Refining Acquisition

On October 1, 2025, we acquired the remaining 50% equity interest in WRB Refining LP (WRB) from subsidiaries of Cenovus Energy Inc. (Cenovus) for total cash consideration of $1.3 billion. This acquisition enables full integration with our broader value chain and expands our position in the Central Corridor region.

The components of the fair value of the WRB acquisition consideration are:

Cash paid to Cenovus$1,340 
Fair value of previously held equity interest in WRB1,304

Total acquisition consideration$3,437 

The acquisition date fair value of the previously held equity interest in WRB was determined using a market approach and the valuation resulted in a Level 3 nonrecurring fair value measurement.
