Segment Results


(In millions)		Three Months Ended March 31,
Segment adjusted EBITDA attributable to MPLX LP (unaudited)		2024		2023
Logistics and Storage	$	1,098	$	1,026
Gathering and Processing	$	537	$	493

Logistics & Storage

L&S segment adjusted EBITDA for the first quarter of 2024 increased by $72 million compared to the same period in 2023. The increase was primarily driven by higher rates and growth from equity affiliates. Due to contract structure, refinery volume changes had limited financial impact.

Total pipeline throughputs were 5.3 million barrels per day (bpd) in the first quarter, a decrease of 6% versus the same quarter of 2023. The average pipeline tariff rate was $1.02 per barrel for the quarter, an increase of 13% versus the same quarter of 2023. Terminal throughput was 2.9 million bpd for the quarter, a decrease of 5% versus the same quarter of 2023.

Gathering & Processing

G&P segment adjusted EBITDA for the first quarter of 2024 increased by $44 million compared to the same period in 2023, primarily due to higher volumes and a $20 million non-cash gain associated with the acquisition of the remaining interest of a Utica joint venture, partially offset by higher operating expenses.

In the first quarter of 2024:

Gathered volumes averaged 6.2 billion cubic feet per day (bcf/d), a 2% decrease from the first quarter of 2023.
Processed volumes averaged 9.4 bcf/d, a 9% increase versus the first quarter of 2023.
Fractionated volumes averaged 632 thousand bpd, a 7% increase versus the first quarter of 2023.

In the Marcellus:

Gathered volumes averaged 1.5 bcf/d in the first quarter, a 10% increase versus the first quarter of 2023.
Processed volumes averaged 5.9 bcf/d in the first quarter, a 7% increase versus the first quarter of 2023.
Fractionated volumes averaged 553 thousand bpd in the first quarter, a 4% increase versus the first quarter of 2023.

Strategic Update

MPLX enhanced its Utica footprint through the acquisition of additional ownership interest in existing joint ventures and a dry gas gathering system for $625 million. The transaction closed in March 2024.

MPLX also announced the expansion of its Permian natural gas value chain, increasing its footprint in the region for future growth. MPLX entered into a definitive agreement to strategically combine the Whistler Pipeline and Rio Bravo Pipeline project in a newly formed joint venture. The transaction is expected to close in the second quarter of 2024, subject to receipt of required regulatory approvals and satisfaction of other customary closing conditions.

In the L&S segment, MPLX is expanding its natural gas and natural gas liquids long-haul and crude gathering pipelines supporting the Permian and Bakken basins. Specifically in the Permian, working with its partners, MPLX is progressing its natural gas strategy. Progress continues on the Agua Dulce Corpus Christi (ADCC) Pipeline lateral, which is expected to be in service in the third quarter of 2024. MPLX is progressing its natural gas liquids strategy with the expansion of the BANGL joint venture pipeline to a capacity of 200 thousand bpd, with expected completion in the first half of 2025.

In the G&P segment, MPLX remains focused on the Permian and Marcellus basins in response to producer demand. In the Delaware basin in the Permian, the 200 million cubic feet per day (mmcf/d) Preakness ll processing plant is approaching startup. MPLX is constructing its seventh processing plant in the basin, Secretariat, which is expected online in the second half of 2025. These new plants will bring MPLX processing capacity in the Delaware basin to 1.4 bcf/d. In the Marcellus, the 200 mmcf/d Harmon Creek ll processing plant was placed into operation in the first quarter.

Financial Position and Liquidity

As of March 31, 2024, MPLX had $385 million in cash, $2.0 billion available on its bank revolving credit facility, and $1.5 billion available through its intercompany loan agreement with Marathon Petroleum Corp. (NYSE: MPC). MPLX's leverage ratio was 3.2x, while the stability of cash flows supports leverage in the range of 4.0x.

The partnership repurchased $75 million of common units held by the public in the first quarter of 2024. As of March 31, 2024, MPLX had approximately $771 million remaining available under its unit repurchase authorization.

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; 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 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.
