“2007 was a strong year for Juniper Networks”, said Scott Kriens, Chairman and Chief Executive Officer of Juniper Networks, Inc. “Our people and products delivered a clear competitive advantage to our customers in the high-performance networking market, and our results speak for themselves. We look forward to 2008 as another high-performance year, where we believe the intensity of our focus and execution will produce accelerating growth and leverage across our business.”

Net cash flows from operations for the twelve months ended December 31, 2007 were $797.6 million, compared to cash provided by operations of $755.6 million for the 2006 fiscal year.

“Juniper’s key operating metrics were all in line or ahead of expectations in the December quarter,” said Robyn Denholm, Chief Financial Officer, Juniper Networks, Inc. “Strong revenue growth, good improvements in operating margin and record cash flow from operations were the highlights of the quarter. Our achievement of profitability in our SLT product group is also a key milestone for the company. We are on the right track and believe these results demonstrate our continuing commitment to financial and operational discipline.”

Q4 Highlights:

For the service provider market, Juniper announced the Partner Solution Development Platform (PSDP) that enables customers and partners to develop specialized applications on its best-in-class JUNOS software. The PSDP offers a powerful set of resources, including a software development kit (SDK) with intelligent and secure interfaces to JUNOS routing and service functions. These tools provide customers and partners with greater choice and control in designing, developing and deploying specialized applications that provide unique advantages to their businesses.

For the enterprise, Juniper continued to execute on its strategy to provide enterprises with advanced, coordinated visibility and control of applications and users across the extended enterprise with its announcement of Unified Access Control (UAC) 2.1. This solution advances the ability to deliver the access control, visibility and monitoring of applications and users needed to help address compliance requirements and mitigate exposure to risks and threats. Juniper also announced software enhancements for the WX and WXC application acceleration platforms that fortify application security without compromising performance.

2007 Highlights

Throughout the year, Juniper focused on advancing the fundamentals and economics of high-performance networking, delivering the fast, reliable secure network infrastructure high-performance businesses can rely on to accelerate the roll out of new applications and services to create value, differentiate themselves and accelerate growth.

For service providers, Juniper continued to execute on its vision for service-aware Next-Generation Networks (NGN). Juniper announced a new Session and Resource Control (SRC) solution that enables providers to allocate NGN resources in response to real-time requests from applications and users. Another key milestone for the company was the introduction of the T1600. Building on more than a decade of core routing experience, this next-generation core router extended the leadership of the T640, delivering unparalleled scalability and service richness. The T1600 also provides superior investment protection, enabling customers to upgrade currently installed T640 routers, in as little as 90 minutes, without service interruption. Juniper announced expansion of the MX-series of Ethernet Services Routers with the additions of the MX480 and MX240, offering providers’ performance at scale, superior quality of service (QoS) and enhanced service flexibility previously unattainable in Ethernet deployments. The PSDP provided the latest proof point of Juniper’s ability to extend the value of JUNOS and offer partners and customers new market-changing infrastructure solutions.

For the enterprise market, Juniper continued to focus on its proven, no compromise systems-based approach to delivering a high-performance network infrastructure with security at scale. Juniper was the first to provide advanced granular user and application visibility and control across the network within its integrated security and routing platforms (ISG and SSG). Juniper rolled out new branch networking offerings, expanding the J-series and SSG family to accelerate the secure delivery of business critical applications to branch offices. Juniper expanded its valued partnership with Microsoft to protect networks against downtime and loss by offering customers and partners open, standards-based interoperability between Juniper’s Unified Access Control (UAC) and Microsoft’s Network Access Protection (NAP). Together, the companies provide enterprises with greater choice, flexibility and investment protection for Network Access Control (NAC) deployments. The UAC 2.1 enhancements further streamline policy enforcement and mitigate risk to ensure information technology security initiatives deliver business value.

Fueling High-Performance Businesses

In the service provider market, the MX family continued to gain momentum, with customers such as Elion, a leading voice, Internet and data provider in Estonia, and Neo Telecoms, a leading French IP services operator, announcing their selection of the MX960 for their next-generation core and backbone networks, respectively. The T-series continued to be integral to many customers’ core upgrades. Verizon Business announced its intent to quadruple the standard speed of its backbone network connecting major US cities, using the T-series to deploy one of the first router-to-router 40Gbps (OC-768) circuits carrying live traffic. Chunghwa Telecom, Taiwan’s leading service provider, is building a unified IP core network to underpin its fixed-mobile convergence (FMC) strategy with Juniper’s T-series; Turk Telekom, Turkey’s incumbent telecoms operator, deployed Juniper’s T-series routers to upgrade network capacity and accelerate the introduction of new revenue-generating services; and Telefonica has upgraded its next-generation core IP network in Brazil by deploying Juniper’s T-series.

In the enterprise market, integrated routing and security solutions continued to gain traction. O’Neill, one of the world’s leading youth lifestyle and surfing brands is deploying Juniper’s Secure Services Gateway (SSG), along with NetScreen Security-Manager (NSM) to secure its growing network of retail branch offices across Europe. Japan’s University of Tsukuba, Dexia, a European banking group and a leader in financing services for the public sector, and Inner Mongolia Power all announced they will protect their network infrastructure with Juniper’s Integrated Security Gateway (ISG). Juniper also gained leverage from its service provider customers into the enterprise market in the form of managed services. A clear example of this was Verizon Business, who selected Juniper’s WXC platform as the technology to fuel their new Managed WAN Optimization Service.

Discussion of Non-GAAP Financial Measures

The table above includesthe following non-GAAP financial measuresfrom our Consolidated Statements of Operations: cost of product revenue; cost of service revenue; gross margin; gross margin as a percentage of revenue; research and development expense; sales and marketing expense; general and administrative expense; operating expense; operating income (loss); operating margin; net interest and other income; income before income taxes; provision for income taxes; income tax rate; net income (loss); net income (loss) per share and net income as a percentage of revenue. These measures are not presented in accordance with, nor are they a substitute for, U.S. generally accepted accounting principles, or GAAP. In addition, these measures may be different from non-GAAP measures used by other companies, limiting their usefulness for comparison purposes. The non-GAAP financial measures used in the table above should not be considered in isolation from measures of financial performance prepared in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.

We utilize a number of different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures presented above to be helpful in assessing the performance of the continuing operation of our business. By continuing operations we mean the ongoing revenue and expenses of the business excluding certain items that render comparisons with prior periods or analysis of on-going operating trends more difficult, such as expenses not directly related to the actual cash costs of development, sale, delivery or support of our products and services, or expenses that are reflected in periods unrelated to when the actual amounts were incurred or paid. Consistent with this approach, we believe that disclosing non-GAAP financial measures to the readers of our financial statements provides such readers with useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. In addition, we have historically reported non-GAAP results to the investment community and believe that continuing to provide non-GAAP measures provides investors with a tool for comparing results over time. In assessing the overall health of our business for the periods covered by the tables above and, in particular, in evaluating the financial line items presented in the table above, we have excluded items in the following three general categories, each of which are described below: Acquisition Related Expenses, Other Items, and Stock-Based Compensation Related Items. We also provide additional detail below regarding the shares used to calculate our non-GAAP net income per share. Notes identified for line items in the table above correspond to the appropriate note description below.

Note A: Acquisition Related Expenses. We exclude certain expense items resulting from acquisitions including the following: (i) amortization of purchased intangible assets associated with our acquisitions; (ii) compensation related to acquisitions; and (iii) acquisition related charges. The amortization of purchased intangible assets associated with our acquisitions results in our recording expenses in our GAAP financial statements that were already expensed by the acquired company before the acquisition and for which we have not expended cash. Moreover, had we internally developed the products acquired, the amortization of intangible assets and the expenses of uncompleted research and development would have been expensed in prior periods. Accordingly, we analyze the performance of our operations in each period without regard to such expenses. In addition acquisitions result in non-continuing operating expenses which would not otherwise have been incurred by us in the normal course of our business operations. For example, we have incurred deferred compensation charges related to assumed options and transition and integration costs such as retention bonuses and acquisition-related milestone payments to acquired employees. We believe that providing non-GAAP information for acquisition-related expense items in addition to the corresponding GAAP information allows the users of our financial statements to better review and understand the historic and current results of our continuing operations, and also facilitates comparisons to less acquisitive peer companies.

Note B: Other Items. We exclude certain other items that are the result of either unique or unplanned events including the following: (i) restructuring and related costs; (ii) impairment charges; (iii) stock option investigation costs and related tax costs; (iv) gain or loss on legal settlement, net of related transaction costs; (v) gain or loss on minority equity investment in privately held companies; and (vi) the income tax effect on our financial statements of excluding items related to our non-GAAP financial measures. It is difficult to estimate the amount or timing of these items in advance. Restructuring and impairment charges result from events which arise from unforeseen circumstances which often occur outside of the ordinary course of continuing operations. Although these events are reflected in our GAAP financials, these unique transactions may limit the comparability of our on-going operations with prior and future periods. The unique nature of our stock option investigation costs and associated tax related charges may also limit the comparability of our on-going operations with prior and future periods. Moreover, in the case of legal settlements, these gains or losses are recorded in the period in which the matter is concluded or resolved even though the subject matter of the underlying dispute may relate to multiple or different periods. As such, we believe that these expenses do not accurately reflect the underlying performance of our continuing operations for the period in which they are incurred. Whether we realize gains or losses on minority equity investments in privately held companies is based primarily on the performance and market value of those independent companies. Accordingly, we believe that these gains and losses do not reflect the underlying performance of our continuing operations. We also believe providing financial information with and without the income tax effect of excluding items related to our non-GAAP financial measures provides our management and users of the financial statements with better clarity regarding the on-going performance and future liquidity of our business. Because of these factors, we assess our operating performance both with these amounts included and excluded, and by providing this information, we believe the users of our financial statements are better able to understand the financial results of what we consider to be our continuing operations.

Note C: Stock-Based Compensation Related Items. We provide non-GAAP information relative to our expense for stock-based compensation and related payroll tax. We began to include stock-based compensation expense in our GAAP financial measures in accordance with Statement of Financial Accounting Standards No. 123 (revised 2004),Share-Based Payment, (“SFAS 123R”) in January 2006. Because of varying available valuation methodologies, subjective assumptions and the variety of award types which effect the calculations of stock-based compensation, we believe that the exclusion of stock-based compensation allows for more accurate comparisons of our operating results to our peer companies. Further, we believe that excluding stock-based compensation expense allows for a more accurate comparison of our financial results to previous periods during which our equity-based awards were not required to be reflected in our income statement. Stock-based compensation is very different from other forms of compensation. A cash salary or bonus has a fixed and unvarying cash cost. For example, the expense associated with a $10,000 bonus is equal to exactly $10,000 in cash regardless of when it is awarded and who it is awarded by. In contrast, the expense associated with an award of an option for 1,000 shares of stock is unrelated to the amount of compensation ultimately received by the employee; and the cost to the company is based on a stock-based compensation valuation methodology and underlying assumptions that may vary over time and that does not reflect any cash expenditure by the company because no cash is expended. Furthermore, the expense associated with granting an employee an option is spread over multiple years unlike other compensation expenses which are more proximate to the time of award or payment. For example, we may be recognizing expense in a year where the stock option is significantly underwater and is not going to be exercised or generate any compensation for the employee. The expense associated with an award of an option for 1,000 shares of stock by us in one quarter may have a very different expense than an award of an identical number of shares in a different quarter. Finally, the expense recognized by us for such an option may be very different than the expense to other companies for awarding a comparable option, which makes it difficult to assess our operating performance relative to our competitors. Similar to stock-based compensation, payroll tax on stock option exercises is dependent on our stock price and the timing and exercise by employees of our stock-based compensation, over which our management has little control, and as such does not correlate to the operation of our business. Because of these unique characteristics of stock-based compensation and the related payroll tax, management excludes these expenses when analyzing the organization’s business performance. We also believe that presentation of such non-GAAP information is important to enable readers of our financial statements to compare current period results with periods prior to the adoption of SFAS 123R.

Note D: Non-GAAP Net Income Per Share Items. We provide basic non-GAAP net income per share and diluted non-GAAP net income per share. The basic non-GAAP net income per share amount was calculated based on our non-GAAP net income and the weighted-average number of shares outstanding during the reporting period. The diluted non-GAAP income per share included additional dilution from potential issuance of common stock, except when such issuances would be anti-dilutive.
