Notes to Consolidated Financial Statements

Delek US Holdings, Inc.

Notes to Condensed Consolidated Financial Statements (unaudited)

1. 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 February 28, 2024 (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, 2023 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"). 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.

Accounting Pronouncements Not Yet Adopted

ASU 2023-09, Income Taxes(Topic 740): Improvements to Income Tax Disclosures

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 Income Taxes(Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). The standard is intended to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The amendments in this ASU are effective for annual periods beginning after December 15, 2024, with early adoption permitted, and should be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the provisions of the amendments and the impact on its future condensed consolidated financial statements, but does not currently expect adopting this new guidance will have a material impact on our condensed consolidated financial statements and related disclosures.

ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the chief decision maker ("CODM") and included within each reported measure of a segment's profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and should be applied retrospectively to all prior periods presented in the financial statements. The adoption of ASU 2023-07 should not have a material impact on our condensed consolidated financial statements and related disclosures. See Note 2 for further information.

Notes to Consolidated Financial Statements

ASU 2023-06, Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative

In October 2023, the FASB issued ASU 2023-06 Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative ("ASU 2023-06"). The main provision of ASU 2023-06 is to clarify or improve disclosure and presentation requirements of a variety of topics, which will allow users to more easily compare entities subject to the SEC's existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the FASB accounting standard codification with the SEC's regulations. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is currently evaluating the provisions of the amendments and the impact on its future condensed consolidated financial statements, but does not currently expect adopting this new guidance will have a material impact on our condensed consolidated financial statements and related disclosures.

2. 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 9); and

•intercompany eliminations.

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 includes 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. In addition, the refining segment includes our wholesale crude operations.

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.

Retail Segment

Our retail segment consists of 250 owned and leased convenience store sites as of March 31, 2024, 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, which is transferred to the retail segment at prices substantially determined by reference to published commodity pricing information.

Business Segment Operating Performance

The following is a summary of business segment operating performance as measured by EBITDA attributable to Delek for the period indicated (in millions):

3. Earnings Per Share

Basic earnings per share (or "EPS") is computed by dividing net income (loss) 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 15 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.

4. Delek Logistics

Delek Logistics is a publicly traded limited partnership formed by Delek in 2012 that owns and operates crude oil, refined products and natural gas logistics and marketing assets as well as water disposal and recycling assets. A substantial majority of Delek Logistics' assets are integral to Delek’s refining and marketing operations. As of March 31, 2024, we owned a 72.7% interest in Delek Logistics, consisting of 34,311,278 common limited partner units and the non-economic general partner interest. The limited partner interests in Delek Logistics not owned by us are reflected in net income attributable to non-controlling interest in the accompanying condensed consolidated statements of income and in non-controlling interest in subsidiaries in the accompanying condensed consolidated balance sheets.

On March 12, 2024, Delek Logistics completed a public offering of its common units in which it sold 3,584,416 common units (including an overallotment option of 467,532 common units) to the underwriters of the offering at a price to the public of $38.50 per unit. The proceeds received from this offering (net of underwriting discounts, commissions and expenses) were $132.3 million and were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility (defined below). Underwriting discounts totaled $5.5 million.

As a result of this common unit issuance and our resulting Delek Logistics ownership change, we adjusted additional paid-in capital and equity attributable to Delek Logistics’ non-controlling interest holders to reallocate Delek Logistics' equity among its unitholders.

Delek Logistics is a VIE, as defined under GAAP, and is consolidated into our condensed consolidated financial statements, representing our logistics segment. The assets of Delek Logistics can only be used to settle its own obligations and its creditors have no recourse to our assets. Exclusive of intercompany balances and the marketing agreement intangible asset between Delek Logistics and Delek which are eliminated in consolidation, the Delek Logistics condensed consolidated balance sheets are included in the condensed consolidated balance sheets of Delek. The Delek Logistics condensed consolidated balance sheets are presented below (in millions):

5. 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.

Distributions received from WWP are first applied to service the debt of HoldCo's wholly owned finance LLC, 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 March 31, 2024, 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 March 31, 2024 and December 31, 2023, Delek's HoldCo investment balance totaled $60.8 million and $51.4 million, 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 March 31, 2024 and December 31, 2023, Delek's investment balance in Red River totaled $140.0 million and $141.1 million, respectively.

In addition to Red River, Delek Logistics has two other pipeline joint ventures in which 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 and a 33% membership interest in Andeavor Logistics Rio Pipeline LLC which operates the other pipeline system. As of March 31, 2024 and December 31, 2023, Delek Logistics' investment balance in these joint ventures was $98.2 million and $100.3 million.

As of March 31, 2024 and December 31, 2023, Delek's investment balance in these joint ventures was $71.3 million and $67.9 million, respectively.

6. 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.

Included in the Inventory Intermediation Agreement are cost of financing associated with the value of the inventory and other periodic charges, which we include in interest expense, net in the condensed consolidated statements of income. 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:

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.

On December 21, 2023, DKTS amended the Inventory Intermediation Agreement to among other things, (i) extend the term of the Inventory Intermediation Agreement from December 30, 2024 to January 31, 2026, (ii) reduce Citi’s unilateral term extension option from a twelve month extension period to a six month extension period and (iii) increase the amount of the payment deferral mechanism from $70 million to $250 million. As of March 31, 2024 and December 31, 2023, we had letters of credit outstanding of $185.0 million and $230.0 million, respectively, 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 March 31, 2024 and December 31, 2023, the volumes subject to the Inventory Intermediation Agreement totaled 5.5 million barrels and 5.4 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 Accounting Standards Codification ("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 sheets 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 sheets.

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 losses attributable to changes in fair value due to commodity-index price totaling $81.8 million and gains totaling $12.7 million during the three months ended March 31, 2024 and 2023, respectively.

Delek Logistics 2029 Notes

On March 13, 2024, Delek Logistics and its wholly owned subsidiary Delek Logistics Finance Corp. (“Finance Corp.” and together with Delek Logistics, the “Co-issuers”), sold $650.0 million in aggregate principal amount of the Co-issuers 8.625% Senior Notes due 2029 (the “Delek Logistics 2029 Notes”), at par, pursuant to an indenture with U.S. Bank Trust Company, National Association as trustee. Net proceeds were used to redeem the Delek Logistics 2025 Notes including accrued interest, pay off the Delek Logistics Term Loan Facility including accrued interest and to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

On April 17, 2024, the Co-issuers sold $200.0 million in aggregate principal amount of additional 8.625% senior notes due 2029 (the “Additional 2029 Notes”), at 101.25%.

The net proceeds were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

The Delek Logistics 2029 Notes are general unsecured senior obligations of the Co-issuers and are unconditionally guaranteed jointly and severally on a senior unsecured basis by Delek Logistics’ subsidiaries other than Finance Corp. and will be unconditionally guaranteed on the same basis by certain of Delek Logistics’ future subsidiaries. The Delek Logistics 2029 Notes rank equal in right of payment with all existing and future senior indebtedness of the Co-issuers, and senior in right of payment to any future subordinated indebtedness of the Co-issuers.

Notes to Consolidated Financial Statements

The obligations under the Delek Logistics Revolving Facility are secured by first priority liens on substantially all of Delek Logistics' tangible and intangible assets.

Restrictive Terms and Covenants

Under the terms of our debt facilities, we are required to comply with usual and customary financial and non-financial covenants. Certain of our debt facilities contain limitations on future transactions such as incurrence of additional indebtedness, investments, affiliate transactions, asset acquisitions or dispositions, and dividends or distributions. As of March 31, 2024, we were in compliance with covenants on all of our debt instruments.

Some of Delek's subsidiaries have restrictions in their respective credit facilities limiting their use of assets. As of March 31, 2024, we had no subsidiaries with restricted net assets which would prohibit earnings from being transferred to the parent company for its use.

9. 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 Renewable Identification Numbers ("RINs") 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 months ended March 31, 2024, 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 March 31, 2024, 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 March 31, 2024 and December 31, 2023. 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. See Note 10 for further information regarding the fair value of derivative instruments (in millions).

10. Fair Value Measurements

Our assets and liabilities that are measured at fair value include commodity derivatives, investment commodities, environmental credits obligations, and our Inventory Intermediation Agreement. 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.

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 9) are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service.

Our environmental credits obligation includes the Consolidated Net RINs Obligation, as well as other environmental credit obligation positions subject to fair value accounting pursuant to our accounting policy. The environmental credits obligation 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 condensed consolidated statements of income. With respect to our Consolidated Net RINs Obligation, we recognized no gain on changes in fair value for the three months ended March 31, 2024 and a gain totaling $0.3 million for the three months ended March 31, 2023, primarily attributable to changes in the market prices of the underlying credits that occurred at the end of each quarter.

We elected to account for our Inventory Intermediation 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, 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 condensed consolidated statements of income. See Note 7 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 $391.4 million, respectively, as of March 31, 2024, and $400.0 million and $380.4 million, respectively, at December 31, 2023.

Also, the fair value of the Delek Logistics 2029 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 $650.0 million and $664.3 million, respectively, as of March 31, 2024.

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 March 31, 2024 and December 31, 2023, $5.7 million and $1.8 million, respectively, of cash collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty. See Note 9 for further information regarding derivative instruments.

11. 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.

20 |

Notes to Consolidated Financial Statements

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 U.S. 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 March 31, 2024, we have recorded an environmental liability of approximately $113.4 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 $2.9 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 March 31, 2024 and December 31, 2023 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 March 31, 2024. 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 March 31, 2024 and December 31, 2023, 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 Renewable Fuel Standard - 2 ("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.

12. Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), we generally use an estimated annual tax rate to record income taxes. For interim financial reporting, except in specified cases, the quarterly income tax provision aligns with the estimated annual tax rate, updated each quarter based on revised full-year pre-tax book earnings. In certain situations, the estimated annual tax rate may distort the interim income tax provision due to significant permanent differences. In such cases, the interim income tax provision is based on the year-to-date effective tax rate, adjusting for permanent differences proportionally. In the three months ended March 31, 2024, income taxes were calculated based on the year-to-date effective tax rate. In the three months ended March 31, 2023, income taxes were calculated based on the estimated annual tax rate. Our effective tax rate was 22.2% and 18.0% for the three months ended March 31, 2024 and 2023, 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 months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily due to an decrease in quarter to date pre-tax earnings and the impact of fixed dollar favorable permanent adjustments on the quarter when applying a year-to-date effective tax rate.

13. Related Party Transactions

Our related party transactions consist primarily of transactions with our equity method investees (See Note 5). Transactions with our related parties were as follows for the periods presented (in millions):

	Three Months Ended March 31,
	2024		2023
Revenues (1)	$	22.0	$	17.9

15. Equity-Based Compensation

Delek US Holdings, Inc. 2006 and 2016 and Alon USA Energy, Inc. 2005 Long-Term Incentive Plans (collectively, the "Incentive Plans")

Compensation expense related to equity-based awards granted under the Incentive Plans amounted to $6.3 million and $5.9 million for the three months ended March 31, 2024 and 2023, respectively. These amounts are included in general and administrative expenses and operating expenses in the accompanying condensed consolidated statements of income. As of March 31, 2024, there was $42.7 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.5 years.

We issued net shares of common stock of 44,374 and 53,643 as a result of exercised or vested equity-based awards during the three months ended March 31, 2024 and 2023, respectively. These amounts are net of 35,434 and 20,463 shares withheld to satisfy employee tax obligations related to the exercises and vesting during the three months ended March 31, 2024 and 2023, respectively.

16.  Shareholders' Equity

Stock Repurchase Program

Our Board of Directors has authorized a share repurchase program under which repurchases of Delek common stock may be executed through open market transactions or privately negotiated transactions, in accordance with applicable securities laws. The timing, price and size of repurchases are made at the discretion of management and will depend on prevailing share prices, general economic and market conditions and other considerations. The authorization has no expiration date. During the three months ended March 31, 2023, 16,292 shares of our common stock were repurchased and cancelled at the time of the transaction for a total of $0.4 million. No common stock repurchases were made in the three month ended March 31, 2024. As of March 31, 2024, there was $185.1 million of authorization remaining under Delek's aggregate stock repurchase program.

•diminishment 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;

•the impact on commercial activity and other economic effects of any widespread public health crisis, including uncertainty regarding the timing, pace and extent of economic recovery following any such crisis;

•general economic and business conditions affecting the southern, southwestern and western United States ("U.S")., 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 safety initiative and periodic turnaround projects;

(together with OPEC, “OPEC+”) regarding production and pricing and disputes between OPEC+ members regarding the same;

•disruption, failure, or cybersecurity breaches affecting or targeting our information technology ("IT"), systems and controls, our infrastructure, or the infrastructure of our cloud-based IT service providers;

•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. All forward-looking statements included in this report are based on information available to us on the date of this report. We undertake no obligation to revise or update any forward-looking statements as a result of new information, future events or otherwise.

Management's Discussion and Analysis

Executive Summary: Management's View of Our Business and Strategic Overview

Management's View of Our Business

We are an integrated downstream energy business focused on petroleum refining, the transportation, storage and wholesale distribution of crude oil, intermediate and refined products and convenience store retailing. Our operating segments consist of refining, logistics, and retail, and are discussed in the sections that follow.

Business and Economic Environment Overview

Our focus on safe and reliable operations is a pillar which underlines all of our business activities. We continue to identify opportunities to mitigate market risk and focus on efforts that improve our overall cost structure while not compromising operational excellence. Although overall average crack spreads were lower than the first quarter of 2023, crack spreads increased from the end of 2023. Refining margins remained strong and demand for refined products continues to be robust driven by the continued constrained supply in the markets we serve. We will continue to identify opportunities for operational efficiency improvements. The domestic West Texas Intermediate ("WTI") differentials compared to Brent continued to be favorable, but the WTI Midland to Cushing remained consistent in comparison to the first quarter of 2023. Our logistics segment again contributed strong results driven by increased volumes from the Delaware Basin and rate increases. Logistics also continues to benefit from strong performance amongst our pipeline joint venture investments. Retail stores experienced normal seasonal results and performed well and we are realizing the benefit of store optimization activities as margins have increased, and we expect to begin seeing benefits from successful re-branding.

The near term economic outlook still has some uncertainty with geopolitical instability, and as a result we continue to progress our business transformation focused on enterprise-wide opportunities to improve the efficiency of our cost structure. The expectation of reduction in the reliance of liquid fuels, increased regulatory pressures, and volatility in the commodity markets, are considerations that Delek must balance as we move forward with our strategic initiatives.

The energy-related legislation passed with the Inflation Reduction Act ("IRA") encompasses clean energy financial incentives that are expected to increase capital investment opportunities that focus on the development of production capacity for liquid fuels with lower GHG. Gulf coast industries should be well positioned for growth, particularly if global trade becomes tied to environmental attributes. Following the enactment of the IRA, Delek is also investing in carbon capture technology and continuing our production of biodiesel fuel to meet the world’s growing demand for low-carbon energy. We were selected by the Department of Energy's ("DOE") Office of Clean Energy Demonstrations to negotiate a cost-sharing agreement in support of a carbon capture pilot project at the Big Spring refinery. The DOE Carbon Capture Large-Scale Pilot Project program provides 70% cost-share for up to $95 million of federal funding to support project development. The project will deploy carbon capture technology at the Big Spring refinery's FCC unit, while maintaining existing production capabilities and turnaround schedule. Expectations for the project are to capture 145,000 metric tons of carbon dioxide per year, as well as reduce health-harming pollutants, such as sulfur oxide and particulate matter. Carbon dioxide is expected to be transported by existing pipelines for permanent storage or utilization.

Our focus on reduction of GHG is a key objective as we strive to be a leader in the transition to a carbon neutral future. Delek's Sustainable Operations Team ("SOT") which is led by our Executive Vice President, Operations coordinates execution of our sustainability objectives including ensuring enterprise strategies, business unit operations, capital spending plans, supply chain and personnel pipeline are in alignment and operating as needed to meet established goals. Delek prioritizes stewardship of the environment, and we focus on how to positively impact our shareholders, employees, customers, and the communities where we operate.

We want to reward our shareholders with a disciplined and balanced capital allocation framework. As we strengthen our relative financial position, we believe a balanced approach between shareholder returns and balance sheet improvement is appropriate. In 2024, we returned $15.7 million of capital to shareholders through dividends.

Our near-term focus is centered around the following: (1) operations excellence, (2) financial strength and flexibility and (3) strategic initiatives which includes unlocking the "sum of the parts" value of our existing business while identifying growth opportunities to enhance the Company's scale and diversify revenue streams. In 2024, we took steps to refinance the Delek Logistics long term debt, ending the quarter with a more attractive maturity profile. Delek Logistics also completed a public equity offering of its common units in March 2024. We believe each of these steps is consistent with our focus on strategic initiatives which includes unlocking the "sum of the parts". See further discussion in the "Strategic Objectives" section below.

See further discussion on macroeconomic factors and market trends, including the impact on 2024, in the ‘Market Trends’ section below.

Other 2024 Developments

On March 12, 2024, Delek Logistics completed a public offering of its common units in which it sold 3,584,416 common units (including an overallotment option of 467,532 common units) to the underwriters of the offering at a price to the public of $38.50 per unit. The proceeds received from this offering (net of underwriting discounts, commissions and expenses) were $132.3 million and were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

On March 13, 2024, Delek Logistics sold $650.0 million in aggregate principal amount of 8.625% Senior Notes due 2029 (the “Delek Logistics 2029 Notes”), at par. Net proceeds were used to redeem the Delek Logistics 2025 Notes including accrued interest, pay off the Delek Logistics Term Loan Facility including accrued interest and to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

Management's Discussion and Analysis

On March 29, 2024, Delek Logistics entered into a fourth amendment to the Delek Logistics Revolving Facility which among other things increased the U.S. Revolving Credit Commitments (as defined in the Delek Logistics Credit Facility) by an amount equal to $100.0 million resulting in aggregate lender commitments under the Delek Logistics Revolving Credit Facility in an amount of $1,150.0 million.

On April 17, 2024, Delek Logistics sold $200 million in aggregate principal amount of additional 8.625% senior notes due 2029 (the “Additional 2029 Notes”), at 101.25%. The Additional 2029 Notes were issued under the same indenture as the Delek Logistics 2029 Notes and formed a part of the same series of notes as the Delek Logistics 2029 Notes. The net proceeds were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

These steps improved availability under the Delek Logistics Revolving Facility to approximately $800 million and helped create the foundation for a "sum of the parts" initiative.

Refining Overview

The refining segment (or "Refining") processes crude oil and other feedstocks for the manufacture of transportation motor fuels, including various grades of gasoline, diesel fuel, 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 March 31, 2024. A high-level summary of the refinery activities is presented below:

	Tyler, Texas refinery (the "Tyler refinery")	El Dorado, Arkansas refinery (the "El Dorado refinery")	Big Spring, Texas refinery (the "Big Spring refinery")	Krotz Springs, Louisiana refinery (the "Krotz Springs refinery")
Total Nameplate Capacity (bpd)	75,000	80,000	73,000	74,000
Primary Products	Gasoline, jet fuel, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, petroleum coke and sulfur	Gasoline, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, asphalt and sulfur	Gasoline, jet fuel, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, aromatics and sulfur	Gasoline, jet fuel, high-sulfur diesel, light cycle oil, liquefied petroleum gases, propylene and ammonium thiosulfate
Relevant Crack Spread Benchmark	Gulf Coast 5-3-2	Gulf Coast 5-3-2 (1)	Gulf Coast 3-2-1 (2)	Gulf Coast 2-1-1 (3)
Marketing and Distribution	The refining segment's petroleum-based products are marketed primarily in the south central and southwestern regions of the United States, and the refining segment also ships and sells gasoline into wholesale markets in the southern and eastern United States. Motor fuels are sold under the Alon or Delek brand through various terminals to supply Alon or Delek branded retail sites. In addition, we sell motor fuels through our wholesale distribution network on an unbranded basis.

(1) While there is variability in the crude slate and the product output at the El Dorado refinery, we compare our per barrel refined product margin to the U.S. Gulf Coast ("Gulf Coast") 5-3-2 crack spread because we believe it to be the most closely aligned benchmark.

(2) Our Big Spring refinery is capable of processing substantial volumes of sour crude oil, which has historically cost less than intermediate, and/or substantial volumes of sweet crude oil, and therefore the West Texas Intermediate ("WTI") Cushing/ West Texas Sour ("WTS") price differential, taking into account differences in production yield, is an important measure for helping us make strategic, market-respondent production decisions.

(3) The Krotz Springs refinery has the capability to process substantial volumes of light sweet crude oil to produce a high percentage of refined light products.

Our 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. In addition, the refining segment includes our wholesale crude operations.

Logistics Overview

Our logistics segment (or "Logistics") gathers, transports and stores crude oil and natural gas; markets, distributes, transports and stores refined products; and disposes and recycles water in select regions of the southeastern United States, West Texas and New Mexico for our refining segment and third parties. It is comprised of the consolidated balance sheet and results of operations of Delek Logistics (NYSE: DKL), where we owned a 72.7% interest at March 31, 2024. Delek Logistics was formed by Delek in 2012 to own, operate, acquire and construct crude oil and refined products logistics and marketing assets. A substantial majority of Delek Logistics' assets are currently integral to our refining and marketing operations. The logistics segment's gathering and processing business owns or leases capacity on approximately 398 miles of crude oil transportation pipelines, approximately 406 miles of refined product pipelines, and an approximately 1,400-mile crude oil gathering system of which 489 miles is decommissioned. The storage and transportation business owns or leases associated crude oil storage tanks with an aggregate of approximately 10.0 million barrels of active shell capacity. It also owns and operates nine light product terminals and markets light products using third-party terminals. Logistics has strategic investments in pipeline joint ventures that provide access to pipeline capacity as well as the potential for earnings from joint venture operations. The logistics segment owns or leases approximately 199 tractors and 353 trailers used to haul primarily crude oil and other products for related and third parties.

Retail Overview

Our retail segment (or "Retail") at March 31, 2024 includes the operations of 250 owned and leased convenience store sites located primarily in West Texas and New Mexico. Our convenience stores typically offer various grades of gasoline and diesel under the DK or Alon brand name and food products, food service, tobacco products, non-alcoholic and alcoholic beverages, general merchandise as well as money orders to the

27 |

Management's Discussion and Analysis

public, primarily under the DK or Alon brand names. Substantially all of the motor fuel sold through our retail segment is supplied by our Big Spring refinery, which is transferred to the retail segment at prices substantially determined by reference to published commodity pricing information.

Corporate and Other Overview

Our corporate activities, results of certain immaterial operating segments, and intercompany eliminations are reported in 'corporate, other and eliminations' in our segment disclosures. Additionally, our corporate activities include certain of our commodity and other hedging activities.

Strategic Objectives

It is vitally important that our strategic objectives, especially in view of the evolutionary direction of our macroeconomic and geopolitical environment, involves a process of continuous evaluation of our business model in terms of cost structure, as well as long-term economic and operational sustainability. More consolidation in our industry is expected from increased cost pressures due in part to the regulatory environment continuing to move towards reducing carbon emissions and transitioning to renewable energy in the long-term. However, we believe we are uniquely positioned as a leader in operating and excelling in niche markets and could continue capitalizing on and growing our integrated business model. To compete under historic environmental and regulatory changes, companies in our industry will need to be adaptive, forward-thinking and strategic in their approach to long-term sustainability.

The emphasis on environmental responsibility and long-term economic and environmental sustainability has increased. Demand for additional transparency continues to evolve. As we evaluate our current sustainability and Environmental, Social and Governance ("ESG") positioning in the market, we also must integrate a broader sustainability view into all of our activities, both operational and strategic. We have developed overarching key objectives that guide us when we formulate our strategic plans.

Key Objectives

Certain fundamental principles are foundational to our long-term strategy and direct us as we develop our strategic objectives. With that in mind, we have identified the following overarching key objectives:

I.    Operational Excellence

II.    Financial Strength and Flexibility

III.    Strategic Initiatives

Operational Excellence

We are committed to operational excellence which includes maintaining safe, reliable, and environmentally responsible operations. It also encompasses the dedication and drive for constant improvement across our operations in reliability, safety, and efficiency. Delek prioritizes stewardship of the environment, and we focus on how to positively impact our shareholders, employees, customers, and the communities where we operate. We understand that if our assets run reliably and safely, it is better for the safety of our employees, communities, and environment. We believe that focusing on people, processes and equipment will lead to improved utilization and yields and ultimately better employee retention and lower costs, which translates to improved returns for our shareholders. For 2024, we will be focused on the following:

•Prioritize safety and environmental compliance by implementing foundational best practices to increase operations ability to provide safe, compliant, and reliable operations.

•Focus on operational excellence by building out our operations centric area business teams, frontline supervisor training as well as other key competency training.

•Execute a major turnaround at the Krotz Springs refinery, focusing on outage spend and optimizing downtime and implementing margin enhancement .

•Identify and evaluate organic growth projects that improve yield and increase utilization.

•Continue our progression of digital system implementations that will improve our ability to understand all aspects of our business as well as our ability to make real-time and forward-looking operational decisions. Automate processes and shift operational roles to higher value-added activities.

Financial Strength and Flexibility

In our industry, as with many volatile businesses, it is very important to make capital investments with accretive returns and maintain a debt balance at a comfortable leverage ratio. We want to reward our shareholders and investors with a disciplined and balanced capital allocation framework, which we believe will strengthen shareholder value by, among other things, a stable dividend complemented by opportunistic share repurchases. We are also committed to lowering costs and improving the efficiency of our cost structure in all aspects of our business. For 2024, we will be focused on the following:

•Reward our shareholders and investors with a disciplined and balanced capital allocation framework, including opportunities to strengthen our balance sheet by reducing debt or opportunistically repurchasing shares with excess cash.

•Pursue strategic investments and acquisitions with a focus on geographic and revenue stream diversity.

28 |

Management's Discussion and Analysis

•Build upon the zero-based budget foundation set in 2022 by implementing phase 2, which includes further improvements to our operating and general and administrative cost structure.

Strategic Initiatives

One of our near-term strategic initiatives is centered around unlocking the "sum of the parts" value of our existing business while identifying growth opportunities to diversify the Company’s geographic footprint and revenue stream, including in the alternative energy markets, as well as enhance its scale, compensate investors and develop other areas of its business. For 2024, we will be focused on the following:

•Execute on our strategic initiatives, which may include opportunities to monetize our retail operations or some of our investment in Delek Logistics. The goal being, to help unlock value embedded in the Delek valuation, while also improving liquidity in the market for Delek Logistics units without diluting overall Delek Logistics market capitalization.

•Identify and evaluate investment opportunities that fit our sustainability view and integrate into our current asset footprint, including strategic investments or joint ventures in renewables, incubator investments in new technologies, and other core-business investments that could improve our scalability and agility.

•Deploy integrated solutions to simplify architecture, data management and cybersecurity.

2024 Strategic Developments

The following table highlights our 2024 Strategic Developments:

	2024 Key Initiatives
2024 Strategic Developments	Operational Excellence	Financial Strength & Flexibility	Strategic Initiatives
Investing in Energy Transition: We were selected by the DOE Office of Clean Energy Demonstrations to negotiate a cost-sharing agreement in support of a carbon capture pilot project at the Big Spring refinery. The DOE Carbon Capture Large-Scale Pilot Project program provides 70% cost-share for up to $95 million of federal funding to support project development.			ü
Extending Long Term Debt Maturities: On March 13, 2024, Delek Logistics sold $650.0 million in aggregate principal amount of 8.625% Senior Notes due 2029, at par. Net proceeds were used to redeem the Delek Logistics 2025 Notes including accrued interest, pay off the Delek Logistics Term Loan Facility including accrued interest and to repay borrowings under the Delek Logistics Revolving Facility. On April 17, 2024, Delek Logistics sold $200 million in aggregate principal amount of additional 8.625% senior notes due 2029 (the “Additional 2029 Notes”), at 101.25%. The Additional 2029 Notes were issued under the same indenture as the Delek Logistics 2029 Notes and formed a part of the same series of notes as the Delek Logistics 2029 Notes. The net proceeds were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.		ü
Strengthening the Balance Sheet: On March 12, 2024, Delek Logistics completed a public offering of its common units in which it sold 3,584,416 common units (including an overallotment option of 467,532 common units) to the underwriters of the offering at a price to the public of $38.50 per unit. The proceeds received from this offering (net of underwriting discounts, commissions and expenses) were $132.3 million and were used to repay borrowings under the Delek Logistics Revolving Facility.		ü

Market Trends

Our results of operations are significantly affected by fluctuations in the prices of certain commodities, including, but not limited to, crude oil, gasoline, distillate fuel, biofuels, natural gas and electricity, among others. Historically, the impact of commodity price volatility on our refining margins (as defined in our "Non-GAAP Measures" in MD&A Item 2), specifically as it relates to the price of crude oil as compared to the price of refined products and timing differences in the movements of those prices (subject to our inventory costing methodology), as well as location differentials, may be favorable or unfavorable compared to peers. Additionally, our refining margin profitability is impacted by regulatory factors, including the cost of renewable identification numbers ("RINs").

We have positioned the Company to continue to run safely, reliably and environmentally responsibly at near or above nameplate capacity while leveraging our Delek Logistics and retail lines of business with an eye towards the One Delek vision. Increased geopolitical risks and general elevated tensions in the Middle East have put upward pressure on crude oil prices. Many uncertainties remain with respect to the global supply and demand of the crude oil and refined products markets and it is difficult to predict the ultimate economic impacts this may have on our operations. We expect gasoline and diesel demand to continue to follow typical seasonal patterns as we continue into the spring and summer driving season.

29 |

Management's Discussion and Analysis

See below for further discussion on how certain key market trends impact our operating results.

Crude Prices

WTI crude oil represents the largest component of our crude slate at all of our refineries, and can be sourced through our gathering channels or optimization efforts from Midland, Texas or Cushing, Oklahoma or other locations. We manage our supply chain risk to ensure that we have the barrels to meet our crude slate consumption plan for each month through gathering supply contracts and throughput agreements on various strategic pipelines, some of which include those where we hold equity method investments. We manage market price risk on crude oil through financial derivative hedges, in accordance with our risk management strategies.

The table below reflects the quarterly average prices of WTI Midland and WTI Cushing crude oil for each of the quarterly periods in 2023 and for the first quarterly period in 2024.

Crude Pricing Differentials

Historically, domestic refiners have benefited from the discount for WTI Cushing compared to Brent, a global benchmark crude. This generally leads to higher margins in our refineries, as refined product prices are influenced by Brent crude prices and the majority of our crude supply is WTI-linked. Because of our positioning in the Permian basin, including our access to significant sources of WTI Midland crude through our gathering system, we are even further benefited by discounts for WTI Midland/WTI Cushing differentials. When these discounts shrink or become premiums, our reliance on WTI-linked crude pricing, and specifically WTI Midland crude, can negatively impact our refining margins. Conversely, as these price discounts widen, so does our competitive advantage, created specifically by our access to WTI Midland crude sourced through our gathering systems.

The chart below illustrates the key differentials impacting our refining operations, including WTI Cushing to Brent, WTI Midland to WTI Cushing, and Louisiana Light Sweet crude oil ("LLS") to WTI Cushing for each of the quarterly periods in 2023 and for the first quarterly period in 2024.

Management's Discussion and Analysis

Refined Product Prices

We are impacted by refined product prices in two ways: (1) in terms of the prices we are able to sell our refined product for in our refining segment, and (2) in terms of the cost to acquire the refined products to meet Refining production shortfalls (e.g., when we have outages), or to acquire refined fuel products we sell to our wholesale customers in our logistics segment and at our convenience stores in our retail segment. These prices largely depend on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions, domestic and foreign political affairs, production levels, the availability of imports, the marketing of competitive fuels and government regulation.

Our refineries produce the following products:

	Tyler Refinery	El Dorado Refinery	Big Spring Refinery	Krotz Springs Refinery
Primary Products	Gasoline, jet fuel, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, petroleum coke and sulfur	Gasoline, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, asphalt and sulfur	Gasoline, jet fuel, ultra-low-sulfur diesel, liquefied petroleum gases, propylene, aromatics and sulfur	Gasoline, jet fuel, high-sulfur diesel, light cycle oil, liquefied petroleum gases, propylene and ammonium thiosulfate

The charts below illustrate the quarterly average prices of Gulf Coast Gasoline ("CBOB"), U.S. High Sulfur Diesel ("HSD") and U.S. Ultra Low Sulfur Diesel ("ULSD") for each of the quarterly periods in 2023 and for the first quarterly period in 2024.

31 |

Management's Discussion and Analysis

Crack Spreads

Crack spreads are used as benchmarks for predicting and evaluating a refinery's product margins by measuring the difference between the market price of feedstocks/crude oil and the resultant refined products. Generally, a crack spread represents the approximate refining margin resulting from processing one barrel of crude oil into its outputs, generally gasoline and diesel fuel.

The table below reflects the quarterly average Gulf Coast 5-3-2 ULSD, 3-2-1 ULSD and 2-1-1 HSD/LLS crack spreads for each of the quarterly periods in 2023 and for the one quarterly period in 2024.

RIN Volatility

Environmental regulations and the political environment continue to affect our refining margins in the form of volatility in the price of RINs. We enter into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs of our credits for commitments required by the U.S. Environmental Protection Agency (“EPA”) to blend biofuels into fuel products ("RINs Obligation"). On a consolidated basis, we work to balance our RINs Obligation in order to minimize the effect of RINs prices on our results. While we obtain RINs in our refining and logistics segments through our ethanol and biodiesel blending and generate RINs through biodiesel production, our refining segment still must purchase additional RINs to satisfy its obligations. Additionally, our ability to obtain RINs through blending is limited by our refined product slate, blending capabilities and market constraints. The cost to purchase these additional RINs is a significant cash outflow for our business. Increases in the market prices of RINs generally adversely affect our results of operations through changes in fair value to our existing RINs Obligation, to the extent we do not have offsetting RINs inventory on hand or effective economic hedges through net forward purchase commitments. RINs prices are highly sensitive to regulatory and political influence and conditions, and therefore often do not correlate to movements in crude oil prices, refined product prices or crack spreads. Because of the volatility in RINs prices, it is not possible to predict future RINs cost with certainty, and movements in RINs prices can have significant and unanticipated adverse effects on our refining margins that are outside of our control.

The chart below illustrates the volatility in RINs for each of the quarterly periods in 2023 and for the one quarterly period in 2024.

Management's Discussion and Analysis

Energy Costs

Energy costs are a significant element of our Refining Earnings before interest, taxes, depreciation and amortization ("EBITDA") and can significantly impact our ability to capture crack spreads, with natural gas representing the largest component. Natural gas prices are driven by supply-side factors such as amount of natural gas production, level of natural gas in storage and import and export activity, while demand-side factors include variability of weather, economic growth and the availability and price of other fuels. Refiners and other large-volume fuel consumers may be more or less susceptible to volatility in natural gas prices depending on their consumption levels as well as their capabilities to switch to more economical sources of fuel/energy. Additionally, geographic location of facilities make consumers vulnerable to price differentials of natural gas available at different supply hubs. Within Delek’s geographic footprint, we source the majority of our natural gas from the Gulf Coast, and secondarily from the Permian, coinciding with the physical locations of our refineries. We manage our risk around natural gas prices by entering into variable and fixed-price supply contracts in both the Gulf and Permian Basin or by entering into derivative hedges based on forecasted consumption and forward curve prices, as appropriate, in accordance with our risk policy.

The chart below illustrates the quarterly average prices of Waha (Permian Basin) and Henry Hub (Gulf Coast) per million British Thermal Units ("MMBtu") beginning with the first quarter of 2023 through the first quarter of 2024.

Non-GAAP Measures

Our management uses certain non-Generally Accepted Accounting Principles (“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:

•EBITDA - calculated as net income (loss) attributable to Delek adjusted to add back interest expense, income tax expense, depreciation and amortization; and

•Refining margin - calculated as gross margin (which we define as sales minus cost of sales) adjusted for operating expenses and depreciation and amortization included in cost of sales.

We believe these non-GAAP operational and financial measures are useful to investors, lenders, ratings agencies and analysts to assess our ongoing performance because, when reconciled to their most comparable GAAP financial measure, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and they may obscure our underlying results and trends.

Non-GAAP measures have important limitations as analytical tools, because they exclude some, but not all, items that affect net earnings and operating income. These measures should not be considered substitutes for their most directly comparable U.S. GAAP financial measures.

Non-GAAP Reconciliations

Management's Discussion and Analysis

Net Revenues

We generated net revenues of $3,227.6 million and $3,924.3 million during the three months ended March 31, 2024 and 2023, respectively, a decrease of $696.7 million, or 17.8%. The decrease in net revenues was primarily due to the following:

•in our refining segment, decreases in the average price of U.S. Gulf Coast gasoline of 7.1% and ULSD of 8.7%,and decreases in wholesale activity, partially offset by an increase in sales volume and an increase in the average price of U.S. Gulf Coast HSD of 1.6%;

•in our logistics segment, an increase in terminalling and marketing fees due to rate increases as well as higher volumes associated with Tyler Refinery operations which were negatively impacted in prior year as a result of turnaround activities, partially offset by decreases in our West Texas marketing operations; and

•in our retail segment, a decrease in total fuel sales primarily attributable to a $0.19 decrease in average price charged per gallon sold and a decrease in merchandise sales primarily driven by the same-store sales decrease of 4.1%.

Cost of materials and other was $2,797.3 million for the three months ended March 31, 2024, compared to $3,439.6 million for three months ended March 31, 2023, a decrease of $642.3 million, or 18.7%. The net decrease in cost of materials and other primarily related to the following:

•decreased wholesale activity and decreased RINs pricing, partially offset by an increase in the cost of crude oil feedstocks at the refineries, including a 1.4% increase in the average cost of WTI Cushing crude oil and a 1.4% increase in the average cost of WTI Midland crude oil and an increase in sales volume;

•decrease in logistics costs due to lower natural gas costs partially offset by an increases in the average volumes of gasoline and diesel sold; and

•a decrease in retail cost of materials and other due to 7.0% decrease in average cost per gallon sold.

Operating Expenses

Operating expenses (included in both cost of sales and other operating expenses) were $239.6 million for the three months ended March 31, 2024 compared to $197.8 million in three months ended March 31, 2023, an increase of $41.8 million, or 21.1%. The increase in operating expenses was primarily driven by the following:

•an increase in maintenance costs; and

•an increase in employee costs.

These increases were partially offset by the following:

•lower natural gas prices.

General and Administrative Expenses

General and administrative expenses were $64.4 million for the three months ended March 31, 2024 compared to $71.5 million in three months ended March 31, 2023, a decrease of $7.1 million, or 9.9%. The decrease was primarily driven by a decrease in employee costs including incentive compensation costs.

Depreciation and Amortization

Depreciation and amortization (included in both cost of sales and other operating expenses) was $95.2 million and $83.4 million for the three months ended March 31, 2024 and 2023, respectively, an increase of $11.8 million, or 14.1%. The increase was a result of a general increase in our fixed asset base due to capital projects and turnarounds completed.

Other Operating Income, Net

Other operating income, net was $1.6 million and $10.8 million for the three months ended March 31, 2024 and 2023, respectively, a decrease of $9.2 million, primarily due to decreased hedge gains associated with our derivatives.

Management's Discussion and Analysis

Non-Operating Expenses, Net

Interest Expense, Net

Interest expense, net was $87.7 million in the three months ended March 31, 2024, compared to $76.5 million for three months ended March 31, 2023, an increase of $11.2 million, or 14.6% primarily due to the following:

•an increase in the average effective interest rate of 257 basis points during the three months ended March 31, 2024 compared to the three months ended March 31, 2023 (where effective interest rate is calculated as interest expense divided by the net average borrowings/obligations outstanding);

•a decrease in net average borrowings outstanding (including the obligations under the supply and offtake agreements which have an associated interest charge) of approximately $454.8 million during the three months ended March 31, 2024 (calculated as a simple average of beginning borrowings/obligations and ending borrowings/obligations for the period) compared to the three months ended March 31, 2023; and

•debt extinguishment costs of $3.6 million in the three months ended March 31, 2024 related to the payoff of the Delek Logistics Term Loan Facility and Delek Logistics 2025 Notes with proceeds from the Delek Logistics 2029 Notes issued in March 2024.

Results from Equity Method Investments

We recognized income from equity method investments of $21.9 million for the three months ended March 31, 2024, compared to $14.6 million for the three months ended March 31, 2023, an increase of $7.3 million. This increase was primarily driven by the following:

•an increase in income from our investment in W2W Holdings LLC to $9.4 million during the three months ended March 31, 2024 from $4.5 million in the three months ended March 31, 2023.

Income Taxes

For the three months ended March 31, 2024, we recorded an income tax benefit of $7.2 million compared to expense of $15.8 million for the three months ended March 31, 2023, primarily driven by the following:

•a decrease in pre-tax net income of $120.4 million, and

•Our effective tax rates were 22.2% and 18.0% for the three months ended March 31, 2024 and 2023, respectively, due to the impact of fixed dollar favorable permanent differences on the tax rate and changes in valuation allowance on state attributes when calculating a year-to-date effective tax rate to approximate the estimated annual effective tax rate.

Refining Segment

The tables and charts below set forth selected information concerning our refining segment operations ($ in millions, except per barrel amounts):

Selected Refining Financial Information
	Three Months Ended March 31,
	2024		2023
Revenues	$	3,108.3	$	3,794.5
Cost of materials and other	2,839.9		3,458.8

Operating expenses (excluding depreciation and amortization)	$	165.8	$	139.1

Factors Impacting Refining Profitability

Our profitability in the refining segment is substantially determined by the difference between the cost of the crude oil feedstocks we purchase and the price of the refined products we sell, referred to as the "crack spread", "refining margin" or "refined product margin". Refining margin is used as a metric to assess a refinery's product margins against market crack spread trends, where "crack spread" is a measure of the difference between market prices for crude oil and refined products and is a commonly used proxy within the industry to estimate or identify trends in refining margins.

The cost to acquire feedstocks and the price of the refined petroleum products we ultimately sell from our refineries depend on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions such as hurricanes or tornadoes, local, domestic and foreign political affairs, global conflict, production levels, the availability of imports, the marketing of competitive fuels and government regulation. Other significant factors that influence our results in the refining segment include operating costs (particularly the cost of natural gas used for fuel and the cost of electricity), seasonal factors, refinery utilization rates and planned or unplanned maintenance activities or turnarounds. Moreover, while the fluctuations in the cost of crude oil are typically reflected in the prices of light refined products, such as gasoline and diesel fuel, the price of other residual products, such as asphalt, coke, carbon black oil and liquefied petroleum gas ("LPG") are less likely to move in parallel with crude cost. This could cause additional pressure on our realized margin during periods of rising or falling crude oil prices.

Additionally, our margins are impacted by the pricing differentials of the various types and sources of crude oil we use at our refineries and their relation to product pricing. Our crude slate is predominantly comprised of WTI crude oil. Therefore, favorable differentials of WTI compared to other crude will favorably impact our operating results, and vice versa. Additionally, because of our gathering system presence in the Midland area and the significant source of crude specifically from that region into our network, a widening of the WTI Cushing less WTI Midland spread will favorably influence the operating margin for our refineries. Alternatively, a narrowing of this differential will have an adverse effect on our operating margins. Global product prices are influenced by the price of Brent which is a global benchmark crude. Global product prices influence product prices in the U.S. As a result, our refineries are influenced by the spread between Brent and WTI Midland. The Brent less WTI Midland spread represents the differential between the average per barrel price of Brent crude oil and the average per barrel price of WTI Midland crude oil. A widening of the spread between Brent and WTI Midland will favorably influence our refineries' operating margins. Also, the Krotz Springs refinery is influenced by the spread between Brent and LLS. The Brent less LLS spread represents the differential between the average per barrel price of Brent and the average per barrel price of LLS crude oil. A discount in LLS relative to Brent will favorably influence the Krotz Springs refinery operating margin.

Finally, Refining EBITDA is impacted by regulatory costs associated with the cost of RINs as well as energy costs, including the cost of natural gas. In periods of unfavorable regulatory sentiment, RINs prices can increase at higher rates than crack spreads, or even when crack spreads are declining. This can be particularly impactful on smaller refineries, where the operating cost structure does not have as much scalability as larger refineries. Additionally, volatility in energy costs, which are captured in our operating expenses and impact our Refining EBITDA, can significantly impact our ability to capture crack spreads, with natural gas representing the most significant component. Within Delek’s geographic footprint, we source the majority of our natural gas from the Gulf Coast, and secondarily from the Permian, and we do not currently have the capability at our refineries to switch our energy consumption to utilize alternative sources of fuel. For this reason, unfavorable Gulf Coast (Henry Hub) differentials can impact our crack spread capture.

Management's Discussion and Analysis

The cost to acquire the refined fuel products we sell to our wholesale customers in our logistics segment and at our convenience stores in our retail segment largely depends on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions, domestic and foreign political affairs, production levels, the availability of imports, the marketing of competitive fuels and government regulation.

In addition to the above, it continues to be a strategic and operational objective to manage price and supply risk related to crude oil that is used in refinery production, and to develop strategic sourcing relationships. For that purpose, from a pricing perspective, we enter into commodity derivative contracts to manage our price exposure to our inventory positions, future purchases of crude oil and ethanol, future sales of refined products or to fix margins on future production. We also enter into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage our RINs Obligation. Additionally, from a sourcing perspective, we often enter into purchase and sale contracts with vendors and customers or take physical or financial commodity positions for crude oil that may not be used immediately in production, but that may be used to manage the overall supply and availability of crude expected to ultimately be needed for production and/or to meet minimum requirements under strategic pipeline arrangements, and also to optimize and hedge availability risks associated with crude that we ultimately expect to use in production. Such transactions are inherently based on certain assumptions and judgments made about the current and possible future availability of crude. Therefore, when we take physical or financial positions for optimization purposes, our intent is generally to take offsetting positions in quantities and at prices that will advance these objectives while minimizing our positional and financial statement risk. However, because of the volatility of the market in terms of pricing and availability, it is possible that we may have material positions with timing differences or, more rarely, that we are unable to cover a position with an offsetting position as intended. Such differences could have a material impact on the classification of resulting gains/losses, assets or liabilities, and could also significantly impact Refining EBITDA.

For our Big Spring refinery, we compare our per barrel refining margin to the Gulf Coast 3-2-1 crack spread consisting of (Argus pricing) WTI Cushing crude, U.S. Gulf Coast CBOB gasoline and Gulf Coast ultra-low sulfur diesel. For 2023, for our Krotz Springs refinery, we compare our per barrel refining margin to the Gulf Coast 2-1-1 crack spread consisting of (Argus pricing) LLS crude oil, (Argus pricing) U.S. Gulf Coast CBOB gasoline and 50% of (Argus pricing) U.S. Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel) and 50% of (Platts pricing) U.S. Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel). For 2024, for our Krotz Springs refinery, we compare our per barrel refining margin to the Gulf Coast 2-1-1 crack spread consisting of (Argus pricing) LLS crude oil, (Argus pricing) U.S. Gulf Coast CBOB gasoline and (Platts pricing) U.S. Gulf Coast Pipeline No. 2 heating oil (high sulfur diesel). The Tyler refinery's crude oil input is primarily WTI Midland and East Texas, while the El Dorado refinery's crude input is primarily a combination of WTI Midland, local Arkansas and other domestic inland crude oil. The Big Spring refinery’s crude oil input is primarily comprised of WTS and WTI Midland. The Krotz Springs refinery’s crude oil input is primarily comprised of LLS and WTI Midland.

Management's Discussion and Analysis

Refining Segment Operational Comparison of the Three Months Ended March 31, 2024 versus the Three Months Ended March 31, 2023

Revenues

Revenues for the refining segment decreased $686.2 million, or 18.1%, in the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The decrease was primarily driven by the following:

•a decrease in the average price of U.S. Gulf Coast gasoline of 7.1% and ULSD of 8.7%; and

•a decrease in wholesale activity.

These decreases were partially offset by the following:

•an increase in sales volumes primarily associated with Tyler Refinery operations which were negatively impacted in prior year as a result of turnaround activities; and

•an increase in the average price of U.S. Gulf Coast HSD of 1.6%.

Revenues included sales to our retail segment of $93.9 million and $102.6 million and sales to our logistics segment of $92.9 million and $91.1 million for the three months ended March 31, 2024 and 2023, respectively. We eliminate this intercompany revenue in consolidation.

Cost of Materials and Other

Cost of materials and other decreased $618.9 million, or 17.9%, in the three months ended March 31, 2024 compared to the three months ended March 31, 2023. This decrease was primarily driven by the following:

•a decrease in wholesale activity; and

•a decrease in RINs pricing.

These decreases were partially offset by the following:

•increases in the cost of WTI Cushing crude oil, from an average of $75.96 per barrel to an average of $77.01, or 1.4%, and increases in the cost of WTI Midland crude oil, from an average of $77.50 per barrel to an average of $78.55, or 1.4%.

•an increase in sales volumes primarily associated with Tyler Refinery operations which were negatively impacted in prior year as a result of turnaround activities.

Our refining segment purchases finished product from our logistics segment and has multiple service agreements with our logistics segment which, among other things, require the refining segment to pay terminalling and storage fees based on the throughput volume of crude and finished product in the logistics segment pipelines and the volume of crude and finished product stored in the logistics segment storage tanks, subject to minimum volume commitments. These costs and fees were $139.2 million and $124.6 million during the three months ended March 31, 2024 and 2023, respectively. We eliminate these intercompany fees in consolidation.

Refining Margin

Refining margin decreased by $67.3 million, or 20.0%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, with a refining margin percentage of 8.6% as compared to 8.8% for the three months ended March 31, 2024 and 2023, respectively, primarily driven by the following:

•a 29.1% decrease in the 5-3-2 crack spread (the primary measure for the Tyler refinery and El Dorado refinery) and a 29.6% decrease in the average Gulf Coast 3-2-1 crack spread (the primary measure for the Big Spring refinery).

These decreases were partially offset by the following:

•a 1.7% increase in the average Gulf Coast 2-1-1 crack spread (the primary measure for the Krotz Springs refinery);

•an increase in sales volumes primarily associated with Tyler Refinery operations which were negatively impacted in prior year as a result of turnaround activities; and

•lower natural gas prices.

Management's Discussion and Analysis

Operating Expenses

Operating expenses increased by $26.7 million, or 19.2%, in the three months ended March 31, 2024, compared to three months ended March 31, 2023. The increase in operating expenses was primarily driven by the following:

•higher employee, outside service and maintenance costs.

These increases were partially offset by the following:

•lower natural gas prices in 2024.

EBITDA

EBITDA decreased by $91.0 million, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily due to a decrease in refining margin driven by decreased crack spreads, partially offset by an increase in sales volumes primarily associated with Tyler Refinery operations which were negatively impacted in prior year as a result of turnaround activities.

(3)     Consists of terminalling throughputs at our Tyler, Big Spring, Big Sandy and Mount Pleasant, Texas terminals, El Dorado and North Little Rock, Arkansas terminals and Memphis and Nashville, Tennessee terminals.

Logistics revenue is largely based on fixed-fee or tariff rates charged for throughput volumes running through our logistics network, where many of those volumes are contractually protected by minimum volume commitments ("MVCs"). To the extent that our logistics volumes are not subject to MVCs, our Logistics revenue may be negatively impacted in periods where our customers are experiencing economic pressures or reductions in demand for their products. Additionally, certain of our throughput arrangements contain deficiency credit provisions that may require us to defer excess MVC fees collected over actual throughputs to apply toward MVC deficiencies in future periods. With respect to our equity method investments in pipeline joint ventures, our earnings from those investments (which is based on our pro rata ownership percentage of the joint venture's recognized net income or loss) are directly impacted by the operations of those joint ventures. Items impacting the joint venture net income (loss) may include (but are not limited to) the following: long-term throughput contractual arrangements and related MVCs and, in some cases, deficiency credit provisions; the demand for walk-up nominations; applicable rates or tariffs; long-lived asset or other impairments assessed at the joint venture level; and pipeline releases or other contingent liabilities. With respect to our West Texas marketing activities, our profitability is dependent upon the cost of landed product versus the rack price of refined product sold. Our logistics segment is generally protected from commodity price risk because inventory is purchased and then immediately sold at the rack.

(1)Retail fuel margin represents gross margin on fuel sales in the retail segment, and is calculated as retail fuel sales revenue less retail fuel cost of sales. The retail fuel margin per gallon calculation is derived by dividing retail fuel margin by the total retail fuel gallons sold for the period.

(2)Same-store comparisons include year-over-year changes in specified metrics for stores that were in service at both the beginning of the year and the end of the most recent year used in the comparison.

Our retail merchandise sales are driven by convenience, customer service, competitive pricing and branding. Motor fuel margin is sales less the delivered cost of fuel and motor fuel taxes, measured on a cents per gallon basis. Our motor fuel margins are impacted by local supply, demand, weather, competitor pricing and product brand.

Management's Discussion and Analysis

Retail Segment Operational Comparison of the Three Months Ended March 31, 2024 versus the Three Months Ended March 31, 2023

Revenues

Revenues for the retail segment decreased by $11.5 million, or 5.6%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily driven by the following:

•a decrease in total fuel sales which were $122.8 million for the three months ended March 31, 2024 compared to $131.1 million for the three months ended March 31, 2023, primarily attributable to a $0.19 decrease in average price charged per gallon sold; and

•a decrease in merchandise sales to $70.7 million for the three months ended March 31, 2024 compared to $73.9 million for the three months ended March 31, 2023, primarily driven by the same-store sales decrease of 4.1% mostly attributable to tobacco sales.

Cost of Materials and Other

Cost of materials and other for the retail segment decreased by $11.7 million, or 6.9%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily driven by the following:

•a decrease in average cost per gallon of $0.21, or 7.0%.

Our retail segment purchased finished product from our refining segment of $93.9 million and $102.6 million for the three months ended March 31, 2024 and 2023, respectively. We eliminate this intercompany cost in consolidation.

Management's Discussion and Analysis

Liquidity and Capital Resources

Sources of Capital

Our primary sources of liquidity and capital resources are

•cash generated from our operating activities;

•borrowings under our debt facilities; and

•potential issuances of additional equity and debt securities.

At March 31, 2024 our total liquidity amounted to $2.2 billion comprised primarily of $1,424.3 million in unused credit commitments under our revolving credit facilities (as discussed in Note 8 of our condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q) and $753.4 million in cash and cash equivalents. Historically, we have generated adequate cash from operations to fund ongoing working capital requirements, pay quarterly cash dividends and fund operational capital expenditures. On May 2, 2024, our Board of Directors approved a quarterly cash dividend of $0.250 per share of our common stock.

Other funding sources including borrowings under existing credit agreements, and issuance of equity and debt securities have been utilized to meet our funding requirements and support our growth capital projects and acquisitions. In addition, we have historically been able to source funding at terms that reflect market conditions, our financial position and our credit ratings and expect future funding sources to be at terms that are sustainable and profitable for the Company. However, there can be no assurances regarding the availability of future debt or equity financings or whether such financings can be made available on terms that are acceptable to us; any execution of such financing activities will be dependent on the contemporaneous availability of functioning debt or equity markets. Additionally, new debt financing activities will be subject to the satisfaction of any debt incurrence limitation covenants in our existing financing agreements. Our debt limitation covenants in our existing financing documents are usual and customary for credit agreements of our type and reflective of market conditions at the time of their execution. Additionally, our ability to satisfy working capital requirements, to service our debt obligations, to fund planned capital expenditures, or to pay dividends will depend upon future operating performance, which will be affected by prevailing economic conditions in the oil industry and other financial and business factors, including oil prices, some of which are beyond our control.

As of March 31, 2024, we believe we were in compliance with all of our debt maintenance covenants, where the most significant long-term obligation subject to such covenants was the Delek Term Loan Credit Facility (see further discussion in Note 8 of our condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q). Additionally, we were in compliance with covenants during the quarter ended March 31, 2024. Failure to meet the incurrence covenants could impose certain incremental restrictions on our ability to incur new debt and also may limit whether and the extent to which we may pay dividends, as well as impose additional restrictions on our ability to repurchase our stock, make new investments and incur new liens (among others). Such restrictions would generally remain in place until such quarter that we return to compliance under the applicable incurrence based covenants. In the event that we are subject to these incremental restrictions, we believe that we have sufficient current and alternative sources of liquidity, including (but not limited to): available borrowings under our existing Delek Revolving Credit Facility, and for Delek Logistics, under its Delek Logistics Revolving Facility; the allowance to incur an additional $400.0 million of secured debt under the Delek Term Loan Credit Facility (see further discussion of these facilities in Note 8 of our condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q); as well as the possibility of obtaining other secured and unsecured debt, raising capital through equity issuance, or taking advantage of transactional financing opportunities such as sale-leasebacks or joint ventures, as otherwise contemplated and allowed under our incurrence covenants.

Cash Position and Indebtedness

As of March 31, 2024, our total cash and cash equivalents were $753.4 million and we had total long-term indebtedness of approximately $2,496.9 million. The total long-term indebtedness is net of deferred financing costs and debt discount of $61.4 million. Additionally, we had letters of credit issued of approximately $280.5 million. Total unused credit commitments or borrowing base availability, as applicable, under our revolving credit facilities was approximately $1,424.3 million. The decrease of $99.0 million in total long-term principle indebtedness as of March 31, 2024 compared to December 31, 2023 resulted primarily from a decrease in net borrowings under the Delek Revolving Credit Facility and the United Community Bank Revolver, partially offset by an increase in net borrowings under the Delek Logistics Revolving Facility. As of March 31, 2024, our total long-term indebtedness (as defined in Note 8 of the condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q) consisted of the following:

•the Delek Revolving Credit Facility with no outstanding borrowings (maturity of October 26, 2027);

•aggregate principal of $938.1 million under the Delek Term Loan Credit Facility (maturity of November 19, 2029 and effective interest of 10.15%);

•aggregate principal of $565.2 million under the Delek Logistics Revolving Facility (maturity of October 13, 2027 and average borrowing rate of 8.18%);

•aggregate principal of $400.0 million under the Delek Logistics 2028 Notes (due in 2028, with effective interest rate of 7.39%);

•aggregate principal of $650.0 million under the Delek Logistics 2029 Notes (due in 2029, with effective interest rate of 8.81%); and

•aggregate principal of $5.0 million under the United Community Bank Revolver (maturity of June 30, 2024 and average borrowing rate of 7.75%).

50 |

Management's Discussion and Analysis

On March 13, 2024, Delek Logistics sold $650.0 million in aggregate principal amount of 8.625% Senior Notes due 2029, at par. Net proceeds were used to redeem the Delek Logistics 2025 Notes including accrued interest, pay off the Delek Logistics Term Loan Facility including accrued interest and to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

On April 17, 2024, Delek Logistics sold $200 million in aggregate principal amount of additional 8.625% senior notes due 2029 (the “Additional 2029 Notes”), at 101.25%. The Additional 2029 Notes were issued under the same indenture as the Delek Logistics 2029 Notes and formed a part of the same series of notes as the Delek Logistics 2029 Notes. The net proceeds were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

See Note 8 to our accompanying condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q for additional information about our separate debt and credit facilities.

Additionally, we utilize other financing arrangements to finance operating assets and/or, from time to time, to monetize other assets that may not be needed in the near term, when internal cost of capital and other criteria are met. Such arrangements include our inventory intermediation arrangement, which finances a significant portion of our first-in, first-out inventory at the refineries and, from time to time, RINs or other non-inventory product financing liabilities and funded letters of credit. Our inventory intermediation obligation with Citigroup Energy Inc. ("Citi") was $492.7 million at March 31, 2024. See Note 7 of the accompanying condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q for additional information about our inventory intermediation agreement. Our product financing liabilities consisted primarily of RIN financings as of March 31, 2024, and totaled $31.0 million, all of which is due in the next 12 months. See further description of these types of arrangements in the Environmental Credits and Related Regulatory Obligations accounting policy disclosed in Note 2 to our accompanying consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, of our December 31, 2023 Annual Report on Form 10-K. For both arrangements and the related commitments, see also our "Cash Requirements" section below.

Debt Ratings

We receive debt ratings from the major ratings agencies in the U.S. In determining our debt ratings, the agencies consider a number of qualitative and quantitative items including, but not limited to, commodity pricing levels, our liquidity, asset quality, reserve mix, debt levels and seniorities, cost structure, planned asset sales and production growth opportunities.

There are no "rating triggers" in any of our contractual debt obligations that would accelerate scheduled maturities should our debt rating fall below a specified level. However, a downgrade could adversely impact our interest rate on new credit facility borrowings and the ability to economically access debt markets in the future. Additionally, any rating downgrades may increase the likelihood of us having to post additional letters of credit or cash collateral under certain contractual arrangements.

Cash Flows

The following table sets forth a summary of our consolidated cash flows (in millions):

Consolidated
	Three Months Ended March 31,
	2024		2023
Cash Flow Data:
Operating activities	$	166.7	$	395.1
Investing activities	(41.6)		(222.1)
Financing activities	(193.9)		(149.3)
Net (decrease) increase	$	(68.8)	$	23.7

Cash Flows from Operating Activities

Net cash provided by operating activities was $166.7 million for the three months ended March 31, 2024, compared to $395.1 million for the comparable period of 2023. Decreases were a result of cash receipts from customers and cash payments to suppliers and for salaries resulting in a net $259.8 million decrease in cash provided by operating activities, partially offset by a decrease in cash paid for debt interest of $30.5 million.

Cash Flows from Investing Activities

Net cash used in investing activities was $41.6 million for the three months ended March 31, 2024, compared to $222.1 million in the comparable period of 2023. The decrease in cash flows used in investing activities was primarily due to a $164.0 million decrease in purchases of property, plant and equipment, substantially driven by maintenance projects associated with the Tyler turnaround in 2023, $3.6 million of insurance proceeds in 2024 and payments of $12.3 million for equity interests investments and other in 2023.

Cash Flows from Financing Activities

Net cash used in financing activities was $193.9 million for the three months ended March 31, 2024, compared to $149.3 million in the

Management's Discussion and Analysis

comparable 2023 period. The increase in cash used was primarily due to net payments from product and other financing arrangements of $189.7 million for the three months ended March 31, 2024 compared to net proceeds of $98.9 million in the comparable 2023 period, the receipt of settlement proceeds of $58.0 million during the first quarter of 2023 associated with the termination of the J. Aron Supply & Offtake Agreements and origination of the Citi Inventory Intermediation Agreement (as defined in Note 7 of the condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q) and payment of $10.9 million of deferred financing costs primarily related to the issuance of the Delek Logistics 2029 Notes.

These increases in cash flows were partially offset by the receipt of net proceeds of $132.3 million from the Delek Logistics' public offering of common units in the three months ended March 31, 2024 and net proceeds from term debt of $116.3 million for the three months ended March 31, 2024 compared to net payments on term debt of $6.1 million in the comparable 2023 period, primarily related to the issuance of the Delek Logistics 2029 Notes and the related repayment of the Delek Logistics Term Loan Facility and Delek Logistics 2025 Notes and a decrease in net payments on long-term revolvers of $59.6 million.

Capital Spending

A key component of our long-term strategy is our capital expenditure program. The following table summarizes our actual capital expenditures for the three months ended March 31, 2024, by operating segment and major category (in millions):

	2024 Forecast		Three Months Ended March 31, 2024 Actual

(1) Expected interest payments on debt outstanding at March 31, 2024. Floating interest rate debt is calculated using March 31, 2024 rates. For additional information, see Note 8 to the condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q.

(2) Amounts reflect future estimated lease payments under operating leases having remaining non-cancelable terms in excess of one year as of March 31, 2024.

(3) We have purchase commitments to secure certain quantities of crude oil, finished product and other resources used in production at both fixed and market prices. We have estimated future payments under the market-based agreements using current market rates. Excludes purchase commitments in buy-sell transactions which have matching notional amounts with the same counterparty and are generally net settled in exchanges.

(4) Balances consist of obligations under RINs product financing arrangements, as described in Note 11 to the condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q and further discussed in the ''Environmental Credits and Related Regulatory Obligations" accounting policy included in Note 2 to our consolidated financial statements in Item 8. Financial Statements and Supplementary Data, of our December 31, 2023 Annual Report on Form 10-K.

(5) Balances consist of contractual obligations under agreements with third parties (not including Delek Logistics) for the transportation of crude oil to our refineries.

(6) Balances consist of contractual obligations under the Citi Inventory Intermediation Agreement, including principal obligation for the Baseline Volume Step-Out Liability and other recurring fees. For additional information, see Note 7 to the condensed consolidated financial statements in Item 1. Financial Statements, of this Quarterly Report on Form 10-Q.

Other Cash Requirements

Our material short-term cash requirements under contractual obligations are presented above, and we expect to fund the majority of those requirements with cash flows from operations. Our other cash requirements consisted of operating activities and capital expenditures. Operating activities include cash outflows related to payments to suppliers for crude and other inventories (which are largely reflected in our contractual purchase commitments in the table above) and payments for salaries and other employee related costs. Cash outlays in the first quarter of 2024 are planned to include incentive compensation payments that were earned and accrued in 2023. In line with our long-term sustainable strategy, future cash requirements will include initiatives to build on our long-term sustainable business model, ESG initiatives and sum of the parts initiatives.

Refer to the cash flow section for our operating activities spend during the three months ended March 31, 2024. While many of the expenses related to the operating activities are variable in nature, some of the expenditures can be somewhat fixed in the short-term due to forward planning on our level of activity.

Refer to the 'Capital Spending' section for our capital expenditures for the three months ended March 31, 2024 and our anticipated cash requirements for planned capital expenditures for the full year 2024.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Changes in commodity prices (mainly crude oil and refined products) and interest rates are our primary sources of market risk. When we make the decision to manage our market exposure, our objective is generally to avoid losses from adverse price changes, realizing we will not obtain the gains of beneficial price changes.

53 |

Management's Discussion and Analysis

Price Risk Management Activities

At times, we enter into the following instruments/transactions in order to manage our market-indexed pricing risk: commodity derivative contracts which we use to manage our price exposure to our inventory positions, future purchases of crude oil and ethanol, future sales of refined products or to fix margins on future production; and future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs obligations and meet the definition of derivative instruments under Accounting Standards Codification ("ASC") 815, Derivatives and Hedging ("ASC 815"). In accordance with ASC 815, all of these commodity contracts and future purchase commitments are recorded at fair value, and any change in fair value between periods has historically been recorded in the profit and loss section of our condensed consolidated financial statements. Occasionally, at inception, the Company will elect to designate the commodity derivative contracts as cash flow hedges under ASC 815. Gains or losses on commodity derivative contracts accounted for as cash flow hedges are recognized in other comprehensive income on the condensed consolidated balance sheets and, ultimately, when the forecasted transactions are completed in net revenues or cost of materials and other in the condensed consolidated statements of income.

The following table sets forth information relating to our open commodity derivative contracts, excluding our trading derivative contracts (which are presented separately below), as of March 31, 2024 ($ in millions):

	Total Outstanding			Notional Contract Volume by Year of Maturity
Contract Description	Fair Value		Notional Contract Volume	2024
Contracts not designated as hedging instruments:
Crude oil price swaps - long (1)	$	5.9	21,211,000	21,211,000
Crude oil price swaps - short (1)	(14.5)		19,967,000	19,967,000
Inventory, refined product and crack spread swaps - long (1)	2.0		896,000	896,000
Inventory, refined product and crack spread swaps - short (1)	(3.7)		1,281,000	1,281,000
RINs commitment contracts - long (2)	(11.5)		161,850,000	161,850,000
Total	$	(21.8)

(1) Volume in barrels.

(2) Volume in RINs.

Interest Rate Risk

We have market exposure to changes in interest rates relating to our outstanding floating rate borrowings, which totaled approximately $1,508.3 million as of March 31, 2024. The annualized impact of a hypothetical one percent change in interest rates on our floating rate debt outstanding as of March 31, 2024 would be to change interest expense by approximately $15.1 million.

We also have interest rate exposure in connection with our Inventory Intermediation Agreement under which we pay a time value of money charge based on Secured Overnight Financing Rate ("SOFR").

Inflation

Inflationary factors, such as increases in the costs of our inputs, operating expenses, and interest rates may adversely affect our operating results. In addition, current or future governmental policies may increase or decrease the risk of inflation, which could further increase costs and may have an adverse effect on our ability to maintain current levels of gross margin and operating expenses as a percentage of sales if the prices at which we are able to sell our products and services do not increase in line with increases in costs.

Commodity Derivatives Trading Activities

We enter into active trading positions in a variety of commodity derivatives, which include forward physical contracts, swap contracts, and futures contracts. These trading activities are undertaken by using a range of contract types in combination to create incremental gains by capitalizing on crude oil supply and pricing seasonality. These contracts are classified as held for trading and are recognized at fair value with changes in fair value recognized in the income statement. We had no outstanding trading commodity derivative contracts as of March 31, 2024.

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 February 28, 2024 (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, 2023 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"). 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.

Accounting Pronouncements Not Yet Adopted

ASU 2023-09, Income Taxes(Topic 740): Improvements to Income Tax Disclosures

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 Income Taxes(Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). The standard is intended to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The amendments in this ASU are effective for annual periods beginning after December 15, 2024, with early adoption permitted, and should be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the provisions of the amendments and the impact on its future condensed consolidated financial statements, but does not currently expect adopting this new guidance will have a material impact on our condensed consolidated financial statements and related disclosures.

ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the chief decision maker ("CODM") and included within each reported measure of a segment's profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and should be applied retrospectively to all prior periods presented in the financial statements. The adoption of ASU 2023-07 should not have a material impact on our condensed consolidated financial statements and related disclosures. See Note 2 for further information.

ASU 2023-06, Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative

In October 2023, the FASB issued ASU 2023-06 Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative ("ASU 2023-06"). The main provision of ASU 2023-06 is to clarify or improve disclosure and presentation requirements of a variety of topics, which will allow users to more easily compare entities subject to the SEC's existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the FASB accounting standard codification with the SEC's regulations. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is currently evaluating the provisions of the amendments and the impact on its future condensed consolidated financial statements, but does not currently expect adopting this new guidance will have a material impact on our condensed consolidated financial statements and related disclosures.

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 9); and

•intercompany eliminations.

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 includes 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. In addition, the refining segment includes our wholesale crude operations.

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.

Retail Segment

Our retail segment consists of 250 owned and leased convenience store sites as of March 31, 2024, 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, which is transferred to the retail segment at prices substantially determined by reference to published commodity pricing information.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share (or "EPS") is computed by dividing net income (loss) 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 15 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.

Delek Logistics

Delek Logistics

Delek Logistics is a publicly traded limited partnership formed by Delek in 2012 that owns and operates crude oil, refined products and natural gas logistics and marketing assets as well as water disposal and recycling assets. A substantial majority of Delek Logistics' assets are integral to Delek’s refining and marketing operations. As of March 31, 2024, we owned a 72.7% interest in Delek Logistics, consisting of 34,311,278 common limited partner units and the non-economic general partner interest. The limited partner interests in Delek Logistics not owned by us are reflected in net income attributable to non-controlling interest in the accompanying condensed consolidated statements of income and in non-controlling interest in subsidiaries in the accompanying condensed consolidated balance sheets.

On March 12, 2024, Delek Logistics completed a public offering of its common units in which it sold 3,584,416 common units (including an overallotment option of 467,532 common units) to the underwriters of the offering at a price to the public of $38.50 per unit. The proceeds received from this offering (net of underwriting discounts, commissions and expenses) were $132.3 million and were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility (defined below). Underwriting discounts totaled $5.5 million.

As a result of this common unit issuance and our resulting Delek Logistics ownership change, we adjusted additional paid-in capital and equity attributable to Delek Logistics’ non-controlling interest holders to reallocate Delek Logistics' equity among its unitholders.

Delek Logistics is a VIE, as defined under GAAP, and is consolidated into our condensed consolidated financial statements, representing our logistics segment. The assets of Delek Logistics can only be used to settle its own obligations and its creditors have no recourse to our assets. Exclusive of intercompany balances and the marketing agreement intangible asset between Delek Logistics and Delek which are eliminated in consolidation, the Delek Logistics condensed consolidated balance sheets are included in the condensed consolidated balance sheets of Delek.

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.

Distributions received from WWP are first applied to service the debt of HoldCo's wholly owned finance LLC, 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 March 31, 2024, 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 March 31, 2024 and December 31, 2023, Delek's HoldCo investment balance totaled $60.8 million and $51.4 million, 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 March 31, 2024 and December 31, 2023, Delek's investment balance in Red River totaled $140.0 million and $141.1 million, respectively.

In addition to Red River, Delek Logistics has two other pipeline joint ventures in which 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 and a 33% membership interest in Andeavor Logistics Rio Pipeline LLC which operates the other pipeline system. As of March 31, 2024 and December 31, 2023, Delek Logistics' investment balance in these joint ventures was $98.2 million and $100.3 million.

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 March 31, 2024 and December 31, 2023, Delek's investment balance in these joint ventures was $71.3 million and $67.9 million, respectively.

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.

On December 21, 2023, DKTS amended the Inventory Intermediation Agreement to among other things, (i) extend the term of the Inventory Intermediation Agreement from December 30, 2024 to January 31, 2026, (ii) reduce Citi’s unilateral term extension option from a twelve month extension period to a six month extension period and (iii) increase the amount of the payment deferral mechanism from $70 million to $250 million. As of March 31, 2024 and December 31, 2023, we had letters of credit outstanding of $185.0 million and $230.0 million, respectively, 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 March 31, 2024 and December 31, 2023, the volumes subject to the Inventory Intermediation Agreement totaled 5.5 million barrels and 5.4 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 Accounting Standards Codification ("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 sheets 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 sheets.

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 losses attributable to changes in fair value due to commodity-index price totaling $81.8 million and gains totaling $12.7 million during the three months ended March 31, 2024 and 2023, respectively.

The Additional 2029 Notes were issued under the same indenture as the Delek Logistics 2029 Notes and formed a part of the same series of notes as the Delek Logistics 2029 Notes. The net proceeds were used to repay a portion of the outstanding borrowings under the Delek Logistics Revolving Facility.

The Delek Logistics 2029 Notes are general unsecured senior obligations of the Co-issuers and are unconditionally guaranteed jointly and severally on a senior unsecured basis by Delek Logistics’ subsidiaries other than Finance Corp. and will be unconditionally guaranteed on the same basis by certain of Delek Logistics’ future subsidiaries. The Delek Logistics 2029 Notes rank equal in right of payment with all existing and future senior indebtedness of the Co-issuers, and senior in right of payment to any future subordinated indebtedness of the Co-issuers. Delek Logistics recorded $10.4 million of debt issuance costs which will be amortized over the term of the Delek Logistics 2029 Notes and included in interest expense in the condensed consolidated statements of income. The Delek Logistics 2029 Notes will mature on March 15, 2029, and interest is payable semi-annually in arrears on each March 15 and September 15, commencing September 15, 2024.

At any time prior to March 15, 2026, the Co-issuers may redeem up to 35% of the aggregate principal amount of the Delek Logistics 2029 Notes with the net cash proceeds of one or more equity offerings by Delek Logistics at a redemption price of 108.625% of the redeemed principal amount, plus accrued and unpaid interest, if any, subject to certain conditions and limitations. Prior to March 15, 2026, the Co-issuers may also redeem all or part of the Delek Logistics 2029 Notes at a redemption price of the principal amount plus accrued and unpaid interest, if any, plus a "make whole" premium, subject to certain conditions and limitations. In addition, beginning on March 15, 2026, the Co-issuers may, subject to certain conditions and limitations, redeem all or part of the Delek Logistics 2029 Notes, at a redemption price of 104.313% of the redeemed principal for the twelve-month period beginning on March 15, 2026, 102.156% for the twelve-month period beginning on March 15, 2027, and 100.00% beginning on March 15, 2028 and thereafter, plus accrued and unpaid interest, if any.

In the event of a change of control, accompanied or followed by a ratings downgrade within a certain period of time, subject to certain conditions and limitations, the Co-issuers will be obligated to make an offer for the purchase of the Delek Logistics 2029 Notes from holders at a price equal to 101.00% of the principal amount thereof, plus accrued and unpaid interest.

As of March 31, 2024, the effective interest rate was 8.81%.

Delek Logistics 2028 Notes

On May 24, 2021, Delek Logistics and Finance Corp. issued general unsecured senior obligations comprised of $400.0 million in aggregate principal amount of 7.125% senior notes maturing June 1, 2028 ("the Delek Logistics 2028 Notes"). The Delek Logistics 2028 Notes are unconditionally guaranteed jointly and severally on a senior unsecured basis by Delek Logistics’ subsidiaries (other than Finance Corp.) and will be unconditionally guaranteed on the same basis by certain of Delek Logistics’ future subsidiaries. Interest is payable semi-annually in arrears on June 1 and December 1. As of March 31, 2024, the effective interest rate was 7.39%.

Delek Logistics 2025 Notes

In May 2018, Delek Logistics and Finance Corp. issued general unsecured senior obligations comprised of $250.0 million in aggregate principal of 6.75% senior notes maturing on May 15, 2025 ("the Delek Logistics 2025 Notes"). Concurrent with the issuance of the Delek Logistics 2029 Notes, Delek Logistics made a cash tender offer (the "Offer") for all of the outstanding Delek Logistic 2025 Notes with a conditional notice of full redemption for the remaining balance not received from the Offer. The Company received tenders from holders of approximately $156.2 million in aggregate principal amount. All the remaining Delek Logistic 2025 Notes were redeemed by March 29, 2024, pursuant to the notice of conditional redemption. Debt extinguishment costs were $1.5 million and are recorded in interest expense, net in the accompanying condensed consolidated statements of income.

Guarantees Under Revolver and Term Facilities

The obligations of the borrowers under the Delek Term Loan Credit Facility and the Delek Revolving Credit Facility are guaranteed by Delek and each of its direct and indirect, existing and future, wholly-owned domestic subsidiaries, subject to customary exceptions and limitations, and excluding Delek Logistics Partners, LP, Delek Logistics GP, LLC, and each subsidiary of the foregoing (collectively, the "MLP Subsidiaries"). Borrowings under the Delek Term Loan Credit Facility and the Delek Revolving Credit Facility are also guaranteed by DK Canada Energy ULC, a British Columbia unlimited liability company and a wholly-owned restricted subsidiary of Delek.

The obligations under the Delek Logistics Revolving Facility are secured by first priority liens on substantially all of Delek Logistics' tangible and intangible assets.

Restrictive Terms and Covenants

Under the terms of our debt facilities, we are required to comply with usual and customary financial and non-financial covenants. Certain of our debt facilities contain limitations on future transactions such as incurrence of additional indebtedness, investments, affiliate transactions, asset acquisitions or dispositions, and dividends or distributions. As of March 31, 2024, we were in compliance with covenants on all of our debt instruments.

Some of Delek's subsidiaries have restrictions in their respective credit facilities limiting their use of assets. As of March 31, 2024, we had no subsidiaries with restricted net assets which would prohibit earnings from being transferred to the parent company for its use.

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 Renewable Identification Numbers ("RINs") 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 months ended March 31, 2024, 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 March 31, 2024, 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 March 31, 2024 and December 31, 2023. 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 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, and our Inventory Intermediation Agreement. 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.

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 9) are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service.

Our environmental credits obligation includes the Consolidated Net RINs Obligation, as well as other environmental credit obligation positions subject to fair value accounting pursuant to our accounting policy. The environmental credits obligation 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 condensed consolidated statements of income. With respect to our Consolidated Net RINs Obligation, we recognized no gain on changes in fair value for the three months ended March 31, 2024 and a gain totaling $0.3 million for the three months ended March 31, 2023, primarily attributable to changes in the market prices of the underlying credits that occurred at the end of each quarter.

We elected to account for our Inventory Intermediation 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, 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 condensed consolidated statements of income. See Note 7 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 $391.4 million, respectively, as of March 31, 2024, and $400.0 million and $380.4 million, respectively, at December 31, 2023.

Also, the fair value of the Delek Logistics 2029 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 $650.0 million and $664.3 million, respectively, as of March 31, 2024.

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):

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 March 31, 2024 and December 31, 2023, $5.7 million and $1.8 million, respectively, of cash collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty. See Note 9 for further information regarding derivative instruments.

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 U.S. 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 March 31, 2024, we have recorded an environmental liability of approximately $113.4 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 $2.9 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 March 31, 2024 and December 31, 2023 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 March 31, 2024. 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 March 31, 2024 and December 31, 2023, 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 Renewable Fuel Standard - 2 ("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.

Income Taxes	3 Months Ended
	Mar. 31, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesUnder ASC 740, Income Taxes (“ASC 740”), we generally use an estimated annual tax rate to record income taxes. For interim financial reporting, except in specified cases, the quarterly income tax provision aligns with the estimated annual tax rate, updated each quarter based on revised full-year pre-tax book earnings. In certain situations, the estimated annual tax rate may distort the interim income tax provision due to significant permanent differences. In such cases, the interim income tax provision is based on the year-to-date effective tax rate, adjusting for permanent differences proportionally. In the three months ended March 31, 2024, income taxes were calculated based on the year-to-date effective tax rate. In the three months ended March 31, 2023, income taxes were calculated based on the estimated annual tax rate. Our effective tax rate was 22.2% and 18.0% for the three months ended March 31, 2024 and 2023, 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 months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily due to an decrease in quarter to date pre-tax earnings and the impact of fixed dollar favorable permanent adjustments on the quarter

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 February 28, 2024 (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, 2023 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"). 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.

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 9); and

•intercompany eliminations.

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.
