Logistics & Storage

L&S segment adjusted EBITDA for the first quarter of 2023 increased by $122 million compared to the same period in 2022. These increases were primarily driven by growth in throughputs and higher rates.

Total pipeline throughputs were 5.6 million barrels per day (bpd) in the first quarter, an increase of 6% versus the same quarter of 2022. The average tariff rate was $0.90 per barrel for the quarter, an increase of 1% versus the same quarter of 2022. Terminal throughput was 3.1 million bpd for the quarter, an increase of 5% versus the same quarter of 2022.

Gathering & Processing

G&P segment adjusted EBITDA for the first quarter of 2023 increased by $4 million compared to the same period in 2022 as higher throughput fees and volumes offset lower natural gas liquids prices.

In the first quarter of 2023:
Gathered volumes averaged 6.4 billion cubic feet per day (bcf/d), a 21% increase from the first quarter of 2022.
Processed volumes averaged 8.6 bcf/d, a 4% increase versus the first quarter of 2022.

Fractionated volumes averaged 593 thousand bpd, a 13% increase versus the first quarter of 2022.

In the Marcellus:
Gathered volumes averaged 1.4 bcf/d in the first quarter, a 4% increase versus the first quarter of 2022.
Processed volumes averaged 5.6 bcf/d in the first quarter, flat versus the first quarter of 2022.
Fractionated volumes averaged 533 thousand bpd in the first quarter, a 14% increase versus the first quarter of 2022.

Strategic Update

In the L&S segment, MPLX continues to expand natural gas 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 with the expansion of the Whistler pipeline from 2.0 bcf/d to 2.5 bcf/d, and the associated ADCC pipeline lateral into the Corpus Christi domestic and export markets.

In the G&P segment, MPLX remains focused on the Permian and Marcellus basins in response to producer demand. MPLX is progressing its sixth 200 mmcf/d processing plant in the Permian basin, Preakness ll, which is expected online in the first half of 2024. In the Marcellus, MPLX is progressing Harmon Creek ll, a 200 mmcf/d processing plant expected online in the first half of 2024.

Financial Position and Liquidity

As of March 31, 2023, MPLX had $393 million in cash, $2 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 3.5x, below its stated target of 4.0x.

On February 9, 2023, MPLX issued $1.1 billion aggregate principal amount of 5.000% senior notes due 2033 and $0.5 billion aggregate principal amount of 5.650% senior notes due 2053.

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 facilitate comparisons of past performance and future periods. 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); distribution coverage ratio; adjusted free cash flow (Adjusted FCF); and adjusted free cash flow after distributions. The amount of adjusted EBITDA and DCF generated is considered by the board of directors of our general partner in approving the Partnership's cash distribution. Adjusted EBITDA and DCF should not be considered separately from or as a substitute for net income, income from operations, or cash flow as reflected in our financial statements. The GAAP measures most directly comparable to adjusted EBITDA and DCF are net income and net cash provided by operating activities. We define Adjusted EBITDA as net income adjusted for: (i) provision for income taxes; (ii) 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) gain on sales-type leases; (vii) impairment expense; (viii) noncontrolling interests; and (ix) other adjustments, as applicable. In general, we define DCF as adjusted EBITDA adjusted for (i) deferred revenue impacts; (ii) sales-type lease payments, net of income; (iii) net interest and other financial costs; (iv) net maintenance capital expenditures; (v) equity method investment maintenance capital expenditures paid out; and (vi) other adjustments as deemed necessary.

The Partnership makes a distinction between realized and 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.

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.

DCF is a financial performance measure used by management 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.


4


Adjusted FCF and adjusted free cash flow after distributions are financial performance 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; (iii) cash contributions from noncontrolling interests and (iv) cash distributions to noncontrolling interests. We define adjusted free cash flow after distributions as Adjusted FCF less base distributions to common and preferred unitholders.

Distribution coverage ratio is a financial performance measure used by management to reflect the relationship between the partnership's financial operating performance and cash distribution capability. We define the distribution coverage ratio as the ratio of DCF attributable to GP and LP unitholders to total GP and LP distributions declared.

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.
