Investments in Pipeline Joint Ventures Segment

The Investments in Pipeline Joint Ventures segment relates to strategic Joint Venture investments, accounted for as equity method investments, to support the Delek Holdings operations in terms of offering connection to takeaway pipelines, alternative crude supply sources and flow of high-quality crude oil to the Delek Holdings refining system. As a result, Delek Holdings is a major shipper and customer on certain of the Joint Venture pipelines, with minimum volume commitment ("MVC") agreements, which cushion the Joint Venture entities during periods of low activity. The other Joint Venture owners are usually major shippers on the pipelines resulting in a majority of the revenue of the Joint Venture entities coming from MVC agreements with related entities.

Investments in pipeline joint ventures segment include the Partnership's joint ventures investments described in Note 8 of our condensed consolidated financial statements in Item 1, Financial Statements, of this Quarterly Report on Form 10-Q.

Refer to Consolidated Results of Operations above for details and discussion of the investments in pipeline joint ventures segment for the three and six months ended June 30, 2026.
