I think most definitely you are lowballing, but who am I to say. Even at your price target of $4/share, it would only be trading at 5-6 times EBITDA. If you assume actual earnings are 3-4 x's less that EBITDA as a percentage, $4/share would mean Exousia is trading at a 15-24 times multiple. And even this would be too low considering the growth rate and assuming EBITDA is as low as you subscribe.

Bottom line is I believe $4/share is more than plausible should Exousia attain $100M in revs. And furthermore, Im confident they will considering the quality of product and considering they only have to achieve less than 1% marketshare which is more than attainable.
