Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The Condensed Consolidated Financial Statements of Juniper Networks, Inc. (the “Company” or “Juniper”) were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2019 has been derived from the audited Consolidated Financial Statements at that date. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any future period.

These Condensed Consolidated Financial Statements and accompanying notes should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 (the "Form 10-K"). We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued.

The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Actual results could differ materially from those estimates under different assumptions or conditions.

Summary of Significant Accounting Policies

Except for the change in certain policies upon adoption of the accounting standards and the policy for interest rate lock cash flow hedges described below, there have been no significant changes to the Company's significant accounting policies described in Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

The Company records changes in fair value of interest rate locks in accumulated other comprehensive income (loss) in the consolidated balance sheets, in the period of change. When the forecasted transaction occurs, the Company will start to amortize the accumulated gain or losses included as a component of other comprehensive income (loss) related to the interest rate lock cash flow hedges to interest expense. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) will be reclassified to other income and expense within income statement.

Recently Adopted Accounting Standards

Fair Value Measurement: On January 1, 2020, the Company adopted ASU No. 2018-13 (Topic 820) Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds, and modifies certain disclosure requirements for fair value measurements under ASC 820. The Company adopted the standard under the prospective approach for certain modified or new disclosure requirements, and all other amendments in the standard under the retrospective approach. See Note 3, Fair Value Measurements for required disclosures.

Simplifying the Test for Goodwill Impairment: On January 1, 2020, the Company adopted ASU No. 2017-04 (Topic 350) Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. The Company adopted the standard under the prospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Credit Losses on Financial Instruments: On January 1, 2020, the Company adopted ASU 2016-13 (Topic 326) Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments, as further clarified by the Financial Accounting Standards Board (the "FASB") through the issuance of additional related ASUs, which requires the measurement and recognition of current expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model, which requires the use of forward-looking information to calculate credit loss

estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. The Company adopted the standard under the modified retrospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Recent Accounting Standards Not Yet Adopted

Reference Rate Reform: In March 2020, the FASB issued ASU No. 2020-04 (Topic 848), Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients and exceptions to the existing guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (SOFR). The standard was effective upon issuance and may generally be applied through December 31, 2022, to any new or amended contracts, hedging relationships, and other transactions that reference LIBOR. The Company is currently evaluating the impact of the transition and disclosure requirements of the standard on its Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes: In December 2019, the FASB issued ASU No. 2019-12 (Topic 740) Income Taxes — Simplifying the Accounting for Income Taxes, which enhances and simplifies various aspects related to accounting for income taxes. This ASU is to be applied on a prospective basis with the exception of certain amendments that are to be applied on either a retrospective or modified retrospective basis. The new standard is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.

For available-for-sale debt securities that have unrealized losses, the Company assesses impairment by evaluating various factors, including whether (i) it has the intention to sell any of these investments and (ii) whether it is more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company periodically assesses performance indicators of the investment by evaluating various factors such as (i) changes in the credit ratings and (ii) review of the issuer. As of June 30, 2020, the Company had 121 investments in unrealized loss positions. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. The Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no allowance for credit losses was required to be recognized during the three and six months ended June 30, 2020 and June 30, 2019.

During the three and six months ended June 30, 2020 and June 30, 2019, there were no material gross realized gains or losses from available-for-sale debt securities.

The Company's Level 2 available-for-sale debt securities are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's derivative instruments are classified as Level 2, as they are not actively traded and are valued using pricing models that use observable market inputs. During the three and six months ended June 30, 2020, the Company had no transfers into or out of Level 3 of the fair value hierarchy of its assets or liabilities measured at fair value.

The Company's privately-held debt and redeemable preferred stock securities are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value of its privately-held debt and redeemable preferred stock securities on a recurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent valuations at the time of financing activities and the investee's capital structure. During the three and six months ended June 30, 2020, there were no significant activities related to privately-held debt and redeemable preferred stock securities.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

The Company's investments in equity securities without readily determinable fair value are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value on a nonrecurring basis (i.e. when an observable transaction occurs) using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. As of June 30, 2020, there have been no material upward or downward adjustments for price changes to the equity securities without readily determinable fair value.

Certain of the Company's assets, including intangible assets and goodwill, are measured at fair value on a nonrecurring basis. There were no significant impairment charges recognized during the three and six months ended June 30, 2020.

As of June 30, 2020 and December 31, 2019, the Company had no liabilities required to be measured at fair value on a nonrecurring basis.

Assets and Liabilities Not Measured at Fair Value

The carrying amounts of the Company's accounts receivable, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. As of June 30, 2020 and December 31, 2019, the estimated fair value of the Company's total outstanding debt in the Condensed Consolidated Balance Sheets was $1,950.1 million and $1,852.1 million, respectively, based on observable market inputs (Level 2). The carrying value of the promissory note issued to the Company in connection with the previously completed sale of Junos Pulse, along with the accumulated interest paid in kind, of $87.4 million and $78.9 million approximates its fair value as of June 30, 2020 and December 31, 2019, respectively. Notes receivable are generally classified as Level 3 assets due to the lack of observable inputs to determine fair value. The carrying value of a contract manufacturer deposit of $62.3 million, reported within other long-term assets, in the Condensed Consolidated Balance Sheets approximates its fair value as of June 30, 2020. See Note 5, Other Financial Information, for further information on the contract manufacturer deposit.

Designated Derivatives

The Company uses foreign currency forward contracts to hedge the Company's planned cost of revenues and operating expenses denominated in foreign currencies. These derivatives are designated as cash flow hedges and typically have maturities of thirty-six months or less.

During the three months ended June 30, 2020, the Company entered into interest rate locks with large financial institutions, which fixed benchmark interest rates of future debt issuance for an aggregate notional amount of $550.0 million. The swaps are designated as cash flow hedges and are expected to terminate within 5 years and 3 months.

In 2019, the Company entered into interest rate swaps with an aggregate notional amount of $300.0 million designated as fair value hedges of our fixed-rate 2041 Notes. These swaps convert the fixed interest rates of the notes to floating interest rates based on the LIBOR. Most of the interest rate swaps will expire within ten years or less.

Effect of Derivative Instruments on the Consolidated Statements of Operations

For cash flow hedges, the Company recognized an unrealized gain of $17.9 million and an unrealized loss of $11.2 million in accumulated other comprehensive income for the effective portion of its derivative instruments for the three and six months ended June 30, 2020, respectively. The Company recognized an unrealized loss of $2.1 million and an unrealized gain of $1.3 million in accumulated other comprehensive income for the effective portion of its derivative instruments for the three and six months ended June 30, 2019, respectively.

For foreign currency forward contracts, the company reclassified a loss of $6.9 million and $8.3 million out of accumulated other comprehensive income to cost of revenues and operating expenses in the Condensed Consolidated Statements of Operations during the three and six months ended June 30, 2020, respectively, and a gain of $0.3 million and loss of $0.7 million for the comparable periods ended June 30, 2019, respectively. As of June 30, 2020, an estimated $7.9 million of unrealized net loss within accumulated other comprehensive loss is expected to be reclassified into earnings within the next twelve months.

Non-Designated Derivatives

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. These foreign exchange forward contracts typically have maturities of approximately one to four months. The outstanding non-designated derivative instruments are carried at fair value. Changes in the fair value of these derivatives, which were recorded in other expense, net within the Condensed Consolidated Statements of Operations, were not material during the three and six months ended June 30, 2020 and June 30, 2019.

Note 6. Restructuring Charges

During the first quarter of 2020, the Company initiated a restructuring plan (the "2020 Restructuring Plan") designed to realign its workforce with the Company's sales strategy, enhance productivity and cost efficiencies, and enable reinvestment in certain key priority areas. During the second quarter of 2020, the Company amended the 2020 Restructuring Plan and undertook further actions that resulted in additional severance costs.

During the three months ended June 30, 2020, the Company recorded $4.8 million in severance costs related to workforce reductions. During the six months ended June 30, 2020, the Company recorded $8.9 million in severance and $5.3 million in impairment charges included in other exit related costs, which were reported as restructuring charges in the Condensed Consolidated Statements of Operations.

Restructuring liabilities are reported within other accrued liabilities in the Condensed Consolidated Balance Sheets. The following table provides a summary of changes in the restructuring liabilities for the Company's 2020 and prior year restructuring plan (in millions):

	December 31, 2019		Charges		Cash Payments			Other			June 30, 2020

________________________________

^(*)  During the six months ended June 30, 2020, the $23.83 average price per share includes $200.0 million in open market purchases, and settlement of the forward contract of $40.0 million under the ASR, which was initiated during the fourth quarter of 2019. During the three and six months ended June 30, 2019, the $27.94 average price per share excludes the forward contract of $60.0 million under the ASR, which was initiated and settled during the second and the third quarter of 2019, respectively.

Cash Dividends on Shares of Common Stock

During the three and six months ended June 30, 2020, the Company declared a quarterly cash dividend of $0.20 per share of common stock on January 27, 2020 and April 28, 2020, respectively, which was paid on March 23, 2020 and June 22, 2020, respectively, to stockholders of record on March 2, 2020 and June 1, 2020. Any future dividends, and the establishment of record and payment dates, are subject to approval by the Board of Directors (the “Board”) of Juniper or an authorized committee thereof. See Note 14, Subsequent Events, for discussion of the Company's dividend declaration subsequent to June 30, 2020.

Stock Repurchase Activities

In January 2018, the Board approved a $2.0 billion share repurchase program ("2018 Stock Repurchase Program"), which replaced our prior authorization. In October 2019, the Board authorized a $1.0 billion increase to the 2018 Stock Repurchase Program for a total of $3.0 billion.

In October 2019, the Company entered into an ASR, to repurchase an aggregate of approximately $200.0 million of the Company’s outstanding common stock. During the three months ended December 31, 2019, the Company made an up-front payment of $200.0 million pursuant to the ASR and received and retired an initial 6.4 million shares of the Company’s common stock for an aggregate price of $160.0 million, based on the market price of $25.15 per share of the Company’s common stock on the date of the transaction. During the three months ended March 31, 2020, the ASR was completed, and an additional 1.8 million shares were received for a total repurchase of 8.2 million shares of the Company's common stock at a volume weighted average repurchase price, less an agreed upon discount, of $24.44 per share. The shares received by the Company were retired, accounted for as a reduction to stockholder’s equity in the Condensed Consolidated Balance Sheets, and treated as a repurchase of common stock for purposes of calculating earnings per share.

During the six months ended June 30, 2020, the Company also repurchased 8.5 million shares of its common stock in the open market for an aggregate purchase price of $200.0 million at an average price of $23.70 per share, under the 2018 Stock Repurchase Program.

As of June 30, 2020, there was approximately $1.5 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

Future share repurchases under the 2018 Stock Repurchase Program will be subject to a review of the circumstances at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. The Company's 2018 Stock Repurchase Program may be discontinued at any time.

In addition to repurchases under the 2018 Stock Repurchase Program, the Company also withholds shares of common stock from certain employees in connection with the vesting of stock awards issued to such employees to satisfy applicable tax withholding requirements. Such withheld shares are treated as common stock repurchases in our financial statements as they reduce the number of shares that would have been issued upon vesting. Repurchases associated with tax withholdings were not material during the three and six months ended June 30, 2020 and June 30, 2019.

Accumulated Other Comprehensive Loss, Net of Tax

The components of accumulated other comprehensive loss, net of related taxes, for the six months ended June 30, 2020 were as follows (in millions):

Note 9. Employee Benefit Plans

Equity Incentive Plans

The Company has stock-based compensation plans pursuant to which it has granted stock options, restricted stock units (“RSUs”), and performance share awards (“PSAs”). The Company also maintains its 2008 Employee Stock Purchase Plan (the “ESPP”) for all eligible employees. As of June 30, 2020, 15.9 million and 12.9 million shares were available for future issuance under the Company's 2015 Equity Incentive Plan (the "2015 Plan") and the ESPP, respectively. In connection with past acquisitions, the Company has also assumed or substituted stock options, RSUs, restricted stock awards ("RSAs"), and PSAs.

RSU, RSA and PSA Activities

The Company’s RSU, RSA and PSA activity and related information as of and for the six months ended June 30, 2020 were as follows (in millions, except per share amounts and years):

	Outstanding RSUs, RSAs and PSAs
	Number of Shares		Weighted Average Grant-Date Fair Value per Share		Weighted Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value
Balance as of December 31, 2019	17.5		$	25.30
Granted(*)	3.2		22.57
Vested	(5.1	)	25.98
Canceled	(1.5	)	25.44
Balance as of June 30, 2020	14.1		$	24.42	1.3	$	321.5

________________________________

^(*)  Includes 2.0 million service-based, 0.8 million performance-based, and 0.4 million market-based RSUs. The number of shares subject to performance-based and market-based conditions represents the aggregate maximum number of shares that may be issued pursuant to the award over its full term. The grant date fair value of RSUs and PSAs was reduced by the present value of dividends expected to be paid on the underlying shares of common stock during the requisite and derived service period as these awards are not entitled to receive dividends until vested.

Employee Stock Purchase Plan

The following table summarizes employee stock purchases through the ESPP (in millions, except per share amounts):

	Six Months Ended June 30,
	2020		2019
Shares purchased	1.4		1.2
Average exercise price per share	$	19.50	$	22.04

The ESPP provides a 24-month offering period with four 6-month purchase periods. A new 24-month offering period commences every six months. The purchase price for the Company’s common stock under the ESPP is 85% of the lower of the fair market value of the shares at (1) the beginning of the applicable offering period or (2) the end of each 6-month purchase period during such offering period. The ESPP will continue in effect until February 25, 2028, unless terminated earlier under the provisions of the ESPP.

Note 11. Income Taxes

The following table provides details of income taxes (in millions, except percentages):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Income before income taxes	$	86.1		$	77.8		$	114.4		$	122.3
Income tax provision	$	24.9		$	31.6		$	32.8		$	45.0
Effective tax rate	28.9		%	40.6		%	28.7		%	36.8		%

The Company’s effective tax rate differs from the federal statutory rate of 21% primarily due to the tax impact of state taxes, geographic mix of earnings including foreign-derived intangible income deductions and global intangible low-taxed income, research and development ("R&D") tax credits, tax audit settlements, nondeductible compensation, cost sharing of stock-based compensation, and other transfer pricing adjustments.

On June 7, 2019, the Ninth Circuit Court of Appeals issued an opinion in Altera Corp. v. Commissioner requiring related parties in an intercompany cost-sharing arrangement to share expenses related to stock-based compensation. On February 10, 2020, Altera appealed this decision to the U.S. Supreme Court, which on June 22, 2020, declined to review the decision. Based on the Supreme Court decision to not review the Ninth Circuit Court’s decision, stock-based compensation is subject to cost sharing, and the Company recorded a $18.2 million charge.

The Company’s effective tax rate during the six months ended June 30, 2020 reflects the cumulative impact of cost sharing for stock-based compensation of $18.2 million referenced above, partially offset by a reduction of income tax reserves of $15.2 million, which includes interest of $1.7 million.

The Company's effective tax rate during the six months ended June 30, 2019 reflected the impact of an international realignment and a related write-down of certain deferred tax assets.

As of June 30, 2020, the total amount of gross unrecognized tax benefits was $152.7 million.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by a range of approximately $23.0 million to $44.0 million within the next twelve months due to the completion of tax review cycles in various tax jurisdictions and lapses of applicable statutes of limitations.

Note 13. Commitments and Contingencies

Commitments

Except for the items below, there have been no material changes to the Company's commitments compared to the commitments described in Note 16, Commitments and Contingencies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

Unconditional Purchase Obligations

Unconditional purchase obligations consist of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices. During the second quarter of 2020, the Company amended its existing Master Services Agreement and certain Statements of Work (collectively, the "Agreement") with International Business Machines Corporation ("IBM"), resulting in a $79.4 million reduction in fees payable to IBM over the remaining initial term of the Agreement.

Purchase Commitments with Contract Manufacturers and Suppliers

In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $1,524.3 million as of June 30, 2020.

The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Company’s demand forecast or customer orders. As of June 30, 2020, the Company had accrued $21.3 million based on its estimate of such charges.

Legal Proceedings

In the ordinary course of business, the Company is subject to various pending and potential investigations, disputes, litigations, and legal proceedings. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company intends to aggressively defend itself in any legal matters, and while the outcome of any pending matters is not currently determinable, the Company believes that none of its currently existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or any other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of these events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q, which we refer to as the Report, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements regarding future events and the future results of Juniper Networks, Inc., which we refer to as “we,” “us,” "Juniper," or the “Company,” that are based on our current expectations, estimates, forecasts, and projections about our business, economic and market outlook, our results of operations, the industry in which we operate and the beliefs and assumptions of our management. Words such as “expects,” “anticipates,” “targets,” “goals,” “projects,” “would,” “will,” “could,” “may,” “intends,” “plans,” “believes,” “seeks,” “estimates,” variations of such words, and similar expressions are intended to identify such forward-looking statements. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, and these forward-looking statements are only predictions and are subject to risks, uncertainties, and assumptions that are difficult to predict, including the duration, extent, and impact of the COVID-19 pandemic, and our ability to successfully manage the demand, supply, and operational challenges associated with the COVID-19 pandemic. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in this Report under the section entitled “Risk Factors” in Item 1A of Part II and elsewhere, and in other reports we file with the U.S. Securities and Exchange Commission, or the SEC. In addition, many of the foregoing risks and uncertainties are, and could be, exacerbated by the COVID-19 pandemic and any worsening of the global business and economic environment as a result. While forward-looking statements are based on reasonable expectations of our management at the time that they are made, you should not rely on them. We undertake no obligation to revise or update publicly any forward-looking statements for any reason, except as required by applicable law. We cannot at this time predict the extent of the impact of the COVID-19 pandemic and any resulting business or economic impact, but it could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The following discussion is based upon our unaudited Condensed Consolidated Financial Statements included in Part 1, Item I, of this Report, which were prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. In the course of operating our business, we routinely make decisions as to the timing of the payment of invoices, the collection of receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase of supplies, and the building of inventory and spare parts, among other matters. In making these decisions, we consider various factors, including contractual obligations, customer satisfaction, competition, internal and external financial targets and expectations, and financial planning objectives. Each of these decisions has some impact on the financial results for any given period.

To aid in understanding our operating results for the periods covered by this Report, we have provided an executive overview, which includes a summary of our business and market environment along with a financial results and key performance metrics overview. These sections should be read in conjunction with the more detailed discussion and analysis of our condensed consolidated financial condition and results of operations in this Item 2, our “Risk Factors” section included in Item 1A of Part II of this Report, and our unaudited Condensed Consolidated Financial Statements and Notes included in Item 1 of Part I of this Report, as well as our audited Consolidated Financial Statements and Notes included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, or Form 10-K.

Business and Market Environment

Juniper Networks designs, develops and sells products and services for high-performance networks to enable customers to build scalable, reliable, secure and cost-effective networks for their businesses, while achieving agility and improved operating efficiency through automation. We sell our products in more than 150 countries in three geographic regions: Americas; Europe, Middle East, and Africa, which we refer to as EMEA; and Asia Pacific, which we refer to as APAC. We organize and manage our business by major functional departments on a consolidated basis as one operating segment. We sell our high-performance network products and service offerings across routing, switching, and security technologies. In addition to our products, we offer our customers services, including maintenance and support, professional services, and education and training programs.

Our products and services address high-performance network requirements for our customers within our verticals: Cloud, Service Provider, and Enterprise who view the network as critical to their success. We believe our silicon, systems, and software represent innovations that transform the economics and experience of networking, helping our customers achieve superior performance, greater choice, and flexibility, while reducing overall total cost of ownership.

Further, we intend to expand our software business by introducing new software solutions to our product portfolio that simplify the operation of networks and allow our customers across our key verticals flexibility in consumption and deployment. Our acquisition of Mist Systems, or Mist, in 2019 accelerated our ability to execute on this belief in cloud-managed, artificial intelligence, or AI-enabled enterprise networking operations through a combination of cloud-based intelligence, enterprise-grade access points,

33

and EX series switches. Machine learning technology simplifies wireless and wired operations, and delivers a more agile cloud services platform.

During the first half of 2020, we continued to execute on our product and solutions strategy and announced Mist Premium Analytics, a service that offers enterprises a comprehensive network visibility and business insights platform to support the increasing demands of digital transformation projects. We also expanded on our connected security portfolio by offering encrypted traffic analysis for Juniper Advanced Threat Prevention Cloud and SRX Series firewalls, as well as the integration of security intelligence, or SecIntel, to the Mist platform for wireless access. With these additions to our connected security solution portfolio, we deliver a comprehensive offering to secure traffic within an organization, whether encrypted or unencrypted, throughout parts of the network, whether access, campus, WAN or data center. During the first quarter of 2020, we also released our 36 port, 400 Gigabit Ethernet line card that provides 14.4-Tbps, which is based on the scalable custom Juniper Triton silicon, that helps provide programmability, scalability, automation, and pervasive security in a single, cost-optimized router. During the second quarter of 2020, although COVID-19 pandemic related supply constraints continued to negatively impact our financial results, we experienced strong demand for our products and services, especially in the Cloud vertical.

We remain confident in our strategy and we are executing against our innovation roadmap, as each of our industry verticals transitions to cloud architectures. We believe our understanding of high-performance networking technology and cloud architecture and our strategy position us to capitalize on the industry transition to more automated, cost-efficient, scalable networks.

COVID-19 Pandemic Update

In early March 2020, COVID–19, a disease caused by a novel strain of a coronavirus, was characterized as a pandemic by the World Health Organization. Since December 2019, COVID-19 has spread rapidly, with confirmed cases in most countries and territories worldwide, and a high concentration of cases in the United States and many other countries in which we operate. The rapid spread has resulted in authorities around the world implementing numerous measures to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders, and business shutdowns. The COVID-19 pandemic and these containment measures have had, and are expected to continue to have, a substantial negative impact on businesses around the world and on global, regional, and national economies.

Our priorities and actions during the COVID-19 pandemic remain focused on protecting the health and safety of all those we serve – our employees, our customers, our suppliers, and our communities, including implementing early and regular updates to our health and safety policies and processes. In March 2020, we successfully migrated all but a limited number of our global workforce to work remotely while local and state governments have imposed shelter-in-place orders in the United States and around the world. We have built a valuable team over the years, and we are focused on providing them with the resources that they need to meet the needs of our customers and deliver new innovations to the markets we serve, despite challenges introduced by the COVID-19 pandemic. Beginning on May 31, 2020, we introduced a four-phased approach to reopening our offices around the world. In phase one, fewer than 5 percent of local employees are working at any given individual office. When phase four is implemented, an office will be fully operational. We are currently in phases one, two or three in various office locations around the world. We continue to follow the guidance of local and national governments, including monitoring the health of our employees who have returned to our offices, limiting the gathering size of employee groups in indoor spaces per social distancing guidelines, and requiring those employees to wear masks and to have their temperature taken upon entering our offices.

We continue to support healthy customer demand for our products by working with our suppliers and distributors to address supply chain disruptions as well as travel restrictions that have impacted our operations. We are supporting our communities by helping the medical professionals on the front-line fight against COVID-19 by donating secure wireless connectivity kits to pop-up field hospitals. We also continue to give back to the community through the Juniper Foundation, which is working to support those in need due to the COVID-19 pandemic.

We have a global supply chain footprint with our primary manufacturing partners located in China, Taiwan, Malaysia, Mexico and the United States. Our component suppliers are more geographically distributed with vendors from many countries throughout the world. During the first half of 2020, the supply constraints we experienced were due to both constrained manufacturing capacity as well as component parts shortages as our component vendors were also facing manufacturing challenges. These challenges resulted in extended lead-times to our customers, increased logistics costs, and impacted the volume of product we were able to deliver, which negatively impacted our ability to recognize the associated revenue in the first half of 2020.

Challenges to our supply chain due to the impact of the COVID-19 pandemic remain dynamic; however, we have seen improvements in our manufacturing capacity during the second quarter of 2020. We expect several of our component suppliers to remain challenged throughout most of the third quarter as they are operating under restricted work conditions. However, the impact is expected to be

34

less adverse than the first half of 2020. While COVID-19 has brought unprecedented challenges, we believe that we have a robust and fairly flexible supply chain. Our supply chain team has been working to meet our customer needs by executing on a strong risk mitigation plan, including multi-sourcing, pre-ordering components, transforming our logistics network, prioritizing critical customers, working with local government agencies to understand challenges, and partnering on solutions that limit disruptions to our operations while ensuring the safety of our employees, partners and suppliers.

The COVID-19 pandemic did not have a substantial net impact to our consolidated operating results or our liquidity position in the first half of the year. We continue to generate operating cash flows to meet our short-term liquidity needs, and we expect to maintain access to the capital markets enabled by our strong credit ratings. To date, we have not observed any material impairments of our assets or a significant change in the fair value of assets due to the COVID-19 pandemic.

We entered the third quarter with strong backlog in our Cloud and Service Provider verticals. We intend to continue to work with government authorities and implement safety measures to ensure that we are able to continue manufacturing and distributing our products during the COVID-19 pandemic. However, uncertainty resulting from the pandemic could result in an unforeseen disruption to our supply chain and logistics network that could adversely impact our operations.

We may continue to experience constrained supply and increased logistics costs and could experience curtailed customer demand, any of which could adversely impact our business, results of operations and overall financial performance in future periods.

• Net Revenues: Net revenues decreased during the three months ended June 30, 2020, compared to the same period in 2019, primarily due to the Service Provider and Enterprise verticals. Net revenues decreased during the six months ended June 30, 2020, compared to the same period in 2019, primarily due to the Service Provider vertical, partially offset by growth in Cloud and Enterprise. We believe the decline in the Service Provider vertical is partially due to COVID-19. Our Cloud vertical grew year-over-year, primarily driven by routing. The completion of the MX to PTX transition contributed toward routing growth in the Cloud vertical. Service net revenues increased during the three and six months ended June 30, 2020, compared to the same periods in 2019, primarily due to strong sales of support contracts.

Of our top ten customers for the second quarter of 2020, six were in Cloud, three were in Service Provider, and one was in Enterprise. Of these customers, one was located outside of the U.S.

• Gross Margin: The gross margin as a percentage of net revenues decreased primarily due to increased logistics and other supply chain-related costs related to the COVID-19 pandemic and certain new strategic opportunities, partially offset by higher service revenues.

• Operating Margin: The operating income as a percentage of net revenues increased primarily due to lower restructuring costs, partially offset by the drivers described in the gross margin discussion above and higher personnel-related expenses driven by an increase in headcount.

• Operating Cash Flows: Net cash provided by operations increased primarily due to lower payments to suppliers and for taxes.

36

• Capital Return: We continue to return capital to our stockholders. During the fourth quarter of 2019, we entered into an accelerated share repurchase program (the "ASR"), to repurchase an aggregate of $200.0 million in shares. Under the ASR, we made an up-front payment of $200.0 million and received and retired 6.4 million shares of our common stock during the fourth quarter of 2019. During the first quarter of 2020, the ASR was completed, and we received and retired an additional 1.8 million shares for a total repurchase of 8.2 million shares of our common stock. During the first quarter of 2020, we also repurchased 8.5 million shares of our common stock in the open market at an average price of $23.70 per share for an aggregate purchase price of $200.0 million. During the second quarter of 2020, we paid quarterly dividends of $0.20 per share, for an aggregate amount of $66.3 million.

• DSO: DSO is calculated as the ratio of ending accounts receivable, net of allowances, divided by average daily net revenues for the preceding 90 days. DSO increased primarily due to higher accounts receivable as of June 30, 2020, compared to June 30, 2019.

• Deferred Revenue: Total deferred revenue decreased as of June 30, 2020, compared to December 31, 2019, primarily due to the timing of the delivery of contractual commitments.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. On an ongoing basis, we evaluate our estimates and assumptions. These estimates and assumptions are based on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances to determine reported amounts of assets, liabilities, revenues, and expenses that are not readily apparent from other sources.

During the six months ended June 30, 2020, there were no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in Management's Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Form 10-K.

Recent Accounting Pronouncements

See Note 1, Basis of Presentation and Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report, for a full description of the recently adopted accounting standards and recent accounting standards not yet adopted, including the actual and expected dates of adoption and estimated effects on our consolidated results of operations and financial condition, which is incorporated herein by reference.

Three Months Ended June 30, 2020 compared with the Three Months Ended June 30, 2019

Product net revenues decreased primarily due to decreases in routing and switching.

Routing revenue decrease was primarily driven by Enterprise and to a lesser extent, Service Provider, from lower net revenues in our PTX product family, which was partially impacted by COVID-19 related supply constraints. The decrease was partially offset by strength in Cloud.

Switching revenue decrease was primarily driven by Cloud vertical resulting from lower net revenues in our QFX product family, which was partially offset by an increase in Service Provider vertical resulting from higher net revenues in our Mist and EX product family.

Service revenues increased primarily driven by Enterprise and Cloud due to strong sales of support contracts.

38

Six Months Ended June 30, 2020 compared with the Six Months Ended June 30, 2019

Product net revenues decreased primarily due to Service Provider and Enterprise, impacting routing, partially offset by Cloud.

Routing revenue decreased primarily driven by Service Provider and to a lesser extent, Enterprise, from lower net revenues in our MX and PTX product family, which was partially impacted by COVID-19 related supply constraints. The decrease was partially offset by strength in Cloud.

Switching revenue increased from all verticals primarily from QFX and Mist product family.

Service net revenues increased primarily due to strong sales of support contracts.

Gross Margins

The following table presents gross margins (in millions, except percentages):

	Three Months Ended June 30,											Six Months Ended June 30,
	2020			2019			$ Change			% Change		2020			2019			$ Change			% Change
Product gross margin	$	370.6		$	399.6		$	(29.0	)	(7	)%	$	710.4		$	748.3		$	(37.9	)	(5	)%
Percentage of product revenues	53.5		%	56.0		%						54.6		%	56.2		%
Service gross margin	249.0			237.2			11.8			5	%	488.5			470.8			17.7			4	%
Percentage of service revenues	63.2		%	61.0		%						62.4		%	61.0		%
Total gross margin	$	619.6		$	636.8		$	(17.2	)	(3	)%	$	1,198.9		$	1,219.1		$	(20.2	)	(2	)%
Percentage of net revenues	57.0		%	57.8		%						57.5		%	57.9		%

Our gross margins as a percentage of net revenues have been and will continue to be affected by a variety of factors, including the mix and average selling prices of our products and services, new product introductions and enhancements, manufacturing, component and logistics costs, expenses for inventory obsolescence and warranty obligations, cost of support and service personnel, customer mix as we continue to expand our footprint with certain strategic customers, the mix of distribution channels through which our products and services are sold, and import tariffs. For example, we are subject to tariffs on networking products imported from China, which includes certain products that we import into and sell within the United States. In addition, our logistics and other supply chain-related costs have increased due to COVID-19. For more information on the potential impact of tariffs and COVID-19 on our business, see the “Risk Factors” section of Item 1A of Part II of this Report.

Three Months Ended June 30, 2020 compared with the Three Months Ended June 30, 2019

Product gross margin

Product gross margin as a percentage of product revenues decreased primarily due to increased logistics and other supply chain-related costs related to the COVID-19 pandemic and certain strategic insertion opportunities. We continue to undertake specific efforts to address certain factors impacting our product gross margin. These efforts include performance and quality improvements through engineering to increase value across our products; optimizing our supply chain and service business; pricing management; and increasing software and solution sales.

Service gross margin

Service gross margin as a percentage of service net revenues increased primarily due to lower delivery costs and higher revenue.

39

Six Months Ended June 30, 2020 compared with the Six Months Ended June 30, 2019

Product gross margin

Three Months Ended June 30, 2020 compared with the Three Months Ended June 30, 2019

Total operating expenses decreased primarily due to lower restructuring charges. The remaining decrease was primarily due to lower sales and marketing, or S&M, costs related to travel-related expenses due to the impact of COVID-19, and lower research and development, or R&D, costs related to share-based compensation. The decrease in total operating expenses was partially offset by higher personnel-related expenses, specifically in R&D and S&M, driven by an increase in headcount.

Six Months Ended June 30, 2020 compared with the Six Months Ended June 30, 2019

Total operating expenses decreased primarily due to lower restructuring charges and lower travel-related expenses, specifically in S&M, due to the impact of COVID-19. Our general and administrative expenses decreased primarily because there were costs related to the acquisition of Mist Systems incurred in the second quarter of 2019. The decrease in total operating expenses was partially offset by higher personnel-related expenses, specifically in R&D and S&M, driven by an increase in headcount.

N/M - Not meaningful

Three Months Ended June 30, 2020 compared with the Three Months Ended June 30, 2019

Total other expense, net decreased slightly primarily due to gains on certain equity investments and lower interest expense as a result of lower debt balance. This was partially offset by lower interest income related to our fixed income investment portfolio, as a result of lower yields and from a lower average portfolio balance.

Six Months Ended June 30, 2020 compared with the Six Months Ended June 30, 2019

Total other expense, net increased primarily due to a decrease in interest income related to our fixed income investment portfolio, as a result of lower yields from a lower average portfolio balance. This was partially offset by a decrease in interest expense as a result of a lower debt balance.

Income Tax Provision

The following table presents income tax provision (in millions, except percentages):

	Three Months Ended June 30,											Six Months Ended June 30,
	2020			2019			$ Change			% Change		2020			2019			$ Change			% Change
Income tax provision	$	24.9		$	31.6		$	(6.7	)	(21	)%	$	32.8		$	45.0		$	(12.2	)	(27	)%
Effective tax rate	28.9		%	40.6		%						28.7		%	36.8		%

The effective tax rate decreased during the three and six months ended June 30, 2020, compared to the same period in 2019, primarily due to a change in the level of discrete items in the comparative period. For further explanation of our income tax provision, see Note 11, Income Taxes, in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report.

Our effective tax rate may fluctuate significantly on a quarterly basis and may be adversely affected to the extent earnings are lower than anticipated in countries that have lower statutory rates and higher than anticipated in countries that have higher statutory rates. Our effective tax rate may also fluctuate due to changes in the valuation of our deferred tax assets or liabilities, or by changes in tax laws, regulations, or accounting principles, as well as certain discrete items. See Item 1A of Part I, "Risk Factors" of this Report for a description of relevant risks which may adversely affect our results.

As a result of recommendations by the Organisation for Economic Co-operation and Development ("OECD") on Base Erosion and Profit Shifting, certain countries in EMEA and APAC have either enacted new corporate tax legislation or are considering enacting such legislation in the near future. We expect the effect of these reform measures to potentially impact long-standing tax principles, particularly in regard to transfer pricing. Consequently, we expect global tax authorities to increasingly challenge our cost sharing and other intercompany arrangements, and the related sourcing of taxable profits in global jurisdictions.

Net cash used in financing activities	$	(304.7	)	$	(755.8	)	$	451.1	(60	)%

Operating Activities

Net cash provided by operations increased primarily due to lower payments to suppliers and for taxes.

Investing Activities

Net cash provided by investing activities was $189.5 million during the six months ended June 30, 2020, compared to net cash used in investing activities of $556.9 million for the same period in 2019. During the six months ended June 30, 2020, the net proceeds from sales, maturities and redemptions of investments was $233.5 million. During the six months ended June 30, 2019, the payment for the acquisition of Mist was $270.9 million and net purchase of investments was $230.8 million.

Financing Activities

Net cash used in financing activities decreased during the six months ended June 30, 2020, compared to the same period in 2019, primarily due to the payments of $200.0 million under the 2018 Stock Purchase Program during the six months ended June 30, 2020 compared to the payment of $350.0 million for our Senior Notes maturity and the payment of $300.0 million pursuant to the ASR entered in April 2019 during the six months ended June 30, 2019.

Capital Return

In January 2018, our Board of Directors, which we refer to as the Board, approved a $2.0 billion share repurchase program to replace our prior authorization, which we refer to as the 2018 Stock Repurchase Program. In October 2019, the Board authorized a $1.0 billion increase to the 2018 Stock Repurchase Program for a total of $3.0 billion.

In October 2019, we entered into an ASR, to repurchase an aggregate of approximately $200.0 million of our outstanding common stock. During the three months ended December 31, 2019, we made an up-front payment of $200.0 million pursuant to the ASR and received and retired an initial 6.4 million shares of our common stock for an aggregate price of $160.0 million, based on the market price of $25.15 per share of our common stock on the date of the transaction. During the three months ended March 31, 2020, the ASR was completed, and an additional 1.8 million shares were received for a total repurchase of 8.2 million shares of our common stock at a volume weighted average repurchase price of $24.44 per share, net of an agreed upon discount. The shares received by us were retired, accounted for as a reduction to stockholder’s equity in the Condensed Consolidated Balance Sheets, and treated as a repurchase of common stock for purposes of calculating earnings per share.

During the first quarter of 2020, we also repurchased 8.5 million shares of our common stock in the open market for an aggregate purchase price of $200.0 million at an average price of $23.70 per share.

As of June 30, 2020, there was approximately $1.5 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

Future share repurchases under the 2018 Stock Repurchase Program will be subject to a review of the circumstances at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. Our 2018 Stock Repurchase Program does not have a specified termination date, but may be discontinued at any time. See Note 8, Equity, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report for further discussion of our share repurchase program. While we expect to remain opportunistic with respect to share repurchases, we expect to place a greater emphasis on further building liquidity in the short-term.

We declared and paid a quarterly cash dividend of $0.20 per share, totaling $66.3 million and $131.8 million during the three and six months ended June 30, 2020, respectively. Although we remain committed to paying our dividend, any future dividends, and the establishment of record and payment dates, are subject to approval by the Board or an authorized committee thereof. See Note 14, Subsequent Events, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report for discussion of our dividend declaration subsequent to June 30, 2020.

Revolving Credit Facility

We have an unsecured revolving credit facility, which enables borrowings of up to $500.0 million, with an option to increase the amount of the credit facility by up to an additional $200.0 million, subject to the lenders' approval. The credit facility will terminate in April 2024, subject to a one-year maturity extension option. As of June 30, 2020, we were in compliance with all covenants and no amounts were outstanding under our credit facility.

Liquidity and Capital Resource Requirements

Liquidity and capital resources may be impacted by our operating activities as well as acquisitions, investments in strategic relationships, repurchases of additional shares of our common stock, and payment of cash dividends on our common stock. Since the enactment of the Tax Cuts and Jobs Act (the “Tax Act”), we have repatriated a significant amount of cash, cash equivalents, and investments from outside of the U.S., and plan to continue to repatriate on an ongoing basis, subject to our consideration of strategic overseas investments. We intend to use the repatriated cash to invest in the business, support value-enhancing merger and acquisitions, or M&A, and fund our return of capital to stockholders.

Based on past performance and current expectations, we believe that our existing cash and cash equivalents, short-term, and long-term investments, together with cash generated from operations and access to capital markets and the revolving credit facility will be sufficient to fund our operations; planned stock repurchases and dividends; capital expenditures; commitments and other liquidity requirements; and anticipated growth for at least the next twelve months. However, our future liquidity and capital requirements may vary materially from those now planned depending on many factors, including, but not limited to, our growth rate; the timing and amount we spend to support development efforts; the expansion of sales and marketing activities; the introduction of new and enhanced products and services; the costs to acquire or invest in businesses and technologies; an increase in manufacturing or component costs; and the risks and uncertainties detailed in the “Risk Factors” section of Item 1A of Part II of this Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our exposures to market risk have not changed materially since December 31, 2019. For quantitative and qualitative disclosures about market risk, see Item 7A Quantitative and Qualitative Disclosures about Market Risk, in our Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Attached as exhibits to this Report are certifications of our principal executive officer and principal financial officer, which are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This “Controls and Procedures” section includes information concerning the controls and related evaluations referred to in the certifications and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

We carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered in this Report, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls Over Financial Reporting

There were no changes in our internal control over financial reporting during the second quarter of 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any significant impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. The design of our processes and controls allow for remote execution with accessibility to secure data. We are continually monitoring and assessing the COVID-19 situation to minimize the impact, if any, on the design and operating effectiveness on our internal controls.

Item 1. Legal Proceedings

The information set forth under the “Legal Proceedings” section in Note 13, Commitments and Contingencies, in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report, is incorporated herein by reference.

Item 1A. Risk Factors

Factors That May Affect Future Results

Investments in our securities involve significant risks. Even small changes in investor expectations for our future growth and earnings, whether as a result of actual or rumored financial or operating results, changes in the mix of the products and services sold, acquisitions, industry changes, or other factors, including, but not limited to, the effects of the COVID-19 pandemic, could trigger, and have triggered in the past, significant fluctuations in the market price of our common stock. Investors in our securities should carefully consider all of the relevant factors disclosed by us, including, but not limited to, the following factors that could affect our business, operating results, and stock price.

The effects of the COVID-19 pandemic have significantly affected how we and our customers are operating our businesses, and the duration and extent to which this will impact our future results of operations and overall financial performance remains uncertain.

The COVID-19 pandemic has resulted in a widespread health crisis that is adversely affecting the broader economies, financial markets and may affect the overall demand environment for our products and services.

As a result of the COVID-19 pandemic, our operations have been negatively affected by a range of external factors that are not within our control. For example, most U.S. states and countries worldwide have imposed and may continue to impose from time-to-time for the foreseeable future, a wide range of restrictions on the physical movement of our employees, partners, and customers to limit the spread of COVID-19, including travel restrictions and shelter-in-place orders. In March 2020, we requested all but a limited number of our global workforce to work remotely while shelter-in-place requirements and travel restrictions are in effect, all of which have changed how we operate our business. Beginning May 31, 2020, we introduced a four-phased approach to reopening our offices around the world. In phase one, fewer than 5 percent of local employees are working at an individual office. When phase four is implemented, any given individual office will be fully operational with all employees on site. We are currently in phases one, two or three in various locations around the world. We continue to follow the guidance of local and national governments, including monitoring the health of our employees who have returned to our offices, limiting the gathering size of employee groups in indoor spaces per social distancing guidelines, and requiring those employees to wear masks and to have their temperature taken upon entering our offices. If the COVID-19 pandemic has a substantial impact on our employees, partners or customers health, attendance or productivity, our results of operations and overall financial performance may be adversely impacted.

Moreover, the conditions caused by the COVID-19 pandemic could adversely affect our customers’ ability or willingness to purchase our products or services or to make payments on existing contracts with us, delay prospective customers’ purchasing decisions, delay the provisioning of our offerings, lengthen payment terms, or affect attrition rates, all of which could adversely affect our future sales, operating results and overall financial performance. Further, the COVID-19 pandemic has adversely affected and could continue to adversely affect our ability to provide or deliver products and on-site services to our customers. For example, during the second quarter of fiscal 2020, the COVID-19 pandemic continued to cause us to experience supply constraints due to both constrained manufacturing capacity as well as component parts shortages as our component vendors were also facing manufacturing challenges. These challenges resulted in extended lead-times to our customers and had a negative impact on our ability to recognize associated revenue first half of 2020. While the situation remains very dynamic, our manufacturing capacity has improved in the second quarter of fiscal 2020. However, we expect several of our component suppliers will remain challenged throughout most of the third quarter as they continue to operate under restricted work conditions.

While the potential economic impact brought by the COVID-19 pandemic may be difficult to assess or predict, the pandemic has resulted in significant disruption of global financial markets and on June 8, 2020, the National Bureau of Economic Research announced that the U.S. was in a recession. A long-term recession or market downturn could materially impact the value of our common stock, impact our access to capital and affect our business in the near and long-term.

The duration and extent of the impact from the COVID-19 pandemic on our business depends on future developments that cannot be accurately forecasted at this time, such as the transmission rate and geographic spread of the disease, the extent and effectiveness

46

of containment actions and the impact of these and other factors on our employees, suppliers, customers, partners, and vendors. If we are not able to respond to and manage the impact of such events effectively and if the macroeconomic conditions of the general economy or the industries in which we operate do not improve, or worsen from present levels, our business, operating results, financial condition and cash flows could be adversely affected.

Our quarterly results are unpredictable and subject to substantial fluctuations; as a result, we may fail to meet the expectations of securities analysts and investors, which could adversely affect the trading price of our common stock.

Our revenues and operating results may vary significantly from quarter-to-quarter due to a number of factors, many of which are outside of our control and any of which may cause our stock price to fluctuate.

The factors that may cause our quarterly results to vary quarter by quarter and be unpredictable include, but are not limited to:

• unpredictable ordering patterns and limited or reduced visibility into our customers’ spending plans and associated revenue;

• changes in customer mix;

• changes in the demand for our products and services;

• changes in the mix of products and services sold;

• changes in the mix of geographies in which our products and services are sold;

• changing market and economic conditions, including the impacts due to tariffs and the COVID-19 pandemic;

• current and potential customer, partner and supplier consolidation, concentration, and economic disruption;

• price and product competition;

• long sales, qualification and implementation cycles;

• success in new and evolving markets and emerging technologies;

• ineffective legal protection of our intellectual property rights in certain countries;

• how well we execute on our strategy and operating plans and the impact of changes in our business model that could result in significant restructuring charges;

• ability of our customers, channel partners, contract manufacturers and suppliers to purchase, market, sell, manufacture or supply our products (or components of our products) and services, including as a result of disruptions arising from the COVID-19 pandemic;

• financial stability of our customers, including the solvency of private sector customers, which may be impacted by the COVID-19 pandemic and statutory authority for government customers to purchase goods and services;

• our ability to achieve targeted gross margins and operating expenses;

• executive orders, changes in laws or regulations, or interpretations thereof;

• changes in accounting rules, or interpretations thereof;

• changes or suspensions in the amount and frequency of share repurchases or dividends;

• regional economic and political conditions which may be aggravated by unanticipated global events;

• increasing cyber-security threats to our internal network and those of our suppliers, partners, and customers;

• seasonality;

• factors beyond our control resulting from public health epidemics, pandemics and similar outbreaks as well as the fear of exposure to a widespread health epidemic, such as the COVID-19 pandemic, manufacturing restrictions, travel restrictions and shelter-in-place orders to control the spread of a disease regionally and globally, and limitations on the ability of our employees and our supplier's and customer's employees to work and travel; and

• other factors beyond our control such as the effects of global or regional economic instability, investment performance, climate change, natural or man-made disasters, political unrest, hostilities and armed conflict within or among countries, acts of terrorism. or other unanticipated extraordinary externalities that may affect the global economy and could have a material adverse effect on the Company's business, results of operations and financial condition.

For example, we, and many companies in our industry, traditionally experience adverse seasonal fluctuations in customer spending. In addition, while we may have backlog orders for products that have not shipped, we believe that our backlog may not be a reliable indicator of future operating results for a number of reasons, including, but not limited to, project delays, changes in project scope and the fact that our customers may cancel purchase orders or change delivery schedules without significant penalty, and the potential negative impacts related to the global spread of COVID-19.

Furthermore, market trends, competitive pressures, commoditization of products, rebates and discounting, increased component, manufacturing or logistics costs or supply chain disruptions, issues with product or service quality (including the quality of our components), regulatory impacts, tariffs and other factors beyond our control, including the rapidly evolving global COVID-19 pandemic, which may result in reductions in revenue or pressure on gross margins in a given period, and may necessitate adjustments to our operations. Such adjustments may be difficult or impossible to execute in the short or medium term.

47

As a result of the factors described above, as well as other variables affecting our operating results, we believe that quarter-to-quarter comparisons of operating results are not necessarily a good indication of what our future performance will be. In some prior periods, our operating results (or portions of our operating results) have been below our guidance, our long-term financial model or the expectations of securities analysts or investors, which has at times coincided with a decline in the price of our common stock. This may happen again in the future, in which case the price of our common stock may decline. Such a decline could also occur, and has occurred in the past, even when we have met our publicly stated revenues and/or earnings guidance.

We expect our gross margins and operating margins to vary over time.

We expect our product and service gross margins to vary, both in the near-term and in the long-term, and may be adversely affected in the future by numerous factors, some of which have occurred and may occur in the future, including customer, vertical, product and geographic mix shifts, an increase or decrease in our software sales or services we provide, increased price competition in one or more of the markets in which we compete, changes in the actions of our competitors or their pricing strategies, which may be difficult to predict and respond to, modifications to our pricing strategy in order to gain footprint in certain markets or with certain customers, currency fluctuations that impact our costs or the cost of our products and services to our customers, increases in material, labor, logistics, warranty costs, or inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, issues with manufacturing or component availability, issues relating to the distribution of our products and provision of our services, quality or efficiencies, increased costs due to changes in component pricing or charges incurred due to inaccurately forecasting product demand, warranty related issues, the impact of tariffs, or our introduction of new products and enhancements or entry into new markets with different pricing and cost structures. For example, in fiscal year 2019, our gross margin was relatively flat as compared to fiscal year 2018. In fiscal year 2018, our margins decreased as compared to fiscal year 2017, primarily due to lower net revenues and product mix. In fiscal year 2017, our margins decreased as compared to fiscal year 2016, primarily due to lower product net revenues and product mix, resulting from the year-over-year decline in routing revenues, our customers' architectural shifts, and higher costs of certain memory components. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.

A limited number of our customers comprise a material portion of our revenues and any changes in the way they purchase products and services from us could affect our business. In addition, there is an ongoing trend toward consolidation in the industry in which our customers and partners operate. Any decrease in revenues from our customers or partners could have an adverse effect on our net revenues and operating results.

A material portion of our net revenues, across each customer vertical, depends on sales to a limited number of customers and distribution partners. Changes in the business requirements or focus, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased or delays in deployment) of our key customers could significantly decrease our sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.

In addition, in recent years, there has been a movement towards consolidation in the telecommunications industry (for example, CenturyLink, Inc.'s acquisition of Level 3 Communications, Inc., Vodafone India’s acquisition of Idea Cellular Ltd. and T-Mobile US, Inc.'s acquisition of Sprint Corp.) and that consolidation trend has continued. Certain telecommunications companies have also moved towards vertical consolidation through acquisitions of media and content companies, such as Verizon’s acquisitions of Yahoo and BlueJeans, AT&T’s acquisition of Time Warner, and Comcast's acquisition of Sky. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other direct or indirect unforeseen consequences could harm our business, financial condition, and results of operations.

Fluctuating economic conditions make it difficult to predict revenues and gross margin for a particular period and a shortfall in revenues or increase in costs of production may harm our operating results.

Our revenues and gross margin depend significantly on general economic conditions and the demand for products in the markets in which we compete. Economic weakness or uncertainty, customer financial difficulties, and constrained spending on network expansion and enterprise infrastructure have in the past resulted in, and may in the future result in, decreased revenues and earnings. Such factors could make it difficult to accurately forecast revenues and operating results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers and manage our contract manufacturer relationships and other expenses. In addition, economic instability or uncertainty, continued turmoil in the geopolitical environment in many parts of the world and other events beyond our control, such as the COVID-19 pandemic, have, and may continue to, put pressure on economic conditions, which has led and could lead, to reduced demand for our products, to delays or reductions in network expansions or infrastructure

48

projects, and/or higher costs of production. More generally speaking, economic weakness may also lead to longer collection cycles for payments due from our customers, an increase in customer bad debt, restructuring initiatives and associated expenses, and impairment of investments. Furthermore, instability in the global markets may adversely impact the ability of our customers to adequately fund their expected expenditures, which could lead to delays or cancellations of planned purchases of our products or services. Our operating expenses are largely based on anticipated revenue trends and a high percentage of our expenses is, and will continue to be, fixed in the short and medium term. Uncertainty about future economic conditions also makes it difficult to forecast operating results and to make decisions about future investments. Future or continued economic weakness, failure of our customers and markets to recover from such weakness, customer financial difficulties, increases in costs of production, and reductions in spending on network maintenance and expansion could result in price concessions in certain markets or have a material adverse effect on demand for our products and consequently on our business, financial condition, and results of operations.

Our success depends upon our ability to effectively plan and manage our resources, and restructure our business through rapidly fluctuating economic and market conditions, and such actions may have an adverse effect on our financial and operating results.

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business and business models in response to fluctuating market opportunities and conditions.

From time to time, we have increased investment in our business by, for example, increasing headcount, acquiring companies, and increasing our investment in R&D, sales and marketing, and other parts of our business. Conversely, in the last few years and in 2020, we have initiated restructuring plans to realign our workforce as a result of organizational and leadership changes, align our execution priorities, increase operational efficiencies, and consolidate facilities, which resulted in restructuring charges. Some of our expenses related to such efforts are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or numbers of employees. Rapid changes in the size, alignment or organization of our workforce, including sales account coverage, could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business and financial objectives. Our ability to achieve the anticipated cost savings and other benefits from our restructuring initiatives within the expected time frame is subject to many estimates and assumptions, which are subject to significant economic, competitive, and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.

We face intense competition that could reduce our revenues and adversely affect our business and financial results.

Competition is intense in the markets that we serve. The routing and switching markets have historically been dominated by Cisco with competition coming from other companies such as Nokia, Arista, and Huawei. In the security market, we face intense competition from Cisco and Palo Alto Networks, as well as companies such as Check Point and Fortinet. Further, a number of other small public and private companies have products or have announced plans for new products to address the same challenges and markets that our products address.

In addition, actual or speculated consolidation among competitors, or the acquisition by, or of, our partners and/or resellers by competitors can increase the competitive pressures faced by us as customers may delay spending decisions or not purchase our products at all. A number of our competitors have substantially greater resources and can offer a wider range of products and services for the overall network equipment market than we do. In addition, some of our competitors have become more integrated, including through consolidation and vertical integration, and offer a broader range of products and services, which could make their solutions more attractive to our customers. Many of our competitors sell networking products as bundled solutions with other IT products, such as computer and storage systems. If we are unable to compete successfully against existing and future competitors on the basis of product offerings or price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could reduce our gross margins, and which could materially and adversely affect our business, financial condition, and results of operations. Our partners and resellers generally sell or resell competing products on a non-exclusive basis and consolidation could delay spending or require us to increase discounts to compete, which could also adversely affect our business.

The long sales and implementation cycles for our products, as well as our expectation that some customers will sporadically place large orders with short lead times, may cause our revenues and operating results to vary significantly from quarter-to-quarter.

A customer's decision to purchase certain of our products, particularly new products, involves a significant commitment of its resources and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular,

49

customers making critical decisions regarding the design and implementation of large network deployments may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the sales cycle, we may spend considerable time educating and providing information to prospective customers regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy our products slowly and deliberately. Timing of deployment can vary widely and depends on the skill set of the customer, the size of the network deployment, the complexity of the customer's network environment, and the degree of hardware and operating system configuration necessary to deploy the products. Customers with large networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation that customers will tend to sporadically place large orders with short lead times, both of which may be exacerbated by the impact of global economic weakness, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.

The timing of product orders and deliveries and/or our reliance on revenue from sales of certain software or subscriptions and professional, support and maintenance services may cause us to recognize revenue in a different period than the one in which a transaction takes place.

Due to the cost, complexity, and custom nature of configurations required by our customers, a number of our network equipment products are built as orders are received. The volume of orders received late in any given fiscal quarter remains unpredictable. If orders for certain products are received late in any quarter, we may not be able to recognize revenue for these orders in the same period, which could adversely affect our ability to meet our expected revenues for such quarter. Similarly, if we were to take actions to encourage customers to place orders or accept deliveries earlier than anticipated, our ability to meet our expected revenues in future quarters could be adversely affected.

In addition, services revenue accounts for a significant portion of our revenue, comprising 35%, 33%, and 31% of total revenue in fiscal year 2019, 2018, and 2017, respectively. Sales of new or renewal professional services, support, and maintenance contracts may decline and/or fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services or those offered by our competitors, and reductions in our end-customers’ spending levels. We recognize professional services as services are delivered and support, and maintenance revenue periodically over the term of the relevant service period.

The introduction of new software products and services is part of our intended strategy to expand our software business, and certain software revenues may be recognized periodically over the term of the relevant use period or subscription period. As a result, certain software, subscription and support, and maintenance revenue we report each fiscal quarter is derived from the recognition of deferred revenue from contracts entered into during previous fiscal quarters. Consequently, any fluctuation in such new or renewed contracts in any one fiscal quarter may not be fully or immediately reflected in revenue and could negatively affect our revenue in future fiscal quarters. Accordingly, the effect of significant downturns in new or renewed sales of certain software products, subscriptions or support, and maintenance is not reflected in full in our operating results until future periods. Also, it is difficult for us to rapidly increase such software or services revenue through additional sales in any period, as revenue from those software, subscription and support, and maintenance contracts must be recognized over the applicable period.

Additionally, we determine our operating expenses based on our anticipated revenues and technology roadmap and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter.

We sell our products to customers that use those products to build networks and IP infrastructure, and if the demand for network and IP systems does not continue to grow, our business, financial condition, and results of operations could be adversely affected.

A substantial portion of our business and revenues depends on the growth of secure IP infrastructure and customers that depend on the continued growth of IP services to deploy our products in their networks and IP infrastructures. As a result of changes in the economy, capital spending or the building of network capacity in excess of demand (all of which, have in the past, particularly affected telecommunications service providers), spending on IP infrastructure can vary, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, a number of our existing customers are evaluating the build-out of their next generation networks. During the decision-making period when our customers are determining the design of those networks and the selection of the software and equipment they will use in those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. Any reduction or suspension of spending on IP infrastructure is difficult to predict, and may be due to events beyond our control, such as the COVID-19 pandemic. This, in turn, can make it more difficult to accurately predict revenues from customers, can cause fluctuations in the level of spending by customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of

50

operations.

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products, product enhancements and business strategies that meet those technological shifts, needs and opportunities, or if those products are not made available or strategies are not executed in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues will suffer.

The markets for our products are characterized by rapid technological change, frequent new product introductions, changes in customer requirements, continuous pricing pressures and a constantly evolving industry. We may not be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products, product enhancements or business strategies to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional WAN infrastructures towards software-defined WAN has been receiving considerable attention. If we fail to anticipate market requirements or opportunities or fail to develop and introduce new products, product enhancements or business strategies to meet those requirements or opportunities in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products and services, which would significantly harm our business, financial condition, and results of operations. In addition, if we invest time, energy, and resources in developing products for a market that does not develop, it could likewise significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products, enhancements or business strategies, there can be no assurance that new products, enhancements or business strategies will achieve widespread market acceptance.

In recent years, we have announced a number of new products and enhancements to our hardware and software products across routing, switching and security. The success of our new products depends on several factors, including, but not limited to, component costs, timely completion and introduction of these products, prompt resolution of any defects or bugs in these products, our ability to support these products, differentiation of new products from those of our competitors and market acceptance of these products.

The introduction of new software products is part of our intended strategy to expand our software business. We have also disaggregated certain software from certain hardware products, such that customers may purchase or license our hardware and software products independently, which we expect could in time enable our hardware to be deployed with third- party networking applications and services and our software to be used with third-party hardware. The success of our strategy to expand our software business, including our strategy to disaggregate software from certain hardware products, is subject to a number of risks and uncertainties, including:

• the additional development efforts and costs required to create new software products and/or to make our disaggregated products compatible with multiple technologies;

• the possibility that our new software products or disaggregated products may not achieve widespread customer adoption;

• the possibility that our strategy could erode our revenue and gross margins;

• the impact on our financial results of longer periods of revenue recognition for certain types of software products

and changes in tax treatment associated with software sales;

• the additional costs associated with regulatory compliance and changes we need to make to our distribution chain in connection with increased software sales;

• the ability of our disaggregated hardware and software products to operate independently and/or to integrate with current and future third-party products; and

• issues with third-party technologies used with our disaggregated products, which may be attributed to us.

If any of our new products or business strategies do not gain market acceptance or meet our expectations for growth, our ability to meet future financial targets may be adversely affected and our competitive position and our business and financial results could be harmed.

51

We are dependent on contract manufacturers and original design manufacturers with whom we do not have long-term supply contracts, and changes to or disruptions in those relationships or manufacturing processes, expected or unexpected, may result in delays that could cause us to lose revenues and damage our customer relationships.

We depend on independent contract manufacturers and original design manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers and original design manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer and original design manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer and original design manufacturer relationships, which could include failing to provide accurate forecasts of our requirements, or if one or more of them experiences delays, disruptions, or quality control problems in their manufacturing operations, or if we had to change or add additional contract manufacturers, original design manufacturers, or contract manufacturing sites, our ability to ship products to our customers could be delayed. We have experienced in the past and may experience in the future an increase in the expected time required to manufacture our products or ship products, including delays due to the manufacturing restrictions, travel restrictions and shelter-in-place orders to control the spread of COVID-19 regionally and globally. Such delays could result in supply shortfalls that damage our ability to meet customer demand for those products and could cause our customers to purchase alternative products from our competitors. Also, the addition of manufacturing locations or contract manufacturers, original design manufacturers, or the introduction of new products by us would increase the complexity of our supply chain management. Moreover, a significant portion of our manufacturing is performed in China, Malaysia and other foreign countries and is therefore subject to risks associated with doing business outside of the United States, including import tariffs, disruptions to our supply chain, pandemics such as the COVID-19 pandemic, regional climate-related events, or regional conflicts.

For example, in 2018, the United States imposed a tariff on certain networking products imported from China and in 2019, the United States increased the tariffs on these networking products and expanded the list of products subject to the tariff. Certain products that we import into and sell within the United States are included on the list of products subject to these tariffs. We have incurred increased costs due to our efforts to attempt to mitigate the impact of the tariffs. In some cases, the tariffs have been passed on and may continue to be passed on to customers resulting in higher prices for our customers, which may have reduced, or may continue to reduce, customer demand for our products. Similarly, many of the products that we source from China are transported by air cargo from Hong Kong, which has experienced recent political demonstrations that have previously resulted in cancellations or delays in flights in and out of Hong Kong. If these demonstrations impact air shipments again, we could experience delays in product deliveries or be required to change our shipping practices.

In addition, delays in production or delays in product deliveries due to the COVID-19 pandemic have adversely affected and may continue to adversely affect our business, financial condition, and results of operations. For example, during the second quarter of fiscal 2020, the COVID-19 pandemic caused us to experience supply constraints due to both constrained manufacturing capacity, particularly in China and Malaysia, as well as component parts shortages as our component vendors were also facing manufacturing challenges. These challenges resulted in extended lead-times to our customers and had a negative impact on our ability to recognize associated revenue in the second quarter. We intend to continue to work with government authorities and implement safety measures to ensure that we are able to continue manufacturing and distributing our products during the COVID-19 pandemic. However, uncertainty resulting from the pandemic could result in an unforeseen disruption to our supply chain (for example a closure of a key manufacturing or distribution facility or the inability of a key supplier or transportation supplier to source and transport materials) that could impact our operations.

We are dependent on sole source and limited source suppliers, including for key components, which makes us susceptible to shortages, quality issues or price fluctuations in our supply chain, and we may face increased challenges in supply chain management in the future.

We rely on single or limited sources for many of our components. During periods of high demand for electronic products or supply constraints by manufacturers of electronic components, component shortages are possible, and the predictability of the availability of such components may be limited. For example, we have experienced industry-wide supply constraints related to power management components. In addition, some components used in our networking solutions have in the past and may in the future experience extended lead times and higher pricing, given the demand in the market. Any future spike in growth in our business, the use of certain components we share in common with other companies, in IT spending or the economy in general, is likely to create greater short-term pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component inventories. If shortages or delays persist, we may not be able to secure enough components at reasonable prices or of acceptable quality to build and deliver products in a timely manner, and our revenues, gross margins and customer relationships could suffer. Additionally, if certain components that we receive from our suppliers have defects or other quality issues, we may have to replace or repair such components, and we could be subject to claims based on warranty, product liability,

52

epidemic or delivery failures that could lead to significant expenses. We maintain product liability insurance, but there is no guarantee that such insurance will be available or adequate to protect against all such claims. We have experienced, and from time-to-time may experience, component shortages or quality issues that resulted, or could result, in delays of product shipments, revenue charges that impact our gross margins, and/or warranty or other claims or costs. We also currently purchase numerous key components, including ASICs and other semiconductor chips, from single or limited sources and many of our component suppliers are concentrated in China and Korea. In addition, there has been consolidation among certain suppliers of our components. For example, GLOBALFOUNDRIES acquired IBM’s semiconductor manufacturing business, Avago Technologies Limited acquired Broadcom Corporation, Intel Corporation acquired Altera Corporation ("Altera"), and Cisco acquired Acacia Communications, Inc. Consolidation among suppliers can result in the reduction of the number of independent suppliers of components available to us, which could negatively impact our ability to access certain component parts or the prices we have to pay for such parts, which may impact our gross margins. In addition, our suppliers may determine not to continue a business relationship with us for other reasons that may be beyond our control or may seek to impose significant price increases. Any disruptions to our supply chain or significant increase in components cost could decrease our sales, earnings and liquidity or otherwise adversely affect our business and result in increased costs. Such a disruption could occur as a result of any number of events, including, but not limited to, an extended closure of or any slowdown at our supplier's plants or shipping delays due to efforts to limit the spread of COVID-19, increases in wages that drive up prices, the imposition of regulations, quotas or embargoes on components, labor stoppages, transportation failures affecting the supply chain and shipment of materials and finished goods, third-party interference in the integrity of the products sourced through the supply chain, the unavailability of raw materials, severe weather conditions, adverse effects of climate change, natural disasters, civil unrest, military conflicts, geopolitical developments, war or terrorism and disruptions in utility and other services.

The development of alternate sources for components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Also, long-term supply and maintenance obligations to customers increase the duration for which specific components are required, which may further increase the risk of component shortages or the cost of carrying inventory. In the event of a component shortage, supply interruption or significant price increase from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver products and services to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.

In addition, the development, licensing, or acquisition of new products in the future may increase the complexity of supply chain management. Failure to effectively manage the supply of components and products would adversely affect our business.

If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience manufacturing delays, which would harm our business.

We provide demand forecasts for our products to our contract manufacturers and original design manufacturers, who order components and plan capacity based on these forecasts. If we overestimate our requirements, our original design or contract manufacturers may assess charges, or we may have liabilities for excess inventory, each of which could negatively affect our gross margins. For example, in certain prior quarters, our gross margins were reduced as a result of an inventory charge resulting from inventory we held in excess of forecasted demand. In addition, some optical modules we use are experiencing faster product transitions than our other products, which increases the risk that we could have excess inventory of those modules. Conversely, lead times for required materials and components vary significantly and depend on factors such as the specific supplier, contract terms, and the demand for each component at a given time, which may be affected by external factors, including the impact of the COVID-19 pandemic. Given that our contract manufacturers are third-party manufacturers for numerous other companies, if we underestimate our requirements, as we have in certain prior quarters with respect to certain products, our contract manufacturers may have inadequate time, materials, and/or components required to produce our products. This could increase costs or delay or interrupt manufacturing of our products, resulting in delays in shipments and deferral or loss of revenues and could negatively impact customer satisfaction.

System security risks, data protection breaches, and cyber-attacks could compromise our and our customers’ proprietary information, disrupt our internal operations and harm public perception of our products, which could cause our business and reputation to suffer and adversely affect our stock price.

In the ordinary course of business, we store sensitive data, including intellectual property, personal data, our proprietary business information and that of our employees, contractors, customers, suppliers and business partners on our networks. In addition, we store sensitive data through cloud-based services that may be hosted by third parties and in data center infrastructure maintained by third parties. The secure maintenance of this information is critical to our operations and business strategy. The growing cyber

53

risk environment means that individuals, companies, and organizations of all sizes, including Juniper, have been and are increasingly subject to attacks and attempted intrusions, including recent attempts, on their and their vendors' networks and systems by a wide range of actors, including but not limited to nation states, criminal enterprises, and terrorist organizations, on an ongoing and regular basis.

Despite our security measures, and those of our third-party vendors, our information technology and infrastructure has experienced breaches and may be subject or vulnerable in the future to breaches or attacks by computer programmers, hackers or sophisticated nation-state and nation-state supported actors or breaches due to employee error or wrongful conduct, malfeasance, or other disruptions. If any breach or attack compromises our networks or those of our vendors, creates system disruptions or slowdowns or exploits security vulnerabilities of our products, the information stored on our networks or those of our customers, suppliers or business partners could be accessed and modified, publicly disclosed, lost, destroyed or stolen, and we may be subject to claims for contractual, tort or equitable liability from our customers, suppliers, business partners and others, including regulatory entities, and suffer reputational and financial harm. In addition, hardware, components and software (including operating system software) and applications that we develop, manufacture, or procure from third parties may contain defects in design or manufacture, including "bugs", vulnerabilities and other problems that could unexpectedly interfere with the operation of our networks, or expose us or our products to cyber attacks, or be exploited to gain unauthorized access to our or our customers’ systems and information. This can be true even for “legacy” products that have been determined to have reached an end of life engineering status but will continue to be supported for a limited amount of time. Furthermore, third parties may attempt to exfiltrate data through the introduction into the Information and Communications Technology supply chain of malicious products and components that are designed to defeat or circumvent encryption and other cybersecurity measures, and if successful, such actions could diminish customer trust in our products, harm our business reputation, and adversely affect our business and financial condition. When vulnerabilities are discovered, we evaluate the risk, apply patches or take other remediation actions and notify customers, business partners, and suppliers as appropriate. All of this requires significant resources and time and attention from management and our employees.

The COVID-19 pandemic may adversely affect our systems, and the health of members of our internal security team who monitor and address the cyber threats and attacks against Juniper. In particular, the internet is currently experiencing an increase in cyber threats during the COVID-19 pandemic in the form of phishing emails, malware attachments and malicious websites which seemingly offer information regarding COVID-19. We have employed efforts to mitigate any potential impact that could result from increased cyber threats and the loss of members of our internal security team and by providing our employees with enhanced awareness materials and training, updating our business continuity plans, and cross training staff.

As a result of any actual or perceived breach of security that occurs in our network or in the network of a customer of our products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products and our overall reputation could be harmed. As a large, well known provider of networking products, cyber attackers regularly and specifically target our products or attempt to imitate us or our products in order to compromise a network. Because the techniques used by attackers, many of whom are highly sophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unable to anticipate or immediately detect these techniques or the vulnerabilities they have caused. This could impede our sales, manufacturing, distribution or other critical functions, which could have an adverse impact on our financial results. The economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems, and security vulnerabilities could be significant and may be difficult to anticipate or measure, because the damage may differ based on the identity and motive of the attacker, which are often difficult to pinpoint.

Additionally, we could be subject to measures that regulate the security of the types of products we sell, such as the California Internet of Things (IoT) security law (SB-327), which became enforceable in 2020, which can result in increased costs and delays in product releases and changes in features to achieve compliance which may impact customer demand for our products, as well as regulatory investigations, potential fines, and litigation in connection with a compliance concern, security breach or related issue and potential liability to third parties arising from such breaches. Further, in response to actual or anticipated cybersecurity regulations or contractual security requirements negotiated with our customers, we may need to make changes to existing policies, processes and supplier relationships that could impact product offerings, release schedules and service response times which could adversely affect the demand for and sales of our products and services.

54

We rely on value-added and other resellers, as well as distribution partners, to sell our products, and disruptions to, or our failure to effectively develop and manage, our distribution channel and the processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products.

Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, Nippon Telegraph and Telephone Corporation, and NEC Corporation. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products, and some of which sell their own competing products. Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our resellers or distributors could materially reduce our revenues. Our competitors may in some cases be effective in leveraging their market share positions or in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, fail to expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, determine that we cannot continue to do business with these partners for any reason, or if these partners are not successful in their sales efforts, sales of our products may decrease, and our business, financial condition, and results of operations would suffer.

In addition, we recognize a portion of our revenues at the time we sell products to our distributors. If these sales are made based on inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted. Further, our distributors may increase orders during periods of product shortages, cancel orders if their inventory is too high, or delay orders in anticipation of new products. They also may adjust their orders in response to the supply of our products and the products of our competitors that are available to them, and in response to seasonal fluctuations in end-user demand.

We are also vulnerable to third parties who illegally distribute or sell counterfeit, stolen or unfit versions of our products, which has happened in the past and could happen in the future. Such sales could have a negative impact on our reputation and business.

Further, in order to develop and expand our distribution channel, we must continue to offer attractive channel programs to potential partners and scale and improve our processes and procedures that support the channel. As a result, our programs, processes and procedures may become increasingly complex and inherently difficult to manage. We have previously entered into OEM agreements with partners pursuant to which they rebrand and resell our products as part of their product portfolios. These types of relationships are complex and require additional processes and procedures that may be challenging and costly to implement, maintain and manage. Our failure to successfully manage and develop our distribution channel and the programs, processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products. We also depend on our global channel partners to comply with applicable legal and regulatory requirements. To the extent that they fail to do so, that could have a material adverse effect on our business, operating results, and financial condition.

Our ability to process orders and ship products in a timely manner is dependent in part on our business systems and performance of the systems and processes of third parties as well as the interfaces between our systems and the systems of such third parties. Dependence on outsourced information technology and other administrative functions may impair our ability to operate effectively.

Some of our business processes depend upon our IT systems, the systems and processes of third parties, and the interfaces between the two. For example, on December 31, 2018, we entered into a Master Services Agreement and certain Statements of Work with IBM, which was subsequently amended, pursuant to which we have outsourced significant portions of our IT and other administrative functions. These cloud providers, third party providers, and off-site facilities are vulnerable to damage, interruption, including performance problems from earthquakes, hurricanes, floods, fires, power loss, telecommunications failures, equipment failure, adverse events caused by operator error, cybersecurity attacks, pandemics (including the COVID-19 pandemic), and similar events. In addition, because we lease off-site data center facilities, we cannot be assured that we will be able to expand our data center infrastructure to meet user demand in a timely manner, or on favorable economic terms. If we have issues receiving and processing data, this may delay our ability to provide products and services to our customers and business partners and damage our business. We also rely upon the performance of the systems and processes of our contract manufacturers to build and ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our products in a timely manner may be harmed. Since IT is critical to our operations, any failure to perform on the part of our IT providers could impair our ability to operate effectively. In addition to the risks outlined above, problems with any of the third parties we rely on for our IT systems could result in liabilities to our customers and business partners, lower revenue and unexecuted efficiencies, and impact our results of operations and our stock price.

55

Integration of acquisitions could disrupt our business and harm our financial condition and stock price and may dilute the ownership of our stockholders.

We have made, and may continue to make, acquisitions in order to enhance our business. For example, we acquired Mist Systems in 2019, HTBase in 2018 and Cyphort in 2017. Acquisitions involve numerous risks, including, but not limited to, problems combining the purchased operations, technologies or products, unanticipated costs, liabilities, litigation, and diversion of management's attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and where competitors in such markets have stronger market positions, initial dependence on unfamiliar supply chains or relatively small supply partners, failure of our due diligence processes to identify significant problems, liabilities or other challenges of an acquired company or technology, and the potential loss of key employees, customers, distributors, vendors, and other business partners of the companies we acquire.

There can be no assurance that we will be able to successfully integrate any businesses, products, technologies, or personnel that we might acquire or that the transaction will advance our business strategy. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions. If we fail to successfully manage, operate, or integrate any acquired business or if we are unable to efficiently operate as a combined organization, including through the use of common information and communication systems, operating procedures, financial controls, and human resources practices, we could be required to write-down investments and our business, financial condition, and results of operations may be adversely affected.

In connection with certain acquisitions, we may agree to issue common stock, or assume equity awards, that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities (both known and unknown), record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write-offs and restructuring and other related expenses, all of which could harm our financial condition and results of operations.

We are a party to lawsuits, investigations, proceedings, and other disputes, which are costly to defend and, if determined adversely to us, could require us to pay fines or damages, undertake remedial measures or prevent us from taking certain actions, any or all of which could harm our business, results of operations, financial condition or cash flows.

We, and certain of our current and former officers and current and former members of our Board of Directors, have been and may become subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement, as well as securities laws. In addition, certain U.S. governmental agencies previously conducted investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act, or the FCPA, which ultimately resulted in the Company entering into a settlement with the SEC that involved the Company making a payment of $11.8 million in August 2019.

Generally, we cannot predict the duration, scope, outcome, or consequences of litigation and government investigations. In connection with any limitation or government investigations, we may agree to settle the matter, we may be required to pay damages and incur other remedies, which may be material, and we may suffer reputational harm. In addition, if we fail to comply with the terms of any settlement agreement, we could face more substantial penalties. The lawsuits and investigations are expensive and time-consuming to defend, settle, and/or resolve, and may require us to implement certain remedial measures that could prove costly or disruptive to our business and operations. The unfavorable resolution of one or more of these matters could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We are a party to litigation and claims regarding intellectual property rights, resolution of which may be time-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers, suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. In addition, increased patent litigation brought by non-practicing entities in recent years may result, and in some cases has resulted, in our customers requesting or requiring us to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition, and results of operations. Regardless of the merit of these claims, they have been and can be time-consuming, result in costly litigation, and may require us to develop non-

56

infringing technologies, enter into license agreements, or cease engaging in certain activities or offering certain products or services. Furthermore, because of the potential for high awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may be settled for significant amounts of money. If any infringement or other intellectual property claim made against us or anyone we are required to indemnify by any third-party is successful, if we are required to settle litigation for significant amounts of money, if we fail to develop non-infringing technology, if we incorporate infringing technology in our products, or if we license required proprietary rights at material expense, our business, financial condition, and results of operations could be materially and adversely affected.

As we seek to sell more products directly to telecommunications, cable and cloud service provider companies and other large customers, we may be required to agree to non-standard terms and conditions that could have an adverse effect on our business or impact the amount of revenues to be recognized.

Telecommunications, cable and cloud service provider companies, which comprise a significant portion of our customer base, and other large companies, generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers. As we seek to sell more products directly to this class of customer, we may be required to agree to such terms and conditions, which may include terms that affect the timing of our ability to recognize revenue, increase our costs and have an adverse effect on our business, financial condition, and results of operations. Consolidation among such large customers can further increase their buying power and ability to require onerous terms.

In addition, these types of customers have purchased products from other vendors who promised but failed to deliver certain functionality and/or had products that caused problems or outages in the networks of these customers. As a result, these customers may request additional features from us and require substantial penalties for failure to deliver such features or may require substantial penalties for any network outages that may be caused by our products. These additional requests and penalties, if we are required to agree to them, may impact the amount of revenue recognition from such sales, which may negatively affect our business, financial condition and results of operations. In addition, increased patent litigation brought against customers in recent years, may result, and in some cases has resulted, in customers requesting or requiring vendors to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition, and results of operations.

Regulation of our industry in general and the telecommunications industry in particular could harm our operating results and future prospects.

We are subject to laws and regulations affecting the sale of our products in a number of areas. For example, some governments have regulations prohibiting government entities from purchasing security products that do not meet country-specific safety, conformance or security certification criteria or in-country test requirements. Other regulations that may negatively impact our business include local content or local manufacturing requirements most commonly applicable for government, state-owned enterprise or regulated industry procurements. These types of regulations are in effect or under consideration in several jurisdictions where we do business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act includes disclosure requirements applicable to public companies regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries, which we refer to collectively as the DRC, and procedures regarding a manufacturer's efforts to prevent the sourcing of such “conflict minerals.” These minerals are present in our products. In addition, the European Union, or EU, adopted an EU-wide conflict minerals rule in 2017 with compliance required by 2021 under which most EU importers of tin, tungsten, tantalum, gold, and their ores will have to conduct due diligence to ensure the minerals do not originate from conflict zones and do not fund armed conflicts. Large manufacturers also will have to disclose how they plan to monitor their sources to comply with the rules.

In addition, environmental laws and regulations relevant to electronic equipment manufacturing or operations, including laws and regulations governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment, may adversely impact our business and financial condition. These laws and regulations include, among others, the EU Restriction on the Use of Certain Hazardous Substances Directive, or RoHS. The EU RoHS and the similar laws of other jurisdictions limit the content of certain hazardous materials, such as lead, mercury, and cadmium, in electronic equipment, including our products. Currently, our products comply with the EU RoHS requirements. However, certain exemptions are scheduled to lapse. The lapse of any exemption, further changes to this or other laws, or passage of similar laws in the EU or other jurisdictions, would require us to cease selling non-compliant products and to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us, disrupt our operations or logistics, and result in an adverse impact on our operating results. In addition, in validating the compliance of our products with applicable hazardous materials restrictions, we rely substantially on affirmations by our component suppliers as to the compliance of their

57

products with respect to those same restrictions. Failure by our component suppliers to furnish accurate and timely information could subject us to penalties or liability for violation of such hazardous materials restrictions, interrupt our supply of products to the EU, and result in our customers refusing or being unable to purchase our products. Additionally, the EU and a number of other jurisdictions have adopted regulations requiring producers of electrical and electronic equipment to assume certain responsibilities for collecting, treating, recycling and disposing of products when they have reached the end of their useful life. Finally, the EU REACH regulations regulate the handling of certain chemical substances that may be used in our products.

In addition, as a contractor and subcontractor to U.S. government departments and agencies, we are subject to federal regulations pertaining to our IT systems. For instance, as a subcontractor to the U.S. Department of Defense, the Defense Federal Acquisition Regulation Supplement, or DFARS, required that our IT systems comply with the security and privacy controls described in National Institute of Standards and Technology Special Publication 800-171. The DFARS also requires that we flow the security control requirement down to certain of our own subcontractors. Failure to comply with these requirements could result in a loss of federal government business, subject us to claims or other remedies for non-compliance and negatively impact our business, financial condition, and results of operations.

The telecommunications industry is highly regulated, and our business and financial condition could be adversely affected by changes in regulations relating to the Internet telecommunications industry. Similarly, while there are currently few laws or regulations that apply directly to access to or commerce on IP networks, future regulations could include Internet service provider access charges. We could be adversely affected by regulation of IP networks and commerce in any country where we market equipment and services to service providers or cloud provider companies. Regulations governing the range of services and business models that can be offered by service providers or cloud provider companies could adversely affect those customers' needs for products. For instance, in December 2017, the U.S. Federal Communications Commission repealed its 2015 regulations governing aspects of fixed broadband networks and wireless networks. This change in regulatory treatment of networks might impact service provider and cloud provider business models and their need for Internet telecommunications equipment and services. At the same time, several states have enacted their own laws and regulations governing certain aspects of fixed and wireless networks in the manner of the 2015 FCC regulations. These laws and regulations enacted by the states are or will be subject to legal challenges from the federal government and/or regulated providers. Also, many jurisdictions are evaluating or implementing regulations relating to cyber security, supply chain integrity, privacy and data protection, any of which can affect the market and requirements for networking and security equipment.

The adoption and implementation of additional regulations could reduce demand for our products, increase the cost of building and selling our products, result in product inventory write-offs, impact our ability to ship products into affected areas and recognize revenue in a timely manner, require us to spend significant time and expense to comply, and subject us to fines and civil or criminal sanctions or claims if we were to violate or become liable under such regulations. Any of these impacts could have a material adverse effect on our business, financial condition, and results of operations.

Governmental regulations and economic sanctions affecting the import or export of products generally or affecting products containing encryption capabilities, in particular, could negatively affect our revenues and operating results.

The United States and various foreign governments have imposed controls and restrictions on the export of, among other things, certain telecommunications products and components, particularly those that contain or use encryption technology. Most of our products contain or use encryption technology and, consequently, are subject to such controls, requirements and restrictions. Certain governments, like those of Russia and China, control importation and in-country use of encryption items and technology. The scope, nature, and severity of such controls vary widely across different countries and may change frequently over time.

For several years, U.S. government officials have had concerns with the security of products and services from certain telecommunications and video providers based in China. As a result, Congress has enacted bans on the use of certain Chinese-origin components or systems either in items sold to the U.S. government or in the internal networks of government contractors and subcontractors (even if those networks are not used for government-related projects). The U.S. government might also restrict or ban the use of certain Chinese-origin components and systems in next generation mobile communications networks (e.g. 5G).

In November 2019, the U.S. Department of Commerce, or Commerce Department, proposed a rule that would subject to government review the acquisition or use of information and communication technology, goods and services from entities owned by, controlled by, or subject to the jurisdiction of a foreign adversary. The proposal would be retroactive and apply to transactions dating back to May 15, 2019. If implemented as proposed, the rule could subject acquisition of components, modules, other parts, and any services to lengthy government review processes. This would introduce significant uncertainty into our supply chain planning as we would not be certain which potential acquisitions the government would permit and which it would reject.

58

Increasingly, governments have begun using export and import controls not only to further national security objectives but also to protect local industries and restrict proliferation of locally developed “emerging or foundational technology." For example, in 2018 the U.S. enacted the Export Control Reform Act, which expands the power of the Commerce Department to use export controls to protect domestic industry and to restrict the export of emerging and foundational technologies not currently subject to controls. Our ability to market and sell our products overseas may be impacted by such export controls, if and when they are imposed.

In addition, the U.S. and other governments have especially broad sanctions and embargoes prohibiting provision of goods or services to certain countries, territories, and sanctioned governments, legal entities and individuals. Some of these restrictions have been imposed not just to protect national security but also to protect domestic industries and to achieve political aims. For instance, the Commerce Department in 2018 added to its Entity List, a Chinese semiconductor manufacturer on the express basis that it threatens the viability of U.S. competitors; the Entity List traditionally is used to restrict exports to end users that pose a security risk. Particularly far reaching and complex are restrictions imposed by the U.S. and EU on exports to Russia and, in particular, to the disputed region of Crimea. We have implemented systems to detect and prevent sales into these restricted countries or to prohibited entities or individuals, but there can be no assurance that our third party, downstream resellers and distributors will abide by these restrictions or have processes in place to ensure compliance, especially where local government regulation might prohibit adherence to such restrictions.

Certain governments also impose special local content, certification, testing, source code review, escrow and governmental recovery of private encryption keys, or other cybersecurity feature requirements to protect network equipment and software procured by or for the government. Similar requirements also may be imposed in procurements by state owned entities (“SOEs”) or even private companies forming part of “critical network infrastructure” or supporting sensitive industries. For example, China, Vietnam and India have promulgated cybersecurity regulations affecting networking products that may impair our ability to profitably market and sell our products there. China, in particular, is expected to require implementation of non-standard Chinese encryption algorithms in products sold into certain government, SOE, critical infrastructure, and sensitive industry (such as financial institutions) markets.

In addition, governments sometimes impose additional taxes on certain imported products. For example, the United States and Chinese governments each have imposed tariffs on certain products originating from the other country. In 2018, the United States imposed tariffs on a large variety of products of China origin, and beginning on September 24, 2018, a large portion of Juniper products manufactured in China became subject to a 10% tariff on importation into the U.S. pursuant to the U.S. government’s List 3 tariff proceeding, which increased to 25% on May 10, 2019. In August 2019, the U.S. President announced that he would impose a 15% tariff on all remaining Chinese imports (List 4 imports) effective September 1, 2019 and several of our products became subject to such tariff. Pursuant to a U.S.-China trade deal signed in mid-January 2020, the List 3 rate will remain at 25% and the List 4 rate decreased to 7.5% on February 14, 2020.

Depending upon their duration and implementation, as well as our ability to mitigate their impact, these tariffs could materially affect our business, including in the form of increased cost of goods sold, increased pricing for customers, and reduced sales.

Governmental regulation of encryption or IP networking technology and regulation of imports or exports, or our failure to obtain required import or export approval for our products, or related economic sanctions could harm our international and domestic sales and adversely affect our revenues and operating results. In addition, failure to comply with such regulations could result in harm to our reputation and ability to compete in international markets, penalties, costs, seizure of assets (including source code) and restrictions on import or export privileges or adversely affect sales to government agencies or government-funded projects.

Our actual or perceived failure to adequately protect personal data could adversely affect our business, financial condition, and results of operations.

A wide variety of provincial, state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. Further, our legal and regulatory obligations in foreign jurisdictions are subject to unexpected changes, including the potential for regulatory or other governmental entities to enact new or additional laws or regulations, to issues rulings that invalidate prior laws or regulations, or to increase penalties significantly. Compliance with these laws and regulations can be costly and can delay or impede the development and offering of new products and services.

For example, the General Data Protection Regulation, which became effective in May 2018, imposes more stringent data protection requirements, and provides for significantly greater penalties for noncompliance, than the EU laws that previously applied. Further,

59

in July 2020, the Court of Justice of the European Union released a decision in the Schrems II case (Data Protection Commission v. Facebook Ireland, Schrems), declaring the EU-US Privacy Shield invalid and calling into question data transfers carried out under the European Commission’s Standard Contractual Clauses. As a result of the decision, we may face additional scrutiny from EU regulators in relation to the transfer of personal data from the EU to the US. Noncompliance with the GDPR can trigger fines of up to the greater of €20 million or 4% of global annual revenues. Additionally, the California Consumer Privacy Act (“CCPA”), which became effective January 1, 2020 requires, among other things, covered companies to provide new disclosures to California consumers, and allow such consumers new abilities to opt-out of certain sales of personal information. On June 1, 2020, the California Attorney General’s office submitted the final set of CCPA proposed regulations to the California Office of Administrative Law. On July 1, 2020, the enforcement of the CCPA began.

Aspects of the CCPA and its interpretation and enforcement remain uncertain. The effects of the CCPA potentially are significant and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. As an example, the CCPA gives California residents expanded rights to access and require deletion of their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal information is used. The CCPA also provides for civil penalties for violations, as well as a private right of action for data breaches that may increase data breach litigation. We may also be subject to additional obligations relating to personal data by contract that industry standards apply to our practices. Further, other states have also expanded their data protection laws. Additionally, the Federal Trade Commission and many state attorneys general are interpreting federal and state consumer protection laws to impose standards for the online collection, use, dissemination, and security of data. In addition, we may be or become subject to data localization laws mandating that data collected in a foreign country be processed and stored within that country.

Our actual or perceived failure to comply with applicable laws and regulations or other obligations to which we may be subject relating to personal data, or to protect personal data from unauthorized access, use, or other processing, could result in enforcement actions and regulatory investigations against us, claims for damages by customers and other affected individuals, fines, damage to our reputation, and loss of goodwill, any of which could have a material adverse effect on our operations, financial performance, and business. Further, evolving and changing definitions of personal data and personal information, within the EU, the U.S., U.K., and elsewhere, including the classification of IP addresses, machine identification information, location data, and other information, may limit or inhibit our ability to operate or expand our business, including limiting business relationships and partnerships that may involve the sharing or uses of data, and may require significant costs, resources, and efforts in order to comply.

Our ability to develop, market, and sell products could be harmed if we are unable to retain or hire key personnel or if our existing personnel were harmed by COVID-19.

Our future success and ability to maintain a technology leadership position depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel as well as the health of our personnel during a pandemic, including the COVID-19 pandemic. The supply of highly qualified individuals with technological and creative skills, in particular, engineers in very specialized technical areas who have the expertise necessary to develop new products and develop enhancements for our current products, and provide reliable product maintenance, or sales people with specialized industry expertise, is limited and competition for such individuals is intense. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel, engineers and sales people, and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products. There can be no assurance that others will not develop technologies that are similar or superior to our technology, or that we will not lose the services of employees due to COVID-19.

A number of our team members are foreign nationals who rely on visas and entry permits in order to legally work in the United States and other countries. In recent years, the United States has increased the level of scrutiny in granting H-1B, L-1 and other business visas. Compliance with new and unexpected United States immigration and labor laws could require us to incur additional unexpected labor costs and expenses or could restrain our ability to retain skilled professionals. Additionally, pandemics, such as the COVID-19 pandemic, may interfere with our ability to hire or retain personnel. For example, in response to the COVID-19 pandemic, the United States has recently suspended entry of foreign nationals who have recently been in China, the UK, numerous countries within the European Union, as well as certain other countries, which could impact our ability to attract, develop, integrate and retain highly skilled employees with appropriate qualifications from other countries. In June 2020, the U.S. President suspended the issuance of new U.S. Permanent Residency or “Green Cards” and H-1B, L-1 and other business visas through December 31, 2020. Further, in July 2020, the U.S. President signed an executive order ending Hong Kong’s differential treatment compared to China. Individuals born in Hong Kong will now be charged to the Peoples Republic of China quota for Green Cards instead of to the worldwide quota, which will significantly increase wait times and backlogs for most employment-based category visas, which could impact our ability recruit employees from Hong Kong.

60

Any of these restrictions could have a material adverse effect on our business, results of operations and financial conditions.

Our financial condition and results of operations could suffer if there is an impairment of goodwill or purchased intangible assets.

As of June 30, 2020, our goodwill was $3,337.1 million, and our purchased intangible assets were $161.3 million. We are required to test intangible assets with indefinite lives, including goodwill, annually or more frequently if certain circumstances change that would more likely than not reduce the fair value of a reporting unit and intangible assets below their carrying values. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, or whenever events or changes in circumstances indicate that the carrying amount of an intangible asset might not be recoverable, a charge to operations is recorded. Either event would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred. We have in the past recorded goodwill impairment charges. Declines in our level of revenues or declines in our operating margins, or sustained declines in our stock price, increase the risk that goodwill and intangible assets with indefinite lives may become impaired in future periods.

Our goodwill impairment analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows, the degree of volatility in equity and debt markets, and our stock price. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any impairment of goodwill or other intangible assets. However, any such impairment would have an adverse effect on our results of operations.

Changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our results.

Our future effective tax rates could be subject to volatility or adversely affected by the following: earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates; changes in the valuation of our deferred tax assets and liabilities; expiration of, or lapses in, the R&D tax credit laws applicable to us; transfer pricing adjustments related to certain acquisitions, including the license of acquired intangibles under our intercompany R&D cost sharing arrangement; costs related to intercompany restructuring; tax effects of share-based compensation; challenges to our methodologies for valuing developed technology or intercompany arrangements; limitations on the deductibility of net interest expense; or changes in tax laws, regulations, accounting principles, or interpretations thereof. For example, on November 12, 2019, in Altera Corp. v. Commissioner, the Ninth Circuit Court of Appeals denied Altera Corporation’s petition for rehearing en banc of its case, following the Ninth Circuit’s decision against Altera issued on June 7, 2019 (the “2019 Opinion”). The 2019 Opinion required related parties in an intercompany cost-sharing arrangement to share expenses related to share-based compensation. Altera appealed this decision to the U.S. Supreme Court, which on June 22, 2020, declined to review the decision. Following the U.S. Supreme Court’s decision, we expect our effective tax rate and current income tax payable to be higher. For example, in the second quarter of 2020, we recorded a discrete GAAP-only tax expense of approximately $18.2 million to reflect the cumulative tax impact of an increase in U.S. taxable income related to R&D costs with an offshore cost-sharing participant, which were not previously shared. In addition, the Tax Act made significant changes to the taxation of U.S. business entities that may have a meaningful impact to our provision for income taxes. These changes included a reduction to the federal corporate income tax rate, the current taxation of certain foreign earnings, the imposition of base-erosion prevention measures which may limit the deduction of certain transfer pricing payments, and possible limitations on the deductibility of net interest expense or corporate debt obligations. Accounting for the income tax effects of the Tax Act required significant judgments and estimates that are based on current interpretations of the Tax Act. The U.S. Department of the Treasury continues to issue regulations that affect various components of the Act. Our future effective tax rate may be impacted by changes in interpretation of the regulations, as well as additional legislation and guidance regarding the Act.

Furthermore, on October 5, 2015, the Organisation for Economic Co-operation and Development, an international association of 35 countries including the U.S., published final proposals under its Base Erosion and Profit Shifting, or BEPS, Action Plan. The BEPS Action Plan includes fifteen Actions to address BEPS in a comprehensive manner and represents a significant change to the international corporate tax landscape. These proposals, as adopted by countries, may increase tax uncertainty and adversely affect our provision for income taxes. In addition, we are generally subject to the continuous examination of our income tax returns by the Internal Revenue Service, and other tax authorities. It is possible that tax authorities may disagree with certain positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial position and operating results. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes, but the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are transactions where the ultimate tax determination is uncertain. Although we

61

believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our consolidated financial statements and may materially affect our financial results in the period or periods for which such determination is made. There can be no assurance that the outcomes from continuous examinations will not have an adverse effect on our business, financial condition, and results of operations.

We may face difficulties enforcing our proprietary rights, which could adversely affect our ability to compete.

We generally rely on a combination of patents, copyrights, trademarks, and trade secret laws and contractual restrictions on disclosure of confidential and proprietary information, to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently pending, there can be no assurance that any of our patent applications will result in issued patents or that any of our patents or other proprietary rights will not be challenged, invalidated, infringed or circumvented or that our rights will, in fact, provide competitive advantages to us or protect our technology, any of which could result in costly product redesign efforts, discontinuance of certain product offerings and other competitive harm.

In addition, despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors, and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that we have entered into such agreements with all parties who may have or have had access to our confidential information or that the agreements we have entered into will not be breached. We cannot guarantee that any of the measures we have taken will prevent misappropriation of our technology.

Furthermore, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled our success.

We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.

We derive a substantial portion of our revenues from our international operations, and we plan to continue expanding our business in international markets. We conduct significant sales and customer support operations directly and indirectly through our distributors and value-added resellers in countries throughout the world and depend on the operations of our contract manufacturers and suppliers that are located outside of the United States. In addition, a portion of our R&D and our general and administrative operations are conducted outside the United States. In some countries, we may experience reduced intellectual property protection.

As a result of our international operations, we are affected by economic, business regulatory, social, and political conditions in foreign countries, including the following:

• changes in general IT spending;

• the impact of the recent COVID-19 pandemic, and any other adverse public health developments, epidemic disease or other pandemic in the countries in which we operate or our customers are located, including regional quarantines restricting the movement of people or goods, reductions in labor supply or staffing, the closure of manufacturing facilities to protect employees, disruptions to global supply chains and suppliers ability to deliver materials on a timely or cost-effective basis, the resulting overall significant volatility and disruption of financial markets, and economic instability affecting customer spending patterns;

• the imposition of government controls, inclusive of critical infrastructure protection;

• changes in trade controls, economic sanctions, or other international trade regulations, which may affect our ability to import or export our products to or from various countries;

• laws that restrict sales of products that are developed, manufactured, or incorporate components or assemblies from certain countries to specific customers (e.g., U.S. federal government departments and agencies) and industry segments, or for particular uses or more generally;

62

• varying and potentially conflicting laws and regulations;

• political uncertainty, including demonstrations, that could have an impact on product delivery from and into the China region;

• fluctuations in local economies;

• wage inflation or a tightening of the labor market;

• executive orders and changes in law and interpretation of laws;

• tax policies that could have a business impact;

• import tariffs imposed by the United States and reciprocal tariffs imposed by foreign countries;

• data privacy rules and other regulations that affect cross border data flow; and

• the impact of the following on customer spending patterns: political considerations, unfavorable changes in tax treaties or laws, natural disasters, labor unrest, labor shortages or stoppages, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations.

Any or all of these factors has or could have an adverse impact on our business, financial condition, and results of operations.

In addition, the U.K.'s formal exit from the EU on January 31, 2020, commonly referred to as Brexit, has caused, and may continue to cause, uncertainty in the global markets. The U.K. is expected to enter a transition period until December 31, 2020 permitting negotiation of a free trade deal between the US and U.K. The consequences for the economies of the U.K. and EU member states as a result of the U.K.'s withdrawal from the EU remain unknown and unpredictable. Any impact from Brexit on the Company will depend, in part, on the outcome of tariff, trade and other negotiations. For example, changes to the way service providers conduct business and transmit data between the U.K. and the EU could require us to make changes to the way we handle customer data. We are also reviewing the impact of any resulting changes to EU or U.K. law that could affect our operations, such as labor policies, financial planning, product manufacturing, and product distribution. Political and regulatory responses to the withdrawal are still developing and we are in the process of assessing the impact the withdrawal may have on our business as more information becomes available, including, but not limited to changes to U.K. immigration policy that may affect our ability to attract and retain talent in EMEA. Nevertheless, because we conduct business in the EU and the U.K., any of the effects of Brexit, including those we cannot anticipate, could have a material adverse effect on our business, business opportunities, operating results, financial condition and cash flows. The lack of certainty given the pending EU-U.K. negotiations creates the risk that, notwithstanding that we have devoted significant resources to preparing for the impact of Brexit, we may not be adequately prepared for an unforeseen outcome.

Our business is also impacted by the negotiation and implementation of free trade agreements between the United States and other nations. Such agreements can reduce barriers to international trade and thus the cost of conducting business overseas. For instance, the United States reached a new trilateral trade agreement with the Governments of Canada and Mexico to replace the North American Free Trade Agreement (NAFTA). All the three nations have ratified the agreement, but must meet certain obligations before the agreement takes effect.

Many of the products that we have manufactured in China are transported by air cargo from Hong Kong. Hong Kong has experienced political demonstrations that previously resulted in cancellations or delays in flights in and out of China. Such demonstrations could result in us experiencing delays in product deliveries from China or require us to change our shipping practices, which could adversely impact our business. Further, in July 2020, the U.S. President signed into law an executive order that ends Hong Kong’s differential treatment compared to the Peoples Republic of China. We are still evaluating the impact of the executive order on our Hong Kong operations, which serves as a logistics hub for many of our APAC operations. While the executive order is not expected to result in any of our existing products being subject to additional tariffs as none of our products are currently manufactured in Hong Kong, it could impact the ability of our employees in Hong Kong as well as in our other APAC offices to access our networks.

Also, the spread of COVID-19 has and is likely to continue to affect the manufacturing and shipment of goods globally. For example, we continued to experience supply constraints during the second quarter of fiscal 2020 due to the effects of the COVID-19 pandemic. We experienced supply constraints due to both constrained manufacturing capacity, particularly in China and Malaysia,

63

as well as component parts shortages as our component vendors were also facing manufacturing challenges. These challenges resulted in extended lead-times to our customers and had a negative impact on our ability to recognize additional revenue in the second quarter. By way of further example, while the Chinese government has lifted certain restrictions on movement of people and goods to limit the spread of COVID-19, it is continuing to take control measures and recently imposed certain restrictions to limit the spread of COVID-19 in Beijing. Further, most other countries have imposed or are imposing certain restrictions on the movement of people and goods and may continue to lift and reimpose such restrictions as needed. Any delay in production or delivery of our products or components made by our suppliers due to an extended closure of our supplier's plants as a result of efforts to limit the spread of COVID-19 in China, India, Malaysia, and Mexico, or other countries where our suppliers operate could adversely impact our business. In addition, many airlines have canceled flights to and from China, affecting the ability to obtain components needed for manufacturing elsewhere. Worldwide travel restrictions have been imposed by many countries, including air travel and transport, that have caused and are likely to continue to cause delays in shipment of our products as well as increased logistics costs and will restrict our ability to attract, develop, integrate and retain highly skilled employees with appropriate qualifications from other countries.

Moreover, local laws and customs in many countries differ significantly from or conflict with those in the United States or in other countries in which we operate. In many foreign countries, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. There can be no assurance that our employees, contractors, channel partners, and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations. In addition, any theft or unauthorized use or publication of our intellectual property and other confidential business information could harm our competitive position.

Our products are highly technical and if they contain undetected defects, errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to additional costs or lawsuits or be required to pay damages in connection with any alleged or actual failure of our products and services.

Our products are highly technical and complex, are critical to the operation of many networks, and, in the case of our security products, provide and monitor network security and may protect valuable information. Our products have contained and may contain one or more undetected errors, defects, malware, or security vulnerabilities. These errors may arise from hardware or software we produce or procure from third parties. Some errors in our products may only be discovered after a product has been installed and used by end-customers.

Any errors, defects, malware, or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, negative publicity, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. In addition, in the event an error, defect, malware, or vulnerability is attributable to a component supplied by a third-party vendor, we may not be able to recover from the vendor all of the costs of remediation that we may incur. In addition, we could face claims for product liability, tort, or breach of warranty or indemnification. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. If our business liability insurance coverage is inadequate, or future coverage is unavailable on acceptable terms or at all, our financial condition and results of operations could be harmed. Moreover, if our products fail to satisfy our customers' quality expectations for whatever reason, the perception of and the demand for our products could be adversely affected.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Because a substantial portion of our business is conducted outside the United States, we face exposure to adverse movements in non-U.S. currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on our financial condition and results of operations.

The majority of our revenues and expenses are transacted in U.S. Dollars. We also have some transactions that are denominated in foreign currencies, primarily the British Pound, Chinese Yuan, Euro, and Indian Rupee related to our sales and service operations outside of the United States. An increase in the value of the U.S. Dollar could increase the real cost to our customers of our products in those markets outside the United States in which we sell in U.S. Dollars. This could negatively affect our ability to meet our customers' pricing expectations in those markets and may result in erosion of gross margin and market share. A weakened U.S.

64

Dollar could increase the cost of local operating expenses and procurement of raw materials to the extent we must purchase components in foreign currencies.

Currently, we hedge currency exposures associated with certain assets and liabilities denominated in nonfunctional currencies and periodically hedge anticipated foreign currency cash flows, with the aim of offsetting the impact of currency fluctuations on these exposures. However, hedge activities can be costly, and hedging cannot fully offset all risks, including long-term declines or appreciation in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines or appreciation in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.

If we fail to adequately evolve our financial and managerial control and reporting systems and processes, our ability to manage and grow our business will be negatively affected.

Our ability to successfully offer our products and implement our business plan in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business and business models in response to fluctuating market opportunities and conditions. We will need to continue to improve our financial and managerial control and our reporting systems and procedures in order to manage our business effectively in the future. If we fail to effectively improve our systems and processes or we fail to monitor and ensure that these systems and processes are being used correctly, our ability to manage our business, financial condition, and results of operations may be negatively affected.

If our products do not interoperate with our customers’ networks, installations will be delayed or cancelled and could harm our business.

Our products are designed to interface with our customers’ existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. Many of our customers’ networks contain multiple generations of products that have been added over time as these networks have grown and evolved. Our products must interoperate with many or all of the products within these networks as well as future products in order to meet our customers’ requirements. If we find errors in the existing software or defects in the hardware used in our customers’ networks, we may need to modify our software or hardware to fix or overcome these errors so that our products will interoperate and scale with the existing software and hardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our products do not interoperate with those of our customers’ networks, demand for our products could be adversely affected or orders for our products could be cancelled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.

Our products incorporate and rely upon licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be required to renegotiate our current third-party licenses or license additional technology from third-parties to develop new products or product enhancements or to facilitate new business models. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Some of our agreements with our licensors may be terminated for convenience by them. In addition, we cannot be certain that our licensors are not infringing the intellectual property rights of third parties or that our licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. Third- party technology we incorporate into our products that is deemed to infringe on the intellectual property of others may result, and in some cases has resulted, in limitations on our ability to source technology from those third parties, restrictions on our ability to sell products that incorporate the infringing technology, increased exposure to liability that we will be held responsible for incorporating the infringing technology in our products and increased costs involved in removing that technology from our products or developing substitute technology. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.

We rely on the availability and performance of information technology services provided by third parties, including IBM, which manages a significant portion of our systems.

Under the terms of our Master Services Agreement and certain Statements of Work, IBM provides us with a broad range of information technology services, such as applications, including support, development and maintenance; infrastructure

65

management and support, including for servers storage and network devices; and end user support including service desk. Our businesses are dependent on the services provided and systems operated for us by IBM and its third-party providers. The failure of one or more of these entities to meet our performance standards and expectations, including with respect to data security, may have a material adverse effect on our business, results of operations or financial condition.

Our success is dependent on our ability to maintain effective relationships with IBM and other third-party technology and service providers as well as the ability of IBM and any other third-party providers to perform as expected. We may terminate our agreement with IBM and any and all Statements of Work at any time on short notice for cause, convenience, certain specific performance failures, a breach of warranties by IBM, failure to transform, changes in law, force majeure, or a change in the control of either IBM or us. Depending on the type and timing of a termination, we may be required to pay certain termination amounts to IBM. IBM's only right to terminate the Master Services Agreement is based on our failure to comply with certain terms applying to disputed payments.

This arrangement is subject to various risks, some of which are not within our control. These risks include, but are not limited to, disruption in services and the failure to protect the security and integrity of our data under the terms of the agreement. We are unable to provide assurances that some or all of these risks will not occur. Failure to effectively mitigate these risks, if they occur, could have a material adverse effect on our operations and financial results. In addition, we could face significant additional costs or business disruption if our arrangement with IBM is terminated or impaired and we cannot find alternative IT services or support on commercially reasonable terms or on a timely basis or if we are unable to hire new employees in order to return these services in-house.

We are required to evaluate the effectiveness of our internal control over financial reporting and publicly disclose material weaknesses in our controls. Any adverse results from such evaluation may adversely affect investor perception, and our stock price.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filing if such controls were unable to provide assurance that a material error would be prevented or detected in a timely manner. We have an ongoing program to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controls design and test the system and process controls necessary to comply with these requirements. If in the future, our internal controls over financial reporting are determined to be not effective resulting in a material weakness or significant deficiency, investor perceptions regarding the reliability of our financial statements may be adversely affected which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

Failure to maintain our credit ratings could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.

The major credit rating agencies routinely evaluate our indebtedness. This evaluation is based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. There can be no assurance that we will be able to maintain our credit ratings and failure to do so could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.

We may be unable to generate sufficient cash flow to satisfy our expenses, make anticipated capital expenditures or service our debt obligations, including the Notes and the Revolving Credit Facility.

As of June 30, 2020, we had $1,700.0 million in aggregate principal amount of senior notes, which we refer to collectively as the Notes. In April 2019, we entered into a new credit agreement with certain institutional lenders that provides for a five-year $500.0 million unsecured revolving credit facility, which we refer to as the Revolving Credit Facility, with an option to increase the Revolving Credit Facility by up to an additional $200.0 million, subject to the lenders' approval. The credit agreement will terminate in April 2024, at which point all amounts borrowed must be repaid (subject to a one-year maturity extension option). As of June 30, 2020, no amounts were outstanding under the Revolving Credit Facility.

We may not be able to generate sufficient cash flow to enable us to satisfy our expenses, make anticipated capital expenditures or service our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). Our ability to pay our expenses, satisfy our debt obligations, refinance our debt obligations and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for at least the next twelve months to meet our anticipated requirements for working capital, capital expenditures and scheduled

66

payments of principal and interest on our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the Notes) or obtain additional financing. There is no assurance that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, or at all.

The indenture that governs the Notes contain various covenants that limit our ability and the ability of our subsidiaries to, among other things:

• incur liens;

• incur sale and leaseback transactions; and

• consolidate or merge with or into, or sell substantially all of our assets to, another person.

The Credit Agreement contains two financial covenants along with customary affirmative and negative covenants that include the following:

• maintenance of a leverage ratio no greater than 3.0x (provided that if a material acquisition has been consummated,

we are permitted to maintain a leverage ratio no greater than 3.5x for up to four quarters) and an interest coverage ratio no less than 3.0x

• covenants that limit or restrict the ability of the Company and its subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type.

As a result of these covenants, we are limited in the manner in which we can conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our ability to successfully operate our business. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of the indebtedness, which could result in an event of default under our other debt instruments. Our future operating results may not be sufficient to enable compliance with these covenants to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments, including those under the Notes, and the Revolving Credit Facility (if drawn upon).

In addition, under applicable U.S. tax laws and regulations, there are limitations on the deductibility of net business interest expenses. As a result, if our taxable income were to decline, we may not be able to fully deduct our net interest expense, which could have a material impact on our business.

Our failure to pay quarterly dividends to our stockholders or the failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.

Our ability to pay quarterly dividends or achieve our intended capital return policy will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital and debt service requirements, use of cash for acquisitions and other factors. Any failure to pay or increase future dividends as announced, or a reduction or discontinuation of quarterly dividends could have a material adverse effect on our stock price.

In January 2018, our Board of Directors approved a new $2.0 billion share purchase program, which replaced our prior authorization and in October 2019, the Board authorized the repurchase of up to an additional $1.0 billion of common stock under the 2018 Stock Repurchase Program. Any failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.

The investment of our cash balance and our investments in government and corporate debt securities and equity securities are subject to risks, which may cause losses and affect the liquidity of these investments.

On June 30, 2020, we had $1,460.3 million in cash and cash equivalents and $1,110.0 million in short-and long-term investments. We have invested these amounts primarily in asset-backed securities, certificates of deposit, commercial paper, corporate debt securities, foreign government debt securities, money market funds, mutual funds, time deposits, U.S. government agency securities,

67

and U.S. government securities. We also have $191.5 million in other long-term assets for our investments in privately-held companies. Certain of our investments are subject to general credit, liquidity, market, sovereign debt, and interest rate risks. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value related to creditworthiness of our publicly traded debt investments is judged to be material. In addition, should financial market conditions worsen in the future, including from the impact of the COVID-19 pandemic, investments in some financial instruments may be subject to risks arising from market liquidity and credit concerns. These market risks associated with our investment portfolio may have a material adverse effect on our liquidity, financial condition, and results of operations.

Changes in the method of determining the London Interbank Offered Rate, or LIBOR, or the replacement of LIBOR with an alternative reference rate, may adversely affect our financial condition and results of operations.

Certain of our financial obligations and instruments, including our credit facility, accounts receivable finance programs, and floating rate notes that we have invested in, as well as interest rate derivatives that we use as fair value and cash flow hedges , are or may be made at variable interest rates that use LIBOR (or metrics derived from or related to LIBOR) as a benchmark for establishing the interest rate. On July 27, 2017, the United Kingdom’s Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. These reforms may cause LIBOR to perform differently than in the past or to disappear entirely. There is currently no global consensus on what rate or rates will become acceptable alternatives. In the United States, the U.S. Federal Reserve Board-led industry group, the Alternative Reference Rates Committee, selected the Secured Overnight Financing Rate ("SOFR") as an alternative to LIBOR for U.S. dollar-denominated LIBOR-benchmarked obligations. SOFR is a broad measure of the cost of borrowing cash in the overnight U.S treasury repo market, and the Federal Reserve Bank of New York has published the daily rate since 2018. Nevertheless, because SOFR is a fully secured overnight rate and LIBOR is a forward-looking unsecured rate, SOFR is likely to be lower than LIBOR on most dates, and any spread adjustment applied by market participants to alleviate any mismatch during a transition period will be subject to methodology that remains undefined. The potential consequences of these actions cannot be fully predicted and could have an adverse impact on the market value for or value of LIBOR-linked securities, loans, and other financial obligations or extensions of credit held by or due to us. Changes in market interest rates may influence our financing costs, returns on financial investments and the valuation of derivative contracts and could reduce our earnings and cash flows. In addition, any transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that rely on LIBOR, reductions in the value of certain instruments or the effectiveness of related transactions such as hedges, increased borrowing costs, uncertainty under applicable documentation, or difficult and costly consent processes. This could materially and adversely affect our results of operations, cash flows, and liquidity.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the U.S. District Court for the District of Delaware) is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of fiduciary duty owed by any of our current or former directors, officers, or other employees to us or to our stockholders; (iii) any action asserting a claim arising pursuant to the Delaware General Corporation Law, our restated certificate of incorporation, or our bylaws; (iv) any action or proceeding asserting a claim as to which Delaware General Corporation Law confers jurisdiction on the Court of Chancery or (v) any action asserting a claim governed by the internal affairs doctrine. The exclusive forum provisions in our bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our current or former directors, officers, or other employees, which may discourage such lawsuits against us and our current or former directors, officers, and other employees. Alternatively, if a court were to find the exclusive forum provisions contained in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material and adverse impact on our business.

Uninsured losses could harm our operating results.

We self-insure against many business risks and expenses, such as intellectual property litigation and our medical benefit programs, where we believe we can adequately self-insure against the anticipated exposure and risk or where insurance is either not deemed cost-effective or is not available. We also maintain a program of insurance coverage for various types of liabilities, including, property, casualty, financial, business interruption, and other risks. We place our insurance coverage with various carriers in numerous jurisdictions. The types and amounts of insurance that we obtain vary from time to time and from location to location, depending on availability, cost, and our decisions with respect to risk retention. The policies are subject to deductibles, policy limits, and exclusions that result in our retention of a level of risk on a self-insurance basis. In addition, our insurance coverage

68

may not be adequate to compensate us for all losses or failures that may occur. Losses not covered by insurance could be substantial and unpredictable and could adversely affect our financial condition and results of operations.

Our stock price may fluctuate.

Historically, our common stock has experienced substantial price volatility, particularly as a result of variations between our actual financial results and the published expectations of analysts and as a result of announcements by our competitors and us. Furthermore, speculation in the press or investment community about our strategic position, financial condition, results of operations, business, security of our products, liabilities or significant transactions can cause changes in our stock price. In addition, the stock market has recently experienced extreme price and volume fluctuations that have affected the market price of many technology companies in particular due to the COVID-19 pandemic. From time to time, economic weakness has contributed to extreme price and volume fluctuations in global stock markets that have also reduced the market price of many technology company stocks, including ours. These factors, as well as general economic and political conditions and the announcement of proposed and completed acquisitions or other significant transactions, or any difficulties associated with such transactions, by us or our current or potential competitors, may materially adversely affect the market price of our common stock in the future.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

During the three months ended June 30, 2020, there were no share repurchases under our Board approved 2018 Stock Repurchase Program, which authorized us to purchase an aggregate of up to $3.0 billion of our common stock. Future share repurchases will be subject to a review of the circumstances in place at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements, including Rule 10b-18 promulgated under the Exchange Act. This program may be discontinued at any time. As of June 30, 2020, there was approximately $1.5 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

EXHIBIT 10.1

JUNIPER NETWORKS, INC.

2008 EMPLOYEE STOCK PURCHASE PLAN

As amended and restated as of May 14, 2020

1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Subsidiaries with an opportunity to purchase Common Stock through accumulated payroll deductions. The Company’s intention is to have the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code, although the Company makes no undertaking nor representation to maintain such qualification. The provisions of the Section 423(b) Plan (as defined below), accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, this Plan document authorizes the grant of rights to purchase stock that do not qualify under Section 423(b) of the Code (“Non-Section 423(b) Plan”) pursuant to rules, procedures, appendices or sub-plans adopted by the Board or Committee designed to achieve tax, securities law or other Company compliance objectives for Eligible Employees (as defined below) of Designated Non-423 Subsidiaries (as defined below) in particular locations outside the United States. Such references to the Plan include the Section 423(b) and the Non-Section 423(b) Plan components.

(ii) The consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; or

(iii) The consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or

(iv)  A change in the composition of the Board occurring within a two (2) year period, as a result of which less than a majority of the Directors are Incumbent Directors. “Incumbent Directors” means Directors who either (A) are Directors as of the effective date of the Plan, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of the Directors at the time of such election or nomination (but will not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of Directors to the Company).

(bb) “Trading Day” means a day on which the stock exchange or national market system on which shares of Common Stock are listed is open for trading.

3. Eligibility.

(a) Offering Periods. Any individual who is an Eligible Employee on a given Offering Date will be eligible to participate in such Offering Period, subject to the requirements of Section 5.

(b) Limitations. Any provisions of the Plan to the contrary notwithstanding, no Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate which exceeds twenty-five thousand dollars ($25,000) worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time.

4. Offering Periods and Purchase Periods. The Plan will be implemented by consecutive Offering Periods with a new Offering Period commencing on the first Trading Day on or after February 1 and August 1 each year, or on such other date as the Administrator will determine. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future offerings without stockholder approval if such change is announced to Eligible Employees at least five (5) days prior to the scheduled beginning of the first Offering Period to be affected thereafter. For purposes of the Plan, the Administrator may designate separate Offering Periods under the Plan in which Eligible Employees will participate and the provisions of the Plan will separately apply to each Offering Period.  For purposes of clarity, the terms of each Offering Period need not be identical provided that if the Offering Period is being implemented pursuant to the provisions of the Plan that are intended to qualify under Section 423(b) of the Code, the terms of the Plan and the Offering Period together must satisfy Section 423 of the Code.

Each Offering Period shall consist of four (4) consecutive periods (each, a “Purchase Period”) of approximately six (6) months duration, or such other number or duration as the Administrator shall determine. A Purchase Period commencing (i) on the first Trading Day on or after February 1 shall terminate on the last Trading Day in the period ending on July 31 and (ii) on the first Trading Day on or after August 1 shall terminate on the last Trading Day in the period ending on January 31. Notwithstanding the foregoing, the Administrator may establish a different duration for one or more future Purchase Periods or different commencing or ending dates for such Purchase Periods.

5. Participation. An Eligible Employee may participate in the Plan pursuant to Section 3(a) by (i) submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Administrator prior to an applicable Offering Date, a properly completed subscription agreement authorizing payroll deductions in the form as specified by the Company for such purpose, or (ii) following an electronic or other enrollment procedure prescribed by the Company.

3

6. Payroll Deductions.

(a) At the time a participant enrolls in the Plan pursuant to Section 5, he or she will elect to have payroll deductions made on each pay day during the Offering Period for which the participant has enrolled in. Subject to Applicable Law, the payroll deduction amount for a participant shall not exceed ten percent (10%) of the Compensation which he or she receives on each pay day during the Offering Period. The Administrator, in its discretion, may decide that an Eligible Employee may submit contributions to the Non-Section 423(b) Plan by means other than payroll deductions. A participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Sections 10 and 11 hereof. An Eligible Employee that enrolls in the Plan after the Offering Date for an Offering Period shall not (i) be eligible to participate in such Offering Period but may participate in the subsequent Offering Period and (ii) have deductions withheld from such Eligible Employee’s payroll for purposes of participation in the Plan until after the commencement of such subsequent Offering Period.

(b) Payroll deductions for a participant will commence on the first pay day following the Offering Date and will end on the last pay day prior to the termination of such Offering Period to which such authorization is applicable, unless sooner terminated as provided in Sections 10 and 11 hereof.

(c) All payroll deductions made for a participant will be credited to his or her account under the Plan and will be withheld in whole percentages only. A participant may not make any additional payments into such account. No Eligible Employee shall be permitted to participate simultaneously in more than one Offering Period.

(d) Subject to Applicable Law, a participant may discontinue his or her participation in the Plan as provided in Section 10, or may decrease the rate of his or her payroll deductions during the Offering Period by (i) properly completing and submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Company prior to an applicable Exercise Date, a new subscription agreement authorizing the change in payroll deduction rate in the form provided by the Company for such purpose, or (ii) following an electronic or other procedure prescribed by the Company. If a participant has not followed such procedures to change the rate of payroll deductions, the rate of his or her payroll deductions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless terminated as provided in Section 6(d)). The Company may, in its sole discretion, limit the nature and/or number of payroll deduction rate changes that may be made by participants during any Offering Period. Any change in payroll deduction rate made pursuant to this Section 6(d) will be effective as of the first full payroll period following five (5) business days after the date on which the change is made by the participant. If a participant decreases his or her payroll deductions to zero percent (0%), any subsequent election to increase his or her rate of payroll deductions will not take effect until the next Purchase Period (or the next Offering Period, if such increase is being made in the last Purchase Period of the Offering Period). If a participant elects to increase his or her payroll deductions during a Purchase Period, such election will not take effect until the next Purchase Period (or the next Offering Period, if such increase is being made in the last Purchase Period of the Offering Period).

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) and Applicable Law, a participant’s payroll deductions may be decreased to zero percent (0%) at any time during an Offering Period. Subject to Section 423(b)(8) of the Code and Section 3(b) hereof, payroll deductions will recommence at the rate originally elected by the participant prior to such reduction, unless terminated by the participant as provided in Section 10.

(f) At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is disposed of, the participant must make adequate provision for the Company’s or Employer’s federal, state, or any other tax withholding liability payable to any authority, national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the Company or the Employer may, but will not be obligated to, withhold from the participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to the sale or early disposition of Common Stock by the participant.

7. Grant of Option. On the Offering Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible

4

Employee’s payroll deductions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to purchase during any twelve (12) month period more than six thousand (6,000) shares of the Common Stock (subject to any adjustment pursuant to Section 19), and provided further that such purchase will be subject to the limitations set forth in Sections 3(b) and 13. The Eligible Employee may accept the grant of such option with respect to any Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that each Eligible Employee may purchase during each Offering Period. Exercise of the option will occur as provided in Section 8, unless the participant has withdrawn pursuant to Sections 10 or 11. The option will expire on the last day of the Offering Period.

8. Exercise of Option.

(a) Unless a participant withdraws from the Plan as provided in Sections 10, 11 or otherwise, his or her option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares of Common Stock subject to his or her option will be purchased for such participant at the applicable Purchase Price with the accumulated payroll deductions remaining in his or her account that have not been previously applied toward the purchase of Common Stock under this Plan. No fractional shares of Common Stock will be purchased; any payroll deductions accumulated in a participant’s account which are not sufficient to purchase a full share of Common Stock will be retained in the participant’s account for the subsequent Offering Period or Purchase Period, as applicable, subject to earlier withdrawal by the participant as provided in Sections 10 and 11. Any other funds left over in a participant’s account after the Exercise Date will be returned to the participant. During a participant’s lifetime, a participant’s option to purchase shares hereunder is exercisable only by him or her. No shares of Common Stock shall be purchased on an Exercise Date on behalf of a participant whose participation in an Offering Period or the Plan has terminated before such Exercise Date.

(b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Exercise Date in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and the Administrator may continue all Offering Periods then in effect or terminate all Offering Periods then in effect pursuant to Section 20. The Company may make a pro rata allocation of the shares available on the Offering Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Offering Date.

9. Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each participant the shares purchased upon exercise of his or her option in a form determined by the Company (in its sole discretion), subject to any rules established by the Administrator. No participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the participant as provided in this Section 9.

10. Withdrawal.

(a) A participant may withdraw all but not less than all the payroll deductions credited to his or her account and not yet used to exercise his or her option under the Plan on or prior to such date or dates that have been designated by the Administrator from time to time in its sole discretion by (i) submitting to the Company’s payroll office (or its designee) a written notice of withdrawal in the form prescribed by the Company for such purpose, or (ii) following an electronic or other withdrawal procedure prescribed by the Company. All of the participant’s payroll deductions credited to his or her account will be paid to such participant promptly after receipt of notice of withdrawal and such participant’s option for the Offering Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made for such Offering Period. If a participant withdraws from an Offering Period, payroll deductions will not resume at the beginning of the succeeding Offering Period, unless the participant re-enrolls in the Plan in accordance with the provisions of Section 5.

5

(b) A participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods which commence after the termination of the Offering Period from which the participant withdraws.

(c) Automatic Rollover. If the Fair Market Value of a share of Common Stock on an Exercise Date (other than the final Exercise Date of an Offering Period) is less than the Fair Market Value of a share of Common Stock on the Offering Date of an Offering Period (each such Offering Period, a “Terminating Offering Period”), then (i) each Terminating Offering Period shall terminate immediately at the end of such Exercise Date, but, for the avoidance of doubt, after giving effect to the exercise and purchase of shares of Common Stock for the Purchase Period, and (ii) each participant in such Terminating Offering Period shall be automatically enrolled in the Offering Period commencing on the first Trading Day immediately following such Exercise Date.

11. Termination of Eligibility. Upon a participant’s ceasing to be an Eligible Employee, for any reason, he or she will be deemed to have elected to withdraw immediately from the Plan (and the participant’s participation in the Plan shall terminate immediately) and the payroll deductions credited to such participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such participant’s option will be automatically terminated. If a participant transfers employment from the Company or any Designated Subsidiary participating in the Section 423 Component to any Designated Subsidiary participating in the Non-Section 423 Component, such transfer shall not be treated as a termination of employment, but the participant shall immediately cease to participate in the Section 423 Component; however, any contributions made for the Offering Period in which such transfer occurs shall be transferred to the Non-Section 423 Component, and such participant shall immediately join the then-current Offering under the Non-Section 423 Component upon the same terms and conditions in effect for the participant’s participation in the Section 423 Component, except for such modifications otherwise applicable for participants in such Offering Period. A participant who transfers employment from any Designated Subsidiary participating in the Non-Section 423 Component to the Company or any Designated Subsidiary participating in the Section 423 Component shall not be treated as terminating the participant’s employment and shall remain a participant in the Non-Section 423 Component until the earlier of (i) the end of the current Offering Period under the Non-Section 423 Component, or (ii) the Offering Date of the first Offering Period in which the participant is eligible to participate following such transfer. Notwithstanding the foregoing, the Administrator may establish different rules to govern transfers of employment between companies participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable requirements of Section 423 of the Code.

12. Interest. No interest will accrue on the payroll deductions of a participant in the Plan, unless required by Applicable Laws.

13. Stock.

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of Common Stock which will be made available for sale under the Plan will be forty-three million (43,000,000) shares.

(b) Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

(c) Shares of Common Stock to be delivered to a participant under the Plan will be registered in the name of the participant or, at the sole discretion of the Company, in the name of the participant and his or her spouse.

14. Administration.

The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding, decision and determination made by the Administrator will, to the full extent

6

permitted by law, be final and binding upon all parties. Notwithstanding any provision to the contrary in this Plan, and, with respect to the Section 423(b) Plan, to the extent permissible under Code Section 423 and proposed or final Treasury Regulations promulgated thereunder (and other Internal Revenue Service guidance), the Administrator may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures for jurisdictions outside of the United States. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding handling payroll deductions, payment of interest, making of contributions to the Plan, defining eligible Compensation, establishment of bank or trust accounts to hold payroll deductions, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, data privacy security, withholding procedures and handling of stock certificates which vary with local requirements.

The Administrator may also adopt rules, procedures, appendices or sub-plans applicable to particular Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Code Section 423. The rules of such sub-plans may take precedence over other provisions of this Plan, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan. To the extent inconsistent with the requirements of Code Section 423, such sub-plan shall be considered part of the Non-Section 423(b) Plan, and rights granted thereunder shall not be considered to comply with Code Section 423.

15. Designation of Beneficiary.

(a) At the sole discretion of the Company and subject to Applicable Law, a participant may file a designation of a beneficiary who is to receive any shares of Common Stock and cash, if any, from the participant’s account under the Plan in the event of such participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such participant of such shares and cash. In addition, a participant may file a designation of a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to exercise of the option. If a participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

(b) Such designation of beneficiary may be changed by the participant at any time by notice in a form determined by the Company. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company will deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

(c) All beneficiary designations will be in such form and manner as the Company may designate from time to time.

16. Transferability. Neither payroll deductions credited to a participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

17. Use of Funds. The Company may use all payroll deductions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such payroll deductions. Until shares of Common Stock are issued, participants will only have the rights of an unsecured creditor with respect to such shares.

18. Reports. Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of payroll deductions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

19. Adjustments, Dissolution, Liquidation, Merger or Change in Control.

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities

7

of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock which may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised, and the numerical limits of Sections 7 and 13.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant’s option has been changed to the New Exercise Date and that the participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period.

(c) Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date and will end on the New Exercise Date. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant’s option has been changed to the New Exercise Date and that the participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period.

20. Amendment or Termination.

(a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason; provided, however, that adding additional shares available for sale under the Plan (other than pursuant to Section 19(a)) shall require stockholder approval. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If the Offering Periods are terminated prior to expiration, all payroll deduction amounts then credited to participants’ accounts which have not been used to purchase shares of Common Stock will be returned to the participants (without interest thereon, except as otherwise required under Applicable Laws) as soon as administratively practicable.

(b) Without stockholder consent and without limiting Section 20(a), to the extent permitted by applicable provisions of law, the Administrator will be entitled to amend the Offering Periods, determine the terms of new Offering Periods (including, but not limited to (i) the length of such Offering Periods, provided that no such Offering Period shall be more than 27 months, (ii) whether such Offering Periods will include one or more embedded Offering Periods and/or (iii) whether such Offering Periods will have an automatic restart or reset provision), provide for overlapping Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each participant properly correspond with amounts withheld from the participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan.

(c) In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:

8

(i) amending the Plan to conform with the safe harbor definition under Statement of Financial Accounting Standards 123(R), including with respect to an Offering Period underway at the time;

(ii) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price;

(iii) shortening any Offering Period by setting a New Exercise Date, including an Offering Period underway at the time of the Administrator action;

(iv) reducing the maximum percentage of Compensation a participant may elect to set aside as payroll deductions; and

(v) reducing the maximum number of shares a participant may purchase during any Offering Period.

Such modifications or amendments will not require stockholder approval or the consent of any Plan participants.

21. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

22. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

23. Term of Plan. The Plan will continue in effect until February 25, 2028, unless sooner terminated under Section 20.

24. Reimbursement of Taxes. The Administrator shall have the discretion to require reimbursement from any Plan participant in full for any liability that the Company or the Employer incurs towards any tax paid or payable in respect to participant’s participation in the Plan, the grant of any option pursuant to the Plan, or the exercise of participant’s option, provided that such reimbursement is provided for in the subscription agreement. The Company may require security for such reimbursement of taxes as a precondition to participant participating in the Plan, the grant of any option, or the exercise of this option on behalf of Participant. The Administrator shall have the authority to approve additional documents or forms which may be requested by the Company for such security, collection or otherwise for reimbursement of such taxes to the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Note 1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The Condensed Consolidated Financial Statements of Juniper Networks, Inc. (the “Company” or “Juniper”) were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2019 has been derived from the audited Consolidated Financial Statements at that date. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any future period.

These Condensed Consolidated Financial Statements and accompanying notes should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 (the "Form 10-K"). We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued.

The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Actual results could differ materially from those estimates under different assumptions or conditions.

Summary of Significant Accounting Policies

Except for the change in certain policies upon adoption of the accounting standards and the policy for interest rate lock cash flow hedges described below, there have been no significant changes to the Company's significant accounting policies described in Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

The Company records changes in fair value of interest rate locks in accumulated other comprehensive income (loss) in the consolidated balance sheets, in the period of change. When the forecasted transaction occurs, the Company will start to amortize the accumulated gain or losses included as a component of other comprehensive income (loss) related to the interest rate lock cash flow hedges to interest expense. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) will be reclassified to other income and expense within income statement.

Recently Adopted Accounting Standards

Fair Value Measurement: On January 1, 2020, the Company adopted ASU No. 2018-13 (Topic 820) Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds, and modifies certain disclosure requirements for fair value measurements under ASC 820. The Company adopted the standard under the prospective approach for certain modified or new disclosure requirements, and all other amendments in the standard under the retrospective approach. See Note 3, Fair Value Measurements for required disclosures.

Simplifying the Test for Goodwill Impairment: On January 1, 2020, the Company adopted ASU No. 2017-04 (Topic 350) Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. The Company adopted the standard under the prospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Credit Losses on Financial Instruments: On January 1, 2020, the Company adopted ASU 2016-13 (Topic 326) Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments, as further clarified by the Financial Accounting Standards Board (the "FASB") through the issuance of additional related ASUs, which requires the measurement and recognition of current expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model, which requires the use of forward-looking information to calculate credit loss

estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. The Company adopted the standard under the modified retrospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Recent Accounting Standards Not Yet Adopted

Reference Rate Reform: In March 2020, the FASB issued ASU No. 2020-04 (Topic 848), Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients and exceptions to the existing guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (SOFR). The standard was effective upon issuance and may generally be applied through December 31, 2022, to any new or amended contracts, hedging relationships, and other transactions that reference LIBOR. The Company is currently evaluating the impact of the transition and disclosure requirements of the standard on its Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes: In December 2019, the FASB issued ASU No. 2019-12 (Topic 740) Income Taxes — Simplifying the Accounting for Income Taxes, which enhances and simplifies various aspects related to accounting for income taxes. This ASU is to be applied on a prospective basis with the exception of certain amendments that are to be applied on either a retrospective or modified retrospective basis. The new standard is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.

For available-for-sale debt securities that have unrealized losses, the Company assesses impairment by evaluating various factors, including whether (i) it has the intention to sell any of these investments and (ii) whether it is more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company periodically assesses performance indicators of the investment by evaluating various factors such as (i) changes in the credit ratings and (ii) review of the issuer. As of June 30, 2020, the Company had 121 investments in unrealized loss positions. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. The Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no allowance for credit losses was required to be recognized during the three and six months ended June 30, 2020 and June 30, 2019.

During the three and six months ended June 30, 2020 and June 30, 2019, there were no material gross realized gains or losses from available-for-sale debt securities.

The Company's Level 2 available-for-sale debt securities are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's derivative instruments are classified as Level 2, as they are not actively traded and are valued using pricing models that use observable market inputs. During the three and six months ended June 30, 2020, the Company had no transfers into or out of Level 3 of the fair value hierarchy of its assets or liabilities measured at fair value.

The Company's privately-held debt and redeemable preferred stock securities are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value of its privately-held debt and redeemable preferred stock securities on a recurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent valuations at the time of financing activities and the investee's capital structure. During the three and six months ended June 30, 2020, there were no significant activities related to privately-held debt and redeemable preferred stock securities.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

The Company's investments in equity securities without readily determinable fair value are classified as Level 3 assets due to the lack of observable inputs to determine fair value. The Company estimates the fair value on a nonrecurring basis (i.e. when an observable transaction occurs) using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. As of June 30, 2020, there have been no material upward or downward adjustments for price changes to the equity securities without readily determinable fair value.

Certain of the Company's assets, including intangible assets and goodwill, are measured at fair value on a nonrecurring basis. There were no significant impairment charges recognized during the three and six months ended June 30, 2020.

As of June 30, 2020 and December 31, 2019, the Company had no liabilities required to be measured at fair value on a nonrecurring basis.

Assets and Liabilities Not Measured at Fair Value

The carrying amounts of the Company's accounts receivable, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. As of June 30, 2020 and December 31, 2019, the estimated fair value of the Company's total outstanding debt in the Condensed Consolidated Balance Sheets was $1,950.1 million and $1,852.1 million, respectively, based on observable market inputs (Level 2). The carrying value of the promissory note issued to the Company in connection with the previously completed sale of Junos Pulse, along with the accumulated interest paid in kind, of $87.4 million and $78.9 million approximates its fair value as of June 30, 2020 and December 31, 2019, respectively. Notes receivable are generally classified as Level 3 assets due to the lack of observable inputs to determine fair value. The carrying value of a contract manufacturer deposit of $62.3 million, reported within other long-term assets, in the Condensed Consolidated Balance Sheets approximates its fair value as of June 30, 2020. See Note 5, Other Financial Information, for further information on the contract manufacturer deposit.

Designated Derivatives

The Company uses foreign currency forward contracts to hedge the Company's planned cost of revenues and operating expenses denominated in foreign currencies. These derivatives are designated as cash flow hedges and typically have maturities of thirty-six months or less.

During the three months ended June 30, 2020, the Company entered into interest rate locks with large financial institutions, which fixed benchmark interest rates of future debt issuance for an aggregate notional amount of $550.0 million. The swaps are designated as cash flow hedges and are expected to terminate within 5 years and 3 months.

In 2019, the Company entered into interest rate swaps with an aggregate notional amount of $300.0 million designated as fair value hedges of our fixed-rate 2041 Notes. These swaps convert the fixed interest rates of the notes to floating interest rates based on the LIBOR. Most of the interest rate swaps will expire within ten years or less.

Effect of Derivative Instruments on the Consolidated Statements of Operations

For cash flow hedges, the Company recognized an unrealized gain of $17.9 million and an unrealized loss of $11.2 million in accumulated other comprehensive income for the effective portion of its derivative instruments for the three and six months ended June 30, 2020, respectively. The Company recognized an unrealized loss of $2.1 million and an unrealized gain of $1.3 million in accumulated other comprehensive income for the effective portion of its derivative instruments for the three and six months ended June 30, 2019, respectively.

For foreign currency forward contracts, the company reclassified a loss of $6.9 million and $8.3 million out of accumulated other comprehensive income to cost of revenues and operating expenses in the Condensed Consolidated Statements of Operations during the three and six months ended June 30, 2020, respectively, and a gain of $0.3 million and loss of $0.7 million for the comparable periods ended June 30, 2019, respectively. As of June 30, 2020, an estimated $7.9 million of unrealized net loss within accumulated other comprehensive loss is expected to be reclassified into earnings within the next twelve months.

Non-Designated Derivatives

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. These foreign exchange forward contracts typically have maturities of approximately one to four months. The outstanding non-designated derivative instruments are carried at fair value. Changes in the fair value of these derivatives, which were recorded in other expense, net within the Condensed Consolidated Statements of Operations, were not material during the three and six months ended June 30, 2020 and June 30, 2019.

Restructuring Charges

Note 6. Restructuring Charges

During the first quarter of 2020, the Company initiated a restructuring plan (the "2020 Restructuring Plan") designed to realign its workforce with the Company's sales strategy, enhance productivity and cost efficiencies, and enable reinvestment in certain key priority areas. During the second quarter of 2020, the Company amended the 2020 Restructuring Plan and undertook further actions that resulted in additional severance costs.

During the three months ended June 30, 2020, the Company recorded $4.8 million in severance costs related to workforce reductions. During the six months ended June 30, 2020, the Company recorded $8.9 million in severance and $5.3 million in impairment charges included in other exit related costs, which were reported as restructuring charges in the Condensed Consolidated Statements of Operations.

Restructuring liabilities are reported within other accrued liabilities in the Condensed Consolidated Balance Sheets. The following table provides a summary of changes in the restructuring liabilities for the Company's 2020 and prior year restructuring plan (in millions):

During the three and six months ended June 30, 2019, the $27.94 average price per share excludes the forward contract of $60.0 million under the ASR, which was initiated and settled during the second and the third quarter of 2019, respectively.

Cash Dividends on Shares of Common Stock

During the three and six months ended June 30, 2020, the Company declared a quarterly cash dividend of $0.20 per share of common stock on January 27, 2020 and April 28, 2020, respectively, which was paid on March 23, 2020 and June 22, 2020, respectively, to stockholders of record on March 2, 2020 and June 1, 2020. Any future dividends, and the establishment of record and payment dates, are subject to approval by the Board of Directors (the “Board”) of Juniper or an authorized committee thereof. See Note 14, Subsequent Events, for discussion of the Company's dividend declaration subsequent to June 30, 2020.

Stock Repurchase Activities

In January 2018, the Board approved a $2.0 billion share repurchase program ("2018 Stock Repurchase Program"), which replaced our prior authorization. In October 2019, the Board authorized a $1.0 billion increase to the 2018 Stock Repurchase Program for a total of $3.0 billion.

In October 2019, the Company entered into an ASR, to repurchase an aggregate of approximately $200.0 million of the Company’s outstanding common stock. During the three months ended December 31, 2019, the Company made an up-front payment of $200.0 million pursuant to the ASR and received and retired an initial 6.4 million shares of the Company’s common stock for an aggregate price of $160.0 million, based on the market price of $25.15 per share of the Company’s common stock on the date of the transaction. During the three months ended March 31, 2020, the ASR was completed, and an additional 1.8 million shares were received for a total repurchase of 8.2 million shares of the Company's common stock at a volume weighted average repurchase price, less an agreed upon discount, of $24.44 per share. The shares received by the Company were retired, accounted for as a reduction to stockholder’s equity in the Condensed Consolidated Balance Sheets, and treated as a repurchase of common stock for purposes of calculating earnings per share.

During the six months ended June 30, 2020, the Company also repurchased 8.5 million shares of its common stock in the open market for an aggregate purchase price of $200.0 million at an average price of $23.70 per share, under the 2018 Stock Repurchase Program.

As of June 30, 2020, there was approximately $1.5 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

Future share repurchases under the 2018 Stock Repurchase Program will be subject to a review of the circumstances at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. The Company's 2018 Stock Repurchase Program may be discontinued at any time.

In addition to repurchases under the 2018 Stock Repurchase Program, the Company also withholds shares of common stock from certain employees in connection with the vesting of stock awards issued to such employees to satisfy applicable tax withholding requirements. Such withheld shares are treated as common stock repurchases in our financial statements as they reduce the number of shares that would have been issued upon vesting. Repurchases associated with tax withholdings were not material during the three and six months ended June 30, 2020 and June 30, 2019.

Note 9. Employee Benefit Plans

Equity Incentive Plans

The Company has stock-based compensation plans pursuant to which it has granted stock options, restricted stock units (“RSUs”), and performance share awards (“PSAs”). The Company also maintains its 2008 Employee Stock Purchase Plan (the “ESPP”) for all eligible employees. As of June 30, 2020, 15.9 million and 12.9 million shares were available for future issuance under the Company's 2015 Equity Incentive Plan (the "2015 Plan") and the ESPP, respectively. In connection with past acquisitions, the Company has also assumed or substituted stock options, RSUs, restricted stock awards ("RSAs"), and PSAs.

RSU, RSA and PSA Activities

The Company’s RSU, RSA and PSA activity and related information as of and for the six months ended June 30, 2020 were as follows (in millions, except per share amounts and years):

	Outstanding RSUs, RSAs and PSAs
	Number of Shares		Weighted Average Grant-Date Fair Value per Share		Weighted Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value

________________________________

^(*)  Includes 2.0 million service-based, 0.8 million performance-based, and 0.4 million market-based RSUs. The number of shares subject to performance-based and market-based conditions represents the aggregate maximum number of shares that may be issued pursuant to the award over its full term. The grant date fair value of RSUs and PSAs was reduced by the present value of dividends expected to be paid on the underlying shares of common stock during the requisite and derived service period as these awards are not entitled to receive dividends until vested.

Employee Stock Purchase Plan

The following table summarizes employee stock purchases through the ESPP (in millions, except per share amounts):

	Six Months Ended June 30,
	2020		2019
Shares purchased	1.4		1.2
Average exercise price per share	$	19.50	$	22.04

The ESPP provides a 24-month offering period with four 6-month purchase periods. A new 24-month offering period commences every six months. The purchase price for the Company’s common stock under the ESPP is 85% of the lower of the fair market value of the shares at (1) the beginning of the applicable offering period or (2) the end of each 6-month purchase period during such offering period. The ESPP will continue in effect until February 25, 2028, unless terminated earlier under the provisions of the ESPP.

Note 11. Income Taxes

The following table provides details of income taxes (in millions, except percentages):

	Three Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Income before income taxes	$	86.1		$	77.8		$	114.4		$	122.3
Income tax provision	$	24.9		$	31.6		$	32.8		$	45.0
Effective tax rate	28.9		%	40.6		%	28.7		%	36.8		%

The Company’s effective tax rate differs from the federal statutory rate of 21% primarily due to the tax impact of state taxes, geographic mix of earnings including foreign-derived intangible income deductions and global intangible low-taxed income, research and development ("R&D") tax credits, tax audit settlements, nondeductible compensation, cost sharing of stock-based compensation, and other transfer pricing adjustments.

On June 7, 2019, the Ninth Circuit Court of Appeals issued an opinion in Altera Corp. v. Commissioner requiring related parties in an intercompany cost-sharing arrangement to share expenses related to stock-based compensation. On February 10, 2020, Altera appealed this decision to the U.S. Supreme Court, which on June 22, 2020, declined to review the decision. Based on the Supreme Court decision to not review the Ninth Circuit Court’s decision, stock-based compensation is subject to cost sharing, and the Company recorded a $18.2 million charge.

The Company’s effective tax rate during the six months ended June 30, 2020 reflects the cumulative impact of cost sharing for stock-based compensation of $18.2 million referenced above, partially offset by a reduction of income tax reserves of $15.2 million, which includes interest of $1.7 million.

The Company's effective tax rate during the six months ended June 30, 2019 reflected the impact of an international realignment and a related write-down of certain deferred tax assets.

As of June 30, 2020, the total amount of gross unrecognized tax benefits was $152.7 million.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by a range of approximately $23.0 million to $44.0 million within the next twelve months due to the completion of tax review cycles in various tax jurisdictions and lapses of applicable statutes of limitations.

Note 13. Commitments and Contingencies

Commitments

Except for the items below, there have been no material changes to the Company's commitments compared to the commitments described in Note 16, Commitments and Contingencies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

Unconditional Purchase Obligations

Unconditional purchase obligations consist of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices. During the second quarter of 2020, the Company amended its existing Master Services Agreement and certain Statements of Work (collectively, the "Agreement") with International Business Machines Corporation ("IBM"), resulting in a $79.4 million reduction in fees payable to IBM over the remaining initial term of the Agreement.

Purchase Commitments with Contract Manufacturers and Suppliers

In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $1,524.3 million as of June 30, 2020.

The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Company’s demand forecast or customer orders. As of June 30, 2020, the Company had accrued $21.3 million based on its estimate of such charges.

Legal Proceedings

In the ordinary course of business, the Company is subject to various pending and potential investigations, disputes, litigations, and legal proceedings. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company intends to aggressively defend itself in any legal matters, and while the outcome of any pending matters is not currently determinable, the Company believes that none of its currently existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or any other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of these events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses.

Basis of Presentation

Basis of Presentation

The Condensed Consolidated Financial Statements of Juniper Networks, Inc. (the “Company” or “Juniper”) were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2019 has been derived from the audited Consolidated Financial Statements at that date. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any future period.

These Condensed Consolidated Financial Statements and accompanying notes should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 (the "Form 10-K"). We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued.

Use of Estimates

The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Actual results could differ materially from those estimates under different assumptions or conditions.

Derivatives

The Company records changes in fair value of interest rate locks in accumulated other comprehensive income (loss) in the consolidated balance sheets, in the period of change. When the forecasted transaction occurs, the Company will start to amortize the accumulated gain or losses included as a component of other comprehensive income (loss) related to the interest rate lock cash flow hedges to interest expense. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) will be reclassified to other income and expense within income statement.

Recently Adopted Accounting Standards and Recent Accounting Standards Not Yet Adopted

Recently Adopted Accounting Standards

Fair Value Measurement: On January 1, 2020, the Company adopted ASU No. 2018-13 (Topic 820) Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds, and modifies certain disclosure requirements for fair value measurements under ASC 820. The Company adopted the standard under the prospective approach for certain modified or new disclosure requirements, and all other amendments in the standard under the retrospective approach. See Note 3, Fair Value Measurements for required disclosures.

Simplifying the Test for Goodwill Impairment: On January 1, 2020, the Company adopted ASU No. 2017-04 (Topic 350) Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. The Company adopted the standard under the prospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Credit Losses on Financial Instruments: On January 1, 2020, the Company adopted ASU 2016-13 (Topic 326) Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments, as further clarified by the Financial Accounting Standards Board (the "FASB") through the issuance of additional related ASUs, which requires the measurement and recognition of current expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model, which requires the use of forward-looking information to calculate credit loss

estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. The Company adopted the standard under the modified retrospective approach. Upon adoption, the standard did not have a material impact on the Consolidated Financial Statements.

Recent Accounting Standards Not Yet Adopted

Reference Rate Reform: In March 2020, the FASB issued ASU No. 2020-04 (Topic 848), Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients and exceptions to the existing guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (SOFR). The standard was effective upon issuance and may generally be applied through December 31, 2022, to any new or amended contracts, hedging relationships, and other transactions that reference LIBOR. The Company is currently evaluating the impact of the transition and disclosure requirements of the standard on its Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes: In December 2019, the FASB issued ASU No. 2019-12 (Topic 740) Income Taxes — Simplifying the Accounting for Income Taxes, which enhances and simplifies various aspects related to accounting for income taxes. This ASU is to be applied on a prospective basis with the exception of certain amendments that are to be applied on either a retrospective or modified retrospective basis. The new standard is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of adoption on its Consolidated Financial Statements.
