Paris, France, April 11, 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM)
solutions, today announced it ranked first in direct and mindshare PLM revenues in the 2006 CIMdata survey of comprehensive PLM companies. Ann Arbor, Michigan-headquartered CIMdata is one of the world’s leading PLM consultancies.

“Dassault Systèmes is the 2006 overall PLM revenue leader among the top tier of comprehensive PLM companies – the players that customers typically acknowledge are driving the market,” said Ed Miller, president of CIMdata. “The company has made many strategic moves over the last few years to expand their PLM offerings as customer needs have evolved. As our analysis shows, the market has noticed by rewarding Dassault Systèmes with very high recognition, growing revenues, and a strong market share.”

CIMdata’s PLM Market Analysis calculated Dassault Systèmes “market footprint” at $2.9 billion, or over $800 million more than the nearest competitor. The report defines market footprint as the company’s direct and partner-generated PLM revenues. The PLM Market Analysis also ranked Dassault Systèmes as the leader in direct revenues at $1.5 billion, or almost $300 million more than the nearest competitor. The report also ranked DS first in revenue of the PLM Mindshare leaders. Mindshare leaders are the companies with the largest and most innovative PLM implementations, and those perceived by customers as thought and technology leaders. In addition to Dassault Systèmes’ revenue and mindshare leadership, CIMdata’s analysis indicates Dassault Systèmes grew its collaborative product definition management revenues by 59 percent, the fastest among its main competitors fueled by both internal growth and its acquisition of MatrixOne.

“Perhaps the most gratifying part of this report is seeing that Dassault Systèmes is the company most often associated with the term PLM,” said Philippe Forestier, Dassault Systèmes’ executive vice president, Network Selling, and the company’s leading executive in the Americas. “Not only is our share of the collaborative product definition management sub segment growing faster than any of our competitors, but CIMdata also documented a 10.4 percent increase in overall PLM spending in 2006. We are happy to know that the market Dassault Systèmes leads has such momentum.” The PLM revenue figures include the main functional areas of PLM, from design authoring to enterprise collaboration to digital manufacturing, plus complementary applications from companies and their partner networks. To rank among PLM mindshare leaders, companies must have a comprehensive product and service offering that covers the entire product development cycle and supporting business processes.
