MPLX Q3 Adjusted EBITDA Rises 5% as Gas Projects Ramp

MPLX LP reported a 5% year-over-year increase in third-quarter adjusted EBITDA as higher rates, increased butane blending and growth across its natural gas and natural gas liquids operations offset the effect of assets divested in 2025. The midstream partnership also increased its quarterly distribution by 12.5% for the third consecutive year while advancing projects expected to add processing, treating and pipeline capacity.

Adjusted EBITDA attributable to MPLX rose to $1.86 billion from $1.77 billion a year earlier. Distributable cash flow attributable to limited partner unitholders increased to $1.54 billion from $1.47 billion, supporting $1.1 billion of distributions and $50 million of unit repurchases during the quarter.

GAAP net income declined to $1.17 billion from $1.56 billion. The year-earlier period included a $484 million gain on equity-method investments. Net cash provided by operating activities increased to $1.48 billion from $1.43 billion.

Adjusted free cash flow was $447 million, compared with negative $2.31 billion in the prior-year quarter. After distributions, adjusted free cash flow remained negative at $645 million, versus negative $3.28 billion a year earlier. Total growth and maintenance capital expenditures increased to $1.04 billion from $714 million.

Logistics and gas operations post higher adjusted EBITDA

Adjusted EBITDA from Crude Oil and Products Logistics increased 6% to $1.20 billion. MPLX attributed the improvement to higher rates across its business units and increased butane blending, partly offset by higher operating expenses, primarily compensation costs.

Crude-oil pipeline volumes rose 1% to 3.9 million barrels per day, while product pipeline volumes were unchanged at 2.1 million barrels per day. Terminal throughput increased 6% to 3.4 million barrels per day.

Natural Gas and NGL Services adjusted EBITDA increased 4% to $655 million. Growth, including contributions from acquisitions and equity affiliates, more than offset a $34 million reduction associated with the 2025 divestiture of non-core gathering and processing assets. Higher compensation expense also weighed on the segment.

Reported gathering volumes increased 4% to 7.2 billion cubic feet per day, processing volumes declined 1% to 9.9 Bcf/d, and fractionation volumes rose 3% to 696,000 barrels per day. Excluding divested assets, gathering, processing and fractionation volumes increased 14%, 5% and 4%, respectively.

Processing utilization reached 94% in the Marcellus and 89% in the Utica. MPLX said increasing producer activity was supporting higher utilization across the Marcellus, Utica and Permian regions.

Expansion projects support second-half growth plan

MPLX placed the Harmon Creek III complex into service and continued ramping throughput at Harmon Creek III and the Secretariat I gas-processing plant. Harmon Creek III adds 300 MMcf/d of processing capacity and a 40,000-barrel-per-day de-ethanizer in the Marcellus. Secretariat I adds 200 MMcf/d in the Permian, increasing the partnership’s processing capacity there to 1.4 Bcf/d.

The company is expanding the BANGL pipeline to 300,000 barrels per day, with service expected in the fourth quarter of 2026. It is also increasing Delaware Basin sour-gas treating capacity to more than 400 MMcf/d and connecting the system to area processing plants.

MPLX expects the Bay Runner pipeline, designed to supply about 2.6 Bcf/d of natural gas to LNG facilities in Brownsville, Texas, and the 2.5-Bcf/d Blackcomb pipeline to enter service in the fourth quarter. More than 90% of the partnership’s 2026 growth capital is being allocated to Natural Gas and NGL Services investments.

Management continues to target mid-single-digit growth for 2026, supported by integrated natural gas and NGL value chains, sour-gas treating investments and the company’s Marcellus footprint. Base distributions remain MPLX’s primary capital-return tool, with unit repurchases used opportunistically for incremental returns.

Total debt stood at $27.01 billion at the end of the quarter, up from $26.01 billion at the end of 2025. The ratio of total debt to last-12-month adjusted EBITDA was 3.8 times, compared with 3.7 times at year-end. MPLX issued $2.25 billion of senior notes in August and redeemed $1.25 billion of notes due in March 2027 during September.

The company cautioned that its outlook remains subject to construction costs and project schedules, regulatory approvals, commodity prices and hydrocarbon demand. Other uncertainties include access to debt markets, joint-venture funding and distribution decisions, geopolitical conflict, tariffs, inflation, interest rates, extreme weather and potential operational disruptions.
