CALGARY, Alberta, July 31, 2026 (GLOBE NEWSWIRE) --

TransAlta Corporation (TransAlta or the Company) (TSX:TA) (NYSE:TAC) today reported its financial results for the second quarter ended June 30, 2026.

"TransAlta delivered strong operational performance across our portfolio in the second quarter, underlining our ability to generate reliable free cash flow from our diversified fleet despite a challenging Alberta market and reduced market volatility," said Joel Hunter, President and Chief Executive Officer of TransAlta.

"Our Alberta portfolio's hedging strategy and active optimization continued to generate realized prices well above spot prices, while environmental credits generated by our hydro and wind assets significantly offset our merchant gas fleet's carbon price compliance obligation. Our assets have performed well in the first half of the year, and we remain confident in our 2026 Outlook," added Mr. Hunter.

"This quarter, we realigned our executive team and I am confident that we have the right people and structure to execute our strategy. I am also very pleased with the continued advancement of our strategic priorities within the quarter, including the Centralia coal-to-gas conversion and our acquisition of new, high-quality, long-term contracted assets in Colorado. In Alberta, positive recent developments reinforce the momentum and collective commitment across government and industry to develop AI infrastructure and I am pleased with the continued progress on our project with CPP Investments and Brookfield," concluded Mr. Hunter.

Forward-looking statements are not facts, but only predictions and generally can be identified by the use of statements that include phrases such as "may", "will", "believe", "expect", "estimate", "anticipate", "intend", "plan", "forecast", "continue" or other similar words. In particular, this news release contains forward-looking statements about the timing of the closing of the Acquisition (as defined herein).

Forward-looking statements and future-oriented financial information in this news release are intended to provide the reader information about management's current expectations and plans and readers are cautioned that such information may not be appropriate for other purposes. Forward-looking statements are subject to important risks and uncertainties and are based on certain key assumptions. All forward-looking statements reflect TransAlta's beliefs and assumptions based on information available at the time the statements were made and as such are not guarantees of future performance. As actual results could vary significantly from the forward-looking statements, you should not put undue reliance on forward-looking statements and should not use future-oriented information or financial outlooks for anything other than their intended purpose. We do not update our forward-looking statements due to new information or future events, unless we are required to by law. For additional information on the assumptions made, and the risks and uncertainties which could cause actual results to differ from the anticipated results, refer to our most recent MD&A, which forms part of this news release, and the 2025 Annual Report, including the section titled "Governance and Risk Management" in our MD&A for the year ended December 31, 2025, filed under TransAlta's profile on SEDAR+ at www.sedarplus.ca and with the U.S. Securities and Exchange Commission at www.sec.gov
