Phillips 66 PSX Refining — Transfer of gross PP&E between segments

In the fourth quarter of 2025, we ceased fuel production and began idling facilities at our Los Angeles Refinery. The process of fully idling these facilities is ongoing while the redevelopment project plans continue through the review processes of the relevant state and local agencies. As a result, the carrying values of the associated net PP&E and intangible assets were depreciated to the estimated salvage value of $241 million at December 31, 2025. Total depreciation related to the Los Angeles Refinery assets for the three and six months ended June 30, 2025, was $265 million and $535 million, respectively, including $239 million and $485 million of accelerated depreciation, respectively. This depreciation was included within the “Depreciation and amortization” line item on our consolidated statement of income reported in our Refining segment. In the first quarter of 2026, we transferred $2,965 million in gross PP&E and $2,699 million of accumulated depreciation and amortization associated with the idled Los Angeles Refinery from our Refining segment to Corporate and Other.
