MPLX LP Q2 2026 Earnings Recap

MPLX’s shares rose modestly by 0.6% post-earnings, reflecting a quarter that delivered steady operational progress and a stable outlook, but without a clear catalyst to move the stock meaningfully higher.

Key Takeaways

• Adjusted EBITDA grew 5% year-over-year to $1.8 billion, overcoming the impact of the Rockies asset divestiture in late 2025.
• Processing utilization remained strong with 96% in Marcellus and 86% in the Delaware Basin; the new Harmon Creek III plant began operations in August, expanding processing capacity.
• Capital spending guidance was increased by $500 million to $2.9 billion, primarily due to accelerated Gulf Coast fractionation project execution.
• Mid-single-digit adjusted EBITDA growth is expected for 2026, weighted toward the back half, supported by multiple projects coming into service in the second half.
• Operational highlights included volume growth across gathering and processing segments, driven by production increases in Utica, Permian, and Marcellus basins, partially offset by the Rockies divestiture.
