Item 78.01. ~~Regulation~~Other ~~FD Disclosure.~~Events

OnExchange ~~October 19,~~Offers 2023, Holly Energy Partners, L.P. (the “Partnership”) issued a press release announcing the declaration of its quarterly distribution of $0.35 per common unit for the third quarter of 2023. A copy of the Partnership’s press release is attached hereto as Exhibit 99.1 and ~~incorporated~~Consent ~~herein~~Solicitations ~~in its entirety.~~

Concurrently with the Exchange Offers, HF Sinclair is soliciting the consents (collectively, the “Consent Solicitations”) from the Eligible Holders to adopt certain proposed amendments to the indentures governing the HEP Notes (the “HEP Indentures” and each, an “HEP Indenture”) to, among other things, eliminate from each HEP Indenture, as it relates to each series of HEP Notes (i) substantially all of the restrictive covenants, (ii) certain of the events which may lead to an “Event of Default”, (iii) the U.S. Securities and Exchange Commission (“SEC”) reporting covenant and (iv) the requirement of HEP to offer to purchase the HEP Notes upon a change of control (collectively, the “Proposed Amendments”). The Proposed Amendments will become effective with respect to a particular series of HEP Notes to the extent (i) participation in the Exchange Offer by the relevant series of HEP Notes exceeds 50% of the outstanding principal amount of such series and (ii) all tendered HEP Notes of such series are accepted for exchange in the related Exchange Offer. Eligible Holders of HEP Notes that tender such HEP Notes will be deemed to have given consent to the Proposed Amendments (in respect of the applicable series of HEP Notes tendered).

Eligible Holders will not be permitted to tender their HEP Notes without delivering consents or to deliver consents without tendering their HEP Notes. Tenders of HEP Notes may not be withdrawn after the earlier of (i) the Early Participation Date (as defined below), and (ii) the date on which the applicable supplemental indenture to the corresponding HEP Indenture implementing the applicable Proposed Amendments is executed, unless extended (such date and time, as the same may be extended, the “Withdrawal Deadline”), except in the limited circumstances where additional withdrawal rights are required by law. A valid withdrawal of tendered HEP Notes will also constitute the revocation of the related consent with respect to the applicable HEP Indenture. As used herein, a “valid withdrawal” means valid withdrawal prior to the Withdrawal Deadline.

The Exchange Offers and the Consent Solicitations will expire at 5:00 p.m., New York City time, on November 29, 2023, unless extended or terminated (such time and date, as the same may be extended, the “Expiration Date”). However, Eligible Holders who validly tender and do not validly withdraw their HEP Notes at or prior to 5:00 p.m., New York City time, on November 13, 2023, unless extended or terminated (as the same may be extended, the “Early Participation Date”), will be eligible to receive greater consideration for their HEP Notes than will be available for tenders made after the Early Participation Date but at or prior to the Expiration Date, all as more fully described in the attached press release and in the Exchange Offer Memorandum.

HF Sinclair will return to the HEP Issuers all HEP Notes which are validly tendered and accepted pursuant to the Exchange Offers (the “Returned Notes”), and such Returned Notes will be cancelled.

The Exchange Offers and Consent Solicitations are being made solely pursuant to the conditions set forth in the Exchange Offer Memorandum in a private offering exempt from, or not subject to, registration under the Securities Act of 1933, as amended, and are subject to certain conditions set forth in the Exchange Offer Memorandum, although HF Sinclair may generally waive any such conditions at any time. Notwithstanding the foregoing, HF Sinclair may not waive or modify the condition that the merger of a wholly-owned subsidiary of HF Sinclair with and into HEP, with HEP surviving as an indirect, wholly-owned subsidiary of HF Sinclair (the “Proposed Merger”) shall have been consummated.

HF Sinclair and HEP are in discussions with the current lending group under HEP’s Third Amended and Restated Credit Agreement, dated July 27, 2017, by and among HEP, as borrower, and Wells Fargo Bank, National Association, in its capacity as administrative agent, and the lenders party thereto (as amended, restated,

supplemented or otherwise modified from time to time, the “HEP Credit Agreement”), to obtain an amendment to the HEP Credit Agreement to, among other things, (a) provide a guaranty from HF Sinclair and terminate all guaranties of subsidiaries of HEP, (b) amend the definition of “Investment Grade Rating” in the HEP Credit Agreement to reference the credit rating of HF Sinclair’s senior unsecured indebtedness, (c) eliminate the requirement to deliver separate audited and unaudited financial statements for HEP and its subsidiaries and only provide certain segment-level reporting for HEP with any compliance certificate delivered in accordance with the HEP Credit Agreement and (d) amend certain covenants to eliminate certain restrictions on (i) amendments to intercompany contracts, (ii) transactions with HF Sinclair and its subsidiaries and (iii) investments in and contributions, dividends, transfers and distributions to HF Sinclair and its subsidiaries. There can be no assurance that the administrative agents and lenders party thereto will agree to amend the HEP Credit Agreement in a timely manner, or on acceptable terms, if at all.

Please carefully review the attached press release for further details regarding the Exchange Offers and Consent Solicitations. A copy of HEP’s and HF Sinclair’s joint press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

This announcement does not constitute an offer to sell or purchase, or a solicitation of an offer to sell or purchase, or the solicitation of tenders or consents with respect to, any security. No offer, solicitation, purchase or sale will be made in any jurisdiction in which such an offer, solicitation, or sale would be unlawful. The Exchange Offers and Consent Solicitations are being made solely pursuant to the Exchange Offer Memorandum and only to such persons and in such jurisdictions as is permitted under applicable law.

Cautionary Statement Regarding Forward-Looking Statements

The statements in this Current Report on Form 8-K relating to matters that are not historical facts are “forward-looking statements” based on management’s beliefs and assumptions using currently available information and expectations as of the date hereof, are not guarantees of future performance and involve certain risks and uncertainties, including those contained in HF Sinclair’s and HEP’s filings with the SEC. Forward-looking statements use words such as “anticipate,” “project,” “will,” “expect,” “plan,” “goal,” “forecast,” “strategy,” “intend,” “should,” “would,” “could,” “believe,” “may,” and similar expressions and statements regarding HF Sinclair’s and HEP’s plans and objectives for future operations or the Proposed Merger. Although HEP believes that the expectations reflected in these forward-looking statements are reasonable, HEP cannot assure you that HF Sinclair’s and HEP’s expectations will prove to be correct. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in such statements. Any differences could be caused by a number of factors, including, but not limited to, the ability of HF Sinclair or HEP to consummate the Proposed Merger; the risk that the Proposed Merger does not occur; negative effects from the pendency of the Proposed Merger; the time required to consummate the Proposed Merger; the risk that cost savings, tax benefits and any other synergies from the Proposed Merger may not be fully realized or may take longer to realize than expected; disruption from the Proposed Merger may make it more difficult to maintain relationships with customers, employees or suppliers; the possibility that the market price of HF Sinclair’s common stock will fluctuate prior to the completion of the Proposed Merger causing the value of the merger consideration of the Proposed Merger to change; the risk that certain officers and directors of HF Sinclair and HEP have interests in the Proposed Merger that are different from, or in addition, to the interests they may have as a HF Sinclair stockholder or a HEP unitholder, respectively; the possibility that financial projections by HF Sinclair may not prove to be reflective of actual future results; failure to obtain the required approvals for the Proposed Merger; the focus of management time and attention on the Proposed Merger and other disruptions arising from the Proposed Merger; legal proceedings that may be instituted against HF Sinclair or HEP in connection with the Proposed Merger; HF Sinclair’s and HEP’s ability to successfully integrate the Sinclair Oil Corporation (now known as Sinclair Oil LLC) and Sinclair Transportation Company LLC businesses acquired from The Sinclair Companies (now known as REH Company) (collectively, the “Sinclair Transactions”) with their existing operations and fully realize the expected synergies of the Sinclair Transactions or on the expected timeline; the demand for and supply of crude oil and refined products, including uncertainty regarding the increasing societal expectations that companies address climate change; risks and uncertainties with respect to the actual quantities of petroleum products and crude oil shipped on HEP’s pipelines and/or terminalled, stored or throughput in HEP’s terminals and refinery processing units; the economic viability of HF Sinclair, HEP’s other customers and HEP’s joint ventures’ other customers, including any refusal or inability of HEP’s or HEP’s joint ventures’ customers or counterparties to perform their obligations under their contracts; the demand for refined

petroleum products in the markets we serve; HEP’s ability to purchase operations and integrate the operations we have acquired or may acquire, including the acquired Sinclair Transportation Company LLC business; HEP’s ability to complete previously announced or contemplated acquisitions; the availability and cost of additional debt and equity financing; the possibility of temporary or permanent reductions in production or shutdowns at refineries utilizing HEP’s pipelines, terminal facilities and refinery processing units, due to reductions in demand, accidents, unexpected leaks or spills, unscheduled shutdowns, infection in the workforce, weather events, global health events, civil unrest, expropriation of assets, and other economic, diplomatic, legislative, or political events or developments, terrorism, cyberattacks, or other catastrophes or disruptions affecting HEP’s operations, terminal facilities, machinery, pipelines and other logistics assets, equipment, or information systems, or any of the foregoing of HEP’s suppliers, customers, or third-party providers or lower gross margins due to the economic impact of inflation and labor costs, and any potential asset impairments resulting from, or the failure to have adequate insurance coverage for or receive insurance recoveries from, such actions; the spread between market prices for refined products and market prices for crude oil; the possibility of constraints on the transportation of refined products or lubricant and specialty products; the effects of current and/or future governmental and environmental regulations and policies, including increases in interest rates; delay by government authorities in issuing permits necessary for HEP’s business or HEP’s capital projects; HEP’s and HEP’s joint venture partners’ ability to complete and maintain operational; HF Sinclair’s and HEP’s efficiency in carrying out and consummating construction projects, including HF Sinclair’s ability to complete announced capital projects on time and within capital guidance; HF Sinclair’s and HEP’s ability to timely obtain or maintain permits, including those necessary for operations or capital projects; the possibility of terrorist or cyberattacks and the consequences of any such attacks; uncertainty regarding the effects and duration of global hostilities, including the Israel-Gaza conflict, the Russia-Ukraine war, and any associated military campaigns which may disrupt crude oil supplies and markets for HF Sinclair’s refined products and create instability in the financial markets that could restrict HF Sinclair’s ability to raise capital; general economic conditions, including economic slowdowns caused by a local or national recession or other adverse economic condition, such as periods of increased or prolonged inflation; the impact of recent or proposed changes in the tax laws and regulations that affect master limited partnerships; the outcome of the Exchange Offers and Consent Solicitations; and other business, financial, operational and legal risks and uncertainties detailed from time to time in HF Sinclair’s and HEP’s SEC filings, whether or not related to the Exchange Offers and Consent Solicitations.
