Terrestrial Energy is developing for near‑term commercial operation, a zero‑emissions cogeneration plant for a global industry using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative, small and modular plant design.

Over the last 5 years, the company has recognized the exceptional and unmatched opportunities in U.S. markets created by the policies of the U.S. Federal and state governments, and by the actions of the U.S. industrial private sector, including its world‑leading IT sector developing AI commercial products. The company recognizes that its path to business success and likely sole path to success is to wholly align with the U.S. market as a U.S. company, and effect all the organizational changes necessary to achieve this alignment.

In pursuit of this objective, Terrestrial Energy initiated a transaction to legally redomicile the business to the U.S. in 2023, which it completed in April 2024, with 100% shareholder support. This transaction was the first step in its U.S. domiciliation strategy. The company is currently completing a transaction to secure a U.S. exchange (NASDAQ) public stock listing, which is expected to secure the capital resources necessary to complete its U.S. domiciliation as well as execute on its business plan focused on the U.S. market.
