OK, you are nervous. Welcome to IMSC! Everyone is nervous. Nobody knows anything for sure. BUT, read Percy's sticky at the top of the message thread. I think he carves out a good thesis for why a BUY OUT or even a BUY IN is in progress.
But once again, nothing is certain except death and taxes. BUT "taxes" has a role in this...we know the TSA is searching for answers and greatly over-extending the use of the common swab in its ETD layer. That is a huge "tax" on passenger thru-put. Couple that to Congress cutting TSA's budget in 2012 and you have the makings for Congress to do something about it if they can't lay the blame on somebody else.
What can be done? Deeper automation in passenger checkpoint, carryon and baggage. Enter ISC with NON-CONTACT ETD solutions to address/tackle that opportunity. THAT is why we are here. AND IMO, that is why some company, likely in NE is going to take out ISC. The Take Out "sidewalls" range from a competitors POV of $80M to ISC shareholders POV of $700+M.
