The Investor Presentation is incorporated into this Item 7.01 by this reference and will also be available on the Company's website at www.delekus.com.

The information in this Item 7.01 is being furnished, not filed, pursuant to Regulation FD. Accordingly, the information in Item 7.01 of this report will not be incorporated by reference into any registration statement filed by the Company under the Securities Act of 1933, as amended, unless specifically identified therein as being incorporated therein by reference. The furnishing of the information in this report is not intended to, and does not, constitute a determination or admission by the Company that the information in this report is material or complete, or that investors should consider this information before making an investment decision with respect to any security of the Company or any of its affiliates.

Forward-Looking Statements

This report contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These forward-looking statements reflect our current estimates, expectations and projections about our future results, performance, prospects and opportunities. Forward-looking statements include, among other things, the information concerning our possible future results of operations, business and growth strategies, financing plans, expectations that regulatory developments or other matters will or will not have a material adverse effect on our business or financial condition, our competitive position and the effects of competition, the projected growth of the industry in which we operate, and the benefits and synergies to be obtained from our completed and any future acquisitions, statements of management’s goals and objectives, and other similar expressions concerning matters that are not historical facts. 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.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily 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. Important factors that, individually or in the aggregate, could cause such differences include, but are not limited to:

• volatility in our refining margins or fuel gross profit as a result of changes in the prices of crude oil, other feedstocks and refined petroleum products;

• risk factors relating to the Delek/Alon Merger, including but not limited to risks surrounding the combining of operations, financial position and cash flows as well as systems, processes and controls going forward, as further discussed in Part I, Item 1A, "Risk Factors";

• our ability to execute our strategy of growth through acquisitions and the transactional risks inherent in such acquisitions;

• acquired assets may suffer a diminishment in fair value, which may require us to record a write-down or impairment;

• liabilities related to, and the effects of, the sale of the Retail Entities (as defined below);

• reliability of our operating assets;

• competition;

• changes in, or the failure to comply with, the extensive government regulations applicable to our industry segments;

• changes in interpretations, assumptions and expectations regarding the Tax Cuts and Jobs Act, including additional guidance that may be issued by federal and state taxing authorities;

• diminution in value of long-lived assets may result in an impairment in the carrying value of the assets on our balance sheet and a resultant loss recognized in the statement of operations;

• general economic and business conditions affecting the southern, southwestern and western United States, particularly levels of spending related to travel and tourism;

• volatility under our derivative instruments;

• deterioration of creditworthiness or overall financial condition of a material counterparty (or counterparties);

• unanticipated increases in cost or scope of, or significant delays in the completion of, our capital improvement and periodic turnaround projects;

• risks and uncertainties with respect to the quantities and costs of refined petroleum products supplied to our pipelines and/or held in our terminals;

• operating hazards, natural disasters, casualty losses and other matters beyond our control;

• increases in our debt levels or costs;

• changes in our ability to continue to access the credit markets;

• compliance, or failure to comply, with restrictive and financial covenants in our various debt agreements;

• the inability of our subsidiaries to freely make dividends, loans or other cash distributions to us;

• seasonality;

• acts of terrorism aimed at either our facilities or other facilities that could impair our ability to produce or transport refined products or receive feedstocks;

• changes in the cost or availability of transportation for feedstocks and refined products; and

• other factors discussed under Item 1A, Risk Factors and Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations and in our other filings with the SEC.

In light of these risks, uncertainties and assumptions, our actual results of operations and execution of our business strategy could differ materially from those expressed in, or implied by, the forward-looking statements, and you should not place undue reliance upon them. In addition, past financial and/or operating performance is not necessarily a reliable indicator of future performance, and you should not use our historical performance to anticipate future results or period trends. We can give no assurances that any of the events anticipated by any forward-looking statements will occur or, if any of them do, what impact they will have on our results of operations and financial condition.

Forward-looking statements speak only as of the date the statements are made. We assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect thereto or with respect to other forward-looking statements.
