Table of Contents
We have based our forward-looking statements on our current expectations, estimates and projections about our industry and our business. 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 forecasted in our forward-looking statements. Differences
between actual results and any future performance suggested in our forward-looking statements could result from a variety of factors, including the
following:

volatility or degradation in general economic, market, industry or business conditions;

·

and the expansion and retirement of pipeline capacity, processing, fractionation and treating facilities in response to market conditions;

SUMMARY
This summary highlights information contained elsewhere in or incorporated by reference into this prospectus. This summary does not contain
all of the information that you should consider in making your investment decision. You should read the following summary together with the entire
prospectus, including the more detailed information regarding our company, the Exchange Notes and the consolidated financial statements and the
related notes incorporated by reference into this prospectus. You should also carefully consider, among other things, the matters discussed in the
section entitled "Risk Factors" in this prospectus before making an investment decision. Some of the statements in this prospectus constitute forward-
looking statements. See "Cautionary Note Regarding Forward-Looking Statements." Except as otherwise indicated or unless the context otherwise
requires, the term "Notes" refers collectively to the Original Notes and the Exchange Notes.
Company
Marathon Petroleum Corporation has 131 years of experience in the energy business with roots tracing back to the formation of the Ohio Oil
Company in 1887. We are a leading, integrated, downstream energy company headquartered in Findlay, Ohio. With the Andeavor acquisition (as
described further below), we are the largest independent petroleum product refining, marketing, retail and midstream business in the United States.
We operate the nation's largest refining system with more than 3 million barrels per day of crude oil capacity across 16 refineries. MPC's marketing
system includes branded locations across the United States. We also own and operate retail convenience stores across the United States. MPC's
midstream operations are primarily conducted through MPLX and ANDX, which own and operate crude oil and light product transportation and
logistics infrastructure as well as gathering, processing and fractionation assets. We own the general partner and majority limited partner interests in
these two midstream companies.
Our common stock is traded on the New York Stock Exchange, which we refer to as "NYSE," under the symbol "MPC." Our principal
executive offices are located at 539 S. Main Street, Findlay, Ohio 45840, and our telephone number at that location is (419) 421-2121.
https://www.sec.gov/Archives/edgar/data/1510295/000119312519113451/d720987d424b3.htm[5/24/2019 1:11:01 PM]

424B3
On October 1, 2018, we completed the Andeavor acquisition pursuant to a merger agreement, dated as of April 29, 2018, as amended, among
MPC, Andeavor and certain affiliates of MPC, which we refer to as the "merger agreement." Pursuant to the merger agreement, Andeavor
stockholders had the option to elect to receive 1.87 shares of MPC common stock or $152.27 in cash per share of Andeavor common stock cancelled
in the Andeavor acquisition. The merger agreement included election proration provisions that resulted in approximately 22.9 million shares of
Andeavor common stock being converted into cash consideration and the remaining 128.2 million shares of Andeavor common stock being converted
into stock consideration. Andeavor stockholders received in the aggregate approximately 239.8 million shares of MPC common stock and
approximately $3.5 billion in cash in the Andeavor acquisition.
At the time of the Andeavor acquisition, Andeavor had outstanding an aggregate principal amount of $3.375 billion in senior notes consisting of:
$475 million aggregate principal amount of 5.375% senior notes due October 1, 2022; $850 million aggregate principal amount of 4.750% senior
notes due December 15, 2023; $300 million aggregate principal amount of 5.125% senior notes due April 1, 2024; $750 million aggregate principal
amount of 5.125% senior notes due December 15, 2026; $500 million aggregate principal amount of 3.800% senior notes due April 1, 2028; and
$500 million aggregate principal amount of 4.500% senior notes due April 1, 2048, which we refer to collectively as the "Andeavor senior notes." On
October 2, 2018, we completed offers to exchange any and all outstanding Andeavor senior notes for (1) up to $3.375 billion aggregate principal
amount of new notes issued by MPC having the same maturity and interest rates as the Andeavor senior notes and (2) cash of $1 for each $1,000 of
principal amount exchanged. Approximately 86.1 percent, or approximately $2.905 billion, of the Andeavor senior notes were tendered and accepted
in the Exchange Offers, and we issued the Original Notes pursuant to the Exchange Offers.

RISK FACTORS
The terms of each series of Exchange Notes are identical in all material respects to those of the corresponding series of Original Notes, except that the
transfer restrictions, registration rights and related special interest provisions applicable to the Original Notes will not apply to the Exchange Notes. Before
making a decision regarding the Exchange Offers, you should carefully consider the risks described below and all of the information contained or
incorporated by reference into this prospectus, including the information in Part I, Item 1A, "Risk Factors," in our most recent Annual Report on Form
10-K and subsequent filings made with the SEC and incorporated by reference in this prospectus, before making an investment decision. The risks and
uncertainties we have described are not the only ones we face. Additional risks and uncertainties that are not yet identified may also materially harm our
business, operating results and financial condition and could result in a complete loss of your investment. See "Cautionary Note Regarding Forward-
Looking Statements" in this prospectus.
Risks Related to the Exchange Offers
If you fail to exchange your Original Notes, they will continue to be restricted securities and will likely become less liquid.
Original Notes that you do not tender, or we do not accept, will, following the Exchange Offers, continue to be restricted securities, and you may not
offer to sell them except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We will
issue Exchange Notes in exchange for Original Notes of the corresponding series pursuant to the Exchange Offers only following the satisfaction of the
procedures and conditions set forth in "The Exchange Offers--Procedures for Tendering" and "The Exchange Offers--Conditions to the Exchange
Offers." These procedures and conditions include timely receipt by the exchange agent of a confirmation of book-entry transfer of the Original Notes being
tendered and an agent's message from DTC.
Because we anticipate that all or substantially all holders of Original Notes will elect to exchange their Original Notes in these Exchange Offers, we
expect that the market for any Original Notes remaining after the completion of the Exchange Offers will be substantially limited. Any Original Notes
tendered and exchanged in the Exchange Offers will reduce the aggregate principal amount of the Original Notes of the applicable series outstanding. If
you do not tender your Original Notes following the Exchange Offers, you generally will not have any further registration rights, and your Original Notes
will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for the Original Notes of each series is likely to be
adversely affected.
You must follow the appropriate procedures to tender your Original Notes or they will not be exchanged.
The Exchange Notes will be issued in exchange for the Original Notes only after timely receipt by the exchange agent of the Original Notes or a
book-entry confirmation related thereto, an agent's message and all other required documentation. If you want to tender your Original Notes in exchange
for Exchange Notes, you should allow sufficient time to ensure timely delivery. Neither we nor the exchange agent are under any duty to give you
notification of defects or irregularities with respect to tenders of Original Notes for exchange. Original Notes that are not tendered or are tendered but not
accepted will, following the Exchange Offer, continue to be subject to the existing transfer restrictions. In addition, if you tender the Original Notes in the
Exchange Offer to participate in a distribution of the Exchange Notes, you will be required to comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction. For additional information, please refer to the sections entitled "The Exchange
Offers" and "Plan of Distribution" later in this prospectus.
The Exchange Offers may not be consummated.
Each of the Exchange Offers is subject to customary conditions set forth in "The Exchange Offers--Conditions to the Exchange Offers" later in this
prospectus. These conditions are for our sole benefit and may be asserted by us with respect to all or any portion of the Exchange Offers regardless of the
circumstances, including any action or inaction by us, giving rise to the condition or may be waived by us in whole or in part at any time or from time to
time in our sole discretion. We reserve the right, notwithstanding the satisfaction of these conditions, to terminate or amend the Exchange Offers. In
