To be conservative expect 30 million shares by then, and I use the term conservative loosely.
To be conservative about after interim analysis, use $75 million market cap. That is not worst case, be real.
We don't know what year phase 3 will be complete, too early to say. Yes by then investors may be in a totally different frame of mind, so then $300 million, why not?
So if the company makes it to end of phase 3, a buy below 50 cents could work out very well, but not a done deal
