Astellas Wins OSI But Victory Comes At A Price

Japanese drugmaker Astellas Pharma's painstaking pursuit of OSI Pharmaceuticals is officially over. The victory came at a price, however, costing $4 billion, about $500 million more than Astellas' original hostile bid, launched in late February. That Astellas and OSI managed to find a path forward isn't surprising. Both companies had too much at stake not to see the merger come to fruition.
