Sunoco, Inc.

took another step today toward the previously announced separation of its metallurgical cokemaking business from its other businesses with the filing by its subsidiary, SunCoke Energy, Inc., of a registration statement with the Securities and Exchange Commission for a proposed initial public offering of shares of SunCoke's common stock. The number of shares to be offered and the price range for the offering have not yet been determined. The initial public offering is anticipated to be completed in 2011. At the completion of the proposed offering, Sunoco will continue to own more than 80 percent of the outstanding common stock of SunCoke.
