Summary
Summary of the 8-K filed May 5, 2026. Cited figures are marked; the original filing is the authoritative source.
Marathon Petroleum (MPC) reported first-quarter 2026 net income attributable to MPC of $511 milliona, or $1.73 per diluted share, compared with a net loss of $(74) million, or $(0.24) per share, a year earlier.
Adjusted net income was $487 millionb, or $1.65 per diluted share. The adjustment removes $32 million of pre-tax clean fuel production tax credits recognized for 2025 after February 2026 proposed guidance clarified 45Z qualification. Adjusted EBITDA rose to $2.76 billion from $1.98 billion, and operating cash flow swung to $1.1 billion from $(64) million.
The improvement was driven mainly by Refining & Marketing, where segment adjusted EBITDA reached $1.38 billionc, or $5.37 per barrel, versus $489 million, or $1.91 per barrel, on higher crack spreads. Midstream adjusted EBITDA declined to $1.60 billion from $1.72 billion, mainly because of $77 million of derivative losses on economic hedges. The company remains in a heavy investment phase.
Q1 capital expenditures were $1.25 billiond, up from $776 million, with Midstream spending of $892 million, and 2026 MPC capital spending (excluding MPLX) is guided to $1.5 billion. Refining planned turnaround costs were $530 million, and about 40% of 2026 planned turnaround activity was completed in the quarter. Management highlighted the Garyville jet flexibility project as online, with El Paso FCC and Robinson jet projects targeted for 2Q26 and 3Q26.
MPLX's growth plan is expected to support 12.5% annual distribution growth to MPC in 2026 and 2027. Capital return is a central theme. MPC returned over $1.0 billion in the quarter and the Board approved an incremental $5 billion share repurchase authorization, which would bring available authorization to $8.6 billion as of March 31, 2026.
Balance sheet metrics are solid: MPC had $2.2 billion of cash (including $1.5 billion at MPLX) and no borrowings under its $5 billion revolver, though total consolidated debt was $32.8 billion, with $25.6 billion at MPLX. Shares outstanding fell to 293 million from 295 million at year-end, and equity declined to $23.4 billion from $24.1 billion. Investors should note that the Item 2.02 disclosure is furnished rather than filed, and that the results are heavily influenced by refining margin volatility and hedging.
02—Key points
Key Highlights
- Net income attributable to MPC was $511 million ($1.73 per diluted share) versus a $(74) million loss ($(0.24)) in Q1 2025; adjusted EPS was $1.65 after excluding $32 million of pre-tax 2025 clean fuel production tax credits.
- Adjusted EBITDA increased to $2.76 billion from $1.98 billion, and operating cash flow was $1.1 billion versus $(64) million a year earlier.
- Refining & Marketing adjusted EBITDA rose to $1.38 billion ($5.37/bbl) from $489 million ($1.91/bbl), with R&M margin of $17.74/bbl versus $13.38/bbl; West Coast and Gulf Coast led the improvement.
- Midstream adjusted EBITDA fell to $1.60 billion from $1.72 billion, reflecting $77 million of economic hedge derivative losses and the absence of a $37 million non-recurring benefit from the prior year.

03—Questions
Frequently Asked Questions
Why is adjusted EPS ($1.65) lower than reported EPS ($1.73)?
Management excluded $32 million of pre-tax clean fuel production tax credits (about $24 million after an $8 million tax effect). These credits relate to 2025 and were recognized in Q1 2026 after proposed regulatory guidance issued in February 2026 clarified 45Z qualification criteria. Excluding them presents results closer to the quarter's underlying operating performance.
What drove the improvement in refining profitability?
Higher crack spreads were the primary driver, with R&M margin reaching $17.74/bbl versus $13.38/bbl. Q1 crude utilization was 89% and throughput was 2.9 million bpd. Partially offsetting this were derivative losses under the economic hedging program and higher refining operating costs ($6.23/bbl versus $5.74/bbl), largely from increased turnaround-related project expense.
How much buyback capacity does MPC now have, and is the balance sheet strong enough to support it?
Following the new $5 billion authorization, MPC would have had $8.6 billion available as of March 31, 2026, versus $3.6 billion before it. MPC-level debt was $7.2 billion, with no revolver borrowings and $2.2 billion of consolidated cash. Consolidated debt of $32.8 billion is concentrated at MPLX ($25.6 billion), so investors should weigh MPC's standalone leverage separately from MPLX's obligations. Repurchase pace will depend on market conditions and may be suspended at any time.
What is the outlook for MPLX growth and its contribution to MPC?
MPLX has a $2.4 billion organic growth capital plan, with 90% directed at natural gas and NGL infrastructure in the Permian and Marcellus. Key in-service dates include Harmon Creek III (3Q26), Bay Runner (3Q26), Titan Complex and BANGL expansion (4Q26), and Blackcomb (4Q26). Management expects these projects to support 12.5% annual distribution growth to MPC in 2026 and 2027 and to generate mid-teens returns. Midstream earnings may remain pressured in the near term by hedging losses, as seen in Q1.
