| Amendment Description | This Amendment No. 1 to Form 8-K (this "Amendment") amends the Current Report on Form 8-K furnished by Delek US Holdings, Inc. on August 5, 2026 (the "Original Form 8-K"). The Original Form 8-K correctly included disclosure under Item 2.02, "Results of Operations and Financial Condition," and Item 9.01, "Financial Statements and Exhibits." This Amendment is being filed solely to correct the EDGAR Item designation associated with the Original Form 8-K, which excluded Item 2.02 from the EDGAR Item designation. No changes have been made to the disclosure contained in the Original Form 8-K, including the earnings release furnished as Exhibit 99.1, and this Amendment does not modify, update or supplement any information contained in the Original Form 8-K. |
