Bull points
- MPLX delivered over $1.7 billion of adjusted EBITDA, which enabled the return of over $1.1 billion to our unit holders.
- 2026 is the year of execution, with multiple investments expected to transition from construction to operations and EBITDA generation, with Secretariat I coming online in April, Harmon Creek III in the third quarter, and the Titan gas treating complex reaching over 400 million cubic feet per day of treating capacity in the fourth quarter.
- We see strategic opportunity to support increasing demand for these commodities.
Bear points
- Pipeline volumes decreased 4% year-over-year, primarily due to marathons, refining turnaround, and maintenance activities in the Midwest and Gulf Coast regions
- segment-adjusted EBITDA decreased $42 million compared to the first quarter of 2025
- Total fractionation volumes decreased 3% year-over-year, primarily due to lower ethane recovery in the Marcellus as a result of elevated regional gas prices in the first quarter
