Question · Q3 2025
Paul Cheng asked about the quantitative impact of inventory build on Marathon Petroleum's Q3 margin capture, seeking a dollar per barrel or percentage figure. He also questioned MPC's strategy regarding new pipeline proposals in California and whether the company plans to be an active and aggressive importer of refined products into the California market.
Answer
CFO John Quaid estimated the inventory build's impact on capture to be closer to 3-5%, driven by LPGs for blending and VGO ahead of FCC turnarounds. CCO Rick Hessling stated that a potential MidCon pipeline into California would be bullish for MPC due to their MidCon assets, but noted significant 'ifs' regarding its realization. He indicated that while MPC would evaluate waterborne trading opportunities, it would not be a primary focus, emphasizing optimizing their integrated West Coast and Pacific Northwest value chain.
