What is your reason? It just got 'good' results. They still need to bleed until they get FDA approval. Then look out for buyers. Then price agreements. There are other Bio-techs that actually got approvals and still could not find right partners or buyouts.
The US approval is guaranteed with these results for a $1 billion drug. This is a very attractive target for multiple companies so they can't wait around for the FDA approval & launch before making a bid.
