Future Outlook

Global demand growth for refined products is expected to outpace net refining capacity additions and rationalizations through the end of the decade, supporting a constructive environment for U.S. refiners. The Midstream business is well positioned with significant opportunities to support producer development plans, focusing on expanding its Permian to Gulf Coast integrated value chain, progressing long-haul pipeline growth projects, and investing in new gas processing plants. MPC's 2026 capital investment outlook is approximately $1.5 billion, with a focus on high-return investments in refining and marketing. MPLX's 2026 capital investment outlook is $2.7 billion, primarily for growth capital. Environmental capital expenditures are expected to be $183 million in 2026. The company intends to maintain an investment-grade credit profile for both MPC and MPLX. The EPA has proposed increasing annual renewable fuel volumes for 2026 and 2027, and the Army Corps has recommended continued operation of the Dakota Access Pipeline.
