Bristol-Myers Squibb
In July 2012, Bristol-Myers Squibb announced it would acquire Amylin Pharmaceuticals for $5.3 billion. As part of the acquisition, AstraZeneca made a $3.4 billion cash payment to make Amylin a wholly owned subsidiary within the existing BMS/AZ joint venture in diabetes. In April 2013, Bristol-Myers Squibb announced it would close Amylin's San Diego operations by the end of 2014 and merge the Amylin manufacturing facility in West Chester, Ohio and all field-based sales personnel into Bristol-Myers Squibb operations.
