Acquisition of BP’s Texas City Refinery and Related Logistics and Marketing Assets October 8, 2012 Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the federal securities laws. These forwardlooking statements relate to, among other things, MPC’s current expectations, estimates and projections concerning MPC’s business and operations and the business and operations proposed to be acquired from BP, which we refer to as the BP Texas City assets. You can identify forward-looking statements by words such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “project,” “could,” “may,” “should,” “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 actual results to differ materially from those in the forward-looking statements include: our ability to successfully complete the acquisition of the BP Texas City assets, including, without limitation, the receipt of regulatory approvals and the satisfaction of other customary closing conditions; our ability to successfully integrate the BP Texas City assets into our operations; our ability to achieve fully the strategic and financial objectives related to the proposed acquisition of the BP Texas City assets, including the acquisition being accretive to our earnings; and unexpected costs or liabilities that may arise from the acquisition ownership, or operation of, the BP Texas City assets; volatility in and/or degradation of market and industry conditions; the availability and pricing of crude oil and other feedstocks; slower growth in domestic and Canadian crude supply; completion of pipeline capacity to areas outside the U.S. Midwest; consumer demand for refined products; changes in governmental regulations; transportation logistics; the availability of materials and labor, delays in obtaining necessary third-party approvals, and other risks customary to construction projects; the reliability of processing units and other equipment; our ability to successfully implement growth opportunities and the integration of acquired assets; other risk factors inherent to our industry; and the factors set forth under the heading “Risk Factors” in MPC’s Annual Report on Form 10-K for the year ended December 31, 2011 filed with the SEC. In addition, the forward-looking statements included herein could be affected by general domestic and international economic and political conditions. Unpredictable or unknown factors not discussed here or in MPC’s Form 10-K could also have material adverse effects on forward-looking statements.
