Here are some interesting figures taken from the below linked seeking alpha article.
Assuming RGI develop only 20,000 sq ft of their new facility & receive only $5 a gram, they'll have annualised revenue of $45m based on the lower figure of 7 lb per machine & 6 crops. In the below table there are 2 companies with similar revenues, Tilray with a market cap of $13.3 billion and Canntrust with a market cap of $811 million. Even Emblem with revenues of $9m has a market cap of $143m.
For sure many of these companies are valued on future (not past) earnings, having said that, RGI isn't going to stop at 20,000 sq ft either & also has 2 big fresh food deals.
