Reverse Mergers in Biopharma

by | Jun 13, 2019

Reverse mergers have been a relatively quick method for companies to gain a public listing as an alternative to IPOs. A private company looking to go public merges with a company that is already publicly traded and changes the ticker symbol. Technically, the public company is acquiring the private company, hence the ‘reverse’ part. Also, it’s not uncommon to see public companies outside of the life sciences space on one side of the deal. Following a conversation over on Twitter (thanks, @syinvesting), we used the DealForma deals database to generate a quick list of 91 reverse mergers with biotechnology, medical device, and diagnostics companies since 2008.
