Marathon Petroleum Corporation Increases Dividend 28 Percent

FINDLAY, Ohio, July 29, 2015 - Marathon Petroleum Corporation MPC announced today that its board of directors declared a dividend of $0.32 per share on common stock, a 28 percent increase from the $0.25 per-share dividend in the first quarter of 2015, after adjusting to reflect the two-for-one stock split that occurred during the second quarter. The dividend is payable Sept. 10, 2015, to shareholders of record as of the close of business Aug. 19, 2015.

"This is the fifth increase in MPC's dividend and represents a 34 percent compounded annual growth rate from the dividend level established at the time MPC became a standalone public company," said President and Chief Executive Officer Gary R. Heminger. "This substantial increase demonstrates our ongoing commitment to our shareholders to share the success of the business with them as we also continue to invest in future growth."

On July 30, MPC will provide an update on its 2015 second-quarter results through an earnings news release, to be followed by a conference call scheduled for 10 a.m. EDT that day.
