We have experienced reductions in order volume toward the end of the calendar year, as the procurement cycles of these customers slow and network deployment activity is curtailed. This period coincides with the first quarter of our fiscal year. This seasonality in our order flows has typically caused revenue for the first quarter of our fiscal year to be below that of the preceding quarter. These seasonal effects may not apply consistently in future periods and may not be a reliable indicator of our future revenue or results of operations. The effects of the dynamic demand environment we have experienced in recent periods, together with our backlog, have impacted and may continue to impact the traditional seasonality in our business. In addition, the growth as a percentage of our revenue of cloud provider customers, who do not necessarily follow the same seasonal ordering pattern, may also change this pattern in the future.

As we promote our corporate strategy and seek increased customer adoption of our Blue Planet Automation Software, we expect to compete more directly with software vendors and traditional IT services vendors. Competitors for our Blue Planet Automation Software include Cisco, Nokia, Amdocs, ServiceNow, Netcracker, and Ericsson.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Across our markets and segments, the principal competitive factors can include, among others:</span></div><div style="padding-left:49.5pt;text-indent:-11.25pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:7.75pt">functionality, speed, capacity, scalability and performance of network solutions;</span></div><div style="padding-left:49.5pt;text-indent:-11.25pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:7.75pt">the ability to meet business needs and drive successful outcomes, including meeting customer delivery time requirements;</span></div><div style="padding-left:49.5pt;text-indent:-11.25pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:7.75pt">price for performance, cost per bit and total cost of ownership of network solutions;

For example, in 2019, the U.S. Department of Commerce amended the U.S. Export Administration Regulations (&#8220;EAR&#8221;) by adding Huawei Technologies Co., Ltd. (&#8220;Huawei&#8221;) and certain affiliates to the &#8220;Entity List&#8221; for actions contrary to the national security and foreign policy interests of the U.S., resulting in significant new restrictions on the export, reexport and transfer of U.S. regulated technologies and products to Huawei. In 2020, the U.S. Department of Commerce added additional Huawei affiliates to the Entity List, confirmed the expiration of a temporary general license applicable to Huawei, and amended the foreign direct product rule under the EAR in a manner that significantly expanded its application to Huawei. Separately, the U.S. government has taken steps to restrict federal agencies from doing business with, and U.S. wireless carriers from using federal subsidies to buy equipment from, Huawei and ZTE. The U.S. government has also encouraged other governments to consider similar restrictions. These actions, among others, have resulted in escalating tensions between the U.S. and China and retaliation by China, including a recent prohibition on export of certain rare minerals, and introduce a risk that the Chinese government may take further steps to retaliate against U.S. industries or companies. Trade regulations limiting or banning sales into, or purchases from, certain countries or companies have also impacted and may in the future impact our ability to transact business in certain countries and with certain customers. In addition, the incoming U.S. administration has announced an intent to impose additional tariffs, including tariffs on imports from Canada, Mexico, and China.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Patents, Trademarks and Other Intellectual Property Rights</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The success of our business and technology leadership depends significantly on our proprietary and internally developed technology.

Our budgeted expense levels are based on our intent to invest to maintain or increase our technology advantage, our visibility into customer spending plans, and our projections of future revenue and gross margin. Visibility into customer spending levels can be uncertain, spending patterns are subject to change, and reductions in our expense levels can take significant time to implement. Historically, a significant portion of our quarterly revenue was generated from customer orders received during that same quarter (which we refer to as &#8220;book to revenue&#8221;) and was therefore less predictable and subject to fluctuation due to a quarterly shortfall in orders from expectations. During fiscal 2022, however, we generated a significant backlog of customer orders as a result of supply chain constraints and, during fiscal 2023, our revenue grew as we consumed a significant portion of this backlog. Customer order volumes began to moderate in the fourth quarter of fiscal 2022, and we experienced order levels below revenue during fiscal 2023 and the first half of fiscal 2024 and, as a result, our backlog decreased. We expect our backlog to continue to reduce in fiscal 2025. As that happens, we expect our reliance upon securing quarterly book to revenue orders to grow and those orders to represent a more typical composition of our quarterly revenue over time. Our future revenue growth will depend, in part, on securing increased orders, particularly book to revenue orders. </span></div><div style="text-indent:18pt"><span><br/></span></div><div

A cloud provider customer accounted for approximately&#160;13.3% of our total revenue for fiscal 2024 and 12.8% of our total revenue for fiscal 2023, and AT&amp;T accounted for approximately 11.8% of our total revenue for fiscal 2024 and 10.6% of our total revenue for fiscal 2023.

These dynamics have in the past had an adverse effect on network spending levels by certain of our largest customers and they could materially adversely affect our business and results of operations. Consequently, our financial results and our ability to grow our business are closely correlated with the spending of a relatively small number of customers. Our business and results of operations could be materially adversely impacted by the loss of a large customer within or outside of these customer segments as well as by reductions in spending or capital expenditure budgets, changes in network deployment plans, or changes in consumption models for acquiring networking solutions by our largest customers.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">We face intense competition that could impact our sales and results of operations.

Our industry has historically been dominated by a small number of very large vendors, some of which have substantially greater financial, marketing and research and development resources, broader product offerings and more established relationships with service providers and other customer segments than we do. Moreover, acquisition activity among our competitors and peers has increased. For example, in 2024 Nokia announced its proposed acquisition of Infinera. Consolidation in our industry may result in competitors with greater resources, pricing flexibility, or other competitive benefits. We also compete with a number of smaller companies that provide significant competition for specific products, applications, customer segments or geographic markets.

Accordingly, there is no guarantee that our new products or product enhancements will achieve market acceptance or that the timing of market adoption will be as predicted. As a general matter, there is a significant possibility&#160;that some of our development decisions, including significant expenditures on acquisitions, research and development, or investments in technologies, will not meet our expectations, and that our investment in some projects will be unprofitable.

We must regularly compete for and win business with existing customers across all of our customer segments. In addition, cloud providers tend to operate on shorter procurement cycles than some of our traditional customers, which can require us to compete to re-win business with these customers more frequently than required with other customers segments. Accordingly, there is no assurance that we will maintain our incumbency with any given customer or that our revenue levels from a customer in a particular period can be achieved in future periods.

These selling efforts often involve a significant commitment of time and resources that may include extensive product testing, laboratory or network certification, network or region-specific product certification and homologation requirements for deployment in networks. Even after a customer awards its business to us or decides to purchase our solutions, the length of time before deployment can vary depending on the customer&#8217;s schedule, site readiness, the size of the network deployment, the degree of custom configuration required and other factors. Additionally, these sales also often involve protracted and sometimes difficult contract negotiations in which we may deem it necessary to agree to unfavorable contractual or commercial terms that adversely affect pricing, expose us to penalties for delays or non-performance, and require us to assume a disproportionate amount of risk. To maintain incumbency with key customers, we have in the past and may in the future be required to offer discounted pricing, make commercial concessions or offer less favorable terms as compared to our historical business arrangements with these customers. We may also be requested to provide deferred payment terms, vendor or third-party financing or other alternative purchase structures that extend the timing of payment. Alternatively, customers may insist on terms and conditions that we deem too onerous or not in our best interest, and we may be unable to reach a commercial agreement. As a result, we may incur substantial expense and devote time and resources to potential sales opportunities that never materialize or result in lower than anticipated sales and gross margin. </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">25</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#ic6552f1a443249e1892c80545873e90a_7">Table of </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#ic6552f1a443249e1892c80545873e90a_7">Contents</a></span></div></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Accurately matching necessary inventory levels to customer demand within the current environment is challenging, and we may incur additional costs or be required to write off significant inventory that would adversely impact our results of operations.</span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From the second quarter of fiscal 2021 through the third quarter of fiscal 2022, we received unprecedented orders for our products and services, during a period when the supply environment was constrained. We took a number of steps to mitigate these challenges, including extending our purchase commitments and placing non-cancellable, advanced orders with or through suppliers, particularly for long lead-time components. As of November&#160;2, 2024, we had $1.7&#160;billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. We also expanded our manufacturing capacity and accumulated available raw materials inventory to prepare us to be able to produce finished goods more quickly as supply constraints eased for those components in shorter supply. As a result of this strategy, our inventory increased from $374.3 million at the end of fiscal 2021 to $1.1 billion at the end of fiscal 2023. While our inventory reduced to $820.4 million at the end of fiscal 2024, these inventory practices and their associated costs have had, and could in the future continue to have, an adverse impact on our cash from operations.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">These inventory practices, particularly when considered in the context of our backlog, further introduce obsolescence risk that can impact our results of operations and financial condition. In addition, during fiscal 2023 and fiscal 2024, certain customers, including communications service providers and cable and multiservice operators in North America, that had earlier placed significant advanced orders, rescheduled deliveries for or cancelled a portion of such orders. Accordingly, our inventory needs for a particular period can fluctuate and be difficult to predict. If our customers were to cancel or delay orders for extended periods, inventory could become obsolete, and we could be required to write off or write down the inventory associated with those orders. In addition, if customers were to cancel or delay existing or forecasted orders for which we have significant outstanding commitments to our contract manufacturers or suppliers, we may be required to purchase inventory under these commitments that we are unable to sell. If we are required to write off or write down a significant amount of inventory, our results of operations for the applicable period would be materially adversely affected. For example, we recorded charges for excess and obsolete inventory of $77.3 million, $29.5 million and $16.2 million in fiscal 2024, 2023 and 2022, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products primarily sold to communications service providers. Our inability to effectively manage the matching of inventory with customer demand, particularly within any supply constrained environment, could adversely impact our results of operations and financial condition, and could result in loss of revenue, increased costs, or delays that could adversely impact customer satisfaction.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:112%">If we are unable to adapt our business and solutions offerings to the evolving consumption models of our customers, our competitive position and results of operations could be adversely affected.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Growing bandwidth demands and network operator efforts to reduce costs are resulting in a diverse range of approaches to the design and procurement of network infrastructure. We refer to these different approaches as &#8220;consumption models.&#8221; These consumption models can include: the traditional systems procurement of fully integrated solutions including acquiring hardware, software and services from the same vendor; the procurement of a fully integrated hardware solution from one vendor with the separate use of a network operator&#8217;s own software-denied network-based controller; the procurement of an integrated photonic line system with open interfaces from one vendor and the separate or &#8220;disaggregated&#8221; procurement of modem technology from a different vendor; or the development and use of published reference designs and open source specifications for the procurement of &#8220;white box&#8221; hardware to be used with open source software. In parallel, network operators are also exploring procurement alternatives for software solutions, ranging from integrated and proprietary software platforms to fully open source software. Some network operators are pursuing the deployment of smaller form factor, pluggable modem technology, particularly within switching and routing solutions, as an alternative to integrated optical networking platforms. Other network operators, including certain of our cloud provider customers, are playing a leading role in the transition to software-defined networking, the standardization of communications network solutions and the assembly of their own hardware platforms based on enabling third-party components. We believe that the potential for different approaches to the procurement of networking infrastructure will require network operators and vendors to evolve and broaden their existing solutions and commercial models over time. If we are unable to adapt our business to these new consumption models and offer attractive solutions and commercial models that meet our customers&#8217; needs, our competitive position and results of operations could be adversely affected.</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:107%">As we introduce technologies that enable us to enter into new markets, we may experience difficulty monetizing these new solutions and be exposed to increased or new forms of competition.</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:107%">A key part of our strategy is to expand our addressable market into complementary and adjacent network applications by investing in new technologies, including solutions related to data center, PON, routing and switching, and automation software and services.

These and other risks, unanticipated liabilities, or costs associated with the sales of our WaveLogic coherent technology could harm our reputation and adversely affect our business and our results of operations.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:107%">Supply chain challenges and constraints, including for semiconductor components, could adversely impact our growth, gross margins and financial results. </span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:107%">In the face of demand across a range of industries, global supply for certain raw materials and components, including, in particular, semiconductor, integrated circuits, and other electronic components used in most of our products, experienced substantial constraint and disruption in recent prior periods. As a result, we experienced significant component shortages, extended lead times, increased costs, and unexpected cancellation or delay of previously committed supply of key components across our supplier base. While reliability of supply has improved, extended lead times and elevated component costs could continue to adversely impact our revenue, our cost of goods sold, and our ability to reduce the cost to produce our products in a manner consistent with prior periods. It is unclear when the supply environment will fully stabilize, and there can be no assurance that we will not experience similar supply challenges or constraints in future periods. These challenges have affected, and could adversely affect, component availability, lead times and cost, which can adversely impact our revenue and have an impact on customer purchasing decisions. Supply chain challenges could also impact customer satisfaction or future business opportunities with customers, and result in increased use of cash, engineering design changes, and delays in new product introductions, each of which could adversely impact our business and financial results.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Our exposure to the credit risks of our customers and resellers may make it difficult to collect receivables and could adversely affect our revenue and operating results. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In the course of our sales to customers and resale channel partners, we may have difficulty collecting receivables, and our business and results of operations could be exposed to risks associated with uncollectible accounts.

Some of our products can be fully tested only when deployed in communications networks or when carrying traffic, and software products may contain bugs that can interfere with expected performance. As a result, undetected defects or problems affecting quality, interoperability, reliability, security and performance are often more acute for initial deployments of new products or enhancements. We have recently launched, or are in the process of launching, a number of new hardware and software offerings, including new evolutions of our WaveLogic coherent optical modem technology and new Routing and Switching platforms. Unanticipated product performance problems can relate to the design, manufacturing, installation, operation and interoperability of our products. Undetected errors can also arise as a result of defects in third-party technologies, components or software, including open source software, or manufacturing, installation or maintenance services supplied by third parties. The introduction of new and complex technologies, such as AI, can also increase security risks and the risk of defects. From time to time, we have had to replace certain components, provide software remedies or other remediation in response to defects or bugs, and we may have to do so again in the future. Such remediation costs could materially adversely impact our business and results of operations. In addition, we have encountered and may continue to encounter unanticipated security vulnerabilities relating to our technology, including as a result of the activities of our supply chain and our use of third-party software. Communications technologies, given their capability to transmit sensitive information, have frequently been the target of attacks from a range of threat actors including nation states and other malicious parties.

Our international operations are subject to complex foreign and U.S. laws and regulations, including trade regulations, anti-bribery and corruption laws, antitrust or competition laws, and data privacy laws, such as the GDPR, among others. In particular, recent years have seen a substantial increase in anti-bribery law enforcement activity by U.S. regulators, and we currently operate and seek to operate in many parts of the world that are recognized or perceived as having greater potential for corruption. Violations of any of these laws and regulations could result in fines and penalties, criminal sanctions against us or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in certain geographies, and significant harm to our business reputation. Our policies and procedures to promote compliance with these laws and regulations and, to mitigate these risks, may not protect us from all acts committed by our employees or third-party vendors, including contractors, agents and services partners or from the misinterpretation or changing application of such laws. Additionally, the costs of complying with these laws (including the costs of investigations, auditing and monitoring) could adversely affect our current or future business.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our business, operations and financial results could also be adversely impacted by instability, disruption or destruction in a significant geographic region, including as a result of war, terrorism, riot, civil insurrection or social unrest; natural or man-made disasters; severe weather events; public health emergencies; or economic instability or weakness. For example, in February 2022, armed conflict escalated between Russia and Ukraine. The United States and certain other countries have imposed sanctions on Russia (and Belarus for its support of Russia) and could impose further sanctions, which could damage or disrupt international commerce and the global economy. We are complying with a broad range of U.S. and international sanctions and export control requirements imposed on Russia and, in March 2022, we announced our decision to suspend our business operations in Russia. Although this decision did not materially impact our results of operations for fiscal 2022 or 2023 due to the limited amount of business that we conducted in Russia historically, it is not possible to predict the broader or longer-term consequences of this conflict, which could include further sanctions, export control and import restrictions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates and financial markets. In addition, the conflict between Israel and groups based in surrounding regions, and related regional impacts have resulted in damage to submarine cables in the Red Sea and disruption of networks using those cables, which could impact future projects by our customers in this region. Such geopolitical instability and uncertainty could have a negative impact on our ability to sell to, ship products to, collect payments from, and support customers in certain countries and regions based on trade restrictions, sanctions, embargoes and export control law restrictions, and logistics restrictions including closures of air space, and could increase the costs, risks and adverse impacts from supply chain and logistics challenges. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The success of our International sales and operations will depend, in large part, on our ability to anticipate and manage these risks effectively.

Due to our global presence, a portion of our revenue, operating expense and assets and liabilities are non-U.S. Dollar denominated and therefore subject to foreign currency fluctuation. We face exposure to currency exchange rates as a result of the growth in our non-U.S. Dollar denominated operating expense in Canada, Europe, Asia and Latin America. 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 where we sell in U.S. Dollars, and a weakened U.S. Dollar could increase the cost of local operating expenses and procurement of materials or service that we purchase in foreign currencies. From time to time, we hedge against currency exposure associated with anticipated foreign currency cash flows or assets and liabilities denominated in foreign currency. Such attempts to offset the impact of currency fluctuations are costly, and we cannot hedge against all foreign exchange rate volatility. Losses associated with these hedging instruments and the adverse effect of foreign currency exchange rate fluctuation may negatively affect our results of operations. </span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:115%">Risks Related to Our Operations and Reliance on Third Parties</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:115%">We may experience delays in the development and production of our products that may negatively affect our competitive position and business.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our hardware and software networking solutions, including our WaveLogic modem technology and the components thereof, are based on complex technology, and we can experience unanticipated delays in developing, manufacturing and introducing these solutions to market. Delays in product development efforts by us or our third-party partners may affect our reputation with customers, affect our ability to capture market opportunities and impact the timing and level of demand for our products. We are regularly introducing new products and enhancements and each step in their development cycle presents serious risks of failure, rework or delay, any one of which could adversely affect the cost-effectiveness and timely development of our products. Reworks, in particular, if required, can be a very expensive and time-consuming effort. We may encounter delays relating to engineering development activities and software, design, sourcing and manufacture of critical components, and the development of prototypes. The development of new technologies may increase the complexity of supply chain management or require the acquisition, licensing or interworking with the technology of third parties. In addition, intellectual property disputes, failure of critical design elements and other execution risks may delay or even prevent the release of these products.

In August 2020, the U.S. Department of Commerce added additional Huawei affiliates to the Entity List, confirmed the expiration of a temporary general license applicable to Huawei and amended the foreign direct product rule in a manner that represents a significant expansion of its application to Huawei. More recently, the U.S. Department of Commerce has expanded the scope of the EAR by amending the foreign direct product rule, resulting in more products made outside the United States becoming subject to the EAR for purposes of exports or transfers to certain countries and/or parties, which increases compliance risks and licensing obligations for companies dealing with such products. Several of our third-party component suppliers, including certain sole and limited source suppliers, sell products to Huawei and, in some cases, Huawei is a significant customer for such suppliers. At this time, there can be no assurance regarding the scope or duration of these restrictions, including the foreign direct product rule, or further actions imposed on Huawei and other companies located and operating in China, and any future impact on our suppliers. Any continued restriction on our suppliers&#8217; ability to make sales to Huawei and other companies may adversely impact their businesses and financial position. In addition, China is in the midst of executing a five-year plan to improve China&#8217;s capabilities in the optoelectronics industry. There can be no assurance that this initiative, or similar efforts in China such as the Made in China 2025 initiatives (and actions taken by the U.S. government in response to such efforts), will not have an adverse impact on the business of our suppliers or our access to necessary components. These and similar industry, market and regulatory disruptions affecting our suppliers could, in turn, expose our business to loss or lack of supply or discontinuation of components that could result in lost revenue, additional product costs, increased lead times and deployment delays that could harm our business and customer relationships.

Substantial expense or charges resulting from restructuring activities could adversely affect our results of operations and use of cash in those periods in which we undertake such actions. </span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:112%">If we are unable to attract and retain qualified personnel, we may be unable to manage our business effectively.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our future success and ability to maintain a technology leadership position depend upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. Competition to attract and retain highly skilled technical, engineering and other personnel with experience in our industry is intense, and our employees have been the subject of targeted hiring by our competitors. Competition is particularly intense in certain jurisdictions where we have research and development centers, including the Silicon Valley area of northern California, and for engineering talent generally. The lasting impact of the COVID-19 pandemic has resulted in higher employee costs, increased attrition, and significant shifts in the labor market and employee expectations. We may experience difficulty retaining and motivating existing employees and attracting qualified personnel to fill key positions. In addition, labor shortages and employee mobility may make it more difficult to hire and retain employees. None of our executive officers is bound by an employment agreement for any specific term. Because we rely on equity awards as a significant component of compensation, particularly for our executive team, a lack of positive performance in our stock price, reduced grant levels, or changes to our compensation program may adversely affect our ability to attract and retain key employees. If we are unable to attract and retain qualified personnel, we may be unable to manage our business effectively, and our operations and financial results could suffer. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, a number of our team members are foreign nationals who rely on visas or work-entry permits in order to legally work in the United States and other countries.

Our business may be materially adversely affected if legislative or administrative changes to immigration or visa laws and regulations impair our hiring processes or projects involving personnel who are not citizens of the country where the work is to be performed.

The frequency, sophistication and unpredictability of cybersecurity events globally have increased, and can be more acute during times of geopolitical tension or instability between countries. In addition, companies in the technology industry, and in particular, manufacturers of networking and communications products, have been increasingly subjected to a wide variety of data security incidents, including cyber-attacks, attacks against products, and other attempts to gain unauthorized access to network assets, infrastructure or sensitive information. Our network systems, devices, storage and other business applications, and those that we rely on, and that are maintained by our third-party providers, have been in the past, and may be in the future, subjected to security incidents including attack, exploitation, intrusion, disruption and other malfeasance or attempts to gain unauthorized access or conduct other unauthorized activities. Further, our network systems, devices, storage and other business applications may be targeted for data security incidents as a vicarious method to target our customers. Such data security incidents may be caused by malice or negligence from either third-party or internal actors. These threats arise from actions by nation states, independent hackers, hacktivist groups, organized cybercrime entities, and other third parties, as well as from malicious actors from within or supporting our organization.

The U.S. government has raised tariffs, and imposed new tariffs, on a wide range of imports of Chinese products, including component elements of our solutions and certain finished goods products that we sell. For example, U.S. tariff policy involving imports from China was subject to a lengthy, now-completed review by the U.S. government in 2023 and the first three quarters of 2024, and the incoming U.S. administration has announced an intent to impose an additional 10% tariff on all imports from China. The U.S. government has also introduced broad new restrictions on imports from China allegedly manufactured with forced labor, and the EU and the UK have recently adopted similar restrictions. China has retaliated by raising tariffs, and imposing new tariffs, on certain exports of U.S. goods to China, introducing blocking measures to restrict the ability of domestic companies to comply with U.S. trade restrictions, and recently prohibiting the export of certain rare minerals from China to the United States, and could take further steps to retaliate against U.S. industries or companies.

The situation involving U.S.-China trade relations remains volatile and uncertain, and there can be no assurance that further actions by either country will not have an adverse impact on our business, operations and access to technology, or components thereof, sourced from China.

However, the incoming U.S. administration announced an intent to impose tariffs on imports from Canada, Mexico, and China. We estimate that products or components that make up a significant portion of our revenue are either manufactured in or distributed from Mexico. Although the ultimate scope and timing of any such tariffs is indeterminable, if implemented, they could have a significant impact on our financial condition and results of operations. Based on our manufacturing practices and locations, there can be no assurance that any future executive or legislative action in the United States or other countries relating to tax policy and trade regulation would not adversely affect our business, operations and financial results. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Government regulation of usage, import or export of our products, or our technology within our products, changes in that regulation, or our failure to obtain required approvals for our products, could harm our international and domestic sales and adversely affect our revenue and costs of sales. Failure to comply with such regulations could result in enforcement actions, fines, penalties or restrictions on export privileges. In addition, costly tariffs on our equipment, restrictions on importation, trade protection measures and domestic preference requirements of certain countries could limit our access to these markets and harm our sales.

Similarly, changes in regulatory tariff requirements or other regulations relating to pricing or terms of carriage on communications networks could slow the development or expansion of network infrastructures and adversely affect our business, operating results, and financial condition. Legislators and regulators have also enacted and may in the future enact laws and rules that impose significant fines or other liability on communications companies that experience cyber attacks, information or security breaches, or technology disruptions or failures. Such events may therefore have an adverse effect on our company or our customers&#8217; businesses. </span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Separately, certain of our cloud provider customers have been the subject of regulatory and other government actions, including inquiries and investigations, formal or informal, by competition authorities in the United States, Europe and other </span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">38</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#ic6552f1a443249e1892c80545873e90a_7">Table of </a><a style="color:#0000ff;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline" href="#ic6552f1a443249e1892c80545873e90a_7">Contents</a></span></div></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">jurisdictions.

These laws and regulations directly impact us and may indirectly impact our operations as a result of required compliance by our customers or supply chain. Inconsistency across laws and regulations may affect the costs of compliance with such laws and regulations. Assessments of the potential impact of future climate change legislation, regulation, and international treaties and accords are uncertain, given the wide scope of potential regulatory change in countries in which we operate. Increased public awareness and worldwide focus on environmental and climate changes may lead to new or strengthened regulations, legislation or other governmental requirements or industry standards, such as increased demand to meet voluntary criteria related to reduction of greenhouse gas emissions and increasing energy efficiency. These requirements will, and other increased regulation of climate change concerns could, subject us to additional costs and restrictions, and could require us to make certain changes to our manufacturing practices and product designs, which could negatively impact our business, results of operations, financial condition and competitive position. If we were to violate or become liable under these laws or regulations, we could incur fines, costs related to damage to property or personal injury and costs related to investigation or remediation activities.</span></div><div style="margin-bottom:10pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our product design efforts and the manufacturing of our products are also subject to evolving requirements relating to the presence of certain materials or substances in our equipment, including regulations that make producers for such products financially responsible for the collection, treatment and recycling of certain products. For example, our operations and financial results may be negatively affected by environmental regulations, such as the WEEE and RoHS regulations that have been adopted by the EU. Compliance with these and similar environmental regulations may increase our cost of designing, manufacturing, selling and removing our products. The SEC requires disclosure regarding the use of &#8220;conflict minerals&#8221; mined from the Democratic Republic of the Congo and adjoining countries (the &#8220;DRC&#8221;) and disclosure with respect to procedures regarding a manufacturer&#8217;s efforts to prevent the sourcing of such minerals from the DRC. Certain of these minerals are present in our products. SEC rules implementing these requirements may have the effect of reducing the pool of suppliers that can supply &#8220;conflict free&#8221; components and parts, and we may not be able to obtain conflict free products or supplies in sufficient quantities for our operations.

While it is uncertain whether the United States will enact legislation to adopt Pillar Two, certain countries in which we operate have enacted legislation, and other countries are in the process of introducing draft legislation to implement the minimum tax directive. Many aspects of Pillar Two will be effective for Ciena beginning in fiscal 2025 with additional components becoming effective beginning in fiscal 2026. Pillar Two taxes are considered an alternative minimum tax accounted for as a period cost that will impact the effective tax rate in the year the Pillar Two tax obligation arises. Therefore, deferred taxes will not be recognized or adjusted for the estimated effects of future minimum taxes. We have assessed the impact of Pillar Two and do not currently anticipate any material effect on our effective tax rate, financial results or cash flows for fiscal 2025 based on currently enacted laws; however, our analysis is ongoing as the OECD continues to release additional guidance and countries enact legislation.

Keeping pace with the market&#8217;s demand for technology innovation requires considerable research and development investment capacity and expenditures, and research and development spending represented 19.1% of our operating expenses in fiscal 2024. During fiscal 2024, we invested $767.5 million in research and development activities, an increase of 2.3% compared to fiscal 2023. In particular, in an effort to capture certain market opportunities created by the impact of AI on networks, in fiscal 2024 we continued to innovate, increase the performance of, and enhance the capabilities for our leading WaveLogic coherent modem technology in multiple form factors.

We believe some portion of these orders reflected customer acceleration of future orders due to long lead times during the constrained supply environment of that period, as well as orders that were delayed due to the dynamics of the COVID-19 pandemic. These order volumes resulted in significant revenue growth in fiscal 2023. Our order volumes began to moderate in the fourth quarter of fiscal 2022, and we experienced order levels below revenue during fiscal 2023 and the first half of fiscal 2024, particularly from our communications service provider customers. We believe this was, in part, due to communications service providers in North America working through relatively high levels of inventory previously acquired, which was made more difficult due to challenges installing and deploying equipment. In addition, in certain international geographies, we believe that caution driven by macroeconomic concerns and market-specific issues contributed to lower-than-expected order volumes from communications service providers during fiscal 2024. As a result of these dynamics, our revenue for fiscal 2024 was lower than our revenue in fiscal 2023.

The geographic distribution of our revenue can fluctuate significantly from period to period, and the timing of revenue recognition for large network projects, particularly outside of the United States, can result in large variations in geographic revenue results in any particular period. The decrease in our Americas region revenue for fiscal 2024 was primarily driven by decreased sales in Canada and the United States. The decrease in our APAC region revenue for fiscal 2024 was primarily driven by decreased sales in Australia, India, Singapore and South Korea. The increase in our EMEA region revenue for fiscal 2024 was partially offset by sales decreases in Great Britain and the Netherlands. The following table reflects our geographic distribution of revenue, which is principally based on the relevant location for the delivery of our products and performance of services.

Our gross margin can fluctuate and be adversely impacted depending on our revenue concentration within a particular segment, product line, geography, or customer, as well as our success in selling software in a particular period. Our gross margin remains highly dependent on our continued ability to drive annual product cost reductions relative to the price erosion that we regularly encounter in our markets. Moreover, we are often required to compete with aggressive pricing and commercial terms, and, to secure business with new and existing customers, we may agree to pricing or other unfavorable commercial terms that adversely affect our gross margin. Success in gaining market share and winning new business can result in additional pressure on gross margin from these pricing dynamics and the early stages of these network deployments. Early stages of new network builds also often include an increased concentration of lower margin &#8220;common&#8221; equipment, photonics sales and installation services, with the intent to improve margin as we sell channel cards and maintenance services to customers as they add capacity and need to monitor their networks. Gross margin can be impacted by technology-based price compression and the introduction or substitution of new platforms with improved price for performance as compared to existing solutions that carry higher margins. Gross margin can also be impacted by changes in expense for excess and obsolete inventory and warranty obligations.</span></div><div style="text-indent:18pt"><span><br/></span></div><div

The assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to allocate purchase price consideration properly between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#8217;s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Our significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur that may affect the accuracy or validity of such estimates. During fiscal 2022, we completed the acquisitions of AT&amp;T&#8217;s Vyatta Software Technology (&#8220;Vyatta&#8221;) and Xelic, Inc. (&#8220;Xelic&#8221;) for an aggregate purchase price of $64.1&#160;million.

Awards with performance-based vesting conditions require the achievement of certain financial or other performance criteria or targets as a condition to the vesting, or acceleration of vesting. We recognize the estimated fair value of performance-based awards as share-based expense over the performance period, using graded vesting, which considers each performance period or tranche separately. At the end of each reporting period, for performance based awards not subject to total stockholder return, we reassess the probability of achieving the performance targets and the performance period required to meet those targets, and the expense is adjusted accordingly. Determining whether the performance targets will be achieved involves judgment, and the estimate of expense may be revised periodically based on changes in the probability of achieving the performance targets. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation cost is reversed. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Share-based compensation expense is taken into account based on awards granted.

In an effort to limit our exposure to delivery delays and to satisfy customer needs, we purchase inventory based on forecasted sales across our product lines. Beginning in the second half of fiscal 2021, we started placing significant, advanced orders for supply of certain long lead time components to address our expected customer demand for fiscal 2022 and the then-emerging supply chain challenges. During the second half of fiscal 2023, supply for certain long lead time components began to stabilize, and the need to place advance orders decreased for these components.

Our products are generally covered by a warranty for periods ranging from one to five years.

See Notes 15 and 18 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information relating to our 2030 New Term Loan. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Foreign Currency Exchange Risk. </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a global concern, our business and results of operations are exposed to and can be impacted by movements in foreign currency exchange rates. Because we sell globally, some of our sales transactions and revenue are non-U.S. Dollar denominated, with the Euro, Indian Rupee, and Canadian Dollar being our most significant foreign currency revenue exposures. If the U.S. Dollar strengthens against these currencies, our revenue for these transactions reported in U.S. Dollars would decline. For our U.S. Dollar denominated sales, an increase in the value of the U.S. Dollar would increase the real costs of our products to customers in markets outside the United States, which could impact our competitive position. During fiscal 2024, approximately 14.3% of revenue was non-U.S. Dollar denominated. During fiscal 2024 as compared to fiscal 2023, the U.S. Dollar fluctuated against a number of foreign currencies with minimal impact as compared to fiscal 2023.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">With regard to operating expense, our primary exposure to foreign currency exchange risk relates to the Canadian Dollar, Indian Rupee and Euro. If these foreign currencies strengthen against the U.S. Dollar, costs reported in U.S. Dollars will increase. During fiscal 2024, approximately 48.7% of our operating expense was non-U.S. Dollar denominated. During fiscal 2024 as compared to fiscal 2023, the U.S. Dollar primarily strengthened against a number of foreign currencies with minimal impact as compared to fiscal 2023.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time, we use foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less and are designated as cash flow hedges. At the inception of the cash flow hedge, and on an ongoing basis, we assess whether the forward contract has been effective in offsetting changes in cash flows attributable to the hedged risk during the hedging period. The derivative&#8217;s net gain or loss is initially reported as a component of accumulated other comprehensive loss and, upon the occurrence of the forecasted transaction, it is subsequently reclassified to the line item in the Consolidated Statements of Operations to which the hedged transaction relates. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During fiscal 2024, we recorded $11.7 million in foreign currency exchange losses, as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#8217;s functional currency, and the re-measurement adjustments were recorded in interest and other income, net on our Consolidated Statements of Operations. From time to time, we use foreign currency forwards to hedge these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net. During fiscal 2024, we recorded gains on non-hedge designated foreign currency forward contracts of $1.4 million.

Management records a provision for excess and obsolete inventory when an impairment has been identified and has a reserve for excess and obsolete inventory of $107.2 million as of November 2, 2024. Management writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in the Company&#8217;s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%">The principal considerations for our determination that performing procedures relating to the reserve for excess and obsolete inventory is a critical audit matter are the significant judgment by management when developing their estimate, which in turn led to a high degree of auditor judgment, subjectivity, and effort to perform procedures and evaluate the audit evidence obtained relating to the assumptions regarding future demand. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the Company&#8217;s evaluation of the reserve for excess and obsolete inventory, including controls over the assumptions used within the model. These procedures also included, among others, testing management&#8217;s process for determining the reserve for excess and obsolete inventory. This included evaluating the appropriateness of the inventory reserve model and the reasonableness of the significant assumptions relating to the future demand. Evaluating the assumptions related to future demand involved evaluating whether the assumptions used were reasonable considering historical demand and expectations regarding future demand. Testing management's process for determining future demand included procedures to evaluate the reliability, completeness and relevance of management's data used in the future demand assumption. Testing the relevance and reliability of the data included evaluating the reasonableness of the long-term demand forecasts and historical activity.</span></div><div><span><br/></span></div><div

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order.

SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers.

Ciena elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole, and thus the capitalized costs of obtaining a purchase order is applied, even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div></ix:continuation><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Warranty Accruals</span></div><div><span><br/></span></div><ix:nonNumeric contextRef="c-1" name="us-gaap:StandardProductWarrantyPolicy" id="f-460" escape="true"><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue.

In addition, tax authorities periodically audit Ciena&#8217;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2020 through 2023, in Canada for 2014, and in the United Kingdom for 2016 through 2022. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#8217;s consolidated financial position, results of operations or cash flows. Ciena&#8217;s major tax jurisdictions and the earliest open tax years are as follows: United States (2021), United Kingdom (2016), Canada (2014), and India (2020). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards.

For the periods presented, future demand was calculated using both customer backlog and future forecasted sales. Generally, Ciena&#8217;s customers may cancel or change their orders with limited advance notice, or they may decide not to accept its products and services. Ciena writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena&#8217;s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During fiscal 2024, fiscal 2023 and fiscal 2022, Ciena recorded a provision for excess and obsolescence of $<ix:nonFraction unitRef="usd" contextRef="c-1" decimals="-5" name="us-gaap:InventoryWriteDown" scale="6" id="f-1072">77.3</ix:nonFraction> million, $<ix:nonFraction unitRef="usd" contextRef="c-12" decimals="-5" name="us-gaap:InventoryWriteDown" scale="6" id="f-1073">29.5</ix:nonFraction> million, and $<ix:nonFraction unitRef="usd" contextRef="c-13" decimals="-5" name="us-gaap:InventoryWriteDown" scale="6" id="f-1074">16.2</ix:nonFraction> million, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products primarily sold to communications service providers.

The assets acquired, liabilities assumed, contractual contingencies, and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#8217;s use of the asset and the appropriate discount rates for a market participant. Ciena&#8217;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when </span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.<br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Use of Estimates</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The preparation of the financial statements and related disclosures in conformity with Generally Accepted Accounting Principles (&#8220;GAAP&#8221;)&#160;requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes.

Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#8217;s cost basis, and Ciena&#8217;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value.

Operating segments are defined as components of an enterprise that engage in business activities that earn revenue and incur expense, for which discrete financial information is available, and for which such information is evaluated regularly by the chief operating decision maker for purposes of allocating resources and assessing performance. Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services.

Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year. Ciena also tests goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. </span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Annually, Ciena tests goodwill impairment qualitatively, or quantitatively by comparing the fair value of the reporting unit with the unit&#8217;s carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If Ciena is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Long-lived Assets</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Long-lived assets include equipment, building, furniture and fixtures, operating right-of-use (&#8220;ROU&#8221;) assets, finite-lived intangible assets and maintenance spares. Ciena tests long-lived assets for impairment whenever triggering events or changes in circumstances indicate that the asset&#8217;s carrying amount is not recoverable from its undiscounted cash flows. An impairment loss is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value.

The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration.

Operating leases are included in the Operating ROU assets, Operating lease liabilities and Long-term operating lease liabilities on the Consolidated Balance Sheets.

Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses, such as common area maintenance and utilities.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term.

Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method.

If Ciena cannot effectively manage these manufacturers or forecast future demand, or if these manufacturers fail to deliver products or components on time, Ciena&#8217;s business and results of operations may suffer.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Revenue Recognition</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena recognizes revenue when control of the promised products or services is transferred to its customer, in an amount that reflects the consideration to which Ciena expects to be entitled in exchange for those products or services.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena determines revenue recognition by applying the following five-step approach:</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt">identification of the contract, or contracts, with a customer;</span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt">identification of the performance obligations in the contract;</span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt">determination of the transaction price;</span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt">allocation of the transaction price to the performance obligations in the contract; and</span></div><div style="padding-left:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt">recognition of revenue when, or as, Ciena satisfies a performance obligation.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Generally, Ciena makes sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of Ciena&#8217;s products and services. These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="margin-top:3pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable.

Ciena&#8217;s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena&#8217;s transfer of the products or services to the customer and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold.

Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer.

SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs. </span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.</span></div><div style="text-indent:13.5pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period.

Ciena elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole, and thus the capitalized costs of obtaining a purchase order is applied, even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.</span></div><div style="text-indent:18pt"><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Warranty Accruals</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue.

Historical credit loss experience provides the basis for the estimation of expected credit losses. When assessing for credit losses, Ciena determines collectability by pooling assets with similar characteristics. The allowances for credit losses are each measured on a collective basis when similar risk characteristics exist. The allowances for credit losses are each measured by multiplying the exposure probability of default (the probability that the asset will default within a given time frame) by the loss given default rate (the percentage of the asset not expected to be collected due to default) based on the pool of assets.</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Probability of default rates is published by third-party credit rating agencies.

This hierarchy prioritizes the inputs into three broad levels as follows: </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities; </span></div><div style="padding-left:36pt"><span><br/></span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and</span></div><div style="padding-left:36pt"><span><br/></span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">Level 3 inputs are unobservable inputs based on Ciena&#8217;s assumptions used to measure assets and liabilities at fair value.

A financial asset&#8217;s or liability&#8217;s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Restructuring</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time, Ciena takes actions to align its workforce, facilities, and operating costs with perceived market opportunities, business strategies, and changes in market and business conditions, and to redesign business processes. Ciena recognizes a liability for the cost associated with an exit or disposal activity in the period in which the liability is incurred, except for one-time employee termination benefits related to a service period, typically of more than 60 days, which are accrued over the service period. See Note 4 below.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Foreign Currency</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Certain of Ciena&#8217;s foreign branch offices and subsidiaries use the U.S. Dollar as their functional currency because Ciena Corporation, as the U.S. parent entity, exclusively funds the operations of these branch offices and subsidiaries. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date, and the statement of operations is translated at a monthly average rate. Resulting translation adjustments are recorded directly to a separate component of stockholders&#8217; equity. Where the monetary assets and liabilities are transacted in a currency other than the entity&#8217;s functional currency, re-measurement adjustments are recorded in interest and other income, net on the Consolidated Statements of Operations. See Note 5 below.</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Derivatives</span></div><div><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time, Ciena uses foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less. Ciena also has interest rate swap arrangements to reduce variability in certain forecasted interest expense associated with its term loans. All of these derivatives are designated as cash flow hedges. Ciena also uses foreign currency forward contracts to minimize the effect of foreign exchange rate movements on its net investments in foreign operations. Generally, these derivatives have maturities of 24 months or less. These derivatives are designated as net investment hedges. At the inception of these hedges, and on an ongoing basis, Ciena assesses whether the derivative has been effective in offsetting changes attributable to the hedged risk during the hedging period. The derivative&#8217;s net gain or loss is initially reported as a component of accumulated other comprehensive loss and, upon occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statements of Operations to which the hedged transaction relates. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Ciena records derivative instruments in the Consolidated Statements of Cash Flows within operating, investing, or financing activities consistent with the cash flows of the hedged items.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">From time to time, Ciena uses foreign currency forward contracts to hedge certain balance sheet foreign exchange exposures.

GAAP requires the capitalization of certain software development costs that are incurred subsequent to the date that technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized using the straight-line method over the estimated life of the product. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between Ciena achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant.

On December 30, 2022, Ciena acquired Tibit, a provider and developer of passive optical network (&#8220;PON&#8221;)-specific hardware and operating software that can be integrated into a carrier-grade Ethernet switch and will strengthen Ciena&#8217;s portfolio of next-generation PON solutions that support residential, enterprise, and mobility use cases. These businesses were acquired for an aggregate of approximately $291.7&#160;million, of which $244.7&#160;million was paid in cash, and $47.0&#160;million represents the fair value of Ciena&#8217;s previously held cost method equity investment in Tibit. The acquisition of Tibit triggered the remeasurement of Ciena&#8217;s previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its cost method equity investment of $26.5&#160;million.

During fiscal 2024 and 2023, Ciena recorded $11.7 million and $0.4 million, respectively, in exchange rate losses as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#8217;s functional currency.

The related remeasurement adjustments were recorded in interest and other income, net on the Consolidated Statements of Operations. From time to time, Ciena uses foreign currency forwards to hedge certain of these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net on the Consolidated Statements of Operations. During fiscal 2024, Ciena recorded a gain of $1.4 million from non-hedge designated foreign currency forward contracts. During fiscal 2023 and 2022, Ciena recorded losses of $3.9 million and $4.0&#160;million, respectively, from non-hedge designated foreign currency forward contracts.<span></span>

components that were available, in some cases with expanded lead times, in an effort to prepare Ciena to produce finished goods more quickly upon the easing of supply constraints for certain common

For the periods presented, future demand was calculated using both customer backlog and future forecasted sales. Generally, Ciena&#8217;s customers may cancel or change their orders with limited advance notice, or they may decide not to accept its products and services. Ciena writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena&#8217;s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During fiscal 2024, fiscal 2023 and fiscal 2022, Ciena recorded a provision for excess and obsolescence of $77.3 million, $29.5 million, and $16.2 million, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products primarily sold to communications service providers. Deductions from the provision for excess and obsolete inventory relate primarily to the sale of previously reserved items and disposal activities.</span></div><div

On December 13, 2021, Ciena entered into an accelerated share repurchase agreement (the &#8220;ASR Agreement&#8221;) with Goldman, Sachs &amp; Co. LLC (&#8220;Goldman&#8221;) to repurchase $250.0&#160;million (the &#8220;Repurchase Price&#8221;) of its common stock as part of the repurchase program. Under the terms of the ASR Agreement, Ciena paid the Repurchase Price to Goldman, and received approximately 3.6&#160;million shares of its common stock from Goldman, calculated based on the average of the volume-weighted average prices of Ciena&#8217;s common stock of $69.78 for the period from December 14, 2021 to February 11, 2022, less a discount, which completed the repurchases contemplated by the ASR Agreement. Shares repurchased pursuant to the ASR Agreement were immediately retired upon receipt. During the remainder of fiscal 2022, Ciena repurchased an additional 4.8&#160;million shares of its common stock, for an aggregate purchase price of $250.0&#160;million, at an average price of $51.53 per share. </span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During fiscal 2023, Ciena repurchased an additional 5.7&#160;million shares of its common stock, for an aggregate purchase price of $250.0&#160;million at an average price of $44.08 per share.

Ciena may purchase shares at management&#8217;s discretion in the open market, in privately negotiated transactions, in transactions structured through investment banking institutions, or a combination of the foregoing. Ciena may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares under this authorization. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions.

These factors could result in changes to our contingencies related to positions on prior years&#8217; tax filings. Ciena cannot currently provide an estimate of potential changes.

No additional income tax expense has been provided for any remaining undistributed foreign earnings, or any additional outside basis difference from investments in the foreign subsidiaries, as these amounts continue to be indefinitely reinvested.

All equity awards granted on or after March 23, 2017 are made exclusively from the 2017 Plan. Ciena also makes shares of its common stock available for purchase under the ESPP.

Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2017 Plan, including the number of shares, vesting conditions, and the required service or performance criteria. Options and SARs have a maximum term of ten years, and their exercise price may not be less than 100% of fair market value on the date of grant. Repricing of stock options and SARs is prohibited without stockholder approval. Certain change in control transactions may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the transaction. </span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The 2017 Plan authorizes and reserves 31.2 million shares for issuance.

Ciena&#8217;s outstanding restricted stock unit awards are subject to service-based vesting conditions and/or performance-based vesting conditions. Awards subject to service-based conditions typically vest in increments over a <span style="-sec-ix-hidden:f-1720">three</span> or four-year period. However, the 2017 Plan permits Ciena to grant service-based stock awards with a minimum one-year vesting period. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#8217;s total stockholder return as compared to an index of peer companies, in whole or in part. </span></div><div style="margin-top:6pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During fiscal 2023, Ciena introduced a benefit pursuant to which, upon completion of ten years of service and reaching age 60, executive officers who are residents of the United States, the United Kingdom, or Canada, and who provide 12 months&#8217; notice of their retirement, will receive continued vesting of all of their granted but unvested restricted stock unit (&#8220;RSU&#8221;) awards and a pro-rated amount of their performance stock unit awards and market stock unit awards. Other employees in these and certain other countries will be subject to the same eligibility and notice requirements, but will receive acceleration of their granted but unvested RSU awards upon retirement.

Share-based compensation expense is recognized over the performance period, using graded vesting, which considers each performance period or tranche separately, based on Ciena&#8217;s determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved involves judgment. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation expense is reversed.</span></div><div style="text-indent:18pt"><span><br/></span></div><div style="text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Share-based compensation expense for restricted stock units subject only to service-based vesting conditions and restricted stock units subject to performance-based vesting conditions other than total stockholder return, is recognized only for those awards that ultimately vest.

The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill.

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#8217;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order.

As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena&#8217;s transfer of the products or services to the customer and customer payment for the products or services will be one year or less.

Ciena elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole, and thus the capitalized costs of obtaining a purchase order is applied, even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.</span></div><span></span>

The rules would require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks would also include disclosure of a registrant's greenhouse gas emissions. Finally, the rules would require registrants to present certain climate-related financial metrics in their audited financial statements. On April 12, 2024, the final rules were indefinitely delayed pending the completion of judicial review in consolidated proceedings in the U.S. Court of Appeals, Eighth Circuit.</span></div><span></span>

An operating segment may engage in business activities for which it has yet to earn revenues, for example, start-up operations may be operating segments before earning revenues.</p></div>

The assets acquired, liabilities assumed, contractual contingencies, and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#x2019;s use of the asset and the appropriate discount rates for a market participant. Ciena&#x2019;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Use of Estimates&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The preparation of the financial statements and related disclosures in conformity with Generally Accepted Accounting Principles (&#x201c;GAAP&#x201d;)&#160;requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used for selling prices for multiple element arrangements, shared-based compensation, bad debts, valuation of inventories and investments, recoverability of intangible assets, other long-lived assets and goodwill, income taxes, warranty obligations, restructuring liabilities, derivatives, contingencies and litigation. Ciena bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results may differ materially from management&#x2019;s estimates.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Cash and Cash Equivalents&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Restricted cash collateralizing letters of credit are included in other current assets and other long-term assets, depending on the duration of the restriction.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Investments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s investments in debt securities are classified as available-for-sale and reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#x2019;s cost basis, and Ciena&#x2019;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value. Ciena considers all marketable debt securities that it expects to convert to cash within one year or less to be short-term investments, with all others considered to be long-term investments.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has minority equity investments in privately held technology companies that are classified in other long-term assets. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over the company. Ciena monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of&#160;&lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;November&#160;2, 2024&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;, the combined carrying value of these investments was&#160;$21.7 million. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer. Ciena evaluates these investments for impairment or observable price changes quarterly and records adjustments to interest and other income, net on the Consolidated Statements of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Inventories&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Inventories are stated at the lower of cost or market, with cost computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Ciena records a provision for excess and obsolete inventory when an impairment has been identified.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Segment Reporting&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s chief operating decision maker, its chief executive officer, evaluates the Company&#x2019;s performance and allocates resources based on multiple factors, including measures of segment profit (loss). Operating segments are defined as components of an enterprise that engage in business activities that earn revenue and incur expense, for which discrete financial information is available, and for which such information is evaluated regularly by the chief operating decision maker for purposes of allocating resources and assessing performance. Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. See Note 24 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Goodwill&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year. Ciena also tests goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Annually, Ciena tests goodwill impairment qualitatively, or quantitatively by comparing the fair value of the reporting unit with the unit&#x2019;s carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If Ciena is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Long-lived Assets&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Long-lived assets include equipment, building, furniture and fixtures, operating right-of-use (&#x201c;ROU&#x201d;) assets, finite-lived intangible assets and maintenance spares. Ciena tests long-lived assets for impairment whenever triggering events or changes in circumstances indicate that the asset&#x2019;s carrying amount is not recoverable from its undiscounted cash flows. An impairment loss is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value. Ciena&#x2019;s long-lived assets are assigned to asset groups that represent the lowest level for which cash flows can be identified.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Equipment, Building, Furniture and Fixtures and Internal Use Software&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Equipment, building, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method, generally over useful lives of&#160;three years&#160;to&#160;five years for equipment and furniture and fixtures and the shorter of useful life or lease term for leasehold improvements.&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Qualifying internal use software and website development costs incurred during the application development stage, which consist primarily of outside services and purchased software license costs, are capitalized and amortized straight-line over the estimated useful lives of&#160;two years&#160;to&#160;five years.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Leases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At the inception of a contract, Ciena must determine whether the contract is or contains a lease. The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration. Ciena&#x2019;s evaluation of its contracts follows the assessment of whether there is a right to obtain substantially all of the economic benefits from the use and the right to direct the use of the identified asset in the contract. Operating leases are included in the Operating ROU assets, Operating lease liabilities and Long-term operating lease liabilities on the Consolidated Balance Sheets. Finance leases are included in Equipment, building, furniture and fixtures, net (&#x201c;Finance ROU assets&#x201d;), Accrued liabilities and other short-term obligations and Other long-term obligations on the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has operating and finance leases that primarily relate to real property. Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses, such as common area maintenance and utilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term. Ciena uses discount rates based on incremental borrowing rates, on a collateralized basis, for the respective underlying assets, for terms similar to the respective leases when implicit rates for leases are not determinable. Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method. The amortization and interest expense are recorded separately in the Consolidated Statements of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Intangible Assets&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena records finite-lived intangible assets from acquisitions. Finite-lived intangible assets are carried at cost less accumulated amortization. Amortization is computed using the straight-line method over the expected economic lives of the respective assets, up to seven years, which approximates the use of intangible assets. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Cloud Computing Arrangements&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;     Ciena capitalizes certain costs related to hosting arrangements that are service contracts (cloud computing arrangements). Capitalized costs are included in Other long-term assets on the Consolidated Balance Sheets and are amortized on a straight-line basis over the estimated useful life.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Maintenance Spares&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Maintenance spares are recorded at cost. Ciena depreciates spares ratably over four years. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Concentrations&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Substantially all of Ciena&#x2019;s cash and cash equivalents are maintained at a small number of major U.S. financial institutions. The majority of Ciena&#x2019;s cash equivalents consist of money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits. Because these deposits generally may be redeemed upon demand, management believes that they bear minimal risk.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Historically, a significant percentage of Ciena&#x2019;s revenue has been concentrated among sales to a small number of large communications service providers and cloud providers. Consolidation among Ciena&#x2019;s customers has increased this concentration. Consequently, Ciena&#x2019;s accounts receivable are concentrated among these customers. See Note 2 below. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena&#x2019;s access to certain materials or components is dependent on sole or limited source suppliers. The inability of any of these suppliers to fulfill Ciena&#x2019;s supply requirements, or significant changes in supply cost, could affect future results. Ciena relies on a small number of contract manufacturers to perform the majority of the manufacturing for its products. If Ciena cannot effectively manage these manufacturers or forecast future demand, or if these manufacturers fail to deliver products or components on time, Ciena&#x2019;s business and results of operations may suffer.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Revenue Recognition&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue when control of the promised products or services is transferred to its customer, in an amount that reflects the consideration to which Ciena expects to be entitled in exchange for those products or services.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena determines revenue recognition by applying the following five-step approach:&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;identification of the contract, or contracts, with a customer;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;identification of the performance obligations in the contract;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;determination of the transaction price;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;allocation of the transaction price to the performance obligations in the contract; and&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:32.5pt"&gt;recognition of revenue when, or as, Ciena satisfies a performance obligation.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Generally, Ciena makes sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of Ciena&#x2019;s products and services. These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#x2019;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;software subscription services are invoiced quarterly or annually in advance of the service term. Ciena&#x2019;s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena&#x2019;s transfer of the products or services to the customer and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services, such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Significant Judgments &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is allocated among performance obligations based on standalone selling price (&#x201c;SSP&#x201d;). SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Capitalized Contract Acquisition Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena capitalizes and amortizes incremental costs of obtaining a contract considering each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole, and thus the capitalized costs of obtaining a purchase order is applied, even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Warranty Accruals&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue. Estimated warranty costs include estimates for material costs, technical support labor costs and associated overhead. Warranty is included in cost of goods sold and is determined based on actual warranty cost experience, estimates of component failure rates and management&#x2019;s industry experience. Ciena&#x2019;s sales contracts do not permit the right of return of the product by the customer after the product has been accepted.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Allowance for Credit Losses for Accounts Receivable and Contract Assets&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena estimates its allowances for credit losses using relevant available information from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. When assessing for credit losses, Ciena determines collectability by pooling assets with similar characteristics. The allowances for credit losses are each measured on a collective basis when similar risk characteristics exist. The allowances for credit losses are each measured by multiplying the exposure probability of default (the probability that the asset will default within a given time frame) by the loss given default rate (the percentage of the asset not expected to be collected due to default) based on the pool of assets.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Probability of default rates is published by third-party credit rating agencies. Adjustments to Ciena&#x2019;s exposure probability may take into account a number of factors, including, but not limited to, various customer-specific factors, the potential sovereign risk of the geographic locations in which the customer is operating, and macroeconomic conditions. These factors are updated regularly or when facts and circumstances indicate that an update is deemed necessary. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Accounts Receivable Factoring &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has entered into factoring agreements to sell certain receivables to unrelated third-party financial institution on a non-recourse basis. These transactions result in a reduction in accounts receivable because the agreements transfer effective control over, and risk related to, the receivables to the buyers. Ciena's factoring agreements do not allow for recourse in the event of uncollectability, and Ciena does not retain any interest in the underlying accounts receivable once sold. Trade accounts receivables balances sold are removed from the consolidated balance sheets and cash received is reflected as cash provided by (used in) operating activities in the Consolidated Statements of Cash Flow. Factoring related interest expense is recorded to interest and other income, net on the Consolidated Statements of Operations. See Note 8 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:15.75pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Research and Development&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena charges all research and development costs to expense as incurred. Types of expense incurred in research and development include employee compensation, prototype equipment, consulting and third-party services, depreciation, facility costs and information technology.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Government Grants&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Consolidated Statement of Operations to which the grant activity relates. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Advertising Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena expenses all advertising costs as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Legal Costs&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena expenses legal costs associated with litigation as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Share-Based Compensation Expense&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena measures and recognizes compensation expense for share-based awards and employee stock purchases related to its Amended and Restated 2003 Employee Stock Purchase Plan (the &#x201c;ESPP&#x201d;) based on estimated fair values on the date of grant. Ciena estimates the fair value of employee stock purchases related to the ESPP using the Black-Scholes option-pricing model. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense for service-based restricted stock unit awards is recognized ratably over the vesting period on a straight-line basis in the Consolidated Statements of Operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; Awards with performance-based vesting conditions: (i) require the achievement of certain operational, financial or other performance criteria or targets; or (ii) vest based on Ciena&#x2019;s total stockholder return as compared to an index of peer companies, in whole or in part. Ciena estimates the fair value of restricted stock units subject to performance-based vesting conditions, other than total stockholder return, by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense, for performance-based restricted stock units other than total stockholder return, is recognized over the performance period, using graded vesting, which considers each performance period or tranche separately, based on Ciena&#x2019;s determination of whether it is probable that the performance targets will be achieved and is included in the Consolidated Statements of Operations. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based compensation expense for restricted stock units subject only to service-based vesting conditions and restricted stock units subject to performance-based vesting conditions other than total stockholder return, is recognized only for those awards that ultimately vest. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena estimates the fair value of performance based awards subject to total stockholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant and recognizes the related share-based compensation expense over the performance period. Ciena reverses share-based compensation expense on performance based awards subject to total stockholder return only when the requisite service period is not reached. See Note 23 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Stock Repurchase Program&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Shares repurchased pursuant to Ciena&#x2019;s stock repurchase program are immediately retired upon purchase. Repurchased common stock is reflected as a reduction of stockholders&#x2019; equity. Ciena&#x2019;s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its stock repurchase programs, Ciena has had an accumulated deficit balance, therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Income Taxes&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena accounts for income taxes using an asset and liability approach. This approach recognizes deferred tax assets and liabilities (&#x201c;DTA&#x201d;) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena&#x2019;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2020 through 2023, in Canada for 2014, and in the United Kingdom for 2016 through 2022. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#x2019;s consolidated financial position, results of operations or cash flows. Ciena&#x2019;s major tax jurisdictions and the earliest open tax years are as follows: United States (2021), United Kingdom (2016), Canada (2014), and India (2020). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards. Ciena classifies interest and penalties related to uncertain tax positions as a component of income tax expense.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;Ciena is required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena is electing to use the period cost method for future global intangible low-taxed income (&#x201c;GILTI&#x201d;) inclusions. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Loss Contingencies&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena is subject to the possibility of various losses arising in the ordinary course of business. These may relate to disputes, litigation and other legal actions. Ciena considers the likelihood of loss or the incurrence of a liability, as well as Ciena&#x2019;s ability to estimate the amount of loss reasonably, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Ciena regularly evaluates current information available to it in order to determine whether any accruals should be adjusted and whether new accruals are required.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Fair Value of Financial Instruments&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The carrying value of Ciena&#x2019;s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair market value due to the relatively short period of time to maturity. For information related to the fair value of Ciena&#x2019;s short-term and long-term debt, see Note 18 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Fair value for the measurement of financial assets and liabilities is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Ciena utilizes a valuation hierarchy for disclosure of the inputs for fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities; &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;Level 3 inputs are unobservable inputs based on Ciena&#x2019;s assumptions used to measure assets and liabilities at fair value. The fair values are determined based on model-based techniques using inputs Ciena could not corroborated with market data.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;By distinguishing between inputs that are observable in the marketplace, and therefore more objective, and those that are unobservable, and therefore more subjective, the hierarchy is designed to indicate the relative reliability of the fair value measurements. A financial asset&#x2019;s or liability&#x2019;s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Restructuring&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena takes actions to align its workforce, facilities, and operating costs with perceived market opportunities, business strategies, and changes in market and business conditions, and to redesign business processes. Ciena recognizes a liability for the cost associated with an exit or disposal activity in the period in which the liability is incurred, except for one-time employee termination benefits related to a service period, typically of more than 60 days, which are accrued over the service period. See Note 4 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Foreign Currency&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Certain of Ciena&#x2019;s foreign branch offices and subsidiaries use the U.S. Dollar as their functional currency because Ciena Corporation, as the U.S. parent entity, exclusively funds the operations of these branch offices and subsidiaries. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date, and the statement of operations is translated at a monthly average rate. Resulting translation adjustments are recorded directly to a separate component of stockholders&#x2019; equity. Where the monetary assets and liabilities are transacted in a currency other than the entity&#x2019;s functional currency, re-measurement adjustments are recorded in interest and other income, net on the Consolidated Statements of Operations. See Note 5 below.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Derivatives&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena uses foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less. Ciena also has interest rate swap arrangements to reduce variability in certain forecasted interest expense associated with its term loans. All of these derivatives are designated as cash flow hedges. Ciena also uses foreign currency forward contracts to minimize the effect of foreign exchange rate movements on its net investments in foreign operations. Generally, these derivatives have maturities of 24 months or less. These derivatives are designated as net investment hedges. At the inception of these hedges, and on an ongoing basis, Ciena assesses whether the derivative has been effective in offsetting changes attributable to the hedged risk during the hedging period. The derivative&#x2019;s net gain or loss is initially reported as a component of accumulated other comprehensive loss and, upon occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statements of Operations to which the hedged transaction relates. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena records derivative instruments in the Consolidated Statements of Cash Flows within operating, investing, or financing activities consistent with the cash flows of the hedged items.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time, Ciena uses foreign currency forward contracts to hedge certain balance sheet foreign exchange exposures. These forward contracts are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net on the Consolidated Statements of Operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;See Notes 7 and 15 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Computation of Net Income per Share &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena calculates basic net income per common share (&#x201c;Basic EPS&#x201d;) by dividing earnings attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income per potential common share (&#x201c;Diluted EPS&#x201d;) includes other potential dilutive shares that would be outstanding if securities or other contracts to issue common stock were exercised or converted into common stock. Ciena uses a dual presentation of Basic EPS and Diluted EPS on the face of its income statement. A reconciliation of the numerator and denominator used for the Basic EPS and Diluted EPS computations is set forth in Note 20 below.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Software Development Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena develops software for sale to its customers. GAAP requires the capitalization of certain software development costs that are incurred subsequent to the date that technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized using the straight-line method over the estimated life of the product. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between Ciena achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant. Accordingly, Ciena has not capitalized any software development costs.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Newly Issued Accounting Standards - Effective&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;In October 2021, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2021-08 (&#x201c;ASU 2021-08&#x201d;), &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"&gt;Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; to improve the accounting for acquired revenue contracts with customers in a business combination to address recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer.

The assets acquired, liabilities assumed, contractual contingencies, and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant&#x2019;s use of the asset and the appropriate discount rates for a market participant. Ciena&#x2019;s estimates are based on historical experience, information obtained from the management of the acquired companies and, when &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;</us-gaap:BusinessCombinationsPolicy>

Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena&#x2019;s cost basis, and Ciena&#x2019;s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value.

Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year. Ciena also tests goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Annually, Ciena tests goodwill impairment qualitatively, or quantitatively by comparing the fair value of the reporting unit with the unit&#x2019;s carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If Ciena is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.&lt;/span&gt;&lt;/div&gt;</us-gaap:GoodwillAndIntangibleAssetsGoodwillPolicy>

The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration. Ciena&#x2019;s evaluation of its contracts follows the assessment of whether there is a right to obtain substantially all of the economic benefits from the use and the right to direct the use of the identified asset in the contract. Operating leases are included in the Operating ROU assets, Operating lease liabilities and Long-term operating lease liabilities on the Consolidated Balance Sheets. Finance leases are included in Equipment, building, furniture and fixtures, net (&#x201c;Finance ROU assets&#x201d;), Accrued liabilities and other short-term obligations and Other long-term obligations on the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena has operating and finance leases that primarily relate to real property. Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses, such as common area maintenance and utilities.&lt;/span&gt;&lt;/div&gt;Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term. Ciena uses discount rates based on incremental borrowing rates, on a collateralized basis, for the respective underlying assets, for terms similar to the respective leases when implicit rates for leases are not determinable. Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method. The amortization and interest expense are recorded separately in the Consolidated Statements of Operations.</us-gaap:LesseeLeasesPolicyTextBlock>

These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena&#x2019;s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;software subscription services are invoiced quarterly or annually in advance of the service term. Ciena&#x2019;s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena&#x2019;s transfer of the products or services to the customer and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services, such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Significant Judgments &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is allocated among performance obligations based on standalone selling price (&#x201c;SSP&#x201d;). SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Capitalized Contract Acquisition Costs&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:13.5pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena capitalizes and amortizes incremental costs of obtaining a contract considering each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole, and thus the capitalized costs of obtaining a purchase order is applied, even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Historical credit loss experience provides the basis for the estimation of expected credit losses. When assessing for credit losses, Ciena determines collectability by pooling assets with similar characteristics. The allowances for credit losses are each measured on a collective basis when similar risk characteristics exist. The allowances for credit losses are each measured by multiplying the exposure probability of default (the probability that the asset will default within a given time frame) by the loss given default rate (the percentage of the asset not expected to be collected due to default) based on the pool of assets.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Probability of default rates is published by third-party credit rating agencies. Adjustments to Ciena&#x2019;s exposure probability may take into account a number of factors, including, but not limited to, various customer-specific factors, the potential sovereign risk of the geographic locations in which the customer is operating, and macroeconomic conditions. These factors are updated regularly or when facts and circumstances indicate that an update is deemed necessary. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Accounts Receivable Factoring &lt;/span&gt;&lt;/div&gt;Ciena has entered into factoring agreements to sell certain receivables to unrelated third-party financial institution on a non-recourse basis. These transactions result in a reduction in accounts receivable because the agreements transfer effective control over, and risk related to, the receivables to the buyers. Ciena's factoring agreements do not allow for recourse in the event of uncollectability, and Ciena does not retain any interest in the underlying accounts receivable once sold. Trade accounts receivables balances sold are removed from the consolidated balance sheets and cash received is reflected as cash provided by (used in) operating activities in the Consolidated Statements of Cash Flow. Factoring related interest expense is recorded to interest and other income, net on the Consolidated Statements of Operations.</cien:CreditLossAccountsReceivableAndContractAssetsPolicyPolicyTextBlock>

Ciena estimates the fair value of employee stock purchases related to the ESPP using the Black-Scholes option-pricing model. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense for service-based restricted stock unit awards is recognized ratably over the vesting period on a straight-line basis in the Consolidated Statements of Operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; Awards with performance-based vesting conditions: (i) require the achievement of certain operational, financial or other performance criteria or targets; or (ii) vest based on Ciena&#x2019;s total stockholder return as compared to an index of peer companies, in whole or in part. Ciena estimates the fair value of restricted stock units subject to performance-based vesting conditions, other than total stockholder return, by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense, for performance-based restricted stock units other than total stockholder return, is recognized over the performance period, using graded vesting, which considers each performance period or tranche separately, based on Ciena&#x2019;s determination of whether it is probable that the performance targets will be achieved and is included in the Consolidated Statements of Operations. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based compensation expense for restricted stock units subject only to service-based vesting conditions and restricted stock units subject to performance-based vesting conditions other than total stockholder return, is recognized only for those awards that ultimately vest. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. &lt;/span&gt;&lt;/div&gt;Ciena estimates the fair value of performance based awards subject to total stockholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant and recognizes the related share-based compensation expense over the performance period. Ciena reverses share-based compensation expense on performance based awards subject to total stockholder return only when the requisite service period is not reached.</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Repurchased common stock is reflected as a reduction of stockholders&#x2019; equity. Ciena&#x2019;s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its stock repurchase programs, Ciena has had an accumulated deficit balance, therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.&lt;/span&gt;&lt;/div&gt;</us-gaap:StockholdersEquityPolicyTextBlock>

This approach recognizes deferred tax assets and liabilities (&#x201c;DTA&#x201d;) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena&#x2019;s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2020 through 2023, in Canada for 2014, and in the United Kingdom for 2016 through 2022. Management does not expect the outcome of these audits to have a material adverse effect on Ciena&#x2019;s consolidated financial position, results of operations or cash flows. Ciena&#x2019;s major tax jurisdictions and the earliest open tax years are as follows: United States (2021), United Kingdom (2016), Canada (2014), and India (2020). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards. Ciena classifies interest and penalties related to uncertain tax positions as a component of income tax expense.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;Ciena is required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled. &lt;/span&gt;&lt;/div&gt;Ciena is electing to use the period cost method for future global intangible low-taxed income (&#x201c;GILTI&#x201d;) inclusions.</us-gaap:IncomeTaxPolicyTextBlock>

These may relate to disputes, litigation and other legal actions. Ciena considers the likelihood of loss or the incurrence of a liability, as well as Ciena&#x2019;s ability to estimate the amount of loss reasonably, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated.

As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

Generally, these derivatives have maturities of 24 months or less. Ciena also has interest rate swap arrangements to reduce variability in certain forecasted interest expense associated with its term loans.

The rules would require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks would also include disclosure of a registrant's greenhouse gas emissions. Finally, the rules would require registrants to present certain climate-related financial metrics in their audited financial statements. On April 12, 2024, the final rules were indefinitely delayed pending the completion of judicial review in consolidated proceedings in the U.S. Court of Appeals, Eighth Circuit.&lt;/span&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

On December 30, 2022, Ciena acquired Tibit, a provider and developer of passive optical network (&#x201c;PON&#x201d;)-specific hardware and operating software that can be integrated into a carrier-grade Ethernet switch and will strengthen Ciena&#x2019;s portfolio of next-generation PON solutions that support residential, enterprise, and mobility use cases. These businesses were acquired for an aggregate of approximately $291.7&#160;million, of which $244.7&#160;million was paid in cash, and $47.0&#160;million represents the fair value of Ciena&#x2019;s previously held cost method equity investment in Tibit. The acquisition of Tibit triggered the remeasurement of Ciena&#x2019;s previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its cost method equity investment of $26.5&#160;million. Each of these transactions has been accounted for as the acquisition of a business. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena incurred approximately $3.4&#160;million in acquisition-related costs associated with these acquisitions. These costs and expenses primarily include fees associated with financial, legal, and accounting advisors and employment-related costs. These costs were recorded in acquisition and integration costs on the Consolidated Statements of Operations.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span

investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its equity investment of $26.5&#160;million. See Note 3 above. During fiscal 2022, Ciena recorded a net gain of $4.1&#160;million on its equity investments.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena Corporation, as the U.S. parent entity, uses the U.S. Dollar as its functional currency; however, some of its foreign branch offices and subsidiaries use the local currency as their functional currency. During fiscal 2024 and 2023, Ciena recorded $11.7 million and $0.4 million, respectively, in exchange rate losses as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#x2019;s functional currency. During fiscal 2022, Ciena recorded $2.5 million in exchange &lt;/span&gt;&lt;/div&gt;rate gains as a result of monetary assets and liabilities that were transacted in a currency other than the entity&#x2019;s functional currency. The related remeasurement adjustments were recorded in interest and other income, net on the Consolidated Statements of Operations. From time to time, Ciena uses foreign currency forwards to hedge certain of these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net on the Consolidated Statements of Operations. During fiscal 2024, Ciena recorded a gain of $1.4 million from non-hedge designated foreign currency forward contracts. During fiscal 2023 and 2022, Ciena recorded losses of $3.9 million and $4.0&#160;million, respectively, from non-hedge designated foreign currency forward contracts.</us-gaap:OtherNonoperatingIncomeAndExpenseTextBlock>

manufacturing capacity and accumulating raw materials inventory of components that were available, in some cases with expanded lead times, in an effort to prepare Ciena to produce finished goods more quickly upon the easing of supply constraints for certain common components. During fiscal 2024 Ciena reduced its raw materials inventory of components primarily due to the consumption of raw materials previously purchased. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:13.5pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena makes estimates about future customer demand for its products when establishing the appropriate reserve for excess and obsolete inventory. For the periods presented, future demand was calculated using both customer backlog and future forecasted sales. Generally, Ciena&#x2019;s customers may cancel or change their orders with limited advance notice, or they may decide not to accept its products and services. Ciena writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena&#x2019;s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During fiscal 2024, fiscal 2023 and fiscal 2022, Ciena recorded a provision for excess and obsolescence of $77.3 million, $29.5 million, and $16.2 million, respectively, primarily related to a decrease in the forecasted demand for certain Networking Platforms products primarily sold to communications service providers. Deductions from the provision for excess and obsolete inventory relate primarily to the sale of previously reserved items and disposal activities.&lt;/span&gt;&lt;/div&gt;&lt;div

On December 13, 2021, Ciena entered into an accelerated share repurchase agreement (the &#x201c;ASR Agreement&#x201d;) with Goldman, Sachs &amp;amp; Co. LLC (&#x201c;Goldman&#x201d;) to repurchase $250.0&#160;million (the &#x201c;Repurchase Price&#x201d;) of its common stock as part of the repurchase program. Under the terms of the ASR Agreement, Ciena paid the Repurchase Price to Goldman, and received approximately 3.6&#160;million shares of its common stock from Goldman, calculated based on the average of the volume-weighted average prices of Ciena&#x2019;s common stock of $69.78 for the period from December 14, 2021 to February 11, 2022, less a discount, which completed the repurchases contemplated by the ASR Agreement. Shares repurchased pursuant to the ASR Agreement were immediately retired upon receipt. During the remainder of fiscal 2022, Ciena repurchased an additional 4.8&#160;million shares of its common stock, for an aggregate purchase price of $250.0&#160;million, at an average price of $51.53 per share. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;During fiscal 2023, Ciena repurchased an additional 5.7&#160;million shares of its common stock, for an aggregate purchase price of $250.0&#160;million at an average price of $44.08 per share. During fiscal 2024, Ciena repurchased an additional 4.5&#160;million shares of its common stock, for an aggregate purchase price of $250.0&#160;million at an average price of $55.07 per share, which completed the authorized repurchases contemplated under the program.

Ciena may purchase shares at management&#x2019;s discretion in the open market, in privately negotiated transactions, in transactions structured through investment banking institutions, or a combination of the foregoing. Ciena may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares under this authorization. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions. The program may be modified, suspended or discontinued at any time.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The purchase price for the shares of Ciena&#x2019;s stock repurchased is reflected as a reduction of common stock and additional paid-in capital.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3.84pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:3.84pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Impact of Inflation Reduction Act 1% Excise Tax on Share Repurchases&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Beginning fiscal 2023, a 1% excise tax on the market value of shares repurchased offset by 1% of the market value of shares issued was implemented.

If recognized, the entire balance of unrecognized tax benefits would impact the effective tax rate. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;Changes in tax laws, regulations, administrative practices, and interpretations may impact Ciena&#x2019;s tax contingencies. Due to various factors, the amounts ultimately paid, if any, upon the resolution of the issues raised by the taxing authorities may differ from the amounts accrued. It is reasonably possible that within the next twelve months Ciena will receive additional assessments by various tax authorities or possibly reach resolution of income tax controversies in one or more various jurisdictions. These factors could result in changes to our contingencies related to positions on prior years&#x2019; tax filings. Ciena cannot currently provide an estimate of potential changes. As statutes of limitation expire, unrecognized tax benefits including interest and penalties related to contingencies may be reversed, resulting in an income tax benefit. Over the next twelve months, &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;Ciena estimates that statutes on approximately $26.4&#160;million of unrecognized tax benefits may expire, which would result in a net tax benefit. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;As of &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;November&#160;2, 2024&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;, we have approximately $93.0&#160;million of undistributed earnings at our foreign subsidiaries that we identified in fiscal 2023 as no longer indefinitely reinvested and $1.5&#160;million of deferred tax liability remaining on Ciena&#x2019;s Consolidated Balance sheets for the income tax effects related to the future repatriation of these earnings. No additional income tax expense has been provided for any remaining undistributed foreign earnings, or any additional outside basis difference from investments in the foreign subsidiaries, as these amounts continue to be indefinitely reinvested. If remaining undistributed foreign earnings and profits of $415.0&#160;million were repatriated to the U.S., the provisional amount of unrecognized deferred tax liability, which is primarily related to foreign withholding taxes, is an estimated $34.0&#160;million; however, the amount may be lower depending on Ciena&#x2019;s ability to utilize tax credits associated with the distribution. Additionally, there are no other significant temporary differences for which a deferred tax liability or asset is not being recognized.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;As of &lt;/span&gt;&lt;span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;November&#160;2, 2024&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%"&gt;, Ciena continues to maintain a valuation allowance of $192.4&#160;million against its gross deferred tax assets primarily.

Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2017 Plan, including the number of shares, vesting conditions, and the required service or performance criteria. Options and SARs have a maximum term of ten years, and their exercise price may not be less than 100% of fair market value on the date of grant. Repricing of stock options and SARs is prohibited without stockholder approval. Certain change in control transactions may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the transaction. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The 2017 Plan authorizes and reserves 31.2 million shares for issuance. The number of shares available under the 2017 Plan is also increased from time to time by: (i)&#160;the number of shares subject to outstanding awards granted under Ciena&#x2019;s prior equity compensation plans that are forfeited, expire or are canceled without delivery of common stock following the effective date of the 2017 Plan, and (ii)&#160;the number of shares subject to awards assumed or substituted in connection with the acquisition &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;of another company.

Ciena&#x2019;s outstanding restricted stock unit awards are subject to service-based vesting conditions and/or performance-based vesting conditions. Awards subject to service-based conditions typically vest in increments over a &lt;span style="-sec-ix-hidden:f-1720"&gt;three&lt;/span&gt; or four-year period. However, the 2017 Plan permits Ciena to grant service-based stock awards with a minimum one-year vesting period. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena&#x2019;s total stockholder return as compared to an index of peer companies, in whole or in part. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;During fiscal 2023, Ciena introduced a benefit pursuant to which, upon completion of ten years of service and reaching age 60, executive officers who are residents of the United States, the United Kingdom, or Canada, and who provide 12 months&#x2019; notice of their retirement, will receive continued vesting of all of their granted but unvested restricted stock unit (&#x201c;RSU&#x201d;) awards and a pro-rated amount of their performance stock unit awards and market stock unit awards. Other employees in these and certain other countries will be subject to the same eligibility and notice requirements, but will receive acceleration of their granted but unvested RSU awards upon retirement. This program accelerates the recognition of share-based compensation expense. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Assumptions for Restricted Stock Unit Awards&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Share-based expense for service-based restricted stock unit awards is recognized ratably over the vesting period on a straight-line basis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total stockholder return, by assuming the satisfaction of any performance-based objectives at the &#x201c;target&#x201d; level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense is recognized over the performance period, using graded vesting, which considers each performance period or tranche separately, based on Ciena&#x2019;s determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved involves judgment. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation expense is reversed.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Share-based compensation expense for restricted stock units subject only to service-based vesting conditions and restricted stock units subject to performance-based vesting conditions other than total stockholder return, is recognized only for those awards that ultimately vest. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. Reversal of share-based compensation expense based on forfeitures can materially affect the measurement of estimated fair value of Ciena&#x2019;s share-based compensation.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Ciena estimates the fair value of performance based awards subject to total stockholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model. Ciena reverses share-based compensation expense on performance based awards subject to total stockholder return only when the requisite service period is not reached. Assumptions for awards granted during fiscal 2024, fiscal 2023 and fiscal 2022 included the following:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:11pt;text-align:center"&gt;&lt;table
