MPLX LP Q2 2025 (10-Q) Highlights: Der Gesamtumsatz und andere Einnahmen sanken im Jahresvergleich um 1,6 % auf 3,0 Mrd. USD, w盲hrend die Kosten um 4,7 % stiegen, was zu einem R眉ckgang des operativen Ergebnisses um 8,9 % auf 1,29 Mrd. USD f眉hrte. Der auf MPLX entfallende Nettogewinn fiel um 10,9 % auf 1,05 Mrd. USD (1,03 USD pro Einheit). F眉r das erste Halbjahr blieb der Nettogewinn mit 2,17 Mrd. USD stabil, und das verw盲sserte Ergebnis je Aktie lag bei 2,13 USD.
Barmittel & Kapital: Der operative Cashflow stieg um 4 % auf 2,98 Mrd. USD und finanzierte problemlos 609 Mio. USD Capex, 1,95 Mrd. USD Aussch眉ttungen an Anteilseigner und 200 Mio. USD Aktienr眉ckk盲ufe. Die Barreserve betr盲gt 1,39 Mrd. USD; keine revolvierenden Kredite. Die langfristigen Schulden stiegen auf 19,7 Mrd. USD nach der Emission von 2 Mrd. USD Anleihen mit Zinss盲tzen von 5,40 % bis 5,95 % und der R眉ckzahlung von 1,2 Mrd. USD 4,875 %-Anleihen mit F盲lligkeit 2025; Verschuldungsgrad ca. 3,3脳 des annualisierten bereinigten EBITDA.
Wachstum & Portfolio-Entwicklungen: Erwerb weiterer 5 % der Matterhorn Express-Pipeline f眉r 151 Mio. USD (insgesamt 10 %), Abschluss der 脺bernahme von Whiptail Midstream f眉r 237 Mio. USD und Investition von 322 Mio. USD in Gas/NGL-Joint Ventures. Das segmentbezogene bereinigte EBITDA stieg um 2 % auf 1,69 Mrd. USD (Rohstofflogistik 1,14 Mrd.; Erdgas/NGL 0,55 Mrd.).

Wichtige Beobachtungspunkte: Margendruck, steigende Zinsaufwendungen (488 Mio. USD im Jahresverlauf), rechtliche Risiken im Zusammenhang mit einer m枚glichen Stilllegung von Dakota Access sowie die Auswirkungen wachstumsfinanzierter Verschuldung auf den Verschuldungsgrad. Der vertraglich gesicherte Mindestvolumen-Backlog betr盲gt 6,4 Mrd. USD und sichert langfristige Cashflows ab.
Positive
- Operating cash flow rose 4 % YoY to $2.98 bn, covering distributions, capex and buy-backs with excess liquidity.
- Quarterly distribution increased 13 % to $0.9565/unit and remains 1.5脳 covered by cash flow.
- Refinanced 2025 maturities with longer-dated 2035/2055 notes, reducing near-term debt wall.
- Strategic acquisitions (Matterhorn stake, Whiptail assets) expand high-growth gas infrastructure footprint.
Negative
- Q2 net income and EPS declined roughly 11 % YoY due to higher costs and lower equity income.
- Total debt climbed to $21.5 bn; interest expense up 5 % YoY, raising leverage concerns.
- Margin compression: costs and expenses grew 4.7 % while revenue fell, pressuring operating income.
- Legal uncertainty around Dakota Access pipeline could trigger contingent equity contributions and disrupt cash flows.
Insights
TL;DR: Solid cash generation funds growth & payouts, but YoY earnings dip and higher leverage temper enthusiasm.
Revenue was essentially flat, yet cost inflation and lower equity-method contributions cut net income by 11 %. Importantly, FFO rose as working-capital swung positive, giving a 1.5脳 distribution coverage and headroom for $200 m buy-backs. The capital mix skews debt-heavy: 2025 note refinancing extends duration but pushes gross debt to $21.4 bn and interest cost up 5 %. Leverage remains manageable around 3.3脳, but further acquisitions could strain metrics in a higher-rate world. Incremental stakes in Matterhorn and Whiptail expand Permian & San Juan exposure and should be EBITDA-accretive once integrated. Distribution growth (13 %) signals confidence, yet investors should monitor margin recovery and Dakota Access litigation, which could require cash injections.
TL;DR: Distribution secure; coverage durable, but earnings downtrend warrants caution.
MPLX again demonstrates the MLP model鈥檚 cash-flow resilience: 6-month OCF of $3 bn covers all capex and payouts with ~$800 m to spare. Conversion of preferreds simplifies equity and removes the 8-% coupon drag. However, Q2 EBITDA margin compressed 190 bps and unit repurchases at ~$51/unit add marginal accretion amid softer EPS. New 5.4-5.95 % notes price above the partnership鈥檚 historical average, moving weighted cost of debt higher. Contract backlog of $6.4 bn plus MPC throughput minimums provide visibility, yet investors must weigh regulatory overhang on Bakken and $609 m YTD growth capex versus modest EBITDA growth. Net impact: neutral.

1. Description of the Business and Basis of Presentation
Description of the Business
MPLX LP is a diversified, large-cap master limited partnership formed by Marathon Petroleum Corporation that owns and operates midstream energy infrastructure and logistics assets, and provides fuels distribution services. We are engaged in the gathering, transportation, storage and distribution of crude oil, refined products, other hydrocarbon-based products and renewables; the gathering, processing and transportation of natural gas; and the transportation, fractionation, storage and marketing of NGLs. MPLX’s principal executive office is located in Findlay, Ohio. MPLX was formed on March 27, 2012 as a Delaware limited partnership.
MPLX’s business consists of two segments based upon the product-based value chain each supports. The Crude Oil and Products Logistics segment includes the gathering, transportation, storage and distribution of crude oil, refined products, other hydrocarbon-based products and renewables. The Natural Gas and NGL Services segment gathers, processes and transports natural gas and transports, fractionates, stores and markets NGLs. See Note 8 for additional information regarding the operations and results of these segments.
Basis of Presentation
These interim consolidated financial statements are unaudited; however, in the opinion of MPLX’s 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 and regulations 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 derived from our audited annual financial statements, prepared in accordance with GAAP, has 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.
MPLX’s consolidated financial statements include all majority-owned and controlled subsidiaries. For non-wholly-owned consolidated subsidiaries, the interests owned by third parties have been recorded as Noncontrolling interests on the accompanying Consolidated Balance Sheets. Intercompany accounts and transactions have been eliminated. MPLX’s investments in which MPLX exercises significant influence but does not control and does not have a controlling financial interest are accounted for using the equity method. MPLX’s investments in VIEs, in which MPLX exercises significant influence but does not control and is not the primary beneficiary, are also accounted for using the equity method.
In the fourth quarter of 2024, we renamed and modified the composition of our segments to better reflect the product-based value chains and growth strategy of MPLX’s operations. Certain prior period financial statement amounts have been reclassified to conform to current period presentation.
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.

3. Acquisitions and Other Transactions
Matterhorn Express Pipeline Acquisition
On June 16, 2025, MPLX purchased an additional five percent ownership interest in the joint venture that owns and operates the Matterhorn Express pipeline for $151 million, bringing our total interest to 10 percent. The pipeline is designed to transport natural gas from the Permian basin to the Katy area near Houston. The purchase price of the additional five percent ownership interest in the joint venture exceeded the amount of the claim to the underlying net assets of the joint venture by approximately $124 million, with $63 million of this difference attributed to property, plant and equipment and $61 million attributed to customer-related intangibles. The amounts attributed to property, plant and equipment and customer-related intangibles will be amortized to net income over the remaining useful lives of the assets and the weighted-average remaining term of the customer contracts, respectively. Our investment in the joint venture that owns and operates the Matterhorn Express pipeline continues to be accounted for as an equity method investment within our Natural Gas and NGL Services segment.
Whiptail Midstream Acquisition
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 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
The Utica Midstream 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 Other income within the accompanying consolidated statements of income. The fair value of equity method investments was based on a discounted cash flow model.

(1) The investment in MarEn Bakken Company LLC includes our 9.19 percent indirect interest in a joint venture (“Dakota Access”) that owns and operates the Dakota Access Pipeline and Energy Transfer Crude Oil Pipeline projects (collectively, the “Bakken Pipeline system”).
(2) Some investments included within Other have also been deemed to be VIEs.
(3) On March 31, 2025, MPLX contributed a 100 percent owned subsidiary with a fair value of $125 million to MarkWest EMG Jefferson Dry Gas Gathering Company, L.L.C. MPLX received a special distribution of $21 million as a result of the transaction, which is reflected as a return of capital on the consolidated statement of cash flows.
(4) MPLX also holds a 40 percent indirect interest in OGC through our ownership interest in MarkWest Utica EMG, L.L.C.
For those entities that have been deemed to be VIEs, neither MPLX nor any of its subsidiaries have been deemed to be the primary beneficiary due to voting rights on significant matters. While we have the ability to exercise influence through participation in the management committees, which make all significant decisions, we have equal influence over each committee as a joint interest partner and all significant decisions require the consent of the other investors without regard to economic interest. As such, we have determined that these entities should not be consolidated and applied the equity method of accounting with respect to our investments in each entity.
MPLX’s maximum exposure to loss as a result of its involvement with equity method investments generally includes its equity investment, any additional capital contribution commitments and any operating expenses incurred by the subsidiary operator in excess of its compensation received for the performance of the operating services. MPLX did not provide any financial support to equity method investments that it was not contractually obligated to provide during the six months ended June 30, 2025 and June 30, 2024. See Note 16 for information on our guarantees related to equity method investees.
5. Related Party Agreements and Transactions
MPLX engages in transactions with both MPC and certain of its equity method investments as part of its normal business; however, transactions with MPC make up the majority of MPLX’s related party transactions. Transactions with related parties are further described below.
MPLX has various long-term, fee-based commercial agreements with MPC. Under these agreements, MPLX provides transportation, gathering, terminal, fuels distribution, marketing, storage, management, operational and other services to MPC. MPC has committed to provide MPLX with minimum quarterly throughput volumes on crude oil and refined products and other fees for storage capacity; operating and management fees; and reimbursements for certain direct and indirect costs. MPC has also committed to provide a fixed fee for 100 percent of available capacity for boats, barges and third-party chartered equipment under the marine transportation service agreements. In addition, MPLX has obligations to MPC for services provided to MPLX by MPC under omnibus and employee services type agreements as well as various other agreements. MPLX also had a keep-whole commodity agreement with MPC under which MPC paid us a processing fee for NGLs related to keep-whole agreements and we paid MPC a marketing fee in exchange for assuming the commodity risk. This agreement expired in March 2025.
10
Related Party Loan
MPLX is party to a loan agreement (the “MPC Loan Agreement”) with MPC. Under the terms of the MPC Loan Agreement, MPC extends loans to MPLX on a revolving basis as requested by MPLX and as agreed to by MPC. The borrowing capacity of the MPC Loan Agreement is $1.5 billion aggregate principal amount of all loans outstanding at any one time. The MPC Loan Agreement is scheduled to expire, and borrowings under the loan agreement are scheduled to mature and become due and payable, on July 31, 2029, provided that MPC may demand payment of all or any portion of the outstanding principal amount of the loan, together with all accrued and unpaid interest and other amounts (if any), at any time prior to maturity. Borrowings under the MPC Loan Agreement bear interest at one-month term SOFR adjusted upward by 0.10 percent plus 1.25 percent or such lower rate as would be applicable to such loans under the MPLX Credit Agreement as discussed in Note 12.
There was no activity on the MPC Loan Agreement for the six months ended June 30, 2025 and June 30, 2024.
Related Party Revenue and Other Income
Related party revenue consists primarily of revenue recognized from commercial agreements with MPC as well as fees charged under operating agreements with MPC and our equity affiliates as discussed above.
Certain product sales to MPC and other related parties net to zero within the consolidated financial statements as the transactions are recorded net due to the terms of the agreements under which such product was sold. For the three and six months ended June 30, 2025, these sales totaled $140 million and $325 million, respectively. For the three and six months ended June 30, 2024, these sales totaled $182 million and $384 million, respectively.
Related Party Expenses
MPC charges MPLX for executive management services and certain general and administrative services provided to MPLX under the terms of our omnibus agreements (“Omnibus charges”), for certain employee services provided to MPLX under employee services agreements (“ESA charges”) and fees paid under co-location agreements and ground lease agreements. Omnibus charges and ESA charges are classified as Rental cost of sales - related parties, Purchases - related parties, or General and administrative expenses depending on the nature of the asset or activity with which the costs are associated. Additionally, we also incur costs under agreements for transportation and processing services with certain of our unconsolidated affiliates.
In addition to these agreements, MPLX purchases products from MPC, makes payments to MPC in its capacity as general contractor to MPLX, and has certain rent and lease agreements with MPC.
For the three and six months ended June 30, 2025, General and administrative expenses incurred from MPC totaled $81 million and $156 million, respectively. For the three and six months ended June 30, 2024, General and administrative expenses incurred from MPC totaled $71 million and $144 million, respectively.
Some charges incurred under the omnibus and employee service agreements are related to engineering services and are associated with assets under construction. These charges are added to Property, plant and equipment, net on the Consolidated Balance Sheets. For the three and six months ended June 30, 2025, these charges totaled $46 million and $95 million, respectively. For the three and six months ended June 30, 2024, these charges totaled $39 million and $80 million, respectively.

Unit Repurchase Program
On August 2, 2022, we announced a board authorization for the repurchase of up to $1.0 billion of MPLX common units held by the public. This unit repurchase authorization has no expiration date. We 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.

As of June 30, 2025, we had $320 million remaining under the unit repurchase authorization.
Series A Redeemable Preferred Unit Conversions
On February 11, 2025, MPLX exercised its right to convert the remaining 6 million outstanding Series A preferred units into common units in accordance with the conversion provision outlined in our Sixth Amended and Restated Agreement of Limited Partnership.
Distributions
On July 29, 2025 , MPLX declared a cash distribution for the second quarter of 2025, totaling $975 million, or $0.9565 per common unit. This distribution will be paid on August 15, 2025 to common unitholders of record on August 8, 2025 .
Quarterly distributions for 2025 and 2024 are summarized below:

7. Net Income Per Limited Partner Unit
Net income per unit applicable to common units is computed by dividing net income attributable to MPLX LP less income allocated to participating securities by the weighted average number of common units outstanding.
During the three and six months ended June 30, 2025 and June 30, 2024, MPLX had participating securities consisting of common units, certain equity-based compensation awards, Series A preferred units, and also had dilutive potential common units consisting of certain equity-based compensation awards. Potential common units that were anti-dilutive, and therefore omitted from the diluted earnings per unit calculation for the three and six months ended June 30, 2025 and June 30, 2024 were less than one million

8. Segment Information
MPLX’s chief operating decision maker (“CODM”) is the chief executive officer of its general partner. The CODM reviews MPLX’s discrete financial information, makes operating decisions, assesses financial performance and allocates resources on a product-based value chain basis. MPLX has two reportable segments: Crude Oil and Products Logistics and Natural Gas and NGL Services. Each of these segments is organized and managed based upon the product-based value chain each supports.
•Crude Oil and Products Logistics – gathers, transports, stores and distributes crude oil, refined products, other hydrocarbon-based products and renewables. Also includes the operation of refining logistics, fuels distribution and inland marine businesses, terminals, rail facilities, and storage caverns.
•Natural Gas and NGL Services – gathers, processes and transports natural gas; and transports, fractionates, stores and markets NGLs.
The CODM evaluates the performance of our segments using Segment Adjusted EBITDA. The CODM uses Segment Adjusted EBITDA results when making decisions about allocating capital and personnel as a part of the annual business plan process and ongoing monitoring of performance. Amounts included in net income and excluded from Segment Adjusted EBITDA include: (i) depreciation and amortization; (ii) net interest and other financial costs; (iii) income/(loss) from equity method investments; (iv) distributions and adjustments related to equity method investments; (v) impairment expense; (vi) noncontrolling interests; and (vii) other adjustments, as applicable. 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) are not tied to the operational performance of the segment. Assets by segment are not a measure used to assess the performance of the Partnership by our CODM and thus are not reported in our disclosures.

10. Fair Value Measurements
Fair Values – Recurring
The following table presents the impact on the Consolidated Balance Sheets of MPLX’s financial instruments carried at fair value on a recurring basis as of June 30, 2025 and December 31, 2024 by fair value hierarchy level.

| Total carrying value in Consolidated Balance Sheets | $ | $ | $ | $ | |||||||||||||||||||
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 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 renewal term of the 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, respectively.

(1) Gain/(loss) on derivatives embedded in commodity contracts are recorded in in the Consolidated Statements of Income.
Fair Values – Non-recurring
Non-recurring fair value measurements and disclosures for the six months ended June 30, 2025 and June 30, 2024 relate to acquisitions and other transactions as discussed in Note 3.
Fair Values – Reported
We believe the carrying value of our other financial instruments, including cash and cash equivalents, receivables, receivables from related parties, lease receivables, lease receivables from related parties, accounts payable, and payables to related parties, approximate fair value. MPLX’s fair value assessment incorporates a variety of considerations, including the duration of the instruments, MPC’s investment-grade credit rating, and the historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. The recorded value of the amounts outstanding under the bank revolving credit facility, if any, approximates fair value due to the variable interest rate that approximates current market rates. Derivative instruments are recorded at fair value, based on available market information (see Note 11).
The fair value of MPLX’s debt is estimated based on prices from recent trade activity and is categorized in Level 3 of the fair value hierarchy. The following table summarizes the fair value and carrying value of our third-party debt, excluding finance leases and unamortized debt issuance costs:
| June 30, 2025 | December 31, 2024 | ||||||||||||||||||||||

Outstanding debt(1) | $ | $ | $ | $ | |||||||||||||||||||
(1) Any amounts outstanding under the MPC Loan Agreement are not included in the table above, as the carrying value approximates fair value. This balance is reflected in Current liabilities - related parties in the Consolidated Balance Sheets.
11. Derivatives
Embedded Derivative - MPLX has a natural gas purchase commitment embedded in a keep-whole processing agreement with a producer customer in the Southern Appalachia region expiring in December 2027. The customer has the unilateral option to extend the agreement for one -year term through December 2032. For accounting purposes, the natural gas purchase commitment and the term extending option have been aggregated into a single compound embedded derivative. The probability of the customer exercising its option is determined based on assumptions about the customer’s potential business strategy decision points that may exist at the time they would elect whether to renew the contract. The changes in fair value of this compound embedded derivative are based on the difference between the contractual and index pricing, the probability of the producer customer exercising its option to extend, and the estimated favorability of these contracts compared to current market conditions. The changes in fair value are recorded in earnings through Purchased product costs in the Consolidated Statements of Income. For further information regarding the fair value measurement of derivative instruments, see Note 10. As of June 30, 2025 and December 31, 2024, the estimated fair value of this contract was a liability of $55 million and $58 million, respectively.
Certain derivative positions are subject to master netting agreements; therefore, MPLX has elected to offset derivative assets and liabilities that are legally permissible to be offset. As of June 30, 2025 and December 31, 2024, there were no derivative assets or liabilities that were offset in the Consolidated Balance Sheets.

We make a distinction between realized or unrealized gains and losses on derivatives. During the period when a derivative contract is outstanding, changes in the fair value of the derivative are recorded as an unrealized gain or loss. When a derivative contract matures or is settled, the previously recorded unrealized gain or loss is reversed, and the realized gain or loss of the contract is recorded. The impact of MPLX’s derivative contracts not designated as hedging instruments and the location of gains and losses recognized in the Consolidated Statements of Income is summarized below:

Credit Agreement
MPLX’s credit agreement (the “MPLX Credit Agreement”) matures in July 2027 and, among other things, provides for a $2.0 billion unsecured revolving credit facility and letter of credit issuing capacity under the facility of up to $150 million. Letter of credit issuing capacity is included in, not in addition to, the $2.0 billion borrowing capacity. Borrowings under the MPLX Credit Agreement bear interest, at MPLX’s election, at either the Adjusted Term SOFR or the Alternate Base Rate, both as defined in the MPLX Credit Agreement, plus an applicable margin.
At June 30, 2025, MPLX had no outstanding borrowings and less than $1 million in letters of credit outstanding under the MPLX Credit Agreement, resulting in total availability of approximately $2.0 billion.
Fixed Rate Senior Notes
MPLX’s senior notes, including those issued by consolidated subsidiaries, consist of various series of senior notes maturing between 2026 and 2058 with interest rates ranging from 1.750 percent to 5.950 percent. Interest on each series of notes is payable semi-annually in arrears on various dates depending on the series of the notes.
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 1.0 billion aggregate principal amount of 5.400 percent senior notes due 2035 (the “2035 Senior Notes”) and $1.0 billion aggregate principal amount of 5.950 percent senior notes due 2055 (the “2055 Senior Notes”) in an underwritten public offering. The 2035 Senior Notes and 2055 Senior Notes were offered at prices to the public of 99.398 percent of par and 98.331 percent of par, respectively, each with interest payable semi-annually in arrears, commencing on October 1, 2025. On April 9, 2025, MPLX used $1.2 billion of the net proceeds from the issuance of the 2035 Senior Notes and 2055 Senior Notes to redeem all of (i) MPLX’s outstanding $1,189 million aggregate principal amount of 4.875 percent senior
18
notes due June 2025 and (ii) MarkWest’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.

Contract Balances
Our receivables are primarily associated with customer contracts. Payment terms vary by product or service type; however, the period between invoicing and payment is not significant. Included within the receivables are balances related to commodity sales on behalf of our producer customers, for which we remit the net sales price back to the producer customers upon completion of the sale.
Under certain of our contracts, we recognize revenues in excess of billings which we present as contract assets. Contract assets typically relate to deficiency payments related to minimum volume commitments and aid in construction agreements where the revenue recognized and MPLX’s rights to consideration for work completed exceeds the amount billed to the customer. Contract assets are included in Other current assets and Other noncurrent assets on the Consolidated Balance Sheets.
Under certain of our contracts, we receive payments in advance of satisfying our performance obligations, which are recorded as contract liabilities. Contract liabilities, which are presented as Deferred revenue and Long-term deferred revenue, typically relate to advance payments for aid in construction agreements and deferred customer credits associated with makeup rights and minimum volume commitments. Related to minimum volume commitments, breakage is estimated and recognized into service revenue in instances where it is probable the customer will not use the credit in future periods. We classify contract liabilities as current or long-term based on the timing of when we expect to recognize revenue.

Remaining Performance Obligations
The table below includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) as of June 30, 2025. The amounts presented below are generally limited to fixed consideration from contracts with customers that contain minimum volume commitments.
A significant portion of our future contracted revenue is excluded from the amounts presented below in accordance with ASC 606. Variable consideration that is constrained or not required to be estimated as it reflects our efforts to perform is excluded from this disclosure. Additionally, we do not disclose information on the future performance obligations for any contract with an original expected duration of one year or less, or that are terminable by our customer with little or no termination penalties. Potential future performance obligations related to renewals that have not yet been exercised or are not certain of exercise are excluded from the amounts presented below. Revenues classified as Rental income and Sales-type lease revenue are also excluded from this table.

As of June 30, 2025, unsatisfied performance obligations included in the Consolidated Balance Sheets are $477 million and will be recognized as revenue as the obligations are satisfied, which is generally expected to occur over the next 19 years. A portion of this amount is not disclosed in the table above as it is deemed variable consideration due to volume variability.

16. Commitments and Contingencies
MPLX is 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 MPLX has not recorded a liability, MPLX is 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
MPLX is subject to federal, state and local 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. Penalties may be imposed for non-compliance.
Accrued liabilities for remediation totaled $ at both June 30, 2025 and December 31, 2024. 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.
MPLX is involved in environmental enforcement matters arising in the ordinary course of business. While the outcome and impact to MPLX cannot be predicted with certainty, management believes the resolution of these environmental matters will not, individually or collectively, have a material adverse effect on its 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,
22
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.
MPLX is 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 MPLX cannot be predicted with certainty, management believes the resolution of these other lawsuits and proceedings will not, individually or collectively, have a material adverse effect on its consolidated financial position, results of operations or cash flows.
Guarantees related to indebtedness of equity method investees
Dakota Access
We hold a 9.19 percent indirect interest in Dakota Access, which owns and operates the Bakken Pipeline system. In 2020, the U.S. District Court for the District of Columbia (the “D.D.C.”) ordered the United States 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.
We have entered into a Contingent Equity Contribution Agreement whereby MPLX LP, 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 of the pipeline, MPLX would have to contribute its 9.19 percent pro rata share of the cost to redeem the bonds (including the one 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.
BANGL, LLC
As of June 30, 2025, MPLX’s maximum exposure to loss for BANGL, LLC (“BANGL”) included a $40 million payment guaranty of an unsecured bank term loan for which BANGL was the borrower and obligor. 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.
Other guarantees
MPLX’s maximum exposure to loss for WPC Parent, LLC includes an $82 million 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.
Contractual Commitments and Contingencies
From time to time and in the ordinary course of business, MPLX and its affiliates provide guarantees of MPLX’s subsidiaries’ payment and performance obligations in the Natural Gas and NGL Services segment. Certain natural gas processing and gathering arrangements require MPLX to construct new natural gas processing plants, natural gas gathering pipelines and NGL pipelines and contain certain fees and charges if specified construction milestones are not achieved for reasons other than force majeure. In certain cases, certain producers may have the right to cancel the processing arrangements if there are significant delays that are not due to force majeure. As of June 30, 2025, management does not believe there are any indications that MPLX will not be able to meet the construction milestones, that force majeure does not apply or that such fees and charges will otherwise be triggered.

17. 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, we now own 100 percent of BANGL and its results will be reflected in the Natural Gas and NGL Services 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.
Additional $1.0 Billion Unit Repurchase Authorization
On August 5, 2025, we announced that our board of directors approved an incremental $1.0 billion common unit repurchase authorization. The authorization has no expiration date. We 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.

MPLX Overview
We are a diversified, large-cap master limited partnership formed by MPC in 2012 that owns and operates midstream energy infrastructure and logistics assets, and provides fuels distribution services. The business consists of two segments based on the product-based value chain each supports: Crude Oil and Products Logistics and Natural Gas and NGL Services.
Our Crude Oil and Products Logistics segment gathers, transports, stores and distributes crude oil, refined products, including renewable diesel, and other hydrocarbon-based products. Additionally, the segment markets refined products. The profitability of pipeline transportation operations primarily depends on tariff rates and the volumes shipped through the pipelines. The profitability of marine operations primarily depends on the quantity and availability of our vessels and barges. The profitability of our terminal operations primarily depends on the throughput volumes at our 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
26
on our pipelines and marine vessels, the throughput at our terminals and refining logistics assets serve MPC and our fuels distribution services are used solely by MPC. We have various long-term, fee-based commercial agreements related to services provided to MPC. Under these agreements, we receive 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 Natural Gas and NGL Services segment 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. Natural Gas and NGL Services segment profitability is affected by prevailing commodity prices primarily as a result of processing 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.

Other Highlights
•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 satisfaction or waiver of customary closing conditions, including regulatory approval.
•Returned $1,076 million and $2,154 million of capital to unitholders in the three and six months ended June 30, 2025, via distributions and unit repurchases.
•Announced a second quarter 2025 distribution of $0.9565 per common unit.
•Completed the acquisition of the remaining 55 percent interest in BANGL, LLC (“BANGL”) in July 2025 for approximately $700 million (the “BANGL Acquisition”), plus an earnout provision of up to $275 million. The earnout provision requires annual payments based on targeted EBITDA growth from 2026 to 2029 up to the maximum amount of $275 million.
•On August 5, 2025, MPLX announced the board of directors approved an incremental $1.0 billion unit repurchase authorization. The authorization has no expiration date.
•Acquired an additional five percent interest in the joint venture that owns and operates the Matterhorn Express Pipeline in June 2025.
Current Economic Environment
We continue to see robust production across our key operating regions, and in the Marcellus and Utica, rig counts remain steady, and volumes remain strong. Producer consolidation further illustrates the value in the liquids-rich acreage of the Utica, where condensate development activity continues to increase. In the Permian, steady drilling activity in multiple benches, rising gas-oil ratios, and the progression of export projects will support growth opportunities for our business. More broadly, we expect natural gas demand will accelerate over the next few years to provide increased electricity generation required for data centers and overall electric grid demand. As demand for natural gas-powered electricity rises, MPLX is well positioned to support the development plans of its producer-customers. MPLX is largely insulated against temporary volatility, due to our business model structured around long-term take-or-pay, fee-based contracts.
Non-GAAP Financial Information
Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include the non-GAAP financial measures of Adjusted EBITDA, DCF, adjusted free cash flow (“Adjusted FCF”), and Adjusted FCF after distributions.
Adjusted EBITDA is a financial performance measure used by management, industry analysts, investors, lenders, and rating agencies to assess the financial performance and operating results of our ongoing business operations. Additionally, we believe adjusted EBITDA provides useful information to investors for trending, analyzing and benchmarking our operating results from period to period as compared to other companies that may have different financing and capital structures. We define Adjusted EBITDA as net income adjusted for: (i) provision for income taxes; (ii) net interest and other financial costs; (iii) depreciation and amortization; (iv) income/(loss) from equity method investments; (v) distributions and adjustments related to equity method investments; (vi) impairment expense; (vii) noncontrolling interests; and (viii) other adjustments, as applicable.
DCF is a financial performance and liquidity measure used by management and by the board of directors of our general partner as a key component in the determination of cash distributions paid to unitholders. We believe DCF is an important financial measure for unitholders as an indicator of cash return on investment and to evaluate whether the partnership is generating sufficient cash flow to support quarterly distributions. In addition, DCF is commonly used by the investment community because the market value of publicly traded partnerships is based, in part, on DCF and cash distributions paid to unitholders. We define DCF as Adjusted EBITDA adjusted for: (i) deferred revenue impacts; (ii) sales-type lease payments, net of income; (iii) adjusted net interest and other financial costs; (iv) net maintenance capital expenditures; (v) equity method investment capital expenditures paid out; and (vi) other adjustments as deemed necessary.
Adjusted FCF and Adjusted FCF after distributions are financial liquidity measures used by management in the allocation of capital and to assess financial performance. We believe that unitholders may use this metric to analyze our ability to manage leverage and return capital. We define Adjusted FCF as net cash provided by operating activities adjusted for: (i) net cash used in investing activities; (ii) cash contributions from MPC; and (iii) cash distributions to noncontrolling interests. We define Adjusted FCF after distributions as Adjusted FCF less distributions to common and preferred unitholders.
We believe that the presentation of Adjusted EBITDA, DCF, Adjusted FCF and Adjusted FCF after distributions provides useful information to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to Adjusted EBITDA and DCF are net income and net cash provided by operating activities while the GAAP measure most directly comparable to Adjusted FCF and Adjusted FCF after distributions is net cash provided by operating activities. These non-GAAP financial measures should not be considered alternatives to net income or net cash provided by operating activities as they have important limitations as analytical tools because they exclude some but not all items that affect net income
28
and net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. These non-GAAP financial measures should not be considered in isolation or as substitutes for analysis of our results as reported under GAAP. Additionally, because non-GAAP financial measures may be defined differently by other companies in our industry, our definitions may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. For a reconciliation of Adjusted EBITDA and DCF to their most directly comparable measures calculated and presented in accordance with GAAP, see Results of Operations. For a reconciliation of Adjusted FCF and Adjusted FCF after distributions to their most directly comparable measure calculated and presented in accordance with GAAP, see Liquidity and Capital Resources.
Results of Operations
The following tables and discussion summarize our results of operations, including a reconciliation of Adjusted EBITDA and DCF from Net income and Net cash provided by operating activities, the most directly comparable GAAP financial measures. This discussion should be read in conjunction with Item 1. Financial Statements and is intended to provide investors with a reasonable basis for assessing our historical operations, but should not serve as the only criteria for predicting our future performance.

Three months ended June 30, 2025 compared to three months ended June 30, 2024
Net income attributable to MPLX decreased $128 million in the second quarter of 2025 compared to the second quarter of 2024.
Total revenues and other income decreased $49 million in the second quarter of 2025 compared to the second quarter of 2024 primarily due to:
•Increased Service revenue of $56 million primarily due to $41 million of crude oil and products logistics tariff and other fee increases, $5 million of additional marine equipment and $4 million of higher pipeline throughput.
•Increased Product related revenue of $45 million primarily due to higher NGL sales volumes in the Southwest and Marcellus of $78 million, partially offset by lower NGL prices in the Southwest and Southern Appalachia.
•Decreased Income from equity method investments of $155 million primarily driven by a $151 million gain in the second quarter of 2024 related to the dilution of our ownership interest in connection with the formation of a new joint venture to strategically combine the Whistler Pipeline and the Rio Bravo Pipeline project (the “Whistler Joint Venture Transaction”). See Supplemental Information on Equity Method Investments for additional information regarding the results of our equity method investments.
Total costs and expenses increased by $77 million in the second quarter of 2025 compared to the same period of 2024 primarily due to:
•Decreased Cost of revenues of $15 million primarily due to lower NGL purchases in the Rockies of $29 million, which are now reflected in purchased product costs due to changes in certain customer contracts, and $10 million lower project-related spending within our Crude Oil and Products Logistics segment, partially offset by higher net operating costs and repairs and maintenance costs of $21 million.
•Increased Purchased product costs of $56 million primarily due to higher NGL volumes in the Southwest of $45 million and higher NGL volumes in the Rockies of $28 million, which were previously recorded in cost of revenues due to changes in certain customer contracts. The increase was partially offset by lower NGL prices in the Southwest of $10 million and a decrease in the fair value of an embedded derivative in a natural gas purchase commitment of $7 million.
•Increased Purchases-related parties of $34 million due to $24 million of increased costs from MPC, primarily higher employee costs and $19 million of higher related party transportation costs.
31
Six months ended June 30, 2025 compared to six months ended June 30, 2024
Net income attributable to MPLX decreased $7 million in the first six months of 2025 compared to the same period of 2024.
Total revenues and other income increased $229 million in the first six months of 2025 compared to the same period of 2024 primarily due to:
•Increased Service revenue of $185 million primarily due to $64 million of crude oil and products logistics tariff and other fee increases and $61 million of higher pipeline throughput. Other increases in the first six months of 2025 include $12 million of incremental revenues related to the acquisition of gathering assets in the first quarter of 2024 and 2025, $10 million due to changes in presentation of rental income and service revenue as a result of a lease contract modification, $8 million of additional marine equipment and a $7 million non-recurring benefit associated with a customer agreement.
•Increased Product related revenue of $204 million primarily due to higher NGL sales volumes in the Southwest and Marcellus of $170 million, higher NGL prices in the Southwest and Marcellus of $29 million and a $27 million non-recurring benefit associated with a customer agreement.
•Decreased Income from equity method investments of $126 million primarily driven by a $151 million gain in the 2024 period related to the dilution of our ownership interest in connection with the Whistler Joint Venture Transaction, partially offset by a $25 million gain in the first half of 2025 related to the formation of a new joint venture, Texas City Logistics LLC. See Supplemental Information on Equity Method Investments for additional information regarding the results of our equity method investments.
•Decreased Other income of $32 million primarily due to a $20 million gain related to the acquisition of additional ownership interest in existing joint ventures and gathering assets in the Utica basin (the “Utica Midstream Acquisition”) and higher insurance proceeds of $19 million received in the first half of 2024, partially offset by marine services rate increases in the first half of 2025.
Total costs and expenses increased by $240 million in the first six months of 2025 compared to the same period of 2024 primarily due to:
•Increased Cost of revenues of $3 million partially due to higher net operating costs and repairs and maintenance costs of $39 million and the consolidation of expenses as a result of acquisitions of $6 million. The increases were partially offset by lower NGL purchases in the Rockies of $29 million, which are now reflected in purchased product costs due to changes in certain customer contracts, and $10 million lower project-related spending within our Crude Oil and Products Logistics segment.
•Increased Purchased product costs of $146 million primarily due to higher NGL volumes in the Southwest of $108 million, $28 million of higher NGL volumes in the Rockies, which were previously recorded in cost of revenues due to changes in certain customer contracts, and higher NGL prices in the Southwest of $26 million. The increases were partially offset by a decrease in the fair value of an embedded derivative in a natural gas purchase commitment of $11 million.
•Increased Purchases-related parties of $78 million due to $53 million of increased costs from MPC, primarily higher employee costs and $29 million of higher related party transportation costs.
Segment Results
In the fourth quarter of 2024, we renamed and modified the composition of our segments to better reflect the product-based value chains and growth strategy of MPLX’s operations. Certain prior period segment information has been recast for comparability.
We classify our business in the following reportable segments: Crude Oil and Products Logistics and Natural Gas and NGL Services. We evaluate the performance of our segments using Segment Adjusted EBITDA. Segment Adjusted EBITDA represents Adjusted EBITDA attributable to the reportable segments. Amounts included in net income and excluded from Segment Adjusted EBITDA include: (i) depreciation and amortization; (ii) net interest and other financial costs; (iii) income/(loss) from equity method investments; (iv) distributions and adjustments related to equity method investments; (v) impairment expense; (vi) noncontrolling interests; and (vii) other adjustments, as applicable. 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) are not tied to the operational performance of the segment.
The tables below present additional financial information about our reported segments for the three and six months ended June 30, 2025 and June 30, 2024.

Revenues in the second quarter of 2025 benefited from $78 million of higher NGL sales volumes in the Southwest and Marcellus partially offset by lower NGL prices in the Southwest and Southern Appalachia of $13 million.
Segment Adjusted EBITDA decreased $2 million in the second quarter of 2025 compared to the same period of 2024. This decrease is primarily due to $19 million of higher operating costs, $11 million of lower volumes in the Bakken and Rockies and $10 million of higher project related spending, partially offset by higher distributions and adjustments from equity method investments of $24 million and higher throughput fee rates of $10 million.
Six months ended June 30, 2025 compared to six months ended June 30, 2024
Total segment revenues and other income increased $127 million in the first six months of 2025 compared to the same period of 2024. In the first six months of 2025, revenues benefited from $170 million of higher NGL sales volumes in the Southwest and Marcellus, a $34 million non-recurring benefit associated with a customer agreement and $29 million of higher NGL prices in the Southwest and Marcellus. These increases were partially offset by lower income from equity method investments driven by a $151 million gain in the second quarter of 2024 related to the dilution of our ownership interest in connection with the Whistler Joint Venture Transaction.
Additional impacts from equity method investments included a $25 million gain in the first six months of 2025 related to the formation of a new joint venture, Texas City Logistics LLC, in addition to a $6 million benefit from the Utica Midstream Acquisition that was completed in the first quarter of 2024. See Supplemental Information on Equity Method Investments for additional information regarding the results of our equity method investments.
Segment Adjusted EBITDA increased $82 million in the first six months of 2025 compared to the same period of 2024. This increase is primarily due to $39 million of higher distributions and adjustments from equity method investments, a $37 million non-recurring benefit associated with a customer agreement and $20 million of higher throughput fee rates, partially offset by higher operating costs of $24 million.

Seasonality
The volume of crude oil and refined products transported and stored utilizing our assets is affected by the level of supply and demand for crude oil and refined products in the markets served directly or indirectly by our assets. The majority of effects of seasonality on the Crude Oil and Products Logistics segment’s revenues are mitigated through the use of capacity-based agreements and minimum volume commitments.
In our Natural Gas and NGL Services segment, we experience minimal impacts from seasonal fluctuations, which impact the demand for natural gas and NGLs and the related commodity prices caused by various factors including variations in weather patterns from year to year. Overall, our exposure to the seasonality fluctuations is limited due to the nature of our fee-based business.

Liquidity and Capital Resources
Cash Flows
Our cash and cash equivalents were $1,386 million at June 30, 2025 and $1,519 million at December 31, 2024. The change in cash and cash equivalents was due to the factors discussed below. Net cash provided by (used in) operating activities, investing activities and financing activities were as follows:
| Six Months Ended June 30, | |||||||||||
| (In millions) | 2025 | 2024 | |||||||||
| Net cash provided by (used in): | |||||||||||

| Financing activities | (1,912) | (293) | |||||||||
| Total | $ | (133) | $ | 1,453 | |||||||
Net cash provided by operating activities increased $126 million in the first six months of 2025 compared to the same period of 2024, primarily due to improved results from operations and higher cash distributions from equity method investments.
Net cash used in investing activities increased $93 million in the first six months of 2025 compared to the same period of 2024, primarily due to the purchase of an additional five percent ownership interest in the joint venture that owns and operates the Matterhorn Express pipeline for $151 million, higher contributions to equity method investments and higher capital spending partially offset by lower cash used for acquisitions.
Net cash used in financing activities increased $1,619 million in the first six months of 2025 compared to the same period of 2024 primarily driven by higher net debt repayments of $1,353 million, higher distributions to unitholders of $204 million, driven by the 12.5 percent increase in our quarterly distribution effective for the third quarter of 2024, and higher unit repurchases of $50 million.

Debt and Liquidity Overview
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.
40
On March 10, 2025, MPLX issued $1.0 billion aggregate principal amount of 5.400 percent senior notes due 2035 (the “2035 Senior Notes”) and $1.0 billion aggregate principal amount of 5.950 percent senior notes due 2055 (the “2055 Senior Notes”) in an underwritten public offering. The 2035 Senior Notes and 2055 Senior Notes were offered at prices to the public of 99.398 percent of par and 98.331 percent of par, respectively, each with interest payable semi-annually in arrears, commencing on October 1, 2025. On April 9, 2025, MPLX used $1.2 billion of the net proceeds from the issuance of the 2035 Senior Notes and 2055 Senior Notes to redeem all of (i) MPLX’s outstanding $1,189 million aggregate principal amount of 4.875 percent senior notes due June 2025 and (ii) MarkWest’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 17 to the unaudited consolidated financial statements for additional information on the BANGL Acquisition.
MPLX intends to use debt financing to restore liquidity after using cash on hand for the recently completed BANGL Acquisition and related debt repayments, and to fund the announced acquisition of Northwind Midstream.
Our intention is to maintain an investment-grade credit profile. As of June 30, 2025, the credit ratings on our senior unsecured debt were at or above investment grade level as follows:
| Rating Agency | Rating | |||||||
| Fitch | BBB (stable outlook) | |||||||
| Moody’s | Baa2 (stable outlook) | |||||||
| Standard & Poor’s | 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 our debt obligations do not contain credit rating triggers that would result in the acceleration of interest, principal or other payments solely in the event that our credit ratings are downgraded. However, any downgrades in the credit ratings of our senior unsecured debt ratings to below investment grade ratings could, among other things, increase the applicable interest rates and other fees payable under MPLX’s credit agreement (the “MPLX Credit Agreement”) and may limit our ability to obtain future financing, including refinancing existing indebtedness.
Our liquidity totaled $4.9 billion at June 30, 2025 consisting of:

| Cash and cash equivalents | 1,386 | ||||||||||||||||
| Total liquidity | $ | 4,886 | |||||||||||||||
We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our revolving credit facilities and access to capital markets. We believe that cash generated from these sources will be sufficient to meet our short-term and long-term funding requirements, including working capital requirements, capital expenditure requirements, contractual obligations, and quarterly cash distributions. Our material future obligations include interest on debt, payments of debt principal, purchase obligations including contracts to acquire property, plant and equipment, and our operating leases and service agreements. We may also, 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 market prices and upon such other terms as we deem appropriate and execute unit repurchases under our unit repurchase program.
MPC manages our cash and cash equivalents on our behalf directly with third-party institutions as part of the treasury services that it provides to us under our omnibus agreement. From time to time, we may also utilize other sources of liquidity, including the formation of joint ventures or sales of non-strategic assets.
The MPLX Credit Agreement matures in July 2027 and 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, we were in compliance with such covenants.
41
MPLX is party to a loan agreement with MPC, which is scheduled to expire, and borrowings under the loan agreement are scheduled to mature and become due and payable, on July 31, 2029, provided that MPC may demand payment of all or any portion of the outstanding principal amount of the loan, together with all accrued and unpaid interest and other amounts (if any), at any time prior to maturity.
Equity and Preferred Units Overview
Unit Repurchase Program
On August 2, 2022, we announced a board authorization for the repurchase of up to $1.0 billion of MPLX common units held by the public. On August 5, 2025, we announced the board of directors approved a $1.0 billion common unit repurchase authorization that is in addition to the $1.0 billion common unit repurchase authorization announced on August 2, 2022. The common unit 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 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:

(1) Cash paid for common units repurchased and average cost per unit includes commissions paid to brokers during the period.
As of June 30, 2025, we had $320 million remaining under the unit repurchase authorization before giving effect to the incremental $1.0 billion unit repurchase authorization announced on August 5, 2025.
Series A Redeemable Preferred Unit Conversions
On February 11, 2025, MPLX exercised its right to convert the remaining 6 million outstanding Series A preferred units into common units in accordance with the conversion provision outlined in our Sixth Amended and Restated Agreement of Limited Partnership.
Distributions
On July 29, 2025, MPLX declared a cash distribution for the second quarter of 2025, totaling $975 million, or $0.9565 per common unit. This distribution will be paid on August 15, 2025, to common unitholders of record on August 8, 2025. Although our partnership agreement requires that we distribute all of our available cash (as defined in the partnership agreement) each quarter, we do not otherwise have a legal obligation to distribute any particular amount per common unit.
The allocation of total cash distributions is as follows for the three and six months ended June 30, 2025 and June 30, 2024. MPLX’s distributions are declared subsequent to quarter end; therefore, the following table represents total cash distributions applicable to the period in which the distributions were earned.

Capital Expenditures
Our operations are capital intensive, requiring investments to expand, upgrade, enhance or maintain existing operations and to meet environmental and operational regulations. Our capital requirements consist of growth capital expenditures and maintenance capital expenditures. Growth capital expenditures are those incurred for acquisitions or capital improvements that we expect will increase our operating capacity for volumes gathered, processed, transported or fractionated or decrease operating expenses within our facilities or increase income from operations over the long term. Examples of growth capital expenditures include costs to develop or acquire additional pipeline, terminal, processing or storage capacity. In general, growth capital includes costs that are expected to generate additional or new cash flow for MPLX. In contrast, maintenance capital expenditures are expenditures made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives, or other capital expenditures that are incurred to maintain existing system volumes and related cash flows.
MPLX’s initial capital investment plan for 2025 is $2.0 billion, net of reimbursements and excluding capitalized interest, acquisitions and any incremental capital project expenditures associated with the pending Northwind Midstream acquisition. The initial capital investment plan includes growth capital of $1.7 billion and maintenance capital of $300 million. Growth capital expenditures and investments in affiliates during the six months ended June 30, 2025, 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. We continuously evaluate our capital plan and make changes as conditions warrant.
Our capital expenditures are shown in the table below:

(1) Investments in unconsolidated affiliates and additions to property, plant and equipment are shown as separate lines within investing activities in the Consolidated Statements of Cash Flows. Investments in unconsolidated affiliates for the six months ended June 30, 2025 exclude $151 million related to the acquisition of additional interest in the joint venture that owns and operates the Matterhorn Express Pipeline.
(2) Return of capital for the six months ended June 30, 2025 excludes a $21 million special distribution received in exchange for the contribution of assets to a joint venture. Return of capital for the six months ended June 30, 2024 excludes a $134 million cash distribution received in connection with the Whistler Joint Venture Transaction.
(3) Total growth capital expenditures for the six months ended June 30, 2025 and June 30, 2024 exclude acquisitions of $237 million and $622 million, respectively.
(4) Growth capital reimbursements are generally included in changes in deferred revenue within operating activities in the Consolidated Statements of Cash Flows. Maintenance capital reimbursements are included in the Contributions from MPC line within financing activities in the Consolidated Statements of Cash Flows.
We participate in joint ventures, which, in turn, also invest in capital projects. Certain of our joint ventures fund capital expenditures with project debt financings at the joint venture level or with cash from operations. Growth capital projects funded through debt at the joint venture level or cash from operations of the joint venture do not require capital contributions by us unless otherwise noted. Our pro-rata share of these growth capital projects for our equity method investments that have been funded at the joint venture level for the periods presented are shown in the table below.

Project debt at the joint venture level is typically secured by the assets owned by the joint venture and in certain cases, MPLX’s interest in the joint venture, but unless otherwise noted, is non-recourse to MPLX in excess of the value of MPLX’s investment in the joint venture. At June 30, 2025, debt held by our unconsolidated joint ventures based on our equity ownership percentage was $1.8 billion. See Note 16 to the accompanying unaudited consolidated financial statements for more information on MPLX’s guarantees of our joint venture entities’ obligations.
Cash Commitments
As of June 30, 2025, our material cash commitments included debt, finance and operating lease obligations, purchase obligations for services and to acquire property, plant and equipment, and other liabilities. During the six months ended June 30, 2025, our debt obligations increased by $300 million due to the issuance of senior notes and the repayment of senior notes, described in Liquidity and Capital Resources - Debt and Liquidity Overview. Additionally, in July 2025, MPLX completed the BANGL Acquisition and entered into an agreement to acquire Northwind Midstream, described in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Significant Financial and Other Highlights. There were no other material changes to our cash commitments outside the ordinary course of business.
Off-Balance Sheet Arrangements
Off-balance sheet arrangements comprise those arrangements that may potentially impact our liquidity, capital resources and results of operations, even though such arrangements are not recorded as liabilities under GAAP. Our off-balance sheet arrangements are limited to guarantees that are described in Note 16 of the unaudited consolidated financial statements and indemnities as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024.
Although these arrangements serve a variety of our business purposes, we are not dependent on them to maintain our liquidity and capital resources, and we are not aware of any circumstances that are reasonably likely to cause the off-balance sheet arrangements to have a material adverse effect on our liquidity and capital resources.
Transactions with Related Parties
As of June 30, 2025, MPC owned our general partner and an approximate 64 percent limited partner interest in us. We perform a variety of services for MPC related to the transportation of crude and refined products, including renewables, via pipeline or marine, as well as terminal services, storage services and fuels distribution and marketing services, among others. The services that we provide may be based on regulated tariff rates or on contracted rates. In addition, MPC performs certain services for us related to information technology, engineering, legal, accounting, treasury, human resources and other administrative services.
The below table shows the percentage of Total revenues and other income as well as Total costs and expenses with MPC:

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, but not limited to, the age and location of its operating facilities.
44
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 material changes to our environmental matters and compliance costs since our Annual Report on Form 10-K for the year ended December 31, 2024.
Tax Matters
Our U.S. federal income tax returns for the years 2019 through 2022 are currently under examination by the Internal Revenue Service.
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
We are exposed to market risks related to the volatility of commodity prices. We employ various strategies, including the potential use of commodity derivative instruments, to economically hedge the risks related to these price fluctuations. We are also exposed to market risks related to changes in interest rates. As of June 30, 2025, we did not have any open financial or commodity derivative instruments to hedge the economic risks related to interest rate fluctuations or the volatility of commodity prices, respectively; however, we continually monitor the market and our exposure and may enter into these arrangements in the future.
Commodity Price Risk
The information about commodity price risk for the three and six months ended June 30, 2025 does not differ materially from that discussed in Item 7A. Quantitative and Qualitative Disclosures about Market Risk of our Annual Report on Form 10-K for the year ended December 31, 2024.
Outstanding Derivative Contracts
See Notes 10 and 11 to the unaudited consolidated financial statements for more information about the fair value measurement of our derivative instruments, 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.
Interest Rate Risk and Sensitivity Analysis
Sensitivity analysis of the effect of a hypothetical 100-basis-point change in interest rates on outstanding third-party debt, excluding finance leases, is provided in the following table. 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.
| (In millions) | Fair Value as of June 30, 2025(1) | Change in Fair Value(2) | Change in Income Before Income Taxes for the Six Months Ended June 30, 2025(3) | ||||||||||||||
| Outstanding debt | |||||||||||||||||
| Fixed-rate | $ | 19,988 | $ | 1,650 | N/A | ||||||||||||
Variable-rate(4) | $ | — | $ | — | $ | — | |||||||||||
(1) Fair value was based on market prices, where available, or current borrowing rates for financings with similar terms and maturities.
(2) Assumes a 100-basis-point decrease in the weighted average yield-to-maturity at June 30, 2025.
(3) Assumes a 100-basis-point change in interest rates. The change to income before income taxes was based on the weighted average balance of all outstanding variable-rate debt for the six months ended June 30, 2025.
(4) MPLX had no outstanding borrowings on the MPLX Credit Agreement as of June 30, 2025.
At June 30, 2025, our portfolio of third‑party debt consisted of fixed-rate instruments and outstanding borrowings, if any, under the MPLX Credit Agreement. 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 portfolio 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 borrowings under our MPLX Credit Agreement, but may affect our results of operations and cash flows.

See Note 10 in 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 Rules 13a-15(e) and 15d-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 the chief executive officer and chief financial officer of our general partner. Based upon that evaluation, the chief executive officer and chief financial officer of our general partner 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. We use a threshold of $1 million for this purpose.
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.
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.
