Marathon Petroleum Corporation Provides Interim Second-Quarter 2013 Update

Marathon Petroleum Corporation

today announced that the company expects to report earnings in the range of $570 million to $600 million, or $1.75 to $1.85 per diluted share, for the second quarter of 2013, compared with earnings of $814 million, or $2.38 per diluted share, for the second quarter of 2012. Included in the second-quarter 2013 estimate are after-tax charges of approximately $39 million, or $0.12 per share, related to pension settlement expenses compared with approximately $53 million, or $0.15 per share, in the second quarter of 2012. Second-quarter 2013 Refining and Marketing segment results are expected to be negatively impacted in comparison to second quarter of 2012 by a number of factors, such as lower crude oil price differentials and product realizations compared to spot market values, which MPC believes were impacted by the Renewable Fuels Standard. The company will host a conference call on Aug. 1 at 10 a.m. EDT to provide an update on company operations and to discuss 2013 second-quarter financial results, which will be released earlier that day.
