The other two companies, Aurora and Aphira, fund their operations by printing shares and devaluing current investors. I consider them to be the spam coin equivalent of the two larger companies. There are dozens of others, these are just four of the largest I consider to be the biggest players.
I should have read all of this before trying for 10 minutes to understand those numbers and how and why they've grown 94.75% in 3 months and 44.17% in six.

But this is really a weird strategy, they are diluting their own shares if so and most of the money goes on acquisitions...
In January 2018, Aphria agreed to take over Broken Coast Cannabis, for $230 million in cash and stock
January 2018, Aphria agreed to buy Nuuvera, a Brampton-based cannabis company, for $826 million
In July 2018, Aphria announced it would acquire several South American cannabis companies for about $200 million
and this is only from wiki which sucks at financial stuff.
I really wonder who is putting that money in, 4 billion investment in a company based in a market that
might reach 32 billion by 2022 is a bit of overkill.
