Cameco Announces Bought Deal Offering of Common Shares
Saskatoon, Saskatchewan, Canada, February 18, 2009 . . . . . . . . . . . . . .
Cameco Corporation (TSX: CCO; NYSE: CCJ) today announced that it has entered into an agreement with a syndicate of underwriters, led by BMO Capital Markets and RBC Capital Markets, who have agreed to purchase 23,188,400 Cameco common shares on a bought deal basis at a price of C$17.25 per share for sale to the public, primarily in Canada and the United States. Cameco has also granted to the underwriters an over-allotment option to purchase, on the same terms, up to a further 3,478,000 common shares. The option is exercisable at any time, in whole or in part, up to 30 days after the closing, which is scheduled to occur on March 5, 2009.
The offering is expected to provide Cameco with gross proceeds of approximately C$400 million (or C$460 million if the over-allotment option is exercised in full). Cameco intends to use the net proceeds of the offering to strengthen its capital position and enhance its financial flexibility to allow it to take advantage of opportunities that may emerge from the current industry environment, and for general corporate purposes.
The common shares will be offered by way of a short form prospectus in all of the provinces and territories of Canada and will be offered in the United States pursuant to a registration statement filed under the multi-jurisdictional disclosure system, and may also be offered on a private placement basis in certain jurisdictions outside of Canada and the United States pursuant to applicable prospectus exemptions. A registration statement relating to these securities has been filed with the United States Securities and Exchange Commission but has not yet become effective. The securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these common shares in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
The offering is subject to certain customary terms and conditions, including the approval of the Toronto Stock Exchange. A copy of the prospectus relating to the securities may be obtained in Canada from: BMO Capital Markets, Distribution Department, 1 First Canadian Place, B2 Level, Toronto, Ontario, M5X 1H3 (tel: 416-363-6996 x224) or from RBC Capital Markets, Attention: Distribution Centre, 277 Front St. W., 5th Floor, Toronto, Ontario M5H 2X4 (tel: 416-842-5349), or in the United States from BMO Capital Markets Corp., Attention: Lori Begley, 3 Times Square, 27th Floor, New York, New York, 10036 (tel: 212-885-4039) or from RBC Capital Markets Corporation, Attention: Prospectus Department, Three World Financial Centre, 200 Vesey Street, 8th Floor, New York, NY 10281-8098 (tel: 212-428-6670).
