MPLX LP is a Public Limited Company registered in United States under 811014980, and its current status with Ohio Secretary of State is active. The company was incorporated on 25 April 2012 and lists its registered address as Findlay, United States. 5 shareholders are on record for MPLX LP, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Ohio Secretary of State and was last updated on 6 October 2026.

Shareholders

5

Five shareholders are currently on record for MPLX LP, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.

The largest of these is ALPS ETF TRUST-ALERIAN MLP ETF, holding 13.6% — the largest recorded stake — followed by AIM Investment Fd.s -Invesco SteelPath MLP Income Fd. at 6%; the remaining 3 shareholders shown hold smaller stakes.

The register reports 6 shareholders in total, though only the top 5 by holding are shown in this view.

Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Group Structure

MPLX LP sits 1 level below its ultimate parent, Marathon Petroleum Corporation, registered in United States. 62 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Marathon Petroleum Corporation is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by MPLX LP's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.

Those 62 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 62 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
