cost airline National Air Services (NAS) is targeting an initial public offering (IPO) in 2012-2013 and eyes launching a foreign hub, most likely in Dubai, by early 2012, its CEO said Monday. NAS will launch an IPO after posting profits for two consecutive years, a main condition for going public, Simon Stewart told Reuters in a phone interview. “We will not be profitable by 2010. But we will break even or more than break even in 2011,” he said. Of the three locations being considered for the foreign hub, Dubai is the most likely choice, he said.
