TransAlta Corporation Provides Notice of Series E Preferred Shares Conversion Right and Announces Reset Dividend Rates

CALGARY, Aug. 31, 2017 /PRNewswire/ - TransAlta Corporation ("TransAlta" or the "Company") (TSX: TA; NYSE: TAC) announced today that it does not intend to exercise its right to redeem all or any part of the currently outstanding Cumulative Redeemable Rate Reset First Preferred Shares, Series E ("Series E Shares") (TSX: TA.PR.H) on September 30, 2017 (the "Conversion Date").

As a result, and subject to certain conditions set out in the prospectus supplement dated August 3, 2012 relating to the issuance of the Series E Shares, the holders of the Series E Shares will have the right to elect to convert all or any of their Series E Shares into Cumulative Redeemable Floating Rate First Preferred Shares, Series F of the Company ("Series F Shares") on the basis of one Series F Share for each Series E Share on the Conversion Date.

With respect to any Series E Shares that remain outstanding after September 30, 2017, holders thereof will be entitled to receive quarterly fixed cumulative preferential cash dividends, if, as and when declared by the Board of Directors of TransAlta.  The annual dividend rate for the Series E Shares for the five-year period from and including September 30, 2017 to but excluding September 30, 2022, will be 5.194%, being equal to the five-year Government of Canada bond yield of 1.544% determined as of today, plus 3.65%, in accordance with the terms of the Series E Shares.

With respect to any Series F Shares that may be issued on September 30, 2017, holders thereof will be entitled to receive quarterly floating rate cumulative preferential cash dividends, if, as and when declared by the Board of Directors of TransAlta. The annual dividend rate for the 3-month floating rate period from and including September 30, 2017 to but excluding December 31, 2017 will be 4.392%, being equal to the annual rate for the most recent auction of 90-day Government of Canada Treasury Bills of 0.742% plus 3.65%, in accordance with the terms of the Series F Shares (the "Floating Quarterly Dividend Rate").  The Floating Quarterly Dividend Rate will be reset every quarter.

As provided in the share conditions of the Series E Shares: (i) if TransAlta determines that there would remain outstanding immediately following the conversion, less than 1,000,000 Series E Shares, all remaining Series E Shares shall be converted automatically into Series F Shares on a one-for one basis effective September 30, 2017; or (ii) if TransAlta determines that there would remain outstanding immediately after the conversion, less than 1,000,000 Series F Shares, holders of Series E Shares shall not be entitled to convert their shares into Series F Shares on the Conversion Date.  There are currently 9,000,000 Series E Shares outstanding.

The Series E Shares are issued in "book entry only" form and must be purchased or transferred through a participant in the CDS depository service ("CDS Participant"). All rights of holders of Series E Shares must be exercised through CDS or the CDS Participant through which the Series E Shares are held. The deadline for the registered shareholder to provide notice of exercise of the right to convert Series E Shares into Series F Shares is 3:00 p.m. (MST) / 5:00 p.m. (EST) on September 15, 2017.  Any notices received after this deadline will not be valid. As such, holders of Series E Shares who wish to exercise their right to convert their shares should contact their broker or other intermediary for more information and it is recommended that this be done well in advance of the deadline in order to provide the broker or other intermediary with time to complete the necessary steps.

If TransAlta does not receive an election notice from a holder of Series E Shares during the time fixed therefor, then the Series E Shares shall be deemed not to have been converted (except in the case of an automatic conversion). Holders of the Series E Shares and the Series F Shares will have the opportunity to convert their shares again on September 30, 2022, and every five years thereafter as long as the shares remain outstanding.

The Toronto Stock Exchange (TSX) has conditionally approved the listing of the Series F Shares effective upon conversion.  Listing of the Series F Shares is subject to TransAlta fulfilling all the listing requirements of the TSX.
