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 ofJuniper 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 continuing impact of the COVID-19 pandemic and the global semiconductor shortage, and our ability to successfully manage the demand, supply, and operational challenges associated with the COVID-19 pandemic and the global semiconductor shortage. 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 theU.S. Securities and Exchange Commission , or theSEC . 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 of the pandemic. 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. 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 withU.S. generally accepted accounting principles, orU.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 endedDecember 31, 2020 , or Form 10-K.
Business and Market Environment

To accelerate our strategy, inJanuary 2021 , we acquired Apstra, a leader in intent-based networking, open programmability and automated closed loop assurance for the management of data center networks. We believe our acquisition of Apstra will expand upon our data center networking portfolio to create a compelling solution that will change the customer experience of operating in a modern data center. In addition to our product offerings, we offer software-as-a-service (SaaS), software subscription, and other customer 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. We are executing against our innovation roadmap as each of our industry verticals transitions to cloud architectures. We focus on compelling and differentiated use cases targeting the AI-Driven Enterprise, Automated WAN Solutions, andCloud-Ready Data Center . We believe our understanding of high-performance networking technology and cloud architecture positions us to effectively capitalize on the industry transition to more automated, cost-efficient, and scalable networks. COVID-19 Pandemic Update The COVID-19 pandemic and the containment measures taken by governments and businesses are expected to continue to have a substantial negative impact on businesses around the world and on global, regional, and national economies. As a result, the pandemic has, and may continue to, negatively affect our operations, including as a result of external factors beyond our control such as restrictions on the physical movement of our employees, contract manufacturers, partners, and customers to limit the spread of COVID-19 and the availability and acceptance of COVID-19 vaccines as well as the effectiveness of the vaccines to new variants of this disease. The majority of our global workforce has been working remotely sinceMarch 2020 , and we continue to implement our four-phased approach to office reopening. We will continue to follow the guidance of local and national governments, including monitoring the health of our employees who have returned or will be returning to 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 have a global supply chain, which consists of primary manufacturing partners and component suppliers. During the second quarter of 2021, the supply constraints we continued to experience 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 products we were able to deliver, which negatively impacted our ability to recognize revenue. Challenges to our supply chain due to the impact of the pandemic remain dynamic, and we continue to experience higher logistics costs due to air travel and transport restrictions that limited the availability of flights on which we were able to ship products. 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 pandemic did not have a substantial net impact to our consolidated operating results or our liquidity position in the second quarter of 2021. We continue to generate operating cash flows to meet our short-term liquidity needs, and we expect to continue to maintain access to the capital markets enabled by our strong credit ratings. In the second quarter of 2021, we did not observe any material impairments of our assets or a significant change in the fair value of assets due to the pandemic. We enter the third quarter of fiscal year 2021 with strong momentum and healthy backlog across all verticals. We 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 pandemic. We continue to experience constrained supply, increased logistics costs, and accelerated customer demand, any of which could adversely impact our business, results of operations, and overall financial performance in future periods. 34 -------------------------------------------------------------------------------- Table of Contents Global Semiconductor Shortage There is a worldwide shortage of semiconductors impacting many industries, caused in-part by the COVID-19 pandemic. Similar to others, we are experiencing ongoing component shortages, which have resulted in extended lead times of certain products. We also experienced and may continue to experience increased component costs, which had a negative impact on our gross margin. During the past quarter, we experienced record product orders across all verticals and customer solutions; we believe some of the strength was attributable to industry supply chain challenges that were causing certain customers to place orders early to secure supply when needed. We continued to strengthen our supply chain and have increased inventory levels over the course of the last year. We continue to work closely with our suppliers to further enhance our resiliency and mitigate recent disruptions outside of our control. We believe that even with these actions, extended lead times will likely persist for at least the next few quarters. While the situation is dynamic, at this point in time we believe we will have access to sufficient semiconductor supply to meet our full-year financial forecast. Refer to Part II, Item 1A (Risk Factors) of this Report for further discussion of this risk. 35 -------------------------------------------------------------------------------- Table of Contents Financial Results and Key Performance Metrics Overview The following table provides an overview of our financial results and key financial metrics (in millions, except per share amounts, percentages, and days sales outstanding, or DSO): Three Months Ended June 30, Six Months Ended June 30, 2021 2020 $ Change % Change 2021 2020 $ Change % Change

Service net revenues increased primarily due to strong sales of support contracts, timing of renewals and professional services projects and to a lesser extent, software subscriptions. Of our top ten customers for the second quarter of 2021, four were in Cloud, five were in Service Provider, and one was in Enterprise. Of these customers, two were located outside of theU.S.
•Gross Margin: The gross margin as a percentage of net revenues increased primarily from higher service gross margin mainly due to lower delivery costs and higher revenue.
36 -------------------------------------------------------------------------------- Table of Contents •Operating Margin: The operating income as a percentage of net revenues decreased primarily due to higher personnel-related expenses driven by increases in variable compensation expense and headcount, and higher restructuring charges.
•Operating Cash Flows: Net cash provided by operations increased primarily due to higher collections, partially offset by higher supplier payments and headcount related restructuring costs.
•Capital Return: We continue to return capital to our stockholders. During the six months endedJune 30, 2021 , we repurchased 9.3 million shares of our common stock in the open market at an average price of$25.30 per share for an aggregate purchase price of$235.0 million . During the three and six months endedJune 30, 2021 , we paid a quarterly dividend of$0.20 per share, for an aggregate amount of$64.7 million and$129.9 million , respectively. •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 decreased primarily due to higher revenues.
•Deferred Revenue: Total deferred revenue increased as of
Critical Accounting Policies and Estimates
The preparation of financial statements and related disclosures in conformity withU.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 endedJune 30, 2021 , 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.

For further explanation of our income tax (benefit) provision, see Note 13, 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 theOrganisation 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. 42
