NexGen Energy (ASX:NXG) will conduct an equity financing round, via a CA$400 million bought deal offering as well as a concurrent AU$400 million offering in Australia, according to a Thursday Australian bourse filing.

The firm entered an agreement with a syndicate of underwriters in North America led by Merrill Lynch Canada, under which the underwriters agreed to buy on a bought-deal basis 33,112,583 common shares of the firm at a price of CA$12.08 per common share for gross proceeds of around CA$400 million.

It also signed an underwriting agreement with Aitken Mount Capital Partners, under which Aitken agreed to fully underwrite an offering of 30,534,351 common shares in the capital of the firm, to be settled in the form of Australian CHESS depositary interests for gross proceeds of around AU$400 million.

The offering is expected to close on or about Oct. 15, and is subject to the receipt of required regulatory approvals, including conditional acceptance of the Toronto Stock Exchange as well as approval by the New York Stock Exchange.

It will use the net proceeds to progress engineering of the Rook I uranium project in Canada, for Rook I preproduction capital costs, and for general corporate purposes.
