A reverse takeover or reverse merger (reverse IPO) is the acquisition of a public company by a private company so that the private company can bypass the lengthy and complex process of going public. The transaction typically requires reorganization of capitalization of the acquiring company. In a reverse takeover, shareholders of the private company purchase control of the public shell company and then merge it with the private company. The publicly traded corporation is called a “shell” since all that exists of the original company is its organizational structure. The private company shareholders receive a substantial majority of the shares of the public company and control of its board of directors. In August 2011, through a reverse takeover Greentech Energy Systems and the Italian GWM RE were merged.
