You and I have broached this subject via PM if I recall??
Yep. The thing is I would not be surprised if they roll the lab division into the dental division. But who knows. They are an absolute monstrosity. $13 billion market cap.
As far as getting bought or merged, while you never know but their stock is trading in the mid $150's per share so very unlikely. I would look for them to make more acquisitions and throw their weight around. Personally dislike a lot of the execs there, but they know what they are doing.
Also note that lab biz is minuscule compared to the other stuff. And if anyone thinks for a minute that when they buy a company they intend to keep all the staff, I've got some WMD's in Iraq to sell you. Smaller acquisitions are made because it is cheaper to buy the company out of the way. Their M&A team is aggressive and they have the cash to back it up.
As with everything, this should all be taken with a grain of salt because you never know what is really going on behind the curtain. Enron was a great buy at one point too.
