Re: PBM consolidation UNH acquires CRTX for $12.8B: http://finance.yahoo.com/news/unitedhealth-group-buy-catamaran-12-102329444.html The merged company will be roughly as large in the PBM arena as the current #2 player, CVS. (ESRX is #1.) p.s. I didn’t put this deal in the Biotech Buyouts table because I don’t consider PBMs biotechs.
