Calgary, Alberta (November 30, 2011) – TransAlta Corporation (TSX:TA) (NYSE:TAC) today announced it has completed its public offering of 11,000,000 Cumulative Redeemable Rate Reset First Preferred Shares, Series C (the “Series C Shares”) at a price of $25.00 per Series C Share.

The offering, previously announced on November 22, 2011, resulted in gross proceeds to TransAlta of $275 million.

TransAlta may invest funds that it does not immediately require in short-term marketable debt securities.

The Series C Shares were offered to the Canadian public through a syndicate of underwriters led by CIBC World Markets Inc., RBC Capital Markets and Scotia Capital Inc. by way of a prospectus supplement that was filed with securities regulatory authorities in Canada under TransAlta’s short form base shelf prospectus dated November 15, 2011.

Holders of Series C Shares are entitled to receive a cumulative quarterly fixed dividend yielding 4.60% annually for the initial period ending June 30, 2017. Thereafter, the dividend rate will be reset every five years at a rate equal to the 5-year Government of Canada bond yield plus 3.10%. Holders of Series C Shares will have the right, at their option, to convert their shares into Cumulative Rate Reset First Preferred Shares, Series D (the “Series D Shares”), subject to certain conditions, on June 30, 2017 and on June 30 every five years thereafter. Holders of Series D Shares will be entitled to receive cumulative quarterly floating dividends at a rate equal to the three-month Government of Canada Treasury Bill yield plus 3.10%.
