Organization and Basis of Presentation	Organization and Basis of Presentation Delek US Holdings, Inc. operates through its consolidated subsidiaries, which include Delek US Energy, Inc. ("Delek Energy") (and its subsidiaries) and Alon USA Energy, Inc. ("Alon") (and its subsidiaries). The terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Delek and its consolidated subsidiaries. Delek's common stock is listed on the New York Stock Exchange ("NYSE") under the symbol "DK." Our condensed consolidated financial statements include the accounts of Delek and its subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited consolidated financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on March 1, 2023 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2022 included in our Annual Report on Form 10-K. Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics", NYSE:DKL), which is a variable interest entity ("VIE"). On June 1, 2022, DKL Delaware Gathering, LLC, a subsidiary of the Delek Logistics, acquired 100% of the limited liability company interests in 3 Bear Delaware Holding – NM, LLC ("3 Bear") from 3 Bear Energy – New Mexico LLC (subsequently renamed to Delek Delaware Gathering ("Delaware Gathering")), related to their crude oil and natural gas gathering, processing and transportation businesses, as well as water disposal and recycling operations, located in the Delaware Basin of New Mexico (the "Delaware Gathering Acquisition"). See Note 2 - Acquisitions for additional information. As the indirect owner of the general partner of Delek Logistics, we have the ability to direct the activities of this entity that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes for this entity and are Delek Logistics' primary customer. In the event that Delek Logistics incurs a loss, our operating results will reflect such loss, net of intercompany eliminations, to the extent of our ownership interest in this entity. In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year. Reclassifications Certain prior period amounts have been reclassified in order to conform to the current period presentation.
