Business Definitions 22 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. 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. 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.

Non-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, to their corresponding GAAP measures because certain items that impact these measures are unavailable or cannot be reasonably predicted without unreasonable effort. 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. Adjusted Refinery Gross Margin Per Barrel: Adjusted refinery gross margin is a non-GAAP measure and represents total Refining segment gross margin plus lower of cost or market inventory valuation adjustments, depreciation and amortization and operating expenses, divided by sales volumes of refined products produced at our refineries. Average Per Produced Barrel Sold: Average per produced barrel sold represents the average amount per produced barrel sold, which is a non-GAAP measure. 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. 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 “Reconc iliations 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, 2023. 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. EBITDA Margin: EBITDA margin is calculated as EBITDA divided by sales and other revenues. EBITDA margin is not a calculation based upon GAAP. However, amounts included in EBITDA margin are derived from amounts included in our consolidated financial statements. Enterprise Value: Enterprise value is a measure of a company’s total market capitalization, plus outstanding debt, minus cash and cash equiva lents. Free Cash Flow: Free cash flow is calculated by taking operating cash flow and subtracting capital expenditures. Illustrative Mid-Cycle Refining EBITDA: Illustrative Mid-Cycle Refining EBITDA means, at any time, management’s good faith estimate of the EBITDA of the Refining segment based on an estimate of average historical peak and trough prices through the economic cycle. Operating Expenses Per Barrel: Operating expenses per barrel represents total Refining segment operating expenses, exclusive of depreciation and amortization, divided by sales volumes of refined products produced at our refineries. Payout Ratio: Payout ratio is the sum of dividends and stock buybacks divided by the Adjusted Net Income. 23
