UEX Corporation

UEX was a Saskatoon-based uranium explorer with a portfolio of 29 projects in the Athabasca Basin, five of them at the advanced resource stage in joint ventures with established miners. In June 2022, Uranium Energy Corp (UEC) agreed to acquire the company in an all-stock plan of arrangement, pitched as a move that would roughly double UEC's uranium resources and create the largest diversified North American–focused uranium company.
A wrinkle came in late July 2022, when Denison Mines tabled a competing offer that UEX's board deemed a "superior proposal." UEC exercised its right to match, and the deal held together. UEX securityholders approved it on August 15, the BC Supreme Court signed off on August 18, and the arrangement closed August 22, 2022. Shareholders received 0.090 of a UEC share for each UEX share held.
Following the close, UEX's common shares were delisted from the TSX and the company ceased to be a reporting issuer, folding into UEC. Its Athabasca assets — including its majority stake in the Christie Lake project and JV interests alongside partners like Cameco and Orano — now sit within UEC's portfolio.
