Those number are usually very outdated but let's use those numbers for now.
Typically reverse mergers the new company ends up with 90-95% of the shell.
So let's say 5 million shares OS now and that the Israelis buying GBNW are fair guys and will only own 90% of new company.
That would give us 55 million shares outstanding after the merger. The PR referenced a value for the new company of 22-28 million dollars. 55 million shares OS with a market cap of 28 million, gives a share price of .50 per share fair value.
