Included in the Inventory Intermediation Agreement are cost of financing associated with the value of the inventory and other periodic charges, which we include in interest expense, net in the condensed consolidated statements of income. In addition to the cost of financing charges, we have other intermediation fees which include market structure settlements, where we may pay or receive amounts based on market conditions and volumes subject to the intermediation agreement. These market structure settlements are recorded in cost of materials and other in the condensed consolidated statements of income. The following table summarizes these fees (in millions):

On December 22, 2022, Delek entered into an inventory intermediation agreement ("Inventory Intermediation Agreement") with Citigroup Energy Inc. ("Citi") in connection with DK Trading & Supply, LLC (“DKTS”), an indirect subsidiary of Delek. Pursuant to the Inventory Intermediation Agreement, Citi will (i) purchase from and sell to DKTS crude oil and other petroleum feedstocks in connection with refining processing operations at El Dorado, Big Spring, and Krotz Springs, (ii) purchase from and sell to DKTS all refined products produced by such refineries other than certain excluded products and (iii) in connection with such purchases and sales, DKTS will enter into certain market risk hedges in each case, on the terms and subject to certain conditions.

On December 21, 2023, DKTS amended the Inventory Intermediation Agreement to among other things, (i) reduce Citi’s unilateral term extension option from a twelve month extension period to a six month extension period and (ii) increase the amount of the payment deferral mechanism from $70 million to $250 million. On February 21, 2025, DKTS amended the Inventory Intermediation Agreement to, among other things, (i) extend the term of the Inventory Intermediation Agreement from January 31, 2026 to January 31, 2027 and (ii) include a mechanism for DKTS to nominate each month whether to include volumes related to the Krotz Springs refinery for funding under the Inventory Intermediation Agreement. As of June 30, 2025, and December 31, 2024, we had letters of credit outstanding of $255.0 million and $200.0 million, respectively, supporting the Inventory Intermediation Agreement.

The Inventory Intermediation Agreement provides for the lease to Citi of crude oil and refined product storage facilities. At the inception of the Inventory Intermediation Agreement, we transferred title to a certain number of barrels of crude and other inventories to Citi, and the Inventory Intermediation Agreement requires the repurchase of the remaining inventory (including certain "Base Layer Volumes") at termination. As of June 30, 2025, and December 31, 2024, the volumes subject to the Inventory Intermediation Agreement totaled 5.4 million barrels and 5.5 million barrels, including Base Layer Volumes associated with our non-current inventory intermediation obligation of 5.5 million barrels.

The Inventory Intermediation Agreement is accounted for as an inventory financing arrangement under the fair value election provided by ASC 815 Derivatives and Hedging ("ASC 815") and ASC 825, Financial Instruments ("ASC 825"). Therefore, the crude oil and refined products barrels subject to the Inventory Intermediation Agreement will continue to be reported in our condensed consolidated balance sheets until processed and sold to a third party. At each reporting period, we record a liability equal to the repurchase obligation to Citi at current market prices. The repurchase obligations associated with the Base Layer Volumes are reflected as non-current liabilities on our condensed consolidated balance sheets to the extent that they are not contractually due within twelve months. The February 21, 2025, amendment did not change the base layer volumes of the Inventory Intermediation Agreement, and the liability associated with the base layer volumes is recorded as long-term in the accompanying condensed consolidated balance sheet. The remaining obligation resulting from our monthly activity, including long and short inventory positions valued at market-indexed pricing, are included in current liabilities (or receivables) on our condensed consolidated balance sheets.

Gains (losses) related to changes in fair value due to commodity-index price are recorded as a component of cost of materials and other in the condensed consolidated statements of income. With respect to the repurchase obligation, we recognized gains (losses) attributable to changes in fair value due to commodity-index price totaling $26.7 million and $30.0 million during the three and six months ended June 30, 2025, respectively, and $19.3 million and $(62.5) million during the three and six June 30, 2024, respectively. See Note 12 for discussion of gains and losses recognized from changes in fair value.
