Shareholders of ATK and Orbital Sciences Corporation voted Tuesday to approve a merger of the two companies, which will allow the merger to close early next month. In separate votes, shareholders of the two companies approved a deal announced last April to merger Orbital with ATK's aerospace and defense divisions. The new company, to be named Orbital ATK Inc., will start operations under that name on February 10, trading on the New York Stock Exchange under the ticker symbol OA. Prior to completing the merger, ATK will spin off its sporting goods division into a separate company, Vista Outdoor.
