NexGen Energy launches dual offering for Rook I project development

NexGen Energy Ltd. is launching concurrent offerings: a bought deal of common shares in Canada and the United States, and an offering of common shares (settled as CDIs) in Australia and other jurisdictions. The Canadian and U.S. offering targets gross proceeds of $[•] and will be underwritten by Merrill Lynch Canada Inc. and other North American underwriters. The Australian offering of [•] common shares, settled as CDIs, at an offering price of A$[•] per CDI, also seeks aggregate gross proceeds of $[•], with [•] acting as the Australian underwriter. Both offerings aim to raise total gross proceeds of $[•].

The company plans to use the net proceeds, estimated at $[•] from the Australian offering and $[•] from the North American offering, to advance engineering for the Rook I Project ($[•]), fund pre-production capital costs ($[•]), and for general corporate purposes ($[•]).

The offering price was determined through arm's-length negotiations, referencing the prevailing market prices of NexGen's common shares on the TSX and NYSE, and its CDIs on the ASX. Trading data from September 30, 2025, shows common shares closing at $12.46 on the TSX, US$8.95 on the NYSE, and CDIs at A$13.79 on the ASX.

The completion of both offerings is not conditional upon each other. NexGen anticipates receiving a CNSC license in 2026, though the timing is uncertain. The company has no material subsidiaries and its head office is in Vancouver, British Columbia, Canada.
