“2006 marked our 10^th anniversary and a year of considerable progress which culminated with record revenue results in the fourth quarter,” said Scott Kriens, Juniper Networks’ Chairman and CEO. “Moving into 2007, we see a marketplace that presents us with significant opportunity to deliver strategic value to customers, scale our ability to execute and continue to grow our business.”

Capital expenditures and depreciation during the fourth quarter of 2006 were $32.3 million and $20.7 million, respectively.

Highlights:
Juniper’s focus on innovation was reflected across a number of key product initiatives during the quarter.

For the service provider market, Juniper continued to invest and innovate delivering new features that improve operational efficiencies in next-generation core networks being deployed in response to increasing demand for multiplay service offerings.

New T-series enhancements included industry-leading point-to-multipoint JUNOS capabilities and new solutions to integrate optical transport and core IP routers. A new T-series 40 Gbps Interface Card delivers unprecedented interoperability and service agility over optical transport and IP network infrastructures. The latest features address service provider requirements in the strong installed base of more than 2,500 T-series routers deployed worldwide.

Also in the fourth quarter Juniper and NEC expanded its existing partnership and announced plans to jointly develop IMS-FMC solutions for the service provider market. Juniper and NEC are collaborating to deliver comprehensive, best-in-class solutions for both wired and wireless service providers.

On the enterprise side, Juniper announced its branch office strategy that includes standards-based application acceleration, IP telephony, routing and security designed to work with customers’ existing networks and accommodate future growth.

The branch office strategy also includes a range of new implementation services with Juniper WAN Application Acceleration technologies, as well as the integration of Intelligent Communications capabilities from Avaya into the J-series routers offering greater flexibility for customers.

Also announced in the fourth quarter was the integration completion of Juniper’s 802.1X components with the new Unified Access Control 2.0 solution, including elements of the Odyssey Access Client and Steel-Belted Radius. As an open standards-based Layer 2 and Layer 3 access control solution, UAC 2.0 can be deployed in a flexible array of deployment scenarios to give enterprises real-time visibility and granular policy control throughout the network.

Juniper continues leadership momentum with its position in the “Leaders” quadrant of Gartner’s Magic Quadrant for SSL VPN, North America, 3Q06 and Magic Quadrant for Network Intrusion Prevention System Appliances, 2H06. Juniper’s placement in the Leaders quadrant was based on the company’s completeness of vision and ability to execute in both the SSL VPN and IPS markets. Further, Infonetics Research, Inc. recognized Juniper as the second-largest security vendor in the industry and overall market share leader in the SSL VPN market. Juniper continued to maintain its Number 2 market share position in Service Provider and high-end enterprise routing for 16 and 4 consecutive quarters respectively according to Synergy Research Group.
