Marathon Petroleum (MPC) Q1 2026 Earnings

Refining & Marketing (R&M)

Segment adjusted EBITDA was $1.4 billion in the first quarter of 2026, versus $489 million for the first quarter of 2025. R&M segment adjusted EBITDA was $5.37 per barrel for the first quarter of 2026, versus $1.91 per barrel for the first quarter of 2025. Segment adjusted EBITDA excludes refining planned turnaround costs, which totaled $530 million in the first quarter of 2026 and $454 million in the first quarter of 2025.

R&M margin was $17.74 per barrel for the first quarter of 2026, versus $13.38 per barrel for the first quarter of 2025. Crude capacity utilization was 89%, resulting in total throughput of 2.9 million barrels per day (bpd) for the first quarter of 2026. Results benefited from higher crack spreads, partially offset by derivative losses related to our economic hedging program.

Refining operating costs were $6.23 per barrel for the first quarter of 2026, versus $5.74 per barrel for the first quarter of 2025, reflecting higher project-related expense associated with increased turnaround activity. Full-year planned turnaround expense is unchanged, estimated at $1.35 billion.

Midstream

Segment adjusted EBITDA was $1.6 billion in the first quarter of 2026, versus $1.7 billion for the first quarter of 2025. The decrease was primarily driven by derivative losses of $77 million on economic hedges in the first quarter of 2026 and a $37 million non-recurring benefit associated with a customer agreement in the first quarter of 2025.

Renewable Diesel

Segment adjusted EBITDA was $38 million in the first quarter of 2026, versus $(42) million for the first quarter of 2025. The results reflect a stronger margin environment and recognition of clean fuel production tax credits due to clarity on 45Z regulation, partially offset by decreased utilization due to planned downtime at the Martinez Renewables joint venture facility, compared to the prior year quarter.

Corporate and Items Not Allocated

Corporate expenses totaled $274 million in the first quarter of 2026, compared with $210 million in the first quarter of 2025. The variance was primarily due to the fair value remeasurement of outstanding performance-based stock compensation driven by recent stock performance and environmental remediation expense related to historical operations at the Martinez refinery.

Financial Position, Liquidity, and Return of Capital

As of March 31, 2026, MPC had $2.2 billion of cash and cash equivalents, including $1.5 billion of cash at MPLX, and no borrowings outstanding under its $5 billion five-year bank revolving credit facility.

In the first quarter, the company returned over $1.0 billion of capital to shareholders. As of March 31, 2026, the company had $3.6 billion available under its share repurchase authorizations.

Additionally, the Board of Directors approved an incremental $5 billion share repurchase authorization. With the addition of this new authorization, the company would have had $8.6 billion available under its share repurchase authorizations as of March 31, 2026. The company may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated share repurchases, tender offers or open market solicitations for shares, some of which may be effected through Rule 10b5-1 plans. The timing of repurchases will depend upon several factors, including market and business conditions, and repurchases may be suspended or discontinued at any time.

Strategic Update

MPC’s 2026 capital spending outlook (excluding MPLX) is $1.5 billion. Approximately 65% of its overall spending is focused on value enhancing capital and 35% on sustaining capital. MPC’s outlook includes high-return investments at its Galveston Bay, Robinson, El Paso, and Garyville refineries. In the first quarter of 2026, the Garyville jet flexibility project was brought online. Modifications to the hydrocracker fractionator allow current products to be upgraded to higher value jet fuel, allowing the company to take advantage of growing domestic and export demand. In addition to these multi-year investments, the company is executing shorter-term projects that offer high returns through margin enhancement and cost reduction.

MPLX is investing 90% of its $2.4 billion organic growth capital plan toward opportunities to meet growing natural gas and NGL infrastructure needs. With projects concentrated in the Permian and Marcellus, two of the most prolific and competitive basins in North America, investments in these value chains reflect

MPLX’s confidence in the long-term fundamentals of the energy market, offer some of the most compelling investments in the midstream sector, and are expected to generate mid-teens returns.

(a) Excludes refining planned turnaround and depreciation and amortization expense.

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 Net Income Attributable to MPC and Adjusted Diluted Income Per Share

Adjusted net income attributable to MPC is defined as net income attributable to MPC excluding the items in the table below, along with their related income tax effect. We have excluded these items because we believe that they are not indicative of our core operating performance. Adjusted diluted income per share is defined as adjusted net income attributable to MPC divided by the number of weighted-average shares outstanding in the applicable period, assuming dilution.

We believe the use of adjusted net income attributable to MPC and adjusted diluted income per share provides us and our investors with important measures of our ongoing financial performance to better assess our underlying business results and trends. Adjusted net income attributable to MPC or adjusted diluted income per share should not be considered as a substitute for, or superior to net income attributable to MPC, diluted net income per share or any other measure of financial performance presented in accordance with GAAP. Adjusted net income attributable to MPC and adjusted diluted income per share may not be comparable to similarly titled measures reported by other companies.

Reconciliation of Net Income Attributable to MPC to Adjusted Net Income Attributable to MPC (unaudited)

(a) Recognition of 2025 clean fuel production tax credits as a result of proposed regulatory guidance issued in February of 2026 which clarified the qualification criteria for 45Z credits.

(b) Income taxes for the three months ended March 31, 2026 were calculated by applying a federal statutory rate and a blended state tax rate to the pre-tax adjustments. The corresponding adjustments to reported income taxes are shown in the table above.

15

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.

Reconciliation of Net Income Attributable to MPC to Adjusted EBITDA (unaudited)

(a) Recognition of 2025 clean fuel production tax credits as a result of proposed regulatory guidance issued in February of 2026 which clarified the qualification criteria for 45Z credits.

16

Refining & Marketing Margin

Refining & Marketing margin is defined as sales revenue less cost of refinery inputs and purchased products, which includes impacts from derivative activity. 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.

Reconciliation of Refining & Marketing Segment Adjusted EBITDA to Refining & Marketing Gross Margin and Refining & Marketing Margin (unaudited)

(a) Reflects the gross margin, excluding depreciation and amortization, of other related operations included in the Refining & Marketing segment and processing of credit card transactions on behalf of certain of our marketing customers, net of other income.

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 costs for purchased product, including from our Martinez Renewables JV. 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.
