One way to give info w/o giving specifics could be if PBLS took a "Wheel of Fortune" contestant point of view with their announcements. Instead of saying we bought Best Jets, say we are in the process of buying a major private jet company in order to...blah, blah, blah. That way, investors have a little to chew on and can speculate to their heart's content over which company PBLS is buying. Of course, that's assuming investors don't call each of the major private jet companies to find out, if in fact, PBLS is buying them out. *LOL*.
Then once official (meaning the bought out company has told their employees, other processes have taken place), they can give specifics.
