I do not see any story about Merck buying Idenix. There were many stories about 2 years ago when Pharmasett was bought for 11 b, followed by Inhibitex for 2.5B. Idenix was the only company left with "nucleotide" technology. The buyout never happened and those rumors went away. I do see the Baupost Group has steadily increased its ownership with the latest release of the outsized increase in share purchase from 20% to 27% with the next biggest shareholder being Novartis with 25% ownership. Bain Capital is the next largest owner at 10%. I do not even see how Merck could acquire this company if it wanted to. There are not enough "open" shares. We will see, because something IS GOING ON.
