Centene Corporation Acquires AirLogix, Inc.; Transaction Expands Specialty Platform to Include Disease Management Services

ST. LOUIS--(BUSINESS WIRE)--July 21, 2005--Centene Corporation (NYSE: CNC) today announced that it has acquired AirLogix, Inc., an industry leader in respiratory disease management. The acquisition of AirLogix's disease management capabilities will further enhance Centene's suite of specialty services, which is managed by CenCorp Health Solutions, a wholly owned subsidiary.

Under the terms of the agreement, Centene paid approximately $35 million in cash for AirLogix. The consideration was sourced from Centene's $100 million revolving credit agreement. The deal provides for additional consideration of up to $5 million based on achieving certain performance criteria.

Michael F. Neidorff, Chairman and Chief Executive Officer of Centene Corporation, stated, "The acquisition of AirLogix reflects our ongoing strategy to build a multi-line healthcare enterprise that significantly demonstrates the ability to effectively and consistently manage costs. The success of Centene's Margin Protection Program(TM) and our expansion into disease management, which combines Medicaid and commercial recipients, will continue to provide predictable outcomes and control of healthcare costs on a sustainable and long-term basis. AirLogix's disease management experience, combined with our financial strength, will allow us to better serve our expanding SSI membership and support AirLogix's existing customer base."

Susan B. Riley, Chief Executive Officer of AirLogix, added, "We are very enthusiastic about this combination. We believe it will provide us with additional resources to enhance our capabilities to assist consumers to promote behavior modification, better manage their diseases and enrich their overall quality of life. We share Centene's focus on customer service and the belief that healthcare takes place locally in the community. We look forward to integrating our experience of managing health concerns such as chronic obstructive pulmonary disease and asthma."

Centene estimates that this acquisition will initially generate annual revenues of approximately $18 million. The earnings impact from the transaction is expected to be nominal in 2005.
