 Manufacturing
 As of June 28, 2025, we have significant manufacturing facilities for our NSE and OSP segments located in China, France, Germany, the United Kingdom and the United States. Our most significant contract manufacturing partners are located in China and Thailand.
 Sources and Availability of Raw Materials
 We use various suppliers and contract manufacturers to supply parts and components for the manufacture and support of multiple product lines. Although we intend to establish at least two sources of supply for materials whenever possible, for certain components we have sole or limited source supply arrangements.
 Patents and Proprietary Rights
 Intellectual property rights apply to our various products include patents, trade secrets and trademarks. We do not intend to broadly license our intellectual property rights unless we can obtain adequate consideration or enter into acceptable intellectual property cross-licensing agreements. As of June 28, 2025, we own approximately 1,085 U.S. patents and 2,075 foreign patents and have 1,164 patent applications pending throughout the world. The average age of the patents we hold is 9.0 years, which is younger than the midpoint of the average 20-year life of a patent.
 Backlog
 Due to possible changes in product delivery schedules and cancellation of product orders, and because our sales often reflect orders shipped in the same quarter in which they are received, our backlog at any particular date is not necessarily indicative of actual revenue or the level of orders for any succeeding period.
 Seasonality
 Our business is seasonal, as is typical for our competitors and many large companies. For our NSE segment, revenue is typically higher in the second and fourth fiscal quarters, all else being equal. There is typically a modest end of calendar year customer spending budget that benefits our second fiscal quarter. Telecom and cable spending budgets are typically set at the start of a new calendar year, thus with all else being equal, our third fiscal quarter is NSE's weakest revenue quarter with spending release benefiting our fourth fiscal quarter.
 For our OSP business, given our exposure to the consumer market, namely our 3D sensing products into the smartphone market, OSP revenue is expected to be seasonally higher in the first and second fiscal quarters followed by seasonal demand declines in the third and fourth fiscal quarters.

 ITEM 1A. RISK FACTORS
 Global Risks
 Geopolitical conditions, including political turmoil and volatility, regional conflicts, terrorism and war could result in market instability, which could negatively impact our business results.
 We operate globally and sell our products in countries throughout the world. Recent escalation in regional conflicts, including the Russian invasion of Ukraine, resulting in ongoing and expanding economic sanctions, conflict in the Middle East, and the risk of increased tensions between the U.S. and China, could curtail or prohibit our ability to transfer certain technologies, to sell our products and solutions, or to continue to operate in certain locations. Foreign companies with a presence in China are facing increasing operational challenges and enhanced scrutiny from governmental entities in the region. Further, it is possible that the U.S.-Chinese geopolitical tensions could result in government measures that could adversely impact our business. In September 2023, a bill was introduced by the House Financial Services Committee that would authorize sanctions on certain Chinese entities in China's defense and surveillance technology sectors. This could have an adverse impact on our revenues in this region. Further, the U.S. administration has implemented and could implement further broad-based global tariffs that could adversely impact trade relations and result in higher costs. The final timing and amount of tariff rates continues to evolve and therefore the impact, including those of any potential retaliatory tariffs, is difficult to forecast. International conflict has contributed to (i) increased pressure on the supply chain and could further result in increased energy costs, which could increase the cost of manufacturing, selling and delivering products and solutions (ii) inflation, which could result in increases in the cost of manufacturing products, reduced customer purchasing power, increased price pressure, and reduced or cancelled orders (iii) increased risk of cybersecurity attacks and (iv) general market instability, all of which could adversely impact our financial results.
 Risks Related to Our Business Strategy and Industry
 Our future profitability is not assured.
 Our profitability in a particular period will be impacted by revenue, product mix and operational costs that vary significantly across our product portfolio and business segments.
 Specific factors that may undermine our profit and financial objectives include, among others:
 • Uncertainty around the timing of our customers procurement decisions on infrastructure maintenance and upgrades;
 • Uncertain future telecom carrier and cable operator capital and R&D spending levels, which particularly affects our NSE segment;
 • Adverse changes to our product mix, both fundamentally (resulting from new product transitions, the declining profitability of certain legacy products and the termination of certain products with declining margins, among other things) and due to quarterly demand fluctuations;
 • Pricing pressure across our NSE product lines due to competitive forces, particularly from Asia-based competitors, advanced chip component shortages, and a highly concentrated customer base for many of our product lines, which may offset some of the cost improvements;
 • Strategic execution challenges arising from competition with larger and more well-resourced competitors;
 • Our OSP segment operating margin may experience some downward pressure as a result of a higher mix of 3D sensing products and increased operating expenses;
 • Limited availability of components and resources for our products which leads to higher component prices;
 • Resource rationing, including rationing of utilities like electricity by governments and/or service providers;
 • Budgetary constraints that impact or slow customer inventory consumption;
 • Increasing commoditization of previously differentiated products, and the attendant negative effect on average selling prices and profit margins;
 • Execution challenges, which limit revenue opportunities and harm profitability, market opportunities and customer relations;
 • Decreased revenue associated with terminated or divested product lines;
 • Redundant costs related to periodic transitioning of manufacturing and other functions to lower-cost locations;

 • Ongoing costs associated with organizational transitions, consolidations and restructurings, which are expected to continue in the nearer term;
 • Cyclical demand for our currency products;
 • Changing market and economic conditions, including impacts due to tariffs, economic sanctions and export restrictions, the ongoing conflict between Russia and Ukraine, conflict in the Middle East, tensions and trade sanctions between the U.S. and China, supply chain constraints, pricing and inflationary pressures;
 • Ability of our customers, partners, manufacturers and suppliers to purchase, market, sell, manufacture and/or supply our products and services, including as a result of disruptions arising from supply chain constraints;
 • Financial stability of our customers, including the solvency of private sector customers and statutory authority for government customers to purchase goods and services; and
 • Factors beyond our control resulting from pandemics and similar outbreaks, manufacturing restrictions, travel restrictions and shelter-in-place orders to control the spread of a disease regionally and globally, and limitations on the ability of our employees and our suppliers' and customers' employees to work and travel.
 Taken together, these factors limit our ability to predict future profitability levels and to achieve our long-term profitability objectives. If we fail to achieve profitability expectations, the price of our debt and equity securities, as well as our business and financial condition, may be materially adversely impacted.
 Rapid technological change in our industry presents us with significant risks and challenges, and if we are unable to keep up with the rapid changes, our customers may purchase less of our products.
 Our success depends upon our ability to deliver both our current product offerings and new products and technologies on time and at an acceptable cost to our customers. The markets for our products are characterized by rapid technological change, frequent new product introductions, substantial capital investment, changes in customer requirements and a constantly evolving industry. Our future performance will depend on the successful development, introduction and market acceptance of new and enhanced products that address these issues and provide solutions that meet our customers' current and future needs. As a technology company, we also constantly encounter quality, volume and cost concerns such as:
 • Our continuing cost reduction programs, which include site and organization consolidations, asset divestitures, outsourcing the manufacture of certain products to contract manufacturers, other outsourcing initiatives and reductions in employee headcount, requirements related to re-establishment and re-qualification by our customers of complex manufacturing lines, and modifications to systems, planning and operational infrastructure. During this process, we have experienced, and may continue to experience, additional costs, delays in re-establishing volume production levels, planning difficulties, inventory issues, factory absorption concerns and systems integration problems.
 • Variability of manufacturing yields caused by difficulties in the manufacturing process, the effects from a shift in product mix, changes in product specifications and the introduction of new product lines. These difficulties can reduce yields or disrupt production and thereby increase our manufacturing costs and adversely affect our margin.
 • Potentially significant costs to correct defective products (despite rigorous testing for quality both by our customers and by us), which could include lost future sales of the affected product and other products, and potentially severe customer relations problems, litigation and damage to our reputation.
 • Our dependence on a limited number of vendors, who are often small and specialized, for raw materials, packages and standard components. We also rely on contract manufacturers around the world to manufacture certain products. Our business could continue to be adversely affected by this dependency. Specific concerns we periodically encounter with our suppliers include stoppages or delays of supply, insufficient vendor resources to supply our requirements, substitution of more expensive or less reliable parts, receipt of defective parts or contaminated materials, increases in the price of supplies and an inability to obtain reduced pricing from our suppliers in response to competitive pressures. Additionally, the ability of our contract manufacturers to fulfill their obligations may be affected by economic, political or other forces that are beyond our control. Any such failure could have a material impact on our ability to meet customers' expectations and may materially impact our operating results.

 • New product programs and introductions, which involve changing product specifications and customer requirements, unanticipated engineering complexities, difficulties in reallocating resources and overcoming resource limitations and increased complexity, exposing us to yield and product risk internally and with our suppliers.
 These factors could cause strain on our execution capabilities and customer relations. We expect the impact of these issues will become more pronounced as we continue to introduce new product offerings and when overall demand increases. We have seen and could continue to see periodic difficulty responding to customer delivery expectations for some of our products, and yield and quality problems, particularly with some of our new products and higher volume products which could require additional funds and other resources to respond to these execution challenges. From time to time, we have had to divert resources from new product R&D and other functions to assist with resolving these matters. If we do not improve our performance in these areas, our operating results may be harmed, the commercial viability of new products may be challenged, and our customers may choose to reduce or terminate their purchases of our products and purchase additional products from our competitors.
 Unfavorable, uncertain or unexpected conditions in the transition to new technologies may cause our growth forecasts to be inaccurate and/or cause fluctuations in our financial results.
 Growth forecasts are subject to significant uncertainty and are based on assumptions and estimates which may not prove to be accurate. Our estimates of the market opportunities related to network infrastructure, 3D sensing and other developing technologies, including AI, are subject to significant uncertainty and are based on assumptions and estimates, including our internal analysis, industry experience and third-party data. Accordingly, these markets may not develop in the manner or in the time periods we anticipate, and our estimated market opportunities may prove to be materially inaccurate.
 If domestic and global economic conditions worsen, including as a result of pricing and inflationary pressures, overall spending on infrastructure, 3D sensing and other developing technologies may be reduced, which would adversely impact demand for our products in these markets. In addition, unfavorable developments with evolving laws and regulations worldwide related to such technologies may limit or slow the rate of global adoption, impede our strategy, and negatively impact our long-term expectations in these markets.
 Our growth and ability to serve a significant portion of these markets are subject to many factors including our success in implementing our business strategy as well as market adoption and expansion of network infrastructure, 3D sensing and other applications for consumer electronics. We may not be able to serve a significant portion of these markets and our growth forecasts should not be taken as indicative of our future growth. Even if the markets and rates of adoption develop in the manner or in the time periods we anticipate, if we do not have timely, competitively priced, market-accepted products available to meet our customers' planned roll-out of infrastructure platforms and systems, 3D sensing products and other technologies, we may miss a significant opportunity and our business, financial condition, results of operations and cash flows could be materially and adversely affected.
 We may experience increased pressure on our pricing and contract terms due to our reliance on a limited number of customers for a significant portion of our sales.
 We believe that we will continue to rely upon a limited number of customers for a significant portion of our revenues for the foreseeable future. Any failure by us to continue capturing a significant share of key customer sales could materially harm our business. Dependence on a limited number of customers exposes us to the risk that order reductions from any one customer can have a material adverse effect on periodic revenue. Due to the current trend of communication industry consolidation, we may have increased dependence on fewer customers who may be able to exert increased pressure on our prices and other contract terms. Customer consolidation activity and periodic manufacturing and inventory initiatives could also create the potential for disruptions in demand for our products as a consequence of such customers streamlining, reducing or delaying purchasing decisions.
 We have a strategic alliance with SICPA to market and sell our OVP and OVMP product lines for banknote anti-counterfeiting applications worldwide. A material reduction in sales, or loss of the relationship with SICPA, may harm our business and operating results as we may be unable to find a substitute marketing and sales partner or develop these capabilities ourselves in a timely manner.

 Movement towards virtualized networks and software solutions may result in lower demand for our hardware products and increased competition.
 The market for our NSE segment is increasingly looking towards virtualized networks and software solutions. This trend may result in lower demand for our legacy hardware products. Additionally, barriers to entry are generally lower for software solutions, which may lead to increased competition for our products, solutions and services.
 We face a number of risks related to our strategic transactions.
 Our strategy continues to include periodic acquisitions and divestitures of businesses and technologies. Strategic transactions of this nature involve numerous risks, including the following:
 • Competition for suitable acquisition targets;
 • Inability to consummate deals on favorable or acceptable terms, or due to failure to obtain stockholder, government, regulatory or other necessary approvals or satisfy other closing conditions;
 • Diversion of management's attention from normal daily operations of the business;
 • Potential difficulties in completing projects associated with in-process R
 • Difficulties in entering markets in which we have no or limited prior experience and where competitors have stronger market positions;
 • Difficulties in obtaining or providing sufficient transition services and accurately projecting the time and cost associated with providing these services;
 • Inability of an acquisition to further our business strategy as expected or overpay for, or otherwise not realize the expected return on our investments;
 • Expected earn-outs may not be achieved in the time frame or at the level expected or at all;
 • Lack of ability to recognize or capitalize on expected growth, synergies or cost savings;
 • Insufficient net revenue to offset increased expenses associated with acquisitions;
 • Potential loss of key employees of the acquired companies;
 • Difficulty in forecasting revenues and margins;
 • Adverse public health developments, epidemic disease or pandemics in the countries in which we operate or our customers are located, including regional quarantines restricting the movement of people or goods, reductions in labor supply or staffing, the closure of facilities to protect employees, including those of our customers, disruptions to global supply chains and both our and our suppliers' ability to deliver materials and products on a timely or cost-effective basis, shipment, acceptance or verification delays, the resulting overall significant volatility and disruption of financial markets, and economic instability affecting customer spending patterns; and
 • Inadequate internal control procedures and disclosure controls to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or poor integration of a target company's or business's procedures and controls.
 Acquisitions may also cause us to:
 • Issue common stock that would dilute our current stockholders' percentage ownership and may decrease earnings per share;
 • Assume liabilities, some of which may be unknown at the time of the acquisitions;
 • Record goodwill and non-amortizable intangible assets that will be subject to impairment testing and potential periodic impairment charges;
 • Incur additional debt to finance such acquisitions;
 • Incur amortization expenses related to certain intangible assets; and/or
 • Acquire, assume, or become subject to litigation related to the acquired businesses or assets.

 VIAVI is subject to risks associated with its recent and proposed acquisitions, including completion of proposed acquisitions in the anticipated timeframes or at all, and any failure to realize anticipated benefits of such acquisitions.
 In January 2025, VIAVI completed the acquisition of Inertial Labs, Inc. (the Inertial Labs Acquisition). VIAVI also previously announced its proposed acquisition of Spirent Communications plc's (Spirent) high-speed ethernet and network security business lines from Keysight Technologies, Inc., (the Proposed Acquisition), which is currently estimated to close by the end of September 2025, subject to customary closing conditions. VIAVI is subject to risks and uncertainties associated with the Proposed Acquisition, including the risk that a condition to closing may not be satisfied or waived, the possibility of failure to obtain any outstanding necessary regulatory approvals, which may be outside the control of VIAVI or Keysight Technologies, Inc., or the possibility that the Proposed Acquisition does not close in the anticipated timeframe or at all.
 VIAVI may not be able to realize the anticipated benefits of the Inertial Labs Acquisition or the Proposed Acquisition, including synergies, value creation or other benefits of such acquisitions, fully or at all, or on the timeline VIAVI expects. At times, the resources of VIAVI and the acquired businesses or the attention of certain members of their management may be focused on completion and integration of the acquisition and diverted from day-to-day business operations, which may disrupt ongoing business. In addition, the process of integrating the acquired businesses may have an adverse impact on the Company, including from risks related to significant transaction and integration costs, unknown liabilities, employee turnover, divergence of management attention, litigation and/or regulatory actions related to the acquisition or if the acquired business does not perform as expected, which may cause an adverse financial impact on the Company.
 We may not generate positive returns on our research and development strategy.
 Developing our products is expensive, and the investment in product development may involve a long payback cycle. We expect to continue to invest heavily in R&D in order to expand the capabilities of 3D sensing and smart phone sensors, handheld spectrometer solution and portable test instruments, introduce new products and features and build upon our technology. We expect that our results of operations may be impacted by the timing and size of these investments. In addition, these investments may take several years to generate positive returns, if ever.
 Operational Risks
 Our restructuring activities could adversely affect our business and results of operations.
 We have from time-to-time engaged in restructuring activities to realign our cost base with current and anticipated future market conditions, including the restructuring programs initiated during fiscal 2023 and fiscal 2024. Significant risks associated with these types of actions that may impair our ability to achieve the anticipated cost reductions or disrupt our business include delays in the implementation of anticipated workforce reductions in highly regulated locations outside of the U.S. and the failure to meet operational targets due to the loss of key employees. In addition, our ability to achieve the anticipated cost savings and other benefits from these actions within the expected timeframe is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we experience delays, or if other unforeseen events occur, our business and results of operations could be adversely affected.

 Management transitions and talent retention create uncertainties that could harm our business.
 Management changes could adversely impact our results of operations and our customer relationships and may make recruiting for future management positions more difficult. Our executives and other key personnel are generally at-will employees, we generally do not have employment or non-compete agreements with our other employees, and we cannot assure you that we will be able to retain them. We have in the past experienced, and could continue to experience changes in our leadership team. Competition for people with the specific technical and other skills we require is significant. We could be impacted by new restrictions imposed by the U.S. government on, or curtailing of H1-B and other work visas and permits. We and our impacted and prospective employees may face greater evidentiary burden to prove eligibility for immigration benefits. Further, employees in certain categories may not be able to renew work authorizations or benefit from automatic extensions of work permits. We may face difficulties in attracting, retaining and motivating employees. If we are unable to attract and retain qualified executives and employees, or to successfully integrate any newly hired personnel within our organization, we may be unable to achieve our operating objectives, which could negatively impact our financial performance and results of operations.
 We face risks related to our international operations and revenue.
 Our customers are located throughout the world. In addition, we have significant operations outside North America, including product development, manufacturing, sales and customer support operations.
 Our international presence exposes us to certain risks, including the following:
 • Fluctuations in exchange rates between the U.S. dollar and among the currencies of the countries in which we do business may adversely affect our operating results by negatively impacting our revenues or increasing our expenses;
 • Our ability to comply with the laws and regulations of the countries in which we do business, including, among others, customs, import/export, product compliance, economic sanctions, anti-bribery, anti-competition, climate/sustainability regulations, and tax and data privacy laws, which may be subject to sudden and unexpected changes;
 • Difficulties in establishing and enforcing our intellectual property rights;
 • Tariffs and other trade restrictions;
 • Political, legal and economic instability in foreign markets, particularly in those markets in which we maintain manufacturing and product development facilities;
 • Strained or worsening relations between the U.S., Russia and China and related impacts on other countries;
 • Difficulties in staffing and management;
 • Language and cultural barriers;
 • Seasonal reductions in business activities in the countries where our international customers are located;
 • Integration of foreign operations;
 • Longer payment cycles;
 • Difficulties in management of foreign distributors; and
 • Potential adverse tax consequences.
 Global and regional health pandemics have affected and may in the future affect the manufacturing and shipment of goods globally. Any delay in production or delivery of our products due to an extended closure of our suppliers' plants could adversely impact our business, along with delays in shipment of our products as well as increased logistics costs.
 We expect that net revenue from customers outside North America will continue to account for a significant portion of our total net revenue. Lower sales levels that typically occur during the summer months in Europe and some other overseas markets may materially and adversely affect our business. In addition, the revenues we derive from many of our customers depend on international sales and further expose us to the risks associated with such international sales.

 Information Security, Technology and Intellectual Property Risks
 Our business and operations could be adversely impacted in the event of a failure of information technology infrastructure.
 We rely upon the capacity, reliability and security of our information technology infrastructure and our ability to expand and continually update this infrastructure in response to our changing needs. In some cases, we rely upon third-party hosting and support services to meet these needs. We and our third-party providers have experienced increasingly sophisticated cybersecurity attacks, which can take the form of phishing emails, malware, malicious websites, ransomware, exploitation of application vulnerabilities, and nation-state attacks. These kinds of attacks or threats of attacks can lead to increased operational impairment; intellectual property theft; fraud; extortion; harm to employees or customers; violation of privacy or security laws and other litigation and legal risks; and reputational risks. The growing and evolving cyber-risk environment means that individuals, companies, and organizations of all sizes, including ourselves, our customers, suppliers and our hosting and support partners, are increasingly vulnerable to attacks and disruptions on their networks and systems by a wide range of actors on an ongoing and regular basis. We also design and manage IT systems and products that contain IT systems for various customers, and generally face the same threats for these systems as for our own internal systems.
 Our network security controls are comprised of administrative, physical and technical controls, which include, but are not limited to, the implementation of firewalls, anti-virus protection, patches, log monitors, routine backups, off-site storage, network audits and other routine updates and modifications. We also routinely monitor and develop our internal information technology systems to address risks to our information systems. However, there can be no assurance that the controls we implement and internal information technology systems we develop will be adequate and successful. Our systems are regularly targeted by bad actors and, in some cases, have been affected by computer viruses, natural disasters, unauthorized access and other similar disruptions and attacks that continue to emerge and evolve. Any system failure, accident or security breach could result in disruptions to our business processes, network degradation, and system downtime, along with the potential that a third-party will gain unauthorized access to, or acquire intellectual property, proprietary business information, and data related to our employees, customers, suppliers, and business partners, including personal data. While we maintain system data and security logs, our logging also may not be sufficient to fully investigate a security incident. To the extent that any disruption, degradation, downtime or other security event results in a loss or damage to our data or systems, or in inappropriate disclosure of confidential or personal information, it could adversely impact us and our clients, potentially resulting in, among other things, financial losses, loss of customers or business, our inability to transact business on behalf of our clients, adverse impact on our brand and reputation, violations of applicable privacy and other laws, regulatory fines, penalties, litigation, reimbursement or other compensation costs, and/or additional compliance costs. We may also incur additional costs related to cybersecurity risk management and remediation. We or our service providers, if applicable, may suffer losses relating to cyber-attacks or other information security breaches in the future and any insurance coverage may not be adequate to cover all the costs resulting from such events. Our efforts to reduce the risk of such attacks or to detect attacks that occur may not be successful.
 If we have insufficient proprietary rights or if we fail to protect those we have, our business would be materially harmed.
 We seek to protect our products and our 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. The steps taken by us to protect our intellectual property may not adequately prevent misappropriation or ensure that others will not develop competitive technologies or products and the costs associated with protecting our intellectual property may outweigh the benefits. Other companies may be investigating or developing other technologies that are similar to our own. 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. 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 protection. 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 U.S.

 Any patents issued to us may be challenged, invalidated or circumvented. Additionally, we are currently a licensee in all of our operating segments for a number of third-party technologies, software and intellectual property rights from academic institutions, our competitors and others, and are required to pay royalties to these licensors for the use thereof. Unless we are able to obtain such licenses on commercially reasonable terms, patents or other intellectual property held by others 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. In the past, licenses generally have been available to us where third-party technology was necessary or useful for the development or production of our products. However, in the future licenses to third-party technology may not be available on commercially reasonable terms, if at all.
 Our products may be subject to claims that they infringe the intellectual property rights of others.
 Lawsuits and allegations of patent infringement and violation of other intellectual property rights occur in our industry on a regular basis. We have received in the past, and anticipate that we will receive in the future, notices from third parties claiming that our products infringe their proprietary rights. Over the past several years there has been a marked increase in the number and potential severity of third-party patent infringement claims, primarily from two distinct sources. 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 have approached us with demands to enter into license agreements. Second, patent-holding companies, entities that do not make or sell products (often referred to as "patent trolls"), have claimed that our products infringe upon their proprietary rights. We will continue to respond to these claims in the course of our business operations. In the past, the resolution of these disputes has not had a material adverse impact on our business or financial condition; however, this may not be the case in the future. Further, the litigation or settlement of these matters, regardless of the merit of the claims, could result in significant expense to us and divert the efforts of our technical and management personnel, 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 terms acceptable to us, if at all. Without such a license, we could be enjoined from future sales of the infringing product or products, which could adversely affect our revenues and operating results.
 The use of open-source software and generative artificial intelligence may expose us to risks and harm our intellectual property position.
 Certain of the software and/or firmware that we use and distribute (as well as that of our suppliers, manufacturers and customers) may be, derived from, or contain, "open-source" software, which is software that is generally made available to the public by its authors and/or other third parties, as well as generative artificial intelligence (GenAI) technology (discussed further below). Such open-source software is often made available under licenses which impose obligations in the event the software or derivative works thereof are distributed or re-distributed. These obligations may require us to make source code for the derivative works available to the public, and/or license such derivative works under a particular type of license, rather than the forms of license customarily used to protect our own software products. In the event that a court rules that these licenses are unenforceable, or in the event the copyright holder of any open-source software were to successfully establish in court that we had not complied with the terms of a license for a particular work, we could be required to release the source code of that work to the public and/or stop distribution of that work. Additionally, open-source licenses are subject to occasional revision. In the event future iterations of open-source software are made available under a revised license, such license revisions may adversely affect our ability to use such future iterations.
 Similarly, GenAI technology has proliferated including as a feature in existing commercially available products, some of which we use. GenAI is a type of machine-learning model capable of generating various types of content, including data, text and images. Use of GenAI tools could expose us to data and network security risks. These risks include the exposure of our intellectual property, confidential and proprietary information (including customer information) to unknown recipients; the introduction of malware into our network; and the creation of content subject to copyright, trademark, or other intellectual property protection of an unknown third party.

 Legal, Regulatory and Compliance Risks
 Certain of our products are subject to governmental and industry regulations, certifications and approvals.
 The commercialization of certain of the products we design, manufacture and distribute may be more costly due to required government approval and industry acceptance processes. For example, in our OSP segment, development of applications for our anti-counterfeiting and special effects pigments may require significant testing that could delay our sales. In addition, durability testing by the automobile industry of our special effects pigments used with automotive paints can take up to three years. If we change a product for any reason, including technological changes or changes in the manufacturing process, prior approvals or certifications may be invalid and we may need to go through the approval process again. If we are unable to obtain these or other government or industry certifications in a timely manner, or at all, our operating results could be adversely affected.
 We receive formal and informal government inquiries or audits related to our products, practices or services from time to time.
 We receive formal and informal inquiries from, or become subject to, investigations by various government authorities regarding our business and compliance with federal, state and local laws, regulations, or standards. Any determination or allegation that our operations, products, activities, or the activities of our employees, contractors or agents, are not in compliance with existing laws, regulations or standards, could adversely affect our business. Even if such inquiries or investigations do not result in the imposition of fines, interruptions to our business, loss of suppliers or other third-party relationships, terminations of necessary licenses and permits, the existence of those inquiries or investigations alone could create negative publicity that could cause business or reputational harm.
 U.S. government trade actions and restrictions could have an adverse impact on our business, financial position, and results of operation.
 The U.S. and China have been engaged in protracted negotiations over the Chinese government's acts, policies, and practices related to technology transfer, intellectual property, and innovation.
 Huawei Technologies Co. Ltd. and a score of non-U.S. affiliates (collectively, Huawei) are on the Entity List of the Bureau of Industry and Security of the U.S. Department of Commerce (BIS), which imposes limitations on the supply of certain U.S. items and product support to Huawei. BIS issued final rules that further restrict access by Huawei to items produced domestically and abroad from U.S. technology and software. Certain products of VIAVI are subject to the restrictions; however, the ongoing impact is not expected to be material to our overall operations.
 Moreover, the additional tariffs announced by the U.S. administration in 2025, or other trade actions that may be implemented, may increase the cost of certain materials and/or products, thereby adversely affecting our profitability. These actions could require us to pass these costs to our customers, which could decrease demand for our products, and could adversely impact our business.
 Furthermore, the geopolitical and economic uncertainty and/or instability that may result from changes in the relationship among the United States, Taiwan and China, may, directly or indirectly, materially harm our business, financial condition and results of operations. For example, certain of our suppliers are dependent on products sourced from Taiwan, which are prevalent in certain global markets, most specifically semiconductor manufacturing. Hence, greater restrictions and/or disruptions of our suppliers' ability to operate facilities and/or do business in these jurisdictions may increase the cost of certain materials and/or limit the supply of products and may result in deterioration of our profit margins, a potential need to increase our pricing and, in so doing, may decrease demand for our products and thereby adversely impact our revenue or profitability.
 Due to the ongoing conflict between Russia and Ukraine, the U.S., European Union (E.U.), and United Kingdom (U.K.) have broadened restrictions on supply to Russia, thereby blocking shipments of technology, telecommunications and consumer electronics products to Russia. We suspended transactions in the region effective February 2022 which negatively impacted our business in the region. The ongoing situation in Ukraine as well as the potential for additional trade actions or retaliatory cyber-attacks aimed at infrastructure or supply chains, could have an impact on our future operations and financial results.

 Failure to maintain satisfactory compliance with certain privacy and data protections laws and regulations may harm our business.
 Complex local, state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy laws and regulations are quickly evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. In addition, our legal and regulatory obligations in jurisdictions outside of the U.S. are subject to unexpected changes, including the potential for regulatory or other governmental entities to enact new or additional laws or regulations, to issue rulings that invalidate prior laws or regulations, or to increase penalties significantly. Complying with these laws and regulations can be costly and can impede the development and offering of new products and services. For example, the E.U. General Data Protection Regulation (GDPR), imposes stringent data protection requirements and provides for significant penalties for noncompliance. Additionally the California Consumer Privacy Act (CCPA) requires, among other things, covered companies to provide disclosures to California consumers, and allow such consumers new abilities to opt-out of certain sales of personal data. The CCPA also provides for civil penalties for violations, as well as a private right of action for data breaches that may increase data breach litigation. In recent years, many other states have enacted privacy laws that have gone or will go into effect and which impose additional data protection obligations on covered businesses, including consumer rights, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. The new and proposed privacy laws may result in further uncertainty and would require us to incur additional expenditures to comply. These regulations and legislative developments have potentially far-reaching consequences and may require us to modify our data management practices and incur substantial compliance expense.
 Our failure to comply with applicable laws and regulations or other obligations to which we may be subject relating to personal data, or to protect personal data from unauthorized access, use, or other processing, could result in enforcement actions and regulatory investigations against us, claims for damages by customers and other affected individuals, fines, damage to our reputation, and loss of goodwill, any of which could have a material adverse effect on our operations, financial performance, and business.
 Responsible Business Risks
 We may be subject to environmental liabilities.
 We are subject to various federal, state and foreign laws and regulations, including those governing pollution, protection of human health, the environment and recently, those restricting the presence of certain substances in electronic products as well as holding producers of those products financially responsible for the collection, treatment, recycling and disposal of certain products. Such laws and regulations, passed in several jurisdictions in which we operate, are often complex and are subject to frequent changes. We will need to ensure that we comply with such laws and regulations as they are enacted, as well as all other environmental laws and regulations. As appropriate or required, our component suppliers must also comply with such laws and regulations. If we fail to comply with such laws, we could face sanctions for such noncompliance, and our customers may refuse to purchase our products, which would have a materially adverse effect on our business, financial condition and results of operations.
 With respect to compliance with environmental laws and regulations in general, we have incurred, and in the future could incur, substantial costs for the cleanup of contaminated properties, either those we own or operate or to which we have sent wastes in the past, or to comply with such environmental laws and regulations. Additionally, we could be subject to disruptions to our operations and logistics as a result of such clean-up or compliance obligations. If we were found to be in violation of these laws, we could be subject to governmental fines and liability for damages resulting from such violations. If we have to make significant capital expenditures to comply with environmental laws, or if we are subject to significant expenditures in connection with a violation of these laws, our financial condition or operating results could be materially adversely impacted.

 Our business is subject to evolving regulations and expectations with respect to sustainability matters that could expose us to numerous risks.
 Regulators, customers, investors, employees and other stakeholders continue to focus on sustainability-related matters and related disclosures. These developments have resulted in, and are likely to continue to result in, increased general and administrative expenses and increased management time and attention spent complying with or meeting sustainability-related requirements and expectations. For example, developing and acting on sustainability-related initiatives and collecting, measuring and reporting sustainability-related information and metrics can be costly, difficult and time consuming and is subject to evolving reporting standards, including reporting requirements in California and other jurisdictions, such as the European Union which we may be subject to. We may also communicate certain initiatives and goals regarding sustainability-related matters in our public disclosures. These sustainability-related initiatives and goals could be difficult and expensive to implement, the technologies needed to implement them may not be cost effective and may not advance at a sufficient pace, and we could be criticized for the accuracy, adequacy or completeness of the disclosure. Further, statements about our sustainability-related initiatives and goals, and progress against those goals, may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. In addition, we could be criticized for the scope or nature of such initiatives or goals, or for any revisions to these goals. If our sustainability-related data, processes and reporting are incomplete or inaccurate, or if we fail to achieve progress with respect to our sustainability-related goals on a timely basis, or at all, our reputation, business, financial performance and growth could be adversely affected.
 We may be subject to risks related to climate change, natural disasters and catastrophic events.
 We operate in geographic regions which face a number of climate and environmental challenges. Our corporate headquarters is located in Chandler, Arizona, a desert climate, subject to extreme heat and drought. The geographic location of our Northern California offices and production facilities subject them to drought, earthquake and wildfire risks. It is impossible to predict the timing, magnitude or location of such natural disasters or their impacts on the local economy and on our operations. If a major earthquake, wildfire or other natural disaster were to damage or destroy our facilities or manufacturing equipment, we may experience potential impacts ranging from production and shipping delays to lost profits and revenues. In the past, we temporarily closed our Santa Rosa, California facility due to wildfires in the region and the facility's close proximity to the wildfire evacuation zone which resulted in production stoppage. The location of our production facility could subject us to production delays and/or equipment and property damage. Moreover, the public electric utility in our Northern California region, has previously implemented and may continue to implement widespread blackouts during the peak wildfire season to avoid and contain wildfires sparked during strong wind events by downed power lines or equipment failure. Ongoing blackouts, particularly if prolonged or frequent, could impact our operations going forward. Additionally, the occurrence of adverse public health developments, epidemic disease or pandemics may adversely affect our business, operations, financial condition, and results of operations. The extent to which global pandemics impact our business going forward will depend on factors such as the duration and scope of the pandemic; governmental, business, and individuals' actions in response to the pandemic; and the impact on economic activity, including the possibility of recession or financial market instability. Measures to contain a global pandemic may intensify other risks described in these Risk Factors.

 Risks Related to our Liquidity and Indebtedness
 Any deterioration or disruption of the capital and credit markets may adversely affect our access to sources of funding.
 Global economic conditions have caused and may cause volatility and disruptions in the capital and credit markets. When the capital or credit markets deteriorate or are disrupted, our ability to incur additional indebtedness to fund a portion of our working capital needs and other general corporate purposes, or to refinance maturing obligations as they become due, may be constrained. In the event that we were to seek to access the capital markets or other sources of financing, there can be no assurance that we will be able to obtain financing on acceptable terms or within an acceptable time, if at all. We may seek to access the capital or credit markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. For example, in December 2021, we entered into a $300 million asset-based secured credit facility (Senior Secured Asset-Based Revolving Credit Facility), maturing in December 2026, which has certain limitations based on our borrowing base capacity. The Company is currently considering reducing the commitment under the Senior Secured Asset-Based Revolving Credit Facility to $200 million to be in line with borrowing base capacity and extend the maturity. Our access to the financial markets and the pricing and terms we receive in the financial markets could be adversely impacted by various factors, including changes in financial markets and interest rates. In addition, if we do access the capital or credit markets, agreements governing any borrowing arrangement could contain covenants restricting our operations.
 Our term notes increased our overall leverage and our convertible notes could dilute our existing stockholders and lower our reported earnings per share.
 The issuance of our 1.625% Senior Convertible Notes due 2026 and our 3.75% Senior Notes due 2029 (together the "Notes") substantially increased our principal payment obligations. The degree to which we are leveraged could materially and adversely affect our ability to successfully obtain financing for working capital, acquisitions or other purposes and could make us more vulnerable to industry downturns and competitive pressures. In addition, the holders of the 2026 Notes are entitled to convert the Notes into shares of our common stock or a combination of cash and shares of common stock under certain circumstances which would dilute our existing stockholders and lower our reported per share earnings.
 Our ability to make payments on our indebtedness when due, to make payments upon conversion with respect to our convertible senior notes or to refinance our indebtedness as we may need or desire, depends on our future performance and our ability to generate cash flow from operations, which is subject to economic, financial, competitive and other factors beyond our control. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, refinancing or obtaining additional equity capital on terms that may be onerous or highly dilutive. We may not be able to engage in these activities on desirable terms or at all, which may result in a default on our existing or future indebtedness and harm our financial condition and operating results.
 Our outstanding indebtedness may limit our operational and financial flexibility.
 Our level of indebtedness could have important consequences, including:
 • Impairing our ability to obtain additional financing for working capital, capital expenditures, acquisitions or general corporate purposes;
 • Requiring us to dedicate a substantial portion of our operating cash flow to paying principal and interest on our indebtedness, thereby reducing the funds available for operations;
 • Limiting our ability to grow and make capital expenditures due to the financial covenants contained in our debt arrangements;
 • Impairing our ability to adjust rapidly to changing market conditions, invest in new or developing technologies, or take advantage of significant business opportunities that may arise;
 • Making us more vulnerable if a general economic downturn occurs or if our business experiences difficulties; and

 • Resulting in an event of default if we fail to satisfy our obligations under the Notes or our other debt or fail to comply with the financial and other restrictive covenants contained in the indentures governing the Notes, or any other debt instruments, which event of default could result in all of our debt becoming immediately due and payable and could permit certain of our lenders to foreclose on our assets securing such debt.
 We may not generate sufficient cash flow to meet our debt service and working capital requirements, which may expose us to the risk of default under our debt obligations.
 We will need to implement our business strategy successfully on a timely basis to meet our debt service and working capital needs. We may not successfully implement our business strategy, and even if we do, we may not realize the anticipated results of our strategy and generate sufficient operating cash flow to meet our debt service obligations and working capital needs. In addition, our ability to make scheduled payments on our indebtedness, including the Notes, is affected by general and regional economic, financial, competitive, business and other factors beyond our control. For example, we generate cash in a number of jurisdictions globally, including China, in which there can be challenges to repatriate those funds which can impact our overall liquidity.
 In the event our cash flow is inadequate to meet our debt service and working capital requirements, we may be required, to the extent permitted under the indentures covering the Notes and any other debt agreements, to seek additional financing in the debt or equity markets, refinance or restructure all or a portion of our indebtedness, sell selected assets or reduce or delay planned capital or operating expenditures. Any insufficient cash flow may make it more difficult for us to obtain financing on terms that are acceptable to us, or at all.
 Despite our current level of indebtedness, we and our subsidiaries may still be able to incur substantially more debt.
 We and our subsidiaries may be able to incur significant additional indebtedness in the future. The indentures that govern the Notes and the agreement that governs our secured credit facility contain restrictions on the incurrence of additional indebtedness, which are subject to a number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these restrictions could be substantial. These restrictions also will not prevent us from incurring obligations that do not constitute indebtedness under the agreements governing our existing debt. For example, in March 2025, we obtained commitments for a $425 million 7-year term loan facility the proceeds of which would be available, subject to customary conditions, in connection with our pending acquisition of Spirent's high-speed ethernet and network security business from Keysight Technologies, Inc. We subsequently marketed and upsized to a $600 million 7-year term loan facility and successfully allocated the loan to prospective lenders at an initial interest rate of SOFR+2.50% and an original issue price of 99.75%. The incremental $175 million is intended for general corporate purposes. The term loan funding, as upsized, remains subject to customary closing conditions and the satisfaction or waiver of all closing conditions to the pending acquisition.
 The terms of the indentures that govern the Notes and the agreement that governs our secured credit facility restrict our current and future operations.
 The indentures governing the Notes and the agreement governing the secured credit facility contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our ability to:
 • Incur or guarantee additional indebtedness;
 • Incur or suffer to exist liens securing indebtedness;
 • Make investments;
 • Consolidate, merge or transfer all or substantially all of our assets;
 • Sell assets;
 • Pay dividends or other distributions on, redeem or repurchase capital stock;
 • Enter into transactions with affiliates;
 • Amend, modify, prepay or redeem subordinated indebtedness;
 • Enter into certain restrictive agreements;
 • Engage in a new line of business;
 • Amend certain material agreements, including material leases and debt agreements; and

 • Enter into sale leaseback transactions.
 Tax Risks
 Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to certain limitations and/or changes in regulations.
 Changes in U.S. federal income or other tax laws or the interpretation of tax laws may impact our tax liabilities. Utilization of our net operating losses (NOLs) and tax credit carryforwards may be subject to a substantial annual limitation if the ownership change limitations under Sections 382 and 383 of the Internal Revenue Code and similar state provisions are triggered by changes in the ownership of our capital stock. In general, an ownership change occurs if there is a cumulative change in our ownership by "5-percent shareholders" that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. Accordingly, purchases of our capital stock by others could limit our ability to utilize our NOLs and tax credit carryforwards in the future.
 Furthermore, we may not be able to generate sufficient taxable income to utilize our NOLs and tax credit carryforwards before they expire. Due to uncertainty regarding the timing and extent of our future profitability, we continue to record a valuation allowance to offset our U.S. and certain of our foreign deferred tax assets because of uncertainty related to our ability to utilize our NOLs and tax credit carryforwards before they expire.
 If any of these events occur, we may not derive some or all of the expected benefits from our NOLs and tax credit carryforwards.
 Changes in tax legislation or policies could materially impact our financial position and results of operations.
 VIAVI operates in many jurisdictions around the world. Global tax policy is in a heightened state of evolution, with particular attention to Base Erosion and Profit Shifting (BEPS), transfer pricing, and general corporate tax reform. Any substantial changes in domestic or international corporate tax policies, regulations, or guidance may materially adversely affect our business, the amount of taxes we are required to pay, and our financial condition and results of operations generally. Enforcement activities or legislative initiatives may also have similar effects.
 The Organization for Economic Co-operation and Development (OECD) issued the BEPS Pillar Two Model Rules, which establish a minimum global effective tax rate of 15% on the profits of large multinational companies. Although the United States has not adopted these rules, many countries in which we operate have either implemented or are expected to implement the OECD Pillar Two framework. These developments may increase our tax burden, reduce net income, and impact cash flow.
 The Pillar Two rules generally became effective starting with VIAVI's fiscal 2025. We consider these laws when recording our income tax provision under ASC 740.
 In June 2025, the United States and the G7 countries announced an agreement in principle to modify the Pillar Two rules. Under this agreement, the foreign and domestic profits of U.S.-parented groups would be excluded from Pillar Two's undertaxed profit rule and income inclusion rule. In exchange, the U.S. withdrew the Section 899 tax provision from the One Big Beautiful Bill Act (OBBBA), which had imposed a retaliatory tax on individuals and entities from countries that implement certain "unfair foreign taxes" against U.S. companies or citizens. The G7-US agreement has not yet been enacted into law, and we continue to evaluate our Pillar Two position based on legislation currently in force. We will monitor tax developments for any future implications with respect to our tax burden, net income, and cash flow.

 General Risks
 Certain provisions in our charter and under Delaware laws could hinder a takeover attempt.
 We are subject to the provisions of Section 203 of the Delaware General Corporation Law prohibiting, under some circumstances, publicly-held Delaware corporations 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. Our certificate of incorporation and bylaws contain provisions 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 provisions permitting our stockholders to take action only at a duly called annual or special meeting of stockholders, which may only be called by the Chairman of the Board, the Chief Executive Officer or the Board of Directors. These provisions may have the effect of deterring hostile takeovers or delaying changes in control or change in our management.

 ITEM 1B. UNRESOLVED STAFF COMMENTS
 None.

 ITEM 1C. CYBERSECURITY
 Risk Management and Strategy
 We recognize the importance of assessing, identifying, and managing material risks to our Company associated with cybersecurity threats. These risks include, among other things, operational risks; intellectual property theft; fraud; extortion; harm to employees or customers; violation of privacy or security laws and other litigation and legal risk; and reputational risks. Our process for identifying and assessing material risks from cybersecurity threats operates alongside our broader enterprise risk management program process, covering other Company risks. As part of this process our enterprise risk professionals consult with Company subject matter experts to gather information necessary to identify cybersecurity risks, and evaluate their nature and severity, as well as identify mitigations and assess the impact of those mitigations on residual risk.
 We have implemented a variety of cybersecurity processes, technologies, and controls to aid in our efforts to identify, assess and manage such risks. Our approach includes: (1) an enterprise risk management program, which includes cybersecurity risks and is periodically refreshed; (2) security and privacy reviews designed to identify risks from many new features, software, and vendors; (3) a variety of privacy, cybersecurity, and incident response trainings and simulations, including regular phishing email simulations for all employees and contractors with access to corporate email systems; (4) tools designed to monitor our networks, systems and data for suspicious activity; (5) the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls; and (6) a third-party risk management process for cybersecurity threat risks associated with our use of third-party service providers, including service providers, suppliers, and vendors. We leverage industry standard security frameworks, including from the National Institute of Standards and Technology and the International Organization for Standardization, to evaluate our security controls and manage risk. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use these frameworks as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. We also carry insurance that provides protection against the potential losses arising from a cybersecurity incident.
 Our Incident Response Plan coordinates the activities we take to prepare for, detect, respond to and recover from cybersecurity incidents, which include processes to triage, assess severity, escalate, contain, investigate, and remediate the incident, as well as to comply with potentially applicable legal obligations and mitigate brand and reputational damage. The incident response team assesses the severity and priority of incidents on a rolling basis. If a cybersecurity incident is determined to be a material cybersecurity incident, our incident response processes define the steps to disclose such a material cybersecurity incident. Further, we conduct tabletop exercises to test and fortify the controls of our cybersecurity incident response program.
 We have not identified any risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. Please see the risk factor "Our business and operations could be adversely impacted in the event of a failure of information technology infrastructure." included as part of our risk factor disclosures under Item 1A of this Annual Report on Form 10-K, which disclosure is incorporated by reference herein.
 In the last three fiscal years, we have not experienced any material information security breach incidents and the expenses we have incurred from information security breach incidents were immaterial. This includes penalties and settlements, of which there were none.

 Governance
 Our Board of Directors (the Board) considers risks from cybersecurity threats as part of its risk oversight function and has delegated to the Audit Committee of the Board oversight of cybersecurity and other information technology risks. As set forth in its charter, our Audit Committee, comprised fully of independent directors, is responsible for oversight of risk, including cybersecurity and information security risks. Our Audit Committee has established a Cybersecurity Steering Committee consisting of three independent directors, Laura Black (who serves as Chair of the Cybersecurity Steering Committee), Douglas Gilstrap and Joanne Solomon, as well as our Chief Information Officer (CIO), our Chief Information Security Officer (CISO) and other members of our management representing a variety of teams and functions including legal, finance, and internal audit. Members of our Cybersecurity Steering Committee have work experience managing cybersecurity and information security risks, an understanding of the cybersecurity threat landscape and/or knowledge of emerging privacy risks.
 The purpose of the Cybersecurity Steering Committee is to oversee our compliance with reasonable and appropriate organizational, physical, administrative and technical measures designed to protect the confidentiality, integrity, availability, security and operations of our information technology systems, transactions, and data owned by us, by providing guidance and oversight of our information technology and cybersecurity program.
 The Cybersecurity Steering Committee generally meets on a quarterly basis and receives reports from the CISO and CIO of our cybersecurity and information security risk management and strategies, covering topics such as data security posture, results from third-party assessments, progress towards key initiatives, our incident response plan, and cybersecurity threat risks, incidents and developments. The Cybersecurity Steering Committee generally delivers reports and updates to the Audit Committee once a quarter.
 The Audit Committee or, at the Audit Committee's instruction, the Cybersecurity Steering Committee regularly briefs the full Board on these matters, and the Board receives regular updates on the status of the information security program, including but not limited to relevant cyber threats, roadmap and key initiative updates, and the identification and management of information security risks. Our full Board reviews cybersecurity-related opportunities as they relate to our business strategy, and cybersecurity-related matters are also factored into business continuity planning. We have protocols by which certain cybersecurity incidents are escalated within the Company and, where appropriate, reported to the Audit Committee.
 Our CISO, in coordination with our CIO and our Information Security team, is responsible for assessing and managing our material risks from cybersecurity threats and has primary responsibility for our overall cybersecurity risk management program and supervising both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our CISO has more than 10 years of experience in cybersecurity and information technology risk management, including at another large public company. He also has a degree in computer science. Our CIO has over 15 years of information technology experience, which includes managing information security systems, developing cybersecurity strategies and implementing effective information and cybersecurity programs.
 Our CISO and CIO supervise efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel, threat intelligence and other information obtained from governmental, public or private sources, and alerts and reports produced by security tools deployed in the IT environment, such as vulnerability assessments, penetration testing, and tabletop exercises.

 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 The following discussion and analysis summarizes the significant factors affecting our consolidated operating results, financial condition, liquidity and capital resources during the period ended June 28, 2025. Unless otherwise noted, all references herein for the years 2025, 2024 and 2023 represent the fiscal years ended June 28, 2025, June 29, 2024 and July 1, 2023, respectively. We intend for this discussion to provide the reader with information that will assist in understanding our financial statements, the changes in certain key items in those financial statements from year-to-year and the primary factors that accounted for those changes, as well as how certain accounting estimates affect our financial statements. Factors that could cause or contribute to these differences include those discussed below and in this Annual Report on Form 10-K, particularly in "Risk Factors" and "Forward-Looking Statements."
 This discussion should be read in conjunction with our consolidated financial statements and notes to the consolidated financial statements included in this Annual Report on Form 10-K that have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). Our actual results could differ materially from those discussed in the forward-looking statements.
 OVERVIEW
 VIAVI is a global provider of network test, monitoring and assurance solutions for telecommunications, cloud, enterprises, first responders, military, aerospace and critical infrastructure. VIAVI is also a leader in optical processing technologies for anti-counterfeiting, 3D sensing, aerospace, automotive and industrial applications.
 To serve our markets, we operate the following business segments:
 • Network and Service Enablement (NSE); and
 • Optical Security and Performance Products (OSP).
 Effective March 30, 2025, the Company realigned its segment reporting structure. As a result, the company's Network Enablement (NE) and Service Enablement (SE) business activities are now reported as a single operating and reportable segment, NSE. Recent acquisitions have reduced the SE segment revenue as a percentage of total VIAVI revenue. In addition, NE and SE are managed under common leadership, share many of the same customers and suppliers and operating expenses associated with the NSE business are not exclusively allocated to either NE or SE.
 During fiscal 2025, NSE revenue growth was mainly driven by strong demand primarily from the data center ecosystem for field, lab and production products for fiber and data center buildouts. We also saw growth in our aerospace and defense products. This was partially offset by a decline in spend for wireless and cable products by network equipment manufacturers (NEMs) and service providers. OSP performance slightly improved year-over-year with growth in our Anti-Counterfeiting and Other products as the industry's inventory levels normalized.
 Our financial results and long-term growth model will continue to be driven by revenue growth, non-GAAP operating income, non-GAAP operating margin, non-GAAP diluted earnings per share (EPS) and cash flow from operations. We believe these key operating metrics are useful to investors because management uses these metrics to assess the growth of our business and the effectiveness of our marketing and operational strategies.

 Proposed Acquisition
 On March 2, 2025, the Company entered into a purchase agreement to acquire Spirent Communications plc's (Spirent) high-speed ethernet and network security business lines and subsequently amended the agreement on May 28, 2025 to also purchase Spirent's channel emulation testing business (collectively, the HSE, network security and CE businesses) from Keysight Technologies, Inc. for our NSE segment. The total purchase consideration of $425 million will be paid at closing, subject to customary closing adjustments and conditions. The Company expects to fund this transaction with proceeds from a Term Loan B. The consummation of the acquisition is conditioned on regulatory approvals and is currently estimated to close by the end of September 2025.
 During the fourth quarter, we successfully priced and allocated the $600 million Term Loan B which will be used to fund the transaction at close and for general corporate purposes. The Term Loan B will close concurrently with the transaction.
 Looking Ahead to 2026
 As we look forward to fiscal 2026, we expect to continue to see stabilization and growth in many of our traditional businesses. Our long-term focus remains on executing against our strategic priorities to drive revenue and earnings growth, capture market share and continue to optimize our capital structure. We remain positive on our long-term growth drivers and will continue to focus on executing our strategic priorities over the long-term to:
 • Defend and consolidate leadership in core business segments;
 • Invest in secular trends to drive growth and expand total addressable market (TAM); and
 • Extend VIAVI technologies and platforms into lucrative adjacent markets and applications.
 The U.S. administration has implemented and could implement further broad-based, updated global tariffs and the situation continues to be dynamic and evolving. As we operate in this challenging environment, we are focused on continuing to deliver our products and services to our customers. Given our global business, tariffs will result in additional cost for us and our suppliers. We are analyzing ways to optimize our operations and supply chain strategies, control costs and implement pricing actions to reduce the impact from tariffs.

 FINANCIAL HIGHLIGHTS
 Our fiscal 2025 results included the following notable items:
 • Net revenue of $1.08 billion, up $83.9 million or 8.4% year-over-year
 • GAAP operating margin of 5.3%, up 320 bps year-over-year
 • Non-GAAP operating margin of 14.2%, up 270 bps year-over-year
 • GAAP diluted EPS of $0.15, up $0.27 or 225.0% year-over-year
 • Non-GAAP diluted EPS of $0.47, up $0.14 or 42.4% year-over-year
 In fiscal 2025, VIAVI began to experience stabilization and growth across many of our product segments. Net revenue of $1.08 billion was up $83.9 million compared to fiscal 2024, primarily from the data center ecosystem for field, lab and production products for fiber and data center buildouts, as well as growth in our aerospace and defense products, which was partially offset by a decline in spend by NEMs and service providers for wireless and cable products. Our acquisition of Inertial Labs contributed $25.2 million of net revenue in fiscal 2025. OSP performance slightly improved year-over-year with growth in our Anti-Counterfeiting and Other products.
 VIAVI's fiscal 2025 GAAP operating margin of 5.3% was up 320 bps compared to fiscal 2024 primarily due to higher volumes and favorable product mix, partially offset by the increase in intangible amortization. Non-GAAP operating margin of 14.2% increased 270 basis points primarily due to the increase in revenue, partially offset by higher operating expenses.
 GAAP diluted EPS of $0.15 increased $0.27 from fiscal 2024 primarily due to the increase in revenue. Non-GAAP diluted EPS of $0.47 increased $0.14 from fiscal 2024 also due to the increase in revenue.
 In fiscal 2025, we generated $89.8 million in operating cash flow and deployed $27.8 million or 2.6% of revenue towards capital expenditures. We also expended $121.7 million towards the acquisition of Inertial Labs and repurchased 2.0 million shares of our common stock for $16.4 million.

 Use of Non-GAAP (Adjusted) Financial Measures
 The Company provides non-GAAP operating income, non-GAAP operating margin, non-GAAP net income and non-GAAP EPS financial measures as supplemental information regarding the Company's operational performance and believes providing this additional information allows investors to see Company results through the eyes of management, and better to evaluate more clearly and consistently the Company's core operational performance and expenses and evaluate the efficacy of the methodology used by management to measure such performance. The Company uses the measures disclosed in this Annual Report on Form 10-K to evaluate the Company's historical and prospective financial performance, as well as its performance relative to its competitors. Specifically, management uses these items to further its own understanding of the Company's core operating performance, which the Company believes represents its performance in the ordinary, ongoing and customary course of its operations. Accordingly, management excludes from core operating performance items such as those relating to certain purchase price accounting adjustments, amortization of acquisition related intangibles, amortization expense related to acquisition related inventory step-up, stock-based compensation, legal settlements, restructuring, changes in fair value of contingent consideration liabilities, certain investing and acquisition related expenses and other activities and income tax expenses or benefits that management believes are not reflective of such ordinary, ongoing and core operating activities. The non-GAAP adjustments are outlined below.
 Cost of revenues, costs of research and development and costs of selling, general and administrative: The Company's GAAP presentation of gross margin and operating expenses may include (i) additional depreciation and amortization from changes in estimated useful life and the write-down of certain property, plant and equipment and intangibles, (ii) charges such as severance, benefits and outplacement costs related to restructuring plans with a specific and defined term, (iii) costs for facilities not required for ongoing operations, and costs related to the relocation of certain equipment from these facilities and/or contract manufacturer facilities, (iv) stock-based compensation, (v) amortization expense related to acquired intangibles, (vi) amortization expense related to acquisition related inventory step-up, (vii) changes in fair value of contingent consideration liabilities, (viii) acquisition related transaction and integration costs related to acquired entities, (ix) litigation and legal settlements and (x) other charges unrelated to our core operating performance comprised mainly of other costs and contingencies unrelated to current and future operations, including transformational initiatives such as the implementation of simplified automated processes, site consolidations and reorganizations. The Company excludes these items in calculating non-GAAP operating margin, non-GAAP net income and non-GAAP EPS.
 Non-cash interest expense and other expense: The Company excludes certain investing expenses, including accretion of debt discount, and other non-cash activities that management believes are not reflective of such ordinary, ongoing and core operating activities, when calculating non-GAAP net income and non-GAAP EPS.
 Income tax expense or benefit: The Company excludes certain non-cash tax expense or benefit items, such as (i) the utilization of net operating losses (NOLs) where valuation allowances were released, (ii) intra-period tax allocation benefit and (iii) the tax effect for amortization of non-tax deductible intangible assets, in calculating non-GAAP net income and non-GAAP EPS.
 Non-GAAP financial measures are not in accordance with, preferable to, or an alternative for, generally accepted accounting principles in the United States. The GAAP measure most directly comparable to non-GAAP operating income is operating income. The GAAP measure most directly comparable to non-GAAP operating margin is operating margin. The GAAP measure most directly comparable to non-GAAP net income is net income. The GAAP measure most directly comparable to non-GAAP EPS is earnings per share.

 Foreign Currency Impact on Results of Operations
 While the majority of our net revenue and operating expenses are denominated in U.S. dollar, a portion of our international operations are denominated in currencies other than the U.S. dollar. Changes in foreign exchange rates may significantly affect revenue and expenses. While we use foreign currency hedging contracts to mitigate some foreign currency exchange risk, these activities are limited in the protection that they provide us and can themselves result in losses. We have presented below "constant dollar" comparisons of our net sales and operating expenses, which exclude the impact of currency exchange rate fluctuations. Constant dollar net revenue and operating expenses are non-GAAP financial measures, which is information derived from consolidated financial information but not presented in our financial statements prepared in accordance with U.S. GAAP. Our management believes these non-GAAP measures, when considered in conjunction with the corresponding U.S. GAAP measures, may facilitate a better understanding of changes in net revenue and operating expenses. While management believes that these non-GAAP financial measures provide useful supplemental information, such adjusted results are not intended to replace our GAAP financial results and should be read in conjunction with those GAAP results.
 The Results of Operations are presented in accordance with U.S. GAAP and not using constant dollars. If currency exchange rates had been constant in fiscal 2025 and 2024, our consolidated net revenue in "constant dollars" would have increased from fiscal 2024 to fiscal 2025 by an additional $3.3 million, or 0.3% of net revenue, which primarily impacted our NSE segment. The impact of foreign currency fluctuations on net revenue was not indicative of the impact on net income due to the offsetting foreign currency impact on operating costs and expenses. If currency exchange rates had been constant in fiscal 2025 and 2024, our consolidated operating expenses in "constant dollars" would have increased from fiscal 2024 to fiscal 2025 by an additional $0.1 million.
 Refer to Item 7A "Qualitative and Quantitative Disclosures about Market Risk" of this Annual Report on Form 10-K for further details on foreign currency instruments and our related risk management strategies.

 Net Revenue
 Revenue from our service offerings exceeds 10% of our total consolidated net revenue and is presented separately in our Consolidated Statements of Operations. Service revenue primarily consists of maintenance and support, extended warranty, professional services and post-contract support in addition to other services such as calibration and repair services. When evaluating the performance of our segments, management focuses on total net revenue, gross profit and operating income and not the product or service categories. Consequently, the following discussion of business segment performance focuses on total net revenue, gross profit and operating income consistent with our approach for managing the business.
 Net revenue increased $83.9 million, or 8.4%, during fiscal 2025 when compared to fiscal 2024. This increase was primarily from the data center ecosystem for field, lab and production products for fiber and data center buildouts, as well as growth in our aerospace and defense products ($25.2 million contributed by our acquisition of Inertial Labs), which was partially offset by a decline in spend by NEMs and service providers for wireless and cable products. OSP performance slightly improved year-over-year driven by Anti-Counterfeiting and Other products.
 Product revenues increased $77.2 million, or 9.2%, during fiscal 2025 when compared to fiscal 2024, driven by volume increases in NSE and OSP.
 Service revenues increased $6.7 million, or 4.0%, during fiscal 2025 when compared to fiscal 2024, driven by a volume increase in NSE.

 Going forward, we expect to continue to encounter a number of industry and market risks and uncertainties. For example, uncertainty around the timing of our customers' procurement decisions on infrastructure maintenance and upgrades and decisions on new infrastructure investments or uncertainty about speed of adoption of 5G technology at a commercially viable scale. This may limit our visibility, and consequently, our ability to predict future revenue, seasonality, profitability and general financial performance, which could create period-over-period variability in our financial measures and present foreign exchange rate risks. The recent global tariffs implemented could increase our costs and impact our business.
 We cannot predict when or to what extent these uncertainties will be resolved. Our revenues, profitability and general financial performance may also be affected by: (a) pricing pressures due to, among other things, a highly concentrated customer base, increasing competition, particularly from Asia-based competitors and a general commoditization trend for certain products; (b) strategic execution challenges arising from competition with larger and more well-resourced competitors; (c) product mix variability in our markets, which affects revenue and gross margin; (d) fluctuations in customer buying patterns, which cause demand, revenue and profitability volatility; (e) the current trend of communication industry consolidation, which is expected to continue, that directly affects our NSE customer base and adds additional risk and uncertainty to our financial and business projections; (f) the impact of ongoing global trade policies, tariffs and sanctions; and (g) regulatory or economic developments and/or technology challenges that slow or change the rate of adoption of 5G, 3D sensing and other emerging secular technologies and platforms.

 Revenue by Region
 We operate in three geographic regions, including the Americas, Asia-Pacific and Europe Middle East and Africa (EMEA). Net revenue is assigned to the geographic region and country where our product is initially shipped. For example, certain customers may request shipment of our product to a contract manufacturer in one country, which may differ from the location of their end customers.

 Net revenue from customers outside the Americas for fiscal 2025, represented 60.8% of net revenue, a decrease of 0.1 percentage points year-over-year. We expect revenue from customers outside of the United States to continue to be an important part of our overall net revenue and an increasing focus for net revenue growth opportunities.

 Amortization of Acquired Technologies (Cost of revenues)
 Amortization of acquired technologies within Cost of revenues for fiscal 2025 increased $5.7 million, or 41.3%, to $19.5 million from $13.8 million in fiscal 2024. This increase is primarily due to the amortization of intangibles acquired through Inertial Labs, partially offset by certain intangibles becoming fully amortized.
 Gross Margin
 Gross margin in fiscal 2025 declined 0.3 percentage points to 57.3% from 57.6% in fiscal 2024. This decrease was primarily driven by the increase in amortization of intangibles and amortization of acquisition related inventory step-up, partially offset by higher volume and favorable product mix.
 As discussed in more detail under "Net Revenue" above, we sell products in certain markets that are consolidating, undergoing product, architectural and business model transitions, have high customer concentrations, are highly competitive (increasingly due to Asia-Pacific-based competition), are price sensitive and/or are affected by customer seasonal and mix variant buying patterns. We expect these factors to continue to result in variability of our gross margin.

 Research and Development
 Research and Development (R&D) expense increased $6.8 million, or 3.4%, during fiscal 2025 compared to fiscal 2024. This increase was primarily due to higher variable expenses and incremental cost from the acquisition of Inertial Labs, partially offset by a one-time R&D tax credit catch-up. As a percentage of net revenue, R&D decreased 0.9 percentage points during fiscal 2025 when compared to fiscal 2024.
 We believe that continuing our investments in R&D is critical to attaining our strategic objectives. We plan to continue to invest in R&D and new products that will further differentiate us in the marketplace.

 Selling, General and Administrative
 Selling, General and Administrative (SG&A) expense increased $16.1 million, or 4.8%, in fiscal 2025 compared to fiscal 2024. This increase was primarily due to higher variable expenses, higher acquisition and integration related charges and higher stock-based compensation. As a percentage of net revenue, SG&A decreased 1.1 percentage points in fiscal 2025 when compared to 2024.
 We intend to continue to focus on reducing our SG&A expense as a percentage of net revenue. However, we have in the recent past experienced, and may continue to experience in the future, certain charges unrelated to our core operating performance, such as acquisitions and integration related expenses and litigation expenses, which could increase our SG&A expense and potentially impact our profitability expectations in any particular quarter.
 Amortization of Other Intangibles (Operating expenses)
 Amortization of intangibles within Operating expenses for fiscal 2025 decreased $1.5 million, or 23.8%, to $4.8 million from $6.3 million in fiscal 2024. This decrease is primarily due to certain intangible assets becoming fully amortized, partially offset by amortization of intangibles acquired through Inertial Labs.

 Restructuring
 The Company's restructuring events are primarily intended to reduce costs, consolidate operations, integrate various acquisitions, streamline product manufacturing and address market conditions.
 During the fourth quarter of fiscal 2024, management approved a restructuring and workforce reduction plan (the Fiscal 2024 Plan) across various functions intended to improve operational efficiencies and better align the Company's workforce with current business needs. The Company expects approximately 7% of its global workforce to be affected, impacting both segments and corporate functions. We estimate annualized gross cost savings of approximately $25.0 million excluding any one-time charges as a result of the restructuring activities initiated under the Fiscal 2024 Plan. The Company anticipates the Fiscal 2024 Plan to be substantially complete by the end of the second quarter of fiscal 2026.
 The restructuring and workforce reduction plan, initiated in the second quarter of fiscal 2023 (the Fiscal 2023 Plan) across various functions to better align the Company's workforce with current business needs and strategic growth opportunities, was completed in the first quarter of fiscal 2025. The Fiscal 2023 Plan affected approximately 5% of the Company's workforce and resulted in an estimated annualized gross cost savings of approximately $25.0 million excluding any one-time charges.
 As of June 28, 2025, our total restructuring accrual was $3.5 million. During fiscal 2025, we recorded restructuring charges of $0.9 million related to the Fiscal 2024 Plan and a benefit of $0.2 million related to the Fiscal 2023 Plan. During fiscal 2024, we recorded charges of $14.8 million related to the Fiscal 2024 Plan and a benefit of $1.2 million related to the Fiscal 2023 Plan. During fiscal 2023, we recorded restructuring charges of $12.1 million related to the Fiscal 2023 Plan. Restructuring charges consisting of severance, benefit and outplacement costs were recorded to the Restructuring and related charges line within our Consolidated Statements of Operations.
 We estimate future cash payments of $3.5 million under the Fiscal 2024 Plan, funded by operating cash flow.
 Refer to "Note 13. Restructuring and Related Charges" under Item 8 of this Annual Report on Form 10-K for more information.

 Loss on Convertible Note Modification
 During fiscal 2023, the Company exchanged $127.5 million principal value of its 1.00% Senior Convertible Notes due 2024 for $132.0 million principal value of its 1.625% Senior Convertible Notes due 2026 and issued $118.0 million principal value of its 1.625% Senior Convertible Notes due 2026 for cash. The Company incurred $4.2 million of issuance costs related to this exchange, of which $2.2 million of the issuance costs were recorded as Loss on convertible note modification in the Consolidated Statements of Operations. The remaining issuance costs of $2.0 million were capitalized within Long-term debt (as a contra-balance) on the Consolidated Balance Sheets and are being amortized as an adjustment to interest expense on a straight-line basis until maturity.
 Interest and Other Income, Net
 Interest and other income, net was $11.1 million in fiscal 2025 as compared to $21.7 million in fiscal 2024. This $10.6 million decrease was primarily driven by a legal settlement in our favor in the amount of $7.3 million in fiscal 2024 and a decrease in interest income due to lower cash balances and lower yields compared to fiscal 2024.

 Interest Expense
 Interest expense decreased $0.9 million, or 2.9%, during fiscal 2025 compared to fiscal 2024. This decrease was primarily driven by lower outstanding debt when compared to fiscal 2024.

 Provision for Income Tax
 We recorded an income tax provision of $4.4 million for fiscal 2025. The expected tax provision derived by applying the federal statutory rate to our income before income taxes for fiscal 2025 differed from the income tax expense recorded primarily due to valuation allowances in addition to withholding taxes, foreign tax rates higher than the federal statutory rate and the U.S. inclusion of foreign earnings.
 Based on a jurisdiction-by-jurisdiction review of anticipated future income and due to the continued economic uncertainty in the industry, management has determined that in the U.S., it is more likely than not that our net deferred tax assets will not be realized. During fiscal 2025, the valuation allowance for deferred tax assets decreased by $69.7 million, which was primarily due to the increase in the deferred tax liability that resulted from the acquisition of Inertial Labs and its intangible assets, and the expiration of federal NOLs in the U.S.
 The decrease in income tax provision of $33.0 million or 88.2% during fiscal 2025 was due primarily to a $25.0 million release of valuation allowance related to our acquisition of Inertial Labs and a $7.5 million release of state income tax reserves due to the lapse in the statute of limitations.
 We are routinely subject to various federal, state and foreign audits by taxing authorities. We believe that adequate amounts have been provided for any adjustments that may result from these examinations.
 On July 4, 2025, the One Big Beautiful Bill Act (OBBBA), which includes a broad range of tax reform provisions, was signed into law in the United States. The effect of OBBBA will be recorded in the first quarter of fiscal 2026, as a change in tax law is accounted for in the period of enactment. We are currently evaluating the provisions of OBBBA, however we currently do not expect the OBBBA to have a material impact on our annual effective tax rate in fiscal 2026.

 Network and Service Enablement
 NSE net revenue increased $74.6 million, or 10.6% during fiscal 2025 when compared to fiscal 2024. This increase was primarily driven by higher volume in Lab and Production, Aerospace and Defense ($25.2 million contributed by our acquisition of Inertial Labs), partially offset by lower volume in Wireless.
 NSE gross margin increased by 0.2 percentage points during fiscal 2025 to 62.8% from 62.6% in fiscal 2024. This increase was primarily due to higher volume and favorable product mix.
 NSE operating margin increased by 4.3 percentage points during fiscal 2025 to 5.4% from 1.1% in fiscal 2024, primarily driven by higher volume and a one-time R&D tax credit catch-up.

 OSP net revenue increased $9.3 million, or 3.1%, during fiscal 2025 when compared to fiscal 2024. This increase was primarily driven by higher Anti-Counterfeiting and Other revenues, partially offset by a decrease in 3D sensing revenue.
 OSP gross margin increased by 1.2 percentage point during fiscal 2025 to 53.1% from 51.9% in fiscal 2024 primarily due to higher volume.
 OSP operating margin increased by 0.6 percentage points during fiscal 2025 to 36.5% from 35.9% in fiscal 2024, primarily due to the aforementioned increase in gross margin.

 Liquidity and Capital Resources
 We believe our existing liquidity and sources of liquidity, namely operating cash flows, credit facility capacity and access to capital markets, will continue to be adequate to meet our liquidity needs, including but not limited to, contractual obligations, working capital and capital expenditure requirements, financing strategic initiatives, funding debt maturities and executing purchases under our share repurchase program over the next twelve months and beyond. However, there are a number of factors that could positively or negatively impact our liquidity position, including:
 • Global economic conditions which affect demand for our products and services and impact the financial stability of our suppliers and customers;
 • The pending close of our acquisition of Spirent's HSE, network security and CE businesses and the related Term Loan B, which has been priced and allocated, with funding contingent upon closing;
 • Changes in accounts receivable, inventory or other operating assets and liabilities which affect our working capital;
 • Increase in capital expenditure to support the revenue growth opportunity of our business;
 • Changes in customer payment terms and patterns, which typically results in customers delaying payments or negotiating favorable payment terms to manage their own liquidity positions;
 • Timing of payments to our suppliers;
 • Factoring or sale of accounts receivable;
 • Volatility in fixed income and credit markets which impact the liquidity and valuation of our investment portfolios;
 • Volatility in credit markets that impact our ability to obtain additional financing on favorable terms or at all;
 • Volatility in foreign exchange markets which impacts our financial results;
 • Possible investments or acquisitions of complementary businesses, products or technologies;
 • Principal payment obligations of our 1.625% Senior Convertible Notes due 2026, and our 3.75% Senior Notes due 2029 (together the "Notes") and covenants that restrict our debt level and credit facility capacity;
 • Issuance or repurchase of debt which may include open market purchases of our 2026 Notes and/or 2029 Notes prior to their maturity;
 • Issuance or repurchase of our common stock or other equity securities;
 • Challenges in repatriating funds from certain foreign jurisdictions;
 • Factors beyond our control that may impact timing of and/or appropriation of government funding for certain of our strategic research and development programs;
 • Potential funding of pension liabilities either voluntarily or as required by law or regulation;
 • Compliance with covenants and other terms and conditions related to our financing arrangements; and
 • The risks and uncertainties detailed under Item 1A "Risk Factors" section of this Annual Report on Form 10-K.

 Cash and Cash Equivalents and Short-Term Investments
 Our cash and cash equivalents and short-term investments consist mainly of investments in institutional money market funds and short-term deposits at major global financial institutions. Our strategy is focused on capital preservation and supporting our liquidity requirements that meet high credit quality standards, as specified in our investment policy approved by the Audit Committee of our Board of Directors. Our investments in debt securities and marketable equity securities are primarily classified as available for sale or trading assets and are recorded at fair value. The cost of securities sold is based on the specific identification method. Unrealized gains and losses on available-for-sale investments are recorded as Other comprehensive income (loss) and are reported as a separate component of stockholders' equity. As of June 28, 2025, U.S. subsidiaries owned approximately 23.7% of our cash and cash equivalents, short-term investments and restricted cash.
 As of June 28, 2025, the majority of our cash investments have maturities of 90 days or less and are of high credit quality. Nonetheless we could realize investment losses under adverse market conditions. During the twelve months ended June 28, 2025, we have not realized material investment losses but can provide no assurance that the value or the liquidity of our investments will not be impacted by adverse conditions in the financial markets. In addition, we maintain cash balances in operating accounts with third-party financial institutions. These balances in the U.S. may exceed the Federal Deposit Insurance Corporation (FDIC) insurance limits. While we monitor the cash balances in our operating accounts and adjust as appropriate, these cash balances could be impacted if the underlying financial institutions fail.
 Senior Secured Asset-Based Revolving Credit Facility
 On December 30, 2021, we entered into a credit agreement (the Credit Agreement) with Wells Fargo Bank, National Association (Wells Fargo) as administrative agent and other lender related parties. The Credit Agreement provides for a senior secured asset-based revolving credit facility in a maximum aggregate amount of $300.0 million, which matures on December 30, 2026. The Credit Agreement also provides that, under certain circumstances, we may increase the aggregate amount of revolving commitments thereunder by an aggregate amount of up to $100.0 million so long as certain conditions are met. The Company is currently considering reducing the commitment under the Senior Secured Asset-Based Revolving Credit Facility to $200 million to be in line with borrowing base capacity and extend the maturity.
 As of June 28, 2025, we had no borrowings under this facility and our available borrowing capacity was approximately $170.8 million, net of outstanding standby letters of credit of $4.4 million.
 Refer to "Note 11. Debt" under Item 8 of this Annual Report on Form 10-K for more information.
 Term Loan B
 In March 2025, we obtained commitments for a $425 million 7-year term loan facility the proceeds of which would be available, subject to customary conditions, to fund our pending acquisition of Spirent's HSE and network security business from Keysight Technologies, Inc. We subsequently marketed and upsized to a $600 million 7-year term loan facility and successfully allocated the loan to prospective lenders at an initial interest rate of SOFR+2.50% and an original issue price of 99.75%. The incremental $175 million is intended for general corporate purposes. The term loan funding, as upsized, remains subject to customary closing conditions and the satisfaction or waiver of all closing conditions to the pending acquisition.

 Cash Flows Year Ended June 28, 2025
 As of June 28, 2025, our combined balance of cash and cash equivalents and restricted cash decreased by $49.7 million to $432.1 million from a balance of $481.8 million as of June 29, 2024.
 Cash provided by operating activities was $89.8 million, consisting of net income of $34.8 million adjusted for non-cash charges (e.g., depreciation, amortization, stock-based compensation and other non-cash items), and changes in deferred tax balances which totaled $85.2 million, offset by changes in operating assets and liabilities that used $30.2 million. Changes in our operating assets and liabilities related primarily to an increase in accounts receivable of $34.1 million due to billings outpacing collections, a decrease in accrued expenses and other current and non-current liabilities of $13.5 million due primarily to restructuring payments, an increase in inventory of $7.5 million related to demand changes, a decrease in income taxes payable of $6.3 million and an increase in other current and non-current assets of $4.0 million. These were partially offset by an increase in accounts payable of $14.6 million driven by timing of purchases and related payments, an increase in accrued payroll and related expenses of $12.7 million due primarily to variable pay and an increase in deferred revenue of $7.9 million due to timing of support billings and project acceptances.
 Cash used in investing activities was $128.4 million, primarily resulting from $121.6 million used for the acquisition of Inertial Labs, $27.8 million used for capital expenditures and $3.0 million investment in a non-marketable equity security, partially offset by $18.9 million net maturities of short-term investments and $5.1 million proceeds from sales of assets.
 Cash used in financing activities was $23.6 million, primarily resulting from $16.4 million cash paid to repurchase common stock under our share repurchase program, $13.2 million in withholding tax payments on the vesting of restricted stock and performance-based awards, partially offset by $6.0 million in proceeds from the issuance of common stock under our employee stock purchase plan.

 Purchase obligations represent legally-binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements. Of the $160.7 million of purchase obligations as of June 28, 2025, $75.7 million are related to inventory and the other $85.0 million are non-inventory items.
 As of June 28, 2025, our other non-current liabilities primarily relate to asset retirement obligations, pension and financing obligations which are presented in various lines in the preceding table.

 Share Repurchase Program
 During fiscal 2025, we repurchased 2.0 million shares of our common stock outstanding for $16.4 million pursuant to our 2022 Share Repurchase Plan. As of June 28, 2025, the Company had remaining authorization of $198.4 million for future share repurchases under the 2022 Repurchase Plan.
 Refer to "Note 15. Stockholders Equity" under Item 8 of this Annual Report on Form 10-K for more information.

 Employee Defined Benefit Plans and Other Post-retirement Benefits
 We sponsor significant qualified and non-qualified pension plans for certain past and present employees in the U.K. and Germany. These plans have been closed to new participants and no additional service costs are being accrued, except for certain plans in Germany assumed in connection with an acquisition during fiscal 2010.
 As of June 28, 2025, the U.K. plan is fully funded. During each of fiscal 2025 and fiscal 2024, we contributed 1.0 million or approximately $1.3 million to the U.K. pension plan. These contributions allowed us to comply with regulatory funding requirements.
 As of June 28, 2025, our German pension plans, which were initially established as unfunded or "pay-as-you-go" plans, were underfunded by $59.6 million since the projected benefit obligation (PBO) exceeded the fair value of plan assets. We anticipate future annual outlays related to the German plans will approximate estimated future benefit payments. These future benefit payments have been estimated based on the same actuarial assumptions used to measure our PBO and currently are forecasted to range between $4.3 million and $5.9 million per annum.
 We also are responsible for the non-pension post-retirement benefit obligation assumed from a past acquisition with a liability of $0.3 million.
 Recently Issued Accounting Pronouncements
 Refer to "Note 2. Recently Issued Accounting Pronouncements" under Item 8 of this Annual Report on Form 10-K, regarding the effect of certain recent accounting pronouncements on our Consolidated Financial Statements.
 Critical Accounting Estimates
 Our Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities, net revenue and expenses, and the disclosure of contingent assets and liabilities. Our estimates are based on historical experience and assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We believe that the accounting estimates employed and the resulting balances are reasonable; however, actual results may differ from these estimates and such differences may be material. Refer to "Note 1. Basis of Presentation" under Item 8 of this Annual Report on Form 10-K, for a discussion of the estimates used in preparation of our Consolidated Financial Statements.
 For contingent purchase consideration, the fair value of such earn-out liabilities are generally determined using a Monte Carlo Simulation that includes significant unobservable inputs such as the projected revenues of the acquired business over the earn-out period. The fair value of contingent consideration liabilities is remeasured at each reporting period at the estimated fair value based on the inputs on the date of remeasurement. The estimates used to determine the fair value of the contingent consideration liability are subject to significant judgment and given the inherent uncertainties in making these estimates, actual results are likely to differ from the amounts originally recorded and could be materially different.
 For our Pension accounting, significant judgment is required in actuarial assumption used when establishing the discount rate for the net periodic cost and the PBO calculations. Changes in the discount rate impact the interest cost component of the net periodic benefit cost calculation and PBO due to the fact that the PBO is calculated on a net present value basis. Decreases in the discount rate will generally increase pre-tax cost, recognized expense and the PBO. Increases in the discount rate tend to have the opposite effect. We estimate a 50-basis point decrease or increase in the discount rate would cause a corresponding increase or decrease, respectively, in the PBO of approximately $4.0 million based upon data as of June 28, 2025.

 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 Foreign Exchange Risk
 We use foreign exchange forward contracts to hedge foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily certain short-term intercompany receivables and payables. Our foreign exchange forward contracts are accounted for as derivatives whereby the fair value of the contracts are reflected as other current assets or other current liabilities and the associated gains and losses are reflected in Interest and other income, net in the Consolidated Statements of Operations. Our hedging programs reduce, but do not eliminate, the impact of currency exchange rate movements. The gains and losses on those derivatives are expected to be offset by re-measurement gains and losses on the foreign currency denominated monetary assets and liabilities.
 As of June 28, 2025, we had forward contracts that were effectively closed but not settled with the counterparties by fiscal year end. Therefore, the fair value of these contracts of $4.9 million and $3.1 million is reflected as Prepayments and other current assets and Other current liabilities on the Consolidated Balance Sheets, respectively.
 The forward contracts outstanding and not effectively closed, with a term of less than 120 days, were transacted near fiscal year ends; therefore, the fair value of the contracts was minimal as of June 28, 2025 and June 29, 2024. As of June 28, 2025 and June 29, 2024, the notional amounts of the forward contracts that we held to purchase foreign currencies were $60.4 million and $81.9 million, respectively, and the notional amounts of forward contracts that we held to sell foreign currencies were $24.1 million and $26.8 million, respectively.
 The counterparties to these hedging transactions are creditworthy multinational banks. The risk of counterparty nonperformance associated with these contracts is not considered to be material. Notwithstanding our efforts to mitigate some foreign exchange risks, we do not hedge all of our foreign currency exposures, and there can be no assurances that our mitigating activities related to the exposures that we do hedge will adequately protect us against the risks associated with foreign currency fluctuations.
 Investments
 The majority of our investments have maturities of 90 days or less. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investments as a result of changes in interest rates. Changes in interest rates can affect the interest earned on our investments.
 We seek to mitigate the credit risk of investments by holding high-quality, investment-grade debt instruments. We also seek to mitigate marketability risk by holding only highly liquid securities with active secondary or resale markets. However, the investments may decline in value or marketability due to changes in perceived credit quality or changes in market conditions.
 As of June 28, 2025, the Company's short-term investments of $1.7 million were primarily related to the deferred compensation plan, of which $1.6 million was invested in equity securities.
 Debt
 The fair value of our 2029 Notes is subject to interest rate risk while the fair value of our 2026 Notes is subject to interest rate and market price risk due to the convertible feature of the Notes and other factors. Generally, the fair value of fixed interest rate debt will increase as interest rates fall and decrease as interest rates rise. The fair value of the 2026 Notes may also increase as the market price of our stock rises and decrease as the market price of our stock falls. Changes in interest rates and our stock price in the case of convertible notes affect the fair value of the Notes but does not impact our financial position, cash flows or results of operations.
 Based on quoted market prices, as of June 28, 2025, the fair value of the 2026 Notes was $252.0 million and the fair value of the 2029 Notes was $373.6 million. As of June 28, 2025, the carrying value of the 2026 Notes was $246.2 million and the carrying value of the 2029 Notes was $396.3 million. Refer to "Note 11. Debt" under Item 8 of this Annual Report on Form 10-K for more information.

 ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the Board of Directors and Stockholders of Viavi Solutions Inc.

 Opinions on the Financial Statements and Internal Control over Financial Reporting

 We have audited the accompanying consolidated balance sheets of Viavi Solutions Inc. and its subsidiaries (the "Company") as of June 28, 2025 and June 29, 2024, and the related consolidated statements of operations, of comprehensive income (loss), of stockholders' equity and of cash flows for each of the three years in the period ended June 28, 2025, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of June 28, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

 In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June 28, 2025 and June 29, 2024, and the results of its operations and its cash flows for each of the three years in the period ended June 28, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 28, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

 Basis for Opinions

 The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

 Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

 As described in Management's Report on Internal Control over Financial Reporting, management has excluded Inertial Labs, Inc. ("Inertial Labs") from its assessment of internal control over financial reporting as of June 28, 2025 because it was acquired by the Company in a purchase business combination during 2025. We have also excluded Inertial Labs from our audit of internal control over financial reporting. Inertial Labs is a wholly-owned subsidiary whose total assets and total revenues excluded from management's assessment and our audit of internal control over financial reporting represent 2.1% and 2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended June 28, 2025.

 Definition and Limitations of Internal Control over Financial Reporting

 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 Critical Audit Matters

 The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

 Revenue Recognition - Network and Service Enablement Reportable Segment

 As described in Notes 1 and 19 to the consolidated financial statements, the Company had $1,084.3 million of total net revenue for the year ended June 28, 2025, of which $776.6 million related to the Network and Service Enablement reportable segment. Revenue is recognized at the point in time control is transferred to the customer. For hardware sales, transfer of control to the customer typically occurs at the point the product is shipped or delivered to the customer's designated location. For software license sales, transfer of control to the customer typically occurs upon shipment, electronic delivery, or when the software is available for download by the customer. For sales of implementation service and solution contracts or in instances where software is sold along with essential installation services, transfer of control occurs and revenue is typically recognized upon customer acceptance.

 The principal consideration for our determination that performing procedures relating to revenue recognition for the Network and Service Enablement reportable segment is a critical audit matter is a high degree of auditor effort in performing procedures related to the Company's revenue recognition.

 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 revenue recognition process, including controls over the recognition of revenue for the Network and Service Enablement reportable segment. These procedures also included, among others, for the Network and Service Enablement reportable segment (i) testing the revenue recognized, on a sample basis, by obtaining and inspecting source documents, such as contracts, invoices, evidence of transfer of control, and payment receipts, and recalculating revenue recognized; (ii) confirming outstanding customer invoice balances as of June 28, 2025, on a sample basis, and, for confirmations not returned, obtaining and inspecting source documents, such as contracts, invoices, evidence of transfer of control, subsequent payment receipts, and other source documents to support collectability of outstanding customer invoice balances; (iii) testing the issuance of credit memos, on a sample basis, by obtaining and inspecting source documents, such as credit memos, original invoices, and re-issued invoices; and (iv) testing the timing of revenue recognition, on a sample basis, for revenue transactions that occurred near period end by obtaining and inspecting source documents, such as invoices, evidence of transfer of control, and payment receipts.

 Acquisition of Inertial Labs – Valuation of Contingent Consideration and Developed Technology Acquired

 As described in Notes 1 and 5 to the consolidated financial statements, on January 28, 2025, the Company completed the acquisition of Inertial Labs for total purchase consideration of $270.6 million. The total purchase consideration included contingent consideration of up to $175.0 million, payable upon the achievement of certain revenue targets. As of the acquisition date, the fair value of the contingent consideration was $116.2 million. The fair value of the contingent consideration is determined using a Monte Carlo model that includes significant unobservable inputs such as the projected revenues of the acquired business over the earn-out period. Of the acquired intangible assets, $102.0 million related to developed technology. Management valued the developed technology acquired using the multi-period excess earnings method under the income approach. Significant assumptions used in the discounted cash flow analysis include projected revenues, discount rate, and technology obsolescence rate.

 The principal considerations for our determination that performing procedures relating to the valuation of contingent consideration and developed technology in the acquisition of Inertial Labs is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the contingent consideration and developed technology acquired; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management's significant assumptions related to (a) projected revenues for the contingent consideration and (b) projected revenues, discount rate, and technology obsolescence rate for the developed technology acquired; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

 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 acquisition accounting, including controls over management's valuation of the contingent consideration and developed technology acquired. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management's process for developing the fair value estimate of the contingent consideration and developed technology acquired; (iii) evaluating the appropriateness of the Monte Carlo model and multi-period excess earnings method used by management; (iv) testing the completeness and accuracy of the underlying data used in the Monte Carlo model and multi-period excess earnings method; and (v) evaluating the reasonableness of the significant assumptions used by management related to (a) projected revenues for the contingent consideration and (b) projected revenues, discount rate, and technology obsolescence rate for the developed technology acquired. Evaluating management's assumptions related to the projected revenues for the contingent consideration and developed technology acquired involved considering (i) the current and past performance of the Inertial Labs business; (ii) the consistency with external market and industry data; and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the Monte Carlo model and multi-period excess earnings method and (ii) the reasonableness of the discount rate and technology obsolescence rate assumptions for the developed technology acquired.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 Note 1. Basis of Presentation
 Description of Business
 Viavi Solutions, Inc. (VIAVI, also referred to as the Company, we, our and us), is a global provider of network test, monitoring and assurance solutions for telecommunications, cloud, enterprises, first responders, military, aerospace and critical infrastructure. VIAVI is also a leader in optical processing technologies for anti-counterfeiting, 3D sensing, aerospace, automotive and industrial applications.
 The Company utilizes a 52-53 week fiscal year ending on the Saturday closest to June 30th. The Company's 2025, 2024 and 2023 fiscal years were 52-week years ending on June 28, 2025, June 29, 2024, and July 1, 2023, respectively.
 Principles of Consolidation
 The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.
 Use of Estimates
 The preparation of the Company's Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that effect the reported amount of assets and liabilities at the date of the financial statements, the reported amount of net revenue and expenses and the disclosure of commitments and contingencies during the reporting periods. Estimates are based on historical factors, current circumstances and the experience and judgment of management. Under changed conditions the Company's reported financial positions or results of operations may be materially impacted when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more readily available information.
 Cash and Cash Equivalents
 The Company considers highly liquid instruments such as treasury bills, commercial paper and other money market instruments with original maturities of 90 days or less at the time of purchase to be cash equivalents.
 Restricted Cash
 At June 28, 2025 and June 29, 2024, the Company's short-term restricted cash balances were $ 3.7 million and $ 5.0 million, respectively. The Company's long-term restricted cash balances, included in Other non-current assets on the Consolidated Balance Sheets, were $ 4.9 million and $ 5.5 million as of June 28, 2025 and June 29, 2024, respectively. These balances primarily include interest-bearing investments in bank deposit and money market funds which act as collateral supporting the issuance of standby letters of credit and performance bonds for the benefit of third parties. Refer to "Note 18. Commitments and Contingencies" for more information.

 Investments
 The Company's investments in debt securities are classified as available for sale investments, recorded at fair value. The cost of securities sold is based on the specific identification method. Unrealized gains and losses resulting from changes in fair value on available-for-sale investments, net of tax, are reported as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets.
 The Company periodically reviews investments in debt securities for impairment. If a debt security's fair value is below amortized cost and the Company either intends to sell the security or it is more likely than not that the Company will be required to sell the security before its anticipated recovery, the Company records an other-than-temporary impairment charge to current earnings for the entire amount of the impairment. If a debt security's fair value is below amortized cost and the Company does not expect to recover the entire amortized cost of the security, the Company separates the other-than-temporary impairment into: (i) the portion of the loss related to credit factors, or the credit loss portion; and, (ii) the portion of the loss that is not related to credit factors, or the non-credit loss portion. The credit loss portion is recorded as an allowance to credit loss through Interest and other income, net, in the Consolidated Statements of Operations and the non-credit loss portion is recorded as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets.
 The Company's investments also include fixed term deposits with interest earned recorded as a component of Interest and other income, net, in the Consolidated Statements of Operations.
 Equity Investments
 The Company accounts for investments in entities for which it does not have a controlling financial interest or majority voting interest but has a significant influence over operating and financial policies, if any, under the equity method of accounting. Earnings and losses from such investments are recorded as Equity investment earnings in the Consolidated Statements of Operations.
 Fair Value of Financial Instruments
 Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. There is an established hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. Observable inputs are inputs which market participants would use in valuing an asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs which reflect the assumptions market participants would use in valuing an asset or liability.
 The three levels of inputs that may be used to measure fair value are:
 • Level 1: includes financial instruments for which quoted market prices for identical instruments are available in active markets. Level 1 assets of the Company include money market funds, U.S. Treasury securities and marketable equity securities as they are traded with sufficient volume and frequency of transactions.
 • Level 2: includes financial instruments for which the valuations are based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities. Level 2 instruments of the Company include asset-backed securities, foreign currency forward contracts and debt. To estimate their fair value, the Company utilizes pricing models based on market data. The significant inputs for the valuation model usually include benchmark yields, reported trades, broker and dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, and industry and economic events.

 • Level 3: includes financial instruments for which fair value is derived from valuation-based inputs, that are unobservable and significant to the overall fair value measurement. As of June 28, 2025, the Company's Level 3 assets consist of an investment in a non-marketable equity security in a privately held company. We measure the non-marketable equity security under the Measurement Alternative at cost minus impairment, if any, adjusted for observable price changes in orderly transactions for an identical or similar investment in the same issuer. As of June 29, 2024, the Company did not hold any Level 3 investment securities. The Company's Level 3 liabilities as of June 28, 2025 and June 29, 2024 consist of contingent purchase consideration liabilities related to business acquisitions. The fair value of such earn-out liabilities are generally determined using a Monte Carlo Simulation that includes significant unobservable inputs such as the projected revenues of the acquired business over the earn-out period. The fair value of certain earn-out liabilities is derived using the estimated probability of success of achieving the earn-out milestones discounted to present value. The fair value of contingent consideration liabilities is remeasured at each reporting period at the estimated fair value based on the inputs on the date of remeasurement, with the change in fair value recognized as Selling, general and administrative (SG&A) expense in the Consolidated Statements of Operations.
 Inventories
 The Company's inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of net realizable value. On a quarterly basis, the Company assesses the value of its inventory and writes down those inventories determined to be obsolete or in excess of its forecasted usage to their market value. The Company's estimates of realizable value are based upon management analysis and assumptions including, but not limited to, forecasted sales levels by product, expected product life cycle, product development plans and future demand requirements. The Company's product line management personnel play a key role in its excess review process by providing updated sales forecasts, managing product transitions and working with manufacturing to minimize excess inventory. Differences between actual market conditions and customer demand to the Company's forecasts, may create favorable or unfavorable inventory positions, and may result in additional inventory write-downs or higher than expected income from operations. The Company's inventory amounts include material, labor and manufacturing overhead costs.
 Leases
 The Company determines if an arrangement is a lease or contains a lease at inception. Operating lease liabilities are recognized based on the present value of the remaining lease payments, discounted using the discount rate for the lease at the commencement date. If the rate implicit in the lease is not readily determinable for our operating leases, the Company uses an incremental borrowing rate based on information available at the commencement date to determine the present value of future lease payments. The lease term is the non-cancelable period of the lease and includes options to extend or terminate the lease when it is reasonably certain that an option will be exercised. Operating right-of-use (ROU) assets are recognized at commencement based on the amount of the initial measurement of the lease liability. Operating ROU assets also include any lease payments made prior to lease commencement and exclude lease incentives. Lease expense is recognized on a straight-line basis over the lease term.
 Operating ROU assets are included in Other non-current assets and lease liabilities are included in Other current liabilities and Other non-current liabilities on the Consolidated Balance Sheets. Lease and non-lease components for all leases are accounted for separately. The Company does not recognize ROU assets and lease liabilities for leases with a lease term of twelve months or less.

 Property, Plant and Equipment
 Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using a straight-line method, over the estimated useful lives of the assets: building and improvements 5 to 50 years; machinery and equipment 3 to 30 years; and furniture, fixtures, software and office equipment 2 to 10 years.
 Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful lives of the asset or the remaining lease term.
 Demonstration units are Company products used for demonstration purposes for existing and prospective customers and are amortized using the straight-line method. These assets are generally not intended to be sold and have an estimated useful life of 3 to 5 years.
 Costs related to software acquired, developed or modified solely to meet the Company's internal requirements and for which there are no substantive plans to market are capitalized in accordance with the authoritative guidance on accounting for the costs of computer software developed or obtained for internal use. Only costs incurred after the preliminary planning stage of the project and after management has authorized and committed funds to the project are eligible for capitalization. Costs capitalized for computer software developed or obtained for internal use are included in Property, plant and equipment, net, on the Consolidated Balance Sheets.
 Business Combinations
 The Company includes the results of operations of the businesses that it acquires from the acquisition date. In allocating the purchase price of a business combination, the Company records all assets acquired and liabilities assumed at fair value as of the date of acquisition, with the excess of the purchase price over the aggregate fair values recorded as goodwill. Additionally, any contingent consideration is recorded at fair value on the acquisition date and classified as a liability. Contingent consideration amounts expected to be paid within one year of the balance sheet date are included in Other current liabilities on the Consolidated Balance Sheets. Contingent consideration amounts expected to be paid more than one year after the balance sheet date are included in Other non-current liabilities on the Consolidated Balance Sheets.
 The Company determines the estimated fair values after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. The fair value assigned to identifiable intangible assets acquired is based on estimates and assumptions made by management at the time of the acquisition. The Company adjusts the preliminary purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as it obtains more information as to facts and circumstances existing as of the acquisition date.
 Acquisition related costs are recognized separately from the business combination and are expensed as incurred.

 Goodwill
 Goodwill represents the excess of the purchase price paid over the net fair value of assets acquired and liabilities assumed. The Company tests goodwill for impairment at the reporting unit level at least annually, during the fourth quarter of each fiscal year, or more frequently if events or changes in circumstances indicate that the asset may be impaired.
 The accounting guidance provides the Company with the option to perform a qualitative assessment to determine whether further impairment testing is necessary. The qualitative assessment considers events and circumstances that might indicate that a reporting unit's fair value is less than its carry amount. These events and circumstances include, macro-economic conditions, such as a significant adverse change in the Company's operating environment, industry or market considerations; entity-specific events such as increasing costs, declining financial performance, or loss of key personnel, or other events, such as the sale of a reporting unit, adverse regulatory developments or a sustained decrease in the Company's stock price.
 If it is determined, as a result of the qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative test is required. Otherwise, no further testing is required.
 Under the quantitative test, the Company compares the fair value of a reporting unit to its carrying value. If the estimated fair value exceeds book value, goodwill is considered not to be impaired. However, if the fair value of the reporting unit is less than book value, then goodwill will be impaired by the amount that the carrying amount exceeds the fair value, not to exceed the carrying amount of the goodwill.
 To estimate the fair value of each reporting unit, a combination of the income and market approach is used. The income approach uses discounted future cash flows in which sales, operating income and cash flow projections are based on assumptions driven by current economic conditions. Key assumptions used in the discounted future cash flow model include, but are not limited to, long-term annual growth rates, terminal growth rates, weighted average cost of capital and the Company's effective tax rate.
 The market approach utilizes the Guideline Public Company Method and Guideline Transaction Method to derive fair value. The Guideline Public Company Method determines the fair value of an entity based upon trading multiples calculated using market value of minority interests in publicly-traded companies that are similar to the subject company. The Guideline Transaction Method calculates the fair value of an entity by analyzing recent sales of comparable entities.
 Refer to "Note 9. Goodwill" for more information.
 Intangible Assets
 In connection with the Company's acquisitions, the Company generally recognizes assets for customer relationships, acquired developed technologies, patents, proprietary know-how, trade secrets, in-process research and development (IPR&D) and trademarks and trade names. Finite lived intangible assets are amortized using the straight-line method over the estimated economic useful lives of the assets, which is the period during which expected cash flows support the fair value of such intangible assets. Refer to "Note 10. Acquired Developed Technology and Other Intangibles" for more information.
 Long-lived Assets
 Long-lived assets, including intangible assets and property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of any asset or asset group may not be recoverable. Such an evaluation is performed at the lowest identifiable level of cash flows independent of other assets. An impairment loss would be recognized when estimated undiscounted future cash flows generated from the assets are less than their carrying amount. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset or asset group over its estimated fair value. Estimates of future cash flow require significant judgment based on anticipated future operating results, which are subject to variability and change.

 Pension and Other Post-retirement Benefits
 The funded status of the Company's retirement-related benefit plans is recognized on the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at fiscal year end, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (PBO) and for the non-pension post-retirement benefit plan the benefit obligation is the accumulated post-retirement benefit obligation (APBO). The PBO represents the actuarial present value of benefits expected to be paid upon its employees' retirement. The APBO represents the actuarial present value of post-retirement benefits attributed to employee services already rendered. Unfunded or partially funded plans, with the benefit obligation exceeding the fair value of plan assets, are aggregated and recorded as a retirement and non-pension post-retirement benefit obligation equal to this excess. The current portion of the retirement-related benefit obligation represents the actuarial present value of benefits payable in the next 12 months in excess of the fair value of plan assets, measured on a plan-by-plan basis. This liability is recorded in Other current liabilities on the Consolidated Balance Sheets.
 Net periodic pension cost is recorded in the Consolidated Statements of Operations and includes service cost, interest cost, expected return on plan assets, amortization of prior service cost or credit, and gains or losses previously recognized as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets. Service cost represents the actuarial present value of participant benefits attributed to services rendered by employees in the current year. Interest cost represents the time value of money cost associated with the passage of time. Gains or losses arise as a result of differences between actual experience and assumptions or as a result of changes in actuarial assumptions. Prior service cost or credit represents the cost of benefit improvements attributable to prior service granted in plan amendments. Gains or losses and prior service cost or credit not recognized as a component of net periodic pension cost in the Consolidated Statements of Operations are recognized as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets, net of tax. Those gains or losses and prior service cost or credit are subsequently recognized as a component of net periodic pension cost pursuant to the recognition and amortization provisions of the authoritative guidance.
 The measurement of the benefit obligation and net periodic pension cost is based on the Company's estimates and actuarial valuations provided by third-party actuaries and are approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. The Company evaluates these assumptions periodically but not less than annually. In estimating the expected return on plan assets, the Company considers historical returns on plan assets, diversification of plan investments, adjusted for forward-looking considerations, inflation assumptions and the impact of the active management of the plan's invested assets.
 The Company measures its benefit obligation and plan assets using the month-end date of June 30, which is closest to the Company's fiscal year-end.

 Concentration of Credit and Other Risks
 Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, restricted cash, trade receivables and foreign currency forward contracts. The Company's cash and cash equivalents and short-term investments are held in safekeeping by large, creditworthy financial institutions. The Company invests its excess cash primarily in institutional money market funds, short-term deposits and similar short duration high quality, investment grade instruments.
 The Company has established guidelines relative to credit ratings, diversification and maturities that seek to maintain the safety and liquidity of these investments. The Company's foreign exchange derivative instruments expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreements. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading such risk across several major financial institutions. Potential risk of loss with any one counterparty resulting from such risk is monitored by the Company on an ongoing basis.
 The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. When the Company becomes aware that a specific customer is unable to meet its financial obligations, the Company records a specific allowance to reflect the level of credit risk in the customer's outstanding receivable balance. In addition, the Company records additional allowances based on certain percentages of aged receivable balances. These percentages consider a variety of factors including, but not limited to, current economic trends, historical payment and bad debt write-off experience. The Company classifies bad debt expenses as SG&A expense in the Consolidated Statements of Operations.
 The Company is not able to predict changes in the financial stability of its customers. Any material changes in the financial status of any one customer or a group of customers could have a material adverse effect on the Company's results of operations and financial condition. Although such losses have been within management's expectations to date, there can be no assurance that such allowances will continue to be adequate. The Company has significant trade receivables concentrated in the telecommunications industry. While the Company's allowance for credit losses balance is based on historical loss experience along with anticipated economic trends, unanticipated financial instability in the telecommunications industry could lead to higher than anticipated losses.
 As of June 28, 2025 and June 29, 2024, there were no customer balances that represented 10% or more of the Company's total accounts receivable, net.
 During fiscal 2025, 2024 and 2023, one customer generated 10% or more of total net revenues. Refer to "Note 19. Operating Segments and Geographic Information" for more information.
 The Company relies on a limited number of suppliers and contract manufacturers for a number of key components and sub-assemblies contained in the Company's products.
 The Company generally uses a rolling twelve-month forecast based on anticipated product orders, customer forecasts, product order history and backlog to determine its materials requirements for any one period. Lead times for the parts and components that the Company orders may vary significantly and depend on factors such as the specific supplier, contract terms and demand for a component at any given time. If the forecast does not meet actual demand, the Company may have surplus or dearth of some materials and components, as well as excess inventory purchase commitments. The Company could experience reduced or delayed product shipments or incur additional inventory write-downs and cancellation charges or penalties, which may result in increased costs and have a material adverse impact on the Company's results of operations.

 Foreign Currency Forward Contracts
 The Company conducts its business and sells its products to customers primarily in North America, Europe, Asia and South America. In the normal course of business, the Company's financial position is routinely subject to market risks associated with foreign currency rate fluctuations due to balance sheet positions in foreign currencies. The Company evaluates foreign exchange risks and utilizes foreign currency forward contracts to reduce such risks, hedging the gains or losses generated by the re-measurement of significant foreign currency-denominated monetary assets and liabilities. The fair value of these contracts is reflected as other current assets or liabilities and the change in fair value of these foreign currency forward contracts is recorded as gain or loss in the Consolidated Statements of Operations as a component of Interest and other income, net. The gain or loss from the change in fair value of these foreign currency forward contracts largely offsets the change in fair value of the foreign currency denominated monetary assets or liabilities, which is also recorded as a component of Interest and other income, net in the Consolidated Statements of Operations.
 Foreign Currency Translation
 VIAVI transacts business in various foreign currencies. In general, the functional currency of our non-US subsidiaries is the country's local currency. Consequently, the assets and liabilities of non-U.S. subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded as a component of Accumulated other comprehensive loss on the Consolidated Balance Sheets. Income and expense accounts are translated at exchange rates from the prior month end, which are deemed to approximate the exchange rate when the income and expense is recognized. Gains and losses from re-measurement of monetary assets and liabilities that are denominated in currencies other than the respective functional currencies are included in the Consolidated Statements of Operations as a component of Interest and other income, net.
 Revenue Recognition
 The Company derives revenue from a diverse portfolio of network solutions and optical technology products and services, as follows:
 • Products: Network and Service Enablement (NSE) products include instruments, microprobes and perpetual software licenses that support the development, production, maintenance and optimization of network systems. The Company's Optical Security and Performance (OSP) products include proprietary pigments used for optical security and optical filters used in commercial, government and 3D sensing applications.
 • Services: The Company also offers a range of product support and professional services, primarily in the NSE segment, designed to comprehensively address customer requirements. These include repair, calibration, extended warranty, software support, technical assistance, training and consulting services. Implementation services provided in conjunction with hardware or software solution projects include sale of the products along with project management, set-up and installation.
 Steps of revenue recognition
 The Company accounts for revenue in accordance with ASC 606: Revenue from Contracts with Customers, in which the following five steps are applied to recognize revenue:
 1.Identify the contract with a customer: Generally, the Company considers customer purchase orders which, in some cases are governed by master sales or other purchase agreements, to be the customer contract. All of the following criteria must be met before the Company considers an agreement to qualify as a contract with a customer under the revenue standard: (i) it must be approved by all parties; (ii) each party's rights regarding the goods and services to be transferred can be identified; (iii) the payment terms for the goods and services can be identified; (iv) the customer has the ability and intent to pay and collection of substantially all of the consideration is probable; and, (v) the agreement has commercial substance. The Company utilizes judgment to determine the customer's ability and intent to pay, which is based upon various factors including the customer's historical payment experience or credit and financial information and credit risk management measures implemented by the Company.

 2.Identify the performance obligations in the contract: The Company assesses whether each promised good or service is distinct for the purpose of identifying the various performance obligations in each contract. Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer; and, (ii) the Company's promise to transfer the good or service to the customer is separately identifiable or distinct from other promises in the contract. The Company's performance obligations consist of a variety of products and services offerings, which include networking equipment; proprietary pigment, optical filters, proprietary software licenses; support and maintenance, which includes software and hardware support that extends beyond the Company's standard warranties; installation, professional and implementation services, and training.
 Identifying and evaluating whether products and services are considered distinct performance obligations may require significant judgment particularly in NSE due to the nature of the product and service offerings. The Company may enter into contracts that involve a significant level of integration and interdependency between a software license and installation services. Judgment may be required to determine whether the software license is considered distinct in the context of the contract and accounted for separately, or not distinct in the context of the contract and accounted for together with the installation service.
 3.Determine the transaction price: Transaction price reflects the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to the customer. The Company's contracts may include terms that could cause variability in the transaction price including rebates, sales returns, market incentives and volume discounts. Variable consideration is generally accounted for at the portfolio level and estimated based on historical information. If a contract includes a variable amount, the price adjustments are estimated at contract inception. In both cases, estimates are updated at the end of each reporting period as additional information becomes available.
 4.Allocate the transaction price to performance obligations in the contract: If the contract contains a single performance obligation, the entire transaction price is allocated to that performance obligation. Many of the Company's contracts include multiple performance obligations with a combination of distinct products and services, maintenance and support, professional services and/or training. Contracts may also include rights or options to acquire future products and/or services, which are accounted for as separate performance obligations by the Company, only if the right or option provides the customer with a material right that it would not receive without entering into the contract. For contracts with multiple performance obligations, the Company allocates the total transaction value to each distinct performance obligation based on relative standalone selling price (SSP). Judgment is required to determine the SSP for each distinct performance obligation. The best evidence of SSP is the observable price of a good or service when the Company sells that good or service separately under similar circumstances to similar customers. If a directly observable price is not available, the SSP must be estimated based on multiple factors including, but not limited to, historical pricing practices, internal costs and profit objectives, as well as overall market conditions.
 5.Recognize revenue when (or as) performance obligations are satisfied: Revenue is recognized at the point in time control is transferred to the customer. For hardware sales, transfer of control to the customer typically occurs at the point the product is shipped or delivered to the customer's designated location. For software license sales, transfer of control to the customer typically occurs upon shipment, electronic delivery, or when the software is available for download by the customer. For sales of implementation service and solution contracts or in instances where software is sold along with essential installation services, transfer of control occurs and revenue is typically recognized upon customer acceptance. In certain instances, acceptance is deemed to have occurred if all acceptance provisions lapse, or if the Company has evidence that all acceptance provisions will be, or have been, satisfied. For fixed-price support and extended warranty contracts, or certain software arrangements which provide customers with a right to access over a discrete period, control is deemed to transfer over time and revenue is recognized on a straight-line basis over the contract term due to the stand-ready nature of the performance obligation. Revenue from hardware repairs and calibration services outside of an extended warranty or support contract is recognized at the time of completion of the related service. For other professional services or time-based labor contracts, revenue is recognized as the Company performs the services and the customers receive and/or consume the benefits.

 Revenue policy and practical expedients
 The following policy and practical expedient elections have been made by the Company under the revenue standard:
 • Revenue-based taxes as assessed by governmental authorities have been excluded from the measurement of transaction price.
 • Shipping and handling activities performed after the customer obtains control of the good are treated as activities to fulfill the promise (cost of fulfillment). Therefore, the Company does not evaluate whether the shipping and handling activities are promised services.
 • Incremental costs of obtaining contracts that would have been recognized within one year or less are recognized as an expense when incurred. These costs are included in SG&A expense in the Consolidated Statements of Operations. The costs of obtaining contracts where the amortization period for recognition of the expense is beyond a year are capitalized and recognized over the revenue recognition period of the original contract.
 • The portfolio approach is used for certain types of variable consideration for contracts with similar characteristics. The methodology is used when the effects on the financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts within that portfolio.
 • If at contract inception, the expected period between the transfer of promised goods or services and payment is within one year or less, the Company forgoes adjustment for the impact of significant financing component for the contract.
 Disaggregation of Revenue
 The Company's revenue is presented on a disaggregated basis in the Consolidated Statements of Operations and in "Note 19. Operating Segments and Geographic Information." This information includes a break-out of product and service revenue, revenue from reportable segments and revenue from each of the three geographic regions in which we operate.
 Warranty
 The Company provides reserves for the estimated costs of product warranties at the time revenue is recognized. Warranty cost estimates are based on historical experience of known product failure rates, use of materials to repair or replace defective products, and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.
 Shipping and Handling Costs
 The Company records costs related to shipping and handling of revenue in cost of sales for all periods presented.
 Advertising Expense
 The Company expenses advertising costs as incurred. Advertising costs totaled $ 2.0 million, $ 1.3 million and $ 2.6 million in fiscal 2025, 2024 and 2023, respectively.
 Research and Development Expense
 Costs related to research and development (R&D) primarily consist of labor and benefits, supplies, facilities, consulting and outside service fees. The authoritative guidance allows for capitalization of software development costs incurred after a product's technological feasibility has been established until the product is available for general release to the public. The Company believes its software development process is completed concurrent with the establishment of technological feasibility. As such, software development costs have been expensed as incurred.

 Government Assistance
 From time to time, the Company will receive government assistance in the form of grants and tax credits from government agencies in certain jurisdictions in which it operates. U.S. GAAP does not have specific accounting guidance covering agreements between government and business entities. The Company applies International Accounting Standards 20 (IAS 20), Accounting for Government Grants and Disclosure of Government Assistance, by analogy when accounting for government assistance. Under IAS 20, grants are recognized when there is reasonable assurance the conditions of the grant will be met and the grant will be received. After initial recognition, government assistance is recognized in a manner consistent with the manner in which the Company recognizes the underlying costs in the Consolidated Statement of Operations for which the grant is intended to compensate. Government assistance related to assets will generally be deducted from the asset's carrying value.
 Stock-Based Compensation
 The Company's stock-based compensation includes a combination of time-based restricted stock awards and performance-based awards, stock options, and an Employee Stock Purchase Plan (ESPP).
 Restricted stock awards are granted without an exercise price and are converted to shares immediately upon vesting. When converted into shares upon vesting, shares equivalent in value to the minimum withholding taxes liability on the vested shares are withheld by the Company for the payment of such taxes. Time-based restricted stock awards will generally vest in annual installments over a period of three to four years subject to the employees' continuing service to the Company.
 The Company's performance-based awards may include performance conditions, market conditions, time-based service conditions or a combination thereof and are generally expected to vest over one to four years. The actual number of shares awarded upon vesting of performance-based grants may vary from the target shares depending upon the achievement of the relevant performance or market-based conditions. The shares attained over target upon vesting for performance-based awards are reflected as awards granted during the period.
 The Company estimates the fair value of ESPP and stock options purchase rights using the Black-Scholes Merton (BSM) option-pricing model. This option-pricing model requires the input of assumptions, including the award's expected life and the price volatility of the underlying stock.
 The Company does not apply expected forfeiture rate and accounts for forfeitures as they occur. The total fair value of the equity awards is recorded on a straight-line basis, over the requisite service period of the awards for each separate vesting period of the award, except for certain performance-based awards which are amortized based upon the graded vesting method.

 Income Taxes
 In accordance with the authoritative guidance on accounting for income taxes, the Company recognizes income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for future tax consequences of events that have been recognized in the Company's Consolidated Financial Statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law and the effects of future changes in tax laws or rates are not anticipated.
 The authoritative guidance provides for recognition of deferred tax assets if the realization of such deferred tax assets is more likely than not to occur based on an evaluation of both positive and negative evidence and the relative weight of the evidence. With the exception of certain international jurisdictions, the Company has determined that at this time it is more likely than not that deferred tax assets attributable to the remaining jurisdictions will not be realized, primarily due to uncertainties related to its ability to utilize its net operating loss carryforwards before they expire. Accordingly, the Company has established a valuation allowance for such deferred tax assets. If there is a change in the Company's ability to realize its deferred tax assets for which a valuation allowance has been established, then its tax provision may decrease in the period in which it determines that realization is more likely than not. Likewise, if the Company determines that it is not more likely than not that its deferred tax assets will be realized, then a valuation allowance may be established for such deferred tax assets and the Company's tax provision may increase in the period in which the Company makes the determination.
 The authoritative guidance on accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Additionally, it provides guidance on recognition, classification, and disclosure of tax positions. The Company is subject to income tax audits by the respective tax authorities in the jurisdictions in which it operates. The determination of tax liabilities in each of these jurisdictions requires the interpretation and application of complex and sometimes uncertain tax laws and regulations. The Company recognizes liabilities based on its estimate of whether, and the extent to which, additional tax liabilities are more likely than not. If the Company ultimately determines that the payment of such a liability is not necessary, then it reverses the liability and recognizes a tax benefit during the period it is determined no longer necessary.
 The recognition and measurement of current taxes payable or refundable and deferred tax assets and liabilities requires that the Company make certain estimates and judgments. Changes to these estimates or a change in judgment may have a material impact on the Company's tax provision in a future period.
 Restructuring Accrual
 In accordance with authoritative guidance on accounting for costs associated with exit or disposal activities, generally costs associated with restructuring activities are recognized when they are incurred. A liability for post-employment benefits for workforce reductions related to restructuring activities is recorded when payment is probable, and the amount is reasonably estimable. The Company continually evaluates the adequacy of the remaining liabilities under its restructuring initiatives. Although the Company believes that these estimates accurately reflect the costs of its restructuring plans, actual results may differ, thereby requiring the Company to record additional liabilities or reverse a portion of existing liabilities.

 Contingencies
 The Company is subject to various potential loss contingencies arising in the ordinary course of business. In determining a loss contingency, the Company considers the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss. An estimated loss is accrued when it is probable that an asset has been impaired, a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required.
 Contingent liabilities include contingent consideration in connection with the Company's acquisitions, which represent earn-out payments and is recognized at fair value on the acquisition date and is remeasured each reporting period with subsequent adjustments recognized in SG&A expense in the Consolidated Statements of Operations. While the Company believes the estimates and assumptions are reasonable, there is significant judgment and uncertainty involved.
 Asset Retirement Obligations
 Asset retirement obligations (ARO) are legal obligations associated with the retirement of long-lived assets pertaining to leasehold improvements. These liabilities are initially recorded at fair value and the related asset retirement costs are capitalized by increasing the asset carrying value and ARO by the same amount. Asset retirement costs are subsequently depreciated over the useful lives of the related assets. Subsequent to initial recognition, the Company records period-to-period changes in the ARO liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows.

 Note 2. Recently Issued Accounting Pronouncements
 Recent Accounting Pronouncements Adopted
 In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2023-07, Improvements to Reportable Segment Disclosures (Topic 280), to improve reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses. The amendments in this update require public entities to disclose significant segment expenses included within segment profit and loss that are regularly provided to the Company's Chief Executive Officer as the Company's Chief Operating Decision Maker (CODM). This guidance is effective for fiscal 2025 for the Company. The Company adopted this guidance in the fourth quarter of fiscal 2025. See "Note 19. Operating Segments and Geographic Information" for the segment disclosure applying the guidance of ASU 2023-07, including retrospective application to all periods presented.
 In November 2024, the FASB issued ASU 2024-04, Debt-Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion or extinguishment of convertible debt. This guidance is effective for fiscal years beginning after December 15, 2025 (fiscal 2027 for the Company), and interim periods within those annual reporting periods, with early and retrospective adoption permitted. The Company adopted this guidance in the fourth quarter of fiscal 2025 on a prospective basis, which did not have an impact on the Company's Consolidated Financial Statements. We will assess future impact, if any, in subsequent periods.
 Accounting Pronouncements Issued But Not Yet Adopted
 In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of income statement expenses for public business entities. The objective of this guidance is to improve the disclosures about a public business entity's expenses and address requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization and depletion) in commonly presented expense captions such as Cost of revenues, R&D and SG&A. This guidance is effective for fiscal years beginning after December 15, 2026 (fiscal 2028 for the Company), and interim periods within fiscal years beginning after December 15, 2027, with early and retrospective adoption permitted. The Company is evaluating the impact of adopting this new accounting guidance on its Consolidated Financial Statements.
 In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740), to enhance the transparency and decision usefulness of income tax disclosures through changes to the rate reconciliation and income taxes paid information. This guidance is effective for fiscal years beginning after December 15, 2024 (fiscal 2026 for the Company), with early and retrospective adoption permitted. The Company is evaluating the impact of adopting this new accounting guidance on its Consolidated Financial Statements.
 In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements-Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments clarify or improve disclosure and presentation requirements on various disclosure areas, including the statement of cash flows, earnings per share, debt, equity and derivatives. The amendments will align the requirements in the FASB Accounting Standards Codification (ASC) with the SEC's regulations. The amendments in this ASU will be effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC, and will not be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. This ASU is not expected to have a material impact on our Consolidated Financial Statements or related disclosures.
 We reviewed all other accounting pronouncements issued during fiscal 2025 and concluded that they were not applicable to the Company.

 Note 3. Earnings Per Share
 Basic net income (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. If dilutive, the effect of outstanding ESPP purchase rights, restricted stock units (RSUs), performance-based stock units (PSUs), market-based stock units (MSUs), stock options and Senior Convertible Notes is reflected in diluted net income (loss) per share by application of the treasury stock method and/or the if-converted method, as applicable. The calculation of diluted net income (loss) per share excludes all anti-dilutive common shares.

 Note 5. Acquisitions
 Inertial Labs, Inc.
 On January 28, 2025, the Company acquired all of the equity of Inertial Labs, Inc. (Inertial Labs), a privately held company which specializes in resilient positioning, navigation and timing (PNT) solutions for aerospace, defense and industrial applications. The acquisition enables the Company to further broaden its solutions offering into the rapidly developing PNT landscape.
 The total purchase consideration included approximately $ 134.4 million paid in cash at closing and additional contingent consideration of up to $ 175.0 million, payable upon the achievement of certain revenue targets over the course of a four-year period beginning in January 2025. As of the acquisition date, the fair value of the contingent consideration was $ 116.2 million. The net cash paid for the acquisition, with purchase price adjustment, was $ 121.6 million, which reflects the cash paid less cash acquired of $ 16.5 million. From the contingent consideration of $ 175.0 million, $ 3.4 million shall be set aside for the payment of retention bonuses over the four-year earn-out period to key personnel and service providers, contingent on continued service to the Company. Any forfeited amount will be removed from the retention bonus pool and re-distributed to the shareholders of Inertial Labs upon the achievement of the earn-out targets. The portion of the estimated fair value of the earn-out liability allocated to the retention bonuses will be accounted for as post combination expense over the requisite service period.
 The cash consideration paid at closing included an escrow payment of $ 1.0 million subject to final net working capital adjustments. The Company paid $ 3.7 million in our fourth fiscal quarter of 2025 comprised of the net working capital holdback of $ 3.0 million and $ 0.7 million of the purchase price adjustment of $ 1.4 million. The remainder of the purchase price adjustment of $ 0.7 million and refund of prepaid tax of $ 0.6 million is expected to be paid in fiscal 2026. In addition, the Company held back $ 15.0 million for indemnity claims. The acquisition met the definition of a business and has been accounted for in accordance with the authoritative guidance on business combinations; therefore, the tangible and intangible assets acquired and liabilities assumed were recorded at fair value on the acquisition date. Acquisition related costs incurred were approximately $ 11.7 million and have been recorded within SG&A expense in the Consolidated Statements of Operations. These costs included $ 9.5 million in transaction bonuses that were paid at closing to key personnel and service providers of Inertial Labs.

 The total purchase consideration was allocated to tangible and intangible assets acquired and liabilities assumed based on the preliminary fair value on the acquisition date. The following table presents the preliminary allocation of the purchase price ( in millions):

 Developed technology relates to products used for PNT solutions for aerospace, defense and industrial applications. The Company valued the developed technology using the multi-period excess earnings method under the income approach. This method reflects the present value of the projected cash flows that are expected to be generated by the developed technology. Significant assumptions used in the discounted cash flow analysis include (i) projected revenues, (ii) discount rate, and (iii) technology obsolescence rate.

 Goodwill represents the excess of the preliminary estimated purchase consideration over the preliminary estimates of the fair value of the net tangible and intangible assets acquired and has been allocated to the NSE segment. Goodwill is primarily attributable to expected synergies in the acquired technologies that may be leveraged by the Company in future PNT offerings. None of the goodwill recognized is deductible for U.S. income tax purposes.
 The Company has included the financial results of Inertial Labs in its Consolidated Financial Statements from the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to the Consolidated Statements of Operations.

 Jackson Labs Technologies, LLC
 On October 5, 2022, the Company acquired all of the equity of Jackson Labs Technologies, LLC (Jackson Labs), a privately held company which specializes in PNT solutions for critical infrastructure serving both military and civilian applications. The acquisition enables the Company to broaden its solutions offering into the rapidly developing PNT landscape.
 The total purchase consideration included approximately $ 49.9 million paid in cash at closing and additional contingent consideration of up to $ 117.0 million for which future cash payments are dependent on the achievement of certain operational and revenue targets over the course of a three-year period beginning in January 2023. The cash consideration paid at closing included escrow payments of $ 5.0 million for indemnity holdback and $ 2.0 million subject to final cash and net working capital adjustments. The acquisition has been accounted for in accordance with the authoritative guidance on business combinations; therefore, the tangible and intangible assets acquired and liabilities assumed were recorded at fair value on the acquisition date. In connection with this acquisition, the Company recorded approximately $ 48.3 million of goodwill and $ 30.6 million of developed technology and other intangibles. The acquired developed technology and other intangible assets are being amortized over their estimated useful lives ranging from one to six years. Acquisition related costs incurred were approximately $ 0.8 million and have been recorded within SG&A expense in the Consolidated Statements of Operations.
 Goodwill represents the excess of the purchase consideration over the fair value of the net tangible and intangible assets acquired and has been allocated to the NSE segment. Goodwill is primarily attributable to expected synergies in the acquired technologies that may be leveraged by the Company in future PNT offerings. The goodwill was deductible for U.S. income tax purposes in the year of acquisition.
 The Company has included the financial results of Jackson Labs in its Consolidated Financial Statements from the date of acquisition. Pro forma results of operations have not been presented because the effect of the acquisition was not material to the Consolidated Statements of Operations.

 Note 6. Balance Sheet and Other Details
 Contract Balances
 Unbilled Receivables: The Company records a receivable when an unconditional right to consideration exists and transfer of control has occurred, such that only the passage of time is required before payment of consideration is due. Timing of revenue recognition may differ from the timing of customer invoicing. Payment terms vary based on product or service offerings and payment is generally required within 30 to 90 days from date of invoicing. Certain performance obligations may require payment before delivery of the service to the customer.
 Contract Assets: A Contract Asset is recognized when a conditional right to consideration exists and transfer of control has occurred. Contract Assets include fixed fee professional services, where the transfer of services has occurred in advance of the Company's right to invoice. Contract Assets, included in Accounts receivable, net, on the Consolidated Balance Sheets, are not material to the Consolidated Financial Statements. Contract Asset balances will fluctuate based upon the timing of transfer of services, billings and customers' acceptance of contractual milestones.
 Gross Receivables: Includes both billed and Unbilled Receivables/Contract Assets. As of June 28, 2025 and June 29, 2024, the Company had total Unbilled Receivables/Contract Assets of $ 14.1 million and $ 16.3 million, respectively.
 Deferred Revenue: Deferred revenue consists of contract liabilities primarily related to support, solution deployment services, software maintenance, product, professional services and training when the Company has a right to invoice or payments have been received and transfer of control has not occurred. Revenue is recognized on these items when the revenue recognition criteria are met, generally resulting in ratable recognition over the contract term.
 The Company also has short-term and long-term deferred revenue related to undelivered hardware and professional services, consisting of installations and consulting engagements, which are recognized as the Company's performance obligations under the contract are completed and accepted by the customer.

 (2) Revenue recognized during the period represents releases from the balance at the beginning of the period as well as releases from the following period quarter-end deferrals.
 (3) The long-term portion of deferred revenue is included as a component of Other non-current liabilities on the Consolidated Balance Sheets.
 Remaining Performance Obligations: Remaining performance obligations represent the aggregate amount of the transaction price allocated to performance obligations not delivered or are incomplete as of June 28, 2025. Remaining performance obligations include deferred revenue plus unbilled amounts not yet recorded. The aggregate amount of the transaction price allocated to remaining performance obligations does not include amounts owed under cancellable contracts where there is no substantive termination penalty.
 Remaining performance obligation estimates are subject to change and are affected by several factors, including terminations, changes in the scope of contracts, periodic revalidation, adjustments for revenue that has not materialized, and adjustments for currency.
 The value of the transaction price allocated to remaining performance obligations as of June 28, 2025 was $ 345.0 million. The Company expects to recognize 90 % of the remaining performance obligations as revenue within the next 12 months, and the residual thereafter.

 Note 7. Investments and Forward Contracts
 Short-Term Investments
 As of June 28, 2025, the Company's short-term investments of $ 1.7 million were primarily related to the deferred compensation plan, of which $ 1.6 million was invested in equity securities.
 As of June 29, 2024, the Company's short-term investments of $ 19.9 million were comprised of 30 -day term deposits of $ 18.4 million and trading securities related to the deferred compensation plan of $ 1.5 million, of which $ 1.4 million was invested in equity securities and $ 0.1 million was invested in debt securities.
 Trading securities are reported at fair value, with the unrealized gains or losses resulting from changes in fair value recognized in the Consolidated Statements of Operations as a component of Interest and other income, net.
 Strategic Investment
 During the first fiscal quarter of 2025, the Company invested $ 3.0 million in a non-marketable equity security in a privately held company. The investment is included in Other non-current assets on the Consolidated Balance Sheets and is classified as Level 3 within the fair value hierarchy.
 This investment is carried at cost and because the investment does not have a readily determinable fair value, it will be adjusted for changes resulting from observable price changes under the Measurement Alternative methodology. There were no impairments or adjustments to the carrying value for the year ended June 28, 2025.
 Equity Investment
 The Company acquired an equity interest in Sensorsan Sensor Teknolojileri Anonim Sirketi (Sensorsan), a privately held entity and owns 40 % percent of Sensorsan, through its acquisition of Inertial Labs.
 The Company accounts for its investment in Sensorsan under the equity method of accounting. Under the equity method, the Company recognizes income or loss from its pro-rata share of Sensorsan's net income or loss, which changes the carrying value of the Sensorsan investment.
 The Company's share of Sensorsan's net income for the period from acquisition date until June 28, 2025 was $ 0.6 million. As of June 28, 2025, the carrying value of the Company's investment in Sensorsan was $ 1.3 million, included in Other non-current assets on the Consolidated Balance Sheets. The Company sells certain products to Sensorsan. During the year ended June 28, 2025, revenue from sales to Sensorsan was $ 1.8 million and the accounts receivable balance was $ 1.4 million.

 Non-Designated Foreign Currency Forward Contracts
 The Company has foreign subsidiaries that operate and sell the Company's products in various markets around the world. As a result, the Company is exposed to foreign exchange risks. The Company utilizes foreign exchange forward contracts to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily certain short-term intercompany receivables and payables, and to reduce the volatility of earnings and cash flows related to foreign-currency transactions. The Company does not use these foreign currency forward contracts for trading purposes.
 As of June 28, 2025, the Company had forward contracts that were effectively closed but not settled with the counterparties by fiscal year end. Therefore, the fair value of these contracts of $ 4.9 million and $ 3.1 million is reflected as Prepayments and other current assets and Other current liabilities on the Consolidated Balance Sheets, respectively. As of June 29, 2024, the fair value of these contracts of $ 1.7 million and $ 1.5 million is reflected as Prepayments and other current assets and Other current liabilities on the Consolidated Balance Sheets, respectively.
 The forward contracts outstanding and not effectively closed, with a term of less than 120 days, were transacted near fiscal year ends; therefore, the fair value of the contracts was minimal as of June 28, 2025 and June 29, 2024. As of June 28, 2025 and June 29, 2024, the notional amounts of the forward contracts that the Company held to purchase foreign currencies were $ 60.4 million and $ 81.9 million, respectively, and the notional amounts of forward contracts the Company held to sell foreign currencies were $ 24.1 million and $ 26.8 million, respectively.
 The change in the fair value of these foreign currency forward contracts is recorded as a gain or loss in the Consolidated Statements of Operations as a component of Interest and other income, net. The cash flows related to the settlement of foreign currency forward contracts are classified as operating activities. The foreign exchange forward contracts incurred losses of $ 1.0 million and $ 0.7 million for the years ended June 28, 2025 and June 29, 2024, respectively.

 Impairment of Goodwill
 The Company tests goodwill at the reporting unit level for impairment annually, during the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that the asset may be impaired. As a result of the segment change during the fourth fiscal quarter of 2025 discussed in "Note 19. Operating Segments and Geographic Information,'' management performed a goodwill impairment analysis on the reporting units prior to and after the change and did not identify an impairment.
 No indications of impairment were identified under the qualitative assessment of goodwill impairment for fiscal years ending on June 28, 2025 and June 29, 2024.
 In fiscal 2023, the Company performed a quantitative assessment of goodwill impairment for all reporting units. Based on our testing during the fourth quarter of fiscal 2023, the fair value of each of the Company's reporting units was at least two times the carrying value, and therefore no impairment was identified.

 On March 6, 2023, the Company issued $ 250.0 million aggregate principal amount of 1.625 % Senior Convertible Notes due 2026 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company issued $ 132.0 million aggregate principal amount of the 2026 Notes to certain holders of the 1.00 % Senior Convertible Notes due 2024 (2024 Notes) in exchange for $ 127.5 million principal amount of the 2024 Notes (the Exchange Transaction) and issued and sold $ 118.0 million aggregate principal amount of the 2026 Notes in a private placement to accredited institutional buyers (the Subscription Transactions).
 The Exchange Transaction was accounted for as a modification. The $ 127.5 million principal of the 2024 Notes was reduced by $ 10.1 million, with offsetting increase to additional paid-in capital, to account for the increase in the fair value of the embedded conversion option in the modification. The increase in principal and coupon interest, along with the increased option value, totaled $ 14.6 million and is a direct reduction from the carrying amount of the debt on the Consolidated Balance Sheets. This amount will be accreted as an adjustment to interest expense on a straight-line basis and will accrete up to the full-face value of the 2026 Notes at maturity.
 The proceeds of the Subscription Transactions amounted to $ 113.8 million after issuance costs of $ 4.2 million. The exchange resulted in $ 2.2 million of the issuance costs recorded as Loss on convertible note modification in the Consolidated Statements of Operations. The remaining issuance costs of $ 2.0 million, as well as $ 0.3 million of unamortized costs carried over from the 2024 Notes at the exchange date were capitalized within Long-term debt (as a contra-balance) on the Consolidated Balance Sheets and will be amortized to interest expense using the straight-line method until maturity.
 The 2026 Notes are an unsecured obligation of the Company and bear interest at an annual rate of 1.625 %, payable semi-annually in arrears on March 15 and September 15 of each year, beginning September 15, 2023. The 2026 Notes mature on March 15, 2026 unless earlier converted, redeemed or repurchased.

 The 2026 Notes may be converted under certain circumstances, based on an initial conversion rate of 75.7963 shares (equivalent to an initial conversion price of approximately $ 13.19 per share) at the option of the holders into cash up to the principal amount, with the remaining amount converted into cash, shares of the Company's common stock, or a combination of cash and shares of the Company's common stock at the Company's election. The initial conversion price represents a 22.5 % premium to the closing price of the Company's common stock on the pricing date, March 1, 2023, which will be subject to customary anti-dilution adjustments.
 The 2026 Notes may be converted at any time on or prior to the close of business on the business day immediately preceding December 15, 2025, in multiples of $ 1,000 principal amount, at the option of the holder under the following circumstances:
 • On any date during any calendar quarter beginning after June 30, 2023 (and only during such calendar quarter) if the closing price of the Company's common stock was more than 130 % of the then current conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading-day period ending on the last trading day of the previous calendar quarter;
 • If the Company distributes to all or substantially all holders of its common stock rights or warrants (other than pursuant to a stockholder rights plan) entitling them to purchase, for a period of 45 calendar days or less, shares of VIAVI's common stock at a price less than the average closing sale price of VIAVI's common stock for the ten trading days preceding the declaration date for such distribution;
 • If the Company distributes to all or substantially all holders of its common stock, cash or other assets, debt securities or rights to purchase our securities (other than pursuant to a stockholder rights plan), at a per share value exceeding 10 % of the closing sale price of the Company's common stock on the trading day preceding the declaration date for such distribution;
 • If the Company is party to a specified transaction, a fundamental change or a make-whole fundamental change (each as defined in the indenture of the 2026 Notes);
 • During the five consecutive business-day period immediately following any ten consecutive trading-day period in which the trading price per $1,000 principal amount of the 2026 Notes for each day during such ten consecutive trading-day period was less than 98 % of the product of the closing sale price of VIAVI's common stock and the applicable conversion rate on such date; or
 • If the Company calls any or all of the 2026 Notes for Optional Redemption.
 During the periods from, and including, December 15, 2025 until the close of business on the business day immediately preceding March 15, 2026, holders may convert the 2026 Notes at any time regardless of the foregoing circumstances.
 Holders of the 2026 Notes may require the Company to purchase all or a portion of the 2026 Notes upon the occurrence of a fundamental change at a purchase price equal to 100 % of the principal amount of the 2026 Notes to be purchased, plus accrued and unpaid interest to, but excluding, the fundamental repurchase date.
 The Company may not redeem the 2026 Notes prior to March 20, 2025. The Company may redeem for cash all or part of the 2026 Notes, at its option, on or after March 20, 2025 if the closing price of the Company's common stock was at least 130 % of the then current conversion price for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides the redemption notice in accordance with the Indenture. If the Company redeems less than all the outstanding 2026 Notes, at least $ 75.0 million aggregate principal amount of 2026 Notes must be outstanding and not subject to redemption as of the relevant redemption notice date.
 The Indenture provides for customary events of default, including payment defaults, breaches of covenants, failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If an event of default occurs and is continuing, the principal amount of the 2026 Notes, plus accrued and unpaid interest, if any, may be declared immediately due and payable, subject to certain conditions set forth in the Indenture. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs.
 As of June 28, 2025, the expected remaining term of the 2026 Notes is 0.7 years.

 3.75 % Senior Notes (2029 Notes)
 On September 29, 2021, the Company issued $ 400.0 million aggregate principal amount of 3.75 % Senior Notes due 2029 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. In connection with the issuance of the 2029 Notes, the Company incurred $ 7.0 million of issuance costs. The debt issuance costs were capitalized and will be amortized to interest expense using the straight-line method until maturity. The 2029 Notes are an unsecured obligation of the Company and bear annual interest of 3.75 %, payable semi-annually in arrears on April 1 and October 1 of each year, beginning April 1, 2022. The 2029 Notes mature on October 1, 2029 unless earlier redeemed or repurchased. As of June 28, 2025, the expected remaining term of the 2029 Notes is 4.3 years.
 1.75 % Senior Convertible Notes (2023 Notes)

 In connection with the issuance of the 2023 Notes, the Company incurred $ 2.2 million of issuance costs. The debt issuance costs were capitalized and amortized to interest expense using the straight-line method from the issuance date through maturity on June 1, 2023.
 During fiscal 2022, the Company entered into separate privately-negotiated agreements with certain holders of the 2023 Notes, settling $ 156.9 million principal in exchange for an aggregate of 2.0 million shares of its common stock, par value $ 0.001 per share, and $ 168.5 million in cash. On June 1, 2023, the remaining 2023 Notes principal of $ 68.1 million was retired upon maturity.
 1.00 % Senior Convertible Notes (2024 Notes)
 On March 3, 2017, the Company issued $ 400.0 million aggregate principal amount of 1.00 % Senior Convertible Notes due 2024 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. On March 22, 2017, the Company issued an additional $ 60.0 million upon exercise of the over-allotment option of the initial purchasers. The total proceeds from the 2024 Notes amounted to $ 451.1 million after issuance costs of $ 8.9 million. The debt issuance costs were capitalized and amortized to interest expense using the straight-line method from the issuance date through maturity on March 1, 2024.

During fiscal 2023 the Exchange Transaction resulted in the reduction of $ 127.5 million principal of the 2024 Notes. On March 1, 2024, the Company converted two notes at the request of the respective note-holders and retired the remaining 2024 Notes principal of $ 96.4 million upon maturity.

 Senior Secured Asset-Based Revolving Credit Facility
 On December 30, 2021, we entered into a credit agreement (the Credit Agreement) with Wells Fargo Bank, National Association (Wells Fargo) as administrative agent, and other lender related parties. The Credit Agreement provides for a senior secured asset-based revolving credit facility in a maximum aggregate amount of $ 300 million, which matures on December 30, 2026. The Credit Agreement also provides that, under certain circumstances, the Company may increase the aggregate amount of revolving commitments thereunder by an aggregate amount of up to $ 100 million so long as certain conditions are met. The proceeds from the credit facility established under the Credit Agreement will be used for working capital and other general corporate purposes. The obligations under the Credit Agreement are secured by substantially all of the assets of the Company and those of its subsidiaries that are borrowers and guarantors under the Credit Agreement. The Company is currently considering reducing the commitment under the Senior Secured Asset-Based Revolving Credit Facility to $ 200 million to be in line with borrowing base capacity and extend the maturity.
 Amounts outstanding under the Credit Agreement accrue interest as follows: (i) if the amounts outstanding are denominated in U.S. Dollars, at a per annum rate equal to either, at the Company's election, Term Secured Overnight Financing Rate (SOFR) plus a margin of 1.35 % to 1.85 % per annum, or a specified base rate plus a margin of 0.25 % to 0.75 %, in each case, depending on the average excess availability under the facility, (ii) if the amounts outstanding are denominated in Sterling, at a per annum rate equal to the Sterling Overnight Interbank Average Rate (SONIA) plus a margin of 1.2825 % to 1.7825 %, depending on the average excess availability under the facility, (iii) if the amounts outstanding are denominated in Euros, at a per annum rate equal to the Euro Interbank Offered Rate plus a margin of 1.25 % to 1.75 %, depending on the average excess availability under the facility, or (iv) if the amounts outstanding are denominated in Canadian Dollars, at a per annum rate equal to either, at the Company's election, the adjusted Term Canadian Overnight Repo Rate Average (CORRA) plus a margin of 1.25 % to 1.75 %, or a specified base rate plus a margin of 0.25 % to 0.75 %, in each case, depending on the average excess availability under the facility.
 The covenants of the Credit Agreement include customary restrictive covenants that, among other things, restrict the Company's ability to incur additional indebtedness, grant liens and make certain acquisitions, investments, asset dispositions and restricted payments. In addition, the Credit Agreement contains certain financial covenants that require the Company to maintain a fixed charge coverage ratio of at least 1.00 to 1.00 if excess availability under the facility is less than the greater of 10 % of the lesser of maximum revolver amount and borrowing base and $ 20 million.
 As of June 28, 2025, we had no borrowings under this facility and our available borrowing capacity was approximately $ 170.8 million, net of outstanding standby letters of credit of $ 4.4 million.
 Term Loan B
 In March 2025, we obtained commitments for a $ 425 million 7-year term loan facility the proceeds of which would be available, subject to customary conditions, to fund our pending acquisition of Spirent's HSE and network security business from Keysight Technologies, Inc. We subsequently marketed and upsized to a $ 600 million 7-year term loan facility and successfully allocated the loan to prospective lenders at an initial interest rate of SOFR+ 2.50 % and an original issue price of 99.75 %. The incremental $ 175 million is intended for general corporate purposes. The term loan funding, as upsized, remains subject to customary closing conditions and the satisfaction or waiver of all closing conditions to the pending acquisition.

 As of June 28, 2025, the Company had federal, state and foreign tax net operating loss carryforwards of $ 1,218.6 million, $ 314.9 million and $ 470.5 million, respectively, and federal and state research tax credit carryforwards of $ 84.6 million and $ 55.2 million, respectively. The federal tax net operating loss carryforwards start to expire in fiscal 2026 and at various dates through 2038, if not utilized. The federal research tax credit carryforwards start to expire in fiscal 2026, and at various dates through fiscal 2045, if not utilized. The state tax net operating loss carryforwards start to expire in fiscal 2026 and at various dates through 2045, if not utilized. The state research tax credit starts to expire in fiscal 2026 but a majority of the state credits have an indefinite carryforward period. In addition, a portion of the foreign tax net operating loss and capital loss carryforwards have an indefinite carryforward period. Utilization of the tax net operating losses may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state and foreign provisions. Loss carryforward limitations may result in the expiration or reduced utilization of a portion of the Company's net operating losses.
 During fiscal 2024, the Company completed a series of planned internal transactions between subsidiaries within the group to optimize our ability to repatriate earnings back to the U.S. As a result of these transactions, the Company is able to reduce the amount of withholding tax that will be accrued on current and future earnings. The tax expense of these transactions was approximately $ 1.2 million.
 Foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries have not been provided on $ 19.2 million of undistributed earnings for certain foreign subsidiaries. The Company intends to reinvest these earnings indefinitely outside of the U.S. The Company estimates that an additional $ 1.9 million of foreign withholding taxes would have to be provided if these earnings were repatriated back to the U.S.
 The valuation allowance decreased by $ 69.7 million in fiscal 2025, decreased by $ 15.5 million in fiscal 2024, and increased by $ 30.7 million in fiscal 2023. The decrease during fiscal 2025 was primarily due to the increase in the deferred tax liability that resulted from the acquisition of Inertial Labs and the expiration of federal net operating losses (NOLs) in the U.S. The decrease during fiscal 2024 was primarily due to the amortization of intangibles assets and utilization of NOLs, offset by an increase in the capitalization of federal research expenditures in the U.S. The increase during fiscal 2023 was primarily due to the increase in capitalization of federal research expenditures in the U.S. This includes the effects of the mandatory capitalization and amortization of R&D expenses incurred in fiscal 2023, as required by the 2017 Tax Cuts and Jobs Act (Tax Act).

 The unrecognized tax benefits relate primarily to the allocations of revenue and costs among the Company's global operations and the validity of some U.S. tax credits. Included in the balance of unrecognized tax benefits at June 28, 2025 is $ 7.9 million of tax benefits that, if recognized, would impact the effective tax rate. Also included in the balance of unrecognized tax benefits at June 28, 2025 is $ 34.6 million of tax benefits that, if recognized, would result in adjustments to the valuation allowance.
 The Company's policy is to recognize accrued interest and penalties related to unrecognized tax benefits within the income tax provision. The amount of interest and penalties accrued as of June 28, 2025, June 29, 2024 and July 1, 2023 were approximately $ 3.4 million, $ 3.8 million, and $ 2.9 million, respectively. The timing and resolution of income tax examinations is uncertain, and the amounts ultimately paid, if any, upon resolution of issues raised by the taxing authorities may differ from the amounts accrued for each year. Although we do not expect that our balance of gross unrecognized tax benefits will change materially in the next 12 months, given the uncertainty in the development of ongoing income tax examinations, we are unable to estimate the full range of possible adjustments to this balance.
 The Company is routinely subject to various federal, state and foreign audits by taxing authorities. The Company believes that adequate amounts have been provided for any adjustments that may result from these examinations.

 Note 15. Stockholders' Equity
 Repurchase of Common Stock
 In September 2022, the Board of Directors authorized a new stock repurchase plan (2022 Repurchase Plan) of up to $ 300 million effective October 1, 2022 which remains in effect until the amount authorized has been fully repurchased or until suspension or termination of the program. Under the 2022 Repurchase Plan, the Company is authorized to repurchase shares through a variety of methods, including open market purchases, privately-negotiated transactions or otherwise in accordance with applicable federal securities laws, including through Rule 10b5-1 trading plans. The timing of repurchases under the plan will depend upon business and financial market conditions.
 During fiscal 2025, the Company repurchased 2.0 million shares of its common stock for $ 16.4 million under the 2022 Repurchase Plan. As of June 28, 2025, the Company had remaining authorization of $ 198.4 million for future share repurchases under the 2022 Repurchase Plan.

 The total purchase price of these repurchases was reflected as a decrease to common stock based on the stated par value per share with the remainder charged to accumulated deficit. All common shares repurchased during fiscal 2025, 2024 and 2023 have been canceled and retired.
 Preferred Stock
 The Company's Board of Directors has authority to issue up to 1,000,000 shares of undesignated preferred stock and to determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any wholly unissued shares of undesignated preferred stock and to fix the number of shares constituting any series and the designation of such series, without the consent of the Company's stockholders. The preferred stock could be issued with voting, liquidation, dividend and other rights superior to those of the holders of common stock. Subsequent issuance of any preferred stock by the Company's Board of Directors, under some circumstances, could have the effect of delaying, deferring or preventing a change in control.

 Note 16. Stock-Based Compensation
 Stock-Based Benefit Plans
 Stock Award Plans
 The Company's Amended and Restated 2003 Plan provides for the granting of stock options, stock appreciation rights (SARs), dividend equivalent rights, restricted stocks, RSUs, performance units and performance shares, the vesting of which may be time-based or upon satisfaction of performance criteria or other conditions.
 As of June 28, 2025, the Company had 10.2 million shares subject to Full Value Awards (defined below) issued and outstanding and 7.8 million shares of common stock available for grant under the Amended and Restated 2003 Plan.
 Employee Stock Purchase Plans
 The Company's ESPP provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll deductions and provides a discounted purchase price as well as a look-back period. The ESPP is structured as a qualified employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986. As of June 28, 2025, 5.9 million shares remained available for issuance. The ESPP, as amended, provides for a 15 % discount with a look-back period of six months.
 Full Value Awards
 The Company's stock-based compensation includes a combination of time-based RSUs and MSUs and PSUs. RSUs are granted without an exercise price and are converted to shares immediately upon vesting. When converted into shares upon vesting, shares equivalent in value to the minimum withholding taxes liability on the vested shares are withheld by the Company for the payment of such taxes. For performance-based awards, shares attained over target upon vesting are reflected as awards granted during the period.
 Time-based RSU awards will generally vest in annual installments over a period of three to four years subject to the employees' continuing service to the Company. The Company's performance-based MSU and PSU awards may include performance conditions, market conditions, time-based service conditions or a combination thereof and are generally expected to vest over one to four years. In addition, the actual number of shares awarded upon vesting of performance-based grants may vary from the target shares depending upon the achievement of the relevant performance or market-based conditions.

 Stock Option Activity
 During fiscal 2024, 1.2 million of stock options were exercised all of which have been fully amortized and recognized since before June 29, 2019. There were no stock options outstanding as of June 28, 2025.

 Employee Stock Purchase Plan Activity
 The expense related to the ESPP is recorded on a straight-line basis over the relevant subscription period. During fiscal 2025, the Company issued shares of 511,207 and 389,509 on January 31, 2025 and July 31, 2024, respectively, as part of the ESPP. As of June 28, 2025, there was $ 0.2 million of unrecognized stock-based compensation cost related to the ESPP that remains to be amortized. The cost will be recognized in the first quarter of fiscal 2026.
 Full Value Awards Activity

 (1) Performance Shares refer to the Company's MSU and PSU awards, where the actual number of shares awarded upon vesting may be higher or lower than the target amount depending on the achievement of the relevant market conditions and performance goal achievement. The majority of MSUs vest in equal annual installments over three to four years based on the attainment of certain total shareholder performance measures and the employee's continued service through the vest date. The aggregate grant-date fair value of MSUs granted during fiscal 2025, 2024 and 2023 was estimated to be $ 15.4 million, $ 13.4 million and $ 11.4 million, respectively, and was calculated using a Monte Carlo simulation. The Company did not grant any PSU awards in fiscal 2025, 2024 and 2023. PSU awards vest based on the attainment of certain performance measures and the employee's continued service through the vest date.
 As of June 28, 2025, $ 54.9 million of unrecognized stock-based compensation cost related to Full Value Awards remains to be amortized. That cost is expected to be recognized over the remaining amortization period of 1.6 years.

 Valuation Assumptions
 The Company estimates the fair value of time-based RSU awards based on the closing market price of the Company's common stock on the date of grant. In the case of PSUs that are performance-based awards without a market condition, the Company will estimate the fair value of the awards using a probability weighted model. In the case of MSUs or PSUs, that are performance-based awards and include a market condition, the Company will estimate the fair value of the awards using a combination of the closing market price of the Company's common stock on the grant date and the Monte Carlo simulation model. The weighted-average assumptions used to measure fair value of performance-based awards with a market condition were as follows:

 Volatility of common stock

 The Company did no t issue stock option grants during the fiscal years ended June 28, 2025, June 29, 2024 and July 1, 2023. The Company estimates the fair value of ESPP purchase rights using a BSM valuation model. The fair value is estimated on the date of grant using the BSM option valuation model with the following weighted-average assumptions:

 Expected Term: The Company's purchase right period is six months under the ESPP.
 Expected Volatility: The expected volatility for ESPP purchase rights was based on the historical volatility of its stock price with a similar expected term.
 Risk-Free Interest Rate: The Company bases the risk-free interest rate used in the BSM valuation method on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term.
 Expected Dividend: The BSM valuation model calls for a single expected dividend yield as an input. The Company has not paid and does not anticipate paying any dividends in the near future.

 Note 17. Employee Pension and Other Benefit Plans
 Employee 401(k) Plans
 The Company sponsors the Viavi Solutions 401(k) Plan (the 401(k) Plan), a defined contribution plan under ERISA, which provides retirement benefits for its eligible employees through tax deferred salary deductions. The 401(k) Plan allows employees to contribute up to 50 % of their annual compensation, with contributions limited to $ 23,500 in calendar year 2025 as set by the Internal Revenue Service.
 For all eligible employees, the Company offers a 401(k) Plan that provides a 100 % match of employees' contributions up to the first 3 % of annual compensation and 50 % match on the next 2 % of compensation. All matching contributions are made in cash and vest immediately. The Company's matching contributions to the 401(k) Plan were $ 5.2 million, $ 5.3 million and $ 5.4 million in fiscal 2025, 2024 and 2023, respectively.
 Employee Defined Benefit Plans
 The Company is responsible for a non-pension post-retirement benefit obligation assumed from a past acquisition, which is closed to new participants. As of June 28, 2025 and June 29, 2024, the liability balances related to the non-pension post-retirement benefit plan were $ 0.3 million. The liability balances were included in Other non-current liabilities on the Consolidated Balance Sheets.
 The Company sponsors significant qualified and non-qualified pension plans for certain past and present employees in the U.K. and Germany including the plan assumed in a prior acquisition. These pension plans have been closed to new participants and no additional service costs are being accrued, except for certain plans in Germany assumed in connection with an acquisition during fiscal 2010. Benefits are generally based upon years of service and compensation or stated amounts for each year of service. As of June 28, 2025, the U.K. plan was fully funded while the other plans were unfunded. The Company's policy for funded plans is to make contributions equal to or greater than the requirements prescribed by law or regulation. For unfunded plans, the Company pays the post-retirement benefits when due. Future estimated benefit payments are summarized under the Future Benefit Payments section below. No other required contributions are expected in fiscal 2026, but the Company, at its discretion, can make contributions to one or more of the defined benefit plans.
 In July 2024, the U.K. Court of Appeal upheld a ruling in the matter of Virgin Media Limited v NTL Pension Trustees II Limited, a decision that VIAVI was not a party to or involved in, that certain historical amendments for contracted out defined benefit schemes were invalid if they were not accompanied by the correct actuarial confirmation. In June 2025, Department for Work and Pensions announced that the government will introduce legislation to give affected pension schemes the ability to retrospectively obtain written actuarial confirmation that historic benefit changes met the necessary standards. The prospective legislation could significantly reduce the potential negative impact of the court decision in the Virgin Media case on U.K. pension schemes, including the Company's U.K pension scheme, as there would be an opportunity to pursue retrospective confirmation if necessary or applicable to validate historical amendments. No expected timeline of when the legislation will come out has been announced. The Company continues to monitor developments and assess potential impact for its U.K. pension scheme.
 The Company accounts for its obligations under these pension plans in accordance with the authoritative guidance which requires the Company to record its obligation to the participants, as well as the corresponding net periodic cost. The Company determines its obligation to the participants and its net periodic cost principally using actuarial valuations provided by third-party actuaries. The obligation the Company records on its Consolidated Balance Sheets is reflective of the total PBO and the fair value of plan assets.

 The following table presents the components of the net periodic benefit cost for the pension and benefits plans (in millions):

 During each of fiscal 2025 and fiscal 2024, the Company contributed 1.0 million or approximately $ 1.3 million to its U.K. pension plan. These contributions allowed the Company to comply with regulatory funding requirements.
 Assumptions
 Underlying both the calculation of the PBO and net periodic cost are actuarial valuations. These valuations use participant-specific information such as salary, age, years of service, and assumptions about interest rates, compensation increases and other factors. At a minimum, the Company evaluates these assumptions annually and makes changes as necessary.
 The discount rate reflects the estimated rate at which the pension benefits could be effectively settled. In developing the discount rate, the Company considered the yield available on an appropriate AA corporate bond index, adjusted to reflect the term of the scheme's liabilities as well as a yield curve model developed by the Company's actuaries.
 The expected return on assets was estimated by using the weighted average of the real expected long-term return (net of inflation) on the relevant classes of assets based on the target asset mix and adding the chosen inflation assumption.

 The following table summarizes the weighted average assumptions used to determine net periodic cost and benefit obligation for the Company's U.K. and German pension plans:

 Investment Policies and Strategies
 The Company's investment objectives for its funded pension plan are to ensure that there are sufficient assets available to pay out members' benefits as and when they arise and that, should the plan be discontinued at any point in time, there would be sufficient assets to meet the discontinuance liabilities.
 To achieve these objectives, the trustee of the U.K. pension plan is responsible for regularly monitoring the funding position and managing the risk by investing in assets expected to perform approximately in line with the liabilities and help minimize volatility in the funding position. The trustee invests in a range of frequently traded funds (pooled funds) rather than direct holdings in individual securities to maintain liquidity, achieve diversification and reduce the potential for risk concentration. The funded plan assets are managed by professional third-party investment managers.

 The Company's pension assets consist of multiple institutional funds (pension funds) of which the fair values are based on the quoted prices of the underlying securities. Pension funds are classified as Level 2 assets since such funds are not directly traded in active markets.
 Fixed income consists of several funds that invest primarily in index-linked Gilts (over 5 years), Gilts index (over 15 years), sterling-denominated investment grade corporate bonds and overseas government bonds.
 Equity / Other consisted of several funds that invested primarily in U.K. equities and other overseas equities as well as a small portion in liquid alternatives.

 Note 18. Commitments and Contingencies
 Royalty Payments
 The Company is obligated to make future minimum royalty payments of $ 0.2 million measured as of June 28, 2025 for the use of certain licensed technologies, which are expected to be paid through the third quarter of fiscal 2026.
 Purchase Obligations
 Purchase obligations of $ 160.7 million as of June 28, 2025, represent legally-binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements. Certain purchase orders allow the option to cancel, reschedule and adjust the requirements based on the Company's business needs prior to the delivery of the goods or performance of the services. Obligations to purchase inventory and other commitments are generally expected to be fulfilled within one year.
 The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for raw materials, packages and standard components. The Company generally purchases these single or limited source products through standard purchase orders or one-year supply agreements and has no significant long-term guaranteed supply agreements with such vendors. While the Company seeks to maintain a sufficient safety stock of such products and maintains on-going communications with its suppliers to guard against interruptions or cessation of supply, the Company's business and results of operations could be adversely affected by a stoppage or delay of supply, substitution of more expensive or less reliable parts, receipt of defective parts or contaminated materials, increases in the price of such supplies, or the Company's inability to obtain reduced pricing from its suppliers in response to competitive pressures.

 Financing Obligations
 On August 21, 2007, the Company entered into a sale and lease-back of certain buildings and land in Santa Rosa, California (the Santa Rosa Transactions), under which we leased back certain buildings. The net cash proceeds received from the transaction were $ 32.2 million. The lease terms range from a one-year lease with multiple renewal options to a ten-year lease with two five-year renewal options. These buildings did not qualify for sale and lease back accounting due to various forms of continuing involvement and, as a result, they were accounted for as financing transactions.
 In August 2012 and May 2019, the Company entered into two lease amendments to extend the term of the lease to August 31, 2032 with a ten-year renewal option. In the first quarter of fiscal 2020, the Company reassessed whether a sale would have occurred on the date of adoption of ASC 842, Leases, and, at which time, concluded that the buildings did not qualify for sale and lease back accounting in accordance with ASC 842. As a result, they were continuously accounted for as financing transactions.
 As of June 28, 2025, $ 0.2 million was included in Other current liabilities, and $ 15.5 million was included in Other non-current liabilities on the Consolidated Balance Sheets. As of June 29, 2024, $ 0.1 million was included in Other current liabilities, and $ 15.7 million was included in Other non-current liabilities on the Consolidated Balance Sheets.
 As of June 28, 2025, future minimum annual lease payments of Santa Rosa's non-cancelable leaseback agreements were as follows (in millions):

 Guarantees
 Authoritative guidance requires upon issuance of a guarantee the guarantor must recognize a liability for the fair value of the obligation that it assumes under the guarantee. In addition, disclosures about the guarantees that an entity has issued, including a tabular reconciliation of the changes of the entity's product warranty liabilities, are required.
 The Company from time to time enters into certain types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (i) divestiture agreements, under which the Company may provide customary indemnifications to purchasers of the Company's businesses or assets; (ii) certain real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company's use of the applicable premises; and (iii) certain agreements with the Company's officers, directors and employees, under which the Company may be required to indemnify such persons for liabilities arising out of their employment relationship.
 The terms of such obligations vary. Generally, a maximum obligation is not explicitly stated. Because the obligated amounts of these types of agreements often are not explicitly stated, the overall maximum amount of the obligations cannot be reasonably estimated. Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations on the Consolidated Balance Sheets as of June 28, 2025 and June 29, 2024.

 Outstanding Standby Letters of Credit and Performance Bonds
 As of June 28, 2025, the Company had standby letters of credit of $ 6.6 million, and other claims of $ 1.9 million collateralized by restricted cash.
 Product Warranties
 The Company provides reserves for the estimated costs of product warranties at the time revenue is recognized. Prior to January 1, 2023 the Company offered its customers warranties up to three years for most of its products. On January 1, 2023, the Company changed the standard warranty for most of its products to one year. The Company estimates the costs of its warranty obligations based on its historical experience of known product failure rates, use of materials to repair or replace defective products and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

 In July 2023, the Court of Appeals in the State of Kansas affirmed a lower court decision in a case filed by Aeroflex Wichita (Aeroflex), a VIAVI subsidiary, against Tel-Instrument Electronics Corp. (TIC) and two of its employees with total damages of $ 7.3 million owed to VIAVI. The lower court case, filed by Aeroflex prior to the acquisition by VIAVI and affirmed by the Kansas Court of Appeals, awarded damages caused by tortious interference and improper use and disclosure of Aeroflex's confidential and proprietary business information used by the defendants to win a competitive U.S. Army contract.
 TIC did not file a petition to appeal the decision and acknowledged its obligation to pay damages in full. VIAVI subsequently received total payments of $ 7.3 million from TIC and the two former employees and recorded a gain to Interest and other income, net in the Consolidated Statements of Operations for the year ended June 29, 2024.
 U.K. Pension Settlement
 In June 2016, the Company received a court decision regarding the validity of an amendment to a pension deed of trust related to one of its foreign subsidiaries which the Company contends contained an error requiring the Company to increase the pension plan's benefit. The Company had subsequently further amended the deed to rectify the error. The court ruled that the amendment increasing the pension plan benefit was valid until the subsequent amendment. The Company estimated the liability to range from 5.7 million to 8.4 million. The Company determined the likelihood of loss to be probable and accrued 5.7 million as of July 2, 2016 in accordance with authoritative guidance on contingencies.
 The Company pursued an appeal of the court decision. In March 2018, the appellate court affirmed the decision of the lower court. The Company pursued a motion for summary judgement on the deed of rectification claim. As of July 2, 2022, the related accrued pension liability of 5.4 million or $ 6.5 million was included in pension and post-employment benefits within Other non-current liabilities on the Consolidated Balance Sheets.

 In September 2022, the Company received a favorable court decision, which removed completely and definitively the obligation to fund the increased pension benefit with retrospective effect to 1999. As a result of the judgment, and in accordance with authoritative guidance on contingencies, the Company reversed the liability and recorded a gain (reduction to SG&A expense in the Consolidated Statements of Operations) of 5.7 million or $ 6.7 million during fiscal 2023.
 The Company is subject to a variety of claims and suits that arise from time to time in the ordinary course of its business. While management currently believes that resolving claims against the Company, individually or in aggregate, will not have a material adverse impact on its financial position, results of operations or statement of cash flows, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. Were an unfavorable final outcome to occur, there exists the possibility of a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the effect becomes reasonably estimable.

 Note 19. Operating Segments and Geographic Information
 The Company evaluates its operating segments in accordance with the authoritative guidance on segment reporting. The Company's Chief Executive Officer as the Company's CODM uses operating segment financial information to evaluate segment performance and to allocate resources.
 The Company's operating and reportable segments are:
 (i) Network and Service Enablement:
 NSE provides an integrated portfolio of testing, monitoring, assurance and security solutions to help build, maintain, and optimize telecom and datacom networks. Our solutions address lab and production environments, network management, service assurance and AIOps for any kind of network, including wireless, wireline, cloud, satellite, public safety, military and critical infrastructure. NSE also offers a range of product support and professional services such as repair, calibration, software support and technical assistance for its products.
 (ii) Optical Security and Performance Products:
 OSP leverages its core optical coating technologies and volume manufacturing capability to design, manufacture, and sell technologies for the anti-counterfeiting, 3D sensing, government and aerospace, automotive and industrial markets.
 Effective March 30, 2025, the Company realigned its segment reporting structure. As a result, the company's Network Enablement (NE) and Service Enablement (SE) business activities are now reported as a single operating and reportable segment, NSE. Recent acquisitions have reduced the SE segment revenue as a percentage of total VIAVI revenue. In addition, NE and SE are managed under common leadership, share many of the same customers and suppliers and operating expenses associated with the NSE business are not exclusively allocated to either NE or SE. The Company has applied this change retrospectively in the disclosures herein.
 Segment Reporting
 The CODM manages the Company in two broad business categories: NSE and OSP. The CODM evaluates segment performance of the NSE and OSP business based on segment operating margins. The CODM uses segment operating margin to make budgeting and forecasting decisions and to assess the performance of our segments, primarily by monitoring actual results versus the prior year, the annual budget and forecasted results. In addition, the CODM reviews inventory levels by segment. The Company allocates corporate-level operating expenses to its segment results, except for certain non-core operating and non-operating activities as discussed below.

 The Company does not allocate stock-based compensation, acquisition and integrated related charges, amortization of acquisition related intangibles, amortization of acquisition related inventory step-up, legal settlements, restructuring, changes in fair value of contingent consideration liabilities, non-operating income and expenses, or other charges unrelated to core operating performance to its segments because management does not include this information in its measurement of the performance of the operating segments. These items are presented as "Unallocated other expenses" in the table below. Additionally, the Company does not specifically identify and allocate all assets by operating segment.
 Information on the Company's reportable segments is as follows (in millions):

 Note 20. Government Assistance
 VALOR Grant
 In the third quarter of fiscal 2024, the U.S. National Telecommunications and Information Administration (NTIA) awarded VIAVI a grant from the Public Wireless Supply Chain Innovation Fund. The grant is expected to provide approximately $ 21.7 million in funding over a three-year performance period for the VIAVI Automated Lab-as-a-Service for Open RAN (VALOR). During the three-year performance period, VIAVI will be required to spend $ 5.8 million, consisting of $ 4.0 million for software license fees and $ 1.8 million for management/administrative fees to operate the lab.
 The Company recorded $ 7.1 million in the form of R&D credits in the Consolidated Statements of Operations during fiscal 2025 under the VALOR Grant. In addition, funding of $ 1.4 million offset the carrying value of lab equipment purchased during the fiscal year ended June 28, 2025. For the year ended June 28, 2025, we received cash reimbursement of $ 10.5 million and had pending receipts of $ 0.6 million included in Prepayments and other current assets on the Consolidated Balance Sheets.
 Other Government Assistance
 The Company recorded approximately $ 10.6 million for other government assistance, primarily R&D credits, in the Consolidated Statements of Operations during fiscal 2025. As of June 28, 2025, the Company had pending receipts of approximately $ 17.5 million related to other government assistance included in Prepayments and other current assets on the Consolidated Balance Sheets.

 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
 None.

 ITEM 9A. CONTROLS AND PROCEDURES
 (a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
 The SEC defines the term "disclosure controls and procedures" to mean a company's controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC's rules and forms. "Disclosure controls and procedures" include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act of 1934, as amended, is accumulated and communicated to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management. Our management (with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO)) has conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act). Based on such evaluation, our CEO and our CFO have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 28, 2025.

 (b) MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act). Our management, including our CEO and CFO, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its evaluation under the framework in the Internal Control-Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of June 28, 2025.
 In accordance with guidance issued by the Securities and Exchange Commission, companies are permitted to exclude acquisitions from their final assessment of internal control over financial reporting for the first fiscal year in which the acquisition occurred. Our management's evaluation of internal control over financial reporting excluded the internal control activities of Inertial Labs, Inc. (Inertial Labs), which we acquired on January 28, 2025, as discussed in "Note 5. Acquisitions" under Item 8 of this Annual Report on Form 10-K. We have included the financial results of Inertial Labs in the Consolidated Financial Statements from the date of acquisition. Total revenues of Inertial Labs subject to the Company's internal control over financial reporting represented approximately 2.3% of our consolidated revenue for the fiscal year ended June 28, 2025. Total assets of Inertial Labs subject to the Company's internal control over financial reporting represented approximately 2.1% of our consolidated total assets as of June 28, 2025. Inertial Lab's goodwill and intangible assets were subject to our management's evaluation of internal control over financial reporting.
 Our management has concluded that, as of June 28, 2025, our internal control over financial reporting was effective at the reasonable assurance level based on these criteria.
 The effectiveness of the Company's internal control over financial reporting as of June 28, 2025 has been audited by our independent registered public accounting firm PricewaterhouseCoopers LLP, as stated in their report which appears in this Annual Report on Form 10-K under Item 8 "Financial Statements and Supplementary Information."
 (c) CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
 There were no changes in our internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), during the quarter ended June 28, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
 (d) LIMITATIONS ON EFFECTIVENESS OF CONTROLS
 Our management, including our CEO and CFO, does not expect that our disclosure controls and procedures or our internal control will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. Accordingly, our disclosure controls and procedures and our internal control provide reasonable assurance of achieving their objectives.
