Dassault Systèmes Tops CIMdata CAM Survey;
Overtakes Competition

2006 Revenue Figures Validate DS has World’s Largest
Share in the Computer-Aided Manufacturing Software Market

Paris, France, June 12 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced that it has been named the global market share leader in computer-aided manufacturing (CAM) software revenue by the international technology research firm CIMdata.

Dassault Systèmes is the top company in vendor revenues received and end user payments, according to CIMdata’s 2006 NC Software and Related Services Market Assessment Report. The report evaluated between 20 and 30 vendors in various CAM market leadership categories. Dassault Systèmes’ closest competitors in the PLM industry lost market share. Dassault Systèmes also ranked among the five largest brands in terms of industrial seats shipped.

“The CAM market remains fragmented, despite recent acquisitions. Dassault Systèmes’ revenue leadership illustrates the value customers perceive in integrated CAD/CAM and digital manufacturing capabilities,” said Alan Christman, CIMdata chairman and primary author of the report.

CAM is an important part of PLM implementations. It spans computer-aided design (CAD) and digital manufacturing, enabling companies to design production operations faster and more accurately than through conventional processes.

“This ranking validates the value we bring to our customers through our investments in new product and technology R&D, and also in our sales and support channels,” said Jacques Leveillé-Nizerolle, CATIA brand CEO, Dassault Systèmes. “CAM is a major link in the PLM chain, and we have worked hard to provide our customers with CAM products that help them realize the maximum return on their PLM investments.”

Companies in a wide range of industries, including aerospace, automotive, medical equipment, shipbuilding and consumer goods, use DS’s CATIA® design authoring solution for a variety of computer-aided manufacturing tasks, from toolpath generation and verification for simple lathe machining, 2.5 axis machining and very complex five axis machining, all the way to post-processing functions. CATIA’s native link to DS’s DELMIA® digital manufacturing solutions allow efficient manufacturing modeling, machining process planning and CMM support in a virtual 3D environment.
