Quiksilver reports the sale of its snowboard manufacturing operations to Extreme Holdings for an undisclosed amount of cash, as part of a profit improvement plan announced last May. The operations consist of Mervin Manufacturing and its Gnu and Lib Tech brands. Extreme Holdings is described as a company “advised” by Altamont Capital Partners, the American private equity company that recently bought Dakine from Billabong, but made an unsuccessful bid for the rest of Billabong. Mervin, which had sales of about $32 million in the latest 12-month period, will continue to make Roxy snowboards under a separate license agreement.
