MPLX LP Reports Third-Quarter 2025 Financial Results; Announces Increase to Quarterly Distribution of 12.5%

During the quarter, MPLX generated $1,431 million in net cash provided by operating activities and $1,468 million of distributable cash flow. Adjusted free cash flow was $(2,305) million, due in large part to the acquisitions of Northwind Midstream and the remaining 55% of BANGL, LLC. MPLX announced a third-quarter 2025 distribution of $1.0765 per common unit, resulting in distribution coverage of 1.3x for the quarter. The leverage ratio was 3.7x at the end of the quarter.

"MPLX delivered on its commitment to return capital, increasing the distribution 12.5% for the second consecutive year, reflecting conviction in our growth outlook," said Maryann Mannen, MPLX president and chief executive officer. "Strengthening the durability of mid-single digit adjusted EBITDA growth, we are investing in our key growth regions of the Permian and Marcellus basins, and executing on strategic portfolio optimization."

Financial Highlights (unaudited)

Segment Results

Crude Oil and Products Logistics

Crude Oil and Products Logistics segment adjusted EBITDA for the third quarter of 2025 increased by $43 million compared to the same period in 2024. The increase was primarily driven by higher rates, partially offset by higher operating expenses.

Natural Gas and NGL Services

Natural Gas and NGL Services segment adjusted EBITDA for the third quarter of 2025 increased by $9 million compared to the same period in 2024. The increase was driven by contributions from recently acquired assets and higher volumes, partially offset by higher operating expenses.

Strategic Update

MPLX enhanced its Permian natural gas and NGL value chains through the acquisition of a sour gas treating business in the Delaware basin for $2.4 billion. The transaction closed on August 29, 2025.

MPLX is optimizing the competitive positioning of its portfolio through the announced divestiture of Rockies gathering and processing assets for $1.0 billion. The transaction is expected to close in the fourth quarter of 2025.

In Natural Gas and NGL Services, MPLX is expanding its Permian to Gulf Coast integrated value chain, progressing long-haul pipeline growth projects to support increased producer activity, and investing in Permian and Marcellus processing capacity in response to producer demand. Updates on Natural Gas and NGL Services projects include:

Newly Announced

• Eiger Express Pipeline: In the third quarter, MPLX and its partners announced FID of the Eiger Express natural gas pipeline with the capacity to transport up to 2.5 billion cubic feet per day (Bcf/d) from the Permian basin to Katy, Texas, with connectivity to Agua Dulce via the Traverse pipeline. The Eiger Express pipeline is expected in service in mid-2028.

Ongoing

• Secretariat: A 200 million cubic feet per day (MMcf/d) processing plant increasing MPLX's gas processing capacity in the Permian basin to 1.4 Bcf/d; expected in service at the end of 2025.
• Harmon Creek III: Consists of a 300 MMcf/d processing plant and 40 thousand barrel per day (mbpd) de-ethanizer, which will increase MPLX's processing capacity in the Northeast to 8.1 Bcf/d and fractionation capacity to 800 mbpd; expected in service in the second half of 2026.
• Titan Complex (Northwind): The second sour gas treating plant is anticipated to be fully online in the second half of 2026, which will increase sour gas treating capacity in the Permian to over 400 MMcf/d from its acquired level of 150 MMcf/d.
• BANGL Pipeline: In July, MPLX acquired the remaining interest of BANGL, LLC. The BANGL pipeline is expanding from 250 mbpd to 300 mbpd and will enable liquids to reach MPLX's Gulf Coast fractionators. The expansion is expected in service in the second half of 2026.
• Blackcomb and Rio Bravo Pipelines: These pipelines (up to 2.5 Bcf/d and 4.5 Bcf/d, respectively) are designed to transport natural gas from the Permian to domestic and export markets along the Gulf Coast; expected in-service in the second half of 2026.
• Traverse Pipeline: A bi-directional 2.5 Bcf/d pipeline designed to transport natural gas along the Gulf Coast between Agua Dulce and the Katy area. The pipeline enhances optionality for shippers to access multiple premium markets, and is expected in service in 2027.
• Gulf Coast Fractionators: Two 150 mbpd fractionation facilities near Marathon Petroleum's (NYSE: MPC) Galveston Bay refinery. The fractionation facilities are expected in service in 2028 and 2029. MPC will purchase the offtake from the fractionators and intends to market it globally.
• LPG Export Terminal: Constructing a 400 mbpd LPG export terminal in an advantaged location for global market access, and an associated pipeline, which is anticipated in service in 2028; a strategic partnership with ONEOK.

In Crude Oil and Products Logistics, MPLX is expanding its crude gathering pipelines in the Permian and Bakken basins, and investing in projects targeted at the expansion or de-bottlenecking of assets.

Non-GAAP references

In addition to our financial information presented in accordance with U.S. generally accepted accounting principles (GAAP), management utilizes additional non-GAAP measures to analyze our performance. This press release and supporting schedules include the non-GAAP measures adjusted EBITDA; consolidated debt to last twelve months adjusted EBITDA, which we refer to as our leverage ratio; distributable cash flow (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; (viii) transaction-related costs; and (ix) 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 base 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.

Leverage ratio is a liquidity measure used by management, industry analysts, investors, lenders and rating agencies to analyze our ability to incur and service debt and fund capital expenditures.

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 GAAP 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 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, DCF, Adjusted FCF, Adjusted FCF after distributions and our leverage ratio to their most directly comparable measures calculated and presented in accordance with GAAP, see the tables below.
