Basis of Presentation	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.
Variable Interest Entities	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.
Consolidation, Policy	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.
Reclassification	Certain prior period amounts have been reclassified in order to conform to the current period presentation.
Segment Reporting	We aggregate our operating units into three reportable segments: Refining, Logistics, and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consist of the following: •our corporate activities; •results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 10); and •intercompany eliminations. During the fourth quarter 2022, we realigned our reportable segments for financial reporting purposes to reflect changes in the manner in which our chief operating decision maker, or CODM, assesses financial information for decision-making purposes. The change primarily represents reporting the operating results of wholesale crude operations within the refining segment. Prior to this change, wholesale crude operations were reported as part of corporate, other and eliminations. While this reporting change did not change our consolidated results, segment data for previous years has been restated and is consistent with the current year presentation throughout the financial statements and the accompanying notes. The disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The CODM evaluates performance based upon EBITDA attributable to Delek. We define EBITDA attributable to Delek for any period as net income (loss) attributable to Delek plus interest expense, income tax expense (benefit), depreciation and amortization. Segment EBITDA should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered alternatives to net income (loss), which is the most directly comparable financial measure to EBITDA that is in accordance with U.S. GAAP. Segment EBITDA, as determined and measured by us, should also not be compared to similarly titled measures reported by other companies. Assets by segment are not a measure used to assess the performance of the Company by the CODM and thus are not disclosed.
Inventory	Crude oil feedstocks, refined products, blendstocks and asphalt inventory for all of our operations, excluding merchandise inventory in our retail segment, are stated at the lower of cost determined using the first-in, first-out ("FIFO") basis or net realizable value. Retail merchandise inventory consists of cigarettes, beer, convenience merchandise and food service merchandise and is stated at estimated cost as determined by the retail inventory method.

Variable Interest Entities

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").

Consolidation, Policy

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.

Reclassification

Certain prior period amounts have been reclassified in order to conform to the current period presentation.

Segment Reporting

We aggregate our operating units into three reportable segments: Refining, Logistics, and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consist of the following:

•our corporate activities;

•results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 10); and

•intercompany eliminations.

During the fourth quarter 2022, we realigned our reportable segments for financial reporting purposes to reflect changes in the manner in which our chief operating decision maker, or CODM, assesses financial information for decision-making purposes. The change primarily represents reporting the operating results of wholesale crude operations within the refining segment. Prior to this change, wholesale crude operations were reported as part of corporate, other and eliminations. While this reporting change did not change our consolidated results, segment data for previous years has been restated and is consistent with the current year presentation throughout the financial statements and the accompanying notes.

The disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The CODM evaluates performance based upon EBITDA attributable to Delek. We define EBITDA attributable to Delek for any period as net income (loss) attributable to Delek plus interest expense, income tax expense (benefit), depreciation and amortization. Segment EBITDA should not be considered a substitute for results prepared in accordance with U.S. GAAP and should not be considered alternatives to net income (loss), which is the most directly comparable financial measure to EBITDA that is in accordance with U.S. GAAP. Segment EBITDA, as determined and measured by us, should also not be compared to similarly titled measures reported by other companies.

Assets by segment are not a measure used to assess the performance of the Company by the CODM and thus are not disclosed.

Inventory

Crude oil feedstocks, refined products, blendstocks and asphalt inventory for all of our operations, excluding merchandise inventory in our retail segment, are stated at the lower of cost determined using the first-in, first-out ("FIFO") basis or net realizable value. Retail merchandise inventory consists of cigarettes, beer, convenience merchandise and food service merchandise and is stated at estimated cost as determined by the retail inventory method.
