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

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Delek Delaware Gathering (formally 3 Bear) Delek Logistics completed the Delaware Gathering Acquisition on June 1, 2022 (the "Acquisition Date"), in which it acquired crude oil and natural gas gathering, processing and transportation and storage operations, as well as water disposal and recycling operations, located in the Delaware Basin of New Mexico. The purchase price for Delaware Gathering was $628.3 million. The Delaware Gathering Acquisition was financed through a combination of cash on hand and borrowings under the Delek Logistics' Revolving Facility (as discussed in Note 9 of these consolidated financial statements). For the three and six months ended June 30, 2023, we incurred no incremental direct acquisition and integration costs. For the three and six months ended June 30, 2022, we incurred $6.2 million and $6.4 million, respectively, in incremental direct acquisition and integration costs that principally consist of legal, advisory and other professional fees. Such costs are included in general and administrative expenses in the accompanying condensed consolidated statements of income for these periods. The Delaware Gathering Acquisition was accounted for using the acquisition method of accounting, whereby the purchase price was allocated to the tangible and intangible assets acquired and the liabilities assumed based on their fair values. The excess of the consideration paid over the fair value of the net assets acquired was recorded as goodwill. Determination of Purchase Price The table below represents the purchase price (in millions): Base purchase price: $ 624.7 Add: closing net working capital (as defined in the 3 Bear Purchase Agreement) 3.6 Less: closing indebtedness (as defined in the 3 Bear Purchase Agreement) (80.6) Cash paid for the adjusted purchase price 547.7 Cash paid to payoff 3 Bear credit agreement (as defined in the 3 Bear Purchase Agreement) 80.6 Purchase price $ 628.3 Purchase Price Allocation The following table summarizes the final fair values of assets acquired and liabilities assumed in the Delaware Gathering Acquisition as of June 1, 2022 (in millions): Assets acquired: Cash and cash equivalents $ 2.7 Accounts receivables, net 28.9 Inventories 1.8 Other current assets 1.0 Property, plant and equipment 382.8 Operating lease right-of-use assets 7.4 Goodwill 14.8 Other intangibles, net (1) 223.5 Other non-current assets 0.5 Total assets acquired 663.4 Liabilities assumed: Accounts payable 8.0 Accrued expenses and other current liabilities 22.4 Current portion of operating lease liabilities 1.0 Asset retirement obligations 2.3 Operating lease liabilities, net of current portion 1.4 Total liabilities assumed 35.1 Fair value of net assets acquired $ 628.3 (1) The acquired intangible assets amount includes the following identified intangibles: • Customer relationships intangible that is subject to amortization with a preliminary fair value of $210.0 million, which will be amortized over an 11.6-year useful life. • Rights-of-way intangible that is subject to amortization with a preliminary fair value of $13.5 million, which will be amortized over the weighted-average useful life of 25.4 years. The fair value of property, plant and equipment was based on the combination of the cost and market approaches. Key assumptions in the cost approach include determining the replacement cost by evaluating recently published data and adjusting replacement cost for physical deterioration, functional and economic obsolescence. We used the market approach to measure the value of certain assets through an analysis of recent sales or offerings of comparable properties. The fair value of customer relationships was based on the income approach. Key assumptions in the income approach include projected revenue attributable to customer relationships, operating margins and discount rates. The fair values discussed above were based on significant inputs that are not observable in the market and, therefore, represent Level 3 measurements. The fair values of all other current assets and liabilities were equivalent to their carrying values due to their short-term nature. The goodwill recognized in the Delaware Gathering Acquisition is primarily attributable to enhancing our third-party revenues, further diversification of our customer and product mix, expanding our footprint into the Delaware basin and bolstering our Environmental, Social and Governance ("ESG") optionality through furthering carbon capture opportunities and greenhouse gas reduction projects currently underway. This goodwill is deductible for income tax purposes. Goodwill related to the Delaware Gathering Acquisition is included in the logistics segment. Unaudited Pro Forma Financial Information The following table summarizes the unaudited pro forma financial information of the Company assuming the Delaware Gathering Acquisition had occurred on January 1, 2022. The unaudited pro forma financial information has been adjusted to give effect to certain pro forma adjustments that are directly related to the Delaware Gathering Acquisition based on available information and certain assumptions that management believes are factually supportable. The most significant pro forma adjustments relate to (i) incremental interest expense and amortization of deferred financing costs associated with revolving credit facility borrowings incurred in connection with the Delaware Gathering Acquisition, (ii) incremental depreciation resulting from the estimated fair values of acquired property, plant and equipment, (iii) incremental amortization resulting from the estimated fair values of acquired customer relationships intangible (iv) accounting policy alignment, and (v) transaction costs. The unaudited pro forma financial information excludes any expected cost savings or other synergies as a result of the Delaware Gathering Acquisition. The unaudited pro forma financial information is not necessarily indicative of the results of operations that would have been achieved had the Delaware Gathering Acquisition been effective as of the dates presented, nor is it indicative of future operating results of the combined company. Actual results may differ significantly from the unaudited pro forma financial information.

Segment Reporting [Abstract]
Segment Data	Segment Data 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. Refining Segment The refining segment processes crude oil and other feedstocks for the manufacture of transportation motor fuels, including various grades of gasoline, diesel fuel and aviation fuel, asphalt and other petroleum-based products that are distributed through owned and third-party product terminals. The refining segment has a combined nameplate capacity of 302,000 barrels per day ("bpd") as of June 30, 2023, including the following: • Tyler, Texas refinery (the "Tyler refinery"); • El Dorado, Arkansas refinery (the "El Dorado refinery"); • Big Spring, Texas refinery (the "Big Spring refinery"); and • Krotz Springs, Louisiana refinery (the "Krotz Springs refinery"). The refining segment also owns and operates three biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas, Cleburne, Texas and New Albany, Mississippi. Logistics Segment Our logistics segment owns and operates crude oil, refined products and natural gas logistics and marketing assets as well as water disposal and recycling assets. The logistics segment generates revenue by charging fees for gathering, transporting and storing crude oil and natural gas, marketing, distributing, transporting and storing intermediate and refined products and disposing and recycling water in select regions of the southeastern United States, the Delaware Basin in New Mexico and West Texas for our refining segment and third parties, and sales of wholesale products in the West Texas market. The operating results and assets acquired in the Delaware Gathering Acquisition have been included in the logistics segment since June 1, 2022. Retail Segment Our retail segment consists of 247 owned and leased convenience store sites as of June 30, 2023, located primarily in West Texas and New Mexico. These convenience stores typically offer various grades of fuel, food and beverage products, general merchandise, and certain food and other services. Substantially all of the motor fuel sold through our retail segment is supplied by our Big Spring refinery.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings Per ShareBasic earnings per share (or "EPS") is computed by dividing net income by the weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income, as adjusted for changes to income that would result from the assumed settlement of the dilutive equity instruments included in diluted weighted average common shares outstanding, by the diluted weighted average common shares outstanding. For all periods presented, we have outstanding various equity-based compensation awards that are considered in our diluted EPS calculation (when to do so would be dilutive), and is inclusive of awards disclosed in Note 16 to these condensed consolidated financial statements. For those instruments that are indexed to our common stock, they are generally dilutive when the market price of the underlying indexed share of common stock is in excess of the exercise price. The following table sets forth the computation of basic and diluted earnings per share.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Equity Method Investments Wink to Webster Pipeline Through our wholly-owned direct subsidiary Delek Energy, we own a 50% investment in W2W Holdings LLC ("HoldCo") which was formed by us and MPLX Operations LLC ("MPLX") to obtain financing and fund capital calls associated with our collective and contributed interests in the Wink to Webster Pipeline LLC ("WWP") Joint Venture. The Company has determined that HoldCo is a VIE. While we have the ability to exert significant influence through participation in board and management committees, we are not the primary beneficiary since we do not have a controlling financial interest in HoldCo, and no single party has the power to direct the activities that most significantly impact HoldCo's economic performance. We account for HoldCo using the equity method of accounting. On June 2, 2022, HoldCo's wholly-owned finance LLC ("WWP Project Financing JV") refinanced its project finance debt using the proceeds from a $535.0 million senior secured notes issuance due January 31, 2032. In connection with this notes issuance, on June 2, 2022 the WWP Project Financing JV also entered into a senior secured credit agreement that provides for revolving loan commitments in an amount of up to $75.0 million and the issuance of letters of credit in an amount of up to $44.0 million. The maturity date of the revolver and letter credit commitments is June 2, 2027. Distributions received from WWP are first applied to service the WWP Project Financing JV debt, with excess distributions being made to the HoldCo members as provided for in the W2W Holdings LLC Agreement and as allowed for under its debt agreements. The obligations of the HoldCo members under the W2W Holdings LLC Agreement are guaranteed by the parents of the member entities. As of June 30, 2023, except for the guarantee of member obligations under the joint venture, we do not have other guarantees with or to HoldCo, nor any third-party associated with HoldCo contracted work. The Company's maximum exposure to any losses incurred by HoldCo is limited to its investment. As of June 30, 2023 and December 31, 2022, Delek's HoldCo investment balance totaled $55.0 million and $49.0 million, respectively, and is included in total assets in corporate, other and eliminations in our segment disclosure. In addition, on the investment, we recognized income of $6.8 million and $11.3 million for the three and six months ended June 30, 2023, respectively, and $2.1 million and $4.2 million for the three and six months ended June 30, 2022, respectively. Delek Logistics Investments Delek Logistics has a 33% membership interest in Red River Pipeline Company LLC (“Red River”), which owns a 16-inch crude oil pipeline running from Cushing, Oklahoma to Longview, Texas. As of June 30, 2023 and December 31, 2022, Delek's investment balance in Red River totaled $140.9 million and $149.6 million, respectively. We recognized income on the investment totaling $4.0 million and $7.8 million for the three and six months ended June 30, 2023, respectively, and $4.6 million and $9.9 million for the three and six months ended June 30, 2022, respectively. This investment is accounted for using the equity method and is included as part of total assets in our logistics segment. In addition to Red River, Delek Logistics has two other joint ventures that own and operate logistics assets, and which serve third parties and subsidiaries of Delek. We own a 50% membership interest in the entity formed with an affiliate of Plains All American Pipeline, L.P. to operate one of these pipeline systems (the "Caddo Pipeline") and a 33% membership interest in Andeavor Logistics Rio Pipeline LLC which operates the other pipeline system (the "Rio Pipeline"). As of June 30, 2023 and December 31, 2022, Delek Logistics' investment balance in these joint ventures was $101.8 million and $107.4 million, respectively, and are accounted for using the equity method. We recognized income on these investments totaling $3.3 million and $5.8 million for the three and six months ended June 30, 2023, respectively, and $2.4 million and $4.2 million for the three and six months ended June 30, 2022, respectively. Other Investments In addition to our pipeline joint ventures, we also have a 50% interest in a joint venture that owns asphalt terminals located in the southwestern region of the U.S., as well as a 50% interest in a joint venture that owns, operates and maintains a terminal consisting of an ethanol unit train facility with an ethanol tank in Arkansas. As of June 30, 2023 and December 31, 2022, Delek's investment balance in these joint ventures was $65.9 million and $53.7 million, respectively. We recognized income on these investments totaling $11.4 million and $15.2 million for the three and six months ended June 30, 2023, respectively, and $6.6 million and $8.3 million for the three and six months ended June 30, 2022, respectively.

In addition to the cost of financing charges, we have other intermediation fees which include market structure settlements, where we may pay or receive amounts based on market conditions and volumes subject to the intermediation agreement. These market structure settlements are recorded in cost of materials and other in the condensed consolidated statements of income. The following table summarizes these fees: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Net fees and expenses: Inventory intermediation fees $ 7.6 $ 18.6 $ 13.5 $ 37.7 Interest expense, net $ 15.6 $ 5.2 $ 29.6 $ 10.2 Inventory Intermediation Agreement On December 22, 2022, Delek entered into an inventory intermediation agreement ("Inventory Intermediation Agreement") with Citigroup Energy Inc. ("Citi") in connection with DK Trading & Supply, LLC ("DKTS"), an indirect subsidiary of Delek. Pursuant to the Inventory Intermediation Agreement, Citi will (i) purchase from and sell to DKTS crude oil and other petroleum feedstocks in connection with refining processing operations at El Dorado, Big Spring, and Krotz Springs, (ii) purchase from and sell to DKTS all refined products produced by such refineries other than certain excluded products and (iii) in connection with such purchases and sales, DKTS will enter into certain market risk hedges in each case, on the terms and subject to certain conditions. The Inventory Intermediation Agreement results in up to $800 million of working capital capacity for DKTS. The Inventory Intermediation Agreement expires December 30, 2024, subject to an extension that can be executed by Citi for an additional twelve months. Prior to December 30, 2022, Delek had Supply and Offtake Agreements (the "Supply and Offtake Agreements" or the "J. Aron Agreements") with J. Aron & Company ("J. Aron"). The Inventory Intermediation Agreement replaced the Supply and Offtake Agreements that expired on December 30, 2022. On June 21, 2023, DKTS entered into a letter agreement to the Inventory Intermediation Agreement with Citi to temporarily increase its letter of credit issued to Citi by $100.0 million which will allow DKTS to defer payments of certain obligations under the Inventory Intermediation Agreement until July 2023. These deferred obligations will be subject to applicable interest charges. As of June 30, 2023, we had letters of credit outstanding of $195.0 million supporting the Inventory Intermediation Agreement. The Inventory Intermediation Agreement provides for the lease to Citi of crude oil and refined product storage facilities. At the inception of the Inventory Intermediation Agreement, we transferred title to a certain number of barrels of crude and other inventories to Citi, and the Inventory Intermediation Agreement requires the repurchase of the remaining inventory (including certain "Base Layer Volumes") at termination. As of June 30, 2023 and December 31, 2022, the volumes subject to the Inventory Intermediation Agreement totaled 5.8 million barrels and 6.3 million barrels, including Base Layer Volumes associated with our non-current inventory intermediation obligation of 5.5 million barrels. The Inventory Intermediation Agreement is accounted for as an inventory financing arrangement under the fair value election provided by ASC 815 Derivatives and Hedging ("ASC 815") and ASC 825, Financial Instruments ("ASC 825"). Therefore, the crude oil and refined products barrels subject to the Inventory Intermediation Agreement will continue to be reported in our condensed consolidated balance sheets until processed and sold to a third party. At each reporting period, we record a liability equal to the repurchase obligation to Citi at current market prices. The repurchase obligations associated with the Base Layer Volumes are reflected as non-current liabilities on our condensed consolidated balance sheet to the extent that they are not contractually due within twelve months. The remaining obligation resulting from our monthly activity, including long and short inventory positions valued at market-indexed pricing, are included in current liabilities (or receivables) on our condensed consolidated balance sheet. Gains (losses) related to changes in fair value due to commodity-index price are recorded as a component of cost of materials and other in the condensed consolidated statements of income. With respect to the repurchase obligation, we recognized gains attributable to changes in fair value due to commodity-index price totaling $26.3 million and $39.0 million during the three and six months ended June 30, 2023, respectively. Supply & Offtake Agreements Prior to December 30, 2022, Delek was a party to Supply and Offtake Agreements with J. Aron in connection with its El Dorado, Big Spring and Krotz Springs refineries. Pursuant to the Supply and Offtake Agreements, (i) J. Aron agreed to sell to us, and we agreed to buy from J. Aron, at market prices, crude oil for processing at these refineries and (ii) we agreed to sell, and J. Aron agreed to buy, at market prices, certain refined products produced at these refineries. The repurchase of Baseline Volumes at the end of the Supply and Offtake Agreement term (representing the "Baseline Step-Out Liability" or, collectively, the "Baseline Step-Out Liabilities") continued to be recorded at fair value under the fair value election included under ASC 815 and ASC 825. The Baseline Step-Out Liabilities had a floating component whose fair value reflected changes to commodity price risk with changes in fair value recorded in cost of materials. For the three and six months ended June 30, 2022, we recognized gains in cost of materials and other attributable to changes in fair value due to commodity-index price totaling $58.1 million and $206.9 million, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments We use the majority of our derivatives to reduce normal operating and market risks with the primary objective of reducing the impact of market price volatility on our results of operations. As such, our use of derivative contracts is aimed at: • limiting our exposure to commodity price fluctuations on inventory above or below target levels (where appropriate) within each of our segments; • managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks/intermediates and finished grade fuel within each of our segments; • managing our exposure to market crack spread fluctuations; • managing the cost of our credits required by the U.S. Environmental Protection Agency ("EPA") to blend biofuels into fuel products ("RINs Obligation") using future commitments to purchase or sell RINs at fixed prices and quantities; and • limiting the exposure to interest rate fluctuations on our floating rate borrowings. We primarily utilize commodity swaps, futures, forward contracts and options contracts, generally with maturity dates of three years or less, and from time to time interest rate swaps or caps to achieve these objectives. Futures contracts are standardized agreements, traded on a futures exchange, to buy or sell the commodity at a predetermined price and location at a specified future date. Options provide the right, but not the obligation to buy or sell a commodity at a specified price in the future. Commodity swaps and futures contracts require cash settlement for the commodity based on the difference between a fixed or floating price and the market price on the settlement date, and options require payment/receipt of an upfront premium. Because these derivatives are entered into to achieve objectives specifically related to our inventory and production risks, such gains and losses (to the extent not designated as accounting hedges and recognized on an unrealized basis in other comprehensive income) are recognized in cost of materials and other. Forward contracts are agreements to buy or sell a commodity at a predetermined price at a specified future date, and for our transactions, generally require physical delivery. Forward contracts where the underlying commodity will be used or sold in the normal course of business qualify as normal purchases and normal sales ("NPNS") pursuant to ASC 815. If we elect the NPNS exception, such forward contracts are not accounted for as derivative instruments but rather are accounted for under other applicable GAAP. Commodity forward contracts accounted for as derivative instruments are recorded at fair value with changes in fair value recognized in earnings in the period of change. Our Canadian crude trading operations are accounted for as derivative instruments, and the related unrealized and realized gains and losses are recognized in other operating income, net on the condensed consolidated statements of income. Additionally, as of and for the three and six months ended June 30, 2023, other forward contracts accounted for as derivatives that are specific to managing crude costs rather than for trading purposes are recognized in cost of materials and other on the condensed consolidated statements of income in our refining segment, and are included in our disclosures of commodity derivatives in the tables below. Futures, swaps or other commodity related derivative instruments that are utilized to specifically provide economic hedges on our Canadian forward contract or investment positions are recognized in other operating income, net because that is where the related underlying transactions are reflected. From time to time, we also enter into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs Obligation. These future RINs commitment contracts meet the definition of derivative instruments under ASC 815, and are recorded at estimated fair value in accordance with the provisions of ASC 815. Changes in the fair value of these future RINs commitment contracts are recorded in cost of materials and other on the condensed consolidated statements of income. As of June 30, 2023, we do not believe there is any material credit risk with respect to the counterparties to any of our derivative contracts. The following table presents the fair value of our derivative instruments as of June 30, 2023 and December 31, 2022. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under our master netting arrangements, including cash collateral on deposit with our counterparties. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements. As a result, the asset and liability amounts below differ from the amounts presented in our condensed consolidated balance sheets.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Our assets and liabilities that are measured at fair value include commodity derivatives, investment commodities, environmental credits obligations, our Inventory Intermediation Agreement, and Supply and Offtake Agreements. ASC 820, Fair Value Measurements ("ASC 820"), requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants. Our commodity derivative contracts, which consist of commodity swaps, exchange-traded futures, options and physical commodity forward purchase and sale contracts (that do not qualify for the NPNS exception under ASC 815), are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2. To the extent that we have purchased RINs or transferred RINs to our refineries, each refinery’s RINs Obligation may be a surplus or deficit at the end of each reporting period (their respective “Net RINs Obligation”). Because our Net RINs Obligations exceed the RINs we are able to generate annually on a consolidated basis, and because we have the legal ability to transfer RINs generated or purchased through any of our entities to our obligated parties as needed, we view and manage the Company’s individual Net RINs Obligations, as well as any non-obligated party RINs holdings, on a consolidated basis. Therefore, the sum of our individual obligated parties’ Net RINs Obligations as well as RINs held by our non-obligated parties which meet our recognition criteria, comprises the Company’s “Consolidated Net RINs Obligation.” Our RINs commitment contracts are future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our Consolidated Net RINs Obligation. These RINs commitment contracts (which are forward contracts accounted for as derivatives – see Note 10) are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service. Our environmental credits obligation surplus or deficit includes the Consolidated Net RINs Obligation surplus or deficit, as well as other environmental credit obligation surplus or deficit positions subject to fair value accounting pursuant to our accounting policy. The environmental credits obligation surplus or deficit is categorized as Level 2, if measured at fair value either directly through observable inputs or indirectly through market-corroborated inputs, and gains (losses) related to changes in fair value are recorded as a component of cost of materials and other in the consolidated statements of income. With respect to our Consolidated Net RINs Obligation surplus or deficit, we recognized gains (losses) on changes in fair value totaling $(2.1) million and $(1.8) million for the three and six months ended June 30, 2023, respectively, and $(39.8) million and $(41.0) million for the three and six months ended June 30, 2022, respectively, primarily attributable to changes in the market prices of the underlying credits that occurred at the end of each quarter. As of and for the three and six months ended June 30, 2023 and 2022, we elected to account for our Inventory Intermediation step-out liability and our J. Aron step-out liability at fair value in accordance with ASC 825, as it pertains to the fair value option. This standard permits the election to carry financial instruments and certain other items similar to financial instruments at fair value on the balance sheet, with all changes in fair value reported in earnings. With respect to the Inventory Intermediation Agreement and the amended and restated Supply and Offtake Agreements, we apply fair value measurement as follows: (1) we determine fair value for our amended variable step-out liability based on changes in fair value related to market volatility based on a floating commodity-index price, and for our amended fixed step-out liability based on changes to interest rates and the timing and amount of expected future cash settlements where such obligation is categorized as Level 2. Gains (losses) related to changes in fair value due to commodity-index price are recorded as a component of cost of materials and other, and changes in fair value due to interest rate risk are recorded as a component of interest expense in the condensed consolidated statements of income; and (2) we determine fair value of the commodity-indexed revolving over/short inventory financing liability based on the market prices for the consigned crude oil and refined products collateralizing the financing/funding where such obligation is categorized as Level 2 and is presented in the current portion of the Obligation under Inventory Intermediation Agreement on our condensed consolidated balance sheets. Gains (losses) related to the change in fair value are recorded as a component of cost of materials and other in the consolidated statements of income. See Note 8 for discussion of gains and losses recognized from changes in fair value. The fair value of the Delek Logistics 2028 Notes is measured based on quoted market prices in an active market, defined as Level 1 in the fair value hierarchy. The carrying value (excluding unamortized debt issuance costs) and estimated fair value of these notes was $400.0 million and $372.1 million, respectively, as of June 30, 2023, and $400.0 million and $359.7 million, respectively, at December 31, 2022. The fair value approximates the historical or amortized cost basis comprising our carrying value for all other financial instruments and therefore are not included in the table below. The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis was as follows (in millions): As of June 30, 2023 Level 1 Level 2 Level 3 Total Assets Commodity derivatives $ — $ 182.8 $ — $ 182.8 RINs commitment contracts — 3.0 — 3.0 Total assets — 185.8 — 185.8 Liabilities Commodity derivatives — (174.0) — (174.0) RINs commitment contracts — (3.9) — (3.9) Environmental credits obligation deficit — (76.2) — (76.2) Inventory Intermediation Agreement obligation — (453.4) — (453.4) Total liabilities — (707.5) — (707.5) Net liabilities $ — $ (521.7) $ — $ (521.7) As of December 31, 2022 Level 1 Level 2 Level 3 Total Assets Commodity derivatives $ — $ 319.2 $ — $ 319.2 RINs commitment contracts — 9.7 — 9.7 Total assets — 328.9 — 328.9 Liabilities Commodity derivatives — (334.7) — (334.7) RINs commitment contracts — (6.6) — (6.6) Environmental credits obligation deficit — (295.5) — (295.5) Inventory Intermediation Agreement obligation — (541.7) — (541.7) Total liabilities — (1,178.5) — (1,178.5) Net liabilities $ — $ (849.6) $ — $ (849.6) The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. In the table above, derivative assets and liabilities with the same counterparty are not netted where the legal right of offset exists. This differs from the presentation in the financial statements which reflects our policy, wherein we have elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and where the legal right of offset exists. As of June 30, 2023 and December 31, 2022, $12.9 million and $13.8 million, respectively, of cash (obligation) collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty. See Note 10 for further information regarding derivative instruments. Non-Recurring Fair Value Measurements The Delaware Gathering Acquisition was accounted for as a business combination using the acquisition method of accounting, with the assets acquired and liabilities assumed at their respective acquisition date fair values at the closing date. The fair value measurements were based on a combination of valuation methods including discounted cash flows, the market approach and obsolescence adjusted replacement costs, all of which are Level 3 inputs.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In the ordinary conduct of our business, we are from time to time subject to lawsuits, investigations and claims, including environmental claims and employee-related matters. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, including civil penalties or other enforcement actions, we do not believe that any currently pending legal proceeding or proceedings to which we are a party will have a material adverse effect on our financial statements. Certain environmental matters that have or may result in penalties or assessments are discussed below in the "Environmental, Health and Safety" section of this note. Environmental, Health and Safety We are subject to extensive federal, state and local environmental and safety laws and regulations enforced by various agencies, including the EPA, the United States Department of Transportation and the Occupational Safety and Health Administration, as well as numerous state, regional and local environmental, safety and pipeline agencies. These laws and regulations govern the discharge of materials into the environment, waste management practices, pollution prevention measures and the composition of the fuels we produce, as well as the safe operation of our plants and pipelines and the safety of our workers and the public. Numerous permits or other authorizations are required under these laws and regulations for the operation of our refineries, renewable fuels facilities, terminals, pipelines, underground storage tanks, trucks, rail cars and related operations, and may be subject to revocation, modification and renewal. These laws and permits raise potential exposure to future claims and lawsuits involving environmental and safety matters which could include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including notices of violations, citations and other enforcement actions, some of which have resulted or may result in changes to operating procedures and in capital expenditures. While it is often difficult to quantify future environmental or safety related expenditures, we anticipate that continuing capital investments and changes in operating procedures will be required for the foreseeable future to comply with existing and new requirements, as well as evolving interpretations and more strict enforcement of existing laws and regulations. As of June 30, 2023, we have recorded an environmental liability of approximately $114.7 million, primarily related to the estimated probable costs of remediating or otherwise addressing certain environmental issues of a non-capital nature at our refineries, as well as terminals, some of which we no longer own. This liability includes estimated costs for ongoing investigation and remediation efforts for known contamination of soil and groundwater. Approximately $3.1 million of the total liability is expected to be expended over the next 12 months, with most of the balance expended by 2032, although some costs may extend up to 30 years. In the future, we could be required to extend the expected remediation period or undertake additional investigations of our refineries, pipelines and terminal facilities, which could result in the recognition of additional remediation liabilities. Included in our environmental liabilities as of both June 30, 2023 and December 31, 2022 is a liability totaling $78.5 million related to a property that we have historically operated as an asphalt and marine fuel terminal both as an owner and, subsequently, as a lessee under an in-substance lease agreement (the “License Agreement”). The License Agreement, which provided us the license to continue operating our asphalt and marine fuel terminal operations on the property for a term of ten years and expired in June 2020, also ascribed a contractual noncontingent indemnification guarantee to certain of our wholly-owned subsidiaries related to certain incremental environmental remediation activities, predicated on the completion of certain property development activities ascribed to the lessor. Our combined liability, comprised of our environmental liability plus the estimated fair value of the noncontingent guarantee liability, was recorded in connection with the Delek/Alon Merger, effective July 1, 2017. While the License Agreement expired in June 2020, it is currently being disputed in litigation where we have determined that no loss accrual is necessary and that the amount of incremental loss that is reasonably possible is immaterial as of June 30, 2023. Such ongoing dispute causes sufficient uncertainty around the release of risk and the appropriate joint and several liability allocations thereunder that we cannot currently determine a more reasonable estimate of the potential total contingent liability that is probable, nor do we have sufficient information to better estimate the fair value of any remaining noncontingent guarantee liability. As such, as of June 30, 2023 and December 31, 2022, except for accretion and expenditures, our combined environmental liability related to the terminal and property remained unchanged. We are also subject to various regulatory requirements related to carbon emissions and the compliance requirements to remit environmental credit obligations due to the EPA or other regulatory agencies, the most significant of which relates to the RINs Obligation subject to the EPA’s RFS-2 regulations. The RFS-2 regulations are highly complex and evolving, requiring us to periodically update our compliance systems. As part of our on-going monitoring and compliance efforts, on an annual basis we engage a third party to perform procedures to review our RINs inventory, processes and compliance. The results of such procedures may include procedural findings but may also include findings regarding the usage of RINs to meet past obligations, the treatment of exported RINs, and the propriety of RINs on-hand and related adjustments to our RINs inventory, which (to the extent they are valued) offset our RINs Obligation. Such adjustments may also require communication with the EPA if they involve reportable non-compliance which could lead to the assessment of penalties. Other Losses and Contingencies Delek maintains property damage insurance policies which have varying deductibles. Delek also maintains business interruption insurance policies, with varying coverage limits and waiting periods. Covered losses in excess of the deductible and outside of the waiting period will be recoverable under the property and business interruption insurance policies. El Dorado Refinery Fire On February 27, 2021, our El Dorado refinery experienced a fire in its Penex unit. Contrary to initial assessments, and despite occurring during the early stages of turnaround activity, the facility suffered operational disruptions as a result of the fire. We recognized a gain of $0.9 million and $0.9 million during the three and six months ended June 30, 2023, respectively, and a gain of $3.3 million and $7.6 million during the three and six months ended June 30, 2022, respectively, related to business interruption claims. This gain is included in other operating income in the condensed consolidated statements of income. If applicable, we accrue receivables for probable insurance or other third-party recoveries. Work to determine the full extent of covered business interruption and property and casualty losses and potential insurance claims is ongoing and may result in the future recognition of insurance recoveries. Big Spring Refinery Fire On November 29, 2022, our Big Spring refinery experienced a fire in its diesel hydrotreater unit. The facility suffered operational disruptions as a result of the fire. Accelerated depreciation due to property damaged in the fire was immaterial. We incurred repair costs that may be recoverable under property and casualty insurance policies and we submitted a claim in 2023. If applicable, we accrue receivables for probable insurance or other third-party recoveries. Work to determine the full extent of covered property losses and potential insurance claims is ongoing and may result in the future recognition of insurance recoveries. Winter Storm Uri

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Under ASC 740, Income Taxes (“ASC 740”) we used an estimated annual tax rate to record income taxes for the three and six months ended June 30, 2023 and June 30, 2022. Our effective tax rate was 71.7% and 14.5% for the three and six months ended June 30, 2023, respectively, and 21.4% and 21.3% for the three and six months ended June 30, 2022, respectively. The difference between the effective tax rate and the statutory rate is generally attributable to permanent differences and discrete items. The change in our effective tax rate for the three and six months ended June 30, 2023 as compared to the three and six months ended June 30, 2022 was primarily due to a decrease in pre-tax earnings and the impact fixed dollar favorable permanent differences on the tax rate, and changes in the second quarter estimated annual effective tax rate applied to year to date earnings.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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.

Business Acquisition, Pro Forma Information	The following table summarizes the unaudited pro forma financial information of the Company assuming the Delaware Gathering Acquisition had occurred on January 1, 2022. The unaudited pro forma financial information has been adjusted to give effect to certain pro forma adjustments that are directly related to the Delaware Gathering Acquisition based on available information and certain assumptions that management believes are factually supportable. The most significant pro forma adjustments relate to (i) incremental interest expense and amortization of deferred financing costs associated with revolving credit facility borrowings incurred in connection with the Delaware Gathering Acquisition, (ii) incremental depreciation resulting from the estimated fair values of acquired property, plant and equipment, (iii) incremental amortization resulting from the estimated fair values of acquired customer relationships intangible (iv) accounting policy alignment, and (v) transaction costs. The unaudited pro forma financial information excludes any expected cost savings or other synergies as a result of the Delaware Gathering Acquisition. The unaudited pro forma financial information is not necessarily indicative of the results of operations that would have been achieved had the Delaware Gathering Acquisition been effective as of the dates presented, nor is it indicative of future operating results of the combined company.
