Item 2.02 Results of Operations and Financial Condition.
On April 24, 2008, Juniper Networks, Inc. ("we", "us" or "the Company") issued a press release in which we announced financial results for the quarter ended March 31, 2008. A copy of the press release is furnished as Exhibit 99.1 to this report. Exhibit 99.1 shall not be treated as filed for purposes of the Securities Exchange Act of 1934, as amended.

Discussion of Non-GAAP Financial Measures

The tables contained in the press release furnished as Exhibit 99.1 to this report include a table presenting the following non-GAAP financial measures from our Condensed Consolidated Statements of Operations: cost of product revenue; cost of service revenue; product gross margin; product gross margin as a percentage of revenue; service gross margin; service gross margin as a percentage of 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; operating margin; net interest and other income; income before income taxes; provision for income taxes; income tax rate; net income; net income 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 described herein, and identified in the table in our press release, 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 in our press release 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 non-cash 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 in our press release and, in particular, in evaluating the non-GAAP financial line items presented in the table in our press release, 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 in our press release 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.

JUNIPER NETWORKS REPORTS FIRST QUARTER 2008 FINANCIAL RESULTS

 	•	 	Revenue: $822.9M, up 31% from Q1’07;	

 	•	 	Net Income: $110.4 million (GAAP); $149.5 million (non-GAAP)	

 	•	 	EPS: $0.20 (diluted, GAAP); $0.27 (diluted, non-GAAP), up 44% from Q1’07 on improved operating performance	
SUNNYVALE, Calif., April 24, 2008 – Juniper Networks, Inc. (NASDAQ: JNPR) today reported financial results for the three months ended March 31, 2008 that included strong revenue and profit growth and improved operating profit margins.
Net revenues for the first quarter of 2008 rose 31 percent on a year-over-year basis to $822.9 million. The Company posted GAAP net income of $110.4 million or $0.20 per diluted share, and non-GAAP net income of $149.5 million or $0.27 per diluted share. The non-GAAP EPS figure represents an increase of 44% from the $0.19 per diluted share reported for the first quarter of 2007. The reconciliation between GAAP and non-GAAP results of operations is provided in a table immediately following the Net Revenues by Reportable Segment table below.
“The strength of our first quarter results continue to underscore the value of Juniper’s commitment to high-performance networking,” said Scott Kriens, chairman and chief executive officer, Juniper Networks, Inc. “Across our markets and around the world, we are seeing clear opportunity to extend our lead through an optimal combination of Juniper size, speed, focus and execution, which translates directly into strategic advantage for our customers.”
Juniper’s operating margin rose to 17.3% on a GAAP basis from 9.6% in the same quarter a year-ago. Non-GAAP operating margin rose to 23.5% from 19.6% in the first quarter of 2007. The improvement reflected strength in gross profit margins owing to a favorable mix of infrastructure products, particularly in the Company’s T and M series products, as well as reduced operating expense as a percentage of net revenues due to the Company’s efforts to manage expenses and improve efficiency.
The improved operating margins helped Juniper generate net cash from operations for the first quarter of 2008 of $254.9 million, compared to cash provided by operations of $151.5 million for the same quarter of 2007.
Capital expenditures as well as depreciation and amortization expense during the first quarter of 2008 were $33.4 million and $55.4 million, respectively.
“I’m pleased with this strong start to 2008,” stated Robyn Denholm, chief financial officer, Juniper Networks, Inc. “Our March quarter results reflect our focus on building operating leverage into our business model. Our operational excellence programs (4 P’s) to optimize our business are well underway and we will continue implementing our plans in the coming quarters.”
Q1 Highlights
High-Performance Network Infrastructure
Juniper reaffirmed its commitment to delivering innovative, high-performance network infrastructure solutions to the enterprise market with the introduction and first shipments of the EX-series, a family of Ethernet switches. Leveraging the operational simplicity and carrier-class reliability of JUNOS software, the EX-series alleviates the cost, complexity and risk associated with managing legacy switch infrastructures, and accelerates the deployment of business-enabling applications and services across the network. Juniper also announced the integration of services, including firewall, VPN and chassis clustering into JUNOS software for implementation on the J-series services router to enhance the security and reduce the complexity of small office and branch networks. Following the end of Q1’08, Juniper extended its security offerings with the introduction of a series of next-generation SSL VPN appliances designed to ensure fast, reliable and secure remote access to applications and services for the most complex and demanding secure environments; new Intrusion Detection and Prevention (IDP) appliances that scale up to 10 Gbps, which represents the industry’s highest real-world throughput, performance and density combination; and in the first quarter Juniper also introduced the Security Threat Response Manager (STRM), capable of providing businesses with a centralized scalable and effective way to log and manage a rapidly evolving threat landscape, while sustaining adherence to compliance mandates.
For the service provider market, Juniper introduced an advanced mobile IP/MPLS solution portfolio with the new BX 7000 multi-access gateway router for the cell site, a new M-series circuit emulation and physical interface cards for the aggregation site and a suite of software features designed to simplify deployment, provisioning and management of mobile backhaul networks. This advanced solution will enable mobile operators to preserve their current investments and services, while accelerating the roll-out of new user-centric services. Juniper also introduced the JCS 1200, the industry’s first high-performance control plane scaling platform. The independent scale of control and forwarding plane resources will help carriers to maximize service growth, operational efficiencies and control. When deployed in conjunction with the T1600 router, the JCS 1200 can create hardware-virtualized routers, delivering as much as three times the forwarding capacity of competitive systems, while using 25 percent less rack space. This unique architecture enables service providers to rapidly expand their service offerings and helps to reduce capital and operating expenditures.
Fueling High-Performance Businesses
In the service provider market, Juniper completed its first full quarter of shipping the T1600 multi-terabit core router, and exiting the quarter had booked orders for more than 105 units and shipped more than 77 units to customers for deployment in production networks around the world. T-series customer deployments in the quarter included Tiscali International Network, the wholesale carrier division of the Tiscali Group, and HiNet, a wholly owned subsidiary of Chunghwa Telecom in Taiwan. Global adoption of the MX-series, Juniper’s carrier Ethernet services router family, continued through the quarter with deployment announcements from PeterStar, a leading Russian telecommunications provider, SpectrumNet, a leading Bulgarian telecommunications provider, nLayer, a leading North American provider of Internet connectivity and wholesale bandwidth and Carphone Warehouse, one of the largest independent service providers in the U.K.
In the enterprise market, Juniper continues to build momentum and deliver the networking solutions high-performance businesses need to reduce operational complexity and costs, accelerate the roll-out of business critical applications and services, and differentiate themselves in the market. Secure access to applications continues to be a focus, with customers, including Bankdata, a leading financial services provider in Denmark, which is deploying Juniper SSL VPN solutions to grant secure access to network resources. In the public sector, Juniper participated in the National “Cyber Storm II” exercise sponsored by the U.S. Department of Homeland Security, which aimed to examine the processes, procedures, tools and organizational responses required to successfully defend against a multi-sector coordinated attack on the global cyber infrastructure, or respond to a natural disaster.

Discussion of Non-GAAP Financial Measures
The table above includes the following non-GAAP financial measures from our Condensed Consolidated Statements of Operations: cost of product revenue; cost of service revenue; product gross margin, product gross margin as a percentage of revenue; service gross margin; service gross margin as a percentage of 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; operating margin; net interest and other income; income before income taxes; provision for income taxes; income tax rate; net income; net income 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.
