FINDLAY, Ohio, Aug. 1, 2023 – Marathon Petroleum Corp. (NYSE: MPC) today reported net income attributable to MPC of $2.2 billion, or $5.32 per diluted share, for the second quarter of 2023, compared with net income attributable to MPC of $5.9 billion, or $10.95 per diluted share, for the second quarter of 2022.

The second quarter of 2023 adjusted earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA) was $4.5 billion, compared with $9.1 billion for the second quarter of 2022.

Adjusted EBITDA $ 4,531 $ 9,060 $ 9,749 $ 11,699

Refining & Marketing (R&M)

Segment adjusted EBITDA was $3.2 billion in the second quarter of 2023, versus $7.8 billion for the second quarter of 2022. Refining & Marketing segment adjusted EBITDA was $11.88 per barrel for the second quarter of 2023, versus $27.79 per barrel for the second quarter of 2022. Segment adjusted EBITDA excludes refining planned turnaround costs, which totaled $392 million in the second quarter of 2023 and $151 million in the second quarter of 2022. The decrease in segment adjusted EBITDA was driven primarily by lower R&M margins.

R&M margin was $22.10 per barrel for the second quarter of 2023, versus $37.54 per barrel for the second quarter of 2022. Crude capacity utilization was approximately 93%, driven by planned maintenance activity in the Mid-Continent and West Coast regions, resulting in total throughput of 2.9 million barrels per day for the second quarter of 2023.

Refining operating costs per barrel were $5.15 for the second quarter of 2023, versus $5.19 for the second quarter of 2022.

Midstream

Segment adjusted EBITDA was $1.53 billion in the second quarter of 2023, versus $1.46 billion for the second quarter of 2022, as growth in throughputs and higher rates more than offset lower natural gas liquids prices.

Corporate and Items Not Allocated

Corporate expenses totaled $183 million in the second quarter of 2023, which is flat sequentially, and higher compared with $170 million in the second quarter of 2022.

Discrete tax benefits in the second quarter 2023 tax provision included a $53 million benefit related to

prior years.

Financial Position, Liquidity, and Return of Capital

As of June 30, 2023, MPC had $11.5 billion of cash, cash equivalents, and short-term investments and $5 billion available on its bank revolving credit facility.

In the second quarter, the company returned approximately $3.4 billion of capital through $3.1 billion of share repurchases and $316 million of dividends. In July, the company repurchased $0.8 billion of company shares. The company has approximately $6.3 billion available under its share repurchase authorizations.

Strategic and Operations Update

At the Martinez Renewable Fuels facility, construction activities are progressing. Pretreatment capabilities are expected to come online in the second half of 2023, and the facility is expected to be capable of producing 730 million gallons per year by the end of 2023.

MPC completed the STAR project at its Galveston Bay refinery, which is expected to add 40,000 barrels per day of incremental crude capacity and 17,000 barrels per day of resid processing capacity.

MPC’s Midstream segment remains focused on executing the strategic priorities of strict capital discipline, fostering a low-cost culture, and optimizing the portfolio. MPLX is advancing growth projects anchored in the Marcellus, Permian and Bakken basins.

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

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 and that their exclusion results in an important measure of our ongoing financial performance to better assess our underlying business results and trends.

Adjusted Diluted Earnings Per Share

Adjusted diluted earnings 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.

Three Months Ended <br>June 30, Six Months Ended <br>June 30,
(In millions) 2023 2022 2023 2022
Net income attributable to MPC $ 2,226 $ 5,873 $ 4,950 $ 6,718
Pre-tax adjustments:
Renewable volume obligation requirements (238) (238)
Tax impact of adjustments(a) 52 52
Adjusted net income attributable to MPC $ 2,226 $ 5,687 $ 4,950 $ 6,532
Diluted income per share $ 5.32 $ 10.95 $ 11.44 $ 12.15
Adjusted diluted income per share $ 5.32 $ 10.61 $ 11.44 $ 11.81

(a)Income taxes for adjusted earnings for the three and six months ended June 30, 2022 were calculated by applying a combined federal and state statutory tax rate of 22% to the pre-tax adjustments. The corresponding adjustments to reported income taxes are shown in the table above.

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 believe this non-GAAP financial measure is used 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 calculations thereof may not be comparable to similarly titled measures reported by other companies.
