In the penny world shells are gold. There is no reason at all to think Henry would ever combine 2 into 1. The more I think about this, if he were to do that, he'd be an even worse business man than I've been busting his cojones about. Rather than buying a new shell, you just issue new shares. IMO the value of a new shell to him is about diversifying risk.
SK - licensing
PJ - Internet pot commerce
AV - some lab related business...
If the government shuts down any one business, or they get sued, or Murphy's Law happens... It doesn't shut down the whole operation. Another value point of a new shell is that it makes it so much easier to sell/spinoff the different arms of his businesses if they are already separate.
