Notes to Consolidated Financial Statements

  1. General

Organization

As used in this report, the terms "Delek Logistics Partners, LP," the "Partnership," "we," "us," or "our" may refer to Delek Logistics Partners, LP, one or more of its consolidated subsidiaries or all of them taken as a whole. The Partnership is a Delaware limited partnership formed in April 2012 by Delek US Holdings, Inc. ("Delek Holdings") and its subsidiary Delek Logistics GP, LLC, our general partner (our "general partner").

Description of Business

The Partnership provides gathering, pipeline and other transportation services primarily for crude oil and natural gas customers, storage, wholesale marketing and terminalling services primarily for intermediate and refined product customers, and water disposal and recycling services through its owned assets and joint ventures located primarily in the Permian Basin and other select areas in the Gulf Coast region. A significant portion of our existing assets are both integral to and dependent upon the success of Delek Holdings' refining operations, as many of our assets are contracted exclusively to Delek Holdings in support of its Tyler, Texas (the "Tyler Refinery"), El Dorado, Arkansas (the "El Dorado Refinery") and Big Spring, Texas (the "Big Spring Refinery").

  1. Accounting Policies

Basis of Presentation

Our consolidated financial statements include the accounts of the Partnership and its subsidiaries. We have evaluated subsequent events through the filing of this Annual Report on Form 10-K. Any material subsequent events that occurred during this time have been properly recognized or disclosed in our financial statements.

Use of Estimates

The preparation of our financial statements in conformity with United States ("U.S.") generally accepted accounting principles (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Reclassifications

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

Segment Reporting

We are an energy business focused on crude oil, natural gas, intermediate and refined products pipeline and storage activities and wholesale marketing, terminalling and offloading activities as well as water disposal and recycling. Management reviews operating results in four reportable segments:(i) gathering and processing;(ii) wholesale marketing and terminalling;(iii) storage and transportation; and(iv) investments in pipeline joint ventures. Operations that are not specifically included in the reportable segments are included in Corporate and other segment.

The assets and investments reported in the gathering and processing segment provide crude oil gathering and crude oil, natural gas, intermediate and refined products logistics services as well as support our water disposal and recycling operations in service to Delek Holdings' refining operations and independent third parties .

The wholesale marketing and terminalling segment provides marketing services for the refined products output of the Delek Holdings' refineries, engages in wholesale activity at our terminals and terminals owned by third parties, whereby we purchase light product for sale and exchange to third parties, and provides terminalling services at our refined products terminals to independent third parties and Delek Holdings.

The storage and transportation segment provides crude oil, intermediate and refined products transportation and storage services to Delek Holdings' refining operations and independent third parties.

The investments in pipeline joint ventures segment include the Partnership's joint ventures investments discussed in Note 13.

Segment reporting is discussed in more detail in Note 14.

Cash and Cash Equivalents

We maintain cash and cash equivalents in accounts with large U.S. financial institutions. Any highly liquid investments purchased with an original maturity of three months or less are considered to be cash equivalents.

Accounts Receivable

Accounts receivable primarily consists of trade receivables generated in the ordinary course of business. We perform on-going credit evaluations of our customers and generally do not require collateral on accounts receivable. Allowance for doubtful accounts is based on a combination of historical experience and specific identification methods. Delek Holdings accounted for more than 10% of our consolidated accounts receivable balance as of December 31, 2025 and 2024.

Inventory

Inventory consists of refined products and crude oil, which are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out ("FIFO") basis. We are not subject to concentration risk with specific suppliers, since our inventory purchases are commodities that are readily available from a large selection of suppliers.

Property, Plant and Equipment

Property, plant and equipment primarily consists of crude oil pipelines, tanks, terminals and gathering systems, and trucking assets. We also capitalize interest on capital projects. Property and equipment is stated at the lower of historical cost less accumulated depreciation, or fair value, if impaired. Assets acquired in conjunction with business acquisitions are recorded at estimated fair market value in accordance with the purchase method of accounting as prescribed in Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Acquisitions of net assets that do not constitute a business are accounted for by allocating the cost of the acquisition to individual assets acquired and liabilities assumed on a relative fair value basis and shall not give rise to goodwill as prescribed in ASC 805.

Betterments, renewals and extraordinary repairs that extend the life of an asset are capitalized. Maintenance and repairs are charged to expense as incurred.

Depreciation is computed using the straight-line method over management’s estimated useful lives of the related assets. The estimated useful lives are as follows:

Years
Buildings and building improvements15-40
Pipelines, tanks and terminals10-40
Other equipment3-15

Other Intangible Assets

Other intangible assets acquired in a business combination and determined to be finite-lived are amortized over their respective estimated useful lives. The finite-lived intangible assets are amortized on straight-line basis over the estimated useful lives of 4.8 to 86.6 years. The amortization expense, with the exception of the marketing contract intangible, is included in depreciation and amortization in the accompanying consolidated statements of income and comprehensive income. The marketing contract intangible was amortized on a straight-line basis over a 20-year period as a component of net revenues from affiliates. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment in connection with our evaluation of long-lived assets as events and circumstances indicate that the asset might be impaired. Refer to Note 9 Other Intangible Assets for further information.

Property, Plant and Equipment and Intangibles Impairment

Property, plant and equipment and intangibles are evaluated for impairment whenever indicators of impairment exist. In accordance with ASC 360, Property, Plant and Equipment and ASC 350, Intangibles - Goodwill and Other, we evaluate the realizability of these long-lived assets as events occur that might indicate potential impairment. In doing so, we assess whether the carrying amount of the asset is recoverable by estimating the sum of the future cash flows expected to result from the use of the asset, undiscounted and without interest charges. If the carrying amount is more than the recoverable amount, an impairment charge must be recognized based on the fair value of the asset.

F-10 |

Goodwill and Potential Impairment

Goodwill in an acquisition represents the excess of the aggregate purchase price over the fair value of the identifiable net assets. Goodwill is reviewed at least annually during the fourth quarter for impairment, or more frequently if indicators of impairment exist, such as disruptions in our business, unexpected significant declines in operating results or a sustained market capitalization decline. Goodwill is evaluated for impairment by comparing the carrying amount of the reporting unit to its estimated fair value. In accordance with Accounting Standards Updates ("ASU") 2017-04, Goodwill and Other (Topic 350); Simplifying the Test for Goodwill Impairment, goodwill impairment charge is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. In assessing the recoverability of goodwill, assumptions are made with respect to future business conditions and estimated expected future cash flows to determine the fair value of a reporting unit. We may consider inputs such as a market participant weighted average cost of capital, gross margin, capital expenditures and long-term growth rates based on historical information and our best estimate of future forecasts, all of which are subject to significant judgment and estimates. We may also consider a market approach in determining or corroborating the fair values of the reporting units using a multiple of expected future cash flows, such as those used by third-party analysts, which is also subject to significant judgment and estimates. If these estimates and assumptions change in the future, due to factors such as a decline in general economic conditions, competitive pressures on sales and margins and other economic and industry factors beyond management's control, an impairment charge may be required. A significant risk to our future results and the potential future impairment of goodwill is the volatility of the crude oil and the refined product markets which is often unpredictable and may negatively impact our results of operations in ways that cannot be anticipated and that are beyond management's control.

We may also elect to perform a qualitative impairment assessment of goodwill balances. The qualitative assessment permits companies to assess whether it is more likely than not (i.e., a likelihood of greater than 50%) that the fair value of a reporting unit is less than its carrying amount. If a company concludes that, based on the qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the company is required to perform the quantitative impairment test. Alternatively, if a company concludes based on the qualitative assessment that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it has completed its goodwill impairment test and does not need to perform the quantitative impairment test.

There wasno impairment during the years ended December 31, 2025 and 2024. During the year ended December 31, 2023, our annual assessment of goodwill resulted in an impairment of $14.8 million. Details of remaining goodwill balances by segment are included in Note 8.

Business Combinations

We recognize and measure the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date in accordance with the provisions of ASC 805. Any excess or deficiency of the purchase consideration when compared to the fair value of the net tangible assets acquired, if any, is recorded as goodwill or gain from a bargain purchase. The fair value of assets and liabilities as of the acquisition date are often estimated using a combination of approaches, including the income approach, which requires us to project future cash flows and apply an appropriate discount rate; the cost approach, which requires estimates of replacement costs and depreciation and obsolescence estimates; and the market approach which uses market data and adjusts for entity-specific differences. We use all available information to make these fair value determinations and engage third-party consultants for valuation assistance. The estimates used in determining fair values are based on assumptions believed to be reasonable but which are inherently uncertain. Accordingly, actual results may differ materially from the projected results used to determine fair value.

Equity Method Investments

For equity investments that are not required to be consolidated under the variable or voting interest model, we evaluate the level of influence we are able to exercise over an entity’s operations to determine whether to use the equity method of accounting. Our judgment regarding the level of influence over an equity method investment includes considering key factors such as our ownership interest, participation in policy-making and other significant decisions and material intercompany transactions. Equity investments for which we determine we have significant influence are accounted for as equity method investments. Amounts recognized for equity method investments are included in equity method investments in our consolidated balance sheets and adjusted for our share of the net earnings and losses of the investee, dividends received and cash distributions from the investee, which are separately stated in our consolidated statements of income and comprehensive income and our consolidated statements of cash flows. The carrying value of each equity method investment is evaluated for impairment when conditions exist that indicate it is more likely than not that an impairment may have occurred, which may include the loss of a key contract, lack of sustained earnings or a deterioration of market conditions, among others. When impairment triggers are present, the fair value of the equity method investment is estimated using the income approach and the market approach. The income approach utilizes a discounted cash flow model incorporating management’s expectations of the investee’s future revenue (including the throughput barrel per day sold and related reduced tariff rates), operating expenses and earnings before interest, taxes, depreciation and amortization, capital expenditures and an anticipated tax rate (“EBITDA”), the estimated long term growth rate and weighted average cost of capital (“WACC”) as the discount rate. The market approach uses estimated EBITDA multiples for guideline comparable companies to estimate the fair value of the equity method investment. An impairment loss is recorded in earnings in the current period if a decline in the value of an equity method investment is determined to be other than temporary. There wereno impairment losses recorded on equity method investments for the years ended December 31, 2025, 2024 or 2023. Equity method investments are reported as part of the investments in pipeline joint ventures segment. See Note 13 for further information on our equity method investments.

F-11 |

Variable Interest Entities

Our consolidated financial statements include the financial statements of our subsidiaries and variable interest entities ("VIE"), of which we are the primary beneficiary. We evaluate all legal entities in which we hold an ownership or other pecuniary interest to determine if the entity is a VIE. Variable interests can be contractual, ownership or other pecuniary interests in an entity that change with changes in the fair value of the VIE’s assets. If we are not the primary beneficiary, the general partner or another limited partner may consolidate the VIE, and we record the investment as an equity method investment.

Fair Value of Financial Instruments

The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of our assets and liabilities that fall under the scope of ASC 825, Financial Instruments ("ASC 825"), with the exception of our fixed rate debt.

Environmental Expenditures

It is our policy to accrue environmental and clean-up related costs of a non-capital nature when it is both probable that a liability has been incurred and the amount can be reasonably estimated. Environmental liabilities represent the current estimated costs to investigate and remediate contamination at sites where we have environmental exposure. This estimate is based on assessments of the extent of the contamination, the selected remediation technology and review of applicable environmental regulations, typically considering estimated activities and costs for 15 years, and up to 30 years if a longer period is believed reasonably necessary. Such estimates may require judgment with respect to costs, time frame and extent of required remedial and clean-up activities. Accruals for estimated costs from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study and include, but are not limited to, costs to perform remedial actions and costs of machinery and equipment that are dedicated to the remedial actions and do not have an alternative use. Such accruals are adjusted as further information develops or circumstances change. We discount environmental liabilities to their present value if payments are fixed or reliably determinable. Expenditures for equipment necessary for environmental issues relating to ongoing operations are capitalized. Estimated recoveries of costs from other parties are recorded on an undiscounted basis as assets when their realization is deemed probable. See Note 15 for further information on crude oil releases impacting our properties and related accruals.

Asset Retirement Obligations

We recognize liabilities which represent the fair value of a legal obligation to perform asset retirement activities, including those that are conditional on a future event, when the amount can be reasonably estimated. These obligations are related to the required cleanout of our pipelines and terminal tanks and removal of certain above-grade portions of our pipelines situated on right-of-way property.

The reconciliation of the beginning and ending carrying amounts of asset retirement obligations as of December 31, 2025 and 2024 is as follows (in thousands):

December 31,
20252024
Beginning balance$15,639$10,038
Acquisition6,0224,852
Liabilities settled—(171)
Accretion expense2,617920
Ending balance$24,278$15,639

In order to determine fair value, management must make certain estimates and assumptions including, among other things, projected cash flows, a credit-adjusted risk-free rate and an assessment of market conditions that could significantly impact the estimated fair value of the asset retirement obligation.

Revenue Recognition

Revenue is measured based on consideration specified in a contract with a customer. The Partnership recognizes revenue when it satisfies a performance obligation by transferring control over a product or by providing services to a customer.

Service, Product and Lease Revenues. Revenues for products sold are generally recognized upon delivery of product, which is when title and control of the product is transferred. Transaction prices for these products are typically at market rates for the product at the time of delivery. Service revenues are recognized as crude oil, intermediate and refined products are shipped through, delivered by or stored in our pipelines, trucks, terminals and storage facility assets, as applicable. We do not recognize product revenues for these services, as the product does not represent a promised good in the context of ASC 606, Revenue from Contracts with Customers ("ASC 606"). All service revenues are based on regulated tariff rates or contractual rates. Payment terms require customers to pay shortly after delivery and do not contain significant financing components. We exclude from revenue all taxes assessed by a governmental authority, including sales, use and excise taxes, that are both imposed on and concurrent with a specific revenue-producing transaction and collected on behalf of a customer.

F-12 |

Certain agreements for gathering, transportation, storage, terminalling, and offloading with Delek Holdings are considered leases under ASC 842. As part of the adoption of ASC 842, as lessee, we applied the permitted practical expedient to not separate lease and non-lease components under the predominance principle to designated asset classes associated with the provision of logistics services. We have determined that the predominant component of the related agreements currently in effect is the lease component. Therefore, the combined component is accounted for under the applicable lease accounting guidance. Refer to Note 5 and Note 16 for further information.

Up-Front payments to Customers. We record up-front payments to customers in accordance with ASC 606. We evaluate the nature of each payment, the rights and obligations under the related contract, and whether the payment meets the definition of an asset. When an asset is recognized for an up-front payment to a customer, the asset is amortized, as a reduction of revenue, in a manner that reflects the pattern and period over which the asset is expected to provide benefit.

Revenues Related to Reimbursements. In addition to the agreements noted above, we have cost reimbursement provisions in certain of our agreements with Delek Holdings and third-parties that provide for reimbursement to the Partnership for certain costs, including certain capital expenditures. Such reimbursements are recorded in other long-term liabilities and are amortized to revenue over the life of the underlying revenue agreement corresponding to the asset.

Cost of Materials and Other and Operating Expenses

Cost of materials and other includes(i) all costs of purchased refined products, additives and related transportation of such products,(ii)costs associated with the operation of our trucking assets, which primarily include allocated employee costs and other costs related to fuel, truck leases and repairs and maintenance, and(iii) the cost of pipeline capacity leased from a third-party.

Operating expenses include the costs associated with the operation of owned terminals and pipelines and terminalling expense at third-party locations, excluding depreciation and amortization. These costs primarily include outside services, allocated employee costs, repairs and maintenance costs and energy and utility costs. Operating expenses related to the wholesale business are excluded from cost of sales because they primarily relate to costs associated with selling the products through our wholesale business.

Depreciation and amortization is separately presented in our consolidated statements of income and disclosed by reportable segment in Note 14.

Deferred Financing Costs

Deferred financing costs are included in other non-current assets in the accompanying consolidated balance sheets and represent expenses related to issuing and amending our revolving credit facility. Deferred financing costs associated with our term loan facilities are included as a reduction to the associated debt balance in the accompanying consolidated balance sheets. These costs represent expenses related to issuing our long-term debt and obtaining our lines of credit. These amounts are amortized ratably over the remaining term of the respective financing and are included in interest expense in the accompanying consolidated statements of income and comprehensive income.

Leases

In accordance with ASC 842-20, Leases - Lessee("ASC 842-20"), we classify leases with contractual terms longer than twelve months as either operating or finance. Finance leases are generally those leases that are highly specialized or allow us to substantially utilize or pay for the entire asset over its useful life. All other leases are classified as operating leases.

We have noncancelable operating leases primarily associated with rights-of-way and transportation equipment. Certain leases also include options to purchase the leased equipment. Certain of our lease agreements include rates based on equipment usage. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

For all leases that include fixed rental rate increases, these are included in our fixed lease payments. Our leases may include variable payments, based on changes on price or other indices, which are expensed as incurred.

We calculate the total lease expense for the entire noncancelable lease period, considering renewals for all periods for which it is reasonably certain to be exercised, and record lease expense on a straight-line basis in the accompanying consolidated statements of income. Accordingly, a lease liability is recognized for these leases and is calculated to be the present value of the fixed lease payments, as defined by ASC 842-20, using a discount rate based on our incremental borrowing rate. A corresponding right-of-use asset is recognized based on the lease liability and adjusted for certain costs and prepayments. The right-of-use asset is amortized over the noncancelable lease period, considering renewals for all periods for which it is reasonably certain to be exercised. For substantially all classes of underlying assets, we have elected the practical expedient not to separate lease and non-lease components, which allows us to combine the components if certain criteria are met.

F-13 |

As a lessor under ASC 842, we may be required to re-classify existing operating leases to sales-type leases upon modification and related reassessment of the leases. The net investment in sales-type leases with related parties is recorded within lease receivable - affiliate and net lease investment - affiliate on the consolidated balance sheets. These amounts are comprised of the present value of the sum of the future minimum lease payments representing the value of the lease receivable and the unguaranteed residual value of the leased assets. We regularly monitor the condition and usage of leased assets during the lease term. This includes periodic inspections and assessments of the asset’s remaining useful life, physical condition, and market demand. By closely tracking these factors, we are better able to anticipate the potential impact on residual value and take proactive measures if necessary. Management assesses the net investment in sales-type leases for recoverability quarterly. See Note 16 for further information.

Income Taxes

We are not a taxable entity for federal income tax purposes or the income taxes of those states that follow the federal income tax treatment of partnerships. Instead, for purposes of these income taxes, each partner of the Partnership is required to take into account its share of items of income, gain, loss and deduction in computing its federal and state income tax liabilities, regardless of whether cash distributions are made to such partner by the Partnership. The taxable income reportable to each partner takes into account differences between the tax basis and fair market value of our assets and financial reporting basis of assets and liabilities, the acquisition price of such partner's units and the taxable income allocation requirements under the Partnership's Second Amended and Restated Agreement of Limited Partnership, as amended (the "Partnership Agreement").

We are subject to income taxes in certain states that do not follow the federal tax treatment of partnerships. These taxes are accounted for under the provisions of ASC 740, Income Taxes ("ASC 740"). This statement generally requires the Partnership to record deferred income taxes for the differences between the book and tax bases of its assets and liabilities, which are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred income tax expense or benefit represents the net change during the year in our deferred income tax assets and liabilities, exclusive of the amounts held in other comprehensive income.

GAAP requires management to evaluate uncertain tax positions taken by the Partnership. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the Internal Revenue Service. Management has analyzed the tax positions taken by the Partnership, and has concluded that there are no uncertain positions taken or expected to be taken. The Partnership is subject to routine audits by taxing jurisdictions.

Allocations of Net Income

Our Partnership Agreement contains provisions for the allocation of net income and loss to the unitholders. For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest.

Net Income per Limited Partner Unit

We use the two-class method when calculating the net income per unit applicable to limited partners, because we have more than one participating class of securities. Our participating securities consist of common units and preferred units.

The two-class method is based on the weighted-average number of common units outstanding during the period. Basic net income per unit applicable to common limited partners is computed by dividing limited partners’ interest in net income allocated to participating securities by the weighted-average number of outstanding common units. Undistributed earnings are allocated to our preferred unitholders and limited partners based on their respective ownership interests. During a period of net loss or negative undistributed earnings, the two-class method is not applicable.

Diluted net income per unit applicable to common limited partners includes the effects of potentially dilutive units on our common units. For the years ended December 31, 2025, 2024 and 2023, the only potentially dilutive units outstanding consisted of unvested phantom units.

Comprehensive Income

Comprehensive income for the years ended December 31, 2025, 2024 and 2023 was equivalent to net income.

  1. Acquisitions

Gravity Acquisition

On January 2, 2025, we purchased 100% of the limited liability company interests in Gravity Water Intermediate Holdings LLC from Gravity Water Holdings LLC (the "Seller") related to the Seller's water disposal and recycling operations in the Permian Basin and the Bakken (the “Gravity Acquisition”) for total consideration of $300.8 million, subject to customary adjustments for net working capital. The purchase price was comprised of $209.3 million in cash, consisting of a cash deposit of $22.8 million paid in December 2024, upon execution of the purchase agreement and $186.5 million paid at closing, and 2,175,209 of common units.

For the year ended December 31, 2025, we incurred $5.0 million in incremental direct acquisition and integration costs that principally consist of legal, advisory and other professional fees. Such costs are included in general and administrative expenses in the accompanying consolidated statements of income and comprehensive income.

Our consolidated financial and operating results reflect the Gravity Acquisition operations beginning January 2, 2025. Our results of operations included revenue and net income of $90.1 million and $29.2 million, respectively, for the period from January 2, 2025, through December 31, 2025, related to these operations.

This acquisition was accounted for using the acquisition method of accounting, whereby the purchase price is measured at acquisition date fair value of assets acquired and liabilities assumed.

Determination of Purchase Price

The table below presents the purchase price (in thousands):

Base purchase price:$291,561
Less: Adjusted Net Working Capital (as defined in the Gravity Acquisition Agreement)3,814
Plus: Various closing adjustments5,433
Adjusted purchase price$300,808
Cash paid$209,297
Fair value of common units issued (1)91,511
Purchase price$300,808

(1)The increase from the $85.0 million base purchase price outlined in the purchase agreement for the common unit consideration was driven by an appreciation in the common unit price.

Purchase Price Allocation

The following table summarizes the fair values of assets acquired and liabilities assumed in the Gravity Acquisition as of January 2, 2025 (in thousands):

Assets acquired:
Cash and cash equivalents$5,317
Accounts receivables16,433
Inventories1,851
Other current assets1,681
Property, plant and equipment191,485
Operating lease right-of-use assets107
Customer relationship intangible (1)66,271
Other intangibles (1)31,921
Other non-current assets59
Total assets acquired315,125
Liabilities assumed:
Accounts payable2,459
Accrued expenses and other current liabilities5,733
Current portion of operating lease liabilities54
Asset retirement obligations6,022
Operating lease liabilities, net of current portion49
Total liabilities assumed14,317
Fair value of net assets acquired$300,808

(1)The acquired intangible assets amount includes the following identified intangibles:

Customer relationship intangible that is subject to amortization with a fair value of $66.3 million, which will be amortized over approximately 32 years.

Rights-of-way intangibles are valued at $31.9 million, the majority of which have an indefinite life.

The fair value of property, plant and equipment was based on the combination of the cost and market approaches. Key assumptions in the cost approach include determining the replacement cost by evaluating recently published data and adjusting replacement cost for physical deterioration, functional and economic obsolescence. We used the market approach to measure the value of certain assets through an analysis of recent sales or offerings of comparable properties.

Customer relationships were valued using the income approach, with essential assumptions including projected revenues from these relationships, attrition rates, operating margins, and discount rates.

The fair values discussed above were based on significant inputs that are not observable in the market and, therefore, represent Level 3 measurements. For all other current assets and payables, their fair values were considered equivalent to their carrying amounts due to their short-term nature.

Unaudited Pro Forma Financial Information

The following table summarizes the unaudited pro forma financial information of the Partnership assuming the Gravity Acquisition had occurred on January 1, 2024. The unaudited pro forma financial information has been adjusted to give effect to certain pro forma adjustments that are directly related to this acquisition based on available information and certain assumptions that management believes are factually supportable. The most significant pro forma adjustments relate to (i) incremental interest expense associated with revolving credit facility borrowings incurred in connection with this acquisition, (ii) incremental depreciation resulting from the estimated fair values of acquired property, plant and equipment, (iii) incremental amortization resulting from the estimated fair value of the acquired customer relationship intangible and, (iv) transaction costs. The unaudited pro forma financial information excludes any expected cost savings or other synergies as a result of this acquisition. The unaudited pro forma financial information is not necessarily indicative of the results of operations that would have been achieved had this acquisition been effective as of the date presented, nor is it indicative of future operating results of the combined company. Actual results may differ significantly from the unaudited pro forma financial information.

H2O Midstream Acquisition

On September 11, 2024, we completed an acquisition in which we acquired 100% of the limited liability company interests in H2O Midstream Intermediate, LLC, H2O Midstream Permian LLC, and H2O Midstream LLC ("H2O Midstream Acquisition") from H2O Midstream Holdings, LLC. The H2O Midstream Acquisition included water disposal and recycling operations in the Midland Basin in Texas, for total consideration of $229.7 million, subject to customary adjustments for net working capital. The purchase price was comprised of $159.7 million in cash and $70.0 million of preferred units (“Preferred Units”). The cash portion was financed through a combination of cash on hand and borrowings under the DKL Credit Facility (as defined in Note 10 ).

This acquisition was accounted for using the acquisition method of accounting, whereby the purchase price is measured at acquisition date fair value of assets acquired and liabilities assumed.

(1)The acquired intangible assets amount includes the following identified intangibles:

Customer relationship intangible that is subject to amortization with a fair value of $26.3 million, which will be amortized over 13.4 years.

Rights-of-way intangibles are valued at $28.5 million, which have an indefinite life.

Favorable supply contract intangible that is subject to amortization with a fair value of $4.8 million which will be amortized over 4.8 years.

The fair value of property, plant and equipment was based on the combination of the cost and market approaches. Key assumptions in the cost approach include determining the replacement cost by evaluating recently published data and adjusting replacement cost for physical deterioration, functional and economic obsolescence. We used the market approach to measure the value of certain assets through an analysis of recent sales or offerings of comparable properties.

Customer relationships were valued using the income approach, with essential assumptions including projected revenues from these relationships, attrition rates, operating margins, and discount rates.

The fair values discussed above were based on significant inputs that are not observable in the market and, therefore, represent Level 3 measurements. For all other current assets and payables, their fair values were considered equivalent to their carrying amounts due to their short-term nature.

Wink to Webster Pipeline Investment Acquisition

On August 5, 2024, the Partnership acquired Permian Pipeline Holdings, LLC, which holds 50% equity interests in Wink to Webster Holdings, LLC ("W2W Holdings"), from a wholly owned subsidiary of Delek Holdings. W2W Holdings includes our 15.6% indirect interest in the Wink to Webster Pipeline, LLC joint venture ("Wink to Webster"), and related joint venture indebtedness. Wink to Webster owns and operates a long-haul crude oil pipeline system with origin points at Wink and Midland in the Permian Basin and delivery points at multiple Houston area locations. Total consideration was comprised of $83.9 million in cash (including $2.7 million post-closing adjustment), forgiveness of a $60.0 million receivable from Delek Holdings and 2,300,000 of common units representing limited partnership interest in us.

This acquisition was considered a transaction between entities under common control. Accordingly, the equity interests acquired were recorded at amounts based on Delek Holdings' historical carrying value as of the acquisition date. The carrying value of the equity interests as of the acquisition date was $81.1 million. Pursuant to common control guidance, we recorded a reduction to equity of $62.8 million, included in contributions in the accompanying consolidated statements of partners' equity (deficit), representing the net carrying amount of the equity interest acquired less the consideration paid. No value was assigned to the 2,300,000 common units issued. Prior periods have not been recast as these assets do not constitute a business in accordance with ASC 805.

Commercial Agreements

The Partnership has a number of long-term, fee-based commercial agreements with Delek Holdings under which we provide various services, including crude oil gathering and crude oil, intermediate and refined products transportation and storage services, and marketing, terminalling and offloading services to Delek Holdings. Most of these agreements have an initial term ranging from five toten years, which may be extended for various renewal terms at the option of Delek Holdings. The fees under each agreement are payable to us monthly by Delek Holdings or certain third parties to whom Delek Holdings has assigned certain of its rights and are generally subject to increase or decrease on July 1 of each year, by the amount of any change in various inflation-based indices, however, in no event will the fees be adjusted below the amount initially set forth in the applicable agreement. Under each of these agreements, we are required to maintain the capabilities of our pipelines and terminals, such that Delek Holdings may throughput and/or store, as the case may be, specified volumes of crude oil, intermediate and refined products.

On August 5, 2024, the Partnership amended and extended expired, or soon to be expired, commercial agreements with subsidiaries of Delek Holdings under which we provide various services, including crude oil gathering and crude oil, intermediate and refined products transportation and storage services, and marketing, terminalling and offloading services to Delek Holdings. These amendments required the embedded leases within these agreements to be reassessed under ASC 842. As a result, certain leases were reclassified from operating leases to sales-type leases (see Note 16 for further information on sales-type leases).

These agreements have an initial term offive toseven years, with the ability to extend for an additional five years at Delek Holdings' option and were effective as of July 1, 2024. The initial expiration dates for these agreements range from 2028 to 2036. Certain of these contracts have rate adjustments to be phased in through 2026.

Associated with such marketing agreement was a contract intangible with a carrying value of $97.9 million at the closing date of the assignment. This intangible was transferred to Delek Holdings in conjunction with the assignment.

  1. Revenues

We generate revenue by charging fees for gathering, transporting, offloading and storing crude oil and natural gas; for storing intermediate products and feed stocks; for water disposal and recycling services; for distributing, transporting and storing refined products; for marketing refined products output of Delek Holdings' Tyler and Big Spring refineries; and for wholesale marketing in the West Texas area. A significant portion of our revenue is derived from long-term commercial agreements with Delek Holdings, which provide for annual fee adjustments for increases or decreases in the CPI, PPI or the FERC index (refer to Note 4 for a more detailed description of these agreements). In addition to the services we provide to Delek Holdings, we also generate substantial revenue from crude oil, natural gas, intermediate and refined products transportation services for, and terminalling and marketing services to, and water disposal and recycling services to third parties primarily in Texas, New Mexico, Tennessee and Arkansas. Certain of these services are provided pursuant to contractual agreements with third parties. Payment terms require customers to pay shortly after delivery and do not contain significant financing components. Delek Holdings, directly or indirectly, accounted for 49.3%,55.0% and 55.3% of our total revenues for the years ended December 31, 2025, 2024 and 2023, respectively.

The majority of our commercial agreements with Delek Holdings meet the definition of a lease because: (1) performance of the contracts is dependent on specified property, plant or equipment and (2) it is remote that one or more parties other than Delek Holdings will take more than a minor amount of the output associated with the specified property, plant or equipment.

  1. Goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the identifiable net assets acquired and is not amortized. We perform an annual assessment of whether goodwill retains its value. This assessment is done more frequently if indicators of potential impairment exist. We performed our annual goodwill impairment review in the fourth quarter of 2025, 2024, and 2023.

For the years ended December 31, 2025 and 2024, we performed a qualitative assessment. The annual impairment review resulted in the determination that no indicators of impairment of goodwill were present.

For the year ended December 31, 2023, we performed a quantitative assessment for our Delaware Gathering reporting unit and a qualitative assessment for our other reporting units. Our 2023 testing of goodwill did not identify any impairments other than our Delaware Gathering reporting unit, which reported a goodwill impairment charge of $14.8 million. The impairment was primarily driven by the significant increases in interest rates and timing of system connections with our producer customers.

For the quantitative assessment, we estimated the value of each of the reporting unit using a discounted cash flows ("DCF") analysis. The significant assumptions that were used to develop the estimates of the fair values under the DCF method included management’s best estimates of the discount rate of 16% as well as estimates of future cash flows, which are impacted primarily by volume and EBITDA projections. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the annual goodwill impairment test will prove to be an accurate prediction of the future. The fair value measurements for the individual reporting units represent Level 3 measurements.

Accumulated goodwill impairment was $14.8 million as of December 31, 2025, 2024 and 2023.

As of December 31, 2025, 2024,and 2023, our goodwill by segment was $4.2 million, $7.5 million and $0.5 million, in our gathering and processing, wholesale marketing and terminalling and storage and transportation, respectively.

DKL Credit Facility

On October 13, 2022, the Partnership entered into a senior secured term loan with Fifth Third, as administrative agent and a syndicate of lenders with an original principal of $300.0 million (the "DKL Term Loan Facility"). On November 6, 2023, the Partnership entered into a First Amendment, a Second Amendment and a Third Amendment to the DKL Credit Facility (the "DKL Credit Facility"), (together, the “Amendments”) which among other things added a maturity acceleration clause which would accelerate the maturity of the DKL Term Facility to 180 days prior to the stated maturity date of the 2025 Notes if any of the 2025 Notes remained outstanding on that date. The DKL Term Facility had a final maturity date of and principal due on April 15, 2025. The outstanding principal balance of $281.3 million was paid on March 13, 2024 from a portion of the proceeds received with the issuance of the 2029 Notes as indicated below. At the Partnership's option, borrowings bore interest at either the Adjusted Term Secured Overnight Financing Rate benchmark (“SOFR”) or U.S. dollar prime rate, plus an applicable margin. The applicable margin was 2.50% for the first year of the DKL Term Loan Facility and 3.00% for the second year for U.S. dollar prime rate borrowings. SOFR rate borrowings included a credit spread adjustment of 0.10% to 0.25% plus an applicable margin of 3.50% for the first year and 4.00% for the second year. Debt extinguishment costs were $2.1 million for the year ended December 31, 2024, and were recorded in interest expense in the accompanying consolidated statements of income and comprehensive income.

On March 29, 2024, the Partnership entered into a Fourth Amendment to the amended and restated senior secured revolving credit agreement (the "DKL Revolving Facility") which among other things increased the U.S. Revolving Credit Commitments (as defined in the DKL 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, including up to $146.9 million for letters of credit and $31.9 million in swing line loans. This facility has a maturity date of October 13, 2027.

Borrowings under the DKL Revolving Facility bear interest at the election of the Partnership at either a U.S. dollar prime rate, plus an applicable margin ranging from 1.00% to 2.00% depending on the Partnership’s Total Leverage Ratio (as defined in the DKL Credit Agreement), or a SOFR rate plus a credit spread adjustment of 0.10% for one-month interest periods and 0.25% for three-month interest periods plus an applicable margin ranging from 2.00% to 3.00% depending on the Partnership’s Total Leverage Ratio. Unused revolving commitments under the DKL Revolving Facility incur a commitment fee that ranges from 0.30% to 0.50% depending on the Partnership’s Total Leverage Ratio, currently at 0.45% per annum. As of December 31, 2025 and December 31, 2024, the weighted average interest rate was 6.58% and 7.27%, respectively.

The DKL Credit Facility contains affirmative and negative covenants and events of default, which the Partnership considers customary and are similar to those in our predecessor DKL Credit Facility. We believe we were in compliance with all covenant requirements as of December 31, 2025. Under the financial covenants in the DKL Credit Facility, the Partnership cannot:

permit, as of the last day of each fiscal quarter, the Total Leverage Ratio (as defined in the DKL Credit Facility) to be greater than 5.25 to 1.00;

permit, as of the last day of each fiscal quarter, the Senior Leverage Ratio (as defined in the DKL Credit Facility) to be greater than 3.75 to 1.00; and

permit, as of the last day of each fiscal quarter, the interest coverage ratio to be equal to or less than 2.00 to 1.00.

The obligations under the DKL Revolving Facility are secured by first priority liens on substantially all of the Partnership’s and its subsidiaries’ tangible and intangible assets. The carrying value of outstanding borrowings under the DKL Revolving Facility as of December 31, 2025 and December 31, 2024 approximate their fair values. Our debt facilities contain affirmative and negative covenants and events of default the Partnership considers usual and customary. As of December 31, 2025, we were in compliance with covenants on all of our debt instruments.

The Related Party Revolving Credit Facility bore interest at Term SOFR (as defined in the Related Party Revolving Credit Facility) plus 3.00%.

  1. Equity Method Investments

The Partnership owns a 33% membership interest in Red River Pipeline Company LLC ("Red River"), a joint venture operated with Plains Pipeline, L.P, which owns and operates a crude oil pipeline running from Cushing, Oklahoma to Longview, Texas. Additionally, we havetwo 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. ("CP LLC") to operate one of these pipeline systems and a 33% membership interest in the entity formed with Andeavor Logistics RIO Pipeline LLC ("Andeavor Logistics") to operate the other pipeline system.

On August 5, 2024, the Partnership acquired Permian Pipeline Holdings, LLC, which holds a 50% equity interest in W2W Holdings. Our interest in W2W Holdings includes a 15.6% indirect interest in the Wink to Webster joint venture, and related joint venture indebtedness.

W2W Holdings was originally formed by Delek Holdings and MPLX Operations LLC to obtain financing and fund capital calls associated with its collective and contributed interests in Wink to Webster. Wink to Webster owns and operates a long-haul crude oil pipeline system with origin points at Wink and Midland in the Permian Basin and delivery points at multiple Houston area locations. We determined that W2W Holdings 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 W2W Holdings, and no single party has the power to direct the activities that most significantly impact W2W Holdings' economic performance.

Distributions received from WWP are first applied to service the debt of W2W Holdings wholly owned finance LLC, with excess distributions made to the W2W Holdings members as provided for in the W2W Holdings LLC Agreement and as allowed for under its debt agreements. The obligations of the W2W Holdings members under the W2W Holdings LLC Agreement are guaranteed by the parents of the member entities.

As of December 31, 2025, except for the guarantee of member obligations under the joint venture, we do not have other guarantees with or to W2W Holdings, nor any third-party associated with W2W Holdings contracted work. The Partnership's maximum exposure to any losses incurred by W2W Holdings is limited to its investment. The Partnership did not provide any financial support to equity method investments that it was not contractually obligated to provide during the years ended December 31, 2025, 2024, and 2023.

  1. Segment Data

We review operating results infour reportable segments:(i) gathering and processing;(ii) wholesale marketing and terminalling;(iii) storage and transportation; and(iv) investment in pipeline joint ventures. Operations that are not specifically included in the reportable segments are included in Corporate and other. The Partnership defines its segments based on how internally reported financial information is regularly reviewed by its chief operating decision maker ("CODM") to analyze financial performance, make decisions and allocate resources.

The CODM is the President of the Partnership. The CODM evaluates performance based on segment EBITDA for planning and forecasting purposes. The CODM considers budget to actual variances on a monthly basis when making decisions about allocation of operating and capital resources to each segment. Segment EBITDA is an important measure used by management to evaluate the financial performance of our core operations. As of the fourth quarter of 2025, we define segment EBITDA as net income (loss) before net interest expense, income tax expense, depreciation, amortization, and proportional interest, taxes, depreciation and amortization of equity method investments. Segment data for prior periods has been restated and is consistent with the current year presentation. A reconciliation of segment EBITDA to net Income is included in the tables below.

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

  1. 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.

Texas Department of Transportation Settlement

Beginning in August 2023, the Partnership was involved in litigation with the State of Texas Department of Transportation. The subject of the litigation was the expansion of the highway where the Partnership's Nettleton Station is situated. As a result of this expansion, two tanks owned by the Partnership were impacted. This litigation was settled in the second quarter of 2024 and resulted in the Partnership recovering $8.3 million in condemnation proceeds, which was recorded in other operating expense (income), net in the consolidated statements of income and comprehensive income. In 2025, we recovered an additional $4.3 million related to this settlement, which is recorded in other operating expense (income), net in the accompanying consolidated statements of income and comprehensive income.

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 Environmental Protection Agency (the "EPA"), the United States Department of Transportation, 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 and pollution prevention measures, as well as the safe operation of our pipelines and the safety of our workers and the public. The State of New Mexico promulgated new regulations to limit emissions from oil and gas operations in 2022. The cost to comply is not expected to be material. Numerous permits or other authorizations are required under these laws and regulations for the operation of our terminals, pipelines, salt wells, trucks 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, surface water and groundwater contamination, air pollution, personal injury and property damage allegedly caused by substances which we may have handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we may have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and we expect that there will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including the receipt and response to 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 to comply with existing and new requirements, as well as evolving interpretations and enforcement of existing laws and regulations.

Releases of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, or is not a reimbursable event under the Omnibus Agreement, subject us to substantial expenses, including costs to respond to, contain and remediate a release, to comply with applicable laws and regulations and to resolve claims by governmental agencies or other persons for personal injury, property damage, response costs, or natural resources damages.

Lessor

We are the lessor under certain agreements for gathering, transportation, storage, terminalling, and offloading with Delek Holdings. These agreements have remaining terms ranging from 2 to 11 years with renewal options of 5 years, and some agreements have multiple renewal options. Revenue from these leases are recorded in affiliate revenue in the consolidated statements of income. For details on Lease Revenue, see Note 5.

During 2024, we executed renewals to certain agreements between DKL and Delek Holdings. The renewals required the embedded leases within these agreements to be reassessed under ASC 842. As a result of these lease assessments, certain leases were reclassified from an operating lease to a sales-type lease. Accordingly, the underlying property, plant and equipment, net, and associated deferred revenue, if any, were derecognized and the present value of the future lease payments and the unguaranteed residual value of the assets were recorded as a net investment in sales-type lease during the respective periods.

The net investment in sales-type leases is recorded utilizing the estimated fair value of the underlying leased assets at contract modification date and are nonrecurring fair value measurements. The leased assets were valued using a cost method valuation approach which utilizes Level 3 inputs.

We recognized any billings in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in Net Revenues - Affiliate in the accompanying consolidated statements of income and comprehensive income.

We did not elect to use the practical expedient to combine lease and non-lease components for lessor arrangements. The tables below represent the portion of the contracts allocated to the lease component based on relative standalone selling price.

Lease income included in the consolidated statements of income and comprehensive income was as follows:

The following presents the consolidated financial statement impact of sales-type leases on commencement or modification date for the year ended December 31, 2024.

The amount recognized on commencement date was recorded in contributions in the consolidated statements of partners' equity (deficit), given the underlying agreements are between entities under common control.
