TransAlta Corporation reports that its subsidiary, TransAlta Centralia Generation LLC, has received an order from the U.S. Department of Energy requiring Centralia Unit 2 in Washington State to remain available for operation for an additional 90 days, until September 13, 2026. The company states it will comply with the order and continue working with the Department of Energy and the Washington state government in relation to this directive.

TransAlta Corporation closed a bought deal common share offering, issuing 18,230,000 shares at $19.20 per share for total gross proceeds of approximately $350 million. The shares were sold through a syndicate of underwriters led by CIBC Capital Markets and RBC Capital Markets.

TransAlta intends to use the net proceeds to fund the cash purchase price of its planned acquisition of two natural gas‑fired peaking facilities totaling 318 MW near Denver, Colorado, which is expected to close early in the fourth quarter of 2026, subject to regulatory approvals and other conditions. Underwriters hold a 30‑day option to buy up to an additional 2,734,500 shares for potential extra gross proceeds of about $52,502,400, and if the acquisition does not close, the company expects to redirect proceeds to other growth opportunities, capital projects, debt reduction or general corporate purposes.
