TransAlta Announces Closing of $350 Million Bought Deal Offering of Common Shares
CALGARY, Alberta (June 9, 2026)
TransAlta Corporation (TransAlta or the Company) (TSX: TA) (NYSE: TAC) is pleased to announce that it has closed its previously announced bought deal offering (the Offering) of common shares.
Pursuant to the Offering, TransAlta issued a total of 18,230,000 common shares (the Offered Shares) at a price of $19.20 per share (the Offering Price) for total gross proceeds of approximately $350 million.
The Offered Shares were offered and sold through a syndicate of underwriters led by CIBC Capital Markets and RBC Capital Markets.
TransAlta intends to use the net proceeds of the Offering to fund the cash purchase price of its previously announced acquisition (the Acquisition) of two new natural gas-fired peaking facilities totaling 318 MW near Denver, Colorado. The Acquisition is expected to close early in the fourth quarter of 2026, subject to the satisfaction of certain closing conditions, including receipt of regulatory approvals.
The underwriters also have an option to purchase up to an additional 2,734,500 common shares at the Offering Price, exercisable for a period of 30 days following the closing of the Offering, for potential additional gross proceeds to TransAlta of approximately $52,502,400.
If the Acquisition is not completed, the Company intends to use the net proceeds from the Offering to finance future growth opportunities including acquisitions, finance its capital development expenditures, reduce its outstanding indebtedness or for other general corporate purposes.
For additional information regarding the Acquisition and the Offering, refer to the Company’s news release dated June 3, 2026, available under TransAlta’s profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.
This news release does not constitute an offer to sell or the solicitation of an offer to buy any securities of TransAlta.
