Will ExxonMobil's 100,000-BPD Diesel Expansion Boost Refining Profit?
ExxonMobil (XOM) plans to expand diesel production by 100,000 BPD, allocating $10B from its $100B 2027-2030 capital program. The move aims to improve earnings and cash flow, with investments in U.S. refineries like Beaumont and Baytown. Valero (VLO) and Marathon Petroleum (MPC) are also investing in refining efficiency. XOM's shares have risen 56% year-over-year, with a trailing 12-month EV/EBITDA of 8.59X.
