TransAlta Announces Pricing of US$400 Million Senior Green Bond Offering

TransAlta Corporation is pleased to announce that it priced a public offering (“the Offering”) of US$400 million aggregate principal amount of its 7.750% senior notes due November 15, 2029, at an issue price equal to 100% of the principal amount of the notes, in an underwritten U.S. public offering. Including the gain on the corresponding interest rate hedges, the issuance equates to an effective yield of approximately 5.982%. Closing of the Offering is expected to occur on or about November 17, 2022.

TransAlta intends to use the net proceeds from the sale of the notes to repay C$100 million drawn on its credit facility and replace balance sheet cash used to fund the repayment in full of TransAlta’s 4.500% unsecured senior notes on November 15, 2022 and pay any related fees and expenses. We intend to allocate an amount equal to the net proceeds from this offering to finance or refinance, in part or in full, new and/or existing eligible green projects in accordance with our Green Bond Framework.
