What the filing says
Marathon Petroleum reported Q2 2026 net income of $5.1 billion ($17.73/diluted share) vs. $1.2 billion in Q2 2025, with adjusted EBITDA of $8.5 billion vs. $3.3 billion YoY. The Refining & Marketing segment generated $6.7 billion EBITDA driven by higher crack spreads ($36.33/bbl margin vs. $17.58/bbl prior year). El Paso and Robinson yield-enhancing refinery investments were completed in Q2 2026; MPLX increased growth capex guidance by $500M to $2.9B for 2026, targeting Gulf Coast fractionation and Permian/Marcellus natural gas infrastructure. MPC returned $2.8B capital to shareholders and maintained $7.8B cash with no debt drawn on $5B revolver.
Why this rating
Strong earnings reflect favorable commodity environment, not structural business change. Refinery capex projects routine optimization; $500M MPLX increase is ~2% of enterprise value, supporting but not transforming growth trajectory.
