Disclaimers

Forward Looking Statements:

Delek US Holdings, Inc. ("Delek US") and Delek Logistics Partners, LP ("Delek Logistics"; and collectively with Delek US, "we" or "our") are traded on the New York Stock Exchange in the United States under the symbols "DK" and "DKL", respectively. These slides and any accompanying oral and written presentations contain forward-looking statements within the meaning of federal securities laws that are based upon current expectations and involve a number of risks and uncertainties. Statements concerning current estimates, expectations and projections about future results, performance, prospects, opportunities, plans, actions and events and other statements, concerns, or matters that are not historical facts are "forward-looking statements," as that term is defined under the federal securities laws. Words such as "may," "will," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," "appears," "projects" and similar expressions, as well as statements in future tense, identify forward-looking statements.

These forward-looking statements include, but are not limited to, the statements regarding the following: financial and operating guidance for future and uncompleted financial periods; financial strength and flexibility; potential for and projections of growth; return of cash to shareholders, stock repurchases and the payment of dividends, including the amount and timing thereof; cost reductions; crude oil throughput; crude oil market trends, including production, quality, pricing, demand, imports, exports and transportation costs; competitive conditions in the markets where our refineries are located; the performance of our joint venture investments, including Red River and Wink to Webster, and the benefits, flexibility, returns and EBITDA therefrom; the potential for, and estimates of cost savings and other benefits from, acquisitions, divestitures, dropdowns and financing activities; the attainment of certain regulatory benefits; long-term value creation from capital allocation; targeted internal rates of return on capital expenditures; execution of strategic initiatives and the benefits therefrom, including cash flow stability from business model transition and approach to renewable diesel; and access to crude oil and the benefits therefrom.

Investors are cautioned that the following important factors, among others, may affect these forward-looking statements: uncertainty related to timing and amount of value returned to shareholders; risks and uncertainties with respect to the quantities and costs of crude oil we are able to obtain and the price of the refined petroleum products we ultimately sell, including uncertainties regarding future decisions by OPEC regarding production and pricing disputes between OPEC members and Russia; uncertainty relating to the impact of the COVID-19 outbreak on the demand for crude oil, refined products and transportation and storage services; Delek US' ability to realize cost reductions; risks related to Delek US' exposure to Permian Basin crude oil, such as supply, pricing, production and transportation capacity; gains and losses from derivative instruments; management's ability to execute its strategy of growth through acquisitions and the transactional risks associated with acquisitions and dispositions; acquired assets may suffer a diminishment in fair value as a result of which we may need to record a write-down or impairment in carrying value of the asset; changes in the scope, costs, and/or timing of capital and maintenance projects; the ability of the Wink to Webster joint venture to construct the long-haul pipeline; the ability of the Red River joint venture to expand the Red River pipeline; the possibility of litigation challenging renewable fuel standard waivers; the ability to grow the Big Spring Gathering System; operating hazards inherent in transporting, storing and processing crude oil and intermediate and finished petroleum products; our competitive position and the effects of competition; the projected growth of the industries in which we operate; general economic and business conditions affecting the geographic areas in which we operate; and other risks contained in Delek US' and Delek Logistics' filings with the United States Securities and Exchange Commission.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not be accurate indications of the times at, or by which such performance or results will be achieved. Forward-looking information is based on information available at the time and/or management's good faith belief with respect to future events, and is subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in the statements. Neither Delek US nor Delek Logistics undertakes any obligation to update or revise any such forward-looking statements.

Non-GAAP Disclosures:

Our management uses certain "non-GAAP" operational measures to evaluate our operating segment performance and non-GAAP financial measures to evaluate past performance and prospects for the future to supplement our GAAP financial information presented in accordance with U.S. GAAP. These financial and operational non-GAAP measures are important factors in assessing our operating results and profitability and include:

• Adjusting items - certain identified infrequently occurring items, non-cash items, and items that are not attributable to or indicative of our on-going operations or that may obscure our underlying results and trends;
• Earnings before interest, taxes, depreciation and amortization ("EBITDA") - calculated as net income attributable to Delek US or Delek Logistics, as applicable, adjusted to add back interest expense, income tax expense, depreciation and amortization;
• Adjusted Segment Earnings - calculated as reported GAAP contribution margin (or revenue less cost of materials and other and operating expenses) less estimated general and administrative expenses specific to the segment (and excluding allocations of corporate general and administrative expenses), adjusted to include gain (loss) from disposal of property and equipment, and adjusted to reflect the relevant Adjusting items (defined above). While this measure does not exactly represent EBITDA, it may be considered a reasonably comparable measure to EBITDA, in that it includes all identified material cash income and expense items, and excludes depreciation, amortization, interest and income taxes. This definition of Adjusted Segment Earnings (or, individually, Adjusted Refining Segment Earnings, Adjusted [Logistics] Midstream Segment Earnings or Adjusted Retail Segment Earnings) is specific to this communication only and the exhibits referenced herein, and may not correlate to the use of the term 'Adjusted Contribution Margin' or 'Adjusted Segment Contribution Margin' as a non-GAAP measure in other of our filings with the SEC. Accordingly, always refer to the respective Non-GAAP Disclosures section, included in each of our filings that contain non-GAAP measures, for more information regarding the use of and definition of non-GAAP measures and terms, as they relate to that specific SEC filing; and
• Net debt- calculated as long-term debt (the most comparable GAAP measure) including both current and non-current portions, less cash and cash equivalents as of a specific balance sheet date. This is an important measure to monitor leverage and evaluate the balance sheet.

We believe these non-GAAP measures are useful to investors, lenders, ratings agencies and analysts to assess our financial results and ongoing performance in certain segments because, when reconciled to their most comparable GAAP financial measure, they provide important information regarding trends that may aid in evaluating our performance as well improved relevant comparability between periods, to peers or to market metrics. Non-GAAP measures have important limitations as analytical tools, because they exclude some, but not all, items that affect contribution margin, operating income (loss), and net income (loss). These measures should not be considered substitutes for their most directly comparable U.S. GAAP financial measures.

Additionally, because the non-GAAP measures referenced above may be defined differently by other companies in its industry, Delek US's definition may not be comparable to similarly titled measures of other companies. See the accompanying tables in the appendix for a reconciliation of these non-GAAP measures to the most directly comparable GAAP measures.

We are unable to provide a reconciliation of forward-looking estimates of EBITDA or other forward-lookingnon-GAAP measures because certain information needed to make a reasonable forward-looking estimate of net income or other forward-looking GAAP measures is difficult to estimate and dependent on future events, which are uncertain or outside of our control. Accordingly, a reconciliation to the most comparable GAAP measure is not available without unreasonable effort. These amounts that would require unreasonable effort to quantify could be significant, such that the amount of the projected GAAP measure could vary substantially from projected non-GAAP measure.
