MontaVista Software Acquisition by Cavium Networks

Mountain View, CA – Cavium Networks (NASDAQ: CAVM), a leading provider of highly integrated semiconductor products that enable intelligent processing for networking, wireless, storage and video applications, today announced that they have completed their acquisition of MontaVista Software, Inc., finalizing an agreement that was announced on November 10, 2009.

MontaVista Software is a leader in multi-core embedded Linux operating systems, virtualization, development tools and professional services with a broad array of Tier-1 customers. Embedded Linux is fast becoming the operating system of choice for hundreds of millions of devices ranging from very large carrier grade equipment to consumer electronics. Traditionally embedded devices used a proprietary OS or commercial real-time operating system. However, there is a major trend towards using embedded Linux. This rapid adoption of Linux in embedded networking, wireless, consumer electronics, mobile devices and storage is driving the demand for a high quality, commercial grade embedded Linux along with support for multi-core processors and embedded virtualization.

Software is becoming an increasingly important part of the total multi-core processor solution and this acquisition will complement Cavium Network’s broad portfolio of multi-core processors to deliver more highly compelling, integrated and differentiated embedded solutions to the market.

The MontaVista brand name will continue to be used and MontaVista will maintain its own dedicated and focused engineering, sales and product management staff along with supporting multiple processor architectures from leading semiconductor vendors. MontaVista’s customers and partners will see no change in customer facing field operations and the web-based support and product download sites will be maintained. Art Landro, previously Executive Vice President of MontaVista’s Worldwide Field Operations, has been appointed as the President of MontaVista Software. Prior to joining MontaVista in 2007, Art Landro held Vice President positions at EMC Corporation, Documentum, Cadence Design, and General DataComm.
