RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RTO ProcessRTOs seem to be the most popular method for Cannabis companies to go public in Canada. Aurora Canabis went public through an RTO with a mining company in December 2014. Other companies have also done RTO's with shell companies aka Capital Pool Companies or CPC.
In both cases, the private Canabis company uses the public company as a vehicle to go public even though the public company brings nothing of value to the company other than being publicly listed.
The BEVO Sun Pharm merger is the only one I know of where both companies brought significant value to the table. The merged company Zenabis is greater than the sum of its parts and years closer to being a major player in the industry. There may be others that I am not aware of, I am by no means an expert in the Cannabis industry.
