because ISOLF investors are going to realize that the company they bought stock in, all of a sudden, is going to have twice the number of O/S than they thought it had when they first bought the shares
and because acquisitions made when the ISOLF stock price was in the $7 to $10 stock price no longer make sense when 10 times more ISOLF stock has to be issued to the sellers
and finally, because the former owners of those companies acquired are going to sell most of their ISOLF shares into the market once the lock up agreements are done with, which are every month. If they wanted to keep the shares then they never would have sold their companies
