We contract with a number of large OEM and end-user service providers and product companies that have considerable bargaining power, which may require us to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.
Large OEM and end-user service providers and product companies comprise a significant portion of our customer base. These customers generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers, including us. As we seek to expand our sales to existing customers and acquire new customers, we may be required to agree to terms and conditions that are favorable to our customers and that may affect the timing of our ability to recognize revenue, increase our costs and have an adverse effect on our business, financial condition, and results of operations. Furthermore, large customers have increased buying power and ability to require onerous terms in our contracts with them, including pricing, warranties, and indemnification terms. If we are unable to satisfy the terms of these contracts, it could result in liabilities of a material nature, including litigation, damages, additional costs, loss of market share and loss of reputation. Additionally, the terms these large customers require, such as most-favored nation or exclusivity provisions, may impact our ability to do business with other customers and generate revenues from such customers.
Our products may contain defects that could cause us to incur significant costs, divert our attention from product development efforts and result in loss of customers.
Our products are complex, and defects and quality issues are found from time-to-time. Networking products in particular frequently contain undetected software or hardware defects when first introduced or as new versions are released. In addition, our products are often embedded in or deployed in conjunction with our customers’ products which incorporate a variety of components produced by third parties, which may contain defects. As a result, when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages or warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and manufacturing resources, and cause significant customer relation problems or loss of customers, or risk exposure to product liability suits, all of which would harm our business. Additionally, changes in our or our suppliers' manufacturing processes or the inadvertent use of defective materials by us or our suppliers could result in an adverse effect on our ability to achieve acceptable manufacturing yields and product reliability. To the extent that we do not achieve and maintain our projected yields or product reliability, our business, operating results, financial condition and customer relationships would be adversely affected.
We face a number of risks related to pursuing strategic transactions.
We have in the past and expect to continue to seek to expand and diversify our operations with additional acquisitions and strategic transactions as well as acquisitions of complementary technologies, products, assets and businesses. We may be unable to identify or complete prospective acquisitions for many reasons, including competition from other potential acquirers, the effects of consolidation in our industries and potentially high valuations of acquisition candidates. Even if we do identify acquisitions or enter into agreements with respect to such acquisitions, we may not be able to complete the acquisition due to regulatory requirements or restrictions, competition, or other reasons. In addition, applicable antitrust laws and other regulations may limit our ability to acquire targets or force us to divest all or a portion of our business or an acquired business. If we are unable to identify suitable targets or complete acquisitions, our growth prospects may suffer, and we may not be able to realize sufficient scale and technological advantages to compete effectively in all markets.
In connection with acquisitions, risks to us and our business include:
• diversion of management’s attention from normal daily operations of the business;     
• unforeseen expenses, delays or conditions imposed on the acquisition or transaction, including due to required regulatory approvals or consents, or fees that may be triggered upon a failure to consummate an acquisition or transaction for certain reasons;
• the inability to retain and obtain required regulatory approvals, licenses and permits;
• loss of employees, customers, suppliers or partners due to uncertainty of a transaction; and
• failure to consummate an acquisition resulting in negative publicity and/or negative impression of us in the investment community that could impact our stock price.
85

We have also faced litigation in connection with acquisitions, some of which continues following the consummation of the acquisition. Such litigation may be costly and diverts management time and attention.
We have in the past, and may in the future, divest or reduce our investment in certain businesses or product lines from time-to-time. Such divestitures involve risks, such as difficulty separating portions from our other businesses, distracting employees, incurring potential loss of revenue, negatively impacting margins, and potentially disrupting customer relationships. We may also incur significant costs associated with exit or disposal activities, related impairment charges, or both.
If we are unable to successfully manage any of these risks in relation to any future acquisitions or divestitures, our business, financial condition and results of operations could be adversely impacted.
We may be unable to successfully implement our acquisitions strategy or integrate acquired companies and personnel with existing operations.
To the extent we are successful in making acquisitions, such as our acquisitions of Cloud Light, NeoPhotonics and the IPG telecom transmission product lines, we may be unsuccessful in implementing our acquisitions strategy, or integrating acquired companies, businesses or product lines and personnel with existing operations, the integration may be more difficult or more costly than anticipated, or the transaction may not further our business strategy as we expected or we may overpay for, or otherwise not realize the expected return on, our investment. Some of the challenges involved integrating businesses and acquisitions include:
• difficulty preserving relationships with customers, suppliers or partners;
• potential difficulties in completing projects associated with in-process R&D;
• unanticipated liabilities or our exposure for known contingencies and liabilities may exceed our estimates;
• insufficient net revenue or unexpected expenses that negatively impact our margins and profitability;
• unexpected losses of key employees of the acquired company, inability to attract, recruit, retain, and motivate current and prospective employees or inability to maintain our company culture;
• unexpected expenses for cost of litigation or other legal proceedings related to the acquisition or the acquired company;
• conforming the acquired company’s standards, processes, procedures and controls with our operations, including integrating Enterprise Resource Planning (“ERP”) systems and other key business applications;
• coordinating new product and process development;
• increasing complexity from combining operations, including administrative functions, finance and human resources;
• increasing the scope, geographic diversity and complexity of our operations;
• difficulties in integrating operations across different cultures and languages and to address the particular economic, currency, political, and regulatory risks associated with specific countries;
• difficulties in integrating acquired technology;
• difficulties in coordinating and integrating geographically separated personnel, organizations, systems and facilities;
• difficulty managing customer transitions or entering into new markets;
• difficulties in consolidating facilities and transferring processes and know-how;
• diversion of management’s attention from other business concerns;
• temporary loss of productivity or operational efficiency;
• dilution of our current stockholders as a result of any issuance of equity securities as acquisition consideration;
86

• adverse tax or accounting impact;
• expenditure of cash that would otherwise be available to operate our business; and
• indebtedness on terms that are unfavorable to us, limit our operational flexibility or that we are unable to repay.
In addition, following an acquisition, we may have difficulty forecasting the financial results of the combined company and the market price of our common stock could be adversely affected if the effect of any acquisitions on our consolidated financial results is dilutive or is below the market's or financial analysts' expectations, or if there are unanticipated changes in the business or financial performance of the target company or the combined company. Any failure to successfully integrate acquired businesses may disrupt our business and adversely impact our business, financial condition and results of operations.
Restructuring activities could disrupt our business and affect our results of operations.
We have taken steps, including implementing reductions in force and internal reorganizations, to reduce the cost of our operations, improve efficiencies, or realign our organization and staffing to better match our market opportunities and our technology development initiatives. We may take similar steps in the future as we seek to realize operating synergies, to achieve our target operating model and profitability objectives, or to reflect more closely changes in the strategic direction of our business or the evolution of our site strategy and workplace. These changes could be disruptive to our business, including our research and development efforts, and may result in the recording of special charges, including workforce reduction or restructuring costs. 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 .
We may not be able to realize tax savings from our international structure, which could adversely affect our operating results.
During fiscal years 2023 and 2025, the Company completed international restructurings that included the intra-entity transfer of certain intellectual property and other assets used in the business among various subsidiaries. The structures implemented may be challenged by tax authorities, and if such challenges are successful, the tax consequence we expect to realize could be adversely impacted. If substantial modifications to our international structure or the way we operate our business are made, such as if future acquisitions or divestitures occur, if we or our customers or suppliers change our logistics, if changes in domestic and international tax laws negatively impact the structure, if we do not operate our business consistent with the structure and applicable tax provisions, if we fail to achieve our revenue and profit goals, or if the international structure or our application of arm’s-length principles to intercompany arrangements is successfully challenged by the U.S. or foreign tax authorities, our effective tax rate may increase, which could have an adverse effect on our operating and financial results.
Changes in tax laws could have an adverse effect on our business, cash flow, results of operations or financial conditions.
As a multinational corporation, we are subject to income taxes as well as non-income based taxes, in both the U.S. and various foreign jurisdictions. Significant uncertainties exist with respect to the amount of our tax liabilities, including those arising from potential changes in laws in the countries in which we do business and the possibility of adverse determinations with respect to the application of existing laws. Many judgments are required in determining our worldwide provision for income taxes and other tax liabilities, and we are under audit by various tax authorities, which often do not agree with positions taken by us on our tax returns. Any unfavorable resolution of these uncertainties may have a significant adverse impact on our tax rate.
The Organization for Economic Cooperation and Development (the “OECD”) has proposed changes to existing tax laws, including a proposed global minimum tax of 15%, also known as Pillar Two. Many countries, including European Union member states have adopted or are considering adopting legislation to enact these proposals. The OECD and participating jurisdictions have recently agreed to a “side-by-side” solution that exempts U.S.-parented multinational businesses, like us, from certain provisions of Pillar Two for fiscal years beginning on or after January 1, 2026. Any of these developments or changes in federal, state, or international tax laws or tax rulings could adversely affect our effective tax rate and our operating results. There can be no assurance that our effective tax rates, tax payments, or incentives will not be adversely affected by these or other developments or changes in law.
87

On July 4, 2025, H.R.1, the One Big Beautiful Bill Act (“OBBBA”), was signed into law which contains a broad range of provisions affecting businesses including permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. We have evaluated these changes during the three and nine months ended March 28, 2026 and believe the impact to our tax provision during these periods is not material.
Other countries also continue to enact and consider enacting new laws, which could increase our tax obligations, cause us to change the way we do business or our operations or otherwise adversely affect us. The foregoing items could increase our future tax expense, could change our future intentions regarding reinvestment of foreign earnings, and could have an adverse effect on our business, financial condition and results of operations.
We are also subject to the continuous examination of our income tax and other returns by the Internal Revenue Service and other tax authorities globally, and we have a number of such reviews underway at any time. It is possible that tax authorities may disagree with certain positions we have taken, and an adverse outcome of such a review or audit could have a negative effect on our financial position and operating results. There can be no assurance that the outcomes from such examinations, or changes in tax law or regulation impacting our effective tax rates, will not have an adverse effect on our business, financial condition and results of operations.
Our operating results may be subject to volatility due to fluctuations in foreign currency.
We are exposed to foreign exchange risks with regard to our international operations which may affect our operating results. Since we conduct business in currencies other than U.S. dollars but report our financial results in U.S. dollars, we face exposure to fluctuations in currency exchange rates. Due to these fluctuations, operating results may differ materially from expectations, and we may record significant gains or losses on the remeasurement of intercompany balances. Although we price our products primarily in U.S. dollars, a portion of our operating expenses are incurred in foreign currencies. For example, a portion of our expenses are denominated in the U.K. pound sterling, Chinese yuan and Thai baht. In addition, we also have term loans denominated in Japanese Yen. Fluctuations in the exchange rate between these currencies and other currencies in which we collect revenues and/or pay expenses could have a material effect on our future operating results. Recently, our exposure to foreign currencies has increased as our non-U.S. manufacturing footprint has expanded. We continue to look for opportunities to leverage the lower cost of non-U.S. manufacturing, including the United Kingdom, China, Thailand, and Japan. While these geographies are lower cost than the U.S. and such concentration will in general lower our total cost to manufacture, this increase in concentration in non-U.S. manufacturing will also increase the volatility of our results. If the value of the U.S. dollar depreciates relative to certain other foreign currencies, it would increase our costs including the cost of local operating expenses and procurement of materials or services that we purchase in foreign currencies, as expressed in U.S. dollars. Conversely, if the U.S. dollar strengthens relative to other currencies, such strengthening could raise the relative cost of our products to non-U.S. customers, especially as compared to foreign competitors, and could reduce demand. Global economic volatility has had a significant impact on the exchange markets, which heightened this risk, and we expect the higher level of volatility in foreign exchange markets will likely continue.
88

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all.
We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including supporting the development and introduction of new products, addressing new markets, engaging in strategic transactions and partnerships, improving or expanding our operating infrastructure or acquiring complementary businesses and technologies. Investments, partnerships and acquisitions involve risks and uncertainties which could adversely affect our operating and financial results. In December 2019, we issued and sold a total of $1,050 million in aggregate principal amount of our 0.50% Convertible Senior Notes due 2026 (the “2026 Notes”). In March 2022, we issued and sold a total of $861 million aggregate principal amount of our 0.50% Convertible Senior Notes due 2028 (the “2028 Notes”). In June 2023, we issued and sold a total of $603.7 million aggregate principal amount of our 1.50% Convertible Senior Notes due 2029 (“2029 Notes”). In September 2025, we issued and sold a total of $1,265.0 million aggregate principal amount of our 0.375% Convertible Senior Notes due 2032 (“2032 Notes”). In December 2025, we entered into a Credit Agreement providing for a senior secured revolving credit facility in an aggregate principal amount of $400.0 million, including a $23.0 million sublimit for the issuance of letters of credit. We may in the future engage in additional equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity, equity-linked or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing we may secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, uncertainty in the macroeconomic environment, increasing interest rates and other factors have resulted in volatility in the capital markets and less favorable financing terms. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be harmed.
If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business could be disrupted, which could harm our operating results.
We expect to appropriately scale our business, internal systems and organization, and to continue to improve our operational, financial and management controls, reporting systems and procedures. Growth in sales, combined with the challenges of managing geographically dispersed operations, can place a significant strain on our management systems and resources, and our anticipated growth in future operations could continue to place such a strain. The failure to effectively manage our growth could disrupt our business and harm our operating results, and even if we are able to upgrade our systems and expand our staff, any such expansion will likely be expensive and complex. Our ability to successfully offer our products and implement our business plan in evolving markets requires an effective planning and management process. In economic downturns, we must effectively manage our spending and operations to ensure our competitive position during the downturn, as well as our future opportunities when the economy improves, remains intact. The failure to effectively manage our spending and operations could disrupt our business and harm our operating results.
A widespread health crisis could adversely affect our business operations, financial performance, results of operations, financial position and the achievement of our strategic objectives.
The outbreak of a widespread health crisis, whether global in scope or localized in an area in which we, our customers or our suppliers do business, could have an adverse effect on our operations and the operations of our suppliers and customers. Potential impacts on our operations and financial performance include:
• significant reductions in demand for one or more of our products or a curtailment to one or more of our product lines caused by, among other things, any temporary inability of our customers to purchase and utilize our products due to shutdown orders or financial hardship;
• workforce constraints triggered by any applicable shutdown orders or stay-at-home policies;
• disruptions to our third-party contract manufacturing and raw materials supply arrangements caused by constraints over our suppliers’ workforce capacity, financial, or operational difficulties;
• disruption in our own ability to produce and ship products;
89

• heightened risk and uncertainty regarding the loss or disruption of essential third-party service providers, including transportation services, contract manufacturing, marketing, and distribution services;
• requirements to comply with governmental and regulatory responses such as quarantines, import/export restrictions, price controls, or other governmental or regulatory actions, including closures or other restrictions that limit or close our operating and manufacturing facilities, restrict our workforce’s ability to travel or perform necessary business functions, or otherwise impact our suppliers or customers, which could adversely impact our operating results;
• general economic uncertainty in key global markets and financial market volatility; and
• increased operating expenses and potentially reduced efficiency of operations.
The ultimate impact of any future widespread health crisis on our operations and financial performance depends on many factors that are not within our control, including, but not limited, to: governmental, business and individuals’ actions that may be taken in response to the crisis; the impact of the crisis and actions taken in response on global and regional economies, travel, and economic activity; general economic uncertainty in key global markets and financial market volatility, including increasing levels of inflation in the United States; and global economic conditions and levels of economic growth. In addition, the global economic volatility related to any health crisis may significantly impact the foreign exchange markets, and the currencies of various countries in which we operate and in which we have significant volume of local-currency denominated expenses creating significant volatility.
Any failure, disruption or security breach or incident of or impacting our information technology infrastructure or information management systems could have an adverse impact on our business and operations.
Our business depends significantly on effective and efficient information management systems, and the reliability and security of our information technology infrastructure are essential to the operation, health and expansion of our business. For example, the information gathered and processed by our information management systems assists us in managing our supply chain, financial reporting, monitoring customer accounts, and protecting our proprietary and confidential business information, plans, trade secrets, and intellectual property, among other things. In addition, these systems may contain personal data or other confidential or otherwise protected information about our employees, our customers’ employees, or other business partners. We must continue to expand and update this infrastructure in response to our changing requirements as well as evolving security standards and risks.
In some cases, we may rely on third-party providers of hosting, support and other services to meet our information technology requirements. Any failure to manage, expand and update our information technology infrastructure, including our ERP system and other applications, any failure in the extension implementation or operation of this infrastructure, or any failure by our hosting and support partners or other third-party service providers in the performance of their services could harm our business. In addition, we have partnered with third parties to support our information technology systems and to help design, build, test, implement and maintain our information management systems. Our merger, acquisition and divestiture activity may also require transitions to or from, and the integration of, various information management systems within our overall enterprise architecture, including our ERP system and other applications. Those systems that we acquire or that are used by acquired entities or businesses may also pose security risks of which we are unaware or unable to mitigate, particularly during the transition of these systems.
90

Like other companies, we are subject to ongoing attempts by malicious actors, including through hacking, malware, ransomware, denial-of-service attacks, social engineering, exploitation of internet-connected devices, and other attacks, to obtain unauthorized access to, or acquisition or other processing of confidential or other information or otherwise affect service reliability and threaten the confidentiality, integrity and availability of our systems and information stored or otherwise processed on our systems. Cyber threats have increased in recent years, in part due to increased remote work and frequent attacks, including in the form of phishing emails, malware attachments and malicious websites. Additionally, geopolitical tensions and conflicts, such as the Russia-Ukraine war and ongoing conflicts in the Middle East, including the recent escalation of the U.S-Iran war, may increase our risks of cyber-attacks. Further, as artificial intelligence (“AI”) capabilities improve and become increasingly commonplace, cyber-attacks leveraging AI technology are likely to pose increasing threats. These attacks could, for example, leverage AI to directly attack information systems with increased speed and/or efficiency compared to a human threat actor or to create more effective phishing emails. In addition, a vulnerability could be introduced from the result of us and our third-party service providers incorporating output of an AI tool, such as AI-generated source code, that includes a threat. While we work to safeguard our internal network systems and validate the security of our third-party service providers to mitigate these potential risks, including through information security policies and employee awareness and training, there is no assurance that such actions have been or will be sufficient to prevent cyber-attacks or security breaches or incidents. We have been in the past, and may be in the future, subject to social engineering attacks and other cyber-attacks, and these attacks may become more prevalent with substantial portion of our workforce being distributed geographically, particularly given the increased remote access to our networks and systems as a result. Further, our third-party service providers may have been and may be in the future subject to such attacks or otherwise may suffer security breaches or incidents. In addition, actions by our employees, service providers, partners, contractors, or others, whether malicious or in error, could affect the security of our systems and information. Further, a breach or compromise of our information technology infrastructure or that of our third-party service providers could result in the misappropriation of intellectual property, business plans, trade secrets or other information. Additionally, while our security systems are designed to maintain the physical security of our facilities and information systems, accidental or willful security breaches or incidents or other unauthorized access by third parties to our facilities or our information systems could lead to unauthorized access to, or misappropriation, disclosure, or other processing of proprietary, confidential and other information. Moreover, evolving laws and regulations, such as the European Union’s General Data Protection Regulation (“GDPR”), the California Consumer Privacy Act (“CCPA”), and China’s Personal Information Protection Law, add to the complexity of our compliance obligations and increases our compliance costs. Although we have established internal controls and procedures intended to comply with such laws and regulations, any actual or alleged failure to fully comply could result in significant penalties and other liabilities, harm to our reputation and market position, business and financial condition.
Despite our implementation of security measures, our systems and those of our third-party service providers are vulnerable to damage from these or other types of attacks, errors, acts or omissions. In addition, our systems may be impacted by natural disasters, terrorism or other similar disruptions. Any system failure, disruption, accident or security breach or incident affecting us or our third-party service providers could result in disruptions to our operations and loss or unavailability of, or unauthorized access or damage to, inappropriate access to, or use, disclosure or other processing of confidential information and other information maintained or otherwise processed by us on our behalf. Any actual or alleged disruption to, or security breach or incident affecting, our systems or those of our third-party partners could cause significant damage to our reputation, lead to theft or misappropriation of our intellectual property and trade secrets, result in claims, investigations, and other proceedings by or before regulators, and claims, demands and litigation, legal obligations or liability, affect our relationships with our customers, require us to bear significant remediation and other costs and ultimately harm our business, financial condition and operating results. In addition, we may be required to incur significant costs to protect against or mitigate damage caused by disruptions or security breaches or incidents. Our costs incurred in efforts to prevent, detect, alleviate or otherwise address cybersecurity or other security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant and such efforts may not be successful. All of these costs, expenses, liability and other matters may not be covered adequately by insurance and may result in an increase in our costs for insurance or insurance not being available to us on economically feasible terms, or at all. Insurers may also deny us coverage as to any future claim. Any of these results could harm our financial condition, business and reputation.
91

Our revenues, operating results, and cash flows may fluctuate from period to period due to a number of factors, which makes predicting financial results difficult.
Spending on optical communication and laser products is subject to cyclical and uneven fluctuations, which could cause our financial results to fluctuate unpredictably. It can be difficult to predict the degree to which end-customer demand and the seasonality and uneven sales patterns of our OEM partners or other customers will affect our business in the future, particularly as we or they release new or enhanced products. We are also subject to changes in buying patterns among our OEM partners and other customers, including unpredictable changes in their desired inventory levels. Further, if our revenue mix changes, it may also cause results to differ from historical seasonality. Accordingly, our quarterly and annual revenues, operating results, cash flows, and other financial and operating metrics have and may in the future vary significantly in the future. We attempt to identify changes in market conditions as soon as possible; however, the dynamics of the market in which we operate make prediction of and timely reaction to such events difficult. Due to these and other factors, the results of any prior periods should not be relied on as an indication of future performance. Quarterly fluctuations from the above factors may cause our revenue, operating results, and cash flows to underperform in relation to our guidance, long-term financial targets or the expectations of financial analysts or investors, which may cause volatility or decreases in our stock price.
If we have insufficient proprietary rights or if we fail to protect our rights, our business would be harmed.
We seek to protect our products and product roadmaps in part by developing and/or securing proprietary rights relating to those products, including patents, trade secrets, know-how and continuing technological innovation. Protecting against the unauthorized use of our products, technology and other proprietary rights is difficult, time-consuming and expensive; therefore, the steps we take to protect our intellectual property may not adequately prevent misappropriation or ensure that others will not develop competitive technologies or products. Other companies may be investigating or developing technologies that are similar to our own. Additionally, there may be existing patents that we are unaware of, which could be pertinent to our business. It is not possible for us to know whether there are patent applications pending that our products might infringe on since these applications are often not made publicly available until a patent is issued or published. It is possible that patents may not be issued from any of our pending applications or those we may file in the future and, if patents are issued, the claims allowed may not be sufficiently broad to deter or prohibit others from making, using or selling products that are similar to ours, or such patents could be invalidated or ruled unenforceable. We do not own patents in every country in which we sell or distribute our products, and thus others may be able to offer identical products in countries where we do not have intellectual property protections. In addition, the laws of some territories in which our products are or may be developed, manufactured or sold, including Europe, Asia-Pacific or Latin America, may not protect our products and intellectual property rights to the same extent as the laws of the United States. Any patents issued to us may be challenged, invalidated or circumvented. Additionally, we are currently a licensee for a number of third-party technologies including software and intellectual property rights from academic institutions, our competitors and others, and we are required to pay royalties to these licensors for the use thereof. In the future, if such licenses are unavailable or if we are unable to obtain such licenses on commercially reasonable terms, we may not be able to rely on such third-party technologies which could inhibit our development of new products, impede the sale of some of our current products, substantially increase the cost to provide these products to our customers, and could have a significant adverse impact on our operating results.
We also seek to protect our important trademarks by endeavoring to register them in certain countries. We have not registered our trademarks in every country in which we sell or distribute our products, and thus others may be able to use the same or confusingly similar marks in countries where we do not have trademark registrations. Trademarks associated with the Lumentum brand have been registered in the United States or other jurisdictions, however, the efforts we take to maintain registration and protect trademarks, including the Lumentum brand, may not be sufficient or effective. Although we have registered marks associated with the Lumentum brand, third parties may seek to oppose or otherwise challenge these registrations. There is the possibility that, despite efforts, the scope of the protection obtained for our trademarks, including the Lumentum brand, will be insufficient or that a registration may be deemed invalid or unenforceable in one or more jurisdictions throughout the world.
Further, a breach of our information technology infrastructure could result in the misappropriation of intellectual property, business plans or trade secrets. Any failure of our systems or those of our third-party service providers could result in unauthorized access or acquisition of such proprietary information, and any actual or perceived security breach could cause significant damage to our reputation and adversely impact our relationships with our customers.
92

Further, governments and courts are considering new issues in intellectual property law with respect to work created by AI technology, which could result in different intellectual property rights in development processes, procedures and technologies we create with AI technology, which could have an adverse effect on our business.
Our products may be subject to claims that they infringe the intellectual property rights of others, the resolution of which may be time-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.
Lawsuits and allegations of patent infringement and violation of other intellectual property rights occur regularly in our industry. We have in the past received, and anticipate that we will receive in the future, notices from third parties claiming that our products infringe on their proprietary rights, with two distinct sources of such claims becoming increasingly prevalent. First, large technology companies, including some of our customers and competitors, are seeking to monetize their patent portfolios and have developed large internal organizations that may approach us with demands to enter into license agreements. Second, patent-holding companies that do not make or sell products (often referred to as “patent trolls”) may claim that our products infringe on their proprietary rights. We respond to these claims in the course of our business operations. The litigation or settlement of these matters, regardless of the merit of the claims, could result in significant expense and divert the efforts of our technical and management personnel, regardless of whether or not we are successful. If we are unsuccessful, we could be required to expend significant resources to develop non-infringing technology or to obtain licenses to the technology that is the subject of the litigation. We may not be successful in such development, or such licenses may not be available on commercially reasonable terms, or at all. Without such a license, or if we are the subject of an exclusionary order, our ability to make our products could be limited and we could be enjoined from future sales of the infringing product or products, which could adversely affect our revenues and operating results. Additionally, we often indemnify our customers against claims of infringement related to our products and may incur significant expenses to defend against such claims. If we are unsuccessful defending against such claims, we may be required to indemnify our customers against any damages awarded.
We also face risks that third parties may assert trademark infringement claims against us in one or more jurisdictions throughout the world related to our brands and/or other trademarks and our exposure to these risks may increase as a result of acquisitions. The litigation or settlement of these matters, regardless of the merit of the claims, could result in significant expense and divert the efforts of our technical and management personnel, regardless of whether or not we are successful. If we are unsuccessful, trademark infringement claims against us could result in significant monetary liability or prevent us from selling some or all of our products or services under the challenged trademark. In addition, resolution of claims may require us to alter our products, labels or packaging, license rights from third parties, or cease using the challenged trademark altogether, which could adversely affect our revenues and operating results.
We face certain litigation risks that could harm our business.
We are now, and in the future, may become subject to various legal proceedings and claims that arise in or outside the ordinary course of business. The results of legal proceedings are difficult to predict. Moreover, many of the complaints filed against us may not specify the amount of damages that plaintiffs seek, and we therefore may be unable to estimate the possible range of damages that might be incurred should these lawsuits be resolved against us. While we may be unable to estimate the potential damages arising from such lawsuits, certain of them assert types of claims that, if resolved against us, could give rise to substantial damages or restrictions on or changes to our business. Thus, an unfavorable outcome or settlement of one or more of these lawsuits could have an adverse effect on our financial condition, liquidity and results of operations. Even if these lawsuits are not resolved against us, the uncertainty and expense associated with unresolved lawsuits could seriously harm our business, financial condition and reputation. Litigation is generally costly, time-consuming and disruptive to normal business operations. The costs of defending these lawsuits have been significant in the past, will continue to be costly and may not be covered by our insurance policies. The defense of these lawsuits could also result in continued diversion of our management’s time and attention away from business operations, which could harm our business.

Our products incorporate and rely on licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.
We integrate licensed third-party technology into certain of our products. From time-to-time, we may be required to license additional technology from third parties to develop new products or product enhancements. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open-source software, may result in our inability to continue to use such license. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could potentially require us to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.
If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.
As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, and the Nasdaq Global Select Market (“Nasdaq”) listing requirements. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, and to integrate our acquisitions into our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant time and operational resources, including accounting-related costs and significant management oversight.
Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could cause us to delay reporting of our financial results, be subject to one or more investigations or enforcement actions by state or federal regulatory agencies, stockholder lawsuits or other adverse actions requiring us to incur defense costs, pay fines, settlements or judgments. Any such failures could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock and customer perception of our business may suffer. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on Nasdaq.
Risks Related to Our Indebtedness
Servicing our existing and future indebtedness, including the 2026 Notes, 2028 Notes, 2029 Notes and 2032 Notes (collectively referred to as the “convertible notes”) and any revolving loans under our Credit Agreement (as defined in the next risk factor below), may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under the convertible notes and our Credit Agreement, and our current and future indebtedness may limit our operating flexibility or otherwise affect our business.
Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness under the convertible notes, or to make cash payments in connection with any conversion of the convertible notes or upon any fundamental change if holders of the applicable series of the convertible notes require us to repurchase their convertible notes for cash, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our indebtedness and make necessary capital expenditures. In addition, during the three months ended March 28, 2026, the last reported sale price of the Company’s common stock was at least 130% of the applicable conversion price of each of the respective convertible notes in effect for at least 20 trading days during the last 30 trading days in the three months ended March 28, 2026; therefore, the convertible notes are convertible at the option of the holders with the principal balance to be settled in cash. To the extent all convertible note holders elect to convert all or a significant portion of the convertible notes within a short period of time, our liquidity would be adversely impacted, and could adversely impact our ability to continue as a going concern. If we are unable to generate sufficient cash flow to meet our obligations, we may be required to adopt one or more alternatives, such as selling assets, restructuring indebtedness or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, our existing and future indebtedness could have important consequences to our stockholders and significant effects on our business. For example, it could:
94

• make it more difficult for us to satisfy our debt obligations under the convertible notes or our Credit Agreement;
• increase our vulnerability to general adverse economic and industry conditions;
• require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital and other general corporate purposes;
• limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;
• restrict us from exploiting business opportunities;
• place us at a competitive disadvantage compared to our competitors that have less indebtedness; and
• limit our availability to borrow additional funds for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other general purposes.
Any of these factors could harm our business, results of operations, and financial condition. In addition, we and our subsidiaries may be able to incur significant additional indebtedness in the future. If we incur additional indebtedness, the risks related to our business and our ability to service or repay our indebtedness would increase.
Our revolving credit facility contains financial covenants and other covenants that may restrict our actions, and failure to comply with these covenants could have a material adverse effect on our financial condition.
On December 19, 2025, we entered into a credit agreement (the “Credit Agreement”) with the lenders party thereto and Wells Fargo Bank, National Association, as administrative and collateral agent. The Credit Agreement provides for a senior secured revolving credit facility in an aggregate principal amount of $400.0 million, including a $23.0 million sublimit for the issuance of letters of credit. As of March 28, 2026, there were no borrowings outstanding under the revolving credit facility.
Our Credit Agreement contains covenants that limit our ability and the ability of certain of our subsidiaries to, among other things, incur liens, make investments, incur indebtedness, merge or consolidate with other companies, sell substantially all of our assets, make restricted payments, enter into certain transactions with affiliates and make certain prepayments of subordinated debt, in each case subject to certain exceptions. In addition, the Credit Agreement contains financial covenants that require compliance with a maximum secured net leverage ratio and minimum interest coverage ratio, in each case tested at the end of each fiscal quarter. These covenants may adversely affect our ability to finance our operations, meet or otherwise address our capital needs, pursue business opportunities or react to market conditions, or otherwise restrict our activities or business plans. In addition, our obligations to repay principal and interest on our indebtedness could make us vulnerable to economic or market downturns. Our ability to comply with these covenants depends on many factors, some of which are beyond our control.
The Credit Agreement contains various events of default that include, among others, non-payment of principal, interest or fees, inaccuracy of representations and warranties, breach of covenants, cross default to certain other indebtedness, bankruptcy and insolvency events, material judgments and events constituting a change of control, subject to thresholds and cure periods as set forth in the Credit Agreement. Upon the occurrence and during the continuance of an event of default, the Lenders may terminate their commitments and accelerate the Company’s obligations under the Credit Agreement and may exercise certain other rights and remedies provided for under the Credit Agreement, the other loan documents and applicable law. If outstanding borrowings under the Credit Agreement were accelerated, we may not have sufficient cash on hand or be able to borrow sufficient funds to refinance the debt or sell sufficient assets to repay the debt, which could immediately adversely affect our business, cash flows, results of operations, and financial condition.

Risks Related to Human Capital
Our ability to develop, market and sell products could be harmed if we are unable to retain or hire key personnel.
Our future success depends on our ability to recruit and retain the services of executive, engineering, manufacturing, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or salespeople specializing in the service provider, enterprise and commercial laser markets, is limited and competition for such individuals is intense. Competition is particularly intense in certain jurisdictions where we have research and development centers, including Silicon Valley, and for engineering talent generally. Competition is also intense and turnover is high in certain jurisdictions where we or our suppliers have manufacturing facilities. Also, the increase of remote work among employees in our industries has increased employee mobility and turnover, making it difficult for us to retain or hire employees. Further, to attract and retain top talent, we have offered, and we believe we will need to continue to offer, competitive compensation and benefits packages. Job candidates and existing employees often consider the value of the equity awards they receive in connection with their employment. If the perceived value of our equity awards declines, it may adversely affect our ability to attract and retain highly qualified employees. There can be no assurance that the programs, initiatives, rewards and recognition that are part of our people strategy will be successful in attracting and retaining the talent necessary to execute on our business plans. In addition, as a result of our past and any future acquisitions and related integration activities, our current and prospective employees may experience uncertainty about their futures that may impair our ability to retain, recruit, or motivate key management, engineering, technical and other personnel. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future, particularly during the integration of acquisitions, or delays in hiring required personnel and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products. Similarly, the failure to properly manage the necessary knowledge transfer required for employee transitions could impact our ability to meet customers’ needs, to work effectively with customers, suppliers or other third parties, or to maintain industry and innovation leadership. The loss of members of our management team or other key personnel could be disruptive to our business and, were it necessary, it could be difficult to replace such individuals. If we are unable to attract and retain qualified personnel, we may be unable to manage our business effectively, and our business, financial condition and results of operations may be harmed.
Our ability to hire and retain employees may be negatively impacted by changes in immigration laws, regulations and procedures.
Foreign nationals who are not U.S. citizens or permanent residents constitute an important part of our U.S. workforce, particularly in the areas of engineering and product development. Our ability to hire and retain these workers and their ability to remain and work in the United States are impacted by laws and regulations, as well as by procedures and enforcement practices of various government agencies and global events that may interfere with our ability to hire or retain workers who require visas or entry permits. For example, if the U.S. implements travel restrictions or changes visa requirements, our ability to hire and retain employees could be impacted. Additional changes in immigration laws, regulations or procedures in jurisdictions in which we hire workers may adversely affect our ability to hire or retain such workers, increase our operating expenses and negatively impact our ability to deliver our products and services.
96

Risks Related to Legal, Regulatory and Compliance
Our sales may decline if we are unable to obtain government authorization to export certain of our products, and we may be subject to legal and regulatory consequences if we do not comply with applicable export control laws and regulations.
Exports of certain of our products are subject to export controls imposed by the U.S. government and administered by the U.S. Departments of State and Commerce. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to the EAR administered by the BIS, the requirement for a license is dependent on the type and end use of the product, the final destination, the identity of the end user and whether a license exception might apply. Virtually all exports of products subject to the International Traffic in Arms Regulations (“ITAR”) administered by the Department of State’s Directorate of Defense Trade Controls, require a license. Certain of our fiber optics products are subject to EAR and ITAR. Products and the associated technical data developed and manufactured in our foreign locations are subject to export controls of the applicable foreign nation. There is no assurance that we will be issued these licenses or be granted exceptions, and failure to obtain such licenses or exceptions could limit our ability to sell our products into certain countries and negatively impact our business, financial condition and/or operating results.
The requirement to obtain a license could put us at a competitive disadvantage by restricting our ability to sell products to customers in certain countries or by giving rise to delays or expenses related to obtaining a license. Given the current global political climate, obtaining export licenses can be difficult and time-consuming. Failure to obtain export licenses for these shipments could significantly reduce our revenue and adversely affect our business, financial condition, relationships with our customers and results of operations. Compliance with U.S. government regulations also subjects us to additional fees and costs. The absence of comparable restrictions on competitors in other countries may adversely affect our competitive position.
Further, there is increased attention from the government and the media regarding potential threats to U.S. national security and foreign policy relating to certain foreign entities, particularly Chinese entities, and the imposition of enhanced restrictions or sanctions regarding the export of our products or on specific foreign entities that would restrict their ability to do business with U.S. companies may adversely affect our business. For example, on May 16, 2019, Huawei was added to the Entity List, additional regulatory restrictions were imposed in May and August 2020 and in October 2022 to the Foreign-Produced Direct Product Rule, which impose limitations on the supply of certain U.S. items and product support to Huawei, and FiberHome Technologies was added to the Entity List on May 22, 2020. These actions have resulted in escalating tensions between the U.S. and China and create the possibility that the Chinese government may take additional steps to retaliate against U.S. companies or industries. We currently do not supply any products to Huawei, and we cannot predict whether we will again be able to sell to Huawei. Further, we cannot predict what additional actions the U.S. government may take with respect to Huawei beyond what is described above or to other of our customers, including modifications to or interpretations of Entity List restrictions, export restrictions, tariffs, or other trade limitations or barriers.
Our association with customers that are or become subject to U.S. regulatory scrutiny or export restrictions could negatively impact our business. Governmental actions such as these could subject us to actual or perceived reputational harm among current or prospective investors, suppliers or customers, customers of our customers, other parties doing business with us, or the general public. Any such reputational harm could result in the loss of investors, suppliers or customers, which could harm our business, financial condition, operating results or prospects. Our failure or perceived failure to comply with any of the foregoing legal and regulatory requirements, or other actual or asserted obligations relating to export controls has in the past and could in the future result in increased costs for our products, damage to our reputation, government inquiries, subpoenas, investigations. If we fail to comply with any of these export regulations, we could be subject to civil, criminal, monetary and non-monetary penalties and costly consent decrees, which would lead to disruptions to our business, restrictions on our ability to export products and technology, and adversely affect our business and results of operation.
In addition, certain of our significant customers and suppliers have products that are subject to U.S. export controls, and therefore these customers and suppliers may also be subject to legal and regulatory consequences if they do not comply with applicable export control laws and regulations. Such regulatory consequences could disrupt our ability to obtain components from our suppliers, or to sell our products to major customers, which could significantly increase our costs, reduce our revenue and adversely affect our business, financial condition and results of operations.
97

Social and environmental responsibility regulations, policies and provisions, as well as customer and investor demands, may make our supply chain more complex and may adversely affect our relationships with customers and investors.
There is an increasing focus on environmental, social, and governance (“ESG”) matters both in the United States and globally. A number of our customers have adopted, or may adopt, procurement policies that include social and environmental responsibility provisions or requirements that their suppliers should comply with, or they may seek to include such provisions or requirements in their procurement terms and conditions. These legal and regulatory requirements, as well as investor expectations, on corporate environmental and social responsibility practices and disclosure, are subject to change, can be unpredictable, and may be difficult and expensive for us to comply with, given the complexity of our supply chain. If we are unable to comply with, or are unable to cause our suppliers or contract manufacturers to comply with such policies or provisions, or if we are unable to meet the requirements of our customers and investors, a customer may stop purchasing products from us or an investor may sell their shares, and may take legal action against us, which could harm our reputation, revenue and results of operations. We expect to face increasing worldwide regulatory activity relating to climate change in the future. Future compliance with these laws and regulations, as well as meeting related customer and investor expectations, may adversely affect our business and results of operations.
Our reputation and/or business could be negatively impacted by ESG matters and/or our reporting of such matters.
We have in the past and may in the future communicate certain ESG-related initiatives regarding sustainability matters, fair labor practices, responsible sourcing, and other matters in a Corporate Social Responsibility Report, on our website, in certain filings with the SEC, and elsewhere. These initiatives could be difficult to achieve and costly to implement. In addition, we could be criticized for the timing, scope or nature of these initiatives, or for our disclosures related to such matters, or for our policies and practices related to these matters. Opinions, perspectives, and expectations on sustainability and governance matters may differ amongst our stakeholders and may evolve over time. We have been and may continue to be subject to conflicting expectations and views on various matters, and legal requirements and interpretations may change. Our actual or perceived failure to meet evolving stakeholder expectations, or achieve any required ESG-related initiatives, could negatively impact our reputation or otherwise harm our business.
We may be adversely affected by climate change regulations.
In many of the jurisdictions in which we operate, government bodies are increasingly enacting legislation and regulations in response to potential impacts of climate change. These laws and regulations are mandatory in some cases, and have the potential to impact our operations directly or indirectly as a result of required compliance by our customers or supply chain. Inconsistency of regulations may also 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.
We may incur increased capital expenditures resulting from required compliance with revised or new legislation or regulations, added costs to purchase raw materials, lower profits from sales of our products, increased insurance premiums and deductibles, changes in competitive position relative to industry peers, changes to profit or loss arising from increased or decreased demand for goods produced by us, or changes in costs of goods sold, which would have an adverse effect on our business, financial condition and results of operations.
We are subject to laws and regulations worldwide including with respect to environmental matters, securities laws, privacy and data protection, compliance with which could increase our expenses and harm our operating results.
Our operations and our products are subject to various federal, state and foreign laws and regulations, including those governing pollution and protection of human health and the environment in the jurisdictions in which we operate or sell our products. These laws and regulations govern, among other things, wastewater discharges and the handling and disposal of hazardous materials in our products. Our failure to comply with current and future environmental or health or safety requirements could cause us to incur substantial costs, including significant capital expenditures, to comply with such environmental laws and regulations and to clean up contaminated properties that we own or operate. Such clean-up or compliance obligations could result in disruptions to our operations. Additionally, if we are found to be in violation of these laws, we could be subject to governmental fines or civil liability for damages resulting from such violations. These costs could have an adverse impact on our financial condition or operating results.
98

From time-to-time new regulations are enacted, and it is difficult to anticipate how such regulations will be implemented and enforced. We continue to evaluate the necessary steps for compliance with regulations as they are enacted. These regulations include, for example, the Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”), the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive (“RoHS”) and the Waste Electrical and Electronic Equipment Directive (“WEEE”) enacted in the European Union which regulate the use of certain hazardous substances in, and require the collection, reuse and recycling of waste from, certain products we manufacture. These regulations and similar legislation may require us to re-design our products to ensure compliance with the applicable standards, for example by requiring the use of different types of materials, which could have an adverse impact on the performance of our products, add greater testing lead-times for product introductions or other similar effects. We believe we comply with all such legislation where our products are sold, and we continuously monitor these laws and the regulations being adopted under them to determine our responsibilities.
In addition, pursuant to Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC has promulgated rules requiring disclosure regarding the use of certain “conflict minerals” that are mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer’s efforts to prevent the sourcing of such minerals. We may face challenges with government regulators and our customers and suppliers if we are unable to sufficiently make any required determination that the metals used in our products are conflict free. Complying with these disclosure requirements involves substantial diligence efforts to determine the source of any conflict minerals used in our products and may require third-party auditing of our diligence process. These efforts may demand internal resources that would otherwise be directed towards operations activities.
Since our supply chain is complex, we may face reputational challenges if we are unable to sufficiently verify the origins of all minerals used in our products. Additionally, if we are unable to satisfy those customers who require that all of the components of our products are determined to be conflict free, they may choose a competitor’s products which could materially impact our financial condition and operating results.
We are also subject to laws and regulations relating to our collection, use, protection and other processing of personal data of our employees, customers and others. These laws and regulations are subject to frequent modifications and updates and require ongoing supervision. For example, the European Union adopted the GDPR, which became effective in May 2018, establishing stringent requirements for data protection in Europe and providing for substantial penalties for noncompliance. Additionally, California has the CCPA, which went into effect on January 1, 2020, and which was amended and supplemented by California Privacy Rights Act (“CPRA”), which went into effect on January 1, 2023. Other legislation relating to privacy, data protection and cybersecurity has been proposed or adopted in several other states, including the enactment of legislation similar to the CCPA and CPRA enacted in numerous states. Aspects of the CCPA, CPRA and these other laws and regulations, as well as their enforcement, remain unclear. The U.S. federal government also is contemplating federal privacy legislation, and the U.S. Department of Justice has issued regulations restricting certain bulk transfers of sensitive personal data. The effects and impact of these or other laws and regulations relating to privacy, data protection and cybersecurity are potentially significant and may require us to modify practices and policies and to incur substantial costs and expenses in efforts to comply. Laws and regulations relating to privacy, data protection and cybersecurity continue to evolve in various jurisdictions, with existing laws and regulations subject to new and differing interpretations and new laws and regulations being proposed and adopted. It is possible that our practices may be deemed not to comply with those legal requirements relating to privacy, data protection and cybersecurity that apply to us now or in the future.
Further, the United Kingdom has implemented legislation similar to the GDPR, including the UK Data Protection Act and legislation referred to as the UK GDPR, which provides for substantial penalties, similar to the GDPR. The United Kingdom made targeted amendments to this legislation in 2025. Aspects of United Kingdom data protection law remains unclear following the United Kingdom’s exit from the European Union, including with respect to data transfers between the United Kingdom and other jurisdictions. The European Commission has adopted an adequacy determination regarding the United Kingdom data protection regime that generally has permitted personal data to be transferred between the European Economic Area (“EEA”) and the United Kingdom, which it renewed in 2025 to extend through December 2031. The European Commission’s adequacy decision is, however, subject to potential revocation or modification. We cannot fully predict how the Data Protection Act, the UK GDPR, and other United Kingdom data protection laws or regulations may develop in the medium to longer term nor the effects of divergent laws and guidance regarding data transfers. We may find it necessary to make further changes to our handling of personal data of residents of the EEA, Switzerland and the United Kingdom, each of which may require us to incur significant costs and expenses.
99

New technology trends, such as AI, require us to keep pace with evolving regulations and industry standards. In the United States, the European Union, and China there are various current and proposed regulatory frameworks relating to the development and use of AI in products and services. We expect that the legal and regulatory environment relating to emerging technologies such as AI will continue to develop and could increase the cost of doing business, and create compliance risks and potential liability, all which may have an adverse effect on our financial condition and results of operations.
Our failure or perceived failure to comply with any of the foregoing legal and regulatory requirements, or other actual or asserted obligations relating to privacy, data protection or cybersecurity could result in increased costs for our products, monetary penalties, damage to our reputation, government inquiries, subpoenas, investigations and other legal proceedings, legal claims, demands and litigation and other obligations and liabilities. Furthermore, the legal and regulatory requirements that are applicable to our business are subject to change from time-to-time, which increases our monitoring and compliance costs and the risk that we may fall out of compliance or for this to be alleged to have occurred. Additionally, we may be required to ensure that our suppliers comply with applicable laws and regulations. If we or our suppliers fail or are perceived to fail to comply with such laws or regulations, we could face sanctions for such noncompliance, and our customers may refuse to purchase our products, which would have an adverse effect on our business, financial condition and results of operations.
Risks Related to Our Common Stock
Our stock price may be volatile and may decline regardless of our operating performance.
Our common stock is listed on the Nasdaq Global Select Market under the symbol “LITE.” The market price of our common stock has fluctuated in the past and may fluctuate significantly due to a number of factors, some of which may be beyond our control and may often be unrelated or disproportionate to our operating performance. These include:
• general economic and market conditions and other external factors;
• changes in global economic conditions, including those resulting from trade tensions, rising inflation, and fluctuations in foreign currency exchange and interest rates;
• speculation in the press or investment community about our strategic position;
• actual or anticipated fluctuations in our quarterly or annual operating results;
• changes in earnings estimates by securities analysts or our ability to meet those estimates;
• the operating and stock price performance of other comparable companies;
• a shift in our investor base;
• the financial performance of other companies in our industry, and of our customers;
• general market, economic and political conditions, including market conditions in the semiconductor industry;
• pandemics and similar major health concerns;
• success or failure of our business strategy;
• credit market fluctuations which could negatively impact our ability to obtain financing as needed;
• changes in governmental regulation including taxation and tariff policies;
• changes in global political tensions that may affect business with our customers, such as trade wars caused by or resulting in the imposition of heightened or scheduled proposed tariffs or the possibility of future tariffs;
• announcements by us, competitors, customers, or our contract manufacturers of significant acquisitions or dispositions, strategic alliances or overall movement toward industry consolidations among our customers and competitors;
• investor perception of us and our industry;
100

• changes in recommendations by securities analysts;
• changes in accounting standards, policies, guidance, interpretations or principles;
• differences, whether actual or perceived, between our corporate social responsibility and ESG practices and disclosure and government or customer, business partner, investor or other stakeholder expectations;
• litigation or disputes in which we may become involved;
• overall market fluctuations;
• issuances of our shares upon conversion of some or all of the convertible notes; and
• sales of our shares by our officers, directors, or significant stockholders.
In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business, results of operations, financial condition and cash flows.
Transactions relating to our convertible notes may dilute the ownership interest of existing stockholders, or may otherwise depress the price of our common stock.
Following our entry into the First Supplemental Indenture, dated as of September 25, 2024, to the 2026 Indenture and our irrevocable settlement method elections made on September 25, 2024 with respect to the 2028 Notes and 2029 Notes, and pursuant to the terms of our 2032 Notes, if the convertible notes are converted by holders, we are required to satisfy our conversion obligation with respect to the convertible notes by delivering cash equal to the principal amount of such converted convertible notes and cash, shares of common stock, or a combination of cash and shares of common stock, at our election, with respect to any conversion value in excess thereof. If we elect to deliver common stock upon conversion of the convertible notes, it would dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, certain holders of the convertible notes may engage in short selling to hedge their position in the convertible notes. Anticipated future conversions of the convertible notes into shares of our common stock could depress the price of our common stock.
We do not expect to pay dividends on our common stock.
We do not currently expect to pay dividends on our common stock. The payment of any dividends to our stockholders in the future, and the timing and amount thereof, if any, is within the discretion of our board of directors. Our board of directors’ decisions regarding the payment of dividends will depend on many factors, such as our financial condition, earnings, capital requirements, potential debt service obligations or restrictive covenants, industry practice, legal requirements, regulatory constraints and other factors that our board of directors deems relevant. As a result, the success of an investment in our common stock will depend on future appreciation in its value. There is no guarantee that our common stock will maintain its value or appreciate in value.
In addition, because we are a holding company with no material direct operations, we are dependent on loans, dividends and other payments from our operating subsidiaries to generate the funds necessary to pay dividends on our common stock. However, our operating subsidiaries’ ability to make such distributions will be subject to their operating results, cash requirements and financial condition and the applicable provisions of Delaware law that may limit the amount of funds available for distribution. Our ability to pay cash dividends may also be subject to covenants and financial ratios related to existing or future indebtedness, and other agreements with third parties.
101

Certain provisions in our charter and Delaware corporate law could hinder a takeover attempt.
We are subject to the provisions of Section 203 of the Delaware General Corporate Law which prohibits us, under some circumstances, from engaging in business combinations with some stockholders for a specified period of time without the approval of the holders of substantially all of our outstanding voting stock. Such provisions could delay or impede the removal of incumbent directors and could make more difficult a merger, tender offer or proxy contest involving us, even if such events could be beneficial, in the short-term, to the interests of our stockholders. In addition, such provisions could limit the price that some investors might be willing to pay in the future for shares of our common stock. Our certificate of incorporation and bylaws contain provisions providing for the limitations of liability and indemnification of our directors and officers, allowing vacancies on our board of directors to be filled by the vote of a majority of the remaining directors, granting our board of directors the authority to establish additional series of preferred stock and to designate the rights, preferences and privileges of such shares (commonly known as “blank check preferred”) and providing that our stockholders can take action only at a duly called annual or special meeting of stockholders, which may only be called by the chairman of the board of directors, the chief executive officer or the board of directors. These provisions may also have the effect of deterring hostile takeovers or delaying changes in control or changes in our management.
Our bylaws designate Delaware courts as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could discourage lawsuits against us or our directors and officers.
Our bylaws provide that, unless we consent in writing to an alternative forum, the state or federal courts of Delaware are the sole and exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting breach of fiduciary duty, or other wrongdoing, by our directors, officers or other employees to us or our stockholders; any action asserting a claim against Lumentum pursuant to the Delaware General Corporation Law or our certificate of incorporation or bylaws; any action asserting a claim against Lumentum governed by the internal affairs doctrine; or any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or bylaws. This exclusive forum provision may limit the ability of our stockholders to bring a claim in a different judicial forum that such stockholders find favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us or our directors and officers.
Alternatively, if a court outside of Delaware were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.
The 2032 Capped Call Options may affect the value of our common stock.
In connection with the issuance of the 2032 Notes, we entered into the 2032 Capped Call Options with the 2032 Capped Call Counterparties. We have been advised that the 2032 Capped Call Counterparties may modify the hedge positions they established when they entered into the 2032 Capped Call Options by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the 2032 Notes (and are likely to do so in connection with any conversion, repurchase or redemption of the 2032 Notes or if we unwind all or a portion of the 2032 Capped Call Options). This activity could cause or prevent an increase or a decrease in the market price of our common stock.
102

We are subject to counterparty risk with respect to the 2032 Capped Call Options.
The 2032 Capped Call Counterparties are financial institutions, and we will be subject to the risk that one or more of the 2032 Capped Call Counterparties may default under the 2032 Capped Call Options. Our exposure to the credit risk of the 2032 Capped Call Counterparties will not be secured by any collateral.
Global economic conditions have in the past resulted in the actual or perceived failure and/or financial difficulties of many financial institutions. If a 2032 Capped Call Counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under the 2032 Capped Call Option with such 2032 Capped Call Counterparty. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our common stock increases. In addition, upon a default by a 2032 Capped Call Counterparty, we may suffer adverse tax consequences and experience more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the 2032 Capped Call Counterparties.
