        billion
    --  Targeting positive free cash flow, after capital investments and
        distributions, in 2021

MPLX LP (NYSE: MPLX) today reported a fourth-quarter 2019 net loss attributable to MPLX of $581 million compared with net income of $434 million for the fourth quarter of 2018. Adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) attributable to MPLX was $1.3 billion, compared with $1.2 billion in the fourth quarter of 2018. Fourth-quarter 2019 results include non-cash impairment charges of $1.2 billion, primarily related to goodwill associated with the Andeavor Logistics (ANDX) gathering and processing businesses acquired by Marathon Petroleum Corporation (NYSE: MPC) as part of its combination with Andeavor in October 2018.

The Logistics and Storage (L&S) segment reported segment income from operations of $677 million and adjusted EBITDA of $853 million for the quarter, up $40 million and $44 million, respectively, versus the fourth quarter of last year. The Gathering and Processing (G&P) segment reported a segment loss from operations of $1.0 billion and adjusted EBITDA of $466 million for the quarter, down $1.3 billion and up $29 million, respectively, on a year-over-year basis. G&P results include the non-cash impairment charges discussed above.

MPLX today announced an updated 2020 growth capital target of approximately $1.5 billion from the previously announced target of approximately $2.0 billion. Michael J. Hennigan, president and chief executive officer, commented, "We have further streamlined our project portfolio to focus on projects that deliver the highest returns. Our continued efforts to high-grade our capital spending will help accomplish our target of positive free cash flow generation, after capital investments and distributions, in 2021. This inflection is expected to allow both the funding of our distribution and capital program entirely from internally generated cash flow, as well as increase our flexibility to reduce debt or repurchase units."

During the quarter, MPLX generated $1.1 billion in net cash provided by operating activities and $1.0 billion of distributable cash flow, which provided adjusted distribution coverage of 1.42 times. MPLX also announced its 28th consecutive distribution increase, to $0.6875 per common unit, a $0.01 increase over the prior quarter and a 6.2% increase over the prior year's fourth quarter.

Logistics & Storage

L&S segment income from operations and adjusted EBITDA for the fourth quarter of 2019 increased by $40 million and $44 million, respectively, compared to the same period in 2018. The increase was primarily due to the acquisition of ANDX and the performance of the underlying base business.

Total pipeline throughputs were 5.1 million barrels per day in the fourth quarter, relatively flat versus the same quarter of 2018, despite volume impacts related to project work at MPC's Garyville refinery. The average tariff rate was $0.90 per barrel for the quarter. Terminal throughput was 3.3 million barrels per day for the quarter, an increase of 4% versus the same quarter of 2018.

Gathering & Processing

G&P segment income from operations and segment adjusted EBITDA for the fourth quarter of 2019 decreased by $1.3 billion and increased by $29 million, respectively, compared to the same period in 2018. Year-over-year results were impacted by non-cash impairment charges of $1.2 billion, primarily related to goodwill associated with the ANDX G&P businesses acquired by MPC as part of its combination with Andeavor in October 2018. In the fourth quarter of 2019:

    --  Gathered volumes: 6.2 billion cubic feet per day, a 5% increase versus
        the fourth quarter of 2018
    --  Processed volumes: 8.8 billion cubic feet per day, a 7% increase versus
        the fourth quarter of 2018
    --  Fractionated volumes: 557 thousand barrels per day, an 11% increase
        versus the fourth quarter of 2018

In the Marcellus and Utica, the company continued to experience significant year-over-year growth:

    --  Gathered volumes averaged 3.6 billion cubic feet per day (bcf/d) in the
        fourth quarter, an 11% increase versus the fourth quarter of 2018. For
        the full year, gathered volumes increased 18% year-over-year
    --  Processed volumes averaged 6.1 bcf/d in the fourth quarter, a 7%
        increase versus the fourth quarter of 2018 driven by the addition of the
        Sherwood 12 and 13 processing plants, which were placed in service
        during the quarter. For the full year, processed volumes increased 14%
        year-over-year
    --  Fractionated volumes averaged 487 thousand barrels per day in the fourth
        quarter, a 9% increase versus the fourth quarter of 2018. The increase
        was primarily driven by higher volumes from expansions at the Hopedale
        and Sherwood complexes. For the full year, fractionated volumes
        increased 12% year-over-year

Strategic Update

Today, MPLX announced an updated 2020 growth capital target of approximately $1.5 billion from the previously announced target of approximately $2.0 billion. The company also announced it is targeting positive free cash flow, after capital investments and distributions, in 2021. This inflection is expected to allow both the funding of its distribution and capital program entirely from internally generated cash flow. Removing MPLX's reliance on external funding and shifting to a model focused on generating cash flow beyond the needs of the business is anticipated to enable MPLX to focus its capital allocation toward opportunities like debt reduction or unit repurchases.

In the L&S segment, 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 Wink-to-Webster crude oil pipeline, in which MPLX has an equity interest, remains on schedule to be completed in the first half of 2021. The 36-inch diameter pipeline will originate in the Permian Basin and have destination points in the Houston market, including MPC's Galveston Bay refinery.

Also in the Permian, the Whistler Pipeline is being designed to transport approximately 2 bcf/d of natural gas from Waha, Texas, to the Agua Dulce market in south Texas, ultimately reaching MPC's Galveston Bay refinery. MPLX has an equity interest in Whistler, which is expected to be placed in service in the second half of 2021.

MPLX continues to progress its Permian-to-Gulf Coast NGL pipeline, called BANGL, which has a planned capacity of approximately 500 thousand barrels per day. The company expects a final investment decision in the near term.

Reversal of the Capline pipeline continues to progress, with a purge of the mainline completed in the fourth quarter. Once reversed, Capline will be capable of supplying discounted mid-continent and Canadian crude to St. James, Louisiana, which has a direct connection to MPC's Garyville refinery. Capline, which is partially owned by MPC and operated by MPLX, is expected to begin light crude service in mid-2021, with heavy crude service expected in 2022.

To support additional growth in the G&P segment, following the Sherwood 12 and Torñado processing plants that came online in October 2019, MPLX completed the Sherwood 13 processing plant late in the fourth quarter. This added another 200 million cubic feet per day of incremental capacity. The company expects to place in service the Omega 2 processing plant in the STACK shale play in Oklahoma in the first quarter of 2020, the Preakness processing plant in the Permian in the second quarter of 2020, and the Smithburg 1 processing plant in the Marcellus in the third quarter of 2020.

Financial Position and Liquidity

As of Dec. 31, 2019, MPLX had $15 million in cash, $3.5 billion available through its bank revolving credit facility expiring in July 2024 and $0.9 billion available through its intercompany loan agreement with MPC. The company's leverage ratio was 4.1 times at Dec. 31, 2019. 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 and consolidated debt to last twelve months pro forma adjusted EBITDA, which we refer to as our leverage ratio, distributable cash flow (DCF) and distribution coverage ratio. The amount of adjusted EBITDA and DCFgenerated 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 for income taxes; (iii) amortization of deferred financing costs; (iv) non-cash equity-based compensation; (v) net interest and other financial costs; (vi) income from equity method investments; (vii) distributions and adjustments related to equity method investments; (viii) unrealized derivative gains and losses; (ix) acquisition costs; (x) noncontrolling interest and (xi) other adjustments as deemed necessary. In general, we define DCF as adjusted EBITDA adjusted for (i) deferred revenue impacts; (ii) net interest and other financial costs; (iii) maintenance capital expenditures; (iv) equity method investment capital expenditures paid out; and (v) other non-cash items.

The Partnership makes a distinction between realized or unrealized gains and losses on derivatives. During the period when a derivative contract is outstanding, we record changes in the fair value of the derivative as an unrealized gain or loss. When a derivative contract matures or is settled, we reverse the previously recorded unrealized gain or loss and record the realized gain or loss of the contract.

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.

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.

We have based our forward-looking statements on our current expectations, estimates and projections about our business and industry. We caution that these statements are not guarantees of future performance and you should not rely unduly on them, as they involve risks, uncertainties, and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. While our management considers these assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in our forward-looking statements. We undertake no obligation to update any forward-looking statements except to the extent required by applicable law.

                                   the issuance of approximately 102
                                   million units issued to public
                        unitholders and approximately 161
                        million units issued to MPC in

                                   acquisition, 600,000 ANDX

     (a)            MPLX 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.



     (b)            The adjusted EBITDA and DCF adjustments
                      related to predecessor are excluded from
                      adjusted EBITDA attributable to MPLX LP and
           DCF attributable to GP and LP unitholders

                      Series A and Series B preferred units as
                      well as cash distributions earned by the
                      Series
           B preferred (as the Series B preferred units
           are declared and payable semi-annually)
           assuming a distribution is declared by the
           Board
           of Directors. Cash distributions declared/to
           be paid to holders of the Series A and
           Series B preferred units are not available
           to common
          unitholders.

     (a) 
              MPLX 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.



     (b) 
              The adjusted EBITDA and DCF adjustments related to predecessor are excluded from adjusted EBITDA attributable to MPLX LP and
          DCF attributable to GP and LP unitholders prior to the acquisition date.



     (c) 
              Includes MPLX distributions declared on the Series A and Series B preferred units as well as cash distributions earned by the Series
          B preferred units (as the Series B preferred units are declared and payable semi-annually) assuming a distribution is declared by the
          Board of Directors. Cash distributions declared/to be paid to holders of the Series A and Series B preferred units are not available to
          common unitholders.
