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 HF Sinclair Corporation ("HF Sinclair") and/or 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 using currently available information and expectations as of the date thereof, are not guarantees of future performance and involve certain risks and uncertainties. All statements concerning HF Sinclair's expectations for future results of operations are based on forecasts for our existing operations and do not include the potential impact of any future acquisitions. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that our 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 and HEP to successfully integrate the operations of 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) (such transactions, the "Sinclair Transactions") with their existing operations and fully realize the expected synergies of the Sinclair Transactions or on the expected timeline, the ability of HF Sinclair to successfully integrate the operation of the Puget Sound refinery with its existing operations, the demand for and supply of crude oil and refined products, including uncertainty regarding the effects of the continuing coronavirus ("COVID-19") pandemic on future demand and increasing societal expectations that companies address climate change, risks and uncertainties with respect to the actions of actual or potential competitive suppliers and transporters of refined petroleum products or lubricant and specialty products in HF Sinclair's and HEP's markets, 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 possibility of inefficiencies, curtailments or shutdowns in refinery operations or pipelines, whether due to reductions in demand, accidents, unexpected leaks or spills, unscheduled shutdowns, weather events, infection in the workforce, civil unrest, expropriation of assets, and other economic, diplomatic, legislative, or political events or developments, terrorism, cyberattacks, or other catastrophes or disruptions affecting the operations of HF Sinclair and HEP, production facilities, machinery, pipelines and other logistics assets, equipment, or information systems, or any of the foregoing of our suppliers, customers, or third-party providers, and any potential asset impairments resulting from, or the failure to have adequate insurance coverage for or receive insurance recoveries from, such actions, the effects of current and/or future governmental and environmental regulations and policies, including the effects of current and/or future restrictions on various commercial and economic activities in response to the COVID-19 pandemic and increases in interest rates, the availability and cost of financing to HF Sinclair and HEP, the effectiveness of HF Sinclair's and HEP's capital investments and marketing strategies, HF Sinclair's and HEP's efficiency in carrying out and consummating construction projects, including HF Sinclair's and HEP'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 ability of HF Sinclair to acquire refined or lubricant product operations or pipeline and terminal operations on acceptable terms and to integrate any existing or future acquired operations, the possibility of terrorist or cyberattacks and the consequences of any such attacks, 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 our refined products and create instability in the financial markets that could restrict our ability to raise capital, general economic conditions, including uncertainty regarding the timing, pace and extent of an economic recovery in the United States, a prolonged economic slowdown due to the COVID-19 pandemic, inflation and labor costs, which could result in an impairment of goodwill and/or long-lived asset impairments, and other financial, operational and legal risks. Additional information on risks and uncertainties that could affect the business prospects and performance of HF Sinclair and HEP is provided in the reports filed by HF Sinclair and HEP with the Securities and Exchange Commission.

HF Sinclair#30Business Definitions BPD: the number of barrels per calendar day of crude oil or petroleum products. Blenders Tax Credit (BTC): Federal tax credit where qualified biodiesel blenders are eligible for an income tax credit of $1.00 per gallon of biodiesel or renewable diesel that is blended with petroleum diesel. Biodiesel (FAME): a fuel derived from vegetable oils or animal fats that meet the requirements of ASTM D 6751. Biodiesel is made through a chemical process called transesterification where glycerin is separated from the fat or vegetable oil leaving behind methyl esters (biodiesel) and byproduct glycerin. In the presentation we also refer to this as traditional biodiesel. California's Low Carbon Fuel Standard (LCFS): California program that mandates the reduction in the carbon intensity of transportation fuels by 20% by 2030 Carbon Intensity (CI): the amount of carbon emitted per unit of energy consumed, under LCFS it is a "well-to-wheels" analysis of greenhouse gas emissions in transportation fuel, meaning emissions are quantified from feedstock cultivation through combustion. California Air Resources Board (CARB): California's clean air agency that administers the LCFS program. California Reformulated Gasoline Blend stock for Oxygenate Blending (CARBOB): a petroleum-derived liquid which is intended to be, or is represented as, a product that will constitute California gasoline upon the addition of a specified type and percentage (or range of percentages) of oxygenate to the product after the product has been supplied from the production or import facility at which it was produced or imported. IDR: Incentive Distribution Rights Lubricant: a solvent neutral paraffinic product used in commercial heavy duty engine oils, passenger car oils and specialty products for industrial applications such as heat transfer, metalworking, rubber and other general process oil. Rack Backward: business segment of HF LSP that captures the value between feedstock cost and base oil market prices (transfer prices to rack forward). Rack Forward: business segment of HF LSP that captures the value between bas oil market prices and product sales revenue from customers. RBOB: Reformulated Gasoline Blendstock for Oxygen Blending Refined Bleached Deodorized Soybean Oil (RBD SBO): primary feedstock for FAME Biodiesel currently in the U.S. accounting for 50% of biodiesel production. Soybean Oil is produced by crushing Soybeans which yield 20% Oil and 80% meal. Crude Soybean Oil is then processed (refined) removing impurities, color and odor. Renewable Diesel (RD): a fuel derived from vegetable oils or animal fats that meets the requirements of ASTM 975. Renewable diesel is distinct from biodiesel. It is produced through various processes, most commonly through hydrotreating, reacting the feedstock with hydrogen under temperatures and pressure in the presence of a catalyst. Renewable Diesel is chemically identical to petroleum based diesel and therefore has no blend limit. Renewable Fuel Standard (RFS): national policy administered by EPA requiring a specified volumes of different renewable fuels (primary categories are ethanol and biodiesel) that must replace petroleum-based transportation fuel. " Renewable Identification Number (RIN): a serial number assigned to each batch of biofuel produced until that gallon is blended with gasoline or diesel resulting in the separation of the RIN to be used for compliance. RIN category (D-code) is assigned for each renewable fuel pathway determined by feedstock, production process and fuel type. " D6 RIN (Renewable Fuel) - corn based ethanol, must reduce lifecycle greenhouse gas emissions by at least 20% ■ D5 RIN (Advanced Biofuel) - any renewable biomass except corn ethanol that reduces lifecycle greenhouse gas emissions by at least 50% D4 RIN (Biomass-based Diesel) - biodiesel and renewable diesel, must reduce lifecycle greenhouse gas emissions by at least 50% Renewable Volume Obligation (RVO): the required volume in gallons of biofuel refiners are obligated to blend into the gasoline and diesel pool. EPA sets volumetric standard which are then converted to percent standards based on EIA's projected gasoline and diesel consumption. Equivalence Value (EV): a number used to determine how many RINS can be generated from one gallon of renewable fuel based on the energy content (Btu/gallon) and renewable content of a fuel compared to Ethanol. Ethanol EV is 1.0 RIN per gallon. Biodiesel is 1.5 RINs per gallon and Renewable Diesel is 1.7 RINs per gallon. Sour Crude: crude oil containing quantities of sulfur greater than 0.4 percent by weight, while "sweet crude oil" means crude oil containing quantities of sulfur equal to or less than 0.4 percent by weight. WCS: Western Canada Select crude oil, made up of Canadian heavy conventional and bitumen crude oils blended with sweet synthetic and condensate diluents. WTI: West Texas Intermediate, a grade of crude oil used as a common benchmark in oil pricing. WTI is a sweet crude oil and has a relatively low density. WTS: West Texas Sour, a medium sour crude oil. 30 HF Sinclair#31Non-GAAP 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 to non-GAAP forward-looking measures, estimations or guidance, including Illustrative Mid-Cycle Refining EBITDA, Illustrative Mid-Cycle Adjusted EBITDA and Illustrative Free Cash Flow, to their corresponding GAAP measures because certain items that impact these measures are unavailable or cannot be reasonably predicted without unreasonable effort. Adjusted EBITDA: HF Sinclair 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 lower of cost or market inventory valuation adjustments, gain on sale of real property, severance costs, restructuring charges, Cheyenne refinery LIFO inventory liquidation costs, decommissioning costs, HF Sinclair's pro-rata share of HEP's Osage environmental remediation costs, net of insurance recoveries, acquisition integration and regulatory costs and gain on tariff settlement. HEP 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. 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. HF Sinclair Adjusted EBITDA is reconciled to net income under the section entitled "Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles" in HollyFrontier Corporation'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 our website, www.hfsinclair.com. HEP 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. Adjusted Net Income: Adjusted Net Income (also referred to as Adjusted Net Income attributable to HF Sinclair stockholders) is net income (loss) attributable to HF Sinclair stockholders adjusted to reflect the after-tax effect of special items that HF Sinclair believes are not indicative of its core operating performance that may obscure HF Sinclair's underlying business results and trends. Adjusted Net Income attributable to HF Sinclair stockholders is reconciled to net income under the section entitled "Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles" in 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 our website, www.hfsinclair.com. Capitalization: Capitalization is calculated as Stockholder's Equity, inclusive of non-controlling interest, plus consolidated total debt. Consolidated Net Debt: Consolidated net debt is calculated as total debt, excluding unamortized discount and debt issuance costs, less cash and cash equivalents. Consolidated Net Debt is not a calculation based upon GAAP. However, the amounts included in the Consolidated Net Debt calculation are derived from amounts included in our consolidated financial statements. Debt-To-Capital: Debt-to-Capital is a measurement of financial leverage, calculated as long-term debt divided by total capital. Debt includes all long-term obligations. Total capital includes the debt and shareholders' equity. Distributable Cash Flow: Distributable cash flow (DCF) is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts separately presented in HEP's 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 HEP's 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 HEP management for internal analysis and HEP's performance units. We believe that this measure provides investors with an enhanced perspective of the operating performance of HEP's assets and the cash HEP is generating. HEP's 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 and in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in HEP's 10-Ks starting with the year ended December 31, 2021, available at www.hollyenergy.com. 31 HF Sinclair#32Non-GAAP Definitions 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. Earnings Per Share (EPS): earnings per share is calculated as net income (loss) attributable to stockholders divided by the average number of shares of common stock outstanding. EBITDA: Earnings before interest, taxes, depreciation and amortization, is calculated as net income attributable to HF Sinclair stockholders plus (i) interest expense net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under 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 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 financial covenants. Our historical EBITDA is reconciled to net income under the section entitled "Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles" in "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in HF Sinclair's Form 10-K for the year ended December 31, 2022. Our historical EBITDA for the prior fiscal quarters is reconciled to net income under the section entitled "Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles" in "Item 3. Quantitative and Qualitative Disclosures About Market Risk" in HF Sinclair's Form 10-Qs, all of which are or will be available on our website, www.hfsinclair.com. Enterprise Value: Enterprise value is a measure of a company's total market capitalization, plus outstanding debt, minus cash and cash equivalents. Free Cash Flow: Free cash flow is calculated by taking operating cash flow and subtracting capital expenditures. Illustrative Mid-Cycle EBITDA: Illustrative Mid-Cycle EBITDA means, at any time, management's good faith estimate of the consolidated EBITDA of the company based on an estimate of average historical peak and trough prices through the economic cycle. Leverage Ratio: Leverage ratio is the ratio of consolidated debt to last twelve months Adjusted EBITDA. Payout Ratio: Payout ratio is the sum of dividends and stock buybacks divided by the Adjusted Net Income. 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.
