Financial Highlights (unaudited)

Segment Results

Crude Oil and Products Logistics

Crude Oil and Products Logistics segment adjusted EBITDA for the second quarter of 2026 increased by $23 million compared to the same period in 2025. The increase was primarily driven by higher rates across the business units and increased butane blending, partially offset by lower crude pipeline throughputs and higher operating expenses.

Natural Gas and NGL Services

Natural Gas and NGL Services segment adjusted EBITDA for the second quarter of 2026 increased by $62 million compared to the same period in 2025. The increase was driven by increased volumes including growth from equity affiliates and acquisitions, partially offset by the divestiture of non-core gathering and processing assets in 2025.

Strategic Update

MPLX is increasing its 2026 growth capital spending outlook by $500 million, to $2.9 billion, primarily reflecting the accelerated execution of the Gulf Coast fractionation project to meet global demand for U.S. energy. MPLX plans to invest over 90% of organic growth capital toward opportunities to meet growing natural gas and NGL infrastructure needs. With projects concentrated in the Permian and Marcellus, two of the most prolific and competitive basins in North America, investments in these value chains reflect the partnership's confidence in the long-term fundamentals of the energy market, offer some of the most compelling investments in the midstream sector, and are expected to generate mid-teens returns.

Financial Position and Liquidity

As of June 30, 2026, MPLX had $1.0 billion in cash, $2.5 billion available on its bank revolving credit facility, and $1.5 billion available through its intercompany loan agreement with MPC. MPLX's leverage ratio was 3.7x, while the stability of cash flows supports leverage in the range of 4.0x.

The partnership repurchased $50 million of common units held by the public in the second quarter of 2026. As of June 30, 2026, MPLX had approximately $1.0 billion remaining available under its unit repurchase authorizations.

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.
