Subject:
MPC and Andeavor Combination to Create A Leading U.S. Refining, Midstream and Retail Company
From:
Gary R. Heminger

Fellow employees,

Today Marathon Petroleum Corporation announced our agreement to enter into a strategic combination with Andeavor, formerly Tesoro, an independent refining, marketing and logistics business, to create a leading U.S. refining, marketing and midstream company.

It is important to remember that today’s announcement is just the first step in the process. The transaction is subject to customary closing conditions, including regulatory and shareholder approvals. Until the transaction closes, Marathon Petroleum Corporation and Andeavor will continue to operate as separate companies. It is critical that we all stay focused on safety, environmental stewardship and doing our jobs with the same dedication that has made us the strong company we are today.

We believe this transaction will create significant shareholder value by expanding MPC’s footprint into key refining and midstream markets, as well as creating new opportunities for our retail segment. At the close of this transaction, expected in the second half of this year, MPC will have operations coast to coast and will be the largest refiner by capacity in the United States.

This transaction is a milestone in MPC’s 130-year history of providing the fuels and other products that make our modern lives possible. Please see this short video for additional information, and read the news release we published today for details of this exciting development.

Thank you for your continued hard work as we begin this next chapter in our company’s growth.

Sincerely,

Gary R. Heminger
Chairman and CEO

These forward-looking statements relate to, among other things, the proposed transaction between MPC and Andeavor (“ANDV”) and include expectations, estimates and projections concerning the business and operations, strategic initiatives and value creation plans of MPC. In accordance with “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, these statements are accompanied by cautionary language identifying important factors, though not necessarily all such factors, that could cause future outcomes to differ materially from those set forth in the forward-looking statements. You can identify forward-looking statements by words such as “anticipate,” “believe,” “could,” “design,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “imply,” “intend,” “may”, “objective,” “opportunity,” “outlook,” “plan,” “position,” “potential,” “predict,” “project,” “prospective,” “pursue,” “seek,” “should,” “strategy,” “target,” “would,” “will” or





other similar expressions that convey the uncertainty of future events or outcomes. Such forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond the company’s control and are difficult to predict. Factors that could cause MPC’s actual results to differ materially from those implied in the forward-looking statements include: the ability to complete the proposed transaction between MPC and ANDV on anticipated terms and timetable; the ability to obtain approval by the shareholders of ANDV and MPC related to the proposed transaction and the ability to satisfy various other conditions to the closing of the transaction contemplated by the merger agreement; the ability to obtain governmental approvals of the proposed transaction on the proposed terms and schedule, and any conditions imposed on the combined entity in connection with consummation of the proposed transaction; the risk that the cost savings and any other synergies from the proposed transaction may not be fully realized or may take longer to realize than expected; disruption from the proposed transaction making it more difficult to maintain relationships with customers, employees or suppliers; risks relating to any unforeseen liabilities of ANDV; future levels of revenues, refining and marketing margins, operating costs, retail gasoline and distillate margins, merchandise margins, income from operations, net income or earnings per share; the regional, national and worldwide availability and pricing of refined products, crude oil, natural gas, NGLs and other feedstocks; consumer demand for refined products; our ability to manage disruptions in credit markets or changes to our credit rating; future levels of capital, environmental or maintenance expenditures, general and administrative and other expenses; the success or timing of completion of ongoing or anticipated capital or maintenance projects; the reliability of processing units and other equipment; business strategies, growth opportunities and expected investment; MPC’s share repurchase authorizations, including the timing and amounts of any common stock repurchases; the adequacy of our capital resources and liquidity, including but not limited to, availability of sufficient cash flow to execute our business plan and to effect any share repurchases, including within the expected timeframe; the effect of restructuring or reorganization of business components; the potential effects of judicial or other proceedings on our business, financial condition, results of operations and cash flows; continued or further volatility in and/or degradation of general economic, market, industry or business conditions; compliance with federal and state environmental, economic, health and safety, energy and other policies and regulations, including the cost of compliance with the Renewable Fuel Standard, and/or enforcement actions initiated thereunder; the anticipated effects of actions of third parties such as competitors, activist investors or federal, foreign, state or local regulatory authorities or plaintiffs in litigation; the impact of adverse market conditions or other similar risks to those identified herein affecting MPLX; and the factors set forth under the heading “Risk Factors” in MPC’s and ANDV’s respective Annual Reports on Form 10-K for the year ended Dec. 31, 2017, filed with Securities and Exchange Commission (SEC).  We have based our forward-looking statements on our current expectations, estimates and projections about our 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 respective 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.
