Bristol/Medarex: A Transformational Acquisition Rooted In Collaboration

Bristol's $2.4 billion buyout of Medarex in 2009 yielded value equivalent or greater to that realized in larger M&A transactions signed that year, such as Pfizer/Wyeth, Merck/Schering-Plough and Roche/Genentech. The deal made BMS a leader in immuno-oncology and by most accounts is the highlight of the pharma's "string of pearls" strategy.
