Sunoco to Exit Refining and Conduct Strategic Review of the Company

Sunoco, Inc. (NYSE: SUN) announced today that it plans to exit its refining business and has begun a process to sell its refineries located in Philadelphia and Marcus Hook, Penn. Sunoco also announced that it is conducting a comprehensive strategic review of the company to determine the best way to deliver value to shareholders, including how best to utilize the company’s strong cash position and maximize the potential for Sunoco’s logistics and retail businesses. Credit Suisse Securities (USA) LLC has been retained to assist in the review process.

Sunoco will pursue all options to sell its refineries, but if a suitable transaction cannot be implemented, the company intends to idle the main processing units at the facilities in July 2012.

"We have made progress in increasing the efficiency of our refineries over the last several years, but given the unacceptable financial performance of these assets, it is clear that it is in the best interests of shareholders to exit this business and focus on our profitable retail and logistics businesses which have higher returns, growth potential, and provide steady, ratable cash flow,” said Lynn L. Elsenhans, Sunoco’s chairman and chief executive officer.

Together with the separation of SunCoke Energy and the sale of the chemicals business, Sunoco’s decision to exit refining marks a fundamental shift away from manufacturing that will re-position the company.

In connection with the decision to exit refining, the company expects to record a pretax noncash charge of between $1.9 billion and $2.2 billion in the third quarter of 2011 related to impairment of the plant and equipment in the refineries. In the event the processing units are idled, additional pretax charges of up to $500 million, primarily related to contract terminations, staffing costs and severance, may be incurred. Most of these costs would be paid over a period of approximately one year. Additionally, upon the sale of the refineries or idling of the main processing units, the company expects to record a pretax gain related to the liquidation of all of its crude oil and a significant portion of its refined product inventories totaling approximately $2 billion at current market prices. The actual amount of this pretax gain will depend upon the market value of crude and refined products and the volumes on hand at the time of liquidation.

Regarding the strategic review process, Elsenhans said, "With SunCoke’s recent initial public offering, our complete exit from the chemicals business, and our plan to exit refining, we have an opportunity to take a fresh look at all aspects of the company and gain added perspective on how best to use our cash and maximize the potential for our strong retail and logistics businesses with a view toward creating value for our shareholders.”

Sunoco has not set a timetable for completing the strategic review process, and will provide updates as appropriate.

Share repurchase

Sunoco also announced that it has substantially completed the $500 million share repurchase program that was announced on August 9, 2011. The share repurchases were funded by the company's available cash reserves and resulted in the repurchase of 13,140,586 shares at an average price of $34.74 per share. As of September 6, 2011, the company has approximately 108 million shares of common stock outstanding.
