SXC Health to buy Catalyst in $4B-plus deal

SXC Health Solutions Corp. plans to buy fellow pharmacy benefits manger Catalyst Health Solutions Inc. in a deal worth more than $4 billion, less than a month after competitor Express Scripts Inc. closed a $29.1 billion acquisition. The combined company will be headquartered in Lisle, Ill., which is where SXC is based, and will have an annual prescription volume of more than 200 million. In contrast, the combination of Express Scripts and Medco Health Solutions Inc. should fill about 1.5 billion prescriptions a year, based on 2011 figures.
