Varian Medical Systems Acquires Sigma Micro Informatique Conseil

PALO ALTO, Calif., Jan. 17 /PRNewswire-FirstCall/ -- Varian Medical Systems, Inc., today announced that it has acquired Sigma Micro Informatique Conseil, a privately-held company that is the leading supplier of information management software for radiation oncology and medical oncology in cancer clinics and hospitals in France and other European nations. Varian paid approximately $13 million in cash to acquire the company, which is based in Toulouse, France.

"This is a logical extension of Varian's product line that enables us to offer customers a more comprehensive information management solution, particularly in international markets," said Christopher Hanna, Vice President for Varian Medical Systems' Oncology Information Systems business. "We are committed to providing all the tools needed for facilitating the delivery of effective cancer treatments."

"We believe the Sigma Micro will serve as an excellent compliment to our more fully-featured VARiS Vision(TM) software for information and image management within integrated Varian treatment networks," said Hanna. It also adds significant development resources to Varian's Oncology Information Systems' team, he said.

The acquisition enables Varian to provide French-speaking and other international clinics and hospitals with information management technology for managing and maintaining electronic health records for cancer patients receiving radiotherapy and/or chemotherapy. The Sigma Micro software supports billing in many different reimbursement schemes and works with equipment from multiple vendors, including Varian. It can be purchased, installed, commissioned and serviced over the web, making it a low-cost solution for clinics that are using other software for management of diagnostic and treatment planning images.

"We are very pleased to be joining Varian Medical Systems, which we recognize as the world's leading supplier of hardware and software for radiotherapy," said Sigma Micro's General Manager Pierre Fragnac, Ph.D., a physicist and one of the company's founders. "By being a part of Varian, we have the strongest possible platform for developing, marketing, servicing and supporting our technology."

Varian anticipates the acquisition will initially add annualized revenues of approximately $7 million and be neutral to earnings for the company in the current fiscal year. "We expect that our international sales, service, and support network will contribute to faster and deeper market penetration for this software product," Hanna said. The Sigma Micro software has more than 90 installed systems, mostly in France with the balance in Europe, Asia and North Africa.

Sigma Micro has 19 employees all of whom are expected to continue in their present roles, working with their existing customers from their facility in Toulouse.

Varian Medical Systems, Inc., of Palo Alto, California is the world's leading manufacturer of integrated cancer therapy systems, which are treating thousands of patients per day. The company is also a premier supplier of X- ray tubes and flat-panel digital subsystems for imaging in medical, scientific, and industrial applications.
