BioRocks, I think that is a very reasonable scenario and makes a lot of sense in Denner taking the risk off the table, making some good money, getting Ariad back to pre-2013 crash levels and moving on.
Certainly, it is in Denner's DNA to "hit and run" vs. become an ultra long term investor. Also, that level makes sense in giving the new management people the opportunity to cash in as well as it would be worth their time and career interruptions to be rewarded in less than a year of hard work.
It would be a "win-win" for everyone.
