Stillwater Mining Company Prices Offering of $345.00 Million of Convertible Senior Notes

BILLINGS, MT--(Marketwire - Oct 11, 2012) - STILLWATER MINING COMPANY (NYSE: SWC) (TSX: SWC.U) (the "Company") announced today that it has priced its previously announced offering of $345.00 million aggregate principal amount of 1.75% convertible senior notes due 2032 (the "notes"). The Company has also granted the underwriters of the notes a 30-day over-allotment option to purchase up to an additional $51.75 million aggregate principal amount of the notes (subject to certain limitations), solely to cover over-allotments.

The notes will be convertible, under certain circumstances and during certain periods, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, based on an initial base conversion rate for the notes of 60.4961 shares of the Company's common stock per $1,000 principal amount of notes (which is equivalent to an initial base conversion price of $16.53 per share of common stock and represents an approximately 50.0% conversion premium over the closing sale price of the Company's common stock on October 11, 2012, which was $11.02 per share) and an initial incremental share factor of 30.2481. If the price of the Company's common stock exceeds the base conversion price during specified periods applicable to conversion, holders will receive additional shares of the Company's common stock upon conversion, as determined based on the incremental share factor. In addition, the base conversion rate, base conversion price and incremental share factor will be subject to customary anti-dilution adjustments upon occurrence of certain events, such as distributions of dividends or stock splits. The offering is expected to close on October 17, 2012, subject to satisfaction of customary closing conditions.

On or after October 20, 2019, the Company may redeem the notes, in whole or in part, for cash. Holders may require the Company to repurchase for cash all or part of their notes on each of October 15, 2019, October 15, 2024 and October 15, 2029.

The notes will mature on October 15, 2032, unless earlier converted, redeemed or repurchased. The notes will bear interest at a rate of 1.75% per annum, which will be payable semi-annually in arrears on each April 15 and October 15 of each year beginning on April 15, 2013.

The Company intends to use the net proceeds from the offering to repay amounts that may come due under the Company's outstanding 1.875% convertible debentures in March 2013, and any additional proceeds may be used for general corporate purposes.
