MPLX leaned into its “wellhead to water” strategy and infrastructure development execution as the core narratives of its Q4 2025 earnings call. Management reiterated its 2026 capital plan of roughly $2.4 billion. President and CEO, Maryann Mannen, stated “90% of our growth capital will be directed towards our natural gas and NGL services segment, where we see some of the most compelling opportunities in the midstream sector.” Projects including Secretariat II gas processing plant in the Permian, Harmon Creek III gas processing plant in the Marcellus, sour gas treating capacity expansion at the Titan facility in Eddy County, NM and Gulf Coast fractionation/LPG export build-outs were highlighted as key catalysts to lift throughput and fee-based earnings going forward.
