Biotech Values

[Biowatch]

You have to keep in mind that some wouldn't be willing to merge or be bought out.
Acquire other companies, yes. Sell themselves to a larger company, no.

I think VRTX won't merge because Joshua Berger is happy to be a main feature there. However, money talks.
I suspect that BIIB has been solo for so long that it wouldn't want and doesn't need to merge.
TEVA seems too big in its own country to become second fiddle to someone elsewhere.
