MPLX grew Q2 FY2026 total revenue 10% YoY to $3.31B, led by a 19% jump in Natural Gas and NGL Services on higher Southwest NGL volumes and prices, while operating margin slipped as purchased product costs and interest expense rose faster than revenue.

Watch Items from the Filing

MPC-related transactions accounted for 50% of total revenues and other income and 25% of total costs and expenses in Q2 2026, reflecting MPLX's continued dependence on its sponsor and largest customer.
Adjusted FCF after distributions was $(424)M for the quarter and $(968)M year-to-date, as growth capex and unitholder distributions outpaced operating cash flow.
MPLX raised its 2026 growth capital outlook by $500 million to $2.9 billion to accelerate Gulf Coast fractionation and export facility expansion for global NGL demand.
MPLX holds a 9.19% indirect interest in Dakota Access Pipeline; the Army Corps issued a Record of Decision in May 2026, but new litigation may follow the final EIS, with contingent equity exposure of approximately $78 million.
