Refining segment income before interest and income taxes was $476 million for the third quarter of 2025 compared to a loss of $212 million for the third quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment charge of $46 million, the segment reported Adjusted EBITDA of $661 million for the third quarter of 2025 compared to $110 million for the third quarter of 2024. This increase was principally driven by higher adjusted refinery gross margins in both the West and Mid-Continent regions, which was inclusive of small refinery RINs waivers granted from the EPA. Adjusted refinery gross margin was $19.16 per produced barrel sold, a 78% increase compared to $10.79 for the third quarter of 2024. Crude oil charge averaged 639,050 barrels per day (“BPD”) for the third quarter of 2025 compared to 607,010 BPD for the third quarter of 2024. This increase was primarily a result of decreased turnaround activities during the third quarter of 2025.

Renewables segment loss before interest and income taxes was $55 million for the third quarter of 2025 compared to a loss of $23 million for the third quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment charge of $20 million, the segment reported Adjusted EBITDA of $(13) million in the third quarter of 2025 compared to $1 million in the third quarter of 2024. In the third quarter of 2025 we recognized incrementally more in value from the Producer’s Tax Credit (“PTC”).

The segment reported EBITDA of $29 million for the third quarter of 2025 compared to $22 million for the third quarter of 2024. This increase was primarily driven by higher margins and high-grading our mix of stores in the third quarter of 2025.

The segment reported EBITDA of $78 million for the third quarter of 2025 compared to $76 million in the third quarter of 2024. The increase was primarily driven by a FIFO benefit and better product mix, partially offset by an increase in operating expenses. During the third quarter of 2025, we recognized a FIFO benefit of $2 million compared to a FIFO charge of $27 million during the third quarter of 2024.

Midstream segment income before interest and income taxes was $98 million for the third quarter of 2025 compared to $80 million for the third quarter of 2024. The segment reported EBITDA of $114 million for the third quarter of 2025 compared to Adjusted EBITDA of $111 million for the third quarter of 2024.
