It's hard to say what the ramifications of a buyout would be for shareholders without knowing the terms. Easiest scenario is someone buys the whole operation. Then we'd get an agreed upon amount per share based loosely on commercial potential and the PPS at the time.
PPS at the time would likely be based on the specifics of the contract(s) and/or licensing agreement(s) signed. I agree with the prevailing opinion here that, at least from a mathematical standpoint, it wouldn't take much to get to a buck.
