HF Sinclair Q3 2026 earnings: refining margin surge drives big beat

October 28, 2026

HF Sinclair's Q3 2026 profit and revenue far exceeded forecasts, powered by a surge in refining margins versus a weak year-ago quarter.

Key takeaways

• Adjusted profit came in far above what analysts had modeled, and revenue also beat expectations — a sharp turnaround from the weak refining environment of a year earlier.
• The swing was driven almost entirely by refining margins, not by selling more fuel: the company’s margin on each barrel processed roughly tripled from a year ago, as tight supplies of gasoline and diesel pushed up what refiners could charge.
• A regulatory tailwind helped too — the EPA granted small-refinery exemptions from biofuel-blending (RINs) obligations for some of the company’s Mid-Continent and West plants, reducing compliance costs during the quarter.
• The renewables (biofuels) business also improved, benefiting from higher RINs credit prices and production tax credits, on top of the much stronger core refining results.
• Actual fuel processing volumes were slightly lower than a year ago because of planned maintenance at the company’s El Dorado, Kansas refinery, underscoring that the profit jump came from pricing and margins rather than throughput.
• Profitability margins over the trailing year — gross, operating and net — remain in line with a mid-sized refiner, but masked how much better this single quarter was than the rest of the trailing period; trailing-twelve-month revenue is still down from a year earlier even though this quarter’s revenue rose, reflecting how weak the comparable earlier quarters were.
• Return on equity over the trailing year sits near 20%, a sign the company is converting shareholder capital into profit efficiently, helped heavily by this quarter’s results.
• The company returned about $572 million to shareholders in the quarter through dividends and buybacks, and declared a regular quarterly dividend of $0.525 per share.
• Results included roughly $109 million in one-time costs tied to the planned retirement of the Mississauga, Ontario base oil refinery, a restructuring the company expects to largely complete in the second half of 2027.
• Higher income tax expense, up to $509 million for the quarter, partly offset the operating gains, a reminder that pretax strength doesn’t flow entirely to the bottom line.
