Delek Logistics Partners, LP

1. Organization and Basis of Presentation

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").

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 majority 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").

On January 2, 2025, we acquired 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”). See Note 2 for further information.

Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States 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 financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024 (our "Annual Report on Form 10-K"), filed with the U.S. Securities and Exchange Commission (the "SEC") on February 26, 2025 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 notes thereto for the year ended December 31, 2024 included in our Annual Report on Form 10-K.

All adjustments necessary for a fair presentation of the financial position and the results of operations for the interim periods presented have been included. All intercompany accounts and transactions have been eliminated. Such intercompany transactions do not include those with Delek Holdings or our general partner, which are presented as related parties in these accompanying condensed consolidated financial statements. 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.

2. Acquisitions

Gravity Acquisition

On January 2, 2025, we completed the Gravity Acquisition for a preliminary purchase price 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 on January 2, 2025 and 2,175,209 of common units.

For the three months ended March 31, 2025, we incurred $3.1 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 condensed 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 $22.9 million and $9.9 million, respectively, for the period from January 2, 2025 through March 31, 2025 related to these operations.

7 |

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 estimated purchase price (in thousands):

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

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

•Customer relationship intangible that is subject to amortization with a preliminary fair value of $50.7 million, which we estimate to be amortized over 10 to 25 years.

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

8 |

These fair value estimates are preliminary and therefore, the final fair value of assets acquired and liabilities assumed and the resulting effect on our financial position may change once all necessary information has become available and we finalize our valuations. To the extent possible, estimates have been considered and recorded, as appropriate, for the items above based on the information available as of March 31, 2025. We will continue to evaluate these items until they are satisfactorily resolved and adjust our purchase price allocation accordingly, within the allowable measurement period (not to exceed one year from the date of acquisition), as defined by ASC 805.

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 6 ).

For the three months ended March 31, 2025, we incurred $0.1 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 condensed consolidated statements of income and comprehensive income.

Our results of operations included revenue and net income of $16.5 million and $7.1 million, respectively, for the three months ended March 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 estimated purchase price (in thousands):

Purchase Price Allocation

The following table summarizes the preliminary fair values of assets acquired and liabilities assumed in the H2O Midstream Acquisition as of September 11, 2024 (in thousands):

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

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

•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 preliminary fair value of $4.8 million which will be amortized over a 4.8 years useful life.

These fair value estimates are preliminary and therefore, the final fair value of assets acquired and liabilities assumed and the resulting effect on our financial position may change once all necessary information has become available and we finalize our valuations. To the extent possible, estimates have been considered and recorded, as appropriate, for the items above based on the information available as of March 31, 2025. We will continue to evaluate these items until they are satisfactorily resolved and adjust our purchase price allocation accordingly, within the allowable measurement period (not to exceed one year from the date of acquisition), as defined by ASC 805.

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.

By acquiring Gravity and H20 Midstream, we intend to increase third-party revenue streams, diversify our customer and product mix, and expand our footprint in the Midland and Bakken basins, aligning with our strategic growth objectives.

3. Related Party Transactions

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.

8. 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 50% equity interests in W2W Holdings, from a wholly owned subsidiary of Delek Holdings. Our interest in W2W Holdings includes a 15.6% indirect interest in the Wink to Webster joint venture, and related joint venture indebtedness.

16 |

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 March 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's investment balances in these joint ventures were as follows (in thousands):

9. Segment Data

We aggregate our operating segments into four 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 segment. 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 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. EBITDA is an important measure used by management to evaluate the financial performance of our core operations. EBITDA is not a GAAP measure, but the components of EBITDA are computed using amounts that are determined in accordance with GAAP. A reconciliation of EBITDA to Net Income is included in the tables below. We define EBITDA as net income (loss) before net interest expense, income tax expense, depreciation and amortization expense, including amortization of marketing contract intangible, which is included as a component of net revenues in our accompanying condensed consolidated statements of income and comprehensive income.

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

17 |

The following is a summary of business segment operating performance as measured by EBITDA for the periods indicated (in thousands):

(1)Affiliate revenue for the wholesale marketing and terminalling segment is presented net of amortization expense pertaining to the marketing contract intangible of $1.8 million for the three months ended March 31, 2024. There wasno amortization recorded during the three months ended March 31, 2025 related to this intangible, as the associated agreement was terminated on August 5, 2024.

(2) Other segment items include general and administrative expense, other operating (income) loss and other income. Additionally, the wholesale marketing and terminalling segment includes amortization of the marketing contract intangible for the three months ended March 31, 2024.

(3) Capital spending includes additions on an accrual basis.

10. 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 income, net in the condensed consolidated statements of income and comprehensive income. In the first quarter of 2025, we recovered additional $4.3 million related to this settlement, which is recorded in other operating income, net in the accompanying condensed 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, saltwells, 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.

11. Leases

Lessor

We are the lessor under certain agreements for gathering, transportation, storage, terminalling, and offloading with Delek Holdings. Revenue from these leases are recorded in affiliate revenue in the condensed consolidated statements of income and comprehensive income. We elected the practical expedient to carry forward historical lease classification conclusions until a modification of an existing agreement occurs. Once a modification occurs, the amended agreement is required to be assessed under ASC 842, to determine whether a reclassification of the lease is required.

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 lease revenues.
