About MPLX LP
About MPLX LP
MPLX LP owns and operates 14,853 miles of crude oil, refined product, and natural gas pipelines, 88 terminals, 9.4 billion cubic feet per day of gas gathering capacity, and 819 mbpd of fractionation and de-ethanization capacity across the United States. Two reportable segments — Crude Oil and Products Logistics, and Natural Gas and NGL Services — served markets across the Gulf Coast, Mid-Continent, and West Coast in 2025. In that year, MPC accounted for 48% of MPLX's total revenues, with approximately 88% of Crude Oil and Products Logistics segment revenues derived from MPC.
MPLX earns revenue through two distinct streams. In Crude Oil and Products Logistics, the partnership charges tariffs for transporting crude oil and refined products across its pipeline network, collects per-barrel storage fees at terminals and caverns, and provides fuels distribution scheduling services to MPC at tiered monthly fees, most under long-term contracts with minimum volume commitments and deficiency payment provisions. Under the marine transportation agreement, MPC is committed to pay a fixed fee for 100% of available boat and barge capacity. In Natural Gas and NGL Services, MPLX gathers, treats, processes, and fractionates gas and NGLs for producer customers across the Marcellus, Permian, Utica, STACK, and Bakken shale plays, with a revenue mix across fee-based, percent-of-proceeds, and keep-whole contract types. One Southwest region NGL customer represented approximately 20% of Natural Gas and NGL Services segment revenues in 2025.
Show full overview
MPLX's minimum volume commitments and deficiency payment structure provide revenue floor protection in the Crude Oil and Products Logistics segment, but credit exposure is concentrated in MPC: the 10-K explicitly names MPC materially suspending or terminating its obligations as a risk that, if realized, could cause the Crude Oil and Products Logistics segment — where MPC represented approximately 88% of 2025 segment revenues — to face severe throughput loss. The U.S. inland waterway system, on which MPLX's marine transportation business depends, presents an aging infrastructure risk: more than half of the system's locks exceed 50 years old, and planned or unplanned maintenance may increase operational disruptions and costs.
