Summary
Summary of the 8-K filed September 9, 2025. Cited figures are marked; the original filing is the authoritative source.
Phillips 66 (NYSE: PSX) announced on September 9, 2025 that its subsidiaries have signed a definitive agreement to acquire the remaining 50% equity interest in WRB Refining LP from subsidiaries of Cenovus Energy Inc. for $1.4 billiona in cash, subject to customary purchase price adjustments.
Phillips 66 already operates the joint venture, which owns the Wood River refinery in Roxana, Illinois and the Borger refinery in Borger, Texas, so the deal converts an operated 50/50 partnership into full ownership of both assets. Management expects roughly $50 millionb per year in operational and commercial synergies from fully integrating the refineries with Phillips 66's broader value chain, and sees potential for low-capital, high-return projects. The refineries have combined crude throughput capacity of about 345 MBD (Wood River) and 149 MBD (Borger), and the company states the deal would add roughly 250 MBD to its refining capacity at closing.
The transaction is expected to close in the fourth quarter of 2025. For investors, the key considerations are the $1.4 billionc cash outlay relative to the scale of the added capacity, the stated synergy target, and execution risk around closing and integration. The filing is a brief Item 8.01 disclosure that incorporates the press release by reference and does not include detailed financial statements, purchase accounting, or financing details, so those items should be sought in future filings.
