5N Plus Inc. announced that David Langlois will join the company as chief financial officer, effective Nov. 23, 2009.

Prior to joining 5N Plus, Langlois, a chartered accountant, was the vice president of corporate accounting and information management at National Bank Financial Inc., one of the top investment dealers in Canada. He succeeds Christian Dupont, who will be leaving 5N Plus to pursue other interests.

“We are pleased to welcome David Langlois, who brings a wealth of experience from the banking, financial and auditing sectors” said Jacques L’Ecuyer, president and CEO of 5N Plus. “We expect his contribution to help us execute our growth strategy, which calls for both organic and acquisition-related initiatives. I would like to thank Christian Dupont for his work as CFO during the last two years, and in particular for his efforts during 5N Plus’ successful initial public offering."
