually until the next non-binding stockholder advisory vote on the frequency of future advisory votes on executive compensation which will occur at the 2029 Annual Meeting of Stockholders. As described in detail under the heading "*Compensation Discussion and Analysis*," our executive compensation programs are primarily designed to (i) attract, motivate and retain our named executive officers, who are critical to our success, (ii) provide incentives for our named executive officers to achieve and exceed our operational, financial and strategic goals and (iii) align the interests of our named executive officers with those of our stockholders. Under these programs, compensation for our named executive officers is tied to performance, including our financial results and stockholder returns. Please read the information under "*Compensation Discussion and Analysis*," and review the compensation tables and narratives that follow, for additional details about our executive compensation programs, including information about the compensation of our named executive officers in 2025.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the compensatory philosophy, policies and practices described in this proxy statement. Because your vote is advisory, it will not be binding on the Compensation Committee, the Board or the Company. However, the Board and the Compensation Committee will review the voting results and take those results into consideration when making future decisions regarding executive compensation.

**Required Vote and Recommendation** 

The advisory vote on the compensation of named executive officers requires the approval of a majority of the votes cast on the proposal.

However, in addition to the changes that occurred during 2025, as previously announced, on February 17, 2026, Mr. Go requested to take a voluntary leave of absence from his duties as Chief Executive Officer and President of the Company, and on February 24, 2026, Mr. Atanasov requested to take a voluntary leave of absence from his duties as Executive Vice President, Chief Financial Officer of the Company. Mr. Go and Mr. Atanasov remain on leave as of the date of this proxy statement.

The compensation of our named executive officers is presented in the tables and related information provided under "*Executive Compensation*" below.

#### 2025 Business Highlights
• Full year 2025 net income attributable to HF Sinclair stockholders of $579 million, or $3.08 per diluted share, and adjusted net income of $951 million, or $5.06 per diluted share

• Operating cash flow of approximately $1.3 billion

• Ended the year with a strong balance sheet, including approximately $978 million in cash and cash equivalents and approximately $2.769 billion in long-term debt

• Returned approximately $724 million to stockholders through dividends and share repurchases

• Over the past five years, our combined total recordable injury rate declined by 39%

These results were taken into account in awarding 2025 annual incentive bonuses to our named executive officers. We believe the total compensation received by our named executive officers for 2025 was reflective of Company financial and operational performance for the year.

#### Say-on-Pay Vote
Our stockholders have the opportunity to cast an advisory vote on executive compensation annually. At our last three annual meetings of stockholders in 2025, 2024 and 2023, approximately 96% of the votes cast by our stockholders were voted in support of our executive pay program. The Compensation Committee believes these results affirm our stockholders' support of our approach to executive compensation, and the Compensation Committee did not make any material changes to our executive compensation program in 2025 based on the results of the 2025 advisory vote. The Compensation Committee will continue to consider the outcome of the Company's say-on-pay votes when making future compensation decisions for the named executive officers.

|  What We Do |
| &nbsp;&nbsp; <br> ✓ We pay for performance. For 2025, approximately 91% of our then CEO's annual target compensation, and approximately 79% of our other average NEO annual target compensation, was variable and paid based upon attainment of pre-established financial and operational performance objectives and, in certain circumstances, the performance of our common stock relative to our industry peers.<sup>(1)</sup><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For 2025, approximately 77% of our then CEO's target compensation, and approximately 61% of our other average NEO target compensation, was equity-based awards, of which 65% of our then CEO's and 46% of our other NEOs' awards vest based on the Company's stock and financial performance relative to that of our industry peers over a three-year performance period.<sup>(1)</sup><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In 2025, 100% of our then CEO's, and our other NEOs', annual bonus was based on the Company's financial and operational performance as measured against pre-established goals and, in certain circumstances, relative to our industry peers. Annual bonuses paid to our executive officers may be capped at 50% of the individual's target bonus if the Company does not achieve positive operating income on a consolidated basis.<br>✓ We seek independent advice. We engage independent consultants to review executive compensation and provide advice to the Compensation Committee.<br>✓ We provide limited perquisites. We provide limited perquisites and other personal benefits to our executive officers*.*<br>✓ We provide for "double trigger" provisions in agreements with our executives. Our equity award agreements and change in control severance agreements with our executives contain "double trigger" provisions.<br>✓ We have stock ownership requirements. We maintain a stock ownership policy for officers and directors. Our Chief Executive Officer is required to own 6x his base salary in Company stock.<br>✓ We have stock retention requirements. We require our officers and directors to hold 50% of the shares they receive from equity awards until they are in compliance with the stock ownership policy.<br>✓ We maintain a Dodd-Frank and NYSE compliant clawback policy and discretionary clawback policy. Our Dodd-Frank Policy (as defined below) requires the return of annual and long-term incentive compensation upon the occurrence of an accounting statement resulting from material noncompliance with any financial reporting requirement and our discretionary Misconduct Policy (as defined below) may require the return of annual and long-term incentive compensation upon the occurrence of certain acts of misconduct.<br>✓ We seek stockholder input. We provide our stockholders with the opportunity to provide an advisory vote on our executive compensation program on an annual basis. |
| <br> (1) Target compensation is comprised of our three main compensation elements: base salary, annual incentive cash bonuses and equity incentive awards. Percentages will not tie to<br>the Summary Compensation Table since the majority of equity awards for 2025 were granted in November 2024.<br>|

#### COMPENSATION DISCUSSION AND ANALYSIS
**Philosophy and Objectives of Executive Compensation Program** 

#### Pay-for-Performance Philosophy
Our compensation programs are designed to remunerate our named executive officers in accordance with a pay-for-performance philosophy. As such, the compensation programs are intended to provide incentives to our named executive officers, as well as other employees, to maximize operational performance and stockholder value, which in turn affects the overall compensation earned by our management.

Generally, each named executive officer's total direct compensation is heavily influenced by Company and individual performance measures. The majority of our named executive officers' compensation is performance-based, at-risk pay in the form of both short-term and long-term incentives.

#### Objectives
In designing the compensation program for our named executive officers, the Compensation Committee sought to achieve the following key objectives:

• Attract and Retain Talented and Productive Executives. The compensation program should provide each named executive officer with a total compensation opportunity that is competitive within the market. This objective is intended to ensure that we are able to attract and retain executive officers while maintaining an appropriate cost structure.

• Motivate Executives. The compensation program should provide incentives for our named executive officers to achieve and exceed our financial and operational goals.

• Align with Stockholders. The compensation program should align named executive officers' interests with those of our stockholders, promoting actions that will have a positive long-term impact on total stockholder return.

• Transparent Compensation. The elements of the compensation program should be easily understood by both our executive officers and our stockholders.

#### COMPENSATION DISCUSSION AND ANALYSIS
**Role of Compensation Committee in Establishing Compensation** 

The Compensation Committee administers our executive compensation programs. The role of the Compensation Committee is to review and approve the compensation to be paid to executive officers, including the named executive officers, and to review the compensation policies and practices for all of our employees to verify that they do not create unreasonable risks for us or our stockholders.

In setting compensation for executive officers, the Compensation Committee considers, among other things, recommendations by its independent compensation consultant and management and the compensation of similarly situated executives in comparable businesses. In addition, the Compensation Committee annually reviews total compensation paid to the named executive officers for the prior year and, with the assistance of management, proposes long-term incentive compensation awards.

**Role of Executive Officers in Establishing Compensation** 

Our Chief Executive Officer makes compensation recommendations to the Compensation Committee for the executive officers, including the named executive officers (except with respect to his own compensation). Management provides financial and compensation data to the Compensation Committee for its review in setting compensation and gives guidance as to how the data impacts performance goals set by the Compensation Committee. This data includes:

• our financial performance for the current year compared to the preceding year;

• performance evaluations of the named executive officers (other than for the Chief Executive Officer, who is evaluated by the Compensation Committee); and

• compensation provided to the named executive officers in previous years.

Given the day-to-day familiarity that the Chief Executive Officer has with the work performed by the other named executive officers, the Compensation Committee values his recommendations. However, the Compensation Committee makes all final decisions as to the compensation of the named executive officers.

**Role of the Compensation Committee Consultant in Establishing Compensation** 

As in prior years, the Compensation Committee engaged Meridian as the independent compensation consultant to the Compensation Committee for 2025 to provide advice relating to executive and non-employee director compensation matters. In determining 2025 compensation for the named executive officers, Meridian provided external context and other input to the Compensation Committee prior to the Compensation Committee approving salaries and fees, awarding bonuses and equity compensation or establishing awards for the upcoming year. Meridian provided information and advice to the Compensation Committee with respect to matters related to executive compensation related trends, regulatory and legislative developments, review of the compensation comparison peer group and Incentive Peer Group (as defined below) for annual incentive cash compensation and long-term incentive plan performance comparisons, and assessment of non-employee director compensation in relation to peers. As discussed above under "*The Board, its Committees and its Compensation—Board Committees—Compensation Committee*," the Compensation Committee has concluded that we do not have any conflicts of interest with Meridian.

**Market Review** 

We regularly compare our executive compensation program with market information regarding salary levels, target incentive awards and program design. The purpose of these analyses is to provide a frame of reference in evaluating the reasonableness and competitiveness of our executive compensation as compared to that of companies within the energy industry that are generally comparable in size and scope of operations to us. As detailed below, our compensation peer group includes refining companies as well as companies that are in comparable chemical and processing-oriented industries due to the limited number of comparably-sized refiners.

Market pay levels for named executive officers are obtained from the SEC filings of the companies in our compensation peer group and published compensation surveys, which cover our industry sector and labor market. As a component of setting 2025 compensation, the Compensation Committee reviewed a study of competitive target compensation opportunities to our named executive officers prepared by Meridian.

#### 2026 PROXY STATEMENT 43

#### COMPENSATION DISCUSSION AND ANALYSIS
The following companies comprised the 2025 compensation peer group reviewed and approved by the Compensation Committee:

• Alcoa Corporation

• Celanese Corporation

• Delek US Holdings, Inc.

• DuPont De Nemours, Inc.

• Eastman Chemical Company

• Ecolab Inc.

• International Paper Company

• LyondellBasell Industries N.V.

• Nucor Corporation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• PBF Energy Inc.

• PPG Industries Inc.

• The Goodyear Tire & Rubber Company

• The Mosaic Company

• The Sherwin-Williams Company

• United States Steel Corporation

• Westlake Chemical Corporation

• World Kinect Corporation

The 2025 compensation peer group is comprised of the same companies used in the 2024 compensation peer group. The 2025 compensation peer group is different than the 2025 Incentive Peer Group, which is used as a market comparison when determining payouts of certain performance-based incentive awards granted to named executive officers. See *"—2025 Executive Compensation Decisions—Long-Term Equity Incentive Target Value—Performance Share Unit Awards*" for a further discussion of the 2025 Incentive Peer Group and the reasons for the differences from the 2025 compensation peer group.

**2025 Executive Compensation Decisions** 

The Compensation Committee generally established 2025 target total direct compensation, including base salary, annual incentive cash compensation and long-term equity incentive compensation awards, for our named executive officers at pay levels in a range around the market median, however, executives may be positioned above or below this range for various reasons such as experience, tenure or performance. In the fourth quarter of 2024, the Compensation Committee utilized the market data provided by Meridian and internal evaluations of Messrs. Go, Atanasov, Ledbetter and Nitcher and Ms. Pompa to establish target total compensation opportunities for those executives that were consistent with this objective.

Based on the annual review of compensation, the Compensation Committee believes that 2025 compensation for the named executive officers reflects appropriate allocation of compensation between salary, bonuses and equity compensation, with a majority of the compensation being performance-based, at-risk pay in the form of both short-term and long-term incentives.

#### Base Salary
The Compensation Committee reviews base salaries annually and establishes base salaries that are competitive with the market to provide our named executive officers with compensation consistent with their responsibilities, experience, and individual performance, as well as with our peers. In the fourth quarter of 2024, the Compensation Committee conducted its annual review of base salaries and market survey data for our named executive officers and determined that increases in the base salaries for the named executive officers were warranted based on factors such as our financial performance, market levels of compensation for comparable positions and internal pay equity.

The following table sets forth the base salaries for 2024 and 2025 of our named executive officers:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Name and Title (as of December 31, 2025) | 2024<br>Base Salary | 2025<br>Base Salary<sup>(1)</sup> |
| &nbsp;&nbsp; ***Timothy Go***<br> Chief Executive Officer and President | $1100000 | $1200000 |
| &nbsp;&nbsp; ***Atanas H. Atanasov***<br> Executive Vice President and Chief Financial Officer | $675000 | $740000 |
| &nbsp;&nbsp; ***Eric L. Nitcher***<br> Executive Vice President, General Counsel | $620000 | $640000 |
| &nbsp;&nbsp; ***Valerie Pompa***<br> Executive Vice President, Operations | $575000 | $630000 |
| &nbsp;&nbsp; ***Steven C. Ledbetter***<br> Executive Vice President, Commercial | $525000 | $540000 |

#### COMPENSATION DISCUSSION AND ANALYSIS

#### Annual Incentive Cash Compensation
Under our annual incentive cash compensation program, named executive officers are eligible for cash bonuses that are designed to reward achievement of financial and business goals that are aligned with stockholders' interests. Annual incentive cash awards for our named executive officers are reviewed annually and are variable based on the Company's financial and operational performance as measured against pre-established goals and, in certain circumstances, relative to our industry peers.

The performance period for the 2025 annual incentive cash compensation program commenced on October 1, 2024 and ended on September 30, 2025. In the fourth quarter of 2024, the Compensation Committee approved target award levels as well as all other terms of the annual incentive cash compensation awards granted to our then-current named executive officers for 2025.

In setting the target award levels and the other terms of the annual incentive cash compensation awards for the named executive officers, the Compensation Committee reviewed annual incentive market data and trends for the Company's compensation peer group and industry provided by, and considered the recommendation of, its independent compensation consultant, Meridian.

The Compensation Committee made the following enhancements to the annual cash incentive program for the 2025 year:

• The Strategic & Individual metric applicable to our named executive officers (other than our Chief Executive Officer) was eliminated in order to harmonize weighting for all executive participants, so that the performance measure percentages applicable to all executive officers' annual cash incentive bonus is as follows: Financial metric (60%); and Operational metric (40%);

• Thresholds and targets for the two components of the Financial metric, Available Free Cash Flow and AICP Adjusted EBITDA, were adjusted to align with the Company's projections and forecasts for the 2025 year; and

• Targets for Operational metrics, such as process safety, perfect environmental days and reliability, were adjusted for certain of the Company's business segments to incentivize improved performance.

The enhancements described above more closely align the Company's annual cash incentive program metrics with the Company's financial and operating performance measures and objectives, the practices of the Company's compensation peer group and broader market trends regarding metrics in annual cash incentive programs.

The annual cash incentive compensation awards are subject to the performance measures set forth in the table below. However, the awards are subject to an overall bonus hurdle that may limit the named executive officers' target bonus to 50% of the individual's target bonus if the Company does not achieve positive "adjusted operating income" for the applicable fiscal year. Adjusted operating income of the Company means earnings before interest and taxes as reported in the Company's audited consolidated financial statements and is calculated as net income (loss) attributable to HF Sinclair stockholders plus (i) interest expense, net of interest income, and (ii) income tax expense plus adjustments for extraordinary items, other unusual or non-recurring items, each as determined in accordance with generally accepted accounting principles and identified in the financial statements, notes to the financial statements or management's discussion and analysis. The bonus hurdle better aligns executive rewards with shareholder returns and reinforces our objective of paying for performance. Despite any bonus hurdles or performance deemed earned for the year, the Compensation Committee will continue to retain full discretion to pay, not pay or modify all annual incentive cash compensation awards.

#### 2025 Annual Incentive Award Opportunities at Minimum, Target and Maximum Payouts
The following table sets forth the minimum, target and maximum award opportunities (as a percentage of annual base salary) for our applicable named executive officers for 2025, and the portion of each named executive officer's target award opportunity that is allocated to each performance measure (as a percentage of the target award opportunity).

#### COMPENSATION DISCUSSION AND ANALYSIS
To facilitate timely determination of award payouts, the measurement period for each of the metrics above covers four consecutive quarters starting with the fourth quarter of the preceding year (2024) and ending with the third quarter of the following year (2025). The award payout for each named executive officer is calculated based on the actual base salary earnings received by each named executive officer during the measurement period.

#### Performance Measures
The 2025 annual incentive awards were subject to our achievement of specified levels of performance with respect to financial and operational performance measures for our named executive officers. The following table sets forth the various components for each measure.

(1) Available Free Cash Flow is measured as Cash Flow from Operating Activities, less non-discretionary capital spending, dividends to Company stockholders and amounts attributable to our non-controlling interests.

(2) Calculation of EBITDA for purposes of the annual cash incentive awards ("AICP Adjusted EBITDA") differs from the calculation of EBITDA as reported in our financial statements. See Appendix A for the specific adjustments and the reconciliation of AICP Adjusted EBITDA to net income, the most directly comparable generally accepted accounting principle ("GAAP") financial measure, for the periods presented.

(3) The ESG metric is divided into three equally weighted measures. The payout is determined by a performance system (described below), where events for each site are measured and accrued on a quarterly basis and all four quarters of the performance period are aggregated and averaged by segment, segment results are then weighted according to their respective segment weighting and all segments are aggregated. Sites that meet the performance criteria in three quarters or more are eligible for performance multipliers ranging from 1.5 to 2.5.

(4) For the Refining, Renewables and Lubricants & Specialties segments, the occupational safety metric is based on the number of employee and contractor recordables, with a quarterly target for each site of zero employee or contractor recordables. For the Refining, Renewables and Lubricants & Specialties segments, the process safety metric is

46 ![LOGO](g71037g04a01.jpg)

------

##### [**Table of Contents**](#toc)

#### COMPENSATION DISCUSSION AND ANALYSIS
based on the number of Tier 1 and Tier 2 process safety events, with a quarterly target for each site (other than the Cheyenne and the Artesia pre-treatment unit ("PTU")) of zero Tier 1 and one Tier 2 event. The target for the Cheyenne and the Artesia PTU is zero Tier 1 events and zero Tier 2 events per quarter. Management has discretion to apply a negative adjustment to the overall annual site payouts as a result of a high severity event or incident rate. The occupational safety and process safety metrics are equally weighted, and, combined, represent one-third of the weighting of the ESG metric. For actual performance for the 2025 performance period, see the table below.

(5) For the Refining, Renewables and Lubricants & Specialties segments, the environmental metric is based on the number of perfect environmental days, with performance measured quarterly at each refinery or facility, as applicable. Management has discretion to apply a negative adjustment to the overall annual site payouts as a result of a high severity event or incident rate. For actual performance for the 2025 performance period, see the table below.

(6) Greenhouse Gas Emissions reduction is based on the Company's goal to reduce the Company's net greenhouse gas ("GHG") emissions intensity by 25% by 2030 as compared to 2020 levels. GHG intensity is measured as the Company's Scope 1 (site emitted) and Scope 2 (off-site utility demand) emissions of CO<sub>2</sub>, less renewables and blending offsets, divided by refinery crude and lubricants and specialties feedstock. This metric is measured by actual performance during the 2024 calendar year versus target performance for the 2024 calendar year. For each of the Refining, Renewables, Lubricants & Specialties and Midstream segments, actual performance was 200.0%.

(7) For the Refining, Renewables and Lubricants & Specialties segments, the reliability metric is based on the sum of the weighted average Non-Turnaround Operational Unavailability Quarterly Target, with performance measured quarterly at each refinery or facility, as applicable. Management has discretion to apply a negative adjustment to the overall annual site payouts as a result of a high severity event or incident rate. For actual performance for the 2025 performance period, see the table below.

(8) Operating Expense includes all direct and controllable cash operating costs, which includes both operating costs and general and administrative (G&A) costs. Budgeted costs exclude asset write-downs, impairments, inventory valuation charges, unbudgeted litigation and legal settlement costs, environmental charges resulting from events which occurred prior to the beginning of the performance period, variable energy and utility costs, and unbudgeted bonus expenses and costs related to unbudgeted new capital assets brought online and acquisitions made during the period. The metric is based on the actual cash operating expense versus the budgeted cash operating expense for the Company. For the 2025 performance period, for each of the Refining, Renewables, Lubricants & Specialties and Midstream segments, actual performance was 125.2%, 200%, 190.9% and 200%, respectively.

(9) For the Midstream segment, in addition to the Greenhouse Gas Emissions reduction measure described above in footnote 6, the ESG metric is further divided into the following four equally weighted measures:

• Recordable Injury Rate, which is based on the number of employees out of 100 that have been involved in a recordable event. Actual performance for 2025 was 250.0%.

• Lost Time Injury, which is based on the number of injuries causing an employee to miss work. Actual performance for 2025 was 100.0%.

• Vehicle Incidents, which is based on the number of incidents generating greater than $5,000 of property damage per 1,000,000 miles driven by Midstream employees. Actual performance for 2025 was 154.7%.

• Employee Based Environmental Releases, which is based on loss of containment caused by an employee that is reportable to either a state or federal agency. Actual performance for 2025 was 167.0%.

(10) For the Midstream segment, the reliability metric is based on the weighted average Solomon Liquid Pipeline Availability. Actual performance for 2025 was 100.0%.

#### Financial Measures
The table below sets forth the threshold, target and maximum performance goals for each financial measure and the actual results for the financial measures in 2025:

#### Operational Measures
The table below sets forth the performance metrics that make up the operational measures, for our Refining, Renewables and Lubricants & Specialties segments, based on quarterly accruals at each of our geographic sites. If a site achieves three out of four of their pre-established fiscal quarterly targets, that operational category is multiplied by a 1.5x multiplier; if operational metrics are achieved in all four quarters, that operational category is multiplied by 2.0x for the Reliability metric and 2.5x for all other metrics. Actual results for each operational measure for our Refining, Renewables and Lubricants & Specialties segments, aggregated across all sites, as applicable, are reflected below for 2025:

#### Long-Term Equity Incentive Compensation.
The Compensation Committee typically grants equity-based awards during the fourth quarter of the year preceding the year to which the awards relate. We view long-term equity incentive compensation as the cornerstone of the executive compensation program because we believe:

• equity incentives and the related vesting periods help attract and retain executives capable of executing our business strategies;

• the value received by the recipient of equity incentives is aligned with long-term value creation for our stockholders; and

• equity incentives provide the closest link between our performance and the executives' compensation.

In determining the appropriate amount and type of long-term equity incentive awards to be made, the Compensation Committee considers a named executive officer's position, scope of responsibility, base salary, performance and market compensation information for executives in similar positions in similar companies and prior awards. In addition, the Compensation Committee has historically considered the recommendations of our Chief Executive Officer, except in regard to his own equity awards.

The Compensation Committee approves the grant of restricted stock unit awards and performance share unit awards to our named executive officers. Generally, annual grants of long-term equity incentive awards are made in the fourth quarter of the preceding year in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for our named executive officers and, with respect to performance share unit awards, to align the timing of the grant with the quarter in which the performance period commences. Pursuant to SEC rules, the long-term equity incentive awards granted in November 2024 for the 2025 fiscal year are disclosed as 2024 compensation in the Summary Compensation Table and are not included in the 2025 Grants of Plan-Based Awards table included in this proxy statement; however, because these awards relate to the 2025 fiscal year, they are described in greater detail below. The long-term equity incentive awards granted in November 2025 for the 2026 fiscal year are discussed below under *"—2026 Executive Compensation Decisions—Long-Term Equity Incentive Compensation for Named Executive Officers*."

#### Long-Term Equity Incentive Target Value
Annual grants of long-term equity incentive awards are initially approved by the Compensation Committee as a target dollar amount established according to the pay grade of the named executive officer and other factors, including scope of responsibilities, experience and individual performance. The award is then converted into a number of shares by dividing the dollar amount by the closing price of our common stock on the grant date of the award. For the awards granted in November 2024 for the 2025 fiscal year, the award for Mr. Go was allocated 65% to performance share units and 35% to restricted stock units; the awards to Mr. Atanasov and Mr. Nitcher were allocated 50% to performance share units and 50% to restricted stock units; and the awards to Mr. Ledbetter and Ms. Pompa were allocated 40% to performance share units and 60% to restricted stock units.

In addition to the annual grants of long-term equity incentive awards described above, the Company may grant long-term equity incentive awards as necessary to attract new executive talent. No such awards were granted in 2025.

The following table sets forth:

• the dollar value of the long-term equity incentive award granted for the 2025 fiscal year to each of the named executive officers; and

• the number of shares of restricted stock units with time-based vesting conditions and performance share units that were awarded for the 2025 fiscal year to each of the named executive officers.

---

#### Restricted Stock Unit Awards
The restricted stock unit awards granted to Messrs. Go, Atanasov, Ledbetter and Nitcher and Ms. Pompa in November 2024 for the 2025 fiscal year vest in three equal annual installments on December 1, 2025, 2026 and 2027 (or the first business day thereafter if the vesting date falls on a Saturday or Sunday), subject to their continued employment. For Messrs. Go, Atanasov, Ledbetter and Nitcher and Ms. Pompa, the first tranche of the restricted stock unit awards granted in November 2024 vested on December 1, 2025 and the remaining two tranches will vest on December 1, 2026 and 2027 (or the first business day thereafter if the vesting date falls on a Saturday or Sunday), subject to their continued employment.

Each named executive officer has the right to receive dividends and other distributions paid with respect to their restricted stock units, and these dividend and other distributions are paid at approximately the same time as dividends are received by our common stockholders.

#### Performance Share Unit Awards
The performance share unit awards granted to Messrs. Go, Atanasov, Ledbetter and Nitcher and Ms. Pompa in November 2024 for the 2025 fiscal year are subject to the achievement of return on capital employed and total shareholder return during the three-year performance period ending on September 30, 2027 relative to the 2025 "Incentive Peer Group." For 2025 (and 2024 and 2023), the Incentive Peer Group consisted of the following companies:

• CVR Energy, Inc.

• Delek US Holdings, Inc.

• Marathon Petroleum Corporation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• PBF Energy Inc.

• Phillips 66

• Valero Energy Corporation

We selected these companies because their collective performance is subject to the same external economic conditions we are facing as a company and as an industry as a whole. In addition, our management team and external investment analysts compare our results. The Incentive Peer Group differs from the 2025 compensation peer group because the Incentive Peer Group includes companies that are direct refining competitors that are too large in size or that significantly differ in ownership and management composition from us to be suitable comparisons for determining and establishing competitive pay data for our executives.

Each named executive officer has the right to receive dividend equivalents and other distributions with respect to their performance share units based on the target level of payout, and these dividend equivalents are paid at approximately the same time as dividends are received by our common stockholders.

For the performance share unit awards granted in November 2024 for the 2025 fiscal year:

• "return on capital employed," which determines 50% of the shares earned at the end of the performance period, is defined as operating income before depreciation and amortization (excluding inventory valuation gains or losses, asset impairments and non-cash asset write-downs) divided by capital employed at the beginning of the period, where capital employed means the sum of shareholders' equity plus minority interests plus debt, less goodwill and intangible assets less cash and marketable securities. The Compensation Committee believes return on capital employed is an appropriate metric because it (i) holds management accountable for the efficient use of the Company's capital and (ii) provides a useful means of comparing the Company's operating performance relative to the operating performance of our Incentive Peer Group. This metric looks at return on capital employed over a three-year period.

• "total shareholder return," which determines 50% of the shares earned at the end of the performance period, is defined as (i) the appreciation in our stock price during the performance period (in dollars) plus cumulative dividends paid during the performance period plus any additional value or compensation received by stockholders (such as stock received from spinoffs), divided by (ii) the closing price of our stock on the first business day of the performance period (which is adjusted to take into account any stock splits,

#### 2026 PROXY STATEMENT 49

------

##### [**Table of Contents**](#toc)

#### COMPENSATION DISCUSSION AND ANALYSIS
changes in capitalization or other similar events). The Compensation Committee believes total shareholder return is an appropriate metric because it (i) aligns the interests of management with the interests of stockholders, and (ii) provides a useful means of comparing the Company's overall performance relative to the overall performance of our Incentive Peer Group.

#### Performance Share Unit Performance Goals
The actual number of performance share units earned at the end of the performance period will be equal to (a) the target number of performance share units granted multiplied by (b) our average performance share unit payout with respect to the performance metrics. The average performance share unit payout is determined by adding our performance share unit payout percentage with respect to each performance metric and dividing the sum by two.

For the return on capital employed metric and the total shareholder return metric, a percentile ranking of our return on capital employed versus the return on capital employed of each entity in our Incentive Peer Group and our total shareholder return versus the total shareholder return of each entity in our Incentive Peer Group, respectively, will be calculated at the end of the performance period and payout is determined in accordance with the following table:

---

| | |
|:---|:---|
| &nbsp;&nbsp; Ranking of the Company within Incentive Peer Group | Performance Share Unit Payout |
| &nbsp;&nbsp; 90th Percentile or Above | Maximum (200% of Target) |
| &nbsp;&nbsp; Less than 90th Percentile but Above 50th Percentile | Interpolate between 100% and 200% |
| &nbsp;&nbsp; 50th Percentile | Target (100%) |
| &nbsp;&nbsp; Less than 50th Percentile but Above 25th Percentile | Interpolate between 25% and 100% |
| &nbsp;&nbsp; 25th Percentile | Threshold (25% of Target) |
| &nbsp;&nbsp; Less than 25th Percentile | Zero |

---

The named executive officer must be employed by us on December 1, 2027 (or the first business day thereafter if such date falls on a Saturday or Sunday) to receive payment of the earned performance share unit awards, except as described below in "*Executive Compensation—Potential Payments Upon Termination or Change in Control*." Earned performance share unit awards will be paid in the form of fully vested shares of our common stock.

#### Change in Control and Severance Benefits
Severance and change in control protections are provided to our named executive officers pursuant to (i) the terms of the applicable outstanding award agreements under the LTIP, (ii) change in control severance agreements and (iii) the HF Sinclair Corporation Severance Pay Plan (the "Severance Pay Plan"). The award agreements related to outstanding restricted stock units and performance share units granted to our named executive officers include accelerated vesting provisions in the event of certain terminations of employment, including in connection with a change in control.

We have entered into change in control severance agreements with each of our named executive officers. These agreements are designed to provide benefits only in the event of a qualifying termination of employment following a change in control transaction, and do not provide any benefits without a termination of employment. None of the change in control severance agreements we have with our named executive officers contain any tax reimbursement provisions in the event a named executive officer receives potential parachute payments under Section 280G of the Code.

In addition, the Compensation Committee adopted the Severance Pay Plan, pursuant to which all named executive officers and certain members of senior management or other executives of the Company, as designated by the Company, are eligible to receive the severance benefits provided for under the Severance Pay Plan. As of December 31, 2025, the Severance Pay Plan applied to all of our named executive officers. The Severance Pay Plan and change in control severance agreements contain certain provisions that are intended to avoid duplication of benefits under such arrangements in the event of overlapping qualifying terminations.

For additional information regarding change in control and severance benefits, see "*Executive Compensation—Potential Payments Upon Termination or Change in Control*."

#### COMPENSATION DISCUSSION AND ANALYSIS

#### Retirement Benefits and Perquisites

#### Retirement Plans
Defined Contribution Plan. For 2025, our named executive officers were able to participate in the HF Sinclair Corporation 401(k) Retirement Savings Plan, which is a tax-qualified defined contribution plan (the "401(k) Plan").

Employees may contribute amounts between 0% and 75% of their eligible compensation to the 401(k) Plan. Employee contributions that were made on a tax-deferred basis were generally limited to $23,500 for 2025, with employees 50 years of age or over able to make additional tax-deferred contributions of $7,500.

For 2025, we made a retirement contribution of 3% to 8% of the participating employee's eligible compensation under the 401(k) Plan, subject to applicable limitations under the Code, based on years of service, as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp; Years of Service | Retirement Contribution<br>(as percentage of eligible compensation) |
| &nbsp;&nbsp; Less than 5 years | 3% |
| &nbsp;&nbsp; 5 to 10 years | 4% |
| &nbsp;&nbsp; 10 to 15 years | 5.25% |
| &nbsp;&nbsp; 15 to 20 years | 6.5% |
| &nbsp;&nbsp; 20 years and over | 8% |

---

In addition to the retirement contribution, in 2025, we made matching contributions to the 401(k) Plan equal to 100% of the first 6% of each participating employee's eligible compensation up to compensation limits. In 2025, all of our named executive officers participated in the 401(k) Plan and received matching contributions and the retirement contribution. Matching contributions vest immediately and retirement contributions are subject to a three-year cliff-vesting period.

Deferred Compensation Plan. Certain of our employees, including our named executive officers, were also eligible to participate in the NQDC Plan in 2025. The NQDC Plan provides certain members of management and other highly compensated employees an opportunity to defer compensation in excess of qualified retirement plan limitations on a pre-tax basis and accumulate tax-deferred earnings to achieve their financial goals.

Participants in the NQDC Plan can contribute between 1% and 50% of their eligible earnings, which includes base salary and annual bonuses, to the NQDC Plan. Participants in the NQDC Plan are also eligible to receive certain employer-provided contributions, including, but not limited to, matching contributions, retirement contributions and nonqualified non-elective contributions. Matching contributions and retirement contributions represent contribution amounts that could not be made under the 401(k) Plan due to limitations on tax-qualified plans under the Code. We do not provide any subsidized returns or guarantee of returns on compensation deferred by our named executive officers or other participants in the NQDC Plan, nor do we require the participants to meet the 401(k) Plan contribution limits prior to deferring contributions into the NQDC Plan. For more information regarding this plan, see "*Executive Compensation—Nonqualified Deferred Compensation*."

#### Other Benefits and Perquisites
All of our executive officers are eligible to participate in the same benefit plans available generally to our salaried employees, such as medical, dental, vision, long-term and short-term disability and life insurance. We do not maintain separate "executive" plans for any of these benefits. We also make relocation benefits available to our salaried employees, including our named executive officers.

During 2025, Mr. Go, our Chief Executive Officer and President, was permitted to use the Company's aircraft for personal travel, subject to a requirement that he reimburse the Company for all fuel costs and taxes associated with such personal travel in accordance with our Personal Use of Company Aircraft Policy adopted on August 29, 2023 (the "Aircraft Policy"). Pursuant to the Aircraft Policy, the Company will cover up to $50,000 per calendar year of other direct costs, such as landing fees, catering charges, pilot overnight expenses and other similar charges incurred in connection with the Chief Executive Officer's personal travel. Any direct costs incurred by the Company as a result of the Chief Executive Officer's personal travel that exceed $50,000 in a calendar year will be invoiced to and must be promptly reimbursed by the Chief Executive Officer. In addition, we permit our Chief Executive Officer's family members to accompany the executive on a flight when the executive is traveling for business. No additional direct operating cost is incurred by us in such situations, but to the extent that Internal Revenue Service guidelines cause us to impute income to the Chief Executive Officer for such family member travel, and that travel is not business-related, the associated tax liability is the responsibility of the Chief Executive Officer.

#### 2026 PROXY STATEMENT 51

------

##### [**Table of Contents**](#toc)

#### COMPENSATION DISCUSSION AND ANALYSIS
During 2025, given the public profile of Mr. Go and publicity given to our industry, we provided reimbursement for certain home security services for Mr. Go, including alarm installation, maintenance and home security upgrades in accordance with the recommendations of an independent security assessment. We also provided reserved parking spaces for our executive officers.

We provide an annual perquisite allowance of $15,000 to each of our named executive officers which can be used at such executive's discretion. The Compensation Committee retains the discretion to provide additional monies or benefits above the perquisite allowance on a case-by-case basis. In addition, we may provide personal benefits to our executive officers in limited circumstances associated with executive team-building and strategy planning events.

#### Stock Ownership and Retention Policy
Our Board, the Compensation Committee and our executive officers recognize that ownership of our common stock is an effective means by which to align the interests of our officers with those of our stockholders. The terms of the stock ownership and retention policy for our officers are summarized below. The targeted multiples vary depending upon the officer's position and responsibilities, and our officers are required to meet the applicable requirements within five years of employment or promotion.

Under the stock ownership and retention policy, in 2025, our officers were required to hold shares of our common stock as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp; Company Officers | Value of Shares Owned |
| &nbsp;&nbsp; Chief Executive Officer | 6x base salary |
| &nbsp;&nbsp; Chief Financial Officer and General Counsel | 3x base salary |
| &nbsp;&nbsp; EVPs of Commercial and Operations (and other senior leadership) | 1x base salary |

---

The Compensation Committee reviews compliance with these guidelines annually. Shares of our common stock owned outright, outstanding restricted stock unit awards held by the individual and common stock held in the 401(k) Plan are counted when determining whether an officer has met the required ownership level. The officers are required to continuously own sufficient shares to meet the stock ownership requirements once attained. Until the officer attains compliance with the stock ownership policy, such officer is required to hold 50% of the shares of common stock received from any equity award, net of any shares used to pay tax withholdings. If an officer attains compliance with the stock ownership and retention policy and subsequently falls below the requirement because of a decrease in the price of our common stock, the officer will be deemed in compliance provided that the officer retains the shares then held.

As of December 31, 2025, all of our named executive officers were in compliance with the stock ownership and retention policy or were within the five-year transition period to become compliant.

#### Anti-Hedging and Anti-Pledging Policy
All of our employees, including our named executive officers, are subject to the Insider Trading Policy, which, among other things, prohibits employees from entering into short sales or hedging or pledging our securities.

The anti-hedging policy contained in our Insider Trading Policy specifically prohibits employees, including our named executive officers, and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Company securities (or derivatives thereof), including through, among other mechanisms, the purchase of financial instruments (such as prepaid variable forward contracts, equity swaps, collars, and exchange funds) or other transactions that are designed to hedge or offset any decrease in the market value of shares of our securities (or derivatives thereof). Additionally, all employees, including our named executive officers, are prohibited from holding our securities in a margin account or otherwise pledging our securities as collateral for a loan.

#### Recoupment of Compensation
In November 2023, in accordance with the implementing regulations of the Dodd-Frank Act and NYSE Listing Standards, the Board adopted a new mandatory clawback policy (the "Dodd-Frank Policy") and a revised discretionary clawback policy for certain acts of misconduct, which is located in the Company's employee handbook (the "Misconduct Policy" and, together with the Dodd-Frank Policy, the "Clawback Policies"). The Clawback Policies were effective as of December 1, 2023.

The Dodd-Frank Policy provides that, in the event the Company is required to prepare an accounting restatement of any of the Company's financial statements due to the Company's material noncompliance with any financial reporting requirement under U.S. securities laws, the Compensation Committee will seek to recoup all "recoverable" compensation, received on or after October 2, 2023, that is granted, earned or vested based wholly or in part upon the attainment of a financial reporting measure. "Recoverable" compensation is the amount of compensation that was granted, earned or vested during the last three completed fiscal years prior to the

52 ![LOGO](g71037g04a01.jpg)

------

##### [**Table of Contents**](#toc)

#### COMPENSATION DISCUSSION AND ANALYSIS
restatement based upon the financial reporting measure above what would have been received pursuant to the financial reporting measure had the financial statements in question been accurate. "Recoverable" compensation does not include base salaries, discretionary cash bonuses, awards (either cash or equity) that are based upon subjective, strategic or operational standards and equity awards that vest solely on the passage of time. The Dodd-Frank Policy applies to all current and former Section 16 officers, including our current named executive officers, and is a "no fault" policy, meaning that it may be triggered in the absence of fraud or willful misconduct by the executive.

The Misconduct Policy provides that, in the event of any Misconduct (as defined below) by any U.S.-based employee of the Company, including our named executive officers, at any point during the 12-month period preceding the date the Compensation Committee (for all Board-appointed executive officers) is notified of the event of Misconduct, the Compensation Committee may (as determined in its sole discretion and to the extent permitted by applicable law) cause the Company to (a) require such employee to repay any Incentive Compensation (as defined below) paid to the employee or that such employee was awarded or vested within the 24-month period prior to the date the Compensation Committee becomes aware of the Misconduct or at any time during or following the Misconduct, and/or (b) forfeit any Incentive Compensation owed to the employee, including cancelling any unvested, unearned or unsettled Incentive Compensation. "Incentive Compensation" includes any bonuses and other incentive and equity compensation (including those with time-based vesting conditions), in each case as determined in the sole discretion of the Compensation Committee.

Misconduct will be deemed to have occurred on the date that an employee engages in, intentionally or knowingly benefits from, or has supervisory authority over and knows of, or is willfully blind to, another's fraud, theft, willful misconduct, gross negligence, or any act or failure having a similar effect on the Company's reputation or performance or any act or omission that would result in recoupment under the Department of Justice's Compensation Incentives and Clawback Pilot Program. The determination of Misconduct will, for Board-appointed executive officers, be made by the Compensation Committee.

Further, our change in control severance agreements with our named executive officers provide that amounts paid or payable pursuant to such agreements may be forfeited and/or recouped to the extent required by applicable law or any clawback policy that we adopt.

In addition, the agreements for awards under our long-term equity incentive program provide that the award, including amounts paid or realized with respect to the award, may be subject to reduction, cancelation, forfeiture or recoupment to the extent required by applicable law or any clawback policy that we adopt.

#### Impact of Regulatory Compliance
In designing and implementing programs applicable to executives, the Compensation Committee considers the anticipated tax treatment to us and our executive officers of various payments and benefits, and the effects of applicable provisions of the Code, including Sections 280G and 162(m).

Section 280G of the Code prohibits the deduction of any "excess parachute payment." Benefits payable under the change in control severance agreements entered into with certain of our executives, including all of our named executive officers, as well as accelerated vesting under restricted stock unit and performance share unit award agreements could result in "excess parachute payments" that are not deductible by us. For more information regarding amounts payable and benefits available upon the occurrence of a change in control, see "*Executive Compensation—Potential Payments Upon Termination or Change in Control*." None of the change in control severance agreements we have with our named executive officers contain any tax reimbursement provisions in the event a named executive officer receives potential parachute payments under Section 280G of the Code.

#### Practices Related to the Grant of Certain Equity Awards in Relation to the Release of Material Nonpublic Information
We do not currently grant stock options or option-like equity awards to our employees or directors; therefore, we do not currently have a formal practice or policy with respect to the grant of stock options or option-like awards. During 2025, we did not time the disclosure of material nonpublic information to affect the value of other types of executive compensation awards granted to any service provider.

#### COMPENSATION DISCUSSION AND ANALYSIS
**2026 Executive Compensation Decisions** 

#### Annual Cash Incentive Compensation for Named Executive Officers
In the fourth quarter of 2025, the Compensation Committee approved target award levels as well as all other terms of the annual incentive cash compensation awards granted to our named executive officers for 2026. The Compensation Committee made the following enhancements to the annual incentive cash compensation program design for 2026:

• Thresholds and targets for the two components of the Financial metric, Available Free Cash Flow and AICP Adjusted EBITDA, were adjusted to align with the Company's projections and forecasts for the 2026 year.

• The ESG component of the Operational metric was rebalanced to place greater emphasis on operational and process safety measures, reflecting the Company's continued focus on the safety of its employees and contractors and preventing process safety events.

• Targets for Operational metrics, such as process safety, perfect environmental days and reliability, were updated for certain of the Company's business segments to further incentivize improved performance.

• The Operational metrics for the Midstream segment were revised to align them with the metrics used in the Company's other business segments.

The Compensation Committee made no other changes from the prior year to the annual incentive cash compensation program design for 2026 for the named executive officers. The 2026 annual incentive cash compensation awards will continue to be subject to a bonus hurdle that may limit the named executive officers' target bonus to 50% of the individual's target bonus if the Company does not achieve positive adjusted operating income (defined the same as within the 2025 program) for the 2026 fiscal year. The bonus hurdle is intended to align executive rewards with shareholder returns and reinforces our objective of paying for performance. The Compensation Committee will continue to retain full discretion to pay, not pay or modify all annual incentive cash compensation awards.

#### Long-Term Equity Incentive Compensation for Named Executive Officers
In November 2025, the Compensation Committee approved grants of restricted stock units with time-based vesting conditions and performance share units to our named executive officers for the 2026 fiscal year.

Pursuant to SEC rules, the long-term equity incentive awards granted in November 2025 for the 2026 fiscal year are disclosed as 2025 compensation in the Summary Compensation Table and are reported in the 2025 Grants of Plan-Based Awards table included in this proxy statement. These awards are described in greater detail below.

The following table sets forth:

• the dollar value of the long-term equity incentive award granted in 2025 for the 2026 fiscal year to each of the named executive officers; and

• the number of restricted stock units with time-based vesting conditions and performance share units that were awarded for the 2026 fiscal year to each of the named executive officers.

In November 2025, the Compensation Committee approved grants of restricted stock units with time-based vesting conditions to our named executive officers for the 2026 fiscal year. The restricted stock units awarded in November 2025 for the 2026 fiscal year will vest in three equal installments on December 1, 2026, 2027 and 2028 (or the first business day thereafter if December 1 falls on a Saturday or Sunday), subject to continued employment.

Each named executive officer that received an award has the right to receive dividend equivalents and other distributions paid with respect to such restricted stock units, and these dividend equivalents are paid at approximately the same time as dividends are received by our common stockholders.

#### Performance Share Unit Awards
In November 2025, the Compensation Committee granted performance share unit awards to our named executive officers for the 2026 fiscal year. The Compensation Committee determined that performance metrics for the November 2025 grants would consist of return on capital employed and total shareholder return during the performance period as measured against that of the 2026 Incentive Peer Group. The 2026 Incentive Peer Group consists of:

• CVR Energy Inc.

• Delek US Holdings, Inc.

• Marathon Petroleum Corporation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• PBF Energy Inc.

• Phillips 66

• Valero Energy Corporation

The performance period for these performance share unit awards runs from October 1, 2025 through September 30, 2028. Each named executive officer that received an award has the right to receive dividend equivalents and other distributions with respect to such performance share units based on the target level of payout, and these dividend equivalents are paid at approximately the same time as dividends are received by our common stockholders.

For the performance share unit awards granted in November 2025 for the 2026 fiscal year, "return on capital employed" and "total shareholder return" are calculated in the same manner as they are calculated for the performance share units granted in November 2024 for the 2025 fiscal year. The actual number of performance share units earned at the end of the performance period will be determined in the same manner as the performance share unit awards granted in November 2024 for the 2025 fiscal year.

For the return on capital employed metric and the total shareholder return metric, a percentile ranking of our return on capital employed versus the return on capital employed of each entity in our Incentive Peer Group and our total shareholder return versus the total shareholder return of each entity in our Incentive Peer Group, respectively, will be calculated at the end of the performance period and payout is determined in the same manner as the performance share unit awards granted in November 2024 for the 2025 fiscal year.

The named executive officer must be employed by us on December 1, 2028 (or the first business day thereafter if such date falls on a Saturday or Sunday) to receive payment of the earned performance share unit awards, except as described below in "*Executive Compensation—Potential Payments Upon Termination or Change in Control.*" Earned performance share unit awards will be paid in the form of fully vested shares of our common stock.

(1) As previously announced, on February 17, 2026, Mr. Go requested to take a voluntary leave of absence from his duties as Chief Executive Officer and President of the Company, and on February 24, 2026, Mr. Atanasov requested to take a voluntary leave of absence from his duties as Executive Vice President, Chief Financial Officer of the Company. Mr. Go and Mr. Atanasov remain on leave as of the date of this proxy statement.

(2) Represents base salary actually paid during the respective fiscal year. The reported salary amounts in any year may differ from the annual base salary amount reported due to the timing of payroll periods, the effective date of a change in base salary or may reflect partial year payments for years in which NEOs were not employed during the entirety of that year.

(3) Represents the aggregate grant date fair value of annual awards of restricted stock units and performance share units made in the year indicated, calculated in accordance with FASB ASC Topic 718, Compensation—Stock Compensation, excluding the effects of estimated forfeitures and does not reflect the actual value that may be ultimately realized by the executive. See Note 8 to our consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

Long-term equity incentive awards are granted in the year prior to the year to which they relate, therefore awards granted in November 2023 for the 2024 fiscal year are reported in the "Stock Awards" column of the Summary Compensation Table for 2023, long-term equity incentive awards granted in November 2024 for the 2025 fiscal year are reported in the "Stock Awards" column of the Summary Compensation Table for 2024, and long-term equity incentive awards granted in November 2025 for the 2026 fiscal year are reported in the "Stock Awards" column of the Summary Compensation Table for 2025, in each case, in accordance with SEC rules. <br>

For Mr. Go, the amount shown in the "Stock Awards" column for 2023 also includes a grant of 47,628 restricted stock units and 47,628 performance share units on the date of his promotion to Chief Executive Officer. <br>

For Mr. Ledbetter, the amount shown in the "Stock Awards" column for 2023 also includes a grant of 8,268 restricted stock units on the date of his appointment as Executive Vice President, Commercial. <br>

For Mr. Nitcher, the amount shown in the "Stock Awards" column for 2024 also includes a grant of 16,308 restricted stock units on the date of his appointment as Executive Vice President, General Counsel. <br>

The performance share units awarded in November 2025 to the named executive officers are subject to a "market condition" (the total shareholder return ("TSR") performance metric) and a "performance condition" (the return on capital employed ("ROCE") performance metric). For purposes of determining the grant date fair value of the performance share units granted in November 2025, in accordance with SEC rules and FASB ASC Topic 718, we have assumed an aggregate settlement of 99.65%, which includes a settlement of 49.65% of the TSR portion of the award and 50% of the ROCE portion of the award. The maximum payout of the aggregate awards, however, could be up to 200%. If the ROCE portion of the award was settled at the maximum payout level of 200% (resulting in settlement of the aggregate award in an amount equal <br>

to 149.65% for the November 2025 awards), the grant date fair value of the performance share unit awards would be as follows: Mr. Go, $9,727,261; Mr. Atanasov, $1,983,031; Mr. Nitcher, $1,309,641; Ms. Pompa, $957,843; and Mr. Ledbetter, $778,258.

#### EXECUTIVE COMPENSATION
**2025 Grants of Plan-Based Awards** 

The following table provides information about plan-based awards granted to our named executive officers under our equity and non-equity incentive plans during 2025. Certain equity awards reported below were granted in November 2025 for the 2026 fiscal year and are reported in this table as 2025 compensation in accordance with SEC rules. These awards are described in greater detail above under "*Compensation Discussion and Analysis—2026 Executive Compensation Decisions*." Annual equity awards are generally made once each year in the fourth quarter of the year preceding the year to which the annual awards relate in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for our executive officers. In accordance with SEC rules, the equity awards granted in November 2024 for the 2025 fiscal year were previously reported as 2024 compensation in the Grants of Plan-Based Awards table contained in our proxy statement filed with the SEC on April 1, 2025.

In this table, awards are abbreviated as "AICP" for awards under the annual incentive cash compensation program, "RSU" for restricted stock unit awards and "PUA" for performance share unit awards. The restricted stock unit awards and performance share unit awards granted to our named executive officers were granted under the HF Sinclair Corporation Amended and Restated 2020 Long Term Incentive Plan (as amended, the "LTIP").

(1) Represents the potential payouts for awards granted under our annual incentive cash compensation program, which were subject to achieving certain performance targets with respect to financial and operational measures, as applicable. Amounts reported (a) in the "Threshold" column reflect 50% of the named executive officer's target award opportunity under the annual incentive cash compensation program, which, in accordance with SEC rules, is the minimum amount payable for a certain level of performance under the award, (b) in the "Target" column reflect 100% of the named executive officer's target award opportunity under the annual incentive cash compensation program, which is the target amount payable under the award, and (c) in the "Maximum" column reflect 200% of the named executive officer's target award opportunity under the annual incentive cash compensation program, which is the maximum amount payable under the award. If less than minimum levels of performance, as described in the "Threshold" column, are attained with respect to the financial and operational measures, as applicable, under the annual incentive cash compensation program, then 0% of the named executive officer's target award opportunity will be earned.

The performance targets and target awards are described under "*Compensation Discussion and Analysis—2025 Executive Compensation Decisions—Annual Incentive Cash Compensation.*" Amounts actually paid with respect to the awards reported in this table are reported in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table for 2025. <br>

(2) Represents the potential number of performance share units payable under the LTIP. Amounts reported (a) in the "Threshold" column reflect 50% of the target number of performance share units awarded to each named executive officer, which, in accordance with SEC rules, is the minimum amount payable for a certain level of performance under the performance share unit awards, (b) in the "Target" column reflect 100% of the target number of performance share units awarded to each named executive officer, which is the target amount payable under the performance share unit awards, and (c) in the "Maximum" column reflect 200% of the target number of performance share units awarded to each named executive officer, which is the maximum amount payable under the performance share unit awards. If less than minimum levels of performance, as described in the "Threshold" column, are attained with respect to the return on capital employed and total shareholder return performance metrics applicable to the performance share unit awards, then 0% of the target number of performance share units awarded will be earned.

The number of shares actually delivered at the end of the performance period may vary from the target number of performance share units, based on our achievement of the specific performance measures. Performance targets and target awards for the awards reported above are described under "*Compensation Discussion and Analysis—2026 Executive Compensation Decisions—Long-Term Equity Incentive Compensation for Named Executive Officers.*" <br>

(3) Represents shares of restricted stock units subject to time-based vesting conditions granted under the LTIP. The terms of these grants are described under "*Compensation Discussion and Analysis—2026 Executive Compensation Decisions—Long-Term Equity Incentive Compensation for Named Executive Officers.* "

(4) Represents the grant date fair value of the restricted stock unit and performance share unit awards to our named executive officers. The grant date fair value was determined pursuant to FASB ASC Topic 718, based on the closing price of our common stock on the applicable grant date. The closing price of our common stock on November 11, 2025 was $55.02. With respect to the performance share units, amounts reflect an aggregate probable settlement percentage of 99.65% for the November 2025 grants.

**Outstanding Equity Awards at Fiscal Year End** 

The following table provides the number and value of outstanding equity awards held by our named executive officers as of December 31, 2025, including awards that were granted prior to 2025. All awards were granted pursuant to our LTIP. The value of our awards was calculated based on a price of $46.08 per share, the closing price of our common stock on December 31, 2025 (the last trading day of 2025).

The number and value of performance share units reported is based on the number of shares payable at the end of the performance period assuming the maximum level of performance is achieved.

**Option Exercises and Stock Vested** 

The following table provides information about the vesting in 2025 of restricted stock unit and performance share unit awards held by the named executive officers. The Company does not grant options.

The value realized from the vesting of restricted stock unit or performance share unit awards is equal to the closing price of our common stock on the vesting date (or, if the vesting date is not a trading day, on the trading day immediately following the vesting date), multiplied by the number of shares acquired on vesting. The value is calculated before payment of any applicable withholding or other income taxes.

**Pension Benefits** 

None of our named executive officers participates in or has ever participated in any plan sponsored or maintained by us that provides for specified retirement payments or benefits, such as a tax-qualified defined benefit plan or supplemental executive retirement plan.

**Nonqualified Deferred Compensation** 

In 2025, all of the named executive officers participated in the NQDC Plan. The NQDC Plan is a nonqualified plan (*i.e.*, not tax-qualified under Section 401 of the Code) that, in 2025, functioned as a pour-over plan, allowing key employees to defer tax on income in excess of limits under the Code that apply under the 401(k) Plan. For 2025, the annual deferral contribution limit under the 401(k) Plan was $23,500, and the annual compensation limit was $350,000. Deferral elections made by eligible employees under the NQDC Plan apply to the total amount of eligible earnings the eligible employees choose to contribute to both the 401(k) Plan and the NQDC Plan. Participants in the NQDC Plan are entitled to make independent deferral elections to the NQDC Plan and the 401(k) Plan prior to meeting the contribution limitations under the 401(k) Plan. Federal and state income taxes are generally not payable on income deferred under the NQDC Plan until funds are withdrawn.

Eligible executives may make salary deferral contributions between 1% and 50% of their eligible earnings to the NQDC Plan. Eligible earnings include base pay, bonuses and overtime, but exclude extraordinary pay such as severance, accrued vacation, equity compensation and certain other items. Eligible participants are required to make catch-up contributions to the 401(k) Plan before any contributions are made to the NQDC Plan. For 2025, the catch-up contribution limit was $7,500. Deferral elections are irrevocable for an entire plan year and must be made prior to December 31 immediately preceding the plan year. Elections will carry over to the next plan year unless changed or otherwise revoked.

#### 2026 PROXY STATEMENT 61

#### EXECUTIVE COMPENSATION
Participants in the NQDC Plan are eligible to receive a matching contribution with respect to their elective deferrals made up to 6% of the participant's eligible earnings for the plan year in excess of the limits under Section 401(k) of the Code. These matching contributions are 100% vested at all times. In addition, participants are eligible for a retirement contribution ranging from 3% to 8% of the participant's eligible earnings for the plan year in excess of the limits under Section 401(k) of the Code, based on years of service, as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp; Years of Service | Retirement Contribution<br>(as percentage of eligible compensation) |
| &nbsp;&nbsp; Less than 5 years | 3.00% |
| &nbsp;&nbsp; 5 to 10 years | 4.00% |
| &nbsp;&nbsp; 10 to 15 years | 5.25% |
| &nbsp;&nbsp; 15 to 20 years | 6.50% |
| &nbsp;&nbsp; 20 years and over | 8.00% |

---

These retirement contributions are subject to a three-year cliff vesting period and will become fully vested in the event of the participant's death or a change in control. Participants may also receive nonqualified non-elective contributions under the NQDC Plan, which contributions may be subject to a vesting schedule determined at the time the contributions are made.

Participating employees have full discretion over how their contributions to the NQDC Plan are invested among the offered investment options, and earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. We do not subsidize a participant's earnings under the NQDC Plan. During 2025, the investment options offered under the NQDC Plan were the same as the investment options available to participants in the 401(k) Plan, except as follows:

• the 401(k) Plan offers the T Rowe Price Retirement Date 2065 Fund, Principal Stable Value Z Fund, Principal Self-Directed Brokerage Account and stock of HF Sinclair; and

• the NQDC Plan instead offers the Vanguard Federal Money Market Investor Fund.

Benefits under the NQDC Plan may be distributed upon the earliest to occur of a separation from service (subject to a six-month payment delay for certain specified employees under Section 409A of the Code), the participant's death, a change in control or a specified date selected by the participant in accordance with the terms of the NQDC Plan.

#### EXECUTIVE COMPENSATION
**Potential Payments Upon Termination or Change in Control** 

We have agreements with our named executive officers that provide for severance compensation or accelerated vesting in the event of certain terminations of employment, including in connection with a change in control, which are summarized below. None of the agreements we have with our named executive officers contain any tax reimbursement provisions in the event a named executive officer receives potential parachute payments under Section 280G of the Code.

#### Change in Control Severance Agreements
We have entered into change in control severance agreements with each of our named executive officers. The term of these change in control agreements is generally three years from the date the change in control agreement is entered into, but the term of the agreement will be automatically extended for an additional two-year period beginning on the second anniversary of the date of the change in control agreement and any anniversary thereafter, unless a cancellation notice is given by us 60 days prior to the applicable expiration date.

#### Change in Control Severance Agreements for NEOs
Under the change in control agreements, a named executive officer is not entitled to receive payments or other benefits under the agreement unless there is a change in control and the named executive officer's employment is either terminated by us without cause, by the named executive officer for good reason, or as a condition to the consummation of the transaction constituting the change in control, in each case during the six months preceding the change in control or within two years following the change in control. If the named executive officer incurs a qualifying termination in connection with a change in control, the named executive officer will be entitled to:

• an amount equal to a multiple (the "severance multiplier") of (a) the greater of the officer's annual base salary on the date of termination or the date immediately prior to the change in control, plus (b) the officer's annual bonus amount, calculated as the average annual bonus paid to the officer for the prior three years. For 2025, the severance multiplier was 3.0x for Mr. Go and 2.0x for Messrs. Atanasov, Ledbetter and Nitcher and Ms. Pompa;

• a cash payment equal to unpaid base salary and reimbursement of expenses incurred by the officer prior to termination in connection with the business of the Company and accrued vacation pay;

• continued participation by the officer and his or her dependents in our medical and dental benefit plans for a period of one year following the later of the date of termination or the date of the change in control; and

• unless the applicable award agreement provides otherwise, all outstanding equity-based compensation awards shall become immediately vested at target level.

Definitions. The following definitions are used in the change in control severance agreements.

Under the change in control severance agreements, a "change in control" generally occurs if:

• a person or group of persons becomes the beneficial owner of more than 40% of the combined voting power of our then outstanding securities or more than 40% of our outstanding common stock;

• a majority of our Board is replaced during a 12-month period by directors who were not endorsed by a majority of the previous board members;

• the consummation of a merger, consolidation or recapitalization of us or one of our subsidiaries resulting in our stockholders prior to the merger owning less than 60% of the voting power of the new merged company or a recapitalization where no one owns more than 60% of the voting power; or

• our stockholders approve a plan of complete liquidation or dissolution or an agreement for the sale or disposition of all or substantially all of our assets.

Under the change in control severance agreements, "cause" is generally defined as:

• the engagement in any act of willful gross negligence or willful misconduct on a matter that is not inconsequential; or

• the conviction of a felony provided the conviction is damaging to the Company or to the public's perception of the Company;

in each case, as reasonably determined by the Board in good faith.

Under the change in control severance agreements, "good reason" is generally defined as, without the written consent of the executive, any of the following:

• a material reduction in the executive's (or his or her supervisor's) authority, duties or responsibilities;

64 ![LOGO](g71037g04a01.jpg)

------

##### [**Table of Contents**](#toc)

#### EXECUTIVE COMPENSATION
• a reduction in the executive's base compensation;

• the relocation of the executive to an office or location more than 50 miles from the location at which the executive normally performed the executive's services, except for travel reasonably required in the performance of the executive's responsibilities;

• if applicable, a failure of the executive to be appointed or re-elected as an officer or to the board of directors;

• a material diminution in the budget or other spending over which the executive has authority; or

• a material breach of the terms of the change in control severance agreement.

The named executive officer must provide notice to us of the alleged good reason event within 90 days of its occurrence and we have 30 days to cure following receipt of the notice.

Obligations of the Officer. Payments and benefits under the change in control agreements are conditioned on the execution of a general release of claims by the named executive officer in favor of us and our related entities and agents. In addition, the change in control agreements contain confidentiality provisions pursuant to which each named executive officer agrees not to disclose or otherwise use our confidential information, other than in the course of carrying out the executive's duties and responsibilities, during his or her employment with us and thereafter, as well as non-disparagement and non-solicitation covenants. Violation of these provisions entitles us to complete relief, including injunctive relief, and may result in the executive being terminated for cause (provided the breach constituted willful gross negligence or misconduct on the executive's part that is not inconsequential). The agreements do not prohibit the waiver of a breach of these covenants.

#### Long-Term Equity Incentive Awards
Special Involuntary Termination. The outstanding long-term equity incentive awards we granted in and after November 2022 under the LTIP vest immediately upon a "special involuntary termination," which means that, within 60 days prior to, or at any time after, a change in control (or, in the case of a sale of a division, within 90 days after such sale):

• the named executive officer is terminated by us, other than for cause; or

• the named executive officer resigns within 90 days after an adverse change has occurred.

For a "special involuntary termination" with respect to a sale of a division, more than 50% of the executive's full-time service to the Company must be attributable to services to the division being sold (as determined by the Company in its sole discretion).

Under the long-term equity incentive award agreements, a "change in control" generally occurs if:

• a person or group of persons becomes the beneficial owner of more than 40% of the combined voting power of our then outstanding securities;

• a majority of our Board is replaced by directors who were not endorsed by two-thirds of our prior board members;

• the consummation of a merger or consolidation of us or any of our subsidiaries other than (a) a merger or consolidation resulting in our voting securities outstanding immediately prior to the transaction continuing to represent at least 60% of the combined voting power of our voting securities or the voting securities of the surviving entity outstanding immediately after the transaction or (b) a merger or consolidation effected to implement a recapitalization of us in which no person or group becomes the beneficial owner of our securities representing more than 40% of the combined voting power of our then outstanding securities; or

• our stockholders approve a plan of complete liquidation or dissolution or an agreement for the sale or disposition of all or substantially all of our assets.

Under the long-term equity incentive award agreements, "cause" is generally defined as:

• an act of dishonesty constituting a felony or serious misdemeanor and resulting (or intended to result) in personal gain or enrichment to the recipient at our expense;

• gross or willful and wanton negligence in the performance of the recipient's material and substantial duties; or

• conviction of a felony involving moral turpitude;

in each case, as determined by the Compensation Committee in its sole discretion.

Under the long-term equity incentive award agreements, an "adverse change" generally means, without the consent of the recipient:

• a change in the geographic location at which the recipient is required to work regularly;

• a substantial increase in travel requirements of employment;

#### 2026 PROXY STATEMENT 65

------

##### [**Table of Contents**](#toc)

#### EXECUTIVE COMPENSATION
• a substantial reduction in the duties previously performed by the recipient; or

• a significant reduction in the recipient's base compensation (other than bonuses and other forms of discretionary compensation, or a general reduction applicable generally to executives).

Under the long-term equity incentive award agreements, "division" generally means:

• each of the refining, midstream or lubricants & specialties segments of the Company; or

• any other segment or significant line of business identified by the Compensation Committee as a "division."

Under the long-term equity incentive award agreements, the "sale of a division" generally means:

• a sale or disposition of a substantial portion of a division (other than a sale or disposition to the Company or any of its subsidiaries); or

• any other transaction resulting in loss of control by the Company and its subsidiaries over a substantial portion of a division (including a public offering of a division where the Company does not control the division following the offering);

in each case, as determined by the Compensation Committee in its sole discretion.

Performance Share Units upon Termination. In the event of a voluntary separation or termination by the Company with or without cause, the recipient will forfeit any outstanding performance share units.

In the event of death or disability, the recipient becomes vested in a number of performance share units equal to the percentage of time the recipient was employed during the vesting period multiplied by the target number of performance share units awarded. Under all of the performance share units, if the recipient dies or is disabled, the Compensation Committee, in its sole discretion, may determine the performance percentage in an amount up to 200%.

If the executive's employment with the Company or its subsidiaries terminates prior to December 1 of Year Three (as defined in the applicable agreement) as a result a special involuntary termination, the performance share units will immediately vest assuming a performance unit payout percentage of 100% of target instead of the performance unit payout percentage that would otherwise be determined at the end of the performance period.

If the recipient retires before the end of the performance period, the recipient becomes vested in a number of performance share units equal to the percentage of time the recipient was employed during the vesting period multiplied by the target number of performance share units awarded. "Retirement" for purposes of the performance share units means termination of employment other than for cause on or after the date on which the recipient has achieved ten years of continuous service with the Company and is age 60.

Restricted Stock Units upon Termination. In the event of a voluntary separation or termination by the Company with or without cause, the recipient will forfeit the unvested portion of the restricted stock units award.

In the event of death or disability, the recipient becomes vested in a number of shares of restricted stock units equal to the percentage of time the recipient was employed during the vesting period multiplied by the total number of shares of restricted stock units the recipient was awarded. The Compensation Committee may decide to vest all of the shares of restricted stock units.

If the recipient retires before the full vesting of restricted stock unit awards, the recipient becomes vested in a number of restricted stock units equal to the percentage of time the recipient was employed during the vesting period multiplied by the total number of shares of restricted stock units the recipient was awarded. Retirement for purposes of the restricted stock units is defined in the same manner as for the performance share units.

Restrictive Covenants. The long-term equity incentive awards granted to our named executive officers contain certain restrictive covenants that generally mirror the release requirements and confidentiality restrictions found in our change in control agreements described above. The awards were also granted with non-solicitation provisions that generally prevent the named executive officers from soliciting any employee or service provider of us or our subsidiaries for one year following a termination of employment. The long-term incentive awards were also granted with non-disparagement restrictions that obligate the named executive officers to refrain from making disparaging, negative or otherwise detrimental comments concerning us, any of our subsidiaries or our directors, officers, managers, employees, equityholders, members or partners and non-competition provisions that generally prevent the named executive officers from owning, managing, operating or serving as an officer or director of, or joining, becoming an employee or consultant of, or otherwise being affiliated with, any person or entity engaged in, a business that competes with us or any of our subsidiaries within a defined market area for a period of one year following termination of employment. In the event of a breach of any of the foregoing restrictive covenants by an award recipient, the unvested portion of the recipient's awards will be immediately forfeited.

#### EXECUTIVE COMPENSATION

#### Severance Pay Plan
In November 2022, the Compensation Committee adopted the Severance Pay Plan pursuant to which executive officers and members of senior management of the Company, as designated by the Company, will be eligible to receive the severance benefits provided for under the Severance Pay Plan, pursuant to the terms and conditions of the Severance Pay Plan and the individual participation agreements which will specify the terms and conditions for each eligible participant and shall govern to the extent such terms vary from the Severance Pay Plan. As of December 31, 2025, all of our named executive officers were participants in the Severance Pay Plan. The Severance Pay Plan solely addresses potential cash severance payments and benefit continuation coverage, therefore there is no impact to the treatment of outstanding equity awards pursuant to the Severance Pay Plan.

Unless otherwise specified in an individual participation agreement, upon a termination without Cause (as defined below) by the Company, the participant will be eligible to receive the following benefits:

• a cash payment, payable in 12 monthly installments, equal to a percentage of such participant's annual base salary, plus the amount of bonus, if applicable, that would have been paid under the annual cash incentive compensation program (paid as if the Company had achieved target level of performance for the year of the participant's termination); and

• continuation coverage for the individual and his or her eligible dependents under our group health plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), for twelve months at active employee rates, unless such coverage is earlier terminated in accordance with the terms of the Severance Pay Plan.

The applicable percentage of annual base salary and bonus (if any) will be determined based on the officer's pay grade classification:

---

| | |
|:---|:---|
| &nbsp;&nbsp; CEO | 200% base salary + 100% target bonus |
| &nbsp;&nbsp; Other NEOs | 100% base salary + 100% target bonus |
| &nbsp;&nbsp; Certain Management-Level Employees | 100% base salary |

---

Pursuant to the Severance Pay Plan, a termination for "Cause" means (a) an act or acts of dishonesty by a participant constituting a felony or serious misdemeanor and resulting or intended to result directly in gain or personal enrichment at the expense of the Company or any subsidiary; (b) gross or willful and wanton negligence in the performance of a participant's material and substantial duties of employment with the Company and its subsidiaries; or (c) a participant's conviction of a felony involving moral turpitude. The existence of Cause shall be determined by the Company, in its sole and absolute discretion.

#### Quantification of Benefits
The following table summarizes the compensation and other benefits that would have become payable to each named executive officer, assuming his or her employment terminated on December 31, 2025, including a termination in connection with a change in control, given the named executive officer's base salary as of that date, and, if applicable, the closing price of our common stock on December 31, 2025 (the last trading day of 2025), which was $46.08.

In reviewing these tables, please note the following:

• Accrued vacation for a specific year is not allowed to be carried over to a subsequent year, so we assumed all accrued vacation for the 2025 fiscal year was taken prior to December 31, 2025. Because we accrue vacation in any given year for the following year, amounts reported as "Cash Severance" include the vacation amounts accrued in 2025 for the 2026 fiscal year.

• The row entitled "Performance Share Units" reports amounts payable with respect to outstanding performance share unit awards issued by us. For amounts payable to the named executive officers with respect to performance share unit awards, we assumed the outstanding performance share units would settle at target (100% of the original grant date number of awards) under the column entitled "Change in Control and Involuntary Termination Without Cause or Voluntary Departure for Good Reason or a Special Involuntary Termination," and under the column entitled "Death or Disability," we have reflected accelerated vesting based on the length of employment during the applicable vesting period for each award. For additional information regarding the potential payouts, see "*Compensation Discussion and Analysis—2026 Executive Compensation Decisions—Long-Term Equity Incentive Compensation for Named Executive Officers—Performance Share Unit Awards*," "*Executive Compensation—2025 Grants of Plan-Based Awards"* and *"Executive Compensation—Outstanding Equity Awards at Fiscal Year End*."

• For the amounts shown in the row entitled "Restricted Stock Units" under the column entitled "Death or Disability," we have reflected accelerated vesting based on the length of employment during the applicable vesting period for each award.

• The amounts shown in the row entitled "Medical and Dental Benefits" represent amounts equal to the monthly premium payable pursuant to COBRA, for medical and dental premiums, multiplied by 12 months for each of the named executive officers. Mr. Nitcher and Ms. Pompa did not participate in our medical plans during the 2025 year, therefore their amounts are deemed to be $0.

#### EXECUTIVE COMPENSATION
**Compensation Practices and Risk Management** 

Certain members of our management annually review the relationship between our risk assessment guidelines and our compensation programs. In addition, certain members of our management and the Compensation Committee annually review the features and characteristics of our compensation programs, including particular areas that could encourage employees to take excessive risk or focus on short-term results at the expense of long-term value creation, to confirm that our compensation programs do not encourage excessive and unnecessary risk taking. As part of this review, the Compensation Committee and certain members of management review salaries, annual incentive bonus awards, including the targets established for the annual incentive bonus awards, and long-term equity incentive awards, including the performance measures used for a portion of the long-term equity incentive awards, at all levels of the Company.

Although the majority of the compensation provided to the named executive officers is performance-based, we believe our compensation programs do not encourage excessive or unnecessary risk-taking by executive officers (or other employees) because these programs are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals. In addition, we explicitly include Company safety, health and environmental performance in determining potential payouts under our annual incentive cash plan for senior executives.

While annual cash-based incentive bonus awards play an appropriate role in our executive compensation program, the Compensation Committee believes that basing payment determinations on an evaluation of our performance across a variety of measures mitigates excessive risk-taking that could produce unsustainable gains in one area of performance at the expense of our overall long-term interests. In addition, performance goals reflect our past performance and market conditions affecting our industry.

An appropriate part of total compensation is fixed for the named executive officers, while another portion is variable and linked to performance. A portion of the variable compensation we provide is comprised of long-term incentives. A portion of the long-term incentives consists of restricted stock units subject to time-based vesting conditions, which retain value even in a depressed market, so executives are less likely to take unreasonable risks. With respect to our performance share unit awards, assuming achievement of at least a minimum level of performance, payouts result in some compensation at levels below full target achievement, in lieu of an "all or nothing" approach.

As discussed above, while a portion of our potential annual compensation is incentive based, we have also instituted policies and programs designed to discourage unnecessary risk-taking, which is not in our long-term interests. For example, our stock ownership policy requires executives to hold at least a specified level of stock (in addition to any unsettled performance-based equity awards), which aligns our executives' interests with those of our long-term stockholders. Also, our Clawback Policies allow for recoupment of annual and long-term incentive compensation upon the occurrence of an accounting restatement resulting from material noncompliance with any financial reporting requirement under U.S. securities laws or upon certain acts of misconduct.

Based on the foregoing and our annual review of our compensation programs, we do not believe that our compensation policies and practices are reasonably likely to have a material adverse effect on the Company or our stockholders.

**CEO Pay Ratio** 

As required by Section 953(b) of the Dodd-Frank Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of annual total compensation of our employees and the annual total compensation of Mr. Go, our Chief Executive Officer and President for fiscal year 2025. We used the same median employee identified in 2024 for the pay ratio calculation for 2025. There has been no change in our employee population or employee compensation that we reasonably believe would result in a significant change in the pay ratio disclosure.

To determine the annual total compensation of our median employee, we examined the taxable wages for all U.S. and Canadian employees, whether employed on a full-time, part-time, temporary or seasonal basis, who were employed by us on December 20, 2024. The pay ratio disclosure rules provide an exemption for companies to exclude non-U.S. employees from the median employee calculation if non-U.S. employees in a particular jurisdiction account for 5% or less of the company's total number of employees. Given the geographical distribution of our employee population, we applied this de minimis exemption when identifying the median employee by excluding certain employees located in Germany (5), the Netherlands (196) and the U.K. (7). We did not make any assumptions, adjustments or estimates with respect to the taxable wages other than deducting stock vesting from the taxable wages, and we did not annualize the wages for any employees that were not employed by us for all of 2025. We believe the use of taxable wages is the most appropriate compensation measure since it allows for a consistent measurement for employees in different countries.

After identifying the median employee based on total taxable wages, we combined all of the elements of such employee's compensation for the 2025 year in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K. The median employee's annual total compensation was as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| &nbsp;&nbsp; Name | Year | Salary | Stock<br>Awards | Non-Equity<br>Incentive Plan<br>Compensation | All Other<br>Compensation | Total |
| &nbsp;&nbsp; Median Employee | 2025 | $131964 |  | $22039 | $19913 | $173916 |

---

For 2025, Mr. Go had a total annual compensation of $14,278,553, as reflected in the Summary Compensation Table. Our 2025 ratio of Chief Executive Officer total compensation to the median employee's total compensation is 82:1. The SEC's pay ratio disclosure rules permit the use of estimates, assumptions and adjustments. We believe that the foregoing pay ratio is a reasonable estimate calculated in a manner consistent with the SEC's pay ratio disclosure rules.

(1) The Summary Compensation Table Total for Principal Executive Officer ("PEO") and Compensation Actually Paid to PEO include the following PEOs for each year shown:

• 2025 and 2024: Timothy Go .

• 2023: Mr. Go (top row), who was promoted to the position of Chief Executive Officer and President, effective May 9, 2023, and Michael C. Jennings , who transitioned to the position of Executive Vice President, Corporate, from May 9, 2023 until his retirement from the Company on November 9, 2023.

• 2022 and 2021: Mr. Jennings .

(2) The non-PEO NEOs are as follows:

• 2025: Atanas H. Atanasov, Eric L. Nitcher, Valerie Pompa and Steven C. Ledbetter.

• 2024: Mr. Atanasov, Mr. Nitcher, Ms. Pompa and Mr. Ledbetter.

• 2023: Mr. Atanasov, Vaishali S. Bhatia (former Executive Vice President, General Counsel and Secretary), Ms. Pompa and Mr. Ledbetter.

• 2022: Mr. Atanasov, Mr. Go, Ms. Bhatia, Richard L. Voliva III (former Executive Vice President and Chief Financial Officer) and Thomas G. Creery (former President, Renewables).

• 2021: Mr. Voliva III, Mr. Go, Mr. Creery and Ms. Bhatia.

(3) Cumulative TSR is measured as of a base period of December 31, 2020 and determined based on the value of an initial fixed investment of $100.

(4) The peer group used for relative TSR is the Incentive Peer Group, which is the same peer group the Company uses for its Item 201(e) of Regulation S-K each year reflected within this table.

(5) The Company-selected measure is AICP Adjusted EBITDA , which is a performance measure used in the calculation of our annual cash incentive awards. Calculation of AICP Adjusted EBITDA differs from the calculation of EBITDA as reported in our financial statements. See Appendix A for the specific adjustments and the reconciliation of AICP Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, for the periods presented.

The time period for the AICP Adjusted EBITDA disclosed in the table above differs from the actual AICP Adjusted EBITDA used in the calculation of the 2025, 2024, 2023, 2022 and 2021 annual incentive awards because the AICP Adjusted EBITDA disclosed in the table is calculated based on the fiscal year ended December 31, 2025, 2024, 2023, 2022 and 2021 to align with the period of the other compensation and financial measures reported in the table. The AICP Adjusted EBITDA actually used in the calculation of the annual incentive awards our named executive officers received is based on the actual annual incentive award performance period, which commences on October 1 of the previous year and runs through September 30 of the current year. Therefore, the AICP Adjusted EBITDA disclosed in the table is not the actual AICP Adjusted EBITDA that was used in the calculation of the annual incentive awards the named executive officers received for the periods presented. See "—2025 Executive Compensation Decisions" for further discussion of the Company's annual incentive cash compensation program and the 2025 performance period AICP Adjusted EBITDA used in the calculation of the 2025 annual incentive cash awards and see the similar discussions of previous year annual incentive cash compensation programs within the Company's 2025, 2024, 2023 and 2022 proxy statements with respect to the AICP Adjusted EBITDA values used in the calculation of the 2024, 2023, 2022 and 2021 annual incentive cash awards, respectively. <br>

#### Narrative to Pay Versus Performance Table
The Pay Versus Performance table above demonstrates the alignment between CAP to the named executive officers and the Company's performance, consistent with our compensation philosophy as described above in "Compensation Discussion and Analysis." Specifically, a large portion of the named executive officers' compensation is tied to TSR, and as such, the PEO and non-PEO NEO CAP each year aligned with our TSR performance and increased when our TSR performance increased but declined when our TSR performance declined. The charts below show, for the past five years, the relationship of the Company's TSR relative to its Incentive Peer Group, as well as the relationship between the PEO and non-PEO NEO CAP and the Company's TSR, net income and AICP Adjusted EBITDA.

## Equity Compensation Plan

## Information
We currently maintain one equity plan for the benefit of our employees, directors and consultants: the HF Sinclair Corporation Amended and Restated 2020 Long Term Incentive Plan (as amended, the "LTIP").

The following table sets forth information regarding the LTIP as of December 31, 2025.

| &nbsp;&nbsp; Equity compensation plans not approved by stockholders |  |  |  |
| &nbsp;&nbsp; Total | 2488532 |  | 2770539 |

---

(1) All stock-based compensation plans are described in Note 8 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

(2) As of December 31, 2025, there were 1,733,016 full-value awards outstanding, which includes 977,500 restricted stock unit awards outstanding and 755,516 performance share unit awards outstanding based on the target payout level at the time of vesting. The number of full-value awards outstanding reported in the table above assumes a maximum payout level for the performance share unit awards at the time of vesting, which results in 1,511,032 shares subject to performance share unit awards outstanding as of December 31, 2025 and a total of 2,488,532 full-value awards outstanding as of December 31, 2025 (which includes the 977,500 restricted stock unit awards outstanding as of December 31, 2025). There were no options outstanding under the LTIP as of December 31, 2025.

(3) This number is calculated assuming performance share unit awards granted to our key employees under the LTIP will be settled at the maximum payout level at the time of vesting. If the performance share unit awards are paid at the target payout level, 755,516 shares would be issued upon the vesting of such performance share unit awards and the number of shares available for issuance would increase to 3,520,055.

## Certain Relationships and Related

#### Related Person Transactions
Ross B. Matthews, a member of our Board, currently serves as the Chair of the Board of Directors of REH Advisors and members of his immediate family control REH, which received 60,230,036 shares of the Company's common stock, representing 26.98% of the Company's common stock as purchase consideration upon the closing of the Sinclair Transactions on March 14, 2022, and an additional 6,615,000 shares of common stock pursuant to the Holly Energy Partners, L.P. ("HEP") merger transaction, whereby HEP became a wholly-owned subsidiary of the Company on December 1, 2023. As of the Record Date, REH Advisors held 12,711,842 shares of the Company's common stock representing 7.05% of the Company's common stock.

During the year ended December 31, 2025, the Company repurchased 3,345,857 shares of the Company's common stock from REH Advisors in privately negotiated transactions.

Pursuant to the Stockholders Agreement, the Company and REH have ongoing indemnification obligations to each other as more specifically detailed in the Stockholders Agreement. Each party will indemnify the other for (i) any breach or inaccuracy of fundamental representations, and (ii) breach of or failure to perform any of its covenants or agreements contained in the Stockholders Agreement. The Company will also indemnify REH for its failure to pay or discharge an assumed liability when due. REH will also indemnify the Company for its failure to pay or discharge a retained liability when due, certain indebtedness and certain taxes.

Pursuant to the Stockholders Agreement, effective as of the closing of the Sinclair Transactions, the Company granted certain director nomination and registration rights to the REH Parties and the REH Parties agreed to certain lock-up, standstill and voting restrictions, each as summarized below:

• Director Designees: The REH Parties were entitled to designate for election or appointment, and did designate, (a) two persons to the Board at the closing of the Sinclair Transactions and for so long as the REH Parties beneficially owned common stock constituting not less than 15% of all outstanding shares of the Company's common stock and (b) one person to the Board for so long as the REH Parties beneficially own less than 15% but more than or equal to 5% of all outstanding shares of the Company's common stock. The REH Parties currently have the right to designate one person for election or appointment to the Board and Mr. Matthews currently serves as the REH Parties' appointee on the Board.

• Lock-up Restrictions *:* Until the earliest to occur of (i) the date on which the REH Parties beneficially own shares of the Company's common stock constituting less than 5% of all outstanding shares of the Company's common stock and (ii) the date on which a Change of Control (as defined in the Stockholders Agreement) occurs, the REH Parties will be prohibited from transferring the shares of the Company's common stock owned by them to certain prohibited transferees, subject to certain permitted exceptions.

• Registration Rights : The Company agreed to file, and has filed, a shelf registration statement to permit the public resale of all the registrable securities held by the REH Parties. The Company also agreed to support underwritten offerings of shares of the Company's common stock held by the REH Parties within the prescribed time periods outlined in the Stockholders Agreement.

• Voting Restrictions : The REH Parties have agreed to vote at any annual or special meeting of the stockholders all shares of the Company's common stock held by them (i) in accordance with the Board's recommendations in respect of stockholder proposals and certain proposals submitted by the Company, including the ratification of the Company's independent public accounting firm, "say-on-pay" votes, and proposals relating to an incentive compensation plan or a material amendment thereof, and (ii) with respect to each nominee for election to the Board, either (in their sole discretion) (A) in accordance with the Board's recommendation, or (B) in the same proportion as the votes cast by stockholders of the Company who are not REH Parties. The voting agreements continue until the date on which the REH Parties are no longer entitled to nominate a director to the Board.

During the year ended December 31, 2025:

• The Company paid an aggregate of approximately $0.2 million for its share of operating expenses under the Salt Lake City office lease between the Company and REH;

##### [**Table of Contents**](#toc)

#### CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
• The Company received an aggregate of approximately $35.4 million from REH for fuel sales to hospitality properties that operate fuel stations owned by REH pursuant to distributor sales contracts between a subsidiary of the Company and REH subsidiaries;

• The Company paid an aggregate of approximately $1.6 million to REH subsidiaries for business-related expenses, such as hotel stays, meals, fuel charges and conference services, at hospitality properties owned by REH subsidiaries;

All of the foregoing transactions with REH were approved by the Audit Committee of the Company.

#### Review, Approval or Ratification of Transactions with Related Persons
The Board adopted a written related party transaction policy to document procedures for the notification, review, approval, ratification and disclosure of related party transactions (the "Related Party Transaction Policy"). Under the Related Party Transaction Policy, a "related person" includes any director, director nominee, executive officer, or holder (together with any of its controlling or controlled affiliates) of more than 5% percent of our voting stock, an immediate family member of any of the foregoing persons or an entity that is owned or controlled by any of the foregoing persons, any of the foregoing persons have a substantial ownership interest or control, or an entity in which any of the foregoing persons is an executive officer or general partner, or holds a similar position. The Related Party Transaction Policy applies to any transaction, arrangement, or relationship or series of similar transactions, arrangements or relationships (including indebtedness or guarantee of indebtedness) in which (i) the aggregate amount involved will or may be expected to exceed $120,000 in any fiscal year, (ii) we or our subsidiaries are a participant, and (iii) a related person has a direct or indirect material interest.

Certain transactions, including compensation for services provided to a related person, such as an executive officer or director, are pre-approved under the Related Party Transaction Policy.

The Related Party Transaction Policy provides that the Audit Committee will be responsible for reviewing and approving related party transactions that may arise within our Company. The Audit Committee will review the material facts of all related party transactions that require the committee's approval and either approve or disapprove of the entry into the related party transaction. The Related Party Transaction Policy prohibits any director from participating in any discussion or approval of a related party transaction for which such director is a related person, except that such director is required to provide all material information concerning the interested transaction to the committee. Related party transactions required to be disclosed in our SEC reports are reported through our disclosure controls and procedures.

Prior to November 2025, our Code of Conduct governed conflicts of interests involving employees who are not covered by the Related Party Transaction Policy described above. Pursuant to the Code of Conduct, conflicts of interest were required to be disclosed to and reviewed by a supervisor who does not have a conflict of interest, the Human Resources Department or the Legal and Compliance Department, and approval must be obtained prior to proceeding with the potentially conflicted situation. In November 2025, the Board adopted a written conflicts of interest policy (the "COI Policy") to document procedures for identifying, disclosing and reviewing actual, perceived and potential conflicts of interest. Under the COI Policy, employees who have an actual or perceived conflict of interest are required to disclose such conflict whereby the Company's Chief Compliance Officer and the discloser's manager will review and analyze steps necessary to eliminate or mitigate the conflict of interest. Employees of the Company above a certain pay grade, including our named executive officers, must complete a mandatory annual conflict of interest disclosure form.

## Ratification of Appointment of Ernst &

## Young LLP (Proposal 3)
The Audit Committee has appointed Ernst & Young LLP, an independent registered public accounting firm, to be the Company's auditor for fiscal year 2026. The Board is asking stockholders to ratify this appointment. SEC regulations and the NYSE listing requirements require the Company's independent registered public accounting firm to be engaged, retained and supervised by the Audit Committee. However, the Board considers the selection of an independent registered public accounting firm to be an important matter to stockholders. Accordingly, the Board considers a proposal for stockholders to ratify this appointment to be an opportunity for stockholders to provide input to the Audit Committee and the Board on a key corporate governance issue. If the stockholders do not ratify the selection of Ernst & Young LLP, the Audit Committee will reconsider the selection of that firm as the Company's independent registered public accounting firm.

Ernst & Young LLP has conducted the Company's audits since 1977. We expect representatives of Ernst & Young LLP to be present at the Annual Meeting, with an opportunity to make a statement if they desire to do so, and to be available to respond to appropriate questions from our stockholders. For additional information regarding our independent registered public accounting firm, see "*Independent Public Accountants*."

**Required Vote and Recommendation** 

The ratification of the appointment of Ernst & Young LLP requires the approval of a majority of the votes cast on the proposal.

(3) Represents fees for professional services provided in connection with tax advisory, compliance and planning.

**Pre-Approval Policies and Procedures** 

The Audit Committee's policy is to pre-approve all audit services performed by the independent auditor to assure that performing such services does not impair the auditor's independence.

The Audit Committee may also pre-approve fees related to other non-recurring services. The Chairperson of the Audit Committee may approve certain services from time to time; however, any such decisions made must be reported to the Audit Committee at the next meeting of the Audit Committee.

## Audit Committee Report
The Company's management is responsible for preparing our financial statements and for our system of internal control over financial reporting. Ernst & Young LLP, our independent registered public accounting firm, is responsible for performing an independent audit of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB") and to issue a report thereon. The Audit Committee is responsible for overseeing management's conduct of the financial reporting process and system of internal control. The Audit Committee also is responsible for selecting, engaging and overseeing the work of the Company's independent registered public accounting firm, which reports directly to the Audit Committee, and evaluating its qualifications and performance. Among other things, to fulfill its responsibilities, the Audit Committee:

• reviewed and discussed with both management and Ernst & Young LLP the Company's quarterly unaudited consolidated financial statements and annual audited financial statements for the year ended December 31, 2025, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements, including those in management's discussion and analysis thereof;

• discussed with Ernst & Young LLP the matters required to be discussed by the applicable requirements of the PCAOB, the SEC and the NYSE;

• discussed with Ernst & Young LLP matters relating to its independence and received the written disclosures and letter from Ernst & Young LLP required by applicable requirements of PCAOB regarding the independent accountant's communications with the Audit Committee concerning the firm's independence;

• discussed with our internal auditors and Ernst & Young LLP the overall scope and plans for their respective audits and met with the internal auditors and Ernst & Young LLP, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls and the overall quality of our financial reporting; and

• considered whether Ernst & Young LLP's provision of non-audit services to the Company is compatible with the auditor's independence.

Taking all of these reviews and discussions into account, the Audit Committee recommended to the Board that the audited financial statements for the year ended December 31, 2025 be included in HF Sinclair Corporation's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for filing with the SEC.

## Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires the Company's directors, Section 16 officers and holders of more than 10% of its shares of common stock to file with the SEC initial reports of ownership of shares of common stock and reports of changes in such ownership. Based solely on a review of reports filed with the SEC, the Company believes that, during 2025, all Section 16(a) filing requirements applicable to its directors, Section 16 officers and greater than 10% stockholders were met, other than Mr. Go, for whom one late report was filed to correct an initial Form 4 that was timely filed but, due to an administrative error, inadvertently understated the amount of his long-term equity incentive awards granted in November 2025 for the 2026 fiscal year.

Please do not return the Notice of Internet Availability. The Notice of Internet Availability is not a valid proxy.

#### How do I vote if I hold my shares in street name?
If you hold your shares in street name, you will receive instructions from your broker, bank or other nominee describing how to vote your shares. In addition, you may be eligible to vote by internet or telephone if your broker, bank or other nominee participates in the proxy voting program provided by Broadridge. If your bank, brokerage firm or other nominee is participating in Broadridge's program, your voting form will provide instructions. Beneficial owners voting by telephone or internet are subject to the same deadlines as described above for holders of record.

#### What can I do if I change my mind after I submit my proxy?
Your proxy is revocable. If you are a stockholder of record, you can revoke your proxy prior to the completion of voting at the Annual Meeting by:

• delivering an executed, later-dated proxy that is received by the Secretary of the Company before the voting polls close at the Annual Meeting;

• resubmitting your proxy by internet or telephone at any time prior to 10:59 p.m., Central Daylight Time, on May 12, 2026;

• delivering a written notice of revocation of the proxy that is received by the Secretary of the Company before the voting polls close at the Annual Meeting; or

• voting electronically at the virtual Annual Meeting by following the instructions to vote at *www.virtualshareholdermeeting.com/DINO2026*.

If you are a beneficial owner of shares, you may submit new voting instructions by contacting your broker, bank or other nominee or by voting online during the Annual Meeting.

Voting online during the Annual Meeting will replace any previous votes.

#### What happens if I do not give specific voting instructions?
All properly executed proxies, unless revoked as described above, will be voted at the Annual Meeting in accordance with your instructions on your proxy. If a properly executed proxy gives no specific instructions, your shares will be voted in the manner recommended by the Board on all matters presented in this proxy statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting.

If you are a beneficial owner of shares and do not provide your broker, bank or other nominee with specific voting instructions, the rules of the NYSE require that these institutions only vote on matters for which they have discretionary power to vote. If your broker, bank or other nominee does not receive instructions from you on how to vote your shares and they do not have discretion to vote on the matter, then the broker, bank or other nominee will inform the inspector of election that it does not have the authority to vote on the matter with respect to your shares, resulting in a "broker non-vote."

Your broker, bank or other nominee is not permitted to vote on your behalf in the election of directors (Proposal 1) or the advisory vote on the compensation of the Company's named executive officers (Proposal 2), unless you provide specific instructions to them. Accordingly, if you do not provide timely voting instructions to your broker, bank or other nominee that holds your shares, that institution will be prohibited from voting on all of the proposals in its discretion, except the ratification of the appointment of the independent public accounting firm (Proposal 3).

#### How many votes must be present to hold the meeting?
A quorum is necessary for conducting a valid meeting. Holders of a majority of the outstanding shares of our common stock as of the Record Date who are entitled to vote must be present, virtually or by proxy, to constitute a quorum at the Annual Meeting. Abstentions (shares of the Company's common stock for which proxies have been received but for which the holders have abstained from voting) will be counted as present and entitled to vote for purposes of determining a quorum.

#### How are proxies being solicited and who pays the solicitation expenses?
Proxies are being solicited by the Board on behalf of the Company. All expenses of the solicitation, including the cost of preparing and mailing this proxy statement, will be borne by the Company. The Company has retained MacKenzie Partners, Inc. to assist in the solicitation of proxies for the Annual Meeting. For these services, the Company will pay MacKenzie Partners, Inc. $17,500 and will reimburse MacKenzie Partners, Inc. for reasonable out-of-pocket expenses. Additionally, proxies may be solicited by our officers, directors and employees personally or by telephone, e-mail or other forms of communication. The Company may also request banks, brokerage firms, custodians, nominees and fiduciaries to forward proxy materials to beneficial owners of the Company's common stock. The costs of the solicitation, including reimbursements of any forwarding expenses, will be paid by the Company.

## Additional Information
To permit the Company and its stockholders to address stockholder proposals and stockholder director nominations in an informed and orderly manner, SEC rules and the By-Laws establish advance notice procedures with regard to:

• stockholder proposals to be included in the Company's proxy statements;

• stockholder nominations of directors and other proposals to be presented at an annual meeting of stockholders but not included in the Company's proxy statements;

• stockholder nominations of directors to be included in the Company's proxy statements (also known as proxy access); and

• stockholder proxy solicitations for stockholder director nominees (also known as universal proxy).

For a stockholder proposal to be included in the Company's proxy materials for the 2027 annual meeting of stockholders, the proposal must be delivered to, or mailed and received in writing by the Secretary of the Company, at the Company's principal executive offices by December 1, 2026, and otherwise comply with all requirements of the SEC for stockholder proposals and the By-Laws.

Notice of stockholder proposals and stockholder director nominations to be considered at next year's meeting, but not included in the proxy statement, must be in compliance with the notice procedures and informational requirements set forth in Article II, Section 2 and Article III, Section 12, respectively, of the By-Laws. These notices must be delivered to, or mailed and received at the Company's principal executive offices by the Secretary of the Company. To be timely, notice of such proposals and nominations must be submitted not less than 90 calendar days (February 12, 2027) nor more than 120 calendar days (January 13, 2027) prior to the anniversary date of the prior year's annual meeting of stockholders. A copy of the By-Laws may be obtained from the Secretary of the Company at 2323 Victory Avenue, Suite 1400, Dallas, Texas 75219.

The By-Laws provide for proxy access whereby a stockholder (or a group of up to 20 stockholders) who has held at least 3% of our stock for three years or more may nominate up to the greater of two individuals or 20% of the Board and have the nominee(s) included in our proxy statement, provided that the stockholder and nominee(s) satisfy the requirements set forth in the By-Laws. Any stockholder who intends to use these procedures to nominate a candidate for election to the Board for inclusion in our 2026 proxy statement must satisfy the requirements set forth in the By-Laws and must provide notice to the Secretary of the Company, which notice must be delivered, or mailed and received not less than 120 calendar days in advance of the first anniversary of the date the Company's proxy statement was released to stockholders for the preceding year's annual meeting, and in the case of the 2027 proxy statement, no later than December 1, 2026. The notice of proxy access must include information specified in Article II, Section 2(d) and Article III, Section 12 of the By-Laws, including information concerning the nominee and information about the stockholder's ownership of and agreements related to our stock.

Any stockholder who intends to solicit proxies in support of any director nominees must comply with the content requirements of SEC Rule 14a-19 (the SEC's universal proxy rule) at the time it complies with the earlier deadlines in the Company's advance notice provisions of its By-Laws. Thus, if a stockholder intends to solicit proxies in support of any director nominees submitted under the advance notice provisions of the By-Laws for the Company's 2027 annual meeting of stockholders, then such stockholder must also provide proper written notice that sets forth all the information required by SEC Rule 14a-19 to the Secretary of the Company at the principal office of the Company not less than 90 calendar days (February 12, 2027) nor more than 120 calendar days (January 13, 2027) prior to the anniversary date of the prior year's annual meeting of stockholders.

#### ADDITIONAL INFORMATION

#### Stockholders with the Same Address
Each registered stockholder received one copy of the Notice of Internet Availability per account even if at the same address, unless the Company has received contrary instructions from one or more of such stockholders. This procedure called "householding" reduces our printing and distribution costs. Upon written or oral request by writing to Vice President, Investor Relations, HF Sinclair Corporation, 2323 Victory Avenue, Suite 1400, Dallas, Texas 75219, or by telephoning 214-954-6510, the Company will promptly deliver a separate copy of these documents to a stockholder at a shared address to which a single copy has been delivered. A stockholder can notify the Company at the address and phone number listed above if the stockholder wishes to receive separate copies in the future. In addition, stockholders sharing an address who are currently receiving multiple copies may also notify the Company at such address or phone number if they wish to receive only a single copy.

#### Other Matters
The Board does not know of any other matters to be acted upon at the Annual Meeting. However, if any other matter properly comes before the Annual Meeting, the persons voting the proxies will vote them in accordance with their best judgment.

## Appendix A
 **Reconciliations to Amounts Reported under Generally Accepted Accounting Principles** 

***Reconciliations of earnings before interest, taxes, depreciation and amortization ("EBITDA") and EBITDA used in the calculation of our annual incentive awards excluding special items ("AICP Adjusted EBITDA") to amounts reported under generally accepted accounting principles ("GAAP") in financial statements.***

Earnings before interest, taxes, depreciation and amortization, referred to as EBITDA, is calculated as net income (loss) attributable to HF Sinclair stockholders plus or minus, as applicable: (i) income tax expense (benefit), (ii) interest expense, net of interest income and (iii) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA plus or minus (i) lower of cost or market inventory valuation adjustments, (ii) asset impairments, (iii) loss on sale of equity method investment, (iv) loss on early extinguishment of debt, (v) acquisition integration costs, (vi) reclamation costs, (vii) regulatory charges, (viii) severance costs, (ix) pre-close acquisition integration costs, (x) Cheyenne refinery LIFO inventory liquidation costs, (xi) decommissioning costs, (xii) HEP's share of Osage environmental remediation costs, (xiii) gain on sale of real property and (xiv) gain on tariff settlement. AICP Adjusted EBITDA is calculated as Adjusted EBITDA plus or minus (i) non-controlling interest adjustments, (ii) gain on tariff settlement, (iii) FIFO adjustments, (iv) acquisition and integration costs not included in target EBITDA, (v) restructuring costs not included in target, and (vi) other immaterial adjustments.

EBITDA, Adjusted EBITDA and AICP Adjusted EBITDA are not calculations provided for under accounting principles generally accepted in the United States; however, the amounts included in these calculations are derived from amounts included in our consolidated financial statements. EBITDA, Adjusted EBITDA and AICP Adjusted EBITDA should not be considered as alternatives to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA, Adjusted EBITDA and AICP Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. These are presented here because they are widely used financial indicators used by investors, analysts and the Company to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for financial covenants. AICP Adjusted EBITDA is used by management in the calculation of our annual incentive awards.
