Net income attributable to MPC decreased by $299 million in Q2 2025 ($1,216M) compared to Q2 2024 ($1,515M), and by $1.31 billion for H1 2025 ($1,142M) versus H1 2024 ($2,452M). This led to a substantial drop in diluted EPS from $4.33 to $3.96 for Q2 and from $6.88 to $3.68 for H1.
Net cash provided by operating activities for the first six months of 2025 was $2,575 million, representing a significant decrease of $2.20 billion compared to $4,774 million in the same period of 2024. This decline was primarily attributed to lower operating results and an unfavorable change in working capital of $1.19 billion.
Total debt increased to $29,014 million at June 30, 2025, from $27,797 million at December 31, 2024. This rise reflects new senior note issuances by both MPC and MPLX, even as some maturing debt was repaid, indicating a net increase in leverage.
MPLX completed the Whiptail Midstream acquisition for $237 million in March 2025 and entered a definitive agreement to acquire Northwind Midstream for $2.375 billion in July 2025. These acquisitions significantly expand its crude oil and natural gas gathering and processing operations in key basins.
The Renewable Diesel segment reduced its adjusted EBITDA loss to $(19) million in Q2 2025 from $(27) million in Q2 2024, an $8 million improvement. This was driven by a $49 million increase in margin due to higher environmental credits and increased production volumes, which rose to 1,122 thousand gallons per day in Q2 2025 from 905 in Q2 2024.
Total capital expenditures and investments for MPC (excluding MPLX) rose to $738 million in H1 2025 from $616 million in H1 2024, and MPLX's capital investments significantly increased to $1,065 million from $565 million. This reflects a strong focus on strategic projects to enhance capacity and operational capabilities.
The Refining & Marketing segment adjusted EBITDA decreased by $132 million in Q2 2025 compared to Q2 2024. This was primarily due to an estimated net negative impact of $500 million on margins from narrower crude oil differentials and lower crack spreads.
MPC issued $2.0 billion in senior notes in February 2025 to refinance $2.0 billion of maturing debt, and MPLX issued $2.0 billion in senior notes in March 2025 to redeem $1.2 billion of its maturing debt. This demonstrates management's active approach to managing debt maturities and maintaining financial flexibility.
MPC sold its 49.9% interest in The Andersons Marathon Holdings LLC (TAMH) for $425 million in July 2025, expecting to recognize an estimated gain of $245 million in Q3 2025. This move signals management's focus on optimizing its asset portfolio and generating non-recurring gains.
MPC is subject to multiple climate-related lawsuits in various states, alleging misrepresentation regarding petroleum product impacts and seeking unspecified damages. The ultimate outcome and potential liability for these proceedings remain uncertain, representing an ongoing legal and financial risk.
The 'One Big Beautiful Bill Act,' enacted in July 2025 with provisions effective in 2025, includes changes to bonus depreciation and international tax frameworks. MPC is currently assessing the impact of this new legislation on its consolidated financial statements, introducing a new layer of regulatory uncertainty.
The Refining & Marketing segment experienced a net negative impact of approximately $500 million on its margin in Q2 2025 compared to Q2 2024. This was primarily due to narrower sour and sweet crude oil differentials and lower crack spreads, highlighting the ongoing exposure to volatile market conditions.
While net refinery throughput remained stable at 3,060 mbpd in Q2 2025 (vs 3,051 mbpd in Q2 2024), the segment's adjusted EBITDA per barrel declined to $6.79 from $7.28. This indicates reduced profitability per unit of output amidst market pressures, suggesting a challenging competitive environment for refining margins.
The Midstream segment reported a $21 million increase in adjusted EBITDA for Q2 2025, driven by higher pipeline throughput (6,219 mbpd vs 6,129 mbpd) and natural gas processed volumes (9,740 MMcf/d vs 9,568 MMcf/d). This performance reflects a robust operational position and ability to capture market opportunities.
Renewable Diesel sales volume increased to 1,307 thousand gallons per day in Q2 2025 from 1,102 thousand gallons per day in Q2 2024, with produced volume also rising to 1,122 thousand gallons per day from 905 thousand gallons per day. This growth indicates increasing market penetration and operational scaling in the renewable fuels sector.
Refining operating costs per barrel rose to $5.34 in Q2 2025 from $4.91 in Q2 2024, primarily due to a $123 million increase in total energy costs. This indicates pressure on operational efficiency within the Refining & Marketing segment from rising input costs.
Depreciation and amortization decreased by $49 million in Q2 2025 compared to Q2 2024, largely due to major refining assets becoming fully depreciated at the end of 2024. This reduction positively impacts net income and reflects a more mature asset base.
Expenses associated with purchased Renewable Identification Numbers (RINs) increased to $314 million in Q2 2025 from $293 million in Q2 2024. This increase was mainly due to higher obligated volumes and average RIN prices, adding to the cost structure and impacting the profitability of the Refining & Marketing segment.
