Delek US vs. Par Pacific: Which Energy Stock Is a Better Buy in 2026?

The article compares two independent refiners: Delek US and Par Pacific. Delek US operates four refineries across Texas, Arkansas, and Louisiana with a 63.3% stake in Delek Logistics, but faces high leverage (11.7x debt-to-equity), declining revenue, and regulatory uncertainty. Par Pacific operates four facilities across the Pacific Northwest and Hawaii with integrated retail operations, demonstrating stronger profitability (4.9% net margin), lower leverage (0.8x debt-to-equity), and superior cash generation ($296.5M free cash flow). The author recommends Par Pacific as the better 2026 investment due to its niche market positioning, operational momentum, and cleaner financial profile.
