MPLX Lifts 2026 Growth Capex to USD 2.9 Billion as Gas and NGL Earnings Offset 4% Pipeline Decline

MPLX LP raised its 2026 growth capital spending outlook by USD 500 million to USD 2.9 billion, citing accelerated execution of its Gulf Coast fractionation project to meet global demand for U.S. energy. The increase lands in a quarter where pipeline throughput fell 4% while gas processing earnings climbed.

Total pipeline throughput dropped to 5,876 mbpd in the second quarter of 2026 from 6,103 mbpd a year earlier. Natural Gas and NGL Services segment adjusted EBITDA rose to USD 614 million from USD 552 million, a gain of USD 62 million year on year. Crude Oil and Products Logistics adjusted EBITDA reached USD 1,161 million against USD 1,138 million, an increase of USD 23 million.

Adjusted EBITDA attributable to MPLX totalled USD 1,775 million, compared with USD 1,690 million in the second quarter of 2025. That is a 5% year-on-year advance to USD 1.8 billion, helped by stronger natural gas and NGL volumes and higher butane blending benefits, according to Investing.com. Net income attributable to MPLX was USD 1,077 million versus USD 1,048 million.

Gathering volumes rose 15% year on year, driven by growth in the Utica, Permian and Marcellus basins, chief financial officer Chris Hagedorn said. Marcellus processing ran at 96%, a record utilization level for the system, while the Delaware Basin processing network closed the quarter at 86%.

Revenue came in at USD 3.31 billion with earnings per unit of USD 1.06. Revenue beat forecasts by USD 140 million, or 4.42%, while EPS fell USD 0.01 short of expectations.

Cash generation held up against the higher spending plan. MPLX produced USD 1,702 million in net cash from operating activities, USD 1,450 million of distributable cash flow and USD 668 million of adjusted free cash flow. The partnership declared a second-quarter distribution of USD 1.0765 per common unit, giving distribution coverage of 1.3x, and paid out more than USD 1.1 billion to unitholders during the quarter, supporting a dividend yield of 7.31%.

The leverage ratio stood at 3.7x at quarter end, against 3.1x a year earlier. As of June 30, 2026, MPLX held USD 1.0 billion in cash, USD 2.5 billion available on its bank revolving credit facility and USD 1.5 billion available through its intercompany loan agreement with MPC.

Management expects distribution increases of 12.5% in both 2026 and 2027, per the release issued in Findlay, Ohio, on August 4, 2026, with the coverage target held at 1.3x. InvestingPro data show 14 consecutive years of payments and dividend growth of 12.6% over the trailing twelve months.

The build-out schedule explains where the additional capital goes. The wholly owned Harmon Creek III plant in the Marcellus, with 300 MMcf/d of gas processing capacity and a 40 mbpd de-ethanizer, begins operations in August 2026. Titan II is on track to expand sour gas treating capacity to more than 400 million cubic feet per day by year end, and BANGL is expected to reach 300,000 barrels per day in the fourth quarter.

For midstream investors outside North America, the segment split is the readable signal: liquids logistics throughput is contracting while processing and fractionation capacity is being added against export-linked demand. MPLX units last traded at USD 59.21, up 0.5% from the prior close of USD 58.91 and close to a 52-week high of USD 60.
