Summary

Summary of the 10-Q filed May 5, 2026. Cited figures are marked; the original filing is the authoritative source.

MPLX LP reported solid financial results for the first quarter of 2026, with Net income attributable to MPLX LP of $912 milliona, a decrease from $1,126 million in the prior year period.

This decrease was primarily driven by a $214 millionb decline in net income, largely attributable to increased costs and expenses, including higher purchased product costs and depreciation, as well as increased net interest and other financial costs due to higher borrowings. Total revenues and other income saw a slight decrease of $86 million year-over-year, impacted by lower product-related revenue and the divestiture of Rockies operations, though partially offset by increased rental and service revenues. Despite the year-over-year decline in net income, the company demonstrated strong operational cash flow, generating $1.35 billion in net cash from operating activities.

Management highlighted robust Adjusted EBITDA of $1.73 billionc and Distributable Cash Flow (DCF) of $1.41 billion, enabling the return of $1.09 billion in capital to unitholders through distributions and unit repurchases. The company also announced a first-quarter 2026 distribution of $1.0765 per common unit. MPLX continues to execute its strategic priorities, including investments in growth projects and maintaining its commitment to returning capital to unitholders.
