Reported earnings were $133 million for the third quarter of 2025 versus $877 million in the second quarter of 2025. Third-quarter earnings included pre-tax special item adjustments of $(948) million in the Refining segment and $(226) million in the Marketing and Specialties segment. Adjusted earnings for the third quarter were $1.0 billion versus adjusted earnings of $973 million in the second quarter.

•Midstream third-quarter 2025 pre-tax income decreased compared with the second quarter mainly due to lower margins, partially offset by higher volumes. These results included $30 million of additional depreciation associated with the retirement of assets at our Los Angeles Refinery.

•Chemicals pre-tax income increased mainly due to higher margins and lower costs which were largely driven by a decrease in turnaround spend.

•Refining adjusted pre-tax income increased mainly due to higher realized margins driven by higher market crack spreads, partially offset by higher environmental costs primarily associated with the planned idling of the Los Angeles Refinery.

•Marketing and Specialties adjusted pre-tax income decreased primarily due to lower margins.

•Renewable Fuels pre-tax results improved primarily due to higher realized margins, including inventory impacts, as well as higher international credits.

•Corporate and Other adjusted pre-tax loss decreased mainly due to timing of charitable contributions.

As of Sept. 30, 2025, the company had $2.0 billion of cash and cash equivalents, including assets held for sale, and $5.2 billion of committed capacity available under credit facilities.
