MPLX reported third-quarter 2026 net income attributable to MPLX of $1,164 million, down from $1,545 million a year earlier, while adjusted EBITDA rose 5.3% to $1,859 million. The partnership also raised its quarterly distribution 12.5% to $1.2111 per unit, the third straight annual increase, which matters to unitholders because cash returned to them is the main reason they hold the units.
