Marathon Petroleum Corporation filed a Form S-3 shelf registration to offer various securities. The prospectus dated May 6, 2026 registers the potential, at‑the‑market issuance from time to time of senior and subordinated debt, common and preferred stock, warrants, stock purchase contracts and units, with specific terms to be provided in prospectus supplements.
The prospectus incorporates by reference MPC’s Form 10-K for year ended December 31, 2025 and Form 10-Q for quarter ended March 31, 2026, and discloses that MPC operates ~3.0 million barrels per day of crude oil refining capacity and owns the general partner and ~64% of MPLX common units as of December 31, 2025.
Marathon Petroleum reported much stronger Q1 2026 results, returning to profitability. Total revenues and other income rose to $34.6 billion from $31.9 billion a year earlier, helped by higher refining margins and stable product demand.
Net income attributable to MPC swung to $511 million, or $1.73 per diluted share, from a loss of $74 million, or $(0.24) per share, in Q1 2025. Segment adjusted EBITDA increased to $3.0 billion, led by Refining & Marketing, which saw EBITDA rise to $1.38 billion as global product prices improved despite derivative losses.
Operating cash flow improved sharply to $1.1 billion, compared with a small outflow in the prior-year quarter, while consolidated capital expenditures were $1.0 billion. MPC repurchased 4 million shares for $750 million at an average price of $213.45 and ended the quarter with $2.2 billion in cash and total debt of $33.3 billion. The board later approved an additional $5.0 billion share repurchase authorization.
Marathon Petroleum Corporation reported a strong turnaround in first-quarter 2026 results. Net income attributable to MPC was $511 million, or $1.73 per diluted share, compared with a net loss of $(74) million, or $(0.24) per diluted share a year earlier.
Adjusted net income was $487 million, or $1.65 per diluted share. Cash provided by operating activities reached $1.1 billion, versus $(64) million in the prior-year quarter. Adjusted EBITDA rose to $2.8 billion from $2.0 billion, driven mainly by a sharp improvement in the Refining & Marketing segment.
The company returned over $1.0 billion of capital to shareholders in the quarter and its board approved an incremental $5 billion share repurchase authorization, which would have brought total available repurchase capacity to $8.6 billion as of March 31, 2026.
