8 HollyFrontier Renewables Strategic Rationale  Plan to expand the renewables segment to become a meaningful part of HollyFrontier’s cash flow and diversify from traditional petroleum fuels refining  Consumer preference for low carbon fuels continues to grow, driving expansion of government renewable fuel programs, requirements and incentives to more states in the US and across the world  HollyFrontier can leverage utilities and infrastructure at existing refineries for renewables production  Integrated solution to the Renewable Fuels Standard (RFS)  Strengthens ESG profile Renewables Business Profile Expected capacity to produce over 200 million gallons per year of renewable diesel with feedstock flexibility  Artesia Renewable Diesel Unit  ~120 million gallons per year capacity co- located at Artesia refinery  Cheyenne Renewable Diesel Unit  ~90 million gallons per year capacity through conversion of existing refinery  Pre-Treatment Unit (PTU)  Flexibility to process multiple feedstocks for both Artesia and Cheyenne  Expected total capital spend of approximately $650-$750 million  Expected consolidated IRR 20-30%

9 HollyFrontier Renewable Diesel HollyFrontier is expected to produce over 200 million gallons per year of renewable diesel Renewable Diesel Defined  Renewable diesel is a cleaner burning fuel with over 50% lower greenhouse (GHG) emissions than conventional diesel  Renewable diesel is not biodiesel  Same feedstock  Different process  Chemically identical to conventional diesel  No blend limit, existing diesel fleet can run 100% with no risk to engine operation Economics  Increasing renewable diesel demand driven by diesel consumption and low-carbon fuel policy  Renewable diesel margin supported by RIN, Low Carbon Fuel Standard (LCFS) value and Blender’s Tax Credit (BTC) when in effect  Every gallon of renewable diesel generates 1.7 D4 RINs  Renewable diesel production expected to generate >1,000,000 LCFS credits year 1*  Every gallon of renewable diesel earns $1.00 in Blender’s Tax Credit in 2022 *Credit generation declines over time as the Carbon Intensity (CI) standard falls because credit generation is determined by renewable diesel Carbon Intensity value compared to the standard set by the California Air Resources Board

10 Artesia Renewable Diesel Unit 10 Expected capacity to produce ~120 million gallons per year of renewable diesel Project Details  HFC to construct greenfield Renewable Diesel Unit (RDU) co-located at the Navajo refinery  Includes rail infrastructure and storage tanks  Existing hydrogen and utilities provided by the refinery  Estimated in-service date: 1Q 2022 Project Economics  Estimated capital costs of $350 million  Expected IRR of 20-30%  Expected average free cash flow of ~$100mm per year excluding BTC* * Blenders tax credit

11 Cheyenne Renewable Diesel Unit * Blenders tax credit Expected capacity to produce ~90 million gallons per year of renewable diesel Project Details  HFC to convert existing hardware to produce renewable diesel  Ceased crude refining operations in early August 2020  Utilizing existing infrastructure allows for shorter timeline and lower cost than greenfield construction  Estimated in-service date: 1Q 2022 Project Economics  Estimated capital costs of $125 - $175 million  Expected IRR of 20-30%  Expected average free cash flow of ~$40mm per year excluding BTC*

12 Pre-Treatment Unit Feedstock Flexibility Pre-treatment capacity allows our renewable diesel plants to process a variety of feedstock Project Details  HFC to construct pre-treatment unit to provide flexibility and upgrade of feedstock  Designed to treat degummed “unrefined” soybean oil, bleachable fancy tallow and distillers corn oil  Feedstock flexibility mitigates single feedstock risk  Lower carbon intensity feedstock (tallow and distillers corn oil) increases LCFS value  Located in Artesia, NM  Expected to cover ~80% of HollyFrontier’s total feedstock requirements  Estimated in-service date: first half of 2022 Economics  Estimated capital costs of $175-$225 million  Expected IRR 10-15% base case, but designed to protect the returns of our renewables business against potential volatility in the feedstock markets  Expected average free cash flow of ~$25mm per year

13 Operate a system of petroleum product and crude pipelines, storage tanks, distribution terminals and loading rack facilities located near HFC’s refining assets in high growth markets  Revenues are nearly 100% fee-based with de minimis commodity risk  Customer base consisting of refining companies (contracts not with E&Ps)  Minimum Volume Commitments (MVCs) comprise over 75% of total revenue1  Substantially all MVC revenues tied to PPI and/or FERC  IDR simplification transaction completed in 2017 Financial Guidance & Targets:  Expect to maintain annual distribution of $1.40 per LP unit for 2021  Target distribution coverage at or above 1.3x (2x as of YE20)  Target leverage of 3.0-3.5x (4x as of YE20)  Self-funding all planned capital expenditures and distributions Holly Energy Partners Business Profile 1.

Definitions Internal Rate of Return (IRR): a metric used in capital budgeting to estimate the profitability of potential investments. The internal rate of return is a discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero. Includes management’s assumptions on future returns. 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 or guidance to their corresponding GAAP measures because certain items that impact these measures are unavailable or cannot be reasonably predicted without unreasonable effort. 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. 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 I 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 green house 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 Blendstock 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. CAGR: The compound annual growth rate is calculated by dividing the ending value by the beginning value, raise the result to the power of one divided by the period length, and subtract one from the subsequent result. CAGR is the mean annual growth rate of an investment over a specified period of time longer than one year. Debt-To-Capital: A measurement of a company's financial leverage, calculated as the company's long term debt divided by its total capital. Debt includes all long-term obligations. Total capital includes the company's 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 exception of excess cash flows over earnings of SLC Pipeline, maintenance capital expenditures and distributable cash flow from discontinued operations. 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. We believe that this measure provides investors an enhanced perspective of the operating performance of HEP’s assets and the cash HEP is generating. HEP’s historical net income is reconciled to distributable cash flow in "Item 6. Selected Financial Data" of HEP's 2020 10-K filed February 24, 2021, available on our website, www.hollyfrontier.com EBITDA: Earnings before interest, taxes, depreciation and amortization, which we refer to as EBITDA, is calculated as net income plus (i) interest expense net of interest income, (ii) income tax provision, and (iii) depreciation, depletion 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 “Reconciliation to Amounts Reported Under Generally Accepted Accounting Principles” in HollyFrontier Corporation’s 2020 10-K filed February 24, 2021, and the associated earnings releases furnished on Form 8-K, each of which are available on our website, www.hollyfrontier.com Adjusted ABITDA: 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 inventory valuation adjustments, goodwill or long- lived asset impairments, severance costs or acquisition integration and regulatory costs. 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 under the section entitled “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” in HollyFrontier’s earnings releases furnished on Form 8-K, each of which are available on our website, www.hollyfrontier.com. Free Cash Flow: Calculated by taking operating cash flow and subtracting capital expenditures. 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. 33
