Detailed Narrative
Strategic Capital Deployment and Portfolio Optimization
MPLX deployed $5.5 billion in 2025, primarily focusing on natural gas and NGL value chains in high-growth regions like the Permian and Marcellus. The company's 2026 capital plan of $2.4 billion continues this strategy, with 90% of growth capital directed towards natural gas and NGL services, targeting mid-teens returns. This disciplined investment approach, coupled with divestitures of noncore assets, aims to build a more resilient and competitive platform for future energy needs.
Advancing Permian NGL Wellhead-to-Water Strategy
MPLX is integrating sour gas treating operations acquired last year into its Delaware Basin footprint, with the Titan treating complex construction progressing on time and budget to treat over 400 MMcf/d by end of 2026. The company announced Secretariat II, a new $320 million, 300 MMcf/d processing plant expected online in H2 2028, which will bring total Delaware Basin processing capacity to approximately 1.7 Bcf/d. This expansion supports both new and legacy volumes in the region.
Downstream Infrastructure and Export Capacity Expansion
The BANGL pipeline expansion is on schedule, with incremental capacity expected online in Q4 2026. MPLX is also advancing construction of 300,000 bbl/d of Gulf Coast fractionation capacity and a 400,000 bbl/d LPG export terminal JV, both expected online in 2028. These projects, benefiting from advantaged proximity to open water, are designed to serve growing global markets with greater efficiency and are underpinned by strong regulatory engagement.
Marcellus Basin Growth and Infrastructure Development
Construction is progressing on the 300 MMcf/d Harmon Creek III gas processing and fractionation complex in the Marcellus, with completion expected in Q3 2026. This will increase Northeast processing capacity to 8.1 Bcf/d and fractionation capacity to 800,000 bbl/d. Additionally, a $450 million Marcellus gathering system expansion, including compression and pipeline additions, is planned to enter service in H1 2028, targeting mid-teens returns and supporting producer needs.
Strong Financial Performance and Unitholder Returns
MPLX achieved a 6.7% 3-year adjusted EBITDA CAGR, enabling a 12.5% increase in its quarterly distribution for 2025, contributing to $4.4 billion in total unitholder returns. The company expects this level of distribution growth for two more years, while maintaining a strong balance sheet with distribution coverage above 1.3x and leverage below 4.0x. Growth in 2026 is projected to exceed 2025, with mid-single-digit EBITDA growth anticipated in 2027.
