Management Comments

• "2025 has been a transformational year for DK in improving its cash flow profile through successful implementation of the Enterprise Optimization Plan, reducing the costs of Inventory Intermediation Agreements, and progressing its economic separation with Delek Logistics."
• "We are very proud of the continuous improvement culture we are building at Delek and look forward to driving incremental free cash flow improvement through continued operational excellence, cost optimization, and disciplined capital allocation."

Industry Context

StockSavvy.ai notes that Delek US's strong Q4 2025 performance, particularly in refining margins, aligns with a period of favorable crack spreads in the U.S. Gulf Coast, indicating a robust market environment for refiners. The continued expansion and record EBITDA from Delek Logistics, especially its focus on the Permian Basin's sour gas and water infrastructure, positions it well within the growing midstream sector, where demand for integrated services remains high. The company's emphasis on its Enterprise Optimization Plan and strategic separation from DKL reflects a broader industry trend towards operational efficiency and value realization through focused business units.
