This Annual Report on Form 10-K (including certain information incorporated herein by reference) contains forward-looking statements made pursuant to Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 (the “PSLRA”). The statements in this Annual Report on Form 10-K that are not purely historical are forward-looking statements, including, without limitation, statements regarding our expectations, assumptions, beliefs, intentions or strategies regarding the future. In some cases, these forward-looking statements can be identified by terminology such as, “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “intends,” “estimates,” “predicts,” “projects,” “potential,” or “continue” or the negative of these terms or other comparable terminology. Forward-looking statements address, among other things, our assumptions, our expectations, our assessments of the size and growth rates of our markets, our growth strategies, our efforts to increase bookings, sales and revenues, projections of our future profitability, cash generation, success of our research, development and engineering investments, results of operations, capital expenditures, our financial condition, our ability to integrate acquired businesses or other “forward-looking” information and include statements about revenues, costs, investments, earnings, margins, or our projections, actions, plans or strategies.

The forward-looking statements in this Annual Report on Form 10-K involve risks and uncertainties, which could cause actual results, performance or trends to differ materially from those expressed in the forward-looking statements herein or in previous disclosures. We believe that all forward-looking statements made by us have a reasonable basis, but there can be no assurance that these expectations, beliefs or projections will actually occur or prove to be correct, at least on the timetable of our expectations. Actual results could differ materially. We claim the protection of the safe harbor for forward-looking statements contained in the PSLRA for our forward-looking statements.

The risk factors described in more detail herein under Item 1A. “Risk Factors” and summarized below under “Risk Factor Summary,” among others, in some cases have affected and in the future could affect our financial performance and actual results, and could cause actual results for fiscal 2026 and beyond to differ materially from those expressed or implied in any forward-looking statements included in this Annual Report on Form 10-K or otherwise made by our management.

All such factors, as well as factors described or referred to in other filings we make with the Securities and Exchange Commission (the “SEC”) from time to time, should be considered in evaluating our business and prospects. Many of these factors are beyond our reasonable control. In addition, we operate in a highly competitive and rapidly changing environment, and, therefore, new risk factors can arise and be present without market participants like us knowing until a substantial amount of time has passed. It is not possible for management to predict all such risk factors, assess the impact of all such risk factors on our business or estimate the extent to which any individual risk factor, or combination of risk factors, may impact our business. It is also not possible for management to mitigate all such risks, and therefore any such risk factor may cause results to differ materially from those contained in any forward-looking statement. The forward-looking statements included in this Annual Report on Form 10-K speak only as of the date of this Annual Report on Form 10-K. We do not assume any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or developments, or otherwise, except as may be required by the securities laws.

Manufacturing Processes

Our success in developing and manufacturing many of our products depends on our ability to tailor the optical and physical properties of technically challenging materials, components, and photonics-based solutions across our target markets. The ability to produce these complex materials, and to control their quality and in-process yields, is an expertise of the Company that is critical to our customers. In the markets we serve, there is a limited number of high-quality suppliers of many of the components we manufacture. Aside from datacenter transceivers, there are very few industry-standard products. Our lasers are displacing conventional technologies because they can do the job faster, yield higher quality, provide overall economic benefits, and enable next-generation applications. Overall, our key differentiators are our deep technology expertise combined with our ability to deliver volume solutions at scale.

We continue to increase our use of renewable energy to power our operations and lower our greenhouse gas footprint. We have on-site solar systems at several facilities that further contribute to our renewable energy efforts. Our team also works to minimize energy usage, water usage, other raw materials usage, and waste generation. Coherent has set as a top priority to reduce its carbon footprint across its global operations. Additional information on the Company’s sustainability performance can be found on the ESG section of our website at www.coherent.com. The website address is intended to be an inactive textual reference only. None of the information on, or accessible through, our website is part of this Annual Report on Form 10-K, nor is it incorporated herein by reference.

Sources of Supply

In our production processes, we use numerous optical, electrical, and mechanical parts that are sourced from third-party suppliers. These include ICs, DSPs, mechanical housings, and optical components, and we commonly refer to them as raw materials. Raw materials or subcomponents required in the manufacturing process are generally available from several sources. However, in the Lasers segment, we currently purchase several key components and materials used in the manufacture of our products, including exotic materials, crystals, and optics, from sole-source or limited-source suppliers. We also purchase assemblies and turnkey solutions from contract manufacturers, based on our proprietary designs. We rely on our own production and design capability to manufacture and specify certain strategic components, crystals, fibers, semiconductor lasers, and laser-based systems. We use rare-earth materials in some of our production processes. Like with other materials, we are constantly working to strengthen and diversify our supply chain for resilience. These strategies include maintaining additional buffer stocks and securing multiple sources to ensure resilience.

The continued high quality of and access to these raw materials are critical to the stability and predictability of our manufacturing yields. We specify and test these raw materials at the onset of and throughout the production process. Additional research and capital investment are sometimes needed to better define future raw materials specifications. We continue to develop strategic second sources as part of our overall business continuity planning, and occasionally experience problems associated with raw materials not meeting contract specifications for quality or purity. Risks associated with reliance on third parties for the timely and reliable delivery of raw materials are discussed in greater detail in Item 1A. Risk Factors of this Annual Report on Form 10-K.

Item 1A.     RISK FACTORS

The following are certain risk factors that could affect our business, results of operations, financial condition or cash flows. These risk factors should be considered along with any forward-looking statements contained in this Annual Report on Form 10-K, because these factors could cause our actual results or financial condition to differ materially from those projected in forward-looking statements. The following discussion is not an all-inclusive listing of risks, although we believe these are the material risks that we face. If any of the following occur, our business, results of operations, financial position, or cash flows could be adversely affected. You should carefully consider these factors, as well as the other information contained in this Annual Report on Form 10-K, when evaluating an investment in our securities.

Risks Related to Our Business, Operations and Industry

Our competitive position depends on our ability to develop new products and processes and may require significant investment.

To meet our strategic objectives, we must develop, manufacture, and market new products and continue to update our existing products and processes to keep pace with sudden increases and decreases in market demand and other market developments and to address increasingly sophisticated customer requirements in rapidly evolving technologies. Our success in developing and selling new and enhanced products and processes depends upon a variety of factors, including strategic product selection, efficient completion of product design and development, timely implementation of manufacturing and assembly processes, effective sales and marketing, and high-quality and successful product performance in the market.

The introduction by our competitors of products or processes using new developments that are better or lower cost than ours could render our products or processes obsolete or unmarketable. We intend to continue to make significant investments in research, development, and engineering to achieve our goals. There can be no assurance that we will be able to develop and introduce new products or enhancements to our existing products and processes in a manner which satisfies customer needs or achieves market acceptance. The failure to do so could have a material adverse effect on our ability to grow our business and maintain our competitive position and on our results of operations and/or financial condition.

We continuously monitor the marketplace for strategic opportunities, and our business strategy includes expanding our product lines and markets through both internal product development and acquisitions. Consequently, we expect to continue to consider strategic acquisitions of businesses, products, or technologies complementary to our business. This may require significant investments of management time and financial resources. If market demand is outside our organic capabilities, if a strategic acquisition is required and we cannot identify one or execute on it, and/or if financial investments that we undertake distract management, do not result in the expected return on investment, expose us to unforeseen liabilities, or jeopardize our ability to comply with our credit facility covenants due to any inability to integrate the business, adjust to operating a larger and more complex organization, adapt to additional political and other requirements associated with the acquired business, retain staff, or work with customers, we could suffer a material adverse effect on our business, results of operations, or financial condition.

We continue to make investments in programs with the goal of gaining a greater share of end markets, including the key components for fast growth markets. We cannot guarantee that our investments in capital and capabilities will be sufficient. The potential end markets, as well as our ability to gain market share in such markets, may not materialize on the timeline anticipated or at all. We cannot be sure of the end market price, specification, or yield for products incorporating our technologies. Our technologies could fail to fulfill, partially or completely, our target customers’ specifications. We cannot guarantee the end market customers’ acceptance of our technologies. Further, we may be unable to fulfill the terms of our contracts with our target customers, which could result in penalties of a material nature, including damages, loss of market share, and loss of reputation.

A significant portion of our business is subject to cyclical market factors and we may fail to accurately estimate the size and growth rate of our markets and our customers’ demands.

Our business is dependent on the demand for products produced by end-users of communications, industrial, instrumentation and electronics markets. Many of these end-users are in industries that have historically experienced a highly cyclical demand for their products. We make significant decisions based on our estimates of customer requirements. We use our estimates to determine the levels of business we seek and accept, production schedules, personnel needs, and other resource requirements.

Our markets are characterized by extensive research and development, rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. The nature of these markets require significant research and development expenses to participate, with substantial resources invested in advance of material sales of our products to our customers. To compete effectively, we must continually address the challenges of dynamic and accelerating market trends and competitive developments. Otherwise, our product offerings may become less competitive given the frequent introduction of alternative or more cost-effective technologies. Because this industry is subject to rapid change, it is difficult to predict its potential size or future growth rate. We cannot ensure that our expenditures for research and development will result in the launch of new products or, if such products are introduced, that those products will achieve sufficient market acceptance

16

or generate sales to offset the costs of development. Our failure to address rapid technological changes in our markets, or the failure of either our customers’ or our products to gain market acceptance, or the failure of the markets in which we participate to grow could adversely affect our business and results of operations.

In addition, customers may require rapid increases in production on short notice. We may not be able to purchase sufficient supplies or allocate sufficient manufacturing capacity to meet such increases in demand. Rapid customer ramp-up and significant increases in demand may strain our resources or negatively affect our margins. Inability to satisfy customer demand in a timely manner may harm our reputation, reduce our other opportunities, damage our relationships with customers, reduce revenue growth, and/or cause us to incur contractual penalties.

Alternatively, downturns in the industries in which we compete, or changes in technology, may cause our customers to significantly and abruptly reduce their demand, or even cancel orders. For example, the artificial intelligence industry is rapidly evolving, with continuous improvements in algorithms, software efficiencies and hardware capabilities. Emerging AI technologies, such as those demonstrated by DeepSeek, may allow for complex AI operations to be executed with significantly less computing power than is currently required. This reduction in computational intensity could decrease the demand for services provided by AI datacenters that are our customers. Shifts like these could have an adverse effect on our business, results of operations and financial condition, as we base many of our operating decisions including, but not limited to, those regarding manufacturing capacity and staffing, and enter into purchase commitments, on the basis of anticipated revenue trends. With respect to orders we initiate with our suppliers to address anticipated demand from our customers, certain suppliers may have required noncancellable purchase commitments or advance payments from us, and those obligations and commitments could reduce our ability to adjust our inventory or expense levels to reflect declining market demands. Should revenues in future periods fall substantially below our expectations, or should we fail to accurately forecast changes in demand mix, we could be required to record substantial charges for obsolete or excess inventories or noncancellable purchase commitments. Because certain of our sales, research and development, and internal manufacturing overhead expenses are relatively fixed, a reduction in customer demand likely would decrease our gross margins and operating income.

We contract with a number of large end-user service providers and product companies that have considerable bargaining power, which may require us to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues. Any loss, cancellation, reduction, or delay in purchases by these large customers could harm the longevity of our business.

A small number of customers have consistently accounted for a significant portion of our revenues, with two customers each contributing more than 10% of total revenues in fiscal 2025. Our success will depend on our continued ability to develop and manage relationships with our large customers and their continued need for our products. Although we are attempting to expand our customer base, we expect that significant customer concentration will continue for the foreseeable future. We may not be able to offset any decline in revenues from our existing large customers with revenues from new customers, and our quarterly results may be volatile because we are dependent on large orders from these customers that may be reduced, delayed, or cancelled. The markets in which we have historically sold our optical subsystems and components products are dominated by a relatively small number of systems manufacturers, thereby limiting the number of our potential customers.

Our dependence on large orders from a relatively small number of large customers makes our relationship with each large customer critically important to our business. We cannot ensure that we will be able to retain our large customers, attract additional large customers, or that our large customers will be successful in selling their products that incorporate our products. In addition, governmental trade action or economic sanctions may limit or preclude our ability to do business with certain large customers. We have in the past experienced delays and reductions in orders from some of our large customers. In addition, our large customers have in the past sought price concessions from us, and we expect that they will continue to do so in the future. Cost and expense reduction measures that we have implemented over the past several years, and additional action we are taking to reduce costs, may adversely affect our ability to introduce new and improved products, which may, in turn, adversely affect our relationships with some of our large customers. Further, some of our large customers may in the future shift their purchases of products from us to our competitors or to joint ventures between these customers and our competitors, or may in certain circumstances produce competitive products themselves. The loss of one or more of our large customers, any reduction or delay in sales to these customers, our inability to successfully develop relationships with additional customers, or future price concessions that we may make could significantly harm our business.

Large end-user service providers and product companies comprise a significant portion of our customer base. These large customers generally have greater purchasing power than smaller customers and, accordingly, often negotiate more favorable terms from suppliers, including us. As we seek to expand our sales to existing and new large customers, we may be required to agree to terms and conditions that are more favorable to these customers and that may affect the timing of our ability to recognize revenue, increase our costs, and have an adverse effect on our business, results of operations and financial condition. Furthermore, large customers have increased buying power and ability to negotiate onerous terms into our contracts with them, including pricing, warranties, indemnification and production capability terms. If we are unable to satisfy the terms of these contracts, it could result in liabilities of a material nature, including litigation, damages, additional costs, loss of market share,

17

and loss of reputation. Additionally, the terms these large customers require, such as most-favored customer or exclusivity provisions, may impact our ability to do business with other customers and generate revenues from such customers.

Products that fail to meet specifications, are defective, or are otherwise incompatible with end uses could impose significant costs on us.

Products that do not meet specifications or that contain, or are perceived by our customers to contain, defects or that are otherwise incompatible with end uses could impose significant costs on us or otherwise materially adversely affect our business, results of operations, or financial condition. From time to time, we experience problems with nonconforming, defective, or incompatible products after we have shipped such products. In recent periods, we have further diversified and expanded our product offerings, which could potentially increase the chance that one or more of our products could fail to meet specifications in a particular application. Our products and solutions may be deemed fully or partially responsible for functionality in our customers’ products and may result in sharing or shifting of product or financial liability from our customers to us for costs incurred by the end user as a result of our customers’ products failing to perform as specified. In addition, if our products and solutions perform critical functions in our customers’ products our potential liability may increase. We could be adversely affected in several ways, including the following:

•we may be required or agree to compensate customers for costs incurred or damages caused by defective or incompatible products and to replace products;

•we could incur a decrease in revenue or adjustment to pricing commensurate with the reimbursement of such costs or alleged damages; and

•we may encounter adverse publicity, which could cause a decrease in sales of our products or harm our reputation or relationships with existing or potential customers.

Any of the foregoing items could have a material adverse effect on our business, results of operations, or financial condition.

We may encounter increased competition, and we may fail to accurately estimate our competitors’ or our customers’ willingness and capability to backward integrate into our competencies and thereby displace us.

We may encounter substantial competition from other companies in the same market, including established companies with significant resources. Some of our competitors may have financial, technical, marketing, or other capabilities that are more extensive than ours. They may be able to respond more quickly than we can to new or emerging technologies and other competitive pressures. We may not be able to compete successfully against our present or future competitors. Our failure to compete effectively could have a material adverse effect on our business, results of operations, or financial condition.

Global economic downturns may adversely affect our business, results of operations, and financial condition.

Downturns in regional or worldwide economies, due to inflation, geopolitics, major central bank policy actions including interest rate increases, public health crises, or other factors, have harmed our business in the past and current and future downturns could also adversely affect our business. Adverse economic conditions affect demand for our products and devices that incorporate our products, Reduced demand for these or other products could result in significant decreases in our product sales. In addition, to the extent our customers have elevated inventory levels or are impacted by deterioration in credit markets, we may experience a decrease in short-term and/or long-term demand resulting in industry oversupply and declines in pricing for our products.

A deterioration of conditions in regional or worldwide credit markets could limit our ability to obtain external financing to fund our operations and capital expenditures. Difficult economic conditions may also result in a higher rate of losses on our accounts receivable due to credit defaults. Additionally, our current or future customers may experience cash flow problems and as a result may modify, delay, or cancel plans to purchase our products. Any inability of our current or future customers to pay us for our products may adversely affect our earnings and cash flow. As a result, downturns in regional or worldwide economies could have a material adverse effect on our business, results of operations, or financial condition.

We depend on highly complex manufacturing processes that require strategic materials, components, and products from limited sources of supply.

Our operations are dependent upon a supply chain of difficult-to-make or difficult-to-refine products and materials, including integrated circuits, mechanical housings and optical components, and some of our product inflow is subject to yield reductions from growth or fabrication losses, and thus the quantities we may receive are not consistently predictable. Customers may also change a specification for a product that our suppliers cannot meet which may limit and/or otherwise impact our ability to supply such customers.

Some of our products require designs and specifications that are at the cutting-edge of available technologies and change frequently to meet rapidly evolving market demands. By their very nature, the types of components used in such products can be difficult and unpredictable to manufacture and may only be available from a single supplier, which increases the risk that we may not obtain such components in a timely manner. Identifying alternative sources of supply for certain components could be

18

difficult and costly, result in management distraction in assisting our current and future suppliers to meet our and our customers’ technical requirements, and cause delays in shipments of our products while we identify, evaluate and test the products of alternative suppliers. Any such delay in shipment would result in a delay or cancellation of our ability to convert such orders into revenues. Furthermore, financial or other difficulties faced by these suppliers or significant changes in demand for these components or materials could limit their availability. We continue to consolidate our supply base and move supplier locations. When we transition locations, we may increase our inventory of such products as a “safety stock” during the transition, which may cause the amount of inventory reflected on our balance sheet to increase. Additionally, many of our customers rely on sole source suppliers. In the event of a disruption of our customers’ supply chain, orders from our customers could decrease or be delayed.

We also make products of which we are one of the world’s largest suppliers. We use high-quality, optical-grade ZnSe in the production of many of our IR optical products. We are a leading producer of ZnSe for our internal use and for external sale. The production of ZnSe is a complex process requiring a highly controlled environment. A number of factors, including defective or contaminated materials, could adversely affect our ability to achieve acceptable manufacturing yields of high-quality ZnSe. Lack of adequate availability of high-quality ZnSe could have a material adverse effect upon our business. There can be no assurance that we will not experience manufacturing yield inefficiencies that could have a material adverse effect on our business, results of operations, or financial condition.

In addition, we use rare earth minerals and produce and use high-purity and relatively uncommon materials and compounds to manufacture our products, including, but not limited to, ZnS, GaAs, yttrium aluminum garnet, yttrium lithium fluoride, calcium fluoride, germanium, selenium, telluride, Bi2Te3, and SiC. A significant failure of our internal production processes or our suppliers to deliver sufficient quantities of these necessary materials (including, in the case of rare earth minerals, as a consequence of their limited diminished availability or as a result of export controls on such materials) on a timely basis could have a material adverse effect on our business, results of operations, or financial condition.

We manufacture some of the components that we incorporate into our subsystem products; in other cases, we provide components to contract manufacturers to produce finished or intermediary goods. For some of the components and finished or intermediary goods, we are the sole qualified manufacturer. Our manufacturing processes are highly complex, and quality issues are often difficult to forecast, detect, and correct. From time to time we have experienced problems achieving acceptable yields in our manufacturing facilities, resulting in delays in the availability of our products. In addition, if we experience problems with our manufacturing facilities, it would be costly and require a long period of time to move the manufacture of these components and finished good products to a different facility or contract manufacturer, which could result in interruptions in supply and would likely materially impact our results of operations and financial condition. In addition, for a variety of reasons, including changes in circumstances at our contract manufacturers or our own business strategies, we may voluntarily, or be required to, transfer the manufacturing of certain products to other manufacturing sites.

Changes in manufacturing processes are often required due to changes in product specifications, yield improvements, changing customer needs, and the introduction of new products. These changes may reduce manufacturing yields at our contract manufacturers and at our own manufacturing facilities, resulting in reduced margins on and/or reduced availability of those products. Also, our ability to control the quality of products produced by contract manufacturers may be limited and quality issues may not be resolved in a timely manner, which could adversely impact our financial condition or results of operations. In addition, many of our products are sourced from suppliers based outside of the United States, primarily in Asia. Uncertainty with respect to tax and trade policies, tariffs, and government regulations affecting trade between the United States and other countries has recently increased. Major developments in tax policy or trade relations, such as the imposition of tariffs on imported products, could increase our product and product-related costs or require us to seek alternative suppliers, either of which could result in decreased sales or increased product and product-related costs.

Significant political, trade, regulatory developments, and other circumstances beyond our control, including as a result of recently announced tariffs, could have a material adverse effect on our financial condition or results of operations.

We operate globally and sell or plan to sell our products in countries throughout the world. Significant political, trade, or regulatory developments in the jurisdictions in which we sell our products, such as those stemming from the change in the U.S. federal administration, are difficult to predict and may have a material adverse effect on us. Similarly, changes in U.S. federal policy that affect the geopolitical landscape could give rise to circumstances outside our control that could have negative impacts on our business operations. For example, in early 2025, the United States implemented significant new tariffs on foreign imports impacting multiple countries, commodities and industries, and these new tariffs and export restrictions also prompted retaliatory tariffs and export restrictions from certain countries. As of June 2025, certain tariffs and retaliatory tariffs have been delayed, but a number of the new tariffs remain in effect, including significant tariffs and trade sanctions between the United States and China. Historically, tariffs have led to increased trade and political tensions and, to date, the outcome of the negotiations between the United States and the various countries is not yet clear. Political tensions as a result of trade policies could reduce trade volume, investment, technological exchange and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets.

19

Any changes in political, trade, regulatory, and economic conditions, including U.S. trade policies, could have a material adverse effect on our financial condition or results of operations.

Our business is subject to various governmental regulations. Compliance with these regulations may cause us to incur significant expense and failure to maintain compliance with applicable regulations could adversely affect our business.

Our business is subject to various domestic and international laws and other legal requirements, including ant-competition and import/export regulations, such as the U.S. Export Administration Regulations (“EAR”), and applicable executive orders. These laws, regulations and orders are complex, may change frequently and with limited notice, and generally become more stringent over time. The Bureau of Industry and Security of the U.S. Department of Commerce (“BIS”) has issued final rules under the EAR that restrict access by Huawei Technologies Co. Ltd. and certain of its affiliates (collectively, “Huawei”) to items produced domestically and abroad from certain U.S. technology, software, and equipment. These rules prevent us from selling certain products subject to the EAR to identified Huawei entities without a license issued by BIS. In January 2025, we received an inquiry from BIS concerning past product sales to Huawei; we are cooperating with BIS’s inquiry and conducting an internal review of those sales to determine what products are subject to the EAR and consequently restricted for export, reexport, and transfer when Huawei is a party to the transaction. We have stopped shipping products to Huawei, and we are in discussions with BIS regarding past product sales. At this time, we cannot predict the outcome of these discussions; cannot determine an estimate or range of loss; and we may be required to incur significant penalties and/or costs or expense to comply with, or to remedy any violations of, these regulations. The U.S. government may continue to add companies to its restricted entity list and/or technologies to its list of prohibited exports to specific countries, which have had and may in the future have an adverse effect on our revenue and our ability to sell our products. These restrictive governmental actions and any similar measures that may be imposed on U.S. companies by other governments, especially in light of ongoing trade tensions with China, will likely limit or prevent us from doing business with certain of our customers or suppliers and harm our ability to compete effectively or otherwise negatively affect our ability to sell our products. Furthermore, government authorities may take retaliatory actions, impose conditions for the supply of products or require the license or other transfer of IP, which could have a material adverse effect on our business.

Increases in commodity prices and diminished availability of rare earth minerals and noble gases may adversely affect our results of operations and financial condition.

We are exposed to a variety of market risks, including the effects of increases in commodity prices and diminished availability of rare earth minerals and noble gases. Our businesses purchase, produce, and sell raw materials based upon quoted market prices from minor metal exchanges. Trade disputes, geopolitical tensions, economic circumstances, or political conditions may limit our ability to obtain certain materials. Although rare earth and other materials are generally available from multiple suppliers, China is the predominant producer of certain of these materials. In 2024, China imposed export restrictions on certain rare earth minerals such as yttrium and germanium, which disrupted and may continue to disrupt global supply chains, driving up costs. The negative impact from increases in commodity prices and diminished availability of rare earth minerals and noble gases might not be recovered through our product sales, which could have a material adverse effect on our results of operations and financial condition.

Cybersecurity attacks and incidents and other vulnerabilities could subject us to costly damages, claims and expenses, harm to our reputation or competitive position, or disrupt our operations and business.

We depend on secure information technology for our business and are exposed to risks related to cybersecurity threats and other cyber incidents affecting our operations, facilities, systems and networks, and those of our customers, suppliers and service providers, and other third parties.

We have experienced cybersecurity incidents and some of these have resulted in data breaches. Thus far, none of these incidents or breaches have materially affected our ability to conduct our business, our results of operations, or our financial condition. However, we continue to face cyber and other security threats. Particularly in light of the nature of our industry, size of our company and workforce, reliance on third party suppliers and information technology and the global scope of our operations, we expect we will be subject to additional cyber-attacks and other security incidents in the future, including from nation states and non-state actors. While we continue to invest in the cybersecurity and resiliency of our networks and to enhance our internal controls and processes designed to help protect our systems and infrastructure, and the information they contain, given the complex, ongoing, and evolving nature of cyber and other security threats, these efforts may not be fully effective, particularly against previously unknown vulnerabilities and third party risks that go undetected for an extended period of time.

Our information technology and cybersecurity program also incorporate and rely on technology, products and services that are provided by service providers and other third parties (“third parties”), which means that Company is susceptible to certain vulnerabilities, outages and other incidents impacting these third parties and the technology, products and services they provide (“third party technology”). Further, our customers, vendors and other service providers also rely on third-party technology, which means that we may also be impacted by incidents affecting the third-party technology that our customers, vendors and service providers use and rely on. In some cases, our customers, vendors and other service providers may rely on the same

20

third-party technology as we do, which means that outages, errors and other incidents impacting third parties and third party technology can impact both us, as well as our customers, vendors and service providers, which can have a compounding effect.

Cyber events (including cybersecurity incidents, breaches, outages and other incidents), if not prevented or effectively mitigated, have caused and could cause harm and require remedial actions. They could also damage our reputation, disrupt performance, impact our ability to obtain future insurance coverage, and lead to loss of business, regulatory actions, liabilities or other financial losses, for which we do not have adequate sources of recovery. The occurrence and impact of these various risks are difficult to predict, but one or more of them could have a material adverse effect on our business, results of operations, or financial condition.

We may be adversely impacted by any of the multiple uncertainties and outcomes associated with the use and evolution of Artificial Intelligence (“AI”).

We are increasingly incorporating AI capabilities into the development of technologies and our business operations, and into our products and services. AI technology is complex and rapidly evolving, and may expose us to significant competitive, legal, regulatory, and other risks. The implementation of AI can be costly and there is no guarantee that our use of AI will enhance our technologies, benefit our business operations, or produce products and services that are preferred by our customers. AI will likely increase or change the competitive environment in our markets. Our competitors may be more successful in their AI strategy or they may have access to greater AI resources or technology and develop superior products and services.

Additionally, AI algorithms or training methodologies may be flawed, and datasets may contain irrelevant, insufficient or biased information, which can cause errors in outputs. AI is also the subject of an evolving set of legal requirements and regulations in various jurisdictions around the world in which we operate, and we may be subject to new and conflicting laws and regulations relating to AI. Any of these matters may create compliance risks, give rise to legal liability, damage our reputation, and materially harm our business.

Natural disasters or other global or regional catastrophic events could disrupt our operations, give rise to substantial environmental hazards, and adversely affect our results.

We and our subcontractors manufacture products using highly complex processes that require technologically advanced equipment and continuous modification to improve yields and performance. Difficulties in the manufacturing process or the effects from a shift in product mix can reduce yields or disrupt production and may increase our manufacturing costs. We and our subcontractors maintain operations and continuously implement new product and process technologies at manufacturing facilities, which are widely dispersed in multiple locations in several countries including the United States, Germany, Malaysia, and China. As a result of the interdependence within our network of manufacturing facilities, an operational disruption at one of our or a subcontractor’s facilities may have a disproportionate impact on our ability to produce many of our products.

From time to time, there have been disruptions in our manufacturing operations as a result of power outages, improperly functioning equipment, disruptions in supply of raw materials or components, or equipment failures. We have manufacturing and other operations in locations subject to natural occurrences and possible climate changes, such as severe and variable weather and geological events resulting in increased costs, or disruptions to our manufacturing operations or those of our suppliers or customers. In addition, climate change may pose physical risks to our manufacturing facilities or our suppliers’ facilities, including increased extreme weather events that could result in supply delays or disruptions. Other events, including political or public health crises, such as an outbreak of contagious diseases, may also affect our production capabilities or that of our suppliers, including as a result of quarantines, closures of production facilities, lack of supplies, or delays caused by restrictions on travel or shipping. Events of the types noted above have occurred from time to time and, because these risks are a characteristic of our business, they may occur in the future. As a result, in addition to disruptions to operations, our insurance premiums may increase or we may not be able to fully recover any sustained losses through insurance.

We may be unable to successfully implement our acquisitions strategy, integrate acquired companies and personnel with existing operations, or capitalize on any decision to strategically divest one or more current businesses.

We have completed acquisitions and divestitures in the past, including most recently the acquisition of Coherent, Inc. in July 2022. We expect to expand and diversify our operations with additional acquisitions, but we may be unable to identify or complete prospective acquisitions for many reasons, including increasing competition from other potential acquirers, the effects of consolidation in our industries, and potentially high valuations of acquisition candidates. In addition, applicable competition laws and other regulations may limit our ability to acquire targets, integrate businesses, or force us to divest an acquired business line. If we are unable to identify suitable targets or complete acquisitions, our growth prospects may suffer, and we may not be able to realize sufficient scale and technological advantages to compete effectively in all markets.

To the extent that we complete acquisitions, the success of our acquisitions will depend in large part on our success in integrating the acquired operations, strategies, technologies, and personnel. We may be unsuccessful in integrating acquired companies or product lines with existing operations, or may fail to realize some or all of the anticipated benefits of an acquisition if the integration process is more difficult or more costly than anticipated. If we fail to meet the challenges involved

21

in successfully integrating any acquired operations or to otherwise realize any of the anticipated benefits of an acquisition, including any expected cost savings and synergies, our operations could be impaired. In addition, the overall integration of an acquired business can be a time-consuming and expensive process that, without proper planning and effective and timely implementation, could significantly disrupt our business.

Some of the risks that may affect our ability to integrate or realize anticipated benefits from acquired companies, businesses, or assets include those associated with:

•a significant negative financial result from the acquired company relative to our pre-acquisition expectations, including potential unknown liabilities associated with the acquired company;

•retaining key employees and existing customers of the acquired company;

•standardizing the combined company’s standards, processes, procedures, and controls, including integrating enterprise resource planning systems and other key business applications;

•coordinating new product and process development;

•integrating management teams, strategies, technologies and operations, products, services, and corporate cultures;

•increasing complexity from combining operations;

•increasing the scope, geographic diversity, and complexity of our operations;

•difficulties in consolidating facilities and transferring processes and know-how;

•diversion of management’s attention from other business concerns; and

•actions we may take in connection with acquisitions, such as:

•using a significant portion of our available cash;

•issuing equity securities, which would dilute current shareholders’ percentage ownership;

•incurring significant debt;

•incurring or assume contingent liabilities, known or unknown, including potential lawsuits, infringement actions, or similar liabilities;

•incurring impairment charges related to goodwill or other intangibles; and

•facing antitrust or other regulatory inquiries or actions.

Our success requires us to attract, retain, and develop key personnel and maintain good relations with our employees.

We are highly dependent upon the experience and continuing services of certain scientists, engineers, production, sales, and management personnel. Competition for the services of these personnel is intense. There can be no assurance that we will be able to retain or attract the personnel necessary for our success. The loss of the services of our key personnel could have a material adverse effect on our business, results of operations, or financial condition. Our failure to execute on our succession planning may affect our ability to maintain our differentiated knowledge base.

Actions that we are taking to restructure our business in alignment with our strategic priorities may not be as effective as anticipated.

In May 2023, we announced that our Board of Directors approved a restructuring plan (the “2023 Plan”) which includes site consolidations, facilities movements and closures, and the relocation and requalification of certain manufacturing facilities. Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of our business discussed during our earnings call for the first quarter of fiscal 2025, our management approved a plan to take a number of restructuring actions, including site consolidations, facilities moves and closures, workforce reductions, contract terminations and certain other associated cost reductions (the “2025 Plan,” and together with the 2023 Plan, the “Restructuring Plans”). While the Restructuring Plans and other proactive cost reduction measures that we plan to take are intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model, we may encounter challenges in the execution of these efforts that could prevent us from recognizing the intended benefits of such efforts.

As a result of the 2023 Plan, we have incurred approximately $200 million of pre-tax charges in fiscal years 2023 to 2025 primarily as a result of the reduction in force and facility consolidations related to the closure and relocation of sites. We also have incurred, and may continue to incur, additional costs in the near term, including cash payments related to severance, employee benefits and employee transition costs, as well as non-cash charges for share-based compensation expense.

The Restructuring Plans may result in other unintended consequences, including higher than anticipated costs in implementing planned workforce reductions, particularly in highly regulated locations outside the United States; higher than anticipated lease termination and facility closure costs; employee attrition beyond our intended reduction in force; and decreased employee morale among our remaining employees; diversion of management attention; adverse effects to our reputation as an employer which could make it more difficult for us to hire new employees in the future; loss of the institutional knowledge and expertise of departing employees; failure to maintain adequate controls and procedures while executing, and subsequent to completing, the Restructuring Plans; and potential failure or delays to meet operational and growth targets due to the loss of qualified employees.

22

If we experience any of these adverse consequences, the Restructuring Plans and other cost reduction initiatives that we may undertake may not achieve or sustain the intended benefits. Our failure to achieve the expected results from the Restructuring Plans and other cost reduction initiatives for any reason also could lead to the implementation of additional restructuring-related activities in the future, which may exacerbate these risks or introduce new risks which could adversely affect our business, results of operations and financial condition.

If our goodwill or intangible assets become impaired, we may be required to record a significant charge to earnings.

Under accounting principles generally accepted in the United States, we review our intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill and indefinite life intangible assets are required to be tested for impairment at least annually. Factors that may be considered in determining whether a change in circumstances indicating that the carrying value of our goodwill or other intangible assets may not be recoverable include declines in our stock price and market capitalization or future cash flows projections. A decline in our stock price, or any other adverse change in market conditions, particularly if such change has the effect of changing one of the critical assumptions or estimates we used to calculate the estimated fair value of our reporting units, could result in a change to the estimation of fair value that could result in an impairment charge. Any such material charges, whether related to goodwill or purchased intangible assets, may have a material negative impact on our financial and operating results.

Risks Related to Intellectual Property and Litigation

There are limitations on the protection of our intellectual property, and we may from time to time be involved in costly intellectual property litigation or indemnification.

We rely on a combination of trade secret, patent, copyright, and trademark laws, combined with employee confidentiality, noncompetition, and nondisclosure agreements to protect our intellectual property rights. We cannot ensure that our employees with key knowledge will not be employed by our competitors. There can be no assurance that the steps we take will be adequate to prevent misappropriation of our technology or intellectual property. Furthermore, there can be no assurance that third parties will not assert infringement claims against us in the future.

Asserting our intellectual property rights or defending against third-party claims could involve substantial expense. In the event that a third party were successful in a claim that one of our products or processes infringed its proprietary rights, we could be required to pay substantial damages or royalties, or spend substantial amounts in order to obtain a license or modify our products or processes so that they no longer infringe such proprietary rights. Any such event could have a material adverse effect on our business, results of operations, or financial condition.

The design, processes, and specialized equipment utilized in our engineered materials, advanced components, and subsystems are innovative, complex, and difficult to duplicate. However, there can be no assurance that others will not develop or patent similar technology, or that all aspects of our proprietary technology will be protected. Others have obtained patents covering a variety of materials, devices, equipment, configurations, products, and processes, and others could obtain patents covering technology similar to ours. We may be required to obtain licenses under such patents, and there can be no assurance that we would be able to obtain such licenses, if required, on commercially reasonable terms, or that claims regarding rights to technology will not be asserted that may adversely affect our results of operations. In addition, our research and development contracts with agencies of the U.S. government present a risk that project-specific technology could be disclosed to competitors as contract reporting requirements are fulfilled. We also enter development projects from time to time that might result in intellectual property developed during a project that is assigned to the other party without us retaining rights to that intellectual property or is jointly owned with the other party.

Legal, regulatory and administrative investigations, inquiries, proceedings, and claims could have a material adverse effect on our business, results of operations, or financial condition.

From time to time, we are subject to various legal, regulatory and administrative investigations, inquiries, proceedings, and claims that arise out of the ordinary conduct of our business or otherwise, both domestically and internationally. We may be associated with and subject to litigation, claims, inquiries, investigations or disputes arising from, or as a result of:

•our relationships with vendors or customers, supply agreements, or contractual obligations with our subcontractors or other business partners;

•the actions of our vendors, subcontractors, or business partners;

•our indemnification obligations, including obligations to defend our customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, trademarks, copyrights, or trade secrets; and

•the terms of our product warranties or from product liability claims.

Risks Related to Laws and Regulations

23

Government actions and regulations, such as export restrictions, tariffs, and trade protection measures, may limit our ability to sell our products to certain customers or markets, or could otherwise restrict our ability to conduct operations.

International trade disputes, geopolitical tensions, and military conflicts have led, and continue to lead, to new and increasing export restrictions, trade barriers, tariffs, and other trade measures that can increase our manufacturing costs, make our products less competitive, reduce demand for our products, limit our ability to sell to certain customers or markets, limit our ability to procure, or increase our costs for, components or raw materials, impede or slow the movement of our goods across borders, impede our ability to perform R&D activities, or otherwise restrict our ability to conduct operations. Increasing protectionism, economic nationalism, and national security concerns may lead to further changes in trade policy, domestic sourcing initiatives, or other formal and informal measures that could make it more difficult to sell our products in, or restrict our access to, some markets and/or customers.

We cannot predict what actions may be taken with respect to export regulations, tariffs, or other trade regulations between the United States and other countries, what products or companies may be subject to such actions, or what actions may be taken by other countries in retaliation. Further changes in trade policy, tariffs, restrictions on exports or other trade barriers, or restrictions on supplies, equipment, and raw materials including rare earth minerals, may limit our ability to produce products, increase our selling and/or manufacturing costs, decrease margins, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies. For example, increasing geopolitical tensions could result in new export controls associated with products that support or enable AI Applications which could, in turn, restrict future sales of certain products to China or other markets. Such changes may also result in reputational harm to us, the development or adoption of technologies that compete with our products, long-term changes in global trade and technology supply chains, or negative impacts on our customers’ products which incorporate our solutions. Any of the effects described in this risk factor could have a material adverse effect on our business, results of operations, or financial condition.

The technology industry is subject to intense media, political, and regulatory scrutiny, which can increase our exposure to government investigations, legal actions, and penalties. Although we have policies, controls, and procedures designed to help ensure compliance with applicable laws, there can be no assurance that our employees, contractors, suppliers, or agents will not violate such laws or our policies. Violations of trade laws, restrictions, or regulations can result in fines; criminal sanctions against us or our officers, directors, or employees; prohibitions on the conduct of our business; and damage to our reputation.

We are subject to complex and rapidly changing import and export regulations of the countries in which we operate and/or sell which could limit our sales and decrease our profitability, and we may be subject to legal and regulatory consequences if we do not comply with applicable export control laws and regulations.

We are subject to the passage of and changes in the interpretation of regulation by U.S. and other government entities at the federal, state, and local levels and by non-U.S. agencies, including, but not limited to, the following:

•We are required to comply with import laws and export control and economic sanctions laws, which may affect our ability to enter into or complete transactions with certain customers, business partners, and other persons. In certain circumstances, export control and economic sanctions laws may prohibit the export of certain products, services, and technologies. We may be required to obtain an export license before exporting a controlled item, and granting of a required license cannot be assured. Compliance with the import laws that apply to our businesses may restrict our access to, and may increase the cost of obtaining, certain products and could interrupt our supply of imported inventory.

•Exported technologies, including, but not limited to, equipment necessary to develop and manufacture certain products are subject to U.S. export control laws and similar laws of other jurisdictions. We may be subject to adverse regulatory consequences, including government oversight of facilities and export transactions, monetary penalties, and other sanctions for any violations of these laws. In certain instances, these regulations may prohibit us from developing or manufacturing certain of our products for specific applications outside the United States. Failure to comply with any of these laws and regulations could result in civil and criminal, monetary, and nonmonetary penalties; disruptions to our business; limitations on our ability to import and export products and services; and damage to our reputation.

Obtaining export licenses can be difficult, time-consuming and require interpretation of complex regulations. Failure to obtain and/or retain export licenses for these shipments could significantly reduce our revenue and materially adversely affect our business, financial condition, results of operations and relationships with our customers.

Additionally, failure to comply with the various regulatory requirements could subject us to significant fines, suspension of export privileges or debarment. BIS has issued final rules that restrict access by Huawei to items produced domestically and abroad from certain U.S. technology, software, and equipment. These rules prevent us from selling certain products subject to the EAR to identified Huawei entities without a license issued by BIS.

In January 2025, we received an inquiry from BIS concerning past product sales to Huawei; we are cooperating with BIS’s inquiry and conducting an internal review of those sales to determine what products are subject to the EAR and consequently

24

restricted for export, reexport, and transfer when Huawei is a party to the transaction. We have stopped shipping products to Huawei, and we are in discussions with BIS regarding past product sales. At this time, we cannot predict the outcome of these discussions; cannot determine an estimate or range of loss; and we may be required to incur significant penalties and/or costs or expense as a result of the inquiry and to comply with, or to remedy any violations of, these regulations.

We are subject to a variety of complex and evolving laws, regulations, or industry standards, including with respect to environmental, health, safety, and product considerations, which may have a material adverse effect on our business, results of operations, or financial condition.

The manufacture of our products requires the use of facilities, equipment, chemicals, and materials that are subject to a broad array of laws and regulations in numerous jurisdictions in which we operate. Additionally, we are subject to a variety of other laws and regulations relative to the maintenance and operations of our facilities. Any changes in laws, regulations, or industry standards could cause us to incur additional direct costs, as well as increased indirect costs related to our relationships with our customers and suppliers, and otherwise harm our operations and financial condition. Any failure to comply with laws, regulations, or industry standards could adversely impact our reputation and our financial results.

New and evolving environmental health, safety, and product considerations, including those related to greenhouse gas emissions and climate change, the purchase, use and disposal of regulated and/or hazardous chemicals, and the potential resulting environmental, health or safety impacts, may result in new laws, regulations, or industry standards that may affect us, our suppliers, and our customers. Such laws, regulations, or industry standards could cause us to incur additional direct costs for compliance, as well as increased indirect costs resulting from our customers, suppliers, or both incurring additional compliance costs that are passed on to us. These costs may adversely impact our results of operations and financial condition.

New and evolving laws and regulations relating to cybersecurity, data privacy, and AI impose requirements for information confidentiality, integrity, availability, personal and proprietary data collection, storage, use, sharing, deletion, and AI solutions that must be safe, transparent, fair, secure, human-focused, and accountable. Such laws, standards, and market expectations could cause us to incur additional direct costs for compliance, as well as increased indirect costs resulting from our customers, suppliers, or partners reluctance to share information or solutions due to actual or perceived inadequate controls. These costs may adversely impact our operations and financial condition.

As a result of the considerations detailed in this risk factor, we could experience the following:

•suspension of production or sales of our products;

•limited supplies of chemicals or materials used to make our products;

•remediation costs;

•increased compliance costs;

•alteration of our manufacturing processes;

•regulatory penalties, fines, civil or criminal sanctions, and other legal liabilities; and

•reputational challenges.

Compliance with or our failure to comply with, laws, regulations, or industry standards could have a material adverse effect on our business, results of operations, or financial condition.

Our operations are subject to environmental, health and safety risks and requirements which could adversely affect our business, results of operations and reputation.

Our operations involve inherent environmental, health and safety risks, including those arising from the use or generation of certain hazardous materials in the development and manufacturing of our products. Such risks cannot be completely eliminated and human or environmental exposure to such hazardous materials may occur. Any such exposure could result in future third party claims against us, which could be time-consuming, costly and damaging to our business practices and reputation to litigate. Such exposures could also heighten regulatory scrutiny over our operations or require us to incur additional capital expenditures, either of which could have a material adverse impact on our business.

Additionally, our operations are subject to the requirements of federal, state and local environmental protection and occupational health and safety laws and regulations regulating issues such as the handling, use, storage and disposal of certain hazardous materials we use or generate. Environmental laws also impose obligations and liability for the cleanup of properties affected by hazardous substance spills or releases. The requirements of these laws and regulations are complex and we could become subject to potentially significant civil or criminal fines or penalties or liabilities arising from private rights of action if we fail to comply with any of these requirements. We have made and will continue to make substantial capital and other expenditures in order to comply with these laws and regulations. If any governmental authorities were to impose new environmental regulations requiring compliance in addition to that required by existing regulations or alter their interpretation of the requirements of such existing regulations, we may be subject to additional, and possibly substantial, costs, restrictions, or compliance procedures, which could materially and adversely impact our liquidity and results of operations.

25

Tax-related matters could have a material adverse effect on our business, results of operations, or financial condition.

We are subject to income taxes in the United States and many foreign jurisdictions. Our provision for income taxes and cash tax liabilities in the future could be adversely affected by numerous factors, including changes in the geographic mix of our earnings among jurisdictions, challenges by tax authorities to our tax positions and intercompany transfer pricing arrangements, failure to meet performance obligations with respect to tax incentive agreements, expanding our operations in various countries, fluctuations in foreign currency exchange rates, adverse resolution of audits and examinations of previously filed tax returns, and changes in tax laws and regulations.

Changes to income tax laws and regulations, or the interpretation of such laws, in any of the jurisdictions in which we operate could significantly increase our effective tax rate and ultimately reduce our cash flows from operating activities and otherwise have a material adverse effect on our financial condition. Further changes in the tax laws of foreign jurisdictions could arise as a result of the base erosion and profit shifting project, including Pillar Two Model Rules (“Pillar Two”), undertaken by the Organization for Economic Co-operation and Development (“OECD”). Nearly all European Union member states have enacted the Pillar Two legislation.

Risks Related to Capitalization and Financial Markets

Foreign currency risk may negatively affect our revenues, cost of sales, and operating margins, and could result in foreign exchange losses.

We conduct our business and incur costs in the local currency of most countries in which we operate. We incur currency transaction risk whenever one of our operating subsidiaries enters into either a purchase or a sales transaction using a different currency from the currency in which it operates, or holds assets or liabilities in a currency different from its functional currency. Changes in exchange rates can also affect our results of operations when the value of sales and expenses of foreign subsidiaries are translated to U.S. dollars. We cannot accurately predict the impact of future exchange rate fluctuations on our results of operations. Further, given the volatility of exchange rates, we may not be able to effectively manage our currency risks, and any volatility in currency exchange rates may increase the price of our products in local currency to our foreign customers or increase the manufacturing cost of our products, either of which may have an adverse effect on our financial condition, cash flows, and profitability. We may incur losses related to foreign currency fluctuations, and foreign exchange controls may prevent us from repatriating cash in countries outside the United States.

We have a substantial amount of debt, which could adversely affect our business, financial condition, or results of operations and prevent us from fulfilling our debt-related obligations.

As of June 30, 2025, we had approximately $3.7 billion of outstanding indebtedness on a consolidated basis, including under (i) our $850 million senior secured term loan A facility (the “Term A Facility”), (ii) our $2.8 billion senior secured term loan B facility (the “Term Loan B Facility”, and together with the Term A Facility, the “Senior Credit Facilities”) and (iii) our $990 million 5.000% senior notes due 2029 (the “2029 Notes”). Additionally, we have $315 million of undrawn capacity under our senior secured revolving credit facility (the “Revolving Credit Facility”). We may also incur additional indebtedness in the future by entering into new financing arrangements. Our indebtedness could have important consequences for us, including:

•making it difficult for us to satisfy all of our obligations with respect to our debt, or to our trade or other creditors;

•increasing our vulnerability to adverse economic or industry conditions;

•limiting our ability to obtain additional financing to fund capital expenditures and acquisitions, particularly when the availability of financing in the capital markets is limited;

•requiring us to pay higher interest rates upon refinancing or on our variable-rate indebtedness if interest rates rise;

•requiring a substantial portion of our cash flows from operations and the proceeds of any capital markets offerings or loan borrowings for the payment of interest on our debt and reducing our ability to use our cash flows to fund working capital, capital expenditures, acquisitions, and general corporate requirements;

•limiting our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate; and

•placing us at a competitive disadvantage to less leveraged competitors.

We may not generate sufficient cash flow from operations, together with any future borrowings, to enable us to pay our indebtedness or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, on or before its maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms or at all. In addition, we may incur additional indebtedness in order to finance our operations, fund acquisitions, or repay existing indebtedness. If we cannot service our indebtedness, we may have to take actions such as selling assets, pursuing sales of additional debt or equity securities, or reducing or delaying capital expenditures, strategic acquisitions, investments, or alliances. Any such actions, if necessary, may not be able to be effected on commercially reasonable terms or at all, or on terms that would be advantageous to our stockholders, or on terms that would not require us to breach the terms and conditions of our existing or future debt agreements.

26

The agreements that govern our senior credit facilities and our 5.000% senior notes due 2029 contain various covenants that impose restrictions on our business, which may affect our ability to operate our businesses.

The Credit Agreement and the Indenture, dated as of December 10, 2021 (as amended, restated, supplemented and/or otherwise modified from time to time, the “Indenture”), which provides for the 2029 Notes, contain various affirmative and negative covenants that will, subject to certain significant exceptions, restrict our ability to, among other things, have liens on our property, incur additional indebtedness, enter into sale and lease-back transactions, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, and/or merge or consolidate with any other person or sell or convey certain of our assets to any one person, among other things.

In addition, the Term Loan A Facility and Revolving Credit Facility require that the Company maintain (i) a maximum total net leverage ratio, as defined in the New Credit Agreement, of 4.00 to 1.00 from December 31, 2023 through maturity and (ii) an interest coverage ratio, as defined in the Credit Agreement, of at least 2.50 to 1.00.

Our ability to comply with these provisions may be affected by events beyond our control. Failure to comply with these covenants could result in an event of default, which, if not cured or waived, could accelerate our repayment obligations under the Credit Agreement or the Indenture, as applicable. If such indebtedness is accelerated, there can be no assurance that we will have sufficient financial resources or that we will be able to arrange financing to repay our borrowings at such time. If we are unable to repay the amounts due and payable under the Credit Agreement, those lenders could proceed against the collateral granted to them to secure that indebtedness, which could force us into bankruptcy or liquidation. As a result of these restrictions, we may be limited in how we conduct business, unable to raise additional debt or equity financing to operate during general economic or business downturns, or unable to compete effectively or to take advantage of new business opportunities.

In addition, we may enter into other credit agreements or other debt arrangements from time to time which contain similar or more extensive restrictive covenants and events of default, in which case we may face similar or additional limitations as a result of the terms of those credit agreements or other debt arrangements.

Any inability to access financial markets from time to time to raise required capital, finance our working capital requirements or our acquisition strategies, or otherwise support our liquidity needs could negatively impact our ability to finance our operations, meet certain obligations, or implement our growth strategy.

We from time to time borrow under our existing credit facility or use proceeds from sales of our securities to fund portions of our operations, including working capital investments and financing of our acquisition strategies. In the past, market disruptions experienced in the United States and abroad have materially impacted liquidity in the credit and debt markets, making financing terms for borrowers less attractive and, in certain cases, have resulted in the unavailability of certain types of financing. Uncertainty in the financial markets may negatively impact our ability to access additional financing or to refinance our existing debt arrangements on favorable terms or at all, which could negatively affect our ability to fund current and future expansion as well as future acquisitions and development. These disruptions may include turmoil in the financial services industry, volatility in the markets where our outstanding securities trade, and changes in general economic conditions in the areas where we do business. If we are unable to access funds at competitive rates, or if our short-term or long-term borrowing costs increase, our ability to finance our operations, meet our short-term obligations, and implement our operating strategies could be adversely affected.

In the future, we may be required to raise additional capital through public or private financing or other arrangements. Such financing may not be available on acceptable terms or at all, and our failure to raise capital when needed could harm our business and prospects. Additional equity financing may be dilutive to the holders of our outstanding capital stock, and debt financing, if available, may involve restrictive covenants that may limit our ability to undertake certain activities that we otherwise would find to be desirable. Further, debt service obligations associated with any debt financing could reduce our profitability. If we cannot raise funds on acceptable terms, we may not be able to grow our business or respond to competitive pressures.

The trading price of our common stock has been, and may continue to be, volatile.

Our common stock has experienced substantial price volatility in the past and may continue to do so in the future. Additionally, we, the technology industry, and the stock market as a whole have on occasion experienced extreme stock price and volume fluctuations that have affected stock prices in ways that may have been unrelated to the specific operating performance of individual companies. The trading price of our common stock may fluctuate widely due to various factors, including, but not limited to, actual or anticipated fluctuations in our financial condition and operating results, changes in financial forecasts or estimates by us or financial or other market estimates and ratings by securities and other analysts, changes in our capital structure, including issuance of additional debt or equity to the public, interest rate changes, regulatory changes, news regarding our products or products of our competitors, and broad market and industry fluctuations.

For these reasons, investors should not rely on recent or historical trends to predict future trading prices of our common stock, financial condition, results of operations, or cash flows. Investors in our common stock may not realize any return on their

27

investment in us and may lose some or all of their investment. Volatility in the trading price of our common stock could also result in the filing of securities class action litigation matters, which could result in substantial costs and the diversion of management time and resources.

Provisions in our Amended and Restated Articles of Incorporation and Amended and Restated Bylaws and the Pennsylvania Associations Code (the “Code”) may delay or prevent our acquisition by a third party, which could also reduce the market price of our capital stock.

Our Articles of Incorporation and Bylaws contain provisions that could make us a less attractive target for a hostile takeover and could make more difficult or discourage a merger proposal, a tender offer, or a proxy contest. Such provisions include:

•a requirement that shareholder-nominated director nominees be nominated in advance of the meeting at which directors are elected and that specific information be provided in connection with such nomination;

•the ability of our Board of Directors to issue additional shares of common stock or preferred stock without shareholder approval; and

•certain provisions requiring supermajority approval (at least two-thirds of the votes cast by all shareholders entitled to vote thereon, voting together as a single class).

In addition, the Code contains provisions that may have the effect of delaying or preventing a change in our control or changes in our management. Many of these provisions are triggered if any person or group acquires, or discloses the intent to acquire, 20% or more of a corporation’s voting power, subject to certain exceptions. These provisions:

•provide the other shareholders of the corporation with certain rights against the acquiring group or person;

•prohibit the corporation from engaging in a broad range of business combinations with the acquiring group or person;

•restrict the voting and other rights of the acquiring group or person; and

•provide that certain profits realized by the acquiring group or person from the sale of our equity securities belong to and are recoverable by us.

Regardless of the amount of a person’s holdings, if a shareholder or shareholder group (including affiliated persons) would be a party to certain proposed transactions with us or would be treated differently from other shareholders of ours in certain proposed transactions, the Code requires approval by a majority of votes entitled to be cast by all shareholders other than the interested shareholder or affiliate group, unless the transaction is approved by independent directors or other criteria are satisfied. Furthermore, under the Code, a “short-form” merger of Coherent Corp. cannot be implemented without the consent of our Board of Directors.

In addition, as permitted by Pennsylvania law, an amendment to our Articles of Incorporation or other corporate action that is approved by shareholders may provide mandatory special treatment for specified groups of nonconsenting shareholders of the same class. For example, an amendment to our Articles of Incorporation or other corporate action may provide that shares of common stock held by designated shareholders of record must be cashed out at a price determined by the Company, subject to applicable dissenters’ rights.

Furthermore, the Code provides that directors, in discharging their duties, may consider, to the extent they deem appropriate, the effects of any action upon shareholders, employees, suppliers, customers, and the communities in which the corporation’s offices are located. Directors are not required to consider the interests of shareholders to a greater degree than other constituencies’ interests. The Code expressly provides that directors do not violate their fiduciary duties solely by relying on “poison pills” or the anti-takeover provisions of the Code. We do not currently have a “poison pill.”

All of these provisions may limit the price that investors may be willing to pay for shares of our capital stock.

In addition, if any of certain fundamental changes were to occur, we or the surviving entity would be required to make an offer to repurchase, at the option and election of the holders thereof, for cash each share of Series B Preferred Stock then outstanding. These features of the Series B Preferred Stock could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.

Our ability to declare and pay dividends on our capital stock may be limited, including by the terms of our existing Credit Agreement.

Our declaration and payment of dividends on our capital stock in the future will be determined by our Board of Directors (or an authorized committee thereof) in its sole discretion and will depend on our financial condition, earnings, growth prospects, other uses of cash, funding requirements, applicable Pennsylvania law, and other factors our Board of Directors deems relevant.

The terms of the Credit Agreement contain a restriction on our ability to pay cash dividends on our capital stock. Credit facilities, indentures, or other financing agreements that we enter into in the future also may contain provisions that restrict or prohibit our ability to pay cash dividends on our capital stock.

28

In addition, under Pennsylvania law, our Board of Directors may not pay dividends if after giving effect to the relevant dividend payment we (i) would not be able to pay our debts as they become due in the usual course of our business or (ii) our total assets would not be greater than or equal to the sum of our total liabilities plus the amount that would be needed if we were to be dissolved at the time as of which the dividend is measured, in order to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the dividend.

Our common stock is subordinate to our existing and future indebtedness, the Series B Preferred Stock, and any other preferred stock we may issue in the future. Our Series B Preferred Stock ranks junior to all of our and our subsidiaries’ consolidated liabilities.

Shares of our common stock are equity interests that rank junior to all indebtedness and other non-equity claims on us with respect to assets available to satisfy our claims, including in a liquidation of the Company. Additionally, holders of our common stock may be subject to prior dividend and liquidation rights of any holders of our preferred stock or depositary shares representing such preferred stock then outstanding.

Our common stock ranks junior to our Series B Preferred Stock with respect to the payment of dividends and amounts payable in the event of our liquidation, dissolution, or winding-up of our affairs. This means that, unless accumulated dividends have been paid on all the Series B Preferred Stock then outstanding through the most recently completed dividend period, no dividends may be declared or paid on our common stock and we will not be permitted to repurchase any of our common stock, subject to limited exceptions. Likewise, in the event of our voluntary or involuntary liquidation, dissolution, or winding-up of our affairs, no distribution of our assets may be made to holders of our common stock until we have paid to holders of the Series B Preferred Stock then outstanding the applicable liquidation preferences.

In the event of a bankruptcy, liquidation, dissolution, or winding-up of our affairs, our assets will be available to pay obligations on the Series B Preferred Stock only after all of our consolidated liabilities have been paid. In addition, the Series B Preferred Stock ranks structurally junior to all existing and future liabilities of our subsidiaries. In the event of a bankruptcy, liquidation, dissolution, or winding-up of our affairs, there may not be sufficient assets remaining, after paying our and our subsidiaries’ liabilities, to pay amounts due on any or all of the Series B Preferred Stock then outstanding.

Our Board of Directors can issue, without approval of the holders of our common stock, preferred stock with voting and conversion rights that could adversely affect the voting power of the holders of our common stock, the rights of holders of shares of our capital stock, or the market price of our capital stock.

Our Articles of Incorporation authorize our Board of Directors to issue one or more additional series of preferred stock and set the terms of the preferred stock without seeking any further approval from our shareholders. Any preferred stock that is issued will rank ahead of our common stock in terms of dividends and liquidation rights. If we issue additional preferred stock, it may adversely affect the market price of our common stock. Our Board of Directors also has the authority, without shareholder approval, subject to applicable law, to set the terms of any such series of preferred stock that may be issued, including voting rights, dividend rights, preferences over our common stock with respect to dividends, and other terms, or upon our liquidation, dissolution, or winding-up of our affairs. If we issue additional preferred stock in the future that has a preference over our common stock with respect to the payment of dividends or upon our liquidation, dissolution, or winding-up of our affairs, or if we issue additional preferred stock with voting rights that dilute the voting power of our common stock, the rights of holders of our capital stock or the market price of our capital stock could be adversely affected. The issuance of preferred stock or even the ability to issue preferred stock could also have the effect of delaying, deterring, or preventing a change of control or other corporate action.

The redemption rights of the holders of Series B Preferred Stock may result in the use of our cash in such a way that could adversely affect our business, financial condition or results of operations.

At any time on or after the ten-year anniversary of the applicable issuance date of the shares of our Series B Preferred Stock and subject to the procedures set forth in the terms of the Series B Preferred Stock, each holder of such shares will have the right to require us to redeem all of such holder’s shares for cash at a price per share equal to the sum of the applicable stated value for such shares plus accrued or declared and unpaid dividends on such shares that had not previously been added to such stated value. This may have the effect of reducing funds available for working capital, capital expenditures, acquisitions and other general corporate purposes, thereby negatively affecting the interests of holders of our other capital stock, including our common stock.

Holders of our Series B Preferred Stock can exercise significant control over us, which could limit the ability of holders of our other capital stock to influence the outcome of key transactions, including a change of control.

Our Series B Preferred Stock has voting rights, allowing holders to vote as one class with our common stock on an as-converted basis, subject to limited exceptions. As a result, the holders of Series B Preferred Stock have the ability to significantly influence the outcome of any matter submitted for the vote of the holders of our common stock. Holders of Series B Preferred Stock are entitled to act separately in their own respective interests with respect to their ownership interests in us and have the

29

ability to substantially influence all matters that require approval by our shareholders, including the approval of significant corporate transactions. Additionally, we may not undertake certain actions without the prior written approval of the holders of a majority of the issued and outstanding shares of Series B Preferred Stock, voting separately from our common stock. Subject to certain exceptions, we must not: (1) alter or change the rights, preferences or privileges of our Series B Preferred Stock or amend, modify or supplement any provision of our organizational documents in a manner that adversely affects the rights, powers, preferences or privileges of our Series B Preferred Stock; (2) authorize or issue any senior stock (or securities convertible into senior stock), or amend or alter our articles of incorporation to increase the number of authorized or issued shares of our Series B Preferred Stock; (3) decrease the number of authorized shares of our Series B Preferred Stock (other than as permitted pursuant to a conversion, redemption or repurchase by us thereof); (4) issue any shares of our Series B Preferred Stock (other than pursuant to the amended and restated invested agreement, entered into on March 30, 2021, by and between Bain Capital Private Equity, LP (“BCPE”) and us (the “Investment Agreement”)); and (5) effect any voluntary deregistration or delisting with the NYSE of our common stock.

Furthermore, we may not, unless holders of Series B Preferred Stock otherwise consent in writing (or if such action is taken with respect to a Permitted Issuance (as defined in the Investment Agreement)), so long as BCPE owns at least 5% of the number of shares of Series B Preferred Stock that it held immediately following the issuance and sale of the Series B-2 Preferred Stock upon completion of our acquisition of Coherent, Inc., (i) authorize or issue any parity stock and (ii) pay any cash dividend on our common stock (other than ordinary dividends). We also may not, unless BCPE otherwise consents in writing (or if such action is taken with respect to a Permitted Issuance (as defined in the Investment Agreement)), so long as it owns at least 25% of the number of shares of Series B Preferred Stock that it held immediately following the issuance and sale of the Series B-2 Preferred Stock upon completion of our acquisition of Coherent, Inc., redeem, repurchase or otherwise acquire (or make or declare any dividend or distribution in respect of) any junior stock (subject to certain exceptions, including, among other things, ordinary dividends, non-cash dividends or other distributions paid pro rata to all holders of our common stock and, if applicable, holders of Series B Preferred Stock, repurchases of junior stock of up to $100 million on an aggregate annual basis and dividends on junior stock in kind or in the form of other junior securities or securities convertible into or exchange for such junior securities). Moreover, under the terms of the Investment Agreement, following the closing of the initial investment and for so long as BCPE beneficially owns shares of Series B Preferred Stock (or shares of our common stock issued upon the conversion thereof) that represent, in the aggregate and on an as-converted basis, at least 25% of the number of shares of Series B Preferred Stock that it held immediately following the completion of the issuance and sale of the Series B-2 Preferred Stock upon completion of our acquisition of Coherent, Inc., BCPE will have the right to nominate one designee and to designate one observer to the our Board of Directors. Circumstances may occur in which the interests of BCPE could conflict with the interests of holders of other outstanding capital stock, including our common stock.

Item 1C.    CYBERSECURITY

Risk Management and Strategy

We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats and have integrated these processes into our overall risk management systems and processes. We have aligned our cybersecurity program with recognized security frameworks such as NIST-CSF (National Institute of Standard and Technologies – Cybersecurity Framework). We routinely assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing therein.

We maintain a risk based approach to identify cybersecurity threats, and conduct assessments to determine if our information systems are vulnerable to such cybersecurity threats. This includes identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks.

We maintain reasonable safeguards to minimize identified risks; reasonably address any identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards. We devote significant resources and designate high-level personnel, including our Chief Information Officer and Global Head of Cybersecurity, to manage the risk mitigation process.

We have implemented technical solutions that are designed to protect our information systems from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality, and access controls. We regularly evaluate, monitor, and improve these solutions. As part of our overall risk management system, we monitor and test our safeguards and train our employees on these safeguards, in collaboration with human resources, information technology, legal, compliance and ethics and management. Personnel at all levels and departments are made aware of our cybersecurity policies through periodic trainings.

We periodically engage consultants, auditors, or other third parties. These service providers assist us to design, implement or assess our cybersecurity policies and procedures, as well as to monitor and test our safeguards. We work with our third-party suppliers and service providers to address the use of appropriate security measures in connection with their work with us.

Like any other technology company operating in today’s environment, we have experienced cybersecurity incidents in the past and may experience them in the future. However, we have not experienced any cybersecurity incidents that have been determined to be material. For additional information regarding risks from cybersecurity threats, and their effect on our company, including our business strategy, results of operations, or financial condition, please refer to “Item 1A. Risk Factors – Risks Related to Our Business, Operations, and Industry – Cybersecurity attacks and incidents and other vulnerabilities could subject us to costly damages, claims and expenses, harm to our reputation or competitive position, or disrupt our operations and business.”

Governance

One of the key functions of our Board of Directors is informed oversight of our risk management process, including risks from cyber security threats. Our Board of Directors is responsible for monitoring and assessing strategic risk exposure, and our executive officers are responsible for the day-to-day management of the material risks we face. Our Board of Directors administers its cybersecurity risk oversight function through the Nominating and Corporate Governance (“NCG”) Committee.

The NCG Committee is briefed quarterly by management on, among other things, our company’s cybersecurity risks and activities, including any recent cybersecurity incidents and related responses, cybersecurity systems testing, activities of third parties, and the like. The NCG Committee provides regular updates to the Board of Directors on such reports.

Our Chief Information Officer and Global Head of Cybersecurity have combined relevant experience of more than 45 years, including over 20 years in cybersecurity, and they oversee our cyber security policies and processes, including those described in “Risk Management and Strategy” above. Our Global Head of Cybersecurity monitors and keeps informed about prevention, detection, mitigation, and remediation efforts through regular communication and reporting from our cybersecurity team, and through the use of technological tools and software and results from third party assessments.

PART II

Item 5.        MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

The Company’s common stock is traded on the New York Stock Exchange (the “NYSE”) under the symbol “COHR”, beginning February 23, 2023 when the Company voluntarily transferred the listing of its common stock from the NASDAQ Global Select Market to the NYSE. As of August 11, 2025, there were approximately 790 holders of record of our common stock. The Company historically has not paid cash dividends on its common stock and does not presently anticipate paying cash dividends on its common stock in the future.

Dividends on the Company’s Series A Mandatory Convertible Preferred Stock were payable on a cumulative basis when, as and if declared by our Board of Directors, or an authorized committee of our Board of Directors, at an annual rate of 6% of the liquidation preference of $200.00 per share. All outstanding shares of Series A Mandatory Convertible Preferred Stock were converted to Company Common Stock on July 3, 2023, and no shares of Series A Mandatory Convertible Preferred Stock are currently issued and outstanding.

Dividends on the Company’s Series B Convertible Preferred Stock will be payable on a cumulative basis when, as and if declared by our Board of Directors, or an authorized committee of our Board of Directors, at an annual rate of 5%, subject to increase if Coherent defaults on its payment obligation with respect to these shares, not to exceed 14% per annum. Until the fourth anniversary of the issuance of the Series B Convertible Preferred Stock, dividends are payable solely in-kind. After the fourth anniversary, dividends are payable, at the Company’s option, in cash, in-kind or as a combination of both. Dividends of $11 million on our Series B-1 Convertible Preferred Stock were paid in cash in the fourth quarter of fiscal 2025.

ISSUER PURCHASES OF EQUITY SECURITIES

The Company did not repurchase any shares of its common stock during the fiscal year ended June 30, 2025, and no stock repurchase program was in effect during the period.

Overview

For an overview of our business, see Part I - Item 1. Business - General Description of Business of this Annual Report on Form 10-K for further information.

Trends and Other Matters Affecting our Business

Industry Conditions

Throughout fiscal 2025, we experienced stronger demand in our Communications market. The increase in the number of hyperscale and other cloud customers building AI datacenters and in the number and size of their AI datacenter buildouts drove demand for our datacenter transceivers. Strong demand for our new ZR/ZR+ transceiver products along with growing demand for traditional telecom transport products drove increased volumes for our telecom and other communications solutions.

Additionally, within our Industrial market, we were able to grow our industrial lasers products and services revenue in the face of relatively weak overall industrial end demand. Our revenue growth in these portions of the Industrial market is a result of our focus on higher demand applications within the Industrial market, including display and semiconductor capital equipment.

Restructuring Plans

2023 Plan

On May 23, 2023, the Board of Directors approved the 2023 Plan which includes site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. These restructuring actions were intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model.

In fiscal 2025, these activities resulted in charges of $53 million, primarily for impairment losses associated with the sale of our Newton Aycliffe business, impairment of right-of-use (“ROU”) assets, employee termination costs, site move costs and accelerated depreciation. In fiscal 2024, these activities resulted in charges of $27 million, primarily for accelerated depreciation, the write-off of property and equipment, and site move costs. In fiscal 2023, these activities resulted in $119 million of charges primarily for employee termination costs, and the write-off of property and equipment, net of $65 million from reimbursement arrangements. See Note 20. Restructuring Plans to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

2025 Plan

Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of the Company’s business, the Company’s management approved the 2025 Plan to take a number of restructuring actions, including site consolidations, facilities moves and closures, workforce reductions, contract terminations, and certain other associated cost reductions.

In fiscal 2025, these activities resulted in $107 million of charges primarily for the write-off of property and equipment and ROU assets, employee and contract termination costs. We expect the restructuring actions to be substantially completed by the

35

end of fiscal 2026. However, the actual timing and costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material.

Synergy and Site Consolidation Plan

On May 20, 2023, the Company announced that it had accelerated some of the actions planned as part of its multi-year synergy and site consolidation efforts following the acquisition of Coherent, Inc., including site consolidations and relocations to lower cost sites. These relocations and other actions resulted in the Company achieving its previously announced $250 million synergy plan, which included savings from supply chain management, internal supply of enabling materials and components, operational efficiencies in all functions due to scale, global functional model efficiencies and consolidation of corporate costs. In fiscal 2025, the acceleration of these activities resulted in $17 million of charges primarily for overlapping labor related to transition of manufacturing operations to other sites, shut down costs and employee termination costs. In fiscal 2024, the acceleration of these activities resulted in $40 million of charges primarily for overlapping labor related to transition of manufacturing operations to other sites, shut down costs for sites being exited, accelerated depreciation and employee termination costs. In fiscal 2023, the acceleration of these activities resulted in $20 million in charges primarily for employee termination costs, the write-off of inventory for products that have been exited and shut down costs.

Impairment of Assets Held-for-Sale

In the fourth quarter of fiscal 2025, management entered into non-binding agreements to sell several entities. As a result of classifying these entities as held-for-sale, we recorded non-cash impairment charges of $85 million to Impairment of assets held-for-sale in our Consolidated Statements of Earnings (Loss) in the fourth quarter of fiscal 2025 to reduce our carrying value in these entities to fair value. See Note 21. Assets Held-for-Sale to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Macroeconomic Conditions - Tariffs

In early 2025, the United States implemented significant new tariffs on foreign imports impacting multiple countries, commodities and industries, and these new tariffs and export restrictions also prompted retaliatory tariffs and export restrictions from certain countries. As of June 2025, certain tariffs and retaliatory tariffs have been delayed, but a number of the new tariffs remain in effect, including significant tariffs and trade sanctions between the United States and China. China has also restricted the export of certain rare earth minerals which are used in our products.

These tariffs, trade sanctions, and/or restrictions on the export of certain rare earth minerals which are used in our products did not have a material impact on our business, financial condition, operational results and/or cash flows in fiscal 2025 nor do we expect them to have a material impact on our business, financial condition, operational results and/or cash flows in fiscal 2026.

As a global company with a substantial and diversified manufacturing footprint our diverse manufacturing footprint provides us with some insulation against these tariffs, trade sanctions, and other geopolitical challenges. Our geographically diverse supply chain combined with the internal production of many of our most critical technology in-feeds provides adaptability and optionality that benefits our customers. As the tariff, trade sanctions, and export restrictions become more clear, we expect these attributes will enable us to find opportunities to moderate their impact. However, we are in a dynamic geopolitical environment, and we are not immune to any sustained disruption in global trade conditions which may create future headwinds for the Company and could result in revenue reduction, cost increases on material used in our products or significant production delays, which could adversely affect our business, financial condition, operational results and cash flows.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its Consolidated Financial Statements and accompanying notes. Note 1. Nature of Business and Summary of Significant Accounting Policies, of the Notes to our Consolidated Financial Statements contained in Item 8 of this Annual Report on Form 10-K, describes the significant accounting policies and accounting methods used in the preparation of the Company’s Consolidated Financial Statements. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates.

Management has discussed the development and selection of the critical accounting policies and estimates described below with the Audit Committee of the Board of Directors and the Audit Committee has reviewed the related disclosure. In addition, there are other items within our Consolidated Financial Statements that require estimation but are not deemed critical. Changes in estimates used in these and other items could impact the Consolidated Financial Statements.

36

Goodwill

We test goodwill for impairment annually, and when events or changes in circumstances indicate that goodwill might be impaired. The determination of whether goodwill is impaired requires us to make judgments based on long-term projections of future performance. Estimates of fair value are based on our projection of revenues, operating costs and cash flows of each reporting unit, considering historical and anticipated results and general economic and market conditions and their projections. For fiscal year 2025, we performed a quantitative assessment. The fair values of the reporting units were determined using a discounted cash flow analysis with projected financial information based on our most recently completed long-term strategic planning processes and also considers the current financial performance compared to our prior projections of the reporting units, as well as a market analysis. Determination of the fair value requires discretion and the use of estimates by management. If actual results are not consistent with management’s estimates and assumptions, a material goodwill impairment charge could occur, which could have a material adverse effect on our consolidated financial statements.

Due to the cyclical nature of our business, and the other factors described in the section on Risk Factors set forth in Item 1A of this Annual Report on Form 10-K, the profitability of our individual reporting units may periodically be affected by downturns in customer demand, operational challenges and other factors. If material adverse conditions occur that impact one or more of our reporting units, our determination of future fair value might not support the carrying amount of one or more of our reporting units, and the related goodwill would need to be impaired. We will continue to monitor any changes to our assumptions and will evaluate goodwill as deemed warranted during future periods.

Income Taxes

The Company prepares and files tax returns based on its interpretation of tax laws and regulations and records estimates based on these judgments and interpretations. In the normal course of business, the Company’s tax returns are subject to examination by various taxing authorities, which may result in future tax, interest and penalty assessments by these authorities. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits is adjusted for changes in facts and circumstances. For example, adjustments could result from significant amendments to existing tax law and the issuance of regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company believes that its estimates for uncertain tax positions are appropriate and sufficient to pay assessments that may result from examinations of its tax returns. The Company recognizes both accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Management evaluates the realizability of deferred tax assets for each jurisdiction in which it operates. If the Company experiences cumulative pretax income in a particular jurisdiction in a three-year period including the current and prior two years, management normally concludes that the income tax assets will more likely than not be realizable and no valuation allowance is recognized, unless known or planned operating developments, or changes in tax laws, would lead management to conclude otherwise. However, if the Company experiences cumulative pretax losses in a particular jurisdiction in a three-year period, management then considers a series of factors in the determination of whether the deferred tax assets can be realized. The Company has recorded valuation allowances against certain of its deferred tax assets, primarily those that have been generated from net operating losses in certain foreign taxing jurisdictions and acquired U.S. carryforwards. In evaluating whether the Company would more likely than not recover these deferred tax assets, it has not assumed any future taxable income or tax planning strategies in the jurisdictions associated with these carryforwards where history does not support such an assumption. Implementation of tax planning strategies to recover these deferred tax assets or future income generation in these jurisdictions could lead to the reversal of these valuation allowances and a reduction of income tax expense.

The OECD, a global policy forum, introduced a framework to implement a global minimum tax of 15% which would apply to multinational corporations, referred to as Pillar Two. Nearly all OECD member jurisdictions have agreed in principle to adopt these provisions and numerous jurisdictions have enacted legislation, including jurisdictions where the Company operates, with a subset of the rules becoming effective for our fiscal year beginning on July 1, 2024, and the remaining rules becoming effective for our fiscal year beginning on July 1, 2025, or in later periods. The Company is continuing to analyze the Pillar Two rules as countries implement additional legislation. Implementation of the OECD proposal may have a material impact on the Company's Consolidated Financial Statements in the future.

Consolidated

Revenues. Revenues for the year ended June 30, 2025 increased 23% to $5,810 million, compared to $4,708 million for the prior fiscal year.

Revenues increased $1,162 million, or 51%, in the communications market, with increases in datacom driven primarily by ongoing strong AI datacenter demand and growth in our telecom revenue due to higher demand in the data center interconnect and the telecom transport markets. In our remaining markets, revenue decreased $60 million, or 2%. Within these markets, revenue growth in display capital equipment and in semiconductor capital equipment volumes was more than offset by soft demand due to the macroeconomic environment in broad-based industrial end markets, including decreases in demand in our Silicon Carbide business, which was consistent with softer end market demand in the automotive market.

From a segment perspective, Networking revenues increased $1,126 million year-over-year, due to strong AI datacenter demand in our communications market and the growth in telecom. Lasers revenue increased $40 million year-over-year reflecting higher volumes of annealing lasers in our display capital equipment market partially offset by continued soft demand in precision manufacturing. Materials decreased $63 million year-over-year, primarily due to softness in the Silicon Carbide business.

Gross margin. Gross margin for the year ended June 30, 2025 was $2,043 million, or 35%, of total revenues, compared to $1,456 million, or 31% of total revenues, for fiscal 2024, an increase of 424 basis points. The increase as a percent of revenue for fiscal 2025 was primarily due to higher revenue volume particularly in the communications market in the Networking segment, improvements in both pricing optimization and cost reductions, partially offset by unfavorable mix and foreign exchange impacts. Cost reductions included both lower manufacturing costs and improvements in manufacturing yields.

Research and development. Research and development (“R&D”) expenses for the fiscal year ended June 30, 2025 were $582 million, or 10% of revenues, compared to $479 million, or 10% of revenues, last fiscal year. The increase of $103 million for fiscal 2025 was primarily related to continued investment in our product portfolios, particularly in datacom. We continue to focus on investing our R&D in those projects with the highest return-on-investment.

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the year ended June 30, 2025 were $926 million, or 16% of revenues, compared to $854 million, or 18% of revenues, last fiscal year. The decrease in SG&A as a percentage of revenue for fiscal 2025 compared to fiscal 2024 was primarily the result of higher sales volumes and lower executive transition costs partially offset by the impact of higher variable and share-based compensation.

38

Restructuring charges. Restructuring charges for the year ended June 30, 2025 were $160 million, or 3% of revenues. The restructuring charges consisted primarily of asset write-offs, employee termination costs, move costs, contract termination costs and accelerated depreciation due to the consolidation and closure of certain manufacturing sites as well as impairment losses associated with the sale of our Newton Aycliffe business. Restructuring charges related to our 2023 Restructuring Plan for the year ended June 30, 2024 were $27 million, or 1% of revenues, and consisted primarily of severance, accelerated depreciation, equipment write-offs and move costs due to the consolidation of certain manufacturing sites. See Note 20. Restructuring Plans to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Impairment of assets held-for-sale. Impairment of assets held-for-sale for the year ended June 30, 2025 were $85 million, or 1% of revenues and represented non-cash impairment charges to reduce our carrying value in entities held-for-sale at June 30, 2025 to fair value. See Note 21. Assets Held-for-Sale to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Interest and other, net. Interest and other, net for the year ended June 30, 2025 was expense of $196 million compared to expense of $244 million last fiscal year, a decrease of $48 million. Included in Interest and other, net, were interest expense on borrowings, foreign currency gains and losses, amortization of debt issuance costs, equity gains and losses from unconsolidated investments, interest and dividend income on excess cash balances and income from an insurance settlement. The decrease of $48 million in comparison to fiscal 2024 was driven by driven by $45 million lower interest expense, $8 million higher interest income and $8 million higher income from insurance settlements partially offset by $19 million higher foreign exchange net losses. The $45 million lower interest expense was primarily due to lower interest expense on our New Term B Loans resulting from lower balances and lower interest rates partially offset by lower interest expense benefit from our interest rate cap and swap. The $8 million higher interest and dividend income is primarily due to increases in interest rates earned on investments as well as the increase in average restricted cash balances due to the timing of receipt from our investment in Silicon Carbide LLC in the second quarter of fiscal 2024. The $19 million higher foreign exchange net losses were primarily due to higher volatility of exchange rates, particularly the Euro, during fiscal 2025 in addition to the cessation of our balance sheet hedging program at the end of September 2024.

Income taxes. Our effective income tax rate for fiscal 2025 was 68%, compared to an effective tax rate of (8)% last fiscal year. The difference between our effective tax rate and the U.S. statutory rate of 21% was due to tax rate differentials between U.S. and foreign jurisdictions. The fiscal 2025 rate was impacted by the classification of assets held for sale and an increase in the U.S. valuation allowance.

Net loss attributable to noncontrolling interests. Net loss attributable to noncontrolling interests for the year ended June 30, 2025 was $19 million, compared to $3 million last fiscal year and represents the noncontrolling interest holders’ shares of losses of Silicon Carbide LLC. See Note 11. Noncontrolling Interests to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Segment Reporting

Revenues and segment profit for our reportable segments are discussed below. During the first quarter of fiscal 2025 as a result of a new CEO joining the Company in the fourth quarter of fiscal 2024, our Chief Operating Decision Maker (“CODM”) implemented changes in the measure he uses to allocate resources and assess performance. Our CODM now evaluates each segment’s performance and allocates resources based on segment revenue and segment profit, instead of operating income, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, impairment charges on assets held-for-sale, and certain other charges. Additionally, effective the first quarter of fiscal 2025, we no longer allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. Management believes segment profit to be a useful measure for investors, as it reflects the results of segment performance over which management has direct control and is used by management in its evaluation of segment performance. See Note 14. Segment and Geographic Reporting to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information on the Company’s reportable segments and for the reconciliation of the Company’s segment profit to earnings (loss) before income taxes, which is incorporated herein by reference.

Comparative prior year segment information has been recast to conform to the new segment profitability measure. The change in our operating segment measure had no impact on our previously reported consolidated results of operations, financial condition, or cash flows.

Networking ($ in millions)

	Year Ended June 30,				% Increase
	2025		2024
Revenues	$	3,421	$	2,296	49	%
Segment profit	$	644	$	354	82	%

Revenues for the year ended June 30, 2025 for Networking increased 49% to $3,421 million, compared to $2,296 million for last fiscal year. The increase in revenues of $1,125 million during fiscal 2025 was primarily due to increased AI datacenter related revenue in our communications market resulting from increased volumes in the datacom vertical and growth in the telecom vertical due to increased demand in data center interconnect and the telecom transport market.

Segment profit for the year ended June 30, 2025 for Networking increased 82% to $644 million, compared to segment profit of $354 million last fiscal year. The increase in segment profit for fiscal 2025 was driven by $1,125 million higher revenues partially offset by higher R&D investments in our product portfolio.

Consolidated

Revenues. Revenues for the year ended June 30, 2024 decreased 9% to $4,708 million, compared to $5,160 million for fiscal 2023.

Revenues decreased in all four markets, with the largest decline, $270 million, or 43%, in the electronics market, primarily from lower volumes in the consumer electronics vertical, largely due to a design change implemented by a significant electronics customer. Revenues decreased by $82 million, or 17% in the instrumentation market due to decreased volumes in the life sciences vertical from continued inventory digestion by our customers and in the industrial market by $81 million, or 5%, as a result of decreased shipments in the precision manufacturing vertical primarily due to macroeconomic conditions. In addition, revenues decreased $20 million, or 1%, in the communications market, primarily due to decreased volumes in the telecom vertical as our communications service provider customers continued to work down their inventory levels with reduced capital spending, partially offset by increased shipments in the datacom vertical driven by increased AI-related datacom shipments.

From a segment perspective, Materials decreased $333 million from fiscal 2023, primarily due to lower demand for sensing products and other consumer applications in the consumer electronics vertical within the electronics market for the reasons discussed above. Networking revenues decreased $45 million from fiscal 2023, with decreases from the telecom vertical partially offset by increases in the datacom vertical, both in our communications market, for the reasons discussed above. Lasers revenue decreased $74 million from fiscal 2023 due to lower demand in the life sciences vertical in the instrumentation market and to lower demand in the precision manufacturing and semiconductor and display capital equipment verticals in the industrial end market.

Gross margin. Gross margin for the year ended June 30, 2024 was $1,456 million, or 31%, of total revenues, compared to $1,618 million, or 31% of total revenues, for fiscal 2023, a slight decrease of 43 basis points. During fiscal 2023, the Company recorded $158 million in Cost of goods sold related to the fair value adjustment on acquired inventory from the acquisition of Coherent, Inc. (“Merger”). Gross margin, excluding the fair value adjustment on acquired inventory, decreased 349 basis points for fiscal 2024 compared to fiscal 2023 primarily due to lower revenues, less favorable sales mix especially in the datacom vertical in the communications market, underutilized operating capacity in several plants, shut down costs related to site consolidations, lower yields in the datacom vertical, higher costs related to product lines that are being exited, higher inventory provisions and the unfavorable foreign exchange rates.

Research and development. R&D expenses for the fiscal year ended June 30, 2024 were $479 million, or 10% of revenues, compared to $500 million, or 10% of revenues, for fiscal 2023. The decrease of $21 million for fiscal 2024 is due to all three segments and was driven by lower costs due to the consolidation of sites and our efforts to control costs. The R&D expenses are

41

primarily related to our continued investment in new products and platform technologies in an effort to accelerate our organic growth across all of our businesses, including significant investments in datacom transceivers for AI, indium phosphide and gallium arsenide semiconductor lasers, silicon carbide materials, and lasers for display processing, semiconductor capital equipment, and instrumentation.

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the year ended June 30, 2024 were $854 million, or 18% of revenues, compared to $1,037 million, or 20% of revenues, for fiscal 2023. The decrease in SG&A as a percentage of revenue for fiscal 2024 compared to fiscal 2023 was primarily the result of lower amortization expense of $117 million resulting from (1) the Merger, as backlog intangibles were fully amortized in fiscal 2023, (2) lower amortization for tradenames impaired in the fourth quarter of fiscal 2023, and (3) $31 million charges for impairment of certain tradename and customer list intangibles assets in fiscal 2023. In addition, SG&A decreased due to lower charges related to the Merger, including $39 million lower transaction fees and financing, and lower one-time expense of $18 million related to share-based compensation resulting from the Merger, as well as lower costs due to the consolidation of sites and our efforts to control costs, partially offset by the impact of lower revenues.

Restructuring Charges. Restructuring charges related to our 2023 Plan for the year ended June 30, 2024 were $27 million, or 1% of revenues, and consist primarily of accelerated depreciation, equipment write-offs and move costs due to the consolidation of certain manufacturing sites. Restructuring charges related to our 2023 Plan for the year ended June 30, 2023 were $119 million, or 2% of revenues, and consisted of severance and equipment write-offs, net of reimbursements, due to the consolidation of certain manufacturing sites. See Note 20. Restructuring Plans to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Interest and other, net. Interest and other, net for the year ended June 30, 2024 was expense of $244 million compared to expense of $318 million for fiscal 2023, a decrease of $75 million. Included in Interest and other, net, were interest expense on borrowings, Merger financing fees (fiscal 2023), foreign currency gains and losses, amortization of debt issuance costs, equity gains and losses from unconsolidated investments, and interest income on excess cash balances. The decrease of $75 million in comparison to fiscal 2023 was driven by driven by $39 million incremental interest and dividend income due to increases in interest and dividend rates earned on investments, as well as the increase in restricted cash balances and $35 million incurred in the prior year related to financing of the Merger. In addition, interest expense increased $2 million due to higher interest rates on our Term facilities, net of higher benefit from our interest rate cap and swap.

Income taxes. Our effective income tax rate for fiscal 2024 was (8)%, compared to an effective tax rate of 27% for fiscal 2023. The difference between our effective tax rate and the U.S. statutory rate of 21% was due to the establishment of a valuation allowance related to certain US deferred tax assets.

Net loss attributable to noncontrolling interests. Net loss attributable to noncontrolling interests for the year ended June 30, 2024 was $3 million, and represents the noncontrolling interest holders’ shares of losses of Silicon Carbide LLC after the close of the transaction on December 4, 2023. See Note 11. Noncontrolling Interests to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

Segment Reporting

For a discussion of revenues and segment profit measures, refer to our disclosure under “Segment Reporting” within “Fiscal Year 2025 Compared to Fiscal Year 2024” above.

Comparative prior year segment information has been recast to conform to the new segment profitability measure. The change in our operating segment measure had no impact on our previously reported consolidated results of operations, financial condition, or cash flows.

Networking ($ in millions)

	Year Ended June 30,				% Decrease
	2024		2023
Revenues	$	2,296	$	2,341	(2)	%
Segment profit	$	354	$	465	(24)	%

Revenues for the year ended June 30, 2024 for Networking decreased 2% to $2,296 million, compared to $2,341 million for fiscal year 2023. The decrease in revenues of $45 million during fiscal 2024 was primarily due to decreased volumes year-over-year in the telecom vertical as our communications service provider customers continue to work down their inventory levels with reduced capital spending, partially offset by increases in the datacom vertical driven by increased AI-related datacom transceivers shipments, both within the communications market.

42

Segment profit for the year ended June 30, 2024 for Networking decreased 24% to $354 million, compared to segment profit of $465 million for fiscal year 2023. The decrease in segment profit for fiscal 2024 was driven by $45 million lower revenues and lower margin percentage. The margin percentage was lower than fiscal 2023 due to less favorable sales mix in the datacom vertical, the impact of fixed manufacturing costs as a percentage of revenues on lower revenues in the telecom vertical, lower yields in the datacom vertical and higher inventory provisions related to products that are being exited.

Materials ($ in millions)

	Year Ended June 30,				% Decrease
	2024		2023
Revenues	$	1,017	$	1,350	(25)	%
Segment profit	$	297	$	392	(24)	%

Revenues for the fiscal year ended June 30, 2024 for Materials decreased 25% to $1,017 million, compared to revenues of $1,350 million for fiscal year 2023. The decrease in revenues during fiscal 2024 was primarily related to a decrease of $265 million in the electronics market mostly due to lower volumes in our consumer electronics vertical largely due to a design change implemented by a significant electronics customer, partially offset by higher shipments in our automotive vertical driven by electric vehicles, as well as decreases in shipments to a lesser extent derived from macroeconomic conditions in our precision manufacturing and semiconductor capital equipment verticals in the industrial market.

Segment profit for the fiscal year ended June 30, 2024 for Materials decreased 24%, with segment profit of $297 million in fiscal 2023, compared to segment profit of $392 million for fiscal year 2023. The decrease in segment profit during fiscal 2024 was driven by $333 million lower revenues and higher costs for sites being shutdown.

	2024		2023
Revenues	$	1,395	$	1,469	(5)%
Segment profit	$	207	$	271	(24)%

Revenues for the fiscal year ended June 30, 2024 for Lasers decreased 5% to $1,395 million, compared to revenues of $1,469 million for fiscal 2023. The decrease was primarily due to $56 million lower shipments to the instrumentation market, primarily in the life sciences vertical where we saw continued inventory digestion by our customers, and an $18 million drop in the industrial market as a result of lower volumes in our precision manufacturing and display capital equipment verticals due to macroeconomic conditions, partially offset by higher volumes in our semiconductor capital equipment display vertical.

Segment profit for the fiscal year ended June 30, 2024 for Lasers decreased 24%, with segment profit of $206.8 million in the current year, compared to segment profit of $270.6 million for fiscal 2023. The lower segment profit was driven by lower revenues and lower gross margin percentage, due to less favorable mix within the industrial and instrumentation markets, the unfavorable impact of fixed manufacturing costs with lower revenues and higher inventory provisions.

Liquidity and Capital Resources

Historically, our primary sources of cash have been provided from operations, long-term borrowings, and advance funding from customers.

Net cash provided by operating activities:

Net cash provided by operating activities was $634 million during the current fiscal year ended June 30, 2025 compared to $546 million of cash provided by operating activities during the same period last fiscal year. The increase in cash flows provided by operating activities during the year ended June 30, 2025 compared to the same period last fiscal year was primarily due to higher earnings partially offset by increases in accounts receivables and inventories as a result of higher revenues.

Net cash provided by operating activities was $546 million and $634 million for the fiscal years ended June 30, 2024 and 2023, respectively. The decrease in cash flows provided by operating activities during the fiscal year ended June 30, 2024 compared to the fiscal year ended June 30, 2023 was primarily due to lower non-cash adjustments partially offset by lower losses.

Net cash used in investing activities:

Net cash used in investing activities was $414 million for the fiscal year ended June 30, 2025, compared to net cash used of $351 million for the same period last fiscal year. Higher cash used to fund capital expenditures of $94 million year-over-year was partially offset by $27 million cash received from the sale of a business.

Net cash used in investing activities was $0.4 billion and $5.9 billion for the fiscal years ended June 30, 2024 and 2023, respectively. In fiscal 2023, $5.5 billion was used to fund the Merger. Cash used to fund capital expenditures decreased by $89 million during the fiscal year ended June 30, 2024 compared to the fiscal year ended June 30, 2023.

Net cash provided by (used in) financing activities:

Net cash used in financing activities was $452 million for the fiscal year ended June 30, 2025, compared to net cash provided by financing activities of $758 million for the same period last fiscal year. Cash outflows for the current fiscal year were primarily payments on existing debt. Financing inflows in the prior year included the $1.0 billion contribution from noncontrolling interests and proceeds from employee stock purchases, partially offset by payments on existing debt and equity issuance costs related to the contribution from noncontrolling interests.

Net cash provided by financing activities was $758 million for the year ended June 30, 2024 compared to net cash provided by financing activities of $3,554 million for the year ended June 30, 2023. Financing inflows in fiscal 2024 included the $1.0 billion contribution from noncontrolling interests and proceeds from employee stock purchases, partially offset by payments on existing debt and equity issuance costs related to the contribution from noncontrolling interests. Cash inflows for fiscal 2023 were from borrowings under the New Term Facilities, defined below, as well the net proceeds from the issuance of Coherent’s Series B-2 Convertible Preferred Stock. Financing outflows included payments to settle the Company’s existing senior credit facilities.

Senior Credit Facilities

On July 1, 2022, Coherent entered into a Credit Agreement by and among the Company, the lenders, and other parties thereto, and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent, which provides for senior secured financing of $4.0 billion, consisting of a term loan A credit facility (the “Term A Facility”), with an aggregate principal amount of $850

44

million, a term loan B credit facility (the “Term B Facility” and, together with the Term A Facility, the “Term Facilities”), with an aggregate principal amount of $2,800 million, and a revolving credit facility (the “Revolving Credit Facility” and, together with the Term Facilities, the “Senior Credit Facilities”), in an aggregate available amount of $350 million, including a letter of credit sub-facility of up to $50 million. On March 31, 2023, Coherent entered into Amendment No. 1 to the Credit Agreement, which replaced the adjusted LIBOR-based rate of interest therein with an adjusted Secured Overnight Financing Rate (“SOFR”) based rate of interest. As amended, the Term A Facility and the Revolving Credit Facility each bear interest at an adjusted SOFR rate subject to a 0.10% floor plus a range of 1.75% to 2.50%, based on the Company’s total net leverage ratio. The Term A Facility and the Revolving Credit Facility borrowings bear interest at adjusted SOFR plus 1.85% as of June 30, 2025. On April 2, 2024, Coherent entered into Amendment No. 2 to the Credit Agreement, under which the principal amount of term B loans outstanding under the Credit Agreement (the “Existing Term B Loans”) were replaced with an equal amount of new term loans (the “New Term B Loans”) having substantially similar terms as the Existing Term B Loans, except with respect to the interest rate applicable to the New Term B Loans and certain other provisions. On January 2, 2025, Coherent entered into Amendment No. 3 to the Credit Agreement, under which the principal amount of the New Term B Loans were replaced with an equal amount of new term loans (the “New Term B-2 Loans”) having substantially similar terms as the New Term B Loans, except with respect to the interest rate applicable to the New Term B-2 Loans and certain other provisions. As further amended, the New Term B-2 Loans bear interest at a SOFR rate (subject to a 0.50% floor) plus 2.00% as of June 30, 2025. The maturity of the New Term B-2 Loans and revolving credit facility remains unchanged. In relation to the Term Facilities, the Company incurred expense of $192 million for the fiscal year ended June 30, 2025, which is included in Interest expense in the Consolidated Statements of Earnings (Loss). On July 1, 2023, our interest rate cap became effective, which together with our interest rate swap (through September 30, 2024), reduced interest expense by $32 million during the fiscal year ended June 30, 2025.

During the fiscal year ended June 30, 2025, the Company made payments of $433 million for the Term Facilities, including voluntary prepayments of $400 million.

As of June 30, 2025, the Company had no borrowings outstanding under the Revolving Credit Facility.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 6% and 7% for the years ended June 30, 2025 and 2024, respectively.

Our cash position, borrowing capacity and debt obligations are as follows (in millions):

	June 30, 2025		June 30, 2024
Cash and cash equivalents	$	909	$	926
Restricted cash, current	9		174
Restricted cash, non-current	715		690
Available borrowing capacity under Revolving Credit Facility	315		346
Total debt obligations	3,687		4,100

Other Liquidity

On December 4, 2023, the Company completed two investment agreements under which Silicon Carbide LLC, a Company subsidiary, received $1.0 billion cash in exchange for 25% of the equity of that entity. Such funds have and will continue to be used primarily to fund future capital expansion in our silicon carbide business and will enable us to increase our available free cash flow to provide greater financial and operational flexibility to execute our capital allocation priorities. See Note 11. Noncontrolling Interests to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for further information.

The Company believes existing cash, cash flow from operations, and available borrowing capacity from its Senior Credit Facilities will be sufficient to fund its needs for working capital, capital expenditures, repayment of scheduled long-term borrowings and lease obligations, investments in R&D, and internal and external growth objectives at least through fiscal year 2026.

Our cash and cash equivalent balances are generated and held in numerous locations throughout the world, including amounts held outside the United States. As of June 30, 2025, we held approximately $813 million of cash, cash equivalents and restricted cash outside of the United States. Generally, cash balances held outside the United States could be repatriated to the United States.

At June 30, 2025, we had $724 million of restricted cash, which includes $720 million at our Silicon Carbide LLC that is restricted for use by only that subsidiary.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as defined by Regulation S-K of the Securities Act of 1933.

Contractual Obligations

As of June 30, 2025, in the ordinary course of business, we had total estimated purchase commitments from vendors of approximately $1,092 million. In addition, as of June 30, 2025, we had obligations under our operating leases of approximately $263 million, $58 million of which will be paid in the fiscal year 2026.

Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISKS

We are exposed to market risks arising from adverse changes in foreign currency exchange rates and interest rates. In the normal course of business, we have the option to use a variety of techniques and derivative financial instruments as part of our overall risk management strategy, which is primarily focused on our exposure in relation to the Chinese Renminbi, Euro, Swiss Franc, Japanese Yen, Singapore Dollar and Korean Won. As of September 30, 2024, after weighing the costs and benefits of hedging foreign exchange risks on our global balance sheets, we paused our balance sheet hedging program indefinitely. We continue to analyze these risks and the costs and benefits inherent in a hedging program.

Interest Rate Risk

As of June 30, 2025, our total borrowings include variable rate borrowings, which expose us to changes in interest rates. In November 2019, we entered into an interest rate swap contract, amended on March 20, 2023, to limit the exposure of our variable interest rate debt by effectively converting a portion of interest payments to fixed interest rate debt. The interest rate swap expired on September 24, 2024. On February 23, 2022, we entered into an interest rate cap (the “Cap”), amended on March 20, 2023, with an effective date of July 1, 2023. On September 1, 2024, we increased the notional amount from $500 million to $1,500 million. If we had not effectively hedged our variable rate debt, a change in the interest rate of 100 basis points on these variable rate borrowings would have resulted in additional interest expense of $30 million for the year ended June 30, 2025.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management’s Responsibility for Preparation of the Financial Statements

Management is responsible for the preparation of the Consolidated Financial Statements included in this Annual Report on Form 10-K. The Consolidated Financial Statements were prepared in accordance with the accounting principles generally accepted in the United States of America and include amounts that are based on the best estimates and judgments of management. The other financial information contained in this Annual Report on Form 10-K is consistent with the Consolidated Financial Statements.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rules 13a-159f) and 15(d)-15(f). The Company’s internal control system is designed to provide reasonable assurance concerning the reliability of the financial data used in the preparation of the Company’s Consolidated Financial Statements, as well as reasonable assurance with respect to safeguarding the Company’s assets from unauthorized use or disposition.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement presentation and other results of such systems.

Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of June 30, 2025. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Management’s evaluation included reviewing the documentation of its controls, evaluating the design effectiveness of controls and testing their operating effectiveness. Based on the evaluation, management concluded that as of June 30, 2025, the Company’s internal controls over financial reporting were effective.

Ernst & Young LLP, an independent registered public accounting firm, has issued its report on the effectiveness of our internal control over financial reporting as of June 30, 2025, which report is included herein.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Coherent Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Coherent Corp. and subsidiaries (the Company) as of June 30, 2025 and 2024, the related consolidated statements of earnings (loss), comprehensive income (loss), shareholders’ equity and mezzanine equity and cash flows for each of the three years in the period ended June 30, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at June 30, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of June 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated August 14, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Assessment - Lasers Reporting Unit
Description of the Matter	At June 30, 2025, the balance of the Company’s goodwill related to the Lasers reporting unit was $3.2 billion. As discussed in Note 1 to the consolidated financial statements, goodwill is reviewed annually for impairment, or more frequently if impairment indicators arise. The assessment of goodwill for impairment requires a comparison of the fair value of each reporting unit that has goodwill associated with its operations to its carrying amount, including goodwill. If the Company’s carrying amount of a reporting unit exceeds its fair value, an impairment loss would be measured as the excess of the carrying value over the calculated fair value. Auditing the Company’s annual goodwill impairment test for the Lasers reporting unit is complex because it involves making assumptions about the timing and amount of the forecasted future net cash flows of the reporting unit. The fair value estimate can be sensitive to significant assumptions such as revenue and the selected discount rate, which is based on a risk-adjusted weighted average cost of capital. These significant assumptions are forward looking and could be impacted by future economic conditions.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s goodwill impairment evaluation process, including controls over management’s review of the assumptions described above. Our audit procedures to test management’s impairment evaluation of the Lasers reporting unit included, among others, assessing the valuation methodology and assumptions discussed above, and the underlying data used to develop such assumptions. For example, we compared certain assumptions to current industry, market and economic trends. Where appropriate, we evaluated whether changes to the Company’s business and other factors would affect the assumptions. We also assessed the historical accuracy of management’s estimates and performed independent sensitivity analyses. We involved our valuation specialists to assist us in evaluating the methodologies and auditing the assumptions used to calculate the estimated fair value of the Lasers reporting unit.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Coherent Corp.

Opinion on Internal Control Over Financial Reporting

We have audited Coherent Corp. and subsidiaries’ internal control over financial reporting as of June 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Coherent Corp. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of June 30, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of June 30, 2025 and 2024, the related consolidated statements of earnings (loss), comprehensive income (loss), shareholders’ equity and mezzanine equity and cash flows for each of the three years in the period ended June 30, 2025, and the related notes and schedule listed in the Index at Item 15(a)(2) and our report dated August 14, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

Coherent Corp. and Subsidiaries

Notes to Consolidated Financial Statements

Note 1.        Nature of Business and Summary of Significant Accounting Policies

Nature of Business. Coherent Corp. (“Coherent,” the “Company,” “we,” “us” or “our”), a global leader in materials, networking, and lasers, is a vertically-integrated manufacturing company that develops, manufactures, and markets engineered materials, optoelectronic components and devices, and lasers for use in the industrial, communications, electronics and instrumentation markets. The Company markets its products through its direct sales force and through distributors and agents.

The Company uses certain uncommon materials and compounds to manufacture its products. Some of these materials are available from only one proven outside source. The continued high quality of these materials is critical to the stability of our manufacturing yields.

Consolidation. The Consolidated Financial Statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified for consistency with the current year presentation.

Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates are based on management’s best knowledge of current events and actions Coherent may undertake in the future, actual results may ultimately differ from the estimates.

Foreign Currency Translation. For all foreign subsidiaries whose functional currency is not the U.S. dollar, the functional currency is the local currency. Assets and liabilities of those operations are translated into U.S. dollars using period-end exchange rates while income and expenses are translated using the average exchange rates for the reporting period. Translation adjustments are recorded as Accumulated other comprehensive income (loss) within Shareholders’ equity in the accompanying Consolidated Balance Sheets.

Cash, Cash Equivalents, and Restricted Cash. We consider highly liquid investment instruments with an original maturity of three months or less to be cash equivalents. As of June 30, 2025, we had restricted cash of $724 million that is restricted for a specific purpose, with $9 million and $715 million recorded in Restricted cash, current and Restricted cash, non-current, respectively, on our Consolidated Balance Sheet.

Allowance for Expected Credit Losses. We recognize expected credit losses resulting from the inability of our customers to make required payments through an allowance account that is measured each reporting date. We estimate credit losses over the life of our trade accounts receivable using a combination of historical loss data, current credit conditions, specific customer circumstances, and reasonable and supportable forecasts of future economic conditions.

Inventories. Inventories are valued at the lower of cost or net realizable value, with cost determined on the first-in, first-out basis. Inventory costs include material, labor and manufacturing overhead. In evaluating the net realizable value of inventory, management also considers other factors, including known trends and market conditions. We generally record a reduction to the carrying value of inventory as a charge against earnings for all products on hand more than 12 to 24 months, depending on the nature of the products, that have not been sold to customers or cannot be further manufactured for sale to alternative customers. An additional charge may be recorded for product on hand that is in excess of product sold to customers over the same periods noted above.

Property, Plant and Equipment. Property, plant and equipment are carried at cost or fair value upon acquisition. Major improvements are capitalized, while maintenance and repairs are generally expensed as incurred. We review our property, plant and equipment and other long-lived assets for impairment whenever events or circumstances indicate that the carrying amounts may not be recoverable. Depreciation on property, plant and equipment and amortization on finance lease right-of-use assets for financial reporting purposes is computed primarily by the straight-line method over the estimated useful lives for building, building improvements and land improvements of 10 to 30 years and 3 to 20 years for machinery and equipment.

59

Investment Credit. The Creating Helpful Incentives to Produce Semiconductors and Science Act of 2022 (the “CHIPS Act”) was signed into law on August 9, 2022. The CHIPS Act provides for various incentives and tax credits, among other items, including the Advanced Manufacturing Investment Credit (“AMIC”), which equals 25% of qualified investments in an advanced manufacturing facility that is placed in service after December 31, 2022. The Company expects to receive refundable federal investment tax credits through the CHIPS Act in connection with ongoing expansion projects. At least a portion of our capital expenditures qualify for this credit, which benefits us by allowing us to net the credit received against our costs. The AMIC credit is accounted as a reduction to the depreciable basis of the assets used in operations. The Company has offset the cost of property, plant, and equipment by the amount of the estimated credit of $41 million for fiscal June 30, 2025. The receivable recorded is an estimate based on the Company's interpretation of the Section 48D Advanced Manufacturing Investment Credit under the CHIPS Act, which may be refunded to us in cash to the extent it exceeds our outstanding income tax liabilities.

Leases. Leases are recognized under Accounting Standards Codification 842, Leases. The Company determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating lease right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate in determining the present value of lease payments, unless the implicit rate is readily determinable. If lease terms include options to extend or terminate the lease, the ROU asset and lease liability are measured based on the reasonably certain decision. We have lease agreements with lease and non-lease components, which are accounted for as a single lease component for all classes of leased assets for which the Company is the lessee. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the Consolidated Statements of Earnings (Loss), lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. Some leasing arrangements require variable payments that are dependent upon usage or output, or may vary for other reasons, such as insurance or tax payments. Variable lease payments are recognized as incurred, and are not presented as part of the ROU asset or lease liability. See Note 12. Leases for further information.

Business Combinations. The Company accounts for business combinations by establishing the acquisition-date fair value as the measurement for all assets acquired and liabilities assumed. Certain provisions of U.S. GAAP prescribe, among other things, the determination of acquisition-date fair value of consideration paid in a business combination (including contingent consideration) and the exclusion of transaction and acquisition-related restructuring costs from acquisition accounting.

Goodwill. The excess purchase price over the fair value allocated to identifiable tangible and intangible net assets of businesses acquired is reported as goodwill in the accompanying Consolidated Balance Sheets. We test goodwill for impairment at least annually as of April 1, or when events or changes in circumstances indicate that goodwill might be impaired. The evaluation of impairment involves comparing the current fair value of our reporting units to the recorded value (including goodwill). We use a discounted cash flow (“DCF”) model and/or a market analysis to determine the fair value of our reporting units. A number of assumptions and estimates are involved in estimating the forecasted cash flows used in the DCF model, including markets and market shares, sales volume and pricing, costs to produce, working capital changes and income tax rates. Management considers historical experience and all available information at the time the fair values of the reporting units are estimated. Goodwill impairment is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.

As of April 1 of fiscal years 2025 and 2024, we completed our annual impairment tests of our reporting units using the quantitative assessment. For fiscal year 2025, the fair values of the reporting units were determined using a discounted cash flow analysis with projected financial information based on our most recently completed long-term strategic planning processes and also considered the current financial performance compared to our prior projections of the reporting units, as well as a market analysis. As of April 1, 2025 and 2024, the fair value of each of our reporting units exceeded their carrying values.

Due to the cyclical nature of our business, and the other factors described in the section on Risk Factors set forth in Item 1A of this Annual Report on Form 10-K, the profitability of our individual reporting units may periodically be affected by downturns in customer demand, operational challenges and other factors. If material adverse conditions occur that impact one or more of our reporting units, our determination of future fair value might not support the carrying amount of one or more of our reporting units, and the related goodwill would need to be impaired.

Intangibles. Intangible assets are initially recorded at their cost or fair value upon acquisition. Finite-lived intangible assets are amortized using the straight-line method over the estimated useful lives of the assets ranging from 1 to 20 years. Indefinite-lived intangible assets are not amortized but tested annually for impairment at April 1, or when events or changes in circumstances indicate that indefinite-lived intangible assets might be impaired. As of April 1 of fiscal 2025, the Company completed a quantitative impairment test of the Coherent trade name acquired in the Merger using the relief from royalty method and determined that its fair value is well in excess of its carrying value.

60

Series A Mandatory Convertible Preferred Stock. The Mandatory Convertible Preferred Stock was initially measured at fair value, less underwriting discounts and commissions and offering expenses paid by the Company. The Preferred Stock’s dividends were cumulative, at 6% per annum. All outstanding shares of Mandatory Convertible Preferred Stock were converted to 10,240,290 shares of Company Common Stock on July 3, 2023, at a conversion ratio of 4.4523, and no shares of Mandatory Convertible Preferred Stock are currently issued and outstanding. See Note 9. Equity and Redeemable Preferred Stock for further information.

Series B Convertible Preferred Stock. The Series B-1 Convertible Preferred Stock was initially measured at fair value less issuance costs, accreted to its redemption value over a ten-year period (using the effective interest method) with such accretion accounted for as deemed dividends and reductions to Net Earnings (Loss) Available to the Common Shareholders. The Series B-2 Convertible Preferred Stock was initially measured at fair value less issuance costs, accreted to its redemption value over a ten-year period (using the effective interest method) with such accretion accounted for as deemed dividends and reductions to Net Earnings (Loss) Available to the Common Shareholders. See Note 9. Equity and Redeemable Preferred Stock for further information.

Noncontrolling Interests. The Company accounts for noncontrolling interests in accordance with ASC Topic 810-10-45, which requires the Company to present noncontrolling interests as a separate component of total shareholders’ equity on the Consolidated Balance Sheets and the consolidated net earnings (loss) attributable to its noncontrolling interests be clearly identified and presented on the face of the Consolidated Statements of Earnings (Loss) and Consolidated Statements of Comprehensive Income (Loss). See Note 11. Noncontrolling Interests for further information on the noncontrolling interests in our Silicon Carbide LLC subsidiary.

Commitments and Contingencies. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. If a loss is not both probable and reasonably estimable, or if an exposure to a loss exists in excess of the amount accrued, the Company assesses whether there is at least a reasonable possibility that a loss, or additional loss, may have been incurred. If there is a reasonable possibility that a loss, or additional loss, may have been incurred, the Company discloses the estimate of the possible loss or range of loss if it is material and an estimate can be made, or discloses that such an estimate cannot be made. The determination as to whether a loss can reasonably be considered to be possible or probable is based on management's assessment, together with legal counsel, regarding the ultimate outcome of the matter. Legal costs incurred in connection with loss contingencies are expensed as incurred. Such liabilities are adjusted as further information develops or circumstances change. Our customers may discover defects in our products after the products have been fully deployed and operated under peak stress conditions. If we are unable to correct defects or other problems, we could experience, among other things, loss of customers, increased costs of product returns and warranty expenses, damage to our brand reputation, failure to attract new customers or achieve market acceptance, diversion of development and engineering resources, or legal action by our customers. We had no material loss contingency liabilities at June 30, 2025 or 2024 related to commitments and contingencies.

Supply chain financing arrangements. The Company has entered into supply chain financing arrangements with third-party financial institutions to provide its vendors with enhanced payment options while providing the Company with added working capital flexibility. The Company does not provide any guarantees under these arrangements, does not have an economic interest in its supplier's voluntary participation, does not receive an economic benefit from the financial institutions, and no assets are pledged under the arrangements. The arrangements do not change the payable terms negotiated by the Company and our vendors and does not result in a change in the classification of amounts due as accounts payable in the Consolidated Balance Sheets. Suppliers utilized the program to accelerate receipt of payment from these financial institutions for $18 million and $10 million of the Company's outstanding Accounts payable as of June 30, 2025 and 2024, respectively. Total supplier invoices paid by the financial institutions amounted to $76 million and $38 million for the years ended June 30, 2025 and 2024, respectively. The supplier invoices included under the program require payment in full to the financial institutions consistent with the Company’s normal terms and conditions as agreed upon with the vendor.

Income Taxes. Deferred income tax assets and liabilities are determined based on the differences between the Consolidated Financial Statements and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount more likely than not to be realized. The Company’s accounting policy is to apply acquired deferred tax liabilities to pre-existing deferred tax assets before evaluating the need for a valuation allowance for acquired deferred tax assets.

61

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits is adjusted for changes in facts and circumstances. For example, adjustments could result from significant amendments to existing tax law and the issuance of regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company believes that its estimates for uncertain tax positions are appropriate and sufficient to pay assessments that may result from examinations of its tax returns. The Company recognizes both accrued interest and penalties related to unrecognized tax benefits in income tax expense.

The Company uses a portfolio approach to release the income tax effects in AOCI related to interest rate instruments and pension and postretirement benefits. Under this approach, the income tax effects are released from AOCI based on the pre-tax adjustments to interest rate instruments and pension liabilities or assets recognized within other comprehensive income (loss). Any tax effects remaining in AOCI are released only when the entire portfolio of the interest rate instruments or pension and postretirement benefits is liquidated, sold or extinguished.

Revenue Recognition. Revenue is recognized under Accounting Standards Codification 606, Revenue from Contracts with Customers (ASC 606), when or as obligations under the terms of a contract with our customer have been satisfied and control has transferred to the customer.

We have elected the practical expedient to exclude all sales and use taxes from the measurement of the transaction price. In certain customer arrangements, we are contractually entitled to reimbursement for import tariffs incurred on product shipments, the increase in consideration received due to tariff surcharges would not meet the sales and use tax practical expedient. As such, revenue including the tariff surcharge, and related tariff expense, would be recorded gross in the income statement. These reimbursements are considered part of the transaction price under ASC 606 and are recognized as revenue on a gross basis. The corresponding tariff costs are recorded in cost of goods sold.

For contracts with commercial customers, which comprise the majority of our performance obligations, ownership of the goods and associated revenue are generally transferred to customers at a point in time, generally upon shipment of a product to the customer or delivery of the product to the customer and without significant judgments. The majority of contracts typically require payment within 30 to 90 days after transfer of ownership to the customer.

We periodically enter into contracts in which a customer may purchase a combination of goods and/or services, such as products with maintenance contracts or extended warranty. Maintenance contracts and extended warranties are typically sold separately from products, and represent a distinct performance obligation. Revenue related to the performance obligation for maintenance contracts and extended warranties is recognized over time as the customer simultaneously receives and consumes the benefits provided by us.

Service revenue includes repairs, tolling arrangements and installation. Repairs, tolling and installation activities are usually completed in a short period of time (normally less than one month) and therefore recorded at a point in time when the services are completed. The majority of contracts typically require payment within 30 to 90 days after performance of the service.

Non-recurring engineering arrangements are typically recognized as product revenue over time under either the time and material practical expedient, as the entity has a right to consideration from a customer, in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, or under the output and input method. The majority of contracts typically require payment within 30 to 90 days.

Our revenue recognition policy is consistently applied across our segments, product lines, services, and geographical locations. For the periods covered herein, we measure revenue based on the amount of consideration the Company expects to be entitled to in exchange for products or services, reduced by the amount of variable consideration related to products expected to be returned. We determine variable consideration, which primarily consists of product returns and distributor sales price reductions resulting from price protection agreements, by estimating the impact of such reductions based on historical analysis of such activity.

Under ASC 606, we expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses (“SG&A”). Costs for freight and shipping are generally recorded in cost of goods sold when control of the products has transferred to the customer.

We offer an assurance-type limited warranty that products will be free from defects in materials and workmanship. We establish an accrual for estimated warranty expenses at the time revenue is recognized. The warranty is typically one year, although it can be longer periods for certain products, and is typically limited to either (1) the replacement or repair of the product or (2) a credit against future purchases.

62

We believe that disaggregating revenue by end market provides the most relevant information regarding the nature, amount, timing, and uncertainty of revenues and cash flows. See Note 3. Revenue from Contracts with Customers for further information.

Research and Development. R&D expenses include salaries, contractor and consultant fees, supplies and materials, as well as costs related to other overhead such as depreciation, facilities, utilities and other departmental expenses. The costs we incur with respect to internally developed technology, including allocations of our wafer fabrication and other manufacturing facilities and resources utilized to support R&D programs, are included in R&D expenses as incurred.

Restructuring. The Company records charges associated with approved restructuring plans to reorganize operations, to remove redundant headcount and infrastructure associated with site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. Restructuring charges can include severance costs to eliminate a specific number of positions, infrastructure charges to vacate facilities and consolidate operations and contract cancellation costs. The Company records restructuring charges when they are probable and estimable. The Company evaluates restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations, and ASC 712, Compensation-Nonretirement Post-Employment Benefits (ASC 712). See Note 20. Restructuring Plans for further information.

Assets Held-for-Sale. Assets and liabilities are classified as held-for-sale when management approves and commits to a formal plan to actively market the assets for sale at a price reasonable in relation to their estimated fair value, the assets are available for immediate sale in their present condition, an active program to locate a buyer and other actions required to complete the sale have been initiated, the sale of the assets is probable and expected to be completed within one year, and it is unlikely that significant changes will be made to the plan. These conditions are usually met from the date on which a letter of intent or agreement to sell is ready for signing. Assets held-for-sale are reported at the lower of carrying amount or fair value less costs to sell. Long-lived assets classified as held-for-sale are not subject to depreciation or amortization. The held-for-sale designation and carrying value of assets held-for-sale are periodically reviewed and adjusted as facts and circumstances indicate that a change may be necessary. See Note 21. Assets Held-for-Sale for further information.

Share-Based Compensation. Share-based compensation arrangements require the recognition in net earnings (loss) of the grant date fair value of share-based compensation (for equity-classified awards). We recognize the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period, net of forfeitures. The estimated annualized forfeitures are based on our historical experience of pre-vesting cancellations. We will record additional expense in future periods if the actual forfeiture rate is lower than estimated, and will adjust expense in future periods if the actual forfeitures are higher than estimated. See Note 13. Share-Based Compensation for a description of our share-based compensation plans and the assumptions we use to calculate the fair value of share-based compensation.

Earnings per Share. Basic earnings (loss) per share is computed by dividing net earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is computed by dividing the diluted earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. If there is a net loss for the period, diluted earnings per share is the same as basic earnings per share. See Note 10. Earnings Per Share for further information.

Accumulated Other Comprehensive Income (Loss) (“AOCI”). AOCI is a measure of all changes in shareholders’ equity that result from transactions and other economic events in the period other than transactions with owners. AOCI is a component of shareholders’ equity and consists of accumulated foreign currency translation adjustments, changes in the fair value of interest rate derivative instruments, and pension adjustments.

Fair Value Measurements. We apply fair value accounting for all financial assets and liabilities that are required to be recognized or disclosed at fair value in the Consolidated Financial Statements. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, we consider the principal or most advantageous market in which we would transact, and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.

Note 2.        Recently Issued and Adopted Financial Accounting Standards

Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted the standard during fiscal 2025. See Note 14. Segment and Geographic Reporting for further information.

Income Taxes (Topic 740): Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-09 on its consolidated financial statements and related disclosures.

Income Statement Reporting: Disaggregation of Income Statement Expenses

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.” This ASU requires disclosure about specific types of expenses included in expense captions including purchases of inventory, employee compensation, depreciation, amortization, and depletion. This ASU is effective for our annual disclosures starting in fiscal year 2028 and interim periods starting in fiscal year 2029. Early adoption is permitted. A public entity should apply the amendments in this ASU on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Senior Credit Facilities

On July 1, 2022 (the “Closing Date”), Coherent entered into a Credit Agreement (the “Credit Agreement”) by and among the Company, as borrower (in such capacity, the “Borrower”), the lenders, and other parties thereto, and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent, which provides for senior secured financing of $4.0 billion, consisting of a term loan A credit facility (the “Term A Facility”) maturing July 1, 2027, with an aggregate principal amount of $850 million, a term loan B credit facility (the “Term B Facility” and, together with the Term A Facility, the “Term Facilities”) maturing July 1, 2029, with an aggregate principal amount of $2,800 million, and a revolving credit facility (the “Revolving Credit Facility” and together with the Term Facilities, the “Senior Credit Facilities”) maturing July 1, 2027, in an aggregate available amount of $350 million, including a letter of credit sub-facility of up to $50 million. On March 31, 2023, Coherent entered into Amendment No. 1 to the Credit Agreement, which replaced the adjusted LIBOR-based rate of interest therein with an adjusted SOFR-based rate of interest. As amended, the Term A Facility and the Revolving Credit Facility each bear interest at an adjusted SOFR rate subject to a 0.10% floor plus a range of 1.75% to 2.50%, based on the Company’s total net leverage ratio. The Term A Facility and the Revolving Credit Facility bear interest at adjusted SOFR plus 1.85% as of June 30, 2025. On April 2, 2024, Coherent entered into Amendment No. 2 to the Credit Agreement, under which the principal amount of term B loans outstanding under the Credit Agreement (the “Existing Term B Loans”) were replaced with an equal amount of new term loans (the “New Term B Loans”) having substantially similar terms as the Existing Term B Loans, except with respect to the interest rate applicable to the New Term B Loans and certain other provisions. Debt extinguishment costs related to the replacement of the Existing Term B Loans of $2 million were expensed in Other expense (income), net in the Consolidated Statement of Earnings (Loss) during the year ended June 30, 2024. On January 2, 2025, Coherent entered into Amendment No. 3 to the Credit Agreement, under which the principal amount of New Term B Loans outstanding under the Credit Agreement were replaced with an equal amount of new term loans (the “New Term B-2 Loans”) having substantially similar terms as the New Term B Loans, except with respect to the interest rate applicable to the New Term B-2 Loans and certain other provisions. As

67

further amended, the New Term B-2 Loans bear interest at a SOFR rate (subject to a 0.50% floor) plus 2.00% as of June 30, 2025. The maturity of the New Term B-2 Loans and Revolving Credit Facility remains unchanged.

In relation to the Term Facilities, the Company incurred interest expense, including amortization of debt issuance costs and the benefit of the interest rate cap and swap, of $192 million and $237 million in the years ended June 30, 2025 and June 30, 2024, respectively, which is included in Interest expense in the Consolidated Statements of Earnings (Loss). On July 1, 2023, our interest rate cap became effective, which together with our interest rate swap (through September 30, 2024), reduced interest expense by $32 million and $45 million in the years ended June 30, 2025 and June 30, 2024, respectively. Amortization of debt issuance costs related to the Term Facilities for the year ended June 30, 2025 and June 30, 2024 totaled $17 million and $15 million, respectively, and are included in Interest expense in the Consolidated Statements of Earnings (Loss). Debt issuance costs are presented as a reduction to debt within the Long-term debt caption in the Consolidated Balance Sheets.

On the Closing Date, the Borrower and certain of its direct and indirect subsidiaries, provided a guaranty of all obligations of the Borrower and the other loan parties under the Credit Agreement and the other loan documents, secured cash management agreements and secured hedge agreements with the lenders and/or their affiliates (subject to certain exceptions). The Borrower and the other guarantors have also granted a security interest in substantially of their assets to secure such obligations.

As of June 30, 2025, the Company was in compliance with all covenants under the Term Facilities.

Debt Assumed through Acquisition

We assumed the remaining balances of three term loans with the closing of the Merger, two of which were repaid prior to June 30, 2024. The aggregate principal amount outstanding is $18 million as of June 30, 2025 and is for a Facility construction loan in Germany due in 2030 that bears interest at 1.55% per annum. Payments are made quarterly.

5.000% Senior Notes due 2029

On December 10, 2021, the Company issued $990 million aggregate principal amount of Senior Notes pursuant to the indenture, dated as of December 10, 2021 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Senior Notes are guaranteed by each of the Company’s domestic subsidiaries that guarantee its obligations under the Senior Credit Facilities. Interest on the Senior Notes is payable on December 15 and June 15 of each year, commencing on June 15, 2022, at a rate of 5.000% per annum. The Senior Notes will mature on December 15, 2029.

On or after December 15, 2024, the Company may redeem the Senior Notes, in whole at any time or in part from time to time, at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to December 15, 2024, the Company had the ability to (but did not) redeem the Senior Notes, at its option, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Senior Notes redeemed, plus a “make-whole” premium set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Notwithstanding the foregoing, at any time and from time to time prior to December 15, 2024, the Company had the ability to (but did not) redeem up to 40% of the aggregate principal amount of the Senior Notes using the proceeds of certain equity offerings as set forth in the Indenture, at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.

In relation to the Senior Notes, we incurred interest expense of $50 million for both the years ended June 30, 2025 and June 30, 2024, which is included in Interest expense in the Consolidated Statements of Earnings (Loss).

The Indenture contains customary covenants and events of default, including default relating to among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Senior Notes and certain provisions related to bankruptcy events. As of June 30, 2025, the Company was in compliance with all covenants under the Indenture.

Aggregate Availability

The Company had aggregate availability of $315 million under its Revolving Credit Facility as of June 30, 2025.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 6% and 7% for the years ended June 30, 2025 and 2024, respectively.

On July 4, 2025, the U.S. government enacted The One Big Beautiful Bill Act of 2025 which includes, among other provisions, changes to the U.S. corporate income tax system including the allowance of immediate expensing of qualifying research and development expenses and permanent extensions of certain provisions within the Tax Cuts and Jobs Act. Certain provisions are effective for the Company beginning fiscal 2026. The Company is evaluating the future impact of these tax law changes on its financial statements.

The Company is partially permanently reinvested and will repatriate earnings for all non-U.S. subsidiaries with cash in excess of working capital needs. Such distributions could potentially be subject to U.S. state tax in certain states and foreign withholding taxes. Foreign currency gains (losses) related to the translation of previously taxed earnings from functional currency to U.S. dollars could also be subject to U.S. tax when distributed. The Company has estimated the associated withholding tax to be $63 million.

Additionally, the Company made a final accounting policy election to treat taxes due from future inclusions in U.S. taxable income related to global intangible low tax income (“GILTI”) as a current period expense when incurred.

During the fiscal years ended June 30, 2025, 2024, and 2023, cash paid by the Company for income taxes was $167 million, $97 million, and $90 million, respectively.

Our foreign subsidiaries in various tax jurisdictions operate under tax holiday arrangements. The impact of the tax holidays on our effective rate is a reduction in the rate of 11.6%, 5.6% and 2.3% for the fiscal years ended June 30, 2025, 2024 and 2023, respectively, and the impact of the tax holidays on diluted earnings per share is $0.06, $0.05, and $0.05 for the fiscal years ended June 30, 2025, 2024, and 2023, respectively. The tax holiday related to Coherent Malaysia Sdn. Bhd will end during the fiscal year ended June 30, 2026 for certain business lines, the tax holiday related to certain II-VI Laser Enterprise Philippines, Inc.’s business lines will end during the fiscal year ended June 30, 2026, the tax holiday related to Silicon Carbide Vietnam Limited Liability Company will end during the fiscal year ended June 30, 2026, the tax holiday related to certain Coherent Vietnam (Dong Nai) Company Limited business lines will end during the fiscal year ended June 30, 2026, and the tax holiday related to certain Coherent Singapore PTE Ltd business lines will end during the fiscal year ended June 30, 2027.

The Company has the following gross operating loss carryforwards and tax credit carryforwards as of June 30, 2025 ($000):

Type	Amount		Expiration Date
Tax credit carryforwards:
Federal research and development credits	$	121,286	June 2032-June 2045
Foreign tax credits	12,964		June 2030-June 2035
State tax credits	15,976		June 2026-June 2040
State tax credits (indefinite)	79,179		Indefinite
Operating loss carryforwards:
Loss carryforwards - federal	$	31,278	June 2026-June 2036
Loss carryforwards - federal (indefinite)	1,754		Indefinite
Loss carryforwards - state	330,313		June 2026-June 2045
Loss carryforwards - state (indefinite)	42,674		Indefinite
Loss carryforwards - foreign	85,218		June 2026-June 2033
Loss carryforwards - foreign (indefinite)	48,711		Indefinite

The Company has recorded a valuation allowance against the majority of the foreign and state loss and credit carryforwards, certain U.S. credit carryforwards and the majority of state credit carryforwards. The Company’s U.S. federal loss carryforwards, federal research and development credit carryforwards, foreign tax credits, and certain state tax credits resulting from the Company’s acquisitions are subject to various annual limitations under Section 382 of the U.S. Internal Revenue Code.

Changes in the liability for unrecognized tax benefits for the fiscal years ended June 30, 2025, 2024 and 2023 were as follows ($000):

Year Ended June 30,	2025		2024		2023
Beginning balance	$	116,697	$	115,180	$	37,411
Increases in current year tax positions	9,660		5,168		110
Acquired business	—		—		86,077
Settlements	—		(2,970)		—
Expiration of statute of limitations	(2,349)		(681)		(8,418)
Ending balance	$	124,008	$	116,697	$	115,180

The Company classifies all estimated and actual interest and penalties as income tax expense. During fiscal years 2025, 2024 and 2023, there was $2.0 million, $2.3 million and $0.3 million of interest and penalties within income tax expense, respectively. The Company had $9 million, $7 million and $6 million of interest and penalties accrued at June 30, 2025, 2024 and 2023, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. The majority of the liability can be offset by credit carryforwards and would not impact cash taxes. Including tax positions for which the Company determined that the tax position would not meet the more likely than not recognition threshold upon examination by the tax authorities based upon the technical merits of the position, the total estimated unrecognized tax benefit that, if recognized, would affect our effective tax rate, was approximately $20 million, $19 million and $92 million at June 30, 2025, 2024 and 2023, respectively. For the years ended June 30, 2025 and June 30, 2024, due to the U.S. valuation allowance, a large portion of our unrecognized tax benefit will no longer impact the tax rate if recognized. The Company expects a decrease of $67 million of unrecognized tax benefits during the next 12 months due to the expiration of statutes of limitation.

Fiscal years 2018 and 2022 to 2025 remain open to examination by the Internal Revenue Service, fiscal years 2021 to 2025 remain open to examination by certain state jurisdictions, and fiscal years 2012 to 2025 remain open to examination by certain foreign taxing jurisdictions. The Company is currently under examination for certain subsidiary companies in Vietnam for the years ended June 30, 2017 through September 30, 2021; Malaysia for the years ended June 30, 2021 through June 30, 2023; Singapore for the year ended June 30, 2023; United Kingdom for the year ended June 30, 2023; and Germany for the years ended June 30, 2012 through June 30, 2021. The Company believes its income tax reserves for these tax matters are adequate.

Note 9.         Equity and Redeemable Preferred Stock

As of June 30, 2025, the Company’s amended and restated articles of incorporation authorize our board of directors, without the approval of our shareholders, to issue 5 million shares of our preferred stock. As of June 30, 2025, 2.3 million shares of mandatory preferred convertible shares have been authorized, none are outstanding; 75,000 shares of Series B-1 convertible preferred stock, no par value, have been issued and are outstanding; and 140,000 shares of Series B-2 convertible preferred stock, no par value, have been issued and are outstanding.

Mandatory Convertible Preferred Stock

In July 2020, we issued 2.3 million shares of Mandatory Convertible Preferred Stock.

All outstanding shares of Mandatory Convertible Preferred Stock were converted to 10,240,290 shares of Company Common Stock on July 3, 2023, at a conversion ratio of 4.4523, and no shares of Mandatory Convertible Preferred Stock are currently issued and outstanding.

Series B Convertible Preferred Stock

In March 2021, the Company issued 75,000 shares of Series B-1 Convertible Preferred Stock, no par value per share (“Series B-1 Preferred Stock”), for $10,000 per share, resulting in an aggregate purchase price of $750 million. On July 1, 2022, the Company issued 140,000 shares of Series B-2 Convertible Preferred Stock, no par value per share (“Series B-2 Preferred Stock” and, together with the Series B-1 Preferred Stock, the “Series B Preferred Stock”), for $10,000 per share and an aggregate purchase price of $1.4 billion.

The shares of Series B Preferred Stock are convertible into shares of Coherent Common Stock as follows:

•at the election of the holder, each share of Series B Preferred Stock may be converted into shares of Coherent Common Stock at a conversion price of $85 per share (as it may be adjusted from time to time, the “Conversion Price”); and

•at the election of the Company at the then-applicable Conversion Price if the volume-weighted average price of Coherent Common Stock exceeds 150% of the then-applicable Conversion Price for 20 trading days out of any 30 consecutive trading days.

72

The issued shares of Series B Preferred Stock currently have voting rights, voting as one class with the Coherent Common Stock, on an as-converted basis, subject to limited exceptions.

On or at any time after March 31, 2031 and July 1, 2032 for the Series B-1 and B-2 Preferred Stock, respectively:

•each holder has the right to require the Company to redeem all of their Series B Preferred Stock, for cash, at a redemption price per share equal to the sum of the Stated Value (as defined in the Statement with Respect to Shares establishing the Series B Preferred Stock) for such shares plus an amount equal to all accrued or declared and unpaid dividends on such shares that had not previously been added to the Stated Value (such price the “Redemption Price,” and such right the “Put Right”), and

•the Company has the right to redeem, in whole or in part, on a pro rata basis from all holders based on the aggregate number of shares of Series B Preferred Stock outstanding, for cash, at the Redemption Price.

In connection with any Fundamental Change (as defined in the Statement with Respect to Shares establishing the Series B Preferred Stock), and subject to the procedures set forth in the Statement with Respect to Shares establishing the Series B Preferred Stock, the Company must, or will cause the survivor of a Fundamental Change to, make an offer to repurchase, at the option and election of the holder thereof, each share of Series B-1 Preferred Stock then outstanding at a purchase price per share in cash equal to (i) the Stated Value for such shares plus an amount equal to all accrued or declared and unpaid dividends on such shares that had not previously been added to the Stated Value as of the date of repurchase plus (ii) if prior to March 31, 2026 and July 1, 2027, for the Series B-1 and B-2 Preferred Stock, respectively, the aggregate amount of all dividends that would have been paid (subject to certain exceptions), from the date of repurchase through March 31, 2026 and July 1, 2027, for the Series B-1 and B-2 Preferred Stock, respectively.

If the Company defaults on a payment obligation with respect to the Series B Preferred Stock, and such default is not cured within 30 days, the dividend rate will increase to 8% per annum and will be increased by an additional 2% per annum each quarter the Company remains in default, not to exceed 14% per annum.

The Series B Preferred Stock is redeemable for cash outside of the control of the Company upon the exercise of the Put Right, and upon a Fundamental Change, and is therefore classified as mezzanine equity.

The Series B Preferred Stock is initially measured at fair value less issuance costs, accreted to its redemption value over a 10-year period (using the effective interest method) with such accretion accounted for as deemed dividends and reductions to Net Earnings (Loss) available to Common Shareholders.

Preferred stock dividends are presented as a reduction to Retained earnings on the Consolidated Balance Sheets.

The following table presents dividends per share and dividends recognized for the years ended June 30, 2025, and June 30, 2024:

	Year Ended June 30, 2025		Year Ended June 30, 2024
Dividends per share	$	604	$	574
Dividends ($000)	123,688		117,894
Deemed dividends ($000)	6,238		5,463

Note 10.        Earnings Per Share

Basic earnings (loss) per common share is computed by dividing net earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock outstanding during the period.

Diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to the common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. The shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock are calculated under the If-Converted method. For the years ended June 30, 2025, June 30, 2024 and June 30, 2023, as the Company was in a net loss position, there were no dilutive shares. For the years ended June 30, 2025, June 30, 2024 and June 30, 2023, diluted earnings (loss) per share excluded the potentially dilutive effect of the performance and restricted shares, as well as the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock as their effects were anti-dilutive.

Note 11.     Noncontrolling Interests

On December 4, 2023, Silicon Carbide LLC (“Silicon Carbide”), one of the Company’s subsidiaries, completed (i) the sale of 16,666,667 Class A Common Units to Denso Corporation (“Denso”) for $500,000,000 pursuant to an Investment Agreement, dated as of October 10, 2023, by and between Silicon Carbide and Denso and (ii) the sale of 16,666,667 Class A Common Units to Mitsubishi Electric Corporation (“MELCO”) for $500,000,000 pursuant to an Investment Agreement, dated as of October 10, 2023, by and between Silicon Carbide and MELCO (collectively, the “Equity Investments”).

As a consequence of the Equity Investments, the Company’s ownership interest in the Class A Common Units of Silicon Carbide LLC was reduced to approximately 75%. Denso and MELCO each, individually, own approximately 12.5% of the Class A Common Units of Silicon Carbide LLC.

The Equity Investments in Silicon Carbide enables Coherent to increase its available free cash flow to provide greater financial and operational flexibility to execute its capital allocation priorities, as the aggregate $1 billion investment, net of transaction costs, is being and will continue to be used to fund future capital expansion of Silicon Carbide.

The following table presents the activity in noncontrolling interests in Silicon Carbide ($000):

Note 12.        Leases

The determination of whether an arrangement is, or contains, a lease is performed at the inception of the arrangement. Classification and initial measurement of the right-of-use asset and lease liability are determined at the lease commencement

74

date. The Company elected the short-term lease measurement and recognition exemption; therefore, leases with an initial term of 12 months or less are not recorded on the balance sheet.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance lease assets are recorded in Property, plant and equipment, net, and finance lease liabilities within Other accrued liabilities and Other liabilities on our Consolidated Balance Sheets. Finance lease assets are amortized in operating expenses on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term, with the interest component for lease liabilities included in interest expense and recognized using the effective interest method over the lease term.

Operating leases are recorded in Other assets and Operating lease liabilities, current and non-current on our Consolidated Balance Sheets. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

Our lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our lease assets and corresponding liabilities. Our lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

Our lease assets also include any lease payments made, and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

The following table presents lease costs, which include leases for arrangements with an initial term of more than 12 months, lease term, and discount rates ($000):

Note 13.        Share-Based Compensation

The Company grants equity awards pursuant to the Coherent Corp. Omnibus Incentive Plan (as amended and restated, the “Plan”). The Plan was originally approved by the Company's shareholders at the Annual Meeting in November 2018, and was subsequently amended, restated and approved by the Company’s shareholders at the Annual Meetings held in November 2020, November 2023 and November 2024. The Plan provides for the grant of stock options, stock appreciation rights, restricted shares, restricted share units, deferred shares, performance shares and performance units to employees (including officers), consultants and directors of the Company. The maximum number of shares of Coherent Common Stock authorized for issuance under the Plan is limited to 13,450,000 shares of Coherent Common Stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. Certain awards under the Plan have certain vesting provisions predicated upon the death, retirement or disability of the grantee.

As of June 30, 2025, there were approximately 8 million shares available to be issued under the Plan, including forfeited shares from predecessor plans.

On June 3, 2024, the Board of Directors granted 147,214 restricted stock units vesting over three years from date of grant and 694,007 performance stock units vesting over the approximate three-year period ending June 30, 2027, to the new CEO. The grants were non-Plan “employment inducement awards” as contemplated by the New York Stock Exchange Listing Rule 303A.08 and therefore were not made pursuant to the Plan.

On October 11, 2024, the Board of Directors granted 15,902 and 63,154 restricted stock units vesting over three years and two years, respectively, from date of grant and 118,853 performance stock units vesting over the approximate three-year period ending June 30, 2027, to the new CFO. The grants were “employment inducement awards” as contemplated by the New York Stock Exchange Listing Rule 303A.08 and therefore were not made pursuant to the Plan.

The Company has an Employee Stock Purchase Plan whereby eligible employees may authorize payroll deductions (subject to certain limitations) of up to 15% (or such lessor amount as may be determined by the plan administrator) of their wages and base salary to purchase shares at an amount which will not be less than 85% of lower of (i) the fair market value of the common stock on the first trading day of the offering period and (ii) the fair market value of the common stock on the last trading day of the approximately six-month offering period.

We record share-based compensation expense for these awards, which requires the recognition of the grant-date fair value of share-based compensation in net earnings. We recognize the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period. We account for cash-based stock appreciation rights, cash-based restricted share units and cash-based performance share units as liability awards.

76

Share-based compensation expense for the fiscal years ended June 30, 2025, 2024 and 2023 is as follows ($000):

Year Ended June 30,	2025		2024		2023
Stock Options and Cash-Based Stock Appreciation Rights	$	334	$	1,149	$	2,602
Restricted Share Awards and Cash-Based Restricted Share Unit Awards	93,223		92,634		124,212
Performance Share Awards and Cash-Based Performance Share Unit Awards	57,767		21,912		14,998
Employee Stock Purchase Plan	9,648		11,200		7,819
	$	160,972	$	126,895	$	149,631

Stock Options and Cash-Based Stock Appreciation Rights

We utilize the Black-Scholes valuation model for estimating the fair value of stock options and cash-based stock appreciation rights. During the fiscal years ended June 30, 2025, June 30, 2024 and June 30, 2023, no stock options were issued.

Stock option and cash-based stock appreciation rights activity during the fiscal year ended June 30, 2025 was as follows:

	Stock Options			Cash-Based Stock Appreciation Rights

Exercisable - June 30, 2025	897,096	$	35.43	25,133	$	36.93

As of June 30, 2025, 2024 and 2023, the aggregate intrinsic value of stock options and cash-based stock appreciation rights outstanding and exercisable was $50 million, $61 million and $44 million, respectively. Aggregate intrinsic value represents the total pretax intrinsic value (the difference between our closing stock price on the last trading day of the year ended June 30, and the option’s exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on June 30, 2025. This amount varies based on the fair market value of the Company’s stock. The total intrinsic value of stock options and cash-based stock appreciation rights exercised during the fiscal years ended June 30, 2025, 2024, and 2023 was $36 million, $25 million, and $5 million, respectively. As of June 30, 2025, there was no unrecognized compensation cost related to non-vested stock options and cash-based stock appreciation rights.

Outstanding and exercisable stock options at June 30, 2025 were as follows:

Restricted Share Awards, Restricted Share Units, and Cash-Based Restricted Share Units

Restricted share awards, restricted share units, and cash-based restricted share units compensation expense was calculated based on the number of shares or units expected to be earned by the grantee multiplied by the stock price at the date of grant (for restricted share awards and restricted share units) or the stock price at the period end date (for cash-based restricted share units), and is being recognized over the vesting period. Generally, the restricted share awards, restricted share units, and cash-based restricted share units have a three-year tranche vesting provision. There were no restricted share awards issued in the fiscal years ending June 30, 2025 and June 30, 2024, and all previous restricted share awards have been amortized in full.

77

Restricted share unit and cash-based restricted share unit activity during the fiscal year ended June 30, 2025, was as follows:

	Restricted Share Units			Cash-Based Restricted Share Units
	Number of Units	Weighted Average Grant Date  Fair Value		Number of Units	Weighted Average Grant Date  Fair Value
Nonvested - June 30, 2024	4,067,885	$	45.84	8,984	$	43.00
Granted	1,554,412	$	81.70	5,031	$	77.59

Nonvested - June 30, 2025	3,185,952	$	61.13	9,699	$	59.49

As of June 30, 2025, total unrecognized compensation cost related to non-vested, restricted share units and cash-based restricted share units was $119 million. This cost is expected to be recognized over a weighted-average period of approximately 2 years. The restricted share unit compensation expense was calculated based on the number of shares expected to be earned, multiplied by the stock price at the date of grant, and is being recognized over the vesting period. The cash-based restricted share unit compensation expense was calculated based on the number of units expected to be earned, multiplied by the stock price at the period-end date, and is being recognized over the vesting period. The total fair value of the restricted share awards, restricted share units, and cash-based restricted share units granted during the years ended June 30, 2025, 2024 and 2023, was $127 million, $110 million and $102 million, respectively. The total fair value of restricted share awards, restricted share units and cash-based restricted share units vested was $185 million, $74 million and $131 million during fiscal years 2025, 2024 and 2023, respectively.

Performance Share Units

The Compensation Committee of the Board of Directors of the Company has granted certain executive officers and employees performance share units under the Plan. As of June 30, 2025, we had outstanding grants covering performance periods ranging from 12 to 36 months. These grants are intended to provide continuing emphasis on specified financial performance goals that the Company considers important contributors to the creation of long-term shareholder value. These grants are payable only if the Company achieves specified levels of financial performance during the performance periods.

For our relative Total Shareholder Return (“TSR”) performance-based units, which are based on market performance of our stock as compared to the S&P Composite 1500 – Electronic Equipment, Instruments & Components Index, the compensation cost is recognized over the performance period on a straight-line basis, because the grants vest only at the end of the measurement period, and the probability of actual shares expected to be earned is considered in the grant date valuation. As a result, the expense is not adjusted to reflect the actual shares earned. We estimate the fair value of the TSR performance-based units using the Monte-Carlo simulation model.

The performance share unit compensation expense was calculated based on the number of shares expected to be earned, multiplied by the stock price at the date of grant, and is being recognized over the vesting period.

Performance share unit activity relating to the Plan during the year ended June 30, 2025, was as follows:

	Performance Share Units
	Number of Units	Weighted Average Grant Date Fair Value
Nonvested - June 30, 2024	1,702,741	$	73.86
Granted	644,174	$	136.38
Vested	(131,239)	$	81.32
Forfeited	(77,542)	$	77.91
Nonvested - June 30, 2025	2,138,134	$	92.11

As of June 30, 2025, total unrecognized compensation cost related to non-vested performance share units was $125 million. This cost is expected to be recognized over a weighted-average period of approximately 1.70 years. The total fair value of the performance share units granted during the fiscal years ended June 30, 2025, 2024 and 2023 was $88 million, $113 million and $27 million, respectively. The total fair value of performance share units and cash-based performance share units vested during the fiscal years ended June 30, 2025, 2024 and 2023 was $17 million, $14 million and $24 million, respectively.

Note 14.        Segment and Geographic Reporting

Our Chief Executive Officer has been identified as the chief operating decision maker (“CODM”) as he utilizes financial information to make decisions about allocating resources and assessing performance for the entire Company, which is used in the decision-making process to assess performance. We determine our reportable business segments based on the way the CODM organizes business segments within the Company for making operating decisions and assessing performance. Effective July 1, 2022, we report our financial results in the following three segments: (i) Networking, (ii) Materials, and (iii) Lasers.

The Networking segment has locations in the United States, Australia, China, Germany, Malaysia, South Korea, Thailand, the Philippines, the United Kingdom, and Vietnam. This segment address all of Coherent’s four end markets, namely: communications, industrial, electronics, and instrumentation, with a concentration in the communications market. This segment leverages Coherent’s compound semiconductor technology platforms and deep knowledge of end-user applications for our key end markets to deliver differentiated components, modules and subsystems.

The Materials segment has locations in the United States, China, Germany, Italy, Japan, Singapore, South Korea, Sweden, Switzerland, Taiwan, the Philippines, the United Kingdom, and Vietnam. This segment address all of Coherent’s four end markets, namely: communications, industrial, electronics, and instrumentation, with concentrations in the industrial and electronics markets. The Materials segment is a market leader in engineered materials and optoelectronic devices, such as those based on ZnSe, ZnS, GaAs, InP, GaSb, and SiC.

The Lasers segment has locations in the United States, Finland, Germany, Malaysia, Singapore, South Korea, Spain, Sweden, Switzerland, and the United Kingdom. The Lasers segment’s lasers and optics products serve industrial customers in both semiconductor and display capital equipment, precision manufacturing, and instrumentation customers in life sciences and scientific instrumentation.

During the first quarter of fiscal 2025 as a result of a new CEO joining the Company in the fourth quarter of fiscal 2024, our CODM implemented changes in the measure he uses to allocate resources and assess performance. Our CODM now evaluates each segment’s performance and allocates resources based on segment revenue and segment profit, instead of operating income, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, and certain other charges. Additionally, effective in fiscal 2025, we no longer allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. The segments are managed separately due to the market, production requirements and facilities unique to each segment. The Company derives its segment results directly from the manner in which results are reported in its management reporting system and the CODM uses segment profit to drive decisions in the forecasting process when making decisions about allocation capital and other resources to the segments. The accounting policies are consistent across each segment. Effective in fiscal 2025, we no longer allocate corporate assets to the segments.

Comparative prior period segment information has been recast to conform to the new segment profitability measure. The change in our operating segment measure had no impact on our previously reported consolidated results of operations, financial condition, or cash flows.

The following tables set forth the details of revenues and segment profit and reconciles segment profit to consolidated earnings (loss) before income taxes for the periods presented ($000):

Change in Reportable Segments in Fiscal 2026

Effective July 1, 2025 for our fiscal year 2026, the Company realigned its organizational structure into two reporting segments: (i) Datacenter and Communications, and (ii) Industrial. The Company will report financial information for these new reporting segments in fiscal 2026. This change in reporting is to occur beginning with periods commencing July 1, 2025.

Note 15.        Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. We estimate fair value of our financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

•Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

•Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

We had entered into an interest rate swap with a notional amount of $1,075 million to limit the exposure to our variable interest rate debt by effectively converting it to a fixed interest rate. Through February 28, 2023, we received payments based on the one-month LIBOR and made payments based on a fixed rate of 1.52%. We received payments with a floor of 0.00%. The initial notional amount of the interest rate swap decreased to $825 million in June 2022, and remained at that amount through its expiration on September 24, 2024. On March 20, 2023, we amended our $825 million interest rate swap (“Amended Swap”), effective as of February 28, 2023, to replace the current reference rate (LIBOR) with SOFR, to be consistent with Amendment no. 1 to the Credit Agreement. See Note 7. Debt for further information. Under the Amended Swap, we received payments based on the one-month SOFR and made payments based on a fixed rate of 1.42%. Through its expiration on September 24, 2024, we received payments with a floor of 0.10%. We designated this instrument as a cash flow hedge, and deemed the hedge relationship effective at inception of the contract and the amended contract. The interest rate swap expired on September 30,

83

2024. The fair value of the interest rate swap of $8 million is recognized in the Consolidated Balance Sheet within Prepaid and other current assets and Other assets as of June 30, 2024.

On February 23, 2022, we entered into an interest rate cap (“the Cap”) with an effective date of July 1, 2023. On March 20, 2023, we amended the Cap to replace the current reference rate (LIBOR) with SOFR, to be consistent with Amendment No. 1 to the Credit Agreement. See Note 7. Debt for further information. The Cap manages our exposure to interest rate movements on a portion of our floating rate debt. The Cap provides us with the right to receive payment if one-month SOFR exceeds 1.92%. Beginning in July 2023, we began to pay a fixed monthly premium based on an annual rate of 0.853% for the Cap. The Cap will carry a notional amount ranging from $500 million to $1,500 million. On September 1, 2024, we increased the notional amount from $500 million to $1,500 million. The fair value of the interest rate cap of $17 million and $50 million is recognized in the Consolidated Balance Sheets within prepaid and other current and other assets as of June 30, 2025 and June 30, 2024, respectively.

The Cap, as amended, is designed to mirror the terms of the Company’s Credit Agreement as amended on March 31, 2023. We designated the Cap as a cash flow hedge of the variability of the SOFR based interest payments on the Term Facilities. Every period over the life of the hedging relationship, the entire change in fair value related to the hedging instrument will first be recorded within AOCI. Amounts accumulated in AOCI will be reclassified into interest expense in the same period or periods in which interest expense is recognized on the Credit Agreement, or its direct replacement. The fair value of the Cap is determined using widely accepted valuation techniques and reflects the contractual terms of the Cap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves. The fair value analysis also considers a credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The Cap is classified as a Level 2 item within the fair value hierarchy.

We estimated the fair value of the Senior Notes, Term A Facility and Term B Facility (“Debt Facilities”) based on quoted market prices as of the last trading day prior to June 30, 2025; however, the Debt Facilities have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the Debt Facilities could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 2. The carrying values of the Debt Facilities are net of unamortized discount and issuance costs. See Note 7. Debt for further information on the Company’s debt facilities.

The fair value and carrying value of the Debt Facilities were as follows ($000):

	June 30, 2025				June 30, 2024
	Fair Value		Carrying Value		Fair Value		Carrying Value
Senior Notes	$	973,190	$	985,034	$	938,193	$	984,061
Term A Facility	632,960		616,234		777,564		762,039
Term B Facility	2,108,938		2,065,880		2,390,497		2,334,701

Our borrowings, including our lease obligations and the Debt Facilities, are considered Level 2 among the fair value hierarchy.

Cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those instruments.

At June 30, 2025, total restricted cash of $724 million includes $720 million of cash in Silicon Carbide LLC that is restricted for use only by that subsidiary and $4 million of cash restricted for other purposes in other entities. At June 30, 2024, total restricted cash of $864 million included $858 million of cash in Silicon Carbide LLC that is restricted for use only by that subsidiary and $5 million of cash restricted for other purposes in other entities. The restricted cash is invested in money market accounts and time deposits, with maturities of one year or less, that are held-to-maturity, are considered Level 1 among the fair value hierarchy and approximate fair value. Restricted cash that is expected to be spent and released from restriction after 12 months is classified as non-current on the Consolidated Balance Sheets.

We, from time to time, purchase foreign currency forward exchange contracts, that permit us to sell specified amounts of these foreign currencies for pre-established U.S. dollar amounts at specified dates that represent assets or liabilities on the balance sheets of certain subsidiaries. These contracts are entered into for the purposes of limiting translational exposure to changes in currency exchange rates and which otherwise would expose our earnings, on the revaluation of our aggregate net assets or liabilities in respective currencies, to foreign currency risk. At June 30, 2025, we had no foreign currency forward contracts. The fair values of these instruments, when outstanding, are measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. Realized gains related to these contracts for the year ended June 30, 2025 were $16 million and for June 30, 2024 and June 30, 2023 were losses of $15 million and gains of $0.2 million, respectively, and were included in Other expense (income), net in the Consolidated Statements of Earnings (Loss).

Our non-financial assets, such as goodwill, intangible assets, and property, plant and equipment, are assessed for impairment when an event or circumstance indicates that a decline in value may have occurred. See Note 1. Nature of Business and Summary of Significant Accounting Policies for further information.

Note 16.        Employee Benefit Plans

Eligible employees of the Company participate in an employee retirement plan. Under the Coherent Corp 401(k) Profit Sharing Plan (“Plan”), we match employee contributions to the plan equal to an amount of 50% of employee contributions up to a maximum of 8% of the employee’s individual earnings subject to IRS limitations. Employees become eligible for participation and Company matching contributions on their first day of employment. The Company’s matching contributions (net of forfeitures) during fiscal 2025, 2024 and 2023 were $15 million, $18 million, and $11 million, respectively. In addition, the Plan has a profit sharing retirement plan contribution for eligible U.S. employees of the Company. These contributions are made at the discretion of the Company’s Board of Directors and were $1 million for the year ended June 30, 2025 and $2 million in each of 2024 and 2023.

Switzerland Defined Benefit Plan

The Company maintains a pension plan covering employees of our Swiss subsidiary (the “Swiss Plan”). Employer and employee contributions are made to the Swiss Plan based on various percentages of salary and wages that vary according to employee age and other factors. Employer contributions to the Swiss Plan were $5 million and $4 million for the years ended June 30, 2025 and 2024, respectively. Net periodic pension cost is not material for any year presented.

The underfunded pension liability was $25 million and $17 million as of June 30, 2025 and 2024, respectively. The pension adjustment amount recognized in accumulated other comprehensive income (loss) was a $7 million decrease for both fiscal years ended June 30, 2025 and 2024. The accumulated benefit obligation was $141 million as of June 30, 2025, compared to $106 million as of June 30, 2024.

Other Defined Benefit Plans

As a result of the Coherent, Inc. acquisition on July 1, 2022, we assumed all assets and liabilities of defined benefit plans in the U.S., Germany, South Korea, Japan, Spain, and Italy (“other plans”). As is the customary practice with European and Asian companies, the plans are unfunded, with the exception of the Spanish plan which is partially funded. The U.S. qualified plan is also partially funded. Any new employees hired after January 1, 2007, are not eligible for the U.S. qualified and nonqualified plans. Effective August 31, 2018, both of the U.S. plans were amended to freeze all future compensation benefit accruals. Any new employees hired after 2000 are not eligible for the primary German pension plans. For two of the German plans and the U.S. qualified plan, unrealized gains and losses are recognized as a component of other comprehensive income (loss) within shareholders’ equity. For the other plans, we have elected to recognize all actuarial gains and losses on these plans immediately, as incurred.

Liabilities and expense for pension benefits are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality). All of these assumptions were based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions would impact future expense recognition and the cash funding requirements of our defined benefit plans.

For the other plans, employer contributions in the years ended June 30, 2025 and June 30, 2024 were $3 million and $2 million, respectively, and net periodic pension cost was not material in either year. The underfunded pension liability was $37 million and $34 million as of June 30, 2025 and June 30, 2024, respectively. The pension adjustment amount recognized in accumulated other comprehensive income (loss) was a $1 million increase and a $1 million decrease for the fiscal years ended June 30, 2025 and June 30, 2024, respectively. The accumulated benefit obligation was $47 million and $44 million as of June 30, 2025 and June 30, 2024, respectively.

Estimated future benefit payments under all plans are estimated to be as follows ($000):

Year Ending June 30,
2026	$	10,400
2027	9,400
2028	10,100
2029	11,500
2030	12,100
Next five years	66,800

Note 18.        Commitments and Contingencies

We have purchase commitments for materials and supplies as part of the ordinary conduct of business. A portion of the commitments are long-term and are based on minimum purchase requirements. Certain short-term raw material purchase commitments have a variable price component which is based on market pricing at the time of purchase. Due to the proprietary nature of some of our materials and processes, certain contracts may contain liquidated damage provisions for early termination. We do not believe that a significant amount of liquidated damages are reasonably likely to be incurred under these commitments, based upon historical experience and current expectations. Total future purchase commitments held by Coherent as of June 30, 2025 were $945 million in fiscal 2025 and $147 million thereafter.

Regulatory Matters

In January 2025, we received an inquiry from BIS concerning past product sales to Huawei; we are cooperating with BIS’s inquiry and conducting an internal review of those sales to determine what products are subject to EAR and consequently restricted for export, reexport, and transfer when Huawei is a party to the transaction. We have stopped shipping products to Huawei. We are in discussions with BIS regarding past product sales and cannot predict the outcome of those discussions. While we have received requests for additional information in this matter, we have not yet received any determination from BIS. In the event that we are found to have violated the EAR, we may be required to incur significant penalties and/or costs or expense as a result of the inquiry and to comply with, or remedy any violations of these regulations, but at this time, we are unable to determine an estimate or range of loss.

86

The Company uses a portfolio approach to release the income tax effects in AOCI related to interest rate instruments and pension and postretirement benefits. Under this approach, the income tax effects are released from AOCI based on the pre-tax adjustments to interest rate instruments and pension liabilities or assets recognized within AOCI. Any tax effects remaining in AOCI are released only when the entire portfolio of the interest rate instruments or pension and postretirement benefits is liquidated, sold or extinguished.

Note 20.        Restructuring Plans

2023 Restructuring Plan

On May 23, 2023, the Board of Directors approved the 2023 Plan which includes site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. These restructuring actions were intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model. We evaluate restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations, and ASC 712, Compensation-Nonretirement Post-Employment Benefits (ASC 712).

In fiscal 2025, these activities resulted in $53 million of charges primarily for impairment losses associated with the sale of our Newton Aycliffe business, impairment of ROU assets, employee termination costs, site move cost and accelerated depreciation. In fiscal 2024, these activities resulted in $27 million of charges primarily for acceleration of depreciation, write-off of property and equipment, and site move costs. In fiscal 2023, these activities resulted in $119 million of charges primarily for employee termination and the write-off of property and equipment, net of $65 million from reimbursement arrangements.

Activity and accrual balances for the 2023 Plan were as follows ($000):

	Severance		Asset Write-Offs		Other		Total Accrual
Balance - June 30, 2023	$	64,379	$	—	$	—	$	64,379
Restructuring charges (recoveries)	(129)		11,658		15,527		27,056
Payments	(13,189)		—		—		(13,189)
Asset write-offs and other	—		(11,658)		(15,527)		(27,185)
Balance - June 30, 2024	51,061		—		—		51,061
Restructuring charges	6,123		24,010		22,864		52,997
Payments	(12,954)		—		—		(12,954)
Asset write-offs and other	—		(24,010)		(22,864)		(46,874)
Balance - June 30, 2025	$	44,230	$	—	$	—	$	44,230

At June 30, 2025, $11 million and $34 million of accrued severance related costs were included in other accrued liabilities and other liabilities on our Consolidated Balance Sheet, respectively, and are expected to result in cash expenditures through fiscal 2028. The current year severance related net charges are primarily comprised of accruals and adjustments for severance pay for employees being terminated due to the consolidation of certain manufacturing sites, with severance recorded in accordance with ASC 712. The fiscal 2024 severance related recoveries are primarily comprised of adjustments to accruals for severance pay for employees being terminated due to the consolidation of certain manufacturing sites, with severance recorded in accordance with ASC 712.

By segment in fiscal 2025, $12 million, $38 million and $3 million of restructuring costs were incurred in the Networking, Materials and Lasers segments, respectively. By segment in fiscal 2024, $(4) million, $28 million and $4 million of restructuring costs (recoveries) were incurred in the Networking, Materials and Lasers segments, respectively. Restructuring charges and recoveries are recorded in Restructuring charges in our Consolidated Statements of Earnings (Loss).

2025 Restructuring Plan

Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of the Company’s business, the Company’s management approved the 2025 Plan. In connection therewith, the Company expects to incur charges for related severance and benefits, lease and contract termination costs, asset write-offs, facilities move and other restructuring costs. We evaluate restructuring charges in accordance with ASC 420 and ASC 712.

In fiscal 2025, these activities resulted in $107 million of charges primarily for the write-off of property and equipment and ROU assets, employee and contract termination costs. We expect the restructuring actions to be substantially completed by the end of fiscal 2026. However, the actual timing and costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material.

Activity and accrual balances for the 2025 Plan were as follows for fiscal 2025 ($000):

87

	Severance		Asset Write-Offs		Other		Total Accrual
Balance - June 30, 2024	$	—	$	—	$	—	$	—
Restructuring charges	23,983		59,068		24,033		107,084
Payments	(7,261)		(48,574)		(4,136)		(59,971)
Balance - June 30, 2025	$	16,722	$	10,494	$	19,897	$	47,113

At June 30, 2025, $17 million of accrued severance related costs were included in other accrued liabilities and are expected to result in cash expenditures primarily through fiscal 2026. The current year severance related net charges are primarily comprised of accruals for severance and pay for employees being terminated due to the consolidation of certain manufacturing sites as well as workforce reductions, with severance recorded in accordance with ASC 712. At June 30, 2025, total liabilities for asset write-offs and other contract costs of $19 million and $12 million were included in other accrued liabilities and other liabilities on our Consolidated Balance Sheet, respectively.

By segment, in fiscal 2025, $65 million of restructuring costs were incurred in the Materials segment, $23 million were incurred in the Networking segment, $12 million were incurred in the Lasers segment, and $7 million were incurred in the Corporate segment. Restructuring charges and recoveries are recorded in Restructuring charges in our Consolidated Statements of Earnings (Loss).

Note 21.        Assets Held-for-Sale

In the fourth quarter of fiscal 2025, management entered into non-binding agreements to sell several entities. As a result of classifying these entities as held-for-sale, we recorded non-cash impairment charges of $85 million in our Lasers segment to Impairment of assets held-for-sale in our Consolidated Statements of Earnings (Loss) in the fourth quarter of fiscal 2025 to reduce our carrying value in these entities to fair value. Current assets and current liabilities held for sale are recorded in Prepaid and other current assets and Other accrued liabilities, respectively, in our Consolidated Balance Sheet. Noncurrent assets and noncurrent liabilities held for sale are recorded in Other assets and Other liabilities, respectively, in our Consolidated Balance Sheet. Assets and liabilities held-for-sale are in our Lasers and Materials segments.

On August 2, 2025, we entered into an agreement to sell our aerospace and defense business for $400 million. We expect to close this transaction in the first quarter of fiscal 2026. Although the assets of this business were classified as held-for-sale at June 30, 2025, we did not record an impairment loss on this business as we expect to recognize a gain in the first quarter of fiscal 2026 when the sale of the business closes.

Current and noncurrent assets and liabilities classified as held for sale as of June 30, 2025 related to these entities are as follows ($000):

	June 30, 2025
Accounts receivable	$	43,353

Item 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management evaluated, with the participation of the Company’s Chief Executive Officer, and the Company’s Chief Financial Officer and Treasurer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) as of the end of the period covered by this Annual Report on Form 10-K. The Company’s disclosure controls were designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. However, the controls have been designed to provide reasonable assurance of achieving the controls’ stated goals. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2025, the Company’s disclosure controls and procedures were effective.
