Good question Stocktester. My take.......
It isn't gonna happen. The game here with GRBT and other "sister" companies (most all morphed from the old Homeland Security stock) is to sell each other shell companies, giving each convertible notes, conv. preferreds, 6 mo. restricted common, or just plain 'ol free trading stock in the other. Case in point:
Homeland Security screwed a lot of people with their stock selling scam with the CyberTracker device. When Homeland played out, they moved the CyberTracker into a new NV shell and it was sold to GRBT, who then GRBT sold it to WTCT for stock in WTCT. Riley, an officer, got stock in GRBT for the shell, now GRBT owns stock (to sell at some point) of WTCT.
A merger of the two might not be a wise thing to do.
Of course, both have the the other income stream of selling stock to financial "partners" on the cheap for cash. I would bet money that GRBT or and other pink, gets a kickback from the financial partners somehow. (Often these sales go down at huge discount to the current pps....sometimes at or below par value)
