Company Description
Delek US Holdings, Inc. (NYSE: DK) is a diversified downstream energy company operating in the petroleum refineries industry within the manufacturing sector. According to the company’s public disclosures, Delek US focuses on petroleum refining, logistics and pipelines, and renewable fuels. Its operations are centered on converting crude oil into refined petroleum products and supporting those activities with midstream infrastructure and related services.
The company owns and operates independent refineries that serve transportation and industrial markets in the United States. Delek US states that its refining assets consist primarily of refineries operated in Tyler and Big Spring, Texas, El Dorado, Arkansas, and Krotz Springs, Louisiana, with a combined nameplate crude throughput capacity of 302,000 barrels per day. These refineries form the core of Delek US’s refining segment.
Business Segments and Operations
Delek US describes itself as having a refining segment and a logistics segment. The refining segment includes its refineries and related activities that generate refining margin based on the difference between sales and cost of sales, adjusted for operating expenses and depreciation and amortization. The company also uses non-GAAP measures such as refining margin, adjusted refining margin, and refining production margin to evaluate performance, as outlined in its earnings materials.
The logistics segment is conducted primarily through Delek Logistics Partners, LP (NYSE: DKL), which Delek US identifies as a growth-oriented master limited partnership focused on owning and operating midstream energy infrastructure assets. Delek US and its subsidiaries owned approximately 63%–63.6% (including the general partner interest) of Delek Logistics Partners, LP around mid-2025, based on company disclosures. Delek Logistics provides gathering, pipeline, transportation, storage, wholesale marketing, terminalling, water disposal, and recycling services for crude oil, intermediates, refined products, natural gas, and related products, primarily in and around the Permian Basin, the Delaware Basin, and other select areas in the Gulf Coast region.
In addition to refining and logistics, Delek US indicates that it has assets in renewable fuels. The company also references wholesale crude oil, intermediate, and refined products activities, as well as convenience stores retailing, in historical descriptions of its integrated energy business.
Relationship with Delek Logistics Partners, LP
Delek US highlights Delek Logistics Partners, LP as an important part of its overall business. Delek US owns the general partner interest and a majority limited partner interest in Delek Logistics and is also described as a significant customer of Delek Logistics. The logistics segment’s performance is influenced by activities such as dropdown transactions, acquisitions of midstream assets, and changes in wholesale margins, as reflected in the company’s earnings releases.
Delek US’s public communications note that Delek Logistics’ processing plants and midstream projects support producer customers and expand processing capacity in key basins. The company also discusses initiatives intended to increase the economic separation of Delek Logistics from Delek US as part of what it calls its “Sum of the Parts” and related initiatives.
Financial and Performance Metrics
Delek US regularly reports results using both GAAP and non-GAAP financial measures. The company identifies measures such as Adjusted net income (loss), Adjusted net income (loss) per share, EBITDA, Adjusted EBITDA, refining margin, adjusted refining margin, refining production margin, and net debt as important for assessing operating results and profitability. These measures are defined in the company’s earnings releases and reconciled to the most directly comparable GAAP measures.
Management states that these non-GAAP measures are used internally to evaluate segment performance, monitor leverage, and assess trends that may be obscured by infrequently occurring or non-cash items. Delek US cautions that non-GAAP measures have limitations and may be defined differently by other companies in the industry.
Regulatory Environment and Small Refinery Exemptions
Delek US operates within the U.S. regulatory framework for fuels, including the Renewable Fuel Standard. The company has publicly discussed Small Refinery Exemptions (SREs) granted by the U.S. Environmental Protection Agency (EPA) for past Renewable Volume Obligation (RVO) compliance periods. Delek US has indicated that these exemptions reduce certain compliance costs and have affected cost of materials and other items in its financial results.
In its communications, Delek US has welcomed EPA decisions granting a significant portion of its pending small refinery exemptions for years spanning multiple prior compliance periods. The company has linked these exemptions to its ability to maintain energy prices and jobs in regions where it operates and has referenced expectations related to monetization of historical SRE grants.

Delek Logistics Partners, LP separately declares quarterly cash distributions per common limited partner unit, with details on record dates and payment dates provided in its own press releases.
