Notes to Consolidated Financial Statements (Unaudited)
1. Description of the Business and Basis of Presentation
Description of the Business
We are a leading, integrated, downstream and midstream energy company headquartered in Findlay, Ohio. We operate one of the nation's largest refining systems. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market and to independent entrepreneurs who operate branded outlets. We also sell transportation fuel to consumers through direct dealer locations under long-term supply contracts. MPC’s midstream operations are primarily conducted through MPLX, which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We own the general partner and a majority limited partner interest in MPLX. In addition, we produce and market renewable diesel in the United States.
Refer to Notes 3 and 9 for additional information about our operations.
Basis of Presentation
These interim consolidated financial statements are unaudited; however, in the opinion of our management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal, recurring nature unless otherwise disclosed. These interim consolidated financial statements, including the notes, have been prepared in accordance with the rules of the SEC applicable to interim period financial statements and do not include all of the information and disclosures required by GAAP for complete financial statements. Certain information and disclosures derived from our audited annual financial statements, prepared in accordance with GAAP, have been condensed or omitted from these interim financial statements.
These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the full year.
These consolidated financial statements include the accounts of our majority-owned, controlled subsidiaries, including MPLX. All significant intercompany transactions and accounts have been eliminated. Due to our ownership of the general partner interest of MPLX, we have determined that we control MPLX and therefore we consolidate MPLX and record a noncontrolling interest for the interest owned by the public. Changes in ownership interest in consolidated subsidiaries that do not result in a change in control are recorded as equity transactions. Investments in entities over which we have significant influence, but not control, are accounted for using the equity method of accounting. This includes entities in which we hold majority ownership but the minority shareholders have substantive participating rights.
In the fourth quarter of 2024, we established a Renewable Diesel segment, which includes renewable diesel activities historically reported in the Refining & Marketing segment. Prior period segment information has been recast for comparability. See Notes 9 and 17 for prior period recast information.
2. Accounting Standards and Disclosure Rules
Not Yet Adopted
ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued an ASU to require more detailed information about specified categories of expenses (purchases of inventory, employee compensation, depreciation, amortization, and depletion) included in certain expense captions presented on the face of the income statement. This ASU is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (2) retrospectively to all prior periods presented in the financial statements. We are currently evaluating the impact this ASU will have on our disclosures.
ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued an ASU to update income tax disclosure requirements to provide consistent categories and greater disaggregation of information in the rate reconciliation and to disaggregate income taxes paid by jurisdiction. This ASU is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis, but retrospective application is permitted. This ASU will result in additional disclosure.

3. Master Limited Partnership
We own the general partner and a majority limited partner interest in MPLX, which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We control MPLX through our ownership of the general partner interest and, as of June 30, 2025, we owned approximately 64 percent of the outstanding MPLX common units.
Unit Repurchase Program
On August 2, 2022, MPLX announced its board of directors approved a $1.0 billion unit repurchase authorization. This unit repurchase authorization has no expiration date. MPLX may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated unit repurchases, tender offers or open market solicitations for units, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be suspended, discontinued or restarted at any time.
Total unit repurchases were as follows for the respective periods:
| Three Months Ended June 30, | Six Months Ended June 30, | ||||||||||||||||||||||
| (In millions, except per unit data) | 2025 | 2024 | 2025 | 2024 | |||||||||||||||||||
| Number of common units repurchased | |||||||||||||||||||||||
| Cash paid for common units repurchased | $ | $ | $ | $ | |||||||||||||||||||
| Average cost per unit | $ | $ | $ | $ | |||||||||||||||||||
As of June 30, 2025, MPLX had approximately $320 million remaining under its unit repurchase authorization.
Preferred Units
The Series A preferred units are considered redeemable securities under GAAP due to the existence of redemption provisions upon a deemed liquidation event, which is outside MPLX’s control. Therefore, they are presented as temporary equity in the mezzanine section of our consolidated balance sheets.
During 2023 and 2024, certain Series A preferred unitholders exercised their rights to convert their Series A preferred units into common units. Approximately 6 million Series A preferred units were outstanding as of December 31, 2024. On February 11, 2025, MPLX exercised its right to convert the remaining outstanding Series A preferred units into common units.
For a summary of changes in the redeemable preferred balance, see the accompanying consolidated statements of equity and redeemable noncontrollable interest.
Agreements
We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX provides transportation, storage, distribution and marketing services to us. With certain exceptions, these agreements generally contain minimum volume commitments. These transactions are eliminated in consolidation but are reflected as intersegment transactions among our Refining & Marketing, Renewable Diesel and Midstream segments. We also have agreements with MPLX that establish fees for operational and management services provided between us and MPLX and for executive management services and certain general and administrative services provided by us to MPLX. These transactions are eliminated in consolidation but are reflected as intersegment transactions between corporate and our Midstream segment.
Noncontrolling Interest
As a result of equity transactions of MPLX, we are required to adjust non-controlling interest and additional paid-in capital. Changes in MPC’s additional paid-in capital resulting from changes in its ownership interests in MPLX were as follows:
| Three Months Ended June 30, | Six Months Ended June 30, | ||||||||||||||||||||||

4. Acquisitions and Other Transactions
Whiptail Midstream Acquisition
On March 11, 2025, MPLX acquired gathering businesses from Whiptail Midstream, LLC for $237 million in cash. These San Juan basin assets consist primarily of crude and natural gas gathering systems in the Four Corners region. The acquisition was accounted for as a business combination, which requires all the identifiable assets acquired and liabilities assumed to be remeasured to fair value at the date of acquisition. The preliminary determination of the fair value includes $172 million of property, plant and equipment, $41 million of intangibles and $24 million of net working capital. The allocation is subject to revision, as certain data necessary to complete the purchase price allocation is not yet available, including, but not limited to, the final valuation of assets acquired and liabilities assumed. The final valuation will be completed no later than one year from the acquisition date. The results for the acquired business are reported within our Midstream segment.
Whistler Joint Venture Transaction
On May 29, 2024, MPLX and its joint venture partner contributed their respective membership interest in Whistler Pipeline, LLC to a newly formed joint venture, WPC Parent, LLC, and issued a 19 percent voting interest in WPC Parent, LLC to an affiliate of Enbridge Inc. in exchange for the contribution of cash and the Rio Bravo Pipeline project (collectively the “Whistler Joint Venture Transaction”). As a result of the transaction, MPLX’s voting interest in the joint venture was reduced from 37.5 percent to 30.4 percent. MPLX recognized a gain of $151 million at closing and received a cash distribution of $134 million, recorded as a return of capital, related to the dilution of the ownership interest. The gain is included in income from equity method investments on the accompanying consolidated statements of income and the return of capital is included in investments - redemptions, repayments, return of capital and sales proceeds within the investing section of the accompanying consolidated statements of cash flows.
Utica Midstream Acquisition
On March 22, 2024, MPLX used $625 million of cash to purchase additional ownership interest in existing joint ventures and gathering assets, which will enhance MPLX’s position in the Utica basin. Prior to the acquisition, MPLX owned an indirect interest in Ohio Gathering Company, L.L.C. (“OGC”) and a direct interest in Ohio Condensate Company, L.L.C. (“OCC”). After giving effect to the acquisition, MPLX owns a combined direct and indirect 73 percent interest in OGC and a 100 percent interest in OCC. In addition, MPLX acquired a 100 percent interest in a dry gas gathering system in the Utica basin. OGC continues to be accounted for as an equity method investment as MPLX did not obtain control of OGC as a result of the transaction. OGC is considered a VIE and MPLX is not deemed to be the primary beneficiary due to voting rights on significant matters. The acquisition date fair value of our investment in OGC exceeded our portion of the underlying net assets of the joint venture by approximately $75 million. This basis difference is being amortized into net income over the remaining estimated useful lives of the underlying net assets. OCC was previously accounted for as an equity method investment, and it is now consolidated and included in our consolidated financial results.
The acquisition was accounted for as a business combination requiring all the acquired assets and liabilities to be remeasured to fair value resulting in a consolidated fair value of net assets and liabilities of $625 million. The fair value includes $507 million related to acquired interests in the joint ventures and the remaining balance related to other acquired assets and liabilities. The revaluation of MPLX’s existing 62 percent equity method investment in OCC resulted in a $20 million gain, which is included in net gain on disposal of assets on the accompanying consolidated statements of income. The fair value of equity method investments was based on a discounted cash flow model.
5. Variable Interest Entities
Consolidated VIE
We control MPLX through our ownership of its general partner. MPLX is a VIE because the limited partners do not have substantive kick-out or participating rights over the general partner. We are the primary beneficiary of MPLX because in addition to our significant economic interest, we also have the ability, through our ownership of the general partner, to control the decisions that most significantly impact MPLX. We therefore consolidate MPLX and record a noncontrolling interest for the interest owned by the public.
The creditors of MPLX do not have recourse to MPC’s general credit or assets through guarantees or other financial arrangements, except as otherwise noted. MPC has effectively guaranteed certain indebtedness of LOOP LLC (“LOOP”) and LOCAP LLC (“LOCAP”), in which MPLX holds an interest. See Note 22 for more information. The assets of MPLX can only be used to settle its own obligations and any rights of MPC’s creditors to participate in the assets of MPLX are subject to prior claims of MPLX’s creditors.

Sales to related parties, which are included in sales and other operating revenues, consist primarily of refined product sales and renewable feedstock sales to certain of our equity affiliates.
7. Earnings Per Share
We compute basic earnings per share by dividing net income attributable to MPC less income allocated to participating securities by the weighted average number of shares of common stock outstanding. Since MPC grants certain incentive compensation awards to employees and non-employee directors that are considered to be participating securities, we have calculated our earnings per share using the two-class method. Diluted income per share assumes exercise of certain share-based compensation awards, provided the effect is not anti-dilutive.

8. Equity
On November 5, 2024, MPC announced that our board of directors approved a $5.0 billion share repurchase authorization in addition to the $5.0 billion share repurchase authorization announced on April 30, 2024. As of June 30, 2025, $6.03 billion remained available for repurchase under the share repurchase authorizations. These share repurchase authorizations have no expiration date.
We 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 and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be suspended, discontinued or restarted at any time.
Total share repurchases were as follows for the respective periods:

(b) The average cost per share includes excise tax on share repurchases resulting from the Inflation Reduction Act of 2022, but the excise tax does not reduce the remaining share repurchase authorization.

9. Segment Information
We have three reportable segments: Refining & Marketing, Midstream and Renewable Diesel. Each of these segments is organized and managed based upon the nature of the products and services it offers.
•Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to independent entrepreneurs who operate primarily Marathon® branded outlets and through long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO® brand.
•Midstream – gathers, transports, stores and distributes crude oil, refined products, including renewable diesel, and other hydrocarbon-based products principally for the Refining & Marketing segment via refining logistics assets, pipelines, terminals, towboats and barges; gathers, processes and transports natural gas; and transports, fractionates, stores and markets NGLs. The Midstream segment primarily reflects the results of MPLX.
•Renewable Diesel – processes renewable feedstocks into renewable diesel, markets renewable diesel and distributes renewable products through our Midstream segment and third parties. We sell renewable diesel to wholesale marketing customers, to buyers on the spot market and through long-term supply contracts with direct dealers who operate locations mainly under the ARCO® brand.
Our chief operating decision maker (“CODM”) evaluates the performance of our segments using segment adjusted EBITDA. Our CODM is our chief executive officer. The CODM uses adjusted EBITDA by segment results when making decisions about allocating capital and personnel as part of the annual business plan process and ongoing monitoring of performance. Amounts included in income before income taxes and excluded from adjusted EBITDA include: (i) depreciation and amortization; (ii) net interest and other financial costs; (iii) turnaround expenses; and (iv) other adjustments as deemed necessary. These items are either: (i) believed to be non-recurring in nature; (ii) not believed to be allocable or controlled by the segment; or (iii) not tied to the operational performance of the segment. Assets by segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures.

11. Income Taxes
We recorded a combined federal, state and foreign income tax provision of $268 million and $305 million for the three and six months ended June 30, 2025, respectively, which was lower than the U.S. statutory rate primarily due to permanent tax benefits related to net income attributable to noncontrolling interests, partially offset by state taxes.
We recorded a combined federal, state and foreign income tax provision of $373 million and $666 million for the three and six months ended June 30, 2024, respectively, which was lower than the U.S. statutory rate primarily due to permanent tax benefits related to net income attributable to noncontrolling interests, partially offset by state taxes.
On July 4, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act contains a multitude of provisions with various effective dates, with certain provisions effective in 2025. The provisions that are currently expected to affect us include the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, tax relief measures including 100 percent bonus depreciation for property acquired and placed in service on or after January 19, 2025, and modifications to the international tax framework. We are currently assessing its impact on our consolidated financial statements.

14. Fair Value Measurements
Fair Values—Recurring
The following tables present assets and liabilities accounted for at fair value on a recurring basis as of June 30, 2025 and December 31, 2024 by fair value hierarchy level. We have elected to offset the fair value amounts recognized for multiple derivative contracts executed with the same counterparty, including any related cash collateral as shown below; however, fair value amounts by hierarchy level are presented on a gross basis in the following tables.

As of June 30, 2025, cash collateral of $42 million was netted with mark-to-market derivative liabilities. As of December 31, 2024, cash collateral of $12 million was netted with mark-to-market derivative liabilities.
(b)We have no derivative contracts which are subject to master netting arrangements reflected gross on the balance sheet.
Level 3 instruments relate to an embedded derivative liability for a natural gas purchase commitment embedded in a keep‑whole processing agreement. The fair value calculation for these Level 3 instruments at June 30, 2025 used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.68 to $1.27 per gallon with a weighted average of $0.81 per gallon and (2) a 100 percent probability of renewal for the -year term of the natural gas purchase commitment and related keep-whole processing agreement. Increases or decreases in the fractionation spread result in an increase or decrease in the fair value of the embedded derivative liability.
The following is a reconciliation of the beginning and ending balances recorded for net liabilities classified as Level 3 in the fair value hierarchy.

Fair Values – Non-recurring
Non-recurring fair value measurements and disclosures relate to acquisitions and other transactions as discussed in Note 4.
Fair Values – Reported
We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, accounts payable and certain accrued liabilities, approximate fair value. Our fair value assessment incorporates a variety of considerations, including the short-term duration of the instruments and the expected insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. The borrowings under our revolving credit facilities, which include variable interest rates, approximate fair value. The fair value of our long-term debt is based on prices from recent trade activity and is categorized in level 3 of the fair value hierarchy. The carrying and fair values of our debt were approximately $28.1 billion and $26.4 billion at June 30, 2025, respectively, and approximately $26.9 billion and $25.0 billion at December 31, 2024, respectively. These carrying and fair values of our debt exclude the unamortized issuance costs, which are netted against our total debt.
15. Derivatives
For further information regarding the fair value measurement of derivative instruments, including any effect of master netting agreements or collateral, see Note 14. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.
Derivatives that are not designated as accounting hedges may include commodity derivatives used to hedge price risk on (1) inventories, (2) fixed price sales of refined products, (3) the acquisition of foreign-sourced crude oil, (4) the acquisition of
19
ethanol for blending with refined products, (5) the sale of NGLs, (6) the purchase of natural gas and (7) the purchase of soybean oil.
The following table presents the fair value of derivative instruments as of June 30, 2025 and December 31, 2024 and the line items in the consolidated balance sheets in which the fair values are reflected. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under the terms of our master netting arrangements including cash collateral on deposit with, or received from, brokers. We offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements when a legal right of offset exists. As a result, the asset and liability amounts below will not agree with the amounts presented in our consolidated balance sheets.

During the six months ended June 30, 2025, we made contributions of $36 million to our funded pension plans. Benefit payments related to unfunded pension and other postretirement benefit plans were $4 million and $26 million, respectively, during the six months ended June 30, 2025.
22. Commitments and Contingencies
We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Some of these matters are discussed below. For matters for which we have not recorded a liability, we are unable to estimate a range of possible loss because the issues involved have not been fully developed through pleadings, discovery or court proceedings. However, the ultimate resolution of some of these contingencies could, individually or in the aggregate, be material.
Environmental Matters
We are subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites and certain other locations including presently or formerly owned or operated retail marketing sites. Penalties may be imposed for noncompliance.
At June 30, 2025 and December 31, 2024, accrued liabilities for remediation totaled $347 million and $364 million, respectively. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties, if any, that may be imposed. Receivables for recoverable costs from certain states, under programs to assist companies in clean-up efforts related to underground storage tanks at presently or formerly owned or operated retail marketing sites, were $4 million and $6 million at June 30, 2025 and December 31, 2024, respectively.
Governmental and other entities in various states have filed climate-related lawsuits against a number of energy companies, including MPC. Although each suit is separate and unique, the lawsuits generally allege defendants made knowing misrepresentations about knowingly concealing, or failing to warn of the impacts of their petroleum products which led to increased demand and worsened climate change. Plaintiffs are seeking unspecified damages and abatement under various tort theories, as well as breaches of consumer protection and unfair trade statutes. We are currently subject to such proceedings in federal or state courts in California, Delaware, Maryland, Hawaii, South Carolina and Oregon. Similar lawsuits may be filed in other jurisdictions. At this early stage, the ultimate outcome of these matters remains uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined.
24
We are involved in a number of environmental enforcement matters arising in the ordinary course of business. While the outcome and impact on us cannot be predicted with certainty, management believes the resolution of these environmental matters will not, individually or collectively, have a material adverse effect on our consolidated results of operations, financial position or cash flows.
Other Legal Proceedings
In July 2020, Tesoro High Plains Pipeline Company, LLC (“THPP”), a subsidiary of MPLX, received a Notification of Trespass Determination from the Bureau of Indian Affairs (“BIA”) relating to a portion of the Tesoro High Plains Pipeline that crosses the Fort Berthold Reservation in North Dakota. The notification demanded the immediate cessation of pipeline operations and assessed trespass damages of approximately $187 million. After subsequent appeal proceedings and in compliance with a new order issued by the BIA, in December 2020, THPP paid approximately $4 million in assessed trespass damages and ceased use of the portion of the pipeline that crosses the property at issue. In March 2021, the BIA issued an order purporting to vacate the BIA’s prior orders related to THPP’s alleged trespass and direct the Regional Director of the BIA to reconsider the issue of THPP’s alleged trespass and issue a new order. In April 2021, THPP filed a lawsuit in the District of North Dakota against the United States of America, the U.S. Department of the Interior and the BIA (collectively, the “U.S. Government Parties”) challenging the March 2021 order purporting to vacate all previous orders related to THPP’s alleged trespass. On February 8, 2022, the U.S. Government Parties filed their answer and counterclaims to THPP’s suit claiming THPP is in continued trespass with respect to the pipeline and seek disgorgement of pipeline profits from June 1, 2013 to present, removal of the pipeline and remediation. On November 8, 2023, the District Court of North Dakota granted THPP’s motion to sever and stay the U.S. Government Parties’ counterclaims. The case will proceed on the merits of THPP’s challenge to the March 2021 order purporting to vacate all previous orders related to THPP’s alleged trespass. THPP continues not to operate that portion of the pipeline that crosses the property at issue.
We are also a party to a number of other lawsuits and other proceedings arising in the ordinary course of business. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe that the resolution of these other lawsuits and proceedings will not, individually or collectively, have a material adverse effect on our consolidated financial position, results of operations or cash flows.
Guarantees
We have provided certain guarantees, direct and indirect, of the indebtedness of other companies. Under the terms of most of these guarantee arrangements, we would be required to perform should the guaranteed party fail to fulfill its obligations under the specified arrangements. In addition to these financial guarantees, we also have various performance guarantees related to specific agreements.
Guarantees related to indebtedness of equity method investees
LOOP and LOCAP
MPC and MPLX hold interests in an offshore oil port, LOOP, and MPLX holds an interest in a crude oil pipeline system, LOCAP. Both LOOP and LOCAP have secured various project financings with throughput and deficiency agreements. Under the agreements, MPC, as a shipper, is required to advance funds if the investees are unable to service their debt. Any such advances are considered prepayments of future transportation charges. The duration of the agreements varies but tends to follow the terms of the underlying debt, which extend through 2040. Our maximum potential undiscounted payments under these agreements for the debt principal totaled $214 million as of June 30, 2025.
Dakota Access Pipeline
MPLX holds a 9.19 percent indirect interest in a joint venture (“Dakota Access”), which owns and operates the Dakota Access Pipeline and Energy Transfer Crude Oil Pipeline projects (collectively, the “Bakken Pipeline system”). In 2020, the U.S. District Court for the District of Columbia (the “D.D.C.”) ordered the U.S. Army Corps of Engineers (“Army Corps”), which granted permits and an easement for the Bakken Pipeline system, to prepare an environmental impact statement (“EIS”) relating to an easement under Lake Oahe in North Dakota. The D.D.C. later vacated the easement. The Army Corps issued a draft EIS in September 2023 detailing various options for the easement going forward, including denying the easement, approving the easement with additional measures, rerouting the easement, or approving the easement with no changes. The Army Corps has not selected a preferred alternative, but will make a decision in its final review, after considering input from the public and other agencies. The pipeline remains operational while the Army Corps finalizes its decision which will follow the issuance of the final EIS. According to public statements from Army Corps officials, the EIS is now expected to be issued in 2025.
MPLX has entered into a Contingent Equity Contribution Agreement whereby it, along with the other joint venture owners in the Bakken Pipeline system, has agreed to make equity contributions to the joint venture upon certain events occurring to allow the entities that own and operate the Bakken Pipeline system to satisfy their senior note payment obligations. The senior notes were issued to repay amounts owed by the pipeline companies to fund the cost of construction of the Bakken Pipeline system. If the vacatur of the easement results in a temporary shutdown of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of funds required to pay interest accruing on the notes and any portion of the principal that matures while the pipeline is shut down. MPLX also expects to contribute its 9.19 percent pro rata share of any costs to remediate any deficiencies to reinstate the easement and/or return the pipeline into operation. If the vacatur of the easement results in a permanent shutdown
25
of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds (including the 1 percent redemption premium required pursuant to the indenture governing the notes) and any accrued and unpaid interest. As of June 30, 2025, our maximum potential undiscounted payments under the Contingent Equity Contribution Agreement were approximately $78 million.
Other guarantees
We have entered into other guarantees with maximum potential undiscounted payments totaling $226 million as of June 30, 2025, which primarily consist of a commitment to indemnify a joint venture member for our pro rata share of any payments made under a performance guarantee for construction of a pipeline by an equity method investee, a commitment to contribute cash to an equity method investee for certain catastrophic events in lieu of procuring insurance coverage, a payment guaranty of an unsecured bank term loan for which BANGL, LLC (“BANGL”) was the borrower and obligor, a commitment to pay a termination fee on a supply agreement if terminated during the initial term, a commitment to fund a share of the bonds issued by a government entity for construction of public utilities in the event that other industrial users of the facility default on their utility payments and leases of assets containing general lease indemnities and guaranteed residual values. On July 1, 2025, MPLX purchased the remaining 55 percent interest in BANGL and the payment guaranty of BANGL’s outstanding bank term loan was effectively terminated.
Contractual Commitments and Contingencies
23. Subsequent Events
BANGL, LLC Acquisition
On July 1, 2025, MPLX purchased the remaining 55 percent interest in BANGL that was previously held by MPLX’s joint venture partners for approximately $700 million, plus an earnout provision of up to $275 million (the “BANGL Acquisition”). The earnout provision requires annual payments based on targeted EBITDA growth from 2026 to 2029 up to the maximum amount of $275 million. As a result of the BANGL Acquisition, MPLX now owns 100 percent of BANGL and its results will be reflected in our Midstream segment within our consolidated financial results beginning in the third quarter of 2025. The BANGL Acquisition will be accounted for as a business combination, resulting in an estimated gain in excess of $400 million, which will be recognized in the third quarter of 2025 upon finalizing the initial accounting and provisional fair value measurements of BANGL’s assets and liabilities.
Subsequent to closing this transaction, on July 3, 2025, MPLX used cash on hand to extinguish approximately $656 million of debt principal outstanding, including interest, related to certain term and revolving loans assumed as part of the BANGL Acquisition.
Sale of Interest in Ethanol Joint Venture
On July 31, 2025, MPC sold its 49.9 percent interest in The Andersons Marathon Holdings LLC (“TAMH”) to The Andersons Ethanol LLC, in exchange for cash proceeds of $425 million. MPC’s investment in TAMH was accounted for as an equity method investment reported within MPC’s Refining & Marketing segment. Upon disposal, MPC de-recognized its investment in TAMH, resulting in an estimated gain of $245 million to be recognized in the third quarter of 2025.
Additional $1.0 Billion MPLX Unit Repurchase Authorization
On August 5, 2025, MPLX announced that its board of directors approved an incremental $1.0 billion common unit repurchase authorization. The authorization has no expiration date. MPLX may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated unit repurchases, tender offers or open market solicitations for units, 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, discontinued or restarted at any time.

EXECUTIVE SUMMARY
Business Update
Our refining results for the second quarter of 2025 versus the second quarter of 2024 reflect stable demand and comparable realized refining margins despite a weaker margin environment year-over-year. Longer term, global demand growth is expected to outpace the net impact of refining capacity additions and rationalizations through the end of the decade. We anticipate these fundamentals, as well as the U.S. refining industry’s current structural advantages over the rest of the world, will support a constructive environment for U.S. refiners.
Our Midstream segment contributed strong results and continued growth in the second quarter of 2025. As demand increases for natural gas-powered electricity and LNG exports, we believe our Midstream business is well positioned and has significant opportunities to support the development plans of its producer customers.

Strategic Updates
Midstream Growth Transactions
Northwind Midstream Acquisition
MPLX entered into a definitive agreement in July 2025 to acquire Northwind Midstream for $2.375 billion in cash consideration, subject to purchase price adjustments for reimbursement of capital expenses paid by Northwind Midstream from June 1, 2025 through the closing date, in addition to other customary adjustments. Northwind Midstream provides sour gas gathering, treating, and processing services in Lea County, New Mexico. The transaction, which MPLX intends to finance with debt, is expected to close in the third quarter of 2025, subject to the satisfaction or waiver of customary closing conditions, including regulatory approval.
BANGL, LLC Acquisition
On July 1, 2025, MPLX purchased the remaining 55 percent interest in BANGL, LLC (“BANGL”) that was previously held by MPLX’s joint venture partners for approximately $700 million, plus an earnout provision of up to $275 million (the “BANGL Acquisition”). The earnout provision requires annual payments based on targeted EBITDA growth from 2026 to 2029 up to the maximum amount of $275 million. As a result of this transaction, MPLX now owns 100 percent of BANGL and its results will be reflected in our Midstream segment within our consolidated financial results beginning in the third quarter of 2025. The acquisition will be accounted for as a business combination, resulting in an estimated gain in excess of $400 million, which will be recognized in the third quarter of 2025 upon finalizing the initial accounting and provisional fair value measurements of BANGL’s assets and liabilities.
See Note 23 to the unaudited consolidated financial statements for additional information on this transaction.
Whiptail Midstream Acquisition
On March 11, 2025, MPLX acquired gathering businesses from Whiptail Midstream, LLC for $237 million in cash. These San Juan basin assets consist primarily of crude and natural gas gathering systems in the Four Corners region. The acquisition was accounted for as a business combination, which requires all the identifiable assets acquired and liabilities assumed to be remeasured to fair value at the date of acquisition. The preliminary determination of the fair value includes $172 million of property, plant and equipment, $41 million of intangibles and $24 million of net working capital. The preliminary values are subject to revision and may result in adjustments as valuations are finalized.
See Note 4 to the unaudited consolidated financial statements for additional information on this transaction.
Sale of Interest in Ethanol Joint Venture
On July 31, 2025, MPC sold its 49.9 percent interest in The Andersons Marathon Holdings LLC (“TAMH”) to The Andersons Ethanol LLC, in exchange for cash proceeds of $425 million. MPC’s investment in TAMH was accounted for as an equity method investment reported within MPC’s Refining & Marketing segment. Upon disposal, MPC de-recognized its investment in TAMH, resulting in an estimated gain on sale of $245 million to be recognized in the third quarter of 2025.

MPLX
We owned approximately 647 million MPLX common units as of June 30, 2025, with a market value of $33.35 billion based on the June 30, 2025 closing price of $51.51 per common unit. On July 29, 2025, MPLX declared a quarterly cash distribution of $0.9565 per common unit payable on August 15, 2025 to unitholders of record on August 8, 2025. MPC’s portion of this distribution is approximately $620 million.
We received limited partner distributions of $1.24 billion from MPLX in the six months ended June 30, 2025 and $1.10 billion in the six months ended June 30, 2024.
During the six months ended June 30, 2025, MPLX repurchased approximately 4 million MPLX common units at an average cost per unit of $51.38 and paid $200 million of cash for the repurchased common units. As of June 30, 2025, approximately $320 million remained available under the authorization for future unit repurchases.
See Note 3 to the unaudited consolidated financial statements for additional information on MPLX.

OVERVIEW OF SEGMENTS
Refining & Marketing
Refining & Marketing segment adjusted EBITDA depends largely on our refinery throughputs, Refining & Marketing margin, refining operating costs and distribution costs.
Refining & Marketing margin is the difference between the prices of refined products sold and the costs of crude oil and other charge and blendstocks refined, including the costs to transport these inputs to our refineries and the costs of products purchased for resale. The crack spread is a measure of the difference between market prices for refined products and crude oil, commonly used by the industry as a proxy for the refining margin. Crack spreads can fluctuate significantly, particularly when prices of refined products do not move in the same relationship as the cost of crude oil. As a performance benchmark and a comparison with other industry participants, we calculate Gulf Coast, Mid-Continent and West Coast crack spreads that we believe most closely track our operations and slate of products. The following are used for these crack spread calculations:
•The Gulf Coast crack spread uses three barrels of MEH crude producing two barrels of USGC CBOB gasoline and one barrel of USGC ULSD;
•The Mid-Continent crack spread uses three barrels of WTI crude producing two barrels of Chicago CBOB gasoline and one barrel of Chicago ULSD; and
•The West Coast crack spread uses three barrels of ANS crude producing two barrels of LA CARBOB and one barrel of LA CARB diesel.
Our refineries can process a variety of sweet and sour crude oil, which typically can be purchased at a discount to crude oil referenced in our Gulf Coast, Mid-Continent and West Coast crack spreads. The amount of these discounts, which we refer to as the sweet differential and the sour differential, can vary significantly, causing our Refining & Marketing margin to differ from blended crack spreads. In general, larger sweet and sour differentials will enhance our Refining & Marketing margin.
Future crude oil differentials will be dependent on a variety of market and economic factors, as well as U.S. energy policy.
The following table provides sensitivities showing an estimated change in annual Refining & Marketing segment adjusted EBITDA due to potential changes in market conditions.
| (Millions of dollars) | ||||||||
Blended crack spread sensitivity(a) (per $1.00/barrel change) | $ | 1,100 | ||||||
Sour differential sensitivity(b) (per $1.00/barrel change) | 515 | |||||||
Sweet differential sensitivity(c) (per $1.00/barrel change) | 515 | |||||||
Natural gas price sensitivity(d) (per $1.00/MMBtu) | 350 | |||||||
(a)Crack spread based on 42 percent MEH, 40 percent WTI and 18 percent ANS with Gulf Coast, Mid-Continent and West Coast product pricing, respectively, and assumes all other differentials and pricing relationships remain unchanged.
(b)Sour crude oil basket consists of the following crudes: ANS, Argus Sour Crude Index, Maya and Western Canadian Select. We assume approximately 50 percent of the crude processed at our refineries in 2025 will be sour crude.
(c)Sweet crude oil basket consists of the following crudes: Bakken, Brent, MEH, WTI-Cushing and WTI-Midland. We assume approximately 50 percent of the crude processed at our refineries in 2025 will be sweet crude.
(d)This is consumption-based exposure for our Refining & Marketing segment and does not include the sales exposure for our Midstream segment.
In addition to the market changes indicated by the crack spreads, the sour differential and the sweet differential, our Refining & Marketing margin is impacted by factors such as:
•the selling prices realized for refined products;
•the types of crude oil and other charge and blendstocks processed;
•our refinery yields;
•the cost of products purchased for resale;
•the impact of commodity derivative instruments used to hedge price risk;
•the potential impact of lower of cost or market adjustments to inventories in periods of declining prices;
•the potential impact of LIFO adjustments due to changes in historic inventory levels; and
•the cost of purchasing RINs in the open market to comply with RFS2 requirements.
Refining & Marketing segment adjusted EBITDA is also affected by changes in refining operating costs in addition to committed distribution costs. Changes in operating costs are primarily driven by the cost of energy used by our refineries, including purchased natural gas, and the level of maintenance costs. Distribution costs primarily include long-term agreements with MPLX, which as discussed below include minimum commitments to MPLX, and will negatively impact segment adjusted EBITDA in periods when throughput or sales are lower or refineries are idled.
31
We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX, which is reported in our Midstream segment, provides transportation, storage, distribution and marketing services to our Refining & Marketing segment. Certain of these agreements include commitments for minimum quarterly throughput and distribution volumes of crude oil and refined products and minimum storage volumes of crude oil, refined products and other products. Certain other agreements include commitments to pay for 100 percent of available capacity for certain marine transportation and refining logistics assets.
Midstream
Our Midstream segment gathers, transports, stores and distributes crude oil, refined products, including renewable diesel, and other hydrocarbon-based products, principally for our Refining & Marketing segment. Additionally, the segment markets refined products. The profitability of our pipeline transportation operations primarily depends on tariff rates and the volumes shipped through the pipelines. The profitability of our marine operations primarily depends on the quantity and availability of our vessels and barges. The profitability of our light product terminal operations primarily depends on the throughput volumes at these terminals. The profitability of our fuels distribution services primarily depends on the sales volumes of certain refined products. The profitability of our refining logistics operations depends on the quantity and availability of our refining logistics assets. A majority of the crude oil and refined product shipments on our pipelines and marine vessels and the refined product throughput at our terminals serve our Refining & Marketing segment and our refining logistics assets and fuels distribution services are used solely by our Refining & Marketing segment. As discussed above in the Refining & Marketing section, MPLX, which is reported in our Midstream segment, has various long-term, fee-based commercial agreements related to services provided to our Refining & Marketing segment. Under these agreements, MPLX has received various commitments of minimum throughput, storage and distribution volumes as well as commitments to pay for all available capacity of certain assets. The volume of crude oil that we transport is directly affected by the supply of, and refiner demand for, crude oil in the markets served directly by our crude oil pipelines, terminals and marine operations. Key factors in this supply and demand balance are the production levels of crude oil by producers in various regions or fields, the availability and cost of alternative modes of transportation, the volumes of crude oil processed at refineries and refinery and transportation system maintenance levels. The volume of refined products that we transport, store, distribute and market is directly affected by the production levels of, and user demand for, refined products in the markets served by our refined product pipelines and marine operations. In most of our markets, demand for gasoline and distillate peaks during the summer driving season, which extends from May through September of each year, and declines during the fall and winter months. As with crude oil, other transportation alternatives and system maintenance levels influence refined product movements.
Our Midstream segment also gathers, processes and transports natural gas and transports, fractionates, stores and markets NGLs. NGL and natural gas prices are volatile and are impacted by changes in fundamental supply and demand, as well as market uncertainty, availability of NGL transportation and fractionation capacity and a variety of additional factors that are beyond our control. Our Midstream segment profitability is affected by prevailing commodity prices primarily as a result of processing or conditioning at our own or third‑party processing plants, purchasing and selling or gathering and transporting volumes of natural gas at index‑related prices and the cost of third‑party transportation and fractionation services. To the extent that commodity prices influence the level of natural gas drilling by our producer customers, such prices also affect profitability.
Renewable Diesel
Our Renewable Diesel segment processes renewable feedstocks into renewable diesel, markets and distributes renewable diesel and includes joint ventures that produce soybean oil and renewable diesel.
Our Renewable Diesel segment adjusted EBITDA is affected by changes in operating costs, distribution costs, throughput and certain regulatory credits.

Second Quarter 2025 Compared to Second Quarter 2024
Net income attributable to MPC decreased $299 million in the second quarter of 2025 compared to the second quarter of 2024 primarily due to the following:
Revenues and other income decreased $4.26 billion primarily due to:
•decreased sales and other operating revenues of $4.12 billion mainly due to a decrease in Refining & Marketing segment average refined product sales prices of $0.33 per gallon, partially offset by increased refined product sales volumes of 129 mbpd; and
•decreased income from equity method investments of $161 million largely due to the absence of the gain on sale of assets resulting from the Whistler Joint Venture Transaction in the second quarter of 2024.
Costs and expenses decreased $3.94 billion primarily due to:
•decreased cost of revenues of $3.92 billion mainly due to lower crude oil costs;
•decreased depreciation and amortization of $49 million largely due to major refining assets that were fully depreciated at the end of 2024; and
•increased selling, general and administrative expenses of $44 million primarily due to changes in fair value of equity compensation of $36 million, and increases in salaries and employee related expenses of $26 million and contract services costs of $10 million, partially offset by the absence of $30 million of expense in the second quarter of 2024 related to decommissioning of non-operating assets.
33
Net interest and other financial costs increased $125 million largely due to decreased interest income and discount amortization, primarily due to the absence of short-term investments held in the second quarter of 2024, and increases in interest expense and non-service pension costs.
We recorded combined federal, state and foreign income tax provisions of $268 million and $373 million for the three months ended June 30, 2025 and 2024, respectively, which were lower than the U.S. statutory rate primarily due to permanent tax benefits related to net income attributable to noncontrolling interests, partially offset by state taxes.
Net income attributable to noncontrolling interests decreased $41 million mainly due to a decrease in MPLX’s net income in the second quarter of 2025. See further discussion in the Midstream Segment Results section.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Net income attributable to MPC decreased $1.31 billion in the first six months of 2025 compared to the first six months of 2024 primarily due to the following:
Revenues and other income decreased $5.62 billion primarily due to:
•decreased sales and other operating revenues of $5.30 billion mainly due to a decrease in Refining & Marketing segment average refined product sales prices of $0.27 per gallon, partially offset by increased refined product sales volumes of 168 mbpd;
•decreased income from equity method investments of $135 million largely due to the absence of the gain on sale of assets resulting from the Whistler Joint Venture Transaction in the first six months of 2024; and
•decreased other income of $170 million mainly due to the absence of insurance proceeds in the first six months of 2024.
Costs and expenses decreased $4.20 billion primarily due to:
•decreased cost of revenues of $4.15 billion mainly due to lower crude oil costs;
•decreased depreciation and amortization of $83 million largely due to major refining assets that were fully depreciated at the end of 2024; and
•increased selling, general and administrative expenses of $48 million largely due to increases in salaries and employee related expenses of $49 million, contract services costs of $22 million and office expenses of $22 million, partially offset by the absence of $30 million of expense in the first six months of 2024 related to decommissioning of non-operating assets.
Net interest and other financial costs increased $250 million largely due to decreased interest income and discount amortization, primarily due to the absence of short-term investments held in the first six months of 2024, and increases in non-service pension costs and interest expense.
We recorded combined federal, state and foreign income tax provisions of $305 million and $666 million for the six months ended June 30, 2025 and 2024, respectively, which were lower than the U.S. statutory rate primarily due to permanent tax benefits related to net income attributable to noncontrolling interests, partially offset by state taxes.

Second Quarter 2025 Compared to Second Quarter 2024
Refining & Marketing segment revenues decreased $4.37 billion primarily due to a decrease in average refined product sales prices of $0.33 per gallon, partially offset by increased refined product sales volumes of 129 mbpd.
Refining & Marketing segment adjusted EBITDA decreased $132 million mainly due to increased refining operating and distribution costs, both excluding depreciation and amortization, partially offset by increased per barrel margins. Refining & Marketing segment adjusted EBITDA was $6.79 per barrel for the second quarter of 2025, versus $7.28 per barrel for the second quarter of 2024.
Refining & Marketing margin was $17.58 per barrel for the second quarter of 2025 compared to $17.53 per barrel for the second quarter of 2024. Refining & Marketing margin is affected by our performance against the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately $500 million on Refining & Marketing margin for the second quarter of 2025 compared to the second quarter of 2024, primarily due to narrower sour and sweet crude oil differentials and lower crack spreads. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, the effect of market structure on our crude oil acquisition prices, the effect of RIN prices on the crack spread, and other items like refinery yields, other feedstock variances and fuel margin from sales to direct dealers. These factors had an estimated net positive effect of approximately $500 million on Refining & Marketing segment adjusted EBITDA in the second quarter of 2025 compared to the second quarter of 2024.
For the three months ended June 30, 2025, refining operating costs, excluding depreciation and amortization, increased $123 million, or $0.43 per barrel, largely due to higher energy costs.
Distribution costs, excluding depreciation and amortization, increased $43 million, or $0.14 per barrel, and include fees paid to MPLX of $1.0 billion and $990 million for the second quarter of 2025 and 2024, respectively.
Refining planned turnaround costs increased $0.24 per barrel, or $68 million, due to the scope and timing of turnaround activity.
We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased RINs were $314 million and $293 million in the second quarter of 2025 and 2024, respectively. The RINs expense is included in Refining & Marketing margin. The increase in the second quarter of 2025 was mainly due to increased obligated volumes and higher average RIN prices, partially offset by higher RINs generated and acquired from our Martinez Renewables joint venture and lower sale activity.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Refining & Marketing segment revenues decreased $5.89 billion primarily due to a decrease in average refined product sales prices of $0.27 per gallon, partially offset by increased refined product sales volumes of 168 mbpd.
Net refinery throughput increased 101 mbpd in the first six months of 2025 largely due to decreased turnaround activity.
Refining & Marketing segment adjusted EBITDA decreased $1.63 billion mainly driven by decreases in per barrel margins. Refining & Marketing segment adjusted EBITDA was $4.45 per barrel for the first six months of 2025, versus $7.72 per barrel for the first six months of 2024.
Refining & Marketing margin was $15.57 per barrel for the first six months of 2025 compared to $18.38 per barrel for the first six months of 2024. Refining & Marketing margin is affected by the market indicators shown earlier, which use spot market values and an estimated mix of crude purchases and product sales. Based on the market indicators and our crude oil throughput, we estimate a net negative impact of approximately $2 billion on Refining & Marketing margin for the first six months of 2025 compared to the first six months of 2024, primarily due to lower crack spreads and narrower sour and sweet crude oil differentials. Our reported Refining & Marketing margin differs from market indicators due to the mix of crudes purchased and their costs, market structure on our crude oil acquisition prices, RIN prices on the crack spread, and other items like refinery yields, other feedstock variances and fuel margin from sales to direct dealers. These factors had an estimated net positive effect of approximately $1 billion on Refining & Marketing segment income in the first six months of 2025 compared to the first six months of 2024.
For the six months ended June 30, 2025, refining operating costs, excluding depreciation and amortization, increased $130 million, or $0.08 per barrel, largely due to higher energy costs, partially offset by decreased maintenance costs and expenses for projects conducted during turnaround activity.
Distribution costs, excluding depreciation and amortization, increased $106 million for the first six months of 2025, or $0.04 per barrel, and include fees paid to MPLX of $1.99 billion and $1.96 billion for the first six months of 2025 and 2024, respectively.
Other income decreased $174 million, or $0.34 per barrel, largely due to the absence of insurance proceeds received in the first six months of 2024.
37
Refining planned turnaround costs decreased $125 million, or $0.28 per barrel, due to the scope and timing of turnaround activity.
We purchase RINs to satisfy a portion of our RFS2 compliance. Our expenses associated with purchased RINs were $668 million and $594 million in the first six months of 2025 and 2024, respectively. The RINs expense is included in Refining & Marketing margin. The increase in the first six months of 2025 was mainly due to increased obligated volumes and higher average RIN prices, partially offset by higher RINs generated and acquired from our Martinez Renewables joint venture.

Second Quarter 2025 Compared to Second Quarter 2024
In the second quarter of 2025, Midstream segment adjusted EBITDA increased $21 million mainly due to increased sales and operating revenues of $103 million primarily driven by higher rates and throughputs, offset by higher operating expenses.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Midstream segment adjusted EBITDA increased $152 million in the first six months of 2025 primarily due to increased sales and operating revenues of $389 million resulting from fee increases, higher throughputs, contributions from recent acquisitions and a $37 million non-recurring benefit associated with a customer agreement, partially offset by higher operating expenses.

The following includes key financial and operating data for the second quarter of 2025 compared to the second quarter of 2024 and the six months ended June 30, 2025 compared to the six months ended June 30, 2024.
(a) Includes intersegment sales to Refining & Marketing.
(b) Includes Dickinson facility production and purchased product from our Martinez Renewables joint venture.

Second Quarter 2025 Compared to Second Quarter 2024
Renewable Diesel segment revenues increased $134 million primarily due to increased sales volume of 205 thousand gallons per day. Renewable Diesel segment adjusted EBITDA increased $8 million largely due to increased Renewable Diesel margin, which was $49 million for the second quarter of 2025 compared to $37 million for the second quarter of 2024. The margin increase was due to higher environmental credits associated with increased production volume, partially offset by lower product margins. In the second quarter of 2024, production capacity was reduced due to an event at the Martinez Renewables facility in 2023 that resulted in lower throughput and impacted margins.
See “Non-GAAP Financial Measure” section for reconciliation of Renewable Diesel margin.
Six Months Ended June 30, 2025 Compared to Six Months Ended June 30, 2024
Renewable Diesel segment revenues increased $243 million mainly due to increased sales volume of 295 thousand gallons per day. Renewable Diesel segment adjusted EBITDA increased $56 million primarily due to increased Renewable Diesel margins. Margins increased from $32 million to $75 million in the first six months of 2025 due to higher environmental credits associated with increased production volume, partially offset by lower product margins. In the first six months of 2024, production capacity was reduced due to an event at the Martinez Renewables facility in 2023 that resulted in lower throughput and impacted margins.

Non-GAAP Financial Measures
Management uses 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:
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 calculations thereof may not be comparable to similarly titled measures reported by other companies.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our consolidated cash and cash equivalents balance was approximately $1.67 billion at June 30, 2025 compared to $3.21 billion at December 31, 2024. Net cash provided by (used in) operating activities, investing activities and financing activities are presented in the following table.

Operating Activities
Net cash provided by operating activities decreased $2.20 billion in the first six months of 2025 compared to the first six months of 2024. The change in net cash provided by operating activities was primarily due to a decrease in operating results and an unfavorable change in working capital of $1.19 billion, when comparing the change in working capital in both periods.
43
For the first six months of 2025, changes in working capital, excluding changes in short-term debt, were a net $1.04 billion use of cash mainly due to the effects of changes in energy commodity prices and volumes at the end of the period. Accounts payable decreased primarily due to decreases in crude oil prices, partially offset by increases in crude oil volumes. Inventories increased largely due to increases in crude oil and refined product inventory volumes. Current receivables decreased primarily due to decreases in crude oil prices, partially offset by increases in crude oil volumes and refined product prices.
For the first six months of 2024, changes in working capital, excluding changes in short-term debt, were a net $152 million source of cash mainly due to the effects of changes in energy commodity prices and volumes at the end of the period. Accounts payable increased primarily due to increases in crude oil prices. Current receivables increased largely due to increases in crude oil and refined product prices, partially offset by a decrease in volumes. Inventories increased primarily due to increases in crude oil and refined product inventory volumes. Additionally, working capital was favorably impacted by changes in income tax receivable and unfavorably impacted by changes in prepaid assets and current liabilities.
Investing Activities
Investing activities were a net $1.90 billion use of cash in the first six months of 2025 compared to a net $807 million use of cash in the first six months of 2024.
•In the first six months of 2024, purchases of short-term investments of $2.93 billion were more than offset by maturities and sales of short-term investments of $3.52 billion and $195 million, respectively, for a net source of cash of $789 million.
•Additions to property, plant and equipment increased $286 million. See the Capital Requirements section for additional information on our capital investment plan.
•Cash used for acquisitions of $237 million and $622 million in the first six months of 2025 and 2024, respectively, were due to acquisitions in our Midstream segment.
•Cash used in net investments was $428 million for the first six months of 2025 compared to $45 million for the first six months of 2024. In the first six months of 2025, investments mainly included contributions to MPLX equity method investments. In the first six months of 2024, investments primarily included a return of capital of $134 million related to the Whistler Joint Venture Transaction more than offset by Midstream equity method investments, including a $92 million contribution made in March 2024 for the repayment of MPLX’s share of the Dakota Access joint venture’s debt due in 2024.
The consolidated statements of cash flows exclude changes to the consolidated balance sheets that did not affect cash. A reconciliation of additions to property, plant and equipment per the consolidated statements of cash flows to reported total capital expenditures and investments follows.

Capital Resources
MPC, Excluding MPLX
We control MPLX through our ownership of the general partner; however, the creditors of MPLX do not have recourse to MPC’s general credit through guarantees or other financial arrangements, except as noted. MPC has effectively guaranteed certain indebtedness of LOOP and LOCAP, in which MPLX holds an interest. Therefore, in the following table, we present the liquidity of MPC, excluding MPLX. MPLX liquidity is discussed in the following section.
Our liquidity, excluding MPLX, totaled $5.18 billion at June 30, 2025 consisting of:
| June 30, 2025 | ||||||||||||||||||||||||||
| (Millions of dollars) | Total Capacity | Outstanding Borrowings | Outstanding Letters of Credit | Available Capacity | ||||||||||||||||||||||
| Bank revolving credit facility | $ | 5,000 | $ | — | $ | 1 | $ | 4,999 | ||||||||||||||||||

Cash and cash equivalents and short-term investments(c) | 287 | |||||||||||||||||||||||||
| Total liquidity | $ | 5,176 | ||||||||||||||||||||||||
(a)The committed borrowing and letter of credit issuance capacity under the trade receivables securitization facility is $100 million. In addition, the facility allows for the issuance of letters of credit in excess of the committed capacity at the discretion of the issuing banks.
(b) We do not intend to have outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit facility.
(c) Excludes cash and cash equivalents of MPLX of $1.39 billion.
We have a commercial paper program that allows us to have a maximum of $2.0 billion in commercial paper outstanding. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under our bank revolving credit facility. At June 30, 2025, we had $210 million in aggregate principal amount of commercial paper outstanding under the commercial paper program.
Because of the alternatives available to us, including internally generated cash flow, revolving credit and trade receivable facilities, access to capital markets and a commercial paper program, we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements, including capital spending programs, the repurchase of shares of our common stock, dividend payments, defined benefit plan contributions, repayment of debt maturities and other amounts that may ultimately be paid in connection with contingencies.
On February 10, 2025, MPC issued $2.0 billion in aggregate principal amount of senior notes in an underwritten public offering, consisting of $1.1 billion aggregate principal amount of 5.150 percent senior notes due March 2030 and $900 million aggregate principal amount of 5.700 percent senior notes due March 2035. The senior notes offering replaced the $750 million aggregate principal amount of 3.625 percent senior notes that matured in September 2024 and was used to repay the $1.250 billion aggregate principal amount of 4.700 percent senior notes at maturity on May 1, 2025.
MPC’s bank revolving credit facility and trade receivables facility contain representations and warranties, affirmative and negative covenants and restrictions, including financial covenants, and events of default that we consider usual and customary for agreements of a similar type and nature. As of June 30, 2025, we were in compliance with such covenants and restrictions.
45
Our intention is to maintain an investment-grade credit profile. As of June 30, 2025, the credit ratings on our senior unsecured debt are as follows.
| Company | Rating Agency | Rating | ||||||
| MPC | Moody’s | Baa2 (stable outlook) | ||||||
| Standard & Poor’s | BBB (stable outlook) | |||||||
| Fitch | BBB (stable outlook) | |||||||
The ratings reflect the respective views of the rating agencies and should not be interpreted as a recommendation to buy, sell or hold our securities. Although it is our intention to maintain a credit profile that supports an investment grade rating, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant. A rating from one rating agency should be evaluated independently of ratings from other rating agencies.
The agreements governing MPC’s debt obligations do not contain credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that our credit ratings are downgraded. However, any downgrades of our senior unsecured debt could increase the applicable interest rates, yields and other fees payable under such agreements and may limit our flexibility to obtain financing in the future, including to refinance existing indebtedness. In addition, a downgrade of our senior unsecured debt rating to below investment-grade levels could, under certain circumstances, impact our ability to purchase crude oil on an unsecured basis and could result in us having to post letters of credit under existing transportation services or other agreements.
See Note 16 to the unaudited consolidated financial statements for further discussion of our debt.
MPLX
MPLX’s liquidity totaled $4.89 billion at June 30, 2025 consisting of:

On February 18, 2025, MPLX repaid all of MPLX's outstanding $500 million aggregate principal amount of 4.000 percent senior notes due February 2025 at maturity.
On March 10, 2025, MPLX issued $2.0 billion in aggregate principal amount of senior notes in an underwritten public offering, consisting of $1.0 billion aggregate principal amount of 5.400 percent senior notes due April 2035 and $1.0 billion aggregate principal amount of 5.950 percent senior notes due April 2055. On April 9, 2025, MPLX used the net proceeds from this offering to redeem all of MPLX LP’s outstanding $1,189 million aggregate principal amount of 4.875 percent senior notes due June 2025 and MarkWest Energy Partners, L.P.’s outstanding $11 million aggregate principal amount of 4.875 percent senior notes due June 2025. MPLX intends to use the remaining net proceeds for general partnership purposes.
On July 3, 2025, MPLX used cash on hand to extinguish approximately $656 million of debt principal outstanding, including interest, related to certain term and revolving loans assumed as part of the BANGL Acquisition. See Note 23 to the unaudited consolidated financial statements for additional information on this transaction.
MPLX intends to use debt financing to restore liquidity after using cash on hand for the recently completed acquisition of the remaining 55 percent of BANGL pipeline system and related debt repayments, and to fund the announced acquisition of Northwind Midstream.
MPLX’s bank revolving credit facility contains certain representations and warranties, affirmative and restrictive covenants and events of default that we consider to be usual and customary for an agreement of this type. As of June 30, 2025, MPLX was in compliance with such covenants.
46
Our intention is to maintain an investment-grade credit profile for MPLX. As of June 30, 2025, the credit ratings on MPLX’s senior unsecured debt are as follows.
| Company | Rating Agency | Rating | ||||||
| MPLX | Moody’s | Baa2 (stable outlook) | ||||||
| Standard & Poor’s | BBB (stable outlook) | |||||||
| Fitch | BBB (stable outlook) | |||||||
The ratings reflect the respective views of the rating agencies and should not be interpreted as a recommendation to buy, sell or hold MPLX securities. Although it is our intention to maintain a credit profile that supports an investment grade rating for MPLX, there is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant. A rating from one rating agency should be evaluated independently of ratings from other rating agencies.
The agreements governing MPLX’s debt obligations do not contain credit rating triggers that would result in the acceleration of interest, principal or other payments in the event that MPLX credit ratings are downgraded. However, any downgrades of MPLX senior unsecured debt to below investment-grade ratings could increase the applicable interest rates, yields and other fees payable under such agreements. In addition, a downgrade of MPLX senior unsecured debt ratings to below investment-grade levels may limit MPLX’s ability to obtain future financing, including to refinance existing indebtedness.
See Note 16 to the unaudited consolidated financial statements for further discussion of MPLX’s debt.
Capital Requirements
Capital Investment Plan
MPC's capital investment outlook for 2025 totals approximately $1.25 billion for capital projects and investments, excluding capitalized interest, potential acquisitions, if any, and MPLX’s capital investment plan. MPC’s capital investment outlook includes all of the planned capital spending for Refining & Marketing, Renewable Diesel and Corporate, as well as a portion of the planned capital investments for Midstream. The remainder of the planned capital spending for Midstream reflects the capital investment plan for MPLX, which totals $2.0 billion, excluding capitalized interest, acquisitions, if any, reimbursable capital and any incremental capital project expenditures associated with the pending Northwind Midstream acquisition. We continuously evaluate our capital investment plan and make changes as conditions warrant.
Capital expenditures and investments for MPC and MPLX are summarized below.

Major Refining & Marketing projects include advancing improvements focused on integrating and modernizing utility systems and increasing energy efficiency, with the added benefit of addressing upcoming regulation mandating further reductions in emissions at our Los Angeles refinery, a multi-year project to upgrade high sulfur distillate to ULSD and maximize distillate volume expansion at our Galveston Bay refinery and a project to increase flexibility and optimize jet production at our Robinson refinery. In addition to these multi-year investments, the company is executing short-duration, high-return projects that are expected to enhance the yields of our refineries, improve energy efficiency and lower our costs as well as investments in our branded marketing footprint.
47
Our Midstream segment capital expenditures and investments in affiliates were primarily for expanding our Permian to Gulf Coast integrated natural gas and NGL value chain, gas processing plants in the Marcellus and Permian basins and gas gathering projects in the Marcellus, Utica and Permian basins.

(b) The average cost per share includes excise tax on share repurchases resulting from the Inflation Reduction Act of 2022, but the excise tax does not reduce the remaining share repurchase authorization.
From January 1, 2012 through June 30, 2025, our board of directors had approved $60.05 billion in total share repurchase authorizations and we repurchased a total of $54.02 billion of our common stock. As of June 30, 2025, $6.03 billion remained available for repurchase under the share repurchase authorizations.
We 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 and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be suspended, discontinued or restarted at any time.

Contractual Obligations
As of June 30, 2025, our purchase commitments primarily consist of obligations to purchase and transport crude oil used in our refining operations. Additionally, in July 2025, MPLX completed the BANGL Acquisition and entered into an agreement to acquire Northwind Midstream as described in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Strategic Updates. During the first six months of 2025, there were no other material changes to our contractual obligations outside the ordinary course of business since December 31, 2024.
Our other contractual obligations primarily consist of long-term debt and pension and post-retirement obligations, for which additional information is included in Notes 16 and 21, respectively, to the unaudited consolidated financial statements, and financing and operating leases.
48
Other Cash Commitments
On July 30, 2025, our board of directors declared a dividend of $0.91 per share on common stock. The dividend is payable September 10, 2025 to shareholders of record as of the close of business on August 20, 2025.
During the six months ended June 30, 2025, we made contributions of $36 million to our funded pension plans and plan to make an additional required contribution of approximately $135 million in the third quarter of 2025. We may make additional voluntary contributions at our discretion depending on the anticipated funding status and plan asset performance.
We may, from time to time, repurchase our senior notes in the open market, in tender offers, in privately-negotiated transactions or otherwise in such volumes, at such prices and upon such other terms as we deem appropriate.
ENVIRONMENTAL MATTERS AND COMPLIANCE COSTS
We have incurred and may continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations. If these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected. We believe that substantially all of our competitors must comply with similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including the age and location of its operating facilities, marketing areas, production processes and whether it is also engaged in the petrochemical business or the marine transportation of crude oil and refined products.
As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024, actual expenditures may vary as the number and scope of environmental projects are revised as a result of improved technology or changes in regulatory requirements.
There have been no additional significant changes to our environmental matters and compliance costs during the six months ended June 30, 2025.
CRITICAL ACCOUNTING ESTIMATES
As of June 30, 2025, there have been no significant changes to our critical accounting estimates since our Annual Report on Form 10-K for the year ended December 31, 2024.
ACCOUNTING STANDARDS NOT YET ADOPTED
As discussed in Note 2 to the unaudited consolidated financial statements, certain new financial accounting pronouncements will be effective for our financial statements in the future.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
For a detailed discussion of our risk management strategies and our derivative instruments, see Item 7A. Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2024.
See Notes 14 and 15 to the unaudited consolidated financial statements for more information about the fair value measurement of our derivatives, as well as the amounts recorded in our consolidated balance sheets and statements of income. We do not designate any of our commodity derivative instruments as hedges for accounting purposes.
The following table includes the composition of net losses on our commodity derivative positions as of June 30, 2025 and 2024, respectively.
| Six Months Ended June 30, | ||||||||||||||
| (Millions of dollars) | 2025 | 2024 | ||||||||||||

See Note 15 to the unaudited consolidated financial statements for additional information on our open derivative positions at June 30, 2025.
Sensitivity analysis of the effects on income from operations (“IFO”) of hypothetical 10 percent and 25 percent increases and
49
decreases in commodity prices for open commodity derivative instruments as of June 30, 2025 is provided in the following table.
| Change in IFO from a Hypothetical Price Increase of | Change in IFO from a Hypothetical Price Decrease of | |||||||||||||||||||||||||
| (Millions of dollars) | 10% | 25% | 10% | 25% | ||||||||||||||||||||||

| Blending products | (7) | (16) | 7 | 16 | ||||||||||||||||||||||
| Soybean oil | (10) | (25) | 10 | 25 | ||||||||||||||||||||||
We remain at risk for possible changes in the market value of commodity derivative instruments; however, such risk should be mitigated by price changes in the underlying physical commodity. Effects of these offsets are not reflected in the above sensitivity analysis.
We evaluate our portfolio of commodity derivative instruments on an ongoing basis and add or revise strategies in anticipation of changes in market conditions and in risk profiles. Changes to the portfolio after June 30, 2025 would cause future IFO effects to differ from those presented above.
Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on long-term debt, including the portion classified as current and excluding finance leases, as of June 30, 2025 is provided in the following table. The fair value of cash and cash equivalents, receivables, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.
| (Millions of dollars) | Fair Value as of June 30, 2025(a) | Change in Fair Value(b) | Change in Net Income for the Six Months Ended June 30, 2025(c) | |||||||||||||||||
| Long-term debt | ||||||||||||||||||||
| Fixed-rate | $ | 26,355 | $ | 2,150 | n/a | |||||||||||||||
| Variable-rate | $ | 210 | $ | — | $ | — | ||||||||||||||
(a)Fair value was based on market prices, where available, or current borrowing rates for financings with similar terms and maturities.
(b)Assumes a 100-basis-point decrease in the weighted average yield-to-maturity at June 30, 2025.
(c)Assumes a 100-basis-point change in interest rates. The change to net income was based on the weighted average balance of debt outstanding for the six months ended June 30, 2025.
At June 30, 2025, our long-term debt was composed of fixed-rate instruments and variable-rate borrowings. The fair value of our fixed-rate debt is relatively sensitive to interest rate fluctuations. Our sensitivity to interest rate declines and corresponding increases in the fair value of our debt unfavorably affects our results of operations and cash flows only when we elect to repurchase or otherwise retire fixed-rate debt at prices above carrying value. Interest rate fluctuations generally do not impact the fair value of our variable-rate debt, but may affect our results of operations and cash flows.
See Note 14 to the unaudited consolidated financial statements for additional information on the fair value of our debt.
Item 4. Controls and Procedures
Disclosure Controls and Procedures
An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), was carried out under the supervision and with the participation of our management, including our chief executive officer and chief financial officer. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the design and operation of these disclosure controls and procedures were effective as of June 30, 2025, the end of the period covered by this Quarterly Report on Form 10-Q.
Changes in Internal Control over Financial Reporting
During the quarter ended June 30, 2025, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION
Item 1. Legal Proceedings
We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. While it is possible that an adverse result in one or more of the lawsuits or proceedings in which we are a defendant could be material to us, based upon current information and our experience as a defendant in other matters, we believe that these lawsuits and proceedings, individually or in the aggregate, will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.
Item 103 of Regulation S-K promulgated by the SEC requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions, unless we reasonably believe that the matter will result in no monetary sanctions, or in monetary sanctions, exclusive of interest and costs, of less than a specified threshold of $1 million for this purpose.
Except as described below, there have been no material changes to the legal matters previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024.
On August 4, 2025, the Washington Department of Ecology (“Washington DOE”) commenced an enforcement action against Tesoro Refining & Marketing Company LLC, a subsidiary of the Company, for allegedly violating provisions of the Washington Hazardous Waste Management Act and associated regulations. The Washington DOE seeks a penalty in excess of $1 million. We cannot currently estimate the timing of the resolution of this matter but do not believe any civil penalty will have a material impact on our consolidated results of operations, financial position or cash flows.
Item 1A. Risk Factors
There have been no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The weighted average price includes any commissions paid to brokers during the relevant period. The weighted average price does not include any excise tax incurred on the share repurchases.
(b)On April 30, 2024, we announced that our board of directors had approved a $5.0 billion share repurchase authorization. On November 5, 2024, we announced that our board of directors had approved an additional $5.0 billion share repurchases authorization. These share repurchase authorizations have no expiration date.
(c)The maximum dollar value remaining has been reduced by the amount of any commissions paid to brokers. The maximum dollar value remaining has not been reduced by the amount of any excise tax incurred on the share repurchases.
Item 5. Other Information
On May 14, 2025 , Molly R. Benson , Chief Legal Officer and Corporate Secretary of the Company , adopted a trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act providing for the potential sale of 10,879 shares of our common stock between August 14, 2025 and August 14, 2026 .

As previously announced, Timothy J. Aydt ceased service as our Executive Vice President, Refining, on June 1, 2025, and has continued service with the company in a non-executive officer role since that time. Mr. Aydt’s official retirement will take place on September 2, 2025. On August 4, 2025, we entered into a Consulting Agreement with Mr. Aydt, to be effective following his retirement on September 2, 2025. Under the agreement, Mr. Aydt will continue to support the transition of his executive role and related activities. He is expected to work as an independent contractor until December 31, 2025, and will receive monthly consulting fees equal to $170,000 and reasonable expense reimbursement for his services. Under the agreement, Mr. Aydt will be subject to customary restrictive and other covenants during and after his consulting service.
