Conifer Health Solutions to Acquire InforMed Health Care Solutions

Enhances offerings to successfully shift healthcare organizations to value-based healthcare through clinical integration, population health management and ACO development

FRISCO, Texas — Oct. 1, 2012 — Conifer Health Solutions, LLC, a subsidiary of Tenet Healthcare Corporation (NYSE:THC) and a leader in business process management solutions for healthcare providers, has entered into a definitive agreement to acquire InforMed Health Care Solutions located in Annapolis, Md.  InforMed is an information management and services company that uses cutting edge technology and powerful, proprietary data analysis tools to help healthcare providers, self-insured employers and payers lower costs, while improving care for their patients.

InforMed’s business includes 230 clients located in the Northeast, Mid-Atlantic and Midwest, more than 300 employees, extensive healthcare data and proprietary technology.  The acquisition will supplement Conifer Health’s existing suite of business process management solutions by providing additional population health management capabilities, expanding Conifer’s service offerings and accelerating their time to market.

“We are very excited to be adding such tremendous population health management resources to our existing Cap Management Systems group capabilities at Conifer Health,” said Stephen Mooney, president and chief executive officer of Conifer Health Solutions. “Conifer already manages 650,000 lives through clinical integration consulting, financial risk management and population health management services. This acquisition greatly expands our geographic footprint and accelerates our technological advancement of service offerings that we can take to market. We’ll be bringing in great talent from InforMed along with its exceptional tools and technology to supplement those services and enable us to find even better ways to lower healthcare costs. Once fully integrated, we expect InforMed to contribute more than $50 million in incremental annual revenues to Conifer.”

InforMed President and Chief Executive Officer Mitchell Davis stated he believes the two companies are a perfect fit because of their complementary strengths and areas of expertise. “Conifer’s Cap Management and InforMed are both committed to improving patient outcomes through the use of extensive data and proprietary technology. We’re both already making a difference in the quality of healthcare, and the synergy from combining these two companies will create a much stronger organization,” Davis said.

Davis added that for every dollar clients spend on InforMed medical management services, they typically reap between three and five dollars in savings. InforMed currently has over 2.5 million members in its data warehouse, more than one million members utilizing its medical management services and provides third-party administration services.
