Logistics & Storage

L&S segment income from operations for the third quarter of 2021 increased by $75 million compared to the same period in 2020, while segment adjusted EBITDA for the third quarter of 2021 increased by $11 million compared to the same period in 2020. Results for the quarter benefited from higher revenue and lower operating expenses.

2

Total pipeline throughputs were 5.5 million barrels per day (bpd) in the third quarter, 17% higher than the same quarter of 2020. The average tariff rate was $0.90 per barrel for the quarter, a decrease of 3% versus the same quarter of 2020. Terminal throughput was 3.0 million bpd for the quarter, an increase of 13% versus the same quarter of 2020.

Gathering & Processing

G&P segment income from operations for the third quarter of 2021 increased by $57 million compared to the third quarter of 2020. Adjusted EBITDA for the third quarter of 2021 increased by $43 million compared to the same period in 2020 as a result of higher natural gas liquids prices and lower operating expenses. These benefits were partially offset by lower processed and fractionated volumes.

In the third quarter of 2021:

•Gathered volumes averaged 5.4 billion cubic feet per day (bcf/d), roughly flat with the third quarter of 2020.

•Processed volumes averaged 8.4 bcf/d, a 2% decrease versus the third quarter of 2020.

•Fractionated volumes averaged 553 thousand bpd, a 2% decrease versus the third quarter of 2020.

In the Marcellus:

•Gathered volumes averaged 1.4 bcf/d in the third quarter, a 5% increase versus the third quarter of 2020.

•Fractionated volumes averaged 487 thousand bpd in the third quarter, a 2% increase versus the third quarter of 2020.

Strategic Update

MPLX remains focused on executing the strategic priorities of strict capital discipline, lowering the cost structure, and portfolio optimization. The partnership announced it is pursuing strategic alternatives for its Alaskan logistics and storage operations, which could include a sale.

MPLX continues to advance its strategy of creating integrated crude oil and natural gas logistics systems from the Permian to the U.S. Gulf Coast. The three major pipeline projects in this region have either already started up or remain on track to begin service in 2021.

The Wink to Webster crude oil pipeline, in which MPLX has a 15% equity interest, continues to progress, with segments and assets coming online throughout 2021. The 36-inch diameter pipeline, of which 100% of the contractible capacity is committed with minimum volume commitments (MVCs), will originate in the Permian Basin and have destination points in the Houston market, with connectivity to Marathon Petroleum Corporation's (MPC's) Galveston Bay refinery.

Also in the Permian, the Whistler Pipeline is designed to transport approximately 2 bcf/d of natural gas to the Agua Dulce market in south Texas. MPLX has an approximate 38% ownership in Whistler, which was placed into service in the beginning of July and is expected to ramp up throughout 2022. Whistler is more than 90% committed with MVCs.

On October 1, MPLX, WhiteWater Midstream, and West Texas Gas, Inc. (WTG) through a joint venture (JV) placed in-service a solution for natural gas liquids takeaway capacity from MPLX and WTG gas processing plants to Sweeny, Texas. The JV currently utilizes existing infrastructure with limited new construction.

MPLX continues to evaluate opportunities to expand its logistics to meet the needs of today and participate in an energy-diverse future.

Financial Position and Liquidity

As of September 30, 2021, MPLX had $39 million in cash and full availability of its $3.5 billion bank revolving credit facility. The company's leverage ratio was 3.7x.

The partnership repurchased $155 million of common units held by the public in the third quarter of 2021. As of September 30, 2021, MPLX has approximately $500 million remaining available under the current $1 billion board authorization.

MPLX remains committed to maintaining an investment-grade credit profile.

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 pro forma adjusted EBITDA, which we refer to as our leverage ratio; distributable cash flow (DCF); distribution coverage ratio; and free cash flow (FCF) and excess/deficit cash flow.

4

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) depreciation and amortization; (ii) provision/benefit for income taxes; (iii) amortization of deferred financing costs; (iv) gain/loss on extinguishment of debt; (v) non-cash equity-based compensation; (vi) impairment expense; (vii) net interest and other financial costs; (viii) income/loss from equity method investments; (ix) distributions and adjustments related to equity method investments; (x) unrealized derivative gains/losses; (xi) acquisition costs; (xii) noncontrolling interest and (xiii) other adjustments as deemed necessary. 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 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.

FCF and excess/deficit cash flow 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 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 excess/deficit cash flow as FCF adjusted for 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.
