•$2.0 billion of adjusted EBITDA, supported by the strength of the Midstream business

•Executing Natural Gas & NGL growth strategy with MPLX’s agreement to acquire 100% ownership in BANGL, LLC and FID of the Traverse natural gas pipeline

•$1.3 billion of capital returned, inclusive of $1.1 billion of share repurchases

FINDLAY, Ohio, May 6, 2025 – Marathon Petroleum Corp. (NYSE: MPC) today reported net loss attributable to MPC of $(74) million, or $(0.24) per diluted share, for the first quarter of 2025, compared with net income attributable to MPC of $937 million, or $2.58 per diluted share, for the first quarter of 2024.

The first quarter of 2025 adjusted earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA) was $2.0 billion, compared with $3.3 billion for the first quarter of 2024. Adjustments are shown in the accompanying release tables.

“Our first quarter results reflect the safe and successful execution of the second largest planned maintenance quarter in our company’s history and strong commercial performance,” said President and Chief Executive Officer Maryann Mannen. “Our Midstream business delivered an 8% increase in segment adjusted EBITDA over the prior year, and executed on our Natural Gas and NGL growth strategies. For our refining business, we are positioned to meet summer demand as seasonal trends are expected to improve margins and we remain constructive on its long-term outlook. We believe we are positioned over time to deliver peer-leading capital returns.”

Refining & Marketing (R&M)

Segment adjusted EBITDA was $489 million in the first quarter of 2025, versus $2.0 billion for the first quarter of 2024. R&M segment adjusted EBITDA was $1.91 per barrel for the first quarter of 2025, versus $8.22 per barrel for the first quarter of 2024. Segment adjusted EBITDA excludes refining planned turnaround costs, which totaled $454 million in the first quarter of 2025 and $647 million in the first quarter of 2024. The decrease in segment adjusted EBITDA was driven primarily by lower market crack spreads.

R&M margin was $13.38 per barrel for the first quarter of 2025, versus $19.35 per barrel for the first quarter of 2024. Crude capacity utilization was 89%, resulting in total throughput of 2.8 million barrels per day (bpd) for the first quarter of 2025.

Refining operating costs were $5.74 per barrel for the first quarter of 2025, versus $6.06 per barrel for the first quarter of 2024.

Midstream

Segment adjusted EBITDA was $1.7 billion in the first quarter of 2025, versus $1.6 billion for the first quarter of 2024. The results were primarily driven by higher throughputs and growth from equity affiliates.

Renewable Diesel

Segment adjusted EBITDA was $(42) million in the first quarter of 2025, versus $(90) million for the first quarter of 2024. The improvement in segment results was primarily due to increased utilization, particularly at our Martinez Renewables facility, and higher margins.

Corporate and Items Not Allocated

Corporate expenses totaled $210 million in the first quarter of 2025, compared with $228 million in the first quarter of 2024.

Financial Position, Liquidity, and Return of Capital

As of March 31, 2025, MPC had $3.8 billion of cash and cash equivalents, including $2.5 billion of cash at MPLX, and $5 billion available on its bank revolving credit facility.

On February 10, 2025, the company issued $2.0 billion in aggregate principal amount of unsecured senior notes. The senior notes offering was intended to replace the $750 million of senior notes that matured in September 2024 and refinance the $1.25 billion of senior notes that matured on May 1, 2025.

In the first quarter, the company returned approximately $1.3 billion of capital to shareholders. As of March 31, 2025, the company has $6.7 billion available under its share repurchase authorizations.

Strategic Update

MPC’s Refining & Marketing 2025 capital spending outlook includes continued high-return investments at its Los Angeles, Galveston Bay and Robinson refineries. In addition to these multi-year investments, the company is executing shorter-term projects that offer high returns through margin enhancement and cost reduction.

•Los Angeles: An investment targeted at improving the refinery’s competitiveness by integrating and modernizing utility systems to improve reliability and increase energy efficiency. It is also intended to address a regulation mandating emissions reductions for all Southern California refineries. Capital spend in 2025 is expected to be $100 million with completion targeted for year-end 2025.

•Robinson: A project that will increase the refinery’s flexibility to optimize jet fuel production to meet growing demand. Capital spend in 2025 is expected to be $150 million, with another $50 million in 2026. The project’s estimated completion is by year-end 2026.

•Galveston Bay: A 90 thousand barrel per day high-pressure distillate hydrotreater (DHT) that will upgrade high-sulfur distillate to higher-value ultra-low sulfur diesel. Capital spend in 2025 is expected to be $200 million, with another $575 million in 2026 and 2027. Completion of the DHT is expected by year-end 2027.

MPC’s Midstream segment is expanding its Permian to Gulf Coast integrated value chain, progressing long-haul pipeline growth projects to support expected increased producer activity, and investing in Permian and Marcellus processing capacity in response to producer demand. Updates include:

Newly Announced

•BANGL Pipeline: MPLX announced the strategic acquisition of the remaining 55% of BANGL, LLC for $715 million, resulting in 100% ownership. The system transports natural gas liquids from the Permian basin to markets along the Gulf Coast, and will connect to MPLX's announced Gulf Coast fractionation facilities. The transaction is expected to close in July, subject to customary closing conditions.

•Traverse Pipeline: MPLX and its partners announced FID of the Traverse Pipeline, a bi-directional pipeline designed to transport 1.75 billion cubic feet per day (bcf/d) of natural gas along the Gulf Coast between Agua Dulce and the Katy area. The pipeline enhances optionality for shippers to access multiple premium markets, and is expected in service in 2027.

•Matterhorn Express Pipeline: MPLX has entered into an agreement to increase its stake in the joint venture that owns and operates the Matterhorn Express pipeline by 5% for $151 million, bringing MPLX’s total interest in the pipeline to 10%. The pipeline is designed to transport up to 2.5 bcf/d of natural gas from the Permian basin to the Katy area near Houston. The transaction is expected to close in second quarter of 2025, subject to the satisfaction of closing conditions.

•Crude Gathering: MPLX expanded its crude oil value chain by acquiring gathering businesses from Whiptail Midstream, LLC for $237 million. These San Juan basin assets consist primarily of crude and natural gas gathering systems in the Four Corners region, and enhance supply to MPC’s refining systems.

Ongoing

•Gulf Coast Fractionators: Two 150 thousand barrel per day fractionation facilities near MPC’s Galveston Bay refinery. The fractionation facilities are expected in service in 2028 and 2029. MPC is contracting with MPLX to purchase offtake from the fractionators, which MPC intends to market globally.

•LPG Export Terminal: A strategic partnership with ONEOK, Inc. to develop a 400 thousand bpd LPG export terminal and an associated pipeline, which is anticipated in service in 2028.

•BANGL Pipeline: Expanding from 250 thousand bpd to 300 thousand bpd, which is anticipated to come online in the second half of 2026. This pipeline will enable liquids to reach MPLX's Gulf Coast fractionators.

•Blackcomb and Rio Bravo Pipelines: Progressing with an expected in-service date in the second half of 2026. These pipelines are designed to transport natural gas from the Permian to domestic and export markets along the Gulf Coast.

•Secretariat: A 200 million cubic feet per day (mmcf/d) processing plant is expected online in the fourth quarter of 2025, increasing MPLX's gas processing capacity in the Permian basin to 1.4 bcf/d.

•Harmon Creek III: A 300 mmcf/d processing plant and 40 thousand bpd de-ethanizer, expected online in the second half of 2026. This complex will increase MPLX's processing capacity in the Northeast to 8.1 bcf/d and fractionation capacity to 800 thousand bpd.

Non-GAAP Financial Measures

Management uses certain financial measures to evaluate our operating performance that are calculated and presented on the basis of methodologies other than in accordance with GAAP. The non-GAAP financial measures we use are as follows:

Adjusted EBITDA

Amounts included in net income (loss) attributable to MPC and excluded from adjusted EBITDA include (i) net interest and other financial costs; (ii) provision/benefit for income taxes; (iii) noncontrolling interests; (iv) depreciation and amortization; (v) refining planned turnaround costs and (vi) other adjustments as deemed necessary, as shown in the table below. We believe excluding turnaround costs from this metric is useful for comparability to other companies as certain of our competitors defer these costs and amortize them between turnarounds.

Adjusted EBITDA is a financial performance measure used by management, industry analysts, investors, lenders, and rating agencies to assess the financial performance and operating results of our ongoing business operations. Additionally, we believe adjusted EBITDA provides useful information to investors for trending, analyzing and benchmarking our operating results from period to period as compared to other companies that may have different financing and capital structures. Adjusted EBITDA should not be considered as a substitute for, or superior to income (loss) from operations, net income attributable to MPC, income before income taxes, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

Refining & Marketing Margin

Refining & Marketing margin is defined as sales revenue less cost of refinery inputs and purchased products. We use and believe our investors use this non-GAAP financial measure to evaluate our Refining & Marketing segment’s operating and financial performance as it is the most comparable measure to the industry’s market reference product margins. This measure should not be considered a substitute for, or superior to, Refining & Marketing gross margin or other measures of financial performance prepared in accordance with GAAP, and our calculation thereof may not be comparable to similarly titled measures reported by other companies.

Renewable Diesel Margin

Renewable Diesel margin is defined as sales revenue plus value attributable to qualifying regulatory credits earned during the period less cost of renewable inputs and purchased product costs. We use and believe our investors use this non-GAAP financial measure to evaluate our Renewable Diesel segment’s operating and financial performance. This measure should not be considered a substitute for, or superior to, Renewable Diesel gross margin or other measures of financial performance prepared in accordance with GAAP, and our calculation thereof may not be comparable to similarly titled measures reported by other companies.
