Stillwater Announces That Its Majority Stockholder Has Exited

BILLINGS, MT--(Marketwire - December 13, 2010) - STILLWATER MINING COMPANY (NYSE: SWC) today announced the closing of two separate secondary offerings by its majority stockholder, Norimet Limited ("Norimet" or the "selling stockholder"), a wholly-owned subsidiary of Russian nickel producer, MMC Norilsk Nickel. In total, Norimet has sold its entire 49.8 million share interest in Stillwater. The sale of 46.0 million shares of Stillwater common stock closed today, of which 37.0 million shares were sold to the public at a public offering price of $19.50 per share. Also in connection with this offering, today the underwriters exercised their over-allotment option in full to purchase an additional 3.8 million shares. Norimet sold the remaining 9.0 million shares to UBS Securities LLC in connection with the closing of a previously announced public offering by UBS AG of Mandatorily Exchangeable Notes due 2012. Upon the closing of the over-allotment option later this week, Norimet will no longer own any shares of Stillwater's common stock. Stillwater Mining Company is not receiving proceeds from either of the offerings by Norimet.

Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, UBS Securities LLC and VTB Capital PLC acted as joint bookrunning managers for the underwritten public offering of the common stock. VTB Capital PLC is not a U.S. registered broker-dealer, and therefore, to the extent that it effected any sales of shares of the common stock in the United States, such sales were executed through one or more U.S. registered broker-dealers, which may be affiliates of VTB Capital PLC, to the extent required by applicable U.S. securities laws and regulations. A copy of the prospectus supplement and base prospectus relating to the underwritten public offering of the common stock may be obtained by contacting: Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, New York, 10010-3629 (800-221-1037), J.P.
