This stock looks like a nice opportunity. I have been reading on Delaware corporate law and it seems that there quite a bit of protection for minority shareholders against low ball offers(Appraisal rights). This would be used if Icahn tried to cashout minority parties at less than $30.

In any event a tender for less than $30 right now would not have anyone tendering obviously
This means that if Icahn wants to merge this company with his own one he either must do another $30 tender again or buy the stock daily with a ever declining float which would drive the stock up(Specially if people realized what he is doing)
So this stock all comes down to the probability that Icahn will want to send his ownership from 80.8% to 90% in order to execute the merger. It comes down to how much a merger benefits him compared to no-merger
It seems much more likely he will want the merger instead of keeping the company as it is given all the costs of being a public company and the advantages that a merger might bring(Economies of scale, tax benefits)
The risk here is the he decides to buy a little bit of the stock every day for many months and executes the merger months from now. Then he can claim the valuation has changed and he doesn't have to pay $30 for the remaining shares . There is also risk that he won't try the merger and will just keep things they way they are right now. Seems unlikely to me, if he wanted to merge before why give up when you got almost 81%?
If I had to guess he will be buying some and then do another tender. Worst case scenario you are stuck with a company that Icahn feels that its worth at least $30 at 9 times earnings
In Sum
-He might do another tender at $30
-He will try to buy almost 50% of the float then force the merger(at $30 since less might trigger appraisal rights lawsuits)
-He will keep things as they are and you have to own a stock that Carl Icahn think its cheap. You will benefit from the board changes
Long looks good here
