Why did MPC's earnings decline so significantly in Q4 2024?

The decline was driven primarily by lower market crack spreads, which compressed Refining & Marketing margins. R&M margin fell to $12.93 per barrel from $17.81, and segment adjusted EBITDA fell to $559 million from $2.25 billion. Q4 2023 results were also boosted by higher Other income and gains, so the year-over-year comparison is particularly weak.

What is the Renewable Diesel segment, and why was it created?

Beginning in Q4 2024, MPC reports renewable diesel activities separately from Refining & Marketing. The segment includes the wholly owned Dickinson, North Dakota facility (184 million gallons per year), the 50/50 Martinez Renewable Fuels joint venture with Neste (730 million gallons per year), and other assets. Management said the change improves comparability with peers that report refining and renewable diesel separately. Prior periods were recast. The segment posted positive Q4 adjusted EBITDA of $28 million but a full-year loss of $150 million.

What are the major growth projects announced with this release?

MPLX announced a Gulf Coast fractionation complex of two 150 thousand bpd facilities next to MPC's Galveston Bay refinery, expected in service in 2028 and 2029, with MPC contracting to purchase offtake. MPLX also announced a partnership with ONEOK to build a 400 thousand bpd LPG export terminal and pipeline, expected in service in 2028. The BANGL NGL pipeline expansion to 300 thousand bpd (second half of 2026) and the Blackcomb and Rio Bravo natural gas pipelines (second half of 2026) are also underway.

What does the Q1 2025 outlook suggest for refining operations?

MPC guided to Q1 2025 refining operating costs of $5.70 per barrel (excluding turnaround and D&A), distribution costs of $1.525 billion, planned turnaround costs of $450 million, and total refinery throughput of 2.77 million bpd. Investors should note that the refining operating cost guidance is higher than the Q4 2024 actual of $5.26 per barrel, and that turnaround costs are a meaningful quarterly swing factor.

MPC 8-K: Earnings & Results

Q: How much capital is MPC returning to shareholders, and can it keep doing so?

MPC returned $10.2 billion in 2024 and $1.6 billion in Q4 alone, including $1.3 billion of buybacks and $292 million of dividends. It has $7.8 billion of remaining repurchase authorization. Management expects 2025 MPLX distributions to cover MPC's dividends and its $1.25 billion standalone capital budget, which supports the capital return commitment. Sustainability depends on refining margins, since lower margins reduced 2024 cash generation, and the filing notes that buybacks and dividends are subject to free cash flow availability.

01—Abstract

Summary

Summary of the 8-K filed February 4, 2025. Cited figures are marked; the original filing is the authoritative source.

Marathon Petroleum reported sharply weaker fourth-quarter 2024 results, driven primarily by lower market crack spreads.

Net income attributable to MPC fell to $371 million^a, or $1.15 per diluted share, from $1.5 billion, or $3.84, a year earlier. Adjusted net income was $249 million, or $0.77 per diluted share, versus $3.98 in Q4 2023. Adjusted EBITDA dropped to $2.1 billion from $3.6 billion.

For full-year 2024, adjusted diluted EPS was $9.51^b and adjusted EBITDA was $11.3 billion, down from $19.1 billion in 2023. Refining & Marketing was the main drag, with segment adjusted EBITDA of $559 million in Q4 (about $2.03 per barrel) versus $2.2 billion a year earlier. Midstream was the bright spot, with segment adjusted EBITDA rising to $1.7 billion on higher rates, volumes, and recent Utica and Permian acquisitions.

MPC also reorganized its reporting by creating a Renewable Diesel segment, which carries prior-period recast figures and includes the Dickinson facility and the 50/50 Martinez Renewable Fuels joint venture with Neste. Renewable Diesel segment adjusted EBITDA turned positive in Q4 at $28 million^c, though full-year 2024 remained negative at $(150) million. Management emphasized capital return: MPC returned $10.2 billion to shareholders in 2024, including $1.6 billion in Q4, and had $7.8 billion remaining under share repurchase authorizations at year-end.

Year-end cash and equivalents were $3.2 billion^d, with $5 billion available on the revolving credit facility. Management expects MPLX distributions in 2025 to cover MPC's dividends and its $1.25 billion standalone capital budget.

Looking ahead, MPLX announced a Gulf Coast NGL strategy that includes a fractionation complex adjacent to the Galveston Bay refinery (in service 2028-2029) and a strategic partnership with ONEOK for a 400 thousand bpd LPG export terminal (2028). Investors should weigh the recovery in refining margins against heavy 2025 capital needs at MPLX ($2.0 billion) and the company's ongoing debt, which totaled $27.5 billion at year-end, mostly at MPLX.
