Westinghouse confidentially files for US IPO

Westinghouse Electric, the nuclear reactor and fuel-services giant owned 51% by Brookfield and 49% by Cameco, confidentially submitted a draft S-1 registration statement to the SEC on July 31, 2026 for a proposed US initial public offering. Share count and price range are undetermined, and under the terms of a 2025 US government strategic partnership, Washington holds an option to take an 8% equity stake if Westinghouse's valuation reaches $30 billion.
