The global nuclear industry is entering a new era of growth, creating significant long-term investment opportunities.

The World Nuclear Association's (WNA) new inaugural module of the World Nuclear Investment Guide - available at https://t.co/0aupsjsiyp - is helping to bridge the gap between government commitments to nuclear energy, long-term project execution and investment opportunities. The guide provides investors, governments and industry with a shared understanding of risk, value and investment requirements across a rapidly expanding global nuclear market.

Cameco is proud to have contributed industry expertise to this guide and to support the Finance Summit at #Symposium2026.

[World Nuclear Association @WorldNuclear]

Delivering the ambition to at least triple global nuclear capacity by 2050 represents a $6 trillion investment opportunity across the global nuclear value chain.
