Summary
Summary of the 8-K filed August 5, 2025. Cited figures are marked; the original filing is the authoritative source.
Marathon Petroleum (MPC) reported second-quarter 2025 net income attributable to MPC of $1.2 billiona, or $3.96 per diluted share, down from $1.5 billion, or $4.33 per diluted share, in the year-earlier quarter.
Adjusted EBITDA was $3.3 billionb versus $3.4 billion a year ago. Refining & Marketing segment adjusted EBITDA fell to $1.9 billion from $2.0 billion, with segment EBITDA per barrel at $6.79 versus $7.28, although refining utilization was strong at 97% and margin capture reached 105%. Midstream was flat at $1.6 billion, supported by higher rates and throughput that offset higher operating costs.
Capital allocation and portfolio moves were the main strategic story. MPC returned about $1.0 billionc to shareholders in the quarter, including $692 million of buybacks, and ended the period with $6.0 billion of repurchase authorization remaining. Its balance sheet deleveraged: MPC-level debt fell to $7.4 billion from $8.5 billion after repaying $1.25 billion of senior notes, and the company had no revolver borrowings.
MPLX separately agreed to acquire Northwind Midstream for $2.375 billiond in cash, expected to close in Q3 2025 subject to regulatory clearance, and MPC is selling its ethanol joint venture stake for $425 million gross. Looking ahead, the Q3 2025 outlook calls for refinery throughput of 2.94 million bpd, refining operating costs of $5.70 per barrel, and planned turnaround costs of $400 million.
Management is also funding several refinery and midstream growth projects, including the Galveston Bay distillate hydrotreater and Permian gas processing and pipeline expansions. Investors will want to watch refining margin conditions, the execution and financing of the Northwind deal and related MPLX debt, and the pace of buybacks.

03—Questions
Frequently Asked Questions
Why did MPC's earnings decline year over year in Q2 2025?
Net income attributable to MPC fell to $1.2 billion ($3.96 per diluted share) from $1.5 billion ($4.33) in Q2 2024. The main drivers were a weaker R&M margin per barrel environment, higher refining operating costs ($5.34/bbl vs. $4.91/bbl), higher net interest and other financial costs ($319 million vs. $194 million), and a $151 million gain on asset sales in the prior-year quarter that did not recur. Share count reduction from buybacks partly offset the decline in total earnings on a per-share basis.
How strong is MPC's balance sheet after the recent debt repayment?
MPC-level debt declined to $7.4 billion at June 30, 2025, from $8.5 billion at March 31, 2025, after repaying $1.25 billion of notes in May. MPC had $1.7 billion of cash, including $1.4 billion at MPLX, and no borrowings on its $5 billion revolver, though it had $210 million of commercial paper outstanding. Total consolidated debt was $28.7 billion, mostly at MPLX ($21.2 billion), which is expected to take on additional debt to fund its acquisitions.
What does the Northwind Midstream acquisition mean for MPLX and MPC?
MPLX agreed to acquire Northwind Midstream's Lea County, New Mexico sour gas gathering and treating system for $2.375 billion in cash. The system has over 200,000 dedicated acres, 200+ miles of gathering pipeline, and is designed for 440 MMcf/d of sour gas treating capacity, expected to be fully online in 2H 2026 and supported by minimum volume commitments from top Delaware basin producers. The deal is expected to close in Q3 2025, subject to regulatory clearance, and MPLX plans to finance it with debt.
How is MPC returning capital to shareholders?
MPC returned approximately $1.0 billion in Q2 2025, including $692 million of share repurchases, and had $6.0 billion remaining under its repurchase authorizations at quarter-end. Shares outstanding fell to 304 million from 309 million over the quarter. Management frames the portfolio optimization, including the ethanol JV sale for $425 million, as supporting industry-leading capital returns.
What should investors expect from MPC's operations and capital spending in the second half of 2025?
For Q3 2025, MPC guided to crude refined volumes of 2.73 million bpd, total refinery throughput of 2.94 million bpd, refining operating costs of $5.70/bbl (excluding turnarounds and D&A), and planned turnaround costs of $400 million. Refining capital includes $100 million at Los Angeles, $150 million at Robinson, and $200 million at Galveston Bay in 2025, with the Galveston Bay hydrotreater completing by year-end 2027. Corporate expenses are expected at $240 million for the quarter.
