Operating expenses increased $370 million in the second quarter and $629 million in the first six months of 2026. The primary driver was the October 2025 acquisition of WRB, while lower costs after the Los Angeles Refinery ceased operations partially offset the increase. Depreciation and amortization decreased 28% in the second quarter and 29% in the first six months because 2025 included depreciation for the Los Angeles Refinery. Corporate overhead and other costs decreased $28 million in the second quarter and $15 million in the first six months, primarily because of lower information-technology depreciation and lower proxy-solicitation advisory fees.
