Phillips 66 has agreed to acquire the remaining 50% stake in WRB Refining from Cenovus Energy for $1.4 billion, a strategic move to bolster its refining capacity and integrated energy operations. This transaction grants Phillips 66 full ownership of two key U.S. refineries, strategically enhancing its footprint in the North American energy landscape and solidifying operational control over these vital assets.
The acquisition specifically encompasses the Wood River refinery in Illinois and the Borger refinery in Texas. These facilities collectively boast a substantial crude throughput capacity of 495,000 barrels per day (bbls/d), positioning them as critical components within Phillips 66’s expanded portfolio. Full ownership is expected to unlock further operational efficiencies and strategic advantages.
Phillips 66 CEO Mark Lashier underscored the strategic rationale, emphasizing that the full acquisition will strengthen the company’s integrated business model and expand its market leadership in the region. This move aligns with a broader strategy to optimize operational control and leverage synergies across its refining and midstream assets, crucial for navigating a dynamic energy market.
For Cenovus Energy, the divestment is projected to yield $1.4 billion in proceeds. The Canadian energy producer plans to allocate these funds towards reducing its net debt and accelerating returns to shareholders through increased share repurchases, reflecting a focused approach on capital efficiency and financial stewardship within its core operations.
The transaction is anticipated to conclude around the end of the third quarter. This consolidation of ownership comes as refining margins and energy demand navigate dynamic global market conditions, making strategic asset control and optimization pivotal for long-term stability and profitability in the sector.
