Cameco's 49% stake in Westinghouse could be revalued as Westinghouse builds a combined AP1000-AP300 reactor platform rather than a standalone SMR. Under APX platform agreements, Amentum will help win NRC approval for the AP300 and strengthen execution for gigawatt reactors at scale. Tying the proven AP1000 supply chain, workforce and engineering to the AP300 should improve licensing odds, shorten supply-chain buildout and strengthen EPC capability, a strategy linked to Westinghouse's IPO push. x.com
