CAUTIONARY STATEMENTS

2

Forward-Looking Statements. This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of1934, as amended, which statements involve substantial risks and uncertainties. Except for historical information contained herein, all statements could be deemed forward-looking statement, including, without limitation, Juniper Networks’ views concerning our business outlook; economic and market outlook; our future financial and operating results; the expected impact of network transitions and timing of deployments with large customers; our capital return program; the potential impact of import tariffs; our expectations with respect to market trends; our future strategy; the strength of certain customer segments; our ability to expand business opportunities (including in hyperscale-switching, 5G buildouts and with enterprise customers); our expectations with respect to revenue growth or cost containment or our ability to improve profitability and make necessary investments; the introduction of future products; the strength of our solution portfolio; and overall future prospects.

Actual results or events could differ materially from those anticipated in those forward-looking statements as a result of several factors, including: general economic and political conditions globally or regionally; business and economic conditions in the networking industry; changes in overall technology spending by our customers; the network capacity requirements of our customers and, in particular, cloud and communication service providers; the timing of orders and their fulfillment; manufacturing and supply chain constraints, changes or disruptions; availability of product components; delays in scheduled product availability; adoption of regulations or standards affecting Juniper Networks’ products, services or the networking industry; the impact of import tariffs; and other factors listed in Juniper Networks’ most recent report on Form 10-Q and 10-K filed with the Securities and Exchange Commission. These forward-looking statements are not guarantees of future performance and speak only as of the date of this presentation. Juniper Networks undertakes no obligation to update the information in this presentation in the event facts or circumstances subsequently change.

Non-GAAP Financial Measures. This presentation contains information regarding Juniper Networks’ financial results prepared on a basis of accounting generally accepted in the United States of America (“GAAP”) as well as certain financial measures calculated and presented on the basis of methodologies other than in accordance with GAAP (“non-GAAP”). The non-GAAP financial measures disclosed by Juniper Networks should not be considered a substitute for, or superior to, the financial measures prepared in accordance with GAAP. Please refer to “Discussion of Non-GAAP Financial Measures” in our quarterly earnings release for a detailed explanation of the adjustments made to the comparable GAAP measures, the ways management uses the non-GAAP measures, and the reasons why management believes the non-GAAP measures provide investors with useful supplemental information.

With respect to future financial guidance provided on a non-GAAP basis, we exclude estimates for amortization of intangible assets, share-based compensation expenses, acquisition-related charges, restructuring benefits or charges, impairment charges, litigation settlement benefits or charges and resolution charges, supplier component remediation charges and recoveries, gain or loss on equity investments, retroactive impact of certain tax settlements, significant effects of tax legislation and judicial or administrative interpretation of tax regulations, including the impact of income tax reform, non-recurring income tax adjustments, valuation allowance on deferred tax assets, and the income tax effect of non-GAAP exclusions, and do not include the impact of any future acquisitions, divestitures, or joint ventures that may occur in the period. Juniper Networks is unable to provide a reconciliation of non-GAAP guidance measures to corresponding GAAP measures on a forward-looking basis without unreasonable effort due to the overall high variability and low visibility of most of the foregoing items that have been excluded. The items that are being excluded are difficult to predict and a reconciliation could result in disclosure that would be imprecise or potentially misleading. Material changes to any one of these items could have a significant effect on our guidance and future GAAP results.

Statement of Product Direction. Juniper Networks may disclose information related to development and plans for future products, features or enhancements (“SOPD”). SOPD information is subject to change at any time, without notice. Except as may be set forth in definitive agreements, Juniper Networks provides no assurances, and assumes no responsibility, that future products, features or enhancements will be introduced and third parties should not base purchasing decisions upon reliance of timeframes or specifics outlined in an SOPD, because Juniper may delay or never introduce the future products, features or enhancements.

Company Logos. Juniper Networks, the Juniper Networks logo, Juniper and Junos are registered trademarks of Juniper Networks, Inc. and/or its affiliates in the United States and other countries.
