INTRODUCTION

This Amendment No. 1 to the Rule 13e-3 Transaction Statement on Schedule 13E-3 (as originally filed on September 22, 2023, and together with the exhibits hereto and thereto, this “Amended Transaction Statement”), is being filed with the U.S. Securities and Exchange Commission (the “SEC”) pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by: (i) Holly Energy Partners, L.P., a Delaware limited partnership (“HEP”) and the issuer of the common units representing limited partner interests in HEP (“HEP Common Units,” and the holders of HEP Common Units, the “HEP Unitholders”) that are subject to the Rule 13e-3 transaction; (ii) HF Sinclair Corporation, a Delaware corporation (“HF Sinclair”); (iii) Navajo Pipeline Co., L.P., a Delaware limited partnership and an indirect wholly owned subsidiary of HF Sinclair (“HoldCo”); (iv) Holly Logistic Services, L.L.C., a Delaware limited liability company, the general partner (the “General Partner”) of HEP Logistics Holdings, L.P. (“HLH”); (v) HLH, a Delaware limited partnership and the general partner of HEP; and (vi) Holly Apple Holdings LLC, a wholly owned subsidiary of HoldCo (“Merger Sub”). Collectively, the persons filing this Amended Transaction Statement are referred to as the “filing persons.”

This Amended Transaction Statement relates to the Agreement and Plan of Merger, dated as of August 15, 2023 (as the same may be amended or supplemented from time to time, the “Merger Agreement”), by and among HF Sinclair, HEP, HoldCo, the General Partner, HLH and Merger Sub, pursuant to which Merger Sub will merge with and into HEP, with HEP surviving as an indirect, wholly owned subsidiary of HF Sinclair (the “Merger”).

Under the terms of the Merger Agreement, at the effective time of the Merger, each outstanding HEP Common Unit other than the HEP Common Units owned by HF Sinclair, HoldCo, HLH, the General Partner and their respective affiliates, will be converted into the right to receive (i) 0.315 (the “Exchange Ratio”) shares of common stock, par value $0.01 per share, of HF Sinclair (the “HF Sinclair Common Stock” and such issuance, the “HF Sinclair Stock Issuance”) and (ii) $4.00 in cash, without interest (the “Cash Consideration” and, together with the shares of HF Sinclair Common Stock to be issued in the Merger, the “Merger Consideration”). The receipt of Merger Consideration in exchange for HEP Common Units held by the HEP Unitholders other than HF Sinclair and its subsidiaries pursuant to the Merger will be a taxable transaction to U.S. Holders. See “United States Federal Income Tax Consequences” in the Joint Proxy Statement/Prospectus (as defined below).

The Merger will become effective upon the filing of a properly executed certificate of merger with the Secretary of State of the State of Delaware or at such later date and time as may be agreed by HF Sinclair and HEP in writing and set forth in the certificate of merger.

HF Sinclair will not issue any fractional shares in the Merger. Instead, each holder of HEP Common Units that are converted pursuant to the Merger Agreement who otherwise would have received a fraction of a share of HF Sinclair Common Stock will be entitled to receive, in lieu thereof, a cash payment (without interest and rounded to the nearest cent) in an amount equal to the product of (i) the aggregated amount of the fractional interest in shares of HF Sinclair Common Stock to which such holder would otherwise be entitled to receive pursuant to the Merger Agreement and (ii) an amount equal to the average of the volume weighted average price per share of HF Sinclair Common Stock on the New York Stock Exchange (the “NYSE”) (as reported by Bloomberg L.P., or, if not reported therein, in another authoritative source mutually selected by HF Sinclair and the General Partner) on each of the ten consecutive trading days ending with the complete trading day immediately prior to the closing date of the Merger.

Holders of shares of HF Sinclair Common Stock prior to the Merger will continue to own their existing shares of HF Sinclair Common Stock. In connection with the Merger, (i) HLH’s non-economic general partner interest in HEP, (ii) HLH’s special general partner interest in HEP (the “Special General Partner Interest”), and (iii) the HEP Common Units owned by HF Sinclair and its subsidiaries, including HoldCo, will not be cancelled, will not be converted into the Merger Consideration and will remain outstanding following the Merger as a non-economic general partner interest in HEP, a Special General Partner Interest in HEP and as HEP Common Units, respectively.

The closing of the Merger will take place on the third business day after the satisfaction or waiver of the conditions set forth in the Merger Agreement (other than conditions that by their nature are to be satisfied at the closing but subject to the satisfaction or waiver of those conditions), or at such other place, date and time as HF Sinclair and HEP may agree.

The conflicts committee (the “HF Sinclair Conflicts Committee”) of the board of directors of HF Sinclair (the “HF Sinclair Board”) has unanimously (i) determined that the Merger Agreement and the various transactions contemplated by the Merger Agreement, including the Merger and the HF Sinclair Stock Issuance (the “Transactions”), are advisable and in the best interests of HF Sinclair and the HF Sinclair Stockholders, (ii) approved the Merger Agreement and the Transactions, including the Merger and the HF Sinclair Stock Issuance, on the terms and subject to the conditions set forth in the Merger Agreement, (iii) recommended that the HF Sinclair Board approve the Merger Agreement and the Transactions, including the Merger and the HF Sinclair Stock Issuance, on the terms and subject to the conditions set forth in the Merger Agreement, and (iv) resolved and recommended that the HF Sinclair Board resolve, to (a) direct that the HF Sinclair Stock Issuance be submitted to a vote of the HF Sinclair Stockholders for approval at the HF Sinclair Special Meeting and (b) recommend approval of the HF Sinclair Stock Issuance by the HF Sinclair Stockholders at the HF Sinclair Special Meeting (as defined below).

The HF Sinclair Board (acting, in part, based upon the recommendation of the HF Sinclair Conflicts Committee) has unanimously (i) determined that the Merger Agreement and the Transactions, including the Merger and the HF Sinclair Stock Issuance, are advisable and in the best interests of HF Sinclair and the HF Sinclair Stockholders, (ii) approved the Merger Agreement and the Transactions, including the Merger and the HF Sinclair Stock Issuance, on the terms and subject to the conditions set forth in the Merger Agreement, (iii) directed that the HF Sinclair Stock Issuance be submitted to a vote of the HF Sinclair Stockholders for approval at the HF Sinclair Special Meeting and (iv) resolved to recommend approval of the HF Sinclair Stock Issuance by the HF Sinclair Stockholders at the HF Sinclair Special Meeting.

The conflicts committee (the “HEP Conflicts Committee”) of the board of directors of the General Partner (the “GP Board”) has unanimously and in good faith (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of HEP, including the HEP Unitholders other than HF Sinclair, HoldCo, HLH, the General Partner and their respective Affiliates, including officers and directors of such entities and their Affiliates (the “HEP Unaffiliated Unitholders”), (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger (the foregoing constituting “Special Approval” for all purposes of the Second Amended and Restated Agreement of Limited Partnership of HEP, dated as of October 31, 2017, as may be further amended, modified or supplemented from time to time, including Section 7.9(a) thereof) on the terms and subject to the conditions set forth in the Merger Agreement, (iii) recommended that the GP Board approve the Merger Agreement and the transactions contemplated thereby, including the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, and (iv) resolved and recommended that the GP Board resolve to (a) direct that the Merger Agreement and the Merger be submitted to a vote of the HEP Unitholders for approval and (b) recommend approval of the Merger Agreement and the Merger by the HEP Unitholders at the HEP Special Meeting (as defined below).

The GP Board (acting, in part, based upon the recommendation of the HEP Conflicts Committee) has unanimously and in good faith (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of HEP, including the HEP Unaffiliated Unitholders, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, (iii) directed that the Merger Agreement and the Merger be submitted to a vote of the HEP Unitholders for approval and (iv) resolved to recommend approval of the Merger Agreement and the Merger by the HEP Unitholders at the HEP Special Meeting.

In connection with the Merger, HF Sinclair will hold a special meeting of its stockholders (as the same may be adjourned or postponed, the “HF Sinclair Special Meeting”), and HEP will hold a special meeting of its unitholders (as the same may be adjourned or postponed, the “HEP Special Meeting”).

At the HF Sinclair Special Meeting, the HF Sinclair Stockholders will be asked to consider and vote on proposals to (i) approve the issuance of shares of HF Sinclair Common Stock to HEP Unitholders pursuant to the Merger Agreement (the “HF Sinclair Stock Issuance Proposal”) and (ii) approve the adjournment of the HF Sinclair Special Meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes at the time of the HF Sinclair Special Meeting to approve the HF Sinclair Stock Issuance Proposal. The approval by the HF Sinclair Stockholders of the HF Sinclair Stock Issuance Proposal is required by the NYSE rules relating to issuances of securities to certain related parties.

At the HEP Special Meeting, the HEP Unitholders will be asked to consider and vote on proposals to (i) approve the Merger Agreement and the transactions contemplated thereby (the “Merger Proposal”) and (ii) approve the adjournment of the HEP Special Meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes at the time of the HEP Special Meeting to approve the Merger Proposal. Pursuant to the Merger Agreement, HF Sinclair has agreed that it will vote, or cause to be voted, all HEP Common Units then owned beneficially or of record by HF Sinclair or any of its subsidiaries in favor of the Merger Proposal. HF Sinclair currently holds approximately 47% of the issued and outstanding HEP Common Units through its subsidiaries, along with the non-economic general partner interest and the Special General Partner Interest.

Exhibit (c)(2)(A) BOARD PRESENTATION May 1, 2023 NYSE: DINO


Important Notice This presentation (this “Presentation”) was prepared by Barclays Capital Inc. (“we” or “Barclays”), at the request of HF Sinclair Corporation (the “Company”) in the context of an evaluation of the potential acquisition by the Company of the equity interests of Holly Energy Partners L.P. (the “Target”) not currently owned by the Company (the “Potential Transaction”). This Presentation is the intellectual property of Barclays and was prepared exclusively by Barclays in order to assist the Company in the context of an evaluation of the Potential Transaction. The effective date of this Presentation is May 1, 2023 and it is valid only for the date specified herein. In connection with the Presentation Barclays has reviewed (a) a comparison of the historical financial results and present financial condition of the Target and the Company with those of other companies that we deemed relevant, (b) a comparison of the financial terms of the proposed transaction with the financial terms of certain other transactions that we deemed relevant, and (c) published estimates of independent research analysts with respect to the future financial performance and price targets of the Company and the Target. Barclays may also have obtained information not made available by the Company, including, among other items, demographic, macroeconomic, regulatory, and market information related to the Target and its business mentioned in this Presentation from acknowledged and reliable public sources or from sources that to Barclays’ best knowledge were considered reliable. Barclays did not conduct any independent verification of any such information or any other information received from the Company or the Target involved in the execution of this Presentation. Barclays does not assume liability or responsibility for the precision, accuracy, or completeness of such information, nor does it express any opinion about the reliability of the information supplied and highlights that any errors or changes in such information could significantly affect Barclays’ analysis. In addition, in preparing this Presentation, we have not conducted a physical inspection of the properties and facilities of the Company or the Target and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company or the Target. Barclays’ work does not intend to be an audit of financial statements or any other information supplied to us by the Company or the Target. Our work took into account the relevance of each item, and therefore assets, rights, and obligations of low relative relevance may not have been the object of detailed analysis. During the preparation of this Presentation, Barclays has adopted as an assumption, with the express consent of the Company, the reliability, accuracy, veracity, completeness, sufficiency, and integrity of all data which was prepared or discussed, and Barclays has not made or obtained any independent evaluation or appraisal of the assets or liabilities of the Company or the Target or their solvency and has further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make any such information inaccurate or misleading. The estimates and forecasts contained in this Presentation are inherently subject to uncertainties and various events or factors that are beyond the control of the Company and the Target, as well as of Barclays, especially those whose occurrence depend on future and uncertain events. There is no guarantee that the estimates and projections used in this Presentation will be effectively achieved. The information herein contained relating to the accounting and financial position of the Company, the Target and their markets, are those available as of May 1, 2023 unless otherwise stated herein. Any changes in those positions can affect the results of this Presentation. Barclays does not assume any obligation of updating, reviewing, reaffirming or amending this Presentation, as a result of disclosure of any subsequent information after the date hereof or as result of any other subsequent event or circumstances that may occur after the date of this Presentation. This Presentation was generated according to the economic and market conditions, among others, existing on the date of its preparation, so the conclusion presented is subject to variations of several factors, over which Barclays does not have any control. There is no guarantee that the assumptions, estimates, forecasts, partial or total results, or conclusions used or presented in this Presentation will be effectively reached or verified, in part or in whole. The future results of the Company and the Target may be different from the results included in the projections, and differences may be significant, as a result of several factors, including, but not limited to, changes in the market conditions. This Presentation was prepared to assist the Company in evaluating the Target, but it does not intend to be the only reference for such evaluation, and is not in any way a guarantee in relation to the past or future performance of the Company or the Target nor a formal appraisal, and therefore, it does not contain all the information necessary for such objective, and consequently does not represent nor constitute a proposal, solicitation, suggestion, advice, recommendation, fairness opinion or solvency opinion by Barclays in connection with the proposed transaction referred to herein or any other transaction related to such transaction, as such decision is the sole responsibility of the Company, and Barclays does not assume any responsibility for such decision. The Company shall make its own analysis in relation to any transaction involving the Target, and shall consult its own accounting, tax, and legal advisors before making its own decision about such transaction. This Presentation is confidential and cannot be circulated, copied, published, reproduced or used in any form, neither can it be archived, included or referenced, in whole or in part, in any document, without the previous written consent of Barclays. Barclays highlights that its services do not include advisory services of any nature, such as legal, tax or accounting. Barclays accepts no liability whatsoever for any losses arising from the use of this Presentation or reliance on information contained herein. This Presentation shall be read and interpreted according to the restrictions and qualifications previously mentioned.
