A reverse merger (often known as a reverse takeover or reverse IPO) is a way for private companies to go public, normally through a more convenient, shorter, and less expensive process. A conventional initial public offering (IPO) is more complicated and expensive, as private companies seek the services of an investment bank to underwrite as well as issue shares of the soon-to-be public company. Besides filing the regulatory documents – and assisting authorities review the deal – the bank can also help to establish desire for the stock and provide suggestions on suitable initial pricing.
