Safe Harbor Disclosure Statement Statements made during the course of this presentation that are not historical facts are "forward-looking statements" within the meaning of United States federal securities laws. Forward-looking statements are statements that are not historical in nature and may include statements relating to our goals, plans and projections regarding industry and general economic trends, our expected financial position, the anticipated cost savings, revenue enhancement strategies, operational improvements and other benefits from the acquisition of Sinclair Oil Corporation and Sinclair Transportation Company (such transactions, the "Sinclair Transactions"), results of operations or market position and our business strategy. Words such as "anticipate," "project," "will," "expect," "plan," "goal," "forecast," "strategy," "intend," "should," "would," "could," "believe," "may," and similar expressions and statements regarding our plans and objectives for future operations are intended to identify forward-looking statements. Forward-looking statements are inherently uncertain and necessarily involve risks that may affect the business prospects and performance of Holly Energy Partners, L.P. ("HEP"), and actual results may differ materially from those discussed during the presentation. These statements are based on management's beliefs and assumptions and those of HEP's general partner using currently available information and expectations as of the date hereof, are not guarantees of future performance and involve certain risks and uncertainties. Although we and HEP's general partner believe that such expectations reflected in such forward-looking statements are reasonable, neither we nor HEP's general partner can give assurance that such 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: (i) the demand for and supply of crude oil and refined products, including uncertainty regarding the effects of the continuing COVID-19 pandemic on future demand and increasing societal expectations that companies address climate change; (ii) risks and uncertainties with respect to the actual quantities of petroleum products and crude oil shipped on our pipelines and/or terminalled, stored or throughput in our terminals and refinery processing units; (iii) the economic viability of HF Sinclair Corporation, our other customers and our joint ventures' other customers, including any refusal or inability of our or our joint ventures' customers or counterparties to perform their obligations under their contracts; (iv) the demand for refined petroleum products in the markets we serve; (v) our ability to purchase operations and integrate the operations we have acquired or may acquire, including the recently acquired Sinclair Transportation Company LLC business; (vi) our ability to complete previously announced or contemplated acquisitions; (vii) the availability and cost of additional debt and equity financing; (viii) the possibility of temporary or permanent reductions in production or shutdowns at refineries utilizing our 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, civil unrest, expropriation of assets, and other economic, diplomatic, legislative, or political events or developments, terrorism, cyberattacks, or other catastrophes or disruptions affecting our operations, terminal facilities, machinery, pipelines and other logistics assets, equipment, or information systems, or any of the foregoing of our suppliers, customers, or third-party providers or lower gross margins due to the economic impact of the COVID-19 pandemic, 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; (ix) the effects of current and future government regulations and policies, including the effects of current and future restrictions on various commercial and economic activities in response to the COVID-19 pandemic and increases in interest rates; (x) delay by government authorities in issuing permits necessary for our business or our capital projects; (xi) our and our joint venture partners' ability to complete and maintain operational efficiency in carrying out routine operations and capital construction projects; (xii) the possibility of terrorist or cyberattacks and the consequences of any such attacks; (xiii) uncertainty regarding the effects and duration of global hostilities, including the Russia-Ukraine war, and any associated military campaigns which may disrupt crude oil supplies and markets for refined products and create instability in the financial markets that could restrict our ability to raise capital; (xiv) 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; and (xv) the impact of recent or proposed changes in the tax laws and regulations that affect master limited partnerships. Additional information on risks and uncertainties that could affect the business prospects or performance of HEP and HF Sinclair is provided in the reports filed by HEP and HF Sinclair with the Securities and Exchange Commission. All forward-looking statements included in this presentation are expressly qualified in their entirety by the foregoing cautionary statements. The forward-looking statements speak only as of the date made and, other than as required by law, HEP and HF Sinclair undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Definitions NON GAAP MEASUREMENTS: We report certain financial measures that are not prescribed or authorized by U.S. Generally Accepted Accounting Principles ("GAAP"). We discuss management's reasons for reporting these non-GAAP measures below. Although management evaluates and presents these non-GAAP measures for the reasons described below, please be aware that these non-GAAP measures are not alternatives to revenue, operating income, income from continuing operations, net income, or any other comparable operating measure prescribed by GAAP. In addition, these non-GAAP financial measures may be calculated and/or presented differently than measures with the same or similar names that are reported by other companies, and as a result, the non-GAAP measures we report may not be comparable to those reported by others. Also, we have not reconciled non-GAAP forward-looking measures, estimates or guidance, including target leverage or distribution coverage ratios, to their corresponding GAAP measures because certain items that impact these measures are unavailable or cannot be reasonably predicted without unreasonable effort. DISTRIBUTABLE CASH FLOW: Distributable cash flow is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts presented in our consolidated financial statements, with the general exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or as an alternative 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. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. It is also used by management for internal analysis and for our performance units. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating. Historical distributable cash flow for prior years and fiscal quarters is reconciled to net income in a footnote to the table in "Item 6. Selected Financial Data" in HEP's 10-Ks prior to the 10-K for the year ended December 31, 2021 and in a footnote to the "Income, Distributable Cash Flow, Volumes and Balance Sheet Data" table in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" in HEP's 10-Qs, available on our website, www.hollyenergy.com. DISTRIBUTION COVERAGE RATIO: Distribution coverage ratio is the ratio of distributable cash flow attributable to GP and LP unitholders to total GP and LP distributions declared. See page 19 for reconciliation. EBITDA: Earnings before interest, taxes, depreciation and amortization which is calculated as net income attributable to the partners plus or minus (i) interest expense, (ii) interest income, (iii) state income tax (benefit) expense and (iv) depreciation and amortization. EBITDA is not a calculation based upon GAAP. However, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income attributable to the partners or operating income, as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for compliance with financial covenants. Our historical EBITDA for the past is reconciled to net income attributable to the partners in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of HEP's Form 10-K starting with the year ended December 31, 2021. Historical EBITDA for prior years and fiscal quarters is reconciled to net income in a footnote to the table in "Item 6. Selected Financial Data" in HEP's 10-Ks prior to the 10-K for the year ended December 31, 2021 and in a footnote to the "Income, Distributable Cash Flow, Volumes and Balance Sheet Data" table in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" in HEP's 10-Qs, available on our website, www.hollyenergy.com. ADJUSTED EBITDA: Adjusted EBITDA is calculated as EBITDA plus adjustments for extraordinary items, other unusual or non-recurring items, each as determined in accordance with GAAP and identified in the financial statements, such as gain on sales-type leases, gain on significant asset sales, goodwill impairment, share of Osage environmental remediation costs, net of insurance recoveries, acquisition integration and regulatory costs, tariffs and fees not included in revenues due to impacts from lease accounting for certain tariffs and fees, lease payments not included in operating costs and expenses. Portions of our minimum guaranteed pipeline and terminal tariffs and fees for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. These tariffs and fees were previously recorded as revenues prior to the renewal of the throughput agreement, which triggered sales-type lease accounting. Similarly, certain pipeline lease payments were previously recorded as operating costs and expenses, but the underlying lease was reclassified from an operating lease to a financing lease, and these payments are now recorded as interest expense and reductions in the lease liability. Adjusted EBITDA is not a calculation based upon GAAP. However, the amounts included in the Adjusted EBITDA calculation are derived from amounts included in our consolidated financial statements. Adjusted EBITDA should not be considered as an alternative 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. Adjusted EBITDA is not necessarily comparable to similarly titled measures of other companies. Adjusted EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. Adjusted EBITDA is reconciled to net income attributable to the partners in a footnote to the "Income, Distributable Cash Flow and Volumes" table in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in HEP's Form 10-K for the year ended December 31, 2022 or in a footnote to the "Income, Distributable Cash Flow and Volumes" table in HEP's quarterly earnings releases, available on our website, www.hollyenergy.com. For definitions and reconciliations of HF Sinclair Adjusted EBITDA, please refer to HollyFrontier's quarterly earnings releases furnished on Form 8-K for all periods prior to the first quarter of 2022 and in HF Sinclair's quarterly earnings releases furnished on Form 8-K for all periods starting with and occurring after the first quarter of 2022, each of which are or will be available on HF Sinclair's website, www.hfsincalir.com. FREE CASH FLOW: Free cash flow is calculated by taking operating cash flow and subtracting capital expenditures. FREE CASH FLOW AFTER DISTRIBUTIONS: Free cash flow after distributions is calculated by taking operating cash flow and subtracting capital expenditures and distributions to HEP unitholders. Free cash flow after distributions is not based upon GAAP. Free cash flow after distributions should not be considered in isolation or as an alternative 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. Free cash flow after distributions is not necessarily comparable to similarly titled measures of other companies. Free cash flow after distributions is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating. KBPD: Thousand barrels per day. LEVERAGE RATIO: Leverage ratio is the ratio of consolidated debt to last twelve months Adjusted EBITDA. See page 19 for reconciliation. TOTAL TARIFFS AND FEES: Total Tariffs and Fees are calculated as revenues plus tariffs and fees not included in revenues due to impacts from lease accounting for certain tariffs and fees. Portions of our minimum guaranteed pipeline and terminal tariffs and fees for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. These tariffs and fees were previously recorded as revenues prior to the renewal of the throughput agreement, which triggered sales-type lease accounting. See page 18 for reconciliation.
